Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of filling machines, and specifically to a six-head barrel automatic filling machine. Background Art
[0002] The filling of liquid fertilizers is an important link in agricultural production. In the filling process of traditional filling machines, the problem of liquid splashing easily occurs, which not only affects the filling efficiency, but also may cause liquid waste and equipment pollution. To solve this problem, the existing six-head automatic filling machines usually adopt the design of deeply inserting the filling heads into the interior of the filling barrels to shorten the distance between the filling heads and the liquid surface, thereby reducing the splashing phenomenon, as Figure 10 shown.
[0003] An existing filling machine, such as a sesame oil automatic filling machine proposed in the patent application number "CN214935938U", includes a filling machine frame, an oil storage tank, and a filling platform. The oil storage tank and the filling platform are both arranged on the filling machine frame. An inlet hopper is arranged on the oil storage tank, and an oil injection assembly is further included; the oil injection assembly includes an oil pump, an oil suction pipe, an oil delivery pipe, a shunt box, and multiple oil injection pipes; the oil pump and the shunt box are both arranged on the filling machine frame. One end of the oil suction pipe is communicated with the bottom wall of the oil storage tank, and the other end is communicated with the pump inlet end of the oil pump; one end of the oil delivery pipe is communicated with the pump outlet end of the oil pump, and the other end is communicated with the shunt box; one ends of the multiple oil injection pipes are communicated with the shunt box and the other ends extend downward, and an oil injection valve is arranged on the oil injection pipe; an oil barrel for packaging sesame oil is placed on the filling platform.
[0004] When the above patent is actually used, since the outlet ends of the multiple oil injection pipes are all connected to the lifting assembly, when the lifting cylinder drives the grouting pipe to descend and extend into the interior of the oil barrel, to a certain extent, it prevents the sesame oil in the oil injection pipe from spilling out of the oil barrel. However, in actual use, this design method also brings new problems. Since the grouting pipe is in contact with the liquid for a long time, the liquid is easily adhered to the outer surface of the grouting pipe. When the grouting pipe withdraws from the oil barrel, these adhered liquids will gradually accumulate and form residues that are difficult to clean after contacting the air. Over time, these residues may accumulate and deteriorate, and even breed microorganisms. With the repeated use of the grouting pipe, these deteriorated liquids may be brought into a new oil barrel and come into contact with the liquid in the new oil barrel, thereby affecting the quality of the newly filled liquid.

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] A six-head barrel automatic filling machine, in which the filling machine cleans the filling heads regularly. As Figure 7 shown, the Z-shaped scraper is used in cooperation with the cleaning mechanism to clean the adhesive stains on the surface of the filling heads, which belongs to a kind of storage device and improves the storage quality.
[0023] As Figures 1 - 7As shown, it includes a filling machine case 1, a transport trough 2 is provided at the inner bottom of the filling machine case 1, a conveyor belt 3 is arranged inside the transport trough 2, six filling barrels 4 are evenly placed on the top of the conveyor belt 3, the interior of the filling machine case 1 is symmetrically fixedly connected with lifting slide bars 5, one end of the two lifting slide bars 5 is slidably connected to the lifting platform 6, one end of the lifting platform 6 is evenly rotatably connected to six hinge blocks 7, one end of the hinge block 7 is fixedly connected to the filling plug 8, three filling pumps 9 are evenly fixedly connected inside the filling machine case 1, the output end of the filling pump 9 is fixedly connected to the shunt pipe 10, the output end of the shunt pipe 10 is fixedly connected to the corresponding two filling plugs 8 through the drainage pipe 11, one end of the filling machine case 1 is rotatably connected with six Z-shaped scrapers 12 adapted to the filling plug 8, one end of the filling machine case 1 is installed with an adjustment mechanism for adjusting the working form of the filling plug 8, and one end of the filling machine case 1 is installed with a cleaning mechanism for driving the Z-shaped scraper 12 to complete the cleaning of the stains on the surface of the filling plug 8, and one end of the filling machine case 1 is installed with a sensor component.
