Description

Technical Field

[0001] The utility model relates to the technical field of printing positioning, and more specifically to a printing point positioning device of a packaging bag laser engraving printer. Background Art

[0002] A laser printer is a device that uses laser technology for printing. It processes the printing material through a laser beam to print text, patterns or images. The laser printer has high-precision, high-speed and high-quality printing capabilities and is suitable for printing various materials such as paper, plastic, packaging bags, etc. The printing point positioning device is mainly used to limit and fix the printed material to prevent it from moving during the printing process, which can improve the printing accuracy and stability of the laser printer.

[0003] Chinese patent publication number CN221473890U discloses a positioning base for a laser marking machine. When the first clamping rod or the second clamping rod is disjointed from the transverse groove, the first clamping rod or the second clamping rod directly contacts the product. However, in order to prevent the first clamping rod or the second clamping rod from being affected by the elastic member (spring) and causing the position of the product to change, a positioning pin can be inserted into the positioning hole and restrict the first clamping rod or the second clamping rod when the first clamping rod or the second clamping rod is disjointed from the transverse groove, thereby preventing the first clamping rod or the second clamping rod from affecting the positioning of the product, thereby improving the accuracy of the marking mechanism.

[0004] However, when laser printing is performed on packaging bags, since the packaging bags are relatively soft and lightweight, they are easily displaced when there is external vibration or wind. The displacement will cause the printed pattern to be misplaced or blurred, affecting the printing quality, making the final product unable to achieve the expected visual effect, thereby reducing the yield rate.

[0005] Therefore, it is necessary to provide a printing point positioning device for a packaging bag laser engraving printer to solve the above problems. Utility Model Content

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] Based on this, the problem in the related technology that the packaging bags are relatively soft and light in weight can be improved. Therefore, when external vibrations or wind blows, the packaging bags are easily displaced. The displacement will cause the printed pattern to be misplaced or blurred, affecting the printing quality, making the final product unable to achieve the expected visual effect, thereby reducing the yield rate.

[0035] See also Figure 1-Figure 7 A printing point positioning device of a packaging bag laser engraving printer includes a laser printer cabinet 1, a moving device 2 and a laser head 3. The moving device 2 is fixedly installed on the top of the laser printer cabinet 1, and the laser head 3 is installed on the outer end of the moving device 2. A workbench assembly 7 is provided on the top of the laser printer cabinet 1, and a plurality of abutment assemblies 6 are provided on the outer end of the workbench assembly 7. A driving assembly 4 is provided on the top of the laser printer cabinet 1, and a positioning assembly 5 is provided on the top of the workbench assembly 7. The positioning assembly 5 includes a fixed sleeve 54 and a rotating block 56. The fixed sleeve 54 is sleeved on the outside of the rotating block 56. A driving slide groove 58 is opened at the outer end of the fixed sleeve 54, and the driving slide groove 58 is arranged in an arc shape.

[0036] The device in this scheme is mainly used to limit and fix the packaging bag so that it will not be moved by external interference during laser printing. A moving device 2 is installed on the top of the laser printer cabinet 1, and a laser head 3 is installed on the outer end of the moving device 2. The moving device 2 is mainly used to drive the laser head 3 and enable the laser head 3 to move and change its height. The laser head 3 is mainly used to emit a laser beam. The laser beam emitted by the laser is controlled by the control system inside the laser printer cabinet 1. The laser beam is irradiated onto the printing material. The high energy of the laser can change the color and structure of the material surface, and the material is locally heated and evaporated, thereby producing the desired pattern or text on the material surface. The workbench assembly 7 is installed on the top of the laser printer cabinet 1. Four abutment assemblies 6 and positioning assembly 5 are provided on the workbench assembly 7, and the driving Component 4 is installed on the laser printer cabinet 1 and is also located at the top of the positioning component 5. By installing the workbench body 71 directly below the laser head 3, and then aligning the four corners of the packaging bag with the inner sides of the four abutment blocks 61, the cylinder device 43 drives the drive rod 42 to move downward. At this time, since the limit pin 57 is restricted by the drive slide 58, the rotating block 56 drives the positioning pressure plate 55 to rotate while moving downward, so that the positioning pressure plate 55 can squeeze and fix the corners of the package, and no displacement will occur during printing, thereby improving the printing quality. It is worth mentioning that the device needs to be customized to match the size of the packaging bag. However, when the size of the packaging bag does not match the positioning component 5, only one or two corners of the packaging bag can be fixed. Since the laser printing will not contact the packaging bag, fixing one corner can also prevent it from displacement.

