Description

Technical Field

[0001] This utility model relates to the field of stacking equipment technology, specifically to an automatic cardboard stacking and lifting device. Background Technology

[0002] After the cardboard is produced, the quantity usually needs to be calculated according to the customer's requirements for unified packaging. Before packaging, the cardboard needs to be neatly stacked to facilitate packaging.

[0003] To facilitate cardboard stacking, existing technologies have made numerous improvements to automatic cardboard stacking and lifting devices. For example, patent publication number CN214610682U discloses an automatic cardboard stacking and lifting device, comprising: a support frame, with an operating platform, rollers, a fixed base, and a conveyor belt arranged sequentially from left to right on the inner side of the support frame; a mounting frame disposed on one side of the support frame; conveyor wheels mounted inside the mounting frame; a collection box disposed below one side of the support frame; a stacking plate disposed inside the collection box; and a second hydraulic rod disposed at the bottom of the collection box. This automatic cardboard stacking and lifting device uses rollers to drive a rubber sleeve to rotate, which conveys the cardboard. The rubber sleeve has raised dots on its surface to increase friction with the cardboard. The conveyor wheels output the cut cardboard, which falls into the collection box for storage, thus facilitating cardboard stacking and subsequent processing by operators.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the aforementioned comparative documents, cardboard is conveyed via a conveyor belt and then stacked on a stacking pallet. However, in reality, when stacking finished cardboard, its edges need to be aligned. If the edges are not aligned during stacking, the cardboard stack will become skewed or even tip over. Furthermore, when conveying cardboard of different sizes to the stacking pallet in the aforementioned comparative documents, manual alignment is required, which reduces the efficiency of cardboard stacking. Therefore, there is an urgent need in the art to improve the automatic cardboard stacking and lifting device to overcome the shortcomings of the prior art. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] Example 1

[0033] Please see Figures 1-10 An automatic cardboard stacking and lifting device includes a support base 1 installed at the tail end of a conveying device 2. A support seat 3 is provided on the upper part of the support base 1. Several vertical columns 4 are fixedly installed on the side of the support seat 3. A stacking plate 5 adapted to the conveying device 2 is provided above the support seat 3. A first drive unit 6 for driving the stacking plate 5 to move up and down is provided on the upper part of the vertical columns 4. Several symmetrical sliding plates 7 are slidably connected to the upper part of the conveying device 2. An alignment plate 8 adapted to the stacking plate 5 is provided on the upper part of the sliding plates 7. A second drive unit 9 for simultaneously driving several sliding plates 7 to move towards or away from each other is provided on the upper part of the support seat 3. A third drive unit 10 for moving the support seat 3 is provided on one side of the support base 1.

[0034] Specifically, when stacking the produced cardboard, the support base 1 is fixedly installed at the end of the conveying device 2. The first drive unit 6 drives the stacking plate 5 to move upward to a position that matches the conveying device 2. The conveying device 2 conveys the cardboard, which is then transported to the stacking plate 5. The size of the stacking plate 5 is equal to the size of the cardboard. Simultaneously, the stacking plate 5 moves downward intermittently via the first drive unit 6. After a certain number of cardboards are transported to the stacking plate 5, the second drive unit 9 is activated. The second drive unit 9 drives several sliding plates 7 to move towards each other simultaneously. The sliding plates 7 drive several alignment plates 8 to move towards each other. The alignment plates 8 align the cardboards on the stacking plate 5, improving the efficiency of cardboard stacking. It is worth noting that one of the alignment plates 8 is located below the conveying device 2 and its length is shorter than the other alignment plates 8, so it does not obstruct the conveying device 2 from conveying the cardboard.

[0035] As a technical optimization of this utility model, the first drive unit 6 includes a first drive motor 11 fixedly installed on the upper part of the vertical column 4. Each vertical column 4 has a connecting plate 12 on its opposite side. A connecting seat 13 for supporting the stacking plate 5 is fixedly connected between the ends of several connecting plates 12 away from the vertical column 4. A first sliding block 14 is fixedly installed on one end of the connecting plate 12. A first sliding groove 15 adapted to the first sliding block 14 is opened on the side of the vertical column 4. A first adjusting screw 16 is rotatably connected in the first sliding groove 15, with one end fixedly installed to the output end of the first drive motor 11. The first adjusting screw 16 passes through the first sliding block 14 and is threadedly connected to it. A symmetrical opening groove 34 is opened on the upper part of the stacking plate 5.

