Description
Technical Field
[0001] This utility model relates to the field of dairy product production technology, and in particular to a connecting pipe joint and an automatic connecting device for milk collection pipes. Background Technology
[0002] In modern dairy production, milk truck unloading is a crucial step in ensuring the freshness and quality of dairy products. Currently, traditional unloading processes are typically conducted outdoors, relying on manual connection of pipes. This not only poses significant safety risks and high labor intensity but also results in long waiting times, low unloading efficiency, and wear and tear on the collection pipes caused by repeated dragging on the ground. Existing piping systems mostly use flanged or clamp-type rigid connections to connect multiple pipe sections. In actual unloading, this relies on manual connection of the unloading pipes to the milk truck pipes, which is time-consuming and labor-intensive. Furthermore, due to the inherent errors in manual operation, torque cannot be controlled during connection, and leaks or excessive torque leading to pipe deformation are common problems. Therefore, how to avoid manual labor, ensure quick and accurate pipe connections with good sealing, and achieve automated unloading to improve efficiency and reduce labor costs is a problem that researchers in this field need to solve. Utility Model Content

The connector body is provided with a number of ball rings, and the number of ball rings are sleeved on the outside of the milk collection tube.
[0007] The other end of the connector body away from the milk collection tube is screwed to the milk cart connector.

Among the X-axis, Y-axis, and Z-axis, each pair is perpendicular to the other.
[0016] Optionally, the three-axis displacement adjustment assembly includes a Z-axis guide rail, an X-axis crossbeam, a vertical beam, and a Y-axis track.

[0042] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.
[0043] like Figures 1-11 As shown, this embodiment provides a connecting pipe connector, including a connector body 10, a drive assembly 20, and a milk collection tube 30. One end of the milk collection tube 30 is screwed to the connector body 10, and the other end is connected to the milk tank. The drive assembly 20 is fixed to the milk collection tube 30 and movably connected to the connector body 10. A plurality of ball bearing rings 14 are provided inside the connector body 10, and the plurality of ball bearing rings 14 are sleeved on the outside of the milk collection tube 30. The other end of the connector body 10 away from the milk collection tube 30 is screwed to the milk cart connector 400. The drive assembly 20 can drive the connector body 10 to rotate relative to the milk collection tube 30 and the milk cart connector 400, and cause the connector body 10 to move along the direction from the milk collection tube 30 to the milk cart connector 400 until the milk collection tube 30 and the milk cart connector 400 are connected.
[0044] On the other hand, the automatic connection device for the milk collection tube includes a connecting tube connector, a clamp 210, a three-axis displacement adjustment assembly, and a telescopic rod 300. The connecting tube connector is fixed in the clamp 210, the clamp 210 is set on the three-axis displacement adjustment assembly, and the telescopic rod 300 is telescopically connected to the three-axis displacement adjustment assembly. The milk collection tube 30 in the connecting tube connector is wound around the telescopic rod 300. The connecting tube connector can be driven to move in the X-axis, Y-axis, and Z-axis directions through the three-axis displacement adjustment assembly and the telescopic rod 300. Each of the three axes is perpendicular to the other.
[0045] Specifically, in this embodiment, the connector body 10 and drive assembly 20 in the connecting pipe joint enable automated docking between the milk collection pipe 30 and the milk cart connector 400, effectively avoiding manual operation. Specifically, the connector body 10 is screwed onto the milk collection pipe 30 and the milk cart connector 400. The drive assembly 20 is mounted on the milk collection pipe 30 and movably connected to the connector body 10, thereby driving the connector body 10 to rotate relative to the milk collection pipe 30 and the milk cart connector 400, and enabling it to move along the direction from the milk collection pipe 30 to the milk cart connector 400 until docking is completed. This ensures effective sealing at the pipe connection and avoids errors caused by manual operation, making the pipe connection fast and accurate. Furthermore, a ball ring 14 is provided between the connector body 10 and the milk collection pipe 30 to reduce friction between the milk collection pipe 30 and the connector body 10, ensuring smooth movement of the connector body 10. In this embodiment, the triaxial displacement adjustment component and telescopic rod 300 in the automatic milk collection tube connection device enable automated and intelligent docking of the connecting tube connector and the milk cart connector 400, further improving milk unloading efficiency and reducing labor costs.
