Description

Technical Field

[0001] The present invention relates to the technical field of workshop conveyors, in particular to a feeding system and method for frying sauces. Background Art

[0002] In the process of processing sauces in the factory, due to the increase in output and raw materials, it is often necessary to use a spiral elevator to add some hot pot ingredients, such as onions, ginger, garlic, fermented black beans, rock sugar, etc. After searching, the existing patent (publication number: CN220563813U) discloses a hot pot raw material spiral elevator, which specifically relates to the field of hot pot raw material processing, including a feeding tank, and a uniform feeding mechanism for the hot pot raw material spiral elevator is fixedly connected inside the feeding tank, and the uniform feeding mechanism includes a fixed plate, a feeding hole, an outer shell, a servo motor, a transmission shaft, a turntable, a feeding plate and an arc-shaped pressure plate; the present invention drives the transmission shaft to rotate by the servo motor inside the outer shell, and the transmission shaft drives the turntable to rotate, and the turntable drives the feeding plate and the arc-shaped pressure plate to rotate, and the hot pot raw materials fall along the feeding plate to one side of the arc-shaped pressure plate, and the arc-shaped pressure plate rotates to apply pressure to the raw materials, and press the raw materials down at a uniform speed from the feeding hole inside the fixed plate. In this way, pressure can be applied to the mixed hot pot raw materials at a uniform speed to prevent the hot pot raw materials from clogging the feeding hole, making the feeding smoother and more uniform, thereby improving the transmission and lifting effect of the device. In the process of realizing the present invention, the inventor found that the prior art has the following problems:

[0003] Since the mouth of the discharge tank is at a certain height from the ground or platform surface, when pouring the raw materials into the discharge tank, it is necessary to manually lift the container containing the weighed raw materials to a preset height and tilt and flip the container to pour the raw materials into the discharge pipe, which is time-consuming and labor-intensive. Although the existing technology can solve the above technical problems by lifting and flipping equipment, there are still the following defects: the existing integrated design of the lifting and flipping equipment and the hopper leads to a secondary feeding process, which increases the raw material loss rate. Summary of the Invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a feeding system and method for sauce frying, so as to realize the automatic lifting and flipping of raw materials, reduce the physical exertion of manual handling and dumping, and avoid the secondary feeding process of the traditional integrated hopper. It directly completes the whole process from weighing to lifting and flipping of raw materials, and reduces the scattering and waste of raw materials during the transportation process.

[0005] In one aspect, the present invention provides a feeding system for frying sauces, comprising a lifting module, the lifting module being arranged corresponding to a feeding barrel of a screw conveyor, the lifting module comprising:

[0006] Lifting and flipping unit;

[0007] The bucket car lifting unit is connected to the lifting and flipping unit, and the lifting and flipping unit drives the bucket car lifting unit to rise and fall. The bucket car lifting unit includes a bucket car frame and a bucket car fixing device. The bucket car frame has a bucket car frame entrance for the bucket car unit to enter and exit on the side away from the spiral conveyor. The bucket car fixing device is fixedly installed in the bucket car frame on the side away from the bucket car frame entrance;

[0008] The bucket car unit includes a moving part and a hopper, the hopper is fixed on the moving part, and a locking rod is fixed on one side of the hopper corresponding to the bucket car fixing device. When the bucket car unit fully enters the bucket car frame in a preset direction, the locking rod is clamped and fixed by the bucket car fixing device.

[0009] This invention achieves automated lifting, tilting, and feeding of raw materials through the synergistic effect of a lifting and tilting unit and a hopper hoisting unit, reducing the physical effort of manual handling and dumping and improving production efficiency. The hopper unit adopts a detachable design, eliminating the secondary feeding process required by traditional integrated hoppers. It directly completes the entire process from weighing to lifting and tilting, reducing material scattering and waste during transportation. The clamping structure of the locking rod and the fixing device improves stability during feeding.

[0010] Furthermore, the bucket car fixing device includes:

[0011] A mounting portion, the mounting portion being fixedly mounted on the bucket truck frame;

[0012] a first connecting rod, wherein the first connecting rod is provided with two groups, and the two groups of the first connecting rods are arranged opposite to each other, one end of the first connecting rod is pivotally connected to the mounting portion, and a clamping block is pivotally mounted on the other end of the first connecting rod, and the side of the clamping block that contacts the locking rod is matched with the locking rod portion;

[0013] A sliding block is provided between the two sets of the first connecting rods. The middle portion of the first connecting rod is movably connected to the sliding block via the second connecting rod. A pushing portion is fixed to the sliding block near the surface of the clamping block, and the surface of the pushing portion matches the locking rod portion.