[0037] Optionally, in some embodiments, see Figure 6 The workbench assembly 7 includes a workbench body 71, and a plurality of fixing brackets 72 are fixedly connected to the outside of the workbench body 71. The fixing brackets 72 are installed on the top of the laser printer cabinet 1 by bolts. Four through holes 73 are opened at the outer end of the workbench body 71. The workbench body 71 is located below the laser head 3.

[0038] The workbench body 71 in this solution is fixed with fixing frames 2 72 on all four sides. The fixing frames 2 72 are fixed to the top of the laser printer cabinet 1 by bolts. At this time, the workbench body 71 is located below the laser head 3. Through holes 73 are opened at the four corners of the workbench body 71. The through holes 73 are L-shaped. The inner side of each through hole 73 is installed with abutment components 6. When printing, the packaging bag can be placed on the top of the workbench body 71.

[0039] Optionally, in some embodiments, see Figure 3-Figure 5The positioning assembly 5 also includes two connecting rods 51, and four connecting rings 53 are fixed on the inner side of the two connecting rods 51. The connecting rings 53 are fixedly installed on the outer side of the fixed sleeve 54. The outer ends of the connecting rods 51 are fixedly connected to multiple fixing frames 52, and the bottom ends of the multiple fixing frames 52 are all fixedly installed on the top of the workbench body 71.

[0040] The outer end of the rotating block 56 is fixedly connected to a limit pin 57, and the limit pin 57 is slidably connected to the driving slide 58. The bottom end of the rotating block 56 is fixedly connected to a positioning pressure plate 55, which is arranged in a semicircular shape, and an anti-slip rubber strip is provided at the bottom end of the positioning pressure plate 55.

[0041] The driving assembly 4 includes a driving frame 41 and two cylinder devices 43 . Four driving rods 42 are fixedly connected to the bottom end of the driving frame 41 . The bottom ends of the driving rods 42 are rotatably connected to the top end of the rotating block 56 .

[0042] The two cylinder devices 43 are both fixedly mounted on the top of the laser printer cabinet 1 . The cylinder devices 43 are externally connected to an air supply device, and the output ends of the cylinder devices 43 are fixedly connected to the driving frame 41 .

[0043] The driving assembly 4 in this solution is mainly used to drive the positioning assembly 5. The two cylinder devices 43 are fixed to the top of the laser printer cabinet 1. The cylinder devices 43 require an external air supply component to increase power. The external air supply device is mainly composed of a gas compressor and a pressure regulator. By supplying air to the inside of the cylinder device 43, the air pressure causes the output end of the cylinder device 43 to move telescopically. The driving frame 41 is fixed at the output end of the cylinder device 43. The four corners of the driving frame 41 are fixed with driving rods 42. The driving rods 42 are mainly used to transmit the downward force provided by the cylinder device 43.

[0044] The four fixed sleeves 54 are respectively located directly below the four driving rods 42. The outer end of each fixed sleeve 54 is fixed with two connecting rings 53. Four are divided into a group. The four connecting rings 53 are connected to each other through the connecting rod 51. The outer ends of the two connecting rods 51 are fixed with multiple fixing frames 52. The bottom end of the fixing frame 52 is fixed to the top of the workbench body 71, so that the positioning assembly 5 can be installed above the workbench body 71. The inside of the fixed sleeve 54 is provided with a rotating block 56. The top of the rotating block 56 is rotatably connected to the driving rod 42. The outer end of the fixed sleeve 54 is fixed with a rotating block 56. A driving slot 58 is provided at the end thereof. The driving slot 58 is arc-shaped and is wound around the outer end of the fixed sleeve 54 from top to bottom. The starting and ending points of the driving slot 58 are not in the same height, but are laterally on the same axis and are arranged at 180°. A limiting pin 57 is fixed at the outer end of the rotating block 56. The limiting pin 57 is slidably connected to the driving slot 58. A positioning pressure plate 55 is fixed at the bottom end of the rotating block 56. An anti-slip rubber strip made of rubber is provided at the bottom end of the positioning pressure plate 55. When the positioning pressure plate 55 is pressed on the packaging bag, its friction can be increased.

