[0053] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] Please see Figures 1-3In this embodiment of the present invention, a feeding mechanism for a slicing tool is provided. The feeding mechanism includes a movable plate 21, a first fixed plate 22, a fixed seat 23, a rotating shaft 24, a movable rod 25, a first cylinder 26, and a second cylinder 27. The movable plate 21 has a plurality of first notches 211, and the first fixed plate 22 has a plurality of second notches 221. The first notches 211 and the second notches 221 are arranged in a crisscross pattern to form a track for placing workpieces. The first fixed plate 22 has an inclined surface for abutting against the workpiece. The fixed seat 23 is respectively installed at both ends of the first fixed plate 22 to fix the first fixed plate 22. The two ends of the rotating shaft 24 are rotatably connected to the fixed seat 23. The rotating shaft 24 is also provided with a rotating rod 28 for driving the movable plate 21 to move. The rotating shaft 24 is provided with a retractable and rotatable rotating shaft 241. One end of the rotating rod 28 is detachably connected to the rotating shaft 241, and the other end of the rotating rod 28 is detachably connected to the left end face of the movable plate 21.

[0055] The upper end of the movable rod 25 is detachably connected to the rotating shaft 241. The output end of the first cylinder 26 is movably connected to the left side of the movable rod 25 for pulling the movable rod 25. The base of the first cylinder 26 is movably connected to the right side of the fixed seat 23. The output end of the second cylinder 27 is movably connected to the lower end of the movable rod 25 for pulling the movable rod 25.

[0056] Among them, such as Figure 1 and Figure 20 As shown, the first notch 211 and the second notch 221 are arranged to intersect each other to form an overlapping area, and a placement groove is opened in the overlapping area to form a track for placing the workpiece.

[0057] The working principle of this embodiment is as follows: During the feeding process, the workpiece to be processed is first placed on the track formed by the first notch 211 and the second notch 221. The upper end of the workpiece rests against the inclined surface of the first fixed plate 22. When the second cylinder 27 is energized, the output end retracts, causing the lower end of the movable rod 25 to move in the retraction direction. The upper end of the movable rod 25 drives the rotating shaft 241 to rotate, and the rotating shaft 241 drives the rotating rod 28 to rotate. The other end of the rotating rod 28 drives the movable plate 21 to move upward. When the movable plate 21 is raised, the height of the first notch 211 becomes higher than the height of the second notch 221. The movable plate 21 lifts the workpiece to be processed upwards. Then, the first cylinder 26 is energized, causing its output end to retract, thereby pulling the movable rod 25. The movable rod 25 drives the rotating shaft 241 to move in the retraction direction of the first cylinder 26. The rotating shaft 241 drives the rotating rod 28 to move in the retraction direction of the first cylinder 26. The rotating rod 28 then drives the entire movable plate 21 to move in the retraction direction of the first cylinder 26. Figure 20 As shown, the moving distance can be the gap distance between the first notch 211 and the second notch 221, and the workpiece to be processed also moves with the movable plate 21.

[0058] Next, extend the output end of the second cylinder 27, causing the lower end of the movable rod 25 to move in the extension direction of the second cylinder 27. The upper end of the movable rod 25 drives the rotating shaft 24 to reverse, causing the other end of the rotating rod 28 to drive the movable plate 21 to descend. The descent of the movable plate 21 causes the height of the first notch 211 to be lower than the height of the second notch 221. The workpiece to be processed falls to the first fixed plate 22. At this time, the position of the workpiece moves a distance in the retraction direction of the first cylinder 26. Then, energize the first cylinder 26 to extend the output end, thereby driving the movable rod 25 to move in the extension direction. The movable rod 25 drives the rotating shaft 241 to move in the extension direction of the first cylinder. The rotating shaft 241 drives the rotating rod 28 to move in the extension direction of the first cylinder 26. The rotating rod 28 then drives the movable plate 21 to move in the extension direction of the first cylinder 26. At this time, the movable plate 21 is reset and completes the feeding of the workpiece by one pitch. By repeating the above steps, continuous feeding of the workpiece can be achieved without manual feeding.

