Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to a lifting and transporting device for bottled water production. Background Art

[0002] In the production process of bottled water, from the selection of water sources to the packaging and distribution of the final product, multiple steps are involved, mainly including water source selection, water quality testing, water treatment, filling, packaging, storage and distribution; in the above process, lifting and transportation devices are used in filling, packaging, storage and distribution. For example, the filled bottles will be moved from one workstation to another (such as from the filling line to the capping line) and the boxed bottled water will be moved from the production line to the warehouse.

[0003] At present, the lifting and transporting devices used in the production process of bottled water include chain conveyors. Chain conveyors rely on the transmission of chains to realize the transportation of bottled water. In order to ensure the stable transmission of power of the chains on the chain conveyors and extend their service life, appropriate amount of lubricating oil is applied to the chains regularly to reduce the friction and wear of the chains. In the process of transporting bottled water, as the weight of the conveyed materials increases, the load of the chains will also increase, thereby increasing the degree of wear between the chains and the sprockets. In this way, more lubricating oil needs to be applied to the chains and the sprockets to ensure lubrication between the two. However, the existing method is to drip oil in a timed and quantitative manner through an oil dripper. If the initial adjustment of the oiling amount is too large, it will lead to waste of lubricating oil. On the contrary, it will lead to increased wear between the sprockets and the chains, thereby affecting their service life. Summary of the invention

DETAILED DESCRIPTION

[0072] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0073] Through research, it is found that an oiler is used for chain maintenance, which mainly applies lubricating oil to the chain in a timed and quantitative manner. However, when the chain conveyor is in operation, when the amount of material on it increases, the friction between the chain and the sprocket increases, thereby increasing the wear of the chain and the sprocket. Therefore, more lubricating oil needs to be applied between the chain and the sprocket, but the flow rate of the existing oiler cannot be adjusted after the initial adjustment, which will increase the friction between the chain and the sprocket, thereby increasing the wear of both.

[0074] A lifting and transporting device for bottled water production, such as Figure 1-Figure 5 As shown, it includes: a support frame 1, a conveyor belt 2 is installed on the support frame 1, and a driving motor 3 is installed on the support frame 1; a spline rod 4 is fixedly connected to the output shaft of the driving motor 3, and the spline rod 4 is slidably connected to the first plate 5; a transmission cylinder 6 is arranged on the first plate 5, and a first elastic member is arranged between the two; a sprocket 7 is fixedly connected to the transmission cylinder 6, and an oil storage cavity is arranged therein, and oil injection ports which are circumferentially distributed and connected to the oil storage cavity are arranged therein, and the sprocket 7 is drivingly connected to the conveyor belt 2; an oil storage tank 8 is installed on the support frame 1, and the sprocket 7 is rotatably connected to the fixed shell 10, the fixed shell 10 is connected to the oil storage cavity of the sprocket 7, and an oil pipeline 9 is connected between the fixed shell 10 and the oil storage tank 8; an extrusion assembly is arranged in the transmission cylinder 6, and is used to detect the state of the transmission cylinder 6.

[0075] In the above scheme, a method for detecting the amount of material on the conveyor belt 2 is provided, through the resistance generated by the amount of material, and the relative rotation of the spline rod 4 and the transmission cylinder 6, so as to control the amount of oil dripping; the first elastic member is a torsion spring, and the first plate 5 drives the transmission cylinder 6 to rotate through the first elastic member, so that the sprocket 7 and the output shaft of the driving motor 3 become a soft connection; the oil injection port on the sprocket 7 is located between two adjacent teeth on it, so as to ensure the oiling operation of the contact position between the sprocket and the chain; the oil storage tank 8 stores lubricating oil, and an oil supply pump is installed therein; this scheme can set the number of sprockets 7 according to actual conditions to ensure the stability of power transmission during material transportation. This article takes 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, and at the same time the first plate 5 drives the transmission cylinder 6 to rotate through the first elastic member, the transmission cylinder 6 drives the sprocket 7 to rotate, and the sprocket 7 drives the conveyor belt 2 thereon to rotate, and thus the bottled water starts to be conveyed.

