Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and in particular to a lifting and transporting device for bottled water production. Background Technology

[0002] The production process of bottled water involves multiple steps, from the selection of water source to the packaging and distribution of the final product. These steps mainly include water source selection, water quality testing, water treatment, filling, packaging, and storage and distribution. In the above process, lifting and transportation devices are used in filling, packaging, and storage and distribution. For example, after filling, the bottles are moved from one workstation to another (such as from the filling line to the capping line), and after being boxed, the bottled water is moved from the production line to the warehouse.

[0003] Currently, the lifting and conveying devices used in bottled water production include chain conveyors. Chain conveyors rely on chain transmission to transport bottled water. To ensure stable power transmission and extend the service life of the chain conveyor, a suitable amount of lubricating oil is applied to the chain periodically to reduce friction and wear. During the transportation of bottled water, as the weight of the transported material increases, the load on the chain also increases, leading to increased wear between the chain and sprockets. This necessitates applying more lubricating oil to both the chain and sprockets to ensure lubrication. However, existing methods use oil drippers to apply oil in a timed and quantitative manner. If the initial oil application is too large, it will lead to waste of lubricating oil; conversely, it will cause accelerated wear between the sprockets and chain, thus affecting their service life.

[0038] The third plate is fixed to the transmission cylinder and has circumferentially distributed limiting holes, and the limiting rod is limited to the limiting holes.

[0039] Furthermore, it is particularly preferred that it also includes:

[0040] A counting component, mounted on the gearbox, is used to detect the number of rotations of the conveyor belt. The counting component includes:

[0041] A gear component is rotatably connected to the gearbox, and a reset rod is fixedly connected to the gear component. The reset rod is in a pressing fit with the Geneva wheel.

[0051] The beneficial effects of the present invention are as follows: The present invention detects the weight of bottled water on the conveyor belt by generating relative movement between the transmission cylinder and the first plate, and then controls the amount of lubricating oil applied to the chain by the sprocket, so as to ensure lubrication between the chain and the sprocket.

[0052] This invention adjusts the rotational speed of the truncated cone wheel by changing the transmission ratio between the sliding rod and the truncated cone wheel. This results in the sliding rod moving a greater distance as the weight of bottled water on the conveyor belt increases, thus increasing the rotational speed of the truncated cone wheel. Consequently, the amount of lubricating oil applied to the chain is increased, reducing wear between the chain and the sprocket.

[0053] This invention limits the rotating cylinder with a limiting block, causing it to rotate intermittently. At the same time, when the rotating cylinder rotates, it is made to rotate rapidly under the action of a third elastic element, thereby driving the sealing element to quickly release the blockage at the connection between the oil pipe and the fixed shell, so that the sprocket can quickly apply lubricating oil to the chain.

[0054] This invention uses a limiting rod and a third plate to make the first plate and the transmission cylinder rigidly connected, thereby enabling the transmission cylinder to rotate stably, reducing the speed fluctuation of the transmission cylinder and reducing wear between parts.

[0055] This invention controls the amount of oil applied to the sprocket by the number of rotations of the gear components, so that the entire chain on the conveyor belt is covered with lubricating oil, ensuring that the lubricating oil fully contacts the sprocket and the chain, thus guaranteeing lubrication between them.

Detailed Implementation

[0072] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0073] Research has found that current chain maintenance uses oilers, which apply lubricating oil to the chain in a timed and metered manner. However, during the operation of a chain conveyor, as the amount of material on the chain increases, the friction between the chain and sprockets increases, leading to increased wear on both. Therefore, more lubricating oil needs to be applied between the chain and sprockets. However, the flow rate of existing oilers cannot be adjusted after the initial setting, which further increases the friction between the chain and sprockets, resulting in increased wear on both.

