Description

Technical Field

[0001] This utility model relates to the field of spiral juicer technology, and in particular to a juicer that automatically separates juice from pulp. Background Technology

[0002] With the booming development of the fruit and vegetable powder market, industrial-grade juicers play a crucial role in fruit and vegetable powder production lines. Unlike household juicers, industrial-grade juicers need to meet the strict requirements of high efficiency, large-scale production, and continuous and stable production. Most existing industrial-grade juicers adopt the principle of spiral extrusion, which separates the juice from fruits and vegetables through the rotation and extrusion of the spiral rod.

[0003] In existing technologies, the spiral blades rely mainly on friction to push the fruit and vegetables when they come into contact with them. For some fruits and vegetables with smooth surfaces, hard textures, or irregular shapes, this gripping force is very limited. Moreover, the pressure regulation mostly depends on manual valves for opening control, which cannot achieve closed-loop feedback and precise pressure regulation. It is difficult to accurately control the pressure at the critical point that maximizes juice output without causing machine overload or blockage. Therefore, a juice and pulp self-separating juicer is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In order to address the technical problem that in the existing technology, the spiral blades have very limited gripping force when conveying fruits and vegetables with smooth surfaces, hard textures, or irregular shapes, and that the pressure regulation mostly relies on manual valves for opening control, making it difficult to accurately control the pressure at the critical point that maximizes juice output without causing machine overload or blockage, this application provides a juice and pulp self-separating juicer.

[0005] This utility model proposes a juicer with self-separating juice and pulp, which includes a frame and a juicing mechanism inside the frame. The juicing mechanism includes a screw rod, which conveys and squeezes fruits and vegetables through its structural features.

[0006] The frame is equipped with an adjustment mechanism, which includes an adjustment plate. The movement of the adjustment plate adjusts the slag discharge resistance at the end of the juicing chamber of the frame.

[0007] Preferably, the juicing mechanism further includes a motor, which is fixedly mounted on the bottom support plate of the frame, and the output shaft of the motor is rotatably connected to the bottom support plate of the frame through a bearing seat.

[0008] The above technical solution involves fixing the motor to the frame, with the motor's output shaft rotatably connected to the frame via a bearing housing, ensuring the stability of the motor's output shaft rotation. The motor model can be a DC brushless motor, which requires a power adapter and a BLDC motor driver / controller to achieve precise speed control, facilitating the setting of different speeds for different ingredients.

[0009] Preferably, the output shaft of the motor drives the screw rod to rotate via a synchronous belt, the screw rod is rotatably connected to the inner wall of the groove of the frame via a bearing, and a filter screen is fixedly installed inside the frame by bolts.

[0010] With the above technical solution, a main synchronous pulley is installed on the output shaft of the motor, and a secondary synchronous pulley is set at one end of the screw rod located outside the frame, so that the high-speed rotational power of the motor can be transmitted to the screw rod through the synchronous belt transmission system at a certain transmission ratio to drive its rotation. The screw rod is rotatably connected to the frame through bearings to ensure the stability of the screw rod rotation. The frame is fixed to the filter screen with bolts, which not only fixes it but also facilitates disassembly for subsequent cleaning. Both the screw rod and the filter screen can be made of 304 stainless steel, which has extremely high strength and durability and is not easily deformed. The input shaft of the screw rod passes through the hole in the frame where the skeleton oil seal is located. It consists of a metal skeleton, a spring, and a fluororubber or nitrile rubber sealing lip. A dust cover or labyrinth seal can be added to the outside of the skeleton oil seal to form double protection and further prevent contaminants from entering.

[0011] Preferably, the spiral rod is located inside the filter screen, and the outer ring of the spiral blades of the spiral rod has triangular serrations.

