Description

Technical Field

[0001] This utility model belongs to the technical field of false twisting machines, specifically relating to a double-dragon belt false twister transmission device for a false twisting machine. Background Technology

[0002] The false twister is a key actuator in the false twist texturing machine for chemical fibers. It is generally distributed at the A-side station and the B-side station. When using a belt drive to realize the power input of the false twister, a single belt drive structure is often adopted. That is, the false twisters at the A-side station and the B-side station share the same transmission system, thereby driving the false twisters on both sides to run synchronously.

[0003] However, in the above transmission method, the transmission parameters of the false twisters on the A side and the B side are coupled together, and they can only run at the same speed. This makes it difficult to meet the needs of producing different products on both sides of the equipment at the same time, resulting in poor adaptability of the whole machine to multi-variety, small-batch production. At the same time, although the double-belt structure can independently drive the false twisters on both sides to achieve the production of multiple products, the belt is prone to problems such as unstable deflection, deviation, slippage, and inconvenient tension adjustment during long-distance operation, which affects the stability of the power input of the false twisters and the overall operation of the machine.

[0004] Therefore, there is an urgent need for a double-draft false twister transmission device for false twisting machines that can achieve independent transmission between the A-side and B-side workstations and can effectively guide, limit, and adjust the tension of the transmission belt. Utility Model Content

[0036] Existing false-twist texturing machines are conventional chemical fiber tow processing equipment. Their overall structure, arranged sequentially along the yarn's running direction, includes functional areas for heating, cooling, false twisting, drafting, and winding. The false-twist area is used to false-twist the yarn tow using false-twist devices. Furthermore, the false-twist texturing machine typically includes a head frame and a tail frame positioned opposite each other along the machine's length, forming a false-twist working area. Multiple sets of false-twist devices are arranged within this working area, extending from the head frame to the tail frame, to meet the needs of multi-spindle processing. The false-twist device, as the actuating component of the false-twist texturing machine, requires continuous power input via an external transmission mechanism to drive the device discs at high speed, thereby achieving the false-twist processing of the yarn tow. The winding section of the false-twist texturing machine is generally located on the yarn exit side of the false-twist working area, used to wind the false-twist processed yarn tows into finished yarn bobbins.

[0037] Furthermore, in actual equipment layout, the false twisters in the false twisting work area are usually arranged in two opposing rows, forming station A and station B respectively, with an empty area between the two stations. The false twisters on station A and station B correspond to their respective yarn paths and winding sections. The false-twisted yarn bundles are transported to the corresponding winding section for winding along the predetermined yarn path at their respective stations. Therefore, the two stations have both spatial independence and the practical need to independently adjust process parameters during production.

[0038] Based on this, the double-dragon belt type false twister transmission device for the false twisting texturer provided in this application is arranged in the false twisting working area. Through two transmission units respectively set for the A-side workstation and the B-side workstation, the false twisters in the two-side workstation are independently powered, so that the false twisting texturer can adapt to the use requirements of processing different varieties of products on both sides at the same time.

[0039] The technical solution of this application will now be described in detail with reference to the accompanying drawings.

[0040] A double-dragon belt false twister transmission device for a false twist texturing machine, such as Figures 1 to 2As shown, the false-twist texturing machine includes a front frame 1 and a rear frame 2. The area between the front frame 1 and the rear frame 2 is the false-twist working area of ​​the false-twist texturing machine. Within the false-twist working area, there are two rows of false-twist units 3 located at workstations A and B respectively. Each false-twist unit includes an independent power input wheel 301. The empty area between workstations A and B is configured as a rotation zone 4. The false-twist texturing machine also includes a frame located within the false-twist working area. The frame includes several wall panels arranged at intervals. The first wall panel on the side near the front frame 1 is configured as the front wall panel 101, and the first wall panel on the side near the rear frame 2 is configured as the rear wall panel 201. The front wall panel 101 and the rear wall panel 201 are located at the two ends of the false twist working area, respectively. The wall panel between the front wall panel 101 and the rear wall panel 201 is configured as the intermediate wall panel 5, and there are several intermediate wall panels 5. The frame also includes other frame components. The false twister 3 is supported and erected in the false twist working area through the cooperation of the other frame components and each wall panel.

