Description

Technical Field

[0001] The present application relates to the technical field of laser platemaking, and in particular to a laser platemaking device. Background Art

[0002] In recent years, laser platemaking technology has become a more advanced platemaking method. Its main working principle is: use laser to act on the pre-coated protective layer (mainly photosensitive adhesive, etc.) on the surface of the plate roller according to the trajectory of the printing plate pattern. The protective layer falls off and the part of the plate roller surface exposed is the printing plate pattern. The plate roller is then corroded, cleaned, etc. to finally form the printing plate pattern.

[0003] In the prior art, the laser platemaking equipment includes a machine platform and a laser engraving assembly arranged on the machine platform. A clamping piece for clamping a plate roller is arranged on the machine platform. After the surface of the plate roller is coated with a protective layer, the two ends of the plate roller are clamped and fixed on the machine platform by the clamping piece, and then a laser plate pattern is printed on it by the laser engraving assembly. However, when the plate roller is docked with the clamping piece, it is necessary to ensure that a certain degree of alignment is maintained between the plate roller and the clamping piece so that the clamping piece can clamp it. For large-sized plate rollers, such plate rollers have a certain weight, which makes it time-consuming and laborious to adjust the position of the plate roller, increases the difficulty of installation between the plate roller and the machine platform, and thus reduces the work efficiency of platemaking, so further improvement is needed. Summary of the invention

[0004] In order to improve the installation convenience between the plate roller and the machine platform, the present application provides a laser platemaking device.

[0005] The laser plate-making equipment provided in this application adopts the following technical solution: A laser platemaking device comprises a machine platform and a laser engraving assembly arranged on the machine platform, wherein two sliding seats are slidably installed on the machine platform, a plate roller is arranged between the two sliding seats, and side walls of the two sliding seats close to each other are provided with a three-jaw chuck for clamping the plate roller; two lifting seats are slidably installed on the machine platform, the two lifting seats are respectively used to support the two ends of the plate roller, and the sliding seat is provided with a lifting assembly for driving the lifting seat to rise and fall.

[0006] By adopting the above technical solution, through the setting of the lifting seat and the lifting assembly, when the plate roller is installed, the two ends of the plate roller are overlapped on the two lifting seats respectively, and the lifting seat is driven to lift by the lifting assembly, so that the plate roller is lifted to align with the three-claw chuck of the sliding seat, and then the two sliding seats are driven to approach each other, and the plate roller is clamped and limited by the three-claw chuck. Then the lifting seat is driven to move downward to make the plate roller detach from the lifting seat, and finally the plate roller is laser-printed with a plate pattern through the laser engraving assembly. The setting of the lifting seat can facilitate the alignment between the plate roller and the three-claw chuck, thereby facilitating the disassembly and assembly of the plate roller and improving the work efficiency of plate making.

[0007] Optionally, the three-jaw chuck has a clamping channel for the plate roller to extend into, and the lifting assembly includes a guide block and a push rod, the guide block is arranged at the bottom of the lifting seat, one end of the push rod is connected to the sliding seat, and the free end of the push rod abuts against the bottom wall of the guide block; the bottom wall of the guide block forms a continuous first horizontal plane, a second horizontal plane and a third horizontal plane in sequence from a side close to the sliding seat to a side away from the sliding seat, the first horizontal plane and the third horizontal plane are at the same height, and the first horizontal plane is higher than the height of the second horizontal plane, and when the free end of the push rod is displaced to the second horizontal plane, the lifting seat is lifted and drives the plate roller to be lifted to be flush with the clamping channel.

