Detailed Implementation

[0016] The present invention will be further described in detail below through specific embodiments:

[0017] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a yarn cutting mechanism, including a cylinder 1 and a cutter 2. The output shaft of the cylinder 1 is connected to a connecting seat 31 assembly 3 for connecting to the connecting end of the cutter 2. The connecting seat 31 assembly 3 includes a connecting seat 31 and a locking structure 32. The connecting seat 31 is fixedly connected to the output shaft of the cylinder 1, and its bottom has a mounting groove 33 extending from one side wall to the other side wall for the connecting end of the cutter 2 to be embedded and limited. The locking structure 32 is connected to the connecting seat 31 and is fitted at the insertion opening of the mounting groove 33.

[0018] This yarn cutting mechanism is detachably connected to the output shaft of the cylinder 1 and the connecting end of the cutter 2 via the connecting seat 31 assembly 3, so that the cutter 2 can be disassembled when it is maintained or replaced. Specifically, when disassembling, the locking structure 32 is released from the locking of the connecting end of the cutter 2 at the insertion opening of the mounting groove 33, and then the connecting end of the cutter 2 is withdrawn from its insertion opening in the mounting groove 33, so as to facilitate the disassembly of the cutter 2 and facilitate the maintenance and replacement of the cutter 2.

[0019] In this embodiment, the cutter 2 is an existing structure, specifically the cutter 2 in CN222975393U. The connecting end of the cutter 2 is "L" shaped, and the mounting groove 33 is also "L" shaped to adapt to the connecting end of the cutter 2, so that the connecting end of the cutter 2 is stably limited within the mounting groove 33. After being locked by the locking structure 32, the cutter 2 is stably connected to the connecting seat 31.

[0020] To facilitate disassembly, the connecting end of the cutter 2 can be easily removed from the mounting slot 33, such as... Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, the yarn cutting mechanism includes an elastic retraction structure 34 arranged on the inner wall of the mounting groove 33 facing the insertion opening. The elastic retraction structure 34 includes a retraction ejector block 341 and an elastic element. The retraction ejector block 341 is slidably disposed in the mounting groove 33 and arranged facing the insertion opening. The elastic element is connected between the retraction ejector block 341 and the inner wall of the mounting groove 33.

[0021] In this embodiment, the cutter 2 is installed as follows: its connecting end slides from the insertion port into the mounting groove 33 and contacts the retracting ejector block 341, and then continues to slide, the elastic element contracts until it reaches the installation position, and then the locking structure 32 is adjusted to abut against the connecting end of the cutter 2 at the insertion port, so that the connecting end of the cutter 2 is stably limited in the mounting groove 33, thereby completing the installation of the cutter 2.

[0022] When the cutter 2 is disassembled, the locking structure 32 is released from locking the connecting end of the cutter 2, the elastic element extends to allow the ejector block 341 to slide in the mounting groove 33 toward the insertion port, the connecting end of the cutter 2 is ejected from the insertion port, and then the connecting end of the cutter 2 is held to completely withdraw from the mounting groove 33, which helps to speed up the disassembly efficiency of the cutter 2.

[0023] The elastic element can be a spring.

[0024] To prevent the connecting end of the cutter 2 from moving too far during the process of being pushed out by the retracting block 341, and to avoid the connecting end of the cutter 2 completely detaching from the mounting slot 33 and falling off; Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, the yarn cutting mechanism wherein the connecting seat 31 is rotatably provided with an anti-drop structure 35 located at the insertion port to cooperate with the cutter 2.

[0025] When it is necessary to disassemble the cutter 2, rotate the anti-drop structure 35 to position it on the exit path of the connecting end of the cutter 2. Then, adjust the locking structure 32 to release the restriction on the connecting end of the cutter 2. The retracting cutter ejector block 341 pushes the connecting end of the cutter 2 out of the mounting slot 33 until the connecting end of the cutter 2 abuts against the anti-drop structure 35, preventing the connecting end of the cutter 2 from exiting too far. Then, the operator holds the connecting end of the cutter 2 and rotates the anti-drop structure 35 to release the restriction, allowing the connecting end of the cutter 2 to slide completely out of the mounting slot 33, thus completing the disassembly. During installation, it is necessary to first ensure that the anti-drop structure 35 does not cause any restriction.

[0026] Based on the above solution:

[0027] The anti-fall structure 35 includes a connecting part 351 and a blocking part 352. The connecting part 351 is fixedly connected to the outer wall of the connecting seat 31. The blocking part 352 is rotatably connected to the connecting part 351, and part of it can be rotated to the side of the insertion port and located on the exit path of the connecting end of the cutter 2.

[0028] In use: the retractable part 352 is rotated around the connecting part 351. After the retractable part 352 is rotated to the exit path of the connecting end of the cutter 2, the retractable part 352 restricts the connecting end of the cutter 2 from completely sliding out of the mounting groove 33. The retractable part 352 is rotated to disengage it from the exit path of the connecting end of the cutter 2, so as to avoid the retractable part 352 from obstructing the installation of the cutter 2.

