Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic recycling extruder. Background Art

[0002] Waste plastic is a popular term that does not refer to waste, old and useless plastic products. For most plastic products, especially those that are used once in large quantities, the properties of the plastic material itself do not change significantly after use. Therefore, they can be recycled and reprocessed into plastic products using appropriate methods and then used again. After the waste plastic is recycled, it needs to be regenerated and extruded, which requires the use of an extruder.

[0003] After searching, Chinese patent announcement number: CN218366372U discloses a fully automatic extruder for plastic ABS recycled materials, which includes a base, a first motor, a heating chamber, a heating component, a cross rotating frame and a crushing component. It can crush the plastic raw materials and increase the melting speed of the plastic raw materials. The crushed plastic raw materials will enter the heating chamber and be melted by the heating component in the heating chamber. The melted plastic raw materials will be transported to the extruder body for extrusion, avoiding the problems of uneven plastic melting and long plastic melting time, thereby improving the overall use effect.

[0004] In actual use, the above-mentioned extruder uses an electric heating plate to rotate during the melting process of plastic raw materials to melt the raw materials, thereby fully contacting the raw materials to improve the heating effect. However, in the process of stirring and heating the raw materials, a large amount of molten raw materials will adhere to the inner wall of the heating chamber and cannot continue to slide down into the extruder for further processing, which greatly reduces the recycling and processing utilization rate of waste plastics. Therefore, a plastic recycling extruder is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a plastic recycling extruder, which aims to improve the problem in the prior art that the molten raw materials are easily adhered to the inner wall of the heating bin and cannot enter the extruder body during the pre-melting process of the raw materials.

[0011] As a further description of the above technical solution:

[0012] The pushing unit includes a fixing frame, which is fixedly connected to the right side surface of the heating box.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 The utility model provides an embodiment: a plastic recycling extruder, including a body 1, a motor 2 is provided on the right side of the body 1, a discharge pipe 3 is fixedly connected to the left end of the body 1, a crusher 4 is fixedly connected to the right side of the upper surface of the body 1, and a feed hopper is fixedly connected to the top of the crusher 4. The waste plastic raw materials can be put into the crusher 4 through the feed hopper for crushing. The crusher 4 is a prior art means in this field and will not be described in detail here. A heating box 5 is fixedly connected at the center of the upper surface of the body 1. The raw materials that are crushed and reduced in size inside the crusher 4 can enter the interior of the heating box 5 through the discharge hole on the left side of the crusher 4 for melting.

[0031] Reference Figure 1-Figure 2 The bottom surface of the heating box 5 is fixedly connected to a heating inclined plate 6. When the raw materials enter the heating box 5, they will fall above the heating inclined plate 6 and slide to the left along the inclined surface of the heating inclined plate 6. The heating inclined plate 6 can generate heat after being energized to heat the raw materials falling above it, so that the raw materials quickly enter the molten state and slide to the left. The top surface of the heating box 5 is fixedly connected to a vertical plate 7. The vertical plate 7 can block the raw materials entering the heating box 5 from the right, so that the raw materials can only fall to the heating inclined plate 6. The right side of the vertical plate 7 is subjected to the entire heating and melting process. The bottom end of the vertical plate 7 is hinged to the limit plate 8, and the limit plate 8 can rotate around the hinge between the vertical plate 7. The distance between the limit plate 8 and the upper surface of the heating inclined plate 6 gradually decreases from right to left. When the raw material falls above the heating inclined plate 6 and slides to the left along the inclined surface of the heating inclined plate 6, it will be blocked by the limit plate 8. As the raw material is gradually heated and melted and becomes smaller, it can gradually slide to the left in the gap between the limit plate 8 and the heating inclined plate 6, thereby avoiding the discharge of the raw material before it is melted.

[0032] A limiting unit is set above the limiting plate 8, and the limiting unit includes a fixed plate 81, which is fixedly connected to the inside of the heating box 5. The bottom end of the fixed plate 81 is fixedly connected to a spring 82, and the bottom end of the spring 82 is fixedly connected to the upper surface of the limiting plate 8. The fixed plate 81 and the spring 82 are set to limit the inclined state of the limiting plate 8, so that the limiting plate 8 maintains a state in which the distance between the limiting plate 8 and the upper surface of the heating inclined plate 6 gradually decreases from right to left. When the limiting plate 8 is forced to rotate upward, the spring 82 can be squeezed, so that the spring 82 is compressed to generate elastic potential energy. When the squeezing force on the limiting plate 8 disappears, the limiting plate 8 will complete the reset under the action of the elastic potential energy of the spring 82, and continue to limit the raw materials sliding down the heating inclined plate 6.

