A new type of exposure machine with dust removal function

Abstract

This utility model discloses a novel plate-making machine with dust removal function, belonging to the field of printing equipment technology. It includes setting up an ion fan to release positive and negative ions to eliminate the accumulation of static electricity on the surface of the printing plate and the surrounding environment, avoiding the re-adhesion of cleaned dust onto the plate surface due to static adsorption, and adsorbing new pollutants in the environment onto the surface of the printing plate. The negative pressure duct, through the airflow acceleration-negative pressure effect based on Bernoulli's principle, can form a strong local suction force, which can efficiently remove tightly attached dust, fibers, and pollutants in crevices or complex structures, solving the "cleaning dead corner" problem of traditional brushes and ordinary vacuum adsorption. In the dust removal process of the plate-making machine, the dust removal method of the negative pressure duct based on the Venturi principle and the ion fan can give full play to the synergistic advantages of the two technologies and effectively make up for the defects of traditional single dust removal methods.

Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and in particular to a new type of exposure machine with dust removal function. Background Technology

[0002] Exposure machines primarily utilize pressure, including atmospheric pressure and mechanical pressure, to ensure a tight fit between the original plate and the photosensitive plate. Through a photochemical reaction, the image on the original plate is precisely transferred onto the photosensitive plate. In the printing of publications such as books, newspapers, and magazines, exposure machines are used to create printing plates, transferring text, images, and other information onto them to prepare for subsequent printing processes.

[0003] The cleanliness of the working environment of the exposure machine directly affects the plate-making quality. Dust removal is a core aspect of exposure machine maintenance and operation, but currently common dust removal methods have many shortcomings, as follows:

[0004] 1. Dust removal with a brush: Incomplete cleaning and easy to damage the printing plate;

[0005] 2. Compressed air dust removal: It easily introduces new pollutants and the pressure is difficult to control;

[0006] 3. Vacuum adsorption dust removal: uneven suction and easy to miss particles;

[0007] 4. Electrostatic dust removal: greatly affected by the environment and carries the risk of residue.

[0008] The purpose of this invention is to provide a novel exposure machine with dust removal function to solve the problems mentioned in the background art. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution: a novel exposure machine with dust removal function, characterized in that: it includes an exposure machine body, an ion air duct assembly movably installed on the top of the exposure machine body, and an ion fan body fixed to the top of the ion air duct assembly. Linear transmission components for sliding are provided on both sides of the ion air duct assembly and the ion fan body. The exposure machine body includes an exposure machine housing and an exposure machine cover plate connected by a hinge assembly. The ion air duct assembly includes negative pressure conduits movably connected to both sides of the linear transmission components. An air inlet is provided at the connection between the top of the negative pressure conduit and the ion fan body, and an air outlet communicating with the air inlet is provided inside the negative pressure conduit. A contraction section is provided between the air inlet and the air outlet, and a dust suction port is provided at the bottom of the contraction section. An installation groove is provided at the top of the negative pressure conduit for installing a detachable multi-layer filter assembly.

[0010] Furthermore, several fixing posts are provided on both sides of the top of the exposure machine housing, and a screw and a slide rod are respectively provided between each set of fixing posts on both sides of the exposure machine housing. A motor for driving is provided at one end of the screw, and a fixing plate assembly for fixing the motor is installed at the bottom end of the motor. The screw is connected to the slide rod on the other side through a negative pressure conduit.

[0011] Furthermore, a threaded slot slider is provided at the connection between the negative pressure conduit and the screw. The threaded slot slider has a threaded slot inside, which is used to cooperate with the threaded slot slider to perform transmission through friction.

[0012] Furthermore, a circular slotted slider is provided at the connection between the negative pressure conduit and the slide rod, and a circular slot is formed inside the circular slotted slider.

[0013] Furthermore, the detachable multi-layer filter assembly includes a filter screen and a magnetic fixing plate disposed on the top of the filter screen.

[0014] Furthermore, a limiting groove is provided on the inner side of the negative pressure conduit to restrict the movement of the filter screen, and a fixing rod is provided at the bottom of the negative pressure conduit. The fixing rod is connected to the circular groove slider and the threaded groove slider.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention eliminates static electricity buildup on the printing plate surface and surrounding environment by using an ion fan to release positive and negative ions. This prevents dust that has been removed from re-adhering to the plate due to static adsorption, and avoids new pollutants in the environment being adsorbed onto the printing plate surface. The negative pressure duct, based on Bernoulli's principle, accelerates airflow and creates a negative pressure effect, forming a strong local suction force that can efficiently remove tightly attached dust, fibers, and pollutants in crevices or complex structures. This solves the "dead corner" problem of traditional brushes and ordinary vacuum adsorption. In the dust removal process of the plate exposure machine, the combination of a negative pressure duct based on the Venturi principle and an ion fan can fully leverage the synergistic advantages of the two technologies and effectively compensate for the shortcomings of traditional single dust removal methods.

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] Please see Figures 1 to 5As shown, a novel exposure machine with dust removal function includes an exposure machine body 1, an ion air duct assembly 3 movably installed on the top of the exposure machine body 1, and an ion fan body 4 fixed on the top of the ion air duct assembly 3. Linear transmission components 2 for sliding are provided on both sides of the ion air duct assembly 3 and the ion fan body 4.