[0074] A lifting and conveying device for bottled water production, such as Figures 1-5 As shown, it includes: a support frame 1, on which a conveyor belt 2 is mounted, and a drive motor 3 is mounted; a spline rod 4, fixedly connected to the output shaft of the drive motor 3, and slidably connected to a first plate 5; a transmission cylinder 6, disposed on the first plate 5, with a first elastic element disposed between the two; a sprocket 7, fixedly connected to the transmission cylinder 6, having an oil storage chamber inside, and having circumferentially distributed oil nozzles all communicating with the oil storage chamber inside, the sprocket 7 being drive-connected to the conveyor belt 2; an oil tank 8, mounted on the support frame 1, with a fixed shell 10 rotatably connected to the sprocket 7, the fixed shell 10 communicating with the oil storage chamber of the sprocket 7, and an oil delivery pipe 9 communicating between the fixed shell 10 and the oil tank 8; and an extrusion assembly, disposed inside the transmission cylinder 6, used to detect the state of the transmission cylinder 6.

[0075] The above scheme provides a method for detecting the amount of material on the conveyor belt 2. The resistance generated by the amount of material, combined with the relative rotation of the spline rod 4 and the transmission cylinder 6, controls the amount of oil dripping. The first elastic element is a torsion spring, and the first plate 5 drives the transmission cylinder 6 to rotate via the first elastic element, thus creating a flexible connection between the sprocket 7 and the output shaft of the drive motor 3. The oil spray nozzle on the sprocket 7 is located between two adjacent teeth, ensuring that oiling is applied to the contact area between the sprocket and the chain. The oil tank 8 stores lubricating oil and is equipped with an oil pump. This scheme allows for setting the number of sprockets 7 according to actual conditions to ensure stable power transmission during material conveying; this paper uses one as an example.

[0076] Working principle: When conveying bottled water, the drive motor 3 is turned on. The output shaft of the drive motor 3 drives the spline rod 4 to rotate. The spline rod 4 drives the first plate 5 to rotate. At the same time, the first plate 5 drives the transmission cylinder 6 to rotate through the first elastic element. The transmission cylinder 6 drives the sprocket 7 to rotate. The sprocket 7 drives the conveyor belt 2 on it to rotate, thus starting the conveying of bottled water.

[0077] When the conveyor belt 2 starts conveying bottled water, the resistance on the sprocket 7 gradually increases, causing relative movement between the transmission cylinder 6 and the first plate 5. This allows for real-time monitoring of the weight of the bottled water on the conveyor belt 2. After relative movement occurs between the transmission cylinder 6 and the first plate 5, the load on the sprocket is detected by the extrusion assembly to determine the amount of oil to be injected into the sprocket. When the sprocket is being oiled, the oil tank 8 starts working, pumping the lubricating oil inside through the oil pipe 9 into the fixed housing 10. Subsequently, the lubricating oil enters the oil storage chamber of the sprocket 7 and is sprayed through the oil spray hole to the contact position between the sprocket and the chain, thus completing the oiling process.

[0078] Furthermore, such as Figures 4-6 As shown, the extrusion assembly includes: an extrusion cylinder 21, disposed within the transmission cylinder 6, with a support rod 22 fixedly connected to the extrusion cylinder 21, and the support rod 22 slidably connected to the spline rod 4; a limiting ball 23, fixedly connected to the extrusion cylinder 21, with a threaded groove provided within the transmission cylinder 6, the number of which shown in the figure is three, and the number of limiting balls 23 is also three, with the limiting balls 23 extruding into the threaded groove; a sliding rod 24, slidably connected to the support frame 1, and the sliding rod 24 extruding into the extrusion cylinder 21; and a speed detection assembly, disposed on the support frame 1, used to detect the moving speed of the conveyor belt 2.

[0079] The above solution provides a method for identifying the amount of material and generating corresponding resistance; the spline rod 4 forms a spline-type hard connection with the extrusion cylinder 21 through the support rod 22, thereby ensuring that the rotation speed of the extrusion cylinder 21 and the spline rod 4 are consistent; an arc-shaped surface is provided on one side of the extrusion cylinder 21, while an inclined surface is provided on the side of the sliding rod 24 near the extrusion cylinder 21; the length of the internal thread groove of the extrusion cylinder 21 in the horizontal direction is equal to the diameter of the sliding rod 24, thus ensuring that during the process of the extrusion cylinder 21 sliding along the thread groove of the transmission cylinder 6, the arc-shaped surface of the extrusion cylinder 21 is always in contact with the inclined surface of the sliding rod 24.

