Description

Technical Field

[0001] This application relates to the field of printing, and in particular to an ink tank ink recovery device. Background Art

[0002] A printing press refers to a machine for printing text and images. Modern printing presses generally consist of mechanisms such as inking, impression, and paper feeding. The working principle of a printing press is as follows: First, the text and images to be printed are made into a printing plate and installed on the printing press. Then, ink is applied to the areas of the printing plate with text and images, and then directly or indirectly transferred to paper or other substrates, thereby replicating the same printed matter as the printing plate.

[0003] In related technologies, during the printing process of a printing press, due to the too-fast rotation speed of the printing roller, the ink attached to the printing roller will be thrown off by the printing roller, resulting in a considerable waste. To prevent ink waste, generally, an ink tray is set below the printing press to recover the ink. However, the ink will precipitate and solidify after being placed for a period of time and become scrapped.

[0004] Regarding the above related technologies, the inventor believes that the printing press generates heat during operation, and the heat will cause the ink to solidify in a short time, resulting in the scrapping of the ink and making it impossible to recover. Utility Model Content

[0005] To facilitate the operator to recover the ink, this application provides an ink tank ink recovery device.

[0006] The ink tank ink recovery device provided by this application adopts the following technical solutions:

[0007] An ink tank ink recovery device includes a base, an ink box is installed on the base, a liquid storage tank is arranged between the base and the ink box, a delivery pump is installed in the liquid storage tank, a delivery pipe is installed on the delivery pump, the end of the delivery pipe far from the delivery pump is communicated with the ink box, a drain pipe for communicating with the liquid storage tank is installed on the ink box, and an electromagnetic valve is installed on the drain pipe.

[0008] By adopting the above technical solutions, when the electromagnetic valve is opened, the ink in the ink box flows into the liquid storage tank through the drain pipe. Then, the operator starts the delivery pump, and the delivery pump transports the ink in the liquid storage tank to the ink box through the delivery pipe, so that the ink in the ink box always remains in a flowing state, reducing the possibility of the ink solidifying in a short time and facilitating the operator to recover the ink.

[0009] Preferably, a cooling assembly is provided on the base. The cooling assembly includes an electromagnetic pump installed inside the base and a heat exchanger installed on the base. A first connecting pipe and a second connecting pipe for conveying coolant are installed on the electromagnetic pump. The first connecting pipe penetrates through the liquid storage tank and is communicated with the heat exchanger, and the second connecting pipe is communicated with the heat exchanger.

[0010] By adopting the above technical solution, when the electromagnetic pump is started, the coolant circulates in the first connecting pipe, the second connecting pipe and the heat exchanger. When the coolant enters the first connecting pipe, the coolant absorbs the heat of the ink in the liquid storage tank, thereby further reducing the possibility of the ink solidifying due to heat.

A power assembly for driving the rotating rod to rotate is arranged in the liquid storage tank.

[0016] By adopting the above technical solution, the operator makes the rotating rod rotate through the power assembly. The rotation of the rotating rod drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear makes the reciprocating lead screw rotate. The rotation of the reciprocating lead screw drives the push plate to reciprocate.

[0017] Preferably, a connection box is provided on the base, an installation box is provided inside the connection box, the power assembly includes a worm rotatably installed on the inner side wall of the installation box, a worm gear sleeved on the end of a rotating rod extending into the installation box, and a fan blade fixedly installed on the worm. A third communication pipe for communicating with the bottom of the installation box is installed on the electromagnetic pump, and the first communication pipe communicates with the top of the installation box.

[0018] By adopting the above technical solution, when the coolant enters the installation box through the third communication pipe, the coolant impacts the fan blade to make the worm rotate, the rotation of the worm drives the worm gear to rotate, and the rotation of the worm gear makes the rotating rod rotate, ultimately realizing the reciprocating movement of the pushing plate.

[0019] Preferably, a filter plate is installed in the ink cartridge, and a plugging groove for plugging and cooperating with the filter plate is opened on the ink cartridge.

[0020] By adopting the above technical solution, the setting of the plugging groove facilitates the operator to position the filter plate, and the setting of the filter plate is beneficial to preventing impurities in the ink cartridge from entering the liquid storage tank along with the ink.

