[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] To address the technical problem of inconvenient disassembly of the cabinet door that obstructs the belt drive mechanism on a rice polishing machine, this utility model provides a cabinet device and polishing machine that can obstruct the belt drive mechanism while also facilitating disassembly.

[0039] It should be noted that the cabinet device described in this utility model is used in, but not limited to, rice polishing machines. For ease of explanation, this utility model only uses the cabinet door device applied to a rice polishing machine as an example. The principle of the cabinet door device applied to other types of equipment is essentially the same as that applied to a rice polishing machine, and will not be described in detail here.

[0040] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a polishing machine when disassembling the cabinet door in one embodiment of the present invention. A cabinet door device is configured on the frame 1 connected to the polishing machine, including a cabinet door assembly 2 and at least two hook assemblies 3. The cabinet door assembly 2 includes a cabinet door piece 21 and a limiting piece 22. The limiting piece 22 is connected to the cabinet door piece 21 and is disposed on the edge of the cabinet door piece 21. The limiting piece 22 is disposed against the frame 1 to restrict the cabinet door piece 21 from sliding relative to the frame 1 in the vertical direction. At least two hook assemblies 3 are respectively disposed on both sides of the cabinet door piece 21. The hook assembly 3 is configured to be connected to one of the cabinet door piece 21 and the frame 1 and is detachably hung on the other one.

[0041] When it is necessary to cover the components on the rack 1 through the cabinet door 211, the cabinet door 21 is positioned relative to the rack 1, and the limiting member 22 abuts against the rack 1. At this time, the limiting member 22 can restrict the cabinet door 21 from sliding relative to the rack 1 in the vertical direction. Then, the cabinet door 211 is connected to the rack 1 through the hook assembly 3 on both sides of the cabinet door 21 to restrict the cabinet door 21 from moving in the direction away from the rack 1. The connection between the cabinet door 21 and the rack 1 is achieved through the hook assembly 3 and the limiting member 22. When installing and removing the cabinet door 211, only the hook needs to be pulled, making installation and removal convenient.

[0042] It should be understood that the hook assembly 3 can be hung on the cabinet door 211 or on the rack 1, and holes or hanging rings for hook hanging can be provided on the cabinet door 211. Specifically, in one embodiment, such as Figure 5 and Figure 6 As shown, in one embodiment, the cabinet door component 21 includes a cabinet door 211 and at least two bent portions 212. The at least two bent portions 212 are disposed on both sides of the cabinet door 211. The bent portions 212 are connected to the cabinet door 211 and are disposed on the side of the cabinet door 211 away from the frame 1, and are set at an angle to the cabinet door 211. The hook assembly 3 is disposed connected to the frame 1 and is detachably hung on the bent portions 212.

[0043] When it is necessary to fix the cabinet door 211 to the frame 1, the hook assembly 3 is hung on the bent part 212 on the cabinet door 211, thereby fixing the cabinet door 211 relative to the frame 1. By setting the bent part 212, there is no need to drill holes or set up hanging rings on the cabinet door 211 for the hook assembly 3 to hang.

[0044] It should be understood that the bent portion 212 can be a baffle or edge formed by bending the cabinet door 211, for example, Figure 5 and Figure 6 As shown, in one embodiment, the bending portion 212 includes a first fold plate 2121 and a second fold plate 2122 formed by bending. One side of the first fold plate 2121 is connected to the cabinet door 211, and one side of the second fold plate 2122 is connected to the other side of the first fold plate 2121. The other side of the second fold plate 2122 is disposed facing the cabinet door 211. The hook assembly 3 is detachably hung at the connection between the second fold plate 2122 and the first fold plate 2121.

[0045] In this embodiment, by bending the edges of the cabinet door 211 on both sides, a first folding plate 2121 and a second folding plate 2122 are formed. The side of the bent portion 212 away from the cabinet door 211 is the connection point between the second folding plate 2122 and the first folding plate 2121. The smooth transition here can prevent the sharp edges of the cabinet door 211 from being exposed. At the same time, the smooth transition connection point can also be used for the hook assembly 3 to hang.

[0046] It should be understood that the cabinet door component 21 can be a single door panel, or multiple cabinet door components 21 can be provided. Specifically, for example... Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, there are multiple cabinet door components 21, which are stacked and abut against each other, and each cabinet door component 21 has at least two hook assemblies 3 on both sides.

[0047] In this embodiment, multiple cabinet door components 21 are set to cover the position where the belt drive mechanism 5 is installed on the frame 1. When it is necessary to observe the belt slack in the belt drive mechanism 5, only the corresponding cabinet door component 21 needs to be removed. Moreover, when installing and removing the cabinet door component 21, multiple cabinet door components 21 can be installed in sequence to avoid the large weight of the entire cabinet door component 21 affecting the installation.

[0048] It should be understood that the number of cabinet door components 21 can be one, two, or three, etc., specifically, as shown in the example below. Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, there are two cabinet door components 21 and two limiting components 22. The two limiting components 22 are respectively disposed on the two cabinet door components 21, and are disposed on the opposite side of the two cabinet door components 21. The limiting component 22 is a baffle formed by bending the cabinet door component 21. The upper limiting component 22 is disposed on the frame 1 and the lower limiting component 22 is disposed on the frame 1. Each cabinet door component 21 is provided with a hook assembly 3 on both sides.

