Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product processing automation, and specifically to a fully automatic profiling production system for agricultural product processing. Background Art

[0002] In the deep processing field of specific agricultural products, the shaping of the material form, as a key production process link, directly affects the stability of the product form characteristics and physical properties, and further determines the market acceptance of the end product. The traditional production method relies on manual labor to complete processes such as material positioning and shaping, and there are problems such as low operation efficiency and fluctuations in product qualification rates caused by insufficient standardization. With the rapid development of science and technology and the increasing maturity of automation technology, this field is gradually moving towards the upgrading path of automation and intelligence.

[0003] Although the existing automated forming systems have built a basic transportation circulation system, there are still some deficiencies:

[0004] 1) Low space utilization rate: Using a loop conveyor layout, it is necessary to complexly connect multiple conveyor modules in series, resulting in a large floor area of the equipment and limited expandability of the production line;

[0005] 2) Poor production continuity: The transportation carrier and the main conveyor line adopt a separated design, and secondary positioning connection is required at multiple process nodes, resulting in the interruption of the production rhythm and difficulty in meeting the requirements of high-speed continuous production;

[0006] 3) Poor thermal processing efficiency: The heating equipment uses drum conveyor and heating tube radiation heating, with low heating efficiency, long heating stroke, high energy consumption, and lack of humidity control, which easily leads to hardening of the material surface layer;

[0007] 4) The manual participation links have not been eliminated: The feeding and discharging links rely on manual intervention, and it is difficult to achieve true full-process automation, restricting the improvement of production capacity and yield. Summary of the Invention

[0008] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a fully automatic profiling production system for agricultural product processing, which improves production efficiency, product quality and space utilization rate, and enhances production continuity and automation degree.

[0009] The technical solution adopted by the present invention is as follows: A fully automatic profiling production system for agricultural product processing, including a circulating conveying mechanism, a feeding mechanism, a material sorting mechanism, a heating and softening mechanism, a profiling mechanism, and a discharging mechanism arranged in sequence along the conveying direction of the circulating conveying mechanism;

[0010] The circulating conveying mechanism includes a carrier moving guide rail composed of two groups of symmetrically arranged track pairs, a front-end driving device and a tail-end driving device respectively arranged at the head and tail ends of the carrier moving guide rail, and a plurality of carriers circulating along the carrier moving guide rail;

[0011] The vehicle includes a number of parallel strip-shaped bearing bars. Both ends of each strip-shaped bearing bar are fixedly connected to the vehicle traction chains on both sides through connecting seats, and there is a gap between two adjacent connecting seats on the same side. A plurality of independent material supporting units are evenly distributed along the length direction on the strip-shaped bearing bar. The material supporting units are arranged in a multi-row and multi-column array on the vehicle. Each of the material supporting units is provided with a sunken cavity for accommodating a single to-be-processed material. The vehicle traction chains on both sides are respectively in sliding fit with two sets of track pairs of the vehicle moving guide rail;

[0012] Both the front-end driving device and the tail-end driving device include two sets of juxtaposed chain drive assemblies. Each set of chain drive assemblies includes a sprocket and a drive chain connecting the sprockets. The sprockets at corresponding positions of the two sets of chain drive assemblies are connected by a transmission shaft to achieve synchronous transmission; equally spaced push rods are fixedly connected to the drive chain. The arrangement spacing of the push rods matches the gap of the vehicle connecting seat. When the drive chain operates, the push rods are inserted into the gap between adjacent connecting seats and contact the connecting seats to push the vehicle to move along the vehicle moving guide rail;

[0013] The vehicle moving guide rail includes a front-end track cooperating with the front-end driving device, a tail-end track cooperating with the tail-end driving device, and a middle-section track connecting the two; the front-end driving device and the tail-end driving device are respectively driven by independent power sources, so that the vehicle is pushed forward by the push rods in the front-end track and the tail-end track sections, and power transmission is achieved through physical contact between vehicles in the middle-section track section, forming a closed-loop circulating conveying path composed of an upper-layer running section and a lower-layer return section;

