[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown:

[0025] An automatic cutting machine with adjustable cutting length includes a cutting table 101 and an automatic cutting machine body 102 disposed on the cutting table 101.

[0026] In this implementation plan: to solve the technical problems existing in the prior art, such as the "when cutting multiple sets of fabrics of different lengths from a set of fabrics, since the automatic cutting machine is in a fixed position, the length of the fabric is usually measured manually with a ruler multiple times. The automatic cutting machine is difficult to automatically adjust the cutting length under manual intervention, which makes the production process discontinuous, leading to production interruption and reducing overall production efficiency" in combination with the actual use, this problem is obviously a real and difficult problem to solve.

[0027] Furthermore:

[0028] like Figures 1-3 As shown:

[0029] Based on the above: The cutting table 101 is equipped with an L-shaped bracket 103, and the main body 102 of the automatic cutting machine is fixedly installed on the surface of the L-shaped bracket 103;

[0030] A drive mechanism 2 is installed on the cutting table 101 to move the L-shaped bracket 103;

[0031] The drive mechanism 2 includes a frame 203 fixed to one side of the cutting table 101 and a first guide rod 204 fixed inside the frame 203 and arranged symmetrically. One end of the L-shaped bracket 103 can slide on the surface of the first guide rod 204 through the through hole. A rack 205 is fixed to one side of the frame 203.

[0032] A geared motor 201 is fixedly mounted on one side of the L-shaped bracket 103 via a mounting base. A drive shaft is fixed to the output end of the geared motor 201, and a gear 202 that meshes with the rack 205 is fixed to one end of the drive shaft.

[0033] A connecting plate 206 is fixed on the surface of the L-shaped bracket 103 near the position of the geared motor 201. The connecting plate 206 is rotatably connected by a bearing and a drive shaft. An electric push rod 207 is fixedly installed at the bottom of the mounting base. An abutment rod 208 is fixed at the output end of the electric push rod 207. A through hole adapted to the abutment rod 208 is opened on the connecting plate 206. The abutment rod 208 can pass through the through hole opened in the connecting plate 206 and abut against the surface of the frame 203.

[0034] A positioning plate 104 is fixed to one end of the upper surface of the cutting table 101, and a laser rangefinder 105 corresponding to the positioning plate 104 is fixedly installed on the surface of the L-shaped bracket 103.

[0035] The initial end of the laser rangefinder 105 is flush with the cutting surface of the automatic cutting machine body 102.

[0036] In this implementation plan: When using the automatic cutting machine with adjustable cutting length, first place the garment fabric on the cutting table 101, align one end of the fabric with one side of the positioning plate 104, and at the same time lay the fabric flat.

[0037] When cutting fabric to different lengths, the geared motor 201 is started, driving the gear 202 to rotate via the drive shaft. The gear 202 meshes with the rack 205, which is fixed to one side of the frame 203. When the gear 202 moves on the rack 205, it causes the L-shaped bracket 103 to slide on the two positioning plates 104. The L-shaped bracket 103 synchronously moves the automatic cutting machine body 102, and also synchronously moves the laser rangefinder 105. At this time, the laser rangefinder 105 emits a laser beam, which shines on the positioning plate 104. The positioning plate 104 reflects the laser beam... The light is received by the laser rangefinder 105. The laser rangefinder 105 determines the distance between the cutting surface of the automatic cutting machine body 102 and the positioning plate 104 by calculating the time difference or phase difference between the emitted laser and the received reflected laser. When this distance reaches the specified cutting distance, the built-in electronic circuit of the laser rangefinder 105 converts the measurement result into an electrical signal, which sends a stop signal to the PLC controller. After receiving the signal, the PLC controller immediately sends a command to the geared motor 201 to stop it from running. At this time, the distance between the cutting surface of the automatic cutting machine body 102 and the positioning plate 104 corresponds to the cutting length. Then the automatic cutting machine body 102 is started to perform the cutting operation.

[0038] During this process, by activating the electric push rod 207, the contact rod 208 is moved downward, so that one end of the contact rod 208 comes into contact with the surface of the frame 203. The friction between the contact rod 208 and the frame 203 improves the stability of the L-shaped bracket 103 and improves the cutting effect.

[0039] Next, the geared motor 201 can be started, which will drive the automatic cutting machine body 102, L-shaped bracket 103 and laser rangefinder 105 to move synchronously. At this time, the distance projected by the laser rangefinder 105 onto the positioning plate 104 minus the length of the first cut can be the distance of the second cut. Repeating this operation, a set of fabric can be cut into multiple pieces of different lengths. This structure eliminates the need for manual measurement of different lengths of fabric before cutting by the automatic cutting machine body 102, reducing measurement and adjustment time. The automatic cutting machine can automatically adjust the cutting length without manual intervention, making the production process more continuous, reducing production interruptions and improving overall production efficiency.

[0040] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is installed on the cutting table 101. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those skilled in the art, so it will not be described in detail here.

[0041] Furthermore;

[0042] In an optional embodiment, a fixing mechanism 3 for securing the garment fabric is installed on the cutting table 101;

[0043] The fixing mechanism 3 includes side plates that are symmetrically arranged and fixed on the cutting table 101. A second guide rod 301 that is symmetrically arranged is fixed between the two sets of side plates. Multiple sets of sliding seats 302 are provided on the side of the cutting table 101 near the two sets of second guide rods 301. The sliding seats 302 can slide on the surface of the two sets of second guide rods 301 through the circular holes. The sliding seats 302 are threadedly connected to the extrusion bolts 303 that can abut against the side of the cutting table 101 through the threaded holes.

