Description

Technical Field

[0001] The utility model relates to the technical field of cotton quilt quilting machines, in particular to an electrostatic elimination cloth guiding roller group for a cotton quilt quilting machine. Background Technique

[0002] A cotton quilt quilting machine is a device specifically used in the production process of cotton quilts. Its main function is to fix and reinforce multiple layers of fabrics through a stitching process to form a soft and warm cotton quilt. Such machines usually integrate advanced sewing technologies and can complete precise stitching operations at high speeds. One of the core components of a cotton quilt quilting machine is the cloth guiding roller group, which is responsible for smoothly conveying the fabric during the stitching process. The cloth guiding roller group not only ensures the smooth flow of the fabric but also provides the necessary tension and support during stitching. However, in actual operation, the fabric often moves unstably during transportation due to friction and the generation of static electricity. This problem not only affects the stitching accuracy but also may cause wrinkles and adhesions of the fabric, thereby reducing production efficiency and the quality of the finished product.

[0003] The patent with the publication number CN205602806U discloses an electrostatic elimination cloth guiding frame, which includes a reciprocating swing frame-shaped cloth guiding frame. An upper cloth guiding roller and a lower cloth guiding roller assembly are fixed on the cloth guiding frame. The feature is that a cross bar parallel to the upper cloth guiding roller and the lower cloth guiding roller assembly is fixed on the cloth guiding frame between the upper cloth guiding roller and the lower cloth guiding roller assembly. An electrostatic elimination rod is fixed on the cross bar. The electrostatic elimination rod contacts the fabric, and the length of the electrostatic elimination rod covers the width of the fabric passing through the cloth guiding frame. The electrostatic elimination rod is connected to an electrostatic eliminator. When the fabric passes through the cloth guiding frame, the fabric is always in contact with the electrostatic elimination rod, which eliminates the static electricity on the fabric. It has a simple structure, installs an electrostatic elimination device on the original cloth guiding frame, has good versatility, low price, and is easy to install, eliminating the harm brought by static electricity to the factory and workers.

[0004] The above-mentioned prior art eliminates static electricity by the way of the electrostatic elimination rod contacting the fabric. However, the electrostatic elimination rod is clamped and fixed on the cross bar through four U-shaped cards and bolts. Due to the fixed installation of the electrostatic elimination rod, during the transportation of the fabric, the electrostatic elimination rod will increase the friction of the fabric transportation. In addition, due to continuous friction with the fabric, the electrostatic elimination rod is easily worn, affecting its service life and efficiency. Therefore, aiming at the deficiencies of the prior art, we propose an electrostatic elimination cloth guiding roller group for a cotton quilt quilting machine, aiming to reduce friction and improve the electrostatic elimination effect through optimized design, thereby enhancing the stability of fabric transportation. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electrostatic elimination cloth guiding roller group for a cotton quilt quilting machine to solve the problems raised in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] The static elimination cloth guiding roller group of a cotton quilt quilting machine includes a base. As shown in combination Figures 1-5 shown, a cloth guiding member, an electrostatic elimination component, and a cloth conveying component are successively arranged on the top of the base from left to right. The cloth guiding member is used to guide and preliminarily position the conveying path of the cloth to be processed. The electrostatic elimination component is used to eliminate the static charges on the surface of the cloth. The cloth conveying component is used for final output;

[0008] The electrostatic elimination component includes two second brackets arranged symmetrically front and back. A fixed support tube is jointly connected to the tops of the two second brackets, which is used to fix the conductive rod and provide a rotational connection basis for the conductive roller. A conductive rod is arranged in the fixed support tube, and charge conduction is realized by contacting with a conductive brush. A plurality of conductive brushes are arranged at equal distances front and back on the top of the outer wall of the conductive rod, which are used to connect the conductive rod and the conductive roller to form a conductive path. A grounding wire is arranged at the front end of the conductive rod, which is used to introduce the static charges into the ground to complete the elimination. A conductive roller is rotatably connected to the outside of the fixed support tube, which contacts the cloth by rotation and adsorbs static electricity to avoid wear of the fixed friction surface. The conductive roller is of a circular tube structure. Both the conductive rod and the conductive roller are made of copper material to ensure high conductivity. One end of the conductive brush far from the conductive rod contacts the inner wall of the conductive roller;

[0009] A plurality of connecting rods arranged in an annular array are respectively arranged at positions near the front and rear ends of the inner wall of the conductive roller, which are used to fix the annular connecting block and disperse the force of the conductive roller. One end of the plurality of connecting rods arranged in an annular array far from the conductive roller is jointly connected to an annular connecting block. The annular connecting block is connected to the outer wall of the fixed support tube through a bearing, so that the conductive roller can rotate around the fixed support tube.

[0010] Preferably, as shown in Figure 1 shown, the cloth guiding member includes two first brackets arranged symmetrically front and back. An input guide roller is jointly rotatably connected to the tops of the two first brackets, which is used to reduce the frictional resistance when the cloth is introduced and ensure smooth initial conveying.

