Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a cardboard conveying device. Background Art

[0002] The cardboard conveying device is mainly used to efficiently and accurately convey cardboard from one position to another. During the cardboard production process, the conveying device can transport the cardboard to the next processing link, such as printing, die-cutting, binding, etc., reducing the time and labor intensity of manual handling and greatly improving the speed of the entire production process.

[0003] In the prior art, only one conveyor belt is provided on the common cardboard conveying device, and the size of the conveyor belt is fixed. Therefore, it cannot stably transport cardboard larger than the size of the conveyor belt. This brings many inconveniences in actual production and limits the flexibility and efficiency of production. When encountering cardboard with a larger size, due to the limitation of the conveyor belt size, part of the cardboard is suspended during the conveying process, and it is easy to shake, shift or even fall. This will not only affect the conveying stability of the cardboard, but may also damage the cardboard and reduce the product quality. In order to improve it, a cardboard conveying device is proposed here. Summary of the Utility Model

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-3 , a cardboard conveying device, including four support frames 1, two rotating shafts 2 are rotatably provided on the four support frames 1, an upper motor 9 connected to one of the rotating shafts 2 is provided on one of the support frames 1, and the two rotating shafts 2 are connected by an upper transmission mechanism. Two rotating rollers 3 are slidably sleeved on each of the two rotating shafts 2. The vertical cross-sectional views of the rotating shafts 2 and the channels corresponding to the rotating rollers 3 on the rotating shafts 2 are designed to be regular hexagons. With this design, no matter how the rotating roller 3 moves and adjusts its position on the rotating shaft 2, the rotation of the rotating shaft 2 can drive the rotation of the rotating roller 3.

[0025] A conveyor belt 4 is provided between every two rotating rollers 3, and a double-headed screw rod 15 is rotatably provided between every two support frames 1. The two double-headed screw rods 15 are connected by a lower transmission mechanism. A lower motor 14 connected to one of the double-headed screw rods 15 is provided on one of the support frames 1. Two nuts 17 are threadedly sleeved on each double-headed screw rod 15 through a limiting mechanism, and each nut 17 is connected to the rotating roller 3 through a connecting mechanism.

[0026] The upper transmission mechanism includes upper pulleys 10 installed on the support frame 1 and connected to the two rotating rollers 3, and the two upper pulleys 10 are connected by an upper belt 11. With the help of the above-mentioned upper pulleys 10 and upper belt 11, the synchronous rotation of the two rotating rollers 3 is achieved. It should be noted that the vertical cross-sectional view of the part where the rotating roller 3 is rotatably connected to the support frame 1 is circular, which will not affect its rotation supported by the support frame 1.

[0027] The lower transmission mechanism includes lower pulleys 12 installed on the support frame 1 and connected to the two double-headed screw rods 15, and the two lower pulleys 12 are connected by a lower belt 13. With the help of the above-mentioned lower pulleys 12 and lower belt 13, the synchronous rotation of the two double-headed screw rods 15 is achieved, and no thread is provided on the outer wall of the part where the double-headed screw rod 15 is rotatably connected to the support frame 1.

[0028] The limiting mechanism includes a limiting rod 16 installed on the support frame 1, and the limiting rod 16 slidably penetrates through the nut 17. With the help of the above-mentioned limiting rod 16, the nut 17 is limited, thus preventing it from rotating together with the double-headed screw 15.

[0029] The connecting mechanism includes an adapter frame 18 installed on the nut 17, and the rotating roller 3 is provided with an adapter groove 19 corresponding to the adapter frame 18. The vertical cross-sectional views of the adapter groove 19 and the part of the adapter frame 18 located in the adapter groove 19 are both L-shaped. This L-shaped design can prevent the rotating roller 3 from disengaging from the adapter frame 18, so it will not move and adjust its position randomly on the rotating shaft 2.

[0030] The edge part of the conveyor belt 4 is provided with a retaining strip 5, the rotating roller 3 is provided with an annular limiting groove, and the conveyor belt 4 is provided with a limiting strip 6 corresponding to the annular limiting groove. The above-mentioned retaining strip 5 can prevent the cardboard transported thereon from falling, and the limiting strip 6 in combination with the annular limiting groove can prevent the conveyor belt 4 from detaching from the rotating roller 3.

[0031] A support plate 7 is installed on every two support frames 1, and the support frame 1 is further provided with a stabilizing rod 8 connected to the support plate 7. The above-mentioned support plate 7 is used to place the cardboard to be transported or the cardboard that has completed transportation, and to collect the cardboard. The stabilizing rod 8 is inclined to effectively support the support plate 7.

[0032] When the present utility model is in use, as Figure 1 shown, the distance between the two conveyor belts 4 can adapt to the placement of tooth plates of a certain size at this time. As the rotating roller 3 is driven to rotate by the rotating shaft 2, the conveyor belt 4 will rotate, so the cardboard on it will move to complete the transportation.

[0033] When the size of the cardboard changes, it is necessary to adjust the distance between the two conveyor belts 4 at this time. The conveyor belt 4 needs to be adjusted by relying on the movement of the rotating roller 3. At this time, it is necessary to start the lower motor 14. The lower motor 14 in combination with the lower pulley 12 and the lower belt 13 can drive the two double-headed screws 15 to rotate. When the double-headed screws 15 rotate, the nut 17 will move, and the nut 17 will drive the rotating roller 3 to move on the rotating shaft 2 through the adapter frame 18. Finally, the distance between the two conveyor belts 4 is adjusted, and it can be adjusted to a size suitable for the cardboard.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
