Description

Technical Field

[0001] This invention relates to the field of candied fruit juice extraction machine technology, specifically a rolling circulating pressure candied fruit juice extraction machine. Background Technology

[0002] In the industrial mass production and processing of candied fruit, fresh fruit is fed into a juice extractor, which quickly dehydrates and dries the fruit, reducing the water content. Inside the juice extractor, a mechanical extrusion structure quickly squeezes out and separates the juice from the inside of the candied fruit. The fruit is then processed through other processes to become candied food.

[0003] A citrus juice extraction mechanism with application number CN207590468U includes a conveyor belt and a juice extraction device connected to the conveyor belt end. The juice extraction device includes a housing and a cutting mechanism, a pressing mechanism, and a slag discharge mechanism sequentially installed within the housing. The cutting mechanism includes an arc-shaped pressure plate installed above the conveyor belt end and a cross-shaped cutter located on one side of the arc-shaped pressure plate. Due to the adoption of the above technical solution, the citrus juice extraction mechanism of this utility model cuts the citrus fruit into small pieces using the cross-shaped cutter before pressing, and then presses it after crushing. This improves pressing efficiency while reducing the force required for pressing, reducing energy consumption. Simultaneously, the pressing is more thorough, avoiding excessive moisture in the filter residue. However, this juice extraction device does not easily disperse the pressed fruit during use; the fruit accumulating together hinders the rapid separation of internal moisture, affecting the production and application effect of the juice extraction machine.

[0004] A drum juicer with application number CN201595644U includes a middle base, an upper cover above the middle base, a pressure bar cooperating with the upper cover, a main unit below the middle base, a grinding blade inside the middle base, and a drum filter screen on the outer edge of the grinding blade. The grinding blade includes a juicing disc, a grinding ring on the outer circumference of the juicing disc, and an upper grinding ring on the upper cover that cooperates with the grinding ring. Compared to existing technologies, this juicer significantly improves the juice yield and reduces resource waste. However, the force applied to the fruit is difficult to control during use, resulting in a limited juice extraction effect.

[0005] When using some existing juice extractors, the fruits are compressed and piled together under pressure. Fruits in the middle are subjected to less pressure, which affects the extraction of juice from the internal fruits. Furthermore, the pressure applied to the fruits by some existing juice extractors is not easy to control. Applying a uniform force to the fruits piled in the equipment results in a decrease in the extraction rate in the later stages of processing.

[0006] Therefore, a rolling, circulating pressure candied fruit juice extractor needs to be designed to address the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a rolling, circulating pressure fruit juice extractor to solve the problems mentioned in the background art, such as the fruit being pressed and piled together under pressure during use, with the fruit in the middle receiving less pressure, affecting the extraction of juice from the internal fruit, and the pressure applied to the fruit by existing partial juice extractors being difficult to control, resulting in a decrease in the extraction rate in the later stages of processing due to the uniform force applied to the fruit piled in the equipment.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rolling circulating pressure candied fruit juice extractor, wherein the juice extractor is mounted on a workbench, and an extrusion cylinder is fixedly mounted on the upper surface of the workbench via a mounting base, and an inlet is connected through the left side of the extrusion cylinder, and an outlet is connected through the right side of the extrusion cylinder.

[0009] A rolling, circulating pressure fruit juice extractor includes:

[0010] The inner left and right sides of the extrusion cylinder are fitted and fixed with inner rings, and a roller is installed between the inner rings on the left and right sides. A mesh is fitted and installed inside the side of the roller, and a toothed ring is fixedly provided at the middle position of the outer side of the roller.

[0011] A flow guide is installed through the lower part of the extrusion cylinder and is connected to the upper surface of the workbench. A material guide plate is fixedly installed on the right side of the workbench. A support frame is fixedly installed on the lower inner side of the workbench. A servo motor is fixedly installed on the upper surface of the support frame. A drive screw is connected to the side output end of the servo motor. A drive frame is sleeved on the outside of the drive screw. The drive frame is connected through the side plate and the side plate is fitted and fixed on the inner side of the workbench. An extrusion disc is fixedly installed on the upper outer side of the drive frame. A wireless pressure sensor is fitted inside the side of the extrusion disc.

[0012] The rolling pressure mechanism is located on the lower outer side of the drum, and the rolling pressure mechanism causes the candied fruit inside the drum to repeatedly undergo dejuicing.

