Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vulcanized rubber part buffer transfer equipment, more particularly to a buffer transfer device for extruding long-size rubber parts. BACKGROUND

[0002] Vulcanization is a critical step in the rubber industry, through chemical reaction, linear or branched rubber molecules are cross-linked into a three-dimensional network structure, thereby significantly improving the physical properties and chemical stability of rubber products. Vulcanization not only enhances the pressure resistance, wear resistance and corrosion resistance of long-size rubber parts, but also greatly improves the elasticity and strength, making it more suitable for various harsh application environments.

[0003] The vulcanization process of long-size rubber parts usually consists of three main stages: first, mixing, which involves uniformly mixing raw rubber with various additives; second, extrusion molding, which uses a mold to shape the mixed rubber material into the desired form; and finally, vulcanization, which involves treating the rubber product in a specific device to complete the final curing process.

[0004] Currently, there are two main ways to vulcanize long-size rubber parts: closed mode vulcanization and continuous vulcanization production line. Closed mode vulcanization is suitable for products with relatively small lengths, such as vulcanization in a closed tank, which controls temperature, pressure and time to achieve the vulcanization process. For longer long-size rubber parts, such as long rubber hoses used in special industrial applications such as oil and natural gas transportation, fire water bags, etc., continuous vulcanization production line is more suitable. This method allows long-size rubber parts to pass through heating areas one by one in a production line, achieving efficient vulcanization production. However, for long-size rubber parts with special quality and performance requirements, continuous vulcanization production lines are difficult to ensure uniform heating throughout the length of the long-size rubber part, resulting in uneven local vulcanization and affecting the performance and reliability of the product.

[0005] To meet the requirement of uniform vulcanization of long-size rubber parts, large-scale vulcanization tanks (also known as vulcanization kettles or vulcanization furnaces) are designed to accommodate and heat these super-long products. This requires the extruder to first extrude long-size rubber parts and then move them into the large-scale vulcanization tank. Due to the excessive length of long-size rubber parts, to prevent them from being damaged by bending during transfer, manual assistance is usually required for lifting equipment to load and unload, which is very inefficient when loading and unloading the vulcanization tank. During production, the operation from extruding long-size rubber parts to transferring is also very cumbersome, resulting in low production efficiency. SUMMARY

[0006] The utility model aims at overcoming at least one of the above prior art defects, provide a kind of for extruding long size rubber piece buffer transfer device, for solving the operation from extruding long size rubber piece to transfer in production process is very tedious, resulting in low production efficiency, in the process of transfer, it is prone to produce bending damage technical problem.

[0007] The utility model adopts technical scheme, a kind of for extruding long size rubber piece buffer transfer device, comprising: mounting bracket;Buffer roller, it is installed on mounting bracket, one end is set below extruder outlet, several rotating rollers are equipped on it;Guide component, it is fixed on mounting bracket;Conveying platform, it is movably installed on guide component, and it is arranged side by side in buffer roller side, and its top is lower than the top of buffer roller.

[0008] When extruding, extruded long size rubber piece gradually moves to buffer roller, and provides rolling friction by rotating roller on it, to move forward, when a long size rubber piece is completely extruded, cut off and stop extruding, long size rubber piece formed by extrusion is completely placed on buffer roller, then long size rubber piece formed on buffer roller is rolled to conveying platform, so repeat operation, until when the quantity of enough vulcanization is accumulated on conveying platform, stop.Afterwards, conveying platform is pushed to move on guide component and cross to the guide component of other platform, long size rubber piece transfer purposes can be realized, such as moving into subsequent vulcanization heating pipeline.The buffer roller in the scheme need not be set power, need not consume energy, can effectively save cost;By using buffer roller, the resistance that long size rubber piece moves is small, and deformation and internal stress cannot be generated, and the quality thereof can be effectively improved.Long size rubber piece after extrusion can be easily moved to conveying platform, when accumulated to certain amount, under the guidance of guide component, long size rubber piece can be easily moved to other positions by conveying platform, can effectively reduce transfer difficulty, improve transfer efficiency.In the scheme, the efficient buffer transfer of long size rubber piece is realized by the cooperation of buffer roller and conveying platform, can effectively improve the production efficiency of long size rubber piece, and long size rubber piece is not prone to bending damage in the process of transfer.

[0009] Further, the guide component includes two guide rails arranged side by side on the mounting bracket, and guide rollers are installed on the conveying platform to rollingly engage the two guide rails. A plurality of rollers are provided on the conveying platform. The design of guide rails and rollers not only reduces the frictional resistance but also provides more stable guiding function, ensuring the stability of the conveying platform operation, so that the conveying platform can be smoothly moved to other components. The guide component can also be a sliding groove, and the conveying platform bottom is provided with a sliding block matched with the sliding groove. It can also be other ways to move the conveying platform, which is a conventional technical means in the art and will not be described in detail here.

[0010] Further, the roller is installed on the conveying platform through high-temperature-resistant ceramic bearings. Because the extruded rubber part has a high temperature and the long-size rubber part has a large weight, the general bearings are easily damaged and have a very short service life. The high-temperature-resistant ceramic bearings have excellent properties such as high hardness, high strength, high-temperature resistance and high wear resistance due to their unique material properties and structural design. The use of high-temperature-resistant bearings can enable the conveying platform to operate stably for a long time under heavy load conditions. The high-temperature-resistant bearings can be selected from: silicon nitride (Si3N4) ceramic bearings, zirconium oxide (ZrO2) ceramic bearings, silicon carbide (SiC) ceramic bearings, etc.

