[0002] Car seat leather is a kind of leather used to wrap vehicle seats. The ventilation and heating function of vehicle seats is one of the current automotive technologies. When producing vehicle seats with ventilation function, it is usually necessary to process uniform holes on the leather wrapping the car seats to facilitate ventilation and breathability of the seats. At this time, a leather punching device is often required.

[0003] The small punching device used for small batch processing in the prior art often uses a support plate with a softer material. Before punching the leather, the leather is fixed on the support plate with tape, and then the two sides of the support plate are clamped in the limit grooves on the punching device. Then, the support plate and the leather are driven to move together by the conveyor roller to process holes in the leather. However, the support plate is similar to a disposable product. When the leather is punched, holes will also be left on the support plate. Therefore, it cannot be used multiple times.

[0039] See also Figure 1-Figure 15 The present invention provides a technical solution: a punching device for car seat leather, comprising a machine base 1, a conveying module 2 is installed on the top of the machine base 1, a first buffer component 3 and a second buffer component 4 are respectively installed on both sides of the conveying module 2 at the top of the machine base 1, a punching module 5 is arranged at the top of the machine base 1 near the first buffer component 3 and the second buffer component 4, the punching module 5 includes a punching seat 51 and a punching rod 52, a collecting mechanism 7 is arranged on the top of the machine base 1 near the bottom of the punching module 5, the collecting mechanism 7 is located inside the conveying module 2, and the collecting mechanism 7 is located between the first buffer component 3 and the second buffer component 4.

[0040] The conveying module 2 includes multiple chain plates 22, movable hinges 23 and fixed hinges 26. The movable hinges 23 and the fixed hinges 26 are located between two chain plates 22. The chain plates 22 are provided with card slots 24 on both sides along their length directions. The tops of the chain plates 22 are evenly provided with multiple through holes 25 along their length directions. The movable hinges 23 and the fixed hinges 26 connect the chain plates 22 together in pairs. Multiple chain plates 22 form a conveying module 2 in the form of a conveyor belt.

[0041] The collecting mechanism 7 includes a collecting box 72, and a plurality of punching rings 75 are evenly and fixedly arranged on the top of the collecting box 72. The punching rings 75 are located below the upper chain plate 22 of the conveying module 2, and the positions of the punching rings 75 correspond one-to-one to the positions of the through holes 25. A collecting cavity 76 is opened inside the collecting box 72, and the collecting cavity 76 is connected to the cavity of the punching ring 75.

[0042] Specifically, when punching holes in the seat leather (hereinafter referred to as leather) using the punching device for seat leather described in the present invention, the leather is first laid flat on the upper chain plate 22 of the conveying module 2, and the front and rear sides of the leather (the front and rear are defined according to the conveying direction of the conveying module 2) are respectively clamped in two clamping grooves 24 close to it. When the conveying module 2 is running, the front end of the leather is first driven to move to the bottom of the punching module 5, and the movement is stopped when the through hole 25 of the upper chain plate 22 is aligned with the punching ring 75. At this time, the punching module 5 is running, and the punching seat 51 presses down the leather together with the chain plate 22 under the leather. The chain plate 22 located above the collection box 72 is in When descending, the through hole 25 thereon will be sleeved on the outer wall of the punching ring 75 opposite to it, and then the bottom side of the leather will be close to the top of the punching ring 75. At this time, the punching rod 52 inside the punching seat 51 runs, and the punching rod 52 descends and penetrates the leather and the punching ring 75 until the bottom end of the punching rod 52 reaches the inside of the collecting chamber 76. Then the punching rod 52 and the punching seat 51 are reset successively, and the upper chain plate 22 will also be reset after the pressure on it is removed. The through hole 25 is separated from the punching ring 75. At this time, the leather located above the collecting box 72 has been punched to form a row of neat holes, and then the conveying module 2 continues to run, repeating the above working process until the leather is full of holes. By providing the conveying module 2 and the collecting mechanism 7, the punching process of the leather can be made simple and convenient. Compared with the general punching device, the supporting plate used for fixing, transporting and supporting the leather is saved, and the conveying module 2 is directly used to replace its function, which greatly saves the use of materials and reduces the production cost. The conveying module 2 and the collecting mechanism 7 cooperate with each other, so that the leather waste generated after the punching is completed can fall directly into the collecting chamber 76 of the collecting box 72, which is convenient for collecting and sorting, and keeping the device clean.

