[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] This application provides a feeding and cutting mechanism. Specifically, as shown in the embodiments below... Figures 1 to 4 As shown, the feeding and cutting mechanism 10 includes a cutter assembly 100, a first rotation drive 200, a first cam 300, and a connecting rod assembly 400.

[0060] like Figure 2 As shown, there are two sets of cutter assemblies 100. The two sets of cutter assemblies 100 are respectively arranged on both sides of the conveying direction (X direction) of the material to be cut, so as to cut both sides of the material to be cut.

[0061] like Figure 1 As shown, the first rotation drive 200 is mounted on the machine base 101. The first rotation drive 200 can be a motor, such as a servo motor. Of course, other rotation drive components can also be selected. Figure 1 As shown, the drive end of the first rotation drive 200 is connected to a rotating shaft 210. The rotating shaft 210 is located below the cutter assembly 100, so as to drive the first cam 300 through the rotating shaft 210 to press down the cutter 140 of the cutter assembly 100 to achieve cutting. Figure 2 As shown, the rotating shaft 210 is set along a horizontal direction (i.e., the Y direction) that is perpendicular to the transmission direction (X direction).

[0062] like Figure 2 and Figure 3 As shown, the first cam 300 is mounted on the rotating shaft 210. Figure 2 As shown, since there are two sets of cutter assemblies 100, there are also two first cams 300, with one first cam 300 corresponding to each set of cutter assemblies 100.

[0063] like Figures 2 to 4 As shown, the connecting rod assembly 400 is mounted on the machine base 101 and positioned on one side of the rotating shaft 210 along the Y direction. Figure 3 and Figure 4 As shown, the connecting rod assembly 400 includes a V-shaped connecting rod 410 and a mounting base 420. The mounting base 420 is fixedly mounted on the machine base 101. The opening of the V-shaped connecting rod 410 faces the rotating shaft 210. The middle position of the V-shaped connecting rod 410 is rotatably connected to the mounting base 420, the upper end of the V-shaped connecting rod 410 is rotatably connected to the cutter assembly 100 through a first connecting member 411, and the lower end of the V-shaped connecting rod 410 is provided with a second connecting member 412. The second connecting member 412 is used to abut against the periphery of the first cam 300. Specifically, as shown... Figure 8 As shown in Figure a, when the convex portion 300a of the first cam 300 rotates downward, the convex portion abuts against the second connecting member 412, thereby causing the convex portion of the cam to press the V-shaped connecting rod 410 downward. The V-shaped connecting rod 410 rotates around the mounting base 420, driving the cutter assembly 100 to move downward, thus realizing the cutting operation. Since the V-shaped connecting rod 410 and the cutter assembly 100 are rotatably connected through the first connecting member 411, the rotation of the V-shaped connecting rod 410 can be converted into the linear movement of the cutter assembly 100.

[0064] like Figure 8 As shown in Figure b, when the protrusion 300a of the first cam 300 rotates to the position separated from the second connecting member 412, the cutter assembly 100 can be reset upwards under the action of the spring (first elastic member 150) and wait for the next cut. Of course, the cutter assembly 100 can also adopt other reset methods. For example, when the protrusion 300a of the first cam 300 rotates to the upward position, the cutter assembly 100 can be reset by pushing the protrusion 300a of the first cam 300 upwards. This is not limited here.

[0065] The aforementioned feeding and cutting mechanism 10 achieves downward cutting of the cutter assembly 100 through the cooperation of the first cam 300 and the connecting rod assembly 400, thereby efficiently cutting the material to be cut. The connecting rod assembly 400 includes a V-shaped connecting rod 410 and a mounting base 420. When the protrusion 300a of the first cam 300 rotates downward, the protrusion abuts against the second connecting member 412. The first cam 300 pushes the V-shaped connecting rod 410 to rotate around the mounting base 420, and the V-shaped connecting rod 410 drives the cutter assembly 100 to press down for cutting. This design, by using the V-shaped connecting rod 410, converts the rotation of the first cam 300 into linear movement of the cutter assembly 100, resulting in high cutting efficiency and good stability.

[0066] In the embodiments of this application, such as Figure 4As shown, in one embodiment, both the first connecting member 411 and the second connecting member 412 are cam bearing followers. Cam bearing followers are common parts in the mechanical field, and will not be described in detail here. The V-shaped connecting rod 410 is rotatably connected to the cutter assembly 100 through the first connecting member 411 (cam bearing follower), which can realize the conversion of the rotation of the V-shaped connecting rod 410 into the linear movement of the cutter assembly 100, that is, the conversion of the rotation of the first cam 300 into the linear movement of the cutter assembly 100. The V-shaped connecting rod 410 abuts against the first cam 300 through the second connecting member 412 (cam bearing follower). Since the outer ring roller of the cam bearing follower is rotatable, rolling friction is formed between the second connecting member 412 and the first cam 300, avoiding wear on the first cam 300.

