Description

Technical Field

[0001] This utility model belongs to the field of laser marking technology, specifically relating to a flexible label laser marking machine. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus engraving exquisite patterns, trademarks, and text. Laser marking machines are mainly used in applications requiring higher precision and finer details, such as electronic components, integrated circuits, electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.

[0003] Problems with existing technology:

[0004] Currently available flexible label laser marking machines suffer from several drawbacks. Due to the softness of the labels and the lack of winding and tension adjustment functions, the labels are prone to wrinkling, affecting the marking quality. Furthermore, existing flexible label laser marking machines cannot simultaneously perform die-cutting on the marked labels, requiring external equipment and thus impacting the overall efficiency of label marking. Utility Model Content

[0005] The purpose of this invention is to provide a flexible label laser marking machine that, through the coordinated operation of a winding mechanism, an unwinding mechanism, and a die-cutting mechanism, achieves high-quality marking of flexible labels, simultaneously performs die-cutting and removal of the labels, and can also wind up excess flexible label tape, thereby improving the overall efficiency of laser marking.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A flexible label laser marking machine includes a base plate, on the top of which a frame is fixedly mounted;

[0008] A support mechanism is fixedly installed on the top of the frame. The support mechanism drives the laser marking mechanism to move vertically. A die-cutting mechanism is provided on one side of the support mechanism, and a winding mechanism is provided on one side of the frame.

[0009] The winding mechanism includes a bracket, a first motor, and a first lead screw. A material roller is rotatably mounted on the top of the bracket, and a gantry is fixedly mounted on one side of the bracket via a fixing frame. The first motor drives the first lead screw to rotate, causing the second mounting seat to drive the second pressure roller to move vertically.

[0010] The frame is rotatably mounted on both sides, and a second motor is fixedly installed inside one side of the frame. The second motor drives the second lead screw to drive the connecting block through thread transmission, so that the connecting block drives the winding mechanism to move linearly.

[0011] The bracket is slidably installed on the base plate, and the fixing frame is fixedly connected between the connecting block and the bracket.

[0012] The first lead screw is rotatably installed inside the gantry, and the first lead screw is threadedly installed on the second mounting base. The second pressure roller is rotatably installed on the second mounting base. The winding mechanism and the unwinding mechanism have the same structure and are arranged in a mirror image on both sides of the frame.

[0013] The die-cutting mechanism includes a frame and a first pressure roller. A lifting screw is rotatably installed inside the frame. The lifting screw drives the first mounting seat to move vertically, causing the first pressure roller to move to the top of the die-cutting mold. The die-cutting mold is fixedly installed inside the discharge cavity.

[0014] The discharge chamber is located inside the frame, and the frame is located on both sides of the top of the discharge chamber and is fixedly installed with the frame. There are two first mounting seats, and the first pressure roller is rotatably installed between the first mounting seats.

[0015] The support mechanism includes a base, a fixed seat, and a slider. The base is hinged to the top plate via a scissor brace, and an adjusting screw is rotatably mounted on one side of the fixed seat.

[0016] The fixed seat is fixedly installed on the base, the scissor brace is hinged to the slider, the slider is threadedly installed on the adjusting screw, and is slidably installed on the fixed seat.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention utilizes a bracket mounted on the top of a base plate, with a material roller mounted on top of the bracket. This material roller can rewind waste flexible label tape. A gantry is mounted on top of the fixed frame, and a first motor is mounted on top of the gantry. When the first motor drives the first lead screw to rotate, it drives the second mounting base to move vertically, causing the second pressure roller to move synchronously. Therefore, under the combined action of the support roller, the second pressure roller, and the fixed frame, the tension of the second pressure roller can be adjusted vertically, thus enabling adjustment of the tension during the rewinding process. Similarly, the unwinding mechanism has the same structure as the rewinding mechanism, so the tension can also be adjusted during the unwinding process to prevent the flexible label tape from being too loose and affecting the marking quality.

[0019] This invention features a discharge chamber installed inside the frame, with a die-cutting mold fixedly mounted inside. A frame is mounted on the top of the frame on one side of the winding mechanism, and a lifting screw is rotatably mounted inside the frame. Rotating the lifting screw causes the first mounting base to move vertically, which in turn causes the first pressure roller to move synchronously, pressing the marked label against the die-cutting mold. The label is then die-cut by the blades on the die-cutting mold's surface. Therefore, this device can simultaneously die-cut labels without requiring additional equipment for label separation, thus improving label marking efficiency. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-5As shown, a flexible label laser marking machine includes a base plate 1, and a frame 2 is fixedly installed on the top of the base plate 1;

[0029] A support mechanism 3 is fixedly installed on the top of the frame 2. The support mechanism 3 drives the laser marking mechanism 4 to move vertically. A die-cutting mechanism 6 is provided on one side of the support mechanism 3, and a winding mechanism 7 is provided on one side of the frame 2.

[0030] The winding mechanism 7 includes a bracket 71, a first motor 75, and a first lead screw 76. A material roller 72 is rotatably mounted on the top of the bracket 71, and a gantry 74 is fixedly mounted on one side of the bracket 71 through a fixing frame 73. The first motor 75 drives the first lead screw 76 to rotate, causing the second mounting seat 77 to drive the second pressure roller 78 to move vertically.

[0031] See attached document Figure 1 and Figure 3 In this embodiment, rollers 5 are rotatably mounted on both sides of the frame 2, and a second motor 10 is fixedly installed inside one side of the frame 2. The second motor 10 drives the second lead screw 11 to drive the connecting block 9 through threaded transmission, so that the connecting block 9 drives the winding mechanism 7 to move linearly.

