The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figure 1 As shown, an automatic slitting type casting machine includes an unwinding mechanism 1, a head 2, an oven 3, a correction mechanism 4, a traction mechanism 5, and a circular knife slitting mechanism 6; the unwinding mechanism 1 is used to place a material roll, and then drive a material strip 7 into the head 2, the head 2 is installed at the output end of the material strip of the unwinding mechanism 1, and is used to coat the material strip 7 with slurry, the oven 3 is installed at the output end of the material strip 7 coated with slurry of the head 2, and is used to dry the material strip coated with slurry, the correction mechanism 4 is installed at the output end of the drying material strip of the oven 3, and is used to correct the drying material strip, the traction mechanism 5 is installed at the material strip output end of the correction mechanism 4, and is used to pull the material strip into the circular knife slitting mechanism 6, and the circular knife slitting mechanism 6 is installed at the material strip output end of the traction mechanism 5, and is used to slit the material strip 7;

[0033] like Figure 2 As shown, the circular knife slitting mechanism 6 includes a mounting seat 61, an upper circular knife assembly 62, a lower circular knife assembly 63, and at least two winding rollers 64; the upper circular knife assembly 62 and the lower circular knife assembly 63 are respectively installed at preset positions of the mounting seat 61 and the upper circular knife assembly 62 and the lower circular knife assembly 63 have a preset gap for accommodating the material strip 7 to be cut, and the two winding rollers 64 are rotatably arranged on the mounting seat 61 along the material strip output end between the upper circular knife assembly 62 and the lower circular knife assembly 63, for winding up the material strip 7 after slitting.

[0034] In one embodiment, the upper circular knife assembly 62 includes an upper circular knife fixing seat 621 and at least three upper circular knife sub-assemblies 622. The upper circular knife assembly 62 is mounted on the mounting seat 61. The three upper circular knife sub-assemblies 622 are detachably mounted on the upper circular knife fixing seat 621 at preset intervals.

[0035] The lower circular knife assembly 63 includes a lower circular knife mounting seat 631, a first motor 632, a lower circular knife shaft 633 and the same number of lower circular knives 634 as the upper circular knife sub-assembly 622. The lower circular knife mounting seat 631 is installed on the mounting seat 61, the first motor 632 is installed on the lower circular knife mounting seat 631 and is rotatably connected to the lower circular knife shaft 633, and the lower circular knife 634 is sleeved on the lower circular knife shaft 633 and is arranged corresponding to the upper circular knife sub-assembly 622.

[0036] like Figure 3 As shown, the upper circular knife subassembly 622 includes an upper circular knife mounting seat 6221 and an upper circular knife 6222. The upper circular knife mounting seat 6221 is slidably mounted on the upper circular knife fixing seat 621, and the upper circular knife 6222 is rotatably mounted on the upper circular knife mounting seat 6221. The upper circular knife mounting seat 6221 has a handle screw. When the upper circular knife mounting seat 6221 needs to be fixed to the upper circular knife fixing seat 621, the handle screw 6223 is rotated so that one end of the handle screw 6223 abuts against the top of the upper circular knife fixing seat 621, preventing the upper circular knife mounting seat 6221 from moving on the upper circular knife fixing seat 621. The number and position of the upper circular knives 6222 and the lower circular knife 634 are adapted, and a gap is provided between the upper circular knife 6222 and the lower circular knife 634 for the passage of the material strip.

[0037] When the material roll needs to be cast, the material roll is placed on the unwinding mechanism 1, the output end of the material belt 7 is placed on the machine head 2, and the unwinding mechanism 1 is started. The material belt 7 is coated with slurry from the machine head 2 on one side of the material belt 7 during the movement of the machine head 2. The material belt 7 coated with slurry enters the oven 3 from the machine head 2 for drying. After the dried material belt is removed from the oven 3, it enters the correction mechanism 4 for correction. After the correction is completed, the dried material belt 7 enters the traction mechanism 5. The traction mechanism 5 pulls the material belt 7 into the circular knife slitting mechanism 6 for slitting. The traction mechanism 5 pulls the material belt 7 into the upper circular knife 6222 and the lower circular knife 6 34, start the first motor 632, the first motor 632 drives the lower circular knife shaft 633 to rotate, and then drives the lower circular knife 634 to rotate through the lower circular knife shaft 633, and the lower circular knife shaft 633 can drive the material strip 7 to move while rotating. During the movement, the material strip 7 drives the upper circular knife 6222 to rotate together, and the middle upper circular knife 6222 cooperates with the lower circular knife 634 to complete the slitting of the material strip 7, and the upper circular knives 6222 and the lower circular knives 634 on both sides cooperate to complete the edge trimming of the material strip 7. The slitting of the material strip 7 is placed on two winding rollers 64 for winding.

