Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, and specifically relates to a tensioning mechanism for a shearing machine. Background Technology

[0002] A shearing machine is a specialized piece of equipment used to remove fuzz or loose fibers from the surface of fabrics. It is widely used in textile finishing processes to improve the smoothness, evenness, and texture of fabric surfaces by cutting off excess fibers or fuzz, making the fabric surface smoother. The shearing machine is a key piece of equipment for improving fabric quality. During the use of the shearing machine, the tension between the fabrics is adjusted through a tensioning mechanism.

[0003] The existing tensioning mechanism of a shearing machine involves placing the fabric to be sheared between guide rollers. The rotation of the guide rollers moves the fabric. When tension is needed, it is adjusted by springs, counterweights, or a manual screw to achieve the desired tension for shearing. However, in actual use, when tension needs to be adjusted, the position of the counterweight or the screw needs to be manually adjusted, which is time-consuming and labor-intensive. Different types of fabrics require different tensions, and adjustments may introduce errors, resulting in inaccurate tension and affecting the shearing effect of the shearing machine. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a tensioning mechanism for a shearing machine, which can quickly and accurately control the distance between the tensioning roller and the drive seat, thereby accurately and stably controlling the tension force between the tensioning rollers and effectively ensuring the shearing effect of the shearing machine.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tensioning mechanism for a shearing machine, including a frame, a tensioning seat provided on the upper surface of the frame, a drive seat provided inside the tensioning seat, a plurality of slide cylinders provided on the outer side of the drive seat, a slide rod slidably provided inside each slide cylinder, an L-shaped seat provided at the end of each slide rod away from the slide cylinder, a tensioning roller rotatably provided between adjacent L-shaped seats, a symmetrically distributed drive rollers provided inside the frame, a guide roller provided on the upper side of each drive roller, and a fabric provided between the guide roller, drive roller and tension roller; a plurality of fixing plates provided on the lower surface of the frame, and a rubber pad glued and fixed to the lower surface of each fixing plate.

[0006] As a further improvement of this utility model, a drive module is provided inside the drive seat. The drive module is used to adjust the tension between the tensioning rollers. The drive module includes an adjusting screw that is rotatably disposed inside the slide cylinder. The adjusting screw is threadedly connected to the adjacent slide rods. The tension seat has symmetrically distributed rotating shafts rotatably disposed inside. Each rotating shaft is fixedly fitted with a bevel gear II. The end of the adjusting screw near the transverse center of the tension seat is fixedly fitted with a bevel gear I. Each bevel gear I is meshed with the adjacent bevel gear II. A dual-axis motor is disposed in the middle of the tension seat. The output shaft of the dual-axis motor is fixed to the adjacent rotating shaft through a coupling.

[0007] As a further improvement of this utility model, pulleys are fixedly sleeved on the front end of each drive roller, and a transmission belt is provided between the pulleys. A servo motor is provided on the outside of the frame, and the output shaft of the servo motor is fixed to the adjacent drive roller by a coupling.

[0008] As a further improvement of this utility model, a control box is provided on the frame, and the servo motor and the dual-axis motor are both connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the dual-axis motor is controlled by the control box to operate, causing the slide bar to move the tensioning roller closer to or away from the drive seat, thereby quickly and stably tensioning the fabric between the tensioning rollers.

[0011] Secondly, by using the meshing relationship between bevel gear two and bevel gear one and the thread relationship between the adjusting screw and the slide bar, the distance between the tensioning roller and the drive seat can be controlled quickly and accurately, thereby enabling accurate and stable control of the tension force between the tensioning rollers.

[0012] Third, the transmission belt, which is set between the pulleys, drives the drive rollers on both sides to rotate synchronously, and then the guide roller, drive roller and tension roller work together to achieve stable conveying of the fabric.

[0013] Fourth, during installation and fixing, the bolts are passed through the fixing plate and then tightened by external tools, which can effectively prevent the position of the frame from easily moving during the processing. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the machine includes a frame 101. A tensioning seat 103 is provided on the upper surface of the frame 101. A drive seat 201 is provided inside the tensioning seat 103. Multiple slide cylinders 202 are provided on the outer side of the drive seat 201. A slide rod 203 is slidably provided inside each slide cylinder 202. An L-shaped seat 204 is provided at the end of each slide rod 203 away from the slide cylinder 202. A tensioning roller 205 is rotatably provided between adjacent L-shaped seats 204. A drive roller 104 is symmetrically distributed inside the frame 101. A guide roller 105 is provided on the upper side of each drive roller 104. A fabric 108 is wound around the guide roller 105, drive roller 104 and tension roller 205 along the conveying direction.

[0022] like Figure 3 , 4As shown, a drive module is installed inside the drive seat 201. The drive module is used to adjust the tension between the tensioning rollers 205. The drive module includes an adjusting screw 206 rotatably installed inside the slide cylinder 202. The adjusting screw 206 is threadedly connected to the adjacent slide rod 203. The tension seat 103 has symmetrically distributed rotating shafts 208 rotatably installed inside. Each rotating shaft 208 is fixedly fitted with a second bevel gear 209. The end of the adjusting screw 206 near the transverse center of the tension seat 103 is fixedly fitted with a first bevel gear 207. The first bevel gear 207 is meshed with the adjacent second bevel gear 209. A dual-axis motor 210 is installed in the middle of the tension seat 103. The output shaft of the dual-axis motor 210 is fixed to the adjacent rotating shaft 208 by a coupling.

[0023] like Figure 1 As shown, pulleys 106 are fixedly sleeved on the front end of each drive roller 104, and a transmission belt 107 is provided between the pulleys 106. A servo motor is provided on the outside of the frame 101, and the output shaft of the servo motor is fixed to the adjacent drive roller 104 by a coupling.

[0024] like Figure 4 As shown, a control box 301 is installed on the frame 101, and the servo motor and the dual-axis motor 210 are both connected to the control box 301.

[0025] In use, the servo motor is controlled by the control box 301 to rotate, which drives the drive roller 104 connected to it to rotate. The transmission belt 107, which is connected between the pulleys 106, drives the drive rollers 104 on both sides to rotate synchronously. Then, the stable conveying of the fabric is achieved through the cooperation of the guide roller 105, the drive roller 104 and the tension roller 205.

[0026] When tension adjustment is required, the control box 301 controls the operation of the dual-axis motor 210, which in turn drives the rotating shaft 208 connected to it to rotate. The rotating shaft 208 drives the bevel gear 209 connected to it to rotate. Through the meshing relationship between the bevel gear 209 and the first bevel gear 207, the adjusting screw 206 rotates. Through the thread relationship between the adjusting screw 206 and the slide rod 203, the slide rod 203 slides against the slide cylinder 202. This causes the slide rod 203 to move the tension roller 205 closer to or away from the drive seat 201, thereby quickly and stably tensioning the fabric between the tension rollers 205. The meshing relationship between the bevel gear 209 and the first bevel gear 207 and the thread relationship between the adjusting screw 206 and the slide rod 203 can quickly and accurately control the distance between the tension roller 205 and the drive seat 201, thereby accurately and stably controlling the tension force between the tension rollers 205.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the lower surface of the frame 101 is provided with multiple fixing plates 102, and rubber pads are glued and fixed to the lower surface of each fixing plate 102. During installation and fixing, the bolts are passed through the fixing plates 102 and then tightened by external tools, which can effectively prevent the position of the frame 101 from easily moving during the processing.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
