Description

Technical Field

[0001] This invention belongs to the field of fruit and vegetable food processing technology, and in particular relates to a fruit and vegetable food preservation device based on a composite polysaccharide film. Background Technology

[0002] To prevent damage, stains, and rapid loss of freshness during the transportation and storage of fruits and vegetables, protective layers such as plastic bags, paper, or wax are wrapped around them during production and processing. However, these protective layers are neither environmentally friendly nor safe. With increasing environmental awareness, people are gradually replacing traditional protective layers with composite polysaccharide films. As a new type of packaging material, composite polysaccharide films have advantages such as being green and environmentally friendly, biodegradable, non-toxic and harmless, and able to improve the quality of food. They also have nutritional value.

[0003] However, the existing applications of composite polysaccharide films in fruit and vegetable food production and processing have the following shortcomings:

[0004] 1. In the existing fruit and vegetable food production and processing, after washing the fruits and vegetables, workers need to manually wrap the outside of the fruits and vegetables with a composite polysaccharide film, which is a troublesome operation and has low production efficiency.

[0005] 2. In the existing production and processing of fruits and vegetables, due to the material of the composite polysaccharide film itself, if there is a lot of moisture on the fruits and vegetables, it will seriously affect the quality of the composite polysaccharide film. Therefore, people will wipe the fruits and vegetables to remove water, but manual wiping is inefficient, while drying can easily cause the fruits and vegetables to oxidize too quickly.

[0006] 3. In the existing fruit and vegetable food production and processing, there is a problem that the surface water stains of fruits and vegetables are not completely removed. The residual water stains reduce the freshness time of fruits and vegetables and affect their storage.

[0007] Therefore, it is necessary to improve existing technologies to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a fruit and vegetable food preservation device based on a composite polysaccharide film. This preservation device can quickly and efficiently wrap the composite polysaccharide film around the outside of fruits and vegetables, and the water removal and wiping of fruits and vegetables is convenient and thorough, effectively maintaining the freshness of fruits and vegetables. It solves the problems of low wrapping efficiency of composite polysaccharide film, incomplete wiping of moisture on the surface of fruits and vegetables, troublesome water wiping, and water wiping easily leading to a decrease in the freshness of fruits and vegetables in the existing fruit and vegetable food production, processing and preservation process.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] The present invention is a fruit and vegetable food preservation and processing device based on a composite polysaccharide film, comprising a first inclined plate and a second inclined plate disposed at the lower end of the first inclined plate, wherein both the first and second inclined plates are fixedly connected to a base plate by support columns, and a U-shaped frame plate, a dispensing mechanism and a heat sealing mechanism are sequentially arranged above the second inclined plate from the upper inclined end to the lower inclined end, wherein the bottom surfaces of both ends of the U-shaped frame plate are fixedly connected to the second inclined plate.

[0011] The dispensing mechanism includes an L-shaped plate, a partition plate, and a first heating strip. Multiple partition plates are arranged in a horizontal array on one side of the opening of the L-shaped plate. The upper ends of the multiple partition plates are fixedly connected to the same crossbar, and the lower ends of the multiple partition plates are fixedly connected to the same gathering column. The bottom surface of the L-shaped plate is also fixedly connected to the gathering column.

[0012] The inner wall of the L-shaped plate is evenly provided with first air intake holes, and the side of the partition plate near the L-shaped plate is evenly provided with second air intake holes. The second air intake holes are connected to the first flow cavity in the partition plate. The first flow cavity is connected to the second flow cavity in the L-shaped plate through a first flexible tube. The second flow cavity is connected to the first air intake holes.

[0013] A second flexible tube communicating with the second flow cavity is fixedly connected to the top surface of the L-shaped plate. The other end of the second flexible tube is connected to the air inlet of the air pump through an air supply pipe, and the air pump is fixedly connected to the top surface of the bottom plate.

