Description

Technical Field

[0001] The invention belongs to the technical field of non-metallic waste processing, in particular to a waste plastic bottle recycling device. Background Art

[0002] Plastic bottles are widely used as containers frequently used in daily life and industrial production. Discarded plastic bottles used in life and scrapped plastic bottles in the production process can be reused after being crushed and recycled through waste plastic bottle recycling equipment.

[0003] During the use of the existing waste plastic bottle recycling equipment, the motor of the waste plastic bottle recycling equipment is first started to drive the crushing rod to rotate at high speed, and then the collected waste plastic bottles are directly put into the waste plastic bottle recycling equipment. Under the strong impact and friction of the crushing rod, the plastic bottles are continuously squeezed, cut and gradually broken. After a period of crushing, the originally complete waste plastic bottles become block-shaped waste plastic pieces. These waste plastic pieces will flow out through the discharge port at the bottom of the equipment. By placing a collection container at the discharge port, these waste plastic pieces can be collected for subsequent cleaning, sorting, melting and recycling.

[0004] However, the existing waste plastic bottle recycling equipment has exposed many problems during actual use. When the plastic bottle is put into the equipment, its bottle body is in an arc shape. During the crushing process, this feature leads to uneven force. The arc bottle body makes it impossible to evenly distribute the force applied by the crushing rod on the entire bottle body. During the crushing process, some areas will bear excessive crushing force and quickly break into small pieces under the strong impact; while other areas will only have slight cracks due to insufficient force, or even remain relatively intact; this uneven crushing situation causes the crushed waste plastic pieces to be of different sizes and irregular shapes, which greatly increases the difficulty of subsequent sorting and cleaning processes. The staff needs to spend more time and energy to deal with these messy waste plastic pieces, resulting in reduced recycling efficiency.

[0005] To this end, the present invention provides a waste plastic bottle recycling device. Summary of the Invention

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Figures 1 to 8 As shown, a waste plastic bottle recycling device described in an embodiment of the present invention includes a body, a fixed frame is fixedly connected to the top of the body, two feed ports are provided on the upper surface of the fixed frame, and a discharge port is provided on the bottom surface of the body, a fixed motor is fixedly connected to the ground of the body, and the output end of the fixed motor is fixedly connected to a fixed shaft, and a plurality of staggered crushing rods are fixedly connected to the circumferential surface of the fixed shaft, and two groups of extrusion assemblies are provided in the fixed frame, each group of extrusion assemblies corresponds to a feed port, and the extrusion assembly includes a push plate slidably arranged in the fixed frame, and the push plate is used to squeeze the waste plastic bottles; a top foot assembly is provided at one end of the push plate, and the top foot assembly includes a connecting frame slidably arranged inside the push plate, and a fixed column is fixedly connected to the surface of the connecting frame, and a torsion spring is sleeved on the circumferential surface of the fixed column, and both ends of the torsion spring are fixedly connected to the same top plate, and the top plate is inside the push plate, and the initial state of the torsion spring is a torque accumulation state.

[0025] Specifically, some waste plastic bottle recycling equipment has exposed many problems during actual use. When the plastic bottle is put into the equipment, due to its arc-shaped bottle body, this feature leads to uneven force in the crushing process. The arc-shaped bottle body makes it impossible to evenly distribute the force applied by the crushing rod on the entire bottle body. During the crushing process, some areas will bear excessive crushing force and quickly break into small pieces under the strong impact; while other areas will only have slight cracks due to insufficient force, or even remain relatively intact. This uneven crushing situation causes the crushed waste plastic pieces to be of different sizes and irregular shapes, greatly increasing the difficulty of subsequent sorting and cleaning processes. Workers need to spend more time and energy to deal with these messy waste plastic pieces, resulting in reduced recycling efficiency. Therefore, the present invention designs the above structure to solve the above problem. First, waste plastic bottles are put into the feed port on the upper surface of the fixed frame, and the fixed motor is started. Its output end drives the fixed shaft to rotate, and then the crushing rod on the fixed shaft rotates accordingly. At the same time, the extrusion assembly starts to operate, and the push plate slides in the fixed frame to squeeze the incoming waste plastic bottles, so that they are squeezed into a flat shape, which is convenient for subsequent crushing processing. When the push plate is pushed to a certain extent, the top foot assembly plays a role, and the connecting frame sliding inside the push plate drives the fixed column to move. At this time, the top plate will rotate under the action of the torsion spring (the torsion spring is initially in a state of torsion accumulation), further applying force to the bottom of the waste plastic bottle to assist in squeezing, squeezing the bottom of the waste plastic bottle close to the bottle body, imitating the process of people squeezing the plastic bottle by hand, first pinching the bottle body, and then pressing the bottom of the bottle towards the bottle body, thereby completing the squeezing of the bottle, and then sending it into the body, contacting with the rotating crushing rod, and further crushed by the displaced crushing rod, and finally the crushed plastic is discharged from the discharge port on the bottom surface of the body. The synergistic effect of the extrusion component and the crushing rod greatly improves the recycling efficiency of waste plastic bottles. The extrusion component first performs a preliminary extrusion on the plastic bottles to make them flat. The surface area of ​​the flattened plastic bottles increases, and the contact with the crushing rod is more complete during crushing, which can reduce the crushing time and reduce energy consumption, making it easier for the subsequent crushing rod to crush them more efficiently. The top foot component uses the torsion force of the torsion spring to accumulate momentum, and provides additional assistance to the extrusion process to squeeze the bottom of the bottle when the push plate advances, thereby enhancing the extrusion effect. The overall equipment has a compact structure and is easy to operate. It can effectively convert waste plastic bottles into reusable fragments, realize resource recycling, and reduce environmental pollution.

