Description

Technical Field

The invention relates to the technical field of glove manufacturing, in particular to a semi-dipped glove production line and a semi-dipped glove dipping method.

Background

The glove is divided into a full-dipped glove and a half-dipped glove. The fully impregnated glove is prepared by impregnating the palm and the back of the hand to the wrist. The semi-impregnated glove is impregnated by palm, and the back of the hand is not impregnated to be breathable.

The hand mould mounting modes of the full-impregnated glove and the half-impregnated glove are completely different in production. The hand mould of the full-impregnated glove is in a suspension state that fingertips face to the right lower side at the impregnation station, so that the palm and the back of the hand can be immersed into the glue pool, meanwhile, the conveying chain on the production line of the full-impregnated glove is single, and the hand mould is suspended at intervals along the extending direction of the conveying chain. The hand mould of half gum dipping gloves is the palm state down at the gum dipping station, and then the palm is immersed in the liquid level in the gum dipping pond in the back of the hand deviating from the gum dipping pond, simultaneously, the production line of half gum dipping gloves includes two spaced chains, two with two chain sprocket groups of chain one-to-one meshing in order to guide two chain synchronous motion, connect the hand mould pole between two chain, hang in at least one hand mould on the hand mould pole, the hand mould orientation is that the palm is outwards and the back of the hand is inwards (just the palm is downwards and the back of the hand is upwards when moving to the gum dipping station).

In the conventional gum dipping process of the semi-gum dipping glove, a lot of gum is taken away when the glove is separated from the gum solution due to the large palm area of the glove, so that the conventional gum dipping step is required to be followed by the gum dipping and gum homogenizing steps. In this regard, the chinese patent application No. CN113427689a discloses that a guide member is provided on the frame to guide the chain, so that the hand mold gradually leaves the dipping box with a constant height in a laterally inclined arrangement manner, and a proper amount of glue solution is left on the glove by using the surface tension of the glue solution, without performing a glue dropping operation. Although CN113427689a implements omitting the step of glue dripping, it requires a larger production space to set the guide member, and the glove has a longer glue entering path and a longer glue exiting path, requiring a longer glue dipping tank, more glue storage, and higher production cost.

Detailed Description

The invention will be better explained by the following detailed description of the embodiments with reference to the drawings.

Example 1

Referring to fig. 1 to 6, the present embodiment provides a semi-dipped glove production line. The semi-dipped glove production line comprises a semi-dipped glove hand mould conveying mechanism and a liftable glue pool 2.

The semi-dipped glove hand mould conveying mechanism comprises a frame 1, two spaced chains 3, two chain wheel groups, a plurality of hand mould rods 5 and a plurality of hand moulds 4, glove blanks to be processed are sleeved on the hand moulds 4, and the hand moulds 4 are subjected to glue feeding, glue discharging and glue dipping, and are equivalent to the glove blanks on the hand moulds.

Specifically, two sprocket sets are arranged in one-to-one correspondence with two chains 3, and each chain 3 is meshed with the corresponding sprocket set to obtain supporting and walking power. The sprockets of the two sprocket sets are symmetrically arranged to guide the two chains 3 to move in synchronization, and when the sprocket arrangement is described in detail below, only the sprocket of one set is described, but the same applies to the other set. The chain wheels in the chain wheel group are rotatably supported on the frame 1. A plurality of hand mold rods 5 are connected between the two chains 3, and the hand mold rods 5 are generally arranged perpendicular to the chains 3. At least one hand die 4 is suspended on each hand die bar 5 (at least two hand dies 4 are arranged at regular intervals in the extending direction of the hand die bar 5 to improve the production efficiency), and the arrangement direction of the wrist portions and the finger portions of the hand dies 4 is the direction from downstream to upstream in the moving direction of the chain 3, i.e., the wrist portions of the hand dies 4 are located on the downstream side with respect to the finger portions; the hand mould 4 is oriented with the palm facing outwards and the back facing inwards, wherein the term "outer" and "inner" as used herein refers to the area divided by the chain 3, and the side of the device for processing the glove blanks on the hand mould 4, such as the liftable glue pond 2, is the "outer" and the opposite "inner". Meanwhile, the hand mold rod 5, the hand mold 4 on the hand mold rod 5 and the chain plate on the chain 3 connected with the hand mold rod 5 are fixed in relative positions and orientations, namely, the orientations of the chain plates determine the orientations of the hand mold rod 5, the orientations of the hand mold rod 5 determine the orientations of the hand mold 4 on the hand mold rod, the orientations of the chain plates are changed, and the orientations of the hand mold rod 5 and the hand mold 4 are also changed in the same direction and the same amount.

