Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to a printing press that facilitates the disassembly and assembly of printing rollers. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms for plate mounting, inking, impression, and paper feeding. The process involves creating a printing plate from the text and images to be printed, then manually or by the printing press applying ink to the areas of the plate containing the text and images. Printing rollers are used during the printing process.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, after prolonged use, most existing printing presses sometimes experience aging of the printing rollers, leading to a reduction in the rubber surface area and consequently a decrease in the transfer performance of ink and dampening solution, necessitating replacement. However, the printing rollers in most existing printing presses are fixed with screws, making disassembly and replacement cumbersome. Furthermore, it is difficult to adjust the height and position of the printing rollers according to different usage conditions, thus reducing the applicability of the printing press. Therefore, those skilled in the art have provided a printing press that facilitates the disassembly and assembly of the printing rollers to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a printing press that facilitates the assembly and disassembly of printing rollers. By opening two movable slots on the upper surface of the base plate, an adjustment plate with a fixing mechanism can be placed on the upper end of the movable slots, thereby adjusting the position of the printing roller body between the two fixing mechanisms. The fixing mechanism can fix the printing roller body while also adjusting and fixing its height.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A printing machine that facilitates the assembly and disassembly of printing rollers includes a base plate. A printing plate is fixedly mounted at the midpoint of the upper surface of the base plate. Movable grooves are formed at the midpoints of the front and rear ends of the upper surface of the base plate. Adjusting plates are movably mounted at the upper ends of the two movable grooves. Adjusting grooves are formed on the upper surfaces of the two adjusting plates. Fixing mechanisms are provided at the upper ends of the two adjusting grooves. Each fixing mechanism includes a fixing frame. Adjusting blocks are fixedly mounted on the lower end faces of the two fixing frames. Sliding grooves are formed on the inner walls on both sides of the two fixing frames.

[0007] A lower fixing plate is slidably disposed between the inner walls on both sides of the two fixing frames near the lower end, and an upper fixing plate is disposed between the inner walls on both sides of the two fixing frames near the upper end. A transmission mechanism is fixedly disposed on one side of the lower fixing plate near the lower end. The transmission mechanism includes a movable plate. A transmission groove is opened at the upper end of the movable plate. A servo motor is disposed near the upper end of the transmission groove. A printing roller body is disposed between the two fixing mechanisms.

[0008] Furthermore, a rotating rod is rotatably embedded at the midpoint of the upper end face of each of the two fixing frames, and a first screw is rotatably embedded at the lower end face of the rotating rod. The first screw is fixedly mounted on the upper end face of the upper fixing plate near its lower end. Rubber pads are fixedly embedded on the lower end face of the upper fixing plate and the upper end face of the lower fixing plate. Threaded rods are rotatably embedded in each of the two sliding grooves. The two lower fixing plates are slidably embedded in the sliding grooves opened in the two fixing frames on both sides. The two lower fixing plates are respectively threaded onto the outer surfaces of the two threaded rods located in the same fixing frame.

[0009] Furthermore, a first bevel gear is fixedly provided on the lower end face of both threaded rods, a drive shaft is embedded in the lower end of both fixed frames, and a second bevel gear is fixedly provided on both sides of the two drive shafts. Among the four first bevel gears, the two first bevel gears located inside the same fixed frame are respectively meshed with the two second bevel gears.

[0010] Furthermore, a second screw is rotatably embedded in the transmission groove, and the servo motor is slidably embedded in the transmission groove at its lower end. The lower end of the servo motor is threaded onto the outer surface of the second screw. An embedding groove is opened on one side of the printing roller body, and an embedding block is fixedly installed at the output end of the servo motor. The embedding block and the embedding groove are fitted together.

[0011] Furthermore, each of the two fixed frames has an adjusting block fixedly installed on its lower end face. The two adjusting blocks are movably embedded in the adjusting grooves. An adjusting rod is rotatably embedded in each of the two adjusting grooves. The two adjusting blocks are threaded onto the outer surfaces of the two adjusting rods.

