Description

Technical Field

[0001] This invention relates to the field of food processing machinery technology, specifically to an adaptive automatic pitting equipment for hawthorn. Background Technology

[0002] Hawthorn, a distinctive edible fruit in my country, plays an important role in the processing of dried fruit, candied fruit, beverages, and health foods. Pitting is a core pre-processing step in the industrial processing of hawthorn. Traditionally, hawthorn pitting relies mainly on manual labor, where workers use simple clamps or knives to remove the pits one by one. This manual pitting method is labor-intensive and results in inconsistent pitting quality.

[0003] With the development of automation in food processing machinery, some companies have begun to try to develop hawthorn pitting equipment. However, common hawthorn pitting equipment lacks the function of effectively identifying and correcting the posture of hawthorn fruits. During the feeding process, the posture of hawthorns is random and the orientation is not uniform. The equipment directly cuts the pits off the hawthorns, and it is difficult for the blade to be aligned with the optimal cutting position for the pit.

[0004] Studies have shown that the optimal pitting posture for hawthorn is when the fruit stalks are arranged vertically, i.e. Figure 11 The hawthorns shown are oriented along a vertical axis, allowing the cutting tool to precisely cut along the central axis of the pit, resulting in optimal pitting and the best preservation of the pulp. Existing equipment fails to adaptively adjust the hawthorn's posture, causing the pitting tool to deviate from the central axis of the pit. This leads to excessive cutting of the pulp, pit residue, or tearing of the pulp, directly affecting the yield and quality of the finished product.

[0005] Therefore, developing an automated processing equipment that can automatically correct the posture of hawthorns, achieve precise directional feeding, and remove pits with low breakage has become an urgent technical problem to be solved in this field.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0030] Each of the two crank units has a drive rod rotatably connected to one end of each drive rod, and the other end of each drive rod is connected to the same connecting rod.

[0031] Both sides of the connecting rod are slidably connected to the columns of the gantry frame through linear guide units;

[0056] 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.

[0057] See Figures 1-12 To address the problems mentioned in the background section, this invention provides an adaptive automatic pitting and processing device for hawthorn to solve the aforementioned technical problems. The technical solution is as follows:

[0058] An adaptive hawthorn automatic pitting processing device includes a frame 500 and a feeding mechanism 400, a straightening mechanism 200, a pitting mechanism 100 and a conveying mechanism 300 fixed on the frame 500.

[0059] The conveying mechanism 300 includes two rows of drive chains 310 mounted on the frame 500, and a plurality of anvils 320 fixed at intervals between the two rows of drive chains 310;

[0060] Each cutting board 320 is provided with multiple hawthorn positioning grooves 321. The bottom of the hawthorn positioning groove 321 is provided with a posture correction hole 322 that penetrates the cutting board 320. The bottom of the cutting board 320 is provided with a correction through groove 323 extending along the transmission direction of the transmission chain 310 below the posture correction hole 322.

[0061] The straightening mechanism 200 includes a U-shaped frame 210 fixed on the frame 500 and spanning the conveying mechanism 300, multiple straightening motors 220 mounted on the U-shaped frame 210, and a straightening cap 230 mounted on the main shaft end of the straightening motor 220; the straightening cap 230 is made of food-grade silicone hemispherical structure, which is flexible and wear-resistant and can avoid scratching the hawthorn skin.

[0062] The main shaft of the straightening motor 220 is set vertically, and the correction cap 230 can rotate with the main shaft of the straightening motor 220 and can pass through the correction slot 323 and extend into the attitude correction hole 322 to realize the attitude correction of hawthorn.

[0063] The feeding mechanism 400 is located on the feeding side of the conveying mechanism 300 and is used to quantitatively feed hawthorns into the hawthorn positioning groove 321 of the cutting board 320.

[0064] The pitting mechanism 100 is located on the discharge side of the conveying mechanism 300 and is used to pit the hawthorns in the hawthorn positioning groove 321.

[0065] It should be noted that the hawthorn positioning groove is used to provide stable limit and positioning support for individual hawthorns, so that the hawthorns are placed stably in an independent state, avoiding shaking, displacement or mutual interference during transportation, and providing a unified and reliable positioning basis for subsequent posture correction and accurate pitting.

