Consequently, the demand for automated carbon rod cutting equipment is increasing. Currently, cutting equipment for square carbon rods into round ones mostly uses manual feeding, resulting in low cutting efficiency and poor precision.

[0014] The axes of the moving path, the cutting cavity, and the auxiliary clamping and conveying assembly are aligned.

[0015] In some embodiments of this application, the pushing part includes a pushing drive component, a pushing guide component, a pushing execution component, and a material storage component;

[0016] The storage component is used to store materials;

[0017] The push drive component drives the push execution component to move along the push guide component until the push execution component extends into the storage component to push the target material to the positioning component.

[0018] In some embodiments of this application, the positioning component includes a positioning plate adjustment component, a positioning plate guide component, a positioning plate, and an auxiliary positioning plate. The positioning plate adjustment component drives the positioning plate to move along the positioning plate guide component.

The positioning component positions the target material and finely adjusts the axial direction of the target material so that the axial direction of the target material, the pushing direction of the pusher, the axial direction of the clamping component, and the axial direction of the cutting component coincide. This allows the pusher to push the target material into the moving path formed in the clamping component. The pusher then pushes the target material along the moving path to the end, where it moves into the cutting cavity formed in the cutting component. The cutting component rotates to process the target material. During the processing, the target material is fed by the pusher and the rotation of the target material is limited by the clamping component.

[0100] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0101] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 9 As shown, a rotary cutting device is disclosed, comprising a pushing part 100, a feeding part 200, and a cutting part 300.

[0102] The pusher section 100 is used to receive multiple materials.

[0103] To achieve centralized placement of materials, the pusher 100 includes a storage component 140. The storage component 140 is used to store materials.

[0104] The material is a cylindrical material with a rectangular cross-section. Within the storage component 140, multiple cylindrical materials with rectangular cross-sections are arranged in the same direction.

[0105] The pushing section 100 also includes a pushing execution component 130. The pushing execution component 130 pushes the material from the storage section 140 into the feeding section 200.

[0106] Specifically, the pushing section 100 pushes only one target material at the feeding section 200.

[0107] like Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the feeding unit 200 includes a positioning component 210 and a pushing component 220. Since the materials in the storage component 140 are all placed in the same direction, and the direction in which the materials are placed in the storage component 140 is consistent with the direction in which the feeding unit 200 pushes the materials, the direction in which the feeding unit 200 pushes the target material 700 is consistent with the axial direction of the target material 700.

[0108] The pusher 100 pushes the target material 700 to the positioning component 210, the positioning component 210 finely adjusts the axis of the target material 700, and the pusher 220 pushes the target material 700 to the cutting section 300 in the same direction as the axis of the target material 700 for cutting.

[0109] The axial direction of the target material 700, the pushing direction of the pushing component 220, and the cutting axis of the cutting part 300 must be set to coincide.

[0110] The pusher component 220 pushes the target material 700 to the cutting section 300, and the cutting section 300 rotates to cut the target material 700.

[0111] The cutting section 300 includes a cutting assembly 310 and a clamping assembly 320.

[0112] A moving path 321 is formed within the clamping assembly 320 along its axis. The pushing assembly 220 pushes the target material 700 to the clamping assembly 320 and pushes the target material 700 to move along the moving path 321 until the end of the target material 700 extends out of the moving path 321, until the end of the target material 700 is pushed to the cutting assembly 310.

[0113] A cutting cavity 311 is formed within the cutting assembly 310 along its axial direction. The pushing assembly 220 moves the target material 700 along the moving path 321 until the end of the target material 700 enters the cutting cavity 311. The moving path 321 can limit the rotation of the target material 700 relative to it. With the end of the target material 700 entering the cutting cavity 311, the cutting assembly 310 rotates to cut the target material 700. The pushing assembly 220 continuously pushes the target material 700 along the moving path 321 and the cutting cavity 311, thereby achieving the cutting of the target material 700 along its axial direction.

