Description

Technical Field

[0001] The utility model relates to the technical field of tray sterilization, in particular to a sterilization device for a cordyceps sinensis cultivation tray. Background Technique

[0002] The cordyceps sinensis cultivation tray is a device for cultivating cordyceps. There are multiple partition plates fixed in the cordyceps cultivation tray. The partition plates are used to divide the cordyceps tray into multiple independent small compartments. People cultivate cordyceps in the small compartments. After the cordyceps cultivation is completed, the tray needs to be cleaned, disinfected and sterilized to ensure the repeated use of the cultivation tray.

[0003] High-pressure steam sterilization is a commonly used sterilization method at present. Generally, the items are wrapped with paper and then placed in a sterilizer for sterilization. A Chinese patent with the publication number CN214969402U discloses a petri dish sterilization device, which can also be used to sterilize the cordyceps cultivation tray. By setting multiple petri dish placement racks, the petri dishes can be separated, the petri dishes are evenly heated, and the number of petri dishes placed can be selected according to needs, which is flexible and convenient; by designing an arc-shaped convex part and a spherical telescopic structure on the petri dish placement rack, the petri dish can be fixed conveniently, preventing the petri dish from falling off, and the picking and placing are relatively safe.

[0004] However, the above patent still has some defects: the positions of two adjacent placement racks cannot be adjusted. Since the cultivation tray is generally box-shaped and has a certain length, width and height, if the height of the placement rack cannot be adjusted, it may be inconvenient to place the cultivation tray; in addition, the above patent cannot press the wrapped paper tightly. Once the wrapped paper loosens during the sterilization process and the packaging of the tray is not tight, it may affect the sterilization effect. Summary of the Utility Model

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 - Figure 3, which is a sterilization device for Cordyceps sinensis cultivation trays provided by an embodiment of the present application, includes a sterilization box 1 and a placement rack installed in the sterilization box 1. The placement rack includes four upright columns 21 symmetrically installed in the sterilization box 1. A support plate 22, a fixed pressure plate 23, and a plurality of partition plates 24 are slidably connected to the upright columns 21, and the plurality of partition plates 24 are all located between the support plate 22 and the fixed pressure plate 23. A plurality of clamping columns 25 are fixedly connected to the top of the support plate 22, the bottom of the fixed pressure plate 23, and the top and bottom of the partition plates 24; Springs 26 are installed between two adjacent partition plates 24, between the partition plates 24 and the fixed pressure plate 23, and between the support plate 22 and the partition plates 24, and the springs 26 are coaxially sleeved outside the upright columns 21; A regulation device for driving the support plate 22 and the fixed pressure plate 23 to approach or move away from each other is installed in the sterilization box 1, and the position heights of the support plate 22 and the fixed pressure plate 23 are also maintained by the regulation device.

[0024] The following is a further introduction in combination with a specific usage scenario. When performing the sterilization work on the cultivation tray 6, first open the door 11 of the sterilization box 1, and then control the support plate 22 and the fixed pressure plate 23 to move away from each other through the regulation device. At this time, all the springs 26 will be stretched synchronously. Then, under the pulling force of the springs 26, the positions of all the partition plates 24 are adjusted, so that the distance between two adjacent partition plates 24, the distance between the partition plates 24 and the support plate 22, and the distance between the partition plates 24 and the fixed pressure plate 23 become larger, which is convenient for the staff to place the tray 6 on the support plate 22 and the partition plates 24. After the tray 6 is placed well, control the support plate 22 and the fixed pressure plate 23 to approach each other. During the approaching process of the support plate 22 and the fixed pressure plate 23, all the springs 26 will gradually return from the stretched state to the normal state until finally to the compressed state, thereby driving all the partition plates 24 to move, so as to realize the clamping of the tray 6. It should be noted here that the position of the partition plate 24 is maintained by the pulling force or elastic force of the spring 26. Since there are four upright columns 21 and they are symmetrically distributed, the springs 26 on the partition plates 24 are relatively evenly and symmetrically distributed. Therefore, the overall force on the partition plates 24 is relatively evenly and stably distributed, which ensures the stability of the support and clamping of the tray.

