Description

Technical Field

[0001] The invention relates to the technical field of drying cylinder processing, in particular to a drying cylinder body welding processing equipment for papermaking. Background Art

[0002] In the papermaking process, the drying cylinder is one of the key equipment for drying paper. The drying cylinder is usually composed of a large-diameter rotating cylinder. During the drying cylinder processing, in order to improve the strength of the cylinder, several circumferentially distributed reinforcing ribs are usually set inside the cylinder. These reinforcing ribs are fixed to the inner wall of the cylinder by welding.

[0003] When welding reinforcing ribs in a drying cylinder, the welding position of each reinforcing rib is generally marked with an angle meter and a marking pen. Then, a worker enters the drying cylinder and presses a single reinforcing rib against the mark on the inner wall of the cylinder. Then, the reinforcing rib is welded with a welding gun. After welding one reinforcing rib, a reinforcing rib is placed at the next mark for welding.

[0004] However, the above welding method still has the following shortcomings: 1. When the reinforcing ribs are pressed against the inner wall of the cylinder, the mutual stability between the reinforcing ribs and the cylinder is insufficient. During the welding process, the reinforcing ribs are prone to offset relative to the inner wall of the cylinder, affecting the accuracy of the rib welding and further affecting the quality of the entire drying cylinder cylinder processing; 2. Although marks are made on the inside of the cylinder before welding the reinforcing ribs, both the marking and the subsequent pressing and welding of the reinforcing ribs are determined by workers. During this period, problems such as rib placement errors, insufficient rib stability, and welding deviations are prone to occur, which in turn affect the quality of the drying cylinder cylinder welding processing. In addition, the process of manually marking and then pressing and welding the reinforcing ribs one by one is relatively cumbersome and time-consuming. Summary of the invention

When the welding gun moves left and right along the reinforcing rib for welding, a triangular support structure is formed between connecting plate 1, connecting plate 2 and the guide rail, which improves the stability of the welding gun during moving welding, enables the welding gun to accurately weld the reinforcing rib, and further improves the quality of welding.

[0035] See also Figure 1 and Figure 2 The fixing mechanism 2 includes a plurality of inner clamping blocks 21 and outer clamping blocks 24 which are evenly distributed along the circumference of the center rod 1 and clamp the inner and outer sides of the cylinder respectively. A telescopic component 1 22 and a telescopic component 25 which respectively push the inner clamping blocks 21 and the outer clamping blocks 24 to move are installed on the center rod 1. A supporting component 23 located between the telescopic component 1 22 and the telescopic component 25 is connected between adjacent inner clamping blocks 21. The inner clamping blocks 21 and the corresponding outer clamping blocks 24 are locked with each other through a locking component 26.

[0036] See also Figure 1 , Figure 6 and Figure 7 The angle adjustment mechanism 6 includes a turntable 61 fixedly connected to the left end of the rotating drum 5 and rotatably sleeved on the outside of the central rod 1. The outside of the turntable 61 is provided with an angle limiting component for limiting its rotation angle and causing it to rotate at a fixed angle. A driving motor 69 for driving the turntable 61 to rotate is installed on the telescopic component 22.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The number of inner clamping blocks 21 and outer clamping blocks 24 are both three and the outer clamping block 24 is located on the outside of the inner clamping block 21. The telescopic component 1 22 and the telescopic component 2 25 are both three-jaw chucks and are fixedly connected. The telescopic component 2 25 is located on the side of the telescopic component 1 22 away from the center of the center rod 1. The moving claw in the telescopic component 1 22 is fixedly connected to the corresponding inner clamping block 21 and drives the inner clamping block 21 to move along the radial direction of the center rod 1. The moving claw in the telescopic component 2 25 is fixedly connected to the corresponding outer clamping block 24 and drives the outer clamping block 24 to move along the radial direction of the center rod 1. The structures of the fixing mechanism 1 2 and the fixing mechanism 2 3 are the same, but the telescopic component 1 22 and the telescopic component 2 25 in the fixing mechanism 1 2 are fixedly connected to the center rod 1, and the telescopic component 1 22 and the telescopic component 2 25 in the fixing mechanism 2 3 are slidably connected to the center rod 1.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The left and right adjustment mechanism 4 includes a fixing plate 41 fixedly connected to the right end of the center rod 1, the top of the fixing plate 41 is threadedly connected to a threaded rod 42 located above the center rod 1, and the left end of the threaded rod 42 is rotatably connected to the right side of the telescopic component 25 in the fixing mechanism 2 3.

