Description

Technical Field

[0001] The utility model relates to the field of TPU processing equipment, in particular to a structure that is convenient for trimming and rolling. Background Art

[0002] TPU, a thermoplastic polyurethane, is increasingly popular for its superior performance and environmentally friendly design. TPU not only boasts high tension, high tensile strength, toughness, and aging resistance, but is also a proven environmentally friendly material. TPU film is a thin film made from TPU pellets through a variety of processing techniques. It is widely used in shoes, branding, airbags, and oil bags.

[0003] During TPU processing, coating is applied to the film. Conventional coating equipment cannot fully coat the film. Some water-based coatings also curl on the edges after drying or corona treatment. If the film is directly rolled up, the film will be thick on the sides and thin in the middle, making it difficult to roll neatly. This also results in excessive secondary slitting losses. Therefore, this application proposes a structure that facilitates trimming and winding for TPU processing. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a structure that is convenient for trimming and rolling.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a structure for convenient trimming and winding, comprising a frame, a winding frame is provided on one side of the top of the frame, a cutting frame is provided on the other side of the top of the frame, adjustment slots are provided on both sides of the winding frame close to the cutting frame, adjustment blocks are slidably provided in the adjustment slots, the adjustment blocks are fixedly connected to adjustment limiters, adjustment rollers are provided on the inner sides of the adjustment limiters, openings are provided on the sides of the adjustment slots away from each other, and fixing bolts are provided in the openings, and the fixing bolts are threadedly connected to the adjustment blocks;

[0006] Through the above technical solution, when the winding roller is winding, the TPU film can be well wound on the outside of the winding roller by adjusting the limit and blocking of the roller. In this way, the TPU film will not tilt when it is wound. At the same time, when the diameter of the winding roller becomes larger, the TPU film can be accurately adjusted by adjusting the height of the limiter, which is very efficient and beneficial.

[0007] Both sides of the inner top of the cutting frame are provided with slide grooves, and sliders are slidably connected in the slide grooves. The bottoms of the sliders are fixedly connected to the vertical frames, and the bottoms of the vertical frames are horizontally provided with a set of two parallel mounting feet. A blade is vertically mounted on each set of mounting feet, and a limiting wheel is provided on the adjacent side of each set of mounting feet.

[0008] Through the above technical solution, by adjusting the position gap of the vertical frame in a targeted manner, the blade can be adjusted to different distances and ends, and the TPU film passes through the blade between the vertical frames to achieve the cutting of the TPU film. At the same time, when cutting the edges, the limiting wheel reduces the cutting resistance, so that the TPU film can be flexibly cut into different sizes while being processed smoothly, ensuring its good passability and processing performance.

[0009] As a further description of the above technical solution:

[0010] A winding roller is rotatably provided inside the winding frame, one end of the winding roller passes through the winding frame and is connected to a pulley, the pulley is connected to a motor via a belt, and the motor is fixedly mounted on the outside of the winding frame;

[0011] Through the above technical solution: the motor drives the winding roller through the pulley and belt to realize the winding of the TPU film after cutting, realizing the integration of cutting and winding, and ensuring the good processing and processing quality of the TPU film.

[0012] As a further description of the above technical solution:

[0013] Limiting slots are provided in the vertical frames, and limiting blocks are slidably arranged in the limiting slots, and the adjacent sides of the limiting blocks are connected to an upper mounting foot of each group of mounting feet;

[0014] Through the above technical solution, the mounting feet can provide a buffer for the blade to ensure smooth cutting of TPU by the blade.

[0015] As a further description of the above technical solution:

[0016] Springs are fixedly connected to both sides of the top of the limit block, the tops of the springs are fixedly connected to the inner top of the limit slot, and the springs are in a compressed state;

[0017] Through the above technical solution, the spring allows the limit block to have space to move up and down, and the limit block enables the mounting foot to move up and down, so that the blade can be changed from a hard connection to a connection with a buffering effect. When the diameter of the winding roller becomes larger, the TPU film will not be damaged due to the change in the angle between the blade and the cutting angle being too large.