Specifically, the sprocket group includes, in the traveling direction of the chain 3, a dipping sprocket 6 located above the liftable vat 2, an upstream sprocket (not shown in the figure) located upstream of the dipping sprocket 6, and a downstream sprocket (not shown in the figure) located downstream of the dipping sprocket 6 in this order. It will be appreciated that the two impregnated sprockets 6 of the two sprocket sets are symmetrically arranged with the axis coincident, the two upstream sprockets of the two sprocket sets are symmetrically arranged with the axis coincident, and the two downstream sprockets of the two sprocket sets are symmetrically arranged with the axis coincident.

The liftable glue pond 3 and sprocket set cooperation are set up as:

the positions of the upstream sprocket and the impregnation sprocket 6 determine the orientation of the link plates in the chain 3 upstream of the impregnation sprocket 6 and thus the orientation of the hand mold bars 5 and the hand molds 4 upstream of the impregnation sprocket 6. In the present embodiment, the upstream sprocket and the dipping sprocket 6 guide the hand die 4 located upstream of the dipping sprocket 6 to travel from the upstream sprocket to the dipping sprocket 6 at a preset dipping angle by guiding the orientation of the link plate located upstream of the dipping sprocket 6 in the chain 3. The upstream sprocket and the dipping sprocket 6 guide the hand mold 4 located upstream of the dipping sprocket 6, and the orientation of the palm downward and the upstream direction of the joint of the hand mold 4 and the hand mold rod is a preset glue inlet angle, that is, when the hand mold 4 contacts with the liquid level, the palm downward and the fingertip of the hand mold 4 are located in the upstream direction of the joint of the hand mold 4 and the hand mold rod.

When the upstream sprocket and the impregnation sprocket 6 guide the hand pattern upstream of the impregnation sprocket 6 to the first position, the hand pattern is regarded as a target impregnation hand pattern 4' immediately before the impregnation starts. At this time, the liftable glue pool starts to rise. The upstream sprocket and the dipping sprocket 6 further guide the target dipping hand die 4 'to contact the liquid level in the lifting glue pool 2 in the lifting state at a preset glue inlet angle, and further guide the target dipping hand die 4' to walk in the glue solution for dipping. When the target gum dipping hand die moves to the lowest point corresponding to the gum dipping chain wheel 6, the liftable gum pool 2 is positioned at the highest point, and the liftable gum pool 2 starts to descend.

The positions of the downstream sprocket and the impregnation sprocket 6 determine the orientation of the link plates in the chain 3 downstream of the impregnation sprocket 6 and thus the orientation of the hand mold bars 5 and hand molds 4 downstream of the impregnation sprocket 6. In the present embodiment, the downstream sprocket is located above the dipping sprocket 6, and the downstream sprocket and the dipping sprocket 6 guide the chain 3 to be separated from the dipping sprocket 6 at the outer end point of the dipping sprocket 6 by guiding the orientation of the link plate located downstream of the dipping sprocket 6 in the chain 3 so that the link plate away from the dipping sprocket 6 moves upward in a vertical orientation. Further, a drying box is arranged behind the gum dipping station, and the chain wheel group guides the chain 3 to pass through the drying box to dry the gum dipped hand mould.

In this embodiment, the chain 3 is meshed with the impregnation sprocket 6 at about 1/4 circumference of the outer lower portion of the impregnation sprocket 6. The chain plate meshed with the dipping chain wheel 6 is determined by the dipping chain wheel 6, namely the dipping chain wheel 6 guides the chain plate meshed with the chain 3 to move along the peripheral track thereof, in particular the chain plate moves outwards from the lower part of the dipping chain wheel 6 to form upward turning movement, the hand mould 4 corresponding to the section of the meshed chain plate moves upwards along with the upward turning movement, and meanwhile, the finger tip rotates downwards to turn, so that the glue is separated from the liquid level in the lifting glue pool 2 in a descending state at a preset glue outlet angle without glue dripping. The impregnation sprocket 6 guides the hand mold 4 corresponding to the chain plate meshed with the impregnation sprocket in the chain 3, and the orientation of the hand mold 4 in the upstream direction of the joint of the hand mold 4 and the hand mold rod is a preset glue outlet angle, that is, when the hand mold 4 is separated from the liquid level, the hand mold 4 is downward and the fingertip is in the upstream direction of the joint of the hand mold 4 and the hand mold rod.

