Description

Technical Field

[0001] The utility model relates to the technical field of powder material processing, in particular to a weighing device for powder material. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Powder coating is completely different from general coating in form. It exists in the state of fine powder. Since no solvent is used, it is called powder coating. The main characteristics of powder coating are: harmless, efficient, resource-saving and environmentally friendly.

[0003] A Chinese patent discloses a weighing device for powder material production, with the authorization announcement number CN218877651U. The patented technology weighs the flour entering the flour bag through the mutual cooperation of the weighing device and other components. There is no need to set up other weighing stations, reducing the number of circulating stations, thereby helping to improve work efficiency. By setting up components such as a card plate, it is more convenient to install the dust bag on the dust suction pipe or remove it from the dust suction pipe, reducing the burden on the personnel who replace the dust bag, increasing the replacement speed, and helping to increase production.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: after the existing powder material weighing device weighs the powder coating, since the powder coating is relatively fine and easily penetrates the packaging bag and remains on the surface of the weighing pan, it is inconvenient for the staff to clean and collect the weighed powder coating, resulting in a small amount of powder coating remaining on the surface of the weighing device, reducing the accuracy of the powder coating after weighing. At the same time, the residual powder coating is easy to cause pollution to the next coating weighing, affecting the original color of the coating. Utility Model Content

[0024] Reference Figure 2 and Figure 3As shown, in the present embodiment: a circular groove 10 is opened inside the slide bar 5, and a plurality of balls 11 are slidably connected to the inner wall of the circular groove 10, and the surface of the balls 11 is slidably connected to the surface of the slide bar 5. When the staff pulls the slider 6 to move on the surface of the slide bar 5, the plurality of balls 11 rolling on the inner wall of the circular groove 10 are slidably connected to the surface of the slide bar 5, thereby reducing the contact area between the slider 6 and the slide bar 5, and reducing the friction resistance generated by the slider 6 sliding on the surface of the slide bar 5, so that the slider 6 slides more smoothly on the surface of the slide bar 5, and it is more convenient for the staff to pull the slider 6 to move on the surface of the slide bar 5.

[0025] Reference Figure 2 and Figure 3 As shown, in the present embodiment: the surface of the slide bar 5 is slidably connected with a first spring 12, one end of the first spring 12 is fixedly connected to the slider 6, and the end of the first spring 12 away from the slider 6 is fixedly connected to the L-shaped plate 4. When the staff pulls the handle 8 to drive the scraper 7 to move the slider 6 on the surface of the slide bar 5, the slider 6 moves and pulls the first spring 12 to extend to accumulate force. When the staff releases the control of the scraper 7, the first spring 12 releases the force generated, pulls the slider 6 to drive the scraper 7 to rebound to reset the position of the scraper 7, and moves the scraper 7 to one side of the weighing device body 1, so that the staff can use the scraper 7 to clean the powdered coating into the collection box 9 next time.

[0026] Reference Figure 2 and Figure 3 As shown, in the present embodiment, one side of the scraper 7 is fixedly connected with an extension plate 13, and a brush 14 is installed at the bottom of the extension plate 13. When the staff uses the scraper 7 to move the top of the weighing pan 2, the scraper 7 moves and drives the extension plate 13 to move, so that the brush 14 at the bottom of the extension plate 13 cleans the top of the weighing pan 2, preventing a small amount of powdered paint after weighing from remaining on the surface of the weighing pan 2 and causing the powdered paint to be weighed next time to mix with it, and preventing the color of the powdered paint from being mixed with the residual paint pigment to affect the original color of the paint.

[0027] Reference Figure 4 and Figure 5As shown, in the present embodiment: a mounting shell 15 is fixedly connected to one side of the weighing device body 1, a T-shaped rod 16 is fixedly connected to the bottom end of the mounting shell 15, a limiting rod 17 is slidably connected to the surface of the T-shaped rod 16, a second spring 18 is fixedly connected to the bottom of the limiting rod 17, and the bottom of the second spring 18 is fixedly connected to the bottom end of the mounting shell 15. The staff pushes the limiting rod 17 downward to press the second spring 18 to store force, so that the limiting rod 17 is placed on the inner wall of the mounting shell 15, so that the top of the limiting rod 17 no longer abuts against one side of the scraper 7, and the constraint of the limiting rod 17 on the scraper 7 is released, so that the scraper 7 can move on the surface of the weighing pan 2, and when the staff loosens the limiting rod 17, the T-shaped rod 16 releases the force generated, pushing the limiting rod 17 to rebound upward and reset, thereby limiting the position of the scraper 7.

