Description

Technical Field

[0001] The present invention belongs to the technical field of temperature-controlled spinning boxes, and more specifically, particularly relates to an intelligent temperature-controlled spinning box device for DTY yarn production. Background Art

[0002] In the field of DTY yarn production, the market's requirements for product quality and production efficiency are increasing day by day. From the perspective of product quality, with the diversified development of the textile industry, DTY yarn is widely used in many fields such as high-end clothing fabrics, aerospace fabrics, and medical supplies. The demand for the quality characteristics of DTY yarn varies significantly in different fields.

[0003] Currently, the existing temperature-controlled spinning boxes have at least the following technical problems: First, in the production process of DTY yarn, the winding link of traditional spinning equipment has always been a key factor restricting production efficiency. In the early spinning equipment, the design of single filament bundle collecting rollers or a small number of filament bundle collecting rollers was mostly adopted. The process of winding the pre-oriented yarn into a yarn cake was slow. Taking the traditional single filament bundle collecting roller equipment as an example, the time required to wind each yarn cake was relatively long. Under the demand of large-scale production, this low-efficiency winding method made it difficult to improve the overall output.

[0004] Second, in the production process of DTY yarn, the static electricity problem has always been a key factor affecting product quality and production stability. The pre-oriented yarn is extremely easy to generate static electricity during the production process, while the traditional device lacks effective means to eliminate static electricity. The accumulation of static electricity will cause the pre-oriented yarn to adsorb and entangle with each other. When passing through the winding mechanism, the filament bundle cannot be smoothly wound. The adhesion between the filament bundles will cause the yarn cake to be unevenly formed, with local density inconsistencies, seriously affecting the quality of the yarn cake and increasing the defective rate. Static electricity will also adsorb impurities such as dust in the air to contaminate the filament bundle, reducing the purity of DTY yarn and affecting its subsequent application in high-end textile products. In the production of high-end clothing fabrics, DTY yarn containing impurities will cause defects in the fabric and reduce the product quality. Summary of the Invention

Specific Embodiments

[0016] The following further describes in detail the embodiments of the present invention with reference to the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0017] Please refer to Figures 1-9, the present invention provides an intelligent temperature-controlled spinning box device for DTY yarn production, including a spinning box body 11, on which a collection bucket support 13 is fixedly installed, and on the collection bucket support 13, a protective shell 12 is fixedly installed. The protective shell 12 is used to prevent dust from entering the raw materials when the spinning box discharges and bundles the filaments. On both protective shells 12, a screw extruder 14 is fixedly installed. The screw extruder 14 is provided with a screw extrusion rod and three wire outlets. The raw materials in the spinning box enter the bundling mechanism through the extrusion of the screw extrusion rod from the wire outlets. Inside the protective shell 12, a third spur gear 28 is provided. The circumferential surface of the third spur gear 28 is provided with annular gears, and three fourth spur gears 29 are meshed with the circumferential surface of the third spur gear 28. A reciprocating screw rod 35 is fixedly installed on the third spur gear 28. Two groups of intersecting and spiral-shaped chutes that are connected at both ends are opened on the reciprocating screw rod 35. A shuttle-shaped slider 37 is slidably installed in the chute opened on the reciprocating screw rod 35. The shuttle-shaped slider 37 being shuttle-shaped is more conducive to moving back and forth in the chute opened on the reciprocating screw rod 35.

[0018] Inside the protective shell 12, a bundling mechanism is installed. The bundling mechanism can improve the efficiency of winding the partially oriented yarn into a yarn cake when the spinning box discharges the filaments, and ensure the uniformity of the wound yarn cake. A tension adjusting mechanism is provided on the reciprocating screw rod 35. The tension adjusting mechanism is used to keep the partially oriented yarn at a fixed tension when the movable seat 36 reciprocates, and at the same time eliminate a part of the static electricity of the partially oriented yarn.

