The tail end of the feeding cylinder 9-2 is connected to the fixed bracket 9-1, and the piston rod end of the feeding cylinder 9-2 is connected to the ear seat below the flip frame 9-4. The feeding cylinder 9-2 pushes to flip the flip frame 9-4 along the flip rotary shaft 9-10. The upper end of the flip frame 9-4 is connected to the swing cylinder 9-5; the upper part of the swing cylinder 9-5 is connected to the receiving plate 9-6. The ventilation of the swing cylinder 9-5 can drive the receiving plate 9-6 to rotate 180°. There are multiple pallets 9-8, and the multiple pallets 9-8 are arranged vertically in parallel, such as four pallets 9-8 connected into a whole, and connected to the pallet bearing seat 9-9 through the flip rotation shaft 9-10, and the pallet bearing seat 9-9 is fixed to the fixed bracket 9-1. The tail end of the material receiving cylinder 9-3 is connected to the fixed bracket 9-1, and the piston rod end of the material receiving cylinder 9-3 is connected to the pallet 9-8. The roller conveyor 9-11 is connected to the fixed bracket 9-1, and the roller conveyor 9-11 has multiple conveying rollers arranged in parallel, and there is a gap between two adjacent conveying rollers. The thickness of the pallet 9-8 is smaller than the gap width between two adjacent conveying rollers, so that the pallet 9-8 can pass through the gap between two adjacent rollers when swinging in the vertical plane. When the receiving cylinder 9-3 is pushed, the support plate 9-8 can be driven to swing. The support plate 9-8 can extend from the gap between two adjacent conveying rollers to the top of the conveying roller. The side edges of multiple support plates 9-8 are located in the same plane, which can form a supporting surface for supporting the silk cake 11; when the receiving cylinder 9-3 is retracted, the support plate 9-8 falls under the conveying roller of the roller conveyor 9-11, so that the silk cake 11 falls vertically onto the conveying roller of the roller conveyor 9-11 for transportation to the next process.

[0065] Before working, the feeding cylinder 9-2 and the receiving cylinder 9-3 are both in the retracted state, the support plate 9-8 is located below the conveying roller of the roller conveyor 9-11, and the receiving surface of the receiving plate 9-6 is in a horizontal state. When there is a silk cake 11 on the receiving plate 9-6, the receiving cylinder 9-3 extends out and drives the support plate 9-8 to swing above the roller conveyor 9-11 until the support plate 9-8 swings to the specified position above the conveying roller of the roller conveyor 9-11; the feeding cylinder 9-2 extends out and drives the receiving plate 9-6 to rotate obliquely to one side of the roller conveyor 9-11, gradually lifting the silk cake 11 from a horizontal state to an inclined state. When the end face of the inclined silk cake 11 contacts the support plate 9-8 that has swung into place, the receiving cylinder 9-3 is slowly retracted, and the support plate 9-8 swings back to the bottom of the conveying roller of the roller conveyor 9-11. Under the action of gravity, the end face of the silk cake 11 contacts the conveying roller of the roller conveyor 9-11, and the silk cake 11 becomes vertical. The feeding cylinder 9-2 is retracted, and the receiving plate 9-6 is reset to complete the flipping and vertical action of the silk cake 11.

[0066] In addition, there are some silk cakes 11 on site that do not need to be wrapped with film, but need to be bagged. At this time, the silk cake automatic film wrapping machine only plays a role of transportation. When the six-axis manipulator takes the bagged silk cake 11 from the yarn car and puts it on the film wrapping machine, the end face opening direction is exactly opposite to the film wrapping opening. At this time, the swing cylinder 9-5 needs to rotate 180° during the flipping and erecting action, so that when the silk cake 11 falls on the roller conveyor 9-11, it is always in a state where the film wrapping opening is facing upward.

[0067] In the bottom tapping process, the portion of the packaging film that extends beyond the axial length of the silk cake is flattened along the end surface of the silk cake through two squeezing actions of the bottom tapping mechanism 8. However, the squeezed film is not flat on the end surface of the silk cake, and will still form an inward depression at the end surface of the silk cake, that is, the film will bend toward the inside of the silk cake. When the yarn is unwound in the silk cake, it is possible that the yarn will rub against the raised film, affecting the quality of the yarn and forming hairy yarns. Therefore, it is necessary to flatten the raised film inside the silk cake to prevent friction with the yarn. Therefore, in this embodiment, after the silk cake 11 is turned over and erected, the bottom film flattening mechanism 10 is used to squeeze and flatten the film that is concave inward on the end surface of the silk cake 11.

