Description

Technical Field

[0001] This invention relates to a cardboard processing machine, specifically a cardboard slotting machine. Background Technology

[0002] Cardboard boxes, cartons, and other paper packaging containers are generally made by folding cardboard along grooves. A cardboard slotting machine is a device for slotting cardboard. Existing cardboard slotting machines include a frame and a slotting mechanism. The slotting mechanism includes rollers, tension rollers, a pressure belt, and cutters. Cardboard is conveyed from the feed end of the slotting mechanism by the paper feeding mechanism. The pressure belt presses the cardboard onto the rollers. As the rollers rotate, the cutters slot the cardboard, creating a groove line X. After slotting, the cardboard exits from the discharge end of the slotting mechanism. To ensure accurate slotting, the cardboard needs to be corrected before entering the slotting mechanism. Therefore, a cardboard correction mechanism is installed at the feed end of the slotting mechanism. This mechanism includes a correction wheel and a correction plate. As the cardboard is conveyed forward on the feeding conveyor, the correction wheel presses against the cardboard, causing it to move to the side and approach the correction plate (the correction wheel is tilted to achieve correction). In this way, the cardboard enters the slotting mechanism with the side edge of the correction plate as a reference, thus determining the slotting position. However, due to the cardboard cutting process, the side edge of each batch of cardboard cannot be guaranteed to be straight. Figure 6 As shown, if the side of cardboard Z is a straight edge (the angle between the side and the bottom edge is 90°), then after the side of cardboard Z rests against the side of the alignment plate (i.e., it is flush with the reference line K of the alignment plate), the front edge of cardboard Z will also be flush with the roller reference line D of the roller. This allows the cardboard to stably enter the slotting mechanism, which meets the requirements. Figure 7 As shown, if the side of cardboard Z is a slanted side (the angle between the side and the bottom edge is not 90°, such as 88° in the figure), then after the side of cardboard Z rests against the side of the straightening plate (i.e., it is flush with the reference line K of the straightening plate), one corner G of the front edge of the cardboard will be at the very front (e.g., Figure 7 As shown), the slotting mechanism consists of a roller and a paper pressing belt forming an inlet (as shown). Figure 2 As shown in the image, the front corner of the cardboard will hit the roller or pressure belt first, forcing the cardboard to rotate. The angle of rotation is uncertain, so the position of the groove line cut after the cardboard enters the slotting mechanism is also uncertain, resulting in some cardboard having grooves that do not meet the requirements. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention innovatively provides a paperboard slotting machine with adjustable alignment that can improve the stability of slotting by adjusting the alignment of the paperboard.

[0004] This type of cardboard slotting machine with adjustable alignment includes a frame and a slotting mechanism. The infeed end of the slotting mechanism is equipped with a paper feeding conveyor and a cardboard alignment mechanism. The cardboard alignment mechanism includes an alignment guide plate. The cardboard alignment mechanism is mounted on a movable seat, which is slidably and adjustablely mounted on a transverse guide rail. The alignment guide plate can be horizontally rotated and adjusted via a pin.

[0005] The movable seat is equipped with a guide rail seat, and the guide rail seat is equipped with a laterally extending linear guide rail. An adjusting slider is slidably provided on the linear guide rail. The adjusting slider is connected to a rotary adjusting nut. The rotary adjusting nut is connected to a correction plate through a connector. The rotary adjusting nut is threadedly connected to a rotary adjusting screw.

[0006] The correction plate is connected to a longitudinally extending lower guide rail, and a sliding lower seat is slidably mounted on the lower guide rail. The sliding lower seat is connected to the connector.

[0007] The rotary adjustment lead screw is connected to the rotary adjustment power source, which is a servo motor.

[0008] The paper feeding and conveying mechanism is mounted on a movable base.

[0009] The movable seat is connected to the lateral adjustment power source that drives the movable seat to move on the lateral guide rail.

[0010] The movable seat is connected to the lateral adjusting nut, which is threaded onto the lateral adjusting screw. The lateral adjusting power source is driven by the lateral adjusting screw and is a servo motor.

[0011] The paper feeding and conveying mechanism is provided in multiple ways and arranged side by side. The movable seat is equipped with an adjustment guide rail, and the paper conveying mechanism is slidably mounted on the adjustment guide rail via an adjustment slide block.

[0012] A paper feeding mechanism is provided behind the paper feeding mechanism. The paper feeding mechanism includes a paper feeding conveyor belt. A discharge baffle is installed on one side of the paper feeding conveyor belt. The discharge baffle and the correction plate are separate structures.

