Description

Technical Field

[0001] This invention relates to the field of offset printing technology, specifically to a powder spraying control device for an offset printing paper receiving machine. Background Technology

[0002] Offset printing paper receiving machine powder spraying refers to spraying powder onto the surface of printed materials to promote ink drying and increase the surface strength of the paper. During the offset printing process, powder spraying is required on the printed paper. This powder spraying operation utilizes a powder spraying control device for the offset printing paper receiving machine. The "A Printing Machine and Method for Spraying Coating Paper" disclosed in authorization announcement number "CN105564027A" has solved the problem that traditional production methods use purchased finished tin-lead alloy films, resulting in high costs and waste during production, leading to high production costs for tin paper. Further research revealed that the "Electronic..." disclosed in authorization announcement number "CN101817254A"... The "pneumatic powder spraying device" effectively solves the technical drawbacks of the inability to effectively control the direction and amount of powder spraying, resulting in uneven powder spraying and ineffective control of the spraying range. However, in actual use, similar powder spraying control devices still have many defects, such as: too much powder is sprayed during printing, which cannot be selectively controlled; too much powder will accumulate on the paper surface, while too little powder will cause the paper to stick together, producing defective products and increasing costs. At the same time, after long-term use, a lot of dust tends to accumulate on the top. When the dust is affected by airflow, it is easy for it to float up, which can cause the dust to fall and affect the powder spraying operation, and easily pollute the air in the working environment. Therefore, it is necessary to design a powder spraying control device for offset printing paper receiving machines. Summary of the Invention

[0003] The purpose of this invention is to provide a powder spraying control device for offset printing paper receiving machines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a powder spraying control device for an offset printing paper receiving machine, comprising a support plate, a track plate, a support roller, and a fixing frame. A first conveying roller is rotatably mounted on the inner side of the support plate, and a second conveying roller is rotatably mounted on the inner side of the support plate on one side of the first conveying roller. Paper is rotatably connected to the inner sides of the first and second conveying rollers. A track plate is fixedly mounted on the inner side of the support plate at the top of the support roller, and a movable frame is movably mounted on the outer side of the track plate. A powder spraying head is fixedly mounted on one side of the movable frame. A fixing block is fixedly connected to the inner side of the support plate at the top of the track plate, and an adjusting frame is slidably mounted on the inner side of the fixing block. A second fixing plate is fixedly mounted on the top of the support plate via a first fixing plate, and a fan is fixedly connected to the inner side of the second fixing plate. A fixing frame is fixedly mounted on the rear end of the second fixing plate.

[0005] By passing the offset-printed paper between the second conveyor rollers and then through the first conveyor roller, and by feeding powder into the corrugated pipe, the paper can be easily fed and collected by rotating the first and second conveyor rollers. The powder can be fed into the spray nozzle, and by moving the movable frame back and forth along the track plate, the powder can be sprayed out through the spray nozzle, facilitating the powder spraying operation. By pulling the adjusting frame left and right along the fixed block, the different sized holes on the inner side of the adjusting frame correspond to the channels inside the fixed block, allowing for easy adjustment and control of the amount of powder fed into the spray nozzle. When a large amount of dust accumulates on the top of the first fixed plate, the fan can be activated to blow the accumulated dust into the fixed frame for collection, allowing for periodic cleaning of the dust falling from the top and preventing a single drop from affecting the powder spraying operation.

[0006] Preferably, a first motor is fixedly mounted on the front end of the support plate, and the output end of the first motor is fixedly connected to the first conveyor roller and the second conveyor roller respectively. Starting the first motor can drive the first conveyor roller and the second conveyor roller to rotate.

[0007] Preferably, a support roller corresponding to the paper is rotatably mounted on the inner side of the support plate on one side of the second conveying roller. The support roller is located on top of the first conveying roller, and a baffle frame is fixedly mounted on the inner side of the support plate on one side of the support roller. The support roller can provide rolling support for the paper during conveying, and the baffle frame can block the powder during spraying, preventing powder from splashing.

[0008] Preferably, a movable plate is movably mounted on the inner side of the second fixed plate at the rear end of the fan, and the movable plate is movably connected to the second fixed plate through a shaft hole. By controlling the fan to start, the bottom of the movable plate can be blown backward along the shaft hole, so that the movable plate guides the airflow blown by the fan.

[0009] Preferably, a rack is fixedly installed on the top of the track plate, and a gear disk that meshes with the rack is rotatably installed on the inner side of the movable frame. By driving the gear disk to rotate, and utilizing the meshing between the rack and the gear disk, the gear disk can roll along the rack, thereby driving the movable frame to move back and forth along the track plate.

[0010] Preferably, a second motor corresponding to the gear disk is fixedly installed on one side of the movable frame, and a support wheel corresponding to the track plate is rotatably installed on the inner side of the movable frame. Starting the second motor drives the gear disk to rotate, and the support wheel provides rolling support to the track plate, improving the stability of the movable frame's forward and backward movement.

[0011] Preferably, the fixed block and the powder spraying head are connected by a corrugated pipe, and a docking seat connected to the corrugated pipe is fixedly installed on the top of the fixed block. By connecting the docking seat to an external powder conveying pipeline, powder can be conveyed into the corrugated pipe, and then into the powder spraying head through the corrugated pipe, without affecting the movement of the movable frame.

