Description
Technical Field
[0001] This application relates to the field of transportation, and more particularly to a paper transfer device for a printing press with a correction mechanism. Background Technology
[0002] Currently, in the printing production process, the stability and accuracy of paper transfer directly affect printing quality and production efficiency.
[0003] In traditional printing press paper transfer devices, paper is prone to problems such as shifting and wrinkling during operation. Some correction devices use a single sensor for feedback control, which has a slow response speed and cannot adapt to rapid adjustments of different paper sizes.
[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from drawbacks such as complex structure and limited corrective effect. Utility Model Content
[0005] To solve the above-mentioned technical problems, this application provides a printing press paper transfer device with a correction device.
[0006] This application provides a printing press paper transfer device with a web correction mechanism, which adopts the following technical solution:
[0007] A printing press paper transfer device with a correction mechanism includes a frame, a transport mechanism, a first correction mechanism, a return mechanism, and a flattening mechanism. The transport mechanism is mounted on the frame and is fixedly connected to the frame. The first correction mechanism is mounted on the frame and is fixedly connected to the frame. The return mechanism is mounted on the frame and is fixedly connected to the frame. The flattening mechanism is mounted on the frame and is slidably connected to the frame.
[0008] By adopting the above technical solution: the transport mechanism is fixedly installed on the frame, and the transport mechanism can smoothly transport the paper to the corresponding position. The first correction mechanism is fixedly installed on the frame on one side of the conveying device. When the paper deviates, the correction mechanism can straighten the paper. The return mechanism is installed at the final working position of the correction mechanism. When the correction mechanism is running at this time, the return mechanism will help the correction mechanism to return. When the paper is transported and becomes uneven, the flattening mechanism will flatten it.
[0009] Preferably, the transport mechanism includes a conveyor belt, a drive rod, a driven rod, and a first motor. The drive rod is mounted on the first motor and is fixedly connected to the first motor. The first motor is fixedly mounted on the frame, and the conveyor belt is mounted on the drive rod and the driven rod, which are placed in parallel.
[0010] By adopting the above technical solution: the active rod is fixedly connected to the first motor and fixed on the frame. The active rod is driven to rotate by the first motor. A conveyor belt is provided on the active rod, and a driven rod is provided at the other end of the conveyor belt. The active rod and the driven rod are placed parallel to each other, which ensures that the paper can be transported stably. The transport mechanism plays a major role in the paper transport.
[0011] Preferably, the first correction mechanism includes a first crank, a first connecting rod, and a first guide plate. One end of the first crank is hinged to the frame on one side of the transport mechanism, and the other end of the first crank is hinged to one end of the first connecting rod. The end of the first connecting rod away from the first crank is hinged to the first guide plate, and the bottom of the first guide plate is attached to the frame.
[0012] Preferably, a second correction mechanism with the same structure is provided on the frame on the other side of the transport mechanism, including a second crank, a second connecting rod and a second guide plate. The position of the second guide plate of the second correction mechanism corresponds to the first guide plate of the first correction mechanism, and the hinge joint between the first crank and the first connecting rod of the first correction mechanism and the hinge joint between the second crank and the second connecting rod of the second correction mechanism are fixedly connected by a round rod.
[0013] By adopting the above technical solution: the first crank, the first connecting rod and the first guide plate form a sliding guide plate structure. When the first crank is rotated, the connected first connecting rod swings, and the first guide plate connected to the first connecting rod slides on the frame. Similarly, a second correction mechanism with the same structure is also provided on the frame on the other side of the conveyor belt, and the two are connected by a round rod. When the paper deflects, the first guide plate of the first correction mechanism and the second guide plate of the second correction mechanism slide simultaneously to correct the deflected paper.
[0014] Preferably, the return mechanism includes a spring and a limiting plate, and the return mechanism is located at the working limit positions of the first correction mechanism and the second correction mechanism respectively. One end of the spring is fixedly installed on the frame, and the other end of the spring is installed with a limiting plate, which is fixedly connected to the spring.
[0015] By adopting the above technical solution: one end of the spring is fixedly connected to the limiting plate, and the other end is fixedly installed on the frame. When the correction mechanism is running at this time, the correction mechanism will push the limiting plate and compress the spring, thereby reminding the correction mechanism to perform a return movement. When the correction mechanism returns, the spring will give it a return force through the limiting plate, which helps the correction mechanism to return more effortlessly.
[0016] Preferably, the flattening mechanism includes a roller, a second motor, and a first support rod. The roller is fixedly connected to the second motor, and the second motor is fixedly mounted on one end of the first support rod. The other end of the first support rod is set as a first slider, and the first slider is slidably connected to the frame.
[0017] Preferably, a second support rod is provided at the end of the roller that is not connected to the second motor. One end of the second support rod is sleeved on the roller, and the other end is set as a second slider. The second slider is slidably connected to the frame, and the position of the first support rod corresponds to the position of the second support rod.
[0018] Preferably, threaded rods are provided below the first slider of the first support rod and the second slider of the second support rod, and threaded holes are provided at the frame that mate with the threaded rods.
[0019] By adopting the above technical solution: the roller is fixedly connected to the second motor, and the second motor is fixed on the first support rod. When the other end of the first support rod is set as a slider, the position of the roller can be adjusted at will. When the paper is running at this time, the second motor drives the roller to rotate, and the rotation direction is opposite to that of the active rod. The paper passes through the relative movement gap between the roller and the conveyor belt, thereby flattening the uneven area. A second support rod is provided on the other side of the roller to keep the roller stable and ensure that the gap between the roller and the conveyor belt is uniform. Tightening the threaded rod can adjust the size of the gap between the roller and the conveyor belt more finely.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. The transport mechanism is fixedly installed on the frame. The transport mechanism can smoothly transport the paper to the corresponding position. The first correction mechanism is fixedly installed on the frame on one side of the conveyor. When the paper deviates, the correction mechanism can straighten the paper. The return mechanism is installed at the final working position of the correction mechanism. When the correction mechanism is running at this time, the return mechanism will help the correction mechanism to return. When the paper is transported and becomes uneven, the flattening mechanism will flatten it.
