Description

Technical Field

[0001] The utility model relates to the technical field of latex powder processing, and specifically relates to a sieving machine for latex powder. Background Art

[0002] Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene / vinyl acetate copolymers, vinyl acetate / versatate copolymers, acrylic acid copolymers, etc. The powder adhesive is made after spray drying, and polyvinyl alcohol is used as a protective colloid. This powder can be quickly redispersed into an emulsion after contact with water. Due to the high bonding ability and unique properties of redispersible latex powder, its diameter size needs to be strictly controlled during the production process. Latex powder with uniform particle size and small particle size is easy to disperse in water, but latex powder with too small particle size is easy to absorb moisture in the air and agglomerate.

In addition, the screening efficiency is low. When only vibration screening is used, the materials cannot be dispersed, and the centralized processing efficiency is low.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content

[0035] In this embodiment, in order to achieve the effect of rapid screening and waste discharge of latex powder, a screening and processing component 4 is designed. A driving motor 4-1 is installed on the top of the shell 1, and a cam 4-2 is connected to the output end. Two sleeves 4-3 are arranged on the top of the shell 1. A movable rod 4-4 that moves left and right is movably connected to the sleeve 4-3. A transmission frame 4-5 is connected between the movable rods 4-4. The transmission frame 4-5 is attached to the outside of the cam 4-2. When the cam 4-2 is controlled to rotate by the driving motor 4-1, the transmission frame 4-5 can be pushed by the convex block to move left and right repeatedly. A connecting seat 4-8 with a concave structure is arranged at one end and the other end of the movable rod 4-4. A movable set in the connecting seat 4-8 is connected to a side frame 4-9, and a supporting spring 4-10 is arranged between the side frame 4-9 and the connecting seat 4-8 to prevent the connection from being affected by vibration.