[0008] By adopting the above technical scheme, through the arrangement of the guide block and the push rod, under normal circumstances, the sliding seat forces the push rod to move to the first horizontal plane of the guide block, overlaps the two ends of the plate roller on the two lifting seats, drives the sliding seat to move toward the plate roller, and the sliding seat can drive the free end of the push rod to move from the first horizontal plane to the second horizontal plane. During this process, the push rod can push the lifting seat, forcing the lifting seat to lift and force the plate roller to be lifted to be flush with the clamping channel; continue to displace the sliding seat to insert the plate roller into the clamping channel (at this time the free end of the push rod is still located at the second horizontal plane); continue to displace the sliding seat to transfer the free end of the push rod from the second horizontal plane to the third horizontal plane. During this process, the lifting seat can move downward to disengage from the plate roller, so that the plate roller is transferred from the lifting seat to the sliding seat. During disassembly, the push rod is forced to move from the third horizontal plane to the second horizontal plane, so that the lifting seat can be lifted again to dock with the plate roller. After docking, the push rod is forced to move from the second horizontal plane to the first horizontal plane, so that the lifting seat can be driven downward, thereby lowering the plate roller, greatly improving the convenience of disassembly and assembly of the plate roller.

[0010] By adopting the above technical solution, through the arrangement of the first guide surface and the second guide surface, the first horizontal surface, the second horizontal surface and the third horizontal surface can form a continuous surface, so that when the push rod moves along the bottom wall of the guide block, the lifting seat can be driven to move up and down.

[0011] Optionally, a support plate is installed on the top wall of the lifting seat, and a support groove is opened on the top wall of the support plate for the plate roller to be embedded, and the lifting seat supports the plate roller through the support plate; the support plate is provided with a centering component, and when the free end of the push rod is displaced to the second horizontal plane, the centering component is used to force the central axis of the plate roller to coincide with the central axis of the clamping channel.

[0012] By adopting the above-mentioned technical scheme, through the arrangement of the support plate and the centering assembly, after the plate roller is embedded in the support groove, the support plate supports it; when the free end of the push rod is displaced to the second horizontal plane (that is, the plate roller is lifted to be flush with the clamping channel), the centering assembly is used to force the central axis of the plate roller to coincide with the central axis of the clamping channel, so as to improve the alignment accuracy between the plate roller and the clamping channel, so as to facilitate the three-jaw chuck to clamp and fix it, thereby improving the convenience of installation.

[0013] Optionally, the centering assembly includes a centering block and a limiting bolt, the centering block is inserted in the supporting groove, the top wall of the centering block is provided with a centering groove, the inner wall of the centering groove is in contact with the peripheral wall of the plate roller; the side wall of the support plate is provided with a first limiting hole connected to the supporting groove, the side wall of the centering block is provided with a second limiting hole, the limiting bolt is sequentially passed through the first limiting hole and the second limiting hole and is threadedly connected to the second limiting hole, and the centering block is detachably mounted on the support plate by the limiting bolt.

[0014] By adopting the above technical scheme, through the setting of the positioning block and the limiting bolt, the centering groove of the centering block is provided for the plate roller to be embedded to limit the axis of the plate roller, so that when the lifting seat is lifted, the central axis of the plate roller and the central axis of the clamping channel can remain coincident, so as to facilitate the clamping and fixing of the plate roller by the three-jaw chuck; when the diameter of the plate roller changes, the centering block can be disassembled by the limiting bolt, and the centering block with different arc centering grooves can be replaced to adapt to the diameter change of the plate roller, thereby greatly improving the adaptability of the overall structure.

[0015] Optionally, the centering component includes a pushing bar, a swinging bar, a linkage and a driving member. The pushing bar is slidably installed on the support plate and can be lifted and lowered. Two swinging bars are provided and are symmetrically distributed on both sides of the pushing bar. Each swinging bar is hinged to the support plate. A centering area for the plate roller to be embedded is formed between the upper end of the pushing bar and the upper ends of the two swinging bars; the linkage is provided between the pushing bar and the two swinging bars, and the linkage is used to drive the pushing bar and the two swinging bars to move synchronously to expand or reduce the centering area; the driving member is provided between the lifting seat and the machine platform, and when the lifting seat is lifted, the driving member drives the pushing bar to lift to reduce the centering area.

