Description

Technical Field

[0001] This utility model relates to the field of leather cushion processing, and in particular to a waterproof adhesive bonding device for leather cushions. Background Technology

[0002] Leather seat cushions are seat upholstery materials commonly used in car seats, sofas, and other furniture. During the manufacturing process, the seams are typically sewn or pieced together, requiring waterproof adhesive to form a seal and prevent moisture from easily penetrating the leather and causing damage or mold.

[0003] Existing leather seat cushions use a bonding device to tightly adhere waterproof adhesive to the leather. During the application of the waterproof adhesive, the leather joint is placed between upper and lower pressure rollers. The rotation of the pressure rollers moves the seat cushion, simultaneously applying the waterproof adhesive to the joint. However, the seat cushion cannot be precisely positioned during movement. If the cushion surface is smooth, the cushion may slip during the movement of the upper and lower pressure rollers, causing the bonding position to shift and resulting in uneven adhesive application. This affects the waterproof performance and shortens the product's lifespan. Utility Model Content

[0004] The main objective of this invention is to provide a waterproof adhesive bonding device for leather seat cushions, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A waterproof adhesive bonding device for leather seat cushions includes a bonding machine with upper and lower pressure rollers. The bonding machine has two sets of support plates. A first mounting groove is formed on one side of each support plate, and several lower positioning rollers are rotatably mounted in the first mounting groove. A mounting plate is positioned directly above the support plate, and a second mounting groove is formed on one side of the mounting plate, within which several upper positioning rollers are rotatably mounted. These upper and lower positioning rollers are aligned with each other. A moving component is provided on the support plate to move the mounting plate. An adjusting component is provided on the bonding machine to adjust the distance between the two sets of support plates.

[0007] As a further embodiment of this utility model, the movable component includes a first fixing plate disposed on one side of the support plate, a first motor being snapped onto one side of the first fixing plate, a first screw being fixedly connected to the output end of the first motor, a second fixing plate disposed on one side of the mounting plate, the first screw being threadedly connected to the second fixing plate, and an anti-detachment plate disposed on the top of the first screw.

[0008] As a further embodiment of this utility model, the adjustment component includes two sets of sliding grooves formed on the bonding machine. The two sets of sliding grooves are symmetrically distributed, and a sliding block is provided in the sliding groove. One end of the sliding block is fixedly connected to one side of the support plate.

[0009] As a further embodiment of this utility model, the adjustment assembly also includes a second motor disposed on one side of the bonding machine, the output end of the second motor being fixedly connected to a second screw, and the second screw being threadedly connected to a set of sliding blocks.

[0010] As a further embodiment of this utility model, one set of the two sets of sliding grooves is connected to a sliding rod, and the sliding rod passes through the sliding block.

[0011] As a further embodiment of this utility model, two sets of connecting plates are fixedly connected to one side of the mounting plate, and a limit rod is provided on one side of each of the two sets of connecting plates.

[0012] As a further embodiment of this utility model, a limiting plate is connected to one side of the support plate, and a slot is provided on the limiting plate, which is adapted to the limiting rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] By using positioning wheels, the leather edges are positioned between two sets of upper and lower positioning wheels. A moving component moves the mounting plate towards the support plate, bringing the upper positioning wheels into contact with the leather. The lower positioning wheels then work together to position the leather edges. As the upper pressure roller moves the leather, the upper and lower positioning wheels continue to position the leather edges, preventing displacement. This solves the problem of seat cushion slippage and misalignment caused by a smooth surface, prevents uneven application of the waterproof adhesive, and ensures unaffected waterproofing performance. This significantly improves product quality and extends its lifespan.

[0015] By inserting a limiting rod into the slot of the limiting plate on one side of the connecting plate, the two sides of the mounting plate are limited to prevent them from shifting when the mounting plate moves, thereby improving the positioning of the positioning wheel on the leather and increasing the practicality of the equipment.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-5 As shown, a waterproof adhesive bonding device for leather seat cushions includes a bonding machine 1. The bonding machine 1 is equipped with an upper pressure roller 2 and a lower pressure roller 3. The bonding machine 1 is equipped with two sets of support plates 4. A first mounting groove 5 is opened on one side of the support plate 4. A plurality of lower positioning rollers 6 are rotatably arranged in the first mounting groove 5. A mounting plate 7 is arranged directly above the support plate 4. A second mounting groove 8 is opened on one side of the mounting plate 7. A plurality of upper positioning rollers 9 are rotatably arranged in the second mounting groove 8. The plurality of upper positioning rollers 9 and the plurality of lower positioning rollers 6 are aligned with each other.

[0024] In this embodiment, a moving component is provided on the support plate 4, which is used to move the mounting plate 7; an adjusting component is provided on the bonding machine 1, which is used to adjust the distance between the two sets of support plates 4.

