[0002] Aluminum phosphide tablets are a odorless, hygroscopic, and water-insoluble broad-spectrum fumigant insecticide. In sealed warehouses or containers, they can directly kill various stored grain pests and also kill rats. The production process of aluminum phosphide tablets involves using an extrusion device to compress the raw materials. Patent application number "CN202420274946.6" discloses a high-efficiency aluminum phosphide tablet pressing device for easy discharge, including a base plate and a pressure plate. The top of the base plate is bolted with four symmetrically arranged connecting columns, the tops of which share a common passageway. A worktable is bolted to the top of the worktable, which is bolted to the top of a processing cylinder, a material discharge channel, and a collection box. A motor is mounted on the top of the base plate, and the output end of the motor is fixedly connected to a lead screw via a coupling. With the design of the top plate and top block, after pressing, the motor is turned on, which drives the top plate to push the material out and moves the top block to push the material out into the material discharge channel and then into the collection box, thus achieving the effect of easy material discharge. The above technical solution solves the problems of no material discharge component and poor buffering effect in the prior art.

[0003] The aforementioned patent achieves automatic collection of molded aluminum phosphide tablets through the cooperation of the top plate and the top block. However, the patent only sets up one set of cooperating pressure plate and processing cylinder, which means that the device can only produce one tablet at a time, thus affecting the tablet production efficiency. Moreover, the tablet pushing method can only push individual tablets. Utility Model Content

[0020] Please see Figure 1-5This utility model provides the following technical solution: a pressing device for aluminum phosphide production, including a base 1, a storage box 4, and a telescopic pressure plate 5. A mounting frame 11 is provided on the base 1, and a protective cylinder 12 is mounted on the base 1 via an electric threaded rod. The mounting frame 11 is provided with a storage box 4 and a telescopic pressure plate 5 that cooperate with the protective cylinder 12. It also includes a forming disc 2 and a storage cylinder 3. The forming disc 2 and a fan 13 are respectively provided on the inner and outer walls of the protective cylinder 12. A fan 13 is mounted inside the forming disc 2 via an electric telescopic rod. The top plate 21 is fitted with a groove on the top surface of the disc 2. The pressure plate 51, which is fitted with the forming disc 2, is installed on the bottom plate of the telescopic pressure plate 5 via a spring telescopic rod. The base 1 is provided with a storage cylinder 3 that is connected to the bottom opening of the protective cylinder 12. The storage box 4 is equipped with an electric telescopic plate 41 via an electric telescopic rod. The electric telescopic plate 41 is provided with a feeding pipe 42 that is fitted with the groove on the top surface of the forming disc 2 and the bottom discharge port of the storage box 4. Electric valves 43 are provided at both ends of the feeding pipe 42 and at the bottom discharge port of the storage box 4.

