[0038] like Figures 1-9 As shown, this embodiment provides a cutting device, which includes a base 1 and a cutting mechanism 2. The base 1 includes a pressure-bearing component, which includes a first pressure-bearing part 11 and a second pressure-bearing part 12. A cutting groove 13 is formed between the first pressure-bearing part 11 and the second pressure-bearing part 12. The cutting mechanism 2 includes a driving component 21, a pressing component and a cutting component 24. The pressing component includes a first pressing member 22 and a second pressing member 23. The driving component 21 can drive the pressing component to press against the pressure-bearing component. When the pressing component presses against the pressure-bearing component, the first pressing member 22 presses against the first pressure-bearing part 11, and the second pressing member 23 presses against the second pressure-bearing part 12. When the workpiece to be cut is clamped between the pressing component and the pressure component, the driving component 21 can drive the cutting component 24 to pass through the workpiece to be cut and extend into the cutting groove 13.

[0039] In this embodiment, the base 1 includes a pressure-bearing assembly, which includes a first pressure-bearing portion 11 and a second pressure-bearing portion 12. Since the workpiece to be cut is separated into a finished product and scrap material after cutting, the first pressure-bearing portion 11 and the second pressure-bearing portion 12 are used to support the finished product and scrap material, respectively, to improve the cutting effect. A cutting groove 13 is formed between the first pressure-bearing portion 11 and the second pressure-bearing portion 12, allowing the cutting assembly 24 to extend into the cutting groove 13 to cut the workpiece to be cut, thereby providing space for cutting and ensuring cutting accuracy. The cutting mechanism 2 includes a driving assembly 21, a pressing assembly and a cutting assembly 24. The pressing assembly includes a first pressing member 22 and a second pressing member 23. The driving assembly 21 can drive the pressing assembly to press against the pressure assembly. When the pressing assembly presses against the pressure assembly, the first pressing member 22 presses against the first pressure portion 11, and the second pressing member 23 presses against the second pressure portion 12, so that a part of the structure of the workpiece to be cut is clamped between the first pressing member 22 and the first pressure portion 11, and the other part of the workpiece to be cut is clamped between the second pressing member 23 and the second pressure portion 12. This not only ensures that the position of the workpiece to be cut is fixed and the cutting is more accurate, but also ensures that the workpiece to be cut is evenly stressed, so as to facilitate the cutting operation and achieve better cutting effect. When the workpiece to be cut is clamped between the pressing assembly and the pressure assembly, the driving assembly 21 can drive the cutting assembly 24 to pass through the workpiece to be cut and extend into the cutting groove 13, thereby cutting the workpiece to be cut into the desired shape. Through the above-mentioned arrangement, the cutting device of the present application can efficiently and conveniently realize the cutting operation of the tape waiting to be cut, and the cutting effect is better.

[0040] The specific structure of the cutting device is described below:

[0041] Specifically, if Figure 4-Figure 6 As shown, in this embodiment, the first pressure-bearing part 11 and the second pressure-bearing part 12 are both pressure-bearing blocks, and the two pressure-bearing blocks are provided with a pressure-bearing surface at one end facing the pressure component to support the piece to be cut. Moreover, the second pressure-bearing part 12 is arranged to extend along the circumference of the first pressure-bearing part 11, and a cutting groove 13 is formed between the second pressure-bearing part 11 to facilitate cutting multiple corners of the tape to be cut to fit the shape of the shielding cover. In other embodiments, the first pressure-bearing part 11 and the second pressure-bearing part 12 can adopt a plate-like structure. It can be understood that there are no excessive restrictions on the specific structure and setting method of the first pressure-bearing part 11 and the second pressure-bearing part 12, and they can be adjusted according to the cutting requirements of the finished product.

[0042] Specifically, if Figure 2-Figure 7 As shown, the driving assembly 21 includes a cutting driver 211 and a transmission member 212. The transmission member 212 is slidably connected to the base 1 and is connected to the cutting assembly 24. The output end of the cutting driver 211 is connected to the transmission member 212, which can drive the transmission member 212 to slide relative to the base 1 and drive the cutting assembly 24 to pass through the workpiece to be cut and extend into the cutting groove 13, thereby achieving efficient cutting of the workpiece to be cut without the need for manual operation by the operator, thereby improving the cutting efficiency and work quality.

