Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an automatically cleanable wire drawing machine for yarn. Background Art
[0002] Wire drawing machine is a kind of mechanical equipment that processes raw materials into filaments. It is mainly used in the textile industry. The working principle of the wire drawing machine is to gradually draw the raw materials into filaments through a series of stretching and winding. These filaments can be used for subsequent processing such as weaving, spinning, webbing, and manufacturing fiber products.
[0003] Existing yarn drawing machines are usually equipped with a group of roller structures for stretching the yarn. For processing thinner yarns, the processing effect is very limited. When the surface of the roller structure needs to be cleaned, the entire wire drawing machine needs to stop working until all the rollers of the wire drawing machine are cleaned, which greatly affects the working efficiency of the wire drawing machine. At the same time, current wire drawing machines are generally equipped with a take-up roller. After the take-up roller is wound, the take-up roller needs to be disassembled and replaced with a new one to work. The wire drawing machine needs to be stopped during the disassembly and replacement of the take-up roller, thereby reducing the efficiency of the entire wire drawing machine in processing yarn. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a yarn drawing machine that can be automatically cleaned.
[0005] The technical solution adopted to solve the above technical problems is: a yarn drawing machine that can be automatically cleaned, comprising a support frame, a main frame and a rotating disk arranged at the bottom of the support frame, an opening and closing bin mechanism is arranged on one side inside the main frame, a stretching mechanism is arranged inside the bin body of the opening and closing bin mechanism, a cleaning mechanism is arranged on the outside of the bin body of the opening and closing bin mechanism, a heating mechanism is arranged at the middle position inside the bin body of the opening and closing bin mechanism, a displacement mechanism that cooperates with the stretching mechanism is arranged on one side of the main frame, a yarn adjusting mechanism is arranged at the top and bottom of the bin body of the opening and closing bin mechanism, a guiding mechanism and a winding mechanism are arranged on one side inside the main frame, a wire feeding mechanism is arranged at the bottom of the main frame, and a tightness adjusting mechanism is arranged at the top of the main frame; The opening and closing bin mechanism includes an installation bin located in the middle position of one side inside the main frame, a side panel is inserted into one end of the main frame close to the installation bin, electric telescopic rods are symmetrically installed at one end of the top and bottom of the main frame, and the output ends of the two groups of electric telescopic rods pass through the main frame and are fixedly connected to the outer side of the side panel, and a wire outlet is opened at the bottom of one side of the installation bin.
[0006] Furthermore, the stretching mechanism includes a mounting frame, which is provided with four groups, and the four groups of mounting frames are symmetrically arranged inside the mounting bin, a pair of wire drawing rollers are arranged inside the mounting frame, four groups of first servo motors are evenly installed at one end of the main frame, and the output ends of the four groups of first servo motors are respectively connected to one of the adjacent pair of wire drawing rollers through a connecting shaft.
[0007] Through the above technical scheme, after the yarn is heated, the four groups of first servo motors are controlled to drive a group of wire drawing rollers connected to them to rotate through the connecting shafts, and the speed difference between the bottom two groups of first servo motors and the top two groups of first servo motors is used to stretch the yarn between the four pairs of wire drawing rollers, and the speed of the top two groups of first servo motors always remains the same.
[0008] Furthermore, the cleaning mechanism includes a connecting frame located at one end of the mounting bin, four pairs of movable frames are symmetrically installed at the top and bottom of the connecting frame near one end of the side plate, and each pair of movable frames extends to the interior of the mounting bin away from one end of the connecting frame and is installed with a brush for cleaning the surface of the wire drawing roller, two groups of first sliding rods are installed at the middle position of the mounting bin near one end of the connecting frame, and a cross plate is jointly mounted on the two groups of first sliding rods, and a first electric push rod is installed at the middle position of the main frame near one end of the connecting frame, and the output end of the first electric push rod is fixedly connected to the cross plate.
[0009] Through the above technical scheme, the first electric push rod is controlled to cooperate with the cross plate to push the connecting frame to move, so that the brush at one end of the movable frame moves from the area originally cleaning half of the surface of the drawing roller to the other half, and accompanied by the subsequent rotation of the drawing roller, the brush automatically cleans the surface of the drawing roller. During the process, the cross plate slides on the first slide bar, and the half area of the drawing roller surface originally cleaned by the brush can continue to stretch the yarn, thereby ensuring the processing efficiency of the entire drawing machine.
