Description

Technical Field

[0001] The present application relates to the field of drying technology, and particularly to an automatic tray loading and drying device for preserved fruits. Background Art

[0002] Preserved fruits are a kind of sweet food made by processing fruits. Preserved fruits are mainly processed and formed through steps such as raw material selection, cleaning, pretreatment, sugar infiltration or sugar boiling, draining, drying, shaping, and packaging.

[0003] When the steps of sugar infiltration or sugar boiling of the preserved fruits are completed, it is necessary for workers to place multiple preserved fruits at intervals on the surface of the filter tray in sequence and put them into the oven for drying treatment, which prolongs the processing cycle of the preserved fruits, thereby increasing the production cost of the preserved fruits. Summary of the Invention

[0004] In order to improve the problem of the processing cycle of preserved fruits, the present application provides an automatic tray loading and drying device for preserved fruits.

[0005] An automatic tray loading and drying device for preserved fruits provided by the present application adopts the following technical solutions: An automatic tray loading and drying device for preserved fruits includes a tray loading device and an oven. The oven has a drying chamber for accommodating the tray loading device. The tray loading device includes a frame body, a plurality of swinging components, a plurality of limiting seats, and a plurality of trays. The plurality of limiting seats are connected to the surface of the frame body at intervals. The limiting seats correspond to the trays one by one. A limiting cavity for the tray to be embedded is formed on the surface of the limiting seat. The surface of the tray is for placing the preserved fruits. The swinging components correspond to the limiting seats one by one and are connected. The swinging component includes a reciprocating lead screw one and a scraper. The reciprocating lead screw one is rotatably connected to the surface of the limiting seat. The scraper is threadedly connected to the outer wall of the reciprocating lead screw one. The scraper slides on the surface of the limiting seat along the axis of the reciprocating lead screw one. The end face of the scraper abuts against the preserved fruits in the tray and pushes the preserved fruits to be distributed dispersedly on the surface of the tray.

[0006] By adopting the above technical solutions, the plurality of trays are embedded in the limiting cavities one by one. The surface of the tray abuts against the inner wall of the limiting cavity to form a limit, realizing the installation of the plurality of trays on the frame body. Workers pour the preserved fruits after the steps of sugar infiltration or sugar boiling into the surfaces of the plurality of trays one by one. The reciprocating lead screw one rotates on the surface of the limiting seat, driving the scraper to slide on the surface of the limiting seat along the axis of the reciprocating lead screw one. The end face of the scraper abuts against the surface of the preserved fruits in the tray and pushes the preserved fruits to be distributed dispersedly on the surface of the tray, realizing the dispersed placement of the preserved fruits on the surface of the tray. Then, the frame body is pushed into the drying chamber, and the oven dries the preserved fruits in the tray. There is no need for workers to place multiple preserved fruits at intervals on the surface of the tray in sequence, shortening the processing cycle of the preserved fruits, thereby reducing the production cost of the preserved fruits.

[0007] Optionally, the dish loading device further includes a power assembly, which includes a power motor, a plurality of power seats, a plurality of inserts, a plurality of power rods, a plurality of transmission wheels, and a plurality of transmission belts used in conjunction with the transmission wheels. The power seats correspond to the limit seats one by one. A sliding cavity for the power seats to slide is provided on the surface of the limit seat. The sliding direction of the power seats is parallel to the axis of the first reciprocating lead screw. The power rods correspond to the power seats one by one and are rotatably connected to the surface of the power seats. The inserts correspond to the power rods one by one and are connected to the rod surface of the power rods facing the first reciprocating lead screw. Embedding grooves for the inserts to be embedded are provided on the rod surface of the first reciprocating lead screw. The motor shaft of the power motor is coaxially connected to the rod surface of one of the power rods. Two of the transmission wheels are in a group. Each group of transmission wheels corresponds to the adjacent power rods one by one and is coaxially connected. The transmission belts correspond to each group of transmission wheels one by one and are tensioned and connected.

[0008] By adopting the above technical solution, when the power seat slides along the inner wall of the sliding cavity towards the direction close to the first reciprocating lead screw, the insert is embedded in the embedding groove, and the outer peripheral surface of the insert abuts against the inner wall of the embedding groove to form a limit. When the power motor operates, the transmission belt is tensioned and connected to the two transmission wheels, driving a plurality of first reciprocating lead screws to rotate around their own axes, realizing the directional start of a plurality of first reciprocating lead screws.

