Description

Technical Field

[0001] The utility model belongs to the technical field of dry powder fire extinguisher filling, and particularly relates to a processing device for an integrated dry powder fire extinguisher with air extraction and filling functions. Background Art

[0002] In the traditional production process of dry powder fire extinguishers, the filling of dry powder agents is usually carried out by manual loading and unloading and using independent machines for filling. This method not only has low efficiency, but also because the dry powder filling and vacuum pumping are completed on two different machines, the overall working efficiency is not high. Since the dry powder filling and vacuum pumping are completed at two different workstations respectively, this not only increases the space occupied by equipment on the production line, but also limits the flexibility of the production line. In actual operation, the transfer time from one workstation to another has also become an important factor restricting production efficiency. Therefore, the entire production process lacks continuity, resulting in a decline in overall working efficiency.

[0003] A filling system for a fire extinguisher with a patent application number of CN202210275133.4 includes a workbench, a seal, a fixing mechanism arranged on the workbench, and a base mechanism fixed on the workbench. The seal is used to be placed on the fire extinguisher and is used in cooperation with an air extraction pipe and a filling pipe. The fixing mechanism is used to fix the upper end of the fire extinguisher. The base mechanism is used to fix the lower end of the fire extinguisher and change the position of the fire extinguisher. The above device can only process one fire extinguisher at a time, with low working efficiency and high manufacturing cost when applied to the production line. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the prior art, the above device has low working efficiency when filling and extracting air from dry powder fire extinguishers.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is:

[0006] A processing device for an integrated dry powder fire extinguisher with air extraction and filling functions includes a base, a bracket, an air extraction component, a filling component, a conveyor belt, and a turntable; the bracket is installed on the base, the air extraction component is installed on the left side of the bracket, the air extraction component includes a pump and an air extraction pipe, and the pump is communicated with the air extraction pipe; the filling component is installed on the right side of the bracket, the filling component includes a filling pipe and a material tank, the material tank is communicated with the filling pipe, the turntable is further arranged on the bracket, the turntable is connected to a driving motor at the top of the bracket through a connecting rod, and a conveyor belt is correspondingly arranged at the bottom of the turntable.

[0007] Furthermore, multiple filling components and multiple air extraction components are provided. The filling components and the air extraction components are connected to the bracket through a positioning plate, and the positioning plate is welded to both sides of the top of the bracket.

[0008] By adding multiple filling components and air extraction components, more fire extinguisher tanks can be processed at the same time, significantly improving the overall production capacity of the production line. Although multiple components are added, through a well-designed layout and the use of positioning plates, it is ensured that the entire device remains compact, saving valuable production space. This modular design enables future capacity increases to be achieved by simply adding more filling components and air extraction components without major modifications to the existing production line. The use of positioning plates strengthens the connection between components, improves the stability of the entire device, and reduces problems caused by vibrations or other factors. The design of the positioning plates makes it easier to disassemble and install components when maintenance or component replacement is required, reducing maintenance costs and downtime. By adding multiple components, the filling and air extraction ratios can be flexibly adjusted according to production requirements to adapt to different specifications of fire extinguisher tanks.

[0009] Furthermore, positioning notches are provided on the turntable. A plurality of positioning notches are provided, and the positioning notches are adapted to the bottom diameter of the dry powder fire extinguisher. A separator plate is provided between the bottom of the turntable and the conveyor belt, and a material discharge opening is provided on the separator plate to align the conveyor belt with the positioning notches.

[0010] The design of the positioning notches ensures the stable placement of the fire extinguisher tanks on the turntable, reducing the risk of tilting or falling of the tanks during movement. The design of the separator plate and the material discharge opening ensures that the fire extinguisher tanks can proceed orderly throughout the process from air extraction to filling and then to the conveyor belt, avoiding chaotic placement of the tanks. Through the precise matching of the positioning notches and the material discharge opening, the fire extinguisher tanks can be quickly and accurately transferred from one station to another, improving production efficiency. This design reduces the need for manual intervention, making the entire filling and air extraction process more automated, reducing the operation difficulty and the possibility of errors. The design of the separator plate reduces noise and dust flying during the movement of the tanks, improving the working environment.

[0011] Furthermore, a transmission wheel is provided at the center of the turntable, and the transmission wheel is welded to the connecting rod.