[0011] Preferably, as shown in Figure 5 shown, a strip-shaped avoidance opening is opened at the top of the outer wall of the fixed support tube. The rear end of the strip-shaped avoidance opening is of an open structure. The conductive brush passes through the strip-shaped avoidance opening, which provides an installation and avoidance space for the conductive brush to avoid structural interference.

[0012] Preferably, as shown in Figure 6As shown in the figure, the fabric conveying assembly includes two third brackets arranged symmetrically front and back. The bottoms of the first bracket, the second bracket and the third bracket are all installed on the top of the base by bolts. The tops of the two third brackets are jointly rotatably connected with an output guide roller for driving the fabric to be output to the cotton quilt quilting machine. A motor for driving the output guide roller to rotate is arranged outside one of the third brackets, which works with an external power supply and a controller to provide a power source to realize the active rotation of the output guide roller;

[0013] A cross plate is arranged between the two third brackets and at the middle and lower part for installing an electric cylinder. The middle of the bottom of the cross plate is provided with an electric cylinder, which works with an external power supply and a controller. The movable rod of the electric cylinder passes through the bottom of the cross plate and is fixedly connected with a movable support plate. The height of the guide roller is adjusted by telescoping the movable rod, so that the fabric is clamped between the guide roller and the output guide roller, and then the output guide roller drives the fabric to be output. The front and rear sides of the movable support plate are respectively attached to the opposite side surfaces of the two third brackets, so that the movable support plate moves stably up and down;

[0014] Two movable vertical rods arranged symmetrically front and back are arranged through the top of the movable support plate for supporting the U-shaped plate and restricting its vertical movement. The tops of the two movable vertical rods are jointly connected with a U-shaped plate. A guide roller is rotatably connected between the front and rear sides of the inner wall of the U-shaped plate. The guide roller is located directly below the output guide roller, and the guide roller cooperates with the output guide roller to output the fabric;

[0015] A spring is sleeved outside the movable vertical rod. The bottom end of the spring abuts against the top of the movable support plate, and the top end of the spring abuts against the bottom of the U-shaped plate, avoiding excessive extrusion of the fabric and being beneficial to the output of the fabric by the guide roller cooperating with the output guide roller.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. For the static electricity elimination fabric guiding roller group of this cotton quilt quilting machine, a rotatable conductive roller is used instead of a fixed static electricity elimination rod, which reduces the direct friction with the fabric while eliminating static electricity, avoids component wear and fabric damage caused by fixed friction, and significantly prolongs the service life of the equipment.

[0018] 2. For the static electricity elimination fabric guiding roller group of this cotton quilt quilting machine, a continuous conduction path is formed through the conductive rod, the conductive brush and the grounding wire. The high conductivity of the copper material is used to quickly transfer the static charge on the fabric surface to the ground, ensuring stable static electricity elimination effect and avoiding fabric adhesion or displacement caused by static electricity accumulation.

[0029] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0030] The static elimination fabric guiding roller group of the cotton quilt quilting machine includes a base 100. Combining Figures 1-5 as shown, a fabric guiding member 200, an electrostatic elimination component 300, and a fabric conveying component 400 are sequentially arranged on the top of the base 100 from left to right. The fabric guiding member 200 is used to guide and preliminarily position the conveying path of the fabric to be processed. The electrostatic elimination component 300 is used to eliminate the static charges on the surface of the fabric. The fabric conveying component 400 is used for final output;

[0031] The electrostatic elimination component 300 includes two second brackets 310 arranged symmetrically front and back. The tops of the two second brackets 310 are commonly connected with a fixed support tube 320, which is used to fix the conductive rod 330 and provide a rotational connection basis for the conductive roller 360. A conductive rod 330 is arranged inside the fixed support tube 320, and charge conduction is achieved through contact with the conductive brush 340. A plurality of conductive brushes 340 arranged at equal distances front and back are provided on the top of the outer wall of the conductive rod 330, which are used to connect the conductive rod 330 and the conductive roller 360 to form a conduction path. A ground wire 350 is provided at the front end of the conductive rod 330, which is used to conduct the static charges into the ground to complete the elimination. A conductive roller 360 is rotatably connected to the outside of the fixed support tube 320, which contacts the fabric by rotation and adsorbs static electricity to avoid wear of the fixed friction surface. The conductive roller 360 is of a circular tube structure. Both the conductive rod 330 and the conductive roller 360 are made of copper materials to ensure high conductivity. One end of the conductive brush 340 far from the conductive rod 330 contacts the inner wall of the conductive roller 360;

[0032] A plurality of connecting rods 361 arranged in an annular array are provided at positions near the front and rear ends of the inner wall of the conductive roller 360, which are used to fix the annular connection block 362 and disperse the force on the conductive roller 360. One end of the plurality of connecting rods 361 arranged in an annular array far from the conductive roller 360 are commonly connected with an annular connection block 362. The annular connection block 362 is connected to the outer wall of the fixed support tube 320 through a bearing, so that the conductive roller 360 can rotate around the fixed support tube 320.

