Description

Technical Field

[0001] This utility model relates to the field of ink printing unit cleaning technology, specifically to a water-based ink printing unit cleaning and circulation device. Background Technology

[0002] In the modern printing industry, water-based inks are widely used due to their environmentally friendly characteristics. After the printing unit uses water-based inks, the residual ink in the ink supply system needs to be cleaned. The existing water-based ink printing unit circulation device consists of a water pump, a delivery pipe, a return pipe, and an integrated housing.

[0003] Due to the non-separable structural design of the cabinet, the cleaning method for the inside of the cabinet is limited to water rinsing. However, this method is difficult to reach the dead corners inside the cabinet and has no effective effect on removing dried or tightly adhered residual ink. As a result, ink residue is always present inside the cabinet, which not only affects the purity and circulation effect of the subsequent cleaning solution, but also greatly reduces the overall cleaning quality and fails to meet the cleanliness requirements of the printing unit for the cleaning solution. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning and circulation device for water-based ink printing units to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-based ink printing unit cleaning and circulation device, comprising a first box, a second box and a locking mechanism, wherein a water pump is fixedly installed on one side of the first box, a delivery pipe is fixedly connected to the water outlet of the water pump, and a return water pipe is fixedly connected to the front wall of the first box.

[0006] The locking mechanism includes a pressure rod, a connecting groove, a connecting frame, and a positioning frame. Each positioning frame has a rubber pad fixedly connected to its bottom end. A fixed frame is slidably connected to the pressure rod. Symmetrically arranged locking rods are fixedly connected to the fixed frame. Each locking rod has a locking groove. An oblique groove is opened at the bottom end of each locking rod corresponding to the locking groove. A sealing gasket is fixedly connected to one side of the connecting frame.

[0007] Preferably, a filter screen is fixedly connected inside the box, and a water inlet is fixedly connected to the top of the box.

[0008] Preferably, the pump's pumping end is fixedly connected to the side wall of a tank.

[0009] Preferably, the pressure rod is fixedly connected to the first box and the second box respectively, the connecting groove is opened inside one side of the first box, the connecting frame is fixedly connected to one side of the second box, and the positioning frame is slidably connected to the top of the first box and the second box respectively.

[0010] Preferably, the sealing gasket and the connecting frame are both slidably connected inside the connecting groove, and the positioning frame and the rubber pad are both slidably connected inside the slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the original integrated box is split into a separable one-box and two-box structure, and with the help of a locking mechanism, the two boxes can be tightly fitted and firmly fixed, effectively eliminating gaps at the connection and preventing the problem of cleaning fluid leakage from the root. When it is necessary to disassemble for cleaning, only the core component of the locking mechanism needs to be pulled out to quickly release the fixed state of the two boxes. The operation is simple and convenient and does not require complicated tools.

[0012] After the two boxes are completely separated, staff can directly clean key areas such as the inner wall of the box, corner welds, and pipe interfaces, easily removing dried residual ink and greatly improving the thoroughness and cleanliness of the internal cleaning, thus providing a reliable guarantee for the purity of the subsequent cleaning solution circulation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The present invention provides the following technical solution:

[0019] Example 1: A water-based ink printing unit cleaning and circulation device includes a first box 1, a second box 2, and a locking mechanism 3. A water pump 4 is fixedly installed on one side of the first box 1. A delivery pipe 5 is fixedly connected to the water outlet of the water pump 4. A return water pipe 6 is fixedly connected to the front wall of the first box 1. The locking mechanism 3 includes a pressure rod 31, a connecting groove 32, a connecting frame 33, and a positioning frame 34. A rubber pad 35 is fixedly connected to the bottom of each positioning frame 34. A fixed frame 36 is slidably connected to the pressure rod 31. A symmetrically arranged locking rod 37 is fixedly connected to the fixed frame 36. A locking groove 38 is opened on each locking rod 37. An oblique groove 39 is opened on each locking rod 37 at the bottom position corresponding to the locking groove 38. A sealing gasket 301 is fixedly connected to one side of the connecting frame 33.

[0020] The pump 4 is fixedly connected to the side wall of the first tank 1. The pressure rod 31 is fixedly connected to the first tank 1 and the second tank 2 respectively. The connecting groove 32 is opened inside one side of the first tank 1. The connecting frame 33 is fixedly connected to one side of the second tank 2. The positioning frame 34 is slidably connected to the top of the first tank 1 and the second tank 2 respectively. The sealing gasket 301 and the connecting frame 33 are both slidably connected inside the connecting groove 32. The positioning frame 34 and the rubber gasket 35 are both slidably connected inside the slot 38.

[0021] In use, the delivery pipe 5 can be connected to the ink tank in the ink supply system, and the return water pipe 6 can be connected to the inkjet tube on the ink tank. Then, the water pump 4 is started, and the water pump 4 will transport the water from the first tank 1 and the second tank 2 to the inside of the ink tank through the delivery pipe 5. The water that has rinsed the ink tank will then return to the inside of the first tank 1 and the second tank 2 through the inkjet tube and the return water pipe 6. This process can be repeated to clean them. After use, impurities will accumulate inside the first tank 1 and the second tank 2. At this time, push the positioning frame 34 forcefully. The rubber pad 35 at the bottom of the positioning frame 34 is in a compressed state. Therefore, the positioning frame 34 and the rubber pad 35 slide in the slot 38 with great friction. When the positioning frame 34 separates from the slot 38, the limiting position of the fixing frame 36 is released. Move the fixing frame 36 upward and separate it from the two pressure rods 31. At this time, the locking of the first tank 1 and the second tank 2 is released, and the second tank 2 can be dragged directly away from the first tank 1. The second tank 2 will drive the connecting frame 33. The sealing gasket 301 separates from the connecting groove 32 on the first box 1. The connection between the sealing gasket 301 and the connecting groove 32 prevents the connection between the first box 1 and the second box 2 from separating. At this time, the inside of the first box 1 and the second box 2 can be cleaned. The cleaning is convenient and easy to clean without dead corners, improving the cleanliness of the first box 1 and the second box 2. When locking is required, the first box 1 and the second box 2 are reconnected. The fixing frame 36 is connected to the two pressure rods 31. The locking rod 37 on the fixing frame 36 will correspond to the positioning frame 34. Then, the positioning frame 34 is moved into the slot 38 with force. At this time, the rubber pad 35 at the bottom of the positioning frame 34 will abut against the inclined groove 39. During the process of the rubber pad 35 entering the slot 38, the rubber pad 35 is continuously squeezed. When the positioning frame 34 and the rubber pad 35 are completely in the slot 38, the rubber pad 35 is compressed. At this time, the positioning frame 34 cannot separate from the slot 38 without the influence of external force. The first box 1 and the second box 2 are fixed.

[0022] Example 2: The technical solution of this example that differs from that of Example 1 includes: a filter screen 7 is fixedly connected inside a box 1, and a water inlet 8 is fixedly connected to the top of a box 1;

[0023] During use, the inlet 8 facilitates the addition of water to the first tank 1 and the second tank 2, and the filter screen 7 can filter the cleaning water that enters the first tank 1 and the second tank 2 through the return water pipe 6.
