Description

Technical Field

[0001] The present invention relates to the technical field of fruit sorting and packaging, in particular to a fruit sorting and packaging production line. Background Art

[0002] Harvesting, grading, packaging, and transportation of fruits and vegetables are essential tasks before they enter formal storage or market. Harvesting and post-harvest commercialization processes primarily impact fruit production in two key ways. One aspect affects fruit and vegetable quality and storability. These include appropriate harvesting times, post-harvest grading and selection, proper packaging, post-harvest pest and disease control, timely post-harvest pre-cooling, and appropriate palletizing. This impacts the marketability of fruits and vegetables. In the commodity distribution sector, consistent size and specifications, attractive appearance, and appropriate packaging are essential to ensure shelf life. This requires that post-harvest fruit be graded and packaged according to specific standards. Some fruits also require washing and waxing to enhance their commercial qualities, both for aesthetic appeal and shelf life.

[0003] As people's demand for quality continues to increase for common fruits such as oranges, peaches, and pears, sorting and packaging them after harvest is becoming increasingly important. Take navel oranges as an example. From being picked from the tree to the hands of customers, they must go through multiple detailed steps, including cleaning and sterilization, drying and waxing, labeling and packing, to ensure the efficiency and completeness of automated sorting and packaging. However, the existing navel orange sorting and packaging production line is not comprehensive enough. The various links are too scattered and disorganized, and there is almost no coordination and integration between the links. This makes the production line equipment complex and numerous, consuming excessively high production costs while occupying a large amount of production space. It also makes it difficult to efficiently complete the sorting, packaging and processing of the fruit. Summary of the Invention

[0004] The technical problems to be solved by the present invention are: the existing packaging and sorting links are too scattered and messy; the cleaning, heat treatment, sterilization, waxing and labeling links cannot be deeply coordinated; the small fruit sorting link is too complicated, resulting in high production costs and low processing efficiency.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is: a fruit sorting and packaging production line, which includes a cleaning mechanism, a sorting mechanism and a control panel; the sorting mechanism includes a small fruit sorting mechanism, a large fruit sorting mechanism and a secondary fruit sorting mechanism, and the small fruit sorting mechanism is arranged in a cleaning chamber of the cleaning mechanism; the small fruit sorting mechanism includes a lifting platform that can move up and down and is arranged in the cleaning chamber, and a linear drive mechanism for driving the lifting platform is provided at the bottom of the lifting platform; the upper surface of the linear drive mechanism is provided with a fruit falling slope inclined to one side, and a small fruit outlet is opened on the upper part of the cleaning chamber near the lower end of the fruit falling slope; a plurality of sorting columns are arranged vertically from high to low on the linear drive mechanism, and the lower sorting column is arranged on the side away from the small fruit outlet; the adjacent sorting columns are arranged The fruit outlet is evenly spaced, and the interval size is the standard radial size for small fruit sorting; a fruit outlet is provided on the upper part of the cleaning chamber near the lower sorting column; the fruit outlet is connected to a sterilization mechanism, and the sterilization mechanism is connected to the top of the waxing mechanism through a heat treatment mechanism; a labeling mechanism is provided below one side of the waxing mechanism, and a cold chain conveying mechanism is provided at the bottom of the labeling mechanism; the small fruit outlet is connected to a secondary fruit storage bin through a small fruit channel; the control panel connects and controls the cleaning mechanism, sorting mechanism, sterilization mechanism, heat treatment mechanism, waxing mechanism, labeling mechanism and cold chain conveying mechanism; the cold chain conveying mechanism includes a conveyor belt provided below the labeling mechanism, the conveyor belt is provided in the cold chain chamber, and a cold delivery fruit packaging port for connecting to subsequent packaging links is provided at one end of the cold chain chamber.

[0006] The beneficial effects of the present invention are as follows: multiple fruit sorting and packaging links are organically combined, and the initial sorting of fruit sizes is completed through the orderly arranged fruit dropping slopes and sorting columns during the efficient cleaning process; then, the orderly connected sterilization mechanism, heat treatment mechanism, waxing mechanism and labeling mechanism are used to continuously and compactly complete the secondary sorting, efficient sterilization, drying and heat preservation, comprehensive waxing and automatic labeling operations of the fruits, and finally storage and transportation are carried out through the cold chain link, thereby completing a complete set of closely coordinated, efficient and intelligent fruit sorting and packaging processing procedures.

