Through the cooperation of the two positioning plates 615, the label is centered and positioned by the two positioning plates 615 at the same time from the time it falls onto the base plate 52 to the start of milling, avoiding the influence of the label skew on the milling operation.

[0043] It is worth noting that, please refer to Figure 1 、 Figure 12 - Figure 13 , the blanking device 8 is used for automatic blanking; the blanking device 8 includes two limiting blocks 81, two limiting rods 82, two protruding blocks 83 and a spring supporting plate 84, a square hole is arranged on the operation table 1, the spring supporting plate 84 is fixedly installed in the square hole of the operation table 1, the spring supporting plate 84 is located below the connecting place between the backing plate 52 and the material table 5, a plurality of springs are arranged between the spring supporting plate 84 and the bottom surface of the backing plate 52, two limiting blocks 81 are respectively fixedly connected to the outer wall of one end of the backing plate 52 away from the spring supporting plate 84, two limiting rods 82 are both slidingly connected to the material table 5, limiting holes are arranged on the limiting blocks 81, two limiting rods 82 are respectively inserted into the limiting holes of the two limiting blocks 81, two protruding blocks 83 are respectively fixedly installed at one end of the two limiting rods 82 away from the backing plate 52, the two protruding blocks 83 are both located on the movement track of the flattening roller 73, after the flattening roller 73 is contacted with the two protruding blocks 83, the flattening roller 73 pulls out the two limiting rods 82 from the limiting holes of the two limiting blocks 81 through the two protruding blocks 83, the two limiting rods 82 are no longer limited and fixed to the two limiting blocks 81, springs are arranged between the protruding blocks 83 and the material table 5 (as Figure 12As shown), the feeding device 8 also includes a slide plate 85 and a collection box 86. The slide plate 85 is fixedly connected to the inner wall of the operating table 1 and is located below the pad 52. The collection box 86 is movably installed inside the operating table 1 and is located below the slide plate 85. When there is no label on the pad 52, multiple springs on the elastic support plate 84 can support the pad 52 and keep the pad 52 horizontal. When there is a label on the pad 52, due to the weight of the label itself, the overall weight of the pad 52 increases, the multiple springs contract and deform, the pad 52 flips downward, and after the pad 52 tilts downward, the label passes through the square hole of the operating table 1 along the pad 52. The label slides onto the slide plate 85 and then slides onto the collection box 86 for collection. After the label detaches from the pad 52, multiple springs on the elastic support plate 84 use their elasticity to reset the pad 52, keeping it horizontal again, achieving automatic feeding. The flattening roller 73 disengages from the two protrusions 83, and the two protrusions 83 use their springs to move the two limiting rods 82 to the right, causing the two limiting rods 82 to again limit and fix the two limiting blocks 81. Through the setting of the feeding device 8, the pad 52 can automatically flip down after the label processing is completed, allowing the label to slide onto the slide plate 85 and into the collection box 86 for collection (e.g., ...). Figure 13 As shown in the figure, it achieves the effect of automatic material feeding, reduces the number of manual material feeding operations, and further improves the level of automation.

