Description

Technical Field

[0001] This utility model relates to the field of DTY processing technology, specifically a thread guide device for a DTY texturing machine. Background Technology

[0002] The DTY texturing machine is a key piece of equipment in the textile industry used to produce drawn textured yarn (DTY). Also known as a drafting false twist texturer or elastic yarn machine, it mainly consists of a raw yarn bobbin holder, drafting rollers, heaters (heat boxes), cooling plates, a false twister, an oiling roller, and a winding mechanism. It is also equipped with a yarn breakage detector, a yarn cutter, a yarn suction device, and network nozzles. Based on the different arrangements of the heat boxes, cooling plates, and winding frames, it is mainly divided into three types: M-type, V-type, and T-type. The raw yarn is fed in by the first drafting roller and first increases its thermoplasticity and stretches in the first heat box. The cooling plate fixes the stretching deformation of the yarn bundle, reduces its thermoplasticity, and obtains twist. When exiting from the false twister, it rotates to untwist and exits through the second drafting roller to complete the stretching deformation process. Afterward, it enters the second heat box for supplemental heat setting (this step is not required for high-elasticity yarns). Finally, it is oiled by the oiling roller and wound into a bobbin.

[0003] During the processing of welding wire coils, the welding wire needs to be continuously pulled. Because the welding wire coils are relatively curved, the welding wires often become entangled with each other during the pulling process, which hinders the mechanical pulling of the welding wires and affects the normal processing of the welding wires.

[0004] To address the aforementioned problems, existing technologies offer a solution. For example, patent publication number CN219113220U provides a silver solder wire guiding device. This device features symmetrically arranged semicircular blocks within a guide cylinder, compressed by springs. A through-slot is formed on each semicircular block, allowing the solder wire to be held within the slot. The compression of the spring automatically adjusts the size of the through-slot to accommodate solder wires of different sizes, preventing tangling. A lifting assembly allows for manual adjustment of the guide cylinder's height according to work requirements. A knob slot and knob design facilitate easy rotation of the lead screw without the knob protruding from the base plate and causing injury. A bolt slot ensures that the bolts, once the base plate is secured, do not protrude and cause injury. This solution effectively addresses the problem of welding wires often tangling during traction, hindering mechanical traction and affecting normal processing. Furthermore, it addresses the issue that the guiding mechanism often requires position adjustments based on usage requirements. Existing devices typically use a roller to guide the wire path, but the wire path is taut during transport. When transport stops, it loosens due to loss of tension. This sudden shift from taut to slack can easily cause the wire path to detach from the roller, preventing proper guidance for the next operation.

[0005] Therefore, a silk path guiding device for a DTY texturing machine is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a thread guide device for a DTY texturing machine to solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A yarn guide device for a DTY texturing machine includes a base, an unwinding frame, and a rewinding frame. It also includes a servo motor, an adjustment mechanism, a fixed base, a rack, a drive mechanism, and a guide wheel assembly. The servo motor is connected to the base, the adjustment mechanism is connected to the servo motor, the fixed base and the rack are both connected to the adjustment mechanism, the drive mechanism is connected to the rack, and the guide wheels are connected to the drive mechanism. When the servo motor starts, the adjustment mechanism adjusts the height of the fixed base and the guide wheel assembly. When the fixed base is height adjusted, the rack moves synchronously and the drive mechanism controls the guide wheel assembly to move towards each other to improve the fit with the yarn.

[0008] Preferably, the adjusting mechanism includes a fixed sleeve, a limiting block, a moving sleeve, a screw, a spur gear, and a toothed belt. The fixed sleeve is connected to the base, the limiting block is connected to the fixed sleeve, the moving sleeve is connected to the limiting block, the screw is connected to the moving sleeve, the spur gear is connected to the screw, and the toothed belt engages with the spur gear.

[0009] Preferably, the fixed sleeve has a limiting groove inside, and two limiting grooves are symmetrically arranged around the center line of the fixed sleeve. The limiting block is installed in the limiting groove, and the bottom end of the limiting block is flush with the bottom end of the moving sleeve.

[0010] Preferably, multiple sets of the unwinding group, the winding frame, the fixing sleeve, and the spur gear are provided, and the unwinding frame and the winding frame are symmetrically arranged with respect to the center line of the fixing sleeve.

