The invention discloses a distribution box protection system and a distribution box thereof, which relate to the technical field of distribution boxes and have the advantages of setting a protection device outside the distribution box and reducing man-made damage to the distribution box. The main points of the technical scheme are as follows: The first connection frame arranged around the distribution box and fixed on the ground, the first connection frame is square and is provided with vertical vertical rods at the four corners, and the four vertical rods pass through The second connection frame is connected, and the second connection frame is slidingly connected on the four vertical rods. When the second connection frame moves away from the first connection frame, the connection between the first connection frame and the second connection frame There is a protective piece between them, and when the second connecting frame is moved to a desired position, the vertical rod is provided with a limiting piece that limits the position of the second connecting frame.

The invention discloses an applying method of silicon rubber adhesive in optical change welding goggle adherence. It uses silicon rubber adhesive between filer part and crystalline liquid light valve to do adherence, and then extracts the air and eliminates the bubble between them. The silicon rubber adhesive adopts normal temperature reaction to modulate.

The invention discloses a production line control system and a control method thereof and relates to the technical field of control. The production line control system comprises a programmable logic controller (PLC) system and a main server. The PLC system comprises multiple work stations connected to the main server. The production line control system further comprises a radio frequency identification device (RFID) radio frequency read-write system. The RFID radio frequency read-write system comprises information reading points and RFID labels, wherein the information reading points are arranged on production lines, and multiple tool plates are further arranged on the production lines, and the RFID labels are written on the multiple tool plates. The information reading points read data information in the RFID labels on the tool plates and transfers the data information to the main server. Due to the fact that the production line control system enables the PLC system and the RFID radio frequency read-write system to be compatible, control of a production device and acquisition of the product data information are synchronously performed, information transmission between two sub-systems is achieved, and the purpose of common control of the production line is achieved.

The invention relates to an automatic tab bending and conveying mechanism for a nickel starting sheet, and belongs to the technical field of metallurgical machinery. The mechanism comprises a portal frame, a guide rail component, a pulley component, a linear guide cylinder component, a sucker assembly component, a pneumatic hammer component, a tab storage frame component, a tab treatment part component, a pneumatic switching mechanical hand component, an underframe and a mechanical hand sliding rail component. According to the mechanism, the labor intensity of a worker can be reduced, manual damage to a workpiece can be reduced, and higher applicability is achieved; the mechanism is more normative and low in bending reject rate; the mechanism can work safely and reliably, and tabs are uniformly and stably stressed; the whole mechanism is easy to disassemble and overhaul, the parts are common, and are not required to be maintained by a professional person, so that the mechanism is low in cost; human errors can be greatly reduced, working efficiency can be improved, and the requirements of automatic production are met.

A sheathed circular truncated conical filter press comprises an outer circular truncated conical sleeve (5), and an inner circular truncated conical sleeve (9) arranged at the middle part of the outer circular truncated conical sleeve (5). A filter press rubber sleeve (6) is arranged on the inner wall of the outer circular truncated conical sleeve (5). Small holes are evenly distributed on the inner circular truncated conical sleeve (9). Filter cloth (8) is arranged on the outer wall of the inner circular truncated conical sleeve (9). Air intake pipes (11) are arranged at two sides the wall of the outer circular truncated conical sleeve (5). An inner sleeve water outflow pipe (3) is arranged at the bottom of the inner circular truncated conical sleeve (9). A discharge plate (13) is arranged at the upper part of a circular truncated conical filter chamber (7). Multiple discharge holes (24) are provided in the discharge plate (13). A feeding pipe (15) entering the interior of the outer circular truncated conical sleeve (5) is arranged at one side of the upper cover (14), and high-pressure air intake pipes (18) entering the interior of the inner circular truncated conical sleeve (9) and the interior of the outer circular truncated conical sleeve (5) are arranged at the other side of the upper cover (14). A filter press water outflow pipe (1) connected to the inner sleeve water outflow pipe (3) is arranged on a bottom cover (4). The filter press dehydration is implemented by using high pressure air; fine coal grains are retained inside the circular truncated conical chamber and formed into filter cakes; the filter cakes are discharged when the bottom cover opens automatically. The whole filter press process is easy to implement, and has few maintenance and high efficiency; the solid-liquid separation effect is good; and the energy consumption is low.
