Description

TECHNICAL FIELD

[0001] The utility model relates to rubber vulcanization equipment field more specifically, relate to a kind of vulcanization production device for long size rubber parts. BACKGROUND

[0002] Vulcanization is a critical step in the rubber industry, which crosslinks linear or branched rubber molecules into a three-dimensional network structure through chemical reactions. This transformation significantly improves the physical properties and chemical stability of rubber products. Specifically, vulcanized rubber products have enhanced pressure resistance, wear resistance, and corrosion resistance on long size rubber parts, with greatly improved elasticity and strength, thereby better adapting to various harsh application environments.

[0003] The vulcanization process of long size rubber parts mainly covers three key stages. The first stage is mixing, which uniformly mixes raw rubber with various additives, laying the foundation for subsequent vulcanization. Only uniform mixing can ensure that rubber molecules have a good reaction basis in subsequent reactions. The second stage is extrusion molding, which uses molds to process the mixed rubber material into the desired shape, determining the basic shape of the rubber product. The final stage is vulcanization, which processes the rubber product in a specific device to complete the final curing process.

[0004] Currently, long size rubber parts are mainly vulcanized using two methods: closed vulcanization and continuous vulcanization production line. Closed vulcanization is suitable for shorter products, such as vulcanization in a closed tank, which precisely controls the temperature, pressure, and time inside the tank to achieve the vulcanization process. This method is better for shorter products, as the internal environment is relatively easy to control. However, for longer long size rubber parts, such as long rubber hoses used in oil and natural gas transportation, fire water bags, and other special industrial applications, continuous vulcanization production lines are more suitable. This method allows long size rubber parts to pass through heating areas one by one on the production line, achieving efficient vulcanization production. However, for long size rubber parts with special quality and performance requirements, continuous vulcanization production lines have obvious drawbacks. Due to the length of long size rubber parts, it is difficult to ensure uniform heating of the entire long size rubber part in the length direction on the production line, which can lead to uneven local vulcanization, affecting product performance and reliability.

[0005] To meet the requirement of uniform vulcanization of long-size rubber parts, large vulcanization tanks (also called vulcanization kettles or vulcanization furnaces) are designed to accommodate and heat the vulcanization of these super-long products. The tank body must have sufficient length and special consideration in structural design to ensure safety and reliability under high pressure conditions. For example, the corner between the tank body sidewall and the sealing cover is treated with a large-radius transition, and the sealing cover is designed as a spherical surface, which are designed to reduce stress concentration and allow uniform pressure distribution. However, this design also has some problems. The long-size rubber parts are arranged in a relatively regular manner after stacking, which cannot fully utilize the space brought by the aforementioned design (large-radius corner between the tank body sidewall and the sealing cover, spherical surface recess of the sealing cover), resulting in low space utilization. During the vulcanization process, a large amount of energy is consumed in the internal empty space, and the exhaust gas emitted during vulcanization also increases, causing serious resource waste. Moreover, these empty spaces cause large pressure and temperature losses during the vulcanization process, which increases the difficulty of process parameter control and makes it difficult to achieve high precision of various vulcanization parameters.

[0006] A sufficient space is required at the inlet of the vulcanization tank because the sealing cover is installed there and no other objects can obstruct the installation, and a certain operation space is also required during the installation of the sealing cover. In this case, for long-size rubber parts, they are currently placed into the vulcanization tank by manual cooperation with hoisting equipment. Due to the long size of the rubber parts, if the hoisting ropes are unevenly tied during hoisting and placing, the long-size rubber parts are prone to deformation and thus generate internal stress; the rubber parts are prone to surface damage if they are bumped during hoisting; as mentioned above, the rubber parts are at high risk of damage during hoisting. Moreover, this method is complicated to operate, cannot realize continuous production, and has low production efficiency. Practical new type content

[0007] The present utility model aims to overcome at least one of the defects of the prior art, and provides a vulcanization production device for long-size rubber parts, which solves the technical problems that the process of transferring long-size rubber parts to a vulcanization tank is complicated, the long-size rubber parts are at high risk of damage, and continuous production cannot be realized without affecting the sealing of the inlet of the vulcanization tank.

