Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a printing roller transmission mechanism. Background Technology

[0002] Printing is a technology that involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials like paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressure application. It involves mass-producing copies of the original content. Printing is the process of transferring approved printing plates onto the substrate using printing machinery and specialized inks. A printing roller is a cylindrical accessory used in printing equipment for plate making, also called a plate cylinder or steel roller. The cylinder is the main part of the printing roller, usually a hollow or solid cylinder, typically made of metal such as steel or aluminum alloy, possessing sufficient strength and rigidity to withstand printing pressure and friction during the printing process. The surface of the cylinder is usually plated with copper because copper has good electrical conductivity and engraving properties, facilitating subsequent pattern engraving using an electronic engraving machine. After engraving, a layer of chromium is plated onto the copper layer. The chromium layer improves the hardness, wear resistance, and corrosion resistance of the printing roller, extending its service life, and also helps improve printing quality, making the printed pattern clearer and more durable.

[0003] In current applications of printing rollers, the "male and female head" is a connecting structural component. In some printing roller application systems, the male and female head is used to connect the printing roller and the drive device. However, during the installation process, there is a certain axial deviation between the male and female heads, which leads to axial transmission and damages the equipment. Utility Model Content

[0006] The above technical solution employs two symmetrically arranged drive support cylinders. The output ends of these cylinders pull the positioning plate for the locking hook fixing sleeve and the fixing sleeve for the plate cylinder drive locking hook, facilitating changes in their positions. Furthermore, the annular design of the positioning plate for the locking hook fixing sleeve facilitates its installation with the plate cylinder drive locking hook fixing sleeve.

[0007] Preferably, the positioning pull plate of the locking hook fixing sleeve and the fixing sleeve of the plate cylinder transmission locking hook form a rotatable connection.

[0008] By adopting the above technical solution, the rotatable connection between the positioning pull plate of the locking hook fixing sleeve and the fixing sleeve of the plate cylinder drive locking hook facilitates the axial rotation of the fixing sleeve of the plate cylinder drive locking hook, thereby enabling normal operation.

[0009] Preferably, a positioning connecting spring is provided between the fixing sleeve for the plate cylinder drive lock hook and the connecting female head for the plate cylinder, and the positioning connecting spring is a wave spring.

[0010] By adopting the above technical solution, the positioning connecting spring installed between the fixed sleeve of the plate cylinder drive lock hook and the connecting female head of the plate cylinder, and the waveform design of the positioning connecting spring, facilitates the buffer connection between the fixed sleeve of the plate cylinder drive lock hook and the connecting female head of the plate cylinder, thereby improving the stability of the device.

[0011] Preferably, the outer surface of one end of the male connector for the printing plate cylinder is inclined, and a limit stop is provided at one end of the inclined design of the male connector for the printing plate cylinder.

[0012] By adopting the above technical solution, the outer surface of one end of the male connector for the printing plate cylinder is designed to be inclined, which facilitates docking with the inclined design of the female connector for the printing plate cylinder, thereby improving the stability of the connection. The limiting block set at one end of the inclined design of the male connector for the printing plate cylinder facilitates the installation of the locking hook for the printing plate cylinder drive, thereby improving the convenience of installing the locking hook for the printing plate cylinder drive and increasing the guiding effect.

[0013] Preferably, the inner wall of one end of the female connector for the printing plate cylinder is inclined, and the inclined design of the female connector for the printing plate cylinder corresponds to the inclined design of the male connector for the printing plate cylinder.

[0014] By adopting the above technical solution, the inner wall of one end of the female connector for the printing plate cylinder is designed to be inclined, which facilitates the corresponding installation of the inclined design of the female connector for the printing plate cylinder and the inclined design of the male connector for the printing plate cylinder. This increases the contact area of ​​the connection, thereby improving practicality and contributing to the stability of the connection.

[0015] Preferably, the outer surface of the male connector for the printing plate cylinder is provided with a groove, and the groove of the male connector for the printing plate cylinder is engaged with the locking hook for the printing plate cylinder drive.

[0016] By adopting the above technical solution, the slot on the outer surface of the male connector for the printing plate cylinder facilitates the connection between the male connector for the printing plate cylinder and the locking hook for the printing plate cylinder drive. After the locking hook for the printing plate cylinder drive is engaged, the stability of the connection between the female connector for the printing plate cylinder and the male connector for the printing plate cylinder will be improved.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the roller transmission mechanism of this plate:

[0018] 1. The device is equipped with a drive support cylinder and a positioning pull plate for fixing the hook. When the device is working, the drive support cylinder can easily pull the positioning pull plate for fixing the hook. The setting of two drive support cylinders will improve the uniformity of pulling the positioning pull plate for fixing the hook, and facilitate the sliding of the positioning pull plate for fixing the hook of the plate cylinder drive lock. This makes it easier to change the distance between the fixing sleeve for fixing the hook of the plate cylinder drive lock and the female connector of the plate cylinder, thereby facilitating the adjustment of the female connector of the plate cylinder and the male connector of the plate cylinder, and increasing the adjustment convenience of the device.

[0019] 2. A positioning connecting spring and a female connector for the printing plate cylinder are provided. When the device is working, the positioning pull plate of the hook fixing sleeve drives the fixing sleeve of the printing plate cylinder transmission lock hook to slide. Subsequently, the positioning connecting spring directly presses the fixing sleeve of the printing plate cylinder transmission lock hook and the female connector for the printing plate cylinder to deform, which facilitates the installation of the locking hook for the printing plate cylinder transmission. The inclined surface design between the female connector and the male connector for the printing plate cylinder increases the contact area between the female connector and the male connector for the printing plate cylinder, thereby improving the connection stability of the female connector and the male connector for the printing plate cylinder.