[0043] Furthermore, a motor 21 for providing power to the conveying module 2 is fixedly installed on one side of the top of the base 1, and two fixed hinges 26 and two movable hinges 23 are arranged between the two chain plates 22. The two fixed hinges 26 are respectively arranged at the two ends of the chain plates 22, and the two ends of the fixed hinges 26 are respectively fixedly connected to the opposite sides of the two chain plates 22, and the two movable hinges 23 are respectively arranged between the two fixed hinges 26, and the two ends of the movable hinges 23 are respectively slidably connected to the slots 24 on the opposite sides of the two chain plates 22. The main functions of the fixed hinge 26 and the movable hinge 23 are to connect the chain plates 22 in pairs to form a complete conveyor belt, but the movable hinge 23 can slide left and right between the two chain plates 22 through the slot 24 (the sliding ability of the movable hinge 23 on the slot 24 is relatively weak). The purpose of setting the slot 24 and the slidable movable hinge 23 is that when the leather is installed on the conveying module 2, the front and rear sides of the leather can be quickly inserted into the slot 24 to limit its front and rear positions, and then the movable hinge 23 is slid to make its side abut against the side of the leather, so that the two movable hinges 23 can limit the left and right positions of the leather. The general punching device fixes the leather by fixing the leather on the supporting plate with tape. In comparison, the fixing method for leather provided by the present invention is more convenient and saves materials in terms of fixing or disassembly, and can quickly align and position the leather. The working principle of the motor 21 providing power to the conveying module 2 is similar to the principle of the motor 21 driving the conveyor belt to run, so it will not be explained in detail.

[0044] Furthermore, a slide 71 is fixedly provided at one end of the bottom of the collection box 72, and the slide 71 is connected to the collection chamber 76. Slide rods 73 are fixedly provided on both sides of the collection box 72 at the top of the base 1. The slide rods 73 are slidably connected to the sides of the collection box 72, and an ejection mechanism 74 is provided in the middle of the top end of the collection box 72.

[0045] Furthermore, a support seat 53 is fixedly provided on the top of the machine base 1 at a position close to the first buffer assembly 3 and the second buffer assembly 4, a sliding mechanism 54 is provided on the top of the support seat 53 facing the side of the conveying module 2, a lifting mechanism 55 is installed on the bottom of the sliding mechanism 54, the bottom end of the lifting mechanism 55 is fixedly connected to the top of the punching seat 51, the punching rod 52 is located in the bottom of the punching seat 51, and the position of the punching rod 52 corresponds one-to-one to the position of the punching ring 75. The sliding mechanism 54 and the lifting mechanism 55 can drive the punching seat 51 to move left and right and up and down. This is the prior art and will not be elaborated. When punching leather, the punching seat 51 first descends, and then the bottom end of the punching seat 51 abuts against the upper layer of the leather, pressing the leather and the chain plate 22 under the leather down together, and then the through hole 25 is sleeved on the punching ring 75, and finally the bottom side of the chain plate 22 abuts against the top side of the collection box 72, and the top end of the punching ring 75 abuts against the bottom layer of the leather, and then the punching rod 52 descends to punch (the working principle of the punching rod 52 is the prior art and will not be elaborated).

[0046] Furthermore, one end of the collecting box 72 is fixedly connected to one end of the connecting rod 6, and the other end of the connecting rod 6 passes through the outer wall of the machine base 1 and is fixedly connected to the sliding mechanism 54. The connecting rod 6 is arranged so that the sliding mechanism 54 can drive the collecting box 72 to move back and forth on the sliding rod 73 while driving the punching seat 51 to move left and right, so that the collecting box 72 and the punching seat 51 can move synchronously, and the positions of the punching rod 52 and the punching ring 75 can always correspond. Under such operating conditions, the punching rod 52 can punch holes at different positions on the leather, and holes of different array combinations can be processed on the leather, thereby improving the overall functionality of the device, and the collecting box 72 can synchronously collect the punching waste to ensure that the waste can be collected cleanly.