[0014] a second rack fixed to a surface of the sliding block away from the pushing portion, the second rack integrally passing through the mounting portion and slidingly engaged with the mounting portion, an elastic member being sleeved on a portion of the second rack between the sliding block and the mounting portion;

[0015] a second gear mounted in the mounting portion and meshing with the second rack;

[0016] A self-locking component is connected to the second gear.

[0017] Furthermore, the self-locking component includes:

[0018] a ratchet wheel, the ratchet wheel being coaxially mounted in the mounting portion with the second gear;

[0019] a pawl, the pawl being mounted in the mounting portion corresponding to the ratchet and cooperating with the ratchet;

[0020] The second power device is installed in the installation part. The second power device is connected to the pawl through two groups of third connecting rods. The two groups of third connecting rods are connected end to end, and elastic parts are installed on the connecting shafts of the two groups of third connecting rods.

[0021] Through the linkage design of the pushing part and the sliding block, combined with the rack-gear transmission and the ratchet-pawl self-locking structure, the bucket unit can be automatically clamped and released, reducing manual intervention and improving operating efficiency. The one-way rotation characteristics of the ratchet are combined with the pawl release function driven by the power unit to prevent accidental reversal and quickly unlock to meet the needs of complex working conditions.

[0022] Furthermore, the lifting and flipping unit includes:

[0023] a stand, on the upper portion of which a first rack is fixedly mounted;

[0024] A first power device, the first power device is fixedly mounted on the stand;

[0025] The slide is slidably mounted on the vertical frame and is driven to move vertically linearly by the first power device. A rotating shaft is rotatably mounted on the slide, and a connecting plate is fixed to one end of the rotating shaft. The connecting plate is fixed to the bucket frame, and a first gear matching the first rack is mounted on the rotating shaft corresponding to the first rack.

[0026] The slide is driven to move linearly along the vertical frame by the first power device. When the slide moves to the second preset height, the first gear on the rotating shaft engages with the rack of the vertical frame, automatically driving the bucket frame to flip when the slide is raised or lowered, thereby realizing automatic lifting and flipping of the bucket unit.

[0027] Furthermore, a limiting plate fixedly mounted on the slide is provided below the connecting plate.

[0028] When the bucket frame returns to a horizontal state, the limit plate provides a mechanical stop function to prevent equipment collision caused by over-turning.

[0029] Furthermore, the lifting module also includes a knocking unit, which is installed as a whole on the slide, and the bucket car in the bucket car frame is knocked by the knocking unit.

[0030] Furthermore, the knocking unit includes:

[0031] a third power device, the third power device being fixedly mounted on the slide;

[0032] The turntable is driven to rotate along its own circumference by a third power device;

[0035] The guide cylinder is fixedly mounted on the slide and is sleeved on the outside of the knocking rod and maintains a sliding fit with the knocking rod.

[0036] The third power device drives the turntable to rotate through mechanical transmission. The turntable and the eccentrically installed connecting rod mechanism convert the rotational motion into linear motion of the knocking rod to knock the hopper, thereby causing the hopper to vibrate at a preset frequency to knock off the raw materials attached to the inner wall of the hopper, reduce the amount of material residue on the inner wall of the hopper car, and reduce the raw material loss rate.

[0037] Furthermore, the feeding system further includes a control module, which is used to:

[0038] Obtain bucket frame weight data, bucket frame height data, bucket frame angle data and raw material category in real time;

[0039] The climbing of the bucket frame is judged based on the bucket frame height data at adjacent time nodes;

[0040] If the bucket frame is climbing, compare the bucket frame height data with the flip start height;

[0041] If the bucket car height data is less than the flip start height, the control module outputs a first speed control signal to the lifting and flipping unit to make the first power device in the lifting and flipping unit output a first speed;

[0042] If the bucket car height data is greater than or equal to the flip start height, the flip stage is judged according to the bucket car frame angle data to obtain the flip stage judgment result;

