Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to an adjustable winding cart pallet. Background Technology

[0002] In the field of worsted spinning, the winding process is a crucial step, providing the necessary yarn preparation for subsequent spinning processes. With the continuous advancement of the textile industry, the demands for spinning efficiency and quality are constantly increasing. As a key piece of equipment in the winding process, the performance of the winding machine directly affects the efficiency and quality of the entire spinning production, playing a vital role in promoting the development of the entire worsted spinning industry.

[0003] In the traditional worsted spinning winding process, the yarn was typically prepared by placing the yarn spindles on trays. However, traditional trays are mostly of fixed size, which cannot flexibly accommodate different yarn diameters. This forces workers to frequently change trays manually, a cumbersome and time-consuming operation that severely impacts production efficiency, increases labor intensity, and disrupts the continuity and stability of production.

[0004] To address this issue, Chinese Patent No. CN203345837U discloses a yarn tube fixing mechanism for a winding machine, comprising a base, a fixing post, a washer, a yarn sleeve, and an adjusting cover. The base is fitted onto the fixing post and positioned at the lower part of the fixing post. The washer is fitted onto the fixing post, and the lower part of the yarn sleeve is positioned on the upper part of the base after being fitted onto the fixing post. The adjusting cover is positioned on the upper part of the fixing post.

[0005] However, the yarn bobbin fixing mechanism of this winding machine still has significant stability defects under actual working conditions, making it difficult to meet the requirements of high-speed operation of the winding machine. During operation, the yarn bobbin continuously vibrates as the yarn winds around, and during unwinding, a radial tension is applied to the inner wall of the bobbin. This force is directly transmitted to the yarn sleeve, and then acts in the opposite direction on the adjusting cover. Since the adjusting cover is connected to the fixed post via only a single thread, it is prone to loosening or circumferential deflection under continuous vibration and radial force. This leads to an imbalance in the radial expansion force of the yarn sleeve. In mild cases, this results in yarn bobbin positioning misalignment, causing yarn winding tension fluctuations; in severe cases, it causes radial contraction of the yarn sleeve, leading to bobbin jumps during high-speed rotation. This not only causes yarn breakage and yarn waste, but may also cause equipment jamming, severely reducing the processing stability and production safety of the winding machine. Utility Model Content

[0006] To improve the stability of the winding cart pallet in fixing fine yarns of different diameters, this application provides an adjustable winding cart pallet.

[0007] The adjustable winding cart pallet provided in this application adopts the following technical solution: An adjustable winding cart pallet includes a pallet base, a central support column, an adjusting block, and a multi-lobed clamping ring assembly. The central support column is vertically connected to the center of the pallet base and has an adjusting thread along its axial direction. The adjusting block is rotatably fitted onto the central support column via the thread. The multi-lobed clamping ring assembly is located between the pallet base and the adjusting block and includes a pressure ring coaxially contacting the adjusting block, a positioning ring coaxially contacting the pallet base, and several arc-shaped clamping lobes. The arc-shaped clamping lobes connect the pressure ring and the positioning ring. The petals are evenly distributed around the central support column and bend toward the side away from the central support column. A self-locking assembly is provided between the central support column and the adjusting block. The self-locking assembly is located at the top of the central support column and includes a ratchet disc, a pawl, and a return spring. The ratchet disc is located at the top of the adjusting block and is coaxially connected to the adjusting block. The pawl is hinged to the top side wall of the central support column via a pivot. One end of the return spring is connected to the pawl, and the other end is fixed to the side wall of the central support column. The movable end of the pawl is inserted into the inner tooth groove of the ratchet disc.

[0008] By adopting the above technical solution, when the winding cart pallet is adapted to a large-diameter fine yarn, rotating the adjusting block will cause the adjusting block to move axially downward along the adjusting thread of the central support column, driving the pressure ring to move downward, causing the arc-shaped clamping petals of the multi-lobed clamping ring assembly to expand outward, and simultaneously unfolding the multi-lobed clamping ring assembly; during this process, the ratchet disk rotates with the adjusting block, and the pawl slides unidirectionally along the inner ring tooth groove of the ratchet disk under the action of the return spring. After the diameter of the multi-lobed clamping ring assembly is adapted to the diameter of the fine yarn, the pawl is embedded in the tooth groove and automatically locked, avoiding the situation where the adjusting block's threads loosen or circumferentially deflect under the action of the fine yarn vibration and the radial tension of the yarn, effectively improving the stability of the winding cart pallet in fixing fine yarn of different diameter sizes.

