Description

Technical Field

[0001] This utility model relates to the technical field of batching equipment for liquid flavor production, and in particular to an automatic batching device for liquid flavor production. Background Technology

[0002] Compared to natural flavorings, synthetic liquid flavorings are cheaper and more widely used. To approximate the taste of natural flavorings, synthetic liquid flavorings require mixing various raw materials in a specific ratio. The mixing process typically involves manually weighing the raw materials and then mixing them in a mixing tank. This process not only increases the workload for operators but also introduces the risk of weighing errors and insufficient mixing, leading to variations in the taste of the finished liquid flavoring and making it difficult to maintain consistent quality.

This automatic batching device replaces manual weighing and mixing of liquid flavorings, thereby improving batching efficiency and the consistency of the quality of finished liquid flavoring products.

[0004] The objective of this utility model is achieved through the following technical solution:

Detailed Implementation

[0038] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] See Figures 1 to 14 This embodiment relates to an automatic batching device for liquid flavor production, including a support 1, a raw material tank 2 disposed on the support 1 for storing liquid flavor raw materials, a mixing tank 3 located below the raw material tank 2 for mixing liquid flavor raw materials, and a feeding pipe 4 connecting the raw material tank 2 and the mixing tank 3; the raw material tank 2 has an annular side wall, a top wall and a bottom wall, and the mixing tank 3 has an annular side wall, a top wall and a bottom wall.

[0040] Raw material tank 2 has a feeding port on its top wall and a tank cover 5 at the feeding port. Raw material tank 2 also has a discharge port on its bottom wall and a first switching valve 6 at the discharge port. Mixing tank 3 has a feeding inlet on its top wall and a second switching valve 7 at the feeding inlet. Mixing tank 3 has a discharge outlet on its bottom wall and a third switching valve 8 at the discharge outlet. A stirring mechanism is installed inside mixing tank 3, and a drive unit connected to the stirring mechanism is installed outside mixing tank 3. One end of the feeding pipe 4 is connected to the first switching valve 6 at the discharge port of raw material tank 2, and the other end of the feeding pipe 4 is connected to the second switching valve 7 at the feeding inlet of mixing tank 3. When the first switching valve 6 is open, the liquid flavoring raw material in raw material tank 2 can enter the feeding pipe 4; when the second switching valve 7 is open... An internal weighing device is installed. The weighing device is used to weigh the liquid flavoring raw material entering the feeding pipe 4 when the second switch valve 7 is closed. The weight value obtained by the weighing device is transmitted to an external control terminal via wired or wireless means. When the weight of the liquid flavoring raw material entering the feeding pipe 4 reaches a preset threshold, the control terminal controls the first switch valve 6 to close to stop the input of liquid flavoring raw material into the feeding pipe 4, and then controls the second switch valve 7 to open so that the weighed liquid flavoring raw material can enter the mixing tank 3 and be stirred and mixed into a finished liquid flavoring product by the stirring mechanism. After stirring and mixing, the third switch valve 8 is controlled to open so that the finished liquid flavoring product can be discharged from the bottom of the mixing tank 3 through the discharge port and loaded and transferred by the transfer equipment located below the mixing tank 3.

[0041] It should be noted that the three switching valves in this embodiment can be manually switched or switched using an external control terminal. Compared to manual switching, the control terminal has a higher degree of automation and reduces the labor intensity of operators. In this embodiment, the transfer equipment can be a tank truck as in the prior art. The tank truck is driven to the bottom of the mixing tank 3, and the tank opening on the tank truck is connected to the third switching valve 8 at the discharge port of the mixing tank 3 through a connecting pipe, so that the tank truck can load the liquid flavoring product and transfer it to the packaging workshop for packaging. Depending on the actual situation, a screw conveyor as in the prior art can also be used. The input end of the screw conveyor is connected to the third switching valve 8 at the discharge port of the mixing tank 3 through a connecting pipe, and the output end of the screw conveyor extends to the input port of the packaging equipment. The liquid flavoring product is transferred to the packaging equipment for packaging through the screw conveyor. The tank truck is suitable for long-distance or multi-packaging workshop transfer, while the screw conveyor is suitable for short-distance or single-packaging workshop transfer. Those skilled in the art can select the appropriate transfer equipment according to the actual situation. Both the tank truck and the screw conveyor are conventional transfer equipment, and their structures will not be described in detail here.

