Description

Technical Field

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

[0002] Transferring gold and silver cardboard is a printing process that is widely used in color printing packaging. It is an emerging anti-counterfeiting technology in the industry. During the production process of gold and silver cardboard, the raw material is white cardboard of the same specifications. After the cardboard is colored, it will be rewound for transportation. To prevent discoloration, a protective film will be attached to the surface of the cardboard. The protective film needs to be removed before the cardboard leaves the factory so that it can be used directly by customers, which requires the use of a cardboard protective film peeling and rewinding device.

[0003] According to the Chinese patent with the authorized publication number CN217894665U, a coated paper film stripping and rewinding device is disclosed. When stripping the film, the protective film is passed through the gap between the pressure roller and the arc-shaped groove, and is transmitted forward around the steering roller. The pressure roller presses the coated paper, thereby reducing the tension on the coated paper when stripping the film, and effectively avoiding the coated paper from tearing when stripping the film. In actual use, the gap between the pressure roller and the arc-shaped groove is fixed, while the thickness of the coated paper board or cardboard is generally different, so the gap between the pressure roller and the arc-shaped groove cannot be effectively adjusted according to the actual situation, which may result in the expected effect of reducing the tension when stripping the film, and may cause the coated paper board or cardboard to tear when stripping the film, reducing the practicality of the existing film stripping and rewinding device.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figure 1-3The utility model provides a technical solution: a cardboard protective film peeling and rewinding device, comprising a bottom plate 1, a feeding assembly 200 installed on the top of the bottom plate 1 for placing raw materials, a peeling structure 300 installed on the top of the bottom plate 1 for peeling the cardboard, and a rewinding assembly 400 installed on the top of the bottom plate 1 for rewinding the cardboard and the protective film;

[0030] Through the coordinated use of the bottom plate 1, the feeding assembly 200, the film peeling structure 300 and the rewinding assembly 400, the gap between the pressure rollers can be effectively adjusted according to the actual thickness of the copper paperboard or the transfer gold and silver cardboard, thereby ensuring that the expected effect of reducing the tension when peeling the film can be achieved, avoiding the copper paperboard or the transfer gold and silver cardboard from tearing when peeling the film, thereby more efficiently completing the separation of the cardboard and the protective film. At the same time, the cardboard and the protective film after peeling the film can be rewound synchronously to ensure tight rewinding, facilitate subsequent packaging and transportation, and improve the practicability of the film peeling and rewinding equipment.

[0031] In this embodiment, the feeding component 200 is a structure for feeding.

[0032] like Figure 1 As shown, the feeding assembly 200 includes a fixed platform 201 fixed to the top of the bottom plate 1 , a support frame 202 fixed to the top of the fixed platform 201 , and a raw material roller 203 rotatably connected to the top of the support frame 202 .

[0033] In this embodiment, the film peeling structure 300 is a structure for peeling off the film of cardboard.

[0034] like Figure 1 and Figure 2 As shown, the film peeling structure 300 includes two vertical plates 301 fixed on the top of the bottom plate 1, an adjustment component 302 installed inside the vertical plates 301 for adjusting the pressure roller, and a squeezing component 303 installed between the two vertical plates 301 for squeezing the cardboard.

[0035] In this embodiment, the adjustment component 302 is a structure that can be effectively adjusted according to actual conditions.

[0036] like Figure 1 and Figure 2 As shown, the adjustment assembly 302 includes a hydraulic rod 3021 fixed inside the vertical plate 301 and an adjustment block 3022 fixed at the bottom end of the hydraulic rod 3021 .

[0037] It should be noted that an adjustment groove 3023 is provided on one side opposite to the two vertical plates 301 , and the top of the hydraulic rod 3021 is fixed to the inner top wall of the adjustment groove 3023 , so that the hydraulic rod 3021 is effectively fixed.

[0038] In this embodiment, the squeezing assembly 303 is a structure for effectively squeezing the jammed paper.

