Technical Field

[0001] This invention belongs to the field of ring spinning machinery, specifically a semi-decompression cradle for wool spinning. Background Technology

[0002] Wool spinning is the spinning process of processing wool fibers into yarn. Wool fibers are mainly wool, but also include cashmere, rabbit hair, mohair, yak hair and other special animal hairs. Clothing made from wool fabrics has a soft, full and crisp feel.

[0003] During power outages or holidays, to prevent the upper roller from being deformed by pressure, the pressure of the front roller of the cradle is reduced from the working pressure to 40-60% of the working pressure. Before the machine is restarted, the cradle needs to be restored to the working pressure state, and the yarn does not need to be re-spliced.

[0004] The existing semi-release structure of the spring cradle for wool spinning is very complex, difficult to assemble, has poor consistency in semi-release pressure, has many quality problems, is costly, inconvenient to operate, and is prone to complete depressurization of the cradle during the lifting process. Here we provide a semi-release cradle for wool spinning. Summary of the Invention

[0007] Preferably, the positioning rod and the locking plate work together to add a locking point after the four-bar locking mechanism is in the unlocked state.

[0008] Preferably, the frame is internally rotatably connected to a positioning rod, and the rotation of the positioning rod can realize the switching between the normal working pressure and the semi-depressurization function of the cradle.

[0009] Preferably, the angle of the positioning rod can be adjusted manually on a single set, or it can be adjusted simultaneously on the entire vehicle by electric adjustment.

[0010] Preferably, the frame is internally rotatably connected with fixing screws; a fixing screw is installed on one side of the support shaft.

[0011] Preferably, a shaped nut is installed inside the frame, and a shaped nut is installed on one side of the pressure adjusting screw; or a rectangular nut is installed inside the frame, and a rectangular nut is installed on one side of the pressure adjusting screw.

[0012] The beneficial effects of this invention are as follows: This invention provides a wool textile semi-relief rocker, which, through the cooperation of the semi-relief positioning rod and the locking plate, adds a locking point after the four-bar locking mechanism is unlocked. By rotating and adjusting the angle position of the positioning rod, the rocker can switch between normal working pressure and semi-relief function.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-6 This invention provides a semi-relief cradle for wool textiles, comprising a cradle body 1, a handle 2, a cradle shaft 3, a locking plate 4, a handle pin 5, a locking plate pivot pin 6, a frame base shaft 7, a positioning rod 8, a frame base 9, a pressure adjusting screw 13, a support rod shaft 14, a lower roller 15, and an upper roller 16. The handle 2 is mounted on the cradle body 1. The cradle shaft 3 is installed inside the cradle body 1. The frame base 9 is connected to the bottom end of the cradle body 1. The locking plate 4 is connected inside the frame base 9. The handle pin 5 is installed inside the cradle body 1. The locking plate pivot pin 6 is rotatably connected inside the frame base 9. The frame base shaft 7 is installed inside the frame base 9. The positioning rod 8 is provided inside the frame base 9. The support rod shaft 14 is installed inside the frame base 9. Multiple sets of upper rollers 16 are mounted at the bottom end of the cradle body 1. The lower roller 15 is provided at the bottom end of the upper roller 16.

