Description

Technical Field

[0001] This invention relates to the field of post-harvest deep processing technology of fruits and vegetables, and in particular to a pomegranate calyx removal machine and its usage method. Background Technology

[0002] Pomegranates are a popular fruit among consumers as both food and medicine. Structurally, pomegranates mainly consist of pomegranate peel, pomegranate seeds, and calyx. The pomegranate peel can be used as a traditional Chinese medicine for internal and external consumption, while the seeds, which make up the main part of the pomegranate, can be eaten directly or processed into juice. When used on a small scale, the peel and seeds are usually removed manually. The process of peeling and seed extraction is inefficient. In batch processing and large-scale procurement for deep processing, mechanical removal methods are needed to improve efficiency. The first step in seed extraction is removing the pomegranate calyx to provide strong support for subsequent seed extraction. While some research has been conducted domestically and internationally on the pomegranate peeling and seed extraction process, some technical problems still need to be solved in the first step – removing the calyx. The main issues are work efficiency and effectiveness. This invention differs from the principles and processes currently used in pomegranate peeling and seed extraction. It fully analyzes the procedures, actions, and processes of removing the pomegranate calyx, combining mechanical and automatic control technologies, and making full use of pneumatic technology, stepper motors, and servo motor control technology. This effectively solves the technical problem of using machinery to replace manual calyx removal. Summary of the Invention

[0003] The purpose of this invention is to provide a pomegranate calyx removal machine, which uses electromechanical automation technology to automate the pomegranate calyx removal process.

[0004] To achieve the above objectives, the present invention discloses the following technical solution.

[0005] A pomegranate calyx removal machine, characterized in that its main components include a servo turntable assembly, a calyx removal stepper motor assembly, a synchronous pulley conveyor belt, and a collection bin containing the pomegranate and calyx after calyx removal;

[0006] The servo turntable assembly includes a servo motor 11, a motor bracket 12, an indexing turntable 4, a turntable support 10, and a turntable guard plate 14; the indexing turntable 4 is located directly above the turntable support 10, the output shaft of the servo motor 11 is connected to the turntable, and the turntable guard plate 14 is connected to the turntable support 10.

[0007] The decalyx removal stepper motor assembly includes: a decalyx removal motor assembly 6, a decalyx removal motor connected to the frame 5 by bolts, a cylindrical decalyx removal blade mounted at the front end of the screw, a calyx removal column 7 mounted on the frame and coaxial with the screw, a decalyx removal limiting cylinder 8 connected to a cylinder bracket 9 by bolts, a cylinder bracket 9 connected to the right side of the turntable support 10 by bolts, a feeding limiting cylinder 1 connected to the frame on the left side of the synchronous pulley conveyor belt 2 by bolts, and a contour pusher mounted at the front end of the cylinder piston rod, the main function of which is to push the pomegranate and ensure that the pomegranate smoothly enters the pomegranate feeding station on the turntable;

[0008] The synchronous pulley conveyor belt is placed on the left side of the servo turntable assembly. The conveyor belt has a grid groove for holding pomegranates, and its outlet is connected to the pomegranate inlet 15 to ensure that the pomegranates can correctly enter the pomegranate inlet 15 of the indexing turntable 4. The purpose of using a synchronous pulley conveyor belt is to facilitate accurate control of the motor's movement position and reduce the tensioning mechanism of ordinary belt drives.

[0009] The collection bin includes a collection bin 18, and a reversible rotating hopper 19 is connected to a stepper drive assembly 20 by welding. The purpose is to control the assembly to rotate 90 degrees in both directions via a stepper motor so that the pomegranate and calyx after calyx removal enter the right and left compartments of the collection bin, respectively. The stepper drive assembly 20 mainly consists of a stepper motor and an output shaft sleeve. The rotating hopper 19 is welded to the output shaft sleeve. The slide plate 21 is bolted to the side wall of the collection bin 18. The slide plate has a 45° tilt angle, which can buffer the vertical falling speed of the pomegranate and calyx, so that the calyx and pomegranate can smoothly enter the collection bin.

