Description

Hot pressing carries sealing mechanism
Technical field
Packing technique is carried the present invention relates to one kind, more specifically, it relates to a kind of less hot pressing carrier band envelope of vibration Close mechanism.
Background technology
Conventional carrier band heat sealing mechanism is usually to be driven using cylinder at present, due to the unstability of pneumatic system, and The fluctuation that air pressure is produced, the peeling force for often leading to seal rear film cover strip is unstable, and fluctuation ratio is larger;Due to cylinder impact Presence, cause the noise during mechanism kinematic and shake all very big, produce noise pollution.
And much carrier band heat sealing mechanism is during operation, carrier band can be moved on guide rail with multiple directions, be had , easily there is the phenomenon that carrier band deviates guide rail in very big unstability.Seal effect of heat insulation between knife and other parts not good, from And causing other part temperatures too high, the temperature fluctuation on reduction of service life, and envelope knife is larger, it is impossible to accomplish accurate control System.
Chinese patent notification number CN201580577U, discloses a kind of belt stabilizing mechanism of loading of carrier band forming machine, includes One rail member, to guide the carrier band in continuous strip sheet along the carrier band linear sliding in own long axis direction, shape is opened with one Elongated sliding portion, with major axis of the major axis parallel to carrier band, and can allow by outside provide heat energy put in the cunning portion Carrier band a, limiting section abuts the major axis both sides with the carrier band, to limit and ensure linear shifting of the carrier band along own long axis direction It is dynamic;One first cooling end reduces the temperature of abutting portion of the limiting section to be connected to carrier band both sides, made on the rail member The temperature of carrier band major axis both sides side is maintained in a preset range, it is to avoid carrier band major axis both sides side is deformed because of overheat. This belt stabilizing mechanism of loading can ensure that carrier band moulding material is not influenceed by heat energy and produces the deformation missing such as warpage, to maintain into The quality of type product.But carry in heat seal process, noise and vibrations are larger, and easily occur carrying the phenomenon for deviateing guide rail, Seal effect of heat insulation between knife and other parts not good, and the temperature fluctuation sealed on knife is larger, it is impossible to accomplish accurate control.
The content of the invention
Instant invention overcomes existing carrier band heat sealing mechanism noise and shake larger, and carrier band easily occur and deviate guide rail Phenomenon, effect of heat insulation is not good between envelope knife and other parts, and the temperature fluctuation on envelope knife is larger, it is impossible to accomplish what is accurately controlled Not enough to carry in sealing mechanism, its course of work noise there is provided a kind of hot pressing and shake smaller, and it is inclined to be less prone to carrier band From the phenomenon of guide rail, the temperature fluctuation in good heat-insulation effect between envelope knife and other parts, and envelope knife is smaller, it is ensured that accurate control System.
