Description

Technical Field

[0001] This utility model relates to the field of recycling and reuse technology, and discloses a device for recycling and reusing water-based inks. Background Technology

[0002] Water-based inks are environmentally friendly printing inks that use water as a solvent. They are mainly composed of water, pigments, resins, and additives, and are characterized by low volatility, non-toxicity, and strong adhesion. They are widely used in packaging printing, label printing, and paper printing.

[0003] Patent publication number CN222004750U discloses an ink circulation device for decorative paper printing, including an ink tank. A printing plate roller is mounted on top of the ink tank, and mounting plates for mounting the printing plate roller are symmetrically arranged on both sides of the ink tank. A motor for driving the printing plate roller is mounted on one side of each mounting plate. An inkjet assembly is mounted on one side of the ink tank, and a doctor blade assembly is movably mounted on top of the inkjet assembly. A ramp is located on the top of the ink tank away from the doctor blade assembly, and a cleaning assembly is mounted on top of the ramp. Although the above patent can effectively remove residual ink and dust from the surface of the printing plate roller through the cooperation of the doctor blade assembly and the cleaning assembly, thereby improving the printing quality of decorative paper, the ink, after filtering into the ink tank, is prone to pigment sedimentation if not stirred, leading to decreased ink uniformity. Furthermore, the stagnant ink surface may form a skin due to oxidation or volatilization, affecting subsequent printing results.

[0004] Therefore, a water-based ink recycling and reuse device with stirring function is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, such as the tendency of pigments to settle and ink uniformity to decrease after the ink is filtered and enters the ink tank without stirring, and the possibility of skin formation on the surface of the stagnant ink due to oxidation or volatilization, which affects the subsequent printing effect, this utility model provides a water-based ink recycling and reuse device with stirring function.

[0006] The technical solution of this utility model is as follows: a water-based ink recycling and reuse device, including a recycling tank, a feed barrel, filter cotton, a handle, a water pump, a connecting pipe, and a discharge pipe. The feed barrel is threaded on the top left side of the recycling tank, and filter cotton is installed in the lower part of the feed barrel. A handle is fixedly connected to the outside of the feed barrel. A water pump is installed on the top right side of the recycling tank, and a connecting pipe is connected to the right side of the water pump. The lower end of the connecting pipe is connected to the recycling tank. The discharge pipe is connected to the top of the water pump. The device also includes a motor and a stirring rod. The motor is installed in the middle of the top of the recycling tank, and a stirring rod is rotatably installed inside the recycling tank. The output shaft of the motor is connected to the stirring rod through a coupling.

[0007] As a preferred technical solution of this utility model, it also includes a fixing plate, a controller, a thermostatic tube and a temperature monitor. The fixing plate is fixedly connected to the front side of the recycling tank, two controllers are installed on the front side of the fixing plate, and a thermostatic tube is connected to the rear side of the two controllers. The thermostatic tube is wound inside the recycling tank. The temperature monitor is installed on the front side of the fixing plate and is electrically connected to the controller.

[0008] As a preferred technical solution of this utility model, it also includes a support bucket, a clamping plate, a first filter plate and a second filter plate. Two clamping plates are clamped to the top of the recycling tank, and the two clamping plates are fixedly connected to the support bucket.

[0010] As a preferred technical solution of this utility model, it also includes a protective shell, which is snapped onto the right side of the top of the recycling tank, and the water pump is located inside the protective shell.

[0011] As a preferred technical solution of this utility model, it also includes anti-slip sleeves, with two anti-slip sleeves fitted on the handle.

[0012] Compared with the prior art, this utility model provides a water-based ink recycling and reuse device, which has the following beneficial effects: 1. By starting the motor, the output shaft of the motor rotates to drive the stirring rod to rotate, continuously stirring the ink in the recycling tank, so as to fully prevent pigment precipitation, maintain the uniformity of ink, and effectively reduce the occurrence of skinning, thereby improving the recycling quality.

[0013] 2. The controller automatically adjusts the heating or cooling function of the thermostatic tube based on real-time temperature data, so that the thermostatic tube regulates the temperature of the entire tank, ensuring that the ink is maintained within a suitable temperature range, avoiding low-temperature condensation or high-temperature volatilization, thereby ensuring ink stability.

