Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe processing, in particular to a PE pipe cutting debris recovery mechanism. Background Art
[0002] When PE plastic pipes are cut, a lot of debris will be generated. These debris have recycling value. The principle of recycling debris in the current existing technology is: use a clamp to clamp the PE pipe. When the cutting tool cuts the PE pipe, the nozzle flushes the cutting area of the PE pipe. On the one hand, it is to cool the PE pipe, and on the other hand, it is to flush away the debris generated by the cutting. The debris generated by the cutting is flushed into the groove of the workbench, and then the debris is flowed into the screen plate by water for solid-liquid separation.
[0003] The problems existing in the current prior art are as follows: when the sieve plate is filtering debris, larger debris particles will remain on the surface of the sieve plate, while those particles that are too small will get stuck in the sieve holes and cause the sieve plate to be blocked. The blockage problem cannot be completely solved by flushing with water, and manual cleaning is required at this time. Manual cleaning mainly involves scraping the debris on the surface of the sieve plate. During the scraping process, the debris on the surface of the sieve plate is easily scraped into the sieve holes, causing secondary blockage of the sieve plate. Therefore, it is necessary to design a new structure to solve this problem. Utility Model Content

DETAILED DESCRIPTION
[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0033] See also Figure 1-Figure 5 The utility model provides a technical solution: a PE pipe cutting debris recovery mechanism, comprising: an operating table 1 with an opening at the upper end and a water spray assembly for cooling the PE pipe 7. In this embodiment, the water spray assembly comprises a nozzle 5 arranged at the opening of the operating table 1, and the nozzle 5 is connected to a conduit 4 and a water pump 3; a clamping assembly 6 is arranged on the wall of the operating table 1 to clamp the PE pipe 7; the PE pipe cutting debris recovery mechanism also includes at least one sieve plate 8 arranged in the operating table 1 to filter and screen the debris generated by the cutting assembly 2 cutting the PE pipe 7; in this embodiment, two sieve plates 8 are arranged and distributed longitudinally, and the sieve holes of the sieve plates 8 decrease from top to bottom to achieve graded filtering and screening;
[0034] The above technical solution can realize the solid-liquid separation of water and debris. When in use, the PE pipe 7 is first clamped by the clamping component 6, and then the PE pipe 7 is cut by the cutting component 2. The cutting produces debris, and the water pump 3 sends the water in the water tank at the bottom end of the operating table 1 into the nozzle 5 through the conduit 4. The nozzle 5 sprays water on the PE pipe 7 to cool it down. The debris flows into the upper end of the upper sieve plate 8 along with the water. The larger debris cannot pass through the sieve plate 8 and is retained on the sieve plate 8, while the fine debris mixed with water flows through the upper sieve plate 8 into the lower sieve plate 8 to achieve secondary filtration.
[0035] like Figure 2 and Figure 4 As shown, the PE pipe cutting debris recovery mechanism also includes a scraper 11 that is kept in contact with the upper surface of the screen plate 8; a collection box 20 that is detachably mounted on the outer surface of the operating table 1, the collection box 20 corresponds to the screen plate 8, and the collection box 20 is connected through a side groove 19 provided on the operating table 1, and the side groove 19 is located on one side of the corresponding screen plate 8; in this embodiment, an insert block 21 is provided on the side of the collection box 20, and a positioning sleeve 22 that matches the insert block 21 is provided on the side of the operating table 1; a positioning sleeve 22 for driving the scraper 1 1 moves in the operating table 1, thereby driving the scraper 11 to push the debris on the surface of the screen plate 8 into the collecting box 20; in this embodiment, the driving part includes: a motor 9 arranged on one side of the operating table 1, and the output shaft of the motor 9 passes through the side wall of the operating table 1; a screw rod 10 connected to the output shaft of the motor 9 at one end, and the screw rod 10 cooperates with the screw rod groove 12 provided in the scraper 11; a guide rod 13 arranged on the inner wall of the operating table 1, and the guide rod 13 slidably cooperates with the guide groove 14 provided in the scraper 11;
[0036] The above technical solution can automatically recycle the debris on the surface of the sieve plate 8. When in use, the motor 9 is started to drive the screw 10 to rotate, and the screw 10 drives the scraper 11 to slide along the surface of the sieve plate 8, so that the debris on the surface of the sieve plate 8 is scraped into the collection box 20 through the side groove 19. When the debris inside the collection box 20 is full, the collection box 20 is carried and pulled up until the insert block 21 is disengaged from the positioning sleeve 22 on the surface of the operating table 1, and the collection box 20 can be separated from the operating table 1, which is convenient for removing the debris in the collection box 20.
