Description

Technical Field

[0001] This utility model relates to the field of paper printing technology, specifically to an intermittent green paper feeding device for book and magazine production. Background Technology

[0002] The printing press consists of a paper feeding section, a printing section, a slotting section, and a die-cutting section. Currently, the paper feeding section generally adopts a leading-edge feeding process, which uses the leading edge of the cardboard as a reference and uses the paper feeding rollers to periodically accelerate, synchronize, and decelerate, causing the grid on the conveyor belt to lift and drop the corrugated paper.

[0003] Publication number CN213833789U discloses a corrugated paper printing intermittent leading edge feeding device and a corrugated paper printing feeding device. By setting a negative pressure adsorption device to adsorb the corrugated paper, it can ensure that the corrugated paper sticks tightly to the conveyor belt and does not move, while maintaining the integrity of the corrugated paper shape. However, this patent still has the following problems in actual use:

[0004] By using a negative pressure adsorption device to hold the corrugated paper in place, the corrugated paper can be kept firmly against the conveyor belt and its flute shape can be maintained. However, after prolonged use, the negative pressure device needs to be disassembled to clean the dust inside. Currently, most negative pressure devices are installed using bolts and screw holes. When the negative pressure device is connected by bolts and screw holes, tools such as wrenches are needed to loosen the bolts when disassembling it. If the bolts are rusty or overtightened, disassembly may be difficult, especially in some long-used equipment where the bolts and screw holes may become seized. Rust removal and lubrication are required for smooth disassembly, making it quite inconvenient for workers to disassemble the negative pressure device.

[0005] An intermittent green paper feeding device for book and periodical production is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an intermittent green paper feeding device for book and magazine production, to solve the problem mentioned in the background art. Currently, the negative pressure adsorption device is used to adsorb corrugated paper, ensuring that the corrugated paper adheres tightly to the conveyor belt and maintains its integrity. However, after prolonged use, the negative pressure device needs to be disassembled to clean the dust inside. Currently, most negative pressure devices are connected via bolts and screw holes. Disassembling the negative pressure device requires tools such as wrenches to loosen the bolts. If the bolts are rusty or overtightened, disassembly may be difficult, especially in equipment that has been used for a long time, where the bolts and screw holes may become seized, requiring rust removal and lubrication for smooth disassembly. This makes disassembling the negative pressure device inconvenient for workers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an intermittent green paper feeding device for book and periodical production, including a conveying device, wherein a connecting frame is fixedly installed on the bottom surface of the conveying device;

[0008] The surface of the connecting frame is fixedly connected to several partitions, and the surface of the connecting frame is provided with several negative pressure devices. Connecting plates are symmetrically installed on both sides of the negative pressure devices. Fixed frames are fixedly connected to both sides of the top surface of the conveying device, and blocking components are provided inside the fixed frames.

[0009] Also includes:

[0010] The surface of the connecting plate is provided with connecting components;

[0011] The connecting component includes a sleeve that is fixedly connected to the connecting plate;

[0012] The sleeve has a through-connected pull rod inside, and a compression spring is fitted on the surface of the pull rod. The bottom surface of the compression spring is fixedly connected to the sleeve, and a sliding plate is fixedly connected to the top surface of the compression spring. A threaded insert is fixedly connected to the middle of the top surface of the sliding plate.

[0013] Preferably, the threaded insert is connected through the sleeve, and the slide plate is fixedly connected to the pull rod.

[0014] Preferably, a nut is threaded onto the surface of the threaded insert.

[0015] Preferably, the blocking assembly includes an extension plate fixedly connected to the fixing frame, and a cylinder is fixedly connected to the middle of the top surface of the extension plate.

[0016] Preferably, a sliding plate is fixedly connected to the bottom surface of the cylinder, and a sliding rod is connected through one side surface of the sliding plate.

[0017] Preferably, the top surface of the slide bar is fixedly connected to the extension plate, and the bottom of the slide bar is fixedly connected to the conveying device.

[0018] Preferably, a stabilizing plate is fixedly connected to one side of the bottom surface of the extension plate, and a groove is formed on one side surface of the stabilizing plate.

[0019] Preferably, a sliding rod is fixedly installed inside the groove, and the sliding rod is connected through the sliding plate.

[0020] Preferably, a baffle is fixedly connected to one side of the bottom surface of the sliding plate.

