Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a fully automatic powder dispensing and packaging device. Background Technology

[0002] In industries such as food, pharmaceuticals, and chemicals, the demand for automated powder packaging is growing rapidly. Fully automated powder packaging equipment, with its high efficiency and precision, has greatly promoted large-scale production in these industries. However, in actual production, the "arching effect" at the discharge stage, leading to blockages, has become a key bottleneck restricting the improvement of production efficiency and product quality.

[0003] Existing powder dispensing and packaging devices also have certain limitations in structural design, which further exacerbates the problem of discharge blockage. In traditional devices, the flow path of powder in the box is relatively simple and lacks an effective unblocking mechanism. When the powder forms an "arching effect" in the box or at the discharge port, it cannot be dispersed and loosened in time, resulting in a continuous increase in the accumulation density and eventually clogging the discharge port. Utility Model Content

[0004] In view of this, the present invention provides a fully automatic powder dispensing and packaging device, which aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic powder dispensing and packaging device, comprising: The box body has a feed inlet at the top and a discharge outlet at the bottom. A dredging shaft is vertically installed inside the box, with its lower end extending to the discharge port. The dredging shaft is equipped with multiple material-pulling rods. The dredging shaft is connected to a rotating assembly, and a drive assembly drives the dredging shaft to rotate through the rotating assembly. The dredging shaft is also connected to a lifting assembly, and the drive assembly drives the dredging shaft to rise and fall through the lifting assembly. The dredging shaft rotates continuously during both rising and falling. A conveying cylinder is horizontally fixed at the lower end of the box body. A rotatable auger is provided inside the conveying cylinder. The powder inlet at the first end of the conveying cylinder is connected to the discharge outlet. A powder outlet pipe is provided on the lower side of the second end of the conveying cylinder. Clamping components are located at both ends of the powder outlet pipe and are used to clamp the powder bag. A heat-sealing assembly, located below the clamping assembly, is used for heat-sealing powder bags.

[0006] A further improvement of this utility model is that the unblocking shaft includes an upper fixed rod and a lower rotating rod, the upper end of the rotating rod is connected to the lower end of the fixed rod via a rotating shaft, the rotating rod is connected to a rotating assembly, and the fixed rod is connected to a lifting assembly.

[0007] A further improvement of this utility model is that the driving component includes a first rotating shaft, which rotates under the drive of a first motor, and the first rotating shaft is connected to a lifting component and a rotating component respectively.

[0008] A further improvement of this utility model is that a first guide key is fixedly provided on the fixing rod along its axial direction, a support plate is fixedly provided on the housing, the upper end of the fixing rod passes through the support plate, and the first guide key is slidably connected to a first guide groove on the support plate. The lifting assembly includes: A cylindrical guide wheel is fixed on the first rotating shaft and coaxial with it; The guide post is horizontally fixed on the fixed rod and is slidably connected to and adapted to the guide curve provided on the cylindrical guide wheel. When the cylindrical guide wheel rotates, the fixed rod performs a reciprocating lifting and lowering motion, and the fixed rod drives the rotating rod to lift and lower synchronously.

[0009] A further improvement of this utility model is that the rotating assembly includes: The first gear is fixed on the first rotating shaft; A rotating sleeve is mounted on the housing. The upper end of the rotating rod passes through the top of the housing and the rotating sleeve. A second guide key fixed on the rotating rod along its axial direction is slidably connected to a second guide groove on the inner wall of the rotating sleeve. A second gear fixed on the rotating sleeve meshes with the first gear.

[0010] A further improvement of this utility model is that the clamping assembly includes two clamping plates, symmetrically arranged at both ends of the powder outlet pipe, and driven by two first cylinders to move away from or closer to the powder outlet pipe.

[0011] A further improvement of this utility model is that the heat sealing assembly includes a baffle and a heat sealing block, which are disposed opposite each other on both sides of the powder outlet pipe below the clamping assembly. The baffle and the heat sealing block are driven by two second cylinders to move closer to or further away from each other.

[0012] A further improvement of this utility model is that the feed inlet is provided with an openable and closable cover.

