[0037] Embodiment 1

[0038] Please refer to Figure 1 - Figure 7, An intelligent milling machine for sign processing, including an operating table 1, on which a first sliding seat 2 is slidably installed, a second sliding seat 3 is slidably installed on the first sliding seat 2, a machine base 4 is slidably installed on the second sliding seat 3, a milling head is arranged on the machine base 4, a driving device is arranged between the first sliding seat 2 and the operating table 1, a driving device is arranged between the second sliding seat 3 and the first sliding seat 2, a driving device is arranged between the machine base 4 and the second sliding seat 3. The first sliding seat 2 can move left and right on the operating table 1 by using the driving device, the second sliding seat 3 can move back and forth on the first sliding seat 2 by using the driving device, and the machine base 4 can move up and down on the second sliding seat 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 arts, and it is also a conventional prior art to realize the three-axis movement through the cooperation of the first sliding seat 2, the second sliding seat 3 and the machine base 4. Therefore, its specific structure and working principle will not be elaborated too much. A material table 5 is fixedly installed on the operating table 1, and a backing plate 52 is rotatably installed on the inner wall of the material table 5; a feeding device 6 is arranged on the operating table 1 for automatic feeding; the feeding device 6 includes a mounting frame 61, the mounting frame 61 is fixedly connected to the first sliding seat 2, a connecting frame 62 is fixedly installed on the mounting frame 61, a first clamping block 63 is slidably connected to the connecting frame 62, a second clamping block 64 is fixedly connected to the connecting frame 62, a material box 68 is fixedly installed on the operating table 1, two rotating shafts 69 are rotatably installed at the bottom of the material box 68, a friction roller 610 is fixedly connected to the outer wall of the rotating shaft 69, gears 611 are respectively rotatably connected to the outer walls of both ends of the rotating shaft 69, two racks 612 are slidably installed on the operating table 1, both ends of the first clamping block 63 are respectively connected with a first sliding shaft 65, two groove plates 67 are fixedly installed on the operating table 1, a first sliding groove is arranged on the groove plate 67, both ends of the first sliding groove of the groove plate 67 are bent upward, and the two first sliding shafts 65 are respectively slidably connected with the first sliding grooves of the two groove plates 67. When the two first sliding shafts 65 respectively slide to the bent parts of the first sliding grooves of the two groove plates 67, the two first sliding shafts 65 move upward along the upward-bent parts of the first sliding grooves, so that the two first sliding shafts 65 drive the first clamping block 63 to move upward. Two abutting blocks 66 are connected to the bottom of the connecting frame 62, and when the two abutting blocks 66 move, they respectively contact the ends of the two racks 612 away from the material box 68. A spring is arranged between the end of the rack 612 away from the connecting frame 62 and the bottom of the material box 68. The two gears 611 on the rotating shaft 69 are respectively meshed with the two racks 612. A square groove is arranged at the bottom of the material box 68, and a discharge port is arranged at the bottom of the side of the material box 68 close to the connecting frame 62. The signs to be processed are stacked in the material box 68, and the lowermost sign is located beside the discharge port of the material box 68 (as Figure 4 shown), and both friction rollers 610 are located in the square groove at the bottom of the material box 68 (as Figure 5As shown in the figure, a ratchet and pawl mechanism is provided inside the connection between the gear 611 and the rotating shaft 69. When the gear 611 rotates clockwise, it can drive the rotating shaft 69 to rotate clockwise. When the gear 611 rotates counterclockwise, it does not drive the rotating shaft 69 to rotate. When the two racks 612 move leftward, they can drive the two rotating shafts 69 to rotate clockwise through the four gears 611. The two rotating shafts 69 drive the two friction rollers 610 to rotate clockwise. The top of the friction roller 610 contacts the sign at the bottom of the material box 68 through the square groove of the material box 68, and there is a large frictional force between the friction roller 610 and the sign. When the two friction rollers 610 rotate clockwise, they can drive the bottom sign to move rightward, so that the sign passes through the discharge port of the material box 68. Subsequently, the first clamp 63 and the second clamp 64 clamp the sign and pull it to the right, so that the sign detaches from the material box 68 through the discharge port. When the first slide 2 is about to move rightward in place, the two first slide shafts 65 move upward again along the upwardly curved part of the first chute, so that the first clamp 63 moves upward and releases the clamping of the sign (as Figure 7 shown). The sign slides onto the backing plate 52 by its own gravity. At this time, the automatic feeding process of the sign is completed. Through the setting of the feeding device 6, when the machine base 4 moves rightward, the first clamp 63 and the second clamp 64 cooperate to clamp a sign to be processed and convey it to the backing plate 52 for milling processing, achieving the effect of automatic feeding. When the machine base 4 moves leftward, it mills the sign. When the machine base 4 moves rightward, it realizes automatic feeding, accelerating the coherence of the milling processing and feeding processes, thereby improving production efficiency.

