Description
Technical Field
[0001] The present invention relates to the technical field of automatic powder packaging equipment, in particular to a fully automatic powder packaging system. Background Art
[0002] Powders are dry blends made by mixing and dispersing powdered raw resin with additives such as plasticizers, stabilizers, and lubricants. Mechanical agitation is the primary method for achieving uniform physical distribution. These materials are widely used in plastics processing applications such as twin-screw extrusion and calendering. They offer advantages such as a short process flow and low production costs. However, they can suffer from process drawbacks such as limited dispersibility of additives and the generation of bubbles.
[0003] There are currently two methods for opening powder bags: one is to manually open the bag in a glove box, using a knife to cut the bag and then pour out the powder; the other is to semi-automatically use a conveyor belt, which requires manual intervention for cleaning and recycling. The above-mentioned existing bag opening process has the following drawbacks:
[0004] 1. Dust leakage: Manual bag breaking causes powder to fly (especially conductive materials), polluting the environment and endangering health.
[0005] 2. Low efficiency: The processing time of a single bag is more than 3 minutes, which cannot match the rhythm of modern production lines.
[0006] 3. Safety hazards: Flammable and explosive powders (such as battery positive electrode materials) may explode when exposed to air.
[0007] 4. Poor adaptability: sticky powder is easy to remain in the bag, and powder with poor fluidity needs to be patted repeatedly.
[0008] To this end, the present application proposes a fully automatic powder packaging system. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1-4 The present invention provides a technical solution: a fully automatic powder unpacking system, comprising a sealing shell 4, a sealing shell 2 5 fixedly mounted on the top of the sealing shell 4, and a sealed movable door 6 mounted on the outside of the sealing shell 1 4 and the outside of the sealing shell 2 5, the inner cavity of the sealing shell 2 5 is a sealing cavity 9, a bag holder 10 is mounted on the top of the inner wall of the sealing cavity 9, and a punching knife 11, a cross cutting knife 12 and a half cutting knife 13 are mounted on the bottom of the inner wall of the sealing cavity 9, the punching knife 11, the cross cutting knife 12 and the half cutting knife 13 are arranged in sequence from left to right, a mechanical arm clamp 14 is further mounted on the right side of the inner wall of the sealing cavity 9, an inclined shaft 22 is mounted on the mechanical arm clamp 14, a negative pressure dust suction fixture 16 is installed between the sealing shell 1 4 and the sealing shell 2 5, and a purge component is also arranged between the sealing shell 1 4 and the sealing shell 2 5, and a heat sealing machine 3 is commonly arranged on the outside of the sealing shell 1 4 and the sealing shell 2 5.
[0028] In this embodiment, when in use, the powder packaging bag is placed inside the sealed shell 2 5, and then a suitable bag breaking method is selected according to the characteristics of the powder. The bag breaking methods are provided by the punching knife 11, the cross cutting knife 12 and the half cutting knife 13 respectively. There are three bag breaking methods to choose from. When the punching knife 11 and the cross cutting knife 12 are used to break the bag, they can be driven directly. If the half cutting knife 13 needs to be selected to break the bag, the bag opening needs to be heat-sealed by the heat sealing machine 3, and then the mechanical arm clamp 14 and the tilting shaft 22 are used to clamp the packaging bag using the mechanical arm clamp 14, and the material is shaken after the bag is broken to cause all the powder to be discharged from the packaging bag and completely empty the adhesive powder. At the moment of breaking the bag, the purge component is used to blow dry gas into the sealed cavity 9, and then the dust is extracted along the negative pressure dust suction clamp 16 and transported to the next step for processing.
[0029] Among them, the bag breaking and powder transportation are carried out inside a fully enclosed space, which can effectively ensure zero dust leakage and isolate oxygen.
[0030] As an optional embodiment, the purge assembly includes a dry gas delivery pipe 17, which is fixedly installed on the sealed shell 1 4 and the sealed shell 2 5, and a dry gas conduit 18 is installed at the bottom of the dry gas delivery pipe 17. One end of the dry gas conduit 18 passes through the outer wall of the sealed shell 1 4 and is installed with a dry air generator 19.