[0066] The posture correction hole is located at the bottom of the hawthorn positioning groove and extends through the anvil. It provides a through-type insertion channel for the correction cap, allowing the correction cap to pass under the anvil and act directly on the bottom of the hawthorn, providing the necessary space and contact path for the rotational straightening action.

[0067] The correction channel extends along the conveying direction and is set at the bottom of the anvil. On the one hand, it provides a through clearance space for the correction cap, ensuring that the normal stepping conveying of the anvil does not interfere with the movement of the correction cap. On the other hand, it ensures that the correction cap can pass smoothly and make stable contact with the bottom of the hawthorn, so that the rotation and straightening action can be reliably executed and the posture correction effect can be stable and effective.

[0068] In this embodiment, an industrial camera is installed on the frame to capture images of hawthorns in the hawthorn positioning groove 321;

[0069] An industrial camera identifies feature points at the tail of a hawthorn fruit and compares these feature points with a standard upright posture. The standard upright posture includes a reference position where the hawthorn fruit stalk is vertically upward or downward.

[0070] When the tail feature point does not coincide with the standard upright posture, the industrial camera transmits the offset angle signal to the controller, which then controls the uprighting motor to achieve the uprighting of the hawthorn.

[0071] In this embodiment, the feeding mechanism 400 includes a feeding trough 410, a cylindrical housing 420, a feeding motor 430, and a distributing roller shaft 440;

[0072] The feeding trough 410 is fixedly installed on the frame 500, and the cylindrical shell 420 is fixedly connected to the bottom of the feeding trough 410;

[0073] The bottom of the feeding trough 410 is provided with multiple feeding holes 411 spaced apart, and the number and position of the feeding holes 411 correspond to the hawthorn positioning groove 321.

[0074] The dispensing roller shaft 440 is rotatably installed inside the cylindrical shell 420 along the axial direction. The outer wall of the dispensing roller shaft 440 is provided with a plurality of quantitative feeding grooves 441 spaced circumferentially.

[0075] The bottom of the cylindrical shell 420 is provided with multiple discharge holes 421, and the discharge holes 421 correspond one-to-one with the discharge holes 411;

[0076] The feeding motor 430 is fixedly installed at the end of the cylindrical housing 420, and the output shaft of the feeding motor 430 is drivenly connected to the distributing roller shaft 440.

[0077] In this embodiment, the core removal mechanism 100 includes a gantry frame 110, a bearing 131, a synchronizing rod 132, a crank unit 120, a drive rod 141, a connecting rod 142, and a core removal knife unit;

[0078] The gantry frame 110 is fixed across the conveyor mechanism 300;

[0079] The bearing seat 131 is fixed on the crossbeam of the gantry frame 110; the synchronizing rod 132 is rotatably connected to the bearing seat 131;

[0080] The crank unit 120 includes two sets. Each set of crank units 120 includes a crank one 121, a rod one 122 connected to the crank one 121, and a crank two 123 fixed to the other side of the rod one 122.

[0081] Two sets of crank units 120 are located on both sides of the bearing seat 131, and the cranks 123 of the two sets of crank units 120 are fixedly connected to both sides of the synchronizing rod 132.

[0082] One of the cranks 121 is driven by the de-core motor 170 fixed on the gantry frame 110; the other crank 121 is rotatably connected to the gantry frame 110.

[0083] Each of the two sets of crank units 120 has a drive rod 141 rotatably connected to its rod 122, and the other end of each drive rod 141 is connected to the same connecting rod 142.

[0084] Both sides of the connecting rod 142 are slidably connected to the columns of the gantry frame 110 through linear guide units;

[0085] The core removal knife unit includes a housing 140 fixed below the connecting rod and multiple core removal knives 160 fixed to the bottom of the housing 140; the core removal knife 160 is rod-shaped and has a cutting edge at its bottom.

[0086] In this embodiment, the two rows of transmission chains 310 are meshed and driven by a drive sprocket; the drive sprocket is driven by a transmission motor.

[0087] In this embodiment, the linear guide unit includes a guide rail 152 fixed on the column of the gantry frame 110, and a slider 151 that slides with the guide rail 152; the end of the connecting rod 142 is fixedly connected to the slider 151 on the same side.

