Description

An unwinding machine

Technical Field

The present application relates to the field of textile equipment, and in particular to an unwinding machine.

Background Art

In the textile production process, it is necessary to unwind the rolled textile fabric, which requires the use of an unwinding machine.

Existing unwinding machines usually have rotating shafts at the head and tail. The rotating shaft at the tail is used to rotate the rolled textile cloth for unwinding, and the rotating shaft at the head is used to pull the unrolled textile cloth. The two rotating shafts are respectively connected to two corresponding motors, and the rotation of the rotating shafts is controlled by the motors to realize the rotation and unwinding of the rolled textile cloth. Since two motors are used, the power consumption is relatively large, which increases the production cost.

In view of this, a retarder is needed.

Utility Model Content

In order to improve the problem that the cost of the unwinding machine is relatively high due to the provision of two motors, the present application provides an unwinding machine.

The present application provides an unwinding machine, which adopts the following technical solution: an unwinding machine, comprising an active roller, a driven roller, a driven roller placement unit and an unwinding motor, wherein the unwinding motor and the active roller are drivingly connected to drive the active roller to rotate, the driven roller is wound with cloth to be unwound, the driven roller placement unit comprises a receiving portion and a pressing portion, the driven roller is placed on the receiving portion, the pressing portion is pressed on the driven roller, and the driven roller can rotate between the receiving portion and the pressing portion, and the cloth can pass through between the receiving portion and the pressing portion or pass through the pressing portion and be wound around the active roller.

By adopting the above technical solution, the active roller can be driven to rotate by the unwinding motor to realize the unwinding of the cloth on the driven roller. The driven roller is crimped between the receiving part and the crimping part so as to realize positioning. The driven roller can rotate between the receiving part and the crimping part, and can also provide tensioning force for the cloth in the unwinding process through the friction between the cloth on the driven roller and the crimping part and the receiving part, so that there is no need to set a motor to drive the driven roller to rotate, which can save costs.

Furthermore, the angular spacing between the receiving rollers gradually decreases from top to bottom.

By adopting the above technical solution, as the unwinding proceeds, when the cloth on the driven roller becomes smaller and smaller, the receiving portion can still provide good support to the driven roller and the cloth on the driven roller.

Furthermore, each of the receiving rollers is provided with a pair of lower limit retaining rings so as to stop the driven roller between the pair of lower limit retaining rings that are relatively arranged.

By adopting the above technical solution, it can be ensured that the driven roller and the cloth on the driven roller are not prone to shaking along the feeding direction perpendicular to the cloth on the receiving part, which can make the unwinding more stable.

By adopting the above technical solution, multiple crimping rollers can be used to abut against the driven roller, so that there is rolling friction between the driven roller and the crimping part, the friction force is small, and the cloth is not easily damaged. The structural design of the crimping frame can match the cylindrical driven roller, so that the driven roller can abut against the two highest crimping rollers on the crimping frame as much as possible in the crimping frame, so that it is not easy to be displaced, thereby facilitating the maintenance of the stability of the tensioning force.

Furthermore, each of the crimping rollers is provided with a pair of upper limit retaining rings, so as to be able to stop the driven roller between the pair of upper limit retaining rings that are arranged opposite to each other.

By adopting the above technical solution, it can be ensured that the driven roller and the cloth on the driven roller are not prone to shaking along the feeding direction perpendicular to the cloth on the receiving part, which can make the unwinding more stable.

Furthermore, an insertion hole suitable for inserting a pressure gauge is provided at the end of the crimping frame, and the inserted pressure gauge can contact the groove wall of the slide groove close to the active roller to detect the force of the end of the crimping frame on the groove wall.

By adopting the above technical solution, the tension of the cloth during the unwinding process can be detected in real time, so as to facilitate the subsequent adjustment of the tension.

Furthermore, a counterweight block can be inserted into the slide groove, and the counterweight block can apply a force toward the receiving frame to the end of the crimping frame.

By adopting the above technical solution, the friction between the cloth on the driven roller and the crimping part and the receiving part can be adjusted by inserting counterweights of different weights into the slide groove, thereby adjusting the tension of the cloth during the unwinding process.

In summary, the present application includes at least one of the following beneficial effects:

1. The unwinding motor can drive the active roller to rotate to realize the unwinding of the cloth on the driven roller. The driven roller is pressed between the receiving part and the pressing part so as to realize positioning.

2. The friction between the fabric on the driven roller and the crimping part and the receiving part can be adjusted by inserting counterweights of different weights into the slide groove, so that the tension of the fabric during the unwinding process can be adjusted.

Referring to Fig. 1 and Fig. 2, an unwinding machine provided by the present application includes an active roller 1, a driven roller 2, a placement unit of the driven roller 2 and an unwinding motor 4. The unwinding motor 4 is transmission-connected to the active roller 1 to drive the active roller 1 to rotate, and the cloth to be unwound is wound on the driven roller 2. The placement unit of the driven roller 2 includes a receiving portion 31 and a crimping portion 32. The driven roller 2 is placed on the receiving portion 31, and the crimping portion 32 is crimped on the driven roller 2, and the driven roller 2 can rotate between the receiving portion 31 and the crimping portion 32, and the cloth can pass through between the receiving portion 31 and the crimping portion 32 or pass through the crimping portion 32 and be wound around the active roller 1, so that when the unwinding motor 4 drives the active roller 1 to rotate, the cloth on the driven roller 2 can be unwound.

