The invention discloses an automatic seasoning packaging machine and a packaging method, and relates to the technical field of packaging machines, and the packaging machine comprises a rack, a feeding barrel, a discharging pipe, a side edge heat sealing mechanism, an end heat sealing mechanism, a cleaning and powder removing mechanism and a knocking mechanism. According to the cleaning and powder removing mechanism, a second motor drives a piston to do reciprocating motion in a connecting cylinder, and airflow circulation is formed; when the piston moves upwards, dust-containing air is sucked in from the packaging bag through a communicating assembly; when the piston moves downwards, air is pressed into the filtering ring cavity to be filtered, and after static electricity is eliminated through the static electricity eliminator, the air can be sprayed out from the rotating cylinder which swings at multiple angles through guiding of the fixed cylinder and the folding pipe to purge the bag wall. The deflection assembly moves along with the piston to drive the folding pipe and the rotating cylinder to swing back and forth to slightly knock the bag wall. The knocking mechanism knocks the outer wall of the discharging pipe to shake off accumulated powder. After filling, the inner wall of a packaging bag and a discharging pipe are automatically and efficiently cleaned, the sealing performance of a seal is remarkably improved, material waste and pollution are reduced, and high-quality, automatic and continuous packaging of seasoning powder is achieved.

This utility model relates to a coating equipment suitable for copper-clad laminate production, comprising: a cleaning component including a dust collection box, wherein two dust collection rollers are symmetrically arranged inside the dust collection box, the dust collection rollers are connected to a drive motor, and multiple brushes are evenly distributed on the outer periphery of the dust collection rollers; a coating impregnation box, wherein an inlet is provided on one side of the coating impregnation box, and an outlet and a return outlet are provided on the other side, the inlet being connected to a second opening, and multiple guide rollers are provided inside the coating impregnation box; a coating scraping component including a transfer box, wherein the transfer box is connected to the interior of the coating impregnation box through the outlet and the return outlet, a connection port is provided on the side of the transfer box away from the coating impregnation box, two scrapers are symmetrically arranged inside the transfer box, and an inclined guide plate is provided at the bottom of the transfer box; and an oven, wherein the inlet of the oven is connected to the connection port. This coating equipment can effectively save production costs and improve production quality.

The utility model relates to the technical field of self-suction door lock emergency interruption devices, in particular to an electromagnetic control type self-suction door lock emergency interruption device. According to the technical scheme, the emergency switch comprises a machine shell, an electromagnet fixedly installed in the machine shell, an armature attracted to the electromagnet, an emergency button for manually powering off the electromagnet, a reset spring for driving the emergency button to reset under the action of elastic force, and a slow return assembly installed in the machine shell. The slow return assembly ensures that the reset spring rapidly contracts and reduces the elastic force release speed of the reset spring. Manual reset is not needed, the door plate which is not completely pulled open by a distance can be effectively prevented from being adsorbed again, the problem that the door cannot be effectively opened is avoided, and the risk of clamping injury is prevented.

The utility model provides a kind of lining stainless steel pipe processing device, including base, the base is equipped with several for placing carbon steel pipe's rack, the one end of the base is equipped with several dust-removing frame, the dust-removing frame hollow near upper end, the hollow is equipped with several soft rubber block, the soft rubber block is fixed in the inner wall of hollow, and the dust-removing brush is equipped in the soft rubber block top.The utility model provides a kind of lining stainless steel pipe processing device, by setting dust-removing frame before rack, when inserting stainless steel pipe into carbon steel pipe, stainless steel pipe first passes through several dust-removing frame, and the dust-removing brush on dust-removing frame sweeps away dust and other impurities on the surface of stainless steel pipe, to prevent electrostatic adsorption of dust again in sweeping process, grounding device effectively removes static electricity, prevents the re-adsorption of dust impurities, so that carbon steel pipe and stainless steel pipe are better in the subsequent hydraulic composite combination strength and uniformity.
