Description

Technical Field

[0001] This utility model relates to the technical field of take-up roller mechanisms, specifically a take-up roller mechanism for polyester fabric. Background Technology

[0002] Polyester fabric (polyester fiber) is a synthetic fiber material processed from petrochemical products. It has high strength, abrasion resistance, and corrosion resistance, and is widely used in clothing, decoration, and industrial fields. After the polyester fabric is produced, it needs to be wound up. The winding mechanism is the material receiving part of the fabric processing production line. During winding, it is mainly used to mechanically wind the fabric into a roll. During the winding process, it is difficult to control the tension of the roll, which often leads to changes in the tightness of the roll during winding. In severe cases, it can further lead to unequal surface diameters of the roll, posing a risk of the roll collapsing due to loose winding. In order to better wind up polyester fabric, a polyester fabric winding roller mechanism is proposed.

[0003] As disclosed in the patent announcement CN218434284U, a composite fabric take-up roller includes a main body, a fixed flattening mechanism, and a locking mechanism. The fixed flattening mechanism is located at the upper end of the main body, and the locking mechanism is located at the front end of the main body. The main body includes a rubber roller, a mirror roller, a connecting end, a mounting screw hole, a mounting threaded connection, a movable mounting shaft, and a slot. The mirror roller is fixedly installed at the upper end of the rubber roller, the connecting end is fixedly installed at the front end of the rubber roller, the mounting screw hole is fixedly installed inside the connecting end, and the mounting threaded connection is movably installed inside the mounting screw hole.

[0004] Although it realizes the composite fabric take-up roller, it improves the anti-wrinkle ability of the composite fabric take-up roller. In actual use, the fabric to be taken up can be conveniently fixed on the take-up roller without wrinkles or deviation due to speed, thus improving the practicality of the composite fabric take-up roller.

[0005] However, the existing winding roller mechanism does not solve the problem that it is not conducive to automatically placing the input clamping and fixing hollow winding roller and outputting the wound polyester fabric roll during use, and it is not conducive to maintaining the elastic tension of the polyester fabric at all times, which affects the convenience and quality of winding the polyester fabric. Utility Model Content

[0006] The purpose of this utility model is to provide a polyester fabric take-up roller mechanism to solve the problems mentioned in the background art, such as the inconvenience of automatically placing the input clamping and fixing hollow take-up roller and outputting the finished polyester fabric roll, which is not conducive to maintaining the elastic tension of the polyester fabric at all times, thus affecting the convenience and quality of polyester fabric take-up.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a polyester fabric take-up roller mechanism, including a base and a limiting frame. The limiting frame is provided at the top of the base, and two sets of support frames are provided at the top of the base on one side of the limiting frame. A hydraulic cylinder is provided at the top of the base on one side of the support frame, and a first push arm is installed at the output end of each hydraulic cylinder. A support block is installed at the top of each first push arm, and an arc-shaped block is installed at the top of each support block. A hollow take-up roller is provided between the two sets of support frames. A movable shaft is movably arranged inside each support frame, and a first servo motor is provided on the outer wall of one set of support frames. The output end of the first servo motor is connected to a set of movable shafts. An electric push rod is provided inside each movable shaft, and a second push arm is installed at the output end of each electric push rod.

[0008] Furthermore, each end of the second push arm away from the electric push rod is provided with a moving block, and each moving block has three sets of linkage arms at equal intervals on its side wall.

[0009] Furthermore, each of the linkage arms is provided with a connecting shaft at one end near the moving block, and the linkage arm is movably connected to the moving block through the connecting shaft.

[0010] Furthermore, each of the linkage arms is provided with a clamping arm at the end away from the moving block, and each of the clamping arms is provided with a hinge shaft at the end near the linkage arm, and the clamping arm is movably connected to the linkage arm through the hinge shaft.

[0011] Furthermore, each of the clamping arms is provided with a pin on its side wall, and the clamping arms are movably connected to the movable shaft through the pin.

[0012] Furthermore, the base is internally provided with a bidirectional lead screw, which is movably connected to the base.

[0013] Furthermore, a second servo motor is provided on the outer wall of the base, and the output end of the second servo motor is connected to a bidirectional lead screw.

