Description

TECHNICAL FIELD

[0001] The utility model belongs to rubber closed mill batching technical field especially relates to a rubber closed mill batching device. BACKGROUND

[0002] Rubber is a kind of material widely used in industry, such as automobile tire, cable insulation cover, shoes, etc. Since the application of rubber in industry is very wide, the demand for rubber in industry is very large.

[0003] In the rubber production process, the raw rubber material needs to be closed-mixed, which can effectively increase the ductility of rubber molecules and greatly improve the performance of rubber materials.

[0004] In the rubber mixing process, various auxiliary materials need to be added to the rubber being mixed to improve the performance of the rubber. During the feeding process, the various auxiliary materials need to be thoroughly mixed before being fed into the closed-mixing equipment. Currently, batching machines are used for batching in the production process. After batching, different materials are fed into the batching hopper through different feeders, which has the following defects: after the batching hopper is discharged, the materials cannot be mixed. Although the batching amount of auxiliary materials is not high, the quality of the rubber material produced is uneven due to the lack of thorough mixing of the materials before being fed into the closed-mixer.

[0005] Therefore, during the actual discharging process into the closed-mixer, the operator needs to mix the batched materials. The current method is to pour the materials out of the batching hopper after batching and mix them in a small mixer. This method can indeed achieve the mixing effect, but first, the materials need to be poured out of the batching hopper, and second, the materials need to be mixed in the mixer. After the above two operations, the loss of materials is large, the accuracy of batching is reduced, and especially for materials with a small amount of components, the quality of the rubber obtained after subsequent processing is also uneven.

[0006] Moreover, the above method also leads to a complicated processing procedure. Therefore, the current method has obvious disadvantages in the batching process. INVENTION CONTENTS

[0045] Embodiment 1

[0046] As shown in Figures 1-5 A rubber mixing and batching device, comprising a batching hopper, a plurality of batching mechanisms are installed on the batching hopper. Through the batching mechanism, the auxiliary components for producing rubber are separately fed in the rubber processing process, and then the subsequent mixing and batching are completed, and finally directly into the internal mixer for production.

[0047] Specifically, the batching mechanism comprises a screw conveyor, wherein the screw conveyor is a conventional screw feeder disclosed in the prior art, and the main structure comprises a barrel 11 and a feeding auger installed in the barrel 11 and a feeding motor 12 driving the feeding auger. At the same time, the screw conveyor is provided with a feeding hopper 13; the material is fed through the feeding hopper 13 and then falls into the barrel 11 for pushing.

[0048] The above-mentioned screw conveyor is installed on the batching hopper through a mounting bracket structure.

[0049] Specifically, in order to realize the stable installation of the screw conveyor, the above-mentioned mounting bracket structure comprises a mounting bracket 14, a plurality of support seats 141 are fixedly connected to the top of the mounting bracket 14, and the support seat 141 supports the barrel 11 of the screw conveyor (specifically, a support hole for limiting the support of the barrel 11 is formed on the support seat). At the same time, the feeding motor 12 is also fixedly installed through the motor fixing seat fixed on the mounting bracket 14.

[0050] The structure of the mounting bracket 14 is:

[0051] The mounting bracket 14 comprises a V-shaped bracket portion (the upper end of the V-shaped bracket portion is a horizontally arranged bracket body portion, and the lower end is an inclined inclined bracket portion 142), the inner ends of the V-shaped bracket portion are welded with a connecting bracket portion (the bracket body portion and the inclined bracket portion 142 are welded on the connecting bracket portion), and the connecting bracket portion is tightly fastened on the outer side wall of the batching barrel 11 through a plurality of bolts.

[0052] The above-mentioned way realizes the stable and fixed installation of the screw conveyor on the batching hopper, and the discharge end of the barrel 11 faces the inside of the batching hopper.

[0053] After being conveyed by the aforementioned independent screw conveyor, the auxiliary materials enter the batching hopper for mixing.

[0054] The aforementioned batching hopper has the following shape: it includes a cylindrical hopper section 21 and a conical hopper section 22 integrally formed at the bottom of the cylindrical hopper section 21. In conventional methods, a mounting flange is installed at the bottom of the conical hopper section 22. The mounting flange is connected to a discharge pipe (not shown in the figure), and then installed onto the feed inlet of the internal mixer via the discharge pipe. The entire device is elevated above the internal mixer and installed on a work stand in the workshop. This integrates batching, mixing, discharging, and feeding, significantly improving the feeding efficiency during the internal mixing process.

