Description

Technical Field

[0001] This utility model relates to the field of knitted fabric finishing technology, and in particular to a trimming machine for finishing knitted fabrics. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarn into loops and interlocking them using knitting needles. It is divided into warp-knitted fabric and weft-knitted fabric. Knitted fabric has the characteristics of being soft, moisture-wicking, breathable, and warm. Most of it has excellent elasticity and extensibility. Compared with woven fabric, it has the characteristics of high output and is suitable for small-batch production. After the knitted fabric is made, some edges are not flat, so it needs to be trimmed.

[0003] When trimming the edges of knitted fabric, it is necessary to press and fix the fabric. However, the contact area between the pressing structure and the knitted fabric is limited, making it difficult to press and fix it firmly. If it is not pressed firmly, the blade will cut into the area that does not need to be trimmed during trimming, which will damage the fabric. Furthermore, when trimming other edges of the fabric, it is necessary to first loosen the pressing structure, then adjust the position of the fabric, and then press it back on. This results in a slow trimming speed and poor trimming effect. Therefore, a trimming machine for knitted fabric is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an edge trimming machine for finishing knitted fabrics, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An edge trimming machine for finishing knitted fabrics includes a base plate. A rotary motor is fixedly installed on the bottom side of the base plate. The output end of the rotary motor rotatably passes through the base plate and is fixedly installed with a rotating rod. The other end of the rotating rod is fixedly connected to a placement box. The placement box is square in shape and has through holes on all four sides. A connecting frame is fixedly installed on the top side of the base plate. A second cylinder is fixedly installed on the top side of the connecting frame. The output end of the second cylinder passes through the connecting frame and is fixedly connected to a square plate. Two telescopic rods are fixedly installed on the top side of the square plate. The other ends of the two telescopic rods are fixedly connected to the bottom side of the connecting frame. A round shaft is fixedly installed on the bottom side of the square plate. A pressure plate is rotatably connected to the other side of the round shaft. The pressure plate is adapted to the placement box. A long groove is opened on the top side of the base plate, and a moving component is arranged in the long groove. An ironing component is arranged on the top side of the base plate.

[0007] Preferably, the moving component includes a guide rod fixedly installed in the long slot, a slider slidably installed on the outer side of the guide rod, a mounting plate fixedly installed on the top side of the slider, and a pull rod fixedly installed on one side of the mounting plate.

[0008] Preferably, a drive motor is fixedly installed on one side of the mounting plate, the output end of the drive motor rotates through the mounting plate and is fixedly installed with a drive shaft, and the output end of the drive shaft is fixedly connected with a blade, which is in contact with all four sides of the placement box.

[0009] Preferably, the ironing assembly includes a bracket fixedly installed on the top side of the base plate, a first cylinder fixedly installed on the top side of the bracket, the output end of the first cylinder passing through the bracket and fixedly connected to a connecting plate, and a heating plate fixedly installed on the bottom side of the connecting plate.

[0010] Preferably, a placement plate is fixedly installed on the top side of the base plate, with the heating plate facing the placement plate.

[0011] Preferably, a protective pad is fixedly installed on the bottom side of the pressure plate, and the protective pad is compatible with the placement box.

[0012] Preferably, the bottom side of the base plate is fixedly equipped with four support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the trimming machine for knitted fabric trimming has through holes on all four sides of the placement box. When placing the fabric, multiple sides that need to be trimmed only need to be extended out of the four through holes to cut multiple edges. The operation of the second cylinder can drive the pressure plate to move towards the placement box. With the protective pad fixedly installed on the bottom side of the pressure plate, the fabric can be pressed tightly so that the fabric will not move.

[0014] Pulling the lever moves the slider on the guide rod, which, together with the blade, can cut the edge of the fabric extending from the through hole. Because the blade is in contact with all four sides of the placement box, the fabric that needs to be cut can be cut off completely. Through the set round shaft, when the placement box fixedly connected to the output end of the rotating rod is rotated by the rotating motor, the pressure plate that presses the fabric will still be in a state of tightly pressing the fabric.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-4A trimming machine for finishing knitted fabrics includes a base plate 1. A rotary motor 16 is fixedly mounted on the bottom side of the base plate 1. The output end of the rotary motor 16 rotates through the base plate 1 and is fixedly mounted with a rotating rod 17. The other end of the rotating rod 17 is fixedly connected to a placement box 18. The placement box 18 is square in shape and has through holes 19 on all four sides. A connecting frame 20 is fixedly mounted on the top side of the base plate 1. A second cylinder 21 is fixedly mounted on the top side of the connecting frame 20. The output end of the second cylinder 21 passes through the connecting frame 20 and is fixed. A square plate 22 is connected, and two telescopic rods 26 are fixedly installed on the top side of the square plate 22. The other ends of the two telescopic rods 26 are fixedly connected to the bottom side of the connecting frame 20. A round shaft 23 is fixedly installed on the bottom side of the square plate 22, and a pressure plate 24 is rotatably connected to the other side of the round shaft 23. The pressure plate 24 is adapted to the placement box 18. A long groove 8 is opened on the top side of the base plate 1, and a moving component is set in the long groove 8. An ironing component is set on the top side of the base plate 1. By placing the fabric in the placement box 18, the parts of the fabric that need to be trimmed are then removed from the placement box. Through holes 19 are opened on all four sides of the placement box 18, extending outwards. The fabric requiring trimming is then positioned entirely outside the placement box 18. The second cylinder 21 is then activated, causing the square plate 22 to move downwards. This moves the pressure plate 24 and protective pad 25 below the square plate 22 towards the placement box 18. Once the pressure plate 24 and protective pad 25 are inside the placement box 18, the fabric is secured. When trimming other edges of the fabric is required, the rotary motor 16 is activated to drive the rotating rod. The placement box 18, which is fixedly connected to the output end of 17, rotates. Then the placement box 18 can rotate. When the placement box 18 rotates, the pressure plate 24 is still tightly pressing the fabric. Because the pressure plate 24 and the square plate 22 are set on the same round shaft 23 on the side close to each other, the round shaft 23 will also rotate when the placement box 18 rotates. Then the rotation is achieved during the pressing. The two telescopic rods 26 can prevent the output end of the second cylinder 21 from rotating when the pressure plate 24 rotates.