[0059] Further as Figures 4-5 In this embodiment of the present invention, the feeding mechanism further includes a feeding platform 29 and a pushing cylinder 30. The feeding platform 29 has a feeding port 291 on its left side and a sliding groove 292 extending toward the feeding port 291 on its right side. A first slider 2921 is provided in the sliding groove 292. The pushing cylinder 30 is installed on the lower end face of the feeding platform 29 and the output end of the pushing cylinder 30 is connected to the first slider 2921.

[0060] The working principle of this embodiment is as follows: the workpiece to be processed is placed on the feeding table 29 to form a stack. The pusher cylinder 30 is powered on and the output end is retracted, thereby driving the first slider 2921 to move in the retraction direction. The first slider 2921 pushes the lower end of the workpiece out from the feeding port 291, so that the workpiece falls onto the feeding track formed by the cross arrangement of the movable plate 21 and the first fixed plate 22.

[0061] Further as Figure 6 In this embodiment of the present invention, the first fixing plate 22 includes a base plate 225, a first connecting seat 222 and a backing plate 223. The fixing seat 23 has a V-shaped groove 231 for mounting the base plate 225. The base plate 225 is detachably mounted in the V-shaped groove 231 of the fixing seat 23. A second notch 221 is arranged on one side of the base plate 225. The first connecting seat 222 is mounted on the upper end face of the base plate 225. The backing plate 223 is detachably mounted on the first connecting seat 222 to form an inclined surface.

[0062] The working principle of this embodiment is as follows: The first fixing plate 22 can also be formed by assembly as described above. The base plate 225 can be installed on the fixing seat 23 by threaded connection. The connection between the first connecting seat 222 and the base plate 225 includes, but is not limited to, threaded connection. It can also be plugged or tenoned connection. The backing plate 223 is installed on the inclined surface of the first connecting seat 222. The connection between the backing plate 223 and the first connecting seat 222 includes, but is not limited to, threaded connection. The workpiece to be processed is pushed down by the first slider 2921 at the feeding port 291 of the feeding table 29, causing it to flip down and fall onto the feeding track, so that one end of the workpiece rests on the inclined surface of the backing plate 223 and the lower end of the workpiece falls onto the feeding track.

[0063] The first fixing plate 22 can also be integrally formed with a bevel and a second notch 221 for abutting against the workpiece. This integral forming method includes, but is not limited to, machining, injection molding and other methods.

[0064] Further as Figures 7-8 In this embodiment of the utility model, a clamping device for clamping the workpiece is provided at the upper end of the back plate 223. The clamping device includes a second fixed plate 31, an abutment block 32, a spring 33, and a pressing cylinder 34. The second fixed plate 31 is detachably installed on the back plate 223. A second connecting seat 35 is provided on the right side of the second fixed plate 31. The abutment block 32 is rotatably connected in the second connecting seat 35. The spring 33 is installed between the abutment block 32 and the second connecting seat 35. The pressing cylinder 34 is installed on the left side of the second fixed plate 31. A first through hole 311 is opened on the end face of the second fixed plate 31. The first through hole 311 is directly opposite the output end of the pressing cylinder 34. The size of the first through hole 311 is not smaller than the size of the output end of the pressing cylinder 34.

[0065] The working principle of this embodiment is as follows: The feeding mechanism transports the workpiece to the processing position. The clamping device is located at the upper end of the workpiece to be processed. After the pressure cylinder 34 is energized, the output end extends out of the through hole in the second fixed plate 31 and pushes the abutment block 32 to move in the extension direction against the elastic force of the spring 33. Since the abutment block 32 is hinged in the second connecting seat 35, when the upper end of the abutment block 32 is subjected to force and moves in the extension direction of the pressure cylinder 34, the lower end moves in the opposite direction of the extension direction. The lower end of the abutment block 32 moves until it abuts against the workpiece to be processed. The front end of the workpiece is abutted by the lower end of the abutment block 32, and the rear end of the workpiece is abutted by the backing plate 223, so that the workpiece is clamped.

