DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] Reference Figure 1 and Figure 2 The utility model discloses a strap cutting mechanism of a strap machine, including a base 100, an ultrasonic generating device 300 and a first linear driving mechanism 500 both connected to the base 100, the base 100 is connected to the main body of the strap machine through a horizontal sliding mechanism 200; the ultrasonic generating device 300 is connected to an ultrasonic cutter head 400; the output end of the first linear driving mechanism 500 is connected to a mechanical cutter head 600, a space between the ultrasonic cutter head 400 and the mechanical cutter head 600 is provided for the strap to pass through, and the first linear driving mechanism 500 drives the mechanical cutter head 600 to press the strap against the ultrasonic cutter head 400 to cut the strap.

[0025] By setting the horizontal sliding mechanism 200, the base 100 can be easily moved on the main body of the strap machine to adjust the position of the strap cutting mechanism. When the strap cutting mechanism is in different positions, strap segments of different lengths can be cut from the strap. The strap to be cut passes between the ultrasonic cutter head 400 and the mechanical cutter head 600, and then the first linear drive mechanism 500 drives the mechanical cutter head 600 to move. The mechanical cutter head 600 pushes the strap against the ultrasonic cutter head 400, and the ultrasonic generator 300 drives the ultrasonic cutter head 400. Under the joint action of the mechanical cutter head 600 and the ultrasonic cutter head 400, the strap can be cut, and the incision is flush.

[0026] The ultrasonic generating device 300, the ultrasonic cutter head 400, the first linear drive mechanism 500 and the mechanical cutter head 600 are all arranged on the base 100. When the base 100 is moved to adjust the length of the cut strap, the ultrasonic cutter head 400 and the mechanical cutter head 600 move synchronously with the base 100. When the first linear drive mechanism 500 drives the mechanical cutter head 600 to move toward the ultrasonic cutter head 400, the mechanical cutter head 600 rests on the same position on the ultrasonic cutter head 400 each time. The mechanical cutter head 600 and the ultrasonic cutter head 400 have a high degree of fit, which ensures that the tape cutting mechanism can cut the strap evenly while also ensuring a long service life and high reliability.

[0027] If the position of the mechanical cutter head 600 against the ultrasonic cutter head 400 is random each time, the fit between the mechanical cutter head 600 and the ultrasonic cutter head 400 is reduced, and the incision quality and service life of the shoulder strap cannot be guaranteed.

[0028] In some of the embodiments, the belt cutting mechanism of the shoulder belt machine also includes a second linear drive mechanism 700, the second linear drive mechanism 700 is connected to the main body of the shoulder belt machine, the output end of the second linear drive mechanism 700 is connected to the base 100, and the second linear drive mechanism 700 drives the base 100 to move on the main body of the shoulder belt machine.

[0029] It is conceivable that the second linear drive mechanism 700 can be a cylinder, the cylinder body of the second cylinder is hinged to the main body of the harness machine, and the piston rod of the second cylinder is hinged to the base 100 .

[0030] In some of the embodiments, the horizontal sliding mechanism 200 includes a first slide rail and a first slider that cooperate with each other. The first slide rail is horizontally arranged. One of the first slide rail and the first slider is connected to the main body of the shoulder strap machine, and the other is connected to the base 100. The first slider can easily slide on the first slide rail, so that the base 100 can be easily moved on the main body of the shoulder strap machine.

[0031] There are two horizontal sliding mechanisms 200, and two first slide rails are arranged side by side on the main body of the shoulder strap machine. The base 100 is supported on the two first slide rails through the two first sliders, so that the base 100 can be supported in a relatively balanced manner.

[0032] In some of the embodiments, the cutting edge of the ultrasonic cutter head 400 faces upward, the mechanical cutter head 600 is disposed above the ultrasonic cutter head 400, the cutting edge of the mechanical cutter head 600 faces the cutting edge of the ultrasonic cutter head 400, the first linear drive mechanism 500 drives the mechanical cutter head 600 to move downward, the cutting edge of the mechanical cutter head 600 presses the shoulder strap down and against the cutting edge of the ultrasonic cutter head 400, and the cutting edge of the mechanical cutter head 600 and the cutting edge of the ultrasonic cutter head 400 clamp the shoulder strap.

[0033] In some of the embodiments, the cutting edge of the mechanical cutting head 600 is wedge-shaped, and the cutting edge of the ultrasonic cutting head 400 is flat. The wedge-shaped cutting edge of the mechanical cutting head 600 is sharp, and the cutting edge of the ultrasonic cutting head 400 is wider, ensuring that the cutting edge of the mechanical cutting head 600 can press the shoulder strap against the cutting edge of the ultrasonic cutting head 400.

[0034] In some of the embodiments, a support frame 110 is provided on the base 100, and the first linear drive mechanism 500 is connected to the base 100 through the support frame 110. The output end of the first linear drive mechanism 500 faces downward and is connected to the mechanical cutter head 600. The support frame 110 supports the first linear drive mechanism 500 on the base 100, so that the first linear drive mechanism 500 and the mechanical cutter head 600 are above the ultrasonic cutter head 400.

[0035] In some of the embodiments, the support frame 110 is connected to the mechanical cutter head 600 via a vertical sliding mechanism 800 , and the vertical sliding mechanism 800 serves to guide the moving direction of the mechanical cutter head 600 .

[0036] The vertical sliding mechanism 800 includes a second slide rail and a second slider that cooperate with each other. The second slide rail is vertically arranged. One of the second slide rail and the second slider is connected to the support frame 110, and the other is connected to the mechanical cutter head 600. The second slider can easily slide on the second slide rail, so that the mechanical cutter head 600 can be lifted and lowered under the guidance of the second slide rail.

[0037] The first linear drive mechanism 500 is a first cylinder, the cylinder body of the first cylinder is connected to the support frame 110, the piston rod of the first cylinder is set downward, and the mechanical tool head 600 is connected to the tool holder, and the tool holder is detachably connected to the piston rod of the first cylinder.
