Description

Technical Field

[0001] This utility model relates to the field of leather production technology, and in particular to an improved automotive leather production inspection machine. Background Technology

[0002] Automotive leather refers to the use of genuine leather or artificial leather (including PVC synthetic leather, PU synthetic leather, TPO synthetic leather, or imitation suede, etc.) to cover various interior parts of a vehicle. Automotive leather can enhance the aesthetics of the car interior and the comfort of passengers. During the production process, automotive leather needs to be tested for its abrasion resistance, elasticity, and other properties to ensure the quality of the finished product.

[0003] Existing technologies, such as Chinese Patent Publication No. CN209117509U, disclose a raw leather inspection machine for automobile seat production. This machine includes a base plate, the upper surface of which is attached to the lower surface of the raw leather. The upper surface of the raw leather is attached to the lower surfaces of two anti-slip pads. The upper surfaces of the anti-slip pads are fixedly connected to the lower surface of a connecting block. A movable component is engaged with the upper surface of the connecting block. The top end of the movable component is fixedly connected to the bottom end of a sliding rod, and the top end of the sliding rod is fixedly connected to the bottom end of a connecting rod. When the abrasion resistance of the raw leather needs to be checked, a grinding wheel can polish the surface of the raw leather. A timer is used to set a specific time, allowing the user to observe whether there is obvious damage or peeling on the surface of the raw leather, thus completing the abrasion resistance test. The inspection process and manual operation are simple, saving working time and improving work efficiency. However, this invention can only test the abrasion resistance of leather. If the elasticity of the leather needs to be tested, other equipment is required.

[0004] To address the issue that automotive leather production inspection machines cannot simultaneously test abrasion resistance and elasticity, leather testing requires determining whether various indicators are qualified, such as abrasion resistance or elasticity. However, most existing testing devices are separate, with different devices serving different purposes. This often necessitates the use of multiple testing devices, which is time-consuming, labor-intensive, and takes up unnecessary space. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing automotive leather production inspection machines are not convenient for simultaneously testing abrasion resistance and elasticity properties, and to propose an improved automotive leather production inspection machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an improved automotive leather production inspection machine, comprising a base, an inspection table, and an inspection mechanism. The inspection table is fixedly connected to the surface of the base. The inspection mechanism is disposed on the surface of the inspection table and includes a grinding component, a stretching component, and a clamping component. The grinding component includes a motor, which is fixedly mounted on the surface of the inspection table. A rotating shaft is fixedly connected to the output end of the motor. The rotating shaft is rotatably connected to the inner wall of the inspection table. A grinding roller is fixedly connected to the surface of the rotating shaft. The stretching component includes a half gear, which is fixedly connected to the surface of the rotating shaft. A gear plate is meshed with the surface of the half gear and rotatably connected to the inner wall of the inspection table. A cylinder is fixedly connected to the surface of the gear plate. A connecting rod is rotatably connected to the surface of the cylinder. A clamping platform is rotatably connected to the end of the connecting rod away from the cylinder. A limiting groove is formed on the surface of the inspection table. The clamping platform is slidably connected to the surface of the limiting groove. A spring is fixedly connected to the surface of the clamping platform. The end of the spring away from the clamping platform is fixedly connected to the surface of the limiting groove.

[0007] Furthermore, the surface of the clamping stage is provided with rolling balls, which are slidably connected to the surface of the detection stage, and there are multiple rolling balls.

[0008] Furthermore, the number of cylinders, connecting rods, clamping platforms, limiting grooves, and springs are all in two sets, and the two sets of clamping platforms are arranged symmetrically.

[0009] Furthermore, the clamping assembly includes a slide groove formed on the surface of the clamping table, a slider slidably connected to the surface of the slide groove, and a clamping roller fixedly connected to the surface of the slider.

[0010] Furthermore, a pull rod is slidably connected to the inner wall of the slider, and a second spring is fixedly connected to the surface of the pull rod. The end of the second spring away from the pull rod is fixedly connected to the inner wall of the slider.

[0011] Furthermore, the surface of the clamping platform is provided with an adjustment groove, the pull rod is slidably connected to the surface of the adjustment groove, the surface of the adjustment groove is provided with a slot, the surface of the pull rod is fixedly connected with a chuck, the chuck is engaged with the surface of the slot, and there are multiple slots that are evenly distributed.

[0012] Furthermore, a rubber ring is fixedly connected to the surface of the clamping roller, and there are two sets of clamping rollers, with two clamping rollers in each set.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a detection mechanism, the leather is placed on two sets of clamping platforms. Pulling the pull rod tightens the second spring and simultaneously causes the chuck to disengage from the slot. Then, the pull rod slides along the adjustment groove, causing the slider to slide along the groove to the appropriate position. Then, the pull rod is released, and under the rebound action of the second spring, the pull rod returns to its original position. The chuck then re-enters the corresponding slot, thus using two clamping rollers to clamp the leather from above and below. This method can clamp leather of different thicknesses. After clamping, the motor is started, causing the rotating shaft to drive the polishing roller to rotate and polish the leather to test its abrasion resistance. At the same time, the rotating shaft drives the half gear to rotate. When the half gear contacts the toothed disc, it drives the toothed disc and the cylinder to rotate. The connecting rod drives the clamping platform to slide along the limiting groove and press the first spring. When the half gear disengages from the toothed disc, the clamping platform returns to its original position under the rebound action of the first spring. The reciprocating motion of the clamping platform continuously stretches the leather to test its elasticity.

