Description

Technical Field

[0001] This invention relates to the field of yogurt filling production equipment technology, specifically a jam adding device for a bowl-type yogurt filling machine. Background Technology

[0002] Double-layer yogurt is a popular product in the yogurt market because it has the texture of both jam and yogurt. The production of double-layer yogurt requires filling the bottom of the cup with jam first, and then filling it with milk liquid, which is fermented to form a stable layered structure.

[0003] Existing bowl-type yogurt filling machines are only designed for milk filling and lack compatible jam-adding devices. Furthermore, commercially available jam-adding devices suffer from issues such as mismatched structural dimensions and poor interoperability with filling machines. As a result, they cannot be directly applied to existing bowl-type yogurt production lines in the production workshop. It is necessary to purchase new filling machines with jam-adding capabilities and re-lay out the production line before they can be used for the production of yogurt products such as double-layer yogurt that require jam. This process is difficult, time-consuming, and costly. Summary of the Invention

The through holes I301 and the threaded holes I501 are fixedly connected by bolts. The top plate has two through holes II401, which are coaxial with the threaded holes I501 on the top surfaces of the two support columns I5. The through holes II401 and the threaded holes I501 are fixedly connected by bolts.

[0022] This invention uses a servo motor 2 to drive the ceramic valve core 9 to rotate to different positions within the valve body 1 to establish a jam intake channel and a jam discharge channel. When the suction piston 14 slides up and down within the piston tube 13, the seal formed by the sealing ring I 16 is not broken. Therefore, the upward sliding of the piston plate 1401 creates jam intake, and the downward sliding of the piston plate 1401 creates jam discharge. Figure 3 As shown, at this time, feed hole I 904, feed hole II 1002, inlet hole 104 and feed pipe 11 are coaxial and connected; suction hole I 906, suction hole II 1004, suction hole 106 and piston pipe 13 are coaxial and connected; discharge hole I 905 is abutted against the inner wall of valve core hole 1001, and discharge hole I 905 is blocked by the inner wall of valve core hole 1001; discharge hole II 1003 is blocked by the outer wall of valve core column 901. At this time, the piston rod of cylinder 6 retracts, causing suction piston 14 to slide upward inside piston pipe 13. During the upward sliding of suction piston 14 inside piston pipe 13, the jam contained in storage tank 8 enters feed hole I 904, suction hole I 906, suction hole II 1004, suction hole 106 and piston pipe 13 below piston plate 1401 through bent pipe 7 and feed pipe 11. It is necessary to add to the yogurt bowl. When adding jam, align the filling tube 12 with the yogurt bowl and start the servo motor 2. The servo motor 2 drives the ceramic valve core 9 to rotate, so that the feed hole II 1002 is blocked by the outer wall of the valve core column 901. The feed hole I 904, the suction hole II 1004, the suction hole 106 and the piston tube 13 are coaxial and connected. The suction hole I 906 is pressed against the inner wall of the valve core hole 1001 and is blocked by the inner wall of the valve core hole 1001. The discharge hole I 905, the discharge hole II 1003, the discharge hole 105 and the filling tube 12 are coaxial and connected. At this time, the piston rod of the control cylinder 6 extends and drives the suction piston 14 to slide downward inside the piston tube 13. During the downward sliding of the suction piston 14 inside the piston tube 13, the jam is added to the yogurt bowl through the discharge hole I 905, the discharge hole II 1003, the discharge hole 105 and the filling tube 12.

[0023] The dynamic sealing assembly 15 is common knowledge in this field and generally comes in the form of single / double end mechanical seals, skeleton oil seals, PTFE lip seals, labyrinth seals, or O-rings and grooved rotary seals. In actual use, it can be flexibly selected as long as it can meet the stable rotation and sealing of the ceramic valve core 9 and the hygiene requirements of food production. It will not be described or introduced in detail here.

[0024] To ensure the stable rotation of the front shaft 902 and the rear shaft 903 within the shaft hole 107, bearings can be installed between the front shaft 902 and the shaft hole 107 and between the rear shaft 903 and the shaft hole 107. The use of bearings and related accessories is common knowledge in this field and will not be described or introduced in detail here.