[0068] In this embodiment, the automatic film wrapping machine for silk cakes further comprises a bottom film flattening mechanism 10. Specifically, FIG. 10A to FIG. 10BAs shown, the bottom film flattening mechanism 10 includes a bottom film pressing plate 10-1, a fixed clamping plate 10-2, a movable clamping plate 10-3, a sensor 10-4, a clamping plate cylinder and a clamping plate cylinder. A connecting rod is vertically provided on the upper part of the bottom film pressing plate 10-1, and the connecting rod is connected to the clamping plate cylinder. The piston rod of the clamping plate cylinder extends to drive the bottom film pressing plate 10-1 to move downward to squeeze the end surface of the wire cake 11. The movable clamping plate 10-3 is connected to the clamping plate cylinder, and the piston rod of the clamping plate cylinder extends to drive the movable clamping plate 10-3 to move to the left. The movable clamping plate 10-3 cooperates with the fixed clamping plate 10-2 to clamp the wire cake 11. The axis of the clamped wire cake 11 coincides or approximately coincides with the axis of the bottom film pressing plate 10-1. The sensor 10-4 is used to detect whether the wire cake 11 reaches the set position, and transmits the wire cake in place signal to the electrical control unit. The electrical control unit controls the action of the clamping plate cylinder and the clamping plate cylinder based on the set program.

[0069] In one of the optional embodiments, the bottom film pressing plate 10 - 1 has a heating function and can be heated by powering on or other means, thereby achieving a better effect on flattening the bottom film.

[0070] During operation, after the sensor 10-4 detects that the silk cake 11 has reached the set position, the electrical control unit controls the clamping plate cylinder to extend, driving the movable clamping plate 10-3 to move toward the fixed clamping plate 10-2, and the movable clamping plate 10-3 and the fixed clamping plate 10-2 together fix the silk cake 11; the electrical control unit controls the pressing plate cylinder to extend, driving the bottom film pressing plate 10-1 to press down, and flattening the film that is concave inward at the rear end of the bottom beating process.

[0071] This embodiment is provided with a bottom film flattening mechanism 10, which can flatten the film that is recessed inside the silk cake 11 at the end surface of the silk cake 11 after the bottom tapping process, to prevent the yarn from rubbing against the recessed film to produce hair when the silk cake 11 is unwound.

[0072] The specific action flow of the automatic film wrapping machine for silk cakes is as follows:

[0073] 1. Preparation: Install the packaging film 6-4 for silk cake on the tension mechanism 6, and use the film cutting mechanism 4 to perform the initial film cutting. Specifically, manually place the packaging film 6-4 for silk cake on the air expansion shaft 6-3 of the tension mechanism 6, and manually pull the film through the redirection frame 6-5 to the film cutting mechanism 4, press the switch, and the clamping plate 4-6 opens. Spread the film flat on the support plate 4-9, press the switch again, the clamping plate 4-6 closes, and the film cutting cylinder 4-7 moves to complete the initial film clamping and film cutting action. Manually remove the excess film after film cutting.

[0074] 2. The six-axis manipulator places the silk cake 11 on the rubber-coated roller 5-4 of the film wrapping mechanism 5, and transmits the measured diameter signal to the electrical control unit, which controls the film wrapping mechanism 5 to wrap the film around the silk cake 11. Specifically, the electrical control unit adjusts the program, the film clamping cylinder 4-2 is retracted, and the clamping plate 4-6 is opened. The rocker motor 5-2 rotates, driving the electric slide 5-3 to rotate. During the rotation, the rocker 5-5 always moves along the outer cylindrical surface of the silk cake 11 according to the set program; after the rocker 5-5 is in place, the film wrapping motor 5-6 rotates, driving the silk cake 11 to rotate, and rotates the set number of circles according to the set program. At the same time, the electric slide 5-3 returns to the initial position. In the process of the electric slide 5-3 returning to the initial position, the slider 4 of the electric slide 5-3 moves to the farthest end.