[0039] like Figure 1 and Figure 2 As shown, the extrusion assembly 303 includes a first pressing roller 3031 rotatably connected between opposite sides of two adjustment blocks 3022 through a bearing, and a second pressing roller 3032 rotatably connected between opposite sides of two vertical plates 301 through a bearing.

[0040] It should be noted that the adjustment block 3022 is slidably connected in the adjustment groove 3023, so that the adjustment block 3022 can slide more stably in the adjustment groove 3023. The diameter of the adjustment block 3022 is smaller than the outer diameter of the first pressure roller 3031, ensuring that the first pressure roller 3031 and the second pressure roller 3032 can effectively press the jammed paper.

[0041] In this embodiment, the rewinding assembly 400 is a structure that can effectively rewind the cardboard and the protective film respectively.

[0042] like Figure 1 and Figure 3 As shown, the rewinding assembly 400 includes two fixed plates 401 fixed to the top of the base plate 1, two first docking ends 402 rotatably connected to the opposite sides of the two fixed plates 401, two second docking ends 403 rotatably connected to the opposite sides of the two fixed plates 401, a motor 404 fixed to the back side of the back fixed plate 401, a connecting column 405 fixed to the output shaft of the motor 404, three pulleys 406 respectively fixed to the outer sides of the first docking ends 402 on the front and back sides of the connecting column 405 and the outer sides of the second docking ends 403 on the back sides, and a belt 407 slidably connected between the outer sides of the three pulleys 406.

[0043] It should be noted that the front side of the connecting column 405 passes through the back fixing plate 401 and extends to the front side of the back fixing plate 401 to be fixed to the right side pulley 406, ensuring that the motor 404 can drive the right side pulley 406 to rotate through the connecting column 405. A support plate is fixed to the bottom of the motor 404 to effectively fix the motor 404.

[0044] In addition, the belt 407 and the pulley 406 are preferably of a toothed meshing type.

[0045] The working principle of the above embodiment is:

[0046] When in use, the raw material roller 203 to be peeled off is placed on the support frame 202, and then the cardboard to be peeled off passes through the middle of the first pressure roller 3031 and the second pressure roller 3032, and at the same time, the hydraulic rod 3021 is opened to drive the adjustment block 3022 to move up and down in the adjustment slot 3023, thereby driving the first pressure roller 3031 to move up and down, thereby adjusting the gap between the first pressure roller 3031 and the second pressure roller 3032, ensuring that the normal operation of the film peeling process is not affected during the film peeling process. The two pressure rollers 3032 press the jammed paper, thereby reducing the tension on the jammed paper when peeling off the film, effectively avoiding the jammed paper from tearing, and then installing rollers in the two first docking ends 402 and the two second docking ends 403 respectively, and then winding the jammed paper and the protective film around the two rollers respectively, and then turning on the motor 404 to drive the pulley 406 and the belt 407 to rotate, so that the jammed paper and the protective film are rewound by the two rollers. After the rewinding is completed, the front fixing plate 401 can be removed by loosening the bolts, so as to facilitate the removal of the rollers after the rewinding is completed.

[0047] Compared with the prior art, the cardboard protective film peeling and rewinding device, through the coordinated use of the bottom plate 1, the feeding assembly 200, the film peeling structure 300 and the rewinding assembly 400, can effectively adjust the gap between the pressure rollers according to the actual thickness of the copper paperboard or the transfer gold and silver cardboard, thereby ensuring that the expected effect of reducing the tension when peeling the film can be achieved, avoiding the copper paperboard or the transfer gold and silver cardboard from tearing when peeling the film, thereby more efficiently completing the separation of the cardboard and the protective film, and at the same time, the cardboard and the protective film after peeling the film can be synchronously rewound to ensure tight rewinding, facilitate subsequent packaging and transportation, improve the practicability of the film peeling and rewinding equipment, and solve the problem of low practicability of the existing film peeling and rewinding equipment.

[0048] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
