Technical Field

[0001] This utility model relates to a fabric trimming device that facilitates adjustment of the cutting spacing, and belongs to the field of fabric cutting technology. Background Technology

[0002] In existing fabric manufacturing processes, the edges of the fabric need to be trimmed to remove lint and uneven areas. Since the width of the fabric varies, the required trimming width differs. This necessitates adjusting the position of the cutting blades in the trimming device. However, in existing devices, both blades are limited by bolts passing through them and being held against mounting rods. Adjustment requires adjusting both blades, which is cumbersome. Therefore, this invention proposes a fabric trimming device with easily adjustable cutting spacing. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a fabric trimming device that facilitates adjustment of the cutting spacing, thereby solving the problems in the background art.

[0004] This utility model provides the following technical solution:

[0005] A fabric trimming device for easy adjustment of cutting spacing includes a base plate. A set of first upright plates are symmetrically arranged at the top center of the base plate. Cutting rollers are rotatably connected between the set of first upright plates. The rear end shafts of the cutting rollers extend through the first upright plates. A motor is mounted on the rear end face of each of the first upright plates, and the motor output shaft is connected to the roller shaft of the cutting rollers. A set of symmetrical U-shaped plates is arranged above the cutting rollers between the set of first upright plates. A support plate is located in the middle of the U-shaped plates. A groove is formed between the top and bottom of the adjacent ends of the U-shaped plates. A bidirectional screw is rotatably connected to the support plate. The threaded rod has movable plates threadedly connected to the threaded portions on both sides. Connecting plates are located at the center of the upper and lower end faces of the movable plates. The connecting plates slide against the sliding groove. A cutter seat is fixedly connected to the end of the connecting plate away from the movable plate. The cutter seat is slidably sleeved on a set of U-shaped plates. A ring cutter is rotatably connected to the cutter seat. The ring cutter is tangential to the cutting roller. A rotating shaft is rotatably connected to the upper end of the first vertical plate at the front end of the base plate and the rotating connection part of the cutting roller. The rotating shaft is inserted into one end of the threaded rod. A handwheel is located at the end of the rotating shaft away from the threaded rod.

[0006] Preferably, the U-shaped plate is provided with ear plates at both ends, and the ear plates are detachably fixed to the inner side of the first upright plate by bolts.

[0007] Preferably, the outer surface of the U-shaped plate on one side is provided with scale lines.

[0008] Preferably, auxiliary rollers are rotatably connected to the left and right sides of the lower end of the cutting roller between the first set of vertical plates, and the auxiliary rollers are symmetrically arranged.

[0009] Preferably, a set of second vertical plates is symmetrically provided at the top left end of the base plate, and a set of first limiting rollers are rotatably connected between the set of second vertical plates.

[0010] Preferably, a set of third vertical plates is symmetrically provided at the top right end of the base plate, and a set of second limiting rollers are rotatably connected between the set of third vertical plates.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention provides a fabric trimming device for easy adjustment of the cutting spacing. By incorporating a handwheel and a rotating shaft, with the shaft connected to a bidirectional threaded rod, the handwheel can synchronously drive the bidirectional threaded rod to rotate forward or backward. When the bidirectional threaded rod rotates forward, it drives the moving plates closer together, which in turn drives the cutter holders connected by the connecting plate closer together, thus increasing the cutting spacing. When the bidirectional threaded rod rotates backward, it drives the moving plates further apart, which in turn drives the cutter holders connected by the connecting plate further apart, thus decreasing the cutting spacing. This achieves synchronous adjustment of the two annular cutters, making adjustment more convenient and faster compared to traditional methods. Attached Figure Description