[0014] The loading mechanism and the material sorting mechanism are located above the upper-layer running section of the front-end track. Among them, the loading mechanism includes a hopper and a receiving plate for docking the hopper and the vehicle, and is used to convey the to-be-processed materials onto the vehicle. The material sorting mechanism includes a sweeping component located directly above the moving track of the vehicle and / or a vibrating component located directly below the moving track of the vehicle, and is used to regularize the to-be-processed materials scattered on the strip-shaped bearing bar into the concave cavities of the material supporting units;

[0015] The heating and softening mechanism includes a heating box with a heating cavity. A heating component is provided in the heating box. The upper-layer running section of the middle-section track penetrates through the heating cavity of the heating and softening mechanism to perform heating and softening treatment on the to-be-processed materials on the vehicle passing through the heating cavity;

[0016] The profiling mechanism is arranged on one side of the tail-end track and includes an upper die assembly and a lower die assembly which are arranged oppositely up and down. The upper die assembly is arranged above the carrier of the upper running section of the circulating conveying mechanism, and the lower die assembly is fixedly installed above the lower return section of the circulating conveying mechanism. Moreover, the profiling working parts of the upper die assembly and the lower die assembly are located between two sets of parallel track pairs. When the carrier moves to the profiling station, the upper die assembly presses down to close the die with the lower die assembly to profile and shape the workpiece to be processed on the carrier in the upper running section.

[0017] The blanking mechanism includes a collection bin arranged below the end of the tail-end track for receiving the profiled materials falling from the carrier.

[0018] Further, the strip-shaped bearing bar of the carrier includes a bottom plate and a pressing plate. Through slots corresponding to the number of material supporting units are arranged on both the bottom plate and the pressing plate. The material supporting unit is a thin part integrally formed by thermoplastic plastic through the thermoforming process. A flanging is provided at the upper part of the material supporting unit. The bottom plate and the pressing plate are firmly connected to clamp the flanging of the material supporting unit between the two to realize the fixation of the material supporting unit.

[0019] Further, the feeding mechanism includes a hopper. A long strip-shaped discharging port adapted to the width of the carrier is arranged at the bottom of the hopper. A receiving plate is correspondingly arranged below the discharging port. The receiving plate is inclined towards the side of the moving direction of the carrier. The receiving plate is divided into several relatively independent discharging areas by partitions for uniformly guiding and transferring the workpieces to be processed onto the carrier.

[0020] Further, the material arranging mechanism includes multiple sweeping rollers located directly above the moving track of the carrier. The multiple sweeping rollers are arranged at intervals along the moving direction of the carrier, and the distance from the surface of the carrier gradually decreases along the moving direction of the carrier. Multiple groups of radially extending elastic strip plates are circumferentially and uniformly distributed on the surface of the sweeping roller. The sweeping roller is driven to rotate by a driving device for sweeping the materials piled on the carrier into the concave cavities of the material supporting units.

[0021] Further, the material arranging mechanism further includes a vibrating plate located directly below the moving track of the carrier. A vibrating motor is fixedly installed at the bottom of the vibrating plate. Multiple rows of guiding strip plates are fixedly installed on the upper surface of the vibrating plate. The length direction of the guiding strip plates is parallel to the moving direction of the carrier, and each guiding strip plate is correspondingly arranged in the gap area between adjacent material supporting units.

