Description

Technical Field

[0001] This invention relates to the field of plastic recycling, and more specifically to a plastic bottle recycling and reuse processing device. Background Technology

[0002] When recycling plastic bottles, the first step is to crush them. Since plastic bottles are generally used to hold liquids, residual liquid is inevitable. In addition, the tightness of the bottle caps is unpredictable. Therefore, during the crushing process, it is necessary to consider not only the impact of residual liquid but also the fact that the bottle is filled with gas but the cap is loosely screwed on. During crushing, the plastic bottle may dent before the cutter cuts it open, causing the internal pressure to increase and potentially causing the cap to fly off.

[0003] Based on the above search, some existing technologies were found, which will be introduced one by one:

[0004] Firstly, Chinese invention patent application CN108688011A discloses a plastic bottle recycling perforation device. This device punctures the plastic bottle and then uses a roller to gradually squeeze the bottle, expelling the air and liquid inside through the punctured holes. While this method can address the issue of residual liquid and gas inside the bottle, it also has some drawbacks: the rolling speed of the roller is relatively slow, resulting in low efficiency, and it is difficult to completely expel the residual liquid, leading to poor performance.

[0005] Secondly, the Chinese utility model patent with authorization announcement number CN214562193U discloses a waste plastic recycling device with sorting function. It directly cuts plastic bottles by the cooperation of cutting blades and spikes. The spikes are used to cut the plastic bottles in conjunction with the cutting blades. Therefore, it does not solve the problem of the influence of air inside the bottle on the cutting. In addition, after cutting, the plastic fragments are turned over in the filter cartridge to filter the residual liquid. Essentially, it still achieves solid-liquid separation through filtration, which also has the problems of low efficiency and poor effect.

[0006] In addition, both of the above-mentioned existing technologies have the following problems: different plastic bottles are made of different materials, such as beverage bottles and oil bottles, which are made of different plastic materials. When recycling, plastic bottles need to be sorted, which is quite troublesome and cumbersome.

[0007] Based on the above, the present invention proposes a plastic bottle recycling and reuse processing device. Summary of the Invention

[0008] To address the problems mentioned in the background above, the present invention provides a plastic bottle recycling and reuse processing device.

[0009] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0010] A plastic bottle recycling and reuse processing device includes a cutting mechanism, a dehydration component, and a screening component. The cutting mechanism is used to puncture and cut the plastic bottle, the dehydration component is used to centrifuge and dehydrate the cut plastic fragments, and the screening component is used to screen and classify the centrifuged and dehydrated plastic fragments.

[0011] The cutting mechanism includes a base and a first motor. A cover is provided on the upper end face of the base. A rotating column is rotatably installed inside the cover, and a first rotating shaft formed at the rotatable installation point is connected to the first motor. A through hole is provided through the end face of the rotating column, and at least four through holes are arranged in an array along the circumference of the rotating column.

[0012] The upper closed end of the cover is provided with three upper holes. A first mounting tube is provided at the opening of one upper hole, and a piercing component is provided on the first mounting tube. A second mounting tube is provided at the opening of one upper hole, and a cutting component is provided on the second mounting tube. An input tube is provided at the opening of the last upper hole. An output hole is provided on the end face of the base. Initially, the output hole and the three upper holes are connected to the four through holes respectively.

[0013] As a further improvement and optimization of the present invention, the piercing assembly includes a first telescopic rod arranged vertically, a first connecting rod provided at the output end of the first telescopic rod, a pressure seat provided at the bottom of the first connecting rod, the pressure seat being located inside the first mounting tube, a piercing seat provided on the outside of the first connecting rod, a plurality of piercing needles arranged in an array on the lower end face of the piercing seat, and a clearance hole provided on the pressure seat for avoiding the piercing needles.

[0014] As a further improvement and optimization of the present invention, the spike seat and the first connecting rod are slidably connected, and a fixing ring is provided on the first connecting rod above the spike seat. A first spring is sleeved on the outside of the first connecting rod between the spike seat and the fixing ring.

[0015] As a further improvement and optimization of the present invention, the cutting assembly includes a second telescopic rod arranged vertically, a second connecting rod provided at the output end of the second telescopic rod, a connecting seat provided at the bottom of the second connecting rod, a guide rod arranged vertically at the bottom of the connecting seat, and a cutting tool provided at the bottom of the guide rod.

[0016] As a further improvement and optimization of the present invention, the cutting tool includes a tool holder connected to the guide rod, and the lower end face of the tool holder is provided with a plurality of blades arranged in a crisscross pattern, the plurality of blades correspondingly forming a plurality of grids.

[0017] As a further improvement and optimization of the present invention, the tool holder is provided with a through hole, which is connected to the grid. Multiple through holes are provided, and a push rod is fitted in each through hole. Initially, the bottom of the push rod is flush with the bottom of the blade. The upper ends of all the push rods are connected by a slide block. The slide block and the guide rod form a sliding connection. A second spring is fitted on the outside of the guide rod between the slide block and the connecting seat.

