Problems solved by technology

[0007] The present invention provides a tester for the rebound rate of coarse-pore high-resilience sponge, one of which aims to improve the working efficiency of the staff, and solve the problem that most of the existing testers are equipped with dust removal mechanisms to avoid the influence of dust accumulation The normal use of the tester, but the existing dust removal mechanism is difficult to replace the filter plate, which makes the work efficiency of the staff lower when replacing; another purpose is to solve the lack of shock absorption function of the existing tester , when the tester vibrates, it may cause the tester to overturn, which directly affects the service life of the tester. At the same time, the damage of the tester will affect the test efficiency, so as to ensure the test efficiency of the tester. ; Another purpose is to solve the problem that when the tester works for a long time, more heat will be generated inside, and the accumulation of heat will increase the temperature inside the body, thereby accelerating the aging speed of some internal parts, thereby reducing the tester. The problem of service life, in order to achieve the effect of improving the service life of the tester

Abstract

The invention discloses a rebound rate tester for coarse-hole high-rebound sponge, and relates to the technical field of sponge detection.The tester comprises a tester body, a damping mechanism is arranged at the bottom of the tester body, a dust removal mechanism is arranged at the top of the damping mechanism, a cooling mechanism is arranged on the right side of the tester body, and the dust removal mechanism comprises a dust removal shell; and an electromagnet is arranged in the dust removal shell. Through cooperation of a filter plate, a slide block and an electromagnet, the filter plate is pushed to move after the slide block is aligned with a slide groove, and the slide block is fixed through the moment generated after the electromagnet is electrified after the filter plate moves to a proper position, so that the problems that most of existing testers are provided with dust removal mechanisms to avoid influence of dust accumulation on normal use of the testers, and the test efficiency is high are solved. However, according to an existing dust removal mechanism, the filter plate is difficult to replace, so that the working efficiency is low when the workers replace the filter plate, and the effect of improving the working efficiency of the workers is achieved.

Description

technical field [0001] The invention relates to the technical field of sponge detection, in particular to a rebound rate tester for coarse-pore high-resilience sponges. Background technique [0002] High-resilience sponges have always been favored for their mechanical properties. Compared with general foam products, they have higher elasticity, lower hysteresis loss and higher compression load ratio. High-resilience, comfortable and breathable sponges Active, high molecular weight polyether polyol foamed, widely used in sofa cushions, backrests, mattresses and office seats, etc. Compared with similar products, it has better practicability and applicability, and is more With good market development prospects, the rebound rate of the sponge has become an important indicator. The rebound rate tester is usually applied to a coarse-hole high-resilience sponge in the process of rebound rate testing. [0003] There are following problems at prior art: [0004] 1. Most of the exis...
