Description

Technical Field

[0001] The invention relates to the technical field of tank cleaning, and in particular to a cleaning device for dairy product processing equipment. Background Art

[0002] Dairy products, also known as dairy products, milk foods or dairy foods, are foods processed with milk as the basic raw material. Dairy product processing is the process of using milk as the basic raw material to process various delicious dairy products through a series of processes. In the process of dairy product processing, different processing equipment is required, among which the milk tank used to store milk is particularly important, because the milk tank can not only store the milk, but also prevent the invasion of external bacteria, which plays a key role in the quality preservation of the milk. When the milk in the milk tank is discharged, due to long-term storage, a certain amount of milk residue will be more or less adhered to the inner wall of the milk tank. In order not to affect the subsequent storage work, after the original milk is discharged, the milk tank needs to be cleaned in time to prevent the milk residue from solidifying and becoming scale. The existing patent with the announcement number CN117443887B in my country discloses a cleaning and disinfecting device for the inner wall of a dairy product storage tank to solve the problem of low manual cleaning efficiency, but the above patent also has the following defects:

[0003] First, as a storage device, the main function of the milk tank is to store milk, and the above-mentioned equipment is fixed in the milk tank. Since the equipment itself occupies a part of the space of the milk tank, the amount of milk stored in the milk tank will be greatly reduced, and the milk tank needs to maintain a sterile environment, and the cleaning equipment immersed in the milk tank will cause the milk in the milk tank to deteriorate due to bacterial contamination;

[0004] Secondly, the milk residue attached to the inner wall of the milk tank is a thick substance. When the scraper in the above patent revolves, the scraper is in contact with the inner wall of the milk tank only through a plurality of scraping teeth, so the contact area between the scraper and the inner wall of the milk tank is small. Therefore, the plurality of scraping teeth on the scraper will only take away a part of the milk residue, and it is difficult to completely scrape off the milk residue. At this time, the milk residue attached to the inner wall of the milk tank will form scratches.

[0005] Thirdly, when the scraper scrapes the milk residue on the inner wall of the milk tank, the scraped milk residue will adhere to the scraper. Then, as the scraper continues to revolve, the milk residue on the scraper will accumulate more and more, eventually resulting in a reduction in the scraping efficiency of the scraper. In addition, the milk residue attached to the scraper will adhere to the inner wall of the milk tank again. Therefore, it is necessary to provide a cleaning device for dairy product processing equipment to solve the above problems. Summary of the invention

During scraping, the two strip scraping rods in the scraping mechanism will fit the inner wall of the milk tank and slide up and down reciprocatingly. The contact area between the strip scraping rods and the inner wall of the milk tank is large, which is convenient for scraping off the milk residue on the inner wall of the milk tank. In addition, the milk residue that has solidified and turned into dirt can also be scraped off by the up and down sliding of the strip scraping rods, which greatly improves the cleaning efficiency of the milk tank.

[0020] Thirdly, the lifting seat of the device has a descending stroke set in advance through a program, and the lifting seat descends in stages, that is, the lifting seat will stop descending after descending a fixed stroke, and continue to descend after stopping for a period of time, and repeat this cycle until the scraping and washing component descends to the bottom of the milk tank. Before the lifting seat starts the next stage of descent, the scraper rod cleaning mechanism will clean the strip scraper rod, thereby improving the scraping efficiency of the strip scraper rod itself and preventing the milk residue on the strip scraper rod from adhering to the inner wall of the milk tank again.