[0012] Furthermore, sleeves are movably fitted on both outer surfaces of the printing roller body. The two sleeves are respectively movably positioned between the upper and lower fixed plates in the two fixed frames. Movable rods are threadedly embedded on one side of the upper surface of the two adjusting plates near the front and rear ends. The four movable rods are respectively movably embedded in the two movable slots.

[0013] Furthermore, mounting brackets are fixedly installed on one side of the upper surface of the base plate near the front and rear ends, a winding device is fixedly installed on the other side of the upper surface of the base plate, and support plates are fixedly installed on both sides of the lower surface of the base plate near the front and rear ends.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a printing machine that facilitates the assembly and disassembly of printing rollers. By movably setting an adjusting plate on the upper end face of the base plate and fixing a fixing mechanism at the upper end, the printing roller body with sleeves on both sides of the outer surface can be clamped and fixed. At the same time, by adjusting the position of the two fixing mechanisms, the printing roller body can be more easily disassembled and installed. After the movable rods are rotatably embedded on both sides of the upper end face of the adjusting plate, the movable rods can be movably embedded in the opened movable grooves. When it is necessary to move and adjust the position of the printing roller body, the rotating rod can be rotated so that the lower end of the rotating rod is pressed and fitted against the inner wall of the movable groove, thereby fixing the position of the moved printing roller body and improving the use of the printing machine.

[0016] 2. This utility model proposes a printing machine that facilitates the assembly and disassembly of printing rollers. By setting a fixing mechanism on the upper end face of two adjusting plates, the height of the printing roller body can be adjusted according to different usage conditions while it is being installed and fixed. The position and height of the lower fixing plate can be adjusted by rotating the threaded rod. After the printing roller body is placed on the upper end of the two lower fixing plates, the rotating rod can be rotated to drive the upper fixing plate to clamp and fix the printing roller, thereby effectively installing and fixing the printing roller body after the height position is adjusted. At the same time, after a transmission mechanism is fixed on one side of the lower fixing plate in one of the fixing mechanisms, the servo motor in the transmission mechanism can drive the printing roller body to rotate, thereby improving the use of the printing machine.

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

[0027] Reference Figures 1 to 7 A printing machine that facilitates the assembly and disassembly of printing rollers includes a base plate 6. A printing plate 2 is fixedly installed at the midpoint of the upper surface of the base plate 6. Movable grooves 7 are provided at the midpoints of the front and rear ends of the upper surface of the base plate 6. Adjusting plates 9 are movably installed at the upper ends of the two movable grooves 7. Adjusting grooves 12 are provided at the upper surfaces of the two adjusting plates 9. Fixing mechanisms 4 are provided at the upper ends of the two adjusting grooves 12. Each fixing mechanism 4 includes a fixing frame 401. Adjusting blocks 402 are fixedly installed at the lower surfaces of the two fixing frames 401. Sliding grooves 407 are provided on the inner walls on both sides of the two fixing frames 401.

[0028] A lower fixing plate 403 is slidably disposed between the inner walls on both sides of the two fixing frames 401 at the lower end, and an upper fixing plate 405 is disposed between the inner walls on both sides of the two fixing frames 401 at the upper end. A transmission mechanism 8 is fixedly disposed on one side of the lower fixing plate 403 at the lower end. The transmission mechanism 8 includes a movable plate 802. A transmission groove 804 is opened on the upper surface of the movable plate 802. A servo motor 801 is disposed at the upper end of the transmission groove 804. A printing roller body 3 is disposed between the two fixing mechanisms 4.

