Description

Technical Field

[0001] The utility model relates to the technical field of parts of reflective film production equipment, in particular to a rolling roller integrating encapsulation and lettering. Background Art

[0002] Reflective films are often used as part of transportation tools or safety warning signs at night or in low-light environments. The principle is to use optical principles to retro-reflect light back to the light source. Usually, reflective films have multiple layers, and the multiple layers need to be laminated and encapsulated during the manufacturing process. Due to different actual application requirements, various colors can also be coated on the reflective film. Since the reflective film itself has good weather resistance and a flat surface, various patterns and texts can be made on the surface of the reflective film for some special requirements.

[0003] For example, in the Chinese invention patent document with the publication number CN115521722B, which discloses the production process of a high-brightness reflective film. In its technical solution, a first roller group 2 and a second roller group 3 with different rotation speeds are used to perform surface treatment on the reflective film layer. Combined with the bumps on the roller body 21, grooves 103 with a large bottom and a small mouth are formed on the surface of the transparent PET layer 101, facilitating the adhesion of UV resin during subsequent processing and improving the bonding strength of the product.

[0004] However, the existing encapsulation roller only has a single function of laminating and encapsulating. When lettering needs to be engraved on the reflective film, separate engraving treatment is required. After engraving, it is also necessary to manually tear off the excess waste, which is rather troublesome, wastes a lot of manpower, and results in too low production efficiency. Summary of the Utility Model

[0005] To overcome the technical defects existing in the prior art, the utility model provides a rolling roller integrating encapsulation and lettering, which directly uses the part with font engraving marks on the roller body to encapsulate and print the reflective film during encapsulation, greatly saving the reflective film processing procedures and reducing the manual operation steps.

[0006] The technical solution adopted by the present utility model is as follows: a rolling press roller integrating encapsulation and lettering, including a roller body formed by sequentially butting a head component, a middle component, and a tail component. The two ends of the roller body require external equipment to provide rotational force and need to cooperate with other roller bodies to provide the necessary pressure. The number of the middle components is more than one, and the middle components can be replaced according to requirements. The detachable method can also facilitate the replacement and repair of components. A central tube extending towards the head component is fixed on the tail component. Lettering rings are provided on the outer surfaces of the head component, the middle component, and the tail component. In actual use, according to the engraving requirements, the middle rings engraved with different font styles are replaced and combined. One end of the central tube extends outside the head component, and a clamping mechanism for fixing the head component is provided on the central tube. The clamping mechanism is used to fix each component on the tail component.

[0007] Preferably, an external connection seat is provided on the central tube, and the external connection seat needs to be communicated with the central tube. An adsorption component is provided on the external connection seat. The adsorption component can tear off the redundant reflective film after engraving the font. The clamping mechanism includes a rotary connection seat fixed on the outer wall of one end of the central tube extending outside the head component, and a locking ring is movably installed on the rotary connection seat by a threaded manner.

[0008] Preferably, in order to facilitate contacting the surface of the reflective film and thus better pull up the reflective film, the adsorption components are uniformly arranged on the outer wall of the central tube. The adsorption component includes a hollow rod, a clamping head is fixed at the top of the hollow rod, and a contact ring shell is slidably sleeved on the clamping head. A return spring is connected between the contact ring shell and the clamping head.

[0009] Preferably, in order to facilitate the installation and replacement of the adsorption component, a flared opening is provided inside the clamping head, a tool slot is provided at the bottom of the flared opening, an outward convex edge is provided at the top of the clamping head, and semi-embedded slots for clamping the adsorption component are provided on the sides of the head component, the middle component, and the tail component.

[0010] Preferably, in order to facilitate providing negative pressure for the rotating adsorption component, an air inlet part is provided at one end of the central tube, air inlet holes are opened on the outer wall of the air inlet part, a gas distribution shell is rotatably clamped outside the air inlet part, the inner wall of the gas distribution shell is close to the outer surface of the air inlet part, a negative pressure port is opened on the outer wall of the gas distribution shell, and a space cavity is opened on the inner wall of the gas distribution shell at the negative pressure port.

[0011] Preferably, in order to make the combination between components more stable, a side groove for the locking ring to be embedded is provided on the side wall of the head component, and a screwing plate is fixed on the side wall of the locking ring. The screwing plate can facilitate manual operation.

[0012] Preferably, for the stable docking between components, the middleware is an annular body, and protruding columns and grooves are evenly arranged on both side surfaces of the middleware, and the protruding columns and the grooves on both sides can be correspondingly fitted and clamped, and the protruding columns and the grooves are only arranged on one side of the head component and the tail component.