[0012] Through the above technical solution, a ring-shaped extrusion chamber is formed by the screw rod located inside the filter screen. The filter screen provides a solid boundary and reaction surface for extrusion, while the screw rod is the power source for generating extrusion force within this enclosed space. The close cooperation between the two forms the structural basis for achieving efficient solid-liquid separation. The screw rod is a variable-diameter screw rod; as the screw rod shaft diameter increases, the volume of the extrusion chamber gradually decreases from front to back, thus creating a gradual and increasing extrusion force on the fruits and vegetables. This achieves a gentle yet efficient juicing process, which is beneficial for increasing juice yield and preserving the nutritional value of the juice. The upper right side of the frame has a feeding frame where the operator pours the fruits and vegetables to be juiced into the frame. Triangular serrations are located on the outer ring of the initial two or three spiral blades on the screw rod, directly opposite the feeding inlet of the feeding frame. This area is the first stop for the fruits and vegetables entering the juicer. When the triangular serrations rotate, they act like high-speed rotations. The blade assembly forcibly grips, cuts, and tears the input fruits and vegetables, effectively preventing slippage and blockage of smooth or large pieces of fruit and vegetables, such as apples and carrots, at the feed inlet. This ensures a continuous and smooth feeding process. Before the fruits and vegetables enter the main extrusion zone, their cell structure has been initially damaged, greatly reducing the difficulty of subsequent extrusion. The fruit and vegetable juice flows through the discharge pipe with an electric valve under the frame. The rest of the screw adopts a variable diameter design. The pre-crushed fruit and vegetable materials are transported to this area. As the screw shaft diameter gradually increases from front to back, the volume of the extrusion chamber continuously decreases, thereby forming a gradual and increasing extrusion force on the material.

[0013] Preferably, the adjusting mechanism further includes an electric push rod, which is fixedly installed on the left side surface of the slag discharge frame of the frame.

[0014] The above technical solution involves fixing the electric push rod to the slag discharge frame of the frame. The electric push rod can be a DC electric push rod, which needs to be equipped with a relay or H-bridge drive circuit to control the forward and reverse rotation of the push rod motor, i.e., extension and retraction, controlled by the main control MCU. The extension rod of the electric push rod passes through the hole in the slag discharge frame of the frame and is sealed with a corrugated dust cover made of rubber or TPU material. One end of the cover is fixed to the hole in the frame, and the other end is fixed to the extension rod of the electric push rod. When the push rod extends and retracts, the corrugated tube will stretch and compress accordingly, forming a dynamic and flexible sealing barrier.

[0015] Preferably, a tension / compression sensor is fixedly installed at one end of the telescopic rod of the electric push rod, and one end of the tension / compression sensor is fastened to the outer side of the adjusting plate. An observation window is provided on the front surface of the slag discharge frame of the frame.

[0016] Through the above technical solution, one end of the telescopic rod of the electric push rod can be fixedly installed to the tension / compression sensor via a connecting flange. Once fixed, the electric push rod receives control signals and outputs precise linear thrust / tension, thereby driving the adjustment plate to move. The tension / compression sensor is fastened to the adjustment plate with high-strength bolts. The sensor measures in real time the reaction force from the fruit pulp on the adjustment plate, directly reflecting the pulp discharge resistance, and converts the force signal into an electrical signal, feeding it back to the control system. Driven by the electric push rod, the adjustment plate changes the size of the pulp outlet, thereby adjusting the juicing pressure. An S-type tension / compression sensor can be used. S-type sensors can measure both tension and pressure, have a wide measurement range, and high accuracy, making them ideal for installation between the push rod and the adjustment plate. A signal conditioning module / transmitter and a regulated power supply are required to provide the sensor with a precise excitation voltage, typically 10V or 12V. To ensure measurement accuracy, a viewing window is installed at the front of the slag discharge frame of the machine frame, allowing users to easily observe the slag discharge and the dryness and moisture content of the fruit pomace. The viewing window can be made of tempered glass or high-transparency polycarbonate, which meets food contact grade requirements and is resistant to high temperatures and impacts. A full-circle sealing gasket is added between the viewing window and the slag discharge frame. The material is food-grade silicone rubber or foamed silicone rubber. The viewing window and the sealing gasket are pressed tightly together onto the slag discharge frame using a pressure frame or flange, and then evenly tightened with bolts.

