Description

Technical Field

[0001] The present invention relates to the technical field of cloth winding, and particularly relates to a winding structure for polyester cloth and its winding process. Background Art

[0002] Polyester cloth is a synthetic fabric made of polyester fibers, also known as polyester fiber or PET fiber. After the existing polyester cloth production device produces polyester cloth, it is also necessary to wind the polyester cloth onto a winding roller through a winding structure, so as to facilitate the subsequent transportation and processing of the polyester cloth.

[0003] It is found through prior art retrieval that the Chinese patent with the publication number CN219859695U discloses a winding machine with a quick replacement function. When the rotating rod shell moves to a suitable position, the cloth winding cylinder disengages from the rotating rod shell. At this time, the wound cloth winding cylinder can be removed from the rotating rod, and then a new cloth winding cylinder is sleeved on the surface of the rotating rod. The output end of the motor drives the threaded block to rotate along the surface of the threaded groove until the plugging block completely moves into the inner cavity of the plugging groove, and the cloth winding cylinder is replaced. At this time, the machine body can be started for winding operation.

[0004] However, it is worth considering that during the process of disassembling and assembling the cloth winding cylinder, the machine body has been in a stopped state, resulting in a reduction in effective production time, especially having a more significant impact on high-speed production lines, and there are certain limitations.

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0039] Embodiment 1, given by Figure 1 and Figure 2 The present invention includes a frame 1 and two lifting seats 2. A plurality of first hydraulic telescopic rods 21 are fixedly installed at the top of the frame 1. The telescopic ends of the first hydraulic telescopic rods 21 are fixedly connected to the corresponding lifting seats 2. Two translation seats 3 are slidably connected to the sides of the two lifting seats 2 away from each other;

[0040] Rotating shafts 4 are rotatably connected to the ends of adjacent two translation seats 3 away from each other. A cloth winding cylinder 6 is provided between the corresponding two rotating shafts 4. The rotating shafts 4 are equipped with a positioning mechanism for positioning the position of the cloth winding cylinder 6. The frame 1 is equipped with a driving assembly for driving the rotation of the rotating shafts 4, and the frame 1 is equipped with a cutting and installation structure for fixing the polyester cloth on the cloth winding cylinder 6;

[0041] The cloth reel 6 at the winding station is driven to rotate by the driving component, and the polyester cloth is wound by the cloth reel 6, and the double-sided tape is attached to the surface of the cloth reel 6 at the first loading and unloading station by an external manipulator or manually. When it is necessary to remove the cloth reel 6 at the winding station, the polyester cloth is cut by the cutting installation structure, and the lifting seat 2 and the translation seat 3 are driven downward by the first hydraulic telescopic rod 21 to move the cloth reel 6 at the winding station to the second loading and unloading station, and the cloth reel 6 at the first loading and unloading station moves to the winding station, and the end of the polyester cloth after cutting is driven by the cutting installation structure to move onto the double-sided tape, so that the end of the polyester cloth is fixedly connected to the cloth reel 6 at the winding station, and the cloth reel 6 at the winding station is driven to rotate by the driving component, and the polyester cloth is wound by the cloth reel 6. At this time, the positioning and fixation of the cloth reel 6 at the second loading and unloading station is released by the positioning mechanism, and the positioning is released by taking away the released cloth reel by the external manipulator. The cloth winding drum 6 at the winding station is used to cut the polyester cloth, and the cloth winding drum 6 without polyester cloth is installed, and double-sided tape is pasted on the cloth winding drum 6. When it is necessary to replace the cloth winding drum 6 at the winding station again, the polyester cloth is cut by the cutting installation structure, and the lifting seat 2 and the translation seat 3 are driven to move to the initial position by the first hydraulic telescopic rod 21, so that the cloth winding drum 6 at the winding station can be moved to the first loading and unloading station. Similarly, the cutting installation structure is used to drive the cut end of the polyester cloth to move onto the double-sided tape, and the cloth winding drum 6 at the first loading and unloading station can be replaced, and the position of the cloth winding drum 6 can be switched. Through the design of double loading and unloading stations, there is no need to replace the cloth winding drum 6 at the winding station, so that the cloth winding drum 6 at the first loading and unloading station or the second loading and unloading station can be wound during the disassembly and assembly process, thereby increasing the effective production time and reducing the downtime waiting time for changing rolls, which is particularly suitable for high-speed production lines of polyester cloth.

