Description

Technical Field

[0001] The present application relates to the field of printing plate roller processing, and in particular to a pipe correction device. Background Art

[0002] Printing plate rollers are important components in the printing industry. Through contact with the plate and the pressure of the machine, ink is transferred to the printing material, thereby replicating patterns or text. As the raw material of printing plate rollers, pipe fittings are generally formed by curling and welding metal plates. Due to the influence of processing accuracy, the cross-section of the pipe fittings cannot reach the standard circle after forming, so it needs to be rounded through orthopedic equipment.

[0003] In the prior art, the orthopedic equipment includes a frame, two rotating rollers rotatably connected to the frame, a positioning roller detachably connected to the frame, and a driving device for driving the rotating roller to rotate, and the positioning roller is arranged between the upper sides of the two rotating rollers. First, the pipe fitting is sleeved on the outer side of the positioning roller, and then the positioning roller is installed on the frame, and then the driving device is started. Through the rotation of the two rotating rollers, the pipe fitting is driven to rotate, so that the pipe fitting gradually becomes round and the orthopedic treatment is completed. After the orthopedic treatment is completed, the positioning roller is removed, and then the pipe fitting is removed from the positioning roller.

[0004] The above technical solutions generally have the following technical defects: the disassembly and assembly of the positioning rollers is relatively troublesome and needs to be done manually, resulting in a long time required for pipe loading and loading, which affects the correction efficiency. Summary of the invention

[0005] In order to improve the orthopedic efficiency, the present application provides a pipe orthopedic device.

[0006] The pipe orthopedic device provided in this application adopts the following technical solution:

[0007] A pipe correction device, comprising a frame, a rotating roller, a positioning roller and a driving device, wherein two rotating rollers are provided and are rotatably connected to the frame, the positioning roller is provided between the upper sides of the two rotating rollers, the driving device is used to drive the rotating roller to rotate, and a pressing device is provided at one end of the positioning roller and a locking device is provided at the other end;

[0008] The pressing device comprises a support frame fixedly connected to the frame, a pressing cylinder mounted on the support frame, and a rotating seat connected to the positioning roller, wherein one end of the rotating seat close to the positioning roller is rotatably connected to the frame, and the other end is located below the pressing cylinder;

[0009] The locking device comprises a lifting seat, a locking seat hinged to the upper side of the lifting seat, a rotating assembly for driving the locking seat to rotate, and a driving member for driving the lifting seat to move up and down. The end of the positioning roller away from the rotating seat is inserted between the lifting seat and the locking seat.

[0010] By adopting the above technical solution, after the correction is completed, the driving part is started first to make the lifting seat and the locking seat move up. At this time, the positioning roller abuts against the lifting seat, and there is a gap between the positioning roller and the inner top wall of the locking seat to facilitate the rotation of the locking seat. Then the rotating assembly is started to drive the locking seat to rotate away from the positioning roller, so that the locking seat and the positioning roller are misaligned. Then the downward pressure cylinder is started to drive the rotating seat to rotate downward away from the positioning roller, thereby lifting the positioning roller to an inclined state. Finally, the corrected pipe fittings are taken out manually, and then the pipe fittings to be corrected are installed.

[0011] The positioning roller of the present application has two states, one is the correction state, and the other is the loading and unloading state. The two states can be switched automatically, so the positioning roller does not need to be manually disassembled and assembled, which is conducive to shortening the time of pipe loading and unloading, thereby improving the correction efficiency.

[0012] Optionally, the rotating assembly includes a connecting bar fixedly connected to the lifting seat, a fixing bar fixedly connected to the locking seat, a fixing frame fixedly connected to the fixing bar, and a rotating cylinder hinged in the fixing frame, wherein the piston rod of the rotating cylinder is connected to an articulated seat, and the articulated seat is hinged to the connecting bar.

[0013] By adopting the above technical solution, the rotating assembly moves up and down with the lifting seat. When unlocking is required, the rotating cylinder is started to drive the piston rod to contract, so that the articulated seat can be rotated to be misaligned with the positioning roller.

[0014] Optionally, a slide groove for the lifting seat to slide is arranged at the upper end of the frame, a guide groove is arranged vertically on the inner wall of the slide groove, and the lifting seat is connected with a guide block inserted into the guide groove.

[0015] By adopting the above technical solution, a guide is provided for the sliding of the lifting seat, and the lateral gravity of the rotating assembly on the connection between the lifting seat and the driving member is reduced.

[0016] Optionally, a buffer pad is connected to the upper side of the lifting seat.

[0017] By adopting the above technical solution, after the pipe is loaded, the piston rod of the downward pressure cylinder contracts, and the positioning roller falls on the lifting seat under the action of gravity. The buffer pad can reduce the collision between the positioning roller and the lifting seat, thereby reducing the stress on the driving part and avoiding the trouble of accidental damage to the driving part.

