[0021] As Figures 1 - 10 shown, a beverage canning device includes a tank body 1. A connecting pipe 101 is fixedly arranged on the top end face of the tank body 1. The top end of the connecting pipe 101 is in a closed state, and the bottom end of the connecting pipe 101 is communicated with the tank body 1. A rotating shaft 7 is rotatably arranged inside the tank body 1 and at the axis position. A stirring rod is fixedly arranged on the outer side of the rotating shaft 7, so as to be able to stir the beverage in the tank body 1, making the pulp in the beverage evenly dispersed in the tank body 1. The bottom end of the rotating shaft 7 is rotationally matched with the top of the tank body 1.

[0022] Referring to Figure 3 shown, a bottom plate 6 is arranged inside the connecting pipe 101 and near the bottom end. A plurality of filter holes are evenly formed in the bottom plate 6. The rotating shaft 7 passes through the bottom plate 6 and is rotationally matched with the bottom plate 6 through a tapered roller bearing. A filtering unit is sleeved outside the bottom plate 6. Through this structure, larger-sized pulp in the beverage can be filtered, thereby improving the taste of the beverage. The filtering unit can move in the vertical direction relative to the connecting pipe 101, and a retaining ring 4 is arranged inside the filtering unit. The retaining ring 4 is fixedly connected with the inner wall of the connecting pipe 101. The filtering unit is clamped with the retaining ring 4; A pressing plate 10 is arranged above the bottom plate 6. A scraper 9 is arranged on the top surface of the pressing plate 10. During actual use, the beverage poured into the tank body 1 can flow out from the filtering unit between the scraper 9 and the retaining ring 4. Combining Figure 3 、 Figure 7 shown, a plurality of through round holes 20 are formed in both the scraper 9 and the pressing plate 10. Vertically, the round holes 20 on the scraper 9 are staggered from the round holes 20 on the pressing plate 10. Through this structure, when the scraper 9 and the pressing plate 10 are in a fitting state, the bottom plate 6 below can be sealed.

[0023] In order to drive the scraper 9 and the pressing plate 10 to move in the vertical direction, an inclined arc-shaped groove 703 is provided on the outer circumferential wall of the rotating shaft 7. A first convex block 901 matching the arc-shaped groove 703 is provided on the scraper 9, and a second convex block 1001 matching the arc-shaped groove 703 is elastically provided on the pressing plate 10. During the rotation of the rotating shaft 7, the cooperation between the arc-shaped groove 703 and the first convex block 901 can drive the scraper 9 to move upward. When the scraper 9 moves upward and leaves the pressing plate 10, the second convex block 1001 on the pressing plate 10 can pop out and cooperate with the arc-shaped groove 703, so that the pressing plate 10 can move upward. As the scraper 9 and the pressing plate 10 are separated, the beverage poured into the tank body 1 can fall above the bottom plate 6 through the round holes 20 on the scraper 9 and the pressing plate 10; The scraper 9 is matched with the filtering unit through a traction assembly. When the scraper 9 moves upward to the bottom of the retaining ring 4, the retaining ring 4 is disconnected from the filtering unit. As the scraper 9 moves downward, the scraper 9 can drive the filtering unit to move downward through the traction assembly, so that the unused part of the filtering unit moves between the retaining ring 4 and the scraper 9.

[0024] The above-mentioned filtering unit includes two arc-shaped filter meshes 19 and a connecting rod 5 fixedly arranged between the two filter meshes 19. Both ends of the connecting rod 5 extend to the outside of the filter mesh 19. Specifically, in combination with Figure 6 As shown, a cylindrical structure can be formed by enclosing between the filter mesh 19 and the connecting rod 5. A first clamping groove 401 is opened on the outer side surface of the retaining ring 4. The first clamping groove 401 is a strip-shaped structure and is arranged along the axial direction of the retaining ring 4. The side of the connecting rod 5 far from the connecting pipe 101 is inserted into the first clamping groove 401. In combination with Figure 3 As shown, a second clamping groove 1011 is opened on the inner wall of the connecting pipe 101, and the side of the connecting rod 5 far from the retaining ring 4 is inserted into the second clamping groove 1011. Through this structure, the connecting rod 5 can only move vertically between the retaining ring 4 and the connecting pipe 101. In combination with Figure 3 、 Figure 7 As shown, positioning grooves 3 are opened on the outer circumferential walls of the scraper 9 and the pressing plate 10, and the side of the connecting rod 5 far from the connecting pipe 101 is inserted into the positioning grooves 3. Through this structure, the scraper 9 and the pressing plate 10 can only move in the vertical direction.

