An information core material spot welding machine is arranged on the left side of the core material guide starting machine. By theadoption of the production technology of the sealing strip production line, the accurate and controllable parameters are fully realized, each supporting equipment is equipped with a sensor, and highlyintegrated control is adopted; and the parameters in the production processes are well controllable, the operation is convenient, the response is quick, the convenience of changing the whole production technology is facilitated, and the production efficiency is improved. The previous cylinder transmission of the core material storage machine is changed into motor transmission which is similar toelevator transmission. Due to the change of the scheme, the up-and-down lifting of guide wheels is more stable and safer, and the stable output of core materials is facilitated.

The invention discloses a 5G communication base station installation device with noise reduction and temperature reduction functions, including a box body, a pump cylinder, a liquid storage tank and a base station body. The pump cylinder is connected with a lifting seat through a vibration spring, and the base station body is in the process of working It will vibrate and generate noise, which will cause the vibrating spring to vibrate and drive the lifting seat to vibrate. Since the lifting seat is made of permanent magnets, the spiral magnetic induction coil moves relative to the lifting seat, and then the spiral magnetic induction coil cuts the magnetic induction line of the lifting seat. In turn, the induction current is generated on the spiral magnetic induction coil, thereby converting the vibration noise generated when the base station is working into electrical energy, reducing the transmission of noise. The tank and the pump barrel are filled with coolant. The pump barrel and the liquid storage tank are connected through the liquid inlet pipe and the liquid outlet pipe. When the electromagnet is energized, the opening size of the ventilation hole can be changed. Flow in the outlet pipe.
