[0037] Specifically, after the motor 205a inside the transmission assembly 205 is started, it can drive the screw 205b to rotate, so that after the screw 205b rotates, it can drive the screw sleeve 205c to move up and down inside the fixed groove 204, so that the screw sleeve 205c can drive the connecting plate 205d to move up and down, so that after the connecting plate 205d moves up and down, it can drive the tooth plate 206b to move up and down.

[0038] When the tooth plate 206b inside the rotating assembly 206 moves up and down, it drives the transmission sleeve 203 to rotate through the tooth groove 206a on the surface of the transmission sleeve 203, so that the surface of the fixed shaft 202 inside the installation groove 201 of the transmission sleeve 203 rotates and drives the cutting knife 106 to rotate.

[0039] The frustum block B can limit the bottom of the screw rod 205b, thereby ensuring the stability of the screw rod 205b during rotation.

[0040] Furthermore, when the cutting knife 106 needs to be polished and cleaned, the motor 205a inside the fixed groove 204 is started, so that the motor 205a can drive the screw 205b to rotate after starting, and the screw 205b can drive the screw sleeve 205c to move downward after the screw sleeve 205c moves downward, and the connecting plate 205d can be driven downward after the connecting plate 205d moves downward, and the tooth plate 206b can be matched with the tooth groove 206a on the transmission sleeve 203 on the surface of the fixed shaft 202 after the tooth plate 206b moves downward and engages with the tooth groove 206a, thereby driving the transmission sleeve 203 to rotate after the transmission sleeve 203 rotates, and the cutting knife 106 can be driven to rotate after the transmission sleeve 203 rotates.

[0041] Then, the motor 205a is started again, so that the motor 205a can drive the screw 205b to rotate after starting, and the screw 205b can drive the screw sleeve 205c to move upward after the screw sleeve 205c moves upward, and the connecting plate 205d can drive the connecting plate 205d to move upward after the connecting plate 205d moves upward, so that the tooth plate 206b can cooperate with the tooth groove 206a to drive the transmission sleeve 203 to rotate in the opposite direction, so that the transmission sleeve 203 can drive the cutting knife 106 to rotate in the opposite direction to reset, so that the cutting knife 106 can rotate in the opposite direction and cooperate with the grinding piece 302 moving to the left to grind the surface of the cutting knife 106 after rotating.

[0042] Example 3 Reference Figures 1 to 5 The third embodiment of the present invention provides a trimming device for cast film production, which uses a cleaning and polishing mechanism 300 to clean and polish the cutting blade 106 while it rotates.

[0043] The cleaning and polishing mechanism 300 includes a fixed frame 301, which is fixedly connected to the right side of the threaded sleeve 105. A polishing element 302 is movably connected to the top of the fixed frame 301, and a cleaning element 303 is movably connected to the bottom of the polishing element 302. Reset assemblies 304 are provided at the top and bottom of the front and rear inner walls of the fixed frame 301. A push assembly 305 is fixedly connected to the front side of the right side of the fixed frame 301, and a control assembly 306 is fixedly connected to the bottom of the threaded sleeve 105. The reset assembly 304 includes a movable groove 304a, and a tension spring 304b is fixedly connected to the right side of the inner wall of the movable groove 304a. The front and back sides of the grinding piece 302 and the cleaning piece 303 are fixedly connected with a reset block 304c, and the left end of the tension spring 304b is fixedly connected to the right side of the reset block 304c.

[0044] The control assembly 306 includes a fixed plate 306a, a first control button 306b is fixedly connected to the bottom right of the fixed plate 306a, and a second control button 306c is fixedly connected to the right side of the threaded sleeve 105. The first control button 306b and the second control button 306c are both movably connected to the cutting knife 106.

[0045] A reinforcement plate A is fixedly connected to the left side of the fixing plate 306 a , and the top of the reinforcement plate A is fixedly connected to the bottom of the threaded sleeve 105 .

