Description

Technical Field

[0001] This utility model relates to a negative pressure material extraction mechanism, and more specifically to a pulse self-cleaning device for a powder suction pipe. Background Technology

[0002] Vacuum feeders typically employ vacuum feeding, which works by creating a negative pressure within the hopper cavity to draw material in. The fully automatic microcomputer vacuum feeder operates as follows: When the hopper is low on material, a material detection switch sends a signal to the feeder's microcomputer. The microcomputer then activates the motor to create a vacuum. Once the sealed system reaches a certain vacuum level, feeding begins. After feeding, material is released back into the hopper. After a preparatory period, the cycle repeats. When the hopper is full, the material detection switch sends a signal, terminating the feeding action. This continuous cycle ensures a constant supply of material to meet the equipment's needs.

[0003] Powder suction pipes are prone to blockage during transport due to dust accumulation, clumping, or particle adhesion, affecting suction efficiency and equipment lifespan. To solve this problem, a pulse self-cleaning device automatically cleans the inside of the suction pipe by periodically releasing airflow. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a pulse self-cleaning feeding device for powder suction pipes.

[0005] According to a first aspect of the present invention, a pulse self-cleaning feeding device for a powder suction pipe is provided, comprising a pulse housing, wherein the pulse housing is provided with a flow chamber and an adjustment chamber inside the pulse housing;

[0006] A pad is fixed inside the pulse housing, and a linkage adjustment structure is provided inside the adjustment cavity. The linkage adjustment structure includes a shaft that passes through the pad inside the adjustment cavity. The shaft has two three-claw wings on the upper part of the pad, and a roller is movably installed between the two three-claw wings. A sealing cavity is opened inside the pad, and multiple airflow plates are provided at the bottom of the shaft inside the sealing cavity.

[0007] Two reset springs are fixedly installed on the other side of the adjustment cavity. Z-shaped plates are fixedly connected to the ends of the two reset springs. One side of the Z-shaped plate is in contact with the three-claw wing and the roller. A sealing plate is fixedly connected to the bottom of the Z-shaped plate. A feed port is opened on the upper part of the sealing plate.

[0008] Optionally, a feed pipe and a suction pipe are respectively connected to both sides of the flow cavity, with the feed pipe located on the upper part of one side of the flow cavity and the suction pipe located on the lower part of the other side of the flow cavity.

[0009] Optionally, the sealing plate is movably connected to one side of the pulse housing, and the sealing plate is movably located inside the bottom of the pad, with the feed port corresponding to the opening of the feed pipe.

[0010] Optionally, a sealing mechanism is installed on one side of the flow chamber, the flow chamber is connected to a pulse airflow pipe on the upper part of one side of the suction tube, and a rotating ring is provided on the inner side of the pulse housing.

[0011] Optionally, a first positioning pin is fixedly provided on the inner side of the pulse housing and the inner side of the pulse airflow pipe, and a plurality of sliding grooves are provided on the rotating ring, with the first positioning pin corresponding to the sliding groove and fixedly connected to the inner side of the pulse housing.

[0012] Optionally, the inner side of the rotating ring is movably connected to a blade via a crank rod, and one corner of the blade is movably positioned inside the pulse housing via a second positioning pin.

[0013] Optionally, a connecting block is fixedly provided on one side of the rotating ring, and a connecting rod is movably connected to the connecting block via a movable chain. One end of the connecting rod is fixedly connected to a ball joint, and the ball joint is movably connected to one side of the sealing plate.

[0014] Optionally, the shaft is movably connected to the middle of the sealing cavity, the airflow plate is sealed to the inner wall of the sealing cavity, the upper end of the sealing cavity is connected to a diversion pipe, and the other end of the diversion pipe is connected to the feed pipe.

[0015] Optionally, the lower part of the sealed cavity is connected to a pressure relief pipe, and the pulse airflow pipe is connected to the output end of an external air pump via a flexible hose.

[0016] Optionally, a partition plate is fixedly provided between the flow cavity and the adjustment cavity, and the sealing plate passes through the partition plate and is movably located inside the flow cavity.

[0017] According to one embodiment of this disclosure, the self-cleaning suction device cleans using pulsed airflow. To achieve automated pulsed self-cleaning, a diversion pipe and a feed pipe are connected. When the suction pipe becomes blocked, the suction air pressure in the diversion pipe increases, which increases the negative pressure inside the sealing cavity, thereby attracting the airflow plate. The Z-shaped plate is supported by a return spring to provide support strength. When the negative pressure attracts the airflow plate, it can drive the upper three-claw fins and the push roller to rotate, and the push roller contacts the Z-shaped plate. When the negative pressure intensity is greater than the pushing strength of the return spring, the Z-shaped plate can drive the sealing plate to move, so that the sealing plate can block the feed pipe.

[0018] When the sealing plate is raised or lowered, the rotating ring is connected and rotated via a connecting rod. The rotating ring is positioned and rotated via a first positioning pin. Several blades are connected to the inner side of the rotating ring via a crank rod. The blades are positioned and rotated via a second positioning pin. This allows the rotating ring to drive the blades to rotate. When the sealing plate is raised, it can both block the feed pipe and open the blades, allowing the pulse airflow pipe to deliver pulse airflow to the flow chamber for pulse self-cleaning of the suction pipe. When the sealing plate is lowered, the blades close in conjunction with the plate, blocking the pulse airflow pipe.

[0032] A pad 5 is fixedly provided inside the pulse housing 1, and a linkage adjustment structure 4 is provided inside the adjustment cavity 3.

