Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn guide for polymer fiber production. Background Art

[0002] The traditional fixed yarn guide for imitation cotton shaped fibers is only used for guiding. Therefore, when the yarn breaks during use, it cannot be detected and there is no alarm device. As a result, the yarn produced after the yarn breaks cannot be wound, resulting in a waste of resources.

[0003] Chinese patent CN213622681U discloses a ceramic wire guide for flame-retardant low-elastic fiber yarn. A wire plate and a slot are arranged inside a mounting seat. When the fiber yarn breaks, the wire plate contacts the slot, connecting the alarm circuit and reminding the operator to handle it in time.

[0004] However, this device can only be used to guide a single fiber thread, and it can slide down to trigger an alarm when the fiber thread breaks. The warping machine needs to complete several warps at a time. When this device is used, the breakage of a single fiber will not trigger an alarm. In addition, the breakage of a few fibers will not only fail to attract the attention of the operator, but can also be easily pulled away by other fibers, affecting subsequent textile use. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a yarn guide for polymer fiber production, which solves the problem that in the process of transmitting a large number of fibers as a whole, it is difficult for an operator to notice that very few fibers are broken.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a yarn guide for polymer fiber production, including a base assembly and yarn guide wheel assemblies arranged on both sides thereof, the base assembly can adjust the distance between two sets of yarn guide wheel assemblies, a pressure regulating wheel assembly is installed in the middle of the top of the base assembly to press down the polymer fibers overlapped between the two sets of yarn guide wheel assemblies, a broken yarn suction structure is installed on the yarn guide wheel assembly at the yarn feeding end to suck the broken fibers into the interior, and the broken yarn suction structure is provided with an observation structure for observing the suction situation of the broken fibers.

[0007] Preferably, the broken wire suction structure includes a mounting frame installed on the top of the front and rear sides of the wire guide wheel assembly, and an air suction hood is fixedly connected between the two mounting frames, and a transparent observation tube is threadedly connected to the front side of the front mounting frame through a mounting tube, and an air duct is installed at the front end of the transparent observation tube through a threaded cover, and the other end of the air duct is connected to a fan.

[0008] Preferably, the observation structure includes the above-mentioned transparent observation tube and also includes a lamp bead that penetrates and is fixed on the bottom of the installation tube.

[0009] Preferably, a filter is crimped between the threaded cover and the front end of the transparent observation tube.

[0010] Preferably, the base assembly includes a base and a bidirectional screw rod connected thereto for horizontal rotation, and a first servo motor for driving the bidirectional screw rod for rotation is fixedly connected to the right side of the base.

[0011] Preferably, the guide wire wheel assembly includes a support frame and a support wheel rotatably connected to the top thereof, and the support frames on both sides are respectively threadedly sleeved on two opposite threads of the bidirectional screw rod.

[0012] Preferably, the pressure regulating wheel assembly includes a fixed seat fixedly connected to the center of gravity of the inner side of the base, the front and rear sides of the fixed seat are longitudinally slidably connected to the lifting plates through guide rails, and the pressure wheel is rotatably connected between the top ends of the two sets of lifting plates.

[0015] Beneficial Effects

[0016] The utility model provides a yarn guide for polymer fiber production. Compared with the prior art, it has the following beneficial effects:

[0017] 1. The yarn guide for polymer fiber production is provided with a broken yarn suction structure, which can use wind power to suck out the broken fiber yarns during the yarn guiding process. On the one hand, it can separate and concentrate the broken yarns to avoid the broken yarns being mixed with other fibers and affecting the subsequent use effect. On the other hand, the transparent observation tube is used with a single-point lighting effect to make it easier for the staff to find the broken yarns when they swing in the transparent observation tube. The filter can also prevent the broken yarns from being sucked away and discharged by the fan, which is convenient for regular processing of the collected broken yarns.

[0018] 2. The yarn guide for polymer fiber production can adjust the spacing between the yarn guide wheel assemblies on both sides by using the base assembly to adapt to different yarn guide spacing requirements, and the tension of the polymer fiber can be adjusted by using the middle pressure regulating wheel assembly to press down the polymer fiber, so as to achieve better pulling and winding.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides two technical solutions:

[0026] Figure 1-3 The first embodiment is shown: a yarn guide for polymer fiber production, including a base assembly 1 and a yarn guide wheel assembly 2 arranged on both sides thereof, the yarn guide wheel assembly 2 can transmit a number of fiber yarns at the same time, the base assembly 1 can adjust the distance between the two sets of yarn guide wheel assemblies 2, a pressure regulating wheel assembly 3 is installed in the middle of the top of the base assembly 1 to press down the polymer fibers overlapped between the two sets of yarn guide wheel assemblies 2, a broken yarn suction structure 4 is installed on the yarn guide wheel assembly 2 at the yarn feeding end to suck the broken fibers into the inside, and the broken yarn suction structure 4 is provided with an observation structure for observing the suction situation of the broken fibers.