[0067] Specifically, in one embodiment, such as Figure 6 As shown, the lower end of the cutter assembly 100 is provided with a strip-shaped hole 111, which extends along the transmission direction (X direction). The first connecting member 411 is a cam bearing follower, such as... Figure 7 As shown, a cam bearing follower typically includes a roller 4111 and a bolt 4112. (Combined) Figure 6 and Figure 7 The roller 4111 of the cam bearing follower is inserted into the strip hole 111 at the lower end of the cutter assembly 100, and the bolt 4112 of the cam bearing follower is connected to the upper end of the V-shaped connecting rod 410, thereby realizing the rotational connection between the V-shaped connecting rod 410 and the cutter assembly 100.

[0068] In one embodiment, such as Figure 9 As shown, the cutter assembly 100 includes a cutter slide bar 110, a mounting block 120, a mounting rod 130, and a cutter 140. Figure 1 As shown, a slide 500 is provided on the machine base 101, and the slide 500 is fixedly mounted on the machine base 101. The slide 500 is positioned above the rotating shaft 210 and the first cam 300. The cutter slide rod 110 is slidably mounted on the slide 500. It can be understood that the slide 500 must have a sliding hole for accommodating the insertion of the cutter slide rod 110. The cutter slide rod 110 is slidably inserted into the slide 500, with its upper and lower ends exposed. Figure 9 As shown, the mounting block 120 is positioned at the top of the cutter slide bar 110, in conjunction with... Figure 3 and Figure 9 As shown, the bottom end of the cutter slide bar 110 is rotatably connected to the V-shaped connecting rod 410 via the first connecting member 411. Figure 9 As shown, the mounting rod 130 is arranged in a horizontal direction (i.e., the Y direction) perpendicular to the transmission direction (X direction). One end of the mounting rod 130 is connected to the mounting block 120, and the other end of the mounting rod 130 is provided with a cutter 140.

[0069] The cooperation between the cutter slide bar 110 and the slide block 500 can improve the stability of the cutting assembly 100 in raising and lowering. The cutter slide bar 110 and the slide block 500 can achieve precise cooperation, so that the cutting size is accurate and the cutting surface is smooth, uniform and burr-free, thus ensuring the cutting quality of the product.

[0070] In one embodiment, in order to make the cutting position of the cutter 140 adjustable, such as Figure 9 As shown, a socket 121 can be provided on the mounting block 120, and the mounting rod 130 is inserted into the socket 121. The socket 121 is arranged along the Y direction, so that the position of the mounting block 120 can be adjusted along the Y direction, and thus the position of the cutter 140 on the mounting block 120 can also be adjusted along the Y direction. Furthermore, locking holes 122 are provided on both sides of the mounting block 120 along the transmission direction (X direction), and the locking holes 122 communicate with the socket 121. A locking screw (not shown in the figure) is provided in the locking hole 122, and the locking screw is threaded into the locking hole 122. The locking screw extends into the socket 121 and presses against the mounting rod 130 in the socket 121, thereby fixing the mounting rod 130 and the cutter 140. The position of the mounting rod 130 and the cutter 140 can be adjusted along the X direction by turning the locking screw. The above structural design allows the cutter 140 to be adjusted in the X and Y directions, that is, in terms of front-back, left-right and right-right adjustment, thereby improving the applicability of the feeding and cutting structure and enabling it to adapt to the cutting of materials of various specifications.

[0071] In one embodiment, such as Figure 1 As shown, the feeding and cutting mechanism 10 also includes a support assembly 600 and a second cam 700. (Reference) Figure 2 The support assembly 600 is used to support the material to be cut, and it is positioned between the two sets of cutter assemblies 100. During cutting, the material is supported by the support assembly 600. Figure 2 As shown, the second cam 700 is used to push the support assembly 600 upward during cutting, that is, to push the material on the support assembly 600 upward, thereby assisting the cutter assembly 100 in cutting smoothly. Figure 2 As shown, the second cam 700 is mounted on the rotating shaft 210 and positioned below the support assembly 600. Figure 10 As shown, when the second cam 700 rotates upward under the drive of the rotating shaft 210, the protrusion 700a of the second cam 700 can push the support assembly 600 to move upward to hold the material to be cut, making it easier to cut.

