Description

Technical Field

[0001] The present invention relates to the field of flax combing machines, in particular to a combing mechanism of a flax combing machine. Background Art

[0002] Linen fabric is a very unique and high-quality textile material. The spindle-shaped structure and pectin-like beveled holes of flax fibers give linen fabric excellent moisture absorption and breathability, enabling linen fabric to regulate humidity well, keep dry and comfortable, and is especially suitable for wearing in humid or hot weather.

[0003] Flax fibers are short and uneven, making them difficult to spin. Currently, long flax spinning typically uses process fibers. Factors such as the splitting degree, pectin content, and fiber strength of these fibers are key factors affecting flax's spinnability. Combing is a key process in the flax processing process. Traditional mechanical lifting flax combs can process approximately 80 to 120 kilograms of flax per hour, with a yield of 39 to 60%. This results in low combing efficiency and a low yield. Summary of the Invention

[0004] The object of the present invention is to provide a combing mechanism for a flax combing machine.

[0005] The innovation of the present invention lies in that, by forming an angle α between the combing teeth and the axial direction of the drum, and an angle β between the steel needles and the radial extension line of the drum, and by gradually changing the angles α and β, the efficiency of combing flax fibers can be improved, and on the other hand, damage to the flax fibers during combing can be reduced.

[0006] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is:

[0007] A combing mechanism of a flax combing machine comprises at least three combing mechanisms arranged in sequence along the flax conveying direction, a driving mechanism for rotating the combing mechanisms, a clamping mechanism for clamping flax fibers, and a debris removal mechanism. The combing mechanism comprises a drum and a plurality of rows of combing teeth disposed on the drum surface, with steel needles uniformly distributed on each row of combing teeth. The combing teeth are arranged in a direction with an angle α formed with the axial direction of the drum, and the steel needles form an angle β with the radial extension of the drum. The combing teeth in each row are evenly spaced and arranged in parallel. The drum diameter of each combing mechanism increases stepwise along the flax conveying direction, the number of rows of combing teeth per unit length of each drum increases along the flax conveying direction, the angle α between the combing teeth on each drum and the axial direction of the drum decreases along the flax conveying direction, the angle α of the final combing mechanism is 0°, and the angle β between the steel needles on each drum and the radial extension of the drum is progressively deflected in the opposite direction along the flax conveying direction.

[0008] Furthermore, the clamping mechanism includes a beam arranged above the combing mechanism, a linear slide rail arranged on the beam, and a lifting drive device slidably assembled on the linear slide rail. The lower end of the lifting drive device is provided with a first hemp clamping piece and a second hemp clamping piece, and the first hemp clamping piece and the second hemp clamping piece are also respectively connected to the first directional regulating valve and the second directional regulating valve.

[0009] Furthermore, the impurity removal mechanism is arranged below one side of the combing mechanism, including a brush roller, elastic brushes evenly distributed on the surface of the brush roller, and a fiber transferor arranged on one side of the brush roller. The elastic brush is in contact with the combing teeth and the fiber transferor at the same time.

[0010] Furthermore, the surface of the drum is provided with air holes penetrating the drum wall, and the air holes are arranged between two adjacent rows of combing teeth.

[0011] The beneficial effects of the present invention are:

[0012] First: the combing teeth form an angle α with the axial direction of the drum (that is, a certain angle with the horizontal direction). At the beginning, part of the steel needles on the combing teeth comb the flax fibers, and then gradually transition to the entire plane. This design can prevent the steel needles on the combing teeth from inserting into the flax fibers at the same time. On the one hand, it can improve the efficiency of combing the flax fibers, and on the other hand, it can reduce the damage to the flax fibers during combing.

[0013] Second: the angle β between the steel needles and the radial extension line of the drum, and the angle β is deflected in a progressive reverse direction along the flax conveying direction. The density of the steel needles increases, the angle becomes smaller, and the combing effect on the flax fibers gradually increases. Thus, the combing of the flax fibers forms a gradually enhanced process, which can further reduce the damage to the flax fibers during combing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0021] A combing mechanism of a flax combing machine includes at least three combing mechanisms 10 arranged in sequence along the flax conveying direction, a driving mechanism 20 for driving the combing mechanisms 10 to rotate, a clamping mechanism 30 for clamping flax fibers 50, and an impurity removal mechanism 40. The combing mechanism 10 includes a drum 11 and a plurality of rows of combing teeth 12 arranged on the surface of the drum 11. Steel needles 13 are evenly distributed on each row of combing teeth 12. The arrangement direction of the combing teeth 12 forms an angle α with the axial direction of the drum 11. The steel needles 13 are located at an angle α to the radial extension line of the drum 11. forming an angle β; each row of combing teeth 12 is evenly spaced and arranged in parallel; the diameter of the roller 11 of each of the combing mechanisms 10 increases step by step along the flax conveying direction, the number of rows of combing teeth 12 per unit length of each roller 11 increases along the flax conveying direction, the angle α between the combing teeth 12 on each roller 11 and the axial direction of the roller 11 decreases along the flax conveying direction, the angle α of the final combing mechanism 10 is 0°, and the angle β between the steel needles 13 on each roller 11 and the radial extension line of the roller 11 is deflected in a progressive reverse direction along the flax conveying direction.