[0022] Specifically, the moving component includes a guide rod 9 fixedly installed in the long slot 8, a slider 10 slidably installed on the outside of the guide rod 9, a mounting plate 11 fixedly installed on the top side of the slider 10, a pull rod 15 fixedly installed on one side of the mounting plate 11, a drive motor 12 fixedly installed on one side of the mounting plate 11, the output end of the drive motor 12 rotates through the mounting plate 11 and is fixedly installed with a drive shaft 13, the output end of the drive shaft 13 is fixedly connected to a blade 14, the blade 14 is in contact with all four sides of the placement box 18, by starting the drive motor 12 to drive the blade 14 fixedly connected to the output end of the drive shaft 13 to rotate, when the blade 14 rotates, by pulling the pull rod 15 fixedly installed on one side of the mounting plate 11 to move, then the slider 10 can be driven to slide on the guide rod 9, then the blade 14 can cut the edge of the fabric extending from the through hole 19, because the blade 14 is in contact with all four sides of the placement box 18, so the fabric that needs to be cut can be cut completely.

[0023] Specifically, the ironing assembly includes a bracket 3 fixedly installed on the top side of the base plate 1. A first cylinder 4 is fixedly installed on the top side of the bracket 3. The output end of the first cylinder 4 passes through the bracket 3 and is fixedly connected to a connecting plate 5. A heating plate 6 is fixedly installed on the bottom side of the connecting plate 5. A placement plate 7 is fixedly installed on the top side of the base plate 1. The heating plate 6 faces the placement plate 7. By placing the fabric on the placement plate 7, and then activating the first cylinder 4, the connecting plate 5 fixedly connected to the output end moves downward and is pressed towards the trimmed edge of the fabric. Because the heating plate 6 is fixedly installed on the bottom side of the connecting plate 5, the heating plate 6 can iron the trimmed edge.

[0024] Specifically, a protective pad 25 is fixedly installed on the bottom side of the pressure plate 24. The protective pad 25 is compatible with the placement box 18. Because the protective pad 25 is made of rubber, it can fit tightly with the fabric and prevent the fabric from shifting.

[0025] Specifically, four support legs 2 are fixedly installed on the bottom side of the base plate 1.

[0026] In use: When it is necessary to trim the fabric, place the fabric in the placement box 18, and then extend the area of ​​the fabric to be trimmed out through the through holes 19 on all four sides of the placement box 18. The fabric to be trimmed will then be entirely outside the placement box 18. Then, by activating the second cylinder 21, the second cylinder 21 moves the square plate 22 downwards, which in turn moves the pressure plate 24 and protective pad 25 below the square plate 22 toward the placement box 18. Once the pressure plate 24 and protective pad 25 are inside the placement box 18, the trimming of the fabric is complete. The protective pad 25 is made of rubber, which allows it to fit tightly against the fabric, preventing displacement. After pressing the fabric, the drive motor 12 is activated to rotate the blade 14, which is fixedly connected to the output end of the drive shaft 13. As the blade 14 rotates, it moves the pull rod 15, which is fixedly mounted on one side of the mounting plate 11. This causes the slider 10 to slide on the guide rod 9, allowing the blade 14 to cut the edge of the fabric extending from the through hole 19. Because the blade 14 fits against all four sides of the placement box 18, it can cut the fabric that needs to be cut. The fabric to be trimmed is cut completely. When cutting the other side is needed after one side is finished, the pull rod 15 is pulled to move the slider 10 to the other side of the long groove 8. Then, the rotary motor 16 is started to drive the placement box 18, which is fixedly connected to the output end of the rotating rod 17, to rotate. The placement box 18 can then rotate. While the placement box 18 is rotating, the pressure plate 24 is still tightly pressing the fabric. Because the pressure plate 24 and the square plate 22 are on the same circular shaft 23 located close to each other, the circular shaft 23 also rotates while the placement box 18 is rotating. Then, rotation is achieved during pressing. The two telescopic rods 26 prevent the output end of the second cylinder 21 from rotating when the pressure plate 24 rotates. After several edges are trimmed, the fabric is placed on the placement plate 7. Then, the first cylinder 4 is activated to move the connecting plate 5, which is fixedly connected to the output end, downward. Then, it is pressed towards the trimmed edge of the fabric. Because the bottom side of the connecting plate 5 is fixedly installed with a heating plate 6, the heating plate 6 can iron the trimmed cut edge. Then, the next piece of fabric can be trimmed according to the above steps.
