Description

Technical Field

[0001] This utility model belongs to the field of plastic recycling technology, and in particular relates to a plastic filler recycling device. Background Technology

[0002] Plastic packing materials were developed based on soft and semi-soft packing materials, combining the advantages of both. Their structure involves replacing the pressed plastic discs with double-ringed large plastic rings, with aldehyde-modified fibers or polyester filaments pressed onto the rings to ensure even fiber distribution. The inner ring consists of snowflake-shaped plastic branches, which can both support biofilm and effectively cut air bubbles, improving oxygen transfer rate and utilization. Currently, in the recycling process of plastic packing materials, fusion and recycling are required. However, this process faces challenges such as the inability to pulverize the raw materials, uneven heating during melting, and low recycling efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a plastic filler recycling device, which effectively solves the problems of uneven heating of raw material melting and low recycling efficiency.

[0004] The technical solution to the technical problem is as follows: It includes a barrel body with an inlet. A crushing device is installed inside the barrel body below the inlet. A limiting plate is fixed inside the barrel body, and a heating wire is installed inside the limiting plate. A support plate is fixed inside the barrel body below the limiting plate. A vertically rotating shaft is rotatably connected to the support plate. Multiple first stirring rods are evenly and coaxially fixed around the circumference of the rotating shaft. First rake teeth are fixed to the lower end of each first stirring rod. A first gear is coaxially fixed to the rotating shaft. Multiple vertically fixed shafts are fixed to the support plate, and these fixed shafts are evenly distributed around the circumference of the rotating shaft. A fixed shaft is rotatably connected to a second gear that meshes with the first gear. An internal gear ring is rotatably connected inside the barrel and meshes with the second gear. A disc is fixed on the upper end face of the internal gear ring. A vertical sleeve is fixed in the middle of the disc. The sleeve is rotatably connected to a limiting plate. The rotating shaft is located inside the sleeve. Multiple second stirring rods are evenly fixed around the circumference of the sleeve. Each second stirring rod has a second rake tooth located below the first rake tooth. The first and second rake teeth are staggered and are both located above the limiting plate. The barrel is provided with a discharge port located above the limiting plate.

[0005] Preferably, the pulverizing device includes a first pulverizing roller and a second pulverizing roller, which rotate in opposite directions.

[0006] Preferably, a power controller is installed on the outside of the barrel, and the controller is electrically connected to the heating wire.

[0007] Preferably, a circular ring is fixed inside the barrel, and the circular ring is rotatably connected to an internal gear ring.

[0008] Preferably, a motor is installed at the bottom of the barrel, and the motor is coaxially and fixedly connected to the rotating shaft.

[0009] This invention has the following advantages over traditional equipment: it has a clever structure and good linkage. By adopting a star-shaped mechanism, it cleverly achieves that the rotation direction of the rotating shaft and the sleeve is opposite. The first rake tooth faces downward and the second rake tooth faces upward. The first and second rake teeth are staggered and distributed vertically, and the rotation direction of the first and second rake teeth is opposite. The novel structure can fully stir the plastic filler above the limiting plate, improve the melting rate of the plastic filler, achieve good recycling effect, and is simple to operate, economical and durable.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 3A plastic filler recycling device is provided, comprising a barrel body 1 with an inlet 2 on the barrel body 1, a crushing device installed below the inlet 2 inside the barrel body 1, a limiting plate 3 fixed inside the barrel body 1, a heating wire 4 installed inside the limiting plate 3, a support plate 5 fixed inside the barrel body 1 below the limiting plate 3, a vertically rotating shaft 6 rotatably connected to the support plate 5, a plurality of first stirring rods 7 evenly fixed around the circumference of the rotating shaft 6, a first rake tooth 8 fixed at the lower end of the first stirring rod 7, a first gear 9 coaxially fixed to the rotating shaft 6, and a plurality of vertically fixed shafts 10 fixed to the support plate 5, the plurality of fixed shafts 10 being evenly distributed around the circumference of the rotating shaft 6, and the fixed shafts 10 being rotatably connected to... A second gear 11 meshes with the first gear 9. An internal gear ring 12 is rotatably connected inside the barrel body 1. The internal gear ring 12 meshes with the second gear 11. A disc 13 is fixed on the upper end face of the internal gear ring 12. A vertical sleeve 14 is fixed in the middle of the disc 13. The sleeve 14 is rotatably connected to the limiting plate 3. The rotating shaft 6 is located inside the sleeve 14. Multiple second stirring rods 15 are evenly fixed around the circumference of the sleeve 14. The second stirring rods 15 are fixed with second rake teeth 16 located below the first rake teeth 8. The first rake teeth 8 and the second rake teeth 16 are staggered. The first rake teeth 8 and the second rake teeth 16 are both located above the limiting plate 3. The barrel body 1 is provided with a discharge port 17 located above the limiting plate 3.