[0013] The vibrating material dispersing mechanism is located inside the extrusion cylinder and the guide shroud, and the operation of the vibrating material dispersing mechanism acts on the drum to disperse the candied fruit processed inside.

[0014] The progressive extrusion mechanism is located on the side of the drive frame, and the progressive extrusion mechanism allows the processing pressure of the juice extractor to gradually increase.

[0015] Preferably, the lower part of the drive frame and the drive screw form a threaded transmission structure, and the drive frame, the side plate and the feed port pass through to form a transverse sliding structure. The drive frame moves left and right to push the extrusion disc into the inside of the drum. The servo motor controls the rotation of the drive screw, and under the action of the threaded transmission structure, the drive frame can be controlled to move left and right reciprocatingly to realize the cyclic pressure dehydration of the candied fruit.

[0016] Preferably, the rolling pressure application mechanism consists of a transmission rod, a drive gear, a transmission disc, and a belt;

[0017] The transmission rod is rotatably mounted inside the guide shield, and a drive gear is fixedly mounted at the middle position of the outer side of the transmission rod. The transmission disc is fixedly mounted on the outer side of the transmission rod and the outer side of the drive screw, and the upper and lower sets of transmission discs are connected to each other by a belt.

[0018] This component can control the rotation of the roller inside the extrusion cylinder, so that the candied fruit can drain juice from multiple directions, allowing the fruit moisture on the sides of the roller to be discharged outwards.

[0019] Preferably, the drive gear forms a meshing transmission structure with the roller through a gear ring, and the roller forms a rotating structure with the extrusion cylinder through an inner ring; the rotation of the roller can be controlled through the meshing transmission structure.

[0020] Preferably, the vibrating material handling mechanism consists of a vibrating frame, a vibrating block, a positioning block, a slide bar, a transverse vibrating spring, a T-shaped frame, a sliding frame, a longitudinal vibrating spring, and a cam.

[0021] The vibrating frame is sleeved on the outside of the roller, and a vibrating block is fixedly installed on the upper inner side of the vibrating frame. The positioning block is fixedly installed on the lower inner side wall of the vibrating frame. Slide rods are fixedly connected to the outer two sides of the vibrating frame. A transverse vibration spring is sleeved on the outside of the slide rod. The side of the slide rod is connected through to the side of the T-shaped frame. The sliding frame is installed on the outside of the T-shaped frame. The upper and lower sides of the T-shaped frame are connected to longitudinal vibration springs. The sliding frame is fixedly installed on the inner side wall of the guide shroud. The cam is fixedly installed on the outside of the transmission rod.

[0022] This component can generate vibration force on the candied fruit inside the drum, making the candied fruit more dispersed in the drum, so that the moisture in the fruit can be discharged quickly and efficiently.

[0023] Preferably, the vibrating frame is positioned above the outer side of the drum via vibrating blocks, and below the vibrating frame is positioned below the outer side of the cam via positioning blocks. Four sets of vibrating frames are provided on the outside of the drum. The vibrating frame is controlled to vibrate in the up-down and left-right directions. The vibrating blocks act on the surface of the drum, causing the drum to vibrate to a certain extent, so that the fruits piled inside are more dispersed.

[0024] Preferably, the side of the vibration frame forms a transverse elastic sliding structure with the T-shaped frame through a sliding rod and a transverse vibration spring, and the T-shaped frame forms a longitudinal elastic sliding structure with the sliding frame through a longitudinal vibration spring; this part of the elastic sliding structure can control the vibration of the vibration frame in the up-down and left-right directions.

[0025] Preferably, the progressive extrusion mechanism consists of a guide rod, an inner guide rod, a lower sliding ring, a fixed block, an upper sliding ring, a cylinder, a pressure block, a protective cover, an infrared sensor, a signal receiving controller, a round rod, a stroke control block, a transmitter, an upper contact block, a lower contact block, and a limit spring.