[0010] Furthermore, the heating mechanism includes a partition located at a middle position inside the installation bin, two groups of infrared heating devices are symmetrically installed on both sides of the partition, and baffles are symmetrically installed on the tops of both sides of the partition.
[0011] Through the above technical scheme, the infrared heating device is controlled to heat the yarn passing through both sides of the partition, which helps the four pairs of drawing rollers to stretch the yarn, and the baffle can block the impurities generated during the brush cleaning the surface of the drawing roller, preventing the impurities from affecting the normal operation of the infrared heating device.
[0012] Furthermore, the displacement mechanism includes a limiting slide groove, which is symmetrically opened on the same side at both ends of the mounting frame, a limiting slide is arranged inside the limiting slide groove, and a first bearing is installed inside the limiting slide, and the rotating shafts at both ends of a group of the drawing rollers are respectively fixedly connected to the inner rings of the two adjacent groups of first bearings, and a movable strip plate is commonly installed on the outer sides of the two groups of limiting slide blocks at the same end, and the four groups of movable strip plates extend to the outer side of the main frame away from the side of the mounting frame and are commonly installed with a connecting plate, and return springs fixedly connected to the outer side of the main frame are symmetrically installed at the four corners of the inner side of the connecting plate, a strip limiting hole is opened on the outer side of the movable strip plate, and a strip limiting block cooperating with the connecting plate is installed on one end of the side plate away from the main frame.
[0013] Through the above technical solution, after the electric telescopic rod is extended and drives the side panel to move and thus opens one side of the installation bin, the strip limit block pushes the connecting plate closer to the main frame, and the elastic force of the reset spring forces the connecting plate to drive the two pairs of movable strips to move outward from the inside of the installation bin, and the movable strips will drive one of each pair of drawing rollers away from the other, so that each pair of drawing rollers no longer has a clamping effect on the yarn. During the process, the limit slider slides in the limit slot, and the strip limit hole prevents the rotating shaft of a group of drawing rollers whose position in the installation frame will not move from affecting the movement of the movable strips. When the electric telescopic rod is controlled to be shortened, the reset spring is shortened by force and stores elastic potential energy. At this time, the two groups of drawing rollers in the installation frame are tightly attached to and clamp the yarn.
[0014] Furthermore, the yarn adjusting mechanism includes an L-shaped connecting frame, which is provided with two groups of L-shaped connecting frames, and the two groups of L-shaped connecting frames are respectively arranged at the top and bottom of one side of the side plate, and movable frames are symmetrically installed on both sides of the L-shaped connecting frame near one end of the mounting bin, and the movable frame extends to the inside of the mounting bin away from one end of the L-shaped connecting frame and is installed with a guide wheel, and two groups of second sliding rods are symmetrically installed on the top and bottom of the mounting bin near one end of the L-shaped connecting frame, and the two groups of second sliding rods pass through an adjacent group of guide wheels, and a driven rack is installed at the bottom of the L-shaped connecting frame, and an active rack is symmetrically installed at the top and bottom of the connecting frame, and transmission gears that mesh with the driven rack and the active rack are symmetrically arranged at the top and bottom of the main frame near one end of the connecting frame.
[0015] Through the above technical solution, when the first electric push rod cooperates with the cross plate to push the connecting frame toward the installation bin, the two sets of active racks at the top and bottom of the connecting frame will drive the transmission gear to rotate, and the transmission gear will drive the L-shaped connecting frame to automatically move away from the installation bin through the driven rack. During the process, the L-shaped connecting frame slides on the second slide rod, and then the movable frame and the four sets of wire wheels drive the yarn to move together, so as to adjust the position of the yarn passing through the outside of the drawing roller, so that the area on the outside of the drawing roller that stretches the yarn will not be cleaned by the brush, while the brush will clean the area on the outside of the drawing roller that does not stretch the yarn.
[0016] Furthermore, the guiding mechanism includes two groups of third sliding bars located at both ends of one side inside the main frame, and a lifting frame is commonly sleeved on the outer sides of the two groups of third sliding bars, a pair of second guide wheel groups are arranged inside the lifting frame, and a pair of third guide wheel groups are arranged on one side of the bottom of the lifting frame, and a pair of first guide wheel groups cooperating with the second guide wheel groups are installed at the bottom end of the side plate close to the lifting frame, and a pair of limit blocks cooperating with the lifting frame are installed at the middle position of the side plate close to the first guide wheel group.
