Description

Technical Field

[0001] This utility model belongs to the field of plastic remelting, specifically relating to a device for remelting waste materials from plastic processing. Background Technology

[0002] Plastic processing waste remelting equipment is a device specifically designed to process waste generated during plastic processing and remelt it for reuse. This device is of great significance in the field of plastic recycling and reuse, as it can effectively reduce the generation of plastic waste and improve resource utilization efficiency.

[0003] In existing plastic processing technologies, the scrap materials produced are uneven in size. Although plastic itself is flexible, the large scrap materials are prone to jamming when fed into the remelting device. At the same time, these large scrap materials will cause uneven heat distribution during the heating process, affecting the melting effect and equipment performance.

[0004] Therefore, a waste material remelting device for plastic processing is proposed, which has a crushing and feeding structure and multiple heating structures to improve the overall heating efficiency of the remelting device and solve the problems of blockage and uneven heat distribution during the use of existing waste material remelting devices. Utility Model Content

A discharge chute is opened through the left end of the transmission pipe. A feeding auger is installed inside the transmission pipe, with its outer wall fitting against the inner wall of the transmission pipe. A placement groove is opened on the outer wall of the transmission pipe, and a heating assembly is installed on the placement groove. A first rotating shaft is fixedly connected to the right end of the feeding auger, and a transmission assembly is installed through the right end of the first rotating shaft. A feeding chute is opened on the outer wall of the transmission pipe for feeding... A loading box is provided on the trough. A third support plate is fixed to the lower end of the loading box. A crusher is provided at the upper end of the loading box. A second motor is fixed to the left end of the loading box. The right end of the output shaft of the second motor extends into the interior of the loading box and is fixed to a third rotating column. A circularly distributed feeding hopper is fixed to the outer wall of the third rotating column. A brush is fixed to the end of the feeding hopper away from the axis of the third rotating column. A first trough is opened at the lower end of the loading box. The loading box and the feeding trough are interconnected inside the transmission pipe through the first trough and the feeding trough.

[0007] Preferably, the heating assembly includes heating blocks and an input end; two heating blocks are placed on the outer wall of the placement groove, the two heating blocks are hinged to each other on the upper part of the outer wall of the transmission tube, and the input end is provided at the end of the two heating blocks that are far apart from each other.

[0008] Preferably, the lower end of the transmission pipe is fixedly connected to a first support plate and a second support plate, and the left and right ends of the first support plate are provided with mounting grooves.

[0009] Preferably, the transmission assembly includes a first motor, a second rotating shaft, a second pulley, a transmission belt, and a first pulley; the first motor is fixedly connected to the inner wall of the mounting groove, the second rotating shaft is fixedly connected to the left end of the output shaft of the first motor, the second pulley is fixedly connected to the outer wall of the second rotating shaft, the first pulley is fixedly connected to the outer wall of the first rotating shaft, and the transmission belt is rotatably sleeved on the outer walls of the first pulley and the second pulley.

[0010] Preferably, the output end of the crusher faces the loading box, and the end of the brush away from the axis of the third rotating column is in contact with the lower end of the inner wall of the loading box.

[0011] Preferably, the feeding hopper is semi-cylindrical, and the inside of the feeding hopper is hollowed out.

[0012] Preferably, the transmission tube is made of a metal material with high thermal conductivity.

[0013] The beneficial effects of this utility model are as follows: By turning on the heating component, the residual material is then fed into the crusher for crushing. Then, the feeding hopper and brush rotate around the axis of the third rotating column, feeding the crushed residual material from the feeding trough into the feeding auger in the transmission pipe. The temperature of the transmission pipe drives the molten plastic on the feeding auger to feed to the left end of the transmission pipe. Then, through the force generated by the accumulation and extrusion, the molten plastic is squeezed out from the discharge trough. This solves the problem that in the existing remelting device, the residual material is too large, making it inconvenient to put in during the remelting process, and the melting is insufficient, causing blockages in the remelting process.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-4 This utility model provides an embodiment of a plastic processing waste material melting device, including a transmission pipe 1, a feeding hopper 107, and a transmission assembly. A discharge chute 2 is provided through the left end of the transmission pipe 1. A feeding auger 5 is installed inside the transmission pipe 1, with its outer wall fitting against the inner wall of the transmission pipe 1. A placement groove 4 is provided on the outer wall of the transmission pipe 1, and a heating assembly is installed on the placement groove 4. A first rotating shaft 6 is fixedly connected to the right end of the feeding auger 5, and the first rotating shaft 6 passes through the transmission pipe 1. A transmission assembly is provided at the right end of the transmission pipe 1. A feed trough 3 is provided on the outer wall of the transmission pipe 1. A loading box 102 is provided on the feed trough 3. A third support plate 101 is fixedly connected to the lower end of the loading box 102. A crusher 104 is provided at the upper end of the loading box 102. A second motor 105 is fixedly connected to the left end of the loading box 102. The right end of the output shaft of the second motor 105 extends into the interior of the loading box 102 and is fixedly connected to a third rotating column 106. A circular... The feeding hopper 107 is evenly distributed. A brush 108 is fixed to one end of the feeding hopper 107 away from the axis of the third rotating column 106. The lower end of the loading box 102 is provided with a first groove 103. The loading box 102 and the feeding groove 3 are interconnected inside the transmission pipe 1. By turning on the heating component, the residual material is fed into the crusher 104 for crushing. Then, the feeding hopper 107 and the brush 108 rotate around the axis of the third rotating column 106, and the crushed residual material is fed from the feeding groove 3 into the feeding auger 5 in the transmission pipe 1. The temperature of the transmission pipe 1 drives the molten plastic on the feeding auger 5 to feed to the left end of the transmission pipe 1. Then, the molten plastic is squeezed out from the discharge groove 2 by the force generated by the accumulation and extrusion. This solves the problem that the existing remelting device has problems such as the residual material being too large, making it inconvenient to put in during the remelting process, and insufficient melting, which leads to blockage during the remelting process.