[0046] The specific structure of the connecting pipe joint in this embodiment will be described below.
[0047] like Figures 3-11 As shown, in this embodiment, the connecting pipe joint includes a joint body 10, a drive assembly 20, and a milk collection pipe 30. One end of the milk collection pipe 30 is screwed to the joint body 10, and the other end is connected to the milk hopper. The other end of the joint body 10, away from the milk collection pipe 30, can be screwed to the milk cart connector 400, thereby ensuring a stable connection between the milk collection pipe 30 and the milk cart connector 400, allowing milk in the milk hopper to be transported to the milk cart via the milk collection pipe 30 and the milk cart connector 400. Specifically, the drive assembly 20 is fixed to the milk collection pipe 30 and movably connected to the joint body 10. The drive assembly 20 can drive the joint body 10 to rotate relative to the milk collection pipe 30 and the milk cart connector 400, and cause the joint body 10 to move along the direction from the milk collection pipe 30 to the milk cart connector 400 until the milk collection pipe 30 and the milk cart connector 400 are connected. This avoids manual operation, realizes automatic connection between the milk collection pipe 30 and the milk cart connector 400, improves conveying efficiency, and achieves the purpose of automated milk collection operation.
[0048] like Figures 3-7As shown, in this embodiment, the connector body 10 is provided with a milk inlet 101, a connecting cavity 102, a milk outlet 103, a receiving channel 104, and a receiving groove 105, and is provided with an inner gear tooth 11, a threaded portion 12, a telescopic component 13, and a ball ring 14. Optionally, the milk inlet 101, the connecting cavity 102, and the milk outlet 103 are sequentially arranged along the axial direction of the connector body 10. The milk inlet 101 is used to connect to the milk collection tube 30, and the two ends of the connecting cavity 102 are respectively connected to the milk inlet 101 and the milk outlet 103. The milk outlet 103 is used to connect to the milk cart connector 400. Specifically, the milk outlet 103 is set as a tapered opening, and the inner diameter of the milk outlet 103 gradually increases from the side near the connecting cavity 102 to the outer side to guide the milk cart connector 400 and ensure accurate docking. Exemplarily, the inner wall of the milk outlet 103 is smoothly treated to ensure quick docking while avoiding damage during repeated docking. Optionally, the inner diameter of the milk inlet 101 is larger than the inner diameter of the communicating cavity 102 so that the drive assembly 20 can be placed.
[0049] like Figure 7 As shown, further, a plurality of receiving channels 104 are arranged circumferentially within the connector body 10, and the receiving channels 104 extend axially along the connector body 10, with one end connected to the milk inlet 101 and the other end connected to the receiving groove 105, for placing the drive assembly 20 and avoiding its movement. Exemplarily, in this embodiment, three receiving channels 104 are provided, evenly distributed within the connector body 10. Optionally, three receiving grooves 105 are also provided, corresponding one-to-one with the receiving channels 104, and evenly distributed within the connector body 10. Specifically, the receiving grooves 105 extend radially along the connector body 10 and connect to the receiving channels 104, and the receiving grooves 105 and the receiving channels 104 form an L-shaped cavity. Specifically, the telescopic assembly 13 is movably disposed within the receiving groove 105.
[0050] Specifically, an inner gear 11 is provided in the milk inlet 101, and the inner gear 11 meshes with the drive assembly 20, thereby realizing the rotation of the connector body 10 through gear meshing. Optionally, a threaded portion 12 is provided at the end of the connecting cavity 102 facing the milk outlet 103. Specifically, a first threaded end 311 is provided on the milk collection tube 30, and a second threaded end 410 is provided on the milk cart connector 400. Both the first threaded end 311 and the second threaded end 410 are screwed to the threaded portion 12, thereby ensuring that the milk collection tube 30 and the milk cart connector 400 are stably connected through the connector body 10. Exemplarily, the inner diameter of the threaded portion 12 is larger than the inner diameter of the connecting cavity 102, thereby forming a stepped surface to limit the milk collection tube 30, and the inner diameter of the threaded portion 12 is the same as the inner diameter of the milk outlet 103 facing the connecting cavity 102, so as to ensure smooth installation of the milk cart connector 400.
