DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0020] Please refer to Figures 1-10 The present application provides a cleaning device for a filling machine and a use method, which comprises a paste filling machine 1, a feed bin 2 and a cleaning mechanism. The feed bin 2 is fixed at the feed inlet of the paste filling machine 1, and the cleaning mechanism is arranged on one side of the feed bin 2. The cleaning mechanism comprises a mounting frame 3, and a drive assembly 4 is arranged on the mounting frame 3. The drive end of the drive assembly 4 is connected with a rotating shaft 5, and the rotating shaft 5 is sleeved with an outer movable frame 51. The outer movable frame 51 is arranged as a hollow boss structure, and a window one 511 penetrating from top to bottom is formed in the surface of the outer movable frame 51. The outer diameter of the outer movable frame 51 is matched with the inner wall of the feed bin 2. An inner support body 52 is arranged in the inner part of the outer movable frame 51, and the inner support body 52 is arranged as a solid body matched with the hollow structure of the outer movable frame 51. The inner support body 52 is provided with window twos 521 of the same specification corresponding to each window one 511. The inner support body 52 is provided with a connecting sleeve 522 matched with the rotating shaft 5. An electromagnetic module 512 is arranged on the inner surface of the outer movable frame 51, and an adsorption module 523 is arranged on the outer surface of the inner support body 52 corresponding to the electromagnetic module 512.

[0021] Based on the above structure, the following supplementary explanations are as follows: Figures 3-5As shown, the friction between the outer movable frame 51 and the inner wall of the feeding bin 2 is greater than the friction between the outer movable frame 51 and the inner support body 52, and the inner support body 52 is connected to the rotating shaft 5. In one case, the window one 511 and the window two 521 are in a coinciding state, and the outer movable frame 51 is in communication with the upper and lower parts of the inner support body 52. When the electromagnetic module 512 is powered on, the adsorption module 523 is closely attached to the electromagnetic module 512, the outer movable frame 51 and the inner support body 52 are connected to form a whole, and the outer movable frame 51 moves with the inner support body 52. In another case, the electromagnetic module 512 is powered off, the outer movable frame 51 is separated from the inner support body 52, and when the inner support body 52 rotates, the outer movable frame 51 is relatively stationary due to the resistance of the inner wall of the feeding bin 2. When the window one 511 and the window two 521 are staggered with each other, the outer movable frame 51 is not in communication with the upper and lower parts of the inner support body 52. At this time, when the electromagnetic module 512 is powered on, the surface of the connecting sleeve 522 is adsorbed and connected to the inner wall of the outer movable frame 51, and the outer movable frame 51 is connected and fixed with the inner support body 52.

[0022] As shown in Figure 2 , Figure 6 , the feeding bin 2 includes a cylindrical barrel 21 and a conical barrel 22, the conical barrel 22 is used to connect the cylindrical barrel 21 and the paste filling machine 1, the outer movable frame 51 is matched with the inner wall of the cylindrical barrel 21, the bottom end of the rotating shaft 5 is provided with a plurality of scrapers 53, the scrapers 53 are matched with the inner wall of the conical barrel 22, the scrapers 53 are connected with telescopic rods 54, springs 55 are connected between the telescopic rods 54 and the rotating shaft 5, and sleeve rods 56 are connected to the rotating shaft 5 and matched with the telescopic rods 54.

[0023] In actual operation, the scraper 53 can be self-adaptively adjusted according to the change of the inner diameter of the conical barrel 22. When the scraper 53 moves downward, the inner diameter of the conical barrel 22 gradually decreases, and the scraper 53 is retracted into the sleeve rod 56 by compressing the spring 55 through the telescopic rod 54. When the scraper 53 moves upward, the inner diameter of the conical barrel 22 gradually increases, and the scraper 53 gradually extends out of the sleeve rod 56 under the elastic force of the spring 55.

[0024] As shown in Figure 2 , the driving assembly 4 includes a longitudinal screw 41, a motor one 42 and a lifting platform 43. The longitudinal screw 41 is rotationally arranged on the mounting frame 3, the motor one 42 is fixed on the mounting frame 3 and connected with the longitudinal screw 41, the lifting platform 43 is arranged on the longitudinal screw 41, a plurality of guide rods one 44 are arranged on the lifting platform 43, the motor two 45 is fixed on the lifting platform 43 and connected with the rotating shaft 5 through a belt pulley.

