Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, and in particular to a conveyor with a self-cleaning mechanism. Background Art

[0002] Conveyors are equipment used to continuously transport materials and are widely used in coal, electricity, chemical industry, light industry, food, transportation and other sectors. Conveyors have the characteristics of simple structure, wide range of conveying materials, large conveying capacity, small conveying resistance, and easy automatic control. In various industrial production processes, conveyors can efficiently complete the transportation and delivery of materials, improve production efficiency, reduce labor intensity, and save costs.

[0003] The existing devices have some disadvantages during use. For example, the belt surface of a large belt conveyor is usually exposed, and the inner and outer surfaces of the conveyor belt are easily contaminated with dust, so the conveyor belt surface needs to be cleaned regularly. In the existing cleaning method, the belt surface is usually removed as a whole, and then the outer surface is cleaned with a water gun. This method is time-consuming and labor-intensive, and the efficiency is relatively low. Utility Model Content

[0004] The utility model aims to provide a conveyor with a self-cleaning mechanism to solve the problem that in the existing cleaning method, the belt surface is usually disassembled as a whole and then the outer surface is cleaned by a water gun, which is time-consuming, labor-intensive and relatively inefficient.

[0012] In the above scheme, the reset spring is wound on the limiting slide rod to prevent the reset spring from undergoing large deformation during extension and compression, and the two ends of the reset spring are respectively fixed to the cross plate and the bottom plate to prevent the reset spring from deflecting during use.

[0013] As a preferred embodiment of the above technical solution, the bottom end of the water-absorbing sponge block is in contact with the conveying surface at the top of the conveyor belt.

It absorbs moisture and can clean impurities on the surface of the conveyor belt 12 through friction and adsorption. Water washing can improve the cleaning effect of the conveyor belt 12. The ends of the conveying roller 11 and the cleaning roller 14 are connected to a driving mechanism. An auxiliary cleaning mechanism is provided on one side of the upper end surface of the mounting frame 10. During specific use, the conveyor belt 12 is driven by the two conveying rollers 11 to perform transmission operations, and the sponge strip 15 is driven to rotate by the cleaning roller 14 to clean the conveying surface of the conveyor belt 12. The conveying roller 11 and the cleaning roller 14 are driven to rotate synchronously by the driving mechanism, and the conveying surface of the conveyor belt 12 is further cleaned by the auxiliary cleaning mechanism.

[0028] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, the driving mechanism includes an active synchronous wheel 20 fixedly sleeved on the end of one of the conveying rollers 11 and a driven synchronous wheel 21 fixedly sleeved on the end of the cleaning roller 14, and a synchronous belt 22 is sleeved on the outer side of the active synchronous wheel 20 and the driven synchronous wheel 21. A driving motor 23 is fixedly connected to the end of one of the conveying rollers 11, and an L-shaped plate 24 is fixedly installed on the side wall of the mounting frame 10. The driving motor 23 is fixedly installed on the L-shaped plate 24. The driving motor 23 is fixed by the L-shaped plate 24, so that the driving motor 23 can be used stably. During specific use, the conveying roller 11 is driven to rotate by the driving motor 23, and the active synchronous wheel 20 and the driven synchronous wheel 21 are driven to rotate synchronously by the synchronous belt 22, so that the conveying roller 11 and the cleaning roller 14 can rotate at the same time. This structure can drive the conveying roller 11 and the cleaning roller 14 by one driving member, which saves the use cost to a certain extent.

[0029] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the auxiliary cleaning mechanism includes a base plate 30 that is laterally symmetrically fixedly installed on the mounting frame 10, and the upper end surfaces of the base plate 30 are fixedly connected to two limit sliding bars 31, and a cross plate 32 is slidably connected to the outer walls of the two laterally symmetrically arranged limit sliding bars 31, and a return spring 33 is arranged between the cross plate 32 and the base plate 30, and the return spring 33 is wound around the outer wall of the limit sliding bar 31, and the top end of the return spring 33 is fixedly connected to the lower end surface of the cross plate 32, and the bottom end of the return spring 33 is fixedly connected to the upper end surface of the base plate 30. The return spring 33 is wound around the limit sliding bar 31 to prevent the return spring 33 from undergoing large deformation during extension and compression, and the two ends of the return spring 33 are respectively fixed to the cross plate 32 and the base plate 30 to prevent the return spring 33 from deflecting during use, and the top ends of the two laterally symmetrically arranged limit sliding bars 31 are fixedly installed with the limit baffle by bolts 34. The movement range of the cross plate 32 is limited by the limit baffle 34. The lower end surface of the cross plate 32 is fixedly connected with a water-absorbing sponge block 35. The bottom end of the water-absorbing sponge block 35 contacts the conveying surface at the top of the conveyor belt 12. The water stains on the conveyor belt 12 are absorbed by the water-absorbing sponge block 35 to ensure the dryness of the surface of the conveyor belt 12. During specific use, the conveying surface of the conveyor belt 12 is cleaned by the water-absorbing sponge block 35. The downward pulling force of the reset spring 33 is set to make the water-absorbing sponge block 35 on the cross plate 32 always contact the conveying surface of the conveyor belt 12, and the elastic function of the reset spring 33 can make the water-absorbing sponge block 35 not affect the normal transmission of the conveyor belt 12 during the contact with the conveyor belt 12. When the water-absorbing sponge block 35 encounters resistance, the reset spring 33 stretches, thereby driving the cross plate 32 to rise.

[0030] Working principle: First, the two conveying rollers 11 are used to drive the conveying belt 12 to perform transmission operation, and the cleaning roller 14 is used to drive the sponge strip 15 to rotate, so as to clean the conveying surface of the conveying belt 12. When in use, the driving motor 23 drives the conveying roller 11 to rotate, and the synchronous belt 22 is used to drive the active synchronous wheel 20 and the driven synchronous wheel 21 to rotate synchronously, so that the conveying roller 11 and the cleaning roller 14 can rotate at the same time. This structure can drive the conveying roller 11 and the cleaning roller 14 through a driving member. The water-absorbing sponge block 35 is driven in a row, which saves the use cost to a certain extent. The conveying surface of the conveyor belt 12 is cleaned by the water-absorbing sponge block 35. The downward pulling force of the reset spring 33 is set to make the water-absorbing sponge block 35 on the cross plate 32 always contact with the conveying surface of the conveyor belt 12, and the elastic function of the reset spring 33 can make the water-absorbing sponge block 35 not affect the normal transmission of the conveyor belt 12 during the process of contacting the conveyor belt 12. When the water-absorbing sponge block 35 encounters resistance, the reset spring 33 stretches, thereby driving the cross plate 32 to rise.
