[0002] An engraving machine is a device that uses computer numerical control (CNC) technology to control a tool or drill to cut or engrave materials. After the user designs or selects the desired pattern or model on a computer, the design file is transferred to the engraving machine's control system, which then precisely guides the cutting tool to cut or engrave the workpiece. For example, patent number CN101879727B, titled "A Mortise Engraving Machine," discloses a machine platform with a left convex portion on the left side of its front end and a right convex portion corresponding to the left convex portion on the right side of its front end. A groove is formed between the front end of the machine platform and the left and right convex portions, and a positioning portion is provided on the front end of the machine platform. Furthermore, the machine platform is equipped with an inverted U-shaped hanger that can move parallel to the machine platform and forward and backward. The hanger is equipped with a tool holder that can slide left and right relative to the hanger. A tool is located below the tool holder. This engraving operation is common in most existing engraving machines. However, this device cannot automatically load and unload materials; manual operation is required to push a plate to a designated operating area for loading. This lacks automation and hinders factory production efficiency. Utility Model Content

[0031] The present invention will be further described with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 5The utility model shows an automatic loading and unloading engraving machine, comprising a machine table 1, on which is mounted an engraving machine body 2 capable of engraving along the three-dimensional direction of the machine table 1. It should be noted that the engraving machine body 2 in this solution adopts equipment that can be purchased on the market in the prior art, and since the improvement point of this solution itself does not lie in the engraving machine body 2, it is not described in detail in the description. It is only necessary to select an existing engraving machine device that meets the technology, or it can be an engraving machine with patent number CN101879727B; the feeding front end of the machine table 1 is provided with a feeding component 4 The feeding assembly 4 includes a support frame 41 longitudinally mounted on the machine table 1, and a clamping plate 42 is installed on the support frame 41. The two clamping plates 42 form a group of clamping parts. Two parallel limiting columns 46 are adjustable and locked on one clamping plate 42. The distance between the two limiting columns 46 is the length of the plate 5 to be processed. The two clamping plates 42 on the support frame 41 are adjustable in spacing. The distance between the two clamping plates 42 is the width of the plate 5 to be processed. Two auxiliary brackets 14 are provided on the machine table 1. The auxiliary bracket 14 is arranged below the clamping plate 42 and is used to support the plate 5 to be processed. The plate 5 is pushed to the operating area 13; the machine table 1 is provided with an adjusting pushing assembly 3 for pushing the plate 5 to be processed in the feeding assembly 4 to the operating area 13, the adjusting pushing assembly 3 includes a first cylinder 31 arranged at the front end of the feeding assembly 4, the first cylinder 31 is set with a first piston rod 32 in the direction of the operating area 13, the moving end of the first piston rod 32 is installed with a pushing plate 37, the pushing plate 37 is arranged between the two auxiliary brackets 14, and the height is lower than the height of the two auxiliary brackets 14, the end of the pushing plate 37 is installed with a flip-up and rebounding pressing block 33, the pressing block 3 3 is not higher than the thickness of a sheet material 5 to be processed and is not lower than the height of the auxiliary bracket 14; when in use, the pressing block 33 pushes the sheet material 5 to be processed forward one by one; a second cylinder 34 is provided on the side opposite to the first cylinder 31, and a top block 36 is provided at the movable end of the second piston rod 35 of the second cylinder 34; during processing, the top block 36 and the pressing block 33 jointly clamp the sheet material 5 to be processed in the operating area 13; a discharge slot 12 is provided at the feeding end of the machine table 1, the opening area of ​​the discharge slot 12 is larger than the area of ​​the sheet material 5 to be processed, and a conveyor belt 6 is provided below the discharge slot 12.

[0033] At least two groups of clamping parts are provided on the support frame 41, and two engraving machine bodies 2 are provided on the machine table 1 to match the two groups of clamping parts respectively. Multiple groups of parallel clamping parts and multiple matching engraving machine bodies 2 are set to improve the processing efficiency. It should be noted here that whether there are two or more engraving machine bodies 2, they are all controlled by the same set of mobile equipment, so the displacement is synchronized during movement.

[0034] An adjustment slot 43 is provided on the clamping plate 42, and the two limit columns 46 are adjustably locked on the adjustment slot 43 by means of a set screw 44. The adjustment slot 43 is provided with at least two upper and lower ones, which enables the limit columns 46 to be more stably installed on the limit slot 43. And since the limit columns 46 are installed by means of a set screw 44, they can be adjusted according to the length of the plate 5 to be processed, and the adaptability is higher.