[0018] As a further description of the above technical solution:

[0019] A threaded rod is rotatably connected in each of the slide grooves, and each of the threaded rods is threadedly connected to the slider;

[0020] Through the above technical solution, the slider slides in the slide groove to adjust the position of the vertical frame and adjust the edge size of the cut TPU material.

[0021] As a further description of the above technical solution:

[0022] The ends of the threaded rods that are away from each other pass through the cutting frame and extend, the ends of the threaded rods that are away from each other are fixedly connected to a worm wheel, one side of the worm wheel is meshedly connected to a worm, and the worm is rotatably connected to a mounting block;

[0023] Through the above technical solution, the worm wheel rotates to rotate the threaded rod, and the threaded rod drives the slider to adjust its position.

[0024] As a further description of the above technical solution:

[0025] The mounting blocks are mounted on the top of the cutting frame, and the mounting blocks are rotatably connected to handles, which are connected to the upper part of the worm;

[0026] Through the above technical solution, the worm can drive the worm wheel to rotate through the handle.

[0027] The utility model has the following beneficial effects:

[0028] 1. In the present invention, after the TPU coating is cured, the distance between the vertical frames is adjusted according to the actual coating conditions and the curling conditions. During the adjustment, the worm is rotated by the handle, and the worm drives the slider to slide through the threaded rod through the worm gear, so that the two vertical frames can cut TPU films of different sizes according to the actual cutting distance. While the TPU film can be well cut, the limiting wheel is combined to make the cutting smooth, which is convenient for the subsequent winding operation without secondary slitting, and has good effect and high efficiency.

[0029] 2. In the present invention, the motor realizes the rotation of the winding roller through the pulley. When the winding roller rotates, the diameter becomes larger. At this time, the height of the limiter and the height distance between the limiter and the winding roller are adjusted, so that the TPU winding roller can cooperate with the winding roller to rewind the TPU anytime and anywhere, thereby achieving stable winding quality and preventing the occurrence of uneven force on the TPU due to loosening and tightening.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Reference Figure 1-4 The utility model provides an embodiment of a structure for convenient edge trimming and winding, including a frame 1, a winding frame 2 is provided on one side of the top of the frame 1, and a cutting frame 10 is provided on the other side of the top of the frame 1. Adjustment slots 8 are provided on both sides of the winding frame 2 close to the cutting frame 10, and adjustment blocks 24 are slidably provided in the adjustment slots 8. The adjustment blocks 24 are fixedly connected with adjustment limit members 4, and adjustment rollers 5 are provided on the inner sides of the adjustment limit members 4. The adjustment slots 8 are opened on the sides away from each other and fixing bolts 9 are provided in the openings. The fixing bolts 9 are threadedly connected with the adjustment blocks 24. When the winding roller 3 is wound, the TPU film can be limited and blocked by the adjustment roller 5 and well wound on the outside of the winding roller 3. In this way, the TPU film will not be tilted when it is wound. At the same time, when the diameter of the winding roller 3 becomes larger, the TPU film can be accurately adjusted in limit by adjusting the height of the adjustment limit member 4, which is very efficient and advantageous.

[0038] Slide grooves 21 are provided on both sides of the inner top of the cutting frame 10, and sliders 19 are slidably connected in the slide grooves 21. The bottom of the sliders 19 is fixedly connected to the vertical frame 12. A group of two parallel mounting feet 15 are horizontally provided at the bottom of the vertical frame 12. A blade 14 is vertically installed on each set of mounting feet 15. A limiting wheel 18 is provided on the adjacent side of each set of mounting feet 15. By targeted adjustment of the position gap of the vertical frame 12, the blade 14 can be adjusted to different distances and ends. The TPU film passes through the blade 14 between the vertical frames 12 to achieve edge cutting of the TPU film. At the same time, when cutting the edges, the limiting wheel 18 reduces the cutting resistance, so that the TPU film can be flexibly cut into different sizes while being processed smoothly, ensuring its good passability and processing performance.