[0009] Optionally, the self-locking assembly further includes an unlocking lever, which includes a positioning rod, a plug-in rod, and a connecting rod connecting the positioning rod and the plug-in rod. The positioning rod and the plug-in rod are both parallel to the pawl's axis of rotation. The positioning rod is slidably disposed on the top wall of the pawl and located on the side close to the movable end of the pawl. Plug-in holes are provided on the top wall of the central support column and the top wall of the pawl. The plug-in rod is plugged into the plug-in hole. When the plug-in rod is plugged into the plug-in hole on the top wall of the central support column, the pawl disengages from the inner tooth groove of the ratchet disc.

[0010] By adopting the above technical solution, when the winding cart pallet needs to be adjusted to accommodate small-diameter fine yarn, the insertion rod can be pulled out towards the side away from the pawl. The connecting rod then rotates the movable end of the pawl away from the ratchet disc until the insertion rod engages with the insertion hole on the top wall of the central support column. At this point, the pawl disengages from the inner tooth groove of the ratchet disc, allowing the adjusting block to rotate in the opposite direction and move axially upwards. The multi-lobed clamping ring assembly retracts inwards under its own elasticity or other forces, thus simultaneously reducing the size of the multi-lobed clamping ring assembly. After adjustment to the target diameter, the insertion rod is pulled out of the central support column and reinserted into the insertion hole on the top wall of the pawl. Under the action of the return spring, the movable end of the pawl re-engages in the inner tooth groove of the ratchet disc, achieving flexible adjustment and locking of the winding cart pallet diameter.

[0011] Optionally, the end of the plug rod is provided with a snap-fit ​​ball, and the top wall of the central support column and the top wall of the pawl are both provided with snap-fit ​​grooves that communicate with the plug hole, and the snap-fit ​​ball and the snap-fit ​​groove are engaged in a snap-fit ​​fit.

[0012] By adopting the above technical solution, the locking ball and the locking groove are engaged to ensure that the unlocking lever can be stably held in a specific position after operation, avoiding displacement of the unlocking lever due to vibration and other factors, and ensuring that the pawl can reliably disengage from or engage with the inner ring tooth groove of the ratchet disc, thereby further improving the stability and reliability of the self-locking component.

[0013] Optionally, a rotating ring is rotatably connected to the central support column. The rotating ring is located near the tray base. Several support rods are connected between the rotating ring and the ratchet disk. The support rods are evenly distributed along the circumference of the ratchet disk, are parallel to the central support column, and slide through the adjusting block.

[0014] By adopting the above technical solution, the swivel ring and the ratchet disc are connected by a support rod, and the support rod slides through an adjusting block. This allows the ratchet disc to rotate in place when the adjusting block moves up and down, reducing the risk of the pawl disengaging from the ratchet disc. At the same time, when the adjusting block rotates, the swivel ring can rotate accordingly, reducing the risk of wobbling when the ratchet disc rotates and further improving the overall stability of the winding cart pallet.

[0015] Optionally, an elastic connecting strip connects two adjacent arc-shaped clamping petals.

[0016] By adopting the above technical solution, adjacent arc-shaped clamping petals are connected by elastic connecting strips made of fatigue-resistant rubber, which not only retains the radial expansion margin but also ensures the circumferential uniformity during expansion. This enhances the overall stability and coordination of the multi-petal clamping ring assembly and reduces the risk of misalignment or separation of the arc-shaped clamping petals during adjustment.

[0017] Optionally, the tray base is provided with an mounting ring groove, a pre-tightening rubber pad is inserted into the mounting ring groove, and the positioning ring is inserted into the mounting ring groove and abuts against the pre-tightening rubber pad.

[0018] By adopting the above technical solution, the pre-tightening rubber pad can provide a continuous upward pre-tightening force for the positioning ring, so that the pressure ring and the conical surface of the adjusting block are always in close contact. It can also absorb the impact energy when the winding car vibrates, reducing the impact of vibration on the winding car pallet adjustment structure.

[0019] Optionally, the outer ring of the pressure ring is provided with a frustum-shaped inclined surface to facilitate the fitting of the fine yarn webbing.

[0020] By adopting the above technical solution, setting a truncated cone-shaped inclined surface on the outer ring of the pressure ring can reduce the difficulty of setting the fine yarn weave, improve the ease of setting, and thus improve the operating efficiency.

[0021] Optionally, the outer ring of the adjusting block is provided with several anti-slip protrusions.