[0047] Furthermore, the first buffer assembly 3 includes a first buffer plate 31 and two first pillars 33. The two first pillars 33 are fixedly connected to one end of the top of the base 1. The first buffer plate 31 is sleeved between the two first pillars 33. The two first pillars 33 are sleeved with a first spring 34, and the two ends of the first spring 34 are respectively fixedly connected to the first buffer plate 31 and the base 1. A first air cylinder 32 is fixedly installed on the top of the base 1 between the two first pillars 33. The top of the air cylinder rod of the first air cylinder 32 is fixedly connected to the bottom end of the first buffer plate 31. A first conduit 35 is arranged between the collection box 72 and the first air cylinder 32. The first conduit 35 connects the collection chamber 76 with the first air cylinder 32. When the punching seat 51 descends to perform the punching operation, the side of the punching seat 51 will first abut against the top of the first buffer plate 31, and the first buffer plate 31 and the first spring 34 cooperate to buffer the punching seat 51. At the same time, the first buffer plate 31 drives the cylinder rod of the first air cylinder 32 to be pressed down, so that the air inside the first air cylinder 32 enters the first conduit 35, and then is poured into the collecting chamber 76 through the first conduit 35. The cross-section of the collecting chamber 76 is sloped. Under the blowing of the airflow introduced through the first conduit 35, the punching waste accumulated in the collecting chamber 76 can be blown to the slide 71. In this way, the staff can leave the inside of the device and place a trash can under the ramp to collect the waste. When the punching seat 51 is reset, the first buffer plate 31 and the cylinder rod of the first cylinder 32 are reset through the action of the first spring 34. By setting the first buffer assembly 3, energy can be collected while buffering the punching seat 51, and converted into airflow thrust to remove the waste from the device, which not only ensures the cleanliness of the inside of the device, but also makes it convenient for the staff to collect the waste, so that the staff does not have to specially clean the waste inside the device, thereby improving work efficiency.

[0048] Furthermore, the second buffer assembly 4 includes a second buffer plate 41 and two second pillars 43. The two second pillars 43 are fixedly connected to the top of the base 1 at one end away from the first buffer assembly 3. The second buffer plate 41 is sleeved between the two second pillars 43. The two second pillars 43 are sleeved with a second spring 44, and the two ends of the second spring 44 are respectively fixedly connected to the second buffer plate 41 and the base 1. A second air cylinder 42 is fixedly installed on the top of the base 1 between the two second pillars 43. The top of the air cylinder rod of the second air cylinder 42 is fixedly connected to the bottom end of the second buffer plate 41, and a second conduit 45 is arranged between the collection box 72 and the second air cylinder 42.

[0049] Furthermore, the ejection mechanism 74 includes two ejector rods 741, which are slidably arranged in the middle of the top end of the collecting box 72, and the two ejector rods 741 are respectively close to the two sides of the punching ring 75, and rollers are rotatably arranged on the top of the ejector rods 741, and a return spring 742 is arranged between the bottom end of the ejector rod 741 and the inner wall of the collecting box 72, and a push rod cylinder 744 is fixedly installed inside the collecting box 72 near the bottom of the ejector rod 741, and the cylinder rod of the push rod cylinder 744 is fixedly connected to one end of the rope 743, and the other end of the rope 743 is fixedly connected to the bottom end of the ejector rod 741, and the push rod cylinder 744 is connected to the second cylinder 42 through the second conduit 45. The buffering function of the second buffer assembly 4 on the punching seat 51 is the same as that of the first buffer assembly 3, and when the punching seat 51 drives the second buffer plate 41 to descend, the second buffer plate 41 drives the cylinder rod of the second air cylinder 42 to press down, so that the air inside the second air cylinder 42 enters the push rod air cylinder 744 through the second conduit 45, and the cylinder rod of the push rod air cylinder 744 extends out and pulls the push rod 741 down through the rope 743. When the punching seat 51 is reset, the second buffer plate 41 is reset by the action of the second spring 44, and the push rod 741 is reset by the action of the reset spring 742, and the cylinder rods of the second air cylinder 42 and the push rod air cylinder 744 are also reset at the same time. When punching is not in progress, the roller on the top of the push rod 741 is close to the bottom of the upper chain plate 22. When punching is in progress, the push rod 741 descends to the inside of the collecting box 72 without hindering the descent of the chain plate 22 and the leather. When the punching is completed, the push rod 741 automatically resets to push the chain plate 22 and the leather out and resets them to prevent the chain plate 22 and the leather from being stuck on the punching ring 75 and hindering the operation of the conveying module 2.