[0077] When the conveyor belt 2 starts to convey bottled water, the resistance on the sprocket 7 gradually increases, causing relative movement between the transmission cylinder 6 and the first plate 5. In this way, the weight of the bottled water on the conveyor belt 2 can be detected in real time. After the relative movement between the transmission cylinder 6 and the first plate 5 occurs, the load condition of the sprocket is detected by the extrusion assembly to determine the amount of oil to be injected into the sprocket. When the sprocket is oiled, the oil storage tank 8 starts to work and pumps the lubricating oil therein into the fixed shell 10 through the oil pipe 9. Then the lubricating oil enters the oil storage chamber of the sprocket 7 and is sprayed to the contact position of the sprocket and the chain through the oil injection hole, thereby completing the oiling work.

[0078] Further, such as Figure 4-Figure 6 As shown, the extrusion assembly includes: an extrusion cylinder 21, which is arranged in the transmission cylinder 6, and the extrusion cylinder 21 is fixedly connected with a support rod 22, and the support rod 22 is slidably connected to the spline rod 4; a limiting ball 23, which is fixedly connected to the extrusion cylinder 21, and a thread groove is arranged in the transmission cylinder 6, and the number of thread grooves shown in the figure is three, and the number of limiting balls 23 is also three, and the limiting balls 23 are extrusion-fitted with the thread groove; a sliding rod 24, which is slidably connected to the support frame 1, and the sliding rod 24 is extrusion-fitted with the extrusion cylinder 21; a speed detection assembly, which is arranged on the support frame 1, and is used to detect the moving speed of the conveyor belt 2.

[0079] In the above scheme, a method is provided 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, so as to ensure that the rotation speed of the extrusion cylinder 21 is consistent with that of the spline rod 4; an arc-shaped surface is provided on one side of the extrusion cylinder 21, and at the same time, an inclined surface is provided on the side of the sliding rod 24 close to the extrusion cylinder 21; the length of the inner thread groove of the extrusion cylinder 21 in the horizontal direction is equal to the diameter of the sliding rod 24, so as to ensure that the arc-shaped surface of the extrusion cylinder 21 is always in contact with the inclined surface of the sliding rod 24 during the sliding process of the extrusion cylinder 21 along the thread groove of the transmission cylinder 6.

[0080] Working principle: When the sprocket 7 drives the chain on the conveyor belt 2 to rotate, the sprocket 7 generates a speed difference between the transmission cylinder 6 and the spline rod 4, and as the material on the conveyor belt 2 increases, the relative rotation angle between the transmission cylinder 6 and the spline rod 4 increases, thereby causing the transmission cylinder 6 and the extrusion cylinder 21 to rotate relative to each other; the number of support rods 22 in the present 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 in the extrusion cylinder 21, and then causing the limiting ball 23 to drive the extrusion cylinder 21 to slide through the support rod 22, so that the extrusion cylinder 21 slides out of the transmission cylinder 6.

[0082] When the extrusion cylinder 21 slides outward from the transmission cylinder 6 , the extrusion cylinder 21 squeezes the sliding rod 24 , thereby causing the sliding rod 24 to move leftward.

[0083] Further, such as Figure 4 , Figure 7 and Figure 8 As shown, the speed detection component includes: a transmission rod 31, which is rotatably connected to the support frame 1 and spline-connected to the sliding rod 24; a detection wheel 32, which is rotatably connected to the support frame 1 and fits with the conveyor belt 2. A rubber layer is provided on the outer side of the detection wheel 32 to increase its friction. During the movement of the conveyor belt 2, the detection wheel 32 is driven to rotate by the friction between the conveyor belt 2 and the detection wheel 32. The transmission rod 31 is connected to the detection wheel 32 through a first transmission member. The first transmission member in the present invention is specifically a straight rod, a set of pulley belts and a set of bevel gears. The detection wheel 32 and the straight rod are driven by the pulley belt, and the straight rod and the transmission rod 31 are connected by the bevel gear. The first transmission member does not specifically refer to the above description 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; a transmission reduction assembly is provided on the support frame 1, and is used to reduce the output speed of the detection wheel 32.

