Technical Field
[0001] This utility model relates to the field of granulator technology, specifically to a screenable plastic granulation device. Background Technology
[0002] In the plastic extrusion production process, plastic raw materials are melted and extruded through an extruder at high temperature. When the plastic melt comes out of the extruder die, it appears as a series of lines. After being cooled by a water tank, the molten plastic becomes a rigid plastic in the form of lines. At this point, the plastic has solidified from a molten state to a solid state and is then fed into a granulation device. The pressure roller group guides the plastic strip to the roller cutter, which cuts the plastic strip into multiple plastic granules.
[0003] The existing Chinese utility model patent 2020216711663 discloses a granulation device for screening plastic masterbatch. It uses two inclined screens below the roller cutter to screen the cut plastic masterbatch. This vertical screening method is relatively passive and is prone to screen blockage. At the same time, the flat screen is inconvenient to disassemble and cannot be changed in time according to the screening needs, which affects the screening efficiency and screening quality of the plastic granulation device. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a screenable plastic granulation device that can change the screen mesh size in a timely manner according to the screening needs, thereby improving the screening efficiency and screening quality of the plastic granulation device.
[0005] According to the technical solution provided in the embodiments of this application, a screenable plastic granulation device includes a granulator body, and a first screening component, a second screening component, a third screening component and a tail material collection component are provided at the discharge port on the machine casing. The first screening component, the second screening component, the third screening component and the tail material collection component are horizontally connected in parallel, so that the first screening component, the second screening component and the third screening component can be disassembled and assembled according to screening requirements.
[0006] The first screening component, the second screening component, and the third screening component have compatible structures, each including a screening box, a sieve cylinder, and two bearings. The sieve cylinder is horizontally installed inside the screening box, and the bearings are snapped onto both ends of the sieve cylinder so that the sieve cylinder can be rotated and installed inside the screening box via the bearings.
[0007] The drive mechanism, installed inside the housing, includes a rotation drive component, a drive gear, and a driven gear. The driven gear is mounted on a connecting cylinder, which is mounted on the housing via bearings. The connecting cylinder is snapped into the screen cylinder on the first screening assembly. The driven gear meshes with the drive gear, and the drive gear is fixedly connected to the output end of the rotation drive component, so that the rotation drive component drives the screen cylinder snapped into the connecting cylinder to rotate.
[0008] Furthermore, a number of positioning rods are provided on the left side of the screen cylinder, and a number of corresponding positioning grooves are provided on the right side of the screen cylinder. The positioning rods are engaged with the positioning grooves on the adjacent screen cylinders.
[0009] Furthermore, the bottom of the screening box is provided with a collection plate with grooves, which facilitates the collection of screened plastic masterbatch at the bottom of the collection plate.
[0010] Furthermore, a discharge pipe is also provided on the bottom side of the screening box. The discharge pipe is inclined and abuts against the bottom of the collection plate, so that the screened plastic masterbatch can be discharged through the discharge pipe.
[0011] Furthermore, the screening boxes on the first screening component, the second screening component, the third screening component, and the tailings collection component are connected and fixed by connectors.
[0012] Furthermore, the collection cylinder on the tailings collection assembly has a conical structure, and a second conveying plate is provided on the collection cylinder for conveying the screened plastic masterbatch into the collection plate.
[0013] Furthermore, a first conveying plate is provided inside the screen cylinder, and the first conveying plate is spiral in shape.
[0014] Furthermore, the screening box is also equipped with a transparent observation window, which allows for timely observation of the screening process.
[0015] Furthermore, the chassis is also equipped with a cutting mechanism, which is used to cut the extruded plastic masterbatch strips to complete the granulation of the plastic masterbatch.
[0016] Furthermore, a collection hopper is provided at the front end of the cutting mechanism on the chassis. The collection hopper collects the cut plastic masterbatch and conveys it to the feed pipe through the connecting pipe, so that the plastic masterbatch particles enter the screen cylinder on the first screening component from the feed pipe and rotate and move for screening inside the screen cylinder.
[0017] In summary, the beneficial effects of this application are as follows:
[0018] 1. By installing a detachable and snap-fit first screening component, second screening component, third screening component and tail material collection component on the plastic granulation device, the granulation device can change the mesh size of the screening sieve cylinder in a timely manner according to the granulation requirements, so that the plastic granulation device can be used for the production and screening of different types of plastic masterbatch.
