[0022] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] It should be noted that when a component is referred to as "mounted on", "fixed to", or "disposed on" another component, it can be directly on the other component or there may be an intermediate component present at the same time. When a component is referred to as "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present at the same time.

[0024] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0025] The present invention provides a powder packaging machine for desiccant packaging, which includes a powder shaking mechanism 1, a hopper 2, a blanking die 3, a film unwinding mechanism 4, a longitudinal sealing mechanism 5, and a transverse sealing mechanism 6. The powder material passes through the powder shaking mechanism 1 from top to bottom and enters the hopper 2. The powder shaking mechanism 1 is mounted on the hopper 2 to shake the powder material, make the powder material loose and mix evenly. Subsequently, the powder material in the hopper 2 enters the blanking die 3. At the same time, the film unwinding mechanism 4 supplies the film. The film used for bag making here is a double-layer film, which is subjected to thermoplastic sealing treatment by the longitudinal sealing mechanism 5 and the transverse sealing mechanism 6. Specifically, the film is longitudinally sealed by the longitudinal sealing mechanism 5 and transversely sealed by the transverse sealing mechanism 6 to initially form a film bag with only an upward opening. At this time, the blanking die 3 injects the powder material into the film bag, and then the film bag filled with the powder material continues to move downward, and is transversely sealed by the transverse sealing mechanism 6 to complete the packaging of the powder material. The structure of the present invention is simple, the material discharge is stable, and the automatic packaging and discharging of the desiccant are realized.

[0026] Furthermore, the powder packaging machine for desiccant packaging provided by the present invention further includes a screw feeding component 7 for controlling the discharge amount. The screw feeding component 7 is disposed on the blanking die 3, and the screw feeding component 7 controls the discharge of the hopper to the blanking die 3.

[0027] Furthermore, the powder packaging machine for desiccant encapsulation provided by the present invention further includes a longitudinal cutting mechanism 81, which is disposed below the transverse sealing mechanism 6 and is used for trimming the longitudinal edges of the sealed packaging bag, so that the packaging bags are discharged in the form of a continuous strip. Furthermore, the powder packaging machine for desiccant encapsulation provided by the present invention further includes a transverse cutting mechanism 82, which is disposed below the longitudinal cutting mechanism 81 and is used for trimming the transverse edges of the sealed packaging bag, so that the packaging bags are discharged in units of each bag. Furthermore, the powder packaging machine for desiccant encapsulation provided by the present invention further includes a finished product output mechanism 92 for transporting the sealed and cut packaging bags, and the finished product output mechanism 92 is located below the transverse cutting mechanism 82. The finished product output mechanism 92 can directly adopt a conveyor belt to transport the finished products out of the powder packaging machine for the next-level processing. It should be noted that for the unwinding mechanism 4, the longitudinal sealing mechanism 5, the transverse sealing mechanism 6, the longitudinal cutting mechanism 81, the transverse cutting mechanism 82, and the finished product output mechanism 92 in the present invention, there are existing technologies for selection, and their specific structures will not be elaborated here.

[0028] Furthermore, the powder packaging machine for desiccant encapsulation provided by the present invention further includes a hopper lifting mechanism 91 for lifting the height of the hopper, and the hopper lifting mechanism 91 is disposed on one side of the hopper 2. Specifically, the hopper lifting mechanism 91 includes a servo motor (not labeled in the figure), a slider (not labeled in the figure), and a guide rod (not labeled in the figure). The slider is fixedly connected to the hopper and is driven by the servo motor to slide on the vertical guide rod, so as to realize the adjustment of the hopper height.