[0025] In addition, the function of the clamping columns is that when placing the tray 6, it is mainly placed on the clamping columns 25 on the partition plates 24 or the support plate 22, and the tray 6 is supported by the plurality of clamping columns 25. Similarly, when controlling the support plate 22 and the fixed pressure plate 23 to approach and thus press the top surface of each layer of the tray 6, the top surface of the tray 6 is also pressed by the clamping columns 25. Therefore, both the top and bottom surfaces of the tray 6 are fixed at multiple points by the plurality of clamping columns 25. The advantage of this is that it can increase the contact area between the tray 6 and the steam, thereby improving the sterilization efficiency.

[0026] Overall, the position of the support plate 22 and the fixed pressure plate 23 is adjusted by the control device, and then the spring 26 drives the adjustment of multiple partition plates 24. In this way, when placing the sleeve plate 6, the distances between the partition plate 24 and the support plate 22, between the partition plate 24 and the fixed pressure plate 23, and between two adjacent partition plates 24 can be enlarged, which facilitates the placement of the sleeve plate 6. After the sleeve plate 6 is placed, the control device is used to gradually reduce the distances between the partition plate 24 and the support plate 22, between the partition plate 24 and the fixed pressure plate 23, and between two adjacent partition plates 24 to clamp the sleeve plate 6, thereby ensuring that the wrapping paper on the sleeve plate 6 will not become loose during the sterilization process and improving the sterilization effect. In addition, both the upper and lower surfaces of the sleeve plate 6 are multi-point clamped by multiple clamping columns 25, which not only has a good clamping effect but also can increase the contact area between the sleeve plate 6 and the steam, thereby improving the sterilization efficiency. This application can expand the distance between two adjacent partition plates 24, facilitating the placement of the sleeve plate 6, and can quickly and stably press the paper of the sleeve plate 6, improving the convenience of placing and fixing the sleeve plate 6 during the sterilization process and ensuring that the sterilization effect will not be affected.

[0027] Further, referring to Figure 1 - Figure 3 Between two adjacent partition plates 24, between the partition plate 24 and the fixed pressure plate 23, and between the support plate 22 and the partition plate 24, telescopic sleeves 4 are installed, and the spring 26 is located inside the telescopic sleeve 4.

[0028] Combined with the specific use scenario, first, the telescopic sleeve 4 can completely cover the spring 26 so that the spring 26 is not exposed outside, thereby preventing the skin of the staff from being clamped by the spring 26 when taking and placing the sleeve plate 6. In addition, the telescopic sleeve 4 can also limit the distances between two adjacent partition plates 24, between the partition plate 24 and the support plate 22, and between the partition plate 24 and the fixed pressure plate 23, ensuring that the spring 26 will not be stretched too long beyond the elastic limit of the spring 26 during adjustment, which affects the normal use of the spring 26. Moreover, the use of the telescopic sleeve 4 can also improve the support stability of the partition plate 24 to a certain extent.

[0029] Referring to Figure 2 Or Figure 3 As a specific implementation manner of the embodiment of the present application, the control device includes a bidirectional lead screw 31 rotatably connected to the sterilization box 1 and a driving mechanism 32 for driving the bidirectional lead screw 31 to rotate. The support plate 22 and the fixed pressure plate 23 are respectively threadedly connected to the thread portions with different rotation directions of the bidirectional lead screw 31.

[0030] Combined with a specific usage scenario, the driving mechanism 32 drives the bidirectional lead screw 31 to rotate, thereby driving the support plate 22 and the fixed pressure plate 23 to approach or move away from each other, so that the distances between the partition plate 24 and the partition plate 24, the support plate 22 and the fixed pressure plate 23 can be adjusted, facilitating the placement and pressing of the breeding tray 6. In addition, using the bidirectional lead screw 31 for distance adjustment can also ensure the uniformity and stability of the lifting speed of the support plate 22 or the fixed pressure plate 23 during the adjustment process.

[0031] Referring to Figure 2 , as a specific implementation manner of the embodiment of the present application, there are two bidirectional lead screws 31, and the two bidirectional lead screws 31 are symmetrically distributed with respect to the support plate 22.

