Description

Technical Field

[0001] The invention relates to the technical field of spinning frame colony adjustment, and more specifically to a height calibration device for spinning frame colony adjustment. Background Art

[0002] The spinning frame refers to a spinning machine that stretches, twists, and winds semi-finished roving or slivers into spun yarn bobbins during the spinning process. The slivers are stretched and twisted on the roving frame to form roving, the combing machine combs the fibers to form combed slivers, the pin combing machine combines the slivers, and the pin row stretching improves the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. Among them, the collective yarn dropping device on the spinning frame refers to a device that grabs and loosens the tubes from the spinning frame, automatically removes all full tubes of yarn, and replaces them with empty tubes and produces a good head. Among them, the lifting arm drives the tube grabber to move, mainly the lifting arm descends from the zero position to the lowest position to grab the empty tube, then raises the empty tube to the top of the storage head to loosen the tube, then rises to the top of the spindle to grab the full yarn tube, and then descends to put the full yarn tube into the conveyor plate.

[0003] During long-term use, the height of the gripper position of the lifting arm will shift, so the gripper at the lifting arm of the collective doffing position of the spinning frame needs to be regularly calibrated. Usually, a height gauge is used to compare the gripper height, and then the gripper height is adjusted by adjusting the main arm on the gripper transmission shaft. However, during operation, one person is required to hold the height gauge so that the two detection heads are aligned with the gripper frame and the auxiliary arm, and the other person is required to adjust the height. It is inconvenient for two people to operate, time-consuming and labor-intensive, and the adjustment efficiency is low. In addition, the height gauge is unstable during comparison, and the height adjustment cannot be controlled more accurately. It is often adjusted too high or too low, and the adjustment effect is not good.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-4A height calibration device for adjusting the collection of a spinning frame comprises a spinning frame body 1, on which a collective doffing device 2 and a bottom plate 3 are arranged, the collective doffing device 2 also comprises a lifting arm, a yarn grabber and a gripper transmission shaft, the yarn grabber is provided with a gripping beam 203, on which a gripper frame 201 is arranged, the lifting arm comprises a main arm 204 and an auxiliary arm 202, one end of the main arm 204 of the lifting arm is hinged to the gripper transmission shaft, and the other end is hinged to the gripper frame 201, one end of the auxiliary arm 202 is hinged to the gripper transmission shaft, and the other end is rotatably connected to the main arm 204.

[0044] It also includes: a detection plate 4, which is movably arranged on the bottom plate 3, and a first detection head 5 and a second detection head 6 are arranged on the detection plate 4; an adjustment mechanism 7, which is arranged on the detection plate 4 and is used to drive the second detection head 6 to move up and down; an upper baffle 10 and a lower baffle 11, which are movably arranged on the detection plate 4, and both the upper baffle 10 and the lower baffle 11 are provided with a limiting mechanism 9, which is used to cooperate with the adjustment mechanism 7 to fix the upper baffle 10 and the lower baffle 11.

[0045] When in use, firstly, the second detection head 6 is driven to move up and down by operating the adjustment mechanism 7 to change the height of the second detection head 6, thereby adjusting the distance between the second detection head 6 and the first detection head 5, so that the distance is the correct distance between the gripping frame 201 and the auxiliary arm 202. After the adjustment is completed, the detection stand 4 is moved along the bottom plate 3, and after the detection stand 4 is moved to the designated position where the gripping frame 201 needs to be adjusted, the first detection head 5 on the detection stand 4 is aligned with the rotation center position of the auxiliary arm 202, and then the position where the second detection head 6 is aligned is observed. If the rotation center position of the gripping frame 201 is above / below the second detection head 6, it means that the gripping frame 201 is too high / low at this time, and the gripping frame 201 needs to be adjusted downward / upward. At this time, it is necessary to loosen the fixing screw of the main arm 204 on the grab transmission shaft, and then slide the main arm 204 along the grab transmission shaft. At this time, the main arm 204 will drive the grab frame 201 and the gripping beam 203 to move up or down. At this time, the position of the grab frame 201 can be adjusted to align the rotation center position of the main arm 204 with the second detection head 6. After the adjustment is completed, the main arm 204 on the transmission shaft is fixed to complete the calibration operation. At this time, one person can complete the entire process, avoiding the inconvenience of two people operating at present, saving time and effort, greatly improving work efficiency, and avoiding errors caused by shaking when one person holds the handle at present. The use effect is good and the practicability is strong.