[0022] By adopting the above technical solution, several anti-slip ridges are provided around the outer ring of the adjusting block, which can increase the friction between the hand and the adjusting block, making it easier for the operator to rotate the adjusting block, making the adjustment process easier and more efficient, and thus improving the convenience of adjusting the winding cart pallet.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When the winding cart pallet is adapted to a large-diameter fine yarn, rotating the adjusting block will cause it to move axially downward along the adjusting thread of the central support column, driving the pressure ring to move downward. This causes the arc-shaped clamping petals of the multi-lobed clamping ring assembly to expand outward, simultaneously unfolding the multi-lobed clamping ring assembly. During this process, the ratchet disk rotates with the adjusting block, and the pawl slides unidirectionally along the inner tooth groove of the ratchet disk under the action of the return spring. After the diameter of the multi-lobed clamping ring assembly is adapted to the diameter of the fine yarn, the pawl automatically locks into the tooth groove, preventing the adjusting block from becoming loose or circumferentially deflected under the action of the fine yarn vibration and the radial tension of the yarn. This effectively improves the stability of the winding cart pallet in fixing fine yarns of different diameters. 2. When the winding cart pallet needs to be adjusted to accommodate small-diameter fine yarn, pull out the connecting rod away from the pawl. Use the connecting rod to rotate the movable end of the pawl away from the ratchet until the connecting rod engages with the insertion hole on the top wall of the central support column. At this point, the pawl disengages from the inner tooth groove of the ratchet, allowing the adjusting block to rotate in the opposite direction and move axially upwards. The multi-lobed clamping ring assembly retracts inwards under its own elasticity or other forces, thus simultaneously reducing the size of the multi-lobed clamping ring assembly. After adjusting to the target diameter, pull the connecting rod out of the central support column and reinsert it into the insertion hole on the top wall of the pawl. Under the action of the return spring, the movable end of the pawl re-engages in the inner tooth groove of the ratchet, achieving flexible adjustment and locking of the winding cart pallet diameter. 3. By utilizing the snap-fit ​​mechanism between the snap-fit ​​ball and the snap-fit ​​groove, the unlocking lever can be stably held in a specific position after operation, preventing the unlocking lever from shifting due to vibration or other factors. This ensures that the pawl can reliably disengage from or engage with the inner tooth groove of the ratchet disc, further improving the stability and reliability of the self-locking component.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses an adjustable winding cart pallet.

[0031] Reference Figure 1 An adjustable winding cart pallet includes a pallet base 1, a central support column 2, an adjusting block 3, a multi-lobed clamping ring assembly 4, and a self-locking assembly 5. The central support column 2 is vertically connected to the center of the pallet base 1. The adjusting block 3 is screwed onto the central support column 2. The multi-lobed clamping ring assembly 4 is located between the pallet base 1 and the adjusting block 3. The self-locking assembly 5 is located at the top of the central support column 2.

[0032] Reference Figure 1 and Figure 2 The pallet base 1 is a circular plate structure with four evenly distributed mounting holes 11 running through its surface along its own axis for bolting to the winding vehicle body. It also has a positioning recess 12 in the center for mounting the central support column 2. The central support column 2 is perpendicular to the center of the pallet base 1, slides through the positioning recess 12, and is fixed to the pallet base 1 by bolts.

[0033] Reference Figure 1 and Figure 2 The central support column 2 has an adjusting thread along its own axis. The inner ring of the adjusting block 3 has an internal thread that matches the adjusting thread of the central support column 2. The outer ring of the adjusting block 3 has several anti-slip protrusions 31. The adjusting block 3 is screwed onto the central support column 2 by rotating the thread. The adjusting block 3 is tapered towards the outer side wall of the tray base 1.

[0034] Reference Figure 1 and Figure 2 The multi-lobed clamping ring assembly 4 is located between the tray base 1 and the adjusting block 3, including a pressure ring 41, a positioning ring 42 and several arc-shaped clamping lobes 43. The outer ring of the pressure ring 41 is provided with a frustum-shaped inclined surface to facilitate the fitting of the fine yarn webbing. The inner wall of the pressure ring 41 is a conical surface adapted to the conical structure of the adjusting block 3. The pressure ring 41 and the adjusting block 3 are coaxially arranged and abut against each other through the conical surface.

[0035] Reference Figure 1 and Figure 2 The pallet base 1 has a coaxial ring with an installation ring groove 13. The positioning ring 42 is inserted into the installation ring groove 13, and a pre-tightening rubber pad 6 is inserted into the installation ring groove 13. The positioning ring 42 and the pre-tightening rubber pad 6 are in contact.