[0024] When in use, first, set the working cycle and sleep time of the sensor component, and set multiple TE Connectivity Model 3130 gravity sensors corresponding to the filling barrels 4 inside the conveyor belt 3. When the conveyor belt 3 is started and the six filling barrels 4 are moved to the bottom of the filling plug 8, the adjustment mechanism is activated to drive the lifting platform 6 to drive the multiple filling plugs 8 to be inserted downward along the length direction of the lifting slide bar 5 into the filling barrel 4, and at the same time, the gravity sensor is used to monitor the gravity of the liquid fertilizer filled in the filling barrel in real time. Subsequently, the filling pump 9 is started to connect to the external storage tank, and the liquid fertilizer is input into the filling plug 8 through the shunt pipe 10 and the drainage pipe 11, and the liquid fertilizer is poured into the filling barrel 4 through the filling plug 8; Next, when the TE Connectivity Model 3130 gravity sensor detects that the liquid fertilizer inside the filling barrel 4 has been filled to the preset value, the regulating mechanism is started in the reverse direction to drive the lifting platform 6 to drive the multiple filling plugs 8 to move upward along the length direction of the lifting slide bar 5 for a certain distance, so that the lifting platform 6 drives the filling plugs 8 to separate from the filling barrel 4, and completes the process of inserting the filling plugs 8 into the filling barrel 4 for filling, effectively reducing the splashing of liquid fertilizer. After the preset time is reached, the regulating mechanism is started in the reverse direction to drive the lifting platform 6 to move upward along the length direction of the lifting slide bar 5 for another distance, and drives the hinge block 7 to rotate 90° around the hinge axis, so that one end of the hinge block 7 fits with the Z-shaped scraper 12. At this time, the sensor component is triggered to control the cleaning mechanism to drive the Z-shaped scraper 12 to rotate around the periphery of the filling plug 8, scrape off the stains adhering to the periphery of the filling plug 8, so that the stains are detached and attracted and collected; Then, start the adjustment mechanism again, drive the lifting platform 6 to move downward along the length direction of the lifting slide rod 5 for another stroke, so that the lifting platform 6 drives the filling plug 8 back to the position just above the filling barrel 4 where it has just separated from the filling barrel 4, and make the cleaning mechanism drive the hinge block 7 and the filling plug 8 to rotate 90° around the hinge axis and return to the state parallel to the filling barrel 4, which is convenient for automatically cleaning the periphery of the filling plug 8 regularly. This process effectively reduces the accumulation of stains on the periphery of the filling plug 8, avoids the growth of microorganisms, and ensures the quality of the subsequent newly filled liquid.
[0025] As Figures 3 - 6 shown, the adjustment mechanism includes a moving rack 13 fixedly connected to one end of the lifting platform 6, a fixed rack 14 fixedly connected to the inner side of the filling machine case 1, and a first electric push rod 15 fixedly connected to the inner side of the filling machine case 1. The output end of the first electric push rod 15 is rotatably connected to a lifting gear 16. The lifting gear 16 is synchronously engaged with the moving rack 13 and the fixed rack 14. A transmission assembly for driving the hinge block 7 to rotate is installed at one end of the lifting platform 6; Among them, the transmission assembly includes six pairs of guiding slide rods 17 uniformly fixedly connected to the top of the lifting platform 6. One end of a pair of guiding slide rods 17 is slidably connected to a transmission rack 18. A transmission gear 19 engaged with the transmission rack 18 is fixedly connected to the hinged end of the hinge block 7. A lower abutting block 20 is fixedly connected to the top of the transmission rack 18. Six upper abutting blocks 21 adapted to the lower abutting block 20 are uniformly fixedly connected to the inner side of the filling machine case 1; And, a return spring 22 is sleeved at one end of the guiding slide rod 17, and the return spring 22 is installed between the transmission rack 18 and the lifting platform 6; And, the sensing assembly includes a control panel 35 fixedly connected to one end of the filling machine case 1. Six photoelectric switches 36 are uniformly fixedly connected to one end of the lifting platform 6. An arc-shaped light-shielding plate 37 adapted to the photoelectric switch 36 is fixedly connected to one end of the hinge block 7. The control panel 35 is electrically connected to the first electric push rod 15 and the photoelectric switches 36. The photoelectric switch 36 belongs to the Omron E3Z-D81 diffuse reflection type photoelectric sensor.