[0017] Through the above technical solution, when the winding mechanism drives the lifting frame to rise, the lifting frame slides on the two sets of third slide bars during the process, and the continuously processed yarn is temporarily stored by increasing the distance between the first guide wheel group and the second guide wheel group. During this process, the operator can operate to replace a new set of rollers to reel in the yarn, and when the lifting frame descends, the limit block limits the minimum height of the lifting frame to descend, and the yarn is guided by the first guide wheel group, the second guide wheel group and the third guide wheel group, so that the yarn is finally reeled in by the winding roller.
[0018] Furthermore, the winding mechanism includes a screw rod, which is provided with two groups, and the two groups of screw rods are located at both ends of the inside of the main frame close to the first guide wheel group. The outer sides of the two groups of screw rods are commonly threaded with a lifting plate, and the two ends of the top of the lifting plate are symmetrically provided with winding rollers, and the two sides of the bottom of the lifting plate are symmetrically installed with a second servo motor connected to the winding roller for transmission. The top ends of the two groups of screw rods extend to the top of the main frame and are installed with synchronous wheels, and the outer sides of the two groups of synchronous wheels are commonly provided with synchronous belts, and the top of the main frame is installed with a third servo motor connected to the top of an adjacent group of screw rods.
[0019] Through the above technical scheme, the third servo motor is controlled to cooperate with the synchronous wheel and the synchronous belt to drive the two sets of screws to rotate, and the thread action is used to force the lifting plate to continuously perform reciprocating lifting motion. During the process, the second servo motor is controlled to drive the winding roller to rotate and wind the yarn. Since the lifting plate continuously performs reciprocating lifting motion, the yarn can be evenly wound on the winding roller.
[0020] Furthermore, the wire feeding mechanism includes two groups of second bearings located in the middle position of the bottom of the main frame, the inner rings of the two groups of second bearings are jointly installed with wire tubes, and the inner top and inner bottom of the wire tubes are both provided with funnel openings, a driven gear is installed at the bottom end of the outer side of the wire tube, a driving motor is installed at the bottom of the main frame, and a driving gear meshing with the driven gear is installed at the output end of the driving motor.
[0021] Through the above technical scheme, the driving motor is controlled to cooperate with the driving gear and the driven gear to drive the wire tube to rotate, and the inner wall of the wire tube and the funnel mouth is used to bring the surface fibers of the passing yarn close to the yarn body, so as to avoid uneven heating of the surface fibers of the yarn when the subsequent infrared heating device heats the yarn.
[0022] Furthermore, the tightness adjustment mechanism includes a second electric push rod located in the middle of the top of the main frame, an L-shaped top frame is installed at the output end of the second electric push rod, and the bottom end of the L-shaped top frame extends to the inner top of the installation bin and is installed with a lifting guide roller.
[0023] Through the above technical solution, the second electric push rod is controlled to drive the L-shaped top frame to rise or fall, thereby controlling the lifting and lowering of the lifting guide roller, thereby adjusting the tightness of the yarn inside the installation bin to ensure the stretching effect of the subsequent device on the yarn.
