Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber processing and material compounding technology, and in particular to a connecting device for compounding rubber with other materials. Background Technology
[0002] In the fields of rubber processing and material compounding, achieving efficient and high-quality compounding of rubber compounds with other materials has always been a key focus in the industry.
[0003] Traditional methods of compounding rubber with other materials have many drawbacks. For example, in the rubber melting process, many devices lack effective stirring methods, resulting in uneven heating of the rubber compound and difficulty in achieving an ideal melting state. This not only affects the flowability and viscosity of the rubber compound, leading to insufficient bonding strength when compounded with other materials in the future and making it difficult to guarantee product quality, but also may cause localized overheating, resulting in deterioration of the rubber compound's properties, waste products, and increased production costs.
[0004] In terms of preheating and drying, existing equipment often fails to preheat materials quickly and evenly, and to dry the compounded product effectively. Some equipment uses heating elements with poor thermal conductivity, resulting in slow and uneven heat transfer, leading to insufficient preheating of the materials and unsatisfactory bonding between the compound and the materials during spray coating. Furthermore, incomplete or uneven drying can cause problems such as deformation and delamination in the product during subsequent use.
[0005] Furthermore, traditional spraying equipment has a relatively limited function, making it difficult to flexibly adjust the spraying method according to different production needs. Most spraying equipment can only spray from a single direction, failing to achieve all-round and precise spraying of materials, resulting in uneven coverage of the compound on the material surface, affecting the overall performance and appearance quality of the product. Moreover, the equipment is inefficient in heat utilization, with a large amount of heat wasted during transmission and use, increasing both energy consumption and production costs.
[0006] As the market demands increasingly higher quality and performance from rubber composite products, it is urgent to develop a composite bonding device that can overcome the aforementioned defects, achieve efficient melting and uniform spraying of the compound, optimize heat transfer and utilization, and is easy to operate with high practicality and applicability.
[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0031] Reference Figure 1-5 A connecting device for completing the compounding of rubber with other materials includes a housing 1, a take-up roller 12, an unwind roller 11, a hot melt tank 2, a heating module 5, a liquid storage tank 41, and four hollow plates 4. The take-up roller 12 and the unwind roller 11 are respectively arranged on both sides of the housing 1. The hot melt tank 2 is fixedly installed on the top inner wall of the housing 1.

The two spraying pipes 32 are arranged parallel to each other, and multiple nozzles are fixedly installed on the side of the two spraying pipes 32 that are close to each other. The molten fully mixed rubber can be sprayed onto the material from the top and bottom sides. In order to be able to use either spraying pipe 32 for spraying as needed, so as to have good applicability, control valves 33 are fixedly installed on the conveying pipe 31 near the two outlets.
[0034] Two vertical pipes are fixedly installed on the hollow plate 4 near the hot melt tank 2. The same auxiliary heating pipe 44 is fixedly installed on the two vertical pipes. The auxiliary heating pipe 44 is spirally arranged and abuts against the outside of the hot melt tank 2. It can achieve the heat preservation and auxiliary heating effect of the hot melt tank 2 by guiding the hot oil. In order to ensure that the auxiliary heating pipe 44 can maintain a good and stable contact with the outer wall of the hot melt tank 2, thereby achieving efficient heat conduction, the cross-section of the auxiliary heating pipe 44 is rectangular.
[0035] The liquid storage tank 41 is fixedly installed on the bottom inner wall of the tank body 1 and a return pipe 43 is fixedly installed on it, which is connected to the two hollow plates 4 that are away from the hot melt tank 2. A second transfer pump 42 is fixedly installed on the liquid storage tank 41. The inlet of the second transfer pump 42 is connected to the liquid storage tank 41, and the outlet of the second transfer pump 42 is connected to the two hollow plates 4 below the hot melt tank 2. The heating module 5 is set on the liquid storage tank 41.
[0036] In this embodiment, in order to provide stable support for the hollow plate 4 and avoid excessive heat conduction from the hollow plate 4 to the box 1 and thus heat loss, multiple support blocks are fixedly installed on both the front and rear sides of the hollow plate 4, and the multiple support blocks are fixedly connected to the inner wall of the box 1.
[0037] In this embodiment, in order to transfer heat quickly and evenly, thereby improving the use of thermal radiation to transfer heat to the material to achieve preheating and drying operations, the hollow plate 4 is made of a metal material with a thermal conductivity range of 100W / (m·K)-400W / (m·K), such as aluminum, aluminum alloy, copper alloy, etc.
[0038] In this embodiment, in order to collect the mixed rubber that splashes and gathers during the spraying process and facilitate the discharge operation during cleaning, a guide plate with the same inclined top surface is fixedly installed on the bottom of the two partitions 13 that are close to each other and is fixedly connected to the top of the liquid storage tank 41. A discharge pipe is fixedly installed on the front side of the tank body 1, and the inlet position of the discharge pipe is adapted to the lowest point of the top side of the guide plate.
[0039] In this embodiment, in order to facilitate the operator's observation of the process of compounding and bonding the rubber with other materials, and to effectively reduce the possibility of splashing onto the observation window during the spraying process, observation windows are provided on both the front and rear sides of the housing 1, and the observation windows are located above the spraying pipe 32.
[0040] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.
[0041] Working principle: In operation, first, the power is turned on, and heating module 5 is activated to heat the hot oil in storage tank 41. Then, transfer pump 2 42 is activated, and the hot oil is transported by transfer pump 2 42 to the two hollow plates 4 below the hot melt tank 2, and flows through connecting pipe 401 to other hollow plates 4, preheating the materials passing through. Simultaneously, motor 21 is activated to drive stirring frame 22 to stir the compound in the hot melt tank 2, ensuring it is evenly heated to a molten state. Then, transfer pump 3 is activated, and the molten compound is transported by transfer pump 3 to two spray pipes 32, and sprayed through multiple nozzles onto the materials passing through. The material is sprayed and coated on both sides. During the spraying process, the spraying pipe 32 connected to the delivery pipe 31 can be controlled by the control valve 33 to adapt to different spraying requirements. At the same time, the auxiliary heating pipe 44 uses the diversion of hot oil to achieve the heat preservation and auxiliary heating effect of the hot melt tank 2, ensuring that the temperature inside the hot melt tank 2 is suitable. The mixed rubber that splashes and gathers during the spraying process is collected into the storage tank 41 under the action of the guide plate, which facilitates subsequent cleaning and discharge operations. The whole device is easy to operate and has high practicality and applicability, providing an efficient and reliable solution for the compounding of mixed rubber with other materials.