[0010] The present invention further discloses the following method of using the pomegranate calyx removal machine:

[0011] The pomegranates on the synchronous pulley conveyor belt 2 are arranged in an orderly manner on the dividing groove of the conveyor belt, with the calyx facing upwards. Under the action of the dividing groove upright plate and the conveyor belt, they move forward along the direction of the conveyor belt. When the control system detects that the first pomegranate has reached the pomegranate inlet of the indexing turntable 4, the conveyor belt stops moving, the piston rod of the feeding cylinder extends, and the front end of the contour pusher pushes the pomegranate into the pomegranate inlet 15 of the indexing turntable. Driven by the servo motor 11, it rotates 180° counterclockwise above the turntable support 10 to reach the calyx removal station 16. At this time, the indexing turntable stops moving, and the piston rod of the pomegranate calyx removal limiting cylinder 8 extends. A pomegranate-shaped limiting block at the front end clamps the pomegranate at the calyx removal station 16. At this time, the lead screw of the calyx removal screw motor assembly 6 directly above, driven by a stepper motor, drives the lower toothed cylindrical calyx removal blade in a downward linear and rotational motion. When the calyx removal blade contacts the pomegranate calyx, it is screwed into the pomegranate to a certain depth under the control of the stepper motor. Under the combined action of cutting and rotational forces, the calyx is squeezed into the hollow middle part of the calyx removal blade. At this point, the stepper motor reverses, driving the calyx removal blade, which has already had its calyx removed, to move upward. Simultaneously, the indexing turntable continues to rotate 90° counterclockwise, bringing the pomegranate with its calyx removed into the calyx removal stage. At the pomegranate collection station 17, a circular hole is located on the support plate. Pomegranates fall through this hole into the pomegranate collection bin 18. Due to the coordination of the process cycle, the pomegranates after calyx removal fall into the rotating hopper 19 in the collection bin. Driven by a stepper motor, the hopper rotates clockwise, pouring the pomegranates onto the sliding plate in the right bin. The pomegranates slide to the bottom of the right bin, completing the pomegranate collection process. At this time, the calyx removal stepper motor reverses, driving the calyx removal blade, which has already had its calyx removed, to move upward. When the calyx removal column contacts the calyx, because the calyx is moving upward under the action of the calyx removal blade, the calyx removal column pushes the calyx out, causing it to fall into the calyx removal station 1. At point 6, the indexing turntable rotates 90° counterclockwise to bring the removed sepals into the round hole of the pomegranate and sepal collection station 17. From there, the rotating hopper of the pomegranate collection chamber rotates counterclockwise under the drive of the stepper motor, pouring the sepals onto the slide plate of the left chamber. The sepals slide into the bottom of the left chamber, completing the sepal collection work. This completes the entire process of removing the sepals from the first pomegranate. Then, the indexing turntable continues to rotate 90° counterclockwise, and the synchronous wheel conveyor belt starts to send the second pomegranate into the pomegranate feed inlet, repeating the sepal removal process of the first pomegranate. This cycle continues, completing the continuous process of removing the sepals from the pomegranate.

[0012] The present invention, along with the disclosed method for using a pomegranate calyx removal machine, can effectively improve the efficiency of subsequent processes such as pomegranate peeling and seed extraction.

[0013] A more detailed description of the present invention:

[0014] This invention provides a pomegranate calyx removal machine, the main components of which include a servo turntable assembly, a calyx removal stepper screw motor assembly and a synchronous pulley conveyor belt, and a collection bin (for collecting the pomegranate and calyx after calyx removal).

[0015] Furthermore, the servo turntable assembly includes: a servo motor 11, a servo motor bracket 12, an indexing turntable 4, a turntable support 10, and a turntable guard plate 14. The indexing turntable 4 is directly above the turntable support 10, and the output shaft of the servo motor 11 is connected to the turntable. The turntable guard plate 14 is connected to the turntable support 10. The decalyx removal stepper screw motor assembly includes: a decalyx removal screw motor assembly 6, the decalyx removal screw motor and the frame 5 are connected by bolts, the front end of the screw is equipped with a cylindrical decalyx removal blade, and the decalyx removal column 7 is installed on the frame and coaxial with the screw. The decalyx removal limiting cylinder 8 and the cylinder bracket 9 are connected by bolts, and the cylinder bracket 9 is connected by bolts on the right side of the turntable support 10.

