Description

Technical Field

[0001] This utility model relates to the field of adhesive application device technology, and in particular to a uniform adhesive application device for indoor sofas. Background Technology

[0002] Adhesive application is a crucial process in manufacturing, ensuring the stability of component connections. It is widely used in furniture, building materials, textiles, electronics, and automotive industries. In early production, adhesive application relied on manual brushing and scraping, with operators depending entirely on their experience to control the amount and thickness of adhesive. This not only made it difficult to guarantee uniform application, leading to inconsistent bonding strength, peeling, bubbling, and other quality issues, but also proved unsuitable for large-scale production. With the transformation of industry towards large-scale operations, market demands for consistent product quality, coupled with rising labor costs, have created a need for automated equipment to achieve precise adhesive application, balancing quality and efficiency.

[0003] Existing traditional fabric coating equipment is mostly designed for fixed widths, resulting in poor adaptability. When processing fabrics of different widths, the entire coating template must be replaced, or the equipment must be manually disassembled and adjusted. This adjustment method is cumbersome, difficult to operate, and time-consuming, affecting the overall production efficiency of fabric coating. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a uniform adhesive coating device for indoor sofas.

[0005] This utility model is achieved by the following technical solution: a uniform adhesive application device for indoor sofa fabric, including a sofa fabric driving device, an adhesive application adjustment component is provided on the top of the sofa fabric driving device, and auxiliary components are provided on both sides of the adhesive application adjustment component.

[0006] The adhesive application adjustment assembly includes a support block, a fixing block fixedly connected to the top of the support block, a drive motor fixedly connected to the top of the fixing block, a motor rotating rod fixedly connected to the output end of the drive motor, a bevel gear fixedly connected to the outer wall of the motor rotating rod, a driven bevel gear meshing with the outer wall of the bevel gear, a bidirectional threaded rod fixedly connected to the inner wall of the driven bevel gear, a threaded slider threadedly connected to the outer wall of the bidirectional threaded rod, an adhesive application barrier plate in contact with the front of the support block, a connecting bolt in contact with the inner wall of the adhesive application barrier plate, the connecting bolt penetrating the inner wall of the adhesive application barrier plate and extending therefrom, an adhesive application adjustment plate in contact with the front of the threaded slider, a fixing bolt in contact with the inner wall of the adhesive application adjustment plate, the fixing bolt penetrating the inner wall of the adhesive application adjustment plate and extending therefrom, and an adhesive application guide block fixedly connected to the front of the support block.

[0007] As a further improvement to the above solution, the two ends of the bidirectional threaded rod are rotatably connected to the inner wall of the support block, the outer wall of the threaded slider is slidably connected to the surface of the support block, one end of the connecting bolt that passes through the glued barrier plate is threaded to the inner wall of the support block, and one end of the fixing bolt that passes through the glued adjustment plate is threaded to the inner wall of the threaded slider.

[0008] As a further improvement to the above solution, two fixing blocks are provided, which are symmetrically arranged with the motor rotating rod as the center, and two threaded sliders are provided, which are symmetrically arranged with the motor rotating rod as the center.

[0009] As a further improvement to the above solution, two connecting bolts are provided, and the two connecting bolts are symmetrically arranged with the drive motor as the center. Two glue application adjusting plates are provided, and the two glue application adjusting plates are symmetrically arranged with the drive motor as the center.

[0010] Through the above technical solution, the fixed block at the top of the support block provides a stable installation base for the drive motor. After the drive motor is running, its output end drives the motor rotating rod to rotate, and the motor rotating rod in turn drives the bevel gear fixed on the outer wall to rotate synchronously. Through the meshing of the bevel gear and the driven bevel gear, the power is transmitted to the bidirectional threaded rod fixed on the inner wall of the driven bevel gear.

[0011] As a further improvement to the above solution, the auxiliary component includes a T-shaped slide groove, which is formed on the inner wall of the sofa fabric drive device. A T-shaped slider is slidably connected to the inner wall of the T-shaped slide groove, and the T-shaped slider is fixedly connected to the right side of the support block.

[0012] As a further improvement to the above solution, two T-shaped slides are provided, and the two T-shaped slides are symmetrically arranged with the drive motor as the center. Two T-shaped sliders are provided, and the two T-shaped sliders are symmetrically arranged with the drive motor as the center.

[0013] As a further improvement to the above solution, the inner wall of the T-shaped slider is threaded with an adjusting screw, the outer wall of the adjusting screw is rotatably connected to the inner wall of the sofa fabric driving device, the top of the adjusting screw penetrates through the inner wall of the sofa fabric driving device and extends therefrom, and the top of the adjusting screw is fixedly connected with an adjusting handle.

