Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder. Background Technology
[0002] Current paper feeding equipment requires operators to manually adjust two limit guide plates to accommodate different paper sizes and prevent positional deviations during transport. While this method can adapt to paper sizes to a certain extent, the manual adjustment is inconvenient and prevents the automatic adjustment of the limit guide plates for precise paper guidance, thus affecting work efficiency. Therefore, it is extremely urgent to design a one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder that can automatically adjust the position of the limit guide structure according to the paper size. Utility Model Content
[0003] In order to overcome the shortcomings of existing paper feeding equipment, which requires operators to manually adjust two limit guide plates to adapt to the feeding of different sizes of paper and avoid positional deviation of paper during the feeding process, although this method can achieve paper size adaptability within a certain range, the manual adjustment method has the disadvantage of inconvenience. One of the purposes of this utility model is to provide a one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder.
[0004] One of the objectives of this utility model is achieved through the following technical solution: a one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder, comprising a frame: a paper feeding assembly, a paper suction assembly, an adjustment assembly, and a paper output platform are arranged from left to right on one side of the frame; a PLC controller is fixedly mounted on the top of the frame; and a fixed frame is fixedly mounted on the top of the other side of the frame; the adjustment assembly includes a first vertical plate and a second vertical plate respectively fixed on one side of the PLC controller and the fixed frame, a fixed plate fixed on one side of the second vertical plate, and a guide plate fixed between the first vertical plate and the second vertical plate. The system comprises: a guide rail 1, a stepper motor 1 fixed to one side of the vertical plate 2, a rotating shaft 1 fixed to the output end of the stepper motor 1, a driving gear 1 fixed to the outer wall of the rotating shaft 1, a synchronous belt meshing with the outer wall of the driving gear 1, a slider fixed to one side of the synchronous belt, a moving plate fixed to one side of the slider, a support frame fixed to one side of the vertical plate 1, and a driven gear rotatably connected to the support frame. The slider is slidably connected to the guide rail 1, and the driven gear is meshed with the synchronous belt. An infrared distance sensor is provided on one side of the moving plate. The infrared distance sensor can detect the distance between the paper edge and the moving plate and transmit the signal to the PLC controller. The PLC controller then drives the adjustment component to adjust the distance between the moving plate and the paper edge, thereby facilitating the adjustment of the moving plate position according to the size of the paper and achieving lateral positioning and guidance of the paper.
[0005] According to the aforementioned one-button intelligent paper size adjustment mechanism for a front-mounted bottom suction nozzle paper feeder, the paper suction assembly includes a support frame fixed to the inner wall of the frame. Support plates are symmetrically fixed to the upper surface of the support frame, and a paper suction platform is fixed to one side of the support plate. A groove is formed on the upper surface of the support plate, and a paper feeding wheel is rotatably connected to the inner wall of the groove. Paper suction nozzles are arranged in a rectangular array on the upper surface of the paper suction platform, and an air supply pipe is connected below each suction nozzle. This facilitates the suction of paper that has tilted upwards, and uses a small amount of air to prevent the paper from becoming stuck.
[0006] According to the aforementioned one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder, a paper feed roller is rotatably connected to the side of the frame near the support plate. This mechanism enables the feeding of paper.
[0007] According to the aforementioned one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder, the paper feeding assembly includes two guide rails symmetrically fixed to the inner sidewall of the frame. A paper feeding platform is slidably connected to the guide rails. A rack is symmetrically fixed to the inner sidewall of the frame, and a drive gear is meshed with the surface of the rack. A stepper motor is fixed to the lower surface of one side of the paper feeding platform, and a rotating shaft is fixed to the output end of the stepper motor. The rotating shaft passes through the drive gear and is fixedly connected to it. The upper surfaces of the paper feeding platform, the suction table, and the output platform are at the same height, facilitating adjustment of the distance between the paper feeding platform and the suction assembly.
[0008] According to the aforementioned one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder, a bracket 1 and a bracket 2 are symmetrically fixed on the upper surface of the paper feeding platform. A stepper motor 3 is fixed on the side of the paper feeding platform near the bracket 1. A rotating shaft 3 is fixed at the output end of the stepper motor 3. A bevel gear 1 is fixed at one end of the rotating shaft 3. A bevel gear 2 is meshed with the outer wall of one side of the bevel gear 1. A rotating rod is fixed in the middle of the bevel gear 2. The rotating rod is rotatably connected to the bracket 1 and the bracket 2. An abutment sleeve 1 is fixed on the outer wall of one side of the rotating rod, and an abutment sleeve 2 is fitted on the outer wall of the other side of the rotating rod. The abutment sleeve 2 and the bracket 2 are movably connected by bolts. This mechanism can drive paper feeding.
