Description

Technical Field

[0001] The present application relates to the technical field of powder packaging, and in particular to a negative pressure exhaust device of a powder packaging machine. Background Art

[0002] A powder packaging machine is a device equipped with a metering system and packaging and filling components. It can be used to automatically or semi-automatically put powdered materials (such as flour, chemical powder, pharmaceutical powder, etc.) into packaging bags. It is usually used in food, chemical, pharmaceutical and other industries to quickly and efficiently complete product packaging. Usually, the powder packaging machine inserts a vacuum pipe or suction pipe into the packaging bag, and then uses negative pressure to extract the air in the packaging bag, so that the powder in the bag is filled more tightly, improving packaging efficiency and sealing. Extracting the air in the bag can also reduce the volume of the packaging bag, making the packaging more compact, thereby saving storage and transportation space. In order to avoid extracting the already filled powder in the packaging bag together when pumping air, a filter or mesh is generally installed on the vacuum pipe or vacuum head to prevent the powder from entering the pipeline and avoid extracting the powder together to ensure the packaging effect and product quality.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the existing methods prevent the powder from being sucked out together by installing a filter or a mesh on the suction pipe or the suction head. However, in the actual packaging process, the suction head or the suction pipe and other related suction equipment are repeatedly used for suction, and a large amount of powder may remain on the filter or mesh. When a large amount of powder remains, it may cause the mesh or the filter to be blocked, affecting the suction effect and the actual packaging efficiency.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a negative pressure exhaust device for a powder packaging machine. Figure 1-3 A negative pressure exhaust device for a powder packaging machine comprises a packaging frame 1, a storage box 2 is fixedly connected to the top of the packaging frame 1 by bolts, a fixing frame 3 is fixedly connected to one side of the packaging frame 1 by bolts, a vacuum pump 4 is fixedly connected to the top of the fixing frame 3 by bolts, a vacuum pump 4 is provided at one end of the vacuum pump 4, and the vacuum pump 4 is provided with an exhaust member, and the exhaust member is arranged on the top of the fixing frame 3, a sliding groove 7 is opened at the top of the fixing frame 3, a screw rod 11 is rotatably connected to the inner cavity side wall of the sliding groove 7 by a rotating shaft, one end of the screw rod 11 rotates through the sliding groove 7, a driving motor 8 is fixedly connected to one side of the fixing frame 3 by bolts, and the driving motor 8 is fixedly connected to The screw rod 11 passes through one end of the sliding groove 7, and a recovery part is provided on the surface of the screw rod 11, and the recovery part is arranged on one side of the storage box 2. The suction part includes a first telescopic hose 5, a linear actuator 6, a suction head 14 and a filter plate 15. One end of the vacuum pump 4 is fixedly connected to the first telescopic hose 5 through a clamp, and the end of the first telescopic hose 5 away from the vacuum pump 4 is fixedly connected to the suction head 14 through a clamp. The inner cavity side wall of the suction head 14 is fixedly connected to the filter plate 15 through bolts, and the surface of the suction head 14 is fixedly connected to the linear actuator 6 through bolts, and the bottom of the linear actuator 6 is fixedly connected to the top of the fixing frame 3 through bolts;

[0020] By adopting the above technical solution, the packaging, metering and related components inside the packaging frame 1 and on the storage box 2 can be used to complete the packaging of the powder. At the same time, after the material is filled into the packaging bag, the linear actuator 6 on the top of the fixed frame 3 can drive the vacuum head 14 to fit the vacuum hole of the packaging bag. At this time, the vacuum pump 4 can be turned on, and the air in the packaging bag can be extracted through the cooperation of the first telescopic hose 5, so that the packaging is more compact, and the filter plate 15 provided in the vacuum head 14 can effectively block the powder to avoid vacuum. The powder can be extracted together with the filter plate 15, and after the air extraction is completed, the linear actuator 6 can be contracted to drive the air extraction head 14 to move out of the packaging area. At this time, the drive motor 8 can be output to drive the screw rod 11 in the sliding groove 7 to rotate, thereby driving the recovery part provided on the surface of the screw rod 11 to move. When it is moved to the position of the air extraction head 14, the powder remaining on the filter plate 15 can be cleaned by the recovery part to avoid blockage and affect the subsequent air extraction effect. At the same time, the cleaned powder can be recovered into the storage box 2 for repackaging and use.