[0039] Furthermore, please refer to Figure 6 - Figure 9 . Two positioning blocks 51 are fixedly installed on the material table 5. Two positioning plates 615 are slidably connected to the material table 5. A slider 616 is slidably connected through the first slide shaft 65. The bottom of the slider 616 is connected to a second slide shaft 617. A second chute is provided on the positioning plate 615. The side of the second chute on the positioning plate 615 away from the positioning block 51 is bent in the direction of approaching the backing plate 52. One end of the second chute of the positioning plate 615 close to the positioning block 51 is provided with an opening (as Figure 8 shown). When the two second slide shafts 617 move, they respectively slide into contact with the second chutes on the two positioning plates 615. While the two second slide shafts 617 slide along the curved part of the second chute, they apply a thrust to the positioning plate 615, so that the two positioning plates 615 move simultaneously in the direction of approaching the backing plate 52. When the two positioning plates 615 move, they can center and align the sign they contact on the backing plate 52, achieving the effects of positioning and positioning the two sides of the sign. Through the cooperation of the two positioning plates 615, during the period from when the sign falls onto the backing plate 52 until milling processing starts, the two positioning plates 615 approach the sign simultaneously, centering and positioning the sign, avoiding the sign from being skewed and affecting the milling operation.

[0040] Further, please refer to Figure 3 , Figure 8 , Figure 9 . There are three adjusting plates 613 slidably connected to the inner wall of the bin 68. The first screw rods 614 are respectively rotatably connected to the three adjusting plates 613. The three first screw rods 614 are all threadedly connected to the bin 68. When the staff rotates the first screw rods 614, the position of the adjusting plates 613 can be adjusted by the principle of threaded connection, so that the staff can adjust the positions of the three adjusting plates 613 in the bin 68 by adjusting the three first screw rods 614, making the three adjusting plates 613 closely adhere to the left side and the front and back sides of the label inside the bin 68, ensuring that the label smoothly slides out from the discharge port of the bin 68 (as shown in Figure 3 ). Two second screw rods 618 are rotatably installed on the connecting frame 62. The two second screw rods 618 are respectively threadedly connected to the two sliders 616. When the second screw rods 618 rotate, the positions of the sliders 616 can be adjusted by the principle of threaded connection. The sliders 616 drive the positioning plates 615 to move through the second sliding shafts 617 (as shown in Figure 9 ), thereby adjusting the positions of the two positioning plates 615 to make the two positioning plates 615 abut against the front and back sides of the label, realizing the adaptation to labels of different specifications.

[0041] In addition, please refer to Figure 1 , Figure 10 - Figure 11 . The rolling device 7 is used to roll and flatten the label before milling the label. The rolling device 7 includes a shaft frame 71, a mounting shaft 72, a flattening roller 73, a folding plate 74 and a third screw rod 79. The shaft frame 71 is slidably installed on the mounting frame 61. The mounting shaft 72 is rotatably connected to the shaft frame 71. The flattening roller 73 is fixedly connected to the outer wall of the mounting shaft 72. When the flattening roller 73 contacts the label, the flattening roller 73 rolls and flattens the label during the movement, so that the contact surface between the milling head and the label can be kept flat, avoiding the influence of local unevenness of the label on the quality of milling. The folding plate 74 is fixedly connected to the bottom of the first sliding seat 2. A plurality of springs are arranged between the folding plate 74 and the bottom of the first sliding seat 2. The third screw rod 79 is rotatably connected to the top surface of the shaft frame 71. The third screw rod 79 is threadedly connected to the mounting frame 61. The milling head of the machine base 4 is located between the flattening roller 73 and the folding plate 74 (as shown in Figure 10 ). The folding plate 74 is made of an elastic material. After the folding plate 74 contacts the label, it deforms and slides along the surface of the label. The folding plate 74 can apply a certain pressure to the label through the elastic force of a plurality of springs, avoiding the local springback of the label during milling after being rolled and flattened. By applying pressure on both sides of the milling head by the folding plate 74 and the flattening roller 73, the flatness of the contact area between the label and the milling head is maintained. Through the setting of the rolling device 7, the flattening roller 73 can roll and flatten the label by rolling before the milling head on the machine base 4 contacts the label, avoiding the influence of local deformation of the label on the milling quality.

