Description

Technical Field

[0001] This invention relates to the field of fruit sorting and packaging technology, specifically to a fruit sorting and cold chain packaging device. Background Technology

[0002] Harvesting, grading, packaging, and transporting fruits and vegetables are the tasks that must be completed before they enter formal storage or the market. Harvesting and post-harvest commercial processing mainly affect fruits and vegetables in two ways. Firstly, it affects the quality and storability of fruits and vegetables. For example, timely harvesting, post-harvest grading and selection, proper packaging, post-harvest pest and disease control, timely pre-cooling after harvest, and proper stacking all have a certain impact on the storage and transportation of fruits and vegetables. Secondly, it affects the marketability of fruits and vegetables. In the commercial circulation field, uniform size and specifications, attractive appearance, and appropriate and beautiful packaging are required to ensure shelf life. This necessitates that fruits be graded and packaged according to certain standards after harvest. Some fruits also require washing and waxing to improve their appearance and extend shelf life, thereby enhancing their marketability.

[0003] For common fruits such as oranges, peaches, and pears, the sorting and packaging after harvesting is particularly important as people's demands for quality continue to rise. Taking navel oranges as an example, from picking on the tree to reaching the customer, they go through several detailed steps, including waxing, labeling, and cold chain transportation, to ensure the efficiency and completeness of automated sorting and packaging. However, existing navel orange sorting and packaging production lines are not comprehensive enough, with each step being too scattered and disorganized, and there is almost no coordination or integration between the steps. This results in complex and numerous production line equipment, consuming excessive production costs and occupying a large amount of production space, and makes it difficult to efficiently complete the sorting and packaging of the fruit. Summary of the Invention

[0004] The technical problems to be solved by this invention are: the existing packaging and sorting process is too scattered and disorganized; heat treatment and waxing and labeling processes cannot be well coordinated; and the small fruit sorting process is too cumbersome, resulting in high production costs and low processing efficiency.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: a fruit sorting and cold chain packaging device, which includes a heat treatment mechanism and a waxing mechanism. The waxing mechanism includes a waxing chamber arranged obliquely in a "V" shape on one side of the heat treatment mechanism. The waxing chamber has openings at both ends, with the larger opening being the waxing inlet located at a higher position and the smaller opening being the waxing outlet located at a lower position. The waxing outlet is connected to a labeling mechanism. The upper surface of the waxing chamber has multiple wax spray nozzles evenly spaced apart, and each wax spray nozzle is equipped with a fruit wax nozzle that sprays fruit wax into the waxing chamber. The bottom of each fruit wax nozzle is connected to a wax storage tank via a wax pump. A labeling mechanism is arranged below one side of the waxing mechanism, and a cold chain conveying mechanism is arranged at the bottom of the labeling mechanism.

[0006] The beneficial effects of this invention are as follows: it organically combines multiple fruit sorting and packaging stages, continuously and compactly completing the drying and heat preservation, comprehensive waxing, and automatic labeling operations of the fruit, and finally storing and transferring them through a cold chain, thus completing a complete set of tightly coordinated, efficient, and intelligent fruit sorting and packaging processing procedures. As the fruit falls along the inclined plane from a higher entrance, it randomly passes through multiple wax spray nozzles, and during its tumbling process, all parts of its surface are evenly coated with the wax sprayed from the nozzles; thus, a uniform and efficient waxing operation is completed before reaching the lowest point.

[0007] As a further improvement of the present invention, the technical problem to be solved is that the fruit wax rolls too fast on the inclined surface and stays in the waxing chamber for too short a time.

[0008] To solve the above-mentioned technical problems, the present invention further improves the technical solution as follows: a fruit-deflecting spring is provided at the wax spray nozzle obliquely above the fruit wax nozzle; one end of the fruit-deflecting spring is connected to the wax spray nozzle through a torsion spring for resetting; the upper surface of the fruit-deflecting spring is provided with a deflection protrusion for deflecting the fruit in a certain direction; the deflection protrusion is randomly arranged on the left and right sides of the fruit-deflecting spring.

[0009] The beneficial effects of the above improvements are as follows: by setting the fruit-deflecting springs, the fruit passing over them is deflected to the sides and falls, reducing the falling speed of the fruit, increasing the path length of the fruit, and greatly increasing the time the fruit stays in the wax chamber; thereby improving the overall coverage quality of waxing.

