[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a conveyor belt cleaning device. Specifically, the conveyor belt cleaning device includes a transmission mechanism 210, a first conveyor belt 220, a first support roller 301, a second support roller 302, a conveyor belt guide and a first driving member.

[0034] like Figure 1 and Figure 2As shown, the first support roller 301 and the second support roller 302 both roll and support the side of the first conveyor belt 220 facing away from the second conveyor belt 100. The conveyor belt guide is located on the side of the second conveyor belt 100 facing away from the first conveyor belt 220, and the first drive member is connected to the conveyor belt guide. The conveyor belt guide has an arcuate protrusion. Under the action of the first drive member, the arcuate protrusion can contact and push the second conveyor belt 100 towards the first conveyor belt 220 until the arcuate protrusion presses against the first support roller 301 and the second support roller 302 through the contacting first and second conveyor belts 220, 100. The conveyor belt guide not only ensures contact between the first and second conveyor belts 220, 100, but also provides guidance for the running of the second conveyor belt 100.

[0035] In this embodiment, the first conveyor belt 220 is a cleaning belt and the second conveyor belt 100 is a transport belt. The transport belt is used to transport products and the cleaning belt is used to clean the conveyor belt. In other embodiments, the first conveyor belt 220 is a transport belt and the second conveyor belt 100 is a cleaning belt.

[0036] Hereinafter, the second conveyor belt 100 is used as a transport belt and the first conveyor belt 220 is used as a cleaning belt for explanation.

[0037] The first conveyor belt 220 is disposed on the transmission mechanism 210. The transmission mechanism 210 is used to drive the first conveyor belt 220 so that the first conveyor belt 220 travels, thereby wiping and cleaning the second conveyor belt 100 at the contact point with the second conveyor belt 100. At the contact point, the travel direction of the first conveyor belt 220 and the travel direction of the second conveyor belt 100 can be the same or opposite.

[0038] The arcuate protrusion is pressed against the first support roller 301 and the second support roller 302 through the contacting second conveyor belt 100 and the first conveyor belt 220. The circumferential surfaces of the first support roller 301 and the second support roller 302 are both approximately tangent to the arcuate protrusion, thereby providing normal support at the tangent point. The two normal supports make the positioning of the arcuate protrusion more stable, which is conducive to adjusting the contact force between the first conveyor belt 220 and the second conveyor belt 100, thereby improving the cleaning effect. Moreover, the first support roller 301 and the second support roller 302 jointly roll to support the first conveyor belt 220. The arcuate protrusion pushes the second conveyor belt 100 and presses against the first support roller 301 and the second support roller 302, so that the first conveyor belt 220 between the first support roller 301 and the second support roller 302 is in contact with the second conveyor belt 100, increasing the contact surface. Therefore, when the second conveyor belt 100 and the first conveyor belt 220 move relative to each other, the cleaning area is large, and the cleaning effect is improved.

[0039] like Figure 1 and Figure 2As shown, the first drive member optionally includes a telescopic mechanism 304 connected to the conveyor belt guide. The telescopic mechanism 304 extends and contracts perpendicular to the second conveyor belt 100, and the telescopic mechanism 304 drives the conveyor belt guide toward or away from the second conveyor belt 100. The telescopic mechanism 304 is used to move the conveyor belt guide in the vertical direction of the second conveyor belt 100, thereby achieving contact or separation between the second conveyor belt 100 and the first conveyor belt 220. When in contact, the conveyor belt cleaning device cleans the second conveyor belt 100. When separated, the conveyor belt cleaning device does not perform a cleaning function, thereby controlling the conveyor belt cleaning device to start or stop cleaning the second conveyor belt 100 as needed. The telescopic mechanism 304 is a mature technology with a simple structure and is easy to use. Exemplarily, the telescopic mechanism 304 is a linear cylinder.

[0040] like Figure 1 and Figure 2 As shown, the conveyor belt cleaning device optionally further includes a swing connector 305, through which the conveyor belt guide is connected to the telescopic mechanism 304. The provision of the swing connector 305 enables the conveyor belt guide to adaptively deflect by a certain angle according to the positions of the first support roller 301 and the second support roller 302, thereby maintaining stable contact with the first support roller 301 and the second support roller 302. In this embodiment, the swing amplitude of the swing connector 305 is no greater than 30°. This provision not only satisfies the adaptive positioning function but also prevents excessive deflection from affecting the contact effect. Specifically, the swing connector 305 may be a hinge.

