Description

Technical Field

[0001] This utility model relates to winding equipment, and in particular to a flip-type automatic winding receiving mechanism. Background Technology

[0002] Winding machines are common pieces of machinery in industrial production. To facilitate roll changing without stopping the machine after completing a round of winding, a tilting frame is usually used. During operation, one winding shaft winds the roll, while the other serves as a reserve roll. After the winding shaft finishes winding, the tilting frame flips, and the reserve roll continues winding. The completed roll is first transferred to the unloading station for unloading and placement of the new winding shaft, before rotating back to the reserve station. However, current tilting frames require precise control of the cutting and winding timings to ensure timely winding by the new winding shaft after material cutting, which can easily lead to errors. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flip-type automatic receiving and receiving mechanism. This flip-type automatic receiving and receiving mechanism can replace the receiving shaft when the winding is completed, and automatically complete the pre-receiving and cutting of materials during the replacement process, ensuring uninterrupted winding.

[0004] To solve the above technical problems, the following technical solution is adopted:

[0005] A flip-type automatic take-up and receiving mechanism includes a flip-up take-up frame, a first rotation drive device capable of driving the flip-up take-up frame to rotate, and at least two take-up shafts, both ends of each take-up shaft being rotatably mounted on the flip-up take-up frame. The mechanism is characterized by further including a cutter roller frame, a cutter roller frame drive device capable of driving the cutter roller frame to swing, a cutter roller, a cutter roller swing device capable of driving the cutter roller to swing, a pressure roller, and a pressure roller swing device capable of driving the pressure roller to swing. The cutter roller swing device and the pressure roller swing device are respectively mounted on the cutter roller frame. The cutter roller and the pressure roller are rotatably mounted on the cutter roller frame, and the pressure roller is positioned in front of the cutter roller along the conveying direction. The cutter roller is provided with transverse cutters extending along its length.

[0006] When the aforementioned flip-type automatic take-up and take-up mechanism is working, one take-up shaft on the flip-type take-up frame is in the take-up position for take-up, while a new take-up shaft is in the standby position waiting to be switched. When the take-up shaft finishes take-up, the flip-type take-up frame flips, and the new take-up shaft switches from the standby position to the take-up position. Subsequently, the cutter pressure roller frame drive device drives the cutter pressure roller frame to swing, so that the pressure roller and the cutter roller approach the new take-up shaft together. After the cutter pressure roller frame moves into position, the pressure roller, driven by the pressure roller swing device, presses the material onto the new take-up shaft, so that the new take-up shaft can take-up smoothly. At the same time, the cutter roller swing device drives the cutter roller to rotate, so that the transverse cutter flips from top to bottom to align with the material between the new and old take-up shafts, and cuts the material when it comes into contact with the material. After the material is cut and the new take-up shaft can take-up smoothly, the cutter pressure roller frame drive device drives the cutter pressure roller frame to lift up, away from the take-up shaft, and waits for the next take-up to repeat the above process. This flip-type automatic take-up and rewinding mechanism places the pressing and cutting functions on the cutter roller frame. During the flip-up rewinding process, the cutter roller frame does not obstruct the flip-up take-up frame. After flipping, the cutter roller frame promptly moves the pressure roller and cutter roller into position. Then, the pressure roller swing device and cutter roller swing device adjust the positions of the pressure roller and cutter roller respectively, ensuring that the pressure roller can smoothly press the material onto the new take-up shaft for pre-take-up. Furthermore, because the pressure roller is located in front of the cutter roller, it can separate the material being wound on the new take-up shaft from the material being cut on the old take-up shaft while pressing down. This allows the cutter roller to smoothly rotate the transverse cutter to the position where it contacts the material and completes the cutting without affecting the winding of the new take-up shaft. Precise control of the winding and cutting timing is not required, enabling smooth non-stop winding. The aforementioned cutter roller frame drive device can be a motor or a cylinder.

[0007] In a preferred embodiment, the cutter roller oscillation device includes a first oscillation drive mechanism capable of driving the first swing arm to oscillate and at least one first swing arm. The first oscillation drive mechanism is mounted on the cutter pressure roller frame. One end of the first swing arm is connected to the power output end of the first oscillation drive mechanism, and the other end of the first swing arm is fixedly connected to the cutter roller. During operation, the first oscillation drive mechanism drives the first swing arm to oscillate, thereby causing the cutter roller to rotate, and ultimately causing the transverse cutter to oscillate. Since the required rotation angle of the cutter roller in actual use is small, the oscillation angle of the transverse cutter is also relatively small. This structure allows for more precise control.

