Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and more specifically, to a novel laser engraving machine with a cooling function. Background Technology

[0002] Laser engraving machines are advanced devices that use lasers to engrave materials. Unlike mechanical engraving machines and other traditional manual engraving methods, which use mechanical means.

[0003] Currently, during the operation of a laser engraving machine, it is necessary to dissipate heat from the laser engraving head. However, the most common heat dissipation method is to use a cooling fan for air cooling, which not only has poor heat dissipation effect, but also requires the cooling fan to be running continuously, which is a waste of electricity.

[0004] For example, CN218253401U discloses a rapid cooling structure for a laser engraving machine, which includes a base, with supports on both sides of the upper surface of the base, a crossbeam installed on the upper end of the inner side of the two supports, a moving mechanism on the outer side of the crossbeam, and a laser engraving head fixed on one outer side of the moving mechanism.

[0005] As can be seen from the above-mentioned publicly available solutions, the laser engraving head dissipates heat through an exhaust fan. However, the cooling mechanism only cools the air entering the baffle and cannot directly act on the surface of the laser engraving head, which greatly reduces the cooling effect. Moreover, the exhaust fan needs to be continuously turned on, which not only consumes more power but also shortens its service life. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a novel laser engraving machine with a cooling function. This novel laser engraving machine with a cooling function, through the setting of a connecting seat, flow channel, heat insulation cover, guide groove and heat dissipation fan, allows cooling water to circulate and contact the surface of the laser engraving head for heat dissipation. At the same time, it achieves dual heat dissipation through water cooling and air cooling, which greatly improves the cooling effect. Furthermore, through the setting of a temperature control switch, the operation of the heat dissipation fan can be controlled according to the actual temperature of the laser engraving head, so that the heat dissipation fan does not need to be in a continuous state, which has an energy-saving function.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A novel laser engraving machine with a cooling function includes a laser engraving head. A baffle is detachably connected to one side of the laser engraving head, and a heat insulation cover is detachably connected to the side of the baffle. A connecting seat and heat sink are provided on the surface of the laser engraving head. An inlet pipe and an outlet pipe are fixedly installed on the side of the connecting seat, with one end of each pipe connected to a flow channel. A first flexible hose, a second flexible hose, and a temperature control switch are fixedly installed on the inner wall of the heat insulation cover. One end of each hose is connected to a guide groove. An installation hole is provided on the end face of the heat insulation cover. A cooling fan is detachably connected to the inner wall of the mounting hole. The suction end of the cooling fan is equipped with a limiting ring. This new type of laser engraving machine with cooling function allows cooling water to circulate through the connecting seat, flow channel, heat insulation cover, guide groove and cooling fan, so that it contacts the surface of the laser engraving head for heat dissipation. At the same time, dual heat dissipation is achieved through water cooling and air cooling, which greatly improves the cooling effect. Furthermore, through the set temperature control switch, the operation of the cooling fan can be controlled according to the actual temperature of the laser engraving head, so that the cooling fan does not need to be in a continuous state, which has an energy-saving function.

[0009] Furthermore, the connector has an outlet and an inlet at each end, one end of which is connected to the flow channel, and the other end of which is fixedly connected to one end of the first hose and the second hose, respectively, to facilitate the circulation of cooling water within the connector and the insulation cover.

[0010] Furthermore, both the connecting seat and the heat insulation cover are provided with mounting plates on one side, and fastening screws are fitted onto the surface of the mounting plates, while screw holes are provided on the surface of the baffle.

[0011] Furthermore, the heat sink, insulation cover, and connecting base are all made of thermally conductive metal, and the surface of the heat sink is in contact with the inner wall of the insulation cover, which facilitates the cooling of the heat sink by the cold air from the insulation cover.

[0012] Furthermore, the temperature control switch is equipped with a temperature detection sensor, and the temperature control switch is electrically connected to the cooling fan via a wire, so that the cooling fan can be automatically turned on and off based on the temperature.

[0013] Furthermore, both the inlet and outlet pipes are equipped with pipe joints at one end to facilitate the connection of cooling water pipes.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This solution, through the design of the connecting seat, flow channel, heat insulation cover, guide groove and heat dissipation fan, allows the cooling water to circulate and contact the surface of the laser engraving head for heat dissipation. At the same time, it achieves dual heat dissipation through water cooling and air cooling, which greatly improves the cooling effect.

[0016] This solution uses a temperature control switch to regulate the operation of the cooling fan based on the actual temperature of the laser engraving head, eliminating the need for the cooling fan to be constantly on and thus saving energy. Attached Figure Description

Example

[0023] Please see Figure 1-3A novel laser engraving machine with cooling function includes a laser engraving head 1. The laser engraving head 1 is existing technology, and its composition and working principle are well known to those skilled in the art, and will not be described in detail here. The laser engraving head 1 generates high temperatures during operation. A baffle 2 is detachably connected to one side of the laser engraving head 1, and a heat insulation cover 3 is detachably connected to the side of the baffle 2. The heat insulation cover 3 separates external hot air from internal cold air, improving the cooling effect on the laser engraving head 1. A connecting seat 1 is provided on the surface of the laser engraving head 1. 1 and heat sink 17, water inlet pipe 13 and water outlet pipe 14 are fixedly installed on the side of the connecting base 11.

