[0036] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0037] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a laser engraving device for a cylindrical surface provided by the utility model comprises a frame 1 and a silo 2, a circulating vibration plate feeder 3, a laser engraving platform 4, a laser engraving machine 5 and a material discharge device 6 arranged on the frame 1. The discharge port of the silo 2 is located above the circulating vibration plate feeder 3, the discharge port of the circulating vibration plate feeder 3 is connected to the laser engraving platform 4, and the laser engraving head of the laser engraving machine 5 is located above the laser engraving platform 4. The material discharge device 6 is arranged on the laser engraving platform 4 to push the material out of the laser engraving platform 4.

[0038] During operation, the silo 2 is opened, and the cylindrical material falls into the circulating vibration plate loader 3 from the discharge port of the silo 2. The circulating vibration plate loader 3 vibrates and transports the cylindrical material to the laser engraving platform 4 in a predetermined posture. The laser engraving head of the laser engraving machine 5 performs laser engraving on the cylindrical material located directly below it. After the processing is completed, it is pushed out of the laser engraving platform 4 through the unloading device 6.

[0039] Specifically, the frame 1 is erected on the ground and has a certain structural strength, and is used as the installation base of the laser engraving equipment. The silo 2 is horizontally placed on the table of the frame 1, and a discharge port is provided on one side of the silo 2 close to the circulating vibration plate feeder 3. The discharge port of the silo 2 can be equipped with a pull-out plate for closing or opening the discharge port of the silo 2.

[0040] The present application proposes a preferred implementation mode: a vibrator is installed at the bottom of the silo 2, and with the help of the vibrator, the convenience of the cylindrical material in the silo 2 entering the circulating vibration plate loader 3 through the discharge port of the silo 2 can be improved.

[0041] Further, the circulating vibration disk loader 3 includes a first vibration disk 31, a second vibration disk 32 and a loading track 33. The outer shell of the circulating vibration disk loader 3 surrounds the first vibration disk 31, the second vibration disk 32 and the loading track 33. The bottoms of the first vibration disk 31 and the second vibration disk 32 are respectively provided with vibrators to realize the vibration of the first vibration disk 31 and the second vibration disk 32. The first vibration disk 31 and the second vibration disk 32 are arranged adjacent to each other, the first vibration disk 31 is horizontally arranged below the discharge port of the silo 2, the second vibration disk 32 is gradually raised from the end away from the silo 2 to the end close to the silo 2, and the upper end of the second vibration disk 32 is connected to the loading track 33. The vibration direction of the first vibration disk 31 is to vibrate from the end close to the silo 2 to the end away from the silo 2. The vibration direction of the second vibration disk 32 is to vibrate from the end away from the silo 2 to the end close to the silo 2.

[0042] Furthermore, the direction of the feeding track 33 is to bypass the end of the first vibration disk 31 close to the silo 2 from the upper end of the second vibration disk 32, and bypass the side of the first vibration disk 31 away from the second vibration disk 32 to connect with the laser carving platform 4. The feeding track 33 includes an arc segment 331 and a straight segment 332, the arc segment 331 is connected to the straight segment 332, and the straight segment 332 is connected to the laser carving platform 4. The arc segment 331 of the feeding track 33 includes an arc plate 34, and the arc plate 34 bypasses the end of the first vibration disk 31 close to the silo 2 from the upper end of the second vibration disk 32, and goes around to the side of the first vibration disk 31 away from the second vibration disk 32. One end of the arc plate 34 is tightly connected to the peripheral shell of the circulating vibration disk loader 3, and the other end of the arc plate 34 extends to the straight segment 332, and the end of the arc plate 34 extending to the straight segment 332 is connected to the peripheral shell of the circulating vibration disk loader 3 through the gap adjustment component 7. The bottom surface of the arc section 331 of the feeding track 33 gradually slopes downward along the direction of the arc plate 34 from the side close to the lifting end of the second vibration plate 32 to the side away from the lifting end of the second vibration plate 32 .