[0041] It should be noted that the arrangement of the frame, the front frame 1, the rear frame 2, the false twister 3, and the turning zone 4 are all common structural arrangements in existing false twist forming machines. The A-side station and the B-side station are also common expressions in the field of existing false twist forming machines for ease of description, which can be known by those skilled in the art through existing published documents. In addition, this application improves the transmission method of the false twister in the false twist forming machine. Therefore, the double-dragon belt false twister transmission device of this application includes: two transmission units 6 with the same structure, which are used to provide power transmission for each false twister in the A-side station and the B-side station, respectively.

[0042] Among them, such as Figure 3 As shown, each transmission unit 6 includes: a drive motor 601, a drive pulley 604, a driven pulley 602, and two sets of tensioning components 7 with the same structure. The two sets of tensioning components 7 are respectively set in the front frame 1 and the rear frame 2.

[0043] The driving pulley 604 and the driven pulley 602 are respectively mounted on two sets of tensioning components 7. The driving pulley 604 is mounted on one set of tensioning components 7 via a motor mounting plate 603, and the driven pulley 602 is mounted on the other set of tensioning components 7 via a driven pulley mounting plate 605. In addition, the driving motor 601 is located below the motor mounting plate 603, and the output shaft of the driving motor 601 passes through the motor mounting plate 603 and extends to the top of the motor mounting plate 603. The driving pulley 604 is horizontally mounted above the motor mounting plate 603 via the output shaft of the driving motor 601. The driven pulley 602 is horizontally mounted above the driven pulley mounting plate 605 via a rotating shaft. The driving pulley 604 and the driven pulley 602 are located in the same horizontal plane, and a transmission belt 606 connects the driving pulley 604 and the driven pulley 602.

[0044] The working section of the drive belt 606 passes through the power input wheel 301 of each false twister 3 on the A-side station or the B-side station, providing power input to each false twister 3. The return section of the drive belt 606 passes through the rotation zone 4.

[0045] Based on the above embodiments, the two transmission units 6 configured in this application have the same structure and are respectively located at the A-side station and the B-side station. Since the only difference between the A-side station and the B-side station in the false twist working area is the arrangement direction of each false twister 3, and the two sets of tensioning components 7 in each transmission unit also have the same structure, this application achieves the following: Figure 3 Based on the staggered arrangement of the two driving pulleys 604 and two driven pulleys 602 shown, the positions of the driving motor 601 and driving pulley 604 in each transmission unit 6 of this application can be interchanged with the positions of the driven pulleys 602. That is, in one embodiment, both driving motors 601 and two driving pulleys 604 are located on the front frame 1, and both driven pulleys 602 are located on the rear frame 2; in another embodiment, both driving motors 601 and two driving pulleys 604 are located on the rear frame 2, and both driven pulleys 602 are located on the front frame 1. The above different arrangements do not affect the implementation of the technical solution of this application and should all fall within the protection scope of this application.

[0046] Additionally, in this application, such as Figure 4 As shown, the tensioning assembly 7 includes a set of support crossbars 701 arranged parallel to the front frame 1 or the rear frame 2, and the extension direction of the set of support crossbars 701 is the same as the extension direction of the two rows of false twisters 3. Each support crossbar 701 is provided with an elongated hole 702, and the elongated holes 702 are arranged along the extension direction of the support crossbar 701. The elongated holes 702 are connected to the motor mounting plate 603 or the driven pulley mounting plate 605 by connecting bolts, and the connecting bolts are also provided with connecting plates with screw holes. By adjusting the mating position of the connecting bolts and the elongated holes 702, the connection position of the motor mounting plate 603 or the driven pulley mounting plate 605 on the support crossbars 701 can be adjusted, thereby adjusting the distance between the driving pulley 604 and the driven pulley 602, which is used to tension the drive belt 606.

[0047] In addition, such as Figure 4As shown, the tensioning assembly 7 also includes an angle iron 703 mounted on a set of support crossbars 701, with the angle iron 703 perpendicular to the support crossbars 701. The angle iron 703 includes an integrally connected horizontal part and a vertical part. The horizontal part is fixedly connected to the set of support crossbars 701, and a set of adjusting screws 704 are provided through the vertical part. Each adjusting screw 704 extends from one end of the vertical part near the motor mounting plate 603 or the driven pulley mounting plate 605 to above the motor mounting plate 603 or the driven pulley mounting plate 605. A transmission sprocket 705 and a fixing nut 706 are fixedly provided at the end of the straight part away from the motor mounting plate 603 or the driven pulley mounting plate 605. The transmission sprocket 705 and the fixing nut 706 are fixedly connected to the adjusting screw 704. In addition, both the motor mounting plate 603 and the driven pulley mounting plate 605 are provided with a set of fixing blocks 707 with screw holes, and the fixing blocks 707 with screw holes correspond one-to-one with the adjusting screw 704 and are threadedly connected. In the tensioning assembly 7, the transmission sprockets 705 on a set of adjusting screws 704 are connected to a transmission chain 708.