[0026] During use, first, start the first electric push rod 15 to push the lifting gear 16 to move downward along the length direction of the lifting slide rod 5, and at the same time ensure that the lifting gear 16 is synchronously engaged with the moving rack 13 and the fixed rack 14. During the movement, the lifting gear 16 not only moves along the length direction of the fixed rack 14, but also rotates, continues to engage with the moving rack 13, and pushes the lifting platform 6 to move along the length direction of the lifting slide rod 5, thereby driving the hinge block 7 and the filling plug 8 to move along the length direction of the lifting slide rod 5; Subsequently, when the lifting platform 6 drives the hinge block 7 to move downward to a certain stroke along the length direction of the lifting slide bar 5, the hinge block 7 will drive the filling plug 8 to be inserted into the filling barrel 4 along the length direction of the lifting slide bar 5 for filling. When the lifting platform 6 drives the hinge block 7 to move upward along the length direction of the lifting slide bar 5 for another stroke, the lifting platform 6 pushes the transmission rack 18 to move upward along the length direction of the guide slide bar 17, and makes the lower resistance block 20 contact the upper resistance block 21, causing the lower resistance block 20 to drive the transmission rack 18 to engage with the transmission gear 19. This will squeeze the reset spring 22 to produce a contraction deformation and accumulate elastic potential energy. At the same time, the transmission gear 19 drives the hinge block 7 and the filling plug 8 to rotate upward around the hinge axis, thereby making the filling plug 8 fit tightly with one end of the Z-shaped scraper 12; In addition, in the process of driving the transmission rack 18 to mesh with the transmission gear 19, when the transmission gear 19 drives the hinge block 7 to rotate upward by 90°, the hinge block 7 will drive the arc-shaped shading plate 37 to shield one end of the photoelectric switch 36 around the hinge axis, and at the same time, the arc-shaped shading plate 37 blocks the light output by the transmitter of the photoelectric switch 36, and makes the reflected light unable to return to the receiver of the photoelectric switch 36, thereby triggering the photoelectric switch 36, and controlling the cleaning mechanism through the control panel 35 to drive the Z-shaped scraper 12 to rotate and scrape the periphery of the filling plug 8 to clean; Next, in the process of driving the lifting platform 6 to drive the filling plug 8 to move to the position just out of the top of the filling barrel 4, the reset spring 22 releases its elastic potential energy and pushes the transmission rack 18 to move along the length direction of the guide slide bar 17 and form a conflict with the top of the guide slide bar 17, so as to reduce the meshing of the transmission rack 18 and the transmission gear 19, thereby reducing the situation that the filling direction of the filling plug 8 is affected, thereby improving the accuracy of the device.
