Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a developing roller spraying device. Background Art

[0002] During the manufacturing process of the developing roller, it is necessary to spray a layer of conductive paint on the rubber roller of the roller core. At present, the spraying device generally uses a top cup to drive the roller core to rotate, and the nozzle moves along the axis of the roller core and sprays the conductive paint toward the outer cylindrical surface of the rubber roller, so that the outer cylindrical surface of the rubber roller is sprayed with a layer of conductive paint. After working for a period of time, a thick layer of conductive paint will be coated on the top cup. In order to prevent the conductive paint on the top cup from sticking to the roller core and the end face of the rubber roller, it is necessary to stop the machine and manually replace or clean the top cup, which is a lot of work and affects the efficiency of the developing roller spraying.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figures 1 to 4The present invention discloses a developing roller spraying device, comprising a spraying positioning mechanism 200, a cleaning mechanism 300 and a spraying mechanism 400. The spraying positioning mechanism 200 comprises a rotating frame, a pair of first top cups 210 and a pair of second top cups 220. The pair of first top cups 210 and the pair of second top cups 220 are both used to clamp the developing roller. The rotating frames, the pair of first top cups 210 and the pair of second top cups 220 are on the same plane. The rotating frames drive the pair of first top cups 210 and the pair of second top cups 220 to rotate, so that the pair of first top cups 210 and the pair of second top cups 220 are rotated. The cup 220 is alternately located at the developing roller spraying station and the cleaning station; the cleaning mechanism 300 includes a heating component 310 and a cleaning brush 320 both of which can move left and right, the heating component 310 is used to heat the conductive coating on a pair of first top cups 210 / a pair of second top cups 220 located at the cleaning station, and the cleaning brush 320 is used to remove the conductive coating on the pair of first top cups 210 / a pair of second top cups 220 after being heated; the spraying mechanism 400 is used to spray the conductive coating on the developing roller on the pair of first top cups 210 / a pair of second top cups 220 located at the developing roller spraying station.

[0037] The developing roller spraying device is provided with a developing roller spraying station and a cleaning station. When the rotating frame drives a pair of first top cups 210 and a pair of second top cups 220 to rotate, the pair of first top cups 210 and the pair of second top cups 220 can be alternately placed at the developing roller spraying station and the cleaning station.

[0038] When a pair of first top cups 210 clamp the developing roller and are in the developing roller spraying station, and a pair of second top cups 220 are in the cleaning station, the spraying mechanism 400 sprays the developing roller on the pair of first top cups 210 in the developing roller spraying station with conductive paint, the heating component 310 of the cleaning mechanism 300 heats the conductive paint on the pair of second top cups 220 in the cleaning station, and then the cleaning brush 320 removes the conductive paint on the heated pair of second top cups 220. When a pair of second top cups 220 clamp the developing roller and are in the developing roller spraying station, and a pair of first top cups 210 are in the cleaning station, the spraying mechanism 400 sprays the conductive paint on the developing roller on the pair of second top cups 220 in the developing roller spraying station, the heating component 310 of the cleaning mechanism 300 heats the conductive paint on the pair of first top cups 210 in the cleaning station, and then the cleaning brush 320 removes the conductive paint on the heated pair of first top cups 210.

[0039] When a certain amount of conductive paint is adhered to the first top cup 210 or the second top cup 220, the pair of first top cups 210 and the pair of second top cups 220 are driven to rotate by the rotating frame, so that the first top cup 210 or the second top cup 220 adhered to a certain amount of conductive paint rotates to the cleaning position, and the first top cup 210 or the second top cup 220 corresponds to the position of the cleaning mechanism 300, and the second top cup 220 or the first top cup 210 originally in the cleaning position rotates to the developing roller spraying position and corresponds to the position of the spraying mechanism 400. The cleaning mechanism 300 and the spraying mechanism 400 work at the same time to ensure that there is always a developing roller spraying the conductive paint, and there is no need to stop the machine to remove the conductive paint from the top cup, thereby improving the working efficiency of spraying the developing roller, and there is no need to manually remove the conductive paint on the top cup, thereby reducing the labor of workers and reducing labor costs.

[0040] The conductive coating on the first top cup 210 / the second top cup 220 is first heated to soften the conductive coating, and then the conductive coating on the first top cup 210 / the second top cup 220 is removed with a cleaning brush 320 , thereby improving the efficiency and effect of removing the conductive coating.

