Description

Technical Field

[0001] This application relates to the field of fabric production technology, and in particular to a production line for combining synthetic leather and fabric. Background Technology

[0002] In the production process of automotive interiors, synthetic leather and fabric need to be bonded together, and then the bonded mixed fabric is conveyed to an oven for drying.

[0003] When bonding synthetic leather and fabric, glue needs to be added between the two materials. The glued fabric and synthetic leather are then passed between two compaction rollers. However, when the two compaction rollers bond the synthetic leather and fabric, excess glue may overflow and adhere to the roller surface. Because the rollers are rotating, glue from the roller surface may seep into the synthetic leather / fabric surface, thus affecting product quality. Summary of the Invention

[0004] In order to reduce the amount of adhesive adhering to the surface of the compaction roller from entering the surface of synthetic leather / fabric, this application provides a synthetic leather / fabric bonding production line.

[0005] The synthetic leather fabric combination production line provided in this application adopts the following technical solution:

[0006] A synthetic leather fabric bonding production line includes a frame and a bonding station disposed on the frame. The bonding station includes a bonding frame mounted on the frame, two pressure rollers rotatably mounted on the bonding frame, and a cleaning component mounted on the bonding frame. The fabric and synthetic leather are passed between the two pressure rollers.

[0007] The cleaning assembly includes a first scraper, a second scraper, and a driving component. The first scraper is inclinedly disposed on the adhesive frame and abuts against the pressure roller. A collection box for collecting adhesive is provided at the end of the first scraper away from the pressure roller. The second scraper is slidably mounted on the upper surface of the first scraper, and the driving component is used to drive the second scraper to slide.

[0008] By adopting the above technical solution, the first scraper abuts against the outer wall of the pressing roller, which can scrape off the glue on the surface of the pressing roller, reducing the amount of glue on the surface of the pressing roller from entering the surface of the synthetic leather / fabric, thus maintaining product quality; while the second scraper slides on the surface of the first scraper under the drive of the drive component, which can scrape the glue on the surface of the first scraper toward one side of the collection box and scrape it into the collection box; thus cleaning the glue on the surface of the first scraper in a timely manner, reducing the possibility of glue solidifying on the surface of the first scraper, and maintaining the cleaning effect of the first scraper on the surface of the pressing roller.

[0009] Optionally, the driving components are provided in two sets, both sets of driving components are disposed on the first scraper and spaced apart along the extension direction of the pressure roller; the driving components include multiple conveying rollers rotatably mounted on the first scraper, a conveyor belt wrapped around the surface of all the conveying rollers, and a driving member that drives the conveying rollers to rotate, and the two ends of the second scraper are respectively connected to the conveyor belts of the two driving components.

[0010] By adopting the above technical solution, when the drive unit drives the conveyor roller to rotate, the conveyor belt can be conveyed on the first scraper; when the connection point between the conveyor belt and the second scraper is below the conveyor roller, the second scraper abuts against the surface of the first scraper to scrape off the glue on the surface of the first scraper; and when the second scraper is conveyed to the end of the conveyor belt away from the pressure roller, the second scraper moves toward the side away from the first scraper and there is a gap between the second scraper and the first scraper to reduce the situation where the glue is brought to the pressure roller when the second scraper moves toward the side of the pressure roller and returns to its original state.

[0011] Optionally, the outer wall of the second scraper is fitted with a cleaning housing, the side wall of the cleaning housing is provided with a guide rod, and the first scraper is provided with a sliding channel for the guide rod to slide, the extension direction of the sliding channel is in the same direction as the sliding direction of the second scraper.

[0012] By adopting the above technical solution, during the movement of the guide rod in the sliding channel, the second scraper slides on the upper surface of the first scraper and moves toward one side of the collection box; and when the connection between the second scraper and the conveyor belt is transmitted from below the conveyor roller to above the conveyor roller, since the guide rod is slidably installed in the sliding channel, the second scraper can slide in the cleaning housing, so that the cleaning housing scrapes off the glue on the surface of the second scraper, thereby maintaining the cleaning effect of the second scraper on the surface of the first scraper.

[0013] Optionally, the end of the sliding channel away from the pressure roller is provided with a pressing plate for abutting against the outer wall of the cleaning housing, and a cleaning plate is slidably installed on the bottom wall of the pressing plate; the pressing plate is provided with a reversing member, and when the cleaning housing abuts against the pressing plate, the reversing member is used to drive the cleaning plate to abut against the bottom wall of the cleaning housing.

