When the upper surface of the arc plate 1203 is in contact with the rubber sleeve 5, a part of the space will be left for the engraving head 18 to engrave.

[0031] like Figures 6 to 8As shown, the protection device 14 includes two fixed plates 1401, a transmission wheel 1402 is rotatably connected between the two fixed plates 1401, a friction ring 1403 is fixedly connected to the right side of the transmission wheel 1402, a take-up rod 1404 is rotatably connected to the inner surface of the friction ring 1403, a connecting rope 1405 is fixedly connected to the surface of the take-up rod 1404, a support block 1406 is fixedly connected to the rear side of the linkage block 13, and a fixing column 1407 is fixedly connected to the top of the support block 1406 The top left side of the fixed column 1407 is fixedly connected to a magnet 16, the other end of the connecting rope 1405 is fixedly connected to a protective plate 1408, and the bottom left side of the protective plate 1408 is fixedly connected to a spring 1409; a plurality of flexible particle protrusions are provided at the rotation connection between the take-up rod 1404 and the friction ring 1403, so that the friction ring 1403 can drive the take-up rod 1404 to rotate together, and when the take-up rod 1404 stops rotating, the friction ring 1403 can also rotate on the take-up rod 1404, When the engraving head 18 is working, the rotation of the rubber sleeve 5 will drive the transmission wheel 1402 to rotate, the rotation of the transmission wheel 1402 will drive the friction ring 1403 to rotate, the rotation of the friction ring 1403 will drive the take-up rod 1404 to rotate, when the take-up rod 1404 tightens the connecting rope 1405, the protection plate 1408 is limited by the arc frame 1201, when the connecting rope 1405 is tightened, the take-up rod 1404 stops rotating, and the friction ring 1403 rotates on the surface of the take-up rod 1404, so that the connecting rope 1405 It is always in a tightened state, and the protection plate 1408 will be pulled to the edge. When the rubber sleeve 5 gets stuck, the friction ring 1403 will stop rotating, and the connecting rope 1405 will pull and rotate the take-up rod 1404 under the action of the spring 1409. The spring 1409 will pull back the protection plate 1408 to block the laser, so that the laser will no longer perform laser engraving on the same position on the rubber sleeve 5, protecting the product from damage. At the same time, the laser is turned off to continue working, reducing the possibility of harm.

[0032] like Fig. 9 As shown, the collecting device 15 includes a connecting rod 1501, a chip guard plate 1502 is fixedly connected to the rear side of the connecting rod 1501, a chip storage groove 1503 is opened on the right side of the chip guard plate 1502, and a collecting baffle 1504 is fixedly connected to the bottom of the chip storage groove 1503; when the engraving head 18 is engraving the rubber sleeve 5, debris will be generated, and the user can continuously blow air at the chip guard plate 1502 through the blowing port 1204 so that the generated debris is blown into the chip storage groove 1503 during the falling process, and is blocked by the collecting baffle 1504 and will not scatter out, thereby reducing the time for the user to clean the device.

[0033] like Figures 6 to 10As shown, a telescopic frame 17 is fixedly connected to the left side of the box body 1. The telescopic frame 17 is a hydraulic telescopic mechanism that can achieve its own extension and shortening. An engraving head 18 is fixedly connected to the output end of the telescopic frame 17, and a second magnet 19 is fixedly connected to the right side of the engraving head 18; the telescopic frame 17 can drive the engraving head 18 to move horizontally, so that the engraving head 18 can work at different positions. At the same time, the second magnet 19 is used to be adsorbed and connected with the first magnet 16, so that the whole device can be more linked and convenient for subsequent processing.

[0034] like Fig.11 As shown, the clamping device 6 includes a clamping box 601, one side of the inside of the clamping box 601 is rotatably connected to an electric gear 602, the electric gear 602 is meshingly connected to a toothed plate 603, and one end of the toothed plate 603 is rotatably connected to a limiting roller 604; it is energized through the wiring port 7 and the external wires, and the toothed plate 603 is driven to move by the rotation of the electric gear 602 to limit the rubber sleeve 5, so that the rubber sleeve 5 can rotate stably without shaking, thereby reducing the misalignment of the laser engraving area, thereby improving the qualified rate of the product.

[0035] like Figures 3 to 6 As shown, the inner surfaces of the arc frame 1201 and the arc plate 1203 are in contact with the surface of the rubber sleeve 5, and the upper surface of the transmission wheel 1402 is at the same level as the bottom of the inner surface of the arc frame 1201; the arc frame 1201 and the arc plate 1203 are made of flexible materials and will not damage the rubber sleeve 5 when moving. The upper surface of the transmission wheel 1402 is at the same level as the bottom of the inner surface of the arc frame 1201, which can ensure that the transmission wheel 1402 can rotate together with the rubber sleeve 5.