[0050] Furthermore, the first conduit 35 and the second conduit 45 are both hoses, and the cross-sectional shape of the punching seat 51 is T-shaped. A certain length is reserved for the first conduit 35 and the second conduit 45, so as not to hinder the left-right movement of the collection box 72.

[0051] Furthermore, the top layers of the collecting box 72, the first buffer plate 31 and the second buffer plate 41 are all made of rubber material, which can reduce wear.

[0052] Working principle: When using this device to punch leather, first lay the leather flat on the upper chain plate 22 of the conveying module 2, and respectively clamp the front and rear sides of the leather (the front and rear are defined according to the conveying direction of the conveying module 2) in two clamping grooves 24 close to it to limit its front and rear positions, and then slide the movable hinge 23 to make its side edges abut against the side edges of the leather, so that the two movable hinges 23 can limit the left and right positions of the leather, and then start the conveying module 2. When the conveying module 2 is running, it first drives the front end of the leather to move to the bottom of the punching module 5, and stops moving when the through hole 25 of the upper chain plate 22 is aligned with the punching ring 75. At this time, the punching module 5 is running, and the punching seat 51 descends and punches the leather together with the leather below. The chain plates 22 are pressed down together. When the chain plate 22 located above the collecting box 72 descends, the through hole 25 thereon will be sleeved on the outer wall of the punching ring 75 opposite to it, and then the bottom side of the leather will be close to the top of the punching ring 75. At this time, the punching rod 52 inside the punching seat 51 runs, and the punching rod 52 descends and penetrates the leather and the punching ring 75 until the bottom end of the punching rod 52 reaches the inside of the collecting chamber 76. Then the punching rod 52 and the punching seat 51 are reset in succession. After the pressure on the upper chain plate 22 is removed, it will also be reset. The through hole 25 is separated from the punching ring 75. At this time, the leather located above the collecting box 72 has been punched to form a row of neat holes, and then the conveying module 2 continues to run, repeating the above working process until the leather is full of holes.

[0053] When the punching seat 51 descends to perform the punching work, the side of the punching seat 51 will first abut against the top of the first buffer plate 31 and the second buffer plate 41, and the first buffer plate 31 and the first spring 34 cooperate to buffer the punching seat 51. At the same time, the first buffer plate 31 drives the cylinder rod of the first air cylinder 32 to press down, so that the air inside the first air cylinder 32 enters the first conduit 35, and then is poured into the collecting chamber 76 through the first conduit 35. The cross-section of the collecting chamber 76 is sloped. Under the blowing of the airflow introduced through the first conduit 35, the punching waste accumulated in the collecting chamber 76 can be blown to the slide 71, thereby leaving the inside of the device. The staff can place a trash can under the ramp to collect the waste. The second buffer component 4 has the same buffering function for the punching seat 51 as the first buffer component 3, and when the punching seat 51 drives the second buffer plate When the punching seat 51 is reset, the second buffer plate 41 is reset by the action of the second spring 44, and the push rod 741 is reset by the action of the reset spring 742, and the air cylinder rods of the second air cylinder 42 and the push rod air cylinder 744 are also reset at the same time. Through this transmission mode, when punching, the push rod 741 descends to the inside of the collection box 72 without hindering the descent of the chain plate 22 and the leather. When the punching is completed, the push rod 741 automatically resets to push the chain plate 22 and the leather out and reset, so as to prevent the chain plate 22 and the leather from being stuck on the punching ring 75 and hindering the operation of the transmission module 2.