[0019] In this embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 7As shown in the figure, the winding mechanism includes a triangular fixing plate 19. A second transmission rod 27 is rotatably installed through the triangular fixing plate 19. A fixed platform 43 is fixedly installed on the triangular fixing plate 19. The triangular fixing plate 19 is rotatably installed with a third flat gear 28. The third flat gear 28 and the second transmission rod 27 are fixedly connected. The triangular fixing plate 19 is a triangular plate. Every three fourth flat gears 29 are rotatably installed at the three corners of the triangular fixing plate 19. A third transmission rod 31 is fixedly installed on each fourth flat gear 29. A yarn bundle collecting roller 32 for winding and collecting pre-oriented yarn is fixedly installed through the third transmission rod 31. A movable seat 36 is installed on the reciprocating lead screw 35. A rotating shaft 42 is rotatably installed on the movable seat 36. The rotating shaft 42 and the shuttle-shaped slider 37 are fixedly installed. A wire tightening device 45 is fixedly installed on the movable seat 36. The wire tightening device 45 is used for fine-tuning the tension of the yarn bundle. A guiding and limiting device 33 is fixedly installed on the movable seat 36. The guiding and limiting device 33 is provided with three apertures for limiting. A limiting rod 34 is fixedly installed on the fixed platform 43. The limiting rod 34 passes through the limiting holes provided on the guiding and limiting device 33 to limit the movable seat 36, so that the movable seat 36 can maintain a horizontal reciprocating motion at an angle on the reciprocating lead screw 35. When collecting pre-oriented yarn, the pre-oriented yarn is connected to the wire tightening device 45 through three wire outlets provided on the collecting bucket bracket 13, and then wound from the wire tightening device 45 onto the yarn bundle collecting roller 32. The third flat gear 28 drives the reciprocating lead screw 35 to rotate. The movable seat 36 is limited by the limiting rod 34 and the guiding and limiting device 33. The shuttle-shaped slider 37 in the chute provided on the reciprocating lead screw 35 drives the movable seat 36 to perform a horizontal reciprocating motion. This kind of motion can enable the three wire tightening devices 45 installed on the movable seat 36 to evenly wind the pre-oriented yarn onto the yarn bundle collecting roller 32.

[0020] In this embodiment, as Figure 4 , Figure 6 , Figure 8 and Figure 9As shown in the figure, the tension adjusting mechanism includes a second positioning bracket 44. The second positioning bracket 44 and the guiding and limiting device 33 are fixedly installed. A second rotating rod 39 is rotatably installed on the second positioning bracket 44. A first rotating rod 38 is rotatably installed on the second rotating rod 39. Thread grooves through which the pre-oriented yarn can pass are provided inside the second rotating rod 39 and the first rotating rod 38. Wire guiding holes 46 are provided on both the second rotating rod 39 and the first rotating rod 38. The wire guiding hole 46 provided on the first rotating rod 38 is used to guide the filament bundle from the spinneret into the thread groove. The wire guiding hole 46 provided on the second rotating rod 39 is used to guide the filament bundle passing through the thread groove to the wire tightening device 45. A number of guiding pulleys and a passive static eliminator are provided in the thread groove. The passive static eliminator can eliminate the static electricity of the pre-oriented yarn passing through the thread grooves provided inside the first rotating rod 38 and the second rotating rod 39. Flaps are provided on the sides of the first rotating rod 38 and the second rotating rod 39, which is convenient for the staff to guide the filament bundle during work. The connection between the first rotating rod 38 and the second rotating rod 39 has a certain angle, and this angle can prevent the tension adjusting mechanism from interfering with the wire bundle and the spool. A first positioning bracket 41 is rotatably installed on the first rotating rod 38. When the guiding and limiting device 33 moves horizontally, it drives the first rotating rod 38 and the second rotating rod 39 to rotate at a certain angle. When collecting the pre-oriented yarn, when the filament bundle passes through the thread grooves inside the first rotating rod 38 and the second rotating rod 39, the passive static eliminator in the thread groove eliminates the static electricity generated by the passing filament bundle during the production process. And due to the rotational connection between the first rotating rod 38 and the second rotating rod 39, the pre-oriented yarn in the thread groove can maintain the same tension no matter what position the movable seat 36 moves to.

