Description
Technical Field
[0001] The invention relates to the technical field of glass product manufacturing, and in particular to a raw material conveying device for glass product manufacturing. Background Art
[0002] Glass products are a general term for daily necessities and industrial products made from glass as the main raw material. Glass is a relatively transparent solid substance that forms a continuous network structure when melted. Its viscosity gradually increases and hardens during the cooling process. It is a non-crystalline silicate non-metallic material. In the production process of glass products, large quantities of raw materials need to be transported, and corresponding conveying devices are needed for this purpose.
[0003] Most of the existing conveying devices are simple conveyor belts. When using this conveyor belt to convey glass product raw materials, since the raw materials are mostly small fragments and powders, rolling and sliding are prone to occur during the conveying process, and then the raw materials will fall off the conveyor belt. At the same time, when the stored raw materials are placed on the conveyor belt and directly transported to the production equipment, these raw materials are prone to sticking during storage, and then a large amount of raw materials are gathered into large pieces that are inconvenient to process, which will affect subsequent production work.

At the same time, with the help of the discharge hopper 34, the fallen raw materials can be effectively collected, so that the raw materials can enter the production equipment more accurately and stably.
[0031] During the use of the present invention, after the assembly of the device is completed, the device is adjusted according to the height and other conditions of the production equipment, that is, the threaded tube 27 is rotated, and the threaded connection characteristics of the threaded tube 27 and the threaded column 28 are used to enable the threaded column 28 to push the base 1 to rise and fall to a suitable height relative to the chassis 26, and then the conveyor belt 6 and other structures can be raised and lowered to a suitable height, so that the device can smoothly cooperate with different production equipment to work, and then the rotation of multiple universal wheels 29 can be used to move the entire device to a specified position to align with the production equipment, so that the feed pipe 33 and the sleeve 39 are aligned with the production equipment, and at the same time, the staff can lift the sleeve 39 to a suitable position by sliding the sleeve 39 on the feed pipe 33, and then rotate the fixing bolt 43 to resist the feed pipe 33 to complete the fixing of the sleeve 39, so that the device can further stably and adaptably complete the feeding and conveying work of the production equipment;

At this time, the telescopic motor 17 will control the small grid plate 16 to move back and forth. When the small grid plate 16 is located in the reciprocating slot 14 and slides back and forth, the control block 23 and the control rope 21 will pull and push the swing frame 20 to swing back and forth around the control shaft 19, and then another control rope 21 and the control block 23 can be used to push and pull the large grid plate 15 to move back and forth. In this process, the large grid plate 15 can grind the large pieces of raw materials bonded together with its own large holes, and then use the small holes on the small grid plate 16 to complete the screening of the finely crushed raw materials. This can effectively prevent large pieces of bonded materials from being directly transported into the production equipment, affecting the quality and efficiency of production.
[0033] After the raw materials fall onto the conveyor belt 6, the conveyor belt 6 is divided into individual areas due to the presence of the partition plate 7. At the same time, the lifting plate 10 can always be stably attached to the conveyor belt 6 under the elastic force of the lifting spring 11. In this way, together with the isolation plate 8, the individual areas on the conveyor belt 6 can be effectively closed, thereby preventing the raw materials from slipping or rolling on the conveyor belt 6, so that the raw materials can be smoothly transported to the lower hopper 34 along the conveyor belt 6, and then separated from the conveyor belt 6 as the conveyor belt 6 rotates, and falls into the production equipment through the lower hopper 34, the lower pipe 33 and the sleeve 39, completing the stable and accurate raw material transportation work.