[0080] Working principle: When the sprocket 7 drives the chain on the conveyor belt 2 to rotate, the sprocket 7 generates a speed difference with the spline rod 4 through the transmission cylinder 6. As the amount of material on the conveyor belt 2 increases, the relative rotation angle between the transmission cylinder 6 and the spline rod 4 becomes larger, which in turn causes the transmission cylinder 6 to rotate relative to the extrusion cylinder 21. The number of support rods 22 in this invention is four, so as to ensure the stability of the spline rod 4 driving the extrusion cylinder 21.

[0081] During the rotation of the extrusion cylinder 21, the extrusion cylinder 21 drives the limiting ball 23 to rotate. When the transmission cylinder 6 and the extrusion cylinder 21 rotate relative to each other, the limiting ball 23 and the extrusion cylinder 21 also rotate relative to each other, causing the limiting ball 23 to slide along the threaded groove inside the extrusion cylinder 21. In turn, the limiting ball 23 drives the extrusion cylinder 21 to slide through the support rod 22, thus causing the extrusion cylinder 21 to slide out of the transmission cylinder 6.

[0082] As the extrusion cylinder 21 slides outward toward the transmission cylinder 6, the extrusion cylinder 21 presses against the sliding rod 24, thereby causing the sliding rod 24 to move to the left.

[0083] Furthermore, such as Figure 4 , Figure 7 and Figure 8 As shown, the speed detection component includes: a transmission rod 31, rotatably connected to the support frame 1 and splinedly connected to the sliding rod 24; a detection wheel 32, rotatably connected to the support frame 1 and in contact with the conveyor belt 2, with a rubber layer on the outer side of the detection wheel 32 to increase its friction. During the movement of the conveyor belt 2, the friction between the conveyor belt 2 and the detection wheel 32 drives the detection wheel 32 to rotate. The transmission rod 31 is connected to the detection wheel 32 via a first transmission component. Specifically, the first transmission component in this invention is a straight rod, a set of pulley belts, and a set of bevel gears. The detection wheel 32 is driven by the pulley belt, and the straight rod and the transmission rod 31 are connected by bevel gears. The first transmission component is not specifically as described above and can be modified according to actual conditions, as long as the power of the detection wheel 32 is transmitted to the transmission rod 31; and a transmission deceleration component, set on the support frame 1, used to reduce the output speed of the detection wheel 32.

[0084] Furthermore, such as Figure 4 , Figure 7 and Figure 8 As shown, the transmission reduction assembly includes: a frustum wheel 41, rotatably connected to the support frame 1 and frictionally engaged with the sliding rod 24. The diameter of the frustum wheel 41 on the side closer to the detection wheel 32 is smaller than the diameter on the side farther from the detection wheel 32. By changing the contact position between the sliding rod 24 and the frustum wheel 41, the transmission ratio between them is changed; a reduction gearbox 42, mounted on the support frame 1. The input shaft of the reduction gearbox 42 is connected to the frustum wheel 41 via a second transmission component. The reduction gearbox 42 is an existing device, and its internal structure is not described here. The second transmission component consists of a pulley belt, a straight rod, and a bevel gear set. The frustum wheel 41 drives the straight rod to rotate through the bevel gear set, and the straight rod drives the input shaft of the reduction gearbox 42 to rotate through the pulley belt. The second transmission component has the same function as the first transmission component, which is to transmit power. The structure shown in this invention is only an example and can be modified according to specific circumstances; and a sealing assembly, set on the reduction gearbox 42, used to seal the connection between the oil pipe 9 and the fixed shell 10.

