Description

Technical Field

[0001] The present application relates to the technical field of paint production, and in particular to an automatic production device for safe and environmentally friendly paint. Background Art

[0002] In paint production, powdery raw materials need to be added to a mixing tank, and then some additives are mixed. After being evenly stirred in the mixing tank, a part of the paint needs to be made into cakes and ground into powder, and another part of the paint is directly filled.

[0003] In the related art, an opening is provided at the upper part of the mixing tank used in paint production, and a cover body is installed at the position of the opening. During the stirring process in the mixing tank, the cover body covers the opening to reduce the powder in the mixing tank from floating out of the opening and reduce environmental pollution. In order to pour materials into the mixing tank, during the setting of the mixing tank, the mixing tank is embedded in the bottom plate of the second layer, so that a part of the mixing tank is located above the bottom plate and another part is located below the bottom plate, so that it is easier for workers to reach the opening position at the upper part of the mixing tank for feeding.

[0004] However, when the above-mentioned structure is used and workers directly add powdery raw materials from the opening position, the powdery raw materials are usually packed in woven bags or plastic bags, and the package is kept outside the opening. The powdery raw materials flow downward from the opening position, and the powdery raw materials are affected by the air in the mixing tank to form floating powder and fly out from the opening, thereby affecting the working environment around the mixing tank. Summary of the Invention

[0005] In order to reduce the powdery raw materials from floating out of the mixing tank when adding powdery raw materials into the mixing tank, the present application provides an automatic production device for safe and environmentally friendly paint.

[0006] The present application provides an automatic production device for safe and environmentally friendly paint, adopting the following technical solutions:

[0007] An automatic production device for safe and environmentally friendly paint, including a mixing tank, an opening is provided at the top of the mixing tank; a cover body for covering the opening is provided at the position where the mixing tank is provided with the opening, and a rotating frame is rotatably arranged inside the mixing tank; the rotating frame is connected with a driving component; one end of the rotating frame far away from the mixing tank is moved out of the mixing tank from the opening through the driving component; an extending component is arranged at one end of the rotating frame far away from the mixing tank; one end of the extending component is installed on the rotating frame, and the other end is provided with a bag clamping component; the bag clamping component and the extending component enter the mixing tank from the opening along with the rotating frame; a bag removing component is arranged in the mixing tank.

[0008] By adopting the above technical solution, during use, place the package containing the powder raw material on one side of the opening of the mixing tank, then open the cover of the mixing tank, and through the driving assembly, drive the rotating frame with the extending assembly to move the extending assembly out of the mixing tank. Then, the bag clamping assembly on the extending assembly reaches the position of the package, and the bag clamping assembly clamps the upper part of the package. Then, the rotating frame drives the bag clamping assembly, the extending assembly and the package to enter the mixing tank simultaneously, close the cover, and open the package through the bag opening assembly located inside the mixing tank. Since the package is opened inside the mixing tank and the opening is covered by the cover, it is possible to reduce the powder raw material floating out of the mixing tank from the opening position when adding the powder raw material into the mixing tank.

[0009] Preferably, the extending assembly includes two telescopic hydraulic cylinders; a driving hydraulic cylinder is arranged between the extending assembly and the rotating frame; one end of the extending assembly is rotatably connected to the rotating frame; one end of the driving hydraulic cylinder is rotatably connected to the extending assembly, and the other end is rotatably connected to the rotating frame.

[0010] By adopting the above technical solution, the driving hydraulic cylinder is arranged between the extending assembly and the rotating frame, enabling the driving hydraulic cylinder to drive the extending assembly to rotate relative to the rotating frame.

[0014] By adopting the above technical solution, the clamping rod is cylindrical. When the clamping rod is fixed by the locking motor, the locking motor prevents one clamping rod from rotating and cooperates with the other clamping rod to clamp the package. When the locking motor rotates, the two clamping rods rotate simultaneously, which can drive the package to wrap around the clamping rod along the guiding channel, thereby achieving winding the package and reducing the powder raw material floating off after the package is removed from the mixing tank.

