Description

Technical field:

[0002] The utility model relates to a counting type tobacco leaf distance cutting device, which is used for cutting the distance of iron wires passing through tobacco leaves. Background technology:

[0004] Cigar tobacco leaves need to be hung during the drying process. Currently, people use special drying and unloading rods to weave and unload tobacco leaves. However, the drying and unloading rods need to be machine-processed, with a long production cycle, and usually need to be customized six months in advance. In case of some emergencies (such as wind disasters, tobacco root and stem diseases will increase sharply with rising temperatures, and tobacco leaves need to be picked and dried as soon as possible), it is impossible to produce a large number of drying and unloading rods in a short period of time. To overcome the above contradictions, cotton thread is currently used to thread tobacco leaves, but this method has low weaving efficiency and is prone to tobacco rot during the drying process.

[0005] To this end, tobacco farmers considered using No. 22 iron wire to string dozens of tobacco leaves, then fixing the two ends of the iron wire strung with tobacco leaves on the two ends of a metal rod, and alternately placing two adjacent tobacco leaves on both sides of the metal rod, so that the metal rod can support most of the weight of the tobacco leaves. However, the iron wire strung with tobacco leaves needs to be cut to a fixed length. In the past, these iron wires needed to be measured for length one by one before being cut, which resulted in low work efficiency and problems such as length differences among the iron wires.

[0006] In order to solve the problem of low efficiency in measuring and cutting wire, the applicant applied for a Chinese patent "Tobacco Wheel-Type Fixed-distance Wire Cutter" in July 2024, application number 202422051844.0. The fixed-distance wire cutter needs to be manually driven and the number of revolutions of the turntable needs to be manually counted, which also increases the manual workload. Summary of the invention:

[0008] In view of the above problems, the purpose of the present invention is to provide a counting tobacco leaf fixed-length wire cutter, which has a reasonable design, can reduce the workload and further improve the efficiency of tobacco farmers in cutting fixed-length wire.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] The utility model discloses a counting type tobacco leaf fixed distance thread trimmer, which comprises a base 1, a first supporting frame 2 arranged on the right side of the base 1 and a second supporting frame 3 arranged on the left side of the base 1.

[0028] The base 1 includes two parallel bottom longitudinal bars 101 and two parallel bottom cross bars 102 vertically arranged between the two bottom longitudinal bars. A reinforcing bar 103 is vertically arranged between the two bottom cross bars. The bottom longitudinal bars 101, the bottom cross bars 102 and the reinforcing bar 103 can all be made of square steel.

[0029] The first support frame 2 includes two vertical support square steels 4 arranged in parallel and perpendicular to the base. The upper part between the two vertical support square steels 4 is rotatably connected to the rotating shaft 6 of the first turntable 5, and the two ends of the rotating shaft 6 are rotatably hinged to the upper part of the vertical support square steels 4.

[0030] The first support frame 2 is rotatably connected to a first turntable 5 for winding the iron wire, and the rotation axis centerline of the first turntable 5 (that is, the axis centerline of the rotating shaft 6) is parallel to the ground. The first turntable 5 includes a circular outer frame 7 made of steel bars (or round steel) and a second connecting bar 8 radially evenly distributed in the circular outer frame. The second connecting bar 8 has four to six, and the first end of the second connecting bar 8 is fixedly connected to the circular outer frame 7, and the second end of the second connecting bar is fixedly connected to the rotating shaft 6 of the first turntable. A first sprocket 9 is connected to the rotating shaft 6 of the first turntable 5 to drive the first turntable 5 to rotate. A motor 10 and a second sprocket 11 driven by the motor to rotate are provided on the base. The first sprocket and the second sprocket are connected by a chain 12. Under the drive of the motor, the second sprocket 11 and the first sprocket 9 rotate, driving the rotating shaft 6 and the circular outer frame 7 to rotate, and then winding the iron wire on the circular outer frame 7 (specifically, it is limited by subsequent groove-shaped limiting ribs).

