An adsorption device for a paper printing machine

Abstract

This utility model discloses an adsorption device for a paper printing machine, relating to the field of paper printing technology. It includes a control cabinet, a work cabinet on one side of the control cabinet, and a control panel fixedly connected to the top of the control cabinet. The top of the work cabinet has an adsorption structure. This utility model utilizes an electric telescopic rod to drive a stabilizing block, causing the stabilizing block to move a displacement rod in an arc within a limiting groove. Simultaneously, as the displacement rod moves, it uses suction cups at the bottom of the work block to adhere to the paper. A compressor then generates suction force on the suction cups, inserting one side of the paper onto the opposite side of the flattening rod and the conveyor belt for flattening, before finally ejecting it. This avoids the problems of uneven suction and inability to flatten in most devices, enabling the device to stably adsorb a sheet of paper and place it on the top surface of the conveyor belt for flattening, ensuring the flatness of the paper while improving the stability of the adsorption.

Description

Technical Field

[0001] This utility model relates to the field of paper printing technology, and in particular to an adsorption device for a paper printing machine. Background Technology

[0002] Adsorption devices for paper printing presses are key auxiliary equipment used to ensure a smooth printing process and improve printing quality. They are mainly used to adsorb, fix, and transport paper, ensuring the stability and precise positioning of the paper during the printing process.

[0003] The applicant discovered through a search that a Chinese patent, "An Adsorption Device for a Paper Printing Machine," with publication number CN215283953U, includes an air pipe with an air inlet connector. Two square boxes are mounted at both ends of the air pipe, and these boxes are mounted on a mounting rod of the printing machine via an installation device. Each square box is equipped with a protective device for adsorbing printing paper during the adsorption process. The protective device includes a square plate slidably connected inside the square box, which is matched to the inner wall of the box. The square plate has a circular hole. This invention, when the suction force is low, increases the adsorption force on the paper to be adsorbed because the aperture of the adsorption tube is smaller than that of the suction cup, making it less likely to fall off. When the suction force is high, the reduced aperture of the air inlet decreases the effective adsorption area of ​​other papers through the paper, creating a protective effect and preventing the adsorption of other papers, thus facilitating the printing operation of the printing machine.

[0004] However, the existing adsorption hole distribution or design is unreasonable, which will cause uneven adsorption force and may result in multiple sheets of paper being picked up at once. At the same time, some adsorption devices do not have a flattening structure during adsorption and conveying, so the edges and corners of the paper are prone to flipping when they are conveyed to the adsorption structure, requiring manual adjustment and reducing printing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an adsorption device for paper printing presses to solve the problems mentioned in the background art, such as uneven adsorption, adsorption of multiple sheets of paper, and the lack of a flattening structure during the conveying process, which easily leads to paper curling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adsorption device for a paper printing machine, comprising a control cabinet, a work cabinet on one side of the control cabinet, and a control panel fixedly connected to the top surface of the control cabinet. The top surface of the work cabinet is provided with an adsorption structure that can stably adsorb and displace paper. The control cabinet has a control structure inside that can control the adsorption structure to produce a displacement effect. The top surface of the work cabinet is provided with a flattening structure that can flatten the paper when adsorption is complete.

[0007] Preferably, the adsorption structure includes a working block, an adsorption cavity, and suction cups. The working block is located on one side of the top surface of the work cabinet, the adsorption cavity is opened inside the working block, and multiple suction cups are located on the bottom surface of the working block, with each suction cup extending into the interior of the adsorption cavity.

[0008] Preferably, the adsorption structure further includes a transmission pipe and a compressor. The transmission pipe is located on the top surface of the working block, and its bottom end extends into the interior of the adsorption chamber. The compressor is fixedly connected to the top surface of the control cabinet.

[0009] Preferably, the end of the transmission tube furthest from the working block is fixedly connected to the compressor.

[0010] Preferably, the control structure includes a working cavity, an electric telescopic rod, and a stabilizing block. The working cavity is located inside the control cabinet, the electric telescopic rod is fixedly connected to the top surface of the working cavity, and the stabilizing block is fixedly connected to the top surface of the electric telescopic rod.

[0011] Preferably, the control structure further includes a displacement rod and a limiting groove. The displacement rod is rotatably connected to the inside of the stabilizing block, and the limiting groove is opened on one side of the control cabinet surface. The displacement rod passes through the inside of the limiting groove and is fixedly connected to the inside of the working block. At the same time, the surface of the displacement rod is slidably connected to the inner wall of the limiting groove.

[0012] Preferably, the flattening structure includes fixing blocks and flattening rods, with two fixing blocks located on the top of the work cabinet and two flattening rods fixedly connected to the top surfaces of the two fixing blocks.

[0013] Preferably, the top surface of the work cabinet is fixedly connected to two mounting blocks, and the bottom surfaces of the two fixed blocks are respectively fixedly connected to the bottom surfaces of the two mounting blocks. Each of the opposite sides of the two mounting blocks is provided with a conveyor net, and a motor is fixedly connected to one side of the surface of the mounting block.

