Description

TECHNICAL FIELD

[0001] The utility model belongs to rubber mixing technical field, especially a rubber mixing high melting point material hot melting unloading device. BACKGROUND

[0002] The processing of rubber mainly includes mixing and mixing, which is different from the open mixing in the open air, and the mixing is to process the rubber material in a sealed device. The mixing of rubber can improve the performance of rubber, such as increasing the deformation performance of rubber.

[0003] During the mixing of rubber, materials such as resin are often added to the rolled rubber. During the mixing process, the roller temperature of the rolled rubber is about 60 degrees Celsius, and the added auxiliary materials often contain some high melting point materials such as resin materials. In the actual process, the resin is directly added to the mixed rubber, and it is difficult to mix the rubber by relying on the rolling action due to the difficulty of high temperature melting of the resin, which leads to uneven performance of the produced rubber, which is caused by uneven distribution of high melting point materials such as resin on the rubber.

[0004] Therefore, in the actual production process, the material, especially the high melting point material, needs to be heated, and the hopper of the current equipment is difficult to heat the material to a high temperature.

[0005] In the actual work process, the high melting point material is preheated by putting the material into a container with a stirring device, and the container is heated on a heat source. However, it is found that during the operation process, due to the easy cooling and solidification of the material, the part close to the heat source is melted (the bottom layer of the material), and the part far away from the heat source is cooled and solidified (the upper layer of the material), so that the heating effect is not obvious, and the stirring resistance is very large. And after the resin and other materials are hot melted, the consistency of the material is relatively large, which further leads to large stirring resistance. At the same time, due to the large consistency of the material, when it is transferred from the container to the equipment, the material is cooled and the consistency is further increased, which makes the unloading process more difficult.

[0043] Embodiment 1

[0044] As shown in Figures 1-5 A rubber mixing high melting point material hot melting blanking device, including hopper 1, the shape of hopper 1 is as follows: hopper 1 includes cylindrical portion, and the short conical portion of one-piece forming in the bottom position of cylindrical portion.

[0045] In order to realize the control of discharging, according to the existing mode, the bottom of the short conical part is provided with a discharging port, the discharging port is communicated with a discharging pipe (not shown in the figure), and a valve is installed on the discharging pipe. In the working process, the valve is opened to add the material melted by liquid into the working equipment (Banbury mixer).

[0046] The above structure realizes the heating of the high-melting-point material during the feeding process by improving the hopper 1, and the material is directly discharged after being heated and melted.

[0047] Specifically, the hopper 1 is fixedly connected with a heating inner cylinder 41 (the heating inner cylinder 41 is fixedly installed in the cylindrical part), and the outer side wall of the heating inner cylinder 41 is arranged in a spaced manner with the inner side wall of the hopper 1.

[0048] Specifically, the upper end cylinder port of the heating inner cylinder 41 is fixedly connected with an upper annular flange 411 between the hopper 1. Meanwhile, the lower end cylinder port of the heating inner cylinder 41 is fixedly connected with a lower annular flange 412, and the lower annular flange 412 is fixedly connected to the lower end part of the side wall of the hopper 1.

[0049] In this way, the heating inner cylinder 41 is arranged in a spaced manner with the inner side wall of the hopper 1. Meanwhile, the outer side wall of the heating inner cylinder 41 is fixedly installed with a heating resistance structure 43.

[0050] Specifically, according to the existing mode, the heating resistance structure 43 is a conventional heating resistance disclosed in the prior art, which is in a spiral shape (long cylinder spiral structure) and is designed to ensure that the heating inner cylinder 41 is uniformly heated.

[0051] According to the existing mode, the wire electrically connected to the heating resistance structure 43 penetrates the hopper 1 and is electrically connected to the heating resistance structure 43.

[0052] In the working process, the heating inner cylinder 41 is heated under the heating of the heating resistance structure 43. The above-mentioned mode effectively solves the problem that the high-melting-point material is not uniformly distributed on the rubber in the Banbury mixer due to the inability to melt, which further affects the quality of the rubber product.

[0053] In order to improve the uniformity of the heating of the high-melting-point material such as resin during the heating process, that is, to avoid overheating of the material near the side wall of the heating inner cylinder 41, the temperature of the material near the side wall of the heating inner cylinder 41 is not enough, the rubber Banbury high-melting-point material hot-melt discharging device also includes a stirring mechanism 3 for stirring the hot-melt material.