[0031] A photoelectric counter 13 and an infrared photoelectric sensor 25 electrically connected to the photoelectric counter are fixedly provided on the first support frame 2. The infrared photoelectric sensor 25 is directly opposite to the first sprocket 9. The photoelectric counter and the infrared photoelectric sensor are commercially available components. Their internal structure will not be described here. Their working principle is also a common technology. When the first sprocket rotates, the number of rotations will be sensed by the infrared photoelectric sensor and recorded and displayed by the photoelectric counter (that is, the infrared light is interrupted and recorded by the photoelectric counter, and displayed on the display screen at the same time). The user can know how many fixed-length iron wires have been wound by checking the displayed value of the photoelectric counter, thereby facilitating operation and use.

[0032] The winding wire is wound on the outer circumference of the first turntable 5. The circumference of the outer circumference of the first turntable 5 is 2.2-2.6 meters. To meet the needs of use, the circumference of the outer circumference of the first turntable 5 is preferably 2.5 meters. The second support frame 3 is rotatably connected to a wire ring for sleeved (a commercially available part, usually 200-300 meters of wire wound, and the circumference of one circle is about 50-150 cm).

[0033] In order to facilitate cutting, a disconnection portion 14 is provided on the circular outer frame 7 between two adjacent second connecting strips, that is, a section of the steel bar or round steel used to make the circular outer frame is disconnected. When in use, scissors are inserted into the disconnection portion to cut the wound wire, making cutting more convenient and quick.

[0034] The second support frame 3 includes a first column 15 and a second turntable 16 rotatably connected to the upper end of the first column. The rotation axis of the second turntable 16 is perpendicular to the ground. A plurality of limiting rods 17 are evenly distributed in the circumferential direction on the upper surface of the second turntable. The wire loop is wrapped around the outer periphery of each limiting rod. The second turntable can be a rectangular or circular plate, and a bearing 18 can be installed in the center of the plate. The bearing is sleeved on the center rod 19 at the upper end of the first column.

[0035] The outer side of the circular outer frame 7 is provided with groove-shaped limiting ribs 20 . The groove-shaped limiting ribs 20 are formed by bending long steel bars into a V shape. The bending angle of the long steel bars is greater than or equal to 90 degrees and less than 150 degrees.

[0036] In order to facilitate the guidance of the iron wire, a plurality of guide holes 21 are fixedly provided on the base 1 between the first support frame and the second support frame. Each guide hole is provided on the upper part of the second column 24. When in use, the end of the iron wire is output from the second turntable, passes through the guide hole and then is wound around the first turntable. The setting height of the guide hole can be adjusted, and the guide holes are provided in different positions to reduce the bending of the iron wire.

[0037] In order to improve the stability of the wire winding, a third column 22 is provided on the base 1 beside the limiting pole, and a sponge column (or rubber rod) 23 is connected to the third column. The first end of the sponge column or rubber rod is fixed on the third column, and the second end of the sponge column is in contact with the upper part of the limiting pole. When the second turntable rotates, the sponge column will be moved, but the sponge column will still return to its original position. This reciprocating process can buffer the rotation of the second turntable and prevent the wire ring from falling out.

[0038] The utility model discloses a counting-type tobacco leaf fixed-distance wire cutter. The working method comprises the following steps: putting a whole roll of commercially available wire ring (a whole roll of commercially available wire ring is 200-300 meters) on a second turntable, then pulling out one end of the wire ring and fixing it at a certain position of the outer circumference of the first turntable (any position on the circumference of the outer circumference of the first turntable, which is defined as point A), then starting a motor to drive the second sprocket, the chain, the first sprocket and the first turntable to rotate, so that the wire ring is gradually rotated onto the first turntable (if 100 wires are required, the first turntable rotates 100 times, and the number of rotations can be obtained from the display screen of a photoelectric counter), finally using scissors to cut all the wires wound on the first turntable at the point A position at once, and straightening the cut wires. The length of the straightened wires is the circumference of the outer circumference of the first turntable, and the circumference is also the required fixed length of the wire (between 2.2 and 2.6 meters).
