Technical Field

[0001] The invention belongs to the technical field of spinning, and in particular relates to a visual detection device for a traction roller. Background Art

[0002] In the textile industry, the post-spinning short-process production line is an important equipment for producing high-quality fibers and yarns. In the traditional post-spinning production line, the tow needs to be heated before drawing to improve its drawability and quality after drawing. However, the traditional heating method mostly uses water bath heating, which has many shortcomings. First, the temperature control of water bath heating is not precise enough to meet the heating temperature requirements of different tow materials and processes. Secondly, the water bath heating equipment occupies a large area, which is not conducive to the compact layout and efficient operation of the production line. In addition, the maintenance and cleaning of the water bath heating equipment are also relatively complicated, which increases production costs and downtime.

DETAILED DESCRIPTION

[0013] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0014] like Figures 1 to 3As shown, the present invention provides a post-spinning short-process production line, which includes a creel 1, a pre-finishing unit 2, a drafting unit 4, a traction machine 5, a crimping machine 6, a belt conveyor 7, a swinging wire machine 8, an oven 9, a tension machine 10, a cutting machine 11 and a baling machine 12 arranged in sequence along the production direction. Furthermore, a heating device 3 is arranged between the pre-finishing unit 2 and the drafting unit 4 to heat the tow so as to facilitate the subsequent drafting of the tow. Among them, the heating device 3 includes a plurality of axially rotating wheel discs 31, each of which is rotatably arranged on a frame 17 through a bearing 16, and each wheel disc 31 is provided with a plurality of mutually parallel heating rollers 32. A plurality of heating rollers 32 surround the axis of the wheel disc 31 and are arranged on the wheel disc 31 at equal intervals. The interior of the heating roller 32 is provided with an electric heating wire (not shown) for heating the heating roller 32. The present invention uses electric heating instead of traditional water bath heating, which can achieve precise temperature regulation and stable temperature maintenance, and occupies less space and is easy to maintain and clean. When in use, the wheel 31 rotates, driving a plurality of heating rollers 32 to rotate around the axial direction of the wheel 31. The rotation direction of the wheel 31 is opposite to the traveling direction of the filament bundle 18. The filament bundle 18 contacts the heating roller 32 passing the top of the wheel 31 and is heated by the heating roller 32. When the temperature of the heating roller 32 is too high, as the turntable 31 rotates, the filament bundle 18 contacts the cooled heating roller 32 in turn, thereby gradually reducing the temperature.

[0015] Furthermore, the wheel disc 31 is provided with a main shaft 33 for driving the wheel disc 31 to rotate, the main shaft 33 is connected to a driving device 13, the driving device 13 includes a motor 131, and the output shaft 132 of the motor 131 and the main shaft 33 are both provided with a sprocket 14, and the sprocket 14 is meshed and connected with a chain 15. When in use, the output shaft 132 of the motor 131 rotates, driving the sprocket 14 on the output shaft 132 to rotate, and the chain 15 meshes with the sprocket 14 to drive the sprocket 14 on the main shaft 33 to rotate, so that the wheel disc 31 rotates, and the tow 18 is heated.

[0016] Furthermore, the number of teeth of the sprocket 14 provided on the main shaft 33 decreases along the production line direction. The present invention utilizes the different numbers of teeth of the sprocket 14 to make the rotation speeds of the sprockets 14 with different numbers of teeth inconsistent, so that the rotation speeds of each wheel disc 31 are different. The closer the wheel disc 31 is to the pre-finishing machine 2, the slower the rotation speed, the slower the contact between the tow 18 and the heating roller 32 passing through the highest point of the wheel disc 31, and the lower the heating temperature; the closer the wheel disc 31 is to the drawing unit 4, the faster the rotation speed, the faster the contact between the tow 18 and the heating roller 32 passing through the highest point of the wheel disc 31, and the higher the heating temperature. The different rotation speeds of the wheel disc 31 are utilized to achieve a gradual increase in the heating temperature of the tow 18 when it is transported to the drawing unit 4.

[0017] Further, the drafting machine group 4 includes a plurality of drafting machines, each of which includes a first drafting roller 41 and a second drafting roller 42 arranged vertically on a drafting machine frame 43. Each drafting machine has a first drafting roller 41 or a second drafting roller 42 arranged obliquely, and a plurality of first drafting rollers 41 and second drafting rollers 42 are alternately inclined on the drafting machine frame 43 to facilitate drafting of the tow.

[0018] When the present invention is in use, after the tow 18 comes out of the creel 1, it enters the pre-finishing unit 2, performs preliminary finishing on the tow 18, and then enters the heating device 3, and heats the tow 18 to reach a certain temperature to soften the fiber, which is convenient for subsequent drawing and curling operations. After the heating device 3, the tow 18 enters the drawing unit 4, and the tow 18 passes through the first drawing roller 41 and the second drawing roller 42 of each group of drawing machines in turn. Through mechanical stretching, the tow becomes thinner and more uniform, and its strength and elasticity are increased. The stretched tow 18 is pulled by the traction machine 5 to keep the tow 18 moving forward steadily on the production line. The tow 18 enters the crimping machine 6 under the traction of the traction machine 5, and the crimping machine curls the tow to increase the fluffiness and feel of the tow; the curled tow 18 is transported by the belt conveyor 7 and enters the swinging wire machine 8, and the swinging wire machine 8 evenly distributes the tow 18 in the subsequent drying oven 9 by swinging to avoid the accumulation or uneven distribution of the tow; the tow 18 enters the drying oven 9 for drying to make the tow reach a certain degree of dryness; then the tow 18 enters the tensioning machine 10 to adjust the tension of the tow 18. After the adjustment of the tensioning machine 10, the tow 18 enters the cutting machine 11 for cutting. The cutting machine 11 cuts the tow into segments of a certain length according to production requirements. The cut tow 18 enters the baling machine 12 for baling.

[0019] The creel 1, pre-finishing unit 2, traction machine 5, crimping machine 6, belt conveyor 7, wire swing machine 8, oven 9, tension machine 10, cutting machine 11 and baling machine 12 in the present invention are existing structures in the art, and can be adaptively selected when used based on their functions.

[0020] The post-spinning short-process production line provided by the present invention introduces a heating device 3, adopts a design of a rotating wheel 31 and a heating roller 32, and continuously heats through an electric heating wire to maintain a stable heating temperature, thereby achieving precise heating and stable temperature maintenance of the filament bundle 18. The heating device 3 has a compact structure and occupies a small area, which is conducive to the compact layout and efficient operation of the production line, is easy to maintain, and does not require the treatment of waste water and dirt in water bath heating, thereby reducing production costs and saving time.
