Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to a winding machine that prevents the yarn cake from flying off. Background Technology

[0002] In the field of textile machinery, winding machines play a crucial role in winding yarn into a coil. Conventional winding speeds can reach over 3000 meters per minute, while high-speed winding heads can even reach around 6000 meters per minute. During the winding process, the coil is primarily secured by a tensioning device to prevent it from slipping off.

[0003] In actual production, equipment maintenance may not be carried out in a timely and effective manner, leading to problems such as wear and tear on the tensioning blocks after long-term use, insufficient dynamic balance accuracy of the equipment, and malfunctions of the tensioning device itself, which cannot be detected and resolved in a timely manner. These hidden dangers can easily cause partial or even complete failure of the tensioning device, thus failing to effectively fix the rotating yarn cake. When the yarn cake loses effective restraint while rotating at high speed, it may slip and fly off the winding machine spindle. Due to the extremely high rotation speed, the kinetic energy of the flying yarn cake is very large, which can not only cause serious damage to the equipment but also pose a great personal safety hazard to production line personnel.

[0004] Therefore, it is necessary to improve existing technologies in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide a winding machine that prevents the yarn cake from flying off.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A winding machine for preventing the yarn cake from flying off includes a winding machine spindle and a motor. One end of the winding machine spindle is connected to the output shaft of the motor, and the machine also includes a disc fixed to the other end of the winding machine spindle.

[0008] The disc body is coaxial with the winding machine spindle shaft, and the diameter of the disc body is less than or equal to the diameter of the winding machine spindle shaft;

[0009] The outer circumferential surface of the disk has n mounting holes, where n is a positive integer;

[0010] Each of the n assembly holes is equipped with one suppression device;

[0011] The suppression device includes a centrifugal component, a limiting component, and a resetting component; the centrifugal component is inserted into the mounting hole in a manner that allows it to move radially within the disc body; the limiting component is used to prevent the centrifugal component from falling out of the mounting hole; the resetting component is used to drive the centrifugal component to reset when it moves radially outward within the disc body.

[0012] When the speed of the winding machine spindle is less than or equal to 200 r / min, the centrifugal component is completely located inside the mounting hole, ensuring that the normal winding of the yarn cake and the unwinding operation are not hindered at low speeds. When the speed of the winding machine spindle is greater than 200 r / min, the centrifugal component protrudes from the mounting hole, and the length of the protruding part is greater than the thickness of the paper tube on the winding machine spindle, which can ensure that the centrifugal component effectively blocks the paper tube and prevents the paper tube from flying off the winding machine spindle.

[0013] As a preferred technical solution:

[0014] As described above, in a winding machine designed to prevent the yarn cake from flying off, n mounting holes are evenly distributed around the central axis of the disc.

[0015] As described above, in a winding machine for preventing the yarn cake from flying off, the centrifugal component is a T-shaped part, consisting of a coaxial round rod and a circular base.

[0016] As described above, in a winding machine designed to prevent the yarn cake from flying off, the limiting component is a set screw;

[0017] The inner wall of the assembly hole is divided into two sections along its axis: the inner section is closer to the central axis of the disc than the outer section. The inner section is a smooth section, while the outer section is a threaded section that is adapted to the set screw. The length of the threaded section is equal to the length of the set screw.

[0018] The set screw is located inside the threaded section and connected to its thread. The set screw has a stepped through hole along its axial direction from the center. The smaller diameter section of the stepped through hole is closer to the circumference of the disc body than the larger diameter section.

[0019] The diameter of the large-diameter section of the stepped through hole is greater than or equal to the diameter of the circular base. The circular base is located inside the smooth section, and the round rod is inserted into the small-diameter section with a clearance fit between the two.

[0020] As described above, in a winding machine for preventing the yarn cake from flying off, the reset component is a spring; the reset component is sleeved on a round rod and clamped between the round base and the step of the stepped through hole.

[0021] As described above, a winding machine for preventing the yarn cake from flying off has four mounting holes on the outer circumferential surface of the disc.

