[0026] In the current technology, cleaning rollers are generally used to clean conveyor belts. The cleaning rollers are consumables and need to be cleaned after a period of use. However, the cleaning rollers are very inconvenient to disassemble, which affects the cleaning effect.

[0027] This utility model proposes a cleaning mechanism.

[0028] Please see Figures 1 to 5 In one embodiment of this utility model, the cleaning mechanism includes: a first cleaning roller 100, a bracket 200, a mounting block 300, and a positioning member 400; wherein, the first cleaning roller 100 is used to remove debris from the component to be cleaned, and mounting portions 110 are respectively provided at both ends of the first cleaning roller 100; the bracket 200 is fixedly connected to the component to be cleaned; the mounting block 300 is fixedly connected to the bracket 200, and the mounting block 300 has a mounting groove 310 for accommodating the mounting portion 110 and a positioning hole 320 communicating with the mounting groove 310, the groove opening 311 of the mounting groove 310 faces the side of the mounting block 300, and the mounting portion 110 enters the mounting groove 310 from the groove opening 311; the positioning member 400 is connected to the positioning hole 320, and one end of the positioning member 400 extends into the mounting groove 310 and movably abuts against the mounting portion 110.

[0029] It should be noted that the component to be cleaned can be a conveyor belt 600 mechanism or a conveyor roller mechanism, etc. Taking the conveyor belt 600 mechanism as an example, the outer periphery of the first cleaning roller 100 contacts the surface of the conveyor belt 600 to remove debris from the conveyor belt surface, thus achieving a cleaning effect. It should also be noted that the bracket 200 is fixedly connected to the wire frame of the conveyor belt 600 mechanism, serving as a mounting support, allowing the entire cleaning mechanism to be installed on the conveyor belt 600 mechanism. Furthermore, to facilitate the replacement of the cleaning mechanism, in specific implementations, the cleaning mechanism is located at the bottom of the conveyor belt 600 mechanism near its end, with the first cleaning roller 100 located at the bottom of the conveyor belt 600 and in contact with its surface. The first cleaning roller 100 can clean debris from the surface of the conveyor belt 600 by adhering to it or by suction; this is not limited in this embodiment.

[0030] refer to Figure 2 and Figure 3 As shown, the first cleaning roller 100 has mounting portions 110 on its side walls near both ends. It can be understood that both sides of the component to be cleaned are provided with brackets 200, mounting blocks 300, and positioning elements 400 corresponding to the mounting portions 110. In specific implementation, the brackets 200 are fixedly mounted on the hook to be cleaned, and the mounting blocks 300 are fixedly mounted on the brackets 200. The first cleaning roller 100 is detachably connected to the mounting blocks 300 via the mounting portions 110 and positioned by the positioning elements 400. Specifically, the mounting blocks 300 can be locked to the brackets 200 on opposite sides using connecting bolts. A mounting groove 310 is formed on one side wall of the mounting block 300 and extends towards the opposite side wall. Thus, the groove 311 is located on one side of the mounting block 300, facilitating the assembly and disassembly of the first cleaning roller 100 and enabling quick assembly and disassembly.

[0031] The mounting part 110 engages with the inner wall of the mounting groove 310 and slides along the inner wall of the mounting groove 310 into the mounting groove 310. A positioning hole 320 extends vertically and communicates with the mounting groove 310. A positioning member 400 is threadedly connected to the positioning hole 320, and its end extends into the mounting groove 310 to abut against the mounting part 110, thus positioning the mounting part 110. To improve the stability of the first cleaning roller 100, in this embodiment, the mounting block 300 has two positioning holes 320 that communicate and penetrate the mounting block 300. Correspondingly, two positioning members 400 are provided, each connected from the top and bottom surfaces of the mounting block 300 to the corresponding positioning hole 320, and the ends of the two positioning members 400 abut against the mounting part 110 of the first cleaning roller 100. The positioning element 400 can be a positioning pin or an elastic pin, etc., and its end abuts against the mounting part 110. Pulling the first cleaning roller 100 can make the mounting part 110 slide along the end of the positioning element 400, so that it can smoothly leave or abut against the positioning element 400.