[0044] Using the above structure, the working principle of this case is that the top-bottom, front-back, left-right positional relationships in the following text are all based on... Figure 1As a reference, the first slide 2 can move left and right on the operation table 1 by using the driving device, the second slide 3 can move forward and backward on the first slide 2 by using the driving device, and the machine base 4 can move up and down on the second slide 3 by using the driving device, so as to realize the three-axis movement of the machine base 4. The machine base 4 and the milling head are both prior art, and the cooperation of the first slide 2, the second slide 3 and the machine base 4 to realize three-axis movement is also a conventional prior art, so the specific structure and working principle will not be described in detail. When milling is needed, the to-be-processed signs are stacked in the material box 68, the lowest sign is beside the discharge port of the material box 68, and the initial position of the first slide 2 is on the rightmost side. After the first slide 2 is started, it moves left to approach the material box 68. When the first slide 2 moves, the connecting frame 62 is driven to move synchronously by the mounting frame 61, the first clamping block 63, the second clamping block 64 and the two abutting blocks 66 are driven to move synchronously by the connecting frame 62, and the two abutting blocks 66 contact the two racks 612 during left movement and push the two racks 612 leftward. Each rack 612 is engaged with two gears 611, and the rack 612 can drive the two gears 611 to rotate clockwise when moving left. When the abutting block 66 is not in contact with the rack 612, the rack 612 is reset by the elastic force of the spring, and the rack 612 drives the gear 611 to rotate counterclockwise when resetting. The connection between the gear 611 and the shaft 69 is internally provided with a ratchet and pawl mechanism, which is a relatively common one-way limiting transmission mechanism, and its specific structure will not be described in detail. Through the cooperation of the ratchet and pawl, the gear 611 can drive the shaft 69 to rotate clockwise when rotating clockwise, and the gear 611 cannot drive the shaft 69 to rotate when rotating counterclockwise. Therefore, when the two racks 612 move left, the two shafts 69 can be driven to rotate clockwise by the four gears 611, the two shafts 69 drive the two friction rollers 610 to rotate clockwise, the top of the friction roller 610 is in contact with the bottommost sign in the material box 68 through the square groove of the material box 68, and there is a large friction force between the friction roller 610 and the sign, so that the two friction rollers 610 can drive the bottommost sign to move right when rotating clockwise, and the sign passes through the discharge port of the material box 68.The first sliding groove of the groove plate 67 is curved upward at both ends, and the first clamping block 63 moves synchronously with the two first sliding shafts 65. When the two first sliding shafts 65 slide to the curved positions of the first sliding grooves of the two groove plates 67, the two first sliding shafts 65 move upward at the curved positions of the first sliding grooves, so that the two first sliding shafts 65 move the first clamping block 63 upward. During the left movement of the connecting frame 62, when the two racks 612 start to move, the two friction rollers 610 start to rotate, and at the same time, the two first sliding shafts 65 start to move upward along the curved positions of the first sliding grooves, and the first clamping block 63 moves upward, so that the distance between the first clamping block 63 and the second clamping block 64 increases. The signboard that moves right out of the discharge port finally enters between the first clamping block 63 and the second clamping block 64. When the first sliding seat 2 moves to the left, a part of the signboard is located between the first clamping block 63 and the second clamping block 64. Then, the first sliding seat 2 moves to the right, the two racks 612 are reset by the elastic force of the spring, the two friction rollers 610 do not rotate, and the two first sliding shafts 65 reset downward along the curved positions of the first sliding grooves, so that the first clamping block 63 is close to the second clamping block 64 again. The first clamping block 63 and the second clamping block 64 are both provided with elastic materials with high friction coefficients, so that the first clamping block 63 and the second clamping block 64 can clamp the signboard between them when they approach each other. When the first clamping block 63 moves upward, the signboard is moving to the right, and the first clamping block 63 does not contact the signboard during movement. When the first clamping block 63 starts to move downward, the signboard is already below the first clamping block 63, so that the first clamping block 63 is clamped with the second clamping block 64 after moving downward. During the right movement of the connecting frame 62 following the first sliding seat 2, the first clamping block 63 and the second clamping block 64 keep clamping and pulling the signboard to the right, so that the signboard is separated from the material box 68 through the discharge port. Then, when the first sliding seat 2 is about to move to the right, the two first sliding shafts 65 move upward along the curved positions of the first sliding grooves again, so that the first clamping block 63 moves upward and releases the clamping of the signboard. The signboard slides to the pad plate 52 under its own gravity, and the signboard is located to the right of the two positioning blocks 51 after sliding to the pad plate 52. At this time, the automatic feeding process of the signboard is completed. When the first sliding seat 2 moves to the left next time, the milling head on the base 4 mills the signboard during left movement.