[0008] In a further preferred embodiment, there are two first swing arms. The first swing drive mechanism includes two first swing control cylinders, with each first swing arm corresponding to a first swing control cylinder. One end of each of the two first swing arms is fixedly mounted on both ends of the cutter roller. The cylinder body of the first swing control cylinder is hinged to the other end of the first swing arm or the cutter roller frame, and the piston rod of the first swing control cylinder is hinged to the cutter roller frame or the other end of the first swing arm. When the piston rod of the first swing control cylinder extends, it pushes the first swing arm to swing, thereby driving the cutter roller to rotate.

[0009] In a preferred embodiment, the pressure roller oscillation device includes a second oscillation drive mechanism capable of driving the second oscillation arm to oscillate and at least one second oscillation arm. The second oscillation arm is L-shaped. The second oscillation drive mechanism is mounted on the cutter pressure roller frame. The middle position of the second oscillation arm is hinged to the cutter pressure roller frame. One end of the second oscillation arm is drively connected to the power output end of the second oscillation drive mechanism, and the other end of the second oscillation arm is fixedly connected to the pressure roller. During operation, the second oscillation drive mechanism drives the second oscillation arm to oscillate, thereby causing the pressure roller to press down or lift up.

[0010] In a further preferred embodiment, there are two second swing arms. The second swing drive mechanism includes two second swing control cylinders, with each second swing arm corresponding to a different second swing control cylinder. One end of each second swing arm is fixedly mounted on both ends of the pressure roller. The cylinder body of the second swing control cylinder is hinged to the other end of the second swing arm or the cutter pressure roller frame, and the piston rod of the second swing control cylinder is hinged to the cutter pressure roller frame or the other end of the second swing arm. When the piston rod of the second swing control cylinder extends, it pushes the second swing arm to swing around the center position, thereby causing the pressure roller to press down or lift up.

[0011] In a preferred embodiment, the first rotation drive device includes a drive motor, a gear set, a worm gear, and a worm. The first-stage gear of the gear set is mounted on the power output shaft of the drive motor, the last-stage gear of the gear set is coaxially arranged with the worm, and the worm gear is coaxially arranged with the reversing winding frame, and the worm gear meshes with the worm. During roll changing, the drive motor drives the worm to rotate through the gear set, thereby driving the worm gear to rotate, ultimately causing the reversing winding frame to rotate.

[0012] The beneficial effects of this utility model are as follows: This flip-type automatic receiving and receiving mechanism can replace the receiving shaft when the winding is completed, and automatically completes pre-receiving and cutting during the replacement process, ensuring uninterrupted winding.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-3 The illustrated automatic reeling and receiving mechanism includes a flipping reeling frame 1, a first rotation drive device 2 capable of driving the flipping reeling frame 1 to rotate, a cutter pressure roller frame 3, a cutter pressure roller frame drive device 4 capable of driving the cutter pressure roller frame 3 to swing, a cutter roller 5, a cutter roller swing device 6 capable of driving the cutter roller 5 to swing, a pressure roller 7, a pressure roller swing device 8 capable of driving the pressure roller 7 to swing, and two take-up shafts 9. Both ends of each take-up shaft 9 can be rotatably mounted on the flipping reeling frame 1. The cutter roller swing device 6 and the pressure roller swing device 8 are respectively mounted on the cutter pressure roller frame 3. The cutter roller 5 and the pressure roller 7 are respectively rotatably mounted on the cutter pressure roller frame 3, and the pressure roller 7 is located in front of the cutter roller 5 along the conveying direction. The cutter roller 5 is provided with a transverse cutter 10 extending along the length direction.