[0085] Working principle: During the movement of the conveyor belt 2, the conveyor belt 2 drives the detection wheel 32 to rotate through friction. The detection wheel 32 drives the transmission rod 31 to rotate through the first transmission component. The transmission rod 31 drives the sliding rod 24 to rotate. The sliding rod 24 drives the frustum wheel 41 to rotate. The frustum wheel 41 drives the input shaft of the reduction gearbox 42 to rotate. The output shaft of the reduction gearbox 42 rotates slowly (that is, the speed of the output shaft of the reduction gearbox 42 is much smaller than the speed of the input shaft of the reduction gearbox 42).

[0086] When the sliding rod 24 moves to the left, the transmission ratio between the sliding rod 24 and the frustum wheel 41 increases, thereby increasing the rotational speed of the frustum wheel 41. As the weight of the bottled water on the conveyor belt 2 increases, the sliding rod 24 moves further to the left, making the rotational speed of the frustum wheel 41 greater, which in turn increases the amount of lubricating oil applied to the chain.

[0087] During the rotation of the output shaft of the gearbox 42, the gearbox 42 releases the blockage at the connection between the oil supply pipe 9 and the fixed housing 10 through the sealing assembly, allowing the lubricating oil to enter the fixed housing 10 along the oil supply pipe 9, thus completing the oiling work.

[0088] Furthermore, such as Figures 9-11 and Figure 14As shown, the sealing assembly includes: a fixed rod 51, rotatably connected to the gearbox 42 and rotatably connected to the transmission cylinder 6; a Geneva wheel 52, fixedly connected to the fixed rod 51, the Geneva wheel 52 is an existing structure, and its single rotation angle can be set according to specific circumstances. In this invention, the single rotation angle of the Geneva wheel 52 is 60°; a sealing element 53, fixedly connected to the fixed rod 51 and slidably connected to the fixed shell 10 and the sprocket 7, the sealing element 53 seals the connection between the oil pipe 9 and the fixed shell 10, the sealing element 53 consists of a ring, a straight rod and a sealing block, wherein the ring, the sprocket 7 and the fixed shell 10 form a closed cavity, the cavity is used to store lubricating oil, and the sealing block is used to seal the connection between the oil pipe 9 and the fixed shell 10, thereby controlling the flow of lubricating oil; and a trigger assembly, set on the gearbox 42, used to control the movement of the Geneva wheel 52.

[0089] Working principle: After the output shaft of the gearbox 42 starts to rotate, the output shaft of the gearbox 42 controls the Geneva wheel 52 to rotate through the trigger component. The Geneva wheel 52 drives the fixed rod 51 to rotate, and the fixed rod 51 drives the sealing member 53 to rotate. The sealing member 53 releases the blockage at the connection between the oil supply pipe 9 and the fixed housing 10, so that the lubricating oil is discharged from the oil injection hole of the sprocket 7.

[0090] Furthermore, such as Figure 9 and Figure 10 and Figure 13 As shown, the triggering assembly includes: a fixed cylinder 61, fixedly connected to the reduction gearbox 42, with several limiting blocks 62 arranged inside the fixed cylinder 61 via a second elastic element, which is a spring. In this invention, three limiting blocks 62 are evenly distributed circumferentially, and each limiting block 62 has an inclined surface; a rotating cylinder 63, rotatably connected to the output shaft of the reduction gearbox 42, with a third elastic element, which is a tension spring, fixed between them; three protrusions evenly distributed circumferentially on the outer side of the rotating cylinder 63, which press against the adjacent limiting blocks 62. When the rotating cylinder 63 rotates, it presses against the limiting blocks 62 through the protrusions, and the limiting blocks 62, under the action of the adjacent springs, prevent the rotating cylinder 63 from passing through; and a trigger rod 64, fixedly connected to the rotating cylinder 63, which presses against the Geneva wheel 52. During rotation, when the trigger rod 64 enters the Geneva wheel 52, it drives the Geneva wheel 52 to rotate.

[0091] Working principle: After the output shaft of the gearbox 42 starts to rotate, the output shaft of the gearbox 42 drives the rotating cylinder 63 to rotate through the third elastic element until the protrusion of the rotating cylinder 63 contacts the limiting block 62. Under the action of the second elastic element on the limiting block 62, the limiting block 62 blocks the rotating cylinder 63, so that the rotating cylinder 63 cannot rotate (that is, at this time the squeezing force applied by the protrusion of the rotating cylinder 63 to the limiting block 62 is insufficient to deflect the limiting block 62). Since the rotating cylinder 63 stops rotating, the third elastic element is stretched by the tension of the output shaft of the gearbox 42 when it rotates.