[0009] Optionally, the power assembly further includes a plurality of thermal expansion and contraction blocks. The thermal expansion and contraction blocks correspond to the power seats one by one. One end of the thermal expansion and contraction block is connected to the surface of the power seat, and the other end of the thermal expansion and contraction block is connected to the inner wall of the sliding cavity. When the thermal expansion and contraction block heats up and expands, the thermal expansion and contraction block drives the power seat to slide away from the first reciprocating lead screw, and the insert disengages from the embedding groove.

[0010] By adopting the above technical solution, when the oven heats and dries the dish loading device in the drying cavity, the thermal expansion and contraction block heats up and expands, driving the power seat to slide along the inner wall of the sliding cavity away from the first reciprocating lead screw, and the insert disengages from the embedding groove. There is no need for staff to manually drive the power seat to slide, realizing the directional sliding of the power seat, thereby improving the simplicity of the staff's use of the automatic dish loading and drying device for preserved fruits.

[0011] Optionally, the dish loading device further includes a plurality of vibration components. The vibration components and the limit seats are in one-to-one correspondence and connected. The vibration component includes a cam, a vibration ring, a first elastic member, and a pressing rod. A vibration cavity for the vibration ring to slide is formed in the inner wall of the limit cavity. The sliding direction of the vibration ring is parallel to the height direction of the frame body. The end of the vibration ring faces the bottom of the dish. The cam is in one-to-one correspondence and coaxially connected with the power rod. One end of the pressing rod is connected to the surface of the vibration ring, and the other end of the pressing rod faces the cam surface. One end of the first elastic member in the direction of its elastic force is connected to the inner wall of the vibration cavity, and the other end of the first elastic member in the direction of its elastic force is connected to the bottom of the vibration ring. The first elastic member has an elastic force to drive the vibration ring to slide in the direction close to the limit cavity. When the power seat slides in the direction away from the first reciprocating lead screw, the cam surface abuts against and rolls on the surface of the pressing rod.

[0012] By adopting the above technical solution, when the thermal expansion and contraction block heats up and expands, it drives the power seat to slide along the inner wall of the sliding cavity in the direction away from the first reciprocating lead screw, driving the cam closer to the pressing rod. The cam surface abuts against and rolls on the surface of the pressing rod. The cam has a large end and a small end, driving the vibration ring to slide back and forth on the inner wall of the vibration cavity. The end of the vibration ring abuts against the bottom of the dish, driving the dish to vibrate up and down on the inner wall of the limit cavity, driving the preserved fruits on the surface of the dish to vibrate, making the preserved fruits in the dish heat evenly, thereby accelerating the drying efficiency of the preserved fruits, further shortening the processing cycle of the preserved fruits, and reducing the processing cost of the preserved fruits.

[0013] Optionally, the pressing rod includes a pressing portion, a thermal expansion and contraction portion, and a roller. One end of the thermal expansion and contraction portion is connected to the surface of the vibration ring, and the other end of the thermal expansion and contraction portion is connected to the end face of the pressing portion. The roller is rotatably connected to the end of the pressing portion away from the thermal expansion and contraction portion. When the thermal expansion and contraction portion heats up and expands, the roller surface abuts against and rolls on the cam surface.

[0014] By adopting the above technical solution, when the oven heats the dish loading device in the drying cavity, the thermal expansion and contraction block heats up and expands, driving the power seat to slide in the direction close to the pressing rod. At the same time, the thermal expansion and contraction portion heats up and expands, driving the roller closer to the cam. The roller surface abuts against the cam surface and the roller surface rolls on the cam surface, realizing the directional start of the vibration component.

[0015] Optionally, the dish loading device further includes a plurality of prompting components, which are in one-to-one correspondence and connected with the limit seats. The prompting components include prompting lights, pressure sensors and controllers. The prompting lights are connected to the surface of the limit seats, the pressure sensors are connected to the inner wall of the limit cavities, the pressure sensors are used to detect the weight of the trays, the controllers are connected between the pressure sensors and the prompting lights, the pressure sensors transmit the weight of the trays to the controllers, the controllers compare the weight of the trays with a preset value, and when the weight of the trays is equal to the preset value, the controllers control the prompting lights to be powered on and emit light.