[0026] like Figure 4 As shown, the extrusion assembly of this embodiment includes a connecting motor fixedly connected to the upper surface of the fixed frame, a connecting cavity is opened in the fixed frame, the output end of the connecting motor is fixedly connected to the first bevel gear, auxiliary bevel gears are engaged on both sides of the first bevel gear, a reciprocating screw is fixedly connected to one side of the auxiliary bevel gear, one end of the reciprocating screw is rotatably connected to a limiting plate, the limiting plate is fixed to the bottom wall of the connecting cavity, the circumferential surface of the reciprocating screw is slidably connected to the limiting block, and the limiting block is fixed to the push plate.

[0027] Specifically, when the equipment is started to recycle and process waste plastic bottles, the connecting motor starts working, and its output end drives the first bevel gear to rotate. Since auxiliary bevel gears are engaged with both sides of the first bevel gear, the rotation of the first bevel gear will simultaneously drive the two auxiliary bevel gears to rotate synchronously, and the auxiliary bevel gear drives the reciprocating screw fixed to it to rotate. One end of the reciprocating screw is rotatably connected to the limit plate, and the limit plate is fixed to the bottom wall of the connecting cavity to play a stable support role. During the rotation of the reciprocating screw, the limit block slidably connected to its circumferential surface will perform reciprocating linear motion along the reciprocating screw. Because the limit block is fixedly connected to the push plate, the reciprocating motion of the limit block will drive the push plate to slide back and forth in the fixed frame, thereby realizing the squeezing and resetting action of the push plate on the waste plastic bottles, thereby assisting the subsequent crushing process; A connected motor drives the two reciprocating screws to move synchronously, allowing the two push plates to work together, improving the extrusion efficiency and stability. The cooperation between the reciprocating screw and the limit block can accurately control the movement trajectory and speed of the push plates, ensuring the accuracy and reliability of the extrusion action. At the same time, this structure is simple and compact, easy to install and maintain, can effectively reduce equipment costs and failure rates, and improve the overall performance of waste plastic bottle recycling equipment.

[0028] like Figure 4 As shown, in this embodiment, a limiting groove is provided on the lower surface of the limiting block, and a limiting rod is fixedly connected to the bottom wall of the cavity. When the limiting block slides along the reciprocating screw, the limiting plate slides on the surface of the limiting block through the limiting groove.

[0029] Specifically, during the operation of the extrusion assembly, the reciprocating screw rotates to cause the limit block to perform reciprocating linear motion along it. At this time, as the limit block moves, the limit rod slides in the limit groove, guiding the limit block, ensuring that the limit block always slides stably along the axial direction of the reciprocating screw, thereby driving the push plate to accurately perform reciprocating extrusion movements, which can effectively prevent the limit block from deflecting or shaking during movement, ensure the linearity and stability of the push plate movement, improve the accuracy of the extrusion operation, reduce equipment wear and failures caused by motion deviation, extend the service life of the equipment, and at the same time improve the quality and efficiency of waste plastic bottle recycling.

[0030] like Figure 4 As shown, one side of the push plate of this embodiment is slidably connected to an auxiliary block, the upper surface of the auxiliary block is provided with a rotating groove, a rotating arc plate is rotatably connected in the rotating groove, the rotating arc plate is used to limit the waste plastic bottles, and the cross-section of the auxiliary block is concave arc-shaped.

[0031] Specifically, when the push plate drives the auxiliary block to approach, the rotating arc plate in the rotating groove first approaches the bottle body to perform longitudinal limiting work on the waste plastic bottle. Then, during the extrusion process, the rotating arc plate rotates a certain amount to adapt to the extrusion work and improve the extrusion efficiency.

