Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of adhesive products, and particularly relates to an automatic pressing device on a glue brushing machine used when gluing articles. BACKGROUND

[0002] In modern product production, especially in the production of soft products such as cloth and leather, in addition to the selection of adhesive materials, the products usually need to be brushed with glue. In the brushing process, there are generally two requirements. First, the processed material must be in a relatively stable and stationary state to ensure that the processed material does not displace due to the force generated during brushing, resulting in the production of defective products. Second, the brushing must be fully covered to ensure that the processed material after brushing does not produce a bonding gap, because the bonding gap will cause the processed product to directly act on the bonding gap during use, greatly reducing the service life of the processed product.

[0003] In order to deal with the above two challenges, there are many manual operation calibration processes in the brushing process, which not only has low production efficiency and high production cost, but also has many risks to the human body. SUMMARY

[0004] The purpose of the present application is to overcome the deficiencies in the prior art and provide an automatic pressing device on a glue brushing machine.

[0005] The present application is achieved by the following technical solutions: An automatic pressing device on a glue brushing machine, comprising a workbench, further comprising a lifting unit and a rotating unit, the top of the workbench is provided with a material placing plate, the material placing plate is used for placing materials to be brushed with glue, the workbench is further provided with a first support unit, the first support unit is provided with a pressing piece above, one end of the pressing piece is connected with the support unit, and the other end can swing above the material placing plate about the connection end, the pressing piece is used for pressing, releasing and rotating to avoid the materials, the first support unit realizes the lifting function of the pressing piece through the lifting unit, the first support unit realizes the rotating function of the pressing piece through the rotating unit, the pressing piece is always located at the highest position when rotating, and when the pressing piece needs to press the materials, the pressing end of the pressing piece faces the direction of the material placing plate, and when the pressing piece needs to release the materials, the pressing end of the pressing piece faces the direction away from the material placing plate. The pressing piece can use common pressing needles and pressing tablets.

[0006] It should be noted that the working principle of the lifting unit and the rotating unit, as well as the cooperation between them, can be set by mechanical movement or controlled by electric control, such as by a motor driving a lead screw, a synchronous belt, or an air pump. These technical solutions are technical structures that can be derived by those skilled in the art without creative thinking after reading this technical solution. In addition, the first support unit here does not mean that the quantity of this technical feature is 1. If it is necessary to increase the working position of the material to be applied, the number of the first support units can be multiple, which is a simple addition of quantities.

[0007] Furthermore, the above solution includes a second support unit on the workbench, with a pressing component above the second support unit. One end of the pressing component is connected to the support unit, and the other end can swing around the connection end to the top of the feeding plate. The pressing component is used to press, release, and rotate the material to avoid it. The second support unit realizes the lifting function of the pressing component through a lifting unit and the rotation function of the pressing component through a rotating unit. The pressing component is always in the highest position when rotating. When the pressing component needs to press the material, the pressing end of the pressing component faces the feeding plate. When the pressing component needs to release the material, the pressing end of the pressing component faces a direction other than the feeding plate. The pressing component of the first support unit in the pressing state and the pressing component of the second support unit in the pressing state are not located in the same spatial position.

[0008] It should be noted that the spatial position comparison between the pressing parts of the first support unit and the second support unit in their respective pressing states refers only to the spatial position comparison when they are in their respective pressing states, and does not imply that they can be in the pressing state at the same time.

[0009] The first support unit and the second support unit cooperate in such a way that, for the same material to be coated with adhesive, the pressing parts on the first support unit and the second support unit each press once. When the pressing part of the first support unit presses the material, the pressing part of the second support unit faces outward from the material feeding plate; when the pressing part of the second support unit presses the material, the pressing part of the first support unit faces outward from the material feeding plate.

[0010] By pressing the same material separately with the pressing parts on the first support unit and the second support unit, and then applying adhesive, the adhesive application on the object to be glued can be more complete. The specific principle is that the two pressing parts alternately apply adhesive, which can solve the problem that the pressing part of a single pressing part has not been glued when pressing once. However, it should be noted that this technical solution means that during the material pressing process of the pressing parts of the first or second support unit, the movement path of the pressing parts of the other support unit will necessarily include a process in the direction away from the material feeding plate; it does not mean that during the material pressing process of the pressing parts of the first or second support unit, the pressing parts of the other support unit must be in the direction away from the material feeding plate throughout the entire process. In addition, as with the principle that the number of first support units can be multiple in the aforementioned technical solution, the number of second support units can also be multiple.