[0043] Calculate the bucket frame flipping speed based on the flipping stage judgment result to obtain the bucket frame flipping speed calculation result; calculate the second speed based on the bucket frame flipping speed calculation result to obtain the second speed calculation result;

[0044] Perform dynamic compensation calculation on the second speed calculation result according to the bucket car frame weight data and the raw material category to obtain the second speed compensation calculation result;

[0045] Outputting a second speed control signal to the lifting and flipping unit according to the second speed compensation calculation result, so that the first power device in the lifting and flipping unit outputs the second speed;

[0046] If the bucket frame is descending, the control module outputs a third speed control signal to the lifting and flipping unit, so that the first power device in the lifting and flipping unit outputs a third speed.

[0047] Furthermore, the method for calculating the bucket frame turning speed based on the turning stage judgment result is as follows:

[0048] ;

[0049] in, v is the calculation result of the bucket frame turning speed, in meters per second; v 0 is the initial flip speed, in meters per second; e is a natural constant; K 1 is the starting coefficient; K 2 is the acceleration factor; K 3 is the first reduction coefficient; K 4 is the second reduction coefficient; v 1 is the maximum flip speed, in meters per second; i Real-time flip angle for bucket frame; i 1. i 2. i 3. i 4. i 5 are the preset angle thresholds for judging the flipping stage.

[0050] A multi-stage speed control strategy uses flexible acceleration during the initial rollover phase to reduce splashing during material dumping. This, combined with speed control in the remaining stages, improves material dumping uniformity. A triple-parameter compensation mechanism based on weight, angle, and material type allows the system to adapt to the dynamic characteristics of materials of varying densities.

[0051] On the other hand, the present invention also provides a method for feeding sauce frying, which uses the above-mentioned feeding system for frying sauce, and the feeding method includes:

[0052] Pushing the bucket car unit onto the bucket car frame, wherein the hopper of the bucket car unit is loaded with a single raw material that has been weighed in the weighing area;

[0053] When the bucket car unit is pushed to the first preset position, the locking rod on the side of the hopper contacts the pushing part, and the bucket car unit continues to be pushed. The locking rod will push the pushing part of the bucket car fixing device to move inward, and the movement of the pushing part will drive the sliding block to move inward, and the two groups of the first connecting rods are pulled by the second connecting rod to rotate, so as to continuously approach the locking rod until the clamping blocks installed at the ends of the two groups of the first connecting rods clamp the locking rod. When the sliding block moves inward, the second rack will also move inward, driving the second gear to rotate, and the ratchet drives them to rotate in the same direction. When the ratchet rotates, the sliding surface of its ratchet teeth will push the tip of the pawl, forcing the pawl to overcome the elastic member and lift up and slide through the tooth groove of the ratchet. Due to the action of the elastic member, the pawl falls into and gets stuck on the driving surface of the current ratchet tooth, locking the ratchet in the current position and preventing it from reversing. When the bucket car unit is pushed to the second preset position, the bucket car unit is completely fixed on the bucket car frame, and the system is started;

[0054] The first power device drives the bucket car frame to rise. When the bucket car frame rises to a second preset height, the gear and the rack begin to mesh. The first power device continues to drive the bucket car frame to rise. Under the transmission action of the gear and rack, the bucket car frame rotates, driving the bucket car unit to flip, so as to tilt the raw materials in the bucket car unit into the storage hopper of the screw conveyor above the wok;

[0055] After the flipping is completed, the third power device will drive the turntable to rotate, and through the transmission action of the fourth connecting rod, the knocking rod will move back and forth linearly, continuously knocking the bucket unit at a preset frequency to shake off the raw materials attached to the bucket unit;

[0056] After unloading is completed, the first power device drives the bucket frame to descend. Under the transmission action of the gear rack, the bucket frame rotates in the opposite direction to reset and continues to descend to the lowest height;

[0057] When it descends to the lowest height, the second power device drives the pawl to rotate so that the pawl leaves the ratchet tooth groove. At this time, the bucket unit is pulled outward. Under the action of the elastic member, the pushing part moves outward. The movement of the pushing part drives the sliding block to move outward. The second connecting rod pushes the two groups of the first connecting rods to rotate, so as to continuously move away from the locking rod, thereby releasing the bucket unit. The bucket unit is then pulled again until the bucket unit leaves the bucket frame, and this process is repeated.

