Integral lifting heat-seal mold device

Abstract

The invention discloses an integral lifting heat-seal mold device. The device comprises a heat-seal upper mold, a heat-seal lower mold and a heat-seal supporting plate, wherein guide columns are arranged at four corners of the heat-seal upper mold and are sleeved with heat-seal supporting plate; the heat-seal lower mold is arranged at the upper end face of the heat-seal supporting plate; a heat-seal lifting cylinder mounting plate is arranged under the heat-seal supporting plate; the heat-seal supporting plate is pushed by a drive device which is arranged on the heat-seal lifting cylinder mounting cylinder; the lower end face of the heat-seal lifting cylinder mounting plate is fixedly connected with a heat-seal middle guide plate, and the heat-seal middle guide plate is fixedly connected with the guide columns; a cylinder is fixed on the heat-seal guide plate; the piston end of the cylinder is connected with a heat-seal lifting bottom plate; a short shaft is arranged on the heat-seal lifting bottom plate; and the heat-seal middle guide plate is arranged on the short shaft in a slide sleeving manner. The device can be used for performing heat-seal on one-side convex package material and two-side convex package material, and has the advantages of wide application range, simple structure, easiness in manufacture and maintenance and long service life.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to an integral lifting heat-sealing mold device. Background technique [0002] At present, in the stretch film automatic packaging machine, after the material is loaded into the packaging film, it needs to be heat-sealed to complete the sealed packaging of the material to protect the material. The upper mold of the heat-sealing mold device in the prior art is usually It is fixed, and the lower mold can move up and down, so in heat sealing such as Figure 4 For the single-sided convex package shown, since the upward side of the package is flat, it is no problem to complete the heat sealing. The heat-sealed package can be demoulded smoothly after the lower mold is moved down, and it will be released in the transmission mechanism. Under the action, it will be transferred to the rear station, and the unheat-sealed package can also smoothly enter the heat-sealing mold for the...

Problems solved by technology

[0002] At present, in the stretch film automatic packaging machine, after the material is loaded into the packaging film, it needs to be heat-sealed to complete the sealed packaging of the material to protect the material. The upper mold of the heat-sealing mold device in the prior art is usually It is fixed, and the lower mold can move up and down, so in heat sealing such as Figure 4 For the single-sided downward convex package shown, since the upward side of the package is flat, it is no problem to complete the heat sealing. The heat-sealed package can be demoulded smoothly after the lower mold is moved down, and it will be released in the transmission mechanism. Under the action, it will be transferred to the rear station, and the unheat-sealed package can also smoothly enter the heat-sealing mold for the next heat-sealing, but in case of Figure 5 For the double-sided convex package shown, since the upward side of this type of package is also convex, and the upper mold of the heat-sealing device is not moving, the gap between the lower surface and the package is not large, and the package It is impossible to enter the heat-sealing mold station, so the heat-sealing work cannot be completed. Therefore, the applicable range of the existing heat-sealing mold structure is small, so that the applicable range of the whole machine is also small, which is a problem that needs to be improved.