[0012] By setting a transmission wheel in the center of the turntable and welding it to the connecting rod, the connection strength between the turntable and the driving motor is enhanced, ensuring the stability of the turntable during rotation. The design of the transmission wheel ensures that the turntable can accurately align with the positioning notch and the material discharging port during rotation, improving the accuracy of the transfer of the fire extinguisher tank body between different workstations. The design of the transmission wheel reduces the friction between the turntable and the driving mechanism during rotation, reduces wear, and extends the service life of the equipment. The stable rotation of the turntable and the accurate alignment ensure the efficient flow of the fire extinguisher tank body between various workstations, improving production efficiency. Since the design of the transmission wheel enhances the connection stability and reduces the occurrence of equipment failures, the maintenance cost is reduced.

[0013] Further, connection ports are provided at the bottoms of both the air extraction pipe and the filling pipe.

[0014] By providing the connection ports, the air extraction pipe and the filling pipe can be directly connected to the inside of the fire extinguisher tank body without additional connection steps, greatly improving the efficiency of the air extraction and filling processes. The design of the connection ports ensures the sealing of the fire extinguisher tank body during the air extraction and filling processes, preventing external air from entering the tank body, thus ensuring the quality of the dry powder. The method of directly connecting to the inside of the fire extinguisher tank body reduces the leakage points and the risk of dry powder or air leakage. The design of the connection ports makes the operation more convenient, reduces the steps of manual intervention, and reduces the operation difficulty. By directly connecting, the air extraction and filling processes can be better controlled to ensure the same treatment for each fire extinguisher tank body, improving the consistency of product quality.

[0015] Further, a control panel is also installed on the bracket, and the control panel is electrically connected to the driving motor and the pump.

[0016] By centrally controlling the rotation of the turntable and the air extraction process through the control panel, the operation process is simplified and the operation convenience is improved. The control panel can preset programs to automatically control the rotation speed and direction of the turntable and the time and vacuum degree of air extraction, achieving high automation and reducing the need for manual intervention. Through the programs preset by the control panel, it can be ensured that each batch of dry powder fire extinguisher tank bodies follow the same process parameters during the air extraction and filling processes, improving the production consistency of the products. Centralized control reduces the errors caused by manual operation and reduces the error rate. The control panel can display key parameters such as the rotation state of the turntable and the vacuum degree, facilitating the operator to monitor the operation state of the equipment in real time, promptly discover and solve problems, and improving the maintenance efficiency.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model integrates the two steps of air extraction and filling in one workstation, significantly improving the production efficiency of dry powder fire extinguishers. The combined use of the turntable and the conveyor belt enables the fire extinguisher tank to smoothly transition between air extraction and filling, reducing the time and labor intensity of manual handling, thereby enhancing the overall production speed.

[0019] 2. The utility model precisely controls the air extraction and filling processes to ensure that each fire extinguisher tank can reach the required vacuum degree and dry powder filling amount, improving the quality consistency of the products. Through the centralized control of the control panel, the consistency of process parameters can be ensured, further guaranteeing the product quality.

[0020] 3. By setting an isolation plate between the turntable and the conveyor belt and opening a material discharge port on the isolation plate, dust flying can be effectively reduced, improving the working environment. The positioning notch design on the turntable ensures the stable placement of the fire extinguisher tank, reducing the noise and vibration during the movement of the tank, and providing more comfortable working conditions for the operators.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further details the utility model in conjunction with the drawings and specific preferred embodiments.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the parts, so it cannot be understood as a limitation to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example and do not limit the protection scope of the present utility model.

[0029] Embodiment 1: An integrated dry powder fire extinguisher processing device for air extraction and filling is used to evacuate and fill dry powder into the fire extinguisher to be processed. Existing fire extinguishers are usually processed by separating air extraction and filling, that is, first evacuating the fire extinguisher to a vacuum state and then transferring the fire extinguisher to the filling device. The two cannot be carried out synchronously, resulting in low processing efficiency. Therefore, in order to improve the efficiency of air extraction and filling of dry powder fire extinguishers, an integrated dry powder fire extinguisher processing device for air extraction and filling is proposed. Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , it can be seen that it includes a bracket 2 that constitutes the main body of the device. A base 1 is installed at the bottom of the bracket 2, an air extraction component 3 and a filling component 4 are installed on the upper part of the bracket 2. A turntable 5 is installed between the base 1 and the bracket 2, and a conveyor belt 6 is installed below the turntable 5. The air extraction component 3 includes a pump 31 and an air extraction pipe 32. The pump 31 is connected to the air extraction pipe 32. The turntable 5 is connected to the drive motor 521 at the top of the bracket 2 through a connecting rod 52;