[0058] When the first power device is working, the control module will obtain the bucket car frame weight data, bucket car frame height data, bucket car frame angle data and raw material category in real time; the bucket car frame climbing judgment is performed based on the bucket car frame height data of adjacent time nodes. If the bucket car frame is climbing, the bucket car frame height data is compared with the flip starting height; if the bucket car height data is less than the flip starting height, the control module outputs a first speed control signal to the lifting and flipping unit to make the first power device in the lifting and flipping unit output a first speed; if the bucket car height data is greater than or equal to the flip starting height, the flip stage judgment is performed based on the bucket car frame angle data, and the flip stage judgment result is obtained. The bucket frame flipping speed is calculated based on the transition stage judgment result to obtain the bucket frame flipping speed calculation result, and the second speed calculation is performed based on the bucket frame flipping speed calculation result to obtain the second speed calculation result; the second speed calculation result is dynamically compensated based on the bucket frame weight data and the raw material category to obtain the second speed compensation calculation result; a second speed control signal is output to the lifting and flipping unit based on the second speed compensation calculation result, so that the first power device in the lifting and flipping unit outputs the second speed; if the bucket frame is descending, the control module outputs a third speed control signal to the lifting and flipping unit, so that the first power device in the lifting and flipping unit outputs the third speed;

[0059] The method for calculating the bucket frame turning speed based on the turning stage judgment result is as follows:

[0060] ;

[0061] in, v is the calculation result of the bucket frame turning speed, in meters per second; v 0 is the initial flip speed, in meters per second; e is a natural constant; K 1 is the starting coefficient; K 2 is the acceleration factor; K 3 is the first reduction coefficient; K 4 is the second reduction coefficient; v 1 is the maximum flip speed, in meters per second; i Real-time flip angle for bucket frame; i 1. i 2. i 3. i 4. i 5 are the preset angle thresholds for judging the flipping stage.

[0062] The present invention has the following advantages:

[0063] This invention achieves automated lifting, tilting, and feeding of raw materials through the synergistic effect of a lifting and tilting unit and a hopper hoisting unit, reducing the physical effort of manual handling and dumping and improving production efficiency. The hopper unit adopts a detachable design, eliminating the secondary feeding process required by traditional integrated hoppers. It directly completes the entire process from weighing to lifting and tilting, reducing material scattering and waste during transportation. The clamping structure of the locking rod and the fixing device improves stability during feeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0086] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0087] As described in the background technology, since the mouth of the discharge tank is at a certain height from the ground or platform surface, when pouring the raw materials into the discharge tank, it is necessary to manually lift the container containing the weighed raw materials to a preset height and tilt and flip the container to pour the raw materials into the discharge pipe, which is time-consuming and labor-intensive. Although the existing technology can solve the above technical problems by lifting and flipping equipment, the following defects still exist: the existing integrated design of the lifting and flipping equipment and the hopper leads to a secondary feeding process, which increases the raw material loss rate.

[0088] Example 1:

[0089] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a feeding system and method for sauce frying, so as to realize the automatic lifting and flipping of raw materials, reduce the physical exertion of manual handling and dumping, and avoid the secondary feeding process of the traditional integrated hopper, and directly complete the whole process from weighing to lifting and flipping of raw materials, thereby reducing the scattering and waste of raw materials during the transportation process.

[0090] like Figure 1 、 Figure 9 As shown, the feeding system includes a lifting module 20, which is arranged corresponding to the feeding barrel of the screw conveyor, and the lifting module includes:

[0091] Lifting and turning unit 100;

[0092] The bucket car lifting unit 200 is connected to the lifting and flipping unit, and the lifting and flipping unit drives the bucket car lifting unit to lift and flip. Figure 3 As shown, the bucket car lifting unit includes a bucket car frame 210 and a bucket car fixing device 220. The bucket car frame has a bucket car frame entrance for the bucket car unit to enter and exit on the side away from the spiral conveyor. The bucket car fixing device is fixedly installed in the bucket car frame away from the bucket car frame entrance.

[0093] Bucket unit 400, such as Figure 9 As shown, the bucket car unit includes a moving part 430 and a hopper 420. The hopper is fixed on the moving part. A locking rod 440 is fixed on one side of the hopper corresponding to the bucket car fixing device. When the bucket car unit fully enters the bucket car frame in a preset direction, the locking rod is clamped and fixed by the bucket car fixing device.

