Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of exemplary embodiments of the present application is provided in conjunction with the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application and not exhaustive of all embodiments. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.

Example 1

The carton processing machine provided by the embodiment of the application can be suitable for continuously folding paperboards and common paperboards, and the continuous folding paperboards are more used. As shown in fig. 1A, the carton processing machine comprises a paperboard bin 1, a paper changer 2 and a carton forming machine 3, wherein the paper changer 2 and the carton forming machine 3 are arranged at intervals.

As shown in fig. 3A, the paper changer 2 is configured to vertically and hierarchically hold multiple kinds of paper boards 41, and further configured to drive the paper boards 41 to move up and down in a vertical direction, and drive the selected paper boards to enter the box making machine 3 after the selected paper boards move to a preset height; the carton forming machine 3 is used for processing paperboards to form cartons, and the processing comprises cutting, transverse slotting, transverse line pressing, longitudinal line pressing and longitudinal slitting.

The paper changer clamps paperboards with various widths in a layered mode in the vertical direction, and can drive all paperboards to move up and down in the vertical direction, so that the selected paperboards can move to a preset height. Therefore, the paper board with the highest utilization rate can be selected from paper boards with various widths according to the size of the paper box, namely the selected paper board is used, so that the cut part of the selected paper board is smaller, and the waste of the paper board is less. Then, the paper changer drives the selected paper board to enter the box making machine; the carton making machine cuts, transversely slots, transversely presses lines, longitudinally presses lines and longitudinally cuts the paperboards to form cartons.

The selected paper board enters the box making machine from the front end of the box making machine, and is fed from front to back in the box making machine, transversely cut, transversely grooved and pressed, longitudinally slit and pressed and the like to form the paper box. The cartons are fed to eject the paper, carton 42. As shown in fig. 1B and 1C, a transverse cut line 425, a transverse slot 421, a transverse press line 422, a longitudinal press line 424, and a longitudinal parting line 423. As shown in fig. 2A, 2B, 2C and 2D, the box making machine 3 includes a longitudinal slitting and pressing module 30 for performing longitudinal slitting and pressing, where the longitudinal slitting and pressing module 30 includes a longitudinal cutter 31, and the longitudinal cutter is a cutter integrating the longitudinal slitting and pressing.

The structure of the longitudinal cutter of the longitudinal slitting and pressing module is described below.

In practice, as shown in fig. 2E, 2F, 2G and 2H, the longitudinal tool 31 comprises:

longitudinal tool mount 311-1;

the longitudinal wire pressing wheel 312-1 and the cutter mounting arm 313-11 are arranged at the bottom of the longitudinal cutter mounting seat 311-1 at intervals front and back; wherein the longitudinal pressing wheel 312-1 is used for pressing the paper board to form a longitudinal pressing line 424;

a cutter transmission assembly 314 coupled to a lower portion of the cutter mounting arm 313-11, the cutter transmission assembly 314 being disposed obliquely rearward and downward from the lower portion of the cutter mounting arm 313-11;

a longitudinal slitting knife 315-11 connected to the lower end of the knife driving assembly 314, wherein the longitudinal slitting knife is used for longitudinally slitting the cardboard to form a longitudinal slitting line 423;

wherein the bottom surface of the cutter transmission assembly 314 is a lower guiding bottom surface 314-1 inclined downwards from front to back, and the lower guiding bottom surface 314-1 is used for guiding the moving cardboard with the back warp of the pressing line to move below the longitudinal parting cutter 315-11 along the lower guiding bottom surface 314-1.

The lower guide bottom surface 314-1 is inclined downward from front to back, i.e., the paper feed side is higher and the paper exit side is lower. When the paper board comes over, the paper board can be prevented from being blocked due to warping and the like; the cardboard of the rocker can also be guided along the lower guiding bottom surface 314-1. The longitudinal wire pressing wheel 312-1, the cutter mounting arm 313-11 and the longitudinal parting cutter 315-11 are sequentially connected below the longitudinal cutter mounting seat from front to back. During the forward-backward movement of the cardboard, the cardboard is pressed by the longitudinal pressing wheel 312-1, and after the cardboard is pressed, the right end of the cardboard will be warped in fig. 2C, and the warped end of the cardboard is propped against the lower guiding bottom surface 314-1. As the lower guide bottom surface of the cutter drive assembly is inclined downwardly from front to back, the seesaw of the cardboard is pushed down from front to back and moved under the longitudinal slitting cutter 315-11 for longitudinal slitting. Thus, the paper jam phenomenon between the longitudinal line pressing wheel and the longitudinal dividing knife is greatly reduced.

