The present invention belongs to the technical field of steel structure welding, and specifically relates to a welding auxiliary positioning device for steel structure construction, including a positioning mechanism, etc.; the positioning mechanism is provided with at least four groups, and the steel column is limited by all the positioning mechanisms in cooperation. The present invention realizes that by magnetically attracting four fixing plates to the outer surface of the lower steel column, and then manually pushing four plugs in sequence, the four plugs are all moved to the upper surface of the lower steel column, and the plugs are locked by the corresponding elastic member I, and the upper steel column is limited by all the limit blocks, so that the upper steel column and the lower steel column remain flush, by twisting all the bolts until all the limit blocks are against the surface of the upper steel column, and then the clamp I is installed on the four fixing plates, and the clamp I is locked, so that the two steel columns are tightly held and the two steel columns are kept flush, thereby realizing auxiliary positioning of the two steel columns.

The invention provides an electric heating faucet. The electric heating faucet comprises a shell assembly, an electric heating pipe and an overheating protection assembly. A heating cavity is formed in the shell assembly, and the electric heating pipe is arranged in the heating cavity and fixed to the shell assembly. The overheating protection assembly is vertically arranged in the shell assembly located at the bottom of the heating cavity in a penetrating mode and is sealed with the shell assembly in the circumferential direction, the temperature sensing end of the overheating protection assembly abuts against the heating part of the electric heating pipe and conducts heat, and the electric heating pipe and the overheating protection assembly are both electrically connected with a control circuit board in the electric heating faucet; according to the invention, convenience can be brought to assembly of the overheating protection assembly and the electric heating tube, the production cost can be reduced, and in addition, the service life of the electric heating tube can be prevented from being shortened due to the influence of high welding temperature.

The utility model discloses waste heat recycling type film laminating equipment, which relates to the technical field of film laminating machines, and is characterized in that an equipment body comprises a preheating chamber, a heating chamber, a heat preservation chamber, a hot pressing roller and a heat recovery chamber which are sequentially arranged along the conveying direction of a film, and a plurality of heat conduction rollers which are respectively propped against the film and fabric are arranged in the heat recovery chamber; the two width sides of the preheating chamber are fixedly connected with heat conduction pipes communicating with the preheating chamber, the ends, away from the heat recovery chamber, of the heat conduction pipes are fixedly connected to the side wall in the width direction of the preheating chamber and communicate with the preheating chamber, and the heat conduction pipes drive hot air in the heat recovery chamber to enter the preheating chamber. According to the utility model, the temperature in the fabric and the film can be quickly guided out through the plurality of heat conduction rollers and dissipated in the heat recovery chamber, and the hot air in the heat recovery chamber is guided into the preheating chamber through the two heat conduction pipes which are obliquely arranged upwards, so that the film is preheated before entering the heating chamber; and therefore, the energy consumption of the equipment body during processing is reduced by recycling the waste heat.

This utility model discloses an extrusion puffing machine with a heating structure, including an upper tube body. A reduction motor is fixedly connected to the left side of the upper tube body, and a screw shaft is movably connected to the left side inside the upper tube body. The output end of the reduction motor extends into the interior of the upper tube body and is fixedly connected to the screw shaft. A heating structure for preheating the raw material is provided on the left side of the top of the upper tube body. This extrusion puffing machine with a heating structure has a heating tank. During processing, the raw material is introduced into the heating tank through the feeding port. The electric heaters on both sides of the heating tank are activated, conducting heat to the inside through the heat-conducting layer, thereby heating the raw material inside the heating tank. Simultaneously, the drive motor is activated, driving multiple sets of stirring rods to rotate via a rotating shaft. The rotation of the stirring rods stirs the raw material inside the heating tank, improving heating uniformity and solving the problem of not being able to preheat the raw material.

The utility model discloses a battery module heat-conducting glue coating system, the battery module heat-conducting glue coating system comprises a glue pump device, a glue pipe assembly, a temperature control device and a glue quantifying device, the glue pump device comprises a first pump assembly and a second pump assembly; the rubber tube assembly comprises a first rubber tube and a second rubber tube; the temperature control device comprises a first temperature control assembly and an auxiliary temperature adjusting assembly, the auxiliary temperature adjusting assembly comprises a heat exchange part, a water pump, a first sealing box and a first heat transfer pipe, the heat exchange part is arranged on the air outlet side of the first pump assembly and the air outlet side of the second pump assembly, the sealing box and the heat exchange part are both connected with the first heat transfer pipe, and the water pump is installed on the first heat transfer pipe. The first rubber pipe comprises a first branch pipe and a second branch pipe; the first pump assembly is communicated with the first sealing box through the first branch pipe; due to the fact that the auxiliary temperature adjusting assembly preheats the first material through the heat generated by the pump machine, and the first temperature control assembly heats the preheated first material again, energy consumption is lower, and heating efficiency is higher.
