Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to an automatic conveying welding device for freeze-drying bin equipment. Background Art

[0002] The basic principle of freeze-drying is based on the three-state change of water. Under high vacuum conditions, the sublimation principle is used to allow the water in the pre-frozen material to be sublimated directly into water vapor without melting the ice, thereby achieving the purpose of freeze-drying. At present, the structure of most food freeze-drying warehouses is in the shape of a tank, and is made of multi-section cylinders welded together.

[0003] The existing freeze-drying silo cylinder welding work usually adopts the circumferential seam welding technology, that is, the two cylinder welding ends are placed in the circular welding track, and the welding head in the circular track is started to move in a circle to align with the weld seam to complete the welding work of a section of the freeze-drying silo cylinder. This method has high welding efficiency. However, before welding, the two sections of the freeze-drying silo cylinder need to be shape-detected in advance to ensure that the welding contours of the two are consistent, and the welding ends need to be smooth before automatic circumferential seam welding can be performed. At present, the inspection and grinding of the freeze-drying silo cylinder need to be carried out on specific equipment, and the transfer of the cylinder between the equipment is time-consuming and labor-intensive, which greatly reduces the welding efficiency of the freeze-drying silo.

[0030] A telescopic cylinder 29 is fixedly installed at the lower end of the moving block 27. A mounting plate 30 is fixedly connected to the telescopic end of the telescopic cylinder 29. A rubber block 31 is fixedly connected to the lower end of the mounting plate 30. The lower end of the rubber block 31 is an arc-shaped surface for contacting the upper end of the freeze-drying bin cylinder. Two vertical plates 32 spaced apart from each other are fixedly connected to the right position of the upper end of the mounting plate 30. A winding shaft 33 is connected to the two vertical plates 32 for common rotation. A fifth motor 34 for driving the winding shaft 33 to rotate is fixedly installed on the front vertical plate 32. A nylon webbing 35 is wound around the winding shaft 33. A plug plate 36 is fixedly connected to the end of the nylon webbing 35 away from the winding shaft 33. A bayonet is provided at the center of the plug plate 36. A locking mechanism is provided at the upper end of the mounting plate 30. The locking mechanism includes The lock box 37 is fixedly connected to the upper end of the mounting plate 30 and is arranged on the left side. A socket 38 matching the plug plate 36 is opened on the left side of the lock box 37. A lifting block 39 is arranged on the upper end of the lock box 37. A telescopic groove 40 is opened at the lower end of the lifting block 39. A trapezoidal block 41 is slidably connected in the telescopic groove 40. The inclined surface of the trapezoidal block 41 is arranged downward and extends into the socket 38. A spring 42 is fixedly connected between the trapezoidal block 41 and the top wall of the telescopic groove 40. A round spring 42 is fixedly connected to the front end of the lifting block 39.

The lower end of the limit rod 43 is fixedly connected to the lock box 37 to play a limiting role, so that the lifting block 39 can only move vertically. The sixth motor 49 can drive the two threaded sleeves 48 to move relative to each other through the second bidirectional threaded rod 47. When the two threaded sleeves 48 move close to each other, the two connecting rods 50 can be used to lift the round rod 45 upward, thereby driving the lifting block 39 to move upward, so that the trapezoidal block 41 moves out of the socket 38.

[0031] Specifically, when performing the freeze-drying warehouse welding work, it is only necessary to move the cylinder to the side of the contour detection mechanism, and then the mounting plate 30 can be moved to the top of the cylinder through the lifting mechanism, and the rubber block 31 can be made to fit the surface of the cylinder through the telescopic cylinder 29, and then the nylon webbing 35 can be passed through the cylinder from right to left, and then the plug 36 can be inserted into the socket 38 of the lock box 37. At this time, the trapezoidal block 41 located in the socket 38 can be directly inserted into the socket of the plug 36, so that the plug 36 cannot be separated from the lock box 37, and the locking work is completed. Then, the winding shaft 33 is driven by the fifth motor 34 to wind the nylon webbing 35, so that the nylon webbing 35 contacts and tightens the cylinder. At this time, the cylinder can be stably transferred to the contour detection mechanism through the lifting device. After the cylinder is stably placed on the contact wheel 9, it is only necessary for the fifth motor 34 to release the nylon webbing 35, so that the nylon webbing 35 remains in a loose state, and the contour detection of the cylinder can be directly performed.

[0032] After the cylinder contour detection is completed, the qualified cylinder can be directly moved to the polishing mechanism through the lifting and moving mechanism. After the cylinder is stably placed, the sixth motor 49 only needs to drive the second bidirectional threaded rod 47 to drive the two threaded sleeves 48 to move relative to each other, so as to lift the lifting block 39 and make the trapezoidal block 41 disengage from the socket 38. At this time, the plug plate 36 is unlocked, and the fifth motor 34 can directly reel in the nylon webbing 35 and pull out the plug plate 36, thereby moving it away from the position of the cylinder to carry out the bundling and lifting work of the next cylinder.

[0033] Two second electric slide rails 51 are fixedly connected to the rear end of the second support block 10 located on the rear side, and the two second electric slide rails 51 are symmetrically arranged about the welding device 12. A second transversely arranged second moving box 52 is slidably connected to the two second electric slide rails 51. Two second vertical rods 54 spaced apart from each other are slidably connected inside the second moving box 52. A third bidirectional threaded rod 53 is rotatably connected between the inner walls on both sides of the second moving box 52. The third bidirectional threaded rod 53 penetrates the two second vertical rods 54 and is threadedly connected thereto. A seventh motor 56 for driving the third bidirectional threaded rod 53 to rotate is fixedly installed on one side of the second moving box 52, and a longitudinally arranged push rod 55 is fixedly connected to the front ends of the two second vertical rods 54. Specifically, after the two cylinders are polished on the polishing mechanism, they can be transported to the positions on both sides of the welding device 12 by the horizontal conveyor line, and then the second movable box 52 can be moved forward by the two second electric slide rails 51, so that the two push rods 55 are respectively located on the far side of the two cylinders, and then the second motor 56 is used to drive the two push rods 55 to move relative to each other, so that the two cylinders can be pushed to move closer to each other so that the welding surfaces are in contact. After the two are tightly fitted, the welding device 12 can be used to directly perform the circumferential seam welding. After the welding work is completed, the push rod 55 is moved backward and reset, and the welded freeze-drying bin cylinder can be moved out of the horizontal conveyor line.