[0066] Further as Figure 9In this embodiment of the present invention, the feeding mechanism is further provided with a cooling device, which includes a third connecting seat 41, a cooling valve 42 and a nozzle 43. The third connecting seat 41 is installed on the right side of the second fixed plate 31, and a second through hole 35 is opened on the end face of the third connecting seat 41. The cooling valve 42 is detachably installed on the upper end face of the second through hole 35, and the nozzle 43 is detachably installed on the lower end face of the second through hole 35. The upper end of the nozzle 43 is connected to the lower end of the cooling valve 42 to form a cooling channel.

[0067] The working principle of this embodiment is as follows: Coolant enters through cooling valve 42 and flows to nozzle 43, from which it is sprayed out from the lower end of nozzle 43. During the processing of the workpiece, the lower end of nozzle 43 is aligned with the grinding position, which can cool the grinding heat generated during the processing of the workpiece, reduce the cutting temperature, and effectively prevent the tool from softening and burning. At the same time, the good cooling performance can also reduce the residual stress on the surface of the workpiece and avoid the generation of processing defects such as thermal cracks and deformation.

[0068] Further as Figure 19 In this embodiment of the present invention, at least one positioning block 224 is provided at the notch of the first fixing plate 22, and the positioning block 224 has a slot 2241 at one end facing outward.

[0069] The working principle of this embodiment is as follows: The slot 2241 of the positioning block 224 faces the gear to ensure the accuracy of each machining position. The slot 2241 is set to position the back of the workpiece so that the workpiece is not easily shaken during machining. The shape of the slot 2241 includes, but is not limited to, V-shape, W-shape, semi-circular arc, or irregular shape. Its shape can be set according to the shape of the workpiece being machined. Figure 22 The slicing blade shown has a V-shaped groove 2241. The slicing blade to be processed can be moved by the movable plate 21 so that its back can rest against the V-shaped groove. The processing position corresponds exactly to the grinding position of the grinding wheel 15. Setting the positioning block 224 is beneficial to improving the processing accuracy and ensuring the quality of the workpiece.

[0070] Further as Figures 1-13 and Figures 21-22In this embodiment of the utility model, a blade-sharpening machine includes a processing table 8. The end face of the processing table 8 includes a blade-sharpening device and the aforementioned feeding mechanism. The blade-sharpening device includes a rotary motor 11, a universal joint shaft 12, a connecting shaft 13, an adjusting seat 14, and a grinding wheel 15. The output end of the rotary motor 11 is provided with a first hinge joint 111 for movably connecting one end of the universal joint shaft 12. One end of the connecting shaft 13 is provided with a second hinge joint 131 for movably connecting the other end of the universal joint shaft 12. The upper end face of the adjusting seat 14 is provided with a fixing block 14. 2. The fixing block 142 has a third through hole 1421. At least one bearing 1422 is provided in the third through hole 1421 so that the connecting shaft 13 is rotatably installed in the third through hole 1421. The grinding wheel 15 is detachably installed at the other end of the connecting shaft 13. When the sharpening device is processing the workpiece, the rotating motor 11 is energized so that the output end of the rotating motor 11 drives the universal joint shaft 12 to rotate. The universal joint shaft 12 drives the connecting shaft 13 to rotate, which in turn drives the grinding wheel 15 to rotate, so as to perform grinding or sharpening of the workpiece.

