Description

Technical Field

[0001] This utility model relates to the technical field of glass waterjet cutting machines, specifically an improved splash guard for glass waterjet cutting machines. Background Technology

[0002] A waterjet cutter, also known as a water jet cutter or high-pressure water jet cutter, is a machine that uses high-speed jets of water mixed with sand as a medium to cut glass. When a waterjet cutter cuts glass, it generates a large amount of wastewater and debris, including sand and glass shards. Furthermore, the high-pressure water jets from the cutter head often splash everywhere during the cutting process.

[0003] For example, Chinese invention patent CN220922905U, published on May 10, 2024, discloses a glass waterjet cutting machine, including a cutting machine body and a worktable. The worktable is fixedly connected to the lower part of the cutting machine body, and an anti-slip pad is fixedly connected to the surface of the worktable. Glass is placed on the upper part of the anti-slip pad. A fixing block is fixedly connected to the upper part of the cutting machine body, and a waterjet is fixedly connected to the lower end of the fixing block. Mounting blocks are fixedly connected to both sides of the fixing block by bolts. The mounting block is rotatably connected to a sleeve through a rotating shaft. A through hole is opened in the upper part of the sleeve, and a movable rod is slidably connected inside the sleeve. A limiting bracket is fixedly connected to the lower end of the movable rod, and the lower part of the limiting bracket is engaged with the limiting block. A splash guard is fixedly connected to the bottom of the limiting block. In this invention, the splash guard can block the debris and water droplets splashed around when the waterjet cutting machine cuts glass, thus not affecting the operator's work.

[0004] As can be seen from the above patents, the splash guard can block debris and water droplets splashing from all directions. However, the presence of the splash guard can cause debris and wastewater to easily accumulate inside, hindering their discharge and affecting glass cutting. Therefore, this invention provides an improved splash guard for a glass waterjet cutting machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an improved splash guard for glass waterjet cutting machines.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved splash guard for a glass waterjet cutting machine includes a cutting machine body, a splash guard, and glass. A fixing block is fixedly connected to the upper part of the cutting machine body, and a sleeve is fixedly connected to the lower end of the fixing block. An electric telescopic rod is fitted inside the sleeve and is slidably connected to the sleeve. The bottom end of the electric telescopic rod is fixedly connected to the waterjet. The splash guard includes four splash guards (front, rear, left, and right) symmetrically designed along the central axis of the waterjet. The splash guard is fixedly connected to the outer wall of the sleeve by bolts to form a sealed structure. The splash guard includes an inner cover and an outer cover. A rotating shaft is provided at the bottom of the inner cover, and a brush roller is fitted on the rotating shaft. A protective cover is provided on 1 / 4 of the circumference of the brush roller.

[0008] Preferably, a motor is provided on the bottom side of the inner cover, the output mechanism of the motor is fixedly connected to the rotating shaft through a coupling, and the motor is electrically connected to the control unit of the cutting machine.

[0009] Preferably, the top center of the outer cover has an air inlet, which is connected to an air compressor via a high-pressure pipe, and the bottom of the outer cover is connected to a guide plate, which is arc-shaped.

[0010] Preferably, the outer wall of the rotating shaft and the inner wall of the brush roller are both provided with grooves of equal width and height. The brush roller is sleeved on the rotating shaft and is detachably connected by inserting wedges of appropriate specifications into the grooves.

[0011] Preferably, the outer wall of the brush roller is evenly covered with bristles, and the bristles are attached to the protective cover.

[0012] Preferably, a gas distributor is provided below the air inlet.

[0013] The beneficial effects of this utility model are:

[0014] This design employs a double-layered structure with an inner and outer cover. A brush roller cleans debris and wastewater from the inner cover, while high-pressure gas and a guide plate blow the debris and wastewater out of the splash guard, further dispersing debris and wastewater from the glass surface to facilitate glass cutting. This invention solves the problem of debris and wastewater accumulating inside the splash guard and hindering glass cutting, enabling timely discharge of debris and wastewater from the splash guard and facilitating the cleaning of debris and wastewater from the glass surface.

[0030] Reference Figure 1-5 The present invention discloses an improved splash guard for a glass waterjet cutting machine, comprising a cutting machine body 1, a splash guard 2 and glass 3; wherein the splash guard 2 includes an inner cover 21, an outer cover 22, a rotating shaft 23, a brush roller 24, a protective cover 25, a motor 26, an air inlet 27, a guide plate 28 and a gas distributor 29.

