A leather processing device for seat processing

Abstract

One or more embodiments of the present specification provide a leather processing device for seat processing. During embossing, the area to be embossed is transferred to the upper end of the receiving plate, and the leather to be embossed passes through the clamping box from four clamping holes at the same time. The electric telescopic rod is extended and moves downward, driving the end of the first traction rope to move downward through the embossing plate, and the first traction rope pulls the double-sided rack to move toward the side wall of the processing box. The double-sided rack drives the opposite sides of the meshing clamping gears to rotate toward the side wall of the processing box, and drives the clamping shaft to rotate in the opposite direction, so that the two clamping plates rotate and contact the leather. Under the action of friction, the opposite sides of the two clamping plates tend to move toward the side wall of the processing box, so that the leather between the two clamping boxes is tightened to eliminate wrinkles, to prevent pressing on wrinkles during embossing, resulting in unclear embossing or the scrapping of the entire piece of leather, thereby improving the working stability of the leather processing device for seat processing.

Description

Technical Field

[0001] One or more embodiments of the present specification relate to the technical field of seat processing, and in particular, to a leather processing device for seat processing. Background Art

[0002] Car seats need to go through multiple processing steps during production. Among them, leather seats usually need to be embossed with the manufacturer's name or other identifying words before wrapping the seat body. Existing leather processing equipment for seat processing usually presses the words directly on the seat leather by mechanical means.

[0003] However, the inventors found that the existing leather processing devices for seat processing emboss the leather by placing the leather on a panel and then directly embossing the leather. However, the inventors found that the existing embossing method easily causes wrinkles on the leather panel. If the embossing is pressed on the wrinkles, it will cause unclear embossing or even the entire piece of leather to be scrapped, which greatly affects the working stability of the leather processing devices for seat processing.

[0029] Based on the above purpose, one or more embodiments of this specification provide a leather processing device for seat processing, characterized in that it includes:

[0030] A processing box 1, in which a top plate 2 is fixedly arranged, and the two ends of the top plate 2 are fixed on the two opposite side walls of the processing box 1, and an embossed plate 4 is connected to the bottom end surface of the top plate 2 through an electric telescopic rod 3, and two first transfer pulleys 5 are respectively arranged at the two ends of the top plate 2, and a second transfer gear is arranged at the lower side of the side wall of the processing box 1 opposite to each first transfer pulley 5, and two first traction ropes 7 are respectively connected to the top of the embossed plate 4 on both sides of the electric telescopic rod 3, and the first traction ropes 7 are wound around the first transfer pulley 5 and the second transfer pulley 6 on the same side;

[0031] Conveying roller 8, two mutually parallel conveying rollers 8 are arranged on both sides of the lower side of the top plate 2, two clamping boxes 9 are arranged between the two conveying rollers 8 and close to the two conveying rollers 8, and two horizontal strip-shaped clamping holes 10 of the same height as the top side of the conveying roller 8 are respectively opened on the opposite side walls of each clamping box 9, and two clamping shafts 11 penetrating the clamping box 9 are rotatably arranged on the upper and lower sides of the clamping holes 10 in the clamping box 9, and arc-shaped clamping pieces 12 are arranged on the clamping shafts 11 along the length direction, and the ends of the two clamping shafts 11 of the same clamping box 9 on the same side pass through the clamping box 9 and are respectively fixed with two clamping gears 13, and a double-sided rack 14 is meshed between the two clamping gears 13 at the same time, and the ends of the double-sided rack 14 close to the conveying roller 8 on the same side are connected to the tail end of the first traction rope 7 on the same side;

[0032] The receiving plate 15 is arranged directly below the embossed plate 4 and the upper end surface thereof corresponds in height to the clamping hole 10 . The bottom end of the receiving plate 15 is fixedly connected to the bottom end of the processing box 1 through a plurality of support rods 16 .

[0033] One or more embodiments of the present specification provide a leather processing device for seat processing, which transmits the leather to be embossed on two conveying rollers 8, and transmits the area to be embossed to the upper end of the receiving plate 15 during embossing, and the leather to be embossed passes through the clamping box 9 from the four clamping holes 10 at the same time, and the electric telescopic rod 3 extends and moves downward, driving the end of the first traction rope 7 to move downward through the embossing plate 4, and the first traction rope 7 pulls the double-sided rack 14 toward the side wall of the processing box 1, and the double-sided rack 14 drives the opposite sides of the meshing clamping gear 13 to rotate toward the side wall of the processing box 1, and drives the clamping shaft 11 to rotate in the opposite direction, so that the two clamping plates 12 rotate and contact the leather, and under the action of friction, the opposite sides of the two clamping plates 12 tend to move toward the side wall of the processing box 1, so that the leather between the two clamping boxes 9 is tightened to eliminate wrinkles, to prevent pressing on wrinkles during embossing, resulting in unclear embossing or the scrapping of the entire piece of leather, thereby improving the working stability of the leather processing device for seat processing.

[0034] As an optional implementation, both ends of the rotating shaft of the conveying roller 8 are connected to a rotating frame 17 , and the bottom end of the rotating frame 17 is fixed to the bottom side wall of the processing box 1 .

[0035] As an optional implementation, the length of the clamping hole 10 is greater than the length of the conveying roller 8 .

[0036] The leather to be embossed is conveyed by two conveying rollers 8 for continuous embossing. The length of the clamping hole 10 is greater than that of the conveying rollers 8 so that the clamping hole 10 can adapt to the passage of leathers of different widths.

