Description

[0001] The invention relates to the technical field of sprocket conveyors, in particular to an anti-slip sprocket synchronous conveyor. Background Art

[0002] The sprocket synchronous conveyor is a conveying machine that uses the synchronous transmission of sprockets and chains to pull and carry materials. It ensures that the chain maintains stable synchronous motion during the conveying process through precise control of the sprocket, thereby achieving continuous and smooth conveying of materials.

[0003] In the process of the chain driving the sprocket to rotate, affected by some factors (for example, after the chain is used for a long time, the sprocket will wear, resulting in poor engagement between the chain and the sprocket, or the tension at both ends of the chain is inconsistent, and it becomes loose during use), the chain will fall off the sprocket. The chain is an important component of mechanical transmission, responsible for transmitting power from one place to another. The chain falling off will not only cause the power transmission to be interrupted, making the conveying equipment unable to work normally, but even if the chain does not fall off completely, poor engagement or relaxation will also lead to a decrease in power transmission efficiency, affecting the overall operating efficiency of the equipment, aggravating the wear of the chain and sprocket, shortening their service life, and long-term abnormal wear will also cause damage to other related components.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides an anti-slip sprocket synchronous conveyor, which has the following beneficial effects:

[0019] 1. The chain loosening warning mechanism can maintain the tension of the chain body when the chain body is slightly loose, and trigger the alarm in time when the chain body is too loose. It can not only maintain the tension of the chain in time, but also effectively prevent the chain body from falling off the sprocket body, thereby ensuring the continuity and stability of power transmission, avoiding sudden shutdown of the conveying equipment due to the falling of the chain body, and improving the reliability and stability of the overall production line. It is also convenient for the staff to find and deal with the problem of loose chain body in time, avoiding greater failures and higher maintenance costs caused by the accumulation of problems. At the same time, since the downtime caused by chain body problems is reduced, the utilization rate and production efficiency of the conveying equipment are also improved.

[0020] 2. The jacking plate, lifting block and dial plate can automatically disconnect the power supply connected to the chain body when the chain body falls off or breaks. This can not only prevent the conveying equipment from continuing to run after the chain body falls off or breaks, thereby avoiding further damage to the conveying equipment itself, such as reducing the wear and breakage of gears and bearing components, but also automatically cut off the power supply when the chain body falls off or breaks, which can quickly eliminate the danger caused by mechanical loss of control.

[0021] 3. Through the chain lubrication mechanism, the lubricant can be evenly applied to all parts of the chain body during the operation of the chain body, which can not only reduce the direct contact between the chain body and the sprocket body, thereby reducing the wear rate and extending the service life of the chain body and related parts, but also the lubricant can form a protective film on the surface of the chain body to prevent the chain body from directly contacting the oxygen, moisture and corrosive substances in the air, thereby reducing the corrosion and wear of the chain body.

[0022] 4. Through the setting of the push rod, the fluctuation amplitude of the chain body during operation can be converted into the intermittent opening of the gate valve on the infusion pipe, and the circulation amount of the lubricant can be controlled. This can not only ensure that the chain body is provided with an appropriate amount of lubricant when lubrication is needed, avoiding the problem of insufficient lubrication or excessive lubrication, but also avoid the waste of lubricant, reduce the cost of lubricant use, and reduce lubricant leakage and pollution.

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] An anti-slip sprocket synchronous conveyor of this embodiment, such as Figure 1 - Figure 8As shown, it includes symmetrically arranged side plates 1, and conveying rollers 2 are equidistantly rotatably connected between the side plates 1. Sprocket bodies 6 are fixedly connected at both ends of the conveying rollers 2. Chain bodies 7 are sleeved between the sprocket bodies 6 on the same side. A power switch 5 is provided on the side of the side plate 1 away from the conveying roller 2. A through groove 3 is opened on the side of the side plate 1 away from the conveying roller 2. A chain loosening warning mechanism is provided between the side plate 1 and the chain body 7. The chain loosening warning mechanism is used to trigger an alarm and stop the operation of the chain body 7 when an abnormal situation occurs in the chain body 7.

