Abstract

The invention relates to commercial machinery, equipment for the food industry and can be used for packaging in plastic bags of bulk products. The purpose of the invention is to increase reliability in operation and simplify the design. A device for making, filling and sealing packages of a thermo-adhesive material comprises a sleeve former 1, a pipe 2, rollers 3 and 4 for feeding a film, a device 5 for forming a longitudinal seam, a device for forming transverse seams and a drive. The device for forming transverse seams includes two welding jaws 6 and 7 with heating elements 8, mounted on levers 9 and 10, having longitudinal grooves 11 and 12, and a plate 13 with rollers 14 and 15. A spring-loaded valve 17 is fixed on each lever under a longitudinal groove The drive contains a disk 19, a crank 20, a double-arm lever 21, a slider 22 located on a vertical rod 23, t gu 24, a chain drive 25, a ratchet mechanism 26 connected to the roller 3. The roller stop 27 interacts with the bar 28 and through a lever system - with adaptation 5. Rollers 14 and 15, when the opened arms 9 and 10 move upward, freely pass through the grooves 11 and 12, depress the valves 17, and when the downward movement of the levers, the rollers act on the valves and reduce the levers 9 and 10 until the jaws 6 and 7 are closed. 2 Il.
