[Example]

Please refer to FIG. 1 to FIG. 3. The present invention provides a movable suction pipe structure for a thread cutting device of a sewing machine. The sewing machine 100 includes a work platform 1, a machine arm 2, a sewing tool set 3 and all thread device 4. The arm 2 is installed on the work platform 1, and the arm 2 is disposed corresponding to the work platform 1. The sewing tool set 3 is installed on the arm 2 and extends to the surface of the work platform 1. The sewing machine 100 can perform sewing operations through the work platform 1, the arm 2 and the sewing tool set 3.

The thread cutting device 4 includes a driver 41 and a thread cutter 42. The driver 41 is installed on the arm 2, and the driver 41 is located above the work platform 1. The structure of the driver 41 is not limited, and may be a motor. , Solenoid valves or pneumatic cylinders. The thread cutter 42 is mounted on a driver 41, which can drive the thread cutter 42 to move up and down for cutting the wire 6.

During use of the sewing machine 100, the work platform 1 may be provided with two fabrics (not shown), and the sewing tool set 3 may sewn a wire 6 to the two fabrics to perform sewing operations on the two fabrics. When the sewing tool set 3 is sewing, the part of the wire 6 that is not sewn to the two fabrics will protrude from the outside of the work platform 1 and be located below the thread cutting knife 42. The actuator 41 can drive the cutting knife 42 to rise and fall, and the cutting knife 42 can cut the wire 6 during the descending process. Since the above-mentioned working platform 1, the arm 2, the sewing tool set 3, and the thread cutting device 4 are prior art, and the construction does not limit its structure, it will not be described in detail.

This creation is mainly provided with a movable suction pipe structure 5 on the sewing machine 100, which can be used to attract the cut portion of the wire 6. The movable suction pipe structure 5 includes a driving device 51 and a suction pipe 52. The driving device 51 is installed on the arm 2. The structure of the driving device 51 is not limited, and may be a motor, a solenoid valve, or a pneumatic cylinder. And other driving devices. In this embodiment, the driving device 51 is a pneumatic cylinder. The pneumatic cylinder has a cylinder body 511 and a driving shaft 512. The driving shaft 512 can be extended or contracted relative to the cylinder body 511 in order to drive the suction. The bobbin 52 moves up and down.

The suction pipe 52 is mounted on a driving device 51, and the driving device 51 can drive the suction pipe 52 to move up and down. In this embodiment, the suction pipe 52 is mounted on the driving shaft 512 of the driving device 51 so as to drive the suction pipe 52 to rise and fall. The suction pipe 52 is a hollow pipe body. The suction pipe 52 has a suction port 521 and a discharge port 522. The suction port 521 and the discharge port 522 may be located at opposite ends of the suction pipe 52. The suction line The exhaust port 522 of the tube 52 may be connected to an air suction device (not shown) for attracting air flow to absorb the cut-off portion of the wire 6. Since the air suction device is the prior art, and the creation does not limit the Structure, so I will not repeat them.

In this embodiment, a guide seat 53 is provided at one end of the cylinder body 51. The guide seat 53 has a guide groove 531. The suction pipe 52 is disposed on a lifting seat 54 through which the suction pipe 52 passes. The lifting base 54 is mounted on the driving shaft 512. The lifting base 54 is provided with a guide 55. The guide 55 is slidably fitted into the guide groove 531 to guide the suction tube 52 to move up and down.

The driving device 51 can switch between a first state and a second state to lift the suction pipe 52. In the first state, the suction port 521 of the suction pipe 52 is located at a first position A (as shown in FIG. 3), and the suction port 521 of the suction pipe 52 is located at a high point, that is, the suction line The suction port 521 of the tube 52 is far from the wire 6. In this second state, the suction port 521 of the suction pipe 52 is located at a second position B (as shown in FIG. 4), and the second position B is located below the first position A. The suction port 521 is located at a low point, and the second position B is closer to the wire 6 than the first position A, so that the suction port 521 of the suction pipe 52 is close to the wire 6, which can shorten the suction port 521 of the suction pipe 52 and the The distance between the cut portions of the wire 6 allows the suction opening 521 of the suction pipe 52 to be as close as possible to the cut portion of the wire 6, so it can be solved that the fixed suction pipe cannot be close to the cut portion of the wire and will have an absorption effect. The best question.

Furthermore, the cutting knife 42 is installed on the actuator 41, and the suction pipe 52 is installed on the driving device 51. The cutting knife 42 and the suction pipe 52 are respectively connected to different power sources, and the cutting knife 42 and the suction pipe 52 are respectively connected. Can act independently. The cutting knife 42 and the suction pipe 52 do not need to move synchronously, so that the wire 6 can be reliably absorbed. For example, the suction pipe 52 can be driven down first, and then the cutting knife 42 is driven down; when the wire 6 is cut, the cutting knife 42 is driven up and reset first, and then the suction pipe 52 is driven up and reset, so that the entire wire 6 is cut off. In the process, the suction pipe 52 is located near the cut portion of the wire 6, so that the wire 6 can be reliably absorbed.
