Description

Technical Field

[0001] This utility model relates to the field of putty powder testing technology, specifically a mechanism for ejecting substandard putty powder from a conveyor line. Background Technology

[0002] The putty powder conveying line mainly uses the airflow generated by the fan to transport materials in a closed conveying pipeline along the airflow direction. This conveying method can effectively prevent the conveyed materials from getting damp, dirty or mixed with foreign objects, thus ensuring product quality.

[0003] After production, putty powder may be incompletely crushed, resulting in some putty powder particles being too large and thus unqualified. During the conveying process, unqualified products need to be screened and separated for secondary processing. Most of the existing putty powder conveying lines have an open structure for the non-conforming product ejection mechanism. During the screening and ejection of unqualified products, impurities may be mixed into the putty powder, and the putty powder may become damp. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for ejecting substandard products from a putty powder conveying line, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-compliant product ejection mechanism for a putty powder conveying line, comprising a screening tube, a semi-circular opening in the middle section of the screening tube, a screening mesh inserted into the semi-circular opening, a support frame at the top of the screening mesh, an operating port at the top of the support frame, a pull rod inside the support frame, two uprights at the bottom of the pull rod, a cavity through the surface of the support frame below the two operating ports, the bottom of the two uprights extending to the cavity, an extension rod at each extension end of the two uprights, a movable filter screen connected to the opposite ends of the two extension rods, the bottom of the movable filter screen extending to the screening mesh, a return spring on the outer surface of the upright at the cavity, a first three-way valve outside the screening tube at the front end of the semi-circular opening, a fan installed at the other port of the first three-way valve, a second three-way valve outside the screening tube at the rear end of the semi-circular opening, and a non-compliant product discharge pipe installed at the other port of the second three-way valve.

[0006] Preferably, both ends of the screening tube are provided with connecting flanges. The putty powder conveying line mainly uses the airflow generated by the air pump to convey materials in the closed conveying pipeline along the airflow direction. When it is necessary to sort out unqualified putty powder, the screening tube can be installed between the two conveying pipelines of the conveying line through the connecting flanges.

[0007] Preferably, the outer surface of the outer screening tube of the support frame is provided with a support frame, which supports the support frame so that the support frame can be inserted into the semi-circular opening.

[0008] Preferably, two encryption gaskets are provided on the inner wall of the screening tube near the semi-circular opening, and arc-shaped baffles matching the encryption gaskets are provided at both ends of the top edge of the screening mesh. When the support is inserted into the semi-circular opening, the arc-shaped baffles are in close contact with the top of the encryption gaskets, improving the sealing at the connection point.

[0009] Preferably, the screening mesh and the movable filter have the same sieve hole diameter, and the surface of the screening mesh has holes that match those of the movable filter. When the bottom of the movable filter coincides with the holes of the screening mesh, the screening mesh and the movable filter work together to separate the putty powder inside the screening tube. Larger defective particles will be blocked by the screening mesh and the movable filter. When the movable filter is pulled up, the holes open, and the defective particles can pass through the screening mesh.

[0010] Preferably, a slot matching the movable filter is provided through the middle of the front end of the support frame, ensuring that the movable filter can move linearly up and down inside the support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The non-conforming product ejection mechanism of this putty powder conveying line uses an adjustable screening tube and a screening screen in conjunction to screen non-conforming putty powder. When screening non-conforming putty powder, the first three-way valve closes the pipe connected to the blower, and the second three-way valve closes the pipe connected to the non-conforming product discharge pipe. Putty powder enters at the front end of the screening tube, and non-conforming products are blocked by the screening screen, while conforming products are discharged through the rear end of the screening tube. When ejecting non-conforming products, the first three-way valve closes the front section of the screening tube, and the pipe connected to the blower is open. The second three-way valve closes the rear section of the screening tube, and the pipe connected to the non-conforming product discharge pipe is open. Then, the blower blows air into the middle section of the screening tube, causing non-conforming products to be ejected from the non-conforming product discharge pipe. This automatically screens and ejects coarser particles in the putty powder. Screening and ejection are carried out in a highly sealed environment, effectively preventing the putty powder from getting damp or being mixed with foreign matter.

[0013] 2. The non-compliant product ejection mechanism of this putty powder conveyor uses a plug-in support frame to facilitate the installation of the filter screen inside the screening tube, and it is also easy to disassemble for quick replacement or maintenance. Attached Figure Description