[0029] As Figure 2 , Figure 3As shown, preferably, the powder shaking mechanism 1 of the powder packaging machine for desiccant encapsulation provided by the present invention includes a driving machine 11, a cover plate 12, a blanking pipe 13, and a powder shaking component 14. The driving machine 11 is installed above the cover plate 12. The blanking pipe 13 is disposed through the cover plate 12. The powder shaking component 14 is arranged below the cover plate 12 and is driven by the driving machine 11. The powder shaking mechanism 1 is installed on the hopper 2 of the powder packaging machine through the cover plate 12 to close the upper port of the hopper 2. The upper end of the blanking pipe 13 is connected to an external transportation pipeline. The powder to be encapsulated is transported from the external transportation pipeline to the blanking pipe 13 and enters the hopper 2 through the blanking pipe 13. The driving machine 11 drives the powder shaking component 14 to reciprocate up and down, so that the powder in the hopper 2 is loosened and evenly distributed, so as to output and feed the powder from the lower port of the hopper 2. The hopper 2 of the powder packaging machine is used to carry the powder. Generally, the powder will accumulate at the lower part of the hopper 2. The powder shaking mechanism is used to disperse the powder accumulated in the hopper 2 and mix it evenly for the discharge of the lower port. Further, the powder shaking mechanism 1 further includes a guiding component 15. The guiding component 15 is installed on the cover plate 12 and sleeved on one end of the powder shaking component 14, so that the powder shaking component 14 moves up and down along a fixed direction when moving. The guiding component 14 is mainly used for the movable assembly between the powder shaking component 14 and the cover plate 12, fixing the movement direction, and preventing the powder shaking component 14 from swinging. It belongs to a consumable part. Further, the driving machine 11 drives the powder shaking component 14 to move vertically up and down. The vertical movement has the least resistance and can minimize the wear rate.

[0030] Further, the powder shaking component 14 includes a material pushing rod 141 and a powder shaking member 142. The powder shaking member 142 is arranged at the lower end of the material pushing rod 141. The upper end of the material pushing rod 141 passes through the cover plate 12 and the guiding component 15 and is assembled and connected to the output end of the driving machine 11. In the present invention, the powder shaking mechanism is integrally arranged. The cover plate 12 is detachably fixedly connected above the hopper 2 by means of connection such as bolts. When maintaining the equipment, only the connection between the cover plate 12 and the hopper 2 needs to be removed, so that quick disassembly and assembly can be realized, time and labor are saved, the convenience and timeliness of maintenance work are ensured, and the production efficiency is improved. Moreover, in the present invention, the driving machine 11 and the powder shaking component 14 are arranged vertically, with small resistance, and the position of the driving machine 11 is fixed without swinging, which greatly reduces the damage frequency of the driving machine, effectively ensures the service life of the components, effectively reduces the maintenance time and maintenance cost, and further improves the production efficiency. Not only that, the feeding pipe 13 of the present invention sinks into the hopper 2 and adopts the up-and-down material pushing mode, so that the powder adhering to the material pushing rod 141 is not easy to accumulate on the surface of the material pushing rod 141, and the wear rate of the movable connection part (i.e., the guiding component 15) between the material pushing rod 141 and the cover plate 12 is also small. Therefore, the material pushing rod 141 is not easy to bring the powder out of the hopper 2 during the up-and-down reciprocating movement, effectively solving the problem of powder leakage and material leakage, further reducing the maintenance frequency and maintenance cost, and thus further effectively improving the production efficiency.

[0031] Preferably, the powder shaking member 142 includes a cutting plate 1421. A plurality of spaced inclined pieces 1422 are arranged on one side of the cutting plate 1421. The upper ends of the inclined pieces 1422 are fixedly connected to the upper end of the cutting plate 1421. The inclined pieces 1422 and the cutting plate 1421 have a preset included angle and their openings face downward. Specifically, the cutting plate 1421 is vertically arranged, and the included angle between the cutting plate 1421 and the inclined pieces 1422 is 25-85 degrees. Preferably, in this embodiment, it is 45 degrees. Through the cooperation of the cutting plate 1421 and the plurality of spaced inclined pieces 1422, the present invention has small powder pushing resistance and high dispersing efficiency, making the discharging more uniform. Specifically, the lower end of the material pushing rod 141 is fixedly connected to the middle of the cutting plate 1421. More specifically, a reinforcing rib 1423 is also arranged at the connection part between the material pushing rod 141 and the powder shaking member 142.