[0055] Example 2

[0056] like Figures 1-5 As shown, this embodiment, based on the structure of embodiment 1, aims to fully mix the materials that independently enter the batching hopper, while maintaining a stable feeding method (materials are fed vertically without scattering) during the mixing process. A mixing hopper 3 (located inside the cylindrical hopper section 21) is installed inside the batching hopper. The mixing hopper 3 includes a cylindrical hopper section and a conical hopper section 31 integrally formed from the cylindrical hopper section. Several mixing plates 4 are fixedly connected to the conical hopper section 31 (the mixing plates 4 are vertically welded to the conical hopper section 31; because the conical hopper section 31 is inclined, the mixing plates 4 are inclined and are welded and fixed to the conical hopper section 31 using stainless steel plates).

[0057] When the screw conveyor delivers the material into the batching hopper, the material actually enters the mixing hopper 3. The rotating mixing hopper 3 agitates and mixes the material. Specifically, the material is fed into the mixing hopper 3, and the rotating mixing hopper 3, under the action of the mixing plate 4, agitates and disperses the material.

[0058] The advantages of this method are as follows: By agitating the material through the rotating mixing hopper 3, the material is less likely to be stirred out of the hopper during the agitation process, thus preventing material spillage. Secondly, the rotating method ensures that the material is continuously discharged from the screw conveyor, even though the discharge position of the screw conveyor is fixed. This further promotes the mixing of materials. As different materials are discharged into the mixing hopper 3, the rotation of the mixing hopper 3 causes repeated mixing between different materials, greatly improving the degree of mixing.

[0059] Traditional mixing methods, where the material is fed to a fixed point, not only prevent the materials from mixing spontaneously, but also make it easy for the materials to escape from the hopper structure due to the impact of the mixing structure during the mixing process.

[0060] Example 3

[0061] like Figures 1-5As shown, the embodiment is based on the structure of embodiment 2, in the working process, in order to realize the stable rotation of the mixing hopper 3, realize the continuous change of the falling point position of the material, increase the mixing degree, the above-mentioned cylindrical hopper part is rotated and rolled on the inner side wall of the feeding hopper through the roller structure.

[0062] Specifically, the roller structure includes a plurality of circumferentially distributed small rollers 6, and correspondingly, the inner side wall of the feeding hopper is provided with a corresponding annular inner groove A, and specifically, the small rollers 6 are limited to roll in the annular inner groove A (the annular inner groove A is provided on the inner side wall of the cylindrical hopper part 21). At the same time, the small rollers 6 are rotatably connected with a rotating shaft, the rotating shaft penetrates from the position of the annular inner groove A, and the rotating shaft is fixedly connected to the outer side wall of the cylindrical hopper part.

[0063] At the same time, in order to improve the rolling stability of the small rollers 6 in the rotating process, according to the existing roller limiting rolling mode, the top and bottom parts of the above-mentioned annular inner groove A are provided with annular grooves for limiting the rolling of the small rollers 6 (not shown in the figure); the upper end and the lower end of the small roller 6 are limited to roll in the annular groove.

[0064] The above-mentioned mixing hopper 3 is driven to rotate by a motor structure. Specifically, the top of the cylindrical hopper part is fixedly connected with an annular flange 32 which is protrudingly arranged towards the inner side of the barrel mouth; the motor structure includes a connecting frame 52 (in the form of a U-shaped structure) fixedly connected to the top position of the annular flange 32, and the motor structure further includes a driving motor 5, the output shaft of the driving motor 5 is fixedly installed at the top center position of the connecting frame 52; a motor fixed support is installed on the driving motor 5, and the motor fixed support is installed on the top of the feeding hopper.

[0065] The above-mentioned motor fixed support includes a support seat, the bottom center position of the support seat is fixedly installed on the driving motor 5 through a connecting screw; the two ends of the support seat are provided with mounting screws 51, and the mounting screws 51 are fixedly installed on the feeding hopper.

[0066] In the working process, under the driving of the driving motor, at this time, the mixing hopper 3 rotates, and in the rotating process, due to the effect of the plurality of circumferentially distributed small rollers 6 installed on the outer side wall of the mixing hopper 3, the mixing hopper 3 is limited to rotate in the feeding hopper, and the rolling stability of the roller rotating mode is high, and the flexibility is high, which greatly improves the effect of self-rotating mixing of the mixing hopper 3.

[0067] Embodiment 4

[0068] As Figures 1-5As shown, in the actual working process, in order to improve the accuracy of the ingredients, realize the metering in the batching process, the feeding hopper 13 of the above-mentioned screw conveyor is designed into a conventional metering hopper disclosed in the prior art according to the existing mode. During the conveying process of the material in the screw conveyor, the feeding hopper 13 can meter the feeding amount.

[0069] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