[0114] As the pushing component 220 continuously pushes the target material 700 along the moving path 321, the front end of the target material 700 first extends into the moving path 321 and then moves out of the moving path 321. When the rear end of the target material 700 approaches the exit of the moving path 321, the cutting part 300 is also equipped with an auxiliary clamping and conveying component 400. The auxiliary clamping and conveying component 400 clamps the front end of the target material 700 and pulls the target material 700 to continue moving through the moving path 321 and the cutting cavity 311 until the rear end of the target material 700 also moves out of the moving path 321 and the cutting cavity 311, thereby completing the cutting and processing of the target material 700.

[0115] like Figure 10 As shown, the push component 220 includes a push driving component 221, a push guiding component 222, a push execution component 223, and a push transmission component. The push driving component 221 drives the push execution component 223 to move along the push guiding component 222.

[0116] Specifically, the push drive component 221 can be a third motor.

[0117] The push guide component 222 includes a push guide slider 2221 and a push guide rail 2222. The push guide slider 2221 can slide relative to the push guide rail 2222.

[0118] The push transmission assembly includes a push gear and a push rack 224. The push gear meshes with the push rack 224.

[0119] The output shaft of the third motor drives the push gear to rotate.

[0120] The push gear drives the push rack 224 to move.

[0121] The push execution component 223 is connected to the push rack 224. The push rack 224 drives the push execution component 223 to move, thereby pushing the target material 700 to move.

[0122] The direction in which the push rack 224 drives the push execution component 223 to move is the axial direction of the target material 700. The push rack 224 drives the push execution component 223 to move the target material 700 along the axial direction of the target material 700.

[0123] The clamping assembly 320 is located on the side of the cutting assembly 310 near the feeding section 200.

[0124] like Figure 11 As shown, the auxiliary clamping and conveying assembly 400 is located on the side of the cutting assembly 310 away from the feeding section 200.

[0125] That is, the clamping assembly 320 and the auxiliary clamping and conveying assembly 400 are respectively arranged on both sides of the cutting assembly 310.

[0126] The end of the push component 220 pushes the target material 700 through the clamping component 320 to the cutting component 310. The end of the push component 220 pushes the target material 700 through the cutting component 310 to the auxiliary clamping and conveying component 400. The auxiliary clamping and conveying component 400 is configured to clamp the target material 700 and drive the target material 700 to move along the cutting cavity 311 until both ends of the target material 700 are moved out of the cutting cavity 311. The axes of the moving path 321, the cutting cavity 311 and the auxiliary clamping and conveying component 400 are aligned.

[0127] The auxiliary clamping and conveying assembly 400 includes an auxiliary clamping moving drive component 410, an auxiliary clamping guide component 420, an auxiliary clamping drive component 430, an auxiliary clamping execution component, and an auxiliary clamping moving transmission component 450.

[0128] The auxiliary clamping drive component 430 drives the auxiliary clamping execution component to move along the direction from near the cutting component 310 to far away from the cutting component 310 via the auxiliary clamping guide component 420;

[0129] The auxiliary clamping drive component 430 drives the auxiliary clamping execution component to clamp the target material 700 or cancel the clamping of the target material 700.

[0130] Specifically, the auxiliary clamping drive component 430 can be a cylinder. The auxiliary clamping execution component includes a first clamping component 441 and a second clamping component 442. The cylinder drives the first clamping component 441 and the second clamping component 442 to move closer together to clamp the target material 700, and the cylinder drives the first clamping component 441 and the second clamping component 442 to move further apart to release the clamping of the target material 700.

[0131] A first clamping recess 4411 is formed on the side of the first clamping member 441 near the second clamping member 442, and a second clamping recess 4421 is formed on the side of the second clamping member 442 near the first clamping member 441. An auxiliary clamping drive member 430 drives the first clamping recess 4411 and the second clamping recess 4421 to move closer together to clamp the target material 700, or drives the first clamping recess 4411 and the second clamping recess 4421 to move further apart to release the target material 700.