[0022] Furthermore, the driving mechanism 20 mainly includes a driving motor and a driving shaft, etc., and the driving shaft is connected to the center of each roller 11 to drive the combing mechanism 10 to rotate. This is the existing technology and will not be described in detail here.

[0023] For further reference, Figure 1 、 Figure 2 , such as 4 and Figure 5 ,in Figure 2 A five-stage combing mechanism 10 is provided. Taking the five-stage combing mechanism as an example, the parameters such as the diameter of the rollers 11 at each stage, the number of combing teeth 12 on the rollers 11, the angle α, the angle β, etc. are shown in the following table:

[0024]

[0025] The advantages of this arrangement are:

[0026] Taking the first combing mechanism as an example: since the combing teeth 12 form an angle α with the axial direction of the drum 11 (i.e., a certain angle with the horizontal direction), at the beginning, part of the steel needles 13 on the combing teeth 12 comb the flax fibers 50, and then gradually transition to the entire plane. This design can prevent the steel needles 13 on the combing teeth 12 from being inserted into the flax fibers 15 at the same time. On the one hand, it can improve the efficiency of combing the flax fibers 50, and on the other hand, it can reduce the damage to the flax fibers 50 during combing.

[0027] After the first combing mechanism completes combing, the flax fibers 50 move to the second combing mechanism, and so on. Since the diameter of each roller 11 is different and increases by 3-5 cm, the surface linear speed of the roller 11 increases, the density of the steel needles 13 increases, and the angle becomes smaller, so that the combing effect on the flax fibers 50 gradually increases.

[0028] According to tests, the original combing machine can process about 80 to 120 kilograms of flax per hour, and the combed flax yield is usually 39 to 60%; using the combing mechanism of the present application, about 110 to 140 kilograms of flax can be processed per hour, the output is increased by 20 to 30%, the combed flax yield is 52 to 70%, and the yield is increased by 8 to 12%.

[0029] Furthermore, the clamping mechanism 30 includes a beam 31 arranged above the combing mechanism 10, a linear slide rail 32 arranged on the beam 31, and a lifting drive device 33 slidably assembled on the linear slide rail 32. The lower end of the lifting drive device 33 is provided with a first hemp clamping piece 34 and a second hemp clamping piece 35. The first hemp clamping piece 34 and the second hemp clamping piece 35 are also respectively connected to the first direction regulating valve 36 and the second direction regulating valve 37.

[0030] Furthermore, the lifting drive device 33 is an existing technology and can be directly purchased on the market, such as a hydraulic lever, a cylinder, etc., and is mainly used to control the lifting of the flax fibers 50.

[0031] For further reference, Figure 3The electromagnetic valve controls the first clamping piece 34 and the second clamping piece 35 to clamp the upper end of the flax fiber 50, and then the lifting drive device 33 drives the flax fiber 50 to descend, so that the combing mechanism 10 can comb the flax fiber 50. After the first combing mechanism has finished combing, the lifting drive device 33 lifts the flax fiber 50 and moves it along the linear slide rail 32 to transport the flax fiber 50 to the top of the second combing mechanism 10. Then the lifting drive device 33 drives the flax fiber 50 to descend again, so that the second combing mechanism 10 can comb the flax fiber 50. And so on. When the final combing mechanism 10 has finished combing the flax fiber 50, the flax fiber 50 is combed. The fibers 50 complete the first pass of combing. The solenoid valve controls the second clamping piece 35 to release its grip, and the first clamping piece 34 begins to rise. After reaching its highest point, the second clamping piece 35 clamps the lower end of the flax fiber 50. The first clamping piece 34 releases its grip, and the second clamping piece 35, under the action of the second directional control valve 37, flips over to above the first clamping piece 34 (diverting the flax fiber 50). The flax fiber 50 is then fed into the combing mechanism 10 again for combing (combing the other end of the flax fiber 50). In this application, the first and second clamping pieces 34, 35, and directional control valves are utilized to achieve multiple passes of combing of the flax fiber 50. Furthermore, the connection method between the first and second clamping pieces 34, 35 and the lifting drive device 33 is conventional and will not be further described here.

[0032] Furthermore, the impurity removal mechanism 40 is arranged below one side of the combing mechanism 10, and includes a brush roller 41, an elastic brush 42 evenly distributed circumferentially on the surface of the brush roller 41, and a fiber transferor 43 arranged on one side of the brush roller 41. The elastic brush 42 simultaneously forms contact cooperation with the combing teeth 12 and the fiber transferor 43.

[0033] Furthermore, the surface of the drum 11 is provided with air holes 14 penetrating the drum wall, and the air holes 14 are arranged between two adjacent rows of combing teeth 12 .

[0034] Furthermore, air holes 14 are provided, the main function of which is to blow the flax fibers 50 away from the surface of the drum 11 after the combing is completed.

[0035] The embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