[0039] In the initial state, the distance between the fixing mechanism 1 2 and the fixing mechanism 2 3 is greater than the length of the cylinder, and the distances between the inner clamping block 21 and the outer clamping block 24 and the axis of the center rod 1 are both smaller than the inner diameter of the cylinder. When in use, the center rod 1 is moved by the existing moving mechanism, and one end of the center rod 1 is passed through the inside of the cylinder, so that the fixing mechanism 1 2 and the fixing mechanism 2 3 are distributed on the left and right sides of the cylinder, and then the corresponding outer clamping block 24 is driven to move outwards by the telescopic component 2 25, so that the distance between the outer clamping block 24 and the axis of the center rod 1 is greater than the inner diameter of the cylinder. The outer diameter of the cylinder is measured, and then the fixing mechanism 23 is pushed close to the fixing mechanism 1 2 by rotating the threaded rod 42, so that the inner clamping block 21 and the outer clamping block 24 are moved to the inner and outer sides of the cylinder respectively, and then the inner clamping block 21 is driven to move outward by the telescopic component 1 22, so that the inner clamping block 21 is clamped on the inner wall of the cylinder, and then the outer clamping block 24 is driven to move inward by the telescopic component 25, so that the outer clamping block 24 is clamped on the outer wall of the cylinder, and the inner and outer sides of the cylinder are double clamped. At this point, the entire device is pre-fixed on the cylinder and is coaxial with the cylinder.

[0040] See also Figure 1 and Figure 3The support assembly 23 includes an outer rod 231 and an inner rod 232 which are slidably sleeved together. The outer rod 231 is provided with an anti-return component 233 to prevent the inner rod 232 from sliding into the inner portion of the outer rod 231. The ends of the outer rod 231 and the inner rod 232 facing each other are fixedly connected to the corresponding inner clamping block 21. It should be noted that the three moving claws on the telescopic assembly 1 22 and the telescopic assembly 2 25 are distributed in an equilateral triangle.

[0041] When the inner clamping block 21 moves outward, the inner clamping block 21 will drive the corresponding outer sleeve rod 231 and inner sleeve rod 232 to move outward. At this time, the inner sleeve rod 232 will slide out from the outer sleeve rod 231. The anti-return component 233 is used to prevent the inner sleeve rod 232 from sliding back into the inner sleeve rod 231. The outer sleeve rod 231 and the inner sleeve rod 232 are used to support the two adjacent inner clamping blocks 21. The three supporting components 23 form a triangular structure to improve the firmness of the inner clamping block 21 clamping the cylinder body.

[0042] See also Figure 1 and Figure 4 The locking assembly 26 includes an insertion rod 261 fixedly connected to the side of the outer clamping block 24 close to the axis of the center rod 1, and a ring 262 is fixedly connected to the side of the inner clamping block 21 close to the corresponding moving claw in the telescopic assembly 25. The end of the insertion rod 261 close to the corresponding inner clamping block 21 is plugged into the ring 262, and an anti-return component 263 is installed on the ring 262 to prevent the insertion rod 261 from sliding to the side away from the axis of the center rod 1.

