A plastic extruder anti-clogging device

Abstract

This utility model provides an anti-clogging device for a plastic extruder, including an extrusion cylinder, a transmission housing, and an anti-clogging frame. A plastic extrusion groove is formed inside the extrusion cylinder. A feed cylinder is connected to the upper surface of the anti-clogging frame, and a feed channel is formed inside the feed cylinder, communicating with a discharge channel. An anti-clogging component is provided between the anti-clogging frame and the feed cylinder. This utility model has the following advantages: With the anti-clogging component, when excessive plastic raw material accumulates in the feed channel, the anti-clogging drive motor is activated, causing its anti-clogging drive shaft to rotate. The anti-clogging drive shaft synchronously drives the anti-clogging gear to rotate, which in turn drives the anti-clogging gear ring to rotate. Then, the anti-clogging connecting plate drives several anti-clogging rods to stir and discharge the plastic raw material in the feed channel. Therefore, even if too many plastic granules are added simultaneously, there will be no clogging at the feed inlet, greatly shortening the plastic extrusion and setting time.

An anti-clogging assembly is provided between the anti-clogging frame and the feed cylinder.

[0009] Furthermore, the transmission extrusion assembly includes a transmission drive motor disposed on the outer surface of the transmission housing. The output end of the transmission drive motor is connected to one end of the transmission drive shaft, and the other end of the transmission drive shaft passes through the transmission housing and is rotatably connected to one side of the transmission space.

[0010] Furthermore, the transmission extrusion assembly also includes an extrusion threaded rod with one end rotatably connected to one side of the transmission space, and the other end of the extrusion threaded rod passing through the transmission space, the transmission housing and the extrusion cylinder to the plastic extrusion groove. A transmission gear is sleeved on the outer surface of the extrusion threaded rod, and the transmission gear meshes with the drive gear.

[0011] Furthermore, the transmission extrusion assembly also includes a fixing rod with one end connected to one side end face of the plastic extrusion groove, and a fixing rod sleeve fitted on the outer surface of the other end of the fixing rod. The outer circumference of the fixing rod sleeve is connected to one end of three connecting rods respectively, and the other ends of the three connecting rods are connected to the inner side of the plastic extrusion groove.

[0012] Furthermore, the anti-clogging component includes a gear transmission groove inside the anti-clogging frame, and a limiting slot is provided on the upper and lower inner sides of the anti-clogging frame.

[0013] Furthermore, the anti-clogging component also includes two limiting plates that are rotatably connected in two limiting slots, an anti-clogging toothed ring connecting the two limiting plates, one end of an anti-clogging connecting plate fixedly connected to the inner side of the anti-clogging toothed ring, the other end of the anti-clogging connecting plate penetrating into the feed channel, and several anti-clogging rods respectively provided on one side surface of the anti-clogging connecting plate.

[0029] By adopting the above technical solution, in this embodiment, even if too many plastic granules are added at once, there will be no blockage at the feed inlet due to the anti-clogging component, which greatly shortens the plastic extrusion and setting time.

[0030] Example 2

The extrusion threaded rod 13 on the side has its other end passing through the transmission space 8, the transmission box 3 and the extrusion cylinder 1 to the plastic extrusion groove 16. The outer surface of the extrusion threaded rod 13 is fitted with a transmission gear 12, which meshes with the drive gear 11. The transmission extrusion assembly also includes a fixing rod 17 with one end connected to the end face of one side of the plastic extrusion groove 16. The outer surface of the other end of the fixing rod 17 is fitted with a fixing rod sleeve 18. The outer circumference of the fixing rod sleeve 18 is connected to one end of three connecting rods, and the other ends of the three connecting rods are connected to the inner side of the plastic extrusion groove 16.

[0032] Using the above technical solution, in this embodiment, the plastic extrusion groove 16 is connected to the feeding groove 22 by setting a connecting groove 15, so that the plastic raw material falls freely into the plastic extrusion groove 16, and then the plastic raw material is extruded by the spiral guide of the extrusion threaded rod 13.