[0015] Preferably, the guiding channel is formed by arranging an upper guiding plate above the clamping rod and a lower guiding plate below the clamping rod; the upper guiding plate extends gradually upward and toward the clamping rod detachably connected to the hanging bracket; the lower guiding plate covers the lower part of the lower guiding plate.

[0016] By adopting the above technical solution, the upper guiding plate and the lower guiding plate cooperate to form a guiding channel, so that the upper guiding plate and the lower guiding plate guide the packaging, facilitating the clamping rod to be removed from between the upper guiding plate and the lower guiding plate, and then removing the packaging wound on the clamping rod.

[0017] Preferably, the driving assembly includes a worm gear, a worm and a driving motor; the worm gear is coaxially fixed on the rotating frame; the driving motor is fixed on the mixing tank; the worm is coaxially connected to the output shaft of the driving motor; the worm gear meshes with the worm.

[0018] By adopting the above technical solution, when the driving motor rotates, the driving motor drives the worm to rotate, and the worm then drives the worm gear to rotate, causing the rotating frame to rotate under the action of the worm gear, so that the rotating frame can rotate stably, and at the same time, the rotation angle of the rotating frame can be larger.

[0019] Preferably, the bag-opening assembly includes a telescopic rod and a heating wire; one end of the telescopic rod is connected to the inner wall of the mixing tank, and the other end is used for installing the heating wire.

[0020] By adopting the above technical solution, the heating wire is installed on the telescopic rod, and the heating wire can be driven by the telescopic rod to approach the packaging, and then the heating wire melts the packaging, so that it can be more convenient to open.

[0021] Preferably, the end of the telescopic rod away from the heating wire is rotatably connected to the mixing tank, and an adjusting hydraulic cylinder is arranged between the telescopic rod and the mixing tank; one end of the adjusting hydraulic cylinder is rotatably connected to the telescopic rod, and the other end is rotatably connected to the mixing tank.

[0022] By adopting the above technical solution, the adjusting hydraulic cylinder is arranged between the telescopic rod and the mixing tank, and the adjusting hydraulic cylinder can drive the telescopic rod to rotate, so as to adjust the height of the heating wire installed on the telescopic rod, and thus adapt to different packages.

[0023] Preferably, the opening is located at one side of the top of the mixing tank, and an air extraction pipe is arranged on the side of the top of the mixing tank far away from the opening; a suction fan is connected to the air extraction pipe; the air extraction pipe is communicated with the inside of the mixing tank.

[0024] By adopting the above technical solution, an air extraction pipe is arranged on one side of the top of the mixing tank far away from the opening. After pouring the powdered raw material, the air extraction fan can reduce the outward floating of the powdered raw material from the opening position after the opening is opened.

[0025] Preferably, a filter screen is arranged at the connection between the air extraction pipe and the mixing tank.

[0026] By adopting the above technical solution, a filter screen is arranged at the connection between the air extraction pipe and the mixing tank, so that the filter screen can filter the air flow passing through the air extraction pipe, and at the same time, the powdered raw material on the filter screen can also fall back into the mixing tank.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The driving component drives the rotating frame with the extending component, so that the extending component moves out of the mixing tank. Then, the bag clamping component on the extending component reaches the packaging position. Further, the bag clamping component clamps the upper part of the packaging, and then the rotating frame drives the bag clamping component, the extending component and the packaging to enter the mixing tank at the same time and close the cover. The packaging is opened by the bag opening component located inside the mixing tank. Since the packaging is opened inside the mixing tank and the opening is covered by the cover, it is possible to reduce the floating of the powdered raw material from the opening position out of the mixing tank when adding the powdered raw material into the mixing tank;

[0029] 2. By arranging the driving hydraulic cylinder between the extending component and the rotating frame, the driving hydraulic cylinder can drive the extending component to rotate relative to the rotating frame. On the one hand, the driving hydraulic cylinder can adjust the height of the bag clamping component on the extending component. On the other hand, when passing through the opening of the mixing tank, the extending component rotates towards the rotating frame to adapt to a smaller opening;

[0030] 3. The locking motor prevents one clamping rod from rotating and cooperates with the other clamping rod to clamp the packaging; when the locking motor rotates, the two clamping rods rotate simultaneously to drive the packaging to be wrapped around the clamping rod along the guiding channel, thereby achieving winding the packaging and reducing the powdered raw material floating and falling after the packaging is moved out of the mixing tank.

