Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
Examples
As shown in fig. 1 to 3, the present embodiment provides a double-sided liquid medicine applying device suitable for dry film manufacturing, including a first liquid medicine storage tank 2 and a door-shaped support 1, a first applying roller 3 rotating around a penetrating shaft is installed in the first liquid medicine storage tank 2, a side wall portion of the first applying roller 3 is immersed in the liquid medicine in the first liquid medicine storage tank 2, a second applying roller 4 rotating around the penetrating shaft is installed on the door-shaped support 1, the second applying roller 4 is located right above the first applying roller 3, and a side wall of the second applying roller 4 is in contact with a side wall of the first applying roller 3;
the side wall of the second smearing roller 4 is wrapped by a smearing pad 40, a storage cavity 42 is formed inside the smearing roller, a medicine inlet pipe 43 communicated with the storage cavity 42 is arranged at one end of the smearing roller, and a plurality of medicine outlet holes 41 are formed in the outer wall of the storage cavity 42.
The specific implementation process and principle are as follows:
the first 3 lateral walls submergence of roller of paining is in liquid medicine, and when motor drive first roller 3 of paining rotated, its lateral wall was stained with liquid medicine, and the dry film passes through on its lateral wall that spills first liquid medicine holding vessel 2, and the lower surface is evenly coated and is gone up liquid medicine. The second daubs roller 4 lateral wall and first 3 lateral walls of daubing the roller contact, and the dry film is daubed roller 4 with it and is compressed tightly on first 3 lateral walls of daubing the roller through the second, is convenient for daub liquid medicine fast evenly. Another liquid medicine is injected into the storage cavity 42 from the medicine inlet pipe 43 at the end part of the second smearing roller 4, and the liquid medicine seeps out from the medicine outlet hole 41 to fully soak the smearing pad 40, so that the liquid medicine is coated on the upper surface of the dry film. The second is paintd roller 4 and can be worn to adorn the axle around it and rotate, when the first roller 3 that paints of drive rotates, transmits pulling force forward and the second paints under the effect of roller 3 lateral wall shear stress at the dry film, and roller 4 is paintd to the second also passively, and liquid medicine paints more evenly.
The cylindrical smearing roller is adopted to dip in the liquid medicine, and compared with a common sheet-shaped smearing plate, the smearing force is more uniform, and the hidden trouble of scraping the surface of a dry film does not exist. The upper and lower corresponding first roller 3 and the second roller 4 of paining that sets up, the dry film is scribbled the lateral wall that the roller contacted from two and is passed, and upper and lower both sides are scribbled liquid medicine evenly. Two daub the roller and all work with rotation mode continuity, and the liquid medicine that the lateral wall was stained with and is got distributes more evenly, and it is gentler to paint the dynamics, paints liquid medicine more even.
Further, a concrete mounting mode of the second smearing roller 4 is provided, a square mounting rod 5 penetrates through the cross beam of the door-shaped support 1, the square mounting rod 5 comprises a mounting cross rod 50, two vertical rods 51 and a limiting cross rod 52 extending out of the top surface of the cross beam, the vertical rods 51 are vertically slidably inserted through the cross beam of the door-shaped support 1, and the second smearing roller 4 is rotatably inserted through the mounting cross rod 50. Roller 4 is paintd to the second can rotate around installation horizontal pole 50 under the exogenic motion drives, and montant 51 can slide from top to bottom, avoids the dry film to be compressed tightly excessively when passing through to guarantee that first roller 3 and the second of painting are paintd roller 4 and are all lasted gentle rotation. When the coating process is out of order, the second coating roller 4 may be lifted up to take out the dry film.
Further, the spring 6 is arranged outside the vertical rod 51 in a penetrating manner, and when the spring is in a natural state, the second smearing roller 4 keeps contact with the side wall of the first smearing roller 3. The spring 6 can buffer the pressing force between the two application rollers on one hand and can ensure that the side walls of the two application rollers are always in contact on the other hand.
