Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic pallet production and processing equipment, and in particular to a material suction machine for plastic pallet production and processing. Background Technology
[0002] During the production of plastic pallets, plastic granules need to be poured into injection molding equipment for hot melting and molding. Generally, plastic granules are fed using a suction machine during production and processing. This mainly involves using suction force to draw the plastic granules to be processed into the molding equipment. To prevent dust mixed in with the plastic granules from affecting the quality, the suction machine is equipped with a filter screen inside. When the plastic granules pass through the filter screen, the dust will also pass through the filter screen, and the fan will draw the dust into the dust collection box.
[0003] After prolonged use, the filter screen in existing material suction machines may accumulate a lot of dust, which can affect the passage of dust through the filter screen. In this case, the machine needs to be stopped and the filter screen needs to be cleaned, which is quite inconvenient. Utility Model Content

[0022] Reference Figures 1-4 A material suction machine for plastic pallet production and processing includes a housing 1, a material suction machine body 2 fixedly installed inside the housing 1, a material gun 3 fixedly installed on one side of the material suction machine body 2, one end of the material gun 3 extending out of the housing 1, a material passage pipe 4 fixedly installed on the lower surface of the material suction machine body 2, a dust collection box 5 fixedly installed inside the housing 1, rotating openings on both the upper and lower surfaces of the dust collection box 5, a cylindrical filter screen 7 rotatably installed inside the dust collection box 5, with both ends of the filter screen 7 rotatably installed in the two rotating openings respectively, and the bottom of the material passage pipe 4... The end is rotatably connected to the upper surface of the filter screen 7. The feed pipe 4 and the filter screen 7 are equipped with a conveying assembly. The conveying assembly includes a rotating rod 12 and a spiral blade 13 fixedly installed on the surface of the rotating rod 12. The rotating rod 12 is located inside the feed pipe 4 and the filter screen 7, and its top end protrudes out of the suction body 2. The upper surface of the box 1 is fixedly installed with a drive motor 14. The output shaft of the drive motor 14 passes into the box 1 and is fixedly connected to the rotating rod 12. The bottom of the dust collection box 5 is fixedly installed with a fan 8 that communicates with the inside of the dust collection box 5.
[0023] The inner wall of the dust collector 5 has a sliding opening that penetrates the housing 1. A rod 9 is slidably inserted into the sliding opening. An mounting plate 10 and a mounting block are fixedly installed at both ends of the rod 9, respectively. Multiple abutment rods 11, each with its end abutting the surface of the filter screen 7, are fixedly installed at equal intervals on the surface of the mounting plate 10. The mounting block is connected to the housing 1 via a telescopic component, which includes a telescopic spring 19 sleeved on the rod 9. Both ends of the telescopic spring 19 are fixedly connected to the mounting block and the housing 1, respectively. The side wall of the housing 1 has a pressing assembly for controlling the lateral movement of the rod 9. The pressing assembly includes a crossbar 15 and an inclined plate 16. The inclined plate 16 is fixedly installed on the upper surface of the mounting block. The surface of the 6 has a through-hole 17 for the crossbar 15 to pass through. The upper surface of the inclined plate 16 has an installation port. A rotating shaft is horizontally rotatably installed in the installation port. A baffle 18 is fixedly installed at one end of the rotating shaft. The lower surface of the inclined plate 16 has a rotation-limiting port 20 that communicates with the installation port. The upper surface of the baffle 18 abuts against the wall of the rotation-limiting port 20. A mounting plate is fixedly installed on the side wall of the box 1. An electric telescopic rod 21 is fixedly installed on the lower surface of the mounting plate. One end of the crossbar 15 is fixedly connected to the drive shaft surface of the electric telescopic rod 21. A torsion spring 22 is sleeved on the rotating shaft. The two ends of the torsion spring 22 are fixedly connected to the wall of the installation port and the surface of the baffle 18, respectively.
[0024] First, the suction machine 2 is started. The material gun 3 of the suction machine 2 will suck the plastic granules to be processed into the feed pipe 4 and the filter screen 7. At the same time, the drive motor 14 is started, which makes the rotating rod 12 rotate with the spiral blades 13, thereby conveying the plastic granules located in the filter screen 7 downward. When the plastic granules pass through the filter screen 7, the dust mixed inside them will pass through the filter holes on the surface of the filter screen 7, while the plastic granules cannot pass through the filter holes. The fan 8 is started to generate suction force, which accelerates the efficiency of dust passing through the filter screen 7. At the same time, the dust can be sucked into the dust collection box 5 for collection.