[0016] The feed limiting cylinder 1 is bolted to the frame on the left side of the synchronous pulley conveyor belt 2. A contour pusher is mounted at the front end of the cylinder piston rod, its main function being to push the pomegranates and ensure they smoothly enter the pomegranate feeding station on the turntable. The synchronous pulley conveyor belt is placed on the left side of the servo turntable assembly. The conveyor belt has compartments for holding pomegranates, and its outlet is connected to the pomegranate feed inlet 15 to ensure that the pomegranates can correctly enter the pomegranate feed inlet 15 of the indexing turntable 4. The synchronous pulley conveyor belt is placed on the left side of the servo turntable assembly, and its outlet is connected to the pomegranate feed inlet 15 to ensure that the pomegranates can correctly enter the pomegranate feed inlet 15 of the indexing turntable 4. Furthermore, the conveyor belt uses a synchronous pulley conveyor belt to facilitate accurate control of the motor's movement position and reduce the need for tensioning mechanisms in ordinary belt drives. The collection bin includes a collection bin 18, and a reversible rotating hopper 19 connected to the stepper drive assembly 20 by welding. The purpose is to control the assembly to rotate 90 degrees in both directions via a stepper motor so that the pomegranate and calyx after calyx removal enter the right and left separation bins of the collection bin, respectively. The stepper drive assembly 20 mainly consists of a stepper motor and an output shaft bushing. The rotating hopper 19 is welded to the output shaft bushing. The slide plate 21 is bolted to the side wall of the collection bin 18. The slide plate has a 45° tilt angle, which can buffer the vertical falling speed of the pomegranate and calyx, allowing the calyx and pomegranate to enter the collection bin smoothly.

[0017] This invention mainly solves the problem of automating the removal of calyxes during the peeling and seed extraction process of pomegranates. It focuses on the process of conveying, removing, separating and collecting calyxes through a mechanism. The main difficulty lies in the process of removing and separating pomegranate calyxes.

[0018] The advantages of the pomegranate calyx removal machine and its usage method disclosed in this invention compared with the prior art are as follows:

[0019] (1) The pomegranate calyx removal machine provided by the present invention can be controlled by the upper computer touch screen and the lower computer programmable controller PLC of the control system. By controlling the movement speed and precise stopping position of the synchronous pulley conveyor belt, the process of coordination with the servo turntable assembly and the calyx removal stepper screw motor assembly in the subsequent process is ensured, so as to ensure the smooth implementation and work efficiency of the entire calyx removal process. The pomegranate calyx removal machine is more operable in terms of speed and position accuracy control because it adopts servo motor driven indexing turntable. The calyx removal stepper screw motor assembly can accurately realize the calyx removal depth and reduce damage to pomegranate seeds. In summary, the combination of servo control technology, stepper motor control technology and synchronous belt drive technology can effectively improve the working accuracy, reliability and versatility of the equipment.

[0020] (2) The effect of removing the calyx of pomegranate can effectively remove the calyx of pomegranate, which can effectively improve work efficiency and achieve consistent calyx removal effect.

[0021] (3) The beneficial effects on the seed extraction process in the subsequent process: Because mechanical and automatic control technology is adopted, the calyx of the pomegranate can be effectively removed and the calyx and pomegranate are separated. This reduces the difficulty of separating the pomegranate peel in the subsequent seed extraction process and can improve the pomegranate seed acquisition rate. Attached Figure Description

[0033] Example 1

[0034] A pomegranate calyx removal machine is characterized by the following main components: a servo turntable assembly, a calyx removal stepper motor assembly, a synchronous pulley conveyor belt, and a collection bin (for collecting the pomegranate and calyx after calyx removal).

[0035] The servo turntable assembly includes a servo motor 11, a motor bracket 12, an indexing turntable 4, a turntable support 10, and a turntable guard plate 14; the indexing turntable 4 is located directly above the turntable support 10, the output shaft of the servo motor 11 is connected to the turntable, and the turntable guard plate 14 is connected to the turntable support 10.

[0036] The decalyx removal stepper screw motor assembly includes: a decalyx removal screw motor assembly 6, a decalyx removal screw motor connected to the frame 5 by bolts, a cylindrical decalyx removal blade mounted at the front end of the screw, a calyx removal column 7 mounted on the frame and coaxial with the screw, a decalyx removal limiting cylinder 8 connected to a cylinder bracket 9 by bolts, a cylinder bracket connected to the right side of the turntable support 10 by bolts, a feeding limiting cylinder 1 connected to the frame on the left side of the synchronous pulley conveyor belt 2 by bolts, and a contour pusher mounted at the front end of the cylinder piston rod, the main function of which is to push the pomegranate and ensure that the pomegranate smoothly enters the pomegranate feeding station on the turntable;

[0037] The synchronous pulley conveyor belt is placed on the left side of the servo turntable assembly. The conveyor belt has a grid groove for holding pomegranates, and its outlet is connected to the pomegranate inlet 15 to ensure that the pomegranates can correctly enter the pomegranate inlet of the indexing turntable 4. The purpose of using a synchronous pulley conveyor belt is to facilitate accurate control of the motor's movement position and reduce the tensioning mechanism of ordinary belt drives.