[0033] The right side of the heating box 5 is provided with a pushing unit, which includes a fixing frame 91, the fixing frame 91 is fixedly connected to the right side surface of the heating box 5, the right inner wall surface of the fixing frame 91 is fixedly connected with an electric push rod 92, the left end of the electric push rod 92 is fixedly connected with an inclined push plate 93, and the electric push rod 92 can drive the inclined push plate 93 to move linearly when it is started. The left end of the inclined push plate 93 passes through the heating box 5, and the left end of the inclined push plate 93 is inclined downward. The inclination angle of the inclined push plate 93 is the same as the inclination angle of the heating inclined plate 6, and the bottom surface of the inclined push plate 93 is aligned with the heating inclined plate 6. The upper surface of the inclined push plate 93 is located in the same horizontal plane. When the inclined push plate 93 moves to the left, it can push the raw materials that are blocked by the vertical plate 7 and fall on the right side of the heating inclined plate 6, so that the raw materials can be quickly unloaded. The right side surface of the inclined push plate 93 is fixedly connected to the limiting telescopic rod 94. The right end of the limiting telescopic rod 94 is fixedly connected to the right inner wall surface of the fixed frame 91. The limiting telescopic rod 94 can guide and limit the movement of the inclined push plate 93 to prevent the inclined push plate 93 from deviating and getting stuck during movement, and at the same time prevent the connection between the inclined push plate 93 and the electric push rod 92 from breaking.

[0034] When the raw materials are completely melted and discharged, the electric push rod 92 can be started to drive the inclined push plate 93 to continue to move to the left. At this time, the inclined push plate 93 can enter the gap between the limit plate 8 and the heating inclined plate 6, and scrape and push the molten raw materials attached to the upper surface of the heating inclined plate 6 and the bottom surface of the limit plate 8, thereby accelerating the discharge of the raw materials and avoiding the adhesion of the raw materials that prevent them from entering the machine body 1 for extrusion processing, affecting the utilization rate of the waste plastics.

[0035] Reference Figure 1 and Figure 3A discharge port 10 is provided on the left surface of the heating box 5, and a collecting hopper 11 is fixedly connected to the left end of the discharge port 10. The internal size of the collecting hopper 11 is adapted to the size of the discharge port 10, and the front and rear ends of the discharge port 10 are in contact with the front and rear inner wall surfaces of the heating box 5. The raw materials inside the heating box 5 can be completely discharged through the discharge port 10, and a connecting pipe 12 is fixedly connected to the left end of the collecting hopper 11. The bottom end of the connecting pipe 12 is fixedly connected to the upper surface of the machine body 1. After the raw materials are discharged through the discharge port 10, they can completely enter the collecting hopper 11 and completely enter the interior of the machine body 1 through the collecting hopper 11 for further processing, avoiding being obstructed by the inner wall of the heating box 5 and affecting the discharge efficiency and effect.

[0036] Working principle: The raw materials are put into the crusher 4 for shredding, and then the shredded raw materials can enter the heating box 5. At this time, the raw materials will be blocked by the vertical plate 7, so that the raw materials fall to the right end of the heating inclined plate 6. At this time, the raw materials will slide along the inclined surface of the heating inclined plate 6 into the gap between the heating inclined plate 6 and the limit plate 8. As the raw materials gradually melt and become smaller, they can flow through the gap between the heating inclined plate 6 and the limit plate 8 and slide to the discharge port 10. In the process of the raw materials entering the heating box 5, the electric push rod 92 can be started to drive the inclined push plate 93 to move slightly left and right. The raw materials are pushed to the right side of the heating inclined plate 6, accelerated to slide, and avoided to be blocked. When the raw materials are completely melted in the heating box 5, the electric push rod 92 can be started to drive the inclined push plate 93 to move continuously to the left, and the molten raw materials adhering to the upper surface of the heating inclined plate 6 and the bottom surface of the limit plate 8 are scraped and pushed, so as to reduce the situation that the raw materials are attached to the inside of the heating box 5 and cannot enter the inside of the machine body 1. When the raw materials slide to the left end of the heating inclined plate 6, they can enter the machine body 1 completely through the discharge port 10 and the collecting hopper 11 through the connecting pipe 12 for extrusion molding processing.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