[0010] As a further improvement of the present invention, the technical problem to be solved is: how to automatically and efficiently complete the labeling operation of fruits.

[0011] To solve the above-mentioned technical problems, the present invention further improves upon the following technical solution: the labeling mechanism includes a fruit drop opening connected to the waxing mechanism at the top, the fruit drop opening being located at the top of a vertically erected fruit drop channel, and a labeling opening being located at the bottom of the fruit drop channel; a labeling and fruit discharge channel is obliquely arranged at the lower part of the fruit drop channel on one side of the labeling opening, and the labeling and fruit discharge opening at the bottom of the labeling and fruit discharge opening is connected to a cold chain conveying mechanism; the aperture size of the fruit drop opening is larger than the standard outer diameter size of a good quality fruit, and the aperture size of the labeling opening is smaller than the standard outer diameter size of a good quality fruit; a top labeling component for labeling the fruit is provided below the labeling opening.

[0012] The beneficial effects of the above improvements are as follows: the fruit falls vertically from the fruit drop opening and the fruit drop channel; due to gravity, it hits the labeling opening and impacts the top label component below, which quickly and accurately affixes the label to the fruit.

[0013] As a further improvement of the present invention, the technical problem to be solved is: how to specifically realize the automatic labeling and resetting operation of the top label component.

[0014] To solve the above-mentioned technical problems, the present invention further improves upon the following technical solution: the top label component includes a label-receiving top block disposed directly below the label-applying opening; a push plate is connected to the bottom of the label-receiving top block via a push rod, and the push plate is disposed inside a push cylinder; a compression spring for resetting is disposed 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 disposed at the bottom of the push cylinder; a label strip with a label is placed on the label-receiving top block, and the two ends of the label strip are respectively disposed on a label strip unwinding drum and a label strip winding traction wheel; a servo rotary motor for driving its rotation and traction of the label strip to move quantitatively is connected to one side of the label strip winding traction wheel, and the trigger switch is connected to and controls the servo rotary motor.

[0015] The beneficial effects of the above improvements are as follows: the top label component resets under the action of the compression spring, lifts the fruit and slides it to one side of the labeling and fruit dispensing channel, and finally falls onto the conveyor belt in the cold chain chamber through the labeling and fruit dispensing opening. This completes the automatic and efficient labeling operation.

[0016] As a further improvement of the present invention, the technical problem to be solved is: how to specifically understand and observe the labeling results.

[0017] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a fruit drop observation window on one side of the fruit drop channel.

[0018] The beneficial effect of the above improvements is that the fruit drop process can be observed in detail through the fruit drop observation window.

[0019] As a further improvement of the present invention, the technical problem to be solved is: how the cold chain conveying mechanism specifically realizes cold chain transfer.

[0020] To solve the above-mentioned technical problems, the present invention further improves the technical solution by adopting the following: the cold chain conveying mechanism includes a conveyor belt disposed below the labeling mechanism, the conveyor belt is disposed in the cold chain chamber and one end of the cold chain chamber is provided with a cold-delivery fruit packaging port for connecting to the subsequent packaging process.

[0021] The beneficial effect of the above improvements is that they enable rapid cold chain storage of fruits.

[0022] As a further improvement of the present invention, the technical problem to be solved is: how the heat treatment structure dries and heat-preserves fruits that have been cleaned and sterilized.

[0023] To solve the above-mentioned technical problems, the present invention further improves the technical solution as follows: the heat treatment mechanism includes a vertically arranged fruit feeding channel, and a heat treatment fruit inlet is opened on one side of the lower part of the fruit feeding channel; a hot air outlet is provided at the bottom of the fruit feeding channel, and a hot air blower is connected to the hot air outlet; a good product storage box is connected to the top of the fruit feeding channel and is located above the washing chamber.

[0024] The beneficial effects of the above improvements are as follows: hot air is introduced through the fruit delivery channel, which is just slightly larger than the standard fruit size, and blows the fruit upward in the channel, thus completing the drying of the fruit in the process; at the same time, the good product storage box can provide a heat preservation environment for the dried fruit.

