Description

Technical Field

[0001] The utility model relates to the technical field of freeze-drying devices, and specifically relates to a freeze-drying device for plant extracts. Background Technique

[0002] After the plant is extracted, its extract needs to be freeze-dried to facilitate storage and subsequent transportation. Since the plant extract is generally in a solution state, it needs to be placed in a container and then freeze-dried using a freeze-drying device.

[0003] When the existing freeze-drying device freeze-dries plant extracts, there is a lack of limitation on the container containing the extract. Therefore, it is easy to cause splashing during the placement process, resulting in great waste. And after the container finishes freeze-drying the extract, it is easy to adhere to the freeze-drying tray and is not easy to take out, thus increasing the workload of the freeze-drying process.

[0004] In the patent document with the publication number of CN220771632U, a freeze-drying device for plant extracts is disclosed. There is a tray in the plant extraction box. When the freeze-drying is over, the lever can be pulled upward so that the tray drives the plant extract placement box to slide out of the plant extraction box, which is convenient for workers to take and greatly improves the work efficiency.

[0005] However, since the support area of the plant extract placement box of this freeze-drying device for plant extracts is relatively large, it is difficult to take out the plant extract placement box and the bottom of the support surface after being frozen. Therefore, a freeze-drying device for plant extracts needs to be proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a freeze-drying device for plant extracts to solve the problems of limitation and extraction during the freeze-drying of plant extracts proposed in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A freeze-drying device for plant extracts, including a plant extraction box and a movable support plate arranged inside the plant extraction box. An extraction mechanism is arranged inside the plant extraction box, and a limiting mechanism is arranged on the top of the movable support plate;

[0008] The extraction mechanism includes a clamping block, a side telescopic rod, a side spring, a clamping plate, a pull rod, a handle, a limiting column and a bottom spring. The clamping block is fixedly connected to one side of the movable support plate. The side telescopic rod is fixedly connected to the inner wall of the plant extraction box. The side spring is movably connected to the outside of the side telescopic rod. The clamping plate is fixedly connected to one side of the side telescopic rod. The pull rod is fixedly connected to one side of the clamping plate. The handle is fixedly connected to one side of the pull rod. The limiting column is fixedly connected to the bottom of the inner wall of the plant extraction box. The bottom spring is movably connected to the outside of the limiting column.

[0009] Preferably, one side of the clamping block is set as an arc surface, one side of the clamping position plate is provided with a tooth block, and one side of the tooth block is provided with an arc surface that cooperates with the clamping block. The arc surface will assist the laterally moving clamping block to push the clamping position plate laterally, and the clamping position plate will limit the position of the clamping block.

[0010] Preferably, the top of the bottom spring is connected to the bottom of the movable support plate, and the bottom is connected to the bottom inner wall of the plant extraction box. Spring washers are provided at both the upper and lower ends of the bottom spring. The bottom spring gives the movable support plate a force for automatic restoration, and the spring washers can avoid the supporting surface and prevent the bottom spring from shifting.

[0011] Preferably, four through holes that cooperate with the limit posts are formed through one side of the movable support plate, and the limit posts limit the movement of the movable support plate.

[0012] Preferably, the limiting mechanism includes a fixing plate, a limiting telescopic rod, a limiting spring, a limiting plate and a supporting mesh plate. The fixing plate is fixedly connected to the top of the movable support plate. The limiting telescopic rod is fixedly connected to one side of the fixing plate. The limiting spring is movably connected to the outside of the limiting telescopic rod. The limiting plate is fixedly connected to one side of the limiting telescopic rod. The supporting mesh plate is arranged at the middle position on the top of the movable support plate.

[0013] Preferably, an anti-slip rubber strip is arranged on one side of the limiting plate. On the one hand, the anti-slip rubber strip can prevent the plant extract placement box from shifting and sliding during clamping. On the other hand, it can prevent the plant extract placement box from sticking tightly to the limiting plate after freeze-drying.

[0014] Preferably, a box cover is arranged on the top of the plant extraction box.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. For the freeze-drying device for plant extracts, by arranging the limiting mechanism, the plant extract placement box is placed on the top of the supporting mesh plate, and the plant extract placement box is clamped by the limiting plates arranged on both sides, avoiding the spillage of the plant extract placement box during placement and causing waste. The supporting mesh plate supports the plant extract placement box, so that after the extract is freeze-dried, the bottom of the plant extract placement box is not easily adhered to the top of the supporting mesh plate, which is convenient for taking out.

[0017] 2. The freeze-drying device for plant extracts, through the provided removal mechanism, holds the plant extract placement box, then directly presses down the movable support plate. During the downward pressing of the clamping block, the clamping position plate will move horizontally, giving the clamping block enough space to move downward. After pressing down to a suitable position inside the plant extract box, the clamping position plate rebounds and limits the clamping block, completing the placement of the plant extract placement box. When taking out, pull the handle outward, the clamping position plate releases the restriction on the clamping block, and the bottom spring generates a resilience force acting on the bottom of the movable support plate, causing the movable support plate to return to the highest position. At this time, it is convenient to take out the plant extract placement box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A freeze-drying device for plant extracts, comprising a plant extraction box 1 and a movable support plate 2 arranged inside the plant extraction box 1. An extraction mechanism is arranged inside the plant extraction box 1, and a limiting mechanism is arranged on the top of the movable support plate 2;

