Description

TECHNICAL FIELD

[0001] The utility model relates to high polymer water absorption material crushing technical field, concretely relates to a high polymer water absorption material crusher. BACKGROUND

[0002] At present, with the development of society, the improvement of people's living standards, people not only enjoy material life, but also constantly pursue spiritual life, more and more people yearn for natural relaxation, and raising pets gradually becomes a fashion, pets play a more and more important role in people's life, and people's requirements for pet life quality are also higher and higher. Due to the limitation of living environment, pet excretion has been a problem for pet lovers. The use of pet urine pad can facilitate people to clean the excrement of pets. The internal absorption layer of the pet urine pad is generally composed of wood pulp and high molecular water absorption material. The wood pulp is used to lock water, and the high molecular material provides strong water absorption capacity. High molecular water absorption material needs to be crushed during the production of pet urine pad.

[0003] In the prior art, a pair of roll crushers are usually used to crush high molecular water absorption material. A waterproof layer belt 4 is arranged below the roll crusher. The two ends of the waterproof layer belt 4 are fixedly connected to the unwinding roller and the winding roller respectively. When the roll crusher works, the winding roller continuously winds the waterproof layer belt 4, and the unwinding roller unwinds the waterproof layer belt 4 wound on the surface of the unwinding roller, so that the waterproof layer belt 4 is kept in a moving state. The high molecular water absorption material crushed by the roll crusher falls on the waterproof layer belt 4 and is conveyed to the outside of the roll crusher by the waterproof layer belt 4. A flattening roller is arranged above the waterproof layer belt 4. When the waterproof layer belt 4 conveys the high molecular water absorption material, the high molecular water absorption material passes through the gap between the flattening roller and the waterproof layer belt 4. The flattening roller contacts the high molecular water absorption material and flattens the high molecular water absorption material on the waterproof layer belt 4, facilitating subsequent processing of the high molecular water absorption material.

[0004] When the crushing roller of the roll crusher crushes the high molecular water absorption material, the surface of the crushing roller cannot be completely smooth. When the crushing roller crushes the high molecular water absorption material, the crushing roller is easy to form adhesion with the surface of the raw material, so that part of the high molecular water absorption material adheres to the crushing roller, which not only affects the crushing quality of the plastic, but also damages the crushing roller. At the same time, it is difficult to crush the high molecular water absorption material into a particle size meeting the requirements of subsequent processing only by using the roll crusher. In view of this, we propose a high molecular water absorption material crusher. UTILITY MODEL CONTENTS

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This polymer water-absorbing material crusher has multiple crushing rollers inside the housing. When the polymer water-absorbing material falls into the gap between two crushing rollers, the two crushing rollers rotating in opposite directions initially crush the polymer water-absorbing material. At the same time, a crushing barrel and crushing wheel are set below the crushing rollers. The initially crushed polymer water-absorbing material will fall into the gap between the crushing barrel and the crushing wheel, so that the crushing wheel and the crushing barrel can perform secondary crushing of the polymer water-absorbing material, thereby improving the crushing quality of the polymer water-absorbing material.

[0014] 2. This polymer water-absorbing material crusher has a horizontally reciprocating brush installed under the crushing roller. When the crushing roller crushes the polymer water-absorbing material, relative sliding occurs between the crushing roller and the brush, causing the brush to brush off the polymer water-absorbing material adhering to the crushing roller. At the same time, the horizontally reciprocating brush shakes off the polymer water-absorbing material, preventing the brush from reducing its cleaning effect. This achieves automatic cleaning of the crushing roller, ensuring the crushing quality of the polymer water-absorbing material and improving the service life of the crushing roller.