[0025] Circular grooves 702 are opened on the outer circumferential wall of the rotating shaft 7 and at both ends of the arc-shaped groove 703. The two circular grooves 702 are both communicated with the arc-shaped groove 703. Referring to Figures 7 - 9 As shown, guide plates 22 are hinged at both ends of the arc-shaped groove 703. The guide plates 22 are elastically matched with the rotating shaft 7, and the guide plates 22 are located at the junction of the arc-shaped groove 703 and the circular groove 702. In combination with Figure 9As shown, the guide plate 22 can only rotate clockwise relative to the rotating shaft 7. In the initial state, the first bump 901 and the second bump 1001 are both located in the annular groove 702 below the arc groove 703. Combining again with Figure 9 As shown, with the forward rotation of the rotating shaft 7, the first bump 901 and the second bump 1001 will pass through the lower guide plate 22 and drive the guide plate 22 to deflect. With the reverse rotation of the rotating shaft 7, the first bump 901 and the second bump 1001 can both enter the arc groove 703 through the lower guide plate 22; Furthermore, combining Figures 3 - 5 As shown, magnetic blocks 12 are slidably arranged on both the top surface and the bottom surface of the pressing plate 10. A pulling rope 11 is fixedly arranged between the magnetic block 12 and the second bump 1001. The pulling rope 11 passes through the pressing plate 10 and is slidably matched with it. Magnetic plates 13 matched with the magnetic blocks 12 are fixedly embedded on both the top surface of the bottom plate 6 and the bottom surface of the scraping plate 9. And the opposite surfaces of the magnetic block 12 and the magnetic plate 13 have different magnetic poles. With this structure, when the pressing plate 10 is between the scraping plate 9 and the bottom plate 6 and in contact with both of them, the resultant force applied by the two pulling ropes 11 can drive the second bump 1001 to contract into the pressing plate 10.

[0026] Combining Figures 3 - 5 As shown, the traction assembly includes a push block 17 elastically matched with the scraping plate 9. The push block 17 is located at the inner end face of the positioning groove 3 on the scraping plate 9. An inclined guide surface 1701 is arranged at one end of the push block 17 close to the connecting rod 5. A plurality of notches 501 are uniformly formed on one side surface of the connecting rod 5 far from the connecting pipe 101. When the push block 17 is in the ejected state and inserted into the notches 501, the cooperation between the push block 17 and the notches 501 can drive the connecting rod 5 to move downward; In order to realize the locking between the connecting rod 5 and the retaining ring 4, a retaining block 16 is elastically installed on the surface of the first clamping groove 401 opposite to the connecting rod 5. A magnet 14 is slidably arranged at the bottom end face of the retaining ring 4. A traction rope 15 is fixedly arranged between the magnet 14 and the retaining block 16. And the traction rope 15 passes through the retaining ring 4 and is slidably matched with it. In order to release the locking between the connecting rod 5 and the retaining ring 4, a magnetic strip 18 is fixedly embedded on the top surface of the scraping plate 9. The opposite surface of the magnetic strip 18 and the magnet 14 has different magnetic poles. Specifically, when the scraping plate 9 moves upward to the bottom surface of the retaining ring 4, the suction force between the magnetic strip 18 and the magnet 14 can pull the traction rope 15, so that one end of the retaining block 16 moves out of the notch 501.