In practice, as shown in FIG. 2C, the direction of rotation of the longitudinal split blade 315-11 is such that the direction of conveyance of the lower edge of the longitudinal split blade coincides with the direction of conveyance of the sheet 41 to guide the sheet 41 to move under the longitudinal split blade 315-11.

The longitudinal slitting knife can realize longitudinal slitting of the paper board in the clockwise or anticlockwise direction. However, when the paper board is just contacted with the longitudinal slitting knife, if the conveying direction of the lower edge of the longitudinal slitting knife is consistent with the conveying direction of the paper board from front to back, the longitudinal slitting knife can play a role of guiding the paper board to move at the same time of longitudinal slitting. That is, as shown in fig. 2C, the longitudinal split knife 315-11 rotates counterclockwise in this view, and also has an effect of preventing the jam of the paper sheet 41, ensuring the smooth passage of the paper sheet.

Specifically, as shown in fig. 2C, when the longitudinal slitting knife 315-11 is in the longitudinal slitting operation position, the range of the angle of inclination of the lower guiding bottom surface from front to back is greater than or equal to 5 degrees and less than or equal to 25 degrees.

The longitudinal slitting knife has an initial position and a longitudinal slitting operating position. When the longitudinal slitting knife is at the initial position, the longitudinal slitting knife is in a lifted state, and the longitudinal slitting knife does not slit the paper board longitudinally. When the longitudinal slitting knife is positioned at the longitudinal slitting working position, the longitudinal slitting knife is in a pressed state, and the longitudinal slitting knife can longitudinally slit the paper board.

In practice, as shown in fig. 2B and 2C, the box making machine further includes a second paper feeding module 322, where the longitudinal slitting knife 315-11 is disposed at intervals with the sun gear 323-13 of the second paper feeding module 322; the sun gear of the second paper feeding module is used for feeding paper to the longitudinally slit paper board to output paper.

Specifically, as shown in fig. 2B and 2C, a gap between the longitudinal cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 is less than or equal to 20 cm; or the clearance between the longitudinal split cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 is greater than or equal to 1 mm and less than or equal to 200 mm.

As shown in fig. 2C, the gap between the longitudinal cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 is smaller than the gap 315-13 after the longitudinal cutter 315-11, and when the paper board 41 is warped less after passing through the longitudinal cutter 315-11, the paper board is pressed by the sun gear 323-13 of the second paper feeding module 322, so that the paper board cannot be warped upwards continuously, and the probability of jamming between the longitudinal wind cutter and the sun gear of the second paper feeding module is smaller.

In practice, as shown in fig. 2E and 2G, the longitudinal tool further comprises:

a longitudinal wire pressing wheel cylinder 312-2 fixed at the bottom of the longitudinal cutter mounting seat 311-1;

A wire pressing cylinder connecting plate 312-3 fixed at the end of the piston rod of the longitudinal wire pressing wheel cylinder 312-2;

the wire pressing wheel mounting seat 312-41 is fixed at the bottom of the wire pressing cylinder connecting plate 312-3, and the longitudinal wire pressing wheel 312-1 is rotatably connected at the wire pressing wheel mounting seat 312-41.

The wire pressing cylinder connecting plate and the wire pressing wheel mounting seat are fixed into a whole, the longitudinal wire pressing wheel 312-1 is rotatably connected to the wire pressing wheel mounting seat 312-41, and the wire pressing cylinder connecting plate is fixed to the end portion of a piston rod of the longitudinal wire pressing wheel cylinder 312-2. In this way, the piston rod of the longitudinal crimping wheel cylinder 312-2 can extend downwardly and reset relative to the longitudinal tool mount. When the longitudinal line pressing wheel is needed to press the paper board longitudinally, the longitudinal line pressing wheel extends downwards to press the paper board longitudinally. The longitudinal line pressing wheel resets downwards when the paper board does not need to be longitudinally pressed. Thus, through a simple structure, the downward extension and the resetting of the longitudinal wire pressing wheel are realized.