[0008] The technical scheme adopted by the present utility model is a vulcanization production device for long-size rubber parts, which comprises: a mounting frame; a conveying platform installed on the mounting frame and used for carrying long-size rubber parts; a vulcanization heating device arranged at the back of the conveying platform; and a lifting platform arranged between the mounting frame and the vulcanization heating device; wherein, when the lifting platform is lifted to a high position, the conveying platform can enter the vulcanization heating device through the lifting platform; and when the lifting platform is lowered to a low position, the inlet of the vulcanization heating device is not affected by the lifting platform and can be sealed.

[0009] The lifting platform is lifted to the high position, the conveying platform carrying the long-size rubber piece enters the vulcanization heating device through the lifting platform, after entering, the lifting platform is lowered to the low position, the sealing cover is installed to seal the vulcanization heating device, the long-size rubber piece on the conveying platform in the interior is vulcanized, and after vulcanization is completed, the sealing cover is disassembled, the lifting platform is lifted to the high position, the conveying platform is pulled out, and the long-size rubber piece after vulcanization is unloaded, so that one vulcanization is completed, and the above process can be repeated to realize continuous production; the design facilitates sealing treatment, simultaneously ensures that the long-size rubber piece can be quickly and efficiently moved into and removed from the vulcanization heating device, realizes efficient operation process, and can effectively improve production efficiency.

[0010] Further, the utility model further comprises a buffer platform, which is arranged side by side on one side of the conveying platform and has a top higher than the top of the conveying platform. The long-size rubber piece during extrusion can be buffered on the buffer platform. After extrusion is completed, the long-size rubber piece on the buffer platform can be rolled onto the conveying platform because the top of the buffer platform is higher than the top of the conveying platform, thereby realizing efficient buffering and transfer of the long-size rubber piece after extrusion. Through cooperation of the online buffer platform, the conveying platform, the lifting platform and the vulcanization heating device, efficient online production is realized, and cumbersome handling work of a traditional vulcanization tank is not needed.

[0011] Further, the guiding device comprises guiding components arranged in the mounting frame, the lifting platform and the vulcanization heating device respectively. When the lifting platform is lifted to the high position, the guiding components in the mounting frame, the lifting platform and the vulcanization heating device are sequentially spliced. A guide component is mounted on the conveying platform and can cooperate with any guiding component arranged on the mounting frame, the lifting platform and the vulcanization heating device. The splicing design of the guiding components ensures smooth transition of the conveying platform in different working states, enhances overall coordination and reliability of the system, and enables the conveying platform to smoothly enter the vulcanization heating device. Cooperation of the guide component and the guiding component reduces friction when the conveying platform moves, improves convenience and adaptability of operation, and ensures smooth transition and efficient transmission of the conveying platform between the guiding components.

[0012] Further, the guiding components are two parallelly arranged guide rails, and the guide component is two guide rollers that are respectively rolled with the two guide rails. A plurality of guide rollers are arranged on the conveying platform. The design of the guide rails and the rollers not only reduces frictional resistance but also provides more stable guiding function, ensures linear motion of the conveying platform, improves running stability of the system, and enables the conveying platform to smoothly enter the vulcanization heating device.

[0013] Further, the conveying platform, the lifting platform and the vulcanization heating pipe are all inclined from front to back and downward, and have the same inclination, and the inclination angle is 0.3-0.7°. When the inclination is 0.3-0.7°, it is more convenient to push the conveying platform, and when the water produced by steam cooling in the vulcanization heating device is discharged from the back, it is more convenient. When the inclination is 0.5°, the effect is best, and it is not too laborious to pull out the conveying platform.

[0014] Further, the conveying platform end is provided with a push-pull plate, and the push-pull plate is detachably provided with a push-pull rod through a push-pull block pin. Through the push-pull rod, the force can be better, and the conveying platform can be moved conveniently. The detachable design is convenient for the conveying platform to enter the next narrow space, avoids interference with other objects around, for example, the conveying platform can be directly moved into the vulcanization heating pipe, and the subsequent conveying, processing and production of long-size rubber parts are more convenient.