Through the above design, the driven roller 2 is crimped between the receiving portion 31 and the crimping portion 32 so as to achieve positioning. The driven roller 2 can rotate between the receiving portion 31 and the crimping portion 32, and can also provide tensioning force for the cloth in the unwinding process through the friction between the cloth on the driven roller 2 and the crimping portion 32 and the receiving portion 31, so there is no need to set a motor to drive the driven roller 2 to rotate, which can save costs.

FIG3 is a cross-sectional view taken along the A-A direction in FIG2 , and FIG4 is a cross-sectional view taken along the B-B direction in FIG2 . Referring to FIG3 and FIG4 , further, the active roller placement unit may further include a pair of support columns 33, and specifically, the receiving portion 31 includes a receiving frame 311 and a plurality of receiving rollers 312 disposed on the receiving frame 311, the ends of both ends of the receiving frame 311 are connected to the corresponding support columns 33, and the receiving frame 311 is recessed downward in a direction from away from the active roller 1 to close to the active roller 1, and each receiving roller 312 is rotatably connected to the receiving frame 311, and each receiving roller 312 The axial direction of the receiving roller 312 is parallel to that of the receiving roller 312, and the axial direction of the receiving roller 312 is perpendicular to the conveying direction of the cloth. The design of the receiving portion 31 can realize that a plurality of receiving rollers 312 are used to receive the driven roller 2, so that there is rolling friction between the driven roller 2 and the receiving portion 31, and the friction force is small, and it is not easy to damage the cloth. The structural design of the receiving frame 311 can match the cylindrical driven roller 2, so that the driven roller 2 in the receiving frame 311 can be in contact with the two lowest receiving rollers 312 on the upper part of the receiving frame 311 as much as possible, so as to prevent displacement, thereby facilitating the maintenance of the stability of the tensioning force.

Furthermore, the angular spacing between the receiving rollers 312 can be set to gradually decrease from top to bottom, so that as the unwinding proceeds, when the cloth on the driven roller 2 becomes smaller and smaller, the receiving portion 31 can still provide good support for the driven roller 2 and the cloth on the driven roller 2. In addition, each receiving roller 312 is provided with a pair of lower limit retaining rings 313, so that the driven roller 2 can be stopped between the pair of relatively arranged lower limit retaining rings 313, thereby ensuring that the driven roller 2 and the cloth on the driven roller 2 are not prone to shaking along the feeding direction perpendicular to the cloth on the receiving portion 31, making the unwinding more stable.

Furthermore, a slide groove 331 extending in the vertical direction can be opened on the support column 33, and the crimping portion 32 can be specifically configured to include a crimping frame 321 and a plurality of crimping rollers 322 arranged on the crimping frame 321, the ends of both ends of the crimping frame 321 are inserted into the corresponding slide grooves 331, and the crimping frame 321 protrudes upward in a direction from away from the active roller 1 to close to the active roller 1, and each crimping roller 322 is rotatably connected to the crimping frame 321, and the axial directions of each crimping roller 322 are parallel, and the axial directions of the crimping roller 322 are perpendicular to the conveying direction of the cloth. The structural setting of the crimping portion 32 can realize that the plurality of crimping rollers 322 abut against the driven roller 2, so that the driven roller 2 and There is rolling friction between the crimping parts 32, and the friction force is small, which is not easy to damage the cloth, and the structural design of the crimping frame 321 can match the cylindrical driven roller 2, so that the driven roller 2 can be in contact with the two highest crimping rollers 322 on the crimping frame 321 as much as possible in the crimping frame 321, so as to be less likely to be displaced, thereby facilitating the maintenance of the stability of the tensioning force. In addition, it can be understood that the crimping roller 322 at the highest position on the crimping frame 321 can be used as a reversing roller, so that the cloth on the driven roller 2 can bypass the reversing roller and be wound around the active roller 1, thereby reducing the contact between the cloth and the crimping frame 321 or the receiving frame 311, so as to reduce the wear on the cloth.

Referring to Figures 2 and 3, a pair of upper limit retaining rings 323 are provided on each crimping roller 322 to stop the driven roller 2 between the pair of upper limit retaining rings 323 that are relatively arranged, so as to ensure that the driven roller 2 and the cloth on the driven roller 2 are not prone to shaking along the feeding direction perpendicular to the cloth on the receiving part 31, so as to make the unwinding more stable.

The working principle of the unwinding machine of this application is as follows:

The active roller 1 is driven to rotate by the unwinding motor 4 to realize the unwinding of the cloth on the driven roller 2. The driven roller 2 is crimped between the receiving portion 31 and the crimping portion 32 so as to realize positioning. The driven roller 2 can rotate between the receiving portion 31 and the crimping portion 32, and can also provide tensioning force for the cloth during the unwinding process through the friction between the cloth on the driven roller 2 and the crimping portion 32 as well as the receiving portion 31, so there is no need to set a motor to drive the driven roller 2 to rotate, which can save costs. In addition, the friction between the cloth on the driven roller 2 and the crimping portion 32 as well as the receiving portion 31 can be adjusted by inserting counterweight blocks 6 of different weights into the slide groove 331, so that the tensioning force of the cloth during the unwinding process can be adjusted.