[0046] The pushing assembly 305 includes a connecting seat 305a, the rear side of the connecting seat 305a is fixedly connected to an electric telescopic rod 305b, the surface of the fixed frame 301 is movably connected to a pushing frame 305c, the rear end of the electric telescopic rod 305b is fixedly connected to the pushing frame 305c, and the front side of the right side of the grinding part 302 and the rear side of the right side of the cleaning part 303 are both fixedly connected to a pushing plate 305d.

[0047] Specifically, the tension spring 304b in the movable groove 304a inside the reset assembly 304 will drive the reset block 304c to move to the right inside the movable groove 304a through its own tension, so that after the reset block 304c moves to the right, it can drive the cleaning part 303 and the polishing part 302 to move to the right inside the fixed frame 301, so that the cleaning part 303 and the polishing part 302 drive the push plate 305d to move to the right.

[0048] After the electric telescopic rod 305b on the internal connecting seat 305a of the pushing component 305 is started, it can drive the pushing frame 305c to move, so that the pushing frame 305c can contact the pushing plate 305d on the cleaning member 303 after moving to the rear side, thereby driving the cleaning member 303 to move to the left side through the pushing plate 305d, so that the cleaning member 303 can clean the surface of the rotating cutting knife 106 after moving to the left side. After the electric telescopic rod 305b is started, the pushing frame 305c can be driven to move forward and can contact the pushing plate 305d on the grinding member 302, so that the pushing plate 305d pushes the grinding member 302 to move to the left side, so that the grinding member 302 can grind the surface of the rotating cutting knife 106 after moving to the left side.

[0049] When the cutting knife 106 contacts the first control button 306b on the fixed plate 306a inside the control assembly 306, the electric telescopic rod 305b is activated, so that the electric telescopic rod 305b can drive the pushing frame 305c to move backward, so that the pushing frame 305c moving backward can cooperate with the pushing plate 305d to drive the cleaning member 303 to move to the left. When the cutting knife 106 contacts the second control button 306c, the electric telescopic rod 305b can be activated to drive the pushing frame 305c to move forward, so that the pushing frame 305c moving forward can cooperate with the pushing plate 305d to drive the grinding member 302 to move to the left.

[0050] The use of the reinforcement plate A can reinforce the fixing plate 306 a , thereby making the fixing plate 306 a more stable during use.

[0051] Furthermore, when the cutting knife 106 is cutting the edge of the cast film, the cutting knife is in contact with the first control button 306b on the fixed plate 306a, so that the first control button 306b can activate the electric telescopic rod 305b on the connecting seat 305a, so that the electric telescopic rod 305b can drive the pushing frame 305c to move toward the rear side after being activated, and when the pushing frame 305c moves toward the rear side, the pushing plate 305d on the cleaning member 303 will be used to push the cleaning member 303 to move to the left.

[0052] When it is necessary to polish and clean the cutting blade 106, the motor 205a inside the fixed groove 204 is started, so that the motor 205a can drive the screw rod 205b to rotate after starting, and the screw sleeve 205c can be driven to move downward after the screw sleeve 205c moves downward, and the connecting plate 205d can be driven downward after the connecting plate 205d moves downward, and the tooth plate 206b can be driven downward to match the tooth groove 206a on the transmission sleeve 203 on the surface of the fixed shaft 202, so that the tooth plate 206b moves downward and engages with the tooth groove 206a, and then drives the transmission sleeve 203 to rotate, and the rotation of the transmission sleeve 203 can drive the cutting blade 106 to rotate.

[0053] After the cutting blade 106 rotates, it will contact the cleaning member 303 inside the fixing frame 301. As the cutting blade 106 continues to rotate, the cleaning member 303 will clean and scrape away the dirt and impurities on the surface of the cutting blade 106. At this time, the cutting blade 106 will contact the second control button 306c. At this time, the second control button 306c will activate the electric telescopic rod 305b, so that the electric telescopic rod 305b can drive the pushing frame 305c to move forward after being activated. After the pushing frame 305c moves forward, it can drive the grinding member 302 to move to the left through the pushing plate 305d. At this time, the pushing frame 305c will separate from the pushing plate 305d on the cleaning member 303.