[0025] In actual operation, the motor one 42 controls the rotation of the longitudinal screw 41, so that the lifting platform 43 moves up and down along the guide rod one 44, thereby controlling the up and down movement of the rotating shaft 5. The motor one 42 controls the rotation of the rotating shaft 5 through the belt pulley.

[0026] As shown in Figure 7 , the mounting frame 3 is provided with a spraying assembly 6, which is arranged in a semicircular structure on the upper side of the feeding bin 2.

[0027] The spraying assembly 6 comprises a rotating plate 61 rotatably arranged on the mounting frame 3, a motor 62 connected to the rotating plate 61, an arc plate 63 connected to the rotating plate 61, a plurality of nozzle groups 64 arranged at intervals on the lower side of the arc plate 63, and a visual detection module arranged on the rotating plate 61.

[0028] Further, as shown in Figure 9 , the nozzle group 64 comprises two connecting plates 641, a rotating rod 642 rotatably arranged on the connecting plates 641, a hinged plate 643 arranged on the rotating rod 642, torsion springs 644 connected between the hinged plate 643 and the connecting plates 641 on both sides, and a nozzle one 645 arranged on the inward end of the hinged plate 643.

[0029] Further, as shown in Figure 8 , the arc plate 63 is provided with an arc-shaped slot, a cover plate 65 is fixed on the arc-shaped slot, a cylinder one 66 is fixed on the cover plate 65, the driving end of the cylinder one 66 extends out of the arc-shaped slot to the lower side of the arc plate 63, a pressing plate 67 is connected to the driving end of the cylinder one 66, the pressing plate 67 is located below the outward end of each hinged plate 643, a plurality of guide rods two 68 are arranged on the pressing plate 67, and the guide rods two 68 are in sliding cooperation with the cover plate 65.

[0030] It should be noted that: in the initial state, the hinged plate 643 is upwardly tilted by the torsion springs 644 at the inward end, at this time the nozzle one 645 is connected with a liquid input pipeline, and the nozzle one 645 has a nozzle direction towards the inside; when the cylinder one 66 controls the pressing plate 67 to move upward, the pressing plate 67 presses the hinged plate 643, the hinged plate 643 drives the rotating rod 642 to rotate downward, and the nozzle direction of the nozzle one 645 changes from the inside to the outside; when the cylinder one 66 controls the pressing plate 67 to move downward, the pressing plate 67 releases the pressure on the hinged plate 643, and the hinged plate 643 is reset by the torsion springs 644.

[0031] In an embodiment, the rotating rod 642 extends out of the connecting plates 641 at both ends and is sleeved with a gear one 646, the gear one 646 is cooperatively provided with a gear two 647, the gear two 647 is connected with a driving rod 648, the driving rod 648 is rotatably arranged on the connecting plates 641, and a nozzle two 649 is arranged on the driving rod 648.

[0032] In the initial state, the nozzle direction of the nozzle two 649 is towards the outside; when the rotating rod 642 drives the gear one 646 to rotate forward, the gear two 647 synchronously drives the driving rod 648 to rotate reversely, the nozzle direction of the nozzle two 649 changes from the outside to the inside, and the nozzle one 645 and the nozzle two 649 are staggered.

[0033] As Figure 10 shown, the cream filling machine 1 comprises a steering cavity 11, which is provided with three openings and connected with an extrusion port 12, a feeding bin 2 and a piston cylinder 13 respectively. A three-way valve 14 is arranged in the steering cavity 11 and extends out of the steering cavity 11 on one side and is connected with a cylinder two 15.

