Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0019] The frame 8 of the PI liquid thawing mixer of the present invention is divided into two areas, that is, the installation area of ​​the roller shaft mechanism on one side and the installation area of ​​the belt pulley transmission mechanism on the other side.

[0020] In the installation area of ​​the roller mechanism, six anti-static rubber rollers in the same direction are divided into upper and lower layers in units of groups. Each roller group includes three anti-static rubber rollers in the same horizontal plane. The three anti-static rubber rollers The roller shafts are set at equidistant intervals, the distance between the middle roller shaft and the roller shafts on both sides is smaller than the diameter of the PI liquid medicine bottle, and the corresponding anti-static rubber roller shafts in the two-l...

Abstract

The invention discloses a PI liquid unfreezing stirrer. The PI liquid unfreezing stirrer comprises a roller shaft mechanism comprising a layer, two layers or multiple layers of roller shaft groups arranged at the same direction; each layer of roller group comprises three antistatic rubber roll shafts in the same horizontal level which are arranged at equal intervals, the three antistatic rubber roll shafts are arranged at equal intervals which are less than the diameter of a PI liquid medicine bottle; corresponding antistatic rubber roll shafts in the two layers or more layers of the roll shaft groups are aligned up and down; middle antistatic rubber roll shafts in the one layer, two layers or three layers of roll shaft groups are connected with a belt wheel drive mechanism so as to form driving roll shafts; antistatic rubber roll shafts at two sides of the driving roll shafts are idle driven roll shafts. The PI liquid unfreezing stirrer provided by the invention can completely unfreeze the PI liquid, effectively homogenize the internal medicine liquid, and prevent the problems of poor membrane thickness, large possibility of spots and hydrolysis chip removal during PI coating.

Description

(1) Technical field: [0001] The invention relates to a bottled liquid homogenization device, in particular to a PI liquid thawing mixer. (2) Background technology: [0002] PI liquid is a chemical liquid used to make LCD alignment film. It is printed on conductive glass and baked to form an alignment film. It can provide a pre-tilt angle for liquid crystal molecules, making the rotation direction of liquid crystal molecules more consistent. [0003] The PI liquid is bottled and frozen when stored, and thawed when used, but the PI liquid is often not fully thawed, resulting in poor film thickness and quality when PI is coated, prone to mottling and hydrolysis desquamation problems. (3) Contents of the invention: [0004] In order to achieve full thawing of PI liquid and uniform stirring, a PI liquid thawing mixer was invented. [0005] The technical scheme of the PI liquid thawing mixer of the present invention includes a roller shaft mechanism. The difference is that the ...
