Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, for convenience of description, an XYZ coordinate system of the packaging machine is defined, where, in a case where no description is made on the contrary, the X direction is a longitudinal direction corresponding to a front-back direction, the Y direction is a transverse direction corresponding to a left-right direction, and the Z direction is a vertical direction corresponding to an up-down direction, where, when the packaging machine is in a use state, the vertical direction is parallel to a gravity direction, the gravity direction points to a down direction, and when a user faces forward, a left hand corresponds to a left direction, and a right hand corresponds to a right direction. In addition, the orientation pointing to the baler is "in", whereas "out", whereas "far and near" are defined based on the distance to the reference. Furthermore, the ordinal numbers "first" and "second" used herein are used merely to distinguish one element from another, and do not define the ordinal or importance. The following description refers to the accompanying drawings, in which like reference characters designate the same or similar elements throughout the different views.

Before proceeding with a detailed description of embodiments of the present disclosure, for a better understanding of the present disclosure, the inventive concepts are summarized herein as follows:

in order to solve the problem of manpower occupation of takeout packaging mentioned in the background section, the takeout packaging machine suitable for being applied to the field of takeout ordering is provided, in the operation process of the takeout packaging machine, a prefabricated packaging bag such as a plastic bag is not used, a packaging bag is made on the spot by using a film, the takeout article (such as a meal after boxing) is packaged and packaged in the manufacturing process of the packaging bag, and the whole process is completed by a machine without manual bagging operation.

External belt article packaging machine

According to a particular embodiment provided by a first aspect of the present disclosure, there is provided an outer belt article baler. Fig. 1 to 27 show a first embodiment, and fig. 28 to 52 show a second embodiment. Referring to fig. 1-52, the outer belt article baler includes a moving platform 200, a film supply module 300, and a bagging module 400.

Wherein the mobile platform 200 provides a load-bearing plane for placing the out-of-band item 1. The film supply module 300 supplies the film 91. Through the lift removal of moving platform 200, cooperation membrane material supply module 300 can realize the packing in advance of takeout article 1 to the operation of film 91, promptly: the carrying plane serves as an operation table, and after the film 91 is laid on the carrying plane of the moving platform 200 at the initial position, the user can stack the out-tape item 1 on the film 91 and then the moving platform 200 moves down. As the distance between the moving platform 200 and the film supply module 300 increases in the vertical direction, since the film portions on both sides of the outer band article 1 (both sides in the longitudinal direction of the film 91 are understood to be front and rear sides) are still held by the film supply module 300, the front end portion 92 of the film 91 on the front side of the outer band article 1 and the rear end portion 93 on the rear side of the outer band article 1 are folded upward to both sides of the outer band article 1, and thus, the film 91 forms edge openings on both the left and right sides and the upper side extending out of the outer band article 1.

It will be appreciated here that only a certain length of film 91 is required to pack the outer tape article 1, and therefore the film supply module 300 need only provide a film 91 of the required length in one packing operation. The film 91 with the desired length can be provided by the film supply module 300 in any suitable manner, for example, a section of film with a specific length (i.e., a predetermined length, which can also be referred to as a desired length) can be laid on the carrying surface, or the film supply module 300 can continue to lay the film from the beginning of laying the film 91 on the carrying surface until the film is cut off when the film is laid to the desired length. The above-described pre-packaging operation may also be performed simultaneously during the film laying process. Thus, the initial configuration of the film 91 in the film supply module 300 may be a section of film having a specific length, or may be a continuous roll of film wound on a spool. The film 91 used in the present disclosure may be any commercially available packaging material, for example, a degradable transparent or non-transparent plastic film paper, and a logo such as a trademark or a pattern may be printed on an outer surface (an inner surface facing the outer article 1) of the film 91 in a personalized manner.

Thereafter, the opening of the edges of the front, rear, side, and upper sides of the outer band article 1 can be sealed by operating the bag making module 400, thereby forming a package in which the outer band article 1 is packed together by the film 91 described above. After which the user may take the package away. Therefore, the outer belt article packaging machine provided by the first aspect of the present disclosure can replace manual packaging operation, and is suitable for being applied to any other suitable scenes besides the selling field, such as hospital pharmacies, supermarkets and the like.

The film 91 is considered to be in a pre-packaged state until the mobile platform 200 starts to descend to the packaging bag making module 400 for sealing after the outer band article 1 is stacked. When the mobile platform 200 descends to a certain position, the bag making module 400 is adapted to perform a sealing operation, and for the convenience of description, the position is defined as a sealing position, that is: the bag making module 400 is adapted to perform a sealing operation when the mobile platform 200 moves down from the initial position to the sealing position.

In order to facilitate an intuitive understanding of the working principle of the outer belt article wrapping machine provided by the first aspect of the present disclosure, the wrapping process will be described herein with reference to fig. 53a to 53 f:

first, the film 91 is supplied through the film supply module 300 and laid on the carrying plane of the moving platform 200 at the initial position, as shown in fig. 53 a.