[0029] Specifically, after the printing plate 2 is fixedly installed on the upper surface of the base plate 6, it can better assist the printing machine in printing. After the movable groove 7 is opened on the upper surface of the base plate 6, the adjusting plate 9 and the fixing mechanism 4 can be moved more easily. The two fixing mechanisms 4 can more conveniently install and disassemble the printing roller body 3. At the same time, after adjusting one of the threaded rods 408 in the fixing mechanism 4, the height of the lower fixing plate 403 can be adjusted, thereby better adjusting the height of the printing roller body 3 after installation and improving the applicability of the printing roller body 3. After the transmission mechanism 8 is set on one side of the lower fixing plate 403, the servo motor 801 in the transmission mechanism 8 can be fitted and connected to one side of the printing roller body 3, so that the servo motor 801 can drive the printing roller body 3 to rotate.

[0030] Reference Figure 5 and Figure 6 A rotating rod 404 is rotatably embedded at the midpoint of the upper end face of each of the two fixed brackets 401. A first screw 4011 is rotatably embedded at the lower end face of the rotating rod 404. The first screw 4011 is fixedly mounted on the upper end face of the upper fixed plate 405 near its lower end. Rubber pads 406 are fixedly embedded on the lower end face of the upper fixed plate 405 and the upper end face of the lower fixed plate 403. Threaded rods 408 are rotatably embedded in each of the two sliding grooves 407. The two lower fixed plates 403 are slidably embedded in the sliding grooves 407 opened in the two fixed brackets 401 on both sides. The two lower fixed plates 403 are respectively threaded onto the outer surfaces of the two threaded rods 408 located in the same fixed bracket 401.

[0031] Specifically, after the rotating rod 404 is rotatably embedded at the midpoint of the upper end face of the fixing frame 401, the first screw 4011 can be rotatably embedded inside the lower end face of the rotating rod 404. At the same time, after the upper fixing plate 405 and the lower end face of the first screw 4011 are fixedly connected, the upper fixing plate 405 can be moved and adjusted when the rotating rod 404 rotates, so as to better install and fix the printing roller body 3. After the sliding grooves 407 are opened on both sides of the fixing frame 401, the lower fixing plate 403 can be moved up and down in the fixing frame 401. At the same time, after the rubber pads 406 are embedded and fixed in the upper fixing plate 405 and the lower fixing plate 403, the fixing effect of the printing roller can be improved.

[0032] Reference Figure 6 The lower end faces of the two threaded rods 408 are each fixedly provided with a first bevel gear 409, and the lower end of the two fixed frames 401 are each embedded with a drive shaft 4010. The two drive shafts 4010 are each fixedly provided with a second bevel gear 4012 on both sides. Among the four first bevel gears 409, the two first bevel gears 409 located inside the same fixed frame 401 are respectively meshed with the two second bevel gears 4012.

[0033] Specifically, after the first bevel gear 409 is fixedly installed on the lower end face of the threaded rod 408, it can mesh with the second bevel gear 4012 fixedly installed at one end of the transmission shaft 4010, so that when one threaded rod 408 rotates, it drives the other threaded rod 408 to rotate synchronously, thereby adjusting the height of the threaded lower fixed plate 403.

[0034] Reference Figure 4 and Figure 7 A second screw 805 is rotatably embedded in the transmission groove 804. A servo motor 801 is slidably embedded in the transmission groove 804 at its lower end. The lower end of the servo motor 801 is threaded onto the outer surface of the second screw 805. An embedding groove 15 is opened on one side of the printing roller body 3. An embedding block 803 is fixedly installed at the output end of the servo motor 801. The embedding block 803 and the embedding groove 15 are fitted together.

[0035] Specifically, after the second screw 805 is rotatably embedded in the transmission groove 804, the servo motor 801 in the transmission groove 804 can be threaded onto the outer surface of the second screw 805 at its lower end. This allows the second screw 805 to drive the servo motor 801 to engage or disengage from one end of the printing roller body 3. Meanwhile, the embedded block 803 fixedly installed on one side of the servo motor 801 can better engage with the embedded groove 15 opened on one side of the printing roller body 3, thereby enabling the servo motor 801 to drive the printing roller body 3 to rotate more effectively.