[0020] 3. The device is equipped with a male connector for the printing cylinder and a locking hook for the printing cylinder drive. When the device is working, the locking hook for the printing cylinder drive is installed, and then the support cylinder is driven to release, which facilitates the automatic reset of the positioning connection spring.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figure 1-2 This utility model provides a technical solution: a printing roller transmission mechanism, including a drive support cylinder 1, a locking hook fixing sleeve positioning pull plate 2, a printing roller transmission locking hook fixing sleeve 3, a positioning connecting spring 4, a printing roller connecting female head 5, a printing roller connecting male head 6, a printing roller transmission locking hook 7, a printing roller body 8, and a motor connector 9. The drive support cylinder 1 has a locking hook fixing sleeve positioning pull plate 2 fixedly connected to its output end. The two drive support cylinders 1 are symmetrically arranged. The locking hook fixing sleeve positioning pull plate 2 has a ring design. The locking hook fixing sleeve positioning pull plate 2 and the printing roller transmission locking hook fixing sleeve 3 form a rotatable connection. When using this device, the printing roller connecting male head 6 is first fixedly connected to one end of the printing roller body 8, and the printing roller connecting female head 5 is fixedly installed at the output end of the motor connector 9.

[0026] The surface of the positioning pull plate 2 for the locking hook fixing sleeve is provided with an opening, and the inner wall of the opening of the positioning pull plate 2 for the locking hook fixing sleeve is provided with a plate cylinder transmission locking hook fixing sleeve 3. The surface of the plate cylinder transmission locking hook fixing sleeve 3 is provided with an opening, and the inner wall of the opening of the plate cylinder transmission locking hook fixing sleeve 3 is installed with a plate cylinder connecting female head 5. A positioning connecting spring 4 is provided between the plate cylinder transmission locking hook fixing sleeve 3 and the plate cylinder connecting female head 5. The positioning connecting spring 4 is a wave spring. The plate cylinder transmission locking hook fixing sleeve 3 is installed on the outer surface of the plate cylinder connecting female head 5. Drive support cylinders 1 are respectively provided at both ends of the plate cylinder transmission locking hook fixing sleeve 3. The drive support cylinders 1 drive the plate cylinder transmission locking hook fixing sleeve 3 to move, so that the plate cylinder transmission locking hook fixing sleeve 3 drives the plate cylinder connecting female head 5 to move, so that the positioning connecting spring 4 between the plate cylinder connecting female head 5 and the plate cylinder transmission locking hook fixing sleeve 3 can be deformed.

[0027] The surface of the female connector 5 for the printing cylinder is provided with an opening, and the inner wall of the opening of the female connector 5 for the printing cylinder is installed with a male connector 6 for the printing cylinder. The outer surface of the positioning pull plate 2 for the locking hook fixing sleeve is provided with a locking hook 7 for the printing cylinder drive. The outer surface of one end of the male connector 6 for the printing cylinder is designed with an inclination. One end of the inclination design of the male connector 6 for the printing cylinder is provided with a limit stop. After the fixing sleeve 3 for the locking hook for the printing cylinder drive slides, one end of it will approach the printing cylinder body 8. Then, the locking hook 7 for the printing cylinder drive is installed in the opening at this end of the fixing sleeve 3 for the locking hook for the printing cylinder drive, so that the locking hook 7 for the printing cylinder drive can be engaged in the groove of the male connector 6 for the printing cylinder.

[0028] The male connector 6 for the printing plate cylinder has an opening on its surface, and the printing plate cylinder body 8 is located at one end of the opening. A motor connector 9 is installed at one end of the opening of the fixing sleeve 3 for the printing plate cylinder drive lock hook. The inner wall of one end of the female connector 5 for the printing plate cylinder is inclined, and this inclined design corresponds to the inclined design of the male connector 6. The outer surface of the male connector 6 has a groove, and this groove engages with the locking hook 7 for the printing plate cylinder drive, ultimately driving the support cylinder. 1. Releasing the pressure loosens the positioning pull plate 2 and the plate cylinder drive locking hook fixing sleeve 3. Subsequently, the positioning connecting spring 4 automatically resets, facilitating the movement of the plate cylinder drive locking hook fixing sleeve 3. This causes the plate cylinder drive locking hook fixing sleeve 3 to press against the plate cylinder drive locking hook 7, further improving the tightness of the connection between the plate cylinder connecting female head 5 and the plate cylinder connecting male head 6. The corresponding inclined design between the plate cylinder connecting female head 5 and the plate cylinder connecting male head 6 increases the contact area, effectively increasing friction and preventing displacement.

[0029] Working principle: When using the printing roller transmission mechanism, firstly, two drive support cylinders 1 drive the locking hook fixing sleeve positioning pull plate 2 to move, which facilitates the sliding of the printing roller transmission locking hook fixing sleeve 3. This causes the printing roller transmission locking hook fixing sleeve 3 to protrude from the slot of the printing roller connecting male head 6. The printing roller transmission locking hook 7 passes through the printing roller transmission locking hook fixing sleeve 3 and engages with the slot of the printing roller connecting male head 6, thereby improving the stability of the printing roller connecting female head 5 and the printing roller connecting male head 6. The printing roller connecting female head 5 is connected to the motor connector 9, and the printing roller connecting male head 6 is connected to one end of the printing roller body 8. The inclined surfaces between the printing roller connecting female head 5 and the printing roller connecting male head 6 make contact, thereby increasing the contact area for friction and anti-slip, and increasing the overall practicality.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
