Description

Technical Field

[0001] This utility model relates to the field of organosilicon resin production technology, and specifically to a mixing device for organosilicon resin production. Background Technology

[0002] Silicone resin coatings are widely used in modern waterproofing, insulation, corrosion protection and other fields. By covering the surface of external products with a silicone resin coating, the overall properties can be improved. Silicone resin coatings require multiple processing steps in the production process, including a mixing process, in which various ingredients are thoroughly mixed using a mixing device.

[0003] A search revealed existing technology (publication number: CN222034413U, which describes "a quantitative proportioning silicone resin coating mixing device, relating to the field of silicone resin coating mixing technology, aiming to solve the shortcomings of existing mixing devices in quantitative proportioning and thorough mixing, and the need to improve overall processing efficiency). The key technical points include a mixing box, a feeding seat fixedly connected to the upper surface of the mixing box, a measuring hopper rotatably installed inside the feeding seat, a measuring cavity provided on the outer surface of the measuring hopper, a screw fixedly connected to the bottom surface of the measuring cavity, an adjusting plate sleeved on the outside of the screw, an adjusting knob rotatably installed on the outer surface of the adjusting plate, the adjusting knob being threaded to the outside of the screw, and a second motor fixedly installed on the side surface of the feeding seat. This achieves the effect of quantitative proportioning and thorough mixing, resulting in high processing efficiency."

[0004] Although existing mixing devices for silicone resin production achieve quantitative feeding and thorough mixing, they still have some shortcomings: existing mixing devices for silicone resin production can only be used for feeding one type of raw material at a time, while silicone grease production requires multiple raw materials, thus requiring multiple continuous feedings, resulting in low efficiency. Secondly, silicone resin coatings generate bubbles during processing and mixing, and the aforementioned mixing devices cannot eliminate these bubbles, affecting product quality. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, a mixing device for the production of organosilicon resin is provided to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a mixing device for producing organosilicon resin is provided, comprising: an organosilicon resin production mixing tank, wherein a vacuum pump and a stirring motor are provided on the upper side of the mixing tank, and a stirring shaft is connected to the lower end of the stirring motor; an auxiliary material dispensing component is connected to the outer side of the mixing tank, the auxiliary material dispensing component includes a storage hopper, and a discharge pipe is connected to the lower end of the storage hopper; a filling pipe is connected to the lower end of the mixing tank, and a storage tank is connected to the lower end of the filling pipe; a lead screw is provided inside the storage tank, and a screw block is connected to the outer side of the lead screw, and a piston block is connected to one side of the screw block.

[0007] Furthermore, the suction end of the vacuum pump is connected to the inside of the silicone resin production mixing tank via a pipe, and the discharge end of the vacuum pump is located outside the silicone resin production mixing tank.

[0008] Furthermore, the feed pipe is equipped with a first electric valve, and a first electronic flow meter is provided on the lower side of the first electric valve.

[0009] Furthermore, the injection pipe is equipped with a second electric valve and a second electronic flow meter, and the lower end of the injection pipe is connected to the inlet at the upper end of the storage box.

[0010] Furthermore, the lower end of the silicone resin production mixing box is connected to a first leg, and the lower end of the storage box is connected to a second leg.

[0011] Furthermore, a discharge pipe is connected to the upper side of the storage box, and a solenoid valve is installed inside the discharge pipe.

[0012] Furthermore, one end of the lead screw is connected to a stepper motor, and the screw block and piston block on the outside of the lead screw are slidably connected to the inner wall of the storage box.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By utilizing multiple auxiliary material feeding components, multiple auxiliary materials and main materials (organosilicone) can be simultaneously fed into the mixing tank for the production of organosilicon resin. Each material is quantitatively fed through a first electric valve and a first electronic flow meter, thereby improving the material feeding efficiency. Then, by starting the stirring motor, the stirring shaft is driven to mix and stir the multiple materials. At the same time, the vacuum pump is started to evacuate the inside of the mixing tank for the production of organosilicon resin, thereby achieving the effect of vacuum degassing while stirring, thus ensuring the quality of the mixed materials.

