The traditional powder discharging machine includes a fixed tray and a rotating tray rotatably installed on the fixed tray. A plurality of discharging holes are formed in the rotating tray, and a discharging hole is formed in the fixed tray. When the discharging hole is rotated to the discharging hole, the powder in the rotating tray will fall from the discharging hole.

[0003] The prior art, such as CN 104097794 A, discloses a powder automatic discharging and packaging device. It is pointed out in the document that since the fineness of the powder is small, a large amount of powder gathered at the discharge port is easy to cause blockage, affecting the smooth discharging of the powder on the upper part of the hopper. When the hopper is blocked, the upper cover of the hopper needs to be opened manually, and a tool is used for dredging, which reduces the efficiency of powder packaging. The specific technical features are: a driving device is arranged above the hopper of the powder packaging machine, the driving device drives a rotating shaft provided with stirring blades, the lowermost end of the rotating shaft is provided with a screw rod, and when the driving device rotates, the stirring blades rotate with it, so that the powder greatly reduces the downward gathering and blockage of the discharge port of the hopper; a guide sleeve made of wear-resistant material is arranged at the discharge port of the hopper, which prolongs the service life of the inner circle of the discharge port of the hopper.

[0004] Another prior art is:

[0005] CN 114180116 A, a powder continuous automatic discharging device

[0006] However, the above-mentioned and other typical prior arts still have certain problems in use:

[0007] Based on the above, the anti-blocking mechanism is added in the process of powder discharging to realize smooth discharging, but the discharging amount of powder is difficult to accurately control, and the powder amount of part of the seasoning bag is uneven, the weight sensor is added in the device to control the discharging amount, so that the structure of the whole device becomes complex, the manufacturing cost is greatly improved, and at the same time, the container needs to be frequently taken and placed to the position of the discharging hopper in the process of discharging, and then the valve on the discharging hopper is controlled to open / close, so that the operation is extremely complex, and there is a long time gap in the discharging work in the process of taking and placing the container, so that it is difficult to realize the purpose of automatic and continuous feeding, and for batch feeding work, the feeding efficiency is undoubtedly greatly reduced, which is not conducive to the production and operation of powder, therefore, an automatic discharging device for powder packaging machine and a discharging method thereof are provided to solve the above problems. SUMMARY

[0008] The purpose of the present application is to provide an automatic discharging device for powder packaging machine and a discharging method thereof to solve the problems in the background art.

[0009] To achieve the above purpose, the present application provides the following technical scheme: an automatic discharging device for powder packaging machine, comprising a bottom plate, a support is fixedly connected to the bottom plate, a material barrel is clamped in the middle of the support, four feeding ports are formed in the material barrel, a turnover box is connected to the bottom of the material barrel, a discharging box is fixed to the bottom of the turnover box, a hopper is connected to the bottom of the discharging box, a driving shaft is arranged at the top of the material barrel, a material guiding assembly is fixed to the driving shaft, the material guiding assembly is located in the material barrel and the turnover box, a knocking assembly is arranged at the bottom end of the material guiding assembly, a discharging roller is arranged in the discharging box, four material grooves are formed outside the discharging roller, an adjusting assembly is connected inside the discharging roller, a driving assembly is fixed to one end of the discharging roller, one side of the driving assembly is fixedly connected to one side in the support, a transmission assembly is arranged on the driving assembly, and the transmission assembly is fixed to the transmission shaft of the conveying mechanism.

[0012] By adopting the technical scheme, the spiral blade can crush the lumpy powder in the rotating process, uniformly deliver the powder downward, improve the feeding uniformity, and be beneficial to subsequent powder scattering and loading work, and the stirring rod can scatter the powder, so that the powder cannot be accumulated at the same position.

[0013] As a preferred technical scheme of the present application, the knocking assembly comprises a fixed block fixed with the bottom end of the connecting shaft, a stand column arranged in the fixed block, and elastic expansion rods connected with the two sides of the stand column.

[0015] As a preferred technical scheme of the present application, the knocking rod penetrates through the fixed block, and the end of the knocking rod away from the fixed block is designed in a circular arc shape, the four sides of the turnover box are fixedly connected with stoppers, and the side of the stopper close to the knocking rod is designed in an arc shape.

[0016] By adopting the technical scheme, in the process of pressing the stopper, the knocking rod can slide on the arc surface of the stopper, so that the knocking rod can normally rotate, and in cooperation with the arrangement of the plurality of stoppers, the knocking rod can continuously knock the turnover box, and the clearing effect is improved.

[0017] As a preferred technical scheme of the present application, the adjusting assembly comprises a lead screw arranged at the two sides in the powder chute, a nut externally screwed with the lead screw, connecting rods hinged with the nut through pins, and a supporting plate hinged with the top end of the connecting rod through a pin.

[0018] By adopting the technical scheme, the nut can drive the four supporting plates through the four connecting rods, so that the four supporting plates are away from each other, the supporting plates slide in the powder chute, the volume of the powder chute can be adjusted, the purpose of adjusting the powder feeding amount can be achieved, and the powder feeding amount can be accurately controlled.

[0019] As a preferred technical scheme of the present application, the two ends of the powder chute are provided with fixed sleeves, one of the fixed sleeves is provided with a shaft sleeve, the lead screw is arranged in the shaft sleeve, and a handle is connected with the end of the lead screw away from the fixed sleeve.

[0020] By adopting the technical scheme, rotating the handle can drive the lead screw to rotate, the volume of the powder chute can be adjusted from the outside of the device, and the operation is very convenient.

[0021] As a preferred embodiment of the present invention, the drive assembly includes a motor, one side of the motor body is fixed to a bracket, a turntable is fixed to the output shaft of the motor, an arc-shaped groove is provided at the bottom of the turntable, a lever is provided directly below the groove, the lever is fixed to a vertical plate, and the top of the vertical plate is engaged with the output shaft of the motor.

