Description

Technical Field

[0001] The invention relates to the technical field of plastic product recycling, and in particular to a plastic waste recycling device. Background Art

[0002] The widespread use of plastic products in production and life has led to the generation of a large amount of plastic waste. If these wastes are not properly handled, they will seriously pollute the environment, occupy precious land resources, and waste renewable resources. Therefore, it is particularly important to develop efficient plastic waste recycling equipment. Plastic waste recycling equipment uses physical treatment technology to efficiently classify, crush, clean and recycle various types of plastic waste to achieve resource recycling. Its core function is to convert plastics that were originally regarded as waste into valuable recycled materials, which not only reduces environmental pollution, but also promotes the sustainable use of resources, and provides strong support for building a green, low-carbon circular economy system.

[0037] like Figures 1 to 8 As shown, an upper rotating disk 116 is fixedly connected to the first spur gear 102, and a lower rotating disk 117 is fixedly connected to the second spur gear 113. The upper rotating disk 116 and the lower rotating disk 117 are both rotatably mounted inside the side support plate 101.

The transmission gear 114 is meshed with the first spur gear 102, and the first spur gear 102 is meshed with the second spur gear 113. The two side support plates 101 are connected together, one side of each of the two side support plates 101 is fixedly connected to a limit plate 103, a movable block 104 is slidably sleeved on the limit plate 103, a movable rod 105 is slidably connected inside the movable block 104, an upper cutting tool 106 and a lower cutting tool 107 are slidably sleeved on the two movable rods 105, two ends of the upper cutting tool 106 are movably hinged to one side of the two upper turntables 116, and two ends of the lower cutting tool 107 are movably hinged to one side of the two lower turntables 117.

[0038] like Figures 1 to 8As shown, two symmetrically arranged lower connecting rods 108 are fixedly provided at the bottom of the lower cutting tool 107, four symmetrically arranged pull plates 110 are fixedly connected to the two lower connecting rods 108, and a slider 112 is fixedly connected to the pull plate 110. Two symmetrically arranged guide plates 109 are slidably provided on the two side support plates 101, guide grooves 111 are opened inside the two guide plates 109, and two sliders 112 are slidably connected inside the guide grooves 111. Output shafts 118 are rotatably installed inside the two fixed plates 8, and the output shaft 118 and the first rotating rod 115 are jointly sleeved with a first synchronous belt 122 through a synchronous wheel.

[0039] like Figures 1 to 8 As shown, two symmetrically arranged connecting rollers 124 are rotatably installed on the two fixed plates 8, and two symmetrically arranged moving grooves are provided inside the two fixed plates 8, wherein the two connecting rollers 124 are slidably connected inside the moving grooves, and a slide plate 125 is slidably connected to the two fixed plates 8, and a transmission rod 121 is rotatably installed on the slide plate 125, and a tensioning wheel 123 is movably provided on the two fixed plates 8, and the transmission rod 121, the tensioning wheel 123, the output shaft 118 and the two connecting rollers 124 provided on one of the fixed plates 8 are jointly sleeved with a first conveyor belt 119, and the transmission rod 121, the tensioning wheel 123, the output shaft 118 and the two connecting rollers 124 provided on the other fixed plate 8 are jointly sleeved with a second conveyor belt 120, and one of the guide plates 109 is fixedly connected to the connecting roller 124 slidably connected inside the moving groove.

[0040] In this embodiment, when recycling plastic waste, first, the recycling device is started by the controller 5 installed on the metal housing 4, and then the plastic waste to be recycled is placed on the first conveyor belt 119 in an orderly manner, and the output end of the motor is coaxially connected with the output shaft 118 rotating on the fixed plate 8 through a coupling, and the controller 5 starts the motor to drive the output shaft 118 to rotate. The output source can be flexibly selected and is not limited to the motor. The corresponding output source can be set according to the actual situation;

