[0035] In one embodiment of the present invention, as Figures 1 to 2As shown in the figure, a laser cold knife dual-mode material cutting device 100 is provided, which includes a fixed seat 101, a motor 102, a cold knife seat 103, a cold knife, a cylinder 104 and a laser tube 105. The motor 102 and the cylinder 104 are both installed and connected to the fixed seat 101. Among them, the cold knife is not shown in the figure, and both it and the laser tube 105 itself belong to the prior art. That is, this application does not lie in improving the cold knife and the laser tube 105, but only by selecting the cold knife and the laser tube 105 of the prior art. Both of these two cutting tools can cut fabrics and can be respectively applicable to the cutting of different fabrics.

[0036] Further, as Figures 1 to 2 shown, the cold knife seat 103 is connected to the main shaft of the motor 102 and can move up and down under the drive of the motor 102. The cold knife is installed on the cold knife seat 103.

[0037] Even further, as Figures 1 to 2 shown, the laser tube 105 is connected to the piston rod of the cylinder 104 and can move up and down under the drive of the cylinder 104, and the laser tube 105 is arranged adjacent to the cold knife.

[0038] The laser cold knife dual-mode material cutting device 100 provided by the embodiment of the present utility model can be applied to a sewing machine. When working, the cold knife seat 103 is controlled by the motor 102 to move up and down, and then the cold knife is controlled to move up and down, so as to cut the fabric. And because it is also provided with a cylinder 104 and a laser tube 105 driven by the cylinder 104, by controlling the up and down movement of the laser tube 105 through the cylinder 104, the fabric can be cut by the laser tube 105. In this way, according to actual needs, the cold knife or the laser tube 105 is respectively used to cut different fabrics, with flexible use, rich modes and wide application range.

[0039] In an embodiment of the present utility model, as Figures 1 to 2 shown, the laser cold knife dual-mode material cutting device 100 further includes a cylinder mounting plate 106. The cylinder mounting plate 106 is fixedly connected to one side of the fixed seat 101, and the side surface of the cylinder 104 is fixedly connected to the side surface of the cylinder mounting plate 106. Specifically, the additionally provided cylinder mounting plate 106 can be used to support the installation of the cylinder 104, and according to the connection between the cylinder mounting plate 106 and the fixed seat 101, the installation position of the cylinder 104 can be set at the required position, and then the installation position of the cylinder 104 can be arranged more flexibly to adapt to the use of the sewing machine. The connection between the cylinder mounting plate 106 and the fixed seat 101, and the connection between the cylinder 104 and the cylinder mounting plate 106 can both be locked by fasteners such as screws and bolts.

[0040] In one embodiment of the present utility model, as Figures 1 to 2 shown, the laser cold knife dual-mode cutting device 100 further includes a laser tube fixing member 107. One side of the laser tube fixing member 107 is fixedly connected to the bottom of the piston rod of the air cylinder 104. The other side of the laser tube fixing member 107 is provided for the laser tube 105 to pass through and be fixed, and the laser tube 105 is arranged side by side with the air cylinder 104. Specifically, by adding the laser tube fixing member 107, the laser tube 105 and the piston rod of the air cylinder 104 can be connected at a horizontal or nearly horizontal position, so that the laser tube 105 and the air cylinder 104 can be arranged side by side. This can reduce the vertical volume of the entire device, and at the same time ensure that the air cylinder 104 can effectively drive the laser tube 105.

[0041] In one embodiment of the present utility model, as Figures 1 to 2 shown, the laser cold knife dual-mode cutting device 100 further includes a guide rail 108, a slider 109 and a sliding plate 110.

Among them, the first connecting rod 111 is arranged horizontally, and the second connecting rod 112 is in an "S" shape. In this way, the rotation of the main shaft of the motor 102 can drive the first connecting rod 111 to swing, and then the swing of the first connecting rod 111 drives the second connecting rod 112. The lower end of the second connecting rod 112 can move up and down, so as to drive the sliding plate 110 to move up and down guided by the guide rail 108. The control method is ingenious and has strong practicability.

[0043] In one embodiment of the present utility model, as Figures 1 to 2As shown in the figure, a plurality of upper fixing holes 1101 are arranged at intervals on the sliding plate 110 and are used to cooperate with the lower end of the second connecting rod 112 for a fastener to pass through and connect. Specifically, different upper fixing holes 1101 at different positions on the sliding plate 110 can be selected to cooperate and lock with the lower end of the second connecting rod 112, so that second connecting rods 112 of different lengths or shapes can be used, and then different cold knives can be adapted for operation.

[0044] In an embodiment of the present invention, as Figures 1 to 2 shown, the cold knife seat 103 includes an upper knife seat block 1031 and a lower knife seat block 1032 connected to the upper knife seat block 1031.

Specifically, the position of the upper knife seat block 1031 is horizontally moved so that the horizontal strip hole 10311 thereon is aligned with the upper fixing holes 1101 at different positions, and the connection between the two is realized by a fastener passing through. In this way, the installation position of the upper knife seat block 1031 can be adjusted horizontally on the left and right, realizing the selection of different positions of the cold knife, and being flexibly applicable.

[0045] In an embodiment of the present invention, as Figures 1 to 2 shown, a longitudinal strip hole 10312 is provided at the bottom of the upper knife seat block 1031, and a lower fixing hole 10321 capable of cooperating with the longitudinal strip hole 10312 for a fastener to pass through and connect is provided at the top of the lower knife seat block 1032. Specifically, the position of the lower knife seat block 1032 is moved horizontally in the longitudinal direction so that the lower fixing hole 10321 provided thereon is aligned with the longitudinal strip hole 10312 provided at the bottom of the upper knife seat block 1031, and the connection between the two is realized by a fastener passing through. In this way, the installation position of the lower knife seat block 1032 can be adjusted horizontally on the left and right in the longitudinal direction, realizing the selection of different positions of the cold knife, and being flexibly applicable.

[0046] In an embodiment of the present invention, as Figures 1 to 2 shown, a plurality of cold knife fixing holes 10322 are arranged at intervals on the side surface of the lower knife seat block 1032 and are used for a fastener to pass through and connect and fix the cold knife. The setting of the cold knife fixing holes 10322 can flexibly install the position of the cold knife on the lower knife seat block 1032, be flexibly used, and facilitate the installation and disassembly of the cold knife.

[0047] The embodiment of the present invention also provides a fabric sewing machine, as Figure 3As shown in the figure, it includes the above-mentioned laser cold knife dual-mode material cutting device 100. On the fabric sewing machine of the present invention, since the above-mentioned laser cold knife dual-mode material cutting device 100 is used, when it works, the motor 102 of the laser cold knife dual-mode material cutting device 100 controls the up and down movement of the cold knife seat 103, and then controls the up and down movement of the cold knife, so as to cut the fabric. And because it is also provided with a cylinder 104 and a laser tube 105 driven by the cylinder 104, the up and down movement of the laser tube 105 is controlled by the cylinder 104, and then the fabric can be cut by the laser tube 105.