[0007] As a further improvement of the present invention, the technical problem to be solved is: how to specifically realize bubbling cleaning of fruits by the cleaning device while sorting.

[0008] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the cleaning mechanism includes a fruit cleaning inlet arranged on the upper side of the cleaning chamber and a bubbling chamber arranged in the lifting platform, and the bubbling chamber is connected to the high-pressure blower through a blast pipe; the bubbling chamber is evenly spaced on the fruit falling slope and is provided with bubbling holes for blasting bubbles, and a cleaning liquid level line is provided in the cleaning chamber slightly below the small fruit outlet to indicate the highest position of the cleaning liquid surface; a water exchange pipe for replacing cleaning water is provided on the lower side of the cleaning chamber, and a water pump is provided on the water exchange pipe.

[0009] The beneficial effect of the above improvement is that the sorting device drives the fruits up and down for sorting, and at the same time, bubbles are bulged from the bottom to complete the thorough cleaning of the surface of the fruits.

[0010] As a further improvement of the present invention, the technical problem to be solved is that the up and down movement of the lifting platform will cause the level of the cleaning water to change, thereby affecting the water inlet of the fruit outlet or incomplete cleaning.

[0011] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: a cleaning observation window is opened outward on one side of the cleaning chamber; the linear drive mechanism is a cylinder; the interior of the sorting column is hollow and connected to a bubbling chamber, and the side wall of the sorting column is opened with a bubbling side hole for bubbling bubbles; the fruit outlet is provided with a limit plate on the side close to the lifting platform, and the lifting platform is provided with a limit protrusion matching the limit plate directly below the limit plate.

[0012] The beneficial effects of the above improvements are: setting a cleaning liquid level line to ensure that the liquid level is always lower than the fruit outlet; at the same time, in order to prevent dirt particles from clogging the bubbling holes during the cleaning process, the sorting column is hollowed and bubbling side holes are opened on the side; and by setting limit protrusions and limit plates, the lifting platform is prevented from rising too high, thereby affecting the normal sorting process.

[0013] As a further improvement of the present invention, the technical problem to be solved is: how can the sterilization mechanism specifically realize the comprehensive sterilization operation of the fruit?

[0014] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the sterilization mechanism includes a sterilization chamber, a sterilization fruit inlet is provided on one side of the upper part of the sterilization chamber and is connected to the fruit outlet, and a sterilization fruit outlet is provided at the bottom of the sterilization chamber and is connected to the heat treatment mechanism; a plurality of downward-spraying atomizing nozzles are provided on the top of the sterilization chamber, and the atomizing nozzles are connected to a sterilization liquid storage tank through a liquid flow pump outside the sterilization chamber; a plurality of fruit-dropping inclined plates are evenly spaced in a zigzag shape from top to bottom in the sterilization chamber just below the atomizing nozzles, and the bottom end of the higher fruit-dropping inclined plate faces the upper surface of the lower fruit-dropping inclined plate; buffer belts for buffering protection are evenly spaced laterally on the fruit-dropping inclined plates.

[0015] The beneficial effect of the above improvement is that the fruit rolls down from the upper part of the sterilization chamber, and after passing through the sterilization liquid sprayed by the atomizing nozzle, it rolls repeatedly during the falling process to ensure that the surface is completely in contact with the sterilization liquid.

[0016] As a further improvement of the present invention, the technical problem to be solved is: fruits that are too large also need to be sorted, so as to ensure that the fruits are of uniform size and more standardized quality.

[0017] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the sorting mechanism is provided with a large fruit sorting mechanism at the sterilization fruit outlet, and the large fruit sorting mechanism includes a large fruit sorting port arranged on the sterilization fruit outlet; a large fruit channel is provided below the large fruit sorting port at the bottom of the sterilization chamber, and the large fruit channel is connected to a large fruit storage bin; the opening size of the large fruit sorting port is the standard radial size for large fruit sorting.

[0018] The beneficial effects of the above improvements are: a large fruit sorting port with an opening size that is the standard radial size for large fruit sorting is provided, so that the fruits that were originally to pass through the sterilization outlet port can be size-screened again; oversized fruits will be intercepted and fall down into the large fruit channel, and finally sent to the large fruit storage bin for standby use.