[0032] In the above embodiment, the second lead screw 11 can be rotated inside the frame 2 by starting the second motor 10. Since the connecting block 9 is threadedly installed with the second lead screw 11, and one side of the connecting block 9 is fixedly connected to the winding mechanism 7 and the unwinding mechanism 8 respectively, the winding mechanism 7 and the unwinding mechanism 8 can be linearly adjusted on the top of the base plate 1 when the second motor 10 is started.

[0033] Specifically, by adjusting the winding mechanism 7 and the unwinding mechanism 8, this device can be adapted to the marking of flexible labels of different widths.

[0034] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, the bracket 71 is slidably installed on the base plate 1, and the fixing frame 73 is fixedly connected between the connecting block 9 and the bracket 71.

[0035] In the above embodiment, since the fixed frame 73 is fixedly connected to the connecting block 9 and the fixed frame 73 is fixedly connected to the bracket 71, when the second lead screw 11 drives the connecting block 9 to rotate, the bracket 71 can slide on the top of the base plate 1, thereby driving the material roller 72 to move synchronously. Similarly, since the winding mechanism 7 and the unwinding mechanism 8 have the same structure and are arranged in a mirror image on both sides of the frame 2, the unwinding mechanism 8 can also achieve synchronous adjustment in the same way.

[0036] Furthermore, a first motor 75 is installed on the top of the gantry 74, and the first motor 75 can drive the first lead screw 76 to rotate inside the gantry 74. Since the first lead screw 76 is threadedly installed with the second mounting base 77, and the second pressure roller 78 is rotatably installed with the second mounting base 77, the rotation of the first lead screw 76 can realize the vertical adjustment of the second pressure roller 78, thereby realizing the adjustment of the tightness of the flexible label tape.

[0037] See attached document Figure 1 , Figure 3 and Figure 4 In this embodiment, the die-cutting mechanism 6 includes a frame 61 and a first pressure roller 64. A lifting screw 62 is rotatably installed inside the frame 61. The lifting screw 62 drives the first mounting base 63 to move vertically, so that the first pressure roller 64 moves to the top of the die-cutting mold 66. The die-cutting mold 66 is fixedly installed inside the discharge cavity 65.

[0038] In the above embodiment, since the discharge chamber 65 is opened inside the frame 2, and the frame 61 is located on both sides of the top of the discharge chamber 65 and is fixedly installed with the frame 2, and there are two first mounting seats 63, and the first pressure roller 64 is rotatably installed between the first mounting seats 63, when the lifting screw 62 is rotated, since the lifting screw 62 is threadedly installed with the first mounting seat 63, the first mounting seat 63 can drive the first pressure roller 64 to move vertically.

[0039] According to the above structure, since the first pressure roller 64 is located on top of the die-cutting mold 66, it can cooperate with the die-cutting mold 66 to die-cut the label when the first pressure roller 64 moves.

[0040] Furthermore, since the die-cutting mold 66 is installed to the frame 2 by bolts and is located inside the discharge cavity 65, different die-cutting molds 66 can be replaced according to different needs, thereby improving the practicality of the laser marking machine.

[0041] See attached document Figure 1 , Figure 3 and Figure 5 In this embodiment, the support mechanism 3 includes a base 31, a fixed seat 34 and a slider 35. The base 31 is hinged to the top plate 32 through a scissor brace 33, and an adjusting screw 36 is rotatably installed on one side of the fixed seat 34.

[0042] In the above embodiment, since the fixed seat 34 is fixedly installed with the base 31, and the scissor brace 33 is hinged with the slider 35, and the slider 35 is threadedly installed with the adjusting screw 36 and slidably installed with the fixed seat 34, when the adjusting screw 36 is rotated, the slider 35 can be driven to move linearly inside the fixed seat 34, thereby driving one end of the scissor brace 33 to move synchronously. The other end of the scissor brace 33 located on the same side of the base 31 is slidably installed with the top plate 32. Therefore, under the action of the scissor brace 33, the top plate 32 can be driven to move vertically, thereby realizing the height adjustment of the laser marking mechanism 4.

[0043] The working principle of this utility model is as follows: Based on the different widths of the label tape, the second motor 10 is started to drive the second lead screw 11 to rotate, causing the connecting block 9 to drive the winding mechanism 7 and the unwinding mechanism 8 to adjust at the top of the base plate 1. After the label tape is positioned at a suitable bottom position of the laser marking mechanism 4, the adjusting screw 36 is rotated to drive the slider 35 to slide inside the fixed seat 34, causing one side of the scissor brace 33 to move. Since the other side of the scissor brace 33 is hinged to the top plate 32 and the base 31, the top plate 32 can drive the laser marking mechanism 4 to adjust its height to a suitable level before laser marking can begin. Meanwhile, the unwinding mechanism 8 winds the label tape roll... During unwinding, the first motor 75 of both the winding mechanism 7 and the unwinding mechanism 8 is activated simultaneously, causing the first lead screw 76 to rotate. The first lead screw 76 drives the second mounting base 77 and the second pressure roller 78 to move downwards, thereby adjusting the tightness of the label tape to a suitable level before marking. After marking is completed, the first mounting base 63 and the first pressure roller 64 are moved downwards by rotating the lifting screw 62. With the cooperation of the first pressure roller 64 and the die-cutting mold 66, the label is cut off and falls into the discharge cavity 65, thus completing the label marking and die-cutting work. At the same time, the remaining die-cut label tape can be wound up by the winding mechanism 7.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
