Description

Technical Field

[0001] This utility model relates to a glue coating machine, belonging to the field of glue coating technology for sheet materials. Background Technology

[0002] With increasing emphasis on environmental protection, energy conservation, and sustainable development, the advantages of timber-framed buildings as a green, environmentally friendly, and energy-efficient building form are self-evident. Wood is a poor conductor of heat, possessing excellent thermal insulation properties, which effectively regulates the indoor temperature of wooden houses. This allows timber-framed buildings to remain warm in winter and cool in summer, reducing the need for heating and air conditioning, thus saving energy and reducing energy consumption.

[0003] The wall panels, floor slabs, and other components required for wooden structure buildings can be prefabricated in a modular manner in the factory and then transported to the site for assembly. This not only makes the assembly process convenient and quick with a short construction period, but also eliminates construction waste during on-site assembly, resulting in high construction efficiency and low labor costs.

[0004] Because the wall panels and floor slabs in wooden structures involve large dimensions, generally exceeding 6 meters in length and width, obtaining them directly from logs is difficult. Therefore, a common method is to rotary cut logs into wood chips or sawn into wood blocks and then splice them into layers. Adjacent layers are glued together, and the gluing process is tailored to the required thickness of the wood panels for the wooden structure. The gluing process involves laying one layer of panel, applying glue, then laying another layer, applying glue again, and so on, until the required thickness is achieved. Therefore, a glue-applying machine with a simple structure, high glue-applying efficiency, and the ability to automate the glue-applying process for the panels is needed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a glue coating machine.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A glue-applying machine includes a frame and a glue-applying device arranged on the frame. The glue-applying device includes a glue-applying beam and a glue-applying mechanism arranged on the glue-applying beam. The frame is provided with a board support mechanism for carrying the board. The glue-applying beam spans across the frame and moves along the length of the frame under the action of the glue-applying traveling mechanism to apply glue to the surface of the board.

[0007] The glue-spraying mechanism includes a glue-spraying lifting frame and multiple glue-spraying components installed on the glue-spraying lifting frame. The glue-spraying lifting frame is connected to the glue-spraying beam frame through the glue-spraying lifting mechanism. The glue-spraying components can move up and down under the action of the glue-spraying lifting mechanism.

[0008] The beneficial effects of this utility model are as follows: The sheet material is placed on the sheet material support mechanism. Under the action of the glue-spraying walking mechanism, the glue-spraying beam carrying the glue-spraying components can move on the frame. The glue-spraying components move longitudinally to perform glue-spraying operations on the sheet material. Multiple glue-spraying components can be rationally arranged according to the transverse length of the sheet material. For example, the transverse arrangement of multiple glue-spraying components can match the transverse length of the sheet material. The glue-spraying components can complete the glue-spraying operation on the sheet material surface in one longitudinal movement or one back-and-forth longitudinal movement. The glue-spraying components are not only able to move longitudinally, but their height is also adjustable. The height of the glue-spraying components can be adjusted through the glue-spraying lifting mechanism, allowing the glue-spraying components to maintain a suitable glue-spraying height for sheets of different heights. This utility model has a simple structure, is easy to operate, has high glue-spraying efficiency, and can realize automated glue-spraying operations for sheet materials.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the glue-spraying mechanism also includes a glue-spraying mounting frame and a glue-spraying path adjustment mechanism. Multiple glue-spraying components are mounted on the glue-spraying mounting frame, which is hinged to the glue-spraying lifting frame. The glue-spraying mounting frame can swing left and right under the action of the glue-spraying path adjustment mechanism.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, due to the influence of components such as the housing of the glue-applying assembly, there will be a certain gap between adjacent glue-applying heads. For example, the gap between the glue-applying lines formed by the longitudinal movement of the glue-applying assembly is about 20mm. Even if the glue-applying assembly applies glue again on its return, because the return glue-applying position coincides with the first glue-applying position, there will still be areas between adjacent glue-applying lines that cannot be glued. This will result in poor glue-applying quality in that part of the board after gluing. Furthermore, the board after gluing still needs to be cut. For example, if the cutting is done to form a window installation position, and the cutting position happens to be in an un-glued area between adjacent glue-applying lines, the quality of the board at that point will be poor, affecting the quality and appearance of the wooden structure building. To ensure the glue-applying quality of the board, the glue-applying path of the glue-applying assembly is designed to be adjustable. The glue-spraying assembly is mounted on the glue-spraying mounting frame. Under the action of the glue-spraying path adjustment mechanism, the mounting frame can move relative to the glue-spraying lifting frame. For example, when the glue-spraying assembly returns longitudinally, the position of the mounting frame can be adjusted through the glue-spraying path adjustment mechanism so that the returned glue-spraying position is offset from the previous glue-spraying position and no longer coincides. It can be adjusted to be between the previously adjacent glue-spraying lines. Thus, if there was originally a 20mm gap, it will be adjusted to 10mm. After passing through the press, the glue can fully bond the adjacent layers. Of course, the glue-spraying path adjustment can not only form a straight glue-spraying path, but also a wavy glue-spraying path. Through the design of the glue-spraying path adjustment mechanism, the glue-spraying path of the glue-spraying machine is adjustable, allowing the selection of a suitable adjustment path according to the needs of the board material, in order to obtain better board bonding quality.

