Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a doubling machine and its winding device. Background Technology

[0002] A doubling twister is a twisting device used in the textile industry, primarily for producing yarns or fibers with specific strength and structure through a twisting process. Its core feature is the ability to complete two twisting operations (i.e., "double twisting") in a single process.

[0003] During operation, a doubling machine employs a winding structure to wind up the yarn. For example, CN222715525U discloses a winding device for a high-speed doubling machine, including a mounting plate. A fixed plate is fixedly connected to one side of the mounting plate, and a mounting assembly is provided on the surface of the mounting plate. A motor frame is fixedly connected to one side of the fixed plate, and a drive motor is installed inside the motor frame. A support cylinder is provided on the output shaft of the drive motor. A connecting shaft is sleeved on the inner side of the mounting plate through a bearing A. A threaded rod is fixedly connected to one end of the connecting shaft, and a connecting rod is fixedly connected to one end of the threaded rod. A knob is fixedly connected to one end of the connecting rod. A threaded sleeve and a limiting nut are threadedly connected to the surface of the threaded rod. A first adjusting frame is fixedly connected to one side of the threaded sleeve, and a second adjusting frame is fixedly connected to one side of the first adjusting frame. A limiting assembly is provided between the first adjusting frame and the mounting plate. An adjusting plate is fixedly connected to one side of the second adjusting frame, and a limiting shaft is sleeved on one side of the adjusting plate through a bearing B. A limiting ring is fixedly connected to the surface of the limiting shaft, and a winding wheel is engaged between the limiting shaft and the limiting ring and the support cylinder.

[0004] When installing or disassembling the winding wheel, the aforementioned winding device requires workers to provide auxiliary support to the winding wheel before they can operate the knob to install or disassemble it, which makes the process relatively strenuous for the workers. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a twisting machine and its winding equipment to solve the problem that it is relatively difficult for workers to install or disassemble the winding wheel in the existing technology.

[0006] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a winding device for a doubling machine, comprising a support base and a clamping assembly disposed on the support base for assembling a winding wheel, wherein the support base is further provided with a lifting assembly that moves in the direction perpendicular to the central axis of the clamping assembly, the lifting assembly comprising:

[0007] A lifting seat, which is slidably connected to a support seat along the perpendicular direction of the central axis of the clamping assembly;

[0008] A lifting device, which is fixedly connected to the support base and connected to the bottom of the lifting base, is used to drive the lifting base to slide;

[0009] The support section has multiple sections arranged at intervals along the axial direction after the winding wheel is installed. The multiple support sections are fixedly connected to the top of the lifting seat. Each support section has a receiving groove and an extended receiving opening formed by extending outward from the top of the receiving groove.

[0010] When installing the take-up reel:

[0011] The winding reel is placed in the receiving slots of multiple support parts for support. Then, the lifting device operates to drive the lifting seat to move upward until the winding reel is lifted into the installation position of the clamping assembly. At this time, the lifting device stops operating. Then, the clamping assembly is operated to clamp and fix the winding reel, completing the installation of the winding reel. At this time, the lifting device drives the lifting seat to move downward to the initial position to avoid the multiple support parts affecting the operation of the winding reel.

[0012] When splitting the take-up reel:

[0013] The lifting mechanism operates to drive the lifting platform upwards until the winding reel is placed against the extended receiving opening or receiving slot, at which point the lifting mechanism stops operating; then the clamping assembly is operated to disengage the winding reel from its clamping and fixing, completing the disassembly of the winding reel.

[0014] The second aspect of this utility model adopts the following technical solution: a twisting machine, including a winding device as described in the first aspect of this utility model.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. During the process of clamping and fixing or detaching the winding wheel by the clamping components of this twisting machine, the winding wheel is stably supported by the lifting seat, the top lifter and multiple support parts, which makes it easier and less strenuous for the workers to install or remove the winding wheel.