[0014] The technical effects and advantages of this utility model are as follows: This utility model utilizes an electric telescopic rod to drive a stabilizing block to produce a lifting effect, causing the stabilizing block to drive a displacement rod to move in an arc shape inside the limiting groove. At the same time, when the displacement rod moves, it uses the suction cup at the bottom of the working block to adhere to the paper. Simultaneously, the compressor uses the suction cup to generate suction force, inserting one side of the paper into the displacement rod and pressing it flat on the opposite side of the conveyor network, and finally sending it out. This avoids the problems of uneven suction and inability to flatten in most devices, enabling the device to stably adsorb a piece of paper and place it on the top surface of the conveyor network to complete the flattening effect, ensuring the flatness of the paper while improving the stability of adsorption.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1 to 4 As shown, an adsorption device for a paper printing machine according to the first aspect of this utility model includes a control cabinet 1, a work cabinet 2 provided on one side of the control cabinet 1, and a control panel 3 fixedly connected to the top surface of the control cabinet 1. The top surface of the work cabinet 2 is provided with an adsorption structure 4, which can stably adsorb and displace the paper. The control cabinet 1 is provided with a control structure 5, which can control the adsorption structure 4 to produce a displacement effect. The top surface of the work cabinet 2 is provided with a flattening structure 9, which can flatten the paper when the adsorption is completed.

[0022] The technical effects achieved by the above embodiments are as follows: This utility model uses the electric telescopic rod 502 to drive the stabilizing block 503 to produce a lifting effect, causing the stabilizing block 503 to drive the displacement rod 504 to move in an arc shape inside the limiting groove 505. At the same time, when the displacement rod 504 moves, it uses the suction cup 403 at the bottom of the working block 401 to adhere to the paper. At the same time, the compressor 405 uses the suction cup 403 to generate suction force, inserting one side of the paper into the displacement flattening rod 902 and the opposite side of the conveyor network 7 for flattening, and finally sending it out. This avoids the problem of uneven suction force and inability to flatten in most devices, enabling the device to stably adsorb a piece of paper and place it on the top surface of the conveyor network 7 to complete the flattening effect, ensuring the flatness of the paper while improving the stability of adsorption.

[0023] like Figure 1 and Figure 2 As shown, an adsorption device for a paper printing machine includes all the contents of Embodiment 1. In addition, the adsorption structure 4 includes a working block 401, an adsorption chamber 402, and suction cups 403. The working block 401 is located on one side of the top surface of the work cabinet 2. The adsorption chamber 402 is opened inside the working block 401. Multiple suction cups 403 are located on the bottom surface of the working block 401 and extend into the interior of the adsorption chamber 402. The adsorption structure 4 also includes a transmission pipe 404 and a compressor 405. The transmission pipe 404 is located on the top surface of the working block 401, and its bottom end extends into the interior of the adsorption chamber 402. The compressor 405 is fixedly connected to the top surface of the control cabinet 1. The end of the transmission pipe 404 away from the working block 401 is fixedly connected to the compressor 405.

[0024] The technical effect achieved by the above embodiment is as follows: the multiple suction cups 403 provided at the bottom of the working block 401 are attached to one side of the paper. At this time, the compressor 405 starts to work. Through the adsorption of the compressor 405, the air inside the adsorption chamber 402 is extracted through the connection of the transmission pipe 404, so that the multiple suction cups 403 can be adsorbed to the top surface of the paper. When contact adsorption occurs, the suction cups 403 can release the adsorption effect as long as the compressor 405 stops compressing. Example 3

[0025] like Figure 1 and Figure 3As shown, an adsorption device for a paper printing machine includes all the contents of Embodiment 2. In addition, the control structure 5 includes a working cavity 501, an electric telescopic rod 502, and a stabilizing block 503. The working cavity 501 is opened inside the control cabinet 1.

The stabilizing block 503 is fixedly connected to the top surface of the electric telescopic rod 502. The control structure 5 also includes a displacement rod 504 and a limiting groove 505. The displacement rod 504 is rotatably connected to the inside of the stabilizing block 503. The limiting groove 505 is opened on one side of the surface of the control cabinet 1. The displacement rod 504 passes through the inside of the limiting groove 505 and is fixedly connected to the inside of the working block 401. At the same time, the surface of the displacement rod 504 is slidably connected to the inner wall of the limiting groove 505.

[0026] The technical effect achieved by the above embodiment is as follows: when the working block 401 has finished adsorbing the paper and is moving the paper, it is only necessary to use the electric telescopic rod 502 to drive the top stabilizing block 503 to produce a lifting effect. At that time, the displacement rod 504 rotatably connected inside the stabilizing block 503 can move up and down inside the limiting groove 505, and finally drive the working block 401 to produce a displacement effect. Example 4

[0027] like Figure 1 and Figure 4 As shown, an adsorption device for a paper printing machine includes all the contents of Embodiment 3.

The two fixing blocks 901 are located on the top of the work cabinet 2, and the two flattening rods 902 are fixedly connected to the top surface of the two fixing blocks 901.

[0028] The technical effect achieved by the above embodiment is as follows: when the paper moves, the flattening rod 902 can use the effect of the moving conveyor 7 to make the paper on the top surface of the displacement conveyor 7 move, and the flattening rod 902 can flatten the paper. Example 5
