Description

Technical Field

[0001] The utility model relates to the field of aluminum plate production equipment, in particular to a joint device used in a color aluminum roller coating production line. Background Art

[0002] The color-coated aluminum roller coating production line is a production line specifically used for producing color-coated aluminum plates. It uses a continuous roller coating method to apply multiple layers of organic coatings on the surface of the aluminum plates to form a composite material. The joint device is an important component of the color-coated aluminum roller coating production line. It is mainly used to complete the joint work of the front and rear sets of aluminum plates after the aluminum plates are unrolled, thereby ensuring the continuous operation of the production line and avoiding production interruptions.

[0003] Existing joint devices usually include a clamping mechanism and a welding mechanism. When two sets of aluminum plates need to be joined, the ends of the two sets of aluminum plates are moved to the bottom of the clamping mechanism, and the ends of the two sets of aluminum plates are first squeezed by the clamping mechanism to make them fit tightly. After squeezing, the ends of the two sets of aluminum plates need to be moved to the bottom of the welding structure, and the two sets of aluminum plates are welded through the welding structure to complete the joining of the two sets of aluminum plates.

[0004] However, when the ends of the two sets of aluminum plates are squeezed by the clamping mechanism, since dust and fine particulate impurities are usually attached to the surface of the aluminum plates, these dust and fine particulate impurities may remain in the gap between the ends of the two sets of aluminum plates during extrusion, which may cause these dust and fine particulate impurities to affect the quality of welding during subsequent welding, thereby reducing the strength of the weld between the two sets of aluminum plates.

[0033] Reference Figure 1-8 The top of spring 16 is fixedly connected with the top of storage groove 8, and the bottom of spring 16 is fixedly connected with the top of storage groove 8. The bottom end of spring 16 is fixedly connected with the top of storage groove 8, and the bottom end of spring 16 is fixedly connected with the top of storage groove 8. The blower 7 is provided with an air outlet 9 on the side of the blower 7 adjacent to the pressing rod 3. The bottom end of the blower 7 is provided with an anti-pressure plate 10. The side of the installation box 5 away from the pressing rod 3 is provided with a limit block 11, and the inner side of the pressing mechanism is provided with a sliding groove 12 for the movement of the limit block 11. The dust and fine particle impurities on the surfaces of the two sets of aluminum plates 34 are cleaned by the blower 7 to prevent them from remaining in the gap between the ends of the two sets of aluminum plates 34, thereby improving the quality of subsequent welding.

[0034] The clamping mechanism includes a mounting frame 13 and multiple telescopic cylinders 14. There are multiple telescopic cylinders 14. The two ends of the bottom of the mounting frame 13 are fixedly connected to the two sides of the processing base 1 respectively. One end of the multiple telescopic cylinders 14 is fixedly connected to the top of the inner side of the mounting frame 13, and the output end of the telescopic cylinder 14 is fixedly connected to the top of the clamping rod 3. The multiple telescopic cylinders 14 drive the clamping rod 3 to move toward the surface of the two groups of aluminum plates 34, thereby causing the clamping rod 3 to squeeze the ends of the two groups of aluminum plates 34.

[0035] One side of the processing base 1 is provided with a driving component 15 for adjusting the welding mechanism 2. The driving component 15 includes a fixed rod 16, a motor 17 and a threaded rod 18. One side of the fixed rod 16 is fixedly connected to one side of the processing base 1. The top of the fixed rod 16 is provided with a movable groove 19 for the welding mechanism 2 to move. The two ends of the threaded rod 18 are respectively rotatably connected to the two sides inside the movable groove 19. One end of the fixed rod 16 is provided with a mounting plate 20. The bottom of the motor 17 is fixedly connected to the top of the mounting plate 20. The output end of the motor 17 passes through one end of the fixed rod 16 and is fixedly connected to one end of the threaded rod 18. The threaded rod 18 is driven by the motor 17 to rotate. Since the bottom of the moving rod 21 is sleeved on the outside of the threaded rod 18, and the moving rod 21 is threadedly connected to the outside of the threaded rod 18, when the threaded rod 18 moves and rotates, the moving rod 21 will be driven to move along the threaded rod 18. The movement of the moving rod 21 drives the support rod 22 and the welding head 27 to move on the top of the processing base 1;

[0036] The bottom of the welding mechanism 2 is sleeved on the outside of the threaded rod 18, and the welding mechanism 2 is threadedly connected to the outside of the threaded rod 18. The welding mechanism 2 includes a moving rod 21, a support rod 22, a second motor 23 and a moving block 24. The bottom of the moving rod 21 is sleeved on the outside of the threaded rod 18, and the moving rod 21 is threadedly connected to the outside of the threaded rod 18. The bottom of the support rod 22 is fixedly connected to the top of the moving rod 21. A groove 25 is provided at the bottom of the support rod 22 for the movement of the moving block 24. One end of the second motor 23 is fixedly connected to one end of the support rod 22. The output end of the second motor 23 passes through one end of the support rod 22 and extends into the groove 25. The output end of the second motor 23 is provided with a second threaded rod 26. The end of the second threaded rod 26 away from the second motor 23 is rotatably connected to the inner side of the groove 25. The moving block 24 is sleeved on the outside of the second threaded rod 26. The moving block 24 is threadedly connected to the outside of the second threaded rod 26. A welding head 27 is provided at the bottom of the moving block 24.

