Description
Technical fields:
[0001] This utility model relates to the field of yarn manufacturing and processing technology, and more specifically to an automatic loading and unloading mechanism for a yarn drawing frame. Background technology:
[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments, reducing weight unevenness, straightening and paralleling the fibers in the sliver, reducing hooks, ensuring the fineness meets the requirements, and mixing different types or qualities of raw materials evenly to achieve the specified mixing ratio.
[0003] It requires winding the yarn into the corresponding material cylinder, which is then placed at the receiving position below the main body of the yarn doubling machine. Existing material cylinders all require manual feeding and unloading. Since the material cylinder is located below the main body of the yarn doubling machine, the operating space is small, making loading and unloading inconvenient and prone to causing the operator's head to bump. Utility Model Content:
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic loading and unloading mechanism for yarn drawing frames. It can automatically load and unload the material cylinder, has a high degree of automation, and greatly reduces manual labor.

The output shaft of the rotary servo motor is inserted into the central through hole formed in the middle of the bottom surface of the central recessed hole. A rotating plate is fixed to the top of the output shaft of the rotary servo motor. The bottom surface of the material cylinder presses against the top surface of the rotating plate.
[0010] The front wall of the push block has a front arc-shaped groove formed in the middle, which corresponds to the rear wall of the material cylinder. A rear guide rod is fixed on the rear wall of the push block, and the rear guide rod is inserted into the guide through hole formed on the connecting plate.

[0024] The middle of the rear part of the opposite wall of the two front support blocks 30 is formed with mounting grooves. The limit rotation servo motor 31 is located in the mounting groove and fixed on the bottom surface of the mounting groove. A swing arm 32 is fixed on the rotating shaft of the limit rotation servo motor 31. One end of the swing arm 32 that extends out of the mounting groove is movably connected to a guide wheel 33 through a hinge shaft. The guide wheel 33 is close to the front wall of the corresponding material cylinder 100.
[0025] The other end of the swing arm 32 is close to the sensing end of the first proximity switch 4 fixed on the inner side wall of the mounting groove and is sensed by it.
[0026] A second proximity switch 5 is fixed in the middle of the rear wall of the mounting groove, which corresponds to one end of the swing arm 32.

A limit block 35 is fixed on the inner sidewall of the middle part of the elongated groove 34, and the swing arm 32 corresponds to the sidewall of the limit block 35.
[0028] Furthermore, a mounting groove is formed in the middle of the front wall of the rear support plate 12 at the outer side of the material cylinder placement position. The horizontally arranged rodless cylinder 15 is located in the mounting groove and fixed on the inner side wall of the mounting groove. A push plate 16 is fixed on the moving block of the rodless cylinder 15. A side push block 17 is fixed on the side wall of the push plate 16 facing the corresponding material cylinder placement position. A side groove is formed on the side wall of the side push block 17. The corresponding side wall of the material cylinder 100 is located in the side groove and is in close contact with the side self-lubricating layer 171 fixed on the inner side wall of the side groove.
[0029] The middle support block 111 is fixed in the middle of the left and right side walls of the intermediate support plate 11. The side wall of the intermediate support block 111 is fixed with an inner self-lubricating layer 112. The corresponding side of the corresponding material cylinder 100 is tightly attached to the corresponding inner self-lubricating layer 112.
[0030] A transversely extending self-lubricating transverse block 2 is fixed on the front wall of the rear support plate 12 directly below the rodless cylinder 15, and the rear wall of the material cylinder 100 corresponds to the front wall of the corresponding self-lubricating transverse block 2.

[0032] In this embodiment, the bottom of the material cylinder 100 is equipped with rollers for easy movement; all electrical components in this embodiment are electrically connected to the control host through electrical connection lines and are controlled by the control host. The cylinders are all connected to the pneumatic system through connecting pipes. The air pump, solenoid valve and other components in the pneumatic system are also electrically connected to the control host through electrical connection lines. This is a conventional structure and will not be described in detail here.
[0033] In this embodiment, the material cylinder 100 is first manually pushed into the feed port between the front support block 30 and the side baffle 121 (there are no obstructing parts above, the operating space is large, and it is convenient for manual placement). Then, it is placed against the front wall of the corresponding self-lubricating transverse block 2 and facing the side push block 17. Then, the moving block of the corresponding rodless cylinder 15 moves, causing the side push block 17 to push, moving the material cylinder 100 laterally between the rear wall of the front support block 30 and the front wall of the rear support plate 12, and then into the corresponding material cylinder placement position between the side self-lubricating layer 171 and the inner self-lubricating layer 112, and on the top surface of the rotating plate 20. At this time, the corresponding proximity switch 3 senses the moving block, indicating that it has moved into place. At this time, the moving block of the rodless cylinder 15 has moved into place.
[0034] Then, by running the corresponding limit rotation servo motor 31, the guide wheel 33 is brought close to the front wall of the corresponding material cylinder 100 for further limitation. At this time, the sensing end of the first proximity switch 4 senses the corresponding end of the swing arm 32, indicating that it is in the limit position. Then, the yarn feeding host 10 of the yarn winding machine runs, and the yarn will enter the material cylinder 100. By running the rotation servo motor 21, the material cylinder 100 is rotated, so that the yarn entering can be wound along the material cylinder 100 for feeding, and the feeding effect is good.
[0035] After completion, the rotary servo motor 21 stops running, and the limit rotary servo motor 31 runs, causing the swing arm 32 to return to the elongated groove 34 and rest against the limit block 35. At this time, the second proximity switch 5 senses the corresponding end of the swing arm 32, indicating that it has moved into place. At the same time, the moving block of the rodless cylinder 15 moves, so that it is sensed by the outer proximity switch 3, indicating that it has returned to place.
[0036] At this time, the pusher of the corresponding pusher cylinder 14 pushes the pusher block 141 forward, pushing the corresponding material cylinder 100 forward out of the material cylinder placement position. There are no obstructing parts above the front of the material cylinder placement position, so the operating space is large. At this time, it is only necessary to manually pull the material cylinder 100 away, which realizes automatic unloading, which is very convenient.
[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
