A dual-temperature heating sealer relates to the improvement of the structure of an electrothermal sealer for sealing a plastic bag of a liquid flexible packaging machine. On the side plane (8) of the hot press seat (1) of the present invention, a groove (7) with a semi-circular section is axially opened, and the side plane (8) and the groove (7) on the side of the hot press seat (1) are formed. An insulating layer (3) is provided inside, and the heating wire (4) is fixed in the groove (7) provided with the insulating layer (3), and the sealing briquette (5) for back-and-forth movement of the pressure-sealed plastic bag is provided Heat the side of the seat (1). The utility model has two sealing opportunities at the time of sealing, one time is hot pressing sealing, and the other is electric heating wire sealing, which solves the problem of unstable quality when the electric heating type and current pulse heating type sealing device is sealed and solves the problem of heat The sealing and cutting of the cold-press-type sealer is completed twice, and the problem of the plastic packaging bag less than 10 μm in thickness cannot be sealed. The utility model has the advantages of simple structure, good sealing effect, simultaneous sealing and cutting off, and stable and reliable sealing quality.
The L-Shaped Adjustable Desk is one of the height adjustable desks. Compared with the ordinary height adjustable tables, the L-Shaped is more stable and firm. L-Shaped has bigger usable floor area, can pile more things. Since the L-Shaped is driven by three motors, it has better load-bearing capacity and lifting capacity than the normal model.
Our L-shaped top is made up of two rectangular pieces, so it can be assembled in either a right or left facing configuration.L-Shape Standing Desks, L-Shape Office Desk, Height Adjustable Standing Desk