[0132] The auxiliary clamping guide assembly 420 includes an auxiliary clamping slide rail 421 and two auxiliary clamping sliders 422, which can move relative to the auxiliary clamping slide rail 421 under the drive of a cylinder. The first clamping component 441 and the second clamping component 442 are respectively connected to the two auxiliary clamping sliders 422.

[0133] The auxiliary clamping moving drive component 410 drives the auxiliary clamping execution component 450 to move in a direction closer to or away from the cutting component 310. This enables the target material 700 to be moved closer to or away from the cutting component 310 for cutting processing.

[0134] Specifically, the auxiliary clamping movement drive component 410 includes a first motor, and the auxiliary clamping movement transmission component 450 includes an auxiliary clamping movement rack 451 and an auxiliary clamping movement gear 452. The output shaft of the first motor is coaxially connected to the auxiliary clamping movement gear 452, and the first motor drives the auxiliary clamping movement gear 452 to rotate. The auxiliary clamping movement rack 451 meshes with the auxiliary clamping movement gear 452. The auxiliary clamping movement rack 451 is connected to the auxiliary clamping execution component, thereby driving the movement of the auxiliary clamping execution component to move closer to or away from the cutting component 310.

[0135] The pusher section 100 also includes a push drive component 110 and a push guide component 120.

[0136] The drive component 110 drives the drive execution component 130 to move along the drive guide component 120 until the drive execution component 130 pushes the target material 700 to the positioning component 210.

[0137] The push actuator 130 can be made of a plate-shaped material. The edge of the push actuator 130 abuts against the side of the target material 700 and pushes the target material 700 to the feeding section 200 from the side of the target material 700.

[0138] The push guide component 120 includes a push guide slider 121 and a push guide slide rail 122. The push guide slider 121 can slide relative to the push guide slide rail 122.

[0139] Specifically, there are two push guide components 120. The two push guide components 120 are respectively arranged on both sides of the push execution component 130.

[0140] Two push guide sliders 121 are respectively connected to the lower parts of the two sides of the push execution component 130.

[0141] The guide rail 122 extends along the moving direction of the push actuator 130.

[0142] By pushing the guide slider 121 to move along the push guide slide rail 122, the push actuator 130 can be moved in the direction of the push guide slide rail 122.

[0143] The drive component 110 can drive the actuation component 130 to move along the guide rail 122. The drive component 110 may be a cylinder.

[0144] The rotary cutting device also includes a frame 500. A push guide rail 122 extends and is mounted on the frame 500.

[0145] When the actuator 130 pushes the target material 700 to the positioning component 210, the positioning component 210 makes a fine adjustment to the target material 700.

[0146] Positioning component 210, positioning plate adjustment component, positioning plate guide component, and positioning plate 211.

[0147] The positioning plate guide assembly is inclined along its height. The positioning plate guide assembly gradually increases in height from near the pusher section 100 to far away from the pusher section 100.

[0148] Specifically, the positioning plate guide assembly includes a positioning plate guide rail 212 and a positioning plate guide slider 213. The positioning plate guide rail 212 is inclined along the aforementioned inclined direction. The positioning plate guide slider 213 slides inclined along the direction of the positioning plate guide rail 212.

[0149] The positioning plate 211 is connected to the positioning plate guide slider 213, and the positioning plate 211 moves with the positioning plate guide slider 213. This allows for adjustment of the height of the positioning plate 211 and its radial movement relative to the target material 700. Furthermore, it adjusts the height of the axis of the target material 700 placed on the positioning plate 211, as well as the radial position of the target material 700 relative to the cutting assembly 310.

[0150] The positioning plate adjustment assembly includes a set screw 214 and a set screw hole provided on the frame 500. The set screw 214 is threadedly connected to the set screw hole, and the connection direction of the set screw 214 and the set screw hole extends in the same direction as the positioning plate guide slider 213. The upper end of the set screw 214 abuts against the positioning plate 211.