[0026] The guide rod is fixedly connected to the side of the side plate, and an inner guide rod is also fixedly connected to the side of the side plate. A sliding ring is sleeved on the outside of the guide rod. The upper surface of the sliding ring is connected to the upper sliding ring through a fixing block. A cylinder is fixedly installed on the inner top surface of the upper sliding ring, and a pressure block is fixedly connected to the lower lifting end of the cylinder. The protective cover is fixedly installed on the lower surface of the sliding ring. Infrared sensors are fixedly installed on the inner walls of the front and rear sides of the protective cover. A signal receiving controller is fixedly installed on the outside of the protective cover. A round rod is fixedly connected to the middle of the inner side of the protective cover. A stroke control block is sleeved on the outside of the round rod. Transmitters are symmetrically fixed on the front and rear sides of the stroke control block. The upper contact block is fixedly installed on the lower surface of the stroke control block. A lower contact block is correspondingly provided below the upper contact block. The lower contact block is fixedly installed on the side of the lower rod of the drive frame. The limiting spring is connected to the side of the stroke control block.

[0027] This component can control the extrusion disc to apply progressive pressure to the fruit on the side, so that the juice in the fruit can be separated out quickly and effectively.

[0028] Preferably, the protective cover, the lower sliding ring, the fixing block, and the upper sliding ring are fixed as an integrated drive structure, and the upper sliding ring and the lower sliding ring respectively form a left-right sliding structure with the guide rod, and the fixing block forms a left-right sliding structure with the inner guide rod. The rods above the guide rod and the pressure block are distributed vertically and vertically. Under the contact thrust of the upper and lower contact blocks, the lateral sliding movement of the upper and lower sliding rings can be controlled.

[0029] Preferably, the stroke control block forms an elastic sliding structure with a limiting spring and a round rod, and the positions of the transmitters and infrared sensors on the front and rear sides of the stroke control block correspond to each other, and the infrared sensors are evenly distributed inside the protective cover; by detecting the correspondence between the transmitters and the infrared sensors at different positions, the progressive movement of the extrusion disc can be controlled to apply pressure.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: the rolling circulating pressure candied fruit juice extractor is equipped with a rolling circulating pressure mechanism, a vibrating material dispersing mechanism, and a progressive extrusion mechanism, which improves the juice extraction effect of candied fruit. The specific details are as follows:

[0031] 1. The inner and outer sides of the drum are equipped with a rolling circulation pressure mechanism. When the fruit is put into the drum, the servo motor controls the drive screw to rotate. Under the action of the threaded transmission structure, the drive frame is controlled to move laterally reciprocatingly. The drive frame pushes the extrusion disc to move laterally reciprocatingly inside the drum. The extrusion disc circulates and reciprocates on the side of the fruit to squeeze and dehydrate, thus controlling the fruit to dehydrate quickly.

[0032] Furthermore, during the reciprocating extrusion process, under the action of the meshing transmission structure of the drive gear and the gear ring, the roller can be controlled to rotate inside the extrusion cylinder, so that the juice inside the fruit at multiple locations on the side of the roller can be quickly discharged outward, improving the efficiency of fruit dejuicing.

[0033] 2. The drum is equipped with a vibrating material distribution mechanism. When the transmission rod rotates through the transmission structure, it drives the external cam to rotate synchronously. The cam controls the reciprocating vibration of the vibrating frame in the up-down and left-right directions by contacting the side extrusion positioning block. The vibrating frame acts on the drum surface through the inner vibrating block, controlling the drum to generate vibration in multiple directions. This makes the fruit distribution inside the drum more dispersed, which can not only avoid clogging the mesh, but also allow the fruit piled up in some places to exchange positions inside and outside under the action of vibration, so as to squeeze and dejuic the fruit more evenly.

[0034] 3. A progressive extrusion mechanism is installed under the workbench. When the extrusion disc is used to extrude juice from the fruit by pressing it to the side, the cylinder can be controlled to run under the sensing of the wireless pressure sensor. This causes the pressure block to press down onto the surface of the guide rod, thereby limiting the movement of the upper and lower sliding rings and thus limiting the position of the initial extrusion force of the extrusion disc.

[0035] Furthermore, during the lateral reciprocating movement of the drive frame, the upper contact block and stroke control block are moved laterally synchronously by the lower contact block. Under the sensing and detection of the transmitter and infrared sensor, the position of the drive frame's lateral movement can be controlled in a stepwise manner, thereby gradually increasing the position of the extrusion disc's cyclic extrusion and the stroke-progressive extrusion force, so as to more quickly and effectively control the outward discharge of fruit juice.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] like Figures 1-5 As shown, the juice extractor is equipped with a rolling pressure mechanism to repeatedly complete the juice extraction process for candied fruit. The specific structure is as follows:

[0052] A rolling circulating pressure candied fruit juice extractor is mounted on a workbench 1. An extrusion cylinder 3 is fixedly mounted on the upper surface of the workbench 1 via a mounting base 2. An inlet 4 is connected through the left side of the extrusion cylinder 3, and an outlet 5 is connected through the right side of the extrusion cylinder 3.

