Description

Technical Field

[0001] This utility model relates to the field of printing plate roller technology, and in particular to an automatic sieving and impurity removal device for submerged arc welding flux used in printing plate roller processing. Background Technology

[0002] In the field of printing plate roller processing, submerged arc welding is a commonly used welding process. The quality of the flux directly affects the welding effect. Traditional flux treatment mostly relies on manual screening and impurity removal, which is inefficient and easily introduces secondary pollution. In recent years, automated screening equipment has gradually become popular, but there are still few special equipment for the characteristics of submerged arc welding flux.

[0003] Existing technologies mostly use vibrating screens or airflow separation, but they are difficult to balance the need for high-precision screening with the thorough removal of impurities. In addition, problems such as low flux recovery rate and frequent equipment maintenance also restrict the improvement of production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide an automatic sieving and impurity removal device for submerged arc welding flux used in printing plate roller processing, which addresses the problem that traditional flux processing equipment cannot perform high-precision sieving and thorough removal of impurities.

[0005] An automatic screening and impurity removal device for submerged arc welding flux in printing plate roller processing includes: a box and a permanent magnet roller disposed therein;

[0006] A dispersing component, wherein the dispersing component is disposed below the permanent magnet drum;

[0007] The dispersing component includes a layered shell disposed below the permanent magnet roller and fixed to the inner wall of the box, and a shovel plate is provided on one side inside the layered shell.

[0008] In one embodiment, the dispersion component further includes a reflux plate disposed at the inlet of the layered shell, the reflux plate being arc-shaped.

[0009] In one embodiment, the length of the shovel plate is the same as the internal length of the layered shell, the shovel plate is inclined, and the bottom of the shovel plate is at the same height as the bottom of the layered shell.

[0010] In one embodiment, the surface of the shovel plate is provided with a plurality of guide strips arranged in a rectangular array, and the angles of the plurality of guide strips are arranged in a fan shape.

[0011] In one embodiment, a conveyor belt is disposed inside the housing and below the permanent magnet roller, and the layered shell is located above the conveyor belt.

[0012] In one embodiment, a screening mechanism is provided inside the housing and above the permanent magnet drum, and a guide plate fixed to the inner wall of the housing is provided below the screening mechanism.

[0013] In one embodiment, an adsorption shell is provided on one side of the box, and an adsorption tube is connected to the outside of the adsorption shell. A gas separation mechanism is provided on one side of the box and below the conveyor belt.

[0014] Beneficial effects

[0015] 1. By setting up a dispersion component, the flux pile can be leveled and dispersed when it falls onto the surface of the conveyor belt. The thickness of the flux passing through the permanent magnet roller can be controlled to ensure that a single layer or a thin layer passes through the permanent magnet roller. This can reduce the accumulation of particles of different properties in the flux, improve the adsorption effect of the permanent magnet roller on impurities, and effectively reduce the residue of flux impurities.

[0016] 2. By integrating the permanent magnet drum, screening mechanism and air separation mechanism to work together, the particle size can be precisely controlled. Secondly, the permanent magnet drum efficiently removes ferrous impurities. Finally, the air separation thoroughly removes light non-metallic impurities, which can effectively improve the overall efficiency of the impurity removal operation. Attached Figure Description

[0029] The following is combined Figures 1-4This invention describes an automatic sieving and impurity removal device for submerged arc welding flux used in printing plate roller processing.

[0030] In one embodiment, an automatic screening and impurity removal device for submerged arc welding flux in printing plate roller processing includes: a housing 1 and a permanent magnet roller 4 disposed therein;

[0031] Dispersion component 8 is disposed below permanent magnet roller 4;

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the dispersing component 8 includes a layered shell 801 disposed below the permanent magnet roller 4 and fixed to the inner wall of the housing 1. A shovel plate 803 is disposed on one side inside the layered shell 801. The length of the shovel plate 803 is the same as the internal length of the layered shell 801. The shovel plate 803 is designed with an inclination. The bottom of the shovel plate 803 is at the same height as the bottom of the layered shell 801. Multiple guide bars 804 are arranged in a rectangular array on the surface of the shovel plate 803. The angle of the multiple guide bars 804 is arranged in a fan shape.

[0033] First, the flux enters the layered shell 801 via the conveyor belt 7. Since the space inside the inlet of the layered shell 801 is relatively large, the flux pile can be leveled. At this time, the flux above the flux pile that is higher than the first space of the layered shell 801 will come into contact with the reflow plate 802. Since the reflow plate 802 is arc-shaped, the flux will be guided backward along the arc of the reflow plate 802, which can block excess flux and prevent the flux from accumulating and causing blockage.

