Description

Technical Field

[0001] This utility model belongs to the field of post-dehydration and post-processing technology of yarn package, specifically relating to an adjustable yarn support rod stabilizing device for a dewatering machine. Background Technology

[0002] In the textile industry, the dewatering process of yarn packages has been widely automated to achieve efficient and continuous operation. Automatic dewatering machines are typically equipped with multiple yarn carriers, which are gripped and placed by robotic arms to automatically load and unload yarn packages, followed by high-speed dewatering. To accommodate the mechanical vibrations and positional deviations generated during dynamic loading and unloading, the yarn carriers are generally connected to the equipment base via elastic connection mechanisms. Common designs employ springs or similar elastic elements, allowing the carriers to swing within a certain angle and range. This buffers the impact from the robotic arms placing the yarn packages and facilitates system stability during dewatering start-up and shutdown phases.

[0003] However, in actual continuous production, due to the frequent operation of the robotic arm and the continuous excitation from the high-speed operation of the dewatering machine, the yarn carrier is in a state of high-frequency, large-amplitude oscillation for a long time. This makes the spring mechanism used in its support structure prone to fatigue failure, plastic deformation, or loosening of the fixed end. Once the spring mechanism has the above problems, the yarn carrier cannot accurately return to the preset identifiable initial position of the robotic arm, resulting in positional deviation or posture inaccuracy. Although this deviation is sometimes small, it will directly lead to the subsequent failure of the robotic arm to grasp, the incomplete loading of the yarn package, and thus trigger the equipment sensor alarm, or even cause the entire machine to automatically stop. Such failures not only interrupt the continuous operation of the production line, but also increase the frequency of manual intervention, seriously affecting the stability and production efficiency of the entire automated production system.

[0004] In existing technological structures, the spring mechanism is typically integrated with the yarn-carrying rod support or base. If elasticity fails or positional drift occurs, it often requires complete disassembly, replacement, or cumbersome on-site adjustments of the relevant components. This maintenance process is time-consuming and requires the involvement of specialized technicians. This increases equipment maintenance costs, reduces effective operating time, and significantly restricts overall equipment utilization. Therefore, the existing elastic connection structure of the yarn-carrying rod in dewatering machines still needs further improvement and optimization in terms of long-term reliability, ease of maintenance, and positional reset accuracy. Utility Model Content

[0005] This invention addresses the technical problems of existing yarn rod spring reset mechanisms in dewatering machines, such as easy failure due to fatigue, inaccurate reset, and inconvenient maintenance and adjustment, by providing an adjustable yarn rod stabilizing device for dewatering machines.

[0006] To solve the above problems, the technical solution of this utility model is:

[0007] The adjustable yarn carrier stabilizing device for a dewatering machine described in this utility model is installed between the yarn carrier and the base of a packaged yarn dewatering machine. It includes a fixed sleeve and a connecting bolt. The lower end of the connecting bolt is fixedly connected to the base, and the upper screw portion extends into the inner cavity of the fixed sleeve. A compression spring is fitted onto the connecting bolt. The inner wall of the fixed sleeve has at least one guide groove along the axial direction. A guide nut is threaded onto the screw portion of the connecting bolt located in the inner cavity of the fixed sleeve. The compression spring is located between the guide nut and the bottom of the inner layer of the fixed sleeve. The outer periphery of the guide nut has a guide portion that mates with the guide groove on the inner wall of the fixed sleeve, allowing the guide nut to slide axially along the guide groove without rotating relative to it. A pressure cap is fixedly connected to the top end face of the fixed sleeve.

[0008] The base is typically a slider that drives its movement and is part of the dehydrator's drag arm.

[0009] The adjustable yarn carrier stabilizing device is nested inside the cavity of the yarn carrier.

[0010] The pressure cap is provided with a telescopic protrusion, and the yarn carrier rod is provided with a limiting hole at the corresponding position.

[0011] The connecting bolt passes through the base and connects to the fixing sleeve and guide nut.

[0012] Preferably, the base is provided with a mating hole that matches the lower bolt head of the connecting bolt. The mating hole allows the lower bolt head of the connecting bolt to be fixed, preventing the connecting bolt from rotating when adjusting the initial compression of the compression spring. If the lower bolt head of the connecting bolt is not fixed, a wrench must be used to prevent it from rotating when adjusting the initial compression of the compression spring, or the bolt head of the connecting bolt must be rotated directly to adjust the initial compression.

[0013] The gland is connected to the fixed sleeve by fixing bolts. The gland is installed and pressed into the top port of the fixed sleeve by multiple fixing bolts, which is used to close the fixed sleeve, provide an upper support point for the compression spring, and prevent internal components from coming out.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1) This utility model strictly limits the movement trajectory of the yarn carrier rod through the precise cooperation of the guide groove and the guide nut, ensuring that it can only translate and reset along the preset axial direction, completely avoiding skewing and jamming, and ensuring the absolute consistency of the position of the yarn carrier rod when the robot grabs it each time.

