The device is characterized by: a telescopic cylinder mounted on the upper frame of the support frame, the telescopic end of which passes through the upper frame; a telescopic frame mounted on the telescopic end of the cylinder; two triangular plates hinged to the inner side of the telescopic frame's end; a fixing plate between the two triangular plates; limit rails on both the left and right sides of the support frame; the fixing plate embedded within the limit rails; a cutting blade for cutting the color steel sheet on the fixing plate; a placement platform for placing the color steel sheet and cooperating with the cutting blade on the inner bottom surface of the support frame; and a conveying mechanism at the rear of the support frame for transporting the cut color steel sheet to the next step. This utility model effectively cuts color steel sheets and transports the cut sheets, saving significant manpower and resources and improving work efficiency.

[0003] However, this device has some shortcomings. When in use, it is not convenient to adjust the limit, which can cause the color-coated plate to shift position during movement. At the same time, when the color-coated plate moves to contact the saw wheel, the excessive clamping force can cause the saw wheel teeth to collide and be damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for the production of color-coated steel sheets, which solves the problems that the device is not easy to adjust and limit, causing the color-coated steel sheet to shift position during movement. At the same time, when the color-coated steel sheet moves to contact the saw wheel, the excessive clamping force will cause the saw wheel teeth to collide and be damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for color-coated steel sheet production, comprising a workbench, a saw wheel mounted on the workbench, a support plate slidably connected inside the workbench, a bracket slidably connected to the outside of the workbench, a guide bar fixedly connected inside the bracket, the guide bar slidably connected to the workbench, a support plate fixedly connected to the upper end of the workbench, an adjustment mechanism mounted on the support plate, a limit mechanism mounted on the bracket, the adjustment mechanism including a motor, a motor fixedly mounted on the right end of the support plate, the motor's shaft passing through the support plate and rotatably connected to the support plate, a screw fixedly connected to the left end of the motor's shaft, the screw rotatably connected to the support plate, the screw movably connected to the bracket, a top plate threadedly connected to the outside of the screw, and a spring mounted on the outside of the screw. The device uses a motor-driven screw to rotate and a top plate to perform a threaded movement. This causes the top plate to move by spring-loaded compression of the support, buffering the contact between the color-coated sheet and the saw wheel, preventing damage to the saw wheel teeth and ensuring its lifespan. The limiting mechanism includes a sliding plate, which is slidably connected inside the support. A clamping plate is fixedly connected to the lower end of the sliding plate, and a double-ended screw is threaded inside the sliding plate. A support column is fixedly connected to the surface of the support, and a sleeve is slidably connected to the outer side of the support column. A hanger is fixedly connected to the lower end of the sleeve, and a compression spring is installed inside the sleeve. A pressure strip is fixedly connected to the lower end of the hanger, and the pressure strip contacts the support plate. By rotating the double-ended screw and the sliding plate to perform a threaded movement, the distance between the two clamping plates changes, allowing the device to clamp and limit color-coated sheets of different widths. Simultaneously, the compression spring acts on the hanger, causing the pressure strip to elastically press the color-coated sheet onto the support plate, protecting the area near the cut and preventing warping at the cut edge.

[0006] Preferably, one end of the spring is fixedly connected to the bracket, and the other end of the spring is fixedly connected to the top plate. By setting the spring, the bracket is elastically compressed.

[0007] Preferably, a guide rod is fixedly connected to the surface of the top plate, and the guide rod and the bracket are slidably connected. By setting the guide rod, relative rotation between the top plate and the bracket is prevented.

[0008] Preferably, a limiting plate is fixedly connected to the upper end of the bracket, and the limiting plate is rotatably connected to the bidirectional screw. By setting the limiting plate, the bidirectional screw is prevented from moving out of control.

[0009] Preferably, one end of the compression spring is fixedly connected to the support column, and the other end of the compression spring is fixedly connected to the hanger. By setting the compression spring, the hanger is elastically compressed downwards.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a motor to drive the screw to rotate and the top plate to make a threaded movement, which in turn causes the top plate to move by spring elastic compression of the support. This buffers the contact between the color-coated sheet and the saw wheel, preventing the saw wheel teeth from being damaged by impact and ensuring the service life of the saw wheel.

[0012] 2. This utility model uses the rotation of the bidirectional screw and the sliding plate to make a threaded movement, thereby changing the distance between the two clamping plates. This allows the device to clamp and limit color-coated plates of different widths. At the same time, the pressure spring acts on the hanger, causing the pressure strip to elastically press the color-coated plate onto the support plate, protecting the area near the cut and preventing the cut from warping.