[0027] In the initial state, the scraping plate 9 is in contact with the pressing plate 10 and is located at the top surface of the bottom plate 6. At this time, the beverage poured into the tank body 1 can only flow through the space between the retaining ring 4 and the scraping plate 9. The filter screen 19 between the retaining ring 4 and the scraping plate 9 can filter large-particle pulp in the beverage. By driving the stirring rod outside it to rotate forward through the rotating shaft 7, the beverage in the tank body 1 can be stirred, so that the pulp is evenly dispersed in the tank body 1. After using for a period of time or when the staff detects that the pulp content in the beverage decreases, the rotating shaft 7 can be driven to rotate in the reverse direction. According to the above description, when the rotating shaft 7 rotates in the reverse direction, the first convex block 901 will slide along the annular groove 702 below the arc-shaped groove 703 and enter the arc-shaped groove 703 upward through the lower guide plate 22, thereby causing the scraping plate 9 to move upward along the rotating shaft 7. Combined with Figures 3 - 4 As shown, when the scraping plate 9 moves upward and separates from the pressing plate 10, the acting force of the single pulling rope 11 is no longer sufficient to pull the second convex block 1001, so that the second convex block 1001 can pop out. When the second convex block 1001 enters the arc-shaped groove 703 along the lower guide plate 22, the pressing plate 10 can also move upward relative to the rotating shaft 7. Therefore, through this structure, the scraping plate 9 and the pressing plate 10 can be successively driven to move upward. Since the scraping plate 9 and the pressing plate 10 are separated from each other, the beverage can fall onto the bottom plate 6 through the round holes 20 on the scraping plate 9 and the pressing plate 10. During this process, the pulp scraped off from the filter screen 19 by the scraping plate 9 will flow onto the bottom plate 6 together with the liquid beverage. The filter holes provided on the bottom plate 6 can prevent large-particle pulp from passing through; When the scraping plate 9 moves upward to a state in contact with the retaining ring 4, the first convex block 901 will enter the annular groove 702 above the arc-shaped groove 703 from the arc-shaped groove 703. Combined with Figure 9 As shown, during the reverse rotation of the rotating shaft 7, the first convex block 901 can drive the upper guide plate 22 to deflect and cross the guide plate 22. Then, the second convex block 1001 on the pressing plate 10 will also enter the annular groove 702 upward through the arc-shaped groove 703. At this point, both the first convex block 901 and the second convex block 1001 are placed in the upper annular groove 702; Combined with Figure 5, when the scraper 9 contacts the bottom surface of the retaining ring 4, the attraction between the magnetic strip 18 and the magnet 14 can pull the traction rope 15, so that one end of the stop block 16 moves out of the slot 501, and because the push block 17 pops out and inserts into the slot 501 on the side of the connecting rod 5 and below the retaining ring 4, the scraper 9 can drive the connecting rod 5 to move downward. As the scraper 9 moves downward, the magnet 14 attracted by the magnetic strip 18 moves downward for a distance and finally disengages from the magnetic strip 18. Specifically, when the rotating shaft 7 rotates forward again, the first protrusion 901 and the second protrusion 1001 will pass through the guide plate 22 and enter the arc groove 703 downward. As the rotating shaft 7 continues to rotate, the arc groove 703 is used to act on the first protrusion 901 and the second protrusion 1001. The force can drive the scraper 9 and the pressure plate 10 to move downward to the bottom plate 6. When the scraper 9 and the pressure plate 10 are located at the bottom plate 6, the first protrusion 901 and the second protrusion 1001 return to the annular groove 702 below the arc groove 703. During this process, the push block 17 can drive the connecting rod 5 and the filter 19 to move downward. When the pressure plate 10 is in contact with the bottom plate 6, the stopper 16 on the retaining ring 4 is aligned with the notch 501 on the connecting rod 5, so that the stopper 16 can pop out and be inserted into the notch 501 to maintain the stability of the connecting rod 5 and the filter 19. At this point, a part of the filter 19 that was originally placed on the outside of the retaining ring 4 and was not used slides down between the retaining ring 4 and the scraper 9, so that the large particles of pulp in the beverage can be filtered again.

[0028] To sum up, this device drives the rotating shaft 7 to rotate, so that the scraper 9 and the pressing plate 10 can move upward successively, which causes the beverage poured into the tank body 1 to flow to the bottom plate 6 through the circular holes 20 on the scraper 9 and the pressing plate 10. During this process, the pulp scraped from the filter 19 by the scraper 9 can be driven to the bottom plate 6. When the scraper 9 and the pressing plate 10 move downward, the push block 17 and the slot 501 can drive the connecting rod 5 and the filter 19 to move downward, so that the large particles of pulp in the beverage can be filtered through the unused filter 19.

[0029] like Figures 3 - 10 As shown, a spiral limiting groove 701 is further provided on the outer peripheral wall of the rotating shaft 7, and the limiting groove 701 is located at a lower position of the bottom plate 6, and a blocking rod 8 is installed on the rotating shaft 7 at the limiting groove 701. Specifically, a collar 24 is sleeved on the rotating shaft 7, and the blocking rod 8 is fixedly arranged on the outer peripheral wall of the collar 24, and a limiting block 23 that slides with the limiting groove 701 is elastically installed on the inner wall of the collar 24. A support ring 25 is provided below the collar 24, and the support ring 25 is fixedly sleeved on the outer side of the rotating shaft 7. Figure 11As shown, the end of the limit block 23 away from the shift lever 8 is a spherical structure. By setting the spherical structure, when the force between the end of the limit block 23 and the limit groove 701 is relatively large, one end of the limit block 23 can move out of the limit groove 701. Specifically, when the shift lever 8 drives the connecting rod 5 and the filter screen 19 to move upward to the extreme position, the limit block 23 can move out of the limit groove 701. Further, referring to Figure 5 As shown, the inner bottom surface of the notch 501 is set as the second inclined surface 5011, and one side of the stop block 16 close to the connecting rod 5 is set as the first inclined surface 1601. During actual use, when the connecting rod 5 and the filter screen 19 move downward to the extreme position and fall above the shift lever 8, the shift lever 8 can be limited by the connecting rod 5, thereby preventing the shift lever 8 from continuing to rotate along with the rotating shaft 7. At this time, during the rotation of the rotating shaft 7, the shift lever 8 can be driven to move upward through the cooperation of the limit groove 701 and the limit block 23, thereby driving the connecting rod 5 and the filter screen 19 to move upward. During this process, the push block 17 can be compressed into the scraper 9 through the second inclined surface 5011 on the notch 501. At the same time, the stop block 16 can be compressed into the retaining ring 4 through the second inclined surface 5011, so as to prevent interference between the connecting rod 5 and the push block 17 and the stop block 16 during the process of the shift lever 8 driving the connecting rod 5 to move upward.

