Description

Technical Field

[0001] This utility model relates to the field of automatic weighing device technology, and in particular to an automatic weighing device for powder coatings. Background Technology

[0002] Automatic weighing devices for powder coatings are specialized automated equipment used in the production, distribution, and use of powder coatings. In order to accurately measure the weight of powder coatings, precise weighing can complete the weighing task of powder coatings more quickly and accurately, ensuring the correct coating ratio in production and avoiding product quality being affected by excessive or insufficient coating.

[0003] In existing technologies, some automatic weighing devices for powder coatings first transport the powder coating to a weighing container or platform via a conveying device. The weight of the coating is monitored in real time by sensors. When the coating reaches the predetermined weight, the system can automatically stop feeding and transport the weighed coating to the next process or packaging container. However, some automatic weighing devices for powder coatings require manual operation to align the bag with the discharge port and allow the powder coating to enter the bag. Prolonged manual operation can lead to situations where the bag is not accurately aligned with the discharge port, resulting in the powder coating falling outside and being wasted. Utility Model Content

[0004] This invention proposes an automatic weighing device for powder coatings, aiming to improve upon the problem in some existing automatic weighing devices for powder coatings where prolonged manual operation leads to bags not being accurately aligned with the discharge port, resulting in waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic weighing device for powder coatings includes a weighing body. A slide plate is fixedly connected to the top of the weighing body. A telescopic assembly for providing power to drive an automatic gripper to slide is fixedly connected to the top of the weighing body. An automatic gripper is fixedly connected to the outside of the telescopic assembly. The automatic gripper is fitted with two telescopic rods, one end of which is fitted with a clamping block. A second cylinder is slidably connected to the outside of the automatic gripper. A lifting rod is fitted to the driving end of the second cylinder. A bag opener is slidably connected to the outside of the automatic gripper. Opposing telescopic rods are fitted inside the bag opener. One end of each telescopic rod is fitted with an insert rod. A hinge is fixedly connected to the outside of one end of the slide plate. A stop block is fixedly connected to the outside of one end of the slide plate. A rotating plate is fixedly connected to the bottom of one end of the hinge. An insert rod is fixedly connected to the outside of the rotating plate. A fixed plate is fixedly connected to one end of the rotating plate. A plurality of rotating assemblies for rotating partitions are fixedly connected to one end of the fixed plate.

[0007] The main support components of the weighing device are used in conjunction with the weighing platform to weigh the bags containing powder coating. The slide plate is provided with a slide rail to guide the telescopic component to slide with the automatic clamp. The automatic clamp is controlled by the control terminal through electronic signals to provide power, which drives the internal opposing telescopic rod to extend and retract, thereby driving the bag to slide to the bottom of the discharge cylinder. The cylinder is controlled by the control terminal through electronic signals to provide power, which drives the lifting rod to rise and fall, thereby driving the bag opener (7) to rise and fall, so that the insertion rod of the bag opener (7) can be inserted into the bag. The bag opener (7) is controlled by the control terminal through electronic signals to provide power, which drives the telescopic rod to extend and retract, thereby driving the insertion rod to move outward to achieve the effect of opening the bag. The hinge allows the rotating plate to rotate, which makes it convenient to insert the bag into the insertion rod. At the same time, the stop block can block the rotating plate to prevent it from rotating after reaching a certain angle. The fixed plate is connected to a rotating component that allows the partition to rotate. The rotating component allows the partition to rotate, avoiding the partition being fixed and affecting the bag opener's gripping of the bag.

[0008] As a further description of the above technical solution:

[0009] The telescopic assembly includes a cylinder, the drive end of which is fixedly connected to a telescopic rod, and the bottom of the cylinder is fixedly connected to the top of the slide plate.

[0010] The cylinder provides power to extend and retract the telescopic rod, which in turn drives the automatic gripper to slide.

[0012] The rotating assembly includes a cylindrical connecting block, a second rotating shaft is rotatably connected to the inner wall of the cylindrical connecting block, a partition is fixedly connected to the outside of the second rotating shaft, and the outside of the cylindrical connecting block is fixedly connected to the top and bottom of the fixed plate.

[0013] The cylindrical connecting block, in conjunction with the rotating shaft, forms a hinge effect, allowing the partition to rotate.

[0014] As a further description of the above technical solution:

[0015] A cylinder three is fixedly connected to the top of the weighing device body. A telescopic rod two is fixedly connected to the drive end of the cylinder three. A fixed circular belt two is fixedly connected to the outside of the telescopic rod two. A frustum loading cylinder is slidably connected to the inner wall of the fixed circular belt two. A feed pipe is fixedly connected to the top of the frustum loading cylinder. A motor one is fixedly connected to the top of the frustum loading cylinder. A discharge cylinder is fixedly connected to the bottom of the frustum loading cylinder.