[0041] Reference Figure 1 and Figure 4 In some of the embodiments, the developing roller spraying device further includes a loading conveyor 500 and a unloading conveyor 600 distributed up and down, and a loading support assembly 510 capable of tilting and lifting is provided at the end of the loading conveyor 500, and the loading support assembly 510 is used to push the developing roller at the end of the loading conveyor 500 to a pair of first top cups 210 / a pair of second top cups 220 at the developing roller spraying station, and a unloading support assembly 610 capable of vertically lifting is provided at the head end of the unloading conveyor 600, and the unloading support assembly 610 is used to connect the developing roller on the pair of first top cups 210 / a pair of second top cups 220 at the developing roller spraying station to the head end of the unloading conveyor 600.

[0042] Initially, the end of the feeding conveyor 500 and the feeding support assembly 510 are at the same height position, and the feeding conveyor 500 conveys the developing roller to be sprayed with the conductive paint to the feeding support assembly 510, and then the feeding support assembly 510 carries the developing roller to be sprayed with the conductive paint and rises obliquely to the developing roller spraying station, and the two ends of the developing roller to be sprayed with the conductive paint are clamped or supported by a pair of first top cups 210 / a pair of second top cups 220, and then the feeding support assembly 510 is reset. Then the spraying mechanism 400 sprays the conductive paint on the developing roller to be sprayed with the conductive paint, and then the unloading support assembly 610 rises to the developing roller spraying station, and the unloading support assembly 610 receives the developing roller sprayed with the conductive paint from a pair of first top cups 210 / a pair of second top cups 220, and the unloading support assembly 610 carries the developing roller sprayed with the conductive paint and descends to the height of the first section of the unloading conveyor 600, and finally the developing roller sprayed with the conductive paint is received by the unloading conveyor 600.

[0043] It can be understood that the length direction of the loading conveyor 500 and the unloading conveyor 600 are both front-to-back directions. The loading conveyor 500 is used to convey the developing roller to be sprayed with conductive paint from front to back, and the unloading conveyor 600 is used to convey the developing roller sprayed with conductive paint from back to front. The loading conveyor 500 and the unloading conveyor 600 are both arranged in the front and lower part of the spray positioning mechanism 200, and the end of the loading conveyor 500 is located in the front and lower part of the developing roller spraying station, and the head end of the unloading conveyor 600 is located below the developing roller spraying station.

[0044] Reference Figure 4 In some embodiments, the developing roller spraying device also includes a linear drive mechanism 520 and a first lifting drive mechanism 620. The moving direction of the output end of the linear drive mechanism 520 is tilted upward and backward. The output end of the linear drive mechanism 520 is connected to the loading support assembly 510. The linear drive mechanism 520 drives the loading support assembly 510 to rise and fall along an inclined trajectory. The first lifting drive mechanism 620 is connected to the unloading support assembly 610. The first lifting drive mechanism 620 drives the unloading support assembly 610 to move in the up and down directions. The loading support assembly 510 and the unloading support assembly 610 work at different times, and the loading support assembly 510 and the unloading support assembly 610 are initially in different positions, which can avoid interference between the loading support assembly 510 and the unloading support assembly 610.

[0045] It can be understood that the linear drive mechanism 520 is disposed below the unloading conveyor 600, and the output end of the linear drive mechanism 520 is connected to the loading support assembly 510 through the U-shaped frame 530. When the U-shaped frame 530 rises obliquely backward, the unloading conveyor 600 is located between the two side walls of the U-shaped frame 530. The inclination angle of the linear drive mechanism 520 is adjustable, so as to ensure that the linear drive mechanism 520 can accurately convey the developing roller to be sprayed with the conductive coating to the pair of first top cups 210 / a pair of second top cups 220 of the developing roller spraying station.

[0046] The material loading support assembly 510 includes two vertical plates distributed on the left and right, and the upper ends of the vertical plates are provided with V-shaped grooves, and the inner groove wall of the V-shaped groove is used to support the end of the developing roller. The structure of the material loading support assembly 610 is the same as or similar to that of the material loading support assembly 510, and redundant introduction is not made here. The material loading conveyor 500 and the material loading conveyor 600 are common components in the market, and redundant introduction is not made here either.

[0047] Reference Figures 1 to 3 In some embodiments thereof, the spray positioning mechanism 200 further includes a first rotation drive mechanism 240 and a first left sliding plate 250 and a first right sliding plate 260 both of which can move in the left and right directions. The rotating frame includes a left rotating plate 270 and a right rotating plate 280. The left rotating plate 270 and the right rotating plate 280 have the same rotation axis. The left rotating plate 270 and the right rotating plate 280 are respectively rotatably disposed on the first left sliding plate 250 and the first right sliding plate 260. A pair of first top cups 210 are respectively disposed on the left rotating plate 270 and the right rotating plate 280. A pair of second top cups 220 are respectively disposed on the left rotating plate 270 and the right rotating plate 280. The first rotation drive mechanism 240 is transmission-connected to the left rotating plate 270 and the right rotating plate 280 to drive the left rotating plate 270 and the right rotating plate 280 to rotate synchronously.