[0043] During operation, the cylindrical material falls onto the first vibration plate 31 through the discharge port of the silo 2. The first vibration plate 31 vibrates and transports the cylindrical material in a direction away from the silo 2. When the cylindrical material moves to the second vibration plate 32, the second vibration plate 32 moves the cylindrical material in a direction close to the material layer and lifts it. Then, the cylindrical material enters the arc section 331 of the feeding track 33, and then the cylindrical material enters the straight section 332 of the feeding track 33. Under the action of the motors under the first vibration plate 31 and the second vibration plate 32, the cylindrical material moves along the direction of the feeding track 33 to the laser engraving platform 4.

[0044] It should be noted that the heights of the second vibration plate 32 and the feeding track 33 are greater than the first vibration plate 31. When there are too many cylindrical materials on the second vibration plate 32 and the feeding track 33, they can fall onto the first vibration plate 31 to achieve cyclic feeding. The feeding track 33 has a screening effect on the posture of the material. The gap adjustment component 7 is used to adjust the passing gap of the straight segment 332 so that the passing gap of the straight segment 332 allows the diameter of the cylindrical material to pass through but does not allow the length of the cylindrical material to pass through. In this way, the cylindrical material can enter the straight segment 332 of the feeding track 33 with its length direction parallel to the length direction of the straight segment 332.

[0045] A feasible implementation of the gap adjustment component 7 is: the gap adjustment component 7 includes a connecting rod 71 and a fixing nut 72, one end of the connecting rod 71 is tightly connected to the peripheral shell of the circulating vibration plate loader 3, the arc plate 34 extends to one end of the straight section 332 and penetrates into the connecting rod 71 and slides with it, and a fixing nut 72 is respectively arranged on both sides of the arc plate 34, and the two fixing nuts 72 are threadedly connected to the connecting rod 71.

[0046] When the clearance of the straight section 332 needs to be adjusted, the position of the arc plate 34 on the connecting rod 71 can be adjusted by rotating the two fixing nuts 72 , thereby achieving the adjustment of the clearance of the straight section 332 .

[0047] Furthermore, a guide rail 41 is provided on the laser engraving platform 4, and the guide rail 41 connects the discharge port of the circulating vibration plate feeder 3 and the laser engraving station 42 located directly below the laser engraving head. Specifically, the length of the guide rail 41 is parallel to the length of the straight section 332 of the feeding rail 33, and the guide rail 41 is connected to the straight section 332 of the feeding rail 33. After the cylindrical material passes through the straight section 332 of the feeding rail 33, it can enter the guide rail 41, and enter the laser engraving station 42 located directly below the laser engraving head under the guidance of the guide rail 41.

[0048] More specifically, a sensor is provided on the bottom plate of the laser engraving station 42. When the cylindrical material moves to the laser engraving station 42, the sensor is triggered, the laser engraving starts after a delay, and the material is pushed out by the unloading device 6 after another delay, and a new material is fed in, and the cycle continues.

[0049] More specifically, the unloading device 6 includes a telescopic cylinder 61 and a follower block 62. The cylinder body of the telescopic cylinder 61 is fixedly mounted on the frame 1. The movement direction of the telescopic cylinder 61 is perpendicular to the length direction of the guide rail 41. The follower block 62 is fixedly connected to the movable end of the telescopic cylinder 61, and the follower block 62 extends to the laser engraving station 42. When the telescopic cylinder 61 is in a retracted state, the follower block 62 is located on one side of the laser engraving station 42. When the laser engraving is finished, the telescopic cylinder 61 extends and drives the follower block 62 to move and push the processed cylindrical material from the other side of the laser engraving station 42 to the laser engraving platform 4. Preferably, a unloading guide plate 8 is provided on either side of the laser engraving station 42. With the help of the unloading guide plate 8, the damage to the cylindrical material during unloading can be reduced.

[0050] It should be further explained that, preferably, the laser engraving platform 4 is tilted on the frame 1, and the tilt direction of the laser engraving platform 4 is tilted downward from the side where the material unloading guide plate 8 is located. During laser engraving, the follower block 62 is located at the lower side of the laser engraving station 42, which can keep the cylindrical material stable on the laser engraving station 42. After the laser engraving is completed, the telescopic cylinder 61 drives the follower block 62 to move upward and push the cylindrical material that has been laser engraved out of the laser engraving platform 4.
