Description

Technical Field

[0002] Belt conveyors are often used to transport small equipment or parts, and there are multiple assembly or testing stations on the outside of the belt conveyor to assemble and test small equipment or parts.

[0003] During the material conveying process of the rubber belt of the belt conveyor, the lubricating grease, dust and impurities on the surface of the material, as well as the hair scraps dropped by the staff during assembly or inspection operations, will adhere to the rubber belt. Over time, the impurities on the surface of the rubber belt will increase and become difficult to clean. The more impurities there are, the greater the impact on the belt conveyor, and the impurities will affect the normal service life of the conveyor belt.

[0004] The cleaning structure of the belt of the belt conveyor in the prior art is to wipe and clean, or to use a knocking structure to knock the materials adhering to the surface of the belt to make them fall off.

[0036] A negative pressure suction unit is used to suck and clean impurities adhered to the surface of the transmission belt 1, and the negative pressure suction unit is also located inside the sleeve frame 2;

[0037] The static electricity removal unit is used to attenuate the static electricity force on the surface of the transmission belt 1 , and the static electricity removal unit is located outside the sleeve frame 2 .

[0038] Preferably, the brushing unit includes a brushing column 6 located at the bottom of each rotating drum 4, and the transmission belt 1 is clamped between the rotating drum 4 and the brushing column 6 which are distributed downwardly. A sliding rod 5 is fixedly inserted inside each brushing column 6.

The outside of the frame 2 is provided with a transmission component for driving several brushing columns 6, and a pushing component for moving the brushing columns 6. When the rotating drum 4 and the brushing column 6 are installed, they are squeezed and installed on the transmission belt 1, that is, the bristles on the surface of the brushing column 6 will exert a certain pressure on the surface of the transmission belt 1.

[0039] Preferably, the transmission component includes a rotating sleeve 7 axially slidably mounted on both ends of each sliding rod 5, and the rotating sleeve 7 is rotatably mounted inside the sleeve frame 2, the outer surfaces of several rotating sleeves 7 located on the same side are fixedly mounted with synchronous gears, and a synchronous belt is arranged for transmission between the several synchronous gears, wherein each rotating sleeve 7 on one side is fixedly mounted with a turntable 8 on an end surface away from the sleeve frame 2, the outer surface of the first or last turntable 8 located on the same side is fixedly mounted with a gear ring 14, and a driving gear 15 is meshed with the outside of the gear ring 14, an electric motor 16 is also fixedly mounted on the outside of the sleeve frame 2, and the output end of the electric motor 16 is fixedly assembled with the driving gear 15, the number of rotating sleeves 7 is three, and the outer diameter of the synchronous gear assembled on the rotating sleeve 7 located in the middle is larger than the outer diameters of the other two synchronous gears.

Since the connecting block 10 is restricted by the protective cover shell 13, the connecting block 10 will cause the slide rod 5 to perform axial displacement.

[0041] Working principle: The transmission belt 1 is inserted between several optical axes 3 and the rotating drum 4 in a wavy manner, and then the transmission belt 1 is clamped by the cleaning column 6 and the rotating drum 4, which can increase the closeness of the contact between the bristles on the surface of the cleaning column 6 and the transmission belt 1, and the texture on the surface of the transmission belt 1 can be exposed to a greater extent by the wavy expansion. When the cleaning column 6 is cleaning, it can have a better cleaning effect on the impurities and stains sticking to the surface of the transmission belt 1;

[0043] In the present solution, since the connecting block 10 is restricted in axial sliding by the protective cover shell 13, and the connecting block 10 is rotatably mounted on the end of the slide rod 5, when the rotating sleeve 7 rotates with the turntable 8, the arc-edged triangular protrusion 9 can push the connecting block 10 through the top column 11, and at the same time, under the action of the first spring 12, the reciprocating movement of the slide rod 5 is realized. During the reciprocating movement of the slide rod 5, it can simultaneously carry the cleaning column 6 for axial reciprocating displacement, that is, the cleaning column 6 can perform axial reciprocating displacement in a rotating state, thereby further improving the cleaning operation on the surface of the transmission belt 1.

[0044] Example 2: Please refer to Figure 7 , Figure 8 , Fig.10 and Fig.11 This embodiment is a further explanation of the first embodiment. Preferably, the negative pressure suction unit includes a suction frame 17 fixedly mounted inside the sleeve frame 2.

[0047] In this embodiment: after the negative pressure suction pump is started, the inside of the suction frame 17 is subjected to negative pressure treatment.

The sucked fiber impurities will adhere to the surface of the dust-proof mesh cylinder 27. Since the dust-proof mesh cylinder 27 can rotate under the action of the motor 16 and the first rotating column 19, and the fiber impurities accumulated on the surface of the dust-proof mesh cylinder 27 can be accumulated in the convergence groove during the rotation process, thereby ensuring the air permeability of the dust-proof mesh cylinder 27;

[0048] Moreover, during the rotation process, the first rotating column 19 can also rotate synchronously with the blade conveying screw 23, and the blade conveying screw 23 can deliver the fiber impurities accumulated in the convergence groove out of the suction frame 17.

Under the action of the first one-way valve and the second one-way valve, the reciprocating movement of the piston disc 30 can convey the static-eliminating agent through the sealing cylinder 29 toward the direction of the atomizing nozzle 37, and spray the static-eliminating agent on the surface of the cleaned transmission belt 1 through the atomizing nozzle 37. The static-eliminating agent can attenuate or even eliminate the static-eliminating force on the surface of the transmission belt 1, thereby effectively preventing the transmission belt 1 from being easily adsorbed by the static-eliminating force after being completely cleaned.