[0041] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] refer to Figures 1 to 19 The cleaning device for dairy product processing equipment shown in the figure comprises a lifting seat 1, a rotating table 2 and a scraping and washing assembly, wherein the rotating table 2 is arranged on the lifting seat 1, a circular mounting seat is fixedly arranged on the rotating table 2, and the scraping and washing assembly is arranged on the mounting seat, and the scraping and washing assembly comprises a telescopic mechanism, two groups of scraping mechanisms and two groups of liquid spraying mechanisms, and the telescopic mechanism comprises two groups of telescopic arms 3 (such as Figure 4 As shown in the figure, each set of scraping mechanisms includes a transmission member and two strip scraping rods 4 sliding on the telescopic arm 3 in the vertical direction, each strip scraping rod 4 is vertical, a No. 1 motor 5 is provided on the mounting seat, and the transmission member drives the No. 1 motor 5 to connect with the corresponding two strip scraping rods 4, the spray mechanism includes a spray pipe 6 vertically arranged between the two strip scraping rods 4, and each telescopic arm 3 is provided with a scraping rod cleaning mechanism, which includes a strip slide 7, a delay member and two spray heads 8 (as shown in the figure). Figure 4As shown in the figure, the strip slide 7 is arranged above the telescopic arm 3, and the strip slide 7 is parallel to the telescopic arm 3, each nozzle 8 is arranged on one end of the strip slide 7, the two nozzles 8 correspond to the two strip scraper rods 4 respectively, and each nozzle 8 is in an inclined state. The delay part includes a support plate 9 and a limit pin 10. The support plate 9 is vertically connected to the strip slide 7, and the limit pin 10 is horizontally connected to the telescopic arm 3. The support plate 9 is provided with a strip limit groove 11 for the limit pin 10 to pass through.

[0043] In the initial state, the two sets of telescopic arms 3 are in a retracted state. When the milk tank needs to be cleaned, the rotating platform 2 and the scraping and washing assembly are lowered into the mouth of the milk tank through the lifting seat 1. Since the milk tank has a certain height, the lifting seat 1 is pre-programmed to set the descending stroke, and the lifting seat 1 descends in stages, that is, the lifting seat 1 stops descending after descending a fixed stroke, and continues to descend after stopping for a period of time, and repeats this cycle until the scraping and washing assembly descends to the bottom of the milk tank;

[0044] When the lifting seat 1 stops descending, the two sets of telescopic arms 3 extend outward synchronously until each strip scraper 4 fits against the inner wall of the milk tank. During this process, the limit pin 10 provided on the telescopic arm 3 will drive the entire strip slide 7 to translate by abutting against one end of the strip limit groove 11, that is, the strip slide 7 will extend outward along with the telescopic arm 3. When the telescopic arm 3 is extended, the rotating table 2 starts to rotate, and the rotating table 2 will drive the entire scraping and washing assembly to rotate slowly through the mounting seat. During this process, the spray pipe 6 provided between the two strip scrapers 4 will spray the inner wall of the milk tank. Sprinkle cleaning liquid, at the same time, the first motor 5 will drive the corresponding two strip scraper rods 4 to slide reciprocatingly up and down through the transmission parts, and the milk residue attached to the inner wall of the milk tank can be scraped off better through the up and down sliding of the strip scraper rods 4, so as to improve the cleaning efficiency. After the rotating table 2 rotates one circle, the rotating table 2 stops rotating. At this time, the inner wall of the milk tank corresponding to the strip scraper rods 4 will be scraped clean, and there may be milk residue attached to the strip scraper rods 4, so the scraper rod cleaning mechanism will clean the strip scraper rods 4 thereafter. The specific cleaning process is as follows: when the rotating table 2 stops rotating, The two groups of telescopic arms 3 are synchronously extended and retracted inward for a certain distance, and the limit pins 10 connected to the telescopic arms 3 will slide in the corresponding strip limit grooves 11. At this time, the retraction stroke of the telescopic arms 3 is controlled to ensure that the limit pins 10 will not conflict with one end of the strip limit grooves 11. Then, during the retraction of the telescopic arms 3, the current strip slide 7 will not retract with the telescopic arms 3. When the telescopic arms 3 stop retracting, the two nozzles 8 provided on one end of the strip slide 7 will be exposed to the outside. Thereafter, the two inclined nozzles 8 are used to spray the two strip scraper rods 4 on the telescopic arms 3. After the strip scraper 4 is rinsed clean, the two sets of telescopic arms 3 will extend outward to their original state again, and then the lifting seat 1 will start the next stage of descent. When the lifting seat 1 stops descending, the scraping and washing assembly will repeat the above-mentioned working process, and before the lifting seat 1 starts the next stage of descent, the scraper cleaning mechanism will clean the strip scraper 4, and finally the entire inner wall of the milk tank will be cleaned by the scraping and washing assembly, and in the process of cleaning the inner wall of the milk tank, the strip scraper 4 will be self-cleaned by the scraper cleaning mechanism, so as to improve the scraping efficiency of the strip scraper 4 itself.