Based on the above structure, the present embodiment has the following main advantages:

(1) Through the cooperation setting and linkage of liftable glue pond 2 and the sprocket group that includes the single gum dipping sprocket 6 that is located liftable glue pond 2 top, can guide the income of hand mould smoothly and glue, hand mould 4 both march forward, have the angle variation and form palm inclination state again, can separate with the liquid level in the liftable glue pond 2 of the presupposition play glue angle of not dripping and the decline state, make the perfect realization surface tension of gum dipping process peel off the film formation, save vibrations, glue dripping, rotatory homogenate step also makes production line structure simpler, take up an area of littleer.

(2) The glove mold 4 is stripped to form a film through surface tension, meanwhile, the generation of bubbles is reduced, a glove dipping layer with good uniformity and smooth surface is formed, and the product quality and the film forming quality are improved.

(3) The glue discharging posture of the hand mould 4 is adjusted through the peripheral shape of only one glue dipping chain wheel 6, and the structure is simple and the precision is high.

(4) The lifting glue pool 2 is used, and the lifting glue pool 2 is only provided with one glue dipping chain wheel 6 to be matched with the lifting glue pool 2, so that the hand mold 4 is guided to glue from glue inlet to glue outlet, the equipment structure is simpler, the glue inlet stroke and the glue outlet stroke are reduced through the opposite movement and opposite movement of the lifting glue pool and the chain plate, the size of the glue pool can be reduced by at least one third, the glue adding amount is reduced by more than 30% at one time, and the production cost is further reduced. At the same time, the method comprises the steps of,

(5) Only one gum dipping chain wheel 6 is used for replacing the whole guiding component in sliding contact with the chain 3 in the prior art, so that equipment maintenance expenditure caused by bidirectional abrasion of the chain 3 and the guiding component is avoided, and maintenance cost and production cost are reduced; and further reduces the power loss of the chain drive motor, and effectively saves energy.

(6) The semi-dipped glove production line of the embodiment does not need an external rotating mechanism and an external moving mechanism for dipping, is favorable for realizing closed production, realizes centralized collection of certain gases generated in the production process, improves the environmental protection treatment effect and saves a large amount of environmental protection treatment cost.

(7) The movement of the chain 3 is not stopped during gum dipping, which is beneficial to continuous production and improves the production efficiency.

Further, in the present embodiment, both ends of the hand mold bar 5 are fixed to the chain 3 through the connection plates 7. The connecting plate 7 is a straight plate with two fixing locations a fixed with adjacent two rotational locations of the chain 3. Specifically, in this embodiment, two adjacent rotation positions of the chain 3 are two hollow pins 8 connected to two ends of a link plate, and two fixing positions a of the connecting plate 7 are two through holes formed in the connecting plate. The two hollow pin shafts 8 and the two through holes are correspondingly arranged, a bolt is penetrated in the corresponding hollow pin shaft 8 and the through hole, and the bolt and a nut are screwed together to clamp the connecting plate 7 and the chain plate of the chain 3. Therefore, the chain plate rotates, the connecting plate 7 rotates, the hand mold rod 5 rotates, and the hand mold 4 rotates, so that the relative positions and the directional fixed arrangement of the hand mold rod 5, the hand mold 4 on the hand mold rod 5 and the chain plate on the chain 3 connected with the hand mold rod 5 are realized.

Of course, the mode of fixing the relative positions and orientations of the hand mold bar 5, the hand mold 4 on the hand mold bar 5, and the link plate on the chain 3 to which the hand mold bar 5 is connected is not limited to the above-described structure, and any mode is possible to fix the hand mold bar 5 and the chain 3.

