Abstract

The invention discloses a heating mechanism for a product packaging thermal shrinkage film. The heating mechanism comprises a frame seat, a mounting plate, a feeding hole, a discharging hole, a top plate, a circulating heating assembly, a cylinder seat, a fan, a filter screen sheet, a detection control main body, a power line and a control switch. According to the heating mechanism, the circulating heating assembly is arranged through optimization, and a servo motor serves as a power source; through cooperation of a driving gear and a driven gear ring, a fixing rod drives a support to be adjusted and changed in the height position in the vertical direction, so that an air port is aligned with a product according to the size and shape of the product, and meanwhile a driving motor serves asa power source to enable a transmission belt to rotate through rotation of a belt wheel; and the transmission belt drives a connecting block to transversely move in a rectangular groove, so that the horizontal position of hot air discharged from the air port is changed, heat treatment can be conducted according to the size of a product, and the guaranteed efficiency and packaging quality of the product are guaranteed.

Description

technical field

[0001] The invention relates to the related field of product packaging, in particular to a heating mechanism for heat shrinkable film of product packaging. Background technique

[0002] Heat shrinkable packaging is one of the more advanced packaging methods in the market. It uses shrink film to wrap the outside of the product or package. After heating, the shrink film wraps the product or package tightly, fully displaying the appearance of the item, improving the product's displayability, increasing the appearance and Sense of value; the heat-shrinkable film packaging equipment used for product production is equipped with a heating mechanism inside, which is used to heat the heat-shrinkable film to shrink it.

[0003] The heating mechanism for heat-shrinkable films in the prior art has a simple structure. By directly using hot air for heat treatment, when heat-treating products of different sizes and shapes, it is inconvenient to bring the hot air close to th...

Examples

Embodiment 1

[0030] see figure 1 and figure 2 , a heating mechanism for product packaging heat shrinkable film of the present invention, comprising a frame seat 1, a mounting plate 2, a feed port 3, a discharge port 4, a top plate 5, a circulation heating assembly 6, a cylinder seat 7, a fan 8, a filter Mesh 9, detection and control main body 10, power cord 11 and control switch 12, mounting plate 2 is fixedly connected to the bottom of the front and rear sides of the frame base 1, and the bottom of the left and right sides of the frame base 1 is respectively provided with a material inlet 3 and a material outlet 4 , the top plate 5 is embedded in the inner top side of the frame seat 1, the top middle side of the top plate 5 is vertically fixed with a cylinder base 7, the inner middle side of the cylinder base 7 is fixedly connected with a fan 8 by bolts, and the inner top side of the cylinder base 7 is embedded with a filter mesh 9. The detection and control body 10 is fixedly connected...

Embodiment 2

[0035] In a heating mechanism for product packaging heat shrinkable film of the present invention, the structure size of the upper roller 662 and the lower roller 663 are the same, and there are two upper rollers 662 and lower rollers 663, so that the transmission belt 664 can be easily Support transmission, the number of air ports 682 is not less than eight, and the air ports 682 are equidistantly distributed on the inner end surface of the outer frame 681, which is conducive to blowing hot air to the surface of the heat shrinkable film. The outer frame 681 is arch-shaped and hollow inside, and the electric heating Both the pipe 683 and the hose 684 are arranged symmetrically front and back in the middle side of the outer frame 681, which is conducive to fully heat-treating the heat-shrinkable film. The top surface of the transmission belt 664 is provided with a limit piece, and the left and right sides of the limit piece are inserted into the outer sleeve 6774 The inner wall ...