[0031] In this embodiment, during use, a dry air generator 19 is used to generate dry gas, which flows into the sealed cavity 9 along the dry gas conduit 18 and the dry gas delivery pipe 17, then enters the inner cavity of the sealed shell 4 along the negative pressure dust collection fixture 16, and is transported to the outside by subsequent components. Injecting dry air into the bag can destroy the arch bridge effect of the powder and improve fluidity.
[0032] As an optional embodiment, a fixing bracket 20 is fixedly mounted on the outer wall of the dry air generator 19, and the fixing bracket 20 is fixedly connected to the outer wall of the sealing shell 4.
[0033] In this embodiment, when in use, the fixing frame 20 is used to achieve fixed installation between the dry air generator 19 and the outer wall of the sealed shell 4, ensuring the stable performance of the dry air generator 19 during subsequent operation.
[0034] As an optional embodiment, a partition 15 is fixedly installed in the inner cavity of the sealed shell 4, and the negative pressure dust collection fixture 16 and the dry gas delivery pipe 17 are respectively located on both sides of the partition 15.
[0035] In this embodiment, when in use, the partition 15 is used to separate the inner cavity space of the sealed shell 4 into two independent areas, which is convenient for the input of drying gas on the one hand and the discharge of powder on the other hand without interfering with each other, thereby realizing dual-channel transportation of gas and powder.
[0036] As an optional embodiment, a vibrating screen 21 is fixedly installed between the right side of the partition 15 and the right side of the inner wall of the sealing shell 4.
[0037] In this embodiment, when in use, the vibrating screen 21 is used to filter out lumps in the powder.
[0038] As an optional embodiment, a rack 2 is provided on the left side of the heat sealing machine 3 , and a six-axis robot 1 is provided in front of the rack 2 .
[0039] In this embodiment, when in use, the powder bags are placed on the rack 2. At the same time, the setting of the six-axis robot 1 can realize the function of transporting the powder bags. After the bags are broken, the empty powder bags can be taken out as garbage without the need for manual cleaning by staff.
[0040] As an optional embodiment, a connecting pipe 7 is installed on the right side of the sealing shell 4, and a buffer tank 8 is installed on one end of the connecting pipe 7.
[0041] In this embodiment, when in use, the powder after the bag is broken is transported to the inside of the buffer tank 8 through the connecting pipe 7 for subsequent processing.
[0042] Workflow:
[0043] a. Bag supply: Use the six-axis robot 1 to remove the packaging bag containing powder from the storage rack 2, and then place it inside the sealed shell 5, and fix the packaging bag with the bag holder 10;
[0044] b. Cleaning: Dry air is generated by the dry air generator 19. The dry air flows into the sealed cavity 9 along the dry air duct 18 and the dry air delivery pipe 17, and blows the surface of the packaging bag containing the powder. The residual dust is then sucked away by the negative pressure dust suction fixture 16.
[0045] c. Bag breaking: According to the characteristics of the powder, select the appropriate bag breaking method from the three methods: punching knife 11 piercing the bag bottom and the powder falling, heat sealing machine 3 sealing, cross cutting knife 12 cutting the bag bottom and half cutting knife 13 cutting the bag bottom and the powder falling, and mechanical arm gripper 14 shaking the material. The powder characteristics are divided into two types: fluidity and explosion-proof level.
[0046] d. Powder conveying: The powder is sucked into the inner cavity of the sealed shell 4 through the negative pressure dust suction fixture 16, and the agglomerates in the powder are screened by the vibrating screen 21. Then, the powder enters the buffer tank 8 along the connecting pipe 7, is weighed, and is loaded into the container.
[0047] e. Waste bag recovery: The gripper on the six-axis robot 1 removes the empty bag and transfers it to the recovery unit.
[0048] After the above process, the following beneficial effects can be produced:
[0049] The dust leakage rate is ≤1%, and the double blockade of the negative pressure dust suction fixture 16 and the sealed chamber 9 is used to physically isolate the dust escape path; the efficiency is improved by 200%, and the multi-mode bag breaking (punching / cutting / tilting) is targeted to adapt to different powders, and the single bag processing time is less than one minute; the explosion-proof safety is 100%, and the inert gas environment bag breaking is coordinated with the container conveying path to eliminate the risk of static spark ignition; the powder residue rate is 0.5%, and the dry air purge and bag tilting mechanism cooperate to forcibly clear the adhering powder.
[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