[0014] Furthermore, the surface of the bidirectional lead screw is fitted with two sets of threaded sleeves, and the threaded sleeves are threadedly connected to the bidirectional lead screw, and the threaded sleeves are respectively connected to the support frame.

[0015] Furthermore, the limiting frame is provided with two sets of limiting blocks inside, and the limiting blocks are slidably connected to the limiting frame.

[0016] Furthermore, each of the limiting blocks is provided with a spring at its top, and the spring is connected to the limiting frame, and a limiting roller is movably arranged between the two sets of limiting blocks.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the winding roller mechanism not only realizes the automatic placement of the input clamping and fixing of the hollow winding roller and the output of the wound polyester fabric roll, which facilitates the maintenance of elastic tension of the polyester fabric at all times, but also improves the convenience and quality of winding the polyester fabric.

[0018] The hollow take-up roller is placed above the arc-shaped block. A hydraulic cylinder drives the first push arm upwards, which in turn moves the bearing block upwards. The bearing block then moves the arc-shaped block and the hollow take-up roller upwards, aligning the centerline of the hollow take-up roller with the centerline of the movable shaft. A second servo motor drives a bidirectional lead screw to rotate, which, through a threaded sleeve, moves two sets of bearing frames closer together. The bearing frames then drive the movable shaft to insert into the hollow take-up roller. An electric push rod moves the second push arm, which in turn moves a moving block. The moving block, through a connecting shaft, drives a linkage arm to rotate. The linkage arm, through a hinge shaft, drives a clamping arm to rotate around a pin, causing all three clamping arms to rotate outwards synchronously until they contact the inner wall of the hollow take-up roller. The clamping arms then hold and fix the hollow take-up roller to the surface of the movable shaft. After the hollow take-up roller is clamped, the hydraulic cylinder is operated... The arc-shaped block is reset, and then the polyester fabric is pulled through the lower surface of the limiting roller to the surface of the hollow take-up roller and fixed on the hollow take-up roller. The first servo motor drives a set of movable shafts to rotate, and the movable shafts drive the hollow take-up roller to rotate through the clamping arms. The hollow take-up roller then winds up the polyester fabric. After the fabric is wound up, the hydraulic cylinder drives the arc-shaped block to move upward and contact the surface of the hollow take-up roller. The second servo motor and the electric push rod are opened in the opposite direction. The electric push rod drives the clamping arms to reset, and the second servo motor drives the two sets of carrier frames to move away from each other and drives the movable shaft to be pulled out from inside the hollow take-up roller. The hollow take-up roller with polyester fabric attached to its surface falls onto the surface of the arc-shaped block to complete the winding of the polyester fabric. This realizes the automatic placement, input, clamping and fixing of the hollow take-up roller and output of the wound polyester fabric roll, improving the convenience of winding polyester fabric.

[0019] As the polyester fabric moves during winding, the sliding contact between the fabric and the limiting roller causes the limiting roller to move upward. The limiting roller then moves the limiting block upward within the limiting frame. The limiting block compresses the spring, and the elastic contact of the spring causes the limiting block to move downward continuously. This, in turn, causes the limiting roller to move downward continuously, thus pressing down on the polyester fabric. This keeps the polyester fabric taut, ensuring smooth winding and improving the quality of the polyester fabric winding. Attached Figure Description

[0035] Please see Figures 1 to 6 This utility model provides an embodiment of a polyester fabric take-up roller mechanism, including a base 1 and a limiting frame 3. The limiting frame 3 is located at the top of the base 1. Two sets of support frames 2 are located at the top of the base 1 on one side of the limiting frame 3. Hydraulic cylinders 5 are located at the top of the base 1 on one side of each support frame 2. A first push arm 6 is installed at the output end of each hydraulic cylinder 5. A support block 7 is installed at the top of each first push arm 6. An arc-shaped block 8 is installed at the top of each support block 7. A hollow take-up roller 4 is located between the two sets of support frames 2. A movable shaft 9 is movably installed inside each support frame 2. A first servo motor 10 is installed on the outer wall of the support frame 2, and the output end of the first servo motor 10 is connected to a set of movable shafts 9. Each movable shaft 9 is equipped with an electric push rod 17. Each electric push rod 17 is equipped with a second push arm 18 at its output end. Each second push arm 18 is equipped with a moving block 19 at the end away from the electric push rod 17. Each moving block 19 is equipped with three sets of linkage arms 20 at equal intervals on its side wall. Each linkage arm 20 is equipped with a connecting shaft 24 at the end near the moving block 19, and the linkage arm 20 is movably connected to the moving block 19 through the connecting shaft 24.