[0032] This utility model's technical solution employs an installation groove 310 on one side of the installation block 300 to accommodate the installation part 110, with the groove opening 311 of the installation groove 310 facing the side of the installation block 300. Installation parts 110 are provided at both ends of the first cleaning roller 100. When installing the first cleaning roller 100, the installation part 110 enters the installation groove 310 from one side of the installation block 300 through the groove opening 311. The installation block 300 also has a positioning hole 320 communicating with the installation groove 310. A positioning member 400 is provided in the positioning hole 320, with one end extending into the installation groove 310 and movably abutting against the installation block 300 located within the installation groove 310, thereby achieving the installation and positioning of the installation block 300. Pulling the first cleaning roller 100 in the opposite direction releases the mounting part 110 from the abutting connection with the positioning member 400 and removes it from the installation groove 310, thus achieving the disassembly of the first cleaning roller 100. The cleaning mechanism proposed in this technical solution pushes the first cleaning roller 100 so that the mounting part 110 enters the mounting groove 310 from the groove opening 311. Installation is achieved by the positioning member 400 abutting and positioning. The first cleaning roller 100 is pulled towards the groove opening 311 to disconnect from the positioning member 400 and leave the mounting groove 310 for disassembly. In this way, the installation and disassembly of the first cleaning roller 100 are very convenient and quick, which can improve the cleaning effect while improving production efficiency.

[0033] refer to Figure 4 As shown, in one embodiment, the positioning member 400 includes a movable part 410, an elastic part 420 and a connecting part 430. The elastic part 420 is connected to the movable part 410 and the connecting part 430 respectively. The connecting part 430 is connected to the positioning hole 320. The movable part 410 is used to abut against the mounting part 110.

[0034] In the specific implementation process, the elastic part 420 is connected to the movable part 410 and the connecting part 430 respectively. On the one hand, the elastic member 232 drives the movable part 410 to move towards the mounting part 110 and then press against the mounting part 110. On the other hand, the elastic part 420 can be compressed, which makes it easier for the mounting part 110 to enter and leave the mounting groove 310.

[0035] Furthermore, the mounting part 110 is provided with a positioning groove 111, and the movable part 410 engages and abuts within the positioning groove 111. In this embodiment, the positioning groove 111 is recessed, and the movable part 410 engages with the positioning groove 111 to push the first cleaning roller 100 so that the positioning groove 111 of the mounting part 110 is opposite to the movable part 410. Under the action of elastic force, the elastic part 420 drives the movable part 410 into the positioning groove 111 to engage and abut, thereby realizing the installation of the first cleaning roller 100 in place. In specific implementation, the movable part 410 is a ball bearing structure, and the elastic part 420 is a spring. The ball bearing structure can roll and contact the mounting part 110, reducing the friction between the two. At least part of the ball bearing structure is located within the positioning groove 111 to limit the displacement of the mounting part 110 and prevent the mounting part 110 from sliding within the mounting groove 310 and automatically disengaging from the mounting groove 310.

[0036] It should be noted that the outer wall of the connecting part 430 of the positioning member 400 is provided with threads and connected to the positioning hole 320. The connecting part 430 is provided with a receiving cavity and has an opening at one end. The movable part 410 is located in the receiving cavity and has a portion extending out of the receiving cavity from the opening. One end of the elastic member 232 abuts against the inner wall of the receiving cavity away from the opening, and the other end abuts against the movable part 410, so that the movable part 410 has a tendency to move away from the opening from the receiving cavity, thereby causing the movable part 410 to abut against the opening.

[0037] refer to Figure 3 As shown, in one embodiment, the mounting portion 110 is configured as a plane, and the first cleaning roller 100 is provided with two planes, which respectively cooperate and slide with the two side walls of the mounting groove 310.