[0024] During operation, when the spinning mill's machines are out of power or closed for holidays, to prevent the upper roller from being deformed by pressure, the pressure on the front roller of the cradle is reduced from the working pressure to 40-60% of the working pressure. Before the machine is restarted, the cradle needs to be restored to the working pressure state, and the yarn does not need to be re-spliced. The existing semi-release structure of the spring cradle for wool spinning is very complex, difficult to assemble, has poor consistency in semi-release pressure, has many quality problems, is costly, inconvenient to operate, and is prone to complete depressurization of the cradle during the lifting process. During operation, the support shaft 14 is fixed on the machine platform, and the cradle... Mounted on the support shaft 14, the frame 9 and the entire rocker arm body 1 are fixed to the support shaft 14. The working height H1 of the rocker arm is adjusted by the adjusting screw 13, and then the rocker arm is fixed by the fixing screw 10. At this time, the rocker arm body 1, handle 2, locking plate 4, and frame 9 form a four-bar locking mechanism. When partial pressure relief is required, first rotate the partial pressure relief positioning rod 8 clockwise by 90°, then lift the handle 2 and rotate it clockwise. Under the limit of the partial pressure relief positioning rod 8, the locking plate 4 cannot rotate counterclockwise. At this time, the rocker arm is in a partial pressure relief state. The working height of the frame changes from H1 to H2. After the cradle is repressurized, handle 2 is pressed down and rotated counterclockwise, rotating the semi-relief positioning rod 8 90° counterclockwise. Then, handle 2 is lifted, and the locking plate 4 is no longer in contact with the positioning rod 8. Handle 2 continues to rotate clockwise, and the cradle will automatically unlock and enter the depressurized state. This realizes the switching between cradle pressurization, semi-relief, and depressurization functions. 15 and 16 work together for wool textile processing. During operation, through the cooperation of the semi-relief positioning rod 8 and the locking plate 4, an additional lock is added after the four-bar locking mechanism is unlocked. The dead point, by rotating and adjusting the angle of the positioning rod 8, achieves the switching between normal working pressure and semi-relaxation function of the cradle. Points A and B are the rotation centers of the frame body bc and the locking plate e, point C is the contact rotation center of the handle a and the locking plate e, and point D is the rotation center of the handle a. Under pressure, the cradle body bc rotates clockwise around point A, and the handle a also rotates clockwise around point A. Because it is in contact with the locking plate e at point C, the combination of the frame body bc and the handle a cannot rotate around point A to cross the BD dead point, and remains in a stable locked state. Figure 2 When partial pressure relief is required, first rotate the partial pressure relief positioning rod 8 90° clockwise, then lift the handle a and rotate it clockwise around point D, so that the combination of frame body bc and handle a rotates around point A past the dead point BD. At the same time, under the action of the positioning rod 8, the locking piece e rotates to... Figure 3 The position stops, thus entering a semi-relief state. After repressurizing the cradle, press down handle a and rotate it counter-clockwise, rotating the semi-relief positioning rod 8 90° counter-clockwise. Then, lift handle a and rotate it clockwise around point D, causing the combination of frame body bc and handle a to rotate around point A past the dead point BD. Continue lifting handle a until... Figure 4 The position is stopped, thus relieving pressure on the cradle.

[0025] Furthermore, the cooperation between the positioning rod 8 and the locking plate 4 adds a locking point after the four-bar locking mechanism is in the unlocked state.

[0026] During operation, the semi-relief positioning rod 8 and the locking plate 4 work together to add a locking point after the four-bar locking mechanism is unlocked. Rotating the positioning rod 8 adjusts the angle, achieving the switch between normal operating pressure and semi-relief function for the rocker arm. Points A and B are the rotation centers of the frame body bc and the locking plate e, point C is the contact rotation center between the handle a and the locking plate e, and point D is the rotation center of the handle a. Under pressure, the rocker arm body bc rotates clockwise around point A, and the handle a also rotates clockwise around point A. Because it contacts the locking plate e at point C, the assembly of the frame body bc and the handle a cannot rotate around point A past the BD dead point, remaining in a stable locked state. Figure 2 When partial pressure relief is required, first rotate the partial pressure relief positioning rod 8 90° clockwise, then lift the handle a and rotate it clockwise around point D, so that the combination of frame body bc and handle a rotates around point A past the dead point BD. At the same time, under the action of the positioning rod 8, the locking piece e rotates to... Figure 3 The position stops, thus entering a semi-relief state. After repressurizing the cradle, press down handle a and rotate it counter-clockwise, rotating the semi-relief positioning rod 8 90° counter-clockwise. Then, lift handle a and rotate it clockwise around point D, causing the combination of frame body bc and handle a to rotate around point A past the dead point BD. Continue lifting handle a until... Figure 4 The position is stopped, thus relieving pressure on the cradle.

[0027] Furthermore, the frame 9 is internally rotatably connected to a positioning rod 8, and the rotation of the positioning rod 8 can realize the switching between the normal working pressure and the semi-depressurization function of the cradle.

[0028] During operation, through the cooperation of the semi-relief positioning rod 8 and the locking plate 4, an additional locking point is added after the four-bar locking mechanism is unlocked. The angle position of the positioning rod 8 is adjusted by rotation to realize the conversion between the normal working pressure and the semi-relief function of the cradle. Points A and B are the rotation centers of the frame bc and the locking plate e, point C is the contact rotation center of the handle a and the locking plate e, and point D is the rotation center of the handle a.

[0029] Furthermore, the angle position of the positioning rod 8 can be adjusted manually on a single set, or it can be adjusted simultaneously by electric adjustment of the entire vehicle.

[0030] During operation, under pressure, the rocker arm bc rotates clockwise around point A, and the handle a also rotates clockwise around point A. Because it contacts the locking plate e at point C, the assembly of the rocker arm bc and handle a cannot rotate around point A past the dead point BD, remaining in a stable locked state. Figure 2When partial pressure relief is required, first rotate the partial pressure relief positioning rod 8 90° clockwise, then lift the handle a and rotate it clockwise around point D, so that the combination of frame body bc and handle a rotates around point A past the dead point BD. At the same time, under the action of the positioning rod 8, the locking piece e rotates to... Figure 3 The position stops, thus entering a semi-relief state. After repressurizing the cradle, press down handle a and rotate it counter-clockwise, rotating the semi-relief positioning rod 8 90° counter-clockwise. Then, lift handle a and rotate it clockwise around point D, causing the combination of frame body bc and handle a to rotate around point A past the dead point BD. Continue lifting handle a until... Figure 4 The position is stopped, thus relieving pressure on the cradle.