[0051] Furthermore, the receiving groove 105 is located on the side of the threaded portion 12 facing the milk cart connector 400, between the milk outlet 103 and the threaded portion 12. This allows the second threaded end 410 to press against and compress the telescopic component 13 when it is screwed into the threaded portion 12. After the milk collection tube 30 is connected to the milk cart connector 400, the telescopic component 13 loses the pressure from the second threaded end 410 and extends. This allows the opening, closing, forward and reverse rotation of the drive component 20 to be controlled, achieving automated operation and avoiding manual operation.
[0052] like Figure 8 As shown, in this embodiment, the telescopic component 13 is provided with a first spherical surface 131, a connecting post 132, a second spherical surface 133, a fixing rod 134, and an elastic element 135. Specifically, one end of the fixing rod 134 is fixed to the bottom of the receiving groove 105, and the other end passes through the second spherical surface 133. The first spherical surface 131 is connected to the second spherical surface 133 through the connecting post 132. The elastic element 135 is sleeved on the outside of the fixing rod 134 and abuts against the second spherical surface 133. Further, the connecting post 132 is telescopically connected to the fixing rod 134, and the first spherical surface 131 can abut against the second threaded end 410. Under the pressure of the second threaded end 410, the second spherical surface 133 compresses the elastic element 135, and the connecting post 132 contracts under the fixing rod 134, causing the telescopic component 13 to retract into the receiving groove 105, and then extend out of the receiving groove 105 again under the pressure of the second threaded end 410. For example, in other embodiments, the fixing rod 134 can also be configured as a telescopic structure to ensure its compression effect. The specific method can be set as needed, and will not be described in detail here. For example, in this embodiment, the elastic element 135 is configured as a spring, so that after the compressive force is lost, the telescopic component 13 can be restored to its original position under the action of the spring.
[0053] like Figure 4 As shown, in this embodiment, the connector body 10 is provided with a plurality of ball rings 14, and the plurality of ball rings 14 are all disposed in the communicating cavity 102 and sleeved on the outside of the milk collection tube 30, thereby realizing a rolling connection between the milk collection tube 30 and the inner wall of the connector body 10. This ensures that when the connector body 10 rotates relative to the milk collection tube 30, there is no motion interference between the two, guaranteeing a smooth connection of the connector body 10 and avoiding friction between the milk collection tube 30 and the connector body 10. For example, two ball rings 14 are provided, located at one end of the communicating cavity 102 near the threaded portion 12 and the other end near the milk inlet 101, respectively, spaced apart to form multi-point support.
[0054] like Figure 9 and Figure 10As shown, in this embodiment, the drive assembly 20 includes a motor 21, a drive shaft 22, and a drive gear 23. In this embodiment, the drive gear 23 is sleeved on the drive shaft 22, and the drive gear 23 meshes with the inner gear 11. The drive shaft 22 is connected to the motor 21, so that the motor 21 can drive the drive shaft 22 to rotate, and cause the drive gear 23 to drive the inner gear 11 to rotate synchronously, so as to realize the rotation of the connector body 10 relative to the milk collection tube 30 and the milk cart connector 400. At the same time, under the action of the threaded part 12, the connector body 10 can move spirally along the direction from the milk collection tube 30 to the milk cart connector 400 until the milk collection tube 30 and the milk cart connector 400 are connected, so as to achieve the purpose of automatic connection and milk collection.
[0055] Optionally, the drive shaft 22 and the drive gear 23 are arranged in a one-to-one correspondence, and in this embodiment, there are three of each. The three drive shafts 22 are driven by three motors 21 respectively, and are evenly distributed on the outside of the milk collection tube 30, corresponding to the solute channel 104. Figure 10 As shown, the three transmission gears 23 are evenly arranged along the circumference of the inner gear teeth 11 to ensure the stability of the force on the inner gear teeth 11 and enable stable helical movement. Combined with... Figure 4 As shown, in this embodiment, along the axial direction of the connector body 10, the thickness of the transmission gear 23 is less than the length of the inner gear tooth 11, so as to ensure that the transmission gear 23 and the inner gear tooth 11 are always meshed when the connector body 10 moves, thus ensuring the power input of the connector body 10.