The out-carrying item 1 may then be stacked on the film 91 laid on the moving platform 200, as shown in fig. 53 d.

Then, the mobile platform 200 moves down. In this process, since the film supply module 300 holds the front and rear ends of the film 91 and the Z-position of the holding points K (indicated by triangular symbols in the drawing) respectively corresponding thereto is not changed, the front end portion 92 and the rear end portion 93 of the film 91 are folded upward with respect to the intermediate portion 94 located below the outer belt article 1, as shown in fig. 53 e. After the front and rear end portions are folded, the film 91 will form edge openings on the left and right sides and the upper side of the outer belt article 1.

Thereafter, the movable platform 200 is lowered into position (i.e., to the sealing position described above), and after the movable platform 200 is stopped, the bag making module 400 seals the edge openings of the film 91 on the left and right sides and the upper side of the outer band article 1 to obtain a package, as shown in fig. 53 f.

Thus, the basic operations necessary for packaging the outer-band article 1 are completed by the cooperation of the moving platform 200, the film material supply module 300 and the bag making module 400.

In the film material supply module 300, the position of the holding point K in the longitudinal direction provided by the holding module can be moved correspondingly with the folding of the film 91, or the position of the holding point K in the longitudinal direction is not changed, but even if the film 91 moves during the folding of the film 91, the holding point K always clamps and gives a certain pressing force to the film 91, so that the front end portion 92 and/or the rear end portion 93 of the film 91 are not suspended/swung freely due to the loss of support. In addition, in the packaging process, the holding point K of the film material supply module 300 is not suitable for releasing the front end and the rear end of the film 91 too early, otherwise, the film 91 loses the restraint to cause the sealing edge or the sealing failure, but is not suitable for too late, otherwise, the conveying or the taking out of the package is influenced.

For the bag making module 400, the sealing manner may be determined according to the material properties of the film 91, for example, the plastic film may be heat sealed; the method can also be determined according to actual requirements, such as sewing, stapling and the like. The extent of the seal can be designed as desired, for example, the left and right sides can be sealed in a continuous line, and the top side can be sealed in a spot or broken line, so that the recipient can know that the package has not been opened before delivery.

The above is the core technical solution based on the basic concept of the present disclosure.

In addition, the above-mentioned moving platform 200, the film material supplying module 300 and the bagging module 400 may be configured in any suitable manner without departing from the spirit of the present disclosure, and of course, other modules, mechanisms, components or structures that have positive effects on the above-mentioned core technical solution may be introduced, and the present disclosure is not limited in particular.

For example, the bag making module 400 may include a pressing mechanism by which the edge openings may be first pressed prior to sealing, taking into account flatness and success. This pressing operation may be performed before sealing, for example, during the process of moving the movable platform 200 down from the initial position. And this pressing operation is adapted to remain at least until the sealing operation is started. Accordingly, it is appropriate to initiate such a stitching operation when the movable platform 200 is moved down to a position above the sealing position, which for ease of description is defined as the binder position.

For the way of providing the film 91 of a specific length in the form of a film roll, when the pressing operation is started, it can be understood that the length of the film 91 that has been fed out is sufficient, and therefore, the film material supply module 300 can cut the film 91 at this time, and even, the film material supply module 300 can release the holding of the front end of the film 91, even the holding of the rear end of the film 91, under the action of the edge pressing mechanism.

Also for example, considering that during the pre-packaging process, it is possible that the weight of the outer article 1 stacked on the moving platform 200 is not enough to overcome the holding force of the film supply module 300 on both ends of the film 91 and cannot move down with the moving platform 200, the bagging module 400 may include a bottoming mechanism 48 mounted on the moving platform 200 for pulling the middle portion 94 of the film 91 under the outer article 1 to move down with the moving platform 200.

In addition, for the completed bag, since the weight is almost concentrated on the middle portion 94, it is considered that the area of the middle portion 94 is larger than the area of the bottom surface of the outer belt article 1, so that the force-bearing surface can be increased to provide better support to the outer belt article. This can be achieved by folding the outer tape article 1 before it is placed on the film 91, wherein "folding" is understood to mean folding a portion of the film, for example, providing a laterally extending groove on the carrying surface of the mobile platform 200, in which groove the desired length of the film is folded, for example, folding a V-shape, a W-shape, etc. The groove is designed to avoid the folded film portion from affecting the placement of the outer-belt article, and the movable platform 200 can provide a relatively flat bearing surface for the outer-belt article 1 by hiding the folded film portion into the groove. Here, the above-described pulling and bottoming operations for the intermediate portion may be both performed by the above-described bottoming mechanism 48.

In a specific embodiment provided by the first aspect of the present disclosure, the outer belt article wrapping machine may include a body 100 defining an outer belt article input port 1001 and a parcel output port 1002, and the moving platform 200, the film material supply module 300, and the bagging module 400 described above are all disposed in the body 100.