[0016] By adopting the above technical solution, when the staff pour the candied fruits that have completed the sugar seepage or sugar boiling steps onto the tray surface, the pressure sensor detects the weight of the tray in real time. When the controller detects that the weight of the candied fruits on the tray surface is equal to the preset value, the controller controls the prompting light to be powered on and emit light, thereby warning the staff to stop pouring candied fruits onto the tray surface, so that the number of candied fruits on each tray will not be too many or too few, and the accurate control of the number of candied fruits on each tray is realized.

[0017] Optionally, the bottom of the frame body is rotatably connected with universal wheels, and the wheel surfaces of the universal wheels are in rolling contact with the ground.

[0018] By adopting the above technical solution, the wheel surfaces of the universal wheels are in rolling contact with the ground, and rolling friction replaces sliding friction, reducing the wear of the frame body, thereby prolonging the service life of the automatic dish loading and drying device for candied fruits; at the same time, pushing the frame body into the drying cavity, there is no need to lift the frame body into the drying cavity, improving the simplicity of using the automatic dish loading and drying device for candied fruits.

[0019] Optionally, the oven is connected with a limiting component, which includes a limiting plate, a positioning piston, an elastic member II and a positioning plate. The limiting plate is connected to the inner wall of the drying cavity. The surface of the limiting plate facing the frame body is provided with a positioning flow channel for the positioning piston to slide. One end of the elastic member II in the direction of the elastic force is connected to the inner wall of the positioning flow channel, and the other end of the elastic member II in the direction of the elastic force is connected to the surface of the positioning piston. The elastic member II has an elastic force to drive the positioning piston to slide in a direction away from the positioning flow channel, and the end of the positioning piston protrudes from the plate surface of the limiting plate. The inner wall of the drying cavity is provided with a positioning cavity for the positioning plate to slide. The positioning cavity communicates with the positioning flow channel. When the frame body slides along the inner wall of the drying cavity towards the direction close to the limiting plate, the surface of the frame body abuts against the surface of the positioning piston and drives the positioning piston to slide in a direction close to the positioning flow channel. The air in the positioning flow channel enters the positioning cavity and drives the positioning plate to slide in a direction away from the positioning cavity. The end of the positioning plate protruding from the inner wall of the drying cavity abuts against the side wall of the frame body away from the limiting plate, and the plate surfaces of the positioning plate and the limiting plate clamp both sides of the frame body to form a limit.

[0020] By adopting the above technical solution, when the frame body is embedded in the drying cavity, when the frame body slides along the inner wall of the drying cavity towards the direction close to the limiting plate, the surface of the frame body abuts against the end of the positioning piston protruding from the plate surface of the limiting plate and drives the positioning piston to slide towards the direction close to the positioning flow channel. The end of the positioning piston is flush with the plate surface of the limiting plate. The positioning flow channel communicates with the positioning cavity, and the air in the positioning flow channel enters the positioning cavity, increasing the air pressure in the positioning cavity. The air pressure in the positioning cavity drives the positioning plate to slide away from the positioning cavity. The end of the positioning plate protruding from the inner wall of the drying cavity abuts against the side wall of the frame body far from the limiting plate. The plate surface of the positioning plate and the plate surface of the limiting plate clamp both sides of the frame body to form a limit, making it difficult for the frame body to shift in the drying cavity and realizing the limit of the frame body in the drying cavity.

[0021] Optionally, the positioning plate is connected with a clamping assembly. The clamping assembly includes a thermal expansion and contraction strip and a clamping block. A clamping cavity for accommodating the thermal expansion and contraction strip is formed on the plate surface of the positioning plate facing the universal wheel. One end of the thermal expansion and contraction strip is connected to the inner wall of the clamping cavity, and the other end of the thermal expansion and contraction strip is connected to the end face of the clamping block. A clamping groove for the end of the universal wheel to be embedded is formed on the end face of the clamping block far from the thermal expansion and contraction strip. When the end of the positioning plate protrudes from the inner wall of the drying cavity, the notch of the clamping groove faces the end of the universal wheel. The thermal expansion and contraction strip expands when heated, driving the clamping block to slide along the inner wall of the clamping groove towards the direction close to the universal wheel, and the end of the universal wheel is embedded in the clamping groove.

