Description

Technical Field

[0001] The utility model relates to the technical field of rapier looms, in particular to a trimming mechanism which is convenient for adjusting the position of a cutting blade. Background Art

[0002] In the process of weaving cloth using a rapier loom, it is often necessary to use a trimming mechanism to trim the woven cloth, and most of the existing trimming mechanisms are fixed to the rapier loom frame by multiple sets of bolts, which results in a relatively fixed position of the cutting blade of the trimming mechanism. When adjustment is required, multiple sets of tools are required to remove the trimming mechanism before adjustment can be made, and this process is cumbersome. Utility Model Content

[0003] In order to solve the above technical deficiencies, the utility model provides a trimming mechanism which is convenient for adjusting the position of a cutting blade and can conveniently change the cutting position of the cutting blade.

[0004] The utility model discloses a trimming mechanism for adjusting the position of a cutting blade, comprising a rapier loom frame, a servo motor, a tube body, a cutting blade, a spring, a sliding rod, a connecting piece, a fixed disk, a controller and a limiting piece. The rapier loom frame is provided with a servo motor, the servo motor is electrically connected to the controller, an external thread is provided at the end of a rotating shaft of the servo motor, an internal thread is provided at the inner side of the tube body, the tube body is screwed on the rotating shaft of the servo motor, a cutting blade is coaxially provided at the end of the tube body away from the servo motor, a fixing disk is coaxially provided at the middle part of the rotating shaft of the servo motor, a plurality of No. 1 plug holes are evenly provided on the fixing disk, a No. 2 plug hole is provided on the cutting blade at a position corresponding to the No. 1 plug hole on the fixing disk, one end of the sliding rod passes through the No. 1 plug hole, and a limiting piece is provided at the end of the sliding rod after the other end of the sliding rod passes through the No. 2 plug hole, each sliding rod is connected by a connecting piece, a spring is sleeved on the sliding rod between the connecting piece and the cutting blade, the spring is in a compressed state, one end of the spring presses against the cutting blade, the other end of the spring presses against the connecting piece, and the limiting piece presses against the cutting blade.

[0005] When the above technical solution needs to adjust the position of the cutting blade, the connecting piece is moved toward the cutting blade to further compress the spring and disengage the slide rod from the No. 1 socket. The servo motor is then controlled to rotate forward or reverse through the controller, thereby adjusting the position between the tube body and the servo motor shaft so that the cutting blade is close to or away from the servo motor. After adjusting the position of the cutting blade, the connecting piece is released. It should be noted here that the rotation angle of the servo motor should be such that the slide rod can be inserted into the No. 1 socket after the connecting piece is released.

[0006] Preferably, the number of the No. 1 jack, the No. 2 jack, the sliding rod, the spring and the limiter are all four, so that the structure is relatively stable and the adjustment accuracy is relatively high, and the structure is also relatively simple.

[0007] The utility model provides a cutting mechanism which is convenient for adjusting the position of a cutting blade, and has the beneficial effect of being able to conveniently adjust the cutting position of the cutting blade. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0011] Embodiment 1:

[0012] like Figure 1 , 2 As shown, the utility model discloses a trimming mechanism for adjusting the position of a cutting blade, comprising a rapier loom frame 1, a servo motor 2, a tube body 9, a cutting blade 10, a spring 7, a slide bar 5, a connector 6, a fixing plate 4, a controller, and a limiter 8. The rapier loom frame 1 is provided with a servo motor 2, the servo motor 2 is electrically connected to the controller, an external thread is provided at the end of a servo motor shaft 3, an internal thread is provided on the inner side of a tube body 9, the tube body 9 is screwed on the shaft 3 of the servo motor 2, the end of the tube body 9 away from the servo motor 2 is coaxially provided with a cutting blade 10, and the servo motor shaft 3 is electrically connected to the controller, and an external thread is provided at the end of the servo motor shaft 3. A fixed disk 4 is coaxially arranged in the middle part, and four No. 1 sockets are evenly arranged on the fixed disk 4. A No. 2 socket is arranged on the cutting blade 10 at a position corresponding to the No. 1 socket on the fixed disk 4. One end of the slide rod 5 passes through the No. 1 socket, and the other end of the slide rod 5 passes through the No. 2 socket and a limiting member 8 is arranged at the end. The slide rods 5 are connected by a connecting member 6. A spring 7 is sleeved on the slide rod 5 between the connecting member 6 and the cutting blade 10. The spring 7 is in a compressed state. One end of the spring 7 presses against the cutting blade 10, and the other end of the spring 7 presses against the connecting member 6, and the limiting member 8 presses against the cutting blade 10.

[0013] When the above technical solution needs to adjust the position of the cutting blade 10, the connecting piece 6 is moved toward the cutting blade 10 to further compress the spring 7, and the slide bar 5 is disengaged from the No. 1 socket. Then the servo motor 2 is controlled by the controller to rotate forward or reverse, thereby adjusting the position between the tube body 9 and the servo motor shaft 3, so that the cutting blade 10 is close to or away from the servo motor 2. After the position of the cutting blade 10 is adjusted, the connecting piece 6 is released. It should be noted here that the rotation angle of the servo motor 2 should be such that the slide bar 5 can be inserted into the No. 1 socket after the connecting piece 6 is released.