[0031] The cutting machine body 1 is provided with a fixing block 11, a sleeve 12, an electric telescopic rod 13, and a water jet 14 arranged sequentially from top to bottom. The fixing block 11 is used to fix and connect the cutting machine body 1. The electric telescopic rod 13 is fitted and slidably connected inside the sleeve 12, which is fixedly connected to the lower end of the fixing block 11. The electric telescopic rod 13 is a mature existing technology and will not be described in detail here. The bottom end of the electric telescopic rod 13 is fixedly connected to the water jet 14, so the height of the water jet 14 can be adjusted by extending and shortening the electric telescopic rod 13, which facilitates the cutting of the glass 3.

[0032] The splash guard 2, used to shield debris and water droplets splashing from all directions, includes four splash guards: front, rear, left, and right, symmetrically designed along the central axis of the water jet 14. The splash guard 2 is fixedly connected to the outer wall of the sleeve 12 by bolts to form a sealed structure. The splash guard 2 includes an inner cover 21 and an outer cover 22. The inner cover 21 can shield the debris and water droplets splashing from all directions within the inner cover 21 and clean the debris and wastewater out of the inner cover 21. The outer cover 22 can use gas to blow the debris and wastewater flowing out of the inner cover 21 out of the outer cover 22 and continue to blow along the surface of the glass 3, so as to facilitate the timely cleaning of debris and wastewater and the cutting of the glass 3. The bottom of the inner cover 21 is provided with a rotating shaft 23 and a motor 26. The motor 26 is electrically connected to the cutting machine control unit. The output mechanism of the motor 26 is fixedly connected to the rotating shaft 23 through a coupling. The cutting machine control unit turns on the motor 26, and the output mechanism of the motor 26 drives the rotating shaft 23 to rotate. A brush roller 24 is sleeved on the rotating shaft 23. The rotating rotating shaft 23 can drive the brush roller 24 to rotate, which can clean the debris and wastewater inside the inner cover 21 to the outside of the inner cover 21.

[0033] In an optional embodiment, the outer wall of the brush roller 24 is uniformly and densely covered with bristles, and a protective cover 25 is provided on 1 / 4 of the circumference of the brush roller 24, with the bristles adhering to the protective cover 25. The protective cover 25 can scrape off the debris and wastewater adhering to the bristles on the brush roller 24 to prevent it from affecting the normal use of the brush roller 24; on the other hand, the protective cover 25 can block the air inside the outer cover 22 from blowing towards the brush roller 24 to prevent it from affecting the normal use of the brush roller 24.

[0034] In an optional embodiment, an air inlet 27 is provided at the top center of the outer casing 22. The air inlet 27 is connected to an air compressor (not shown in the figure) via a high-pressure pipe, and high-pressure gas supplied by the air compressor enters the outer casing 22 through the high-pressure pipe from the air inlet 27. A gas distributor 29 is provided below the air inlet 27 to distribute the incoming high-pressure gas evenly within the outer casing 22. An arc-shaped guide plate 28 is connected to the bottom of the outer casing 22. The guide plate 28 deflects the high-pressure gas from top to bottom to a direction parallel to the glass 3, so as to blow out the debris and wastewater flowing out of the inner casing 21 from the splash guard 2, and continue to disperse the debris and wastewater on the surface of the glass 3 to facilitate cutting the glass 3.

[0035] In an optional embodiment, grooves of equal width and height are provided on the outer wall of the rotating shaft 23 and the inner wall of the brush roller 24. The brush roller 24 is sleeved on the rotating shaft 23 and is detachably connected by inserting wedges of appropriate specifications into the grooves.

[0036] The workflow of this utility model is as follows:

[0037] When the cutting machine control unit controls the water jet 14 to start cutting the glass 3, the cutting machine control unit simultaneously turns on the motor 26 and the air compressor. The motor 26 drives the rotating shaft 23, which in turn drives the brush roller 24 to rotate, cleaning the debris and wastewater inside the inner cover 21 out of the inner cover 21. The high-pressure gas output by the air compressor enters the outer cover 22 through the high-pressure pipe from the air inlet 27. After passing through the gas distributor 29, it is evenly distributed in the outer cover 22. After flowing from top to bottom to the protective cover 25 and the guide plate 28, the gas blows the debris and wastewater flowing out of the inner cover 21 out of the splash shield 2 along a direction parallel to the glass 3, and continues to blow away the debris and wastewater on the surface of the glass 3 to facilitate the cutting of the glass 3.

[0038] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail.

[0039] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