[0021] Reference Figure 1 and Figure 2 The recovery parts include a powder recovery pump 9, a second telescopic hose 10, a powder recovery head 13 and a threaded sleeve 12. The surface of the screw rod 11 is threadedly connected with the threaded sleeve 12. The inner cavity side wall of the threaded sleeve 12 is fixedly connected with the powder recovery head 13 by bolts. One side of the powder recovery head 13 is fixedly connected with the second telescopic hose 10 by a clamp. One end of the second telescopic hose 10 away from the powder recovery head 13 is fixedly connected with the powder recovery pump 9 by a clamp. One side of the powder recovery pump 9 is fixedly connected to one side of the storage box 2 by bolts.

[0022] By adopting the above technical solution, when the screw rod 11 rotates, the threaded sleeve 12 can be driven to move, so that the powder recovery head 13 can be driven to move to the corresponding position through the threaded sleeve 12. At this time, the powder recovery pump 9 can be opened and the filtered residual powder can be sucked into the storage box 2 fixedly connected to one side of the powder recovery pump 9 by using the second telescopic hose 10, thereby completing the recovery of the residual powder.

[0023] The implementation principle of the negative pressure exhaust device of a powder packaging machine in the embodiment of the present application is as follows: the packaging, metering and related components provided inside the packaging machine frame 1 and on the storage box 2 can complete the packaging of the powder. At the same time, after the material is filled into the packaging bag, the exhaust head 14 can be driven by the linear actuator 6 on the top of the fixed frame 3 to fit the exhaust hole of the packaging bag. At this time, the vacuum pump 4 can be turned on, and the air in the packaging bag can be extracted by the coordinated use of the first telescopic hose 5 to make the packaging more compact. The powder can be effectively blocked by the filter plate 15 provided in the exhaust head 14 to avoid the powder being extracted together during the exhaust. After the exhaust is completed, the linear actuator 6 can be contracted to drive the exhaust head 14 to move out of the packaging area. At this time, the drive motor 8 can be output to drive the screw rod 11 in the sliding groove 7 to rotate. When the screw rod 11 rotates, it can drive the threaded sleeve 12 The powder recovery head 13 is moved, thereby the threaded sleeve 12 can drive the powder recovery head 13 to move to the position of the exhaust head 14, so that the powder recovery head 13 is facing the exhaust end of the exhaust head 14. At this time, the powder recovery pump 9 can be opened, and the second telescopic hose 10 can be used to filter the residual powder on the filter plate 15 and suck it into the storage box 2 fixedly connected to one side of the powder recovery pump 9, so as to complete the cleaning of the residual powder on the filter plate 15 to avoid clogging and affecting the subsequent exhaust effect. At the same time, the cleaned powder is recovered into the storage box 2, and the powder can be repackaged and used. Correspondingly, the linear actuator 6 drives the exhaust head 14 to extend. When exhausting, it outputs through the drive motor 8 and cooperates with the screw rod to move the threaded sleeve 12 and the powder recovery head 13 to the side without affecting the normal movement and exhaust operation of the exhaust head 14. The above-mentioned drive motor 8 can be NEMA 17 stepper motor, NEMA 17 stepper motor is a synchronous motor that controls the movement of the rotor by applying a pulse signal. The linear actuator 6 mentioned above can be selected from the Warner Linear K2G20-12v-BR-04 model. The linear actuator 6 contains an electric motor, which is connected to the screw through a gear box to drive the screw to rotate. When the screw rotates, the push rod connected to the screw will move linearly to achieve the extension and retraction of the actuator. The whole process does not involve the rotational movement of any parts. When the motor stops working, the friction between the screw and the nut and the design of the gear box ensure that the push rod will not move due to external forces, realizing the self-locking function. The vacuum pump 4 powder recovery pump 9 mentioned above can all be selected from Alfafilter The AFM series air pump forms a movable space for a sealed container by rotating the vane blades around the central axis. When the vanes rotate, the gas in the packaging bag is sucked into the gap between the vanes of the vacuum pump 4 through the suction head 14 and the first telescopic hose 5. When the vanes rotate to the maximum volume, the gas in the packaging bag is squeezed to the outlet of the pump. At this time, the gas is discharged from the pump to form a negative pressure. The rotary vane vacuum pump continuously cycles inhalation and exhaust.It generates continuous negative pressure, and its key components are made of wear-resistant materials, which improves the durability and reliability of the pump. It can efficiently and stably absorb and recover the residual powder on the filter plate 15. The overall operation is simple to use. It can not only quickly clean the residual powder on its filter component to avoid excessive residual powder, causing blockage and affecting the actual pumping effect and packaging efficiency, but also can recover the residual material and repackage it for use, which can reduce the waste of powder.
