Description

Technical Field

[0001] This utility model relates to the field of screen dust removal, and in particular to an electrostatic dust removal device for monitoring screen processing. Background Technology

[0002] Surveillance screens are the core display terminals of closed-circuit monitoring systems, primarily used to present images captured by cameras in real time, acting as the "visual hub" in security, industry, transportation, and other fields. They feature high definition, high contrast, and wide viewing angles, supporting continuous operation 24 / 7. Classified by type, they include LCD, LED, and DLP splicing screens, covering a wide range of sizes and suitable for various scenarios. For example, LCD monitors offer accurate color reproduction, making them suitable for security viewing; LED screens have seamless splicing, suitable for large-screen splicing; and DLP screens, with their ultra-narrow bezels, are used in high-end command centers. During the manufacturing process, the surface of the surveillance screen needs to be dust-removed to facilitate the subsequent application of a protective film or other treatments.

[0003] When existing electrostatic dust removal mechanisms are used to remove dust from monitoring screens, if the distance between the electrostatic dust removal mechanism and the screen is too close, there is a possibility that the electrostatic dust removal mechanism may discharge and break down the monitoring screen, causing damage to the screen. If a single brush roller is used to remove dust from the monitoring screen, the dust on the monitoring screen may not be completely cleaned, making the existing dust removal devices not very practical.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an electrostatic dust removal device for monitoring screen processing to solve the aforementioned technical defects.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An electrostatic dust removal device for monitoring screen processing includes a conveyor frame, a dust removal mechanism above the conveyor frame, the dust removal mechanism including a housing, an air guide frame one fixedly connected to one end of the housing, an air guide frame two fixedly connected to one side of the air guide frame one, an electrostatic precipitator fixedly mounted on the top of the housing by bolts, a centrifugal fan fixedly mounted on the top of the housing by bolts, a stepper motor two fixedly mounted on the outside of the housing by bolts, and a soft brush roller rotatably connected inside the housing.

[0008] Preferably, the conveyor frame has symmetrically distributed rollers inside, each roller is rotatably connected to the conveyor frame, a conveyor belt is sleeved on the outside of the rollers, and a stepper motor is fixedly mounted on one side of the conveyor frame by bolts. The drive shaft of the stepper motor is fixedly connected to the shaft at one end of one of the rollers. The housing is located outside the conveyor frame and placed on the ground.

[0009] Preferably, windproof curtains are installed at both ends of the housing, the air guide frame one and the air guide frame two are internally connected, the housing is also provided with a fixedly connected guide plate one, one side of the guide plate one is provided with a fixedly connected air guide frame three, the other end of the housing is provided with a fixedly connected guide plate two, and the air inlet of the electrostatic precipitator is located at the bottom and is connected to the inside of the housing.

[0011] Preferably, the centrifugal fan has a fixedly connected and internally interconnected three-way ventilation duct at its air outlet. One end of the three-way ventilation duct is inserted into the air guide frame 1, and the other end of the three-way ventilation duct passes through the guide plate 1 and is then inserted into the air guide frame 3.

[0012] Preferably, the drive shaft of the second stepper motor is fixedly connected to the shaft at one end of the soft brush roller, and the soft brush roller is located between the first guide plate and the first air guide frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention involves placing the monitoring screen to be cleaned on a conveyor belt, with a stepper motor driving a roller to transport the screen into the housing. First, an electrostatic precipitator and a centrifugal fan work together to blow clean air through a three-way guide frame to remove larger dust particles from the screen surface. The dust-laden air is then circulated back to the electrostatic precipitator for purification via a second guide plate. After initial dust removal, the screen continues to be transported to a soft brush roller, where a stepper motor drives the brush roller to rotate and remove residual dust. Simultaneously, a guide frame assists in blowing air to enhance the dust removal effect, while a second guide frame cleans the dust accumulated inside the brush bristles. The dust-laden air is then guided back to the electrostatic precipitator for further treatment via a first guide plate.