In practice, as shown in FIG. 2G, the cutter drive assembly includes a cutter mounting shaft 314-33, and sequentially engaged longitudinal cutter drive gears 314-21, longitudinal cutter transition gears 314-22, and longitudinal cutter driven gears 314-23; the longitudinal cutter driving gear 314-21 is connected to the lower part of the cutter mounting arm 313-11, and the cutter mounting shaft 314-33 is fixed to the longitudinal cutter driven gear 314-23;

The longitudinal split blade 315-11 is detachably connected to the blade mounting shaft 314-33.

The transmission structure of the longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23, which are meshed. The longitudinal cutter driving gear is a power input gear, the longitudinal cutter driven gear is a power output gear, and the longitudinal cutter is driven by the cutter driven gear and the cutter mounting shaft to rotate, so that the longitudinal cutter driving gear drives the cutter mounting shaft and the longitudinal cutter 315-11 to rotate. The three gears are meshed with the transmission structure, so that the structure is compact, the synchronism is good, and the longitudinal slitting knife can automatically rotate. The longitudinal slitting knife can rotate autonomously, the rotation speed of the longitudinal slitting knife is high, and the linear speed of the edge of the longitudinal slitting knife is far greater than the advancing speed of the paper board. The lower part of the longitudinal slitting knife is provided with a longitudinal slitting knife comb which is matched with each other, and the paper board passes through the longitudinal slitting knife comb and the longitudinal slitting knife. The longitudinal slitting knife comb is provided with uniformly distributed comb teeth like a comb, the upper edges of the comb teeth are arc-shaped, and the comb teeth are formed by processing elastic materials. When the paper board needs to be cut longitudinally, the longitudinal slitting knife falls down, the blade of the longitudinal slitting knife falls into the comb slot of the longitudinal slitting knife comb to completely slit the paper board, and the comb teeth of the longitudinal slitting knife comb provide good support for the paper board, so that the paper board is not deformed when being subjected to cutting force.

In operation, as shown in FIGS. 2E and 2G, the cutter drive assembly further includes cutter gearboxes 314-41 and cutter gear box covers 314-42, which form cutter gear mounting boxes;

the longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 are obliquely arranged in the gear mounting box from front to back and downwards from the lower part of the cutter mounting arm 313-11;

wherein, the bottom surface of the cutter gear box cover is a lower guiding bottom surface 314-1 which is inclined downwards from front to back.

Thus, the longitudinal cutter transfer gear 314-21, the longitudinal cutter transition gear 314-22, and the longitudinal cutter driven gear 314-23 are disposed in the gear mounting case.

The three gears are arranged in the gear mounting box, so that scraps possibly generated when the paper board is processed are isolated outside the gear mounting box, and the influence on the gears is reduced; meanwhile, the gear can be effectively lubricated.

In the implementation, the shell is provided with three through holes, the cutter gearbox ball bearings are fixed in the through holes, and the cutter gear box cover is provided with the through holes, and the cutter gear box cover ball bearings are fixed in the through holes;

as shown in fig. 2G, the cutter transmission assembly further includes:

A transmission gear positioning shaft 314-31 fixed with the shaft hole of the longitudinal cutter transmission gear 314-21;

a transition gear mounting shaft 314-32 fixed to the shaft hole of the longitudinal cutter transition gear 314-22;

wherein the transmission gear positioning shaft 314-31, the transition gear mounting shaft 314-32 and the cutter mounting shaft 314-33 are respectively fixed on the inner rings of the cutter gearbox ball bearing and the cutter gearbox cover ball bearing.

The transmission gear positioning shaft 314-31 and the longitudinal cutter transmission gear 314-21 are fixed into a whole, the transmission gear positioning shaft 314-31 is connected with a cutter gear box ball bearing and a cutter gear box cover ball bearing of the shell of the cutter gear box, and the transmission gear positioning shaft 314-31 and the longitudinal cutter transmission gear 314-21 can rotate in a gear mounting box. Similarly, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 can rotate within the gear mounting box.

The cutter gear mounting case formed by the cutter gear case housing 314-41 and the cutter gear case cover 314-42, the cutter mounting arm 313-11 are mounted through bearings and the transmission gear positioning shaft 314-31, i.e., the cutter transmission assembly as a whole can rotate about the transmission gear positioning shaft 314-31.

