Description

Technical Field

[0001] This invention relates to a storage device, specifically a novel cocoon storage device. Background Technology

[0002] Silkworm cocoons are the protective sacs of silkworms during their pupal stage, containing the pupa. The cocoon layer can be used for silk reeling, and the cocoon shell and waste silk after reeling can be used as raw materials for silk floss and spun silk. Because silkworm production is highly seasonal, with silkworms spinning cocoons in a concentrated period, silkworm cocoon purchasing units (cocoon stations) must dry all cocoons at high temperatures within one week. Otherwise, moth emergence will occur, forming "moth-mouthed cocoons." The silkworm pupa inside the cocoon transforms into a moth, secreting an alkaline liquid to soften the cocoon, then pushes out a hole and slowly crawls out—this is the "moth-mouthed cocoon." After emerging, the moth mates and lays eggs, which become the next generation of silkworms. Therefore, after the cocoons are purchased, they are dried first to kill the silkworm pupae and prevent the pupae from transforming into moths, thus preserving the integrity of the cocoon and its value.

[0003] The current method of high-temperature drying kills live pupae inside the cocoons. The sericin protein on the outer layer of the cocoon silk denatures due to the high temperature, leading to a decrease in the unwinding rate during reeling and directly affecting the yield of raw silk. Therefore, low-temperature cold storage of silkworm cocoons has emerged as a method for long-term storage. The commonly used low-temperature storage device is a cold storage warehouse. While cold storage warehouses have a large area and can store large quantities of silkworm cocoons, controlling the internal temperature and humidity is difficult, and significant temperature or humidity differences may occur within the internal space. Furthermore, during low-temperature storage, it is necessary to sample and observe changes in the cocoons within the cold storage warehouse at certain intervals to adjust the refrigeration conditions accordingly. Sampling in existing cold storage warehouses is inconvenient. Due to the large space, manual opening is required for sampling. Allowing personnel to enter the cold storage warehouse necessitates creating a large opening, which can easily alter the internal environment. Moreover, the low temperature inside the cold storage warehouse for manual sampling can cause discomfort and is detrimental to the health of the personnel.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the cold storage warehouses used for storing silkworm cocoons are large in size, making it difficult to control the storage conditions and to take samples. Sampling is also very difficult, requiring sampling personnel to enter the warehouse, which is detrimental to the health of the sampling personnel. The purpose is to provide a new type of cocoon storage device to solve the above problems.

[0006] The embodiments of the present invention are implemented as follows:

[0007] A novel cocoon storage device includes multiple sequentially connected refrigerated cabinets, each connected to a cold air generator. Inside each cabinet is a horizontally placed turntable, connected to a motor via a lower rotating shaft. The motor is mounted at the bottom of the cabinet. Below the turntable is a horizontally placed support plate, which serves as a filter plate. The support plate is fixedly connected to the inner wall of the cabinet. The turntable rests on the support plate, with the upper end of the rotating shaft passing through the support plate and fixedly connected to the bottom of the turntable. The rotating shaft is rotatably connected to the support plate. Multiple grooves are provided on the top surface of the turntable, each containing a [missing information - likely a type of filter]. The refrigerator has multiple evenly distributed ventilation holes on its walls. An iron block is installed on the top of the refrigerator. The top of the refrigerator has a through hole located above a groove on the edge of the turntable. A bracket is installed on the top of the refrigerator, and a vertically mounted electric push rod is mounted on the bracket. A horizontally placed electromagnetic chuck is installed at the bottom of the electric push rod. The electromagnetic chuck is located above the through hole, which allows the electromagnetic chuck to pass through. Under the push of the electric push rod, the electromagnetic chuck passes down through the through hole and connects to the refrigerator below the through hole. The refrigerator is then attracted to the electromagnetic chuck by the iron block on top.

[0008] This invention uses multiple small-space refrigerated cabinets to replace the existing large-space integrated cold storage. Furthermore, this invention adds a mechanical sampling device to the refrigerated cabinets to replace manual sampling, thus solving the problems of inconvenient sampling and difficulty in controlling the internal environment of existing silkworm cocoon cold storage devices.

