Description

Technical Field

[0001] This utility model relates to the field of printing and transmission technology, specifically to an instruction manual anti-paper jam printing and transmission device. Background Technology

[0002] In the modern printing industry, printing transport devices are key equipment connecting various printing processes. Their performance directly affects production efficiency and printing quality. Traditional printing transport devices have revealed many problems that urgently need to be solved during actual operation.

[0003] Paper jams are one of the most prominent problems. During the paperboard transport process, due to the lack of an effective guidance and adjustment mechanism for the transport path, paperboards of different sizes and thicknesses are prone to positional deviation, tilting, or even mutual compression when passing through the conveyor belt, which leads to paper jam failures. Once a paper jam occurs, not only does it require manual shutdown for cleaning, which consumes a lot of time and labor costs, but it may also damage the products being printed, reducing production efficiency and product qualification rate.

[0004] Traditional equipment is not well adapted to different sizes of cardboard. When printing different specifications of cardboard, it is often difficult to quickly and accurately adjust the parameters and structure of the transmission device to meet the transmission requirements of different cardboard. This makes printing companies inefficient in dealing with diverse order demands, and they frequently have to change equipment or carry out complex debugging work, which further increases production costs.

[0005] In view of the above-mentioned problems with traditional printing transmission, the development of a paper jam prevention printing transmission device for instruction manuals is of great practical significance, providing the printing industry with an efficient, stable and reliable transmission solution. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an instruction manual anti-paper jam printing and transmission device, which solves the aforementioned problems.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a printing transmission device for preventing instruction manual paper jams, comprising a machine body, a conveyor belt disposed at the upper end of the machine body, two fixing blocks respectively installed opposite each other on both sides of the inner wall of the front end of the machine body, micro motors respectively installed on both sides of the outer surface of the front end of the machine body, drive gear disks connected to the output ends of the micro motors respectively, a frame connected to the rear end surface of the upper end of the machine body, a rotary motor first installed at the center of the upper surface of the frame, limit plates respectively disposed on both sides of the lower surface of the frame, and further comprising:

[0010] Preferably, a second rotary motor is installed at the lower end of the machine body, a first drive gear is connected to the output end of the second rotary motor, a first chain is movably sleeved on the outer end of the first drive gear, and the other end of the first chain is correspondingly sleeved on the outer end of the first driven gear.

[0011] Preferably, a screw is provided at the center of the inner opposite surface of the two fixed blocks. A driven gear plate is installed at one end of the screw through the interior of one fixed block and extending to the outer end of the fixed block. A chain is movably sleeved at the outer end of the driven gear plate. The other end of the chain is respectively sleeved at the outer end of the two drive gear plates. An installation groove is provided on the front surface of the two fixed blocks.

[0012] Preferably, mounting blocks are slidably fitted inside the mounting groove, and belts are connected to the front surface of each mounting block, with the two belts arranged in a relatively parallel manner.

[0013] Preferably, the guiding assembly includes a slider, a support rod, and a roller. The outer ends of the two screws are respectively threaded with sliders, and the front end surfaces of the two sliders are respectively hinged to support rods.

An internal rack is connected to one side of the opposite surface of the two slide plates, and the inner side of the two internal racks is engaged with the outer end of the drive gear plate.

[0015] Compared with the prior art, this utility model provides a paper jam prevention and transmission device for instruction manual printing, which has the following beneficial effects:

[0016] During the transport process, when encountering cardboard of different sizes, a micro motor can be activated. Through the linkage of chain two, driven toothed disc two, and screw, the slider drives the roller to move, thereby adjusting the belt tension and relative position. This ensures that cardboard of various sizes can be smoothly transported on the conveyor belt, reducing the occurrence of paper jams. This not only improves the efficiency of printing production and avoids frequent downtime due to paper jams, but also ensures the continuity of the printing process, reduces the cost of manual intervention, and improves overall production efficiency.

[0017] When the position of the limiting plate needs to be adjusted, start the rotary motor one, drive the toothed disc three to mesh with the internal rack, and drive the slide plate to slide in the slide groove, thereby realizing the position adjustment of the limiting plate. This ensures that the cardboard can always be kept in the correct position during the transmission process, effectively avoiding the problem of cardboard offset or tilting, reducing the scrap rate, improving printing quality, and meeting the production needs of high printing precision.

[0049] Drive gear 18: Connected to the output of micro motor 3. After micro motor 3 is started, drive gear 18 rotates, which drives driven gear 16 to rotate via chain 17, thereby driving screw 14 to rotate and adjusting guide components.

