Description

Technical Field

[0001] The utility model relates to the field of silica gel production, in particular to an automatic quantitative feeding device for silica gel production. Background Technique

[0002] In the process of silica gel production, in addition to basic silica gel raw materials, a variety of auxiliary materials need to be added to ensure the quality and performance of the product. These auxiliary materials include fillers, which are used to improve the mechanical strength and other physical properties of silica gel products, such as talcum powder, white carbon black, etc.; crosslinking agents, which are used to improve the physical properties and stability of silica gel, and commonly used ones include silanes, titanate esters, etc.; catalysts, stabilizers, colorants, vulcanizing agents, masterbatch, luminous powder, fluorescent powder, phosphor. In addition, other auxiliary materials, such as mold release agents, diluents, etc., may also be used in the production process to optimize the production process and improve the product quality.

[0003] After retrieval, the Chinese patent publication number: CN216889150U discloses a feeding device for silica gel production. Through the bottom plate and universal wheels, combined with an electric telescopic rod, the feeding box can be conveniently moved and the height can be adjusted, so as to conveniently feed the materials. Through the feeding box and the reduction motor, combined with the rotating column and the spiral blade, the materials can be conveniently pushed, so that the materials will not solidify together and are convenient for discharging, and there is no need for workers to manually scrape them out.

[0004] In the above technical solution, the feeding box and the reduction motor are used to push the materials, so that the added materials will not solidify together.

At the same time, the lack of quantitative feeding during feeding will lead to the overuse of raw materials. Therefore, an automatic quantitative feeding device for silica gel production is proposed to solve the above problems. Content of the Utility Model

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: An automatic quantitative feeding device for silicone production, including a fixed barrel 1. Four support legs are arranged at equal intervals at the bottom of the fixed barrel 1, which is convenient for placing the fixed barrel 1 on the mixing barrel for silicone production for feeding. A feeding pipe 2 is fixedly connected to the bottom of the fixed barrel 1. A quantitative structure is arranged inside the fixed barrel 1. The quantitative structure includes a material holding cylinder 3. Sieve holes 4 are formed on the surface of the material holding cylinder 3. A fixed block 5 is fixedly connected to the inner wall of the material holding cylinder 3. A sieve plate 6 is arranged on the top of the fixed block 5. The aperture of the sieve plate 6 is larger than the aperture of the sieve holes 4. A quantitative component is arranged at the bottom of the material holding cylinder 3. A feeding component is arranged inside the fixed barrel 1. A driving component is arranged inside the fixed barrel 1.

[0037] Refer to Figures 3 - 5, the outer surface of the sieve plate 6 is adapted to the inner wall of the material storage cylinder 3. The quantitative component includes a receiving tray 7. The top end of the feeding pipe 2 penetrates into the interior of the receiving tray 7. One end of the feeding pipe 2 close to the receiving tray 7 is telescopically arranged. A discharge pipe 8 is fixedly connected to the bottom of the receiving tray 7. An electromagnetic valve 9 is arranged on the surface of the discharge pipe 8. The electromagnetic valve 9 controls the discharge of the discharge pipe 8 into the interior of the receiving tray 7. The feeding component includes a telescopic rod 10. The bottom end of the telescopic rod 10 is fixedly connected to the inner wall of the fixed barrel 1. A spring 11 is sleeved on the outer wall of the telescopic rod 10. The bottom end of the spring 11 is fixedly connected to the inner wall of the fixed barrel 1. There are three groups of the telescopic rod 10 and the spring 11, and the three groups of the telescopic rod 10 and the spring 11 are circumferentially arranged in an array with the central axis of the fixed barrel 1 as the axis of symmetry, providing a triangular positioning support function for the receiving tray 7. The top end of the spring 11 is fixedly connected to the lower surface of the receiving tray 7. A pressure switch 12 is fixedly connected to the inner wall of the fixed barrel 1. When the switch end of the pressure switch 12 is stressed, the electromagnetic valve 9 closes. When the switch end of the pressure switch 12 loses the external extrusion force, the electromagnetic valve 9 opens. The driving component includes an inclined plate 13. The bottom of the inclined plate 13 is fixedly connected to the inner surface of the receiving tray 7. One end of the inclined plate 13 close to the feeding pipe 2 is lower than the end of the inclined plate 13 far from the feeding pipe 2. The inclined plate 13 can accelerate the flow of the material in the receiving tray 7 to the feeding pipe 2 under the influence of gravity. An installation plate 14 is fixedly connected to the outer wall of the material storage cylinder 3. A vibration motor 15 is fixedly connected to the outer wall of the installation plate 14. The vibration motor 15 can drive the material storage cylinder 3 to vibrate, accelerating the screening of the material inside the material storage cylinder 3.

[0038] Refer to Figure 2 , Figures 4 - 5 , a fixing ring 16 is fixedly connected to the inner wall of the fixed barrel 1. A double telescopic barrel 17 is fixedly connected to the inner surface of the fixing ring 16. There are several groups of the double telescopic barrels 17, and the several groups of the double telescopic barrels 17 are circumferentially arranged in an array with the central axis of the fixing ring 16 as the axis of symmetry. One end of the double telescopic barrel 17 far from the fixing ring 16 is fixedly connected to the outer surface of the material storage cylinder 3. A damper 18 is fixedly connected to the outer surface of the material storage cylinder 3. There are three groups of the dampers 18, and the three groups of the dampers 18 are distributed in a triangle with the central axis of the fixing ring 16 as the axis of symmetry.

[0039] Working principle: The raw materials to be added are placed inside the material storage cylinder 3. The raw materials are sieved at multiple levels through the cooperation of the sieve plate 6 and the sieve holes 4. The vibration motor 15 drives the material storage cylinder 3 to vibrate. After the vibration motor 15 is turned on, since the damper 18 and the bidirectional telescopic barrel 17 can reduce the impact of the vibration force on the fixed barrel 1, the material storage cylinder 3 is accelerated for sieving to improve the sieving efficiency. In the initial state, the solenoid valve 9 is in the open state. When the raw materials are sieved, they will fall into the inside of the receiving tray 7. When the receiving tray 7 is filled with raw materials, its weight will gradually increase. The receiving tray 7 presses on the telescopic rod 10 and the spring 11, and the two will be compressed after being stressed until the receiving tray 7 touches the pressure switch 12. After the pressure switch 12 is stressed, the solenoid valve 9 closes, and the raw materials will stop discharging from the discharge pipe 8. The raw materials inside the receiving tray 7 will quickly flow to the blanking pipe 2 through the inclined plate 13 for quantitative feeding. When the raw materials inside the receiving tray 7 are gradually discharged, the weight of the receiving tray 7 decreases, and the telescopic rod 10 and the spring 11 will gradually rebound, driving the receiving tray 7 away from the pressure switch 12, and quantitative feeding is carried out in a cycle.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