[0022] Furthermore, the heating and softening mechanism includes a heating box with a heating chamber. Shielded heat-insulating transition cabins are respectively connected to the front and rear ends of the heating box. The vehicle is adapted to enter and exit the heating box through the shielded heat-insulating transition cabins along the middle section of the track. A microwave heating component, an infrared heating component, and a humid-heat heating component are installed on the heating box. Multiple groups of microwave heating components are provided, and the multiple groups of microwave heating components are respectively and evenly arranged on the top wall and / or the bottom plate of the heating box. The infrared heating component includes multiple infrared heating tubes arranged in the heating chamber and evenly distributed along the moving direction of the vehicle. The humid-heat heating component includes a convective heat exchange mechanism and a hot water atomization mechanism. The convective heat exchange mechanism includes more than two forced convection fans. The air inlet end and the air outlet end of the forced convection fan are respectively communicated with the opposite sides of the inner cavity of the heating box, and the air supply directions of two adjacent groups of forced convection fans are opposite. The hot water atomization mechanism includes a heating water tank, a water pump, a conveying pipeline, and an atomizing nozzle. The heating water tank is used for heating and storing hot water. The water inlet end of the water pump is connected to the heating water tank, and the water outlet end is respectively connected to each air supply pipeline connected to the forced convection fan through the conveying pipeline, and the atomizing nozzle is connected to the end of the conveying pipeline. A heat exhaust fan is fixedly installed on the top of the heating box, and the heat exhaust fan is used for exhausting the excess heat in the heating box.

[0023] Furthermore, a temperature sensor and a humidity sensor are arranged in the heating box. The temperature sensor and the humidity sensor are in signal connection with a temperature and humidity control module. The temperature and humidity control module dynamically adjusts the microwave power, the infrared intensity, the atomization amount, the air supply rate of the forced convection fan, and the exhaust rate of the heat exhaust fan according to the data of the temperature sensor and the humidity sensor to adjust the temperature and humidity in the heating box.

[0024] Furthermore, a plurality of forming modules corresponding to the material supporting units one by one are arranged on the pressing working surfaces of the lower die assembly and the upper die assembly. A liftable track corresponding to the upper die assembly and the lower die assembly is arranged in the middle of the upper running section of the tail end track. The liftable track and the upper die assembly and the lower die assembly form a pressing station. A limiting mechanism for moving and limiting the carrier and a position sensor for detecting the arrival of the carrier are arranged at the docking position of the tail end track and the outlet end of the liftable track. One side of the liftable track facing away from the pressing station is fixedly connected with a track support seat. The lower end of the track support seat is connected with a lower lifting cylinder for driving the liftable track to lift. A top column for supporting and limiting the track support seat is arranged below the track support seat. When the carrier moves to the liftable track and contacts the limiting mechanism, the position sensor detects the arrival signal of the carrier and triggers the tail end driving device to stop running. At the same time, the lower lifting cylinder drives the liftable track and the carrier thereon to descend so that the bottom of the material supporting unit contacts the forming module on the lower die assembly. The upper die assembly descends to be clamped with the lower die assembly to complete the pressing and pressure maintaining of the material. After the pressing is completed, the liftable track is driven by the lower lifting cylinder to rise to a high position and dock with the tail end track. The limiting mechanism releases the movement restriction on the carrier. At the same time, the tail end driving device resumes running to push the carrier to continue moving.

[0025] Furthermore, the blanking mechanism includes an auxiliary blanking component and a finished product collecting component. The bottom of the material supporting unit has a through hole smaller than the outer dimension of the supported material. The auxiliary blanking component includes a roller rotating in parallel and synchronously with the transmission shaft of the tail end driving device. A plurality of rows of radially arranged ejector rods are circumferentially and evenly distributed on the surface of the roller. The arrangement spacing and the number of each row of ejector rods correspond to the number of columns and rows of the material supporting units on the strip-shaped bearing bars of the carrier one by one. When the carrier moves to the end of the tail end track, the roller rotates synchronously with the transmission shaft, so that the ejector rods pass through the through holes of the material supporting units to push the materials out of the concave cavities. The finished product collecting component includes a collecting bin located below the end of the tail end track and a transfer component docked with the collecting bin.

[0026] Furthermore, a carrier cleaning mechanism is further included. The carrier cleaning mechanism includes an ultrasonic cleaning tank located in the lower return section of the middle section track. The carrier moves along the lower return section of the middle section track and passes through the ultrasonic cleaning tank.

