Description

Technical Field

[0001] The invention relates to a dual-channel lotus root silk automatic extraction device comprising a frame, a feeding unit, a lotus root stem transmission unit, a lotus root stem silk drawing unit and a lotus root silk collecting unit, and belongs to the technical field of lotus root stem silk extraction and agricultural product processing equipment. Background Art

[0002] Lotus root fiber, also known as lotus root fiber, refers to the naturally grown and elongated fibers of the tubular molecules in the secondary wall of the lotus stem (the stem between the lotus leaf or lotus pod and the lotus root). It is a natural material that is widely used in the textile, food, and chemical industries. Lotus root silk is the main material for ink pads, and its product "Longquan ink pad" is more valuable than gold. The market for lotus root silk products is vast, but the raw material lotus root silk is in short supply. Therefore, it is urgent to develop equipment for extracting lotus root silk and effectively utilize lotus root silk resources.

[0003] At present, there are several methods for extracting lotus root silk: (1) Manual silk drawing in small workshops. Craftsmen directly break the lotus root stems and collect the lotus root silk manually. The advantage is that the operation is simple, but the disadvantage is that manual silk drawing is time-consuming and labor-intensive, with high labor costs and low efficiency. In addition, the freshly harvested lotus root stems must be quickly broken for silk drawing. Once the lotus root stems are dehydrated, it is difficult to draw silk. (2) Automatic silk drawing machine for lotus root stems. Patent CN202211071431.8 uses a single-channel propulsion motor for feeding movement, a rotating motor cooperates with a tool for cutting, and the lotus root silk is collected by winding the silk collecting claw. The disadvantages of this type of device are: first, it is necessary to manually fill the lotus root stems and manually clean the waste lotus root stems, and the single-channel design can only process one lotus root stem at a time, with high labor costs and low efficiency; second, the lotus root stems are not cleaned and moisturized, and the silk drawing effect is not good after the lotus root stems are dehydrated; third, the cylindricality of the lotus root stems themselves is required to be high, and a large number of propulsion motors are used, the equipment is relatively complex, and the cost and maintenance cost are high; fourth, the silk collecting claw is easy to lose silk, and it is impossible to collect all the exposed lotus root silk.

[0004] In order to overcome the above problems, the present invention discloses a dual-channel automatic extraction device for lotus root silk, which comprehensively considers and upgrades the shortcomings of the above two methods of extracting lotus root silk, and innovatively adopts an automatic feeding unit integrating cleaning and temperature control functions, a dual-channel lotus root stem transmission unit with high efficiency and good adaptability, a lotus root stem silk drawing unit with high compatibility, and a lotus root silk collection unit with high lotus root silk collection rate. It not only ensures the freshness of the lotus root stem to improve the silk drawing effect, but also improves the lotus root silk extraction efficiency and enhances the practicality of the device. Summary of the invention

A dual-channel lotus root silk automatic extraction device is provided. The automated feeding unit can reduce manual operation, the cleaning pool can moisturize the lotus root stems to ensure a good silk drawing effect of the lotus root stems, the dual-channel lotus root stem transmission unit improves the silk extraction efficiency, the elastic pick improves the compatibility of the device, and the complex silk winding trajectory of the silk collecting rod ensures the lotus root silk collection effect.

Through the mutual cooperation of the five units, the lotus root silk is finally collected on the silk collecting rod 5026, and the collected lotus root silk is taken down by the user.

[0064] Furthermore, the frame 1 includes a base 101, a side mounting frame 102, a top mounting frame 103, a control console 104, and a visual sensor 105; the base 101 is located at the bottom of the device; the side mounting frames 102 are arranged on the left and right sides of the base; the top mounting frame 103 is arranged on the top of the device; the control console 104 is arranged on the top mounting frame to control the operation of the device; the sensor 105 is arranged on the side mounting frame 102 to monitor the position of the lotus stem;

[0066] The feeding bin 201 is welded on the top mounting frame 103, and is divided into two layers, an upper and lower layer, and is provided with a lotus stem feed port A located on the top left side of the feeding bin 201. The left side of the upper layer of the feeding bin 201 is a cleaning pool, which is filled with cleaning liquid of appropriate depth. A pair of air inlets D are located on the left side of the upper layer of the feeding bin 201.

