Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for paper product processing and production, in particular to a feeding mechanism of a servo-controlled high-speed paper container forming machine. Background Art

[0002] Paper containers usually refer to containers made of paper as raw material for holding objects, such as disposable cups, paper bowls, etc. When paper containers are processed and formed, the corresponding paper needs to be conveyed into the forming machine through a feeding mechanism to facilitate the production of paper containers.

[0003] The existing Chinese patent with application number: 202220157910.0 discloses a bottom paper feeding mechanism for a paper container forming machine, including a frame, a panel, a limit assembly, an adjustment assembly, a flattening piece and a conveying roller, the limit assembly including a fixed end and a movable end, the fixed end is fixedly arranged on the panel, the movable end is slidably connected to the panel, a limit gap with adjustable width is formed between the fixed end and the movable end, the bottom paper is embedded in the limit gap, the adjustment assembly is fixedly arranged on the panel, the adjustment end of the adjustment assembly is fixedly connected to the movable end, so as to drive the movable end to slide, the flattening piece is suspended on the panel, a gap is formed between the flattening piece and the panel, the height dimension of the gap is adapted to the thickness dimension of the bottom paper, and the conveying roller is rotatably connected to the frame.

[0004] Although the above technology has the effect of flattening the base paper to a certain extent during the feeding process, in actual use, the pressure plate used to flatten the paper cannot be moved up and down flexibly in time, that is, it cannot easily adapt to papers of different thicknesses. Therefore, when changing production batches, personnel need to spend extra time to disassemble and assemble it to adapt to the thickness of the new paper. Therefore, in order to solve the above technical problems, we propose a feeding mechanism for a servo-controlled high-speed paper container forming machine. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a feeding mechanism for a servo-controlled high-speed paper container forming machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A feeding mechanism of a servo-controlled high-speed paper container forming machine comprises a frame, a paper roll is installed at the feed end of the frame, a motor for driving the paper roll to rotate is installed at the rear side of the feed end of the frame, the paper wound on the paper roll moves toward the discharge end of the frame until it is finally moved into the paper container forming machine outside, the discharge end of the frame is provided with a matching clamping and limiting assembly corresponding to the paper, an electric cylinder is provided above the middle of the frame, a linkage plate is installed at the output end of the electric cylinder, a plurality of springs are provided on the lower surface of the linkage plate and a pressure plate is connected to the lower end of the springs, and the lower surface of the pressure plate abuts against the surface of the paper located on the upper surface of the middle of the frame.

[0008] Preferably, the clamping and limiting assembly includes a left-handed and right-handed threaded rod, a guide rod and a limiting plate, the upper ends of the limiting plates are respectively located on both sides of the paper, the left-handed and right-handed threaded rod and the guide rod are respectively installed on the lower end of the limiting plate by means of threads and sliding insertion, and both ends of the left-handed and right-handed threaded rod and the guide rod are installed at the end of the discharging end of the frame.

[0009] Preferably, hand wheels are installed at both ends of the left-handed and right-handed threaded rods, and rollers are provided at the upper end of the limiting plate and contact the two sides of the paper through the rollers.

[0010] Preferably, a plurality of rollers are provided inside the frame body near the feed end, and the paper is wound around the surfaces of the plurality of rollers.

[0011] Preferably, rollers are installed on both sides of the frame body of the frame located between the plurality of rollers and the discharge end.

[0012] Preferably, the four corners of the lower surface of the pressure plate are fixed with limit rods, and matching guide cylinders are provided on the front and rear sides of the frame corresponding to the limit rods.

[0013] Preferably, a mounting tube is connected to the upper side of the frame, the electric cylinder is mounted on the upper end of the mounting tube, and the linkage plate is slidably mounted on the lower end of the interior of the mounting tube.

[0014] The utility model proposes a servo-controlled high-speed paper container forming machine feeding mechanism, which has the following beneficial effects:

[0015] 1: In the utility model, the output end of the electric cylinder pushes the linkage plate to move downward until the pressure plate is finally tightly pressed on the upper surface of the paper below. At this time, the paper is flattened under the pressure of the electric cylinder, thereby avoiding the phenomenon that the paper is wrinkled and bent when it enters the paper container forming machine later, which leads to the production error of the paper container; and because a spring is provided between the linkage plate and the pressure plate, the personnel can control the pressure of the pressure plate on the paper by controlling the extension distance of the output end of the electric cylinder, thereby adapting to papers of different thicknesses and different pressure requirements; at the same time, through the setting of the clamping limit assembly, the personnel can control the distance between the two rollers by rotating the threaded rod left and right, thereby facilitating the limiting and clamping of the front and rear edges of the paper by the two rollers, thereby avoiding the phenomenon of paper deviation, and because there is rolling friction between the roller and the paper, the phenomenon of the edge of the paper being scratched and fluffed is effectively avoided.