[0045] In order to show how the two sets of telescopic arms 3 are installed, the following features are set:

[0046] The mounting base includes a first cylinder 12 and a second cylinder 13. The first cylinder 12 is vertical, and the top of the first cylinder 12 is fixedly connected to the rotating table 2. The second cylinder 13 is vertical, and the top of the second cylinder 13 is coaxially fixedly connected to the bottom of the first cylinder 12. A horizontal circular support plate 14 (such as Figure 7 As shown in FIG. 1 , a horizontal circular support plate 15 is fixedly formed in the upper end of the second cylinder 13, and two strip-shaped fixing seats 16 are fixedly provided on the circular support plate 14, and each strip-shaped fixing seat 16 has a strip-shaped slide groove 17 (as shown in FIG. 1 ). Fig. 9 As shown in FIG. 1 ), the length direction of each strip chute 17 is consistent with the radial direction of the circular support plate 14, and each telescopic arm 3 slides in the corresponding strip chute 17. The outer wall of the second cylinder 13 is provided with two openings 18 (as shown in FIG. 1 ). Fig.14 As shown in the figure, the two groups of telescopic arms 3 respectively pass through the two through openings 18, and a telescopic driving member for driving the two groups of telescopic arms 3 to synchronously extend and retract is provided in the second cylinder 13.

[0047] Each set of telescopic arms 3 slides in the corresponding strip-shaped fixed seat 16 through the strip-shaped slide groove 17. When the telescopic driving member is started, the two sets of telescopic arms 3 will extend outward through the two through openings 18 respectively. Through the extension and retraction of the telescopic arms 3, the entire scraping and washing assembly can be suitable for milk cans with different diameters. When the scraping and washing assembly is extended into the milk can through the lifting seat 1, the two sets of telescopic arms 3 are in a retracted state, thereby preventing the telescopic arms 3 from colliding with the narrower opening of the milk can.

[0048] In order to show the specific structure of the telescopic drive, the following features are set:

[0049] The telescopic drive member includes a turntable 19 and a second motor 20, which is disposed in the first cylinder 12 (eg Figure 4 As shown), the second motor 20 is vertically fixed to the top of the circular support plate 15, the turntable 19 is horizontally rotated in the second cylinder 13, and the turntable 19 is coaxial with the second cylinder 13, the output end of the second motor 20 is coaxially fixed downward with the turntable 19, two strip-shaped fixing seats 16 are located between the turntable 19 and the circular support plate 14, and the turntable 19 is provided with two arc-shaped through grooves 21 (as shown in FIG. Figure 8 As shown in the figure, the two arc-shaped through grooves 21 are centrally symmetrical about the center of the turntable 19, and a vertical pin 22 is fixed on the top of each set of telescopic arms 3. The upper ends of the two vertical pins 22 respectively pass through the two arc-shaped through grooves 21 upward, and a strip-shaped avoidance groove 23 for the vertical pin 22 to slide is opened on the top of each strip-shaped fixing seat 16.

[0050] The second motor 20 is used to drive the turntable 19 to rotate. When the turntable 19 rotates, the two arc-shaped slots 21 on the turntable 19 will rotate. During this process, each vertical pin 22 will slide in the corresponding arc-shaped slot 21, and the vertical pin 22 will be driven to move through the interference of the arc-shaped slot 21. Since the vertical pin 22 is connected to the telescopic arm 3, and the telescopic arm 3 is limited by the strip slide groove 17, each group of telescopic arms 3 will be telescoped along the radial direction of the circular support plate 14 after the turntable 19 rotates.