In the specific embodiment provided in the first aspect of the present disclosure, the moving direction and trajectory of the mobile platform 200 with respect to the fuselage 100 may be designed according to the arrangement of the orientation and the arrangement of the distance between the input port 1001 and the output port 1002. Here, for convenience of description, the mobile platform 200 is defined to have a first position where a user can stack out-tape items 1 from the input port and a second position where the user can obtain packages from the output port 1002. In some embodiments, when the mobile platform 200 is located at the initial position, the user can stack the brought article 1 on the carrying plane of the mobile platform 200 through the input port 1001, and thus the initial position is the first position. In other embodiments, when the mobile platform 200 is located at the sealing position, the user can remove the package from the outlet 1002, and thus the sealing position is the second position. In still other embodiments, when the mobile platform 200 is in the initial position, the user cannot stack the takeaway item 1 thereon, and thus, after laying the film 91, the mobile platform 200 and the film 91 thereon can be moved to the first position suitable for the user to stack the takeaway item 1. In still other embodiments, the packages are not available to the user when the mobile platform 200 is in the sealing position, and thus, after sealing, the mobile platform 200 and the packages thereon may be moved from the sealing position to a second position to facilitate the user to take the packages directly or to send them out by a second conveyor mechanism 52 described below.

The input port 1001 may be opened on the top surface of the body 100 so that the user can easily stack the takeout article 1 without bending. For the cargo outlet 1002, it can be opened at the side of the body 100, so as to facilitate the user to take away the cargo. In some embodiments, since installation and operation spaces for the film supply module 300 and the bagging module 400 need to be left in the body 100, the input port 1001 on the top surface of the body 100 may be disposed at a distance from the edge, and thus, may be vertically offset from the output port 1002 by a predetermined distance. In this case, the mobile platform 200 may be configured to move laterally and/or longitudinally to move closer to the outlet 1002 to allow the user to reach for the package in the outlet 1002. It is also possible to design the movable platform 200 to move only in the vertical direction, and a conveying module is provided in the packaging machine, so that the packages carried on the movable platform 200 at the second position can be conveyed to the delivery port 1002 through the conveying module. In some embodiments, in order to make the track for the transportation module to transport the parcel from the second position to the delivery port 1002 relatively simple, it may be that the input port 1001 and the delivery port 1002 are designed to be aligned in the transverse or longitudinal direction, and then the transportation module can transport the parcel in a straight line, which may simplify its own structural design for the transportation module. Alternatively, in order to allow sufficient installation space and operating space for the film supply module 300 and the bagging module 400 and the moving platform 200 in the machine body 100, the input port 1001 and the output port 1002 may be designed to be aligned in the longitudinal direction when the transverse dimension of the bagging machine is smaller than the longitudinal dimension, such that the above-mentioned transport module is a longitudinal transport module 500, which may include a first transport mechanism 51 and a second transport mechanism 52, wherein the first transport mechanism 51 is adapted to transport the packages on the moving platform 200 forward in the longitudinal direction (i.e., toward the output port 1002), alternatively, the first transport mechanism 51 may be disposed on the moving platform 200, providing the above-mentioned carrying plane, and may be configured as a crawler conveyor, for example. The rear end of the second conveying mechanism 52 is adapted to abut against the movable platform 200 at the second position to receive the package conveyed by the first conveying mechanism 51, while the front end of the second conveying mechanism 52 extends to or beyond the outlet 1002 for the user to conveniently take the package without bending over or probing his/her hands or body. If the first conveying mechanism 51 is disposed on the movable platform 200, when the movable platform 200 is located at the second position, the rear end of the second conveying mechanism 52 is adjacent to the front end of the first conveying mechanism 51, so that the parcels can be smoothly transferred from the first conveying mechanism 51 to the second conveying mechanism 52. Here, in order to enable the outer-band article 1 to be conveyed smoothly even in a wrapped package formed after being wrapped, the carrying surface and the conveying locus of the first conveyor 51 and the carrying surface and the conveying locus of the second conveyor 52 may be designed to be perpendicular to the vertical direction. Accordingly, it is suitable that the first conveyor mechanism 51 and the second conveyor mechanism 52 are configured as caterpillar conveyors, but of course, other suitable or desired conveyors may be configured, and the present disclosure is not limited thereto.

In a second embodiment provided by the third aspect of the present disclosure, referring to fig. 41, the bag edge heat-sealing mechanism 41 is configured as an impulse type heat-sealing mechanism, the first bag edge heat-sealing unit includes a first bead 4121, the second bag edge heat-sealing unit includes a second bead 4122, the first bead 4121 and the second bead 4122 are aligned in a longitudinal direction, at least one of the first bag edge heat-sealing unit and the second bag edge heat-sealing unit further includes a heat-cutting resistance wire 4123 tension-mounted on the first bead 4121 and/or the second bead 4122, and the heat-cutting resistance wire 4123 is arranged on a heat-sealing surface where the first bead 4121 and/or the second bead 4122 are opposite to each other. When the heat-sealed surfaces of the first bead 4121 and the second bead 4122 are pressed from the front and rear sides of the film, the edges of the bag can be sealed by energizing the heat-cutting resistance wire. Here, since the hot-cutting resistance wire is thin, the width of the seal mark 97 (see fig. 53 f) formed on the bag after sealing is relatively small, and the aesthetic appearance of the bag can be improved to some extent. In addition, to provide better contact between the film 91 and the sealing surface, an elastomeric cushion may be added to each sealing surface of the two beads.