[0046] At the same time, before adjusting the height of the grab frame 201, the upper baffle 10 and the lower baffle 11 are respectively located above and below the gripping beam 203. When adjusting the height of the grab frame 201, when the heights of the grab frame 201 and the gripping beam 203 are too high, they need to be lowered. Before this, the lower baffle 11 is moved upward along the detection vertical plate 4. After moving to the specified position, the lower baffle 11 is fixed at this position through the cooperation of the limiting mechanism 9 and the adjusting mechanism 7. Figure 1-2 and Figure 4 As shown, the lower baffle 11 is in a calibrated position at this time, that is, when the grab frame 201 and the gripping beam 203 are subsequently adjusted down, when the bottom of the gripping beam 203 contacts the lower baffle 11, it will be blocked and cannot move down, and this indicates that the gripping beam 203 and the grab frame 201 have been adjusted to the correct position; vice versa, when the height of the grab frame 201 and the gripping beam 203 is too low, they need to be adjusted up, then after the upper baffle 10 is moved down to the specified position and fixed, the upper end of the gripping beam 203 will be blocked by the upper baffle 10, indicating that the calibration is in place. In summary, when adjusting the height position of the grab frame 201 and the gripping beam 203, there is no need for the staff to always observe the relative height position of the grab frame 201 and the second detection head 6. As long as the gripping beam 203 is limited by the upper baffle 10 or the lower baffle 11, it means that the adjustment is completed. The operation is simple and saves the time and energy wasted on repeated fine-tuning, which greatly improves the efficiency of height calibration. The calibration is stable and accurate, which greatly avoids the situation of over-adjustment or over-low adjustment for a long time, and the adjustment effect is good.

[0047] In this embodiment, preferably, please refer to Figure 3-4 , the detection plate 4 is provided with an adjustment slot 12, and the adjustment mechanism 7 includes: a screw rod 71, which is rotatably connected to the adjustment slot 12 through a bearing, and the top of the screw rod 71 extends to the outside of the detection plate 4 and is provided with a turntable 72; a sleeve 73, which is threadedly connected to the screw rod 71 and slides with the inner wall of the adjustment slot 12, and the second detection head 6 is connected to one end of the sleeve 73. The screw rod 71 is driven to rotate by rotating the turntable 72, and the screw rod 71 will drive the sleeve 73 to move up and down along the inner wall of the adjustment slot 12 when the screw rod 71 rotates. At this time, the sleeve 73 will drive the second detection head 6 to move up and down, and the height position of the second detection head 6 can be adjusted.

[0048] In this embodiment, preferably, please refer to Figure 6The turntable 72 is provided with a first arc groove 17 and a second arc groove 18, and a fixing screw hole 19 is provided on the top of the detection stand 4. The first arc groove 17 and the second arc groove 18 are provided with screws 20, and the position of the turntable 72 is fixed by cooperating with the fixing screw hole 19. When the turntable 72 drives the screw rod 71 to rotate so that the sleeve 73 moves to the specified position, the bottom of the screw rod 20 on the first arc groove 17 or the second arc groove 18 is screwed into the fixing screw hole 19, so that the turntable 72 can be fixed, thereby avoiding the situation that the screw rod 71 rotates due to accidental touch, etc., so as to ensure that the sleeve 73 and the second detection head 6 are in a stable and accurate position. The first arc groove 17 and the second arc groove 18 are provided to fix the turntable 72 more comprehensively.

[0049] In this embodiment, preferably, please refer to Figure 3-4 , a scale bar 30 is arranged on the detection stand 4, and a pointer 31 is arranged on the sleeve 73 in the direction of the scale bar 30. When the sleeve 73 moves up and down, it also drives the pointer 31 to move. By pointing the pointer 31 to the position of the scale bar 30, the distance moved by the sleeve 73 to drive the second detection head 6 can be clearly and intuitively known, so that the height of the second detection head 6 can be adjusted more accurately, and the use effect is good.

