The rotating disk is connected to the partition via a support assembly, and is fixedly connected to the output end of the servo motor. A plurality of pressure blocks are arranged in a circular array and fixed to the rotating disk on the side away from the servo motor. The support plate is connected to the partition via a plurality of support legs. The vibrating plate is located on the support plate on the side away from the rotating disk. A plurality of transmission rods are arranged in a circular array and fixed to the vibrating plate on the side near the support plate, with the ends of the transmission rods extending outwards through the support plate. The fixing block is fixedly connected to the ends of the transmission rods. The squeezing block is fixed to the fixing block on the side away from the transmission rods. The drying box is connected to the vibrating plate via a sliding assembly. The spring is sleeved on the transmission rod, and both ends of the spring are fixedly connected to the support plate and the fixing block, respectively.
[0006] In a preferred embodiment, the pressure block has a right-angled trapezoidal structure, and the inclination direction of the inclined surface of the pressure block is the same as the rotation direction of the servo motor.
[0007] In a preferred embodiment, the extrusion block has an arc-shaped structure, and the arc-shaped surface of the extrusion block slides in contact with the inclined surface of the pressure block.
[0008] In a preferred embodiment, the thickness of the extrusion block is greater than the thickness of the pressure block.
[0009] In a preferred embodiment, the support assembly includes an annular groove and support rods; the rotating disk has an annular groove on the side near the partition; a plurality of support rods are fixedly arranged in an annular array within the annular groove, and the ends of the support rods pass through the annular groove and are fixedly connected to the partition; wherein, the support rods slide in conjunction with the annular groove.
[0010] In a preferred embodiment, the sliding assembly includes a sliding groove and a sliding block; the shaking plate has a sliding groove on the side near the drying box; the sliding block is fixed to the side of the drying box near the shaking plate; wherein the sliding block slides in conjunction with the sliding groove.
[0011] In a preferred embodiment, the sliding block has a T-shaped structure, and the dimension of the sliding block on the side closer to the drying box is larger than the dimension of the sliding block on the side farther away from the drying box.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are:
[0013] This vacuum drying oven, equipped with a vibration component, operates by opening the door, placing the medicine to be dried in the drying box, closing the door, and starting the main body of the vacuum drying oven. The servo motor's output shaft rotates, causing the rotating disk and the pressure block to rotate. When the pressure block contacts the extrusion block, it compresses the extrusion block, causing the extrusion block, fixed block, and transmission rod to move upwards. This compresses the spring, causing the vibration plate to move the drying box upwards until the extrusion block contacts the top surface of the pressure block. At this point, the spring no longer compresses. The spring contracts, and the shaking plate and drying box move to their highest positions. When the squeezing block and the top surface of the pressure block are no longer in contact, the spring is no longer under force and begins to stretch, causing the squeezing block, the fixed block, and the transmission rod to move downwards. This causes the shaking plate to move the drying box downwards until the squeezing block contacts the rotating disk. At this point, the spring returns to its original shape. This process is repeated, causing the shaking plate to continuously move the drying box up and down, allowing the medicine inside the drying box to be continuously shaken, ensuring that the medicine is fully dried. By shaking the drying box up and down, the medicine inside the drying box is fully dried, greatly improving the drying efficiency of the medicine.
[0014] This vacuum drying oven features a sliding groove and a sliding block. The sliding block engages with the sliding groove, allowing the support plate to be disassembled. This not only facilitates the selection of a suitable drying box based on the size and properties of the drug, but also allows for easier removal of the drug from the drying box after drying. The T-shaped structure of the sliding block not only prevents it from disengaging from the sliding groove but also increases the contact area between the sliding block and the sliding groove, making the connection between them more stable.

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.
[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.
[0030] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.
[0031] Please see Figures 1 to 5 As shown, this embodiment includes a vacuum drying oven body 1, a shaking assembly 2, a support assembly 3, and a sliding assembly 4;
[0032] The vacuum drying oven body 1 includes a box body 101, a door 102, and a partition 103; the door 102 is hinged to the box body 101; the partition 103 is fixed inside the box body 101; the box body 101, the door 102, and the partition 103 constitute a drug drying chamber.
