DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] like Figure 3 to Figure 11 As shown, this embodiment discloses a clamping and positioning device for a yarn tube, including a clamping mechanism 3, wherein the clamping mechanism 3 is mounted on a frame 1, and the clamping mechanism 3 is provided with a slide plate 31, relatively distributed abutment blocks 34 and abutment plates 37, wherein the number of the abutment blocks 34 and the abutment plates 37 is two and they are distributed at intervals, and the slide plate 31 is slidably mounted on the frame 1.

[0029] The slide plate 31 is provided with a mounting frame 32, and the frame 1 is provided with a slide bar 311. The slide plate 31 can move along the slide bar 311 toward or away from the stop plate 37. Furthermore, the frame 1 is provided with a driving member 312. The driving member 312 can be a cylinder. The output end of the driving member 312 is connected to the slide plate 31 to drive the slide plate 31 to move back and forth.

[0030] The two abutment blocks 34 are relatively arranged on the mounting frame 32, and then the abutment blocks 34 are driven by the slide plate 31 to move close to the abutment plate 37. Furthermore, a driving member 5 35 is installed on the mounting frame 32. The driving member 5 35 can be a cylinder. The output end of the moving member 5 35 is connected to the abutment block 34. The two abutment blocks 34 are distributed at both ends of the remaining yarn tube 6. The remaining yarn tube 6 is a tube body with yarn 62 wound around the outer periphery of the yarn tube 61. The yarn 62 extends outward from both ends of the yarn tube 61. When the yarn 62 wound around the outer periphery of the remaining yarn tube 6 is cut, the remaining yarn tube 6 is the yarn tube 61.

[0031] The abutment block 34 is a laterally arranged truncated cone, and the abutment block 34 can extend from the two end ports of the remaining yarn tube 6 and abut the remaining yarn tube 6, and then the abutment block 34 can move relatively and abut against the two ends of the remaining yarn tube 6. Specifically, the abutment block 34 abuts against the two ends of the yarn tube 61, and the abutment block 34 can clamp and move the remaining yarn tube 6 to drive the remaining yarn tube 6 to move.

[0032] The abutment plate 37 is used to abut the remaining yarn tube 6 driven by the abutment block 34. Specifically, a waist-shaped hole for installing the mounting rod 36 is opened on the frame 1. The two abutment plates 37 correspond to the mounting rod 36 one by one and are installed on the mounting rod 36. The abutment plate 37 is an arc-shaped abutment plate. The inner contour of the abutment plate 37 is adapted to the outer contour of the yarn tube 61, so that the two abutment plates 37 can abut on the two end sides of the yarn tube 61 respectively.

[0033] A driving member 43 is installed on the slide plate 31. The driving member 433 can be a cylinder. The output end of the driving member 433 is connected to the mounting frame 32. The driving member 433 is used to drive the abutment block 34 to move upward close to the abutment plate 37.

[0034] Specifically, the abutment block 34 clamps the remaining yarn tube 6 and moves close to the abutment plate 37 through the slide plate 31, and then drives the abutment block 34 to move upward through the driving member 33, so that the remaining yarn tube 6 clamped by the abutment block 34 can abut upward to the limit position of the abutment plate 37, so as to realize the positioning of the cutting point of the remaining yarn tube 6, and avoid the situation that the yarn 62 is not cut into place or the yarn tube 61 is cut due to the dimensional tolerance of the yarn tube 61 itself, so that the yarn 62 cutting operation of the remaining yarn tube 6 is more efficient and will not cut the yarn tube 61.

[0035] Furthermore, the clamping and positioning design of the present embodiment can also meet the needs of positioning and cutting of other pipes, and is not limited to the use of cutting the remaining yarn tube 6 in the present embodiment.