[0032] like Figure 4As shown, a blocking plate is fixed to the lower surface of the auxiliary block of this embodiment, a connecting groove is provided at the position of the blocking plate corresponding to the fixed frame, a drop groove is provided on the surface of the blocking plate, and a number of balls are rotatably connected to both sides of the inner wall of the drop groove, a fixed tube is fixed to one side of the blocking plate, a storage box is fixed to one side of the fixed frame, lubricating oil is stored in the storage box, a connecting tube is fixed to one side of the storage box, and the fixed tube and the connecting tube are slidably connected.

[0033] Specifically, the lubricating oil in the storage box flows along the connecting pipe to the fixed pipe, and then flows into the inside of the sealing plate to lubricate and coat the balls on both sides of the inner wall of the drop chute, so that a certain amount of lubricating oil adheres to the surface of the balls. When the auxiliary block squeezes the waste plastic bottles, it pushes the sealing block to make the drop chute slide out of the fixed frame along the connecting groove, so that the squeezed plastic bottles cannot fall, and the squeezing work is carried out. When the auxiliary block retreats under the action of the push plate, the drop chute is reset, so that the squeezed plastic bottles fall along the drop chute into the body for crushing. By lubricating the balls, the friction between the balls and the waste plastic bottles can be reduced, wear can be reduced, the service life of the balls and related components can be extended, and the waste plastic bottles can be ensured to fall smoothly. The cooperation between the blocking block and the drop chute can prevent the plastic bottles from falling during extrusion, ensuring sufficient extrusion and improving the extrusion effect. After the extrusion is completed, the drop chute is reset to allow the plastic bottles to fall, making the entire recycling process orderly and efficient, and improving the overall operating stability and efficiency of the equipment.

[0034] Example 2: Figures 1 to 8 As shown, compared with Example 1, another embodiment of the present invention is: the top foot assembly includes two groups of springs fixed to one side of the push plate, one end of each group of springs is fixed to a positioning plate, one side of one positioning plate is fixed to a slide plate, one end of the slide plate is fixed to the auxiliary block, and one side of the other positioning plate is fixed to a rack plate, the rack plate is engaged with a fixed gear, the fixed gear is rotatably set in a slide groove opened on the surface of the push plate, the bottom surface of the slide groove is rotatably connected to a rotating shaft, the lower surface of the fixed gear is fixed with an auxiliary gear, the auxiliary gear is engaged with an auxiliary tooth plate perpendicular to the rack plate, and the auxiliary tooth plate is fixed to the connecting frame.

[0035] Specifically, when the push plate drives the auxiliary block to squeeze the waste plastic bottle, the auxiliary block will gradually slide toward one side of the push plate, and the sliding of the push plate drives the rack plate to slide, and the sliding of the rack plate drives the fixed gear to rotate, thereby causing the fixed gear to drive the auxiliary gear to rotate, and the rotation of the auxiliary gear drives the auxiliary gear plate to drive the connecting frame to slide out of the push plate. During the sliding out process of the connecting frame, the top plate rotates under the action of the torsion force of the torsion spring, and during the rotation process, it is folded and squeezed with the flat bottom of the waste plastic bottle, forming an action of holding the flat bottom by hand and pressing it toward the plastic bottle body; When the push plate drives the auxiliary block to squeeze the waste plastic bottles, the top plate produces an action similar to that of a human hand holding the bottom of the bottle and pressing it towards the bottle body. This simulated manual squeezing method can more fully shape and squeeze the waste plastic bottles, making the plastic bottles easier to break in subsequent crushing processing, thereby improving the crushing efficiency and quality. At the same time, no additional human intervention is required, which improves the degree of automation of the equipment and reduces labor costs. Moreover, the entire linkage process is accurate and stable, which can effectively ensure the consistency of each squeezing action and avoid unstable squeezing effects caused by differences in manual operations, further optimizing the waste plastic bottle recycling process and improving the overall recycling efficiency.

