Description

Technical Field

[0001] The present application relates to the technical field of protective film rewinding, and in particular to a cardboard protective film peeling and rewinding device. Background Art

[0002] In the current packaging and printing industry, cardboard is a common material widely used in the production of various product packaging, brochures, business cards, etc. However, with the intensification of market competition and the continuous improvement of consumer demand, the requirements for the surface protection and processing efficiency of cardboard are becoming increasingly stringent.

[0003] In the production and processing of cardboard, the application of protective film is particularly important. The protective film can not only protect the cardboard surface from scratches, pollution and other damage, but also provide stable support and protection during subsequent processing.

[0004] Before the cardboard leaves the factory, the protective film needs to be removed so that the customer can use it directly. The traditional method of removing the protective film is usually to use a rewinding device to wind the protective film on a roller, and at the same time complete the separation of paper and film during operation, so that the cardboard is wound on another roller alone. However, this method of rewinding the used protective film makes it easy for creases, wear and tear to appear on the surface of the protective film. These marks not only affect the appearance quality of the protective film, but also reduce its performance and life of secondary use. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the way of rewinding the used protective film makes it easy for creases, wear and tear to appear on the surface of the protective film, which not only affects the appearance quality of the protective film, but also reduces its performance and life of secondary use. The present application provides a cardboard protective film peeling and rewinding device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A cardboard protective film peeling and rewinding device comprises a U-shaped base, one end of the U-shaped base is rotatably connected to a feeding roller, and the other end of the U-shaped base is rotatably connected to a winding roller, one end of the U-shaped base is fixedly connected to a winding motor, the output end of the winding motor is fixedly connected to the winding roller, the interior of the U-shaped base is rotatably connected to a traction roller, the interior of the U-shaped base is fixedly connected to a heating lamp, the heating lamp is installed between the feeding roller and the traction roller, a reciprocating slide groove is provided at one end of the U-shaped base, a reciprocating slider is slidably connected to the interior of the reciprocating slide groove, one end of the reciprocating slider is fixedly connected to a knocking rod, and a driving component for driving the reciprocating slider to reciprocate along the length direction of the reciprocating slide groove is installed inside the reciprocating slide groove.

[0020] By adopting the above technical solution, through the combined use of the adjustment component and the adjustment roller, it is convenient to use the adjustment component to push the adjustment roller to drive one end of the protective film to move downward along the length direction of the adjustment chute, thereby stretching the protective film, so as to facilitate maintaining the tension of the protective film and effectively improving the practicability of the device.

[0021] Further, the adjustment component includes an adjustment slide rod fixedly connected to one side of the U-shaped base, an adjustment spring is sleeved at one end of the adjustment slide rod, one end of the adjustment spring is fixedly connected to the top end of the adjustment slider, and one end of the adjustment slider is slidably connected to the adjustment slide rod.

[0022] By adopting the above technical solution, through the combined use of the adjustment slide rod and the adjustment spring, it is convenient to utilize the resilience characteristic of the adjustment spring to make the adjustment spring push the adjustment slider downward along the length direction of the adjustment slide rod, and then make the adjustment slider drive the adjustment roller to move downward along the length direction of the adjustment chute, improving the practicability of the device.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By the combined use of the driving component and the heating lamp, it is convenient to start the heating lamp and the driving component, so that after the heating lamp heats the protective film passing between the loading roller and the traction roller, the driving reciprocating slider drives the knocking rod to continuously reciprocate along the length direction of the reciprocating chute, and then makes the knocking rod vibrate and knock the protective film heated and bypassing one end of the traction roller, so that the crease part on the surface of the protective film is evenly spread out, thereby reducing the creases and other imprints on the surface of the protective film and prolonging the service life of the protective film.
