Description

Technical Field

[0001] This utility model relates to the field of combined cutter head technology, specifically a combined cutting cutter head. Background Technology

[0002] Combination cutting blades mostly refer to blade heads that allow for changes in cutting radius and material by replacing the blade head. For example, CN202321718930.1 describes a combination cutting blade for blow molding pipes, where the blade is bolted to the blade holder. Similar to this application, both the blade holder and blade head serve to connect the blade. This necessitates preparing replacement materials in advance when needed. While smaller blades don't significantly impact cutting, using high-quality blades, even with symmetrical installation, can cause the keyed blade head to deflect. Furthermore, the blade holder in the prior art lacks cutting capability, serving only as a mounting base for the blade, resulting in limited functionality. Therefore, we provide a combination cutting blade head to address these issues. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a combined cutting disc to solve the technical problem that installing blades on one side of the combined cutting disc causes mass eccentricity, thereby affecting the balance of the cutting disc installation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A combined cutting disc includes a base, with an annular cutting edge on the outer side of the base and a central mounting hole in the middle.

[0006] A dividing strip is installed on one side of the substrate. Multiple sets of dividing strips are arranged circumferentially on the outside of the central mounting hole. At least two sets of positioning holes are opened between adjacent dividing strips, and an enlarging cutting plate is installed on the positioning hole.

[0007] A counterweight is installed on the other side of the base, and the counterweight is detachably connected to the base.

[0008] In a further technical solution, the length of the dividing strip is no more than 2 / 3 of the base radius, one end of the dividing strip extends to the central mounting hole, and the other end is not in contact with the outer edge of the base.

[0009] In a further technical solution, the diameter-expanding cutting plate includes a blade body and a cutting edge. The blade body has a second positioning hole, and the first positioning hole and the second positioning hole are connected by a positioning bolt. The thickness of the blade body is consistent with that of the dividing strip.

[0010] The cutting edge is located on the side of the blade that faces away from the central mounting hole; the edge of the cutting edge facing the blade is coaxial with the central mounting hole.

[0011] The dividing strips on both sides of the diameter-expanding cutting plate are provided with bent plates, which are fixedly connected to the side of the dividing strip opposite to the diameter-expanding cutting plate.

[0012] In a further technical solution, the adjacent dividing strips are not arranged in parallel, and the bottom sides of the blade part are movably abutted between the corresponding dividing strips; and at least two sets of positioning holes are provided on the blade part.

[0013] In a further technical solution, the bending plate has two sets of notches, and limit block one and limit block two are fixedly installed on the dividing strip in the notches; a telescopic component is fixedly installed on the blade, and the telescopic component moves up and down to be restricted between limit block one and limit block two;

[0014] The corresponding diameter-expanding cutting plate is provided with positions A and B on the substrate respectively. At position A, the cutting edge does not extend into a circular cutting edge; at position B, the cutting edge extends into a circular cutting edge.

[0015] In a further technical solution, the cutting edge includes an external serration or an externally curved plate. When the cutting edge is an external serration, both ends of the external serration are sharpened. When the cutting edge is an externally curved plate, multiple sets of externally curved plates are sharpened in the same direction.

[0016] In a further technical solution, the telescopic component includes a cylindrical body and a telescopic column. Cavities are provided at both ends of the cylindrical body, and telescopic columns are installed thereon. A load-bearing spring is installed between the telescopic column and the inner wall of the cavity. One end of the load-bearing spring is fixedly connected to the telescopic column, and the other end is fixedly connected to the inner wall of the cylindrical body.

[0017] In a further technical solution, a balance cylinder is installed outside the balance block, and multiple sets of balance blocks are installed inside the balance cylinder. A threaded hole is provided on the balance block. A threaded hole is provided on the balance cylinder, and a locking bolt is installed between the threaded hole and the threaded hole.

[0018] Compared with existing technologies, it has the following advantages:

[0019] In this embodiment, a detachable expanding cutting disc is installed on one side of the base to enable the cutting disc to perform both rotary cutting and sawing functions, thereby increasing the cutting material that the cutting disc can cut. A balance plate is installed on the other side to maintain the balance of the two sides of the cutting disc and prevent one side from being too heavy, which would cause the disc to deflect on the shaft.