[0084] Further, such as Figure 4 , Figure 7 and Figure 8 As shown, the transmission reduction assembly includes: a conical wheel 41, which is rotatably connected to the support frame 1 and frictionally matched with the sliding rod 24. The diameter of the conical wheel 41 on the side close to the detection wheel 32 is smaller than the diameter on the side away from the detection wheel 32. By changing the contact position of the sliding rod 24 and the conical wheel 41, the transmission ratio between the two is changed; a reduction box 42; installed on the support frame 1, the input shaft of the reduction box 42 is transmission-connected to the conical wheel 41 through a second transmission member. The reduction box 42 is an existing device, and its internal structure is not repeated here. The second transmission member is composed of a set of pulley belts, a straight rod and a bevel gear set, wherein the conical wheel 41 drives the straight rod to rotate through the bevel gear set, and the straight rod drives the input shaft of the reduction box 42 to rotate through the pulley belt. The second transmission member has the same function as the first transmission member, both for transmitting power. The structure shown in the present invention is only an example and can be changed according to specific circumstances; a blocking assembly, which is arranged on the reduction box 42 and is used to block the connection between the oil pipeline 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 member, the transmission rod 31 drives the sliding rod 24 to rotate, the sliding rod 24 drives the conical wheel 41 to rotate, the conical wheel 41 drives the input shaft of the reduction box 42 to rotate, and the output shaft of the reduction box 42 rotates slowly (that is, the rotation speed of the output shaft of the reduction box 42 is much smaller than the rotation speed of the input shaft of the reduction box 42).

[0086] When the sliding rod 24 moves to the left, the transmission ratio between the sliding rod 24 and the conical wheel 41 increases, thereby increasing the rotation speed of the conical wheel 41. As the weight of the bottled water on the conveyor belt 2 increases, the sliding rod 24 moves farther to the left, making the rotation speed of the conical wheel 41 faster, thereby increasing the amount of lubricating oil applied to the chain.

[0087] During the rotation of the output shaft of the reduction box 42, the reduction box 42 releases the blockage of the connection between the oil pipe 9 and the fixed shell 10 through the blocking component, so that the lubricating oil flows into the fixed shell 10 along the oil pipe 9, thus completing the oiling work.

[0088] Further, such as Figure 9-11 and Fig.14As shown, the blocking assembly includes: a fixed rod 51, which is rotatably connected to the reduction box 42 and is rotatably connected to the transmission cylinder 6; a Geneva wheel 52, which is fixed 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 the present invention, the single rotation angle of the Geneva wheel 52 is 60°; a blocking member 53, which is fixed to the fixed rod 51 and is slidably connected to the fixed shell 10 and the sprocket 7. The blocking member 53 blocks the connection between the oil pipeline 9 and the fixed shell 10. The blocking member 53 is composed of a circular ring, a straight rod and a blocking block, wherein the circular ring, the sprocket 7 and the fixed shell 10 form a closed cavity, which is used to store lubricating oil, and the blocking block is used to block the connection between the oil pipeline 9 and the fixed shell 10, so as to control the flow of lubricating oil; a trigger assembly, which is arranged on the reduction box 42, and is used to control the movement of the Geneva wheel 52.

[0089] Working principle: After the output shaft of the above-mentioned reduction gearbox 42 starts to rotate, the output shaft of the reduction gearbox 42 controls the rotation of the Geneva wheel 52 through the trigger assembly, the Geneva wheel 52 drives the fixed rod 51 to rotate, the fixed rod 51 drives the blocking member 53 to rotate, and the blocking member 53 releases the blockage of the connection between the oil delivery pipe 9 and the fixed shell 10, so that the lubricating oil is discharged from the oil injection hole of the sprocket 7.