[0038] In this way, the automatic slitting type casting machine is arranged through the coordination of the unwinding mechanism 1, the machine head 2, the oven 3, the correction mechanism 4, the traction mechanism 5, and the circular knife slitting mechanism 6. The circular knife slitting mechanism 6 includes an upper circular knife assembly 62, a lower circular knife assembly 63, and at least two winding rollers 64. The upper circular knife assembly 62 includes three upper circular knife sub-assemblies 622. When it is necessary to cut sheets of material of different widths, the positions of the three upper circular knife sub-assemblies 622 and the corresponding lower circular knife assemblies 63 can be moved to complete the slitting of sheets of material of different widths. At the same time, when the middle upper circular knife sub-assembly 622 cooperates with the lower circular knife assembly 63 to complete the slitting of the material strip 7, the upper circular knife sub-assemblies 622 and the lower circular knife assembly 63 on both sides cooperate to complete the edge trimming of the material strip 7. There is no need to use another edge trimming machine for edge trimming, which improves the efficiency of the casting process.

[0039] like Figure 4 As shown, in one embodiment, the circular knife slitting mechanism 6 also includes a dust suction component 65, and the dust suction component 65 includes an upper dust suction pipe 651 and a lower dust suction pipe 652. The upper dust suction pipe 651 is passed through the upper circular knife mounting seat 6221 and is connected to the lower dust suction pipe 652. The lower dust suction pipe 652 has a suction nozzle at one end close to the lower circular knife shaft 633.

[0040] Thus, one end of the upper dust suction pipe 651 is connected to the vacuum cleaner, and the other end is connected to the lower dust suction pipe 652. The lower dust suction pipe 652 has a suction nozzle at the end near the lower circular blade shaft 633. The suction nozzle is used to absorb impurities and dust generated during the slitting of the material strip 7. When vacuuming is required, the vacuum cleaner is activated to suck away impurities and dust generated during the slitting of the material strip 7 through the upper dust suction pipe 651, the lower dust suction pipe 652, and the suction nozzle, thereby ensuring the cleanliness of the material strip 7.

[0041] In one embodiment, the circular knife slitting mechanism 6 further includes a dust removal brush 66 , which is mounted on the lower circular knife mounting seat 631 and abuts against the material strip 7 .

[0042] In this way, when the material belt 7 is driven to move by the lower circular knife shaft 633, the dust removal brush 66 contacts the material belt 7, brushing off the dust or impurities on the material belt 7, ensuring that the material belt 7 is clean and tidy.

[0043] like Figure 5 As shown, in one embodiment, the unwinding mechanism 1 includes an unwinding mounting seat 11 and a pinching roller 12 . The pinching roller 12 is rotatably disposed on the unwinding mounting seat 11 , and the material roll is mounted on the pinching roller 12 .

[0044] In this way, the material roll is placed on the pinch roller 12, and the pinch roller 12 can be driven to rotate by an external motor. During the rotation of the pinch roller 12, the material belt 7 on the material roll is driven to move toward the machine head 2.

[0045] like Figure 6 As shown, in one embodiment, the machine head 2 includes a mounting bracket 21, two lifting cylinders 22, a sliding assembly 23, a die rotation assembly 24, and two die heads 25. The sliding assembly 23 is installed on the mounting bracket 21, and the die rotation assembly 24 is slidably set on the sliding assembly 23, and is used to drive the two die heads 25 to rotate. The two die heads 25 are respectively installed on the top and bottom of the die rotation assembly 24, and the two lifting cylinders 22 are symmetrically arranged on the mounting bracket 21 and the telescopic rod is fixedly connected to the die rotation assembly 24, and is used to drive the die rotation assembly 24 and the two die heads 25 to move in the vertical direction.

[0046] The sliding assembly 23 includes a base 231, a slide rail 232 and a slider 233. The slide rail 232 is fixedly mounted on the base 231, and the slider 233 is slidably disposed on the slide rail 232.

[0047] like Figure 7 As shown, the die head rotation assembly 24 includes two fixed seats 241, a mounting seat 242, a rotating handle 243, and a rotating shaft 244. The two fixed seats 241 are symmetrically arranged on the mounting bracket 21. The rotating shaft 244 is passed through the mounting seat 242 and both ends are rotatably arranged on the two fixed seats 241. The rotating handle 243 is installed at one end of the rotating shaft 244, and is used to drive the rotating shaft 244 to rotate while driving the mounting seat 242 to rotate together. The two die heads 25 are respectively installed on the top and bottom surfaces of the mounting seat 242.