[0021] Preferably, a control system receiving sensor is provided on the surface of the conveying device away from the fixed frame.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This intermittent green paper feeding device for book production, by setting up connecting components, makes the disassembly and installation of the negative pressure device more convenient, thereby enabling faster cleaning of dust inside the negative pressure device. Simultaneously, by setting up blocking components, it can block the paper, temporarily preventing subsequent papers from being fed into position until the previous paper completes its corresponding process, thus releasing the subsequent paper. This achieves precise paper spacing control, which is beneficial to improving production efficiency and product quality. The specific details are as follows:

[0023] 1. By setting up a connecting assembly, when dust needs to be cleaned from the negative pressure device, the nut is separated from the threaded rod, and then the pull rod is pulled using a tool. This pull causes the pull rod to move the sliding plate, which separates the threaded rod from the connecting plate mounted on the partition and connecting frame. This allows the negative pressure device to be disassembled for cleaning. During installation, the negative pressure device is placed in the designated position on the connecting frame, allowing the threaded rod on the connecting plate and connecting assembly to penetrate the connecting plate of the partition and connecting frame. The penetration of the threaded rod into the connecting plate is achieved primarily through the action of a compression spring and external pressure applied to the pull rod by the operator. After the threaded rod penetrates the connecting plate, the nut is tightened onto the threaded rod, allowing the negative pressure device to be cleaned. The connecting plates on the partition and connecting frame serve as limiters, allowing the two connecting frames to fit together to complete the installation of the negative pressure device. The connection between the threaded rod and nut makes disassembly simpler; just unscrew the nut and pull out the threaded rod. The threaded rod and nut can usually be replaced or repaired separately. If only the nut or threaded rod is faulty, it doesn't require repairing or remachining the entire bolt hole as is often the case with bolt holes. This makes disassembly and installation of the negative pressure device easier and reduces costs. The negative pressure device is installed in the direction of the conveyor's movement, creating a negative pressure zone on a portion of the conveyor. This allows for paper adsorption, facilitating stable paper transport. The negative pressure device mainly consists of an air inlet, an air pipe, and a negative pressure motor.

[0024] 2. By setting up a blocking component, when blocking the paper inside the fixed frame, the control terminal controls the cylinder, which drives the sliding plate to descend. The descent of the sliding plate causes it to move on the sliding rod and sliding bar. At the same time, the descent of the sliding plate causes the baffle to move, thus blocking the paper. This allows the subsequent paper to be temporarily blocked after one paper is delivered to its position until the previous paper completes its corresponding process, at which point the subsequent paper is released. This achieves precise control of the paper spacing, which is beneficial to improving production efficiency and product quality. Attached Figure Description

[0031] 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.

[0032] Please see Figure 1-5 This utility model provides a technical solution: an intermittent green paper feeding device for book and magazine production, including a conveying device 1, a connecting frame 2 fixedly installed on the bottom surface of the conveying device 1; a plurality of partitions 3 fixedly connected to the surface of the connecting frame 2, a plurality of negative pressure devices 4 provided on the surface of the connecting frame 2, connecting plates 5 symmetrically installed on both sides of the negative pressure devices 4, and a fixing frame 7 fixedly connected to both sides of the top surface of the conveying device 1, with a blocking component 8 provided inside the fixing frame 7; it also includes: a connecting component 6 provided on the surface of the connecting plate 5; wherein, the connecting component 6 includes a sleeve 601 fixedly connected to the connecting plate 5; wherein, a pull rod 602 is connected through the sleeve 601, such as Figure 1-5As shown, by setting the connecting component 6, the disassembly and installation of the negative pressure device 4 can be made more convenient, thereby enabling faster cleaning of the dust inside the negative pressure device 4. At the same time, by setting the blocking component 8, the paper can be blocked, so that after one paper is delivered to the position, the subsequent paper can be temporarily blocked until the previous paper completes the corresponding process, and then the subsequent paper can be released, achieving precise control of the paper spacing, which is beneficial to improving production efficiency and product quality.

[0033] A compression spring 603 is fitted onto the surface of the pull rod 602. The bottom surface of the compression spring 603 is fixedly connected to the sleeve 601. A sliding plate 604 is fixedly connected to the top surface of the compression spring 603. A threaded insert 605 is fixedly connected to the middle of the top surface of the sliding plate 604. The threaded insert 605 is connected through the sleeve 601. The sliding plate 604 is fixedly connected to the pull rod 602. A nut 606 is threaded onto the surface of the threaded insert 605. Figure 3 , 5 As shown, after separating the nut 606 from the threaded rod 605, the pull rod 602 is pulled by a tool. This causes the pull rod 602 to move the slide plate 604. The movement of the slide plate 604 separates the threaded rod 605 from the connecting plate 5 installed on the partition 3 and the connecting frame 2, thereby allowing the negative pressure device 4 to be disassembled. This allows for cleaning of the inside of the negative pressure device 4. At the same time, when installing the negative pressure device 4...