[0019] As a further improvement of the present invention, the technical problem to be solved is: how the heat treatment structure can dry and heat-preserve the fruits that have been cleaned and sterilized.

[0020] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the heat treatment mechanism includes a vertically arranged fruit delivery channel, a heat treatment fruit entrance is opened on one side of the lower part of the fruit delivery channel, and the heat treatment fruit entrance is connected with the sterilization mechanism through the fruit passing channel; a hot air outlet is provided at the bottom of the fruit delivery channel, the hot air outlet is connected to a hot air blower, and a partition mesh plate for partitioning and protection is provided at the hot air outlet; the top of the fruit delivery channel is connected to a good product storage box arranged above the cleaning chamber, and a handle for lifting is provided on one side of the good product storage box.

[0021] The beneficial effects of the above improvements are: hot air is blown into the fruit delivery channel which is just slightly larger than the standard fruit size to blow the fruit upward in the channel, and the fruit is dried in the process; at the same time, the good product storage box can provide a hot and fresh environment for the dried fruit.

[0022] As a further improvement of the present invention, the technical problem to be solved is: in addition to the external size of the fruit, dried fruits with too low internal moisture do not meet the standards of good fruit and need to be sorted and removed.

[0023] In order to solve the above technical problems, the further improved technical scheme of the present application is that the sorting mechanism is provided with a sub-fruit sorting mechanism between the fruit conveying channel and the good fruit storage box; the sub-fruit sorting mechanism comprises a speed tester arranged on the inner wall of the middle part of the fruit conveying channel, the speed tester is connected with and controls a linear motor arranged on one side of the upper part of the fruit conveying channel through a connecting line; the fruit conveying channel is provided with a sub-fruit sorting opening at the linear motor, and a guide rotating plate which can be turned inwards into the fruit conveying channel is arranged in the sub-fruit sorting opening; the bottom of the guide rotating plate is movably connected with the fruit conveying channel through a hinge seat, and the back of the guide rotating plate is movably hinged with the front end of the linear motor through a rotating push rod; a good fruit channel is communicated with the upper part of the fruit conveying channel at a position slightly lower than the sub-fruit sorting opening and away from the sub-fruit sorting opening, and a dry fruit channel is communicated with the top of the fruit conveying channel; the good fruit channel leads to the good fruit storage box, and the dry fruit channel leads to the sub-fruit storage bin.

[0024] The improved beneficial effect is that the sub-fruit sorting mechanism is arranged in the fruit conveying channel, if the internal moisture of the fruit with similar size is too low, the quality of the dry fruit will be obviously lower than that of the normal good fruit, and the speed of the dry fruit in the channel will also be obviously different when the dry fruit is moved upwards by the hot air; therefore, the speed tester is arranged in the channel to determine the dry fruit with low quality, i.e. the fruit with insufficient internal moisture, which has a speed higher than the set speed value; then, the guide rotating plate is used to guide the good fruit to the good fruit channel and guide the dry fruit to the dry fruit channel, so that the sorting operation of the sub-fruit is completed.

[0025] As a further improvement of the present application, the technical problem to be solved is how to realize the uniform wax spraying operation of the fruit by the waxing mechanism.

[0026] In order to solve the above technical problems, the further improved technical scheme of the present application is that the waxing mechanism comprises a waxing chamber arranged in a "V" shape and obliquely arranged on one side of the heat treatment mechanism; the waxing chamber is open at both ends, one end with a larger opening is a waxing fruit inlet and is arranged at a higher position, and the other end with a smaller opening is a waxing fruit outlet and is arranged at a lower position, and the waxing fruit outlet is communicated with a labeling mechanism; a plurality of wax spraying openings are uniformly and interval ly arranged on the upper surface of the waxing chamber, and a fruit wax nozzle for spraying into the waxing chamber is arranged at each wax spraying opening; and a wax storage barrel is connected with the fruit wax nozzle through a wax pump at the bottom of the fruit wax nozzle.

[0027] The improved beneficial effect is that when the fruit falls along the inclined surface from the higher inlet, it will pass through the plurality of wax spraying openings at random, and the wax liquid sprayed by the fruit wax nozzle is uniformly adhered to the surface of the fruit during the turning process; so that the uniform and efficient waxing operation is completed before the fruit reaches the lowest end.

[0028] As a further improvement of the present application, the technical problem to be solved is that the rolling speed of the fruit wax on the inclined surface is too fast, and the time of the fruit wax staying in the waxing chamber is too short.