[0022] By adopting the above technical solution: during the rotation of the turntable, the lever can rotate and slide into the guide rail on the drive plate. As the lever continues to rotate, it can push the drive plate to rotate 90 degrees until the lever disengages from the guide rail. At the same time, the outer wall of the turntable slides into the limiting groove, so that the drive plate will not rotate freely, thereby improving the stability of the feeding roller guiding the material and subsequent loading.

[0023] As a preferred embodiment of the present invention, a drive disk is provided outside the turntable, one side of the drive disk is fixed to one end of the feeding roller, and four limiting grooves and four guide rails are provided outside the drive disk, with the included angle between two adjacent limiting grooves and two adjacent guide rails being 90 degrees.

[0024] By adopting the above technical solution, the guide rail can limit the position of the lever, and the continued rotation of the lever can squeeze the drive plate through the guide rail, which facilitates the adjustment of the angle of the drive plate and the feed roller.

[0025] As a preferred embodiment of the present invention, the transmission assembly includes a driving wheel and a driven wheel. The driving wheel is connected to the driven wheel via a transmission belt, and one end of the driven wheel is connected to the transmission shaft of the conveying mechanism.

[0026] By adopting the above technical solution, the driving wheel drives the driven wheel to rotate through the transmission belt, and the driven wheel drives the conveying mechanism to transmit intermittently without the need for manual assistance, so that the feeding and loading operations can be carried out simultaneously, thereby improving the feeding stability.

[0027] An automatic feeding method for a powder packaging machine includes the following steps:

[0028] S1. After the powder is placed into the hopper through the feed inlet, the drive shaft drives the connecting shaft to rotate. The connecting shaft drives the spiral blade to rotate through the conical seat. During the rotation, the spiral blade can crush the clumps of powder and convey the powder evenly downward. When the powder falls from the spiral blade, the connecting shaft drives the stirring rod to rotate, so that the stirring rod can disperse the powder and prevent the powder from piling up in the same position.

[0029] S2. After the powder is broken up, it falls into the trough on the feeding roller. The motor works to drive the turntable to rotate. During the rotation of the turntable, it can rotate through the lever and slide into the guide rail on the drive plate. As the lever continues to rotate, it can push the drive plate to rotate 90 degrees until the lever disengages from the guide rail. At the same time, the outer wall of the turntable slides into the limiting groove, so that the drive plate will not rotate freely. During this process, the drive plate can drive the feeding roller and the powder to rotate 90 degrees.

[0030] S3. Because the motor works continuously, the feeding roller can rotate intermittently by 90 degrees until the powder is discharged from the hopper. A container is placed on the conveying mechanism, and the powder can fall into the container. Because the drive disc and the drive wheel rotate, the drive wheel drives the driven wheel to rotate through the transmission belt. The driven wheel then drives the conveying mechanism to convey intermittently. No manual operation is required, which reduces the time gap in the feeding operation and achieves the purpose of automated continuous feeding.

[0031] S4. During the process of the drive shaft driving the connecting shaft to rotate, the connecting shaft drives the fixed block to rotate, and the fixed block drives the two striking rods to rotate. After the striking rods come into contact with the arc-shaped stop, the striking rods drive the elastic telescopic rods to retract. After the striking rods are separated from the stop, they quickly strike the inner wall of the turnover box through the elastic force of the elastic telescopic rods, shaking off the residual powder on the inner wall of the turnover box. The vibration generated can also expel the air in the powder in the trough, making the powder more compact.

[0032] S5. When it is necessary to adjust the amount of powder to be fed, the handle is turned so that the screw can rotate. During the rotation of the screw, the nut can move outside the screw, so that the nut can push the four support plates through the four connecting rods, so that the four support plates move away from each other and slide in the material trough. Thus, the volume in the material trough can be adjusted, thereby achieving the purpose of adjusting the amount of powder to be fed.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] The application is characterized in that: the powder is scattered and then falls into the chute on the discharging roller; the motor works to drive the rotating disc to rotate; the rotating disc rotates to rotate the driving disc through the rotating and sliding of the driving disc into the guide rail on the driving disc; the driving disc rotates 90 degrees to separate from the guide rail; the outer wall of the rotating disc slides into the limiting groove to prevent the driving disc from rotating freely; the driving disc drives the discharging roller and the powder to rotate 90 degrees; the discharging roller can realize intermittent 90-degree rotation due to the continuous work of the motor; the powder is discharged from the hopper; the container is placed on the conveying mechanism; the powder falls into the container; the driving disc and the driving wheel rotate to drive the driven wheel to rotate through the transmission belt; the driven wheel drives the conveying mechanism to intermittently convey; the manual operation is not needed; the time gap of the discharging work is reduced; the automatic and continuous loading is realized; the loading efficiency is improved; and the production and loading operation of the powder are facilitated.

[0035] The connecting shaft drives the conical seat and the spiral blade to rotate; the spiral blade can crush the clumped powder in the rotating process; the powder is uniformly downward conveyed; the connecting shaft drives the stirring rod to rotate when the powder falls from the spiral blade; the stirring rod can scatter the powder; the powder cannot be accumulated at the same position; the connecting shaft drives the fixed block to rotate; the fixed block drives the two knocking rods to rotate; the knocking rod contacts the arc-shaped block to drive the elastic expansion rod to contract; the knocking rod separates from the block to be rapidly knocked against the inner wall of the turnover box through the elastic force of the elastic expansion rod; the residual powder in the inner wall of the turnover box is shaken off; the vibration can discharge the air in the chute; the powder is more compact; and the uniformity of the powder conveying is improved.