[0016] Cylinder three provides power to drive telescopic rod two to extend and retract, thereby driving fixed circular belt two to extend and retract, adjusting the height of the truncated cone loading cylinder. The feed pipe loads the powder coating into the truncated cone loading cylinder. The motor provides power, and the discharge cylinder is the outlet for the powder coating inside the truncated cone loading cylinder to fall out.

[0017] As a further description of the above technical solution:

[0018] The drive end of the motor is fixedly connected to a rotating shaft, and a plurality of connecting rods are fixedly connected to the outside of the rotating shaft. A stirring blade is fixedly connected to the outside of the plurality of connecting rods.

[0019] The motor provides power to drive the rotating shaft to rotate, which in turn drives the stirring blades connected to the connecting rod to stir the powder coating and prevent the powder coating from clogging.

[0020] As a further description of the above technical solution:

[0021] A second motor is fixedly connected to the outside of the discharge cylinder. A second rotating shaft is fixedly connected to the drive end of the second motor. A closing and opening plate is fixedly connected to the outside of the second rotating shaft. A U-shaped placement rod is fixedly connected to the outside of the discharge cylinder. A fixing plate is fixedly connected to one end of the U-shaped placement rod.

[0022] Motor 2 provides power to drive rotating shaft 2 to rotate, which in turn drives the closed opening and closing plate to rotate, thereby controlling the powder coating to fall from the discharge cylinder. The U-shaped placement rod is used to fix the discharge cylinder.

[0023] As a further description of the above technical solution:

[0024] The U-shaped placement rod is rotatably connected to a rotating rod three. A connecting rod two is fixedly connected to one side of the rotating rod three. A cylinder three is fixedly connected to the outside of the rotating rod three. A telescopic rod three is fixedly connected to the drive end of the cylinder three. A clamping plate is fixedly connected to the bottom of the rotating rod three.

[0025] Rotating rod three is rotatably connected to the U-shaped placement rod. The left and right rotating rods three are connected by connecting rod two. The two reverse cylinders three drive the telescopic rod three to extend and retract, thereby driving the rotating rod three to rotate, so that the clamp can clamp the bag at the bottom of the discharge cylinder.

[0028] The weighing platform is used to place bags containing powder coatings to be weighed. The system provides power to control the rotation of the rotating shaft three, which in turn rotates the rollers, removing the weighed bags. The control terminal uses electronic signals to control the automatic gripper, cylinder two, and bag opener. The automatic gripper clamps the bag, and cylinder two drives the bag opener to rise and fall, allowing the insert rod of the bag opener to be inserted into the bag. Controlling the insert rod to move outwards expands the bag.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the bags containing powder coating are inserted into the insert rods at both ends and separated by partitions to facilitate clamping by the lower cylinder two. At the same time, the two cylinders one are activated, driving the telescopic rod one to extend and retract, thereby driving the automatic clamp to slide and move to the two ends of the bag to clamp the bag. The bag is clamped to the bottom of the discharge cylinder, and the cylinder two drives the bag opener above to rise and fall, so that the insert rod of the bag opener pulls the bag open and aligns it with the rotating shaft two, which facilitates the loading and weighing of materials, reduces long-term manual operation, and ensures that the bag is accurately aligned with the discharge port.