[0038] The collection bin includes a collection bin 18, and a reversible rotating hopper 19 is connected to a stepper drive assembly 20 by welding. The purpose is to control the assembly to rotate 90 degrees in both directions by the stepper motor so that the pomegranate and calyx after calyx removal can enter the right and left separation bins of the collection bin respectively. The stepper drive assembly 20 mainly consists of a stepper motor and an output shaft sleeve. The rotating hopper is welded to the output shaft sleeve. The slide plate 21 is bolted to the side wall of the collection bin. The slide plate has a 45° tilt angle, which can buffer the vertical falling speed of the pomegranate and calyx, so that the calyx and pomegranate can smoothly enter the collection bin.

[0039] Example 2

[0040] The pomegranate calyx removal machine operates as follows: Pomegranates on the synchronous pulley conveyor belt 2 are arranged in an orderly manner on the divider groove of the conveyor belt, with the calyx facing upwards. Under the action of the divider groove upright plate and the conveyor belt, the machine moves forward along the direction of the conveyor belt. When the control system detects that the first pomegranate has reached the pomegranate inlet of the indexing turntable 4, the conveyor belt stops moving, the piston rod of the feeding cylinder extends, and the front end of the piston rod pushes the pomegranate into the pomegranate inlet 15 of the indexing turntable. Driven by the servo motor 11, the machine rotates 180° counterclockwise above the turntable support 10 to remove the calyx. At the calyx removal station 16, the indexing turntable stops moving, and the piston rod of the pomegranate calyx removal limiting cylinder 8 extends. Due to the pomegranate limiting block at the front end, the pomegranate is clamped at the calyx removal station. At this time, the lead screw of the calyx removal lead screw motor assembly 6 directly above, driven by the stepper motor, drives the lower toothed cylindrical calyx removal blade to make downward linear and rotational movements. When the calyx removal blade contacts the pomegranate calyx, it can be screwed into the pomegranate to a certain depth under the control of the stepper motor. Under the combined action of cutting force and rotational force, the calyx is squeezed into the hollow middle part of the calyx removal blade. At this point, the stepper motor reverses, driving the calyx-removing knife, which has already had its calyx removed, to move upwards. Simultaneously, the indexing turntable continues to rotate 90° counterclockwise, bringing the pomegranates with their calyxes removed into the pomegranate collection station 17. A circular hole on the support plate allows the pomegranates to fall into the pomegranate collection bin 18. Due to the coordinated process cycle, the calyx-removed pomegranates fall into the rotating hopper 19 within the collection bin. Driven by the stepper motor, the hopper rotates clockwise, pouring the pomegranates onto the sliding plate in the right bin. The pomegranates slide to the bottom of the right bin, completing the pomegranate collection process. Meanwhile, the calyx-removing stepper motor... The machine reverses, causing the calyx-removing blade, which has already cut the sepals, to move upwards. When the calyx-removing column contacts the sepals, the upward movement of the sepals due to the blade pushes them out, causing them to fall at the calyx removal station. The indexing turntable then rotates 90° counterclockwise, carrying the removed sepals into the round hole of the pomegranate and calyx collection station. From there, the rotating hopper of the pomegranate collection bin, driven by a stepper motor, rotates counterclockwise, pouring the sepals onto the sliding plate of the left bin. The sepals slide to the bottom of the left bin, completing the calyx collection process. This completes the entire calyx removal process for the first pomegranate. The indexing turntable then continues to rotate 90° counterclockwise, and the synchronous conveyor belt starts, feeding the second pomegranate into the pomegranate feed inlet, repeating the calyx removal process for the first pomegranate. This cycle continues, completing the continuous calyx removal process for the pomegranate.

[0041] Example 3

[0042] Practical examples:

[0043] A pomegranate calyx removal machine is designed to automatically remove the calyxes of pomegranates, thereby reducing manual labor intensity and improving work efficiency.

[0044] Method: The pomegranate calyx removal machine needs to use a control system to realize the feeding, conveying, calyx removal, and collection of pomegranates and calyxes after calyx removal according to a certain rhythm and process steps.

