Description

Technical Field

[0002] Plastic particles are semi-finished products of plastics, which are used to facilitate the storage, transportation and injection molding of plastics. However, in the actual production process, the plastic particles produced may be uneven in size due to temperature changes and vibrations in the granulator. These plastic particles of uneven sizes will affect the mixing ratio during injection molding, resulting in uneven melting distribution of the mixed materials of the injection molded parts, which in turn affects the quality of the injection molded parts. Therefore, in order to test the production stability of the granulator, it is necessary to screen the plastic particles it produces at any time. However, the existing screening machines are not only complex in structure and inconvenient to start and stop flexibly, but can only screen out two plastic particles of different sizes at the same time, and the screening efficiency is low.

[0031] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0032] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0033] As shown in the attached drawings, a simple plastic particle screening machine comprises an outer shell 1, in which a plurality of screening components are arranged in sequence along the vertical direction, and the plurality of screening components are connected through a transmission mechanism;

[0034] The screening assembly includes a pair of supporting beams 21 extending parallel to each other and obliquely, a first elastic member 22 connecting the supporting beams 21 and the outer shell 1, a cross beam 23 integrally connected between the pair of supporting beams 21, and a screening plate 24 detachably connected between the pair of supporting beams 21;

[0035] The inner side wall of the outer shell 1 is provided with a vertically extending guide rail 25, and the support beam 21 is slidably connected to the guide rail 25;

[0036] The transmission mechanism includes a transmission rod 31 extending vertically and slidingly connected to the outer shell 1. A transmission part 311 abutting against the support beam 21 is formed on the transmission rod 31. The bottom end of the transmission rod 31 abuts against an eccentric wheel 32. The eccentric wheel 32 is integrally connected to a driven wheel 34 via a rotating shaft 33. The rotating shaft 33 is rotatably connected to the outer shell 1. The driven wheel 34 is connected to an actuating wheel 36 via a transmission belt 35. The actuating wheel 36 is rotatably connected to the outer shell 1. A rotating handle 37 is provided on the actuating wheel 36.

[0037] The working principle of this embodiment is:

[0038] When in use, the user pours the plastic particles to be screened into the hopper 12, and then rotates the handle 37 to drive the actuating wheel 36 to rotate. Under the action of the transmission belt 35, the driven wheel 34 also rotates and drives the eccentric wheel 32 to rotate, so that the transmission rod 31 abutting against the eccentric wheel 32 jumps up and down. In this way, the support beam 21 abutting against the transmission part 311 of the transmission rod 31 also drives the screen plate 24 to jump up and down, thereby achieving the screening of the plastic particles.

[0039] It can be understood that, in this embodiment, the apertures of the screen plates 24 of the multiple groups of screening components gradually decrease from top to bottom.

[0040] Preferably, an inner side wall of the support beam 21 is provided with a mounting groove 211 slidably connected to the sieve plate 24 , and a locking structure acting on the sieve plate 24 is provided on the cross beam 23 .

[0041] Preferably, the locking structure includes an installation cavity opened on the beam 23, a locking pin 41 is slidably connected in the installation cavity, a second elastic member 42 is connected between the locking pin 41 and the beam 23, the bottom end of the locking pin 41 extends to the bottom of the beam 23 and is provided with a pulling portion 411, a locking hole 241 adapted to the locking pin is opened on the screen plate 24, and a pull handle 242 is provided at the bottom end of the screen plate 24.

[0042] Preferably, the cross beam 23 is disposed at the high end of the support beam 21 , and a door panel 11 is hingedly connected to one side of the outer shell 1 close to the high end of the support beam 21 .

[0043] Specifically, after the user opens the door panel 11, the user pulls the locking pin downward through the pulling portion 411 to make the locking pin withdraw from the locking hole 241. Subsequently, the user can remove the sieve plate 24 from the mounting groove 211 by means of the pull handle 242 to replace the sieve plate 24.

[0044] Preferably, a feeding hopper 12 is provided at the top of the outer shell 1, a material guide plate 5 is integrally connected to the lower end of the support beam 21, and a through hole 13 for the material guide plate 5 to pass through is opened on the outer shell 1.

[0045] Preferably, a plurality of lockable casters 6 are provided at the bottom end of the outer shell 1. It should be noted that since the specific structure of the casters 6 is well known to those skilled in the art, no further description is given in this specification.

[0046] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
