Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive particle screening, in particular to a screening device for hot melt adhesive particle production. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Hot melt adhesive particles are defined into different grades when they are sold. Each grade corresponds to a different diameter range of hot melt adhesive particles, so that consumers can distinguish and purchase them. Therefore, a screening device for hot melt adhesive particle production is needed.

[0003] According to a screening device for hot melt adhesive particle production disclosed on the patent website (authorization announcement number: CN220348819U), "a screening device for hot melt adhesive particle production includes a support frame, a vibrator, a support frame, and a feeding port. The support frame is provided with a plurality of screening boxes at intervals in the vertical direction. The bottom of each screening box is provided with a penetrating screen hole. The apertures of the screen holes on the plurality of screening boxes gradually decrease from top to bottom. The lower end of each screening box is provided with a bottom plate. The two sides of the bottom plate are respectively slidably matched with the support frame. The bottom plate is provided with a locking position, and the locking position is matched with a locking piece; after the bottom plate moves relative to the support frame, the locking piece can be inserted into the locking position through the support frame to fix the bottom plate on the support frame. In this screening device, when the hot melt adhesive particles are screened by the top screening box, the hot melt adhesive particles with larger particle sizes will be retained in the top screening box, and the hot melt adhesive particles with smaller particle sizes will pass through the screening holes of the top screening box and enter the screening box below. Therefore, through the sequential screening of the above structure, hot melt adhesive particles of different grades can be screened out. "

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, through the provision of multiple screening boxes, the apertures of the sieve holes on the multiple screening boxes gradually decrease from top to bottom. Since the apertures of the sieve holes on the screening boxes decrease successively from top to bottom, hot melt adhesive particles of different grades can be screened out through the sequential screening of the above structure. However, in actual use, a lot of dust will adhere to the surface of the hot melt adhesive particles during the production process. During the screening process, the dust will float according to the screening vibration, thereby affecting the health of the staff. Moreover, after the screening is complete, the dust will still adhere to the surface of the hot melt adhesive particles after falling down. Therefore, the hot melt adhesive particles still need to be dust-removed subsequently, which is time-consuming and labor-intensive. Therefore, it is necessary to improve a screening device for the production of hot melt adhesive particles to solve the above problems. Utility Model Content