[0051] In order to show how each strip scraper bar 4 is connected to the telescopic arm 3, the following features are set:

[0052] A connecting frame is provided on the outer end of each set of telescopic arms 3, and each connecting frame includes two symmetrical strip shells 24 (such as Fig.11 As shown in the figure, each strip shell 24 is vertical, and a connecting plate 25 connecting the two strip shells 24 is provided at the bottom. The outer end of each group of telescopic arms 3 is fixed between the two strip shells 24, and a vertical strip slider 26 is provided in each strip shell 24. The lower end of the strip slider 26 passes downward through the connecting plate 25, and the two strip scrapers 4 on each group of telescopic arms 3 are respectively fixedly connected to the two strip sliders 26.

[0053] The strip slider 26 is used to limit the displacement direction of the strip scraper 4 to ensure that the strip scraper 4 can only slide up and down in the vertical direction. Since each set of telescopic arms 3 is fixedly connected to two strip shells 24, when the telescopic arms 3 are extended or retracted, each strip scraper 4 will be driven to extend or retract. Finally, the strip scraper 4 will fit on the inner wall of the milk tank and scrape off the milk residue by sliding up and down.

[0054] In order to show the specific structure of the transmission parts, the following features are set:

[0055] The bottom of each connecting plate 25 is formed with two vertically downward upright plates 27, and the two upright plates 27 correspond to the two strip shells 24 respectively. The transmission member includes a lifting drive member and a rotating drive member. The lifting drive member includes a rotating shaft 28 and two cams 29. The rotating shaft 28 rotates horizontally between the two upright plates 27. Each cam 29 is fixed on the rotating shaft 28 (such as Fig.17 As shown in FIG. 1 ), the lower end of each strip-shaped slider 26 is located between the corresponding cam 29 and the vertical plate 27, and a horizontal fixing pin 30 that contacts the cam 29 is formed on the side wall of the lower end of each strip-shaped slider 26. The lower end of each strip-shaped slider 26 is provided with a strip-shaped through groove 31 (as shown in FIG. 1 ) for the rotating shaft 28 to pass through. Fig.19 As shown in the figure, the length direction of the strip through groove 31 is parallel to the sliding direction of the strip slider 26, and each strip shell 24 is provided with an elastic member for resetting the strip slider 26. The rotating driving member is provided between the No. 1 motor 5 and the rotating shaft 28, and the rotating driving member is used to drive the rotating shaft 28 to rotate.

[0056] When the No. 1 motor 5 is driven, the No. 1 motor 5 will drive the rotating shaft 28 to rotate through the rotating driving member. When the rotating shaft 28 rotates, the rotating shaft 28 will synchronously drive the two cams 29 to rotate, so that each cam 29 will conflict with the corresponding fixing pin 30 during the rotation process, so that the fixing pin 30 will be driven by the cam 29 to move. Since the fixing pin 30 is connected to the strip slider 26, and the strip slider 26 slides in the corresponding strip shell 24 along the vertical direction, the strip slider 26 will be driven by the cam 29 to slide up and down. When the cam 29 rotates to the point where the wave crest on it conflicts with the fixing pin 30, the strip slider 26 will be driven to rise. At this time, the strip slider 26 The strip slider 26 will compress the elastic member in the strip shell 24 upward, causing the elastic member to generate elastic force. When the cam 29 rotates until the wave crest thereon is away from the fixing pin 30, the strip slider 26 will be driven down by the elastic force of the elastic member, and this cycle will be repeated. The strip through groove 31 provided on the lower end of the strip slider 26 is used to avoid the rotating shaft 28. When the cam 29 is installed, the wave crests of the two cams 29 are in opposite directions. Therefore, when the rotating shaft 28 continues to rotate, one of the strip scraper rods 4 will rise, while the other strip scraper rod 4 will fall. Finally, the two strip scraper rods 4 will scrape off the milk residue attached to the inner wall of the milk tank by reciprocating up and down sliding.

