DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are some, but not all, of the embodiments of the present utility model.

[0034] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] Please refer to the attached Figure 1 - attached Figure 2 , a cutter wheel mechanism of the present invention includes a driving component 1, a cutter wheel component 2, and a braking component 3. The driving component 1 includes a driven assembly and a rotating shaft 12, and the driven assembly is drivingly connected to the rotating shaft 12; the cutter wheel component 2 is fixedly connected to the rotating shaft 12; the braking component 3 includes symmetrically arranged hydraulic locking discs 31, and the hydraulic locking discs 31 are respectively connected to both ends of the rotating shaft 12, and the hydraulic locking discs 31 are used to brake the rotating shaft 12. The hydraulic locking disc 31 is provided with an oil injection port 32.

[0037] Among them, the driving component 1 is used to drive the cutter wheel component 2 to rotate by a required angle; specifically, the driven assembly drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the cutter wheel component 2 to rotate, thereby adjusting the cutter wheel 24 to a corresponding angle; among them, the driven assembly can be driven by an existing motor.

[0038] The cutter wheel component 2 is used to process products, and the cutter wheel component 2 is connected to the rotating shaft 12 to realize automatic adjustment of the angle of the cutter wheel 24.

[0039] The braking component 3 is used to brake the cutter wheel component 2 to ensure that the cutter wheel component 2 is fixed at the adjusted angular position and ensure the stability of the cutter wheel component 2 after angle adjustment.

[0040] In the cutter wheel mechanism of this embodiment, the action process of the automatic angle adjustment of the cutter wheel mechanism is as follows: start the driving component 1, the driven assembly drives the rotating shaft 12 to rotate, and since the rotating shaft 12 is fixedly connected to the cutter wheel component 2, the rotating shaft 12 drives the cutter wheel component 2 to rotate a certain angle. After the angle rotation is completed, oil is poured into the hydraulic locking disc 31 from the oil injection port 32, so that the hydraulic locking disc 31 expands, thereby playing a role in braking the rotating shaft 12, controlling the rotating shaft 12 to stop moving, and keeping the cutter wheel component 2 at the position after angle adjustment, realizing the function of automatically adjusting the angle of the cutter wheel 24.

[0041] Operating in the above manner can save labor, effectively improve the degree of automation, and the operation time is less, thereby improving the production efficiency of products.

[0042] In this structure, the automatic angle adjustment can avoid the errors of manual angle adjustment, correspondingly ensure the accuracy of angle adjustment, and effectively guarantee the uniformity of product quality. Moreover, the swing angle of the cutter wheel component can be adjusted steplessly, without any angle limitation, effectively improving the flexibility of angle swing. In addition, the overall design of this structure is simple, the improvement cost is low, the production cost can be correspondingly reduced, the economic benefit can be improved, and it is also convenient for later maintenance.

[0043] In some embodiments, please refer to the attached Figure 2 , the driven assembly includes a chain and a driven sprocket 111. The chain is connected to the driven sprocket 111, and the driven sprocket 111 is drivingly connected to the rotating shaft 12.

[0044] With this setting, an existing motor can be used to drive the chain to rotate, thereby driving the driven sprocket 111 to rotate, and further driving the rotating shaft 12 to perform a rotating action. The overall drive structure design is reasonably distributed, the action rhythm is smooth, and the rhythm is strong. And the overall structure is simple, which is convenient for later maintenance and management.

[0045] Embodiment 2:

[0046] The difference between this embodiment and Embodiment 1 is that, please refer to Figure 3 , the cutter wheel component 2 of this embodiment includes a first base 21, a second base 22, a cutter wheel shaft 23 and a cutter wheel 24. The first base 21 is connected to the second base 22, and the cutter wheel 24 is connected to the second base 22 through the cutter wheel shaft 23. With this setting, by connecting the first base 21 to the rotating shaft 12, the overall stability of the cutter wheel component 2 is ensured, and through the connection layout between the cutter wheel 24, the cutter wheel shaft 23 and the second base 22, the stable and smooth operation of the cutter wheel 24 during the operation can be ensured, and the safety of the cutter wheel 24 during the operation can be ensured.

[0047] In some embodiments, please refer to Figures 4 - 5 , the rotating shaft 12 is provided with a keyway 121, a flat key 122 is arranged in the keyway 121, and the first base 21 and the rotating shaft 12 are connected through the flat key 122. By adopting the cooperation setting of the keyway 121 and the flat key 122, the rotating shaft 12 and the first base 21 are fixedly connected, which not only realizes the connection stability between the rotating shaft 12 and the first base 21, but also facilitates the disassembly and assembly of the rotating shaft 12 and the first base 21, making the operation easy and convenient.

[0048] In some embodiments, please refer to Figure 6, the cutter wheel component 2 further includes an elastic component 25, and the elastic component 25 is connected between the first base 21 and the second base 22. Through the arrangement of the elastic component 25, when the cutter wheel is in the operation process, it can achieve the springback of the cutter wheel 24 when being pressed, realizing the flexibility of the cutter wheel 24, avoiding a series of problems such as fracture, deformation or cracks of the cutter wheel 24, effectively protecting the service life of the cutter wheel 24, and improving the durability of the cutter wheel 24. In addition, due to the combination of the elastic component and the cutter wheel, the role of the cutter wheel with a flexible function can ensure the smoothness of the product. The flexible characteristic can adapt to materials with irregular shapes and can avoid damage to the surface of the materials.

[0049] Specifically, the first base 21 is provided with a groove 211 corresponding to the elastic component 25. The elastic component 25 includes a spring 251 and a screw 252. The spring 251 is arranged in the groove 211, and the screw 252 penetrates through the second base 22 and is connected to the first base 21 through the spring 251. Preferably, the spring 251 protrudes from the groove 211, and the protruding area of the spring 251 forms a buffer gap 26 between the first base 21 and the second base 22.

[0050] By embedding the spring 251 into the groove 211, the overall structure is relatively compact, ensuring the connection stability between the first base 21 and the second base 22. And by setting the spring 251 to protrude from the groove 211, that is, the second base 22 is in contact with the spring 251. When the cutter wheel 24 is pressed, the second base 22 moves to a certain extent in the buffer gap 26, providing time and space for the spring 251 to buffer the external pressure, avoiding problems such as fracture, deformation or cracks caused by the cutter wheel 24's strong resistance. After the external force is removed, it can also ensure the springback of the cutter wheel 24, avoiding the inaccurate angle of the cutter wheel 24 and effectively ensuring the machining accuracy of the cutter wheel 24.

[0051] In addition, please refer to Figure 7 , the cutter wheel mechanism further includes a mounting plate 4 and a roller bearing 5, and the roller bearing 5 is connected between the mounting plate 4 and the rotating shaft 12. The chain can pass through the mounting plate 4 and is drivingly connected to the driven chain. Through this setting, it can ensure the independent operation of the mounting plate 4 and the driving component 1. The mounting plate 4 can ensure the installation stability of the overall cutter wheel mechanism and can also ensure the stable rotation of the cutter wheel component 2 at the required angle. At the same time, it is convenient for the installation operation of the cutter wheel mechanism.