[0017] 2. The receiving groove and extended receiving opening in the support part of the winding equipment of this twisting machine can stably support the unwound winding wheel, the wound winding wheel, and winding wheels of different sizes. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below through specific embodiments:

[0025] like Figures 1-5 As shown in the figure, this utility model embodiment proposes a winding device for a doubling machine, including a support base 1 and a clamping assembly 3 disposed on the support base 1 for assembling a winding wheel 2. The support base 1 is also provided with a lifting assembly 4 that moves in the direction perpendicular to the central axis of the clamping assembly 3. The lifting assembly 4 includes a lifting seat 41, a lifting device 42, and a support part 43. The lifting seat 41 is slidably connected to the support base 1 in the direction perpendicular to the central axis of the clamping assembly 3. The lifting device 42 is fixedly connected to the support base 1 and connected to the bottom of the lifting seat 41 for driving the lifting seat 41 to slide. There are multiple support parts 43, which are spaced apart in the axial direction after the winding wheel 2 is installed. Multiple support parts 43 are fixedly connected to the top of the lifting seat 41. Each support part 43 has a receiving groove 431 and an extended receiving opening 432 formed by extending outward from the top of the receiving groove 431.

[0026] When installing take-up reel 2:

[0027] The take-up reel 2 is placed in the receiving slots 431 of multiple support parts 43 for support. Then, the lifting device 42 operates to drive the lifting seat 41 to move upward until the take-up reel 2 is lifted into the installation position of the clamping assembly 3. At this time, the lifting device 42 stops operating. Then, the clamping assembly 3 is operated to clamp and fix the take-up reel 2, completing the installation of the take-up reel 2. At this time, the lifting device 42 drives the lifting seat 41 to move downward to the initial position to avoid the multiple support parts 43 affecting the operation of the take-up reel 2.

[0028] When the take-up reel 2 is split:

[0029] The lifting device 42 operates to drive the lifting seat 41 to move upward until the winding wheel 2 is placed in the extended receiving opening 432 or the receiving slot 431 and abuts against it. At this time, the lifting device 42 stops operating. Then, the clamping assembly 3 is operated to disengage the winding wheel 2 from the clamp and fix it, thus completing the disassembly of the winding wheel 2.

[0030] In this embodiment, guide blocks are connected to both ends of the lifting seat 41, and each guide block is fitted with a guide limiting groove 5 formed on the support seat 1. When the lifting device 42 operates to drive the lifting seat 41 to move upward, the two guide blocks slide upward in the corresponding guide limiting groove 5 until the top of the guide blocks slide into the corresponding guide limiting groove 5 and abut against each other. At this time, the lifting device 42 stops operating, and the winding wheel 2 is lifted into the mounting position of the clamping assembly 3 so as to cooperate with the clamping assembly 3. After the winding wheel 2 is installed, the lifting device 42 drives the lifting seat 41 to move downward, and the two guide blocks slide downward in the corresponding guide limiting groove 5 until the bottom of the guide blocks slide into the corresponding guide limiting groove 5 and abut against each other. At this time, the lifting device 42 stops operating to prevent the support part 43 from restricting the winding operation of the winding wheel 2.

[0031] The number of support parts 43 is shown as two, but can be adjusted according to actual needs; and the lifting device 42 can be a cylinder or an electric telescopic rod.

[0032] To better understand this solution, the following will describe the structure of the support part 43 and the clamping assembly 3.

[0033] First is the support section 43.

[0034] like Figure 1 , Figure 3 as well as Figure 5 As shown, according to another embodiment of the present invention, the winding device of the doubling machine, wherein each of the support parts 43 further includes a support body 433 and an extended support ear 434, the support body 433 is fixedly connected to the top of the lifting seat 41 and the receiving groove 431 is opened on the top of the support body 433; there are two extended support ears 434 arranged facing each other on both sides of the top of the support body 433, and the two extended support ears 434 cooperate to form the extended receiving opening 432.