[0031] 2. In this utility model, the starting motor drives the rotating shaft to rotate, thereby causing the rotating shaft to rotate through the stirring blades, which stirs the powder coating in the frustum loading cylinder, avoiding the risk of blockage. At the same time, the starting motor drives the rotating shaft to rotate, thereby causing the closing plate to rotate, so as to control the amount or time of each drop of powder coating.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figures 1 to 3This utility model provides an embodiment of an automatic weighing device for powder coatings, comprising a weighing body 1, supporting components, and a weighing platform 36 for weighing bags containing powder coatings. The weighing data from the platform 36 is transmitted to a control terminal 41. A sliding plate 2 is fixedly connected to the top of the weighing body 1 to connect and support the supporting components, and also has a sliding groove to guide the sliding direction of an automatic gripper 5. A telescopic component is fixedly connected to the top of the weighing body 1 to provide power to drive the automatic gripper 5 to slide. The automatic gripper 5 is fixedly connected to the outside of the telescopic component. The automatic gripper 5 has two telescopic rods sleeved on it, with a clamping block sleeved at one end of each rod. The automatic gripper 5 is controlled by the control terminal 41 via electronic signals to provide power, causing the internal telescopic rods to extend and retract, thereby sliding the bag to below the discharge cylinder. A second cylinder 6 is slidably connected to the outside of the automatic gripper 5. The second cylinder 6 is controlled by the control terminal via electronic signals to raise and lower a lifting rod, thereby moving the bag... The bag opener 7 rises and falls, allowing the insert rod of the bag opener 7 to be inserted into the bag. A lifting rod is fitted onto the drive end of cylinder 2 6. The bag opener 7 is slidably connected to the outside of the automatic gripper 5. The bag opener 7 is controlled by a control terminal via electronic signals, providing power to extend and retract the telescopic rod, thereby moving the insert rod already inserted into the bag outwards to open the bag. Opposing telescopic rods are fitted inside the bag opener 7, with the insert rod fitted onto one end of each telescopic rod. A hinge 8 is fixedly connected to one end of the sliding plate 2. A stop block 10 is fixedly connected to one end of the slide plate 2. When the rotating plate 9 rotates to a certain angle, it is blocked by the stop block 10 to prevent the rotating plate 9 from continuing to rotate. The bottom of one end of the hinge 8 is fixedly connected to the rotating plate 9. The rotating plate 9 is rotatably connected to the slide plate 2 through the hinge 8. By rotating, it is convenient to insert the bag into the insertion rod 11. When a certain number of bags are loaded, the rotating plate 9 is rotated so that the bag opener 7 can clamp the bag. The insertion rod 11 is fixedly connected to the outside of the rotating plate 9. The two ends of the bag are inserted into the insertion rod 11.

[0044] Reference Figures 2 to 4A fixed plate 12 is fixedly connected to one end of the rotating plate 9, which fixes the cylindrical connecting blocks 13 arranged in a row. Multiple rotating components that allow the partitions 15 to rotate are fixedly connected to the bottom of the fixed plate 12. In order for the multiple partitions 15 to rotate and separate the bags at the same time, the telescopic component includes a cylinder 3. The drive end of the cylinder 3 is fixedly connected to a telescopic rod 4. The cylinder 3 provides power to drive the telescopic rod 4 to extend and retract, thereby allowing the telescopic rod 4 to drive the automatic gripper 5 to slide. The rotating component includes a cylindrical connecting block 13. A rotating shaft 14 is rotatably connected to the inner wall of the cylindrical connecting block 13. The partitions 15 are fixedly connected to the outside of the rotating shaft 14. The cylindrical connecting block 13 is fixed to the bottom of the fixed plate 12 and rotates to connect with the rotating shaft 14, forming a hinge-like effect, allowing the partitions 15 to rotate. While the partitions 15 separate the bags, the bag expander 7 clamps the bags and slides. The partitions 15 protect and prevent the bags from moving.

[0045] Reference Figure 5 , Figure 6 A cylinder 16 is fixedly connected to the top of the weighing device body 1. A telescopic rod 17 is fixedly connected to the drive end of the cylinder 16. A fixed circular belt 18 is fixedly connected to the outside of the telescopic rod 17. The cylinder 16 provides power to extend and retract the telescopic rod 17, thereby adjusting the height of the telescopic rod 17 along with the fixed circular belt 18. This allows the height of the frustum-shaped loading cylinder 19 fixed to the fixed circular belt 18 to be adjusted. The frustum-shaped loading cylinder 19, used to hold powder coating, is slidably connected to the inner wall of the fixed circular belt 18. A feed pipe 20 is fixedly connected to the top of the frustum-shaped loading cylinder 19 to feed the powder coating into the frustum-shaped loading cylinder 19. 9. A motor 21 is fixedly connected to the top of the frustum-shaped loading cylinder 19 to provide power to drive the rotating shaft 22 to rotate. A discharge cylinder 25 is fixedly connected to the bottom of the frustum-shaped loading cylinder 19 to allow the powder coating inside the frustum-shaped loading cylinder 19 to exit. The drive end of the motor 21 is fixedly connected to the rotating shaft 22. Multiple connecting rods 23 are fixedly connected to the outside of the rotating shaft 22. Stirring blades 24 are fixedly connected to the outside of the multiple connecting rods 23. The rotating shaft 22 is used to drive the stirring blades 24 connected to the connecting rods 23 to rotate. The stirring blades 24 can prevent the powder coating from clogging the discharge cylinder 25.