[0090] Further, such as Fig. 9 and Fig.10 and Fig.13 As shown, the trigger assembly includes: a fixed cylinder 61, which is fixedly connected to the reduction box 42, and a plurality of limit blocks 62 are arranged in the fixed cylinder 61 through a second elastic member, the second elastic member is a spring, and three limit blocks 62 are arranged evenly distributed in the circumferential direction in the present invention, and the limit blocks 62 are arranged with inclined surfaces; a rotating cylinder 63, which is rotatably connected to the output shaft of the reduction box 42, and a third elastic member is fixedly connected therebetween, the third elastic member is a tension spring, and three protrusions evenly distributed in the circumferential direction are arranged on the outer side of the rotating cylinder 63, and the protrusions are pressed and matched with adjacent limit blocks 62. When the rotating cylinder 63 rotates, the rotating cylinder 63 presses the limit blocks 62 through the protrusions thereon, and at this time, the limit blocks 62 block the rotating cylinder 63 from passing through under the action of the adjacent springs; a trigger rod 64, which is fixedly connected to the rotating cylinder 63, and the trigger rod 64 is pressed and matched with the Geneva wheel 52. When the trigger rod 64 rotates, when the trigger rod 64 enters the Geneva wheel 52, the trigger rod 64 drives the Geneva wheel 52 to rotate.

[0091] Working principle: after the output shaft of the reduction gear box 42 starts to rotate, the output shaft of the reduction gear box 42 drives the rotating cylinder 63 to rotate through the third elastic member until the protrusion of the rotating cylinder 63 contacts the limit block 62. The limit block 62 blocks the rotating cylinder 63 under the action of the second elastic member thereon, so that the rotating cylinder 63 cannot rotate (that is, at this time, the extrusion force applied by the protrusion of the rotating cylinder 63 to the limit block 62 is not sufficient to deflect the limit block 62). Since the rotating cylinder 63 stops rotating, the third elastic member is stretched by the pulling force when the output shaft of the reduction gear box 42 rotates.

[0092] During the stretching of the third elastic member, the extrusion pressure exerted by the protrusion of the rotating cylinder 63 on the limit block 62 gradually increases, and the force exerted on the second elastic member also gradually increases. When the force accumulated by the third elastic member is greater than the force that the second elastic member can withstand, the limit block 62 is deflected under the action of the second elastic member, so that the protrusion of the rotating cylinder 63 passes through the limit block 62 and rotates quickly under the pulling force of the third elastic member until it fits with the next limit block 62 (the third elastic member is reset at the same time).

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

[0094] In this way, the rotating cylinder 63 is limited by the limit block 62 to make it rotate intermittently. At the same time, when the rotating cylinder 63 rotates, it is caused to rotate rapidly under the action of the third elastic member, thereby transmitting the blocking member 53 to quickly release the blockage of the connection between the oil delivery pipe 9 and the fixed shell 10, completing the oiling operation.

[0095] After the blocking member 53 releases the blockage of 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 blocking member 53 to rotate again. At this time, the blocking 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 blocking member 53 to rotate, so that it blocks the connection between the oil pipeline 9 and the fixed shell 10, and all the above-mentioned processes are repeated.

[0096] like Figure 4-Figure 6As shown, it also includes: a stabilizing mechanism, which is arranged on the first plate 5 and is used to control the state of the transmission cylinder 6; the stabilizing component includes: a limiting rod 501, which is fixedly connected to the first plate 5, and one side of the limiting rod 501 is set to be hemispherical; the second plate 502, which is rotatably connected to the transmission cylinder 6 and is slidably connected to the limiting rod 501, and a fourth elastic member is installed between the limiting rod 501 and the second plate 502, and the fourth elastic member is a spring, which is used to drive the limiting rod 501 to reset; the third plate 503, which is fixedly connected to the transmission cylinder 6 and is provided with circumferentially distributed limiting holes, and the limiting rod 501 is limitedly matched with the limiting hole. When the limiting rod 501 is inserted into the limiting hole, the first plate 5 is hard-connected with the transmission cylinder 6 through the limiting rod 501 and the third plate 503, thereby reducing the reciprocating rotation of the transmission cylinder 6 during rotation and improving the stability of the device during operation.