[0057] In order to show the specific structure of the elastic part, the following features are set:

[0058] The top of each strip shell 24 is an open structure, and a horizontal cover plate 32 is fixedly provided on the top of each strip shell 24. The elastic member includes a plurality of springs 33, and each spring 33 is vertically arranged in the corresponding strip shell 24, and the two ends of each spring 33 are respectively in contact with the cover plate 32 and the top of the strip slider 26.

[0059] When the cam 29 rotates until the wave crest thereon contacts with the fixed pin 30, the strip slider 26 will be driven to rise, and at this time the strip slider 26 will compress the corresponding plurality of springs 33 upward, so that the springs 33 generate elastic force, and when the cam 29 rotates until the wave crest thereon is away from the fixed pin 30, the fixed pin 30 loses the contact with the wave crest of the cam 29, so the compressed spring 33 will drive the strip slider 26 to descend through the elastic force, and this cycle will be repeated, and the upper end of each strip slider 26 will slide up and down in the corresponding strip shell 24, and the lower end of each strip slider 26 will drive the corresponding strip scraper rod 4 to slide up and down on the inner wall of the milk tank.

[0060] In order to show the specific structure of the rotating drive, the following features are set:

[0061] Each rotary drive member includes a worm wheel 34, a worm 35, a telescopic rotating rod and a bevel gear set. The worm wheel 34 is coaxially fixedly connected to the corresponding rotating shaft 28, and the worm 35 (such as Fig.11As shown in the figure, the worm wheel 34 is vertically connected to the corresponding telescopic arm 3, and the worm wheel 34 is meshed with the worm 35. The telescopic rotating rod includes a rotating tube 36 and a spline shaft 37. The rotating tube 36 is connected to the bottom of the circular support plate 14. The axial direction of the rotating tube 36 is parallel to the sliding direction of the telescopic arm 3. One end of the spline shaft 37 is connected to the corresponding telescopic arm 3. The other end of the spline shaft 37 is inserted into the rotating tube 36. The inner wall of the rotating tube 36 is formed with an inner gear ring 38 (as shown in the figure) that is engaged with the spline shaft 37. Fig.12 As shown in FIG. 1 ), the bevel gear set includes a first bevel gear 39, a second bevel gear 40 and a third bevel gear 41. The first bevel gear 39 is coaxially fixed to the worm 35, the second bevel gear 40 is coaxially fixed to one end of the spline shaft 37, and the first bevel gear 39 is meshed with the second bevel gear 40. The third bevel gear 41 (as shown in FIG. Figure 7 As shown in the figure, the No. 1 motor 5 is coaxially fixedly connected to the other end of the spline shaft 37, and the No. 1 motor 5 is vertically fixed to the bottom of the circular support plate 14. The No. 4 bevel gear 42 is coaxially fixedly connected to the output end of the No. 1 motor 5, and the two No. 3 bevel gears 41 are meshed with the No. 4 bevel gear 42.

[0062] When the No. 1 motor 5 is started, the No. 1 motor 5 will drive the two No. 3 bevel teeth 41 to rotate synchronously through the No. 4 bevel gear 42, so that each No. 3 bevel gear 41 will drive the corresponding rotating tube 36 to rotate. When the rotating tube 36 rotates, the spline shaft 37 will be driven to rotate through the action of the inner gear ring 38, so that the spline shaft 37 will drive the No. 1 bevel gear 39 to rotate through the No. 2 bevel gear 40. After the No. 1 bevel gear 39 rotates, the worm 35 will drive the worm wheel 34 to rotate. Finally, the worm wheel 34 will drive the two cams 29 to rotate through the rotating shaft 28, and thereby drive the two strip scrapers 4 to slide up and down. When the telescopic arm 3 is extended and retracted, since one end of the spline shaft 37 is rotatably connected to the telescopic arm 3, the spline shaft 37 will be extended and retracted in the rotating tube 36. The cooperation between the spline shaft 37 and the rotating tube 36 ensures that the two strip scrapers 4 can always be driven to rotate by the No. 1 motor 5.

