These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1-Figure 5 As shown, the utility model provides a technical solution: a high-efficiency powder material conveying and dust removal device, including a conveying device body 1, a dust cover 2 is installed on the top of the conveying device body 1, the front end of the dust cover 2 is rotatably connected with a sealing door 3 through a rotating shaft, an observation window 22 is installed on the surface of the sealing door 3, U-shaped guide blocks 4 are installed on both sides of the inside of the dust cover 2, a movable frame 5 is slidably connected inside the U-shaped guide block 4, fixed piles 6 are installed around the top of the movable frame 5, and the fixed piles 6 are conical in shape, a control block 7 is installed on the top of the dust cover 2, a mounting block 8 is installed on the bottom of the control block 7, a cutting knife 9 is installed on the bottom of the mounting block 8 through bolts, and the dust cover 2 is provided with a dust cover 2. A boss 10 is installed on the top of the dust cover 2, and the number of bosses 10 is two. A travel rod 11 is installed on one side of the boss 10. A movable plate 12 is slidably connected to the surface of the travel rod 11. A limit rod 13 is installed on the side of the movable plate 12 close to the control block 7. A first limit hole 14 for use with the limit rod 13 is opened on the surface of the control block 7. A second limit hole 15 is opened on the surface of the control block 7. The second limit hole 15 is located at the bottom of the control block 7. The second limit hole 15 is used in conjunction with the limit rod 13. The user pulls out the movable frame 5 and penetrates the four corners of the bag containing the powdered material through the conical fixing pile 6, and fixes the bag on the movable frame 5. The hollow part of the bag is then moved, and the movable frame 5 is moved to the inside of the dust cover 2 and the sealing door 3 is closed. The movable plate 12 is controlled to disengage the limiting rod 13 from the inner diameter of the first limiting hole 14, and the limiting of the control block 7 is released. The control block 7 is observed through the observation window 22, and the mounting block 8 installed at the bottom of the control block 7 is controlled to move up and down, so that the cutting knife 9 is driven to cut the bag. The cutting knife 9 is designed as a double-edged tool, which can perform the cutting operation more easily. When the cutting knife 9 cuts the bag, the powdery material inside is discharged and enters the inside of the conveying device body 1 for conveying operation. When the cutting knife 9 cuts the bag, the powdery material inside is discharged and enters the inside of the conveying device body 1 for conveying operation. The control block 7 is moved upward to move the cutting knife 9 to the top of the inner cavity of the dust cover 2, and the position of the control block 7 is fixed by the cooperation of the limiting rod 13 and the second limiting hole 15, so as to facilitate the subsequent removal of the movable frame 5 and prevent the cutting knife 9 from being blocked. The dust cover 2 and the sealing door 3 are arranged to intercept dust, effectively preventing the dust from flying and reducing the harm to the health of the staff. The movable frame 5, the fixed pile 6 and the cutting knife 9 are used in cooperation to move the bag opening step to the inside of the dust cover 2, effectively preventing the dust from flying. At the same time, the fixing method of the bag by the fixed pile 6 is convenient for taking, so that the overall efficiency is more efficient.
[0022] Reference Figure 2 As shown, in the present embodiment: a baffle 23 is installed at one end of the travel rod 11 away from the boss 10, a limiting spring 24 is installed on the side of the movable plate 12 close to the baffle 23, and the end of the limiting spring 24 away from the movable plate 12 is fixedly connected to the baffle 23. When the limiting rod 13 is inserted into the first limiting hole 14 or the second limiting hole 15, the position of the movable plate 12 is limited by the limiting spring 24, thereby preventing the limiting rod 13 from being separated from the first limiting hole 14 or the second limiting hole 15. At the same time, the setting of the baffle 23 supports the limiting spring 24, so that the limiting spring 24 has a lever point and an installation point.
[0023] Reference Figure 5 As shown, in this embodiment: slide bars 16 are installed on both sides of the control block 7, and travel blocks 17 are installed on both sides of the inside of the dust cover 2. A U-shaped groove 18 for use with the slide bar 16 is opened on one side of the travel block 17. Through the sliding connection between the slide bar 16 and the U-shaped groove 18, the control block 7 is limited when it moves longitudinally to prevent the control block 7 from swinging.
[0024] Reference Figure 3 and Figure 4 As shown, in this embodiment: through grooves 19 are provided on both sides of the top of the movable frame 5, and a plurality of auxiliary wheels 20 are rotatably connected to the interior of the through grooves 19 through a rotating shaft, and guide rails 21 used in conjunction with the auxiliary wheels 20 are provided on the top and bottom of the U-shaped guide block 4. By using the auxiliary wheels 20 in conjunction with the guide rails 21, the friction resistance between the movable frame 5 and the U-shaped guide block 4 is reduced, so that the user can easily move the movable frame 5 after installing the bagged material through the fixed piles 6.
[0025] Working principle: the user pulls out the movable frame 5, and penetrates the four corners of the bag containing the powdered material through the conical fixing piles 6, and fixes the bag in the hollow part of the movable frame 5, and then moves the movable frame 5 to the inside of the dust cover 2 and closes the sealing door 3, and controls the movable plate 12 to disengage the limiting rod 13 from the inner diameter of the first limiting hole 14, releases the limit on the control block 7, and observes through the observation window 22, and controls the up and down movement of the control block 7 to make the mounting block 8 installed at the bottom of the control block 7 drive the cutting knife 9 to cut the bag, wherein the cutting knife 9 is designed as a double-edged tool, which can perform the cutting operation more easily, and the sliding connection between the sliding rod 16 and the U-shaped groove 18 plays a role in limiting the control block 7 when it moves longitudinally to prevent the control block 7 from swinging, and when the cutting knife 9 cuts the bag, the powdered material inside it is discharged and enters the inside of the conveying device body 1 for conveying The cutting knife 9 is moved to the top of the inner cavity of the dust cover 2 by moving the control block 7 upwards, and the position of the control block 7 is fixed by the cooperation of the limiting rod 13 and the second limiting hole 15, so as to facilitate the subsequent removal of the movable frame 5 and prevent the cutting knife 9 from being blocked. When the limiting rod 13 is inserted into the first limiting hole 14 or the second limiting hole 15, the position of the movable plate 12 is limited by the limiting spring 24, so as to prevent the limiting rod 13 from being separated from the first limiting hole 14 or the second limiting hole 15. At the same time, the setting of the baffle 23 supports the limiting spring 24, so that the limiting spring 24 has a lever point and an installation point. The auxiliary wheel 20 and the guide rail 21 are used in cooperation to reduce the friction resistance between the movable frame 5 and the U-shaped guide block 4, so that the user can still easily move the movable frame 5 after installing the bagged material through the fixed pile 6.