[0033] The shaking assembly 2 is arranged on the partition 103; wherein, the shaking assembly 2 includes a servo motor 201, a rotating disk 202, a pressure block 203, a support plate 204, a shaking plate 205, a transmission rod 206, a fixing block 207, a pressing block 208, a drying box 209, and a spring 210; the servo motor 201 is fixed to the partition 103 by a motor mount, and the output end of the servo motor 201 extends through the partition 103 into the drug drying chamber; the rotating disk 202 is connected to the partition 103 by a support assembly 3, and the rotating disk 202 is fixedly connected to the output end of the servo motor 201; four pressure blocks 203 are arranged in a ring array on the rotating disk 202 away from the servo motor 205. 1. One side; support plate 204 is connected to partition plate 103 via four support legs; vibration plate 205 is located on the side of support plate 204 away from rotating disk 202; four transmission rods 206 are fixed in a ring array on the side of vibration plate 205 near support plate 204, and the ends of transmission rods 206 extend through support plate 204 to the outside; fixing block 207 is fixedly connected to the ends of transmission rods 206; pressing block 208 is fixedly located on the side of fixing block 207 away from transmission rods 206; drying box 209 is connected to vibration plate 205 via sliding assembly 4; spring 210 is sleeved on transmission rod 206, and the two ends of spring 210 are fixedly connected to support plate 204 and fixing block 207 respectively.
[0034] This invention, by incorporating a shaking component 2, allows for the following operation: The chamber door 102 is opened, the medicine to be dried is placed in the drying box 209, the door 102 is closed, and the vacuum drying chamber body 1 is activated to dry the medicine in the drying box 209. The servo motor 201 is then activated, causing its output shaft to rotate, which in turn rotates the rotating disk 202 and the pressure block 203. When the pressure block 203 contacts the squeezing block 208, it compresses the squeezing block 208, causing the squeezing block 208, the fixing block 207, and the transmission rod 206 to move upwards. This causes the spring 210 to contract, and the shaking plate 205 moves the drying box 209 upwards until the squeezing block 208 contacts the top surface of the pressure block 203. At this point, the spring... When spring 210 stops contracting and the shaking plate 205 and drying box 209 move to their highest positions, and the squeezing block 208 no longer contacts the top surface of the pressure block 203, the spring 210 is no longer under force and begins to stretch, causing the squeezing block 208, the fixing block 207, and the transmission rod 206 to move downwards. This causes the shaking plate 205 to drive the drying box 209 downwards until the squeezing block 208 contacts the rotating disk 202. At this point, the spring 210 returns to its original shape. This process is repeated, causing the shaking plate 205 to drive the drying box 209 to move up and down continuously. This allows the medicine inside the drying box 209 to be continuously shaken, ensuring that the medicine is fully dried. By shaking the drying box 209 up and down repeatedly, the medicine inside the drying box 209 is fully dried, greatly improving the drying efficiency of the medicine.
[0035] In a preferred embodiment, the pressure block 203 has a right-angled trapezoidal structure, and the inclination direction of the inclined surface of the pressure block 203 is the same as the rotation direction of the servo motor 201. The extrusion block 208 has an arc-shaped structure, and the arc-shaped surface of the extrusion block 208 slides in contact with the inclined surface of the pressure block 203. This facilitates the inclined surface of the pressure block 203 to press against the arc-shaped surface of the extrusion block 208, allowing the extrusion block 208, the fixed block 207, and the transmission rod 206 to move upward.
[0036] In a preferred embodiment, the thickness of the extrusion block 208 is greater than that of the pressure block 203. This is to prevent the inclined surface of the pressure block 203 from detaching from the curved surface of the extrusion block 208 during the process of the inclined surface of the pressure block 203 extruding the curved surface of the extrusion block 208.