[0014] The top plate of the L-shaped plate is provided with a central through groove, and a central block is fitted in the central through groove with a gap. The central block is fixedly connected to the top surface of the crossbar, and a first electric push rod is fixedly connected to the side of the central block near the closed end of the L-shaped plate. The fixed section of the first electric push rod is fixedly connected to the vertical plate of the L-shaped plate.

[0015] Two converging columns are provided with a first through groove along the horizontal direction. A first heating strip is fitted in the first through groove with a gap. A connecting plate is fixedly connected to the middle of the outer side of the first heating strip. A second electric push rod is fixedly connected to one side of the upper end of the connecting plate. The two second electric push rods are respectively fixedly connected to the central block and the L-shaped plate.

[0016] The heat sealing mechanism includes a second heating strip, a first connecting rod, and a second connecting rod. Multiple second heating strips are arranged in a one-to-one correspondence with multiple partition plates, and the top of each end of the second heating strip is fixedly connected to the first connecting rod. Both first connecting rods are fixedly connected to the outer surface of the L-shaped plate through the second connecting rod.

[0017] A second through groove is provided on the second inclined plate between the dispensing mechanism and the heat sealing mechanism. A vertically extendable baffle is provided in the second through groove. Dividing strips are evenly distributed on the top surface of the second inclined plate below the U-shaped frame plate. Meanwhile, cutting blades with cutting ends close to the baffles are evenly distributed on the top surface of the second inclined plate on the side away from the U-shaped frame plate.

[0018] Multiple separators, multiple cutters, and multiple second heating bars are arranged in a one-to-one correspondence.

[0019] Through the aforementioned improvements, this invention allows washed fruits and vegetables to fall onto a second inclined plate. After being separated by partition strips, they are kept at a certain distance and blocked on one side of the strips. At this time, the packaging mechanism, carrying the composite polysaccharide film adsorbed on its inner wall, covers the fruits and vegetables. Then, the first electric push rod retracts, causing the crossbar to move multiple partition plates towards the L-shaped plate. With this action, two closing columns lift the fruits and vegetables from the bottom. Then, two second electric push rods retract simultaneously, causing two first heating strips to come closer together and overlap, heat-sealing the composite polysaccharide film under the fruits and vegetables. After completing the above steps, the heat-sealing mechanism is moved above the fruits and vegetables. As the heat-sealing mechanism moves downward, multiple second heating strips adhere to the composite polysaccharide film between adjacent fruits and vegetables for further heat-sealing. After this heat-sealing is completed, the heat-sealing mechanism moves upward, the partition strips move downward, and the heat-sealed fruits and vegetables slide to the cutting position and are cut along the adhesive position, realizing the subsequent transportation of the fruits and vegetables. This setting can achieve rapid coating of the composite polysaccharide film on fruits and vegetables.

[0020] Furthermore, clamping plates are provided at both ends of both sides of the U-shaped frame plate, and a telescopic column is fixedly connected to one side of the clamping plate. The other end of the telescopic column slides through the fixing ear on the end face of the U-shaped frame plate and is fixedly connected to the first limiting plate. A first reset spring is slidably sleeved on the telescopic column at the position between the fixing ear and the first limiting plate.

[0021] Furthermore, a third electric push rod is fixedly connected to both ends of the L-shaped plate, a connecting block is fixedly sleeved on the fixed section of the third electric push rod, a fourth electric push rod is fixedly connected to one side of the connecting block, and the fourth electric push rod is fixedly connected to the side of the second inclined plate.

[0022] Furthermore, an iron bar is fixedly connected to the bottom surface of the stop bar, and a first guide rod is fixedly connected to the bottom surface of the stop bar on both sides of the iron bar. The other end of the first guide rod slides through the limiting rod and is fixedly connected to the second limiting plate. The limiting rod is fixedly connected to the bottom surface of the second inclined plate, and an electromagnetic plate is fixedly connected to the top surface of the limiting rod at the position between the two first guide rods. A second reset spring is slidably sleeved on the first guide rod at the position between the stop bar and the limiting rod.

