Description

Technical Field

[0001] This utility model relates to the field of printing roller technology, specifically to a printing roller welding drive rotation 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. This component is widely used in printing presses from brands such as Heidelberg, Roland, and Beiren. Matching models include components such as ink roller holders and dampening roller holders, and the materials cover polyurethane, rubber, copper bushings, and other types.

[0003] The printing roller consists of a roller cylinder and a printing roller shaft. After assembly, welding is required. Existing welding methods involve manually adjusting the orientation to weld the connection between the roller cylinder and the printing roller shaft, or using hoisting equipment to lift the whole assembly, align it, clamp it, and drive it to rotate for welding. This method cannot achieve automated lifting and rotation to assist welding, which greatly reduces welding efficiency. Therefore, we propose a printing roller welding drive rotation device to solve this technical deficiency. Utility Model Content

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

[0005] To achieve the above objectives, the present invention provides the following technical solution: a printing roller welding drive rotation device, including a placement table, on the left and right sides of the upper end of the placement table, an opening groove is provided, the bottom wall of the placement table is provided with a pair of hydraulic push rods respectively located in the opening groove, the push rod of the hydraulic push rod is provided with a loading plate located in the opening groove, the upper end of the loading plate is provided with a directional slide groove, a pair of movable seats slide in the directional slide groove, the opposite sides of the movable seats are provided with rollers, and the loading plate is provided with a drive assembly for driving the movable seats to move in opposite directions;

[0006] A fixed plate is provided on the left side of the placement platform. A clamping cylinder 1 is rotatably mounted on the center of the fixed plate. A support base is provided on the right side of the placement platform. A hydraulic push rod 2 is provided on the right side of the support base. A connecting seat is provided at the push rod of the hydraulic push rod 2. A drive motor is provided on the right side of the connecting seat. A clamping cylinder 2 with the same center as the clamping cylinder is provided at the output end of the drive motor. Both the clamping cylinder 1 and the clamping cylinder 2 are provided with clamping components for clamping the printing roller shaft head.

[0007] Using the above technical solution, the placement platform can center the assembled printing roller, so that the printing roller is located between the front and rear rollers. The drive component drives the moving seat to move in the directional chute, so that the moving seat drives the roller to move synchronously and lift the printing roller. After lifting, the hydraulic push rod pushes the loading plate to move, which drives the roller to move upward synchronously, thus lifting the printing roller.

[0008] After being lifted, the connecting seat is moved by the hydraulic push rod two on the support base, so that the clamping cylinder two is inserted into the shaft head on the printing roller, and the printing roller is moved so that the shaft head at the other end is inserted into the clamping cylinder one on the fixed plate, thereby achieving the clamping of the printing roller shaft head. With the help of the clamping components, the shaft head is clamped and fixed, ensuring that after the shaft head is fixed, the printing roller is driven by the drive motor to rotate on the roller, which assists in the welding work.

[0009] As a preferred technical solution of this utility model, the rollers are symmetrically distributed front and back based on the center of the loading plate, and the driving component includes a servo motor located on the front side of the loading plate. The output shaft of the servo motor is provided with a bidirectional threaded rod that rotates with the inner wall of the loading plate, and the bidirectional threaded rod is threadedly connected to the movable seat.

[0010] The bidirectional threaded rod is based on the center of symmetry between the two rollers, and the front and rear sides of the bidirectional threaded rod are respectively provided with a forward thread groove and a reverse thread groove that are threaded to the movable seat.

[0011] Using the above technical solution, the servo motor drives the bidirectional threaded rod to rotate. The forward and reverse threaded grooves on the bidirectional threaded rod are respectively connected to the threaded seat, and the directional slide groove limits the linear sliding of the moving seat, thereby driving the moving seat to move in opposite directions, realizing the synchronous movement of the roller, and lifting the placed printing roller.

[0012] As a preferred embodiment of this invention, the roller is a rubber wheel, but is not limited to rubber wheels.

[0013] In a preferred embodiment of this invention, the centers of the first clamping cylinder and the second clamping cylinder are on the same straight line as the center of the roller.

[0014] By adopting the above technical solution, it is ensured that clamping cylinder one and clamping cylinder two can be positioned and inserted into the outside of the shaft heads on both sides of the printing roller.

[0015] As a preferred technical solution of this utility model, the clamping assembly includes a plurality of hydraulic cylinders arranged in annularly at equal distances outside the clamping cylinder one and the clamping cylinder two, and the push rod of the hydraulic cylinder is provided with a clamping head located inside the clamping cylinder one and the clamping cylinder two.

