Description

Technical Field

[0001] The invention relates to the field of plastic recycling, and in particular to a plastic bottle recycling and reuse processing device. Background Art

[0002] When recycling plastic bottles, the collected plastic bottles must first be crushed. Since plastic bottles are generally used to hold liquids, there will inevitably be residual liquid in the collected plastic bottles. In addition, the tightness of the bottle caps of the plastic bottles is also unpredictable. Therefore, in the plastic crushing process, not only the impact of the residual liquid in the bottle must be considered, but also the bottle is filled with gas but the bottle cap is loosely screwed. When crushing, the cutter will cause the plastic bottle to dent before cutting open the plastic bottle, and the air pressure in the bottle will increase, which can easily cause the bottle cap to fly out.

[0003] Based on the above search, some prior arts were found, which are introduced one by one:

[0004] First, the Chinese invention patent application with application publication number CN108688011A discloses a plastic bottle recycling puncturing device, which punctures the plastic bottle with a puncture needle, and then gradually squeezes the plastic bottle with a roller to squeeze out the air and liquid in the bottle through the punctured through hole. Although this method can solve the impact of residual liquid and gas in the bottle, it also has some shortcomings: when the liquid is squeezed out by rolling, the rolling speed of the roller is relatively slow, the efficiency is low, and it is difficult to squeeze out the residual liquid completely, and the effect is poor;

[0005] Secondly, the Chinese utility model patent with authorization announcement number CN214562193U discloses a waste plastic recycling device with a classification function, which directly cuts plastic bottles by the cooperation of a cutting blade and spikes. The function of the spikes is to cooperate with the cutting blade to cut the plastic bottles. Therefore, the impact of air in the bottle on the cutting is not solved. In addition, after cutting, the plastic fragments are turned over in the filter cartridge to filter the residual liquid. In essence, solid-liquid separation is achieved by filtration, and there are also problems of low efficiency and poor effect.

[0006] In addition, the above two prior arts both have the following problems: different plastic bottles are made of different materials, for example, beverage bottles, oil bottles, etc. use different plastic materials. When recycling, the plastic bottles need to be sorted, which is troublesome and cumbersome.

The advantages of this are: since the plastic bottle is punctured before cutting, the air in the plastic bottle and the tightening degree of the bottle cap will not affect the cutting of the plastic bottle; since the plastic bottle is punctured in advance, during the dehydration process, on the one hand, the efficiency of centrifugal dehydration is higher, and on the other hand, the plastic fragments punctured with a plurality of holes are equivalent to pieces of hollow fragments. During centrifugation, liquid can be thrown out through the holes. If there are no holes, the liquid on the plastic fragments is difficult to be thrown out, so the centrifugal dehydration effect is better; since the weight of plastic fragments of different materials is different, the screening member 300 classifies and outputs the plastic fragments by hot air screening, and the hot air can further dry the plastic fragments.

[0037] Cutting mechanism 100:

[0038] Reference Figure 2-Figure 7 The cutting mechanism 100 includes a base 102 and a first motor 103. A cover 101 is provided on the upper end surface of the base 102. A rotating column 109 is rotatably installed in the cover 101, and a first rotating shaft formed at the rotating installation position is dynamically connected to the first motor 103.

[0041] When in use, a plastic bottle is put into the through hole 1091 through the input tube 106, and then the rotating column 109 is driven by the first motor 103 to rotate ninety degrees, the plastic bottle is punctured by the puncturing component 107, and then the rotating column 109 is rotated ninety degrees again, and the plastic bottle is cut by the cutting component 108, and then the rotating column 109 is rotated ninety degrees again, and the cut plastic fragments are output through the output hole 1021, and this reciprocating process has the advantage that the plastic bottle can be put in, punctured, cut and the plastic fragments can be output at the same time, so the efficiency is relatively high.

[0044] In a preferred embodiment, during the resetting process, it is easy for the plastic bottle to get hung on the needle 1075. Therefore, initially, the bottom of the needle 1075 is flush with the upper end of the rotating column 109. Therefore, even if this situation occurs, the plastic bottle will be pushed down when the rotating column 109 rotates subsequently.

[0046] A push rod 1086 is sleeved in each perforation 1088. Initially, the bottom of the push rod 1086 is flush with the bottom of the blade. The upper ends of all the push rods 1086 are connected by a slide seat 1085. The slide seat 1085 and the guide rod 1083 form a sliding connection. The outer part of the guide rod 1083 is sleeved with a second spring 1087 located between the slide seat 1085 and the connecting seat 1082; the connecting seat 1082 is driven downward by the second telescopic rod, and the connecting seat 1082 moves downward with the cutting tool 1084 and the push rod 1086. When the cutting tool 1084 cuts the plastic bottle, the push rod 1086 is blocked by the plastic bottle and does not move. The second spring 1087 is compressed, and the cut plastic fragments are located in the grid of the cutting tool 1084. After the cutting is completed, the second telescopic rod drives the connecting seat 1082 to move upward, and the cutting assembly 108 is reset. At the same time, the push rod 1086 will push out the plastic fragments in the grid.

[0047] Dehydration element 200:

[0048] Reference Figure 1 and Figure 8 The dehydration component 200 includes a second motor 203 and a fixed tube 201 arranged at the lower hole of the output hole 1021. The movable tube 202 is rotatably installed in the fixed tube 201, and the second rotating shaft formed at the rotating installation position is dynamically connected to the second motor 203. The second rotating shaft is arranged horizontally. One end of the movable tube 202 is open and the other end is closed. The outer circular surface of the movable tube 202 is provided with a drainage nozzle 2021 close to the closed end. The second motor 203 can drive the movable tube 202 to rotate, so that the opening of the movable tube 202 can be facing upward or downward.

[0049] A dehydration barrel 204 is rotatably installed in the movable tube 202, and a third rotating shaft formed at the rotating installation position is dynamically connected to a third motor 205 arranged in the movable tube 202. Initially, the third rotating shaft is coaxial with the fixed tube 201, and a plurality of dehydration holes are arranged in an array on the outer circular surface of the dehydration barrel 204.

[0050] After the cut plastic fragments fall into the dehydration barrel 204, the third motor 205 drives the dehydration barrel 204 to rotate at high speed. Under the action of centrifugal force, the liquid on the plastic fragments is thrown out and finally output through the drainage nozzle 2021. After the dehydration is completed, the second motor 203 drives the movable tube 202 to rotate, so that the openings of the movable tube 202 and the dehydration barrel 204 are both facing downward, and the dehydrated plastic fragments fall.

Preferably, the material guide pipe 303 is arranged at an angle, and the distance between the material guide pipe 303 and the upper surface of the air duct 301 decreases along the wind direction of the fan 302. The cross-sectional size of the material guide pipe 303 decreases downward, which is significant in that the plastic fragments fall smoothly and smoothly into the air duct 301 at a slower speed.

[0054] A discharge pipe 304 is disposed on the lower surface of the wind channel 301 , and a plurality of discharge pipes 304 are disposed along the wind direction of the fan 302 .

[0055] After the plastic fragments fall into the guide pipe 303, they are blown by the wind, so the plastic fragments fall into different discharge pipes 304 according to their weight, that is, the plastic fragments are classified and discharged.