[0012] Preferably, an intercepting net is fixedly installed on the inner side of the fixing frame, and a collection hopper is slidably installed on the inner side of the fixing frame at the bottom of the intercepting net. By using the intercepting net to intercept dust, the dust can fall into the collection hopper for collection.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting up a fixed block, an adjusting frame and a powder spraying head, the powder can be conveyed to the powder spraying head for spraying by connecting the docking seat with the powder conveying pipe, which facilitates the powder spraying operation. By pulling the adjusting frame to move left and right along the fixed block, the different sizes of holes on the inner side of the adjusting frame correspond to the channels inside the fixed block, which can easily adjust and control the amount of powder conveyed to the powder spraying head.

[0015] 2. By setting up a movable plate, a fixed frame, and a collection hopper, when a lot of dust accumulates on the top of the first fixed plate, the fan can be started to blow the bottom of the movable plate backward, so that the movable plate guides the airflow blown by the fan. The airflow blows the dust accumulated on the top of the first fixed plate towards the inside of the fixed frame, where the dust is intercepted by the interception net and falls into the collection hopper for collection. The dust falling from the top can be cleaned periodically to prevent a single drop from affecting the powder spraying operation. Attached Figure Description

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the offset printing paper receiving machine powder spraying control device proposed in this invention includes a support plate 1, a track plate 4, a support roller 104 and a fixed frame 6. A first conveying roller 103 is rotatably installed on the inner side of the support plate 1. A second conveying roller 105 is rotatably installed on the inner side of the support plate 1 on one side of the first conveying roller 103. Paper 3 is rotatably connected to the inner side of the first conveying roller 103 and the second conveying roller 105. A track plate 4 is fixedly installed on the inner side of the support plate 1 at the top of the support roller 104. A movable frame 401 is movably installed on the outer side of the track plate 4. A powder spraying head 405 is fixedly installed on one side of the movable frame 401.

[0029] A fixing block 7 is fixedly connected to the inner side of the support plate 1 at the top of the track plate 4. An adjusting frame 702 is slidably installed on the inner side of the fixing block 7. A second fixing plate 5 is fixedly installed on the top of the support plate 1 through the first fixing plate 2. A fan 501 is fixedly connected to the inner side of the second fixing plate 5. A fixing frame 6 is fixedly installed at the rear end of the second fixing plate 5.

[0030] A support roller 104 corresponding to the paper 3 is rotatably installed on the inner side of the support plate 1 on one side of the second conveying roller 105. The support roller 104 is located on top of the first conveying roller 103. A baffle frame 102 is fixedly installed on the inner side of the support plate 1 on one side of the support roller 104. A movable plate 502 is movably installed on the inner side of the second fixed plate 5 at the rear end of the fan 501. The movable plate 502 and the second fixed plate 5 are movably connected through the shaft hole 503. The fixed block 7 is connected to the powder spraying head 405 through the corrugated pipe 703. A docking seat 701 connected to the corrugated pipe 703 is fixedly installed on the top of the fixed block 7. An intercepting net 601 is fixedly installed on the inner side of the fixed frame 6. A collecting hopper 602 is slidably installed on the inner side of the fixed frame 6 at the bottom of the intercepting net 601.

[0031] The working principle of the offset printing paper receiving machine powder spraying control device based on Embodiment 1 is as follows: by passing the offset printed paper 3 through the second conveying roller 105, then passing the paper 3 through the top of the support roller 104, and finally passing the paper 3 through the first conveying roller 103, the powder can be conveyed into the corrugated pipe 703 by connecting the docking seat 701 with the external powder conveying pipe.

[0032] By driving the first conveying roller 103 and the second conveying roller 105 to rotate, the paper 3 can be easily conveyed and collected. The powder can be conveyed to the powder spraying head 405 through the corrugated pipe 703 without affecting the movement of the movable frame 401. By driving the movable frame 401 to move back and forth along the track plate 4, and then spraying the powder through the powder spraying head 405, the paper 3 can be easily powdered. By pulling the adjusting frame 702 to move left and right along the fixed block 7, the holes of different sizes on the inner side of the adjusting frame 702 correspond to the channels inside the fixed block 7, and the amount of powder conveyed to the powder spraying head 405 can be easily adjusted and controlled.

[0033] The support roller 104 provides rolling support for the paper 3 during transport, while the baffle frame 102 blocks the powder during spraying to prevent powder from splashing. When a lot of dust accumulates on the top of the first fixed plate 2, the fan 501 is activated, causing the bottom of the movable plate 502 to flip backward along the shaft hole 503. This guides the airflow from the fan 501, causing the airflow to blow the dust accumulated on the top of the first fixed plate 2 towards the inside of the fixed frame 6. The intercepting net 601 intercepts the dust, allowing it to fall into the collection hopper 602 for collection. The dust that falls from the top can be cleaned periodically to prevent a single drop from affecting the powder spraying operation.

[0036] In this embodiment, as Figure 1 As shown, starting the first motor 101 can drive the first conveyor roller 103 and the second conveyor roller 105 to rotate; as Figure 5 As shown, by driving the gear disk 406 to rotate, and utilizing the meshing of the rack 402 with the gear disk 406, the gear disk 406 can roll along the rack 402, which can drive the movable frame 401 to move back and forth along the track plate 4; as Figure 5As shown, starting the second motor 404 can drive the gear disk 406 to rotate, and the support wheel 403 can provide rolling support with the track plate 4, thereby improving the stability of the movable frame 401 moving back and forth.
