Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to a PP production device for plastic products. Background Technique

[0002] PP plastic refers to polypropylene plastic, which is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resists corrosion by a variety of organic solvents and acids and alkalis. It has a wide range of applications in the industrial field and is one of the common polymer materials.

[0003] In the related technology, the Chinese patent document with the application number CN210116079U proposed a crushing device for plastic product production. When in use, the feeding pipe is connected to the feeding pipeline, and the discharging pipe is connected to the collecting device. Plastic particles enter the inside of the rotating cylinder through the feeding pipe. The rotating motor drives the transmission shaft to rotate through the first transmission belt, so that the rotating cylinder rotates, driving the entering plastic particles to turn up and down under the action of centrifugal force and gravity. The crushing motor drives the connecting cylinder to rotate through the second transmission belt, driving the cutting blades to cut the plastic particles inside the rotating cylinder. At the same time, under the action of centrifugal force, the cut smaller particles enter the inside of the outer shell through the fine holes outside the rotating cylinder and are discharged through the discharging pipe through the internal shape characteristics. When cutting, the fan starts to send air into the inside of the ventilation pipe, and sprays and sweeps the rotating cylinder through the air jet head at the bottom of the ventilation pipe to prevent larger particles from blocking the fine holes and making them re-enter the inside of the rotating cylinder for crushing. At the same time, the sprayed air flow drives the crushed plastic particles inside the outer shell into the discharging pipe after flowing inside.

[0004] In view of the above related technology, the inventor believes that there are the following defects: However, the above patent does not have a drying device for plastic particles. In the existing drying device, plastic particles often pile up together during drying, making it difficult for the plastic particles to come into full contact with the hot air for drying. The plastic particles may be unevenly dried, and it is also possible to reduce the drying efficiency of the plastic particles. In view of this, a PP production device for plastic products is proposed to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a PP production device for plastic products, which solves the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A PP production device for plastic products, including a drying box, a feeding pipe is fixed at the upper end of the drying box, a drying mechanism is arranged inside the drying box, and a dispersion mechanism is arranged inside the drying box;

[0007] The dispersion mechanism includes a guiding plate and a first rotating shaft. Two guiding plates are horizontally arranged in the drying box. A second discharge port is formed on one side of each of the two guiding plates. A fixing frame is fixed to the outside of the guiding plate. A rack is fixed to one side of the fixing frame. A rotatable first rotating shaft is vertically arranged in the drying box. A transmission gear meshing with the rack is fixed to the first rotating shaft.

[0008] Blocks are fixed to both sides of the fixing frame. A spring is fixed to the baffle. One end of the spring is fixed to the inner wall of the drying box. Through holes are formed on both sides of the fixing frame. A limiting rod slidably connected to the through holes is fixed in the drying box.

[0009] Furthermore, the two guiding plates are distributed vertically, and the length of the lower guiding plate is longer than that of the upper guiding plate.

[0010] Furthermore, the second discharge ports on the upper and lower guiding plates are located at the farthest ends away from each other. The guiding plate is lower near the second discharge port and higher away from the second discharge port.

[0011] Furthermore, both the guiding plate and the fixing frame are hollow. One end of the first rotating shaft is driven to rotate by an external motor.

[0012] Furthermore, the dispersion mechanism includes a dispersion cover. The dispersion cover is fixed to the inner top wall of the drying box. A second rotating shaft is horizontally arranged and rotatable in the dispersion cover. A plurality of fan blades are fixed to the outside of the second rotating shaft. One end of the second rotating shaft is fixed with a driven bevel gear. A driving bevel gear meshing with the driven bevel gear is fixed to the first rotating shaft.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-6 , a PP production device for plastic products in this embodiment, includes a drying box 1, and is characterized in that: a feed pipe 2 is fixed at the upper end of the drying box 1, a discharge port is opened at the lower end of the drying for collecting the dried plastic particles, a drying mechanism 3 is arranged in the drying box 1, and a dispersion mechanism 4 is arranged in the drying box 1.

[0025] The dispersion mechanism 4 includes a guiding plate 402 and a first rotating shaft 404. Two guiding plates 402 are horizontally arranged in the drying box 1. Second discharge ports 413 are opened on one side of each of the two guiding plates 402. A fixing frame 401 is fixed outside the guiding plate 402. A rack 417 is fixed on one side of the fixing frame 401. A rotatable first rotating shaft 404 is vertically arranged in the drying box 1. A transmission gear 416 meshing with the rack 417 is fixed on the first rotating shaft 404. There are multiple clips missing on the outside of the transmission gear 416.