[0014] By adopting the above technical solution, when the second scraper moves toward the side of the abutment plate and abuts against the abutment plate, the cleaning plate moves toward the side of the cleaning housing and abuts against the bottom wall of the cleaning housing. The cleaning plate can clean the glue on the bottom of the cleaning housing, further improving the cleaning effect on the glue on the surface of the second scraper.

[0015] Optionally, the reversing component includes a support seat mounted on the side of the abutment plate away from the cleaning housing, a rotating rod rotatably mounted on the support seat, and a reversing block slidably mounted on the abutment plate. Telescopic rods are movably mounted at both ends of the rotating rod, and the two telescopic rods are respectively hinged to the abutment plate and the cleaning plate.

[0016] By adopting the above technical solution, when the reversing block abuts against the cleaning housing and pushes the reversing block toward the side away from the pressure roller, the telescopic rods at both ends of the rotating rod are hinged to the reversing block and the cleaning plate respectively, which can drive the rotating rod to rotate on the support base; thereby causing the cleaning plate to move toward the cleaning housing and clean the glue at the bottom of the cleaning housing.

[0017] Optionally, the inner wall of the cleaning housing is provided with a rubber layer for abutting against the outer wall of the second scraper.

[0018] By adopting the above technical solution and setting a rubber layer, the friction between the cleaning housing and the second scraper can be increased, thereby improving the cleaning effect of the cleaning housing on the adhesive on the outer wall of the second scraper.

[0019] Optionally, the adhesive frame is provided with a sliding rod, and the first scraper is provided with a mounting sleeve for fitting onto the outer wall of the sliding rod, the mounting sleeve being fixed to the sliding rod by a fastener.

[0020] By adopting the above technical solution, the contact position between the first scraper and the pressure roller can be changed according to the size of the fabric by sliding the first scraper onto the sliding rod, thereby improving the cleaning effect of the first scraper on the adhesive on the surface of the pressure roller.

[0021] Optionally, the fixing component is configured as a screw, the mounting sleeve has a threaded hole, and the screw is threadedly installed in the threaded hole and abuts against the outer wall of the sliding rod.

[0022] By adopting the above technical solution, and by setting the fixing component as a screw, which rotates within a threaded hole to abut against the outer wall of the sliding rod, the free slippage of the mounting sleeve on the sliding rod can be reduced, thus achieving the fixation of the mounting sleeve on the sliding rod. Furthermore, the screw structure is simple and inexpensive, reducing production costs.

[0023] Optionally, the cleaning components are provided in two sets, and both sets of the cleaning components are installed on the sliding rod; the sliding rod has a rectangular cross-section, and the fixing component includes a gear, a telescopic component, and two racks, the two racks being connected to two mounting sleeves respectively; the gear is rotatably installed on the sliding rod through the telescopic component, and both racks mesh with the gear; the sliding rod has a toothed groove for the gear to be inserted.

[0024] By adopting the above technical solution, by disengaging the gear from the tooth groove and rotating it, the two racks can mesh with the gear, allowing the two mounting sleeves connected to the two racks to move closer to or further away from each other; thereby simultaneously adjusting the position of the two first scrapers so that the two first scrapers can clean the glue adhering to both ends of the pressure roller, further improving work efficiency.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] Example 1:

[0036] Embodiment 1 of this application discloses a production line for combining synthetic leather and fabric.

[0037] Reference Figure 1 A synthetic leather fabric bonding production line includes a frame 1, a bonding station 4 installed on the frame 1, a fabric conveying station 2, and a synthetic leather conveying station 3. The fabric conveying station 2 includes a first motor 23, a first driving roller 21, and a first driven roller 22. The first driving roller 21 and the first driven roller 22 are rotatably mounted on the frame 1. The fabric passes through the first driving roller 21 and the first driven roller 22. The first motor 23 is used to drive the first driving roller 21 to rotate in order to convey the fabric.

[0038] The synthetic leather conveying station 3 includes a second driving roller 31, a second driven roller 32, and a second motor 33. The second driven roller 32 and the second rotating roller are both rotatably mounted on the frame 1. The synthetic leather passes between the second driving roller 31 and the second driven roller 32. The second motor 33 is used to drive the second driving roller 31 to rotate in order to convey the synthetic leather.

