Description

Technical Field

[0001] This utility model relates to the field of toner production technology, specifically to an automated blowing and dust removal device used on a toner bottle packaging production line. Background Technology

[0002] The printer toner bottle packaging process includes the following steps: Toner is filled into plastic bottles using a toner filling machine. The filled bottles are then placed on an automated conveyor belt and sequentially passed through capping, sealing, and labeling stations for sealing and labeling.

[0003] During the toner filling process, a layer of toner can adhere to various parts of the bottle's exterior due to static electricity. This can lead to quality issues during subsequent packaging operations, such as leakage of the aluminum foil at the bottle opening, peeling off of labels, and soiled product packaging. Therefore, it is necessary to manually clean the bottle using a compressed gas spray gun before the sealing and labeling processes.

[0004] However, manual purging has a low degree of automation and requires manpower (high labor costs); moreover, the purging process can easily cause dust to fly, pollute the workshop environment, and affect the health of workers. Utility Model Content

[0005] Therefore, this utility model provides an automated blowing and dust removal device for use on a toner bottle packaging production line to solve technical problems such as toner sticking to bottles, laborious blowing, and environmental pollution.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automated dust removal and purging device includes a purging unit, an air supply unit, a control unit, and a negative pressure purification unit. The purging unit includes an air knife cleaner disposed on the side of an automatic conveyor belt. The air knife cleaner has a strip-shaped air outlet that extends vertically and whose airflow direction is perpendicular to the conveying direction of the automatic conveyor belt. The air supply unit includes an air tank and an electromagnetic pulse valve. The outlet of the air tank is connected to the inlet of the air knife cleaner via a first air supply pipeline, and the electromagnetic pulse valve is connected in series on the first air supply pipeline. The control unit includes a laser beam switch. The transmitter and receiver of the laser beam switch are disposed opposite each other on both sides of the automatic conveyor belt, and the laser beam switch is electrically connected to the electromagnetic pulse valve. The negative pressure purification unit includes a negative pressure fan, a bag filter, and a dust suction port. The negative pressure fan is connected to the outlet of the bag filter, and the inlet of the bag filter is connected to the dust suction port, which is spaced apart from the purging unit.

[0008] Furthermore, the purging unit includes two air knife cleaners, which are located on opposite sides of the automatic conveyor belt and are staggered.

[0009] Furthermore, the purging unit also includes a fixed bracket disposed on the side of the automatic conveyor belt, and the air knife cleaner is mounted on the fixed bracket.

[0010] Furthermore, the gas supply unit also includes a second gas supply pipeline and a pressure regulating valve. One end of the second gas supply pipeline is connected to the workshop gas supply pipeline, and the other end of the second gas supply pipeline is connected to the gas inlet of the gas storage tank. The pressure regulating valve is connected in series on the second gas supply pipeline.

[0011] Furthermore, a pressure gauge is installed on the gas storage tank.

[0012] Furthermore, the first gas supply pipe and / or the second gas supply pipe are 10mm high-pressure hoses.

[0013] Furthermore, the laser beam switch is provided in two sets, located on the front and rear sides of the purging unit respectively, wherein the receiving ends of the two sets of laser beam switches are connected in parallel.

[0014] Furthermore, the negative pressure purification unit also includes a butterfly valve, which is disposed on the dust collection port.

[0015] Furthermore, the negative pressure purification unit also includes a dust collection chamber, which has a bottle inlet window and a bottle outlet window. The automatic conveyor belt passes through the bottle inlet window and the bottle outlet window in sequence. The blowing unit is located inside the dust collection chamber, and the dust suction port is located at the top of the dust collection chamber.