[0016] 2: The setting of the roller in the utility model effectively reduces the friction resistance between the paper and the limiting plate, thereby avoiding the phenomenon that the side of the paper is scratched or fluffed by the limiting plate; the setting of the over-roller enables the paper to be repeatedly bent by multiple over-rollers before entering the bottom of the pressure plate after being released from the paper roll, so that the paper can be relatively flat when entering the lower surface of the pressure plate, thereby effectively avoiding the phenomenon that the paper is creased when the pressure plate is pressed due to excessive bending of the paper; the setting of the roller makes it difficult for the paper to directly contact the frame, which can effectively avoid the phenomenon that the paper is scratched or fluffed by the frame body of the frame; the setting of the guide cylinder and the limiting rod facilitates the guiding and limiting of the pressure plate, thereby avoiding the pressure plate from shaking randomly due to the spring, and ultimately causing the pressure plate to be unable to press the paper accordingly.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-7A feeding mechanism of a servo-controlled high-speed paper container forming machine comprises a frame 1, a paper roll 2 is installed at the feeding end of the frame 1, and the paper roll 2 is a common reel with paper to be processed wound outside, that is, in the paper container production process, personnel can replace it regularly, and a motor 7 for driving the paper roll 2 to rotate is installed on the rear side of the feeding end of the frame 1, and the motor 7 is a common rotary driving power part with servo control effect, so that the unwinding speed of the paper on the paper roll 2 can be accurately controlled, and the paper wound on the paper roll 2 moves toward the discharging end of the frame 1 until it is finally moved into the external paper container forming machine, and the discharging end of the frame 1 is provided with a matching clamping limit assembly corresponding to the paper, and an electric cylinder 3 is provided above the middle part of the frame 1, and a linkage plate 4 is installed at the output end of the electric cylinder 3, and a plurality of springs 5 ​​are provided on the lower surface of the linkage plate 4 and are jointly at the lower end of the spring 5. A pressure plate 6 is connected, and the lower surface of the pressure plate 6 abuts against the surface of the paper located on the upper surface of the middle part of the frame 1. The clamping and limiting assembly includes a left-handed and right-handed threaded rod 8, a guide rod 9 and a limiting plate 10. The upper ends of the limiting plates 10 are respectively located on both sides of the paper. The left-handed and right-handed threaded rod 8 and the guide rod 9 are respectively installed on the lower ends of the limiting plates 10 by means of threads and sliding insertion. Both ends of the left-handed and right-handed threaded rod 8 and the guide rod 9 are installed at the end of the discharge end of the frame 1. The setting of the clamping and limiting assembly allows personnel to drive the left-handed and right-handed threaded rod 8 to rotate by rotating the hand wheel, and the left-handed and right-handed threaded rod 8 rotates to drive the two limiting plates 10 to approach or move away from each other. In this process, the two limiting plates 10 can be controlled to abut against both sides of the paper respectively, so as to limit and clamp the paper, thereby avoiding the shaking of the paper and causing inconvenience in subsequent production.

