Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging forming heat shrinking machine. Background Art

[0002] Fresh products are generally packaged in heat shrink bags. The products are placed in heat shrink bags, which are heated to shrink and wrap the products tightly, fully displaying the appearance of the items, improving the product's sales, and increasing its beauty and value. At the same time, it can also extend the shelf life of fresh products, achieve large-scale circulation of fresh products, and improve the industry structure. When fresh processed products (such as meat slices and shrimps) are placed in heat shrink bags, they may be concentrated in one place in the bag, resulting in uneven filling of the heat shrink bag.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0023] In the embodiment, Figure 1 , Figure 2 , Figure 3As shown, the packaging forming heat shrink machine includes a frame 1 and a No. 1 conveyor belt 2 arranged at the front end of the frame 1, a No. 2 conveyor belt 3 and a hot water tank 4 are arranged in the frame 1, and the No. 2 conveyor belt 3 is a V-shaped structure, and also includes:

[0024] A first pressing wheel assembly 5 is arranged above the first conveyor belt 2, the distance between the first pressing wheel assembly 5 and the first conveyor belt 2 is adjustable, and the first pressing wheel assembly 5 gradually tilts downward toward the direction close to the frame 1;

[0025] The second pressure wheel assembly 6 is arranged on both sides of the first conveyor belt 6. The second pressure wheel assembly 6 is located below the first pressure wheel assembly 5. The distance between the second pressure wheel assembly 6 is adjustable.

[0026] The heat shrink bag containing the product is gradually flattened along the No. 1 pressure wheel assembly 5, and at the same time the No. 2 pressure wheel assembly 6 limits the left and right sides of the heat shrink bag to ensure that the products are evenly distributed in the heat shrink bag; by adjusting the height of the No. 1 pressure wheel assembly 5 and the width between the No. 2 pressure wheel assembly 6, the products in the heat shrink bags of different sizes can be evenly distributed, thereby ensuring that the heat shrink bag shrinks and remains flat.

[0027] In the embodiment, Figure 1 , Figure 2 As shown, the No. 1 pressure wheel assembly 5 includes a No. 1 pressure wheel seat 51 and a No. 1 pressure wheel 52. The No. 1 conveyor belt 2 is provided with a connecting frame 7. The No. 1 pressure wheel seat 51 is connected to a No. 1 threaded rod 8 for matching with the connecting frame 7. The other end of the No. 1 threaded rod 8 is connected to a hand wheel 9. The No. 1 threaded rod 8 and the connecting frame 7 are threadedly matched. The No. 1 pressure wheel seat 51 is adjusted to move up and down by turning the hand wheel 9, thereby adjusting the distance between the No. 1 pressure wheel assembly 5 and the No. 1 conveyor belt 2, and the adjustment is convenient.

[0028] In the embodiment, Figure 2 As shown, the No. 1 pressure roller seat 51 is provided with a fixing block 10 for connecting with the No. 1 threaded rod 8, and the side of the connecting frame 7 is provided with a waist hole 11, and the bolt passes through the waist hole 11 to connect with the fixing block 10. When the height of the No. 1 pressure roller assembly 5 is adjusted, the No. 1 pressure roller seat 51 is locked by bolts to prevent the No. 1 pressure roller seat 51 from moving easily.

[0029] In the embodiment, Figure 5 As shown, the outer wall of the No. 1 roller 52 is provided with a dustproof coating 12. Ensure that the surface of the No. 1 roller 52 is clean and tidy to prevent contamination of the surface of the heat shrink bag.

[0030] In the embodiment, Figure 3 , Figure 4 As shown, the distance between the feeding ends of the left and right second pressing wheel assemblies 6 gradually decreases along the feeding direction. The distance between the feeding ends of the left and right second pressing wheel assemblies 6 is large, which is convenient for the packaging bag to enter.

[0031] In the embodiment, Figure 3 , Figure 4 As shown, the second pressure wheel assembly 6 includes a second pressure wheel seat 61 and a second pressure wheel 62, and mounting plates 13 are provided on both sides of the first conveyor belt 2. The outer side of the second pressure wheel seat 61 is provided with a second threaded rod 63 that passes through the mounting plate 13, and the two sides of the mounting plate 13 are provided with adjustment nuts 64 for cooperating with the second threaded rod 63. By adjusting the adjustment nuts 64 provided on the left and right sides of the mounting plate 13, the second threaded rod 63 can be moved left and right, thereby adjusting the spacing between the second pressure wheel assemblies 6, and the adjustment is convenient.

[0032] In the embodiment, Figure 1 As shown, a blowing mechanism is provided at the discharge end of the frame 1, and the blowing mechanism includes an air compressor 14 and a blowing pipe 15. The heat shrink bag is cooled to facilitate workers to take and pack.