[0027] like Figure 2 and Figure 3 , Figure 7 , Figure 8 As shown, the cleaning mechanism includes a worm gear 24 fixedly connected to the shaft end of a Z-shaped scraper 12, one end of the filling machine box 1 is rotatably connected to a worm 25 meshing with the worm gear 24, one end of the filling machine box 1 is fixedly connected to a cleaning motor 26, the output end of the cleaning motor 26 is fixedly connected to the worm 25, one end of the Z-shaped scraper 12 is installed with a synchronization component for driving multiple Z-shaped scrapers 12 to rotate synchronously, and one end of the filling machine box 1 is installed with a suction component for absorbing residual stains on the surface of the filling plug 8; The synchronous assembly includes a synchronous wheel 27 fixedly connected to the shaft end of the Z-shaped scraper 12, and a synchronous belt 28 is provided on the outer periphery of the plurality of synchronous wheels 27; Moreover, the suction assembly includes six Z-shaped adsorption rods 29 uniformly and fixedly connected to one end of the filling machine case 1. The Z-shaped adsorption rods 29 are installed above the Z-shaped scraper 12. A main through groove 30 is formed inside the Z-shaped adsorption rods 29, and a pair of adsorption grooves 31 communicating with the main through groove 30 are symmetrically formed at the bottom of the Z-shaped adsorption rods 29. One end of the filling machine case 1 is fixedly connected with an adsorption pump 32. The input end of the adsorption pump 32 is fixedly connected with a manifold rod 33. The input ends of the manifold rod 33 are respectively communicated with the six main through grooves 30. One end of the filling machine case 1 is fixedly connected with a sewage collection box 34. The output end of the adsorption pump 32 is communicated with the inside of the sewage collection box 34.
[0028] During use, the adjustment assembly drives the hinge block 7 to start, driving the filling plug 8 to rotate upward by 90 degrees around the hinge axis. When it is in close fit with one end of the Z-shaped scraper 12, the sensing assembly is triggered. Subsequently, the cleaning motor 26 drives the worm 25 to start rotating, and at the same time meshes the worm 25 with the worm gear 24, thereby driving the worm gear 24 to rotate the Z-shaped scraper 12. By the synergistic effect of the synchronous belt 28 and the synchronous pulley 27, one end of multiple Z-shaped scrapers 12 rotates and scrapes synchronously around the periphery of the filling plug 8 to remove the stains adhering to the periphery of the filling plug 8. At the same time, the adsorption pump 32 and the manifold rod 33 cooperate with the main through groove 30, and the scraped stains are adsorbed into the sewage collection box 34 through the adsorption grooves 31 for collection, thus realizing the automatic cleaning of the stains on the periphery of the filling plug 8.
[0029] As Figures 2 - 4 、 Figure 9 shown, an extension rod 38 is fixedly connected to the top of the transmission rack 18. Six negative pressure piston boxes 39 are uniformly and fixedly connected to one end of the filling machine case 1. One end of the extension rod 38 is fixedly connected with a piston rod 40. One end of the piston rod 40 is slidably connected inside the negative pressure piston box 39. The bottom of the negative pressure piston box 39 is fixedly connected with a negative pressure connecting pipe 41 communicating with the drainage pipe 11.
[0030] During use, when the adjustment mechanism drives the lifting platform 6 to start, driving the filling plug 8 to disengage from the inside of the filling barrel 4 along the length direction of the lifting slide rod 5, the lifting platform 6 drives the transmission rack 18 to push the extension rod 38 to slide along the length direction of the lifting slide rod 5. At the same time, the extension rod 38 drives the piston rod 40 to move up and down along the length direction of the negative pressure piston box 39. The piston rod 40 sucks the residual liquid fertilizer inside the drainage pipe 11 into the inner bottom of the negative pressure piston box 39 through the negative pressure connecting pipe 41 for storage. This process makes the inside of the filling plug 8 in a negative pressure state, effectively reducing the situation that the liquid fertilizer inside the drainage pipe 11 drips onto the surface of the conveyor belt 3 through the filling plug 8, thereby significantly improving the practicality of the device.
[0031] As Figure 2 and Figure 3As shown, a pair of ejector slide bars 42 are symmetrically slidably inserted inside the filling machine case 1, one end of the two ejector slide bars 42 is fixedly connected to a groove positioning plate 43 adapted to the filling barrel 4, one end of the filling machine case 1 is fixedly connected to 44, the output end of 44 is fixedly connected to the groove positioning plate 43, and the inner side of the filling machine case 1 is fixedly connected to a second electric push rod L-shaped contact plate 45 adapted to the filling barrel 4.
