Detailed Implementation

[0018] Please refer to Figures 1-7 This embodiment is a cutting device 100 with automatic feeding function, which includes a cutting mechanism 1 for cutting the material strip, a feeding track 2 connected to the left and right sides of the cutting mechanism 1, and a feeding module 3 set on the feeding track 2 and driving the material strip to move forward.

[0019] Specifically, the cutting mechanism 1 includes a cutting die assembly 11, a cutting punch assembly 12 that is vertically opposite to and cooperates with the cutting die assembly 11 to perform the cutting action, and a lifting drive module 13 that drives the cutting punch assembly 12 to perform lifting action; the cutting die assembly 11 includes a positioning die 113, on which a first slide groove 111 for moving the feed belt forward is provided, and a plurality of dropping holes 112 are provided below the first slide groove 111; the cutting punch assembly 12 includes a punch plate 122 and a plurality of cutting blades 121 provided below the punch plate 122 and cooperating with the plurality of dropping holes 112.

[0020] The feeding track 2 is connected to the left and right sides of the cutting mechanism 1. The feeding track 2 is provided with a second slide groove 29 that mates with the first slide groove 111.

[0021] The feeding module 3 is set on the feeding track 2. The feeding module 3 includes a first rotary drive 31 and a drive disk 32 detachably connected to the output shaft end of the first rotary drive 31. A number of drive protrusions 33 are evenly spaced on the outer periphery of the drive disk 32.

[0022] Since the outer periphery of the drive disk 32 is arc-shaped, to facilitate the cooperation between the drive disk 32 and the feeding track 2, the feeding track 2 is provided with an arc-shaped clearance groove 25 above the edge of the second slide groove 29, which conforms to the outer periphery of the drive disk 22. A first clearance opening 26 for the drive protrusion 33 to extend into is provided directly below the arc-shaped clearance groove 25. A connector 300 is connected in the middle of the strip 200, and a first positioning hole 201 that mates with the drive protrusion 33 is provided on the edge of the strip 200. During cutting, the strip on the side of the connector 300 is cut off, and the cut-off position is as follows... Figure 7 At the position indicated by the dotted line, when the feeding module 3 drives the material belt forward, the driving protrusion 33 can extend into the first positioning hole 201 and conform to the shape of the first positioning hole 201. The lower end of the driving protrusion 33 extends into the first clearance opening 26. When the first rotary driving member 31 drives the driving disk 32, the driving protrusion 33 can drive the material belt to move forward, realizing the automatic feeding action.

[0023] A connecting block 35 is fixed to the output shaft end of the first rotary drive 31. The drive disk 32 is detachably mounted on the connecting block 35 by a number of first fasteners 34, thereby realizing the installation of the drive disk 32 and the first rotary drive 31. When changing the material belt 200, the size and spacing of the first positioning holes 201 on it may be different. At this time, the material feeding action can be realized by replacing the corresponding drive disk 32, which can adapt to different material belts.

[0024] In this embodiment, two feeding modules 3 are provided, one on the input side and the other on the output side of the feeding track 2, that is, the two feeding modules 3 are respectively located on the left and right sides of the cutting mechanism 1. The feeding module 3 on the input side of the feeding track 2 pushes the material strip before cutting forward, and the feeding module 3 on the output side of the feeding track 2 pulls the cut material strip forward. The two feeding modules 3 work together to realize the automatic feeding action of the material strip.

[0025] The input and output sides of the feeding track 2 are sequentially equipped with a first pressing component 21, a calibration component 22, and a first sensor 23. The first pressing component 21 is used to elastically press the material strip, the calibration component 22 is used to insert into the first positioning hole 201 to position and calibrate the material strip, and the first sensor 23 detects whether the material strip is in a horizontal state. If the material strip is bent or its vertical position is offset, the first sensor 23 will issue an alarm.

[0026] The first pressing assembly 21 includes a pressing base 211 and a pressing block 213 disposed on the pressing base 211 by a first elastic element 212. The pressing block 213 is elastically pressed against the edge of the material strip to prevent the vertical position of the material strip from shifting. The first elastic element 212 is used to make the pressing block 213 elastically pressed against the edge of the material strip, which also prevents the pressing block 213 from damaging the material strip. The feeding track 2 is provided with a first clearance hole 27 to avoid the pressing block 213.

[0027] The calibration component 22 includes a calibration seat 221 and a calibration element 223 disposed on the calibration seat 221 by a second elastic element 222. The lower end of the calibration element 223 can extend into the first positioning hole 201 to position and calibrate the material strip. The feeding track 2 is provided with a second clearance hole to avoid the calibration element 223.