[0026] On both sides of the fixed frame 401, stoppers 414 are fixed. A spring 415 is fixed on the baffle. One end of the spring 415 is fixed to the inner wall of the drying box 1. Through holes 411 are provided on both sides of the fixed frame 401. A limiting rod 412 that is slidably connected to the through holes 411 is fixed in the drying box 1. Both the guiding plate 402 and the fixed frame 401 are hollowed out, and the diameter of the hollowing is smaller than the diameter of the plastic particles. One end of the first rotating shaft 404 is driven to rotate by an external motor. A plurality of fixing blocks 403 are fixed in the drying box 1, and circular holes that are rotatably connected to the first rotating shaft 404 are provided in the fixing blocks 403.

[0027] By starting the external motor, the external motor drives the first rotating shaft 404 to rotate, and then the first rotating shaft 404 drives the transmission gear 416 to rotate. Then, the transmission gear 416 meshes with the rack 417, so that the fixed frame 401 and the guiding plate 402 can move. Subsequently, with the assistance of the spring 415, the fixed frame 401 can move back and forth on the limiting rod 412, so that the plastic particles are evenly spread on the guiding plate 402, and then hot air is used to dry them.

[0028] Among them, the two guiding plates 402 are distributed vertically. The length of the lower guiding plate 402 is longer than that of the upper guiding plate 402 to prevent the plastic shells falling from the upper second discharge port 413 from falling outside the lower fixed frame 401.

[0029] At the same time, the second discharge ports 413 on the upper and lower guiding plates 402 are located at the farthest ends away from each other, so that the plastic particles stay on the guiding plate 402 for a longer time. The guiding plate 402 is lower near the second discharge port 413 and higher away from the second discharge port 413, so that the plastic particles can fall from the second discharge port 413 as the guiding plate 402 reciprocates.

[0030] In addition, the dispersion mechanism 4 includes a dispersion cover 408. The dispersion cover 408 is fixed to the inner top wall of the drying box 1. A rotatable second rotating shaft 407 is horizontally arranged in the dispersion cover 408. A plurality of fan blades 410 are fixed to the outside of the second rotating shaft 407. The outside of the fan blades 410 is slidably connected to the inner side wall of the dispersion cover 408. One end of the second rotating shaft 407 is fixed with a driven bevel gear 406, and a driving bevel gear 405 that meshes with the driven bevel gear 406 is fixed on the first rotating shaft 404. A first discharge port 409 is provided on one side of the dispersion cover 408. The dispersion cover 408 is communicated with the feed pipe 2. By the rotation of the first rotating shaft 404, the driving bevel gear 405 is driven to rotate, and then the driving bevel gear 405 meshes to drive the second rotating shaft 407 to rotate. Then, the second rotating shaft 407 drives the fan blades 410 to rotate to quantitatively convey the plastic particles in the dispersion cover 408, and then discharge them from the first discharge port 409.

[0031] Please refer to Figure 1, in this embodiment, the drying mechanism 3 includes a drying box 1 and a blower 305. A heating box 301 is embedded on one side of the drying box 1. A plurality of heating wires 302 are fixed inside the heating box. A plurality of air outlet holes 303 evenly distributed are formed on the side of the heating box 301 facing the inside of the drying box 1. The blower 305 is fixedly installed on the drying box 1, and a connecting pipe 304 is communicated between the output end of the blower 305 and the heating box 301.

[0032] By starting the blower 305 and the heating wires 302, the blower 305 conveys the gas into the heating box 301, and then the heating wires 302 heat the gas, which is discharged through the air outlet holes 303 to dry the plastic particles in the drying box 1.

[0033] The working principle of the above embodiment is as follows:

[0034] The plastic particles are poured from the feed pipe 2 and fall into the dispersion cover 408. Then, by starting the external motor, the external motor drives the first rotating shaft 404 to rotate. Then, due to the rotation of the first rotating shaft 404, the driving bevel gear 405 is driven to rotate. Then, through the meshing of the driving bevel gear 405, the second rotating shaft 407 is driven to rotate. Then, the second rotating shaft 407 drives the fan blade 410 to rotate, quantitatively conveying the plastic particles in the dispersion cover 408, and then discharging them from the first discharge port 409.

[0035] They fall into the upper guiding plate 402. Then, by starting the blower 305 and the heating wires 302, the blower 305 conveys the gas into the heating box 301, and then the heating wires 302 heat the gas, which is discharged through the air outlet holes 303 to dry the plastic particles in the drying box 1.

[0036] Subsequently, the first rotating shaft 404 drives the transmission gear 416 to rotate. Then, the transmission gear 416 meshes with the rack 417, so that the fixed frame 401 and the guiding plate 402 can move. Subsequently, assisted by the spring 415, the fixed frame 401 can move back and forth on the limiting rod 412, so that the plastic particles are evenly spread on the upper guiding plate 402. The gas is discharged through the air outlet holes 303 to dry the plastic particles in the drying box 1. Then, they fall through the second discharge port 413 onto the lower guiding plate 402 for re-drying. Subsequently, the plastic particles are discharged and collected through the lower second discharge port 413.