[0016] By adopting the above technical scheme, through the arrangement of the push bar, the swing bar, the linkage and the driving member, one end of the plate roller is placed in the support groove and then embedded in the centering area, driving the lifting seat to lift. At this time, the driving member can drive the push bar to lift. Under the action of the linkage, the two swing bars can swing towards the centering area at the same time, thereby reducing the centering area, that is, forcing the upper end of the push bar and the upper ends of the two swing bars to abut against the peripheral wall of the plate roller; the two swing bars swing at the same time to quickly position the plate roller, so that the position of the plate roller is adjusted to the center position of the centering area, so that when the lifting action of the lifting seat is completed, the central axis of the plate roller can coincide with the central axis of the clamping channel, thereby improving the convenience of the plate roller centering operation.

[0017] Optionally, the linkage member includes a first abutment wheel and a tension spring, two first abutment wheels are provided and are arranged corresponding to the two swing bars, and each of the first abutment wheels is rotatably connected to the lower end of the corresponding swing bar; abutment blocks are provided on both sides of the pushing bar, and the two abutment blocks are arranged corresponding to the two swing bars, and each of the abutment blocks has an abutment surface; the two ends of the tension spring are respectively connected to the two swing bars, and the tension spring forces the first abutment wheels of the two swing bars to abut against the abutment surfaces of their respective corresponding abutment blocks, and when the pushing bar is lifted relative to the support plate, the upper ends of the two swing bars approach each other to reduce the centering area, and when the pushing bar is lowered relative to the support plate, the upper ends of the two swing bars move away from each other to expand the centering area.

[0018] By adopting the above-mentioned technical scheme, through the arrangement of the first abutment wheel and the tension spring, the action of the tension spring enables the first abutment wheel to remain in abutment with the abutment surface of the corresponding abutment block, so that when the push bar is lifted, the push bar can push the first abutment wheel through the abutment surface, forcing the two swing bars to swing at the same time, so as to realize the synchronous action between the push bar and the two swing bars, and achieve the effect of expanding or reducing the centering area to position the central axis of the plate roller.

[0019] Optionally, the upper end of the push bar and the upper ends of the two swing bars are rotatably connected to second abutment wheels, and when the centering area is reduced, each of the second abutment wheels abuts against the peripheral wall of the plate roller.

[0020] By adopting the above-mentioned technical solution and setting the second abutment wheel, when the push bar is lifted to drive the upper ends of the two swing bars to swing towards the centering area at the same time, the swing bar abuts and pushes the plate roller through the second abutment wheel, thereby reducing the friction between the swing bar and the plate roller, so that the swing bar can more easily and quickly correct the deviation of the plate roller and keep the central axis of the plate roller aligned with the central axis of the clamping channel.

[0021] Optionally, the driving member includes a rotating gear, a first rack and a second rack, the rotating gear is rotatably connected to the lifting seat; the first rack and the second rack are both vertically arranged, the first rack is connected to the pushing bar, and the second rack is connected to the machine table, and the first rack and the rotating gear, as well as the second rack and the rotating gear are meshed for transmission; when the lifting seat is lifted, the first rack is lifted relative to the support plate, and when the lifting seat is lowered, the first rack is lowered relative to the support plate.

[0022] By adopting the above technical solution, through the arrangement of the rotating gear, the first rack and the second rack, when the lifting seat is lifted, the first rack can be lifted relative to the support plate to force the push bar to be lifted relative to the support plate, thereby reducing the centering area to quickly position the central axis of the plate roller; when the lifting seat is lowered, the first rack can drive the push bar to descend relative to the support plate, forcing the swing bar to swing in the opposite direction and separate from the peripheral wall of the plate roller, thereby allowing the lifting seat to descend, thereby improving the operational convenience of the overall structure.