[0037] As an optional embodiment, the clamping piece 12 corresponds to the curvature of the clamping shaft 11 and is bent along the side of the clamping shaft 11. An adjusting screw hole is opened on the clamping shaft 11, and an adjusting bolt 18 is threaded in the adjusting screw hole. A rotating disk 19 is fixed to one end of the adjusting bolt 18 facing the inner side of the clamping piece 12, and a rotating cover 20 is fixed to the corresponding position on the inner side of the clamping piece 12. The adjusting bolt 18 passes through the rotating cover 20 and the rotating disk 19 is rotatably set in the rotating cover 20.

[0038] When the embossing plate 4 is not pressed down, the two clamping pieces 12 face away from each other, so that the leather can pass freely in the clamping box 9. When the embossing plate 4 is pressed down, the clamping shaft 11 is driven to rotate so that the clamping pieces 12 rotate relative to each other and in opposite circumferential directions. When contacting the leather, the leather is clamped and pulled toward the side wall of the processing box 1. A certain sliding movement is generated between the clamping pieces 12 and the leather to effectively avoid excessive stretching of the leather. When pulling, the embossing plate 4 presses the leather on the receiving plate 15 to perform embossing, thereby achieving wrinkle-free embossing. The adjusting bolt 18 is rotated to adjust the distance between the clamping piece 12 and the clamping shaft 11 to adapt to the embossing of leather of different thicknesses.

[0039] As an optional embodiment, the opposite ends of the two double-sided racks 14 are fixed with sliding rods 21 along the length direction of the double-sided racks 14, and the side of the sliding rod 21 is slidably sleeved with a sliding guide cylinder 22, and the side of the sliding guide cylinder 22 is fixed on the outer wall of the clamping box.

[0040] Specifically, two guide rods 23 are respectively arranged on both sides above the receiving plate 15, and the guide rods 23 are parallel to the conveying roller 8. An ironing plate 24 is movably arranged between the two guide rods 23. A plurality of guide slides 25 are fixed on two opposite side walls of the ironing plate 24, and the guide slides 25 are respectively slidably sleeved on the side parts of the guide rods 23 on the same side. One end of the guide rod 23 on the same side as the double-sided rack 14 extends along the length direction to form a buffer section for accommodating the ironing plate 24. The ends of the two guide rods 23 located at the buffer section are fixed with the same vertical support plate 26. The support plate 26 is fixed to the ends of the two guide rods 23 located at the buffer section. The bottom end of the plate 26 is fixed to the bottom end of the processing box 1, and each guide rod 23 is sleeved with a push spring 27, one end of the push spring 27 is fixed to the support plate 26, and the other end is fixed to the guide slide 25 close to the guide plate. A through hole 28 is opened in the center of the support plate 26, and two third transfer pulleys 29 with two edges connected to the through hole 28 are arranged outside the through hole 28. Two fourth transfer pulleys 30 are respectively arranged at the ends of both ends of the support plate 26. Two range-extending mechanisms are respectively arranged at the bottom ends of the processing box 1 on both sides of the two guide rods 23, and the range-extending mechanism includes:

[0041] The bottom end of the central shaft 31 is fixed to the bottom end of the processing box 1;

[0042] A first range-extending reel 32, which is rotatably sleeved on the central shaft 31, and a first range-extending traction rope 33 is wound around the first range-extending reel 32, and an end of the first range-extending traction rope 33 is connected to an adjacent end of the sliding rod 21 on the same side;

[0043] The second range-extending reel 34 is rotatably sleeved on the central shaft 31. The second range-extending reel 34 is fixedly connected to the first range-extending reel 32 on the same side through a linkage rod 35. A second range-extending traction rope 36 is wound around the second range-extending reel 34. The ends of the second range-extending traction rope 36 are sequentially wound around the fourth transfer pulley 30 and the third transfer pulley 29 and pass through the through hole 28 to be connected to the side of the ironing board 24.

[0044] The first range-extending reel 32 and the second range-extending reel 34 cooperate with each other to adjust the ratio of the descending distance of the embossed plate 4 and the sliding distance between the linked ironing plate 24, so that when the embossed plate 4 descends, the ironing plate 24 can quickly slide to the buffer section on the guide rod 23 close to the support plate 26.

[0045] Furthermore, the side portion of the guide rod 23 located on the upper side of the receiving plate 15 is curved toward the ironing plate 24 , and the curved end is parallel to the receiving plate 15 .

[0046] Before the embossing plate 4 is pressed down, the ironing plate 24 is pushed by the push spring 27 to be located at the upper end of the receiving plate 15 to iron the leather surface to be embossed. The sliding rod 21 slides to pull the first extended-range traction rope 33, so that the first extended-range reel 32 rotates. The rotation of the first extended-range reel 32 drives the second extended-range reel 34 to rotate through the linkage rod 35. The second extended-range reel 34 tightens the second extended-range traction rope 36, pulling the ironing plate 24 to slide to the buffer section of the guide rod 23 close to the support plate 26 to clear the area above the receiving plate 15, so that the embossing plate 4 can smoothly emboss the leather directly below. The sliding of the ironing plate 24 and the pulling of the pressing plate can effectively eliminate wrinkles on the leather.

[0047] After the embossing is completed, the embossing plate 4 rises and returns to its original position, and under the push of the push spring 27, the ironing plate 24 is driven to move back to the upper side of the receiving plate 15 to iron the leather. The guide rod 23 of the ironing plate 24 moves downward at the turning end to contact the surface of the leather to apply downward pressure to press and iron. At the same time, the second extended-range traction rope 36 is pulled to make the first extended-range reel 32 rotate in the opposite direction, and at the same time, the two sliding rods 21 are driven to move relative to each other, driving the clamping plate 12 to rotate in the opposite direction so that the clamping plate 12 releases the clamping of the leather.

In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the embodiments and still achieve the desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or continuous order shown to achieve the desired results.