[0028] A second pressing assembly 24 is also provided at the input end of the feeding track 2. The second pressing assembly 24 presses the material strip to ensure the cutting accuracy of the cutting mechanism 1. The second pressing assembly 24 includes a pressing seat 241, a support member 242 and a pressing member 243 disposed on the pressing seat 241. The pressing member 243 is disposed on the pressing seat 241 with adjustable vertical position. The pressing seat 241 is provided with an oblong hole for mounting the pressing member 243. The position of the pressing member 243 can be adjusted by adjusting its position at the oblong hole so as to adapt to material strips of different thicknesses.

[0029] The lifting drive module 13 includes a rotary drive component 131, a rotary component 132 driven by the rotary drive component 131 to rotate around a horizontal axis, and a cam 133 eccentrically mounted on the rotary component 132. A mounting bracket 134 is provided above the convex template 122. A connector 135 is rotatably mounted on the mounting bracket 134 via a first support shaft 137. The upper end of the connector 135 is provided with a movable groove 136 for the cam 133 to move.

[0030] The lower part of the convex template 122 is connected to the first positioning plate 124 via the elastic component 123. The first positioning plate 124 is provided with several third clearance holes to avoid the cutting blade 121. The lower part of the first positioning plate 124 is provided with several positioning pins 126 that are positioned into the first positioning hole 201 to realize the positioning of the strip 200 so as to achieve the cutting accuracy. The positioning die 113 is provided with clearance notches 114 to avoid the positioning pins 126, so as to facilitate the insertion of the positioning pins 126 into the first positioning hole 201.

[0031] A positioning die 113 is mounted on a base 14. The base 14 has several upward-extending guide rods 15 that pass through the cutting die assembly 11 and the cutting punch assembly 12. The cutting punch assembly 12 can move up and down along the guide rods 15 to position the cutting die assembly 11 and the cutting punch assembly 12. At the mounting point of the guide rod 15 with the punch assembly 122, a linear bearing is fitted around the outer periphery of the guide rod 15 to facilitate the up and down movement of the cutting punch assembly 12. The base 14 has several through holes 141 communicating with the blanking hole 112. A waste collection box 5 is located below the through holes 141 to receive the cut waste material.

[0032] The cutting mechanism 1 is installed on the mounting frame 4. The mounting frame 4 has limit plates 41 on the left and right sides, limit posts 42 on the front side, and a second fastener 43 on the rear side. The limit plates 41 restrict the left and right movement of the base 14, the limit posts 42 restrict the forward movement of the base 14, and the second fastener 43 installs the base 14 on the mounting frame 4.

[0033] When using the cutting device 100 with automatic feeding function provided in this solution, the material strip 200 is input from the feeding track 2 on the left side, and the material strip is positioned in the second slide 29 and moves forward along the second slide 29. The calibration member 223 is pressed so that the bottom of the calibration member 223 extends into the first positioning hole 201 to position and calibrate the material strip to ensure the accuracy of the position of the material strip 200. Then the feeding module 3 starts to work, and the driving protrusion 33 can extend into the first positioning hole 201 and conform to the shape of the first positioning hole 201. The lower end of the driving protrusion 33 extends into the first clearance opening 26. The first rotation drive member... When the drive disk 32 is driven by 31, the drive protrusion 33 can move the material strip forward, realizing the automatic feeding action. During the feeding process, the first pressing component 21 elastically presses the material strip to prevent it from bending upwards, and the first sensor 23 detects whether the material strip is in a horizontal state. If the material strip is bent or its vertical position is offset, the first sensor 23 will sound an alarm. After being pressed by the second pressing component 24, the material strip enters the first slide groove 111 of the cutting concave die 11. The lifting drive module 13 drives the cutting convex die 12 to descend, and several cutting blades 121 descend simultaneously to cut the material strip. Each material strip 200 needs to be cut at three positions, such as... Figure 7 The three positions indicated by the dashed lines are cut simultaneously at three different locations, cutting the outer circumference strips of three connectors 300 at the same time, which improves the cutting efficiency. The remaining material after cutting falls from the drop hole 112 through the through hole 141 into the waste collection box 5. After cutting, the feeding module 3 on the right side of the feeding track 2 will pull the cut strip forward. The operation process of the feeding module 3 on the right, the first pressing component 21, the calibration component 22, and the first sensor 23 is similar to that on the left side, and will not be described again here. The cut strip 200 enters the subsequent workstation for other operations.

[0034] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
