Description

Technical Field

[0001] This utility model relates to the field of plastic bag blown film technology, and in particular to a dust suppression device for plastic bag blown film. Background Technology

[0002] Film blowing is a plastic processing method that involves heating and melting plastic particles and then blowing them into a thin film. Typically, the polymer is extruded into a tubular preform, and under good melt flow conditions, the preform is blown into the required thickness by high-pressure air. After cooling and shaping, it becomes a film. Plastic bag blowing machines require the use of plastic bag blowing dust suppression equipment during the production process.

[0003] The existing plastic bag blown film dust suppression equipment has the following disadvantages: 1. It is not convenient to install on the frame of the plastic bag blown film machine, and its shock resistance is poor. Therefore, we propose a new plastic bag blown film dust suppression equipment. Summary of the Invention

[0004] The main objective of this invention is to provide a dust suppression device for blown film on plastic bags, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust suppression device for blown film on plastic bags includes a U-shaped mounting plate, damping shock absorbers, mounting vertical plates, and a hemispherical cover. Damping shock absorbers are bolted to both ends of one side of the U-shaped mounting plate. An end plate is bolted to the movable end of the damping shock absorber. A mounting vertical plate is welded between the end plates, and a water pump is mounted on one side of the mounting vertical plate via a mounting base. A time relay switch is mounted on the lower end of the water pump via screws. The hemispherical cover is mounted on the other side of the mounting vertical plate via an arc-shaped mounting bracket. A connecting straight pipe is provided through one side of the hemispherical cover, and one end of the connecting straight pipe is connected to an atomizing nozzle.

[0007] Furthermore, the output port of the water pump is connected to a straight pipe, and the input port of the water pump is connected to a delivery hose.

[0008] Furthermore, the output terminal of the time relay switch is electrically connected to the input terminal of the water pump via a wire. The time relay switch automatically controls the working time of the water pump, and automatically shuts off after the set time is reached, thus achieving an energy-saving effect.

[0009] Furthermore, mounting bolts are installed on one side of the U-shaped mounting plate through bolt holes. The U-shaped mounting plate and mounting bolts facilitate the installation of the entire device on the frame of the plastic bag blown film machine, making it convenient for installation and disassembly.

[0010] Furthermore, the hemispherical cover is specifically made of PU material.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model relates to a dust suppression device for blown film on plastic bags. The device is installed on the frame of a blown film machine using a U-shaped mounting plate and mounting bolts, which is convenient for installation and disassembly. The device is connected to a water tank using a conveying hose. The water in the tank is pumped into the atomizing nozzle and sprayed out to quickly suppress dust. The device is also equipped with a hemispherical cover to concentrate the spraying of the atomized liquid.

[0013] 2. This utility model relates to a plastic bag blown film dust suppression device, which uses a time relay switch to automatically control the working time of the water pump and automatically shuts it off after the set time, thus achieving an energy-saving effect. When the entire device is subjected to external factors and vibrates significantly, a damping shock absorber is used to resist the vibration and also to buffer and dissipate energy, protecting the atomizing nozzle from damage.