[0012] Furthermore, the adhesive application path adjustment mechanism includes an adjustment drive cylinder, the cylinder body of which is mounted on the adhesive application lifting frame, and the piston rod of which can drive the adhesive application mounting frame to swing left and right.

[0013] Alternatively, the adhesive application path adjustment mechanism includes an eccentric bearing and an adjustment motor for driving the eccentric bearing to rotate. The adjustment motor is mounted on the adhesive application lifting frame, and the outer ring of the eccentric bearing drives the adhesive application mounting frame to swing left and right through a connecting rod.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the glue application path adjustment mechanism can adopt an adjustment drive cylinder, and the left and right positions of the glue application mounting frame can be adjusted directly by adjusting the extension and retraction of the piston rod of the drive cylinder, thereby adjusting the glue application path of the glue application assembly; of course, the glue application mounting frame can also be driven by adjusting the cooperation of the motor and the eccentric bearing.

[0015] Furthermore, the adjusting motor is connected to the eccentric bearing via an adjusting transmission mechanism;

[0016] The adjusting transmission mechanism includes a bushing, a transmission shaft fitted inside the bushing, a first transmission wheel, a second transmission wheel, and a transmission belt wrapped around the first and second transmission wheels. The bushing is mounted on the glue-applying lifting frame, the first transmission wheel is mounted on the output shaft of the adjusting motor, the second transmission wheel is mounted on one end of the transmission shaft, and the other end of the transmission shaft is connected to the eccentric bearing.

[0017] The beneficial effect of adopting the above-mentioned further solution is that an adjustment transmission mechanism can also be set between the adjustment motor and the eccentric bearing, and the power of the adjustment motor can be transmitted to the eccentric bearing through the adjustment transmission mechanism.

[0018] Furthermore, at least two connecting mechanisms are provided between the glue-applying lifting frame and the glue-applying mounting frame. The connecting mechanism includes a first hinge seat disposed on the glue-applying lifting frame, a second hinge seat disposed on the glue-applying mounting frame, and a connecting block connecting the first hinge seat and the second hinge seat. One end of the connecting block is connected to the first hinge seat through a first hinge shaft, and the other end is connected to the second hinge seat through a second hinge shaft. The free end of the piston rod or connecting rod of the adjusting drive cylinder is hinged to the second hinge shaft.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the connecting mechanism realizes the hinge between the glue-spraying mounting frame and the glue-spraying lifting frame, so that the glue-spraying mounting frame can swing relative to the glue-spraying lifting frame. In this way, the glue-spraying mounting frame can be driven by adjusting the drive cylinder or adjusting the motor.

[0020] Furthermore, it also includes a stop-glue protection tank, which is provided with an isolation solution for the glue-spraying assembly to be immersed in when glue spraying stops.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the adhesive remains in a flowing state during the glue application process and will not solidify. However, after the glue application of one layer of boards is completed, it is necessary to wait for the boards to be loaded or unloaded after glue application. During this period, the glue application component will stop applying glue, and there will be a situation where the adhesive at the glue outlet of the glue application component solidifies. To address this, a glue stop protection tank is designed. The glue stop protection tank contains an isolation solution. When the glue application component stops applying glue, its glue outlet can be placed in the isolation solution in the glue stop protection tank. Because the glue outlet is in the isolation solution in the glue stop protection tank, the adhesive will not solidify when glue application stops, thus making full preparations for the glue application after the next layer of boards is laid.

