Description

Technical Field

[0001] The present application relates to the technical field of dust collection equipment, and more specifically, to a double dust collection device for a grain counting machine. Background Art

[0002] The tablets are counted and filled by a tablet counting machine. During the production, the tablets are separated and arranged by oscillation through multi-stage oscillating screens and vibrating corrugated plates. In this process, a large amount of drug dust is generated due to the friction between the tablets and the vibrating corrugated plates and between the tablets. The dust will be adsorbed on the dust surface and then brought into the electronic counting area. When it falls into the filling hopper, it will fall off and fly, and adhere to the photoelectric sensing head of the tablet counting machine, directly covering the photoelectric sensing head of the electronic tablet counting machine. A large amount of dust adheres to the surface of the counting sensor counting element, which will affect the accuracy of the counting. If it is cleaned manually, it is necessary to maintain a more frequent cleaning frequency to ensure the accuracy and reliability of the electronic counting.

[0003] For this reason, in practical applications, grooves are mostly opened on the vibrating corrugated plate, and then dust suction devices are added to the lower part of the groove and the counting area and the filling hopper to collect dust. For example, Chinese patent No. CN212667787U proposes a counting machine with a dust suction device. A first dust suction port is provided below the vibrating plate above the counting machine body, and the dust left by the tablets when passing through the vibrating channel can be sucked through the first dust suction port. A second dust suction port is provided at the feeding pipe in front of the vibrating plate, and the dust generated by the tablets during the feeding process can be sucked through the second dust suction port; a dust cover is provided above the vibrating plate, and a third dust suction port and an air blowing port are provided on the dust cover. The third dust suction port and the air blowing port are combined to realize the dust suction and dust removal operations on the upper part of the counting machine, further improving the dust removal efficiency. By combining the arranged dust suction ports with the vacuum cleaner, a large amount of dust left by the tablets when passing through the vibrating channel of the counting machine can be sucked away.

[0004] However, the pressure generated by the dust suction fan has a gradient change. The dust collector installed on one side cannot absorb the dust on the other side very well. If the suction force is too small, the suction force cannot absorb the dust on the other side after passing through multiple tablets, and there is still a lot of dust absorbed on the outside of the tablets on the other side. If the suction force is too large, the tablets close to the vacuum cleaner side are easily removed from the vibrating corrugated plate under the action of suction, resulting in waste of tablets. In addition, the number of dust suction ports is fixed, which cannot meet the dust suction needs of tablets of different sizes and shapes at different transmission speeds. In view of this, we propose a double dust suction device for a tablet counting machine. Utility Model Content

DETAILED DESCRIPTION

[0022] refer to Figures 1 to 4 , a technical solution proposed.

[0023] Specifically, Figure 1 and Figure 2As shown, a multi-stage oscillating screen is arranged on the top of the frame body 1, and the multi-stage oscillating screen is transmission-connected with the vibrating corrugated plate 11. When the tablet counting machine counts and fills the tablets, the tablets are oscillated, separated and arranged through the multi-stage oscillating screen and the vibrating corrugated plate 11. The working principle refers to the tablet transmission principle of a high-efficiency tablet counting machine in Chinese Patent No. CN209870956U. Dust suction pipes 2 are arranged on both sides of the vibrating corrugated plate 11, and a plurality of dust suction members 21 are fixedly arranged on the transverse length of the dust suction pipe 2. A dust suction block 22 is fixedly arranged on one side of the plurality of dust suction members 21 close to the vibrating corrugated plate 11. A through hole is opened in the middle of the dust suction block 22, and the outer side of the through hole is in contact with the side of the vibrating corrugated plate 11. The dust suction pipes 2 on both sides simultaneously absorb dust, and the two trapezoidal suction forces complement each other to vacuum the tablets on both sides of the vibrating corrugated plate 11, thereby improving the dust suction effect.

[0024] like Figure 3 and Figure 4 As shown, a closed groove 23 is provided at the top of the dust suction block 22, and a hand-held closed plate 24 is slidably connected to the inner side of the closed groove 23. The hand-held closed plate 24 is composed of a long plate and a wide plate. The length of the long plate is greater than the length of the wide plate. The long plate is fixedly connected to the upper side of the wide plate, and the size of the long plate is greater than the size of the closed groove 23. The long plate is located above the closed groove 23, and flexible rubber layers are fixedly provided on both sides of the wide plate to increase the friction between the wide plate and the through hole. When the wide plate moves to the upper area of ​​the closed groove 23, without applying external force to the wide plate, the friction between the wide plate and the through hole is greater than the weight of the wide plate itself, and the wide plate does not move. When the wide plate is completely inside the through hole, the flexible rubber layer seals the gap between the through hole and the wide plate to avoid leakage of suction in the dust suction piece 21 in the closed state, and cannot meet the dust suction requirements of tablets of different sizes and shapes at different transmission speeds.