[0023] Optionally, the side wall of the push bar is provided with an adjustment groove, and both ends of the adjustment groove are extended along the height direction; the side wall of the first rack is provided with an adjustment block slidably connected to the adjustment groove, and the first rack is slidably installed on the push bar through the adjustment block; the push bar is provided with an adjustment bolt, and the side wall of the push bar is provided with a plurality of adjustment holes connected to the adjustment groove, and the plurality of adjustment holes are arranged at intervals along the height direction; the adjustment bolt is passed through the adjustment hole and threadedly connected to the adjustment hole, one end of the adjustment bolt extends into the adjustment groove, and the surrounding wall of the adjusting bolt is used to abut against the top wall of the adjustment block to limit the maximum displacement of the adjustment block in the adjustment groove.

[0024] By adopting the above technical solution, through the setting of the adjustment block and the adjustment bolt, when the diameter of the plate roller changes, by controlling the height of the adjustment bolt (i.e., controlling the distance between the adjustment bolt and the adjustment block), the maximum displacement of the adjustment block in the adjustment slot is limited. If there is a gap between the adjustment block and the adjustment bolt in the initial state (the lifting seat is not lifted), the lifting of the lifting seat drives the first rack to lift, and the adjustment block can slide for a distance in the adjustment slot (the first rack cannot drive the push bar to lift at this time), thereby controlling the swing amplitude of the swing bar. In other words, the lifting distance of the lifting seat is fixed. When the diameter of the plate roller changes, the maximum displacement of the adjustment block is controlled by the adjustment bolt, thereby controlling the final swing amplitude of the swing bar to adapt to the diameter change of the plate roller and improve the adaptability of the overall structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the lifting seat and the lifting assembly, when installing the plate roller, the two ends of the plate roller are overlapped on the two lifting seats respectively, and the lifting seat is driven to lift through the lifting assembly, so that the plate roller is lifted to align with the three-claw chuck of the sliding seat, and then the two sliding seats are driven to approach each other, and the plate roller is clamped and limited by the three-claw chuck. Then the lifting seat is driven down to make the plate roller separate from the lifting seat, and finally the plate roller is laser-printed with the plate pattern through the laser engraving assembly. The setting of the lifting seat can facilitate the alignment between the plate roller and the three-claw chuck, thereby facilitating the disassembly and assembly of the plate roller and improving the work efficiency of plate making; 2. Through the arrangement of the push bar, the swing bar, the linkage and the driving member, one end of the plate roller is placed in the support groove and then embedded in the centering area, driving the lifting seat to lift. At this time, the driving member can drive the push bar to lift. Under the action of the linkage, the two swing bars can swing towards the centering area at the same time, thereby reducing the centering area, that is, forcing the upper end of the push bar and the upper ends of the two swing bars to abut against the peripheral wall of the plate roller; the two swing bars swing at the same time to quickly position the plate roller, so that the position of the plate roller is adjusted to the center position of the centering area, so that when the lifting seat is lifted, the central axis of the plate roller can coincide with the central axis of the clamping channel, thereby improving the convenience of the plate roller centering operation; 3. Through the setting of the adjustment block and the adjustment bolt, when the diameter of the plate roller changes, by controlling the height of the adjustment bolt (i.e., controlling the distance between the adjustment bolt and the adjustment block), the maximum displacement of the adjustment block in the adjustment slot is limited. If there is a gap between the adjustment block and the adjustment bolt in the initial state (the lifting seat is not lifted), the lifting of the lifting seat drives the first rack to lift, and the adjustment block can slide for a distance in the adjustment slot (the first rack cannot drive the push bar to lift at this time), thereby controlling the swing amplitude of the swing bar. In other words, the lifting distance of the lifting seat is fixed. When the diameter of the plate roller changes, the maximum displacement of the adjustment block is controlled by the adjustment bolt, thereby controlling the final swing amplitude of the swing bar to adapt to the diameter change of the plate roller and improve the adaptability of the overall structure.