[0018] Optionally, the locking seat is fixedly connected to a hinge shaft, the lifting seat is provided with a hinge hole for the hinge shaft to pass through, the lifting seat is provided with a clearance groove for the buffer pad to be inserted, the clearance groove is connected to the hinge hole, a lifting plate fixedly connected to the lower side of the buffer pad is provided in the clearance groove, a cam is fixedly sleeved in the middle of the hinge shaft, and the cam is pressed against the lower side of the lifting plate.

[0019] By adopting the above technical solution, when unlocking, the locking seat rotates to drive the hinge shaft to rotate, the cam pushes the lifting plate upward, and the buffer pad extends out of the clearance groove to play a buffering role. After the positioning roller falls, the locking seat is reset to the locked state. At this time, the buffer pad moves down with the rotation of the locking seat, so that the position of the positioning roller will not be too high to affect the rotation of the locking seat.

[0020] Optionally, the piston rod of the downward-pressing cylinder is connected to a connecting seat, and the connecting seat is rotatably connected to a roller for pressing against the rotating seat.

[0021] By adopting the above technical solution, the friction force is reduced, so that the rotating seat can rotate more smoothly.

[0022] Optionally, a rotating groove for inserting the rotating seat is provided at the upper end of the frame, a rotating shaft is connected between two inner walls of the rotating groove, and the rotating shaft is rotatably arranged to penetrate the rotating seat.

[0023] Optionally, the positioning roller includes a roller body and a positioning block rotatably connected to one end of the roller body, one end of the roller body away from the positioning block is rotatably connected to the rotating seat, the positioning block is inserted between the lifting seat and the locking seat, and the positioning block is square.

[0024] By adopting the above technical solution, the roller body rotates with the pipe fitting, reducing the wear on the inner wall of the pipe fitting. In addition, the positioning block is well fixed by the locking seat.

[0025] Optionally, the outer surface of the rotating roller is provided with anti-slip grooves.

[0026] By adopting the above technical solution, the pipe and the rotating roller are not prone to slip.

[0027] Optionally, the driving device includes a sprocket connected to one end of the rotating roller, a chain sleeved between two sprockets, and a driving motor for driving one of the sprockets to rotate.

The two states can be switched automatically, so the positioning roller does not need to be manually disassembled and assembled, which is conducive to shortening the time of pipe loading and unloading, thereby improving the correction efficiency.

The positioning roller 3 is arranged between the upper sides of the two rotating rollers 2. The outer surface of the rotating roller 2 is provided with anti-slip grooves 21. The pipe is put on the positioning roller 3 and pressed against the two rotating rollers 2. After the driving device 4 is started, the rotating roller 2 rotates to drive the pipe to rotate, so that the shape of the pipe gradually becomes round to achieve correction.

[0040] The pressing device 5 and the locking device 6 are respectively arranged at both ends of the positioning roller 3, the pressing device 5 is used to drive the positioning roller 3 to rotate, and the locking device 6 is used to fix the positioning roller 3. When the locking device 6 is unlocked, the pressing device 5 drives the positioning roller 3 to rotate to an inclined state, at which time the pipe fitting can be easily put on the positioning roller 3 or removed from the positioning roller 3, which is convenient for loading and unloading the pipe fitting.

[0041] Reference Figure 2 , Figure 3 A slide groove 11 is provided at the upper end of one side of the frame 1 close to the locking device 6. The locking device 6 includes a lifting seat 61 provided in the slide groove 11, a locking seat 62 hinged on the upper side of the lifting seat 61, a rotating assembly 63 for driving the locking seat 62 to rotate, and a driving member 64 for driving the lifting seat 61 to move up and down. The lifting seat 61 is in a convex shape, and guide blocks 611 are fixedly connected on both sides of the lifting seat 61. A guide groove 12 is vertically provided on the inner wall of the slide groove 11 for the guide blocks 611 to be inserted and slide up and down. The driving member 64 is a hydraulic cylinder, the cylinder body is fixedly connected to the frame 1, and the piston rod is arranged upward and fixedly connected to the lifting seat 61.

Therefore, when the positioning roller 3 is lowered to abut the lifting seat 61, the locking seat 62 can rotate smoothly.

[0043] Reference Figure 2 , Figure 3 The rotating assembly 63 includes a connecting bar 631, a fixing bar 632, a fixing frame 633, a rotating cylinder 634 and an articulated seat 635. The connecting bar 631 is fixedly connected to the side of the lifting seat 61 away from the pressing device 5, the fixing bar 632 is fixedly connected to the side of the locking seat 62 away from the pressing device 5, the end of the fixing bar 632 is fixedly connected to the fixing frame 633, and the fixing frame 633 is U-shaped. The rotating cylinder 634 is arranged in the fixing frame 633, the cylinder body of the rotating cylinder 634 is rotatably connected to the fixing frame 633, the piston rod is fixedly connected to the articulated seat 635, and the articulated seat 635 is articulated to the connecting bar 631. The two states can be switched automatically, so the positioning roller 3 does not need to be manually disassembled and assembled, which is conducive to shortening the time of pipe loading and unloading, thereby improving the orthopedic efficiency.