[0036] like Fig.11 As shown, the surface of the limiting roller 604 abuts against the rubber sleeve 5, and the rotation of the rubber sleeve 5 drives the limiting roller 604 to rotate, thereby limiting the rubber sleeve 5, so that the clamping device 6 reduces friction loss when the rubber sleeve 5 rotates.

[0037] like Figures 6 to 10 As shown, the magnet 1 16 and the magnet 2 19 have opposite magnetic properties and can attract and fit each other. The movement of the magnet 2 19 will drive the magnet 1 16 to move. When the magnet 1 16 and the magnet 2 19 are adsorbed together, the engraving head 18 can move, driving the protection device 14 and the collection device 15 to move together.

[0038] Working principle: When the user uses the device, first install the rubber sleeve 5 on the device, prepare for engraving, fix the rubber sleeve 5 through the clamping device 6, and energize the external wire through the wiring port 7. The electric gear 602 rotates to drive the tooth plate 603 to move, so as to limit the rubber sleeve 5, so that the rubber sleeve 5 can rotate stably without shaking, and the misalignment of the laser engraving area is reduced, thereby improving the qualified rate of the product. After that, the position of the engraving head 18 can be adjusted to move to the top of the arc frame 1201. At this time, the electric push rod 8 is started, and the electric push rod 8 moves the telescopic box 9 and other parts upward. When it rises to a certain height, the magnet 16 and the magnet 2 19 will be in contact. They attract each other and connect. At the same time, the arc frame 1201 and the arc plate 1203 are not semicircular plates. When the upper surface of the arc plate 1203 fits with the rubber sleeve 5, a part of the space will be left for the engraving head 18 to engrave. When the magnet 16 and the magnet 2 19 are adsorbed together, the hydraulic slide rail 1202 can be started to rotate the arc plate 1203 with the axis of the rubber sleeve 5 as the axis of rotation, and the arc plate 1203 is completely consistent with the outer surface of the hydraulic slide rail 1202, and a semi-closed ring can be formed after the rotation is completed, completing the auxiliary limiting of the rubber sleeve 5. At the same time, the air outlet 1204 on the arc frame 1201 and the arc plate 1203 can clean the surface of the rubber sleeve 5 to ensure that dust and debris will not appear in the subsequent engraving. The engraving head 18 can be moved to a fixed position for engraving. At the same time, the protection device 14 and the collecting device 15 will move to the position of the engraving head 18. The rotation connection between the wire take-up rod 1404 and the friction ring 1403 is provided with a plurality of flexible particle protrusions. The particle protrusions are made of silicone rubber or other materials with good wear resistance, so that the friction ring 1403 can drive the wire take-up rod 1404 to rotate together. When the wire take-up rod 1404 stops rotating, the friction ring 1403 can also rotate on the wire take-up rod 1404. When the engraving head 18 is working, the rotation of the rubber sleeve 5 will drive the transmission wheel 1402 to rotate, the rotation of the transmission wheel 1402 will drive the friction ring 1403 to rotate, and the rotation of the friction ring 1403 will drive the wire take-up rod 140 4 rotates. When the take-up rod 1404 tightens the connecting rope 1405, the protection plate 1408 is limited by the arc frame 1201. When the connecting rope 1405 is tightened, the take-up rod 1404 stops rotating, and the friction ring 1403 rotates on the surface of the take-up rod 1404, so that the connecting rope 1405 is always in a tightened state, and the protection plate 1408 is also pulled to the edge. When the rubber sleeve 5 is stuck, the friction ring 1403 stops rotating, and the connecting rope 1405 pulls and rotates the take-up rod 1404 under the action of the spring 1409. The spring 1409 pulls back the protection plate 1408 to block the laser, so that the laser no longer performs laser engraving on the same position on the rubber sleeve 5, thereby protecting the product from damage.At the same time, the laser is turned off and the work is continued, which reduces the possibility of harm. When the engraving head 18 is engraving the rubber sleeve 5, debris will be generated. The user can blow air continuously at the chip baffle plate 1502 through the air port 1204 so that the generated debris will be blown into the chip storage groove 1503 during the falling process, and will be blocked by the collection baffle plate 1504 and will not be scattered out, thus reducing the time for the user to clean the device.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