[0021] Please see Figures 1-2In this embodiment, the heating assembly includes a heating block 15 and an input end 16. Two heating blocks 15 are placed on the outer wall of the placement groove 4. The two heating blocks 15 are hinged to each other on the upper part of the outer wall of the transmission tube 1. An input end 16 is provided at one end of the two heating blocks 15 that is far apart from each other. By placing the two heating blocks 15 on the placement groove 4 and then inserting the power cable into the input end 16 to supply power to the heating blocks 15, the heat generated by the heating blocks 15 heats the inner wall of the transmission tube 1. A first support plate 8 and a second support plate 10 are fixedly connected to the lower end of the transmission tube 1. Mounting grooves 9 are provided through the left and right ends of the first support plate 8. The device can be supported and placed by the first support plate 8 and the second support plate 10. The mounting grooves 9 are used to install subsequent transmission components. The transmission tube 1 is made of a metal material with high thermal conductivity, which facilitates the heating and melting of the plastic residue in the transmission tube 1.

[0022] Please see Figures 2-3 In this embodiment, the transmission assembly includes a first motor 11, a second rotating shaft 12, a second pulley 13, a transmission belt 14, and a first pulley 7. The first motor 11 is fixedly connected to the inner wall of the mounting groove 9. The second rotating shaft 12 is fixedly connected to the left end of the output shaft of the first motor 11. The second pulley 13 is fixedly connected to the outer wall of the second rotating shaft 12. The first pulley 7 is fixedly connected to the outer wall of the first rotating shaft 6. The transmission belt 14 is rotatably sleeved on the outer walls of the first pulley 7 and the second pulley 13. The transmission assembly drives the subsequent feeding auger 5 to rotate and extrude material on the inner wall of the transmission pipe 1.

[0023] Please see Figures 3-4 In this embodiment, the output end of the crusher 104 faces the loading box 102, and the end of the brush 108 away from the axis of the third rotating column 106 is attached to the lower end of the inner wall of the loading box 102. By feeding the residual material into the top of the crusher 104, the residual material crushed by the crusher 104 falls into the loading box 102. The crushed residual material on the loading box 102 is fed into the transmission pipe 1 through the feeding chute 3 by the feeding hopper 107 and the brush 108, thereby performing the feeding work. The feeding hopper 107 is semi-cylindrical, and the inside of the feeding hopper 107 is hollowed out to store some of the residual material falling into the feeding hopper 107. When the feeding hopper 107 is rotated by the third rotating column 106, the material is fed into the transmission pipe 1.

[0024] When it is necessary to remelt the waste material from plastic processing, the input terminal 16 is electrically connected to the power supply terminal. Then, the heating output terminal of the heating block 15, located near the axis of the transmission pipe 1, heats the outer wall of the left end of the transmission pipe 1. Next, the first motor 11 is turned on, causing its output shaft to drive the second rotating shaft 12 to rotate. This causes the second pulley 13 to rotate, which in turn drives the first pulley 7 to rotate via the transmission belt 14. Then, the first rotating shaft 6 drives the feeding auger 5 to rotate on the inner wall of the transmission pipe 1. Finally, the waste material from plastic processing is fed into the upper part of the crusher 104, where it is crushed. The material falls into the loading box 102. Then, the output shaft of the second motor 105 is turned on to drive the feeding hopper 107 on the outer wall of the third rotating column 106 to rotate. Some of the excess material falls onto the feeding hopper 107. The centrifugal force generated by the rotation drives the material on the feeding hopper 107 into the transmission pipe 1 through the feeding trough 3 and onto the outer wall of the feeding auger 5. The material falling onto the lower end of the inner wall of the loading box 102 is fed into the transmission pipe 1 through the feeding trough 3 by the brush 108. The excess plastic material melts at the temperature at the left end of the transmission pipe 1. Then, by rotating the feeding auger 5, the melted excess material is accumulated at the left end of the transmission pipe 1 and then squeezed out from the discharge trough 2.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