A lifting assembly 6 is provided between each sliding seat 3 and the corresponding lifting seat 5, and the lifting assembly 6 is used to drive the lifting seat 5 to move up and down; in this embodiment, the lifting assembly 6 includes a guide block 61 and a push rod 62, and the bottom wall of the lifting seat 5 is provided with a first mounting groove 52, and the guide block 61 is fixedly installed on the inner wall of the first mounting groove 52, and the sliding seat 3 is installed with a mounting bracket near the side wall of the corresponding lifting seat 5 32, the mounting bracket 32 ​​is connected to the sliding seat 5 by bolts, the push rod 62 is vertically arranged, the lower end of the push rod 62 is fixedly installed on the end of the mounting bracket 32 ​​away from the sliding seat 3, the free end of the push rod 62 (that is, the upper end of the push rod 62) is rotatably connected to the third abutment wheel 621, the peripheral wall of the third abutment wheel 621 abuts against the bottom wall of the guide block 61, and the free end of the push rod 62 abuts against the bottom wall of the guide block 61 through the third abutment wheel 621 to support the guide block 61.

[0035] Reference Figure 4The bottom wall of the guide block 61 forms a continuous first horizontal plane 611, a second horizontal plane 612 and a third horizontal plane 613 in sequence from the side close to the corresponding sliding seat 3 to the side away from the corresponding sliding seat 3; the guide block 61 includes a first guide portion 614 and a second guide portion 615 that are integrally formed, the first guide portion 614 is fixedly installed on the inner wall of the first mounting groove 52, and the second guide portion 615 is fixedly installed on the bottom wall of the first guide portion 614; in this embodiment, the first horizontal plane 611 and the third horizontal plane 613 are both located on the bottom wall of the first guide portion 614 (that is, the first horizontal plane 611 and the third horizontal plane 613 are located at the same height), the first horizontal plane 611 and the third horizontal plane 613 are symmetrically distributed on both sides of the second guide portion 615, and the second horizontal plane 612 is located on the bottom wall of the second guide portion 615 (that is, the first horizontal plane 611 and the third horizontal plane 613 are both higher than the height of the second horizontal plane 612).

[0036] The width of the second guide portion 615 decreases gradually from top to bottom and forms a first guide surface 616 and a second guide surface 617 respectively. The two sides of the first guide surface 616 are respectively connected to the first horizontal surface 611 and the second horizontal surface 612, and the two sides of the second guide surface 617 are respectively connected to the second horizontal surface 612 and the third horizontal surface 613; when the third abutting wheel 621 of the push rod 62 abuts against the second horizontal surface 612, the lifting seat 5 is lifted and drives the plate roller 4 to be lifted to be flush with the clamping channel 311.

[0037] Reference Figure 2 , Figure 3 The support plate 51 is provided with a centering assembly 7. When the third abutting wheel 621 of the push rod 62 abuts against the second horizontal plane 612, the centering assembly 7 is used to force the central axis of the plate roller 4 to coincide with the central axis of the clamping channel 311. In this embodiment, the centering assembly 7 includes a centering block 71 and a limiting bolt 72. The centering block 71 is inserted into the support groove 511. The top wall of the centering block 71 is provided with a centering groove 711, which is a circular arc groove for fitting against the peripheral wall of the plate roller 4.

[0038] Reference Figure 3 A first limiting hole connected to the supporting groove 511 is formed on the side wall of the supporting plate 51, and a second limiting hole is formed on the side wall of the centering block 71.

[0039] It should be noted that the setting of the centering component 7 is for the need to perform laser engraving operations on plate rollers 4 of different sizes. In actual processing operations, if the workshop only needs to perform laser engraving operations on a plate roller 4 of a fixed size, there is no need to set the centering component 7, and it is only necessary to set the shape of the support groove 511 to an arc groove that is suitable for the plate roller 4.

