Description

Technical Field

[0001] The present 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 principle of sublimation is used to allow the moisture in the pre-frozen material to be directly sublimated 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 mostly in the shape of a tank, and is made of multiple sections of 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, the welding head in the circular track is started to align with the weld and move in a circle, and the welding work of a section of the freeze-drying silo cylinder can be completed. This welding 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.

DETAILED DESCRIPTION

[0025] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0026] Reference Figure 1-Figure 7An automatic conveying and welding device for freeze-drying bin equipment includes a contour detection mechanism. The contour detection mechanism includes two first support blocks 1 spaced apart from each other. Each of the two first support blocks 1 is provided with a support wheel 2 on opposite sides. The support wheels 2 are multiple and equally spaced and can rotate freely forward and backward to facilitate the placement of the freeze-drying bin cylinder. The cylinder supported by the support wheels 2 can rotate stably. The two front and rear first support blocks 1 are each fixedly connected to a first mounting frame 3 on the side away from each other. The two first mounting frames 3 are each fixedly mounted with a first electric telescopic rod 4 arranged opposite to each other. The telescopic end of the first electric telescopic rod 4 located in the front is fixedly connected to a connecting plate. The end of the connecting plate away from the first electric telescopic rod 4 is fixedly connected to two elastic telescopic rods. The telescopic ends of the two elastic telescopic rods are jointly fixedly connected to a U-shaped frame. A drive wheel 5 is connected to the inner wall of the U-shaped frame and rotates together. A first motor 6 that drives the drive wheel 5 is fixedly mounted on one side of the U-shaped frame. When the first electric telescopic rod 4 drives the drive wheel 5 to contact the freeze-drying bin cylinder placed on the support wheels 2, the first motor 6 can drive the cylinder to rotate through the drive wheel 5 as long as the elastic telescopic rod remains in a compressed state. The telescopic end of the first electric telescopic rod 4 located at the rear is fixedly connected to a horizontal plate 7, and the front end of the horizontal plate 7 is fixedly connected to two pressure sensors 8 set at intervals on the left and right. The detection end of the pressure sensor 8 is connected to a contact wheel 9. The first electric telescopic rod 4 can drive the horizontal plate 7 to move so that the two contact wheels 9 are in contact with the outer peripheral surface of the cylinder near the two ends at the same time. Then, when the cylinder rotates at a uniform speed, it can be concluded whether the cylinder profile meets the standard through the change in the detection value of the pressure sensor 8.

[0027] A transverse conveyor line is provided on the left side of the contour detection mechanism. This line includes two second support blocks 10 spaced apart from each other. Multiple equally spaced electric conveyor wheels 11 are mounted on the upper ends of each of these second support blocks 10 to facilitate placement of the freeze-drying bin cylinder. The cylinder can be moved laterally along the transverse conveyor line via the electric conveyor wheels 11. A gap is provided on the left side of the transverse conveyor line, where a welding device 12 is fixedly mounted. This welding device 12 is conventional technology and can perform circumferential seam welding, so its description is omitted here.

[0028] A grinding mechanism is provided on the horizontal conveyor line and on the right side. The grinding mechanism includes two second mounting frames 13 fixedly connected to the ends away from the two second support blocks 10. The two second mounting frames 13 are fixedly mounted with second electric telescopic rods 14 arranged opposite to each other. The telescopic ends of the two second electric telescopic rods 14 are fixedly connected with positioning blocks 15. The opposite sides of the two positioning blocks 15 are arc-shaped and made of rubber material. The two second electric telescopic rods 14 can drive the two positioning blocks 15 to move relative to each other, thereby fixing and clamping the cylinder located on the horizontal conveyor line so that it cannot move. The rear end of the second support block 10 located at the rear side is fixedly connected to two longitudinally arranged first electric slide rails 16, and the two first electric slide rails 16 are symmetrically arranged about the second mounting frame 13. The two first electric slide rails 16 are jointly slidably connected to a transversely arranged first moving box 17, and a first bidirectional threaded rod 18 is jointly rotated between the inner walls on both sides of the first moving box 17. Two first vertical rods 20 are symmetrically slidably connected in the first moving box 17, and the first bidirectional threaded rod 18 passes through the two first vertical rods 20 and is threadedly connected thereto. A second motor 1 that drives the first bidirectional threaded rod 18 to rotate is fixedly installed at one end of the first moving box 17 9. The front ends of the two first vertical rods 20 are fixedly connected to the horizontally longitudinally arranged support rods 21, and the front ends of the two support rods 21 are installed with third motors 22. The two third motors 22 are arranged opposite to each other and the output ends are fixedly connected to two grinding rods 23. Specifically, the two first electric slides 16 can drive the first movable box 17 to move forward, thereby moving the two pairs of grinding rods 23 to the positions on both sides of the cylinder respectively, and then using the second motor 19 to drive the two grinding rods 23 to move relative to each other until they contact the two welding end surfaces of the cylinder, and then the third motor 22 can be used to drive the grinding rods 23 to grind the welding end surfaces to ensure the flatness of the welding end surfaces.