In practice, as shown in fig. 2A, 2D, 2E and 2G, the longitudinal split pressing line module further includes:

the longitudinal cutter transmission shaft 316-11 is fixedly connected with a through hole shaft hole reserved in the center of the transmission gear positioning shaft 314-31;

externally meshed longitudinal cutter driven gear 316-12 and longitudinal cutter driving gear 316-13 such that the directions of rotation of the longitudinal cutter driven gear and longitudinal cutter driving gear 316-13 are opposite;

wherein the longitudinal cutter driven gear 316-12 is fixed at the end of the longitudinal cutter transmission shaft 316-11, and the longitudinal cutter driving gear 316-13 and the second paper feeding driving gear are connected by a second driving synchronous belt mechanism;

the box making machine is provided with a second paper feeding motor positioned below the paperboard position, and an output shaft of the second paper feeding motor is connected with a second driving synchronous belt mechanism in a matched mode.

The rotation directions of the longitudinal cutter driven gear 316-12, the longitudinal cutter driving shaft 316-11 and the longitudinal cutter driving gear 314-21 are the same; the longitudinal cutter driving gear 314-21 and the longitudinal cutter driven gear 314-23 are rotated in the same direction. The rotation directions of the longitudinal cutter driven gear 314-23 and the longitudinal cutter driving gear 316-13 are opposite, i.e., the rotation directions of the longitudinal cutter driven gear 314-23 and the output shaft of the second paper feeding motor are opposite. The longitudinal cutter driven gear 314-23 is positioned above the paper board to rotate, and the second paper feeding motor rotates below the paper board to feed paper, so that the rotation directions of the longitudinal cutter driven gear 314-23 and the second paper feeding motor are opposite, but the conveying direction of the lower edge of the longitudinal cutter is consistent with the conveying direction of the second paper feeding motor to the paper board.

Specifically, the longitudinal cutter driving shaft 316-11 is designed as a hexagonal shaft, and the through hole reserved in the center of the driving gear positioning shaft 314-31 is a hexagonal hole, so that the longitudinal cutter driving shaft 316-11 is fixedly connected with the through hole shaft hole reserved in the center of the driving gear positioning shaft 314-31. Thus, power is transmitted from the second paper feed motor to the longitudinal cutter drive shaft 316-11 and then to the longitudinal cutter 315-11, so that the longitudinal cutter 315-11 is powered.

In practice, as shown in fig. 2F, 2G and 2H, the cutter mounting shaft 314-33 of the cutter transmission assembly penetrates through the housing formed by the cutter gear box and the cutter gear box cover, and symmetrically extends out of two sides of the housing formed by the cutter gear box and the cutter gear box cover;

the longitudinal split blades 315-11 can be detachably mounted at both ends of the blade mounting shaft 314-33.

Thus, the longitudinal split blades 315-11 may be individually mounted at either end of the blade mounting shaft 314-33, and two longitudinal split blades 315-11 may be mounted at both ends of the blade mounting shaft 314-33, respectively. So that the installation of the longitudinal split blade 315-11 is made possible in a variety of ways and can be applied in a variety of situations.

In practice, as shown in fig. 2F, 2G and 2H, the cutter transmission assembly is a symmetrical structure with the center line of the cutter mounting shafts 314-33 as the symmetry axis; the longitudinal cutter further comprises a wire pressing wheel mounting shaft 312-42 which penetrates through the wire pressing wheel mounting seat and symmetrically extends out, and the longitudinal wire pressing wheel 312-1 can be detachably mounted at any one end and/or two ends of the wire pressing wheel mounting shaft 312-42;

The longitudinal cutter is at least two, and each longitudinal cutter is coaxially arranged on the longitudinal cutter transmission shaft, and the longitudinal slitting cutters of two adjacent longitudinal cutters can be arranged on one opposite side so that the two longitudinal slitting cutters are adjacently arranged, and the longitudinal wire pressing wheels of two adjacent longitudinal cutters can be arranged on one opposite side so that the two longitudinal wire pressing wheels are adjacently arranged.

