Within the movable groove 17, the two slide in cooperation; rotating connecting rods 18 are installed on both sides of the rotating horizontal block 16; the two rotating connecting rods 18 are connected to both sides of the displacement T-plate 5; the displacement spring 19 is sleeved on the displacement cylinder 4; one end of the displacement spring 19 is fixedly connected to the U-shaped base frame 3, and the other end is connected to the displacement limiting plate; the displacement limiting plate is connected to the end of the displacement cylinder 4 away from the displacement T-plate 5; the pressure spring 20 is sleeved on the pressure square column 7; one end of the pressure spring 20 is fixedly connected to the pressure horizontal plate 6, and the other end is fixedly connected to the cutter 8; conductive patch 21; two conductive patches 21 are respectively installed on the opposite sides of the displacement T-plate 5 and the U-shaped base frame 3; the two conductive patches 21 are electrically connected; the displacement rack 22 is installed on the displacement T-plate 5; The rack 22 and the reversing gear 10 are meshed and connected; the reciprocating U-shaped seat 30 is installed on both sides of the pressure plate 6; the reciprocating screw 31 is connected inside the reciprocating U-shaped seat 30; a reciprocating cylinder 32 is installed inside the reciprocating U-shaped seat 30; a reciprocating block 33 is connected through to the reciprocating cylinder 32, and the two are slidably engaged; the reciprocating block 33 is threadedly connected to the reciprocating screw 31; a rotary motor 34 is installed on the side of the reciprocating U-shaped seat 30; the output end of the rotary motor 34 is rotatably connected to the reciprocating screw 31; a reciprocating scraper 35 is installed on the reciprocating block 33; the initial position of the reciprocating scraper 35 is spaced from the end point of the cutter 8, and when the reciprocating scraper 35 moves, it will contact the side wall of the cutter 8; the moving path of the reciprocating scraper 35 covers the area between the two ends of the cutter 8;

[0056] Fruit is placed on conveyor belt 2 for transport. When the fruit is conveyed to below the cutter 8, the drive motor 11 is started, and its output end drives the rotating disc 12 to rotate. This causes the rotating column 13 on the disc to move back and forth within the rotating groove 17, which in turn causes the rotating horizontal block 16 on the disc to move back and forth at the rotating base 14 via the rotating cylinder 15. Under the action of the rotating connecting rod 18, the rotating horizontal block 16 drives the displacement T-plate 5 to move back and forth, continuously moving it closer to and away from the top of the conveyor belt 2. This causes the displacement T-plate 5 to move back and forth at the U-shaped base 3 via the displacement cylinder 4, keeping the displacement spring 19 in a buffering and resetting state. The elastic potential energy generated by the displacement spring 19 can assist the displacement T-plate 5 in resetting and moving. At the same time, the buffering force brought by the displacement spring 19 can absorb and reduce the impact force generated when the cutter 8 contacts the fruit, improving the stability during cutting. In addition, the displacement spring 19 can also be used for... The support plate 8 counteracts some of the gravity and limits the falling speed of the cutter 8, preventing excessive impact when it comes into contact with the fruit, which could damage the transmission belt 2. This reduces the limitations of the device during use and improves the cutting effect. The displacement plate 5 synchronously drives the pressure plate 6 to move back and forth, which, under the action of the pressure column 7 and the pressure spring 20, drives the cutter 8 to move back and forth. The distance of each reciprocating movement is consistent, allowing the cutter 8 to evenly contact the fruit, thus evenly cutting the fruit conveyed below the cutter 8 into pieces. This avoids uneven cutting that could result in broken pieces or uneven sizes, improving the quality of the fruit pieces and enhancing the cutting effect of the device. After the fruit is evenly cut into pieces, it is rapidly frozen at low temperature and then dried to make dried fruit, retaining the main nutrients and flavors such as sugar, vitamins, and minerals in the fruit, thus improving the production effect of dried fruit.