[0017] The beneficial effects of this utility model are as follows: 1. By setting up a juicing mechanism, fruits and vegetables are conveyed and squeezed. The high-speed rotation power of the motor is transmitted to the screw rod through a synchronous belt drive system at a certain transmission ratio, driving it to rotate. The screw rod is located inside the filter screen, forming an annular squeezing chamber. The filter screen provides a solid boundary and reaction force surface for squeezing, while the screw rod is the power source for generating squeezing force within this enclosed space. The close cooperation between the two is the structural basis for achieving efficient solid-liquid separation. Triangular serrations are set on the outer ring of the initial two or three spiral blades on the screw rod, directly opposite the feed inlet of the feed frame. This area is the first stop for fruits and vegetables entering the juicer. When rotating, the triangular serrations act like a high-speed rotating blade assembly, forcibly gripping, cutting, and tearing the input fruits and vegetables. This effectively prevents smooth or large pieces of fruits and vegetables from being squeezed, solving the technical problem in existing technologies where the spiral blades mainly rely on friction to push the fruits and vegetables when in contact, resulting in very limited gripping force for some smooth, hard, or irregularly shaped fruits and vegetables.

[0018] 2. By setting an adjustment mechanism, the pulp discharge resistance at the end of the juicing chamber of the frame is adjusted. The electric push rod receives the control signal and outputs a precise linear push / pull force, thereby driving the adjustment plate to move. The tension and pressure sensor measures the reaction force from the pulp on the adjustment plate in real time, which is a direct reflection of the pulp discharge resistance, and converts the force signal into an electrical signal to feed back to the control system. Under the drive of the electric push rod, the adjustment plate changes the size of the pulp outlet, thereby adjusting the juicing pressure. The observation window allows users to observe the pulp discharge and the dryness of the pulp. This solves the technical problem in the prior art, where pressure adjustment mostly relies on manual valve opening control, which cannot achieve closed-loop feedback and precise pressure regulation, and it is difficult to accurately control the pressure at the critical point that maximizes juice output without causing machine overload or blockage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A juicer with self-separating juice and pulp includes a frame 1, and a juicing mechanism is provided inside the frame 1. The juicing mechanism includes a screw rod 3, which conveys and squeezes fruits and vegetables through its structural features.

[0023] To ensure the stability of the output shaft rotation of motor 2, the juicing mechanism also includes motor 2. Motor 2 is fixedly mounted on the bottom support plate of frame 1. The output shaft of motor 2 is rotatably connected to the bottom support plate of frame 1 through a bearing seat. By fixing motor 2 to frame 1, the stability of the output shaft rotation of motor 2 is ensured. The model of motor 2 can be a DC brushless motor 2, which needs to be equipped with a power adapter and a BLDC motor 2 driver / controller to achieve precise speed control and facilitate setting different speeds for different ingredients.

[0024] To drive the screw rod 3 to rotate, the output shaft of the motor 2 drives the screw rod 3 to rotate via a synchronous belt. The screw rod 3 is rotatably connected to the inner wall of the groove of the frame 1 via bearings. The filter screen 31 is fixedly installed inside the frame 1 with bolts. The output shaft of the motor 2 is equipped with a main synchronous belt pulley. The end of the screw rod 3 located on the outside of the frame 1 is provided with a secondary synchronous belt pulley so that the high-speed rotational power of the motor 2 can be transmitted to the screw rod 3 through the synchronous belt transmission system at a certain transmission ratio to drive its rotation. The screw rod 3 is rotatably connected to the frame 1 via bearings to ensure the stability of the screw rod 3's rotation. The frame 1 is fixedly installed to the filter screen 31 with bolts, which not only fixes it but also facilitates disassembly for subsequent cleaning. Both the screw rod 3 and the filter screen 31 can be made of 304 stainless steel, which has extremely high strength and durability and is not easily deformed. The input shaft of the screw rod 3 passes through the hole in the frame 1 where a skeleton oil seal is located. It consists of a metal skeleton, a spring, and a fluororubber or nitrile rubber sealing lip. A dust cover or labyrinth seal can be added to the outside of the skeleton oil seal to form double protection and further prevent contaminants from entering.