[0050] In this embodiment, preferably, please refer to Figure 4-5 The side wall of the detection vertical plate 4 is provided with two shifting grooves 14, and a sliding block 15 is slidably connected in the shifting groove 14. The outer ends of the two sliding blocks 15 are respectively connected to the upper baffle plate 10 and the lower baffle plate 11. A second elastic member 16 is arranged between the sliding block 15 and the upper and lower inner walls of the shifting groove 14. The second elastic member 16 in the present application is a spring. When the upper baffle plate 10 and the lower baffle plate 11 are moved down and up along the detection vertical plate 4, the upper baffle plate 10 and the lower baffle plate 11 will drive the sliding block 15 to slide along the shifting groove 14, and the shifting groove 14 will stretch or compress the second elastic member 16 in the shifting groove 14. When the upper baffle plate 10 and the lower baffle plate 11 are fixed by the limiting mechanism 9, the upper baffle plate 10 and the lower baffle plate 11 can be restored to the initial position through the second elastic member 16, so as to facilitate the height adjustment of the grab frame 201 at the next position.

[0051] In this embodiment, preferably, please refer to Figure 5 and Figure 7A fixing plate 8 is provided on the sleeve 73, and two insertion holes 13 are provided on the fixing plate 8. The limiting mechanism 9 includes: a limiting column 91, which is provided on the upper baffle plate 10 or the lower baffle plate 11 and is adapted to the insertion hole 13; a limiting block 92, which is movably plugged into the limiting column 91; a first elastic member 93, one end of which is provided inside the limiting column 91, and the other end is connected to the limiting block 92. The first elastic member 93 in the present application is a spring. When the upper baffle plate 10 or the lower baffle plate 11 moves, the limiting column 91 will be driven to move, and the limiting column 91 will gradually enter the insertion hole 13 of the fixing plate 8. At this time, the inner wall of the insertion hole 13 will squeeze the limiting block 92 so that it will gradually enter the limiting column 91 and finally enter completely. When the upper baffle plate 10 or the lower baffle plate 11 moves, it will continue to drive the limiting column 91. When the limiting block 92 is separated from the insertion hole 13, the limiting block 92 will be driven to move outward by the rebound force of the first elastic member 93, such as Figure 4-5 As shown, the limiting block 92 will limit the limiting column 91 on the fixing plate 8, that is, the lower baffle 11 cannot move downward, and the upper baffle 10 cannot move upward. After the adjustment is completed, it is only necessary to press the limiting block 92 to make it completely enter the limiting column 91, and then drive the limiting column 91 to be separated from the insertion hole 13, and the disassembly and assembly are very simple and convenient.

[0052] In this embodiment, preferably, please refer to Figure 1-2 and Figure 4 , further comprising: a slideway 21, arranged on the bottom plate 3; a slide seat 22, slidably arranged on the slideway 21, and the bottom of the detection vertical plate 4 is connected to the slide seat 22. When the detection vertical plate 4 moves, the detection vertical plate 4 will drive the slide seat 22 to slide along the slideway 21, and can drive the detection vertical plate 4 to move to different positions, so that the height of the gripping frame 201 and the gripping beam 203 at various positions on the same spinning frame body 1 can be adjusted, without manual removal and placement, which is more convenient for calibration, saving time and effort, and has strong practicality.

A positioning bolt 25 is connected to the inner thread of the through hole 24. After the positions of the slide seat 22 and the detection stand 4 are adjusted, the positioning bolt 25 is rotated to align it with the positioning hole 23 on the slideway 21, so that the slide seat 22 can be fixed on the slideway 21, so that the subsequent adjustment of the grab frame 201 and the gripping beam 203 is more stable and accurate.

[0054] In this embodiment, preferably, please refer to Figure 8-9The inner walls of both sides of the slide 22 are provided with mounting frames 26, and a plurality of rollers 27 are rotatably provided on the mounting frames 26, and the rollers 27 slide and fit with the outer wall of the slideway 21. When the slide 22 slides along the slideway 21, the rollers 27 slide against the outer wall of the slideway 21, thereby greatly reducing the friction force of the slide 22, and thus making the slide 22 and the detection stand 4 move more smoothly, saving time and effort, and having a good use effect.

[0055] In this embodiment, preferably, please refer to Fig. 9 The side wall of the slide 22 is provided with an inner groove 28, and the mounting frame 26 is slidably inserted in the inner groove 28.

When the slide 22 is placed on the slide 21, the slide 22 can be directly pressed down from the top of the slide 21, and the mounting frame 26 and the roller 27 will be pressed into the inner groove 28 and compress the third elastic member 29. When the slide 22 moves down to the specified position, the rebound force of the third elastic member 29 will drive the mounting frame 26 and the roller 27 to move outward, and finally the roller 27 will fit the outer wall of the slide 21. The installation is simple and convenient, and the slide 22 can be installed from the end of the slide 21, which is highly flexible.