[0009] According to the aforementioned one-button intelligent paper size adjustment mechanism for a front-mounted lower suction nozzle paper feeder, a paper feeding sleeve is fitted onto the outer wall of the rotating rod, and both the outer and inner walls of the paper feeding sleeve are provided with anti-slip friction layers. This ensures smooth paper feeding.
[0010] According to the aforementioned one-button intelligent paper size adjustment mechanism for a front-mounted bottom suction nozzle paper feeder, an anti-slip pad is fixedly provided on the lower surface of the frame. This increases the friction between the equipment and the ground, improving the stability of the equipment.
[0011] The above-mentioned solution has the following beneficial effects:
[0012] 1. By adjusting the mechanism, infrared ranging sensor and PLC controller, compared with the existing technology, this equipment uses infrared ranging sensor to detect the distance between the paper edge and the moving plate. The PLC controller can drive the moving plate to move towards the edge of the paper and abut against the edge of the paper. This makes it easy to adjust the position of the moving plate according to the position of the paper. In this way, the moving plate can play a positioning and guiding role for the paper and avoid paper conveying deviation.
[0013] 2. The paper feeding assembly allows for adjustment of the distance between the paper feeding platform and the paper suction table. The gear and rack combination provides a more convenient and stable adjustment method. Furthermore, the detachable paper feeding sleeve allows for friction with the paper surface, thereby driving the paper transport and effectively improving the stability of the paper feeding.

[0027] The paper feeding assembly 2, paper suction assembly 3, adjustment assembly 4, stepper motor 312, and infrared distance sensor 8 are all connected to the PLC controller 6. The air supply pipe 37 is connected to an external air supply device. The equipment is powered by an external power source. Through the paper feeding assembly 2, paper suction assembly 3, adjustment assembly 4, and infrared distance sensor 8, the automatic paper feeding can be realized. The position of the moving plate 410 can be adjusted according to the size of the paper to guide the paper and prevent it from shifting or curling up, thereby effectively improving the practicality and convenience of the equipment.
[0028] Working principle: First, the distance between the paper feeding platform 202 and the paper suction assembly 3 is adjusted by the paper feeding assembly 2. The stepper motor 205 of the paper feeding assembly 2 is started by the PLC controller 6. The stepper motor 205 drives the two drive gears 204 on both sides to rotate through the rotating shaft 206. Since the rack 203 is fixed, the drive gears 204 move on the rack 203 towards one side of the paper suction assembly 3, thereby driving the paper feeding platform 202 to move towards one side of the paper suction assembly 3. At the same time, the paper feeding platform 202 moves on the guide rail 201. Since the position of the guide rail 201 is fixed and limit grooves are opened on its upper and lower sides, the paper feeding platform 202 will not fall during the movement, thus moving the paper feeding platform 202 to the appropriate position.
[0029] Then, the paper is placed on the paper feeding platform 202, and the stepper motor 12 is started by the PLC controller 6. The stepper motor 12 drives the bevel gear 14 to rotate through the shaft 13. The bevel gear 14 meshes with the bevel gear 25, thereby driving the bevel gear 25 to rotate. The rotation of the bevel gear 25 drives the rotating rod 16 to rotate. Since the inner and outer walls of the paper feeding sleeve 19 are provided with anti-slip friction layers 20, the rotating rod 16 drives the paper feeding sleeve 19 to rotate. The paper feeding sleeve 19 abuts against the upper surface of the paper, thereby driving the paper to be conveyed to the paper suction assembly 3.
[0030] When the paper is fed to the paper suction assembly 3, a small amount of gas is blown out from the four suction nozzles 36 to adsorb the paper and prevent it from curling up. However, this adsorption force is less than the conveying force, so the paper will still move towards the paper output platform 5 under the drive of the paper feeding sleeve 19 and the paper feeding roller 35. When the paper moves to the paper suction assembly 3 and is detected by the infrared distance sensor 8, the infrared distance sensor 8 detects the distance between the edge of the paper and the moving plate 410 and transmits the detection signal to the PLC controller 6. The PLC controller 6 drives the stepper motor 405 to start, and the stepper motor 405 drives the drive gear 407 to rotate through the rotating shaft 406. The rotation of the drive gear 407 drives the synchronous belt 408 to rotate, which in turn drives the driven gear 412 to rotate. When the synchronous belt 408 rotates, it drives the slider 409 to move on the guide rail 404. Since the slider 409 is connected to the moving plate 410, it drives the moving plate 410 to move towards one side of the paper. The moving plate 410 abuts against the edge of the paper, thereby limiting and guiding paper of different sizes within a certain range, thus preventing the paper from shifting position during transport. It is easy to use, effectively improving the practicality and convenience of the device, effectively reducing the labor intensity of the workers, and improving the transport efficiency.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
