Abstract
Description
Technical Field
[0001] This utility model relates to the field of correction device technology, specifically a corrugated cardboard correction device. Background Technology
[0002] During the slitting or printing process of corrugated cardboard, the deviation of the corrugated cardboard during transmission has many adverse effects on the processing. Therefore, it is necessary to use a correction device to correct the deviation of the cardboard during transmission and ensure the processing quality of corrugated cardboard slitting or printing.
[0003] To improve the alignment effect during corrugated cardboard conveying, existing technologies have made numerous improvements to corrugated cardboard alignment devices. For example, patent publication number CN220906688U discloses a corrugated cardboard alignment device including a support base. A conveyor belt is movably connected to the upper surface of the support base. Mounting frames are fixedly installed on both sides of the center of the support base, with the two mounting frames located on the left and right sides of the conveyor belt. This corrugated cardboard alignment device, through the action of a motor, threaded rod, connecting block, slider one, and fixed frame, allows the distance between the two rollers to be adjusted as needed. Furthermore, the action of slider two and slide rails makes the fixed frame and limiting plates move more stably. Because the two limiting plates are funnel-shaped, the corrugated cardboard can be corrected to the center line of the conveyor belt as it moves. The limiting springs provide cushioning during the correction of the corrugated cardboard, thus preventing deformation.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
[0005] The aforementioned comparative document describes the use of two sets of limiting plates to correct the deviation of corrugated cardboard on the conveyor belt. However, in reality, after being cut, the corrugated cardboard is also conveyed by the conveyor belt. If the conveyor belt in the aforementioned comparative document is used to convey the cut corrugated cardboard, the cut cardboard may deviate significantly before reaching the position of the limiting plates. If the cardboard falls off the conveyor belt before reaching the position of the limiting plates, the correction effect of the corrugated cardboard is reduced. Therefore, there is an urgent need in the art to improve the corrugated cardboard correction device to overcome the shortcomings of the prior art. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example 1
[0030] Please see Figures 1-6 A corrugated cardboard alignment device includes two symmetrical support brackets 1, a conveyor belt 2 for conveying corrugated cardboard between the two support brackets 1, two inverted U-shaped mounting brackets 3 located at both ends of the two support brackets 1, mounting units 4 for fixed installation between the two ends of the two mounting brackets 3 and the support brackets 1, two alignment plates 5 abutting against the upper side of the conveyor belt 2 between the two mounting brackets 3, two symmetrical sliding blocks 6 slidably connected to the inner top wall of each of the two mounting brackets 3, the alignment plates 5 being located between the two sliding blocks 6, a sliding groove 7 adapted to the sliding blocks 6 being opened in the inner top wall of the mounting bracket 3, a bidirectional lead screw 8 being rotatably connected in the sliding groove 7, a drive motor 9 whose output end is fixedly connected to one end of the bidirectional lead screw 8 being fixedly installed on one side of the mounting bracket 3, the bidirectional lead screw 8 passing through the two sliding blocks 6 and being threadedly connected to the two sliding blocks 6, the bidirectional lead screw 8 driving the two sliding blocks 6 to move towards or away from each other when rotating, and a number of ball bearings 22 embedded on the facing sides of the two alignment plates 5.
[0031] The specific implementation method in this embodiment is as follows: The conveyor belt 2 is a known prior art technology. The conveyor belt 2 is sleeved between the sides of two drive rollers. The drive rollers are driven by a motor to rotate and transmit power to the conveyor belt 2. When the cut corrugated cardboard is conveyed by the conveyor belt 2, two mounting brackets 3 are installed on the support bracket 1 by the mounting unit 4. The lower side of the correction plate 5 abuts against the upper side of the conveyor belt 2. When it is necessary to correct the corrugated cardboard on the conveyor belt 2, the drive motors 9 are started. The two drive motors 9 are synchronous motors. The output end of the drive motors 9 drives the bidirectional lead screw 8 to rotate. The teeth on the side of the bidirectional lead screw 8 are opposite and symmetrical. When the bidirectional lead screw 8 rotates, it drives the sliding block 6 to move in opposite directions. When the sliding block 6 moves, it drives the two correction plates 5 to rotate. The two guide plates 5 move towards each other, pushing the corrugated cardboard towards the center of the conveyor belt 2, thereby achieving the effect of correcting the corrugated cardboard's deviation. The starting position of the two guide plates 5 can be determined by the drive motor 9, and the two guide plates 5 can be adjusted according to the width of the conveyor belt 2 or the width of the corrugated cardboard. The distance between the two guide plates 5 can be adjusted to match the width of the corrugated cardboard. When the corrugated cardboard is conveyed on the conveyor belt 2, there is no need to correct its deviation. The corrugated cardboard slides on the side of the ball bearing 22, reducing the coefficient of friction during the conveying of the corrugated cardboard and improving the efficiency of the conveying. Furthermore, the device can be installed on the existing support bracket 1 through the mounting unit 4, improving the overall applicability of the device.
