Description

Technical Field

[0001] This utility model relates to the field of plastic extrusion technology, and in particular to an extrusion mechanism for processing plastic bottles. Background Technology

[0002] Plastic bottles (such as PET bottles and HDPE bottles) are widely used in beverage, food, daily chemical, and pharmaceutical industries due to their lightweight, impact resistance, and ease of processing. With the development of the plastic recycling industry, the recycling of waste plastic bottles has become an important direction for environmental protection and resource recycling. After crushing and cleaning, waste plastic bottles can be processed into recycled plastic granules or products through an extrusion mechanism, thereby realizing waste utilization.

[0003] Currently, traditional plastic bottle processing extrusion mechanisms typically involve feeding raw materials into a screw conveyor, melting the materials, and then processing them into recycled plastic granules or products through an extrusion mechanism. This method has drawbacks: when the feeding speed increases, a "bridging" phenomenon occurs at the feeding port, resulting in unstable material supply to the extruder and defects such as "material shortage" and "broken strips" in the products. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a plastic bottle processing extrusion mechanism, which aims to improve the problem of easy blockage of the discharge port when the feeding speed is too fast in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An extrusion mechanism for processing plastic bottles includes a support platform, a screw conveyor fixedly connected to the top of the support platform, a second motor arranged on the right side of the support platform, the output end of the second motor fixedly connected to the right side of the screw conveyor, an extruder fixedly connected to the left side of the screw conveyor, multiple electric heating plates fixedly connected to the top left side of the screw conveyor, a feeding hopper fixedly connected to the top right side of the screw conveyor, and a vibration component and a purification component arranged sequentially from right to left on the top of the support platform.

[0007] The vibration assembly includes a motor, the bottom of which is fixedly connected to the top of the support platform. A cam is fixedly connected to the output end of the motor. A bracket is fixedly connected to the right side of the top of the support platform. A baffle is slidably connected inside the bracket. A push rod is fixedly connected to the middle of the baffle. A spring is sleeved on the outer periphery of the push rod. The spring is located inside the bracket.

[0008] As a further description of the above technical solution:

[0009] The purification component includes an exhaust pipe, the bottom of which is fixedly connected to the top of the auger conveyor. A connecting pipe is fixedly connected to the middle of the exhaust pipe, and a purification box is fixedly connected to the end of the connecting pipe away from the exhaust pipe. A purification plate is slidably connected inside the purification box, and multiple activated carbons are placed inside the purification plate.

[0010] As a further description of the above technical solution:

[0011] One end of the spring is fixedly connected to the side of the baffle away from the cam, and the other end of the spring is fixedly connected to the inner wall of the bracket.

[0012] As a further description of the above technical solution:

[0013] The push rod passes through and is slidably connected inside the bracket. A rubber pad is fixedly connected to the end of the push rod away from the cam, and the rubber pad abuts against the feeding funnel.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the purification box is fixedly connected to two slide rails, and the purification plate is slidably connected between the two slide rails;

[0016] As a further description of the above technical solution:

[0017] Magnet 1 is fixedly connected inside each of the two slide rails, and two magnet 2 are fixedly connected inside the purification plate. Magnet 1 and magnet 2 are magnetically attracted to each other.

[0018] As a further description of the above technical solution:

[0019] The bracket has a groove inside, the baffle is slidably connected to the inner wall of the groove, and the push rod is slidably connected inside the groove;

[0020] As a further description of the above technical solution:

[0021] A handle is fixedly connected to the outside of the purification panel, and an exhaust pipe is fixedly connected to the top of the purification box.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a motor is set up to drive the cam to rotate. When the cam rotates, it squeezes the push rod. The movement of the push rod will drive the baffle to move, thereby squeezing the spring. When the cam does not squeeze the push rod, the squeezed spring will push the baffle to move in the opposite direction, thereby resetting the push rod. Therefore, by repeatedly rotating the cam, the push rod makes reciprocating motion. By repeatedly touching the feeding funnel, the feeding funnel vibrates, thereby preventing the "bridging phenomenon" at the feeding funnel and avoiding the accumulation of raw materials at the feeding funnel, which significantly improves the feeding efficiency and stability.

