Description

Technical Field

[0001] The present application relates to the technical field of extruders, and in particular to a plastic rattan melt extruder. Background Art

[0002] Plastic rattan, made of ultra-high molecular weight polyethylene, is an environmentally friendly and cost-saving alternative to real rattan. Plastic rattan is processed by a melt extruder and can be used to bundle box cargo and is very common in daily life.

[0003] When the extruder produces plastic rattan, the molten plastic needs to be poured into the extruder hopper. After the production of the plastic rattan is completed, the staff will use a wrench or screwdriver to tighten the bolts or screws that fix the hopper. After the hopper is removed from the extruder, its inner wall is cleaned and the plastic adhered to the inner wall is scraped off. Although the traditional use of bolts to fix the hopper is relatively stable, long-term screwing, disassembly and installation will cause the threads on the bolts to wear out, thereby losing the ability to screw on. In the later operation of the extruder, the hopper will become loose, resulting in the equipment not being able to operate normally. In addition, tightening multiple bolts or screws also increases manual labor, which will cause sore hands and arms of the staff over time and waste manpower. Utility Model Content

[0020] The following is combined with Figures 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a plastic rattan melt extruder. Figures 1-4 A plastic rattan melt extruder comprises an extruder body 1 and a lower hopper 3. A feed pipe 2 is fixed on the extrusion tube wall of the extruder body 1, and the feed pipe 2 is connected to the extruder body 1; a connecting plate 5 is fixed on the feed pipe 2, and a plurality of plug holes 6 are provided on the connecting plate 5; a mounting plate 4 is fixed on the bottom of the lower hopper 3, and the mounting plate 4 is connected to the connecting plate 5; it also includes a limiting mechanism, which is installed on the connecting plate 5 and is used to limit and fix the lower hopper 3 on the connecting plate 5. A plurality of plug plates 14 are fixed at the bottom of the mounting plate 4, and the plug plates 14 are adapted to the plug holes 6. The plug plates 14 are provided with plug holes 15. Every two plug plates 14 form a group, and the two plug plates 14 in the same group are symmetrically distributed.

[0022] A plurality of fixed plates 8 are fixed to the bottom of the connecting plate 5, and each two fixed plates 8 form a group. The two fixed plates 8 in the same group are symmetrically distributed. The limiting mechanism includes a bidirectional threaded rod 9 rotatably installed on the two groups of fixed plates 8 respectively. The bidirectional threaded rod 9 is slidingly connected to the fixed plates 8 at both ends thereof. A pair of movable plates 11 are screwed on the bidirectional threaded rod 9. The two movable plates 11 are symmetrically distributed, and an insertion rod 12 is fixed on the away surfaces of the two movable plates 11. The insertion rod 12 is adapted to the insertion hole 15. One end of the bidirectional threaded rod 9 extends from the fixed plate 8 and is fixed with a manual knob 13.

[0023] When in use, pour the molten plastic into the lower hopper 3, start the extruder body 1 to extrude plastic rattan from its discharge end. This production process and principle are all existing technologies. After processing is completed, wait for the plastic attached to the lower hopper 3 to cool and form, and then turn the manual knob 13 counterclockwise in turn. At this time, the two movable plates 11 on the two-way threaded rod 9 will move closer to each other. After observing that the insertion rod 12 is away from or out of the insertion hole 15, the other two-way threaded rod 9 can be operated. After the operation of the two sets of two-way threaded rods 9 is completed, the lower hopper 3 with the limit released can be lifted up and removed, thereby simplifying the operation, saving manpower, and saving disassembly and assembly time.

[0024] In this embodiment, if Figure 2 and Figure 3As shown, a guide rod 10 is fixed on the same group of fixed plates 8 and below the two-way threaded rod 9. The guide rod 10 passes through the two movable plates 11 on this side and is slidingly connected to the two. The guide rod 10 can force the movable plate 11 to be in a vertical state as shown in the figure, avoiding the rotation of the movable plate 11 when the two-way threaded rod 9 rotates or due to the rotational relay force, thereby facilitating the normal use of the device mechanism, so that the insertion rod 12 on the movable plate 11 can always correspond horizontally to the insertion hole 15.

[0025] In this embodiment, if Figure 3 As shown, a chamfer 7 is provided at the notch of the plug hole 6 , and the chamfer 7 can increase the depression of the notch of the plug hole 6 , thereby making it more convenient to insert the plug board 14 .

[0026] The implementation principle of a plastic rattan melting extruder according to an embodiment of the present application is as follows: when in use, the molten plastic is poured into the lower hopper 3, and the extruder body 1 is started to extrude the plastic rattan from its discharge end. This production process and principle are both existing technologies. After processing is completed, wait for the partially adhered plastic in the lower hopper 3 to cool and form, and then turn the manual knob 13 counterclockwise in sequence. At this time, the two movable plates 11 on the bidirectional threaded rod 9 will move closer to each other. After observing that the insertion rod 12 is away from or out of the insertion hole 15, the other bidirectional threaded rod 9 can be operated. After the operation of the two sets of bidirectional threaded rods 9 is completed, the lower hopper 3 with the limit released can be lifted up and removed, thereby simplifying the operation, saving manpower, and saving disassembly and assembly time.