[0056] Furthermore, the drive shaft 22 passes through the receiving channel 104 to ensure stable rotation of the drive shaft 22 and to prevent interference with the movement of the drive shaft 22 when the connector body 10 rotates or moves relative to the milk collection tube 30. Figure 9 As shown, for example, a sensing contact 221 is provided at the end of the drive shaft 22 away from the motor 21. When the telescopic component 13 is retracted into the receiving groove 105, the second spherical surface 133 contacts the sensing contact 221, and at this time the motor 21 is started by mechanical transmission to drive the drive shaft 22 to rotate, so that the connector body 10 moves spirally.
[0057] like Figure 11 As shown, in this embodiment, the milk collection tube 30 is provided with a metal tube 31 and a rubber hose 32. Optionally, the two metal tubes 31 are located at both ends of the rubber hose 32, and are used to connect the connector body 10 and the milk tank, respectively. That is, the metal tube 31 is provided with a first threaded end 311, and is screwed to the threaded portion 12 through the first threaded end 311. Figure 4As shown, exemplarily, the outer diameter of the first threaded end 311 is larger than the outer diameter of the metal tube 31, and the ball ring 14 is sleeved on the outside of the metal tube 31. The lower limit of the first threaded end 311 under the action of the stepped surface between the threaded portion 12 and the communicating cavity 102 is located inside the threaded portion 12. When the connector body 10 moves along the direction from the milk collection tube 30 to the milk cart connector 400, the stepped surface can limit the first threaded end 311, preventing the connector body 10 from separating from the milk collection tube 30. Exemplarily, in this embodiment, the inner wall of the rubber hose 32 is smooth and spiral-shaped in its natural state, thereby ensuring smooth milk delivery and allowing the milk collection tube 30 to extend and retract, so that the extension length of the milk collection tube 30 can be controlled as needed when connecting it to the milk cart later. Furthermore, both ends of the rubber hose 32 are sealed to the metal tube 31 to prevent milk leakage.
[0058] Combination Figures 4-6 As shown, in this embodiment, in the initial state, the transmission gear 23 is located at the leftmost end of the inner gear tooth 11 near the connecting cavity 102, and the first threaded end 311 is located at the leftmost end of the threaded portion 12 facing the milk outlet 103, to ensure the maximum range of movement of the connector body 10. At this time, the telescopic component 13 extends out, and there is no contact between the telescopic component 13 and the transmission shaft 22. When the milk cart connector 400 is placed in the connector body 10, the second threaded end 410 will press against the telescopic component 13, causing it to compress within the receiving groove 105 and contact the transmission shaft 22, thereby activating the motor 21. The motor 21 drives the transmission shaft 22 to rotate, and the rotation of the connector body 10 is achieved under the meshing action of the transmission gear 23 and the inner gear tooth 11, so that the connector body 10 can move axially toward the milk cart connector 400. For example, the outer diameter of the second threaded end 410 of the milk cart connector 400 is larger than the pipe diameter of the milk cart connector 400, and the sum of the thickness of the second threaded end 410 and the thickness of the first threaded end 311 is less than the length of the threaded portion 12. Thus, after the connector body 10 moves to the second threaded end 410 and is fully screwed into the threaded portion 12, it loses its pressure on the telescopic component 13. Under the action of its elastic element 135, the telescopic component 13 returns to its initial state and extends out of the receiving groove 105, thereby shutting off the motor 21. At this time, the drive shaft 22 no longer rotates, and the connector body 10 no longer moves, thus completing the connection between the milk collection tube 30 and the milk cart connector 400 for milk collection. Furthermore, reversing the motor 21 allows the milk cart connector 400 to be detached, thereby avoiding manual operation, realizing automated and intelligent connection, and improving connection efficiency.
[0059] The specific structure of the automatic milk collection tube connection device in this embodiment will be described below.
