Description

Technical Field

[0001] This utility model relates to the field of decal cutting technology, and in particular to a decal cutting platform lifting mechanism. Background Technology

[0002] A decal cutting platform is a device used in the ceramics, glass, metal, or other surface decoration industries to precisely cut patterns printed or transferred onto paper according to specific shapes, sizes, and paths. Its core function is to accurately cut the pattern from the base paper according to the actual outline of the printed pattern on the decal, while ensuring the quality of the cut edges and the integrity of the pattern.

[0003] Early decal cutting lifting mechanisms mostly adopted a single lead screw drive and sliding guide rail structure. The servo motor drove the platform to lift and lower through a single trapezoidal lead screw, the sliding guide rail provided guidance, and contact micro switches provided limit protection. Because the single lead screw has weak resistance to off-center loads, the platform will tilt when the load is uneven, causing the cutting head to be non-perpendicular to the material surface. To solve the above problems, a dual ball screw synchronous drive and linear guide rail structure was adopted, combined with servo motor closed-loop control, and the dual lead screw synchronous belt achieved constant speed movement. High-precision ball screws were used to reduce the tilt angle. However, in actual use, due to uneven stacking of decals or the curvature of the material itself, the cutting could not adapt to the surface undulations through dynamic height adjustment, resulting in the cutting head colliding or missing cuts, which could not meet the needs of users.

The adjustment mechanism 2 includes a bidirectional lead screw 201 for precisely moving a moving block 205 in opposite directions. The front and rear ends of the bidirectional lead screw 201 are rotatably connected to the left and right sides of the inner wall of the housing 1.

The output end of the stepper motor 203 passes through the housing 1 and is fixedly connected to a worm gear 204. The worm gear 204 and the worm gear 204 are connected to the worm gear 204. 2. Engaging connection: Stepper motor 203 transmits precise rotational power to bidirectional lead screw 201 via worm gear 202 and worm 204. Moving blocks 205 are slidably connected to the left and right sides of the outer wall of bidirectional lead screw 201. Slide grooves 206 are provided on the left and right sides of the top of housing 1. The tops of the two moving blocks 205 are slidably connected to the inner walls of their respective slide grooves 206. When bidirectional lead screw 201 rotates, the moving blocks 205 move precisely within the slide grooves 206. Wedge block 1 207 is fixedly connected to the top of each of the two moving blocks 205. When the moving blocks 205 move, they drive wedge block 1 207 to move together. A top plate 208 is provided on the top of housing 1. Wedge block 209 is fixedly connected to the left and right sides of the bottom of the top plate 208. The bottom parts of the two wedge blocks 209... The top of the wedge 207 is slidably connected to the corresponding wedge 207. The wedge 207 can control the raising and lowering of the top plate 208 by contacting the wedge 209. The bottom left and right sides of the housing 1 are provided with a longitudinal sliding assembly 211, and the top of the top plate 208 is provided with a transverse sliding assembly 210. The longitudinal sliding assembly 211 includes two sliders 2111, the tops of which are fixedly connected to the bottom left and right sides of the housing 1, respectively. The bottoms of the two sliders 2111 are slidably connected to slide rails 2112. The sliders 2111 slide on the top of the slide rails 2112, allowing the cutting device to move longitudinally. The transverse sliding assembly 210 includes a slide rail 2101, which is fixedly connected to the top front side of the top plate 208. A slider 2102 is slidably connected to the outer wall of a slide rail 2101. A support plate 2103 is fixedly connected to the front end of the slider 2102. The slider 2102 slides on the top of the slide rail 2101, allowing the cutting device to move laterally. A laser cutter 2104 is fixedly connected to the bottom of the support plate 2103. A ranging component 212 is provided at the bottom of the laser cutter 2104. The ranging component 212 can measure the unevenness of the decal surface. The ranging component 212 includes a connecting plate 2121. The inner side of the connecting plate 2121 is fixedly connected to the lower middle part of the outer wall of the laser cutter 2104. Hydraulic telescopic rods 2122 are fixedly connected to both the left and right sides. The bottom of the hydraulic telescopic rods 2122 is fixedly connected to the same mounting plate 2123.When the mounting plate 2123 passes over uneven surfaces, the hydraulic telescopic rod 2122 drives the sensor 2124 to move upward. Sensors 2124 are installed around the bottom of the mounting plate 2123. A laser generator 6 is fixedly connected to the rear top of the top plate 208. A first reflector frame 7 is fixedly connected to the rear left side of the top of the top plate 208. A second reflector frame 8 is fixedly connected to the front top of the top of the top plate 208. A reflector 9 is fixedly connected to the top of the second reflector frame 8. The laser generator 6 transmits the laser signal to the laser cutter 2104 through refraction for cutting. Limiting grooves 4 are formed on the tops of the two first wedges 207. Tenons 5 are fixedly connected to the bottoms of the two second wedges 209. The outer walls of the two tenons 5 are slidably connected to the inner sides of the corresponding limiting grooves 4.

