Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber equipment production, in particular to a centrifugal cylinder spindle shaft unloading device for a chemical fiber spinning component. Background Art

[0002] In the prior art, a spinning component of an energy-saving electric spindle, namely a spinning electric spindle, is widely used in semi-continuous spinning machines of chemical fiber production equipment. During production, the spinning electric spindle rotates at high speed to twist, barrel, and dehydrate the spun yarn, thereby completing the spinning process. The spinning electric spindle consists of a centrifugal cylinder and a spindle shaft, and is the main component of chemical fiber spinning. During the production process, when the spinning machine is continuously running, the spinning electric spindle needs to be replaced when phenomena such as burning of the yarn package, flying cylinder, peeling of the bottom of the centrifugal cylinder body, and shaking of the centrifugal cylinder head occur, so as to ensure the smooth progress of the yarn twisting, barreling, and dehydration. Replacing the centrifugal cylinder requires pulling out the spindle shaft and separating the centrifugal cylinder from the spindle shaft. Currently, the known method for pulling out the spindle shaft is to use the screw hole M5 at the end of the shaft as the fulcrum, but the pulling force is insufficient, which can easily cause the M5 screw to break. Another method is to bend the spindle shaft and then use a hook to pull it diagonally, but this can easily cause defects such as the bottom hole of the centrifugal cylinder to break, the spindle shaft to break, and the spindle shaft root to be unable to be pulled out. The two existing methods both cause damage to the spindle shaft and the centrifugal cylinder, resulting in low efficiency, large waste, and high production costs. They also bring difficulties to component configuration and reduced product quality to chemical fiber production enterprises, directly affecting the normal operation of production. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of the invention of the utility model is to provide a centrifugal cylinder spindle shaft disassembly device for a chemical fiber spinning component, so as to achieve safe separation of the centrifugal cylinder body and the spindle shaft, high working efficiency, no damage to components, and achieve the purpose of saving production costs.

[0004] To achieve the above-mentioned purpose of the invention, the utility model provides a spindle shaft unloading device for a chemical fiber spinning component centrifugal cylinder, comprising a main frame, a clamping member, a lifting device, and a jack; a clamping member is provided on the top of the vertical plate of the main frame, and a lifting device is provided on the upper part of the vertical plate of the main frame; two fixed slides of the lifting device are fixedly connected to the vertical plate, and movable slides are respectively slidably provided in the inner holes of the two fixed slides, the lower ends of the two movable slides are connected to the lower disc, and the upper ends of the movable slides are connected to the upper disc, and the upper disc is provided with a central circular hole, and the spindle shaft of the centrifugal cylinder passes through the central circular hole of the upper disc and is connected to the clamping member; the outer diameter of the outer circle of the centrifugal cylinder is larger than the diameter of the central circular hole of the upper disc, and the cylinder body of the centrifugal cylinder is tightly connected to the spindle shaft;

[0005] A jack is provided on the bottom plate of the main frame, and the top plate of the jack contacts the bottom surface of the lower disc of the lifting device;

[0006] The jack pushes the movable slide rail of the lower disc to move upward along the fixed slide seat, and the upper disc stuck at the bottom end of the centrifugal cylinder presses the centrifugal cylinder upward, so that the centrifugal cylinder is separated from the spindle shaft on the clamping component.

[0007] Furthermore, the main frame is also provided with side panels, the bottom ends of the side panels are fixedly connected to the bottom panel, and the side edges of the side panels are fixedly connected to the vertical panels.

[0008] Furthermore, the clamping member includes a clamping seat and a pressure cover. One side of the clamping seat is connected to the vertical plate bolt, and the other side is provided with a semicircular arc groove. The pressure cover, which also has a semicircular arc groove on the inner side, is connected to the clamping seat via a fixing bolt; the semicircular arc grooves of the clamping seat and the pressure cover are combined into a circular hole, and the spindle shaft of the centrifugal cylinder passes through the circular hole formed by the clamping seat and the pressure cover, and the spindle shaft is clamped by the fixing bolt through the pressure cover and the clamping seat.