[0040] The implementation principle of the embodiment 1 of the present application is as follows: before the plate roller 4 is installed, the two sliding seats 3 are driven to move away from each other so that the third abutting wheel 621 of the push rod 62 is moved to the first horizontal plane 611, and then the two ends of the plate roller 4 are respectively overlapped in the centering grooves 711 of the centering blocks 71 corresponding to the two lifting seats 5, and then the sliding seat 3 is driven to move closer to the plate roller 4, and the sliding seat 3 can drive the third abutting wheel 621 of the push rod 62 to move from the first horizontal plane 611 to the second horizontal plane 612. , forcing the plate roller 4 to be lifted up to be flush with the clamping channel 311; continue to displace the sliding seat 3, so that the plate roller 4 is inserted into the clamping channel 311 (at this time, the third abutment wheel 621 of the push rod 62 is still located at the second horizontal plane 612); continue to displace the sliding seat 3, so that the third abutment wheel 621 of the push rod 62 is transferred from the second horizontal plane 612 to the third horizontal plane 613. During this process, the lifting seat 5 can move downward to disengage from the plate roller 4, so that the plate roller 4 is transferred from the lifting seat 5 to the sliding seat 3.

[0041] During disassembly, the clamping force of the three-jaw chuck 31 on the plate roller 4 is released to force the third abutment wheel 621 of the push rod 62 to move from the third horizontal plane 613 to the second horizontal plane 612, so that the lifting seat 5 can be lifted again to dock with the plate roller 4. After docking, the push rod 62 is forced to move from the second horizontal plane 612 to the first horizontal plane 611, so that the lifting seat 5 can be driven to move downward, thereby lowering the plate roller 4, which greatly improves the convenience of disassembly and assembly of the plate roller 4 and improves the work efficiency of plate making.

[0042] The centering groove 711 of the centering block 71 is for the plate roller 4 to be embedded in, so as to limit the axis of the plate roller 4, so that when the lifting seat 5 is lifted, the central axis of the plate roller 4 and the central axis of the clamping channel 311 can remain coincident, so as to facilitate the three-jaw chuck 31 to clamp and fix the plate roller 4; when the diameter of the plate roller 4 changes, the centering block 71 can be disassembled by the limiting bolt 72, and the centering block 71 with different arc centering grooves 711 can be replaced to adapt to the diameter change of the plate roller 4, thereby greatly improving the adaptability of the overall structure.

[0043] Embodiment 2: The embodiment of the present application discloses a laser plate-making device.

[0044] Reference Figure 5 The difference between the laser plate-making device disclosed in the embodiment of the present application and the embodiment 1 is that: In this embodiment, the centering component 7 includes a pushing bar 73, a swinging bar 74, a linkage part and a driving part. The pushing bar 73 is vertically arranged, and the pushing bar 73 is slidably installed on the side wall of the support plate 51 close to the sliding seat 3 and can be raised and lowered. Two swinging bars 74 are provided and symmetrically distributed on both sides of the pushing bar 73. Each swinging bar 74 is hinged to the side wall of the support plate 51 close to the sliding seat 3. A centering area 75 for the plate roller 4 to be embedded is formed between the upper end of the pushing bar 73 and the upper ends of the two swinging bars 74.

[0046] Reference Figure 5 , Figure 6The driving member is arranged between the lifting seat 5 and the machine platform 1. When the lifting seat 5 is lifted, the driving member drives the push bar 73 to lift to reduce the centering area 75; the driving member includes a rotating gear 76, a first rack 77 and a second rack 78. The top wall of the lifting seat 5 is provided with a second mounting groove 53 connected to the first mounting groove 52. The rotating gear 76 is rotatably connected to the inner wall of the second mounting groove 53; the first rack 77 and the second rack 78 are both arranged vertically. In this embodiment, the first rack 77 is slidably installed on the inner wall of the second mounting groove 53.

The lower end of the second rack 78 extends out of the second mounting groove 53 and is fixedly connected to the bottom wall of the processing station 11 of the machine table 1, and the other end extends into the second mounting groove 53. The first rack 77 and the rotating gear 76, and the second rack 78 and the rotating gear 76 are all meshed and transmitted; when the lifting seat 5 is lifted, the first rack 77 is lifted relative to the support plate 51, and when the lifting seat 5 is lowered, the first rack 77 is lowered relative to the support plate 51.