[0025] During this process, the electric telescopic rod 21 can be activated to control the horizontal rod 15 to move vertically back and forth. When the horizontal rod 15 is at its highest point, it will be above the inclined plate 16 and correspond to the position of the mounting opening. At this time, the telescopic spring 19 will be in its natural state, and the ends of the multiple abutment rods 11 will abut against the surface of the filter screen 7. When the horizontal rod 15 moves down, it will abut against the lower surface of the baffle 18 located in the mounting opening. Since the baffle 18 is restricted by the rotating opening 20 and cannot rotate downward, the horizontal rod 15 will slide along the surface of the baffle 18 to the upper surface of the inclined plate 16. Under the pressure of the inclined surface, the insertion rod 9 will move away from the filter screen 7 along with the mounting plate 10 and the multiple abutment rods 11. The ends of the multiple abutment rods 11 will no longer abut against the filter screen 7. When the surfaces come into contact, the telescopic spring 19 will stretch. Then, as the crossbar 15 moves down, when the crossbar 15 moves down to correspond to the position of the through hole 17, the crossbar 15 will pass through the through hole 17 and no longer contact the inclined plate 16. The pressure force on the inclined plate 16 will disappear, and the inclined plate 16 will quickly move and reset under the elastic potential energy of the telescopic spring 19. The ends of the multiple reset abutment rods 11 will collide with the filter screen 7. Then, the electric telescopic rod 21 will move the crossbar 15 upward. During the upward movement, the crossbar 15 will abut against the lower surface of the baffle 18 and push the baffle 18 to rotate upward until the crossbar 15 passes out of the installation hole and no longer contacts the baffle 18. Then, the baffle 18 will quickly rotate and reset under the elastic potential energy of the torsion spring 22.
[0026] The horizontal bar 15 is controlled to move vertically back and forth, which can control multiple abutment bars 11 to intermittently collide with the filter screen 7. When the abutment bars 11 collide with the filter screen 7, a physical impact force is generated. After being subjected to this impact force, the filter screen 7 will vibrate. Due to inertia, the dust attached to the surface and mesh of the filter screen 7 cannot vibrate quickly with the filter screen 7, thus separating from the filter screen 7 and falling off the screen. At the same time, the impact of the abutment bars 11 can disrupt the balance of the adsorption force of dust on the surface and mesh of the filter screen 7, breaking the relatively stable adhesion structure between the dust and the filter screen 7, making it easier for the dust to detach from the filter screen 7. The impact of the abutment bars 11 can cause local deformation of the filter screen 7. This deformation helps to squeeze out the dust stuck in the mesh, restore the mesh to its unobstructed state, and ensure the normal operation of the filter screen 7.
[0027] The sliding opening and the insertion rod 9 have the same longitudinal cross-sectional shape and are not circular, which restricts the insertion rod 9 from rotating within the sliding opening, allowing the insertion rod 9 to move only laterally.
[0028] The end of the abutment rod 11 near the filter screen 7 has a spherical groove, and a rolling ball 23 is rolled and embedded in the spherical groove. The diameter of the rolling ball 23 is larger than the mesh diameter of the filter screen 7. The rotating rod 12 is fixedly connected to the filter screen 7 through the connecting rod 6.
[0029] When the rotating rod 12 rotates with the spiral blade 13, the filter screen 7 also rotates, thereby changing the contact points between the multiple abutment rods 11 and the filter screen 7, improving the integrity of cleaning the filter screen 7. The rolling ball 23 can reduce the friction between the contact surfaces of the abutment rods 11 and the filter screen 7, and at the same time, the rolling ball 23 will not enter the mesh of the filter screen 7.
[0030] In this invention, when the suction machine body 2 is working, the insert rod 9 can be controlled to move laterally and reciprocally through the pressing component, so that multiple insert rods 11 can intermittently collide with the surface of the filter screen 7, thereby shaking off the dust attached to the surface of the filter screen 7, avoiding the accumulation of dust and affecting the passing performance of the filter screen 7, and cleaning of the filter screen 7 can be completed without stopping the machine, which is convenient and quick.
[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