[0043] See also Figure 1 , Figure 3 , Figure 4 and Figure 5The anti-return component 263 includes a square tube 2631 fixedly mounted on the outer wall of the collar 262, a baffle 2632 fixedly connected to the interior of the square tube 2631, a movable rod 2633 slidably mounted on the middle part of the baffle 2632 along the length direction of the square tube 2631, a wedge block 2634 fixedly connected to the side of the movable rod 2633 close to the corresponding insertion rod 261, an inclined surface of the wedge block 2634 close to the end of the insertion rod 261 is inclined in a direction away from the outer clamping block 24, and a return spring 263 fixedly connected between the wedge block 2634 and the baffle 2632 and sleeved on the outside of the movable rod 2633 5. The end of the movable rod 1 2633 away from the insertion rod 261 is rotatably connected to the pull rod 2636. The end of the square tube 2631 away from the ring 262 is provided with a limit groove 1 2637 and a limit groove 2638 which are perpendicular to each other and match the pull rod 2636. The side of the insertion rod 261 close to the square tube 2631 is provided with a plurality of wedge-shaped grooves 2639 which match the wedge block 2634 and are evenly spaced along the length direction of the insertion rod 261. The difference between the depth of the limit groove 1 2637 and the limit groove 2 2638 is equal to the depth of the wedge-shaped groove 2639. The anti-return component 1 233 has the same structure as the anti-return component 2 263.

[0044] See also Figures 1 to 5 When the outer clamping block 24 moves inward, the end of the insertion rod 261 close to the axis of the center rod 1 is inserted into the inside of the collar 262. When the insertion rod 261 moves inward with the outer clamping block 24, the inclined surface of the wedge-shaped groove 2639 pushes the inclined surface of the wedge-shaped block 2634, causing the wedge-shaped block 2634 to move away from the insertion rod 261. The wedge-shaped block 2634 will not prevent the insertion rod 261 from moving inward. At this time, the return spring 2635 is compressed, but the pull rod 2636 will not move out of the inside of the limit groove 2637. After the block 21 and the outer clamping block 24 are clamped on the inner and outer sides of the cylinder, the insertion rod 261 cannot move further inward. At this time, the rebound force of the reset spring 2635 is used to push the wedge block 2634 into the corresponding wedge groove 2639, and the wedge block 2634 is used to limit the wedge groove 2639 to prevent the insertion rod 261 from moving in the opposite direction. Similarly, the anti-return component 233 prevents the inner sleeve rod 232 from sliding in the opposite direction into the outer sleeve rod 231, thereby fixing the extended length of the inner sleeve rod 232 and the outer sleeve rod 231.

[0045] When the restriction of the anti-return component 263 on the insertion rod 261 and the ring 262 is to be released, the movable rod 1 2633 is driven to move away from the insertion rod 261 by pulling the pull rod 2636 until the pull rod 2636 moves out from the inside of the limiting groove 1 2637, and then the pull rod 2636 is rotated ninety degrees so that the pull rod 2636 is snapped into the limiting groove 2638, preventing the return spring 1 2635 from pushing the wedge block 2634 close to the wedge groove 2639. At this time, the wedge block 2634 is completely separated from the wedge groove 2639 and no longer restricts the movement of the insertion rod 261. At this time, the outer clamping block 24 can drive the insertion rod 261 to move outward, thereby releasing the clamping of the cylinder by the outer clamping block 24.

[0046] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 The angle limiting component includes an angle line 62 opened on the outer ring wall of the turntable 61, a rotating ring 63 located on the right side of the angle line 62 is rotatably connected to the outer ring wall of the turntable 61, a fixed block 64 located at the zero scale line of the angle line 62 is fixedly connected to the outer ring wall of the turntable 61, a movable block 65 matched with the fixed block 64 is fixedly connected to the outer ring wall of the rotating ring 63, and the movable block 65 is connected to the turntable 61 by bolts, a stopper 66 located between the fixed block 64 and the movable block 65 and matched with both the fixed block 64 and the movable block 65 is rotatably installed on the outer ring wall of the telescopic component 22, and a positioning component 1 67 and a positioning component 2 68 for locking the stopper 66 and the turntable 61 respectively are installed on the telescopic component 22.

[0047] When in use, before the device is installed on the cylinder, the angle R1 between the center of the cylinder and the line connecting two adjacent reinforcing ribs is calculated according to the number of reinforcing ribs that need to be welded in the cylinder, and then the rotating ring 63 is rotated to drive the movable block 65 to rotate, so that the movable block 65 rotates to the same angle value as R1 on the angle line 62, and then the bolts are tightened to fix the movable block 65. In the initial state, the stop block 66 conflicts with the fixed block 64.