Detailed implementation manners

[0037] The following further elaborates on the present application in conjunction with the Figures 1 - 5 drawings for a more detailed description.

[0038] The embodiment of the present application discloses an automatic production device for safe and environmentally friendly coatings. Referring to Figure 1 , it includes a mixing tank 1. An opening 11 is provided at the top of the mixing tank 1, and a cover 12 is provided on the mixing tank 1. The cover 12 is rotatably connected to the position of the opening 11 of the mixing tank 1, and the cover 12 is used to cover the opening 11 of the mixing tank 1. When raw materials need to be added into the mixing tank 1, the cover 12 is opened. An extending assembly 2 is provided inside the mixing tank 1 and at the position of the opening 11. One end of the extending assembly 2 is close to the opening 11, and the other end extends to the outside of the mixing tank 1 and is equipped with a bag-clamping assembly 3. The bag-clamping assembly 3 is used to clamp the packaging 01 of the powder raw materials, and then it is retracted into the mixing tank 1 through the extending assembly 2.

[0039] Referring to Figure 2, a rotating frame 4 is fixedly arranged on the inner wall of the stirring tank 1. The rotating frame 4 is L-shaped. One end of the rotating frame 4 is rotatably connected to the top inner wall of the stirring tank 1. A rotating shaft 41 is rotatably connected to the stirring tank 1. The rotating frame 4 is rotatably connected to the stirring tank 1 through the rotating shaft 41, and the rotating shaft 41 is fixedly connected to the rotating frame 4. The other end of the rotating frame 4 rotates upward under the action of the rotating shaft 41 and extends out of the stirring tank 1 from the position of the opening 11. When the rotating frame 4 rotates downward, the end of the rotating frame 4 away from the rotating shaft 41 rotates downward into the interior of the stirring tank 1. The extending assembly 2 is installed at the end of the rotating frame 4 away from the rotating shaft 41. The extending assembly 2 enters and exits the stirring tank 1 from the position of the opening 11 through the rotating frame 4. After the extending assembly 2 cooperates with the bag clamping assembly 3 to clamp the package 01 of the powder raw material and enters the stirring tank 1, then after the cover body 12 covers the opening 11, the package 01 of the powder raw material is opened, so as to prevent the floating powder from flying out of the stirring tank 1 from the position of the opening 11.

[0040] Reference Figure 2 , a driving assembly 5 is installed on the rotating shaft 41. The driving assembly 5 includes a worm gear 51, a worm 52 and a driving motor 53. The worm gear 51 is coaxially fixed on the rotating shaft 41. The driving motor 53 is fixed on the stirring tank 1. The output shaft of the driving motor 53 is coaxially fixedly connected to the worm 52. The worm gear 51 meshes with the worm 52. By driving the worm 52 to rotate through the driving motor 53, the worm gear 51 drives the rotating shaft 41, so that the end of the rotating frame 4 away from the rotating shaft 41 can enter and exit the stirring tank 1 from the position of the opening 11. And through the worm gear 51 and the worm 52, the rotating frame 4 can be driven relatively stably, and at the same time, the rotation range of the rotating frame 4 is relatively large, so that the rotating frame 4 can extend out of the opening 11 more conveniently.

