Description

Technical Field

[0001] This disclosure belongs to the field of spinning cradle technology, specifically relating to a semi-unscrewing locking mechanism for a spinning cradle with a self-lubricating and dustproof structure. Background Technology

[0002] The spinning cradle is the core pressure component of the drafting device of the spinning frame. It is mainly used to provide stable and controllable pressure to the rollers, so that the rollers fit tightly together to form a gripping jaw, thereby drafting and twisting the roving sliver to produce fine yarn.

[0003] The existing semi-unscrew locking mechanism of the spinning frame has some shortcomings in use: the force transmission path of the semi-unscrew locking mechanism is not smooth, and uneven force on the rollers is likely to occur during the unscrew process. Some rollers are still under high pressure, which cannot effectively achieve the purpose of protecting the rollers during semi-unscrew. In addition, the locking and positioning structure after unscrewing has poor anti-loosening performance. Affected by the vibration of the spinning machine, the locking position is prone to shift, which leads to changes in the fit of the rollers.

[0004] To address these issues, those skilled in the art have proposed a semi-unloading locking mechanism for a yarn cradle with a self-lubricating and dust-proof structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a semi-unscrew locking mechanism for a yarn cradle with a self-lubricating and dustproof structure, which solves the problem in existing technologies where uneven force on the rollers easily occurs during the unscrewing process, and some rollers remain under high pressure.

[0006] The objective of this disclosure can be achieved through the following technical solutions:

[0007] A semi-unloading locking mechanism for a yarn cradle with a self-lubricating and dustproof structure includes a cradle body, on which a handle and a yarn guide groove are provided, and further includes:

[0008] A leaf spring mechanism connected to the cradle body, the leaf spring mechanism being used to provide elastic pressure to the roller;

[0009] The front grip, auxiliary grip, and rear grip are designed to cooperate with the rocker arm and leaf spring mechanism. The front grip, auxiliary grip, and rear grip are respectively used to install roller one, auxiliary roller, and roller two, so that each roller forms a gripping jaw.

[0010] The pressure relief mechanism connected to the cradle body is a semi-pressure relief locking actuator used to drive the cradle body to switch between pressurized and semi-pressure relief states and lock positions, thereby enabling the gripping seats and rollers to move.

[0011] Preferably, it also includes an adjustment mechanism, which includes a main adjustment roller installed at the end of the cradle body away from the yarn guide groove, a secondary adjustment roller provided at one end of the main adjustment roller, and an adjustment shaft one and an adjustment shaft two respectively inserted between the main adjustment roller and the secondary adjustment roller.

[0012] Preferably, the leaf spring mechanism includes a fixed plate, an adjusting frame, and a pressure adjusting column. The fixed plate is fixedly connected to the rocker body, the adjusting frame is fixedly connected to the fixed plate, and the pressure adjusting column is slidably connected to the adjusting frame. One end of the pressure adjusting column abuts against the front grip, the auxiliary grip, and the rear grip, respectively.

[0013] Preferably, the front grip is provided with a first drive assembly, the auxiliary grip is provided with a second drive assembly, and the rear grip is provided with a third drive assembly. The first drive assembly, the second drive assembly, and the third drive assembly are respectively connected to the first roller, the auxiliary roller, and the second roller in a transmission connection.

[0014] Preferably, the pressure relief mechanism includes connecting plates fixed on both sides of the top of the first drive assembly, the second drive assembly, and the third drive assembly. A housing is provided on the outer wall of the connecting plate, and a motor is provided inside the housing. A sleeve plate is sleeved on the outer wall of the motor output shaft, and a pressure relief component is provided on the outer wall of the sleeve plate.

[0015] Preferably, the pressure relief assembly includes an arrow plate fixed on the outer wall of the sleeve plate. Multiple compression buffer cylinders are fixed on the outer wall of the arrow plate near the output shafts of drive assembly one, drive assembly two, and drive assembly three. A pressure plate is installed at one end of each compression buffer cylinder.