[0024] 2. In this utility model, when the raw material is in the auger conveyor, the electric heating plate is activated to melt it. The waste gas released when the plastic bottle is subjected to high temperature enters the connecting pipe through exhaust pipe one and is then transported to the purification box. During the process of the gas rising in the purification box, the odor is adsorbed by the activated carbon in the purification plate to complete the purification. Finally, it is discharged through exhaust pipe two, which effectively avoids air pollution and ensures the health of the staff. Moreover, the purification plate can be quickly replaced by pulling the handle. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a plastic bottle processing extrusion mechanism, including a support platform 1. A screw conveyor 19 is fixedly connected to the top of the support platform 1. The screw conveyor 19 is used to transport raw materials. A second motor 12 is arranged on the right side of the support platform 1. The output end of the second motor 12 is fixedly connected to the right side of the screw conveyor 19. By starting the second motor 12, the screw conveyor 19 starts to work. An extruder 2 is fixedly connected to the left side of the screw conveyor 19. The extruder 2 is used to extrude the plastic after high temperature melting into shape. Multiple electric heating plates 4 are fixedly connected to the top left side of the screw conveyor 19. The electric heating plates 4 are used to heat the transported raw materials. A feeding hopper 3 is fixedly connected to the top right side of the screw conveyor 19. The raw materials are transported into the screw conveyor 19 through the feeding hopper 3. A vibration component and a purification component are arranged sequentially from right to left on the top of the support platform 1. The vibration component is used to prevent the feeding hopper 3 from being blocked. The purification component is used to purify the waste gas generated when the plastic is melted.

[0034] The vibration assembly includes a motor 6, the bottom of which is fixedly connected to the top of the support platform 1. A cam 5 is fixedly connected to the output end of the motor 6. A bracket 11 is fixedly connected to the top right side of the support platform 1. A baffle 15 is slidably connected inside the bracket 11. A push rod 17 is fixedly connected to the middle of the baffle 15. A spring 16 is sleeved around the outer periphery of the push rod 17 and is located inside the bracket 11. The motor 6 drives the cam 5 to rotate. During rotation, the protruding part of the cam 5 presses against the push rod 17. Because the push rod 17 is equipped with the baffle 15 and spring 16, when the push rod 17 moves and causes the baffle 15 to press against the spring 16, the spring 16 pushes the baffle 15 in the opposite direction, thus resetting the push rod 17. The cam 5 repeatedly touches the push rod 17, causing the push rod 17 to reciprocate. The push rod 17 then repeatedly touches the feeding hopper 3, thereby accelerating the feeding process and preventing bridging.

[0035] Reference Figure 1 , Figure 2 and Figure 4The purification component includes an exhaust pipe 7, the bottom of which is fixedly connected to the top of the auger conveyor 19. A connecting pipe 8 is fixedly connected to the middle of the exhaust pipe 7. A purification box 10 is fixedly connected to the end of the connecting pipe 8 away from the exhaust pipe 7. A purification plate 14 is slidably connected inside the purification box 10. Multiple activated carbons 20 are placed inside the purification plate 14. The exhaust gas generated when the plastic is melted will be transported to the purification box 10 through the exhaust pipe 7 and the connecting pipe 8, and then drift to the purification plate 14. The activated carbon 20 in the purification plate 14 will adsorb the odor, thereby purifying the exhaust gas. Then it will be discharged into the air through the exhaust pipe 9.

[0036] Reference Figure 3 One end of the spring 16 is fixedly connected to the side of the baffle 15 away from the cam 5, and the other end of the spring 16 is fixedly connected to the inner wall of the bracket 11. When the baffle 15 compresses the spring 16, the spring 16 will generate a force to restore its original shape, thereby pushing the baffle 15 to move in the opposite direction.

