Description

Technical Field

[0001] This utility model relates to the technical field of printing rubber rollers, and in particular to a rubber cutting device for printing rubber rollers. Background Technology

[0002] Printing rollers are key components in printing machinery used to transfer ink, paper, and other media to achieve the printing process. They are typically composed of a metal roller core and an outer layer of elastic rubber. Their core function is to uniformly transfer ink to the surface of substrates such as paper and plastic film through the elastic deformation and friction of the roller surface, while ensuring image clarity and registration accuracy through pressure control.

[0003] A Chinese patent website discloses a rubber cutting and peeling device for printing rubber rollers, publication number CN209141062U. This utility model has a simple structure, novel construction, and reasonable design. The two ends of the iron core of the printing rubber roller to be processed are respectively mounted on the top of the pressure plate at the output end of motor one and the piston rod end of the pressure plate of hydraulic cylinder one. The piston rod driven by hydraulic cylinder one fixes the printing rubber roller between the pressure plates, and motor one drives the printing rubber roller to rotate. Hydraulic cylinder two drives the piston rod to push the connecting blocks on both sides of C-shaped support seat two to slide on the slide rod, thereby adjusting the horizontal position of the cutter at the output end of motor three. Motor two drives the nut seat to move vertically on the screw, thereby causing the nut seat to drive motor three to move vertically, so that the cutter at the output end of motor three cuts and peels the printing rubber roller in the vertical direction, improving the cutting and peeling efficiency of the printing rubber roller and reducing the workload of the operator.

[0004] The solution also has the following problems: when the device cuts the printing roller, the cutter may be damaged or the printing roller may be damaged if the pressure is too high when it gets close to the printing roller because there is no buffer structure. This will affect the processing efficiency and has certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a rubber cutting device for printing rubber rollers. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0023] A rubber cutting device for printing rubber rollers, as shown in the reference. Figure 1 - Figure 4The system includes a base 1, a first base 2 mounted on one top end of the base 1, a first support frame 3 mounted on the top of the first base 2, a first electric telescopic rod 4 mounted on the inner bottom of the first support frame 3, pressure plates 5 symmetrically mounted on the top movable end of the first electric telescopic rod 4 and the inner top of the first support frame 3, a second base 6 mounted on the top end of the base 1 away from the first base 2, a second support frame 7 mounted on the top of the second base 6, a threaded rod 8 mounted between the inner walls of the second support frame 7, a movable block 9 mounted on the outside of the threaded rod 8, a second electric telescopic rod 10 mounted on the outside of the movable block 9, a fixed plate 11 mounted on the movable end of the second electric telescopic rod 10, a support plate 12 mounted on the outside of the fixed plate 11, grooves 1201 symmetrically opened on the outer sides of the support plate 12, adjusting rods 13 symmetrically mounted on the outer sides of the fixed plate 11, sliders 14 mounted on one end of the adjusting rods 13 and inside the grooves 1201, and a cutter 15 mounted on the side of the support plate 12 away from the two grooves 1201.

[0024] Reference Figure 1 - Figure 3 A drive motor 16 is installed on the top of the first support frame 3. The output shaft of the drive motor 16 passes through the first support frame 3 and is connected to one of the pressure plates 5. The drive motor 16 drives the pressure plate 5 to rotate through the output shaft, thereby driving the printing roller clamped between the two pressure plates 5 to rotate synchronously, and achieves cutting in conjunction with the lateral movement of the cutter 15.

[0025] Reference Figure 1 - Figure 3 An adjusting bolt 17 is installed on the outside of the first support frame 3. One end of the adjusting bolt 17 passes through the first support frame 3 and a cleaning brush 18 is installed thereon. The outer ring surface of the adjusting bolt 17 is threadedly connected to the inside of the first support frame 3. By rotating the adjusting bolt 17, the cleaning brush 18 is controlled to move horizontally along the thread direction, adjusting the contact pressure between the cleaning brush 18 and the surface of the printing roller. During the rotation of the roller, residual glue or impurities are removed from the surface, preventing glue from interfering with the accuracy of the cutter 15 during cutting. The top and bottom of the inner side of the first support frame 3 are symmetrically provided with sliding grooves 301. Limiting posts 19 are installed at the top and bottom of the cleaning brush 18 and inside the two sliding grooves 301. The limiting posts 19 cooperate with the sliding grooves 301 to limit the movement trajectory of the cleaning brush 18 to a straight line, preventing the cleaning brush 18 from deflecting when the adjusting bolt 17 is rotated, ensuring that the cleaning brush 18 is always parallel to the axis of the printing roller, and improving the uniformity of cleaning.

