Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, and in particular to a stacking cardboard alignment device. Background Technology
[0002] Currently, in the fields of cardboard box production and packaging, the alignment of stacked cardboard typically relies on manual operation or complex mechanical devices. Traditional methods suffer from low efficiency, unstable alignment accuracy, and high labor intensity. Some existing devices use a single-sided adjustment mechanism, resulting in poor synchronization of the two side limit plates, which can easily cause cardboard misalignment or damage. In addition, manual adjustment methods are difficult to adapt to the need for rapid switching between different sizes of cardboard, thus hindering the improvement of production efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a stacking cardboard alignment device. To achieve the above objectives, this utility model adopts the following technical solution:
[0004] A stacking cardboard alignment device, comprising:
[0005] Mounting bracket, comprising two mounting plates arranged side by side;
[0006] Two fixing rods are fixedly connected between two mounting plates and are arranged vertically side by side;
[0007] Two sliding rods are arranged side by side, one end of which is slidably connected to two fixed rods, and the other end of which is fixedly connected to a limiting plate. The limiting plate is arranged opposite to the sliding rods to limit the stacking of cardboard.
[0008] The adjusting rod is rotatably mounted between two mounting plates. The middle section of the adjusting rod is symmetrically provided with reverse threads, and two sliding rods are symmetrically threaded onto the adjusting rod.
[0009] Furthermore, both ends of the adjusting rod are fixedly connected to rotating disks for rotating the adjusting rod.
[0010] Furthermore, the rotating disk is fixedly connected to several levers arranged in a circular array.
[0011] Furthermore, a locking disc is threaded onto the adjusting rod, and the locking disc is located on the outside of the mounting plate.
[0012] Furthermore, a threaded cylinder is fixedly connected to the sliding rod, and the threaded cylinder is threadedly connected to the adjusting rod.
[0013] Furthermore, the fixing rod is provided with a groove, and the groove is provided with a scale.
[0014] Furthermore, a sliding block is slidably connected to the fixed rod, and the sliding rod is fixedly connected to the sliding block by bolts.
[0015] Furthermore, a U-shaped groove is fixedly connected to the limiting plate, and the groove is fixed to the sliding rod by bolts.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The reverse thread design of the adjusting rod drives the two sliding rods to move synchronously in opposite directions or in opposite directions, ensuring symmetrical adjustment of the limit plates on both sides and significantly improving the alignment accuracy of the cardboard.
[0018] 2. The spacing between the limit plates can be quickly adjusted by rotating the adjusting rod, eliminating the need for manual calibration on each side, and making it suitable for efficient switching between multiple cardboard specifications;
[0019] 3. The vertical sliding cooperation between the fixed rod and the sliding rod enhances the rigidity of the device. The limiting plate acts directly on the edge of the cardboard, reducing the risk of offset. Alignment can be completed simply by rotating the adjusting rod, reducing manual intervention and improving production efficiency. Attached Figure Description
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] Figure 1 This is a schematic diagram of the main structure of an embodiment of the present utility model;
[0022] Figure 2 This is a top view of an embodiment of the present invention.
[0023] In the above attached figures: mounting plate 1, fixing rod 2, sliding rod 3, limiting plate 4, adjusting rod 5, rotating disc 6, hand lever 7, locking disc 8, threaded cylinder 9, groove 10, sliding block 11, and slot 12. Detailed Implementation
[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0025] This utility model provides, for example Figure 1 , Figure 2 A stacked cardboard alignment device is shown, comprising:
[0026] Mounting bracket, including two mounting plates 1 arranged side by side;
[0027] Two fixing rods 2 are fixedly connected between two mounting plates 1 and are arranged vertically side by side;
[0028] Two sliding rods 3 are arranged side by side, one end of which is slidably connected to two fixed rods 2, and the other end of which is fixedly connected to a limiting plate 4. The limiting plate 4 is arranged opposite to the sliding rods 3 to limit the stacked cardboard.
[0029] Adjusting rod 5 is rotatably mounted between two mounting plates 1. The middle section of adjusting rod 5 is symmetrically provided with reverse threads, and two sliding rods 3 are symmetrically threaded onto adjusting rod 5.
[0030] The working principle is as follows: When it is necessary to adjust the alignment of the stacked cardboard, rotating the adjusting rod 5 causes the reverse thread in its middle section to drive the sliding rods 3 on both sides to move synchronously towards or away from each other along the fixed rod 2. The sliding rods 3 move the limiting plates 4 closer to or further away, thereby limiting the stacking width of the cardboard. Due to the symmetrical thread design of the adjusting rod 5, the limiting plates 4 on both sides always maintain synchronous movement, ensuring that the edges of the cardboard are parallel and aligned. In this way, the device can quickly adapt to cardboard of different sizes and maintain a stable limiting state under the action of gravity or external force.
[0031] In this embodiment, as Figure 1 , Figure 2 As shown, both ends of the adjusting rod 5 are fixedly connected to rotating disks 6 for rotating the adjusting rod 5. The distance between the limiting plates 4 can be adjusted by rotating either end of the rotating disk 6, making it convenient for a single operator to use.
[0032] In this embodiment, as Figure 1 , Figure 2 As shown, several levers 7 arranged in a circular array are fixedly connected to the rotating disk 6. This makes it easier and less strenuous for the operator to rotate the adjusting lever 5.
[0033] In this embodiment, as Figure 1 , Figure 2 As shown, a locking disc 8 is threaded onto the adjusting rod 5, and the locking disc 8 is located on the outside of the mounting plate 1. By rotating the locking disc 8 against the mounting plate 1, the adjusting rod 5 is locked, thereby fixing the position of the two limiting plates 4, which facilitates the neat and orderly placement of stacks of cardboard.
[0034] In this embodiment, as Figure 1 , Figure 2 As shown, a threaded cylinder 9 is fixedly connected to the sliding rod 3, and the threaded cylinder 9 is threadedly connected to the adjusting rod 5. The engagement of the threaded cylinder 9 with the adjusting rod 5 facilitates the stable driving of the sliding rod 3 by the adjusting rod 5, thereby improving the accuracy of the equipment.
[0035] In this embodiment, as Figure 1 As shown, the fixing rod 2 is provided with a groove 10, and the groove 10 is provided with a scale. The distance between the two limiting plates 4 can be accurately determined by the scale, and quick adjustment can be achieved according to the width of the cardboard, making it more convenient to use.
[0036] In this embodiment, as Figure 1 , Figure 2 As shown, a sliding block 11 is slidably connected to the fixed rod 2, and the sliding rod 3 is fixedly connected to the sliding block 11 by bolts. The modular assembly facilitates replacement and disassembly.
[0037] In this embodiment, as Figure 1 , Figure 2 As shown, a U-shaped groove 12 is fixedly connected to the limiting plate 4, and the groove 12 is fixed to the sliding rod 3 by bolts. This facilitates the replacement of the limiting plate 4.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
