[0008] As a further embodiment of this utility model, the support roller seat also includes: a fixed roller seat, which is fixed to the top of the support roller seat by fixing screws; a winding roller, which rotates between the support roller seat and the fixed roller seat; a fixed insert A, which is fixed to the bottom of the support roller seat; and a fixed groove A, which is formed on one side of the fixed insert A.

[0009] As a further embodiment of this utility model, the rubber roller seat also includes: a rubber roller side seat, which is integrally disposed on one side of the rubber roller seat; a rubber roller fixing seat, which is fixed to the top of the rubber roller seat and the rubber roller side seat by fixing screws; a double-sided rubber roller, which rotates between the rubber roller seat, the rubber roller side seat and the rubber roller fixing seat; a limiting roller, which rotates on the other side of the rubber roller seat; a fixing block B, which is fixed to the bottom of the rubber roller seat; and a fixing groove B, which is formed on one side of the fixing block B.

[0010] As a further embodiment of this utility model, a lower pressure roller is rotatably mounted in the lower center of the pressure roller seat; the pressure roller seat includes: a pressure roller support frame, which is integrally mounted on the front end of the top of the pressure roller seat; a pressure roller fixing seat, which is fixed to the top of the pressure roller support frame by fixing screws; a film-coating roller, which rotates between the pressure roller fixing seat and the pressure roller support frame; a film-coating guide roller, which rotates at the front end of the pressure roller support frame; an adjusting bracket, which is integrally mounted on the top of the pressure roller seat; an adjusting slider A, which slides inside the adjusting bracket; an adjusting screw A is rotatably mounted on the top of the adjusting slider A; the adjusting screw A is threadedly connected to the adjusting bracket; and the adjusting slider A rotates to one side of the adjusting pressure roller A.

[0011] As a further embodiment of this utility model, the pressure roller seat also includes: a front guide roller A, which rotates at the front end of the adjusting bracket; a rear guide roller A, which rotates at the rear end of the adjusting bracket; a fixed joint, the number of which is set to two, and the fixed joints are symmetrically and integrally arranged on one side of the pressure roller seat; a fixed insert C, which is integrally arranged at the bottom of the fixed joint; and a fixed groove C, which is opened on one side of the fixed insert C.

[0013] The pressing-type inner page insert book label processing machine provided by this utility model has the following beneficial effects:

[0014] When processing machines require maintenance and repair, and components such as support roller seats, rubber roller seats, pressure roller seats, and bonding seats need to be disassembled and repaired, the fixed slider can be moved by simply rotating the fixing screw, thereby allowing the limit block to easily disengage from the fixing groove A of the fixing block A at the bottom of the support roller seat. This greatly reduces the workload and time cost for maintenance personnel. The same principle also applies to the disassembly of rubber roller seats, pressure roller seats, and bonding seats. This unified and efficient disassembly method ensures the smoothness and efficiency of the entire maintenance process.

[0015] In terms of installation, by accurately inserting the fixing block A at the bottom of the support roller seat into the fixing slot and rotating the fixing screw in the opposite direction, the limiting block will automatically lock in the fixing slot A, ensuring a stable and reliable installation. The fixing block A touches the detection block and moves it down, thereby activating the detection module. The module then sends a signal to the external control equipment to confirm that the support roller seat has been correctly installed. This intelligent detection mechanism not only improves the installation accuracy but also effectively avoids operational failures caused by improper installation, enhancing the safety and stability of the machine. The same process is followed for the installation of rubber roller seats, pressure roller seats, and bonding seats, ensuring the consistency and accuracy of all key components during the installation process. This installation mechanism, which integrates automatic detection functions, not only simplifies the operation process but also improves the level of intelligence in maintenance work, making the maintenance and management of the entire processing machine more efficient and precise.

[0038] The specific usage and function of this embodiment are as follows: By placing the label inside the card issuing mechanism 102, the bottom page is placed on the roller 202. The double-sided adhesive roller 303 has thin strips of double-sided adhesive, which can stick the inner page to the bottom page. The label magazine of the card issuing mechanism 102 is lower in the front and higher in the back. When pressure is applied above the label magazine by the cylinder on the card issuing mechanism 102, the front 10mm of the label is adhered to the double-sided adhesive of the bottom page, and the back of the label is blocked by a baffle and separated from the bottom page. When no pressure is applied above the label magazine, the label magazine will... As the cylinder lifts the label by 1mm, the bottom label is already adhered to the double-sided tape and will not rise with the label magazine. Instead, it moves forward with the label and bottom page along with the machine. The laminating roller 403 then laminates the label and bottom page. By adjusting the pressure roller A408 and the lower pressure roller of the pressure roller seat 4, the laminated film, label, and bottom page are pressed together, locking the book inside the label. The die-cutting mechanism 103 then uses the cylinder to drive the mold to die-cut the book label into the required shape, and finally, it is wound up by the rear winding roller 202.

[0039] When the processing machine needs maintenance and repair, such as when the support roller seat 2, rubber roller seat 3, pressure roller seat 4, and adhesive bonding seat 5 need to be disassembled, the fixing screw 110 can be rotated. The fixing screw 110 will drive the fixing slider 108 to move, causing the limiting insert 109 on one side of the fixing slider 108 to disengage from the fixing groove A204 of the fixing insert A203 at the bottom of the support roller seat 2. Therefore, the support roller seat 2 can be disassembled. The other rubber roller seat 3, pressure roller seat 4, and adhesive bonding seat 5 can also be operated in the same way, which facilitates the maintenance and disassembly of the processing machine. When the support roller seat 2, rubber roller seat 3, pressure roller seat 4, and adhesive bonding seat 5 need to be installed, the fixing insert A203 at the bottom of the support roller seat 2 can be inserted into the fixing slot 10. Within 7, the fixing screw 110 is rotated in the opposite direction. The fixing screw 110 will drive the limiting plug 109 to be inserted into the fixing slot A204 to fix the support roller seat 2. When the fixing plug A203 is inserted into the fixing slot 107, the fixing plug A203 will touch the detection block 112 to move downward, causing the bottom of the detection block 112 to trigger the detection module 113. The detection module 113 will then send a signal to the external control device. When the external control device receives the signal, it indicates that the support roller seat 2 is installed in the specified position. The installation operations of the rubber roller seat 3, pressure roller seat 4, and bonding seat 5 are the same as those of the support roller seat 2, which facilitates maintenance and also allows for the detection of the installation positions of the support roller seat 2, rubber roller seat 3, pressure roller seat 4, and bonding seat 5.

[0040] The above description is merely an exemplary embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The scope of protection of the present utility model is determined by the appended claims.