[0042] Embodiment 2, based on embodiment 1, Figure 1 , Figure 3 and Figure 7 It is given that the driving assembly includes a first damping disk 5 fixedly mounted on the end of the rotating shaft 4 away from the cloth winding drum 6, and the two sides of the frame 1 are rotatably connected with support shafts 45 respectively, and the support shaft 45 is fixedly mounted with a first slider 7, and a slide groove 8 adapted to the first slider 7 is provided on the side of the first damping disk 5 away from the rotating shaft 4, and guide bars 10 adapted to the slide groove 8 are provided above and below the first slider 7, and the guide bar 10 is fixedly connected to the frame 1, and the frame 1 is installed with a driver for driving the support shaft 45 to rotate, and the driver includes a servo motor 60 fixedly mounted on the frame 1, and a first sprocket 59 is fixedly connected to one of the support shafts 45, and a second sprocket 61 is fixedly connected to the output end of the servo motor 60, and the second sprocket 61 and the first sprocket 59 are connected by a chain 62.

[0043] When the first hydraulic telescopic rod 21 drives the lifting seat 2 to move in the vertical direction, the lifting seat 2 drives the rotating shaft 4 and the first damping disc 5 to move in the vertical direction through the translation seat 3. The sliding groove 8 slides relative to the guiding strip 10. When the first damping disc 5 moves to the winding station, the first damping disc 5 slides to one side of the first slider 7, and the first slider 7 is located in the sliding groove 8. The servo motor 60 is driven to rotate the second sprocket 61, and the second sprocket 61 drives the first sprocket 59 and the support shaft 45 to rotate through the chain 62. The support shaft 45 can drive the first damping disc 5 and the rotating shaft 4 to rotate through the first slider 7, so that the cloth winding cylinder 6 located at the winding station rotates.

[0044] Embodiment 3, on the basis of Embodiment 1, by Figure 11 、 Figure 12 、 Figure 13 and Figure 14Given that the cutting and installation structure includes two first support frames 12 fixedly installed on the frame 1. A guiding roller 13 for guiding the polyester cloth is rotatably connected between the two first support frames 12. Below the guiding roller 13, there are two adjustment seats 14. A positioning roller 15 is rotatably connected between the two adjustment seats 14. On one side of the two adjustment seats 14 close to each other, there are rotating seats 16. A support roller 17 and a first pressing roller 18 are rotatably connected between the two rotating seats 16. The adjustment seat 14 is equipped with a self-rotation unit for driving the rotating seat 16 to rotate. The first support frame 12 is equipped with an adjustment member for changing the position of the adjustment seat 14. Above the positioning roller 15, there is a second pressing roller 28. A lifting frame 29 is rotatably connected to the second pressing roller 28. Above the lifting frame 29, there is an installation strip 30. The two ends of the installation strip 30 are respectively fixedly connected to the two first support frames 12. A number of third hydraulic expansion rods 31 are fixedly connected to the installation strip 30. The telescopic end of the third hydraulic expansion rod 31 is fixedly connected to the top of the lifting frame 29. A cutting mechanism for cutting the polyester cloth is installed on the lifting frame 29. The self-rotation unit includes a connecting shaft 19 rotatably installed on the adjustment seat 14. The connecting shaft 19 is fixedly connected to the rotating seat 16. One end of the connecting shaft 19 away from the rotating seat 16 is fixedly connected with a gear 20. The adjustment seat 14 is fixedly installed with a sixth hydraulic expansion rod 44. The telescopic end of the sixth hydraulic expansion rod 44 is fixedly connected with a toothed plate 22 meshing with the gear 20. The adjustment member includes a second hydraulic expansion rod 23 fixedly installed on the first support frame 12. The bottom of the adjustment seat 14 is fixedly connected with a guiding plate 24. An outer guiding sleeve 25 is slidably sleeved on the outside of the guiding plate 24. And the output end of the second hydraulic expansion rod 23 is fixedly connected to the guiding sleeve 25. One side of the adjustment seat 14 away from the positioning roller 15 is fixedly connected with a guiding column 27. A guiding groove 26 for guiding the guiding column 27 is opened on the first support frame 12. And the guiding column 27 is located in the corresponding guiding groove 26. The cutting mechanism includes a cutting knife 33 arranged above the support roller 17. A number of fourth hydraulic expansion rods 32 are fixedly connected to the lifting frame 29. And the telescopic end of the fourth hydraulic expansion rod 32 is fixedly connected to the cutting knife 33;