[0025] In this invention, such as Figure 6 As shown, the inlet hole 104, suction hole 106, and discharge hole 105 form a "┤" shape and will not change. Since the sealing sleeve 10 is rectangular with the same internal dimensions as the rectangular valve cavity 103, the sealing sleeve 10 will not rotate within the valve body 1. The feed hole II 1002, discharge hole II 1003, and suction hole II 1004 are always formed as shown. Figure 10 The “┤” shape shown is due to the ceramic valve core 9 needing to rotate to different positions during use. Therefore, the “┴” shape formed by the feed hole I904, discharge hole I905, and suction hole I906 will change due to rotation.

[0026] The seal formed by the sealing sleeve 10 and the valve core column 901 prevents the jam in the feed hole I 904, discharge hole I 905 and suction hole I 906 from leaking into the valve core hole 1001 or the rectangular valve cavity 103.

[0027] The inner guide radius 1201 serves to guide the jam discharged from the filling tube 12, thus preventing the jam from splashing or dripping at the port of the filling tube 12.

[0028] The storage tank 8 is used to hold jam. Depending on the actual production requirements, the bend 7 can be made of either a rigid pipe or a flexible pipe. The filter assembly 803 filters out large particles in the jam, such as large pieces of fruit pulp, preventing them from clogging the valve body 1. The cover 805 seals the storage tank 8, ensuring the hygiene of the jam inside. The vent valve 25 ensures both hygiene and ventilation inside the storage tank 8, preventing a vacuum from forming inside and preventing the jam from being sucked out. The filling hole 806 allows jam to be added without removing the cover 805. The blind flange 807 seals the filling hole 806. The handle 26 facilitates operation of the cover 805 by staff.

[0029] The inner diameter of the feed pipe 11 is equal to the inner diameter of the inlet hole 104, which is greater than the inner diameter of the feed hole II 1002, which is greater than the inner diameter of the feed hole I 904. The inner diameter of the filling pipe 12 is equal to the inner diameter of the discharge hole 105, which is greater than the inner diameter of the discharge hole II 1003, which is greater than the inner diameter of the discharge hole I 905. The inner diameter of the piston pipe 13 is equal to the inner diameter of the suction hole 106, which is greater than the inner diameter of the suction hole II 1004, which is greater than the inner diameter of the suction hole I 906. The inner diameter of the feed hole I 904 is equal to the inner diameter of the discharge hole I 905, which is equal to the inner diameter of the suction hole I 906. The inner diameter of the inlet hole 104 is equal to the inner diameter of the discharge hole 105, which is less than the inner diameter of the suction hole 106. The inner diameter of the feed hole II 1002 is equal to the inner diameter of the discharge hole II 1003, which is less than the inner diameter of the suction hole II 1004. The effect of the above hole diameter settings is that in each passage, from the outside of the valve body 1 to the inside of the valve body 1, the diameter of the holes connected on the same axis decreases sequentially, which facilitates the achievement of a stable seal.

[0030] The present invention divides the valve body 1 into a valve seat 101 and a valve cover 102, mainly to facilitate the installation and removal of various internal components of the valve body 1.

[0031] The base plate 3, top plate 4 and support column I5 are provided with a connection basis for the present invention. The base plate 3 and top plate 4 can be connected to the motion execution parts of the existing filling machine in the production workshop. The motion execution parts drive the present invention to add jam to different yogurt bowls in sequence. After the milk is added by the existing filling machine, the assembly line filling of yogurt products such as double-layer yogurt that require jam can be completed.

[0032] The main difference between Embodiment 2 and Embodiment 1 of the jam-adding device for a bowl-type yogurt filling machine of the present invention is that Embodiment 2 uses three valve bodies 1 together to add jam to three bowl-type yogurts at one time.

[0033] like Figures 15-20 As shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the valve body 1 includes three valves. A connecting pipe 17 is fixedly connected to the outer wall of the valve cover 102 of each valve body 1. The connecting pipe 17 is coaxial with and communicates with the shaft hole 107 of the valve cover 102. The three valve bodies 1 are linearly and evenly distributed. The rear end shaft 903 of the ceramic valve core 9 in the front valve body 1 and the front end shaft 902 of the ceramic valve core 9 in the rear valve body 1 are fixedly connected to each other inside the connecting pipe 17. The front end shaft 902 of the ceramic valve core 9 inside the valve body 1 closest to the servo motor 2 in body 1 is connected to the output shaft of the servo motor 2 via a coupling; the bottom wall of the storage tank 8 is provided with three discharge holes 801, and three discharge pipes 804 are fixedly connected to the bottom surface of the storage tank 8. The three discharge pipes 804 are coaxial with and connected to the three discharge holes 801 respectively. There are three bends 7, and the three bends 7 are respectively connected between the three discharge pipes 804 and the three feed pipes 1111 on the valve body 1.