[0048] Since the first left sliding plate 250 and the first right sliding plate 260 can both move in the left-right direction, the first left sliding plate 250 and the first right sliding plate 260 can move closer to or farther from each other. When the first left sliding plate 250 and the first right sliding plate 260 are driven to move away from each other, the left rotating plate 270 and the right rotating plate 280 also move away from each other, so that the pair of first top cups 210 move away from each other, and the pair of second top cups 220 move away from each other. At this time, a developing roller can be placed between the pair of first top cups 210 / a pair of second top cups 220, and the two ends of the developing roller correspond to the pair of first top cups 210 / a pair of second top cups 220 respectively, and then the first left sliding plate 250 and the first right sliding plate 260 are driven to move closer to each other, and the pair of first top cups 210 / a pair of second top cups 220 can clamp or support the developing roller. The first left sliding plate 250 and the first right sliding plate 260 first move away from each other and then move closer to each other to complete the loading of the developing roller to a pair of first top cups 210 / a pair of second top cups 220. The first left sliding plate 250 and the first right sliding plate 260 first move closer to each other and then move away from each other to complete the unloading of the developing roller to a pair of first top cups 210 / a pair of second top cups 220.

[0049] The spray positioning mechanism 200 also includes a second rotation drive mechanism 230, which is transmission-connected to a pair of first top cups 210 and a pair of second top cups 220. The second rotation drive mechanism 230 drives the pair of first top cups 210 and the pair of second top cups 220 to rotate. The pair of first top cups 210 can carry the developing rollers thereon to rotate, and the pair of second top cups 220 can carry the developing rollers thereon to rotate.

[0050] Reference Figure 2 In some embodiments, a second left sliding plate 251 capable of moving in the left-right direction is provided on the first left sliding plate 250, a second right sliding plate 261 capable of moving in the left-right direction is provided on the first right sliding plate 260, two cleaning brushes 320 are spiral-shaped, and the two cleaning brushes 320 are respectively provided on the second left sliding plate 251 and the second right sliding plate 261. The two cleaning brushes 320 are used to be put on a pair of first top cups 210 / a pair of second top cups 220 to remove the conductive coating on the pair of first top cups 210 / a pair of second top cups 220.

[0051] The second left sliding plate 251 carries a cleaning brush 320 to slide on the first left sliding plate 250 in the left-right direction, and the cleaning brush 320 can move left-right relative to the first top cup 210 / the second top cup 220 on the left rotating plate 270 . When a cleaning brush 320 moves leftward relative to the first top cup 210 / second top cup 220 on the left rotating plate 270, the cleaning brush 320 can be sleeved on the first top cup 210 / second top cup 220 on the left rotating plate 270. At this time, the first top cup 210 / second top cup 220 rotates, and the cleaning brush 320 can brush off the conductive paint on the first top cup 210 / second top cup 220. When a cleaning brush 320 moves rightward relative to the first top cup 210 / second top cup 220 on the left rotating plate 270, the cleaning brush 320 is separated from the first top cup 210 / second top cup 220 on the left rotating plate 270, so as to avoid interference between the cleaning brush 320 and the first top cup 210 / second top cup 220 on the left rotating plate 270, and also to avoid interference between the cleaning brush 320 and the rotation of the left rotating plate 270.

[0052] Similarly, the second right sliding plate 261 carries another cleaning brush 320 to slide on the first right sliding plate 260 in the left-right direction, and the other cleaning brush 320 moves left-right relative to the first top cup 210 / second top cup 220 on the right rotating plate 280 . When the other cleaning brush 320 moves rightward relative to the first top cup 210 / second top cup 220 on the right rotating plate 280, the other cleaning brush 320 can be sleeved on the first top cup 210 / second top cup 220 on the right rotating plate 280. At this time, the first top cup 210 / second top cup 220 rotates, and the other cleaning brush 320 can brush off the conductive paint on the first top cup 210 / second top cup 220. When the other cleaning brush 320 moves leftward relative to the first top cup 210 / second top cup 220 on the right rotating plate 280, the other cleaning brush 320 is separated from the first top cup 210 / second top cup 220 on the right rotating plate 280, so as to avoid interference between the other cleaning brush 320 and the first top cup 210 / second top cup 220 on the right rotating plate 280, and also to avoid interference between the other cleaning brush 320 and the rotation of the right rotating plate 280.

[0053] It can be understood that the cleaning brush 320 is a wire brush.

[0054] Reference Figure 2 In some embodiments, there are two heating components 310, and the heating components 310 are U-shaped. The second left sliding plate 251 and the second right sliding plate 261 are both hinged with swing arms 700. The swing ends of the two swing arms 700 are respectively connected to the two heating components 310, and the two heating components 310 are respectively located on the left and right sides of the two cleaning brushes 320, that is, one heating component 310 is located on the left side of the left cleaning brush 320, and the other heating component 310 is located on the right side of the right cleaning brush 320.

