Description

Technical Field

[0001] The utility model relates to a reversing device, and more specifically, to a medicine box reversing device for emulsion explosive production. Background Art

[0002] Emulsion explosives are made by using emulsifiers to evenly disperse droplets of oxidizer salt aqueous solution in an oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres, forming an oil-in-water emulsion explosive.

[0003] During the packing process of emulsion explosives, the directions of some cartons will deviate when they are placed on the roller conveyor for transportation, resulting in the carton opening being unable to cooperate with the tape pasting equipment. Therefore, the carton needs to be rotated and reversed by a reversing device.

[0004] The turntable of existing reversing equipment is equipped with several protruding teeth to increase friction with the bottom of the carton, ensuring smooth rotation. However, these protruding teeth can pierce the carton and cause damage. Furthermore, when the carton contains heavy products, the protruding teeth may pierce the carton and tear it during rotation. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies of the above-mentioned prior art and to provide a medicine box reversing device for emulsion explosive production which has a simple structure and can avoid puncturing the carton.

[0009] In the above-mentioned medicine box reversing device for emulsion explosive production, two lifting cylinders are provided on the frame and the two lifting cylinders are arranged diagonally, and two guide rods are arranged on the bottom diagonals of the lifting plate opposite to each lifting cylinder.

[0010] In the above-mentioned medicine box reversing device for emulsion explosive production, the rotating unit includes a suspension arranged on a lifting plate, a horizontal cylinder is hinged at the bottom of the free end of the suspension through a hinge shaft; a right-angle swing rod is provided between the horizontal cylinder piston rod and the rotating shaft.

[0011] In the above-mentioned medicine box reversing device for emulsion explosive production, the upper end of the baffle is provided with an outwardly curved anti-stab portion.

[0012] In the above-mentioned medicine box reversing device for emulsion explosive production, a gasket made of flexible material is provided on the surface of the rotating disk, and an anti-slip layer is provided on the surface of the gasket.

[0013] After the utility model adopts the above structure, when a carton that needs to be reversed is detected, the rotating disk rises to the same horizontal plane as the upper end of the conveyor roller, and the carton is blocked by the baffle, so that the carton can be accurately aligned and stopped on the rotating disk, and the baffle located in the centrifugal direction during rotation can prevent the carton from moving outward.

[0021] See Figure 1-5 As shown, the present invention provides a carton reversing device for emulsion explosive production, comprising a roller conveyor 1. The roller conveyor 1 is characterized in that a reversing station 2 comprising a plurality of symmetrically arranged short rollers is provided on the roller conveyor 1. A detection sensor 3 for detecting the orientation of the carton is provided on the roller conveyor 1 at the front end of the reversing station 2. The detection sensor can be a single visual sensor or a combination of multiple sensors, such as infrared sensors. This is a technical solution readily apparent to those skilled in the art and will not be further described here.

[0022] A frame 4 is provided below the reversing station 2, on which a lifting and rotating assembly 5 is provided; a rotating disk 6 is provided on the lifting and rotating assembly 5, and support slats 7 are provided around the rotating disk 6 to match the gaps between the rollers of the roller conveyor 1, and a baffle 8 is provided on the free end of the support slat 7 located at the front end of the rotating centrifugal direction.

[0023] When a carton that needs to be reversed is detected, the rotating disk rises to the same level as the upper end of the conveyor roller, and the carton is blocked by the baffle, so that the carton can be accurately aligned and stopped on the rotating disk. The baffle located in the centrifugal direction during rotation can prevent the carton from moving outward. Compared with the existing tooth plate, it can effectively reduce damage to the carton and prevent the tooth plate from tearing the bottom of the carton during rotation when the carton is heavy.

[0024] In this embodiment, preferably, the lifting and rotating assembly 5 includes a lifting cylinder 5a, and a lifting plate 5b is connected to the piston rod of the lifting cylinder 5a; two guide rods 5c are provided at the bottom of the lifting plate 5b, and the lower ends of the guide rods 5c are matched with the frame 4 through the shaft sleeve 5d; a rotating shaft 5e connected to the rotating disk 6 is provided in the center of the lifting plate 5b through the shaft sleeve, and a rotating unit 9 connected to the rotating shaft 5e is provided on the lifting plate 5b.

[0025] Further preferably, the frame 4 is provided with two lifting cylinders 5a, which are arranged diagonally. Two guide rods 5c are provided at diagonal angles at the bottom of the lifting plate 5b, opposite each lifting cylinder 5a. The use of two lifting cylinders for synchronous lifting can prevent the rotary plate from being unable to raise or lower in a timely manner due to a lifting cylinder failure, thereby preventing the normal conveying of cartons. The diagonal arrangement of the two lifting cylinders and the two guide rods improves stability, ensuring stable lifting even if one of the lifting cylinders fails, preventing the lifting plate from becoming unbalanced or tilting.

[0026] In this embodiment, the rotating unit 9 preferably includes a suspension 9a mounted on the lifting plate 5b. A horizontal cylinder 9c is hingedly connected to the bottom of the free end of the suspension 9a via an articulated shaft 9b. A right-angle swing arm 9d is provided between the piston rod of the horizontal cylinder 9c and the rotating shaft 5e. The rotating shaft rotates by extending or retracting the horizontal cylinder piston rod to cooperate with the right-angle swing arm. The installation angle of the right-angle swing arm and the stroke of the horizontal cylinder piston rod can be determined through trial and error based on the actual installation environment. This is common knowledge to those skilled in the art and will not be elaborated here.

[0027] In this embodiment, the upper end of the baffle 8 is provided with an outwardly curved stab-proof portion 10. When a heavy carton collides with the baffle during transportation, it may not stop in time due to inertia and may move onto the baffle. The stab-proof portion can prevent the baffle from puncturing the bottom of the carton when it rises with the rotating disk.

[0028] In this embodiment, the rotating disk 6 is provided with a flexible gasket 11 with an anti-slip layer. This anti-slip layer decelerates the carton, reducing the impact force between the front end of the carton and the baffle, thus preventing damage to the front end. It also increases friction between the carton and the rotating disk, further preventing the carton from moving outward due to centrifugal force as the rotating disk rotates.

[0029] During operation, when the detection sensor detects a carton that needs to be reversed, the piston rod of the lifting cylinder extends to lift the rotary disk to the same level as the upper end of the conveyor roller. The front end of the carton collides with the baffle and stops on the rotary disk. The piston rod of the lifting cylinder continues to extend to lift the selection turntable above the conveyor roller. The piston rod of the horizontal cylinder extends or retracts to drive the selection turntable to rotate 90° to reverse the carton.

[0030] Then the lifting cylinder piston rod is retracted to make the rotating disk drop to the bottom of the conveyor roller. After the bottom of the carton touches the conveyor roller, it continues to be conveyed. The horizontal cylinder piston rod drives the selection turntable to rotate 90° and return to the initial state to wait for the next reversing operation.

[0031] The above embodiments are preferred implementation methods of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. These modifications still fall within the scope of the technical features of the present invention.