[0057] When the cutter 8 moves downwards to cut fruit, it will come into contact with the fruit. If it encounters hard fruit that is difficult to cut, the displacement T-plate 5 can continue to move the cutter 8 downwards. This causes the pressure plate 6 on the displacement T-plate 5 to move at the pressure column 7, keeping the pressure spring 20 in a buffer state. This allows it to continuously apply pressure to the fruit in contact with the cutter 8 until the fruit is cut into pieces, avoiding damage from hard contact and making the cutting effect more stable. The deformation of the pressure spring 20 buffers the pressure, preventing the cutter 8 and the transmission belt 2 from breaking due to sudden hard force. Wear and tear are reduced, and the pressure spring 20 adjusts its force slightly according to the hardness of the fruit. The force gradually increases to cut the fruit, while the force does not deform the fruit due to excessive pressure. This adapts to fruits of different hardness, improving the cutting effect of the device. At the same time, the gentle pressure allows the cutter 8 to keep in contact with the fruit. Even if the fruit deviates slightly, the pressure spring 20 can buffer the cutter 8 to keep up with the pressure, avoiding the situation of "not being able to cut". This reduces the limitations of the device and improves the stability and effect of cutting.

[0058] Simultaneously, when the cutter 8 completes its downward cutting operation during each reciprocating movement and returns to its original position, the displacement T-plate 5 on it gradually approaches the U-shaped base 3, causing the conductive pads 21 on their opposite sides to contact each other. This indicates that the cutter 8 has returned to its initial position and is ready to begin the next round of reciprocating movement for cutting. During this process, the contact between the two conductive pads 21 sends a signal to the control center to start the rotary motor 34, which drives the reciprocating screw 31 to rotate. This causes the threaded reciprocating block 33 to reciprocate at the reciprocating cylinder 32, thereby driving the reciprocating scraper 35 to reciprocate. This scraper moves back and forth on both sides of the cutter 8 to clean the fruit pieces adhering to the cutter 8. This process occurs during the downward movement of the cutter 8, and before contacting the fruit, the reciprocating scraper 35 returns to its initial position to await the next cleaning operation. To prevent cut fruit pieces from adhering to the cutter 8, which would cause uneven cutting and result in broken pieces, thus improving the appearance and size consistency of the finished fruit pieces; at the same time, during each cutting stroke of the cutter 8 (before the cutter 8 touches the fruit), the reciprocating scraper 35 will work to sweep the cut fruit pieces adhering to the cutter 8 onto the conveyor belt 2, preventing the cut fruit pieces from gradually accumulating on the cutter 8, hindering its normal operation and causing frequent production line shutdowns for cleaning, thereby improving the cutting efficiency of the device and reducing the limitations of the device in use; at the same time, the initial position of the reciprocating scraper 35 is spaced from the end point of the cutter 8, so it will not interfere with the cutting operation of the cutter 8, and the start-up time of the rotary motor 34 when the two conductive pads 21 contact is limited to one round trip of the threaded reciprocating block 33.

[0059] In this embodiment, the frame 1 is equipped with a stop adjustment unit for adjusting the distance between the cutter 8 and the transmission belt 2. The stop adjustment unit includes a positioning groove 9, which is located on the top of the frame 1; a positioning plate 23, which is fitted into the positioning groove 9 and the two slide in cooperation; a positioning cylinder 24, which is installed on the side of the U-shaped base frame 3 near the top of the frame 1; the positioning cylinder 24 is fitted into the positioning groove 9 and the two slide in cooperation; the positioning plate 23 is located on the moving path of the positioning cylinder 24; a positioning spring 25 is located in the positioning groove 9; one end of the positioning spring 25 is fixedly connected to the positioning groove 9, and the other end is fixedly connected to the positioning plate 23; and a limiting cylinder 26 is fixedly installed on the... The frame 1 has a side wall; a limiting slider 27; the limiting slider 27 is connected to the limiting cylinder 26 on the side near the frame 1; the limiting cylinder 26 and the limiting slider 27 are in sliding fit; a limiting insert 28 is fixedly installed on the side of the limiting slider 27 near the frame 1; a limiting spring 29 is sleeved on the limiting cylinder 26; one end of the limiting spring 29 is fixedly connected to the limiting slider 27, and the other end is fixedly connected to a limiting circular plate, which is fixedly connected to the end of the limiting cylinder 26 away from the frame 1; the outer wall of the positioning cylinder 24 has several equidistantly arranged limiting slots 36; the limiting insert 28 passes through the outer wall of the frame 1 and enters the positioning groove 9, connecting with one of the limiting slots 36;