[0045] The polyester cloth passes through above the guiding roller 13, and the guiding roller 13 guides the polyester cloth. The polyester cloth then passes between the positioning roller 15 and the second pressing roller 28. When the polyester cloth needs to be cut, the third hydraulic telescopic rod 31 drives the lifting frame 29 and the second pressing roller 28 to move downward, so that the second pressing roller 28 presses the polyester cloth to move towards the positioning roller 15. Finally, the second pressing roller 28 and the positioning roller 15 clamp the polyester cloth. The fourth hydraulic telescopic rod 32 drives the cutting knife 33 to move downward, and the cutting knife 33 cuts off the polyester cloth. The supporting roller 17 supports the cut end of the polyester cloth. The end of the polyester cloth is located between the supporting roller 17 and the first pressing roller 18. The fourth hydraulic telescopic rod 32 drives the cutting knife 33 to move upward, so that the cutting knife 33 resets to the initial position relative to the lifting frame 29. The sixth hydraulic telescopic rod 44 drives the toothed plate 22 to move. The toothed plate 22 drives the connecting shaft 19 and the rotating seat 16 to rotate 180 degrees through the gear 20. The end of the polyester cloth slides from the supporting roller 17 to the side of the positioning roller 15 facing the first pressing roller 18, and the positions of the first pressing roller 18 and the supporting roller 17 are swapped. The end of the polyester cloth is clamped between the positioning roller 15 and the first pressing roller 18. The third hydraulic telescopic rod 31 drives the lifting frame 29 and the second pressing roller 28 to move upward to the initial height, and the second pressing roller 28 no longer presses the polyester cloth. The positioning roller 15 and the first pressing roller 18 complete the fixation of the end of the polyester cloth. When the next cloth winding cylinder 6 without wound polyester cloth moves to the winding station, the second hydraulic telescopic rod 23 drives the guiding sleeve 25 and the guiding plate 24 to translate. The guiding plate 24 drives the adjusting seat 14 and the guiding column 27 to move. The guiding column 27 slides in the guiding groove 26. The adjusting seat 14 drives the positioning roller 15 and the first pressing roller 18 to pass through below the cloth winding cylinder 6. The guiding groove 26 guides the guiding column 27. As the guiding sleeve 25 continues to move, the guiding column 27, the adjusting seat 14 and the guiding plate 24 slide upward relative to the guiding sleeve 25. The polyester cloth on the positioning roller 15 abuts against the double-sided tape. At this time, the sixth hydraulic telescopic rod 44 drives the toothed plate 22 to rotate reversely, so that the first pressing roller 18 no longer presses the polyester cloth. After releasing the fixation of the first pressing roller 18 on the polyester cloth, the second hydraulic telescopic rod 23 drives the guiding sleeve 25 to continue to move, and the positioning roller 15 rolls relative to the double-sided tape and the cloth winding cylinder 6, so that the positioning roller 15 presses the end of the polyester cloth on the double-sided tape. Finally, the end of the polyester cloth is fixed relative to the cloth winding cylinder 6. By driving the guiding sleeve 25 to move reversely through the second hydraulic telescopic rod 23, the adjusting seat 14 and the positioning roller 15 can be reset to the initial position, completing the cutting and fixation of the polyester cloth. There is no need for manual fixation of the polyester cloth on the cloth winding cylinder 6, further improving the production efficiency.