[0035] In this embodiment, the support body 433 serves as the main structure of the support part 43 and is specifically U-shaped. The two extended support ears 434 are designed at both ends of the support body 433 to form an expanded receiving opening 432 above the receiving groove 431, so as to provide stable support for the winding wheel 2 after winding and winding wheels 2 of different sizes.

[0036] The two extended support ears 434 are symmetrically arranged and each includes an inclined guide section 43a, an extended planar section 43b, and an extended arc section 43c that are sequentially connected to the opening of the receiving groove 431.

[0037] Specifically, in this embodiment, one end of the extended planar segment 43b is connected to the end of the inclined guide segment 43a that is farther from the central axis of the receiving groove 431. The extended arc segment 43c is curved and recessed towards the central axis of the receiving groove 431, and the end of the extended arc segment 43c that is closer to the central axis of the receiving groove 431 is connected to the other end of the extended planar segment 43b. This arrangement allows the two extended support ears 434 to provide stable support for winding wheels 2 of different sizes. On the other hand, it also reduces the vertical height of the extended support ears 434. When the lifting seat 41 moves to the initial position, there is a greater distance between the extended support ears 434 and the installed winding wheel 2, which is beneficial for the winding operation of the winding wheel 2.

[0038] Secondly, there is the clamping component 3.

[0039] like Figures 1-4 As shown, according to another embodiment of the present invention, the winding device of the doubling machine includes a clamping assembly 3 comprising a mounting base 31 and an adjusting part. There are two mounting bases 31 arranged facing each other on the support base 1. The facing surfaces of the two mounting bases 31 are rotatably connected to mounting sleeves 32 for spline connection to one end of the winding wheel 2. A first driver 33 for driving the corresponding mounting sleeve 32 to rotate is connected to one of the mounting bases 31. The adjusting part is connected to the two mounting bases 31 and is used to drive the two mounting bases 31 to move towards or away from each other.

[0040] In this embodiment, the adjustment part includes an adjustment screw 34 and an adjustment block 35. The adjustment screw 34 is rotatably connected to the side of the support base 1 away from the mounting base 31, and one end of the screw is connected to a second driver 36 that drives the screw 34 to rotate. There are two adjustment blocks 35, both of which are threadedly connected to the adjustment screw 34. The two adjustment blocks 35 are connected to the two mounting bases 31 one-to-one through limiting blocks. The limiting blocks are slidably limited in the guide holes 37 opened on the support base 1 and distributed along the line connecting the two mounting bases 31.

[0041] When it is necessary to clamp and fix the take-up reel 2:

[0042] When the take-up reel 2 is placed in the mounting position of the clamping assembly 3 (i.e., the central axis of the take-up reel 2 is collinear with the line connecting the two mounting seats 31), the second driver 36 is activated. The second driver 36 drives the adjusting screw 34 to rotate. Through the guide hole 37, the two limiting blocks are limited and guided. The two adjusting blocks 35 move towards each other on the adjusting screw 34. The two adjusting blocks 35 drive the two mounting seats 31 to move towards each other through the transmission of the two limiting blocks until both ends of the take-up reel 2 are completely embedded in the two mounting sleeves 32, thus completing the installation of the take-up reel 2.

[0043] After the take-up reel 2 is installed and the lifting seat 41 moves back to its initial position, the take-up reel 2 can be used to engage the yarn. Then, the first driver 33 can be started to drive the take-up reel 2 to wind up the yarn.

[0044] When it is necessary to release the take-up reel 2 from the clamp:

[0045] First, the lifting assembly 4 is operated, and the take-up reel is supported by the support part 43. Then, the second driver 36 is operated, which drives the adjusting screw 34 to rotate in the opposite direction. Through the guide hole 37, the two limit blocks are limited and guided. The two adjusting blocks 35 move away from each other on the adjusting screw 34. The two adjusting blocks 35 drive the two mounting seats 31 to move away from each other through the transmission of the two limit blocks until the two ends of the take-up reel 2 are disengaged from the two mounting sleeves 32, and the take-up reel 2 can be removed.