[0014] As a further improvement to the above solution, a fixed base is fixedly connected to the top of the sofa fabric driving device, and a connecting bolt 2 is provided in contact with the inner wall of the fixed base. The outer wall of the connecting bolt 2 is threadedly connected to the inner wall of the sofa fabric driving device. A support shaft is fixedly connected to the top of the fixed base, and a rotating rod is rotatably connected to the inner wall of the support shaft. A fabric grinding wheel is fixedly connected to the end of the rotating rod away from the support shaft.

[0015] With the above technical solution, a T-shaped groove is formed on the inner wall of the sofa fabric drive device. The T-shaped slider, which is slidably connected inside, is fixed to the right side of the support block, providing an adjustment base for the glue application adjustment component. Then, rotating the adjustment handle can drive the adjustment screw to rotate on the inner wall of the sofa fabric drive device. Since the adjustment screw is threadedly connected to the T-shaped slider, it drives the T-shaped slider to slide up and down along the T-shaped groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a stable mounting base for the drive motor via a fixed block at the top of the support block. When the drive motor is running, its output drives the motor rotating rod to rotate, which in turn drives the bevel gear fixed to the outer wall to rotate synchronously. Through the meshing of the bevel gear and the driven bevel gear, power is transmitted to the bidirectional threaded rod fixed to the inner wall of the driven bevel gear, causing the bidirectional threaded rod to rotate on the inner wall of the support block. When the bidirectional threaded rod rotates, two threaded sliders connected to its outer wall slide relative to or towards each other along the surface of the support block. These threaded sliders, via fixing bolts, drive the glue-applying adjustment plates to move synchronously, thus flexibly adjusting the distance between the two glue-applying adjustment plates to accommodate the glue application needs of indoor sofa fabrics of different widths. Furthermore, the glue-applying barrier plate, fixed to the front of the support block by two symmetrically arranged connecting bolts, prevents glue from overflowing to both sides, limiting the glue application area. The glue-applying guide block fixed to the front of the support block provides guidance for the glue supply, further ensuring the uniformity of glue application to the sofa fabric in conjunction with the glue-applying adjustment plates. The two fixed blocks, two threaded sliders, and two glue application adjustment plates are all symmetrically arranged with the motor rotation rod or drive motor as the center to ensure balanced power transmission, smooth glue application adjustment process, and avoid unilateral deviation affecting the glue application effect.

[0017] This invention utilizes a T-shaped groove formed on the inner wall of the sofa fabric drive device. An internally slidably connected T-shaped slider is fixed to the right side of the support block, providing an adjustment base for the adhesive application adjustment assembly. Rotating the adjustment handle drives the adjustment screw to rotate within the sofa fabric drive device. Since the adjustment screw is threadedly connected to the T-shaped slider, it drives the T-shaped slider to slide up and down along the T-shaped groove, simultaneously adjusting the height of the support block and the entire adhesive application adjustment assembly. This adapts to the adhesive application requirements of sofa fabrics of different thicknesses. The two T-shaped grooves and two T-shaped sliders are symmetrically arranged around the drive motor, ensuring balanced force on the adhesive application adjustment assembly during vertical movement, preventing tilting and ensuring adhesive application accuracy. The fixed base is fixed to the top of the sofa fabric drive device by connecting bolts, and its top support shaft provides rotational support for the rotating rod. The fabric roller fixed at one end of the rotating rod is specifically designed to transport the edges of the glued fabric. It can smoothly guide the glued fabric forward, preventing damage to the edge adhesive layer due to adhesion or displacement of the fabric. It can also help keep the edges of the fabric neat, ensuring the continuity of subsequent processing. Attached Figure Description

[0021] Example: Please combine Figure 1-5 This embodiment provides a uniform adhesive application device for indoor sofa fabric, including a sofa fabric driving device 1, an adhesive application adjustment component 2 on the top of the sofa fabric driving device 1, and auxiliary components 3 on both sides of the adhesive application adjustment component 2.

[0022] The adhesive application adjustment assembly 2 includes a support block 201, a fixing block 202 fixedly connected to the top of the support block 201, a drive motor 203 fixedly connected to the top of the fixing block 202, a motor rotating rod 204 fixedly connected to the output end of the drive motor 203, a bevel gear 205 fixedly connected to the outer wall of the motor rotating rod 204, a driven bevel gear 206 meshing with the outer wall of the bevel gear 205, a bidirectional threaded rod 207 fixedly connected to the inner wall of the driven bevel gear 206, and a threaded connection to the outer wall of the bidirectional threaded rod 207.

When the bidirectional threaded rod 207 rotates, the two threaded sliders 208 connected to its outer wall slide relative to or towards each other along the surface of the support block 201. The threaded sliders 208 drive the glue-applying adjustment plates 211 to move synchronously through the fixing bolts 212, thereby flexibly adjusting the distance between the two glue-applying adjustment plates 211 to adapt to the glue application needs of indoor sofa fabrics of different widths.

[0026] The auxiliary component 3 includes a T-shaped slide 301, which is formed on the inner wall of the sofa fabric drive device 1. A T-shaped slider 302 is slidably connected to the inner wall of the T-shaped slide 301, and the T-shaped slider 302 is fixedly connected to the right side of the support block 201.

