Description

Technical Field

[0001] This invention belongs to the field of conveyor welding machine technology, specifically, it relates to a welding machine for processing chain conveyors. Background Technology

[0002] A conveyor is a mechanical device that uses continuously moving traction components to uniformly transport materials from loading to unloading points. It is an indispensable core piece of equipment in industrial production, logistics distribution, and warehousing systems. A chain conveyor is a mechanical device that uses a chain as its core traction and load-bearing element. The chain and sprockets mesh to achieve continuous cyclical motion, thus completing the material transport. A welding machine is the core equipment for welding processes, used to join metal materials (such as steel, stainless steel, aluminum alloys, etc.) into a single unit through heating, pressurization, or a combination of both. Essentially, it converts electrical, mechanical, or chemical energy into heat energy, causing the joint to achieve an atomic bond, thus forming a strong welded joint. Chain conveyors require welding machines for welding operations; therefore, a welding machine specifically designed for chain conveyor processing is needed.

[0003] In existing technologies, welding machines used for chain conveyor processing typically involve fixing the chain conveyor frame onto a welding table and then welding it with a welding torch. The frame is a heavy-duty structural component, mainly used to support the weight of the chain, scraper, and materials. It is usually made of medium-thick plates and is typically large in size, needing to withstand various loads such as tension, bending, and torsion. Therefore, multi-layer, multi-pass welding is required when welding the frame. However, welding slag and oxide impurities are easily left behind during welding, reducing the density and load-bearing capacity of the weld. This requires manual shutdown and cleaning of the weld by workers, reducing the welding efficiency of the welding machine and increasing the labor intensity of the workers, thus reducing the effectiveness of the welding machine used for chain conveyor processing. Summary of the Invention

[0004] The purpose of this invention is to provide a welding machine for processing chain conveyors, which solves the technical problems in related technologies where welding slag and oxide impurities are easily left behind during welding, reducing the density and load-bearing capacity of the weld, reducing the welding efficiency of the welding machine, and increasing the labor intensity of the workers.

[0034] Example 1 like Figures 1-4 As shown, a welding machine for processing chain conveyors according to an embodiment of the present invention is illustrated. It includes a movable base 1 and a welding equipment box 2 mounted on the movable base 1. The welding equipment box 2 is equipped with a welding mechanism for welding the chain conveyor. The welding mechanism includes a connecting seat 4 mounted on one side of the welding equipment box 2 and a robotic arm 5 mounted on the connecting seat 4.

The welding mechanism also includes a welding torch 9 detachably mounted on the rotating block 7 and a first quick-release structure 10 connecting the welding torch 9 to the rotating block 7. Two first quick-release structures 10 are symmetrically arranged on the rotating block 7. Another first quick-release structure 10 is equipped with a rotating base 11. A fixed base 12 is rotatably mounted on the rotating base 11. A grinding structure 13 is movably mounted on the fixed base 12. The grinding structure 13 can grind the welded area to facilitate the next welding operation.

[0035] Furthermore, the welding equipment box 2 is moved to the frame to be welded by the movable seat 1, and the welding gun 9 is moved to the welding position by the robotic arm 5 so that the welding gun 9 can perform welding work. After the initial welding, after the weld cools down, the first rotary motor 8 is started to drive the rotating block 7 to rotate, so that the rotating block 7 drives the first quick-release structure 10 to rotate. The two first quick-release structures 10 adjust the positions of the welding gun 9 and the grinding structure 13 respectively, move the grinding structure 13 to the weld, start the grinding structure 13, and grind the welding slag, spatter and protrusions on the surface of the weld to make the weld surface smooth. Then the welding gun 9 is controlled to perform welding again.

[0036] As a specific example, such as Figure 2 and Figure 3 As shown, the first quick-release structure 10 includes a first connecting block 14 symmetrically arranged on the rotating block 7 and a first connecting member 15 fixedly connected to the first connecting block 14. The first connecting member 15 has a first connecting groove that fits with the first connecting block 14.

[0037] Further, the first connecting block 14 is removed from the first connecting groove, the first connecting block 14 is separated from the first connecting member 15, and the welding gun 9 or the grinding structure 13 is disassembled and maintained.

[0038] As a specific example, such as Figure 2 and Figure 4 As shown, the welding mechanism also includes a connecting sleeve 16 for fixing the welding gun 9. Two first connecting parts 15 are fixed to the connecting sleeve 16 and the rotating seat 11 respectively. A rotating rod 17 is rotatably provided on the rotating seat 11 and is perpendicularly connected to the fixed seat 12. A second rotary motor 18 is provided on the side of the rotating seat 11 away from the fixed seat 12 to control the rotation of the rotating rod 17. The second rotary motor 18 and the rotating rod 17 cooperate to adjust the angle of the grinding structure 13.