[0011] Optionally, when guiding the silk path, the conveying of the silk path can be left unrestricted, allowing it to be unobstructed above or below. The silk path can also be conveyed in extremely confined spaces. If the guide rollers are not sealed, the silk path may easily detach from the guide rollers when changing from a taut to a slack state after winding and replacing the take-up rollers. This requires manual repositioning of the silk path onto the guide rollers, reducing the efficiency of silk path processing. Therefore, it is necessary to seal the guide rollers during the guiding process of silk path processing, ensuring the silk path is conveyed within a confined space. This prevents the silk path from detaching from the guide rollers, thereby improving the efficiency of silk path processing.

[0012] Preferably, the drive mechanism includes a connecting gear, a lead screw, and a threaded block. The connecting gear engages with a rack, the lead screw is connected to the connecting gear, the threaded block is connected to the lead screw, and the guide wheel assembly is connected to the threaded block.

[0013] Preferably, the lead screw is provided with multiple sets of positive and negative thread grooves, the number of which is the same as the number of fixed seats, and two thread blocks are symmetrically arranged on each set of positive and negative thread grooves.

[0014] Preferably, the guide wheel assembly includes a concave wheel and a cam, the concave wheel is provided with a concave portion, the cam is provided with a convex portion, both the concave portion and the convex portion are arc-shaped, and the concave portion and the convex portion are matched.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By controlling the rise of the fixed seat, the wire is kept taut during winding. At the same time, the clamping of the wire by the concave wheel and cam prevents the wire from moving randomly from a taut to a slack state when winding stops. This prevents the wire from disengaging from the guide wheel assembly, thus ensuring the stability of the wire winding and providing better guidance during winding. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4A yarn guide device for a DTY texturing machine includes a base 1, an unwinding frame 2, and a winding frame 3. It also includes a servo motor 4, an adjusting mechanism 5, a fixed base 6, a rack 7, a drive mechanism 8, and a guide wheel assembly 9. The servo motor 4 is connected to the base 1 and is fixedly mounted on one side of the base 1. This configuration improves the stability of the device's operation. The adjusting mechanism 5 is connected to the servo motor 4. The fixed base 6 and the rack 7 are both connected to the adjusting mechanism 5. The drive mechanism 8 is connected to the rack 7. The guide wheel assembly 9 is connected to the drive mechanism 8. The guide wheel assembly 9 includes a concave wheel 91 and a cam 92. The concave wheel 91 has a recess 91. 1. The cam 92 is provided with a protrusion 921 and a concave portion 911. Both the protrusion 921 and the concave portion 911 are arc-shaped. The concave portion 911 matches the protrusion 921. Through the above arrangement, the cam 92 and the concave wheel 91 squeeze the wire together, thereby preventing the wire from becoming loose during winding and guiding, and also preventing the wire from moving up and down during conveying, thus ensuring the stability of the wire during guidance. When the servo motor 4 starts, the adjustment structure adjusts the height value of the fixed seat 6 and the guide wheel group 9. When the fixed seat 6 is adjusted in height, the rack 7 moves synchronously and the drive mechanism 8 controls the guide wheel group 9 to move towards each other to improve the fit with the wire.