[0022] Furthermore, it also includes a shelf loading mechanism, which includes a loading frame and a loading trolley that travels laterally on the loading frame. One side of the frame is provided with a horizontally textured board material position, and the other side is provided with a vertically textured board material position. The loading frame spans the horizontally textured board material position and the vertically textured board material position. The loading trolley includes a frame and a loading lifting frame mounted on the frame. The loading lifting frame is provided with multiple vacuum suction cups for adsorbing horizontally textured boards and vertically textured boards. Under the action of the moving drive mechanism, the frame can move the boards on the vertically textured board position and the horizontally textured board position to the board support mechanism. The loading lifting frame is mounted on the frame through the loading lifting mechanism.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the feeding of the board can be automated by the layer feeding mechanism. In order to ensure the quality of the board after gluing, layers with different textures can be used. A vacuum suction cup adsorbs a layer of horizontally textured board and feeds it onto the board support mechanism, and then glue is applied by the glue application component. After that, the vacuum suction cup adsorbs a layer of vertically textured board and feeds it onto the horizontally textured board for glue application, and so on, until the board of the required thickness is obtained. The automated board feeding combined with the automated glue application further improves the glue application efficiency of the board.

[0024] Furthermore, the bottom of the loading lifting frame is provided with multiple inclined suction cup mounting plates, and the vacuum suction cup is mounted on the suction cup mounting plate.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the vacuum suction cup can not only adsorb horizontally textured boards, but also vertically textured boards. In order to adsorb horizontally textured boards and vertically textured boards more stably, the vacuum suction cup is arranged on the suction cup mounting plate with an inclined setting. In this way, the vacuum suction cup can fully contact the board, improve the adsorption effect, and also work together with the lateral movement of the board to improve the board feeding efficiency.

[0026] Furthermore, the adhesive coating traveling mechanism includes a gear, a rack meshing with the gear, and a traveling motor for driving the gear to rotate. The traveling motor is mounted on the adhesive coating beam, the gear is mounted on the output shaft of the traveling motor, and the rack is mounted on the frame.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the walking motor drives the gear to rotate, the rack is fixed on the side of the frame, the gear meshes with the rack and the rotation of the gear realizes the movement of the glue-coating beam on the frame, thereby realizing the longitudinal movement of the glue-coating assembly.

[0028] Furthermore, the adhesive application lifting mechanism includes a sleeve, a lifting screw rotatably disposed within the sleeve, and a screw sleeve threadedly connected to the lifting screw. The lifting screw is rotatable under the action of a power mechanism. The lifting screw is rotatably disposed on the adhesive application beam frame. The screw sleeve is connected to the adhesive application lifting frame, and the sleeve is disposed on the adhesive application beam frame.

[0029] The beneficial effect of adopting the above-mentioned further solution is that when the power mechanism is activated, the lifting screw rotates, the screw sleeve can move along the axial direction of the lifting screw, and the glue-spraying lifting frame connected to the screw sleeve can move up and down, thereby realizing the adjustment of the height of the glue-spraying assembly.

[0030] Furthermore, the plate support mechanism includes a support conveyor belt and a conveyor motor for driving the support conveyor belt. The support conveyor belt is wrapped around a drive wheel and a driven wheel. The output shaft of the conveyor motor is connected to the drive wheel, or the conveyor motor is connected to the drive wheel through a conveyor transmission mechanism.

[0031] The beneficial effect of adopting the above-mentioned further solution is that the board is supported by the board support mechanism during the glue application process, and after the glue application is completed, it can also be transported out by the board support mechanism; after the board is glued, the conveyor motor is activated, the drive wheel rotates, and the support conveyor belt can carry the glued board out, and the board can be moved to the next board processing step.

[0046] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0047] Example 1, as Figures 1-7 As shown, a glue-applying machine includes a frame 1 and a glue-applying device mounted on the frame 1. The glue-applying device includes a glue-applying beam 2 and a glue-applying mechanism mounted on the glue-applying beam 2. The frame 1 is provided with a board support mechanism for supporting the board. The glue-applying beam 2 spans across the frame 1 and moves along the length of the frame 1 under the action of the glue-applying traveling mechanism to apply glue to the surface of the board.

