[0005] This utility model provides a quick-change tooling for printing plate rollers, specifically including: a tooling frame; the tooling frame is placed on the ground, a first hydraulic cylinder for adjusting the height of the tooling frame is installed on the tooling frame, an adjustment part is installed on the tooling frame, the adjustment part consists of a guide rod, a base block and a second hydraulic cylinder, two guide rods are welded to the left end face of the tooling frame, a base block slides on the two guide rods, and a second hydraulic cylinder is fixed on the tooling frame, with the extended end of the second hydraulic cylinder fixed to the base block.

[0006] Furthermore, a replacement part is installed on the base block. The replacement part consists of a rotating shaft, a sliding seat, a worm gear, a worm, a first motor, a clamping seat, a first adjusting rod, a second motor, a clamping block, a second adjusting rod, and a third motor. A rotating shaft rotates on the base block, and a sliding seat is welded to one end of the rotating shaft. A worm gear is welded to the rotating shaft.

[0007] Furthermore, a worm gear rotates on the base block, meshing with a worm wheel, and a first motor is fixed on the base block, with the output shaft of the first motor fixed on the worm gear.

[0008] Furthermore, two clamping seats slide symmetrically on the sliding seat, and a first adjusting rod rotates on the sliding seat. The left and right ends of the first adjusting rod are threaded to the two sliding seats respectively, and the thread directions of the left and right ends of the first adjusting rod are opposite. A second motor is fixed on the sliding seat, and the output shaft of the second motor is fixed on the first adjusting rod.

[0009] Furthermore, each of the clamping seats has two clamping blocks that slide symmetrically, and each clamping seat has a second adjusting rod that rotates.

[0011] Furthermore, all four mounting rods are cylindrical rod-shaped structures, and the upper end of each mounting rod is polished, resulting in an arc-shaped upper end for all four mounting rods.

[0012] This utility model provides a quick-change tooling for printing plate rollers, which has the following beneficial effects:

[0013] This application allows for convenient adjustment of the overall height of the tooling via a first hydraulic cylinder on the tooling frame. In conjunction with a second hydraulic cylinder in the adjustment section, the base block is driven to slide along the guide rod, enabling flexible adjustment of the left and right positions of the printing roller.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 5 :

[0028] This utility model proposes a quick-change fixture for printing plate rollers, comprising: a fixture frame 1; the fixture frame 1 is placed on the ground, and a first hydraulic cylinder for adjusting the height of the fixture frame 1 is installed on the fixture frame 1; an adjustment part 2 is installed on the fixture frame 1, the adjustment part 2 is composed of guide rods 201, a base block 202, and a second hydraulic cylinder 203; two guide rods 201 are welded to the left end face of the fixture frame 1, and the base block 202 slides on the two guide rods 201; the second hydraulic cylinder 203 is fixed on the fixture frame 1, and the extended end of the second hydraulic cylinder 203 is fixed to the base block 202; when adjusting the left and right position of the printing plate roller, the second hydraulic cylinder 203 is driven to extend and retract; when adjusting the height of the printing plate roller, the two first electric cylinders are driven to extend and retract.

[0029] The base block 202 is equipped with a replacement part 3, which consists of a rotating shaft 301, a sliding seat 302, a worm gear 303, a worm 304, a first motor 305, a clamping seat 306, a first adjusting rod 307, a second motor 308, a clamping block 309, a second adjusting rod 310, and a third motor 311. The rotating shaft 301 rotates on the base block 202, and the sliding seat 302 is welded to one lower end of the rotating shaft 301. The worm gear 303 is welded to the rotating shaft 301.

[0030] The base block 202 has a worm gear 304 that rotates on it and meshes with a worm wheel 303. A first motor 305 is fixed on the base block 202, and the output shaft of the first motor 305 is fixed on the worm gear 304. When adjusting the direction of the printing roller, the first motor 305 is driven to rotate, and the first motor 305 drives the worm gear 304 to rotate. Under the meshing transmission of the worm gear 304 and the worm wheel 303, the direction of the printing roller can be rotated, which improves the convenience of the printing roller installation.

