Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a fancy twisting hollow spindle with a bobbin stripping device among textile machinery components. Background Art

[0002] The spindle is an important component in textile machinery, used to place the yarn bobbin for yarn feeding. The spindle rod on which the yarn bobbin is installed is driven to rotate by the drive belt of the machine. When the yarn bobbin needs to be replaced and new yarn needs to be connected, the spindle rod is disengaged from the drive belt and the bobbin is removed after braking. The spindle rod is generally disengaged by swinging or sideways.

[0003] The bobbin wound with yarn is called a yarn tube. Therefore, each time a new yarn is connected, the bobbin is replaced from the spindle rod and the yarn tube is installed. Due to the high rotation speed of the spindle rod, the rotation and jumping of the yarn tube should be minimized. Therefore, in addition to using alloy materials, the existing bobbin also processes the bobbin and the spindle rod into a taper match with better coaxiality. The taper-matched bobbin and spindle rod are prone to locking. Sometimes the bobbin on the spindle rod is not easy to remove. Therefore, a common situation is that the operator uses a tool or directly uses the disk edge of another bobbin to rigidly knock the lower disk edge of the bobbin on the spindle rod to withdraw the bobbin. Long-term operation in this way will cause deformation of the bobbin and spindle rod, affecting the service life of the entire spindle and the service life of the bobbin. In particular, the number of spindles is large, and some equipment has nearly two hundred spindles. Generally, the yarn needs to be replaced once every 24 hours. This bobbin-removing method will increase the yarn changing time a lot. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fancy twist hollow spindle with a bobbin removing device, wherein the hollow spindle can conveniently remove the bobbin, and the bobbin removing process will not cause any damage to the bobbin and the spindle rod.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a fancy twist hollow spindle with a bobbin stripping device, comprising a spindle rod for mounting a bobbin, the spindle rod being rotatably arranged on a spindle seat, the spindle seat being provided with a handle for switching the spindle seat between working and non-working positions, the upper part of the spindle rod being provided with a conical section matching the conical hole of the bobbin, the fancy twist hollow spindle also having a bobbin stripping device, the bobbin stripping device comprising a bobbin stripping seat, a lower handle cam, an upper cam ring, a bearing ring, an anti-stripping ring and a tube jacking plate, all of which are annular parts and sleeved on the spindle rod;

[0006] The lower end of the bobbin stripping tube seat is detachably fixed on the spindle seat;

[0007] The lower handle cam comprises a lower cam ring located in the bobbin stripping tube seat and a handle extending from the lower cam ring as a whole, and a handle hole for allowing the handle to extend is provided on the ring wall of the bobbin stripping tube seat;

[0008] The upper cam ring is located above the lower cam ring, and has a cam structure on the end surfaces of the lower cam ring and the upper cam ring that are close to each other, so that the axial distance between the lower cam ring and the upper cam ring changes when the lower cam ring and the upper cam ring rotate relative to each other. The upper cam ring is arranged in the form of a circumferential rotation stop in the bobbin seat;

[0009] The lower end surface of the lower cam ring is covered on the upper end surface of the outer ring of the bearing ring, and the inner ring of the bearing ring is covered on the upper end surface of the retaining ring arranged on the spindle rod;

[0010] The anti-slip ring is arranged at the upper opening of the bobbin holder to prevent the upper cam ring from sliding upwards away from the bobbin holder;

[0011] The top pipe disc is arranged on the upper cam ring;

[0012] The twisted hollow spindle drives the upper cam ring to rise when the lower handle cam is turned, and the upper cam ring drives the tube-pushing plate to push the bobbin upward, and the reaction force of pushing the bobbin is applied to the retaining spring through the bearing ring and then acts on the spindle rod.

[0013] Specifically, considering the deviation in the distance between the bobbin and the spindle seat, the starting position of the top tube disk needs to be adjustable, so the inner wall of the upper cam ring has an internal thread, the top tube disk is provided with an external thread, and the top tube disk is screwed onto the upper cam ring in the form of a threaded connection.

[0014] Furthermore, it is best that the starting position of the above-mentioned top pipe disk can be positioned in the circumferential direction after adjustment. Therefore, a circumferential positioning groove is provided at the external thread of the top pipe disk, and a radial through hole is provided on the annular wall at the internal thread of the upper cam ring, with a positioning spring, and the positioning part of the positioning spring is elastically pressed in the positioning groove through the radial through hole.

[0015] Specifically, in order to avoid friction between the retaining spring on the spindle rod and the bearing ring when the spindle rod rotates, the pattern twist hollow spindle also has a reset elastic sleeve for keeping the bearing ring and the retaining spring separated when the spindle rod is in a working state, and the upper end of the reset elastic sleeve is pressed against the bearing ring, and the lower end is directly or indirectly pressed against the spindle bearing seat of the pattern twist hollow spindle.

[0016] Specifically, in order to facilitate one-handed operation, the handle of the bobbin stripping device and the handle of the twisting hollow spindle are spaced apart and extend in the same direction, and the pulling of the lower handle cam moves the handle toward the handle direction.

[0017] Specifically, the cam structure between the lower cam ring and the upper cam ring is a circumferentially evenly distributed oblique wedge-shaped groove on the end surface of the lower cam ring and a circumferentially evenly distributed oblique wedge-shaped boss on the end surface of the upper cam ring, and the oblique wedge-shaped boss and the oblique wedge-shaped groove are meshed with each other.

[0018] Specifically, the structure in which the upper cam ring is arranged in the form of a circumferential stop in the bobbin removal tube seat is that the outer wall of the upper cam ring is circumferentially evenly distributed with first protrusions, the inner wall of the bobbin removal tube seat is circumferentially evenly distributed with first grooves, and the first protrusions and the first grooves are slidably matched.

[0019] Specifically, the structure in which the lower end of the bobbin stripping tube seat is detachably fixed on the spindle seat is that the lower end of the bobbin stripping tube seat is evenly distributed on the circumference with first elastic hooks extending radially outward, the inner wall of the spindle seat is provided with a first hook groove, the first elastic hook is buckled in the first hook groove, the upper mouth of the spindle seat is provided with at least one anti-rotation groove, and the bobbin stripping tube seat is axially extended with an anti-rotation boss embedded in the anti-rotation groove.

[0020] Specifically, the structure of the anti-slip ring arranged on the upper mouth of the bobbin seat is that the upper mouth of the bobbin seat is evenly distributed with second elastic hooks extending radially inward, the second elastic hooks are pressed on the anti-slip ring, and the inner circle of the anti-slip ring is distributed with elastic pressure feet pressing on the upper cam circle, and the elastic pressure feet tend to move the upper cam circle and the top tube disk downward and reset.

[0021] The beneficial effects of the present invention are as follows: the hollow spindle of the present invention is provided with a bobbin stripping device on the spindle seat, and the bobbin can be withdrawn by simply turning the handle, and the reaction force to the bobbin top force still acts on the spindle rod, which has a reliable fulcrum, and the bobbin stripping operation is easier with the help of the handle of the hollow spindle; the bobbin stripping device can also serve as an upper cover of the spindle seat; in particular, this structure can greatly shorten the yarn changing time.
