Description

Technical Field

[0001] This utility model relates to the field of paint production technology, specifically to an equal-volume filling device for paint production. Background Technology

[0002] Paint is one of the most widely used decorative and protective materials on the market. With continuous social development, the demand for paint is gradually increasing, leading to a growing need for paint production equipment. In the paint production process, the final step is filling the paint, making paint filling equipment particularly important.

[0003] A paint filling device for production, disclosed in publication number CN 214218130 U, includes a support frame. The support frame suspends and fixes the filling machine in the air via stabilizing rods connected at both ends. A nozzle is connected to the center of the bottom of the filling machine, and a conveyor belt is installed directly below the nozzle. A rectangular support plate is installed in the middle of the support frame, and a fixed base is installed on one side of the support plate. An electric telescopic rod is installed on the other side of the fixed base, which moves a sponge pad outward along the bottom of the nozzle to wipe away residual paint on the nozzle. This effectively prevents residual paint from dripping onto the filling machine or the cans to be filled in the next round. After one round of cleaning, the electric telescopic rod pulls the base plate backward, causing the sliding rods on both sides to squeeze the sponge pad and dehydrate it. The sponge pad can be dehydrated after each round of cleaning to prevent it from becoming saturated too early, thus increasing its service life and allowing for cyclical cleaning of the nozzle.

[0004] However, the above-mentioned filling device still has some shortcomings in use. The flow rate of the paint cannot be precisely controlled during filling, resulting in uneven filling and affecting the filling quality. At the same time, the paint is stored inside the box before filling, which easily causes sedimentation, making the paint stick to the inner wall of the box and difficult to handle, thus affecting the feeding. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an equal-volume filling device for paint production, which solves the problem that the paint flow rate cannot be precisely controlled during filling, resulting in uneven paint filling and affecting the filling quality. In addition, if the paint is stored inside the box before filling, it is easy for sediment to form, causing the paint to stick to the inner wall of the box, making it difficult to handle and affecting the feeding.

[0006] This utility model provides the following technical solution: an equal-volume filling device for paint production, comprising a base plate, four support rods fixedly connected to the upper surface of the base plate, a paint tank fixedly connected between the four support rods, a discharge pipe connected to the bottom end of the paint tank, a placement plate fixedly connected to the upper surface of the base plate, a placement groove formed on the upper surface of the placement plate, a filling barrel disposed inside the placement groove, a disc fixedly fitted onto the surface of the discharge pipe, two sets of fixing plates fixedly connected to the upper surface of the disc, a bidirectional lead screw rotatably connected between one set of fixing plates, two lead screw sleeves threaded onto the surface of the bidirectional lead screw, the bottom ends of the two lead screw sleeves extending to the bottom of the disc and fixedly connected to baffle plates, a first motor fixedly connected to the side of one of the fixing plates, the output end of the first motor penetrating the fixed plate and fixedly connected to one end of the bidirectional lead screw.

[0007] Preferred technical solution 1: A limiting rod is fixedly connected between another set of fixed plates. Two limiting sleeves are slidably sleeved on the surface of the limiting rod. The bottom ends of the two limiting sleeves extend to the bottom of the disc and are fixedly connected to the two baffles respectively. Two slots are opened on the upper surface of the disc. The two lead screw sleeves and the two limiting sleeves can move inside the two slots respectively.

[0008] This solution can restrict the movement of the baffle plate by using a limiting sleeve, making it easier to control the falling of the coating.

[0009] Preferred technical solution 2: Four weighing sensors are fixedly installed on the inner bottom wall of the placement trough, and a support plate is installed on the top of the four weighing sensors. The filling barrel is placed on the support plate.

[0010] This solution enables the monitoring and control of the weight of the filling barrel and the internal coating.

[0011] Preferred technical solution 3: A second motor is fixedly connected to the top of the paint tank, the output end of the second motor extends into the interior of the paint tank and is fixedly connected to a stirring rod, and two rows of stirring rods are fixedly connected to the surface of the stirring rod.

[0012] This solution uses a second motor to drive a stirring rod to continuously stir the coating, preventing it from solidifying.

[0013] Preferred technical solution four: a scraper is fixedly connected to one end of each of the two rows of stirring rods, and both scrapers are in contact with the inner wall of the paint tank.

[0014] This solution can remove paint adhering to the inner wall of the paint can using a scraper, reducing waste.

[0015] Preferred technical solution five: The bottom end of the stirring rod extends into the interior of the discharge pipe and is fixedly connected to an auger, the auger being close to the inner wall of the discharge pipe.

[0016] This solution uses the rotation of the auger to ensure the paint falls evenly, preventing blockages.