[0013] The slotting mechanism includes a roller, a paper pressing belt, and a cutting tool.

[0014] According to the claim, the paperboard slotting machine with adjustable deviation correction is characterized in that: the paperboard deviation correction mechanism includes a deviation correction wheel, which is located above the paper feed conveyor belt.

[0015] According to the present invention, a cardboard slotting machine with a correction adjustment mechanism is provided. By rotating and adjusting the correction plate, and simultaneously moving the correction plate left and right, the front edge of the cardboard can always be aligned with the baseline of the roller, thereby ensuring that the cardboard will not rotate when it enters the slotting mechanism and improving the slotting stability.

[0024] like Figure 1 As shown, this type of cardboard slotting machine with web guiding adjustment includes a frame and a slotting mechanism 4, such as... Figure 2 As shown, the grooving mechanism 4 includes a roller 40, a pressure belt 41, and a cutter 42. The pressure belt 41 is attached to the roller 40 under the action of the tension roller 43. The cardboard enters through the inlet between the roller 40 and the pressure belt 41. After being pressed between the roller 40 and the pressure belt 41, the cardboard moves as the roller 40 rotates. The cutter 42, located on one side of the roller 40, grooves the cardboard. This is existing technology.

[0025] like Figure 1 As shown, in order to feed the cardboard into the slotting mechanism 4 and simultaneously correct its deviation, the present invention provides a paper feeding conveying mechanism 2 and a cardboard deviation correction mechanism 3 (both of which are prior art) at the feeding end of the slotting mechanism 4. Figure 2As shown, the paper feeding conveyor 2 includes a paper feeding conveyor belt 20 (or a conveyor roller structure), while the paperboard correction mechanism 3 includes a correction wheel 30 and a correction plate 31. The correction wheel 30 is located above the paper feeding conveyor belt 20. The paperboard is conveyed forward on the paper feeding conveyor belt 20. Because the correction wheel 30 presses down on the paperboard from above, the paperboard is pushed to the side by the correction wheel 30, and finally rests against the inner side of the correction plate 31. Thus, the paperboard enters the slotting mechanism 4 along the inner side of the correction plate 31. To solve the technical problems mentioned in the background art, the present invention mounts the paperboard correction mechanism 3 on a movable base 5, such as... Figure 3 As shown, the movable seat 5 is slidably and adjustablely mounted on the transverse guide rail 6; in addition, the correction plate 31 can be horizontally rotated and adjusted via the pin 32.

[0026] The correction principle of this type of cardboard slotting machine is as follows: Figure 8 As shown, if one batch of cardboard has a beveled side, the angle and position of the alignment plate 31 need to be adjusted. First, adjust the alignment plate 31 to rotate horizontally around the pivot 32, so that the cardboard Z rests against the alignment plate 31 (i.e., flush with the alignment plate 31's reference line K), ensuring the front edge of the cardboard Z is parallel to the roller reference line D of the roller 40. Then, drive the movable seat 5 to move on the transverse guide rail 6, thus moving the alignment plate 31 left and right. After the left and right positions of the alignment plate 31 are determined, the cardboard Z, under the action of the alignment wheel, rests against the alignment plate 31 again, aligning the groove line X required for the cardboard to be slotted with the cutter 42 when it enters the slotting mechanism 4. This allows the cardboard Z to be slotted as follows: Figure 8 The cardboard enters the slotting mechanism 4 at the position shown. Since the front edge of the cardboard is parallel to the roller reference line D of the roller 40, when the cardboard Z enters between the roller 40 and the pressure belt 41, the roller 40 and the pressure belt 41 can just press down on the front edge of the cardboard Z, allowing the cardboard Z to move with the rotation of the roller 40. In this way, the cardboard Z will not rotate, and the position of the slotted line X of the cardboard is more stable.

[0027] To enable the correction plate 31 to rotate horizontally around the pin 32, the present invention includes a guide rail seat 33 mounted on the movable seat 5, and a laterally extending linear guide rail 34 mounted on the guide rail seat 33. An adjusting slider 35 is slidably mounted on the linear guide rail 34, and this adjusting slider 35 is connected to a rotating adjusting nut 36. The rotating adjusting nut 36 is connected to the correction plate 31 via a connecting piece 37, and is threadedly connected to a rotating adjusting screw 38. By rotating the rotating adjusting screw 38, the rotating adjusting screw 38 drives the rotating adjusting nut 36 to move along the linear guide rail 34. The rotating adjusting nut 36, in turn, drives the correction plate 31 to move via the connecting piece 37. Thus, the correction plate 31 can rotate horizontally around the pin 32, thereby achieving angle adjustment.