[0039] Furthermore, the welding torch 9 is fixed to the connecting sleeve 16, and the first connecting block 14 and the first connecting piece 15 cooperate to fix the connecting sleeve 16 to the rotating block 7. The second rotating motor 18 is started to drive the rotating rod 17 to rotate, so that the rotating rod 17 drives the fixed seat 12 to rotate.

[0040] As a specific example, such as Figure 2 and Figure 4 As shown, a fixing plate 19 for mounting the grinding structure 13 is movably provided on the side of the fixing base 12 away from the rotating rod 17. The welding mechanism also includes a first main gear 20 rotatably installed inside the fixing base 12 and controlling the stable movement of the fixing plate 19, and a first guide rod 21 vertically inserted into the fixing plate 19. The fixing plate 19 has a first guide hole that matches the first guide rod 21 and a first groove that matches the first main gear 20. A first moving rack 22 that meshes with the first main gear 20 is installed in the first groove. The upper end of the fixing base 12 is provided with a first drive motor 23 that is coaxially connected to the first main gear 20, so that the first drive motor 23, the first main gear 20 and the first moving rack 22 cooperate to control the grinding structure 13 to adjust its position through the fixing plate 19.

[0041] Furthermore, the first drive motor 23 is started, which drives the first main gear 20 to rotate, so that the first main gear 20 drives the first moving rack 22 to move, and the first moving rack 22 drives the fixed plate 19 to move on the fixed seat 12, so that the fixed plate 19 drives the grinding structure 13 to adjust its position, and so that the first guide rod 21 moves in the first guide hole.

[0042] As a specific example, such as Figure 2 and Figure 4 As shown, the grinding structure 13 includes a grinding motor 24 detachably mounted on the upper end of the fixed plate 19 and a grinding component 25 disposed on the lower side of the fixed plate 19 and connected to the grinding motor 24.

[0043] Furthermore, the grinding motor 24 is started, which drives the grinding part 25 to rotate through the fixed shaft, so that the grinding part 25 can perform grinding work.

[0044] Example 2 Based on Example 1, referring to Figure 2 - Figure 7 This is the second embodiment of the present invention.

[0045] As a specific example, such as Figure 4 and Figure 5 As shown, the welding mechanism also includes a cooling assembly on the welding equipment box 2 for auxiliary cooling of the chain conveyor. The cooling assembly includes a cooling head 26 connected to the rotating block 7 and an air extraction box 27 on the connecting seat 4. The rotating block 7 is provided with a second quick-release structure 28 for fixing the cooling head 26. One end of the cooling head 26 is provided with a cooling pipe 29 connected to the air extraction box 27. The bottom end of the air extraction box 27 is detachably provided with an air extraction device 30. The air extraction device 30, the air extraction box 27, the cooling pipe 29 and the cooling head 26 work together to provide auxiliary cooling for the welding joint of the chain conveyor, which facilitates the grinding process of the grinding structure 13.

[0046] Furthermore, when cooling the weld, the exhaust device 30 is activated, causing the cooling head 26 to extract air from the weld, thereby accelerating the airflow at the weld, cooling the weld, and introducing the extracted air into the exhaust box 27 through the cooling pipe 29; when the grinding structure 13 generates dust during grinding, the exhaust device 30 is activated, causing the cooling head 26 to introduce the dust into the exhaust box 27 through the cooling pipe 29, reducing dust dispersion.

[0047] As a specific example, such as Figure 2 As shown, the second quick-release structure 28 includes a second connecting block 31 vertically disposed on the rotating block 7 and a second connecting member 32 vertically disposed on the cooling head 26 and threadedly fixed to the second connecting block 31.

[0048] Furthermore, rotating the cooling head 26 causes the second connecting member 32 to rotate, so that the second connecting member 32 is threadedly fixed to the second connecting block 31, thus fixing the cooling head 26 onto the rotating block 7. Conversely, rotating the cooling head 26 removes it from the rotating block 7.

[0049] As a specific example, such as Figure 2 - Figure 3 and Figure 5 As shown, the cooling assembly also includes a connector 36 that connects the cooling pipe 29 to the air extraction box 27 and an air extraction pipe 33 provided on the air extraction device 30. One end of the air extraction pipe 33 extends into the air extraction box 27, and an air inlet is provided on the air extraction pipe 33.

[0050] Furthermore, the air extraction device 30 is activated, so that the air extraction pipe 33 extracts air through the air inlet, thereby performing the air extraction operation.

