Description

Technical Field

[0001] This utility model relates to the field of raw material crushing technology, and in particular to a raw material crushing device for the production of polyethylene woven bags. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic used for packaging. Their raw materials are generally polyethylene, polypropylene, and other chemical plastic raw materials. Woven bags have a wide range of uses, mainly for packaging various items, and are widely used in industry.

[0003] A patent with publication number CN205761507U discloses a multi-stage crushing device for raw materials used in woven bag production. This patent includes a feeding hopper, an electric crushing wheel, an inclined slide plate, a discharge pipe, an electrically controlled valve, a crushing frame, a placement plate, a push plate, an electric push rod, a first slider, a first connecting rod, a first slide rail, a second connecting rod, a fixing block, a third connecting rod, a support rod, a motor, a disc, a first connecting rod, a second connecting rod, a mounting plate, a second slider, a second slide rail, a third connecting rod, a pressure block, a baffle, a right frame, a collection frame, a first support rod, a second support rod, a bottom plate, and a left frame. When it is necessary to crush the raw materials for woven bags, the raw materials are poured into the crushing frame. The motor is controlled to rotate, driving the disc to rotate, which in turn drives the first connecting rod to rotate. The pressure block moves downwards, crushing the raw materials in the crushing frame. When the pressure block moves downwards to a certain extent, the raw materials are continuously crushed. When the raw materials are crushed to a certain degree... When the pressure block returns to its initial position after reaching a certain point, the motor stops rotating, and the electric push rod extends, moving the push plate to the right, which in turn moves the crushing frame to the right. When the crushing frame moves to the right to a certain extent, it begins to slide towards the inclined slide plate. When the crushing frame hits the baffle on the inclined slide plate, the baffle stops the crushing frame, and the electric crushing wheel starts working. At the same time, the electric control valve opens, allowing the raw material in the crushing frame to fall into the feed hopper through the discharge pipe and be further crushed by the electric crushing wheel. The further crushed raw material falls into the collection frame through the feed hopper. When all the raw material in the crushing frame has fallen into the feed hopper, the electric control valve closes, and the crushing frame is manually returned to its original position. When all the raw material in the feed hopper has fallen into the collection frame, the electric crushing wheel stops working, and the collection frame is manually processed. However, the following problems still exist in this patent:

[0004] During the crushing process, the raw materials fall directly into the collection box after passing through the crushing roller, making it difficult to distinguish the uncrushed materials. This can easily lead to insufficient crushing of the raw materials, thus affecting the production of woven bags.

[0005] To address the above problems, a raw material crushing device for polyethylene woven bag production needs to be designed to overcome these issues. Utility Model Content
