Description

Technical Field

[0001] The utility model relates to the technical field of polyester yarn production, in particular to a winding device for polyester yarn production. Background Art

[0002] The scientific name of polyester is polyester fiber. It is a synthetic fiber made by chemical polycondensation of organic dibasic acid and diol. It is a kind of polymer compound. Polyester is a synthetic fiber with high strength, high modulus and low water absorption, so it is widely used in civil fabrics and industrial fabrics. Polyester is generally produced by melt spinning, and the produced polyester yarn needs to be rolled into a certain shape.

[0003] In the prior art, a winding machine is usually used to wind up the polyester yarn. The winding machine usually uses an inflatable shaft to fix the bobbin, and uses a motor to drive the inflatable shaft to rotate, thereby driving the bobbin to rotate, and then winding the polyester yarn. The inflatable shaft can increase the speed of bobbin replacement, thereby improving production efficiency. However, as the amount of polyester wound on the bobbin increases, the overall mass of the bobbin increases, and the bobbin and the inflatable shaft are prone to slippage, causing the bobbin to fall off. If the tensioning pressure of the inflatable shaft is increased, the bobbin is easily deformed. Utility Model Content

[0029] Embodiment 1:

[0030] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0031] A winding device for producing polyester yarns, comprising:

[0032] The winding device 1 includes a frame 11, a pneumatic shaft 13 is provided on the front side of the frame 11, a winding sleeve 19 is provided on the outside of the pneumatic shaft 13, the pneumatic shaft 13 is driven by a winding motor 14, a plurality of guide grooves 12 are evenly provided on the frame 11 and below the pneumatic shaft 13, a clamping device 2 is provided on the back side of the frame 11, and the clamping device 2 is connected to a clamping roller 3 through the guide groove 12.

[0033] The frame 11 is made of metal plates welded together. There are three guide grooves 12, and the axes of the three guide grooves 12 intersect with the axis of the inflatable shaft 13.

[0034] The winding motor 14 is fixedly installed on the back of the frame 11 by bolts, and the output shaft of the winding motor 14 passes through the frame 11 and is fixedly connected to the air shaft 13 through a coupling. The winding motor 14 adopts a servo motor, and the winding motor 14 can drive the air shaft 13 to rotate. The winding sleeve 19 is sleeved on the outside of the air shaft 13. After the air shaft 13 is passed through high-pressure air, the shaft diameter increases, and the winding sleeve 19 can be fixed by friction. When the air shaft 13 rotates, it can drive the winding sleeve 19 to rotate.

[0035] A guide wheel 15 and three tension wheels 16 are rotatably installed on the front side of the frame 11. The top tension wheel 16 is fixedly connected to a tension bracket 17 through a rotating shaft. The tension bracket 17 is rotatably installed on the top of the front side of the frame 11. A tension spring 18 is clamped at the lower middle part of the tension bracket 17. The bottom of the tension spring 18 is fixedly connected to the frame 11 by bolts.

[0036] The polyester yarn passes through the tension wheel 16 and the guide wheel 15 in sequence and is fixedly connected to the winding sleeve 19. When the tension of the polyester yarn changes, the uppermost tension wheel 16 can be driven to rotate up and down, thereby stretching or compressing the tension spring 18, and the elastic force of the tension spring 18 is used to compensate for the tension change of the polyester yarn.

[0037] The clamping device 2 includes a guide block 22, the front side of which is connected to the clamping roller 3 through a mounting frame 26, and the guide block 22 is connected to a reset device, which is used to drive the guide block 22 to move toward the inflatable shaft 13. The reset device includes a guide rod 21, which is fixedly mounted on the back of the frame 11 and parallel to the guide groove 12, the guide block 22 is slidably connected to the guide rod 21, and a reset spring 24 is provided on the guide rod 21 and below the guide block 22.

[0038] The guide rod 21 is fixedly mounted on the back of the frame 11 through a bracket, and the guide block 22 can slide along the axis direction of the guide rod 21. When the guide block 22 slides downward due to external force, the return spring 24 is compressed, and the elastic force of the return spring 24 makes the guide block 22 tend to move upward. When the external force on the guide block 22 disappears, the guide block 22 slides upward under the elastic force of the return spring 24.

[0039] The head of the guide block 22 is inserted into the guide groove 12, and clamping plates 23 are welded on both sides of the guide block 22. Distance meters 25 are provided below the clamping plates 23 and on both sides of the bottom end of the guide rod 21. The distance meters 25 are used to measure the distance from the bottom end of the clamping plates 23 to the end face of the distance meters 25.

[0040] Because the head of the guide block 22 is inserted into the guide groove 12 , the guide groove 12 can limit the sliding direction of the guide block 22 and prevent the guide block 22 from rotating.

[0041] The distance meter 25 adopts a known infrared or laser distance meter. The distance meter 25 can measure the distance from the bottom end of the clamping plate 23 to the end face of the distance meter 25, so as to obtain the moving distance of the guide block 22.

[0042] The mounting frame 26 is located at the front of the frame 11 . The mounting frame 26 is fixedly connected to the guide block 22 . The mounting frame 26 cooperates with the clamping plate 23 to clamp the frame 11 .