[0025] like Figure 3 and Figure 4 As shown, a reinforcement structure is provided on the inner side of the handheld closing plate 24, and the reinforcement structure includes a movable groove 36. A movable groove 36 is provided on one side of the bottom end of the handheld closing plate 24. The front end of the movable groove 36 is set as a circular groove, and the rear end is set as a rectangular groove. A partition plate 31 is slidably connected to the inner side of the circular groove. The partition plate 31 is composed of two circular plates of different sizes. The outer size of the smaller circular plate is the same as the inner size of the dust suction port of the dust suction block 22. The smaller circular plate can be embedded in the dust suction port of the dust suction block 22 for primary sealing. The end of the smaller circular plate away from the dust suction port is fixedly connected to a larger circular plate. The larger circular plate can fit with the outer side of the dust suction port. When there is suction at the dust suction port, the larger circular plate can further fit with the outer side of the dust suction port to achieve further sealing.

[0026] The other end of the partition 31 is fixedly connected to a fixed block 32, and the other end of the fixed block 32 is rotatably connected to a limiting plate 33. Two clamping plates are fixedly arranged at the other end of the limiting plate 33, and both clamping plates are rotatably connected to the positioning block 35 through a circular shaft. The positioning block 35 consists of a short plate and a fixed plate, the middle part of the short plate is fixedly connected to the circular shaft, and the other side of the short plate is fixedly connected to a fixed plate, a threaded groove is opened in the middle of the fixed plate, and a movable rod 34 is threadedly connected to the inner side of the threaded groove. The movable rod 34 consists of a screw rod and a rotating handle, the screw rod is threadedly connected to the threaded groove, and the top end of the screw rod is fixedly connected to the rotating handle, the rotating handle is located outside the circular groove, and the circular groove is located at the top of the hand-held closing plate 24.

[0027] The handle of the movable rod 34 is rotated, and the rotation of the handle drives the screw rod of the movable rod 34 to rotate. The rotation of the movable rod 34 drives the positioning block 35 to move up and down. The longitudinal displacement of the positioning block 35 moving up and down will drive the limit plate 33 to move. When the partition 31 is completely embedded in the inner side of the movable groove 36, the limit plate 33 is in an inclined state from top to bottom. The downward movement of the positioning block 35 will push the fixed block 32 to move horizontally. The horizontal movement of the fixed block 32 pushes the partition 31 to move out of the movable groove 36. The partition 31 moves to fit the dust suction port of the fixed block 32 to achieve double sealing of the dust suction port to avoid suction leakage. The upward movement of the positioning block 35 will drive the limit plate 3 When the upper end of the limit plate 3 moves upward, the lower end of the limit plate 33 moves accordingly. The limit plate 33 moves longitudinally as a whole and also moves transversely. When the limit plate 33 moves transversely, the limit plate 33 drives the fixed block 32 to move transversely. The transverse movement of the fixed block 32 drives the partition plate 31 to move transversely, so that the partition plate 31 no longer engages with the dust collecting block 22. When the movable rod 34 rotates to the top position, the partition plate 31 is completely engaged with the inner side of the movable groove 36. Then the staff pulls the hand-held closing plate 24 to make the hand-held closing plate 24 slide inside the closing groove 23. The hand-held closing plate 24 no longer closes the dust collecting block 22, and the through hole of the dust collecting block 22 is opened for dust collecting.

[0028] When the dust suction pipes 2 on both sides absorb the dust on the outer side of the tablets on the vibrating corrugated plate 11, according to the dust suction requirements of tablets of different sizes and shapes at different transmission speeds, when it is necessary to reduce the number of dust suction parts 21 with suction force, the hand-held closing plate 24 is pressed downward, and the hand-held closing plate 24 drives the reinforcement structure to move as a whole. After the hand-held closing plate 24 is completely inserted into the dust suction block 22 along the closing groove 23, the movable rod 34 of the reinforcement structure is then rotated. The rotation of the movable rod 34 drives the longitudinal movement of the positioning block 35. The longitudinal movement of the positioning block 35 can push the fixed block 32 and the partition 31 to move horizontally until the partition 31 It is completely in fit with the suction port of the dust suction piece 21, and the dust suction piece 21 is further sealed to avoid suction leakage. When the number of dust suction pieces 21 with suction needs to be increased, the staff operates in reverse, first rotating the movable rod 34 to move the partition 31 out of the suction port of the dust suction piece 21, and then pulling the hand-held closing plate 24 to move the hand-held closing plate 24 to above the closing groove 23. At this time, the hand-held closing plate 24 no longer blocks the suction port, and the suction circulates in the dust suction pipe 2, the dust suction piece 21 and the dust suction block 22, so as to fully adsorb the dust on both sides of the vibrating corrugated plate 11 according to different needs.

[0029] Although examples of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
