Description

Technical Field

[0001] The present invention relates to the technical field of the structure of a tank body production line, and particularly to an on-line dust removal mechanism for a tank body production line. Background Art

[0002] When packaging cans are being produced, it is inevitable that some floating dust or ash will fall into the cans that have already been bottom-sealed. When the existing tank body production lines are designed, on-line dust removal mechanisms need to be set up; however, in actual layout, the existing mechanisms only set up fans at the bottom of the packaging cans to blow air. The hair dryers directly blow air towards the inner cavity of the cans from a long distance, resulting in the floating dust after dust removal being blown to other places, and then the packaging cans at other workstations being affected by the floating dust, so that the production line integrated with the dust removal mechanism cannot produce packaging cans with a dust-free inner cavity; for this reason, there is an urgent need to develop an on-line dust removal mechanism that can reliably remove the floating dust in the inner cavity of the can and ensure the reliable recovery of the floating dust. Summary of the Invention

[0003] In view of the above problems, the present invention provides an on-line dust removal mechanism for a tank body production line, which reliably removes the floating dust in the inner cavity of the can and reliably recovers the floating dust, ensuring that the inner cavity of the tank body obtained in production is reliably dust-removed.

The upper peripheral edge of the four sides of the upper part of the recovery cavity is fixedly installed on the outer periphery of the lower part of the relief notch. The bottom of the recovery cavity is concave. One side of the bottom of the recovery cavity is provided with an outwardly protruding recovery pipe, and the recovery pipe is externally connected to a suction device. A linear bearing mechanism is further provided at the bottom of the recovery cavity. The jacking rod passes through the linear bearing mechanism. The inner cavity of the jacking rod is empty. A nozzle is fixedly provided at the top of the jacking rod. The bottom of the jacking rod is externally connected to the output end of the second vertical lifting assembly. The bottom cavity of the jacking rod is also externally connected to a blowing device. The pressing plate is arranged directly above the nozzle.

[0005] It is further characterized in that: There are two adjacent workstations at the dust removal station. The surface area of the upper support plate covers the two adjacent workstations. Avoidance notches are provided directly below each tank body on the upper support plate. Two sets of recovery cavities are respectively fixedly connected to the lower outer circumference corresponding to the avoidance notches. Each dust removal station corresponds to a set of lifting rods and air nozzles. Two dust removal stations share a set of second vertical lifting components. The second vertical lifting components include a motor, a synchronous belt, a driving wheel, a driven wheel, a vertical track, and a connecting frame. The motor is fixedly installed on the base. The output end of the motor is fixedly provided with the driving wheel. The lower surface of the upper support plate is fixedly provided with the driven wheel. The driving wheel and the driven wheel are meshed and connected by the synchronous belt. The middle part of the synchronous belt in the height direction is fixedly connected with the connecting frame. The connecting frame is horizontally arranged. One side of the vertical connecting rod is fixedly provided with the vertical track. The connecting frame is connected to the vertical track through a slide rail pair. The two sides of the connecting frame are respectively fixedly connected to the lower outer circumference of the lifting rod. The top of the lifting rod protrudes upward after passing through the bottom plate of the recovery cavity and is sleeved with the air nozzle. In the non-working state, the air nozzle is arranged in the recovery cavity. The bottom of the lifting rod protrudes downward from the connecting frame and is externally connected with a swivel joint, and the swivel joint is used for externally connecting a blowing device. The first vertical lifting component includes a first lifting cylinder, a second lifting guide rail, a second lifting seat, and a horizontal connecting plate. The first lifting cylinder is located at the top of the vertical bracket. The second lifting guide rail is located in the inner cavity of the vertical bracket. The back side of the second lifting seat is connected to the second lifting guide rail through a guide rail pair. The lower output end of the first lifting cylinder is fixedly connected to the second lifting seat. The front end of the bottom plate of the second lifting seat is fixedly connected to the horizontal connecting plate. Corresponding pressing plates are respectively arranged on both sides of the horizontal connecting plate. Preferably, second lifting cylinders are further respectively arranged on both sides of the horizontal connecting plate. The lower output ends of the second lifting cylinders are fixedly connected with pressing plates, which enable the pressing plates on both sides to be actually fine-tuned according to the height position of the tank body, ensuring reliable pressing on the tank body, so that the tank body will not shake during dust removal. Guide pressing blocks are respectively fixedly installed on the front end face and the rear end face of the connecting frame. Guide grooves are arranged at the positions of the vertical connecting rod corresponding to the guide pressing blocks. The inwardly protruding guide bolts of the corresponding guide pressing blocks are embedded in the guide grooves, making the linear lifting of the connecting frame stable and reliable. Preferably, it further includes a height limiting seat. The height limiting seat is embedded in the upper part of the vertical track in the height direction, and the height limiting seat is also fixedly connected to the corresponding position in the height direction of the synchronous belt through fasteners. The height limiting seat is used to ensure the stable and reliable position of the air nozzle when resetting. A lower convex mounting frame is arranged directly below the position of the upper support plate corresponding to the position between the two dust removal stations. The lower convex mounting frame and the side walls of the recovery chambers on both sides are an integrally assembled component.

[0006] After adopting the structure of the present invention, the upper part of the tank body is sealed at the bottom and transported to the dust removal station through the step conveyor line. Then, the pressing plate presses the top of the tank body under the action of the first vertical lifting component. The second vertical lifting component drives the lifting rod to rise along the linear bearing, so that the air nozzle extends into the inner cavity of the tank body. The blowing device blows air from the air nozzle into the inner cavity of the tank body through the hollow lifting rod. At the same time, the air suction device sucks air synchronously, so that the separated dust is sucked along the recovery chamber into the recovery pipe. After the operation is completed, first turn off the blowing device and then turn off the air suction device. Then, the second vertical lifting component drives the suction nozzle to reset, and the first vertical lifting component drives the pressing plate to reset, and the dust removal operation is carried out repeatedly. Among them, since the lifting rod moves up and down relative to the bottom plate of the recovery chamber through the linear bearing, it ensures the reliable dust recovery of the recovery chamber, and ensures the reliable lifting operation of the lifting rod and does not generate air leakage areas. It reliably removes the floating dust in the inner cavity of the tank body and reliably recovers the floating dust, ensuring that the inner cavity of the tank body obtained in production is reliably dusted.

[0018] Its working principle is as follows: The upper part of the tank body is sealed at the bottom and is transported to the two dust removal stations through the step conveyor line. Then, the pressing plate presses the top of the tank body under the action of the first lifting cylinder, and then fine-tunes the operation through the second lifting cylinder. The motor rotates to drive the synchronous belt to rotate, and then drives the jacking rod to rise along the linear bearing, so that the air nozzle extends into the inner cavity of the tank body. The blowing device blows air from the air nozzle into the inner cavity of the tank body through the hollow jacking rod. At the same time, the air suction device sucks air synchronously, so that the separated dust is sucked into the recovery pipe along the recovery chamber. After the operation is completed, first turn off the blowing device and then turn off the air suction device. Then the motor drives the suction nozzle to reset, and the first lifting cylinder drives the pressing plate to reset, and the dust removal operation is carried out in a cycle. Among them, since the jacking rod performs lifting operations relative to the bottom plate of the recovery chamber through the linear bearing, it ensures reliable dust recovery in the recovery chamber, and ensures reliable lifting operations of the jacking rod without generating air leakage areas. It reliably removes the floating dust in the inner cavity of the tank body and reliably recovers the floating dust, ensuring that the inner cavity of the tank body obtained in production is reliably dusted.