[0048] Based on the above embodiments, when it is necessary to tension the transmission belt 606 on the A-side workstation or the B-side workstation, the operator only needs to use a wrench or other tools to rotate the fixing nut 706 at the end of any adjusting screw 704 on the A-side workstation or the B-side workstation. The rotation of the fixing nut 706 drives the rotation of the transmission sprocket 705 and the adjusting screw 704. With the cooperation of the transmission sprocket 705 and the transmission chain 708, the two adjusting screws 704 are rotated synchronously, thereby smoothly adjusting the position of the motor mounting plate 603 or the driven pulley mounting plate 605.

[0049] In this technical solution, the double-dragon belt false twister transmission device also includes an offset guide component 8, an offset limiting guide component 9, a longitudinal limiting guide component 10, and a transverse limiting guide component 11; the offset guide component 8 is located at both ends of the A-side station and the B-side station, the offset limiting guide component 9 is located at the position corresponding to the power input wheel 301 of the false twister 3 in the A-side station and the B-side station, and the longitudinal limiting guide component 10 and the transverse limiting guide component 11 are located in the rotation zone 4.

[0050] Among them, such as Figure 5As shown, the offset guide assembly 8 is located on the front wall panel 101 and the rear wall panel 201. Both sets of offset guide assemblies 8 are symmetrically arranged on the front wall panel 101 and the rear wall panel 201, respectively acting on the A-side workstation and the B-side workstation. The offset guide assembly 8 includes a first mounting frame 801, on which two centrally symmetrical L-shaped mounting plates 802 are provided. Each L-shaped mounting plate 802 is rotatably equipped with an offset guide wheel 803, and the area between the two offset guide wheels 803 allows the working section of the transmission belt 606 to pass through. The two offset guide wheels 803 are arranged parallel to each other, and each offset guide wheel 803 forms an offset angle with the vertical direction. This offset angle is adapted to the installation angle of the false twister 3, so that the two offset guide wheels 803 deflect and guide the working section of the transmission belt 606.

[0051] The longitudinal limiting guide component 10 and the transverse limiting guide component 11 are alternately located on several different intermediate wall panels 5, and the intermediate wall panel 5 on which the longitudinal limiting guide component 10 is provided is also provided with an offset limiting guide component 9.

[0052] More specifically, such as Figures 6 to 7 As shown, the longitudinal limiting guide assembly 10 includes a second mounting bracket 1001, on which two first guide wheels 1002 are arranged in parallel. Each first guide wheel 1002 is horizontally arranged and is located above and below the transmission belt 606, respectively. Two sets of longitudinal limiting guide assemblies 10 are provided on the intermediate wall plate 5, and both sets of longitudinal limiting guide assemblies 10 are located within the turning area 4. The two sets of longitudinal limiting guide assemblies 10 are located on both sides of the intermediate wall plate 5. The two sets of longitudinal limiting guide assemblies 10 are used to limit the longitudinal vertical position of the return section of the transmission belt 606 of the A-side station and the B-side station, respectively.

[0053] like Figure 8 As shown, the lateral limiting guide assembly 11 includes a third mounting bracket 1101, on which two second guide wheels 1102 are arranged in parallel. Each second guide wheel 1102 is arranged vertically and is located on the left and right sides of the transmission belt 606, respectively. Two sets of lateral limiting guide assemblies 11 are provided on the intermediate wall plate 5, and both sets of lateral limiting guide assemblies 11 are located within the turning area 4. The two sets of lateral limiting guide assemblies 11 are located on both sides of the intermediate wall plate 5. The two sets of lateral limiting guide assemblies 11 are used to limit the lateral horizontal position of the return section of the transmission belt 606 of the A-side station and the B-side station, respectively.

[0054] like Figure 9As shown, the offset limiting guide assembly 9 includes a fourth mounting bracket 901, on which two third guide wheels 902 are arranged in parallel. Each third guide wheel 902 forms the same offset angle with the vertical direction as the offset guide wheel 803, and the two third guide wheels 902 are located on both sides of the transmission belt 606 along the width extension direction of the transmission belt 606. On each intermediate wall plate 5 where the longitudinal limiting guide assembly 10 is provided, two sets of offset limiting guide assemblies 9 are also provided, and the two sets of offset limiting guide assemblies 9 are located at the positions near the false twister 3 in the A-side work position and the B-side work position, respectively. The two sets of offset limiting guide assemblies 9 are located on both sides of the intermediate wall plate 5, and the two sets of offset limiting guide assemblies 9 are used to provide position limitation along the offset angle direction for the working section of the transmission belt 606 in the A-side work position and the B-side work position, respectively.

