Description

Technical Field

[0001] The present invention belongs to the technical field of plastic recycling, and in particular relates to a plasticizer for recycling crushed plastics. Background Art

[0002] The working principle of the plasticizer mainly involves physical and chemical processes, including heating, shearing, mixing and pressure application. The structure of the plasticizer usually includes a motor, a reducer, a shaft, a heating ring and a container. The motor provides power, which is transmitted to the shaft through the reducer. The heating ring on the shaft provides heat to heat the plastic evenly and melt it. The rotation of the shaft also plays a mixing role, so that the various parts of the plastic are fully mixed to achieve the plasticizing effect. Mechanical plasticization is a process that softens thermoplastics and makes them plastic with the help of mechanical equipment. This process is mainly carried out in a roller plasticizer or a closed mixer. The mechanical shear force and heat action are used to break the molecular chains and improve the plasticity of the material.

[0003] In order to achieve better plasticization, plastics need to be crushed before recycling and plasticization, and the plastic debris needs to be transported to the plasticizer for plasticization. For large-volume plastics, it is easy to get blocked at the entrance of the plasticizer. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a crushed plastic recycling plasticizer, which can crush the plastic waste before recycling and plasticizing it, and transport it to the plasticizer for recycling and plasticizing.

[0005] The purpose of this disclosure can be achieved through the following technical solutions:

[0006] A plasticizer for recycling crushed plastics, comprising:

[0007] A crushing box, wherein two cross bars are fixedly connected up and down inside the crushing box, a rotating shaft is rotatably connected to the cross bar, a rotating blade and a first bevel gear are fixedly connected to the rotating shaft, two first bevel gears are respectively arranged at one end close to the two rotating shafts, a second bevel gear is meshedly connected between the two first bevel gears, a transmission shaft is fixedly connected to the side of the second bevel gear, and the transmission shaft passes through the crushing box and is rotatably connected to the side wall of the crushing box;

[0008] A collecting bucket, the collecting bucket is fixedly connected to the lower end of the crushing box, the two sides of the collecting bucket are rotatably connected with connecting rods, and two connecting rods are arranged on each side, the two ends of the connecting rods are fixedly connected with sprockets, the upper and lower sprockets on the same side are meshed with chains, and a plurality of scrapers are fixedly connected between the two chains on the same side;

[0009] A delivery pipe, the delivery pipe is fixedly connected to the lower end of the collecting bucket, and an auger is rotatably connected inside the delivery pipe;

[0010] A plasticizing machine body, wherein the feeding end of the plasticizing machine body is fixedly connected to the discharging end of the conveying pipe.

[0011] The above technical solution, its principle and technical effect:

[0012] When the plastic waste is put into the crushing box, the transmission shaft rotates to drive the second bevel gear to rotate, and the second bevel gear drives the two first bevel gears to rotate in the opposite direction, so that the two rotating blades rotate in the opposite direction to crush the plastic waste, and the crushing effect is better. The crushed debris enters the collection bucket, and the auger rotates to transport the debris to the plasticizer body for plasticization. Among them, the driving connecting rod rotates to drive the chain transmission. On the one hand, the scraper can scrape off the debris attached to the side wall of the collection bucket, and on the other hand, it disturbs the debris to prevent the debris from squeezing each other at the bottom of the collection bucket and failing to fall into the conveying pipe.

[0013] Furthermore, a feed port is provided at the upper end of the crushing box, and a feed hopper is fixedly connected to the peripheral side of the feed port.

[0014] Furthermore, the other end of the transmission shaft is fixedly connected to the output end of the first motor.

[0015] Furthermore, a first fixed platform is fixedly connected to the side of the collecting bucket, and the first motor is fixedly connected to the first fixed platform.

[0016] Furthermore, the outer ends of the connecting rods on both sides of the lower end of the collecting bucket are fixedly connected to the first gear, the outer ends of the auger are fixedly connected to the second gear, and the two first gears are meshed and connected with the second gear.

[0017] Furthermore, the outer end of the auger is fixedly connected to the output end of the second motor.

[0018] Furthermore, a leg is fixedly connected to the lower end of the conveying pipe, a second fixed platform is fixedly connected to the side of the leg, and the second motor is fixedly connected to the second fixed platform.

[0019] Furthermore, the diameter of the collecting bucket decreases from top to bottom.

[0020] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0021] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0022] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0023] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0024] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0025] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0026] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0027] Beneficial effects of the present disclosure:

[0028] Before the plastic waste is recycled and plasticized, the plastic waste can be crushed and transported to the plasticizer for recycling and plasticization. BRIEF DESCRIPTION OF THE DRAWINGS
