Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, specifically a knitted fabric trimming machine that facilitates the replacement of trimming tools. Background Technology

[0002] A knitted fabric trimming machine is a specialized piece of equipment used to trim the edges of knitted fabrics as needed. It uses a cutting tool to remove excess material from the fabric edges, making the edges smooth and the dimensions meet the process requirements, thus facilitating subsequent processing of the fabric.

[0003] Traditional trimming machine blades are mostly fixed, making it difficult to quickly change to different blades. This makes it difficult to trim knitted fabrics into different shapes, and changing them is also quite troublesome, requiring the screws to be removed one by one and the blade position to be manually calibrated, which is quite time-consuming.

[0004] Therefore, this utility model provides a knitted fabric trimming machine that facilitates the replacement of trimming blades. Utility Model Content

[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a knitted fabric trimming machine that facilitates the replacement of trimming tools is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A knitted fabric trimming machine that facilitates the replacement of trimming tools, comprising a base plate, a worktable fixedly connected to the top of the base plate, a first placement groove fixedly connected to the top of the worktable, a first motor fixedly connected to the top of the first placement groove, a first lead screw rotatably connected to the output end of the first motor, a slider slidably connected to the middle of the first lead screw, a limit groove fixedly connected to the side wall of the slider, a tool body detachably connected to the middle of the limit groove, and a second spring slidably connected to the bottom of the limit groove, penetrating the tool body. The tool body has a fixing bolt fixed to the top of the second spring, which passes through the limiting groove. Two sets of symmetrically arranged placement blocks are fixed to the side wall of the first placement groove. A first spring is fixed to the middle of the placement block, and a buckle is fixed to the end of the first spring. A clamping assembly is fixed to the top of the worktable away from the first placement groove. With the above structure, the tool body can be quickly replaced by the cooperation of the fixing bolt and the second spring. The adjustable height of the tool body can avoid the limitation of trimming caused by the fixed position of the tool body, increase the diversity of trimming types, and avoid the problem of waste caused by insufficient process adaptation.

[0007] Preferably, the clamping assembly includes a fixing frame. Two symmetrically arranged fixing frames are fixedly connected to the top of the base plate away from the first placement slot. A second motor is fixedly connected to the side wall of the fixing frame. A second motor is rotatably connected to the output end of the second motor. A fourth lead screw is rotatably connected to the output end of the second motor. A slider is slidably connected to the middle of the fourth lead screw. A second placement slot is fixedly connected to the side wall of the slider. A third motor is fixedly connected to the top of the second placement slot. A second lead screw is rotatably connected to the output end of the third motor. Two symmetrically arranged elastic clamps are slidably connected to the middle of the second lead screw. With the above structure, the device can be adapted to knitted fabrics of different sizes, accommodate diverse production needs, and use the fourth lead screw to drive the clamping device to slide, which can ensure the consistency of the cutter body when trimming the fabric and avoid the problem of serrated edges of the fabric caused by mismatched movement speeds.

[0008] Preferably, a fixing block is fixedly connected to the side wall of the base plate near the fixing frame, and a first telescopic rod is fixedly connected to the top of the fixing block. Two symmetrically arranged cleaning rollers are slidably connected to the output end of the first telescopic rod, and a sliding plate is slidably connected to the top of the cleaning rollers. With the above structure, the rough edges and fabric scraps generated during the trimming process can be effectively cleaned, preventing impurities from sticking to the edge or surface of the fabric, making the edge of the fabric smooth and burr-free, and improving the flatness and aesthetics of the finished product.

[0009] Preferably, the workbench has a discharge port in the middle and is located at the center. A placement box is fixed to the bottom of the discharge port, and a collection box is slidably connected to the middle of the placement box. With the above structure, it is easy for workers to clean it, avoiding the problem of dry debris scattering everywhere and needing to be swept repeatedly, and effectively improving the safety hazard of excessive debris generating static electricity and causing explosion.

[0010] Preferably, two symmetrically arranged second telescopic rods are fixedly connected to the middle of the workbench near the first placement slot. A push plate is fixedly connected to the output end of the second telescopic rod. With the above structure, the problem of workers needing to stop the machine to clean it can be effectively reduced, and the uncollected debris can be prevented from adhering to the surface of the knitted fabric due to static electricity and other problems.

