Description

Technical Field

[0001] The utility model belongs to the technical field of polyester foam material production, and specifically relates to a polyester foam material screening and feeding device. Background Art

[0002] Polyester foam is a lightweight, highly elastic, compression-resistant insulation material. It is made of polyester fibers that are specially processed to form a structure with a large number of small bubbles. Polyester foam has good thermal insulation properties, so it is often used in products such as refrigerators, insulated boxes, and insulation boards. In addition, polyester foam has good compression resistance and can be used to cushion protective items during transportation.

[0003] In production, due to the purchase of polyester foam materials from different manufacturers, the raw material states are diverse. Some foam materials have large particles and carry some waste silk, which has a great impact on production. If the raw materials are pre-treated, screened and packaged separately before feeding, it will increase the labor cost. In response to this technical problem, the Chinese utility model patent with announcement number CN213468580U discloses a polyester foam material screening and feeding system, including a feeding bin, a platform and a screening machine. The screening machine is installed on the platform, and the outlet of the screening machine faces the feeding bin. The screening machine includes a shell, a bracket, a spring, a motor and an exciter. The bracket includes a base, a support and a motor support, and the base is installed on the platform; the shell includes two side panels, a bottom plate, a first outlet, a second outlet, a third outlet, a first screen and a second screen, a bottom end, a first screen and a second screen are provided between the two side panels, the second screen and the left ends of the two side panels are connected to the second outlet, and the second outlet extends to the top of the feeding bin; legs are provided at both ends of the outer side of the side panels, the lower end surface of the legs is connected to the upper end of the spring, and the lower end of the spring is connected to the upper end surface of the support; a hole is opened in the middle of the side panel and an exciter is provided, a motor is provided on the motor support, and the rotating shaft of the motor is connected to the exciter.

[0004] When the above technical solution is actually used, although it can screen the raw materials, the mesh of the screen will be blocked by part of the raw materials when it is in use, and the solution does not have a mechanism for cleaning the mesh, resulting in the need for manual cleaning of the screen later, which is labor-intensive and inefficient for the staff.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies.

[0006] Therefore, in order to solve the above problems, the utility model provides a polyester foam material screening and feeding device. Utility Model Content
