Specific embodiments

[0023] Please refer to the attached Figure 1 to Figure 6 As shown, the present utility model is a tube feeding mechanism of a full-automatic winding machine, which is used to convey a plurality of yarn tubes 10, and is composed of a frame 1, a bottom plate 2, a guide rail 3, a slider 4, a tube connecting seat 5, a lead screw 6, a conveying motor 7, a hopper 8, a cylinder I 9, etc.

[0024] Among them, the bottom plate 2 is installed on the frame 1. In this embodiment, a bearing seat 11 is installed on the frame 1, and one end of the bottom plate 2 is pivotally connected to the frame 1 through the bearing seat 11, so that the bottom plate 2 can rotate relative to the frame 1. A limit block 21 is provided at the other end of the bottom plate 2, and the limit block 21 is installed on the frame 1 and can abut against the side surface of the bottom plate 2 to prevent the bottom plate 2 from deflecting when rotating.

[0025] Furthermore, a compression spring seat 12 is provided on the frame 1, a compression spring 13 is provided in the compression spring seat 12, and the compression spring 13 abuts against the bottom of the bottom plate 2 to support the bottom plate 2 and cooperate with the limit block 21 to keep the bottom plate 2 in a horizontal state.

[0026] The guide rail 3 is fixed on the bottom plate 2; the slider 4 is matched with the guide rail 3 and slides along the guide rail 3.

[0027] The tube connecting seat 5 is installed on the slider 4 and is driven by the slider 4. A plurality of yarn tube positioning grooves 51 are provided on the tube connecting seat 5, and one yarn tube 10 can be received in each yarn tube positioning groove 51. In this embodiment, 4 yarn tube positioning grooves 51 are provided, so that 4 yarn tubes 10 can be conveyed simultaneously, and the yarn tube positioning grooves 51 can position the yarn tubes 10 to prevent the yarn tubes 10 from rolling.

[0028] The lead screw 6 is pivotally connected to the bottom plate 2 through a lead screw seat 61; the lead screw 6 is screwed with the slider 4, so that the lead screw 6 can drive the slider 4 to reciprocate along the guide rail 3. The conveying motor 7 is installed on the bottom plate 2 and is on the same side as the bearing seat 11. The conveying motor 7 can drive the lead screw 6 to rotate. Specifically, the conveying motor 7 and the lead screw 6 are driven by a synchronous pulley 71 and a synchronous belt 72.

[0029] The hopper 8 is installed on the frame 1. It is located at one end of the guide rail 3 and can accommodate a number of yarn tubes 10 inside. The hopper 8 is vertically arranged, and clamping arms 81 are provided on both sides thereof. The yarn tubes 10 are clamped between the clamping arms 81 to prevent the yarn tubes 10 from falling and to arrange the yarn tubes 10 in a single stacked arrangement up and down. A yarn tube induction probe 82 is installed on the hopper 8, which can detect whether there is a yarn tube 10 in the hopper 8, so as to replenish the yarn tubes 10 in time and ensure that each yarn tube positioning groove 51 of the tube connecting seat 5 can receive a yarn tube 10.

[0030] The cylinder I 9 is installed at the bottom on one side of the hopper 8 and includes a mandrel 91 which can be inserted into the bottommost yarn tube 10 to prevent the yarn tube 10 from falling.

[0031] A cylinder II 15 is installed on the frame 1; the cylinder II 15 is connected to one end of the bottom plate 2, and the cylinder II 15 and the bearing seat 11 are located at different ends of the bottom plate 2. The cylinder II 15 can drive the bottom plate 2 to rotate around the bearing seat 11 to tilt the tube connecting seat 5.

[0032] The working principle of the tube feeding mechanism of the full-automatic winding machine of the present utility model is as follows:

[0033] 1), The yarn tube induction probe 82 detects whether there is a yarn tube 10 in the hopper 8. If there is no yarn tube 10, the vibrating disk (not shown) is started to automatically add yarn tubes 10 into the hopper 8 for use. At this time, the mandrel 91 of the cylinder I 9 is inserted into the bottommost yarn tube 10 (as shown in Figure 4 ), to prevent the yarn tube 10 from falling.

[0034] 2), When the winding machine needs a new yarn tube 10, the conveying motor 7 is started, which drives the lead screw 6 to rotate. The rotation of the lead screw 6 drives the slider 4 to move along the guide rail 3, and the movement of the slider 4 drives the tube connecting seat 5 to extend. At this time, the mandrel 91 of the cylinder I 9 retracts, and the bottommost yarn tube 10 falls onto the tube connecting seat 5, but is still restricted by the hopper 8.

[0035] 3), The conveying motor 7 continuously drives the tube connecting seat 5. When the yarn tube positioning groove 51 of the tube connecting seat 5 passes by the bottommost yarn tube 10, this yarn tube 10 is loaded into the yarn tube positioning groove 51 until one yarn tube 10 is loaded into each of the 4 yarn tube positioning grooves 51, as shown in Figure 5 .

[0036] 4), After the winding machine grabs the 4 yarn tubes 10 on the tube connecting seat 5, the cylinder II 15 retracts, causing the bottom plate 2 to rotate downward by an angle, so that the yarn tubes 10 on the tube connecting seat 5 are separated from the tube connecting seat 5, and the yarn tubes 10 will not be caught when the tube connecting seat 5 retracts. At the same time, the conveying motor 7 rotates in the reverse direction to reset the tube connecting seat 5, as shown in Figure 1As shown. After the adapter seat 5 is reset, the cylinder II 15 is also reset, and the bottom plate 2 is kept in a horizontal state by the compression spring 13.

[0037] The above specific implementation manners are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