[0028] Since the alignment guide plate 31 rotates horizontally around the pin 32, any point on the alignment guide plate 31 moves along an arc trajectory. For small adjustment angles, the above adjustment method can be used. However, for larger adjustment angles, the arc trajectory of the alignment guide plate 31 needs to be considered. Therefore, as follows... Figure 4 As shown, the present invention also includes a longitudinally extending lower guide rail 370 connected to the alignment plate 31. A sliding lower seat 371 is slidably mounted on the lower guide rail 370 and is connected to the connector 37. With this structure, when the alignment plate 31 rotates at a large angle, the lower guide rail 370 on the alignment plate 31 will move relative to the sliding lower seat 371, that is, the rotating adjusting nut 36 is flexibly connected to the alignment plate 31, preventing them from jamming.

[0029] To facilitate adjustment of the rotation of the alignment guide plate 31, the rotary adjustment screw 38 of this invention is connected to the rotary adjustment power source 39, which is a servo motor. Driven by the rotary adjustment power source 39, the rotary adjustment screw 38 rotates, thereby causing the alignment guide plate 31 to rotate. Of course, the rotary adjustment screw 38 can also be rotated manually. Both methods fall within the scope of protection of this invention.

[0030] Similarly, to facilitate the adjustment of the left and right movement of the correction plate 31, the movable seat 5 is connected to the lateral adjustment power source 9, which drives the movable seat 5 to move on the lateral guide rail 6. Driven by the lateral adjustment power source 9, the movable seat 5 moves left and right. Of course, the movable seat 5 can also be moved manually. Both are within the scope of protection of this invention.

[0031] To facilitate the movement of the movable seat 5, the movable seat 5 is connected to a lateral adjusting nut, which is threaded onto a lateral adjusting screw 7. A lateral adjusting power source 9, which is a servo motor, is connected to the lateral adjusting screw 7. Driven by the lateral adjusting power source 9, the lateral adjusting screw 7 rotates, causing the lateral adjusting nut and the movable seat 5 to move together.

[0032] By adopting the power source driven adjustment method, the parameters to be adjusted are simply input into the power source controller, which controls the rotation adjustment power source 39 to adjust the angle of the correction plate 31, and the lateral adjustment power source 9 to adjust the position of the correction plate 31. Finally, the cardboard is corrected and enters the slotting mechanism 4, making it easier for ordinary workers to adjust.

[0033] To facilitate the alignment of the cardboard with the cutter 42 in the left-right direction, the paper feeding mechanism 2 of this invention is also mounted on the movable seat 5. When the movable seat 5 moves, the paper feeding mechanism 2 and the alignment guide plate 31 move left and right together. After the alignment guide plate 31 is rotated and adjusted to the correct angle, the alignment guide plate 31 and the movable seat 5 move left and right as a whole, which makes calibration more convenient.

[0034] In order to meet the needs of conveying cardboard of different sizes, such as Figure 5 As shown, the paper feeding and conveying mechanism 2 of the present invention has multiple components arranged side by side, and an adjustment guide rail 8 is installed on the movable seat 5. The paper feeding mechanism 2 is slidably mounted on the adjustment guide rail 8 via an adjustment slide. When the size of the paperboard changes, the positions of the multiple paper feeding and conveying mechanisms 2 need to be adjusted to adapt to the conveying surface width of the paperboard of that size. The adjustment is very convenient; simply move the paper feeding mechanism 2 on the adjustment guide rail 8.

[0035] Finally, it is worth mentioning that a paper feeding mechanism 1 is located behind the paper feeding mechanism 2. Many sheets of cardboard are stacked on this paper feeding mechanism 1. The paper feeding mechanism 1 includes a paper feeding conveyor belt 10, which feeds the cardboard sheets one by one onto the paper feeding mechanism 2. A discharge baffle 12 is installed on one side of the paper feeding conveyor belt 10. The discharge baffle 12 can block the paper stack from the side, keeping it to the side. In existing systems, the discharge baffle 12 is connected to the alignment guide plate 31. The problem with this structure is that when the cardboard stack rests against the discharge baffle 12, it vibrates. This vibration is transmitted to the alignment guide plate 31, affecting the alignment of the cardboard. To solve this problem, the discharge baffle 12 and the alignment guide plate 31 of this invention are separate structures. This way, the vibration of the discharge baffle 12 will not affect the alignment guide plate 31, ensuring that the alignment of the cardboard is not affected.