[0028] Reference Figure 4 and Figure 5 As shown, in this embodiment: the T-shaped rod 16 is placed on the inner wall of the second spring 18, and the surface of the second spring 18 is slidably connected to the surface of the T-shaped rod 16. When the limiting rod 17 pushes the second spring 18 to compress and accumulate force, the second spring 18 is tightly attached to the surface of the T-shaped rod 16 when moving, preventing the second spring 18 from curling up when rebounding and causing entanglement to affect the normal operation of the component.

[0029] Reference Figure 1 As shown, in this embodiment: a rounded corner 19 is provided on one side of the weighing pan 2 close to the collecting box 9. By providing the rounded corner 19 on one side of the weighing pan 2, the powdered coating pushed by the scraper 7 on the surface of the weighing pan 2 can flow downward more smoothly into the collecting box 9 through the arc design of the rounded corner 19.

[0030] Reference Figure 1 and Figure 2 As shown, in this embodiment: the scraper 7 is in a U-shaped structure, and the bottom is designed with a sharp corner. The scraper 7 designed with a U-shaped structure allows the U-shaped structure to wrap the powdered coating when the scraper 7 scrapes the powdered coating, thereby improving the scraping effect of the scraper 7 on the powdered coating and preventing the powdered coating from flowing out to both sides when pushed by the scraper 7 and causing spillage.

[0031] Working principle: The staff pulls the handle 8 to drive the scraper 7 so that the slider 6 moves left and right on the surface of the slide bar 5, so that the bottom of the scraper 7 moves close to the top of the scale pan 2, and the weighed powdered paint on the top of the scale pan 2 is pushed and scraped to the collection box 9, which is convenient for the staff to collect the weighed powdered paint on the top of the scale pan 2, and prevents the staff from manually taking the weighed powdered paint and causing part of the powdered paint to remain on the surface of the scale pan 2, reducing the residual waste caused by the staff weighing the powdered paint, reducing the residual error caused by the weighing of the powdered paint, improving the accuracy of the device for weighing the powdered paint, and facilitating the staff to collect the weighed powdered paint. When the staff pulls the slider 6 to move on the surface of the slide bar 5, a number of particles rolling on the inner wall of the circular groove 10 are The balls 11 are slidably connected with the surface of the slide bar 5, reducing the contact area between the slide bar 6 and the slide bar 5, reducing the friction resistance generated by the slide bar 6 sliding on the surface of the slide bar 5, making the slide bar 6 slide more smoothly on the surface of the slide bar 5, and making it easier for the staff to pull the slide bar 6 to move on the surface of the slide bar 5. When the staff pulls the handle 8 to drive the scraper 7 to move the slide bar 6 on the surface of the slide bar 5, the slide bar 6 moves and at the same time pulls the first spring 12 to extend and store force. When the staff releases the control of the scraper 7, the first spring 12 releases the force generated, pulls the slide bar 6 to drive the scraper 7 to rebound to reset the position of the scraper 7, and moves the scraper 7 to one side of the weighing device body 1, so that the staff can use the scraper 7 to clean the powdered paint into the collection box 9 next time. When the scraper 7 is used to move the top of the scale pan 2, the scraper 7 drives the extension plate 13 to move while moving, so that the brush 14 at the bottom of the extension plate 13 cleans the top of the scale pan 2 to prevent a small amount of powdered paint from remaining on the surface of the scale pan 2 after weighing, causing the powdered paint to be mixed with it for the next weighing, and preventing the color of the powdered paint from being mixed with the residual paint pigment and affecting the original color of the paint. The staff pushes the limit rod 17 downward to press the second spring 18 to store force, so that the limit rod 17 is placed on the inner wall of the mounting shell 15, so that the top of the limit rod 17 no longer abuts against one side of the scraper 7, and the limit rod 17 is released from the constraint of the scraper 7, so that the scraper 7 can move on the surface of the scale pan 2. When the staff loosens the limit rod 17, the T-bar 16 The force generated by releasing the limit rod 17 rebounds upward and resets, limiting the position of the scraper 7. When the limit rod 17 pushes the second spring 18 to compress and accumulate force, the second spring 18 is close to the surface of the T-shaped rod 16 when moving, preventing the second spring 18 from curling and causing entanglement when rebounding, affecting the normal operation of the component. By opening one side of the scale pan 2 into a rounded corner 19, the powdered paint pushed by the scraper 7 on the surface of the scale pan 2 can flow downward more smoothly into the collection box 9 through the arc design of the rounded corner 19. The scraper 7 with a U-shaped structure can wrap the powdered paint when the scraper 7 scrapes the powdered paint, thereby improving the scraping effect of the scraper 7 on the powdered paint and preventing the powdered paint from flowing out to both sides when pushed by the scraper 7 and causing spillage.
