Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, specifically relating to a tray for a vacuum freeze dryer. Background Technology

[0002] Vacuum freeze dryers are a type of drying equipment used in modern society. They utilize their excellent freezing effect to cool materials, causing the moisture within the material to move to the surface and freeze. Then, in a vacuum environment, the moisture evaporates through sublimation, reducing the moisture content of the material. Currently, vacuum freeze dryers typically involve placing the material to be freeze-dried on a tray, and then placing the tray inside the vacuum freeze dryer for processing.

[0003] The existing patent with publication number CN220771633U discloses a tray for a vacuum freeze dryer, including a tray body, several protrusions fixedly provided on the inner surface of the tray body, a feeding door installed at the front end of the tray body, and two hinges fixedly provided between the feeding door and the tray body; both sides of the front end face of the feeding door are provided with fixing components corresponding to the tray body.

[0004] The applicant believes that the above solution has the following problems: during the material unloading process, the limiting component on the unloading door needs to be released first. After the limiting component on the unloading door is released, the plate needs to be tilted to pour out the material, which increases the labor intensity of the staff and is time-consuming and labor-intensive. Utility Model Content

[0005] To address the problems existing in the background art, this utility model provides a tray for a vacuum freeze dryer.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A tray for a vacuum freeze dryer includes a material plate mounted inside the tray. First sliders are rotatably mounted on both sides of the material plate, and first grooves are formed on the inner walls of both sides of the tray. Two first sliders correspond one-to-one with two first grooves, and the first sliders and corresponding first grooves are in a limiting sliding engagement. A first spring is fixedly mounted in each first groove, with one end of each first spring fixedly connected to the end of the corresponding first slider away from the discharge gate, and the other end of each first spring fixedly connected to the side wall of the corresponding first groove. Second sliders are fixedly mounted on both sides of the material plate, and second grooves are formed on the inner walls of both sides of the tray. Two second sliders correspond one-to-one with two second grooves, and the second sliders and corresponding second grooves are in a limiting sliding engagement. The second sliders are hemispherical, and the second grooves are arc-shaped.

[0008] Furthermore, several protrusions are provided on the top of the material plate, and a U-shaped baffle is fixedly provided on the top of the material plate along its outer contour.

[0009] Furthermore, one port of the second chute faces the bottom of the disc body, and the other port faces the discharge gate; and the port of each second chute facing the discharge gate is higher than its port facing the bottom of the disc body.

[0010] Furthermore, the limiting component includes limiting blocks, and two third sliding grooves are opened on the feeding gate. A limiting block is slidably arranged in each third sliding groove, and a second spring is fixedly arranged in each third sliding groove. The number of second springs is equal to that of the limiting blocks and they correspond one-to-one. One end of each second spring is fixedly connected to the corresponding limiting block, and the other end is fixedly connected to the feeding gate. Insertion holes are opened on both sides of the inner wall of the disc body. Two insertion holes correspond one-to-one with two third sliding grooves and the insertion holes are connected to the corresponding third sliding grooves. Two limiting blocks correspond one-to-one with two insertion holes, and each limiting block passes through the corresponding third sliding groove and is inserted into the corresponding insertion hole.

[0011] This application has the following beneficial effects:

[0012] 1. During the process of releasing the restriction on the feeding gate, the material plate will automatically tilt due to the elasticity of the first spring, thereby creating a height difference to facilitate the discharge of the processed material. The entire feeding process does not require tilting the material plate separately, saving time and effort and making it highly practical.

[0013] 2. During the process of releasing the restriction on the discharge gate, the material plate will slide towards the discharge gate. At the same time, a portion of the material plate will slide outside the tray, thus preventing material from slipping into the tray during discharge and facilitating material collection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: a tray for a vacuum freeze dryer, including a tray body 1, a feeding door 2 rotatably arranged on one side of the tray body 1, and several hinges (not shown in the figure) fixedly arranged between the bottom of the feeding door 2 and the tray body 1.

[0024] Limiting components are provided at both ends of the top of the feeding gate 2.

[0025] Each limiting component includes a limiting block 11. Two third sliding grooves 10 are symmetrically formed on the unloading gate 2, and a limiting block 11 is slidably installed within each third sliding groove 10. Insertion holes 13 are formed on the inner walls of both sides of the disc body 1. The two insertion holes 13 correspond one-to-one with the two third sliding grooves 10 and are connected to their respective third sliding grooves 10. The limiting block 11 consists of two mutually perpendicular plates. One plate is parallel to the groove direction of the third sliding groove 10, and the other plate is perpendicular to the groove direction of the third sliding groove 10. Each limiting block 11 with a plate parallel to the groove direction of the third sliding groove 10 is slidably installed within its corresponding third sliding groove 10 and engages with its corresponding insertion hole 13.

