Abstract

Compact forming, filling and sealing machine for producing sealed cup-shaped containers. And other structures of sealed containers This includes a flowable product distribution container with a scratch line over the total stress overhang.

Claims (5)

1. A machine for the production of a pre-configured number of pre-filled and sealed containers at the same time and automatically, as well as a pneumatically driven adjustable conveying device to drive the main shaft. A gear wheel is attached to the main shaft to fix and allow a pair of roller chains that carry the plastic sheet to move forward at intervals. And a break in accordance with the movement of the main shaft The roller chains used to convey the plastic sheet include a number of upright protrusions. A cylinder with a rotating overhang is driven by such a roller chain. Rollers for conveying the bottom plastic sheet that can be thermoformed from the transfer roller to the axial cylinder. The cylinder with the axle thrusts each opposite side edge of the bottom plastic plate into the overhang of the roller chain. Equipment for the underside of the plastic sheet intermittently to the heating station. The plastic sheets are then heated until they can be molded by heat. A device for intermittent conveying of hot plastic sheets to the forming station. The forming station includes a retractable mold for forming a number of cup-like basins in the plastic underneath it. A device for conveying the molded bottom sheet to the filling station. The filling station includes a filling device for packing equal quantities of product that is delivered to the filling station in each such cup-like basin. Driven rollers for intermittent forwarding of the thermoformed top plastic sheet. In chronological order with intermittent forward movements For forming and packing of plastic sheets below The driven rollers for the upper sheet convey the top plastic sheet closer to the And parallel to the bottom of the plastic sheet after the cup-shaped basins were filled. Equipment for conveying the plastic sheet as below And the above plastic sheet together from time to time To the sealing station The sealing station includes Movable hot sealing mold And a clamping device for heat sealing the top and bottom plastic panels. Intermittent top and bottom transport of plastic sheets To the clocking station The station includes A number of hammer-out dies, which hammer the rounded holes in the sealed plastic sheet at the corners of each container to be molded. Intermittent feeding and retrieval of sealed top and bottom plastic sheets To the longitudinal cutting station Where the cutting knife cuts the above and below plastic sheets along the opposite sides of the cup-shaped basins and near the protrusions that hold the edge of the bottom plastic sheet. Make a diagonal cut to cut the above and below plastic sheets along the two opposite sides of the cup-shaped basins. To separate the finished containers from each other A device for transporting the said container from the machine Ejection roller to remove the bottom plastic plate edge from the roller chain protrusion. 2. The machine according to claim 1 includes solid-state programmable control devices. For controlling the propulsion equipment used in such conveyors 3. Machine according to claim 1, where the forming device includes a vacuum device for sucking the plastic sheet below into the female mold plate and air pressure device for pressing. Press the plastic sheet at the same time into the forming mold. 4. The machine according to claim 1, where the driven roller for the above plastic sheet conveying, includes a differential drive roller and a fixed drive roller, and includes a notch device for making the top plastic sheet. Notched with a partial protrusion through the thickness of the plastic sheet. Such differential and static drive rollers are used for conveying the above welded plastic sheets. Through heating and forming devices that produce total stress Forming devices causing such combined stress Is used to create a protrusion in the above plastic sheet where the scratch line is raised. This will cause the indentation to go away from the surface of the plastic sheet and the alignment measuring device for detecting mismatch between the top plastic sheet and shaped basins. The cup is in the plastic plate below. The measuring devices include devices for transmitting control signals to different actuators to correct misalignment. 5. Machine according to claim 1, where a filling station for filling the product that can flow into a cup-like basin in a plastic sheet below the said filling station includes a filling stick consisting of: A number of product outlets are positioned with each cup-like basin in the bottom plastic plate. Each product outlet is connected to the expandable diaphragm chamber and includes a valve to close the contact. The product inlet is connected to each of the expansion diaphragm chambers. A device for bringing the product to each such chamber under pressure A device for blocking the pressure exerted on such products. When each of these chambers is fully filled and a device to close the connection between each chamber and the outlet of the said product, when the product is loaded into the chamber and the piston set for the diaphragm collapse. Down when the product output from the outlet of that product fills each such room.
