DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0024] Refer to Figures 1 - 4 As shown, the grooved drum structure of a winding machine includes a grooved drum 1. A paper tube (not shown) is rotatably provided at the top of the grooved drum 1. A transmission shaft is provided in the grooved drum 1. Fixed brackets 2 are sleeved at both ends of the transmission shaft. A driving motor 3 is provided at one end of the grooved drum 1. It further includes:

[0025] Adjustable end caps 4 are provided at both ends of the grooved drum 1 and are rotatably connected to the paper tube. By sleeving end caps at both ends of the grooved drum 1, the starting transmission point position of the bobbin yarn is moved forward from the original 1 / 3 of the paper tube to the head of the small end of the paper tube, so that a 1-mm gap is maintained between the paper tube and the grooved drum 1, and the original transmission point is discarded, so that the starting winding of the yarn achieves a frictionless effect. The height of the adjustable end cap 4 can be adjusted as needed, so that the distance between the grooved drum 1 and the paper tube changes;

[0026] A driving assembly 5 is provided on one side of the adjustable end cap 4 and is used to control the height of the adjustable end cap 4.

[0027] In one embodiment, the adjustable end cap 4 includes a fixed part 41 sleeved on the grooved drum 1. A plurality of movable parts 42 are circumferentially and arrayedly distributed on the fixed part 41. The movable parts 42 are slidably connected to the fixed part 41. A sleeve 43 sleeved on the transmission shaft is provided on one side of the fixed part 41. The driving assembly 5 is provided on the sleeve 43;

[0028] During installation, let the sleeve 43 on the fixed part 41 be sleeved along the transmission shaft, and then the fixed part 41 is clamped on the grooved drum 1. At the beginning, the movable parts 42 and the fixed part 41 form a circle. When adjustment is needed, the movable parts 42 can be pushed by the driving assembly 5, and the movable parts 42 can extend outward along the fixed part 41, so as to adjust the distance between the paper tube and the grooved drum 1.

[0029] In one embodiment, a slot is further formed on the surface of the fixing portion 41. A fixing bolt 40 is inserted into the slot, and the fixing portion 41 is fixedly connected to the drum 1 through the fixing bolt 40.

[0030] After the adjustable end cap 4 is sleeved on the drum 1, the adjustable end cap 4 can be fixed by tightening the fixing bolt 40 inward.

[0031] In one embodiment, a plurality of movable slots are formed on the fixing portion 41. The movable portion 42 is located in the movable slots. A sliding slot is formed on the inner wall of the movable slot. Limiting sliders 422 that slide in the sliding slot are arranged on both sides of the movable portion 42, ensuring that the movable portion 42 can only slide up and down along the fixing portion 41.

[0032] In one embodiment, the driving assembly 5 includes a hydraulic rod 51 fixed to the sleeve 43. The movable end of the hydraulic rod 51 is connected to a movable ring 52. The movable ring 52 is sleeved on the sleeve 43. The movable ring 52 can slide on the sleeve 43 under the push of the hydraulic rod 51. An adjusting rod 53 connected to the movable portion 42 is arranged on the movable ring 52. When the movable ring 52 moves, the adjusting rod 53 will be pushed. The adjusting rod 53 will then push the movable portion 42 to extend outwards. At this time, the paper tube at its top will contact the movable portion 42, thereby changing the distance between the paper tube and the drum 1.

[0033] In one embodiment, a first fixing block 421 is arranged on the surface of the movable portion 42. One end of the adjusting rod 53 is rotatably connected to the first fixing block 421. A second fixing block 521 is arranged on the movable ring 52. The end of the adjusting rod 53 away from the first fixing block 421 is rotatably connected to the second fixing block 521.

[0034] When the movable ring 52 pushes the adjusting rod 53, the adjusting rod 53 will deflect appropriately, thereby changing the horizontal movement of the movable ring 52 into the vertical movement of the movable portion 42.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
