[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-5 In this embodiment of the present invention, an extrusion mechanism for a storage-type hollow extrusion blow molding machine includes a frame 1. A first chamber 101 and a second chamber 102 are fixedly installed on the upper surface of the frame 1. A rotating chamber 104 is movably disposed between the first chamber 101 and the second chamber 102. A heating component 103 is fixedly installed on the outer surface of the second chamber 102. A feed pipe 105 is fixedly embedded in the outer surface of the rotating chamber 104, and a material hopper 106 is movably inserted into one end of the feed pipe 105. The hopper 106 is used to store injection molding raw material granules. Two connecting components 2 are fixedly installed between the first hopper body 101 and the second hopper body 102. The connecting component 2 includes a collar 201 fixedly installed at one end of the first hopper body 101 and the second hopper body 102 respectively. Multiple sliding sleeves 202 are fixedly installed at equal angles on the outer surface of the collar 201. The sliding sleeves 202 are rotatably connected to the sliding rails 204 inside. The feeding component 3 is movably located inside the first hopper body 101 and the second hopper body 102.
[0030] Specifically, the feeding component 3 transports the raw material that falls from the hopper 106 into the rotating chamber 104 to the second chamber 102, and heats it through the heating component 103. Then it is extruded from one end. After the injection molding is completed, the connecting component 2 enables the rotating chamber 104 to drive the hopper 106 to rotate, so that the raw material inside the rotating chamber 104 can be recycled back into the hopper 106.
[0031] Example 1
[0032] like Figure 3 and Figure 4 As shown, in this embodiment, two slide rails 204 are fixedly installed at both ends of the outer surface of the rotating chamber 104. A fastening knob 203 is screwed onto one side of the slide sleeve 202. The fastening knob 203 passes through the slide sleeve 202 and is screwed onto the threaded groove on the surface of the slide rail 204. Multiple threaded rings 107 are fixedly installed at equal angles at the lower end of the outer surface of the hopper 106. Bolts 108 are screwed onto the inside of the threaded rings 107. The bolts 108 pass through the threaded rings 107 and the feed pipe 105. A slot is provided at the upper end of the outer surface of the hopper 106. A plate 109 is movably inserted into the slot.
[0033] In this embodiment, when recycling raw materials, the first fastening knob 203 is rotated to separate it from the threaded groove on the surface of the slide rail 204. The insert plate 109 is inserted to seal the upper end of the hopper 106. Then, through the rotational connection of the slide rail 204 and the sliding sleeve 202, the hopper 106 is flipped downwards. When the second spiral feeding rod 302 is pulled, the unheated raw materials inside the rotating hopper 104 are recycled into the hopper 106. After the raw materials are recycled, the bolt 108 is tightened to separate it from the feed pipe 105, so that the hopper 106 can be completely disassembled and replaced with a new hopper 106. This facilitates the quick replacement of new raw materials according to production requirements and avoids the degradation of molding quality caused by repeated heating of excess raw materials inside the hopper.
[0034] like Figure 2 and Figure 5 As shown, in this embodiment, the feeding assembly 3 includes: a first spiral feeding rod 301 movably disposed inside the second chamber 102, a second spiral feeding rod 302 movably disposed inside the first chamber 101 and the rotating chamber 104, and a hollow rod 303 fixedly embedded in the inner surface of the first spiral feeding rod 301; the hollow rod 303 passes through the first spiral feeding rod 301 and the second spiral feeding rod 302, and is slidably connected to the second spiral feeding rod 302; an insert block 304 is fixedly installed on the outer surface of the hollow rod 303; a square groove 305 is opened on one end surface of the second spiral feeding rod 302, and the insert block 304 is movably inserted into the square groove 305.
[0035] In practice, when the raw material needs to be replaced, pull the second spiral feeding rod 302 to slide along the hollow rod 303, while the square groove 305 separates from the insert block 304. At this time, the first spiral feeding rod 301 can continue to rotate, squeezing out the raw material inside the second chamber 102, while the second spiral feeding rod 302 does not rotate with it and can rotate independently, allowing the unmelted raw material to be discharged into the hopper 106. Conversely, when the insert block 304 is inserted into the square groove 305, the first spiral feeding rod 301 and the second spiral feeding rod 302 form a whole, and the blow molding machine operates normally.
[0036] Example 2
[0037] Based on Example 1, in order to compensate for the problem that the No. 2 spiral feeding rod 302 is prone to shaking and has poor stability.
[0038] like Figure 5 As shown, in this embodiment, a second threaded ring 306 is symmetrically fixedly installed on the other end surface of the second spiral feeding rod 302. A second fastening knob 307 is screwed into the second threaded ring 306. The second fastening knob 307 passes through the second threaded ring 306 and is movably inserted into the limiting hole 308 opened on the surface of the hollow rod 303.
[0039] In practice, the second fastening knob 307 is screwed into the limiting hole 308. At this time, one end of the second spiral feeding rod 302 abuts against the first spiral feeding rod 301, and the other end is fixed to the hollow rod 303 by the second fastening knob 307, thereby improving the stability of the second spiral feeding rod 302.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0041] Furthermore, it should be understood that 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, and 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.
