[0002] Powder packaging is widely used in many industries such as chemical industry, food, medicine, building materials, etc. Accurate, efficient and hygienic packaging of powder materials is an important part of the production process. Powders are packaged in bags by installing machines, but the existing powder packaging machines still have some shortcomings during use.

[0003] The prior art (application number: 202311028505.4, Chinese patent with application date of 2023-08-16) discloses a powder automatic quantitative servo weighing packaging machine and a feeding weighing control method, which relates to the field of servo weighing packaging machines. A speed regulating hopper is fixedly installed on the support top plate, a servo motor is arranged on one side of the speed regulating hopper, a feeding electric control valve is arranged in the speed regulating hopper, the servo motor drives and connects the feeding electric control valve, a bag clamping feeding bin is arranged below the support top plate, and the support top plate is arranged with a plurality of weighing unit components for sensing and detecting the downward force of the bag clamping feeding bin. A group of bag clamping arms are arranged on both sides of the bag clamping feeding bin, a cylinder assembly is arranged between the two bag clamping arms in the same group, and the lower ends of the two bag clamping arms in the same group are equipped with bag clamping plates that cooperate with each other. When the weighed weight meets the standard, the final excess weight of the material in the bag is small, so that continuous and high-precision feeding weighing control is achieved while ensuring the control of the loading rate; the prior art (application number: 20 2222627426.2, Chinese patent application date is 2022-10-07) discloses a composite flocculant packaging machine, which relates to the field of composite flocculant packaging technology, including a packaging machine body installed on the top of the base, a control end installed on one side of the packaging machine body, a feeding hopper installed on the top of the packaging machine body, and a feeding pipe installed at the bottom of the feeding hopper. Through the operation of the second cylinder, the bag mouth can be moved to the bottom end of the feeding pipe. Through the action of the first cylinder, the clamping plate can pass through the through groove to clamp the bag mouth, so as to facilitate feeding. After the feeding is completed, through the operation of the servo motor, the packaging bag containing the composite flocculant can be moved to one side through the mounting plate and the threaded pipe to prevent manual handling by personnel, thereby preventing dust from being inhaled by personnel and causing certain impacts on the health of personnel. At the same time, after the packaging bag containing the composite flocculant is removed, the packaging bag that does not contain the composite flocculant on the other side of the top of the connecting plate will be moved to the bottom end of the feeding pipe for loading.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 3 As shown, the existing powder packaging machine can only clamp and seal the bag mouth during the packaging process, but it is inconvenient to expand and fix the bag body before unloading, so that the bag body filling space is limited, the powder cannot be fully filled, and the upper end of the powder is too close to the bag mouth, which affects the subsequent packaging. In order to solve this technical problem, this embodiment discloses the following technical content: an anti-spillage environmentally friendly powder packaging machine, including a machine base 1 installed in a workshop, a hopper 3 is fixedly installed on the upper end of the machine base 1, and a fixed material pipe 4 is fixedly connected to the lower end of the hopper 3; The lower end of the fixed material pipe 4 is connected to the movable material pipe 8 through the telescopic tube 7, and the first frame 5 and the second frame 6 are fixedly installed on the inner side of the machine base 1, and the first frame 5 is fixedly installed with an electric telescopic rod 9, and the output end of the electric telescopic rod 9 is fixedly connected with a first movable plate 10, and at the same time, the lower part of the first movable plate 10 is elastically connected with a second movable plate 11, and the lower surface of the first movable plate 10 is elastically rotatably installed with a clamping member 14 for clamping the bag mouth, and an air supply component for preventing powder from spilling is connected between the first movable plate 10 and the second movable plate 11.

[0022] A conveyor 2 for conveying bags is installed on the machine base 1 , and the conveyor 2 evenly conveys vertically placed open bags, and the bags are transported to just below the movable material pipe 8 through the conveyor 2 .

[0023] A spring 12 is fixedly connected between the first movable plate 10 and the second movable plate 11, and the electric telescopic rod 9 drives the second movable plate 11 to move downward synchronously when pushing the first movable plate 10 downward, and the second movable plate 11 is fixedly connected to the outer side of the movable material tube 8, and the first movable plate 10 is slidably sleeved on the outer sides of the telescopic tube 7 and the movable material tube 8.

[0024] A pull rope 15 is wound around the shaft of the clamp 14, and the upper end of the pull rope 15 is fixedly connected to the outer side of the first frame 5. During the downward movement of the second movable plate 11, the pull rope 15 pulls the clamp 14 to elastically rotate. During the rotation of the clamp 14, the movable material tube 8 is cooperated to clamp and seal the bag opening.

[0025] A vertically arranged guide column 13 is symmetrically fixedly installed on the second movable plate 11, and the guide column 13 slides through the first movable plate 10. The air delivery component includes an elastic capsule 17 sleeved on the outside of the guide column 13, and the elastic capsule 17 is fixedly connected between the first movable plate 10 and the second movable plate 11, and the elastic capsule 17 is squeezed and stretched during the relative movement of the first movable plate 10 and the second movable plate 11.

[0027] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. After the existing powder packaging machine is unloaded, the powder is easy to float near the bag mouth, which is easy to cause the powder to spill, thereby affecting the processing environment. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 4-Figure 8As shown; a filter assembly for filtering out recovered powder is fixedly mounted on the first frame 5, and a knocking piece 25 for knocking the movable material pipe 8 is also mounted on the first movable plate 10, the filter assembly includes a filter cartridge 21 fixedly mounted on the first frame 5, and a filter screen 22 is mounted on the inner side of the filter cartridge 21, and the lower end of the filter cartridge 21 is connected to the suction pipe 18, and a purification pipe 23 is connected between the upper end of the filter cartridge 21 and the fixed material pipe 4, and the knocking piece 25 and the second movable plate 11 are elastically connected. The first movable plate 10 and the second movable plate 11 are connected in a rotatable manner, and the striking end of the striking piece 25 is initially attached to the outer side of the movable material tube 8, and a magnetic sheet 26 is fixedly installed on the outer side of the striking piece 25, and a magnetic block 24 is fixedly installed on the lower end of the first movable plate 10, and when the first movable plate 10 and the second movable plate 11 are close to each other, the magnetic block 24 is close to the magnetic sheet 26, and the magnetic poles of the opposite surfaces of the magnetic block 24 and the magnetic sheet 26 are the same, and at the same time, the striking piece 25 elastically rotates under the magnetic force of both the magnetic block 24 and the magnetic sheet 26.

[0028] By adopting the above technical solution, when the powder filling is completed, the electric telescopic rod 9 is controlled to drive the first movable plate 10 to move upward. At this time, the first movable plate 10 and the second movable plate 11 will stretch the elastic capsule 17, so that it can extract the air in the filter cartridge 21 through the suction pipe 18, so that the filter cartridge 21 can extract the powder near the lower end of the movable material pipe 8 and the bag mouth of the packaging bag through the purification pipe 23. At this time, the bag mouth of the packaging bag is automatically attached due to the reduction of air pressure, thereby effectively reducing the powder. When the first movable plate 10 and the second movable plate 11 are close to each other, the magnetic block 24 will gradually approach the magnetic sheet 26 outside the knocking piece 25, so that the knocking piece 25 will elastically rotate under the action of the magnetic force. When the first movable plate 10 moves up, the knocking piece 25 will lose the magnetic effect and elastically rotate, so that the knocking piece 25 can knock and vibrate the movable material tube 8, thereby promoting the discharge of the residual powder attached to the inner wall of the movable material tube 8, so as to facilitate the treatment together with the powder spilled in the packaging bag.