[0015] Further, the vulcanization heating device comprises: a vulcanization heating pipeline spliced by several flange pipes; and two sealing covers respectively installed at two ends of the vulcanization heating pipeline. The inner wall of the flange pipe is in a straight cylindrical structure, and the inner side of the sealing cover is a flat surface. The splicing mode of the flange pipe allows the length to be adjusted according to needs, so as to adapt to rubber hoses of different sizes. After installation, the straight cylindrical structure of the inner wall and the flat inner side of the sealing cover can form a vertical surface, which is beneficial to maximize the utilization rate of the internal space, so that the rubber hoses can be arranged more compactly, the empty space is reduced, the uniform distribution of pressure during vulcanization is ensured, the quality of vulcanization is improved, and the energy consumption and waste gas emission are reduced. The spliced flange pipe not only ensures the advantages of long-size rubber parts in product quality consistency, adaptation to special needs and processing of large sizes, but also solves the problem of uneven vulcanization encountered in the production of long-size rubber parts in the continuous vulcanization production line. The spliced flange pipe has obvious advantages in vulcanization quality; specifically, the spliced flange pipe can achieve more uniform vulcanization effect, accurately control the temperature and pressure, ensure that the entire product reaches the ideal vulcanization degree inside and outside, reduce the risk of undercure or overcure, and ensure that the long-size rubber part is uniformly heated. The relatively stable vulcanization environment inside reduces the internal stress caused by rapid heating or cooling, and reduces the possibility of cracks and other defects. The spliced flange pipe is also particularly suitable for special rubber materials, and is easy to adjust process parameters to meet the needs of different materials, and allows the addition of special auxiliary agents or post-processing during vulcanization. Independent control of each batch ensures the consistency of product quality, the closed environment reduces external interference, and the stability and reliability of the product are improved. The flange pipe is welded from standard DN200 stainless steel pipe, which can significantly save project cost, has small processing difficulty and low leakage risk, is easy to use and maintain, and effectively improves the utilization rate of the internal space of the equipment, significantly reduces the amount of steam consumed during the vulcanization process of the hose, and also reduces the amount of waste gas emitted. Due to the more compact overall volume of the tank body, the pressure and temperature control during the vulcanization process of the long-size rubber part is more accurate and stable, which can effectively improve the precision of vulcanization control and the quality of hose vulcanization, and reduce the rate of defective products.

[0016] Further, the vulcanization heating pipeline is provided with a pressure relief valve at the front end and a pneumatic diaphragm regulating valve at the rear end, and a plurality of temperature transmitters are uniformly arranged along the length direction of the vulcanization heating pipeline, two of which are respectively located at the two ends of the vulcanization heating pipeline, and a pressure transmitter is arranged on the pipeline connected with the pneumatic diaphragm regulating valve. The design of these sensors and valves ensures accurate control of temperature and pressure during vulcanization, ensuring the consistency and reliability of product quality. The presence of the pressure relief valve also improves the safety of operation, and the pneumatic diaphragm regulating valve can automatically adjust the air intake according to the data of the pressure transmitter to maintain a constant pressure environment inside. To ensure that the products after vulcanization heating production have better quality and performance.

[0017] Further, the controller can control the opening and closing size of the pneumatic diaphragm regulating valve according to the signals of the temperature transmitter and the pressure transmitter, so that the constant pressure and temperature in the vulcanization heating device are maintained.

[0018] Further, the hydrophobic valve is installed at the low position of the rear end of the vulcanization heating pipeline, which effectively removes the condensed water generated in the vulcanization process, prevents the water from affecting the vulcanization effect, ensures the dryness of the vulcanization environment, further improves the product quality, and reduces the energy waste.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows: the lifting platform is lifted to the high position, the conveying platform bearing the long-size rubber part enters the vulcanization heating device through the lifting platform, then the lifting platform is lowered to the low position, the sealing cover is installed to seal the vulcanization heating device, the long-size rubber part on the conveying platform is vulcanized, after vulcanization, the sealing cover is removed, the lifting platform is lifted to the high position, the conveying platform is pulled out, and the long-size rubber part after vulcanization is unloaded, so that one-time vulcanization is completed, and the above process is repeated to realize continuous production; the design is convenient for sealing treatment, ensures that the long-size rubber part can be quickly and efficiently moved into and removed from the vulcanization heating device, realizes efficient operation process, can effectively improve production efficiency, and can avoid damage to the long-size rubber part during movement.

DETAILED DESCRIPTION

[0028] The drawings of the utility model are only used for exemplary illustration, and cannot be understood as the limitation of the utility model. In order to better illustrate the following embodiments, some components of the drawings can be omitted, enlarged or reduced, and the size of the actual product is not represented; for those skilled in the art, it is understandable that some known structures and their descriptions in the drawings can be omitted.