[0020] As one embodiment of this utility model, refer to Figure 2 and Figure 3The adjusting mechanism 5 includes a fixed sleeve 51, a limiting block 52, a moving sleeve 53, a screw 54, a spur gear 55, and a toothed belt 56. The fixed sleeve 51 is connected to the base 1 and is fixedly installed on the top of the base 1. The limiting block 52 is connected to the fixed sleeve 51, and the moving sleeve 53 is connected to the limiting block 52. The limiting block 52 is movably connected to the fixed sleeve 51, while the limiting block 52 is fixedly connected to the moving sleeve 53. Through the above arrangement, the moving sleeve 53 is positioned on the fixed sleeve 51 via the limiting block 52. 1. The screw 54 moves internally and is connected to the moving sleeve 53. The screw 54 and the moving sleeve 53 are screwed together. At this time, the moving sleeve 53 is equivalent to a large screw block, so that when the screw 54 rotates, it drives the moving sleeve 53 to rise and fall. The spur gear 55 is connected to the screw 54 and is fixedly connected to the screw 54. Through the above arrangement, the rotation of the spur gear 55 realizes the rotation of the screw 54. The toothed belt 56 cooperates with the spur gear 55, and the toothed belt 56 meshes with the spur gear 55. Through the above arrangement, the rotation of the screw 54 is realized. The synchronous rotation of multiple spur gears 55 is achieved. A limiting groove 57 is provided inside the fixed sleeve 51. Two limiting grooves 57 are symmetrically arranged around the center line of the fixed sleeve 51. This arrangement ensures stable movement of the limiting block 52. The limiting block 52 prevents the moving sleeve 53 from colliding with the fixed sleeve 51 due to friction from the screw 54 during lifting and lowering. It also prevents torque transmission caused by meshing force loss or assembly gaps in the moving sleeve 53. The limiting block 52 is installed within the limiting groove 57, providing space for its movement. The bottom end of the limiting block 52 is flush with the bottom end of the moving sleeve 53. Multiple sets of unwinding frame 2, winding frame 3, fixed sleeve 51, and spur gears 55 are provided. The unwinding frame 2 and winding frame 3 are symmetrically arranged around the center line of the fixed sleeve 51. This arrangement ensures consistent movement distance of the wire path and maintains consistent wire path inclination values ​​at both ends of the base 1 when the base 1 rises to lift the wire path, thus ensuring stable wire path transport.

[0021] As one embodiment of this utility model, refer to Figure 4The drive mechanism 8 includes a connecting gear 81, a lead screw 82, and a threaded block 83. The connecting gear 81 meshes with a rack 7, and the lead screw 82 is connected to and fixedly connected to the connecting gear 81. This arrangement ensures that the connecting gear 81 and the lead screw 82 rotate synchronously. The threaded block 83 is connected to and screwed onto the lead screw 82. This arrangement allows the rotation of the lead screw 82 to control the horizontal movement of the threaded block 83. The guide wheel assembly 9 is connected to the threaded block 83. Next, both the concave wheel 91 and the cam 92 are fixedly connected to the threaded block 83. Through the above arrangement, the movement of the threaded block 83 drives the guide wheel group 9 to move synchronously. The lead screw 82 is provided with multiple sets of positive and negative thread grooves 821. The number of positive and negative thread grooves 821 is the same as the number of fixed seats 6. Two threaded blocks 83 are symmetrically arranged on each set of positive and negative thread grooves 821. Through the above arrangement, the synchronous movement of multiple sets of guide wheel groups 9 is ensured, and the guidance of multiple sets of thread paths is realized, thereby improving the efficiency of thread path processing.

[0022] Working principle: When in use, the user places the yarn roll on the unwinding frame 2, then places the empty take-up roller on the take-up frame 3, then passes one end of the yarn through the guide wheel assembly 9 and connects one end of the yarn to the take-up frame 3, and then controls the servo motor 4 to start. When the servo motor 4 starts, it drives a spur gear 55 to rotate. When the spur gear 55 rotates, it drives the toothed belt 56 to rotate. When the toothed belt 56 rotates, it drives other spur gears 55 to rotate. When the spur gear 55 rotates, it drives the screw 54 to rotate. When the screw 54 rotates, it drives the moving sleeve 53 to rise within the fixed sleeve 51. When the moving sleeve 53 rises, it drives the limiting block 52 to move within the limiting groove 57. At the same time, it drives the fixed seat 6 to rise. During the rising process, the fixed seat 6 gradually tightens the silk road. When the moving sleeve 53 rises, it drives the connecting gear 81 to rise as well. The rising connecting gear 81 meshes with the rack 7, thereby controlling the rotation of the connecting gear 81. The rotation of the connecting gear 81 drives the lead screw 82 to rotate. When the lead screw 82 rotates, it drives each set of threaded blocks 83 to move in opposite directions through the positive and negative threaded grooves 821. When the threaded blocks 83 move, they drive the concave wheel 91 and the cam 92 to move in opposite directions, thereby controlling the convex part 921 to enter the concave part 911, achieving the clamping of the thread path and preventing loosening during conveying. Although the embodiments of this utility model have been described in detail with reference to the accompanying drawings, those skilled in the art can make changes, modifications, substitutions, and variations to these embodiments without departing from the principles and spirit of this utility model. The appended claims and their equivalents define the scope of this utility model.