[0023] As a further improvement of the present invention, a conveyor belt is fitted onto the upper end of the first inclined plate, and a third through groove is provided on the first inclined plate below the conveyor belt, and a telescopic plate perpendicular to the conveyor belt is slidably fitted into the third through groove.

[0024] The telescopic plate is provided with a fourth through slot with open ends, and a rectangular rod is horizontally arranged in the fourth through slot. The two ends of the rectangular rod are fixedly connected to the inner end wall of the third through slot. A second guide rod is slidably sleeved on the rectangular rod, and both ends of the second guide rod are fixedly connected to the inner side wall of the fourth through slot. A fifth electric push rod is also fixedly connected to the middle of one side of the telescopic plate, and the fifth electric push rod is fixedly connected to the bottom surface of the first inclined plate.

[0025] A pressure plate is also arranged parallel to the front side of the conveyor belt, and a water-absorbing sponge is provided on the side of the pressure plate near the conveyor belt. A cylinder is fixedly connected to the upper middle part of the pressure plate, and the fixed section of the cylinder is fixedly sleeved on the first inclined plate.

[0026] Through the above improvements, the present invention allows the washed fruits and vegetables to fall into the feeding box and be carefully arranged on the telescopic plate by the conveyor belt. While the first motor continues to drive the conveyor belt to move, the fifth electric push rod drives the pressure plate to move down, and the water-absorbing sponge adheres to the fruits and vegetables. With the help of the conveyor belt driving the rotation of the fruits and vegetables, water stains on the fruits and vegetables can be wiped off, improving wiping efficiency and avoiding the loss of freshness caused by drying.

[0027] Furthermore, rollers are slidably sleeved on the inner sides of both ends of the conveyor belt, and the rollers are fixedly sleeved on the first rotating shaft, and both ends of the first rotating shaft are rotatably connected to the side wall of the first inclined plate through rolling bearings.

[0028] One end of one of the first rotating shafts is also fitted into the output end of the first motor, and the first motor is fixedly connected to the first inclined plate;

[0029] Ribs are evenly distributed on the outer wall of the conveyor belt along the conveying direction.

[0030] Furthermore, a third guide rod is fixedly connected to the upper end of the pressure plate on both sides of the cylinder, and one end of the third guide rod slides through the first inclined plate and is fixedly connected to the third limiting plate.

[0031] Furthermore, a feed box is fixedly connected to the first inclined plate at one end of the conveyor belt, and an inclined block is provided on the inner side wall of the feed box to guide the goods onto the conveyor belt.

[0032] As another further improvement of the present invention, an adjustment plate is provided between the first inclined plate and the second inclined plate, and a second rotating shaft is fixedly sleeved on one end of the adjustment plate, and both ends of the second rotating shaft are rotatably connected to the second inclined plate through rolling bearings.

[0033] The first inclined plate and the second inclined plate are respectively provided with a first roller and a second roller at their closer ends, and a nozzle fixedly connected to the base plate is provided below the position between the first roller and the second roller. The nozzle is connected to the air outlet end of the air pump through an air outlet pipe. An air inlet pipe is also connected to the air supply pipe. A first solenoid valve is fixedly installed on the air supply pipe near the second flexible hose, and a second solenoid valve is fixedly installed on the air inlet pipe.

[0034] The first roller is located below the first inclined plate and is fixedly sleeved on the third rotating shaft. Both ends of the third rotating shaft are rotatably connected to the first inclined plate through rolling bearings. One end of the third rotating shaft is fitted into the output end of the second motor, and the second motor is fixedly connected to the first inclined plate.

[0035] The second roller is fixedly sleeved on the fourth rotating shaft, and both ends of the fourth rotating shaft are rotatably connected to the second inclined plate through rolling bearings.