[0022] By adopting the above technical solution, when the notch of the clamping groove faces the end of the universal wheel, the oven heats the frame body in the drying cavity. The thermal expansion and contraction strip expands when heated, driving the clamping block to slide along the inner wall of the clamping groove towards the direction close to the universal wheel. The end of the universal wheel is embedded in the clamping groove, and the end face of the universal wheel abuts against the inner wall of the clamping groove to form a limit, making it difficult for the frame body to shift on the inner wall of the drying cavity, thereby improving the limiting stability of the frame body in the drying cavity; when the heating of the frame body in the drying cavity by the oven is completed, the thermal expansion and contraction strip contracts when cooled, driving the clamping block to slide along the inner wall of the clamping cavity away from the universal wheel, and the end of the universal wheel disengages from the clamping groove, thereby warning the staff to push the frame body out of the drying cavity, making it difficult for the staff to be scalded, and thus improving the simplicity of using the automatic loading and drying device for preserved fruits.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the first reciprocating lead screw and the scraper. The oven dries the preserved fruits in the tray body, eliminating the need for staff to place multiple preserved fruits at intervals on the tray surface in sequence, shortening the processing cycle of the preserved fruits, and thus reducing the production cost of the preserved fruits; 2. The setting of the power motor, power seat, insert block, power rod, transmission wheel and transmission belt. The transmission belt is tensioned and connected to the two transmission wheels, driving multiple first reciprocating lead screws to rotate around their own axes, realizing the directional start of multiple first reciprocating lead screws; 3. The setting of the thermal expansion and contraction block enables the directional sliding of the power seat without manual driving by the staff, thereby improving the simplicity of use of the automatic loading and drying device for preserved fruits by the staff.

The loading device 1 automatically loads the preserved fruits that have been sugared or candied. The oven 2 has a drying chamber 21 that houses the loading device 1, and the oven 2 dries the preserved fruits on the loading device 1, realizing the automatic loading and drying of the preserved fruits. There is no need for workers to place multiple preserved fruits at intervals on the tray surface of the tray 17, shortening the processing cycle of the preserved fruits, and thus reducing the production cost of the preserved fruits.

Universal wheels 3 are rotatably connected to the four corners of the bottom of the frame 11, and the wheel surfaces of the universal wheels 3 are in rolling contact with the ground. Rolling friction replaces sliding friction, reducing the wear of the frame 11, and thus extending the service life of the automatic loading and drying device for preserved fruits.

[0034] Refer to Figure 2 and Figure 4 , Multiple limit seats 16 are fixedly arranged on the surface of the frame 11 at intervals. The arrangement direction of the limit seats 16 is parallel to the height direction of the frame 11. A limit cavity 161 for the tray 17 to be inserted is provided on the top surface of the limit seat 16. The tray surface of the tray 17 is for placing the preserved fruits. Multiple filter holes 171 are provided at intervals on the tray surface of the tray 17. The filter holes 171 penetrate the outer wall of the tray 17, and the filter holes 171 can filter the liquid carried by the preserved fruits; The reminder assemblies 15 are in one-to-one correspondence with and connected to the limit seats 16. The reminder assemblies 15 are used to warn the weight of the preserved fruits in the tray 17. The reminder assemblies 15 include reminder lights 151, pressure sensors 152, and controllers.

The pressure sensors 152 can monitor the weight change of the tray 17 in real time. The controllers are connected between the pressure sensors 152 and the reminder lights 151. A preset value is set in the controllers. The pressure sensors 152 transmit the total mass of the tray 17 and the preserved fruits to the controllers. The controllers compare the total mass with the preset value. When the total mass is equal to the preset value, the controllers drive the reminder lights 151 to be powered on and emit light, warning the workers to stop pouring the preserved fruits onto the tray surface of the tray 17, realizing the precise control of the mass of the preserved fruits on each tray surface of the tray 17.

