Description

Technical Field

[0001] This utility model relates to the field of packaging carton manufacturing equipment, and in particular to a paper separator with automatic feeding function. Background Technology

[0002] Paper slitting machines are core equipment in the production of packaging cartons. They are mainly used to cut large-format cardboard or corrugated paper into semi-finished products of specific widths and lengths to meet the needs of subsequent printing, die-cutting, forming and other processes.

[0003] A Chinese utility model patent with authorization announcement number CN208700147U discloses a paper slitting machine, including a machine body with an inlet and an outlet. Three sets of rotating shafts are arranged sequentially and at intervals along the machine body from the inlet to the outlet: a pre-pressing shaft, a slitting shaft, and a groove pressing shaft. Two of the pre-pressing shafts, the slitting shaft, and the groove pressing shaft in each set are arranged vertically and rotate in opposite directions. A pre-pressing roller is mounted on the pre-pressing shaft, a slitting knife is mounted on the slitting shaft, and a groove pressing wheel is mounted on the groove pressing shaft. A feeding table is provided at the inlet end of the machine body, and a receiving box is provided at the outlet end. The pre-pressing shaft adjusts the feeding state of the paperboard, the slitting knife slits the paperboard, and the groove pressing wheel rolls and presses folding grooves into the paperboard.

[0004] Regarding the aforementioned technologies, it is necessary to manually feed the cardboard into the paper slitting machine for cutting and creasing. The inventor believes that this has drawbacks such as inconvenient feeding and low work efficiency.

[0005] In view of the above, it is necessary to improve the existing technology to solve the above problems. Utility Model Content

[0006] The present invention aims to provide a filter for treating organic waste gas to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A paper slitting machine with automatic feeding function includes a frame, a receiving box and an operating table connected to both sides of the frame, the receiving box having a receiving port, a slitting shaft rotatably connected to the frame, a slitting blade connected to the slitting shaft, two slitting shafts arranged vertically and rotating in opposite directions, a paper slitting slot on the operating table, a first fixed block and a second fixed block connected to the operating table, the first fixed block and the second fixed block being connected to the same second slide rod, the second slide rod being slidably connected to a sleeve, the sleeve being connected to a first slide rod, the first slide rod being slidably connected to a slider, the slider being connected to a toggle plate, the toggle plate being connected to a toggle rod, the toggle rod being slidably connected to the paper slitting slot, a mounting frame connected to the frame, a motor connected to the mounting frame, a rotating block rotatably connected to the output end of the motor, a rotating rod slidably connected to the rotating block, a spring sleeved on the rotating rod, the two ends of the spring being connected to the rotating block and a rotating plate respectively, the rotating rod being connected to a rotating plate, and the rotating plate being rotatably connected to the slider.

[0009] Preferably, the operating table is connected to four columns, each with an L-shaped cross-section. The columns are located on both sides of the paper separating groove and are symmetrically distributed inwards. A crossbar connects the columns, and each column has a paper outlet. The vertical height of the paper outlet is between the thickness of a single sheet of paperboard and the sum of the thicknesses of two sheets of paperboard.

[0010] Preferably, the frame is rotatably connected to two preload shafts, each preload shaft is connected to a preload wheel, and the two preload shafts are distributed vertically and rotate in opposite directions.

[0011] Preferably, the frame is rotatably connected to two grooving shafts, each grooving shaft is connected to a grooving wheel, and the two grooving shafts are distributed vertically and rotate in opposite directions.

[0012] Preferably, the operating table is symmetrically equipped with guide rods, which are arranged symmetrically about the center line of the operating table.

[0013] Preferably, a dust collection box is provided below the slitting shaft to collect paper scraps generated during slitting.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0015] The rotating block driven by the motor drives the rotating plate to swing. With the help of spring buffer and slider and slide rod transmission mechanism, the actuating rod slides back and forth along the paper separating groove. This makes the actuating rod achieve low-vibration linear reciprocating motion in the paper separating groove, ensuring that the paperboard separating action is smooth and reliable, effectively maintaining the stability of continuous feeding, and avoiding jamming caused by mechanical impact. It realizes automatic paperboard separating and feeding, eliminating the need for manual pushing of each sheet, significantly improving feeding efficiency and reducing labor intensity.