[0016] This utility model has the following advantages:

[0017] This utility model provides an automated blowing and dust removal device for use on a toner bottle packaging production line, located after filling and before sealing and labeling. When a bottle on the automatic conveyor belt passes a laser beam switch, the bottle blocks the laser beam, activating the switch and energizing the electromagnetic coil in the electromagnetic pulse valve. This opens the valve, allowing high-pressure gas from the gas tank to enter the air knife cleaner via the first gas supply line. The high-pressure gas is then blown out from the nozzle, cleaning the toner adsorbed on the bottle. This automated blowing eliminates the need for manual cleaning, saving labor. Furthermore, through the action of a negative pressure fan, air near the blowing unit enters the bag filter from the dust suction port. The bag filter filters the dust, retaining it within the filter and preventing dust pollution in the workshop, thus optimizing the production environment.

Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1-4 As shown, this embodiment provides an automated dust removal device, including a purging unit, an air supply unit, a control unit, and a negative pressure purification unit. The purging unit includes an air knife cleaner 2, which is disposed on the side of the automatic conveyor belt 1. The air knife cleaner 2 has a strip-shaped air outlet that extends vertically and whose blowing direction is perpendicular to the conveying direction of the automatic conveyor belt 1. The air supply unit includes an air tank 3, a ball valve 4, and an electromagnetic pulse valve 5. A drain valve 7 is provided at the bottom of the air tank 3. The air outlet of the air tank 3 is connected to the air inlet of the air knife cleaner 2 through a first air supply pipeline. The ball valve 4 and the electromagnetic pulse valve 5 are connected in series in the first air supply pipeline. The control unit includes a laser beam switch 16, with its transmitting and receiving ends disposed opposite each other on both sides of the automatic conveyor belt 1. The laser beam switch 16 is electrically connected to the electromagnetic pulse valve 5. The negative pressure purification unit includes a negative pressure fan 15, a bag filter 14, and a dust collection port 8. The negative pressure fan 15 is connected to the outlet of the bag filter 14, and the inlet of the bag filter 14 is connected to the dust collection port 8. The dust collection port 8 is spaced apart from the blowing unit.

[0028] It should be noted that "the air knife cleaner 2 is set on the side of the automatic conveyor belt 1" refers to the positional relationship. The air knife cleaner 2 is not installed on the automatic conveyor belt 1 and moves with it. In fact, quite the opposite, the air knife cleaner 2 is fixed relative to the foundation (which can be the frame of the production line or the workshop foundation) and does not move with the automatic conveyor belt 1. Similarly, the transmitting end and receiving end of the laser beam switch 16 are also fixed relative to the foundation and do not move with the automatic conveyor belt 1. Moreover, the receiving end of the laser beam switch 16 adopts the normally open mode (that is, when the receiving end receives the laser beam, the laser beam switch 16 is in the open state).

[0029] This embodiment describes an automated dust removal device used on a toner bottle packaging production line, located after the filling operation and before the sealing and labeling process. When a bottle on the automatic conveyor belt 1 passes the laser beam switch 16, the bottle body blocks the laser beam, activating the laser beam switch 16. This energizes the electromagnetic coil in the electromagnetic pulse valve 5, opening the valve. High-pressure gas from the gas tank 3 then enters the air knife cleaner 2 along the first gas supply line. The high-pressure gas is blown out from the air outlet, cleaning the toner adsorbed on the bottle body. This achieves automated cleaning, eliminating the need for manual cleaning and saving labor. The negative pressure generated by the negative pressure fan 15 passes through the bag filter 14 and the dust collection pipeline, and is transmitted to the dust collection suction port 8 installed in the blowing area. The flying dust is sucked into the bag filter 14. The dust-laden air is filtered by the bag filter 14, leaving the dust inside the dust collector. The filtered clean air is discharged through the exhaust pipe of the negative pressure fan 15. In this way, dust pollution in the workshop can be effectively avoided and the production environment can be optimized.

[0030] In this embodiment, the purging unit includes two air knife cleaners 2, which are located on opposite sides of the automatic conveyor belt 1 and are staggered. This allows for dual-sided airflow cleaning of the packaging bottles on the automatic conveyor belt 1, ensuring both sides of the bottles are cleaned. The staggered arrangement of the air knife cleaners 2 effectively avoids the weakening of the airflow caused by the purging, guaranteeing the cleaning effect.