[0026] Each third slide 10 is provided with a second spring 7, and each second spring 7 is arranged along the sliding direction of the limiting block 11 in the third slide 10. One end of each second spring 7 is fixedly connected to the plate of the limiting block 11 in the third slide 10 perpendicular to the groove direction of the third slide 10, and the other end of each second spring 7 is fixedly connected to the unloading gate 2.

[0027] The length of the partition plate parallel to the third slide groove 10 along the groove direction of the third slide groove 10 is greater than the length of the third slide groove 10 along its own groove direction. This is to prevent the limit block 11 from disengaging from the third slide groove 10 when the second spring 7 is compressed. The partition plate perpendicular to the groove direction of the third slide groove 10 is not only used to push the partition plate parallel to the limit block 11 to slide, but also to prevent the limit block 11 from disengaging from the third slide groove 10.

[0028] A material plate 3 is horizontally mounted inside the disc body 1, and several protrusions 4 are fixedly installed on the top of the material plate 3. A U-shaped baffle is fixedly installed on the top of the material plate 3 along its outer contour, and the U-shaped baffle slides against the inner wall of the disc body 1 to prevent the material on the top of the material plate 3 from sliding into the disc body 1. First sliders 8 are rotatably installed on both sides of the material plate 3, and first grooves 5 are opened on the inner walls of both sides of the disc body 1. Two first sliders 8 correspond one-to-one with two first grooves 5, and the first sliders 8 and the corresponding first grooves 5 are in a limited sliding fit. A first spring 9 is fixedly installed in each first groove 5, and each first spring 9 is arranged along the sliding direction of the first slider 8 in the first groove 5. One end of each first spring 9 is fixedly connected to the end of the corresponding first slider 8 away from the discharge gate 2, and the other end of each first spring 9 is fixedly connected to the side wall of the corresponding first groove 5.

[0029] A second slider 12, hemispherical in shape, is fixedly installed on both sides of the material plate 3. A second groove 6, arc-shaped and adapted to the second slider 12, is formed on the inner wall of both sides of the disc body 1. The two second sliders 12 correspond one-to-one with the two second grooves 6, and there is a limiting sliding fit between the second slider 12 and the corresponding second groove 6. One port of each second groove 6 faces the bottom of the disc body 1, and the other port faces the discharge gate 2. Furthermore, the port of each second groove 6 facing the discharge gate 2 is higher than its port facing the bottom of the disc body 1. When both second sliders 12 are located at the ports of the corresponding second grooves 6 facing the bottom of the disc body 1, the material plate 3 is in a horizontal state. This facilitates the tilting of the material plate 3 towards the bottom of the discharge gate 2 along the guide of the second grooves 6 during sliding, accelerating the overall material discharge.

[0030] Working principle: When material needs to be fed, the limiting block 11 is pushed to slide away from the disc body 1 in the third slide groove 10. During this process, the limiting block 11 gradually compresses the second spring 7, causing the second spring to deform. When the limiting block 11 leaves the corresponding insertion hole 13, the feeding gate 2 releases its restriction on the disc body 1.

[0031] The discharge gate 2 is controlled to rotate, causing the discharge gate 2 to separate from the material plate 3. When the two separate, the second spring 7 returns to its original deformation.

[0032] When the material gate 2 disengages from the material plate 3, the first spring 9, under its own elasticity, pushes the first slider 8 to slide towards the material gate 2 within the second slide groove 6, thereby causing the material plate 3 to slide. The sliding of the material plate 3 causes the second slider 12 to slide along the groove of the second slide groove 6. The second slide groove 6, through the second slider 12, causes the material plate 3 to rotate during the sliding process, thus automatically tilting the material plate 3. Simultaneously, a portion of the material plate 3 slides out of the disc body 1, facilitating material unloading.

[0033] When material needs to be fed, push the material plate 3. This causes the first slider 8 to slide away from the discharge gate 2 within the first slide groove 5. During this process, the first slider 8 will continuously compress the first spring 9. At the same time, the second slider 12 will slide within the second slide groove 6, causing the material plate 3 to rotate and gradually reach a horizontal state.

[0034] When the material plate 3 retracts into the disc body 1, the limiting block 11 is first pushed to slide completely into the third slide groove 10, compressing the second spring 7. Then, the feeding gate 2 is rotated, causing the limiting block 11 to slide back into the insertion hole 13 under the elastic action of the second spring 7, thereby limiting the material plate 3. Furthermore, the feeding gate 2, after being limited, will limit and abut against the material plate 3 through the first spring 9, thereby preventing the material plate 3 from rotating.
