Description

Technical Field

[0001] This utility model belongs to the technical field of packaging, and specifically relates to a horizontal wrapping machine box-turning mechanism. Background Technology

[0002] Currently, the existing turning mechanism is a right-angle turning conveyor. This conveyor can turn the material at a right angle of 90° during the material conveying process, thereby changing the material conveying direction. Because the material conveying speed is required to be fast, and the contact area between the material and the conveyor belt is narrow (the material is generally narrow and long, and the contact area between the bottom of the material and the conveyor belt is small), the material will tilt and skew when turning, resulting in a high failure rate. Utility Model Content

[0003] This utility model proposes a horizontal wrapping machine box turning mechanism, which solves the problems of box tipping and lateral tilting that easily occur when materials are transported through right-angle turns.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A horizontal wrapping machine's rotating box mechanism includes an upper feeding platform and a lower discharging platform. The upper feeding platform and the lower discharging platform are arranged parallel to each other at a 90° angle. A rectangular opening is provided at the top of the upper feeding platform. Material-supporting flaps are rotatably connected to the two parallel sides of the rectangular opening. The two material-supporting flaps are connected by a tension spring. A push plate is provided directly above the rectangular opening, which is used to push the material downward from the rectangular opening. A rotating base plate is rotatably connected to the top of the lower discharging platform. The rotating base plate corresponds to the rectangular opening and is used to receive the material falling from the rectangular opening and rotate the material 90°. Three U-shaped rotating baffles are installed on the top of the rotating base plate. The area enclosed by the three rotating baffles is used to accommodate the material falling from the rectangular opening and to limit the material.

[0006] Through the above technical solution, this utility model enables the layered transportation of materials that require right-angle turns, thereby achieving 90° turning operations. Moreover, to address the issue of small contact area between materials and the conveyor belt, a rectangular opening is designed. This rectangular opening can accommodate multiple materials at once, and its width matches the number of materials. The materials fall from the rectangular opening onto the rotating base plate for subsequent 90° turning. To prevent materials from tipping over or tilting, three U-shaped rotating baffles are installed on the rotating base plate to limit the material's movement after it falls, reducing the failure rate of materials after the right-angle turn.

[0007] Optionally, three feed baffles are installed around the rectangular opening. The three feed baffles are distributed in a U-shape and are used to limit the material entering the feed platform.

[0008] Through the above technical solution, the three feeding baffles can limit the material that is about to turn when it enters the rectangular opening, so as to prevent the material from tipping over or tilting to the side, and also facilitate the subsequent material to be neatly pushed down onto the rotating base plate.

[0009] Optionally, the two material-supporting flaps are located on both sides of the rectangular opening, which are arranged in parallel and spaced apart. The tension spring is located at the bottom of the material-supporting flaps, and the tension spring keeps the two material-supporting flaps in a horizontal state through elastic force.

[0010] Through the above technical solution, the tension spring can keep the two material support flaps in a horizontal state when the material at the rectangular opening is not pushed down, so that the two material support flaps provide stable support for the material. When the push plate pushes the material down, it needs to overcome the elastic force of the tension spring. After the push plate resets, the material support flaps also automatically reset under the elastic force of the tension spring.

[0011] Optionally, an mounting plate is installed at the same end of the two material-supporting flaps, the mounting plate has mounting holes, and a tension spring is connected between the two mounting holes at the same end of the two material-supporting flaps.

[0012] Optionally, a push cylinder is installed on one side of the feeding platform. The piston rod of the push cylinder is fixedly connected to a connecting plate, and the end of the connecting plate is fixedly connected to a push plate. The push plate is arranged parallel to the feeding platform at intervals, and the push plate is located directly above the rectangular opening.

[0013] Optionally, a rotary servo motor is installed at the bottom of the discharge platform, and a rotary shaft is installed at the end of the output shaft of the rotary servo motor. The upper end of the rotary shaft passes vertically upward through the discharge platform and is fixedly connected to the bottom of the rotary base plate.

[0014] Optionally, a slide rail and a feeding cylinder are fixedly connected to the top of the discharge platform. The slide rail and the feeding cylinder are arranged parallel to each other and spaced apart. A feeding push plate is fixedly connected to the end of the piston rod of the feeding cylinder. The feeding push plate is at a 90° angle to the end of the piston rod of the feeding cylinder. A slider is fixedly connected to the bottom of the feeding push plate. The slider is slidably connected to the slide rail.

