[0027] See also Figure 1-7 The utility model provides a technical solution: a powder material ton bag quantitative packaging machine capable of preventing residual material from being adsorbed, comprising a frame 1 and a discharging valve 3, a silo 2 is installed above the frame 1, a feeding port 7 is connected to one side of the silo 2, a feeding pipe 4 is connected below the silo 2, the discharging valve 3 is installed inside the feeding pipe 4, a conveyor belt 5 is provided below the frame 1, a fixing frame 8 is fixed to the inner side of the frame 1 close to the feeding pipe 4, a second mounting plate 11 is provided above the fixing frame 8, and a second mounting plate 11 is provided above the fixing frame 8. A weighing sensor 10 is installed above the No. 2 mounting plate 11, and the feed pipe 4 passes through the middle of the No. 2 mounting plate 11 and the fixed frame 8. A scraper mechanism 6 is installed above the silo 2, and one side of the scraper mechanism 6 is located inside the silo 2. An adjusting mechanism No. 1 9 is installed inside the No. 2 mounting plate 11, and a No. 2 adjusting mechanism 13 and a No. 2 bidirectional screw rod 14 are provided on the inner side of the No. 1 adjusting mechanism 9, and the No. 2 adjusting mechanism 13 is connected to the No. 2 bidirectional screw rod 14, and a hook 12 is connected below the No. 2 adjusting mechanism 13.

[0028] according to Figure 1-3 As shown, the scraper mechanism 6 includes a scraper 601, a No. 1 mounting plate 602, a motor 603, a No. 1 gear 604, a No. 2 gear 605, a support spring 606 and a connecting frame 607. A No. 1 mounting plate 602 is provided inside the silo 2, a support spring 606 is provided in the built-in groove of the No. 1 mounting plate 602, connecting frames 607 are provided on both sides of the support spring 606, the connecting frame 607 and the No. 1 mounting plate 602 are slidably sleeved, a scraper 601 is fixed to one end of the connecting frame 607 close to the inner wall of the silo 2, one end of the No. 1 mounting plate 602 is connected to the No. 2 gear 605 through a rotating shaft, and the rotating shaft of the No. 1 mounting plate 602 is connected to the silo 2 through a bearing, one side of the No. 2 gear 605 is meshed with the No. 1 gear 604, one side of the No. 1 gear 604 is connected to the motor 603, and the number of the scraper 601 is two.

[0029] During specific implementation, since the powder may be damp and adsorbed on the inner wall of the silo 2, it is not convenient to clean and will cause waste of powder. During the powder packaging process, the motor 603 can be started to make the motor 603 drive the No. 1 gear 604 to rotate, and the No. 1 gear 604 then drives the No. 2 gear 605 to rotate, and the No. 2 gear 605 then drives the No. 1 mounting plate 602 to rotate. The rotation of the No. 1 mounting plate 602 will cause the connecting frame 607 to drive the scraper 601 to rotate and scrape off the residual powder adsorbed on the inner wall of the silo 2. At the same time, the supporting spring 606 pushes the connecting frame 607 to both sides, which can support the connecting frame 607 so that the connecting frame 607 drives the scraper 601 to always fit with the inner wall of the silo 2, thereby improving the scraping efficiency. The residual powder on the inner wall of the silo 2 is scraped off by the scraper 601, which is convenient for subsequent cleaning, reduces the waste of powder, and improves the practicality of the powder ton bag quantitative packaging machine.

[0030] according to Figure 1-2 and Figure 5-6 As shown, the No. 1 adjustment mechanism 9 includes a moving frame 901, a No. 1 bidirectional screw rod 902, a slide bar 903 and a rotating handle 904. The No. 1 bidirectional screw rod 902 is installed inside the No. 2 mounting plate 11 through a bearing. The slide bar 903 is fixed to the inner side of the No. 2 mounting plate 11 away from the No. 1 bidirectional screw rod 902. The outer sides of the No. 1 bidirectional screw rod 902 and the slide bar 903 are sleeved with the moving frame 901. One end of the No. 1 bidirectional screw rod 902 is fixedly connected to the rotating handle 904. The No. 2 adjustment mechanism 13 includes a slider 131, a knob 132, a No. 3 gear 133 and a No. 4 gear 134. The second bidirectional screw rod 14 is installed on the inner side of the movable frame 901 through a bearing, and one end of the second bidirectional screw rod 14 is fixedly sleeved with a fourth gear 134, and one side of the fourth gear 134 is meshed with a third gear 133, and one side of the third gear 133 is connected to a knob 132 through a transmission shaft, and the outer side of the second bidirectional screw rod 14 is threadedly sleeved with a slider 131, and the lower side of the slider 131 is connected to the hook 12, one end of the movable frame 901 is threadedly sleeved with the first bidirectional screw rod 902, and the other end of the movable frame 901 is slidably sleeved with the slide rod 903.

[0031] In specific implementation, the position of the hook 12 of most powder bulk quantitative packaging machines is fixed or inconvenient to adjust, resulting in the inability to adapt to packaging bags of different sizes. When the position of the hook 12 needs to be adjusted according to the size of the packaging bag, the handle 904 can be rotated to drive the No. 1 bidirectional screw rod 902 to rotate, and then one end of the moving frame 901 moves closer to or away from each other on the No. 1 bidirectional screw rod 902, and the other end of the moving frame 901 slides on the slide bar 903, and the slide bar 903 guides the moving block 901. After the movable frame 901 is adjusted to the appropriate position, the knob 132 is rotated to drive the third gear 133 to rotate, and the third gear 133 drives the fourth gear 134 to rotate, and then the fourth gear 134 drives the second bidirectional screw rod 14 to rotate, so that the slider 131 drives the hook 12 on the second bidirectional screw rod 14 to move closer to or away from each other. By changing the position of the movable frame 901 and the slider 131, the position of the hook 12 can be quickly adjusted to adapt to packaging bags of different sizes, thereby improving the convenience of the powder bulk quantitative packaging machine.

[0032] Working principle: When using this powder bulk quantitative packaging machine that can prevent residual material from being adsorbed, first, adjust the position of the hook 12 through the No. 1 adjustment mechanism 9 and the No. 2 adjustment mechanism 13 to adapt to the size of the packaging bag, then manually hang the draw ropes at the four corners of the packaging bag on the hook 12, and then start the discharge valve 3 to discharge the powder in the silo 2, and the powder falls into the packaging bag. At the same time, the weighing sensor 10 senses the downward pressure of the No. 2 mounting plate 11, which can sense the weight of the powder and enable the powder to be quantitatively packaged. During the discharge process, the powder adsorbed on the inner wall of the silo 2 can be scraped off by the scraper mechanism 6, which is convenient for subsequent cleaning and reduces powder waste. After the powder is packaged, it is transported by the conveyor belt 5. The scraper mechanism 6, the No. 1 adjustment mechanism 9 and the No. 2 adjustment mechanism 13 improve the practicality and convenience of the powder bulk quantitative packaging machine.