[0024] The beneficial effects of the present invention are as follows: (1) The present invention provides two pairs of drawing rollers for stretching the yarn on both sides of the partition, and cooperates with the infrared heating devices on both sides of the partition to perform two stretching processes on the yarn, which can not only meet the demand for processing thinner yarns, but also complete the amount of stretching required by the original group of yarn stretching structures through the two groups of yarn stretching structures, thereby helping to improve the processing efficiency of the yarn by the entire drawing machine; (2) The present invention releases the clamping effect of the two adjacent groups of drawing rollers on the yarn through the cooperation of the opening and closing bin mechanism and the stretching mechanism, and the yarn adjustment mechanism adjusts the position of the yarn on the drawing roller, so that the yarn moves from the half area outside the drawing roller to the other half area, and then the yarn can continue to be stretched by the stretching mechanism in cooperation with the heating mechanism. During the process, the cleaning mechanism cleans the half area of the surface of all drawing rollers away from the yarn. By cleaning the surface of the drawing roller in two parts, the automatic cleaning of the drawing roller can be achieved and the processing efficiency of the yarn by the drawing machine can be guaranteed; (3) The present invention cooperates with the guiding mechanism and the winding mechanism. During the process of replacing the winding roller to wind the yarn, the height of the second guide wheel group and the third guide wheel group is raised to ensure the tightness of the yarn between the second guide wheel group and the first guide wheel group. There is no need to stop the processing of the yarn of the entire drawing machine. By increasing the distance between the first guide wheel group and the second guide wheel group, the continuously processed yarn is temporarily stored, thereby improving the working efficiency of the entire drawing machine. The lifting plate can be repeatedly lifted and lowered to allow the yarn to be evenly wound on the winding roller. BRIEF DESCRIPTION OF THE DRAWINGS

One of the adjacent pair of wire drawing rollers 402 is connected by transmission, and a heating mechanism 6 is arranged at the middle position inside the bin body of the opening and closing bin mechanism 3. The heating mechanism 6 includes a partition 601 located at the middle position inside the installation bin 301. Two sets of infrared heating devices 602 are symmetrically installed on both sides of the partition 601. Baffles 603 are symmetrically installed on the tops of both sides of the partition 601. By controlling the extension and retraction of the electric telescopic rod 303, the side panels 302 of the installation bin 301 can be controlled to be opened or closed. Then, the infrared heating device 602 heats the side panels 302 passing through the partition 601. The yarns on both sides are heated. After the yarns are heated, the four groups of first servo motors 403 are controlled to drive a group of wire drawing rollers 402 connected thereto to rotate through the connecting shafts 404. The speed difference between the two bottom groups of first servo motors 403 and the two top groups of first servo motors 403 is used to stretch the yarns between the four pairs of wire drawing rollers 402. The speeds of the two top groups of first servo motors 403 are always kept the same. The baffle 603 can block impurities generated when the brush 503 cleans the surface of the wire drawing roller 402.

When the electric telescopic rod 303 is controlled to be shortened, the return spring 703 is forced to shorten and store elastic potential energy. At this time, the two groups of drawing rollers 402 in the mounting frame 401 are tightly attached to and clamp the yarn. Then, the first servo motor 403 is controlled to drive the drawing rollers 402 to rotate so that the yarn can be stretched.

A transmission gear 806 meshing with the driven rack 805 and the active rack 807 is symmetrically provided at the top and bottom of the main frame 2 near one end of the connecting frame 501. The first electric push rod 505 is controlled to cooperate with the cross plate 504 to push the connecting frame 501 to move, so that the brush 503 at one end of the moving frame 502 moves from the area originally cleaning half of the surface of the wire drawing roller 402 to the other half, and accompanied by the subsequent rotation of the wire drawing roller 402, the brush 503 automatically cleans the surface of the wire drawing roller 402. During the process, the cross plate 504 slides on the first slide bar 506, and the surface of the wire drawing roller 402 originally cleaned by the brush 5 03 The cleaned half area can continue to stretch the yarn to ensure the processing efficiency of the entire wire drawing machine. During this process, the two sets of active racks 807 at the top and bottom of the connecting frame 501 will drive the transmission gear 806 to rotate, and the transmission gear 806 drives the L-shaped connecting frame 803 to automatically move away from the installation bin 301 through the driven rack 805.

The plate 1002 continues to rise, and when the lifting plate 1002 rests against the bottom of the lifting frame 903 and pushes it to rise together, the lifting frame 903 slides on the two sets of third slide bars 902 during the process, and the continuously processed yarn is temporarily stored by increasing the distance between the first guide wheel group 901 and the second guide wheel group 904. During this process, the operator can operate to replace a new set of rollers to reel in the yarn, and when the lifting frame 903 descends, the limit stopper 906 limits the minimum height to which the lifting frame 903 descends, and the yarn is guided by the first guide wheel group 901, the second guide wheel group 904 and the third guide wheel group 905, so that the yarn is finally reeled in by the winding roller 1003.
