Description

Technical Field

[0001] This utility model relates to the field of paper pulling device technology, and in particular to an automatic paper pulling device. Background Technology

[0002] An automatic paper pulling device is a device that uses electricity to stretch fiberboard. It uses the power provided by the motor to unwind, straighten, and unfold the fiberboard, and then press and shape it. It can help workers improve packaging efficiency and has a wide range of applications in modern industry, logistics and transportation.

[0003] However, most of the existing automatic paper pulling devices on the market are not convenient for leveling fiberboard, resulting in uneven fiberboard surfaces that affect the quality of subsequent packaging. Furthermore, most of the existing automatic paper pulling devices on the market are not convenient for workers to adjust the cutting width of the pulled fiberboard according to packaging needs, resulting in low flexibility.

[0004] Therefore, those skilled in the art have provided an automatic paper-pulling device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic paper pulling device. The fiberboard is sandwiched in the middle by two leveling belts in the leveling mechanism and pressed by a roller plate, so that the fiberboard is pressed flat during the movement. The bidirectional threaded rod in the cutting mechanism is threadedly connected to the moving block, and the circular cutter driven by the second servo motor facilitates the adjustment of the cutting width of the pulled fiberboard.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic paper pulling device includes a base frame, a mounting frame, and a cutting table. The rear end of the upper end of the base frame is fixedly connected to the mounting frame, and the outer wall of the front end of the base frame is fixedly connected to the cutting table. A leveling mechanism is provided inside the base frame. The leveling mechanism includes a roller plate and multiple pressure rollers. A first servo motor is provided in the cavity at the front end of one side of the base frame. A leveling belt is fitted on each of the pressure rollers. The cutting table is equipped with a cutting mechanism, which includes a bidirectional threaded rod and two moving blocks. The front end of the cutting table has a paper outlet. Both sides of the outer wall of the bidirectional threaded rod are threaded to the moving blocks. A second servo motor is installed in the cavity inside the moving block. The output shaft of the second servo motor passes through the moving block and is fixedly connected to a circular cutter. The above technical solution uses a leveling belt fitted on the pressure roller to clamp the fiberboard in the middle, and applies pressure through a high-density, heavy roller plate to flatten the fiberboard during movement. In addition, the spacing between the moving blocks can be changed by connecting the bidirectional threaded rod to the moving block. The second servo motor inside the moving block drives the circular cutter, which facilitates the adjustment of the cutting width of the fiberboard.

[0007] Furthermore, paper rollers are rotatably connected to the front and rear ends of the inner walls on both sides of the mounting frame, and a transition roller is rotatably connected to the front end of the mounting frame. The above technical solution allows the paper roll to be fitted onto the paper roller, enabling the paper roll to be installed onto the mounting frame along with the paper roller. The two paper rollers are fitted with an outer paper roll and an inner paper roll, respectively. The transition roller, which is rotatably connected to the front end of the mounting frame, can prevent the fiberboard from rubbing against the bottom surface of the mounting frame, thereby reducing wear on the fiberboard during movement.

[0008] Furthermore, two sliding grooves are provided at the front ends of the outer walls on both sides of the bottom frame, and sliders are fixedly connected to the front and rear ends of the outer walls on both sides of the roller plate, and the sliders are slidably connected to the sliding grooves. The above technical solution prevents the roller plate from detaching from the bottom frame by sliding the groove on the bottom frame to the slider on the roller plate. At the same time, the roller plate is allowed to float up and down within the bottom frame under the action of the groove to adapt to different fiberboard thicknesses.

[0009] Furthermore, the front ends of the inner walls on both sides of the bottom frame and the inner walls on both sides of the roller plate are rotatably connected to the pressure roller, and the output shaft of the first servo motor passes through the bottom frame and is fixedly connected to the pressure roller. Through the above technical solution, multiple pressure rollers are rotatably connected to both the bottom frame and the roller plate, enabling the leveling belt fitted on the pressure rollers to move. Meanwhile, the output shaft of the first servo motor is fixedly connected to a pressure roller, allowing the leveling belt below to move actively.