[0035] Refer to Figure 2 and Figure 3, the swing components 13 correspond to and are connected to the limit seats 16 one by one. The swing components 13 can disperse and distribute the preserved fruits on the surface of the pushing disk body 17. The swing components 13 include a reciprocating screw rod 131 and a scraper 132. The reciprocating screw rod 131 is rotatably connected to the surface of the limit seat 16. The axis of the reciprocating screw rod 131 is parallel to the length direction of the frame body 11. The scraper 132 is threadedly connected to the outer wall of the reciprocating screw rod 131. The scraper 132 slides on the surface of the limit seat 16 along the axis of the reciprocating screw rod 131. The end face of the scraper 132 abuts against the preserved fruits in the disk body 17 and pushes the preserved fruits to be dispersed and distributed on the surface of the disk body 17. It is not necessary for the staff to place multiple preserved fruits at intervals on the surface of the disk body 17 in sequence, realizing the automatic loading operation of the preserved fruits on the surface of the disk body 17.

[0036] Refer to Figure 3 and Figure 4 , the power component 12 can drive multiple reciprocating screw rods 131 to rotate around their own axes.

The material of the thermal expansion and contraction blocks 127 can be nylon or memory alloy. In the embodiment of the present application, the material of the thermal expansion and contraction blocks 127 is memory alloy, which has a good coefficient of thermal expansion. The power seats 122 correspond to the limit seats 16 one by one. A sliding cavity 162 for the power seats 122 to slide is provided on the surface of the limit seat 16. The sliding direction of the power seats 122 is parallel to the axis of the reciprocating screw rod 131. The power rods 124 correspond to the power seats 122 one by one and are rotatably connected to the surface of the power seats 122. The axis of the power rods 124 coincides with the axis of the reciprocating screw rod 131. The inserts 123 correspond to the power rods 124 one by one and are fixed on the rod surface of the power rods 124 facing the reciprocating screw rod 131. An insertion groove 1311 for the inserts 123 to be inserted is provided on the rod surface of the reciprocating screw rod 131. The thermal expansion and contraction blocks 127 correspond to the power seats 122 one by one. One end of the thermal expansion and contraction blocks 127 is fixed to the inner wall of the sliding cavity 162. The thermal expansion and contraction blocks 127 are located on the side of the power seats 122 close to the reciprocating screw rod 131. The inserts 123 are inserted into the insertion grooves 1311, and the outer peripheral surface of the inserts 123 abuts against the inner wall of the insertion grooves 1311 to form a limit, realizing the connection between the power rods 124 and the reciprocating screw rods 131.

[0037] Refer to Figure 3 and Figure 4, the power motor 121 is fixed on the surface of one of the power seats 122 by bolts. The end of the motor shaft of the power motor 121 penetrates through the outer wall of the power seat 122 and is coaxially fixed to the end of the power rod 124 away from the reciprocating lead screw 131. Two transmission wheels 125 are in a group. Each group of transmission wheels 125 corresponds to and is coaxially fixed to two adjacent power rods 124 one by one. The transmission belt 126 corresponds to each group of transmission wheels 125 one by one and is tensioned and connected. When the thermal expansion and contraction block 127 heats up and expands, it drives the power seat 122 to slide along the inner wall of the sliding cavity 162 in the direction away from the reciprocating lead screw 131, and the insert block 123 disengages from the insert groove 1311, realizing the directional fixation between the power rod 124 and the reciprocating lead screw 131.

[0038] Referring to Figure 3 and Figure 4 , the vibration assembly 14 corresponds to and is connected to the limit seat 16. The vibration assembly 14 drives the disk body 17 to slide up and down in the limit cavity 161. The vibration assembly 14 includes a cam 141, a vibration ring 142, a first elastic member 143, and a pressing rod 144. The first elastic member 143 can be a compression spring or a tension spring.

A vibration cavity 163 for the vibration ring 142 to slide is provided on the bottom wall of the limit cavity 161. The sliding direction of the vibration ring 142 is parallel to the height direction of the frame body 11. The first elastic member 143 has an elastic force to drive the vibration ring 142 to slide in the direction away from the vibration cavity 163, and there is a tendency for the end of the vibration ring 142 protruding from the bottom wall of the limit cavity 161 to abut against the bottom of the disk body 17.

[0039] Referring to Figure 3 and Figure 4, the cam 141 corresponds to and is coaxially fixed to the power rod 124 one by one. The pressing rod 144 includes a pressing portion 1441, a thermal expansion and contraction portion 1442, and a roller 1443. The material of the thermal expansion and contraction portion 1442 can be shape memory alloy or nylon.

