Specific embodiments

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Refer to Figures 1-6 A PVC sheet gluing device as shown, including a frame 1, on which a transport roller 2 is provided. Two transport rollers 2 are in a group and are rotatably connected to the frame 1. And on the opposite transport rollers 2, there are thread segments with opposite helix directions, and their opposite surfaces are connected by a transmission wheel 3. Multiple groups of transmission wheels 3 are connected by a chain 4. In order to avoid insufficient contact between the middle transmission wheel 3 and the chain 4, resulting in inability to transmit, a guiding rod 6 that pushes the chain 4 upward is provided between two groups of transmission wheels 3 to ensure that the chain 4 drives it. On the outer wall of the frame 1, a transport motor is provided to control the rotation of one group of transport rollers 2 to provide a power source.

[0023] The guiding rod 6 is only half of the width of the entire frame 1, and on the outer wall of the chain 4, there is a pushing member 5 with a T-shaped structure to assist in pushing the object placed on the transport roller 2.

[0024] On the top surface of the frame 1, there is a U-shaped bracket 7, and on the bracket 7, a telescopic cylinder 8 for lifting is installed. At the bottom of the telescopic cylinder 8, there is a nozzle 9, and the nozzle 9 is connected to a glue supply unit to achieve glue spraying operation.

[0025] When the sheet is placed on the transport roller 2, its centering is controlled by the threaded section on the surface of the transport roller 2. With the assistance of the cleaning mechanism 10, the sheet is further centered and positioned, and the overflow glue at the edge is collected.

[0026] Cleaning mechanism 10: The motor 12 is arranged on the outer wall of the bracket 7. An installation seat 11 is provided at the angle between the frame 1 and the bracket 7. The installation seat 11 is a U-shaped part. An adjusting rod 13 is rotatably connected in the slot of the installation seat 11. An adjusting groove 131 is provided on the bottom surface of the free end of the adjusting rod 13. A collecting part 14 for collecting glue is rotatably connected in the adjusting groove 131. A correction mechanism is provided on the adjusting rod 13. When the motor 12 drives the adjusting rod 13 to rotate on the installation seat 11, the correction mechanism adjusts the orientation of the collecting part 14 in the opposite direction, and the collecting part 14 is attached to the sheet.

[0027] Correction mechanism: The mounting plate 15 is installed on the top surface of the adjusting rod 13. A linkage rod 16 is rotatably connected to the mounting plate 15. First gears 17 are provided at both ends of the linkage rod 16. A second gear 18 coaxial with it is provided at the connection of the adjusting rod 13. The second gear 18 is driven by the motor 12, and the second gear 18 meshes with the first gear 17. A third gear 19 coaxial with it is provided at the rotation connection of the collecting part 14. The third gear 19 meshes with the other first gear 17. Thus, through the above structure, when the adjusting rod 13 rotates, the angle of the collecting part 14 is corrected.

[0028] Collecting part 14: The upper part 141 is rotatably connected in the adjusting groove 131, and the upper part 141 is coaxially arranged with the third gear 19. Two symmetric sliding holes 142 are provided on the bottom surface of the upper part 141. A positioning block 143 is provided on the inner wall of the sliding hole 142. The positioning block 143 is hemispherical. A sliding block 146 is provided on the top surface of the collecting hopper 144. The sliding block 146 is provided with a slot adapted to the positioning block 143. The sliding block 146 slides in the sliding hole 142, and the slot and the positioning block 143 cooperate to complete the installation. Scraping glue ports 145 are provided on the opposite surfaces of the collecting hopper 144 to complete the collection of glue.

[0029] As Figure 6 shown, a rectangular convex block is provided at the rear end of the collecting hopper 144, and a slot adapted to the convex block is provided at the rear end of the upper part 141. A screw hole is provided in the slot, and a hole adapted to the screw hole is provided on the convex block. The two are further fixed by bolts.

[0030] The working principle of this utility model: Place the plate on the transport roller 2 of the frame 1, then start the transport motor to drive the transport roller 2 to rotate. The rotating transport roller 2 drives the chain 4 to move through the transmission wheel 3, causing the remaining transmission wheels 3 to rotate accordingly. With the assistance of the guide rod 6, each group of transmission wheels 3 can rotate. With the assistance of the threaded section on the outer wall of the transport roller 2 and the pusher 5 on the chain 4, when transporting the plate, centering is performed. Subsequently, when the glue supply unit is started, the glue is sent into the nozzle 9. The lifting cylinder 8 on the bracket 7 expands and contracts to spray the glue onto the plate. To prevent the glue from overflowing and flowing down from the edge of the plate, start the motor 12 of the cleaning mechanism to drive the adjusting rod 13 on the mounting seat 11 to rotate. During the rotation, the second gear 18 rotates, and by meshing with the first gear 17, it drives the connecting rod 16 to rotate on the mounting plate 15. Furthermore, the first gear 17 at the other end drives the third gear 19 to rotate, causing the collecting member 14 to rotate in the reverse direction within the adjusting groove 131, making the collecting member 14 adhere to the plate.

[0031] After completing the collection of the overflow glue on the plate, the motor 12 rotates in the reverse direction and resets. Subsequently, push the collecting hopper 144 to separate the groove on the slider 146 from the positioning block 143 in the sliding hole 142 of the upper part 141, releasing the limit. Then, the glue that enters the collecting hopper 144 through the glue scraping port 145 is centrally processed and recycled for reuse.

[0032] The electromechanical connection involved in this utility model is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of experiments, belonging to well-known common sense.

[0033] The components not described in detail in this article are prior art.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