[0055] In general, the double-draft false twister transmission device for the false twisting texturer of this application has two identical transmission units 6 set up at the A-side and B-side workstations respectively. Each transmission unit 6 consists of a drive motor 601, a drive pulley 604, a driven pulley 602, a transmission belt 606, and two sets of tensioning components 7. During operation, the drive motor 601 outputs power and drives the drive pulley 604 to rotate. The drive pulley 604 then drives the transmission belt 606, which is tensioned between itself and the driven pulley 602, to run in a cycle, thus forming an independent transmission circuit on the corresponding side workstation. Since the two transmission units 6 correspond to the false twisters 3 in the A-side and B-side workstations respectively, the false twisters 3 in the A-side and B-side workstations can obtain independent power inputs, thereby enabling the two sides of the false twisting texturer to perform independent transmission and differentiated operation according to actual production needs, so as to meet the processing requirements of different varieties of products and improve the adaptability of the equipment to multi-variety, small-batch production.

[0056] The working section of the drive belt 606 passes through the power input wheel 301 of each false twister 3 on the corresponding side station, and transmits power to each false twister 3 in sequence to drive the false twister 3 to work continuously. The return section of the drive belt 606 passes through the rotation area 4 located between the A side station and the B side station, completing the cyclic rotation of the entire transmission path. In order to make the working section of the drive belt 606 compatible with the installation angle of the false twister 3, offset guide components 8 are set at both ends of the A side station and the B side station. The drive belt 606 is deflected and guided by two offset guide wheels 803 with preset offset angles, so that the drive belt 606 enters each false twister 3 at an angle suitable for the power input of the false twister 3. At the same time, the offset limiting guide components 9 set on each intermediate wall plate 5 limit the position of the drive belt 606 in the working section along the offset angle direction to prevent the drive belt 606 from deviating or moving during the cooperation with the false twister 3.

[0057] In addition, to ensure the stability of the transmission belt 606 during long-distance operation within the turning zone 4, longitudinal limiting guide components 10 and lateral limiting guide components 11 are alternately installed on each intermediate wall plate 5. The longitudinal limiting guide component 10 limits the vertical position of the return section through two first guide wheels 1002 located above and below the transmission belt 606; the lateral limiting guide component 11 limits the lateral position of the return section through two second guide wheels 1102 located on the left and right sides of the transmission belt 606. Through the cooperation of longitudinal and lateral dual limiting, the risk of deviation, slippage and vibration of the transmission belt 606 during long-distance turning operation is effectively reduced, and the smoothness of the transmission process and the reliability of power output are improved.

[0058] Furthermore, when it is necessary to adjust the tension of the drive belt 606, the operator can adjust the position of the motor mounting plate 603 or the driven pulley mounting plate 605 through the tensioning component 7. Specifically, the motor mounting plate 603 or the driven pulley mounting plate 605 is installed in conjunction with the elongated hole 702 on the support crossbar 701, and its position can be adjusted along the extension direction of the support crossbar 701 to change the center distance between the drive pulley 604 and the driven pulley 602, thereby achieving tension of the drive belt 606. At the same time, by rotating the fixing nut 706 at the end of any adjusting screw 704, under the linkage of the drive sprocket 705 and the drive chain 708, a set of adjusting screws 704 can be driven to rotate synchronously, thereby making the motor mounting plate 603 or the driven pulley mounting plate 605 move smoothly, which facilitates the synchronous and uniform tension of the drive belt 606, further ensuring the transmission effect and the stability of the whole machine operation.

[0059] In summary, this application, by setting up two independent transmission units 6 corresponding to the A-side workstation and the B-side workstation respectively, and combining them with the offset guide assembly 8, the offset limit guide assembly 9, the longitudinal limit guide assembly 10, the transverse limit guide assembly 11 and the tensioning assembly 7, not only realizes the independent power transmission of the false twisters 3 on both sides of the false twist deformation machine, but also effectively solves the problems of deviation, slippage and unstable tension that easily occur in the double-draft belt during long-distance operation, thereby improving the operational stability and reliability of the transmission device and the adaptability of the equipment to different product processing conditions.