[0031] In this embodiment, the purging unit also includes a fixed bracket disposed on the side of the automatic conveyor belt 1, and the air knife cleaner 2 is mounted on the fixed bracket. When the air knife cleaner is purging, the strong air force will bring a reaction force to the air knife cleaner, and the fixed bracket will stably fix the air knife cleaner to the foundation of the production line.

[0032] In this embodiment, the gas supply unit also includes a second gas supply pipeline and a pressure regulating valve 6. One end of the second gas supply pipeline is connected to the workshop gas supply pipeline, and the other end of the second gas supply pipeline is connected to the air inlet of the gas storage tank 3. The pressure regulating valve 6 is connected in series on the second gas supply pipeline.

[0033] In this embodiment, a pressure gauge is installed on the gas storage tank 3 to observe the gas pressure value in the gas storage tank 3. Generally, the pressure gauge has a range of 0-10 bar.

[0034] In this embodiment, the first and / or second air supply pipes are 10mm high-pressure hoses. In practical applications, if the air tank 3 is far from the wind-powered cleaner (meaning the pipe between them is long, for example, greater than 3m), the first air supply pipe uses a 10mm high-pressure hose; while the second air supply pipe can be a steel pipe connected to the workshop air supply pipe.

[0035] In this embodiment, two sets of laser beam switches 16 are provided, located at the front and rear sides of the purging unit, respectively, with the receiving ends of the two sets of laser beam switches 16 connected in parallel. When a packaged bottle on the automatic conveyor belt 1 moves towards the purging unit, it first enters the space between the laser beam switches 16 located at the front of the purging unit. The laser beam switches 16 are activated by the packaged bottle, the electromagnetic pulse valve 5 is turned on, and the two air knife cleaners 2 output compressed or high-pressure air to purge the bottle. When the packaged bottle leaves the rear laser beam switch 16, the electromagnetic pulse valve 5 closes, and the purging unit stops purging. The two laser beam switches 16 are located at the front and rear sides of the purging unit, with their receiving ends connected in parallel. This ensures that when the packaged bottle passes the two air knife cleaners 2, the two air knife cleaners 2 remain in a purging state, and when the packaged bottle leaves the purging unit, the two air knife cleaners 2 stop purging.

[0036] In this embodiment, the negative pressure purification unit also includes a butterfly valve, which is installed on the dust collection inlet 8. The dust collection air volume can be adjusted by the butterfly valve installed on the dust collection inlet 8.

[0037] Effective covering devices should be installed around the purging area, and the dust collection port should be placed in a scientifically effective location. Otherwise, a large amount of dust leakage will occur, reducing the dust collection efficiency. In this embodiment, the negative pressure purification unit also includes a dust collection chamber 10, which is provided with a bottle inlet window 12 and a bottle outlet window 13. The automatic conveyor belt 1 passes through the bottle inlet window 12 and the bottle outlet window 13 in sequence. The purging unit is located in the central area of ​​the dust collection chamber 10, and the dust collection suction port 8 is located on the top of the dust collection chamber 10. Specifically, the dust collection chamber 10 is constructed of 50mm thick rock wool purification panels, with dimensions (length × width × height) of 1.2m × 1.2m × 2.5m. This effectively accommodates a large amount of dust-laden air, preventing dust overflow and pollution of the workshop, while occupying a relatively small workshop area. The dust collection port is installed on the roof directly above the purging device. After the fan is turned on, a negative pressure is created inside the dust removal chamber 10. Air enters the dust removal chamber 10 through the inlet window 12 and the outlet window 13, forming an airflow field 11 within the chamber 10. This airflow field 11 guides dust towards the dust removal port, reducing dust residence time within the chamber, and also prevents dust from overflowing from the inlet window 12 and the outlet window 13. Generally, the dust removal chamber 10 is equipped with a door for easy equipment maintenance and cleaning, and the door frame is fitted with a sealing strip. The rock wool filling of the chamber effectively shields the blowing noise, improving the noise environment of the workshop.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