[0038] In this embodiment, Figure 4 and Figure 6 As shown, the chain loosening warning mechanism includes a lifting plate 401, which is slidably connected in the through groove 3, and a top rod 408 is fixedly connected to the upper end surface of the lifting plate 401, and a tensioning spring 402 is fixedly connected between the lower end surface of the lifting plate 401 and the through groove 3. The initial state of the tensioning spring 402 is a stretched state, and a connecting column 413 is fixedly connected to the side of the side plate 1 on the lower end surface of the lifting plate 401, and a tensioning plate 414 is fixedly connected to the lower end of the connecting column 413. The tensioning plate 414 is attached to the inner wall of the chain body 7. Through the set tensioning spring 402, a downward pressure can be applied to the lifting plate 401, so that the lifting plate 401 pushes the tensioning plate 414 to always fit the chain body 7 through the connecting column 413.

[0039] In this embodiment, Figure 4 As shown, a push plate 403 is rotatably connected to the side wall of the lifting plate 401, and a movable plate 404 is rotatably connected to the side wall of the side plate 1 on the push plate 403 away from the lifting plate 401. The movable plate 404 is horizontally slidably connected to the side wall of the side plate 1. When the lifting plate 401 moves up and down, the push plate 403 can push the movable plate 404 to slide horizontally on the side wall of the side plate 1.

[0040] In this embodiment, Figure 5 As shown, a lever 405 is fixedly connected at the center of the upper end surface of the movable plate 404, a support plate 406 is arranged above the movable plate 404, the support plate 406 is fixedly connected to the side wall of the side plate 1, an alarm 407 is fixedly connected to the upper end surface of the support plate 406, a button 412 is fixedly connected to the lower end surface of the support plate 406, the button 412 and the alarm 407 are electrically connected, the button 412 and the lever 405 are on the same horizontal line, when the movable plate 404 moves horizontally, it will drive the lever 405 to move to the lower end of the support plate 406, so that the lever 405 presses the button 412 to turn on the alarm 407 to work.

[0041] In this embodiment, Figure 4As shown, the side of the movable plate 404 away from the side plate 1 is rotatably connected to a lifting plate 409, and the side of the lifting plate 409 away from the movable plate 404 is rotatably connected to a lifting block 410. The lifting block 410 is vertically slidably connected to the side wall of the side plate 1, and the side of the lifting block 410 away from the movable plate 404 is fixedly connected to a dial plate 411, and the dial plate 411 and the power switch 5 are on the same vertical horizontal line. When the movable plate 404 slides close to the side of the lifting block 410, the lifting block 410 is pushed to rise synchronously through the lifting plate 409, and the dial plate 411 connected to the side wall of the lifting block 410 is driven to toggle the power switch 5 to turn it off.

[0042] In the prior art, the chain is affected by some factors, which may cause the chain to fall off on the sprocket. The chain is an important component of mechanical transmission and is responsible for transmitting power from one place to another. The chain falling off will not only cause the power transmission to be interrupted, making the conveying equipment unable to work normally, but even if the chain is not completely fallen off, poor engagement or looseness will also cause the power transmission efficiency to decrease, affecting the overall operating efficiency of the equipment, aggravating the wear of the chain and sprocket, and shortening their service life. Long-term abnormal wear will also cause damage to other related parts. Compared with the prior art, the chain body 7 can maintain the tension of the chain body 7 when the chain body 7 is slightly loose. Tightening force, and timely triggering the alarm 407 to work when the chain body 7 loosens too much, not only can the chain body 7 be effectively prevented from falling off the sprocket body 6 by timely maintaining the tension of the chain, thereby ensuring the continuity and stability of power transmission, avoiding the sudden shutdown of the conveying equipment due to the falling of the chain body 7, and improving the reliability and stability of the overall production line, but also it is convenient for the staff to promptly discover and deal with the problem of loose chain body 7, avoiding greater failures and higher maintenance costs caused by the accumulation of problems. At the same time, since the downtime caused by the problem of chain body 7 is reduced, the utilization rate and production efficiency of the conveying equipment are also improved.