[0046] Embodiment 4, based on Embodiment 2, consists of Figure 2 、 Figure 3 、 Figure 5 、 Figure 10 and Figure 11As shown, the positioning mechanism includes a mounting seat 34 fixedly installed at one end of the rotating shaft 4 away from the first damping disc 5. A receiving groove 35 for receiving the end of the fabric roll 6 is formed on the side of the mounting seat 34 away from the rotating shaft 4. A support column 36 for inserting into the fabric roll 6 is fixedly connected in the receiving groove 35. Clamping plates 37 are symmetrically arranged on both sides of the support column 36. A sliding plate 38 is fixedly connected to the side of the clamping plate 37 away from the support column 36. A first support portion 39 located outside the receiving groove 35 is fixedly connected to one end of the sliding plate 38 away from the clamping plate 37. The first support portion 39 and the mounting seat 34 are connected by a first compression spring 40. Two second support frames 41 are fixedly connected to the frame 1. Arc-shaped plates 42 matching the ends of the sliding plates 38 are arranged on the sides of the second support frames 41 and the first support frame 12 close to each other. A number of fifth hydraulic expansion and contraction rods 43 are fixedly connected to both the first support frame 12 and the second support frame 41, and the expansion and contraction ends of the fifth hydraulic expansion and contraction rods 43 are fixedly connected to the corresponding arc-shaped plates 42. The frame 1 is equipped with a pulling member adapted to the first damping disc 5. The pulling member includes a second slider 9 arranged at one end of the guiding strip 10 away from the first slider 7, and the second slider 9 is adapted to the sliding groove 8. Two fixing frames 56 are fixedly connected to both sides of the frame 1. A movable frame 58 penetrates through the fixing frames 56. Two seventh hydraulic expansion and contraction rods 57 are fixedly connected to the fixing frames 56, and the expansion and contraction ends of the seventh hydraulic expansion and contraction rods 57 are fixedly connected to the movable frame 58. The movable frame 58 is fixedly connected to the second slider 9;

[0047] When the cloth winding cylinder 6 is at the winding station, the two support columns 36 are respectively located inside the two ends of the cloth winding cylinder 6, and the cloth winding cylinder 6 is supported by the support columns 36. The arc-shaped plate 42 is driven to move by the fifth hydraulic telescopic rod 43, so that two adjacent arc-shaped plates 42 are combined into a ring, and the arc-shaped plate 42 pushes the sliding plate 38 and the clamping plate 37 to move towards the cloth winding cylinder 6. The first compression spring 40 is in a compressed state, and two adjacent clamping plates 37 clamp the cloth winding cylinder 6, so that the cloth winding cylinder 6 is fixed relative to the mounting seat 34, avoiding the cloth winding cylinder 6 rotating relative to the mounting seat 34 and the rotating shaft 4. When the cloth winding cylinder 6 at the winding station rotates, the mounting seat 34 drives the end of the sliding plate 38 away from the clamping plate 37 to slide on the inner wall of the arc-shaped plate 42. When it is necessary to drive the cloth winding cylinder 6 at the winding station to move to the first loading and unloading station or the second loading and unloading station, the fifth hydraulic telescopic rod 43 drives the arc-shaped plate 42 to move in the reverse direction, so that the arc-shaped plate 42 no longer interferes with the vertical movement of the mounting seat 34, and the arc-shaped plate 42 no longer presses the sliding plate 38. The first compression spring 40 drives the sliding plate 38 and the clamping plate 37 to move in the reverse direction, and the clamping plate 37 no longer clamps the cloth winding cylinder 6. When the first hydraulic telescopic rod 21 drives the lifting seat 2 to move vertically, the first damping disc 5 at the winding station slides from one side of the first slider 7 to one side of the guide bar 10. When the cloth winding cylinder 6 and the first damping disc 5 move to the first loading and unloading station or the second loading and unloading station, the first damping disc 5 slides to one side of the second slider 9, and the second slider 9 is located in the corresponding sliding groove 8. At this time, the external manipulator moves to the lower part of the cloth winding cylinder 6 to be wound. The seventh hydraulic telescopic rod 57 drives the movable frame 58 and the second slider 9 to move relative to the frame 1. The second slider 9 drives the rotating shaft 4 and the mounting seat 34 to move away from the cloth winding cylinder 6 through the first damping disc 5. The translation seat 3 slides relative to the lifting seat 2, so that the end of the cloth winding cylinder 6 is separated from the receiving groove 35, and the positioning of the cloth winding cylinder 6 can be released. The external manipulator can then take out the cloth winding cylinder 6.

