Description

Technical Field

[0001] The utility model relates to the field of acrylic resin production, in particular to a quantitative feeding mixer for acrylic resin production. Background Art

[0002] At present, when producing acrylic resin, it is generally necessary to add some liquid catalysts or additives to the equipment. Usually, a variety of materials are pre-proportioned and then put into the equipment.

[0003] Chinese patent number CN214810667U records a feeding device for acrylic resin production, which mainly includes a feeding shell and a feeding tank. A feeding disk is rotatably installed inside the feeding shell. A bracket is welded and fixed to the front end surface of the feeding shell. A turntable is rotatably installed on the bracket. The turntable is fixedly connected to one side of the feeding disk rotatably installed in the feeding shell through a rotating shaft. A feeding pipe is fixed on the top of the feeding shell, and a feeding tank is fixed on the top of the feeding pipe. It can intermittently and evenly feed liquid materials into the equipment, and the amount of each feed is the same.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, it is necessary to rotate the screw rod to push the first piston to slide in the adjusting cylinder, wherein the first piston and the second piston are not directly connected, and the first piston moves the second piston through hydraulic oil, which makes the second piston only move to the left, and it cannot move to the right. When adding materials, it can only be manually filled into the adjusting cylinder, and the overall operation is relatively complicated. For this reason, we designed a quantitative feeding mixer for acrylic resin production. Utility Model Content

[0005] In order to solve the technical problem that the second piston can only move to the left but not to the right and can only be manually filled into the regulating cylinder when adding materials is needed, the utility model provides a quantitative feeding mixer for acrylic resin production.

[0006] The utility model is implemented by the following technical scheme: a quantitative feeding mixer for acrylic resin production, comprising a feeding barrel, a mixing box and a feeding cylinder, wherein two feeding barrels are provided, and a piston is slidably and sealedly provided inside the two feeding barrels, the feeding cylinder is installed at the right end of the feeding barrel, and a push rod of the feeding cylinder slides through the right side of the feeding barrel and is connected with the piston, the mixing box is arranged in the middle position below the two feeding barrels, and the left end of the feeding barrel is connected with the inside of the mixing box through a discharge pipe, and a discharge pipe is arranged below the right end of the mixing box.

[0007] As a further improvement of the above scheme, the outer ring surfaces of the two adding barrels are inlaid with acrylic plates on the outward side to form observation windows, and the outer ring surfaces of the adding barrels are also provided with scale lines. The moving position of the piston can be clearly seen through the observation window, and the movement amount of the piston can be clearly observed through the scale lines, thereby knowing the amount of liquid added.

[0008] As a further improvement of the above scheme, a one-way valve is arranged on the discharge pipe, and the liquid flows in the one-way valve from top to bottom. The materials in the liquid can only enter the mixing box through the one-way valve from top to bottom, so that the mixed liquid in the mixing box will not enter the corresponding feeding barrel, thereby ensuring the purity of the material inside the feeding barrel.

[0009] As a further improvement of the above scheme, a storage barrel is respectively arranged above the two feeding barrels, and the bottom of the storage barrel is connected with the upper left end of the feeding barrel through a feeding pipe, and a solenoid valve is also arranged on the feeding pipe. The storage barrel is used to store corresponding materials, and can be replenished in time when the material inside the feeding barrel is insufficient.

[0010] As a further improvement of the above scheme, the two solenoid valves are controlled by two independent power supplies, and the two feeding cylinders are controlled by two separate power supplies, which can replenish the materials inside the two feeding cylinders respectively and can mix two different materials respectively.

[0011] As a further improvement of the above scheme, the mixing box is of cylindrical structure, and transmission shafts are rotatably installed on the left and right sides of the mixing box through bearings, and the left end of the transmission shaft is connected to the output shaft of the mixing motor through a coupling. The mixing motor can rotate the transmission shaft, thereby fully mixing the materials inside the mixing box;

[0012] The transmission shaft is provided with a spiral blade, the outer ring surface of the spiral blade is in sliding contact with the inside of the mixing box, and the rotating spiral blade can mix the materials inside and simultaneously move the materials to the right and be discharged through the discharge pipe.

[0013] As a further improvement of the above scheme, three mixing plates are arranged in the gap of the spiral blades, and the three mixing plates are distributed in a ring shape. The structure of the mixing plates is an L-shaped structure. The outer ring surface of the mixing plates is designed to be arc-shaped and is in rotational contact with the inner wall of the mixing box. The mixing plates can rotate with the spiral blades, and can make the material at the bottom of the mixing box roll up and down, thereby improving the mixing efficiency and enabling it to be mixed more fully.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Two feeding barrels are arranged above the mixing box. The push rod of the feeding cylinder slides into the feeding barrel and is provided with a piston. Under the action of the feeding cylinder, the piston can add the material into the mixing box in a quantitative manner, and the piston can retract, which is also convenient for the subsequent addition of materials. The one-way valve is provided to prevent the material from penetrating.

[0016] 2. By setting a storage barrel above the feeding barrel, and coordinating the feeding cylinder and piston, the material inside the feeding barrel can be replenished in time, and the solenoid valve can ensure that there will be no deviation during normal feeding and the pass rate accuracy.

[0017] 3. By arranging spiral blades and mixing plates on the rotating shaft inside the mixing box, the spiral blades can move and mix two different materials, and the mixing plates can make the two materials roll up and down, thereby making them more fully mixed. BRIEF DESCRIPTION OF THE DRAWINGS
