Description

Technical Field

[0001] This utility model relates to the field of container processing technology, specifically to a side panel straightening device. Background Technology

[0002] Container side panels are usually welded together from multiple side panel units. Due to the long weld seams, after welding, the welding stress often causes outward camber deformation at the weld joint of two side panel units. Therefore, after welding, it is necessary to straighten the deformed areas.

[0003] Chinese Patent No. CN202121028228.3 discloses a container side panel straightening device. The device uses multiple pressure plates mounted on a lifting frame, which are arranged along the length of the frame. A straightening station is formed at the position below each pressure plate on the frame, so as to simultaneously apply pressure to multiple welds on the container side panel. Through a single pressing action, all welds of the container side panel are straightened. Furthermore, the container side panels are transported by a conveying component, which enables continuous straightening of multiple container side panels, thereby improving the efficiency of container side panel straightening.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0005] The device uses a lifting frame to directly drive the pressure plate to straighten the side plate. Since the lifting frame and the pressure plate are only connected by a few connecting frames, the pressure applied by the pressure plate to the weld of the side plate is different, which affects the straightening effect.

[0006] Therefore, providing a side plate straightening device that can reciprocate and press the side plate weld seam at various points to improve the straightening effect is a problem that this utility model urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the shortcomings of existing devices that directly drive the pressure plate to straighten the side plate via a lifting frame. Because the lifting frame and pressure plate are connected only by several connecting frames, the pressure applied by the pressure plate to different parts of the side plate weld varies, affecting the straightening effect. Therefore, this invention provides a side plate straightening device that can reciprocate and press various parts of the side plate weld to improve the straightening effect.

[0014] Preferably, the second driving mechanism includes: a rotating roller, a transmission wheel, a second transmission belt, a first connecting rod, a second connecting rod, and a second driving assembly. The rotating roller is rotatably disposed at the bottom of the frame, and a plurality of transmission wheels are coaxially spaced on its roller body.

[0016] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application uses a conveying mechanism to move the weld seam of the side plate to be straightened to the gap between the upper and lower pressure blocks. Then, the second drive mechanism is activated to drive the lower and upper pressure blocks to move synchronously to press the weld seam of the side plate to be straightened.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0033] Reference Figure 1 , Figure 6 , Figure 7 and Figure 9 A side plate straightening device, the device comprising: a conveying mechanism 1, a frame 2, a lower pressing block 3, an upper pressing block 4, a moving frame 5, a first driving mechanism 6, and a second driving mechanism 7. A plurality of frames 2 are spaced across the upper part of the conveying mechanism 1. The frames 2 are provided with lower pressing blocks 3 and upper pressing blocks 4 that can reciprocate relative to each other in a vertical direction from top to bottom. The second driving mechanism 7 is located at the bottom of the frames 2 and can drive each lower pressing block 3 and upper pressing block 4 to reciprocate relative to each other. The moving frame 5 is provided at the bottom of the lower pressing block 3 that can reciprocate along the length direction of the lower pressing block 3 through the first driving mechanism 6, and a straightening wheel 501 is provided at its bottom.

[0034] This application uses a conveying mechanism 1 to move the weld seam of the side plate to be straightened to the gap between the upper pressure block 4 and the lower pressure block 3. Then, the second drive mechanism 7 is activated, which drives the lower pressure block 3 and the upper pressure block 4 to move synchronously to press the weld seam of the side plate to be straightened. Next, the first drive mechanism 6 is activated to drive the moving frame 5 to move back and forth along the weld seam. During this process, the straightening wheel 501 contacts the side plate, thereby applying straightening pressure to the protruding part of the weld seam. The duration and pressure can be adjusted by the control system. After a certain period of straightening, the shape of the weld seam of the side plate to be straightened will be as flat as other parts. After straightening is completed, the second drive mechanism 7 drives the lower pressure block 3 and the upper pressure block 4 to move synchronously to release the straightened side plate so that the conveying mechanism 1 can transport the side plate out. This straightening method can reciprocate and press all parts of the side plate weld seam to improve the straightening effect.

[0035] Reference Figures 7-9 The movable frame 5 is provided with a limiting slider 502 above it, and the bottom of the pressing block 3 is provided with a limiting groove 301 that is adapted to the limiting slider 502.

[0036] The movable frame 5 of this application is reciprocally mounted in the limiting slide groove 301 via the limiting slider 502 to ensure that the movable frame 5 can drive the straightening wheel 501 to move back and forth stably along the weld without deviation.

[0037] Reference Figure 8 The first driving mechanism 6 includes a first rotary motor 601 and a lead screw 602. The first rotary motor 601 is mounted on the lower pressure block 3, and its output shaft is coaxially mounted with the lead screw 602. The lead screw 602 is horizontally threaded through the movable frame 5 and is rotatably mounted on the lower pressure block 3.

[0038] This application achieves straightening by starting the first rotary motor 601 to drive the lead screw 602 to rotate, thereby driving the moving frame 5 to move back and forth, which in turn drives the straightening wheel 501 to reciprocate and roll along the weld seam in a stable manner; due to the design of the lead screw 602 inside the lower pressure block 3, it is hidden in the structure, which saves space, reduces external interference, and improves the overall stability of the equipment.