[0034] When the flux comes into contact with the spatula 803, the flux pile will be dispersed into multiple equal parts and evenly spread on the surface of the conveyor belt 7 by multiple guide bars 804 with a fan-shaped design on the surface of the spatula 803, thus improving the uniformity of flux spreading and improving the completeness of impurity adsorption by the permanent magnet roller 4.

[0035] The dispersion component 8 also includes a return plate 802 disposed at the inlet of the layered shell 801, the return plate 802 being arc-shaped;

[0036] When the flux pile enters the space at the exit, the height of this space is low, so the thickness of the flux pile can be reduced. When the flux pile comes into contact with the shovel plate 803, it will be scooped up by the inclined shovel plate 803 and fall back onto the surface of the conveyor belt 7. This step can turn the flux over and also make the flux loose.

[0037] A conveyor belt 7 is installed inside the housing 1 and below the permanent magnet roller 4, and the layered shell 801 is located above the conveyor belt 7.

[0038] It should be noted that the layered shell 801 is located above the conveyor belt 7, but its lower part does not contact the conveyor belt 7. The main function of the layered shell 801 is to level the flux pile and control its thickness, so it will not move with the conveyor belt 7.

[0039] A screening mechanism 2 is provided inside the box 1 and above the permanent magnet drum 4, and a guide plate 3 fixed to the inner wall of the box 1 is provided below the screening mechanism 2.

[0040] The screening mechanism 2 includes two screen plates. The upper screen plate has a larger aperture, which can intercept welding slag or lumps in the flux. The lower screen plate has a smaller aperture, which can screen out oxidized dust and broken particles in the flux. A vibrating motor is installed below the lower screen plate, and a vertical rod is installed between the two screen plates. Therefore, the vibration force can be transmitted to both screen plates at the same time, which promotes the screening efficiency of the flux.

[0041] An adsorption shell 5 is provided on one side of the box 1, and an adsorption tube is connected to the outside of the adsorption shell 5. A gas separation mechanism 6 is provided on one side of the box 1 and below the conveyor belt 7.

[0042] The air separation mechanism 6 is a fan embedded in the inner wall of the housing 1. Two housings are located at the lower inner part of the housing 1, such as... Figure 2 As shown, the lower part of the box 1 and the left side is the impurity collection shell, and the other shell with a guide tube connected to the bottom is the qualified flux collection shell. When the flux falls down from the end of the conveyor belt 7, the gas separation mechanism 6 will blow the light impurities in the falling flux into the shell located on the lower part of the box 1 and the left side, while the heavier qualified flux will fall vertically into the collection shell directly below.

[0043] Working Principle: In practical use, the operator first places the flux in the housing 1. The flux passes through the upper screen of the screening mechanism 2, which intercepts large particles of impurities. The lower screen removes fine powder particles from the flux. After screening, the flux falls onto the surface of the conveyor belt 7 via the guide plate 3. The flux then enters the layered shell 801 via the conveyor belt 7. Due to the large space inside the inlet of the layered shell 801, the flux pile can be leveled. When the flux pile enters the outlet space, the height of this space is lower, thus reducing the thickness of the flux pile. When the flux pile contacts the shovel plate 803, it is lifted by the inclined shovel plate 803 and falls back onto the surface of the conveyor belt 7. This step... The flux can be flipped over and kept in a loose state. When the flux is conveyed from the layered shell 801 to the area below the permanent magnet drum 4 by the conveyor belt 7, some substances in the flux will be adsorbed onto the surface of the permanent magnet drum 4 and carried upward. When the impurities are carried by the permanent magnet drum 4 to the position of the adsorption shell 5, the attraction at this point just disappears, and the impurities will fall downward and be adsorbed outward by the adsorption shell 5. As for the flux after impurity removal, when it is conveyed to the end by the conveyor belt 7, it will fall downward. At this time, the air separation mechanism 6 will blow the light impurities in the falling flux into the shell located on the lower left side of the box 1, while the heavier qualified flux will fall vertically into the collection shell directly below. Thus, the overall screening and impurity removal operation of the flux is completed.

[0044] It should be noted that the conveyor belt 7, vibrating motor, permanent magnet drum 4, and blower of air separation mechanism 6 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the power supply for the conveyor belt 7, vibrating motor, permanent magnet drum 4, and blower of air separation mechanism 6 is all built-in power supply. Furthermore, the specific operating principles and usage steps of the conveyor belt 7, vibrating motor, permanent magnet drum 4, and blower of air separation mechanism 6 can be found on the webpage, and will not be elaborated here.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
