Description

Technical Field

[0001] This invention relates to the field of automotive interior manufacturing technology, specifically a punching device for automotive carpet materials. Background Technology

[0002] With the rapid development of the automotive industry, vehicle noise has become an increasingly important concern. Wheel arch sound insulation pads, as a key component in reducing vehicle noise, directly impact ride comfort and quietness. Currently, many car interiors use wheel arch sound insulation pads as carpet, which significantly reduces noise pollution during driving.

[0003] Existing automotive carpet materials require punching and shaping during production to facilitate installation inside the car. However, current punching and cutting equipment involves manually placing the carpet material before cutting it. After cutting, the cut material must be manually collected, and scraps must be manually cleaned before cutting the next carpet, resulting in low production efficiency. Furthermore, existing punching and cutting equipment requires manual positioning of the material to prevent wrinkles during the cutting process, but this manual positioning is not only costly but also inefficient.

[0004] Based on this, a punching device for automotive carpet materials is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-8 As shown, a punching device for automotive carpet material includes a base plate 1, a punching table 3 fixedly connected to the upper surface of the base plate 1 by a bracket, and a punching component 5 disposed on the upper surface of the punching table 3.

[0031] The punching assembly 5 includes a first lifting plate 51, through which a fixed post 52 is fixedly connected. A punching blade 501 is fixedly connected to the lower surface of the fixed post 52. A second fixed plate 53 is fixedly connected to the fixed post 52. A lifting plate 54 is connected to the lower surface of the second fixed plate 53 via a telescopic rod 55. The lifting plate 54 has four circumferentially distributed flat block holes. Flat blocks 502 are slidably connected to the inner sidewalls of the flat block holes. A slider groove is formed on the inner sidewall of the flat block holes. A slider 503 is fixedly connected to the sidewall of the flat block 502. The slider 503 is slidably connected to the inner sidewall of the slider groove. Several springs are fixedly connected between the second fixed plate 53 and the lifting plate 54. An anti-slip pad is provided on the lower surface of the flat block 502.

[0032] The first lifting plate 51 descends, causing the fixed column 52 to descend. The fixed column 52 then causes the second fixed plate 53, the lifting plate 54, and the punching blade 501 to descend. The lifting plate 54 causes the flattening block 502 to descend. When the flattening block 502 contacts the carpet, it works with the upward-sloping slider groove through the slider 503. If the carpet material is wrinkled, during the descent of the lifting plate 54, the anti-slip pad at the bottom of the flattening block 502 uses friction to push the carpet material outward and flatten it, thus achieving automatic flattening of the carpet material. This avoids the carpet being uneven during the punching process, which could cause deviations in the shape of the punched carpet material.

[0033] In one embodiment, such as Figure 7 and Figure 8As shown, eight opposing limiting plates 59 are fixedly connected to the upper surface of the lifting plate 54. A spring plate 56 is fixedly connected between two opposing limiting plates 59. A sliding box 57 is slidably connected between two opposing limiting plates 59. A sliding groove 58 is provided on the side wall of the limiting plate 59. A protrusion is provided on the side wall of the sliding box 57. The protrusion of the sliding box 57 is slidably connected to the inner side wall of the sliding groove 58. The flat block 502 is slidably connected to the sliding box 57 through it. A spring is fixedly connected between the sliding box 57 and the spring plate 56.

[0034] The spring and the flattening block 502 are reset.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, four fixed plates 2 are fixedly connected to the upper surface of the base plate 1 in pairs. Two rotating rollers 20 are arranged between two opposing fixed plates 2. The side wall of the fixed plate 2 is fixedly connected to a first motor 21 through a bracket. The output end of the first motor 21 is connected to the rotating roller 20.

[0036] The first motor 21 drives the carpet material to automatically roll up via the rotating roller 20, and the waste material after punching can be automatically rolled up and centrally processed, saving the time of waste collection and improving punching efficiency.

[0037] In one embodiment, such as Figure 3 and Figure 6 As shown, a material unloading assembly 6 is provided below the punching table 3. The material unloading assembly 6 includes a second lifting plate 61. A lower template 62 is rotatably mounted on the side wall of the second lifting plate 61 via a pin. A gear 66 is mounted on the pin between the lower template 62 and the second lifting plate 61. The punching table 3 has a punching hole 68. Two symmetrical rack frames 63 are fixedly connected to the inner side wall of the punching hole 68 via a bracket. A rack 67 is mounted on the inner side wall of the rack frame 63. The rack 67 meshes with the gear 66. The lower template 62 is slidably connected to the inner side wall of the punching hole 68. A receiving box 31 is placed below the punching table 3. The second lifting plate 61 has holes corresponding to the rack frames 63 and the fixing block 64.

[0038] As the punching assembly 5 descends, the unloading assembly 6 rises. The bidirectional screw 44 drives the second lifting plate 61 to rise, which in turn drives the lower template 62 to rise. The lower template 62 rotates under the cooperation of the gear 66 and the rack frame 63. When the gear 66 is no longer meshing with the rack 67, it is in a horizontal position and enters the punching hole 68. At this time, the gear 66 slides against the inner wall of the punching hole 68, and the punching hole 68 limits the gear 66 to prevent it from rotating during the punching process. As the lower template 62 rises... When the material reaches its highest point, the cutting blade 501 descends to its lowest point. The lower template 62 and the cutting blade 501 work together to cut the carpet material. The controller starts the second motor 41 in reverse, causing the lower template 62 and the cutting blade 501 to move away from each other. At this time, the lower template 62 descends, and the gear 66 and the rack 67 work together again to rotate the lower template 62 to ninety degrees. The cut material falls into the receiving box 31, completing the automatic collection of carpet material. There is no need for manual picking up of the cut carpet material, saving labor costs and improving the cutting efficiency of carpet.