[0047] Reference Figure 5 It should be noted that, in the present embodiment, there are two guide blocks 61, which are arranged side by side and a avoidance space 54 for avoiding the second rack 78 is formed between the two guide blocks 61, and the number of the push rods 62 is arranged corresponding to the number of the guide blocks 61; with such a design, on the one hand, the avoidance space 54 provides an installation space for the installation of the second rack 78, and on the other hand, by providing two guide blocks 61 and two push rods 62, the supporting effect of the push rods 62 on the lifting seat 5 can be improved.

[0048] Reference Figure 7 In this embodiment, the side wall of the push bar 73 close to the side wall of the first rack 77 is provided with an adjustment groove 733, and the two ends of the adjustment groove 733 are extended in the height direction. The side wall of the first rack 77 is fixedly installed with an adjustment block 771, and the adjustment block 771 is slidably installed in the adjustment groove 733. The first rack 77 is slidably installed on the push bar 73 through the adjustment block 771; the side wall of the push bar 73 away from the first rack 77 is provided with a plurality of adjustment holes 735 connected to the adjustment groove 733, and the plurality of adjustment holes 735 are spaced apart in the height direction. The push bar 73 is arranged in an alternate arrangement, and a connecting groove is provided on the side wall away from the first rack 77. Both ends of the connecting groove are extended along the height direction. The connecting groove connects all the adjustment holes 735. The push bar 73 is provided with an adjusting bolt 734. The adjusting bolt 734 is passed through the adjusting hole 735 and is threadedly connected with the adjusting hole 735. One end of the adjusting bolt 734 extends into the adjusting groove 733. The surrounding wall of the adjusting bolt 734 is used to abut the top wall of the adjusting block 771 to limit the maximum displacement of the adjusting block 771 in the adjusting groove 733.

[0049] The implementation principle of Example 2 of the present application is as follows: one end of the plate roller 4 is placed in the supporting groove 511 and then embedded in the centering area 75, driving the lifting seat 5 to lift. During the lifting process of the lifting seat 5, under the meshing of the rotating gear 76, the first rack 77 and the second rack 78, the pushing bar 73 can be lifted relative to the supporting plate 51, so that the two swinging bars 74 can swing towards the centering area 75 at the same time, thereby reducing the centering area 75, that is, forcing the upper end of the pushing bar 73 and the upper ends of the two swinging bars 74 to abut against the peripheral wall of the plate roller 4; the two swinging bars 74 swing at the same time to quickly position the plate roller 4, so that the position of the plate roller 4 is adjusted to the center position of the centering area 75, so that when the lifting action of the lifting seat 5 is completed, the central axis of the plate roller 4 can coincide with the central axis of the clamping channel 311, thereby improving the convenience of the centering operation of the plate roller 4.

[0050] When the diameter of the plate roller 4 changes, the maximum displacement of the adjusting block 771 in the adjusting slot 733 is limited by controlling the height of the adjusting bolt 734 (i.e., controlling the distance between the adjusting bolt 734 and the adjusting block 771). If there is a gap between the adjusting block 771 and the adjusting bolt 734 in the initial state (the lifting seat 5 is not lifted), the lifting seat 5 drives the first rack 77 to lift, and the adjusting block 771 can slide for a distance in the adjusting slot 733 (the first rack 77 cannot drive the push bar 73 to lift), thereby controlling the swing amplitude of the swing bar 74. In other words, the lifting distance of the lifting seat 5 is fixed. When the diameter of the plate roller 4 changes, the maximum displacement of the adjusting block 771 is controlled by adjusting the bolt 734, thereby controlling the final lifting distance of the push bar 73 and the final swing amplitude of the swing bar 74 (i.e., controlling the size of the centering area 75), so as to adapt to the diameter change of the plate roller 4 and improve the adaptability of the overall structure.

[0051] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