[0015] Through the above technical solution, the feeding cylinder drives the feeding pusher plate to move. During the movement, the feeding pusher plate comes into contact with the material located in the area surrounded by three rotating baffles, and shapes and aligns the material so that the material remains in a regular state.

[0016] Optionally, the upper feeding platform and the lower discharging platform are connected by several support pillars.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This invention designs a rotating box mechanism. The mechanism first pushes the stacked boxes downwards into the hopper, then rotates the material 90° using a rotating mechanism, and finally pushes it into the feeding channel. The material first accumulates on the second-layer support plate, then a double-rod cylinder presses the material down into the first-layer hopper. A servo motor then drives the rotating hopper to rotate 90° clockwise, and finally a single-rod cylinder pushes the material into the feeding channel. This mechanism allows the material to rotate during transport, thus preventing box tipping and lateral tilting when changing transport direction, reducing the failure rate, and improving the stability of right-angle turns while maintaining transport speed.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This application discloses a horizontal wrapping machine box-turning mechanism.

[0030] Example

[0031] according to Figures 1 to 7 As shown, a horizontal wrapping machine's box-turning mechanism includes an upper feeding platform 1 and a lower discharging platform 2. The upper feeding platform 1 and the lower discharging platform 2 are distributed at intervals. The upper feeding platform 1 is located above the lower discharging platform 2. The upper feeding platform 1 and the lower discharging platform 2 are connected by several support columns 11. The upper feeding platform 1 and the lower discharging platform 2 are distributed in an L-shape.

[0032] A pushing mechanism is installed on the top of the feeding platform 1. The pushing mechanism includes a pushing cylinder 3, a pushing plate 4, a feeding baffle 6, and a material-supporting flap 7. A rectangular opening 10 is provided on the top of the feeding platform 1. Three feeding baffles 6 are installed around the rectangular opening 10. The three feeding baffles 6 are distributed in a U-shape and are used to limit the material entering the feeding platform 1. The feeding baffles 6 are L-shaped. The bottom of the feeding baffles 6 is detachably connected to the feeding platform 1 by bolts. Two parallel material-supporting flaps 7 are rotatably connected on both sides of the rectangular opening 10. An mounting plate 8 is installed on the same end of the two material-supporting flaps 7. The mounting plate 8 has mounting holes 9. A tension spring is connected between the two mounting holes 9 on the same end of the two material-supporting flaps 7. The tension spring is located at the bottom of the material-supporting flap 7. The tension spring keeps the two material-supporting flaps 7 in a horizontal state through elastic force. The rectangular opening 10 and the material-supporting flaps 7 cooperate to receive materials that need to turn at right angles. The rectangular opening 10 without the material support flap has vertical plates 21 installed on both sides. The two vertical plates 21 are arranged in parallel and spaced apart. When the push plate pushes the material down, the two vertical plates 21 can provide guidance for the material.

[0033] A downward-pushing cylinder 3 is installed on one side of the upper feeding platform 1. The piston rod of the downward-pushing cylinder 3 is vertically upward, and a connecting plate 5 is fixedly connected to the piston rod of the downward-pushing cylinder 3. A downward-pushing plate 4 is fixedly connected to the end of the connecting plate 5. The downward-pushing plate 4 is arranged parallel to the upper feeding platform 1 at intervals. The downward-pushing plate 4 is located directly above the rectangular opening 10. The downward-pushing cylinder 3 drives the downward-pushing plate 4 to move up and down through the extension and retraction of the piston rod, thereby pushing the material entering the rectangular opening 10 downward. The force of the downward-pushing plate 4 pushing the material downward pushes the two material-supporting flaps 7 to rotate downward. The material falls downward to the top of the lower discharging platform 2. After the material falls, the piston rod of the cylinder drives the downward-pushing plate 4 to reset. The two material-supporting flaps 7 reset to a horizontal state under the elastic action of the tension spring.

[0034] A rotating mechanism is installed on the top of the discharge platform 2. The rotating mechanism includes a rotating base plate 13, a rotating baffle 14, and a rotating servo motor 12. The rotating servo motor 12 is installed at the bottom of the discharge platform 2. The output shaft of the rotating servo motor 12 is vertically upward. A rotating shaft 15 is installed at the end of the output shaft of the rotating servo motor 12. The lower end of the rotating shaft 15 is fixedly connected to the end of the output shaft of the rotating servo motor 12. The upper end of the rotating shaft 15 is vertically upward and passes through the discharge platform 2. The upper end of the rotating shaft 15 is fixedly connected to the bottom of the rotating base plate 13. Machine 12 drives the rotating shaft 15 to rotate, thereby driving the rotating base plate 13 to rotate. The rotating servo motor 12 drives the rotating base plate 13 to rotate 90°. Three rotating baffles 14 are installed on the top of the rotating base plate 13. The three rotating baffles 14 are distributed in a U-shape and are located directly below the rectangular opening 10. The area enclosed by the three rotating baffles 14 matches the size of the rectangular opening 10. The three rotating baffles 14 are used to limit the material falling from the feeding platform 1 to prevent the material from tipping over or tilting to the side.