[0039] Reference Figure 2 and Figure 3 The conveying mechanism 1 includes a first transmission belt 101 and a first drive assembly 102. The first transmission belt 101 is tractably disposed below the frame 2 via the first drive assembly 102, and its belt body is provided with a plurality of straightening holes 10101 that are adapted to the straightening wheel 501.

[0040] In this application, the weld seam of the side plate to be straightened is placed at the straightening hole 10101 on the first transmission belt 101. Then, as the transmission belt moves cyclically, the weld seam of the side plate to be straightened is fed between the lower pressure block 3 and the upper pressure block 4 through the conveying mechanism 1, thereby ensuring the continuity of the straightening work.

[0041] Reference Figure 3 The first transmission belt 101 has limiting blocks 10102 on its opposite sides that are adapted to the straight side plate to be straightened.

[0042] This application employs a design to prevent the side plate to be straightened from shifting during transport, thus affecting the straightening effect. Furthermore, anti-slip textures on the transmission belt further prevent misalignment of the side plate, ensuring the straightening effect is maintained. During straightening, the limiting block 10102 and the anti-slip textures on the transmission belt not only keep the side plate stable but also allow the straightening wheel 501 to contact the deformed portion of the side plate weld at the optimal angle and height, ensuring the effectiveness of the straightening operation. This combination significantly improves the straightening effect, ensuring the side plate weld returns to a flat state.

[0043] Reference Figure 7 The lower pressure block 3 has a first pressing block 302 on each side of the bottom of the side plate weld to be straightened. The lower surface of the first pressing block 302 is flush with the bottom side of the straightening wheel 501. The upper surface of the upper pressure block 4 has a second pressing block 401 that is adapted to the straightening hole 10101.

[0044] The first clamping block 302 of this application can cooperate with the upper clamping block 4 to fix the side plate, thereby further preventing the side plate from shifting during the straightening process. The second clamping block 401 can effectively support the straightening wheel 501 and enhance the straightening force.

[0045] Reference Figure 4 and Figure 5 The second driving mechanism 7 includes: a rotating roller 701, a transmission wheel 702, a second transmission belt 703, a first connecting rod 704, a second connecting rod 705, and a second driving assembly 706. The rotating roller 701 is rotatably mounted at the bottom of the frame 2, and a plurality of transmission wheels 702 are coaxially spaced on its roller body. The two ends of the second transmission belt 703 are respectively sleeved on the transmission wheels 702 of the adjacent rotating roller 701. The second driving assembly 706 is mounted on one side of any rotating roller 701 and can drive the rotating roller 701 to reciprocate. The two ends of the rotating roller 701 are respectively provided with a linkage frame 70101. The two ends of the linkage frame 70101 are respectively hinged to one end of the first connecting rod 704 and one end of the second connecting rod 705. The other end of the first connecting rod 704 is hinged to one side of the lower pressure block 3, and the other end of the second connecting rod 705 is hinged to one side of the upper pressure block 4.

[0046] This application activates the second drive assembly 706 to drive the rotating roller 701 to rotate, and the linkage frame 70101 will also move accordingly. Thus, the first linkage rod 704 and the second linkage rod 705 drive the lower pressure block 3 and the upper pressure block 4 to move synchronously towards each other, thereby pressing the weld seam of the side plate to be straightened. At the same time, due to the cooperation of the second transmission belt 703 and the transmission wheel 702, each rotating roller 701 can be driven to rotate synchronously, thereby straightening multiple weld seams of the side plate to be straightened.

[0047] Reference Figure 5 The second drive assembly 706 includes a drive wheel 70601, a strip frame 70602, a second rotary motor 70603, and a drive rod 70604. The drive wheel 70601 is rotatably mounted on one side of the rotating roller 701. The strip frame 70602 is mounted on one side of the drive wheel 70601. The second rotary motor 70603 is mounted on one side of the drive wheel 70601, and its output shaft is coaxially mounted with the drive rod 70604. The outer end of the drive rod 70604 is provided with a snap-fit ​​post adapted to the strip frame 70602. The two ends of any second transmission belt 703 are respectively sleeved on the drive wheel 70601 and the adjacent transmission wheel 702.

[0048] This application starts the second rotary motor 70603 to drive the drive rod 70604 to rotate, thereby driving the drive wheel 70601 to reciprocate through the cooperation of the snap-fit ​​column and the strip frame 70602, and then driving the adjacent rotating roller 701 to reciprocate through the second transmission belt 703, and driving each rotating roller 701 to reciprocate synchronously through other second transmission belts 703.

[0049] In use, the device provided by this utility model moves the weld seam of the side plate to be straightened to the gap between the upper pressure block 4 and the lower pressure block 3 via the conveying mechanism 1. Then, the second drive mechanism 7 is activated, which drives the lower pressure block 3 and the upper pressure block 4 to move synchronously to press the weld seam of the side plate to be straightened. Next, the first drive mechanism 6 is activated to drive the moving frame 5 to move back and forth along the weld seam. During this process, the straightening wheel 501 contacts the side plate, thereby applying straightening pressure to the protruding part of the weld seam. The duration and pressure can be adjusted by the control system. After a certain period of straightening, the shape of the weld seam of the side plate to be straightened will be as flat as other parts. After straightening is completed, the second drive mechanism 7 drives the lower pressure block 3 and the upper pressure block 4 to move synchronously to release the straightened side plate so that the conveying mechanism 1 can transport the side plate out. This straightening method can reciprocate and press all parts of the side plate weld seam to improve the straightening effect.
