Description

Technical Field

[0001] The present invention belongs to the technical field of can lid removing and lid closing devices, and in particular, relates to an automatic lid removing and lid closing device for a RGV can. Background Art

[0002] In the production process of electronic glass, the glass raw materials are weighed and mixed in a certain proportion, and the qualified mixture needs to be transported to the kiln head silo for use in the melting furnace. Because special electronic glass has high requirements for the uniformity of the raw material batch, the RGV unit material tank can be used for the electronic glass production raw material batch. It not only runs smoothly, but also can be used as a container for storing raw materials, with less stratification, and can be transported vertically or horizontally.

[0003] Before the RGV unit material tank receives the mixed material in the mixer, the material tank cover needs to be removed in advance. When the material tank is full of materials, in order to avoid dust overflow and meet the sealing requirements of the mixed material, the material tank cover needs to be closed, and the full material tank is sent to the furnace for standby.

[0004] The above-mentioned existing technical solutions have the following shortcomings: the RGV unit material tank automatically transports the material tank filled with mixed materials to the front of the furnace on the set route through the chain conveyor, and transports the empty material tank back to the raw material workshop. Before and after the material tank is loaded, the lid and lid closing operation must be performed manually by climbing onto the material tank. Before the RGV unit material tank needs to be loaded, the person manually climbs up to the lid removal platform through the step ladder, lifts the material tank lid and places it on the lid removal platform; when the material tank is full of materials, the person manually climbs to the lid removal platform, lifts the material tank lid and places it on the material tank. This operation not only has safety hazards, but also has low efficiency, affects the batching rhythm, and increases labor costs. Summary of the invention

[0005] The present invention provides an automatic cover taking and closing device for RGV material tanks, so as to solve the problem of manual cover taking and closing of RGV unit material tanks in the prior art, eliminate potential safety hazards to the greatest extent, reduce personnel costs, and improve batching efficiency and stability.

[0034] Specifically, Figure 1As shown, the lifting mechanism 3 includes a lifting cylinder 31 and a lifting beam 32. There are multiple lifting cylinders 31. In the present embodiment, there are two lifting cylinders 31. The two lifting cylinders 31 are respectively fixed to both sides of the mounting plate 1 by four sets of countersunk bolts. At the same time, the mounting holes on the mounting plate 1 at the connection parts with the lifting cylinder 31 are designed as long holes in the up and down directions, so that the up and down positions of the lifting cylinder 31 can be adjusted. The lower end of the lifting cylinder 31 is a double telescopic rod structure, which increases the stability of the lifting mechanism 3. The end heads of the double telescopic rods are designed as hollow internal thread structures, which are fixedly connected to the lifting beam 32 by hexagonal bolts. The lifting beam 32 is an aluminum profile slideway structure, which can realize the horizontal clamping mechanism 4 to be adjustable left and right to meet the different sizes of tank covers.

The other end of the positioning lever 522 is arranged in the bearing seat 10 and rotates freely through the bearing 11. The top of the other end of the positioning lever 522 is connected with a gear 524 through a keyway. The gears 524 in the two sets of clamping and positioning assemblies 52 are meshed with each other, and the length of the telescopic section can be adjusted through the middle connecting section 523 to increase the active radius of the positioning lever 522 and solve the problem of jamming during the movement of the positioning lever 522. The top ends of the two sets of positioning levers 522 are transmitted through the gear 524, which can solve the problem of consistency of the activities of the two sets of positioning levers 522.

[0037] Specifically, Figure 1 As shown, the tank cover detection assembly 6 includes a detection bracket 61 and a magnetic proximity switch 62. The top of the detection bracket 61 is welded to the mounting plate 1. A circular mounting hole is designed at the bottom of the detection bracket 61.

[0038] Specifically, Figure 1-4 As shown, the horizontal two-way telescopic cylinder 41 and the positioning cylinder 521 both include a horizontal extension air inlet and a horizontal retraction air inlet, and knob-type connectors 12 are provided at the horizontal extension air inlet and the horizontal retraction air inlet.

[0039] The operating principle of the present invention is as follows.

[0040] Adjust the up and down position of the lifting cylinder 31, the left and right position of the horizontal clamping mechanism 4, etc. to adapt to the different sizes of tank covers. Connect the compressed air to the air ports of the horizontal two-way telescopic cylinder 41, the positioning cylinder 521 and the lifting cylinder 31 through the knob-type connector 12 to ensure that each cylinder can be retracted and extended normally.

[0041] When the cover needs to be removed before the tank is filled with the mixed material, the RGV tank 8 is automatically transported to the cover removal and closing station by the chain conveyor, and the two horizontal two-way telescopic cylinders 41 in the horizontal clamping mechanism 4 extend, driving the two tank cover lifting plates 42 to approach the tank cover, and the tank cover lifting plates 42 extend into the gap between the RGV tank cover 7 and the upper lifting plate 9 until the tank cover lifting plates 42 contact the RGV tank cover 7; then the positioning cylinder 521 extends, driving the middle connecting section 523 and the positioning lever 522 to move, and the clamping part of the positioning lever 522 clamps the RGV tank cover The upper lifting plate 9 of the sub 7, and at the same time, since one end of the positioning lever 522 is transmitted through the gear 524, the two sets of gears 524 are meshed, ensuring that the two sets of positioning levers 522 can move synchronously; after the clamping and positioning mechanism 5 clamps the upper lifting plate 9, the lifting mechanism 3 starts to work, and the lifting cylinder 31 extends, driving the lifting beam 32 and the horizontal clamping mechanism 4 to move upward together, thereby lifting the RGV tank cover 7 from the RGV tank 8. At this time, the magnetic proximity switch 62 in the tank cover detection assembly 6 will detect the signal of the lifted tank cover, confirming that the cover is successfully removed.

[0042] When the RGV unit tank is filled with mixed materials, it is transported to the taking and closing position again through the chain conveyor. The lifting mechanism 3 begins to descend and puts the tank cover back on the tank. At this time, the horizontal clamping mechanism 4 and the clamping and positioning mechanism 5 still maintain the clamping state; after the RGV tank cover 7 is stabilized, the horizontal clamping mechanism 4 and the clamping and positioning mechanism 5 begin to loosen, the horizontal two-way telescopic cylinder 41 and the positioning cylinder 521 are shortened, and the tank cover lifting plate 42 and the positioning lever 522 are driven to leave the RGV tank cover 7 and the upper lifting plate 9 to complete the closing of the cover.

[0043] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