[0043] More specifically, a first slide bar 14 is provided on the base 1, and the transmission member 212 is slidably connected to the first slide bar 14. This arrangement not only provides a precise sliding track for the transmission member 212, but also ensures the stability and accuracy of the transmission member 212 during movement.

[0044] More specifically, in this embodiment, two first slide bars 14 are provided, spaced apart on the base 1. The ends of the transmission member 212 are slidably connected to the two first slide bars 14, respectively. This ensures smooth operation of the transmission member 212 relative to the base 1 and prevents shaking or deviation of the transmission member 212 due to uneven force. In other embodiments, three or four first slide bars 14 are provided. The specific number of first slide bars 14 is not particularly limited, as long as it can achieve the aforementioned functions.

[0045] Specifically, if Figure 2-Figure 7As shown, in this embodiment, the cutting driver 211 includes a second sliding bar 2111, a driving bar 2112, and a transmission bar 2113. The second sliding bar 2111 is slidably connected to the base 1 and is connected to the transmission member 212. The driving bar 2112 is rotationally connected to the base 1. The two ends of the transmission bar 2113 are respectively rotationally connected to the second sliding bar 2111 and the driving bar 2112. When the driving bar 2112 rotates, the transmission bar 2113 drives the second sliding bar 2111 to slide relative to the base 1. When the second sliding bar 2111 slides, it drives the transmission member 212 and the cutting assembly 24 to move, thereby achieving the cutting operation of the workpiece to be cut. In the above process, through the rotation of the driving bar 2112 and the transmission of the transmission bar 2113, the second sliding bar 2111 can be accurately controlled, thereby ensuring the stability and efficiency of the cutting process. It should be noted that the drive rod 2112 can be rotated by manual operation of the operator, or the drive rod 2112 can be rotated by a motor to achieve the above function. No excessive restrictions are placed on the specific driving method of the drive rod 2112, as long as the above function can be achieved.

[0046] More specifically, in other embodiments, the cutting actuator 211 includes an electric cylinder, the output end of which is connected to the transmission member 212, capable of driving the transmission member 212 to slide relative to the base 1, thereby driving the cutting assembly 24 through the workpiece to be cut and extending into the cutting groove 13. It will be understood that the specific structure of the cutting actuator 211 is not limited, as long as it can achieve the above-mentioned functions.

[0047] Specifically, if Figure 2-Figure 8 As shown, the first pressing member 22 is slidably connected to the transmission member 212 and to the second pressing member 23. When the pressing assembly abuts against the pressure assembly, the transmission member 212 can slide relative to the pressing assembly. When the cutting driver 211 drives the transmission member 212 to move relative to the base 1, it drives the pressing assembly closer to the pressure assembly. When the pressing assembly abuts against the pressure assembly, that is, when the first pressing member 22 abuts against the first pressure portion 11 and the second pressing member 23 abuts against the second pressure portion 12, the workpiece to be cut is clamped between the pressing assembly and the pressure assembly, thereby achieving the fixing effect of the workpiece to be cut. When the cutting driver 211 further drives the transmission member 212 to move relative to the base 1, the pressing component is pressed against the pressure component and cannot continue to move relative to the base 1. At this time, the transmission member 212 will slide relative to the pressing component and drive the cutting component 24 to extend into the cutting groove 13 to achieve cutting of the workpiece to be cut, thereby ensuring the smooth progress of the cutting operation and preventing the pressing component from pressing against the pressure component and interfering with the continued movement of the transmission member 212 and the cutting component 24.

[0048] More specifically, in this embodiment, the first pressure member 22 includes a slider, and the transmission member 212 includes two transmission plates that are parallel to each other and spaced apart, and the two transmission plates are connected by a plurality of connecting rods. The transmission plate close to the cutting drive 211 is connected to the second slide bar 2111, and the transmission plate away from the cutting drive 211 is provided with a slide groove. The slider is slidably connected to the slide groove, and one end of the slider is provided with a limit plate. The limit plate is assembled between the two transmission plates and can abut against the open end of the slide groove, so that the slider is limited to the transmission plate and cannot be separated from the two transmission plates. The other end of the slider is configured to abut against the first pressure portion 11 to ensure that the tape waiting to be cut is clamped between the slider and the first pressure portion 11 to achieve fixation, thereby improving the cutting effect. In other embodiments, the first pressure member 22 is a slide bar that is slidably connected to the transmission member 212, that is, the specific structure of the first pressure member 22 is not limited, as long as it can achieve the above-mentioned functions.

