Embodiment 1

[0020] This polyurethane sponge waste is prepared into the regenerated sponge method, it is characterized in that the preparation steps are as follows:

[0021] 1) The polyurethane sponge waste is crushed by a crushing machine into small particle sponge waste with a particle diameter of 1-20mm.

[0022] 2) Measure the small particle sponge waste in batches.

[0023] 3) Add glue batch by batch and mix evenly. The amount of glue added is 5-20% of the sponge waste by weight.

[0024] 4) Apply pressure and bond to form a recycled polyurethane sponge block.

Embodiment 2

[0026] see figure 1 , the polyurethane sponge waste is prepared into a regenerated sponge device, which is used for the above method to prepare a regenerated sponge, and is characterized in that it includes the following process equipment:

[0027] 1) Polyurethane sponge crushing process equipment (I): a crushing machine (I-2) with conveying and unloading equipment (I-1) and a powerful discharge device A (I-3) to realize the crushing of polyurethane sponge waste into granules Small particle sponge waste with a diameter of 1~20mm.

[0028] 2) Batch metering process equipment (II): intermittent storage batch metering device (II-2) with small particle sponge waste feed pipe (II-1) and powerful discharge equipment B (II-3). Realize intermittent storage and metering of small particle sponge waste in batches.

[0029] 3) Adding glue batch by batch and mixing process equipment (III): Stirring device (III-3) with upper feeding pipe (III-1) and glue adding mechanism (III-2), and a sw...

Abstract

The invention relates to a method and device for preparing regenerated sponges by polyurethane sponge wastes. The method comprises the following operation steps: 1) sponge wastes are crushed to smallparticles; 2) the small particles of the sponge wastes are metered in batches; 3) glue is fed gradually for uniform mixing; and 4) regenerated sponge blocks are bonded through pressing. The device comprises equipment of four procedures. The method can prepare sponge leftover wastes generated in the sponge product production process to the regenerated sponge blocks for such products as sponge spring mattresses and cushions, so that the production waste is reduced, the cost is reduced, meanwhile, the environment pollution possibly caused by the sponge wastes is reduced, production enterprises are more environment-friendly, and more energy is saved.

Description

technical field [0001] The invention relates to a method and a device for preparing recycled sponge from polyurethane sponge waste. Background technique [0002] During the production process of the sponge product factory, a large amount of sponge waste will be produced. It takes a lot of manpower and financial resources to deal with the sponge waste. There is no ideal treatment method, and it is difficult to reuse the waste. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a method and device for preparing recycled sponge from polyurethane sponge waste, so as to achieve waste reuse and increase production efficiency. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A kind of polyurethane sponge waste material is prepared into the regenerated sponge method, it is characterized in that the preparation steps are as follows: ...