[0072] In one embodiment, such as Figure 4As shown, the support assembly 600 includes a support slide rod 610 and a support base 620. The support slide rod 610 is slidably mounted on the slide block 500. The support base 620 is located at the top of the support slide rod 610. The support assembly 600, including the support slide rod 610 and the support base 620, facilitates the cooperation between the support slide rod 610 and the slide block 500, thereby improving the stability of the support assembly 600 during lifting and lowering.

[0073] Combination Figure 4 and Figure 5 In one embodiment, the cutter slide bar 110 is provided with a first sliding hole 112 extending in the vertical direction (Z direction), and the support slide bar 610 is provided with a second sliding hole 611 extending in the vertical direction. A limiting strip 510 is inserted into the slide block 500, which is positioned in a horizontal direction (i.e., Y direction) perpendicular to the transmission direction (X direction). Figure 5 As shown, the limiting strip 510 passes through the first sliding hole 112 on the cutter slide bar 110 and the second sliding hole 611 on the support slide bar 610. Figure 5 As shown, a first elastic element 150 is provided in the first sliding hole 112. The upper end of the first elastic element 150 abuts against the top of the first sliding hole 112, and the lower end of the first elastic element 150 abuts against the limiting strip 510, thereby resetting the cutter 140 through the first elastic element 150. When the cutter assembly 100 moves downward under the action of the first cam 300 to cut, the first elastic element 150 is stretched downward. When the first cam 300 stops pulling down the cutter assembly 100, the cutter assembly 100 moves upward and resets under the elastic force of the first elastic element 150. Similarly, as... Figure 5 As shown, a second elastic element 630 is provided in the second sliding hole 611. The upper end of the second elastic element 630 abuts against the top of the second sliding hole 611, and the lower end of the second elastic element 630 abuts against the limiting strip 510, thereby resetting the support seat 620 through the second elastic element 630. When the support seat assembly 600 is pushed upward by the second cam 700, the second elastic element 630 is compressed. When the second cam 700 stops pushing the support seat assembly 600 upward, the support seat assembly 600 moves downward and resets under the elastic force of the second elastic element 630.

[0074] In one embodiment, such as Figure 1As shown, the feeding and cutting mechanism 10 also includes a feeding roller 810, a receiving roller 820, and a second rotation drive 830. The feeding roller 810 and the receiving roller 820 are rotatably mounted on the machine base 101, and are respectively located at both ends of the cutter assembly 100 along the transmission direction (X direction). The material to be cut is wound in a roll onto the feeding roller 810. In this embodiment, the material to be cut is a metal shielding component, and several metal shielding components are spaced apart on each roll. The feeding roller 810 continuously feeds the material, the cutter assembly 100 continuously cuts, and the receiving roller 820 rewinds the cut roll. Figure 1 As shown, the second rotation drive 830 is mounted on the machine base 101 and connected to the feeding wheel 810 and the receiving wheel 820. The second rotation drive 830 is used to drive the feeding wheel 810 and the receiving wheel 820 to rotate. In the embodiments of this application, as... Figure 1 As shown, the second rotation drive component 830 is a motor, which can be a stepper motor or other types of motors. Figure 1 As shown, the motor rotor is directly connected to the take-up reel 820, while the feed reel 810 is connected to the motor rotor via a synchronous belt 831 and a synchronous pulley. Of course, the motor can also be connected to the feed reel 810 and the take-up reel 820 in other ways.

[0075] The feeding roller 810 and the receiving roller 820 are positioned at both ends of the cutter assembly 100 along the X direction, so that the material between the feeding roller 810 and the receiving roller 820 can be easily cut by the cutter assembly 100.

[0076] In one embodiment, such as Figure 1 and Figure 2 As shown, the feeding and cutting mechanism 10 also includes material stop bars 910. The material stop bars 910 are disposed on the machine base 101 and on both sides in the transmission direction (X direction). The material stop bars 910 are used to limit the material to be cut, precisely confining the material between the two cutting blade assemblies 100 for precise cutting. Figure 2 As shown, a flow channel is formed between the two material baffles 910 for material to pass through. In this embodiment of the application, as... Figure 2 As shown, the material baffle 910 is provided with a strip-shaped mounting hole 911 extending in a horizontal direction (Y direction) perpendicular to the conveying direction (X direction). The width between the material baffles 910 can be adjusted through the strip-shaped mounting hole 911, that is, the width of the flow channel can be adjusted to accommodate materials of different sizes and improve the applicability of the feeding and cutting mechanism 10.

[0077] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