[0033] In this embodiment, as Figure 1 shown, the fabric guide 200 includes two first brackets 210 arranged symmetrically front and back. The tops of the two first brackets 210 are jointly rotatably connected with an input guide roller 220, which is used to reduce the frictional resistance when the fabric is introduced and ensure stable initial conveying.

[0034] Specifically, as Figure 5 shown, a strip-shaped avoidance opening 321 is provided at the top of the outer wall of the fixed support pipe 320. The rear end of the strip-shaped avoidance opening 321 is an open structure. The conductive brush 340 passes through the strip-shaped avoidance opening 321, providing installation and avoidance space for the conductive brush 340 to avoid structural interference.

[0035] Furthermore, as Figure 6 shown, the fabric conveying assembly 400 includes two third brackets 410 arranged symmetrically front and back. The bottoms of the first bracket 210, the second bracket 310 and the third bracket 410 are all installed on the top of the base 100 by bolts. The tops of the two third brackets 410 are jointly rotatably connected with an output guide roller 420, which is used to drive the fabric to be output to the cotton quilt quilting machine. A motor 430 for driving the output guide roller 420 to rotate is provided on the outside of one of the third brackets 410. It works with an external power supply and a controller to provide a power source to realize the active rotation of the output guide roller 420;

[0036] A cross plate 411 is provided between the two third brackets 410 and at the middle and lower part, which is used to install the electric cylinder 440. The middle of the bottom of the cross plate 411 is provided with the electric cylinder 440. It works with an external power supply and a controller. The movable rod of the electric cylinder 440 passes through the bottom of the cross plate 411 and is fixedly connected with a movable support plate 450. The height of the guide roller 480 is adjusted by telescoping the movable rod, so that the fabric is clamped between the guide roller 480 and the output guide roller 420, so that the output guide roller 420 drives the fabric to be output. The front and rear sides of the movable support plate 450 are respectively attached to the opposite sides of the two third brackets 410, so that the movable support plate 450 moves stably up and down;

[0037] Two movable vertical rods 460 arranged symmetrically front and back penetrate through the top of the movable support plate 450. The movable vertical rods 460 can move up and down relative to the movable support plate 450, which is used to support the U-shaped plate 470 and limit its vertical movement. The tops of the two movable vertical rods 460 are jointly connected with the U-shaped plate 470. A guide roller 480 is rotatably connected between the front and rear sides of the inner wall of the U-shaped plate 470. The guide roller 480 is located directly below the output guide roller 420. The guide roller 480 cooperates with the output guide roller 420 to output the fabric;

[0038] A spring 490 is sleeved outside the movable vertical rod 460. The bottom end of the spring 490 abuts against the top of the movable support plate 450, and the top end of the spring 490 abuts against the bottom of the U-shaped plate 470, avoiding excessive extrusion of the fabric and facilitating the output of the fabric by the guiding roller 480 in cooperation with the output guiding roller 420.

[0039] When the static electricity eliminating fabric guiding roller group of the cotton quilt quilting machine in this embodiment is in use, the operator first feeds the fabric to be processed into the equipment through the input guiding roller 220 of the fabric guiding member 200. The input guiding roller 220 reduces the frictional resistance during fabric feeding by rotation to ensure smooth initial conveying. The fabric then enters the area of the static electricity eliminating component 300. The conductive roller 360 rotatably connected to the outside of the fixed support tube 320 contacts the surface of the fabric. Then the fabric passes between the guiding roller 480 and the output guiding roller 420. The electric cylinder 440 adjusts the height of the movable support plate 450 through the telescopic rod, so that the movable support plate 450 drives the movable vertical rod 460, the U-shaped plate 470 and the guiding roller 480 to move up and down. The spring 490 buffers the contact pressure between the guiding roller 480 and the output guiding roller 420 to ensure that the fabric maintains an appropriate tension between the output guiding roller 420 and the guiding roller 480, avoiding excessive extrusion or slipping. The conductive roller 360 rotates around the fixed support tube 320 driven by the fabric. A conductive path is formed through the contact between the conductive brush 340 and the conductive rod 330, and the static charges on the fabric surface are transferred to the ground wire 350 through the conductive rod 330 to achieve static electricity elimination. During this process, the connecting rod 361 and the annular connecting block 362 on the inner wall of the conductive roller 360 disperse the force through the bearing structure to ensure smooth and stable rotation of the conductive roller 360. The fabric after static electricity elimination enters the fabric conveying component 400, and the output guiding roller 420 is driven to rotate actively by the motor 430 to drive the fabric to be output, finally realizing continuous and stable conveying of the fabric from feeding, static electricity elimination to output.