[0041] As the output shaft 118 rotates, through the transmission action of the first synchronous belt 122, the first rotating rod 115 and the transmission gear 114 on the two side support plates 101 rotate synchronously, and the transmission gear 114 meshes with the first spur gear 102, thereby driving the first spur gear 102 and the second spur gear 113 to rotate together. Because the first spur gear 102 and the second spur gear 113 are meshed and connected, this rotation process simultaneously drives the rotation of the upper turntable 116 and the lower turntable 117. The upper turntable 116 is connected to one end of the upper cutting tool 106 through the movable hinge point thereon. When the upper turntable 116 rotates driven by the motor, the upper cutting tool 106 reciprocates up and down through the movable hinge point. Because the movable rod 105 slides through the movable block 104 and the upper cutting tool 106, the upper cutting tool 106 can move up and down along the axial direction of the movable rod 105, ensuring that the upper cutting tool 106 can realize the reciprocating cutting action up and down with the rotation of the upper turntable 116;

[0042] Correspondingly, the lower turntable 117 is also connected to the lower cutting tool 107 by the same movable hinge mode. It should be noted that the movement direction of the lower cutting tool 107 is opposite to that of the upper cutting tool 106. When the upper cutting tool 106 moves upward, the lower cutting tool 107 moves downward. This reverse movement is achieved by the lower turntable 117 rotating in opposite directions to the upper turntable 116, ensuring that the two can effectively cut the plastic waste when moving toward each other, thereby achieving equidistant cutting of the plastic waste. In the subsequent crushing process, due to the uniform size, it can be processed more quickly, realizing automated and continuous operation, and the subsequent processing links are carried out smoothly, reducing manual intervention and downtime;

[0043] In addition, because the upper cutting tool 106 and the lower cutting tool 107 are arranged between the first conveyor belt 119 and the second conveyor belt 120, the two conveyor belts are telescopic, so as to adapt to the dynamic changes in the fertilizer cutting process. Specifically, the telescopic conveyor belt is composed of two symmetrically arranged tensioning wheels 123, two slidable connecting rollers 124, a slide plate 125, a transmission rod 121 and a conveyor belt body. The connecting roller 124 close to the cutting tool can slide in the movable groove on the fixed plate 8, so that the conveyor belt can be adjusted in length as needed;

[0044] During the cutting process, when the lower cutting tool 107 pulls the guide plate 109 through the lower connecting rod 108 and the slider 112 at the bottom thereof, the movement of the guide plate 109 will further drive the connecting roller 124 fixedly connected thereto to slide in the moving groove. Since the connecting roller 124 is a part of the transmission structure of the conveyor belt, it will directly act on the conveyor belt when it is displaced. The first conveyor belt 119 and the second conveyor belt 120 will move closer to the cutting tool in the cutting area accordingly, ensuring that the waste can smoothly transfer from the first conveyor belt 119 to the second conveyor belt 120 after the cutting is completed, thereby avoiding the accumulation or dislocation of the waste during the cutting process.

[0045] As the cutting tool reciprocates up and down, the telescopic conveyor adjusts its length as needed, thereby improving the efficiency and accuracy of waste recycling. Through the above steps, plastic waste is efficiently and accurately cut and transferred to the next processing stage. The recycling process is automated and continuous, improving recycling efficiency and resource utilization.

[0046] Example 2

[0047] like Figures 1 to 8 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that two symmetrically arranged high support rods 201 and two symmetrically arranged low support rods 209 are fixedly arranged inside the metal shell 4, the two high support rods 201 are each provided with a first straight groove 211, the two low support rods 209 are each provided with a second straight groove 212, the two first straight grooves 211 and the two second straight grooves 212 are slidably connected to a screen frame 202, and the screen frame 202 and the bottom walls of the two first straight grooves 211 and the two second straight grooves 212 are commonly connected to a vibration spring 207.

[0048] like Figures 1 to 8 As shown, a side plate 210 is fixedly provided inside the metal shell 4, a rotating shaft 205 is rotatably installed inside the side plate 210, a cam 206 is fixedly sleeved on the outer circumference of the rotating shaft 205, the rotating shaft 205 and one of the connecting rollers 124 are jointly sleeved with a second synchronous belt 208 through a synchronous wheel, and the cam 206 is located below the screen frame 202.