[0015] 2. The storage bin facilitates the downward flow of the mixed raw materials, enabling temporary storage. During use, the stepper motor can be started to rotate the drive screw, which in turn moves the screw plate and the piston block. The piston block then squeezes the raw materials on one side toward the discharge pipe, and with the solenoid valve open, the raw materials are discharged. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 4As shown, this utility model provides a mixing device for producing organosilicon resin, including: an organosilicon resin mixing tank 1, a vacuum pump 11 and a stirring motor 12 are provided on the upper side of the organosilicon resin mixing tank 1, and a stirring shaft 13 is connected to the lower end of the stirring motor 12. An auxiliary material feeding component 2 is connected to the outer side of the organosilicon resin mixing tank 1. The auxiliary material feeding component 2 includes a storage hopper 21, and a feeding pipe 22 is connected to the lower end of the storage hopper 21. A feeding pipe 16 is connected to the lower end of the organosilicon resin mixing tank 1, and a storage tank 3 is connected to the lower end of the feeding pipe 16. A lead screw 34 is provided inside the storage tank 3, and a screw block 36 is connected to the outer side of the lead screw 34. A piston block 35 is connected to one side of the screw block 36.

[0023] In this embodiment, the mixing tank 1, the auxiliary material feeding component 2, and the storage tank 3 constitute the main structure of the mixing device for producing silicone resin involved in this application.

[0024] Specifically, the bottom of the mixing tank 1 for producing organosilicon resin is equipped with a funnel structure to facilitate the downward flow of raw materials.

[0025] Specifically, the auxiliary material dispensing component 2 is located on the upper end and side wall of the mixing tank, and the auxiliary material dispensing component 2 located on the upper side of the mixing tank is used for quantitative dispensing of the main raw material (organosilicone), while the other auxiliary material dispensing components 2 are used for dispensing other auxiliary raw materials (thermal conductive raw materials).

[0026] Specifically, the storage box 3 and the injection pipe 16 are designed to be detachably connected. When the raw material is used for immediate processing, the storage box 3 can be disconnected and the material can be discharged directly through the injection pipe 16. When it is used for temporary storage, the storage box 3 and the injection pipe 16 can be connected.

[0027] It should be noted that the silicone raw materials involved in this application are in liquid form, and the mixed raw materials are in a viscous fluid state, while the final silicone resin is in a paste form.

[0028] like Figures 1 to 4In this system, the suction end of the vacuum pump 11 is connected to the inside of the silicone resin production mixing tank 1 through a pipe, and the outlet end of the vacuum pump 11 is located outside the silicone resin production mixing tank 1. The discharge pipe 22 is equipped with a first electric valve 23, and a first electronic flow meter 24 is located below the first electric valve 23. The injection pipe 16 is equipped with a second electric valve 17 and a second electronic flow meter 18, and the lower end of the injection pipe 16 is connected to the inlet 31 opened at the upper end of the storage tank 3. The lower end of the silicone resin production mixing tank 1 is connected to a first support leg 14, and the lower end of the storage tank 3 is connected to a second support leg 15. The upper side of the storage tank 3 is connected to an outlet pipe 32, and a solenoid valve 33 is located inside the outlet pipe 32. One end of the lead screw 34 is connected to a stepper motor 37, and the screw block 36 and piston block 35 on the outside of the lead screw 34 are slidably connected to the inner wall of the storage tank 3.

[0029] Specifically, the vacuum pump 11 is turned on during the mixing process after the raw materials are fed. At this time, the electric valves of the multiple auxiliary material feeding components 2 are all closed, so that the bubbles generated during the stirring process can be de-bubbled normally due to the internal vacuum environment.

[0030] Specifically, the second leg 15 is designed as a hydraulic rod structure to facilitate the lifting and lowering of the storage box 3, thereby facilitating its detachable connection with the injection pipe 16.

[0031] As a preferred implementation, by setting a stepper motor 37, a lead screw 34, a piston block 35, and a screw block 36, it is easy to completely squeeze out the raw materials inside the storage box 3 during material discharge, thereby reducing the waste caused by raw material residue.

[0032] In use, multiple auxiliary material dispensing components allow for the simultaneous addition of various auxiliary materials and the main material (organosilicone) into the silicone resin production mixing tank. Each material is quantitatively dispensed via a first electric valve and a first electronic flow meter, thereby improving material dispensing efficiency. The stirring motor is then activated to drive the stirring shaft, mixing the various materials. Simultaneously, a vacuum pump is activated to create a vacuum inside the silicone resin production mixing tank, achieving vacuum degassing during mixing and ensuring the quality of the mixed materials. A storage tank facilitates the downward flow of the mixed materials for temporary storage. During operation, a stepper motor is activated, causing the drive screw to rotate and move the screw plate, which in turn moves the piston block. The piston block compresses the material on one side towards the discharge pipe, and with the solenoid valve open, the material is discharged.

[0033] The mixing device for producing organosilicon resin of this invention can effectively solve the problems mentioned in the background technology. It realizes the simultaneous quantitative addition of multiple raw materials on the basis of existing mixing device technology for producing organosilicon resin, and has further mixing and degassing effects, thereby improving production efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
