Description

Technical Field

[0001] The utility model relates to the technical field of elastic particle processing, in particular to a novel screening mechanism for elastic particle processing. Background Technique

[0002] TPE particles are the abbreviation of thermoplastic elastomer particles. During the molding process of TPE elastomer particles, vulcanization is not required, and they can be directly molded by general thermoplastic molding equipment. Common molding methods such as injection molding, extrusion, blow molding, and casting can be directly used. The products produced by anti-silicone TPE plastic particles have a good hand feeling and can be non-toxic and odorless.

[0003] The "raw material screening device for the production and processing of disposable TPE gloves" disclosed in its application number "CN202020631534.5" "comprises a screening box, the lower end of the screening box is fixedly connected with a plurality of support feet, two feeding ports are symmetrically arranged at the upper end of the screening box, a second discharge port is arranged at the middle position of the lower end of the screening box, a screening mechanism is arranged inside the screening box, a material guiding mechanism for discharging materials is arranged inside the screening box, and a secondary screening mechanism is arranged inside the screening box". In the utility model, through the setting of the screening mechanism, the materials are preliminarily screened by the cooperation of the vibration motor and the tension spring. Through the setting of the secondary screening mechanism, the materials that are not completely screened for the first time can be screened again to ensure the full screening of the materials and improve the screening effect.

Although the vibration motor can achieve vibration screening, the excitation force will be directly transmitted to the screening box, which is likely to cause the screening box to shake and reduce its stability.

[0032] Embodiment 3:

[0033] The feeding assembly 18 includes a feeding pipe 1801 and a feeding hopper 1802. The bottom end of the feeding pipe 1801 is welded to one side of the top of the sieve box 1. The top end of the feeding pipe 1801 is welded with a feeding hopper 1802. A blower 1803 and an inclined impurity removal pipe 1805 are respectively arranged on both sides of the feeding pipe 1801. Through the feeding hopper 1802 for feeding, the material can enter the sieve box 1 through the feeding pipe 1801. During the free fall of the material, through the air supply of the blower 1803, the material can be subjected to air separation and impurity removal, and the impurities can be discharged through the inclined impurity removal pipe 1805. And the inclined impurity removal pipe 1805 can prevent the material from falling outside the sieve box 1 depending on its inclination angle;

[0034] On both sides of the feeding pipe 1801, there are respectively an air supply port 1806 and an impurity removal port 1807. The fan 1803 and the inclined impurity removal pipe 1805 are respectively welded to the air supply port 1806 and the impurity removal port 1807. The air supply port 1806 and the impurity removal port 1807 can ensure the air circulation.

[0037] During the screening process, the staff vibrates the slide plate one 2 through the vibration motor 5. The slide plate one 2 can transmit the exciting force to the inclined screening mesh one 901 and the inclined screening mesh two 905 through the vibration plate one 903 and the vibration plate two 904, which can ensure the screening efficiency, and the rubber strip one 8 and the rubber strip two 907 can prevent the exciting force from being transmitted to the screening box 1 through the slide plate one 2, the frame one 902 and the frame two 906.

[0038] At the same time, the damping shock absorber 4 can provide buffering and shock absorption for the screening box 1, avoiding the direct transmission of the exciting force to the screening box 1, reducing the vibration transmitted from the slide plate one 2 to the bottom end of the screening box 1 through the support column 3, and making the screening box 1 not easy to shake during the screening operation, which can improve its stability.
