Abstract
Description
Technical Field
[0001] The present invention belongs to mechanical equipment, and in particular relates to a rail-lifting electric turntable used in application scenarios such as paper mills and logistics conveyor lines. Background Art
[0002] In paper mills and logistics conveyor lines, a turntable that can change the direction of the conveyed object is required when transporting materials. Since the positioning space limits its size, when the length of the conveyed object is greater than the rotation diameter of the conveyor line, if the conveyed object is directly rotated, it will interfere with the conveying equipment connected to the front and rear.
[0003] The existing technology is to lift the conveyed object to a certain height through a pneumatic or hydraulic mechanism and then rotate it. This method requires enlarging the electric turntable base and using a connecting rod mechanism to lift the paper roll to a certain height through four cylinders with a cylinder diameter of 200mm. Due to structural limitations, this method will greatly increase the complexity and uncontrollability of the equipment, and at the same time greatly increase the cost. Summary of the invention
[0004] The present invention aims to provide a new guide rail lifting electric turntable which overcomes the above-mentioned deficiencies of the prior art, reduces the uncontrollability of the prior art, improves the working efficiency of the equipment, and greatly saves costs.
[0005] The technical solution of the present invention:
[0006] The guide rail lifts the electric turntable, the upper part is the conveyor belt, and the lower part is the slewing device. The slewing device includes a motor, a gear, and a slewing support. The conveyor belt includes a driving sprocket, a frame, a material conveyor belt, a guide rail, and a driven sprocket. The conveyor belt and the slewing device are connected to the connecting frame through bolts. The motor drives the slewing support to rotate through the gear, thereby driving the conveyor belt to rotate; the conveyor belt drives the driving sprocket to rotate through the reduction motor, and the driving sprocket drives the material conveyor belt to transport objects. It is characterized in that: the material conveyor belt moves along the shape of the guide rail to transport materials, the guide rail is horizontal in the middle section, and the head and tail ends form a slope of 0.5~3 degrees with the horizontal section, and the height difference between the highest point and the lowest point of the guide rail is 8~30mm.
[0007] The optimal slope between the head and tail ends of the guide rail and the horizontal section is 1 to 2 degrees, and the optimal height difference between the highest point and the lowest point of the guide rail is 10 to 15 mm.
[0008] When the conveyed object is precisely positioned and transported to the center of the turntable, the lower rotating device realizes the steering of the conveyed object. When the diameter of the conveyed object is larger than the diameter of the electric turntable, the rotation of the electric turntable at this time will cause interference with the docking equipment; by designing the front and rear guide rails of the conveyor belt on the guide rail lifting electric turntable to have a slope and a horizontal middle section, the material conveyor belt can automatically climb the slope when carrying the conveyed object on the guide rail. When the conveyed object coincides with the center of the turntable, the conveyed object will be lifted to a certain height relative to the lowest point, so that when the length of the conveyed object is larger than the diameter of the turntable, the conveyed object will not interfere with the turntable docking equipment when the electric turntable rotates.
[0009] The improved effect of the present invention is that the guide rail lifts the electric turntable to change the height of the conveyed object to make it higher than a certain height of the conveyor line to facilitate its turning operation. The material conveyor belt moves along the shape of the guide rail to convey the material. The guide rail is horizontal in the middle section, and the head and tail ends form a slope of 0.5 to 3 degrees with the horizontal section. The height difference between the highest point and the lowest point of the guide rail is 8 to 30 mm. The optimal slope between the head and tail ends of the guide rail and the horizontal section is 1 to 2 degrees, and the optimal height difference between the highest point and the lowest point of the guide rail is 10 to 15 mm. The conveyed object is lifted to a certain height by the conveyor belt climbing and lifting itself, rather than by pneumatic or hydraulic mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The following is a further description of the embodiments in conjunction with the accompanying drawings.
[0017] like Figure 1 , Figure 2 , Figure 4As shown, when the diameter of the conveyed object is larger than the diameter of the electric turntable, the front docking conveyor belt 1 conveys the material to the guide rail lifting electric turntable 2. During the conveying process, the material climbs the guide rail 10 together with the conveyor belt 9 and is lifted to a certain height. The optimal lifting height is 10~15mm. When the material is conveyed to the middle of the guide rail lifting electric turntable 2, the conveyor belt 9 stops conveying. At this time, the rotary device rotates under the drive of the motor. The lowest point of the conveyed material is higher than the conveying surface, so the steering process will not interfere with other equipment. When the steering is in place, the rotary device stops rotating, and the conveyor belt 9 starts working to transport the material to the rear docking conveyor belt 3, thereby realizing the U-turn or steering of the material.
[0018] like Figure 3 As shown, the guide rail lifting electric turntable consists of three parts, and the conveyor belt 4 and the rotating device 5 are connected to the connecting frame 6 by bolts.
[0019] like Figure 4 As shown, the conveyor belt 4 is mainly composed of five parts. The reduction motor drives the driving sprocket 7 to rotate, thereby driving the material conveyor belt 9 to convey. The driven sprocket 11 guides the material conveyor belt 9, and the guide rail 10 carries the load on the material conveyor belt 9. The guide rail 10 is now designed to be horizontal in the middle section, and the front and rear ends are 0.5-3 degrees with the horizontal section, and the optimal is 1-2 degrees; the height difference between the highest point and the lowest point of the guide rail is 8-30mm, and the optimal height difference is 10-15mm. The driving sprocket 7, the material conveyor belt 9, the guide rail 10, the driven sprocket 11, etc. are all installed on the frame 8.
[0020] like Figure 5 As shown, the motor 12 drives the gear 13 to rotate, and the gear 13 meshes with the gear on the slewing support 14 to drive the slewing support 14 to rotate.
[0021] The entire conveying process is detected by photoelectric switches and accurately positioned by encoders to achieve automatic conveying and steering.