[0046] Reference Figures 5 to 7A motor 26 is fixedly connected to the outside of the discharge cylinder 25. A rotating shaft 27 is fixedly connected to the drive end of the motor 26. A closing plate 28 is fixedly connected to the outside of the rotating shaft 27. The motor 26 provides power to drive the rotating shaft 27 to rotate, thereby driving the closing plate 28 to rotate. The closing plate 28 can block the discharge cylinder 25. The amount of powder coating falling off the closing plate 28 is controlled by its rotation. A U-shaped placement rod 30 is fixedly connected to the outside of the discharge cylinder 25 to fix the discharge cylinder 25 and to rotatably connect the rotating rod 31. A fixing plate 2 is fixedly connected to one end of the U-shaped placement rod 30. 9. A rotating rod 31 is rotatably connected to the outside of the U-shaped placement rod 30. A connecting rod 2 34 is fixedly connected to one side of the rotating rod 31. A cylinder 32 is fixedly connected to the outside of the rotating rod 31. A telescopic rod 33 is fixedly connected to the drive end of the cylinder 32. A clamping plate 35 is fixedly connected to the bottom of the rotating rod 31. Two opposing cylinders 32 provide power to drive the telescopic rod 33 to extend and retract, thereby driving the two rotating rods 31 connected by the connecting rod 2 34 to rotate in opposite directions. This allows the two clamping plates 35 connected to the rotating rod 31 to clamp the opened bag onto the discharge cylinder 25, allowing the powder coating to fall into the bag.

[0047] Reference Figure 1 , Figure 8 A weighing platform 36 is fixedly connected to the bottom side of the weighing device body 1, which is used to place the items to be weighed. A fixed plate 37 is fixedly connected to the top of the weighing platform 36, which is rotatably connected to the rotating shaft 39 to keep the rotating shaft 39 horizontal. A power unit 38 is fixedly connected to the outside of the fixed plate 37. The drive end of the power unit 38 is fixedly connected to the rotating shaft 39. A roller 40 is fixedly connected to the outside of the rotating shaft 39. The power unit 38 provides power to control the rotation of the rotating shaft 39, thereby causing the rotating shaft 39 to drive the roller 40 to rotate, so that the weighed bag containing powder coating is removed. A control terminal 41 is fixedly connected to the outside of the weighing device body 1, which is used to display the weighing results in real time. The control terminal 41 controls the automatic clamp 5, the cylinder 6 and the bag opener 7 through electronic signals.

[0048] Working principle: First, the rotating plate 9 is rotatably connected to the sliding plate 2 via the hinge 8. Rotating the rotating plate 9 allows the bags to be placed on the insertion rod 11 and separated by the partition 15. After a certain number of bags are loaded, rotating the rotating plate 9 is rotated back. This activates the cylinder 3 at the top of the weighing unit 1, causing the telescopic rod 4 to extend and retract. When the telescopic rod 4, carrying the automatic clamp 5, slides to the left or right of the bags inserted on the insertion rod 11, the control terminal 41 provides electrical power to the telescopic rod inside the automatic clamp 5 via electronic signals, allowing the telescopic rod to move with the two clamping blocks. The bag is clamped by the elastic rod 4, which extends and retracts to move the clamped bag to the bottom of the discharge cylinder 25. At this time, the control terminal 41 controls the cylinder 6 via electronic signal to lower the lifting rod of the cylinder 6, allowing the insert rod connected to the internal telescopic rod of the bag opener 7 to be inserted into the bag. At the same time, the control terminal 41 controls the bag opener 7 via electronic signal to provide power, which drives the opposing telescopic rods inside the bag opener 7 to extend and retract, causing the insert rod to move to both sides inside the bag, thereby opening the bag opening and achieving the effect of opening the bag.

[0049] Subsequently, the two opposing cylinders 32 are activated to extend and retract the telescopic rods 33, causing the two opposing telescopic rods 33 to move outward along with the rotating rod 31. Since one end of the rotating rod 31 is rotatably connected to the U-shaped placement rod 30, the rotating rod 31 rotates outward, thereby opening the clamping plate 35 and allowing the clamping plate 35 to rotate as well. The two clamping plates 35 then rotate inward to clamp the bag onto the discharge cylinder 25, allowing the powder coating to fall smoothly into the bag. The bag is then weighed through the weighing platform 36 connected to the weighing device body 1, and the weighing process is observed in real time through the control terminal 41.

[0050] At the same time, the feed pipe 20 transports the powder coating into the frustum loading cylinder 19. The motor 21 is started to drive the connecting rod 23 connected to the rotating shaft 22 to rotate, thereby driving the stirring blade 24 to stir the powder coating and prevent the powder coating from blocking the discharge cylinder 25. At the same time, the motor 26 is started to drive the rotating shaft 27 to rotate, thereby driving the closing plate 28 to rotate and controlling the powder coating to fall from the discharge cylinder 25.

[0051] Finally, the starter motor 38 drives the rotating shaft 39 to rotate, which in turn causes the rotating shaft 39 to rotate the roller 40, thus removing the bag containing the powder coating.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