[0053] The inner left and right sides of the extrusion cylinder 3 are fitted and fixed with inner rings 6, and rollers 7 are installed between the inner rings 6 on the left and right sides. A grid 8 is fitted and installed inside the side of the roller 7, and a toothed ring 9 is fixedly installed at the middle position of the outer side of the roller 7.

[0054] A flow guide shroud 10 is installed through the bottom of the extrusion cylinder 3, and the flow guide shroud 10 is connected through the upper surface of the workbench 1. A material guide plate 11 is fixedly installed on the right side of the workbench 1. A support frame 12 is fixedly installed on the lower inner side of the workbench 1. A servo motor 13 is fixedly installed on the upper surface of the support frame 12. A drive screw 14 is connected to the side output end of the servo motor 13. A drive frame 15 is sleeved on the outside of the drive screw 14. The drive frame 15 is connected through the side plate 16, and the side plate 16 is fitted and fixed on the inner side of the workbench 1. An extrusion disc 17 is fixedly installed on the upper outer side of the drive frame 15. A wireless pressure sensor 18 is fitted inside the side of the extrusion disc 17.

[0055] The rolling pressure mechanism is located on the lower outer side of the drum 7, and the rolling pressure mechanism causes the candied fruit inside the drum 7 to repeatedly undergo dejuicing operations.

[0056] The drive frame 15 and the drive screw 14 form a threaded transmission structure below the drive frame 15, and the drive frame 15, the side plate 16 and the feed port 4 pass through to form a transverse sliding structure. The drive frame 15 moves left and right to push the extrusion disc 17 into the inside of the drum 7. The rolling pressure mechanism consists of a transmission rod 19, a drive gear 20, a transmission disc 22 and a belt 23. The transmission rod 19 is rotatably installed inside the guide shroud 10, and the drive gear 20 is fixedly installed at the middle position of the outer side of the transmission rod 19. The transmission disc 22 is fixedly installed on the outer side of the transmission rod 19 and the outer side of the drive screw 14, and the upper and lower sets of transmission discs 22 are connected to each other by the belt 23. The drive gear 20 forms a meshing transmission structure with the drum 7 through the toothed ring 9, and the drum 7 forms a rotating structure with the extrusion cylinder 3 through the inner ring 6.

[0057] The fruit is controlled to enter the interior of the drum 7 through the feed port 4. The servo motor 13 controls the drive screw 14 to rotate. Under the action of the threaded transmission structure, the drive frame 15 is controlled to move laterally and reciprocally through the interior of the side plate 16. The drive frame 15 pushes the extrusion disc 17 to move left and right and reciprocally. When the extrusion disc 17 moves to the right and enters the interior of the drum 7, it extrudes the fruit inside the drum 7 to remove juice (closes the discharge port 5). Under the action of pressure, the juice inside the fruit is discharged outward. The juice flows through the mesh 8 to the interior of the guide hood 10 and is finally discharged outward through the discharge pipe below the guide hood 10.

[0058] During the extrusion and dejuicing process, the drive screw 14 rotates, causing the external transmission disc 22 to rotate synchronously. The upper and lower transmission discs 22 are driven by the belt 23, which can control the transmission rod 19 to rotate on the inner side of the guide shroud 10. The transmission rod 19 drives the externally fixed drive gear 20 to rotate synchronously. The outer side of the drive gear 20 meshes with the outer side of the gear ring 9. Under the action of the meshing transmission structure, the gear ring 9 and the roller 7 can be controlled to rotate on the inner side of the extrusion cylinder 3. During the rotation of the roller 7, rolling extrusion and dejuicing can be achieved, so that the fruit juice on the inner side of the roller 7 can be quickly discharged to the outside.

[0059] Example 2

[0060] like Figures 6-8 As shown, the juice extractor is equipped with a vibrating material dispersing mechanism, which causes the candied fruit to move and disperse inside the drum 7, ensuring that the candied fruit is extracted evenly from both the inside and outside of the drum. The specific structure is as follows:

[0061] The vibrating material dispersing mechanism is located inside the extrusion cylinder 3 and the guide shroud 10, and the vibrating material dispersing mechanism operates on the drum 7 to disperse the candied fruit processed inside.