[0025] As a further improvement of the present invention, the technical problem to be solved is that the good product storage box is inconvenient to rotate and flip.

[0026] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a handle for lifting on one side of the good product storage box.

[0027] The beneficial effect of the above improvements is that the handle design helps to flip the good product storage box.

[0028] As a further improvement of the present invention, the technical problem to be solved is: the fruit may fall into the hot air blower through the hot air nozzle.

[0029] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a partition mesh plate for isolation and protection at the hot air outlet.

[0030] The beneficial effect of the above improvements is that they provide isolation and protection for the hot air outlet.

[0031] As a further improvement of the present invention, the technical problem to be solved is: in addition to the size of the fruit, dried fruit with too low internal moisture content does not meet the standard of good fruit and needs to be sorted and removed.

[0032] To solve the above-mentioned technical problems, the present invention further improves upon the following technical solution: The secondary fruit sorting mechanism includes a speed measuring instrument mounted on the inner wall of the middle section of the fruit feeding channel. The speed measuring instrument is connected to and controls a linear motor mounted on one side of the upper part of the fruit feeding channel via a connecting line. The fruit feeding channel has a secondary fruit sorting port at the linear motor. A guide plate that can be flipped into the fruit feeding channel is provided inside the secondary fruit sorting port. The bottom of the guide plate is movably connected to the fruit feeding channel via a hinge seat, and the back of the guide plate is movably hinged to the front end of the linear motor via a rotating push rod. A good fruit channel is connected to the upper part of the fruit feeding channel on the side slightly lower than and away from the secondary fruit sorting port, and a dry fruit channel is connected to the top of the fruit feeding channel.

[0033] The beneficial effects of the above improvements are as follows: A secondary fruit sorting mechanism is installed in the fruit conveying channel. Fruits of similar size will have significantly lower quality than normal good fruit if their internal moisture content is too low. They will be blown upwards by hot air, and their speed in the channel will also be significantly different. Based on this characteristic, a speed measuring instrument is installed in the channel to measure the speed of fruits that exceed the set value. These fruits are considered to be of lower quality, i.e., with insufficient internal moisture. Then, a guide plate guides the good fruit to the good fruit channel and the dry fruit to the dry fruit channel, thereby completing the secondary fruit sorting operation. Attached Figure Description

Each wax spraying nozzle 52 is equipped with a fruit wax nozzle 53 that sprays fruit wax into the waxing chamber 51. The bottom of the fruit wax nozzle 53 is connected to a wax storage tank 54 through a wax pump 55. A labeling mechanism 6 is arranged below one side of the waxing mechanism 5, and a cold chain conveying mechanism 7 is arranged at the bottom of the labeling mechanism 6. The small fruit outlet 215 is connected to a secondary fruit storage bin 8 through a small fruit channel 216. The heat treatment mechanism 4 includes a vertically arranged fruit feeding channel 42, with a heat treatment fruit inlet 421 on one side of the lower part of the fruit feeding channel 42; a hot air outlet 411 is provided at the bottom of the fruit feeding channel 42, and a hot air blower 41 is connected to the hot air outlet 411; and a good product storage box 44 is connected to the top of the fruit feeding channel 42 above the washing chamber 11. The secondary fruit sorting mechanism 23 includes a speed measuring instrument 238 installed on the inner wall of the middle part of the fruit feeding channel 42.

A dry fruit channel 237 is connected to the top of the fruit feeding channel 42.

[0064] During operation, the fruit enters the heat treatment mechanism for drying and heat preservation, and is finally transferred to the good-quality storage box. The secondary fruit sorting mechanism separates dried fruit from good-quality fruit; dried fruit and small fruit enter the secondary fruit storage bin for juicing and other processing purposes. By flipping the good-quality storage box, the good-quality fruit slides down the inclined surface of the waxing chamber from the upper side of the waxing mechanism, completing a thorough waxing operation. The fruit then falls vertically from the fruit drop outlet through the fruit drop channel. Due to gravity, it hits the labeling opening, impacting the top labeling component below, which quickly and accurately affixes the label to the fruit. The top labeling component then resets under the action of a compression spring, lifting the fruit and sliding it down the labeling outlet channel to one side, finally falling onto the conveyor belt in the cold chain chamber. This completes the automatic and efficient labeling operation.
