Description

Technical Field

[0001] The utility model relates to the technical field of protective film composites, in particular to a protective film composite device for electron beam curing. Background Art

[0002] The protective film is used to attach to the surface of the object and wrap the surface of the object to prevent the surface of the object from being scratched and damaged. During the protective film forming process, multiple layers of single films need to be composited through a composite device. Since the single film composite processing needs to be bonded with materials such as glue, it is processed by electron beam curing. When irradiated by the electron beam, the coating polymer is cross-linked and cured, thereby improving the composite efficiency.

[0003] Since the protective film needs to be transported during the lamination process, the edge of the film is prone to bend and warp during the transportation process, which will cause the edge of the film after lamination to be folded, thereby affecting the molding quality of the protective film;

[0004] The existing patent (announcement number: CN210257267U) discloses an anti-warping protective film composite device. During the composite process of the protective film body, the protective film body is facilitated to slide stably horizontally by the limit frame provided on the top surface of the support plate. Then, the protective film body is stably squeezed by the lower pressure cylinder and the roller to reduce the warping at the edge of the protective film body.

[0005] In response to the above problems, although the solution provided by the existing patent can avoid warping by pressurizing the lower pressure cylinder and the roller, the clamping of the lower pressure cylinder and the roller during the winding and conveying of the protective film may slow down the conveying speed of the protective film, which may cause loosening or pulling, resulting in wrinkles in the protective film, affecting the quality and appearance of the protective film. Summary of the invention

[0006] The purpose of the utility model is to provide a protective film composite device for electron beam curing, which can avoid wrinkles caused by loosening or tensioning and affect the quality of the composite, so as to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective film composite device for electron beam curing, comprising a processing box, wherein both ends of the outer wall of the processing box are provided with inlets and outlets, and a curing device body is embedded at the center of the top of the processing box, a mounting shell is fixed on one side of the top of the processing box, and a tensioning mechanism is arranged inside the mounting shell;

[0008] The tensioning mechanism includes a motor, which is embedded in one side of the outer wall of the mounting shell, and a worm is connected to the power output end of the motor. The worm passes through the outer wall of the mounting shell and is connected to a worm wheel, and a threaded rod passes through the inside of the worm wheel. A positioning groove is opened on the inner wall of the processing box corresponding to the position of the threaded limit rod, a winding sleeve is slidably connected to one side of the limiting groove, and a rubber pad is provided on the outer wall of the winding sleeve.

[0009] Preferably, the winding sleeve is threadedly connected to the threaded rod, and the winding sleeve forms a sliding structure with the processing box through the limiting groove.

[0010] Preferably, a glass plate is embedded in the front end of the processing box, and slide plates are slidably connected to both sides of the curing device body at the top of the processing box.

[0011] Preferably, a carrying platform is fixed on one side of the inlet and outlet at both ends of the inner wall of the processing box, and a pressing mechanism is provided on the other side of the carrying platform.

[0012] Preferably, the pressing mechanism comprises a connecting rod, the connecting rod is fixed at two ends of the winding sleeve, and a lower pressing plate is installed between the two connecting rods.

[0013] Preferably, the pressing mechanism further comprises a damping spring, which is embedded in the bottom end of the lower pressing plate, and one end of the damping spring is connected to a connecting shell, and two axial directions of the connecting shell are rotatably connected to rollers relative to the outer wall.

[0014] Preferably, the structure of the connecting shell is a U-shaped structure, and the connecting shell forms an elastic structure with the lower pressure plate through a damping spring.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The treatment box is used to avoid pollution caused by external dust adsorption during the composite process. The curing equipment body uses electron beam curing to improve the solidification efficiency of the glue during the conveying process, thereby improving the composite efficiency. The motor works to drive the worm and worm gear, so that the two threaded rods drive the corresponding winding sleeve to slide, thereby tensioning and adjusting the protective film to avoid loosening or tightening to cause wrinkles, which affects the quality of the composite.