[0038] In the specific implementation process, the two side walls near the end of the first cleaning roller 100 are recessed, forming two flat surfaces. These two surfaces are positioned opposite each other, and the distance between them matches the distance between the two inner walls of the mounting groove 310. This allows the first cleaning roller 100 to smoothly enter the mounting groove 310, and there is no large gap between the mounting part 110 and the inner wall of the mounting groove 310, which would affect the stability of the mounting part 110. Specifically, the mounting part 110 moves along the inner wall of the mounting groove 310 to the positioning groove 111 to engage with the movable part 410. Furthermore, the bottom surface of the mounting groove 310 is arc-shaped to match the outer wall of the first cleaning roller 100, thereby improving the stability of the first cleaning roller 100 during installation.

[0039] refer to Figure 2 As shown, in one embodiment, the bracket 200 includes a fixed block 210, a movable block 220 and an adjustment component 230. The fixed block 210 is fixedly connected to the component to be cleaned. The adjustment component 230 is connected to the movable block 220 and the fixed block 210 respectively, and makes the movable block 220 tend to move toward the fixed block 210. The mounting block 300 is fixedly connected to the movable block 220.

[0040] In this embodiment, the fixed block 210 is fixedly connected to the line frame of the conveyor belt 600 mechanism, and the movable block 220 is located below the fixed block 210 and connected to the fixed block 210 through the adjusting component 230. The adjusting component 230 is elastic to drive the movable block 220 toward the fixed block 210, thereby making the first cleaning roller 100 tend to move toward the conveyor belt 600, thus ensuring that the first cleaning roller 100 can smoothly remove debris from the surface of the conveyor belt 600.

[0041] In one embodiment, the adjustment component 230 includes a connector 231 and an elastic member 232 sleeved on the outer periphery of the connector 231. The movable block 220 has a connection channel 221. One end of the connector 231 passes through the connection channel 221 and is connected to the fixed block 210. One end of the elastic member 232 is connected to the connector 231, and the other end is connected to the movable block 220.

[0042] In the specific implementation process, the connector 231 has a bolt-like structure. The outer peripheral wall near one end is threaded and passes through the connecting channel 221 to lock onto the fixed block 210. The connector 231 and the connecting channel 221 are movably arranged. The outer sleeve of the connector 231 is fitted with an elastic element 232. The elastic element 232 can be a spring or an elastic rubber ring, etc. The elastic element 232 also abuts against the movable part and is compressed between the end of the connector 231 away from the movable block 220 and the movable block 220, so that the elastic element 232 can drive the movable block 220 to move towards the fixed block 210, thereby causing the first cleaning roller 100 to move towards the conveyor belt 600, improving the cleaning effect.

[0043] Furthermore, in order to improve the stability of the movable block 220, in this embodiment, the movable block 220 has two parallel connecting channels 221, and two connecting members 231 are provided, which are respectively movably disposed in the corresponding connecting channels 221. It can be understood that two elastic members 232 are provided, which are respectively sleeved on the two connecting members 231.

[0044] refer to Figure 5 As shown, the movable block 220 further includes a limiting channel 222 that communicates with the connecting channel 221. A platform 223 is provided between the inner wall of the limiting channel 222 and the inner wall of the connecting channel 221. A stop block 233 is provided at the end of the connector 231 away from the fixed block 210. One end of the elastic member 232 abuts against the stop block 233, and the other end abuts against the platform 223.

[0045] It should be noted that the limiting channel 222 is connected to the connecting channel 221, and the inner diameter of the limiting channel 222 is larger than the inner diameter of the connecting channel 221, so that a platform 223 is formed between the limiting channel 222 and the connecting channel 221. In order to ensure effective contact of the elastic element 232 and facilitate processing, in the specific implementation process, the limiting channel 222 and the connecting channel 221 are coaxially arranged. The stop block 233 is located outside the limiting channel 222. One end of the elastic element 232 abuts against the stop block 233, and the other end abuts against the platform 223, driving the movable block 220 to move towards the fixed block 210.