[0011] Furthermore, the above solution includes a support unit movable slot within the workbench, allowing the first support unit to move vertically up and down within this slot. The lifting unit includes a lifting slide rail located at the bottom of the workbench. This lifting slide rail is a horizontally placed track with a high surface and a low surface of varying horizontal heights. The high surface and the low surface are connected by a smooth inclined plane. The workbench can move along the trajectory of the lifting slide rail under external force, and during this movement, the lifting function of the first support unit is achieved through the horizontal difference on the lifting slide rail, thereby enabling the lifting function of the pressing component.

[0012] This technical solution can be achieved by directly abutting the bottom of the first support unit against the lifting slide rail, or by adding other components between the first support unit and the lifting slide rail. In addition, based on the principle that the number of the first support units in the aforementioned technical solution can be multiple, the number of lifting slide rails can also be multiple.

[0013] Furthermore, the above-mentioned scheme further includes a rotating unit comprising a rotating gear, a rotating rack, a rotating bracket, and a rotating slide rail. The rotating gear is arranged around and fixedly connected to the first support unit. A support unit movable slot is provided within the worktable, allowing the first support unit and the rotating gear fixedly connected to it to rotate within this slot. A rotating rack movable slot is provided laterally within the worktable, allowing the rotating rack to move laterally within this slot. The meshing surface of the rotating rack faces the rotating gear and meshes with its teeth. A protruding actuating rod is provided on the reverse side of the meshing surface of the rotating rack. The rotating slide rail is a horizontally placed track. At the bottom of the worktable, the rotary slide rail is provided with a high surface and a low surface with different horizontal heights, wherein the high surface and the low surface are transitioned by a smooth inclined surface. The worktable can move along the trajectory of the rotary slide rail under the action of external force. The worktable is also provided with a rotary support movable groove. A part of the rotary support is located in the rotary support movable groove and can move vertically up and down in the rotary support movable groove. The other part of the rotary support abuts against the rotary slide rail and drives the entire rotary support to move up and down according to the horizontal height change of the rotary slide rail. The part of the rotary support located in the rotary support movable groove is provided with an inclined rack actuation groove. The actuation rod is inserted into the rack actuation groove and drives the rotary rack to move laterally when the rotary support moves up and down.

[0014] The principle of the rotating unit is as follows: when the part of the rotating bracket that abuts against the rotating slide rail changes horizontally due to the movement of the worktable on the rotating slide rail, it will synchronously drive the part of the rotating bracket located in the rotating bracket movable slot to move vertically. Therefore, the rack actuation slot set on the rotating bracket will also move vertically at the same time. Since the rack actuation slot is set at an angle and the rotating rack movable slot is restricted, during the vertical movement of the rack actuation slot, the actuating rod located in the rack actuation slot drives the rotating rack to move laterally. When the rotating rack moves laterally, it drives the rotating gear to rotate synchronously based on the cooperation between its meshing surface and the rotating gear. The rotation of the rotating gear drives the first support unit fixedly connected to it to rotate synchronously, thereby achieving the purpose of rotating the pressing part.

[0015] Furthermore, the rotating unit includes a rotating gear, a rotating rack, a rotating bracket, and a rotating slide rail. The rotating gear is arranged around and fixedly connected to the first support unit. The worktable has a support unit movable slot, and the first support unit can move vertically up and down in the support unit movable slot. The first support unit and the rotating gear fixedly connected to the first support unit can rotate in the support unit movable slot. The lifting unit includes a lifting slide rail arranged at the bottom of the worktable. The lifting slide rail is a horizontally placed track with a high surface and a low surface with a difference in horizontal height. The high surface and the low surface are connected by a smooth inclined plane. The worktable can move along the trajectory of the lifting slide rail under the action of external force. During the movement, the lifting function of the first support unit is realized by the difference in horizontal height on the lifting slide rail, and thus the lifting function of the pressing part is realized. A rotating rack is laterally arranged in the worktable, and the rotating rack is disposed in the rotating rack and can move laterally within the rotating rack. The meshing surface of the rotating rack faces the rotating gear and meshes with the meshing teeth of the rotating gear. A protruding actuating rod is provided on the reverse side of the meshing surface of the rotating rack. The rotating slide rail is a horizontally placed track located at the bottom of the worktable. The rotating slide rail has a high surface and a low surface with different horizontal heights, wherein the high surface and the low surface are transitioned by a smooth inclined surface. The worktable can withstand external forces. The worktable is moved along the trajectory of the rotating slide rail. A rotating bracket movable slot is also provided inside the worktable. A part of the rotating bracket is located in the rotating bracket movable slot and can move vertically up and down in the rotating bracket movable slot. The other part of the rotating bracket abuts against the rotating slide rail and drives the rotating bracket to move up and down according to the horizontal height change of the rotating slide rail. An inclined rack actuation slot is provided on the part of the rotating bracket located in the rotating bracket movable slot. The actuation rod is inserted into the rack actuation slot and drives the rotating rack to move laterally when the rotating bracket moves up and down. The lifting slide rail and the rotating slide rail are parallel to each other.