In addition, the hot-cutting resistance wire 4123 may be installed in such a manner: referring to fig. 42 and 43, a first resistance wire bracket 4124 may be fixedly disposed on one end surface of the first pressing bar 4121 or the second pressing bar 4122, a second resistance wire bracket 4125 is movably disposed on the other end surface, one end of the thermal cutting resistance wire 4123 is fixed to the first resistance wire bracket 4124, the other end is fixed to the second resistance wire bracket 4125, and the second resistance wire bracket 4125 is connected to the corresponding end surface of the first pressing bar 4121 or the second pressing bar 4122 through a tensioning structure.

Wherein the tensioning structure may be constructed in any suitable manner. Alternatively, referring to fig. 43, the tensioning structure comprises a screw 4126 and a nut 4127, the screw 4126 passes through the second resistance wire bracket 4125 and the corresponding end of the first or

second bead

4121, 4122 to be connected with the nut 4127, and the axial direction of the screw 4126 is parallel to the extending direction of the first or

second bead

4121, 4122. By loosening the screw 4126, the thermal cutting resistance wire 4123 can be tightened against the first bead 4121 or the second bead 4122.

Here, for the first mounting plate 461 and the second mounting plate 462, both mounting plates may be configured with vertically extending ends in order to provide a sufficient mounting position for the heating block or the pressing bar in the above-described bag-edge heat-sealing mechanism 41.

In the particular embodiment provided by the third aspect of the present disclosure, the bag top heat seal 42 may be configured in any suitable manner. Alternatively, referring to fig. 22, 44 and 45, the bag top heat sealing mechanism 42 includes a heat sealing bottom plate 421 and a heat sealing heating block 422 capable of being fitted to each other, and a bag top heat sealing actuating unit 423, the heat sealing bottom plate 421 is fixedly disposed at a middle portion of one of the first mounting plate 461 and the second mounting plate 462, the heat sealing heating block 422 is movably disposed at a middle portion of the other of the first mounting plate 461 and the second mounting plate 462, and is capable of moving toward or away from the heat sealing bottom plate 421 by the actuation of the bag top heat sealing actuating unit 423 to heat seal or reset the upper side portion. The bag edge and bag top sealing operation may be described herein in connection with a bag edge heat seal 41. When the first mounting plate 461 and the second mounting plate 462 are brought close to each other so that the first bag edge heat-sealing unit and the second bag edge heat-sealing unit in the bag edge heat-sealing mechanism 41 are in contact with each other, a certain space or clearance may also exist between the heat-sealing bottom plate 421 and the heat-sealing heating block 422, and at this time, the bag top heat-sealing actuator 423 may be operated to drive the heat-sealing heating block 422 to move toward the heat-sealing bottom plate 421 and press against the heat-sealing bottom plate 421. Thus, the sealing of the edges of the bag may be completed or initiated prior to the sealing of the top of the bag.

In addition, to facilitate the bag opening and retrieving operation, the temperature of the bag top seal may be lower than the temperature of the bag side seal, so that the place where the bag top seal is sealed is easily opened.

Further, referring to fig. 45, the heat sealing heating block 422 has a working surface facing the heat sealing bottom plate 421, and a plurality of protrusions 4221 are formed on the working surface to form a plurality of heat sealing points to seal the upper portion at the time of heat pressing. The cross-section of the protrusions 4221 determines the shape of the pouch top heat-seal trace 96 (shown with reference to fig. 53 f), and thus, the cross-sectional shape of the protrusions 4221 may be designed to obtain a desired shape of the pouch top heat-seal trace, for example, a circle, an ellipse, a polygon, a line, etc., to which the present disclosure is not particularly limited.

Wherein plurality of protuberances 4221 may be arranged in any suitable manner, and optionally, plurality of protuberances 4221 are arranged linearly in a transverse direction at intervals from one another to achieve a clean top closure of the pouch.

In addition, if the handle hole 98 is provided, the heat-seal marks 96 (see fig. 53 f) formed on the upper portion when the plurality of protrusions 4221 are heat-pressed may be located on the lower side of the handle hole 98 so as not to leak the small carry-out article 1 from the handle hole 98.

In some embodiments provided in the third aspect of the present disclosure, the film 91 may be designed with a handle hole 98 at an upper portion located above the outer belt article 1 for the convenience of a human hand to grasp. Alternatively, the handle aperture 98 may be self-contained with the film. It is also possible to form the handle hole 98 on site, so that the bag making module 400 can punch out the handle hole 98 (see fig. 53 f) by the handle punching mechanism 43 on the upper side portion of the folded-back front and rear end portions above the external article 1, thereby ensuring that the handle holes 98 on the front end portion 92 and the rear end portion 93 are aligned, which is advantageous for improving the user's gripping experience.