[0048] The two die heads 25 are respectively arranged at the top and bottom of the mounting base 242. The top die head 25 is responsible for coating the slurry on the material belt 7 of the coating roller. When it is necessary to change different coating slurries, the rotating handle 243 is turned, and the rotating handle 243 drives the rotating shaft 244 to rotate synchronously. The rotating shaft 244 drives the mounting base 242 to rotate 180 degrees synchronously, so that the positions of the original bottom die head 25 and the original top die head 25 are exchanged, and the two lifting cylinders 22 are started. The two lifting cylinders 22 push the die head rotation group The component 24 moves toward the coating roller, and one of the fixed seats 241 slides toward the coating roller on the slide rail 232 through the slider 233, so that the mounting seat 242 drives the two die heads 25 to move toward the coating roller until the distance between the replaced top die head 25 and the coating roller reaches a preset distance. The switched top die head 25 can add new slurry to coat the material strip 7. After the switching is completed, the bottom die head 25 can be disassembled for cleaning and then reinstalled for use, which significantly improves the coating efficiency.

[0049] like Figure 8As shown, in one embodiment, the head 2 also includes a spacing adjustment component 26, and the spacing adjustment component 26 includes a linear motor 261, a pressure block 262 and a wedge block 263. The linear motor 261 is installed on the mounting bracket 21, and one end of the pressure block 262 is fixedly connected to the output end of the linear motor 261. The wedge block 263 is fixedly installed on the die head rotation component 24. The top surface of the wedge block 263 is a slope structure. When the lifting cylinder 22 drives the die head rotation component 24 to move toward the spacing adjustment component 26, the top surface of the wedge block 263 is in contact with the bottom surface of the pressure block 262. When the linear motor 261 drives the pressure block 262 to slide on the top surface of the wedge block 263, the die head rotation component 24 is driven to move axially.

[0050] In this way, when it is necessary to fine-tune the distance between the die head 25 and the coating roller 8, the linear motor 261 is started, and the linear motor 261 drives the pressure block 262 to slide on the top surface of the wedge block 263. Because the top surface of the wedge block 263 is a sloped structure, when the distance between the die head 25 and the coating roller 8 needs to be expanded, the linear motor 261 drives the pressure block 262 to slide toward the high surface of the wedge block 263, applying a certain pressure to the mounting seat 242, causing the mounting seat 242 to slide toward the direction of the lifting cylinder 22, thereby driving the top die head 25 toward the direction of the lifting cylinder 22. Sliding, so that the distance between the top die head 25 and the coating roller 8 is expanded; when the distance between the die head 25 and the coating roller 8 needs to be reduced, the linear motor 261 drives the pressure block 262 to slide toward the lower surface of the wedge block 263, reducing the pressure on the mounting seat 242, causing the mounting seat 242 to slide in the direction away from the lifting cylinder 22, thereby driving the top die head 25 to slide in the direction away from the lifting cylinder 22, thereby reducing the distance between the top die head 25 and the coating roller 8, and realizing fine adjustment of the distance between the die head 25 and the coating roller 8, thereby adjusting the coating thickness of the material strip 7.

[0051] like Figure 9 As shown, in one embodiment, the correction mechanism 4 includes a correction mounting seat 41, a push rod motor, a correction roller 42, a traction roller 43, and a sensor 44. The correction roller 42 and the traction roller 43 are rotatably arranged on the correction mounting seat 41. The push rod motor is installed on the correction mounting seat 41 and is fixedly connected to one end of the correction roller 42 for controlling the axial movement of the correction roller 42. The sensor 44 is installed on the correction mounting seat 41 and has a gap with the correction roller 42. The drying material belt 7 is sleeved on the correction roller 42 and then sleeved on the traction roller 43 after passing through the gap.

[0052] The correction roller 42 can be one or two,

[0053] In this way, after the drying material belt 7 enters the correcting mechanism 4, it first enters the correcting roller 42, and after passing the correcting roller 42, it enters the traction roller 43 from the gap between the sensor 44 and the correcting roller 42. The traction roller 43 drives the material belt 7 to continue to move. The sensor 44 detects in real time whether the conveying position of the material belt 7 is offset, and sends the detection result to the control module. If the conveying position of the material belt 7 is offset, the control module sends a control signal to the push rod motor, and the push rod motor controls the correcting roller 42 to move along its own axial direction, so that the material belt 7 moves along the axial direction of the correcting roller 42 until the position is no longer offset. The push rod motor stops and the correcting roller 42 no longer moves axially.

[0054] like Figure 10 As shown, in one embodiment, the traction mechanism 5 includes a traction mounting seat 51 and an adsorption roller 52, the adsorption roller 52 is rotatably set on the traction mounting seat 51, the material strip 7 is sleeved on the adsorption roller 52, and the adsorption roller 52 drives the material strip 7 into the circular knife slitting mechanism 6 for slitting.

[0055] In this way, the material strip 7 can be adsorbed on the adsorption roller 52, and the adsorption roller 52 is driven to rotate by the motor. The adsorption roller 52 drives the material strip 7 to move during the rotation process, and then the material strip 7 enters the circular knife slitting mechanism 6 for slitting.

[0056] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