[0094] Specifically, the bucket car unit is weighed and loaded with a preset weight of raw materials in the weighing area in advance. After the weighing is completed, the bucket car unit is manually pushed to the frying area, and the bucket car unit is pushed from the bucket car frame entrance to the bucket car addition with the preset locking rod facing the bucket car fixing device. When the bucket car unit completely enters the bucket car frame, the locking rod is clamped by the bucket car fixing device to complete the fixation of the bucket car unit. Then the system is started, and the lifting and flipping unit first drives the bucket car unit to climb. After climbing to the preset height, the bucket car frame gradually flips, and the bucket car unit also flips accordingly to pour the raw materials into the screw conveyor.

[0095] This embodiment achieves automated lifting, tilting, and feeding of raw materials through the synergistic effect of the lifting and tilting unit and the bucket lifting unit, reducing the physical effort of manual handling and dumping, and improving production efficiency. The bucket unit adopts a detachable design, eliminating the secondary feeding process required by traditional integrated hoppers. The entire process from weighing to lifting and tilting of raw materials is completed directly, reducing material scattering and waste during transportation. The clamping structure of the locking rod and the fixing device improves stability during feeding.

[0096] In this embodiment, if Figure 9 As shown, the movable portion can be a frame with rollers at the bottom. A push handle 410 can be provided on the side of the movable portion away from the locking rod, and the entire bucket unit can be pushed by holding the push handle. In addition, the screw conveyor in this embodiment can be horizontally arranged above the stir-frying equipment, with the discharge port of the screw conveyor corresponding to the feed port of the stir-frying equipment. This system corresponds to the discharge tank of the screw conveyor. When the bucket unit is turned over, the raw materials in the hopper are poured into the discharge tank through the feed port at the top of the discharge pipe.

[0097] In this embodiment, if Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the bucket car fixing device may include:

[0098] The mounting portion 221 is fixedly mounted on the bucket frame and can be a hollow shell;

[0099] A first connecting rod 222 is provided in two groups, the two groups of first connecting rods being arranged opposite each other. One end of the first connecting rod is pivotally connected to the mounting portion, and a clamping block 224 is pivotally mounted on the other end of the first connecting rod. The side of the clamping block that contacts the locking rod partially matches the locking rod.

[0100] A sliding block 226 is provided between the two sets of the first connecting rods. The middle portion of the first connecting rod 222 is movably connected to the sliding block via the second connecting rod 225. A pushing portion 223 is fixed to the sliding block near the surface of the clamping block, and the surface of the pushing portion matches the locking rod portion.

[0101] A second rack 227 is fixed to the surface of the sliding block away from the pushing portion. The second rack extends entirely through the mounting portion and slides with the mounting portion. An elastic member is mounted on the portion of the second rack between the sliding block and the mounting portion.

[0102] a second gear 229 mounted in the mounting portion and meshing with the second rack;

[0103] The self-locking component 228 is connected to the second gear.

[0104] Optionally, the self-locking component includes:

[0105] a ratchet 228C, the ratchet being coaxially mounted within the mounting portion with the second gear;

[0106] a pawl 228B, which is mounted in the mounting portion corresponding to the ratchet and cooperates with the ratchet;

[0107] The second power device 228A is installed in the installation part. The second power device is connected to the pawl through two sets of third connecting rods 228D. The two sets of third connecting rods are connected end to end, and elastic parts are installed on the connecting shafts of the two sets of third connecting rods.