[0039] In this embodiment, the conveying direction of synthetic leather at the synthetic leather conveying station 3 is opposite to that of fabric at the fabric conveying station 2, so as to make the structure of the production line more compact; the frame 1 is provided with a reversing roller 11, which is used to change the conveying direction of the fabric to facilitate the bonding of synthetic leather and fabric.

[0040] The frame 1 is equipped with a feeding pipe 12, which has multiple feeding holes for adding glue to the surface of synthetic leather. One end of the feeding pipe 12 is connected to an external feeding device.

[0041] The bonding station includes a bonding frame 41, a cleaning component 42, and two pressure rollers 43. The bonding frame 41 is mounted on the frame 1 and located at the rear end of the conveying direction of the reversing roller 11. Both pressure rollers 43 are rotatably mounted on the bonding frame 41, and the bonding frame 41 is equipped with a third motor 49 for driving one of the pressure rollers 43 to rotate. Synthetic leather and fabric are passed between the two pressure rollers 43 for clamping and bonding.

[0042] Reference Figure 2 The cleaning assembly 42 is provided in four sets, with each pair of cleaning assemblies 42 respectively located at both ends of the two pressing rollers 43; the bonding frame is provided with two sliding rods 44, with each pair of cleaning assemblies 42 respectively mounted on the two sliding rods 44. The cleaning assembly 42 includes a first scraper 421, a second scraper 422, and a driving component 423. The bottom of the first scraper 421 is provided with a mounting sleeve 45, and the sliding rods 44 pass through the mounting sleeve 45. The mounting sleeve 45 is fixed to the sliding rods 44 by a fastener 47.

[0043] In this embodiment, the fixing member 47 is set as a screw 471, and the sliding rod 44 is slidably installed in the threaded hole 46. The screw 471 is threadedly installed in the threaded hole 46 and abuts against the outer wall of the sliding rod 44. When the size of the fabric changes, the abutment between the screw 471 and the outer wall of the sliding rod 44 is canceled to change the connection position between the first scraper 421 and the sliding rod 44.

[0044] One end of the first scraper 421 is inclinedly disposed on the surface of the pressing roller 43, and a collection box 428 is disposed at the end of the first scraper 421 away from the pressing roller 43; the first scraper 421 can scrape off the glue on the surface of the pressing roller 43, and the glue flows on the inclined first scraper 421 into the collection box 428 for centralized processing of the glue.

[0045] Two sets of drive components 423 are provided, each set being disposed on the first scraper 421 and spaced apart along the extension direction of the pressure roller 43. Each drive component 423 includes two conveyor rollers 424, a conveyor belt 425 wrapped around the surface of the two conveyor rollers 424, and a drive member 426 for driving the conveyor rollers 424 to rotate. The first scraper 421 is provided with a mounting frame 427, and the conveyor rollers 424 are rotatably mounted on the mounting frame 427. In this embodiment, the drive member 426 is configured as a fourth motor, which is mounted on the mounting frame 427 and connected to one of the conveyor rollers 424. The conveying direction of the conveyor belt 425 is the same as the extension direction of the first scraper 421. The second scraper 422 abuts against the upper surface of the first scraper 421, and both ends of the second scraper 422 are respectively connected to the sides of the conveyor belts 425 of the two conveyor components that are close to each other.

[0046] A cleaning housing 5 is fitted onto the outer wall of the second scraper 422, and a rubber layer 51 is provided between the cleaning housing 5 and the second scraper 422. Guide rods 52 are provided at opposite ends of the cleaning housing 5, and sliding channels 48 are provided on both sides of the first scraper 421. The guide rods 52 are slidably installed in the sliding channels 48. When the second scraper 422 moves away from the first scraper 421 to cancel its contact with the first scraper 421, the guide rods 52, located in the sliding channels 48, allow the second scraper 422 to slide within the cleaning housing 5, so that the cleaning housing 5 scrapes off the glue adhering to the surface of the second scraper 422, maintaining the cleaning effect of the second scraper 422 on the first scraper 421.

[0047] Reference Figure 3 A retaining plate 6 is provided on the side of the sliding channel 48 near the collection box 428. The retaining plate 6 is used to abut against the side wall of the cleaning housing 5. A cleaning plate 61 is slidably installed on the retaining plate 6, and the cleaning plates 61 on both sides of the first scraper 421 are connected by a connecting plate 62. The connecting plate 62 is used to abut against the bottom wall of the cleaning housing 5, and can clean up the glue scraped off the bottom wall of the cleaning housing 5.