[0050] Support rod 19: One end is hinged to the front surface of slider 15, and the other end is equipped with roller 20. When slider 15 moves under the drive of screw 14, support rod 19 drives roller 20 to move, thereby adjusting belt 21.

[0051] Roller 20: Installed at the front end of support rod 19, its outer end surface rolls against the inner surface of belt 21. By moving it, the tension and relative position of belt 21 are changed, thus guiding the paperboard and preventing paper jams.

[0052] Belt 21: Installed on the front surface of the mounting block 22, with two belts 21 arranged parallel to each other. In conjunction with the roller 20, they guide the cardboard during transport, preventing it from jamming.

[0053] Mounting block 22: It slides into the mounting groove on the front surface of the fixing block 4, and its front end is connected to the belt 21. The mounting block 22 can slide flexibly in the mounting groove, so that the belt 21 can be flexibly adjusted in position as needed.

[0054] Slide plate 23: Installed inside both ends of the frame 5, with its lower surface extending to the outer end of the lower end of the frame 5 via a groove and connecting to the limiting plate 7. Under the meshing action of the drive gear 25 and the internal rack 24, the slide plate 23 slides in the groove, causing the limiting plate 7 to adjust its position.

[0055] Internal rack 24: Connected to one side of the opposing surfaces of the two slide plates 23, and meshes with the drive gear 25. When the rotary motor 6 drives the drive gear 25 to rotate, the meshing of the internal rack 24 with the drive gear 25 causes the slide plates 23 to move.

[0056] Drive gear 25: Installed at the output end of rotary motor 6, extending to the center of the frame 5, and meshes with internal rack 24. After rotary motor 6 is started, drive gear 25 rotates, and through meshing with internal rack 24, drives slide plate 23 to slide, thereby adjusting the position of limit plate 7.

[0057] Instructions for use

[0058] During operation, the rotary motor 8 is started first. The output of the rotary motor 8 drives the drive gear 9 to rotate. The drive gear 9 transmits power to the driven gear 13 through the movable chain 10. The driven gear 13 is fixedly connected to one end of one of the guide rollers 11, so the guide roller 11 will rotate accordingly. Since the guide roller 11 is tightly fitted to both ends of the inside of the conveyor belt 2, the rotation of the guide roller 11 will drive the conveyor belt 2 to run. Several auxiliary rods 12 arranged inside the conveyor belt 2 play a role in supporting and assisting the smooth operation of the conveyor belt 2, ensuring that the cardboard can be smoothly conveyed forward on the conveyor belt 2. When adjustment is needed... The guide assembly is designed to accommodate cardboard of different sizes to prevent jamming during transport. When this occurs, the micro motor 3 is activated, and its output drives the drive gear 18 to rotate. The drive gear 18 transmits power to the driven gear 16 via a movable chain 17. The driven gear 16 is mounted on one end of the screw 14, causing the screw 14 to rotate along with it. Since the outer end of the screw 14 is threaded with a slider 15, the rotation of the screw 14 causes the slider 15 to move linearly along the screw 14. A support rod 19 is hinged to the front surface of the slider 15. The roller 20 is installed, and the movement of the slider 15 drives the roller 20 to move via the support rod 19. The outer end surface of the roller 20 rolls against the inner surface of the belt 21. By adjusting the position of the roller 20, the tension and relative position of the belt 21 can be adjusted to accommodate different sizes of cardboard and prevent the cardboard from jamming during transport. The mounting block 22 slides in the mounting groove, allowing the belt 21 to be flexibly adjusted in position. The two belts 21 are set relatively parallel to each other, which can better guide and transport the cardboard. If it is necessary to adjust the position of the limiting plate 7, it can better limit and guide the transported cardboard. When the drive plate is turned on, the rotary motor 6 is started. The output end of the rotary motor 6 extends to the center of the inside of the frame 5, driving the drive gear plate 25 to rotate. The slide plate 23 installed at both ends inside the frame 5 has its lower surface extending to the lower outer end of the frame 5 through a slide groove and connected to the upper surface of the limiting plate 7. An internal rack 24 is connected to one side of the opposite surface of the slide plate 23, and the internal rack 24 is meshed with the outer end of the drive gear plate 25. The rotation of the drive gear plate 25 will drive the slide plate 23 to slide in the slide groove through the meshing with the internal rack 24, thereby enabling the limiting plate 7 to adjust its position and meet the limiting requirements when transferring different sizes of cardboard.
