Description

Technical Field

[0001] This utility model relates to the field of printing roller production technology, specifically to a printing roller assembly device. Background Technology

[0002] Printing rollers are core components of offset printing presses, mainly used to transfer ink and dampening solution. The microporous structure of their surface directly affects printing quality.

[0003] The printing roller consists of a shaft head and a printing roller body. During assembly and welding, workers insert the shaft head into the side of the printing roller body and then use a rubber hammer to evenly tap the shaft head to achieve the embedding and connection between the shaft head and the printing roller body. However, the tapping method is prone to uneven force, causing the shaft head to shift and fail to be inserted. It is also time-consuming and labor-intensive. Therefore, we propose a printing roller assembly equipment to solve this defect of the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a printing roller assembly device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a printing roller assembly device, comprising a base and a printing roller placement groove disposed on the upper end of the base, a support frame provided on both the front and rear sides of the upper end of the base, a mounting seat provided between the upper ends of the support frames, a pair of movable seats sliding on the upper end of the mounting seat, and a drive component provided on the mounting seat to drive the movable seats to move in opposite directions.

[0006] The upper end of the movable seat is provided with an L-shaped rod located on the side of the base. The other end of the L-shaped rod is provided with a collar concentric with the printing roller placement groove. The collar is provided with a clamping component for centrally clamping the printing roller inserted into the collar.

[0007] The inner side of the L-shaped rod is provided with a hydraulic push rod. The push rod of the hydraulic push rod is provided with a tube located outside the collar and concentric with the collar. The tube is used to insert the shaft head, and the tube is provided with a positioning component for centering and clamping the shaft head.

[0008] Using the above technical solution, the printing roller body is placed in the printing roller placement groove on the base. The driving component drives the moving seat to move in the mounting seat on the support frame, and simultaneously drives the collar on the L-shaped rod to move, respectively fitting on the outer sides of both ends of the printing roller body. The clamping component then clamps the printing roller body in the center. In addition, by inserting the shaft head into the insert cylinder, the positioning component clamps and positions the shaft head in the center, making the shaft head concentric with the side opening of the printing roller body. This facilitates the hydraulic push rod to drive the shaft head in the insert cylinder to move and embed it into the opening of the printing roller body, thus realizing the rapid assembly of the printing roller.

[0009] As a preferred technical solution of this utility model, the driving component includes a bidirectional output motor located at the center of the bottom wall of the mounting base. The bidirectional output motor is located between the movable seats. Both output ends of the bidirectional output motor are provided with threaded rods that are threadedly connected to the two movable seats respectively. The other end of the threaded rod is connected to the mounting base for rotation.

[0010] As a preferred embodiment of this utility model, a directional guide rod is provided between the left and right side walls of the inner cavity of the mounting base, through which the movable base passes.

[0011] Using the above technical solution, the bidirectional output motor drives the threaded rod to rotate. By utilizing the threaded connection between the threaded rod and the movable seat, as well as the limiting sliding of the movable seat by the directional guide rod, the movable seat is driven to move in opposite directions within the mounting base when the threaded rod rotates in both directions.

[0012] As a preferred embodiment of this utility model, the movable base is symmetrically distributed on the left and right sides, with the bidirectional output motor as the center.

[0013] The above technical solution facilitates symmetrical movement of the mobile seat based on the center.

[0014] As a preferred technical solution of this utility model, the printing roller placement groove is arc-shaped, and the clamping assembly includes hydraulic push rods two that are equidistantly distributed in a ring outside the collar, and the push rod of the hydraulic push rod two is provided with a clamping head located inside the collar.

[0015] Using the above technical solution, the hydraulic push rod II drives the clamping head to move, thereby achieving centered clamping of the printing roller body inside the collar.

[0016] As a preferred embodiment of this utility model, the positioning component includes multiple hydraulic push rods three arranged in a ring at equal intervals outside the insert, and the push rods of the hydraulic push rods three are provided with positioning heads located inside the insert.

