DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings.
[0019] like Figure 1 , 2 As shown in Figures 3 and 4, a laser typing device for plastic tubes with clearer typing comprises a laser typing machine 1, wherein the laser typing machine has a laser engraving head 2, wherein the laser engraving head faces a plastic tube running path 3, and is characterized in that an oiling device 4 is installed at the rear side of the laser typing machine, wherein the oiling device is installed with an oiling component 5, and the oiling component faces the plastic tube running path.
[0020] Usage: The plastic tube moves from back to front. When producing the plastic tube, the oiling device is turned on, and the oiling device applies oil to the plastic tube. Then the plastic tube moves forward to the laser engraving head and is engraved by the laser engraving head. Since the oil has been applied before, the oil plays an auxiliary engraving role in the laser engraving process. In this way, the engraved logo 16 is more eye-catching, not easy to be corroded, and still clearly recognizable for a long time.
[0021] Example 1: Figure 1-2 As shown, further, the oiling device includes an oil tank 6, which can contain oil. The oil tank is provided with a spray port 7, and the spray port faces the travel path of the plastic pipe.
[0022] In this way, when in use, oil is filled in the oil tank, the spray port is opened, the spray port sprays oil toward the plastic pipe, and then the plastic pipe is engraved by the laser engraving head, thereby achieving the purpose of the utility model.
[0023] Example 1: Figure 1-2 As shown, further, the oil tank has an oil outlet switch 8, and the oil outlet switch is turned on or off to control the opening or closing of the spray port. The oil outlet switch is connected to a control device 9, and the control device can control the interval time and duration of the opening of the oil outlet switch.
[0024] This arrangement is more fuel-efficient, and the principle is as follows: since the laser engraved mark on the plastic tube is engraved at a certain distance, such as engraving a mark every 1m, the length of the mark is 10cm, so there is no need to apply oil everywhere, only the 10cm is needed. The control device 9 can calculate and adjust the oil outlet interval and oil outlet duration of the oil outlet switch in advance, so that the oil sprayed from the spray port is just at the position where the mark is needed, thereby achieving the purpose of saving fuel.
[0025] The control device is a component in the prior art.
[0026] Example 2: Figure 3-4 As shown, further, the oiling device includes an oil tank 10, on which is mounted a first oiling roller 11, which rotates around a first rotating shaft 12, with the lower portion of the first oiling roller being in the oil tank, and a second oiling roller 13 being disposed on one side of the plastic pipe travel path 3, which rotates around a second rotating shaft 14, the second oiling roller being in contact with the first oiling roller, and the second oiling roller being in contact with the position where the plastic pipe passes at the same time.
[0027] This can also achieve the purpose of oiling, and the direction of arrow F is the direction of rotation.
[0028] Furthermore, a cooling chamber 15 is provided between the oiling device and the laser printer, and the plastic pipe travels through the cooling chamber.
[0029] Cooling the plastic tube after oiling and before laser marking will result in better engraving and a more eye-catching logo.
[0030] For Example 1, Figure 5 As shown, further speaking, there are multiple spray ports 7, which are arranged in parallel, and the diameter of each spray port is less than 2 mm.
[0031] With this arrangement, multiple spray ports spray oil to the plastic pipe, which has the advantage of more uniform oil spraying.
[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the specification of the present invention.