[0013] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows: This invention provides a fully automatic powder dispensing and packaging device. When the powder forms an arched structure inside the box or at the discharge port, the drive component drives the unblocking shaft to rotate continuously through the rotating component.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0018] This utility model provides a fully automatic powder dispensing and packaging device, which, in conjunction with the accompanying instruction manual, is described below. Figure 1 To be continued Figure 4It can be seen that a fully automatic powder dispensing and packaging device mainly includes the following parts or components: box body 10, unblocking shaft 11, conveying cylinder 13, clamping assembly 50, and heat sealing assembly 60.

[0019] In this invention, the upper end of the housing 10 is provided with an inlet 101 and the lower end with an outlet 102; the unblocking shaft 11 is vertically arranged inside the housing 10, with its lower end extending to the outlet 102. The unblocking shaft 11 is provided with multiple push rods 12. The unblocking shaft 11 is connected to the rotating assembly 40, and the driving assembly 20 drives the unblocking shaft 11 to rotate via the rotating assembly 40. The unblocking shaft 11 is connected to the lifting assembly 30, and the driving assembly 20 drives the unblocking shaft 11 to rotate via the lifting assembly 30. 1. Lifting and lowering, and the unblocking shaft 11 always rotates during lifting and lowering; the conveying cylinder 13 is horizontally fixed at the lower end of the box body 10, and a rotatable auger (not shown in the figure) is provided inside the conveying cylinder 13. The powder inlet (not shown in the figure) at the first end of the conveying cylinder 13 is connected to the discharge port 102, and a powder outlet pipe 131 is provided on the lower side of the second end of the conveying cylinder 13; the clamping assembly 50 is provided at both ends of the powder outlet pipe 131 for clamping the powder bag; the heat sealing assembly 60 is provided below the clamping assembly 50 for heat sealing the powder bag.

[0020] The powder is placed into the housing 10 through the feed inlet 101. The drive assembly 20 starts working, and the rotating assembly 40 drives the unblocking shaft 11 to rotate. At the same time, the lifting assembly 30 drives the unblocking shaft 11 to reciprocate and lift, and the unblocking shaft 11 remains rotating during the lifting process. Multiple feeding rods 12, along with the rotation and lifting of the unblocking shaft 11, agitate and disperse the powder in all directions within the housing 10, effectively preventing the powder from forming an "arch bridge effect" in the housing 10 or at the discharge port 102, ensuring that the powder can fall smoothly from the discharge port 102. After falling from the discharge port 102, the powder enters the powder inlet at the first end of the conveying cylinder 13, which is connected to the discharge port 102. Then, the rotating auger transports the powder to the powder outlet pipe 131. When the powder reaches the powder outlet pipe 131, the clamping assembly... The clamping component 50 begins to function, firmly holding the powder bag placed below the powder outlet pipe 131 to ensure that the powder bag is fixed in position during the powder receiving process and to prevent powder from spilling. Once the powder in the powder bag reaches the preset weight or capacity, the clamping component 50 maintains the clamping state of the powder bag, and the heat sealing component 60 is then activated to heat and seal the opening of the powder bag, sealing the powder bag filled with powder. After the heat sealing is completed, the clamping component 50 moves away from the powder outlet pipe 131 and releases the packaged powder bag.

[0021] When the powder forms an arched structure inside the housing 10 or at the discharge port 102, the drive component 20 drives the unblocking shaft 11 to rotate continuously through the rotating component 40, and the feeding rod 12 agitates the accumulated powder in all directions, destroying the mutual support force between the particles; at the same time, the drive component 20 drives the unblocking shaft 11 to move up and down through the lifting component 30, further enhancing the dispersion effect of the powder, which can effectively prevent the formation of the arched structure, ensure the smooth fall of the powder, and greatly improve the discharge efficiency and stability.