[0037] like Figure 3 and Figure 4 As shown, the PE pipe cutting debris recovery mechanism also includes a cleaning roller 16 arranged on one side of the scraper 11, a bracket 15 is provided on one side of the scraper 11, and the bracket 15 is rotatably matched with the end shaft of the cleaning roller 16, and the side surface of the cleaning roller 16 is provided with a cleaning brush for cleaning the sieve holes of the sieve plate 8; a rotating part for rotating the cleaning roller 16 when the sieve plate 8 moves; in this embodiment, the rotating part includes: a gear 17 arranged on the end shaft of the cleaning roller 16; a rack 18 matched with the gear 17, and the rack 18 is arranged on the inner wall of the operating table 1;
[0038] The above technical solution can automatically clean the sieve holes of the sieve plate 8. When the scraper 11 slides, it will drive the gear 17 and the rack 18 to engage and transmit, thereby driving the cleaning brush on the surface of the cleaning roller 16 to clean and block the sieve holes on the surface of the sieve plate 8 to prevent the sieve plate 8 from being blocked.
[0039] like Figure 2 As shown, the PE pipe cutting debris recovery mechanism also includes: an inclined plate 23 arranged in the operating table 1, the inclined plate 23 is located below the lowest screen plate 8, and one side of the inclined plate 23 is connected to the bottom of the side groove 19 located at the lowest; a filter screen 24 arranged in the lowest collection box 20, the filter screen 24 is connected to an opening 25 arranged on the operating table 1, and the opening 25 is located below the inclined plate 23;
[0040] The above technical solution can collect and temporarily store the debris in a unified manner. After the secondary filtration, part of the debris and water pass through the lower screen plate 8 and enter the inclined plate 23. The inclined plate 23 guides the debris and water through the side groove 19 into the collection box 20. The water passes through the filter screen 24 and the opening 25 and re-enters the water tank at the bottom end of the operating table 1 to achieve water circulation. After the debris inside the collection box 20 is full, the collection box 20 is carried and pulled up until the insert block 21 is disengaged from the positioning sleeve 22 on the surface of the operating table 1. The collection box 20 can be separated from the operating table 1, which is convenient for removing the debris in the collection box 20.
[0041] Working principle: When in use, first use the clamping assembly 6 to clamp the PE pipe 7, and then use the cutting assembly 2 to cut the PE pipe 7. The cutting produces debris, and the water pump 3 sends the water in the water tank at the bottom end of the operating table 1 to the nozzle 5 through the conduit 4. The nozzle 5 sprays water to cool the PE pipe 7. The debris flows into the upper end of the upper sieve plate 8 along with the water. The larger debris cannot pass through the sieve plate 8 and is retained on the sieve plate 8, while the fine debris mixed with water flows through the upper sieve plate 8 and enters the lower sieve plate 8 to achieve secondary filtration. Part of the debris and water pass through the lower sieve plate 8 and enter the inclined plate 23. The inclined plate 23 guides the debris and water through the side groove 19 into the collection box 20. The water re-enters the water tank at the bottom end of the operating table 1 through the filter screen 24 and the opening 25 to achieve water circulation;
[0042] When the screen plate 8 is blocked, the motor 9 is started to drive the screw 10 to rotate, and the screw 10 drives the scraper 11 to slide along the surface of the screen plate 8, so that the debris on the surface of the screen plate 8 is scraped into the collection box 20 through the side groove 19, and while the scraper 11 slides, it drives the gear 17 and the rack 18 to mesh and transmit, thereby driving the cleaning brush on the surface of the cleaning roller 16 to clean the sieve holes on the surface of the screen plate 8 to prevent the screen plate 8 from being blocked;
[0043] When the debris inside the collection box 20 is full, the collection box 20 is carried and pulled up until the insert block 21 is disengaged from the positioning sleeve 22 on the surface of the operating table 1, and the collection box 20 can be separated from the operating table 1, thereby facilitating the removal of the debris in the collection box 20.