[0097] Working principle: During the rotation of the transmission cylinder 6, the transmission cylinder 6 is affected by the gravity of the bottled water on the conveyor belt 2, which causes resistance to the transmission cylinder 6 and changes its rotation speed. However, the gravity of the bottled water on the conveyor belt 2 is not fixed, which causes the rotation speed of the transmission cylinder 6 to change all the time. This will cause the extrusion cylinder 21 to move frequently, thereby increasing the wear between parts. In order to solve the above problem, the following method is proposed.

[0098] When the first plate 5 drives the transmission cylinder 6 to rotate via the first elastic member, 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 via 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 rotation 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, and 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 member. The limiting rod 501 disengages from the upper limit hole of the third plate 503, and the transmission cylinder 6 rotates and causes the first elastic member to accumulate force. When the limiting rod 501 is aligned with the adjacent limiting hole on the third plate 503, the limiting rod 501 is reinserted into the adjacent limiting hole on the third plate 503 to re-fix the transmission cylinder 6, and the first elastic member continues to accumulate force, and the above process is repeated subsequently.

[0101] like Figure 9-12 and Fig.14As shown, it also includes: a counting component, which is arranged on the reduction box 42 and is used to detect the number of rotations of the conveyor belt 2; the counting component includes: a gear member 71, which is rotatably connected to the reduction box 42, and the gear member 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 one circle, the number of circles rotated by the sprocket 7 is the number of teeth of the gear member 71. The gear member 71 is fixedly connected to a reset rod 72, and the reset rod 72 is squeezed and matched with the Geneva wheel 52. The structure of the reset rod 72 is consistent with that of the trigger rod 64, and they are also used for driving; a plug-in rod 73, which is slidably connected to the sprocket 7, and a fifth elastic member is provided between the two. The fifth elastic member is a tension spring, which is used to drive the plug-in rod 73 to reset. The plug-in rod 73 is squeezed and matched with the gear member 71. When the plug-in rod 73 is inserted into the gear member 71, the plug-in rod 73 drives the gear member 71 to rotate. During the process of the gear member 71 rotating one circle, the trigger rod 64 also rotates slowly, but when the gear member 71 rotates one circle, the trigger rod 64 does not rotate one circle; the support ring 74 is fixed to the fixed rod 51, and the support ring 74 is provided with a protrusion 75. The protrusion 75 is squeezed and matched with the plug-in rod 73, and inclined surfaces are provided on both sides of the protrusion 75 to facilitate the squeezing of the plug-in rod 73; the reset component is arranged on the support frame 1, and is used to drive the first plate 5 to slide.

[0102] The maintenance work of the existing chain conveyor is carried out regularly, and the chain and sprocket are not always oiled. At the same time, when the sprocket is oiled, it is necessary to ensure that the chain on the conveyor belt 2 is in uniform contact with the lubricating oil, so that the maintenance is completed.

[0103] During the rotation of the fixed rod 51 (the process of unblocking the blocking member 53), the fixed rod 51 drives the support ring 74 to rotate, and the support ring 74 drives the protrusion 75 thereon to rotate. The protrusion 75 squeezes the plug-in rod 73, and the fifth elastic member is stretched. The plug-in rod 73 is inserted between adjacent teeth of the gear member 71. At this time, the blocking member 53 is unblocked and starts to be oiled.

[0104] When the conveyor belt 2 drives the sprocket 7 to rotate, when the connecting rod 73 is inserted between adjacent teeth of the gear part 71, the sprocket 7 drives the connecting rod 73 to rotate, and the connecting rod 73 moves the gear part 71, and causes the gear part 71 to rotate. Therefore, every time the sprocket 7 rotates one circle, the connecting rod 73 moves the gear part 71. When the conveyor belt 2 rotates one circle, the number of rotations of the sprocket 7 is consistent with the number of times the gear part 71 is fluctuated, and the gear part 71 rotates one circle at the same time.