In the embodiment provided in the third aspect of the present disclosure, the handle punching mechanism 43 may punch the handle holes 98 again while ensuring that the front and rear end portions of the film do not move relative to each other, so as to ensure that the handle holes 98 punched in the front and rear end portions are aligned. For example, when the heat-sealing by the bag edge heat-sealing mechanism 41 is started or after the heat-sealing is completed, or when the heat-sealing by the bag top heat-sealing mechanism 42 is started or after the heat-sealing is completed, that is, the front and rear end portions of the film are not moved relatively by the bag edge heat-sealing mechanism 41 or the bag top heat-sealing mechanism 42. It is also possible to do this by means of an additional edge-pressing mechanism (described in detail below), in which case the operations of the handle punching mechanism 43 and of the edge and top heat-sealing

mechanisms

41 and 42 are out of sequence, or even all three.

In some embodiments provided in the third aspect of the present disclosure, referring to fig. 22 and 44, the handle punching mechanism 43 may include a punch 431 and a die holder 432 capable of cooperating with each other, the die holder 432 is fixedly disposed at a middle portion of one of the first mounting plate 461 and the second mounting plate 462, the punch 431 is movably disposed at a middle portion of the other of the first mounting plate 461 and the second mounting plate 462, and is capable of moving toward a direction approaching or separating from the die holder 432 under the driving of the die holder 433 to punch or reset the handle hole 98 (refer to fig. 53 f) at an upper portion.

The shape of the handle hole 98 is determined by the shape of the punch 431, and alternatively, the handle hole may be in the shape of a long round hole extending in the transverse direction so as to facilitate the insertion of a user's hand.

In the process of punching the handle, since the punching between the punch block 431 and the die holder 432 applies a shearing force to the film 91, the film 91 is likely to wrinkle during punching, and the flatness of the edge of the handle hole 98 is damaged. To this end, referring to fig. 44, the handle punching mechanism 43 may include a film pressing plate 434 and a pressing plate actuating unit 435, the film pressing plate 434 being movably mounted to a first mounting plate 461 or a second mounting plate 462 to which the punch 431 is mounted so as to be movable toward or away from the die holder 432 by the pressing plate actuating unit 435 to press the upper portion against the die holder 432 or to reset it. In this case, the punch 431 may punch the film 91 to the die holder 432 after the film press 434 presses the film, so as to obtain the handle hole 98 with a smooth edge.

The film platen 434 may be configured in any suitable shape, among others. Alternatively, the film press 434 provides compression around the entire circumference of the ram 431, and thus, to avoid interference with the ram 431, the film press 434 is perforated with ram clearance holes through which the ram 431 can move, as shown with reference to fig. 45.

Thus, the bag edge heat sealing, bag top heat sealing and handle punching operations can be performed while the movable platform is in the sealing position. In some embodiments, the bag edge heat seal mechanism and the bag top heat seal mechanism may be operated simultaneously.

Further, in the manufacturing process of the packaging bag, since the outer tape article 1 is placed therein, the flatness problem of the film 91 is faced in the sealing operation of the bag edge and the bag top. To this end, in the embodiment provided in the third aspect of the present disclosure, the bag making module may include a pressing mechanism to press the films 91 on the left and right sides and the upper side of the outer tape object 1 before the bag edges and the bag top are sealed, so that the films 91 are not wrinkled again during the operation of the bag edge heat-sealing mechanism 41 and the bag top heat-sealing mechanism 42.

As shown in fig. 24, 25, 46 and 47, the edge pressing mechanism may include two bag edge pressing mechanisms 44, the two bag edge pressing mechanisms 44 are arranged on the lateral side of the moving platform 200 in the transverse direction, symmetrically with respect to the moving platform 200, the bag edge pressing mechanisms 44 on each side are located outside the bag edge heat sealing mechanism 41 on the same side, and the bag edge pressing mechanisms 44 are used for laminating and pressing the side edge parts of the films on the same side of the outer belt article 1 after the front and rear end parts are folded in half.

The bag edge compression mechanism 44 may be configured in any suitable manner. Alternatively, referring to fig. 24, 25, 46, and 47, the bag-side pressing mechanism 44 may include first and second

pressing blocks

441 and 442 each movably mounted to a respective pressing-side bracket 447, and first and second pressing-

side actuating units

443 and 444 for the first and second

pressing blocks

441 and 442, the first and second

pressing blocks

441 and 442 being movable toward and away from each other to press or release the side edge portions by being driven by the first and second pressing-

side actuating units

443 and 444.

In order to improve the pulling phenomenon when the film 91 is in contact with the pressing blocks in the pressing process, at least one of the two pressing surfaces of the first pressing block 441 and the second pressing block 442 facing each other is provided with a rolling friction structure 445, so that the sliding friction between the film and the clamping blocks is changed into rolling friction, and the friction force between the film and the clamping blocks is reduced.

The rolling friction structure may be configured in any suitable manner, alternatively, as shown with reference to fig. 23, 24 and 46, the rolling friction structure 445 includes a plurality of rollers that are free to rotate about a transverse pivot axis. It is also possible for the rolling friction structure to be designed as a ball.