[0030] In summary, through the cooperation of the shift lever 8 and the connecting rod 5 provided in this device, the connecting rod 5 and the filter screen 19 can be driven to move upward and reset during the rotation of the rotating shaft 7, which is beneficial to the repeated use of the filter screen 19. Of course, before the filter screen 19 is reset, the filter screen 19 can be rinsed with clean water.

[0031] A diversion pipe 2 is connected and communicated at the top end of the connecting pipe 101. The diversion pipe 2 is connected and communicated with a storage tank for storing beverage raw materials outside, which is beneficial to introducing the raw materials into the tank body 1. And a drain pipe is connected and communicated at a position close to the lower part on the outer side of the tank body 1, which is beneficial to filling the beverage in the tank body 1 into the bottle body. Of course, the pipeline connection and valve control and other structures for beverage filling are all mature technical means and will not be elaborated here.

[0032] The top end of the rotating shaft 7 passes through the connecting pipe 101 and is rotationally matched with it. A motor is installed on the connecting pipe 101, and the output shaft of the motor is in transmission cooperation with the rotating shaft 7 to drive the rotating shaft 7 to rotate.

[0033] Referring to Figure 3 As shown, the top end of the retaining ring 4 extends outward, which is beneficial to the fixed connection with the connecting pipe 101.

[0034] Referring to Figure 4As shown, a first groove for slidingly mating with the magnetic block 12 is formed on the pressing plate 10. Both the pressing plate 10 and the scraping plate 9 are arranged in a circular ring shape. The above-mentioned first convex block 901 is fixedly arranged at the inner wall of the scraping plate 9. A second groove for slidingly mating with the second convex block 1001 is formed at the inner wall of the pressing plate 10. A spring is fixedly arranged between the inner end face of the second groove and the second convex block 1001.

[0035] An installation groove for slidingly mating with the push block 17 is formed at the inner end face of the positioning groove 3 on the scraping plate 9. A first spring is fixedly arranged between the inner end face of the installation groove and the push block 17. A first sliding groove for slidingly mating with the blocking block 16 is formed on the inner wall of the first clamping groove 401. A second spring is fixedly arranged between the inner end face of the first sliding groove and the blocking block 16, and the spring constant of the second spring is greater than that of the first spring. With this structure, when the scraping plate 9 moves upward, the cooperation between the blocking block 16 and the notch 501 can keep the connecting rod 5 stable, which is beneficial for the push block 17 to move upward relative to the connecting rod 5. A second sliding groove for slidingly mating with the magnet 14 is formed at the bottom surface of the retaining ring 4.

[0036] Combined Figures 3 - 4 、 Figure 7 As shown, raised portions 21 are fixedly arranged on the surfaces of the pressing plate 10 and the scraping plate 9 facing each other. The raised portion 21 on the scraping plate 9 is vertically aligned with the circular hole 20 on the pressing plate 10, and the raised portion 21 on the pressing plate 10 is vertically aligned with the circular hole 20 on the scraping plate 9. With this structure, when the scraping plate 9 and the pressing plate 10 move downward, the raised portion 21 on the scraping plate 9 will be inserted into the circular hole 20 on the pressing plate 10, so that the bottom surface of the pressing plate 10 is a complete planar structure, which can squeeze the large-particle pulp on the bottom plate 6 to break it into small-particle pulp and make it possible to pass through the bottom plate 6.

[0037] Referring to Figures 9 - 10 As shown, a notch for cooperating with the guide plate 22 is formed at the inner wall of the arc-shaped groove 703. One end of the guide plate 22 away from the annular groove 702 is located at the notch and is hinged to the rotating shaft 7. In actual use, it can be connected by a hinge or a hinge. An arc-shaped spring is fixedly arranged between the end face of the guide plate 22 near the notch and the side wall of the notch.

[0038] A circular hole for slidingly mating with the limiting block 23 is formed at the inner wall of the collar 24. A limiting spring is fixedly arranged between the inner end face of the circular hole and the limiting block 23.
