The carrier assembly 8 can clamp or release the thread 9. The air blowing pipe 6 is located above the thread 9. The lifting seat 2, the clamping mechanism 5, and the cutting mechanism 3 can move closer to or away from the thread 9 in the vertical direction under the drive of the first linear movement mechanism. The air blowing pipe 6 can blow the cotton thread 91 in the thread 9 towards the clamping mechanism 5. The clamping end of the clamping mechanism 5 can clamp or release the cotton thread 91. The cutting mechanism 3 can cut the cotton thread 91. The collecting mechanism 7 can collect the cut cotton thread 91. In use, the carrier assembly 8 clamps the thread 9 and aligns the end of the thread 91 to be cut with the cutting mechanism 3. At this time, the thread 9 is above the cutting mechanism 3. Then, driven by the first linear movement mechanism, the clamping mechanism 5 and the cutting mechanism 3 approach the thread 9 from bottom to top. Then, the air pipe 6 blows air towards the thread 91. Since the thread 91 is lighter and softer than the core of the thread 9, while the core of the thread 9 has a certain rigidity, the thread 91 is easily blown by the airflow, while the core is not easily blown away. The airflow blown downward by the air pipe 6 separates the thread 91 from the core of the thread 9. At this time, the thread is blown by the air pipe 9 towards the clamping mechanism 5, which clamps and fixes the thread 91. Then, the cutting mechanism 3 cuts the thread 91. The cut thread 91 is collected by the collecting mechanism 7, thus realizing the cutting of excess thread. Compared with manual cutting, it has a higher degree of automation. It has the advantage of high automation.

The second cylinder 35 is fixed to the lifting seat 2. The second cylinder 35 is connected to the slide plate 31, and the third cylinder 36 is fixed to the slide plate 31. The cylinder rod of the third cylinder 36 is connected to the cutter holder 34. The slide plate 31, cutting seat 32, cutter head 33, cutter holder 34, and third cylinder 36 can move closer to or away from the carrier assembly 8 under the drive of the second cylinder 35. The cutter holder 34 and cutter head 33 can move closer to or away from the cutting seat 32 under the drive of the third cylinder 36. The bottom surface of the cutter head 33 and the top surface of the cutting seat 32 are both flat. The bottom surface of the cutter head 33 can be in close contact with the top surface of the cutting seat 32, and the blade can cut the cotton thread 91. When the cotton thread 91 extends between the cutting seat 32 and the cutter head 33, the third cylinder 36 drives the cutter head 33 to move closer to the cutting seat 32, so that the blade can contact the cotton thread 91 to cut the cotton thread 91.
[0032] Optionally in this embodiment, the cutter head 33 is detachably fixed to the cutter holder 34 by bolts. This allows the cutter head 33 to be easily replaced when it wears out.
[0033] Optionally in this embodiment, the clamping mechanism 5 includes a gripper cylinder 51 and a gripper 52. A fourth slide rail is vertically arranged on the side wall of the lifting seat 2.

[0034] Optionally in this embodiment, a tube seat is fixed on the extension seat, and a connection hole is vertically opened on the tube seat.

A breathable mesh bag is provided between the collecting pipe 71 and the vacuum pipe 72. The collecting pipe 71 has a collecting port on the side facing the clamping mechanism 5. The cut cotton thread 91 can enter the collecting pipe 71 through the collecting port and be captured by the mesh bag. In this embodiment, the collecting pipe 71 is fixed to the connecting plate 53, so the collecting mechanism 7 can move together with the clamping mechanism 5, which facilitates the collection of the cut cotton thread 91. In this embodiment, the mesh bag is detachable, so when the mesh bag is full of cotton thread, it can be removed to clean the cotton thread 91 inside.
[0036] Optionally in this embodiment, the carrier assembly 8 includes a platform 81, a buckle 82, a fifth cylinder 83, a sixth cylinder 84, a first clamping block 85, and a second clamping block 86. The carrier assembly 8 and the cutting mechanism 3 are arranged adjacent to each other. The buckle 82 is fixed to the top surface of the platform 81, and the top of the buckle 82 has a groove for inserting the wire 9. The first clamping block 85 is fixed to the cylinder rod of the fifth cylinder 83 by a first fixing seat 87, and the second clamping block 86 is fixed to the cylinder rod of the sixth cylinder 84 by a second fixing seat 88. 6 is located directly above the first clamping block 85. The first clamping block 85 and the second clamping block 86 face each other. V-shaped notches are opened on the opposite surfaces of the first clamping block 85 and the second clamping block 86. The wire 9 can be inserted between the first clamping block 85 and the second clamping block 86. The first clamping block 85 can move closer to the second clamping block 86 in the vertical direction under the drive of the fifth cylinder 83. The second clamping block 86 can move closer to the first clamping block 85 in the vertical direction under the drive of the sixth cylinder 84.