[0054] By improving the stirring mechanism 3, the material in the heating inner cylinder 41 is fully stirred and uniformly dispersed, and the consistency of the material increases after being heated, and the stirring resistance increases. The stirring mode and structure are improved, and the specific improvements are as follows:

[0055] The stirring mechanism 3 includes an annular rotating seat 31, and several rollers 32 are installed at the bottom of the annular rotating seat 31. The rollers 32 roll on the upper annular flange 411. Several stirring structures for stirring the hot melt material in the heating inner cylinder 41 are installed on the inner side wall of the annular rotating seat 31.

[0056] This method achieves the goal of reducing the resistance to rotational mixing during the mixing process because the annular rotating seat 31 rotates via the rolling rollers 32. Simultaneously, the mixing mechanism 3 also includes four drive wheel structures 2 (distributed in a circumferential array) that drive the annular rotating seat 31 to rotate, with the drive wheels rolling against the outer wall of the hopper 1.

[0057] Example 2

[0058] like Figures 1-5 As shown, based on the structure of Embodiment 1, the agitation structure includes a fixed arm 33 fixedly connected to the annular rotating seat 31; an adjustable arm 341 with an adjustable position is installed on the fixed arm 33, and a stirring plate 34 (the stirring plate 34 has a triangular cross-sectional shape and is made of stainless steel) is detachably installed on the adjustable arm 341. Specifically, the adjustable arm 341 is L-shaped; the lower end of the adjustable arm 341 has an installation port for installing the stirring plate 34, and the lower end of the adjustable arm 341 is threaded with a bolt for fastening the stirring plate 34.

[0059] The above method enables the replacement of the deformed stirring plate 34 during operation and facilitates the subsequent cleaning of the solidified resin adhering to the plate.

[0060] An adjusting rod 3411 is fixedly connected to the upper end of the adjusting arm 341. The adjusting rod 3411 is slidably connected to the fixed arm 33, and several bolts 331 for locking the adjusting rod are threaded onto the fixed arm 33. This method allows for adjustment of the stirring plate 34. For example, adjusting the stirring plate 34 closer to the side wall of the heating inner cylinder 41 increases the agitation of the raw materials near the side wall of the heating inner cylinder 41. In cases of excessively high temperatures, to prevent overheating, it increases the agitation force on the material near the side wall of the heating inner cylinder 41, ensuring uniform heat distribution.

[0061] Specifically, a sliding cavity is provided on the fixed arm 33 to connect the adjusting rod 3411. The bolt 331 passes through the sliding cavity and presses against the adjusting rod 3411. Adjustment is achieved by loosening the bolt 331.

[0062] This method also allows for adjustment of the angle of the stirring plate 34, making it easier to increase the stirring effect.

[0063] At high temperatures, the hot-melted material has a high viscosity. Under the action of the above structure, the high-viscosity high-temperature material and the incompletely melted material are fully mixed. The mixing process is highly flexible, and the stirring position can be adjusted according to the material temperature. This avoids overheating of the material and disperses the high-temperature material to the low-temperature incompletely melted material, thereby accelerating the melting effect and regulating the uniform distribution of the material temperature.

[0064] Example 3

[0065] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, in order to drive the entire device, the aforementioned drive wheel structure 2 includes a pressing roller 22 that rolls against the outer wall of the hopper 1; the pressing roller 22 is rotatably connected to a roller bracket 221, and a motor 21 for driving the pressing roller 22 is mounted on the roller bracket 221. Specifically, in the conventional manner, the output shaft of the motor 21 is mounted on the pressing roller 22, and the output shaft is rotatably connected to the roller bracket 221.

[0066] Meanwhile, a connecting bracket 23 is installed on the top of the roller bracket 221, and the inner end of the connecting bracket 23 is fixedly installed on the top position of the annular rotator 31; the motor 21 is fixedly installed on the connecting bracket 23, specifically, the motor is fastened to the connecting bracket 23 by means of a connecting rod.

[0067] During operation, driven by motor 21, all the clamping rollers 22 roll against the outer wall of hopper 1 in the same direction. With the cooperation of the four clamping rollers 22, and relying on the friction between them and the outer wall of hopper 1, and supported by the rollers 32 rolling on the upper annular flange 411, the entire device is driven to rotate and stir. This rotational stability is higher than that of traditional mechanical stirring structures. This is because materials with high viscosity may not melt evenly during heating, and uneven force on the stirring structure, such as the stirring paddle, can easily lead to reduced stability of the stirring structure. The aforementioned circumferential drive rotation method offers high stability and can quickly break up materials with uneven melting (in the initial stage of melting), improving the melting process.

[0068] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