[0043] In other aspects, the present embodiment also provides a chain lubrication mechanism for applying lubricant to the chain body 7 when the chain body 7 is running, such as Figure 1 , Figure 6 - Figure 8 As shown, the chain lubrication mechanism includes a shunt pipe 801, which passes through and is fixedly connected to the side plate 1, and the end of the shunt pipe 801 away from the side plate 1 is fixedly connected to an infusion tube 802, and the end of the shunt pipe 801 away from the infusion tube 802 is symmetrically fixedly connected to a smear plate 803, and a plurality of leakage holes 804 are opened on the opposite side between the two smear plates 803, and the smear plates 803 are respectively attached to the outer wall and the inner wall of the chain body 7.

[0044] In this embodiment, Figure 7As shown, a gate valve 805 is fixedly connected to the infusion tube 802, and a valve stem 806 is slidably connected to the gate valve 805. By driving the valve stem 806 to slide up and down in the gate valve 805, the lubricant can flow and stop in the infusion tube 802.

[0045] In this embodiment, Figure 7 As shown, the valve stem 806 is fixedly connected to a frame 807 at one end away from the gate valve 805. The frame 807 is sleeved on the gate valve 805 and is located directly above the push rod 408. When the push rod 408 rises, it can push the frame 807 to drive the valve stem 806 to slide out from the inside of the gate valve 805.

[0046] Compared with the prior art, the lubricant can be evenly applied to all parts of the chain body 7 during the operation of the chain body 7, which can not only reduce the direct contact between the chain body 7 and the sprocket body 6, thereby reducing the wear rate and extending the service life of the chain body 7 and related components, but also the lubricant can form a protective film on the surface of the chain body 7 to prevent the chain body 7 from directly contacting the oxygen, moisture and corrosive substances in the air, thereby reducing the corrosion and wear of the chain body 7.

[0047] The working process and principle involved in the overall content of the above embodiment are as follows:

[0048] When the staff turns on the power switch 5 to rotate the conveying rollers 2 between the side plates 1, the sprocket bodies 6 connected to the two ends of the conveying rollers 2 can be used to move the chain body 7 around the sprocket body 6. Since the chain body 7 and the sprocket body 6 are not over-tensioned, the chain body 7 will vibrate slightly during the movement. As the chain body 7 vibrates, the tensioning plate 414 attached to the inner wall of the chain body 7 is pushed to slide upward, and the connecting column 413 connected to the upper end of the tensioning plate 414 pushes the lifting plate 401 in the through groove 3. The chain body 7 rises synchronously, pulling the tensioning spring 402 between the lifting plate 401 and the through slot 3. When the chain body 7 is affected by the shaking and moves away from the tensioning plate 414, the rebound force of the tensioning spring 402 will pull the lifting plate 401 and the connecting column 413, so that the tensioning plate 414 automatically descends and always fits on the chain body 7, maintaining the tension of the chain body 7, and effectively preventing the chain body 7 from falling off the sprocket body 6, thereby ensuring the continuity and stability of power transmission, avoiding the sudden shutdown of the conveying equipment due to the falling of the chain body 7, and improving the reliability and stability of the overall production line;

[0049] When the lifting plate 401 is affected by the chain body 7 and the tension spring 402 and slightly reciprocates up and down in the through groove 3, it will push the top rod 408 connected to the upper end surface to rise synchronously. Since the lower end surface of the frame 807 is attached to the upper end of the top rod 408, when the top rod 408 moves with the lifting plate 401, it will push the frame 807 to rise synchronously, driving the valve stem 806 connected to the top of the frame 807 to slide upward from the inside of the gate valve 805, but it will not slide out of the gate valve 805, so that the lubricant in the infusion tube 802 flows into the shunt tube 801. After the chain 808 is lowered and separated from the frame 807, the frame 807 and the valve stem 806's own gravity will push the valve stem 806 to automatically descend into the gate valve 805, blocking the flow of lubricant. This is repeated, so that the lubricant can intermittently flow from the infusion tube 802 into the shunt tube 801 and then into the smear plate 803. This can not only ensure that the chain body 7 is provided with an appropriate amount of lubricant when lubrication is needed, avoiding the problem of insufficient lubrication or excessive lubrication, but also avoid the waste of lubricant, reduce the cost of lubricant use, and reduce lubricant leakage and pollution.

