Description

Technical Field

[0001] The invention relates to the field of cleaning, in particular to a device for cleaning a water-based ink storage tank. Background Art

[0002] During the storage of water-based ink, the water-based ink may precipitate or evaporate due to long storage time, leaving residues in the storage tank. To prevent these residues from affecting the quality of the subsequent stored ink, when replacing the stored ink, the storage tank must be thoroughly cleaned to remove these residues.

DETAILED DESCRIPTION

[0026] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects of the present invention, the following is a detailed description in combination with the specific embodiments listed and the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention.

[0027] Embodiment: A cleaning device for a water-based ink storage tank, see Figure 1-Figure 3 , including: a bottom plate 1; a table 2 fixedly mounted on the rear of the bottom plate 1; a mounting frame 3 fixedly mounted on the left of the table 2; a straight pipe 4 slidably mounted on the mounting frame 3, the straight pipe 4 can rotate relative to the mounting frame 3 and move up and down to extend into the storage tank 0 for cleaning, and the straight pipe 4 can be connected to a water source; a spray head 5 fixedly mounted on the bottom of the straight pipe 4, the spray head 5 sprays water evenly into the storage tank 0 to assist in cleaning the storage tank 0; a fixing ring 6 fixedly mounted on the bottom of the straight pipe 4; a rotating rod 7 rotatably mounted on the fixing ring 6, and a total of four rotating rods 7 are provided; A brush head 8 is slidably mounted at the bottom of the rotating rod 7, and the brush head 8 can move relative to the rotating rod 7; a spring a9 is fixedly mounted between the brush head 8 and the rotating rod 7, and the spring a9 is used to reset the relative position between the brush head 8 and the rotating rod 7; a moving ring 10 is slidably mounted at the bottom of the straight tube 4, and the moving ring 10 can move up and down relative to the straight tube 4, and the moving ring 10 is located above the fixed ring 6; a connecting arm 11 is correspondingly rotatably mounted between the rotating rod 7 and the moving ring 10; a spring b12 is fixedly mounted between the moving ring 10 and the fixed ring 6, and the spring b12 is sleeved on the straight tube 4.

[0028] The straight tube 4 rotates, and under the action of centrifugal force, the rotating rod 7 will rotate relative to the fixed ring 6, so that the angle between the rotating rod 7 and the straight tube 4 is reduced, and the rotating rod 7 is unfolded. At the same time, the brush head 8 slides relative to the rotating rod 7, so that the overall length of the rotating rod 7 and the brush head 8 is increased, and the brush head 8 is unfolded; in the above process, the rotation of the rotating rod 7 will control the upward movement of the movable ring 10 through the transmission action of the connecting arm 11, and the spring b12 is stretched, that is, the process of unfolding the rotating rod 7 needs to overcome the elastic force of the spring b12, thereby slowing down the unfolding speed of the rotating rod 7. Similarly, the sliding of the brush head 8 relative to the rotating rod 7 also needs to overcome the elastic force of the spring a9, thereby slowing down the extension speed of the brush head 8.

[0029] See also Figure 2 and Figure 4, further comprising: a driving component a arranged on the mounting frame 3, the driving component a being connected to the straight tube 4 to drive the straight tube 4 to move up and down and rotate, the driving component a comprising: a motor a13 fixedly mounted on the mounting frame 3; a gear 14 arranged on the mounting frame 3 and the motor a13, the gear 14 on the mounting frame 3 being rotatably mounted on the mounting frame 3 and slidingly matched with the straight tube 4, so that the gear 14 can control the rotation of the straight tube 4, and the straight tube 4 can move up and down relative to the gear 14, the gear 14 on the motor a13 being fixedly mounted on the output end of the motor a13, and the motor a13 drives the gear 14 Rotate, the above two gears 14 mesh; bracket 15 fixedly mounted on the rear of mounting frame 3; screw 16 rotatably mounted between mounting frame 3 and bracket 15; motor b17 fixedly mounted on the top of bracket 15, the output end of motor b17 is fixed to screw 16 to drive it to rotate; connecting plate 18 disposed between straight tube 4 and screw 16, connecting plate 18 is threadedly connected to screw 16; connecting ring 19 fixedly mounted on the upper end of straight tube 4, connecting ring 19 is rotatably connected to connecting plate 18, and does not separate from connecting plate 18, so that connecting plate 18 controls the vertical movement of straight tube 4 through connecting ring 19.