[0036] Through the above improvements, the fruits and vegetables, after initial wiping, fall between the first and second rollers under the guidance of the first inclined plate. Under the action of the second motor driving the first roller to rotate, the fruits and vegetables rotate on their own while maintaining a limited position between the first and second rollers. At this time, the high-speed air sprayed from the nozzle can further remove water from the surface of the fruits and vegetables, thereby reducing the residual moisture on the surface of the fruits and vegetables.

[0037] Furthermore, a hydraulic cylinder is provided below the adjusting plate, and rotating plates are fixedly connected to both ends of the hydraulic cylinder. One rotating plate is fixedly connected to the bottom surface of the second inclined plate through a first rotating frame, while the other rotating plate is rotatably connected to the rotating column at the lower end of the adjusting rod. The upper end of the adjusting rod is rotatably connected to the bottom surface of the adjusting plate through a second rotating frame.

[0038] The present invention has the following beneficial effects:

[0039] The combined packaging and heat-sealing mechanisms of this invention enable automatic wrapping of composite polysaccharide films on the surface of fruits and vegetables. The wrapped composite polysaccharide films can then be automatically heat-sealed and automatically cut, thereby achieving automated wrapping of composite polysaccharide films on the surface of fruits and vegetables and greatly improving wrapping efficiency.

[0040] The present invention enables the conveyor belt to drive the fruits and vegetables to rotate automatically, while the water-absorbing sponge adheres to the fruits and vegetables, which can automatically wipe the moisture on the surface of the fruits and vegetables, greatly improving the efficiency of wiping moisture and avoiding the shortcomings of drying that reduce the freshness of fruits and vegetables.

[0041] The rotation of the first roller in this invention can achieve the limited flipping of fruits and vegetables between the first roller and the second roller. During the flipping process, the high-speed air ejected from the nozzle can further remove water from the surface of the fruits and vegetables, thereby reducing the residual moisture on the surface of the fruits and vegetables and increasing the duration of freshness.

Detailed Implementation

[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0058] Please see Figure 1-3As shown in the figure, the present invention is a fruit and vegetable food preservation and processing device based on a composite polysaccharide film, including a first inclined plate 1 and a second inclined plate 6 disposed at the lower inclined end of the first inclined plate 1. Both the first inclined plate 1 and the second inclined plate 6 are fixedly connected to the base plate 7 by support columns. Above the second inclined plate 6, from the upper inclined end to the lower inclined end, a U-shaped frame plate 601, a dispensing mechanism 4 and a heat sealing mechanism 5 are arranged in sequence. The bottom surfaces of both ends of the U-shaped frame plate 601 are fixedly connected to the second inclined plate 6. As can be seen from the figure, the above components constitute the basic structure of the device. The first inclined plate 1 and the second inclined plate 6 are inclined so that the fruits and vegetables can move under their own gravity. In actual use, the device is also equipped with a PLC controller for controlling the various electrical components in the device.

[0059] Please see Figure 1 and 10 As shown in -12, the dispensing mechanism 4 includes an L-shaped plate 401, a partition plate 402, and a first heating strip 403. Multiple partition plates 402 are arranged in a horizontal array on one side of the opening of the L-shaped plate 401. The upper ends of the multiple partition plates 402 are fixedly connected to the same crossbar 4022. The partition plates 402 can separate fruits and vegetables, which facilitates subsequent cutting and transportation. At the same time, the lower ends of the multiple partition plates 402 are fixedly connected to the same gathering column 405. The bottom surface of the L-shaped plate 401 is also fixedly connected to the gathering column 405.

[0060] Specifically, a central through groove 4012 is provided in the middle of the top plate of the L-shaped plate 401, and a central block 4041 is fitted in the central through groove 4012 with a gap. This arrangement can limit and guide the movement of the central block 4041. The central block 4041 is fixedly connected to the top surface of the crossbar 4022, and a first electric push rod 404 is fixedly connected to the side of the central block 4041 near the closed end of the L-shaped plate 401. The fixed section of the first electric push rod 404 is fixedly connected to the vertical plate of the L-shaped plate 401.

