DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1-Figure 6 A continuous laser marking device shown in the figure includes a machine table 1, a vertical driving mechanism 2, a horizontal driving mechanism 3, and a laser marking machine 4. The middle of the machine table 1 is concave, and bottom boxes 7 are symmetrically arranged at the bottom of the inner side of the machine table 1. Suction tubes 35 are clamped inside the two bottom boxes 7. The suction tubes 35 are in an X shape, and multiple groups of suction holes 36 are opened inside the suction tubes 35. A rolling and flattening component is arranged above the two bottom boxes 7. The vertical driving mechanism 2 is arranged in two groups, and is respectively arranged on both sides of the upper surface of the machine table 1. The horizontal driving mechanism 3 is arranged outside the two groups of vertical driving mechanisms 2. A slide seat 6 is arranged outside the horizontal driving mechanism 3, and the inner side of the slide seat 6 is connected to the laser marking machine 4 through a lifting component.

[0026] The vertical drive mechanism 2, the horizontal drive mechanism 3, and the laser marking machine 4 are all prior arts and will not be described in detail. Setting the suction straw 35 in an X shape can enhance the adsorption capacity of the diagonal and center lines of the leather, thereby improving the positioning effect.

[0027] The rolling and leveling component comprises a slide 37 arranged above the two bottom boxes 7, and rolling components are symmetrically arranged on the front end surface and the rear end surface of the slide 37.

[0028] Both ends of the inner side of the machine 1 are provided with a slide bar 8 and a screw 11. Both ends of the slide bar 8 are connected to the machine 1 through a fixed first mounting plate 9. Both ends of the screw 11 are connected to the machine 1 through a rotatably mounted second mounting plate 10. One end of the screw 11 passes through the outer side of the second mounting plate 10 and the end is connected to a first motor 12. The slide 37 and the slide bar 8 are slidably matched, and the slide 37 and the screw 11 are threadedly matched. The first motor 12 can drive the screw 11 to rotate, and the screw 11 can drive the slide 37 to move, thereby pushing the slide 37 to the top of the bottom box 7 for use when the leather corners are curled.

[0029] The lifting assembly includes a telescopic cylinder 5 arranged on the upper inner side of the slide seat 6. The telescopic end of the telescopic cylinder 5 is fixedly connected to a casing, and the casing is wrapped around the outer side of the laser marking machine 4. The telescopic cylinder 5 drives the casing to drive the laser marking machine 4 to adjust the height, which can not only automatically adjust the distance, but also facilitate the later cleaning of the lens of the laser marking machine 4.

[0030] The rolling assembly includes a support 16 fixedly mounted on the outside of the slide 37, a connecting rod 21 extending from one end of the support 16, a first connecting shaft 18 rotatably inserted on the upper inner side of the connecting rod 21, a push rod 24 fixedly sleeved on the lower outer side of the first connecting shaft 18, a clamping seat 23 extending from the bottom of the push rod 24, a fixing box 29 connected to the inner side of the clamping seat 23 by a fixing bolt 25 connected by a thread, and under the connection between the clamping seat 23 and the fixing bolt 25, the fixing box 29 can be stably set at the lower end of the connecting rod 21, a heating element is arranged on the inner side of the fixing box 29, and a reciprocating flattening element is arranged on the outer wall of the fixing box 29 away from the connecting rod 21, an L-shaped rod 17 is fixedly mounted on the upper surface of the support 16, and the L-shaped rod 17 is close to the first connecting shaft 18. A second connecting shaft 19 is rotatably installed inside the side, and the first connecting shaft 18 and the second connecting shaft 19 are rotatably matched with the L-shaped rod 17. A second motor 22 is arranged at the lower end of the second connecting shaft 19, and the second motor 22 is clamped in the inside of the support 16. A first gear 20 is fixedly sleeved on the outer side of the first connecting shaft 18, and a second gear 38 is fixedly sleeved on the outer side of the second connecting shaft 19. The first gear 20 and the second gear 38 are meshed with each other. Under the connection of the second motor 22, the second connecting shaft 19 can drive the external second gear 38 to rotate, and thus the first gear 20 meshing with the second gear 38 can drive the first connecting shaft 18 to rotate, so the push rod 24 can rotate an angle, thereby adjusting according to the corner position of the leather.

[0031] The heating element includes a heating tube 31 fixedly inserted into the fixed box 29, and connecting seats 30 are fixedly provided at both ends of the outer side of the fixed box 29. Both ends of the heating tube 31 are connected to the corresponding connecting seats 30, and a connecting socket 32 ​​is installed inside one group of the connecting seats 30. The connecting socket 32 ​​can be connected to an external pipeline to meet the heating use of the heating tube 31. The connecting socket 32 ​​is connected to the output end of the heating tube 31. The external rotating sleeve of the heating tube 31 is provided with a heat-conducting sleeve 33. The bottom of the fixed box 29 is provided with a groove for the heat-conducting sleeve 33 to roll. During the movement of the slide 37, the heat-conducting sleeve 33 rolls on the surface of the leather, and then transfers heat to the surface of the leather, thereby reducing the bending hardness of the leather. The groove for the heat-conducting sleeve 33 to roll inside the fixed box 29 can enable the fixed box 29 to move with the heat-conducting sleeve 33 and contact the bent area of ​​the leather, thereby increasing the contact area.

[0032] The reciprocating smoothing member includes a card box 26 fixedly installed on a fixed box 29 and away from one end of the connecting rod 21. A cavity 27 is opened on the inner side of the card box 26. Leveling blocks 28 are slidably arranged at both ends of the cavity 27. Cylinders 15 are arranged at one end of the two leveling blocks 28 away from each other. Under the reciprocating drive of the cylinder 15, the bottom of the two leveling blocks 28 can fit the upper surface of the leather, so as to smooth the leather in the heated area. The ends of the two cylinders 15 away from the leveling blocks 28 are clamped in the card box 26.

[0033] The two suction pipes 35 are both connected and installed with connecting pipes 34. A shelf bin 13 is provided on the upper surface of the machine 1 and on the side away from the horizontal driving mechanism 3. A vacuum negative pressure device 14 is installed inside the shelf bin 13. The two connecting pipes 34 are connected to the inside of the vacuum negative pressure device 14. The vacuum negative pressure device 14 is connected to the corresponding suction port through the connecting pipes 34, so as to meet the use of the suction pipes 35.

[0034] Working principle: When in use, the leather is placed on the upper surface of the two groups of bottom boxes 7, and then the vacuum negative pressure device 14 starts to work. Through the connection of the connecting tube 34, the multiple groups of suction holes 36 inside the X-shaped suction tube 35 are strongly adsorbed on the bottom of the leather. After ensuring that the leather will not move, according to the curling of the leather, the first motor 12 can drive the screw 11 to rotate. Under the limit of the slide bar 8, the slide 37 moves above the bottom box 7. Through the connection of the support 16, during the reciprocating movement of the slide 37, the fixed box 29 corresponding to the upper corner of the bottom box 7 can roll on the corner of the leather. At this time, the heating tube 31 can transfer heat to the heat-conducting sleeve 33. During the movement, the heat-conducting sleeve 33 repeatedly rolls on the corners of the leather. In this way, the hardness of the leather is reduced, so that it is convenient to level the leather. In the heating area, the two groups of cylinders 15 reciprocate and extend, prompting the leveling block 28 at the telescopic end to move back and forth, thereby improving the leveling efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