[0075] 3. After the silk cake 11 is wrapped on the film wrapping mechanism 5, the transfer mechanism 2 moves the silk cake 11 to the rewinding mechanism 3. Specifically, after the silk cake is wrapped on the film wrapping mechanism 5, the lifting cylinder 2-13 of the transfer mechanism 2 extends to lift the silk cake 11; the transfer motor 2-2 rotates to drive the silk cake 11 to move horizontally to the rewinding mechanism 3; the lifting cylinder 2-13 is retracted to make the silk cake 11 fall on the two rollers of the rewinding mechanism 3 and return to the initial position.

[0076] 4. The film cutting mechanism 4 presses and cuts the film, and the silk cake 11 is rewound on the rewinding mechanism 3, and the cut film tail is wound on the silk cake 11 to complete the finishing. Specifically, the film clamping cylinder 4-2 of the film cutting mechanism 4 extends, the film clamping is completed, the film cutting cylinder 4-7 is actuated, and the film cutting action is completed; at the same time, the yarn pressing cylinder 7-2 of the yarn pressing mechanism 7 extends, so that the yarn pressing roller 7-4 presses the outer peripheral surface of the silk cake 11. The driving roller 3-3 rotates, driving the silk cake 11 to rotate, and the film tail of the silk cake 11 to the yarn cutting mechanism 4 is wound on the silk cake 11 to complete the finishing.

[0077] 5. The bottom tapping mechanism 8 performs the bottom tapping process, flattening the portion of the packaging film that exceeds the axial length of the silk cake along the end surface of the silk cake. The two bottom tapping cylinders 8-2 extend and retract in sequence, flattening the film that exceeds the length of the silk cake 11 along the end surface of the silk cake 11, completing the bottom tapping.

[0078] 6. The yarn pressing cylinder 7-2 of the yarn pressing mechanism 7 is retracted, and the yarn unloading cylinder 3-6 of the rewinding mechanism 3 is extended to lift the yarn cake 11, and the yarn cake 11 is rolled to the receiving plate 9-6 of the flipping and erecting mechanism 9 by the gravity of the yarn cake 11.

[0079] 7. The flipping and erecting mechanism 9 performs the flipping and erecting process, flips the silk cake 11 after the bottom-patting process to a vertical state, and conveys the flipped and erected silk cake 11 to the next process. Specifically, the receiving cylinder 9-3 extends, and after the support plate 9-8 swings into place, the feeding cylinder 9-2 extends to lift the silk cake 11 to an inclined state. After the end surface of the silk cake 11 contacts the support plate 9-8, the receiving cylinder 9-3 slowly retracts. Under the action of gravity, the end surface of the silk cake 11 contacts the roller conveyor 9-11, and the feeding cylinder 9-2 retracts, completing the flipping and erecting action of the silk cake 11.

[0080] 8. After the silk cake 11 is turned over and erected, the bottom film flattening mechanism 10 is used to flatten the film that is concave inward on the end surface of the silk cake 11 to complete the film wrapping of the silk cake. Specifically, when the sensor 10-4 detects that the silk cake 11 has reached the set position, the clamping plate cylinder extends to fix the movable clamping plate 10-3 and the fixed clamping plate 10-2 to clamp the silk cake 11. The pressing plate cylinder extends to press the bottom film pressing plate 10-1 down to the end surface of the silk cake, and after maintaining the predetermined time t, such as t is 3-10 seconds, the pressing plate cylinder is retracted, the clamping plate cylinder is retracted, and the conveyor below continues to operate to transport the silk cake 11 to the next process.

[0081] Furthermore, when the transplanting mechanism 2 places the silk cake 11 on the rewinding mechanism 3, the six-axis manipulator can place the next silk cake 11 on the film wrapping mechanism 5, and the two workstations can be carried out synchronously, which greatly shortens the work cycle and improves work efficiency.

[0082] Compared with the prior art, the automatic silk cake wrapping machine provided in this embodiment uses an electrical control unit to control the automatic working process of the transplanting mechanism, the rewinding mechanism, the film cutting mechanism, the film wrapping mechanism, the tension mechanism, the yarn pressing mechanism, the bottom patting mechanism, the flipping and erecting mechanism, and the bottom film flattening mechanism, so as to realize automatic film wrapping with a fast film wrapping speed and liberate the labor in the film wrapping process; and when the transplanting mechanism places the silk cake on the rewinding mechanism, the six-axis robot can place the next silk cake on the film wrapping mechanism, and the two workstations can be carried out synchronously, which greatly shortens the film wrapping time and significantly improves production efficiency.

It should be understood that the above description is only the specific implementation method of the present application and is not intended to limit the scope of protection of the present application.