[0033] Example 3

[0034] See Figure 3 , Figure 4 and Figure 5In addition to the above-mentioned embodiments one and two, the anti-clogging device for a plastic extruder of this utility model also has the following technical features: the anti-clogging component includes a gear transmission groove 24 opened inside the anti-clogging frame 4, and a limiting groove 23 is opened on the upper and lower inner sides of the anti-clogging frame 4 respectively. The anti-clogging component also includes two limiting plates 25 respectively rotatably connected in the two limiting grooves 23. An anti-clogging toothed ring 19 is connected between the two limiting plates 25. One end of an anti-clogging connecting plate 20 is fixedly connected to the inner side of the anti-clogging toothed ring 19. The other end of the anti-clogging connecting plate 20 passes through the feed channel 7. A plurality of anti-clogging rods 21 are respectively provided on one side surface of the anti-clogging connecting plate 20. The component includes an anti-clogging drive motor 5 mounted on the upper surface of the anti-clogging frame 4. The output end of the anti-clogging drive motor 5 is connected to one end of the anti-clogging drive shaft 26. The other end of the anti-clogging drive shaft 26 passes through the anti-clogging frame 4 and is rotatably connected to the bottom side of the gear transmission groove 24. An anti-clogging gear 27 is sleeved on the outer surface of the anti-clogging drive shaft 26. The anti-clogging gear 27 is rotatably connected in the gear transmission groove 24 and meshes with the anti-clogging gear ring 19. The anti-clogging connecting plate 20 is located between the feed channel 7 and the discharge channel 22 and has a curvature. The end of the anti-clogging connecting plate 20 located in the feed channel 7 cooperates with the feed channel 7. Three support plates 2 are respectively connected to the lower part of the outer circumference of the extrusion cylinder 1.

[0035] In this embodiment, by adopting the above technical solution, an anti-clogging toothed ring 19, a limiting plate 25, a limiting groove 23, and an anti-clogging connecting plate 20 are set. The two limiting plates 25 are rotatably connected in the two limiting grooves 23. The two limiting plates 25 provide auxiliary limiting for the anti-clogging toothed ring 19, so that the anti-clogging toothed ring 19 will not shift its position when it rotates. When the anti-clogging toothed ring 19 rotates, it synchronously drives the anti-clogging connecting plate 20 to rotate. Then, the anti-clogging connecting plate 20 drives a number of anti-clogging rods 21 to rotate in its feed channel 7. The setting of the number of anti-clogging rods 21 fully stirs the plastic raw material in its feed channel 7, preventing the plastic raw material from being blocked in its feed channel 7.

[0036] As an optimized solution for the anti-clogging device of a plastic extruder according to this utility model, when excessive plastic raw material accumulates in the feed chute 7, the anti-clogging drive motor 5 is activated to rotate its anti-clogging drive shaft 26. The anti-clogging drive shaft 26 synchronously drives the anti-clogging gear 27 to rotate, which in turn drives the anti-clogging gear ring 19 to rotate. Then, the anti-clogging connecting plate 20 drives several anti-clogging rods 21 to stir and discharge the plastic raw material in the feed chute 7. Thus, even if too much plastic granules are added at once, there will be no blockage at the feed inlet, greatly shortening the plastic extrusion and setting time.

[0037] In use, the plastic raw material is poured into the plastic extrusion tank 16 through the feed channel 7. The drive motor 9 is started to make its drive shaft 10 rotate. The drive shaft 10 drives the drive gear 11 to rotate synchronously. Then the drive gear 11 meshes and drives the drive gear 12 to rotate. Then the drive gear 12 drives the extrusion thread rod 13 to rotate synchronously. Then the extrusion thread rod 13 uses the threaded blades on its outer surface to convey the plastic raw material in the plastic extrusion tank 16. Then the plastic raw material is extruded through the outlet of the plastic extrusion tank 16.

[0038] When excessive plastic raw material accumulates in the feed trough 7, the anti-clogging drive motor 5 is activated to rotate its anti-clogging drive shaft 26. The anti-clogging drive shaft 26 synchronously drives the anti-clogging gear 27 to rotate. The anti-clogging gear 27 meshes and drives the anti-clogging gear ring 19 to rotate. When the anti-clogging gear ring 19 rotates, the sliding connection between the upper and lower limit plates 25 and their limit grooves 23 assists in the movement of the anti-clogging gear ring 19. Then, the anti-clogging gear ring 19 drives the anti-clogging connecting plate 20 to rotate in a circular motion. Then, the anti-clogging connecting plate 20 drives several anti-clogging rods 21 to stir and discharge the plastic raw material in the feed trough 7. Thus, even if too much plastic granules are added at once, there will be no blockage at the feed inlet, which greatly shortens the plastic extrusion and shaping time.

[0039] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
