Description

Technical Field

[0001] The invention relates to the technical field of fruit packaging, in particular to a fruit packaging device capable of pre-cleaning. Background Art

[0002] Most of the existing fruit packaging equipment cannot pre-clean the fruits, and the stains attached to the outside of many fruits, such as grapefruit and cherry, will affect the freshness of the fruits, and will also cause a bad impression to subsequent consumers.

[0003] Chinese patent CN114435658B discloses a pre-cleanable fruit packaging device, comprising a frame, a gantry, an L-shaped plate, a first electric push rod, a first elastic plate, a surface cleaning system, a branch cutting system and a film covering system; the gantry is fixedly connected to the rear side of the upper surface of the frame; the L-shaped plate is connected to the upper surface of the gantry; the L-shaped plate is fixedly connected to the first electric push rod; the telescopic part of the first electric push rod is fixedly connected to the first elastic plate; the front part of the gantry is connected to the surface cleaning system for cleaning dirt on the surface of pomelo; the lower surface of the upper part of the gantry is connected to the branch cutting system for shortening the branches at the head of the pomelo; the upper surface of the gantry is connected to the film covering system for covering the surface of the pomelo, and the film covering system is located below the gantry.

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1 and Figure 3-Figure 6 A fruit packaging device capable of pre-cleaning comprises a shell 1, a discharge port 11 is arranged at the bottom of the shell 1; a cleaning unit 2 is arranged in the shell 1, the cleaning unit 2 comprises a cleaning barrel 21 which is horizontally rotatably arranged in the shell 1, an annular cleaning chamber is arranged in the cleaning barrel 21 along the axial direction of the cleaning barrel 21, a plurality of partition plates 22 are arranged in the annular cleaning chamber, the plurality of partition plates 22 are evenly distributed around the axis of the annular cleaning chamber, the partition plates 22 divide the annular cleaning chamber into a plurality of cleaning tanks of equal volume, the cleaning tanks are used to store cherries, one end of the cleaning tank away from the annular cleaning chamber is an opening, a cleaning shell 23 is sleeved on the outside of the cleaning barrel 21, a discharge port 232 and a feed port 231 are respectively arranged at the upper part of the cleaning shell 23, cleaning liquid is injected into the cleaning shell 23, a push-out unit 24 is arranged at the bottom of the cleaning tank, when the cleaning tank is driven by the cleaning barrel 21 to rotate to the position of the discharge port 232, the push-out unit 24 pushes the cherries in the cleaning tank out of the discharge port 232, and the volume of the cleaning tank is reduced.

[0036] Since the hardness of the skin of different fruits is different, different cleaning methods are used when cleaning different fruits. When cleaning cherries, since the hardness of the skin of cherries is relatively low, if the cherries are directly cleaned with a cleaning brush, the surface of the cherries will be damaged. The existing method for cleaning cherries is the soaking cleaning method, that is, soaking the cherries in salt water or alkaline water for 8-15 minutes. If the cherries need to be packaged in batches, they need to be washed in batches. When washing the batch cherries, the cherries in the salt water are partially suspended and partially sunk to the bottom. Therefore, when soaking the same batch of cherries, the washing barrel 21 used for soaking the cherries is in an occupied state, and after the soaking is completed, all the cherries in the washing barrel 21 need to be salvaged, which seriously affects the subsequent packaging efficiency.