[0092] During the stretching process of the third elastic element, the squeezing force exerted by the protrusion of the rotating cylinder 63 on the limiting block 62 gradually increases, and at the same time, the force on the second elastic element also gradually increases. When the force accumulated by the third elastic element is greater than the force that the second elastic element can withstand, the limiting block 62 deflects under the action of the second elastic element, so that the protrusion of the rotating cylinder 63 passes through the limiting block 62 and rotates rapidly under the pulling force of the third elastic element until it fits against the next limiting block 62 (while the third elastic element resets).

[0093] During the rotation of the rotating cylinder 63, the rotating cylinder 63 drives the trigger rod 64 to rotate. When the trigger rod 64 is inserted into the Geneva wheel 52, the trigger rod 64 drives the Geneva wheel 52 to rotate rapidly. The Geneva wheel 52 drives the sealing component 53 to rotate. After the trigger rod 64 loses contact with the Geneva wheel 52, the Geneva wheel 52 stops rotating, and the trigger rod 64 continues to rotate and, after two intervals, repeatedly contacts the Geneva wheel 52.

[0094] Thus, the rotating cylinder 63 is limited by the limiting block 62, causing it to rotate intermittently. At the same time, when the rotating cylinder 63 rotates, it is made to rotate rapidly under the action of the third elastic element, thereby driving the sealing component 53 to quickly release the blockage at the connection between the oil supply pipe 9 and the fixed shell 10, and completing the oiling operation.

[0095] After the sealing member 53 releases the blockage at the connection between the oil pipeline 9 and the fixed shell 10, the trigger rod 64 continues to rotate and repeats the above-mentioned action of the trigger rod 64. When the trigger rod 64 contacts the Geneva wheel 52 again, the trigger rod 64 drives the sealing member 53 to rotate again. At this time, the sealing member 53 still does not block the connection between the oil pipeline 9 and the fixed shell 10. Until the trigger rod 64 contacts the Geneva wheel 52 for the third time, the trigger rod 64 drives the sealing member 53 to rotate, so that it blocks the connection between the oil pipeline 9 and the fixed shell 10. All the above processes are repeated.

[0096] like Figures 4-6As shown, it also includes: a stabilizing mechanism, set on the first plate 5, used to control the state of the transmission cylinder 6; the stabilizing component includes: a limiting rod 501, fixedly connected to the first plate 5, one side of the limiting rod 501 being hemispherical; a second plate 502, rotatably connected to the transmission cylinder 6 and slidably connected to the limiting rod 501, and a fourth elastic element, which is a spring, is installed between the limiting rod 501 and the second plate 502 to drive the limiting rod 501 to reset; a third plate 503, fixedly connected to the transmission cylinder 6, and provided with circumferentially distributed limiting holes, the limiting rod 501 being limited and engaged with the limiting holes, when the limiting rod 501 is inserted into the limiting holes, the first plate 5 becomes rigidly connected to the transmission cylinder 6 through the limiting rod 501 and the third plate 503, thus reducing the reciprocating rotation during the rotation of the transmission cylinder 6 and improving the stability of the device during operation.

[0097] Working principle: During the rotation of the transmission cylinder 6, the weight of the bottled water on the conveyor belt 2 causes the transmission cylinder 6 to experience resistance and change its rotation speed. However, the weight of the bottled water on the conveyor belt 2 is not constant, which causes the rotation speed of the transmission cylinder 6 to change constantly. This leads to frequent movement of the extrusion cylinder 21, thereby increasing the wear between parts. To solve the above problems, the following method is proposed.

