Description

Technical Field

[0001] The invention belongs to the technical field of die cutting and relates to a method and equipment for synchronously preparing a self-contained film in a cycle of an optical film sandwich handle. Background Art

[0002] The protective film is generally composed of a functional surface + a release film. The customer adds a color block handle for easy tearing and use. The color block adhesive surface is attached to the functional adhesive surface of the protective film. The production process of the color block adhesive surface being attached to the functional surface Figure 1 As shown: the raw material 23 is discharged by the third unloading device 14, and the raw material 23 is separated into the release film 26 with the raw material after separation, and the release film 26 with the raw material is rolled up and discarded by the third receiving device 19. The separated functional film enters the first pair of presses 17, and at the same time, the second unloading device 13 outputs the handle color block tape 22 and enters the first pair of presses 17. In addition, the newly prepared release film 21 needs to be purchased with the same parameters and weight as the release film 26 with the raw material. The newly prepared release film 21 is discharged by the first unloading device 11, and then enters the first pair of presses 17 after passing through the first deviation corrector 12. Then, the newly prepared release film 17, the handle color block tape 22 and the separated functional film enter the first pair of presses 17 together, and enter the first cutting device 18 for cutting after pressing.

[0027] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0028] The present embodiment proposes a method for circularly and synchronously preparing an optical film sandwich handle with a self-contained film, comprising peeling off the release film 43 of the original material, separating the release film 43 of the original material and the functional film, recycling the release film 43 of the original material, attaching a handle color block tape 41 to the adhesive surface of the functional film, returning the release film 43 of the original material and pressing the functional film, the handle color block tape 41 and the release film 43 of the original material against each other, and forming a product 45 after cutting.

[0029] The method utilizes the release film 43 that comes with the raw material. In the process of laminating the functional film to the handle color block tape 41, the release film 43 that comes with the raw material is recycled and reused, so that the release film 43 that comes with the raw material is fully utilized to save costs and avoid problems caused by improper selection. The clever combination is simple and practical, and the purchase, processing and cutting steps of the new film are reduced. The sandwich handle is recycled to effectively avoid foreign matter. The cyclic masking process forms a shield, so that even foreign matter cannot enter the functional surface, reducing the risk of customer complaints.

[0030] The above method is generally applicable to sandwich-type handle optical films.

[0031] like Figure 2 As shown, the above method can be implemented by a variety of equipment. This embodiment also proposes an optical film sandwich handle with self-contained film circulating synchronous preparation equipment, including a fourth discharge device 31, a fourth receiving device 32, a fifth receiving device 33, a fifth discharge device 34, a press 36 and a cutting device 37, wherein the fourth discharge device 31 is used to discharge the raw material 42, the raw material 42 is separated to form a functional film and the raw material self-contained release film 43, the raw material self-contained release film 43 passes through the guide wheel group 35 and then enters the press 36, and the fifth discharge device 34 is used to discharge the handle color block tape 41.

[0032] The functional film, handle color block tape 41 and the release film 43 of the original material are simultaneously input into the pressing machine 36 for pressing and then input into the cutting device 37. The cut products 45 are rolled up by the fifth material receiving device 33, and the cut waste materials 44 are rolled up by the fourth material receiving device 32.

[0033] Specifically, Figure 2 As shown, a front guide device 39 is provided in front of the input end of the press 36, and the front guide device 39 is used to guide the raw material self-contained release film 43 separated from the raw material 42 to the press 36. The raw material self-contained release film 43 can be positioned at a height position after being guided by the front guide device 39, and the raw material self-contained release film 43 can be flattened and wrinkles and curved surface parts can be eliminated at the same time, so that the raw material self-contained release film 43 guided by the front guide device 39 can be smoothly input to the input end of the press 36.

[0034] A rear guide device 310 is provided behind the cutting device 37. The rear guide device 310 is used to guide the product 45 to separate from the waste material 44 so that the separation positions of the product 45 and the waste material 44 are spaced apart. The guiding position of the rear guide device 310 is horizontally consistent with the cutting position of the cutting device 37. Therefore, the waste material 44 output by the cutting device 37 is directly rolled up by the fourth receiving device 32, and the product 45 is rolled up by the fifth receiving device 33 after being guided by the rear guide device 310, so as to avoid product wrinkles during the rolling process caused by the speed difference between the fourth receiving device 32 and the fifth receiving device 33, thereby reducing the generation of waste material.

[0035] The optical film sandwich handle self-contained film circulation synchronous preparation device also includes a guide wheel group 35, which is used to guide the raw material self-contained release film 43 separated from the raw material 42 back to the pressing machine 36. The guide wheel group 35 includes a plurality of guide rollers, which are arranged in an "L" shape, and the guide rollers are located in front of the input end of the pressing machine 36. In this embodiment, the guide wheel group 35 includes three horizontally arranged guide rollers, and the height of the three horizontally arranged guide rollers is on the same horizontal line as the fourth unloading device 31, the fourth receiving device 32 and the fifth receiving device 33.

[0036] The guide wheel group 35 also includes a deviation corrector. Another guide roller in the guide wheel group 35 is below the deviation corrector. This arrangement allows the release film 43 of the original material to remain in a taut state, thereby preventing the release film 43 of the original material from wrinkling.

[0037] In addition, since the output speed of the raw material 42 and the output speed of the release film 43 attached to the raw material are kept matched, it is possible to further avoid the generation of wrinkles when the release film 43 attached to the raw material is input.

[0038] Preferably, the pressing position of the pressing machine 36 and the cutting position of the cutting device 37 are in the same horizontal plane, and the fourth unloading device 31, the fourth receiving device 32 and the fifth receiving device 33 are sequentially arranged above the pressing machine 36 and the cutting device 37. In this arrangement of the positions of the fourth unloading device 31, the fourth receiving device 32 and the fifth receiving device 33, the strip materials outputted from the raw material 42, the release film 43 of the raw material, the waste material 44, the product 45, etc. are kept tight according to their own weight.

[0039] A separation roller 38 is also provided on one side of the input end of the pressing position of the pressing machine 36 for separating the raw material 42 to form the functional film and the release film 43 of the raw material. In this embodiment, the separation roller 38 is a rotating roller. The effect of the separation roller 38 is to separate the release film 43 of the raw material from the remaining strip material after the raw material passes through the separation roller 38. The separation in this process is the active separation of the raw material 42, which can keep the structure of the separation roller 38 simple.

[0040] The fifth unloading device 34 is arranged in the area between the separation roller 38 and the guide wheel group 35 input to the return material of the pressing machine 36, which is conducive to adding the handle color block tape 41.

[0041] This embodiment only provides a device for the synchronous circulation preparation of an optical film sandwich handle with a self-contained film corresponding to the method for the synchronous circulation preparation of an optical film sandwich handle with a self-contained film. The implementation of the above method is not limited to the device disclosed in this embodiment, and auxiliary equipment, winding equipment and unwinding equipment can also be changed and adjusted according to the requirements of the film and process.

[0042] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