[0029] As Figures 1-7 shown, the scheme relates to a pipeline vulcanization production line for long-size rubber parts, comprising: a mounting frame 17; a buffer platform 1 and a conveying platform 2 are installed on the mounting frame 17, the conveying platform 2 is arranged on one side of the buffer platform 1, and the top of the conveying platform 2 is lower than the top of the buffer platform 1; a vulcanization heating device is arranged at the back of the conveying platform 2 and comprises a vulcanization heating pipeline 5 and a sealing cover 29, and the vulcanization heating device can select other sealed cylinder, pipeline or tank, etc.; a lifting platform 3 is arranged between the mounting frame 17 and the vulcanization heating device; wherein, when the lifting platform 3 is lifted to a high position, the conveying platform 2 can enter the vulcanization heating device through the lifting platform 3; when the lifting platform 3 is lowered to a low position, the port of the vulcanization heating pipeline 5 is not affected by the lifting platform 3, and the sealing cover 29 can be installed, that is, sealing treatment is carried out. The specific implementation is as follows:

[0030] The mounting frame 17 is a frame structure made of aluminum profile, and the bottom is provided with a lifting-adjustable supporting leg, so that the buffer platform 1 and the conveying platform 2 can be stably adjusted to different inclinations.

[0031] The buffer platform 1 is preferably a buffer roller, which includes a roller frame and a plurality of rotating rollers arranged thereon, or can also be a roller structure, etc. In actual use, it 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.

[0032] 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 (such as rolling) of the long-size rubber part on the buffer platform 1 to the conveying platform 2.

[0033] The guide device includes 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. The guide component 16 is specifically two parallel guide rails. The bottom of the vulcanization heating pipeline 5 is fixed with a mounting plate 26, and the two guide rails are fixed on the mounting plate 26. The guide component 7 is a roller installed at the bottom of the conveying platform 2 and rolling matched with the guide rails, respectively.

[0034] The push-pull plate 11 is installed at the bottom of the front end of the conveying platform 2, and the push-pull rod 9 is detachably installed on the push-pull plate 11 through the push-pull stop pin 10, so as to facilitate the movement of the conveying platform 2.

[0035] Sulfurization heating pipeline 5: As shown in the figure, the sulfurization heating pipeline 5 is spliced by several flange pipes 19, which are pipes with flanges installed at both ends, facilitating mutual connection and sealing of the ends. The sulfurization heating pipeline 5 is installed with a sealing cover 29 at both ends. By adding or subtracting the number of flange pipes 19, the length of the sulfurization heating pipeline 5 can be changed, thereby enabling the vulcanization of rubber parts of any length, improving the scope of application. The flange pipe 19 has a large thickness and can withstand a large pressure. Without special structural modification on the appearance, after using the spliced flange pipe 19, compared with the conventional sulfurization tank, the space utilization rate of the present scheme is improved by 20%, and the steam consumption is reduced by 30%. The sulfurization heating pipeline 5 is inclined downward by 0.3-0.7° from front to back. 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.

[0036] Support structure: A plurality of support structures are provided at the bottom of the sulfurization heating pipeline 5 for fixing the sulfurization heating pipeline 5; the support structure includes a position adjusting assembly and a height adjusting assembly 8; the position adjusting assembly is used to adjust the front and rear positions of the sulfurization heating pipeline 5, and the height adjusting assembly 8 is used to adjust the height of the sulfurization heating pipeline 5. The support structure provides flexible adjustment capability through the position adjusting assembly and the height adjusting assembly 8, ensuring that the sulfurization heating pipeline 5 can be accurately adjusted to the required height and position. This not only improves the adaptability and operation convenience of the equipment, for example, by adjusting the support structure to incline the sulfurization heating pipeline 5, it is convenient to discharge the condensed water inside, reducing the operation difficulty and time waste caused by height or position mismatch.

[0037] The height adjusting assembly 8 includes: a base 6; a fixed plate 31 fixed on the base 6, each fixed plate 31 is provided with not less than two screw rods, and each screw rod is threadedly connected with two nuts; an activity plate 32 provided with a through hole corresponding to the position of the screw rod, the through hole is sleeved on the screw rod, and the two nuts on each screw rod are located between the two nuts.