[0016] Furthermore, the above solution includes a support unit movable slot within the workbench, allowing the first and second support units to move vertically up and down within this slot. The lifting unit includes a lifting slide rail located at the bottom of the workbench. This lifting slide rail is horizontally positioned and features a high surface and a low surface with a difference in horizontal height. The high and low surfaces are connected by a smooth inclined plane. The workbench can move along the trajectory of the lifting slide rail under external force, and during this movement, the horizontal difference on the lifting slide rail enables the lifting function of the first and second support units, thereby achieving the lifting function of the pressing component.

[0017] Because of the requirements for the cooperation between the first support unit and the second support unit, although the mechanisms of the two can be the same, the movement sequence of the pressing parts set on them is different. Therefore, this technical solution can be implemented either by configuring different lifting slides for the first support unit and the second support unit respectively, or by having the first support unit and the second support unit at different contact positions on the same lifting slide. These technical solutions are technical structures that can be derived by those skilled in the art without creative thinking after reading this technical solution.

[0018] Furthermore, the rotating unit includes a rotating gear, a rotating rack, a rotating bracket, and a rotating slide rail. The rotating gear is respectively arranged around the first support unit and the second support unit, and is fixedly connected to the first support unit and the second support unit respectively. A support unit movable slot is provided inside the worktable, allowing the first support unit, the second support unit, and the rotating gear respectively fixedly connected to the first support unit and the second support unit to rotate within the support unit movable slot. At least two rotating rack movable slots are arranged laterally inside the worktable. A single rotating rack is arranged within a single rotating rack movable slot and can move laterally within the rotating rack movable slot. The meshing surface of the single rotating rack faces the rotating gear and meshes only with the meshing teeth of the rotating gear of the first support unit or the second support unit. A protruding actuating rod is provided on the reverse side of the meshing surface of the rotating rack. The rotating slide rail is horizontally placed. The worktable is equipped with a rotating slide rail located at the bottom of the worktable. The rotating slide rail has a high surface and a low surface with different horizontal heights, which are smoothly transitioned by a ramp. The worktable can move along the trajectory of the rotating slide rail under the action of external force. The worktable is also equipped with a rotating bracket movable slot, the number of which corresponds to the number of rotating racks. A part of each rotating bracket is located in the rotating bracket movable slot and can move vertically up and down within the rotating bracket movable slot. The other part of the rotating bracket abuts against the rotating slide rail and drives the entire rotating bracket to move up and down according to the horizontal height change of the rotating slide rail. The part of the rotating bracket located in the rotating bracket movable slot is equipped with an inclined rack actuation slot. The actuation rod is inserted into the rack actuation slot and drives the individual rotating rack to move laterally in the individual rotating rack movable slot when the rotating bracket moves up and down.

[0019] The technical solution states that "the meshing surface of a single rotating rack faces the rotating gear and meshes only with the meshing teeth of the rotating gear of the first support unit or the second support unit." This means that a single rotating rack can mesh with a single rotating gear or with multiple rotating gears. However, when meshing with multiple rotating gears, all meshing rotating gears must originate from either the first support unit or the second support unit. That is, a single rotating rack can mesh with a plurality of rotating gears connected to a plurality of first support units or a single rotating rack can mesh with a plurality of rotating gears connected to a plurality of second support units. Conversely, the meshing rotating gears cannot include both rotating gears from the first support unit and rotating gears from the second support unit.

