Description

Technical Field

[0001] This utility model relates to the field of silicone production technology, and specifically discloses an anti-blocking discharge device for silicone production. Background Technology

[0002] Silicone production is a fine chemical process that integrates multiple stages such as raw material preparation, material handling, and curing. The basic raw material of silicone is mainly siloxane (such as dimethylcyclosiloxane), which is the core of silicone molecular chain. It needs to be combined with reinforcing agents (often silica, to improve silicone strength) and crosslinking agents (such as peroxides, to help subsequent curing). Additives (such as pigments, flame retardants, anti-aging agents, etc., to adjust color or performance) can also be added as needed.

[0003] Currently available silicone production discharge devices generally suffer from the problem of easy clogging of the discharge hopper. On the one hand, when material accumulates in the discharge hopper, it easily forms a stable "arch bridge" structure, hindering the material from falling. On the other hand, if the temperature of the inner wall of the discharge hopper cannot be maintained, silicone easily adheres to the hopper wall, further aggravating the clogging. After clogging occurs, the machine must be stopped for manual cleaning, which not only reduces production efficiency but also increases labor intensity. Therefore, an anti-clogging discharge device for silicone production is needed to solve this problem. Utility Model Content

[0004] This utility model proposes an anti-blocking discharge device for silicone production. The anti-blocking mechanism can continuously disturb the material, break up the "arch bridge" structure and tear apart the clumps to prevent blockage. The heating cavity reduces the risk of blockage and also prevents waste caused by material adhering to the silo wall.

[0005] This utility model is implemented as follows: a silicone production anti-blocking discharge device includes a device body, a stirring mechanism is provided inside the device body, a discharge hopper is connected to the bottom end of the device body, and an anti-blocking mechanism is provided inside the discharge hopper.

[0006] The anti-blocking mechanism includes a rotating ring rotatably connected to the bottom of the discharge bin, an arch-breaking rod fixedly connected to the inner wall of the rotating ring, multiple levers fixedly connected to the outer wall of the arch-breaking rod, a large gear fixedly connected to the outer wall of the rotating ring, a small gear meshing with the large gear, and a drive motor whose output end is fixedly connected to the small gear.

[0010] In a preferred embodiment of the anti-blocking discharge device for silicone production according to this utility model, the end of the lever away from the arch-breaking rod is tapered.

[0011] As a preferred embodiment of the anti-blocking discharge device for silicone production according to this utility model, the top of the device body is provided with a feed inlet, and the top of the feed inlet is threadedly connected with a sealing cap.

[0014] The beneficial effects of this utility model are:

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-3 A silicone production anti-blocking discharge device includes a device body 1, a stirring mechanism is provided inside the device body 1, a discharge chamber 2 is connected to the bottom end of the device body 1, and an anti-blocking mechanism is provided inside the discharge chamber 2.

[0024] The anti-blocking mechanism includes a rotating ring 201 rotatably connected to the bottom of the discharge bin 2, an arch-breaking rod 205 fixedly connected to the inner wall of the rotating ring 201, multiple levers 206 fixedly connected to the outer wall of the arch-breaking rod 205, a large gear 202 fixedly connected to the outer wall of the rotating ring 201, a small gear 203 meshing with the large gear 202, and a drive motor 204 whose output end is fixedly connected to the small gear 203.

[0025] The outer wall of the discharge hopper 2 is provided with a heating cavity 3, and the interior of the heating cavity 3 is provided with an electric heating wire 301.

[0026] In this embodiment: the drive motor 204 drives the small gear 203 to rotate, which in turn drives the large gear 202 and the rotating ring 201 to rotate, causing the arch-breaking rod 205 and the lever 206 to rotate accordingly, continuously agitating the silicone material in the discharge bin 2, effectively breaking the "arch bridge" structure formed by the accumulation of material and tearing the clumps, ensuring smooth material flow and preventing blockage.

[0027] Heating cavity 3 is heated by heating wire 301 to maintain the temperature of the discharge chamber 2 wall, preventing silicone from sticking or clumping due to cooling, and further ensuring smooth discharge.

[0028] As a technical optimization of this utility model, the stirring mechanism includes a stirring component 101 disposed inside the device body 1, and a servo motor 102 installed on the top of the device body 1, with its output end fixedly connected to the stirring component 101.

[0029] In this embodiment, the servo motor 102 drives the stirring component 101 to uniformly stir the silicone in the device body, so that the silicone material is fully mixed in the device body 1.

[0030] As a technical optimization of this utility model, the discharge bin 2 has a conical structure, and the shape of the arch-breaking rod 205 is adapted to the inner wall of the discharge bin 2.

[0031] In this embodiment: the cone-shaped discharge bin 2 is adapted to the shape of the arch-breaking rod 205, reducing dead angles, enhancing the coverage of the material by the arch-breaking rod 205, and improving the anti-blocking efficiency.

[0032] As a technical optimization of this utility model, the end of the lever 206 away from the arch-breaking lever 205 is tapered.

[0033] In this embodiment: the tapered end reduces rotational resistance, enhances the penetration of materials, and easily inserts into the silicone accumulation area. During rotation, it effectively tears apart material clumps and avoids blockage.

[0034] As a technical optimization of this utility model, the top of the device body 1 is provided with a feed inlet 103, and the top of the feed inlet 103 is threaded with a sealing cap.

[0035] In this embodiment: by opening the sealing cover, material can be added into the device body 1 through the feed port 103.

[0036] As a technical optimization of this utility model, a support frame is fixedly connected to the outer wall of the device body 1, and a support plate for supporting the drive motor 204 is fixedly connected to the inner wall of the support frame.

[0037] In this embodiment: the entire device can be supported by the support frame, and the drive motor 204 can be supported by the support plate.

[0038] As a technical optimization of this utility model, a controller is installed on the outer wall of the device body 1, and the servo motor 102, the drive motor 204 and the heating wire 301 are all electrically connected to the controller.

[0039] In this embodiment, the servo motor 102 and drive motor 204 can be controlled to work normally by the controller.

[0040] The working principle and usage process of this utility model are as follows: Open the sealing cover of the feed port 103 at the top of the device body 1, add the silicone material to be processed into the device body 1 through the feed port 103, then start the controller, the controller controls the servo motor 102 to start working, the output end of the servo motor 102 drives the stirring component 101 to rotate in the device body 1, and uniformly stir the silicone material to ensure that the material is fully mixed, laying the foundation for the subsequent discharge process.

[0041] The stirred material enters the cone-shaped discharge hopper 2 under the action of gravity. At this time, the controller starts the drive motor 204. The output end of the drive motor 204 drives the small gear 203 to rotate, which drives the large gear 202 to rotate synchronously. This, in turn, drives the rotating ring 201 to rotate at the bottom of the discharge hopper 2. The arch-breaking rod 205 rotates together with the rotating ring 201. Since the shape of the arch-breaking rod 205 is adapted to the inner wall of the discharge hopper 2, it can fully cover the internal space of the discharge hopper 2 during rotation, continuously disturbing the silica gel material, effectively breaking the "arch bridge" structure formed by the accumulation of material, and preventing the material from clogging the discharge hopper.

[0042] During the material discharge process, the controller synchronously controls the operation of the heating wire 301 in the heating cavity 3. The heating wire 301 heats the heating cavity 3, and the heat is transferred to the wall of the discharge bin 2 to maintain the temperature of the discharge bin 2 wall, preventing the silicone from sticking to the bin wall or clumping due to cooling, and further ensuring the smooth flow of materials.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