[0035] A feeding mechanism is installed on the top of the discharge platform 2. The feeding mechanism includes a slide rail 17, a feeding cylinder 16, a feeding bottom plate baffle 20, and a feeding push plate 19. The slide rail 17 and the feeding cylinder 16 are both fixedly connected to the top of the discharge platform 2. The slide rail 17 and the feeding cylinder 16 are arranged parallel to each other and spaced apart. The end of the piston rod of the feeding cylinder 16 is fixedly connected to the feeding push plate 19. The feeding push plate 19 is at a 90° angle to the end of the piston rod of the feeding cylinder 16. When the rotating bottom plate 13 rotates to be parallel to the discharge platform 2 and... When the upper feeding platform 1 is at a 90° angle, the rotating base plate 13 is parallel to the slide rail 17 and the feeding push plate 19 corresponds to the opening of the three rotating baffles 14. The bottom of the feeding push plate 19 is fixedly connected to the slider 18, which is slidably connected to the slide rail 17. The feeding cylinder 16 drives the feeding push plate 19 to move. During the movement, the feeding push plate 19 pushes the material so that the material is completely within the area enclosed by the three rotating baffles 14, thereby limiting and shaping the material and preventing the material from tipping over or tilting to the side.

[0036] The top of the discharge platform 2 is fixedly connected to two parallel, spaced-apart feed bottom plate baffles 20. The distance between the two feed bottom plate baffles 20 matches the length of the material within the area enclosed by three rotating baffles 14. The feed push plate 19 is located at the ends of the two feed bottom plate baffles 20. After the material makes a right-angle turn, the feed bottom plate baffles 20 comb the material and guide it, facilitating connection between the material and the feed channel of the subsequent connected equipment.

[0037] Working principle:

[0038] The materials during transportation are rectangular and placed vertically. As a result, the contact area between the rectangular block and the conveyor belt is small, and the transportation process is unstable when turning. When the conveyed materials enter the rectangular opening 10 at the top of the feeding platform 1 (the amount of material matches the width of the rectangular opening 10), the materials are supported by two material support flaps 7.

[0039] The rotary servo motor 12 drives the rotating shaft to rotate, which in turn drives the rotating base plate 13 to rotate. The rotating base plate 13 rotates to the area directly below the rectangular opening 10. At this time, the area enclosed by the three feeding baffles 6 corresponds to the area enclosed by the three rotating baffles 14. The downward pushing cylinder 3 is activated, and the piston rod of the downward pushing cylinder 3 drives the downward pushing plate 4 to move downward. The downward pushing plate 4 contacts the material at the rectangular opening 10 and applies downward pressure. The pressure applied by the downward pushing plate 4 overcomes the elastic force of the tension spring, and the material pushes the material-supporting flip plate 7 to rotate downward. The material falls from the rectangular opening 10 to the top of the rotating base plate 13, and falls exactly into the area enclosed by the three rotating baffles 14. At this time, the rotary servo motor 12 drives the rotating shaft to rotate in the opposite direction, and the rotating shaft drives the rotating base plate 13 to rotate in the opposite direction until the rotating base plate 13 rotates to be parallel to the discharge lower platform 2 and at a 90° angle to the feeding upper platform 1. At this time, the opening of the area enclosed by the three rotating baffles 14 faces the feeding push plate 19.

[0040] The feeding cylinder 16 is activated, and through its piston rod, it drives the feeding push plate 19 to move towards the rotating base plate 13. During this movement, the feeding push plate 19 contacts the material and pushes it into the area enclosed by the three rotating baffles 14. This allows the feeding push plate 19 to shape the material within the area enclosed by the three rotating baffles 14, ensuring the material remains regular and preventing tipping or lateral tilting. Finally, the material that has completed the right-angle turn is transported away by other mechanisms, and the cycle repeats. The rotating box mechanism in this invention is only responsible for making 90° turns of the material without causing tipping or lateral tilting.
