The elastic plug is arranged at the end part of the rotatable roller in a sleeving manner, and the elastic plug is positioned in the accommodating cavity; the covering part is arranged at the end of the rotatable roller in a sleeving mode, the covering part covers the containing cavity and is connected with the shell, and the side, facing the elastic plug, of the covering part abuts against the elastic plug.

This utility model discloses a mouse feed mixing device that is easy to disassemble and clean. It includes a mixing cylinder with a cover at the top and a discharge hopper at the bottom. The upper and lower sides of the cylinder are connected by fixing components. A mixing motor is installed at the center of the top of the cover, and a mixing rod is connected to the bottom of the motor. A feed hopper is installed on one side. The fixing components include multiple fixing blocks on the upper and lower outer walls of the cylinder. The bottom of the blocks has a telescopic groove with a locking block inside. The bottom of the groove has a through hole. One end of the locking block has a connecting rod with a matching through hole. A ball is fixed at the end of the rod. The upper and lower locking blocks respectively fix the top of the cover and the edge of the discharge hopper. After the discharge hopper is removed, the inner wall and the discharge pipe are unobstructed, so it can be directly rinsed or soaked for disinfection. The upper and lower outer walls of the cylinder are equipped with sealing rings. When the cover and the discharge hopper are installed, they fit snugly with the sealing rings to prevent feed powder leakage and powder seepage into the gaps. With the help of the telescopic locking block and the elastic force of the compression spring in the fixing block, the cover, the discharge hopper and the cylinder can be quickly fixed. When disassembling, the ball is pressed.

The utility model relates to packing box technical field, specifically disclose a powder bag packing box with multi -chamber, including packing box, the outside fixed mounting of packing box has the fixed frame, the side surface of packing box is provided with the metal sheet, the top of fixed frame is provided with second cover frame, the side surface of second cover frame is provided with first cover frame, the inside fixed mounting of packing box has the bearing frame, the side surface of first cover frame is provided with two sealed location components, the top of second cover frame is provided with a plurality of fixed anti -touching component, this powder bag packing box with multi -chamber, first cover frame provides basic fixed force through magnetic attraction piece, and further restricts displacement in cooperation with the limiting rod with rubber sleeve, and the fixed effect is more reliable, and the abrasion of limiting rod and through -hole can be reduced with rubber sleeve, prolongs the life of component and enhances friction limit, and the sealing ring of protection ring closely fits with the recess, can effectively realize sealing, prevents the powder bag in chamber from being damp or powder leakage.

This invention discloses a feeding device and method for metal powder rolling, relating to the field of metal powder rolling equipment. The device includes a feeding hopper with a discharge port at its bottom. Movable side plates of the feeding hopper are slidably connected to a front and rear end plate. A gap adjustment mechanism is installed on the feeding hopper to adjust the position of the movable side plates and change the size of the discharge port. Two sets of stirring shafts are installed inside the feeding hopper, with follower wheels connected to the ends of the stirring shafts for frictional contact with the rolling mill rolls. An adjustable partition mechanism is also installed inside the feeding hopper between the two sets of stirring shafts. Based on this device, the method uses the gap adjustment mechanism in conjunction with a replaceable nozzle insert to synchronously adjust the discharge port size with the roll gap. The angle of the partition is adjusted by the swing adjustment mechanism to control the composite layer thickness ratio, and the rollers drive the follower wheels to rotate the stirring shafts. This invention can improve feeding uniformity, adapt to different roll gap specifications, and achieve precise layer control of composite materials.

The utility model relates to the technical field of selenium drums, in particular to a selenium drum with a small magnetic roller, which comprises a selenium drum shell, a side cover is mounted on the surface of the selenium drum shell, a gear set is arranged in the side cover, and a cost-saving mechanism is arranged on the surface of a magnetic roller body and the inner wall of the gear set. A convenient replacement mechanism is arranged on the surface of the powder scraping knife and the inner wall of the toner cartridge shell, and a powder leakage prevention mechanism is arranged on the surface of the powder outlet. According to the toner cartridge, the cost of a user is saved when the toner cartridge is used, the use requirement of the user can be better met when the toner cartridge is used, the user can conveniently take down the powder scraping knife from the interior of the toner cartridge shell and replace the powder scraping knife when the toner cartridge is used, the cleaning effect of the toner cartridge on redundant carbon powder on the surface of the magnetic roller body is better, and the use effect of the toner cartridge is improved. In addition, when the selenium drum is used, a user can conveniently clean out waste powder in the waste powder bin, and the phenomenon of powder leakage in the use process of the selenium drum is avoided.
