Description

Technical Field

[0001] This utility model relates to the field of hot glue rollers for laminating machines, and specifically to a hot glue roller for a small laminating mechanism. Background Technology

[0002] Laminating machines can be divided into two main categories: instant laminating machines and pre-coating laminating machines. They are specialized equipment used for paper, boards, and film lamination. After being pressed together by hot glue rollers, they form a paper-plastic composite product.

[0003] Currently, the hot glue rollers of desktop small laminating mechanisms are directly fixed to the mechanism through roller supports and bolts. However, after long-term laminating of paper of different thicknesses, the roller body and the supporting fasteners are prone to loosening, which affects the hot glue effect. Therefore, a hot glue roller for small laminating mechanisms is proposed to avoid the problem of loosening between the roller body and the supporting fasteners and to ensure the hot glue effect. Summary of the Invention

[0004] To address the problems in the prior art, this utility model provides a hot glue roller for a small coating mechanism to avoid loosening between the roller body and the supporting fixing parts, thereby ensuring the hot glue effect.

A constant temperature electric heating rod is uniformly installed around the inner cavity of the hot glue roller body by screws. One end of the hot glue roller body is connected to a first support roller frame through a rotating shaft, and the other end of the hot glue roller body is connected to a second support roller frame through a rotating shaft. A fixing frame is provided on one side of the first support roller frame, and a first support frame and a second support frame are respectively provided on the top of the first support roller frame and the second support roller frame.

[0006] The inner wall of the fixed frame is provided with a slide rail corresponding to the position of the first support roller frame. The telescopic component includes a first support spring and a second support spring. A motor is installed in the inner cavity of the first support roller frame by bolts.

[0008] During operation, the lithium battery inside the hot glue roller body provides power to the constant temperature electric heating rod. The constant temperature electric heating rod heats the inner cavity of the hot glue roller body, so that the hot glue roller body can perform hot pressing and film coating when it comes into contact with paper, etc. At the same time, the hot glue roller body is driven by the motor to rotate to ensure the uniformity of hot pressing.

[0009] The first and second support springs are respectively supported and fixed between the first roller frame and the first support frame, and between the second roller frame and the second support frame, so that when papers of different thicknesses pass through the bottom of the hot glue roller body, the first and second support springs will respectively cooperate with the first roller frame and the second roller frame supported at both ends of the hot glue roller body to move up and down, so as to avoid the easy movement problem between the hot glue roller body and the connecting structure.

[0010] When the first support spring and the second support spring cooperate with the first roller frame and the second roller frame to move up and down, respectively, the slide rail on one side of the fixed frame will cooperate with the first roller frame to move up and down more smoothly.

[0011] Specifically, a lithium battery is bolted to one side of the inner wall of the hot glue roller body, and the input end of the constant temperature electric heating rod is electrically connected to the output end of the lithium battery through a wire.

[0012] By adopting the above technical solution, the lithium battery provides power to the constant temperature electric heating rod during operation, and the constant temperature electric heating rod heats the inner cavity of the hot glue roller body, so that the hot glue roller body is in contact with paper and other materials for hot pressing and film coating.

[0013] Specifically, a first mounting hole is provided on the top surface of the fixing frame corresponding to the position of the first support frame.

[0014] By adopting the above technical solution, the first mounting hole is used to facilitate the mounting of the fixing frame on the small film coating mechanism, and the fixing frame supports and fixes the first support frame.

[0015] Specifically, a second mounting hole is provided on the surface of the second support frame corresponding to the position of the first support frame.

[0016] By adopting the above technical solution, the second mounting hole is used to facilitate the installation of the second support frame on the small film coating mechanism, and the second support frame is used to install and fix the second support spring.

[0017] Specifically, the first support roller frame is slidably connected to the slide rail via a slider on one side, and the motor drive shaft is connected to the rotating shaft of the hot glue roller body.

[0018] By adopting the above technical solution, during operation, the sliding rail assists the first roller frame to move up and down more smoothly, and the hot glue roller body is driven by the motor to rotate, so as to ensure the uniformity of hot pressing.

[0019] Specifically, the first support spring is fixed between the first support roller frame and the first support frame by a support block, and the second support spring is fixed between the second support roller frame and the second support frame by a support block.

[0020] By adopting the above technical solution, when papers of different thicknesses pass through the bottom of the hot glue roller body, the first support spring and the second support spring will respectively cooperate with the first roller frame and the second roller frame supported at both ends of the hot glue roller body to perform lifting and lowering movements, so as to avoid the easy movement problem between the hot glue roller body and the connecting structure.

[0021] The beneficial effects of this utility model are:
