The screw feeder 3 includes a driving rod 302 and a screw blade 301, and the screw blade 301 is spirally provided around the driving rod 302. The spiral blade 301 extends from the bin 201 into the feed conveyor pipe 202 to the output end of the storage device 2. In the working process, the driving rod 302 drives the helical blade 301 to rotate, the helical blade 301 can push the material to move towards the direction of the output end of the material storage device 2, and during the period, the helical blade 301 can also extrude the material and is matched with the degassing device to discharge gas among material particles and increase the density of the material.

Meanwhile, the gap between the outer edge of the helical blade 301 and the inner wall of the conveying pipe 202 can be set as small as possible, so that the materials can move to the output end of the storage device 2 under the action of the helical blade 301 as much as possible, the materials can be fully extruded, and the material amount moving through the gap can be reduced. For example, the gap between the outer edge of the helical blade 301 and the inner wall of the feed delivery pipe 202 may be set to 0.8mm, 0, 9mm, 1mm, 1.1mm, 1.15mm, 1.2mm, 1.4mm, 1.5mm, etc.

The driver 4 may be electrically connected to the controller.

In some embodiments, the driving member 4 may be a motor. The output end of the driving member 4 is connected to the input end of the speed reducer 5, and the output shaft 501 of the speed reducer 5 is connected to the spiral conveying device 3. Specifically, the output shaft 501 may be in transmission connection with one end of the transmission shaft 6 through the coupling 15. The other end of the transmission shaft 6 is fixedly connected with the spiral material conveying device 3. Thereby, the screw conveyor 3 is driven to rotate under the action of the driving piece 4.

In an embodiment, the driving member 4 and the speed reducer 5 may be fixedly mounted above the frame 1 through the mounting seat 101, that is, at an end of the frame 1 close to the storage bin 201.

An output shaft 501 of the speed reducer 5 extends into the mounting seat 101 to be connected with the transmission shaft 6, and the other end of the transmission shaft 6 penetrates through the mounting seat 101 to enter the storage bin 201 to be connected with the spiral conveying device 3. In order to ensure the working stability of the transmission shaft 6, a bearing 16 can be arranged between the transmission shaft 6 and the mounting seat 101, so that on one hand, the transmission shaft 6 can be ensured to rotate smoothly relative to the mounting seat 101, and on the other hand, the transmission shaft 6 can be correspondingly supported, the radial vibration of the transmission shaft 6 is reduced, and the working stability is improved.

Of course, in other embodiments, the driving member 4 may be an air cylinder, and cooperate with the clutch device and the gear transmission device to drive the screw conveyor 3 to rotate in one direction.

As shown in FIG. 1, the degassing devices are all disposed around the delivery pipe 202. Specifically, the degassing device may be an annular hood structure disposed around the delivery conduit 202. The cover body is communicated with the interior of the material conveying pipe 202, and meanwhile, one side, far away from the material conveying pipe 202, of the cover body is a sealing structure. Therefore, in the working process, negative pressure can be pumped in the cover body, so that air in the conveying pipe 202, namely air in the material, can be pumped away under the action of the negative pressure.

In some embodiments, the wall of the delivery conduit 202 may be hollow and double-layered, and the degasser may be disposed within the hollow wall of the delivery conduit 202 and adjacent to the inner layer.

Of course, in other embodiments, the wall of the feed conveyor pipe 202 may be provided as a single layer, with the degasser being provided directly around the outer wall of the feed conveyor pipe 202.

In the present embodiment, the degassing device is provided with two, i.e., a first degassing device 7 and a second degassing device 8. Wherein, first degasser 7 sets up in the one end that the conveying pipeline 202 is close to feed bin 201, and second degasser 8 sets up in the one end that feed bin 201 was kept away from to storage pipe 202, and second degasser 8 is close to the output setting of storage device 2 promptly.

In some embodiments, the first degassing device 7 may be disposed corresponding to the position of the second section of the helical blade 3012, the second degassing device 8 may be disposed corresponding to the position of the first section of the helical blade 3011, and the second degassing device 8 is disposed near the output end of the conveying pipe 202, i.e., the output end of the stock device 2.

In the working process, under the extrusion action of the second section of the helical blade 3012, air in the material is gradually extruded out towards the side wall of the material conveying pipe 202, i.e. towards the first degassing device 7. The first degassing device 7 can pump away this part of the extruded air to achieve a first stage of degassing of the material. During the process of gradually conveying the material to the output end, the first section of the helical blade 3011 can gradually pressurize and extrude the material, so as to further extrude the residual air in the material, and the second degassing device 8 can pump away the air, so as to realize the second-stage degassing treatment of the material. Through the gradually pressurized extrusion process of the spiral blade 301 and the degassing treatment of the first degassing device 7 and the second degassing device 8, the air in the material can be discharged outwards as much as possible, so that the air content in the material can be effectively reduced, the density of the material can be improved, and the material in the material bag 18 can reach the required weight. When the material bag 18 is replaced, the material conveying action of the spiral material conveying device 3 can be stopped, and the material can be prevented from leaking outwards through the output end of the material conveying pipe 202 under the adsorption action of the second degassing device 8, namely, the problem of material leakage when the material bag 18 is replaced is avoided, so that the material waste is avoided.

