Three-edge-sealing bag-making device for food packaging

[0022] A three-side sealing bag-making device for food packaging, located between the conveyor belt 6 and the middle-sealing film-stretching station, and comprising a horizontally arranged bag maker forming tube 1 and a bag maker garment welded to the bag maker forming tube 1 The collar 2 and the bag maker fixing plate 3 for fixing the collar 2 of the bag maker, in which:

[0023] The bag maker forming tube 1 is a trough tube with side openings. One end of the bag maker forming tube corresponds to the film drawing roller set 41 vertically arranged in the middle sealing film drawing station, and the other end is an inclined inlet 11 ;

[0024] The bag maker collar 2 is formed by bending a flat plate 5 with a triangular opening 51 on one side, and one end is formed with an oblique outlet to facilitate welding and fixing with the oblique inlet 11 of the bag maker forming tube 1, and the other end is connected with The vertical bag maker fixing plate 3 is fixed to facilitate the introduction of the packaging film.

[0025] The conveyor belt 6 is composed of multiple sets of belts 61 driven by a motor side by side, and corresponds to the inclined inlet 11 on the forming tube of the bag maker. The multiple sets of belts are staggered and arranged to form a beveled edge 62 to facilitate the delivery of products on the conveyor belt 6 Enter the inclined inlet 11 of the forming tube 1 of the bag maker.

[0026] The film pulling roller set 41 is driven by the driving roller 42 and clamps the packaging film of the wrapped product to move, so as to realize the middle sealing and pulling film.

[0027] The working principle of the present invention is:

[0028] The bag maker collar 2 is made of image 3 The illustrated flat plate 5 with a triangular opening 51 on one side is bent, and welded together with the oblique outlet 11 at one end of the forming tube 1 of the bag maker, the collar of the bag maker 2, the forming tube 1 of the bag maker The three-side sealing bag-making device is formed with the bag-making device fixing plate 3, and the cross-section of the packaging film becomes an oval shape after passing through the three-side sealing bag-making device, forming the prototype of the three-side sealing of the packaging film. In the middle sealing film pulling station, the film pulling drive drives the vertically placed film pulling roller group 41 to rotate. The film pulling roller group 41 pulls the packaging film forward. The speed of the film pulling roller group 41 can be adjusted to change the packaging film through three sides. The tightness when sealing the bag making device, so that the packaging bag is easier to form and the packaging effect is better. In order to cooperate with the three-side sealing bag-making device, the product transition belt 61 is composed of four belts. Each belt has a different length, forming the same angle as the three-side sealing bag-making device, so that the product can smoothly enter the three-side belt through the product transition belt 61 Inside the side sealing bag maker. The packaging film enters the film drawing roller group 41 through the forming tube 1 of the three-side sealing bag maker. At this time, the packaging film and the product figure 1 Shown. The film pulling roller group 41 closes the packaging film up and down and pulls it forward to pull the paper. At this time, the packaging bag is like figure 2 As shown, the packaging bag then enters the middle seal for side encapsulation, and finally enters the end seal encapsulation. The final packaging bag is such as image 3 Shown.