[0042] In addition, please refer to Figure 10 - Figure 11 , the rolling device 7 further includes a slide bar 75, a scraping bar 76, a ball ring arm 77 and a grooved shaft 78. The slide bar 75 is slidably connected to the shaft frame 71. The scraping bar 76 is fixedly connected to the outer wall of the slide bar 75. The grooved shaft 78 is connected to one end of the mounting shaft 72. The ball ring arm 77 is connected to one end of the slide bar 75 close to the grooved shaft 78. The grooved shaft 78 is provided with an annular inclined groove. The ball ring arm 77 is sleeved on the grooved shaft 78. The inner wall of the ball ring arm 77 is provided with balls. The balls of the ball ring arm 77 are slidably connected to the annular inclined groove of the grooved shaft 78. The scraping bar 76 is in sliding contact with the outer wall of the flattening roller 73. When the flattening roller 73 rolls, it drives the grooved shaft 78 to rotate. When the grooved shaft 78 rotates, it drives the ball ring arm 77 to move back and forth through the cooperation of the annular inclined groove and the balls (as shown in Figure 11 ), and the ball ring arm 77 drives the scraping bar 76 to reciprocate back and forth through the slide bar 75. Since some debris generated during milling processing will adhere to the flattening roller 73, the reciprocating movement of the scraping bar 76 can scrape off the debris adhering to the flattening roller 73, maintaining the cleanliness of the contact surface between the flattening roller 73 and the sign. Through the setting of the scraping bar 76, the scraping bar 76 can continuously clean the flattening roller 73, avoiding damage to the sign caused by debris adhering to the flattening roller 73.

[0043] It should be noted 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 limit blocks 81, two limit rods 82, two convex blocks 83 and an elastic support plate 84. A square hole is provided on the operation table 1. The elastic support plate 84 is fixedly installed in the square hole of the operation table 1. The elastic support plate 84 is located below the connection between the cushion plate 52 and the material table 5. A plurality of springs are provided between the elastic support plate 84 and the bottom surface of the cushion plate 52. The two limit blocks 81 are respectively fixedly connected to the outer walls of one end of the cushion plate 52 away from the elastic support plate 84. The two limit rods 82 are both slidably connected through the material table 5. The limit blocks 81 are provided with limit holes. The two limit rods 82 are respectively inserted into the limit holes of the two limit blocks 81. The two convex blocks 83 are respectively fixedly installed at one ends of the two limit rods 82 away from the cushion plate 52. The two convex blocks 83 are both located on the movement track of the flattening roller 73. After the flattening roller 73 contacts the two convex blocks 83, the flattening roller 73 pulls out the two limit rods 82 from the limit holes of the two limit blocks 81 through the two convex blocks 83, and the two limit rods 82 no longer limit and fix the two limit blocks 81. A spring is provided between the convex block 83 and the material table 5 (as shown in Figure 12As shown in the figure, the blanking device 8 further includes a slide plate 85 and a collection box 86. The slide plate 85 is fixedly connected to the inner wall of the operation table 1. The slide plate 85 is located below the backing plate 52. The collection box 86 is movably installed inside the operation table 1. The collection box 86 is located below the slide plate 85. When there is no nameplate on the backing plate 52, multiple springs on the elastic support plate 84 can support the backing plate 52 to keep the backing plate 52 horizontal. When there is a nameplate on the backing plate 52, due to the influence of the self-gravity of the nameplate, the overall weight of the backing plate 52 increases, and multiple springs contract and deform, and the backing plate 52 turns downward. After the backing plate 52 tilts downward, the nameplate slides onto the slide plate 85 along the backing plate 52 through the square hole of the operation table 1, and then slides into the collection box 86 through the slide plate 85 for collection. When the nameplate detaches from the backing plate 52, multiple springs of the elastic support plate 84 drive the backing plate 52 to reset through the elastic force, so that the backing plate 52 remains horizontal again, achieving the effect of automatic blanking. The flattening roller 73 disengages from the two bumps 83, and the two bumps 83 drive the two limit rods 82 to move rightward by the elastic force of the spring, so that the two limit rods 82 limit and fix the two limit blocks 81 again. Through the setting of the blanking device 8, the backing plate 52 can automatically turn down after the nameplate processing is completed, and the nameplate slides into the collection box 86 through the slide plate 85 for collection (as Figure 13 shown in the figure), achieving the effect of automatic blanking, reducing the operation steps of manual blanking, and further improving the automation level.

