[0014] Beneficial effects:

[0015] This utility model provides an unloading device for an automatic knife sharpening machine. By rotating the adjusting rod, the slide moves horizontally to achieve precise alignment between the cutter head and the sharpening machine. The locking mechanism with a pin ensures stability after the tool slot is changed. The spring-preloaded pin design allows the cutter head to lock automatically after rotating 180°. The double tool slot structure allows for simultaneous sharpening and tool loading and unloading, significantly improving work efficiency and reducing equipment idle waiting time. It is especially suitable for continuous processing scenarios of batch tools.

[0016] This utility model provides an unloading device for an automatic knife sharpening machine. By setting a combination of bolts, pressure plates and pressure blocks on the cutter disc, and setting two of these combinations, each corresponding to a different knife slot, the bolts can be screwed onto the cutter disc. The pressure plates and pressure blocks can then be used to fix the blades placed in the knife slots, thus facilitating blade fixation. Attached Figure Description

[0022] Please see Figure 1 , Figure 2 , Figure 4 An unloading device for an automatic knife sharpening machine includes a base 1. Support legs 16 are welded to the four corners of the base 1, and mounting holes are provided on the support legs 16. The support legs 16 facilitate installation on a solid support. A sharpening machine 2 is fixedly mounted on the upper right side of the base 1. A slide block 3 is slidably connected to the upper left side of the base 1. A cutter disc 4 is rotatably connected to the front of the slide block 3 via a pivot pin. Two knife grooves 41 are provided on the cutter disc 4. Bolts 5 are threadedly connected to the front of the cutter disc 4. A pressure plate 6 is slidably connected to the outside of the bolts 5. A pressure block 7 is fixedly connected to the pressure plate 6, and the position of the pressure block 7 corresponds to the position of the knife grooves 41. After the bolts 5 are screwed onto the cutter disc 4, the pressure plate 6 and the pressure block 7 can be used to fix the blades placed in the knife grooves 41.

[0023] Please see Figure 2An adjusting block 8 is fixedly connected to the bottom of the slide block 3. The adjusting block 8 passes through the base 1 and is slidably connected to the base 1. A fixed seat 9 is fixedly connected to the bottom of the base 1. An adjusting rod 10 is mounted on the fixed seat 9 via a bearing. The adjusting rod 10 passes through the adjusting block 8 and is threadedly connected to the adjusting block 8. A knob 101 is fixedly connected to the end of the adjusting rod 10, and the knob 101 and the adjusting rod 10 are an integral structure. The knob 101 facilitates the rotation of the adjusting rod 10.

[0024] Please see Figure 3 A fixing plate 11 is fixedly connected to the upper front of the slide block 3. A pin 12 is slidably connected inside the fixing plate 11, and the pin 12 penetrates through the fixing plate 11. One end of the pin 12 is inserted into the cutter head 4, and the other end of the pin 12 is fixedly connected to a pull ring 15. The pin 12 provides a locking function for the cutter head 4 after rotation and repositioning. Two slots are provided on the side of the cutter head 4, and the two slots are symmetrically arranged. The end of the pin 12 is inserted into the slot. The two slots are perpendicular to the two cutter grooves 41, so that the pin 12 can ensure the accuracy of the two cutter grooves 41 after repositioning. A retaining ring 13 is fixedly connected to the pin body of the pin 12, and a spring 14 is sleeved on the outside of the pin body of the pin 12.

The elastic force of the spring 14 can act on the pin 12 through the retaining ring 13.

[0025] Working principle: When in use, first place the blade in the groove 41 on the cutter head 4. Then, after screwing the bolt 5 onto the cutter head 4, the blade placed in the groove 41 can be fixed by the pressure plate 6 and the pressure block 7. The other blade is fixed in the same way. Then, rotate the adjusting rod 10 by the knob 101. The adjusting rod 10 controls the movement of the slide 3 and the cutter head 4 by adjusting the thread with the adjusting block 8 until the blade contacts the grinder 2 and is ground. After grinding, disengage the pin 12 from the cutter head 4, and then rotate the cutter head 4 to swap the two blades. This allows for grinding and loading / unloading of tools at the same time, which significantly improves work efficiency and reduces the idle waiting time of the equipment. It is especially suitable for continuous processing scenarios of batch tools.
