Description

Technical Field

[0001] The utility model belongs to the technical field of PE film processing, in particular to an automatic regulating device for controlling the tension of a PE film. Background Art

[0002] PE protective film is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. PE protective film uses special polyethylene (PE) plastic film as its base material. During the processing of PE protective film, a tension control system is required to realize automatic adjustment of tension control.

[0003] The current PE film tension control automatic adjustment device lacks a positioning structure for the film body, and the film body is likely to deviate during processing, which reduces the quality of the finished product.

[0004] For example, a Chinese patent document (publication number CN116462034A) in the prior art discloses an automatic adjustment device for controlling the tension of a PE film. The device has a simple structure and strong practicality. It can automatically adjust the distance between the first traction wheel and the second traction wheel according to the thickness of the PE film without manual adjustment, thereby improving the accuracy of the device. However, the prior art has the following problems: there is a lack of a positioning structure for the film body, and the film body is likely to deviate during processing, which reduces the quality of the finished product.

[0005] Therefore, in view of this situation, it is urgent to design and produce a PE film tension control automatic adjustment device to meet the needs of practical use. Utility Model Content

[0006] The utility model aims to provide a PE film tension control automatic adjustment device to solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PE film tension control automatic adjustment device, comprising a support block used for PE film tension control automatic adjustment, the inner side of the support block is rollingly connected to a first connecting plate, the end of the first connecting plate away from the support block is fixedly connected to a first rotating shaft, the side of the support block is sleeved with a sliding wheel, the side of the sliding wheel is fixedly connected to a pushing rod sleeved with the support block, the side of the sliding wheel is slidably connected to a movable plate, and the side of the first rotating shaft is rotatably connected to a first fixed plate.

[0008] Preferably, a first motor for providing power for automatic adjustment of the PE film tension control is installed on the side of the first fixed plate, and a second fixed plate is fixedly connected to the upper side of the first fixed plate.

[0009] Preferably, a sliding rod sleeved with the movable plate is fixedly connected to the side of the second fixed plate, and a second motor is installed on the side of the second fixed plate.

[0010] Preferably, the output end of the second motor is fixedly connected with a threaded rod, and the side of the first fixed plate is fixedly connected with a fixed frame for automatic adjustment of the PE film tension control.

[0011] Preferably, a telescopic rod is fixedly connected to the lower side of the fixed frame, and the extended end of the telescopic rod is fixedly connected to the movable frame.

[0012] Preferably, a rolling shaft is rotatably connected to the inner side of the movable frame, and a first limiting rod is sleeved on the side of the movable frame.

[0013] Preferably, a limit plate is sleeved on the side of the rolling shaft, a second limit rod sleeved with the movable plate is fixedly connected to the upper side of the limit plate, and a base is fixedly connected to the lower side of the first fixed plate.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The PE film tension control automatic adjustment device drives the threaded rod to rotate through the second motor, and the rotation of the threaded rod drives the movable plate to move, drives the sliding wheel and the limiting plate to move, thereby limiting the PE film. The push rod and the support block are engaged with each other, which can prevent the PE film from escaping from the limiting range of the movable plate. When the first motor drives the first rotating shaft and the support block to rotate, the push rod and the sliding wheel can be driven to rotate, thereby reducing the power source and reducing the consumption of finished products.

[0016] The PE film tension control automatic adjustment device drives the mobile frame to move through the telescopic rod, which can drive the PE film to stretch and realize the control of the PE film tension. It is said that during the movement, the first limit rod can limit the mobile frame. At the same time, when the mobile frame moves up and down, the second limit rod can move up and down synchronously to avoid affecting the movement of the limit plate, thereby realizing the limitation of the PE film.