[0037] In order to avoid the above situation, the cleaning unit 2 is redesigned so that the cleaning unit 2 can automatically remove the cherries synchronously when soaking the cherries. The specific working steps are as follows: the cleaning barrel 21 is horizontally arranged in the outer shell 1, and the cleaning shell 23 is provided on the outside of the cleaning barrel 21. The upper part of the cleaning shell 23 is respectively provided with a feed port 231 and a discharge port 232. The partition plate 22 evenly divides the annular cleaning chamber in the cleaning barrel 21 into a plurality of cleaning slots. As the cleaning barrel 21 rotates, when one of the cleaning slots in the cleaning barrel 21 rotates to the feed port 231 of the cleaning shell 23, a cleaning slot adjacent to the cleaning slot is located at the discharge port 232. When cleaning, the cherries are put into the cleaning barrel 21 from the feed port 231 of the cleaning shell 23, and the cherries enter the cleaning slot below the feed port 231. In the process of putting the cherries into the cleaning slot, the cleaning barrel 21 is continuously in a rotating state. The time for the cleaning barrel 21 to rotate one circle is 8-15 minutes, and the amount of cherries put into the cleaning slot each time is constant. The cleaning shell 23 is filled with cleaning liquid, and the cleaning liquid is preferably salt water, so as to ensure that the cleaned cherries can be eaten directly after being fished out and packaged. After the cherries are fed into the feed port 231, the continuously rotating cleaning barrel 21 drives the cleaning tank to gradually rotate. When the opening of the cleaning tank is blocked by the cleaning shell 23, the cleaning tank forms a closed space relative to the cherries. The side of the cleaning tank is provided with a flow hole, and the salt water flows into the cleaning shell 23 through the flow hole, so that the salt water in the cleaning shell 23 is in a continuous flow state, and the flowing salt water can also make the cherries in the cleaning tank be washed and rolled, thereby improving the cleaning effect. When the cleaning barrel 21 rotates one circle, the cherries in the cleaning tank are soaked in salt water for 8-15 minutes. The specific soaking time of the cherries can be reset according to the actual situation, that is, the rotation speed of the cleaning barrel 21 can be reset. When the cleaning tank receiving the cherries rotates to the position of the discharge port 232, the push-out unit 24 located at the bottom of the cleaning tank is started, and the push-out unit 24 moves along the radial direction of the cleaning barrel 21, so that the cherries in the cleaning tank are pushed out, and the pushed-out cherries are discharged from the discharge port 232. A drying unit is provided on one side of the discharge port 232, and the drying unit dries the water stains remaining on the cherries, thereby increasing the storage time of the cherries. In this way, when cleaning the cherries, there is no need to use manual salvage, and the input and discharge of the cherries can be carried out in the same cleaning barrel 21, which improves the cleaning efficiency and reduces the use cost.

[0038] Reference Figure 7: A movable groove 221 is opened on the side wall of the partition plate 22 along the radial direction of the washing barrel 21, and the pushing unit 24 includes a movable block 241 arranged in the movable groove 221 and movable along the radial direction of the washing barrel 21. A through hole is opened on the movable block 241, and the through holes are arranged along the axial direction of the washing barrel 21. The distance between adjacent through holes is less than 1 cm. There are two movable blocks 241 in a washing tank. The two movable blocks 241 are respectively located on two adjacent partition plates 22. A pull rope 242 is set between the two movable blocks 241, and the pull rope 242 passes through the two through holes in the two movable blocks 241 in sequence.

[0039] Reference Figure 7 : An installation groove 243 is opened in the cleaning barrel 21 along the axial direction of the cleaning barrel 21, and a spring box 244 is respectively provided at both ends of the pull rope 242. The axis of the spring box 244 is parallel to the axis of the cleaning barrel 21, and the spring box 244 is fixedly arranged in the installation groove 243.

[0040] Reference Figure 10-12 : A threaded rod 245 is arranged in the moving groove 221 along the radial direction of the cleaning barrel 21, and the threaded rod 245 penetrates the moving block 241 along the radial direction of the cleaning barrel 21 and is threadedly matched with the moving block 241. A guide rod is arranged in parallel on one side of the threaded rod 245, and the guide rod is arranged in the moving groove 221 and penetrates the moving block 241. The guide rod and the moving block 241 are slidably matched along the radial direction of the cleaning box. A first rotating driver 246 for driving the threaded rod 245 to rotate is arranged at the end of the threaded rod 245, and bellows 247 are respectively arranged on both sides of the moving block 241, and the bellows 247 isolates the moving groove 221 from the cleaning groove.

[0041] By setting the corrugated cover 247, the cherries in the cleaning tank are prevented from entering the moving tank 221, thereby preventing the threaded rod 245 from scratching the surface of the cherries when rotating. The moving block 241 has a highest position and a lowest position when moving in the moving tank 221, and the two moving blocks 241 located in the same cleaning tank always rise and fall synchronously. When the two moving blocks 241 are at the lowest position, the volume of the cleaning tank reaches the maximum; and when the two moving blocks 241 are at the highest position, the volume of the cleaning tank reaches the minimum, and the cleaning tank is located below the discharge port 232. When the cleaning tank is located below the discharge port 232, the moving block 241 is located at the highest position, otherwise when the cleaning tank is at other positions, the moving block 241 is located at the lowest position. Through the lifting and lowering of the two moving blocks 241 in the same cleaning tank, the pull rope 242 set on the through hole forms a mesh structure at the bottom of the cleaning tank, and the mesh structure is not easy to accumulate water when the cherries are pushed out, thereby preventing the cleaning liquid in the cleaning shell 23 from being pushed out together with the cherries. The first rotary drive 246 is preferably a servo motor.