[0036] Specifically, several synchronous first drive motors 11 are started. The output end of the first drive motor 11 drives the first adjusting screw 16 to rotate. When the first adjusting screw 16 rotates, it drives the first sliding block 14 to slide in the first sliding groove 15. The first sliding block 14 drives the connecting plate 12 to move. Several connecting plates 12 drive the connecting seat 13 to move, thereby moving the stacking plate 5 up and down. After the cardboard is stacked, the cardboard stack on the stacking plate 5 is transferred by a forklift or other transfer device in cooperation with the opening groove 34.

[0037] As a technical optimization of this utility model, the second drive unit 9 includes a second drive motor 17 fixedly installed on the upper part of the support base 3. A rotating ring 18 located below several sliding plates 7 is rotatably connected inside the support base 1. Several gears 19 are rotatably connected inside the support base 3. The gears 19 mesh with both the sliding plates 7 and the rotating ring 18. The second drive motor 17 drives one of the gears 19 to rotate.

[0038] Specifically, the second drive motor 17 is started, and the output end of the second drive motor 17 drives one of the gears 19 to rotate. The gear 19 drives the rotating ring 18 to rotate, and the rotating ring 18 drives several gears 19 to rotate simultaneously. The several gears 19 simultaneously drive the sliding plate 7 to move, thereby achieving the effect of several sliding plates 7 moving towards or away from each other at the same time.

[0039] As a technical optimization of this utility model, the third drive unit 10 includes a third drive motor 20 fixedly installed on one side of the support base 1, a second sliding block 21 fixedly installed on the lower part of the support base 3, a second sliding groove 22 adapted to the second sliding block 21 opened on the upper part of the support base 1, a second adjusting screw 23 rotatably connected in the second sliding groove 22 with one end fixedly installed to the output end of the third drive motor 20, the second adjusting screw 23 passing through the second sliding block 21 and threadedly connected to it, a polygonal limiting block 24 fixedly connected on the upper part of the connecting seat 13, and a limiting groove 25 adapted to the limiting block 24 opened on the lower part of the stacking plate 5.

[0040] Specifically, when stacking cardboard of different sizes, the position of the support seat 3 on the support base 1 needs to be adjusted. At this time, the third drive motor 20 is started. The output end of the third drive motor 20 drives the second adjusting screw 23 to rotate. When the second adjusting screw 23 rotates, it drives the second sliding block 21 to move in the second sliding groove 22. The second sliding block 21 drives the support seat 3 to move, thereby adjusting the position of the support seat 3 on the support base 1, thus achieving the effect of stacking cardboard of different sizes. At the same time, if it is necessary to stack cardboard of different sizes, the stacking plate 5 with the appropriate size for the cardboard is inserted into the side of the upper limit block 24 of the connecting seat 13 through the limiting groove 25 at its lower part, which facilitates the replacement and installation of the stacking plate 5.

[0041] Example 2

[0043] In this embodiment, when stacking rectangular cardboard, the position of the alignment plate 8 on the sliding plate 7 needs to be adjusted. By rotating the adjusting bolt 28, the third sliding block 26 is driven to move within the third sliding groove 27, adjusting the position of the alignment plate 8 on each sliding plate 7. When several sliding plates 7 move, several alignment plates 8 can simultaneously press against the side of the cardboard, achieving the effect of aligning and stacking rectangular cardboard. Then, the limiting nut 29 is tightened to limit and fix the position of the adjusting bolt 28, improving the applicability of stacking cardboard.

[0044] Example 3

[0045] Please see Figure 7 This embodiment includes all the above embodiments, and further includes: an L-shaped plug block 30 fixedly connected to the lower end of the alignment plate 8; a plug groove 31 adapted to the plug block 30 is provided through the opposite side of the third sliding block 26; a limiting rod 32 with a T-shaped cross section is provided through the upper part of the third sliding block 26, and a spring 33 is fixedly installed between the limiting rod 32 and the upper part of the third sliding block 26.

[0046] In this embodiment, the specific implementation method is as follows: When the alignment plate 8 is installed, the limiting rod 32 is pulled away from the third sliding block 26. At this time, the spring 33 is stretched and inserted into the insertion slot 31 through the insertion block 30. After the insertion block 30 is aligned with the third sliding block 26, the limiting rod 32 is released. At this time, the contraction force of the spring 33 drives one end of the limiting rod 32 to be inserted into one side of the insertion block 30, which facilitates the installation or replacement of the alignment plate 8. It can stack cardboard conveyed by the conveying device 2 at different heights, thereby improving the applicability of the overall device.
