[0027] The working principle of the present application is: before operation, the device first completes the initial state calibration, motor one 129 drives synchronous belt one 1211 to operate, four groups of synchronous wheels one 125 drive screw 123 to rotate synchronously, moving block 124 drives cutting table 13 to rise to the preset initial position along guide rod 121, spring 22 of material receiving part 2 is in a natural stretched state, pushing material receiving plate 21 is inserted into material falling groove 132, at this time, the top end of material receiving plate 21 is accurately flush with the bottom end of the inside of limiting groove 131, forming a flat plate supporting surface, the bottom end of rotating cylinder 32 of limiting part 3 is higher than the top end of inserting rod 36, the clamping block 33 part extends into the below of material falling groove 132, forming rigid support for the bottom end of material receiving plate 21, avoiding its downward movement under stress, the operator puts the mold steel plate blank to be cut into the limiting groove 131, then the operator imports the cutting parameters of the plate to be processed through the control system, including cutting track, laser power, cutting speed and X / Y axis moving stroke, etc., the system automatically retrieves the corresponding parameter library, completes the parameter preset before cutting, after feeding is completed, motor one 129 is started again, through the transmission effect of synchronous belt one 1211, four groups of screw 123 are driven to rotate synchronously, cutting table 13 stably rises and falls along guide rod 121, until the upper surface of the plate to be cut reaches the best focusing height of laser cutting head 17, in this process, the sliding cooperation of four groups of guide rods 121 and sliding blocks one 122 provides stable guidance for cutting table 13, avoiding inclination in the lifting process, the convex letter shape structure formed by synchronous belt one 1211 and guide wheel 128 cooperates with the avoiding groove 111 of mounting frame 11, effectively avoiding the interference between the transmission components and mounting frame 11, ensuring the lifting precision, at the same time, motor two 143 of Y-axis linear driver 14 is started, synchronous belt two 146 is driven to rotate through synchronous wheel three 144 and synchronous wheel four 145, sliding block two 142 moves along slide rail 141, driving mounting rod 15 and X-axis linear driver 16 to move along Y-axis direction as a whole, then motor two 143 of X-axis linear driver 16 is started, through the same synchronous belt transmission structure, driving laser cutting head 17 to move along X-axis direction, finally making laser cutting head 17 accurately move to the starting point of cutting track, completing the track positioning before cutting, after positioning is completed, laser cutting head 17 is started, and the operation according to the preset cutting track is started, in the cutting process, X-axis and Y-axis linear driver 14 continuously cooperate and operate, through the accurate transmission of synchronous belt two 146, driving laser cutting head 17 to move along the preset track stably, the I-shaped distribution of two groups of Y-axis linear driver 14 and X-axis linear driver 16 ensures that the cutting track covers the whole cutting area of material falling groove 132, the finished plate produced in the cutting process directly falls on the material receiving plate 21 below, at this time, the clamping block 33 of limiting part 3 always limits the material receiving plate 21, avoiding the downward movement of material receiving plate 21 due to the weight of the plate, ensuring the stability of the plate supporting surface in the cutting process, after a group of plate cutting is completed, motor one 129 is reversed, driving cutting table 13 to slowly move downward along guide rod 121, at this time, rotating cylinder 32 moves downward synchronously with cutting table 13,When the slot 34 of the rotating cylinder 32 is aligned and contacted with the insertion rod 36 of the mounting frame 11, the insertion rod 36 gradually inserts into the slot 34. Due to the spiral guide groove on the inner side of the slot 34 and the spiral guide block on the outer side of the insertion rod 36, the downward pressure of the cutting table 13 drives the rotating cylinder 32, the rotating shaft 31 and the clamping block 33 to rotate synchronously, so that the clamping block 33 gradually moves out from below the material falling groove 132, and the limiting of the material receiving plate 21 is released. After the limiting is released, the material receiving plate 21 starts to move downward along the material falling groove 132 under the weight of the upper cutting finished product, and at the same time, the four groups of springs 22 are compressed. During the downward movement, the material receiving plate 21 first contacts the rounded corner at the top end of the limiting plate 25, and then is accurately inserted between the two limiting plates 25 under the guidance of the rounded corner arc surface. The two sides of the material receiving plate 21 are tightly fitted with the inner side of the limiting plate 25, so as to avoid inclination deviation during the downward movement. When the material receiving plate 21 moves downward to a certain stroke, one side of the material receiving plate 21 contacts the top rounded corner surface of the top plate 26 of the bottom plate 23. Under the support of the rounded corner surface, the material receiving plate 21 gradually forms an inclination angle. At this time, the finished plate on the material receiving plate 21 smoothly slides out of the area of the bottom plate 23 under the action of its own gravity and the inclined surface guidance, and falls into the pre-set finished product collecting frame, completing the automatic material discharge. After the finished product is discharged, the pressure on the material receiving plate 21 disappears, and the four groups of springs 22 gradually stretch under the elastic restoring force, pushing the material receiving plate 21 to reset upward. At the same time, the motor 129 rotates forward, driving the cutting table 13 to rise, and the rotating cylinder 32 rises synchronously with the cutting table 13. The insertion rod 36 gradually separates from the slot 34. The rotating cylinder 32 reversely rotates under the action of its own gravity and the resetting thrust of the spring 22, so that the clamping block 33 rotates again to below the material falling groove 132. When the material receiving plate 21 is completely reset and inserted into the material falling groove 132, the clamping block 33 again limits the material receiving plate 21, and the device returns to the initial state. Then, the operator can perform the next round of feeding, or the device can be connected to the automatic feeding mechanism to complete continuous feeding, start the next round of cutting cycle, and realize the automatic processing of batch mold plate materials. Through the sliding cooperation of the material receiving plate 21 of the receiving part 2 and the material falling groove 132, a flat support reference can be provided for the to-be-cut plate, ensuring the consistency of the cutting size. The elastic structure of the four groups of springs 22 can realize the automatic resetting of the material receiving plate 21, saving the tedious steps of manual resetting. The rounded corner design of the limiting plate 25 effectively avoids the inclination of the material receiving plate 21 during the downward movement, ensuring the stability of the receiving. The rounded corner surface of the top plate 26 realizes the automatic material discharge of the plate by means of gravity, greatly improving the continuity and automation degree of the mold plate cutting. The clamping block 33 of the limiting part 3 limits the material receiving plate 21, which can avoid the downward movement of the material receiving plate 21 due to the weight of the plate during the cutting process, ensuring the flatness of the cutting area and improving the cutting precision. The spiral guide structure of the insertion rod 36 and the slot 34 is realized by the downward movement of the cutting table 13, which realizes the automatic unlocking of the clamping block 33 without additional driving components, simplifies the equipment structure and reduces the failure probability. The connection mode of the T-shaped rotating shaft 31 ensures the stability of the rotation of the rotating cylinder 32 and the clamping block 33, making the limiting and unlocking actions accurate and reliable.

Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