[0021] Preferably, a positioning groove is opened on the filter plate, a spring is fixedly connected to the inner end face of the positioning groove, and an elastic ball for abutting against the inner bottom face of the plugging groove is fixedly connected to the end of the spring away from the inner end face of the positioning groove.

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 for a more detailed description.

[0033] The embodiment of the present application discloses an ink tank ink recovery device. Referring to Figure 1 , the ink tank ink recovery device includes a base 1, a liquid storage tank 2, and an ink cartridge 3.

[0034] Referring to Figure 1 , Figure 2 , the base 1 is in the shape of a hollow box and is horizontally arranged. The liquid storage tank 2 is also in the shape of a hollow box, and the liquid storage tank 2 is fixedly installed on the upper surface of the base 1. The ink cartridge 3 is fixedly installed on the upper surface of the liquid storage tank 2. Drain pipes 31 are installed at both ends of the ink cartridge 3. One end of the drain pipe 31 is communicated with the inner cavity of the ink cartridge 3, and the other end of the drain pipe 31 extends into the liquid storage tank 2, and a solenoid valve 32 is installed at the end of the drain pipe 31 located in the liquid storage tank 2.

[0035] Referring to Figure 1 , Figure 2 , a transfer pump 21 is arranged in the middle of the liquid storage tank 2. The transfer pump 21 is fixedly installed on the inner bottom surface of the liquid storage tank 2, and a transfer pipe 22 is installed on the transfer pump 21. The transfer pipe 22 extends upward to the top of the ink cartridge 3, and the transfer pipe 22 is communicated with the inner cavity of the ink cartridge 3.

[0036] When the operator opens the solenoid valve 32, the ink in the ink cartridge 3 can flow into the liquid storage tank 2 through the liquid discharge pipe 31. Then the operator starts the delivery pump 21, and the delivery pump 21 transports the ink in the liquid storage tank 2 to the ink cartridge 3 through the delivery pipe 22, so that the ink in the ink cartridge 3 and the ink in the liquid storage tank 2 achieve circular flow, reducing the possibility of the ink solidifying in a short time and facilitating the operator to recycle the ink.

[0037] Refer to Figure 2 , a cooling component 4 is arranged on the base 1. The cooling component 4 includes an electromagnetic pump 41 and a heat exchanger 42.

The connecting box 5 is a hollow box body.

[0038] Refer to Figure 2 , an installation box 51 is fixedly installed on the inner side wall of the connecting box 5. One end of the third connecting pipe 44 is communicated with the electromagnetic pump 41, and the other end of the third connecting pipe 44 penetrates through the connecting box 5 and is communicated with the bottom of the installation box 51. The top of the installation box 51 is communicated with a first connecting pipe 45. The end of the first connecting pipe 45 away from the installation box 51 penetrates into the liquid storage tank 2, and the part of the first connecting pipe 45 located in the liquid storage tank 2 is spirally wound around the delivery pipe 22. The end of the first connecting pipe 45 passing through the liquid storage tank 2 is communicated with the heat exchanger 42. One end of the second connecting pipe 43 is communicated with the heat exchanger 42, and the other end of the second connecting pipe 43 is communicated with the electromagnetic pump 41. Coolant flows in the first connecting pipe 45, the second connecting pipe 43, and the third connecting pipe 44.

[0039] The operator starts the electromagnetic pump 41, and the electromagnetic pump 41 enables the coolant to circulate in the first connecting pipe 45, the second connecting pipe 43, the third connecting pipe 44, and the heat exchanger 42. The coolant can effectively reduce the temperature of the ink in the liquid storage tank 2, thereby reducing the possibility of the ink solidifying due to heat.

