Description

Technical Field

[0001] This utility model relates to a film-applying conveyor structure. Background Technology

[0002] During the production of acrylic glass, the upper and lower surfaces need to be coated with film. Traditionally, the glass is transported from the conveyor roller to the pressure roller. During the process of passing through the pressure roller, the film on the upper and lower surfaces is pressed onto the acrylic glass surface. Because there is a certain height difference between the pressure roller and the conveyor roller on the conveyor roller, the glass will shake when passing through the pressure roller, so the coating is prone to wrinkles, which affects the coating effect. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a film-applying conveyor structure that can prevent vibration when the plexiglass passes through the pressure roller, thus ensuring the quality of film application.

[0004] To achieve this objective, the structure adopted in this utility model is as follows: a film-applying conveyor frame structure, including a main support frame, a pressure roller assembly is arranged in the center of the main support frame, the pressure roller assembly includes an upper pressure roller and a lower pressure roller arranged symmetrically above and below, multiple parallel conveyor rollers are arranged in front of the pressure roller assembly, a lifting roller is arranged between the pressure roller assembly and the conveyor rollers, the top height of the lifting roller is higher than the top height of the conveyor rollers, a fixed pressure roller is arranged between the lifting roller and the conveyor rollers; a material shaft assembly is arranged behind the pressure roller assembly, the material shaft assembly includes an upper material shaft and a lower material shaft arranged symmetrically above and below, the two ends of the upper material shaft are connected to the main support frame through a first support frame, and the two ends of the lower material shaft are connected to the main support frame through a second support frame; multiple parallel conveyor rollers are arranged behind the material shaft assembly.

[0005] The lifting roller is connected to the main support at both ends via a lifting connecting frame, which is driven to lift by an electric cylinder.

[0006] The first and second supports are screw lifting supports.

[0007] The surface of the lifting roller is provided with a sponge roller sleeve.

[0008] Its beneficial effects are as follows: The structure of this utility model is reasonable and ingenious. The acrylic glass is conveyed between the upper and lower pressure rollers on the conveyor roller. When it passes the lifting roller, the front end of the acrylic glass tilts up and enters between the upper and lower pressure rollers. The upper and lower films on the upper and lower feeding shafts are pressed onto the surface of the acrylic glass. The tail end of the acrylic glass is pressed down by the constant pressure roller to prevent it from shaking. The acrylic glass remains stable throughout the entire film application process, ensuring the quality of the film application. The acrylic glass falls onto the conveyor rollers behind the upper and lower feeding shafts and continues to be conveyed. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] like Figure 1The film-applying conveyor structure shown includes a main support 1. A pressure roller assembly is centrally located on the main support 1. The pressure roller assembly includes an upper pressure roller 3 and a lower pressure roller 4 symmetrically arranged vertically. Both ends of the upper or lower pressure roller 3 are connected to the main support 1 via cylinders. The upper or lower pressure roller 4 is connected to a motor for rotation. Multiple parallel conveyor rollers 2 are arranged in front of the pressure roller assembly. The conveyor rollers 2 rotate via a conveyor chain or belt mounted on the main support 1, moving the acrylic glass placed on them. The horizontal height of the gap between the upper pressure roller 3 and the lower pressure roller 4 is higher than the horizontal height of the conveyor roller 2. A lifting roller 7 is positioned between the pressure roller assembly and the conveyor roller 2. The top height of the lifting roller 7 is higher than the top height of the conveyor roller 2. When the acrylic glass passes through the lifting roller 7, one end tilts upwards and enters the gap between the upper pressure roller 3 and the lower pressure roller 4. A constant pressure roller 5 is installed between the lifting roller 7 and the conveying roller 2. When the acrylic glass passes through the pressure roller group, the tail end will vibrate under pressure. The constant pressure roller 5 presses down to prevent the tail end of the acrylic glass from excessively lifting and vibrating. A material shaft group is installed behind the pressure roller group. The material shaft group includes an upper material shaft 10 and a lower material shaft 12 arranged symmetrically. The two ends of the upper material shaft 10 are connected to the main support 1 through the first bracket 9, and the two ends of the lower material shaft 12 are connected to the main support 1 through the second bracket 13. The upper film roll is placed on the upper material shaft 10, and the lower film roll is placed on the lower material shaft 12. The upper film is wound on the upper pressure roller 3, and the lower film is wound on the lower pressure roller 4. When the acrylic glass passes through the pressure roller group, the upper and lower films are adhered to the upper and lower surfaces of the acrylic glass. Multiple parallel conveying rollers 2 are arranged behind the material shaft group.

[0015] The lifting roller 7 is connected to the main support 1 at both ends through the lifting connecting frame 6. The lifting connecting frame 6 is driven to lift by an electric cylinder. The height of the pressure roller is adjusted by the electric cylinder according to the different thicknesses of the glass and the length of the glass.

[0016] The first support 9 and the second support 13 are screw lifting supports, and the height of the first support 9 and the second support 13 is adjusted by the screw according to the thickness of the film roll.

[0017] The surface of the lifting roller 7 is provided with a sponge roller sleeve. Under the pressure of the pressure roller group and the constant pressure roller 5, the plexiglass will undergo a certain deformation. The sponge roller sleeve can provide a certain cushioning effect to prevent the plexiglass from being pressed into cracks.

[0018] The lifting roller 7 can be set as an eccentric roller with a silicone roller sleeve on its surface. The silicone roller sleeve has a certain adhesive force. When no acrylic glass passes by, the heavier side faces downward under the action of gravity. When acrylic glass passes by, the eccentric roller rotates under the action of friction. At the same time, the silicone roller sleeve can stick away the dust particles on the surface of the acrylic glass. During the rotation of the eccentric roller, the acrylic glass is slowly lifted. When the acrylic glass is fed into the pressure roller group, the center height of the gap between the pressure roller group is set to be higher than that of the eccentric roller, and the acrylic glass will separate from the lifting roller, reducing the deformation of the acrylic glass.

[0019] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