[0044] The positioning roller 3 of the present application has two states, one is the orthopedic state, and the other is the loading and unloading state. In the orthopedic state, the pipe fittings sleeved on the outer surface of the positioning roller 3 are pressed against the two rotating rollers 2, and the locking seat 62 is pressed against the positioning roller 3, so that the positioning roller 3 is not easy to loosen. In the loading and unloading state, the locking seat 62 is misaligned with the positioning roller 3, and the pressing device 5 drives the positioning roller 3 to rotate to an inclined state. At this time, the end of the positioning roller 3 away from the pressing device 5 is open, which is convenient for loading and unloading pipe fittings.

[0045] The process of switching from the orthopedic state to the loading and unloading state is as follows: first start the driving member 64 to move the lifting seat 61 and the locking seat 62 upward. At this time, the positioning roller 3 abuts against the lifting seat 61, and there is a gap between the positioning roller 3 and the inner top wall of the locking seat 62. Then start the rotating cylinder 634 to contract its piston rod, driving the locking seat 62 to rotate until it is misaligned with the positioning roller 3, and then start the pressing device 5 to drive the positioning roller 3 to rotate to an inclined state.

[0046] The process of switching from the loading and unloading state to the correction state is as follows: the pressing device 5 releases the positioning roller 3, and the positioning roller 3 naturally drops down to contact the lifting seat 61, and then the rotating cylinder 634 is started to extend its piston rod, and the locking seat 62 rotates to the upper side of the positioning roller 3, and then the driving member 64 is started to drive the lifting seat 61 and the locking seat 62 to descend until the locking seat 62 is close to the positioning roller 3.

A buffer pad 65 is provided on the upper side of the lifting seat 61, and the lifting seat 61 is provided with a clearance groove 613 for the buffer pad 65 to be vertically inserted, and the clearance groove 613 is connected with the hinge hole 612. A lifting plate 66 is fixedly connected to the lower side of the buffer pad 65, and the lifting plate 66 is U-shaped and vertically slidably connected to the inside of the clearance groove 613. A cam 68 is fixedly sleeved in the middle of the hinge shaft 67, and the cross section of the cam 68 is elliptical, and the cam 68 is pressed against the lower side of the lifting plate 66.

[0048] In the correction state, the long side of the cam 68 is horizontally arranged, and the buffer pad 65 is located in the clearance groove 613. When switching to the loading and unloading state, the locking seat 62 rotates to drive the hinge shaft 67 to rotate, and the cam 68 rotates to push the lifting plate 66 upward, and the buffer pad 65 extends out of the clearance groove 613 to play a buffering role. At this time, the buffer pad 65 can reduce the collision between the positioning roller 3 and the lifting seat 61, thereby reducing the stress on the driving member 64 and avoiding the trouble of accidental damage to the driving member 64.

[0049] Reference Figure 1 , Figure 5 The pressing device 5 comprises a support frame 51 fixedly connected to the frame 1, a pressing cylinder 52 mounted on the support frame 51, and a rotating seat 53 connected to the positioning roller 3. The cylinder body of the pressing cylinder 52 is fixedly connected to the support frame 51, the piston rod is arranged downward and fixedly connected to a connecting seat 54, and the connecting seat 54 is rotatably connected to a roller 55 for pressing against the rotating seat 53.

When the downward pressure cylinder 52 is started, the piston rod is extended, and the roller 55 drives the rotating seat 53 to rotate, thereby driving the positioning roller 3 to be lifted to a tilted state.

[0051] Reference Figure 1 , Figure 5 The positioning roller 3 includes a roller body 31 and a positioning block 32 rotatably connected to one end of the roller body 31. The positioning block 32 is square. One end of the roller body 31 away from the positioning block 32 is rotatably connected to the rotating seat 53. The positioning block 32 is inserted between the lifting seat 61 and the locking seat 62. The roller body 31 rotates with the pipe fitting to reduce the wear on the inner wall of the pipe fitting.

At this time, the positioning roller 3 abuts against the lifting seat 61, and there is a gap between the positioning roller 3 and the inner top wall of the locking seat 62 to facilitate the rotation of the locking seat 62. Then, the rotating cylinder 634 is started to drive the locking seat 62 to rotate away from the positioning roller 3, so that the locking seat 62 and the positioning roller 3 are misaligned. Then, the pressing cylinder 52 is started to drive the rotating seat 53 to rotate downward away from the end of the positioning roller 3, thereby lifting the positioning roller 3 to an inclined state. Finally, the corrected pipe fittings are manually taken out, and then the pipe fittings to be corrected are installed.
