Description

Technical Field

[0001] This utility model relates to the field of tobacco frame conveying technology, and in particular to an automated intelligent production line for tobacco leaf purchasing. Background Technology

[0002] In the tobacco purchasing line, after the tobacco crates filled with tobacco leaves are transported to the storage bin and emptied, the traditional method is to manually remove the empty crates from the storage bin and place them on a transfer vehicle. Once the transfer vehicle is full of empty crates, they are then transported to the tobacco purchasing area to continue storing the purchased tobacco leaves. Because the storage bin opening is high, manually removing empty crates is inconvenient and carries certain risks. The high-intensity labor quickly fatigues workers, slows down the transport pace, and hinders the improvement of purchasing efficiency. Multiple people passing the crates can lead to crates being thrown from a height, causing damage. Hiring a large number of people for handling the crates results in high labor costs.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention; that is, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Specific embodiments of the automated intelligent production line for tobacco leaf purchasing provided by this utility model:

[0025] Please see Figure 1-6 An automated intelligent production line for tobacco leaf purchasing includes a lifting frame 1, a U-shaped tobacco receiving frame 2, a conveyor 3, and a diagonal support frame 4.

[0026] The lifting frame 1 moves up and down on one side of the storage box 16 where tobacco leaves are stored. Specifically, the lifting frame 1 is provided with a base 5 below it, which is located on one side of the storage box 16. The base 5 is provided with a vertical track 6 on its upper side, and the lifting frame 1 is provided with a slider 7 that slides vertically along the track 6.

[0027] A lead screw 8 and a first motor 9 for driving the lead screw 8 to rotate are mounted on the base 5. The base 5 includes a base plate and a reinforcing tube connected to the lower edge of the base plate. The lead screw 8 is vertically positioned on the upper side of the base plate, and the first motor 9 is mounted on the lower side of the base plate. The output shaft of the first motor 9 is connected to the lead screw 8. A threaded cylinder 10 is provided on the lifting frame 1. The lead screw 8 passes through the threaded cylinder 10 and is threadedly connected to the threaded cylinder 10.

[0028] There are two tracks 6, and the lead screw 8 is located between the two tracks 6. In this embodiment, an aluminum alloy profile is provided on the upper side of the base 5, the track 6 is located on one side of the aluminum alloy profile, and a plate-shaped or tubular reinforcing body is provided on the other side of the aluminum alloy profile. The lower end of the reinforcing body is connected to the base 5.

[0029] The lifting frame 1 has an inverted L-shaped plate structure. The vertical section of the lifting frame 1 is provided with two sliders 7 and a threaded cylinder 10 as described above. The two sliders 7 are located on both sides of the threaded cylinder 10.

[0030] Through the above structure, the first motor 9 drives the lead screw 8 to rotate, causing the threaded cylinder 10 to rise and fall, and causing the lifting frame 1 and the slider 7 to rise and fall vertically and stably along the track 6.

[0031] On the other side of the storage bin 16, a conveying device and a transfer device are provided. The conveying device transports the tobacco frames filled with tobacco leaves to the side of the storage bin 16. The transfer device lifts, moves, and flips the tobacco frames on the conveying device, pouring the tobacco leaves in the frames into the storage bin 16. After the tobacco leaves are poured out, the frames are flipped to an upright position with the opening facing upwards.

[0032] The U-shaped smoke receiving frame 2 is horizontally rotatably mounted on the upper side of the lifting frame 1. The smoke receiving frame 2 is connected to the upper side of the horizontal section of the lifting frame 1 through a rotary support, so as to achieve stable horizontal rotation of the smoke receiving frame 2.

[0033] An external gear ring 11 is connected to the lower side of the smoke receiving frame 2. The rotation center of the external gear ring 11 is located on the same vertical line as the rotation center of the aforementioned rotary support. A gear 12 and a second motor 13 that drives the gear 12 are installed on the horizontal section of the lifting frame 1. The gear 12 meshes with the external gear ring 11.

