Description

Technical Field

[0001] This utility model relates to the field of fabric conveying technology, specifically to a fabric conveying device for a buttoning machine. Background Technology

[0002] A button attaching machine is a specialized piece of equipment used to attach metal buttons, buckles, eyelets, and other accessories to clothing, shoes, hats, and leather products. It is suitable for industries such as denim, bags, and sportswear, and is widely used in garment factories and leather bag processing enterprises.

[0003] Existing fabric belts are designed to restrict their movement during fastening to prevent displacement. For example, utility model patent CN214140858U discloses a fabric belt conveyor for a fastening machine. This device uses a T-shaped pull rod to compress a strip-shaped arc-shaped abutment block and a pressure spring, placing the fabric belt on the conveyor belt and passing it through a U-shaped plate. Releasing the T-shaped pull rod causes the pressure spring to bring the strip-shaped arc-shaped abutment block into contact with the fabric belt, effectively limiting its movement and preventing displacement during transport. However, this existing technology has the following problems: Limiting the fabric belt during transport is achieved solely through the strip-shaped arc-shaped abutment block and a leveling roller pressing down on the fabric belt. If the fabric belt is folded, the strip-shaped arc-shaped abutment block and the leveling roller cannot unfold the fabric belt, affecting the actual fastening quality. Utility Model Content

[0004] The purpose of this utility model is to provide a fabric conveying device for a buttoning machine, which solves the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] A fabric conveying device for a buttoning machine includes a frame, on which a conveying device for conveying fabric and a buttoning machine body for buttoning the fabric are provided. Clamping and fixing components are provided on both sides of the frame, a lifting device is provided on one side of the buttoning machine body, a roller leveling component is provided at the bottom of the lifting device, and a roller pressing component connected to the frame is provided above the conveying device.

[0007] Before the fabric belt is fastened, the two clamping and fixing components clamp and fix both sides of the fabric belt respectively, and the fabric belt is flattened by the roller flattening component. The roller flattening component is used to flatten the fabric belt during the fabric belt conveying process and can rotate in the opposite direction of the fabric belt conveying direction.

[0008] As a preferred embodiment of this utility model, the clamping and fixing assembly includes a vertical plate disposed on one side of the frame. The vertical plate is provided with a screw and a plurality of pressure rollers, and the plurality of pressure rollers are rotatably arranged on the vertical plate at equal intervals in the horizontal direction and are all in contact with the lower surface of the inner side of the conveying device. A pressure plate that is slidably connected to the vertical plate is threaded onto the screw.

[0009] As a preferred embodiment of this utility model, the lower surface of the pressure plate is provided with a rubber layer.

[0010] As a preferred embodiment of the present invention, the roller leveling assembly includes a connecting plate rotatably disposed at the bottom of the lifting device via a torsion spring, and the connecting plate is inclined, with a pressure roller rotatably connected to the connecting plate.

[0011] In a preferred embodiment of this invention, the length of the pressure roller is greater than the width of the fabric strip.

[0012] As a preferred embodiment of the present invention, the roller pressing assembly includes a bracket mounted on a frame, a telescopic device that extends and retracts in the vertical direction on the bracket, a connecting seat at the bottom of the telescopic device, a leveling roller rotatably connected to the connecting seat, and a driving device connected to one end of the leveling roller, the driving device being mounted on the connecting seat.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention uses a conveying device to transport a fabric strip to the buttoning machine body for buttoning. The two sides of the fabric strip are fixed by a clamping and fixing component. Then, the fabric strip is rolled by a roller flattening component and pushed in the opposite direction of the fabric strip conveying direction by the roller pressing component. This allows the fabric strip to be fully unfolded during buttoning without any folds, thus improving the buttoning quality of the fabric strip. Attached Figure Description

[0022] 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.

[0023] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, this utility model provides a fabric tape conveying device for a buttoning machine, including a frame 1, a conveying device 2 for conveying fabric tape and a buttoning machine body 3 for buttoning the fabric tape on the frame 1, clamping and fixing components 4 on both sides of the frame 1, a lifting device 5 on one side of the buttoning machine body 3, a roller leveling component 6 at the bottom of the lifting device 5, and a roller pressing component 7 connected to the frame 1 above the conveying device 2.

[0025] Before the fabric belt is fastened, two clamping and fixing components 4 clamp and fix both sides of the fabric belt respectively, and the fabric belt is flattened by the roller flattening component 6. The roller pressing component 7 is used to press the fabric belt during the fabric belt conveying process and can rotate in the opposite direction of the fabric belt conveying direction.

[0026] In use, the fabric belt is placed on the conveying surface of the conveying device 2 (existing technology, such as belt conveyor, etc., the technical principle will not be elaborated in detail), and conveyed to the buttoning machine body 3 by the conveying device 2 for buttoning. The roller pressing component 7 flattens the fabric belt during the conveying process to ensure the flatness of the fabric belt.