[0027] The beneficial effects of the present invention are as follows:

[0028] (1) Significantly improve the space utilization rate: By designing a closed-loop circulating conveying path composed of a front-end track, a tail-end track and a middle-section track, the complex loop-shaped conveying layout is avoided, making the production line layout more compact and greatly saving the floor area of the equipment;

[0029] (2) Enhance production continuity: The vehicle and the vehicle moving guide rail adopt an integrated design, eliminating the need for multiple positioning and docking, thus reducing the interruption of the production rhythm. The vehicle is propelled forward by a lever at the front-end track and the tail-end track section, and the power is transmitted through physical contact between vehicles in the middle track section, ensuring the continuity and stability of the entire production process and meeting the requirements of high-speed continuous production.

[0030] (3) Improve heating and softening efficiency and energy consumption control: Compared with the traditional drum conveying and heating tube radiation heating methods, the present invention realizes rapid and uniform heating of the material to be processed through a cleverly designed heating and softening mechanism. At the same time, the phenomenon of surface hardening of the material is avoided, further improving the product quality.

[0031] (4) Achieve full-process automation: The feeding mechanism, material sorting mechanism, molding mechanism, and discharging mechanism of the present invention are all designed for automated operation without manual intervention. This not only improves production efficiency but also ensures product consistency and yield, realizing true full-process automated production and laying a solid foundation for the improvement of production capacity and yield.

When the carrier 800 moves to the liftable track 403 and contacts the limiting mechanism 404, the position sensor detects the arrival signal of the carrier 800 and triggers the end drive device 703 to stop running. At the same time, the lower lifting cylinder 406 drives the liftable track 403 and the carrier 800 thereon to descend so that the bottom of the material supporting unit 804 contacts the forming module 402a on the lower die assembly 402. The upper die assembly 401 descends to close the die with the lower die assembly 402 to complete the press-forming and pressure holding of the material. When the press-forming is completed, the liftable track 403 is driven by the lower lifting cylinder 406 to rise to the high position and dock with the end track 701c. The limiting mechanism 404 releases the movement restriction on the carrier 800. At the same time, the end drive device 703 resumes running to push the carrier 800 to continue moving.

[0075] The blanking mechanism 500 is disposed below the end of the end track 701c and is used for receiving the press-formed material falling from the carrier 800.

[0076] Figure 15 、 Figure 16The structure of a material unloading mechanism 500 of an embodiment of the present invention is shown. The material unloading mechanism 500 includes an auxiliary material unloading component 501 and a finished product collecting component 502. The bottom of the material support unit 804 has a through hole smaller than the outer dimensions of the supported material; the auxiliary material unloading component 501 includes a roller 501a which is parallel to and rotates synchronously with the transmission shaft of the tail end driving device 703, and the surface of the roller 501a is evenly distributed with multiple rows of radially arranged push rods 501b in the circumferential direction, and the arrangement spacing and number of push rods 501b in each row correspond to the number of columns and rows of the material support unit 804 on the strip bearing bar 801 of the carrier 800. When the carrier 800 moves to the end of the tail end track 701c, the roller 501a rotates synchronously with the transmission shaft, so that the push rod 501b passes through the through hole of the material support unit 804 and pushes the material out of the concave cavity. The finished product collection component 502 includes a collection bin located below the end of the tail track 701c and a transfer component docked with the collection bin.

A multi-degree-of-freedom robotic arm equipped with a flexible clamp can be used to push the materials into the concave cavity through a path planning algorithm. A rotating lever mechanism can also be provided to sweep the materials into the target cavity through a periodic swinging action.

[0080] The core function of the heating and softening mechanism is to make the material reach a plastic state through temperature control treatment, which can adopt separate radiation heating, steam heating, hot air convection heating or other known heating technologies;

[0081] The technical essence of the unloading mechanism is to reliably receive and transfer the formed materials. The implementation method can be to transfer the materials by gravity sliding, mechanical pushing, negative pressure adsorption, positive pressure blowing, etc.