[0054] At this time, the cutting knife 106 will contact the second control button 306c on the fixed plate 306a, so that the second control button 306c can activate the electric telescopic rod 305b to drive the pushing frame 305c to move backward, so that the electric telescopic rod 305b can drive the pushing frame 305c to move backward. When the pushing frame 305c moves backward, it will push the cleaning member 303 to the left through the pushing plate 305d on the cleaning member 303.

[0055] The remaining structures are the same as those of Example 2.

[0056] Example 4 Reference Figures 1 to 5 , which is the fourth embodiment of the present invention, is different from the third embodiment in that: a trimming device for cast film production.

[0057] When the cutting knife 106 is cutting the edge of the cast film, the cutting knife 106 is in contact with the first control button 306b on the fixed plate 306a, so that the first control button 306b can activate the electric telescopic rod 305b on the connecting seat 305a, so that the electric telescopic rod 305b can drive the pushing frame 305c to move backward after being activated. When the pushing frame 305c moves backward, the pushing plate 305d on the cleaning member 303 will be used to push the cleaning member 303 to move to the left.

[0058] When it is necessary to polish and clean the cutting blade 106, the motor 205a inside the fixed groove 204 is started, so that the motor 205a can drive the screw rod 205b to rotate after starting, and the screw sleeve 205c can be driven to move downward after the screw sleeve 205c moves downward, and the connecting plate 205d can be driven downward after the connecting plate 205d moves downward, and the tooth plate 206b can be driven downward to match the tooth groove 206a on the transmission sleeve 203 on the surface of the fixed shaft 202, so that the tooth plate 206b moves downward and engages with the tooth groove 206a, and then drives the transmission sleeve 203 to rotate, and the rotation of the transmission sleeve 203 can drive the cutting blade 106 to rotate.

[0059] After the cutting blade 106 rotates, it will contact the cleaning member 303 inside the fixing frame 301. As the cutting blade 106 continues to rotate, the cleaning member 303 will clean and scrape away the dirt and impurities on the surface of the cutting blade 106. At this time, the cutting blade 106 will contact the second control button 306c. At this time, the second control button 306c will activate the electric telescopic rod 305b, so that the electric telescopic rod 305b can drive the pushing frame 305c to move forward after being activated. After the pushing frame 305c moves forward, it can drive the grinding member 302 to move to the left through the pushing plate 305d. At this time, the pushing frame 305c will separate from the pushing plate 305d on the cleaning member 303.

[0060] At the same time, when the pushing frame 305c is separated from the pushing plate 305d on the cleaning frame, the tension spring 304b inside the movable groove 304a will drive the reset block 304c to move to the right through its own tension, so that the reset block 304c can drive the cleaning member 303 to reset after moving to the right.

[0061] Then, the motor 205a is started again, so that the motor 205a can drive the screw 205b to rotate after starting, and the screw 205b can drive the screw sleeve 205c to move upward after the screw sleeve 205c moves upward, and the connecting plate 205d can drive the connecting plate 205d to move upward after the connecting plate 205d moves upward, so that the tooth plate 206b can cooperate with the tooth groove 206a to drive the transmission sleeve 203 to rotate in the opposite direction, so that the transmission sleeve 203 can drive the cutting knife 106 to rotate in the opposite direction to reset, so that the cutting knife 106 can rotate in the opposite direction and cooperate with the grinding piece 302 moving to the left to grind the surface of the cutting knife 106 after rotating.

[0062] At this time, the cutting knife 106 will contact the second control button 306c on the fixed plate 306a, so that the second control button 306c can activate the electric telescopic rod 305b to drive the pushing frame 305c to move backward, so that the electric telescopic rod 305b can drive the pushing frame 305c to move backward. When the pushing frame 305c moves backward, it will push the cleaning member 303 to the left through the pushing plate 305d on the cleaning member 303.

[0063] In summary, the transmission assembly 205 inside the rotating mechanism 200 cooperates with the rotating assembly 206 to drive the cutting knife 106 to rotate, so that the grinding member 302 and the cleaning member inside the cleaning and grinding mechanism 300 can clean and grind the rotating cutting knife 106.