[0151] By rotating the set screw 214, the positioning plate 211 is pushed, which in turn drives the positioning plate guide slider 213 to move relative to the positioning plate guide slide rail 212, thereby realizing the movement of the positioning plate 211.

[0152] In some embodiments of this application, the positioning plate adjustment assembly further includes an auxiliary positioning plate 215, with the edge of the positioning plate 211 adjacent to the edge of the auxiliary positioning plate 215. The positioning plate 211 is movable relative to the auxiliary positioning plate 215.

[0153] The pusher unit 100 moves the target material 700 to the adjacent position of the positioning plate 211 and the auxiliary positioning plate 215. One side of the target material 700 abuts against the side of the positioning plate 211. The target material 700 is supported by the auxiliary positioning plate 215. By adjusting the relative position of the positioning plate 211 and the auxiliary positioning plate 215, the axis of the target material 700 is adjusted to coincide with the axis of the cutting cavity 311, thereby ensuring subsequent cutting accuracy.

[0154] Specifically, the clamping assembly 320 includes a plurality of first jaws 322, which are arranged circumferentially around the moving path 321. The plurality of first jaws 322 surround the moving path 321. The plurality of first jaws 322 can be relatively close together or relatively far apart. According to the size of the target material 700, the size of the moving path 321 formed by the plurality of first jaws 322 is adjusted, thereby enabling the target material 700 to move along the moving path 321, and the moving path 321 to limit the rotation of the target material 700.

[0155] The movement principle of multiple first jaws 322 moving synchronously closer or farther apart is the same as that of a four-jaw chuck.

[0156] like Figure 5As shown, the cutting assembly 310 includes multiple second jaws 312. A cutting component 313 is disposed on the side of each second jaw 312 near the axis of the cutting cavity 311. The multiple second jaws 312 are arranged circumferentially around the cutting cavity 311, forming the cutting cavity 311. The multiple second jaws 312 can be relatively close or relatively far apart to adjust the distance between the multiple cutting components 313 and the axis of the cutting cavity to the target cutting size of the target material 700.

[0157] Multiple cutting components 313 mounted on multiple second jaws 312 cut the target material 700 by rotating. In order to achieve the rotation of the multiple second jaws 312, the cutting assembly 310 also includes a cutting drive component 314 and a cutting transmission component. The cutting drive component 314 drives the multiple second jaws 312 to rotate through the cutting transmission component.

[0158] Specifically, the cutting drive component 314 includes a second motor. The cutting transmission assembly includes a synchronous belt 315, a first synchronous pulley 316, and a second synchronous pulley 317. The output shaft of the second motor rotates with the first synchronous pulley 316, and the rotation is transmitted to the second synchronous pulley 317 via the synchronous belt 315. The second synchronous pulley 317 drives multiple second jaws 312 to rotate, thereby achieving rotary cutting of the target material 700.

[0159] In some other embodiments of this application, a guide section 600 is also included. The guide section 600 is disposed below the auxiliary clamping and conveying assembly 400. The processed target material 700 falls onto the guide section 600 after being released from the auxiliary clamping and conveying assembly 400.

[0160] The guide section 600 can be tilted to transport the target material 700. That is, the target material 700 can roll along the tilted guide section 600 to the material collection mechanism.

[0161] In some other embodiments of this application, in order to facilitate the maintenance and adjustment of the cutting component 313, it is necessary to adjust the distance between the cutting component 310 and the clamping component 320. Therefore, a sliding part 510 is provided on the frame 500, and the clamping component 320 is slidably connected to the frame 500 through the sliding part 510 to move closer to or further away from the cutting component 310.

[0162] Using the above method, cylindrical materials with a rectangular cross-section can be automatically cut into cylindrical materials with a circular cross-section.

[0163] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0164] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0165] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