[0025] In order to create a gradual and increasing extrusion pressure on the material, the screw rod 3 is located inside the filter screen 31. The outer ring of the screw blades of the screw rod 3 has triangular serrations 4. The screw rod 3 is located inside the filter screen 31, forming an annular extrusion chamber. The filter screen 31 provides a solid boundary and reaction force surface for extrusion, while the screw rod 3 is the power source for generating extrusion pressure in this closed space. The close cooperation between the two forms the structural basis for achieving efficient solid-liquid separation. The screw 3 is a variable-diameter screw 3; as the shaft diameter of the screw 3 increases, the volume of the extrusion chamber gradually decreases from front to back, thus creating a gradual, increasing extrusion force on the fruits and vegetables. This achieves a gentle yet efficient juicing process, which helps to increase the juice yield and retain the nutrients in the juice. The upper right side of the frame 1 is the feeding frame, where the operator pours the fruits and vegetables to be juiced into the frame 1. The triangular serrations 4 are located on the screw 3, directly opposite the feed inlet of the feeding frame, on the outer ring of the initial two or three spiral blades. This area is the first stop for the fruits and vegetables entering the juicer. When the triangular serrations 4 rotate, they act like a high... The rapidly rotating blade assembly forcibly grips, cuts, and tears the input fruits and vegetables, effectively preventing slippage and blockage of smooth or large pieces of fruit and vegetables, such as apples and carrots, at the feed inlet. This ensures a continuous and smooth feeding process. Before the fruits and vegetables enter the main extrusion zone, their cell structure has been initially damaged, greatly reducing the difficulty of subsequent extrusion. The fruit and vegetable juice flows through the discharge pipe with an electric valve under the frame 1. The rest of the screw 3 adopts a variable diameter design. The pre-crushed fruit and vegetable materials are transported to this area. As the shaft diameter of the screw 3 gradually increases from front to back, the volume of the extrusion chamber continuously decreases, thereby forming a gradual and increasing extrusion force on the material.

[0026] By setting up a juicing mechanism, fruits and vegetables are conveyed and squeezed. The high-speed rotation power of motor 2 is transmitted to screw rod 3 through a synchronous belt transmission system at a certain transmission ratio, driving it to rotate. Screw rod 3 is located inside filter screen 31, forming an annular squeezing chamber. Filter screen 31 provides a solid boundary and reaction force surface for squeezing, while screw rod 3 is the power source for generating squeezing force in this closed space. The close cooperation between the two is the structural basis for achieving efficient solid-liquid separation. Triangular saw teeth 4 are set on the screw rod 3, directly opposite the feed inlet of the feed frame, on the outer ring of the initial two or three spiral blades. This area is the first stop for fruits and vegetables entering the juicer. When rotating, triangular saw teeth 4 act like a high-speed rotating blade assembly, forcibly gripping, cutting, and tearing the input fruits and vegetables, effectively preventing smooth or large pieces of fruits and vegetables from being cut. This solves the technical problem in the prior art that when spiral blades come into contact with fruits and vegetables, they mainly rely on friction to push them, which is very limited for some smooth, hard, or irregularly shaped fruits and vegetables.

[0027] In order to adjust the slag discharge resistance at the end of the juicing chamber of the frame 1, an adjustment mechanism is provided inside the frame 1. The adjustment mechanism includes an adjustment plate 61. The movement of the adjustment plate 61 adjusts the slag discharge resistance at the end of the juicing chamber of the frame 1.

[0028] To control the forward and reverse rotation of the push rod motor, the adjustment mechanism also includes an electric push rod 5. The electric push rod 5 is fixedly installed on the left side surface of the slag discharge frame of the frame 1. The electric push rod 5 is fixedly installed to the slag discharge frame of the frame 1. The electric push rod 5 can be a DC electric push rod 5, which needs to be equipped with a relay or H-bridge drive circuit to control the forward and reverse rotation of the push rod motor, i.e., extension and retraction, which is controlled by the main control MCU. The extension rod of the electric push rod 5 passes through the hole of the slag discharge frame of the frame 1 and is sealed with a corrugated dust cover made of rubber or TPU material. One end of the cover is fixed to the hole of the frame 1, and the other end is fixed to the extension rod of the electric push rod 5. When the push rod extends and retracts, the corrugated tube will stretch and compress accordingly, forming a dynamic and flexible sealing barrier.