[0049] More specifically, in this embodiment, the second pressure member 23 includes a pressure plate and a plurality of connecting rods, the plurality of connecting rods being parallel to each other and spaced apart on the pressure plate, one end of the connecting rod being connected to the pressure plate, and the other end being connected to the limit plate of the first pressure member 22. Furthermore, a through hole is provided on the pressure plate, through which the slider of the first pressure member 22 extends, and the other end of the slider is kept flush with the end of the pressure plate away from the connecting rod, so that when the other end of the slider abuts against the first pressure portion 11, the end of the pressure plate away from the connecting rod abuts against the second pressure portion 12, thereby ensuring that the first pressure member 22 and the second pressure member 23 can abut against the first pressure portion 11 and the second pressure portion 12 synchronously and in a one-to-one correspondence, thereby improving the cutting quality and effect. In other embodiments, the second pressure member 23 is a sliding rod connected to the first pressure member 22, that is, the specific structure of the second pressure member 23 is not limited, as long as it can achieve the above-mentioned functions.

[0050] Specifically, if Figures 1-8 As shown, the cutting mechanism 2 includes an elastic member 25, one end of which abuts against the transmission member 212, and the other end abuts against the first pressing member 22, so that the first pressing member 22 can abut against the first pressure portion 11 under the support of the elastic member 25, thereby stably clamping the workpiece to be cut between the first pressing member 22 and the first pressure portion 11. Moreover, since the second pressing member 23 is connected to the first pressing member 22, the second pressing member 23 will also abut against the second pressure portion 12 under the support of the elastic member 25, thereby achieving clamping of different parts of the workpiece to be cut, thereby improving the cutting effect and quality. Among them, the elastic member 25 is selected from a coil spring or an elastic rubber pad, and the specific structure of the elastic member 25 is not further limited here.

[0051] Specifically, if Figure 2 、 Figure 4 and Figure 8As shown, the transmission member 212 is provided with a limiting portion 2121 that slides with the first pressure member 22. The elastic member 25 is sleeved on the limiting portion 2121 to ensure that the elastic member 25 can maintain a stable position and shape when the transmission member 212 moves. One end of the elastic member 25 abuts the limiting portion 2121. As the transmission member 212 moves, the first pressure member 22 abuts against the first pressure portion 11 under the support of the elastic member 25, thereby stably clamping the workpiece to be cut between the first pressure member 22 and the first pressure portion 11. At the same time, because the second pressure member 23 is connected to the first pressure member 22, the second pressure member 23 also abuts against the second pressure portion 12 under the support of the elastic member 25, thereby achieving clamping of different parts of the workpiece to be cut.

[0052] More specifically, in this embodiment, the limiting portion 2121 is a limiting rod, and the elastic member 25 is a spring. The spring is sleeved on the limiting rod, one end of the spring abuts the limiting rod, and the other end abuts the first pressure member 22. When the pressure assembly abuts against the pressure-bearing assembly, the cutting driver 211 can drive the transmission member 212 to move. At this time, the transmission member 212 slides relative to the first pressure member 22 and the second pressure member 23, and drives the spring to compress and accumulate elastic potential energy, thereby through the supporting action of the spring, the first pressure member 22 and the second pressure member 23 are respectively firmly abutted against the first pressure-bearing portion 11 and the second pressure-bearing portion 12, ensuring that the workpiece to be cut will not move or shift under the clamping action between the pressure assembly and the pressure-bearing assembly, and then the cutting assembly 24 is driven to extend into the cutting groove 13 through the movement of the transmission member 212, thereby achieving stable and accurate cutting of the workpiece to be cut.

