Description

Technical Field

[0001] This utility model relates to the technical field of cloth tape production equipment, and in particular to a tension balancing device for pulling cloth tape. Background Technology

[0002] In the production of cloth-based adhesive tape, the stretching process is one of the key steps. Its purpose is to smoothly transport the semi-finished or finished cloth-based adhesive tape to subsequent processing stations, such as slitting and winding, at a set speed. However, existing stretching equipment often experiences unstable tension on the cloth-based adhesive tape during the stretching process due to factors such as fluctuations in stretching speed, uneven thickness of the tape itself, and wear of guide components. Excessive tension can cause problems such as tensile deformation and substrate breakage in cloth-based adhesive tapes, affecting product dimensional accuracy and mechanical properties. Conversely, insufficient tension can lead to slackness and wrinkles in the tape, disrupting subsequent processing steps and reducing production efficiency and product yield. Currently, the industry primarily uses manual periodic adjustment of tension rollers to control tension. This method is not only slow and inaccurate but also unable to adapt to dynamic changes during the pulling process, making it difficult to achieve continuous tension balance and meet the demands of modern continuous production. Therefore, we propose a tension balancing device for cloth-based adhesive tape pulling. Utility Model Content

The two ends of the frame 1 are respectively provided with shaft holes. The two ends of the positioning roller 24 are respectively installed with shaft holes. The two ends of the positioning roller 24 are rotatably connected with shaft holes. The outer rings of the adjusting roller 23 and the positioning roller 24 are both covered with rubber anti-slip sleeves, so that the cloth tape can be more stable during the pulling operation. The setting of the adjusting push rod 21 can drive the adjusting roller 23 to be adjusted up and down through the adjusting block 22, so that the specific distance between the adjusting roller 23 and the positioning roller 24 can be adjusted, thereby enabling the device to adapt to the pulling operation of cloth tape of different thicknesses. The two sets of frame 1 at both ends of the frame 1 can be selected for use according to the needs of the operation. A tension detection assembly 3 is installed at the middle position on the frame 1. The tension detection assembly 3 includes adjusting cylinders 31 located on both sides of the frame 1. Assembly slots are opened at the middle position on both sides of the frame 1.

The connection is as follows: the stabilizing plate 55 is slidably connected to the guide rod 54, and one end of the bidirectional threaded rod 53 is fixedly connected to the output end of the drive motor 51. The bidirectional threaded rod 53 can drive the two sets of stabilizing plates 55 to move synchronously along the guide rod 54. The stabilizing limit component 5 can be adapted to the stable pulling operation of cloth tape of different widths. The stabilizing limit component 5 and the feeding and discharging component 2 cooperate with each other to limit the movement of the cloth tape when it is in a pulling state, ensuring the stability and balance of the cloth tape pulling. A PLC controller 6 is installed on one side of the frame 1. The mounting end of the PLC controller 6 is installed corresponding to one side of the frame 1 and is fixedly connected to one side of the frame 1.

The PLC controller 6 allows the equipment to pull cloth tape without frequent manual intervention, reducing the labor intensity of the operator. At the same time, the preset tension threshold can be flexibly adjusted through the PLC controller 6 to adapt to the pulling needs of cloth tape of different specifications, materials and thicknesses, making it highly versatile.

[0016] In this embodiment, the operator sets the specifications and dimensions of the fabric tape to be pulled using the PLC controller 6. Then, the operator positions one end of the fabric tape relative to a set of infeed / outfeed components 2. The PLC controller 6 controls the adjusting push rod 21, causing it to move up and down via the adjusting block 22, adjusting the adjusting roller 23 to match the distance between the adjusting roller 23 and the positioning roller 24 with the fabric tape. The drive motor 51 then drives the stabilizing plate 55 along the guide rod 54 via the bidirectional threaded rod 53, bringing the two sets of stabilizing plates 55 closer together to one side of the fabric tape. Finally, one end of the fabric tape passes under a set of path rollers 4 located below, allowing the fabric tape to... One end of the belt passes above the outer side of the upper set of path rollers 4 and below the outer side of the tension roller 33. Then, it continues to drive one end of the cloth belt to pass above the outer ring of the upper set of path rollers 4 and below the outer ring of the lower set of path rollers 4 on the other side of the tension detection component 3. Finally, the top of the cloth belt passes between the adjusting roller 23 and the positioning roller 24 on another set of feed and discharge components 2, thus completing the overall tension path layout of the cloth belt. When the cloth belt is in the tension operation, the tension force of the cloth belt will be converted into radial pressure on the tension roller 33. The tension sensor 34 monitors the pressure of the cloth belt on the tension roller 33 in real time and sends the pressure signal to the PLC controller 6 for conversion to obtain the actual tension force of the cloth belt.