[0048] The glue-applying mechanism includes a glue-applying lifting frame 3 and multiple glue-applying components 5 disposed on the glue-applying lifting frame 3. The glue-applying lifting frame 3 is connected to the glue-applying beam frame 2 through the glue-applying lifting mechanism. The glue-applying components 5 can move up and down under the action of the glue-applying lifting mechanism.

[0049] The glue-applying mechanism also includes a glue-applying mounting frame 4 and a glue-applying path adjustment mechanism. Multiple glue-applying components 5 are mounted on the glue-applying mounting frame 4, which is hinged to the glue-applying lifting frame 3. The glue-applying mounting frame 4 can swing left and right under the action of the glue-applying path adjustment mechanism. Due to the influence of components such as the housing of the glue-applying components 5, there will be a certain gap between adjacent glue-applying heads. For example, the gap between the glue-applying lines formed by the longitudinal movement of the glue-applying components 5 is approximately 20mm. Even if the glue-applying components 5 apply glue again upon returning, because the return glue-applying position coincides with the first glue-applying position, there will still be areas between adjacent glue-applying lines that cannot be glued. This will result in poor glue-applying quality in that part of the board after gluing. Furthermore, the board after gluing needs to be cut subsequently, such as to form window installation positions. If the cutting position happens to be an un-glued area between adjacent glue-applying lines, the quality of the board at that point will be poor, affecting the quality and appearance of the wooden structure building. To ensure the glue-applying quality of the board, the glue-applying path of the glue-applying components 5 is designed to be adjustable. The glue-spraying assembly 5 is installed on the glue-spraying mounting frame 4. Under the action of the glue-spraying path adjustment mechanism, the glue-spraying mounting frame 4 can swing relative to the glue-spraying lifting frame 3. When the glue-spraying assembly 5 returns longitudinally, the position of the glue-spraying mounting frame 4 can be adjusted by the glue-spraying path adjustment mechanism so that the returned glue-spraying position is staggered from the previous glue-spraying position and no longer coincides. It can be adjusted to be between the previous adjacent glue-spraying lines. In this way, if there was originally a 20mm gap, it will be adjusted to 10mm. After passing through the press, the glue can fully bond the adjacent boards. Of course, the glue-spraying path adjustment can not only form a straight glue-spraying path, but also swing to form a wavy glue-spraying path. Through the design of the glue-spraying path adjustment mechanism, the glue-spraying path of the glue-spraying machine is adjustable, and a suitable adjustment path can be selected according to the needs of the board to obtain better board bonding quality.

[0050] The adhesive path adjustment mechanism includes an adjustment drive cylinder 6. The cylinder body of the adjustment drive cylinder 6 is mounted on the adhesive lifting frame 3 via a cylinder body seat. The piston rod of the adjustment drive cylinder 6 can drive the adhesive mounting frame 4 to swing left and right. The adhesive path adjustment mechanism can use an adjustment drive cylinder, and the left and right positions of the adhesive mounting frame 4 can be adjusted directly by adjusting the extension and retraction of the piston rod of the adjustment drive cylinder 6, thereby adjusting the adhesive path of the adhesive assembly 5.

[0051] At least two connecting mechanisms are provided between the glue-applying lifting frame 3 and the glue-applying mounting frame 4. Each connecting mechanism includes a first hinge seat 14 mounted on the glue-applying lifting frame 3, a second hinge seat 15 mounted on the glue-applying mounting frame 4, and a connecting block 16 connecting the first hinge seat 14 and the second hinge seat 15. One end of the connecting block 16 is connected to the first hinge seat 14 via a first hinge shaft, and the other end is connected to the second hinge seat 15 via a second hinge shaft. The piston rod of the adjusting drive cylinder is hinged to the second hinge shaft. These connecting mechanisms enable the glue-applying mounting frame 4 and the glue-applying lifting frame 3 to hinge, allowing the glue-applying mounting frame 4 to swing relative to the glue-applying lifting frame 3. This swinging drive of the glue-applying mounting frame 4 can then be achieved by adjusting the drive cylinder.

