Description

Technical Field

[0001] The present application relates to the technical field of papermaking equipment, and in particular to a raw material conveying device for wet-forming single-layer paper. Background Art

[0002] The wet-laid papermaking process utilizes raw materials such as water, cellulose, and additives to produce paper. The basic principle is to mix cellulose and other raw materials in a specific proportion to form a pulp. This pulp is then filtered through a filter such as a screen or felt, pressed, and dried to form paper. Using a screen to filter the pulp ensures an even distribution of fibers throughout the paper, preventing clumping of fibers that could affect the uniformity and strength of the paper.

[0003] Patent publication number CN219216843U discloses a paper bag production raw material conveying device. In this device, a rotating screen is provided to filter out bulky raw materials. The bulky raw materials can enter a collection box through a discharge port and a guide plate for collection. However, workers need to remove the collection box to disperse the agglomerated materials in the collection box, which is inconvenient. Utility Model Content

[0006] In the above technical solution, the material enters the box through the feed port and is filtered by the filter. The agglomerated material can stay on the surface of the filter. The agglomerated material is pushed out of the box from the discharge port by the pushing component and falls into the mixing box. The cutting motor can drive the cutting blade to rotate to cut the agglomerated material and then disperse the agglomerated material.

[0007] Furthermore, the pushing assembly includes a push plate and a driver for driving the push plate to slide horizontally and linearly, and the push plate can push the agglomerated material out of the box through the discharge port.

[0008] In the above technical solution, the driver can drive the push plate to slide horizontally and linearly along the upper surface of the filter screen to push the agglomerated materials out of the box.

[0009] Furthermore, a discharge hopper is provided in the box and below the filter screen, the discharge hopper is connected to a discharge barrel, a feeding auger is provided in the discharge barrel, the feeding auger is driven to rotate by an auger motor, and the feeding auger is used to deliver the material out of the box from the opening of the discharge barrel.

When the value detected by the weighing sensor is greater than the preset value, it means that there is a lot of block material accumulated on the surface of the filter. At this time, the driver can drive the push plate to slide horizontally and push the agglomerated material out of the box.

[0015] Furthermore, a receiving bucket is provided at the discharge port, and the receiving bucket is connected to the interior of the mixing box through a pipeline.

[0016] In the above technical solution, a receiving bucket and a pipe are provided so that the material pushed out by the push plate can accurately enter the mixing box.

[0017] Furthermore, a material transfer block is installed on the upper surface of the filter screen, and a slope is formed on the material transfer block.