[0011] Preferably, two guide rods are fixedly connected to the middle of the fixing frame. The two guide rods are symmetrically arranged and pass through the slider. Through the above structure, the motion accuracy of the clamping assembly can be effectively improved, and the vibration generated during sliding can be reduced, which can cause the tool body to have unstable cutting when trimming it.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 4 As shown in the figure, a knitted fabric trimming machine with easy-to-change trimming cutters according to an embodiment of the present invention includes a base plate 1, a worktable 11 fixedly connected to the top of the base plate 1, a first placement groove 12 fixedly connected to the top of the worktable 11, a first motor 13 fixedly connected to the top of the first placement groove 12, a first lead screw 14 rotatably connected to the output end of the first motor 13, a slider slidably connected to the middle of the first lead screw 14, a limiting groove 17 fixedly connected to the side wall of the slider, a cutter body 16 detachably connected to the middle of the limiting groove 17, a second spring 110 slidably connected to the bottom of the limiting groove 17 and penetrating the cutter body 16, a fixing bolt 111 fixedly connected to the top of the second spring 110 and penetrating the limiting groove 17, two sets of symmetrically arranged placement blocks 15 fixedly connected to the side wall of the first placement groove 12, a first spring 19 fixedly connected to the middle of the placement block 15, a buckle 18 fixedly connected to the end of the first spring 19, and the worktable 11 is located away from the first placement groove 12. A clamping assembly is fixed to the top of the slot 12. During operation, after the fabric is fixed in place by the clamping assembly, the first motor 13 is started to adjust the height of the cutter body 16. When the cutter body 16 contacts the buckle 18, the slider will overcome the elastic force of the first spring 19 and push the buckle 18 to the middle of the placement block 15, so that it can slide upward smoothly and be limited. If the cutter is worn and needs to be replaced, the limiting block at the top of the fixing bolt 111 is hinged and will close when pulled down, making it easy to replace the cutter body 16. To fix it, the fixing bolt 111 can be pushed to the top of the limiting slot 17. Through the above structure, the fixing bolt 111 and the second spring 110 can be used to quickly replace the cutter body 16. The adjustable height structure of the cutter body 16 can avoid the limitation of trimming caused by the fixed position of the cutter body 16, increase the diversity of trimming types, and avoid the problem of waste caused by insufficient process adaptation.

[0024] like Figures 1 to 3As shown, the clamping assembly includes a fixed frame 2. Two symmetrically arranged fixed frames 2 are fixedly connected to the top of the base plate 1 away from the first placement slot 12. A second motor 21 is fixedly connected to the side wall of the fixed frame 2. The output end of the second motor 21 is rotatably connected to a fourth lead screw 26. A slider is slidably connected to the middle of the fourth lead screw 26. A second placement slot 22 is fixedly connected to the side wall of the slider. A third motor 23 is fixedly connected to the top of the second placement slot 22. A second lead screw 24 is rotatably connected to the output end of the third motor 23. Two symmetrically arranged elastic clamps 25 are slidably connected to the middle of the second lead screw 24. During operation, the third motor 25 is activated. 3. After adjusting the distance between the two elastic clamps 25 to a suitable position, the elastic clamps 25 and the slider in the middle of the second lead screw 24 are hinged. Adjust the angle of the elastic clamps 25 and fix the knitted fabric. Then start the second motor 21. The output end of the second motor 21 drives the slider and the clamping assembly to slide. At this time, the fabric contacts the cutter body 16 and trims it. Through the above structure, the device can be adapted to knitted fabrics of different sizes and is compatible with diverse production needs. Moreover, the use of the fourth lead screw 26 to drive the clamping device to slide can ensure the consistency of the cutter body 16 when trimming the fabric and avoid the problem of the fabric edge being jagged due to mismatched movement speed.

[0025] like Figure 1 As shown, a fixing block 3 is fixedly connected to the side wall of the base plate 1 near the fixing frame 2. A first telescopic rod 31 is fixedly connected to the top of the fixing block 3. Two symmetrically arranged cleaning rollers 32 are slidably connected to the output end of the first telescopic rod 31. A sliding plate 33 is slidably connected to the top of the cleaning rollers 32. During operation, after trimming the knitted fabric, the fabric can be passed through the middle of the cleaning rollers 32, and the distance between the two cleaning rollers 32 can be adjusted to make them contact the fabric for cleaning. Through the above structure, the rough edges and fabric scraps generated during the trimming process can be effectively cleaned, preventing impurities from sticking to the edge or surface of the fabric, making the edge of the fabric smooth and burr-free, and improving the flatness and aesthetics of the finished product.