[0016] Preferably, the compression buffer cylinder is filled with lubricating oil, and an oil outlet pipe is installed on the outer wall of the compression buffer cylinder near the output shafts of drive assembly one, drive assembly two, and drive assembly three.

[0017] Preferably, a screw is sleeved at one end of the motor output shaft, a threaded sleeve is screwed at one end of the screw, and one end of the threaded sleeve is respectively attached to the outer wall of the first roller, the auxiliary roller, and the second roller.

[0018] Preferably, it also includes a dustproof mechanism, which is disposed above the first roller, the auxiliary roller, and the second roller.

[0019] Preferably, the dustproof mechanism includes a dust baffle plate installed on the outer wall of the cradle body, and an electrostatic adsorption plate is installed on the bottom outer wall of the dust baffle plate.

[0020] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0021] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0022] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0023] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0024] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0025] The beneficial effects of this disclosure are:

[0026] By setting a pressure relief mechanism connected to the cradle body as a semi-pressure relief locking actuator, the cradle body can be directly driven to move each gripping seat and roller synchronously, realizing a smooth switching between pressurization and semi-pressure relief states and reliable position locking. This effectively optimizes the force transmission path and solves the problems of uneven force on the rollers and continuous high pressure on some rollers during pressure relief in traditional mechanisms. It achieves synchronous and uniform pressure relief of each roller, effectively protecting the rollers and preventing them from being deformed by long-term pressure. At the same time, it ensures the stability of the semi-pressure relief position locking, resists positional deviation caused by equipment working vibration, ensures the stable cooperation state of the gripping jaws, and guarantees the continuity and stability of fine yarn drafting processing.

[0027] By setting up a compression buffer cylinder, the motor drives the sleeve plate to rotate, which in turn drives the arrow plate to rotate. The compression buffer cylinder and the pressure plate press against drive assembly one, drive assembly two, and drive assembly three, thereby locking roller one, auxiliary roller two, and roller two. When pressure needs to be released, the force applied by the motor is reduced. An oil outlet pipe is set at the bottom of the compression buffer cylinder. When lubrication of the components is required, the force applied by the motor is increased, causing the compression buffer cylinder to be compressed to the bottom oil outlet pipe, and then the lubricating oil inside is discharged, thus lubricating the components.

[0028] One end of the motor output shaft has a screw and a screw sleeve. By the motor reciprocating within a certain angle, the screw sleeve can repeatedly strike roller one, auxiliary roller and roller two, thereby causing the yarn on them to vibrate and shake off the dust on the yarn. Subsequently, the dust is adsorbed by an electrostatic adsorption plate. Attached Figure Description

[0036] The technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present disclosure.

[0037] Those skilled in the art will understand that the expressions relating to direction are used herein for ease of description only and are not intended to be an absolute limitation of a yarn cradle semi-unloading locking mechanism with a self-lubricating and dustproof structure.

[0038] Please refer to Figures 1 to 5 A semi-unloading locking mechanism for a yarn cradle with a self-lubricating and dustproof structure includes a cradle body 1, on which a handle 101 and a yarn guide groove 102 are provided, and further includes:

[0039] The leaf spring mechanism 7 is connected to the cradle body 1 and is used to provide elastic pressure to the roller.

[0040] The front gripping seat 3, auxiliary gripping seat 4, and rear gripping seat 5 cooperate with the rocker body 1 and the leaf spring mechanism 7. The front gripping seat 3, auxiliary gripping seat 4, and rear gripping seat 5 are used to install roller 1 302, auxiliary roller 402, and roller 2 502 respectively, so that each roller forms a gripping jaw.

[0041] The pressure relief mechanism 8 is connected to the cradle body 1. The pressure relief mechanism 8 is a semi-pressure relief locking actuator, which is used to drive the cradle body 1 to drive each grip seat and the roller to achieve the switching of pressure and semi-pressure relief states and position locking.