[0029] A lifting and moving mechanism is provided above the contour detection mechanism and the grinding mechanism. The lifting and moving mechanism includes a hanging frame 24 fixed to the ceiling. A threaded screw 25 is connected to the inner walls on both sides of the hanging frame 24 for rotation. Two sliding rods 26 are fixed to the inner walls on both sides of the hanging frame 24. The two sliding rods 26 are equidistantly distributed on the front and back sides of the threaded screw 25. A moving block 27 is slidably sleeved on the two sliding rods 26. The threaded screw 25 passes through the moving block 27 horizontally and is threadedly connected thereto. A fourth motor 28 for driving the threaded screw 25 to rotate is fixedly installed on the right end of the hanging frame 24. The fourth motor 28 can drive the moving block 27 to move horizontally.

[0030] A telescopic cylinder 29 is fixedly mounted on the lower end of the moving block 27. The telescopic end of the telescopic cylinder 29 is fixedly connected to a mounting plate 30. 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 end of the upper end of the mounting plate 30. A winding shaft 33 is connected between the two vertical plates 32 for common rotation. A fifth motor 34 for driving the winding shaft 33 is fixedly mounted on the front vertical plate 32. A nylon webbing 35 is wound around the winding shaft 33. The end of the nylon webbing 35 away from the winding shaft 33 is fixedly connected to a plug plate 36. A bayonet is provided at the center of the plug plate 36. A locking mechanism is provided on the upper end of the mounting plate 30. The locking mechanism includes The bracket is fixedly connected to the upper end of the mounting plate 30 and a lock box 37 is set 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 provided on the upper end of the lock box 37. A telescopic slot 40 is opened at the lower end of the lifting block 39. A trapezoidal card block 41 is slidably connected in the telescopic slot 40. The inclined surface of the trapezoidal card block 41 is set downward and extends into the socket 38. A spring 42 is fixedly connected between the trapezoidal card block 41 and the top wall of the telescopic slot 40. The front end of the lifting block 39 is fixedly connected to a round The second bidirectional threaded rod 47 is threadedly sleeved with two threaded sleeves 48 spaced apart on the left and right sides. The upper ends of the two threaded sleeves 48 and the round rod 45 are both rotatably connected with a connecting rod 50. A sixth motor 49 is fixedly installed on one of the end plates 46 to drive the second bidirectional threaded rod 47 to rotate. The rear end of the lifting block 39 is fixedly connected to the sleeve 44, and the sleeve 44 slides vertically through the limit rod 43. 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 push 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 welding the freeze-drying chamber, the barrel can be moved to the side of the contour detection mechanism. The mounting plate 30 can then be moved above the barrel via the lifting mechanism. The rubber block 31 can then be brought into contact with the barrel surface via the telescopic cylinder 29. The nylon webbing 35 can then be passed through the barrel from right to left. The insert plate 36 can then be inserted into the socket 38 of the lock box 37. The trapezoidal block 41 in the socket 38 can then be directly engaged with the latch of the insert plate 36, preventing the insert plate 36 from being disengaged from the lock box 37, thus completing the locking operation. Next, the fifth motor 34 drives the winding shaft 33 to wind the nylon webbing 35, causing it to contact and tighten the barrel. The barrel can then be stably moved to the contour detection mechanism via the lifting mechanism. Once the barrel is stably placed on the contact wheel 9, the fifth motor 34 simply releases the nylon webbing 35, keeping it loose, and the barrel contour detection can then 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 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 disengage the trapezoidal block 41 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. The two second electric slide rails 51 are symmetrically arranged about the welding device 12. A second horizontally arranged second movable box 52 is slidably connected to the two second movable box 52. Two second vertical rods 54 spaced apart on the left and right are slidably connected inside the second movable box 52. A third bidirectional threaded rod 53 is rotatably connected between the inner walls on both sides of the second movable box 52. The third bidirectional threaded rod 53 passes through 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 movable box 52. The front ends of the two second vertical rods 54 are fixedly connected to a longitudinally arranged push rod 55. 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 seventh 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 closer to each other and the welding surfaces can be in contact. After the two are tightly fitted, the circumferential seam welding work can be directly performed using the welding device 12. 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.