[0044] Adopting the above structure, the working principle of this case is that the up-down, front-back, left-right position relationships in the following text are all based on Figure 1For reference, the first slide 2 can move left and right on the operating table 1 by means of a driving device, the second slide 3 can move back and forth on the first slide 2 by means of a driving device, and the machine base 4 can move up and down on the second slide 3 by means of a 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 arts, and it is also a conventional prior art to realize three-axis movement through the cooperation of the first slide 2, the second slide 3 and the machine base 4. Therefore, their specific structures and working principles will not be elaborated too much. When milling processing is required, the nameplates to be processed are stacked in the feed box 68, and the lowermost nameplate is located beside the discharge port of the feed box 68. The initial position of the first slide 2 is at the rightmost side. After the first slide 2 is started, it moves leftward close to the feed box 68. When the first slide 2 moves, it drives the connecting frame 62 to move synchronously through the mounting frame 61. The connecting frame 62 drives the first clamping block 63, the second clamping block 64 and the two abutting blocks 66 to move synchronously. During the leftward movement of the two abutting blocks 66, they contact the two racks 612 and push the two racks 612 leftward. Each rack 612 meshes with the two gears 611. When the rack 612 moves leftward, it can drive the two gears 611 to rotate clockwise. When the abutting block 66 does not contact the rack 612, the rack 612 is reset by the elastic force of the spring. When the rack 612 is reset, it drives the gear 611 to rotate counterclockwise. A ratchet and pawl mechanism is arranged inside the connection part of the gear 611 and the rotating shaft 69. The ratchet and pawl mechanism is a relatively conventional one-way limit transmission mechanism, and its specific structure will not be elaborated. Through the cooperation of the ratchet and pawl, the gear 611 can drive the rotating shaft 69 to rotate clockwise when it rotates clockwise, and the gear 611 does not drive the rotating shaft 69 to rotate when it rotates counterclockwise. Therefore, when the two racks 612 move leftward, they can drive the two rotating shafts 69 to rotate clockwise through the four gears 611. The two rotating shafts 69 drive the two friction rollers 610 to rotate clockwise. The top of the friction roller 610 contacts the lowermost nameplate in the feed box 68 through the square groove of the feed box 68, and there is a large frictional force between the friction roller 610 and the nameplate, so that when the two friction rollers 610 rotate clockwise, they can drive the lowermost nameplate to move rightward, and make the nameplate pass through the discharge port of the feed box 68;Both ends of the first chute of the chute plate 67 are bent upward. When the first clamping block 63 moves, it drives the two first sliding shafts 65 to move synchronously. When the two first sliding shafts 65 slide to the bent parts of the first chutes of the two chute plates 67 respectively, the two first sliding shafts 65 move upward at the upward-bent parts of the first chutes, so that the two first sliding shafts 65 drive the first clamping block 63 to move upward. During the leftward movement of the connecting frame 62, when the rack 612 starts to move, the two friction rollers 610 start to rotate. At the same time, the two first sliding shafts 65 start to move upward along the upward-bent parts of the first chutes, and the first clamping block 63 moves upward accordingly, increasing the distance between the first clamping block 63 and the second clamping block 64. The sign extending leftward from the discharge port finally enters between the first clamping block 63 and the second clamping block 64. When the first sliding seat 2 moves leftward in place, a part of the sign is located between the first clamping block 63 and the second clamping block 64. Subsequently, the first sliding seat 2 turns to move rightward. 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 move downward and reset along the bent parts of the first chutes, making the first clamping block 63 approach the second clamping block 64 again. Both the first clamping block 63 and the second clamping block 64 are provided with elastic materials with a high coefficient of friction, so that when the first clamping block 63 and the second clamping block 64 approach each other, they can clamp the sign between them. When the first clamping block 63 moves upward, the sign is moving rightward, and the first clamping block 63 does not contact the sign during movement. When the first clamping block 63 starts to move downward, the sign has already been located below the first clamping block 63, so that after the first clamping block 63 moves downward, it clamps the sign with the second clamping block 64. During the process of the connecting frame 62 following the first sliding seat 2 to move rightward, the first clamping block 63 and the second clamping block 64 keep clamping the sign and pulling it rightward, so that the sign detaches from the material box 68 through the discharge port. Subsequently, when the first sliding seat 2 is about to move rightward in place, the two first sliding shafts 65 move upward again along the upward-bent parts of the first chutes, so that after the first clamping block 63 moves upward, it releases the clamping of the sign, and the sign slides onto the cushion plate 52 by its own gravity. After the sign slides onto the cushion plate 52, it is located to the right of the two positioning blocks 51. At this time, the automatic feeding process of the sign is completed. During the next leftward movement of the first sliding seat 2, the milling head on the machine base 4 mills the sign during the leftward movement.;