[0042] With the cradle body 1 as the overall support and installation base, the leaf spring mechanism 7 releases elastic pressure, which is transmitted to the front gripping seat 3, auxiliary gripping seat 4, and rear gripping seat 5 that cooperate with the cradle body 1 and the leaf spring mechanism 7. The three gripping seats transmit the pressure to the roller 1 302, auxiliary roller 402, and roller 2 502 installed on them respectively, so that the rollers cooperate to form a stable gripping jaw. The yarn guide groove 102 on the cradle body 1 accurately guides the roving sliver to the gripping jaw, providing a reliable gripping base for the fine yarn drafting. At this time, the handle 101 on the cradle body 1 is in the pressure locking position, ensuring the stability of the overall mechanism under pressure.

[0043] When the equipment needs to be briefly stopped, the pressure relief mechanism 8, acting as the semi-pressure relief locking actuator, drives the rocker arm 1 to produce a linkage action. The rocker arm 1 synchronously drives the front grip 3, auxiliary grip 4, rear grip 5, and the rollers on each grip to move synchronously, so that the elastic pressure of the leaf spring mechanism 7 is precisely released, and the pressure on each roller is reduced synchronously and evenly, realizing a smooth transition from pressurization to semi-pressure relief. At the same time, the pressure relief mechanism 8 locks the position of the rocker arm 1, so that each grip and roller is stably kept in the semi-pressure relief position, avoiding uneven force on the rollers caused by positional deviation, and effectively protecting each roller to prevent permanent deformation due to long-term high pressure.

[0044] When it is necessary to resume normal spinning operations, the pressure relief mechanism 8 releases the locking of the half-pressure relief position of the cradle body 1, and the leaf spring mechanism 7 releases the elastic pressure again, driving the cradle body 1 to reset the front gripping seat 3, the auxiliary gripping seat 4, the rear gripping seat 5 and each roller. The rollers re-coordinate to form a stable gripping jaw, and the entire mechanism returns to the working state of pressure gripping, meeting the process requirements of yarn drafting.

[0045] Specifically, it also includes an adjustment mechanism 2, which includes a main adjustment roller 201 installed at one end of the cradle body 1 away from the yarn guide groove 102, a secondary adjustment roller 203 provided at one end of the main adjustment roller 201, and an adjustment shaft 1 202 and an adjustment shaft 204 respectively inserted between the main adjustment roller 201 and the secondary adjustment roller 203.

[0046] The tilt angle and working distance of the cradle body 1 can be adjusted by the main adjusting roller 201 and the auxiliary adjusting roller 203.

[0047] Furthermore, the leaf spring mechanism 7 includes a fixed plate 701, an adjusting frame 702, and a pressure adjusting column 703. The fixed plate 701 is fixedly connected to the rocker body 1, the adjusting frame 702 is fixedly connected to the fixed plate 701, and the pressure adjusting column 703 is slidably connected to the adjusting frame 702. One end of the pressure adjusting column 703 abuts against the front grip 3, the auxiliary grip 4, and the rear grip 5, respectively.

[0048] The elastic pressure generated by the leaf spring mechanism 7 is transmitted one-to-one to the corresponding gripping seat through the axial pushing action of the pressure adjusting column 703. Then, each gripping seat transmits the pressure evenly to the installed rollers, so that each roller obtains a stable and suitable pressure, thereby forming a gripping jaw with uniform pressure.

[0049] It should be noted that the front grip 3 is provided with a drive assembly 301, the auxiliary grip 4 is provided with a drive assembly 401, and the rear grip 5 is provided with a drive assembly 501. The drive assembly 301, the drive assembly 401, and the drive assembly 501 are respectively connected to the roller 302, the auxiliary roller 402, and the roller 502 for transmission.

[0050] Furthermore, the pressure relief mechanism 8 includes connecting plates 801 fixed on both sides of the top of drive assembly 1 301, drive assembly 2 401 and drive assembly 3 501. A housing 802 is provided on the outer wall of the connecting plate 801. A motor is provided inside the housing 802. A sleeve plate 803 is sleeved on the outer wall of the motor output shaft. A pressure relief component is provided on the outer wall of the sleeve plate 803.