[0034] In actual operation, the three-way valve 14 is provided with three openings, which are communicated with each other when corresponding to the three openings of the steering cavity 11. At this time, the piston cylinder 13 sucks the material in the feeding bin 2 through suction movement, and then the three-way valve 14 is controlled to rotate by the cylinder two 15 so that one of the openings faces downward. At this time, the passage between the steering cavity 11 and the feeding bin 2 is closed, and the passages between the steering cavity 11 and the extrusion port 12 and the piston cylinder 13 are formed. At this time, the piston cylinder 13 pushes the material to the extrusion port 12, and finally the material is discharged through the extrusion port 12.

[0035] Preferably, the cleaning mechanism further comprises a detection box 7 for detecting the state of the cleaning water. The detection box 7 is provided with a filter layer 71 inside, which is connected with a pressure sensor for detecting whether large-volume impurities are mixed in the cleaning water. The lower side of the filter layer 71 is provided with a turbidity meter 72 for detecting the turbidity of the cleaning water.

[0036] It should be noted that the detection box 7 is provided with a pump body 8 on the pipeline connected with the feeding bin 2 or the extrusion port 12 when used for recycling and detecting the cleaning water.

[0037] The specific implementation is as follows: In the non-cleaning mode, the cleaning mechanism can be used for stirring the material in the feeding bin 2. At this time, the window one 511 and the window two 521 are in the overlapping state, and the outer movable frame 51 and the inner support 52 are connected with each other and communicated with each other. The rotation of the shaft 5 drives the outer movable frame 51 and the inner support 52 to rotate, and the driving assembly 4 controls the shaft 5 to reciprocate up and down at a certain distance, and the material flows up and down through the window one 511 and the window two 521.

[0038] In the cleaning mode, before the end of the material extrusion, the rotating shaft 5 controls the outer movable frame 51 and the inner support body 52 to move up to the upper side of the feeding bin 2 and remain in a rotating state, allowing the material on the surface of the outer movable frame 51 to enter the lower space through the window one 511 and the window two 521. The visual detection module detects the coverage state of the material on the surface of the outer movable frame 51, and increases the instantaneous acceleration by intermittently increasing the rotating speed of the rotating shaft 5, so that the material on the surface of the outer movable frame 51 is more easily dropped. When the attached material is reduced to a certain extent, the rotating shaft 5 stops rotating, the electromagnetic module 512 is powered off, the outer movable frame 51 is separated from the inner support body 52, the rotating shaft 5 drives the inner support body 52 to rotate to the state that the window one 511 and the window two 521 are staggered, and the outer movable frame 51 is separated into upper and lower parts. The rotating shaft 5 controls the outer movable frame 51 to move down to press the remaining material out of the feeding bin 2. In the process of moving down, the edge of the outer movable frame 51 scrapes off the material on the inner wall of the feeding bin 2, improving the completeness of the material out of the feeding bin 2 and also performing primary cleaning on the inner wall of the feeding bin 2. When the outer movable frame 51 moves down to the bottom, it is located between the barrel 21 and the cone barrel 22, the material on the inner wall of the barrel 21 has been scraped off, and the scraper 53 is located in the cone barrel 22. The rotating shaft 5 controls the outer movable frame 51 to move up in place, deflect by a certain angle, and then move down, so that the scraper 53 can scrape off the surface of the cone barrel 22 in a circular manner.

[0039] When the paste filling machine 1 cannot extrude the material, the next cleaning process is entered. The rotating shaft 5 controls the outer movable frame 51 to rotate, so that the window one 511 and the window two 521 are coincided, the outer movable frame 51 is connected with the inner support body 52, and the rotating shaft 5 pulls the outer movable frame 51 to move up to the lower side of the spraying assembly 6. In this process, the outer movable frame 51 will scrape the inner wall of the barrel 21 again, and the scraped material will accumulate on the surface of the outer movable frame 51. The nozzle group 64 is started to spray cleaning water on the surface of the outer movable frame 51. The rotating shaft 5 controls the outer movable frame 51 to rotate slowly, so that the surface material is washed by the cleaning water to the lower space of the outer movable frame 51. The visual detection module confirms the surface state of the outer movable frame 51 and the gap surface state between the window one 511 and the window two 521, to ensure that there is no visible material attached to the surface. After the upper surface of the outer movable frame 51 is cleaned, the window one 511 and the window two 521 are switched to the staggered state. The rotating shaft 5 moves down and remains in a rotating state, so that the lower cleaning water can fully contact the inner wall of the feeding bin 2, the lower surface of the outer movable frame 51, and the scraper 53. After a period of time, the cleaning water is pumped into the detection box 7 for detection by the pump body 8, to determine the internal state of the cleaning water and thus confirm whether the cleaning is complete. The above process is repeated until the cleaning water reaches the standard.

