Description

Technical Field

[0001] This utility model relates to the field of tea planting technology, and in particular to a laser marking machine that makes the markings flat and can absorb exhaust gas. Background Technology

[0002] Laser marking machines spray an indelible, permanent mark. It is created by the instantaneous vaporization of a laser directly onto the surface of an object. It can be seen with the naked eye without any auxiliary tools, making it easy for consumers to identify. Existing laser marking machines generally consist of a controller, a laser printhead, and a conveyor belt. First, the mark to be printed is input into the controller. Then, the controller transmits the instruction to the laser printhead, which has a sensor. When the material on the conveyor belt is transported to the laser printhead, the sensor controls the laser printhead to print the mark on the material surface.

[0003] In continuous inkjet printing operations, it is necessary to use a conveyor and a laser marking machine in conjunction; however, existing conveyors usually only have basic conveying functions and cannot ensure that the same batch of workpieces are marked in the same location, which directly affects the marking accuracy and uniformity, and this needs to be improved. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the conveyor cannot ensure the consistency and accuracy of the coding in the existing technology, and to propose a laser coding machine that makes the coding flat and can absorb exhaust gas.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a laser marking machine that makes the markings flat and can absorb exhaust gas, comprising a conveyor belt, a mounting frame, a laser nozzle, and a leveling device. The mounting frame is fixedly connected to the conveyor belt, the laser nozzle is mounted on the mounting frame, and the leveling device is disposed on the conveyor belt. The leveling device includes a first mounting block and a second mounting block. The first mounting block is mounted on the front side of the conveyor belt, and the second mounting block is mounted on the back side of the conveyor belt. The first and second mounting blocks are symmetrically arranged. A sliding groove is formed on the side of the first and second mounting blocks near the conveyor belt. A lifting plate is slidably connected to the inner wall of the sliding groove. A pressure plate is slidably connected to the surface of the lifting plate. There are two sets of pressure plates. A through hole is formed on the upper surface of the lifting plate. A connecting hole adapted to the through hole is formed on the upper surface of the pressure plate. A bolt is slidably connected to the inner wall of the through hole. The bolt is threadedly connected to the inner wall of the connecting hole. There are multiple sets of through holes, and the multiple sets of through holes are arranged linearly and uniformly.

[0006] Furthermore, there are two sets of mounting blocks, namely mounting block one and mounting block two. The inner wall of mounting block one is rotatably connected to a rotating shaft one, and the inner wall of mounting block two is rotatably connected to a rotating shaft two.

[0007] Furthermore, the surfaces of the first and second rotating shafts located inside the slide groove are provided with threaded grooves, and both the first and second rotating shafts are threadedly connected to the lifting plate.

[0008] Furthermore, a knob is fixedly connected to the top of the first rotating shaft, a double-groove rotating wheel is fixedly connected to the bottom of the first rotating shaft, and a driven wheel is fixedly connected to the bottom of the second rotating shaft.

[0009] Furthermore, there are two sets of the double-groove wheel and the driven wheel. A belt is fitted inside the double-groove wheel and the driven wheel, and a belt is fitted between the two sets of double-groove wheels.

[0010] Furthermore, the laser nozzle is provided with a fixing device, which includes a gas collecting hood. The gas collecting hood is disposed on the surface of the laser nozzle. There are two sets of gas collecting hoods, which are arranged symmetrically. A connecting plate is fixedly connected to the upper surface of each set of gas collecting hoods, and a sliding rod is slidably connected to the inner wall of the connecting plate.

[0011] Furthermore, a spring is sleeved on the surface of the sliding rod, and a limit ring is fixedly connected to one end of the spring. The limit ring is fixedly connected to the surface of the sliding rod, and a U-shaped block is slidably connected to the surface of the sliding rod. The U-shaped block is disposed between two sets of connecting plates, and a connecting pipe is fixedly connected to the inner wall of the gas collection hood.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a leveling device, it is convenient for the conveyor belt to fix different workpieces. In specific use, rotating the knob drives the first rotating shaft to rotate, the first rotating shaft drives the double-grooved wheel to rotate, the double-grooved wheel drives the driven wheel to rotate through the first belt, the driven wheel drives the second rotating shaft to rotate, and at the same time the double-grooved wheel drives another double-grooved wheel to rotate through the second belt. The rotation of the double grooves drives the other set of rotating shafts one and two to rotate. While rotating shafts one and two are rotating, the threaded grooves on their surfaces push the lifting plate. The lifting plate carries the pressure plate up or down. Then the bolts are loosened and the pressure plate is slid. After the pressure plate slides to a suitable position, the bolts are used to fix the pressure plate and the lifting plate together. Thus, the leveling device can directionally transport workpieces of different sizes and thicknesses to the laser nozzle. By setting a leveling device, it is convenient for the conveyor belt to fix different workpieces, improves the adaptability of the laser marking machine, reduces costs and improves production efficiency, thus effectively improving the practicality of the equipment.

[0014] 2. In this utility model, by setting a fixing device, it is easy to install the gas collection hood at the laser nozzle. In actual use, the two sliding rods are pulled respectively. The sliding rods squeeze the spring through the limit ring, and the two connecting plates and the gas collection hood are released from restraint and detach from the surface of the laser nozzle. During operation, the air extraction device connected to the connecting pipe is started. The air extraction device extracts the exhaust gas generated by the printing through the connecting pipe and the gas collection hood. By setting a fixing device, it is easy to quickly install and remove the gas collection hood, and to facilitate the inspection and maintenance of the laser nozzle, thus effectively improving the convenience of the equipment.

[0028] The effect achieved by the above components is that threaded grooves are opened on the first rotating shaft 49 and the second rotating shaft 410, so that the two can push the lifting plate 44 to rise and fall.

[0029] Specifically, a knob 411 is fixedly connected to the top of the first rotating shaft 49, a double-groove rotating wheel 412 is fixedly connected to the bottom of the first rotating shaft 49, and a driven wheel 413 is fixedly connected to the bottom of the second rotating shaft 410.

Then the bolt 48 is loosened and the pressure plate 45 is slid. After the pressure plate 45 slides to the appropriate position, the bolt 48 is used again to fix the pressure plate 45 and the lifting plate 44 together. This allows the leveling device 4 to orient and transport workpieces of different sizes and thicknesses to the laser nozzle 3. By setting up the leveling device 4, it is easy for the conveyor belt 1 to fix different workpieces, improve the adaptability of the laser marking machine, reduce costs and improve production efficiency, thus effectively improving the practicality of the equipment.