[0010] Furthermore, the leveling belts are bonded together, and a control panel is provided in the middle of the upper part of the cutting table; Through the above technical solution, under the weight pressure of the roller press, the upper leveling belt tends to fit with the lower leveling belt, thereby clamping the fiberboard in the middle and flattening it. The control panel set on the cutting table allows the staff to control the operation of the device.

[0011] Furthermore, both sides of the bidirectional threaded rod pass through the cutting table and are fixedly connected with handwheels, and the moving blocks are slidably connected to the top surface inside the paper outlet; The above technical solution allows workers to easily rotate the bidirectional threaded rod on the cutting table by using a handwheel fixedly connected to it. The threaded connection between the bidirectional threaded rod and the moving block allows workers to change the position of the moving block inside the paper outlet.

[0012] Furthermore, electric telescopic rods are fixedly connected to both sides of the inner top surface of the cutting table, and straight cutting blades are fixedly connected to the lower ends of the electric telescopic rods. The above technical solution allows two electric telescopic rods fixedly connected to the cutting table to drive the straight cutter to move up and down in front of the paper outlet, and the straight cutter can cut the pulled-out fiberboard.

[0013] This utility model has the following beneficial effects: 1. The present invention proposes an automatic paper pulling device, which uses a leveling belt fitted on the pressure roller in the leveling mechanism to clamp the fiberboard in the middle, and applies pressure through a high-density and heavy roller plate to press the fiberboard flat during the movement, thereby avoiding unevenness on the surface of the pulled fiberboard and improving the quality of subsequent packaging.

[0014] 2. The automatic paper pulling device proposed in this utility model uses a bidirectional threaded rod in the cutting mechanism to be threadedly connected to the moving block. This allows the bidirectional threaded rod to change the spacing between the moving blocks. In conjunction with the second servo motor in the moving block, a circular cutter is driven to cut the side of the pulled-out fiberboard. This makes it easy for the staff to adjust the cutting width of the pulled-out fiberboard according to the packaging needs, and it has high flexibility. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1-5 This utility model provides a specific implementation method: An automatic paper pulling device includes a base frame 1, a mounting frame 2, and a cutting table 5. The rear end of the upper end of the base frame 1 is fixedly connected to the mounting frame 2, and the outer wall of the front end of the base frame 1 is fixedly connected to the cutting table 5. A leveling mechanism 6 is provided inside the base frame 1. The leveling mechanism 6 includes a roller plate 602 and multiple pressure rollers 605. A first servo motor 601 is provided in the cavity at the front end of one side of the base frame 1. A leveling belt 606 is fitted on each of the pressure rollers 605. The cutting table 5 is equipped with a cutting mechanism 8, which includes a bidirectional threaded rod 802 and two moving blocks 804. The front end of the cutting table 5 is provided with a paper outlet 801. Both sides of the outer wall of the bidirectional threaded rod 802 are threadedly connected to the moving blocks 804. A second servo motor 805 is provided in the cavity inside the moving block 804. The output shaft of the second servo motor 805 passes through the moving block 804 and is fixedly connected to a circular cutter 806.

[0019] The fiberboard is sandwiched in the middle by the leveling belt 606 fitted on the pressure roller 605 in the leveling mechanism 6, and is pressed flat by the high-density and heavy roller plate 602. This flattens the fiberboard during movement, thus avoiding unevenness on the surface of the pulled fiberboard and improving the quality of subsequent packaging. In addition, the bidirectional threaded rod 802 in the cutting mechanism 8 is threadedly connected to the moving block 804, so the spacing between the moving blocks 804 can be changed by the bidirectional threaded rod 802. The second servo motor 805 in the moving block 804 drives the circular cutter 806 to cut the side of the pulled fiberboard, which makes it easy for the staff to adjust the cutting width of the pulled fiberboard according to the packaging needs, thus providing high flexibility.

