Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing machine technology, specifically to a screen printing machine feeding device. Background Technology
[0002] The full name of a screen printing machine is screen printing plate. It is a type of printing machine that uses a screen printing plate to apply ink. Screen printing machines can print on flat and curved substrates. The process involves placing the substrate on a printing platform, engraving the pattern to be printed onto the printing plate, pouring ink onto the printing plate, and then using a squeegee to spread the pattern onto the substrate. During the operation of a screen printing machine, a feeding device is needed to transport the substrate. Some existing screen printing machines have feeding devices that can clean the surface of the substrate during the feeding process, but manual pulling by the operator is required to ensure the transport of the substrate, and the device cannot limit the movement of the substrate, which affects the printing effect. Utility Model Content
[0003] In view of this, the present invention provides a feeding device for a screen printing machine, which not only facilitates the conveying of the substrate, but also limits the movement of the substrate, thus ensuring the printing effect of the substrate.
[0004] To solve the above-mentioned technical problems, this utility model provides a feeding device for a screen printing machine, including a feeding box with a placement plate inside. A first motor is located at the front end of the feeding box, and a rotating rod is connected to the output end of the first motor. A rotating roller is mounted on the rotating rod. Two symmetrical rotating shafts are rotatably connected to the left side of the inside of the feeding box, and each rotating shaft is equipped with a conveyor roller. The two conveyor rollers are connected by a conveyor belt. The rotating rod is connected to the rotating shaft on the right side by a pulley. Two first electric push rods are symmetrically arranged on the outer surface of the feeding box. The extension and retraction of the first electric push rods... The end is connected to a limiting plate. When feeding the substrate, the operator can place the substrate on the conveyor belt. Then, the operator can start the first motor, which causes the rotating rod to drive the rotating roller to rotate. Under the transmission of the belt pulley, the rotating shaft can rotate in the same direction, conveying the substrate on the conveyor belt to the right. The operator can start the first electric push rod according to the width of the substrate to adjust the distance between the limiting plates, and limit the moving substrate to ensure that it can be aligned when it moves to the screen printing machine, which facilitates printing.
[0005] The front end of the feeding box has a groove, and the pulley is located inside the groove.
[0006] The upper surfaces of the placement plate, conveyor belt, and rollers are all located on the same horizontal plane, ensuring the planar movement of the substrate during the feeding process.
[0007] A second motor is installed at the front end of the feeding box. The output end of the second motor is connected to a feeding roller. The feeding roller is located at the right slot of the placement plate. After the substrate is separated from the rotating roller and the pressure roller, the feeding roller can ensure the conveying of the substrate.
[0008] The feed box is equipped with a guide plate located between the conveyor belt and the roller to prevent the printed material from deviating when passing through the gap between the conveyor belt and the roller.
[0009] A second electric push rod is installed at the top of the feeding box. The telescopic end of the second electric push rod is connected to a connecting frame. A pressure roller is rotatably connected inside the connecting frame. The pressure roller corresponds to the rotating roller. Two symmetrical sliding grooves are opened inside the feeding box. A slider is slidably connected in each groove. The slider is connected to the connecting frame. When the substrate moves to the top of the rotating roller, the operator can activate the second electric push rod, which causes the connecting frame to drive the pressure roller to move down, so that the pressure roller contacts the top of the substrate. At this time, the substrate is located between the pressure roller and the rotating roller. The pressing action ensures the effective conveying of the substrate.
[0010] The feed box is equipped with a fixed brush head inside, and a third electric push rod is located at the top of the feed box. The telescopic end of the third electric push rod is connected to a movable brush head. The fixed brush head cleans the bottom of the substrate, and then the operator can activate the third electric push rod to move the movable brush head down to clean the top of the substrate, ensuring the printing effect of the substrate.
[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects of a screen printing machine feeding device:
[0012] 1. When using this utility model, it not only facilitates the conveying of the printing substrate, but also limits the movement of the printing substrate, thus ensuring the printing effect of the substrate.
[0013] 2. When using this utility model, the inside of the feeding box is equipped with a guide plate, which is located between the conveyor belt and the rotating roller to prevent the printed material from deviating when passing through the gap between the conveyor belt and the rotating roller.
[0014] 3. When this utility model is in use, when the substrate moves to the upper side of the rotating roller, the operator can activate the second electric push rod, which causes the connecting frame to drive the pressure roller to move down, so that the pressure roller contacts the upper side of the substrate. At this time, the substrate is located between the pressure roller and the rotating roller, and the conveying effect of the substrate is ensured by squeezing.
[0015] 4. When using this utility model, the fixed brush head will clean the bottom of the substrate. Then, the operator can activate the third electric push rod to move the moving brush head down to clean the upper side of the substrate, thus ensuring the printing effect of the substrate.

When feeding the substrate, the operator can place the substrate on the conveyor belt 306. Then, the operator can start the first motor 301, which causes the rotating rod 302 to drive the rotating roller 303 to rotate. Under the transmission action of the pulley 308, the rotating shaft 304 can be driven to rotate in the same direction, conveying the substrate on the conveyor belt 306 to the right. The operator can start the first electric push rod 401 according to the width of the substrate to adjust the distance between the limiting plates 402, and limit the moving substrate to ensure that it can be aligned when it moves to the screen printing machine, which facilitates printing. The upper surfaces of the placement plate 200, the conveyor belt 306 and the rotating roller 303 are all on the same horizontal plane, ensuring the planar movement of the substrate during feeding.
[0024] According to another embodiment of the present invention, such as Figure 1-4As shown, a second motor 309 is provided at the front end of the feeding box 100. The output end of the second motor 309 is connected to a feeding roller 310. The feeding roller 310 is located at the right groove of the placement plate 200. After the substrate is separated from the rotating roller 303 and the pressure roller 603, the feeding roller 310 can ensure the conveying of the substrate. A guide plate 500 is provided inside the feeding box 100. The guide plate 500 is located between the conveyor belt 306 and the rotating roller 303 to prevent the substrate from deviating when passing through the gap between the conveyor belt 306 and the rotating roller 303. A second electric push rod 601 is provided at the upper end of the feeding box 100. The telescopic end of the second electric push rod 601 is connected to a connecting frame 602.

[0025] The method of using this utility model is as follows: When feeding the substrate, the operator can place the substrate on the conveyor belt 306. Then, the operator can start the first motor 301, causing the rotating rod 302 to drive the rotating roller 303 to rotate. Under the transmission action of the pulley 308, the rotating shaft 304 can be driven to rotate in the same direction, conveying the substrate on the conveyor belt 306 to the right. When the substrate moves to the upper side of the rotating roller 303, the operator can start the second electric push rod 601, causing the connecting frame 602 to drive the pressure roller 603 to move down, so that the pressure roller 603 contacts the upper side of the substrate. At this time, the substrate is located between the pressure roller 603 and the rotating roller 303, and the pressing ensures the substrate is printed. After the material is conveyed, the fixed brush head 701 cleans the bottom of the substrate. Then, the operator can activate the third electric push rod 702 to move the moving brush head 703 down to clean the upper side of the substrate, ensuring the printing effect. The operator can activate the first electric push rod 401 according to the width of the substrate to adjust the distance between the limiting plates 402, limiting the moving substrate and ensuring that it can be aligned when it moves to the screen printing machine, facilitating printing. This utility model not only facilitates the conveying of the substrate but also limits the moving substrate, ensuring the printing effect.