[0018] 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.

[0019] Please see Figures 1-2A cutting device for color-coated steel sheet production includes a workbench 1, a saw wheel 2 on the workbench 1, a support plate 3 slidably connected inside the workbench 1, a bracket 4 slidably connected to the outside of the workbench 1, a guide bar 5 fixedly connected inside the bracket 4, the guide bar 5 and the workbench 1 being slidably connected, a support plate 6 fixedly connected to the upper end of the workbench 1, an adjustment mechanism 7 on the support plate 6, and a limit mechanism 8 on the bracket 4.

[0020] Please see Figures 1-3 The adjusting mechanism 7 includes a motor 71. The motor 71 is fixedly installed on the right end of the support plate 6. The rotating shaft of the motor 71 passes through the support plate 6 and is rotatably connected to the support plate 6. A screw 72 is fixedly connected to the left end of the rotating shaft of the motor 71. The screw 72 is rotatably connected to the support plate 6 and movably connected to the bracket 4. A top plate 73 is threadedly connected to the outside of the screw 72. A spring 74 is provided on the outside of the screw 72. One end of the spring 74 is fixedly connected to the bracket 4, and the other end of the spring 74 is fixedly connected to the top plate 73. Next, by setting a spring 74, the bracket 4 is elastically compressed. A guide rod 75 is fixedly connected to the surface of the top plate 73. The guide rod 75 and the bracket 4 are slidably connected. By setting the guide rod 75, the relative rotation of the top plate 73 and the bracket 4 is prevented. The screw 72 is driven to rotate by the motor 71 and the top plate 73 makes a threaded movement. In turn, the top plate 73 is elastically compressed by the spring 74 to move the bracket 4. This buffers the contact between the color-coated plate and the saw wheel 2, avoids damage to the saw teeth of the saw wheel 2, and ensures the service life of the saw wheel 2.

[0021] Please see Figure 1 , Figure 2 , Figure 4 The limiting mechanism 8 includes a sliding plate 81, which is slidably connected inside the bracket 4. A clamping plate 82 is fixedly connected to the lower end of the sliding plate 81. A double-acting screw 83 is threadedly connected inside the sliding plate 81. A limiting plate 84 is fixedly connected to the upper end of the bracket 4. The limiting plate 84 and the double-acting screw 83 are rotatably connected. The limiting plate 84 prevents the double-acting screw 83 from moving. A support column 85 is fixedly connected to the surface of the bracket 4. A sleeve 86 is slidably connected to the outer side of the support column 85. A hanger 87 is fixedly connected to the lower end of the sleeve 86. A compression spring 88 is installed inside the sleeve 86. One end of the compression spring 88 is connected to the support column 85. The support column 85 is fixedly connected, and the other end of the compression spring 88 is fixedly connected to the hanger 87. By setting the compression spring 88, the hanger 87 is elastically pressed down. The lower end of the hanger 87 is fixedly connected to the pressure strip 89, which contacts the support plate 3. By rotating the bidirectional screw 83 and the slide plate 81 to make threaded movement, the distance between the two clamping plates 82 changes, so that the device can clamp and limit the color-coated plates of different widths. At the same time, the compression spring 88 acts on the hanger 87, so that the pressure strip 89 elastically presses the color-coated plate onto the support plate 3, protecting the area near the cut and preventing the cut from warping.

[0022] The specific implementation process of this utility model is as follows: In use, the upper hanger 87 is moved to disengage the pressure strip 89 from the tray 3. The hanger 87 moves to compress the spring 88, placing the color-coated plate on the tray 3. Then, the hanger 87 is released, and the spring 88 returns to its original position, causing the pressure strip 89 to press the color-coated plate onto the tray 3. Through the action of the spring 88 on the hanger 87, the pressure strip 89 elastically presses the color-coated plate onto the tray 3, protecting the area near the cut and preventing warping at the cut. Then, the bidirectional screw 83 is manually rotated. The rotating and sliding plate 81 make a threaded movement, which in turn changes the distance between the two clamping plates 82 and makes them contact the edge of the color-coated plate. This allows the device to clamp and limit color-coated plates of different widths, preventing positional displacement during the movement of the color-coated plate. Then, the motor 71 is started, which drives the screw 72 to rotate and the top plate 73 to make a threaded movement. This causes the top plate 73 to move by elastically pressing the bracket 4 through the spring 74, which buffers the movement of the color-coated plate when it comes into contact with the saw wheel 2, preventing the saw teeth of the saw wheel 2 from being damaged by impact and ensuring the service life of the saw wheel 2.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