[0032] When in use, when the device conveyor belt 3 is started to transport the six component filling barrels 4 to the bottom of the filling plug 8, the slider groove positioning plate 43 is pushed by the starting mechanism 44 to move along the length direction of the guide rail ejection slide rod 42, and the six component filling barrels 4 on the top of the device conveyor belt 3 are pushed to move in the direction of the second electric push rod L-shaped contact plate 45. At the same time, the second electric push rod L-shaped contact plate 45 cooperates to form a contact clamp on the component filling barrel 4, so as to adjust the installation position of the component filling barrel 4 and ensure that the input port of the component filling barrel 4 is accurately aligned with the filling plug 8.
[0033] The working principle of a six-head barrel automatic filling machine provided by the present invention is as follows: First, set the working cycle and sleep time of the sensor component. When the preset time is reached, the first electric push rod 15 of the starting mechanism will push the lifting gear 16 to move downward along the length direction of the lifting slide bar 5, while ensuring that the lifting gear 16 is synchronously meshed with the moving rack 13 and the fixed rack 14. During the movement, the lifting gear 16 not only moves along the length direction of the fixed rack 14, but also rotates, continues to mesh with the moving rack 13, and pushes the lifting platform 6 to move along the length direction of the lifting slide bar 5, thereby driving the hinge block 7 and the filling plug 8 to move along the length direction of the lifting slide bar 5; Subsequently, when the lifting platform 6 drives the hinge block 7 to move upward along the length direction of the lifting slide bar 5 for another distance, the lifting platform 6 pushes the transmission rack 18 to move upward along the length direction of the guide slide bar 17, and makes the lower contact block 20 contact the upper contact block 21, causing the lower contact block 20 to drive the transmission rack 18 to mesh with the transmission gear 19. This squeezes the return spring 22 to produce a contraction deformation, accumulating elastic potential energy, and at the same time the transmission gear 19 drives the hinge block 7 and the filling plug 8 to rotate upward around the hinge axis, thereby making the filling plug 8 fit closely with one end of the Z-shaped scraper 12; In addition, during the meshing process of the driving transmission rack 18 and the transmission gear 19, when the transmission gear 19 drives the hinge block 7 to rotate upward by 90°, the hinge block 7 will drive the arc-shaped light-shielding plate 37 to shield one end of the photoelectric switch 36 around the hinge axis, thereby triggering the photoelectric switch 36, and controlling the cleaning motor 26 to drive the worm 25 to start rotating through the control panel 35. At the same time, the worm 25 is engaged with the worm gear 24, and then drives the worm gear 24 to rotate the Z-shaped scraper 12. By the synergistic effect of the synchronous belt 28 and the synchronous pulley 27, one end of multiple Z-shaped scrapers 12 rotates and scrapes synchronously around the periphery of the filling plug 8 to remove the stains adhering to the periphery of the filling plug 8. At the same time, the adsorption pump 32 cooperates with the manifold 33 and the main through groove 30 to adsorb the scraped stains into the inside of the dirt collection box 34 through the adsorption groove 31 for collection, thereby realizing the automatic cleaning of the stains around the filling plug 8; Meanwhile, when the adjusting mechanism drives the lifting platform 6 to start, it will drive the filling plug 8 to disengage from the inside of the filling barrel 4 along the length direction of the lifting slide rod 5. At the same time, the lifting platform 6 drives the transmission rack 18 to push the extension rod 38 to slide along the length direction of the lifting slide rod 5. Then, the extension rod 38 drives the piston rod 40 to move up and down along the length direction of the negative pressure piston box 39, and the piston rod 40 sucks the residual liquid fertilizer inside the drainage pipe 11 into the inner bottom of the negative pressure piston box 39 through the negative pressure connecting pipe 41 for storage. This process creates a negative pressure state inside the filling plug 8, effectively reducing the situation where the liquid fertilizer inside the drainage pipe 11 drips onto the surface of the conveyor belt 3 through the filling plug 8.