[0040] Further, different volumes of material will be mixed in the cleaning water during a cleaning cycle. The large-volume block material is screened out by the filter layer 71. Whether there is material attached to the upper side of the filter layer 71 is determined according to the pressure value detected by the pressure sensor. Once the pressure sensor determines that there is large-volume material on the upper side of the filter layer 71, it is determined that the cleaning is not complete, and the next cleaning cycle is started.

[0041] Further, when no large volume of material is detected on the upper side of the filter layer 71 during a cleaning cycle, the turbidity of the cleaning water is detected by the turbidity meter 72 until the cleaning criteria are met.

A filter layer (71) is provided inside the detection box (7). The filter layer (71) is connected to a pressure sensor for detecting whether large-volume impurities are contained in the cleaning water. A turbidity meter (72) is provided on the lower side of the filter layer (71) for detecting the turbidity of the cleaning water.

9. A method for using a cleaning device for a filling machine, applicable to the cleaning device for a filling machine according to claim 8, characterized in that: Before the extrusion of the material is completed, the rotating shaft (5) controls the outer movable frame (51) and the inner support body (52) to move upward to the upper side of the feed bin (2) and maintain the rotating state, so that the material on the surface of the outer movable frame (51) enters the lower space along the window 1 (511) and the window 2 (521). The visual detection module detects the material covering state on the surface of the outer movable frame (51) and increases the instantaneous acceleration by intermittently increasing the rotation speed of the rotating shaft (5), so that the material on the surface of the outer movable frame (51) is more likely to fall off; When the attached material is reduced to a certain extent, the rotating shaft (5) stops rotating, and the window 1 (511) and the window 2 (521) are switched to a staggered state. The rotating shaft (5) controls the outer movable frame (51) to move downward, forcing the remaining material to be discharged. During the downward movement, the edge of the outer movable frame (51) scrapes off the material on the inner wall of the feed bin (2). When the outer movable frame (51) moves down to the bottom, it is located between the round barrel (21) and the conical barrel (22), and the material on the inner wall of the round barrel (21) has been scraped off. The scraper (53) is located inside the conical barrel (22), and the rotating shaft (5) controls the in-situ upward deflection to a certain angle and then moves down, so that the scraper (53) can scrape the surface of the conical barrel (22) in a circular manner.

10. The method for using the cleaning device for a filling machine according to claim 9, characterized in that: When the paste filling machine (1) is unable to squeeze out the material, it enters the next cleaning process; Window 1 (511) and window 2 (521) are switched to a superimposed state, the outer movable frame (51) is connected to the inner support body (52), and the rotating shaft (5) pulls the outer movable frame (51) upward to the lower side of the spray assembly (6); The scraped materials are accumulated on the surface of the outer movable frame (51), the nozzle group (64) is started, and cleaning water is sprayed on the surface of the outer movable frame (51), and the rotating shaft (5) controls the outer movable frame (51) to rotate slowly, so that the surface materials are washed into the lower space of the outer movable frame (51) by the cleaning water; The visual inspection module confirms the surface condition of the external movable frame (51) and the surface condition of the gap between window 1 (511) and window 2 (521) to ensure that there is no material attached to the surface visible to the naked eye; After the upper surface of the outer movable frame (51) is cleaned, the window one (511) and the window two (521) are switched to a staggered state; The rotating shaft (5) moves downward and keeps rotating, so that the lower layer of cleaning water can fully contact the inner wall of the feed bin (2), the lower surface of the outer movable frame (51) and the scraper (53); After a period of time, the cleaning water is pumped into the detection box (7) through the pump body (8) for detection to determine the internal state of the cleaning water and thus confirm whether it is clean; Repeat the above steps until the cleaning water reaches the standard.