[0027] The broken wire suction structure 4 includes a mounting frame 41 installed on the top of the front and rear sides of the guide wire wheel assembly 2, and an air suction hood 42 is fixedly connected between the two mounting frames 41, and a transparent observation tube 43 is threadedly connected to the front side of the front mounting frame 41 through a mounting tube, and an air duct 44 is installed at the front end of the transparent observation tube 43 through a threaded cover, and a filter screen 47 is crimped between the threaded cover and the front end of the transparent observation tube 43, and a fan 45 is connected to the other end of the air duct 44, and the broken fiber blocked by the filter screen 47 can be taken out by unscrewing the threaded cover.

[0028] The observation structure includes the transparent observation tube 43 and also includes a lamp bead 46 that penetrates and is fixed at the bottom of the installation tube.

[0029] By setting up the broken wire suction structure 4, the broken fiber wires in the wire guiding process can be sucked out by wind force. On the one hand, the broken wires can be separated and concentrated to avoid the broken wires being mixed with other fibers and affecting the subsequent use effect. On the other hand, the transparent observation tube 43 is used in combination with the single-point lighting effect to make it easier for the staff to find the broken wires when they swing in the transparent observation tube 43. The filter 47 can also prevent the broken wires from being sucked away and discharged by the fan 45, which is convenient for regular processing of the collected broken wires.

[0030] Figure 2 and Figure 4 A second embodiment is shown, which mainly differs from the first embodiment in that the base assembly 1 includes a base 11 and a bidirectional screw rod 12 connected thereto for horizontal rotation therein, and a first servo motor 13 is fixedly connected to the right side of the base 11 to drive the bidirectional screw rod 12 to rotate.

[0031] The guide wheel assembly 2 includes a support frame 21 and a support wheel 22 rotatably connected to the top thereof, and the support frames 21 on both sides are respectively threadedly sleeved on two opposite threads of the bidirectional screw rod 12 .

[0032] The pressure regulating wheel assembly 3 includes a fixed seat 31 fixedly connected to the center of gravity of the inner side of the base 11, and the front and rear sides of the fixed seat 31 are longitudinally slidably connected with the lifting plate 33 through the guide rail 32, and the pressure wheel 34 is rotatably connected between the top ends of the two groups of lifting plates 33, and a rotating shaft 35 is rotatably connected through the middle of the fixed seat 31, and gears 36 are fixedly connected at both ends of the rotating shaft 35 and located on the inner side of the lifting plate 33, and a vertical groove adapted to the gear 36 is opened on the inner side of the lifting plate 33, and a tooth groove 37 meshing with the gear 36 is opened on one side of the vertical groove, and a second servo motor 38 is fixedly connected to the front side of the fixed seat 31 through the base, and the output shaft of the second servo motor 38 is fixedly connected to one end of the rotating shaft 35 through a torque sensor 39.

[0033] The base assembly 1 can be used to adjust the spacing between the wire guide wheel assemblies 2 on both sides to adapt to different wire guide spacing requirements, and the middle pressure regulating wheel assembly 3 is used to press down the polymer fiber to adjust the tension of the polymer fiber for better pulling and winding. The second servo motor 38 that provides driving force uses a torque sensor 39 to indirectly output the driving force, which is convenient for directly outputting the pressure value, and the tension can be intuitively obtained, which is convenient for better control of the second servo motor 38.

[0034] The two servo motors and the torque sensor 39 are both connected to the control host through wires.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0036] When in use, the fiber filaments are placed on the supporting wheels 22 of the two sets of guide wheel assemblies 2, and are conveyed around the bottom of the pressure wheel 34 of the pressure regulating wheel assembly 3; if any fiber is broken during the conveying process, it loses tension and will be sucked into the suction hood 42 under the wind force of the fan 45, and then float in the transparent observation tube 43. For shorter broken fibers, they can be directly and completely sucked in so that they are blocked and collected by the filter 47. During the working process, it can be judged whether it is necessary to open the threaded cover to remove the broken fibers by observing whether there are broken fibers or the number of broken fibers in the transparent observation tube 43.

[0037] When the distance between the guide wheel assemblies 2 needs to be adjusted, the first servo motor 13 is controlled to drive the bidirectional screw rod 12 to rotate, thereby driving the two sets of guide wheel assemblies 2 to move closer or farther away to the required distance.

[0038] When the tensioning force needs to be adjusted, the second servo motor 38 is controlled to drive the rotating shaft 35 to rotate through the torque sensor 39, and the gear 36 is used to drive the lifting plate 33 and the pressure wheel 34 to rise and fall, thereby controlling the pressure on the fiber. The value output by the torque sensor 39 is compared with the value when there is no fiber transmission at the beginning, and the pressure value on the fiber can be obtained.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
