[0002] Water-based ink is abbreviated as water-based ink. Flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. Water-based ink is particularly suitable for packaging and printing products with strict hygiene requirements such as tobacco, alcohol, food, beverages, medicines, and children's toys.

[0003] The existing water-based ink storage device has a simple structure, consisting of only a can, and has poor heat insulation effect, which causes the water-based ink to be in a static state during long-term storage and is prone to ink separation. At the same time, the water-based ink is easily deteriorated by changes in external temperature, affecting its use. In view of this, we propose a water-based ink storage device.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Example:

[0024] This embodiment discloses a water-based ink storage device, see Figures 1 to 5 , comprising a tank body 1, on which a stirring mechanism 2 is provided.

[0025] Specifically, Figure 4 As shown, the tank body 1 includes a tank shell 101, an inner liner 102 is arranged in the tank shell 101, and an insulation layer 103 is filled between the tank shell 101 and the inner liner 102, wherein the tank shell 101 is used to protect the entire water-based ink storage device, the inner liner 102 is used to hold the water-based ink, and the insulation layer 103 is used to reduce the influence of the external temperature on the water-based ink.

[0026] Further, such as Figures 1 to 3 As shown, the tank shell 101 is provided with a feed valve 3 along one side of the reciprocating component 203 for filling water-based ink, and the tank shell 101 is provided with a pressure relief component 104 along one side of the feed valve 3 .

[0027] Further, if Figures 1 to 3As shown, the pressure relief assembly 104 includes a sleeve 1041 with an open bottom, a piston 1042 and a spring 1043. The bottom of the sleeve 1041 is penetrated through the top of the tank shell 101 and communicated with the inner cavity at the top of the liner 102. The piston 1042 is arranged in the inner cavity of the sleeve 1041. The side of the piston 1042 is connected to the inner wall of the sleeve 1041. One end of the spring 1043 is fixedly connected to the top of the piston 1042, and the other end of the spring 1043 is fixedly connected to the inner wall of the top of the sleeve 1041. An exhaust pipe 1044 communicating with the inner cavity in the middle of the sleeve 1041 is opened on one side of the sleeve 1041. The exhaust pipe 1044 The other end is inclined downward, and the stirring mechanism 2 is likely to produce more gas during the stirring process, which is likely to cause the air pressure and temperature inside the tank body 1 to increase. At this time, the gas inside the tank body 1 pushes the piston 1042 upward to move the piston 1042 toward the top of the sleeve 1041 and compress the spring 1043, until the piston 1042 moves to the top of the connecting end of the exhaust pipe 1044 and the sleeve 1041, the air pressure inside the tank body 1 can be discharged from the exhaust pipe 1044. When the air pressure inside the tank body 1 is stable, the spring 1043 resets and drives the piston 1042 to drop to the bottom of the sleeve 1041 to maintain the sealing of the tank body 1.

[0028] It is worth noting that if Figure 1 , Figure 4 As shown, a discharge valve 4 communicating with the inner cavity at the bottom of the inner container 102 is provided at the bottom of the tank shell 101 for discharging the aqueous ink.

[0029] Specifically, Figure 1 , Figure 4 , Figure 5 As shown, the stirring mechanism 2 includes a C-shaped mounting frame 201, a motor 202, a reciprocating assembly 203 and a rotating shaft 204. The two ends of the bottom of the C-shaped mounting frame 201 are fixedly connected to the outer wall of the top of the tank shell 101. The motor 202 is penetrated through the top of the C-shaped mounting frame 201, and the reciprocating assembly 203 is arranged at the output end of the motor 202. One end of the rotating shaft 204 is penetrated through the top of the tank shell 101 and extends to the inner cavity at the bottom of the liner 102. The output end of the motor 202 is transmitted through the reciprocating assembly 203 and the other end of the rotating shaft 204. The rotating shaft 204 is fixedly installed with a plurality of stirring rods 205 along the surface of the inner cavity of the liner 102 by screws. The motor 202 is driven by an external control mechanism. The motor 202 drives the rotating shaft 204 and the stirring rod 205 to reciprocate in the inner cavity of the liner 102 through the reciprocating assembly 203 to prevent ink separation.

[0030] Further, such as Figure 5As shown, the reciprocating assembly 203 includes a gear 2031 and a collar 2032. The gear 2031 is fixedly connected to the other end of the rotating shaft 204. The top of the collar 2032 is fixedly connected to the output end of the motor 202. The bottom side of the collar 2032 extends downward and covers the surface of the gear 2031. The inner wall of one side of the bottom of the collar 2032 is provided with teeth 2033. The surface of the gear 2031 is meshed with the teeth 2033. The inner wall of the top of the collar 2032 is fixedly connected to a semi-toothed gear 2031. 034, the half-toothed gear 2034 is meshed with the gear 2031, the motor 202 drives the sleeve ring 2032 to rotate, the sleeve ring 2032 drives the half-toothed gear 2034 to rotate, when the surface of the gear 2031 is meshed with the teeth 2033, the rotating shaft 204 is driven to rotate in the forward direction, and when the toothed gear 2034 is meshed with the gear 2031, the rotating shaft 204 is driven to rotate in the reverse direction. The reciprocating stirring method can prevent the stirring mechanism from rotating in one direction for a long time to produce a centrifugal effect, resulting in ink separation.

[0031] Further, if Figure 5 As shown, the tooth end of the half-toothed gear 2034 is on the opposite side of the tooth 2033, the smooth side surface of the half-toothed gear 2034 is opposite to the tooth 2033, and the half-toothed gear 2034 and the ring 2032 rotate coaxially to ensure the stability of the movement of the reciprocating component 203.

[0032] Working principle: When the utility model is used, water-based ink is stored in the tank body 1 through the feed valve 3, the tank shell 101 is used to protect the entire water-based ink storage device, the liner 102 is used to hold the water-based ink, and the insulation layer 103 never reduces the influence of the external temperature on the water-based ink. After the ink is placed for a long time, the motor 202 is driven by the external control mechanism, the motor 202 drives the ring 2032 to rotate, the ring 2032 drives the half-toothed gear 2034 to rotate, when the surface of the gear 2031 is meshed with the teeth 2033, the shaft 204 is driven to rotate forward, and when the half-toothed gear 2034 is meshed with the gear 2031, the shaft 204 is driven to rotate reversely, thereby driving the rotating shaft 204 to rotate. The shaft 204 and the stirring rod 205 reciprocate in the inner cavity of the inner liner 102 to prevent ink separation. The stirring mechanism 2 is likely to generate more gas during the stirring process, which can easily cause the air pressure and temperature inside the tank body 1 to increase. At this time, the gas inside the tank body 1 pushes the piston 1042 upward to move the piston 1042 toward the top of the sleeve 1041 and compress the spring 1043 until the piston 1042 moves to the top of the connecting end of the exhaust pipe 1044 and the sleeve 1041. The air pressure inside the tank body 1 can be discharged from the exhaust pipe 1044. When the air pressure inside the tank body 1 is stable, the spring 1043 resets and drives the piston 1042 to drop to the bottom of the sleeve 1041 to maintain the sealing of the tank body 1.
