Description

Technical Field

[0001] The utility model relates to the technical field of water-based ink production equipment, in particular to filtering equipment for water-based ink production. Background Art

[0002] Water-based ink Water-based ink is referred to as water-based ink for short. 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. In the actual production process, it often needs to go through multiple steps, and filtration is one of the more common ones, so as to avoid the final product containing large particles that affect the use effect.

[0003] When using existing filtration equipment for water-based ink production, it generally guides the water-based ink into a device containing a filtration part to achieve the filtration task. However, in actual operation, the intercepted large particles will often continue to cover the filtration part, and some will even be stuck in the holes of the filtration part, thereby affecting the continuous filtration effect of the equipment.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-Figure 5 As shown, the utility model is a filtering device for water-based ink production, including a production filter bin body 1, filter bins 3 are installed on both sides of the production filter bin body 1, and an arc-shaped filter screen 4 is installed on the top of the filter bin 3, and support feet 2 are installed on both sides of the bottom of the production filter bin body 1, and the support feet 2 and the production filter bin body 1 are made in an integrated manner, and threaded holes can be added on the support feet 2 to facilitate the device to be fully fixed in the workshop for use;

[0029] like Figure 4 As shown, a swing mechanism for scraping the particles remaining on the arc filter screen 4 is provided on the production filter bin body 1, and the swing mechanism includes a mounting shaft 5, the mounting shaft 5 passes through one end inside the production filter bin body 1, and a gear 6 is installed at the end of the mounting shaft 5 away from the production filter bin body 1, and an inserted cleaning brush 7 is installed on the top of the outer wall of the mounting shaft 5, and the bristle part of the top of the inserted cleaning brush 7 is elastic and inserted into the filter hole on the arc filter screen 4, and the arc center of the arc filter screen 4 is located on the central axis of the mounting shaft 5, and the mounting shaft 5 is connected to the production filter bin body 1 through a sealed bearing;

[0030] like Figure 2 and Figure 3As shown, a transmission mechanism for driving the swing mechanism to rotate is provided on the production filter bin body 1, and the transmission mechanism includes a guide rod 8, which is installed on one side of the production filter bin body 1, and a special-shaped rack 9 is sleeved on the outer side of the guide rod 8, and the special-shaped rack 9 is slidably connected to the guide rod 8, and the special-shaped rack 9 is meshingly connected to the gear 6, and the reciprocating lateral movement of the special-shaped rack 9 can drive the installation shaft 5 to complete the task of reciprocating rotation;

[0031] like Figure 2 As shown, a driving assembly for driving the transmission mechanism to move is provided on the production filter bin body 1, and the driving assembly includes a mounting plate 10, and a motor 11 is installed on the side of the mounting plate 10 close to the production filter bin body 1, and a rotating shaft 12 is connected to the output end of the motor 11, and the rotating shaft 12 passes through the production filter bin body 1, the filter bin 3 and the special-shaped rack 9 respectively, and a reciprocating screw 13 is installed on the end of the rotating shaft 12 away from the motor 11, and the reciprocating screw 13 and the rotating shaft 12 are made as an integral whole, and the reciprocating screw 13 and the special-shaped rack 9 are threadedly connected, so that when the reciprocating screw 13 rotates, the special-shaped rack 9 can be driven to complete reciprocating lateral movement, and the rotating shaft 12 and the production filter bin body 1 are connected through a sealed bearing;

[0032] Example 2

[0033] like Figure 2 As shown, grinding rollers 14 are evenly installed on the outer sides of the rotating shaft 12 near both ends, and the grinding rollers 14 are located in the corresponding filter bin 3, so that when the rotating shaft 12 drives the reciprocating screw 13 to rotate, the grinding rollers 14 will rotate accordingly and cooperate with the inner wall of the filter bin 3 to complete the grinding action, and the bottom of the filter bin 3 is provided with holes with the same aperture size as the filter holes on the arc filter screen 4.

[0034] The working principle of the utility model is as follows: when in use, the top of the production filter bin body 1 is connected to the water-based ink feeding device, and the bottom of the production filter bin body 1 is connected to the water-based ink subsequent processing device. When the water-based ink falls into the production filter bin body 1 from top to bottom, it will first fall on the arc filter screen 4, and the arc filter screen 4 can filter it. The large particles that cannot pass through the arc filter screen 4 will roll into the filter bins 3 on both sides due to the arc shape of the arc filter screen 4, thereby completing the filtering task;

[0035] At the same time as the above operations, the motor 11 is turned on, and the motor 11 drives the rotating shaft 12 and the reciprocating screw rod 13 to rotate. Through the threaded connection between the special-shaped rack 9 and the reciprocating screw rod 13, and the sliding connection between the special-shaped rack 9 and the guide rod 8, the special-shaped rack 9 can continuously move back and forth laterally at this time, and through the meshing connection between the special-shaped rack 9 and the gear 6, the mounting shaft 5 can continuously rotate back and forth accordingly. At the same time, since the elastic bristles on the top of the inserted cleaning brush 7 are inserted into the holes on the arc-shaped filter screen 4, the inserted cleaning brush 7 can fix the large particles stuck in the holes during the swinging process, and then facilitate it to continue to roll along the arc-shaped filter screen 4 into the filter bins 3 on both sides to avoid affecting the subsequent filtering tasks. At the same time, the rotating shaft 12 will drive the two sets of grinding rollers 14 to rotate, so that the large particles falling into the filter bin 3 will be further ground under the grinding action of the inner walls of the filter bin 3 and the grinding rollers 14, until they pass through the holes of the braking standard on the filter bin 3, thereby completing the further grinding task.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