[0036] Working principle: first, put the waste plastic bottles into the feed port on the upper surface of the fixed frame, start the fixed motor, and its output end drives the fixed shaft to rotate, thereby causing the crushing rod on the fixed shaft to rotate, and at the same time the connecting motor starts working, and its output end drives the first bevel gear to rotate. Since the auxiliary bevel gears are engaged with both sides of the first bevel gear, the rotation of the first bevel gear will simultaneously drive the two auxiliary bevel gears to rotate synchronously, and the auxiliary bevel gear drives the reciprocating screw fixed to it to rotate. One end of the reciprocating screw is rotated and connected to the limit plate, and the limit plate is fixed to the bottom wall of the connecting cavity to play a stable support role. During the rotation of the reciprocating screw, the limit block slidably connected to its circumferential surface will make reciprocating linear motion along the reciprocating screw. Because the limit block is fixedly connected to the push plate, the reciprocating motion of the limit block will drive the push plate to slide back and forth in the fixed frame, thereby realizing the squeezing and resetting action of the push plate on the waste plastic bottles, so that they are squeezed into a flat shape, which is convenient for subsequent crushing processing; When the push plate is pushed to a certain extent, the top foot assembly plays a role, and the push plate drives the auxiliary block to squeeze the waste plastic bottle. In the process, the auxiliary block will gradually slide toward one side of the push plate, and the sliding of the push plate drives the rack plate to slide. The sliding of the rack plate drives the fixed gear to rotate, and then the fixed gear drives the auxiliary gear to rotate. The rotation of the auxiliary gear drives the auxiliary gear plate to drive the connecting frame to slide out of the push plate. In the process of the connecting frame sliding out, the top plate will rotate under the action of the torsion spring (the torsion spring is initially in a torsion storage state), further applying force to the bottom of the waste plastic bottle to assist in squeezing, squeezing the bottom of the waste plastic bottle close to the bottle body, imitating the process of people squeezing the plastic bottle by hand, first pinching the bottle body, and then pressing the bottom of the bottle toward the bottle body, thereby completing the squeezing of the bottle, and then sending it into the body, contacting the rotating crushing rod, and being further crushed by the displaced crushing rod, and finally the crushed plastic is discharged from the discharge port on the bottom of the body; The synergistic effect of the extrusion component and the crushing rod greatly improves the recycling efficiency of waste plastic bottles. The extrusion component first performs a preliminary extrusion on the plastic bottles to make them flat. The surface area of ​​the flattened plastic bottles increases, and the contact with the crushing rod is more complete during crushing, which can reduce the crushing time and reduce energy consumption, making it easier for the subsequent crushing rod to crush them more efficiently. The top foot component uses the torsion force of the torsion spring to accumulate momentum, and provides additional assistance to the extrusion process to squeeze the bottom of the bottle when the push plate advances, thereby enhancing the extrusion effect. The overall equipment has a compact structure and is easy to operate. It can effectively convert waste plastic bottles into reusable fragments, realize resource recycling, and reduce environmental pollution.

[0037] This artificial extrusion method can more fully shape and squeeze the waste plastic bottles, making them easier to break during subsequent crushing, thereby improving the crushing efficiency and quality. At the same time, it does not require additional human intervention, thereby improving the degree of equipment automation and reducing labor costs. Moreover, the entire linkage process is precise and stable, which can effectively ensure the consistency of each extrusion action and avoid unstable extrusion effects caused by differences in manual operations, further optimizing the waste plastic bottle recycling process and improving the overall recycling efficiency.

During the squeezing process of the waste plastic bottles by the auxiliary block (214), the blocking block is pushed to make the drop groove (218) slide out of the fixed frame (2) along the connecting groove (230), thereby preventing the squeezed plastic bottles from falling and performing the squeezing work. When the auxiliary block (214) is withdrawn under the action of the push plate (213), the drop groove (218) is reset, so that the squeezed plastic bottles fall along the drop groove (218) into the interior of the machine body (1) and are crushed.

9. The waste plastic bottle recycling equipment according to claim 1, characterized in that: The top foot assembly includes two groups of springs (211) fixed to one side of the push plate (213), one end of each group of springs (211) is fixed to a positioning plate (210), one side of one of the positioning plates (210) is fixed to a slide plate (212), one end of the slide plate (212) is fixed to an auxiliary block (214), and one side of the other positioning plate (210) is fixed to a rack plate (220), and the rack plate (220) is meshed with a fixed gear. (222), the fixed gear (222) is rotatably set in a slide groove (229) opened on the surface of the push plate (213), the bottom surface of the slide groove (229) is rotatably connected to the rotating shaft (221), the lower surface of the fixed gear (222) is fixed with an auxiliary gear (223), the auxiliary gear (223) is engaged with an auxiliary tooth plate (224) perpendicular to the rack plate (220), and the auxiliary tooth plate (224) is fixed with the connecting frame (225).

10. The waste plastic bottle recycling equipment according to claim 9, characterized in that: When the push plate (213) drives the auxiliary block (214) to squeeze the waste plastic bottle, the auxiliary block (214) will gradually slide toward one side of the push plate (213), and the sliding of the push plate (213) drives the rack plate (220) to slide. The sliding of the rack plate (220) drives the fixed gear (222) to rotate, thereby causing the fixed gear (222) to drive the auxiliary gear (223) to rotate. The rotation of the auxiliary gear (223) drives the auxiliary gear plate (224) to drive the connecting frame (225) to slide out of the push plate (213). When the connecting frame (225) slides out, the top plate (228) rotates under the action of the torsion of the torsion spring (227). During the rotation, the top plate (228) is folded and squeezed with the flat bottom of the waste plastic bottle, forming an action of a person holding the flat bottom and pressing it toward the plastic bottle body.
