[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figure 1 - Figure 5This utility model provides the following technical solution: a continuous filling and dispensing device for boxed liquids in food production, comprising a support frame 1 horizontally placed on the ground, symmetrically distributed support plates 2 fixedly connected to both sides of the top of the support frame 1, a moving frame 3 vertically slidably connected between the two support plates 2, a transport structure for driving the box to move installed inside the support frame 1, and an opening device installed at the output end of the top of the transport structure; Figure 4 As shown, the motion frame 3 has a filling structure installed inside. The filling structure includes a main liquid supply pipe 4, with equidistantly distributed output ends at the bottom of the main liquid supply pipe 4. Each output end is fixedly connected to a diversion pipe 5. A temporary storage tank 6 is fixedly connected to the outside of the diversion pipe 5. A pressurization chamber 10 is formed between the outside of the diversion pipe 5 and the inside of the temporary storage tank 6. A piston ring 11 is slidably connected inside the pressurization chamber 10. A double-layer corrugated sleeve 12 is fixedly connected to the top of the piston ring 11. The lower end of the diversion pipe 5 has a drain hole 7. Figure 5 As shown, an isolation plate 8 is fixedly connected to the outer side of the lower end of the diversion pipe 5. The isolation plate 8 is located at the top of the drain hole 7. The isolation plate 8 divides the interior of the temporary storage tank 6 into a storage chamber 9 and a pressurization chamber 10. The storage chamber 9 is located at the bottom of the pressurization chamber 10. The drain hole 7 is fixedly connected to the lower inner side of the temporary storage tank 6. The connection between the drain hole 7 and the temporary storage tank 6 is a hollow structure. An electric control valve 15 is provided at the bottom of the temporary storage tank 6. The electric control valve 15 is connected to the storage chamber 9. The piston ring 11 is slidably connected to the diversion pipe. Outside the pipe 5, the corrugated sleeve 12 located on the inner side is fitted on the outside of the diversion pipe 5. The double-layer corrugated sleeve 12 and the top of the piston ring 11 form a cavity. The diversion pipe 5 is connected to the liquid supply equipment. The diversion pipe 5 is controlled by an electric valve. The top of the temporary storage tank 6 is fixedly connected to a pressure ring 13. The bottom of the pressure ring 13 is connected to the cavity formed by the double-layer corrugated sleeve 12 and the top of the piston ring 11. The pressure ring 13 is provided with a connecting pipe 14, which is connected to the air compressor.
[0026] The support frame 1 is placed horizontally on the ground to provide a stable foundation. The support plates 2 are fixedly connected to the top two sides of the support frame 1 to form symmetrically distributed stable support points. The motion frame 3 is vertically slidably connected between the two support plates 2. The height is adjusted in the vertical direction by the hydraulic cylinder to adapt to the filling needs of boxes of different sizes. The transport structure installed inside the support frame 1 is responsible for driving the box to move along a predetermined path. The box opening device is fixedly installed at the output end of the top of the transport structure to automatically open the box lid and ensure that the box is in an open state during the filling process.
[0027] The box-opening device automatically applies force to the box lid, opening the box body to prepare for subsequent filling. At the same time, the main liquid supply pipe 4 in the filling structure receives liquid food by connecting to an external liquid supply device. The bottom of the main liquid supply pipe 4 has multiple equidistant output ends, each of which is fixedly connected to a diversion pipe 5. The outer side of the diversion pipe 5 is fixedly connected to a temporary storage tank 6. Liquid flows from the main liquid supply pipe 4 into the diversion pipe 5 and is then distributed to each temporary storage tank 6. The design of the temporary storage tank 6 includes the space formed by the inner and outer sides. The partition plate 8 is fixedly connected to the outer side of the lower end of the diversion pipe 5 and is located at the top of the drain hole 7. The partition plate 8 divides the interior of the temporary storage tank 6 into an upper liquid storage chamber 9 and a lower pressurization chamber 10. The liquid storage chamber 9 is used to temporarily store liquid, and the pressurization chamber 10 is used to apply pressure to promote liquid flow.
[0028] After the liquid flows into the diversion pipe 5, it passes through the isolation plate 8 and enters the storage chamber 9. The piston ring 11 on the outside of the diversion pipe 5 is slidably connected to the inside of the pressurization chamber 10. The double-layer corrugated sleeve 12, which is fixedly connected to the top of the piston ring 11, is fitted onto the outside of the diversion pipe 5 to form a closed structure. The double-layer corrugated sleeve 12 and the top of the piston ring 11 together form a cavity. This cavity is fixedly connected to the top of the temporary storage tank 6 through the pressurization ring 13. The pressurization ring 13 is provided with a connecting pipe 14, which is connected to an external air compressor. When the external air compressor is connected through the connecting pipe 14... When compressed air is injected into the cavity, the cavity expands, pushing the double-layer corrugated sleeve 12 and piston ring 11 downward. The displacement of piston ring 11 creates positive pressure in the pressurization chamber 10, squeezing the liquid in the storage chamber 9. The drain hole 7 below the storage chamber 9 is fixedly connected to the lower inner side of the temporary storage tank 6. The connection between the drain hole 7 and the temporary storage tank 6 is a hollow structure, allowing the liquid to pass through smoothly. The electric control valve 15 is fixedly connected to the bottom of the temporary storage tank 6 and communicates with the storage chamber 9. The electric control valve 15 is operated by the control system to regulate the flow of liquid from the drain hole 7.
