Description

Technical Field

[0001] This utility model relates to a resin profile raw material batching and mixing device, belonging to the field of batching and mixing technology. Background Technology

[0002] In the production of resin profiles, it is necessary to mix various raw materials in a certain proportion. Existing batching and mixing equipment usually has the following shortcomings: the current fixed raw material input is done manually, which is labor-intensive and inaccurate. In addition, solid materials are all added at once, which is not conducive to subsequent mixing, resulting in uneven mixing and affecting the production of profiles. Utility Model Content

[0003] This invention provides a resin profile raw material batching and mixing device, which solves the problems existing in the background art.

[0004] This utility model relates to a resin profile raw material mixing device, including a frame, a mixing tank fixed on the frame, a stirring shaft inside the mixing tank, a stirrer connected to the stirring shaft, a liquid raw material inlet pipe at the top of the mixing tank, a drive mechanism fixed at the top of the stirring shaft extending out of the mixing tank, a premixing box at the top of the mixing tank, at least two discharge hoppers connected to the mixing tank at the bottom of the premixing box, a feed inlet at the center of the top of the premixing box, the top of the feed inlet being closed, at least two screw conveyors fixed on the outer wall of the feed inlet, the feed inlets of the screw conveyors being connected to a raw material bin, and a distribution cone plate fixedly connected at the top of the stirring shaft passing through the premixing box, with material feeding plates evenly fixed on the distribution cone plate.

[0005] As a preferred embodiment, the mixing tank is equipped with a heating jacket on the outside and a temperature sensor inside. The bottom of the heating jacket is equipped with a steam inlet pipe and the top of the heating jacket is equipped with a steam outlet pipe. The driving mechanism includes a driven pulley fixed on the stirring shaft. The driven pulley is connected to a driving pulley via a belt. The driving pulley is fixedly connected to a drive motor. The drive motor is fixed on the mixing tank and can heat the mixing tank to achieve heating, stirring and mixing.

[0006] The bottom of the mixing tank is fixed with a support ring plate. The bottom of the heating jacket is welded and fixed to the outer side of the bottom of the support ring plate. The inner side of the support ring plate is fixed with a support rib plate. The bottom of the mixing tank is provided with a discharge port. The outer side of the bottom of the discharge port is provided with a support flange. The inner side of the support rib plate is fixed to the top of the support flange, making the heating jacket more stable.

[0007] As a preferred embodiment, the heating jacket includes an upper jacket and a lower jacket. A support ring plate, fitted onto the outer wall of the mixing tank, is provided on the inner side of the connection between the upper and lower jackets. The top of the support ring plate has a conical guide groove, and the bottom of the guide groove has evenly distributed guide holes. An arc-shaped anti-detachment groove is provided on the outer wall of the support ring plate. The upper and lower jackets have conical welding end faces. The inner end of the welding end face of the upper jacket is below the top of the anti-detachment groove, and the inner end of the welding end face of the lower jacket is above the bottom of the anti-detachment groove. The support ring plate increases the stability of the connection between the upper and lower jackets and better prevents the weld layer from detaching. Furthermore, the guide groove and guide holes allow condensate inside the heating jacket to flow downwards.

[0008] As a preferred embodiment, the frame includes support columns positioned at the four corners of the mixing tank. Mounting columns are fixed to the top of the support columns via connecting flanges and bolts. A fixing plate is located on the inner side of the mounting columns. Support frames are welded to the four sides of the bottom of the fixing plates. The bottom of the support frames is welded to the top of the connecting flanges of the mounting columns. Positioning slots that mate with the mounting columns are located at the four corners of the fixing plate, and an installation hole for the mixing tank to pass through is located in the center of the fixing plate. The positioning slots allow for quick positioning and installation of the fixing plate, and also ensure a more secure weld.

[0009] As a preferred embodiment, a top plate is fixed to the top of the mounting column, and a reinforcing rib is fixed to the bottom of the top plate. The bottom of the reinforcing rib is welded and fixed to the fixed plate. Second reinforcing ribs are also welded and fixed to the upper and lower connecting flanges, respectively, and are welded and fixed to the supporting column and the mounting column. This makes the structure more stable.

[0010] As a preferred option, a fixed platform is fixed to the upper outer side of the mounting column, and a ladder is fixed on the fixed platform. A second ladder connecting to the bottom frame of the raw material silo is also fixed on the fixed platform for easy maintenance.

[0011] This utility model has the following beneficial effects:

[0012] Raw materials in the raw material silo are quantitatively conveyed via a screw conveyor, reducing labor intensity and improving conveying accuracy. Solid materials conveyed by the screw conveyor enter the premixing tank for premixing. The inclined structure of the conical disc causes the material to flow and disperse in multiple directions as it falls. This dispersion effect allows the two materials to initially mix during the fall, resulting in a more uniform distribution and preventing localized accumulation. This reduces the possibility of material buildup and blockage at the discharge hopper inlet. Because the conical disc's dispersion effect prevents material from concentrating near the discharge port and causing congestion, it maintains smooth material conveying and improves production efficiency.

[0022] Working principle: When the drive mechanism is started, it drives the stirring shaft 2 to rotate, which in turn drives the distribution cone 16 and the agitator to rotate. At this time, the screw conveyor 14 starts, quantitatively conveying the material in the raw material silo 1 into the feed inlet 17 of the premixing tank 15, and then falls onto the distribution cone 16. After being pushed by the material-pushing plate 3 and swung by the distribution cone 16, the material is dispersed in all directions and evenly falls into the mixing tank 6 through the discharge hopper 13. Liquid raw materials are added through the liquid raw material inlet pipe at the top of the mixing tank 6. In this way, the premixed solid and liquid materials can be stirred and mixed under the stirring of the agitator.

The connection end of the upper and lower jackets is then fitted onto the outer side of the support ring plate 19, and welding is performed at the welding end face. The weld layer enters the anti-detachment groove 22, further preventing detachment.

[0026] The frame includes support columns 9 located at the four corners of the mixing tank 6. Mounting columns 20 are fixed to the top of the support columns 9 via connecting flange edges 21 and bolts. A fixing plate 5 is located on the inner side of the mounting columns 20.