[0062] The vibrating material handling mechanism consists of a vibrating frame 24, vibrating blocks 25, positioning blocks 26, slide rods 27, transverse vibrating springs 28, a T-shaped frame 29, a sliding frame 30, a longitudinal vibrating spring 31, and a cam 21. The vibrating frame 24 is fitted around the outside of the drum 7, and the vibrating blocks 25 are fixedly installed on the upper inner side of the vibrating frame 24. The positioning blocks 26 are fixedly installed on the lower inner side wall of the vibrating frame 24, and slide rods 27 are fixedly connected to both sides of the outer side of the vibrating frame 24. Transverse vibrating springs 28 are fitted around the outside of the slide rods 27, and the sides of the slide rods 27 are connected through to the sides of the T-shaped frame 29. The sliding frame 30 is installed outside the T-shaped frame 29, and the T-shaped frame 29 is connected through to the sides of the T-shaped frame 29. The upper and lower sides of the T-shaped frame 29 are connected with longitudinal vibration springs 31, and the sliding frame 30 is fixedly installed on the inner wall of the guide shroud 10. The cam 21 is fixedly installed on the outside of the transmission rod 19. The upper part of the vibration frame 24 is correspondingly set on the outer side of the roller 7 through vibration blocks 25, and the lower part of the vibration frame 24 is correspondingly set on the outer side of the cam 21 through positioning blocks 26. Four sets of vibration frames 24 are provided on the outside of the roller 7. The sides of the vibration frame 24 form a transverse elastic sliding structure with the T-shaped frame 29 through the slide rod 27 and the transverse vibration spring 28, and the T-shaped frame 29 forms a longitudinal elastic sliding structure with the sliding frame 30 through the longitudinal vibration spring 31.

[0063] During the extrusion and dejuicing process, the transmission rod 19 rotates, driving the externally fixed cam 21 to rotate synchronously. The cam 21 contacts the extrusion positioning block 26 through the side arc surface. When the positioning block 26 is subjected to the extrusion force, the control slide rod 27, under the action of the transverse vibration spring 28, passes through the side of the T-shaped frame 29 and vibrates back and forth elastically. The control T-shaped frame 29 is also subjected to the up and down elastic vibration of the inner side of the sliding frame 30 through the longitudinal vibration spring 31. This part of the vibration force is transmitted to the roller 7 through the vibration frame 24 and the vibration block 25, so that the roller 7 and the grid 8 generate a certain vibration force, thereby dispersing the fruits that are extruded and piled up inside, so that the fruits are relatively dispersed in the roller 7 (when the extrusion disc 17 moves to the left to extrude the piled fruits, the fruits are dispersed under the action of vibration force. The fruits on the inside and outside of the local position alternate between the inside and outside positions under the action of the rotation and vibration of the roller 7, so that the fruits on the inside and outside can be subjected to strong extrusion force, improving the uniformity of extrusion and dejuicing of the fruits), so that the extrusion disc 17 can repeatedly apply pressure and dejuicing.

[0064] Example 3

[0065] like Figures 9-12 As shown, the juice extractor is equipped with a progressive extrusion mechanism. The extraction pressure gradually increases with the number of extrusions, and the extraction process proceeds sequentially. The specific structure is as follows:

[0066] The progressive extrusion mechanism is located on the side of the drive frame 15, and the progressive extrusion mechanism can make the processing pressure of the juice extractor gradually increase progressively.

