Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment protection devices, and specifically relates to a dust-proof device for printing equipment. Background Technique

[0002] Dust-proof devices for printing equipment play a crucial role in the printing industry. Their main function is to prevent dust and other pollutants from entering the interior of the equipment, thereby maintaining the normal operation of the equipment, extending the service life of the equipment, and ensuring printing quality. When printing equipment is in operation, ink dust is generated. Since there are many types of printing equipment in a printing factory workshop to meet various printing needs, when printing a batch of products, there will be a phenomenon that other printing equipment is not used temporarily. Therefore, dust pollution will occur to the printing equipment that is not used temporarily. Over time, it will affect the normal operation of the equipment and also reduce the service life of the equipment. Currently, plastic films are used for protection. However, for equipment that has just been used, the temperature is relatively high. For example, for a bookbinding machine, the temperature will be even higher. At this time, covering it with a plastic film is not conducive to the heat dissipation of the equipment. If the heat cannot be dissipated in time, it will also affect the service life of the equipment. To address the above technical problems, it is necessary to invent a dust-proof device that can dissipate heat in a timely manner and can conveniently protect printing equipment that is not used temporarily. Content of the Utility Model

[0003] To address the above technical problems, the utility model provides a dust-proof device for printing equipment that can dissipate heat quickly.

[0004] To solve the above technical problems, a dust-proof device for printing equipment according to the utility model includes a box body. The box body has a bottomless structure. A number of heat dissipation holes are fixedly connected to both sides of the box body. Electrostatic adsorption plates are fixedly connected to both sides inside the box body, and the positions of the electrostatic adsorption plates correspond to those of the heat dissipation holes. The front end of the box body is a transparent plate. A wire hole is opened at the bottom of the rear end of the box body. A blower is fixedly connected to the top of the box body, and a backflow prevention device is fixedly connected to the bottom of the blower.

[0005] The backflow prevention device includes a housing. The housing has a bottomless structure. The top of the housing is communicated with the bottom of the blower. A fixing plate is fixedly connected to the bottom inside the housing. One end of the fixing plate is hinged to a baffle through a hinge, and a limiting block is fixedly connected to the upper end inside the housing.

[0006] Furthermore, suspension rings are fixedly connected to both sides of the box body, and the suspension rings are located above the heat dissipation holes.

[0007] The utility model has the following advantages compared with the prior art:

[0008] 1. The utility model sets an electrostatic adsorption plate at the heat dissipation holes. After the electrostatic adsorption plate is powered on, the conductive plate will generate an electrostatic field. At this time, if there are uncharged objects nearby (such as dust, powder, etc.), due to the phenomenon of electrostatic induction, these objects will induce charges with opposite polarities to the electrostatic adsorption plate on the side close to the electrostatic adsorption plate. Due to the mutual attraction of opposite charges, these objects will be adsorbed onto the electrostatic adsorption plate. Therefore, it can effectively adsorb the dust in the flowing air and prevent harm to the protected equipment. By setting a blower at the top, rapid heat dissipation of the protected equipment can be achieved, and in cooperation with the electrostatic adsorption plate, dust will not enter the protected equipment through the heat dissipation holes.

[0009] 2. The utility model further prevents the situation where dust enters through the blower during the non - use process of the blower by installing a check device at the bottom of the blower, and better protects the equipment in the box body. Brief Description of the Drawings

[0014] The following further describes the utility model with reference to the drawings.

[0015] As Figures 1 to 3 shown, a dust - proof device for a printing device includes a box body 1. The box body 1 has a bottomless structure. A number of heat dissipation holes 2 are fixedly connected to both sides of the box body 1. Electrostatic adsorption plates 5 are fixedly connected to both sides inside the box body 1, and the positions of the electrostatic adsorption plates 5 correspond to the heat dissipation holes 2. The front end of the box body 1 is a transparent plate 4, which is convenient for identifying the protected equipment. A wire hole 7 is opened at the bottom of the rear end of the box body 1, which is convenient for the lines of the equipment to pass through. A blower 3 is fixedly connected to the top of the box body 1, and a check device 8 is fixedly connected to the bottom of the blower 3.

[0016] The backflow prevention device 8 includes a housing 805. The housing 805 has a bottomless structure. The top of the housing 805 is communicated with the bottom of the fan 3. A fixing plate 801 is fixedly connected to the inner bottom of the housing 805. One end of the fixing plate 801 is hinged with a baffle 802 through a hinge 803. A limiting block 804 is fixedly connected to the upper end inside the housing 805 to prevent the baffle 802 from opening too much and falling on the fixing plate 801 and being unable to return to its position when the fan 3 is ventilating.

[0017] To facilitate the appropriation of the protection device, lifting rings 6 are fixedly connected to both sides of the box body 1. The lifting rings 6 are located above the heat dissipation holes 2.

[0018] The working process of this embodiment is as follows:

[0019] When it is necessary to protect the unused printing equipment, the device is lifted by a lifting device or an operator through the lifting ring 6 and covered on the equipment to be protected. If the printing equipment has just been used, the electrostatic adsorption plate 5 is started and the fan 3 is turned on. The fan 3 pumps out gas outward. The outside gas enters through the heat dissipation holes 2 and the dust is removed by the electrostatic adsorption plate 5. After a certain period of time, when the printing equipment has cooled down, the fan 3 is turned off, and the electrostatic adsorption plate 5 continues to work to continuously adsorb and remove the dust in the flowing gas. Among them: when the fan 3 is working, the air flow lifts the baffle 802 during the rising process. After rising, one end of the baffle 802 is hinged with the fixing plate 801 through the hinge 803, and the other end is restricted by 804 to prevent 802 from falling on the fixing plate 801 and being unable to return to its normal position subsequently. When the fan 3 stops, the baffle 802 returns to its position and cooperates with the fixing plate 801 to block and seal the bottom of the housing 805 to prevent dust from entering the device through the fan 3 and the housing 805 when the fan 3 is not working.