[0031] Specifically, the exposure machine body 1 includes an exposure machine housing 101 and several fixing posts 203 arranged on both sides of the top of the exposure machine housing 101. A screw 204 and a slide bar 205 are respectively arranged between each set of fixing posts 203 on both sides of the exposure machine housing 101. A motor 201 for driving is arranged at one end of the screw 204. A fixing plate assembly 202 for fixing the motor 201 is installed at the bottom end of the motor 201. The screw 204 is connected to the slide bar 205 on the other side through a negative pressure conduit 302.

[0032] Specifically, the exposure machine housing 101 and the exposure machine cover 102 connected by the hinge assembly, the ion air duct assembly 3 includes a negative pressure duct 302 movably connected to both sides of the linear transmission assembly 2, and the negative pressure duct 302 is made of magnetic material. An air inlet 402 is provided at the connection between the top of the negative pressure duct 302 and the ion fan body 4, and an air outlet 306 communicating with the air inlet 402 is provided inside the negative pressure duct 302. A constriction section is provided between the air inlet 402 and the air outlet 306, and a dust suction port 305 is provided at the bottom of the constriction section.

[0033] Specifically, a threaded slot slider 303 is provided at the connection between the negative pressure conduit 302 and the screw 204. The threaded slot slider 303 has a threaded slot inside, which is used to cooperate with the screw 204 for transmission through friction. A circular slot slider 301 is provided at the connection between the negative pressure conduit 302 and the slide rod 205. The circular slot slider 301 has a circular slot inside, and the slide rod 205 passes through the circular slot slider 301. A limiting groove 307 is provided at the connection between the inner side of the negative pressure conduit 302 and the bottom end of the filter screen 501 to restrict the movement of the filter screen 501. A fixing rod 304 is provided at the bottom of the negative pressure conduit 302. The fixing rod 304 is connected to the circular slot slider 301 and the threaded slot slider 303. The linear transmission component 2 drives the negative pressure conduit 302 to move at a uniform speed. During the movement, the ion outlet 306 and the dust suction port 305 are arranged in a progressive manner to ensure that static electricity neutralization precedes dust adsorption, forming "neutralizing static electricity first → adsorbing dust later". The progressive cleaning path involves the ion fan continuing to run after the negative pressure conduit 302 completes full-page scanning and resets, performing secondary electrostatic neutralization on the printing plate surface to ensure that the residual electrostatic voltage is ≤±30V, further reducing the dust adhesion rate.

[0034] Specifically, the surface of the filter screen 501 is W-shaped, which can significantly increase the surface area and enhance the dust capture capacity. The top of the negative pressure conduit 302 has an installation groove for installing the detachable multi-layer filter assembly 5. The detachable multi-layer filter assembly 5 includes the filter screen 501 and a magnetic fixing piece 502 set at the top of the filter screen 501. When the airflow carrying dust enters the filter screen 501, the ions charge the dust particles. Through the principle of "like charges repel and unlike charges attract", the adhesion of dust to the surface of the filter screen 501 is enhanced, reducing filter clogging.

[0035] Working principle: During use, the motor 201 is started by the control unit of the exposure machine, so that the motor 201, which is fixed at the top of the fixed plate assembly 202, drives the screw 204 set between the fixed columns 203. One end of the negative pressure conduit 302 is connected to the screw 204, and the connection is provided with a threaded groove slider 303 with a threaded hole groove inside. The screw 204 passes through the threaded hole groove of the threaded hole groove slider 303. When the screw 204 rotates, the threaded hole groove slider 303 moves linearly through friction, thereby driving the negative pressure conduit 302 to move. The other end of the negative pressure conduit 302 is connected to the slide rod 205, and the connection is provided with a circular hole groove slider 301 with a circular hole groove inside. The slide rod 205 passes through the circular hole groove of the circular hole groove slider 301, which can fix the negative pressure conduit 302 and prevent it from twisting due to friction with the screw 204.

[0036] An ion fan body 4 is installed at the top of the negative pressure duct 302, and an air inlet 402 for air intake is provided at the connection between the negative pressure duct 302 and the ion fan housing 401. An air outlet 306 for air exhaust is provided at the bottom of the negative pressure duct 302. A converging section is provided directly between the air inlet 402 and the air outlet 306. A dust suction port 305 for air intake is provided at the bottom of the inner side of the converging section. A fixing rod 304 for support is provided at the bottom of the outer side of the converging section. The dust suction port 305 is installed through the middle of the fixing rod 304. When the ion fan body 4 is started, the airflow with positive and negative ions is generated and flows into the negative pressure duct 302 through the air inlet 402 and flows out from the air outlet 306, thereby generating suction at the dust suction port 305. The dust is then absorbed by the suction generated by the negative pressure at the dust suction port 305. The absorbed dust is captured by the filter screen 501 above the outlet of the air outlet 306 along with the airflow.

[0037] The filter screen 501 has a W-shaped surface and a magnetic fixing piece 502 for fixing at the top. The magnetic fixing piece 502 has magnetic attraction and can be firmly attached to the outside of the mounting groove at the top of the negative pressure duct 302. The negative pressure duct 302 and the bottom of the filter screen 501 are provided with air outlets 306, so that the filter screen 501 is firmly fixed in the negative pressure duct 302.