[0011] Further, the conveying platform end is provided with a push-pull plate, and a push-pull rod is detachably installed on the push-pull plate through a push-pull stop pin. The push-pull rod can better exert force and facilitate the movement of the conveying platform. The detachable design facilitates the entry of the conveying platform into the next narrow space and avoids interference with other objects around, for example, the conveying platform can be directly moved into the vulcanization heating pipeline, which is more convenient for the subsequent conveying, processing and production of long-size rubber parts.

[0012] Further, the mounting frame is a frame structure made of aluminum profiles, and the top surface has a profile groove body perpendicular to the length direction of the buffer roller way. The guide component and the buffer roller way are respectively installed in the profile groove body through a plurality of bolt assemblies. The bolt assembly can be in the form of a bolt cooperating with a T-shaped nut or in the form of a plug-in nut cooperating with a bolt, which belongs to the conventional technical means in the field. By loosening the bolt and moving the nut in the profile groove body, the distance between the buffer roller way and the guide component can be adjusted, that is, the distance between the buffer roller way and the conveying platform can be changed. When the width or diameter of the long-size rubber part is large, the distance between the buffer roller way and the conveying platform can be appropriately increased, and when the width of the long-size rubber part is small, the distance between the buffer roller way and the conveying platform can be reduced, so that the long-size rubber part can be more smoothly moved onto the conveying platform.

[0013] Further, a plurality of mounting seats are fixed to the bottom of the mounting frame, and each mounting seat is provided with a liftable leg. The height of the mounting frame can be adjusted through the liftable leg, so that it can be applied to other use scenarios with different height requirements.

[0014] Further, the conveying platform and the buffer roller way are inclined from front to back and downward, and have the same inclination, and the inclination angle is 0.3-0.7°, preferably 0.5°. This inclination is more labor-saving and can prevent the occurrence of slope sliding when the inclination is too large.

[0015] Further, the conveying platform is in U-shaped cross section and is made of aluminum alloy material. The U-shaped structure can prevent the long-size rubber piece from rolling off, the aluminum alloy material has excellent heat dissipation performance and smooth surface, and will not damage the long-size rubber piece.

[0016] Compared with the prior art, the beneficial effects of the utility model are that: the buffer roller way in the scheme does not need to be provided with power and does not need to consume energy, so that the cost can be effectively saved; the buffer roller way is adopted, the resistance of the long-size rubber piece during movement is small, deformation and internal stress are not generated, and the quality can be effectively improved. The long-size rubber piece after extrusion can be easily moved to the conveying platform, when accumulated to a certain amount, under the guidance of the guide part, the long-size rubber piece can be easily moved to other positions through the conveying platform, the transfer difficulty can be effectively reduced, and the transfer efficiency is improved. In the scheme, the efficient buffering and transfer of the long-size rubber piece are realized through the cooperation of the buffer roller way and the conveying platform, the production efficiency of the long-size rubber piece can be effectively improved, and the long-size rubber piece is not easy to be damaged by bending during transfer.

Specifically as follows:

[0027] The mounting frame 17 is a frame structure made of aluminum profile, and the bottom is provided with adjustable supporting legs, so that the buffer platform 1 and the conveying platform 2 can be stably adjusted to different inclinations.

[0028] The buffer platform 1 is preferably a buffer roller, which comprises a roller frame and a plurality of rotating rollers arranged thereon, or a roller structure, etc. In actual use, the buffer platform 1 is arranged at the outlet position of the extruder and does not need to be powered. During extrusion, the extruded long-size rubber part is gradually moved onto the buffer platform 1 and is provided with rolling friction by the rotating rollers thereon to move forward. When a long-size rubber part is completely extruded, the extrusion is cut off and stopped, and the extruded long-size rubber part is completely placed on the buffer platform 1. Then the extruded long-size rubber part on the buffer platform 1 is rolled onto the conveying platform 2, and the operation is repeated until a sufficient number of vulcanized products are accumulated on the conveying platform 2.

[0029] The conveying platform 2 is a U-shaped long-slot body made of aluminum alloy material. The top surface of the mounting frame 17 has a profile slot 27 perpendicular to the length direction of the buffer roller, and the buffer roller is mounted in the profile slot 27 through a plurality of bolt assemblies 28. The conveying platform 2 is arranged on one side of the buffer platform 1 and has a top lower than that of the buffer platform 1, so as to facilitate the movement (e.g. rolling) of the long-size rubber part on the buffer platform 1 to the conveying platform 2.

[0030] The guide device comprises a guide component 16 and a guide component 7. The guide component 16 is arranged in the mounting frame 17, the lifting platform 3 and the vulcanization heating pipeline 5, respectively. When the lifting platform 3 is lifted to a high position, the guide components 16 in the mounting frame 17, the lifting platform 3 and the vulcanization heating pipeline 5 are sequentially spliced. The guide component 7 is installed on the conveying platform 2 and can cooperate with any guide component 16 arranged in the mounting frame 17, the lifting platform 3 and the vulcanization heating pipeline 5.

Through experimental verification, when the inclination angle is 0.3-0.7°, the pushing resistance of the conveying platform 2 is reduced by about 20% and there is no slope sliding phenomenon. The optimal inclination is 0.5°, which can reduce the residual amount of condensed water by 95%, and is the best inclination angle. At the same time, a slight inclination angle helps to reduce friction, making it easier for the conveying platform 2 to enter the sulfurization heating pipeline 5, and it will not be very laborious when pulled out.
