[0001] The utility model relates to the technical field of tape casting machines, in particular to a circular knife slitting mechanism of an automatic slitting type tape casting machine. Background Art

[0002] A tape casting machine is a specialized device used to produce cast film. Using high-precision electronic ceramic tape casting machines, alumina is used as the primary raw material for ceramic film casting. First, crushed powder is mixed with a binder, plasticizer, dispersant, and solvent to create a slurry with a certain viscosity. The slurry flows from a hopper and is applied to a specialized base tape using a scraper to a desired thickness. After drying and curing, the green tape is peeled off from the top to form a film. The green tape is then processed through punching, lamination, and other processes to create the finished product ready for sintering. Advantages include low cost, high quality, non-toxicity, and a simple production process.

[0003] When the current casting machine's slitting structure is used to slit the film, since the slitting structure is fixed on the casting machine, it can only cut sheets of fixed size and width, which limits its use and makes it impossible to complete the edge trimming of the film. If the film needs to be trimmed, additional equipment is required, resulting in low overall processing efficiency. Utility Model Content

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, a circular knife slitting mechanism of an automatic slitting type casting machine includes a mounting base 1, an upper circular knife assembly 2 and a lower circular knife assembly 3;

[0024] The upper circular knife assembly 2 includes an upper circular knife fixing seat 21 and at least three upper circular knife sub-assemblies 22. The upper circular knife assembly 2 is mounted on the mounting seat 1. The three upper circular knife sub-assemblies 22 are detachably mounted on the upper circular knife fixing seat 21 at preset intervals.

[0025] The upper circular knife subassembly 22 includes an upper circular knife mounting seat 221 and an upper circular knife 222, and the upper circular knife 222 is rotatably mounted on the upper circular knife mounting seat 221;

[0026] The lower circular knife assembly 3 includes a lower circular knife mounting seat 31, a motor 32, a lower circular knife shaft 33 and the same number of lower circular knives 34 as the upper circular knife 222. The lower circular knife mounting seat 31 is mounted on the mounting seat 1, the motor 32 is mounted on the lower circular knife mounting seat 31 and is rotatably connected to the lower circular knife shaft 33. The lower circular knife 34 is sleeved on the lower circular knife shaft 33 and is correspondingly arranged with the upper circular knife 222. A preset gap is provided between the upper circular knife 222 and the lower circular knife 34 for accommodating the film 4 to be cut;

[0027] The mounting portion of the upper circular knife fixing seat 21 is a dovetail groove 211, and the upper circular knife mounting seat 221 can slide on the dovetail groove 211 when it is not fixed; the upper circular knife mounting seat 221 is provided with a handle screw 223, and when the upper circular knife mounting seat 221 needs to be fixed to the dovetail groove 211, the handle screw 223 is rotated so that one end of the handle screw 223 abuts against the top of the dovetail groove 211, so that the upper circular knife mounting seat 221 cannot move on the upper circular knife fixing seat 21.

[0028] The upper circular knife fixing seat 21 is arranged parallel to the lower circular knife shaft 33, and the upper circular knife subassemblies 22 are set to at least three, which are arranged on the upper circular knife fixing seat 21 according to preset distances. The middle upper circular knife subassembly 22 is used to cut the film 4, and the upper circular knife subassemblies 22 on both sides are used to trim the film 4. The upper circular knife 222 is rotatably mounted on the upper circular knife mounting seat 221, and the upper circular knife 222 is driven to rotate by the movement of the film 4. The lower circular knife 34 corresponds to the upper circular knife 222 and is detachably mounted on the lower circular knife shaft 33. The position of the lower circular knife 34 can be adjusted according to the position of the upper circular knife 222, and the upper circular knife 222 and the lower circular knife 34 are always kept in corresponding arrangement, so that the two sides of the film 4 are respectively in contact with the upper circular knife 222 and the lower circular knife 34. The middle upper circular knife 222 and the lower circular knife 34 are generally located at the center line position of the film 4, and the film 4 is cut into equal parts. The upper circular knives 222 and the lower circular knives 34 on both sides are located at the edges of the film 4, and the specific positions are determined according to the width of the cutting edge.