[0045] When the cylinder device 43 drives the driving frame 41 to move downward, the driving rod 42 will drive the rotating block 56 downward. Since the limit pin 57 is restricted by the driving slide 58, when the driving rod 42 is pressed downward, the rotating block 56 will also be restricted and guided by the driving slide 58 while moving downward, causing it to rotate itself. At this time, the positioning pressure plate 55 fixed at the bottom end of the rotating block 56 will also rotate, so that the positioning pressure plate 55 can be moved to the top of the corner of the packaging bag. When the positioning pressure plate 55 compresses the abutment block 61 downward and contacts the workbench body 71, When the corner of the packaging bag is abutted, the limit pin 57 will move to the end of the driving slide 58, and the positioning pressure plate 55 will also rotate to 180°, just pressing the corner of the packaging bag. If the positioning pressure plate 55 cannot be rotated, it will block the line of sight. Through the characteristic that the positioning pressure plate 55 can rotate and the positioning pressure plate 55 is set in a semicircular shape, when the packaging bag is placed on the workbench body 71 and aligned with the inner corner of the abutment block 61, the positioning pressure plate 55 will not block the implementation and hinder the operation, thereby facilitating the alignment of the packaging bag on the workbench body 71.

[0046] Optionally, in some embodiments, see Figure 7 The abutment assembly 6 includes a shell 63 and an abutment block 61. The abutment block 61 is L-shaped. The shell 63 is fixedly installed at the bottom end of the workbench body 71. A plurality of telescopic springs 62 are arranged inside the shell 63. The two ends of the telescopic spring 62 are respectively fixedly connected to the abutment block 61 and the bottom end of the shell 63. The abutment block 61 is slidably connected to the inner wall of the shell 63, and the abutment block 61 passes through the through hole 73 and extends above the workbench body 71.

[0047] The abutment assembly 6 in this solution is mainly used to position the packaging bag so that it can be placed in the same position every time it is placed on the workbench body 71. The shell 63 is fixed to the bottom end of the workbench body 71, just below the through hole 73. A plurality of telescopic springs 62 are installed inside the shell 63. The abutment block 61 is slidably installed inside the shell 63. The force of the telescopic spring 62 can push the abutment block 61 upward to pass through the through hole 73 and bulge upward. The abutment block 61 is set in an L shape, and its inner corner is 90 degrees. It is set so that it can be aligned with the corner of the packaging bag. When the positioning pressure plate 55 is pressed down, the abutment block 61 will be retracted into the shell 63, and the surface of the abutment block 61 will be flush with the workbench body 71. The positioning pressure plate 55 can press the corner of the packaging bag onto the workbench body 71, so as to facilitate user positioning and make the placement position the same each time, which is convenient for the laser printer to perform origin positioning. When the positioning pressure plate 55 is pressed down, the abutment block 61 will be compressed into the shell 63, so that the abutment block 61 will not affect the positioning pressure plate 55 to fix the packaging bag.

[0048] Working principle: When using the device to laser print a packaging bag, the packaging bag must first be placed on the workbench body 71, and the four corners of the packaging bag must be aligned with the inner sides of the four abutment blocks 61. Then, when the cylinder device 43 drives the driving frame 41 to move downward, the driving rod 42 will drive the rotating block 56 downward. While the rotating block 56 moves downward, the limiting latch 57 is slidably connected to the driving slide 58, so it will be restricted and guided by the driving slide 58, causing the rotating block 56 to rotate itself. At this time, the positioning pressure plate 55 fixed at the bottom end of the rotating block 56 will also rotate, so that the positioning pressure plate 55 can be moved to the top of the corner of the packaging bag. When the positioning pressure plate 55 compresses the abutment block 61 downward and abuts against the workbench body 71, the corner of the packaging bag is pressed, so that the positioning pressure plate 55 can squeeze and fix the corner of the packaging, and no displacement will occur during printing, thereby improving the printing quality.

[0049] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