[0046] refer to Figure 1 and Figure 2 As shown, in one embodiment, the first cleaning roller 100 includes a first roller shaft 120 and a first dust removal roller 130 rotatably sleeved on the outer periphery of the first roller shaft 120. The component to be cleaned is driven to be connected to the first dust removal roller 130 and drives the first dust removal roller 130 to rotate synchronously, so that the first dust removal roller 130 sticks and removes debris from the surface of the component to be cleaned. The mounting part 110 is provided on the first roller shaft 120.

[0047] In specific implementation, a bearing is provided between the first dust removal roller 130 and the first roller shaft 120, thereby enabling the first dust removal roller 130 to rotate around the first roller shaft 120. In one embodiment, the first dust removal roller 130 includes a multi-layered dust removal film, which is used to remove debris and dust from the surface of the conveyor belt 600. The surface of the first dust removal roller 130 is in contact with the conveyor belt 600, and the rotation of the conveyor belt 600 drives the first dust removal roller 130 to rotate, thereby removing dust and debris from the surface of the conveyor belt 600.

[0048] Understandably, the dust removal film is a consumable item, and a layer needs to be peeled off after a period of use to ensure the dust removal effect. Therefore, when cleaning the first dust removal roller 130, the first cleaning roller 100 is pulled, causing the mounting part 110 to leave the mounting groove 310. After cleaning, the first cleaning roller 100 is pushed, causing the mounting part 110 to enter the mounting groove 310 from the opening 311 and be positioned against the positioning member 400. This allows for convenient and quick assembly and disassembly, facilitating operation.

[0049] In practical implementation, the surface of the conveyor belt 600 is uneven, with strip-shaped protrusions that increase friction. These protrusions form recessed gaps that easily trap dust and debris. In one embodiment, the cleaning mechanism further includes a second cleaning roller 500. The support 200 includes a connecting block 240. The second cleaning roller 500 is rotatably connected to the connecting block 240. The outer circumferential surface of the second cleaning roller 500 contacts and connects to the component to be cleaned and the first dust removal roller 130, respectively. The component to be cleaned drives the first dust removal roller 130 to rotate via the second cleaning roller 500.

[0050] In this embodiment, the sidewall of the second cleaning roller 500 contacts the conveyor belt 600 and the first dust removal roller 130. The second cleaning roller 500 removes dust from the surface of the conveyor belt 600, while the first dust removal roller 130 removes dust from the second cleaning roller 500. Dust is transferred from the second cleaning roller 500 to the first dust removal roller 130, thus cleaning the first dust removal roller 130 within a certain time. Specifically, bearings are provided at both ends of the second cleaning roller 500, and the bearings are connected to the connecting block 240. In the specific implementation, the fixing block 210 of the bracket 200 has an elongated hole, through which bolts pass and connect to the connecting block 240, thereby fixing the connecting block 240. In addition, the elongated hole can also adjust the position of the connecting block 240, facilitating the adjustment of the second cleaning roller 500 to contact the conveyor belt 600 for adhering to dust and debris.

[0051] In one embodiment, the second cleaning roller 500 includes a second roller shaft 510 and a second dust removal roller 520 fixedly disposed on the outer periphery of the second roller shaft 510. The second roller shaft 510 is rotatably connected to the connecting block 240. The second roller shaft 510 is rotatably connected to the connecting block 240 through a bearing. The second dust removal roller 520 includes an adhesive for removing debris. It should be noted that the adhesive is a flexible material and has adhesive properties. During the process of the second dust removal roller 520 contacting the conveyor belt 600 and rotating, the adhesive can penetrate into the gaps of the conveyor belt 600 to remove dust and debris. Then, the debris is transferred by the adhesive film of the first dust removal roller 130, thereby improving the cleaning effect of the conveyor belt 600.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
