Description

Technical Field

[0001] This utility model belongs to the field of laser marking machine technology, and in particular relates to a laser marking machine that is easy to adjust the marking position. Background Technology

[0002] Laser marking machines are mainly used to mark the surface of objects using laser technology. These marks are permanent and cannot be erased, making them suitable for the identification and anti-counterfeiting of various products. For example, in the food processing and production process, laser marking machines are often used to mark information such as production date on the surface of food packaging.

[0003] Chinese utility model patent CN214774869U discloses a laser marking machine that facilitates adjustment of the marking position. It protects the casters to prevent damage from gravity during use and allows for easy fixation when the upright is moved horizontally. Furthermore, the lifting mechanism has few parts, facilitating maintenance. However, after controlling the rotation of the marking machine body, the overall orientation of the device needs to be adjusted, making marking position adjustment inconvenient. Additionally, height adjustment is inconvenient, time-consuming, and labor-intensive.

[0004] Therefore, there is an urgent need to improve existing laser marking machines and provide a laser marking machine that is easy to operate, saves time and effort, and allows for easy adjustment of the marking position. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a laser marking machine that is reasonably designed, simple in structure, easy to operate, time-saving, labor-saving, and easy to adjust the marking position, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser marking machine for easy adjustment of marking position includes a counterweight base and a marking assembly. A vertical guide rail is fixedly installed above the middle of the counterweight base. A groove is formed on the upper left side wall of the vertical guide rail. A lead screw is rotatably mounted inside the groove. A first servo motor is fixedly installed on the top outer wall of the vertical guide rail. The output end of the first servo motor is fixedly connected to the top end of the lead screw. The marking assembly is connected to the lead screw through a bracket assembly. The bracket assembly includes a first bracket threaded onto the outside of the lead screw. A first conical tooth is fixedly connected to the bottom of the first bracket away from the vertical guide rail. The first conical tooth is drivenly connected to the marking assembly. A second bracket stacked vertically is bearing-connected to one end of the first bracket. A fixed frame is fixedly installed on the first bracket. A second servo motor is fixedly installed on the top inner side of the fixed frame. The output shaft of the second servo motor is drivenly connected to the marking assembly through the second bracket.

[0008] Preferably, the longitudinal section of the second bracket is an inverted "L" shape.

[0009] Preferably, the other end of the first bracket away from the second bracket is engaged and slidably located inside the groove.

[0010] Preferably, the rotational connection point of the first bracket and the second bracket is on the same vertical line as the output shaft of the second servo motor and the center of the first bevel tooth.

[0011] Preferably, the coding assembly includes an optical path box, a second conical tooth, a rotating shaft, a third conical tooth, and a coding device. The optical path box is fixedly installed at the bottom of the second bracket. The second conical tooth is mounted on the bearing on the right side of the front end of the optical path box. The rotating shaft is connected to the bearing at the front end of the optical path box. The third conical tooth is fixedly sleeved on the outer side of the rotating shaft. The coding device is fixedly connected to the front end of the rotating shaft.

[0012] Preferably, the first and third conical teeth have the same diameter and both are engaged with the second conical tooth, which is a double-sided tooth.

[0013] Preferably, self-locking casters are fixedly installed at the four right angles of the bottom of the counterweight base.

[0014] Preferably, a power supply box is fixedly installed on the upper right side of the counterweight base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, the laser marking machine utilizes a first servo motor to control the lead screw to rotate slowly and uniformly, thereby controlling the support assembly and the marking assembly to move stably up and down along the slide groove synchronously. This enables quick adjustment of the marking machine height. Compared with the prior art, this laser marking machine adjusts the marking machine height more quickly and effortlessly, with better results.

[0017] When it is necessary to print codes on the side of a product, this utility model can activate the second servo motor to control the second bracket to drive the entire printing assembly to rotate 90° synchronously around the first conical tooth. During this process, the second conical tooth that meshes with the first conical tooth can rotate, thereby causing the third conical tooth that meshes with the second conical tooth to drive the rotating shaft and the printer to rotate. Since the diameters of the first and third conical teeth are equal, the rotation range of the rotating shaft and the printer is also 90°. This allows for convenient adjustment of the printing position of the printer without adjusting the orientation of the equipment, making the operation simpler and more practical.