In the present embodiment, the connection point of the connection plate 7 with the hand die bar 5 is located in the middle between the two fixing positions a to the center line between the fingertips of the hand die 4 (center line of the connection line along the extending direction of the chain 3). Thereby, space can be saved, more hand mold rods 5 are hung on the chain 3, and production efficiency is improved.

While the angle between the hand mould 4 and the chain 3 is preferably parallel, i.e. the palm surface of the hand mould 4 is parallel to the direction of extension of the chain 3 (allowing for reasonable mounting errors). Therefore, the design of the preset glue inlet angle, the preset glue outlet angle and the positions and the movements of related parts are simpler and more convenient.

In this embodiment, a position sensor is provided on the frame 1, and the position sensor senses whether the hand pattern 4 located upstream of the impregnation sprocket 6 reaches the first position, and when the position sensor senses that the hand pattern 4 located upstream of the impregnation sprocket 6 reaches the first position, a command signal is given to a controller of the production line. The controller controls the lifting glue pool 5 to lift.

The rising speed of the liftable glue pool 5 is related to the distance between the first position and the lowest point of the glue dipping sprocket 6, and the travelling speed of the chain 3, the initial position of the liftable glue pool 2 and the like are also considered, and when the hand mold 4 positioned upstream of the glue dipping sprocket 6 reaches the lowest point of the glue dipping sprocket 6 from the first position through calculation and experiment, the liftable glue pool 2 rises until the hand mold 4 reaches the preset glue dipping depth.

Of course, the present invention is not limited thereto, and when the preset impregnation angle is 0 °, the liftable rubber pool 2 can be lifted to reach the preset impregnation depth by the hand mold 4 located upstream of the impregnation sprocket 6 before the hand mold 4 reaches the lowest point of the impregnation sprocket 6 from the first position, in addition to lifting the liftable rubber pool 2 to reach the preset impregnation depth by the hand mold 4 when the hand mold 4 located upstream of the impregnation sprocket 6 reaches the lowest point of the impregnation sprocket from the first position, so that the impregnation time is increased according to the process requirement, but the size of the liftable rubber pool 2 is increased at the same time. The time for keeping the height of the liftable glue pool 2 unchanged can be set to be a preset time for descending after the controller controls the liftable glue pool to stop ascending, wherein the preset time is determined according to the distance between the position of the target glue dipping hand die 4' when the liftable glue pool 2 stops ascending and the lowest point of the glue dipping chain wheel 6 and the advancing speed of the chain 3; alternatively, a position sensor may be fixed on the frame 1 or the dipping sprocket 6, and when the position sensor senses that the hand mold moves to the lowest end of the dipping sprocket 6, a command signal is given to the controller, and the controller controls the lifting glue pool 2 to descend.

In this embodiment, the upstream sprocket and the impregnation sprocket 6 guide the chain 3 to start to mesh with the impregnation sprocket 6 at the lowest point of the impregnation sprocket 6, that is, guide the link plate between the two to be horizontally oriented, and the hand mold 4 is parallel to the chain 3, so that the preset glue inlet angle is 0 °, that is, the fingertip is horizontally oriented in the upstream direction.

Of course, the invention is not limited thereto, and the angle between the hand mould 4 and the chain 3 may not be parallel, but have a fixed non-zero included angle; the link plates between the upstream sprocket and the impregnation sprocket 6 may also not be oriented horizontally, but rather inclined at an angle according to the impregnation zone requirements of the hand mould 4.

The angle between the hand mould 4 and the chain 3 and the angle of the chain link between the upstream sprocket and the gum dipping sprocket 6 together determine a preset gum entering angle, which is the angle between the palm of the hand mould 4 and the horizontal direction, preferably the preset gum entering angle is in the range of-5 ° to 40 °, wherein the finger is positive downwards relative to the horizontal direction and the finger is negative upwards relative to the horizontal direction.

