A workpiece 4 is provided on the upper surface of the transfer table 3, and a clamping assembly is provided on the front surface of the transfer table 3. The clamping assembly is used to clamp and limit the workpiece 4 to prevent its front and back offset. A cleaning assembly is provided on the upper surface of the machine table 1. The cleaning assembly is used to clean the sponge debris on the upper surface of the machine table 1. The clamping assembly includes a support table 51. The support table 51 is in an inverted U shape and is used to fix the motor 52 and the limiting rod 54. The support table 51 is fixed on the ground. A motor 52 is provided on the lower surface of the support table 51. The motor 52 is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The output shaft of the motor 52 is fixedly connected to a threaded rod 53. The upper surface of the support table 51 is fixedly connected to a limiting rod 54. There are two groups of limiting rods 54, and they are symmetrically distributed on the front and back sides of the upper surface of the support table 51 with the support table 51 as the axis of symmetry. The outer wall of the threaded rod 53 is threadedly connected to a connecting rod one 55. The threaded rod 53 penetrates through the upper surface of the connecting rod one 55. When the threaded rod 53 rotates, it will drive the connecting rod one 55 to move up or down. A wedge block 56 is fixedly connected to the upper surface of the connecting rod one 55.
[0033] Refer to Figure 2 , Figure 3 , the clamping assembly further includes two groups of fixing blocks one 57. The two groups of fixing blocks one 57 are symmetrically distributed on the front and back sides of the transfer table 3 with the transfer table 3 as the axis of symmetry. The front surface of the fixing block one 57 is elastically connected to an L block 58 through a spring 511. The front surface of the L block 58 is fixedly connected to a U block 59. A roller 510 is rotatably connected to the upper surface of the U block 59. There are two groups of rollers 510. The two groups of rollers 510 are symmetrically distributed on the left and right sides of the U block 59 with the U block 59 as the axis of symmetry. Each group of rollers 510 has two rollers. The two rollers 510 are symmetrically distributed on the upper and lower sides of the U block 59 with the U block 59 as the axis of symmetry.
[0034] Refer to Figure 4 , Figure 5, the cleaning component includes a second fixed block 61. The upper surface of the second fixed block 61 is provided with a telescopic rod 62. The telescopic rod 62 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The left surface of the telescopic rod 62 is fixedly connected to a second connecting rod 63. The left surface of the second connecting rod 63 is fixedly connected to a round rod 64. The left surface of the round rod 64 is fixedly connected to a push plate 65. The push plate 65 is in the shape of a long plate, and its length is equal to the width of the working area of the machine table 1.
[0035] Refer to Figure 1 , Figure 2 , there are two sets of transfer tables 3. The two sets of transfer tables 3 are symmetrically distributed on the left and right sides of the machine table 1 with the machine table 1 as the axis of symmetry. The limiting rod 54 penetrates and is slidably connected to the upper surface of the first connecting rod 55. There are two sets of wedge blocks 56. The two sets of wedge blocks 56 are symmetrically distributed on the front and rear sides of the first connecting rod 55 with the support table 51 as the axis of symmetry. The wedge blocks 56 are used to squeeze the L-shaped block 58 to make it move. The output shaft of the motor 52 penetrates the upper surface of the support table 51.
[0036] Refer to Figure 1 , Figure 3 , the first fixed block 57 is fixedly connected to the front surface of the transfer table 3. The rear surface of the wedge block 56 is a slope. The front surface of the L-shaped block 58 is semi-circular. The front surface of the L-shaped block 58 is in contact with the rear surface of the wedge block 56. When the wedge block 56 moves upward, it will squeeze the arc surface of the L-shaped block 58 and make the two L-shaped blocks 58 move relatively closer. The L-shaped block 58 penetrates and is slidably connected to the front surface of the first fixed block 57. One end of the spring 511 is fixedly connected to the front surface of the L-shaped block 58, and the other end of the spring 511 is fixedly connected to the rear surface of the first fixed block 57. When the L-shaped block 58 moves backward, it will stretch the spring 511 and make it generate a reaction force.
[0037] Refer to Figure 4 , Figure 5 , the second fixed block 61 is fixedly connected to the right surface of the machine table 1. There are two sets of round rods 64. The two sets of round rods 64 are symmetrically distributed on the front and rear sides of the second connecting rod 63 with the second connecting rod 63 as the axis of symmetry. The push plate 65 is slidably connected to the upper surface of the machine table 1. A notch is provided at the center position of the push plate 65. The notch of the push plate 65 is used to avoid the cutting line of the cutting device 2 when moving.
[0038] Working principle: When this device is in use, first place the workpiece 4 to be cut on the surface of the transfer table 3, and then start the motor 52 to drive the threaded rod 53 to rotate. The threaded rod 53 drives the first connecting rod 55 to move upward. Due to the limitation of the limiting rod 54, the first connecting rod 55 will remain stable during the upward movement. The first connecting rod 55 drives the wedge block 56 to move upward. When the wedge block 56 moves upward, it will squeeze the front surface of the L-shaped block 58, causing the L-shaped block 58 to move backward, so that the two L-shaped blocks 58 approach each other. When the L-shaped block 58 moves, it will stretch the spring 511 and generate a reaction force. The L-shaped block 58 drives the U-shaped block 59 to move backward, and the U-shaped block 59 drives the roller 510 to move backward. When the roller 510 touches the workpiece 4, turn off the motor 52, so that the workpiece 4 will be clamped by the roller 510. Then start the transfer table 3 to drive the workpiece 4 to move to the cutting area, and start the cutting device 2 for cutting. When the workpiece 4 moves, it will drive the roller 510 to rotate, reducing the frictional resistance when the workpiece 4 moves. And due to the limitation of the roller 510, the workpiece 4 will not shift due to force during cutting, ensuring the cutting accuracy.
[0039] The cut workpiece 4 will be taken away from the machine table 1 by another transfer table 3. At this time, start the motor 52 to drive the threaded rod 53 to rotate in the reverse direction, thereby driving the wedge block 56 to move downward. The wedge block 56 releases the extrusion on the L-shaped block 58, and the L-shaped block 58 resets under the reaction force of the spring 511, thereby driving the roller 510 back to the initial position. Then the cutting of the next workpiece 4 can be carried out.
[0040] After the device has been used for a period of time, sponge debris generated during cutting will accumulate on the upper surface of the machine table 1, affecting the working effect of the cutting device 2. At this time, move the position of the cutting device 2 to the middle of the machine table 1, and start the telescopic rod 62 to drive the second connecting rod 63 to move leftward. The second connecting rod 63 drives the round rod 64 to move, and the round rod 64 drives the push plate 65 to move synchronously. The push plate 65 pushes the sponge debris on the upper surface of the machine table 1 away from the machine table 1 so that it falls to the ground. Since the cutting device 2 is located at the center of the machine table 1, the notch in the center of the push plate 65 can pass through the cutting line, avoiding collision with the cutting line. Then the telescopic rod 62 drives the push plate 65 back to the initial position, completing the cleaning of the sponge debris.
[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