[0039] A winding roller 3 is rotatably provided on the inner side of the winding frame 2. One end of the winding roller 3 passes through the winding frame 2 and is connected to a pulley 7. The pulley 7 is connected to a motor 6 through a belt. The motor 6 is fixedly mounted on the outer side of the winding frame 2. The motor 6 drives the winding roller 3 through the pulley 7 and the belt to realize the winding of the TPU film after cutting, thereby realizing the integration of cutting and winding, and ensuring the good processing and processing quality of the TPU film.

[0040] A limiting groove 23 is provided in the vertical frame 12, and a limiting block 25 is slidably set in the limiting groove 23. The side close to the limiting block 25 is connected to a mounting foot 15 above each set of mounting feet 15. The mounting foot 15 can provide a buffer for the blade 14 to ensure smooth cutting of the TPU by the blade 14.

[0041] Springs 22 are fixedly connected to both sides of the top of the limit block 25, and the top ends of the springs 22 are fixedly connected to the inner top of the limit groove 23. The springs 22 are in a compressed state. The springs 22 allow the limit block 25 to have space to move up and down. The limit block 25 enables the mounting foot 15 to move up and down, so that the blade 14 can be changed from a hard connection to a connection with a buffering effect. When the diameter of the winding roller 3 becomes larger, the TPU film will not be damaged due to the change in the angle between the winding roller 3 and the blade 14, resulting in an excessive cutting angle.

[0042] A threaded rod 20 is rotatably connected in each chute 21 , and the threaded rod 20 is threadedly connected to the slider 19 . The slider 19 slides in the chute 21 to adjust the position of the vertical frame 12 and adjust the edge size of the cut TPU material.

[0043] The ends of the threaded rods 20 that are away from each other pass through the cutting frame 10 and extend, and the ends of the threaded rods 20 that are away from each other are fixedly connected to the worm gear 16, and one side of the worm gear 16 is meshed with a worm 17, and the worm 17 is rotatably connected to the mounting block 11. The rotation of the worm gear 16 can cause the threaded rod 20 to rotate, and the threaded rod 20 drives the slider 19 to adjust its position.

[0044] The mounting block 11 is mounted on the top of the cutting frame 10 . The mounting block 11 is rotatably connected to a handle 13 . The handle 13 is connected to the upper portion of the worm 17 . The worm 17 can drive the worm wheel 16 to rotate through the handle 13 .

[0045] Working principle: When the TPU film is processed, cut and rolled up, when this device is working, after the TPU coating is cured, the distance between the vertical frames 12 is adjusted according to the actual coating situation and the curling situation. During adjustment, the worm 17 is rotated by the handle 13, and the worm 17 realizes that the threaded rod 20 drives the slider 19 to slide through the worm gear 16, so that the two vertical frames 12 can cut TPU films of different sizes according to the actual cutting distance, and the TPU film can be well cut. At the same time, the limiting wheel 18 makes it cut smoothly, which facilitates the subsequent rolling operation without secondary slitting, with good effect and high efficiency. Figure 4 The tangent of the middle winding roller 3 is the TPU film. The limiter 4 is adjusted to move up and down to cooperate with the winding roller 3 to achieve high winding quality and average force on the TPU. The motor 6 rotates the winding roller 3 through the pulley 7. When the winding roller 3 rotates, the diameter becomes larger. At this time, the height of the limiter 4 and the height distance between the limiter 4 and the winding roller 3 are adjusted so that the TPU winding roller 3 can cooperate with the winding roller 3 to wind the TPU anytime and anywhere, thereby achieving stable winding quality and preventing the occurrence of uneven force on the TPU due to looseness and tightness.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