[0016] The crushing device includes a first crushing roller 18 and a second crushing roller 19, which rotate in opposite directions.

[0017] A power controller 20 is installed on the outside of the barrel 1, and the controller is electrically connected to the heating wire 4.

[0018] To ensure the stability of the internal gear ring 12 rotating within the barrel 1, a ring 21 is fixed inside the barrel 1, and the ring 21 is rotatably connected to the internal gear ring 12.

[0019] A motor is installed at the bottom of the barrel body 1, and the motor is coaxially and fixedly connected to the rotating shaft 6.

[0020] In use, the operator inserts the plastic filler into the barrel 1 through the feed inlet 2, starts the crushing device, and the first crushing roller 18 and the second crushing roller 19 rotate in opposite directions. Under the friction of the first crushing roller 18 and the second crushing roller 19, the plastic filler is crushed in the crushing chamber. The crushed plastic filler falls onto the limiting plate 3 under the action of gravity. The power controller 20 is turned on, a suitable temperature is set, and the heating wire 4 is energized to heat the limiting plate 3. At this time, the plastic filler on the limiting plate 3 melts. A bracket is fixed at the bottom of the barrel 1, and a motor is fixedly installed on the bracket. A motor drives a rotating shaft 6 to rotate coaxially. The rotating shaft 6 is located in the middle of the barrel 1. The rotating shaft 6 drives the first gear 9 and the first stirring rod 7 to rotate coaxially. The first stirring rod 7 drives the first rake teeth 8 to rotate together. The first gear 9 drives the second gear 11 to rotate. The second gear 11 meshes with the internal gear ring 12. Since the position of the fixed shaft 10 remains unchanged, the internal gear ring 12 rotates within the ring 21. Therefore, the second gear 11 drives the internal gear ring 12 to rotate. The internal gear ring 12 drives the disc 13 and the sleeve 14 to rotate synchronously. The sleeve 14 drives the second stirring rod 15 to rotate coaxially. The second stirring rod 15 drives the second rake teeth... The first and second rake teeth 16 rotate together. Both the first rake tooth 8 and the second rake tooth 16 are located above the limiting plate 3. The first rake tooth 8 is located below the first stirring rod 7, and the second rake tooth 16 is located above the second stirring rod 15. The first stirring rod 7 is located above the second stirring rod 15. Therefore, the first rake tooth 8 and the second rake tooth 16 are staggered vertically. Furthermore, the rotation directions of the rotating shaft 6 and the sleeve 14 are opposite. Taking clockwise rotation of the rotating shaft 6 as an example, the rotating shaft 6 drives the first rake tooth 8 to rotate clockwise, and the rotating shaft 6 drives the first gear 9 to rotate clockwise. Therefore, the second gear 11 rotates counterclockwise, and the internal gear ring 12 rotates counterclockwise. The internal gear ring 12 drives the sleeve... The first rake tooth 8 and the second rake tooth 16 rotate counterclockwise synchronously, so the rotation directions of the first rake tooth 8 and the second rake tooth 16 are opposite. As a result, the first rake tooth 8 and the second rake tooth 16 can fully stir the plastic filler on the limiting plate 3. The upper and lower rake teeth stir alternately, resulting in good stirring effect, accelerating the melting of the plastic, improving the recycling efficiency of the plastic filler, and having good linkage. It saves time and effort. The melted plastic is discharged through the discharge port 17 to realize the recycling of plastic. In addition, a rotary sealing ring is installed between the sleeve 14 and the rotating shaft 6, and a rotary sealing ring is installed between the limiting plate 3 and the sleeve 14, which plays a good sealing role and prevents the melted plastic from leaking.

[0021] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