[0009] In this invention, the refrigerated cabinet provides a low-temperature environment for storing silkworm cocoons. A support plate supports a turntable, which rotates in place under the drive of a motor. Grooves on the turntable are used to place refrigerated boxes. These boxes, equipped with ventilation holes, are used to hold the silkworm cocoons requiring refrigeration; the ventilation holes are essential to prevent the silkworm pupae inside from dying due to lack of oxygen. An iron block is used to attach the cocoons to an electromagnetic chuck. The lifting and lowering of the electromagnetic chuck is controlled by an electric push rod. The refrigerated box is attached to the electromagnetic chuck by the iron block. Under the action of the electric push rod, the electromagnetic chuck rises, allowing the refrigerated box to be removed from the through-hole at the top of the refrigerated cabinet, completing the sampling process. This process eliminates the need for manual sampling, saving time and effort. The electric push rod is electrically driven, allowing for rapid ascent and descent, significantly increasing sampling speed compared to manual sampling. After sampling, the through-hole is covered with a cover plate or similar structure to prevent external environmental influence from affecting the internal environment of the refrigerated cabinet. After one sampling, the turntable is rotated to position other refrigerated boxes below the through-hole, allowing for secondary sampling using an electromagnetic chuck. The more samples collected, the more accurate the assessment of changes in the silkworm cocoons. However, excessive sampling is not recommended, as the collected samples cannot be refrigerated again, and excessive sampling reduces the storage capacity of the silkworm cocoons. The refrigerated boxes used to hold the silkworm cocoons in this invention are small in size, thus the electromagnetic chucks used are also small in size, resulting in a naturally small through-hole diameter. During sampling, the external environment has virtually no impact on the internal environment of the refrigerated cabinet in a short period of time.

[0010] The top of the air-conditioned cabinet is equipped with a cover plate that blocks the through holes. The cover plate is placed on the top surface of the air-conditioned cabinet and is slidably connected to the air-conditioned cabinet. A horizontal hydraulic cylinder is installed on one side of the cover plate. The telescopic shaft of the horizontal hydraulic cylinder is connected and fixed to the top of the cover plate through a vertically placed short shaft. Under the action of the horizontal hydraulic cylinder, the cover plate makes a linear reciprocating motion on the top surface of the air-conditioned cabinet.

[0011] This invention features a cover plate for sealing through holes. A horizontal hydraulic cylinder performs a lateral telescopic movement, causing the cover plate to reciprocate linearly in the horizontal direction. When sampling is required, the horizontal hydraulic cylinder shortens its telescopic shaft, pulling the cover plate towards the cylinder to expose the through hole. Under the action of an electric push rod, an electromagnetic chuck can then enter the refrigerator through the through hole to pick up the refrigerated box for sampling. After sampling, the horizontal hydraulic cylinder extends its telescopic shaft, moving the cover plate towards the through hole. Once the cover plate completely covers the through hole, it seals it. The horizontal liquid oxygen cylinder is then closed. Under external force, the cover plate is unlikely to shift, resulting in a good sealing effect on the through hole. This invention uses a horizontal hydraulic cylinder to place and remove the cover plate, making operation simple.

[0012] Each air-conditioned display case is equipped with a temperature and humidity sensor. These sensors measure the temperature and humidity inside the display case, providing a monitoring function for the internal environment.

[0013] The refrigerator box is a hollow cylindrical tube. Inside the refrigerator box, there is a vertically placed insert rod that can be detachably connected. Multiple shelves are installed on the insert rod. Silkworm cocoons are evenly laid on each shelf. All shelves are arranged sequentially along the axial direction of the insert rod. The bottom of the refrigerator box is provided with a first slot for the lower end of the insert rod to be inserted.