[0022] 2. The first crank, the first connecting rod, and the first guide plate form a sliding guide plate structure. When the first crank is rotated, the connected first connecting rod swings, and the first guide plate connected to the first connecting rod slides on the frame. Similarly, a second correction mechanism with the same structure is also provided on the frame on the other side of the conveyor belt, and the two are connected by a round rod. When the paper deflects, the first guide plate of the first correction mechanism and the second guide plate of the second correction mechanism slide simultaneously to correct the deflected paper.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0028] This application discloses a paper transfer device for a printing press with a web-correcting mechanism. (Refer to...) Figure 1-3 The system includes a frame 1, a transport mechanism 2, a first correction mechanism 3, a second correction mechanism 4, a return mechanism 6, and a flattening mechanism 7. The transport mechanism 2 includes a conveyor belt 21, a drive rod 22, a driven rod 23, and a first motor 24. The drive rod 22 is fixedly connected to the first motor 24, which is fixed to the frame. The drive rod 22 and the first motor 24 are located on the side away from the first correction mechanism 3 and the second correction mechanism 4 to prevent the first motor 24 from obstructing the movement of the two correction mechanisms. A transmission belt 21 is laid on the drive rod 22, and the driven rod 23 is located at the other end of the conveyor belt 21. L-shaped frames 1 are provided on both sides of the conveyor belt 21. The vertical surfaces of the frames 1 are close to the sides of the conveyor belt 21, and the frames 1 are not higher than the upper surface of the conveyor belt 21. The first correction mechanism 3 and the second correction mechanism 4 have the following structures. At the same location but different, the first crank 31 is hinged to the frame 1, and the first crank 31 has an outwardly extending handle at the hinge point to facilitate the rotation of the first crank 31. The first crank 31 is hinged to the first connecting rod 32, and the other end of the first connecting rod 32 is hinged to the first guide plate 33. The first guide plate 33 reciprocates along the frame 1 under the indirect drive of rotating the first crank 31. The second correction mechanism 4 is located on the frame 1 on the other side, and its movement state is the same as that of the first correction mechanism 3. The hinge point between the first crank 31 and the first connecting rod 32 of the first correction mechanism 3 and the hinge point between the second crank 41 and the second connecting rod 42 of the second correction mechanism 4 are fixedly connected by a round rod 5. The round rod 5 can help the first correction mechanism 3 and the second correction mechanism 4 to operate simultaneously, so that the paper can be better corrected.
[0029] The return mechanism 6 includes a spring 61 and a limiting plate 62. The return mechanism 6 is located at the working limit positions of the first correction mechanism 3 and the second correction mechanism 4. A section of the frame 1 extends from the position where the spring 61 is installed. One end of the spring 61 is fixedly installed on the frame 1, and the other end is fixedly connected to the limiting plate 62. When the first correction mechanism 3 and the second correction mechanism 4 are in their return stroke, the spring 61 provides a return force through the limiting plate 62 to assist in the return. The flattening mechanism 7 is located slightly inside the first motor 24. The flattening mechanism 7 includes a roller 71, a second motor 72, and a first support rod 73. The upper side of the first support rod 71 is fixedly connected to the second motor 72, and the second motor 72 is fixedly connected to the roller 71. The lower side is provided as a first slider 731, which is connected to the frame 1. There is a groove at the sliding connection, where the first slider 731 slides to change the gap between the roller 71 and the conveyor belt 21. The second support rod 74 is added to help the roller 71 rotate smoothly and provide it with support. The upper and lower structure of the second support rod 74 is the same as that of the first support rod 73. One end of the second support rod 74 is fitted onto the roller 72, and the other end is set as the second slider 741. The second slider 741 is slidably connected to the frame 1, and the position of the first support rod 73 corresponds to the position of the second support rod 74. Both the first support rod 73 and the second support rod 74 are provided with screw rods 8 on their lower sides. The corresponding screw rods 8 are provided with screw holes 11 on the frame 1 to cooperate with them. The screw rods 8 can be turned to support the first support rod 73 and the second support rod 74 to move up and down, so that the gap can be changed more precisely and stably.
[0030] The working principle of the paper transfer device for a printing press with a correction device in this application is as follows: When the paper is placed on the conveyor belt 21, it may not be in the correct position. When the first motor 24 drives the drive rod 22 to rotate and the conveyor belt 21 transports the paper, the first crank 31 is rotated, so that the first correction mechanism 3 and the second correction mechanism 4 operate simultaneously. During the rotation of the first crank 31, the first guide plate 33 and the second guide plate 43 are driven to slide on the frame. The size of the paper is the same as the width of the conveyor belt 21. This pushes the paper that has protruded due to the deviation back to the correct position. After the adjustment is completed, the first guide plate 33 and the second guide plate 43 reach the working limit position and quickly return to the position under the action of the return mechanism 6 for readjustment. The paper may wrinkle during the adjustment process. When it runs to the flattening mechanism 7, the position of the adjusting screw rod 8 is adjusted to adjust the height of the roller 71. The roller 71 is flattened under the rotation and transport of the conveyor belt 21, thereby transferring the paper.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the structure, shape, or principle of this application. All such changes should be covered within the protection scope of this application.