One end of first hose 35 and second hose 36 is connected to guide groove 34. The end face of heat insulation cover 3 is provided with mounting hole 31. The inner wall of mounting hole 31 is detachably connected with heat dissipation fan 4. Heat dissipation fan 4 is the prior art and is used to extract hot air from inside heat insulation cover 3. The suction end of heat dissipation fan 4 is provided with limit ring 42.

[0024] The connector 11 has an outlet 15 and an inlet 16 at both ends. One end of the outlet 15 and the inlet 16 are connected to the flow channel 12. The other end of the outlet 15 and the inlet 16 are fixedly connected to one end of the first hose 35 and the second hose 36, respectively, so that the cooling water can circulate in the connector 11 and the insulation cover 3. The heat sink 17, the insulation cover 3 and the connector 11 are all made of thermally conductive metal. The surface of the heat sink 17 is in contact with the inner wall of the insulation cover 3, so that the cold air of the insulation cover 3 can cool the heat sink 17.

[0025] In this embodiment, the cooling water can circulate through the connecting seat 11, flow channel 12, heat insulation cover 3, flow guide groove 34 and heat dissipation fan 4, thereby contacting the surface of the laser engraving head 1 for heat dissipation. At the same time, the cooling effect is greatly improved by the dual heat dissipation of water cooling and air cooling. Example

[0026] Please see Figure 1-3A novel laser engraving machine with cooling function includes a laser engraving head 1. The laser engraving head 1 is existing technology, and its composition and working principle are well known to those skilled in the art, and will not be described in detail here. The laser engraving head 1 generates high temperatures during operation. A baffle 2 is detachably connected to one side of the laser engraving head 1, and a heat insulation cover 3 is detachably connected to the side of the baffle 2. The heat insulation cover 3 separates external hot air from internal cold air, improving the cooling effect on the laser engraving head 1. A connecting seat 1 is provided on the surface of the laser engraving head 1. 1 and heat sink 17, water inlet pipe 13 and water outlet pipe 14 are fixedly installed on the side of the connecting base 11. One end of water inlet pipe 13 and water outlet pipe 14 is connected to flow channel 12. The inner wall of heat insulation cover 3 is fixedly installed with first hose 35, second hose 36 and temperature control switch 41. One end of first hose 35 and second hose 36 is connected to guide groove 34. The end face of heat insulation cover 3 is provided with mounting hole 31. The inner wall of mounting hole 31 is detachably connected with heat dissipation fan 4. Heat dissipation fan 4 is the prior art and is used to extract hot air from inside heat insulation cover 3. The suction end of heat dissipation fan 4 is provided with limit ring 42.

[0027] The temperature control switch 41 is equipped with a temperature detection sensor. The temperature control switch 41 is electrically connected to the cooling fan 4 through a wire. The cooling fan 4 can be automatically turned on and off by temperature. One end of the water inlet pipe 13 and the water outlet pipe 14 is equipped with a water pipe connector to facilitate the connection of the cooling water pipe. The connecting seat 11 and the heat insulation cover 3 are both equipped with a mounting plate 32 on one side. The surface of the mounting plate 32 is fitted with fastening screws 33. The surface of the baffle 2 is equipped with screw holes.

[0028] In this embodiment, the temperature control switch 41 can control the operation of the cooling fan 4 according to the actual temperature of the laser engraving head 1, so that the cooling fan 4 does not need to be on all the time, thus saving energy.

[0029] When this new type of laser engraving machine with cooling function is in use, cooling water enters the flow channel 12 through the inlet pipe 13, and then a portion of it flows into the guide groove 34 through the outlet 15 and the first hose 35, thereby cooling the connecting seat 11 and the heat insulation cover 3, and further cooling the heat sink 17 and the laser engraving head 1. The cooling water flowing in the guide groove 34 enters the flow channel 12 through the second hose 36 and the inlet 16, then flows out through the outlet pipe 14, and then flows back into the cooling device for cooling, forming a water cooling cycle. At the same time, when the temperature control switch 41 detects that the internal temperature of the heat insulation cover 3 is too high... When the temperature is high, the cooling fan 4 automatically turns on to dissipate internal heat. Once the temperature drops, the cooling fan 4 automatically turns off. Through the connection seat 11, flow channel 12, heat insulation cover 3, guide groove 34, and cooling fan 4, the cooling water can circulate and contact the surface of the laser engraving head 1 for heat dissipation. At the same time, dual heat dissipation through water cooling and air cooling greatly improves the cooling effect. Furthermore, through the temperature control switch 41, the operation of the cooling fan 4 can be controlled according to the actual temperature of the laser engraving head 1, so that the cooling fan 4 does not need to be on all the time, thus having an energy-saving function.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
