[0002] A laser cutting machine is a machine used for laser cutting of materials such as sheet metal. Existing laser cutting machines have a frame at the cutting station, with a protective plate installed on the frame. One end of the frame has an opening with a sliding door. After the sliding door is opened, maintenance personnel can enter the cutting station to inspect and repair the equipment.

[0003] Existing sliding doors move horizontally in a straight line during use. After moving to the target position, the door body is not aligned with the side protective panels and is misaligned, leaving a gap between the door body and the side protective panels. This gap can easily lead to the risk of laser leakage during the panel cutting process. Utility Model Content

[0004] Based on this, a sliding door for a laser cutting machine is provided. After the sliding door is moved to the target position, it can remain flush with the side panels, thus avoiding gaps caused by misalignment and helping to prevent the risk of laser leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 3 As shown, an embodiment of this application provides a sliding door for a laser cutting machine. The sliding door includes a frame 101 and a door body 102. A handle 103 is provided on the door body 102. A first support platform 104 is provided on the top of the frame 101. Two top guide rails 105 are spaced apart on the first support platform 104. Each top guide rail 105 includes a straight portion 1051 and an arc-shaped portion 1052. The arc-shaped portion 1052 extends toward the inside of the frame 101. Each top guide rail 105 is provided with a moving block assembly 106 that rolls with the top guide rail 105. The moving block assembly 106 is provided with a rotating assembly 107. The application also includes a top connecting plate 111. The top connecting plate 111 is connected to the rotating assembly 107 provided on the moving block assembly 106 on each top guide rail 105. The top connecting plate 111 is also connected to the upper part of the door body 102.

[0037] Specifically, the frame 101 is provided with a guard plate 108 and an opening, and a door 102 is provided at the opening to close it. When moving, the door 102 can first move in a straight line, and then move towards the frame 101 via the arc-shaped part 1052 of the guide rail. After reaching the target position, the door 102 is flush with the guard plates 108 on both sides. When the door 102 needs to be opened, the operator uses the handle 103 on the door 102 to move the door 102 outwards from the frame 101, and then moves the door 102 in a straight line. This moves the door 102 to the front of one of the guard plates 108. At this time, the opening on the frame 101 is not closed by the door 102, and the operator enters the interior of the frame 101 through this opening.

[0038] Specifically, such as Figure 2 As shown, the frame 101 is also provided with a vertically arranged limiting plate 109 located on one side of the guard plate 108. The limiting plate 109 is used to limit the door 102. After the door 102 moves to the target position, the door 102 is limited by the limiting plate 109 and cannot move further.

[0039] Specifically, such as Figure 3As shown, since the guide rail includes a straight section 1051 and an arc section 1052, in order to make the door 102 move smoothly, the moving block assembly 106 of this application is provided with a rotating assembly 107. The rotating assembly 107 is connected to the top connecting plate 111, and the top connecting plate 111 is connected to the door 102. This makes the door 102 move very smoothly along the guide rail without getting stuck.

[0040] In one embodiment, such as Figure 4 As shown, a second support platform 114 is provided at the bottom of the frame 101, and a bottom guide rail 115 is provided on the second support platform 114. The bottom guide rail 115 includes a straight part 1051 and an arc-shaped part 1052. The arc-shaped part 1052 extends toward the inside of the frame 101. A moving block assembly 106 is provided on the bottom guide rail 115 and rolls with it. A rotating assembly 107 is provided on the moving block assembly 106. The bottom connecting plate 112 is also included. The bottom connecting plate 112 is connected to the rotating assembly 107 on the moving block assembly 106 on the bottom guide rail 115. The bottom connecting plate 112 is connected to the lower part of the door body 102.

[0041] Specifically, the top and bottom of the door 102 are guided by corresponding guide rails, which facilitates the smoother and more stable movement of the door 102.

[0042] In one embodiment, such as Figure 5 As shown, the top connecting plate 111 includes a first horizontal portion 1111 and a first vertical portion 1112. The first vertical portion 1112 is connected to the door body 102 by bolts, and the first horizontal portion 1111 is connected to a rotating assembly 107 provided on a moving block assembly 106 on each top guide rail 105. Such a top connecting plate 111 has a simple structure and is easy to install.

[0043] Similarly, the bottom connecting plate 112 includes a second horizontal part 1121 and a second vertical part 1122. The second vertical part 1122 is connected to the door body 102, and the second horizontal part 1121 is connected to the rotating component 107 on the moving block assembly 106 on the bottom guide rail 115.

[0044] In one embodiment, such as Figure 1 As shown, a limit block 110 is provided on the straight section 1051 of one of the top guide rails 105. When the corresponding moving block assembly 106 comes into contact with the limit block 110, the door body 102 cannot continue to move.

[0045] Specifically, when the door 102 moves, after the moving block assembly 106 contacts the limiting block 110, the moving block assembly 106 cannot continue to move, thus preventing the door 102 from moving further. This prevents the moving block assembly 106 from detaching from the guide rail.

[0046] Specifically, in one embodiment, the movable block assembly 106 includes a base 118 and a plurality of rollers 119 disposed on the base 118. For example, four rollers 119 are disposed at the bottom of the base 118, and the rollers 119 are fixed to the base 118 by bolts and nuts. Grooves for cooperating with the rollers 119 are respectively provided on both sides of the guide rail.

[0047] Based on the above, such as Figures 6 to 9 As shown, in one embodiment, the rotating assembly 107 includes a bearing housing 120 bolted to the base 118, a bearing 121 mounted in the bearing housing 120, a shaft 122 connected to the bearing 121, a bushing 123 sleeved on the shaft 122, and a bearing baffle 124 bolted to the bearing housing 120.

[0048] Furthermore, the top connecting plate 111 is connected to the shaft 122 on the corresponding rotating assembly 107 by bolts. Similarly, the bottom connecting plate 112 is connected to the shaft 122 on the corresponding rotating assembly 107 by bolts.

[0049] In one embodiment, such as Figure 10 As shown, the door body 102 has an opening, and four glass pressure plates 116, bolted to the door body 102, are arranged circumferentially around the opening. An annular baffle 117 is also provided at the opening, and a glass plate 113 is fixed between the annular baffle 117 and each glass pressure plate 116. This arrangement facilitates the fixing and replacement of the glass plates 113. For example, when the glass plate 113 needs to be replaced, the glass pressure plate 116 is separated from the door body 102, the glass plate 113 is replaced, and then the glass pressure plate 116 is reconnected to the door body 102, securing the new glass plate 113. The glass plates 113 are used by operators to observe the various mechanisms inside the frame 101.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