[0039] In one embodiment, such as Figure 3 and Figure 4 As shown, a fixing block 64 is fixedly connected to the upper surface of the base plate 1, and a discharge block 65 is fixedly connected to the side wall of the fixing block 64. The lower template 62 has a discharge hole, and the discharge block 65 passes through the discharge hole.

[0040] During the rotation of the lower template 62, the unloading block 65 passes through the hole of the lower template 62 and pushes out the punched carpet material, making it easy to discharge.

[0041] In one embodiment, such as Figure 4 and Figure 6 As shown, a drive assembly 4 is provided above the punching table 3. The drive assembly 4 includes a worm gear 42. The worm gear 42 is rotatably mounted on the upper surface of the punching table 3. A second motor 41 is fixedly connected to the side wall of the punching table 3 via a bracket. The output end of the second motor 41 is connected to the worm gear 42. A bidirectional screw 44 is connected to the punching table 3 via a bearing. A worm wheel 43 is fixedly connected to the bidirectional screw 44. The worm wheel 43 meshes with the worm gear 42. A first limiting rod 45 is fixedly connected to the upper surface of the punching table 3. The first limiting rod 45 and the bidirectional screw 44 are both connected to a first fixed plate 46 via bearings. A first lifting plate 51 is threadedly connected to the bidirectional screw 44. The first lifting plate 51 and the first limiting rod 45 are slidably connected through the first limiting rod 45. A second limiting rod 47 is fixedly connected between the bottom plate 1 and the punching table 3. The second limiting rod 47 and the second lifting plate 61 are slidably connected through the second lifting plate 61. The second lifting plate 61 is threadedly connected to the bidirectional screw 44.

[0042] The second motor 41 drives the worm gear 42 to rotate, the worm gear 42 drives the worm wheel 43 to rotate, the worm wheel 43 drives the double-headed screw 44 to rotate, the double-headed screw 44 drives the first lifting plate 51 to descend, and the double-headed screw 44 drives the second lifting plate 61 to rise. The first limit rod 45 makes the lifting of the first lifting plate 51 more stable, and the second limit rod 47 makes the lifting of the second lifting plate 61 more stable.

[0043] In one embodiment, such as Figure 1 and Figure 2 As shown, both the second motor 41 and the first motor 21 are electrically connected to an external controller.

[0044] The controller starts the first motor 21 to transport the carpet material, and when the controller starts the second motor 41, the first motor 21 is turned off.

[0045] The above embodiment discloses a punching device for automotive carpet material. First, one end of the carpet material is wound around a rotating roller 20, and then the other end of the carpet material is fixed on another rotating roller 20. The first motor 21 is started by the controller to transport the carpet material.

[0046] When the controller starts the second motor 41, it shuts down the first motor 21. At this time, the second motor 41 drives the worm gear 42 to rotate, the worm gear 42 drives the worm wheel 43 to rotate, the worm wheel 43 drives the double screw 44 to rotate, the double screw 44 drives the first lifting plate 51 to descend, the first lifting plate 51 descends and drives the fixed column 52 to descend, the fixed column 52 drives the second fixed plate 53, the lifting plate 54, and the punching blade 501 to descend, the lifting plate 54 drives the flattening block 502 to descend. When the flattening block 502 contacts the carpet, it cooperates with the upward-sloping slider groove through the slider 503. If the carpet material is in a wrinkled state, during the descent of the lifting plate 54, the anti-slip pad at the bottom of the flattening block 502 uses friction to push the carpet material from the inside out to flatten it, similar to smoothing the carpet material by hand from the inside out. This avoids uneven carpet during the punching process, which would cause the shape of the punched carpet material to deviate.

[0047] When the flattening block 502 has flattened the carpet material, the flattening block 502 and the lifting plate 54 remain stationary, and the second fixed plate 53 continues to drive the punching cutter 501 to descend. The punching cutter 501 and the lower template 62 work together to cut the carpet material.

[0048] The spring between the spring plate 56 and the sliding box 57 drives the flat block 502 to reset. The spring force between the spring plate 56 and the sliding box 57 is less than the spring force between the second fixed plate 53 and the lifting plate 54.

[0049] As the punching assembly 5 descends, the unloading assembly 6 rises. The bidirectional screw 44 drives the second lifting plate 61 to rise, and the second lifting plate 61 drives the lower template 62 to rise. The lower template 62 rotates under the cooperation of the gear 66 and the rack frame 63. When the gear 66 is no longer meshing with the rack 67, it is in a horizontal state and enters the punching hole 68. At this time, the gear 66 slides against the inner wall of the punching hole 68. The punching hole 68 limits the gear 66 to prevent it from rotating during the punching process. When the lower template 62 rises to the highest point, the punching blade 501 descends to the lowest point. The lower template 62 and the punching blade 501 cooperate to punch the carpet material.

[0050] The controller reverses and starts the second motor 41, which drives the lower template 62 and the punching blade 501 to move away from each other. At this time, the lower template 62 descends, and the gear 66 and the rack 67 engage again, driving the lower template 62 to rotate to ninety degrees. During the rotation, the unloading block 65 passes through the hole of the lower template 62 and pushes out the punched carpet material, which falls into the receiving box 31, completing the automatic collection of carpet. There is no need for manual picking up of the manually punched carpet material, saving labor costs and improving the punching efficiency of carpet.

[0051] After the controller shuts down the second motor 41, it restarts the first motor 21 to convey the carpet material. The uncut part of the material is placed under the punching component 5 for punching again. This process is repeated automatically and intermittently to complete the carpet punching and material collection process, saving labor costs and improving punching efficiency.

[0052] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