[0030] See also Figure 5 and Figure 6 , further comprising: a plate 20 fixedly mounted on the table 2, two plates 20 are provided; a mounting base 21 fixedly mounted on the table 2; a turntable 22 rotatably mounted on the mounting base 21, two turntables 22 are provided, the two turntables 22 rotate synchronously but in opposite directions, and the specific directions are as follows Figure 6 As shown, the two turntables 22 are located between the two pallets 20, and arc-shaped limit grooves are arranged on both sides of each turntable 22. The limit grooves are used to limit the position of the storage tank 0 on the turntable 22, and the inner bottom surface of the limit grooves of the turntable 22 is flush with the top surface of the pallet 20, so that the two can cooperate with each other to jointly support the storage tank 0, wherein the limit groove of the left turntable 22 and the left pallet 20 are located directly below the brush head 8; the suction cup 23 fixedly installed in the limit groove of the turntable 22, the suction cup 23 is used to adsorb and fix the storage tank 0, so that the rotation of the turntable 22 can stably transport the storage tank 0; the guide plate 32 fixedly installed on the table 2, the guide plate 32 is arranged between the two turntables 22, and the shape of the guide plate 32 is the moving track of the storage tank 0 when it is transported by the left turntable 22, and the guide plate 32 is used to disengage the storage tank 0 from the suction cup 23 on the right turntable 22, thereby assisting the storage tank 0 to be transferred between the two turntables 22.

[0031] After the storage tank 0 is fixed on the right turntable 22, as the two turntables 22 rotate, the storage tank 0 is transferred between the two turntables 22. During the process, the storage tank 0 enters the limiting groove of the left turntable 22 and is fixed by the suction cup 23 of the left turntable 22. Subsequently, when the storage tank 0 is moved into the range of the guide plate 32, the storage tank 0 will be restricted by the guide plate 32 and can only move along the trajectory when being transported by the left turntable 22. Therefore, the storage tank 0 will be separated from the right turntable 22 and be transported by the left turntable 22 to the bottom of the brush head 8.

[0032] See also Figure 6 , further comprising: a driving assembly b arranged on the mounting seat 21, the driving assembly b is connected to the two turntables 22 to control the two turntables 22 to rotate synchronously and in the opposite direction, and to stop intermittently, the driving assembly b comprises: a worm wheel 24 rotatingly mounted on the mounting seat 21, two worm wheels 24 are provided, and are fixed to the two turntables 22 respectively; a worm 25 rotatingly mounted on the mounting seat 21, the texture of the worm 25 is provided with two sections, the two sections of the texture of the worm 25 are arranged in opposite directions, and the two worm wheels 24 are respectively meshed with the textures at both ends of the worm 25, so that the rotation of the worm 25 drives the two worm wheels 24 to rotate in the opposite direction; a motor c26 fixedly mounted on the table 2, the output end of the motor c26 is fixed to the worm 25, and the motor c26 can control the worm 25 to stop intermittently. The motor a13 is started to control the transmission relationship between the worm 25 and the worm wheel 24, so as to realize the synchronous and opposite rotation mode of the two turntables 22.

[0033] See also Figure 5 , Figure 7 and Figure 8 , further comprising: a top plate 27 fixedly mounted on the mounting base 21, the top plate 27 being located above the left turntable 22, the position of the top plate 27 corresponding to the middle and lower part of the storage tank 0 fixed on the turntable 22, so that when the top plate 27 contacts the storage tank 0, the top plate 27 can change the center of gravity of the storage tank 0, and the storage tank 0 is separated from the suction cup 23 on the turntable 22; a drain rack 28 fixedly mounted on the bottom plate 1, the drain rack 28 being located on the front side of the table 2, the drain rack 28 being low in front and high in the back, and the storage tank 0 separated from the turntable 22 0 will fall on the drain rack 28; a baffle 29 is fixedly installed on the front side of the drain rack 28, and the baffle 29 is used to limit the position of the storage tank 0 on the drain rack 28; a roller 30 is rotatably installed on the drain rack 28, and the rollers 30 are arranged on the drain rack 28, the rollers 30 are low in the front and high in the back, and the straight line connected by all the rollers 30 is inclined, and the position of the left roller 30 is higher than that of the right roller 30; a fan 31 is fixedly installed on the base plate 1, and the fan 31 is located in front of the drain rack 28 and faces the drain rack 28.