[0037] Reference Figure 1 and Figure 3 The push rod 17 passes through and is slidably connected inside the bracket 11. A rubber pad 18 is fixedly connected to the end of the push rod 17 away from the cam 5. The rubber pad 18 abuts against the feeding funnel 3. When the cam 5 repeatedly squeezes the push rod 17, the rubber pad 18 on the push rod 17 will repeatedly touch the feeding funnel 3, thereby causing the feeding funnel 3 to vibrate, thus preventing the feeding funnel 3 from getting blocked and avoiding slow feeding. In addition, the rubber pad 18 fits snugly with the feeding funnel 3, reducing damage to the feeding funnel 3.

[0038] Reference Figure 4 and Figure 5 Two slide rails 23 are fixedly connected to the inner wall of the purification box 10. The purification plate 14 is slidably connected between the two slide rails 23. When the purification plate 14 needs to be replaced, pull the purification plate 14 to slide between the two slide rails 23 and then detach it from the purification box 10.

[0039] Reference Figure 5 Magnet 1 21 is fixedly connected inside each of the two slide rails 23, and two magnets 22 are fixedly connected inside the purification plate 14. Magnet 1 21 and magnet 22 are magnetically attracted to each other. The side of magnet 1 21 facing outward is set as the N pole, and the side of magnet 22 facing outward is set as the S pole. By using the principle of "opposites attract", the purification plate 14 will not slide randomly when it is absorbing odors.

[0040] Reference Figure 3 The bracket 11 has a groove 24 inside, the baffle 15 is slidably connected to the inner wall of the groove 24, and the push rod 17 is slidably connected inside the groove 24. When the push rod 17 moves, it will drive the baffle 15 to slide on the inner wall of the groove 24.

[0041] Reference Figure 1and Figure 2 A handle 13 is fixedly connected to the outside of the purification plate 14. Pulling the handle 13 allows the purification plate 14 to be quickly removed. An exhaust pipe 2 9 is fixedly connected to the top of the purification box 10. The purified gas will be discharged into the air through the exhaust pipe 2 9 to avoid air pollution.

[0042] Working Principle: Raw materials are poured into the auger conveyor 19 from the feeding hopper 3. When the feeding speed increases, a "bridging" phenomenon easily occurs inside the feeding hopper 3. At this time, motor 6 needs to be started. Motor 6 drives cam 5 to rotate. When cam 5 rotates, the protruding part of its edge will intermittently touch push rod 17, causing push rod 17 to move laterally. Since baffle 15 and spring 16 are set on the outer periphery of push rod 17, when push rod 17 moves, it will drive baffle 15 to move, thereby squeezing spring 16. The spring 16 is squeezed and generates a reaction force, which will act on baffle 15, thereby causing baffle 15 to drive push rod 17 to move. Then, when the protruding part of cam 5 slides away from push rod 17, spring 16 will push baffle 15 to move, and then push rod 17 will return to its original position, thus completing one contact action. Through the continuous rotation of cam 5, push rod 17 will reciprocate, thereby causing the feeding hopper 3 to vibrate and accelerate feeding.

[0043] When the raw material is in the auger conveyor 19, the electric heating plate 4 is activated to melt it. When the plastic bottle is exposed to high temperature, some waste gas will be released. This gas will enter the connecting pipe 8 through the exhaust pipe 7, and then be transported to the purification box 10 through the connecting pipe 8. When the gas enters the purification box 10, it will slowly float upward and pass through the purification plate 14. The activated carbon 20 in the purification plate 14 will absorb the odor in the gas, thereby purifying the gas. Then it will be discharged into the air through the exhaust pipe 9, thus preventing the generated gas from polluting the air. When the purification plate 14 needs to be replaced, it can be quickly replaced by pulling the handle 13.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