In addition, referring to fig. 47, the first and second hold-down

actuation units

443, 444 are respectively mounted on respective corresponding hold-down brackets 447, the hold-down brackets 447 are fixedly connected to the body 100, the output of the first hold-down actuation unit 443 is fixedly connected to the hold-down block mounting bracket 446 of the first hold-down block 441, the output of the second hold-down actuation unit 444 is fixedly connected to the hold-down block mounting bracket 446 of the second hold-down block 442, and a hold-down adjustment mechanism is provided between the hold-down brackets 447 and the hold-down block mounting bracket 446 and is configured to limit the moving stroke of the respective hold-down block in the longitudinal direction under the driving of the respective actuation unit, so as to adjust the interaction force between the first and second hold-

down blocks

441, 442 when they hold down the side edge portions.

Wherein the binder adjustment mechanism may be configured in any suitable manner. Alternatively, referring to fig. 37 and 47, the blank holder adjusting mechanism includes a threaded rod 448 and an adjusting nut 449, the threaded rod 448 is extended in the longitudinal direction and freely movably disposed through the blank holder 447 and the compact block mounting bracket 446 in the longitudinal direction, both end portions of the threaded rod 448 are screw-fitted with the adjusting nuts 449, one of the adjusting nuts 449 is disposed on a side of the blank holder 447 facing away from the compact block mounting bracket 446, and the other adjusting nut is disposed on a side of the compact block mounting bracket 446 facing away from the blank holder 447, whereby the maximum stroke of the first compact block 441 or the second compact block 442 in the longitudinal direction can be correspondingly restricted by adjusting the pitch of the two adjusting nuts 449.

The first and second hold-down

actuation units

443, 444 may be configured in any suitable manner, and alternatively may be configured as piston cylinders with piston rods attached to corresponding hold-down blocks.

In particular embodiments provided by the third aspect of the present disclosure, the hold-down mechanism may include a bag top hold-down mechanism 45, the bag top hold-down mechanism 45 being used to hold the two layers of film stock in the upper section against each other.

The bag top hold down mechanism 45 may be configured in any suitable manner. In a first embodiment provided by the third aspect of the present disclosure, referring to fig. 23 and 24, the bag top pressing mechanism 45 includes a pressing wheel set including a first bag top pressing wheel 4511 and a second bag top pressing wheel 4512 both capable of rotating around a transverse pivot axis, the first bag top pressing wheel 4511 and the second bag top pressing wheel 4512 are aligned in a vertical direction and a longitudinal direction and fixed in position relative to the machine body 100, and a pressing wheel set is correspondingly disposed on an upper side of each pressing mechanism. After the front and rear end portions of the film are folded in half, one portion is positioned between the two bag press rollers, and the films 91 of the front and rear end portions can be brought together by the engagement of the two bag press rollers, as shown in fig. 53 e. In order to facilitate the arrangement of the first bag pressing wheel 4511, the first bag pressing wheel 4511 may be fixedly connected to the machine body 100 through a bag top pressing mounting plate 453, as shown in fig. 25.

In a second embodiment provided by the third aspect of the present disclosure, referring to fig. 46 and 47, the bag top pressing mechanism 45 includes a bag top pressing rod 4521, the bag top pressing rod 4521 includes a rod core extending along the transverse direction and a rolling member freely rotatably sleeved on the rod core, a bag top pressing rod 4521 is provided on the two first pressing blocks 441, two end portions of the rod core are correspondingly fixedly connected to the top end portions of the first pressing blocks 441, another bag top pressing rod 4521 is provided on the two second pressing blocks 442, and two end portions of the rod core are correspondingly fixedly connected to the top end portions of the second pressing blocks 442. Under the driving of the first and second edge pressing actuating

units

443, 444, as the two pressing blocks approach each other or even press against each other, the two bag top pressing rods 4521 thereon approach each other or even press against each other, so that the film portions at the front and rear ends of the upper side of the outer tape object 1 can be made to approach each other or even fit, as also shown in fig. 53 e. The rolling contact between the film 91 and the roller in the bag top bar 4521 not only reduces the friction between the two, but also provides support and guidance along the entire length of the bag top bar 4521 itself, which reduces the likelihood of wrinkling of the film 91 during movement.

In the bag making process, the film used has a central portion 94 between the front and

rear end portions

92, 93, the central portion 94 being adapted to hold the outer belt article 1 on the mobile platform 200, as shown in reference to fig. 53 e. In view of this, in the specific embodiment provided in the third aspect of the present disclosure, the bagging making module 400 may include two bottom-building mechanisms 48 for making the folded structure 95 (shown in fig. 53 e) in the middle portion 94, and the two bottom-building mechanisms 48 are mounted on the side end portion of the moving platform 200 symmetrically with respect to the moving platform 200 in the lateral direction, and the folded structure 95 has at least two film portions stacked.