[0031] The sliding seat 302 has two symmetrically sliding clamping seats 306. A first adjusting rod 307 is rotatably mounted on the sliding seat 302. The left and right ends of the first adjusting rod 307 are threaded to the two clamping seats 306 respectively. The thread directions of the left and right ends of the first adjusting rod 307 are opposite. A second motor 308 is fixed on the sliding seat 302. The output shaft of the second motor 308 is fixed to the first adjusting rod 307. When adapting to different lengths of printing rollers, the second motor 308 rotates, which drives the first adjusting rod 307 to rotate. Under the threaded drive of the first adjusting rod 307, the distance between the two clamping seats 306 can be adjusted, thereby adapting to printing rollers of different lengths.

[0032] Each clamping seat 306 has two symmetrically sliding clamping blocks 309, and each clamping seat 306 has a rotating second adjusting rod 310. The front and rear ends of the second adjusting rod 310 are threaded to the two clamping seats 306 respectively, and the thread directions of the front and rear ends of the second adjusting rod 310 are opposite. Each clamping seat 306 has a fixed third motor 311, and the output shafts of the two third motors 311 are fixed to the two second adjusting rods 310 respectively. When clamping the printing roller, the clamping blocks 309 are placed on the left and right sides of the printing roller rotation shaft, driving the two third motors 311 to rotate. The two third motors 311 drive the two second adjusting rods 310 to rotate. Under the threaded drive of the second adjusting rods 310, the printing roller can be quickly clamped, improving the replacement efficiency.

[0033] The tooling frame 1 has four mounting rods 101 symmetrically welded to its upper end face. Each mounting rod 101 is fitted with a counterweight 102, which improves the stability of the tooling frame 1 when changing the printing roller.

[0034] Example 2, based on Example 1, such as Figures 1 to 5 As shown, all four mounting rods 101 are cylindrical rod-shaped structures. The upper end of each mounting rod 101 is polished. After polishing, the upper end of all four mounting rods 101 is an arc-shaped structure. When the counterweight 102 is fitted onto the mounting rod 101, the arc-shaped part can improve the installation efficiency of the counterweight 102.

[0035] The working principle of this embodiment is as follows: When using this printing plate roller to quickly change the tooling, firstly, counterweights 102 are fitted onto the four mounting rods 101 on the upper end face of the tooling frame 1. Since the four mounting rods 101 are all cylindrical rod-shaped structures and one end is polished into an arc shape, the counterweights 102 can be installed quickly under the guidance of the arc shape, thereby improving the stability of the tooling frame 1. Next, according to the length of the plate roller to be replaced, the second motor 308 is driven to rotate. The second motor 308 drives the first adjusting rod 307 on the sliding seat 302 to rotate. Since the threads at the left and right ends of the first adjusting rod 307 are opposite and are respectively threaded onto the two clamping seats 306, the distance between the two clamping seats 306 is adjusted under the thread drive to adapt to the length of the plate roller. Then, the clamping block 309 is placed on the left and right sides of the plate roller rotation shaft, and the two third motors 311 are driven to rotate. The third motors 311 drive the second adjusting rod 307 on the clamping seat 306 to rotate. When the entire rod 310 rotates, the threads at the front and rear ends of the second adjusting rod 310 are opposite in direction and are respectively threaded onto the two clamping blocks 309. Under the drive of the threads, the two clamping blocks 309 quickly clamp the printing roller. If the direction of the printing roller needs to be adjusted, the first motor 305 is driven to rotate. The first motor 305 drives the worm gear 304 on the base block 202 to rotate. The worm gear 304 meshes with the worm wheel 303 on the rotating shaft 301, driving the rotating shaft 301 and the sliding seat 302 welded below to rotate, thereby realizing the adjustment of the direction of the printing roller. If the left and right position of the printing roller needs to be adjusted, the second hydraulic cylinder 203 on the tooling frame 1 is driven to extend and retract. If the height of the printing roller needs to be adjusted, the two first hydraulic cylinders are driven to extend and retract. The base block 202, which is fixed at the extended end of the second hydraulic cylinder 203, slides along the two guide rods 201 welded to the left end face of the tooling frame 1, thereby driving the printing roller to complete the left and right position adjustment and completing the printing roller replacement operation.
