Technical Field

[0001] The invention relates to the technical field of conveyor chains, in particular to a conveyor chain capable of reducing wear. Background Art

[0002] In the patent application with application announcement number CN109941673B, it includes a plurality of chain links connected in sequence, the chain links include a chain plate group, a sleeve arranged between the chain plate groups, a roller sleeved on the sleeve, and a pin shaft passing through the chain plate group and the sleeve, the chain plate group includes two inner chain plates arranged at intervals and two outer chain plates located outside the inner chain plates and arranged at intervals; sleeve clamping holes are provided at both ends of the inner chain plates, and an inner chain plate clamping sleeve with a notch and for one end of the sleeve to be embedded is embedded in the sleeve clamping hole; pin shaft clamping holes are provided at both ends of the outer chain plates, and an outer chain plate clamping sleeve with a notch and for one end of the pin shaft to be embedded is embedded in the pin shaft clamping hole. The advantages are: due to the sealing design of the chain, the sleeve, roller and pin shaft can be used in a relatively clean lubricating environment, so that they can be used in natural wear and tear, thereby extending their service life. Without being disturbed by external dust or other factors, it ensures good wear resistance, so that the chain lengthening speed will be much slower than similar products under unnatural wear, thereby extending the service life of the chain and achieving a more durable use purpose.

[0003] In the prior art including the above-mentioned patents, in daily use, the conveyor chain is in contact with the gears for a long time, and the roller part will bear most of the friction. The longer it is used, the thinner the roller becomes. Due to the high operating speed during operation, it is impossible to carefully observe the degree of wear of each roller. After long-term use, uneven stress may cause risks such as breakage. Summary of the invention

[0004] The problem to be solved by the present invention is that the conveyor chain is used for a long time, and the roller and gear connection parts are worn out, resulting in stress weakening and fracture, which affects the normal operation of the conveyor chain.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a conveyor chain capable of reducing wear, comprising a conveyor belt, a connecting shaft is movably provided on one side of the conveyor belt, a gear is provided on the top of the connecting shaft, and a wear-resistant structure is provided on the top of the gear; The wear-resistant structure includes a roller, a plurality of square grooves are opened on the top of the roller in a circular array, oil cotton is arranged inside the roller, arc plates are fixed on both sides of the bottom of the inner wall of the square groove, the top of the arc plate is semicircular and has a certain elasticity, and a pressing block is arranged on the top of the arc plate.

[0006] Preferably, the pressing block is matched with the square groove, and the pressing block will squeeze the arc plate after being forced to move downward.

[0007] Preferably, the top of the pressing block is provided with a plurality of liquid outlets in a straight line shape, and the liquid outlets can allow the lubricating liquid in the oil cotton to be discharged outward.

[0008] Preferably, a roller is rotatably provided inside the roller, a coupling is provided inside the roller, and chain plates are provided on the front and back sides of the coupling.

[0009] Preferably, a warning plate is provided on the surface of the roller, the color of the warning plate is red, and wear-resistant blocks are fixedly provided on both sides of the surface of the warning plate.

[0010] Preferably, a bracket is provided at the bottom of the conveyor belt, a conveyor box is provided at the top of the conveyor belt, and the bottom of the conveyor box is matched with the wear-resistant structure.

[0011] Preferably, a shell is fixedly provided on one side of the front and back sides of the conveyor belt, a threaded groove is provided on one side of the shell, a slide rail is provided inside the shell, a movable block is slidably provided on the slide rail, the movable block is fixedly connected to the connecting shaft, a threaded rod is rotatably provided on one side of the movable block, and the threaded rod is adapted to the threaded groove.

