[0041] As described in the background art, when the width of the paper roll is greater than the diameter of the electric turntable, the paper roll interferes with the foundation and peripheral equipment during the rotation of the turntable.

[0042] In order to solve the above problems, the embodiments of the present application provide a lifting and rotating conveying device applied to paper mills, logistics conveying lines and other scenes, such as Figure 1-Figure 2As shown, the lifting and rotating conveying device includes a rotating device 100, a bearing seat 200, a lifting mechanism 300 and a conveyor 400. The bearing seat 200 is arranged on the rotating device 100, and the bearing seat 200 can rotate under the action of the rotating device 100. The lifting mechanism 300 is arranged on the bearing seat 200, and the conveyor 400 is arranged on the lifting mechanism 300. The conveyor 400 can rise upward under the action of the lifting mechanism 300, and the conveyor 400 is used to transport cylindrical materials (including but not limited to paper rolls, cloth rolls and other rolls).

[0043] In the embodiment of the present application, the lifting and rotating conveying device comprises a rotating device 100, a bearing seat 200 disposed on the rotating device 100, a lifting mechanism 300 disposed on the bearing seat 200, and a conveyor 400 disposed on the lifting mechanism 300. The lifting mechanism 300 can lift the conveyor 400 and the paper roll on the conveyor 400 to a certain height (preferably, lift more than 10 mm), and the rotating device 100 can drive the bearing seat 200, the lifting mechanism 300, the conveyor 400 and the paper roll on the conveyor 400 to rotate together. The lifting and rotating conveying device is used to lift the paper roll transported to the conveyor 400 to a certain height and then rotate it, so as to prevent the transported paper roll from interfering with the ground and surrounding equipment.

[0044] In one embodiment, if Figure 2 and Figure 4 As shown, there are at least two lifting mechanisms 300 , and at least two lifting mechanisms 300 are arranged at intervals in the conveying direction of the conveyor 400 .

[0045] A plurality of lifting mechanisms 300 are arranged along the conveying direction of the conveyor 400 , and the plurality of lifting mechanisms 300 are used to jointly support the conveyor 400 , thereby improving the stability of the conveyor 400 .

[0046] Specifically, the lifting mechanism 300 includes but is not limited to a vertically arranged air cylinder, an air tire (air bag), an oil cylinder and an electric cylinder. Since the paper roll has a large load, the lifting mechanism 300 is stable and reliable and can bear a large load. Taking the air cylinder as an example, the cylinder body of the air cylinder is fixed on the bearing seat 200, and the piston rod of the air cylinder is vertically upward and connected to the frame 410 of the conveyor 400.

[0047] In one embodiment, if Figure 2 and Figure 3 As shown, the lifting and rotating conveying device also includes a lifting guide assembly 700, which includes a guide rail arranged on the bearing seat 200 and extending vertically upward, and a slider arranged on the conveyor 400 and slidably connected to the guide rail.

[0048] The lifting guide assembly 700 provides guidance during the process of the lifting mechanism 300 lifting the conveyor 400, thereby improving the stability of the conveyor 400 during the up and down movement.

[0049] In one embodiment, if Figure 1 and Figure 4-Figure 6 As shown, the rotating device 100 includes a base 110, a rotating bearing 120, a rotating motor 130 and a driving gear 140. The rotating bearing 120 includes an inner ring 121 and an outer gear ring 122 that are rotatably connected. The inner ring 121 is fixed on the base 110, and the supporting seat 200 is fixed on the outer gear ring 122; the rotating motor 130 is installed on the base 110, and the driving gear 140 is fixed on the motor shaft of the rotating motor 130 and meshes with the outer gear ring 122.

[0050] In the slewing device 100, the base 110 plays a supporting role, and the slewing bearing 120 is used to realize the rotation connection between the bearing seat 200 and the top of the base 110. The driving gear 140 drives the outer gear ring 122 of the slewing bearing 120 meshing therewith to rotate under the action of the rotating motor 130, thereby driving the bearing seat 200 to rotate, so as to adjust the position of the jacking mechanism 300 and the conveyor 400 arranged on the bearing seat 200. The gear transmission formed between the driving gear 140 and the outer gear ring 122 of the slewing bearing 120 has the characteristics of large bearing capacity, stable transmission and high transmission accuracy, which is conducive to realizing high-precision position adjustment.

[0051] In one embodiment, if Figure 1-Figure 3 , Figure 5 and Figure 7 As shown, the conveyor 400 includes a frame 410 arranged on the top of the supporting base 200, a conveying chain plate 420 installed on the frame 410, and a driving mechanism 430 and a tensioning mechanism 440 installed at opposite ends of the frame 410. The driving mechanism 430 is used to drive the conveying chain plate 420 to operate, and the tensioning mechanism 440 is used to adjust the tightness of the conveying chain plate 420.

[0052] It can be understood that the conveyor 400 in this embodiment is a chain conveyor. Of course, in other embodiments, the conveyor 400 can also be a belt conveyor, a roller conveyor, etc., as long as it can convey horizontal (lying) paper rolls.

[0053] Furthermore, if Figure 2-Figure 5 As shown, the lower ends of the frames 410 corresponding to the head and tail of the conveyor 400 are respectively provided with load-bearing wheel assemblies 600 for assisting in supporting the weight of the paper roll when it enters and exits the conveyor 400. Since there is a gap between the inner and outer rings of the slewing bearing 120, when the paper roll enters and exits the conveyor 400, the head or tail of the conveyor 400 will sink and tilt, and the load-bearing wheel assemblies 600 are used to ensure that the materials are smoothly transported when entering and exiting the conveyor 400.

[0054] Specifically, the load-bearing wheel assembly 600 includes a track 610 for installation on the ground, two brackets (not shown in the figure) respectively installed at opposite ends of the frame 410 of the conveyor 400 and extending downward, and two rollers 620 respectively installed at the lower ends of the two brackets, and the rollers 620 can contact the track 610.

[0055] In a specific embodiment, Figure 1 , Figure 3-Figure 5 As shown, the frame 410 is provided with semicircular support plates 500 on opposite sides of the conveying chain plate 420. The support plates 500 can cover the structure below the support plates 500, making the entire lifting and rotating conveying device more beautiful, and also facilitating the subsequent installation of sensors for detecting the presence of paper rolls on the support plates 500.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
