Description

Technical Field

[0001] This utility model relates to the field of brush cutting technology, specifically to an integrated blade head. Background Technology

[0002] In brush-making equipment, the structural design and motion characteristics of the cutter head directly affect the quality and efficiency of brush bristle cutting. Currently, mainstream equipment generally adopts a fixed cutter head arrangement, in which multiple blades are arranged in parallel along the periphery of the mounting plate 2 with the same extension direction. They perform unidirectional continuous cutting of the brush bristles by synchronous rotation. However, when the blades arranged in the same direction cut into the brush bristles, the force direction of each blade is highly consistent, which causes the cutting reaction force to be superimposed in the rotation plane of the mounting plate 2. This can easily cause equipment vibration and abnormal wear of the transmission mechanism, thereby reducing the stability of the cutting action and affecting the cutting effect of the brush bristles.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an integrated cutter head to solve the technical problem in the related technology that when the mounting discs 2 arranged in the same direction cut into the bristles, the cutting reaction force is easily superimposed in the rotation plane of the mounting disc 2 because the force direction of each blade is the same, which affects the cutting effect on the bristles.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: An integrated cutter head is provided, comprising: a bushing extending along a first preset direction; a mounting plate fixedly sleeved on the bushing; a first cutter head extending along a second preset direction and disposed on the mounting plate; and a second cutter head extending along a third preset direction and disposed on the mounting plate. The first cutter head and the second cutter head are spaced apart along the periphery of the mounting plate, and a preset angle is provided between the extending directions of the first cutter head and the extending directions of the second cutter head, wherein the preset angle is greater than 0° and less than 90°.

[0006] Furthermore, the integrated cutter head also includes a cutter head mounting assembly, which is disposed on the mounting plate 2. The cutter head mounting assembly has a first mounting part and a second mounting part. The first cutter head is disposed on the first mounting part, and the second cutter head is disposed on the second mounting part. The first mounting part extends along the extension direction of the first cutter head, and the second mounting part extends along the extension direction of the second cutter head. The first mounting part and the second mounting part are spaced apart along the periphery of the mounting plate 2.

[0007] Furthermore, the cutter head mounting assembly includes: a first mounting block extending along the extension direction of the first cutter head, the first mounting block being mounted on the mounting disc 2 and protruding from the mounting disc 2, and the first cutter head being mounted on the first mounting block; and a second mounting block extending along the extension direction of the second cutter head, the second mounting block being mounted on the mounting disc 2 and protruding from the mounting disc 2, and the second cutter head being mounted on the second mounting block.

[0008] Furthermore, the cutter head mounting assembly also includes: at least two first cutters, at least two second cutters, with each first cutter head and each second cutter head arranged intersecting along the periphery of the mounting disc 2; at least two first mounting blocks, each first mounting block corresponding to each first cutter head; and at least two second mounting blocks, each second mounting block corresponding to each second cutter head.

[0009] Furthermore, the area of ​​the first end face of the first mounting block is greater than the area of ​​the opposite end face of the first end face on the first mounting block; the area of ​​the second end face of the second mounting block is greater than the area of ​​the opposite end face of the second end face on the second mounting block; the second end face of the second mounting block and the first end face of the first mounting block are spaced apart along the periphery of the mounting plate 2.

[0010] Furthermore, the integrated cutter head also includes: a fixing hole is provided on the bushing, and the fixing hole extends in the radial direction of the bushing.

[0011] Beneficial effects:

[0012] 1. The bushing extends along a first preset direction and connects to the drive shaft. The mounting plate is fixedly sleeved on the bushing to form a power transmission base. This structure ensures that the rotational power is efficiently transmitted to multiple first cutters 8 and multiple second cutters 9 through the rigid connection between the bushing and the mounting plate, reducing vibration caused by deviation of the power transmission path. At the same time, the first cutters and second cutters are spaced apart along the periphery of the mounting plate and have a preset angle in their extension direction, so that the timing and angle of the two cutters cutting into the bristles are different, dispersing the cutting reaction force and avoiding the superposition of loads when cutting in the same direction, which affects the cutting effect on the bristles.

[0013] 2. The first end face and the second end face are spaced apart along the periphery of the mounting plate 2 to avoid interference between the mounting blocks when the two cutter heads are working, and to ensure independent movement space for the staggered cutter heads; this design also makes it easier to reserve more heat dissipation gaps around the mounting plate 2, reducing the temperature rise effect of multiple first cutter heads 8 and multiple second cutter heads 9 during high-speed cutting.