[0018] As a further improvement and optimization of the present invention, the dehydration component includes a second motor and a fixed pipe disposed at the lower opening of the output hole. A movable pipe is rotatably installed inside the fixed pipe, and a second rotating shaft formed at the rotatable installation location is connected to the second motor. The second rotating shaft is arranged horizontally. One end of the movable pipe is open and the other end is closed, and a drain nozzle is provided on the outer circular surface of the movable pipe near the closed end.

[0019] A dehydration bucket is rotatably installed inside the movable tube, and a third rotating shaft formed at the rotatable installation point is connected to a third motor installed inside the movable tube. Initially, the third rotating shaft is coaxial with the fixed tube, and the outer circular surface of the dehydration bucket is arrayed with several dehydration holes.

[0020] As a further improvement and optimization of the present invention, the screening component includes a horizontally arranged air channel, one end of which is equipped with a fan and the other end with a screen. The upper surface of the air channel is provided with a guide pipe connected to the lower opening of the fixed pipe, and the lower surface of the air channel is provided with a discharge pipe. Multiple discharge pipes are arranged along the wind direction of the fan.

[0021] As a further improvement and optimization of the present invention, the guide pipe is arranged at an angle, the distance between the guide pipe and the upper surface of the air channel decreases along the wind direction of the fan, and the cross-sectional dimensions of the guide pipe decrease downwards.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows:

[0023] In this solution, because the plastic bottle is perforated before cutting, the air inside the bottle and the tightness of the cap will not affect the cutting process. Because the plastic bottle is perforated beforehand, the centrifugal dehydration efficiency is higher during the dehydration process. Furthermore, the perforated plastic fragments act like hollowed-out pieces, allowing liquid to be ejected through the holes during centrifugation. Without the holes, the liquid on the plastic fragments would be difficult to eject, thus improving the centrifugal dehydration effect. Since the weight of plastic fragments varies depending on the material, the screening component uses hot air to classify and output the fragments, and the hot air further dries them.

Detailed Implementation

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] Reference Figures 1-9A plastic bottle recycling and reuse processing device includes a cutting mechanism 100, a dehydration component 200, and a screening component 300. The cutting mechanism 100 is used to puncture and cut the plastic bottle. The dehydration component 200 is used to centrifuge and dehydrate the cut plastic fragments. The screening component 300 is used to screen and classify the centrifuged and dehydrated plastic fragments. The advantages of this method are: because the plastic bottle is punctured before cutting, the air inside the bottle and the tightness of the cap will not affect the cutting process; because the plastic bottle is punctured beforehand, the centrifugal dehydration efficiency is higher; furthermore, the plastic fragments with several holes are like perforated fragments, allowing liquid to be ejected through the holes during centrifugation. Without holes, the liquid on the plastic fragments would be difficult to eject, thus improving the centrifugal dehydration effect; since the weight of plastic fragments of different materials varies, the screening component 300 uses hot air screening to classify and output the plastic fragments, and the hot air can further dry the plastic fragments.

[0037] Cutting mechanism 100:

[0038] Reference Figures 2-7 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 inside the cover 101, and a first rotating shaft formed at the rotatable installation point is connected to the first motor 103. The first motor 103 can drive the rotating column 109 to rotate. A through hole 1091 is provided through the end face of the rotating column 109. At least four through holes 1091 are arranged in an array along the circumferential direction of the rotating column 109.

[0039] The upper closed end of the cover 101 is provided with three upper holes. A first mounting tube 104 is provided at the opening of one upper hole, and a piercing component 107 is provided on the first mounting tube 104. A second mounting tube 105 is provided at the opening of one upper hole, and a cutting component 108 is provided on the second mounting tube 105. An input tube 106 is provided at the opening of the last upper hole.

[0040] The end face of the base 102 is provided with an output hole 1021. Initially, the output hole 1021 and the three upper holes are connected to the four through holes 1091 respectively.

[0041] In use, a plastic bottle is inserted into the through hole 1091 through the input pipe 106. Then, the first motor 103 drives the rotating column 109 to rotate 90 degrees, and the plastic bottle is pierced by the piercing component 107. Then, the rotating column 109 rotates 90 degrees again, and the plastic bottle is cut by the cutting component 108. Then, the rotating column 109 rotates 90 degrees again, and the cut plastic fragments are output through the output hole 1021. This process is repeated. The advantage is that plastic bottle insertion, piercing, cutting, and plastic fragment output are performed simultaneously, so the efficiency is high.

[0042] Reference Figure 4 and Figure 5 The piercing assembly 107 includes a first telescopic rod arranged vertically, which can be an electric telescopic rod or a hydraulic telescopic rod. The output end of the first telescopic rod is provided with a first connecting rod 1071, and the bottom of the first connecting rod 1071 is provided with a pressure seat 1072, which is located inside the first mounting tube 104.