[0014] 3. The ink first enters the support tank, where the first filter plate filters out larger impurities. Then, the ink passes through the second filter plate for secondary filtration, further removing finer impurities and thus improving the cleanliness of the ink. Attached Figure Description

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0022] Example 1: Water-based ink recycling and reuse device, please refer to Figures 1-5 The system includes a recycling tank 1, a feed hopper 2, a filter cotton 3, a handle 4, a water pump 7, a connecting pipe 8, and a discharge pipe 9. The feed hopper 2 is threaded on the top left side of the recycling tank 1. The filter cotton 3 is installed in the lower part of the feed hopper 2. The handle 4 is fixedly connected to the outside of the feed hopper 2. The water pump 7 is installed on the top right side of the recycling tank 1. The connecting pipe 8 is connected to the right side of the water pump 7. The lower end of the connecting pipe 8 is connected to the recycling tank 1. The discharge pipe 9 is connected to the top of the water pump 7. The motor 5 is installed in the middle of the top of the recycling tank 1. The stirring rod 6 is rotatably installed inside the recycling tank 1. The output shaft of the motor 5 is connected to the stirring rod 6 through a coupling. The protective shell 19 is snapped on the top right side of the recycling tank 1. The water pump 7 is located inside the protective shell 19 to protect the water pump 7 from external interference. Two anti-slip sleeves 20 are fitted on the handle 4 to increase the friction between the hands and prevent the hands from slipping when disassembling the feed hopper 2.

[0023] When the device is needed, the used water-based ink is poured into the recycling tank 1 through the feed tank 2. The ink is first filtered through the filter cotton 3 to remove impurities such as paper scraps, suspended particles, fibers, and dust, ensuring the cleanliness of the ink entering the recycling tank 1. After the filtered ink enters the recycling tank 1, the motor 5 is started. The output shaft of the motor 5 rotates to drive the stirring rod 6 to rotate, continuously stirring the ink in the recycling tank 1 to prevent pigment sedimentation, maintain the uniformity of the ink, and effectively reduce the occurrence of skinning, thereby improving the recycling quality. After the processing is completed, the water pump 7 is started. The water pump 7 draws the filtered ink from the bottom of the recycling tank 1 through the connecting pipe 8, pressurizes it, and then transports it to external equipment through the discharge pipe 9 for recycling, thereby reducing production costs.

[0024] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 4 A fixing plate 10 is fixedly connected to the front side of the recycling tank 1. Two controllers 11 are installed on the front side of the fixing plate 10. A thermostatic tube 12 is connected to the rear side of the two controllers 11. The thermostatic tube 12 is wound inside the recycling tank 1. A temperature monitor 13 is installed on the front side of the fixing plate 10. The temperature monitor 13 is electrically connected to the controllers 11.

[0025] When the filtered ink enters the recycling tank 1, the temperature monitor 13 is activated. The temperature monitor 13 monitors the ink temperature in real time and feeds the data back to the controller 11. The controller 11 automatically adjusts the heating or cooling function of the thermostat tube 12 according to the real-time temperature data, so that the thermostat tube 12 regulates the temperature of the entire tank, ensuring that the ink is maintained within a suitable temperature range, avoiding low-temperature condensation or high-temperature volatilization, thereby ensuring the stability of the ink.

[0026] Please see Figure 1 and Figure 5 The top of the recycling tank 1 is fitted with two clamping plates 15, which together fix a support tank 14. A first filter plate 16 is clamped inside the support tank 14, and a second filter plate 17 is embedded at the bottom of the support tank 14. A pull rod 18 is fixedly connected between the support tank 14 and the clamping plates 15. The clamping plates 15 and the pull rod 18 facilitate the disassembly and cleaning of the support tank 14, thus maintaining the filtration effect.

[0027] Before entering the feed tank 2, the used water-based ink first enters the support tank 14. The first filter plate 16 filters out larger impurities in the ink. Then, the ink undergoes secondary filtration through the second filter plate 17 to further remove fine impurities, thereby improving the cleanliness of the ink.

[0028] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
