DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figures 1 to 3 As shown, a left-right cloth disc cutter of the utility model comprises a base frame 10, a cutter frame 16 is arranged on the base frame 10, at least one guide rail 22 is horizontally arranged on the cutter frame 16, a disc cutter mechanism 18 is movably arranged on the guide rail 22, and also comprises a driving device 63 for driving the disc cutter mechanism 18 to move along the guide rail 22; the disc cutter mechanism 18 comprises a disc cutter 21 and a cutter motor 19 for driving the disc cutter 21 to rotate forward or reversely, and also comprises a switching device (not shown) for controlling the forward or reverse rotation of the cutter motor 19. During operation, the cloth is fed in and placed on the base frame 10. The driving device 63 drives the two disc cutter mechanisms 18 to move to the cutting position to cut the cloth. The disc cutter mechanism 18 moves within the length range of the guide rail 22, and the guide rail 22 acts as a limit support for the support plate 24 to prevent the disc cutter mechanism 18 from shaking during cutting. The cutter motor 19 is electrically connected to the switching device. The cutter motor 19 is a common DC motor. The forward and reverse rotation of the cutter motor 19 is controlled by changing the direction of the current. The switching device is a common single-chip switching device or a switching switch set at the end of the stroke at both ends of the disc cutter mechanism 18, etc., to control the disc cutter mechanism 18 to change the rotation direction during reciprocating cutting, thereby improving the cutting effect and cutting efficiency. The implementation of the switching device is a technology that is well known and widely used in the industry, and it is not the innovative point of the present invention itself, so it is not described in detail.

[0023] The disc cutter mechanism 18 also includes a fixing plate 23 connected to the output shaft neck of the cutter motor 19 , a support plate 24 arranged above the cutter motor 19 , and a guide groove 26 provided in the middle of the support plate 24 and cooperating with the guide rail 22 ; the bottom of the support plate 24 is connected to the fixing plate 23 .

[0024] The rotating mechanism 28 includes a top plate 32 extending from the fixed plate 23 to the top of the cutter motor 19, a first fixed shaft 34 and a first cylinder 36 arranged at the bottom of the supporting plate 24, the first fixed shaft 34 is rotatably connected to the top plate 32, a second fixed shaft 38 is also arranged on the top plate 32, and the output end of the first cylinder 36 is rotatably connected to the second fixed shaft 38. When adjusting the cutting angle, the output end of the first cylinder 36 drives the second fixed shaft 38 to make a circular motion around the first fixed shaft 34, and drives the top plate 32 and the disc cutter mechanism 18 to rotate accordingly. The first cylinder can also be a solenoid valve.

[0025] A side plate 40 for mounting a knife sharpening mechanism 30 is also provided on one side of the cutter motor 19. The knife sharpening mechanism 30 includes a mounting seat 42, a second cylinder 44 disposed on the mounting seat 42, and a grinding wheel 46 connected to the output end of the second cylinder 44. During grinding, the second cylinder 44 moves to adjust the grinding depth of the grinding wheel 46.

[0026] Furthermore, the mounting seat 42 is a bending structure, including a first bending portion 48 and a second bending portion 50. The first bending portion 48 is sleeved on the second cylinder 44. The second bending portion 50 is provided with a positioning connection hole 52 and a movable groove 54 for adjusting the grinding angle of the sharpening mechanism 30. The side plate is also provided with a plurality of mounting holes 68. The second bending portion 50 is rotatably connected to the side plate 40 through the positioning connection hole 52 and the movable groove 54. During installation, two bolts are used to connect the second bending portion 50 to the side plate 40 through the positioning connection hole 52 and the movable groove 54. The mounting seat 42 performs a circular motion around the positioning connection hole 52 within the range of the movable groove 54. At the same time, a suitable mounting hole 68 can also be selected according to the grinding range.

[0027] The third cylinder 60 for pressing cloth is arranged below the cloth pressing frame 12, and the movable end of the third cylinder 60 is provided with a cloth pressing block 62, and a half-surrounded knife cover 66 is also arranged on the disc cutter 21. During cutting, the output end of the third cylinder 60 extends to drive the cloth pressing block 62 to fix the cloth.

[0028] A plurality of rotating rollers 56 are provided on the cloth feeding rack 14, and spacers 58 for separating cloth are sleeved on the rotating rollers 56. The spacers 58 are movably provided on the rotating rollers 56, and the position of the spacers 58 can be adjusted according to the width of the cloth. The driving device 63 includes a synchronous belt 20 and a driving motor 64 for driving the synchronous belt to move. A synchronous wheel (not shown) is provided at the other end of the synchronous belt 20. The top of the support plate 24 is connected to the synchronous belt 20, and a groove for cutting cloth (not shown) is also provided on the bottom frame.

[0029] When the device is working, the position of the spacer 58 is adjusted according to the width of the cloth, and the cloth is fed in from the cloth feed rack 14. The output end of the third cylinder 60 extends to drive the cloth pressing block 62 to fix the cloth. The synchronous belt 20 drives the disc cutter mechanism 18 to move to the cutting position to cut the cloth. The switching device controls the forward and reverse rotation of the cutter motor 19 by changing the direction of the current. When the cloth is cut back and forth, the rotation direction of the cutter motor 19 is changed to reverse the disc cutter 21 to improve the cutting effect; the output end of the first cylinder 36 drives the top plate 32 and the cutter motor 19 to rotate around the first fixed axis 34 to adjust the cutting angle of the disc cutter 21; the sharpening mechanism 30 grinds the disc cutter 21 to prevent the disc cutter 21 from being blunted and affecting the cutting efficiency.