The longitudinal cutter has symmetrical structure, and the longitudinal wire pressing wheel and the longitudinal slitting knife can be installed on both sides, so that the longitudinal wire pressing wheel and the longitudinal slitting knife can be selectively installed according to the processing requirement. The design enables the device to process ultrathin cartons, namely when the longitudinal wire pressing wheels and the longitudinal slitting knives are installed in opposite directions, the longitudinal wire pressing wheels of two adjacent longitudinal knives can be close together, and the longitudinal slitting knives of two adjacent longitudinal knives can be close together.

When there are a plurality of longitudinal cutters, the longitudinal cutters of each longitudinal cutter can be arranged on the same side of the cutter transmission assembly, and at the moment, the distance between the longitudinal cutters is the minimum thickness of the cutter transmission assembly. The longitudinal slitting knives of the two adjacent longitudinal knives can be arranged on the opposite sides so that the two longitudinal slitting knives are arranged adjacently, and at the moment, the distance between the two longitudinal slitting knives breaks through the thickness of the slitting transmission assembly. Therefore, the longitudinal slitting knife 315-11 can be detachably mounted at two ends of the knife mounting shaft 314-33, so that the distance between the longitudinal slits of the carton processing machine is more likely, and the carton processing machine has stronger universality.

As shown in fig. 1B and 1C, a transverse cut line 425, a transverse slot 421, a transverse press line 422, a longitudinal press line 424, and a longitudinal parting line 423. The thickness of the carton is determined by the distance between two longitudinal parting lines 423 and the distance between two longitudinal parting lines 423 is determined by the distance between the longitudinal parting lines 315-11 of two adjacent longitudinal parting lines. The manner in which the longitudinal parting blades 315-11 of two adjacent longitudinal tools can be disposed adjacently not only can process cartons having a large thickness, but also can process cartons having a small thickness. The thickness of the paper box is the minimum distance between the longitudinal cutting knives of the two adjacent and closely attached longitudinal cutting knives.

In practice, as shown in fig. 2F, the longitudinal tool further comprises:

the wire pressing wheel ball bearings are reserved in the longitudinal wire pressing wheel 312-1, the wire pressing wheel ball bearings are fixed in the through holes, and the wire pressing wheel mounting shaft 312-42 is detachably fixed to the inner ring of the wire pressing wheel ball bearings, so that the longitudinal wire pressing wheel 312-1 can rotate by taking the wire pressing wheel mounting shaft 312-42 as the center.

In the implementation, the longitudinal line pressing wheel and the longitudinal slitting knife which are arranged on the same side of the longitudinal knife are positioned on the same straight line.

Therefore, the paper board is longitudinally pressed by the longitudinal pressing wheel, and then is longitudinally cut at the position of the longitudinal pressing wheel.

In practice, as shown in fig. 2E, 2F and 2G, the longitudinal tool further comprises:

the longitudinal cutter splitting cylinder 315-12, the cutter mounting arm 313-11 and the longitudinal cutter splitting cylinder 315-12 are fixed at the bottom of the longitudinal cutter mounting seat 311-1 at intervals from front to back, and a piston rod of the longitudinal cutter splitting cylinder 315-12 is fixed with the cutter transmission assembly 314 to drive the longitudinal cutter splitting cylinder 315-11 to move downwards and reset upwards;

As the cutter drive assembly as a whole is able to rotate about the drive gear positioning shaft 314-31. The longitudinal cutter cylinder 315-12 controls the rotation of the cutter driving assembly, thereby controlling the lifting of the longitudinal cutter and completing the longitudinal cutting action of the paperboard.

The longitudinal cutter mounting seat 311-1 is provided with the longitudinal cutter mounting seat wire passing hole 311-21, so that the air inlet pipe and the air outlet pipe of the longitudinal cutter splitting cylinder 315-12 can conveniently pass through the longitudinal cutter mounting seat wire passing hole 311-21 to be connected with an external air source. Thus, the space of the longitudinal cutter mounting seat 311-1 is fully utilized, so that the integral wiring of the air inlet pipe and the air outlet pipe of the longitudinal cutter is simpler.

In practice, as shown in fig. 2E, 2F and 2G, the longitudinal wire pressing wheel cylinder 312-2 is fixed at the bottom of the longitudinal tool mounting seat 311-1 and is located in front of the cutter mounting arm 313-11;