[0052] It also includes a stop-glue protection tank 17, which contains an isolation solution for the glue-spraying assembly 5 to be immersed in when glue spraying stops. During the glue spraying process, the glue is in a flowing state and will not solidify. However, after one layer of boards is sprayed, it is necessary to wait for the boards to be loaded or unloaded. During this period, the glue spraying assembly 5 will stop spraying, and the glue at the glue outlet of the glue spraying assembly 5 may solidify. For this reason, the stop-glue protection tank 17 is designed. The stop-glue protection tank 17 contains an isolation solution. When the glue spraying assembly 5 stops spraying, its glue outlet can be placed in the isolation solution in the stop-glue protection tank 17. When glue spraying stops, the glue will not solidify because the glue outlet is in the isolation solution in the stop-glue protection tank 17, thus making full preparation for the glue spraying after the next layer of boards is laid.

[0053] The isolation solution can be an organic solvent. When the adhesive application assembly's nozzle stops applying adhesive, it can be immersed in the isolation solution to prevent the adhesive from curing upon contact with air. For example, the organic solvent can be methyl acetate or other solvents that can dilute the adhesive.

[0054] The adhesive coating traveling mechanism includes a gear, a rack 18 meshing with the gear, and a traveling motor for driving the gear to rotate. The traveling motor is mounted on the adhesive coating beam 2, the gear is mounted on the output shaft of the traveling motor, and the rack 18 is mounted on the frame 1. The traveling motor drives the gear to rotate, and the rack 18 is fixed to the side of the frame 1. The gear meshes with the rack 18, and as the gear rotates, the adhesive coating beam 2 moves on the frame 1, thereby realizing the longitudinal movement of the adhesive coating assembly 5.

[0055] The adhesive application lifting mechanism includes a sleeve 21, a lifting screw 19 rotatably disposed within the sleeve 21, and a screw sleeve 20 threadedly connected to the lifting screw 19. The lifting screw 19 can rotate under the action of a power mechanism. The lifting screw 19 is rotatably mounted on the adhesive application beam 2. The output end of the power mechanism is connected to the lifting screw 19. The screw sleeve 20 is connected to the adhesive application lifting frame 3. The sleeve 21 is mounted on the adhesive application beam 2. When the power mechanism is activated, the lifting screw 19 rotates, and the screw sleeve 20 moves along the axial direction of the lifting screw 19. The adhesive application lifting frame 3 connected to the screw sleeve 20 can move up and down, thereby adjusting the height of the adhesive application assembly 5.

[0056] The adhesive application lifting mechanism is provided in two sets. The power mechanism includes a lifting motor 22, a lifting shaft 23, a lifting main bevel gear, and a lifting driven bevel gear meshing with the lifting main bevel gear. The lifting shaft 23 is rotatably mounted on the adhesive application beam 2 and is connected to the output end of the lifting motor 22. There are two lifting main bevel gears, which are respectively located at both ends of the lifting shaft 23. The lifting driven bevel gear is mounted on the lifting lead screw 19. The synchronous lifting drive of the two sets of adhesive application lifting mechanisms can be achieved by a single lifting motor 22.

[0057] The sheet material support mechanism includes a support conveyor belt 24 and a conveyor motor for driving the support conveyor belt 24. The support conveyor belt 24 is wrapped around a drive wheel and a driven wheel. The output shaft of the conveyor motor is connected to the drive wheel, or the conveyor motor is connected to the drive wheel through a conveyor transmission mechanism. The sheet material is supported by the sheet material support mechanism during the glue application process. After glue application, the sheet material can be conveyed out by the sheet material support mechanism. After glue application, the conveyor motor actuates, the drive wheel rotates, and the support conveyor belt 24 carries the glued sheet material out, allowing the sheet material to be moved to the next sheet material processing step.

[0058] The conveying transmission mechanism includes a first sprocket, a second sprocket, and a transmission chain surrounding the first sprocket and the second sprocket. The first sprocket is connected to the output shaft of the conveying motor, and the second sprocket is mounted on the axle of the drive wheel.

[0059] The frame 1 is provided with a slide rail 25 for moving the adhesive-coated beam 2, and the adhesive-coated beam 2 is provided with rollers 26 that travel on the slide rail 25. This reduces the friction of the adhesive-coated beam 2 as it travels on the frame 1.