[0022] As described above, in a winding machine designed to prevent the yarn cake from flying off, the diameter of the disc is 0.1-3mm smaller than the diameter of the winding machine spindle, ensuring the smooth exit of the yarn cake.

[0023] As described above, in a winding machine designed to prevent the yarn cake from flying off, the thickness of the disc body is 6-10 mm larger than the diameter of the set screw.

[0024] As described above, in a winding machine designed to prevent the yarn cake from flying off, the set screw is an internal hexagonal set screw, which is convenient to use with assembly tools to enable the installation and removal of the set screw.

[0025] As described above, in a winding machine designed to prevent the yarn cake from flying off, the diameter of the round rod is 0.2-0.5 mm smaller than the diameter of the smaller diameter section to facilitate the sliding of the centrifugal components.

[0026] Beneficial effects:

[0027] This invention solves the safety hazard of the silk cake flying off during high-speed rotation by setting a disc with a centrifugal component, a limiting component and a resetting component at the other end of the winding machine spindle shaft. The centrifugal component expands and contracts when the rotation speed changes. Attached Figure Description

[0031] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0032] A winding machine to prevent the yarn cake from flying off, such as Figure 1 , Figure 2 As shown, it includes a winding machine spindle 10, a motor 9, and a disc body 1;

[0033] like Figure 2 As shown, one end of the winding machine spindle 10 is connected to the output shaft of the motor 9, and the disc 1 is fixed to the other end of the winding machine spindle 10; the disc 1 is coaxial with the winding machine spindle 10, and the diameter of the disc 1 is 0.1-3mm smaller than the diameter of the winding machine spindle 10.

[0034] like Figure 1As shown, four mounting holes 6 are provided on the outer circumferential surface of the disc body 1. The four mounting holes 6 are evenly distributed around the central axis of the disc body 1. The inner wall of the mounting hole 6 is divided into inner and outer sections along its axial direction. The inner section is closer to the central axis of the disc body 1 than the outer section. The inner section is a smooth section and the outer section is a threaded section.

[0035] Each of the four assembly holes 6 is equipped with a suppression device;

[0036] like Figure 1 As shown, the suppression device includes a centrifugal component 4, a set screw 2, and a reset component 5;

[0037] Centrifugal component 4 is a T-shaped part, consisting of a coaxial round rod and a circular base;

[0038] Set screw 2 is an internal hexagon set screw, located in the threaded section of the inner wall of the mounting hole 6 and connected to it by threads. The length of set screw 2 is equal to the length of the threaded section, and the diameter of set screw 2 is 6-10mm smaller than the thickness of disc body 1.

[0039] The set screw 2 has a stepped through hole along its axial direction from the center. The smaller diameter section of the stepped through hole is closer to the circumference of the disc 1 than the larger diameter section. The diameter of the larger diameter section is greater than or equal to the diameter of the circular base. The circular base is located in the smooth section. The round rod passes through the smaller diameter section with a clearance fit between the two. The diameter of the round rod is 0.2-0.5 mm smaller than the diameter of the smaller diameter section. The set screw 2 is used to prevent the centrifugal component 4 from falling out of the assembly hole 6.

[0040] The reset component 5 is a spring; the reset component 5 is sleeved on the round rod and clamped between the round base and the step of the stepped through hole. The reset component 5 is used to drive the centrifugal component 4 to reset when the centrifugal component 4 moves radially outward along the disc body 1.

[0041] The motor 9 of the winding machine drives the winding machine spindle 10 to rotate. When the rotation speed of the winding machine spindle 10 is less than or equal to 200 r / min, the centrifugal component 4 is completely located in the assembly hole 6 and does not contact the paper tube on the winding machine spindle 10, ensuring that the normal winding and unwinding operation of the yarn cake 8 is not hindered at low speed. When the rotation speed of the winding machine spindle 10 is greater than 200 r / min, the centrifugal component 4 moves outward along the radial direction of the disc 1 due to centrifugal force and protrudes from the assembly hole 6. The length of the protruding part is greater than the thickness of the paper tube on the winding machine spindle 10, preventing the yarn cake 8 from flying off the winding machine spindle 10 when rotating at high speed.