[0034] The upper part of the piston rod 1402 of the suction piston 14 on the three valve bodies 1 is provided with external threads 1404. Each piston rod includes a cylinder connecting plate 18, a support rod II 19, and a piston connecting plate 20. The piston connecting plate 20 is located above the piston tube 13 and has three through holes VII 2001. The external threads 1404 of the three piston rods 1402 pass through the three through holes VII 2001 respectively. A nut is connected to each external thread 1404. There are two sets of nuts, which abut against the top and bottom surfaces of the piston connecting plate 20, respectively. Each set of nuts consists of two nuts, which abut against each other. The cylinder connecting plate 18 has a through hole V1801 at its center, and the piston rod end face of the cylinder 6 has a threaded hole II601. The piston rod end face of the cylinder 6 is connected to the top surface of the cylinder connecting plate 18. The threaded hole II601 and the through hole V1801 are connected by bolts. The bolts pass through the through hole V1801 and then connect to the threaded hole II601. Inside, support column II19 connects cylinder connecting plate 18 and piston connecting plate 20. There are two support columns II19, each with a threaded hole III1901 at its center. The threaded hole III1901 is positioned along the height of the support column II19 and penetrates through it. The cylinder connecting plate 18 has two through holes VI1802, which are coaxial with the threaded holes III1901 of the two support columns II19. 1802 is fixedly connected to the two threaded holes Ⅲ1901 by bolts. After the bolts pass through the through hole Ⅵ1802, they are threaded into the threaded hole Ⅲ1901. The piston connecting plate 20 is provided with two through holes Ⅸ2003. The two through holes Ⅸ2003 are coaxial with the threaded holes Ⅲ1901 of the two support columns Ⅱ19 respectively. The two through holes Ⅸ2003 are fixedly connected to the two threaded holes Ⅲ1901 by bolts. After the bolts pass through the through holes Ⅸ2003, they are connected into the threaded hole Ⅲ1901.

[0035] The piston connecting plate 20 has two through holes VIII 2002. Two guide posts 21 are fixedly connected to the top surface of the piston connecting plate 20. Each guide post 21 has a threaded hole IV 2101 on its bottom surface. The two through holes VIII 2002 are coaxial with the threaded holes IV 2101 of the two guide posts 21. The two through holes VIII 2002 and the two threaded holes IV 2101 are fixedly connected by bolts. The bolts pass through the through holes VIII 2002 and are connected to the threaded holes IV 2101. The top plate 4 has two through holes IV 403. Guide sleeves 22 are connected to each hole IV403. The top surface of the guide sleeve 22 is provided with a flange. The outer diameter of the flange of the guide sleeve 22 is greater than the inner diameter of the through hole IV403 and the outer diameter of the guide sleeve 22. The flange of the guide sleeve 22 is supported on the top surface of the top plate 4. The flange of the guide sleeve 22 is connected to the top plate 4 by bolts. The flange of the guide sleeve 22 is provided with a hole for the bolt to pass through. The top plate 4 is provided with a bolt hole for bolt connection. The two guide pillars 21 are coaxial with the two guide sleeves 22. The two guide pillars 21 are slidably connected in the two guide sleeves 22 respectively.

[0036] In Embodiment 2, three valve bodies 1 are provided. If each valve body 1 is equipped with a separate cylinder 6, on the one hand, the three cylinders 6 need to be controlled separately and synchronized, and on the other hand, installation space for the three cylinders 6 needs to be reserved. In order to solve the above problems, this embodiment uses the same cylinder 6 for the three valve bodies 1. In this embodiment, the piston rod of the cylinder 6 moves to drive the cylinder connecting plate 18 to rise and fall. The rising and falling of the cylinder connecting plate 18 drives the piston connecting plate 20 to rise and fall through the two support columns II. The rising and falling of the piston connecting plate 20 drives the rising and falling of the three suction pistons 14, thereby realizing the movement of the three suction pistons 14 by one cylinder 6.

[0037] The guide post 21 and guide sleeve 22 guide the lifting and lowering of the cylinder connecting plate 18 and piston connecting plate 20, thus improving the stability of use.