[0016] Using the above technical solution, the hydraulic cylinder works to drive the clamping head to move, thereby clamping the printing roller shaft head.

[0017] As a preferred embodiment of this utility model, the clamping head is a rubber block, but is not limited to a rubber block.

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

[0019] The printing roller welding drive rotation device has a placement platform that centers the assembled printing roller between the front and rear rollers. The drive component drives the moving seat to move in the directional chute, which enables the moving seat to move the rollers synchronously and lift the printing roller. After lifting, the hydraulic push rod pushes the loading plate to move, which drives the rollers to move upward synchronously, thus lifting the printing roller.

[0020] After being lifted, the connecting seat is moved by the hydraulic push rod two on the support base, so that the clamping cylinder two is inserted into the shaft head on the printing roller, and the printing roller is moved so that the shaft head at the other end is inserted into the clamping cylinder one on the fixed plate, thereby realizing the clamping of the printing roller shaft head. With the help of the clamping components, the shaft head is clamped and fixed. After the shaft head is fixed, the printing roller is driven to rotate on the roller by the drive motor. Compared with the existing technology, it realizes automatic clamping and driving rotation of the printing roller, assists in welding, and improves welding efficiency. Attached Figure Description

The rollers 8 are made of rubber, which has good elasticity and shock absorption performance, but are not limited to rubber wheels and can be replaced according to actual use.

[0030] The loading plate 4 is equipped with a drive assembly that drives the moving seat 7 to move in opposite directions. The drive assembly includes a servo motor 5 that is fixed to the front surface of the loading plate 4 by bolts. The servo motor 5 is a high-precision servo motor with good control accuracy and torque output. A bidirectional threaded rod 9 that rotates with the inner wall of the loading plate 4 is fixed at the output shaft of the servo motor 5. The bidirectional threaded rod 9 is made of high-strength alloy steel and its surface is precision machined to ensure thread accuracy. The bidirectional threaded rod 9 is threadedly connected to the moving seat 7. Based on the center of symmetry between the two rollers 8, the front and rear sides of the bidirectional threaded rod 9 are respectively provided with a forward thread groove and a reverse thread groove that are threadedly connected to the moving seat 7.

[0031] A fixing plate 10 is fixed to the center of the left side surface of the placement platform 1. The fixing plate 10 is made of high-strength steel and has good stability and mechanical strength. A clamping cylinder 11 is rotatably mounted in the center of the fixing plate 10.

[0034] The working principle of the equipment is as follows: the assembled printing roller is placed on the placement platform 1, ensuring that the printing roller is located between the front and rear rollers 8. The servo motor 5 is started, which drives the bidirectional threaded rod 9 to rotate. The forward and reverse threaded grooves on the bidirectional threaded rod 9 are threadedly connected to the moving seat 7 respectively. Under the linear limiting sliding action of the directional slide 6, the moving seat 7 is driven to move in opposite directions. The moving seat 7 drives the rollers 8 to move synchronously, lifting the printing roller.

[0035] During the lifting and jacking process of the printing roller, the hydraulic push rod 3 pushes the loading plate 4 to move, which drives the roller 8 to move upward synchronously, thereby lifting the printing roller. After being lifted, the two ends of the printing roller are aligned with the clamping cylinder 11 on the fixed plate 10 and the clamping cylinder 2 16 on the support base 12, respectively.

[0036] The printing roller is clamped and fixed by activating the hydraulic push rod 13, which pushes the connecting seat 14 to move, so that the clamping cylinder 16 is inserted into the shaft head on the printing roller and pushes the printing roller to move, so that the shaft head at the other end is inserted into the clamping cylinder 11 on the fixing plate 10. The hydraulic cylinder 17 works to push the clamping head 18 to move, thereby clamping and fixing the shaft head of the printing roller.

[0037] The printing roller is driven and rotated by the drive motor 15, which drives the clamping cylinder 16 to rotate, thereby driving the printing roller to rotate on the roller 8. During the rotation, the roller 8 provides stable support for the printing roller, ensuring the smooth progress of the welding process.

[0038] After welding is completed, the hydraulic cylinder 17 is reset, releasing the clamping head 18 from clamping the printing roller shaft. The hydraulic push rod 13 is reset, driving the clamping cylinder 16 and the printing roller to reset synchronously. The hydraulic push rod 3 is reset, driving the roller 8 and the printing roller to move down synchronously, completing the disassembly.

[0039] Technological advantages, automated clamping and rotation: Through the coordinated work of hydraulic push rods, servo motors and hydraulic cylinders, the automatic clamping and driving rotation of the printing roller are realized, which significantly improves welding efficiency.