[0029] To measure the reaction force from the fruit pomace acting on the regulating plate 61 in real time, a tension / compression sensor 6 is fixedly installed at one end of the telescopic rod of the electric push rod 5. One end of the tension / compression sensor 6 is fastened to the outer side of the regulating plate 61. An observation window 62 is provided on the front surface of the slag discharge frame of the frame 1. One end of the telescopic rod of the electric push rod 5 can be fixedly installed to the tension / compression sensor 6 via a connecting flange. The electric push rod 5 receives control signals and outputs precise linear thrust / tension, thereby driving the regulating plate 61 to move. The tension / compression sensor 6 is connected to the regulating plate 61 via high-strength bolts. 1. Securely install the sensor 6. The tension / compression sensor 6 measures in real time the reaction force from the fruit pulp on the regulating plate 61, which is a direct reflection of the pulp discharge resistance. It converts the force signal into an electrical signal and feeds it back to the control system. Driven by the electric push rod 5, the regulating plate 61 changes the size of the pulp outlet, thereby adjusting the juicing pressure. The tension / compression sensor 6 can be an S-type sensor. S-type sensors can measure both tension and pressure, have a wide measurement range, and high accuracy, making them ideal for installation between the push rod and the regulating plate 61. A signal conditioning module / transmitter and a regulated power supply are required. To ensure measurement accuracy, a precise excitation voltage, typically 10V or 12V DC, is provided to the sensor. An observation window 62 is installed at the front end of the slag discharge frame of the frame 1, allowing users to easily observe the slag discharge and the dryness and moisture content of the fruit pomace. The window can be made of tempered glass or high-transparency polycarbonate, which meets food contact grade requirements and is resistant to high temperatures and impacts. A full-circle sealing gasket is added between the observation window 62 and the slag discharge frame. The gasket is made of food-grade silicone rubber or foamed silicone rubber. The observation window 62 and the sealing gasket are pressed tightly together onto the slag discharge frame using a pressure frame or flange, and then evenly tightened with bolts.

[0030] By setting an adjustment mechanism, the pulp discharge resistance at the end of the juicing chamber of the frame 1 is adjusted. The electric push rod 5 receives the control signal and outputs a precise linear push / pull force, thereby driving the adjustment plate 61 to move. The tension and pressure sensor 6 measures the reaction force from the pulp on the adjustment plate 61 in real time, which is a direct manifestation of the pulp discharge resistance, and converts the force signal into an electrical signal to feed back to the control system. Under the drive of the electric push rod 5, the adjustment plate 61 changes the size of the pulp outlet, thereby adjusting the juicing pressure. The observation window 62 allows users to observe the pulp discharge and the dryness of the pulp. This solves the technical problem in the prior art, where pressure regulation mostly relies on manual valve opening control, which cannot achieve closed-loop feedback and precise pressure regulation, and it is difficult to accurately control the pressure at the critical point that maximizes juice output without causing machine overload or blockage.