[0108] Specifically, when the bucket car unit is pushed to the first preset position, the locking rod on the side of the hopper contacts the pushing part and continues to push the bucket car unit. The locking rod will push the pushing part of the bucket car fixing device to move inward, and the movement of the pushing part will drive the sliding block to move inward. The two groups of the first connecting rods are pulled to rotate by the second connecting rod to continuously approach the locking rod until the clamping blocks installed at the ends of the two groups of the first connecting rods clamp the locking rod. When the sliding block moves inward, the second rack will also move inward, driving the second gear to rotate, and the ratchet drives them to rotate in the same direction. When the ratchet rotates, the sliding surface of its ratchet teeth will push the tip of the pawl, forcing the pawl to overcome the elastic member and lift up and slide across the tooth groove of the ratchet. Due to the action of the elastic member, the pawl falls into and gets stuck on the driving surface of the current ratchet tooth, locking the ratchet in the current position and preventing it from reversing. When the bucket car unit is pushed to the second preset position, the bucket car unit is completely fixed on the bucket car frame. The pawl is driven to rotate by the second power device to make the pawl leave the ratchet tooth groove. At this time, the bucket unit is pulled outward. Under the action of the elastic member, the pushing part will move outward, and the sliding block is driven to move outward by the movement of the pushing part. The two groups of the first connecting rods are pushed to rotate through the second connecting rod to continuously move away from the locking rod, release the bucket unit, and continue to pull the bucket unit until the bucket unit leaves the bucket frame.

[0109] This embodiment realizes automatic clamping and release of the bucket unit through the linkage design of the pushing part and the sliding block, combined with the rack-gear transmission and the ratchet-pawl self-locking structure, reducing manual intervention and improving operating efficiency. The one-way rotation characteristic of the ratchet is combined with the pawl release function driven by the power device, which not only prevents accidental reversal but also enables rapid unlocking to meet the needs of complex working conditions.

[0110] In this embodiment, the second power device includes, but is not limited to, a small device such as a micro-electric cylinder or a micro-motor capable of driving the pawl to rotate. The elastic member may be a spring. Furthermore, a stopper may be provided at the end of the rack. A stepped surface is formed between the stopper and the rack, forming a mechanical stop or interface with the outer wall of the mounting portion.

[0111] In addition, in addition to the above-mentioned structure recorded in this embodiment, the bucket car fixing device can also be other devices that can achieve the fixation of the bucket car unit. For example, electric cylinders, air cylinders or hydraulic cylinders are set on both sides of the bucket car frame, and a plate or block is driven to press the two sides of the hopper of the bucket car unit tightly. However, this method is easy to squeeze and deform the side walls of the hopper.

[0112] In this embodiment, if Figure 2 As shown, the lifting and flipping unit may include:

[0113] A stand 130 , on the upper portion of which the first rack 120 is fixedly mounted;

[0114] A first power device 110, which is fixedly mounted on the stand;

[0115] The slide 150 is slidably mounted on the vertical frame and is driven to move vertically linearly by the first power device. A rotating shaft 154 is rotatably mounted on the slide, and a connecting plate 152 is fixed to one end of the rotating shaft. The connecting plate is fixed to the bucket frame, and a first gear 151 matching the first rack is mounted on the rotating shaft corresponding to the first rack.

[0116] Specifically, the bucket car frame is driven to rise by the first power device. When the bucket car frame rises to a second preset height, the gear and rack begin to mesh, and the first power device continues to drive the bucket car frame to rise. Under the transmission action of the gear rack, the bucket car frame rotates, driving the bucket car unit to flip over, so as to tilt the raw materials in the bucket car unit into the storage hopper of the screw conveyor above the wok. After unloading is completed, the first power device drives the bucket car frame to descend. Under the transmission action of the gear rack, the bucket car frame rotates in the opposite direction to reset, and continues to descend to the lowest height.

[0117] In this embodiment, the slide is driven to move linearly along the vertical frame by the first power device. When the slide moves to the second preset height, the first gear on the rotating shaft engages with the rack of the vertical frame, and automatically drives the bucket frame to flip when the slide is raised or lowered, thereby realizing automatic lifting and flipping of the bucket unit. The structure is simple and easy to maintain.

[0118] In this embodiment, the first power device can be a servo motor or a stepper motor. A screw can be installed on the vertical frame. The screw is connected to the first power device and engages with the slide through a thread. The first power device drives the screw to rotate, thereby causing the slide to move vertically linearly. In addition to the above-mentioned motor-screw structure, other structures can also be used, such as a motor-sprocket structure or a motor-pulley structure. In addition, the slide can be slidably engaged with the guide rod 140 fixed to the vertical frame via a slider. Of course, in addition to the slider-guide rod structure, a slider-guide rail structure can also be used.

[0119] In this embodiment, a limit plate 153 fixedly mounted on the slide can also be provided below the connecting plate. When the bucket frame returns to a horizontal state, the limit plate provides a mechanical stop function to prevent equipment collision caused by overturning.