[0045] When the first sliding seat 2 starts to move left, the two first sliding shafts 65 drive the two second sliding shafts 617 to move synchronously through the two sliding blocks 616. The second sliding groove on the positioning plate 615 is set to be curved towards the direction of approaching the base plate 52 at the side away from the positioning block 51. After the two first sliding shafts 65 descend, the two second sliding shafts 617 enter the curved parts of the second sliding grooves of the two positioning plates 615 respectively. Subsequently, the two second sliding shafts 617 slide along the curved parts of the second sliding grooves while exerting a pushing force on the positioning plates 615, so that the two positioning plates 615 move towards the direction of approaching the base plate 52 at the same time. When the two positioning plates 615 move, they can center the sign plates they contact and place them on the base plate 52, thereby achieving the effect of positioning and positioning the two sides of the sign plate. The end of the second sliding groove of the positioning plate 615 close to the positioning block 51 is provided with an opening. When the milling operation is completed, the two second sliding shafts 617 slide out through the opening of the second sliding groove of the two positioning plates 615, and the subsequent process of feeding the next sign plate is performed. When the two second sliding shafts 617 move right, they re-enter the second sliding groove of the two positioning plates 615 through the opening. When the first clamping block 63 is about to move up, the two second sliding shafts 617 drive the two positioning plates 615 to move away from the base plate 52 again through the curved parts of the second sliding grooves of the two positioning plates 615. Subsequently, the next sign plate falls onto the base plate 52. The two second sliding shafts 617 move up with the two first sliding shafts 65 and temporarily disengage from the second sliding groove of the two positioning plates 615.

[0046] The conventional milling processing is usually to process a certain batch of the same specification of the sign, when the signs of different widths need to be processed, the material box 68 is rectangular, the three adjusting plates 613 are respectively located on the left side and the front and rear inner walls of the material box 68, the worker rotates the first screw rod 614 to adjust the position of the adjusting plate 613 by using the screw connection principle, so that the worker adjusts the positions of the three adjusting plates 613 in the material box 68 by adjusting the three first screw rods 614, so that the three adjusting plates 613 tightly abut against the left side and the front and rear sides of the sign in the material box 68, to ensure that the sign smoothly slides out of the discharge port of the material box 68, and a sign is taken in advance and placed on the base plate 52, the position of the first sliding seat 2 is adjusted, so that the connecting frame 62 is located above the base plate 52, at this time, the two second sliding shafts 617 have driven the two positioning plates 615 to approach the base plate 52, at this time, the two second screw rods 618 are rotated, the second screw rod 618 rotates to adjust the position of the sliding block 616 by using the screw connection principle, the sliding block 616 drives the positioning plate 615 to move through the second sliding shaft 617, so as to adjust the positions of the two positioning plates 615, so that the two positioning plates 615 abut against the front and rear sides of the sign, to realize the adaptation to different specifications of the sign; through the setting of the feeding device 6, when the base 4 moves to the right, the first clamping block 63 and the second clamping block 64 clamp and convey a sign to be processed to the base plate 52 for waiting for milling processing, so as to realize the effect of automatic feeding, when the base 4 moves to the left, the sign is milled, when the base 4 moves to the right, automatic feeding is realized, the continuity of the milling processing and the feeding process is accelerated, so as to improve the production efficiency; through the cooperation of the two positioning plates 615, the two positioning plates 615 approach the sign at the same time during the period from the sign falling on the base plate 52 to the start of milling processing, to centrally position the sign, to avoid the sign being skewed to affect the milling operation.