[0077] The cutting module 404 includes a motor 4041, a bearing seat 4042, a small gear 4043, a large gear 4044, an annular guide groove 4045, a front tool mounting seat 4046, a rear tool mounting seat 4047, a tool arm 4048, and a tool 4049;

[0078] The motor 4041 is assembled on the top of the mounting column 402 by bolt connection, and its output shaft is connected with the pinion 4043 through the bearing seat 4042, and drives the pinion 4043 to rotate, and the pinion 4043 is meshed with the large gear 4044 for transmission; the large gear 4044 is mounted on the fixed shaft 403 by clearance fit, and four solid steel bars are welded on its end face, and the solid steel bars pass through four small holes evenly distributed along the circumferential direction on the front tool mounting seat 4046 and are welded on the rear tool mounting seat 4047; the annular guide groove 4045 is welded on the front tool mounting seat 4046, and a three-quarter spherical guide groove is opened on its circumference; the tool arm 4048 is assembled on the front tool mounting seat 4046 and the tool 4049 by bolt connection; the tail of the tool 4049 is assembled on the rear tool mounting seat 4047 by bolt connection, and the cutting angle of the tool 4049 can be adjusted with the linear movement of the annular guide groove 4045;

[0079] The engagement between the pinion 4043 and the large gear 4044 drives the entire cutting module 404 to rotate, and cooperates with the cutter 4049 to complete the circumferential cutting function. The tooth thickness of the pinion 4043 is significantly thicker than that of the large gear 4044, so that the large gear 4044 has linear movement space;

[0080] The crank slider module 405 includes a motor 4051, a bearing seat 4052, a pinion 4053, a large gear 4054, a connecting rod 4055, and a spherical slider 4056; the motor 4051 is assembled on the mounting column 402 in a bolted manner, and its output shaft is connected to the pinion 4053 through the bearing seat 4052; the pinion 4053 is meshed with the large gear 4054 for transmission; the large gear 4054 is connected to the spherical slider 4056 through the connecting rod 4055, and transmits power to the spherical slider 4056; the spherical slider 4056 is installed in the annular guide groove 4045, and is bound by the three-quarter spherical guide groove on the annular guide groove 4045.

[0082] When the lotus stem is transmitted to the elastic pick 4032 at the front end of the fixed shaft 403 by the lotus stem transmission unit 3, the hand-held trumpet-shaped elastic pick 4032 can guide the lotus stem to enter in the center, and the barbs on it can prevent the lotus stem from sliding out. At the same time, the crank slider module 405 can drive the annular guide groove 4045 and the front tool mounting seat 4046 to squeeze the rear tool mounting seat 4047, so that the rear tool mounting seat 4047 pushes forward to squeeze the elastic pick 4032 at the front end of the fixed shaft 403 and deforms and tightens it, completing the clamping of the lotus stem. Then the cutting module 404 rotates so that the tool 4049 performs annular cutting of the lotus stem epidermis at an appropriate depth, and then the linear moving module 401 moves backward, so that the lotus stem cut in annular form is pulled off, exposing the lotus root silk. When the lotus root silk collecting unit 5 has collected all the lotus root silk, the crank slider module 405 drives the annular guide groove 4045 and the front mounting seat 4046 of the cutter to leave the rear mounting seat 4047 of the cutter. The rear mounting seat 4047 of the cutter slides back naturally after being freed from force, so that the elastic paddle 4032 is relaxed, and the waste lotus root stems are released. At this time, the waste material processing module 406 sprays air to blow out the waste lotus root stems, waiting for new lotus root stems to be filled in;

[0083] Furthermore, the lotus root silk collection unit 5 includes a scissor-type lifting platform 501 and a lotus root silk extraction mechanism 502;

[0087] The lotus root silk extraction mechanism 502 drives the rotating arm 5023 through the rotating motor 5022, so that the silk collecting rod 5026 realizes the rotational movement of the hourglass-shaped space trajectory around the central axis a, and at the same time, the self-rotating motor 5028 drives the silk collecting rod 5026 to rotate; the burr-containing part of the silk collecting rod 5026 is the working end, and the lotus root silk can be collected at the burr part along the complex trajectory generated by the turnover and self-rotation of the silk collecting rod 5026;

[0088] The scissor-type lifting platform 501 falls to a permanent state. When the lotus root stems are exposed to lotus root silk by the lotus root stem silk drawing unit 4, the scissor-type lifting platform 501 rises, and the lotus root silk extraction mechanism 502 works to collect the exposed lotus root silk. When a section of lotus root silk is collected, the scissor-type lifting platform 501 falls, and the cycle continues.
