Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a dust cover and a laser cutting machine. Background Technology

[0002] Dust covers on laser cutting machines are used to prevent metal chips and dust generated during the cutting process from entering key components such as the guide rails, lead screws, and transmission systems of the laser cutting machine, thereby reducing wear and malfunctions and extending the service life of the equipment.

[0003] Traditional dust covers installed on the guide rails of laser cutting machines are made of high-temperature resistant three-proof cloth and a frame plate, also known as accordion covers. During the operation of the laser cutting machine, they cover the surface of the guide rails and fold and retract according to the sliding parts of the laser cutting machine. However, in actual use, it has been found that when the dust cover slides and extends with the parts, the volume of the cavity formed by the dust cover and the guide rail increases accordingly. This causes a negative pressure to form in the cavity, which allows external dust and dirt to be sucked into the cavity along the small gaps around the dust cover, corroding and damaging the guide rails and affecting the effectiveness of the dust cover. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when the dust cover slides and extends with the follower component, the volume of the cavity formed by the dust cover and the slide rail increases accordingly, causing a negative pressure to be formed in the cavity. This causes external dust and other particles to be sucked into the cavity along the small gaps around the dust cover, which corrodes and damages the guide rail and affects the performance of the dust cover.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dust cover, including a dust cover body, the dust cover body being mounted on guide rails on both sides of the surface of the cutting machine body, wherein the dust cover body is composed of a dustproof cloth and several skeleton plates connected together, and a ventilation device is provided on the surface of the dust cover body, wherein the ventilation device assists the stable use of the dust cover body with the help of a vent pipe.

[0006] The effect achieved by the above components is as follows: when the dust cover body is installed on the slide rails on both sides of the cutting machine body, and the dust cover body extends during processing, the ventilation devices installed on the surface of the cutting machine body on both sides of the dust cover body ensure the normal flow of air in the cavity of the dust cover body, and it is not easy to form negative pressure that would cause impurities and dust to enter.

[0007] Preferably, the ventilation device includes a mounting frame, wherein the two sides of the mounting frame are respectively connected to the dust cover body and the surface of the cutting machine body, and a vent pipe is provided on the surface of the mounting frame, wherein a vent cover is fixedly connected to the other end of the vent pipe, and a filter screen is fixedly connected to the surface of the vent cover.

[0008] The effect achieved by the above components is as follows: when the dust cover body is installed on the slide rails on both sides of the cutting machine body, the dust cover body extends during the processing, and the ventilation covers on both sides are connected to ensure the flow of gas. This allows the gas to enter the ventilation pipe through the ventilation cover and finally enter the cavity of the dust cover body through the mounting frame. In addition, the filter screen on the surface of the ventilation cover will intercept external impurities and dust, ensuring that the slide rail is not easily corroded or damaged by impurities.

[0009] Preferably, the surface of the ventilation hood is equipped with auxiliary components, wherein the auxiliary components enhance the ventilation effect of the ventilation device.

[0010] The effect achieved by the above components is to ensure that the filter on the ventilator is used stably and that the airflow in the cavity of the dust cover is stable through the setting of auxiliary components.

[0011] Preferably, gears are rotatably arranged on both sides of the surface of the ventilation hood, and a servo motor is arranged on one side of the ventilation hood. The output end of the servo motor is connected to the gears via a coupling. Two limit rods are installed on the surface of the cutting machine body, wherein a toothed plate is slidably arranged on the surface of the limit rod, the toothed plate meshes with the gear, and a brush plate is installed on the surface of the toothed plate.

[0012] The effect achieved by the above components is that the brush plate and exhaust remove dust and impurities from the surface of the filter screen, thereby ensuring the normal operation of the ventilation device.

[0013] Preferably, the auxiliary components also include stabilizer bars installed in the two toothed plate workshops, wherein the stabilizer bars enhance the stability of the toothed plate operation.

[0014] The effect achieved by the above components is that, by setting the stabilizer bar, the toothed plates on both sides of the brush plate can form a certain connection, thereby better ensuring stable and synchronous movement, and thus ensuring the stable use of the brush plate.

[0015] Preferably, a scraper is installed on the surface of the ventilation hood, wherein the scraper assists in the use of the brush plate.

[0016] The effect achieved by the above components is as follows: by setting up the scraper, when the brush plate is raised and lowered, the scraper will come into contact with the bristles on the brush plate, thereby removing the impurities and dust attached to the bristles, thus ensuring the cleaning effect of the brush plate.

[0017] Preferably, a positioning plate is mounted on the surface of the servo motor, and a stop bar is mounted on one side of the brush plate, wherein the positioning plate abuts against the stop bar.

[0018] The effect achieved by the above components is as follows: by the contact setting between the positioning plate and the stop bar, the stop bar comes into contact with the positioning plate when the brush plate rises with the toothed plate, so that the toothed plate is not easy to detach from the limit bar, thus ensuring the normal use of the component.

[0019] Preferably, a laser cutting machine is suitable for any one of the dust covers mentioned above.