[0018] When the aforementioned flip-type automatic take-up and take-up mechanism is working, one take-up shaft 9 on the flip-type take-up frame 1 is in the take-up position for take-up, while a new take-up shaft 9 is in the standby position waiting to be switched. When the take-up shaft 9 finishes take-up, the flip-type take-up frame 1 flips, and the new take-up shaft 9 switches from the standby position to the take-up position. Subsequently, the cutter pressure roller frame drive device 4 drives the cutter pressure roller frame 3 to swing, so that the pressure roller 7 and the cutter roller 5 move closer to the new take-up shaft 9. After the cutter pressure roller frame 3 moves into position, the pressure roller 7 is controlled by the pressure roller swing device 8. Driven by the material, the material is pressed onto the new take-up shaft 9, allowing the new take-up shaft 9 to be wound smoothly. At the same time, the cutter roller swing device 6 drives the cutter roller 5 to rotate, causing the transverse cutter 10 to flip from top to bottom and align with the material between the new take-up shaft 9 and the old take-up shaft 9, and cut the material when it comes into contact with the material. After the material is cut and the new take-up shaft 9 can be wound smoothly, the cutter pressure roller frame drive device 4 drives the cutter pressure roller frame 3 to lift up, away from the take-up shaft 9, and waits for the next take-up to repeat the above process. This flip-type automatic take-up and receiving mechanism sets both the pressing and cutting functions on the cutter roller frame 3. During the flip-up and rewinding process, the cutter roller frame 3 does not obstruct the flip-up take-up frame 1. After the flip-up is completed, the cutter roller frame 3 can promptly move the pressure roller 7 and the cutter roller 5 into position. Then, the pressure roller swing device 8 and the cutter roller swing device 6 adjust the positions of the pressure roller 7 and the cutter roller 5 respectively, ensuring that the pressure roller 7 can smoothly press the material onto the new take-up shaft 9 to achieve pre-take-up. Furthermore, since the pressure roller 7 is located in front of the cutter roller 5, when the pressure roller 7 is pressed down, it can separate the take-up of the new take-up shaft 9 from the material cutting of the old take-up shaft 9. This allows the cutter roller 5 to smoothly rotate the transverse cutter 10 to the position where it contacts the material and complete the material cutting without affecting the take-up of the new take-up shaft 9. There is no need to precisely control the timing of take-up and cutting, and take-up can be successfully achieved without stopping the machine.

[0019] The cutter roller oscillation device 6 includes a first oscillation drive mechanism 601 capable of driving the first swing arm 602 to oscillate, and two first swing arms 602. The first oscillation drive mechanism 601 is mounted on the cutter pressure roller frame 3. One end of the first swing arm 602 is connected to the power output end of the first oscillation drive mechanism 601, and the other end of the first swing arm 602 is fixedly connected to the cutter roller 5. During operation, the first oscillation drive mechanism 601 drives the first swing arms 602 to oscillate, thereby driving the cutter roller 5 to rotate, and ultimately driving the transverse cutter 10 to oscillate. Since the required rotation angle of the cutter roller 5 in actual use is not large, the oscillation angle of the transverse cutter 10 is also not large. This structure allows for more precise control.

[0020] The first swing drive mechanism 601 includes two first swing control cylinders. A first swing arm 602 corresponds one-to-one with each first swing control cylinder. One end of each first swing arm 602 is fixedly mounted on both ends of the cutter roller 5. The cylinder body of the first swing control cylinder is hinged to the cutter pressure roller frame 3, and the piston rod of the first swing control cylinder is hinged to the other end of the first swing arm 602. When the piston rod of the first swing control cylinder extends, it pushes the first swing arm 602 to swing, thereby driving the cutter roller 5 to rotate.

[0021] The pressure roller oscillation device 8 includes a second oscillation drive mechanism 801 capable of driving the second oscillation arm 802 to oscillate, and two second oscillation arms 802. The second oscillation arms 802 are L-shaped. The second oscillation drive mechanism 801 is mounted on the cutter pressure roller frame 3. The middle position of the second oscillation arm 802 is hinged to the cutter pressure roller frame 3. One end of the second oscillation arm 802 is connected to the power output end of the second oscillation drive mechanism 801, and the other end of the second oscillation arm 802 is fixedly connected to the pressure roller 7. During operation, the second oscillation drive mechanism 801 drives the second oscillation arm 802 to oscillate, thereby causing the pressure roller 7 to press down or lift up.

[0022] The second swing drive mechanism 801 includes two second swing control cylinders. A second swing arm 802 corresponds one-to-one with each second swing control cylinder. One end of each second swing arm 802 is fixedly mounted on both ends of the pressure roller 7. The cylinder body of the second swing control cylinder is hinged to the cutter pressure roller frame 3, and the piston rod of the second swing control cylinder is hinged to the other end of the second swing arm 802. When the piston rod of the second swing control cylinder extends, it pushes the second swing arm 802 to swing around the center position, thereby causing the pressure roller 7 to press down or lift up.

[0023] The first rotation drive device 2 includes a drive motor 201, a gear set 202, a worm gear 203, and a worm (not shown in the figure). The first stage gear of the gear set 202 is mounted on the power output shaft of the drive motor 201, and the last stage gear of the gear set 202 is coaxially arranged with the worm. The worm gear 203 is coaxially arranged with the reversing winding frame 1, and the worm gear 203 meshes with the worm. When changing rolls, the drive motor 201 drives the worm to rotate through the gear set 202, thereby driving the worm gear 203 to rotate, ultimately causing the reversing winding frame 1 to rotate.