[0105] During the rotation of gear member 71, gear member 71 drives reset rod 72 to rotate. When reset rod 72 is inserted into Geneva wheel 52, as gear member 71 rotates, Geneva wheel 52 slowly rotates (the rotation direction at this time is opposite to the rotation direction when trigger rod 64 drives Geneva wheel 52 to rotate), and Geneva wheel 52 drives protrusion 75 to rotate. Protrusion 75 gradually loses the squeeze on plug-in rod 73, so that plug-in rod 73 is out of contact with gear member 71. At the same time, Geneva wheel 52 drives blocking member 53 to rotate, so that blocking member 53 re-blocks the connection between oil delivery pipe 9 and fixed shell 10, and then stops oiling sprocket 7. In this way, the oiling amount of sprocket 7 is controlled by the number of rotations of gear member 71, and the chain on conveyor belt 2 is oiled as a whole.

[0106] During the rotation of the gear member 71 , the gear member 71 drives the first plate 5 to move through the reset assembly, so that the first plate 5 and the transmission cylinder 6 become softly connected, and the transmission cylinder 6 is reset under the torsion of the first elastic member.

[0107] like Figure 4-Figure 6 and Fig.15 As shown, the reset assembly includes: a rotating rod 81, which is rotatably connected to the support frame 1, and the rotating rod 81 is connected to the gear member 71 through a third transmission member, and the third transmission member is a pulley belt, that is, the gear member 71 drives the rotating rod 81 to rotate through the pulley belt; an extrusion rod 82, which is rotatably connected to the support frame 1, and the extrusion rod 82 and the rotating rod 81 are connected through a bevel gear set; an unlocking rod 83, which is slidably connected to the support frame 1, and a sixth elastic member is arranged between the two, and the sixth elastic member is a tension spring, which is used to drive the unlocking rod 83 to reset, a round rod is arranged on the extrusion rod 82, and an inclined groove is arranged on the unlocking rod 83, the round rod of the extrusion rod 82 enters the inclined groove on the unlocking rod 83 during rotation, and pushes the inclined groove of the unlocking rod 83 to slide, and the unlocking rod 83 is squeezed and matched with the first plate 5.

[0108] During the rotation of the gear member 71, the gear member 71 drives the rotating rod 81 to rotate through the third transmission member, and the rotating rod 81 drives the squeezing rod 82 to rotate through the bevel gear set. As the squeezing rod 82 rotates, the round rod on the squeezing rod 82 is gradually inserted into the inclined groove of the unlocking rod 83, and the unlocking rod 83 is pressed and gradually moves toward the 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 start moving, and the first plate 5 drives the limiting rod 501 thereon to move. At the same time, the limiting rod 501 compresses the fourth elastic member and disengages from the limiting hole of the third plate 503, so that the transmission cylinder 6 is not subject to limiting force, and the transmission cylinder 6 and the first plate 5 are restored to a soft connection. Since the sprocket 7 is being oiled 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 experienced by the transmission cylinder 6 is reduced, so that the transmission cylinder 6 is reset under the action of the first elastic member, the extrusion cylinder 21 and the sliding rod 24 are both reset, and the resistance experienced by the transmission cylinder 6 is re-tested to repeat the oiling operation.

[0110] like Figure 8 As shown, it also includes: a shielding cover 4101, which is rotatably connected to the conical wheel 41 and is used to isolate the conical wheel 41. When the sprocket 7 is oiled, the lubricating oil sprayed from the sprocket 7 contacts the chain on the conveyor belt 2, and the lubricating oil on the chain will drip downward due to the action of gravity. The shielding cover 4101 is used to shield the conical wheel 41 to prevent the lubricating oil from dripping onto the conical wheel 41 and affecting the transmission.