[0031] Furthermore, a fixing screw 10 is rotatably connected inside the frame 9; a fixing screw 10 is installed on one side of the support shaft 14.

[0032] During operation, the support shaft 14 is fixed on the machine base, and the rocker arm is installed on the support shaft 14. The working height H1 of the rocker arm is adjusted by the adjusting screw 13, and then the rocker arm is fixed by the fixing screw 10. At this time, the rocker arm body 1, handle 2, locking plate 4, and frame 9 form a four-bar locking mechanism.

[0033] Furthermore, a shaped nut 12 is installed inside the bracket 9, and a shaped nut 12 is installed on one side of the pressure adjusting screw 13; a rectangular nut 11 is installed inside the bracket 9, and a rectangular nut 11 is installed on one side of the pressure adjusting screw 13.

[0034] During operation, the working height H1 of the cradle is adjusted by adjusting the pressure screw 13, and then the cradle is fixed by fixing screw 10. The fixing screw 10 is rotatably connected inside the rectangular nut 11, and the position of the fixing screw 10 is fixed by the rectangular nut 11. The irregular nut 12 is threadedly connected to the adjusting screw 13, and the position of the adjusting screw 13 can be limited by the irregular nut 12.

[0035] Working principle: During power outages or holidays in spinning mills, to prevent the upper roller from deforming under pressure, the pressure on the front roller of the cradle is reduced from the working pressure to 40-60% of the working pressure. Before restarting the machine, the cradle needs to be restored to the working pressure state, and the yarn does not need to be re-spliced. The existing semi-release structure of the spring cradle in wool spinning is very complex, difficult to assemble, has poor consistency in semi-release pressure, has many quality problems, is costly, inconvenient to operate, and is prone to complete pressure release of the cradle during the lifting process. During operation, the support shaft 14 is fixed on the machine base. The rocker arm remains stationary, mounted on the support shaft 14. The working height H1 of the rocker arm is adjusted using the adjusting screw 13, and then fixed by the fixing screw 10. At this point, the rocker arm body 1, handle 2, locking plate 4, and frame 9 form a four-bar locking mechanism. When partial pressure release is required, first rotate the partial pressure release positioning rod 8 clockwise by 90°, then lift the handle 2 and rotate it clockwise. Under the limit of the partial pressure release positioning rod 8, the locking plate 4 cannot rotate counterclockwise. At this time, the rocker arm is in a partial pressure release state, and the working height of the rocker arm changes from H1 to... H2, after repressurizing the cradle, press down handle 2 and rotate it counterclockwise. Rotate the semi-relief positioning rod 8 counterclockwise by 90°. Then lift handle 2. The locking plate 4 is no longer in contact with the positioning rod 8. Continue to rotate handle 2 clockwise. The cradle will automatically unlock and enter the depressurized state. This realizes the switching between cradle pressurization, semi-relief, and depressurization functions. 15 and 16 work together for wool textile processing. During operation, through the cooperation of the semi-relief positioning rod 8 and the locking plate 4, an additional locking point is added after the four-bar locking mechanism is unlocked. Rotation Adjusting the angle of positioning rod 8 achieves the switching between normal working pressure and semi-relaxation function of the rocker arm. Points A and B are the rotation centers of the frame body bc and locking plate e, point C is the contact rotation center of handle a and locking plate e, and point D is the rotation center of handle a. Under pressure, the rocker arm body bc rotates clockwise around point A, and handle a also rotates clockwise around point A. Due to its contact with locking plate e at point C, the combination of frame body bc and handle a cannot rotate around point A past the dead point BD, and remains in a stable locked state. Figure 2 When partial pressure relief is required, first rotate the partial pressure relief positioning rod 8 90° clockwise, then lift the handle a and rotate it clockwise around point D, so that the combination of frame body bc and handle a rotates around point A past the dead point BD. At the same time, under the action of the positioning rod 8, the locking piece e rotates to... Figure 3 The position stops, thus entering a semi-relief state. After repressurizing the cradle, press down handle a and rotate it counter-clockwise, rotating the semi-relief positioning rod 8 90° counter-clockwise. Then, lift handle a and rotate it clockwise around point D, causing the combination of frame body bc and handle a to rotate around point A past the dead point BD. Continue lifting handle a until... Figure 4 The position is stopped, thus relieving pressure on the cradle.