[0017] 2. Driven by the winding sleeve, the connecting rod and the lower pressure plate move toward the bearing platform, so that the roller slides against the protective film. The damping spring elastically expands and contracts, and excessive compression makes it difficult to transport. At the same time, it plays a certain compression limit to avoid warping and wrinkles during the conveying process. At the same time, the roller improves the smoothness of the conveying process.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 3A protective film composite device for electron beam curing includes a processing box 1, and an inlet and outlet 2 are opened at both ends of the outer wall of the processing box 1. A curing device body 3 is embedded at the center of the top of the processing box 1. A mounting shell 4 is fixed to one side of the top of the processing box 1, and a tensioning mechanism 5 is arranged inside the mounting shell 4; the tensioning mechanism 5 includes a motor 501, the motor 501 is embedded on one side of the outer wall of the mounting shell 4, a worm 502 is connected to the power output end of the motor 501, the worm 502 penetrates the outer wall of the mounting shell 4 and is connected to a worm wheel 503, and the worm wheel A threaded rod 504 extends from the inside of 503, and a limiting groove 507 is provided on the inner wall of the processing box 1 at a position corresponding to the threaded rod 504. A winding sleeve 505 is slidably connected to one side of the limiting groove 507. A rubber pad 506 is sleeved on the outer wall of the winding sleeve 505. The winding sleeve 505 is threadedly connected to the threaded rod 504. The winding sleeve 505 forms a sliding structure with the processing box 1 through the limiting groove 507. A glass plate 6 is embedded in the front end of the processing box 1, and slide plates 7 are slidably connected to both sides of the curing device body 3 at the top of the processing box 1.

[0028] By adopting the above technical solution, the protective film is allowed to pass through the inlet and outlet 2 to pass through the processing box 1, and is wrapped around the outside of the two winding sleeves 505. The motor 501 fixedly supported by the mounting shell 4 drives the worm 502 to rotate, thereby driving the two worm wheels 503 to drive the corresponding threaded rods 504 to rotate. The two groups of threaded rods 504 have opposite threads, which makes it easy for the two groups of winding sleeves 505 to slide relative to or back to each other, so that the protective film can be stretched during the transportation process to avoid loosening or excessive pulling, thereby improving the applicability and avoiding affecting the production quality of the protective film. The winding sleeves 505 One end is inserted into the limit groove 507 and threadedly connected to the threaded rod 504, and the other end is inserted into the corresponding reserved groove opened in the processing box 1 to facilitate stable sliding. The winding sleeve 505 is sleeved with a rubber pad 506 to increase the friction with the protective film and prevent the metal material from sliding too much and loosening. The curing equipment body 3 is located between the two groups of winding sleeves 505. The curing efficiency of the glue is improved by electron beam curing, thereby improving the composite efficiency. The slide plate 7 is convenient for opening and closing the processing box 1 to adjust and maintain the internal protective film or components, and the glass plate 6 is convenient for viewing the internal working status.

[0029] Specifically, Figure 2 and Figure 4As shown, a supporting platform 8 is fixed on one side of the entrance and exit 2 at both ends of the inner wall of the processing box 1, and a pressing mechanism 9 is arranged on the other side of the supporting platform 8. The pressing mechanism 9 includes a connecting rod 901, and the connecting rod 901 is fixed at both ends of the winding sleeve 505. A lower pressure plate 902 is installed between the two connecting rods 901. The pressing mechanism 9 also includes a damping spring 903, and the damping spring 903 is embedded in the bottom end of the lower pressure plate 902. One end of the damping spring 903 is connected to a connecting shell 904, and the two axial directions of the connecting shell 904 are rotatably connected to the outer wall with a roller 905. The structure of the connecting shell 904 is a U-shaped structure, and the connecting shell 904 forms an elastic structure with the damping spring 903 and the lower pressure plate 902.

[0030] By adopting the above-mentioned technical solution, when the protective film passes through the entrance and exit 2, it is attached to one side of the outer wall of the supporting platform 8. When the winding sleeve 505 moves according to the tensioning adjustment, the lower pressure plate 902 is driven to move toward the supporting platform 8 through the connecting rod 901, and the connecting shell 904 is elastically pushed by the damping spring 903, so that the roller 905 slides and contacts the protective film, further pressing the protective film to avoid wrinkles and warping, while improving the smoothness of the sliding process.

[0031] Working principle: the protective film is passed through the processing box 1 through the entrance and exit 2, the top slide plate 7 is closed to place and adjust the protective film in the processing box 1, and the motor 501 embedded in the mounting shell 4 works, driving the worm 502 to allow the two sets of worm wheels 503 to drive the corresponding threaded rods 504 to rotate. The threads of the two sets of threaded rods 504 are opposite, so that the corresponding two sets of winding sleeves 505 can slide stably relative to or opposite to each other along the limit groove 507, thereby tensioning the protective film. The curing equipment body 3 between the two winding sleeves 505 improves the composite efficiency by curing the glue with an electron beam. The winding sleeve 505 improves the friction force through the rubber pad 506 to avoid loosening due to excessive sliding. The internal processing is convenient to observe through the glass plate 6. The protective film is attached to the corresponding bearing platform 8 when entering and exiting the two entrances and exits 2. Driven by the winding sleeve 505, the connecting rod 901 drives the lower pressure plate 902 to move, so that the damping spring 903 elastically pushes the connecting shell 904, allowing the roller 905 to slide against the protective film for further compression.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