[0067] The progressive extrusion mechanism consists of a guide rod 32, an inner guide rod 33, a lower sliding ring 34, a fixing block 35, an upper sliding ring 36, a cylinder 37, a pressure block 38, a protective cover 39, an infrared sensor 40, a signal receiving controller 41, a round rod 42, a stroke control block 43, a transmitter 44, an upper contact block 45, a lower contact block 46, and a limit spring 47. The guide rod 32 is fixedly connected to the side of the side plate 16, and the inner guide rod 33 is also fixedly connected to the side of the side plate 16. The guide rod 32 is externally sleeved and installed. A sliding ring 34 is provided, the upper surface of which is connected to an upper sliding ring 36 via a fixing block 35. A cylinder 37 is fixedly installed on the inner top surface of the upper sliding ring 36, and a pressure block 38 is fixedly connected to the lower lifting end of the cylinder 37. A protective cover 39 is fixedly installed on the lower surface of the sliding ring 34, and infrared sensors 40 are fixedly installed on the front and rear inner walls of the protective cover 39. A signal receiving controller 41 is fixedly installed on the outside of the protective cover 39, and a circular... A rod 42 is provided, and a travel control block 43 is sleeved on the outside of the rod 42. A transmitter 44 is symmetrically fixed on both the front and rear sides of the travel control block 43. An upper contact block 45 is fixedly installed on the lower surface of the travel control block 43, and a lower contact block 46 is correspondingly provided below the upper contact block 45. The lower contact block 46 is fixedly installed on the side of the lower rod of the drive frame 15. A limit spring 47 is connected to the side of the travel control block 43. The protective cover 39, the sliding ring 34, the fixing block 35, and the upper sliding ring 36 are fixed together. The integrated drive structure has an upper sliding ring 36 and a lower sliding ring 34 forming a left-right sliding structure with the guide rod 32, and a fixed block 35 forming a left-right sliding structure with the inner guide rod 33. The rods above the guide rod 32 and the pressure block 38 are distributed vertically and vertically. The stroke control block 43 forms an elastic sliding structure with the round rod 42 through the limiting spring 47. The positions of the transmitters 44 on the front and rear sides of the stroke control block 43 and the infrared sensors 40 correspond to each other. The infrared sensors 40 are evenly distributed and arranged inside the protective cover 39.

[0068] When the servo motor 13 initially drives the extrusion and dejuicing process, the drive frame 15 moves to the right, causing the fixed lower contact block 46 to move laterally. The lower contact block 46 and the upper contact block 45 are distributed correspondingly on the left and right sides. When the lower contact block 46 moves to the side position of the upper contact block 45, it pushes the upper contact block 45 and the stroke control block 43 to move laterally first. When the stroke control block 43 moves to the right limit position outside the round rod 42 (affected by the side limit spring 47), the stroke control block 43 continues to move to the right, causing the protective cover 39 to move to the right synchronously. At this time, the upper sliding ring 36 and the lower sliding ring 34 are both sleeved on the outside of the guide rod 32 and slide laterally. When the extrusion disc 17 moves to the right and extrudes to a certain extent (sensed by the wireless pressure sensor 18) The pressure changes are detected by setting a pressure detection range to prevent the extrusion disc 17 from excessively extruding to the right, which would cause severe damage to the fruit. When the wireless pressure sensor 18 detects and senses the pressure range, it transmits the signal to the external controller. The controller controls the servo motor 13 to drive in the opposite direction, thereby controlling the drive frame 15 to move to the left and move the extrusion disc 17 (towards the extruded fruit). At this time, the cylinder 37 runs and pushes the pressure block 38 to move downward, so that the pressure block 38 is pressed and placed on the upper surface of the guide rod 32. The pressure action limits the sliding position of the upper slip ring 36 and the lower slip ring 34. Under the action of the induction drive structure, the extrusion disc 17 and the drive frame 15 move to the left, and the lower contact block 46 and the upper contact block 45 separate from each other.

[0069] Then, when the drive frame 15 moves to the right again to apply pressure and remove juice, the lower contact block 46 and the upper contact block 45 come into contact. Under the pushing action of the lower contact block 46, the stroke control block 43, which is sleeved on the outside of the round rod 42, slides to the right. The stroke control block 43 drives the transmitters 44 on both sides to move synchronously. The signal emitted by the transmitter 44 corresponds to the infrared sensor 40 at the corresponding position inside the protective cover 39. The infrared sensor 40 transmits the detection signal to the signal receiving controller 41. The signal receiving controller 41 transmits the signal to the main controller, which drives the servo motor 13 in reverse, thereby causing the drive frame 15 to drive the extrusion disc 17 to move in the opposite direction again. If the drive frame 15 and the extrusion disc 17 are controlled to move left and right in a cyclical manner multiple times, each movement causes the transmitter 44 to correspond to the horizontally arranged infrared sensors 40 in sequence, so that the distance of each movement of the drive frame 15 gradually increases, thereby allowing the extrusion disc 17 to form a progressive extrusion force, so as to more quickly and effectively control the extrusion of juice from the inside of the fruit.