[0098] During the process of the first plate 5 driving the transmission cylinder 6 to rotate through the first elastic element, the first plate 5 drives the limiting rod 501 to rotate, and the limiting rod 501 drives the second plate 502 to rotate. Since the limiting rod 501 is inserted into the limiting hole of the third plate 503, the first plate 5 drives the transmission cylinder 6 to rotate through the limiting rod 501 and the third plate 503.

[0099] During the rotation of the transmission cylinder 6, the first plate 5 is rigidly connected to the transmission cylinder 6, and the first plate 5 directly drives the transmission cylinder 6 to rotate. During this process, the transmission cylinder 6 is not affected by the resistance brought by the bottled water on the conveyor belt 2, so the transmission cylinder 6 can rotate stably, thereby reducing the speed fluctuation of the transmission cylinder 6 and reducing the wear between parts.

[0100] When the resistance experienced by the transmission cylinder 6 is greater than the limiting force of the limiting rod 501 on the upper limit hole of the third plate 503, the transmission cylinder 6 drives the third plate 503 to rotate. The limiting hole on the third plate 503 squeezes the limiting rod 501, the limiting rod 501 moves under pressure and compresses the fourth elastic element, the limiting rod 501 disengages from the upper limit hole of the third plate 503, the transmission cylinder 6 rotates and the first elastic element stores force. When the limiting rod 501 aligns with the adjacent limiting hole on the third plate 503, the limiting rod 501 re-inserts into the adjacent limiting hole on the third plate 503, and the transmission cylinder 6 is fixed again. The first elastic element continues to store force, and the above process is repeated.

[0101] like Figures 9-12 and Figure 14As shown, it also includes: a counting component, set on the reduction gearbox 42, used to detect the number of rotations of the conveyor belt 2; the counting component includes: a gear 71, rotatably connected to the reduction gearbox 42, the gear 71 is an existing gear structure, its specific number of teeth is modified according to the actual length of the conveyor belt 2, when the conveyor belt 2 rotates once, the number of rotations of the sprocket 7 is the number of teeth of the gear 71, the gear 71 is fixedly connected to a reset rod 72, the reset rod 72 is pressed into the Geneva wheel 52, the structure of the reset rod 72 is the same as the structure of the trigger rod 64, which is also for driving; a plug rod 73, slidably connected to the sprocket 7, and a fifth elastic joint is provided between the two. The fifth elastic element is a tension spring, used to drive the insertion rod 73 to reset. The insertion rod 73 is pressed into the gear component 71. When the insertion rod 73 is inserted into the gear component 71, the insertion rod 73 drives the gear component 71 to rotate. During the rotation of the gear component 71, the trigger rod 64 also rotates slowly, but when the gear component 71 rotates one revolution, the trigger rod 64 does not rotate one revolution. The support ring 74 is fixed to the fixed rod 51. The support ring 74 is provided with a protrusion 75, which is pressed into the insertion rod 73. Both sides of the protrusion 75 are provided with inclined surfaces to facilitate pressing the insertion rod 73. The reset assembly is set on the support frame 1 and is used to drive the first plate 5 to slide.

[0102] The maintenance of existing chain conveyors is carried out periodically, and the chain and sprockets are not constantly being oiled. When oiling the sprockets, it is necessary to ensure that the chain on the conveyor belt 2 is in uniform contact with the lubricating oil before the maintenance is considered complete.

[0103] During the rotation of the fixed rod 51 (the process of the sealing member 53 releasing the seal), the fixed rod 51 drives the support ring 74 to rotate, the support ring 74 drives the protrusion 75 on it to rotate, the protrusion 75 squeezes the insertion rod 73, the fifth elastic member is stretched, and the insertion rod 73 is inserted between the adjacent teeth of the gear member 71. At this time, the sealing member 53 releases the seal and begins to apply oil.

[0104] During the process of the conveyor belt 2 driving the sprocket 7 to rotate, when the insertion rod 73 is inserted between the adjacent teeth of the gear component 71, the sprocket 7 drives the insertion rod 73 to rotate, and the insertion rod 73 moves the gear component 71, causing the gear component 71 to rotate. Thus, for every rotation of the sprocket 7, the insertion rod 73 moves the gear component 71. When the conveyor belt 2 rotates once, the number of rotations of the sprocket 7 is the same as the number of times the gear component 71 is moved, and at the same time, the gear component 71 rotates once.