One end of the thermal expansion and contraction portion 1442 is fixed on the surface of the vibration ring 142, and the other end of the thermal expansion and contraction portion 1442 is fixed on the end face of the pressing portion 1441. The roller 1443 is rotatably connected to the end face of the pressing portion 1441 away from the thermal expansion and contraction portion 1442. When the thermal expansion and contraction portion 1442 and the thermal expansion and contraction block 127 are heated and expanded, the power seat 122 slides along the inner wall of the sliding cavity 162 in the direction close to the roller 1443. At the same time, the thermal expansion and contraction portion 1442 drives the pressing portion 1441 to approach the cam 141. The wheel surface of the roller 1443 abuts against the wheel surface of the cam 141 and the wheel surface of the roller 1443 rolls in contact with the wheel surface of the cam 141. The cam 141 has a large end and a small end, driving the vibration ring 142 to slide back and forth on the inner wall of the vibration cavity 163. The end of the vibration ring 142 protruding from the inner wall of the limiting cavity 161 abuts against the bottom of the disk body 17, driving the disk body 17 to slide back and forth on the inner wall of the limiting cavity 161, driving the dried fruits in the disk body 17 to vibrate and swing, so that the dried fruits on the disk surface of the disk body 17 are evenly heated, improving the processing efficiency of the dried fruits, shortening the processing cycle of the dried fruits, and thus reducing the processing cost of the dried fruits.

[0040] Refer to Figure 1 and Figure 5 , the oven 2 is rotatably connected with a cabinet door 4 covering the drying cavity 21. The oven 2 is connected with a limiting component 5. The limiting component 5 can limit the frame body 11 in the drying cavity 21. The limiting component 5 includes a limiting plate 51, a positioning piston 52, an elastic member two 53, and a positioning plate 54. The material of the positioning piston 52 can be rubber or silica gel. In the embodiment of the present application, the material of the positioning piston 52 is rubber, which has a certain deformation ability. The elastic member two 53 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member two 53 is a compression spring, which has a certain deformation ability. One end of the limiting plate 51 is fixed on the inner wall of the drying cavity 21 away from the cabinet door 4. A positioning flow channel 511 for the positioning piston 52 to slide is opened on the surface of the limiting plate 51 facing the cabinet door 4. The sliding direction of the positioning piston 52 is parallel to the width direction of the oven 2. One end of the elastic member two 53 in the direction of the elastic force is fixed on the inner wall of the positioning flow channel 511, and the other end of the elastic member two 53 in the direction of the elastic force is fixed on the plate surface of the limiting plate 51. The elastic member two 53 has an elastic force to drive the positioning piston 52 to slide in the direction away from the positioning flow channel 511, and the end of the positioning piston 52 protrudes from the plate surface of the limiting plate 51.

[0043] The implementation principle of an automatic fruit preserve loading and drying device in an embodiment of this application is as follows: Workers pour the sugared or sugar-boiled fruit preserves onto the surface of the tray 17 in sequence. The pressure sensor 152 transmits the total mass of the tray 17 and the fruit preserves to the controller. The controller compares the total mass with a preset value. When the total mass is equal to the preset value, the controller drives the indicator light 151 to be energized and emit light, warning the workers to stop pouring the fruit preserves onto the surface of the tray 17, thus achieving precise control over the mass of the fruit preserves on the surface of each tray 17. The inlay blocks 123 are respectively embedded into the inlay grooves 1311, realizing the installation of the power rod 124 and the first reciprocating lead screw 131. The power motor 121 operates, driving multiple first reciprocating lead screws 131 to rotate around their own axes, driving the scraper 132 to slide on the surface of the limit seat 16 along the axis of the first reciprocating lead screw 131. The end face of the scraper 132 abuts against the fruit preserves in the tray 17 and pushes the fruit preserves to be distributed dispersedly on the surface of the tray 17. There is no need for workers to place multiple fruit preserves at intervals on the surface of the tray 17 in sequence, realizing the automatic fruit preserve loading action on the surface of the tray 17. There is no need for workers to place multiple fruit preserves at intervals on the surface of the tray 17 in sequence, shortening the processing cycle of the fruit preserves, and thus reducing the production cost of the fruit preserves.