[0027] When the fabric strip is conveyed to the button-fastening machine body 3, the conveying device 2 stops conveying the fabric strip. At the same time, the two clamping and fixing components 4 clamp and fix the two sides of the fabric strip respectively, so that the part of the fabric strip on one side of the button-fastening machine body 3 is fixed. Then, the lifting device 5 drives the roller flattening component 6 to move downward until it comes into contact with the fabric strip, so as to roll the fabric strip flat. Then, the roller pressing component 7 rotates in the opposite direction, so that the surface of the fabric strip is subjected to the friction force of the roller pressing component 7. With one end of the fabric strip fixed and the other end pushed in the opposite direction by friction, the fabric strip is in a completely flat and spread-out state, avoiding the problem of wrinkles or stacking of the fabric strip that would affect the button-fastening quality.

[0028] The clamping and fixing assembly 4 includes a vertical plate 401 disposed on one side of the frame 1. The vertical plate 401 is provided with a screw 402 and a plurality of pressure rollers 403. The plurality of pressure rollers 403 are arranged at equal intervals in the horizontal direction on the vertical plate 401 and are all in contact with the lower surface of the inner side of the conveying device 2. A pressure plate 404 is threadedly connected to the screw 402 and is slidably connected to the vertical plate 401.

[0029] A rubber layer is provided on the lower surface of the pressure plate 404.

[0030] When the clamping and fixing assembly 4 is in use, the pressure roller 403 is always in contact with the lower surface of the inner side of the conveying device 2 (e.g., the lower surface of the conveyor belt on a belt conveyor) to provide support. Then, the drive mechanism, such as a motor, drives the screw 402 to move the pressure plate 404 downward to abut against the fabric belt, so that the fabric belt is pressed against the conveying device 2. Thus, the fabric belt is fixed to the conveying device 2 by the two pressure plates 404, so that the fabric belt will not move in the reverse direction when the roller pressing assembly 7 rotates in the reverse direction.

[0031] The rubber layer is provided to protect the fabric strip and increase the friction between the pressure plate 404 and the fabric strip, thereby further improving the stability of the fabric strip when it is fixed.

[0032] The roller leveling assembly 6 includes a connecting plate 601 rotatably mounted at the bottom of the lifting device 5 via a torsion spring, and the connecting plate 601 is inclined. A pressure roller 602 is rotatably connected to the connecting plate 601.

[0033] The length of the pressure roller 602 is greater than the width of the fabric strip.

[0034] When the fabric strip is fixed by the clamping and fixing assembly 4, the lifting device 5 drives the connecting plate 601 to move downward until the pressure roller 602 abuts against the surface of the fabric strip. Since the connecting plate 601 is in an inclined state, as the connecting plate 601 continues to move downward, the pressure roller 602 moves along the surface of the fabric strip in the opposite direction to the fabric strip conveying direction. At the same time, the connecting plate 601 rotates and compresses the torsion spring, while the pressure roller 602 moves away from the pressure plate 404. Thus, the fabric strip is rolled by the movement of the pressure roller 602 to make the fabric strip unfold.

[0035] The length of the pressure roller 602 needs to be longer than the fabric strip to ensure that the surface of the fabric strip is spread out by the force of the pressure roller 602.

[0036] The roller pressing assembly 7 includes a support 701 mounted on the frame 1. The support 701 is provided with a telescopic device 702 that extends and retracts in the vertical direction. The bottom of the telescopic device 702 is provided with a connecting seat 703. A leveling roller 704 is rotatably connected to the connecting seat 703. One end of the leveling roller 704 is connected to a driving device, which is mounted on the connecting seat 703.

[0037] During normal conveying of the fabric belt, the telescopic device 702 drives the connecting seat 703 to move downward until the leveling roller 704 contacts the surface of the fabric belt, so that the fabric belt is continuously pressed down by the leveling roller 704 during the conveying process, keeping the fabric belt in a flat state.

[0038] When the fabric belt stops conveying and is ready to be fastened, the drive device (existing technology, such as a motor) drives the leveling roller 704 to rotate in the opposite direction. The friction between the leveling roller 704 and the fabric belt drives the fabric belt to move in the opposite direction of the fabric belt conveying direction, thereby unfolding the wrinkles and folds on the fabric belt and ensuring the fastening quality of the fabric belt.

[0039] In this embodiment, both the lifting device 5 and the telescopic device 702 are existing technologies, such as electric push rods or hydraulic push rods, and their technical principles will not be elaborated in detail here.

[0040] Furthermore, a sliding column can be provided on the connecting seat 703, and a sliding sleeve connected to the telescopic device 702 can be slidably sleeved on the sliding column. A spring that abuts against the end of the sliding sleeve is sleeved on the sliding column, which allows the leveling roller 704 to compress the spring and deform when it comes into contact with the fabric belt, thereby allowing the leveling roller 704 to fully contact the fabric belt to level the fabric belt.

[0041] The embodiments and / or implementation methods described above are merely preferred embodiments and / or implementation methods for implementing the present utility model, and are not intended to limit the implementation methods of the present utility model in any way. Any person skilled in the art can make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in the present utility model, but these should still be regarded as the same technology or embodiment as the present utility model.

[0042] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of this application.