[0014] 2. In this utility model, by setting up a testing mechanism, the abrasion resistance and elasticity properties of leather can be tested simultaneously without the need to use different equipment for separate testing. Furthermore, leathers of different thicknesses can be clamped and fixed for testing, which effectively improves the convenience of the equipment. Attached Figure Description

[0018] The following section will explain the specific setup and function of its testing institution 3.

[0019] In this embodiment: the testing mechanism 3 includes a grinding assembly 31, a stretching assembly 32, and a clamping assembly 33.

When the half gear 321 disengages from the toothed disc 322, the clamping table 325 returns to its original position under the rebound action of the spring 327. The reciprocating motion of the clamping table 325 continuously stretches the leather and tests its elasticity.

[0021] Specifically, the surface of the clamping stage 325 is provided with rolling balls 328, which are slidably connected to the surface of the detection stage 2, and there are multiple balls 328.

[0022] The effect achieved by the above components is that the ball bearing 328 is set to make the movement of the clamping table 325 smoother and avoid jamming.

[0023] Specifically, there are two sets of cylinder 323, connecting rod 324, clamping platform 325, limiting groove 326 and spring 327, and the two sets of clamping platforms 325 are arranged symmetrically.

[0024] The effect achieved by the above components is that the two sets of clamping platforms 325 are set to facilitate stable clamping of the leather from both ends, and at the same time facilitate stretch testing of the leather from both sides.

[0025] Specifically, the clamping assembly 33 includes a slide groove 331, which is formed on the surface of the clamping table 325. A slider 332 is slidably connected to the surface of the slide groove 331, and a clamping roller 333 is fixedly connected to the surface of the slider 332.

[0026] The effects achieved by the above components are as follows: the groove 331 and the slider 332 are provided to facilitate the adjustment of the position of the clamping roller 333, and the clamping roller 333 is provided to facilitate the clamping of leather.

[0028] The effects achieved by the above components are as follows: the pull rod 334 is set to cooperate with the chuck 338 to facilitate fixing the slider 332, and at the same time facilitate moving the slider 332; the spring 335 is set to both lock the chuck 338 into the slot 337 and utilize its rebound effect to facilitate the reset of the pull rod 334.

[0029] Specifically, the surface of the clamping table 325 is provided with an adjustment groove 336, the pull rod 334 is slidably connected to the surface of the adjustment groove 336, the surface of the adjustment groove 336 is provided with a slot 337, the surface of the pull rod 334 is fixedly connected with a chuck 338, the chuck 338 is engaged with the surface of the slot 337, and there are multiple slots 337 that are evenly distributed.

[0030] The effects achieved by the above components are as follows: the adjustment groove 336 is provided to facilitate the sliding of the pull rod 334, thereby adjusting the position of the slider 332 and the clamping roller 333; the slot 337 and the chuck 338 are provided to facilitate fixing the position of the slider 332 and the clamping roller 333; and multiple slots 337 are provided to facilitate fixing the slider 332 and the clamping roller 333 in multiple positions.

[0031] Specifically, a rubber ring 339 is fixedly connected to the surface of the clamping roller 333, and there are two sets of clamping rollers 333, with two clamping rollers 333 in each set.

[0032] The effects achieved by the above components are as follows: the rubber ring 339 is set to increase friction so that the clamping roller 333 can stably clamp the leather and avoid slippage. Each set of clamping rollers 333 is set to two so that the leather can be clamped from the top and bottom sides.

[0033] Working principle: By setting up the detection mechanism 3, the leather is placed on two sets of clamping platforms 325. Pulling the pull rod 334 tightens the second spring 335, causing the chuck 338 to disengage from the slot 337. Then, the pull rod 334 slides along the adjustment groove 336, causing the slider 332 to slide along the slide groove 331 to the appropriate position. Then, the pull rod 334 is released, and under the rebound action of the second spring 335, the pull rod 334 returns to its original position, and the chuck 338 is once again inserted into the corresponding slot 337. The leather can then be clamped from above and below by the two clamping rollers 333, and leather of different thicknesses can be clamped. After clamping is completed, the start-up mechanism is activated. The motor 311 drives the rotating shaft 312 to rotate the polishing roller 313 to polish the leather and test its abrasion resistance. At the same time, the rotating shaft 312 drives the half gear 321 to rotate. When the half gear 321 contacts the toothed disc 322, it drives the toothed disc 322 and the cylinder 323 to rotate. The connecting rod 324 drives the clamping table 325 to slide along the limiting groove 326 and press the spring 327. When the half gear 321 disengages from the toothed disc 322, the clamping table 325 returns to its original position under the rebound action of the spring 327. The reciprocating motion of the clamping table 325 continuously stretches the leather to test its elasticity.

[0034] By setting up the testing mechanism 3, the abrasion resistance and elasticity of leather can be tested simultaneously without the need to use different equipment for separate testing. Furthermore, leather of different thicknesses can be clamped and fixed for testing, which effectively improves the convenience of the equipment.