[0015] This invention employs a multi-step combined dust removal technology, which takes into account both large and fine dust removal operations; it achieves closed-loop purification of dust-laden airflow through an air circulation system to avoid secondary pollution; it improves cleaning efficiency through the synergistic effect of soft brush rollers and directional airflow; and it reduces manual intervention through automated conveying and dust removal processes, thereby ensuring the cleanliness of the screen surface.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 - Figure 5 As shown, this utility model is an electrostatic dust removal device for monitoring screen processing, including a conveyor frame 1. The conveyor frame 1 has symmetrically distributed rollers 11 inside, and each roller 11 is rotatably connected to the conveyor frame 1. A conveyor belt 12 is sleeved on the outside of the rollers 11. A stepper motor 13 is also fixedly mounted on one side of the conveyor frame 1 by bolts. The drive shaft of the stepper motor 13 is fixedly connected to the shaft at one end of one of the rollers 11. A dust removal mechanism 2 is provided above the conveyor frame 1. The dust removal mechanism 2 includes a housing 21, which is located outside the conveyor frame 1 and placed on the ground.

[0026] Both ends of the housing 21 are equipped with windproof curtains 22, which are made of soft material. One end of the housing 21 is provided with a fixedly connected air guide frame 23, and one side of the air guide frame 23 is provided with a fixedly connected air guide frame 24. The interiors of the air guide frame 23 and the air guide frame 24 are connected. The interior of the housing 21 is also provided with a fixedly connected guide plate 25, and one side of the guide plate 25 is provided with a fixedly connected air guide frame 26. The other end of the housing 21 is provided with a fixedly connected guide plate 27. An electrostatic precipitator 28 is also fixedly installed on the top of the housing 21 by bolts. The air inlet of the electrostatic precipitator 28 is located at the bottom and is connected to the interior of the housing 21.

[0027] The outlet of the electrostatic precipitator 28 is provided with a fixedly connected outlet pipe 29. A centrifugal fan 30 is also fixedly connected to the top of the housing 21 by bolts. One end of the centrifugal fan 30 is provided with a fixedly connected drive motor 301, which is used to drive the centrifugal fan 30. The inlet of the centrifugal fan 30 is fixedly connected to the other end of the outlet pipe 29. A three-way ventilation pipe 31 is fixedly connected and internally connected at the outlet of the centrifugal fan 30. One end of the three-way ventilation pipe 31 is inserted into the air guide frame 23, and the other end of the three-way ventilation pipe 31 passes through the guide plate 25 and is inserted into the air guide frame 26.

[0028] A stepper motor 32 is fixedly connected to the outer side of the housing 21 by bolts. A soft brush roller 33 is rotatably connected inside the housing 21. The drive shaft of the stepper motor 32 is fixedly connected to the shaft at one end of the soft brush roller 33. The soft brush roller 33 is located between the guide plate 25 and the air guide frame 23. The lower end of the air guide frame 24 is at the same height as the upper brush bristles of the soft brush roller 33. When air enters the air guide frame 24, the air guide frame 24 directs the air to the upper brush bristles of the soft brush roller 33, thereby blowing out the dust inside the brush bristles.

[0029] The working process and principle of this utility model are as follows:

[0030] In use, first place the monitoring screen to be cleaned above the conveyor belt 12, then start the stepper motor 13 to drive the roller 11 to rotate. The roller 11 drives the conveyor belt 12 to transport the monitoring screen on it until the monitoring screen is transported into the housing 21. At this time, the monitoring screen first reaches the bottom of the guide plate 27. Then start the electrostatic precipitator 28 and the drive motor 301. The drive motor 301 drives the centrifugal fan 30 to run, thereby transporting the dust-removed air in the electrostatic precipitator 28 to the three ventilation ducts 31. Then the dust-free air is blown towards the monitoring screen through the air guide frame 26, thereby blowing out the larger dust on the monitoring screen.

[0031] Subsequently, the dust-laden air is guided by guide plate 27 and blown back into electrostatic precipitator 28 for dust removal. After initial dust removal, the monitoring screen continues to be conveyed forward until it reaches below the soft brush roller 33. At this time, stepper motor 2 32 is started, which drives the soft brush roller 33 to rotate. The soft brush roller 33 further brushes away the dust on the monitoring screen. At the same time, the air in guide frame 1 23 is blown onto the monitoring screen to assist the soft brush roller 33 in dust removal. Guide frame 2 24 directs the air to the brush bristles above the soft brush roller 33, thereby blowing out the dust in the bristles. The blown-out dust-laden air is guided by guide plate 1 25 and blown into electrostatic precipitator 28 for dust removal, thus completing the multi-step dust removal operation of the monitoring screen.