[0021] like Figures 1 to 4As shown, this embodiment discloses a non-compliant product ejection mechanism for a putty powder conveying line, comprising a screening tube 1. A semi-circular opening 9 is provided in the middle section of the screening tube 1. A screening mesh 11 is inserted into the semi-circular opening 9 inside the screening tube 1, and the screening mesh 11 matches the inner wall of the screening tube 1. When the screening tube 1 is connected to a section of the putty powder conveying line, the putty powder is filtered by the screening mesh 11, blocking coarser putty powder. A support frame 8 is provided at the top of the screening mesh 11, and an operation port 17 is provided at the top of the support frame 8. A pull rod 15 is provided inside the support frame 8, and two uprights 18 are provided at the bottom of the pull rod 15. The surface of the support frame 8 below the two operation ports 17 is perforated. A cavity 14 is provided, and the bottoms of two uprights 18 extend to the cavity 14. Each extended end of the uprights 18 is equipped with an extension rod 19, and the opposite ends of the two extension rods 19 are connected to a movable filter screen 13. The bottom of the movable filter screen 13 extends to the screen 11. If it is necessary to discharge coarser particles of putty powder blocked by the screen 11, the pull rod 15 is pulled upwards at the operating port 17. The pull rod 15 will pull the movable filter screen 13 upwards, creating a gap in the middle of the screen 11. The coarser particles of putty powder can then be discharged through this gap. The outer surface of the uprights 18 at the cavity 14 is provided with a composite... When the pull rod 15 moves upward, the return spring 16 contracts. After the defective product ejection operation is completed, the pull rod 15 is released, and the return spring 16 pulls the pull rod 15, causing the pull rod 15 to descend and push the movable filter screen 13 back to its original position, aligning it with the notch of the screening screen 11, allowing screening to continue. A first three-way valve 4 is installed on the outside of the screening tube 1 at the front end of the semi-circular opening 9, and a fan 2 is installed at the other port of the first three-way valve 4. A second three-way valve 7 is installed on the outside of the screening tube 1 at the rear end of the semi-circular opening 9, and a defective product discharge pipe 6 is installed at the other port of the second three-way valve 7. When the screening tube 1 is screening defective putty powder, When the first three-way valve 4 closes the pipe connected to the fan 2, the second three-way valve 7 closes the pipe connected to the non-conforming product discharge pipe 6. At this time, the putty powder conveyed by the conveyor line will enter the front end of the screening pipe 1. After the non-conforming products are blocked by the screening mesh 11, the qualified products are discharged through the rear end of the screening pipe 1. If it is necessary to push out the non-conforming products, the first three-way valve 4 closes the front section of the screening pipe 1, the pipe connected to the fan 2 is in the open state, the second three-way valve 7 closes the rear section of the screening pipe 1, the pipe connected to the non-conforming product discharge pipe 6 is in the open state, and then the fan 2 blows air into the middle section of the screening pipe 1, so that the non-conforming products are pushed out from the non-conforming product discharge pipe 6.

[0022] Specifically, both ends of the screening tube 1 are provided with connecting flanges 3. The putty powder conveying line mainly uses the airflow generated by the air pump to convey materials in the closed conveying pipeline along the airflow direction. When it is necessary to sort out unqualified putty powder, the screening tube 1 can be installed between the two conveying pipelines of the conveying line through the connecting flanges 3.

[0023] Furthermore, a support frame 5 is provided on the outer surface of the outer screening tube 1 of the support frame 8. The support frame 5 supports the support frame 8 so that the support frame 8 can be inserted into the semi-circular opening 9.

[0024] Furthermore, two encryption gaskets 10 are provided on the inner wall of the screening tube 1 near the semi-circular opening 9. Arc-shaped baffles 12 matching the encryption gaskets 10 are provided at both ends of the top edge of the screening mesh 11. When the support 8 is inserted into the semi-circular opening 9, the arc-shaped baffles 12 are in close contact with the top of the encryption gaskets 10, improving the sealing at the connection position.

[0025] Furthermore, the screening mesh 11 and the movable filter 13 have the same sieve hole diameter, and the surface of the screening mesh 11 is provided with holes that match the movable filter 13. When the bottom of the movable filter 13 coincides with the hole of the screening mesh 11, the screening mesh 11 and the movable filter 13 work together to separate the putty powder inside the screening tube 1. Larger unqualified products will be blocked by the screening mesh 11 and the movable filter 13. When the movable filter 13 is pulled up, the holes open, and the unqualified products can pass through the screening mesh.

[0026] Furthermore, a slot matching the movable filter 13 is provided through the middle of the front end of the support frame 8, ensuring that the movable filter 13 can move linearly up and down inside the support frame 8.

[0027] The usage method of this embodiment is as follows: The putty powder conveying line mainly utilizes the airflow generated by the air pump to transport materials along the airflow direction in a closed conveying pipeline. When it is necessary to sort out unqualified putty powder, the screening pipe 1 can be installed between the two conveying pipelines of the conveying line through the connecting flange 3. When the screening pipe 1 is screening unqualified putty powder, the first three-way valve 4 closes the pipe connected to the blower 2, and the second three-way valve 7 closes the pipe connected to the unqualified product discharge pipe 6. At this time, the putty powder conveyed by the conveying line will enter at the front end of the screening pipe 1. The unqualified products are larger particles and will be blocked by the screening mesh 11 and retained in the middle section of the screening pipe 1. The qualified products will be discharged through the rear end of the screening pipe 1. If it is necessary to push out unqualified products, the first three-way valve 4 closes the front section of the screening pipe 1, and the blower... With the pipe opening 2 open, the second three-way valve 7 closes the rear section of the screening pipe 1, and the pipe opening connected to the non-conforming product discharge pipe 6 open, pull the lever 15 upward at the operation port 17. The lever 15 will pull the movable filter screen 13 upward, creating a gap in the middle of the screening screen 11. Then, the blower 2 blows air into the middle section of the screening pipe 1, allowing coarser putty powder particles to be discharged through the gap, pushing the non-conforming products out of the non-conforming product discharge pipe 6. When the lever 15 moves upward, the return spring 16 contracts. After the non-conforming product discharge operation is completed, release the lever 15, and the return spring 16 pulls the lever 15, causing the lever 15 to descend and push the movable filter screen 13 back to its original position, aligning it with the gap in the screening screen 11, allowing screening to continue.
