Description

Technical Field

[0001] This invention relates to tobacco curing, and particularly to a highly efficient automatic tobacco feeding device for tobacco curing barns. Background Technology

[0002] Tobacco curing barns typically have at least three floors. Manually loading tobacco onto the third floor or higher requires climbing equipment, and this method is inefficient, time-consuming, and labor-intensive. Existing technologies include automatic tobacco loading devices for curing barns, such as the patent titled "A Tobacco Leaf Lifting Device for Curing Barns" (publication number CN 215556750 U). This device uses a conveyor belt to transport tobacco rods from lower support rods to higher support rods, where workers on a platform remove the rods from hooks for loading. This only achieves semi-automatic loading on the upper floors of the curing barn, requiring manual intervention, and the loading efficiency remains relatively low. Another patent, titled "Tobacco Clamping Device for Curing Barns" (publication number CN105645036A), has a highly complex structure, high cost, and poor practicality. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a high-efficiency automatic tobacco feeding device for tobacco curing barns, which solves the technical problems of low automation, complex structure and low tobacco feeding efficiency of existing tobacco curing barn tobacco feeding devices.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A high-efficiency automatic tobacco feeding device for a tobacco curing barn includes a base and a tobacco weaving positioning detection device. The base is equipped with a traveling mechanism, and a support and a support fixed-angle reciprocating rotation control device are horizontally rotatable on the base. A tobacco weaving conveyor belt is mounted on the support and is in an up-and-down state. Multiple tobacco weaving holding devices are spaced apart along the length of the tobacco weaving conveyor belt. The tobacco weaving positioning detection device is connected to the support fixed-angle reciprocating rotation control device and the tobacco weaving holding devices.

[0006] Furthermore, the cigarette holding device includes a cigarette conveyor belt fixed angle retraction control device and a cigarette lifting structure, wherein the cigarette lifting structure is vertically arranged on the surface of the cigarette conveyor belt.

[0007] Furthermore, the cigarette-making lifting structure consists of multiple steel needles arranged along the width direction of the cigarette-making conveyor belt.

One end of a round rod is located in the round hole and the other end is located in the plum blossom hole or the square hole. The other end of the round rod is coaxially formed into a square head near its end. The square head is adapted to the plum blossom hole or the square hole. The round rod is provided with a cigarette lifting structure. The upper end of the support is provided with a square head separation hole driving mechanism.

[0009] Furthermore, the square-headed hole-driving mechanism is a wedge-shaped block, and the inclined surface of the wedge-shaped block faces the round rod.

[0010] Furthermore, the square-headed hole-driving mechanism consists of two magnets, one of which is mounted on a round rod and the other on the upper end of a bracket.

[0011] Furthermore, a square-head inlet drive mechanism is provided on the lower end of the bracket.

[0012] Furthermore, the square-head inlet drive mechanism is a second wedge block, and the inclined surface of the second wedge block faces the round rod.

[0013] Furthermore, the round rod transitions to the conical surface between the round rod and the square head.

[0014] Furthermore, the walking mechanism is controlled by a fixed-distance stopping control system.

[0015] The beneficial effects of this invention are:

[0016] The efficient automatic tobacco feeding device for the tobacco curing barn of the present invention, through a walking mechanism, moves straight to directly below the tobacco feeding position, starts the tobacco feeding device, the support fixed angle reciprocating rotation control device controls the rotation of the support, and the tobacco weaving holding device holds the tobacco weaving, the tobacco weaving conveyor belt conveys the tobacco weaving to above the tobacco feeding position (due to the rotation of the support, the tobacco weaving is tilted relative to the tobacco weaving rack of the tobacco curing barn), the tobacco weaving position detection device detects that the tobacco weaving has reached a certain position above the tobacco feeding position, the support fixed angle reciprocating rotation control device controls the support to return to the upright position, the tobacco weaving holding device puts down the tobacco weaving, and the two ends of the tobacco weaving are neatly overlapped on the tobacco weaving rack of the tobacco curing barn.

[0017] This tobacco feeding device achieves fully automatic tobacco feeding. The tobacco feeding conveyor belt continuously transports the tobacco to the tobacco feeding rack in the tobacco curing room, achieving efficient tobacco feeding. It has a simple structure and low cost.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0029] like Figure 1-7As shown, the efficient automatic tobacco feeding device for a tobacco curing barn includes a base 1 and a tobacco weaving positioning detection device. The tobacco weaving positioning detection device can be an infrared sensor installed inside the tobacco curing barn. A traveling mechanism is located under the base 1. The traveling mechanism is a conventional technology in the mechanical field and will not be described in detail here. The traveling mechanism is controlled by a fixed-distance stopping control system. That is, after tobacco feeding at the previous position is completed, the fixed-distance stopping control system controls the traveling mechanism to move to the next tobacco feeding position. The distance between the previous and next tobacco feeding positions is consistent with the spacing between two adjacent tobacco weaving racks on the existing tobacco curing barn. A support 2 and a fixed-angle reciprocating rotation control device are horizontally rotatable on the base 1. The support 2 is Y-shaped, and its lower end 11 is rotatably mounted on the base 1. The base 1 has a hollow structure. The bracket reciprocating rotation control device includes a driven gear 12 fixedly mounted on the bracket 2 inside the base 1. The base 1 has a driving gear 13 meshing with the driven gear 12. The driving gear 13 is driven to rotate by a stepper motor 14. The bracket 2 is equipped with a cigarette weaving conveyor belt 3, which is in an up-down state. The cigarette weaving conveyor belt 3 includes two rotating shafts, each with a transmission wheel fixedly mounted on it. The transmission wheel is driven by a transmission belt. The two rotating shafts are respectively located at the top and bottom of the Y-shaped bracket 2. One of the rotating shafts is driven to rotate by a drive mechanism. Multiple cigarette weaving holding devices are spaced apart along the length of the cigarette weaving conveyor belt 3. The cigarette weaving position detection device is connected to the bracket reciprocating rotation control device and the cigarette weaving holding devices.