[0017] Using the above technical solution, the hydraulic push rod three-function drives the positioning head to move and center the shaft head inside the insert.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] This printing roller assembly equipment, employing the aforementioned technical solution, involves placing the printing roller body in the printing roller placement groove on the base. A drive assembly moves the movable seat within the mounting base on the support frame, simultaneously moving the collars on the L-shaped rod. These collars are respectively fitted onto the outer sides of both ends of the printing roller body. A clamping assembly then centrally clamps the printing roller body. Furthermore, by inserting the shaft head into the insert cylinder, a positioning assembly centrally clamps and positions the shaft head, ensuring it is concentric with the side opening of the printing roller body. This facilitates the movement of the shaft head within the insert cylinder by the hydraulic push rod, allowing it to embed into the opening of the printing roller body. Compared to manual assembly of the shaft head and printing roller body, this method avoids misalignment and low assembly efficiency, achieving rapid assembly of the printing roller.

[0025] 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.

[0026] Please see Figs. 1 to 4 The printing roller assembly equipment in this embodiment mainly includes a base 1, a support frame 3, a mounting seat 13, a movable seat 4, an L-shaped rod 8, a collar 9, an insert cylinder 14, as well as a drive assembly, a clamping assembly, and a positioning assembly.

[0027] The base 1 serves as the supporting foundation for the entire equipment. A printing roller placement groove 2 is provided at its upper end. The printing roller placement groove 2 is arc-shaped and is used to place the printing roller body to ensure that the printing roller body is stable during assembly. Support frames 3 are fixed on the front and rear sides of the upper surface of the base 1. The support frames 3 are set perpendicular to the upper surface of the base 1 and serve to support the mounting base 13.

[0028] Mounting base 13 is horizontally fixed between the upper ends of two support frames 3. The upper end of mounting base 13 is provided with two movable seats 4, which can slide on mounting base 13. A directional guide rod 7 is fixed between the left and right side walls of the inner cavity of mounting base 13. The directional guide rod 7 passes through the movable seat 4, providing guidance and limiting function for the sliding of the movable seat 4, and ensuring the stability of the movement of the movable seat 4.

[0029] Each movable seat 4 has an L-shaped rod 8 on its upper surface. One end of the L-shaped rod 8 is fixed to the upper end of the movable seat 4, and the other end extends to the side of the base 1. The other end of the L-shaped rod 8 is fixed with a collar 9 that is concentric with the printing roller placement groove 2. The collar 9 is used to fit on the outside of both ends of the printing roller body.

[0030] A hydraulic push rod 12 is fixed on the inner surface of the L-shaped rod 8. A tube 14 is fixed at the push rod of the hydraulic push rod 12. The tube 14 is located outside the collar 9 and is concentric with the collar 9. The tube 14 is used to insert the shaft head.

[0031] The mounting base 13 is equipped with a drive assembly for driving the movable seats 4 to move in opposite directions. The drive assembly includes a bidirectional output motor 5 fixed to the center of the bottom wall of the mounting base 13. The bidirectional output motor 5 is located between the two movable seats 4. Threaded rods 6 are fixed to both output ends of the bidirectional output motor 5. The other end of the threaded rods 6 is connected to the mounting base 13 for rotation. The two threaded rods 6 are threadedly connected to the two movable seats 4 respectively. The movable seats 4 are symmetrically distributed on the left and right sides based on the bidirectional output motor 5 as the center.

[0032] When the bidirectional output motor 5 is working, it drives the threaded rods 6 on both sides to rotate. Due to the limiting effect of the guide rod 7 on the moving seat 4, when the threaded rod 6 rotates in both directions, according to the thread transmission principle, the moving seat 4 will move in opposite directions within the mounting seat 13, thereby driving the L-shaped rod 8 and the collar 9 to move, so as to adapt to printing rollers of different lengths.

[0033] The clamping assembly is located on the collar 9 and is used to centrally clamp the printing roller that is fitted into the collar 9. The clamping assembly includes a plurality of hydraulic push rods 10 that are fixed to the outside of the collar 9 and are evenly distributed in a ring. In this embodiment, there are 3 hydraulic push rods 10, which are evenly distributed outside the collar 9. Each hydraulic push rod 10 has a clamping head 11 fixed at its push rod position inside the collar 9.

