Description

Uniform material distribution method for loose materials

Technical Field

The invention relates to the technical field of material distribution methods, in particular to a uniform material distribution method for loose materials.

Background

In the prior art, bulk material is usually dispensed from an upstream processing and refining device down into a downstream filling die by means of a dispensing nozzle. In the process of concrete material distribution, the cloth duckbill is higher than the height of a mould on the inner bottom surface of the forming mould, and loose materials are discharged into the forming mould at a constant speed through the cloth duckbill. The defects of the traditional cloth mode are as follows: due to the loose and indefinite material property of the loose materials, after the materials are discharged at one time through a material distributing duckbill in a forming die with a certain height, the upper surface of the loose materials is in an uneven state (such as the upper surface of the loose materials after the materials are distributed for the first time in the attached figure 2 of the specification) after the loose materials are piled in the forming die, and the loose materials are difficult to be distributed uniformly. At this time, if the product is not processed, when the subsequent pressing process is directly performed, the product pressed by the loose materials must have defects such as surface pits, air holes and the like, and the quality of the finished product is low.

Therefore, how to reasonably improve the existing material distribution method and avoid the pit defect on the surface of the finished product is necessary for improving the quality and durability of the finished product.

Disclosure of Invention

The technical purpose of the invention is as follows: the uniform material distribution method for the loose materials is provided, so that the upper surfaces of the loose materials to be pressed in the forming die after material distribution are smooth and uniform, the defects of pits and the like on the surfaces of pressed products are avoided, and the quality of finished products is improved.

In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a method for even cloth of bulk material, includes cloth duckbilled and forming die, forming die be the rectangle structure, the cloth duckbilled sets up in forming die's inside, and the cloth duckbilled arranges along the width direction of rectangle forming die, the cloth method include following steps: lifting the duckbill for material distribution upwards to a height to be distributed, which is equal to the height of the loose materials from the inner bottom surface of the forming die; controlling the material distribution duckbill to distribute the material from the material distribution starting end to the material distribution stopping end at a constant speed along the length direction of the forming die; the cloth duck bill is lifted upwards by 1.5-2.5 mm in parallel; and controlling the material distribution duckbill to distribute the material from the material distribution stopping end to the starting end at a constant speed along the length direction of the forming die.

Preferably, the two ends of the cloth duckbill are in frictional contact with the inner sides of the length sides of the rectangular forming die.

Preferably, the height of the cloth duckbill is greater than that of the rectangular forming die.

Preferably, the height of the bulk material to be distributed in the forming die is 10-30 times of the parallel upward raised height of the duckbill for distributing.

The invention has the beneficial effects that:

1. according to the material distribution method, after the material is distributed in the forming die at a constant speed at one time, the material is lifted and reversely distributed again and scraped, so that the loose materials to be pressed stacked in the forming die can be trimmed to the upper surface to a certain degree, and the original loose materials with uneven surfaces after being distributed at one time are trimmed to the smooth and uniform surfaces by scraping. The improved material distribution method can fundamentally avoid the problem that defects such as pits, air holes and the like exist on the surface of a subsequent pressed product due to non-uniform material distribution in the prior art. Thereby improving the product quality and durability.

2. The material distributing method disclosed by the invention is simple in process, convenient to operate, free of the need of adding new auxiliary equipment, convenient to realize and good in practical effect.

Detailed Description

The detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings, and it should be noted that the detailed description of the embodiments is provided for the purpose of facilitating a full understanding of the technical solutions of the present invention, and should not be construed as a limitation to the scope of the claims of the present invention.

The utility model provides an even cloth method for loose material, includes cloth duckbilled 1 and forming die 2, forming die 2 be the rectangle structure, cloth duckbilled 1 sets up in forming die 2's inside, and cloth duckbilled 1 arranges along the width direction of rectangle forming die 2, the inboard frictional contact on both ends and the 2 length limits of rectangle forming die of cloth duckbilled 1, cloth duckbilled 1 highly is greater than the height of rectangle forming die 2.

The cloth distributing method comprises the following steps: the cloth duckbill 1 is lifted upwards to a height which is equal to the height of the loose materials 3 to be distributed from the inner bottom surface of the forming die 2; controlling the material distribution duckbilled 1 to distribute material from the material distribution starting end 4 to the material distribution stopping end 5 at a constant speed along the length direction of the forming die 2; the cloth duck bill 1 is lifted upwards by 1.5-2.5 mm (the height is usually 1/10-1/30 of the height of the loose materials 3 to be distributed in the forming die 2); the cloth duckbilled 1 is controlled to be distributed to the starting end 4 from the cloth stopping end 5 at a constant speed along the length direction of the forming die 2.

The invention relates to a technology for uniformly distributing loose materials in a forming die. The technical problem that loose materials are difficult to be distributed uniformly in a distributing mode in the prior art is solved.

The process core of the material distribution method is that after the duckbill of the material distribution is improved by a small degree, the excess material distribution and the upper surface back scraping are carried out. As shown in the attached fig. 2 of the specification, specifically: the loose materials flow into the forming die through the cloth duckbilled cloth, and when the materials are distributed for the first time, the cloth duckbilled moves to the end of the die from the starting end of the cloth of the forming die at a uniform speed along the arrow direction at the upper part in the figure. Then, be on a parallel with forming die's upper surface upwards promote about 2mm, should promote highly can be according to the actual height condition of waiting to suppress loose material and decide, later, carry out the cloth for the second time, this cloth in-process, the cloth duckbill is advanced to forming die's initiating end at the uniform velocity from forming die cloth's termination end along lower part arrow direction in the picture, accomplish loose material's clout cloth promptly and scrape back, in order to evenly cloth the clout into forming die, and the upper surface is smooth, homogeneous.

The method has the characteristics of simplicity, practicability, no need of adding other auxiliary equipment, realization of the purpose of uniform material distribution in the forming die through simple improved material distribution operation, convenience in realization and good practical effect after being put into use.