[0051] As a specific example, such as Figure 5 - Figure 7 As shown, the cooling assembly also includes a filter cartridge 34 rotatably disposed in the suction box 27 and a first scraper 35 symmetrically disposed inside the filter cartridge 34 for cleaning the filter cartridge 34. The suction box 27 has a suction chamber for use with the filter cartridge 34. Both the upper and lower ends of the filter cartridge 34 are inserted into the suction box 27. The suction box 27 has an air guide hole that matches the connector 36. The air guide hole is located inside the filter cartridge 34. The air inlet of the suction pipe 33 is aligned with the filter cartridge 34. The inner wall of the filter cylinder 34 is provided with a through groove for the rotation of the filter cylinder 34. A cleaning roller 37 is symmetrically rotated in the through groove to clean the filter cylinder 34. A cleaning scraper 38 is attached to one side of the cleaning roller 37 to clean the cleaning roller 37. A second scraper 39 for cleaning the filter cylinder 34 is provided in the middle of the through groove. A first discharge groove that works with the through groove is provided at the bottom of the air extraction box 27. A first collection box 40 that is aligned with the first discharge groove is sealed at the bottom of the air extraction box 27.

[0052] Furthermore, when the air extraction device 30 is working, the cooling pipe 29 introduces external air into the air extraction box 27, causing the filter cartridge 34 to filter the air. The filtered air is then discharged through the air extraction device 30. When the filter cartridge 34 rotates, the filter surface of the filter cartridge 34 is adjusted, and the first scraper 35 performs preliminary cleaning on the filter surface of the filter cartridge 34. When the filter cartridge 34 rotates into the through groove, the cleaning roller 37 and the second scraper 39 work together to clean the filter surface of the filter cartridge 34 again, and the cleaning scraper 38 cleans the cleaning roller 37. The cleaned impurities are then introduced into the first collection box 40 through the first discharge chute.

[0053] As a specific example, such as Figure 6 and Figure 7 As shown, the cooling assembly also includes a connecting ring 59 disposed at the upper end of the filter cylinder 34 and a transmission external gear ring 60 disposed outside the connecting ring 59, with a rotating gear 61 meshing on the outer side of the transmission external gear ring 60.

[0054] Furthermore, when the rotating gear 61 rotates, it drives the transmission external gear ring 60 to rotate, which in turn drives the connecting ring 59 to rotate, causing the connecting ring 59 to drive the filter cartridge 34 to rotate in the suction box 27.

[0055] As a specific example, such as Figure 6 and Figure 7As shown, the cooling assembly also includes a first synchronous belt structure 50 that drives the two cleaning rollers 37. The first synchronous belt structure 50 has a triangular structure. The rotating gear 61 is connected to the first synchronous belt structure 50 through a connecting rod. The upper end of the air extraction box 27 is provided with a first synchronous motor 51 that controls the operation of the first synchronous belt structure 50. The first synchronous motor 51 and the first synchronous belt structure 50 cooperate to make the cleaning rollers 37 rotate.

[0056] Furthermore, the first synchronous motor 51 is started, which drives the first synchronous belt structure 50 to rotate, causing the first synchronous belt structure 50 to drive the two cleaning rollers 37 to rotate, and causing the first synchronous belt structure 50 to drive the rotating gear 61 to rotate.

[0057] Example 3 Based on Example 2, referring to Figure 3 and Figure 5 - Figure 10 This is the third embodiment of the present invention.

[0058] As a specific example, such as Figure 3 and Figure 5 As shown, the cooling assembly also includes a second discharge trough located at the bottom of the suction box 27, an external connector 41 located at the bottom of the suction box 27 and aligned and connected to the second discharge trough, and a guide box 42 sealed and connected to the external connector 41. The guide box 42 collects the impurities cleaned by the first scraper 35 through the second discharge trough. The interior of the guide box 42 is provided with a guide cavity with a smooth design and a guide trough connected to the guide cavity. The bottom of the guide box 42 is provided with a second collection box 43 connected to the guide trough.

[0059] Furthermore, when the filter cylinder 34 rotates, the first scraper 35 performs preliminary cleaning on the filter surface of the filter cylinder 34, allowing impurities to enter the guide box 42 through the second discharge chute, and then enter the second collection box 43 through the guide cavity and the guide chute. When large particles of impurities in the cooling pipe 29 enter the suction box 27, the negative pressure suction suddenly decreases, allowing them to enter the guide box 42 through the second discharge chute.

[0060] As a specific example, such as Figure 5 - Figure 6 and Figure 8As shown, the welding mechanism also includes a sealing assembly disposed in the guide box 42 to seal or open the guide channel. The sealing assembly includes several sealing blocks 44 arranged in a circular array and movably disposed in the guide box 42, and a guide strip 45 disposed at the bottom of the sealing blocks 44 and connected to the guide box 42 for guidance. The guide box 42 has a movable groove that cooperates with the sealing blocks 44. The bottom end of the guide strip 45 is provided with a second movable rack 46 and a second transmission gear 47 that controls the movement of the second movable rack 46. The sealing assembly also includes a second main gear 48 coaxially connected to the bottom end of the second transmission gear 47 and a transmission internal gear ring 49 meshing with the second main gear 48. The transmission internal gear ring 49 is rotatably disposed in the guide box 42. The cooperation between the second main gear 48 and the transmission internal gear ring 49 allows the second transmission gear 47 to control several sealing blocks 44 to seal or open the guide channel through the second movable rack 46.