[0022] As one embodiment, in conjunction with the appendix to the specification Figure 2 To be continued Figure 3 It is understood that the unblocking shaft 11 includes an upper fixed rod 111 and a lower rotating rod 113. The upper end of the rotating rod 113 is connected to the lower end of the fixed rod 111 via a rotating shaft. The rotating rod 113 is connected to the rotating assembly 40, and the fixed rod 111 is connected to the lifting assembly 30. The drive assembly 20 includes a first rotating shaft 21, which rotates under the drive of the first motor 22. The first rotating shaft 21 is connected to the lifting assembly 30 and the rotating assembly 40, respectively. A first guide key 112 is fixed on the fixed rod 111 along its axial direction. A support plate 115 is fixed on the housing 10. The upper end of the fixed rod 111 passes through the support plate 115, and the first guide key 112 is slidably connected to the first guide groove (not shown in the figure) on the support plate 115. The lifting assembly 30 includes a cylindrical guide wheel 31, which is fixed on the first rotating shaft 21 and coaxial with it. The guide column 33 is horizontally fixed on the fixed rod 111 and is slidably connected to and adapted to the guide curve 32 provided on the cylindrical guide wheel 31. When the cylindrical guide wheel 31 rotates, the fixed rod 111 performs a reciprocating lifting motion, and the fixed rod 111 drives the rotating rod 113 to lift synchronously. The rotating assembly 40 includes a first gear 211, which is fixed on the first rotating shaft 21; a rotating sleeve 41 is rotatably mounted on the housing 10; the upper end of the rotating rod 113 passes through the top of the housing 10 and the rotating sleeve 41; a second guide key 114 fixed on the rotating rod 113 along its axial direction is slidably connected to a second guide groove (not shown in the figure) on the inner wall of the rotating sleeve 41; and a second gear 42 fixed on the rotating sleeve 41 meshes with the first gear 211.

[0023] The first motor 22 drives the first rotating shaft 21 to rotate synchronously. The first gear 211 on the first rotating shaft 21 meshes with the second gear 42 on the rotating sleeve 41, causing the rotating sleeve 41 to rotate. Since the rotating rod 113 is slidably connected to the second guide groove on the inner wall of the rotating sleeve 41 through the second guide key 114, the rotation of the rotating sleeve 41 will drive the rotating rod 113 to rotate synchronously. The first rotating shaft 21 drives the cylindrical guide wheel 31 to rotate synchronously, and the guide curve 32 on its surface is slidably engaged with the guide post 33 on the fixed rod 111. When the guide wheel rotates, the guide post 33 moves along the guide curve 32, forcing the fixed rod 111 to perform reciprocating lifting and lowering motion under the constraint of the first guide key 112 and the first guide groove of the support plate 115. The fixed rod 111 drives the rotating rod 113 to rise and fall, so that the rotating rod 113 rises and falls at the same time as it rotates. Since the fixed rod 111 and the rotating rod 113 are connected by a rotating shaft, and since the first guide key 112 is slidably connected to the first guide groove, the fixed rod 111 will not rotate when the rotating rod 113 rotates.

[0024] Specifically, the feeding rod 12 is installed on the rotating rod 113 inside the housing 10.

[0025] As one embodiment, in conjunction with the appendix to the specification Figure 4 It is understood that the clamping assembly 50 includes two clamping plates 51, symmetrically arranged at both ends of the powder outlet pipe 131, and driven by two first cylinders 52, moving away from or closer to the powder outlet pipe 131. The heat sealing assembly 60 includes a baffle 61 and a heat sealing block 62, which are arranged opposite each other on both sides of the powder outlet pipe 131 below the clamping assembly 50. The baffle 61 and the heat sealing block 62 move closer to or further away from each other under the drive of two second cylinders 63.

[0026] Once the powder reaches the powder outlet pipe 131, the clamping assembly 50 begins to function. Two clamping plates 51 located at both ends of the powder outlet pipe 131, driven by two first cylinders 52, move closer to the powder outlet pipe 131, firmly clamping the powder-holding bag placed below the powder outlet pipe 131. This ensures the powder-holding bag remains in a fixed position during powder collection, preventing powder spillage. Once the powder in the bag reaches a preset weight or capacity, the clamping assembly 50 maintains its clamping position on the bag, and the heat-sealing assembly 60 is activated. The baffle 61 and heat-sealing block 62 located below the clamping assembly 50, driven by two second cylinders 63, move closer together. The heat-sealing block 62 heats and heat-seals the opening of the powder-holding bag, sealing the bag filled with powder. After heat sealing, the two clamping plates 51 of the clamping assembly 50, driven by the first cylinders 52, move away from the powder outlet pipe 131, releasing the packaged powder-holding bag. The packaged powder product can then be removed manually or using other conveying equipment.

[0027] As one embodiment, in conjunction with the appendix to the specification Figure 1It is known that the feed inlet 101 is equipped with an openable and closable cover 14. Open the openable and closable cover 14 of the feed inlet 101, pour the powder to be packaged into the box 10, and then close the cover 14 to prevent external dust and impurities from entering the box 10 and contaminating the powder.