[0049] In this embodiment, the number of cabinet door components 21 is set to two. The two cabinet door components 21 are stacked together. The upper limiting component 22 is configured to hang on the frame 1, so that the upper cabinet door component 21 is hung on the frame 1 under the action of the limiting component 22. The lower limiting component 22 is configured to abut against the frame 1, so that the lower limiting component 22 abuts against the bracket, and the lower cabinet door component 21 is supported by the limiting component 22 and the bracket. The two limiting components 22 limit the vertical movement of the two cabinet door components 21.

[0050] To facilitate support between two adjacent cabinet doors 211, therefore, as Figure 7 and Figure 8 As shown, in one embodiment, the two cabinet doors 211 of the two cabinet door components 21 are bent on opposite sides to form a third folding plate 213. The third folding plate 213 is formed by bending the cabinet doors 211 toward the direction of the frame 1, and the two cabinet doors 211 abut against each other through the third folding plate 213.

[0051] By setting the third folding plate 213, the contact area when the two cabinet doors 211 abut is increased, which avoids the cabinet doors 211 sliding relative to the frame 1 due to misalignment during installation.

[0052] It should be understood that the hook assembly 3 can be a hinged hook or a flexible hook, specifically, such as Figure 2 and Figure 3 As shown, in one embodiment, the hook assembly 3 includes a fixed base 31, an elastic element 32, and a hook 33. The fixed base 31 is disposed on the frame 1, and the hook 33 is connected to the fixed base 31 via the elastic element 32. The hook 33 is detachably hung on the cabinet door component 21.

[0053] When hook 33 assembly 3 is attached to cabinet door 21, hook 33 is pulled, hook 33 stretches elastic member 32, and then hook 33 is attached to the bent part 212 of cabinet door 21. When hook 33 is released, hook 33 is driven to return to its original position under the action of elastic member 32, so that hook 33 is firmly attached to bent part 212 and provides elastic force for cabinet door 211 to adhere tightly to frame 1.

[0054] In order to facilitate the hook 33 to be hung on the bent part 212, in one embodiment, the elastic element 32 is hinged to the fixed base 31, and the hook 33 is hinged to the elastic element 32.

[0055] In this embodiment, by hinged elastic element 32 to fixed base 31 and by hinged hook 33 to elastic element 32, hook 33 can rotate relative to fixed base 31 and elastic element 32, making it convenient to hang hook 33 on bending part 212.

[0056] It should be understood that the elastic element 32 can be a spring, an elastic rope, or an elastic block, etc. Specifically, such as Figure 2 and Figure 3 As shown, in one embodiment, the elastic member 32 includes a first connecting portion 321, a second connecting portion 322, and a spring 323. One end of the first connecting portion 321 is hinged to the fixed base 31, and the other end of the first connecting portion 321 forms a first limiting block 324. One end of the second connecting portion 322 is hinged to the hook 33, and the other end of the second connecting portion 322 forms a second limiting block 325. The spring 323 is sleeved on the first connecting portion 321 and the second connecting portion 322, with one end of the spring 323 abutting against the first limiting block 324 and the other end abutting against the second limiting block 325.

[0057] In this embodiment, when the hook 33 is stretched, the hook 33 drives the second connecting part 322 to move. The second connecting part 322 compresses the spring 323 through the second limiting block 325. Under the combined action of the second limiting block 325 and the first limiting block 324, the spring 323 is compressed. The spring 323 accumulates elastic restoring force. When the hook 33 is released, the spring 323 pushes the second limiting block 325 and the second connecting part 322 to move. The second connecting part 322 drives the hook 33 to be hung on the bent part 212.

[0058] It should be understood that the first connecting part 321 and the second connecting part 322 are connecting strips, connecting rods, and connecting blocks, etc.

[0059] It should be understood that the number of elastic elements 32 can be one, two, or more, for example, Figure 2 and Figure 3 As shown, in one embodiment, there are two elastic elements 32, which are spaced apart on both sides of the fixed base 31. The second connecting part 322 of the two elastic elements 32 is hinged to the hook 33 by a pivot pin 34.

[0060] Secondly, this utility model also provides a polishing machine, including the aforementioned cabinet door device.

[0061] In order to shield the area on frame 1 where the motor 4 and belt drive mechanism 5 are mounted, therefore, as follows: Figure 1 As shown, in one embodiment, the polishing machine further includes a frame 1, which forms an installation space for mounting a power supply 4 and a belt drive mechanism 5, with an opening on one side of the installation space; the cabinet door 21 is disposed opposite to the opening of the installation space; the limiting member 22 abuts against the frame 1; and the hook 33 assembly 3 is connected to the frame 1 and detachably hung on the cabinet door 21.

[0062] In this embodiment, the cabinet door component 21 is positioned relative to the opening of the installation space. The cabinet door component 21 covers the opening of the installation space, preventing the rotating belt drive mechanism 5 from threatening the safety of the workers. When fixing the cabinet door component 21, the upper cabinet door component 21 is hung on the top of the frame 1 by the limiting component 22, and the lower cabinet door component 21 is supported on the crossbeam at the bottom of the frame 1 by the limiting component 22. Then, the hook 33 is hung on the bent parts 212 on both sides of the cabinet door 211, so that the cabinet door 211 is fixed to the frame 1. When installing and removing the cabinet door 211, only the hook 33 needs to be operated, making installation and removal convenient.

[0063] It should be understood that the belt drive mechanism 5 includes multiple pulleys 51 and a belt 52. The multiple pulleys 51 are respectively sleeved on the main shaft of the polishing machine (not shown in the figure) and the output shaft of the motor 4, and the belt 52 is sleeved on the pulleys 51 and the output shaft of the motor 4.

[0064] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
