Problems solved by technology

[0003] At present, in the production process of biodegradable plastic bags, it is necessary to use a heat sealing device to heat seal the continuously formed garbage bags, separate the plastic bags into sections, and tear them for convenience. However, the existing heat sealing There are still some deficiencies in the device. During use, a high sealing pressure will directly cause the plastic bag to melt, while a small sealing pressure will lead to incomplete sealing and reduce the airtightness of the plastic bag. Therefore, it is urgent to design A kind of biodegradable plastic bag uses heat-press sealing device to solve the above problems

Embodiment 1

[0031] refer to Figure 1-4 , a heat sealing device for biodegradable plastic bags, comprising a workbench 1, four corners of the top outer wall of the workbench 1 are fixedly connected with a vertical pole 7, and the top of the vertical pole 7 is fixedly connected with a top plate 8, and the top plate 8 The bottom outer wall of the top plate 8 is provided with a sealing mechanism, and the bottom outer wall of the top plate 8 is also provided with a cooling mechanism. The workbench 1 is provided with a conveying mechanism, and the workbench 1 is also provided with a limit mechanism. mechanism.

[0032] The sealing mechanism includes a hydraulic cylinder 9, a fixed plate 20, a movable plate 24, a fixed cylinder 25, a heat-sealing block 29 and a lower support block 2. The hydraulic cylinder 9 is fixed on the bottom outer wall of the top plate 8, and the fixed plate 20 is fixed on the hydraulic cylinder. 9 piston one end, the four corners of the top outer wall of the fixed plate...

Embodiment 2

[0041] refer to Figure 5 , a heat-press sealing device for biodegradable plastic bags. Compared with Embodiment 1, this embodiment also includes limiting rollers 33 arranged on the top outer wall of the workbench 1 near both sides.

[0042] Working principle: when in use, the plastic bag can be resisted by the limit roller 33, so that the plastic bag can be fitted with the workbench 1 when moving, which is more convenient for sealing and has a better use effect.

Abstract

The invention discloses a heat-press sealing device for a biodegradable plastic bag, which comprises a workbench, four corners of the top outer wall of the workbench are fixedly connected with upright rods, and the top of the upright rod is fixedly connected with a top plate, and the bottom outer wall of the top board A sealing mechanism is provided, and the bottom outer wall of the top plate is also provided with a cooling mechanism. , a fixed plate, a movable plate, a fixed cylinder, a heat seal block and a lower support block, the hydraulic cylinder is fixed on the bottom outer wall of the top plate, and the fixed plate is fixed on one end of the piston of the hydraulic cylinder. The invention can control the deformation of the second spring when the lower pressing block is pressed down, so that the force of the heat-sealing block is moderate when the pressing block is pressed down, and the heat-sealing effect is better, and equidistant heat-press sealing can be realized to ensure that the size of each plastic bag is consistent , the effect is better.

Description

technical field [0001] The invention relates to the technical field of plastic bag production, in particular to a heat-press sealing device for biodegradable plastic bags. Background technique [0002] Biodegradable plastic refers to a type of plastic that can be degraded under the action of microorganisms such as bacteria, mold and algae that exist in nature. After degradation, it can form substances that are harmless to the environment. Because of its good degradability, it is called Widely used in the production of plastic packaging films, plastic bags and disposable plastic tableware and other supplies. [0003] At present, in the production process of biodegradable plastic bags, it is necessary to use a heat sealing device to heat seal the continuously formed garbage bags, separate the plastic bags into sections, and tear them for convenience. However, the existing heat sealing There are still some deficiencies in the device. During use, a high sealing pressure will di...