[0020] Furthermore, the above solution includes a rotating unit comprising a rotating gear, a rotating rack, a rotating bracket, and a rotating slide rail. The rotating gear is respectively arranged around the first support unit and the second support unit, and is fixedly connected to the first support unit and the second support unit respectively. The workbench is provided with a support unit movable slot, in which the first support unit and the second support unit can move vertically up and down. The first support unit, the second support unit, and the rotating gear respectively fixedly connected to the first support unit and the second support unit can rotate in the support unit movable slot. The lifting unit includes a lifting slide rail located at the bottom of the worktable. The lifting slide rail is a horizontally placed track with a high surface and a low surface having different horizontal heights. The high surface and the low surface are connected by a smooth inclined surface. The worktable can move along the trajectory of the lifting slide rail under the action of external force. During the movement, the lifting function of the first support unit and the second support unit is realized through the horizontal difference on the lifting slide rail, thereby realizing the lifting function of the pressing part. The worktable has at least two horizontally arranged rotating rack slots. Each rotating rack is positioned within a slot and can move laterally within it. The meshing surface of the single rotating rack faces and meshes with the teeth of the single rotating gear. A protruding actuating rod is provided on the reverse side of the meshing surface of the rotating rack. The rotating slide rail is a horizontally placed track located at the bottom of the worktable. The rotating slide rail has a high surface and a low surface with different horizontal heights, transitioned by a smooth inclined plane. The worktable can move along the trajectory of the rotating slide rail under external force. The workbench is equipped with a rotating bracket movable slot, the number of which corresponds to the number of rotating racks. A portion of each rotating bracket is located within the rotating bracket movable slot and can move vertically within it. The other portion of the rotating bracket abuts against a rotating slide rail and moves the entire rotating bracket up and down according to the horizontal height of the slide rail. The portion of the rotating bracket located within the rotating bracket movable slot is provided with an oblique rack actuation slot. The actuation rod is inserted into the rack actuation slot and, when the rotating bracket moves up and down, drives the individual rotating rack to move laterally within the individual rotating rack movable slot. The lifting slide rail and the rotating slide rail are parallel to each other.

[0021] It should be noted that those skilled in the art can conclude without creative thinking after reading this technical solution that if a plurality of lifting slide rails or a plurality of rotating slide rails appear in a specific embodiment, they are all parallel.

[0022] Furthermore, the above-mentioned solution further includes a lifting bracket assembly, which includes a first lifting bracket and a lifting limit device. The first lifting bracket is connected to the bottom of the first support unit. The first lifting bracket is also provided with a slider, which abuts against the lifting slide rail. The lifting limit device is provided between the first lifting bracket and the worktable and is used to limit the movement direction of the first lifting bracket to ensure that the entire lifting bracket moves with the change of the horizontal position of the slider. The lifting limit device consists of a lifting limit protrusion provided on the worktable and a lifting limit groove provided on the first lifting bracket. The lifting limit protrusion and the lifting limit groove are positioned correspondingly. A slider is provided at the bottom of the rotating bracket, and the slider abuts against the rotating slide rail. Those skilled in the art can conclude without creative thinking after reading this technical solution that when the slider on the rotating bracket is near or located on the inclined surface of the rotating slide rail, the slider on the lifting bracket is always located on the high surface of the lifting slide rail, so that the pressing part is always in the highest position when rotating. When the pressing part needs to press the material, the pressing end of the pressing part faces the direction of the discharging plate, and when the pressing part needs to release the material, the pressing end of the pressing part faces the direction other than the discharging plate.

[0023] The first lifting bracket is applicable to multiple first support units generated due to the need for multiple working positions. Under the premise of only being equipped with one lifting slide rail, the first lifting bracket can be connected to the bottom of multiple first support units at multiple ends to achieve synchronous lifting of multiple ends of a single rail. However, this explanation does not constitute a technical limitation on this technical feature, that is, a single first support unit can still adopt the first lifting bracket grafting structure.

[0024] It should be noted that although the lifting limit device described in this technical solution uses a limiting protrusion set on the worktable and a lifting limit groove set on the first lifting bracket, exchanging the positions of these two technical features can still produce the exact same technical effect. This is a technical structure that can be derived by those skilled in the art without creative thinking after reading this technical solution. In addition, the "slider" mentioned here includes not only components with sliding or rolling effects connected to the outside of the lifting bracket, but also integrated parts with sliding or rolling effects extending from the lifting bracket body.

[0025] The lifting unit further includes a lifting bracket assembly, which includes a first lifting bracket, a second lifting bracket, and a lifting limit device. The first lifting bracket is connected to the bottom of the first support unit and is equipped with a slider that abuts against a lifting slide rail. The second lifting bracket is connected to the bottom of the second support unit and is also equipped with a slider that abuts against a lifting slide rail. Lifting limit devices are provided between the first lifting bracket and the worktable, and between the second lifting bracket and the worktable, to limit the movement direction of the first and second lifting brackets to ensure that the first and second lifting brackets as a whole move with the change of the horizontal position of the slider. The lifting limit device consists of a lifting limit protrusion on the worktable and a lifting limit groove on the first or second lifting bracket. The lifting limit protrusion and the lifting limit groove are positioned correspondingly, and the movement connection between the first and second lifting brackets is independent of each other.

