Only conventional horizontal cutting can be realized, and special-shaped cutting cannot be realized. When special-shaped cutting is required, the length of the cutting wire needs to be changed, and the cutting wire must maintain a certain tension. Utility Model Content

[0021] Example 1

[0022] A constant tension control mechanism for a foam special-shaped cutting machine, the specific structure after installation is as follows:

[0023] It comprises a foam placing platform 1, an X-axis slide track 2 is respectively arranged on both sides of the foam placing platform, a cutting wire first connector assembly 3 and a cutting wire second connector assembly 4 are respectively arranged on the X-axis slide track, the cutting wire first connector assembly is connected to the X-axis slide track on the corresponding side through a first driving mechanism, and the cutting wire second connector assembly is connected to the X-axis slide track on the corresponding side through a second driving mechanism;

[0024] The first driving mechanism and the second driving mechanism respectively drive the first cutting wire connector assembly and the second cutting wire connector assembly to move in the X-axis and Y-axis directions;

[0025] A cutting wire (not shown) is connected between the first cutting wire connector assembly and the second cutting wire connector assembly;

[0026] Wherein, the first connector assembly of the cutting wire includes a first mounting plate 100, on which a cutting wire reel 101 is arranged, on which the first end of the cutting wire is wound, and the cutting wire reel is connected to a rotating drive member 102, which is a pneumatic rotary drive motor. Since the extension and contraction amount of the cutting wire is not much (generally not more than 10 cm) during special-shaped cutting, the shaft of the drive member 102 is often in a non-rotating (i.e., blocked) state, so the constant torque motor cannot be applied because of the problem of burning out due to blocking. The present application adopts pneumatic rotary drive to ensure the normal operation of the equipment. A first guide member is also arranged on the first mounting plate, and the first guide member includes a first guide wheel 103 arranged below the cutting wire reel, and also includes a first guide column 104 arranged on the side of the first guide wheel, and a first guide hole 105 is arranged in the first guide column, and the cutting wire bypasses the first guide wheel 103 and passes through the second guide hole 105 to be connected to the second connector assembly of the cutting wire;

[0027] The second connector assembly of the cutting wire includes a second mounting plate 106, on which a second guide member and an elastic connector are arranged, the second end of the cutting wire passes through the second guide member and is connected to the elastic connector, the second guide member includes a second guide column 107 arranged on the second mounting plate, a second guide wheel 108 is arranged on the side of the second guide column, and a second guide hole (not shown) is arranged in the second guide column, the elastic connector includes a bending plate 110 arranged on the second mounting plate, and an elastic hook 111 is connected to the bending plate.

[0028] In the present application, the first driving mechanism and the second driving mechanism have the same structure.

[0029] The first driving mechanism includes a Y-axis sliding track 200, on which a first X-axis sliding drive motor 201 is arranged, and an X-axis conveying belt 202 is arranged on the X-axis sliding track, and the output shaft end of the first X-axis sliding drive motor is connected to the X-axis conveying belt through a first synchronous wheel 203; a Y-axis sliding drive motor 204 is arranged near the bottom end of the Y-axis sliding track, and a second synchronous wheel 205 is arranged on the output end of the Y-axis sliding drive motor, and a second synchronous wheel mounting plate 206 is arranged near the top end of the Y-axis sliding track, and a third synchronous wheel 207 is arranged on the third synchronous wheel mounting plate, and a Y-axis conveying belt 208 is transmission-connected between the second synchronous wheel and the third synchronous wheel; the first mounting plate is fixedly connected to the Y-axis conveying belt.

[0030] A clamping plate 209 is fixed on the rear end surface of the first mounting plate, and the clamping plate is clamped on the Y-axis conveying belt. The first X-axis sliding drive motor is arranged on the bottom end of the Y-axis sliding track, and the second X-axis sliding drive motor 210 is arranged on the top end of the Y-axis sliding track.

The second X-axis sliding drive motor is connected to the X-axis auxiliary conveying belt through a fourth synchronous wheel.

[0031] In the present application, when cutting special shapes, the first connector assembly of the cutting wire and the second connector assembly of the cutting wire need to be at different heights, so the cutting wire needs to be lengthened or shortened, thereby rotating the cutting wire reel to release or reel in the wire to achieve a balance of the tension of the cutting wire.