Further, in this embodiment, a liquid level sensor is disposed on the frame 1, and senses the liquid level in the liftable glue pool 2, when the liquid level in the liftable glue pool 2 reaches the second position, the liftable glue pool 2 is considered to rise to the hand mold 4 to reach the preset glue dipping depth, the liquid level sensor gives an instruction signal to the controller, and the controller controls the liftable glue pool 2 to stop rising, and immediately starts to descend or keeps the height unchanged according to the two schemes. Wherein, the determination of the second position considers the first position, the travelling speed of the chain 3, the initial position of the liftable glue pool 2, the rising speed of the liftable glue pool 2 and the like, and the liquid level in the liftable glue pool 2 is used as the representation of the lowest point of the hand mould 4 reaching the dipping sprocket 6 through calculation and experiment. Of course, the invention is not limited to this, in the scheme that the lifting glue pool 2 starts to descend immediately after stopping lifting, a position sensor can also be directly arranged on the frame 1 or the glue dipping sprocket 6 to sense whether the hand mould reaches the lowest point of the glue dipping sprocket 6, if the position sensor senses that the hand mould reaches the lowest point of the glue dipping sprocket 6, an instruction signal is given to the controller, and the controller controls the lifting glue pool to stop lifting and start descending at the same time.

In the present embodiment, the size of the impregnated sprocket 6 determines the angular velocity of the link plate engaged therewith and thus the angular velocity of the hand mold 4. Preferably, the number of teeth of the dipping sprocket 6 is in the range of 17-70, and the pitch of the dipping sprocket 6 is in the range of 38.1-100 mm, so as to prevent the angle change from being too fast when the hand mold 4 is out of glue, and the dipping quality from being reduced.

The descending speed of the liftable glue pond 2 is related to the rotating speed of the glue dipping chain wheel 6, and the size of the hand mould 4, the travel distance between the lowest point of the glue dipping chain wheel 6 and the separation of the hand mould 4 from the glue dipping chain wheel 6 and the preset glue entering angle of the hand mould 4 are also considered, through calculation and experiments, the non-glue dipping part of the hand mould 4 when the hand mould 4 reaches the lowest point of the glue dipping chain wheel 6 is always positioned above the liquid level of the liftable glue pond 2 when the hand mould 4 rotates at a constant speed with the downward finger tip. In this way, the fingertips of the hand mould 4 are prevented from penetrating deeper into the glue solution and the areas that should not be glued are glued.

Further, the lowering speed of the liftable glue pool 2 is too high, which is not beneficial to forming surface tension without glue dripping when the hand mould 4 is used for glue discharging; the lowering speed of the liftable glue pool 2 is too slow, and a longer glue outlet stroke is needed, so that the size of the liftable glue pool 2 is larger; therefore, the descending speed of the liftable glue pond 2, the travelling speed of the chain 3 and the size of the chain wheel 6 are arranged in a matched manner.

In this embodiment, the preset glue angle is in the range of 20 ° to 90 °. Wherein, the preset glue outlet angle is the included angle between the palm of the hand mould 4 and the horizontal direction, and the positive value of the angle indicates that the fingertip is downward. The preset glue outlet angle is more than or equal to 20 degrees, so that no glue dripping can be well realized. However, if the preset glue outlet angle is larger, the soaking time in the glue pool is longer, namely the running time in the glue pool is longer, and the required glue pool size is larger. Therefore, the preset glue outlet angle is preferably in the range of 20 ° to 80 °, more preferably in the range of 20 ° to 70 °, to further reduce the size of the glue pool on the basis of realizing no glue dripping.

In this embodiment, the liftable glue pond 2 includes support and gluey pond body, glues the pond body and passes through elevation structure support on the support, and actuating mechanism drive glues the pond body and goes up and down along the support. The specific driving mechanism can be an oil cylinder, an air cylinder, a chain sprocket, a rack gear and the like, the lifting structure can be a sliding rail and sliding block structure and the like, and common structures in the prior art are adopted, so that repeated description is omitted.

In this embodiment, the installation distance of the adjacent hand mold bars is set such that the next hand mold is at a predetermined dipping depth when the previous hand mold is separated from the liquid surface by a predetermined glue outlet angle.

In summary, the dipping method of semi-dipped gloves using the semi-dipped glove production line is described as follows:

the chain 3 moves along the sprocket set and the hand mould 4 thereon moves.