[0016] The combination of the L-shaped uprights and the height-limiting paper outlet forms a rigid guide frame, which achieves stable separation of single sheets of paperboard through two-point positioning constraints and gap control.

[0017] The upper and lower pre-compression roller sets adopt a constant pressure counter-rolling design to achieve dynamic stress elimination during the paperboard conveying process. The symmetrically distributed pre-compression contact surfaces correct the warping deformation of the paperboard, providing a flat and stable processing base surface for subsequent slitting processes.

[0018] The phase synchronization control system of the groove pressing wheel group ensures precise matching of the linear speeds of the upper and lower wheels, avoiding crease offset defects caused by paperboard displacement during the groove pressing process, and at the same time assisting the slit paper to smoothly enter the collection box.

[0019] The progressive channel formed by the dual guide rods forms a spatial posture correction system. Through the dynamic friction balance of the edge contact surface, it corrects the deviation of the cardboard travel angle in real time, ensuring the coincidence of the cardboard centerline and the blade assembly reference plane during the slitting process.

[0020] A movable dust collection box is installed directly below the slitting blade assembly. Its open structure completely covers the slitting area, and the dust and debris are collected by gravity settling, effectively preventing paper scraps from scattering and polluting the processing environment.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figures 1 to 3The paper slitting machine shown includes a frame, such as... Figure 1 As shown, a receiving box and an operating table are connected to both sides of the frame, respectively. The operating table is equipped with a paper separating slot, a first fixing block is connected to the bottom of the operating table, and a second fixing block is connected to the side wall of the operating table. Figure 2 As shown, the first and second fixed blocks are connected to both ends of the second slide rod. The second slide rod is slidably connected to a sleeve, and the bottom of the sleeve is connected to the first slide rod. The first slide rod is slidably connected to a slider, which is connected to a toggle plate. The toggle plate has an inverted L-shaped longitudinal section, and a toggle rod is connected to the top of the toggle plate. The top of the toggle rod is located above the side wall of the operating table. A mounting bracket is connected to the lower surface of the frame, and a motor is connected to the mounting bracket. A rotating block is rotatably connected to the motor output end. A rotating rod is slidably connected to the rotating block, and a rotating plate is connected to the rotating rod. A spring is sleeved on the rotating rod, and both ends of the spring are connected to the rotating block and the rotating plate, respectively. The rotating plate is rotatably connected to the slider. Figure 1 As shown, the operating table is connected to four L-shaped columns. These four columns are located on both sides of the paper separating trough and are symmetrically distributed inwards towards the center. Crossbars connect the columns. Figure 1 and Figure 3 As shown, a paper outlet is provided between the uprights, and the vertical height of the paper outlet is adapted according to the thickness of the paper being processed.

[0027] Working Principle: When the motor is started, the motor output drives the rotating block to rotate. The rotating block drives the rotating rod to rotate. Under the action of the spring, the rotating rod is pushed away from the rotating block, simultaneously driving the rotating plate away from the rotating block. The rotating plate then drives the slider connected to it to move upwards along the second sliding rod. Due to the constraint of the sleeve, the slider drives the first sliding rod and the sleeve to move to the right along the second sliding rod. When the slider reaches the rightmost position, the rotating block continues to rotate, causing the slider to move downwards along the first sliding rod. When the slider reaches the preset lowest point, the rotating block continues to drive the rotating rod to rotate clockwise, driving the slider to move horizontally to the left. Simultaneously, the sleeve, constrained by the second sliding rod, drives the first sliding rod to move to the left as a whole. As the rotating block continues to rotate, it moves horizontally to the left along the second sliding rod under the limiting action of the sleeve. After the slider reaches the leftmost end, the rotating block continues to rotate. Under the push of the spring, the slider gradually reaches the top of the first sliding rod, causing the actuating rod to enter the paper separating slot. With the motor continuously working, the slider moves horizontally to the right, driving the actuating rod to move to the right. This linkage mechanism converts the rotational motion of the motor into the reciprocating stroke of a lever in a U-shape. The lever, located within the paper separating slot, alternately pushes against the edge of the cardboard, achieving the individual separation and feeding of stacked cardboard sheets. The operating table is connected to four L-shaped columns, symmetrically distributed on both sides of the paper separating slot, with crossbars connecting them. Figure 1 As shown, a paper outlet is provided between the uprights, and the vertical height of the paper outlet is adapted according to the thickness of the paper being processed.

