Description

Technical Field

[0001] The utility model relates to the technical field of numerical control laser cutting machines, in particular to a numerical control laser cutting machine with a protective function. Background Art

[0002] The CNC cutting machine has the characteristics of fast cutting speed and small cutting gap during the cutting process. It can perform high-speed precision cutting and punching of various metals and materials. With the help of the follow-up dynamic focusing device, the cutting quality can always be maintained consistent during the cutting process. However, the existing laser cutting machine lacks good protection, which makes the device itself easy to be damaged, causing many inconveniences when people use it.

[0003] For example, Chinese patent announcement No. CN211305236U discloses a laser cutting machine with a protective function. When the cutting machine is not in use, the sheath can be put on the outside of the cutting head of the cutting machine to protect the cutting head of the cutting machine. The connecting rod is pushed and the rubber card ball is inserted into the card slot. The sheath can be fixed to prevent it from falling. The side wall of the plastic elastomer is a folding structure that can be extended. The upper and lower sides are relatively hard, similar to the structure of a spring bottle. The inner cavity is sealed. When the device is bumped, it is compressed, and the internal gas is squeezed. The air pressure is outward, so the block will be pressed into the retaining ring to slow down the outflow of gas, acting as an air cushion to reduce shock for the cutting machine and prevent it from being damaged. When the device is not bumped, the plastic elastomer is lifted up under the support of the second spring, and the internal air pressure is reduced. At this time, the air pressure is inward, and the block is pushed away from the retaining ring by the external airflow, so that air enters the plastic elastomer until the air pressure is stable. The block is reinserted into the retaining ring under the push of the first spring. At the same time, the second spring can support the plastic elastomer to assist it in further shock reduction, which brings convenience to people's use.

[0004] However, the laser cutting machine with protective function in the above application can only protect the cutting head when it is shut down, but cannot provide protection when the cutting head is in use. In addition, when laser cutting some materials, toxic fumes may be generated, which need to be purified. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a CNC laser cutting machine with protection function. Utility Model Content

[0006] The purpose of the utility model is to provide a CNC laser cutting machine with a protective function to solve the problem that the laser cutting machine with a protective function proposed in the above-mentioned background technology can only protect the cutting head when it is shut down, but cannot provide a protective effect when the cutting head is in use, and when laser cutting some materials, toxic fumes may be generated, which need to be purified.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a CNC laser cutting machine with a protective function, comprising a cutting table and a laser cutter, the laser cutter being installed on the cutting table, a protective device being provided at the bottom of the laser cutter, and a cutting device being provided on the upper surface of the cutting table.

[0008] The protection device comprises a protection unit and a purification unit.

[0009] The protection unit includes a protective cover, a fitting seat, and a nozzle hole. The protective cover is installed at the bottom of the laser cutter, the fitting seat is fixedly connected to the inside of the protective cover, and the nozzle hole is opened at the bottom center of the fitting seat. The cutting head of the laser cutter is protected by the protective cover, and the laser emitted by the cutting head is emitted through the nozzle hole on the fitting seat, which does not affect the cutting process. Fitting seats with different apertures can be selected according to different processing materials, and the fitting seat can reduce the impact of the laser on the protective cover.

[0010] A further improvement is that the protective cover is made of polycarbonate, the protective cover is translucent brown-red, the lower half of the protective cover is a foldable soft cover, the brown-red protective cover can effectively absorb blue light to protect the eyes, and the translucent protective cover can better observe the status of laser cutting.

[0011] A further improvement is that the purification unit includes a purification pipe, an activated carbon plate, and a micro fan. The purification pipe is fixedly connected to the middle of the right outer surface of the protective cover, the activated carbon plate is installed on the left side of the interior of the purification pipe, and the micro fan is installed on the right side of the interior of the purification pipe. The micro fan rotates to suck air, and the smoke generated during the cutting process is sucked into the interior of the protective cover and flows through the activated carbon plate inside the purification pipe. The toxic smoke is purified by the activated carbon plate to better protect the health of the operator.

[0012] A further improvement is that ventilation holes are evenly opened on the outer surface of the activated carbon plate, and a dustproof net is installed at the right end of the purification pipe. The dustproof net is set to prevent dust from entering the interior of the protective cover through the purification pipe, thereby affecting the laser cutting process.

[0013] A further improvement is that the cutting device comprises a moving unit and a transverse moving unit.

[0014] The moving unit includes an electric guide rail, a guide rail seat, and a limit block. The two electric guide rails are respectively installed on the left and right sides of the upper surface of the cutting table. The two guide rail seats are respectively slidably connected to the electric guide rails. The two groups of limit blocks are respectively fixedly connected to the front and rear ends of the electric guide rails. The setting of the limit blocks prevents the guide rail seat from detaching from the electric guide rail.

[0015] A further improvement is that the transverse movement unit includes a cutting frame, an electric slide rail, and a slide rail seat. The cutting frame is fixedly connected to the top of the two guide rail seats, the electric slide rail is installed on the lower surface of the cutting frame, the slide rail seat is slidably connected to the electric slide rail, and a laser cutter is installed at the bottom of the slide rail seat. The guide rail seat is driven to move forward and backward on the electric guide rail, thereby driving the cutting frame on it to move forward and backward, and at the same time driving the slide rail seat to move horizontally left and right on the electric slide rail, thereby driving the laser cutter at the bottom of the slide rail seat to move forward and backward, left and right, thereby cutting out the desired shape.

[0016] A further improvement is that mounting grooves are equidistantly provided on the upper surface of the cutting table, and rollers are rotatably connected inside the mounting grooves. The blank is placed on the cutting table, and when loading the blank, friction pushes the rollers to rotate inside the mounting grooves, which makes loading easier and saves workers' physical strength.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The CNC laser cutting machine with protective function protects the cutting head of the laser cutter through a protective cover, and the laser emitted by the cutting head is emitted through the nozzle hole on the fitting seat, which does not affect the cutting process. Fitting seats with different apertures can be selected according to different processing materials, and the fitting seat can reduce the impact of the laser on the protective cover.

[0019] 2. This CNC laser cutting machine with protective function uses a micro fan to rotate and suck air, sucking the smoke generated during the cutting process into the inside of the protective cover and flowing through the activated carbon plate inside the purification tube. The activated carbon plate is used to purify the toxic smoke to better protect the health of the operator. BRIEF DESCRIPTION OF THE DRAWINGS