[0014] 3. A radially extending fixing hole is provided on the bushing for circumferential locking with the drive shaft by bolts or pins; the fixing hole penetrates the bushing radially, allowing the connecting parts to bear pure shear loads and avoiding stress concentration problems caused by traditional axial fixing; at the same time, the radial fixing method simplifies the assembly process of the bushing and the drive shaft and ensures the coaxiality of power transmission.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] According to an embodiment of this utility model, an integrated cutter head is provided. Please refer to [link / reference]. Figures 1 to 2 It includes: a bushing 1 extending along a first preset direction; a mounting plate 2 fixedly sleeved on the bushing 1; a first cutter head 8 extending along a second preset direction and disposed on the mounting plate 2; and a second cutter head 9 extending along a third preset direction and disposed on the mounting plate 2. The first cutter head 8 and the second cutter head 9 are spaced apart along the periphery of the mounting plate 2, and a preset angle is provided between the extending direction of the first cutter head 8 and the extending direction of the second cutter head 9, wherein the preset angle is greater than 0° and less than 90°.

[0021] Specifically, the preferred angle is 15° to 45°.

[0022] By adopting the above technical solution, the bushing 1 extends along the first preset direction and is connected to the drive shaft, and the mounting plate 2 is fixedly sleeved on the bushing 1 to form a power transmission base; this structure ensures that the rotational power is efficiently transmitted to multiple first cutters 8 and multiple second cutters 9 through the rigid connection between the bushing 1 and the mounting plate 2, reducing vibration caused by deviation of the power transmission path; at the same time, the first cutters 8 and the second cutters 9 are spaced apart along the periphery of the mounting plate 2 and have a preset angle in their extension direction, so that the timing and angle of the two cutters cutting into the bristles are different, dispersing the cutting reaction force and avoiding the superposition of loads when cutting in the same direction, which affects the cutting effect on the bristles.

[0023] Please refer to Figure 1 and Figure 2 The integrated cutter head also includes a cutter head mounting assembly 3. The cutter head mounting assembly 3 is disposed on the mounting plate 2. The cutter head mounting assembly 3 has a first mounting part and a second mounting part. A first cutter head 8 is disposed on the first mounting part, and a second cutter head 9 is disposed on the second mounting part. The first mounting part extends along the extension direction of the first cutter head 8, and the second mounting part extends along the extension direction of the second cutter head 9. The first mounting part and the second mounting part are spaced apart along the periphery of the mounting plate 2.

[0024] By adopting the above technical solution, the first mounting part and the second mounting part of the cutter head mounting assembly 3 are independently arranged along the extension direction of the first cutter head 8 and the second cutter head 9, respectively, and are distributed at intervals along the periphery of the mounting plate 2. This design separates the mounting bases of the first cutter head 8 and the second cutter head 9, allowing the two cutters to independently bear the cutting load and avoiding stress concentration caused by sharing a mounting base. In addition, the extension direction of the first mounting part and the second mounting part is consistent with the extension direction of the corresponding cutter head, ensuring that the installation direction of the cutter head is precisely aligned with the cutting trajectory and improving cutting stability.

[0025] Please refer to Figure 1 and Figure 2 The cutter head mounting assembly 3 includes: a first mounting block 4, which extends along the extension direction of the first cutter head 8, is mounted on the mounting plate 2, and protrudes from the mounting plate 2, and the first cutter head 8 is mounted on the first mounting block 4; and a second mounting block 5, which extends along the extension direction of the second cutter head 9, is mounted on the mounting plate 2, and protrudes from the mounting plate 2, and the second cutter head 9 is mounted on the second mounting block 5.

[0026] By adopting the above technical solution, the first mounting block 4 and the second mounting block 5 protrude from the surface of the mounting disk 2 along the extension direction of the first cutter head 8 and the second cutter head 9, respectively, to form a cutter head support base; the spaced arrangement of the first mounting block 4 and the second mounting block 5 provides space for circumferential heat dissipation of the cutter head and reduces the heat accumulation effect during continuous operation.

[0027] Please refer to Figure 1 and Figure 2 The cutter head mounting assembly 3 further includes: at least two first cutter heads 8 and at least two second cutter heads 9, with each first cutter head 8 and each second cutter head 9 arranged intersecting along the periphery of the mounting plate 2; at least two first mounting blocks 4, each first mounting block 4 corresponding to each first cutter head 8; and at least two second mounting blocks 5, each second mounting block 5 corresponding to each second cutter head 9.