[0032] The drive motor 9 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be repeated in the specification. The drive motor 9 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power connection line. The main controller can be a conventional known device such as a computer that plays a control role.
[0033] Example 2
[0034] Please see Figure 1 , Figure 3 and Figure 4 This embodiment includes the above embodiment, wherein the installation unit 4 includes a first adjusting bolt 10 that passes through and is threaded to both sides of the mounting frame 3. One end of the first adjusting bolt 10 is rotatably connected to a clamping plate 11, and the side of the first adjusting bolt 10 is threadedly connected to a first limiting nut 12. Both sides of the mounting frame 3 have a storage groove 23 adapted to the clamping plate 11. The clamping plate 11 is L-shaped and adapted to the bearing bracket 1.
[0035] In this embodiment, the specific implementation method is as follows: When the mounting bracket 3 needs to be installed on the support bracket 1, the first adjusting bolt 10 is rotated, and the first adjusting bolt 10 drives the abutment plate 11 to abut against the side of the support bracket 1. The upper part of the abutment plate 11 is engaged with the upper part of the support bracket 1. The first limiting nut 12 is tightened to limit and fix the position of the first adjusting bolt 10. The storage groove 23 is used to store the abutment plate 11 when not in use. The mounting bracket 3 can be installed above the conveyor belt 2 of different widths, thereby improving the applicability of the overall device.
[0036] Example 3
[0037] Please see Figures 3-6 This embodiment includes all the above embodiments, and further includes: a sliding groove 7 penetrating the upper side of the mounting bracket 3; a second adjusting bolt 13 penetrating and threadedly connected to the sliding block 6; a correction plate 5 located below the second adjusting bolt 13; a second limiting nut 14 threadedly connected to the side of the second adjusting bolt 13; plug-in blocks 15 fixedly connected to the upper sides of both ends of the correction plate 5; a connecting bracket 16 rotatably connected to the lower end of the second adjusting bolt 13; a plug-in groove 17 adapted to the plug-in block 15 penetrating one side of the connecting bracket 16; a quick-fixing unit provided for the connecting bracket 16 and the plug-in block 15; a limiting rod 18 penetrating one side of the connecting bracket 16; a limiting hole 19 adapted to the end of the limiting rod 18 on one side of the plug-in block 15; a pull plate 20 fixedly connected to one end of the limiting rod 18; and a spring 21 sleeved on the side of the limiting rod 18 fixedly connected between the pull plate 20 and one side of the connecting bracket 16.
[0038] In this embodiment, the height of the correction plate 5 can be adjusted by rotating the second adjusting bolt 13, which is suitable for bearing brackets 1 of different heights. After adjusting the height of the correction plate 5, the second limiting nut 14 is tightened to limit the position of the second adjusting bolt 13. The correction plate 5 can be installed between the two connecting brackets 16 through the fixing unit, so that the whole device can be disassembled, which is convenient for the transportation and installation of the whole device. When installing the correction plate 5, the pull plate 20 is pulled away from the connecting bracket 16. The pull plate 20 drives the limiting rod 18 to move. At this time, the spring 21 is stretched, and the plug-in blocks 15 on both sides of the correction plate 5 are inserted into the plug-in slots 17 on the connecting bracket 16. After the plug-in blocks 15 are fully inserted into the plug-in slots 17, the pull plate 20 is released. At this time, the spring 21 is contracted, which drives one end of the limiting rod 18 to be inserted into the limiting hole 19, which is convenient for the installer to install or disassemble the correction plate 5 later.