[0045] Steps: First, place pomegranates in the slots on the synchronous conveyor belt, and replenish pomegranates according to the work rhythm. The control system gradually starts the servo motors of the synchronous conveyor belt and the indexing turntable, and extends or retracts the feed limit cylinder and calyx removal limit cylinder according to the process, completing the clamping function at different workstations. The starting, stopping, and forward / reverse rotation of the lead screw motor and the hopper stepper motor assembly need to be coordinated with the process to complete the calyx removal, separation, and collection of calyxes and pomegranates. The specific steps are as follows:

[0046] The servo motors of the synchronous conveyor belt and the indexing turntable are started. The feeding limit cylinder pushes the pomegranates in the grid slots of the synchronous conveyor belt to the feeding station of the indexing turntable. Driven by the indexing turntable, the pomegranates rotate 180° counterclockwise to the calyx removal station. At this time, the calyx removal limit cylinder extends and presses the pomegranates onto the station through the front limit block. The indexing turntable stops at this station under the control of the servo motor, waiting for the calyx removal process to be completed. At this time, the lead screw of the calyx removal lead screw motor assembly above it, driven by the stepper motor, drives the lower toothed cylindrical calyx removal knife to make linear and rotary movements. The calyx removal knife screws into the pomegranate to a certain depth, and the calyxes are squeezed into the hollow middle part of the calyx removal knife. The stepper motor reverses, driving the calyx removal knife to move upward. At the same time, the indexing turntable rotates 90° counterclockwise to bring the pomegranate with the calyxes removed into the calyx removal stage. At the pomegranate collection station, there is a round hole on the support plate. Pomegranates fall through this hole into the pomegranate collection bin. Due to the coordination of the process cycle, the pomegranates after calyx removal fall into the rotating hopper in the collection bin. Driven by a stepper motor, the hopper rotates clockwise, pouring the pomegranates onto the sliding plate of the right bin. The pomegranates slide to the bottom of the right bin, completing the pomegranate collection process. When the sepal removal column contacts the sepals, the sepals move upwards under the action of the sepal removal knife. Therefore, the sepal removal column pushes the sepals out, causing them to fall at the sepal removal station. The indexing turntable 4 then rotates 90° counterclockwise, bringing the removed sepals into the round hole of the pomegranate and sepal collection station. From here, the rotating hopper of the pomegranate collection bin rotates counterclockwise under the drive of a stepper motor, pouring the sepals onto the sliding plate of the left bin. The sepals slide to the bottom of the left bin, completing the sepal collection process. This completes the entire process of removing the calyx from the first pomegranate. Then, the indexing turntable continues to rotate 90° counterclockwise, and the synchronous conveyor belt starts to send the second pomegranate into the pomegranate feed inlet, repeating the calyx removal process of the first pomegranate. This cycle continues until the continuous removal of the calyx from the pomegranate is completed.

[0047] Results: The pomegranates with the calyx removed and the pomegranate calyxes were collected into the left and right compartments of the collection bin according to a certain production rhythm.

When the control system detects that the first pomegranate reaches the pomegranate feeding port (15) of the indexing turntable (4), the conveying belt stops moving, the feeding limit cylinder (1) extends, and the front end of the profiled push block pushes the pomegranate into the pomegranate feeding port (15) of the indexing turntable. Under the driving of the servo motor (11), the indexing turntable (4) rotates counterclockwise by 180° above the turntable support (10) to reach the calyx removing and removing station (16). At this time, the indexing turntable (4) stops moving, the piston rod of the calyx removing limit cylinder (8) extends, and the pomegranate is clamped in the calyx removing and removing station (16) due to the pomegranate limiting block at the front end. At this time, the lead screw of the calyx removing and removing cylinder motor assembly (6) above drives the lower end toothed cylindrical calyx removing knife to make downward linear motion and rotary motion under the driving of the stepping motor. When the calyx removing knife contacts the pomegranate calyx, it rotates into the pomegranate to a certain depth under the control of the stepping motor. The calyx is squeezed into the hollow part of the calyx removing knife under the combined action of the cutting force and the rotating force. At this time, the stepping motor is reversed to drive the calyx removing knife with the removed calyx to move upward. At the same time, the indexing turntable (4) continues to rotate counterclockwise by 90° to bring the pomegranate with the removed calyx into the processed pomegranate and calyx collecting station (17).

When the calyx removing column contacts the calyx, the calyx removing column pushes the calyx out and falls in the calyx removing and removing station (16). The indexing turntable (4) rotates counterclockwise by 90° to bring the removed calyx into the round hole of the processed pomegranate and calyx collecting station (17), and then into the rotating hopper of the collecting bin. The calyx is poured onto the slide plate (21) in the left partition bin under the driving of the stepping motor to complete the calyx collection work. Thus, the whole process of removing the calyx of the first pomegranate is completed. Then the indexing turntable (4) continues to rotate counterclockwise by 90°, the synchronous wheel conveying belt starts to send the second pomegranate into the pomegranate feeding port (15), and the process of removing the calyx of the first pomegranate is repeated. Thus, the continuous pomegranate calyx removing work process is completed.
