Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machines, specifically to rubber guide rollers for smooth fabrics. Background Technology

[0002] A fabric spreading machine is a device that flattens and lays out layers of rolled fabric. It mainly includes a spreading bed, a feeding mechanism, a pressing mechanism, and a spreading mechanism. After the feeding mechanism conveys the fabric to the spreading bed, the spreading mechanism clamps and moves the fabric to the spreading bed. After moving a set distance, the spread fabric is cut so that it can be laid out on the spreading bed. This process is repeated to lay out layers of the flattened fabric.

[0003] For example, our company's patent with authorization announcement number CN116675040B discloses a fabric spreading machine that facilitates fabric loading. It mainly includes a host computer, a fabric bed, a slide, a frame, a feeding mechanism, a tension adjustment mechanism, a fabric clamping mechanism, and a fabric feeding mechanism. The host computer integrates a control system that enables human-machine interaction. The fabric bed is used to place the folded fabric and also serves as the base of the equipment. The slide is installed on the upper side of the fabric bed and can drive the frame to move back and forth to achieve the fabric spreading action. The frame can move laterally. The fabric feeding roller and pressing roller installed in the machine can realize the conveying of the fabric. The feeding mechanism is installed at the rear end of the frame and can realize the feeding of rolls of fabric through the mechanical arm structure. The tension adjustment mechanism is installed inside the frame and can dynamically adjust the tension of the fabric to ensure uniform tension of the fabric throughout the laying process. The fabric clamping mechanism is fixedly installed at the front end of the laying bed and can realize the stable clamping of the fabric end and the firm pressing of the laid fabric. The fabric feeding mechanism is installed on the slide stand and can send the fabric end to the clamping mechanism for clamping.

[0004] The fabric feeding machine in the aforementioned patent mainly uses a feeding roller to transport the fabric during the feeding process. The feeding roller is covered with a layer of rubber material on its outer side to increase the friction between it and the fabric. However, during use, some particularly smooth fabrics are prone to slipping between the fabric and the feeding roller during transport, resulting in poor performance.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a rubber guide roller for smooth fabrics to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rubber guide roller for smooth fabrics includes a roller shaft, a metal roller, and a rubber sleeve. The metal roller is a cylindrical shape with openings at both ends, and the two ends of the metal roller are fixedly connected to the roller shaft through plugs. The metal roller has openings at both ends, and a rubber sleeve is fitted on the outer wall of the metal roller. The rubber sleeve and the metal roller are tightly fitted. The side wall of the rubber sleeve has several protrusions evenly distributed, and the protrusions are triangular pyramidal in shape. The triangular pyramidal protrusions are inclined to one side, and the top of the protrusions is not rounded to prevent scratching the fabric.

[0009] Furthermore, the inner wall of the end opening of the metal roller is provided with an abutting stepped groove, and the inner end of the plug abuts against the end of the abutting stepped groove.

[0010] Furthermore, a through hole is provided at the center of the plug for the roller shaft to pass through; a shoulder is provided on the roller shaft near the inner side of the through hole, and a retaining spring groove is provided on the roller shaft near the outer side of the through hole, a retaining spring is engaged in the retaining spring groove, and the inner side of the retaining spring abuts against the plug.

[0011] Furthermore, the roller shaft has square ends for fixing to the transmission components.

[0012] Furthermore, a limiting ring is provided at the outer end of the plug, wherein the limiting ring is grounded with the end of the rubber sleeve, thereby preventing the rubber sleeve from coming off from both ends of the metal roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The rubber sleeve with special protrusions fitted on the outside of the metal roller can significantly increase the friction between the roller and the fabric (especially the smooth-surfaced fabric), effectively reducing slippage during the conveying process and ensuring stable operation.

[0015] The rounded transition design at the top of the raised section also prevents scratches on the fabric.

[0016] The rubber sleeve and metal roller are connected by a tight fit. This design ensures a secure connection and facilitates replacement of the rubber sleeve after wear, reducing maintenance costs. The inclined triangular pyramidal protrusions further optimize the traction performance of the guide roller. Attached Figure Description

[0021] Please see Figure 1-3 A rubber guide roller for smooth fabric includes a roller shaft 1, a metal roller 2, and a rubber sleeve 3. The metal roller 2 is a cylindrical shape with openings at both ends. The two ends of the metal roller 2 are fixedly connected to the roller shaft 1 through plugs 4. The metal roller 2 has openings at both ends, and the inner wall of the opening at the end of the metal roller 2 is provided with an abutment stepped groove 201. The inner end of the plug 4 abuts against the end of the abutment stepped groove 201. At the same time, a through hole 401 is opened at the center of the plug 4 for the roller shaft 1 to pass through. The roller shaft 1 has a shoulder 101 near the inner side of the through hole 401, and a retaining spring groove 102 is provided near the outer side of the through hole 401. A retaining spring 103 is engaged in the retaining spring groove 102, and the inner side of the retaining spring 103 abuts against the plug 4.

[0022] In this invention, the plug 4 is fixed to the roller shaft 1 by a shoulder and a retaining spring, and the two symmetrically arranged plugs 4 are then fixed to the metal roller 2.

[0023] In this design, square heads 104 are provided at both ends of the roller 1 for fixing to the transmission components.

[0024] The outer wall of the metal roller 2 is fitted with a rubber sleeve 3, which is tightly fitted to the metal roller 2. The side wall of the rubber sleeve 3 is evenly provided with a plurality of protrusions 301, and the protrusions 301 are triangular pyramidal in shape and tilted to one side. In this design, the top of the protrusions 301 is not rounded to prevent scratching the fabric.

[0025] In this scheme, a limiting ring 402 is also provided at the outer end of the plug 4, wherein the limiting ring 402 is grounded with the end of the rubber sleeve 3, thereby preventing the rubber sleeve from coming off from both ends of the metal roller 2; the outer diameter of the limiting ring 402 should be greater than the outer diameter of the metal roller 2 and smaller than the outer diameter of the rubber sleeve.

[0026] When this utility model is used, the rubber sleeve 3 is put on the metal roller 2. During conveying, the rubber sleeve 3 with protrusions 301 can increase the friction with the fabric, thereby facilitating the conveying of fabric with a smooth surface and reducing the phenomenon of slippage between the rubber guide roller and the fabric.
