Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, and more specifically to a chain used for conveyors. Background Art

[0002] Conveyor chain is an important component used in conveyor systems and is usually composed of a series of interconnected links. These links are connected together by pins to form a closed loop structure.

[0003] As time goes by and the frequency of use increases, the pitch of the conveyor chain may increase due to the microscopic stretching of the metal, which may be caused by the wear of chain components (such as pins and links). The stretched chain will become loose, and the chain is prone to jumping, falling off or slipping due to relaxation, thus affecting the transmission efficiency and stability; during the movement of the chain, friction will occur between the links and pins, and long-term friction will cause wear on the surface of the chain and sprocket. In harsh working environments, the chain is easily eroded by water, dust, chemicals, etc., causing corrosion and oxidation on the chain surface, affecting the service life. Utility Model Content

[0021] Reference Figure 1-Figure 5 The utility model provides a chain for a conveyor, including a chain body 2, characterized in that: the chain body 2 is installed on the conveyor body 1, the chain body 2 includes an outer chain plate 201, a pin 202, an inner chain plate 203, a roller 204, and a sleeve 205, the outer chain plate 201 and the pin 202 as well as the inner chain plate 203 and the sleeve 205 are all interference fits, the roller 204 and the sleeve 205 as well as the sleeve 205 and the pin 202 are all clearance fits, a lubrication component 3 is installed on the right side of the top of the conveyor body 1, a collection component 4 is installed on the right side of the bottom of the conveyor body 1, and a tension adjustment component 5 is installed in the middle of the bottom of the conveyor body 1.

[0022] In the embodiment of the present application, the conveyor body 1 is a common prior art, which will not be described in detail in the present application. The chain body 2 passes through the inner wall of the positioning frame 504 and the roller 505. After long-term use, the chain body 2 will become loose. By rotating the handle block 503, the threaded column 502 can be driven to rotate. Under the action of the threaded engagement between the third fixing frame 501 and the threaded column 502, the positioning frame 504 moves downward, and the roller 505 generates a downward pulling force on the surface of the inner side of the chain body 2, so that the chain body 2 can be kept in an appropriately tensioned state, preventing the chain body 2 from jumping, falling off or slipping due to relaxation, thereby improving the stability and reliability of the transmission of the chain body 2.

[0023] The interior of the charging bottle 302 is filled with lubricating liquid. Due to the effect of the rubber valve inside the liquid outlet 303, the lubricating liquid will not flow out under the action of gravity. When the chain body 2 needs to be lubricated, the charging bottle 302 is squeezed. Under the action of pressure, the lubricating liquid passes through the rubber valve and drips from the bottom of the liquid outlet 303 onto the surface of the chain body 2, thereby achieving rapid lubrication of the chain body 2. During the transmission process of the chain body 2, the cleaning brush 403 can clean the excess lubricating liquid at the bottom of the chain body 2, and the excess lubricating liquid flows along the cleaning brush 403 into the interior of the collecting frame 402 for collection, thereby preventing excess lubricating liquid from dripping into other areas and causing pollution.

[0024] In a preferred embodiment, the lubrication assembly 3 includes a first fixed frame 301, a charging bottle 302 is installed on the top of the first fixed frame 301, a liquid outlet 303 is installed on the bottom of the charging bottle 302, a rubber valve is installed on the inner side of the liquid outlet 303, and the interior of the charging bottle 302 is filled with lubricating liquid. The rubber valve prevents the lubricating liquid from flowing out under the action of gravity.

[0025] In a preferred embodiment, the collecting assembly 4 includes a second fixing frame 401, a collecting frame 402 is fixedly connected to the back of the second fixing frame 401, a cleaning brush 403 is fixedly connected to the middle of the inner side of the collecting frame 402, and the cleaning brush 403 can evenly spread the lubricating liquid and clean up the excess lubricating liquid.

[0026] In a preferred embodiment, the tensioning adjustment assembly 5 includes a third fixed frame 501, the top of the third fixed frame 501 is threadedly sleeved with a threaded column 502, the bottom of the threaded column 502 is fixedly connected to a handle block 503, the top of the threaded column 502 is movably connected to a positioning frame 504, the top of the inner side of the positioning frame 504 is movably sleeved with a roller 505, and the chain body 2 passes through the inner wall of the positioning frame 504 and the roller 505.

[0027] In a preferred embodiment, positioning rods 506 are fixedly connected to both sides of the bottom of the positioning frame 504, and the bottom of the positioning rods 506 is movably sleeved with a positioning tube 507, and the bottom of the positioning tube 507 is fixedly connected to the surface of the third fixed frame 501. Through the cooperation of the positioning rods 506 and the positioning tube 507, the positioning frame 504 is fixed to prevent the positioning frame 504 from rotating.

[0028] In a preferred embodiment, the collection frame 402 and the chain body 2 are located in a vertical direction at the same time, the bottom of the cleaning brush 403 contacts the surface of the bottom of the chain body 2, and the cleaning brush 403 is in an inclined state, which is convenient for evenly applying the lubricating liquid and for diverting excess lubricating liquid.

[0029] Working principle of the utility model: the conveyor body 1 is a common prior art and will not be described in detail in this application. The chain body 2 passes through the inner wall of the positioning frame 504 and the roller 505. After long-term use, the chain body 2 will become loose. By rotating the handle block 503, the threaded column 502 can be driven to rotate. Under the action of the threaded engagement between the third fixing frame 501 and the threaded column 502, the positioning frame 504 moves downward, and the roller 505 generates a downward pulling force on the surface of the inner side of the chain body 2, so that the chain body 2 can be kept in an appropriately tensioned state, preventing the chain body 2 from jumping, falling off or slipping due to relaxation, thereby improving the stability and reliability of the transmission of the chain body 2.

[0030] The interior of the charging bottle 302 is filled with lubricating liquid. Due to the effect of the rubber valve inside the liquid outlet 303, the lubricating liquid will not flow out under the action of gravity. When the chain body 2 needs to be lubricated, the charging bottle 302 is squeezed. Under the action of pressure, the lubricating liquid passes through the rubber valve and drips from the bottom of the liquid outlet 303 onto the surface of the chain body 2, thereby achieving rapid lubrication of the chain body 2. During the transmission process of the chain body 2, the cleaning brush 403 can clean the excess lubricating liquid at the bottom of the chain body 2, and the excess lubricating liquid flows along the cleaning brush 403 into the interior of the collecting frame 402 for collection, thereby preventing excess lubricating liquid from dripping into other areas and causing pollution.