[0034] The second motor 13 drives the gear 12 to rotate in both directions, causing the outer gear ring 11 and the smoke receiving frame 2 to reciprocate. In some other embodiments, a rotary cylinder can be used instead of the combination structure of the outer gear ring 11, gear 12, and second motor 13. The rotary cylinder can realize the reciprocating rotation of the smoke receiving frame 2, and the rotation angle can be accurately controlled.

[0035] In this embodiment, both the first motor 9 and the second motor 13 are servo motors to ensure the accuracy of the positions of the lifting frame 1 and the smoke receiving frame 2, which facilitates intelligent control. In some embodiments, position detection sensors are set to further improve the accuracy of the movements of the lifting frame 1 and the smoke receiving frame 2.

[0036] Conveyor 3 is located on one side of lifting frame 1 and is used to transport empty smoke frames 15. In this embodiment, roller conveyor 3 is used. Inclined support frame 4 is connected to the upstream end of conveyor 3. Inclined support frame 4 is inclined upwards away from conveyor 3, and vertically aligns with the U-shaped opening of smoke receiving frame 2, allowing the empty smoke frame 15 to slide down to the upper side of conveyor 3. In this embodiment, the smoke receiving frame 2 can be rotated 90 degrees to vertically align with both the inclined support frame 4 and the storage box 16.

[0037] In this embodiment, the inclined support frame 4 includes an inclined plate, one end of which is connected to the fixed part of the conveyor 3, and the other end is provided with a support leg on its lower side. After the empty smoke frame 15 falls on the upper side of the inclined plate, it slides down to the upstream end of the conveyor 3. In some other embodiments, several parallel rollers are provided on the upper side of the inclined plate, which allows the empty smoke frame 15 to slide down to the conveyor 3 even at a smaller inclination angle.

[0038] The width of the inclined support frame 4 is less than the width of the inner side of the opening of the smoke receiving frame 2. After the smoke receiving frame 2 descends with the lifting frame 1, the two ends of the opening of the smoke receiving frame 2 are located on both sides of the inclined support frame 4. The inclined support frame 4 replaces the smoke receiving frame 2 to support the empty smoke frame 15. The width of the conveyor 3 is greater than the length of the empty smoke frame 15.

[0039] To ensure the stability of the empty smoke frame 15 and prevent it from slipping, support plates 14 are provided on the outer sides of both ends of the opening of the smoke receiving frame 2 to support the empty smoke frame 15. When supporting the empty smoke frame 15, both ends of the smoke receiving frame 2 and the support plates 14 are supported on the underside of the empty smoke frame 15. The end of the support plate 14, that is, the end of the support plate 14 away from the smoke receiving frame 2, is bent upward to limit the empty smoke frame 15 and prevent it from falling off.

[0040] Empty smoke frame 15 transfer process:

[0041] After the lifting frame 1 rises to the high position, the smoke receiving frame 2 rotates, and the opening of the smoke receiving frame 2 rotates to the upper side of the storage box 16 and the lower side of the empty smoke frame 15.

[0042] The transfer device will release the empty smoke frame 15, which will fall onto the upper side of the opening end of the smoke receiving frame 2.

[0043] The smoke receiving frame 2 is rotated 90 degrees in the opposite direction, and the open end is vertically aligned with the diagonal brace 4;

[0044] The lifting frame 1 descends until it reaches the opening of the smoke receiving frame 2, with both ends located on either side of the inclined support frame 4.

[0045] The inclined support frame 4 supports the empty tobacco frame 15 at an angle. The empty tobacco frame 15 slides down to the conveyor 3 and is transported by the conveyor 3. Several conveyors 3 can be set up to transport the empty tobacco frame 15 to the tobacco leaf collection point.

[0046] The lifting frame 1 rises and connects to the empty smoke frame 15 again, and this process is repeated to achieve the transfer and delivery of the empty smoke frame 15.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