[0060] When the device needs to cut fruit into pieces, the positioning cylinder 24 on the U-shaped base frame 3 is aligned with the positioning groove 9 on the top of the frame 1 and inserted. The U-shaped base frame 3 is then installed on the top of the frame 1, allowing the cutter 8 on the U-shaped base frame 3 to cut the fruit into pieces. The positioning cylinder 24 on the U-shaped base frame 3 is limited within the positioning groove 9 to position the movement of the U-shaped base frame 3 and prevent shaking that could cause deviations in the installation position. After entering the positioning groove 9, the positioning cylinder 24 contacts the positioning plate 23, both of which are limited within the positioning groove 9. This keeps the positioning spring 25 in a buffer state until the cutter 8 is moved and adjusted to the required cutting height. Then, the limiting slider 27, which was originally pulled outward, is released, allowing the limiting spring 29, which was in a buffer state, to reset and move the limiting slider 27 back to its original position on the limiting cylinder 26. The movement causes the limiting block 28 on the limiting slider 27 to pass through the outer wall of the frame 1 and enter the positioning groove 9, connecting with one of the limiting slots 36. This limits the positioning cylinder 24, preventing the cutter 8 on the U-shaped base frame 3 from dislodging due to non-human factors during use, thus reducing the limitations of the device's use. Simultaneously, it allows for the installation of the U-shaped base frame 3, fixing the cutter 8 at the current height for cutting fruit. Furthermore, when the positioning cylinder 24 is limited, the positioning spring 25, which is in a buffer state, cannot return to its original position. The resulting elastic force acts on the positioning cylinder 24, increasing the contact strength and friction between the limiting block 28 and the limiting slot 36. This prevents the limiting block 28 from shifting due to non-human factors during the positioning process, improving the safety and effectiveness of the device.

[0061] When the U-shaped base frame 3 needs to be disassembled for maintenance of the cutter 8, the limiting slider 27 is pulled outward, causing it to move at the upper limit of the limiting cylinder 26. This puts the limiting spring 29 in a buffer state, causing the limiting insert 28 on the limiting slider 27 to disengage from the frame 1 and no longer be located in the positioning groove 9. Simultaneously, it is no longer connected to the limiting slot 36, thus releasing the limiting setting on the positioning cylinder 24. This allows the positioning spring 25, which was in a buffer state, to reset, allowing the U-shaped base frame 3 to pop out. This completes the disassembly operation of the U-shaped base frame 3, preventing it from being installed on top of the frame 1. The installation and removal operation is convenient and quick, and does not require any tools. This allows for easy maintenance or replacement of the cutter 8 on the U-shaped base frame 3, reducing the limitations of the device during use. It is also worth mentioning that several limit slots 36 are provided and arranged at equal intervals, allowing the limit blocks 28 to limit the positioning cylinder 24 to different heights. This means the U-shaped base frame 3 is fixedly installed at different heights on the top of the frame 1, allowing for adjustment of the distance between the cutter 8 and the transmission belt 2 according to different slicing requirements, conditions, or types of fruit. This enables the cutter 8 to slice fruits of different thicknesses, improving the slicing effect of the device and further reducing the limitations of the device during use.