[0045] When the first sliding seat 2 starts to move leftward, the two first sliding shafts 65 drive the two second sliding shafts 617 to move synchronously through the two sliders 616. The side of the second sliding groove on the positioning plate 615 away from the positioning block 51 is set to bend towards the pressing plate 52. After the two first sliding shafts 65 descend, the two second sliding shafts 617 respectively enter the bent parts of the second sliding grooves of the two positioning plates 615. Subsequently, while the two second sliding shafts 617 slide along the bent parts of the second sliding grooves, they apply a thrust to the positioning plates 615, causing the two positioning plates 615 to move towards the pressing plate 52 simultaneously. When the two positioning plates 615 move, they can center the contacted signs on the pressing plate 52, achieving the effects of positioning and positioning both sides of the signs. An opening is provided at one end of the second sliding groove of the positioning plate 615 close to the positioning block 51. After the milling operation is completed, the two second sliding shafts 617 slide out through the openings of the second sliding grooves of the two positioning plates 615, and then the process of loading the next sign is carried out. When the two second sliding shafts 617 turn to move rightward, they enter the second sliding grooves of the two positioning plates 615 again through the openings. When the first clamping block 63 is about to move upward, the two second sliding shafts 617 drive the two positioning plates 615 to move away from the pressing plate 52 again through the bent parts of the second sliding grooves of the two positioning plates 615. Subsequently, the next sign falls onto the pressing plate 52, and the two second sliding shafts 617 move upward with the two first sliding shafts 65 and temporarily disengage from the second sliding grooves of the two positioning plates 615.

[0046] Conventional milling operations usually involve processing a certain batch of signs of the same specification. When signs of different widths need to be processed, the material box 68 is rectangular, and 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 operator rotates the first screw 614 to adjust the position of the adjusting plate 613 using the principle of threaded connection, enabling the operator to adjust the positions of the three adjusting plates 613 in the material box 68 by adjusting the three first screws 614, so that the three adjusting plates 613 are closely attached to the left side and the front and rear sides of the signs inside the material box 68, ensuring that the signs smoothly slide out from the discharge port of the material box 68. Take a sign in advance and place it on the backing plate 52, and adjust the position of the first sliding seat 2 so that the connecting frame 62 is located above the backing plate 52. At this time, the two second sliding shafts 617 have driven the two positioning plates 615 close to the backing plate 52. Then rotate the two second screws 618. When the second screws 618 rotate, they can adjust the position of the slider 616 using the principle of threaded connection. The slider 616 drives the positioning plate 615 to move through the second sliding shaft 617, thereby adjusting 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, achieving the adaptation to signs of different specifications; through the setting of the feeding device 6, when the machine base 4 moves to the right, the first clamping block 63 and the second clamping block 64 cooperate to clamp a sign to be processed and convey it to the backing plate 52 for waiting for milling processing, achieving the effect of automatic feeding. When the machine base 4 moves to the left, it mills the sign, and when the machine base 4 moves to the right, it realizes automatic feeding, accelerating the coherence of the milling processing and feeding processes, thereby improving production efficiency; through the cooperation of the two positioning plates 615, during the period from when the sign falls onto the backing plate 52 until milling processing starts, the two positioning plates 615 approach the sign simultaneously, centering and positioning the sign, avoiding the sign from being skewed and affecting the milling operation.