[0043] The mounting frame 26 is fixedly connected to the guide block 22 by bolts. When the guide block 22 slides, it can drive the mounting frame 26 to move together. When the mounting frame 26 is subjected to a downward force, it can drive the guide block 22 to move downward.

[0044] The clamping roller 3 includes an anti-slip roller 31, which abuts against the surface of the winding sleeve 19. Both ends of the anti-slip roller 31 are rotatably connected to a rotating frame 32. The bottom of the rotating frame 32 is connected to the mounting frame 26 through an adjusting device, and the adjusting device is used to adjust the spacing of the rotating frame 32.

[0045] Both ends of the anti-slip roller 31 are inserted into the rotating frame 32 and are rotatably connected to the rotating frame 32 via bearings.

[0046] Both ends of the anti-slip roller 31 are truncated cones, and the diameter of the end surface of the anti-slip roller 31 is smaller than the diameter of the middle portion.

[0047] Both ends of the anti-slip roller 31 are truncated cones, which can facilitate the insertion of the winding sleeve 19.

[0048] The adjusting device comprises a guide frame 33 , the tail of the guide frame 33 is fixedly connected to the mounting frame 26 , the inside of the guide frame 33 is hollow, and an opening is provided at the top of the guide frame 33 .

[0049] The guide frame 33 is made of metal, and the guide frame 33 is fixedly connected to the mounting frame 26 by bolts. The rotating frame 32 near one side of the frame 11 is welded and installed on the top surface of the guide frame 33 near one side of the frame 11.

[0050] A guide shaft 35 is mounted in the guide frame 33 , and an adjustment spring 34 is sleeved on the guide shaft 35 . A guide slider 36 is provided on the guide shaft 35 and located on the side of the adjustment spring 34 close to the frame 11 . The guide slider 36 is fixedly connected to the outer rotating frame 32 through a connecting plate 37 .

[0051] The outer side surface of the guide slider 36 abuts against the end surface of the adjustment spring 34. The top of the guide slider 36 passes through the top opening of the guide frame 33 and is fixedly connected to the connecting plate 37 by screws. The head of the connecting plate 37 is welded to the outer rotating frame 32. Applying an outward pulling force to the outer rotating frame 32 can drive the outer rotating frame 32 to move outward, thereby driving the guide slider 36 to slide outward along the guide shaft 35 through the connecting plate 37, thereby compressing the adjustment spring 34. Insert the two ends of the anti-slip roller 31 into the rotating frame 32, remove the external force applied to the rotating frame 32, and at this time, the adjustment spring 34 drives the guide slider 36 to move in the direction of the frame 11, thereby driving the rotating frame 32 to move inward through the connecting plate 37 to achieve the clamping of the anti-slip roller 31.

[0052] When using the device in this embodiment, the operator selects a winding sleeve 19 of different lengths according to production needs, and selects an anti-slip roller 31 of different lengths according to the length of the winding sleeve 19 .

[0053] The outer rotating frame 32 exerts an outward pulling force to drive the outer rotating frame 32 to move outward, thereby driving the guide slider 36 to slide outward along the guide shaft 35 through the connecting plate 37, thereby compressing the adjustment spring 34. Insert both ends of the anti-slip roller 31 of appropriate length into the rotating frame 32, remove the external force applied to the rotating frame 32, and at this time, the elastic force of the adjustment spring 34 drives the guide slider 36 to move toward the direction of the frame 11, thereby driving the rotating frame 32 to move inward through the connecting plate 37, thereby fixing the anti-slip roller 31.

[0054] Insert a winding sleeve 19 of appropriate length into the outside of the inflatable shaft 13 from the inclined surface in front of the anti-slip roller 31, pass compressed air into the inflatable shaft 13 to change the outer diameter of the inflatable shaft 13, and fix the winding sleeve 19.

[0055] The polyester yarn passes through the tension wheel 16 and the guide wheel 15 in sequence and is fixedly connected to the winding sleeve 19.

[0056] At this time, the surface of the anti-slip roller 31 contacts the surface of the winding sleeve 19. The distance from the clamping plate 23 to the end face of the distance meter 25 is measured by the distance meter 25, which is recorded as the initial value.

[0057] The winding motor 14 is started to drive the air shaft 13 to rotate, thereby driving the winding sleeve 19 to rotate, and then winding the polyester yarn.

[0058] As the polyester yarn is wound, the diameter of the coil increases, and the polyester yarn presses the anti-slip roller 31 outward. The external force on the anti-slip roller 31 is transmitted to the guide frame 33 through the rotating frame 32. The guide frame 33 transmits the external force to the mounting frame 26, thereby driving the guide block 22 to move downward and compressing the return spring 24. The elastic force of the return spring 24 is used to keep the anti-slip roller 31 in contact with the polyester yarn at all times, exert an upward force on the polyester yarn, and support the polyester yarn and the winding sleeve 19.

[0059] The distance from the clamping plate 23 to the end face of the distance meter 25 is measured in real time by the distance meter 25 , and the difference between the measured value and the initial value is recorded as the wire coil thickness.

[0060] When the thickness of the coil reaches the required value, the winding motor 14 is stopped, the polyester yarn is cut, the winding sleeve 19 and the coil are removed, and a new winding sleeve 19 is replaced. The winding is continued.

[0061] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