[0026] This invention achieves a high degree of automation in the adhesive application process of materials such as leather and fabric in industrial production by setting different motion logics for pressing components. It not only effectively solves the problem of excessive manual labor in related workflows in the industry, but also solves the problem of the integrity of adhesive application on the processed products, effectively reducing production costs and improving production efficiency and product qualification rate.

[0028] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.

[0029] It should be noted that in the description of this embodiment, the terms "front", "rear", "up", "down", "left", "right", "front", "rear", "middle", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.

[0030] like Figure 1 As shown, an automatic pressing device on a glue application machine includes a worktable 1. The worktable is divided into a front cover plate 11, a base 12, and a rear cover plate 13 from front to back. A double-station material feeding plate 6 is fixedly connected to the top of the worktable 1. Two "b"-shaped pressure pins 14 are provided on the left and right sides of the top of the worktable 1. One end of the pressure pin 14 is connected to the top of the worktable 1, and the other end of the pressure pin 14 can swing around the connecting end. A slide rail assembly 2 is provided at the bottom of the worktable 1.

[0031] like Figure 2As shown, a first lifting bracket 31 and a second lifting bracket 32 ​​are provided above the slide rail assembly 2. The first lifting bracket 31 is connected to the bottom of the two first support columns 15 on both sides of the slide rail assembly 2, and the second lifting bracket 32 ​​is connected to the bottom of the two second support columns 16 on both sides of the slide rail assembly 2. A lifting limit groove 33 is provided on the first lifting bracket 31 and the second lifting bracket 32 ​​near the front cover plate 11. A lifting limit protrusion 34 is provided on the front cover plate 11 at the position corresponding to the lifting limit groove 33. A semi-circular protruding slider 5 is provided at the bottom position between the first lifting bracket 31 and the second lifting bracket 32 ​​near the slide rail assembly 2.

[0032] like Figure 3 As shown, the slide rail group 2 includes a lifting slide rail 21 and a rotating slide rail 22. The leftmost and rightmost tracks are rotating slide rails 22, and the two middle tracks are lifting slide rails 21. The two rightmost tracks in the track group are first support columns 16 providing lifting and rotating functions, and the two leftmost tracks are second support columns 17 providing lifting and rotating functions. Both the lifting slide rail 21 and the rotating slide rail 22 have a high surface 23 and a low surface 24 with different horizontal heights. The high surface 23 and the low surface 24 are connected by a smooth inclined surface 25. In this embodiment, the part of the rotating slide rail 22 that is parallel to the lifting slide rail 21 and has no track is the low surface 24 part of the rotating slide rail 22.

[0033] like Figures 4 to 6 As shown, the workbench 1 is also equipped with two first support columns 15 and two second support columns 16. A "b"-shaped pressure pin 14 is fixedly connected to the top of the first support column 15 and the second support column 16. The bottom of the first support column 15 is connected to the first lifting bracket 31, and the bottom of the second support column 16 is connected to the second lifting bracket 32. A rotating gear 41 is provided at the upper middle position of the two first support columns 15 connected to the first lifting bracket 31. A rotating gear 41 is provided at the lower middle position of the two second support columns 16 connected to the second lifting bracket 32. The two first support columns 15 and the two second support columns 16 are all set in four support column movable slots 17 between the base 12 and the front cover plate 11. These four support column movable slots 17 are formed by the front cover plate 11 and the base 12 and can accommodate the first support column 15, the second support column 16 and the rotating gear 41 fixedly connected to them to perform lifting and rotating actions in their respective support column movable slots 17.