[0036] Reference Figure 2 and Figure 3 Two adjusting blocks 402 are fixedly installed on the lower end face of the two fixed brackets 401. The two adjusting blocks 402 are movably embedded in the adjusting grooves 12. Adjusting rods 14 are rotatably embedded in the two adjusting grooves 12. The two adjusting blocks 402 are threaded onto the outer surface of the two adjusting rods 14.

[0037] Specifically, after the adjusting block 402 is fixedly installed at the lower end of the fixed frame 401, the fixed frame 401 can be movably embedded into the adjusting groove 12 through the adjusting block 402. At the same time, the adjusting rod 14 is rotatably embedded in the adjusting groove 12. After the adjusting block 402 is threaded onto the adjusting rod 14, the adjusting rod 14 can be rotated to drive the fixed frame 401 and the adjusting block 402 to move in position.

[0038] Reference Figure 3 and Figure 4The outer surfaces of both sides of the printing roller body 3 are movably fitted with sleeves 11. The two sleeves 11 are respectively movably set between the upper fixed plate 405 and the lower fixed plate 403 set in the two fixed frames 401. The upper end face of the two adjusting plates 9 is threaded with movable rods 13 near the front end and the rear end. The four movable rods 13 are respectively movably embedded in the two movable slots 7.

[0039] Specifically, after sleeves 11 are fitted onto the outer surfaces of both sides of the printing roller body 3, the printing roller body 3 can rotate better within the sleeves 11. When the upper fixing plate 405 and the lower fixing plate 403 fix the printing roller body 3, they clamp and fix the sleeves 11, so that the printing roller body 3 can rotate better even when its position is fixed. At the same time, after the movable rod 13 is threadedly embedded on the upper end face of the adjusting plate 9, the lower end of the movable rod 13 can be set in the movable groove 7. The position of the adjusting plate 9 can be fixed by rotating the movable rod 13.

[0040] Reference Figure 1 and Figure 2 Mounting brackets 5 are fixedly installed on one side of the upper surface of the base plate 6 near the front and rear ends, and a winding device 1 is fixedly installed on the other side of the upper surface of the base plate 6. Support plates 10 are fixedly installed on both sides of the lower surface of the base plate 6 near the front and rear ends.

[0041] Specifically, after the mounting brackets 5 are fixedly installed on the upper surface of the base plate 6 near the front and rear ends, the materials to be printed can be installed and fixed. At the same time, the winding device 1 fixedly installed on the other side of the base plate 6 can roll up and store the printed materials. The support plate 10 fixedly installed on the lower surface of the base plate 6 can serve as a support for the printing machine.

[0042] Working Principle: During use, the user can install and fix the material to be printed on the two mounting brackets 5. Simultaneously, the user can adjust the position of the two fixing mechanisms 4 according to different needs. After moving, the movable rod 13 in the adjusting plate 9 can be rotated to fix the position of the adjusting plate 9 and the fixing mechanism 4. After fixing, the user can also adjust the height of the printing roller body 3 by adjusting the lower mounting plate in the fixing mechanism 4, thus effectively adjusting the installation height of the printing roller body 3. After the sleeves 11 are movably fitted on both sides of the outer surface of the printing roller body 3, the printing roller body 3 can be placed on the upper part of the two adjusted lower height plates. The rotating rod 404 can be rotated to drive the upper fixing plate 405 to clamp and fix the printing roller body 3. After fixing the printing roller body 3, the transmission mechanism 8 on one side of one of the lower fixing plates 403 can be adjusted to move its position. This allows the servo motor 801, which is installed therein, to be engaged and connected to one side of the printing roller body 3 through the fixed insert block 803, thereby enabling the servo motor 801 to drive the printing roller body 3 to rotate, thus improving the operation of the printing machine.
