Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, in particular to a material head recycling device for extruding plastic sealing strips. Background Art

[0002] In the actual production and manufacturing of sealing strips, it is necessary to use an extruder for extrusion processing. The plastic extruder is mainly composed of a feeding system, an extrusion system and other parts. The extrusion system is the core part of the entire equipment. The plastic extruder uses the heated plastic to pass it through the mold through the extruder head to form the required product, thereby realizing the plastic deformation of the plastic material. The head of the sealing strip extrusion needs to be cut off. During the extrusion process of the sealing strip, the front end is often irregular in shape or has defects due to factors such as unstable pressure and uneven temperature when the extruder starts working. Cutting off this part can ensure the quality and appearance of subsequent products and ensure dimensional consistency. The current plastic sealing strip extrusion head recovery device is not convenient for mixing the head with the particles in the extruder hopper for recycling and reuse. Most of them are uniformly recycled after cutting, and this part of the head will be wasted. At the same time, the accumulation of a large number of heads also affects the economic cost. When the accumulation is too much, the impurities exceed the standard, and it is not convenient for normal reuse. At the same time, manual operation is not efficient enough. The head is very easy to stick to the knife when cutting, and it needs to be cleaned frequently. It is not convenient to use the heat of the extruder for quantitative drying after cooling and crushing. Direct reuse of the head is easy to affect the purity of the particles in the extruder hopper.

[0003] For this purpose, we propose a material head recovery device for extruding plastic sealing strips. Summary of the invention

[0025] Embodiment 2, on the basis of embodiment 1, the quantitative discharge member 7 comprises: a rotating plate 701 and a torsion spring 702, both ends of the rotating plate 701 are rotatably mounted on the heat-absorbing aluminum shell 602; the torsion spring 702 is sleeved on the side shaft end of the rotating plate 701; the rotating plate 701 is a mesh structure; the torsion spring 702 is used to drive the rotating plate 701 to maintain vertical contact with the heat-absorbing aluminum shell 602 and the breathable mesh plate 603; the quantitative discharge member 7 also comprises: a positioning control gear 703, the side shaft end of the rotating plate 701 is fixedly mounted with a positioning control gear 703; the end of the torsion spring 702 is connected to the side of the heat-absorbing aluminum shell 602, and the other end of the torsion spring 702 is connected to the inner side of the positioning control gear 703; the control rack block 605 is used to mesh and drive the positioning control gear 703 to rotate. The use of the quantitative discharge member 7 can improve the dehydration effect of the plastic particles and prevent the accumulation of the material head. This does not affect the evaporation and dehydration area, and also prevents the material head particles from being blown by the wind and discharged too quickly without being completely dried. The structure adopts a multi-level control method, which makes the discharge more uniform, ensures the drying quality, and avoids the problem that the traditional auger-type conveying structure itself is easily blocked and affects the wind discharge effect. The electric threaded rod 604 drives the control rack block 605 to move, and engages and drives the positioning control gear 703 to rotate one by one, which will drive the rotating plate 701 to rotate, so as to discharge the blocked material head particles. After the positioning control gear 703 loses the control of the rack block 605 engagement limit, the torsion spring 702 drives the rotating plate 701 to maintain a vertical blocking state, so as to prevent too many material head particles from passing through, realize limited and dispersed transportation, and the heating area is larger, and the drying is more uniform. It is sufficient to control a row of rotating plates 701 to rotate and discharge in turn.

[0026] The working principle of this embodiment is as follows: first, the recovery mounting frame 101 is used to be installed at the end of the extruder mold by bolts, and the first fragmentation driving motor 102 drives the driving column 103 to rotate, so as to control the rotation of the discharge fragmentation column 201, and the sealing strip discharged from the mold is cut into small sections by the cutter head 204. The primary crushing spring 203 used can squeeze the cutter head 204 to make it stably fit the end of the mold to cut off the material head, and the semiconductor refrigeration plate 205 is powered on for cooling to cool the material head cut off by the cutter head 204. After the material head is recovered, the magnetic attraction block 202 can be magnetically attracted by the electromagnet 104 to drive the discharge fragmentation column 201 to move to one side of the mold discharge port. During the process, the discharge fragmentation column 201 is also dialed. The movable collecting hopper 301 slides on the sliding mounting strip 1011 at the same time, driving the discharge shell 401 to align with the mold discharge port to assist in guiding the discharged sealing strip. The discharge shell 401 is connected to the water pump, and the water discharged from the extrusion plate 303 can be used to cool the extruded sealing strip. During the rotation of the discharge crushing column 201, when the cutter head 204 passes through the extrusion plate 303, it is squeezed by the inclined extrusion plate 303, and the cutter head 204 will shrink inward. The impurities of the material head attached to the surface of the cutter head 204 can be scraped and cleaned by the discharge crushing column 201. The cleaning motor 302 drives the cleaning brush 3021 to rotate, and continuously brushes the discharge crushing column 201 and the cutter head 204 for cleaning. The chopped material head will fall into the collecting hopper 301 for collection; The through hole on the heat-absorbing aluminum shell 602 is used to pass the bolts to install the heat-absorbing aluminum shell 602 at the bottom of the extruder hopper. The material head is cut off by the rotary cutter 503 and falls into the crushing cylinder 501. The rotary cutter 503 can be driven by the second crushing drive motor 502 to rotate and refine the material head again. After the material head is refined, the electric fan 504 blows the refined material head particles into the connecting bellows 601. When passing through the heat-absorbing aluminum shell 602, the material head particles are baked by the heat of the extruder hopper to achieve the effect of dehydration. Finally, the fine particles are introduced again through the reuse discharge pipe 606 The extruder hopper can be heated and extruded. During the process, the electric threaded rod 604 drives the rack block 605 to move, which can engage and drive the positioning control gear 703 to rotate one by one, and drive the rotating plate 701 to rotate, so as to discharge the blocked material particles in sequence. As the control rack block 605 moves, when the control rack block 605 is disengaged from a row of positioning control gears 703 in turn, the torsion spring 702 drives the rotating plate 701 to maintain a vertical blocking state, so as to avoid excessive material particles from passing through and realize limited and dispersed transportation.