[0120] Example 2:

[0121] When pouring raw materials into the screw conveyor, due to the characteristics of the raw materials themselves, a small amount of raw materials may adhere to the inner wall of the hopper, such as fermented black beans. Therefore, in order to reduce the amount of raw materials attached and avoid the waste of raw materials, this embodiment optimizes a feeding system for stir-frying sauces proposed in the embodiment, such as Figure 1 As shown, in addition to the structure described in Example 1, the lifting module in this embodiment may further include a knocking unit 300, which is integrally mounted on the slide, and is used to knock the bucket in the bucket frame.

[0122] like Figure 8 As shown, the knocking unit may include:

[0123] a third power device, the third power device being fixedly mounted on the slide;

[0124] The turntable 310 is driven by a third power device to rotate along its own circumference;

[0125] A fourth connecting rod 320, one end of which is eccentrically mounted on the surface of the turntable;

[0126] a knocking rod 330, one end of which is pivotally connected to an end of the fourth connecting rod away from the rotating disk;

[0127] The guide cylinder 340 is fixedly mounted on the slide and is sleeved on the outside of the knocking rod and maintains a sliding fit with the knocking rod.

[0128] In this embodiment, the turntable is driven to rotate by the third power device. Since the fourth connecting rod is eccentrically installed on the surface of the turntable, when the turntable rotates, the knocking rod is caused to move back and forth linearly through the transmission of the fourth connecting rod and the movement guidance of the guide cylinder, thereby continuously knocking on the hopper to shake out the raw materials attached to the inner wall of the hopper by knocking.

[0129] The third power device drives the turntable to rotate through mechanical transmission. The turntable and the eccentrically installed connecting rod mechanism convert the rotational motion into linear motion of the knocking rod to knock the hopper, thereby causing the hopper to vibrate at a preset frequency to knock off the raw materials attached to the inner wall of the hopper, reduce the amount of material residue on the inner wall of the hopper car, and reduce the raw material loss rate.

[0130] In this embodiment, the third power device includes but is not limited to a servo motor, a stepper motor, or other device capable of driving the turntable to rotate. In addition, it can also be directly connected to the knocking rod through a device capable of achieving linear motion of parts such as a cylinder, an electric cylinder, a hydraulic cylinder, etc. In addition, a buffer block can be fitted on the end of the knocking rod. The buffer block is made of an elastic and relatively soft material, such as rubber. In addition, the knocking rod can also include a barrel and a rod. The barrel is fitted on the outside of the rod, one end of the rod extends out of the barrel, and one end of the rod located in the barrel is connected to the barrel through an elastic member. When the rod contacts the hopper, it will retract inward to cushion the impact, so as to avoid the rod from hard hitting the hopper and reduce deformation of the hopper structure.

[0131] Example 3:

[0132] This embodiment is proposed based on a lifting and flipping unit of a motor-screw transmission structure.

[0133] When the lifting and flipping unit drives the bucket car lifting unit to move, since its rotation speed is relatively constant, the bucket car unit may flip over at the moment of flipping due to excessive rotation speed, causing the raw materials to pour out of the discharge tank. Although the existing technology can adjust the movement speed of the bucket car unit by controlling the output power of the motor, the control strategy is relatively simple and it is difficult to dynamically adjust the rotation speed according to actual conditions.

[0134] Therefore, in order to solve the above technical problems, this embodiment proposes improvements based on embodiments 1 to 3, such as Figure 10 As shown, in addition to the structures described in Examples 1 to 3, the feeding system in this embodiment may further include a control module 30, which is used to:

[0142] Outputting a second speed control signal to the lifting and flipping unit according to the second speed compensation calculation result, so that the first power device in the lifting and flipping unit outputs the second speed;

[0143] If the bucket frame is descending, the control module outputs a third speed control signal to the lifting and flipping unit, so that the first power device in the lifting and flipping unit outputs a third speed.

H t With flip start height H 0 For comparison, if H t < H 0 , the bucket frame has not reached the turning start height; if H t ≥ H 0 , the bucket frame reaches the turning start height;

H t With flip start height H 0 For comparison, if H t < H 0 , the bucket frame has not reached the turning start height; if H t ≥ H 0 , the bucket frame reaches the turning start height;