[0048] When welding the reinforcing ribs, the welding mechanism 7 first performs compression welding on the first reinforcing rib, then releases the positioning of the stopper 66 by the positioning component 1 67, then rotates the stopper 66 counterclockwise so that the stopper 66 conflicts with the movable block 65, and then the positioning component 1 67 positions the stopper 66 again, then releases the fixing of the positioning component 2 68 to the turntable 61, and then drives the turntable 61, the rotating drum 5 and the welding mechanism 7 to rotate counterclockwise by the driving motor 69, and the turntable 61 drives the fixed block 64 and the movable block 65 to rotate synchronously so that the fixed block 64 conflicts with the stopper 66 again. At this time, the rotation angle of the welding mechanism 7 is equal to R1, so that the welding mechanism 7 is aligned with the position where the next reinforcing rib needs to be welded, and after welding the next reinforcing rib, the welding mechanism 7 is rotated at a fixed angle by repeating the above steps, and the subsequent reinforcing ribs are positioned and welded in turn to ensure that the reinforcing ribs are evenly distributed circumferentially and improve the welding quality of the entire cylinder.

[0049] See also Figure 6 , Figure 7 and Figure 8 The positioning component 67 includes a mounting ring 671 rotatably mounted on the outer ring wall of the telescopic component 22, a stopper 66 is fixedly mounted on the right side of the mounting ring 671, and a plurality of limiting holes 672 are evenly opened on the mounting ring 671 in a circumferential direction. A fixing sleeve 673 is fixedly mounted on the outer ring wall of the telescopic component 22, and a movable rod 674 is slidably mounted on the fixing sleeve 673 through the front and rear sides, and the rear end of the movable rod 674 is plugged into the corresponding limiting hole 672, and a blocking piece 675 located between the fixing sleeve 673 and the mounting ring 671 is fixedly connected to the movable rod 674, and a return spring 676 arranged on the outside of the movable rod 674 is fixedly connected between the fixing sleeve 673 and the blocking piece 675. The positioning component 68 has the same structure as the positioning component 67, but the mounting ring 671 in the positioning component 68 is fixedly mounted on the turntable 61.

[0050] When the stop block 66 is to be rotated, first pull the corresponding movable rod 2 674 forward, then the return spring 2 676 will be compressed, and the rear end of the movable rod 2 674 will separate from the limiting hole 672 to release the positioning of the mounting ring 671 and the stop block 66, then rotate the mounting ring 671 and the stop block 66 until the stop block 66 conflicts with the movable block 65, then release the movable rod 2 674, and use the rebound force of the return spring 2 676 to push the movable rod 2 674 into the corresponding limiting hole 672, and fix the position of the mounting ring 671 and the stop block 66 again. Similarly, when the turntable 61 is to be rotated, first release the fixation of the turntable 61 by the positioning component 2 68, and after the turntable 61 drives the fixed block 64 to rotate synchronously until the fixed block 64 conflicts with the stop block 66 again, the positioning component 2 68 re-fixes the turntable 61.

A clamping assembly 73 for clamping the reinforcing rib is installed at the bottom of the mounting frame 71. Welding guns 74 are symmetrically slidably installed on the front and rear sides of the mounting frame 71. A moving assembly 75 that drives the welding gun 74 to move left and right is installed on the mounting frame 71.

[0052] See also Figure 1 and Fig. 9 The clamping assembly 72 includes a mounting seat 721 fixedly connected to the top of the mounting frame 71, and the top of the mounting seat 721 is rotatably connected to two diagonal support rods 722 symmetrically distributed in the front and rear directions, and the bottom of the diagonal support rods 722 is installed with gears, and the front and rear gears are meshed with each other. A bidirectional screw drive module 723 that drives the tops of the front and rear diagonal support rods 722 to move synchronously in the opposite directions is fixedly installed on the mounting plate, and the left and right bidirectional screw drive modules 723 are connected by a pulley assembly. It should be noted that the bidirectional screw drive module 723 belongs to the existing structure, and the screw in the bidirectional screw drive module 723 is a screw with two threaded sections with opposite rotation directions, wherein the screw in the bidirectional screw drive module 723 is connected to the existing drive source, and the bidirectional screw drive module 723 can make the tops of the front and rear diagonal support rods 722 move toward or away from each other.