[0036] The mounting rod 36 is provided with a waist-shaped hole which is vertically arranged, and the support plate 37 is installed on the mounting rod 36 through the waist-shaped hole. The height of the support plate 37 can be adjusted through the waist-shaped hole which is vertically arranged, so as to adjust the cutting point of the remaining yarn tube 6 up and down to meet the needs of cutting the remaining yarn tube 6 of different thicknesses.

[0037] refer to Figures 1 to 13 As shown, this embodiment also discloses a bobbin yarn cutting machine, including a gear frame 1 and a conveying mechanism 2, a clamping mechanism 3, a cutting mechanism 4, and a yarn suction mechanism 5 installed on the frame 1, a suction fan 11 is installed inside the frame 1, and the suction fan 11 provides the yarn suction mechanism 5 with the negative pressure required for sucking the fallen yarn, and an electric control box 12 is installed on the frame 1.

[0038] refer to Figure 1 , Figure 3 to Figure 6 As shown, the conveying mechanism 2 is used to convey the remaining yarn tube 6, and the remaining yarn tube 6 includes a yarn tube 61 and a yarn 62 wound around the outer circumference of the yarn tube 61, and the yarn 62 extends outward from both ends of the yarn tube 61.

[0039] The clamping mechanism 3 is located at the conveying end of the conveying mechanism 2. The conveying mechanism 2 is provided with a bottom plate 21 which extends downwardly and obliquely toward the clamping mechanism 3. Side plates 22 are provided on both sides of the bottom plate 21. The two side plates 22 are spaced apart and mutually form a channel for the remaining yarn tubes 6 to roll through in sequence. A plurality of remaining yarn tubes 6 are provided between the two side plates 22. The remaining yarn tubes 6 can be rolled and conveyed in sequence toward the clamping mechanism 3 along the length direction of the bottom plate 21.

[0040] A shift rod 25 abutting against the remaining yarn tube 6 is provided at the end of the bottom plate 21, and a second driving member 26 is installed on the frame 1. The second driving member 26 can be a cylinder, and the output end of the second driving member 26 is connected to the shift rod 25 so that the shift rod 25 can move up and down. When the shift rod 25 moves upward, the shift rod 25 abuts against the remaining yarn tube 6 to limit the further displacement of the remaining yarn tube 6. When the shift rod 25 moves downward, the remaining yarn tube 6 is avoided so that the remaining yarn tube 6 can move further.

[0041] The side plate 22 is provided with an abutment plate 23. Specifically, a driving member 24 is installed on the side plate 22. The driving member 24 can be a cylinder. The output end of the driving member 24 is connected to the abutment plate 23, so that the abutment plate 23 can move and abut the remaining yarn tube 6 between the two side plates 22. When the gear lever 25 moves downward to allow the remaining yarn tube 6 to move further, the abutment plate 23 moves between the two side plates 22 to abut the subsequent remaining yarn tube 6 to prevent the remaining yarn tube 6 from continuing to be transported.

[0042] The conveying mechanism 2 also includes a limit plate 28 which is distributed relative to the bottom plate 21 up and down. The limit plate 28 cooperates with the bottom plate 21 to limit the yarn 62 from being wound around the excessively thick residual yarn tube 6 and passing through. The limit plate 28 is adjustably installed by bolts. When the limit plate 28 is adjusted upward, the relatively thick residual yarn tube 6 can pass through.

[0043] A notch 221 is provided between the side plate 22 and the stop rod 25, and the abutment block 34 is located outside the notch 221. Two abutment blocks 34 are distributed at both ends of the remaining yarn tube 6 abutting against the stop rod 25. The abutment block 34 can move inward through the notch 221 and abut against and fix the remaining yarn tube 6.

[0044] refer to Figure 2 , Fig.13 As shown, the cutting mechanism 4 is provided with a cutting knife 43 and a heat flow gun 44 for cutting the remaining yarn tube 6, and the cutting mechanism 4 is installed with a protection rod 13 for protecting the cutting knife 43 and the heat flow gun 44.