[0021] The base 1 is used to install the remaining components of the device. A controller is installed on the base 1 to control the operation of the electrically powered components of the device. The controller is electrically connected to the electrically powered components. The controller and electric valve 43 are common, mature components and do not need to be described in detail in the instruction manual. The mounting bracket 11 is used to install the storage box 4 and the telescopic pressure plate 5. The storage box 4 contains the raw materials to be extruded. The bottom discharge port of the storage box 4 is used to feed the raw materials stored in the storage box 4 into the feeding pipe 42. The electric valves 43 installed on the bottom discharge port of the storage box 4 and the feeding pipe 42 are used to control whether the bottom discharge port of the storage box 4 and the feeding pipe 42 are connected, and whether the feeding pipe 42 is connected to the outside. The protective cylinder 12 contains a container for holding the materials to be extruded. The device uses a forming disc 2 for raw materials. The top surface of the forming disc 2 has grooves to hold the raw materials. Multiple grooves on the top surface of the forming disc 2 allow the device to produce multiple tablets simultaneously. The feeding pipe 42 is positioned to correspond one-to-one with the grooves on the top surface of the forming disc 2. The positioning of the feeding pipe 42 ensures that the raw materials in the feeding pipe 42 can be fed into each groove on the top surface of the forming disc 2. When the device is in use, the electric valve 43 is released from the bottom discharge port of the storage box 4 and the top of the feeding pipe 42. At this time, the raw materials stored in the storage box 4 fall into the feeding pipe 42. Subsequently, the electric valve 43 seals the feeding pipe 42 and the bottom discharge port of the storage box 4. The distance between the electric valves 43 at both ends of the feeding pipe 42 is fixed, achieving quantitative dispensing of the raw materials. The electric telescopic rod on the electric telescopic plate 41 is installed on the storage box 4. When the device is in use, the electric telescopic rod on the electric telescopic plate 41 is extended. After the feeding pipe 42 enters the top groove of the forming plate 2, the electric valve 43 on the feeding pipe 42 is released from its closure. The raw material in the feeding pipe 42 falls into the top groove of the forming plate 2, realizing the quantitative addition of raw material. The telescopic pressure plate 5 and the pressure plate 51 are used to squeeze the raw material placed in the forming plate 2. The bottom of the pressure plate 51 is provided with a protrusion that matches the top groove of the forming plate 2. During the downward movement of the pressure plate 51, the bottom protrusion of the telescopic pressure plate 5 enters the top groove of the forming plate 2. During the movement of the bottom protrusion of the pressure plate 51, it will compress the forming plate. The raw material in the groove on the top surface of platen 2 is squeezed. During the squeezing process, the spring telescopic rod on the pressure plate 51 is pushed, and the pushed spring telescopic rod plays a buffering role, reducing the damage to the pressure platen 51 and the telescopic pressure plate 5 during the operation of the device. The shape of the electric telescopic plate 41 and the telescopic pressure plate 5 matches the protective cylinder 12. The shape of the bottom plate of the electric telescopic plate 41 and the telescopic pressure plate 5 ensures that the protective cylinder 12 is sealed by the bottom plate of the electric telescopic plate 41 and the telescopic pressure plate 5 during the use of the device, preventing the raw material from drifting into the external environment during the falling and squeezing process, thus ensuring the health of the workers. The top of the top plate 21 is provided with a support rod that penetrates the bottom surface of the groove on the top surface of the forming plate 2. After the tablets are formed,The electric telescopic rod on the top plate 21 extends, and the top support rod of the top plate 21 pushes the formed tablet away from the groove on the top surface of the forming disc 2. The fan 13 on the protective cylinder 12 blows the formed tablet away from the forming disc 2. After the tablet is pushed away from the groove on the top surface of the forming disc 2, the fan 13 is started. The airflow generated by the fan 13 blows the formed tablet away, and the blown tablet falls into the protective cylinder 12. The discharge port at the bottom of the protective cylinder 12 is used to allow the raw material blown away from the forming disc 2 to enter the storage cylinder 3. The storage cylinder 3 is used to collect the raw material. A detachable collection frame is provided on the side wall of cylinder 3. Raw materials entering cylinder 3 will fall into the collection frame. The user can remove the collection frame from cylinder 3 to retrieve the raw materials stored in cylinder 3. The protective cylinder 12 is threadedly mounted on an electric threaded rod. When the electric threaded rod is started, the protective cylinder 12 begins to move under the action of the thread. The storage box 4 and the telescopic pressure plate 5 are both set on the mounting frame 11. The moving protective cylinder 12 realizes the switching between the engagement of the telescopic pressure plate 5 and the protective cylinder 12, and the engagement of the storage box 4 and the telescopic pressure plate 5.

[0022] Specifically, a pressure sensor 24 is provided on the top surface of the top support rod of the top plate 21.

[0023] The pressure sensor 24 is used to detect the pressure on the top support rod of the top plate 21. The controller processes the data obtained by the pressure sensor 24 to determine whether the pressure applied by the telescopic pressure plate 5 to the raw material has reached a suitable value, so that the user can determine whether the raw material has been extruded and formed.

[0024] Specifically, the top of the top support rod of the top plate 21 is provided with a disc protrusion, and the top disc of the top support rod of the top plate 21 matches the groove on the top surface of the forming disc 2.

[0025] The shape of the disc protrusion on the top support rod of the top plate 21 ensures that the bottom surface of the top protrusion of the top plate 21 contacts the bottom surface of the groove on the top surface of the forming plate 2. At this time, the bottom surface of the groove on the top surface of the forming plate 2 plays the role of supporting the disc set on the top support rod of the top plate 21. The disc on the top support rod of the forming plate 2 ensures that the top plate 21 will not be subjected to pressure from the pressure plate 51 during the extrusion of raw materials, thus ensuring the stability of the top plate 21 during the extrusion of raw materials.

[0026] Specifically, the inside of the storage cylinder 3 is provided with downwardly inclined guide plates 31 arranged in an alternating pattern.

[0027] The guide plate 31 on the storage cylinder 3 plays a guiding role. During the process of raw material falling, the raw material will move along the guide plate 31, realizing the gradual falling of tablets. The guide plate 31 can prevent the raw material from falling directly to the bottom of the storage cylinder 3, reducing the damage to the raw material during the falling process.