[0028] Example 2

[0029] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] Hand wheels are installed at both ends of the left and right threaded rods 8. Rollers 11 are provided at the upper ends of the limit plates 10 and contact the two sides of the paper through the rollers 11. The setting of the rollers 11 changes the contact between the limit plates 10 and the paper from sliding friction to rolling friction, that is, effectively reduces the friction resistance between the paper and the limit plates 10, thereby avoiding the side edges of the paper being scratched or fluffed by the limit plates 10; a plurality of rollers 12 are provided on the inner side of the frame body near the feed end of the frame 1, and the paper is wound on the surfaces of the plurality of rollers 12. The setting of the rollers 12 ensures that after the paper is released from the paper roll 2, before entering under the pressure plate 6, the paper will be repeatedly bent by a plurality of rollers 12, so that the paper can be relatively flat when entering the lower surface of the pressure plate 6, thereby effectively avoiding the phenomenon that the paper is creased when the pressure plate 6 is pressed due to excessive bending of the paper; the frame 1 is located at Rollers 13 are installed on both sides of the frame between the several rollers 12 and the discharging end. The setting of the rollers 13 makes it difficult for the paper to come into direct contact with the frame 1, which can effectively prevent the paper from being scratched and fluffed by the frame 1; the four corners of the lower surface of the pressure plate 6 are fixed with limit rods 14, and the front and rear sides of the frame 1 are provided with matching guide cylinders 15 corresponding to the limit rods 14. The setting of the guide cylinder 15 and the limit rod 14 is convenient for guiding and limiting the pressure plate 6, thereby preventing the pressure plate 6 from shaking randomly due to the spring 5, and finally causing the pressure plate 6 to be unable to press the paper accordingly; the upper side of the frame 1 is connected to a mounting cylinder 16, the electric cylinder 3 is mounted on the upper end of the mounting cylinder 16, and the linkage plate 4 is slidably mounted on the lower end inside the mounting cylinder 16. The setting of the mounting cylinder 16 is convenient for providing a guiding and limiting effect to the linkage plate 4, which further improves the stability of the entire feeding mechanism.

[0031] Principle and advantages of use: During the use of the utility model, the mechanism is installed on an external servo-controlled high-speed paper container forming machine, and then during the paper container production process, the personnel install the paper roll on the feeding end of the frame 1, and the paper passes through each part in turn to reach the discharging end of the frame 1, and finally enters the forming machine for paper container production; and in the above process, since there is a gap in the paper container production process, and then in this gap, the output end of the electric cylinder 3 extends, that is, the output end of the electric cylinder 3 pushes the linkage plate 4 to move downward, and the linkage plate 4 pushes the pressure plate 6 to move downward, until finally the pressure plate 6 tightly presses the paper below On the upper surface, the paper is flattened under the pressure of the electric cylinder 3, thereby avoiding the phenomenon that the paper is wrinkled and bent when it enters the paper container forming machine later, which leads to errors in the production of paper containers; and because a spring 5 is provided between the linkage plate 4 and the pressure plate 6, the personnel can control the pressure of the pressure plate 6 on the paper by controlling the extension distance of the output end of the electric cylinder 3, thereby adapting to papers of different thicknesses and different pressure requirements, that is, when the material used for this batch of paper containers has a large pressure tolerance, the extension distance of the output end of the electric cylinder 3 can be controlled to increase, and when the pressure tolerance of the paper is small, the extension distance of the electric cylinder 3 can be shortened.

[0032] At the same time, in the above process, by setting the clamping and limiting assembly, the personnel can control the distance between the two rollers 11 by turning the threaded rod 8 left and right, so as to facilitate the limiting and clamping of the front and rear edges of the paper by the two rollers 11, thereby avoiding the phenomenon of paper deviation. Also, due to the rolling friction between the rollers 11 and the paper, the phenomenon of the edge of the paper being scratched and fluffed is effectively avoided.

[0033] It should be further explained that the setting of the roller 11 changes the contact between the limit plate 10 and the paper from sliding friction to rolling friction, that is, effectively reduces the friction resistance between the paper and the limit plate 10, thereby avoiding the side of the paper being scratched or fluffed by the limit plate 10; the setting of the roller 12 makes the paper pass through multiple rollers 12 for repeated bending before entering the bottom of the pressure plate 6 after being released from the paper roll 2, so that the paper can be relatively flat when entering the lower surface of the pressure plate 6, thereby effectively avoiding the crease of the paper when the pressure plate 6 is pressed due to excessive bending of the paper. The setting of the roller 13 makes it difficult for the paper to come into direct contact with the frame 1, which can effectively prevent the paper from being scratched and fluffed by the frame 1; the setting of the guide cylinder 15 and the limiting rod 14 is convenient for guiding and limiting the pressure plate 6, thereby preventing the pressure plate 6 from shaking randomly due to the spring 5, and ultimately causing the pressure plate 6 to be unable to press the paper accordingly; the linkage plate 4 is installed at the upper end of the mounting cylinder 16, and the linkage plate 4 is slidably installed at the lower end of the mounting cylinder 16. The setting of the mounting cylinder 16 is convenient for providing a guiding and limiting effect to the linkage plate 4, which further improves the stability of the entire feeding mechanism.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