[0060] The adhesive application assembly 5 includes an adhesive application valve body, a valve stem 503 mounted on the valve body, an elastic sealing plate 504 mounted inside the valve body, and an adhesive application drive cylinder 506 for driving the valve stem 503 axially. The adhesive application valve body is mounted on the adhesive application mounting bracket 4. The valve body has at least one valve chamber, and each valve chamber contains one valve stem 503. The inner edge of the elastic sealing plate 504 is sealed to the valve stem 503, and the outer edge of the elastic sealing plate 504 is sealed to the valve body. The adhesive application valve body has corresponding adhesive inlet holes 505 communicating with each valve chamber. The adhesive inlet holes 505 are connected to an adhesive source via an adhesive supply pipe. Adhesive can enter the adhesive chamber through the adhesive supply pipe and the adhesive inlet holes 505. The elastic deformation of the elastic sealing plate can meet the requirements of axial movement of the valve stem 503. The elastic sealing sheet 504 has a good sealing effect. When the valve stem 503 moves axially, the elastic sealing sheet 504 can always maintain a sealed connection. The glue in the glue application assembly 5 will not be carried out by the valve stem 503 and will always remain in the glue cavity. Air will also enter the glue cavity through the space between the elastic sealing sheet 504 and the valve stem 503, affecting the flow of glue in the glue gun and preventing the glue from contacting the air and curing.

[0061] The adhesive-coated valve body includes an upper valve body 502 and a lower valve body 501, with the elastic sealing sheet 504 disposed between the upper valve body 502 and the lower valve body 501. The valve body adopts a two-part structure, which facilitates the sealing installation between the elastic sealing sheet 504 and the valve body.

[0062] The elastic sealing sheet 504 is connected to the valve stem 503 via an upper fixing ring 507 and a lower fixing ring 508. The elastic sealing sheet 504 is fitted onto the valve stem 503, and the upper and lower fixing rings 508 are fitted onto the valve stem 503 and act on the top and bottom of the elastic sealing sheet 504 respectively to achieve a sealing connection between the elastic sealing sheet 504 and the valve stem 503.

[0063] The outer edge of the elastic sealing sheet 504 has an outer ring protrusion that seals with the adhesive-coated valve body. The inner edge of the elastic sealing sheet 504 has an inner ring protrusion that seals with the valve stem 503. The valve body has a corresponding groove for accommodating the outer ring protrusion, and the upper and lower fixing rings 508, after mating, have a groove for accommodating the inner ring protrusion. The protrusions further enhance the sealing connection between the elastic sealing sheet 504 and the valve body or valve stem 503, preventing the elastic sealing sheet 504 from detaching from the valve body or valve stem 503 when the valve stem 503 moves axially.

[0064] When there are multiple valve stems 503, the piston rod of the glue-spraying drive cylinder 506 is connected to the valve stems 503 through a connector 509. If the glue-spraying valve body has three valve chambers, each valve chamber contains a valve stem 503 and an elastic sealing sheet 504, it can realize the axial movement control of multiple valve stems 503 of a glue-spraying assembly 5, thereby achieving the purpose of glue spraying and stopping.

[0065] Example 2, as Figure 8 and Figure 9 As shown, it also includes a shelf loading mechanism, which includes a loading rack 27 and a loading trolley that travels laterally on the loading rack 27. One side of the frame 1 is provided with a horizontally textured plate material position 28 and the other side is provided with a vertically textured plate material position 29. The loading rack 27 spans the horizontally textured plate material position 28 and the vertically textured plate material position 29. The loading trolley includes a frame and a loading lifting frame 30 set on the frame. The loading lifting frame 30 is provided with multiple vacuum suction cups for adsorbing horizontally textured plates and vertically textured plates. Under the action of the moving drive mechanism, the frame can move the plates on the vertically textured plate position and the horizontally textured plate position to the plate support mechanism. The loading lifting frame 30 is set on the frame through the loading lifting mechanism. The feeding of the sheet material can be automated through a layer feeding mechanism. To ensure the quality of the sheet material after gluing, layers with different textures can be used. A vacuum suction cup picks up a layer of horizontally textured sheet material and feeds it onto the sheet material support mechanism, then applies glue through the glue application component 5. Next, the vacuum suction cup picks up a layer of vertically textured sheet material and feeds it onto the horizontally textured sheet for glue application, and so on, until the desired sheet thickness is obtained. Automated sheet material feeding combined with automated glue application further improves the glue application efficiency. The feeding lifting mechanism includes at least one lifting hydraulic cylinder. The piston rod of the lifting hydraulic cylinder is connected to the feeding lifting frame 30.

