Description

Vacuumizing heat sealing equipment Technical Field The utility model relates to the technical field of toy packaging, in particular to vacuumizing heat-sealing equipment. Background At present, a plurality of packaged small toys, such as twisted eggs, small toy balls, small injection molding pieces and the like, in the toy production process, because the single volume of the small toys is relatively small, if each small toy is packaged independently, the small toys are very troublesome to transport and increase the cost, meanwhile, the small toys can be sold directly in the selling process without packaging or secondary packaging, and manufacturers generally put the small toys into a packaging bag uniformly and then put the packaging bag into a paper box, so that the waterproof and dustproof effects can be realized, and the protection performance is improved. At present, after the small toy is placed in the packaging bag, the packaging bag is required to be vacuumized and heat-sealed, and all toys in the packaging bag are extruded together by utilizing the atmospheric pressure, so that the situation that excessive movable gaps exist among all toys in the packaging bag can be effectively ensured, and the packaging bag is favorable for later transportation. Except that the work of vacuumizing and heat-sealing the packaging bag is carried out manually and sequentially and the handheld heat-sealing clamping plate is adopted for heat-sealing, in order to improve the efficiency of the work and ensure the heat-sealing quality in the current industry, the semi-automatic vacuumizing heat-sealing equipment is generally adopted for solving the problems. For example, patent CN202411085935.4, a sealing machine for ton bag package, in which, when the bag mouth is in a fully opened state, the clamping frame rotates through the connecting rod, so that two sponges press and attach the bag mouth, at this time, the air extraction component extracts the air in the bag, after the air in the ton bag is extracted, the air extraction component gradually rises until the air leaves the ton bag, the clamping frame continuously pushes the heating resistor layers on two sides towards the control box until the heating resistor layers on two sides are abutted against two sides of the bag mouth through the rotation of the connecting rod, so as to drive the heating resistor layers to work, at this time, the rapid thermoplastic sealing of the bag mouth can be completed. However, in the patent, after the bag mouth is smoothed out, the worker can clamp the bag mouth through the clamping frame for heat sealing, if the worker does not smooth out the bag mouth, the overlapping area of the bag mouth may have air leakage in the normal heat sealing process, and if the heating time is increased to ensure the heat sealing effect of the overlapping area, the bag mouth in the normal area is easily melted due to the overlong heating time, and the heat sealing effect cannot be ensured. Disclosure of utility model In order to overcome one of the defects in the prior art, the utility model aims to provide the vacuumizing heat-sealing equipment, which can not only vacuumize and heat-seal, but also smooth the bag opening before heat sealing and ensure the heat-sealing quality.
