Description

Technical Field

[0001] The utility model relates to the field of wrapping machines, in particular to a pressure wheel device for wrapping machines. Background Art

[0002] Wrapping machines (wrapping machines) are widely used in the containerization of products such as foreign trade exports, food and beverages, plastic chemicals, glass and ceramics, and electromechanical castings. They can prevent damage to goods during transportation and play a role in dust, moisture and cleaning.

[0003] The press wheel device for a three-dimensional transparent wrapping machine described in announcement number CN216402041U drives the slider to move in the slide groove through the multi-stage hydraulic cylinder arranged in the adjustment component, so that it drives the rotating motor and the press wheel body to move up and down, which is convenient for adjusting the distance between the press groove and the up and down movement. It is suitable for material thickness within a certain range. The telescopic rod is formed by the first sleeve, the second sleeve and the third sleeve arranged in the applicable component, so that it can be telescopically lengthened. The second fixed plate cooperates with the threaded block to fix the press wheel bodies of different sizes, which is convenient for replacing the press wheels of different sizes and improving the applicability. However, the prior art still has defects:

[0004] 1. In the prior art, the article is placed in a pressing groove and the pressing wheel body is pressed down and rotated to drive the article to rotate for wrapping and winding. Although a smooth layer is set in the pressing groove, there is still a large friction due to the irregularity of the article itself and the different smoothness of the surface of the wrapping film. This makes it difficult to effectively drive the article to be wrapped and wound close to the pressing wheel body, and the practicality is insufficient.

[0005] 2. In the prior art, only one side of the pressure wheel body is connected to the slider through a rotating motor, and the applicable component is a telescopic structure. When the applicable component is extended, as the motor rotates, the pressure wheel body is difficult to maintain stability, and the fixed support capacity is poor. After external force is applied, the pressure wheel body is prone to deflection and displacement. Utility Model Content