[0013] The beneficial effects of the present utility model are as follows: When in use, an external roller is used in cooperation with the roller body of the present utility model, so that the roller body can press and encapsulate the reflective film. In some cases, when hot pressing is required, an additional heat source can be provided to heat the roller body.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] As Figures 1-8 shown, the present embodiment provides a rolling roller integrating encapsulation and lettering, including a roller body formed by sequentially docking a head member 1, an intermediate member 2, and a tail member 3. Rotating force needs to be provided by external equipment at both ends of the roller body, and it needs to cooperate with other roller bodies to provide necessary pressure. The number of intermediate members 2 is more than one, and the intermediate members 2 can be replaced according to requirements. The detachable method can also facilitate the replacement and maintenance of components. A central tube 4 extending towards the head member 1 is fixed on the tail member 3. Lettering rings 5 are provided on the outer surfaces of the head member 1, the intermediate member 2, and the tail member 3. In actual use, the intermediate rings engraved with different font styles are replaced and combined according to the engraving requirements. One end of the central tube 4 extends outside the head member 1. A clamping mechanism 6 for fixing the head member 1 is provided on the central tube 4. The clamping mechanism 6 is used to fix each component on the tail member 3. An external connection seat 403 is provided on the central tube 4, and the external connection seat 403 needs to be communicated with the central tube 4. An adsorption component 7 is provided on the external connection seat 403. The adsorption component 7 can tear off the redundant reflective film after engraving the font. The clamping mechanism 6 includes a rotary connection seat 601 fixed on the outer wall of one end of the central tube 4 extending outside the head member 1. A locking ring 602 is movably installed on the rotary connection seat 601 by a threaded manner. In use, an external roller is used in cooperation with this roller body, so that the roller body can press and encapsulate the reflective film. In some cases, when hot pressing is required, an additional heat source can be provided to heat this roller body. When pressing and encapsulating, the lettering ring 5 can engrave the reflective film. At this time, the reflective film is still attached to the base layer of the reflective film. Then, it is necessary to use the adsorption component 7 to tear off the redundant reflective film. Moreover, the adsorption component 7 is easy to install and can still be freely replaced after the roller body is assembled.

[0026] The adsorption components 7 are evenly arranged on the outer wall of the central tube 4. The adsorption component 7 includes a hollow rod 701. A clamping joint 702 is fixed at the top end of the hollow rod 701. A contact ring shell 703 is slidably sleeved on the clamping joint 702. A return spring 704 is connected between the contact ring shell 703 and the clamping joint 702, which can facilitate contacting the surface of the reflective film, so as to better pull up the reflective film. There is a flared opening inside the clamping joint 702, and a tool slot 705 is provided at the bottom of the flared opening. The top of the clamping joint 702 is provided with a convex edge. Semi-embedded grooves for clamping the adsorption component 7 are provided on the sides of the head component 1, the middle component 2, and the tail component 3, which can facilitate the installation and replacement of the adsorption component 7. One end of the central tube 4 is provided with an air inlet part 401. Air inlet holes are opened on the outer wall of the air inlet part 401. An air distribution shell 402 is rotatably clamped outside the air inlet part 401. The inner wall of the air distribution shell 402 is close to the outer surface of the air inlet part 401. A negative pressure port is opened on the outer wall of the air distribution shell 402, and a space cavity is opened on the inner wall of the air distribution shell 402 at the negative pressure port, which can facilitate providing negative pressure for the rotating adsorption component 7. The negative pressure can suck out the air in the hollow tube through the central tube 4, so that the clamping joint 702 continuously sucks in external air. When in use, due to the rapid flow of air, the contact ring shell 703 can be pressed against the reflective film, and as the roller rotates, the tearing effect can be achieved. In application, if the reflective film is bent as a whole, an external tool is needed to pull out the base layer of the reflective film together with the font style part, so as to ensure the smooth tearing of the redundant part.

[0027] Since negative pressure is continuously maintained in the central tube 4, this causes unnecessary waste of resources. A cross plate can be arranged in the central tube 4. The cross plate can divide the central tube 4 into four separate spaces. The external connection base 403 is placed on the outer wall of the central tube 4 between the cross plates. In this way, during operation, only the external connection base 403 near the negative pressure port can obtain negative pressure.

[0028] A side groove for fitting and embedding the locking ring 602 is provided on the side wall of the head component 1. A screwing plate is fixed on the side wall of the locking ring 602, and the screwing plate can facilitate manual operation, which can make the combination of components more stable.

[0029] The middle component 2 is an annular body. Protrusions and grooves are evenly arranged on both side surfaces of the middle component 2, and the protrusions and grooves on both surfaces can be correspondingly fitted and clamped. The head component 1 and the tail component 3 are only provided with protrusions and grooves on one side, which can facilitate the stable docking between components.

[0030] In use, an external roller is used in cooperation with this roller body, enabling the roller body to perform press-fitting and encapsulation on the reflective film. In some cases, when hot press-fitting is required, an additional heat source can be provided to heat this roller body. The head component 1, the middle component 2, and the tail component 3 on this roller body are docked in sequence, facilitating maintenance and disassembly. Moreover, different font styles can be replaced and combined according to needs. Also, after engraving, the adsorption component 7 can tear off the excess reflective film, and the adsorption component 7 itself is easy to replace and install. Just use a tool to screw the hollow rod 701 onto the external socket 403 on the central tube 4, which is more convenient for subsequent maintenance and replacement.