[0029] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: a fruit deflecting spring is provided at the wax spray port obliquely above the fruit wax nozzle; one end of the fruit deflecting spring is connected to the wax spray port through a torsion spring for resetting, and a deflection protrusion is provided on the upper surface of the fruit deflecting spring for offsetting the direction of the fruit; the deflection protrusions are randomly arranged on the left and right sides of the fruit deflecting spring.

[0030] The beneficial effects of the above improvements are: by setting the fruit-deflecting spring piece, the fruit passing over it deviates to both sides and falls, which reduces the falling speed of the fruit, increases the length of the path the fruit passes through, and greatly increases the time the fruit stays in the wax chamber; thereby improving the comprehensive coverage quality of waxing.

[0031] As a further improvement of the present invention, the technical problem to be solved is: how to automatically and efficiently complete the labeling operation on fruits.

[0032] In order to solve the above technical problems, the present invention further improves the technical solution adopted as follows: the labeling mechanism includes a fruit drop port connected to the waxing mechanism at the top, the fruit drop port is arranged at the top of the vertically set fruit drop channel, and the fruit drop channel is provided with a labeling port at the bottom; the lower part of the fruit drop channel is provided with a labeling fruit outlet channel obliquely on one side of the labeling port, and the labeling fruit outlet at the bottom of the labeling fruit outlet is connected to the cold chain conveying mechanism; the aperture size of the fruit drop port is larger than the standard size of the outer diameter of good fruit, and the aperture size of the labeling port is smaller than the standard size of the outer diameter of good fruit; a top label piece for labeling fruit is provided below the labeling port, and the top label piece includes The present invention comprises a label receiving top block arranged just below the label sticking port; the bottom of the label receiving top block is connected to a push plate through a push rod, and the push plate is arranged in a push cylinder; a compression spring for resetting is arranged between the bottom of the push plate and the bottom of the push cylinder, and a trigger switch for being triggered by the push plate is arranged at the bottom of the push cylinder; a label with a label is placed on the label receiving top block, and the two ends of the label are respectively arranged on the label unwinding drum and the label winding traction wheel; a servo rotating motor for driving it to rotate and pulling the label to move quantitatively is connected to one side of the label winding traction wheel, and the trigger switch is connected to and controls the servo rotating motor; a fruit falling observation window is provided on one side of the fruit falling channel.

[0033] The beneficial effects of the above improvements are as follows: Fruit falls vertically from the fruit drop port into the fruit drop channel; due to gravity, it hits the labeling port, impacting the label lifter below, quickly and accurately attaching the label to the fruit. The label lifter then resets under the action of the compression spring, lifting the fruit and sliding it toward the labeling and fruit discharge channel on one side, finally falling through the labeling and fruit discharge port onto the conveyor belt in the cold chain room, completing the automatic and efficient labeling operation.

[0067] When the device is working, the first harvested fruits enter the cleaning chamber through the fruit cleaning inlet. The lifting platform in the cleaning chamber rises and falls, and the cleaning water is driven by the bubbles emerging from the bubbling chamber to clean the fruits; the larger fruits are lifted by the sorting columns and slide down to the fruit outlet along the inclined surface formed at the top; the smaller fruits fall between the gaps of the sorting columns, fall into the small fruit outlet through the fruit falling inclined surface and enter the secondary fruit storage bin through the small fruit channel; the fruits coming out of the fruit outlet are cleaned by the sterilization mechanism and sorted by the large fruit sorting mechanism, and then enter the heat treatment mechanism to complete drying and heat preservation; finally, they are transferred to the good product storage box. The inferior fruit sorting mechanism separates dry fruit from good fruit, which are then transferred to the inferior fruit storage bin along with small fruit for juicing and other processing purposes. By flipping the good fruit storage bin with a handle, the good fruit inside slides down the waxing mechanism's upper side along the inclined surface of the waxing chamber, completing the waxing process. The fruit then drops vertically from the fruit drop opening into the fruit drop channel. Gravity forces it onto the labeling opening, impacting the label lifter underneath, quickly and accurately attaching the label to the fruit. The label lifter then resets under the action of a compression spring, lifting the fruit and sliding it down the labeling channel to the side. Finally, it drops onto the cold chain chamber's conveyor belt through the labeling opening, completing an automatic and efficient labeling operation.