[0019] Second, by setting the first screening component, the second screening component, the third screening component, and the tail material collection component into a horizontal structure, and connecting the first screening component, the second screening component, the third screening component, and the tail material collection component in a horizontal parallel arrangement, and driving the screen cylinders of different mesh sizes to rotate through a drive mechanism, the screening method of the original vertical flat screen is replaced, thereby improving the screening efficiency of plastic masterbatch in the plastic granulation device.

Each of the first screening component 120, second screening component 130, third screening component 140, and tailings collection component 150 contains a screen cylinder 122 with a gradually decreasing mesh size, allowing the cut plastic masterbatch to be screened within each screen cylinder 122, thereby improving the granulation efficiency of the plastic granulating device. Screening efficiency; simultaneously, the first screening component 120, the second screening component 130, the third screening component 140, and the tailings collection component 150 are horizontally connected in parallel, allowing the first screening component 120, the second screening component 130, and the third screening component 140 to be disassembled and assembled according to screening requirements, thereby improving the screening quality of the plastic granulation device; the first screening component 120, the second screening component 130, and the third screening component 140 have compatible structures, each including a screening box 121, a screen cylinder 122, and two bearings 12... 3. The screen cylinder 122 is horizontally installed inside the screening box 121, and bearings 123 are snapped onto both ends of the screen cylinder 122 so that the screen cylinder 122 can be rotated and installed inside the screening box 121 via the bearings 123; the drive mechanism 170 is installed inside the housing 110 and includes a rotation drive component 171, a drive gear 172 and a driven gear 173. The driven gear 173 is installed on the connecting cylinder 112, and the connecting cylinder 112 is installed on the housing 110 via the bearings 123. The connecting cylinder 112 is connected to the first screening assembly 120. The screen cylinder 122 is snapped into place, and the driven gear 173 is meshed with the driving gear 172. The driving gear 172 is fixedly connected to the output end of the rotation drive 171, so that the rotation drive 171 drives the driving gear 172 to rotate, thereby causing the driving gear 172 to drive the meshed driven gear 173 to rotate, so that the connecting cylinder 112 with the driven gear 173 installed rotates, and the screen cylinder 122, which is snapped into place with the connecting cylinder 112, rotates synchronously, so that plastic masterbatches of different diameters inside the screen cylinder 122 can be rotated and screened.
[0030] During the screening process of cut plastic masterbatch in the plastic granulation device, the plastic masterbatch strips processed through extrusion molding, cooling, and drying enter the granulation device and are cut by the cutting mechanism 111, so that the cut plastic masterbatch of different diameters enters the screen cylinder 122 on the first screening assembly 120 through the connecting pipe connected to the collection hopper. The first screening assembly 120, the second screening assembly 130, the third screening assembly 140, and the tail material collection assembly 150 are horizontally adjacent to each other through the connector 160. The screen cylinders 122 on the first screening assembly 120, the second screening assembly 130, the third screening assembly 140, and the tail material collection assembly 150 are sequentially connected to the positioning groove 1221 by the positioning rod 1222. The drive mechanism 170 is connected so that the rotating drive component 171 drives the drive gear 172 to rotate, thereby causing the driven gear 173 meshing with the drive gear 172 to rotate, which in turn causes the connecting cylinder 112, on which the driven gear 173 is mounted, to rotate. This causes the screen cylinder 122, which is positioned and engaged at the rear end of the connecting cylinder 112, to rotate synchronously. This allows plastic masterbatches of different diameters to be conveyed into the screen cylinder 122 and screened in screen cylinders of different mesh sizes. The masterbatches then enter the corresponding screening box 121 and slide from the grooved collection plate 1211 at the bottom of the screening box 121, so that the screened plastic masterbatches are discharged from the discharge pipe 1213. This improves the granulation screening efficiency and screening quality of the plastic granulation device.

The telescopic drive on the cutting mechanism 111 drives the cutter fixedly connected at the bottom to move continuously downward, cutting the plastic masterbatch strips after extrusion, thereby cutting the strip-shaped plastic masterbatch into granules and completing the granulation of plastic masterbatch.
[0039] As a preferred embodiment, please refer to Figure 2 and Figure 3 The front end of the cutting mechanism 111 on the casing 110 is provided with a collection hopper.