[0061] When in use, the above-mentioned configuration allows the medium block 4041 to move back and forth in the medium through groove 4012 by extending and retracting the first electric push rod 404. Under the action of this movement, the medium block 4041 can drive the crossbar 4022 to move, thereby enabling the two closing columns 405 to lift the fruits and vegetables from below when they are close to each other.

[0062] The inner wall of the L-shaped plate 401 is provided with first air intake holes 4016 evenly distributed, and the partition plate 402 is provided with second air intake holes 4021 evenly distributed on the side surface of the partition plate 402 near the L-shaped plate 401. The second air intake holes 4021 are connected to the first flow cavity in the partition plate 402. At the same time, the first flow cavity is connected to the second flow cavity in the L-shaped plate 401 through the first flexible tube. The second flow cavity is connected to the first air intake holes 4016.

[0063] A second flexible tube 4011 communicating with the second flow cavity is fixedly connected to the top surface of the L-shaped plate 401. The other end of the second flexible tube 4011 is connected to the air inlet of the air pump 9 through the air supply pipe 901, and the air pump 9 is fixedly connected to the top surface of the base plate 7.

[0064] When in use, the above-mentioned setup allows for air extraction from the air supply pipe 901 via the operation of the air pump 9, which in turn allows the second hose 4011 to extract air from the first and second flow chambers. Finally, the first suction port 4016 and the second suction port 4021 are in a negative pressure state, which facilitates the adsorption and fixation of the composite polysaccharide film.

[0065] Please see Figure 10-12 As shown, a first through groove 4051 is provided on the two converging columns 405 along the horizontal direction. A first heating strip 403 is fitted in the first through groove 4051 with a gap. A connecting plate 4031 is fixedly connected to the middle of the outer side of the first heating strip 403. A second electric push rod 4032 is fixedly connected to one side of the upper end of the connecting plate 4031. The two second electric push rods 4032 are respectively fixedly connected to the medium block 4041 and the L-shaped plate 401.

[0066] The heat sealing mechanism 5 includes a second heating strip 501, a first connecting rod 502 and a second connecting rod 503. Multiple second heating strips 501 are arranged in a one-to-one correspondence with multiple partition plates 402, and the top of each end of the second heating strip 501 is fixedly connected to the first connecting rod 502. Both first connecting rods 502 are fixedly connected to the outer surface of the L-shaped plate 401 through the second connecting rod 503.

[0067] When the above-mentioned setup is in use, after the two closing columns 405 lift the fruits and vegetables from the bottom, the second electric push rod 4032 retracts, so that the first heating strip 403 is fed into the first through groove 4051, and the two first heating strips 403 come closer to each other, thereby achieving mutual heat sealing of the composite polysaccharide film under the fruits and vegetables.

[0068] After the heat sealing is completed, the first electric push rod 404 extends to reset the partition plate 402. Under the action of resetting, the fruits and vegetables containing the preliminary composite polysaccharide film fall onto the first inclined plate 1. Then the heat sealing mechanism 5 moves above the fruits and vegetables and then moves down. The second heating strip 501 heat seals the composite polysaccharide film between adjacent fruits and vegetables.

[0069] Please see Figure 3 , 8 As shown in Figure 9, a second through groove 602 is provided on the second inclined plate 6 between the dispensing mechanism 4 and the heat sealing mechanism 5. A vertically extendable baffle 603 is provided in the second through groove 602. The baffle 603 can block and limit the movement of fruits and vegetables.