[0046] When the take-up reel 2 is removed, the lifting assembly 4 is operated to return to the initial position for the next use.

[0047] Both the first driver 33 and the second driver 36 can be stepper motors.

[0048] Next, in order to improve the safety performance of the adjusting screw 34 and the second drive 36, such as... Figure 2 and Figure 4 As shown, according to another embodiment of the present invention, the winding device of the double twister is wherein the support base 1 is connected to the insertion seat 6 located below the adjusting screw 34, the top of the insertion seat 6 is formed with an insertion groove, and a protective cover 7 for covering the adjusting screw 34 and the second driver 36 is inserted into the insertion groove.

[0049] In this embodiment, the protective cover 7 is square, with its side that connects to the support base 1 and the connector 6 both open. During installation, the protective cover 7 is held by its top handle, and the end of the protective cover 7 that connects to the support base 1 is pressed against the support base 1 and slid downwards until the open end of the protective cover 7 at the bottom is inserted into the connector slot on the connector 6 for a relatively stable connection. At this time, the adjusting screw 34 and the second actuator 36 are both placed inside the protective cover 7 for protection. This structural arrangement makes the installation and disassembly of the protective cover 7 relatively convenient.

[0050] In order to enable the protective cover 7 to have good heat dissipation capacity, the protective cover 7 has a number of heat dissipation holes 71.

[0051] The continuation is to facilitate the installation of this winding equipment onto a doubling machine, such as... Figures 1-4 As shown, according to another embodiment of the present invention, the winding device of the double twister, wherein both ends of one side of the support base 1 are formed with connecting ears 8 extending outward therefrom, and a receiving space for accommodating the protective cover 7 is formed between the two connecting ears 8 and the support base 1.

[0052] In this embodiment, each of the connecting lugs 8 is L-shaped and has mounting holes, which are then used to connect to the twisting machine via bolts. The two connecting lugs 8, together with the support base 1, form a accommodating chamber to house the installed protective cover 7, thus providing protection for the cover 7.

[0053] When installing take-up reel 2:

[0054] The take-up reel 2 is placed in the receiving groove 431 of multiple support parts 43 for support. Then the lifting device 42 operates to drive the lifting seat 41 to move upward until the take-up reel 2 is lifted into the mounting position of the clamping assembly 3. At this time, the lifting device 42 stops operating. Then the second driver 36 is operated to drive the adjusting screw 34 to rotate. The two limiting blocks are limited and guided by the guide hole 37. The two adjusting blocks 35 move towards each other on the adjusting screw 34. The two adjusting blocks 35 drive the two mounting seats 31 to move towards each other through the transmission of the two limiting blocks until both ends of the take-up reel 2 are completely embedded in the two mounting sleeves 32, thus completing the installation of the take-up reel 2.

[0055] Then the lifting device 42 is activated to drive the lifting seat 41 to move downwards to return to the initial position.

[0056] When the take-up reel 2 is split:

[0057] The lifting device 42 is operated to drive the lifting seat 41 to move upward until the winding wheel 2 is placed in the extended receiving opening 432 or the receiving groove 431 and abuts against each other. At this time, the lifting device 42 stops operating. Then the second driver 36 is operated to drive the adjusting screw 34 to rotate in the opposite direction. The two limiting blocks are limited and guided by the guide hole 37. The two adjusting blocks 35 move away from each other on the adjusting screw 34. The two adjusting blocks 35 drive the two mounting seats 31 to move away from each other through the transmission of the two limiting blocks until the two ends of the winding wheel 2 are disengaged from the two mounting sleeves 32. The winding wheel 2 can then be removed.

[0058] Then the lifting device 42 is activated to drive the lifting seat 41 to move downwards to return to the initial position.

[0059] The winding device is applied to a doubling twister. According to another embodiment of the present invention, the doubling twister includes a winding device as described in any of the above embodiments, so that the doubling twister has the advantages of the winding device described above.