[0053] See also Figure 1 , Fig. 9 and Fig.11 The moving assembly 75 includes a connecting plate 1 751 which is slidably mounted at the lower end of the mounting frame 71, two welding guns 74 are fixedly mounted at the front and rear ends of the connecting plate 1 751, and a one-way screw driving module 752 which drives the connecting plate 1 751 to move left and right is mounted on the mounting frame 71. Two guide rails 753 which are symmetrically distributed front and back are fixedly connected to the top of the mounting frame 71, and a connecting plate 2 754 is slidably mounted on the guide rails 753, and one end of the connecting plate 2 754 which is away from the corresponding guide rail 753 is fixedly connected to the corresponding welding gun 74. It should be noted that the one-way screw driving module 752 belongs to the prior art, and the screw in the one-way screw driving module 752 is a screw for setting a single-segment thread segment, and one end of the screw is connected to the existing driving source, and the one-way screw driving module 752 can drive the connecting plate 1 751 to move left or right.

[0054] See also Figure 1 , Fig. 9 , Fig.10 and Fig.11 The clamping assembly 73 includes a fixed clamp 731 fixedly installed at the bottom of the mounting frame 71, and a movable clamp 732 matching with the fixed clamp 731 is hinged on the right side, and the front and rear sides of the fixed clamp 731 are connected and locked with the movable clamp 732 through a screw and nut assembly 733.

[0055] See also Figure 1 , Fig. 9 , Fig.10 and Fig.11 When the reinforcing rib is to be welded, the fixed clamp 731 and the movable clamp 732 are first used to clamp the reinforcing rib. By loosening the screw nut assembly 733, the movable clamp 732 can be rotated counterclockwise to a certain angle. Then, the reinforcing rib is inserted between the fixed clamp 731 and the movable clamp 732. Then, the screw nut assembly 733 is re-tightened to make the movable clamp 732 rotate clockwise and clamp the reinforcing rib together with the fixed clamp 731.

[0056] Then, the top ends of the front and rear diagonal support rods 722 are driven to move toward or away from each other through the bidirectional screw drive module 723. When the top ends of the front and rear diagonal support rods 722 move toward each other, the diagonal support rods 722 push the mounting frame 71 and the clamping assembly 73 to move in a direction away from the axis of the cylinder, so that the clamping assembly 73 presses the reinforcing rib against the inner wall of the cylinder. In the initial state, the welding gun 74 is located at the left end of the mounting frame 71, and the welding gun 74 is aimed at the fitting position between the reinforcing rib and the inner wall of the cylinder. The connecting plate 1 751 is driven from left to right along the reinforcing rib by the unidirectional screw drive module 752. The welding gun 74 welds the reinforcing rib to the cylinder during the movement. During the movement of the welding gun 74, a triangular structure is formed between the connecting plate 1 751, the guide rail 753, the connecting plate 2 754, and the welding gun 74, which improves the stability of the welding gun 74 during mobile welding, thereby improving the quality of the reinforcing rib welding.

[0057] After welding is completed, by loosening the screw nut assembly 733 (the screw nut assembly 733 is located outside the cylinder), the movable clamp 732 is rotated counterclockwise by a certain angle and the clamping of the reinforcing rib is loosened. Then, the bidirectional screw drive module 723 drives the tops of the two diagonal support rods 722 to move away from each other, and the diagonal support rods 722 drive the mounting frame 71 and the clamping assembly 73 to move in a direction close to the axis of the cylinder, so that the fixed clamp 731 and the movable clamp 732 leave the welded reinforcing rib. After that, when the rotating cylinder 5 drives the welding mechanism 7 to rotate to the next welding position, the above steps are repeated to weld the subsequent reinforcing ribs.