[0032] Preferably, an auxiliary rod 1411 is provided at the upper end of the pushing rod 141. The auxiliary rod 1411 is parallel to the pushing rod 141 and fixedly connected to the pushing rod 141 through a limiting block 1412. The limiting block 1412 is located below the cover plate 12. Correspondingly, the guiding member 15 is a guiding sleeve, and there are two guiding sleeves 15, which are respectively sleeved on the pushing rod 141 and the auxiliary rod 1411 in a one-to-one correspondence. The double-rod fixation can further prevent swinging, further reduce wear, and improve the service life of components. Preferably, the driving machine 11 is a cylinder. Further, the powder shaking mechanism 1 further includes a bracket 16. The bracket 16 is fixed on the cover plate 12, and the cylinder is installed on the bracket 16. The output end of the cylinder points downward to drive the powder shaking member 14 to move vertically up and down.

[0033] Please continue to refer to Figure 1 , the blanking die 3 of the powder packaging machine for desiccant packaging provided by the present invention includes a feeding component 31 and a discharging component 32. The feeding component 31 includes a feeding hopper 33. An inlet 34 is provided at the upper end of the feeding hopper 33, and a plurality of blanking pipes 35 are provided below the feeding hopper 33. The discharging component 32 includes a discharging plate 38 and discharging pipes 36 provided in one-to-one correspondence with the blanking pipes 35. The discharging pipes 36 are penetratively provided on the discharging plate 38. In this embodiment, there are 4 discharging pipes 6.

[0034] As Figure 4 , Figure 5 and Figure 6As shown, in another embodiment of the blanking die 3 of the present invention, a flange 37 is provided in the middle of the discharge pipe 36. The discharge pipe 36 is installed on the discharge plate 38 through the flange 37, and the flange 37 is located above the discharge plate 38. Further, the discharge pipe 36 includes a material receiving portion 39 provided at the upper part and a discharge portion 310 provided at the lower part. The upper port of the material receiving portion 39 wraps the lower port of the blanking pipe 36. Further, the flange 37 is fixed to the discharge plate 38 by screws. Further, the material receiving portion 39, the discharge portion 310 and the flange 37 are integrally formed by welding. Further, the discharge plate 37 is an aluminum plate, and the aluminum plate has a high thermal conductivity, which is conducive to rapid heat conduction. Further, the discharge portion 310 is in a funnel shape to facilitate insertion into the film bag for powder injection. Specifically, a plurality of blanking pipes 35 and discharge pipes 36 are arranged in a row and evenly arranged to facilitate batch feeding production and improve production efficiency. The blanking die 3 of the present invention has a simple structure and can batch inject powder into the film bag for packaging at the same time, which is conducive to improving production efficiency. Moreover, the upper end of the discharge pipe 36 of the present invention wraps the lower end of the blanking pipe 35, effectively avoiding the occurrence of dusting, thereby avoiding the situation of excessive dust accumulation on the equipment surface and endangering the health of the staff. In addition, the discharge pipe 36 of the present invention is fixed on the discharge plate 38 through the flange 37, and the flange 37 is fixed above the discharge plate 38 by screws, effectively avoiding the risk that when the screws become loose, it is not easy to find due to the blocked sight and the screws fall into the powder bag, resulting in damage to the packaging die.

[0035] Further, the feeding component 31 further includes a plurality of blanking screws 311 corresponding to the blanking pipes 35 one by one. The blanking screws 311 are movably installed on the feeding hopper and introduce the powder from the blanking pipe 35 into the discharge pipe 36. The lower end of the blanking screw 311 is inserted into the blanking pipe 35. The blanking screw 311 is rotatably installed in the feeding hopper 33. Each time the blanking screw 311 moves (rotates), the powder will be quantitatively introduced from the blanking pipe 35 into the discharge pipe 36 to achieve accurate discharging (the amount of discharged material is determined by the number of rotation turns). Specifically, in the present invention, the spiral feeding component 7 drives the blanking screw 311 to rotate. The spiral feeding component 7 includes a discharge motor (a servo motor can be selected), a lead screw, and discharge gears (which can be referred to in FIG. 1, but not labeled in the figure). The discharge gears are multiple and correspond to the blanking screws 311 one by one. The discharge motor drives the lead screw to rotate, and the lead screw meshes with the discharge gears. When the lead screw rotates, it drives all the discharge gears to rotate simultaneously, that is, drives the blanking screws 311 to feed and supply materials simultaneously, ensuring that the discharge amounts of each discharge pipe are the same.