[0016] 2) One of the core innovations of this utility model lies in providing a convenient online adjustment function. When the compression spring fatigues and the restoring force weakens after long-term use, maintenance personnel do not need to disassemble the entire device. Simply keep the bolt head at the bottom of the connecting bolt fixed to prevent rotation, and then rotate the fixing sleeve located on the upper part of the base. This allows the guide nut to move axially along the connecting bolt while remaining stationary inside the fixing sleeve, thereby changing the initial compression of the compression spring and easily restoring the restoring force to the required level. This greatly extends the service life of the device and reduces the need for spare parts replacement.

[0017] 3) All key components of this invention are integrated into the fixing sleeve inside the yarn carrier rod, with only connecting bolts and pressure caps visible on the outside. The structure is very compact and has strong anti-interference capabilities. The mechanical connection method is reliable, with no complex electrical components, making it suitable for humid and vibrating dewatering machine environments.

[0018] 4) The performance of this invention can be restored with simple adjustments, avoiding major downtime and replacement caused by minor problems, significantly reducing maintenance costs and time, and improving the overall efficiency and equipment utilization of the entire automated dehydration system.

[0026] The present invention will be explained in detail below with reference to the embodiments.

[0027] Example

[0028] like Figure 1-5 As shown, the adjustable yarn carrier stabilizing device for the dewatering machine is installed between the yarn carrier 8 and the base 7 of the yarn dewatering machine. It includes a fixing sleeve 5 and a connecting bolt 6. The lower end of the connecting bolt 6 is fixedly connected to the base 7, and the upper screw part extends into the inner cavity of the fixing sleeve 5. A compression spring 4 is sleeved on the connecting bolt 6. The inner wall of the fixing sleeve 5 has two guide grooves 501 symmetrically opened along the axial direction. The threaded connection of the guide nut 3 is on the screw part of the connecting bolt 6 located in the inner cavity of the fixing sleeve 5. The compression spring 4 is located between the guide nut 3 and the bottom of the inner layer of the fixing sleeve 5. The outer periphery of the guide nut 3 has a guide part that cooperates with the guide groove 501 of the inner wall of the fixing sleeve 5, so that the guide nut 3 can slide along the axial direction of the guide groove 501 but cannot rotate relative to it. A pressure cap 2 is fixedly connected to the top end face of the fixing sleeve 5.

[0029] The base 7 is a slider that drives its movement and is part of the dehydrator's drag arm.

[0030] The adjustable yarn carrier stabilizing device is nested inside the cavity of the yarn carrier 8.

[0031] The pressure cap 2 is provided with a telescopic protrusion 201, and the yarn carrier 8 has a limiting hole 801 at the corresponding position. The telescopic protrusion 201 has a built-in spring, which can be compressed and popped out.

[0032] During assembly, the telescopic protrusion 201 on the pressure cap 2 is first pre-compressed and inserted into the inner cavity of the yarn carrier 8. Then, it is aligned with the position of the limiting hole 801. When the adjustable yarn carrier stabilizing device enters to the depth of the limiting hole 801 of the yarn carrier 8, the telescopic protrusion 201 will pop out from the two limiting holes 801 at the corresponding position of the limiting hole 801, which can prevent the yarn carrier 8 from rotating and detaching.

[0033] The connecting bolt 6 passes through the base 7 and connects to the fixing sleeve 5 and the guide nut 3.

[0034] The base 7 is provided with a mating hole 701 that matches the lower bolt head of the connecting bolt 6. The lower bolt head of the connecting bolt 6 is a hexagonal head, and the mating hole 701 can fix the lower bolt head, preventing the connecting bolt 6 from rotating when adjusting the initial compression of the compression spring 4.

[0035] The pressure cap 2 is connected to the fixing sleeve 5 by fixing bolts 1. The pressure cap 2 is installed and pressed into the top port of the fixing sleeve 5 by four fixing bolts 1, which is used to close the fixing sleeve 5, provide an upper support point for the compression spring 4, and prevent internal components from coming out.

[0036] Working principle and adjustment process:

[0037] Normal operation: When the robotic arm loads yarn packages or the dewatering machine starts, the yarn-carrying rod 8 may be subjected to lateral forces. At this time, the yarn-carrying rod 8 causes the fixing sleeve 5 to have a slight axial offset or tilting tendency relative to the connecting bolt 6. This tendency is converted into compression or tension on the compression spring 4. The compression spring 4 absorbs energy and deforms. When the external force disappears, the restoring force of the compression spring 4 pushes the guide nut 3 to slide downward along the guide groove 501, thereby driving the fixing sleeve 5 and the entire yarn-carrying rod 8 to accurately return to the initial vertical center position.

[0038] Adjustment Process: When the yarn carrier 8 is found to be slow to return to its original position or unable to return to center completely, indicating fatigue of the compression spring 4, adjustment is performed. Due to the locking action between the bolt head of the connecting bolt 6 and the mating hole 701, simply keep the base 7 stationary and rotate the upper fixing sleeve 5. Because the guide nut 3 is restricted from rotation by the guide groove 501 within the fixing sleeve 5, it will move upward or downward along the thread of the connecting bolt 6. Upward movement increases the compression of the compression spring 4, thereby increasing the return force; downward movement decreases the preload. After adjusting to the appropriate force, the device will restore its original performance.