[0041] Reference Figure 2, a driving hydraulic cylinder 6 is arranged between the extending component 2 and the rotating frame 4. The extending component 2 includes two telescopic hydraulic cylinders 21. One end of the telescopic hydraulic cylinder 21 is rotatably connected to the rotating frame 4, and the other end is the output end for installing the bag clamping component 3. One end of the driving hydraulic cylinder 6 is rotatably connected to the extending component 2, and the other end is rotatably connected to the rotating frame 4. The rotating connection between the extending component 2 and the rotating frame 4 is driven by the driving hydraulic cylinder 6 to adjust the angle between the extending component 2 and the rotating frame 4. After moving the extending component 2 to the outside of the mixing tank 1 through the rotating frame 4, the driving hydraulic cylinder 6 drives the extending component 2 to adjust up and down, so as to adjust the height of the bag clamping component 3 located on the extending component 2. The bottom plate arranged outside the mixing tank 1 can be used to place the package 01 of the powder raw material, and then move to the package 01 placed on the bottom plate during the height adjustment process of the bag clamping component 3, and clamp the upper edge of the package 01 through the bag clamping component 3. When the driving component 5 drives the rotating frame 4 to rotate towards the inside of the mixing tank 1, the angle between the extending component 2 and the rotating frame 4 is reduced by the driving hydraulic cylinder 6, so that the position of the extending component 2 needs to be adjusted, which is convenient for the end of the extending component 2 far from the rotating frame 4 to enter the mixing tank 1 and is convenient for adapting to the opening 11 with a smaller size.

[0042] Reference Figure 3 and Figure 4 , the bag clamping component 3 includes a hanging frame 31, a suspension shaft 32 and two horizontal clamping rods 33. The two clamping rods 33 are arranged in parallel and at intervals. A power component 34 for driving one clamping rod 33 to approach the other clamping rod 33 is installed on the hanging frame 31. The suspension shaft 32 is fixed at the end of the extending component 2 far from the rotating frame 4. The upper part of the hanging frame 31 is rotatably connected to the suspension shaft 32. The suspension shaft 32 is located above the position between the two clamping rods 33. The package 01 of the powder raw material is clamped between the two clamping rods 33, and under the action of the gravity of the bag clamping component 3 and the package 01, the package 01 is kept in a vertical position.

[0043] Reference Figure 3 and Figure 4, a sliding seat 35 is installed at the end of the clamping rod 33. Slide bars 311 are provided on the opposite surfaces of the two hanging brackets 31. The sliding seat 35 is slidably engaged with the slide bars 311. A pin 351 is provided on the sliding seat 35 of one of the clamping rods 33. The pin 351 penetrates through the sliding seat 35 and the slide bar 311, and the clamping rod 33 is installed on the slide bar 311; when it needs to be removed, first remove the pin 351, and then the clamping rod 33 can be moved along the length direction of the slide bar 311; a locking motor 36 is provided at the end of the other clamping rod 33, and the locking motor 36 is a reduction motor that can prevent the clamping rod 33 from driving the motor to rotate. Only the locking motor 36 can drive the clamping rod 33 to rotate. Both clamping rods 33 are cylindrical. When the two clamping rods 33 clamp the package 01 of the powder raw material, the locking motor 36 can prevent the clamping rod 33 from rotating. A chute 312 is provided on the hanging bracket 31. The chute 312 is arranged parallel to the slide bar 311. An installation block 361 is slidably arranged in the chute 312. The installation block 361 is connected to the clamping rod 33 connected to the locking motor 36. The installation block 361 is used to fix the locking motor 36. The output shaft of the locking motor 36 is coaxially fixed to the clamping rod 33. The power member 34 is an electric cylinder. The power member 34 is fixed on the hanging bracket 31. The power member 34 is arranged parallel to the chute 312, and the output end of the power member 34 is fixed on the installation block 361. When the installation block 361 is driven by the power member 34 to move along the chute 312, the two clamping rods 33 can be moved closer to or away from each other.

