Description

Technical Field

[0001] The utility model belongs to the technical field of cloth production equipment, and in particular relates to a cloth tensioning and adjusting device. Background Art

[0002] Fabric is a common material used in decoration. It includes various types of fabrics, including chemical fiber carpets, non-woven wall coverings, linen, nylon, colored tape, flannel, and more. During the production process, fabrics need to be pulled through the production equipment.

[0003] Because the fabric production equipment is affected by friction and other resistance during the fabric pulling process, the fabric's own tension is too low or too high. When the fabric is too tight, it is easy to tear, and when it is too loose, it is easy to get stuck, making it difficult for conventional fabric production equipment to automatically adjust the tension.

[0004] To this end, we propose a fabric tensioning and adjusting device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that conventional cloth production equipment is difficult to automatically adjust the tension, and proposes a cloth tensioning adjustment device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A cloth tensioning and adjusting device comprises a first bearing seat, the outside of the first bearing seat is fixedly connected to a frame, a sliding column is slidably installed inside the first bearing seat, two sliding columns are rotationally symmetrically distributed, a first induction switch and a second induction switch are fixedly connected to the frame, the first induction switch and the second induction switch are arranged on the upper and lower sides of one of the sliding columns, a tension spring is sleeved on the sliding column, one end of the tension spring is fixedly connected to the sliding column, and the other end of the tension spring is fixedly connected to the first bearing seat, and a rotating drum is rotatably installed on the first bearing seat and the sliding column, wherein two rotating drums are distributed on the first bearing seat. The fabric is put on the drum for traction, and the elastic force of the tension spring is used to act on the slide column, so that the slide column acts on the drum, and acts on the fabric through the drum. When the fabric is too tight, the elastic force of the tension spring is overcome to cause the slide column to contract. Conversely, the elastic force of the tension spring is used to compensate for the tensioning force of the fabric. When the slide column triggers the second induction switch, an electrical signal to increase the traction speed is sent. When the slide column triggers the first induction switch, an electrical signal to decelerate the traction is sent, so that the tensioning force of the fabric is balanced within a smaller range, which is convenient for automatic adjustment of the tensioning force.

[0008] Preferably, the frame includes a fixing column and a mounting seat, and the lower end of the fixing column is fixedly connected to the side end of the mounting seat.

[0009] Preferably, the upper end of the mounting base is hollowed out to form a mounting hole, through which an external screw is passed to be installed on the ground, so that the rack can be fixed with the external screw.

[0010] Preferably, the frame further comprises a reinforcing rod fixedly connected between the fixing column and the mounting seat, so as to increase the stability of the angle between the fixing column and the mounting seat and improve the firmness of the frame structure.

[0011] Preferably, the sliding column includes a stop block, a column, and a second bearing seat, wherein the stop block is fixedly connected to the upper end of the column, and the second bearing seat is fixedly connected to the lower end of the column. The elastic force of the tension spring acts on the stop block, which in turn acts on the column, which in turn acts on the second bearing seat, thereby facilitating the second bearing seat to apply the elastic force of the tension spring to the rotating drum.

[0012] Preferably, the drum includes a drum body and a rotating shaft, wherein the rotating shaft is fixedly connected to the side end of the drum body. When the cloth moves, the cloth drives the drum body to rotate, and the drum body drives the rotating shaft to rotate along the second bearing seat, thereby reducing the resistance to cloth movement.

[0013] Preferably, the rotating drum further comprises a guide block fixedly connected to one end of the drum body facing away from the rotating shaft. When the fabric is sleeved, the guide block is used to guide the fabric to sleeve onto the drum body, thereby reducing the difficulty of assembling the fabric.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Put the fabric on the drum for traction, and use the elastic force of the tension spring to act on the slide column, so that the slide column acts on the drum, and then acts on the fabric through the drum. When the fabric is too tight, the elastic force of the tension spring is overcome to cause the slide column to contract. Conversely, the elastic force of the tension spring is used to compensate for the tensioning force of the fabric. When the slide column triggers the second induction switch, an electrical signal to increase the traction speed is sent. When the slide column triggers the first induction switch, an electrical signal to slow down the traction is sent, so that the tensioning force of the fabric is balanced within a smaller range, which is convenient for automatic adjustment of the tensioning force.

[0016] 2. The elastic force of the tension spring acts on the limit block, the limit block acts on the column, and the column acts on the second bearing seat, making it convenient for the second bearing seat to apply the elastic force of the tension spring to the rotating drum.

[0017] 3. When the fabric moves, the fabric drives the cylinder to rotate, and the cylinder drives the rotating shaft to rotate along the second bearing seat, thereby reducing the resistance to fabric movement. BRIEF DESCRIPTION OF THE DRAWINGS