[0038] In this embodiment, the height of the suction piston 14 is adjustable by setting the through hole VII2001, the external thread 1404 and the nut connected to the external thread 1404, which facilitates the installation and debugging of the suction piston 14.

[0039] Example 2 provides a technical solution with three valve bodies 1. In actual use, multiple Examples 2 can be set up in parallel to form multiple more valve bodies 1 technical solutions.

[0040] In this invention, the connection between the discharge pipe 804 and the bend 7, and the connection between the bend 7 and the feed pipe 11, are both made of KF flange. The use of KF flange also requires the installation of sealing rings, sealing ring supports and clamps. In addition to KF flange, other connection methods such as flat flanges or threaded connections can also be used, as long as they can meet the requirements for jam conveying.

[0041] In this invention, the valve body 1, bend 7, storage tank 8, feed pipe 11, filling pipe 12, piston pipe 13, and suction piston 14, which come into contact with the jam, are all made of 304 stainless steel that meets food production requirements; the ceramic valve core 9 is made of ceramic that meets food production requirements; the sealing sleeve is made of polytetrafluoroethylene that meets food production requirements; and the sealing rings I 16, II 23, and III 24 are made of silicone, fluororubber, Teflon, or polyurethane that meet food production requirements.

[0042] In this invention, the ceramic valve core 9 in Embodiment 1 and Embodiment 2 has the same function, such as... Figure 23 and Figure 24 As shown, the ceramic valve core 9 has two working positions, which correspond to the feeding condition and the discharging condition, respectively. like Figure 23As shown, the position of the ceramic valve core 9 during the feeding condition is as follows: feed hole I 904, feed hole II 1002, inlet hole 104 and feed pipe 11 are coaxial and connected; suction hole I 906, suction hole II 1004, suction hole 106 and piston pipe 13 are coaxial and connected; discharge hole I 905 is abutted against the inner wall of valve core hole 1001; discharge hole I 905 is blocked by the inner wall of valve core hole 1001; discharge hole II 1003 is blocked by the outer wall of valve core column 901. like Figure 24 As shown, the position of the ceramic valve core 9 during the discharge condition is as follows: the feed hole II 1002 is blocked by the outer wall of the valve core column 901; the feed hole I 904, the suction hole II 1004, the suction hole 106 and the piston tube 13 are coaxial and connected; the suction hole I 906 is abutted against the inner wall of the valve core hole 1001; the suction hole I 906 is blocked by the inner wall of the valve core hole 1001; the discharge hole I 905, the discharge hole II 1003, the discharge hole 105 and the filling tube 12 are coaxial and connected.

[0043] The switching procedure between feeding and discharging modes is as follows: During the feeding operation, the piston rod of cylinder 6 extends, causing the suction piston 14 to extend into the lower part of piston tube 13. At this time, the suction piston 14 is in a low position, that is, as shown in the figure. Figure 23 The location of the middle suction piston 14; During the feeding process, the piston rod of the control cylinder 6 retracts, causing the suction piston 14 to slide upward inside the piston tube 13. As the suction piston 14 slides upward inside the piston tube 13, the jam contained in the storage tank 8 enters the feed hole I 904, suction hole I 906, suction hole II 1004, suction hole 106, and the piston tube 13 below the piston plate 1401 through the bend 7 and feed pipe 11. When the piston rod of the cylinder 6 retracts and causes the suction piston 14 to change from a low position to a high position, the jam feeding is completed. It is important to note that the high position of the suction piston 14 should not cause the piston plate 1401 to disengage from the piston tube 13 and a certain amount of clearance should be maintained to avoid damaging the sealing environment below the piston plate 1401 formed by the sealing ring I 16. Figure 24 The position of the suction piston 14 shown in the figure; After the jam is fed, align the filling tube 12 with the yogurt bowl and start the servo motor 2. The servo motor 2 drives the ceramic valve core 9 to change from the feeding position to the discharging position, that is, the ceramic valve core 9 moves from the feeding position to the discharging position. Figure 23 The position shown changes when rotated 90° clockwise as follows: Figure 24As shown, when the servo motor 2 drives the ceramic valve core 9 to rotate, the piston rod of the cylinder 6 does not move, that is, the suction piston 14 will not slide, and the jam will not leak. When the ceramic valve core 9 is accurately positioned in the discharge condition, the piston rod of the control cylinder 6 extends and drives the suction piston 14 to slide downward inside the piston tube 13. During the downward sliding of the suction piston 14 inside the piston tube 13, the jam is added to the yogurt bowl through the discharge hole I 905, discharge hole II 1003, discharge hole 105 and filling tube 12. When the piston rod of the cylinder 6 reaches the low position, the addition of jam to the yogurt bowl is completed. After adding the jam, start the servo motor 2 to drive the ceramic valve core 9 from the discharge position to the feed position, that is, the ceramic valve core 9 moves from the discharge position to the feed position. Figure 24 The position shown is rotated 90° counterclockwise to the position shown in Figure 23. When the servo motor 2 drives the ceramic valve core 9 to rotate, the piston rod of the cylinder 6 does not move. Then, the above actions of the cylinder 6, the ceramic valve core 9, and the switching between the feeding and discharging modes are repeated to achieve repeated actions.