[0063] In order to show the specific structure of the spray mechanism, the following features are set:

[0064] A liquid storage tank 43 is fixedly disposed on the top of the circular support plate 15. Each group of liquid spraying mechanisms also includes a liquid infusion hose 44 (such as Fig.16 As shown in FIG. 1 ), the upper end of each liquid spray pipe 6 is connected to the liquid spray pipe 6 by a connecting rod 45 (as shown in FIG. Figure 5 As shown in the figure, the two ends of each liquid spray pipe 6 are connected to the connecting plate 25, and both ends of each liquid spray pipe 6 are closed structures. The outer wall of each liquid spray pipe 6 is provided with a plurality of nozzles 46 equidistantly distributed along its axial direction, and the outer wall of each liquid spray pipe 6 is provided with a water inlet 47. Each infusion hose 44 connects the corresponding water inlet 47 to the liquid storage tank 43, and the top of the liquid storage tank 43 is fixedly provided with a liquid inlet pipe 48 passing through the outside of the No. 1 cylinder 12.

[0065] The cleaning liquid is injected into the liquid storage tank 43 through the liquid inlet pipe 48, and the cleaning liquid is stored in the liquid storage tank 43. In actual use, a No. 1 lifting pump (not shown in the figure) is provided between each infusion hose 44 and the liquid storage tank 43. The cleaning liquid in the liquid storage tank 43 is pumped out by the No. 1 lifting pump, and the cleaning liquid pumped out from the liquid storage tank 43 will enter the spray pipe 6 through the corresponding infusion hose 44, and finally be sprayed onto the inner wall of the milk tank from the several nozzles 46 on the spray pipe 6. When installing the infusion hose 44, the infusion hose 44 needs to pass through the No. 2 cylinder 13, so that the No. 2 cylinder 13 needs to be provided with an avoidance port for the infusion hose 44 to pass through, and the infusion hose 44 needs to have a certain length, so that when the telescopic arm 3 is extended, the infusion hose 44 will not be broken.

[0066] In order to show how the strip carriage 7 is installed, the following features are provided:

[0067] Two lugs 49 are formed on the outer wall of the second cylinder 13. Figure 5 ) respectively correspond to the two telescopic arms 3, each lug 49 is fixed with a strip support 50, and the strip support 50 is provided with a strip guide groove 51 (as shown in Fig.15 As shown in the figure), the length direction of the strip guide groove 51 is parallel to the sliding direction of the telescopic arm 3, and the top of each strip slide 7 is formed with a strip guide block 52 that slides in the strip guide groove 51.

[0068] Through the cooperation between the strip guide block 52 and the strip guide groove 51, the sliding direction of the strip slide 7 is consistent with the sliding direction of the telescopic arm 3. When the telescopic arm 3 begins to extend, the limit pin 10 provided on the telescopic arm 3 will abut one end of the strip limit groove 11, so that the entire strip slide 7 will extend together with the telescopic arm 3. When the telescopic arm 3 begins to retract, the limit pin 10 provided on the telescopic arm 3 will slide in the strip limit groove 11. Thereafter, only when the limit pin 10 abuts against the other end of the strip limit groove 11, the strip slide 7 will retract together with the telescopic arm 3. Therefore, by controlling the retraction stroke of the telescopic arm 3, the two nozzles 8 provided on the strip slide 7 are exposed to the outside, and finally the strip scraper rod 4 is flushed by the nozzle 8.

[0069] In order to show how the two nozzles 8 spray water, the following features are set:

[0070] A three-way connector 53 is provided between the two nozzles 8, and the three-way connector 53 connects the two nozzles 8. A water hose 54 is also connected to the three-way connector 53. A water tank 55 is fixedly provided on the top of the circular support plate 15. One end of each water hose 54 is inserted into the No. 1 cylinder 12 and connected to the water tank 55. A water inlet pipe 56 is formed on the top of the water tank 55 and passes through the No. 1 cylinder 12.