[0051] Adjust the corresponding drive components 301, 401, and 501 by adjusting the pressure relief components.

[0052] Specifically, the pressure relief assembly includes an arrow plate 805 fixed on the outer wall of the sleeve plate 803. Multiple compression buffer cylinders 806 are fixed on the outer wall of the arrow plate 805 near the output shafts of drive assembly 1 301, drive assembly 2 401 and drive assembly 3 501. A pressure plate 808 is installed at one end of the compression buffer cylinder 806.

[0053] The compression buffer cylinder 806 and the pressure plate 808 press against the output shafts of drive assembly 1 301, drive assembly 2 401 and drive assembly 3 501, thereby controlling their movement.

[0054] Furthermore, the compression buffer cylinder 806 is filled with lubricating oil, and an oil outlet pipe 807 is installed on the outer wall of the compression buffer cylinder 806 near the output shaft of drive assembly 1 301, drive assembly 2 401 and drive assembly 3 501.

[0055] When lubrication of the components is required, the force applied by the motor is increased, causing the compression buffer cylinder 806 to be compressed to the bottom oil outlet pipe 807, and then the lubricating oil inside is discharged, thus lubricating the components.

[0056] Specifically, a screw is sleeved at one end of the motor output shaft, and a threaded sleeve 804 is screwed at one end of the screw. One end of the threaded sleeve 804 is respectively attached to the outer wall of roller 1 302, auxiliary roller 402, and roller 2 502.

[0057] By having the motor reciprocate within a certain angle, the screw sleeve 804 can reciprocate to strike the roller 302, the auxiliary roller 402, and the roller 502, thereby causing the yarn on it to vibrate and shake off the dust.

[0058] Specifically, it also includes a dustproof mechanism 6, which is located above roller 1 302, auxiliary roller 402, and roller 2 502.

[0059] Furthermore, the dustproof mechanism 6 includes a dust baffle 601 installed on the outer wall of the cradle body 1, and an electrostatic adsorption plate 602 is installed on the bottom outer wall of the dust baffle 601.

[0060] The shaken-off dust can be absorbed by the electrostatic adsorption plate 602.

[0061] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates the semi-unloading and locking mechanism for a yarn cradle with a self-lubricating and dustproof structure provided by the present invention.

[0062] In use, the fixed plate 701 of the leaf spring mechanism 7 is fixedly connected to the rocker body 1. The elastic pressure is precisely transmitted to the front gripping seat 3, the auxiliary gripping seat 4, and the rear gripping seat 5 through the pressure adjusting column 703 guided by the adjusting frame 702. The three gripping seats transmit the pressure to the installed roller 1 302, auxiliary roller 402, and roller 2 502 respectively, so that each roller forms a stable gripping jaw. The yarn guide groove 102 on the rocker body 1 precisely guides the roving sliver to the jaw, completing the gripping basis for yarn drafting.

[0063] The pressure relief mechanism 8 drives the rocker body 1 to move synchronously, causing each grip and corresponding roller to move synchronously. The elastic pressure of the leaf spring mechanism 7 is precisely released, and the pressure adjusting column 703 is finely adjusted in conjunction with the grip, so that the pressure on each roller is reduced synchronously and evenly, achieving a smooth switch from pressurization to semi-pressure relief. At the same time, the pressure relief mechanism 8 locks the position of the rocker body 1, so that each grip and roller is stably kept in a semi-pressure relief state, avoiding uneven force that could cause the roller to deform.

[0064] The pressure relief mechanism 8 releases the locking of the cradle body 1, the leaf spring mechanism 7 restores elastic pressure, and the pressure is transmitted back to each gripping seat through the pressure regulating column 703, which drives each roller to reset and form a stable gripping jaw again. The cradle body 1 and each component return to the initial working state, and the entire mechanism resumes pressure gripping operation to meet the process requirements of continuous yarn drafting.