It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0020] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0022] like Figures 1-4As shown, a fabric trimming device for easy adjustment of cutting spacing includes a base plate 1. A set of first upright plates 2 are symmetrically arranged at the top center of the base plate 1. Cutting rollers 3 are rotatably connected between the set of first upright plates 2. The rear end roller shaft of the cutting rollers 3 passes through the first upright plates 2. A motor 4 is provided on the rear end face of the rear end of the first upright plates 2. The output shaft of the motor 4 is connected to the roller shaft of the cutting rollers 3. A set of symmetrical U-shaped plates 5 are provided above the cutting rollers 3 between the set of first upright plates 2. A support plate 6 is provided in the middle of the set of U-shaped plates 5. A groove 7 is formed between the top and bottom of the adjacent ends of the set of U-shaped plates 5. A bidirectional threaded rod 8 is rotatably connected to the support plate 6. Moving plates 9 are threadedly connected to the threaded portions on both sides of the threaded rod 8. Connecting plates 10 are provided at the center of the upper and lower end faces of the moving plates 9. The connecting plates 10 are slidably engaged with the sliding groove 7. A cutter seat 11 is fixedly connected to the end of the connecting plate 10 away from the moving plates 9. The cutter seat 11 is slidably sleeved on a set of U-shaped plates 5. An annular cutter 12 is rotatably connected to the cutter seat 11. The annular cutter 12 is tangent to the cutting roller 3. A rotating shaft 13 is rotatably connected to the upper end of the first vertical plate 2 at the front end of the base plate 1 and the rotatable connection part of the cutting roller 3. The rotating shaft 13 is inserted into one end of the bidirectional threaded rod 8. A handwheel 14 is provided at the end of the rotating shaft 13 away from the bidirectional threaded rod 8.

[0023] In the above technical solution, by setting a handwheel 14 and a rotating shaft 13, and connecting the rotating shaft 13 to the bidirectional threaded rod 8, the forward and reverse handwheel 14 can synchronously drive the bidirectional threaded rod 8 to rotate forward or reverse. When the bidirectional threaded rod 8 rotates forward, it drives the moving plates 9 to move closer together, which in turn drives the cutter holders 11 connected by the connecting plate 10 to move closer together, thus increasing the cutting distance. When the bidirectional threaded rod 8 rotates reverse, it drives the moving plates 9 to move away from each other, which in turn drives the cutter holders 11 connected by the connecting plate 10 to move away from each other, thus decreasing the cutting distance. This achieves the function of synchronous adjustment of the two annular cutters 12, which is more convenient and faster than the traditional adjustment method.

[0024] It is worth noting that the cutting distance mentioned in this utility model refers to the distance between the annular cutter 12 and the inner side of the first upright plate 2.

[0025] In this utility model, the U-shaped plate 5 is provided with ear plates 15 at both ends, and the ear plates 15 are detachably fixed to the inner side of the first upright plate 2 by bolts.

[0026] In the above technical solution, a set of U-shaped plates 5 are fixed between a set of first upright plates 2 by using bolts to pass through the ear plate 15 and fix it to the first upright plate 2, so that a set of U-shaped frames can be disassembled, which facilitates the replacement and maintenance of the annular cutter 12, the cutter seat 11 and the bidirectional threaded rod 8.

[0027] In this utility model, a scale line 16 is provided on the outer surface of the U-shaped plate 5 on one side.

[0028] In this utility model, auxiliary rollers 17 are rotatably connected to the left and right sides of the lower end of the cutting rollers 3 between the first set of vertical plates 2, and the auxiliary rollers 17 are symmetrically arranged.

[0029] In the above technical solution, by setting auxiliary rollers 17, when the fabric passes through the gap between a set of auxiliary rollers 17 and the cutting roller 3, the fabric can be stretched taut on the cutting roller 3, which can prevent the fabric from wrinkling during the cutting process and is beneficial for edge trimming.

[0030] In this utility model, a set of second vertical plates 18 are symmetrically provided at the top left end of the base plate 1, and a set of first limiting rollers 19 are rotatably connected between the set of second vertical plates 18.

[0031] In this utility model, a set of third vertical plates 20 are symmetrically provided at the top right end of the base plate 1, and a set of second limiting rollers 21 are rotatably connected between the set of third vertical plates 20.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