[0036] In this embodiment, preferably, the sealing plate 410 is movably connected to one side of the pulse housing 1, and the sealing plate 410 is movably located inside the bottom of the pad block 5, and the feed inlet 411 is correspondingly set with the inlet of the feed pipe 7.

[0037] It should be noted that the sealing plate 410 is movably connected to the pulse housing 1 and the pad 5, which facilitates the sealing performance of the sealing plate 410 and the on / off control of the airflow and material flow of the feed pipe 7.

[0038] In this embodiment, preferably, a sealing mechanism 6 is installed on one side of the inside of the flow chamber 2, and a pulse airflow pipe 611 is connected to the upper part of one side of the suction pipe 8 in the flow chamber 2. A rotating ring 601 is provided on the inner side of the pulse shell 1.

[0039] It should be noted that the sealing mechanism 6 is set to control the on / off flow of the airflow delivered by the pulse airflow pipe 611, so that the pulse airflow pipe 611 can automatically backwash the suction pipe 8 to clear any blockages in the suction pipe 8.

[0040] In this embodiment, preferably, a first positioning pin 603 is fixedly provided on the inner side of the pulse housing 1 and the inner side of the pulse airflow pipe 611, and a plurality of sliding grooves 602 are provided on the rotating ring 601, with the first positioning pin 603 corresponding to the sliding groove 602 and fixedly connected to the inner side of the pulse housing 1.

[0043] It should be noted that when the rotating ring 601 rotates, the crank 604 enables the split blades 605 to be linked and expanded, which facilitates the on / off control of the pulse airflow pipe 611.

[0044] In this embodiment, preferably, a connecting block 607 is fixedly provided on one side of the rotating ring 601, and a connecting rod 609 is movably connected to the connecting block 607 via a movable chain 608. One end of the connecting rod 609 is fixedly connected to a ball joint 610, and the ball joint 610 is movably connected to one side of the sealing plate 410.

[0045] It should be noted that, in order to achieve linkage control of the rotating ring 601, the connecting block 607 is connected through the connecting rod 609 and the movable chain 608. In this way, when the sealing plate 410 is raised and lowered, the connecting rod 609 can rotate the rotating ring 601, so that the blades 605 can retract and expand. Furthermore, the ball joint 610 is designed to facilitate adjustment and eliminate the torsional stress of the rotating ring 601 when it rotates.

[0046] In this embodiment, preferably, the shaft 401 is movably connected to the middle of the sealing cavity 404, the airflow plate 405 is sealed to the inner wall of the sealing cavity 404, the upper end of the sealing cavity 404 is connected to the diversion pipe 406, and the other end of the diversion pipe 406 is connected to the feed pipe 7.

[0047] It should be noted that the shaft 401 is located inside the sealing cavity 404, and the airflow plate 405 is sealed to the inner wall of the sealing cavity 404. This allows the diversion pipe 406 to increase the negative pressure when drawing airflow, which facilitates the suction of the airflow plate 405 and makes it easier for the airflow plate 405 to rotate.

[0048] In this embodiment, preferably, the lower part of the sealing cavity 404 is connected to the pressure relief pipe 407, and the pulse airflow pipe 611 is connected to the output end of the external air pump through a flexible hose.

[0049] It should be noted that the pressure relief pipe 407 is designed to input into the sealed cavity 404 to eliminate the influence of negative pressure, and the pulse airflow pipe 611 is used to connect to an external air pump to facilitate the delivery of high-pressure airflow to flush the suction pipe 8.

[0050] In this embodiment, preferably, a partition plate 9 is fixedly provided between the flow cavity 2 and the regulating cavity 3, and the sealing plate 410 passes through the partition plate 9 and is movably located inside the flow cavity 2;

[0051] It should be noted that the partition plate 9 is designed to separate the flow chamber 2 and the regulating chamber 3, which facilitates stable material conveying. The sealing plate 410 penetrates the partition plate 9, which facilitates the sealing of the feed pipe 7.

[0052] The specific operational procedures for this application are as follows:

[0053] When in use, first connect the output end of the external air pump to the pulse airflow pipe 611, then run the material extraction device, and connect the diversion pipe 406 and the feed pipe 7. In this way, when the suction pipe 8 is blocked, the suction air pressure in the diversion pipe 406 will increase, which will increase the negative pressure inside the sealing cavity 404, thereby attracting the airflow plate 405. The Z-shaped plate 408 is supported by the return spring 409, which provides support strength. When the negative pressure attracts the airflow plate 405, it can drive the upper three-claw wing 402 and the roller 403 to rotate, and the roller 403 contacts the Z-shaped plate 408. When the negative pressure is greater than the pushing strength of the return spring 409, the Z-shaped plate 408 can drive the sealing plate 410 to move, so that the sealing plate 410 can block the feed pipe 7.

[0054] When the sealing plate 410 is raised or lowered, the rotating ring 601 is connected and rotated via the connecting rod 609. The rotating ring 601 is positioned and rotated via the first positioning pin 603. Several blades 605 are connected to the inner side of the rotating ring 601 via the crank rod 604. The blades 605 are positioned and rotated via the second positioning pin 606. This allows the rotating ring 601 to rotate, thereby driving the blades 605 to rotate. When the sealing plate 410 is raised, it can both block the feed pipe 7 and open the blades 605, allowing the pulse airflow pipe 611 to deliver the pulse airflow into the flow chamber 2, achieving pulse self-cleaning of the suction pipe 8. When the sealing plate 410 is lowered, the blades 605 are closed, thereby blocking the pulse airflow pipe 611.
