Description

Technical Field

[0001] This invention relates to the field of printing press technology, specifically to a locking support mechanism that facilitates the replacement of printing rollers. Background Technology

[0002] Printing rollers are the core components of printing presses. They are usually cylindrical metal or composite material rollers with surfaces treated by engraving, coating, and other processes. During the printing process, they can transfer ink, support the printing plate, or transport the printing substrate. Through cooperation with the printing plate and pressure rollers, they can achieve image and text transfer, directly affecting the clarity of printed products, ink uniformity, and production efficiency. They are widely used in various printing processes such as offset printing, flexographic printing, and gravure printing.

[0003] Existing printing presses typically use anilox rollers to transfer ink to the image area of ​​the printing plate, then an impression cylinder to transfer the ink to the substrate surface, and finally a drying device to complete the printing process. This eliminates the complex inking roller assembly and water supply system of traditional printing presses, simplifying the structure and making operation convenient. However, when replacing the printing plate roller, it is usually necessary to remove the screws at both ends and then disassemble and replace the entire structure, which is a relatively troublesome process and significantly increases the time cost required for subsequent disassembly and replacement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a locking support mechanism that facilitates the replacement of printing rollers. This solves the problem that replacing printing rollers typically involves disassembling the screws at both ends and then disassembling and replacing the entire structure, which is a cumbersome process and significantly increases the time cost required for subsequent disassembly and replacement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a locking support mechanism for convenient printing roller replacement, comprising a base and a handle, wherein a rotating block is rotatably connected inside the handle, a sliding seat is rotatably connected to the outer wall of the rotating block, a handle is fixedly connected to the outer wall of the sliding seat, the lower surface of the sliding seat is slidably connected to the upper surface of the base, a sliding assembly is fixedly provided on the outer wall of the sliding seat, the sliding assembly includes a sliding block, a fixed rod is slidably connected inside the sliding block, the outer wall of the fixed rod is fixedly connected to the outer wall of the base, and a printing roller body is installed inside the sliding seat.

[0006] The above technical solution involves releasing the limit between the sliding seat and the base by rotating the handle, and then pulling the handle to move the sliding seat and sliding assembly along the base and the fixed rod, thereby quickly disassembling the printing roller body and significantly reducing the time cost required for subsequent replacements.

[0007] Preferably, the sliding assembly further includes a reinforcing block, the outer wall of which is fixedly connected to the outer wall of the sliding seat, and the side of the reinforcing block away from the sliding seat is fixedly connected to the outer wall of the sliding block.

[0008] Preferably, the base has a T-shaped groove inside, and the sliding seat and the T-shaped groove are slidably connected.

[0009] Preferably, an electric slide is installed above the printing roller body. A motor is fixedly installed on the outer wall of the electric slide. An adjustment component is fixedly installed on the drive end of the motor. The adjustment component includes a fixed frame. An electric push rod is fixedly installed on the lower surface of the fixed frame. A connecting rod is fixedly connected to the drive end of the electric push rod. A connecting column is fixedly connected to the outer wall of the connecting rod. A pressure block is fixedly connected to the top of the connecting column. An air bladder is attached to the lower surface of the pressure block. An air guide tube is fixedly installed inside the air bladder. A clamping component is fixedly installed at the end of the air guide tube away from the air bladder.

[0010] Preferably, the adjustment assembly further includes a lead screw, the outer wall of which is fixedly connected to the drive end of the motor, and the end of the lead screw away from the motor is rotatably connected to the inside of the electric slide table. The outer wall of the lead screw is threadedly connected to a threaded block, and the outer wall of the fixing frame is rotatably connected to the inside of the threaded block.

[0011] Preferably, the clamping assembly includes a piston tube, the end of the air guide tube away from the airbag is fixedly connected to the inside of the piston tube, a piston rod is slidably connected inside the piston tube, an elastic element is fixedly provided on the outer wall of the piston rod, and a clamping block is fixedly connected to the end of the piston rod away from the elastic element.

[0012] Preferably, the outer wall of the pressure block is slidably connected to the inside of the fixed frame, the airbag is installed inside the fixed frame, and the outer wall of the air guide tube is fixedly connected to the inside of the fixed frame.

[0013] Preferably, the end of the elastic element away from the piston rod is fixedly disposed inside the piston tube, the outer wall of the clamping block is slidably connected to the inside of the connecting rod, and the outer wall of the clamping block is attached to the outer wall of the printing roller body.

[0015] Preferably, the fixing frame has a groove inside, and the pressure block is slidably connected to the groove.