[0055] Since the heating assembly 310 is U-shaped, the heating assembly 310 can be swung so that the first top cup 210 / the second top cup 220 enters the opening of the heating assembly 310 .

[0056] The two swing arms 700 can drive the two heating components 310 to be respectively mounted on a pair of first top cups 210 / a pair of second top cups 220. The first left sliding plate 250 and the first right sliding plate 260 are both provided with a toggle block 800. The two swing arms 700 can respectively abut against the two toggle blocks 800 to make the two swing arms 700 swing forward or backward, so as to make the two heating components 310 respectively stay away from the pair of first top cups 210 / a pair of second top cups 220.

[0057] The second left sliding plate 251 carries a cleaning brush 320 and a heating assembly 310 to slide on the first left sliding plate 250 in the left and right directions, and a cleaning brush 320 and a heating assembly 310 can move left and right relative to the first top cup 210 / second top cup 220 on the left rotating plate 270. When a cleaning brush 320 and a heating assembly 310 move leftward relative to the first top cup 210 / second top cup 220 on the left rotating plate 270, a heating assembly 310 is firstly put on the first top cup 210 / second top cup 220 on the left rotating plate 270, and then the second left sliding plate 251 carrying a cleaning brush 320 and a heating assembly 310 stops moving leftward, and a heating assembly 310 heats the conductive coating on the first top cup 210 / second top cup 220 on the left rotating plate 270, and then the second left sliding plate 251 carrying a cleaning brush 320 and a heating assembly 310 continues to move leftward, and the swing arm 700 on the second left sliding plate 251 will abut against the toggle block 800, and the toggle block 800 drives the swing arm 700 to swing forward or backward, thereby driving a The heating component 310 moves away from the first top cup 210 / second top cup 220 on the left rotating plate 270, and then a cleaning brush 320 is put on the first top cup 210 / second top cup 220 on the left rotating plate 270. At this time, the first top cup 210 / second top cup 220 rotates, and the cleaning brush 320 can brush off the conductive paint on the first top cup 210 / second top cup 220. When the second left sliding plate 251 moves right with the cleaning brush 320 and the heating component 310, the cleaning brush 320 and the heating component 310 will move in the opposite direction along the previous trajectory to complete the reset, that is, the cleaning brush 320 and the heating component 310 move to a position where they will not interfere with the first top cup 210 / second top cup 220 on the left rotating plate 270.

[0058] Similarly, the second right sliding plate 261 carries another cleaning brush 320 and another heating component 310 to slide along the left and right directions on the first right sliding plate 260, and the other cleaning brush 320 and the other heating component 310 move left and right relative to the first top cup 210 / second top cup 220 on the right rotating plate 280. When the other cleaning brush 320 and the other heating component 310 move rightward relative to the first top cup 210 / the second top cup 220 on the right rotating plate 280, the other heating component 310 is firstly put on the first top cup 210 / the second top cup 220 on the right rotating plate 280, and then the second right sliding plate 261 carries the other cleaning brush 320 and the other heating component 310 to stop moving rightward, and the other heating component 310 heats the conductive coating on the first top cup 210 / the second top cup 220 on the right rotating plate 280, and then the second right sliding plate 261 carries the other cleaning brush 320 and the other heating component 310 to continue moving rightward, and the swing arm 700 on the second right sliding plate 261 will abut against the toggle block 800, and the toggle block 800 drives the swing arm 700 to swing forward or backward, thereby driving the other The heating component 310 moves away from the first top cup 210 / second top cup 220 on the right rotating plate 280, and then, another cleaning brush 320 is put on the first top cup 210 / second top cup 220 on the right rotating plate 280. At this time, the first top cup 210 / second top cup 220 rotates, and the other cleaning brush 320 can brush off the conductive paint on the first top cup 210 / second top cup 220. When the second right sliding plate 261 carries the other cleaning brush 320 and the other heating component 310 to move to the left, the other cleaning brush 320 and the other heating component 310 will move in the opposite direction along the previous trajectory to complete the reset, that is, the other cleaning brush 320 and the other heating component 310 move to a position where they will not interfere with the first top cup 210 / second top cup 220 on the right rotating plate 280.

[0059] It is understandable that the swing arm 700 faces forward or backward in the opposite direction to the opening of the heating assembly 310. In this embodiment, the lower end of the swing arm 700 is connected to the heating assembly 310, and when the lower end of the swing arm 700 carries the heating assembly 310 and swings forward, the heating assembly 310 is separated from the state of being sheathed in the first top cup 210 / the second top cup 220.
