Description

Technical Field

[0001] The utility model belongs to the technical field of textile processing, in particular to a tension control and adjustment device for a rolling machine. Background Art

[0002] Textiles, that is, products processed by textiles, include yarns, woven fabrics, knitted fabrics, braided fabrics, etc., which are divided into two categories: woven fabrics and knitted fabrics. After the fabric processing is completed, the fabric needs to be rolled up, that is, the processed fabric is rolled up onto the fabric winding roller to facilitate the transportation of the fabric between various processes and its final preservation. During the fabric winding process, a tension adjustment mechanism is usually equipped to adjust the tension of the fabric during winding, so as to avoid curling of the fabric due to excessive tension during winding.

[0003] In the prior art, the tension of the fabric is mostly adjusted by adjusting the torque of the winding roller motor. The tension adjustment effect is poor, and the fabric is easily distorted and offset during the adjustment process. The existing equipment does not have a limiting structure, which is inconvenient to use.

[0004] In view of the above problems, the utility model document proposes a tension control and adjustment device for a rolling machine. Utility Model Content

[0005] The purpose of the utility model is to provide a tension control and adjustment device for a rolling machine, which can tightly adsorb the cloth on the surface of the adjustment roller through the negative pressure generated by the exhaust fan, effectively prevent the cloth from slipping during the transmission process, improve the stability and reliability of the device, and solve the existing technical problems.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] A tension control and adjustment device for a rolling machine, comprising:

[0008] A bottom plate, wherein four first fixing frames are fixed on the top of the bottom plate, and two positioning rollers are rotated between the four first fixing frames;

[0009] A U-shaped frame is provided on the upper side of the bottom plate, an adjusting roller rotates inside the U-shaped frame, the cloth is arranged on the lower side of two positioning rollers, the adjusting roller is arranged on the lower side of the cloth, and a group of adjusting components are provided between the bottom plate and the U-shaped frame, and the adjusting components are used to quickly adjust the tension of the cloth;

[0010] A tension sensor, wherein two second fixing frames are fixed on the top of the bottom plate, and the tension sensor is arranged in the two second fixing frames for detecting the tension of the cloth;

[0011] Two sets of limiting components, the two sets of limiting components are respectively arranged in two positioning rollers for limiting the movement of the cloth;

[0012] The laminating component is arranged in the adjusting roller and is used for adsorbing the cloth on the surface of the adjusting roller.

[0013] Optionally, the adjustment component includes a first groove opened in the base plate, a limiting slide sliding in the first groove, the U-shaped frame is fixed to the top of the limiting slide, two threaded blocks also slide in the first groove, a first bidirectional screw rod rotates in the first groove, the two threaded blocks are respectively threadedly connected to the positive and negative thread segments on the circumferential surface of the first bidirectional screw rod, the top ends of the two threaded blocks are rotated with support rods through hinges, the side ends of the two support rods are rotated to the bottom end of the limiting slide rod through hinges, a driving motor is fixed to the side end of the base plate, the driving motor is fixedly connected to the first bidirectional screw rod through a coupling, and the driving motor is electrically connected to the tension sensor.

[0014] Optionally, each group of the limiting components includes a second groove opened in the positioning roller, two threaded rings slide in the second groove, a second bidirectional screw rod rotates in the second groove, the two threaded rings are respectively threadedly connected to the positive and negative thread segments on the circumferential surface of the second bidirectional screw rod, limiting rings are fixed on the surfaces of the two threaded rings, and the two limiting rings slide on the surface of the positioning roller.

[0015] Optionally, the surfaces of the two positioning rollers are provided with scales for observing the distance between the two limiting rings.

[0017] Optionally, the air inlet pipe is rotated to connect to the side end of the connecting pipe.

[0018] In the present application, according to the length of the fabric, the twisting ring is twisted to drive the second bidirectional screw to rotate, and the rotation of the second bidirectional screw drives the two threaded rings to move in a direction close to or away from each other to adjust the distance between the two threaded rings and the two limiting rings. The two limiting rings will limit the fabric so that it will not deviate;

[0019] The cloth is moved by rotating the winding roller. When the cloth passes through the tension sensor, the tension sensor detects the cloth tension. The tension sensor drives the first bidirectional lead screw to rotate by starting the drive motor. The rotation of the first bidirectional lead screw drives the two threaded blocks to move in directions away from each other. The movement of the threaded blocks in directions away from each other drives one end of the two support rods. The two support rods drive the limiting slide plate and the U-shaped frame to move upward. The U-shaped frame drives the adjusting roller to move upward. The adjusting roller moves to tighten the cloth, so that the tension of the cloth increases, and vice versa. The tension of the cloth decreases.

[0020] In the utility model, the tension control and adjustment device of the roll forming machine can achieve the effect of quickly and effectively adjusting the tension of the cloth by adjusting the components;

[0021] In the utility model, the tension control and adjustment device of the rolling machine can achieve effective effects through the laminating component and the limiting component;

[0022] In this technical solution, combined with the real-time detection and feedback control of the tension sensor, the tension of the cloth can be accurately controlled to avoid loosening or tightening of the cloth during the transmission and winding process. The negative pressure generated by the exhaust fan in the bonding component tightly adsorbs the cloth to the surface of the adjusting roller, effectively preventing the cloth from slipping during the transmission process and improving the stability and reliability of the device.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