It should be noted that the first degassing device 7 and the second degassing device 8 are disposed around the material conveying pipe 202, so that the passing materials can be subjected to all-directional degassing treatment, and omission is avoided. That is, when the material passes through the first degassing device 7 or the second degassing device 8, the air in the material can be sucked away by the corresponding first degassing device 7 or the second degassing device 8 regardless of the direction in which the air is pushed out by the helical blade 301.

In an embodiment, the micropowder packaging machine further comprises a negative pressure device 11, the negative pressure device 11 is respectively communicated with the first degassing device 7 and the second degassing device 8, and the negative pressure device 11 can be electrically connected with the controller. The negative pressure device 11 is used for providing negative pressure conditions for the first degassing device 7 and the second degassing device 8, namely, the interior of the first degassing device 7 and the second degassing device 8 is in a negative pressure state under the action of the negative pressure device 11. Therefore, under the action of negative pressure, air among materials in the material conveying pipe 202 can be pumped away, so that the degassing treatment of the materials is realized.

Because the first degassing device 7 and the second degassing device 8 are arranged at intervals, the materials are subjected to segmented degassing treatment. Therefore, compare in present full route degasification processing, the miropowder packagine machine that this application provided can be when guaranteeing to carry out effective degasification to the material, reducible negative pressure device 11's work load, and then play corresponding guard action to negative pressure device 11, reduce its loss, extension negative pressure device 11's life.

In some embodiments, the first degassing device 7 and the second degassing device 8 are provided with a screen on the side close to the feed conveyor pipe 202. It will be appreciated that the sieve 17 is placed in a position where the first degassing device 7 communicates with the feed conveyor 202, and that the second degassing device 8 communicates with the feed conveyor 202. The screen 17 serves to isolate the material, i.e. to stop it in the feed pipe 202, so that it is prevented from being drawn out together under the action of the negative pressure. Specifically, the aperture of the screen 17 is smaller than the particle size of the material, so that the material is prevented from passing through the screen 17. Therefore, on one hand, the material can be prevented from entering the negative pressure device 11 to damage the negative pressure device 11, and on the other hand, the waste of the material can be avoided.

Further, as shown in fig. 1, the micropowder packaging machine further comprises an air blowing device 10, and the air blowing device 10 can be electrically connected with the controller. The blowing means 10 are provided in communication with the first degassing means 7 and the second degassing means 8, respectively. The blowing device 10 is used to deliver a positive pressure air flow into the first degassing device 7 and the second degassing device 8, so that the material attached to the screen 17 can be blown down into the feed delivery pipe 202, and the screen 17 is prevented from being clogged. In use, the user can clean the filter screens 17 at the positions of the first degassing device 7 and the second degassing device 8 regularly through the blowing device 10 to ensure the smooth operation of the micropowder packaging machine and ensure the working quality.

In some embodiments, the blowing device 10 may be one of a blower, a fan, and the like.

In other embodiments, the number of the degassing device can be three, four, five, etc., and can be specifically set according to the length of the conveying pipe 202, so as to ensure that the material is subjected to effective degassing treatment and the air content in the material is reduced. At least one degasser is disposed at the output end of the feed pipe 202 to avoid leakage when the bag 18 is replaced.

In the embodiment shown in fig. 1, 3 and 4, the output end of the conveying pipe 202 is further provided with a striker plate 9, and the striker plate 9 is used for stopping the circumferential edge of the output end of the conveying pipe 202 to prevent the material from leaking. In the embodiment, in order to ensure the smooth rotation of the helical blade 301, a gap is provided between the helical blade 301 and the conveying pipe 202, wherein the striker plate 9 can block the material passing through the gap, and the material is prevented from being directly discharged from the output end of the conveying pipe 202 after passing through the gap. Therefore, the materials discharged from the conveying pipe 202 are extruded by the helical blades 301 and degassed by the degassing device, so that the discharged materials have higher density.

In some embodiments, the weighing device 13 may be an electronic scale, and the weighing device 13 is electrically connected to the controller. The weighing device 13 can feed back the weight of the material in the material bag 18 to the controller in real time, and when the weight of the material in the material bag 18 reaches the standard, the controller can control the driving member 4 to stop so as to stop the spiral conveying device 3, namely stop the output of the material, so that a user can replace the material bag 18 conveniently.

Further, in the embodiment, a lifting bracket 12 is further disposed on one side of the weighing device 13 close to the storage device 2, and the lifting bracket 12 can be adjusted in height according to the weight of the material in the material bag 18. Specifically, when the initial stage of feeding to pocket 18, lifting support 12 can have higher height to reduce the height that the material dropped, thereby avoid the material to take place the great rigidity collision of effort and scatter after getting into pocket 18, and then avoid material density to diminish. Meanwhile, the weighing device 13 can be prevented from being greatly impacted, and the weighing device 13 is prevented from being damaged.

When the weight of the materials in the material bag 18 is gradually increased, the height of the lifting support 12 can be gradually reduced to provide sufficient placing space for the materials and avoid material leakage.

In some embodiments, the lifting frame 12 may be an electric lifting frame, i.e., a driving device such as an electric push rod, an electric cylinder, and a motor drives the upper panel of the lifting frame 12 to lift. Of course, the driving device is electrically connected to a controller, and the controller can control the lifting bracket 12 to adjust the height according to the signal fed back by the weighing device 13.

In other embodiments, the lifting frame 12 may be an elastic frame, i.e. the height of the lifting frame 12 may be gradually reduced under the action of the gravity of the material. The height of the lifting bracket 12 can be reset when the material bag 18 is to be replaced.