[0009] Furthermore, the height of the movable slide rail is greater than the length of the spindle shaft.

[0010] Furthermore, the head end of the spindle shaft is processed with a flat surface, which is tightly connected to the copper sleeve in the bottom hole of the centrifugal cylinder body. The end of the spindle shaft is deeply inserted into the copper sleeve of the centrifugal cylinder, and the copper sleeve is embedded in the bottom of the centrifugal cylinder body.

[0011] Furthermore, the centrifugal cylinder, spindle shaft, clamping member and jack are concentrically arranged.

[0012] During use, the centrifugal cylinder with the spindle shaft is placed into the inner hole of the upper disc, and the spindle shaft passing through the inner hole of the upper disc enters the circular hole formed by the clamping seat and the pressure cover. The fixing bolts fix the spindle shaft to the clamping seat connected to the main frame vertical plate. When the jack is started, the top plate of the jack pushes the bottom surface of the lower disc upward, and the lower disc pushes the movable slide rail to move upward along the fixed slide seat, and drives the upper disc stuck at the bottom end of the centrifugal cylinder to press the centrifugal cylinder upward. The friction force between the copper sleeve in the centrifugal cylinder body and the spindle shaft is less than the clamping force between the clamping seat and the spindle shaft. The upper disc pushes the centrifugal cylinder body upward to separate from the spindle shaft, thereby achieving the purpose of removing the centrifugal cylinder from the spindle shaft.

[0013] Compared with existing technologies, the present invention provides a vertical centrifugal cylinder spindle shaft removal device. Using a jack, a clamping member, and a lifting device, the centrifugal cylinder and spindle shaft can be separated and removed, ensuring that the inner bore of the centrifugal cylinder and the end of the spindle shaft remain intact and free of wear, without affecting the continued use of the components after repair. This device solves the problem of centrifugal cylinders being unable to be removed or repaired. This device offers a simple structure, saves time and effort, is stable and reliable, and can effectively save production costs and reduce environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS

The upper disc 3.1 is provided with a central circular hole, and the spindle shaft 5 of the centrifugal cylinder 4 passes through the central circular hole of the upper disc 3.1 and is connected to the clamping member 2; the outer diameter of the cylinder body of the centrifugal cylinder 4 is larger than the diameter of the central circular hole of the upper disc 3.1, and the cylinder body of the centrifugal cylinder 4 is tightly connected to the spindle shaft 5; a jack 6 is provided on the bottom plate 1.1 of the main frame 1, and the top disc of the jack 6 is in contact with the bottom surface of the lower disc 3.4 of the lifting device 3; the jack 6 is a hydraulic jack, and its pressure is sufficient to overcome the clamping force between the centrifugal cylinder 4 and the spindle shaft 5.

[0025] The jack 6 pushes the moving slide rail 3.3 of the lower disc 3.4 to move upward along the fixed sliding seat 3.2, and the upper disc 3.1 stuck at the bottom end of the centrifugal cylinder 4 squeezes the centrifugal cylinder 4 upward, and the spindle shaft 5 on the centrifugal cylinder 4 is separated from the clamping member 2.

[0026] Preferably, the main frame 1 is further provided with a side plate 1.3, the bottom end of the side plate 1.3 is fixedly connected to the bottom plate 1.1, and the side of the side plate 1.3 is fixedly connected to the vertical plate 1.2.

[0027] Preferably, the clamping member 2 includes a clamping seat 2.1 and a gland 2.2. One side of the clamping seat 2.1 is bolted to the vertical plate 1.2, and a semi-circular arc groove is opened on the other side. The gland 2.2 with a semi-circular arc groove on the inner side is connected to the clamping seat 2.1 through a fixing bolt 2.3; the semi-circular arc grooves of the clamping seat 2.1 and the gland 2.2 are combined into a circular hole, and the spindle shaft 5 of the centrifugal cylinder 4 passes through the circular hole formed by the clamping seat 2.1 and the gland 2.2, and the fixing bolt 2.3 presses the spindle shaft 5 tightly through the gland 2.2 and the clamping seat 2.1.