[0048] The pressing plate 6 is provided with a reversing component 63, which includes a support base 64, a rotating rod 65, and a reversing block 66. The pressing plate 6 has a reversing hole 69, and the reversing block 66 is slidably installed in the reversing hole 69. The support base 64 is fixed to the side of the pressing plate 6 away from the pressure roller 43, and the rotating rod 65 is rotatably installed in the support base 64. The rotating rod 65 has telescopic grooves 67 at opposite ends, and telescopic rods 68 are slidably installed in the telescopic grooves 67. The two telescopic rods 68 are rotatably connected to the reversing block 66 and the end of the cleaning plate 61 away from the pressure roller 43, respectively.

[0049] In this embodiment, a torsion spring 641 is provided between the rotating rod 65 and the support base 64. The elastic force of the torsion spring 641 is used to force the reversing block 66 to move toward the side of the pressure roller 43, that is, the elastic force of the torsion spring 641 can force the cleaning plate 61 to move toward the side away from the pressure roller 43.

[0050] When the connection between the second scraper 422 and the conveyor belt 425 is transmitted from below the conveyor roller 424 to above the conveyor roller 424, the cleaning housing 5 abuts against the reversing block 66 and pushes the reversing block 66 toward the side away from the pressure roller 43; since the telescopic rods 68 at both ends of the rotating rod 65 are hinged to the reversing block 66 and the cleaning plate 61 respectively, the rotating rod 65 can be driven to rotate on the support 64, thereby causing the cleaning plate 61 to move toward the cleaning housing 5 and clean the glue at the bottom of the cleaning housing 5.

[0051] The implementation principle of a synthetic leather fabric combined production line in Embodiment 1 of this application is as follows:

[0052] The first scraper 421 abuts against the outer wall of the pressing roller 43, which can scrape off the glue on the surface of the pressing roller 43, reducing the amount of glue on the surface of the pressing roller from entering the surface of the synthetic leather / fabric, thus maintaining product quality. The second scraper 422 slides on the surface of the first scraper 421 under the transmission of the conveyor belt 425, which can scrape the glue on the surface of the first scraper 421 toward the side of the collection box 428 and scrape it into the collection box 428. This timely cleaning of the glue on the surface of the first scraper 421 reduces the possibility of glue solidification on the surface of the first scraper 421 and maintains the cleaning effect of the first scraper 421 on the surface of the pressing roller 43.

[0053] Furthermore, when the second scraper 422 moves back toward the side of the pressure roller 43, the connection between the second scraper 422 and the conveyor belt 425 is moved above the conveyor roller 424, which allows a gap to exist between the second scraper 422 and the first scraper 421, reducing the possibility that the second scraper 422 will push the glue on the surface of the first scraper 421 to the side of the pressure roller 43.

[0054] Example 2:

[0055] Embodiment 2 of this application discloses a production line for combining synthetic leather and fabric.

[0056] Reference Figure 4 and Figure 5The difference between Embodiment 2 and Embodiment 1 is that: the sliding rod 44 has a rectangular cross-section, the fixing member 47 includes a gear 472, a telescopic member 474 and two racks 473, the telescopic member 474 includes a movable sleeve 476, a movable rod 475 movably installed in the movable sleeve 476 and a spring 477 disposed between the movable rod 475 and the movable sleeve 476; the upper surface of the sliding rod 44 has a toothed groove 441, the movable sleeve 476 is rotatably installed in the toothed groove 441, the gear 472 is fixed to the end of the movable rod 475 away from the movable sleeve 476, and the elastic force of the spring 477 is used to drive the gear 472 to be inserted into the toothed groove 441.

[0057] Reference Figure 4 In this embodiment, a guide block 478 is provided on the outer wall of the movable rod 475, and a guide groove 479 is provided on the inner wall of the movable sleeve 476 for the guide block 478 to slide. The cooperation between the guide block 478 and the guide groove 479 can reduce the rotation between the movable rod 475 and the movable sleeve 476.

[0058] Two racks 473 are respectively fixed to two mounting sleeves 45 on the sliding rod 44, and both racks 473 mesh with gears 472. By rotating the gears 472, the two mounting sleeves 45 connected to the two racks 473 can be moved closer or further apart, so that the two first scrapers 421 can clean the glue adhering to both ends of the pressure roller 43; and after the position of the first scrapers 421 is adjusted, the gears 472 are inserted into the tooth grooves 441, which can fix the two mounting sleeves 45 to the sliding rod 44.

[0059] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