[0037] Optionally in this embodiment, the second clamping block 86 has an air blowing hole 89 inclined on the side facing the cutting mechanism 3. An air pipe connector is provided on the side wall of the second clamping block 86, connecting the air blowing hole 89 and an air source. The air blowing hole 89 can blow air onto the cotton thread 91. By simultaneously or alternately blowing air onto the cotton thread 91 through the vertically arranged air pipe 6 and the inclined air blowing hole 89, the separation efficiency of the cotton thread 91 and the yarn 9 can be improved. In this embodiment, a solenoid valve is provided between the air blowing hole 89 and the air source. When it is necessary to cut the cotton thread 91, the air blowing hole 89 stops blowing air to avoid interference. In this embodiment, the airflow speed of the air blowing pipe 6 and air blowing hole 89 towards the cotton thread 91 can be finely adjusted according to different specifications of thread. The specific airflow speed can be determined through experiments. The user can first fix the thread 9 on the carrier assembly 8, and then gradually increase the blowing speed of the air source until the cotton thread 91 is blown away and separates from the core of the thread 9. The preferred airflow speed is one that can just blow the cotton thread 91 without blowing away the core of the thread 9. Then, the same type of thread can be processed in batches according to the airflow speed obtained from the experiment. In this embodiment, the air source has a flow rate adjustment function.
[0038] Optionally in this embodiment, the angle between the axis of the air hole 89 and the ground is forty-five degrees.
[0039] Movement Process: First, the thread 9 is inserted into the groove of the buckle 82, at which point the thread 9 is positioned between the first clamping block 85 and the second clamping block 86. Then, the fifth cylinder 83 and the sixth cylinder 84 drive the first clamping block 85 and the second clamping block 86 to move closer together. The first clamping block 85 and the second clamping block 86 clamp and fix the thread 9 through the V-shaped notch. At this time, the air blowing pipe 6 is located directly above the thread 9. Then, the lifting seat 2, the clamping mechanism 5, and the cutting mechanism 3 move upward and closer to the thread 9 under the drive of the first cylinder 4. Then, the sliding plate 31, the cutting seat 32, the blade head 33, the blade holder 34, and the third cylinder 36 move closer to the carrier assembly 8 under the drive of the second cylinder 35, so that the blade head 33 and the cutting seat 32 are located directly below the cotton thread 91. Then, the air blowing pipe 6 and the air blowing hole 89 blow air towards the cotton thread 91, causing the cotton thread 91 and the core of the thread 9 to separate. Then, the air blowing hole 89 stops blowing air. At this time, air is blown from top to bottom through the air pipe 6 towards the cotton thread 91, causing the cotton thread 91 to extend between the cutting seat 32 and the blade 33 located below. Then, the clamping mechanism 5 and the collecting mechanism 7 move upward and approach the cotton thread 91 under the drive of the fourth cylinder 55. The gripper cylinder 51 drives the grippers 52 to approach each other and clamp the end of the cotton thread 91. Then, the fourth cylinder 55 drives the clamping mechanism 5 to move downward to put the cotton thread 91 in a taut state. Then, the blade 33 approaches the cutting seat 32 under the drive of the second cylinder 35, and the blade cuts off the root of the cotton thread 91. Then, the clamping mechanism 5 releases the cut cotton thread 91. At the same time as the clamping mechanism 5 releases the cotton thread 91, the vacuum generator connected to the collecting mechanism 7 is activated to generate negative pressure at the collecting port. The negative pressure sucks the cut cotton thread 91 into the collecting port and is captured by the mesh bag, thereby realizing the automated cutting of the cotton thread 91.
[0040] The thread pretreatment and cutting mechanism in this embodiment has the advantage of a high degree of automation.