[0066] The bottom of the loading lifting frame 30 is provided with multiple inclined suction cup mounting plates 31, and the vacuum suction cups are mounted on the suction cup mounting plates 31. The vacuum suction cups need to adsorb not only horizontally ribbed materials but also vertically ribbed materials. In order to adsorb horizontally ribbed and vertically ribbed materials more stably, the vacuum suction cups are arranged on the inclined suction cup mounting plates 31. In this way, the vacuum suction cups can fully contact the materials, improve the adsorption effect, and also work together with the lateral movement of the materials to improve the loading efficiency of the materials.

[0067] Example 3, as Figures 10-13As shown, the adhesive application path adjustment mechanism includes an eccentric bearing 8 and an adjusting motor 7 for driving the eccentric bearing 8 to rotate. The adjusting motor 7 is mounted on the adhesive application lifting frame 3. The outer ring of the eccentric bearing 8 drives the adhesive application mounting frame 4 to swing left and right via a connecting rod. The output shaft of the driving motor is connected to the eccentric bearing shaft of the eccentric bearing 8 to drive the eccentric bearing to rotate. One end of the connecting rod is hinged to the second hinge shaft, and the other end is provided with a bearing bush that matches the outer ring of the eccentric bearing 8. The swinging drive of the adhesive application mounting frame 4 is achieved through the cooperation of the adjusting motor 7 and the eccentric bearing 8.

[0068] The regulating motor 7 is connected to the eccentric bearing 8 through an adjusting transmission mechanism;

[0069] The adjusting transmission mechanism includes a bushing 9, a transmission shaft 10 fitted inside the bushing 9, a first transmission wheel 11, a second transmission wheel 12, and a transmission belt 13 wrapped around the first transmission wheel 11 and the second transmission wheel 12. The bushing 9 is mounted on the glue-applying lifting frame 3. The first transmission wheel 11 is mounted on the output shaft of the adjusting motor 7, and the second transmission wheel 12 is mounted on one end of the transmission shaft 10. The other end of the transmission shaft 10 is connected to the eccentric bearing shaft of the eccentric bearing 8. This allows the impact force generated by the swinging of the glue-applying mounting plate to be buffered and absorbed by the transmission mechanism, thereby reducing the direct impact and damage to the motor shaft. An adjusting transmission mechanism can also be provided between the adjusting motor 7 and the eccentric bearing 8 to transmit the power of the adjusting motor 7 to the eccentric bearing 8. The remaining structure is the same as in Embodiment 1 or Embodiment 2, and will not be described further here.

[0070] The sheet material is placed on the sheet material support mechanism. Under the action of the glue-spreading walking mechanism, the glue-spreading beam 2 carrying the glue-spreading component 5 can move on the frame 1. The glue-spreading component 5 moves longitudinally to apply glue to the sheet material. Multiple glue-spreading components 5 can be rationally arranged according to the transverse length of the sheet material. For example, the transverse arrangement of multiple glue-spreading components 5 can match the transverse length of the sheet material. The glue-spreading component 5 can complete the glue-spreading operation on the surface of a sheet material in one longitudinal movement or one back-and-forth longitudinal movement. The glue-spreading component 5 can not only move longitudinally, but its height is also adjustable. The height of the glue-spreading component 5 can be adjusted by the glue-spreading lifting mechanism to maintain a suitable glue-spreading height with sheets of different heights. Under the action of the glue-spreading path adjustment mechanism, the glue-spreading component 5 can swing left and right. The glue line can be straight or wavy. The position of the glue line during glue application can move to the left or right, or a wavy glue line can be used to fill the gaps between previous glue lines, thereby improving the bonding quality between adjacent sheets. This utility model has a simple structure, is easy to operate, has high glue-spreading efficiency, and can realize automated glue-spreading operation of sheets, improving the bonding quality of sheets.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