[0049] In this embodiment, the plastic waste after equidistant cutting is transferred to the second conveyor belt 120. The second conveyor is an independent conveying unit, and its power comes from one of the connecting rollers 124 directly connected to the output end of the motor through a coupling. The second conveyor belt 120 moves and drives the waste to move together, ensuring that the waste can continue to move to the position of the screen frame 202. The waste is put into the screen frame 202 in an orderly manner. At this time, the rotating shaft 205 and the connecting roller 124 connected to the motor on the second conveyor belt 120 are connected by The second synchronous belt 208 is connected to realize the synchronous rotation of the rotating shaft 205 and the connecting roller 124. As the rotating shaft 205 rotates, the cam 206 fixed thereon also rotates. The rotational movement of the cam 206 intermittently pushes the screen frame 202 upward. Because the four sides of the screen frame 202 are respectively slidably arranged in the first straight groove 211 of the high support rod 201 and the second straight groove 212 of the low support rod 209, and are connected to the bottom wall through the vibration spring 207, the screen frame 202 generates a vibration effect under the action of the cam 206;

[0050] During the vibration of the screen frame 202, metal impurities and dust contained in the plastic waste are separated, and the separated plastic waste falls into the steel housing 213 located on one side of the screen frame 202 and enters the next stage of crushing treatment, thereby improving the efficiency of the crushing process and avoiding damage to the crushing roller 203 caused by the presence of impurities or metals, thereby extending the service life of the crushing equipment;

[0051] Furthermore, two metal rotating cylinders 204 are symmetrically arranged inside the steel shell 213, and a crushing roller 203 is installed on each metal rotating cylinder 204. When the plastic waste enters the steel shell 213, the two crushing rollers 203 start to rotate under the action of the driving source to thoroughly crush the waste. A special output device is provided inside the steel shell 213 to ensure the stable operation of the crushing rollers 203 and crush the plastic waste.

[0052] Example 3

[0053] like Figures 1 to 8 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a material trough is opened inside the material bin 6, the upper extrusion block 303 and the lower extrusion block 304 are both slidably connected inside the material trough, the upper extrusion block 303 is movably hinged with a first pull rod 308, and the lower extrusion block 304 is movably hinged with a second pull rod 309, and a connecting plate 307 is rotatably installed inside the metal shell 4, and the first pull rod 308 and the second pull rod 309 are both movably hinged with the connecting plate 307.

[0054] like Figures 1 to 8As shown, a round rod 305 is fixedly nested inside the connecting plate 307, a base 301 is fixedly arranged inside the metal shell 4, and a plurality of equidistantly arranged conveying rollers 302 are installed inside the base 301, a transmission shaft 310 is fixedly nested inside one of the conveying rollers 302, and the transmission shaft 310 and the round rod 305 are jointly sleeved with a third synchronous belt 306 through a synchronous wheel.

[0055] In this embodiment, after the crushing process is completed, the waste falls through the discharge port opened on one side of the steel shell 213, and the waste falls directly on the conveying roller 302 located on the base 301. The conveying roller 302 group transports the waste to the entrance of the silo 6. It should be noted that the top of the conveying roller 302 is connected to the opening at the bottom of the silo 6. The waste enters the silo 6, and the extrusion mechanism inside the silo 6 is started immediately. Specifically, a transmission shaft 310 fixedly nested inside one of the conveying rollers 302 is mutually sleeved with the round rod 305 through the third synchronous belt 306. As the transmission shaft 310 rotates, the round rod 305 also rotates synchronously, driving the connecting plate 307 to rotate together. During the rotation of the connecting plate 307, the first pull rod 308 and the second pull rod 309 movably hinged therewith are driven to reciprocate;

[0056] Furthermore, the first pull rod 308 and the second pull rod 309 are movably hinged with the upper extrusion block 303 and the lower extrusion block 304 respectively, and the upper extrusion block 303 and the lower extrusion block 304 are designed to be slidably connected inside the silo 6. Therefore, with the movement of the pull rod, the upper extrusion block 303 and the lower extrusion block 304 will reciprocate along the axial direction of the silo 6, and the upper extrusion block 303 and the lower extrusion block 304 implement extrusion and pushing of the waste in the silo 6. As the waste continues to accumulate, the pressure on it gradually increases, thereby achieving a compression effect on the waste. After the waste is recovered, the alloy material taking door 7 is opened to take it out, thereby improving the storage efficiency of the waste;

[0057] It should be noted that the output sources such as motors are intelligently regulated by the controller 5 , and the output sources are all electrically connected to the controller 5 , and the corresponding parameters can be directly input into the controller 5 before recycling.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