[0025] When the laminating machine 1 needs to bond waterproof adhesive to leather, it first adjusts the two sets of support plates 4 to a suitable distance according to the size of the leather using the adjusting component. Then, it places the leather joint between the upper pressure roller 2 and the lower pressure roller 3. Next, it places the leather edges between the two sets of upper positioning rollers 9 and lower positioning rollers 6. By moving the component, the mounting plate 7 is moved towards the support plate 4, bonding the upper positioning roller 9 with the leather. The lower positioning roller 6 then positions the leather edges. As the upper pressure roller 2 moves the leather, the upper positioning roller 9, in conjunction with the lower positioning roller 6, positions the leather edges to prevent the leather from shifting. This solves the problem of the cushion sliding and the bonding position shifting due to the smooth surface of the cushion, preventing uneven bonding of the waterproof adhesive layer, thus ensuring that the waterproof performance is not affected, greatly improving product quality, and increasing the product's service life.

[0026] In this embodiment, the moving component includes a first fixing plate 10 disposed on one side of the support plate 4, a first motor 11 snapped onto one side of the first fixing plate 10, a first screw 12 fixedly connected to the output end of the first motor 11, a second fixing plate 13 disposed on one side of the mounting plate 7, the first screw 12 being threadedly connected to the second fixing plate 13, and an anti-detachment plate 14 disposed on the top of the first screw 12.

[0027] The first motor 11 drives the first screw 12 at the output end to rotate. The first screw 12 drives the second fixing plate 13 to move through the thread. The second fixing plate 13 drives the mounting plate 7 to move, moving the upper positioning wheel 9 on the mounting plate 7 to the lower positioning wheel 6, which facilitates positioning of the leather edge and greatly facilitates the operation of the equipment by the workers. The anti-detachment plate 14 prevents the second fixing plate 13 from falling off the first screw 12, increasing the stability of the equipment during use.

[0028] In this embodiment, the adjustment component includes two sets of sliding grooves 15 formed on the laminating machine 1. The two sets of sliding grooves 15 are symmetrically distributed. A sliding block 16 is provided in the sliding groove 15. One end of the sliding block 16 is fixedly connected to one side of the support plate 4. The adjustment component also includes a second motor 18 provided on one side of the laminating machine 1. A second screw 17 is fixedly connected to the output end of the second motor 18. The second screw 17 is threadedly connected to a set of sliding blocks 16.

[0029] The second motor 18 drives the second screw 17 to rotate. The second screw 17 drives the sliding block 16 inside the sliding groove 15 to move through the thread. The sliding block 16 is connected to the bottom of the support plate 4, thereby driving the support plate 4 to slide on the bonding machine 1, which makes it convenient to adjust the spacing of the support plate 4 according to the size of the leather.

[0030] Meanwhile, one set of two sliding grooves 15 is connected to a sliding rod 19, which passes through the sliding block 16. The sliding rod 19 limits the other set of sliding blocks 16 to prevent the support plate 4 from shifting, thereby ensuring that the support plate 4 is adjusted to the appropriate position.

[0031] In this embodiment, two sets of connecting plates 20 are fixedly connected to one side of the mounting plate 7. A limit rod 21 is provided on one side of the two sets of connecting plates 20. A limit plate 22 is connected to one side of the support plate 4. A slot is provided on the limit plate 22, and the slot is adapted to the limit rod 21.

[0032] The limiting rod 21 on one side of the connecting plate 20 is inserted into the slot of the limiting plate 22 to limit the two sides of the mounting plate 7, preventing the two sides from shifting when the mounting plate 7 moves, thereby improving the positioning of the positioning wheel on the leather and increasing the practicality of the equipment.

[0033] It should be noted that this utility model is a waterproof adhesive bonding device for leather cushions. When the bonding machine 1 needs to bond the waterproof adhesive to the leather, the second motor 18 first drives the second screw 17 to rotate. The second screw 17 drives the sliding block 16 inside the sliding groove 15 to move through the thread. The sliding block 16 is connected to the bottom of the support plate 4, thereby driving the support plate 4 to slide on the bonding machine 1. This makes it convenient to adjust the two sets of support plates 4 to a suitable distance according to the size of the leather. Then, the leather connection is placed between the upper pressure roller 2 and the lower pressure roller 3. Then, the leather edge is placed between the two sets of upper positioning rollers 9 and lower positioning rollers 6. The first motor 11 drives the first screw 12 at the output end to rotate. The first screw 12 drives the second fixing plate 13 to move through the thread. The second fixing plate 13 drives the mounting plate 7 to move, bonding the upper positioning roller 9 with the leather. The lower positioning roller 6 positions the leather edge. When the upper pressure roller 2 drives the leather to move, the upper positioning roller 9 and the lower positioning roller 6 position the leather edge to prevent the leather from shifting.