[0020] The beneficial effects of this utility model are:

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1 and Figure 2 The dust cover and laser cutting machine shown include a dust cover body 1, guide rails on both sides of the surface of the cutting machine body 2, wherein the dust cover body 1 is connected by a dust cover cloth 101 and a number of skeleton plates 102, and a ventilation device 3 is provided on the surface of the dust cover body 1, wherein the ventilation device 3 assists the stable use of the dust cover body 1 with the help of a vent pipe 32, and an auxiliary component 4 is installed on the surface of the vent 33.

[0031] Figures 1-4 The ventilation device 3 shown includes a mounting frame 31, wherein the two sides of the surface of the mounting frame 31 are respectively connected to the surface of the dust cover body 1 and the surface of the cutting machine body 2. A ventilation pipe 32 is provided on the surface of the mounting frame 31, and a ventilation cover 33 is fixedly connected to the other end of the ventilation pipe 32. A filter screen 34 is fixedly connected to the surface of the ventilation cover 33. When the dust cover body 1 is installed on the slide rails on both sides of the cutting machine body 2, the dust cover body 1 extends during the processing, and the ventilation covers 33 on both sides will be connected to ensure the flow of gas. Thus, the gas enters the ventilation pipe 32 through the ventilation cover 33, and finally enters the cavity of the dust cover body 1 through the mounting frame 31. The filter screen 34 on the surface of the ventilation cover 33 will intercept external impurities and dust, ensuring that the slide rail is not easily corroded or damaged by impurities.

[0032] Figures 1-4The ventilation hood 33 shown has gears 42 rotatably mounted on both sides of its surface, and a servo motor 41 is mounted on one side of the ventilation hood 33. The output end of the servo motor 41 is connected to the gears 42 via a coupling. Two limit rods 43 are mounted on the surface of the cutting machine body 2. A toothed plate 44 is slidably mounted on the surface of the limit rod 43. The toothed plate 44 meshes with the gears 42. A brush plate 45 is mounted on the surface of the toothed plate 44. When the dust cover body 1 is folded into a folded state, the gas in the cavity of the dust cover body 1 is discharged outward. Then, the servo motor 41 on the ventilation hood 33 is started, thereby driving the rotation of the gears 42. Because the toothed plate 44 is slidably limited by the limit rods 43 on the cutting machine body 2, the toothed plate 44 moves up and down with the gears 42, thereby driving the brush plate 45 to slide and rub against the surface of the filter screen 34. Thus, the dust and impurities on the surface of the filter screen 34 are removed by the brush plate 45 and the exhaust, thereby ensuring the normal use of the ventilation device 3.

[0033] Figures 1-4 The auxiliary component 4 shown also includes a stabilizing bar 49 installed between the two toothed plates 44. The stabilizing bar 49 enhances the stability of the toothed plates 44 during operation. By setting the stabilizing bar 49, the toothed plates 44 on both sides of the brush plate 45 can form a certain connection, thereby better ensuring stable and synchronous movement, and thus ensuring the stable use of the brush plate 45. A scraper 46 is installed on the surface of the ventilation hood 33. The scraper 46 assists in the use of the brush plate 45. By setting the scraper 46, when the brush plate 45 is raised and lowered, the scraper 46 will come into contact with the bristles on the brush plate 45, thereby removing impurities and dust attached to the bristles, thus ensuring the cleaning effect of the brush plate 45.

[0034] Figures 1-4 A positioning plate 47 is mounted on the surface of the servo motor 41 shown, and a stop bar 48 is mounted on one side of the brush plate 45. The positioning plate 47 abuts against the stop bar 48. Through the abutment setting of the positioning plate 47 and the stop bar 48, when the brush plate 45 rises with the toothed plate 44, the stop bar 48 contacts the positioning plate 47, so that the toothed plate 44 is not easy to detach from the limit rod 43, ensuring the normal use of the component.

[0035] Working principle: When the dust cover body 1 is installed on the slide rails on both sides of the cutting machine body 2, the dust cover body 1 extends during processing, connecting the ventilation covers 33 on both sides, ensuring gas flow. Gas then passes through the ventilation covers 33 into the ventilation pipe 32, and finally enters the cavity of the dust cover body 1 through the mounting frame 31. The filter screen 34 on the surface of the ventilation cover 33 intercepts external impurities and dust, ensuring the slide rails are not easily corroded or damaged by impurities. When the dust cover body 1 retracts to form a folded state... The gas in the cavity of the dust cover body 1 is discharged outward, and then the servo motor 41 (model SGM7A) on the ventilation cover 33 is started, thereby driving the rotation of the gear 42. Because the toothed plate 44 is slidably limited by the limit rod 43 on the cutting machine body 2 (model SP-DOG), the toothed plate 44 moves up and down with the gear 42, thereby driving the brush plate 45 to slide and rub against the surface of the filter screen 34. Thus, the dust and impurities on the surface of the filter screen 34 are removed by means of the brush and exhaust, thereby ensuring the normal use of the ventilation device 3.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