[0021] In this embodiment, as Figure 1 , Figure 2 , and Figure 4 shown, a first helical gear 21 is provided between two collecting barrel brackets 13. The servo motor is connected to the first helical gear 21 through a fixed output shaft. Helical teeth are provided on the circumferential surface of the first helical gear 21. Two second helical gears 22 are meshed with the circumferential surface of the first helical gear 21. Each second helical gear 22 is fixedly installed with a first transmission rod 23. A first spur gear 25 is fixedly installed through the first transmission rod 23. Teeth are provided on the circumferential surface of the first spur gear 25. A gear synchronous belt 24 is meshed with the circumferential surface of the first spur gear 25. A second spur gear 26 is meshed inside the gear synchronous belt 24. The second spur gear 26 and the second transmission rod 27 are fixedly installed through. The second transmission rod 27 and the reciprocating lead screw 35 are fixedly installed. During work, the servo motor transmits the power to two directions through the first helical gear 21, and further drives the two groups of wire winding mechanisms on both sides of the spinning box body 11 to operate.

[0022] Working principle: First step, when the raw materials inside the spinning box reach the specified temperature, the screw extrusion rod inside the screw extruder 14 extrudes the raw materials from the wire outlet. At this time, the servo motor starts. The staff needs to pass the fiber bundle through the wire grooves inside the first rotating support rod 38 and the second rotating support rod 39 in sequence, and then through the wire tightener 45, and pre-wind it on the fiber bundle collecting roller 32. After the preparation work is completed, the servo motor drives the first bevel gear 21 to start rotating through the fixed output shaft.

[0023] Second step, the circumferential surfaces of the first bevel gear 21 and the second bevel gear 22 are meshed with each other, and the second bevel gear 22 and the first spur gear 25 are both fixedly connected to the first transmission rod 23. Therefore, when the first bevel gear 21 rotates, it will drive the first transmission rod 23 and the first spur gear 25 to rotate synchronously. The first spur gear 25 is meshed with the gear synchronous belt 24, and the gear synchronous belt 24 is meshed with the second spur gear 26. This transmission relationship enables the second spur gear 26 to drive the second transmission rod 27 to rotate synchronously. The second transmission rod 27 is connected to the third spur gear 28, and then drives the third spur gear 28 to rotate. Three fourth spur gears 29 are meshed on the circumferential surface of the third spur gear 28. These three fourth spur gears 29 are all rotatably installed at the three corners of the triangular fixing plate 19. Therefore, when the third spur gear 28 rotates, it will cause the three fourth spur gears 29 arranged on the triangular fixing plate 19 to rotate synchronously. A third transmission rod 31 is fixedly installed on each fourth spur gear 29. The fiber bundle collecting roller 32 is fixedly installed through the third transmission rod 31. When the fourth spur gear 29 rotates, it drives the fiber bundle collecting roller 32 to rotate, and the fiber bundle begins to wind around the fiber bundle collecting roller 32.

[0024] Third step, while the third spur gear 28 rotates, it also drives the reciprocating lead screw 35 fixedly installed with it to rotate. Two groups of intersecting and spiral-shaped chutes connected at both ends are provided on the reciprocating lead screw 35. The shuttle-shaped slider 37 is installed in the chute. When the shuttle-shaped slider 37 moves through the chute provided on the reciprocating lead screw 35, due to the limiting effect of the limiting rod 34 and the cooperation between the guiding and limiting device 33 and the limiting rod 34, the movable seat 36 installed on the reciprocating lead screw 35 can only move horizontally back and forth. When the fiber bundle passes through the wire tightener 45 on the movable seat 36, the wire tightener 45 will finely adjust the tension of the fiber bundle. During the horizontal reciprocating movement of the movable seat 36, the fiber bundle will wind back and forth and evenly around the fiber bundle collecting roller 32, and finally form a cake of fibers.

[0025] The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