[0044] It is important to note that before adding jam once and before adding jam again, you should use the milk filling setting to fill the milk in the yogurt bowl.

[0045] Before formal production, this invention can achieve quantitative addition of jam by determining the amount of jam discharged from the filling pipe 12 to a set value. The amount of jam added is mainly controlled by adjusting the low and high positions of the cylinder 6.

[0046] In addition, during the feeding process, jam may also remain in the discharge port I905; during the discharge process, jam may also remain in the suction port I906; and jam may also remain at the fastener connection. These remaining jams will not affect the intake and discharge of jam, nor will they affect the quantitative addition of jam.

[0047] Before adding jam for the first time, the curved pipe 7 and the feed pipe 11 should be filled with jam. At this time, the action of cylinder 6, the action of ceramic valve core 9 and the switching between feeding and discharging conditions can be repeated. Under the discharge condition, the jam can be stably discharged from the filling pipe 12. Ensure that the jam discharged from the filling pipe 12 does not contain air and reaches the set addition amount before normal production.

[0048] Considering that the invention needs to be cleaned during equipment maintenance or when changing jam types, disassembly followed by cleaning would greatly increase cleaning efficiency but also increase labor intensity. Therefore, Figure 25 and Figure 26 As shown, the ceramic valve core 9 of the present invention also has two cleaning positions, which correspond to cleaning condition I and cleaning condition II respectively. During cleaning condition I, the position of the ceramic valve core 9 is as follows: the discharge hole I 905, the feed hole II 1002, the inlet hole 104 and the feed pipe 11 are coaxial and connected; the suction hole II 1004 is blocked by the inner wall of the valve core hole 1001; the feed hole I 904 is abutted against the inner wall of the valve core hole 1001; the feed hole I 904 is blocked by the inner wall of the valve core hole 1001; the suction hole I 906, the discharge hole II 1003, the discharge hole 105 and the filling pipe 12 are coaxial and connected. During cleaning condition II, the positions of the ceramic valve core 9 are as follows: suction hole I 906, feed hole II 1002, inlet hole 104 and feed pipe 11 are coaxial and connected; discharge hole I 905, suction hole II 1004, suction hole 16 and piston pipe 13 are coaxial and connected; feed hole I 904, discharge hole II 1003, discharge hole 105 and filling pipe 12 are coaxial and connected.

[0049] When cleaning in cleaning condition I, disconnect the bend 7 from the feed pipe 11, remove the suction piston 14 from the piston pipe 13, and then connect the water inlet pipe through the feed pipe 11 and the filling pipe 12 to introduce cleaning water to clean the inside of the valve body 1. During the cleaning process, the ceramic valve core can be rotated to achieve all-round cleaning of the inside of the valve body 1.

[0050] When using cleaning mode II, the jam in storage tank 8 can be removed, cleaning water can be added to storage tank 8, and the suction piston 14 can be continuously moved up and down by cylinder 6 to clean storage tank 8, bend pipe 7 and valve body 1. During the cleaning process, the ceramic valve core can be rotated to achieve all-round cleaning of the inside of valve body 1.

[0051] This invention can be installed on existing bowl-type yogurt filling machines and production lines to add jam without affecting the normal use and production of the existing machines and lines. It eliminates the need for large-scale modifications to existing machines and lines, avoids the need to purchase new machines or re-lay out production lines, is easy to implement, and reduces economic costs. Furthermore, this invention allows for repeated jam addition, is easy to control, simple to operate, and readily supports automated control, making it suitable for assembly line production with high efficiency.