[0030] During use, first align the opening of the fire extinguisher tank with the air extraction pipe 32 of the air extraction component 3. Under the action of the pump 31, the air in the fire extinguisher tank is extracted until it reaches a vacuum state. Since a sealing cover is provided at the top of the seal, no air will enter during the transfer of the fire extinguisher, affecting the vacuum environment in the tank. After air extraction, the fire extinguisher is transferred to below the filling component 4 under the drive of the turntable 5. The filling pipe 41 is aligned with the tank mouth of the fire extinguisher, and the dry powder in the material tank 42 is sucked into the tank under the action of the fire extinguisher tank, realizing the filling of the fire extinguisher tank. After the dry powder filling is completed, the fire extinguisher is transferred to the conveyor belt 6 under the drive of the turntable 5. Thus, the entire processing of the fire extinguisher is completed. By using the turntable 5 to transfer the fire extinguisher after air extraction to the other side of the device for dry powder filling, the processing efficiency of the dry powder fire extinguisher is greatly improved.

[0031] Embodiment 2: Compared with Embodiment 1, Embodiment 2 can further improve the processing efficiency of the fire extinguisher. Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 andFigure 5 It can be seen that the air extraction component 3 and the filling component 4 are installed on the bracket 2 through the positioning plate 21. The positioning plate 21 is welded to the left and right sides of the top of the bracket. Three pump machines 31 are installed on the positioning plate 21 on the left side of the bracket 2, and the pump machines 31 are all connected to the air extraction pipe 32. A material tank 42 is installed on the positioning plate 21 on the right side of the bracket 2. Three respectively connected filling pipes 41 are arranged below the material tank 42 for filling the fire extinguisher. When extracting air from the fire extinguisher, align the connection port of the air extraction pipe 32 with the mouth of the fire extinguisher tank, and extract the air inside the fire extinguisher. The staff pulls out the air extraction pipe 32 to complete the vacuuming process of the fire extinguisher. The fire extinguisher is placed in the positioning notch 54 of the turntable 5. There are three positioning notches 54, which are respectively aligned with the air extraction pipe 32. After the fire extinguisher is extracted with air, it is positioned in the positioning notch 54 and the turntable 5 is driven to rotate by the driving motor 521. The positioning notch 54 drives the fire extinguisher to rotate under the filling pipe 41. After the dry powder filling is completed, the turntable 5 continues to rotate to send the fire extinguisher into the conveyor belt 6. The device simultaneously extracts air and fills three fire extinguishers, which further improves the working efficiency of the device.

[0032] Embodiment 3: Compared with Embodiment 1 and Embodiment 2, in order to prevent the fire extinguisher from falling to the other side of the conveyor belt 6 during the rotation of the turntable 5 and thus unable to carry out the filling process, a partition plate 53 is provided between the turntable 5 and the conveyor belt 6. The partition plate 53 is fixed on the base 1 and does not contact the conveyor belt 6. A material discharge port 55 is opened on the partition plate 53 above the discharging method of the conveyor belt 6. When the turntable 5 drives the fire extinguisher to transfer, due to the existence of the partition plate 53, the fire extinguisher will not fall onto the conveyor belt 6, ensuring the continuity of air extraction and filling. After the filling is completed, the fire extinguisher rotates to the material discharge port 55 and enters the conveyor belt 6. Under the action of the conveyor belt 6, it leaves the device. The partition plate 53 ensures that the device can continuously complete the air extraction and filling of the fire extinguisher.

[0033] Embodiment 4: The fire extinguisher is transferred under the drive of the turntable 5. Therefore, the turntable 5 needs to rotate stably. Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, it can be seen that the control panel 22 is electrically connected to the drive motor 521 and the pump 31. The control panel 22 has a program for controlling the rotation of the drive motor 521 and the opening and closing of the pump 31, so as to realize the stop and operation of the air extraction work of the pump 31. And by controlling the rotation speed of the drive motor 521, the transmission wheel 51 connected to the center of the turntable 5 through the connecting rod 52 is controlled. The transmission wheel 51 drives the turntable 5 to rotate. The above steps can be achieved by setting a sensor at the connection port of the air extraction pipe 32. The sensor is used to detect whether the air extraction pipe 31 is in contact with the fire extinguisher, and control the pump 31 to start. The pressure in the fire extinguisher is detected by the sensor to control the pump 31 to close. And the weight of the fire extinguisher after filling can be displayed on the control panel through the sensor, so as to detect whether the filling meets the standard. The drive motor 521 is controlled to stop running by the position sensor on the turntable 5, so that the fire extinguisher contacts the conveyor belt 6 and is taken out of the device under the drive of the conveyor belt 6. Thus, the whole process is completed.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