[0016] Working principle: By turning the handle, the rotating block is rotated to release the limiting fixation between the sliding seat and the base. Then, by pulling the handle, the sliding seat will slide on the base due to the fixing action between the handle and the sliding seat. At the same time, the sliding component will slide on the outer wall of the fixed rod, thereby achieving quick disassembly of the printing roller body. This improves the traditional method of disassembling the screws at both ends before overall disassembly and assembly, and greatly reduces the time cost required to disassemble and replace the printing roller body.

[0017] This invention provides a device for automatically cleaning burnt black residue on the bottom of pots. It has the following beneficial effects: 1. This invention removes the limiting fixation between the sliding seat and the base by rotating the handle to drive the rotating block to rotate. Then, pulling the handle drives the sliding seat to slide on the outer wall of the fixed rod through the sliding component, thereby realizing the disassembly and replacement of the printing roller body. This improves the traditional method of disassembling the printing roller body, which requires first removing the screws at both ends and then disassembling and replacing the entire structure. This significantly reduces the time cost required to replace the printing roller body.

[0018] 2. This invention achieves the effect of automatically removing the printing roller body through the cooperation between the electric slide, motor, adjustment component, pressure block, air bag, air guide pipe and clamping component.

[0019] 3. This invention achieves automatic flattening of the printing roller body when it is removed by meshing transmission between gears and racks, which facilitates the handling and removal of the printing roller body by operators later. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a locking support mechanism for convenient printing roller replacement, including a base 1 and a handle 2. A rotating block 3 is rotatably connected inside the handle 2, and a sliding seat 5 is rotatably connected to the outer wall of the rotating block 3. A handle 4 is fixedly connected to the outer wall of the sliding seat 5. The lower surface of the sliding seat 5 is slidably connected to the upper surface of the base 1. A sliding component 7 is fixedly provided on the outer wall of the sliding seat 5. The sliding component 7 includes a sliding block 71. A fixing rod 8 is slidably connected inside the sliding block 71. The outer wall of the fixing rod 8 is fixedly connected to the outer wall of the base 1. A printing roller body 9 is installed inside the sliding seat 5.

[0024] Specifically, when it is necessary to disassemble the printing roller body 9, first turn the handle 2 to drive the rotating block 3 to rotate, further canceling the limiting fixation between the sliding seat 5 and the base 1. Then pull the handle 4. When the handle 4 moves, through the fixing action of the handle 4 and the sliding seat 5, the sliding seat 5 will slide on the upper surface of the base 1, further driving the sliding component 7 to slide on the outer wall of the fixing rod 8, thereby realizing the quick disassembly of the printing roller body 9. This facilitates the disassembly and replacement of the printing roller body 9 in the future, improving the traditional disassembly of the printing roller body 9, which requires the removal of the screws at both ends and the disassembly and replacement of the entire structure, and greatly reducing the time cost required to replace the printing roller body 9.

[0025] Please see the appendix Figure 1 - Appendix Figure 3The sliding assembly 7 also includes a reinforcing block 72, the outer wall of which is fixedly connected to the outer wall of the sliding seat 5, and the side of the reinforcing block 72 away from the sliding seat 5 is fixedly connected to the outer wall of the sliding block 71; a T-shaped groove 6 is provided inside the base 1, and the sliding seat 5 and the T-shaped groove 6 are slidably connected.

[0026] Specifically, the reinforcing block 72 is used to enhance the stability of the connection between the sliding seat 5 and the sliding block 71, and the T-shaped groove 6 and the rotating block 3 cooperate with each other to lock or unlock the sliding seat 5.

[0027] Please see the appendix Figure 4 - Appendix Figure 6 An electric slide 10 is installed above the printing roller body 9. A motor 11 is fixedly installed on the outer wall of the electric slide 10. An adjustment assembly 12 is fixedly installed on the drive end of the motor 11. The adjustment assembly 12 includes a fixed frame 123. An electric push rod 13 is fixedly installed on the lower surface of the fixed frame 123. A connecting rod 14 is fixedly connected to the drive end of the electric push rod 13. A connecting column 15 is fixedly connected to the outer wall of the connecting rod 14. A pressure block 16 is fixedly connected to the top of the connecting column 15. An air bladder 17 is attached to the lower surface of the pressure block 16. An air guide pipe 18 is fixedly installed inside the air bladder 17. A clamping assembly 19 is fixedly installed at the end of the air guide pipe 18 away from the air bladder 17. The adjustment assembly 12 also includes a lead screw 121. The outer wall of the lead screw 121 is fixedly connected to the drive end of the motor 11. The end of the lead screw 121 away from the motor 11 is rotatably connected to the inside of the electric slide 10. The outer wall of the lead screw 121 is screwed... The printing roller body 9 is rotatably connected to the outer wall of the fixed frame 123 via a threaded block 122. The clamping assembly 19 includes a piston tube 191, with one end of the air guide tube 18 away from the airbag 17 fixedly connected to the inside of the piston tube 191. A piston rod 192 is slidably connected inside the piston tube 191. An elastic element 193 is fixedly provided on the outer wall of the piston rod 192. A clamping block 194 is fixedly connected to the one end of the piston rod 192 away from the elastic element 193. The outer wall of the pressure block 16 is slidably connected to the inside of the fixed frame 123. The airbag 17 is installed inside the fixed frame 123. The outer wall of the air guide tube 18 is fixedly connected to the inside of the fixed frame 123. The one end of the elastic element 193 away from the piston rod 192 is fixedly provided inside the piston tube 191. The outer wall of the clamping block 194 is slidably connected to the inside of the connecting rod 14. The outer wall of the clamping block 194 is attached to the outer wall of the printing roller body 9.