[0047] When the mounting frame 61 moves, the shaft frame 71 moves synchronously, the mounting shaft 72 moves synchronously, the flattening roller 73 moves synchronously, when adjusting the positions of the two positioning plates 615, rotating the third screw 79, and adjusting the up-down position of the shaft frame 71 through the screw connection principle, the bottom of the flattening roller 73 tightly abuts against the sign, then, before the milling head of the machine base 4 contacts the sign during subsequent milling processing, the flattening roller 73 contacts the sign first, the flattening roller 73 rolls and flattens the sign during left movement, so that the contact surface of the milling head and the sign can remain flat, avoiding that local unevenness of the sign affects the milling quality, at the same time, the flattening roller 73 pushes the sign to the left by friction, so that the left end of the sign abuts against the two positioning blocks 51, at this time, the sign is positioned and fixed by the two positioning blocks 51 and the two positioning plates 615, when the milling head contacts the sign, the angle plate 74 contacts the surface of the sign, the angle plate 74 is made of elastic material, deforms after contacting the sign, and slides along the surface of the sign, the angle plate 74 can exert a certain pressure on the sign through the elastic force of multiple springs, avoiding that the locally deformed sign rebounds during milling, the angle plate 74 and the flattening roller 73 pressurize on both sides of the milling head, so as to maintain the flatness of the contact area of the sign and the milling head; when the flattening roller 73 rolls, the groove shaft 78 rotates, the groove shaft 78 drives the ball ring arm 77 to move back and forth through the cooperation of the annular chute and the ball, the ball ring arm 77 drives the scraping strip 76 to move back and forth through the slide rod 75, since part of the debris generated during milling processing will adhere to the flattening roller 73, the scraping strip 76 can scrape off the debris adhering to the flattening roller 73 when moving back and forth, so as to maintain the cleanliness of the contact surface of the flattening roller 73 and the sign, avoiding that the flattening roller 73 is damaged due to adhesion of too much debris on the surface, through the setting of the flattening device 7, the flattening roller 73 can roll and flatten the sign before the milling head of the machine base 4 contacts the sign, avoiding that local deformation of the sign affects the milling quality; through the setting of the scraping strip 76, the scraping strip 76 can continuously clean the flattening roller 73, avoiding that the flattening roller 73 is damaged due to adhesion of debris.

[0048] In the milling operation, two limiting rods 82 are inserted into the limiting holes of two limiting blocks 81, so that the two limiting rods 82 limit and fix the base plate 52 through the two limiting blocks 81, and the base plate 52 remains horizontal. When the milling head on the machine seat 4 completes the milling operation, the flattening roller 73 contacts the two protrusions 83, and then the flattening roller 73 drives the two limiting rods 82 to move left through the two protrusions 83, so that the two limiting rods 82 are pulled out of the limiting holes of the two limiting blocks 81, and the two limiting rods 82 no longer limit and fix the two limiting blocks 81. In this case, when there is no label on the base plate 52, the multiple springs on the elastic supporting plate 84 can support the base plate 52, so that the base plate 52 remains horizontal. When there is a label on the base plate 52, the overall weight of the base plate 52 increases due to the influence of the self-gravity of the label, the multiple springs shrink and deform, and the base plate 52 overturns downward. After the base plate 52 inclines downward, the label slides along the base plate 52 through the square hole of the operation table 1 to the sliding plate 85, and then slides to the collecting box 86 through the sliding plate 85 for collection. After the label is separated from the base plate 52, the multiple springs of the elastic supporting plate 84 drive the base plate 52 to reset through the elastic force, so that the base plate 52 remains horizontal again, achieving the effect of automatic unloading. In the process of automatic unloading, the first clamping block 63 and the second clamping block 64 are moving left to clamp the label. Then, when the first clamping block 63 and the second clamping block 64 transport the next label to the right, the flattening roller 73 is separated from the two protrusions 83, and the two protrusions 83 drive the two limiting rods 82 to move right through the elastic force of the spring, so that the two limiting rods 82 limit and fix the two limiting blocks 81 again. Through the setting of the unloading device 8, the base plate 52 can automatically overturn after the label processing is completed, so that the label slides to the collecting box 86 through the sliding plate 85 for collection, achieving the effect of automatic unloading, reducing the operation steps of manual unloading, and further improving the automation level.