[0105] During the rotation of gear component 71, gear component 71 drives reset rod 72 to rotate. When reset rod 72 is inserted into Geneva wheel 52, Geneva wheel 52 rotates slowly as gear component 71 rotates (the direction of rotation at this time is opposite to the direction of rotation when trigger rod 64 drives Geneva wheel 52 to rotate). Geneva wheel 52 drives protrusion 75 to rotate, and protrusion 75 gradually loses pressure on insertion rod 73, causing insertion rod 73 to disengage from gear component 71. At the same time, Geneva wheel 52 drives sealing component 53 to rotate, causing sealing component 53 to re-seal the connection between oil pipe 9 and fixed shell 10, thereby stopping the oiling of sprocket 7. In this way, the amount of oil applied to sprocket 7 is controlled by the number of rotations of gear component 71, and the entire chain on conveyor belt 2 is oiled.

[0106] During the rotation of gear component 71, gear component 71 drives the first plate 5 to move through the reset assembly, thereby making the first plate 5 and the transmission cylinder 6 softly connected, and then the transmission cylinder 6 is reset under the torque of the first elastic element.

[0107] like Figures 4-6 and Figure 15 As shown, the reset assembly includes: a rotating rod 81, rotatably connected to the support frame 1, the rotating rod 81 and the gear component 71 are connected through a third transmission component, the third transmission component being a pulley belt, that is, the gear component 71 drives the rotating rod 81 to rotate through the pulley belt; a pressing rod 82, rotatably connected to the support frame 1, the pressing rod 82 and the rotating rod 81 are connected through a bevel gear set; and an unlocking rod 83, slidably connected to the support frame 1, and a sixth elastic element, a tension spring, is provided between the two to drive the unlocking rod 83 to reset. The pressing rod 82 is provided with a round rod, and the unlocking rod 83 is provided with an inclined groove. During the rotation, the round rod of the pressing rod 82 enters the inclined groove on the unlocking rod 83 and pushes the inclined groove of the unlocking rod 83 to slide, and the unlocking rod 83 is pressed and engaged with the first plate 5.

[0108] During the rotation of gear component 71, gear component 71 drives rotating rod 81 to rotate through third transmission component. Rotating rod 81 drives pressing rod 82 to rotate through bevel gear set. As pressing rod 82 rotates, the round rod on pressing rod 82 gradually inserts into the inclined groove of unlocking rod 83. Unlocking rod 83 is pressed and gradually moves out of first plate 5.

[0109] After the unlocking rod 83 contacts the first plate 5, the unlocking rod 83 begins to squeeze the first plate 5, causing the first plate 5 to move. The first plate 5 drives the limiting rod 501 on it to move. At the same time, the limiting rod 501 compresses the fourth elastic element and disengages from the limiting hole of the third plate 503, so that the transmission cylinder 6 is no longer subject to limiting force, and thus the transmission cylinder 6 and the first plate 5 are restored to a soft connection. Since the sprocket 7 is being lubricated when the unlocking rod 83 contacts the first plate 5, the friction between the sprocket 7 and the chain on the conveyor belt 2 is reduced, and the resistance of the transmission cylinder 6 is reduced, so the transmission cylinder 6 is reset under the action of the first elastic element. The squeezing cylinder 21 and the sliding rod 24 are also reset, and the resistance of the transmission cylinder 6 is re-detected to repeat the lubrication operation.

[0110] like Figure 8 As shown, it also includes: a shield 4101, which is rotatably connected to the truncated cone wheel 41 and is used to isolate the truncated cone wheel 41. When the sprocket 7 is being oiled, the lubricating oil sprayed out from the sprocket 7 comes into contact with the chain on the conveyor belt 2. The lubricating oil on the chain will drip down under the action of gravity. The shield 4101 shields the truncated cone wheel 41 to prevent the lubricating oil from dripping onto the truncated cone wheel 41 and affecting the transmission.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.