[0020] This invention features a telescopic column that moves between limiting block one and limiting block two. In both positions, the telescopic column is held in place by either limiting block one or limiting block two. A supporting spring keeps the end of the telescopic column abutting against the corresponding dividing strip as the diameter-expanding cutting plate moves. This telescopic component controls the movement distance of the diameter-expanding cutting plate, enabling rapid movement and quick positioning via positioning holes one and two, facilitating quick disassembly and fixation of the diameter-expanding cutting plate.

[0040] Please see Figure 1-5 This utility model provides a technical solution: a combined cutting disc, including a base 1, a circular cutting edge 2 on the outer side of the base 1, and a central mounting hole 3 in the middle; the circular cutting edge refers to a cutting edge with an acute angle in cross section, which has the conventional cutting effect.

[0041] A dividing strip 4 is installed on one side of the base 1. Multiple sets of dividing strips 4 are arranged circumferentially on the outside of the central mounting hole 3. At least two sets of positioning holes 5 are opened between adjacent dividing strips 4, and an enlarging cutting plate 6 is installed on the positioning holes 5.

[0042] A balance block 7 is installed on the other side of the base 1, and the balance block 7 is detachably connected to the base 1. In this embodiment, a detachable enlarged diameter cutting disc is set on one side of the base to realize that the cutting disc has both rotary cutting and sawing functions. The enlarged cutting disc can cut materials with low hardness, such as fruits, vegetables, meat slices and paper, and can also be used to cut materials such as leather and frozen meat. A balance plate is installed on the other side to maintain the balance of the two sides of the cutting disc and prevent one side from being too heavy and causing deflection on the shaft.

[0043] The length of the dividing strip 4 is no greater than 2 / 3 of the radius of the base 1. One end of the dividing strip 4 extends to the central mounting hole 3, and the other end is not in contact with the outer edge of the base 1. Figure 1 and Figure 2The length of the dividing strip is set at the extreme position to avoid interfering with the normal cutting effect of the circular cutting edge.

[0044] like Figure 5 As shown, the enlarged diameter cutting plate 6 includes a blade part 61 and a cutting edge part 62. The blade part 61 has a second positioning hole 63. The first positioning hole 5 and the second positioning hole 63 are connected by a positioning bolt 64. The thickness of the blade part 61 is the same as that of the dividing strip 4.

[0045] The cutting edge 62 is located on the side of the blade 61 opposite to the central mounting hole 3; the edge of the cutting edge 62 facing the blade 61 is coaxial with the central mounting hole 3. In this embodiment, a split-mounted expanding cutting plate and a circular cutting edge are used to expand the function and diameter of the cutting disc, making it more practical.

[0049] The bending plate 65 has two sets of notches 66, and a limiting block 67 and a limiting block 68 are fixedly installed on the dividing strip 4 within the notches 66; a telescopic component is fixedly installed on the blade 61, and the telescopic component moves up and down to be restricted between the limiting block 67 and the limiting block 68; after the expansion cutting plate is installed into the two sets of bending plates, the limiting blocks 67 and 68 are welded together, and the size of the notches is set to be larger than the size of the limiting blocks 67 and 68 to facilitate welding.

[0050] The corresponding diameter-expanding cutting plate 6 is provided with positions A and B on the base 1. At position A, the cutting edge 62 does not extend into a circular cutting edge 2; at position B, the cutting edge 62 extends into a circular cutting edge 2. Positions A and B correspond to the two states of the combined cutting disc to achieve the effect of changing the cutting function.

[0051] The telescopic component includes a cylindrical body 681 and a telescopic column 682. Cavities are provided at both ends of the cylindrical body 681, and the telescopic column 682 is installed thereon. A bearing spring 683 is installed between the telescopic column 682 and the inner wall of the cavity. One end of the bearing spring 683 is fixedly connected to the telescopic column 682, and the other end is fixedly connected to the inner wall of the cylindrical body 681. The telescopic column moves between a limiting block 1 and a limiting block 2. At both positions, the telescopic column is abutted by either limiting block 1 or limiting block 2. When the diameter-expanding cutting plate moves, the bearing spring keeps the end of the telescopic column abutting against the corresponding dividing strip. The telescopic component controls the moving distance of the diameter-expanding cutting plate, enabling rapid movement from the bottom of limiting block 2 to the bottom of limiting block 1, completing rapid positioning of the two positioning holes 1 and 2.