[0071] The working principle of this embodiment is as follows: Two sharpening devices can be installed at both ends of the feeding mechanism. The sharpening device on the left first performs a rough grinding on the workpiece to be processed. After the rough grinding is completed, the feeding mechanism continues to transport the workpiece to the sharpening device on the right for fine grinding to complete the processing of the workpiece. In the process of processing the slicing blade, the sharpness of the blade edge can be improved and the quality of the blade can be guaranteed.

[0072] The grinding wheel 15 of the sharpening device is located at the feed mechanism's track diameter, and can perform grinding or sharpening of the workpiece. The clamping device and cooling device are located at the grinding wheel 15. When the feed mechanism transports the workpiece to be processed to the grinding wheel 15 for processing, the clamping device first clamps the workpiece to be processed, so that the grinding wheel 15 can prevent the workpiece from shaking when grinding or sharpening the workpiece. The nozzle 43 of the cooling device is aligned with the processing position of the grinding wheel 15 and the workpiece, and the nozzle 43 sprays coolant to remove the grinding heat generated by the workpiece during processing.

[0073] Specifically, by adjusting the feeding pitch of the feeding mechanism, the distance at which the workpiece is conveyed can be set according to the tooth pitch to be processed on the workpiece.

[0074] Further as Figures 14-15 In this embodiment of the present invention, the adjusting seat 14 includes an adjusting plate 141 and a resetting module for resetting the grinding wheel 15. The fixing block 142 is installed on the upper end surface of the adjusting plate 141. The resetting module includes a resetting cylinder 51 and a resetting shaft 52. The adjusting plate 141 is provided with a hinge end 1411 for hinged connection to the output end of the resetting cylinder 51. The lower end of the adjusting plate 141 is provided with an ear plate 1412. Both ends of the resetting shaft 52 are detachably installed on the ear plate 1412.

[0075] By setting a reset shaft 52 at the lower end of the adjusting plate 141, the adjusting plate 141 can rotate around the reset shaft 52 to change the distance between the grinding wheel 15 and the feed rail. When the sharpening device is waiting for the workpiece to be fed to the grinding wheel 15 for processing, or when the next tooth of the cutting blade needs to be ground or sharpened, it is necessary to adjust the distance between the grinding wheel 15 and the feed rail to ensure that when the feeding mechanism moves another tooth pitch, the workpiece is prevented from accidentally touching the grinding wheel 15, which would cause damage to the workpiece.

[0076] Specifically, energizing the reset cylinder 51 causes its output end to retract, which in turn causes the adjusting plate 141 to rotate around the reset shaft 52 in the retraction direction. The rotation of the adjusting plate 141 causes the grinding wheel 15 to rotate around the reset shaft 52, thereby increasing the distance between the grinding wheel 15 and the feed rail. When it is necessary to process the next workpiece or the next tooth of the cutting blade, the feeding mechanism transports the workpiece to be processed to the grinding position of the grinding wheel 15. The output end of the drive reset cylinder extends, causing the adjusting plate 141 to rotate around the reset shaft 52 in the extension direction. The grinding wheel 15 moves closer to the feed rail until it reaches the grinding position, after which the grinding of the workpiece can be performed.

[0077] Further as Figures 16-18 In this embodiment of the utility model, the adjusting seat 14 is provided with a height adjusting module for adjusting the height of the grinding wheel 15. The height adjusting module includes a lead screw 61, a second slider 62, a movable seat 63, and a fixed cover 64. The lead screw 61 is threadedly connected to the second slider 62. Limiting blocks 611 are respectively provided at the front and rear ends of the lead screw 61 to limit the position of the movable seat 63. The side of the second slider 62 is provided with a slanted groove 621. The inner side of the movable seat 63 is provided with a slanted block 631. The slanted block 631 is inserted into the slanted groove 621 to make the movable seat 63 slide in the direction of the slanted groove 621. The fixed cover 64 is detachably installed on the end face of the movable seat 63. The fixed cover 64 is provided with a shaft hole 641 for fitting a reset shaft 52. The reset shaft 52 is rotatably connected in the fixed cover 64.

