Embodiment Construction

[0013] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 and 2 As shown, a pressure-adjustable heat-shrinkable film winding roll includes a roll body 1, a piercing plate 3, and a pressure-resisting mechanism 2; the inside of the roll body 1 is provided with a cavity; the roll body 1 A through groove 11 is respectively provided on both sides of the middle; the through groove 11 communicates with the cavity inside the roller body 1; the penetration plate 3 is fixed on one end surface of the roller body 1; the penetration plate 3 is provided with a threaded through hole; the pressing mechanism 2 includes two adjustment blocks 21, two connecting elastic bodies 24, two pressing plates 22, two connecting columns 23, two limit frames 26, a driving Screw 25; the two adjustment blocks 21 are arranged parallelly up and down inside the cavity of the roller body 1; a limiting frame 26 i...

Abstract

The invention provides an abutting-pressing adjusting wind-up roller for a hot shrink film. The abutting-pressing adjusting wind-up roller for the hot shrink film comprises a roller body, a piercing plate and an abutting-pressing mechanism. The piercing plate is fixed on one end face of the roller body. A threaded through-hole is formed in the piercing plate. The abutting-pressing mechanism comprises two adjusting blocks, two connecting elastomers, two abutting-pressing plates, two connecting columns, two limit frames and a driving screw. The structure design of the abutting-pressing adjustingwind-up roller for the hot shrink film is ingenious. The abutting-pressing mechanism is set inside the roller body. By rotating the driving screw, a conical driving head of the driving screw is constantly moved into the space between the two adjusting blocks. Thus, the adjusting blocks are pushed to move outwards along the limit frames, the adjusting blocks extrude the connecting elastomers and the connecting elastomers elastically extrude the abutting-pressing plates outward, so that the abutting-pressing plates abut against and are pressed on the inner side of the hot shrink film, the hot shrink film is more stably rolled on the roller body and the occurrence of slipping is avoided.

Description

technical field [0001] The invention relates to a pressure-adjustable heat-shrinkable film winding roller. Background technique [0002] With the development of society, heat-shrinkable film packaging bags are used more and more widely, especially in the application of commodity packaging. The existing heat-shrinkable film is generally wound on the winding roller, and the existing winding roller It is a cylindrical structure with an integral structure, but the existing structure of the winding roller, the heat shrinkable film is easy to slip on the winding roller, making the connection of the heat shrinkable film on the winding roller unstable. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a pressure-adjustable heat-shrinkable film take-up roller with adjustable tension, anti-skid, and stable connection. [0004] In order to solve the above problems, the tech...