[0028] The extraction mechanism includes a clamping block 101, a side expansion rod 102, a side spring 103, a clamping plate 104, a pull rod 105, a handle 106, a limiting column 107 and a bottom spring 108. The clamping block 101 is fixedly connected to one side of the movable support plate 2. One side of the clamping block 101 is set as an arc surface. One side of the clamping plate 104 is provided with a toothed block, and one side of the toothed block is provided with an arc surface that cooperates with the clamping block 101. The arc surface will assist the downward-moving clamping block 101 to laterally push the clamping plate 104, and the clamping plate 104 will limit the clamping block 101. The side expansion rod 102 is fixedly connected to the inner wall of the plant extraction box 1. The side spring 103 is movably connected to the outside of the side expansion rod 102. The clamping plate 104 is fixedly connected to one side of the side expansion rod 102. The pull rod 105 is fixedly connected to one side of the clamping plate 104. The handle 106 is fixedly connected to one side of the pull rod 105. The limiting column 107 is fixedly connected to the bottom of the inner wall of the plant extraction box 1. Four through holes that cooperate with the limiting column 107 are formed through one side of the movable support plate 2. The limiting column 107 limits the movement of the movable support plate 2. The bottom spring 108 is movably connected to the outside of the limiting column 107. The top of the bottom spring 108 is connected to the bottom of the movable support plate 2, and the bottom is connected to the bottom of the inner wall of the plant extraction box 1. Spring washers are arranged at both the upper and lower ends of the bottom spring 108. The bottom spring 108 gives the movable support plate 2 a force for automatic recovery, and the spring washers can avoid the supporting surface and prevent the bottom spring 108 from shifting. Press down the movable support plate 2. At this time, one side of the clamping block 101 exerts pressure on one side of the clamping plate 104, and one side of the clamping plate 104 is provided with a toothed block that cooperates with it. During the downward pressing of the clamping block 101, the clamping plate 104 will move horizontally, giving the clamping block 101 enough space to move downward. After pressing down to a suitable position inside the plant extraction box 1, the clamping plate 104 rebounds and limits the clamping block 101. When taking out, pull the handle 106 outward. At this time, the side spring 103 is compressed by the force, and the clamping plate 104 releases the restriction on the clamping block 101. The bottom spring 108 in the compressed state will generate a resilience force acting on the bottom of the movable support plate 2 under the action of its recovery force, so that the movable support plate 2 returns to the highest position, which can facilitate the removal of the plant extract placement box.

[0029] Embodiment Two:

[0030] On the basis of the first embodiment, the limiting mechanism includes a fixed plate 201, a limiting telescopic rod 202, a limiting spring 203, a limiting plate 204 and a supporting mesh plate 205. The fixed plate 201 is fixedly connected to the top of the movable supporting plate 2. The limiting telescopic rod 202 is fixedly connected to one side of the fixed plate 201. The limiting spring 203 is movably connected to the outside of the limiting telescopic rod 202. The limiting plate 204 is fixedly connected to one side of the limiting telescopic rod 202. An anti-slip rubber strip is arranged on one side of the limiting plate 204. On the one hand, the anti-slip rubber strip can prevent the plant extract placement box from shifting and sliding during clamping. On the other hand, it can prevent the plant extract placement box from sticking tightly to the limiting plate 204 after freeze-drying. The supporting mesh plate 205 is arranged at the middle position on the top of the movable supporting plate 2. The plant extract placement box is placed on the top of the supporting mesh plate 205. The limiting plates 204 arranged on both sides clamp the plant extract placement box. The limiting spring 203 will generate a restoring force, acting on one side of the limiting plate 204, so that the limiting plate 204 applies pressure to the plant extract placement box to firmly clamp it, avoiding the spillage of the plant extract placement box during placement. The supporting mesh plate 205 supports the plant extract placement box, so that after freeze-drying the extract, the bottom of the plant extract placement box is not easily adhered to the top of the supporting mesh plate 205.

[0031] A box cover 3 is arranged on the top of the plant extraction box 1.

[0032] Working principle:

[0033] First of all, through the arranged limiting mechanism, the plant extract placement box is placed on the top of the supporting mesh plate 205. The limiting plates 204 arranged on both sides clamp the plant extract placement box. At this time, the limiting spring 203 in the compressed state will generate a restoring force under the action of its own restoring force, acting on one side of the limiting plate 204, so that the limiting plate 204 applies pressure to the plant extract placement box to achieve the effect of firm clamping, avoiding the spillage of the plant extract placement box during placement and causing waste. The supporting mesh plate 205 supports the plant extract placement box, so that after freeze-drying the extract, the bottom of the plant extract placement box is not easily adhered to the top of the supporting mesh plate 205, which is convenient for taking out.

[0034] Further, through the set extraction mechanism, after clamping the plant extract placement box, directly press down the movable support plate 2. At this time, one side of the clamping block 101 applies pressure to one side of the clamping position plate 104, and there is a tooth block on one side of the clamping position plate 104 that cooperates with it. During the downward pressing of the clamping block 101, the clamping position plate 104 will move horizontally, giving the clamping block 101 enough space to move downward. After pressing down to a suitable position inside the plant extraction box 1, the clamping position plate 104 rebounds and limits the clamping block 101, completing the placement of the plant extract placement box. When taking it out, pull the handle 106 outward. At this time, the side spring 103 is compressed by force, and the clamping position plate 104 releases the restriction on the clamping block 101. The bottom spring 108 in the compressed state will generate a restoring force under its restoring force and act on the bottom of the movable support plate 2, causing the movable support plate 2 to return to the highest position. At this time, it is convenient to take out the plant extract placement box.