[0014] In this invention, a refrigerated box is equipped with multiple shelf panels, which can evenly spread a large number of silkworm cocoons. A single sampling can retrieve a large number of silkworm cocoons, providing a reference for the preservation status of the silkworm cocoons. The insert rod is used to support the shelf panels, facilitating their assembly and disassembly. When placing silkworm cocoons, the shelf panels are first removed, and the silkworm cocoons are evenly spread on each shelf. Then, the insert rod is lifted and vertically inserted into the refrigerated box, allowing all the shelf panels to be quickly placed into the refrigerated box at once. When removing the silkworm cocoons, the insert rod is pulled outwards, allowing all the shelf panels to be removed at once, enabling rapid loading and unloading.

[0015] The top of the refrigerator box is detachably connected to a lid, with an iron block installed on top of the lid. A second slot is installed at the bottom of the lid for inserting the upper end of the insertion rod.

[0016] In this invention, the top cover is used to seal the opening at the top of the refrigerator box to prevent the silkworm cocoons from falling out of the top opening of the refrigerator box. The cover plate and the refrigerator box can be connected by threads. The second slot on the top cover and the first slot at the bottom of the refrigerator box fix the plug rod between the two. During the rotation of the turntable, the plug rod will not shake and will not shake the silkworm cocoons on the shelf off.

[0017] A rolling bearing connects the rotating shaft and the support plate, allowing them to rotate rotatably. The rolling bearing reduces wear on the rotating shaft.

[0018] The internal temperature of the refrigerated display case is 4-8℃, and the relative humidity is 60-70%. This environment of 4-8℃ and 60-70% relative humidity is the optimal condition for storing silkworm cocoons.

[0019] The shelf has grooves for placing silkworm cocoons, and the grooves are evenly distributed on the shelf.

[0020] The bracket and the air conditioner can be detachably connected by screws.

[0021] The cover plate is a circular plate, and its diameter is larger than that of the through hole. This larger diameter ensures that the cover plate can completely seal the through hole, improving its sealing performance.

[0022] The beneficial effects of the embodiments of the present invention are:

[0023] 1. The present invention provides a novel cocoon storage device that uses multiple small-space refrigerated cabinets instead of the existing integrated large-space cold storage. The internal space of the refrigerated cabinet is small, and the internal temperature and humidity are easy to adjust, which can ensure that the temperature and humidity of various locations inside are basically the same.

[0024] 2. The present invention provides a novel cocoon storage device by adding a mechanical sampling device to the refrigerated cabinet, which replaces manual sampling and solves the problem of inconvenient sampling in existing cocoon refrigeration devices.

[0025] 3. The present invention provides a novel cocoon storage device that utilizes an electric push rod and an electromagnetic chuck to perform multiple samplings in a short period of time. Attached Figure Description

A horizontally placed turntable 2 is installed inside each refrigerated cabinet 1. The turntable 2 is connected to a motor 4 via a lower rotating shaft 3. The motor 4 is installed at the bottom of the refrigerated cabinet 1. A horizontally placed support plate 6, which serves as a filter plate, is positioned below the turntable 2 and is fixedly connected to the inner wall of the refrigerated cabinet 1. The turntable 2 is placed on the support plate 6, and the upper end of the rotating shaft 3 passes through the support plate 6 and is fixedly connected to the bottom of the turntable 2. The rotating shaft 3 is rotatably connected to the support plate 6. Multiple grooves 5 are provided on the top surface of the turntable 2, and a refrigerated box is placed within each groove 5. 7. Multiple ventilation holes are evenly distributed on the walls of the refrigerator box 7. An iron block 8 is installed on the top of the refrigerator box 7. A through hole 9 is opened on the top of the air conditioner 1, located above a groove 5 on the edge of the turntable 2. A bracket 10 is installed on the top of the air conditioner 1, and a vertically mounted electric push rod 11 is installed on the bracket 10. A horizontally placed electromagnetic chuck 12 is installed at the bottom of the electric push rod 11, located above the through hole 9, through which the electromagnetic chuck 12 passes. Pushed by the electric push rod 11, the electromagnetic chuck 12 passes downward through the through hole 9 and connects to the refrigerator box 7 below the through hole 9. The refrigerator box 7 is attached to the electromagnetic chuck 12 by the iron block 8 on top. A temperature and humidity sensor 16 is installed inside each air conditioner 1. A rolling bearing connects the rotating shaft 3 and the support plate 6, and the rotating shaft 3 and the support plate 6 are rotatably connected by the rolling bearing. The internal temperature of the air conditioner 1 is 4-8℃, and the relative humidity is 60-70%. The bracket 10 is detachably connected to the air-conditioned cabinet 1 by screws.