[0045] The cutting mechanism 4 is also provided with a shift plate 42 which can reciprocate along the length direction of the remaining yarn tube 6. The shift plate 42 is slidably set on a bracket 41 of the cutting mechanism 4. The bracket 41 is provided with a transversely set slide bar 2 411. The length direction of the slide bar 2 411 is parallel to the length of the remaining yarn tube 6. The shift plate 42 reciprocates along the slide bar 2 411.

[0046] The cutting mechanism 4 is provided with a driving member 6 421, which may be a motor. The output end of the driving member 6 421 is connected with a transmission belt 422, which is fixed to the shift plate 42. The driving member 6 421 drives the shift plate 42 to move back and forth through the transmission belt 422.

[0047] The cutting blade 43 and the heat flow gun 44 are respectively mounted on the moving plate 42 via corresponding adjusting rods 45 , and the relative heights of the cutting blade 43 and the heat flow gun 44 can be adjusted up and down by rotating the adjusting rods 45 .

[0048] During the reciprocating movement of the shift plate 42, the yarn 62 is cut by the cooperation of the cutting knife 43 and the heat flow gun 44. Specifically, the cutting knife 43 is used to quickly cut most of the yarn 62 on the remaining yarn tube 6, and then the heat flow gun 44 is used to melt the remaining small amount of yarn 62 to achieve rapid cutting of the yarn 62. In addition, this cutting method allows the cutting knife 43 to leave a certain distance from the yarn tube 61 when cutting the yarn 62, and the cutting of the remaining yarn tube 6 is positioned by the abutment plate 37 to ensure that the cutting knife 43 can cut the yarn 62 on the remaining yarn tube 6 without damage.

[0049] In this embodiment, the distribution of the cutting knife 43 and the heat flow gun 44 is that the cutting knife 43, the heat flow gun 44, and the cutting knife 43 are distributed in sequence, so that the moving plate 42 can cut two remaining yarn tubes 6 during one reciprocating motion, thereby improving the yarn cutting efficiency of the remaining yarn tube 6.

[0050] The frame 1 is provided with a discharge plate 51 below the abutment plate 37 , and the discharge plate 51 is tilted outwardly. After the yarn 62 on the remaining yarn tube 6 is cut, the abutment block 34 moves in the opposite direction, so that the yarn tube 61 can fall to the discharge plate 51 , and the yarn tube 61 is recovered by guiding through the discharge plate 51 .

[0051] The yarn suction mechanism 5 includes a yarn suction hole 511 located below the abutment plate 37, and the yarn suction hole 511 is opened on the unloading plate 51. A negative pressure tube 52 that can move upward close to the yarn suction hole 511 is arranged below the unloading plate 51. The negative pressure tube 52 generates negative pressure through the suction fan 11. A driving member 53 is installed on the frame 1. The driving member 53 can be a cylinder. The output end of the driving member 53 is connected to the negative pressure tube 52 to drive the negative pressure tube 52 to move close to or away from the yarn suction hole 511. When it is necessary to suck the cut and fallen yarn 62 through the yarn suction hole 511, the negative pressure tube 52 is moved close to the yarn suction hole 511 to increase the suction force near the yarn suction hole 511, so that the yarn suction hole 511 can collect and process the fallen yarn 62 uniformly through the negative pressure.

[0052] further, Figure 3 to Figure 5 As shown, the side plate 22 is mounted on the bottom plate 21 through a waist-shaped hole, and the two mounting rods 36 can move toward each other along the length direction of the waist-shaped hole. A waist-shaped hole for mounting the mounting plate 27 is provided on the frame 1, and the shift rod 25 is mounted on the mounting plate 27, and the two shift rods 25 can move toward each other along the length direction of the waist-shaped hole.

[0053] Furthermore, the two side plates 22, the two abutment plates 37 mounted on the mounting rods 36, and the two stop rods 25 mounted on the mounting plate 27 can all be relatively spaced to meet the use of the remaining yarn tubes 6 of different lengths in this embodiment.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