[0029] In this embodiment, the connecting part 351 specifically includes a connecting cylinder connected to the connecting seat 31 and a limiting ring arranged on the end of the connecting cylinder away from the connecting seat 31; the blocking part 352 includes an "L"-shaped blocking rod, one end of which is fixedly connected to a rotating limiting ball that freely passes through the central hole of the limiting ring and is movably arranged inside the connecting cylinder. The rotating limiting ball cooperates with the limiting ring to keep the blocking rod and the connecting cylinder stably rotated and connected; in use, the blocking rod is rotated to control whether it is placed on the exit path of the connecting end of the cutter 2.

[0030] To better understand the locking structure 32, such as Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, in the yarn cutting mechanism, the connecting seat 31 has an assembly hole on one side wall that communicates with the mounting groove 33, and the locking structure 32 partially slides through the assembly hole and extends into the mounting groove 33 to abut against the end of the cutter 2 that is located at the insertion port.

[0031] In this embodiment, the mounting hole provides installation and movement space for the locking structure 32, so that the locking structure 32 can lock or unlock the connecting end of the cutter 2 embedded in the mounting groove 33.

[0032] The locking structure 32 includes a locking block 321 and a gripping part 322. The locking block 321 slides through the assembly hole and extends into the mounting groove 33 to cooperate with the connecting end of the cutter 2. The gripping part 322 is placed outside the connecting seat 31 and is connected to the locking block 321.

[0033] The grip 322 allows the operator to hold and slide the locking block 321 to control the locking block 321 to lock or unlock the connecting end of the cutter 2 embedded in the mounting groove 33.

[0034] Specifically, the gripping part 322 includes a limiting block connected to the locking block 321 and a gripping ring connected to the limiting block. The locking block 321 is moved by taking the gripping ring. When the limiting block abuts against the outer wall of the connecting seat 31, the locking block 321 and the connecting end of the cutter 2 in the mounting groove 33 cooperate well to lock.

[0035] This yarn cutting mechanism not only optimizes the connection structure of the cutter 2, such as... Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the yarn cutting mechanism further includes a fixed blade seat 4 located below the cutter 2, and the top of the fixed blade seat 4 has a VV-shaped limiting guide groove 41 for the yarn to pass through.

[0036] In this embodiment, the fixed blade holder 4 has a square frame structure, and VV-shaped limiting guide grooves 41 are distributed on the two opposing side walls of the square frame structure. The VV-shaped limiting guide grooves 41 can guide yarns of different thicknesses to pass through. The cylinder 1 drives the cutter 2 to move downward to move into the inside of the fixed blade holder 4 to cut the yarn.

[0037] Furthermore, the yarn cutting mechanism also includes a base 5, on the top surface of which a mounting sleeve 6 is fixedly connected. The bottom of the fixed blade holder 4 is detachably connected within the mounting sleeve 6. The fixed blade holder 4 is specifically secured within the mounting sleeve 6 by multiple screws, facilitating its installation and replacement.

[0038] The mounting sleeve 6 has a positioning block 7 on its outer wall, the cylinder 1 is connected to a support frame 8, the support frame 8 is detachably connected to the base 5 and the support frame 8 has a positioning groove for the positioning block 7 to be embedded in for positioning.

[0039] Here, the support frame 8 serves as the mounting skeleton for the cylinder 1, and the support frame 8 and the base 5 can be fixedly connected by multiple screws; the positioning block 7 cooperates with the positioning groove to improve the installation accuracy of the support frame 8, thereby improving the installation accuracy of the cylinder 1 and the cutter 2, so that the cutter 2 can cooperate well with the yarn.

[0040] When maintaining or replacing cutter 2, this yarn cutting mechanism is as follows:

[0041] Rotate the retraction part 352 to rotate it onto the exit path of the connecting end of the cutter 2;

[0042] The rear gripping part 322 is used to move the locking block 321 out of the mounting groove 33 and disengage it from the connecting end of the cutter 2.

[0043] The connecting end of the cutter 2 slides out of the mounting groove 33 under the action of the retracting ejector block 341 until it abuts against the retracting part 352;

[0044] Hold the connecting end of the cutter 2 and rotate the retraction part 352 to remove it from the exit path of the connecting end of the cutter 2, so that the connecting end of the cutter 2 can be completely removed from the mounting groove 33.

[0045] When the cutter 2 is installed, the yarn cutting mechanism is as follows:

[0046] Ensure that the retraction part 352 is not on the exit path of the connecting end of the cutter 2;

[0047] Hold the connecting end of the cutter 2 and slide it from the insertion port into the mounting groove 33 until it reaches the mounting position and abuts against the retracting ejector block 341;

[0048] Next, hold the gripping part 322 and slide the locking block 321 into the mounting groove 33 to abut against the connecting end of the cutter 2 to complete the installation of the cutter 2.

[0049] When this yarn cutting mechanism is in operation:

[0050] Start cylinder 1, which drives cutter 2 to press down. Together with fixed cutter holder 4, cutter 2 cuts the yarn.

[0051] like Figure 2 As shown, according to another embodiment of the present invention, the warping machine has a yarn cutting mechanism in any of the above embodiments and other existing structures, so that the warping machine has the structural advantages of the above yarn cutting mechanism.