[0070] Specifically, an iron strip 6031 is fixedly connected to the bottom surface of the stop bar 603, and a first guide rod 6034 is fixedly connected to the bottom surface of the stop bar 603 on both sides of the iron strip 6031. The movement of the first guide rod 6034 can limit and guide the up and down movement of the stop bar 603. The other end of the first guide rod 6034 slides through the limiting rod 6035 and is fixedly connected to the second limiting plate 6033. The setting of the second limiting plate 6033 can limit one end of the first guide rod 6034 and prevent the first guide rod 6034 from detaching from the limiting rod 6035. The limiting rod 6035 is fixedly connected to the bottom surface of the second inclined plate 6, and an electromagnetic plate 6036 is fixedly connected to the top surface of the limiting rod 6035 between the two first guide rods 6034. A second return spring 6032 is slidably sleeved on the first guide rod 6034 between the stop bar 603 and the limiting rod 6035. The setting of the second return spring 6032 can realize the reset of the stop bar 603.

[0071] When the electromagnetic plate 6036 is energized, it can generate a corresponding magnetism to attract the iron strip 6031, and the baffle 603 is stored in the second through groove 602, thus losing its obstruction of fruits and vegetables. When the electromagnetic plate 6036 is de-energized, it loses its attraction to the iron strip 6031. Under the reset action of the second reset spring 6032, the baffle 603 extends out of the second through groove 602 to block the fruits and vegetables.

[0072] Dividing strips 605 are evenly distributed on the top surface of the second inclined plate 6 below the U-shaped shelf 601. The dividing strips 605 can achieve the initial separation of fruits and vegetables. At the same time, cutters 604 with cutting ends close to the side of the side of the second inclined plate 6 away from the U-shaped shelf 601 are evenly distributed on the top surface of the baffle 603. The cutters 604 can cut the heat-sealed composite polysaccharide film.

[0073] Multiple separators 605, multiple cutters 604, and multiple second heating bars 501 are arranged in a one-to-one correspondence.

[0074] Please see Figure 8 and 9 As shown, clamping plates 6011 are provided at both ends of both sides of the U-shaped frame plate 601. A telescopic column 6012 is fixedly connected to one side of the clamping plate 6011. The other end of the telescopic column 6012 slides through the fixing ear 6015 on the end face of the U-shaped frame plate 601 and is fixedly connected to the first limiting plate 6014. A first return spring 6013 is slidably sleeved on the telescopic column 6012 at the position between the fixing ear 6015 and the first limiting plate 6014. The setting of the first limiting plate 6014 can realize the limiting of the telescopic column 6012 on the fixing ear 6015. The first return spring 6013 can realize the automatic adjustment of the position of the clamping plate 6011.

[0075] A third electric push rod 4013 is fixedly connected to both ends of the L-shaped plate 401. A connecting block 4014 is fixedly sleeved on the fixed section of the third electric push rod 4013. A fourth electric push rod 4015 is fixedly connected to one side of the connecting block 4014, and the fourth electric push rod 4015 is fixedly connected to the side of the second inclined plate 6.

[0076] In use, the composite polysaccharide film is stacked on the top surface of the U-shaped frame plate 601, and the clamping plate 6011 clamps and fixes it from the outside. Under the action of the third electric push rod 4013 and the fourth electric push rod 4015, the dispensing mechanism 4 moves above the U-shaped frame plate 601 and covers the composite polysaccharide film to adsorb the film, realizing automated feeding of the composite polysaccharide film. After the composite polysaccharide film is adsorbed and lifted, the clamping plate 6011 automatically re-clamps under the reset action of the first return spring 6013. Of course, the cooperation of the third electric push rod 4013 and the fourth electric push rod 4015 can also realize the movement and switching between the dispensing mechanism 4 and the heat sealing mechanism 5.

[0077] Please see Figure 1-7 As shown, a conveyor belt 104 is fitted onto the upper end of the first inclined plate 1, and a third through groove 105 is provided on the first inclined plate 1 below the conveyor belt 104. A telescopic plate 102 perpendicular to the conveyor belt 104 is slidably fitted into the third through groove 105.