[0035] The support frame 41 is provided with more than two cross beams 45 perpendicular to the moving direction, and the cross beams 45 are provided with slide grooves. The edges of the clamping plates 42 are I-shaped and are inserted into the slide grooves to slide. When in use, the positions of the two clamping plates 42 are adjusted and then locked and positioned by external screws. This setting is the same as the above principle, that is, it can be adjusted according to the width of the plate 5 to be processed, so that it is more adaptable, and the clamping plates 43 are inserted into the slide grooves for movement, are not easy to fall off, and also have positioning properties.

[0036] The end of the pushing plate 37 is fixedly connected to one end of the connecting block 39, and the other end of the connecting block 39 is hinged to the pressing block 33. The height of the pressing block 33 is higher than the height of the pushing plate 37. An obliquely installed connecting spring 38 is provided between the pushing plate 37 and the pressing block 33. The top of one end of the pressing block 33 facing the pushing plate 37 is set with an arc chamfer. By setting the connecting spring 38, the pressing block 33 can be pressed down when resetting and then elastically restored to an upright state when returning to the initial position to push the next sheet 5 to be processed. Setting the top of the pressing block 33 to a circular arc chamfer can facilitate the pressing block 33 to be smoothly pulled out from under the sheet 5 to be processed and avoid damage to its bottom surface.

[0037] The connecting bracket 61 at the edge of the conveyor belt 6 is obliquely installed on the support plate 11 below the machine platform 1 , and the conveyor belt 6 is driven by a driving motor 62 .

[0038] A material guide inclined plate 71 is provided below the discharge slot 12 of the machine 1. The material guide inclined plate 71 is inclinedly arranged above the conveyor belt 6. The material guide inclined plate 71 is welded into one with the mounting bracket 7. The mounting bracket 7 is fixed on the support plate 11. The material guide inclined plate 71 can allow the processed plates to fall onto the conveyor belt 6 in an orderly and smooth manner.

[0039] The horizontal height of the operating area 13 is flush with the horizontal height of the auxiliary bracket 14, which is convenient for pushing. It should be noted that in order to make the movement of the pressing block 33 smoother, the operating area 13 is set as two like the auxiliary bracket 14, which can also be understood as a split setting.

[0040] In actual work, first lock the limit column in the adjustment groove by the set screw. At this time, the distance between the two limit columns is the length of the plate to be processed. Then push the clamping plate onto the crossbeam of the support frame, engage with the edge through the slide groove, and then push it in the slide groove. By moving the width of the clamping plate, the distance between the two clamping plates is made to be the width of the plate to be processed. Then use the screw to lock the position of the clamping plate, and then feed the plate to be processed from top to bottom into a set of clamping parts. In this way, the early operation process is realized. After that, only the machine is needed to realize loading and unloading, and there is no need for manual pushing and feeding.

[0041] Then the loading operation is started, the first cylinder drives the first piston rod to move, and the pushing plate on the first piston rod drives the pressure block to move toward the operating area, and the pressure block pushes the plate to be processed piece by piece. Since the plate to be processed is also set on the auxiliary brackets on both sides, the pressure block only plays a pushing role. After the pressure block pushes the plate to be processed to the operating area, the second cylinder on the opposite side of the first cylinder is started, and the second cylinder drives the second piston rod to push the top block, so that the top block cooperates with the pressure block in the operating area to press the plate to be processed, and then the engraving machine body is turned on, and the engraving machine body moves in the corresponding direction according to the instructions of the controller. Carving is carried out in the area. After the engraving is completed, the engraving machine returns to the original Z-axis height, the second cylinder closes the top block and no longer presses the plate, and then the first cylinder is closed, and the push block drives the pressure block to reset and retract. Since the pressure block and the push block are hinged and connected by a connecting spring, they are pressed downward by the plate to be processed at the rear end when retracting. Finally, after going around the plate to be processed, they return to their original upright state due to elasticity, and are then driven forward by the first cylinder to push the next plate to be processed. It should be noted that the height of the pressure block shall not exceed the thickness of a plate to be processed to avoid being affected during the piece-by-piece operation;

[0042] When the plate is processed and stays in place, the first cylinder pushes the pressing block again to transport a new plate to be processed to the operation area. The processed plate is pushed into the discharge slot, and the new plate to be processed continues to be engraved. The processed plate gradually falls onto the conveyor belt along the guide inclined plate below the discharge slot, and is then sent out through the conveyor belt, thereby realizing automatic loading and unloading operations, and multiple steps can be carried out simultaneously without affecting each other, which greatly reduces the operation time and improves the level of factory automation.

[0043] The contents not described in detail in this specification belong to the prior art known to professionals in this field.

[0044] The above-described embodiments merely represent preferred embodiments of the present invention, and their descriptions are relatively specific and detailed. However, the present invention is not limited to these embodiments. It should be noted that any improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