[0042] Specifically, in this embodiment, the support 1 is a frame structure, made of multiple connecting rods welded together. In this embodiment, the connecting rods are I-beams. The support 1 is provided with a first layer plate 9, a second layer plate 10, and a third layer plate 11 arranged sequentially from top to bottom along the height direction. The three layers are arranged at intervals. The raw material tank 2 is fixedly installed on the first layer plate 9, and a first clearance hole is opened on the first layer plate 9 that is opposite to the discharge port on the raw material tank 2. The driving component is fixedly installed on the second layer plate 10, and a second clearance hole is opened on the second layer plate 10 that is opposite to the feed port on the mixing tank 3. The driving end of the driving component can pass through the second layer plate 10. The third clearance hole of the drive connection to the stirring mechanism; the mixing tank 3 is fixedly installed on the third layer plate 11, and a fourth clearance hole is opened on the third layer plate 11 opposite to the discharge port on the mixing tank 3. The space between the third layer plate 11 and the ground is formed so that a storage tank truck can drive in or a transfer equipment such as a screw conveyor can be connected to facilitate the transfer of liquid flavoring products; the feeding pipe 4 is located between the first layer plate 9 and the second layer plate 10. The upper end of the feeding pipe 4 is connected to the discharge port on the raw material tank 2 through the first switch valve 6 at the first clearance hole, and the lower end of the feeding pipe 4 is connected to the inlet on the mixing tank 3 through the second switch valve 7 at the second clearance hole.

[0043] In this embodiment, four raw material tanks 2 are provided, and the four raw material tanks 2 are arranged at equal intervals around the center of the first layer plate 9. The first clearance hole on the first layer plate 9 is also provided accordingly. The number of raw material tanks 2 can be increased or decreased according to the actual situation. Each raw material tank 2 can store one type of liquid flavoring raw material. Therefore, in this embodiment, four types of liquid flavoring raw materials can be stored separately. At the same time, four feeding pipes 4 are provided, and four first switching valves 6, second switching valves 7 and weighing devices are respectively configured on the four raw material tanks 2, so that the liquid flavoring raw materials in the four raw material tanks 2 are weighed by the weighing device in the four feeding pipes 4 and then fed into the mixing tank 3 for mixing and stirring, so as to meet the liquid flavoring ingredient requirements of different raw material ratios.

[0044] The raw material tank 2 has a hollow cylindrical structure, forming an internal storage chamber for containing liquid flavoring raw materials. The feeding port on the top wall and the discharge port on the bottom wall of the raw material tank 2 connect to this storage chamber. The tank lid 5 is a circular lid that covers the feeding port of the raw material tank 2 to seal the storage chamber, preventing outside air from entering the raw material tank 2 and accelerating the oxidation and deterioration of the liquid flavoring raw materials, thereby extending the shelf life of the liquid flavoring raw materials. In this embodiment, the raw material tank 2 has at least three first support legs 1 arranged at equal intervals around the center of the raw material tank 2 at its bottom. 2; The first layer plate 9 is provided with at least three support seats 13 around each first clearance hole. The support seats 13 are matched one-to-one with the first support feet 12 to detachably install the raw material tank 2 on the first layer plate 9, so that the first switch valve 6 at the discharge port of the installed raw material tank 2 can be connected to the upper end of the feeding pipe 4. When disassembling and assembling the raw material tank 2, the gantry crane set on the top of the workshop can be used to lift the raw material tank 2. Depending on the actual situation, other existing lifting equipment can also be used to lift the raw material tank 2.

[0045] In this embodiment, the first support leg 12 is a cylindrical rod structure; the support base 13 is a hollow cylindrical base structure with an insertion chamber inside and an insertion hole at the top that connects to the insertion chamber, so that the first support leg 12 can be inserted into the support base 13 when the raw material tank 2 is installed; a clamping member is provided inside the support base 13, which is used to clamp and fix the first support leg 12 inserted into the support base 13.