In particular embodiments provided by the third aspect of the present disclosure, the underfloor mechanism 48 may be configured in any suitable manner. Alternatively, as shown in fig. 27 and fig. 49 to 52, the bottoming mechanism 48 includes a bottoming bracket, a first bottoming actuating unit 482, and a first rod piece 483 and a second rod piece 484 both extending laterally inward, the first rod piece 483 being fixedly provided to the bottoming bracket, the second rod piece 484 being movably provided to the bottoming bracket to be movable between a first bottoming position (shown in fig. 53 a) higher than the first rod piece 483 and a second bottoming position (shown in fig. 53 b) lower than the first rod piece 483 by the actuation of the first bottoming actuating unit 482, the first rod piece 483 and the second rod piece 484 being arranged at a distance from each other in the longitudinal direction so as not to interfere with the first rod piece 483 during the movement of the second rod piece 484. Wherein the membrane is allowed to extend between the first rod 483 and the second rod 484 when the second rod 484 is in the first set-up position, as shown herein with reference to figure 53 a. After the membrane extends between the first rod 483 and the second rod 484, the second rod 484 is moved downward to the second priming position to create a folded-bottom structure 95 in the intermediate portion 94, as shown in FIG. 53 b.

Therefore, the shape of the folder 95 is determined by the number of the first rod 483 and the second rod 484. For example, by providing the first rod 483 and the second rod 484 in the number of two and one, respectively (in this case, the second rod 484 is located between the two first rods 483 as viewed in the longitudinal direction), a V-shaped folded bottom structure 95 in which two films are laminated can be obtained. For example, by setting the number of the first bars 483 to one and the number of the second bars 484 to two, with the first bars 483 being positioned between the two second bars 484, the folded bottom structure 95 in which the 4-layer films 91 are laminated in a W-shape can be obtained. Alternatively, two second bars 484 may be provided aligned in the longitudinal direction at all times and at the same distance from the first bars 483, so that the resulting folded-bottom structure 95 is evenly stressed in use.

In addition, bottom building mechanism 48 may include a second bottom building actuating unit, and two second levers 484 may be movable relative to the bottom building support in the longitudinal direction toward or away from each other to switch between a bottom building clamping position (shown with reference to fig. 53 c) in which the longitudinal distance between two second levers 484 is smaller than the longitudinal distance between two second levers 484 in the second bottom building position, and a second bottom building position, driven by the second bottom building actuating unit. By this clamping action, the folded-bottom structure 95 can be brought into a relatively flat configuration, thereby reducing the chance of wrinkles occurring during the subsequent bag edge sealing process.

Wherein the second bottoming actuating unit may be configured in any suitable manner. Alternatively, as shown with reference to fig. 49, 50 and 52, the second bottoming actuating unit includes a sliding cylinder 485 and a rod support 486, the sliding cylinder 485 having two sliders 4851, each second rod 484 being fixed to a respective slider 4851 by a respective rod support 486. First bottoming actuation unit 482 may also be configured in any suitable manner. Alternatively, the first building actuating unit 482 is configured as a linear cylinder, and a cylinder body of the sliding cylinder 485 is fixedly mounted to a piston rod of the first building actuating unit 482.

In addition, the first rod 483 may be constructed as a hollow rod, and the outer end is used to communicate with an external blowing gas source. Under the condition that an external blowing air source is connected, the blowing air of the corresponding first rod pieces 483 at the left end and the right end of the film 91 towards each other can smooth the film part between the first rod pieces 483 at the two sides, so that the flatness of the folded bottom structure 95 is improved or ensured.

In embodiments provided by the third aspect of the present disclosure, the footing bracket may be configured in any suitable manner. Alternatively, as shown in fig. 49 and 52, the bottom-building support includes a bottom-building mounting plate 4811 and a bottom-building pillar 4812, the bottom-building mounting plate 4811 is configured in an L-shape and has a first side portion and a second side portion angled to each other, a first bottom-building actuating unit 482 is mounted to the first side portion, the bottom-building pillar 4812 is fixedly mounted to the second side portion, a first rod 483 is mounted to an end of the bottom-building pillar 4812 remote from the second side portion, and the first rod 483 is communicated with an external blowing air source through the end. Accordingly, the bottom-building mounting plate 4811, which is a construction suitable for mounting both the first rod 483 and the first bottom-building actuating unit 482, can save the number of parts to some extent.

In addition, in some embodiments provided by the third aspect of the present disclosure, the first rod 483 and the second rod 484 may each be configured in a circular rod shape to provide surface contact when in contact with the film 91. Furthermore, the second lever 484 may be provided coaxially with a rolling sleeve, and if the membrane 91 is moved relative to the second lever 484 in contact with the membrane 91, the friction between the two is in the form of rolling friction, which reduces the pulling of the membrane 91. In addition, in other embodiments provided in the third aspect of the present disclosure, as shown in fig. 52, the second lever 484 may be configured in a semicircular rod shape to increase the area of the second lever 484 in contact with the film 91, thereby improving the flatness of the folded-bottom structure 95.