[0062] In this embodiment, a reverse displacement assembly is provided on the frame 1. When the cutter 8 contacts the fruit on the transmission belt 2, the reverse displacement assembly supports the transmission belt 2 to prevent it from deforming due to the downward pressure during cutting. The reverse displacement assembly includes a reverse gear 10, which is installed on the side wall of the frame 1; a pressure-resistant cylinder 37, which is connected through the bottom of the frame 1 and the two are slidably engaged; a pressure-resistant horizontal plate 38, which is installed on one end of the pressure-resistant cylinder 37; the pressure-resistant horizontal plate 38 is located at the bottom of the frame 1; a pressure-resistant rack 39 is installed on the pressure-resistant horizontal plate 38; the pressure-resistant rack 39 is meshed with the reverse gear 10; and a pressure-resistant square seat 40 is installed on the pressure-resistant cylinder 10. At the other end of column 37; pressure-resistant square seat 40 is located inside frame 1; the side wall of pressure-resistant square seat 40 is provided with a through directional slot 41; a directional sliding column 42 is installed in the directional slot 41; a directional base plate 43 is connected through the directional sliding column 42, and the two slide in fit; a pressure-resistant roller shaft 44 is installed on the side wall of the directional base plate 43; the pressure-resistant roller shaft 44 is located in the opening of the transmission belt 2, and the area of ​​the transmission belt 2 that bears the belt surface pressure is located at the moving path of the pressure-resistant roller shaft 44; a directional spring 45 is sleeved on the directional sliding column 42; one end of the directional spring 45 is fixedly connected to the directional slot 41, and the other end is fixedly connected to the directional base plate 43;

[0063] When the cutter 8 moves downwards to cut the fruit on the transmission belt 2, the displacement T-plate 5 drives the cutter 8 downwards, causing the displacement rack 22 on the displacement T-plate 5 to move downwards synchronously, engaging the reverse gear 10 to rotate. This causes the rack 39 to engage the anti-pressure rack 39 upwards, moving the anti-pressure horizontal plate 38 along the anti-pressure cylinder 37 at the bottom of the frame 1. This brings the anti-pressure horizontal plate 38 closer to the bottom of the frame 1, causing the anti-pressure square seat 40 on the anti-pressure cylinder 37 to move away from the bottom of the frame 1. The anti-pressure square seat 40 is equipped with an anti-pressure roller shaft 44, which is located inside the opening of the transmission belt 2. This movement of the anti-pressure square seat 40 synchronously drives the anti-pressure roller shaft 44 closer to and in contact with the area of ​​the transmission belt 2 that bears the belt surface pressure. This area is directly below the cutter 8, where the fruit is located. When the cutter 8 moves downwards, the anti-pressure roller shaft 44 moves upwards, indirectly contacting the bottom of the fruit to support it and prevent damage. When the cutter 8 applies pressure to the fruit to cut it into pieces, the pressure is transmitted to the transmission belt 2, causing it to deform and the fruit to move downwards under pressure. This results in the fruit not being completely cut into pieces, leading to a continuous cutting phenomenon. This improves the cutting effect of the device. The cutter 8 applies pressure to the anti-pressure roller shaft 44, preventing the fruit from being pressed down beyond the movement path of the cutter 8. This reduces the limitations of the device when cutting. The upward movement of the anti-pressure roller shaft 44 supports the fruit, ensuring that the movement path of the cutter 8 can completely cut the fruit into pieces. At the same time, the buffering force provided by the directional spring 45 can reduce the impact force caused by the fruit shaking on the anti-pressure roller shaft 44 during cutting, thereby improving the stability of the fruit cutting process and improving the cutting effect. It also prevents the cutter 8 from cutting too quickly and damaging the fruit, thus improving the quality of the fruit pieces and the consistency of the finished product's appearance and specifications.

[0064] This invention also provides an automated method for cutting dried fruit into pieces, comprising the following steps:
