In this embodiment, the PP commodity product is a new PP plate product, the material of the supporting plate 12 is an existing ordinary steel plate, the steel plate is already in the PP plate 11 when it is formed, so that the supporting plate 12 is a direct bearing stress part of the PP plate, and a more dispersed and uniform stress manner is ensured, and the circular groove 14 is dug out later, so that the PP material in the threaded hole 13 is also removed.

In addition, the whole mounting post is divided into a threaded post 15 and two connecting posts 16, because one connecting post 16 needs to pass through the threaded hole 13, in order to prevent the connecting post 16 from accidentally wearing the threads in the threaded hole 13, the diameter of the connecting post 16 is properly smaller than that of the threaded post 15, and the diameter of the circular groove 14 is larger than that of the threaded hole 13, so that the whole mounting post can be inserted into the threaded hole 13 more easily.

Thus, in this way, a relatively large annular groove is left between the connecting column 16 and the circular groove 14, which is prone to dust accumulation, and the function of the blocking ring 17 is to ensure the complete PP sheet product.

The inner ring surface of the circular groove 14 and the outer ring surface of the blocking ring 17 are both provided with thread sections.

In this embodiment, the outer annular surface of the plugging ring 17 is screwed with the inner annular surface of the circular groove 14, so that the plugging ring 17 can be ensured to be more stably installed, and at this time, an axial groove for applying force to rotate needs to be formed in the plugging ring 17 to ensure that the plugging ring 17 can be smoothly screwed in and out.

A production method of PP (polypropylene) daily necessities products comprises the steps of firstly forming the circular groove 14 on the PP plate 11 by using a drilling machine, then drilling the hole in the threaded hole 13 to remove PP materials, and finally forming the threaded section on the inner annular surface of the circular groove 14, wherein the drilling and the threaded section forming are both operated in a recovery type dust remover.

In this embodiment, the circular groove 14 is formed by punching the PP plate 11, and then the inner annular surface of the circular groove 14 is provided with threads, and the PP material in the threaded hole 13 needs to be punched and removed, but the size of the punched hole is smaller than the diameter of the threaded hole 13, after all, the cutter head is damaged, and the remaining small part of the PP material can be extruded, crushed and extruded when the threaded post 15 is screwed in, so that the whole use is not affected.

And finally, the punching and thread opening operations are carried out in the recovery type dust remover, so that the plastic particles are prevented from being scattered randomly, and the plastic particles can be collected and recycled in order.

The utility model provides a recovery type dust shaker, includes dust shaker framework 1, framework opening 2, dust removal suction opening 3 to and net cloth 4, still including setting up just be located on the top surface in the dust shaker framework 1 the 3 below positions department of dust removal suction opening and through the mode of the flourishing water of inside are in with the receipts material frame unit 5 that is used for keeping in plastic granules an, set up and be in receive articulated feed opening unit 6 on the material frame unit 5 bottom plate, and set up and be in receive on the material frame unit 5 and be used for under the brush plastic granules an, the rotation down on the net cloth 4 are opened articulated feed opening unit 6's slip brush body unit 7.

In this embodiment, all drilling equipment, screw thread are seted up equipment and are located in dust shaker framework 1 receipts material frame unit 5 below, can upwards be driven by powerful air current after plastic granules a produces, finally "inhale" on net cloth 4, if can not follow plastic granules a this moment take off on the net cloth 4, then effective convulsions flow is just more and more littleer, and final convulsions dust removal operation is just directly inefficacy, and the air exhauster all probably burns out even.

Therefore, the using method of the recovery type dust remover sequentially comprises the following 4 steps.

Firstly, the exhaust fan is opened, then the operation of punching and threading is started, the plastic particles a on the gridding cloth 4 are more and more, the air is obviously not pumped, and the exhaust fan is closed at the moment.

Secondly, the plastic particles a on the gridding cloth 4 are inconvenient to fall into the material receiving frame unit 5, a small part of the plastic particles a is remained on the gridding cloth 4, and at the moment, the sliding brush body unit 7 brushes on the lower surface of the gridding cloth 4 to gather almost all the plastic particles a in the material receiving frame unit 5.

Thirdly, the sliding brush body unit 7 is received and slides forwards again until the plastic particles a in the material receiving frame unit 5 are shifted to the hinged feed opening unit 6, and the hinged feed opening unit 6 is a recycling outlet of the plastic particles a.

Fourthly, the receiving device is prepared under the hinged feed opening unit 6, at the moment, the sliding brush body unit 7 slides forwards at last, the hinged feed opening unit 6 is stirred to rotate downwards to be opened, so that the plastic particles a all fall into the receiving device and leave the recovery type dust remover, and the complete plastic particle recovery operation is completed.

Receive material frame unit 5 and include opening rectangle framework 501 up, set up and be in on the bottom surface in the rectangle framework 501 and keep away from 2 side position departments of framework opening and keep in the water fluting 502 of plastic granules an after flourishing water, and set up rectangle framework 501 upper surface with vertical spliced pole 503 between the top surface in the dust shaker framework 1, dust removal suction opening 3 is in projection on the rectangle framework 501 compares in articulated feed opening unit 6 keeps away from more framework opening 2.

In this embodiment, there is water in the water body slot 502, and a little water needs to be supplemented in the interval time, because the plastic particles a take away part of the water when being recovered, and the purpose of the water body slot 502 is to: 3-5 times of the mesh cloth 4 is fully extruded with the plastic particles a and then all the plastic particles a are brushed off and collected, so that the plastic particles a can be intensively taken out and collected once, and the recovery operation is guaranteed to have the advantages of high efficiency and convenience.

Similarly, if the water body slot 502 is not provided, the hinged feed opening unit 6 is not necessary, i.e. the whole plastic particle recovery operation is the shutdown of the exhaust fan, and the plastic particle falling and recovering operation must be performed once, which is very inefficient and troublesome.

The hinged feed opening unit 6 comprises a rectangular opening 601 which is arranged on the bottom plate of the rectangular frame 501 and is close to the position of one side of the frame opening 2, a hinged shaft 602 which is arranged in the rectangular opening 601 and is far away from the position of one side of the frame opening 2, a rectangular sealing plate 603 which is arranged in the rectangular opening 601, and a mounting hole 604 which is arranged in the rectangular sealing plate 603 and is used for inserting and mounting the hinged shaft 602.

In the present embodiment, the rectangular sealing plate 603 functions as: 1. the operation of shifting a large amount of plastic particles a in the water body slot 502 to the upper surface of the rectangular sealing plate 603 has the advantages of multiple shifting and centralized blanking, if only the rectangular opening 601 is provided and the rectangular sealing plate 603 is not provided, the particle receiving device below the rectangular opening 601 needs to be in place for a long time, and the particles are shifted down in the particles continuously, which is time-consuming and troublesome; 2. the rotating opening position of the rectangular sealing plate 603 is fixed, so that the opening can be intensively blanked, and the specification of the receiving device is not required to be too large; 3. the upper surface of the rectangular sealing plate 603 inclines towards one side of the water body slot 502, so that the water part connected with the plastic particles a can flow back into the water body slot 502, the period of water replenishing required in the water body slot 502 is greatly prolonged, and the water replenishing is very convenient and efficient.

The hinged feed opening unit 6 further comprises a torsion spring which is arranged in the mounting hole 604 and is sleeved with the hinged shaft 602 and used for keeping the rectangular sealing plate 603 in a horizontal sealing state, and a vertical plate 605 which is arranged on the upper surface of the rectangular sealing plate 603 and used for receiving the toggle rotation driving force of the sliding brush body unit 7.

In this embodiment, the rectangular sealing plate 603 is further provided with elastic strips on four sides for sealing the rectangular opening 601, and the elastic strips have two functions: firstly, air leakage at gaps around the rectangular opening 601 and the rectangular sealing plate 603 is avoided, otherwise, certain plastic particles are accumulated at the gaps, and the plastic particles at the gaps can block the rotating opening action of the rectangular sealing plate 603; secondly, a large amount of water leakage at the gap is avoided, after all, the plastic particles a on the upper surface of the rectangular sealing plate 603 have partial moisture, and the moisture needs to flow back to the water body slot 502.

In addition, the end point of the forward sliding of the sliding brush body unit 7 is to shift the vertical plate 605, so as to ensure that the rectangular sealing plate 603 is properly inclined downwards for plastic particle discharging operation.

The sliding brush body unit 7 comprises a mounting column 701 arranged on the vertical connecting column 503 at a position close to one side of the frame body opening 2, an air cylinder 702 arranged on the mounting column 701, a brush plate 703 arranged on the cylinder shaft of the air cylinder 702, upper bristles 704 arranged on the upper surface of the brush plate 703 and used for brushing off the plastic particles a on the gridding cloth 4, a poking plate 705 arranged on the lower surface of the brush plate 703 and used for driving the vertical plate 605 to rotate when sliding and retracting, and lower bristles 706 arranged on the lower end surface of the poking plate 705 and used for poking the plastic particles a from the water body open groove 502 to the rectangular sealing plate 603.

In this embodiment, the initial state of the sliding brush unit 7 is that the brush plate 703 is located on the side of the mesh fabric 4 away from the cylinder 702, i.e. the side where the cylinder axis extends the most, and the end point of the operation of the sliding brush unit 7 is that the dial plate 705 dials the vertical plate 605, but the vertical plate 605 can never get over the vertical plate, otherwise the vertical plate 605 directly blocks the reset path of the dial plate 705.

The lower bristles 706 are initially bent and supported on the inner bottom surface of the rectangular frame 501, then extend into the water in the water body groove 502, and all plastic particles a in the water are pushed to the upper surface of the rectangular sealing plate 603, and finally, the lower bristles are simply bent and touched meaninglessly on the upper surface of the rectangular sealing plate 603.

In the horizontal direction, the water body slot 502 is closer to the frame opening 2 than the dust extraction air inlet 3.

In this embodiment, the upper bristles 704 have a flat-throwing effect of brushing off plastic particles on the mesh cloth 4, so the water body slot 502 needs to be located at the front end of the flat-throwing action, i.e., the water body slot 502 is located further forward in the moving direction of the upper bristles 704.

Before the rectangular sealing plate 603 is rotated downwards and opened, the opening 2 of the frame body already extends into the plastic particle receiving box b, and before the sliding brush body unit 7 is opened, the exhaust fan connected with the dedusting exhaust opening 3 is closed.

In this embodiment, when the exhaust fan is turned off, the upper bristles 704 brush the plastic particles on the mesh cloth 4 once, but the lower bristles 706 do not enter the water body slot 502, so that the water body slot 502 is only operated to advance in a small retraction manner, and the sliding brush unit 7 needs to be reset to the initial maximum elongation before the exhaust fan is turned on next time.

After the last brushing operation of the plastic particles on the mesh cloth 4, the lower bristles 706 enter the water body slot 502 to perform the subsequent plastic particle blanking and collecting operation, so that the recycling type dust remover in the embodiment has the advantages of multiple plastic particle interception and one-time centralized blanking recovery.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