[0030] When using this tobacco feeding device, first, align the device with the rear wall of the tobacco curing barn and position it precisely in the middle of the tobacco stringing racks between two adjacent tobacco curing barns. Move the device straight to the innermost position of the tobacco curing barn, below the designated feeding position. Then, control the bracket 2 to rotate at a certain angle using the bracket fixed-angle reciprocating rotation control device. Simultaneously, the tobacco stringing holding device holds the tobacco string, and the tobacco stringing conveyor belt 3 transports the tobacco string above the feeding position. (Due to the rotation of bracket 2, the tobacco string is tilted relative to the tobacco stringing racks in the tobacco curing barn, allowing it to pass through the tobacco stringing racks between two adjacent tobacco curing barns. The tobacco stringing conveyor belt 3...) Figure 1 The rotation direction is from the outside to the inside at its upper end. When the tobacco weaving detection device detects the tobacco weaving, the bracket fixed angle reciprocating rotation control device controls the bracket 2 to return to the center. The tobacco weaving holding and placing device lowers the tobacco weaving, and the two ends of the tobacco weaving automatically overlap on the tobacco weaving rack in the tobacco curing room to realize tobacco loading. This device realizes fully automatic tobacco loading. The tobacco weaving holding and placing device on the tobacco weaving conveyor belt continuously loads tobacco, achieving high tobacco loading efficiency. The device has a simple structure and low cost. Afterwards, the fixed distance stopping control system controls the walking mechanism to carry the device to the position below the next tobacco loading position.

[0031] The cigarette holding device includes a cigarette conveyor belt fixed angle return control device and a cigarette lifting structure, which is vertically set on the surface of the cigarette conveyor belt.

[0032] The cigarette-making lifting structure consists of multiple steel needles 4 arranged along the width of the cigarette-making conveyor belt 3.

[0033] When the cigarette weaving detection device detects the cigarette weaving, the bracket fixed angle reciprocating rotation control device controls the bracket 2 to return to the center. Then, the cigarette weaving conveyor belt fixed angle return control device controls the drive mechanism of the cigarette weaving conveyor belt 3 to reverse, and the cigarette weaving automatically slides down from the steel needle 4 to release the cigarette. After the release is completed, the cigarette weaving conveyor belt 3 operates normally.

[0034] Another structure of the cigarette holding device is as follows: it includes two support blocks 5, one support block 5 is provided with a round hole, and the other support block 5 is provided with a plum blossom hole 6 or a square hole. One end of a round rod 7 is located in the round hole, and the other end is located in the plum blossom hole 6 or the square hole. The other end of the round rod 7 is coaxially formed with a square head 8 near its end. The square head 8 is adapted to the plum blossom hole 6 or the square hole. The round rod 7 is provided with a cigarette lifting structure. The upper end of the bracket 2 is provided with a square head separation hole driving mechanism. The plum blossom hole is a wrench plum blossom hole.

[0035] Preferably, the square-headed hole-driving mechanism is a wedge block 9, with the inclined surface of the wedge block 9 facing the round rod 7.

[0036] Alternatively, the square-headed hole-driving mechanism consists of two magnets, one of which is mounted on the round rod 7 and the other on the upper end of the bracket 2.

[0037] The cigarette-making mechanism consists of 4 steel needles, which are inserted into the cigarette.

[0038] When the cigarette-binding device holds the cigarette, one end of the round rod 7 is in the round hole, and the square head on the other end is in the plum blossom hole 6 or square hole, so that the steel needle 4 on the cigarette-binding device is perpendicular to the surface of the cigarette-binding conveyor belt 3. When the cigarette reaches the top of the cigarette-binding rack in the tobacco curing room and the support 2 returns to the center, the square head on the round rod 7 leaves the plum blossom hole 6 or square hole under the action of the inclined surface of the wedge block 9. At this time, due to the weight of the cigarette, the round rod 7 rotates and the cigarette is automatically put down. Alternatively, when the cigarette reaches the top of the cigarette-binding rack in the tobacco curing room and the support 2 returns to the center, the square head leaves the plum blossom hole 6 or square hole due to the mutual attraction or repulsion between the magnets on the round rod 7 and the support 2. At this time, the round rod 7 rotates due to the weight of the cigarette and the cigarette is automatically put down.

[0039] The lower end of bracket 2 is equipped with a square-head inlet drive mechanism.

[0040] The square-head inlet drive mechanism is a wedge block 210, with the inclined surface of the wedge block 210 facing the round rod 2.

[0041] Alternatively, the square-head inlet drive mechanism consists of two magnets, one of which is mounted on the round rod 7 and the other on the lower end of the bracket 2.

[0042] The round rod 7 and the square head 8 have a conical transition surface.

[0043] When the cigarette holding device moves to the lower end of the support, the square head on the round rod enters the plum blossom hole 6 under the action of the inclined surface of the wedge block 2 or the attraction or repulsion of the two magnets. Since there is a conical transition between the round rod 7 and the square head 8, the square head can automatically enter the plum blossom hole, so that the steel needle on the round rod is perpendicular to the surface of the cigarette conveyor belt. Of course, the square head can be manually inserted into the plum blossom hole before picking up the cigarette from the steel needle.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