[0046] The clamping element is a tapered sleeve 14 whose diameter gradually decreases from top to bottom. The tapered sleeve 14 has a conical outer circumferential surface and forms a clamping cavity in the middle. At least two contraction grooves 14a are provided on the tapered sleeve 14, and the contraction grooves 14a are arranged at equal intervals around the axis. The insertion chamber inside the support base 13 is a tapered cavity whose diameter gradually decreases from top to bottom, and the inner wall surface of the insertion chamber is a wedge-shaped surface. When the first support foot 12 is inserted into the tapered sleeve 14, the outer circumferential surface of the tapered sleeve 14 fits against the inner wall surface of the insertion chamber to form a radial force. As the first support foot 12 continues to be inserted... The radial force causes the conical sleeve 14 to move downwards. Under this radial force, the conical sleeve 14 radially contracts and clamps the first support foot 12, thereby clamping the first support foot 12, reducing shaking, and ensuring the installation stability of the raw material tank 2. A seat cover 15 is detachably provided at the top insertion hole of the support base 13. The seat cover 15 is used to confine the conical sleeve 14 in the insertion chamber to prevent the first support foot 12 from taking the conical sleeve 14 out of the support base 13 when disassembling or assembling the raw material tank 2. The seat cover 15 has a through hole through which the first support foot 12 can pass. The diameter of the through hole is smaller than the top outer diameter of the conical sleeve 14.

[0047] The feeding pipe 4 is a retractable circular tube with a wavy annular wall for easy expansion and contraction. A first docking ring 16 is provided at the upper end of the feeding pipe 4, which docks with the first switching valve 6. A second docking ring 17 is provided at the lower end of the feeding pipe 4, which docks with the second switching valve 7 and is bolted to the second clearance hole of the second layer plate 10 after docking. A lifting mechanism is provided on the second layer plate 10, which drives the first docking ring 16 at the upper end of the feeding pipe 4 to dock with or separate from the first switching valve 6. A locking mechanism is provided between the first docking ring 16 and the first switching valve 6, which locks the first docking ring 16 after docking. Preferably, in this embodiment, the feeding pipe 4, the first docking ring 16, and the second docking ring 17 are integrally formed, effectively avoiding gaps at the connection point and thus preventing leakage of liquid flavoring raw materials.

[0048] The lifting mechanism includes a lifting plate 18 and an electric lead screw 19 that can drive the lifting plate 18 to rise and fall. The lifting plate 18 has a pipe hole through which a feeding pipe 4 can pass. Two interlocking clamping plates 20 are provided at the pipe hole on the lifting plate 18, and clamping grooves are provided on the mating surfaces of the two clamping plates 20. A first bolt hole 21 is provided on the clamping plate 20. The clamping plate 20 is fixed to the lifting plate 18 by inserting a first bolt into the first bolt hole 21. In this embodiment, the first bolt hole 21 is an elongated hole to facilitate adjustment of the position of the clamping plate 20. The clamping plate 20 has a second bolt hole on both sides of the clamping groove. Two bolt holes 22 are used to lock the two spliced ​​clamping plates 20 by inserting second bolts into the second bolt holes 22. During splicing, the inner wall surface of the clamping groove of the two clamping plates 20 is in contact with the outer periphery of the first docking ring 16 to form a clamping force, thereby clamping and fixing the first docking ring 16 on the lifting plate 18. An elastic pad (not shown in the figure) is provided on the inner wall surface of the clamping groove to increase the clamping force on the first docking ring 16. In this embodiment, two clamping plates 20 are used as clamping rings. Depending on the actual situation, other clamping rings suitable for clamping the first docking ring 16 can also be used instead.

[0049] The lifting plate 18 has four guide rod holes 31 evenly spaced around the pipe hole. A guide rod 23 is movably inserted into each guide rod hole 31. The top end of the guide rod 23 is connected to the first layer plate 9, and the bottom end of the guide rod 23 is connected to the second layer plate 10. The electric screw 19 has a motor part and a screw part. The motor part of the electric screw 19 is installed on the bottom surface of the second layer plate 10. The screw part of the electric screw 19 passes through the second layer plate 10 and the lifting plate 18 from bottom to top and is rotatably connected to the bottom surface of the first layer plate 9. A screw seat that can cooperate with the top end of the screw part of the electric screw 19 is provided on the bottom surface of the first layer plate 9. The second layer plate 10 has a through hole through which the screw part of the electric screw 19 can pass; the screw part of the electric screw 19 is threaded with a screw nut, which is connected to the bottom surface of the lifting plate 18; when the screw part of the electric screw 19 rotates, the axial movement of the screw nut drives the lifting plate 18 to rise and fall, thereby driving the first docking ring 16 on the feeding pipe 4 to dock or separate from the first switching valve 6; in this embodiment, four electric screws 19 are provided and are arranged at equal intervals around the pipe hole on the lifting plate 18, so as to apply force evenly to the lifting plate 18 and improve the lifting stability of the lifting plate 18.

