Description

Technical Field

[0001] The utility model relates to the technical field of double - layer conveying devices, and particularly relates to a double - layer conveying device. Background Technique

[0002] The double - layer conveying device is an efficient material conveying equipment, and its structure consists of upper and lower layers of conveying chains. Articles usually move on the upper - layer chain, while the lower - layer chain plays a role in support and transmission.

[0003] The double - layer conveying devices in the prior art do not have the function of cleaning the conveyor belt.

During the reciprocating movement of the two sliding frames 2, the two cleaning cotton 6 on the two mounting plates 5 can respectively wipe the bottom surfaces of the two conveyor belts, so as to clean the surfaces of the two conveyor belts.

[0044] The double-layer conveying device further includes a driving structure arranged on the double-layer conveyor 1. The driving structure includes: a rotating shaft 71 fixed on one of the roller shafts of the double-layer conveyor 1; an eccentric wheel 72 fixedly sleeved on the rotating shaft 71, and the eccentric wheel 72 is eccentrically arranged with respect to the rotating shaft 71; a shaft rod 73 fixed at the edge position of the eccentric wheel 72; a sleeve 74 rotatably sleeved on the shaft rod 73; a pulling rope 75, one end of which is connected to the sleeve 74, and the other end is fixedly connected to one of the guiding blocks 3.

[0046] The working principle of the present utility model: <> <>

[0047] The double-layer conveying device proposed by the present utility model has the function of cleaning the conveyor belt. When the double-layer conveyor 1 operates, the roller shaft on the double-layer conveyor 1 can drive the rotating shaft 71 to rotate. When the rotating shaft 71 rotates, it drives the eccentric wheel 72 to rotate. The shaft rod 73 and the sleeve 74 on the eccentric wheel 72 will also rotate around the center of the eccentric wheel 72. The sleeve 74 will drive the corresponding guide block 3 to move through the pull rope 75. At the same time, with the elastic force of the spring, the guide block 3 connected to the pull rope 75 makes a reciprocating movement. The reciprocating guide block 3 can drive another guide block 3 to move through the vertical plate, which makes the two sliding frames 2 make a reciprocating movement. During the reciprocating movement of the two sliding frames 2, the two cleaning cottons 6 on the two mounting plates 5 can respectively wipe the bottom surfaces of the two conveyor belts, thereby playing a role in cleaning the surfaces of the two conveyor belts. It is worth noting that the sleeve 74 is rotatably installed on the shaft rod 73, and this design can prevent the pull rope 75 from being wound around the sleeve 74; <> <>

[0048] The mounting plate 5 is detachably arranged on the sliding frame 2, which facilitates the staff to remove the mounting plate 5 and clean the cleaning cotton 6 thereon. Specifically, when disassembling the mounting plate 5, the staff first pulls down the movable block 83. When the movable block 83 moves downward, it can drive the two push blocks 85 to move downward. When the two push blocks 85 move downward, the two inclined surfaces on the two push blocks 85 no longer squeeze the two connecting rods 87, releasing the restriction of the two push blocks 85. The two pressing rods 86 can approach each other under the action of the two tension springs 88, which causes the two pressing rods 86 to be separated from the sliding frame 2, releasing the pressing effect of the two pressing rods 86. The mounting plate 5 can be detached from the sliding frame 2, realizing the rapid disassembly of the mounting plate 5 with convenient operation.

[0049] The above has described in detail an embodiment of the present invention, but the described content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