[0028] In a preferred embodiment, based on the above structure, the bracket assembly 8 further includes a first bracket 81, a first conical tooth 82, a second bracket 83, a fixing frame 84, and a second servo motor 85. The first bracket 81 is fixedly connected to the bottom of one end away from the vertical guide rail 3 with the first conical tooth 82. The other end of the first bracket 81 is threaded onto the outside of the lead screw 6. One end of the first bracket 81 is bearing connected to the second bracket 83. The longitudinal section of the second bracket 83 is an inverted "L" shape. The fixing frame 84 is fixedly installed above one end of the first bracket 81 near the second bracket 83. The second servo motor 85 is fixedly installed on the inner top of the fixing frame 84. The output shaft of the second servo motor 85 is connected to the inkjet printing assembly 9 through the second bracket 83.

[0029] Based on the above structure, preferably, the output shaft of the second servo motor 85 is fixedly connected to one end of the second bracket 83, and the other end of the second bracket 83 is fixedly connected to the inkjet printing assembly 9.

[0030] In this embodiment, the second servo motor 85 can control the second bracket 83 to drive the inkjet printing assembly 9 to rotate and adjust, which facilitates quick adjustment of the inkjet printing position.

[0031] As a preferred embodiment, based on the above structure, the other end of the first bracket 81, away from the second bracket 83, is engaged and slidably located inside the slide groove 5.

[0032] In this embodiment, the use of the lead screw 6 and the slide 5 facilitates the stable lifting and lowering adjustment of the bracket assembly 8 and the inkjet printing assembly 9 in the vertical direction.

[0033] As a preferred embodiment, based on the above structure, the rotational connection point of the first bracket 81 and the second bracket 83 is on the same vertical line as the output shaft of the second servo motor 85 and the center of the first bevel tooth 82.

[0034] In this embodiment, it is convenient to control the second bracket 83 to drive the inkjet printing assembly 9 to rotate around the first conical tooth 82 as the center.

[0035] In a preferred embodiment, based on the above structure, the coding assembly 9 further includes a light path box 91, a second conical tooth 92, a rotating shaft 93, a third conical tooth 94, and a coding printer 95. The light path box 91 is fixedly installed at the bottom of the second bracket 83. The second conical tooth 92 is mounted on the bearing on the right side of the front end of the light path box 91. The rotating shaft 93 is connected to the bearing at the front end of the light path box 91. The third conical tooth 94 is fixedly sleeved on the outer side of the rotating shaft 93. The coding printer 95 is fixedly connected to the front end of the rotating shaft 93.

[0036] In a preferred embodiment, based on the above structure, the first conical tooth 82 and the third conical tooth 94 have the same diameter and both are engaged with the second conical tooth 92, which is a double-sided tooth.

[0037] In this embodiment, when the second bracket 83 drives the inkjet component 9 to rotate around the first conical tooth 82, the rotating shaft 93 and the inkjet printer 95 can be controlled to rotate 90° by the second conical tooth 92 and the third conical tooth 94, so that the inkjet position of the inkjet printer 95 can be conveniently adjusted without adjusting the orientation of the equipment, making the operation simpler.

[0038] The working principle of this utility model is as follows:

[0039] When in use, first push the laser marking machine to the designated position, and start the first servo motor 7 according to the height of the food outer packaging. Control the lead screw 6 to rotate slowly and uniformly, so as to control the bracket assembly 8 to drive the marking assembly 9 to synchronously and stably adjust the height of the marking machine 95 along the slide 5. Then, when the item moves to the area directly below the marking machine 95 through the conveyor belt assembly line, the marking of the outer packaging can begin.

[0040] When it is necessary to print on the side of the product, the second servo motor 85 can be started first to control the second bracket 83 to drive the entire printing assembly 9 to rotate synchronously around the first conical tooth 82 by 90°. During this process, the second conical tooth 92, which meshes with the first conical tooth 82, can be controlled to rotate, thereby enabling the third conical tooth 94, which meshes with the second conical tooth 92, to drive the rotating shaft 93 and the printer 95 to rotate. Since the diameters of the first conical tooth 82 and the third conical tooth 94 are equal, the rotation amplitude of the rotating shaft 93 and the printer 95 is equal to the rotation amplitude of the second bracket 83, both being 90°. At this time, the printer 95... Figure 5 The state shown allows for convenient adjustment of the coding position of the inkjet printer 95 without adjusting the orientation of the device, facilitating quick switching between coding positions on the top or side of the outer packaging, making operation simpler and more practical.

[0041] It should be noted that this solution mainly improves the quick adjustment function of the inkjet printer 95's printing position. The specific structure, power supply method and working principle of the inkjet printer 95 all adopt mature existing technologies, so they will not be described in detail.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