[0042] Reference Figure 2 , Figure 8 and Fig.10 : A driving unit 25 for driving the cleaning barrel 21 to rotate is provided at one end of the cleaning barrel 21, a gear ring 251 is fixedly provided at the end of the cleaning barrel 21, a gear 252 is rotatably provided on one side of the gear ring 251, the gear 252 is meshed with the gear ring 251, and a second rotation driver 253 is provided at the end of the gear 252, and the diameter of the gear 252 is smaller than the diameter of the gear ring 251.

[0043] The second rotary driver 253 is preferably a servo motor. When the second rotary driver 253 is started, the gear 252 drives the gear ring 251 to rotate. Since the diameter of the gear 252 is smaller than the diameter of the gear ring 251, the rotation speed of the gear ring 251 is slower than the rotation speed of the gear 252. In this way, a reduction mechanism is formed by the gear 252 and the gear ring 251, so that the rotation speed of the washing barrel 21 will not be too fast, ensuring that the washing barrel 21 can be controlled within 8-15 minutes after one rotation, thereby ensuring the soaking and washing effect of the cherries.

[0044] Reference Figure 3-Figure 6 A circulation unit 26 is arranged on the cleaning shell 23, and the circulation unit 26 includes a circulation box 261 arranged at the lower part of the cleaning shell 23. The circulation box 261 is connected with the cleaning shell 23. A filter screen 262 is arranged at the connection between the circulation box 261 and the cleaning shell 23. The filter screen 262 is provided with filter holes with a pore size less than 1 cm. A reflux pipe 263 is arranged between the side wall of the cleaning shell 23 and the circulation box 261 to connect the two, and a pump body 264 is arranged on the reflux pipe 263.

[0045] Usually, the size of cherries is larger than 2 cm, and the aperture of the filter 262 is set to be less than 1 cm, which ensures that the stains in the cherries can be cleaned smoothly and discharged into the circulation box 261 through the filter 262. Dust and stains enter the circulation box 261 and settle. The pump body 264 draws the cleaning liquid on the upper layer of the circulation box 261 into the cleaning shell 23 through the reflux pipe 263. The cleaning liquid flows into the cleaning shell 23 through the circulation holes on the side of the cleaning tank, so that the cleaning liquid in the cleaning shell 23 can be circulated. The flow of the cleaning liquid can turn over the cherries in the cleaning tank, thereby improving the cleaning effect of the cherries.

[0046] Reference Figure 3 and Figure 6 A drying unit 3 is provided on one side of the discharge port 232. The drying unit 3 includes a receiving tray 31 provided on one side of the discharge port 232. Through holes are evenly opened on the receiving tray 31. A fan 32 is provided on the upper part of the receiving tray 31. The fan 32 blows filtered air from top to bottom toward the receiving tray 31.

[0047] Reference Figure 3 , Figure 4, Figure 8 and Fig. 9 The receiving plate 31 is hinged in the shell 1 on one side of the discharge port 232, and an arc groove 333 is opened on the shell 1 on one side of the receiving plate 31. A swing unit 33 is arranged on one side of the receiving plate 31. The swing unit 33 includes a pushing rod 331 whose one end moves along the extension direction of the arc groove 333. The receiving plate 31 extends through the arc groove 333 and is hinged to the end of the pushing rod 331. The pushing rod 331 is used to push one end of the receiving plate 31 to swing back and forth around the hinge between the receiving plate 31 and the shell 1. A transmission unit 332 is arranged between the pushing rod 331 and the gear 252, and the gear 252 drives the pushing rod 331 to move through the transmission unit 332.

[0048] Reference Figure 8 and Fig. 9 The transmission unit 332 includes a rotating disk rotatably arranged below the push rod 331, on which a hinge column is arranged, and the lower end of the push rod 331 is hinged to the hinge column, and a synchronous wheel 3322 is respectively arranged on the rotating end and the end of the gear 252, and a synchronous belt 3323 is sleeved on the two synchronous wheels 3322, and the synchronous belt 3323 cooperates with the synchronous wheel 3322 for transmission.