[0034] like Figures 7 to 10As shown, two rotating rack movable slots 18 and two rotating support movable slots 19 are arranged between the base 12 and the rear cover plate 13. The rotating rack movable slots 18 are arranged laterally in parallel with each other on the side of the base 12 facing the rear cover plate 13. Each of the two rotating rack movable slots 18 is provided with a rotating rack 42. Both rotating racks 42 can move laterally in their respective rotating rack movable slots 18. The meshing surface of the upper rotating rack 42 meshes with the rotating gears 41 on the two first support columns 15, and the meshing surface of the lower rotating rack 42 meshes with the rotating gears 41 on the two second support columns 15. The rotating gears 41 on the column 16 mesh with each other, and the rotating rack 42 is provided with a protruding columnar actuating rod 421 facing the rear cover plate 13; the rotating bracket movable slots 19 are arranged vertically in parallel to each other in the rear cover plate 13 facing the base 12, and each of the two rotating bracket movable slots 19 is provided with a rotating bracket 43. The bottom of the rotating bracket 43 is provided with a semi-circular protruding slider 5, which abuts against the rotating slide rail 22. The upper half of the rotating bracket 43 is provided with an inclined rack actuating slot 431, and the actuating rod 421 is sleeved in the inclined rack actuating slot 431.

[0035] In this embodiment, when the rotating bracket 43, which is indirectly connected to the second support column 16, is at the high position 23, the swing end of the pressure needle 14 connected to the top of the second support column 16 is at the furthest point from the feeding plate 6. When the rotating bracket 43, which is dynamically connected to the second support column 16, is at the low position 24, the swing end of the pressure needle 14 connected to the top of the second support column 16 is directly above the feeding plate 6. When the rotating bracket 22, which is dynamically connected to the first support column 15, is at the high position, the swing end of the pressure needle 14 connected to the top of the first support column 15 is directly above the feeding plate 6. When the rotating bracket 22, which is dynamically connected to the first support column 15, is at the low position 24, the swing end of the pressure needle 14 connected to the top of the first support column 15 is at the furthest point from the feeding plate 6.

[0036] In this embodiment, the two materials on the feeding plate 6 are first placed below the swing ends of the pressure needles 14 on the tops of the two first support columns 15. After starting the worktable 1, the worktable 1 moves from back to front along the slide rail assembly 2 under the action of external force. At this time, it can be seen from the track distribution that the lifting slide rails 21 are all located at the low plane and the rotating slide rails 22 are all located at the high plane. Therefore, the swing ends of the pressure needles 14 connected to the tops of the two first support columns 15 are located directly above the feeding plate 6 and the pressure needles 14 are at their lowest position. That is, the pressure needles 14 connected to the tops of the two first support columns 15 are in the material pressing state, while the swing ends of the pressure needles 14 connected to the tops of the two second support columns 16 are located away from the feeding plate. At the furthest point of position 6, where the pressure pins 14 connected to the tops of the two second support columns 16 are in a state of releasing material, the compressed material can be coated with adhesive for the first time. After the adhesive coating is completed, as the worktable 1 continues to move from back to front, the slider 5 on the left side of the slide rail group 2 will undergo its first change. Because the worktable 1 also has its own thickness, the slider 5 located above the middle left track will actually change first. When the slider 5 moves from the low surface 24 to the high surface 23, it will drive the second lifting bracket 32 ​​connected to it to rise synchronously, and then drive the second support column 16 connected to the second lifting bracket 32 ​​to rise synchronously until the second support column 16... When the pressure needle 14 connected at the top reaches its highest position, the slider 5 above the leftmost track of the slide rail assembly 2 gradually approaches the inclined plane 25 and prepares to move from the high plane 23 to the low plane 24. As the slider 5 above the leftmost track of the slide rail assembly 2 slides down from the high plane 23 to the low plane 24, the middle left track of the slide rail assembly 2 turns from the high plane 23 to the low plane 24 again, so that the swing end of the pressure needle 14 on the second support column 16 is directly above the feeding plate 6 and the pressure needle 14 is at its lowest position, that is, the pressure needle 14 on the second support column 16 is in the material pressing state. Then, as the worktable 1 continues to move from back to front, the slider 5 on the middle right track of the slide rail assembly 2 moves from the low plane 24 to the material pressing state. The high position 23 drives the first lifting bracket 31 connected to it to rise synchronously. The first lifting bracket 31 rises synchronously, driving the first support column 15 connected to it to rise synchronously. When the pressure needle 14 connected to the top of the first support column 15 reaches the highest position, the slider 5 above the rightmost rail of the slide rail group 2 gradually approaches the inclined plane 25 and prepares to move from the high position 23 to the low position 24. As the slider 5 above the rightmost rail of the slide rail group 2 slides from the high position 23 to the low position 24, the swing end of the pressure needle 14 connected to the top of the first support column 15 is at the farthest point from the discharge plate 6. The material on the discharge plate 6 can be coated with glue for the second time. The material on the discharge plate 6 is then coated with glue.