In the embodiment provided by the third aspect of the present disclosure, the building mechanism 48 may include a third building actuating unit 487, and the building support is movably disposed on the moving platform 200 so as to be capable of moving in the vertical direction relative to the moving platform 200 under the driving of the third building actuating unit 487. Considering that the flap structure 95 is located in the middle portion 94 of the film and the middle portion 94 is located below the outer article 1, it is possible to make the flap structure 95 not bear the pressure of the outer article 1 in view of the flatness. In this regard, a downwardly concave groove may be designed in the bearing plane provided on the mobile platform 200, and the first rod 483 and the second rod 484 are vertically lower than the bearing plane by the driving of the third bottoming actuating unit 487, and the bottom-folding structure 95 is hidden in the groove, so that the bottom-folding structure 95 is no longer pressed by the articles 1, which is beneficial to maintain the flatness of the entire middle portion 94, i.e., the bottom of the bag. It should be noted that, when the first conveying mechanism 51 is disposed on the movable platform 200, since the first conveying mechanism 51 provides a bearing plane for the outer article 1, the groove should be defined by the first conveying mechanism 51. For example, when a crawler conveyor is used as the first conveyor 51, two crawler conveyors need to be provided on the moving platform 200, and the gap between the two crawler conveyors serves as the above-described groove, as shown with reference to fig. 26 and fig. 53a to 53 f.

The flatness of the fold-down structure 95 is thus further facilitated in combination with the above-described clamping action of the second lever 484 and the pressure design, where the entire bottoming mechanism 48 is moved downward relative to the mobile platform 200 such that the fold-down structure 95 avoids the carry-over article 1.

In addition, the third bottoming actuating unit 487 may be configured as a linear cylinder, a piston rod of the third bottoming actuating unit 487 is fixedly connected to the bottoming bracket, and a cylinder body thereof may be fixedly connected to the moving platform 200. Therefore, the whole bottom building mechanism 48 can be disassembled by disassembling and assembling the cylinder body of the third bottom building actuating unit 487, so that the maintenance and repair are convenient, and the new or iteratively upgraded bottom building mechanism 48 is more convenient to replace.

Here, it should be understood that, in order to avoid the mutual interference of the movements during the operations of the respective mechanisms, the bottom-building mechanism 48 is located outside the bag-side pressing mechanism 44 and the bag-side pressing mechanism 44 is located outside the bag-side heat-sealing mechanism 41 in the lateral direction for either of the left and right sides of the film 91. In which the bottom-building mechanism 48 is located outside the end of the groove provided on the moving platform 200, as shown in fig. 26.

The packing process will be described in detail below with reference to fig. 53a to 53f based on the above description:

the movable platform 200 is moved to a predetermined position (for example, the first position or the third position described above), and the film 91 is pulled forward across the movable platform 200 by the film pulling mechanism 33, during which the left and right sides of the film 91 pass between the first rod 483 and the second rod 484 located at the first building position, as shown in fig. 53a, wherein the holding point K on the left side of the drawing can be regarded as the film pulling mechanism 33.

Thereafter, second bar 484 is moved down to the second bottoming position, creating a folded structure 95 in intermediate portion 94 of membrane 91, as shown in FIG. 53 b. Then, the second lever 484 is moved to the bottom clamping position, as shown in fig. 53 c.

Thereafter, the mobile platform 200 moves up to the first position (for example, the initial position is the third position), the hatch 1005 is opened, and the user stacks the brought-in article 1 on the film 91 laid on the mobile platform 200 through the input port 1001, as shown in fig. 53 d.

Thereafter, the movable platform 200 moves downward, the film 91 is pulled downward by the bottom-building mechanism 48, and the film-pulling mechanism 33 is held by the film-pulling mechanism 33 based on the front end edge of the film 91, and the film-pulling mechanism 33 is relatively fixed in the vertical direction, so that the film-pulling mechanism 33 moves back, and the front end portion 92 of the film 91 is folded upward in accordance with the downward movement of the movable platform 200. And for the rear end of the film 91, the film feeding mechanism 32 holds and continuously feeds the film. Thus, in conjunction with the downward movement of the movable platform 200, the rear end portion 93 of the film 91 is also folded upward, as shown in fig. 53 e.

During the downward movement of the moving platform 200, in the first embodiment, the rear portion 93 changes the extending direction downward after passing the first bag press wheel 4511, and the front portion 92 changes the extending direction downward after passing the second bag press wheel 4512, and thus the front portion 92 and the rear portion 93 are maintained close to each other by the support of the first bag press wheel 4511 and the second bag press wheel 4512. When the moving platform 200 moves down by a preset value, the first and second

hem actuating units

443, 444 of the bag hem pressing mechanism 44 drive the first and second

pressing blocks

441, 442 to approach each other, pressing the film portions therebetween to each other. At this time, in the first embodiment, the film cutting mechanism 34 cuts the film 91 at the rear end, thereby obtaining a film having a predetermined length, and the rear end portion 93 of the film will continue to be held by the guide fixed wheel set 3410 and the guide floating wheel set 3411.