[0028] like Figure 1As shown, the receiving box has a receiving port on the left side and an outward-opening cabinet door on the right side. Two slitting shafts are rotatably connected to the frame, each connected to a slitting blade. The two slitting shafts are vertically distributed and rotate in opposite directions. Pre-compression shafts and groove shafts are installed on the left and right sides of the slitting shafts, respectively. The pre-compression shafts and groove shafts are connected to pre-compression wheels and groove wheels, respectively. There are two pre-compression shafts and two groove shafts, both vertically distributed and rotating in opposite directions. Two guide rods are connected to the top surface of the operating table near the frame, symmetrically arranged about the center line of the operating table. A dust collection box for collecting debris is located below the slitting shafts.

[0029] Working Principle: After being guided by guide rods, the slit cardboard enters the grooved section. A motor drives two pre-pressing shafts to rotate in opposite directions, which in turn rotates the connected pre-pressing rollers, feeding the paper to the middle position between the two slitting blades. The motor then drives the slitting shaft to rotate, which in turn drives the connected slitting blades to rotate in opposite directions, completing the paper slitting. Simultaneously, the paper moves to the right, pushing it between the grooved rollers connected to the two grooved shafts. Meanwhile, debris and residue generated during slitting fall into the dust collection box below the slitting shafts under gravity. The grooved rollers smoothly transport the slit paper through the receiving port to the receiving hopper, where it is finally collected.

[0030] The specific implementation process is as follows:

[0031] After the workers stack the cardboard to be cut in the paper-feeding area enclosed by the uprights and crossbars, they start the motor. The rotating block rotates continuously under the drive of the motor. Through the elastic buffering effect of the spring, the rotating rod drives the rotating plate to swing in a regular manner. This swing is converted into horizontal and vertical reciprocating motion through the linkage mechanism of the slider and the slide rod, driving the sleeve to slide left and right along the second slide rod, and finally driving the actuating rod to move periodically in the paper-separating slot. The actuating rod slides regularly in the paper-separating slot, separating the stacked cardboard one sheet at a time. During the separation process, the guide frame formed by the L-shaped uprights restricts the passage of only one cardboard sheet through the paper outlet with a specific height gap. Double cardboard sheets are blocked because their thickness exceeds the gap. After the separated cardboard is corrected in direction by the guide rod, it enters the pre-pressure shaft area. The upper and lower pre-pressure rollers rotate in opposite directions, applying uniform pressure to the surface of the cardboard to eliminate bending deformation. Then the cardboard is fed into the slitting shaft area, where the slitting blades rotate in opposite directions to complete the cutting. At the same time, the debris generated by slitting falls into the dust collection box below. The cut cardboard continues to be conveyed to the groove pressing shaft, where the upper and lower groove pressing rollers press out crease lines with synchronous precision. Finally, the finished product slides into the receiving box through the receiving port. Throughout the process, workers only need to periodically replenish the cardboard stacks and monitor the equipment operation. The system achieves continuous automatic sheeting, flattening, cutting, and groove pressing through mechanical linkage, effectively solving the problems of low efficiency and unstable precision of manual feeding.
