The application discloses a kind of plant fiber molded product transfer method and forming device, including frame, the top of the frame is fixedly connected with pulp pool, the two sides of the pulp pool are provided with grouting mouth, the inside of the pulp pool is provided with suction pulp mode.The application can improve the processing efficiency of plant fiber molded product, so that plant fiber molded product can automatically feed and discharge operation, and by setting surplus slurry storage tank, slurry can be prevented from excessive feeding, improve product processing qualified rate, telescopic cylinder and buckle can improve equipment connection stability, so that it can be recycled, buffer support rod and positioning drive device can support support net transition transfer positioning mode, prevent net transition transfer positioning mode from suffering excessive extrusion, cleaning rod and washing mold drive cylinder can automatically flush pulp pool, prevent slurry from sticking and accumulating, therefore, the application can automatically process product, product output efficiency is high and quality is good, and product can be continuously processed.

This utility model relates to the field of cement cover plate processing technology and discloses a quantitative feeding device for cement cover plate casting, including a feeding cylinder. A stirring device is installed inside the feeding cylinder, and a support frame is fixedly installed on the outer wall of the feeding cylinder. A discharge pipe is fixedly installed at the bottom of the feeding cylinder. This quantitative feeding device for cement cover plate casting, by starting a motor, causes the rotating shaft to drive the baffle plate to open. At this time, the extrusion rod does not extrude the T-shaped plate, and the extrusion spring resets the L-shaped rod and T-shaped plate, causing them to extrude the push rod, causing the sliding plate to block the bottom of the storage cylinder. Cement then enters the storage cylinder from the discharge pipe. When the baffle plate closes, the extrusion rod extrudes the T-shaped plate, and when it reaches the end, it extrudes the L-shaped inclined rod, causing the slider to rise. The reset spring then resets the sliding plate, opening the bottom of the storage cylinder. This achieves quantitative feeding, preventing over- or under-feeding.

The utility model provides a shell and tube type cooling device which comprises a main body mechanism and a leaking stoppage mechanism, the main body mechanism comprises a tubular condenser, a liquid outlet and a liquid inlet, the liquid outlet is formed in one side of the tubular condenser, and the liquid inlet is formed in one side of the bottom of the tubular condenser; the leaking stoppage mechanism comprises arc-shaped sleeves and an inclined hole plate, and the two arc-shaped sleeves are symmetrically arranged on one side of the tubular condenser in a sleeving mode; the tubular condenser is protected by arranging the arc-shaped sleeve, heat dissipation of the tubular condenser is facilitated through the heat dissipation holes in one side of the arc-shaped sleeve, the plugging part on one side of the arc-shaped sleeve is attached to the surface of the tubular condenser, and when the tubular condenser cracks, the two inclined hole plates are moved by rotating the screw rod, so that the inclined hole plates extrude the arc-shaped sleeve, and the tubular condenser is prevented from cracking. And the arc-shaped sleeve tightly holds the tubular condenser, so that emergency treatment can be performed on the tubular condenser through the plugging part of the arc-shaped sleeve, and crack expansion caused by untimely treatment is prevented.