[0028] Specifically, the inner wall of the storage box 4 is provided with a vibrating rod 44, and the bottom surface of the inner wall of the storage box 4 is a slope that is inclined towards the bottom discharge port of the storage box 4.

[0029] The vibrating rod 44 is used to vibrate the raw materials stored in the storage bin 4. When the device is in use, the vibrating rod 44 is activated. The raw materials vibrated by the vibrating rod 44 play a role in assisting the raw materials to fall, ensuring that the raw materials can fall smoothly into the bottom discharge port of the storage bin 4. The vibrating rod 44 is a common and mature structure and does not need to be described in detail in the instruction manual. The bottom surface shape of the inner wall of the storage bin 4 plays a guiding role, ensuring that the raw materials do not accumulate at the bottom of the inner wall of the storage bin 4.

[0030] Specifically, a feeding groove 23 is provided on the part of the bottom surface of the protective cylinder 12 where the forming plate 2 is not provided, and the feeding groove 23 is inclined toward the bottom opening of the protective cylinder 12.

[0031] The bottom opening of the protective cylinder 12 is positioned corresponding to the top opening of the storage cylinder 3. When the device is in use, the bottom opening of the protective cylinder 12 and the top opening of the storage cylinder 3 are positioned above the top of the uppermost guide plate 31, which reduces the distance the tablets fall before contacting the guide plate 31 and ensures the working effect of the guide plate 31. The shape of the feeding trough 23 ensures that the tablets falling into the protective cylinder 12 can fall smoothly into the bottom opening of the protective cylinder 12, ensuring the tablet collection effect of the storage cylinder 3.

[0032] Specifically, a collection box 14 is provided on the side wall of the protective cylinder 12, a fan 13 is provided on the collection box 14, and a telescopic sealing plate 22 is provided on the bottom opening of the protective cylinder 12.

[0033] During the use of the device, the blower 13 connected to the collection box 14 is started. The blower 13 will draw the raw materials that have not been extruded and formed in the protective cylinder 12 out of the protective cylinder 12, thus cleaning the raw materials in the protective cylinder 12. The collection box 14 is equipped with a filter component for filtering powder in the airflow, thus collecting the raw materials carried in the airflow. The filter component should be selected according to the actual use and does not need to be described in detail in the instruction manual. The telescopic sealing plate 22 set on the bottom opening of the protective cylinder 12 is used to close the bottom opening of the protective cylinder 12, ensuring the cleaning effect of the blower 13 on the raw materials inside the protective cylinder 12.

[0034] The working principle and usage process of this utility model are as follows: The electric threaded rod is activated, and the protective cylinder 12 moves to a position that mates with the storage box 4 under the action of the thread. This releases the seal of the electric valve 43 located at the bottom discharge port of the storage box 4 and the top of the feeding pipe 42, allowing the raw material to fall into the feeding pipe 42. After the raw material is added, the electric valve 43 at the bottom discharge port of the storage box 4 and the top of the feeding pipe 42 seals the bottom discharge port of the storage box 4 and the top of the feeding pipe 42. The electric telescopic rod on the electric telescopic plate 41 is then extended, and the electric telescopic plate 41, carrying the feeding pipe 42, enters the groove on the top surface of the forming disc 2. The electric valve 43 at the bottom of the feeding pipe 42 is then released, allowing the raw material to fall into the groove on the top surface of the forming disc 2. The electric valve 43 and the electric telescopic plate 41 are then closed. The original state is restored, and the protective cylinder 12 is moved to a position that cooperates with the telescopic pressure plate 5. The telescopic pressure plate 5 is extended, and the pressure plate 51 squeezes the raw material in the groove on the top surface of the forming plate 2. After the pressure sensor 24 receives a large pressure, the controller controls the telescopic pressure plate 5 to stop squeezing the raw material. The raw material is formed, and the telescopic pressure plate 5 is moved back to its original position. The electric telescopic rod installed on the top plate 21 is extended, and the top plate 21 pushes the formed tablet away from the groove on the top surface of the forming plate 2. The fan 13, which is not connected to the collection box 14, is started. The tablet falls onto the feeding trough 23 under the action of the airflow. After passing through the bottom opening of the protective cylinder 12 and the top opening of the storage cylinder 3, the tablet falls onto the guide plate 31. The tablet moves along the guide plate 31 and falls into the collection frame set on the storage cylinder 3, thus realizing the collection of the tablet.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