[0050] The locking mechanism includes a first annular docking portion 16a disposed on the first docking ring 16, a locking ring 24 rotatably disposed on the first annular docking portion 16a, a second annular docking portion 6a disposed on the docking end of the first switch valve 6, and an actuator disposed on the lifting plate 18 that can drive the locking ring 24 to connect with the first annular docking portion 16a; the first annular docking portion 16a and the second annular docking portion 6a are respectively provided with docking grooves and docking flanges that can cooperate with each other during docking, so as to facilitate the rapid axial docking of the first docking ring 16 and the first switch valve 8; the first annular docking portion 16a has a smooth outer peripheral surface and an annular flange is provided on the outer side of the top end, and the locking ring 24... 4 is rotatably fitted onto the first annular mating part 16a, and has an inner edge at the bottom inner hole that can cooperate with the annular flange to prevent the locking ring 24 from disengaging from the first annular mating part 16a; the second annular mating part 6a has an external thread on the outer side, the locking ring 24 has an internal thread on the inner side, the locking ring 24 has a driven engagement part on the outer side, and the actuator has an active engagement part that can engage with the driven engagement part on the locking ring 24. The actuator drives the locking ring 24 to rotate relative to the first annular mating part 16a so that the locking ring 24 is threadedly connected to the second annular mating part 6a, thereby locking the first mating ring 16 and the first switch valve 6.

[0051] In this embodiment, the actuator 25 is a motor in the prior art. The motor is fixedly installed on the top surface of the lifting plate 18. The output shaft of the motor is vertically upward and connected to a drive gear. The drive teeth on the circumferential surface of the drive gear serve as the drive engagement part. The locking ring 24 has driven teeth on its outer circumferential surface as the driven engagement part. The drive teeth on the drive gear and the driven teeth on the locking ring 24 mesh with each other to transmit the driving force generated when the motor starts to the locking ring 24, so that the locking ring 24 can rotate to complete the locking.

[0052] When the first docking ring 16 and the first switching valve 6 separate, the locking ring 24 slides downward under its own weight until its bottom surface contacts the docking surface of the first docking ring 16. When the first docking ring 16 and the first switching valve 6 dock, the top of the locking ring 24 contacts the second annular docking portion 6a on the first switching valve 6, so that the locking ring 24 can be threadedly connected to the second annular docking portion 6a when driven by the actuator 25, and can move axially relative to the first annular docking portion 16a. When the inner edge of the locking ring 24 is stopped by the annular flange on the first annular docking portion 16a, the locking ring 24 is locked. It should be noted that the thickness of the driving gear should be greater than the axial movement stroke of the locking ring 24 so that the driving teeth on the driving gear and the driven teeth on the locking ring 24 can maintain meshing transmission.

[0053] In this embodiment, when replacing the raw material tank 2, a lifting mechanism is used to replace manual labor in connecting or separating the first switch valve 6 and the first docking ring 16, and a locking mechanism is used to replace manual labor in locking or unlocking the first switch valve 6 and the first docking ring 16, thereby achieving rapid disassembly and assembly of the raw material tank 2 and the feeding pipe 4. Moreover, since the electric screw 19 and the actuator 25 are connected to an external control terminal via a cable, when the raw material tank 2 needs to be replaced, the control terminal can control the electric screw 19 and the actuator 25 to start, which can realize the connection, separation and locking of the first switch valve 6 and the first docking ring 16, and can significantly reduce the labor intensity of the operators.

[0054] The mixing tank 3 has a hollow cylindrical tank structure, forming a mixing chamber inside to accommodate the stirring mechanism. The inlet on the top wall and the outlet on the bottom wall of the mixing tank 3 are connected to the mixing chamber. The mixing tank 3 has at least three second support legs 26 arranged at equal intervals around the center of the mixing tank 3. The second support legs 26 are cylindrical structures. The top of the second support legs 26 are welded and fixed to the bottom wall of the mixing tank 3, and the bottom of the second support legs 26 are fixedly connected to the top surface of the third layer plate 11 by bolts. The outlet is located at the center of the bottom wall of the mixing tank 3. The bottom wall of the mixing tank 3 is a cone shape that gradually decreases from top to bottom, so that the liquid flavoring product can flow along the inner surface of the bottom wall of the mixing tank 3 under its own weight to the outlet for centralized discharge, thereby reducing the liquid flavoring product residue at the bottom of the mixing tank 3.