[0026] Reference Figure 1 - Figure 3A servo motor 20 is installed on the top of the second support frame 7. The output shaft of the servo motor 20 passes through the second support frame 7 and is connected to one end of the threaded rod 8. The outer ring surface of the threaded rod 8 is threadedly connected to the inside of the movable block 9. The servo motor 20 drives the threaded rod 8 to rotate, causing the movable block 9 to move axially along the threaded rod 8, thereby driving the cutter 15 to achieve height adjustment. The outer side of the movable block 9 is slidably connected to the inner wall of the second support frame 7. The cutter 15, the two sets of pressure plates 5 and the cleaning brush 18 are located on the same axis. The sliding connection between the movable block 9 and the inner wall of the second support frame 7 ensures that the cutter 15 only moves axially along the threaded rod 8, avoiding deviation. The coaxial design ensures that the cutting point of the cutter 15 and the printing roller is always located at the center of the roller, ensuring that the cutting surface is flat and without skewing.

[0027] Reference Figure 1 - Figure 4 Both ends of the adjusting rod 13 are rotatably connected to the outside of the fixed plate 11 and the support plate 12. The outside of the movable block 9 is slidably connected to the inner side wall of the groove 1201. A damper 21 is installed on one end of the movable block 9 and connected to the inner side wall of the groove 1201. The rotatable connection of the adjusting rod 13 allows the support plate 12 to swing slightly during cutting. The damper 21 absorbs the impact force and prevents hard contact from damaging the cutter 15 or the rubber roller. The sliding fit between the movable block 9 and the groove 1201 further enhances the buffering effect. A collection tray 22 is installed on the top of the base 1 and below the two sets of pressure plates 5. The collection tray 22 collects the rubber chips or waste generated during the cutting process and prevents them from falling into the equipment or on the ground, making it easy to clean them up.

[0028] The implementation principle of the rubber cutting device for printing rubber rollers according to this utility model embodiment is as follows: When using the device, the first electric telescopic rod 4 drives the top pressure plate 5 to contact one end of the printing rubber roller, forming a clamping and fixing with the top pressure plate 5. The second electric telescopic rod 10 pushes the cutter 15 to the cutting position. The drive motor 16 drives the pressure plate 5 to rotate through the output shaft, thereby driving the printing rubber roller clamped between the two pressure plates 5 to rotate synchronously. The cutting is achieved by the lateral movement of the cutter 15. The cleaning brush 18 is controlled to move horizontally along the thread direction by rotating the adjusting bolt 17, adjusting the contact pressure between the cleaning brush 18 and the surface of the printing rubber roller. During the rotation of the rubber roller, residual rubber chips or impurities on the surface are removed, avoiding the rubber chips from interfering with the accuracy of the cutter 15 during cutting. The limit post 19 and the slide groove 301 cooperate to limit the movement trajectory of the cleaning brush 18 to a straight line, preventing the cleaning brush 18 from deflecting when the adjusting bolt 17 is rotated, and ensuring that the cleaning brush 18 starts to move in a straight line. The final parallel alignment with the printing roller axis improves cleaning uniformity. The collection tray 22 collects the rubber chips or waste generated during the cutting process, preventing them from scattering inside the equipment or on the ground, facilitating centralized cleaning. The servo motor 20 drives the threaded rod 8 to rotate, causing the movable block 9 to move axially along the threaded rod 8, thereby driving the cutter 15 to achieve height adjustment. The sliding connection between the movable block 9 and the inner wall of the second support frame 7 ensures that the cutter 15 moves only axially along the threaded rod 8, avoiding deviation. The coaxial design ensures that the cutting point of the cutter 15 and the printing roller is always located at the center of the roller, guaranteeing a flat and non-skewed cutting surface. The rotational connection of the adjusting rod 13 allows the support plate 12 to swing slightly during cutting. The damper 21 absorbs the impact force, preventing hard contact that could damage the cutter 15 or the roller. The sliding fit between the movable block 9 and the groove 1201 further enhances the buffering effect, making operation convenient and more practical. The external spiral opening angle of the threaded rod 8 and the adjusting bolt 17 is 20 degrees, and the thread self-locking condition meets the following formula: self-locking condition = friction coefficient * tan (spiral angle) ≥ 1.