[0041] like Figure 1 and Figure 2 As shown, the conveyor belt guide member optionally includes a fixed member 306 and an arc-shaped plate 303. The fixed member 306 is connected to the first driving member. The arc-shaped plate 303 is relatively fixed to the fixed member 306. The side of the arc-shaped plate 303 facing the second conveyor belt 100 is an arc-shaped protruding surface. Under the action of the first driving member, one end of the arc-shaped plate 303 indirectly presses against the first support roller 301, and the other end indirectly presses against the second support roller 302. The arc-shaped plate 303 presses the first conveyor belt 220 and the second conveyor belt 100 against the first support roller 301 and the second support roller 302, thereby achieving full contact between the first conveyor belt 220 and the second conveyor belt 100. At the same time, the second conveyor belt 100 is guided by the arc-shaped plate 303 during the conveyor belt movement and slides relative to the arc-shaped plate 303. In this embodiment, a crescent-shaped arc-shaped plate 303 is used. In other embodiments, the conveyor belt guide may also be a guide roller that can roll with the second conveyor belt 100, which guides the second conveyor belt 100 by rolling friction while ensuring full contact between the first conveyor belt 220 and the second conveyor belt 100.

[0042] like Figure 1 and Figure 2As shown, the conveyor belt cleaning device optionally further includes a self-cleaning assembly 400, which includes a first mounting frame 401 and a brush roller 402. The brush roller 402 is rotatably mounted on the first mounting frame 401, and the first conveyor belt 220 is also mounted on the brush roller 402. The brush roller 402 cleans the first conveyor belt 220, achieving self-cleaning of the first conveyor belt 220. The first conveyor belt 220 can be reused multiple times, and the first conveyor belt 220 cyclically cleans the second conveyor belt 100. In this embodiment, the surface of the brush roller 402 is provided with a detachable brush sleeve, and the brush material can be selected from sponge or bristles.

[0043] like Figure 1 and Figure 2 As shown, optionally, a brush roller 402 is height-adjustably mounted on the first mounting frame 401. By adjusting the height of the brush roller 402, the tension of the first conveyor belt 220 can be changed, thereby maintaining a reasonable tension on the first conveyor belt 220 and increasing the friction of the brush roller 402 on the first conveyor belt 220. Furthermore, three brush rollers 402 are provided.

[0044] like Figure 1 and Figure 2 As shown, the self-cleaning assembly 400 optionally further includes a detergent sprayer 403, disposed on one side of the first conveyor belt 220. The detergent sprayer 403 sprays detergent onto the first conveyor belt 220, working in conjunction with the brush roller 402 to facilitate cleaning of impurities adhering to the first conveyor belt 220, thereby improving cleaning efficiency and effectiveness. During the cleaning operation, the detergent is continuously sprayed to wet the first conveyor belt 220. When the cleaning operation ceases, the detergent sprayer 403 also ceases operation. In this embodiment, the detergent may be alcohol, and the detergent sprayer 403 is an electric spray gun.

[0045] like Figure 1 and Figure 2 As shown, optionally, the transmission mechanism 210 includes a first reel 211, a second reel 212, and a second drive member 213. The two ends of the first conveyor belt 220 are respectively wound on the first reel 211 and the second reel 212. The second drive member 213 is connected to the second reel 212 to drive the second reel 212 to rotate. Driven by the second drive member 213, one of the first reel 211 and the second reel 212 unwinds and the other reels, thereby achieving the running of the first conveyor belt 220, thereby wiping and cleaning the second conveyor belt 100. In this embodiment, the second drive member 213 can be a motor. The first reel 211 and the second reel 212 can be pneumatic shafts, which can be tightened to fix the reel of the first conveyor belt 220. The first reel 211 and the second reel 212 can also be matched with the reel of the first conveyor belt 220 through a slot.

[0046] like Figure 1 and Figure 2 As shown, the conveyor belt cleaning device optionally further includes a tension adjustment assembly 500, which includes a second mounting frame 501 and a tension adjustment roller 502. The tension adjustment roller 502 is adjustably mounted on the second mounting frame 501, and the first conveyor belt 220 is also mounted on the tension adjustment roller 502. By adjusting the position of the tension adjustment roller 502 on the second mounting frame 501, the tension of the first conveyor belt 220 can be adjusted.

[0047] Optionally, the first conveyor belt 220 includes a PEF film or a dust-free cloth. The PEF film and the dust-free cloth are low-cost, have good cleaning effects, and are both less hard than the second conveyor belt 100, thereby reducing wear on the second conveyor belt 100.

[0048] like Figure 1 and Figure 2 As shown, the conveyor belt cleaning device also includes a control device 600 for realizing the automation of the conveyor belt cleaning device. Specifically, the control device 600 includes a processor, a control panel, and a communication module. The processor can identify the input signal manually input into the control panel and generate an execution signal based on the input signal. The execution signal is sent to the execution units such as the first drive member, the second drive member 213, the tension adjustment component 500, and the detergent spraying member 403 through the communication module, thereby controlling the execution units to perform various actions respectively. The communication mode of the communication module can be wired communication or wireless communication. The control device 600 can also perform timing operations to realize the timing start or stop of each execution unit.