[0050] After the lubricant enters the smear plate 803, since the smear plates 803 are respectively attached to the outer wall and the inner wall of the chain body 7, during the movement of the chain body 7, it will pass between the two smear plates 803. At this time, the lubricant inside the smear plate 803 will flow into the chain body 7 through the leak hole 804, and the lubricant will be evenly applied to all parts of the chain body 7, which can not only reduce the direct contact between the chain body 7 and the sprocket body 6, thereby reducing the wear rate and extending the service life of the chain body 7 and related parts, but also the lubricant can form a protective film on the surface of the chain body 7 to prevent the chain body 7 from directly contacting with oxygen, moisture and corrosive substances in the air, thereby reducing corrosion and wear of the chain body 7;

[0051] During the movement of the chain body 7 around the sprocket body 6, if the looseness of the chain body 7 is too large, the tensioning spring 402 will be over-contracted, pulling the lifting plate 401 down in the through slot 3, and driving the tensioning plate 414 to press down the chain body 7 through the connecting column 413. While maintaining the tension of the chain body 7, the lifting plate 401 will change the inclination angle of the push plate 403 through the push plate 403 rotatably connected on the side wall, and push the push plate 403 away from the moving plate 404 connected to one side of the lifting plate 401 to slide horizontally on the side wall of the side plate 1 away from the lifting plate 401. During the horizontal movement of the moving plate 404, the upper end surface of the moving plate 404 is connected The lever 405 will move synchronously. At this time, the lever 405 will follow the moving plate 404 to move below the support plate 406, and press the button 412 connected to the lower end surface of the support plate 406. Since the button 412 is electrically connected to the alarm 407, when the button 412 is pressed, the alarm 407 connected to the upper end surface of the support plate 406 will be turned on to work, so that the staff can find and deal with the problem of loose chain body 7 in time, avoiding greater failures and higher maintenance costs caused by the accumulation of problems. At the same time, since the downtime caused by the problem of chain body 7 is reduced, the utilization rate and production efficiency of the conveying equipment are also improved.

[0052] When the chain body 7 falls off from the sprocket body 6 or breaks, the resistance of the tensioning plate 414 disappears. At this time, the tensioning spring 402 pulls the lifting plate 401 down to the lowest point in the through groove 3, and pushes the moving plate 404 to move horizontally away from the lifting plate 401 through the push plate 403 connected between the lifting plate 401 and the moving plate 404. During the horizontal movement of the moving plate 404, the moving plate 404 drives one end of the lifting plate 409 to move synchronously, so that the lifting plate 409 moves from a nearly horizontal state to a vertical state. During the change of the state of the lifting plate 409, the lifting plate 409 pushes the lifting block 410 to move horizontally. The side plate 1 rises synchronously on the side wall. Since the side wall of the lifting block 410 is connected with a dial plate 411, and the dial plate 411 and the power switch 5 are on the same vertical horizontal line, during the rising process of the lifting block 410, the dial plate 411 will be driven to rise synchronously and contact the power switch 5, and the power switch 5 will be turned to disconnect the power connected to the chain body 7. This can not only prevent the conveying equipment from continuing to run after the chain body 7 falls off or breaks, thereby avoiding further damage to the conveying equipment itself, such as reducing the wear and breakage of gears and bearing components, but also when the chain body 7 falls off or breaks, automatically cutting off the power supply can quickly eliminate the danger caused by mechanical loss of control.

Obviously, many modifications and changes can be made according to the content of this specification.
