Description

Technical Field

[0001] The utility model belongs to the technical field of superhard material diamond synthesis, and particularly relates to a propulsion device suitable for grinding pyrophyllite square blocks. Background Art

[0002] Pyrophyllite blocks are made of pyrophyllite powder after mixing, pressing, baking, and milling. The pyrophyllite block product is square in shape and circular in inner cavity. The grinding equipment uses a desktop drilling and milling machine. The strength before baking is very low. When the desktop drilling and milling machine is used to grind the height size, a lot of grinding occurs. Therefore, the pyrophyllite block is solidified and baked to increase the strength before milling.

[0003] Although this working method increases the strength of talc and solves the problem of grinding, it also has disadvantages: 1. There is repetitive work: after pressing and forming, a special person is required to put it on the plate and circulate it; after roasting, a special person is required to mill and grind it, and a special person is required to put it on the plate again; 2. Pressing and grinding are not completed in the same area and at the same time, and there are communication difficulties in feedback of quality problems; 3. The height and size consistency of products ground by desktop drilling and milling machines is poor; 4. The structure of desktop drilling and milling machines is complex and difficult to maintain.

[0004] In order to solve the problem that talc square blocks cannot be ground before roasting, it is necessary to develop a system suitable for grinding talc square blocks before roasting. The transportation of talc square blocks is also a problem. The commonly used round turntable conveying system can easily break the four corners, and the roller conveying system can easily crush the product due to its insufficient strength. Therefore, the conveying system also needs to be improved. Utility Model Content

A first push plate is fixed at the head end of the first cylinder, and a first signal detector and a first baffle parallel to the working direction of the first cylinder are correspondingly provided at the end of the conveying direction of the transmission belt A.

[0009] The second cylinder is arranged in parallel and spaced below the transmission belt A, and its working direction is perpendicular to the working direction of the first cylinder and a second baffle is provided at its lower end, and a second signal detector and a third signal detector are provided at the left and right ends of the second baffle respectively.

[0010] When the material is horizontally transported to the first baffle via transmission belt A, the first signal detector detects the signal and transmits it to the control system to control the first cylinder to push the material downward to the second baffle. The second signal detector located on the outside detects the signal and transmits it to the control system to control the second cylinder to push the material to the left to the entrance of the grinding equipment. The third signal detector located on the inside detects the signal and transmits it to the control system to control the grinding equipment to start working.