[0053] Specifically, if Figure 2-Figure 9 As shown, the cutting assembly 24 includes a plurality of cutters 241 connected in sequence. Two adjacent cutters 241 have a protrusion 2411 on one side and a slot 2412 on the other side that engages with the protrusion 2411 on the other side. The engagement of the protrusion 2411 with the slot 2412 effectively prevents the cutters 241 from falling off or becoming misaligned during the cutting process, thereby ensuring continuous and accurate cutting. Furthermore, the tight fit between the protrusion 2411 and the slot 2412 further enhances the connection strength between adjacent cutters 241, making the entire cutting assembly 24 more stable and reliable.

[0054] More specifically, in this embodiment, three cutters 241 are provided. These three cutters 241 are connected in sequence to form a cylindrical structure. The cylindrical structure is fixedly connected to the transmission member 212 via a jackscrew to ensure that the movement of the transmission member 212 can drive the cutting assembly 24 along with it. Furthermore, one end of the cutter 241 is tilted, forming an angle of 25° to 45° with the direction of movement of the cutting assembly 24. This allows the cutter 241 to break the surface resistance of the workpiece to be cut, thereby improving cutting efficiency and quality. In other embodiments, there may be five or six cutters 241. As long as the aforementioned functions can be achieved, the specific number of cutters 241 is not limited.

[0055] Specifically, if Figure 5-Figure 9 As shown, multiple cutters 241 are arranged around a penetration groove 2413, and a guide portion 221 is provided on the first pressure member 22, which is slidably penetrated in the penetration groove 2413. When the first pressure member 22 is against the first pressure-bearing portion 11, the transmission member 212 moves relative to the first pressure member 22 and drives the multiple cutters 241 to move toward the cutting groove 13. Through the above arrangement, the multiple cutters 241 can slide stably along the extension direction of the guide portion 221 to ensure that the cutting assembly 24 can move stably along the predetermined path during the cutting process, thereby improving the efficiency and accuracy of cutting.

[0056] Specifically, if Figure 2-Figure 6 As shown, a plurality of limiting members 15 are provided on the base 1, and the cutting mechanism 2 is limited between the plurality of limiting members 15, which can ensure that the cutting mechanism 2 maintains a stable limiting state during the cutting process, thereby improving the accuracy and stability of cutting.

[0057] More specifically, in this embodiment, the limiting member 15 is a limiting block, and two limiting blocks are provided, and the two limiting blocks are spaced apart on the base 1 to facilitate good limiting of the cutting mechanism 2 and facilitate the operator to assemble and use the cutting device.

[0058] The specific working process of the cutting device is described below:

[0059] First, the workpiece to be cut is placed on the pressure-bearing assembly. When the operator rotates the driving rod 2112, the transmission rod 2113 drives the second slide bar 2111 to slide relative to the base 1. The sliding of the second slide bar 2111 drives the transmission member 212 to slide relative to the base 1. The sliding of the transmission member 212 drives the cutting assembly 24 and the pressing assembly to move toward the pressure-bearing assembly. When the pressing assembly abuts against the pressure assembly, that is, the workpiece to be cut is clamped between the first pressing member 22 and the first pressure-bearing portion 11, and the second pressing member 23 and the second pressure-bearing portion 12 to achieve the limiting effect, the second slide bar 2111 continues to move relative to the base 1, causing the transmission member 212 to slide relative to the pressing assembly and drive the cutting assembly 24 to extend into the cutting groove 13, thereby completing the cutting operation of the workpiece to be cut. At the same time, the transmission member 212 slides relative to the pressing assembly, causing the elastic member 25 to contract and support the pressing assembly against the pressure assembly, thereby ensuring that the workpiece to be cut is evenly stressed, facilitating cutting. Moreover, through the supporting effect of the elastic member 25, the finished product of the workpiece to be cut can be clamped between the first pressing member 22 and the first pressure-bearing portion 11, while the edge waste is clamped between the second pressing member 23 and the second pressure-bearing portion 12, thereby ensuring the cutting effect. When the cutting operation is completed, the operator operates the drive rod 2112 to rotate to the initial position, so that the cutting assembly 24 can be withdrawn from the cutting groove 13 and the pressing assembly and the pressure assembly are separated from each other, thereby preparing for the next cutting operation.

[0060] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