[0040] Refer to Figure 2, a push plate 33 is arranged inside the ink cartridge 3. The push plate 33 is slidably matched with the inner side wall of the ink cartridge 3. The arrangement of the push plate 33 facilitates the operator to make the ink in the ink cartridge 3 enter the liquid storage tank 2 through the liquid discharge pipe 31. A driving assembly 6 is arranged on the ink cartridge 3. The driving assembly 6 includes a reciprocating lead screw 61 and a rotating rod 62. The length direction of the reciprocating lead screw 61 is consistent with the length direction of the ink cartridge 3. One end of the reciprocating lead screw 61 is rotatably matched with the ink cartridge 3, and the other end of the reciprocating lead screw 61 extends into the connection box 5. The rotating rod 62 is arranged in the connection box 5 and is vertically arranged. The top of the rotating rod 62 is rotatably connected to the inner top surface of the connection box 5. A first bevel gear 63 is fixedly sleeved on the rotating rod 62, and a second bevel gear 64 is fixedly sleeved on the end of the reciprocating lead screw 61 located in the connection box 5. The first bevel gear 63 and the second bevel gear 64 are meshed with each other.

[0041] Referring to Figure 2 , a power assembly 7 is arranged inside the installation box 51. The power assembly 7 includes a worm 71, a worm gear 72 and a fan blade 73. The worm 71 is horizontally arranged inside the installation box 51 and is rotatably matched with the inner side wall of the installation box 51. The bottom of the rotating rod 62 extends into the installation box 51 and is rotatably matched with the installation box 51. The worm gear 72 is fixedly sleeved on the end of the rotating rod 62 located inside the installation box 51, and the worm 71 is meshed with the worm gear 72.

The two fan blades 73 are symmetrically arranged about the axis of the worm 71, and the coolant can impact the fan blades 73 and make the fan blades 73 rotate when passing through the installation box 51.

[0042] When the coolant enters the installation box 51 through the third communication pipe 44, the coolant impacts the fan blades 73 to make the worm 71 rotate. The worm 71 and the worm gear 72 cooperate to drive the rotating rod 62 to rotate. The rotating rod 62 drives the reciprocating lead screw 61 to rotate through the cooperation of the first bevel gear 63 and the second bevel gear 64. The rotation of the reciprocating lead screw 61 finally realizes the reciprocating movement of the push plate 33, so that the ink in the ink cartridge 3 is circulated at an accelerated speed.

[0043] Referring to Figure 2 , Figure 3 , filter plates 34 for filtering impurities in the ink are installed at both ends of the ink cartridge 3. Plug-in slots 35 are opened at both ends of the ink cartridge 3. The plug-in slots 35 correspond to the filter plates 34 one by one, and the filter plates 34 are slidably matched with the inner side walls of the plug-in slots 35. A positioning groove 36 is opened on the side wall of the filter plate 34. The opening of the positioning groove 36 is circular. A spring 37 is fixedly connected to the inner end surface of the positioning groove 36.

The elastic ball 38 can extend out of the positioning groove 36 and abut against the inner bottom surface of the plug-in slot 35. The cooperation of the spring 37 and the elastic ball 38 can fix the position of the filter plate 34 and improve the installation stability of the filter plate 34.

[0044] The implementation principle of the ink tank ink recovery device in the embodiment of the present application is as follows: The operator starts the delivery pump 21 and opens the solenoid valve 32. The ink in the ink cartridge 3 flows into the liquid storage tank 2 through the liquid discharge pipe 31, and the delivery pump 21 then transports the ink in the liquid storage tank 2 to the ink cartridge 3 through the delivery pipe 22, so that the ink in the ink cartridge 3 always remains in a flowing state, reducing the possibility of the ink solidifying in a short time and facilitating the operator to recover the ink.

[0045] The operator starts the electromagnetic pump 41, and the electromagnetic pump 41 makes the coolant circulate in the first connecting pipe 45, the second connecting pipe 43, the third connecting pipe 44 and the heat exchanger 42. On the one hand, the coolant can effectively reduce the temperature of the ink in the liquid storage tank 2, thereby reducing the possibility of the ink solidifying due to heat. On the other hand, the coolant can impact the fan blade 73 to make the worm 71 rotate. Through the cooperation of the worm 71, the worm gear 72, the rotating rod 62, the first bevel gear 63, the second bevel gear 64 and the reciprocating screw rod 61, the reciprocating movement of the pushing plate 33 is finally realized, so that the ink in the ink cartridge 3 circulates at an accelerated speed.