[0036] Each end of the linkage arm 20 away from the moving block 19 is provided with a clamping arm 23, and each end of the clamping arm 23 near the linkage arm 20 is provided with a hinge shaft 21, and the clamping arm 23 is movably connected to the linkage arm 20 through the hinge shaft 21.

[0037] Pins 22 are provided on the side walls of the clamping arms 23, and the clamping arms 23 are movably connected to the movable shaft 9 through the pins 22.

[0038] The base 1 has a bidirectional lead screw 14 inside, and the bidirectional lead screw 14 is movably connected to the base 1. The outer wall of the base 1 has a second servo motor 16, and the output end of the second servo motor 16 is connected to the bidirectional lead screw 14.

[0039] Two sets of threaded sleeves 15 are fitted on the surface of the bidirectional lead screw 14, and the threaded sleeves 15 are threadedly connected to the bidirectional lead screw 14, and the threaded sleeves 15 are respectively connected to the bearing frame 2.

[0040] When it is necessary to wind up the polyester fabric, the hollow winding roller 4 is placed above the arc-shaped block 8. The hydraulic cylinder 5 is activated, which drives the first push arm 6 to move upward. The first push arm 6 drives the bearing block 7 to move upward, which in turn drives the arc-shaped block 8 and the hollow winding roller 4 to move upward, so that the center line of the hollow winding roller 4 is aligned with the center line of the movable shaft 9. Then, the second servo motor 16 is activated, which drives the bidirectional lead screw 14 to rotate. With the bidirectional lead screw 14 threadedly connected to the threaded sleeve 15, the bidirectional lead screw 14 rotates through the threaded sleeve 15. The sleeve 15 drives the two sets of support frames 2 to move closer to each other. The support frame 2 drives the movable shaft 9 to insert into the interior of the hollow take-up roller 4. The electric push rod 17 is opened, and the electric push rod 17 drives the second push arm 18 to move. The second push arm 18 drives the moving block 19 to move. The moving block 19 drives the linkage arm 20 to rotate through the connecting shaft 24. The linkage arm 20 drives the clamping arm 23 to rotate around the pin 22 through the hinge shaft 21, so that the three sets of clamping arms 23 rotate outward synchronously, so that the clamping arms 23 contact the inner wall of the hollow take-up roller 4, and the clamping arms 23 clamp and fix the hollow take-up roller 4. After the hollow take-up roller 4 clamps the fabric on the surface of the movable shaft 9, the hydraulic cylinder 5 drives the arc block 8 to reset. Then, the polyester fabric is pulled from the lower surface of the limit roller 12 to the surface of the hollow take-up roller 4 and fixed on the hollow take-up roller 4. The first servo motor 10 is turned on, and the first servo motor 10 drives a set of movable shafts 9 to rotate. With the cooperation of another set of movable shafts 9, the movable shafts 9 drive the hollow take-up roller 4 to rotate through the clamping arm 23. The hollow take-up roller 4 then winds up the polyester fabric. After the fabric is wound up, the hydraulic cylinder 5 is turned on again. The arc-shaped block 8 moves upward and contacts the surface of the hollow take-up roller 4, opening the second servo motor 16 and the electric push rod 17 in the reverse direction. The electric push rod 17 drives the clamping arm 23 to reset, and the second servo motor 16 drives the two sets of support frames 2 to move away from each other and drives the movable shaft 9 to be pulled out from inside the hollow take-up roller 4. The hollow take-up roller 4 with polyester fabric attached to its surface falls onto the surface of the arc-shaped block 8 to complete the take-up of the polyester fabric. This realizes the automatic placement, input, clamping and fixing of the hollow take-up roller and the output of the finished polyester fabric roll, improving the convenience of polyester fabric take-up.