[0036] Reference Figure 1 The arc-shaped clamping petals 43 connect the pressure ring 41 and the positioning ring 42. Several arc-shaped clamping petals 43 are evenly distributed along the circumference of the central support column 2 and bend towards the side away from the central support column 2. In this embodiment, six arc-shaped clamping petals 43 are used as an example. An elastic connecting strip 7 made of fatigue-resistant rubber is fixedly connected between two adjacent arc-shaped clamping petals 43.

[0037] Reference Figure 1 During adjustment, the worker can rotate the adjusting block 3 to move it along the axial direction of the central support column 2, thereby changing the opening degree of the multi-lobed clamping ring assembly 4. The arc-shaped clamping lobe 43 is made of spring steel with good elasticity, and the side wall of the arc-shaped clamping lobe 43 facing away from the central support column 2 is fixed with a polytetrafluoroethylene coating, which gives it excellent wear resistance and increases its frictional stability with the yarn. The fatigue-resistant rubber elastic connecting strip 7 can make the arc-shaped clamping lobe 43 maintain a certain elasticity and coordination during opening and closing, so as to ensure that it can effectively clamp the yarn.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The self-locking assembly 5 includes a ratchet disc 51, a pawl 52, a return spring 53, and an unlocking lever 54. The ratchet disc 51 is located on top of the adjusting block 3, and a rotating ring 8 is rotatably connected to the central support column 2. The rotating ring 8 is located near the tray base 1, and several support rods 9 are fixedly connected between the rotating ring 8 and the ratchet disc 51. In this embodiment, four support rods are used as an example. The four support rods 9 are evenly distributed along the circumference of the ratchet disc 51, and the support rods 9 are parallel to the central support column 2 and slide through the adjusting block 3.

[0039] Reference Figure 3 A mounting cavity 21 is provided on the top side wall of the central support column 2. The pawl 52 is hinged to the mounting cavity 21 via a pivot, and the movable end of the pawl 52 is inserted into the inner ring tooth groove of the ratchet disc 51. One end of the return spring 53 is connected to the pawl 52, and the other end is fixed to the inner side wall of the mounting cavity 21. In this embodiment, the return spring 53 is a torsion spring.

[0040] Reference Figure 4 The unlocking lever 54 includes a positioning lever 541, a connecting lever 542, and a connecting rod 543. The positioning lever 541 is slidably mounted on the top wall of the pawl 52 and located near the movable end of the pawl 52. An anti-disengagement block 5411 is fixedly mounted on its end inside the pawl 52. Both the positioning lever 541 and the connecting lever 542 are parallel to the rotation axis of the pawl 52. The connecting rod 543 is fixedly connected to the positioning lever 541 and the connecting lever 542. A locking ball 5421 is fixedly mounted on the end of the connecting lever 542. A connecting hole 22 and a locking groove 23 are provided on the top wall of the central support column 2 and the top wall of the pawl 52, respectively. The connecting lever 542 is inserted into the connecting hole 22, and the locking ball 5421 is locked into the locking groove 23.

[0041] Reference Figure 3 and Figure 4When the insertion rod 542 is inserted into the insertion hole 22 on the top wall of the central support column 2, the pawl 52 disengages from the inner ring tooth groove of the ratchet disc 51, at which point the adjusting block 3 can be adjusted in the opposite direction.

[0042] The implementation principle of an adjustable winding cart pallet according to an embodiment of this application is as follows: In actual use, when it is necessary to fix the yarn bobbin, the worker first rotates the adjusting block 3 according to the inner diameter of the yarn bobbin, so that the adjusting block 3 moves downward along the central support column 2, thereby causing the arc-shaped clamping petals 43 of the multi-lobed clamping ring assembly 4 to open outward until the diameter of the multi-lobed clamping ring assembly 4 matches the diameter of the yarn bobbin. Then, the yarn bobbin is placed on the multi-lobed clamping ring assembly 4 to fix the yarn bobbin. During the adjustment process, under the action of the return spring 53, the movable end of the pawl 52 is always inserted into the inner ring tooth groove of the ratchet disc 51 to prevent the adjusting block 3 from rotating in the opposite direction. This adjustable winding cart pallet effectively solves the problem of insufficient stability of traditional winding cart pallets under actual working conditions by setting a self-locking component 5 between the central support column 2 and the adjusting block 3.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