[0032] like Figure 3 , Figure 6 and Fig. 20As shown, a wire feeding mechanism 11 is provided at the bottom of the main frame 2 of the present embodiment, and the wire feeding mechanism 11 includes two sets of second bearings 1101 located at the middle position of the bottom of the main frame 2, and the inner rings of the two sets of second bearings 1101 are jointly installed with a wire tube 1102, and the inner top and inner bottom of the wire tube 1102 are both provided with a funnel mouth 1103, and the bottom end of the outer side of the wire tube 1102 is installed with a driven gear 1104, and a driving motor 1105 is installed at the bottom of the main frame 2, and a driving gear 1106 meshing with the driven gear 1104 is installed at the output end of the driving motor 1105, and the driving motor 1105 is controlled to cooperate with the driving gear 1106 and the driven gear 1104 to drive the wire tube 1102 to rotate, and the inner wall of the wire tube 1102 and the funnel mouth 1103 are used to bring the surface fibers of the yarn passing through close to the yarn body, so as to avoid uneven heating of the surface fibers of the yarn when the subsequent infrared heating device 602 heats the yarn.
[0033] like Figure 1-Figure 3 As shown, a tension adjustment mechanism 12 is provided at the top of the main frame 2 of the present embodiment, and the tension adjustment mechanism 12 includes a second electric push rod 1203 located at the middle position of the top of the main frame 2, and an L-shaped top frame 1201 is installed at the output end of the second electric push rod 1203, and the bottom end of the L-shaped top frame 1201 extends to the inner top of the installation bin 301 and is installed with a lifting guide roller 1202. After the yarn is passed around the drawing roller 402, the wire wheel 802 and the outer side of the lifting guide roller 1202 inside the installation bin 301 in sequence, since the yarn is in a relaxed state at this time, it is not conducive to the subsequent heating and stretching of the yarn. The second electric push rod 1203 is controlled to drive the L-shaped top frame 1201 to rise, and then the lifting guide roller 1202 is controlled to rise synchronously, so as to improve the tightness of the yarn inside the installation bin 301 and ensure the heating and stretching effect of the subsequent device on the yarn.
[0034] The working principle of this embodiment is as follows: first, the electric telescopic rod 303 is controlled to extend to open the side panel 302 of the installation bin 301. At this time, a group of wire drawing rollers 402 inside the same installation frame 401 automatically move away from another group of wire drawing rollers 402, and the yarn disk is installed on the rotating disk 13. Then, the yarn head end passes through the wire tube 1102 and enters the bottom of the installation bin 301. Then, the yarn passes through the wire grooves of the two groups of wire wheels 802 at the bottom in turn, and then the yarn passes between the two pairs of wire drawing rollers 402 on the side away from the lifting plate 1002, and then the yarn passes through the wire grooves of the two groups of wire wheels 802 at the top in turn. During the process, the yarn also passes through The yarn passes through the outside of the lifting guide roller 1202, and then passes between the two pairs of drawing rollers 402 near the side of the lifting plate 1002, and then passes through the outlet 14 to the outside of the installation bin 301, and then the yarn passes through a pair of first guide wheel groups 901, a pair of second guide wheel groups 904 and a pair of third guide wheel groups 905 in turn, and is fixed on the outside of a group of winding rollers 1003, and then the L-shaped top frame 1201 is controlled to drive the lifting guide roller 1202 to rise, adjust the tightness of the yarn inside the installation bin 301, and then control the electric telescopic rod 303 to shorten until the side panel 302 and one side of the installation bin 301 are completely closed. At this time, the two groups of drawing rollers 402 inside the same mounting frame 401 are pressed against each other, and the yarn passes between the two groups of drawing rollers 402, and then the infrared heating device 602 is controlled to heat the yarn, and the four groups of first servo motors 403 are controlled to drive the connected drawing rollers 402 to rotate, and the speed difference between the two groups of first servo motors 403 at the bottom and the two groups of first servo motors 403 at the top is used to stretch the yarn between the four pairs of drawing rollers 402. When it is necessary to clean the part of the drawing roller 402 where the yarn is stretched, the infrared heating device 602 is stopped to heat the yarn, and then the electric telescopic rod is controlled 303 is extended, and the strip limit block 708 is no longer on the extrusion connecting plate 702, so that one group of drawing rollers 402 inside the same mounting frame 401 automatically moves away from the other group of drawing rollers 402, and then the extension and retraction of the first electric push rod 505 is controlled to move the brush 503 to the half area of the surface of the drawing roller 402 that needs to be cleaned, and the wire wheel 802 automatically moves the yarn to the other half area of the surface of the drawing roller 402, and then the electric telescopic rod 303 is controlled to shorten back to the original state, and then the yarn is continued to be stretched, and the brush 503 automatically cleans the surface of the drawing roller 402.