[0034] The blocking assembly 8 includes an extension plate 801 fixedly connected to the fixed frame 7. A cylinder 802 is fixedly connected to the middle of the top surface of the extension plate 801. A sliding plate 803 is fixedly connected to the bottom surface of the cylinder 802. A sliding rod 804 is connected through one side surface of the sliding plate 803. The top surface of the sliding rod 804 is fixedly connected to the extension plate 801, and the bottom of the sliding rod 804 is fixedly connected to the conveying device 1. A stabilizing plate 805 is fixedly connected to one side of the bottom surface of the extension plate 801. A groove 806 is formed on one side surface of the stabilizing plate 805. A sliding rod 807 is fixedly installed inside the groove 806. The sliding rod 807 is connected through the sliding plate 803. A baffle 808 is fixedly connected to one side of the bottom surface of the sliding plate 803. Figure 4As shown, by setting the blocking component 8, when blocking the paper inside the fixed frame 7, the control terminal controls the cylinder 802, so that the cylinder 802 can drive the sliding plate 803 to descend. The descent of the sliding plate 803 causes the sliding plate 803 to move on the sliding rod 804 and the sliding rod 807. At the same time, the descent of the sliding plate 803 can drive the baffle 808 to move, so that the baffle 808 can block the paper. This allows the subsequent paper to be temporarily blocked after one paper is delivered to the position, until the previous paper completes the corresponding process, and then the subsequent paper is released. This achieves precise paper spacing control, which is beneficial to improving production efficiency and product quality.

[0035] A control system receiving sensor 9 is provided on the surface of the conveying device 1 away from the fixed frame 7, such as... Figure 2 As shown, the control system receiving sensor 9 is existing technology and its working principle is the same as existing technology. At the same time, the blocking component 8 and the conveying device 1 are started and stopped by the control system receiving sensor 9, thereby realizing the function of intermittent paper conveying.

[0036] Working principle: Before using this intermittent green paper feeding device for book and magazine production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, by setting the connecting component 6, when it is necessary to clean the dust from the negative pressure device 4, after separating the nut 606 from the threaded rod 605, the pull rod 602 is pulled by the working force. This causes the pull rod 602 to move the sliding plate 604. The movement of the sliding plate 604 separates the threaded rod 605 from the connecting plate 5 installed on the partition 3 and the connecting frame 2, thus allowing the negative pressure device 4 to be disassembled. This enables the internal cleaning of the negative pressure device 4. Simultaneously, during the cleaning of the negative pressure device 4... During installation, after placing the negative pressure device 4 at the designated position on the connecting frame 2, the threaded rod 605 on the connecting plate 5 of the negative pressure device 4 and the connecting assembly 6 passes through the partition 3 and the connecting plate 5 of the connecting frame 2. The threaded rod 605 passes through the connecting plate 5 mainly through the action of the compression spring 603 and the external pressure applied to the pull rod 602 by the worker, allowing the threaded rod 605 to pass smoothly through the partition 3 and the connecting plate 5 of the connecting frame 2. After the threaded rod 605 passes through the partition 3 and the connecting plate 5 of the connecting frame 2, the nut 606 is tightened... The threaded rod 605 serves to limit the movement of the negative pressure device 4, the partition 3, and the connecting plate 5 on the connecting bracket 2, allowing the two connecting brackets 2 to fit together and complete the installation of the negative pressure device 4. The connection between the threaded rod 605 and the nut 606 makes disassembly of the negative pressure device 4 simple: just unscrew the nut 606 and pull out the threaded rod 605. This makes the operation relatively simple and convenient. Furthermore, the threaded rod 605 and the nut 606 can usually be replaced or repaired separately. If only the threaded rod 605... When there is a problem with 05 and 606, it is not necessary to repair or re-machine the entire screw hole as with bolt screw holes. This makes it easier to disassemble and install the negative pressure device 4, and can also reduce the increase in cost to a certain extent. At the same time, the installation arrangement of the negative pressure device 4 is in the direction of movement of the conveying device 1, so that a part of the conveying device 1 forms a negative pressure area, which can adsorb the paper and facilitate the stable conveying of the paper. The negative pressure device 4 is mainly composed of a suction port, a suction pipe and a negative pressure motor.

[0037] Secondly, by setting up the blocking component 8, when blocking the paper inside the fixed frame 7, the control terminal controls the cylinder 802, which drives the sliding plate 803 to descend. The descent of the sliding plate 803 causes it to move on the sliding rod 804 and the sliding bar 807. At the same time, the descent of the sliding plate 803 causes the baffle 808 to move, thereby allowing the baffle 808 to block the paper. This allows the subsequent paper to be temporarily blocked after one piece of paper is delivered to the correct position, until the previous piece of paper completes its corresponding process, and then the subsequent paper is released. This achieves precise paper spacing control, which is beneficial to improving production efficiency and product quality.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