[0026] Specifically, the device is responsible for precisely cutting the drawing paper. When encountering uneven stacking of the decals or when the material itself has a curvature, the stepper motor 203 starts, driving the worm gear 204 to rotate. The rotation of the worm gear 204 then drives the worm wheel 202. The rotation of the worm wheel 202 causes the moving blocks 205 on both sides to slide in opposite directions. The movement of the moving blocks 205 pushes the first wedge 207 to move to both sides. The first wedge 207 cooperates with the limiting groove 4 and engages with the second wedge 209 and the tenon 5, causing the top plate 208 to move downward. At the same time, the laser cutter 2104 on the front side of the top plate 208 also descends to the cutting point. The laser generator produces laser light, which is transmitted to the laser cutter 2104 through the first mirror frame 7, the second mirror frame 8, and the reflector 9 to cut the decals. As the laser cutter 2104 descends... During the operation, the ranging component 212 begins to function. Before the laser cutter 2104 begins to move and cut, the sensor 2124 at the bottom of the mounting plate 2123 will contact the surface of the decal to sense and measure. When the surface of the decal is uneven or has protrusions, the mounting plate 2123 will retract upward through the hydraulic telescopic rod 2122. At the same time as the sensor 2124 retracts, it sends a command to the stepper motor 203, causing the stepper motor 203 to rotate in the opposite direction. The first wedge 207 lifts the top plate 208 through the second wedge 209. The operation of the stepper motor 203 causes the distance the top plate 208 is lifted to change synchronously with the distance the sensor 2124 retracts, thereby dynamically adjusting the height of the laser cutter 2104 that cuts subsequently. This dynamic adjustment mechanism can compensate for the undulations of the decal surface and effectively avoid missed cuts or overcuts.

[0027] Reference Figure 1 , Figure 2 and Figure 4The adsorption mechanism 3 includes a frame 301. The top left and right sides of the frame 301 are fixedly connected to the bottom of the slide rail 2112, respectively. A cavity 302 is opened in the top of the frame 301. An adsorption plate 303 is fixedly connected to the inner side of the top of the cavity 302. The adsorption plate 303 is used to place the decal. A connecting pipe 304 is connected to the bottom of the frame 301. A negative pressure fan 305 is fixedly connected to the bottom of the connecting pipe 304. The negative pressure fan 305 generates negative pressure inside the cavity 302 through the connecting pipe 304, thereby adsorbing the decal. A dust removal assembly 306 is provided on the right side. The dust removal assembly 306 includes a filter screen 3061, which can filter dust. The outer wall of the filter screen 3061 is fixedly connected to the upper part of the inner wall of the connecting pipe 304. A dust removal port 3062 is opened on the right side of the inside of the frame 301. A cover plate 3063 is provided on the right side of the dust removal port 3062. The cover plate 3063 is closed to prevent the negative pressure effect from being reduced. A hinge 3064 is fixedly connected to the front right end of the cover plate 3063. The cover plate 3063 is rotatably connected to the frame 301 through the hinge 3064.

[0028] Specifically, during the cutting of decals, the decals are first laid flat on the adsorption plate 303. Then, the negative pressure fan 305 is started. The negative pressure generated by the fan acts on the adsorption plate 303 through the connecting pipe 304 and the cavity 302, ensuring that the decals are tightly attached to its surface, thus maintaining stability during cutting and preventing movement, ensuring cutting accuracy. At the same time, the dust and smoke generated during laser cutting are also effectively absorbed, avoiding pollution of the working environment. After entering the cavity 302, the dust is intercepted by the filter screen 3061, preventing it from entering the connecting pipe 304. The operator can open the cover plate 3063 and easily clean the dust in the cavity 302 through the dust removal port 3062 on the left side of the cover plate 3063.

[0029] Working principle: This device cuts drawing paper. When the drawing paper is unevenly stacked or the material has a curvature, the stepper motor 203 is started to drive the worm gear 204 to rotate. The worm gear 204 then drives the worm wheel 202 to rotate. The rotation of the worm wheel 202 causes the moving blocks 205 on both sides to slide in opposite directions. At the same time, the moving blocks 205 drive the wedge block 1 207 to move to both sides. The wedge block 1 207 slides through the limiting groove 4 and the wedge block 209 and tenon 5, causing the top plate 208 to move downward. The laser cutter 2104 on the front side of the top plate 208 also moves downward together. When it reaches the cutting point, the laser generator generates a laser, which is then transmitted to the laser cutter 2104 by the mirror frame 7, mirror frame 2 8 and the reflector 9 to cut the drawing paper. When the laser cutter 2104 moves downward... During the downward movement, the ranging component 212 comes into play. Before the laser cutter 2104 moves to cut, the sensor 2124 at the bottom of the mounting plate 2123 contacts the surface of the decal to sense and measure. When the decal is uneven or protruding, the mounting plate 2123 retracts upward through the hydraulic telescopic rod 2122. At the same time, the sensor 2124 transmits a command to the stepper motor 203 while retracting, causing the stepper motor 203 to start and rotate in the opposite direction. This causes the first wedge 207 to lift the top plate 208 through the second wedge 209. The distance that the stepper motor 203 lifts the top plate 208 changes with the distance that the sensor 2124 retracts, thereby changing the height of the laser cutter 2104 that is cutting subsequently. This dynamically adjusts the height to compensate for surface undulations and avoids missing or overcutting.

[0030] Furthermore, when cutting the decals, the decals are laid flat on the adsorption plate 303, and then the negative pressure fan 305 is started. The negative pressure generated by the negative pressure fan 305 is used to adsorb the decals tightly onto the surface of the adsorption plate 303 through the connecting pipe 304 and the cavity 302, so that the decals will not move during the cutting process and affect the cutting accuracy. The dust and smoke generated by laser cutting are also absorbed to prevent the working environment from being polluted. After the dust enters the cavity 302, it is blocked by the filter screen 3061 and will not enter the interior of the connecting pipe 304. Then, the staff can open the cover plate 3063 to clean the dust inside the cavity 302 through the dust cleaning port 3062 on the left side of the cover plate 3063.