[0061] Furthermore, when the second collection box 43 has collected enough impurities, it is detached from the guide box 42, causing the second main gear 48 to rotate. The second main gear 48 drives the transmission internal gear ring 49 to rotate, causing the transmission internal gear ring 49 to drive several second main gears 48 to rotate synchronously. The rotation of the second main gear 48 drives the second transmission gear 47 to rotate, and the second transmission gear 47 drives the second moving rack 46 to move. The second moving rack 46 drives the guide bar 45 to move, causing the guide bar 45 to drive the sealing block 44 to move, sealing the guide trough. This allows the guide box 42 to temporarily store impurities. The second collection box 43 is then installed on the guide box 42, causing the sealing block 44 to open the guide trough, thus connecting the guide box 42 and the second collection box 43.

[0062] As a specific example, such as Figure 8 As shown, the sealing assembly also includes a second drive motor 52 installed inside the guide box 42 and a second synchronous belt structure 53 connected to the output shaft of the second drive motor 52. One end of the second synchronous belt structure 53 is provided with a first transmission rod coaxially connected to any one of the second main gears 48, so that the second drive motor 52 and the second synchronous belt structure 53 cooperate to control a number of sealing blocks 44 to seal or open the guide trough.

[0063] Furthermore, the second drive motor 52 is started, which drives the second synchronous belt structure 53 to work, so that the second synchronous belt structure 53 drives the second main gear 48 to rotate, and the transmission internal gear ring 49 and the second transmission gear 47 control several sealing blocks 44 to seal or open the guide chute through the second moving rack 46.

[0064] Example 4 Based on Example 3, referring to Figure 8 - Figure 10 This is the fourth embodiment of the present invention.

[0065] As a specific example, such as Figure 8 - Figure 10 As shown, the sealing assembly also includes a bevel gear structure 54 coaxially connected to any one of the second main gears 48 and a third main gear 55 coaxially connected to the bevel gear structure 54. A second transmission rod is provided between the third main gear 55 and the bevel gear structure 54. The sealing assembly also includes a lifting rack 56 meshing with the third main gear 55 and a weight block 57 disposed at the bottom end of the lifting rack 56. The guide box 42 has a moving groove that fits against the lifting rack 56 and the weight block 57. The bottom end of the lifting rack 56 extends to the lower side of the guide box 42. When the second collection box 43 is installed on the guide box 42, the weight block 57 controls the lifting rack. 56 moves upward, thereby enabling the second main gear 48, transmission internal gear ring 49, second transmission gear 47, and second moving rack 46 to control the sealing block 44 to open the guide chute, so that the guide box 42 is connected to the second collection box 43. When the second collection box 43 is removed from the guide box 42, the weight block 57 controls the lifting rack 56 to move downward, and the third main gear 55 and bevel gear structure 54 cooperate to enable the second main gear 48, transmission internal gear ring 49, second transmission gear 47, and second moving rack 46 to control the sealing block 44 to seal the guide chute.

[0066] Furthermore, when the second collection box 43 is installed on the guide box 42, the second collection box 43 presses against the weight block 57, causing the weight block 57 to move upward. The weight block 57 drives the lifting rack 56 to move upward, and the lifting rack 56 drives the third main gear 55 to rotate. The third main gear 55 drives the bevel gear structure 54 to rotate through the second transmission rod, which in turn drives the second main gear 48 to rotate. The second main gear 48 drives the transmission internal gear ring 49 to rotate, which in turn drives several second main gears 48 to rotate synchronously. The rotation of the second main gear 48 drives the second transmission gear 47 to rotate, which in turn drives the second moving rack 46 to move. The second moving rack 46 drives the guide bar 45 to move, which in turn drives the sealing block 44 to move, opening the guide chute and connecting the guide box 42 with the second collection box 43.

[0067] As a specific example, such as Figure 9 As shown, the sealing assembly also includes a second guide hole symmetrically opened on the lifting rack 56 and a second guide rod 3 movably disposed in the second guide hole. The bottom end of the second guide rod 3 is provided with a buffer spring 58 connected to the second guide hole.

[0068] Furthermore, when the weight block 57 moves the lifting rack 56, the second guide rod 3 moves in the second guide hole, causing the buffer spring 58 to extend and retract, thus buffering the lifting rack 56.

[0069] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