[0078] The working principle of this embodiment is as follows: Rotary bearings are provided at the openings on both sides of the shaft hole 641 for resetting the shaft 52 to rotate within the fixed cover 64. The fixed cover 64 can be installed on the movable seat 63 by a threaded connection. Specifically, limit blocks 611 are provided at the front and rear ends of the lead screw 61, respectively. The limit blocks 611 are installed on the machining table 8 and restrict the movement of the front and rear ends of the movable seat 63. When it is necessary to adjust the height of the grinding wheel 15, a first knob 75 is provided at one end of the lead screw 61. By turning the first knob 75, the lead screw 61 can be driven to rotate, causing the second slider 62 to slide in the direction of the lead screw 61. The inclined groove 621 on block 62 also slides accordingly. Since the front and rear ends of the movable seat 63 are restricted by the limiting block 611, and the inclined block 631 on the inner side of the movable seat 63 is installed at the inclined groove 621 of the second slider 62, when the second slider 62 is sliding, the inclined block 631 of the movable seat 63 can only move longitudinally under the push of the inclined groove 621 at the second slider 62. When the second slider 62 slides toward the first knob 75, the inclined groove 621 at the second slider 62 pushes the inclined block 631 of the movable seat 63, causing the movable seat 63 to move upward, thereby driving the adjusting seat 14 to move upward, thus raising the position of the grinding wheel 15 located on the adjusting seat 14.

[0079] When the first knob 75 is turned in the opposite direction, the lead screw 61 drives the second slider 62 to slide away from the first knob 75. The inclined groove 621 at the second slider 62 slides synchronously with the second slider 62. The inclined groove 621 pushes the inclined block 631 of the movable seat 63, causing the movable seat 63 to move downward, thereby driving the adjusting seat 14 to move downward, thus lowering the position of the grinding wheel 15 located on the adjusting seat 14.

[0080] Further as Figures 14-15 In this embodiment of the present invention, the adjusting seat 14 is further provided with a lateral adjusting module for adjusting the lateral movement of the grinding wheel 15. The lateral adjusting module includes a second knob 71, a fastener 72, and a threaded sleeve 73. The second knob 71 extends a threaded shaft 711 for connecting the threaded sleeve 73. The left side of the threaded sleeve 73 is detachably mounted on the right side of the ear plate 1412. The threaded sleeve 73 has an internal threaded hole corresponding to the threaded shaft 711. The threaded shaft 711 is threadedly connected to the threaded sleeve 73. The fastener 72 is located inside the threaded sleeve 73. One end of the fastener 72 is connected to one end of the reset shaft 52, and the other end of the fastener 72 is connected to the other end of the threaded shaft 711.

[0081] The working principle of this embodiment is as follows: When the lateral adjustment module adjusts the lateral position of the grinding wheel 15, the reset shaft 52 is installed at the lower end of the adjustment plate 141 by bolts, so that the ear plate 1412 locks both ends of the reset shaft 52. When the lateral position of the grinding wheel 15 needs to be adjusted, the bolts at the ear plate 1412 are loosened, allowing the reset shaft 52 to rotate at the ear plate 1412. The fastener 72 is installed between the threaded shaft 711 and the reset shaft 52 by interference fit, so that the threaded shaft 711 and the reset shaft 52 are separated. Do not lock the fasteners at both ends of 72. When the operator turns the second knob 71, the threaded shaft 711 and the reset shaft 52 can rotate coaxially. The threaded shaft 711 and the threaded sleeve 73 at the second knob 71 are connected by a lead screw 61 and a slider. When the threaded shaft 711 rotates, it can drive the threaded sleeve 73 to slide in the direction of the threaded shaft 711. The threaded sleeve 73 is installed on one side of the ear plate 1412, so it can drive the adjusting plate 141 to move in the direction of the threaded shaft 711, thereby adjusting the lateral position of the grinding wheel 15.