[0029] The upper circular knife mounting seat 221 is slidably mounted on the mounting portion of the upper circular knife fixing seat 21. The mounting portion of the upper circular knife fixing seat 21 is a dovetail groove 211 structure, which allows the upper circular knife mounting seat 221 to slide along the length direction of the upper circular knife fixing seat 21. When the upper circular knife mounting seat 221 needs to be fixed, the handle screw 223 is turned so that the bottom of the handle screw 223 abuts against the dovetail groove 211, so that the upper circular knife mounting seat 221 cannot slide on the upper circular knife fixing seat 21.

[0030] When the film 4 needs to be cut, the film 4 is placed on the lower circular blade shaft 33, so that the upper circular blades 222 and the lower circular blades 34 are respectively in contact with the two sides of the film 4. The motor 32 is started, and the motor 32 drives the lower circular blade shaft 33 to rotate. The lower circular blade shaft 33 drives the film 4 to move, and the film 4 drives the upper circular blade 222 to rotate. Under the joint action of the upper circular blade 222 and the corresponding lower circular blade 34, the film 4 is cut. The upper circular blade 222 and the lower circular blade 34 in the middle cut the film 4, and the upper circular blades 222 and the lower circular blades 34 on both sides are located at the edges of the film 4 to trim the film 4. The corresponding positions of the upper circular blades 222 and the lower circular blades 34 can be adjusted according to the width of the film 4 to meet the requirements of cutting different film 4 sizes.

[0031] When the motor 32 drives the lower circular knife shaft 33 to rotate, the lower circular knife shaft 33 drives the film 4 to move, and the film 4 drives the upper circular knife 222 to rotate. The film 4 is cut under the joint action of the middle upper circular knife 222 and the corresponding lower circular knife 34. The upper circular knife 222 and the corresponding lower circular knife 34 on both sides complete the edge cutting. When it is necessary to cut sheets of different widths, the positions of the three upper circular knife assemblies 22 and the corresponding lower circular knife assemblies 3 can be moved to complete the cutting of sheets of film 4 of different widths, thereby improving the processing efficiency.

[0032] In one embodiment, the circular knife slitting mechanism also includes a dust suction component 5, and the dust suction component 5 includes an upper dust suction pipe 51 and a lower dust suction pipe 52. The upper dust suction pipe 51 is passed through the upper circular knife mounting seat 221 and is connected to the lower dust suction pipe 52. The lower dust suction pipe 52 has a suction nozzle at one end close to the lower circular knife shaft 33.

[0033] Thus, one end of the upper dust suction pipe 51 is connected to the dust collector, and the other end is connected to the lower dust suction pipe 52. The lower dust suction pipe 52 has a suction nozzle at the end near the lower circular blade shaft 33. The suction nozzle is used to absorb impurities or dust generated during the slitting of the film 4. When dust collection is required, the vacuum cleaner is started to suck away impurities or dust generated during the slitting of the film 4 through the upper dust suction pipe 51, the lower dust suction pipe 52 and the suction nozzle, thereby ensuring the cleanliness of the film 4.

[0034] In one embodiment, the circular knife slitting mechanism further includes a dust removal brush 6 , which is mounted on the lower circular knife mounting seat 31 and abuts against the film 4 , and the dust removal brush 6 is a wool brush.

[0035] In this way, when the film 4 is driven to move by the lower circular knife shaft 33, the dust removal brush 6 contacts the film 4 to brush off the dust or impurities on the film 4, ensuring that the film 4 is clean and tidy.

[0036] In one embodiment, the circular knife slitting mechanism further includes a static elimination rod 7 , and the static elimination rod 7 is installed on the mounting base 1 .

[0037] In this way, the static electricity removal rod 7 mainly uses ionization technology to ionize air molecules into positive and negative ions, and neutralizes the surrounding static charges under the action of ion wind, thereby eliminating the static electricity generated on the film 4.

[0038] In one embodiment, the upper circular blade mounting seat 221 has an upper circular blade protection shell 2211 , and the upper circular blade protection shell 2211 has a notch 22111 at one end close to the lower circular blade shaft 33 .

[0039] In this way, by having a notch 22111 at one end of the upper circular knife protective shell 2211 close to the lower circular knife shaft 33, the blade is exposed only at the position where the upper circular knife 222 cuts the film 4, and the upper circular knife 222 is sealed by the upper circular knife protective shell 2211 at other non-cutting positions, avoiding contact between the upper circular knife 222 and other objects during cutting, which would cause damage to the upper circular knife 222.

[0040] 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.