[0026] like Figures 1 to 2 As shown, a discharge port 4 is provided in the middle of the workbench 11 and is located in the center. A placement box 41 is fixed to the bottom of the discharge port 4, and a collection box 42 is slidably connected to the middle of the placement box 41. During operation, the debris generated during trimming can fall into the middle of the collection box 42 due to gravity through the discharge port 4. The collection box 42 stores water in the middle, which can wet the debris. After the collection box is saturated, it can be cleaned by sliding the collection box 42. With the above structure, it is easy for workers to clean it, avoiding the problem of dry debris scattering everywhere and needing to be cleaned repeatedly. It effectively improves the safety hazard of excessive debris generating static electricity and causing explosion.

[0027] like Figure 1As shown, two symmetrically arranged second telescopic rods 5 are fixedly connected to the middle of the workbench 11 near the first placement slot 12. A push plate 51 is fixedly connected to the output end of the second telescopic rod 5. During operation, when trimming the knitted fabric, the second telescopic rod 5 is activated. The output end of the second telescopic rod 5 can drive the push plate 51 to slide back and forth on the top of the workbench 11, pushing the debris that falls on the surface to the middle of the collection box 42. Through the above structure, the problem of workers needing to stop the machine to clean it can be effectively reduced, and the debris that has not been collected can be prevented from adhering to the surface of the knitted fabric due to static electricity and other problems.

[0028] like Figure 2 As shown, two guide rods 6 are fixedly connected to the middle of the fixed frame 2. The two guide rods 6 are symmetrically arranged and pass through the slider. During operation, when the elastic clamp 25 moves the knitted fabric back and forth, the guide rods 6 can effectively limit the slider and prevent it from deviating. Through the above structure, the motion accuracy of the clamping component can be effectively improved, and the vibration generated during sliding can be reduced, which can cause the tool body 16 to have unstable cutting when trimming it.

[0029] like Figure 3 As shown, the blade body 16 is made of high-carbon tool steel, which provides high wear resistance during operation. It is also quite sharp, capable of quickly cutting fibers with its high-hardness cutting edge. This structure allows for effective trimming of knitted fabrics, and even if the cutting edge wears down, it can be quickly re-sharpened using a regular grinding wheel.

[0030] During operation, after securing the fabric using the clamping assembly, the first motor 13 is activated to adjust the height of the cutter body 16. When the cutter body 16 contacts the buckle 18, the slider overcomes the elastic force of the first spring 19, pushing the buckle 18 to the middle of the placement block 15, allowing it to slide upwards smoothly and be limited. If the cutter needs to be replaced due to wear, the limiting block at the top of the fixing bolt 111 is hinged and will close when pulled downwards, facilitating the replacement of the cutter body 16. To fix it, simply push the fixing bolt 111 to the top of the limiting groove 17. The third motor 23 is activated, and after adjusting the distance between the two elastic clamps 25 to a suitable position, the elastic clamps 25 and the slider in the middle of the second lead screw 24 are hinged. The angle of the elastic clamps 25 is adjusted to fix the knitted fabric. Then, the second motor 21 is activated, and the output end of the second motor 21 drives the slider and clamp. The component slides, at which point the fabric comes into contact with the cutter body 16 for trimming. After trimming the knitted fabric, the fabric can be passed through the middle of the cleaning roller 32, and the distance between the two cleaning rollers 32 can be adjusted to ensure close contact with the fabric for cleaning. The debris generated during trimming falls through the feed port 4 into the middle of the collection box 42 due to gravity. The collection box 42 contains water, which wets the debris. Once the collection box is saturated, it can be emptied by sliding the collection box 42. During the trimming process of the knitted fabric, the second telescopic rod 5 is activated. The output end of the second telescopic rod 5 can drive the push plate 51 to slide back and forth on the top of the worktable 11, pushing the debris falling on the surface to the middle of the collection box 42. When the elastic clamp 25 moves the knitted fabric back and forth, the guide rod 6 can effectively limit the slider to prevent deviation. This material has high wear resistance and is relatively sharp, and can quickly cut fibers with its high-hardness cutting edge.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