[0037] When the cam 32 is released, the cam 32 is released, and the push rod 30 is pushed back to the left and right sides of the cam 32 so that the cam 32 can move upward.

[0038] Working principle: When it is necessary to perform seam joining work on two groups of aluminum plates 34, the ends of the two groups of aluminum plates 34 are moved to the bottom of the pressing rod 3, and the pressing rod 3 is driven by multiple telescopic cylinders 14 to move toward the surface of the two groups of aluminum plates 34, so that the pressing rod 3 squeezes the ends of the two groups of aluminum plates 34. Since the blower 7 is provided with an air outlet 9 at the bottom end of one side near the pressing rod 3, before the pressing rod 3 extrude the two groups of aluminum plates 34, the blower 7 will clean the dust and fine particulate impurities on the surface of the two groups of aluminum plates 34 to prevent them from remaining in the gap between the ends of the two groups of aluminum plates 34, thereby improving the quality of subsequent welding and the strength and toughness of the weld between the two groups of aluminum plates 34. At the same time, the clean surface of the aluminum plate 34 can ensure the close connection between the two groups of aluminum plates 34, thereby improving the pressing effect.

[0039] When the pressing rod 3 moves, the installation box 5 and the blower 7 are driven to move. When the anti-pressure plate 10 provided at the bottom of the blower 7 contacts the top of the processing base 1, the anti-pressure plate 10 and the blower 7 are subjected to an upward extrusion force, thereby causing the blower 7 to move toward the inside of the storage groove 8 and squeeze the spring 1 6. When the bottom of the pressing rod 3 contacts the surface of the aluminum plate 34, the air blowing port opened on one side of the blower 7 will be blocked by one end of the pressing rod 3, thereby preventing the air blowing port from continuing to blow toward the surface of the aluminum plate 34, thereby preventing the blower 7 from blowing excessively and causing unnecessary damage to the surface of the aluminum plate 34.

[0040] By means of the limit block 11 provided on one side of the installation box 5 and the sliding groove 12 provided on the inner side of the installation frame 13, when the installation box 5 moves, the limit block 11 will be driven to move inside the sliding groove 12. Since the outer side of the limit block 11 fits in with the inner side of the sliding groove 12, the installation box 5 can be prevented from deflecting or shaking during the movement. At the same time, the anti-pressure plate 10 provided at the bottom of the hair dryer 7 prevents the hair dryer 7 from being squeezed and damaged by the processing base 1.

[0041] When welding is required at the ends of the two sets of aluminum plates 34, the ends of the two sets of aluminum plates 34 that have been squeezed are moved to the bottom of the welding head 27, and the motor 23 drives the threaded rod 26 to rotate. Since the moving block 24 is threadedly connected to the outer side of the threaded rod 26, when the threaded rod 26 rotates, the moving block 24 moves along the threaded rod 26. At the same time, because the outer side of the moving block 24 fits into the inner side of the groove 25, the moving block 24 can be prevented from rotating along the movement trajectory of the threaded rod 26. During the movement of the moving block 24, the welding head 27 is driven to move, thereby performing welding work on the ends of the two sets of aluminum plates 34.

[0042] The motor 17 drives the threaded rod 18 to rotate. Since the bottom of the moving rod 21 is sleeved on the outside of the threaded rod 18 and the moving rod 21 is threadedly connected to the outside of the threaded rod 18, when the threaded rod 18 moves and rotates, the moving rod 21 is driven to move along the threaded rod 18. The movement of the moving rod 21 drives the support rod 22 and the top of the welding head 27 processing base 1 to move. The setting of the moving groove 19 can prevent the moving rod 21 from rotating as the threaded rod 18 rotates.

[0043] Pull the limit plate 32 upward, and the extrusion rod 30 will move upward inside the slot 33 through the limit plate 32. When the extrusion rod 30 moves upward, it will drive the spring 2 31 to stretch, and at the same time, the aluminum plate 34 will pass through the bottom of the limit plate 32. Loosen the limit plate 32, and under the action of the rebound force of the spring 2 31, the extrusion rod 30 and the limit plate 32 will be driven to reset, so that the bottom of the limit plate 32 fits with the surface of the aluminum plate 34, and the aluminum plate 34 is limited by the limit plate 32.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