[0044] A lower pressure plate 304 is provided on the sliding seat 302. A rectangular cavity is provided on the sliding seat 302, and a symmetrically arranged limiting rod 305 is provided in the rectangular cavity. The limiting rod 305 and the sliding seat 302 are fixedly connected. The lower pressure plate 304 can slide up and down on the surface of the two sets of limiting rods 305 through the opening of the moving hole. A spring 306 is wound around the surface of the limiting rod 305. The two ends of the spring 306 are fixedly connected to the sliding seat 302 and the lower pressure plate 304 respectively.

[0045] A pull rod 307 is fixed on the surface of the lower pressure plate 304 near the sliding seat 302. A fixing plate 308 is fixed to the top of the pull rod 307. The fixing plate 308 is located above the sliding seat 302. A sliding hole adapted to the pull rod 307 is opened on the top of the sliding seat 302. The pull rod 307 and the sliding seat 302 are slidably connected through this sliding hole. A strip groove is opened on the top of the sliding seat 302, and a top rod 309 is provided in the strip groove. One end of the top rod 309 is hinged to the sliding seat 302 through a hinge shaft. A scale line is provided on the side of the cutting table 101 away from the reduction motor 201.

[0046] In this embodiment: the spring 306 is in a compressed state. The rebound of the spring 306 can drive the lower pressure plate 304 to slide on the limiting rod 305, so that the lower pressure plate 304 generates downward pressure, thereby making the lower pressure plate 304 closely fit the surface of the cutting table 101. Thus, the fabric placed on the surface of the cutting table 101 can be pressed and fixed by the lower pressure plate 304, which improves the stability of the fabric on the cutting table 101 and avoids wrinkles when the automatic cutting machine body 102 cuts the fabric, thus affecting the cutting effect.

[0047] By pulling the fixed plate 308, the lower pressure plate 304 is moved upward, and the top rod 309 is flipped so that the top rod 309 contacts the edge of the strip groove opened in the sliding seat 302. At this time, the top rod 309 is in an inclined state, and this inclination direction is opposite to the direction of the opening of the strip groove. At the same time, the fixed plate 308 is released to generate a certain downward pressure on one end of the top rod 309. The top rod 309 can temporarily resist the fixed plate 308, so that the lower pressure plate 304 can have a certain distance from the cutting table 101, which makes it easier to place the fabric on the surface of the cutting table 101.

[0048] The cutting table 101 has a scale line on the side away from the reduction motor 201. The specific position of multiple sliding seats 302 can be adjusted by observing the scale line. The specific position means that the cutting point of each group can be known by observing the scale line. The sliding seat 302 slides on the second guide rod 301, thereby driving the lower pressure plate 304 to move, so that the adjacent lower pressure plates 304 are located on both sides of the cutting point. Then, the movement of the sliding seat 302 is stopped, and the side of the cutting table 101 is pressed by rotating the pressing bolt 303, so as to fix the sliding seat 302 and the second guide rod 301. The two sets of lower pressure plates 304 press down and fix the two ends of the cutting point, thereby improving the cutting accuracy of the automatic cutting machine body 102 on the fabric and improving the practicality and flexibility of this structure.

[0049] The working principle and usage process of this utility model: When using this adjustable-length automatic cutting machine, first place the garment fabric on the cutting table 101, aligning one end of the fabric with one side of the positioning plate 104, and simultaneously flatten the fabric. When cutting the fabric to different lengths, the starting of the reduction motor 201 drives the gear 202 to rotate via the drive shaft. The gear 202 and rack 205 are meshed and connected, and the rack 205 is fixed to one side of the frame 203. Thus, when the gear 202 meshes and moves on the rack 205, it drives the L-shaped... The support 103 slides on two sets of positioning plates 104. The L-shaped support 103 drives the automatic cutting machine body 102 to move synchronously, and the L-shaped support 103 also drives the laser rangefinder 105 to move synchronously. At this time, the laser rangefinder 105 emits a laser beam, which shines on the positioning plates 104. The positioning plates 104 reflect the laser beam, and the reflected light is received by the laser rangefinder 105. The laser rangefinder 105 determines the distance between the cutting surface of the automatic cutting machine body 102 and the positioning plates 104 by calculating the time difference or phase difference between the emitted laser beam and the received reflected laser beam. When the specified cutting distance is reached, the built-in electronic circuit of the laser rangefinder 105 converts the measurement result into an electrical signal, which sends a stop signal to the PLC controller. Upon receiving the signal, the PLC controller immediately sends a command to the geared motor 201 to stop its operation. At this point, the distance between the cutting surface of the automatic cutting machine body 102 and the positioning plate 104 corresponds to the cutting length. Subsequently, the automatic cutting machine body 102 is started to perform the cutting operation. Then, the geared motor 201 can be started again, thereby driving the automatic cutting machine body 102, the L-shaped bracket 103, and the laser rangefinder. The laser rangefinder 105 moves synchronously. At this time, the distance projected by the laser rangefinder 105 onto the positioning plate 104 minus the length of the first cut is the distance for the second cut. Repeating this operation allows for multiple cuts of different lengths from a single piece of fabric. This structure eliminates the need for manual measurement of different fabric lengths before the automatic cutting machine body 102 performs the cutting operation, reducing measurement and adjustment time. The automatic cutting machine can automatically adjust the cutting length without manual intervention, making the production process more seamless, reducing production interruptions, and improving overall production efficiency.
