Description

Technical Field

[0001] The utility model relates to the technical field of light spar wall material production, in particular to a light spar raw material conveying system. Background Art

[0002] The traditional control system for receiving light spar raw materials uses a multi-stage screw conveyor to transport the light spar raw materials to the material storage bin, and then transports them to the electronic scale for weighing through the unloading screw conveyor, and then sends the fixed weight of light spar raw materials to the material distribution machine. However, the multi-stage screw conveyor needs to use multiple motors for sequential control to meet the requirements of the raw material receiving process. The multi-stage screw conveyor generates a lot of noise and the control process is complicated. In the absence of an excessive storage bin, the control process is not flexible enough, which is not conducive to the handling of abnormal production situations. Moreover, the weight distribution method of the material after weighing by the electronic scale will have cumulative errors in the continuous production process, and it is easy to malfunction when cooperating with the material distribution machine, causing production accidents.

[0038] The material distribution control unit 6 is used to control the material discharge, and includes a plurality of material distribution mechanisms, which include a raw material receiving bin, a material unloading screw conveyor 63, a transmission hose, a material distribution bin 62 and a transmission roller 61 from top to bottom, and a boron plate mold is provided on the transmission roller 61, and the boron plate mold is used to receive the material;

The material in the raw material transition storage unit 3 can be conveyed to the loading and lifting mechanism through the lower screw conveying mechanism 32. By controlling the three-way solenoid valve in the lifting unit 2 to select whether the raw material transition storage bin unit is put into operation, it is convenient to handle abnormal production situations.

[0042] Optionally, a rotary paddle level meter is provided in the raw material transition storage unit 3 for controlling the operating status of the upper and lower screw conveyors according to the storage amount of the material in the storage unit.

[0043] In this embodiment, the raw material transition storage unit 3 is provided with a rotary level meter according to the upper and lower limits of the material capacity. When the lower limit rotary level meter switch is closed, it means that the raw material transition storage unit 3 lacks materials and can be transported, the upper screw conveyor operates, and the materials transported by the lifting unit 2 are transmitted to the raw material transition storage unit 3 through the upper screw conveyor; when the upper limit rotary level meter switch is closed, it means that the raw material transition storage unit 3 is full of materials and transportation stops, and the upper screw conveyor stops operating.

The control system and the control of the various units are conventional means in the computer field, that is, simple improvements on the existing technology, which are implemented according to the adaptive modification of the structure of the present invention and do not affect the present invention.

[0050] The working principle of the utility model is as follows:

[0051] The utility model starts the light crystal raw material conveying system by sending a signal through the control system. After the raw materials prepared according to the formula at the raw material batching end are mixed evenly in the mixer, they are conveyed to the lifting unit 2 through the feeding screw conveying unit 1 at the mixing end. The lifting unit 2 conveys the materials to the raw material transition storage unit 3 or the conveying belt unit 4 according to the state of the three-way solenoid valve.

[0052] If the material is transported to the raw material transition storage unit 3, the material is transported to the raw material transition storage unit 3 through the upper screw conveying mechanism 31. After the material is full, it can be selected whether to send the material in the transition storage unit out through the lower screw conveying mechanism 32 and transport it to the conveyor belt unit 4 through the feeding lifting mechanism;

[0053] If the material is transported to the conveyor belt unit 4, the material enters the conveyor belt unit 4 and is driven by the conveyor belt unit 4 to be transported to the material distribution screw conveyor unit 5, and the material distribution screw conveyor unit 5 selects to transport the raw material to the 1# material distribution mechanism or the 2# material distribution mechanism of the material distribution control unit 6;

[0054] The raw material receiving bin of the fabric mechanism receives the raw material, and the rotary level meter in the fabric storage bin 62 sends a signal, indicating that unloading is required, and the unloading screw conveyor 63 starts to operate, and the material is transmitted to the fabric storage bin 62 through the metal hose. After the rotary level meter is closed, a stop signal is sent to the control system, and the unloading screw conveyor 63 stops with a delay; the transmission roller 61 starts to operate according to the set lateral dimension, and the fabric storage bin 62 unloads the material into the boron plate mold according to the set longitudinal height. The width direction of the light spar plate is determined by the boron plate mold, thereby realizing the volume control of the light spar plate; after the work is completed, a unloading completion response signal is sent, and the fabric control unit 6 enters the next round of working state.

[0055] To sum up, in the utility model, a light crystal stone raw material conveying system, a transmission belt replaces a multi-stage screw conveyor, thereby avoiding the sequential control of multiple motors of the multi-stage screw conveyor; the specification control of the product is achieved by controlling the cloth volume through the device, thereby avoiding the practical problems such as cumulative errors in the continuous production process of the weight cloth method after weighing with an electronic scale in the prior art, thereby improving the production accuracy.