[0048] Embodiment 5, on the basis of Embodiment 2, by Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9A rotating sleeve 47 is externally rotatably sleeved on the support shaft 45.

A second compression spring 53 is sleeved on the outside of the arc-shaped strip 50, and the two ends of the second compression spring 53 are respectively abutted against the third slider 52 and the fourth slider 55. The sides of the third slider 52 and the fourth slider 55 away from the second compression spring 53 are in contact with the corresponding second support parts 48. A rotating plate 54 is fixedly connected to the fourth slider 55. A tension roller 11 is rotatably connected between the two rotating plates 54.

[0049] The polyester cloth passes through below the tension roller 11. When the support shaft 45 drives the first damping disc 5 to rotate through the first slider 7, the first damping disc 5 drives the second damping disc 51 and the third slider 52 to rotate relative to the support shaft 45 through friction. The third slider 52 applies pressure to the fourth slider 55 through the second compression spring 53. The rotating sleeve 47 and the rotating plate 54 rotate relative to the support shaft 45. The fourth slider 55 drives the tension roller 11 to press on the polyester cloth through the rotating plate 54. When the tension on the polyester cloth reaches the preset value, the first damping disc 5 slides relative to the second damping disc 51. When the cloth winding cylinder 6 rotates continuously, the tension on the polyester cloth can be kept at the preset value to ensure the winding quality. As the cloth winding cylinder 6 continuously winds, the polyester cloth comes into contact with the pressing strip 46, and the polyester cloth pushes the pressing strip 46 to slide relative to the prism 63. The tension spring 49 is in a stretched state, and the tension spring 49 applies a pulling force to the pressing strip 46. When the polyester cloth is cut off, the polyester cloth is pressed by the pressing strip 46 to prevent the polyester cloth from loosening relative to the cloth winding cylinder 6.

[0050] This embodiment further provides a winding process for polyester cloth, which is applied to the winding structure for polyester cloth as described above, and includes the following steps:

[0051] Step 1: Drive the cloth winding cylinder 6 located at the winding station to rotate through the driving assembly, wind the polyester cloth through the cloth winding cylinder 6, and stick double-sided tape on the surface of the cloth winding cylinder 6 located at the first loading and unloading station by an external manipulator or manually;

[0052] Step 2: When it is necessary to remove the cloth winding cylinder 6 at the winding station, cut the polyester cloth through the cutting and installation structure, and drive the lifting seat 2 and the translation seat 3 to move downward through the first hydraulic expansion rod 21, so that the cloth winding cylinder 6 at the winding station moves to the second loading and unloading station, and the cloth winding cylinder 6 at the first loading and unloading station moves to the winding station;

[0053] Step 3: Drive the end of the cut polyester cloth to move onto the double-sided tape through the cutting and installation structure, so that the end of the polyester cloth is fixedly connected to the cloth winding cylinder 6 at the winding station;

[0054] Step 4: Drive the cloth winding cylinder 6 at the winding station to rotate through the driving component, wind the polyester cloth through the cloth winding cylinder 6, and release the positioning and fixation of the cloth winding cylinder 6 at the second loading and unloading station through the positioning mechanism. Take away the cloth winding cylinder 6 whose positioning has been released by an external manipulator, and install a cloth winding cylinder 6 without wound polyester cloth.