[0055] The stirring mechanism includes a stirring shaft 27 and stirring blades 28 disposed on the stirring shaft 27. The top end of the stirring shaft 27 extends rotatably out of the top wall of the mixing tank 3 and is connected to the driving end of the driving component. A gap is formed between the bottom end of the stirring shaft 27 and the bottom wall of the mixing tank 3 to avoid contact and friction between the stirring shaft 27 and the bottom wall of the mixing tank 3 when rotating. In this embodiment, two stirring blades 28 are provided. The number of stirring blades 28 can be increased according to the actual situation. The stirring blades 28 are arranged at equal intervals around the stirring shaft 27. The stirring blades 28 are rectangular frames, including two parallel horizontal bars and a vertical bar connecting one end of the two horizontal bars. The other end of the two horizontal bars is connected to the outer circumferential surface of the stirring shaft 27. When the driving component is started, it drives the stirring shaft 27 to rotate, which in turn drives the stirring blades 28 to rotate accordingly to stir and mix the liquid flavoring raw materials. In this embodiment, the driving component is a servo motor 29 in the prior art. The servo motor 29 is connected to an external control terminal through a cable, and the start, stop and speed of the servo motor 29 are controlled by the external control terminal.

[0056] In this embodiment, the first switching valve 6, the second switching valve 7, and the third switching valve 8 are all solenoid valves with the same structure as those in the prior art, including a valve body and a piston disposed in the valve body. The valve body has an input end and an output end, and the piston has a material-facing surface and a material-returning surface. When the solenoid valve is closed, the material-facing surface of the piston faces the input end of the valve body to intercept the liquid flavoring raw material, and the material-returning surface faces the output end of the valve body. Among them, the second switching valve 7 has a weighing device fixedly installed on the material-facing surface of the piston, and the weighing device is a gravity sensor 30.

[0057] When the second switch valve 7 is closed, the liquid flavoring raw material is blocked in the feeding pipe 4 and weighed by the gravity sensor 30. The weight value obtained by the gravity sensor 30 is transmitted to the external control terminal via wired or wireless means. The control terminal controls the first switch valve 6 to gradually reduce the opening degree according to the obtained weight value, so as to gradually slow down the entry of the liquid flavoring raw material into the feeding pipe 4. When the weight of the liquid flavoring raw material entering the feeding pipe 4 reaches the preset threshold, the control terminal controls the first switch valve 6 to be completely closed. Then, the second switch valve 7 is controlled to open so that the weighed liquid flavoring raw material can enter the mixing tank 3 for stirring and mixing. After stirring and mixing, the third switch valve 8 is controlled to open so that the finished liquid flavoring product can be discharged from the bottom of the mixing tank 3 and transferred by the transfer equipment located below the mixing tank 3.

[0058] The automatic batching device in this embodiment can replace manual labor to weigh and mix liquid flavorings, thereby improving batching efficiency and the consistency of finished products; at the same time, it is equipped with a lifting mechanism and a locking mechanism, which can enable the raw material tank 2 and the feeding pipe 4 to be quickly disassembled and assembled.

[0059] In this embodiment, the control terminal is an industrial control computer (not shown in the figure) in the prior art. The industrial control computer includes a cabinet, a communicator and a PLC programmable logic controller installed in the cabinet, and a display installed on the cabinet. The communicator receives the weight value obtained by the gravity sensor 30 and transmits it to the PLC programmable logic controller. The PLC programmable logic controller sends action commands to the three switching valves through the communicator according to the weight value, so as to adjust the opening and closing state of the three switching valves respectively to complete the liquid flavoring preparation. When it is necessary to replace the raw material tank, the PLC programmable logic controller sends a command to the three switching valves through the communicator to complete the closure, and sends action commands to the electric screw 19 and the actuator 25 to drive the lifting mechanism and the locking mechanism to complete the corresponding actions, so that the first switching valve 6 and the feeding pipe are unlocked and separated, and the docking lock is restored after replacement.