[0012] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The conveyor belt is provided with a wear-resistant structure. The wear-resistant structure can reduce the wear between the roller and the gear through the cooperation between the pressing block, the arc plate and the oil cotton. When the roller passes through the gear, the pressure of the gear controls the pressing block to move inward. The pressing block cooperates with the arc plate to form a certain buffering force to prevent the friction force from directly acting on the roller surface. In addition, the extrusion force will also squeeze the pressing block to form a pressing force on the oil cotton. The lubricating oil inside the oil cotton after being pressed will overflow from the liquid outlet on the pressing block to form lubrication, further reducing the friction between the roller and the gear. Through buffering and lubrication, the wear of the roller is greatly delayed, and the roller is prevented from being worn and thinned to cause uneven stress and breakage, which affects the normal use of the conveyor belt, reduces labor maintenance costs and improves work efficiency. (2) The roller is provided with a roller shaft inside, and a warning plate and a wear-resistant block are provided on the surface. When the roller moves and passes through the gear, a certain displacement will occur to prevent a certain position of the roller from being in contact with the gear all the time. The warning plate and the wear-resistant block can further increase the wear resistance of the roller. When the pressing block is worn after long-term use and the wear reaches a certain degree, the gear will contact the wear-resistant block, which can also play a wear-resistant effect. Later, when the wear-resistant block is worn to a certain bottom, the red warning plate will show a bright red color. In this way, during daily work, even if the conveyor chain moves at a fast speed, the user can capture the chain wear warning line with the naked eye. When seeing red, the conveyor belt can be stopped in time for maintenance. In addition, the red warning can also allow the user to quickly find the severely worn parts and locate the worn parts for replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figures 1 to 10 As shown, the present invention provides a conveyor chain capable of reducing wear, comprising a conveyor belt 2, a connecting shaft 8 is movably provided on one side of the conveyor belt 2, a gear 5 is provided on the top of the connecting shaft 8, and a wear-resistant structure 4 is provided on the top of the gear 5; The wear-resistant structure 4 includes a roller 402, the top of which is provided with a plurality of square grooves in a circular array, the interior of the roller 402 is provided with oil cotton 409, arc plates 410 are fixedly provided on both sides of the bottom of the inner wall of the square groove, the top of the arc plate 410 is semicircular and has a certain elasticity, and a pressing block 403 is provided on the top of the arc plate 410.

[0018] The pressing block 403 is matched with the square groove, and the pressing block 403 presses the arc plate 410 after being forced to move downward.

[0019] The top of the pressing block 403 is provided with a plurality of liquid outlets 405 in a straight line shape, and the liquid outlets 405 can discharge the lubricating liquid in the oil cotton 409 to the outside.

[0020] A roller 407 is rotatably provided inside the roller 402 , a coupling 406 is provided inside the roller 407 , and chain plates 401 are provided on the front and back sides of the coupling 406 .

[0021] A warning plate 408 is provided on the surface of the roller 402 . The color of the warning plate 408 is red. Wear-resistant blocks 404 are fixedly provided on both sides of the surface of the warning plate 408 .

[0022] A bracket 3 is provided at the bottom of the conveyor belt 2 , a conveyor box 1 is provided at the top of the conveyor belt 2 , and the bottom of the conveyor box 1 is matched with the wear-resistant structure 4 .

[0023] A shell 7 is fixedly provided on one side of the front and back of the conveyor belt 2, a threaded groove is provided on one side of the shell 7, a slide rail is provided inside the shell 7, a movable block 6 is slidably provided on the slide rail, the movable block 6 is fixedly connected to the connecting shaft 8, a threaded rod 9 is rotatably provided on one side of the movable block 6, and the threaded rod 9 is adapted to the threaded groove.

[0024] The working principle and use process of the present invention are as follows: when the conveyor belt 2 is used normally to control the movement of the conveyor box 1, the tension between the gear 5 and the roller 402 is first adjusted by rotating the threaded rod 9 to adjust it to a suitable tensioning range. The rotating threaded rod 9 can drive the movable block 6 to move along the slide rail in the shell 7. The movable block 6 controls the movement of the gear 5 through the connecting shaft 8. After the gear 5 moves to a suitable position, the conveyor belt 2 can be started for normal transportation operations. When the roller 402 passes through the gear 5 during its operation, the latch teeth on the gear 5 will mesh with the roller 402 and generate a pulling stress and friction force toward one side. The force will preferentially act on the pressing block 403. After receiving the pressure, the pressing block 403 will move toward the inside of the roller 402 and squeeze the arc plate 410. As the pressing block 403 presses, the lubricating oil stored in the oil cotton 409 The liquid will overflow through the liquid outlet 405 to lubricate the surfaces of the gear 5 and the pressing block 403. Since the arc plate 410 has a certain elasticity, after the pressing block 403 is separated from the gear 5, it will return to the initial position and wait for the next press. After a long time, the pressing block 403 will be worn into a concave shape and the friction and pressure of the gear 5 will act on the wear-resistant block 404. The wear-resistant block 404 can also provide a longer period of use for the roller 402, until the wear-resistant block 404 is also severely worn, the bright color of the warning plate 408 will be exposed. When the chain is used, the user can also see at a glance that the roller 402 is severely worn and needs to be replaced in time. In the use environment of a long operating chain, the user can also quickly find the section with the most severe wear and replace it, so as to locate the wear more accurately and quickly.