[0071] Clean water is injected into the water tank 55 through the water inlet pipe 56. The water tank 55 is used to store clean water. In actual use, a No. 2 lifting pump (not shown in the figure) is provided between each water supply hose 54 and the water tank 55. When the strip scraper 4 needs to be flushed, the No. 2 lifting pump will pump out the water in the water tank 55. The pumped clean water will enter the three-way connector 53 through the water supply hose 54, and through the diversion effect of the three-way connector 53, the clean water will be sprayed out from the two nozzles 8 respectively. Since the two nozzles 8 correspond to the two strip scrapers 4 respectively, and each nozzle 8 is in an inclined state, the spray from the nozzle 8 will directly act on the corresponding strip scraper 4, thereby finally flushing the strip scraper 4.

[0072] Working principle:

[0073] In the initial state, the two sets of telescopic arms 3 are in a retracted state. When the milk tank needs to be cleaned, the rotating platform 2 and the scraping and washing assembly are lowered into the mouth of the milk tank through the lifting seat 1. Since the milk tank has a certain height, the lifting seat 1 is pre-programmed to set the descending stroke, and the lifting seat 1 descends in stages, that is, the lifting seat 1 stops descending after descending a fixed stroke, and continues to descend after stopping for a period of time, and repeats this cycle until the scraping and washing assembly descends to the bottom of the milk tank;

[0074] When the lifting seat 1 stops descending, the two sets of telescopic arms 3 extend outward synchronously until each strip scraper 4 fits against the inner wall of the milk tank. During this process, the limit pin 10 provided on the telescopic arm 3 will drive the entire strip slide 7 to translate by abutting against one end of the strip limit groove 11, that is, the strip slide 7 will extend outward along with the telescopic arm 3. When the telescopic arm 3 is extended, the rotating table 2 starts to rotate, and the rotating table 2 will drive the entire scraping and washing assembly to rotate slowly through the mounting seat. During this process, the spray pipe 6 provided between the two strip scrapers 4 will spray the inner wall of the milk tank. Sprinkle cleaning liquid, at the same time, the first motor 5 will drive the corresponding two strip scraper rods 4 to slide reciprocatingly up and down through the transmission parts, and the milk residue attached to the inner wall of the milk tank can be scraped off better through the up and down sliding of the strip scraper rods 4, so as to improve the cleaning efficiency. After the rotating table 2 rotates one circle, the rotating table 2 stops rotating. At this time, the inner wall of the milk tank corresponding to the strip scraper rods 4 will be scraped clean, and there may be milk residue attached to the strip scraper rods 4, so the scraper rod cleaning mechanism will clean the strip scraper rods 4 thereafter. The specific cleaning process is as follows: when the rotating table 2 stops rotating, The two groups of telescopic arms 3 are synchronously extended and retracted inward for a certain distance, and the limit pins 10 connected to the telescopic arms 3 will slide in the corresponding strip limit grooves 11. At this time, the retraction stroke of the telescopic arms 3 is controlled to ensure that the limit pins 10 will not conflict with one end of the strip limit grooves 11. Then, during the retraction of the telescopic arms 3, the current strip slide 7 will not retract with the telescopic arms 3. When the telescopic arms 3 stop retracting, the two nozzles 8 provided on one end of the strip slide 7 will be exposed to the outside. Thereafter, the two inclined nozzles 8 are used to spray the two strip scraper rods 4 on the telescopic arms 3. After the strip scraper 4 is rinsed clean, the two sets of telescopic arms 3 will extend outward to their original state again, and then the lifting seat 1 will start the next stage of descent. When the lifting seat 1 stops descending, the scraping and washing assembly will repeat the above-mentioned working process, and before the lifting seat 1 starts the next stage of descent, the scraper cleaning mechanism will clean the strip scraper 4, and finally the entire inner wall of the milk tank will be cleaned by the scraping and washing assembly, and in the process of cleaning the inner wall of the milk tank, the strip scraper 4 will be self-cleaned by the scraper cleaning mechanism, so as to improve the scraping efficiency of the strip scraper 4 itself.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