[0027] Two T-shaped slides 301 are provided, and the two T-shaped slides 301 are symmetrically arranged with the drive motor 203 as the center. Two T-shaped sliders 302 are provided, and the two T-shaped sliders 302 are symmetrically arranged with the drive motor 203 as the center.

[0028] The inner wall of the T-shaped slider 302 is threaded with an adjusting screw 303. The outer wall of the adjusting screw 303 is rotatably connected to the inner wall of the sofa fabric drive device 1. The top of the adjusting screw 303 passes through the inner wall of the sofa fabric drive device 1 and extends thereto. An adjusting handle 304 is fixedly connected to the top of the adjusting screw 303.

[0029] A fixed base 305 is fixedly connected to the top of the sofa fabric drive device 1. A connecting bolt 306 is installed on the inner wall of the fixed base 305, and the outer wall of the connecting bolt 306 is threaded to the inner wall of the sofa fabric drive device 1. A support shaft 307 is fixedly connected to the top of the fixed base 305. A rotating rod 308 is rotatably connected to the inner wall of the support shaft 307. A fabric grinding wheel 309 is fixedly connected to the end of the rotating rod 308 away from the support shaft 307. The support shaft 307 at the top provides rotational support for the rotating rod 308. The fabric grinding wheel 309 fixed to one end of the rotating rod 308 is specifically designed to transport the edge of the sofa fabric after applying adhesive. It can smoothly guide the fabric after applying adhesive forward and prevent the edge adhesive layer from being damaged due to adhesion or displacement of the fabric.

[0030] The implementation principle of the uniform adhesive application device for indoor sofa fabric in this embodiment is as follows: A fixed block 202 at the top of the support block 201 provides a stable mounting base for the drive motor 203. After the drive motor 203 is running, its output end drives the motor rotating rod 204 to rotate. The motor rotating rod 204 then drives the bevel gear 205 fixed on the outer wall to rotate synchronously. Through the meshing of the bevel gear 205 and the driven bevel gear 206, power is transmitted to the bidirectional threaded rod 207 fixed on the inner wall of the driven bevel gear 206, causing the bidirectional threaded rod 207 to rotate on the inner wall of the support block 201. When the bidirectional threaded rod 207 rotates, two threaded sliders 208 connected by threads on its outer wall slide relative to or towards each other along the surface of the support block 201. The threaded sliders 208 drive the adhesive application adjusting plate 211 to move synchronously through the fixing bolt 212, thereby flexibly adjusting the distance between the two adhesive application adjusting plates 211 to adapt to the adhesive application needs of indoor sofa fabrics of different widths. The adhesive blocking plate 209 is fixed to the front of the support block 201 by two symmetrically arranged connecting bolts 210, which can prevent the adhesive from overflowing to both sides and limit the adhesive application range. The adhesive guide block 213 fixed to the front of the support block 201 provides guidance for the supply of adhesive, and together with the adhesive adjustment plate 211, further ensures the uniformity of adhesive application to the sofa fabric. The two fixed blocks 202, the two threaded sliders 208, and the two adhesive adjustment plates 211 are all symmetrically arranged with the motor rotating rod 204 or the drive motor 203 as the center, ensuring balanced power transmission, smooth adhesive adjustment process, and avoiding unilateral deviation that affects the adhesive application effect. In addition, a T-shaped slide groove 301 is opened in the inner wall of the sofa fabric drive device 1, and the T-shaped slider 302 slidably connected inside is fixed to the right side of the support block 201, providing an adjustment base for the adhesive adjustment assembly 2. Then, rotating the adjustment handle 304 causes the adjustment screw 303 to rotate on the inner wall of the sofa fabric drive device 1. Since the adjustment screw 303 is threadedly connected to the T-shaped slider 302, it drives the T-shaped slider 302 to slide up and down along the T-shaped groove 301, simultaneously driving the support block 201 and the entire glue application adjustment assembly 2 to adjust the height, thus adapting to the glue application requirements of sofa fabrics of different thicknesses. The two T-shaped grooves 301 and the two T-shaped sliders 302 are symmetrically arranged with the drive motor 203 as the center, ensuring that the glue application adjustment assembly 2 is subjected to balanced force during up and down movement, avoiding tilting and offset, and ensuring glue application accuracy. The fixed base 305 is fixed to the top of the sofa fabric drive device 1 by connecting bolt 306, and the support shaft 307 at its top provides rotational support for the rotating rod 308. The fabric roller 309, fixed at one end of the rotating rod 308, is specifically designed to transport the edges of the fabric after gluing. It can smoothly guide the fabric after gluing forward, preventing damage to the edge adhesive layer due to adhesion or displacement of the fabric after gluing. It can also help keep the edges of the fabric neat and ensure the continuity of subsequent processing.