[0034] After the printing roller is fitted into the collar 9, the hydraulic push rod 10 operates, pushing the clamping head 11 to move towards the center of the collar 9. Multiple clamping heads 11 act simultaneously, clamping the printing roller from different directions to achieve centered fixation of the printing roller, ensuring accurate positioning of the printing roller during subsequent assembly.

[0035] The positioning component is located on the insert 14 and is used to center and clamp the shaft head inserted into the insert 14. The positioning component includes multiple hydraulic push rods 15 that are fixed to the outside of the insert 14 and are distributed at equal intervals in a ring. In this embodiment, there are 3 hydraulic push rods 15, which are evenly distributed on the outside of the insert 14. Each hydraulic push rod 15 has a positioning head 16 located inside the insert 14.

[0036] After the shaft head is inserted into the insert 14, the hydraulic push rod 15 operates, pushing the positioning head 16 to move towards the center of the insert 14. Multiple positioning heads 16 act simultaneously, clamping the shaft head from different directions, so that the shaft head and the side opening of the printing roller are concentric, thus ensuring accurate docking of the shaft head and the printing roller in the future.

[0037] Material selection: High-strength aluminum alloy or stainless steel can be used for major structural components such as base 1, support frame 3, mounting base 13, moving base 4, and L-shaped rod 8 to ensure the structural strength and stability of the equipment, while reducing the weight of the equipment and facilitating movement and installation. Wear-resistant and corrosion-resistant engineering plastics or alloy materials, such as polyoxymethylene (POM) or stainless steel, can be used for components that come into direct contact with the printing roller body and shaft head, such as collar 9, insert cylinder 14, clamping head 11, and positioning head 16, to extend the service life of the components and reduce damage to the printing roller body and shaft head.

[0038] Extended Design: To further improve the automation level and ease of operation of the equipment, a control system can be added to the equipment. The control system may include a PLC controller and a touch screen operating interface. The PLC controller can precisely control the bidirectional output motor, hydraulic push rod one, hydraulic push rod two, and hydraulic push rod three. Operators can input relevant parameters, such as the length and diameter of the printing roller, through the touch screen operating interface to realize the automated operation of the equipment.

[0039] Usage steps, placing the printing roller: Place the printing roller in the printing roller placement groove 2 on the base 1, ensuring that the printing roller is in the correct position.

[0040] Moving collar: Start the bidirectional output motor 5 to drive the threaded rod 6 to rotate, so that the moving seat 4 moves within the mounting seat 13, and synchronously drives the collar 9 on the L-shaped rod 8 to move, so that the collar 9 is respectively fitted onto the outer sides of both ends of the printing roller body.

[0041] Clamping the printing roller: Activate the hydraulic push rod 10 to push the clamping head 11 to move towards the center of the collar 9, and clamp and fix the printing roller in the center.

[0042] Insert the shaft head: Insert the shaft head into the insert 14.

[0043] Positioning the shaft head: Activate hydraulic push rod 15 to push positioning head 16 to move towards the center of insert 14, and center and clamp the shaft head.

[0044] Assemble the shaft head and printing roller body: Start the hydraulic push rod 12 to drive the shaft head inside the insert cylinder 14 to move, so that the shaft head is inserted into the opening of the printing roller body, thus completing the assembly of the printing roller.

[0045] Release components: After assembly, control the hydraulic push rod 2 10 and hydraulic push rod 3 15 to retract, releasing the clamps on the printing roller body and shaft head. Then control the bidirectional output motor 5 to rotate in the opposite direction, causing the moving seat 4 to drive the collar 9 away from the printing roller body, and remove the assembled printing roller.

[0046] In summary, this printing roller assembly equipment, through its reasonable structural design and precise control, achieves rapid and accurate assembly of printing rollers, avoiding the problems of misalignment and low assembly efficiency that occur when manually connecting the shaft head and the printing roller body. It has high practical value and significance for promotion.

[0047] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0048] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