[0088] In this embodiment, a position sensor is also included. The position sensor is installed on the frame 500 and is used to detect whether the hawthorn positioning groove 321 on the cutting board 320 is located at the pitting operation position of the pitting mechanism 100.

[0089] In this embodiment, the device further includes a controller, which is electrically connected to the feeding mechanism, the straightening mechanism, the core removal mechanism, the conveying mechanism, and the industrial camera, respectively, and is used to coordinate and control the operation of each mechanism.

[0090] An adaptive automatic pitting processing device for hawthorn provided in this embodiment of the invention includes the following steps:

[0091] (1) After the equipment is started, the controller coordinates the feeding mechanism, conveying mechanism, straightening mechanism, pitting mechanism and industrial camera to run automatically according to the set time sequence. The cleaned hawthorns are put into the feeding trough of the feeding mechanism by manual or upstream device. The feeding motor drives the distributing roller shaft to rotate. The quantitative dropping trough on the outer wall of the distributing roller shaft passes through the discharge hole at the bottom of the feeding trough in sequence, and the hawthorns are quantitatively fed into the dropping trough one by one. As the distributing roller shaft continues to rotate, the hawthorns in the dropping trough rotate to the discharge hole at the bottom of the cylindrical shell and fall under the action of gravity, accurately falling into the hawthorn positioning groove on the anvil of the conveying mechanism.

[0092] (2) The conveyor motor of the conveying mechanism drives the drive sprocket, which in turn drives two rows of transmission chains and multiple anvils fixed on them to move intermittently in a stepping manner. When the anvil reaches the straightening position, the position sensor sends a signal, and the conveying mechanism stops running. At this time, the industrial camera captures an image of the hawthorn in the hawthorn positioning groove and extracts the feature points of the hawthorn tail. The feature points are compared with the pre-stored standard upright posture (the stem is vertically up or down). If the tail feature points do not coincide with the standard posture, the sensor transmits the offset angle signal to the controller, and the controller controls the corresponding straightening motor in the straightening mechanism to start.

[0093] (3) The main shaft of the straightening motor drives the correction cap to rotate. The correction cap passes through the correction groove at the bottom of the anvil and extends into the posture correction hole, contacting the bottom of the hawthorn. The correction cap uses rotational friction to drive the hawthorn to rotate around its axis until the tail feature point of the hawthorn coincides with the standard upright posture. At this time, the axis of the fruit pit is precisely aligned with the cutting path of the subsequent pitting knife. The straightening motor stops, and the posture correction is completed.

[0094] (4) After the posture is straightened, the conveying mechanism starts again, moving the cutting board to the pitting station. After the position sensor detects that it is in position, the conveying mechanism stops. The controller starts the pitting motor, which drives the crank unit to rotate. Crank one drives crank two through rod one, and the synchronizing rod makes the crank units on both sides move synchronously. The crank unit drives the connecting rod to move vertically downward along the linear guide unit through the drive rod. The housing and multiple pitting knives fixed to the bottom of the connecting rod move downward synchronously. The blade at the bottom of the pitting knife accurately pierces the junction between the hawthorn pit and the pulp, pushing the pit downward. The pushed pit falls into the collection box 510 below the equipment, completing the pitting operation. Then the pitting motor continues to rotate, and the crank unit drives the connecting rod and the pitting knife assembly to return to their vertical position.

[0095] (5) After pitting, the conveying mechanism restarts, moving the cutting board towards the discharge side. A pulp collection box can be placed on the discharge side of the conveying mechanism in advance. After pitting, the pulp falls from the hawthorn positioning groove under gravity and into the pulp collection box. The cutting board continues to cycle back to the feeding station with the chain to start the next round of operation. The controller can adaptively adjust the rotation parameters of the straightening motor and the downward stroke of the pitting knife based on the size information fed back by the industrial camera to ensure accurate processing of hawthorns of different sizes. Throughout the process, the various mechanisms coordinate and link according to the timing set by the controller to realize continuous automated operation of hawthorns from feeding, posture recognition and straightening, accurate pitting to pulp collection.