[0029] During the filling process, the motion frame 3 adjusts the height of the filling structure by vertical sliding to ensure that the electric control valve 15 at the bottom of the diversion pipe 5 is aligned with the opening position of the box. When the box moves to the filling point through the transport structure, the electric control valve 15 opens, and the pressure applied by the pressurization chamber 10 pushes the liquid in the storage chamber 9 to be quickly discharged through the drain hole 7, achieving high-speed filling. Once the filling volume reaches the preset value based on the time or flow sensor signal, the electric control valve 15 closes, the liquid stops flowing out, and the air compressor stops supplying air. The piston ring 11 resets under the action of the spring or gravity inside the system, waiting for the next cycle. The whole process is continuous. The transport structure ensures the continuous movement of the box, and the box opening device and the filling structure work together to ensure seamless connection between the opening and filling of each box. The diversion design of the filling structure allows multiple boxes to be processed at the same time, increasing production capacity.
[0030] Example 2: Based on Example 1, please refer to... Figure 2 and Figure 6The following structure is also disclosed: the transport structure includes drive rollers 16 rotatably connected inside the support frame 1 and symmetrically distributed. The drive rollers 16 are driven by servo motors. A chain plate structure is sleeved on the outside of the two drive rollers 16. The chain plate structure is composed of bearing plates 17 that are hinged to each other at both ends. Figure 6 As shown, symmetrically distributed guide rails 18 are fixedly connected to the outer side of the bearing plate 17. Two symmetrically distributed clamping blocks 19 are slidably connected inside the two guide rails 18. A connecting rod is fixedly connected to the bottom center of each clamping block 19. A synchronous turntable 20 is rotatably connected to the bottom center of the bearing plate 17. A torsion spring is provided between the synchronous turntable 20 and the bottom of the bearing plate 17. The connecting rod at the bottom of each clamping block 19 is rotatably connected to the side of the synchronous turntable 20 through a swing arm to form a synchronous structure.
[0031] Two drive rollers 16 are fitted with chain plate structures on their outer sides. The chain plate structure consists of bearing plates 17 that are hinged together end to end, allowing flexible bending to adapt to changes in the path. Symmetrically distributed guide rails 18 are fixedly connected to the outer side of the bearing plates 17. Two symmetrically distributed clamping blocks 19 are slidably connected inside the two guide rails 18. A connecting rod is fixedly connected to the bottom center of each clamping block 19. A synchronous turntable 20 is rotatably connected to the bottom center of the bearing plate 17. A torsion spring is provided between the synchronous turntable 20 and the bottom of the bearing plate 17 to provide restoring force. The connecting rod at the bottom of each clamping block 19 is rotatably connected to the side of the synchronous turntable 20 through a swing arm to form a synchronous structure, realizing the symmetrical movement of the clamping blocks and ensuring that the box is evenly clamped during movement.
[0032] The overall operation of the device begins with the drive of the transport structure. The servo motor drives the drive roller 16 to rotate, which transmits the power to the outer chain plate structure. The carrier plate 17 moves along the predetermined track under the drive roller 16. Each carrier plate 17 acts as a moving platform, carrying the box through the device path. When the box is placed on the carrier plate 17, the symmetrically distributed guide rails 18 allow the clamping blocks 19 to slide horizontally. The connecting rod at the bottom of the clamping block 19 is connected to the synchronous turntable 20 through the swing arm. The synchronous turntable 20 maintains its initial position under the action of the torsion spring. The torsion spring accumulates energy when the synchronous turntable 20 rotates, providing a self-resetting function. It pushes the box towards the center through the connecting rod, synchronously clamping both sides of the box. Since all the clamping blocks 19 are uniformly connected to the side of the synchronous turntable 20 through the swing arm, any rotation of the synchronous turntable 20 drives all the clamping blocks 19 to move synchronously, ensuring that the clamping action is symmetrical and consistent, preventing the box from shifting or tipping over. The torsion spring maintains pressure after clamping to prevent loosening.
[0033] The main liquid supply pipe 4 distributes liquid to the temporary storage tank 6 through the diversion pipe 5. The pressure ring 13 and the connecting pipe 14 introduce the air compressor pressure, which acts on the liquid storage chamber 9 through the piston ring 11 and the double-layer corrugated sleeve 12. The electric control valve 15 controls the liquid filling. The clamping structure ensures that the box is fixed and does not move during filling, improving filling accuracy. After filling is completed, the synchronous turntable 20 is driven to reset by the torsion spring after completing the action. The swing arm release link and the clamping block 19 returns to its original position along the guide rail 18, releasing the box. The box continues to move downstream with the chain plate structure.