[0028] Specifically, when the sliding seat 5 is pulled outward to remove the printing roller body 9, the motor 11 is first turned on to drive the lead screw 121 to rotate inside the electric slide table 10, which in turn drives the threaded block 122 connected to its outer wall to move. When the threaded block 122 moves, the fixing action between the threaded block 122 and the fixing frame 123 will drive the fixing frame 123 to move, which in turn drives the electric push rod 13 and the connecting rod 14 to move synchronously. When the threaded block 122 drives the electric push rod 13 and the connecting rod 14 to the appropriate position, the electric push rod 13 is opened by external control, which in turn drives the connecting rod 14 to slide downward. When the connecting rod 14 moves, the fixing action between the connecting rod 14 and the connecting column 15 will drive the connecting column 15 to move, which in turn drives the pressure block 16 to slide downward inside the fixing frame 123. While sliding, the airbag 17 is compressed, and the gas generated by the compressed airbag 17 is further transported to the piston rod 192 through the air guide pipe 18. This pushes the piston rod 192 to slide inside the piston tube 191, and stretches the elastic element 193 while sliding. The elastic element 193 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. When the piston rod 192 moves, the clamping block 194 moves due to the fixing action of the piston rod 192 and the clamping block 194, clamping and fixing the printing roller body 9. Thus, when the printing roller body 9 needs to be removed, the printing roller body 9 can be automatically removed through the cooperation between the electric slide table 10, the motor 11, the adjusting component 12, the pressure block 16, the airbag 17, the air guide pipe 18 and the clamping component 19.

[0029] Please see the appendix Figure 6 and attached Figure 7 A gear 20 is fixedly connected to the outer wall of the fixed frame 123. The end of the electric push rod 13 away from the connecting rod 14 is fixedly connected to the lower surface of the fixed frame 123. The tooth end of the gear 20 is meshed with a rack 21, which is fixedly installed on the outer wall of the electric slide table 10. A groove is provided inside the fixed frame 123, and the pressure block 16 is slidably connected to the groove.

[0030] Specifically, when the printing roller body 9 is clamped by the clamping block 194 and moved outward, the fixed frame 123 is moved by the threaded block 122, which in turn drives the gear 20 to move synchronously. After the gear 20 moves a certain distance, it will be driven to rotate through the meshing between the gear 20 and the rack 21. When the gear 20 rotates, it will drive the electric push rod 13 and the connecting rod 14 to rotate synchronously, thereby achieving the effect of automatically flattening the printing roller body 9 when it is taken out, which makes it convenient for the operators to handle and take out the printing roller body 9 later.

[0031] Workflow: When the printing roller body 9 is removed, the motor 11 is started to drive the lead screw 121 to rotate, which in turn drives the threaded block 122 to move. When the threaded block 122 moves, it drives the fixed frame 123, the electric push rod 13 and the connecting rod 14 to move. Then the electric push rod 13 is turned on, which drives the connecting rod 14 to move downward. The connecting column 15 and the pressure block 16 compress the air bag 17, and the gas generated by the compressed air bag 17 is sent into the piston rod 192 through the air guide pipe 18. This pushes the piston rod 192 to slide in the piston tube 191, which in turn drives the clamping block 194 to move and clamp the printing roller body 9, thus achieving the effect of automatically removing the printing roller body 9.

[0032] When the clamping block 194 moves outward after fixing the printing roller body 9, the threaded block 122 drives the fixing frame 123 and gear 20 to move. After the gear 20 moves a certain distance, it will mesh with the rack 21 and rotate, thereby driving the electric push rod 13 and the connecting rod 14 to rotate synchronously, further enabling the printing roller body 9 to automatically rotate and flatten, which facilitates subsequent handling and removal.

[0033] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
