Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing, and particularly relates to a recycled plastic granulator. Background Art

[0002] A plastic granulator is a device mainly used to heat plastic raw materials to a viscous flow state, continuously extrude them through an extrusion die head under pressure, then cool them to form a strip-shaped vitreous state, and finally obtain cylindrical or elliptical plastic particles through a granulating device. This process involves the recycling and reuse of plastics. Through steps such as crushing, cleaning, and granulating, waste plastics are transformed into reusable plastic particles. However, the processed particles are uneven, there are many non-standard plastic particles and it is not easy to remove them. Now, a structure capable of screening plastic particles is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a recycled plastic granulator, which solves the above problems.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A recycled plastic granulator includes a frame, and further includes: a screening component for screening plastic particles; the screening component includes a mesh plate, a baffle plate, and a push rod. The baffle plate is fixedly connected to the mesh plate, the baffle plate is slidably connected to the frame, one end of the push rod is hinged to the baffle plate, and the other end of the push rod is rotatably connected to an eccentric wheel.

[0005] Advantageous Effects

[0006] The utility model provides a recycled plastic granulator, which has the following advantageous effects compared with the prior art:

[0007] Related technicians place the plastic rods cooled by passing water through them into the mesh holes of the frame respectively, start the motor and begin to manually push the plastic rods at the same time. At this time, the motor drives the axle fixedly connected to its output shaft to rotate synchronously. At this time, the bevel gear A fixedly connected to the axle starts to rotate, so that the bevel gear A drives the bevel gear B meshed with it to start rotating, and the bevel gear B drives the shaft fixedly connected to its axis to rotate synchronously, so that the shaft drives the pulley A fixedly connected to it to start rotating, and the pulley B starts to rotate synchronously with the pulley A under the cooperation of the belt drivingly connected to it, so that the connecting rod drives the gear fixedly connected to its top to start rotating, and the gear drives the gear ring meshed with it to start rotating, and the gear ring drives the cutter head fixedly connected to it to rotate synchronously. Thus, when the plastic rods are pushed out from the mesh holes on the frame, the plastic rods can be cut into plastic pellets by the cyclic rotation of the cutter head, and the plastic pellets fall on the mesh plate. At the same time, when the axle rotates, it drives the eccentric wheel fixedly connected to it to rotate synchronously, so that the eccentric wheel drives the push rod rotatably connected to its eccentric part to rotate synchronously, so that the push rod starts to push the baffle hinged to it, and the baffle starts to slide reciprocally along its connection with the frame, so that the plastic pellets on the mesh plate start to roll on it under the action of inertia, avoiding the accumulation of plastic pellets. At the same time, the qualified plastic pellets can fall along the mesh holes on the mesh plate, so as to screen the plastic pellets and avoid the mixing of unqualified plastic pellets among them.

[0020] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific frame 101 recorded in the above embodiment. For example, a receiving box can be placed below the opening. The purpose of this setting is to facilitate receiving plastic particles through this setting.

[0021] Specifically, a shaft 208 is fixedly connected to the center of the bevel gear B207. The shaft 208 is rotatably connected to the frame 101. The wheel shaft 205 is fixedly connected to the output shaft of the motor 307. The motor 307 is fixedly connected to the frame 101.

[0022] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific shaft 208 described in the above embodiments. For example, a bearing ring is provided at the connection between the shaft 208 and the frame 101. The purpose of this setting is to facilitate reducing the damping of its rotation through this setting, thereby avoiding shaft breakage.

[0023] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific motor 307 described in the above embodiments. For example, the motor 307 should be selected as a motor with adjustable multi-speed. The purpose of this setting is to facilitate adjusting the output speed of the motor to thereby adjust the linear movement speed of the baffle 202.

[0024] Specifically, a pulley A209 is fixedly connected to the shaft 208. The pulley A209 is in transmission connection with a belt 301. The other end of the belt 301 is in transmission connection with a pulley B302.

[0025] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific pulley A209 and pulley B302 described in the above embodiments. For example, the pulley A209 and pulley B302 should have relatively deep pulley grooves.

[0026] Specifically, a connecting rod 303 is fixedly connected to the center of the pulley B302. The connecting rod 303 is rotatably connected to the frame 101.

[0027] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific frame 101 described in the above embodiments. For example, sealant strips are provided at the gaps on the frame 101. The purpose of this setting is to facilitate preventing smaller plastic particles from being stuffed into it through this setting.

[0028] Specifically, a gear 304 is fixedly connected to the connecting rod 303. The gear 304 is meshed with a gear ring 305. The gear ring 305 is fixedly connected to a cutter head 306. The cutter head 306 is rotatably connected to the frame 101.

[0029] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific cutter head 306 described in the above embodiments. For example, the cutter head 306 should be close to the frame 101. The purpose of this setting is to facilitate reducing the distance between the cutter head 306 and the frame 101 through this setting, thereby avoiding the subsequent plastic rod from bending and deforming during cutting.

[0030] In the embodiment of the present utility model, relevant technicians respectively place the plastic rods cooled by water passing through into the mesh holes of the frame 101, start the motor 307 and simultaneously start manually pushing the plastic rods. At this time, the motor 307 drives the axle 205 fixedly connected to its output shaft to rotate synchronously. At this time, the bevel gear A 206 fixedly connected to the axle 205 starts to rotate, so that the bevel gear A 206 drives the bevel gear B 207 meshed with it to start rotating, and the bevel gear B 207 drives the shaft 208 fixedly connected to its axis to rotate synchronously, so that the shaft 208 drives the pulley A 209 fixedly connected to it to start rotating, and the pulley B 302 starts to rotate synchronously with the pulley A 209 under the cooperation of the belt 301 drivingly connected to it, so that the connecting rod 303 drives the gear 304 fixedly connected to its top to start rotating, and the gear 304 drives the gear ring 305 meshed with it to start rotating, and the gear ring 305 drives the cutter head 306 fixedly connected to it to rotate synchronously. Thus, when the plastic rods are pushed out from the mesh holes on the frame 101, the plastic rods can be cut into plastic pellets by the cyclic rotation of the cutter head 306, and the plastic pellets fall on the mesh plate 201. At the same time, when the axle 205 rotates, it drives the eccentric wheel 204 fixedly connected to it to rotate synchronously, so that the eccentric wheel 204 drives the push rod 203 rotatably connected to its eccentric part to rotate synchronously, so that the push rod 203 starts to push the baffle 202 hinged to it, and the baffle 202 starts to reciprocally slide along its connection with the frame 101, so that the plastic pellets on the mesh plate 201 start to roll on it under the action of inertia, avoiding the accumulation of plastic pellets. At the same time, the qualified plastic pellets can fall along the mesh holes on the mesh plate 201, so as to screen the plastic pellets and avoid unqualified plastic pellets being mixed in them.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0032] The so-called fixed connection in this application means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0033] (1) Detachable connection: Fix components together using screws, splines, wedge pins, etc. This connection method can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, and wedge pins), and they must be tightened properly.

[0034] (2) Non-detachable connection: Mainly refers to welding, riveting, and mortise fitting, etc. Since forging, sawing, or oxygen cutting is required to disassemble during maintenance or replacement, spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0035] The sliding connection referred to in this application means that a component can slide along a linear trajectory, and the hinge connection referred to in this application means that a component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge connection referred to in this application can also be damped, enabling the component to have the ability to maintain at the desired position.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
