Abstract
A precise release hole making apparatus for a sustained release package of a grape preservative, comprising a machine frame (1), a winding and unwinding mechanical transmission mechanism (2), a pulse laser generator (3), a laser tube cooling system (4), and a smoke and paper scrap sucking apparatus (5). The winding and unwinding mechanical transmission mechanism (2) is mounted on the machine frame (1). The pulse laser generator (3) is vertically mounted on the machine frame (1) and perpendicular to a frame platform surface. The laser tube cooling system (4) is a closed cooling water circulation system for cooling a laser tube to ensure normal operation thereof. The smoke and paper scrap sucking apparatus (5) uses a vacuum pump and a pipeline to suck away smoke and paper scraps generated by laser hole making to keep clean the environment and a hole-make working surface. The apparatus greatly reduces costs by omitting a manual hole-drilling procedure before the use of a preservative, greatly improves the controllable release property of a grape preservative SO2, and improves the grape preservation quality and reliability.

Multiple advanced technologies such as the mechanical technology, the electronic technology, the laser technology and the sensing technology are adopted in the precise release hole making apparatus, which is used for a slow-release package of grape preservatives.
BACKGROUND
[0002] Grape is a type of berry, which is easily affected by decaying during postharvest storage and transportation. Measures for solving the above problems include keeping low temperature and high humidity while using a preservative during the storage and transportation. The low-temperature condition is generally provided by a cold storage and a refrigerator truck. The high-humidity condition is generally provided by a plastic film package.
The preservative is generally a slow-release preservative tablet which is mainly made of pyrosulfite. In order to preserve the grapes while preventing the grapes from being harmed by SO2, and to make sure that residual SO2 in the pulp is in the national standard allowed range, the slow-release preservative tablet is packaged by a specialized packaging paper on which precise holes are pre-made. This method can also ensure precise and sustained release of SO2 Therefore, a key step of using the grape preservative is to control the release rate of SO2.

normal voltage ranges from 220V-5% to 220V+5%, and a normal operating current is 0.6A.
[0038] The diameter and regularity of the hole and the distance between the holes were checked. The hole diameter, regularity and distance are adjusted as needed.
After holes are made for a roll of paper, another roll of paper is installed, and the parameters remain unchanged.
[0039] The grape preservative is packaged with the packaging paper having holes made precisely thereon through a tablet packaging machine. The specification is as follows: two 0.5g preservative tablets are packaged in each package, four holes with the diameter of 0.2mm are formed on each package, with the holes being distributed on both sides of the package.
[0040] Postharvest kyoho grapes are put into a plastic porous packaging box, which is provided with a liner layer of a polyethylene preservative bag with the thickness of 0.3mm.
3.5kg to 5kg of grapes are put into each polyethylene preservative bag, and then the opened polyethylene preservative bags are taken into a 0 C cold storage to precool the grapes to 0 C
to 1 C. For each kilogram of grapes, two packs of slow-release grape preservatives with precise holes in the wrapping paper are provided. The polyethylene preservative bag is tightly enclosed and stored at a temperature from 0 C to -1 C. By sampling and testing the gas, an active ingredient content of the preservative in the preservative bag ranges from 15ppm to 25ppm, and the grapes are not bleached. After storage for four months, rotting rate is less than 3%.
[0041] Third embodiment [0042] A method for using the precise release hole making apparatus for the slow-release package of grape preservatives is described below.
[0043] In step (1), slow-release packaging paper for grape preservatives is installed on an unwinding air inflatable shaft of the winding and unwinding mechanical transmission mechanism 2, and an end of the paper is winded on a winding rod through a guide wheel, where the paper is kept smooth.
[0044] In step (2), a frequency of the variable-frequency drive is adjusted to gradually increase a paper delivering speed to approximately 1m/s.
[0045] In step (3), the smoke and paper particle suction apparatus 5 and the laser tube cooling system 4 are turned on.
[0046] In step (4), the pulse laser generator 2 is turned on, and the frequency, the number of pulses and the power are set as required.
[0047] In step (5), generated holes are checked, and operating parameters are adjusted as required.
[0048] Fourth embodiment [0049] Comparison test (taking grapes as an example) Comparison item Existing apparatus Apparatus according to the present disclosure Slow-release packaging paper No hole are made in Holes are made in advance for grape preservatives advance Release concentration of SO2 l-30PPm 3-10ppm Preservation quality (rate of 88-93% 90-95%
intact fruit) Preservation life of grapes 120 days 150 days Shelf life 5 days 7 days [0050] Conclusion [0051] (1) No hole is made on the existing slow-release packaging paper for grape preservatives in advance, and the packaging paper is pricked manually using the number-two pin after the grape preservative tablets are packaged before the grape preservative is used, which is time-consuming, labor-intensive, and less accurate. With the precise release hole making apparatus, holes are made on the packaging paper before packing the grape preservative tablets. In this way, a process of manually making holes before using preservatives is omitted, thus the cost is greatly reduced.
[0052] (2) With the precise release hole making apparatus according to the present disclosure, a precise number of holes with the precise size are made at precise location, thereby better controlling release of the SO2 grape preservative, which improves quality and reliability of preservation of the grapes.

Changes of equivalent structures and equivalent flows made based on the content in the specification of the present disclosure or directly and indirectly applied to other related technical field are contained in the patent protection scope of the present disclosure.
