Semiautomatic bottom sealing device of plastic bottom-folded bag

Abstract

The invention relates to a semiautomatic bottom sealing device of a plastic bottom-folded bag, and relates to the technical field of packaging bag manufacturing devices. The semiautomatic bottom sealing device comprises a machine frame, a supporting mold, a hot-press mold and a driving mechanism. At least one supporting mold is movably installed on the machine frame. The driving mechanism is alsoinstalled on the machine frame. The driving mechanism drives the hot-press mold to rise or fall. When the supporting mold is located on a sleeving station, the supporting mold is manually sleeved withthe plastic bottom-folded bag. When the supporting mold moves to a hot-press station, the bottom of the plastic bottom-folded bag is just driven by the supporting mold to the place under the hot-pressure mold. When the hot-press mold falls to the lowest position, the bottom of the plastic bottom-folded bag is attached through pressing and heating. The semiautomatic bottom sealing device has the advantages of being stable in structure, improving the bottom sealing efficiency of the plastic bottom-folded bag, and being convenient and safe to operate.

Description

technical field

[0001] The invention relates to the technical field of packaging bag making equipment, in particular to a semi-automatic bottom sealing equipment for plastic folding bottom bags. Background technique

[0002] Folding bottom bag is a common packaging bag on the market at present. It is mainly made of paper and plastic. The folding bottom bag itself is made of a rectangular material, and then the bottom of the folding bottom bag is glued. seal to form figure 1 In the semi-finished product 101, the semi-finished product 101 is combined with the crease (shown by the dotted line), and then processed and formed on the bottom of the semi-finished product 101. When the material of the folded bottom bag is paper, it is sealed and bonded by glue), so that figure 1 Finished product 102 in .

[0003] At present, the process of processing the above-mentioned semi-finished product 101 into the finished product 102 is basically done manually, and the specific operations ...

Examples

Embodiment 1

[0042] refer to figure 2 , is a semi-automatic bottom sealing device for plastic folding bottom bags disclosed in the present invention, comprising: a frame 1, a supporting mold 2, a hot pressing mold 3 and a driving mechanism 4.

[0043] There are two supporting molds 2 movable on the frame 1, and the driving mechanism 4 is also installed on the frame 1. The driving mechanism 4 drives the hot-pressing mold 3 to lift; The bag cover is placed on the support mold 2. When the support mold 2 moves to the hot pressing station, the bottom of the plastic folding bottom bag cover is just driven by the support mold 2 to directly below the hot pressing mold 3. When the hot pressing mold 3 falls to the lowest position, it passes Pressing and heating make the bottom of the plastic fold-bottom bag cover stick.

[0044] The supporting mold 2, the hot pressing mold 3, and the driving mechanism 4 are provided with 2 sets and are respectively arranged on different sides of the frame 1. In ot...

Embodiment 2

[0057] refer to Figure 5 and Figure 6 , is a semi-automatic bottom sealing device for plastic folding bottom bags disclosed in the present invention. The difference from Embodiment 1 is that the inner side wall of the frame 1 is provided with a chute rail 14, and the bottom side of the support mold 2 is provided with a sliding rod 25. The end of the sliding rod 25 away from the supporting mold 2 is horizontally slidably assembled with the chute rail 14, and a pulley 26 is arranged between the end of the sliding rod 25 and the chute rail 14. to move horizontally.

[0058] The chute rail 14, the sliding rod 25 and the pulley 26 cooperate with each other, so that the support mold 2 can be horizontally slid and assembled on the frame 1. When the support mold 2 is covered with a plastic folding bottom bag, the support mold 2 should be slid to the outside of the frame 1 That’s it (at the set-up station), and then push the supporting mold 2 inside the frame 1 until the supporting...