[0028] By adopting the above technical solution, multiple first cutter heads 8 and multiple second cutter heads 9 are arranged crosswise along the periphery of the mounting plate 2, and each cutter head is independently fixed by the corresponding first mounting block 4 and second mounting block 5. By arranging the cutter head groups crosswise, the cutting action point is dispersed along the circumference, further balancing the radial load distribution during rotary cutting.

[0029] Please refer to Figure 1 and Figure 2 The area of ​​the first end face 6 of the first mounting block 4 is greater than the area of ​​the opposite end face of the first end face 6 on the first mounting block 4; the area of ​​the second end face 7 of the second mounting block 5 is greater than the area of ​​the opposite end face of the second end face 7 on the second mounting block 5; the second end face 7 of the second mounting block 5 and the first end face 6 of the first mounting block 4 are spaced apart along the periphery of the mounting plate 2.

[0030] By adopting the above technical solution, the first end face 6 and the second end face 7 are spaced apart along the periphery of the mounting plate 2 to avoid interference between the mounting blocks when the two cutter heads are working, and to ensure the independent movement space of the staggered cutter heads. This design also makes it easier to reserve more heat dissipation gaps around the mounting plate 2, and reduce the temperature rise effect of multiple first cutter heads 8 and multiple second cutter heads 9 during high-speed cutting.

[0031] Please refer to Figure 1 and Figure 2 The integrated cutter head also includes: a fixing hole is provided on the bushing 1, and the fixing hole extends in the radial direction of the bushing 1.

[0032] By adopting the above technical solution, a radially extending fixing hole is opened on the bushing 1 for circumferential locking with the drive shaft by bolts or pins; the fixing hole penetrates the bushing 1 radially, so that the connecting parts bear pure shear loads and avoid the stress concentration problem caused by traditional axial fixing; at the same time, the radial fixing method simplifies the assembly process of the bushing 1 and the drive shaft and ensures the coaxiality of power transmission.

[0033] Working principle:

[0034] First, the bushing 1 is rigidly connected to the drive shaft along the first preset direction (usually the direction of the rotation axis), and circumferential locking is achieved through fixing holes (such as radial bolts) to ensure that power is efficiently transmitted to the mounting plate 2;

[0035] The mounting plate 2 is fixedly mounted on the bushing 1 and rotates synchronously with the bushing 1, driving the first cutter head 8, the second cutter head 9 and the cutter head mounting assembly 3 to make circular motion around the axis, forming a continuous cutting action.

[0036] The first cutter head 8 extends along a second preset direction (such as an inclination angle α), and the second cutter head 9 extends along a third preset direction (such as an inclination angle β), with the two extending directions forming a preset angle (such as 60°).

[0037] When the mounting plate 2 rotates, the first cutter head 8 and the second cutter head 9 contact the bristle bundle at different cutting angles in sequence, dispersing the cutting resistance and avoiding vibration caused by the superposition of forces on the blades in the same direction;

[0038] Multiple first cutter heads 8 and multiple second cutter heads 9 are arranged at intervals along the periphery of the mounting plate 2, so that the cutting action point is evenly distributed on the rotation plane of the mounting plate 2, balancing the radial load and reducing abnormal wear of the transmission mechanism.

[0039] The first mounting block 4 protrudes from the surface of the mounting plate 2 along the extension direction of the first cutter head 8, forming a cutter head support base and enhancing the bending stiffness of the first cutter head 8; similarly, the second mounting block 5 provides stable support for the second cutter head 9, preventing the cutter head from swaying due to the cantilever effect during high-speed cutting.

[0040] The first end face 6 and the second end face 7 are distributed at intervals along the circumference of the mounting plate 2. An airflow channel is formed between the first end face 6 and the second end face 7 to accelerate the dissipation of heat generated during the cutting process and prevent the material properties of multiple first cutter heads 8 and multiple second cutter heads 9 from degrading due to excessive temperature rise.

[0041] The radial fixing hole on bushing 1 allows the connecting parts (such as bolts) to bear pure shear loads, avoiding stress concentration caused by axial fixing and improving the connection reliability between bushing 1 and drive shaft.

[0042] The radial fixing method ensures the coaxiality of the bushing 1 and the drive shaft, reduces vibration caused by eccentric rotation, and ensures the accuracy of the cutting trajectory.