[0038] The position adjusting assembly includes a pipeline support roller 18 mounted on the movable plate 32 and rolling with the bottom of the vulcanization heating pipeline 5, and a U-shaped pipe clamp 30 with threaded ends mounted on the movable plate 32 through nuts to fix the vulcanization heating pipeline 5 on the movable plate 32. The position adjusting assembly realizes flexible adjustment of the front and rear positions of the vulcanization heating pipeline 5 through the cooperation of the pipeline support roller 18 and the U-shaped pipe clamp 30. The pipeline support roller 18 reduces the friction force, making the position adjustment more easy, while the U-shaped pipe clamp 30 ensures the firm fixation of the vulcanization heating pipeline 5, preventing loosening and displacement, and ensuring stable operation of the equipment.

[0039] The environmental parameter monitoring device is arranged on the vulcanization heating pipeline 5 and is used for real-time monitoring of internal temperature and pressure, and includes a plurality of temperature monitoring devices and pressure monitoring devices. The temperature monitoring devices are evenly arranged along the length direction of the vulcanization heating pipeline 5. The temperature monitoring devices can be temperature sensors or temperature transmitters 25, and the pressure monitoring devices can be pressure sensors or pressure transmitters 24.

[0040] The pressure and fluid control system is arranged on one side of the vulcanization heating pipeline 5 and includes at least one pressure adjusting device for accurately controlling the air pressure in the vulcanization heating pipeline 5, at least one pressure relief device for quickly releasing the gas in the vulcanization heating pipeline 5 when necessary, and at least one drainage device for draining the condensed water vapor or other unnecessary fluids generated in the vulcanization process. The pressure adjusting device is a pneumatic diaphragm regulating valve 23 installed at the top of the rear end of the vulcanization heating pipeline 5, the pressure relief device is a pressure relief valve 20 installed at the top of the front end of the vulcanization heating pipeline 5, and the drainage device is a drain valve 22 installed at the bottom of the rear end of the heating pipeline for draining condensed water to avoid heat absorption affecting the internal temperature. The selection of the pressure adjusting device, the pressure relief device and the drainage device belongs to the routine selection of those skilled in the art, which will not be described in detail here. The manual drainage valve 21 and the manual pressure relief valve 14 are also included for manual drainage and manual pressure relief, which are respectively installed at the bottom and top of the rear end of the vulcanization heating pipeline 5 to ensure safe operation.

[0041] The controller 4 is also included, which can automatically adjust the opening and closing size of the pneumatic diaphragm regulating valve 23 according to the signals of the temperature transmitter 25 and the pressure transmitter 24 to ensure the stability of the temperature and pressure in the vulcanization process.

[0042] Lifting platform 3: set between the mounting frame 17 and the vulcanization heating pipeline 5, specifically, mounted on the lifting platform support 12, the lifting guide rod 13 and the lifting cylinder 15 are installed on the lifting platform support 12 and can slide up and down. The lifting platform 3 is fixedly connected with the top end of the lifting guide rod 13 and the telescopic end of the lifting cylinder 15. When the lifting platform 3 is lifted to the high position, the conveying platform 2 can enter the vulcanization heating pipeline 5 through the lifting platform 3; when it is lowered to the low position, the port of the vulcanization heating pipeline 5 is not affected, and the sealing cover 29 can be installed for sealing treatment.

[0043] Working principle:

[0044] Firstly, the end of the long-size rubber part extruded by the extruder falls on the buffer roller, moves forward with the rotation of the rotating roller, is cut off and stopped extruding after reaching the set length. After the formed long-size rubber part is cooled for a period of time, it is pushed to the conveying platform 2, and after accumulating a certain amount, the conveying platform 2 carries the long-size rubber part to move to the vulcanization heating pipeline 5 through the lifting platform 3, then the lifting platform 3 is lowered, the port of the vulcanization heating pipeline 5 is sealed with the sealing cover 29, and the heating vulcanization is started. After completion, the pressure is released, the sealing cover 29 is opened, and the vulcanized long-size rubber part is taken out, and the next batch is ready.

[0045] The inner wall of the flange pipe 19 adopts a straight cylinder type design, the inner side of the sealing cover 29 is a flat surface, after installation, the flat surface of the sealing cover 29 is perpendicular to the inner wall of the flange pipe 19, the internal shape is regular, the long-size rubber part can be arranged more tightly, and the unnecessary empty space is reduced, and the risk of pressure loss is reduced. Smaller empty space means that the internal environment is more stable, temperature and pressure are easier to control, the precision of each parameter of vulcanization can be controlled more accurately, and the consistency of the vulcanization process and product quality are ensured.