[0044] Reference Figure 3 , an upper guide plate 37 and a lower guide plate 38 are fixedly arranged on the hanging bracket 31. The upper guide plate 37 is located above the position between the two clamping rods 33, and the lower surface of the upper guide plate 37 is arc-shaped. The upper guide plate 37 gradually approaches the direction of the clamping rod 33 that can be disassembled by the pin 351 from bottom to top. The lower guide plate 38 is located below the detachable clamping rod 33 and covers the lower part of the clamping rod 33. The upper surface of the lower guide plate 38 is arranged in an arc shape, so that a guiding channel 39 is formed between the upper guide plate 37, the lower guide plate 38 and the outer wall of the clamping rod 33. The guiding channel 39 at the position of the upper guide plate 37 is used to offset the package 01 of the powder raw material towards the detachable clamping rod 33, and then enter the position of the lower guide plate 38 during the downward movement of the package 01, and wind around the side wall of the detachable clamping rod 33 along the guiding channel 39. After the package 01 of the powder raw material is opened and the raw material is poured into the mixing tank 1, the locking motor 36 drives the clamping rod 33 to rotate. When the two clamping rods 33 clamp and convey the package 01, the package 01 is wrapped around one clamping rod 33 along the guiding channel 39. Then when the bag clamping assembly 3 extends out of the mixing tank 1, the detachable clamping rod 33 is removed, and the wound package 01 is removed along the axial direction, which can further reduce the powder dropping in the package 01.

[0045] Reference Figure 5, a bag-unpacking assembly 7 is arranged inside the stirring tank 1. The bag-unpacking assembly 7 includes a telescopic rod 71 and a heating wire 72. One end of the telescopic rod 71 is rotatably connected to the inner part of the stirring tank 1, and the other end is used for installing the heating wire 72. The heating wire 72 is arranged parallel to the bag-clamping assembly 3. When the heating wire 72 moves towards the package 01 through the telescopic rod 71, the heating wire 72 can melt and unpack the package 01, so that the powder inside the package 01 flows out into the stirring tank 1. The telescopic rod 71 is a hydraulic cylinder. An adjusting hydraulic cylinder 73 is arranged between the telescopic rod 71 and the inner wall of the stirring tank 1. One end of the adjusting hydraulic cylinder 73 is rotatably connected to the stirring tank 1, and the other end is rotatably connected to the telescopic rod 71. By the telescopic movement of the adjusting hydraulic cylinder 73, the end of the telescopic rod 71 where the heating wire 72 is installed can move up and down. Cooperating with the telescopic movement of the telescopic rod 71, the height of the heating wire 72 can be adjusted, so as to unpack different packages 01. The opening 11 of the stirring tank 1 is located at the top edge of the stirring tank 1. The bag-unpacking assembly 7 is arranged on one side of the opening 11 close to the middle of the stirring tank 1, so that after the extending assembly 2 moves into the stirring tank 1, it moves towards the middle of the top of the stirring tank 1, and the generated powder can also be more easily blocked by the top of the stirring tank 1, reducing the floating out of the stirring tank 1.

[0046] Reference Figure 1 , an air extraction pipe 81 is arranged on one side of the top of the stirring tank 1 far away from the opening 11. The air extraction pipe 81 is connected to the inside of the stirring tank 1, and a filter screen is installed at the connection between the air extraction pipe 81 and the stirring tank 1. One end of the air extraction pipe 81 far away from the stirring tank 1 is provided with an air extraction fan 82. The air extraction fan 82 extracts air from the stirring tank 1 through the air extraction pipe 81, reducing the outflow of the gas in the stirring tank 1 from the position of the opening 11 when the cover body 12 is opened.

[0047] The working process of this embodiment:

[0048] The staff first place the package 01 on the bottom plate, then move the extending assembly 2 outside the stirring tank 1 through the rotating frame 4 and approach the package 01. Then, the bag-clamping assembly 3 on the extending assembly 2 clamps the upper part of the package 01, and then the rotating frame 4 brings the package 01 into the stirring tank 1 from the position of the opening 11 and closes the cover body 12; then the bag-unpacking assembly 7 inside the stirring tank 1 opens the package 01, so that the powder raw material flows into the stirring tank 1, and then the clamping rod 33 rotates to wind the package 01 around the detachable clamping rod 33. When the extending assembly 2 extends out of the stirring tank 1 again, the package 01 on the clamping rod 33 is taken off.

[0049] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this.