[0037] As a preferred embodiment, the support assembly 3 includes an annular groove 301 and support rods 302; the rotating disk 202 has an annular groove 301 on the side near the partition 103; four support rods 302 are fixedly arranged in an annular array in the annular groove 301, and the ends of the support rods 302 pass through the annular groove 301 and are fixedly connected to the partition 103; wherein, the support rods 302 and the annular groove 301 are in sliding fit.
[0038] This invention improves the stability of the rotating disk 202 during rotation by setting an annular groove 301 and a support rod 302, and by utilizing the sliding fit between the support rod 302 and the annular groove 301.
[0039] As a preferred embodiment, the sliding component 4 includes a sliding groove 401 and a sliding block 402; the shaking plate 205 has a sliding groove 401 on the side near the drying box 209; the sliding block 402 is fixed to the drying box 209 on the side near the shaking plate 205; wherein the sliding block 402 is slidably engaged with the sliding groove 401; wherein the sliding block 402 has a T-shaped structure, and the size of the side of the sliding block 402 near the drying box 209 is larger than the size of the side of the sliding block 402 away from the drying box 209; the bottom surface of the fixed block 207 is higher than the top surface of the pressure block 203.
[0040] This invention, by setting a sliding groove 401 and a sliding block 402, utilizes the sliding engagement of the sliding block 402 with the sliding groove 401 to enable the support plate 204 to be disassembled. This not only facilitates the selection of a suitable drying box 209 according to the size and properties of the drug, but also allows for easier removal of the drug from the drying box 209 after drying. Setting the sliding block 402 into a T-shaped structure not only prevents the sliding block 402 from disengaging from the sliding groove 401, but also increases the contact area between the sliding block 402 and the sliding groove 401, making the connection between the sliding block 402 and the sliding groove 401 more stable.
[0041] The vacuum drying oven body 1 and the servo motor 201 are both conventional instruments. Their working principles, dimensions and models are not related to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0042] Working principle
[0043] In use, the vacuum drying oven is operated as follows: First, the medicine to be dried is placed in the drying box 209. Then, the oven door 102 is opened, and the sliding block 402 is inserted into the sliding groove 401 and slid until its end face contacts the inner wall of the groove 401. At this point, the drying box 209 is fixed in position. Then, the oven door 102 is closed, and the vacuum drying oven body 1 is started to dry the medicine in the drying box 209. Next, the servo motor 201 is started to... When the output shaft 201 rotates, the rotating disk 202 rotates, causing the support rod 302 to slide within the annular groove 301. The rotation of the rotating disk 202 also causes the pressure block 203 to rotate. When the inclined surface of the pressure block 203 contacts the arc-shaped surface of the extrusion block 208, the inclined surface of the pressure block 203 presses against the arc-shaped surface of the extrusion block 208, causing the extrusion block 208, the fixed block 207, and the transmission rod 206 to move upwards. This causes the spring 210 to contract under pressure, and the vibrating plate 205 drives the drying box 209 to move upwards until the extrusion block... When the arc-shaped surface of the pressing block 208 contacts the top surface of the pressure block 203, the spring 210 stops contracting, and the vibrating plate 205 and the drying box 209 move to their highest positions. When the arc-shaped surface of the pressing block 208 no longer contacts the top surface of the pressure block 203, the spring 210 is no longer under force and begins to extend, causing the pressing block 208, the fixing block 207, and the transmission rod 206 to move downwards. This causes the vibrating plate 205 to drive the drying box 209 downwards until the arc-shaped surface of the pressing block 208 contacts the rotating disk 202. At this point, the spring 210 returns to its original shape. This process is repeated, causing the shaking plate 205 to continuously move the drying box 209 up and down, allowing the medicine inside the drying box 209 to be continuously shaken, ensuring that the medicine is fully dried. After the medicine is dried, the servo motor 201 is controlled so that its output shaft stops rotating. Then, the box door 102 is opened, and the drying box 209 is moved so that the sliding block 402 slides in the opposite direction within the sliding groove 401 until the sliding block 402 disengages from the sliding groove 401, at which point the medicine inside the drying box 209 can be removed.