[0043] A spike seat 1073 is sleeved on the outside of the first connecting rod 1071. A first spring 1074 is provided between the spike seat 1073 and a fixing ring located on the first connecting rod 1071 and above the spike seat 1073. A plurality of spikes 1075 are arranged in an array on the lower end face of the spike seat 1073. A relief hole is provided on the pressure seat 1072 to avoid the spikes 1075. The first connecting rod 1071 is driven to move downward by the first telescopic rod. The first connecting rod 1071 will move downward along with the pressure seat 1072 and the spike seat 1073, so that the spikes 1075 pierce the plastic bottle. After that, the spikes 1075 contact the base 102 and do not move. The pressure seat 1072 continues to move downward, the first spring 1074 is compressed, and the plastic bottle is crushed by the pressure seat 1072 to expel air. After that, the second telescopic rod drives the first connecting rod 1071 to move upward, so that the piercing assembly 107 is reset.

[0044] In a preferred embodiment, during the reset process, the plastic bottle may get caught on the needle 1075. Therefore, initially, the bottom of the needle 1075 is flush with the top of the rotating column 109. So even if this happens, the plastic bottle will be pushed down when the rotating column 109 rotates.

[0045] Reference Figure 4 , Figure 6 and Figure 7The cutting assembly 108 includes a vertically arranged second telescopic rod, the output end of which is provided with a second connecting rod 1081, the bottom of which is provided with a connecting seat 1082, the bottom of which is provided with a vertically arranged guide rod 1083, and the bottom of which is provided with a cutting tool 1084. Further, the cutting tool 1084 includes a tool holder connected to the guide rod 1083, the lower end face of which is provided with a plurality of blades arranged in a crisscross pattern and correspondingly forming a plurality of grids, and the tool holder is provided with through holes 1088 that communicate with the grids, and there are a plurality of through holes 1088.

[0046] Each perforation 1088 is fitted with a push rod 1086. Initially, the bottom of the push rod 1086 is flush with the bottom of the blade. The upper ends of all push rods 1086 are connected by a slide block 1085. The slide block 1085 and the guide rod 1083 are slidably connected. A second spring 1087 is fitted on the outside of the guide rod 1083 between the slide block 1085 and the connecting seat 1082. The connecting seat 1082 is driven to move down by the second telescopic rod. The downward movement of the connecting seat 1082 moves the cutting blade 1084 and the push rods 1086 down together. When the cutting blade 1084 cuts the plastic bottle, the push rod 1086 is obstructed by the plastic bottle and does not move. The second spring 1087 is compressed. The cut plastic fragments are located in the grid of the cutting blade 1084. After the cutting is completed, the second telescopic rod drives the connecting seat 1082 to move up, the cutting assembly 108 is reset, and at the same time, the push rod 1086 pushes the plastic fragments in the grid out.

[0047] Dehydration component 200:

[0048] Reference Figure 1 and Figure 8 The dehydration component 200 includes a second motor 203 and a fixed pipe 201 disposed at the lower opening of the output hole 1021. A movable pipe 202 is rotatably installed inside the fixed pipe 201, and a second rotating shaft formed at the rotatable installation location is poweredly connected to the second motor 203. The second rotating shaft is arranged horizontally. One end of the movable pipe 202 is open and the other end is closed, and a drain nozzle 2021 is provided on the outer circular surface of the movable pipe 202 near the closed end. The second motor 203 can drive the movable pipe 202 to rotate, thereby enabling the opening of the movable pipe 202 to face upward or downward.

[0049] A dehydration bucket 204 is rotatably installed inside the movable tube 202, and a third rotating shaft formed at the rotatable installation point is connected to a third motor 205 installed inside the movable tube 202. Initially, the third rotating shaft is coaxial with the fixed tube 201, and a number of dehydration holes are arranged on the outer circular surface of the dehydration bucket 204.

[0050] After the cut plastic fragments fall into the dehydration tank 204, the dehydration tank 204 is driven to rotate at high speed by the third motor 205. Under the action of centrifugal force, the liquid on the plastic fragments is thrown out and finally discharged through the drain nozzle 2021. After dehydration, the movable tube 202 is driven to rotate by the second motor 203, so that the openings of the movable tube 202 and the dehydration tank 204 are both facing downwards, and the dehydrated plastic fragments fall off.

[0051] Screening component 300:

[0052] Reference Figure 1 and Figure 9 The screening component 300 includes a horizontally arranged air duct 301. One end of the air duct 301 is provided with a fan 302 and the other end is provided with a mesh cover. Preferably, the air generated by the fan 302 can be heated by existing electric heating technology to obtain hot air.

[0053] The upper surface of the air duct 301 is provided with a guide pipe 303 connected to the lower opening of the fixed pipe 201. Preferably, the guide pipe 303 is arranged at an angle, and the distance between the 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 guide pipe 303 decreases downward. The purpose of this is to allow the plastic fragments to fall smoothly and slowly into the air duct 301.

[0054] The lower surface of the air duct 301 is provided with a discharge pipe 304, and multiple discharge pipes 304 are provided along the wind direction of the fan 302.

[0055] After the plastic fragments fall into the feed pipe 303, they are blown by the wind. Therefore, according to their weight, the plastic fragments fall into different discharge pipes 304, which means that the plastic fragments are sorted and output.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