[0031] Working principle: The user puts the fruits and vegetables into the feeding box and presses the start button. The MCU sends an instruction to the BLDC motor 2 driver according to the selected program, driving the motor 2 to rotate at a preset speed. The power is transmitted to the screw rod 3 through the synchronous belt transmission system. The triangular saw teeth 4 at the feed port of the screw rod 3 start to rotate, forcibly grabbing, cutting and tearing the fruits and vegetables to prevent slippage and sending them into the juicing chamber. The pre-crushed fruits and vegetables are conveyed backward by the screw 3. Since the screw 3 is a variable diameter design, the volume of the extrusion chamber gradually decreases, forming a gradual and increasing extrusion force on the fruits and vegetables. Under the pressure, the juice seeps out from the mesh of the filter screen 31 and collects at the bottom of the frame 1 under the action of gravity. Finally, it flows out from the discharge pipe with an electric flange below. Users can place cups or storage tanks under the discharge pipe to collect the juice. The fruit pomace is continuously pushed against the regulating plate 61, generating a reaction force. The tension and pressure sensor 6 measures this force in real time, i.e., the slag discharge resistance, and converts it into an electrical signal. After being amplified by the signal conditioning module / transmitter, it is sent to the main control MCU. The MCU compares the real-time force value with the target pressure range set in the current program. For example, the program sets the target force to 150N and allows a fluctuation range of ±20N. If the real-time force value is less than 130N, i.e. the pressure is too low, the MCU judges that the slag discharge is too smooth and the pressure is insufficient, which may result in a low juice yield. It immediately sends a command to the H-bridge drive circuit to extend the telescopic rod of the electric push rod 5 forward, push the adjustment plate 61 to reduce the slag outlet and increase the resistance. If the real-time force value is >170N, that is, the pressure is too high, the MCU judges that the slag discharge is blocked and the pressure is too high, which may cause the motor 2 to be overloaded or blocked. It immediately commands the telescopic rod of the electric push rod 5 to retract backward, pull the adjustment plate 61 to increase the slag discharge port, and relieve pressure protection. If the real-time force value is between 130-170N, the pressure is normal, and the MCU will keep the electric push rod 5 in its current position. The process of collecting, comparing, deciding, and executing is carried out at an extremely high frequency, such as dozens of times per second, so that the juicing pressure is always dynamically stable within the optimal range, achieving intelligent control. Users can observe the dryness and wetness of the pulp in real time through the observation window 62 and intuitively feel the juicing effect; As the user stops feeding fruits and vegetables, the material in the juicing chamber is gradually processed. The force value detected by the tension and compression sensor 6 will decrease significantly and tend to stabilize. After the control system detects that the force value has been continuously lower than a certain threshold for more than a preset time, it determines that the juicing process is over. The MCU first controls the motor 2 to stop rotating. Then, the MCU controls the electric push rod 5 to completely retract the adjustment plate 61, so that the pulp outlet is opened to the maximum. The user can easily discharge the dry fruit pulp accumulated under the pulp outlet frame. Finally, the user turns off the power, and the equipment returns to standby or power-off state. The bearing housing supporting the output shaft of motor 2 and the bearing supporting the screw rod 3, as well as the contact surface between the adjusting plate 61 and the slide groove, must be lubricated with food-grade grease, such as grease conforming to NSF H1 standards. Whether the timing belt needs lubrication depends on the material; some timing belts do not require lubrication. It is recommended to add a small amount of food-grade grease to the oil filler of the bearing every 3-6 months or when you feel that the equipment noise is increasing or the operation is not smooth. After disassembly, you can apply a thin layer of food-grade grease to the inner wall of the slide groove to reduce friction, make the electric push rod 5 run more smoothly, and extend the life of the seal ring. After each use, unscrew the bolts securing the filter screen 31 and remove the filter screen 31, spiral rod 3, and feed frame. Thoroughly clean with water and a soft brush, wiping the inner and outer surfaces of the observation window 62 to ensure it is clear and that there is no fruit residue remaining in the slag discharge frame and the area of ​​the adjusting plate 61. Check the tension of the timing belt monthly. If it is too loose, it will slip, and if it is too tight, it will increase the load on the bearing and motor 2. This can be adjusted by adjusting the position of the motor 2 base. Check the bellows dust cover for damage. If it is damaged, replace it immediately to prevent liquid from contaminating the electric push rod 5. Check the skeleton oil seal for leakage. If liquid is found to be seeping from the motor 2 shaft or the screw rod 3 shaft, it means that the oil seal may have aged and failed and needs to be replaced. If the device displays abnormal pressure or cannot be adjusted, first check if the wiring of the tension / compression sensor 6 is secure. Then use a multimeter and a regulated power supply to check if its output signal is normal. Damaged sensors need to be replaced entirely. If the telescopic rod of the electric push rod 5 does not move or makes abnormal noise, check its power supply and control signal. If it is confirmed that the internal motor 2 or gears of the push rod are damaged, the entire electric push rod 5 assembly usually needs to be replaced. If the motor 2 does not turn or has insufficient torque, check the driver and power adapter. If it is confirmed that the problem is with the motor 2 itself, it needs to be replaced by a professional. The electronic devices, their power supply methods, and control methods described in this article are all existing technologies with mature applications. Therefore, they will only be briefly explained here without further elaboration.