[0020] Paper rollers 3 are rotatably connected to the front and rear ends of the inner walls on both sides of the mounting frame 2. A transition roller 4 is rotatably connected to the front end of the mounting frame 2. By fitting the paper roll onto the paper roller 3, the paper roll can be installed onto the mounting frame 2 along with the paper roller 3. The two paper rollers 3 respectively fit the outer lining paper roll and the inner lining paper roll. The transition roller 4 rotatably connected to the front end of the mounting frame 2 can avoid friction between the fiberboard and the bottom surface of the mounting frame 2, reducing wear during fiberboard movement. Two sliding grooves 604 are opened at the front ends of the outer walls on both sides of the frame 1. The front and rear ends of the outer walls on both sides of the roller plate 602 are fixedly connected. There are sliders 603, all of which are slidably connected to slide grooves 604. By sliding the slide grooves 604 on the bottom frame 1 and the sliders 603 on the roller plate 602, the roller plate 602 is prevented from detaching from the bottom frame 1. At the same time, under the action of the slide grooves 604, the roller plate 602 is allowed to float up and down within the bottom frame 1 to adapt to different fiberboard thicknesses. The front ends of the inner walls on both sides of the frame 1 and the inner walls on both sides of the roller plate 602 are rotatably connected to the pressure rollers 605. The output shaft of the first servo motor 601 passes through the bottom frame 1 and is fixedly connected to the pressure rollers 605. Multiple pressure rollers 605 are rotatably connected to the roller press plate 602, allowing the leveling belts 606 fitted on the pressure rollers 605 to move. The output shaft of the first servo motor 601 is fixedly connected to one of the pressure rollers 605, enabling the lower leveling belts 606 to move actively. The leveling belts 606 are pressed together. A control panel 7 is located in the middle of the upper end of the cutting table 5. Under the pressure of the roller press plate 602, the upper leveling belts 606 tend to press together with the lower leveling belts 606, thus clamping the fiberboard in the middle and flattening it. The control panel 7 on the cutting table 5 allows the operator to easily control the operation of the device. Handwheels 803 are fixedly connected to both sides of the threaded rod 802 through the cutting table 5. The moving blocks 804 are slidably connected to the top surface inside the paper outlet 801. The handwheels 803 fixedly connected to the threaded rod 802 allow the operator to easily rotate the threaded rod 802 on the cutting table 5. The threaded connection between the threaded rod 802 and the moving blocks 804 allows the operator to change the position of the moving blocks 804 inside the paper outlet 801.

[0021] Electric telescopic rods 807 are fixedly connected to both sides of the top surface inside the cutting table 5. A straight cutter 808 is fixedly connected to the lower end of each electric telescopic rod 807. The two electric telescopic rods 807 fixedly connected to the cutting table 5 can drive the straight cutter 808 to move up and down in front of the paper outlet 801. The straight cutter 808 can be used to cut the pulled-out fiberboard.

[0022] Working principle: When using this automatic paper pulling device, the operator first places the outer and inner paper rolls onto the paper roller 3. Then, the fiberboard is passed through the leveling belt 606 and extends out of the paper outlet 801, clamping the fiberboard between the two leveling belts 606. The operator uses the handwheel 803 to drive the bidirectional threaded rod 802 to rotate, changing the distance between the two moving blocks 804 to the desired size. Next, the operator uses the control panel 7 to start the first servo motor 601 to drive the pressure roller 605 to rotate, making the leveling belt 606 move. At the same time, the high-density, heavy roller plate 602 applies pressure, pressing the fiberboard flat during the movement to prevent unevenness on the surface of the pulled-out fiberboard. Finally, the operator uses the control panel 7 to start the second servo motor 805 inside the moving block 804 to drive the circular cutter 806 to cut the side of the pulled-out fiberboard. Then, the control panel 7 controls the electric telescopic rod 807 to push the straight cutter 808 to cut the fiberboard.