[0060] like Figure 1 and Figure 2As shown, the automatic milk collection tube connection device in this embodiment includes the aforementioned connecting tube connector, clamp 210, three-axis displacement adjustment assembly, and telescopic rod 300. Optionally, the connecting tube connector is fixed in the clamp 210, the clamp 210 is disposed on the three-axis displacement adjustment assembly, and the telescopic rod 300 is telescopically connected to the three-axis displacement adjustment assembly. The milk collection tube 30 in the connecting tube connector is wound around the telescopic rod 300. Thus, through the cooperation of the three-axis displacement adjustment assembly and the telescopic rod 300, the connecting tube connector can be driven to move in the X, Y, and Z axis directions, thereby approaching the milk cart and precisely docking with the milk cart connector 400. Specifically, each pair of the X, Y, and Z axes is perpendicular to the others.
[0061] Specifically, the three-axis displacement adjustment assembly includes a Z-axis guide rail 220, an X-axis crossbeam 230, a vertical beam, and a Y-axis track. Optionally, the clamp 210 is slidably mounted on the Z-axis guide rail 220 along the Z-axis direction, thereby enabling the connecting pipe joint to move in the Z-axis direction under the action of the clamp 210. Further, the Z-axis guide rail 220 is slidably mounted on the X-axis crossbeam 230 along the X-axis direction, thereby enabling the connecting pipe joint to move in the X-axis direction when the Z-axis guide rail 220 moves on the X-axis crossbeam 230. Optionally, the telescopic rod 300 is vertically connected to the side of the X-axis beam 230 away from the connecting pipe joint along the Y-axis direction, and two vertical beams are set at both ends of the X-axis beam 230 along the Z-axis direction. The two vertical beams are slidably set on the Y-axis track along the Y-axis direction. Thus, under the telescopic effect of the telescopic rod 300 and the sliding connection effect between the vertical beams and the Y-axis track, the connecting pipe joint can be moved in the Y-axis direction, thereby achieving the ability of the connecting pipe joint to move in the X-axis, Y-axis and Z-axis directions.
[0062] Specifically, in this embodiment, the two vertical beams are a first vertical beam 241 and a second vertical beam 242, and the Y-axis track is provided with a Y-axis drive track 251 and a Y-axis driven track 252. Specifically, the end of the first vertical beam 241 facing away from the X-axis crossbeam 230 is sleeved on the Y-axis drive track 251 and slidably connected to the Y-axis drive track 251. The second vertical beam 242 is inserted into and confined in the Y-axis driven track 252 and slidably connected to the Y-axis driven track 252. Thus, when the first vertical beam 241 moves along the Y-axis on the Y-axis drive track 251, it can drive the second vertical beam 242 to move synchronously in the Y-axis driven track 252.
[0063] Furthermore, in this embodiment, the telescopic rod 300 is provided with at least a first rod section 310, a second rod section 320, and a third rod section 330, all of which can extend and retract within the first rod section 310, thereby achieving the telescopic effect of the telescopic rod 300. For example, the rubber hose 32 of the milk collection tube 30 is wound around the outside of the telescopic rod 300, thereby preventing wear on the milk collection tube 30 during movement while ensuring that the connecting pipe joint can move in the Y-axis direction to approach the milk cart.
[0064] For example, the three-axis displacement adjustment component can be connected to the central control system. After the milk truck enters the designated milk collection route, the three-axis displacement adjustment component performs one-to-one positioning with the milk truck connector 400, aligning the milk outlet 103 of the connector body 10 with the milk truck connector 400. Then, the milk hopper is connected to the milk collection pipe 30, and connected to the milk truck connector 400 via a connecting pipe connector. After automatic docking, milk collection is initiated via the central control system. After milk collection is completed, the connecting pipe connector is reversed to remove the milk truck connector 400, allowing the milk truck to proceed to the next workstation. Furthermore, connecting the connecting pipe connector to the cleaning circuit allows for cleaning of the emptied pipes and the inside of the milk hopper. The entire process requires no manual operation, and the automatic connection effectively improves milk unloading efficiency.