[0034] When the left turntable 22 rotates, it will rotate relative to the top plate 27, so that the top plate 27 presses against the storage tank 0 and separates it from the turntable 22. Then the storage tank 0 will fall on the drain rack 28. The inclined drain rack 28 makes the mouth of the storage tank 0 face downward to drain the water therein, and under the action of the roller 30, the storage tank 0 moves to the right.

[0035] Therefore, the complete process of this cleaning device is:

[0036] First, the drive component b is operated to control the turntable 22 to rotate, and the storage tank 0 to be cleaned is placed on the pallet 20 on the right. The storage tank 0 is adsorbed and fixed by the suction cup 23 on the right turntable 22, and is transported by the rotating turntable 22. When the storage tank 0 is moved to the left by the left turntable 22, the storage tank 0 is now located directly below the brush head 8. At this time, the turntable 22 stops intermittently, thereby achieving accurate loading of the storage tank 0.

[0037] Secondly, the driving component a is operated to make the motor b17 control the straight tube 4 to move downward, and the brush head 8 is moved into the storage tank 0. When the bottom of the brush head 8 contacts the inner bottom of the storage tank 0, the spray head 5 sprays the water in the straight tube 4 evenly into the storage tank 0. At the same time, the motor b17 controls the straight tube 4 to rotate, driving the rotating rod 7 and the brush head 8 to rotate. During the process, with the centrifugal force generated by the rotation of the straight tube 4 and the force of the spring a9 and the spring b12 that are constantly overcome, the rotating rod 7 and the brush head 8 are gradually expanded. In addition, the straight tube 4 is still moving downward. Therefore, the brush head 8 can It is able to keep contact with the inner bottom of the storage tank 0 while continuously expanding the cleaning range, that is, to spread the position of the brush head 8 cleaning the inner bottom of the storage tank 0 from the center to the periphery, until the brush head 8 contacts the inner wall of the storage tank 0, and the brush head 8 will no longer rotate relative to the rotating rod 7. At this time, the bottom of the straight tube 4 is close to the inner bottom of the storage tank 0, and the inner bottom of the storage tank 0 has been cleaned. Therefore, after this, the motor b17 controls the screw 16 to rotate forward and reverse, and controls the brush head 8 to move up and down, so that the brush head 8 can clean the inner wall of the storage tank 0, thereby comprehensively cleaning the storage tank 0.

[0038] Finally, after completing the cleaning process of the storage tank 0, the driving component a controls the straight tube 4 to stop rotating and controls the straight tube 4 to move upward, the spring a9 and the spring b12 respectively restore the position of the rotating rod 7 relative to the straight tube 4 and the position of the brush head 8 relative to the rotating rod 7, so that the rotating rod 7 and the straight tube 4 are retracted, and the brush head 8 is taken out from the inner storage tank 0, and then the turntable 22 rotates again to continue to transport the storage tank 0, so that the storage tank 0 is pushed out of the top plate 27 and unloaded and falls on the drain rack 28; the storage tank 0 that falls on the drain rack 28 will be supported by the baffle 29 with the tank mouth facing downward, and the water in the storage tank 0 will be drained from the storage tank 0, and at the same time, the fan 31 blows air into the storage tank 0 to accelerate the evaporation of water, thereby drying the storage tank 0. Not only that, the storage tank 0 will also be moved to the right by the inclined roller 30, so that the storage tanks 0 that are continuously cleaned and transported to the drain rack 28 can be neatly arranged on the drain rack 28 for draining and drying.

[0039] The embodiments of this specific implementation are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. The same components are represented by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