[0035] In this invention, the refrigerated cabinet provides a low-temperature environment for storing silkworm cocoons. A support plate supports a turntable, which rotates in place under the drive of a motor. Grooves on the turntable are used to place refrigerated boxes. These boxes, equipped with ventilation holes, are used to hold the silkworm cocoons requiring refrigeration; the ventilation holes are essential to prevent the silkworm pupae inside from dying due to lack of oxygen. An iron block is used to attach the cocoons to an electromagnetic chuck. The lifting and lowering of the electromagnetic chuck is controlled by an electric push rod. The refrigerated box is attached to the electromagnetic chuck by the iron block. Under the action of the electric push rod, the electromagnetic chuck rises, allowing the refrigerated box to be removed from the through-hole at the top of the refrigerated cabinet, completing the sampling process. This process eliminates the need for manual sampling, saving time and effort. The electric push rod is electrically driven, allowing for rapid ascent and descent, significantly increasing sampling speed compared to manual sampling. After sampling, the through-hole is covered with a cover plate or similar structure to prevent external environmental influence from affecting the internal environment of the refrigerated cabinet. After one sampling, the turntable is rotated to position other refrigerated boxes below the through-hole, allowing for secondary sampling using an electromagnetic chuck. The more samples collected, the more accurate the assessment of changes in the silkworm cocoons. However, excessive sampling is not recommended, as the collected samples cannot be refrigerated again, and excessive sampling reduces the storage capacity of the silkworm cocoons. The refrigerated boxes used to hold the silkworm cocoons in this invention are small in size, thus the electromagnetic chucks used are also small in size, resulting in a naturally small through-hole diameter. During sampling, the external environment has virtually no impact on the internal environment of the refrigerated cabinet in a short period of time.

[0036] The method of using this invention is as follows: Silkworm cocoons are evenly spread inside a refrigerated box, which is then placed in the corresponding grooves of a turntable. Each refrigerated box corresponds to one groove. Initially, the electromagnetic chuck is positioned above the refrigerated cabinet, and the through-hole at the top of the cabinet is blocked. After a period of refrigeration, the through-hole at the top of the cabinet is opened, and the electric push rod is activated to allow the electromagnetic chuck to enter the refrigerated cabinet through the through-hole. The electromagnetic chuck moves downwards to a refrigerated box within the refrigerated cabinet. Subsequently, the electric push rod shortens in the reverse direction and then upwards, lifting the electromagnetic chuck and the refrigerated box onto it from the refrigerated cabinet, completing the sampling. After sampling, the through-hole is then blocked. If a second sampling is required, the turntable is rotated to move other refrigerated boxes below the through-hole, facilitating a second sampling. During storage, the turntable can be rotated periodically to change the position of the refrigerated boxes, preventing them from remaining in the same position for extended periods and ensuring the silkworm cocoons are evenly heated within the refrigerated cabinet.

[0038] Based on Embodiment 1, a cover plate 13 sealing the through hole 9 is installed on the top of the air-conditioned cabinet 1. The cover plate 13 is placed on the top surface of the air-conditioned cabinet 1 and slidably connected to the air-conditioned cabinet 1. A horizontal hydraulic cylinder 14 is installed on one side of the cover plate 13. The telescopic shaft of the horizontal hydraulic cylinder 14 is connected and fixed to the top of the cover plate 13 through a vertically placed short shaft 15. Under the action of the horizontal hydraulic cylinder 14, the cover plate 13 makes linear reciprocating motion on the top surface of the air-conditioned cabinet 1. The cover plate 13 is a circular plate, and the diameter of the cover plate 13 is larger than the diameter of the through hole 9.

[0039] This invention features a cover plate for sealing through holes. A horizontal hydraulic cylinder performs a lateral telescopic movement, causing the cover plate to reciprocate linearly in the horizontal direction.