[0032] Combined with a specific usage scenario, by adopting two bidirectional lead screws 31, and the two bidirectional lead screws 31 are symmetrically distributed with respect to the support plate 22, so that when adjusting, the force to drive the support plate 22 and the fixed pressure plate 23 to lift can be provided simultaneously from both sides of the support plate 22 and the fixed pressure plate 23, thereby ensuring more stable height adjustment of the fixed pressure plate 23 and the support plate 22. In addition, the supporting force at the positions of the support plate 22 and the fixed pressure plate 23 is provided by the force between the meshing surfaces of the support plate 22 and the fixed pressure plate 23 and the screw teeth of the bidirectional lead screw 31. By adopting two bidirectional lead screws 31 and the two bidirectional lead screws 31 being symmetrically distributed with respect to the support plate 22, the stability of the positions of the support plate 22 and the fixed pressure plate 23 after adjustment can also be improved.

[0033] Referring to Figure 3 , as a specific implementation manner of the embodiment of the present application, the driving mechanism 32 includes a transmission rod 321 rotatably connected to the sterilization box 1. An active bevel gear 322 is fixedly connected to each end of the transmission rod 321. A driven bevel gear 323 meshing with the active bevel gear 322 is fixedly connected to the shaft end of the bidirectional lead screw 31. A worm gear 324 is coaxially fixedly connected to the transmission rod 321. A driving rod 326 is rotatably connected in the sterilization box 1. A worm 325 meshing with the worm gear 324 is fixedly connected to the driving rod 326.

[0034] Combined with a specific usage scenario, during adjustment, by rotating the driving rod 326, the transmission rod 321 is controlled to rotate under the transmission of the worm gear 324 and the worm 325. Further, the bidirectional lead screw 31 is driven to rotate under the meshing of the active bevel gear 322 and the driven bevel gear 323. In this way, only by controlling the driving rod 326 can the two bidirectional lead screws 31 be adjusted synchronously. In addition, the cooperation of the worm gear 324 and the worm 325 has self-locking property, which can further ensure the position stability of the partition plate 24, the support plate 22, and the fixed pressure plate 23 after adjustment.

[0035] As a specific implementation manner of the embodiment of the present application, the tooth number ratio of the active bevel gear 322 to the driven bevel gear 323 is greater than 1.

[0036] In combination with a specific usage scenario, the tooth number ratio of the driving bevel gear 322 and the driven bevel gear 323 is greater than 1, thus forming an accelerating gear set, which can make the overall adjustment rate of the support plate 22, the fixed pressure plate 23 and the partition plate 24 faster.

[0037] Refer to Figure 1 and Figure 2 As a specific implementation manner of the embodiment of the present application, one end of the driving rod 326 extends out of the sterilization chamber 1, and a regulating handwheel 327 is fixedly connected to the end of the driving rod 326 extending out of the sterilization chamber 1.

[0038] In combination with a specific usage scenario, during adjustment, by rotating the regulating handwheel 327, the forward and reverse rotation of the driving rod 326 is controlled, and then the overall placement rack is adjusted.

[0039] Furthermore, a motor can also be installed in the sterilization chamber 1 to provide the power for the rotation of the driving rod 326.

[0040] Refer to Figure 1 or Figure 2 or Figure 3 As a specific implementation manner of the embodiment of the present application, uniform ventilation holes 5 are provided on the support plate 22, the fixed pressure plate 23 and the partition plate 24.

[0041] In combination with a specific usage scenario, the uniform ventilation holes 5 on the connecting plate facilitate the circulation of steam in the sterilization chamber 1, thereby increasing the rate of steam diffusion in the sterilization chamber 1, and further improving the sterilization efficiency of the sleeve tray 6.

[0042] As a specific implementation manner of the embodiment of the present application, a high-temperature resistant rubber pad is fixedly connected to the end of the clamping column 25 close to the sleeve tray 6.

[0043] In combination with a specific usage scenario, the high-temperature resistant rubber pad can not only increase the friction coefficient between the pressing column and the packaging paper, which is equivalent to increasing the friction force between the pressing column and the sleeve tray 6, ensuring that the placement of the sleeve tray 6 is more stable, but also making the paper pressing effect better and not prone to loosening; in addition, the high-temperature resistant rubber pad can also reduce the degree of extrusion on the surface of the sleeve tray 6, ensuring that the surface of the sleeve tray 6 is not prone to indentation.

[0044] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