[0049] When the second rotary driver 253 drives the gear 252 to rotate, the synchronous wheel 3322 arranged at the end of the gear 252 rotates synchronously with the gear 252. Under the transmission of the synchronous belt 3323, the synchronous wheel 3322 arranged at the end of the turntable 3321 drives the turntable 3321 to rotate. The turntable 3321 drives the pushing rod 331 through the hinge column, so that the pushing rod 331 drives one end of the receiving tray 31 to swing back and forth. The cherries on the receiving tray 31 roll on the receiving tray 31 when the receiving tray 31 swings, so that the surface of the cherries can be fully dried.

[0050] Reference Fig. 9 A limit baffle 34 is provided on the outer periphery of the receiving disk 31, and the limit baffle 34 is movably arranged on the outer periphery of the receiving disk 31 along the thickness direction of the receiving disk 31. The limit baffle 34 is an annular structure, and an extension rod 35 is fixedly provided at the lower part of the limit baffle 34 along the thickness direction of the receiving disk 31. The extension rod 35 penetrates the receiving disk 31 and slides with the receiving disk 31. There is a gap between the lower end of the extension rod 35 and the receiving disk 31, and a spring 36 is provided in the gap along the extension direction of the extension rod 35, and an electromagnet that can magnetically attract the extension rod 35 is provided below the extension rod 35.

[0051] When the receiving tray 31 receives the cherries and swings, the limit baffle 34 on the outer periphery of the receiving tray 31 is in an extended state. The limit baffle 34 is a ring-shaped structure. The limit baffle 34 blocks the cherries on the receiving tray 31 to prevent the cherries from rolling down from the upper part of the receiving tray 31 when rolling on the receiving tray 31. When the cherries on the receiving tray 31 need to be discharged, the electromagnet 37 arranged at the lower part of the extension rod 35 is energized. The energized electromagnet 37 attracts the extension rod 35, and the extension rod 35 drives the limit baffle 34 to descend, so that the cherries on the receiving tray 31 can be discharged through the discharge port 11. The electromagnet 37 is intermittently energized, and the intermittent time of the electromagnet 37 can be set according to actual conditions. When the cleaning tank rotates from the feed port 231 to the discharge port 232, the cherries in the cleaning tank are pushed onto the receiving plate 31 by the push-out unit 24. After the receiving plate 31 swings for a certain period of time, the electromagnet 37 is energized to make the limit baffle 34 drop, and the cherries on the receiving plate 31 fall to the bottom of the housing 1 and are discharged from the discharge port 11.

[0052] Working principle: When washing, put the cherries into the washing barrel 21 from the feed port 231 of the washing shell 23, and the cherries enter the washing tank below the feed port 231. In the process of putting the cherries into the washing tank, the washing barrel 21 is continuously in a rotating state. The time for the washing barrel 21 to rotate one circle is 8-15 minutes, and the amount of cherries put into the washing tank each time is constant. The washing shell 23 is filled with a washing liquid, and the washing liquid is preferably salt water, so that the washed cherries can be eaten directly after being fished out and packaged. After the cherries at the feed port 231 are fed, the continuously rotating washing barrel 21 drives the cleaning tank to rotate gradually. When the opening of the cleaning tank is blocked by the washing shell 23, the washing tank forms a closed space relative to the cherries. The side of the washing tank is provided with a flow hole, and the salt water flows into the washing shell 23 through the flow hole, so that the salt water in the washing shell 23 can be in a continuous flow state, and the flowing salt water can also make the cherries in the washing tank be washed and rolled, thereby improving the washing effect.

[0053] When the cleaning barrel 21 rotates one circle, the cherries in the cleaning tank are soaked in salt water for 8-15 minutes. The specific soaking time of the cherries can be reset according to the actual situation, that is, the rotation speed of the cleaning barrel 21 can be reset. When the cleaning tank receiving the cherries rotates to the position of the discharge port 232, the push-out unit 24 located at the bottom of the cleaning tank is started, and the push-out unit 24 moves along the radial direction of the cleaning barrel 21, so that the cherries in the cleaning tank are pushed out, and the pushed-out cherries are discharged from the discharge port 232. A drying unit is provided on one side of the discharge port 232, and the drying unit dries the water stains remaining on the cherries, thereby increasing the storage time of the cherries. In this way, when cleaning the cherries, there is no need to use manual salvage, and the input and discharge of the cherries can be carried out in the same cleaning barrel 21, which improves the cleaning efficiency and reduces the use cost.
