Description

Technical Field

[0001] This utility model belongs to the technical field of printing auxiliary equipment, specifically relating to a printing dust removal device. Background Technology

[0002] In the packaging and printing industry, it is necessary to clean and remove dust from the parts to be printed before printing to avoid static electricity adsorption of dust on the surface of the parts, which may cause poor printing results. Therefore, special equipment is used to clean the parts before they enter the printing equipment. Generally, the parts are transported by a conveyor belt, and soft materials are used to wipe the parts that pass over the conveyor belt.

[0003] Chinese Patent Application No. CN202411331368.6 discloses a cardboard printing equipment, including a worktable, a support frame fixedly installed above the worktable, a linear motor fixedly installed above the support frame, a transport mechanism provided on the surface of the worktable, and a leveling device, the leveling device including a lifting frame, a leveling frame, a lifting plate, a fixing rod, a connecting plate, a fixing frame, a guide tube, a fan, leveling rollers, and a limiting rod, the lifting frame being fixedly installed at the output end of the linear motor.

[0004] For example, Chinese Patent Application No. CN202420212662.4 discloses a dust removal mechanism for printing equipment, including a housing suspended above the printed parts; a cleaning roller disposed inside the housing and in contact with the printed parts; an air chamber with a first air outlet and a second air outlet, the second air outlet facing the printed parts and the first air outlet facing the direction of the cleaning roller; and a dividing plate disposed at the rear end of the cleaning roller.

[0005] However, in the above-mentioned prior art, after the cardboard is wiped with a soft material, dust will accumulate on the surface of the cardboard after wiping. The existing device lacks a cleaning step for this dust, resulting in poor printing quality of the cardboard in the future. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A printing dust removal device, comprising:

[0008] The frame is connected to a fan;

[0009] The conveying mechanism is located at the upper end of the frame;

[0010] A cover is disposed on the upper part of the conveying mechanism and connected to the frame. The cover has a feeding end and a discharging end on both sides.

[0011] Several sets of air shower components are arranged along the conveying direction of the conveying mechanism. Each set of air shower components includes a pair of air shower heads arranged at the top and bottom of the conveying mechanism, and an air guide duct for connecting the air shower heads to the fan.

[0012] The conveying mechanism is symmetrically provided with at least one set of arc-shaped top plates on both sides, and the arc-shaped top plates are connected to the frame.

[0013] Furthermore, the arc-shaped top plate is provided with a groove containing through holes.

[0014] Furthermore, the arc-shaped top plate has multiple sets and is arranged along the conveying direction of the conveying mechanism.

[0015] Furthermore, the arc-shaped top plate has connecting columns.

[0016] Furthermore, a collection component is provided below the conveying mechanism, which includes an upward-opening dust collection hopper, a collection box, and a power component.

[0017] Furthermore, the inner wall of the dust collection hopper has an electrostatic plate.

[0018] Furthermore, the feed end and discharge end are provided with baffles that are hinged to the cover.

[0019] Furthermore, the bottom of the frame is equipped with several rollers.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] By installing an air shower component on the upper part of the conveying mechanism, high-pressure airflow is blown onto the surface of the cardboard during conveying, causing the dust attached to the surface to be blown away and collected by the set dust collection component. After being treated by this device, the residual dust on the surface of the cardboard is greatly reduced, which ensures the quality of subsequent printing processes.

[0022] The arc-shaped top plates on both sides of the conveying mechanism cause the cardboard to be conveyed in an up-and-down undulating manner during the conveying process, which causes the angle between the cardboard surface and the airflow blown out by the air shower head to change continuously, thereby increasing the dust removal effect on the cardboard surface.

[0030] like Figure 1 - Figure 3 As shown, the present invention provides a printing dust removal device, which includes a frame 1, a conveying mechanism 3, a cover 4, and multiple sets of air shower components 5.

[0031] Among them, the frame 1 is connected to the fan 2;

[0032] The conveying mechanism 3 is located at the upper end of the frame 1;

[0033] The cover 4 is located on the upper part of the conveying mechanism 3 and is connected to the frame 1. The cover 4 has a feeding end 40 and a discharging end 41 on both sides.

[0034] Several sets of air shower components 5 are arranged along the conveying direction of the conveying mechanism 3. Each set of air shower components 5 includes a pair of air shower heads 50 arranged at the upper and lower parts of the conveying mechanism 3, and an air guide duct 51 for connecting the air shower head 50 to the fan 2.

[0035] The conveying mechanism 3 is symmetrically provided with at least one set of arc-shaped top plates 6 on both sides, and the arc-shaped top plates 6 are connected to the frame 1.

[0036] When in use, the cardboard printed parts, after being initially wiped clean to remove impurities, are put into the feed end 40 and finally sent out from the discharge end 41 under the action of the conveying mechanism 3.

[0037] Because an air shower assembly 5 is installed on the upper part of the conveying mechanism 3, high-pressure airflow is blown onto the surface of the cardboard during conveying, causing the dust attached to the surface to be blown away and collected by the collection assembly 7. After being treated by this device, the residual dust on the surface of the cardboard is greatly reduced, which ensures the quality of subsequent printing processes.

[0038] The arc-shaped top plate 6 set on both sides of the conveying mechanism 3 causes the cardboard to be conveyed in an up-and-down undulating state during the conveying process, which causes the angle between the cardboard surface and the airflow blown out by the air shower head 50 to change continuously, thereby increasing the dust removal effect on the cardboard surface.

[0039] Although the arc-shaped top plate 6 is located on the side of the conveying mechanism 3, part of the printed paperboard is located at the edge of the conveying mechanism 3 and extends outward. During the paperboard conveying, the part of the paperboard that extends outward is tilted under the action of the arc-shaped top plate 6. After leaving the arc-shaped top plate 6, it rotates back to its original shape. Since there are multiple arc-shaped top plates 6, this process can be repeated many times, which increases the dust removal effect of the air shower assembly 5 on floating dust.

[0040] like Figure 2 , Figure 3 As shown, the arc-shaped top plate 6 has a groove 60 with a through hole 61.

[0041] In addition, there are multiple sets of arc-shaped top plates 6, which are arranged along the conveying direction of the conveying mechanism 3.

[0042] The arc-shaped top plate 6 has a connecting post 62. The arc-shaped top plate 6 is connected to the side of the conveying mechanism 3 of the frame 1 by the cooperation of the connecting post 62 and the bolt.

[0043] like Figure 1 As shown, a collection component 7 is also provided below the conveying mechanism 3. The collection component 7 has an upward-opening dust collection hopper 70, a collection box 71, and a power component.

[0044] The collection component 7 adopts the principle of negative pressure adsorption, and its power component is a pump or fan. Under the blowing of airflow, the internal floating dust is collected and recycled, preventing the floating dust inside the cover 4 from falling back onto the surface of the printed parts.

[0045] The dust collection hopper 70 has an electrostatic plate (not shown in the figure) installed on its inner wall. The dust blown down is attracted by electrostatic force. The inner wall of the dust collection hopper 70 is inclined, and the dust will slide down the inner wall of the dust collection hopper 70 to the collection box 71 below. After a certain amount is collected, it can be centrally transported to the outside for unified treatment.

[0046] In addition, the feed end 40 and the discharge end 41 are equipped with baffles 42 that are hinged to the cover 4. The baffles 42 can reduce the amount of dust blown off and falling outside the device, thus reducing the impact on the surrounding environment.

[0047] In addition, the bottom of the frame 1 is equipped with several casters 10. These casters 10 are omnidirectional wheels, which can facilitate the movement of the entire device and reduce transportation costs.

[0048] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