[0047] When the mounting frame 61 moves, it drives the shaft frame 71 to move synchronously, the shaft frame 71 drives the mounting shaft 72 to move synchronously, and the mounting shaft 72 drives the flattening roller 73 to move synchronously. When adjusting the positions of the two positioning plates 615 in the above text, the third screw 79 is rotated. When the third screw 79 rotates, the upper and lower positions of the shaft frame 71 are adjusted by the principle of threaded connection, so that the bottom of the flattening roller 73 is tightly against the sign. Then, during the subsequent milling process, before the milling head of the machine base 4 contacts the sign, the flattening roller 73 contacts the sign first, and the flattening roller 73 rolls the sign flat during the left movement. The contact surface between the milling head and the sign can be kept flat to avoid local unevenness of the sign affecting the quality of the milling process. At the same time, the flattening roller 73 uses friction to push the sign to the left, so that the left end of the sign is 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. After contacting the sign, the angle plate 74 is deformed and slides along the surface of the sign. The angle plate 74 can be adjusted by the elastic force of multiple springs. The sign is subjected to a certain pressure to prevent the local part of the sign that has been rolled and flattened from rebounding during milling. The angled plate 74 and the flattening roller 73 exert pressure on both sides of the milling head to maintain the flatness of the contact area between the sign and the milling head. The flattening roller 73 drives the groove shaft 78 to rotate when rolling. When the groove shaft 78 rotates, the cooperation between the annular inclined groove and the ball drives the ball ring arm 77 to move back and forth. The ball ring arm 77 drives the scraper 76 to move back and forth through the slide bar 75. Since some debris generated during milling will adhere to the flattening roller 73, when the scraper 76 moves back and forth The flattening roller 73 can be scraped off the debris attached to the flattening roller 73, so as to maintain the cleanliness of the contact surface between the flattening roller 73 and the nameplate, and avoid the flattening roller 73 being attached with a lot of debris, which may cause damage to the nameplate surface during rolling. Through the setting of the rolling device 7, the flattening roller 73 can use rolling to roll the nameplate flat before the milling head on the machine base 4 contacts the nameplate, so as to avoid local deformation of the nameplate and affect the milling quality; through the setting of the scraper bar 76, the scraper bar 76 can continuously clean the flattening roller 73, so as to avoid the flattening roller 73 being attached with debris, which may cause damage to the nameplate.

[0048] During the milling operation, the two limit rods 82 are inserted into the limit holes of the two limit blocks 81, so that the two limit rods 82 limit and fix the pad 52 through the two limit blocks 81, and the pad 52 remains horizontal. When the milling head on the machine base 4 completes the milling operation, the flattening roller 73 contacts the two protrusions 83, and then the flattening roller 73 drives the two limit rods 82 to move left through the two protrusions 83, and the two limit rods 82 are pulled out of the limit holes of the two limit blocks 81. The limiting rod 82 no longer limits and fixes the two limiting blocks 81. In this case, when there is no sign on the pad 52, the multiple springs on the elastic support plate 84 can support the pad 52 to keep the pad 52 horizontal. When there is a sign on the pad 52, due to the influence of the sign's own gravity, the overall weight of the pad 52 increases, the multiple springs shrink and deform, and the pad 52 flips downward. After the pad 52 tilts downward, the sign slides along the pad 52 through the square hole of the operating table 1 to The label is then moved onto the slide plate 85 and then slid into the collection box 86 for collection. When the label is detached from the pad 52, the multiple springs of the elastic support plate 84 drive the pad 52 to reset through the elastic force, so that the pad 52 remains horizontal again, achieving the effect of automatic unloading. During the automatic unloading process, the first clamp 63 and the second clamp 64 are moving left to clamp the label. Subsequently, when the first clamp 63 and the second clamp 64 transport the next label to the left, the flattening roller 73 detaches from the two protrusions 83. The two protrusions 83 use the elastic force of the springs to drive the two limit rods 82 to move right, so that the two limit rods 82 again limit and fix the two limit blocks 81. Through the setting of the unloading device 8, the pad 52 can automatically flip down after the label processing is completed, so that the label slides into the collection box 86 through the slide plate 85 for collection, achieving the effect of automatic unloading, reducing the operating steps of manual unloading, and further improving the level of automation.