[0041] The limiting frame 3 has two sets of limiting blocks 11 inside, and the limiting blocks 11 are slidably connected to the limiting frame 3. The top of each limiting block 11 is provided with a spring 13, and the spring 13 is connected to the limiting frame 3. A limiting roller 12 is movably arranged between the two sets of limiting blocks 11.

[0042] When the polyester fabric is wound up, it will move. With the sliding cooperation between the fabric and the limiting roller 12, the fabric drives the limiting roller 12 to move upward. With the sliding cooperation between the limiting block 11 and the limiting frame 3, the limiting roller 12 drives the limiting block 11 to move upward inside the limiting frame 3. The limiting block 11 compresses the spring 13. With the elastic cooperation of the spring 13, the spring 13 drives the limiting block 11 to move downward continuously. Thus, the limiting block 11 drives the limiting roller 12 to move downward continuously. The limiting roller 12 presses down on the polyester fabric to keep the polyester fabric taut, thereby ensuring the smoothness of the polyester fabric during winding and improving the quality of polyester fabric winding.

[0043] Working principle: When polyester fabric needs to be wound up, the hollow take-up roller 4 is placed above the arc-shaped block 8. The hydraulic cylinder 5 drives the first push arm 6 to move upward, which in turn drives the bearing block 7 to move upward. The bearing block 7 then drives the arc-shaped block 8 and the hollow take-up roller 4 to move upward, so that the center line of the hollow take-up roller 4 is aligned with the center line of the movable shaft 9. The second servo motor 16 drives the bidirectional lead screw 14 to rotate. The bidirectional lead screw 14, through the threaded sleeve 15, drives the two sets of bearing frames 2 to move closer to each other. The bearing frames 2 drive the movable shaft 9 to insert into the interior of the hollow take-up roller 4. The electric push rod 17 drives the second The push arm 18 moves, driving the moving block 19 to move. The moving block 19 drives the linkage arm 20 to rotate via the connecting shaft 24. The linkage arm 20 drives the clamping arm 23 to rotate around the pin 22 via the hinge shaft 21, causing the three clamping arms 23 to rotate outward synchronously. This makes the clamping arms 23 contact the inner wall of the hollow take-up roller 4, clamping and fixing the hollow take-up roller 4 to the surface of the movable shaft 9. After the hollow take-up roller 4 is clamped, the hydraulic cylinder 5 is operated to drive the arc block 8 to reset. Then, the polyester fabric is pulled through the lower surface of the limit roller 12 to the surface of the hollow take-up roller 4 and fixed thereon. The first servo motor 10 drives a set of movable shafts 9 to rotate. The movable shafts 9 drive the hollow take-up roller 4 to rotate via the clamping arm 23. The hollow take-up roller 4 takes up the polyester fabric. After the fabric is finished being taken up, the hydraulic cylinder 5 is opened again. The hydraulic cylinder 5 drives the arc block 8 to move upward and contact the surface of the hollow take-up roller 4. The second servo motor 16 and the electric push rod 17 are opened in the opposite direction. The electric push rod 17 drives the clamping arm 23 to reset. The second servo motor 16 drives the two sets of support frames 2 to move away from each other and drives the movable shaft 9 to be pulled out from inside the hollow take-up roller 4. The hollow take-up roller 4 with polyester fabric attached to its surface falls down. The polyester fabric is wound up on the surface of the arc-shaped block 8. The polyester fabric moves during winding. With the sliding cooperation between the fabric and the limiting roller 12, the fabric drives the limiting roller 12 to move upward. The limiting roller 12 drives the limiting block 11 to move upward inside the limiting frame 3. The limiting block 11 squeezes the spring 13. With the elastic cooperation of the spring 13, the spring 13 drives the limiting block 11 to move downward. Thus, the limiting block 11 drives the limiting roller 12 to move downward. The limiting roller 12 presses down on the polyester fabric to keep the polyester fabric taut and ensure the smoothness of the polyester fabric during winding.
