The paper feeding and discharging mechanism set inside automatic paper feeding device includes a driver, rollers, gears and a one-way unit. After canceling paper feeding, the inversely rotating driver is matched with the gears and the one-way unit to make at least one of the rollers approaching the paper discharging position continue rotating in the paper discharging direction and the paper be discharged automatically without damage.

The invention discloses a forming die for a large hoop, and relates to the technical field of dies. The forming die comprises an upper die and a lower die; the section of the upper die is in a U shape, and the width is gradually increased from top to bottom; the lower die comprises a fixed block; the fixed block is rotatably connected with two L-shaped modules; the two L-shaped modules are oppositely arranged, and fit the side surface of the upper die; the upper die comprises a wedge block; pin shafts are fixed to the upper surface of the wedge block side by side; the upper ends of the pin shafts penetrate through an upper padding plate, and springs sleeve the upper ends of the pin shafts; two side surfaces of the wedge block are slidably connected with side modules; bending blocks are fixed to the upper ends of the side modules; and the upper surfaces of the bending blocks are slidably connected with the lower surface of the upper padding plate. By arranging the two L-shaped modules,through pressing of the upper die, the L-shaped modules are used for laterally extruding the hoop, and the problem that the production efficiency is affected due to low adaptability of an existing lowdie is solved; and the upper die is arranged as the wedge block and the two-side modules, and the problems that an existing hoop is required to be taken down manually after being formed, and the production efficiency is low are solved.

The invention relates to a hydrofluoric acid liquid transfer device and a transfer method. The device comprises a reciprocating conveying mechanism, a storage box, and a box taking mechanism, whereinthe storage box is used for loading hydrofluoric acid liquid, is borne on the reciprocating conveying device, and is driven to move by the reciprocating conveying device; the box taking mechanism takes down the storage box from the conveying tail end of the reciprocating conveying mechanism; the reciprocating conveying mechanism comprises a driving chain wheel arranged at the conveying initial end, a driven chain wheel arranged at the conveying tail end, and chains sleeving the driving chain wheel and the driven chain wheel; the chains comprise pin shafts, and links connected with all the pinshafts from two ends of the pin shafts; and two ends of the pin shafts extend out, and are fixedly sleeved with link blocks. The device needs no manual intervention in the transfer process, can monitor if hydrofluoric acid in the storage box is leaked in the transfer process, is provided with double layers of seals for effectively preventing leakage of the hydrofluoric acid liquid to the terminal,and solves the defect of possible damage of workers in traditional transfer of the hydrofluoric acid.

A device for helically cutting and automatically removing waste sheathing from the stressing tails of unbonded tendons. The device comprises an elongated body and an attached cutting head. Both the body and the cutting head have a uniform through bore along their longitudinal axis for accepting a post-tensioned tendon. The cutting head comprises an integral blade having a cutting face radially offset from the longitudinal axis and inclined at a pitch angle of between 45 and 85 degrees relative to the longitudinal axis. The blade cuts the sheathing while also ejecting the waste sheathing.

The invention discloses a polystyrene vacuum automatic packaging forming machine, which belongs to the technical field of vacuum packaging. The polystyrene vacuum automatic packaging molding machine includes a box body, an air pump, and a heat-press sealing machine. The box body is provided with a vacuum chamber. The air cylinder and the air pump are connected through a second connecting pipe, a piston plate is slidably connected in the air cylinder, and a connecting plate is fixedly connected to the lower end of the piston plate, and the connecting plate is slidably connected to the air cylinder and the box body, and the heat-press sealing The machine is connected to the bottom end of the connection plate, and the transmission and placement plate is slidably connected in the box, and the transmission and placement plate is connected with the connection plate. This device can vacuum the polystyrene packaging bag while vacuuming the vacuum chamber. Sealing, and after the sealing is completed, the polystyrene packaging bag is automatically removed.

An electric dust collector is provided; an electric brush, which is internally mounted in a sucking device, is coated with a sheet to clean, such a structure is beneficial to expand uses of the electric dust collector. In order to coat the sheet (50) over circumference of a rotary brush (25), the rotary brush (25) can be rotated toward a stated direction at a stated rotating speed through a brushmotor (44). Besides, for the purpose of disassembling the sheet (50) coated on the rotary brush (25), the rotary brush (25) is enforced to perform the positive rotation and inverse rotation. Suction of the electric dust collector is enhanced to make use of the suction of an electric blower fan to automatically unlock the sheet. The invention can provide an electric dust collector which is able todisassemble the sheet (50) coated around the rotary brush (25) without the contact of user, and has excellent performance and great convenience.