[0017] Compared with the prior art, this utility model provides an equal-volume filling device for paint production, which has the following beneficial effects: In use, the filling barrel is placed on the support plate inside the placement plate, and the filling barrel is weighed by a weighing sensor. Then, the forward rotation of the first motor drives the bidirectional lead screw to rotate in the forward direction, causing the two lead screw sleeves and two baffle plates to move in opposite directions, exposing the discharge port of the discharge pipe. Then, the forward rotation of the second motor drives the stirring rod and the auger to rotate, and the auger evenly transports the paint inside the paint tank to the outside, falling into the inside of the filling barrel. When the weighing sensor senses that the filling barrel and the paint inside have reached the preset weight, the first motor is controlled to rotate in the reverse direction, driving the two baffle plates to block and seal the bottom of the discharge pipe, preventing the paint from falling further. At the same time, the second motor is controlled to rotate in the reverse direction, driving the auger to rotate in the reverse direction, conveying the paint upward. Meanwhile, the stirring rod continuously stirs the paint to prevent solidification. Then, the filled filling barrel can be taken out and put into a new filling barrel for subsequent filling operations, which is convenient and fast. Attached Figure Description

[0024] Example 1: A paint production equal-volume filling device includes a base plate 1, four support rods 2 are fixedly connected to the upper surface of the base plate 1, paint tanks 3 are fixedly connected between the four support rods 2, a discharge pipe 4 is connected to the bottom end of the paint tank 3, a placement plate 5 is fixedly connected to the upper surface of the base plate 1, a placement groove 6 is opened on the upper surface of the placement plate 5, a filling barrel 7 is arranged inside the placement groove 6, a disc 8 is fixedly sleeved on the surface of the discharge pipe 4, two sets of fixing plates 9 are fixedly connected to the upper surface of the disc 8, a bidirectional lead screw 10 is rotatably connected between one set of fixing plates 9, two lead screw sleeves 11 are threaded on the surface of the bidirectional lead screw 10, the bottom ends of the two lead screw sleeves 11 extend to the bottom of the disc 8 and are fixedly connected to baffle plates 12, a first motor 13 is fixedly connected to the side of one of the fixing plates 9, the output end of the first motor 13 passes through the connected fixing plate 9 and is fixedly connected to one end of the bidirectional lead screw 10.

[0025] Example 2: The difference between this example and Example 1 is that a limiting rod 14 is fixedly connected between another set of fixed plates 9. Two limiting sleeves 15 are slidably sleeved on the surface of the limiting rod 14. The bottom ends of the two limiting sleeves 15 extend to the bottom of the disc 8 and are fixedly connected to the two baffle plates 12 respectively. Two slots are opened on the upper surface of the disc 8. The two screw sleeves 11 and the two limiting sleeves 15 can move inside the two slots respectively. The movement of the baffle plates 12 is restricted by the limiting sleeves 15, which facilitates the control of the paint falling.

[0026] Example 3: The difference between this example and Example 1 is that four weighing sensors 16 are fixedly installed on the bottom wall of the placement trough 6, and a support plate 17 is installed on the top of the four weighing sensors 16. The filling barrel 7 is placed on the support plate 17, which facilitates the monitoring and control of the weight of the filling barrel 7 and the coating inside.

[0027] Example 4: The difference between this example and Example 1 is that a second motor 18 is fixedly connected to the top of the paint tank 3. The output end of the second motor 18 extends into the interior of the paint tank 3 and is fixedly connected to a stirring rod 19. Two rows of stirring rods 20 are fixedly connected to the surface of the stirring rod 19. The second motor 18 drives the stirring rods 20 to continuously stir the paint and prevent the paint from solidifying.

[0028] Example 5: The difference between this example and Example 1 is that each of the two rows of stirring rods 20 is fixedly connected to a scraper 21 at one end. Both scrapers 21 are in contact with the inner wall of the paint tank 3. The paint adhering to the inner wall of the paint tank 3 is scraped off by the scrapers 21 to reduce waste.

[0029] Example 6: The difference between this example and Example 1 is that the bottom end of the stirring rod 19 extends into the inside of the discharge pipe 4 and is fixedly connected to an auger 22. The auger 22 is close to the inner wall of the discharge pipe 4. The rotation of the auger 22 can make the coating fall evenly and avoid clogging.

[0030] In summary, this equal-volume filling device for paint production operates by placing the filling barrel 7 on the support plate 17 inside the placement plate 5. The filling barrel 7 is weighed using the weighing sensor 16. Then, the forward rotation of the first motor 13 drives the bidirectional lead screw 10 to rotate forward, causing the two lead screw sleeves 11 and the two baffle plates 12 to move in opposite directions, exposing the discharge port of the discharge pipe 4. Next, the forward rotation of the second motor 18 drives the stirring rod 19 and the auger 22 to rotate, and the auger 22 evenly transports the paint inside the paint tank 3 to the outside. The paint falls into the filling barrel 7. When the weighing sensor 16 senses that the filling barrel 7 and the paint inside have reached the preset weight, it controls the first motor 13 to rotate in the opposite direction, driving the two baffles 12 to block and seal the bottom of the discharge pipe 4, preventing the paint from falling further. At the same time, it controls the second motor 18 to rotate in the opposite direction, driving the auger 22 to rotate in the opposite direction, conveying the paint upward. Meanwhile, the stirring rod 20 continuously stirs the paint to prevent it from solidifying. Then, the filled filling barrel 7 can be taken out and put into a new filling barrel 7 for subsequent filling operations, which is convenient and quick.