The hand die 4 located upstream of the impregnation sprocket 6, after passing the upstream sprocket, proceeds toward the impregnation sprocket 6 at a preset impregnation angle. From fig. 3 to 4, when the position sensor senses that the hand pattern 4 located upstream of the dipping sprocket 6 reaches the first position, the position sensor sends a command signal to the controller, and the controller controls the lifting glue pool 2 to start lifting, and the hand pattern 4 reaching the first position serves as a target dipping hand pattern 4'.

In the state of fig. 4, the target gum dipping hand mold 4' contacts the liquid level in the lifting gum pool 2 in the lifting state at a preset gum entering angle; from fig. 4 to 5, as the liftable glue pond 2 rises, the dipping depth of the target dipping hand mold 4' becomes deep.

In the state of fig. 5, the liquid level sensor senses that the liquid level of the liftable glue pond 2 reaches the second position, and the liquid level sensor sends a command signal to the controller, at this time, the target glue dipping hand die 4 'moves to the lowest point of the corresponding glue dipping sprocket 6 or before the lowest point, and the target glue dipping hand die 4' reaches the preset glue dipping depth. And after receiving the instruction signal, the controller controls the lifting glue pool 2 to stop lifting, and the lifting glue pool 2 reaches the highest point. In this way, the controller controls the liftable glue pool 2 to descend immediately when the target glue dipping hand die 4' is at the lowest point of the glue dipping chain wheel 6; if the target gum dipping hand die 4 'is in front of the lowest point of the gum dipping chain wheel 6, the controller controls the liftable gum pool 2 to descend after a certain preset time, or senses whether the target gum dipping hand die 4' arrives at the lowest point of the gum dipping chain wheel 6, and the position sensor sends instruction signals to the controller when the hand die arrives, and the controller controls the liftable gum pool 2 to descend.

Referring to fig. 5 to 8, the chain segment of the chain 3 corresponding to the target impregnation die 4 'is turned upward along the impregnation sprocket 6, and the target impregnation die 4' is turned at a constant speed with the downward rotation of the fingertip. In fig. 8, the angle of the target dipping hand mold 4 'is changed to a preset dispensing angle, and the target dipping hand mold 4' is separated from the liquid surface in the liftable glue pool 2 in the lowered state. Wherein, the descending speed of the liftable glue pond 2 is related to the rotating speed of the glue dipping chain wheel 6, so that the non-glue dipping part of the target glue dipping hand mould 4 'when the target glue dipping hand mould reaches the lowest point of the glue dipping chain wheel 6 is always positioned above the liquid level of the liftable glue pond 2 when the target glue dipping hand mould 4' turns to rotate downwards with the fingertips. In this way, the fingertips of the hand mould are prevented from being pricked into deeper glue solution and the areas which should not be glued are glued.

Further movement is required from fig. 8 to fig. 9 and thereafter, the target impregnation die 4' continues to move toward the downstream sprocket and into the drying box for drying.

By using the production line and the method of the embodiment, the palm model 4 always faces the bottom of the liftable rubber pool 2 on one side of the palm in the rubber dipping process, so that the production requirements of semi-rubber dipped gloves are met, and the palm is dipped; according to the production requirement, the lifting height of the liquid level of the liftable glue pool 2 is controlled to carry out glue dipping on the finger part; the back of hand is not impregnated with glue. That is, the degree of impregnation on the palm side of the hand mold 4 is different from the degree of impregnation on the back side.

The gum dipping method of the semi-gum dipping glove has the advantages of the same semi-gum dipping glove production line and is not repeated.

Example two

Referring to fig. 10 and 11, in this embodiment, instead of the connecting plate 7 of the first embodiment, the connecting plate 7 of this embodiment is bent, and the position where it is connected to the hand mold bar 5 is located inward with respect to the fixed position a. Specifically, the connecting plate 7 has a fixing plate of the hand mold bar 5 and a fixing plate of the chain 3 at an angle. The fixing position A is arranged on a fixing plate of the chain 3, and the fixing plate of the chain 3 is parallel to the extending direction of the chain 3. The fixing plate of the hand mould rod 5 is bent inwards relative to the fixing plate of the chain 3, and the fixing plate of the hand mould 4 is fixed with the hand mould rod 5 through bolts. So set up, can further practice thrift the space, set up more hand mould poles 5, improve production efficiency.

In addition to the structure of the connection plates 7 of the first and second embodiments, a bent plate chain may be employed.
