Description

Technical Field

[0001] The invention relates to the field of rubber product pretreatment, in particular to a method for pretreatment of rubber raw materials for tires. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight, greater than hundreds of thousands.

[0003] Rubber is divided into two types: natural rubber and synthetic rubber. Rubber sheet is a sheet product with a certain thickness and a large area made of rubber as the main material (it may contain reinforcing materials such as fabrics and metal sheets) through vulcanization, referred to as rubber sheet.

[0004] At present, when we process rubber products, we need to pre-treat them. If the rubber sheet is not subjected to calendering treatment, it may split. For this reason, we propose a pre-treatment method for rubber raw materials for tires. Summary of the invention

[0005] The object of the present invention is to provide a method for pretreating rubber raw materials for tires to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, a method for preprocessing rubber raw materials for tires includes a rubber processing platform and a processing method, wherein a hot pressing structure capable of hot pressing preprocessing a rubber sheet is disposed at the upper end of the rubber processing platform, a pushing structure capable of pushing the rubber sheet is installed on the outer wall of the rubber processing platform, a rolling structure capable of rolling and integrating the rubber sheet is installed at the front end of the rubber processing platform, a moving structure capable of moving the rubber sheet is installed on one side of the rubber processing platform, and a cutting structure and a rubber supporting structure capable of processing the rubber sheet are installed inside the moving structure;

[0007] The steps of the processing method are:

[0008] S1, rubber sheet rolling;

[0009] S2, rubber sheet compaction;

[0010] S3, rubber plate push;

[0011] S4, rubber sheet moves;

[0012] S5. Rubber sheet cutting.

[0013] Preferably, the hot pressing structure includes a hot pressing platform, a hydraulic structure and a hot pressing plate. The hot pressing platform is arranged directly above the rubber processing platform. The hydraulic structure is fixedly installed on the top of the hot pressing platform. The hydraulic structure includes a hydraulic cylinder and a hydraulic cylinder. The hot pressing plate is integrally connected to the bottom of the hot pressing platform, and the hot pressing plate is integrally connected to the bottom of the hot pressing platform, which ensures stability and uniformity during the hot pressing process. The surface of the hot pressing plate is covered with a layer of high temperature resistant and wear resistant material, which can effectively resist the high temperature and friction generated during the rubber processing process, thereby extending the service life of the hot pressing plate. In addition, the hot pressing plate is designed with an efficient heating system inside, which can quickly heat up and maintain a constant temperature, providing a stable heat source for rubber processing.

[0014] Preferably, the pushing structure includes a fixed plate, a hydraulic rod and a movable push plate, the fixed plate is fixedly connected to the outer wall of the rubber processing platform, the hydraulic rod is fixedly connected to one end of the fixed plate, the number of the hydraulic rods is two, the movable push plate is fixedly connected to the hydraulic rod, the movable push plate is movably connected to the surface of the rubber processing platform, and the design of the movable push plate takes into account the shape and size of the rubber processing platform to ensure that force can be applied evenly and stably during the pushing process.

[0015] The surface of the movable push plate is covered with a layer of anti-slip material to prevent unnecessary friction with the rubber material during the pushing process, thereby affecting the processing quality.

[0016] Preferably, the rolling structure includes a fixed column, a variable frequency motor, a transmission belt, a rotating shaft, a rolling rod A, a rolling rod B and a heating plate. The fixed column is arranged on one side of the rubber processing platform. The variable frequency motor is fixedly installed inside the fixed column. The transmission belt is connected to one end of the variable frequency motor. The other end of the transmission belt is connected to a rotating shaft. The rotating shaft is rotatably connected between the fixed columns. The outer side of the rotating shaft is fixedly connected to the rolling rod A. The rolling rod B is installed above the rolling rod A. The rolling rod A and the rolling rod B have the same size. The heating plate is fixedly installed on the inner wall of the rolling rod A. The number of the heating plates is several. The variable frequency motor is the core power source of this system. Its precise speed control ensures the stable operation of the transmission belt. The transmission belt is responsible for transmitting the power of the motor to the rotating shaft, realizing the stable rotation of the rotating shaft. This design allows the rotation speed of the rotating shaft to be accurately adjusted according to the processing requirements, further ensuring the accuracy and uniformity of the rubber material processing.

[0017] The combination of the rolling rod A and the rolling rod B provides the necessary pressure for the rubber material. Their consistent sizes ensure that the rubber material can be subjected to uniform pressure during the rolling process, thereby avoiding deformation or damage of the material due to uneven pressure.

[0018] Heating plates play a vital role in the calendering process. They are fixed on the inner wall of the calendering rod A and heat the rubber material by generating heat. This heating method can quickly and evenly increase the temperature of the rubber material, making it easier to calender.

[0019] Preferably, the mobile structure includes a processing box, a rubber outlet, a support column and a conveyor belt. The processing box is fixedly installed on one side of the rubber processing platform, the rubber outlet is clamped at one end of the processing box, the support column is fixedly connected to the bottom of the processing box, the number of the support columns is several, the conveyor belt is rotatably connected to the inside of the processing box, the number of the conveyor belts is two, and the two conveyor belts are arranged in parallel and opposite to each other, respectively located on both sides of the inside of the processing box. The surface of the conveyor belt is evenly distributed with fine protrusions, which are designed to increase the friction between the rubber raw materials and prevent the raw materials from slipping during the transmission process.

[0020] A cutting device is provided at the rubber outlet. When the rubber is transported to the outlet via the conveyor belt, the cutting device will automatically cut the rubber.

[0021] Preferably, the cutting structure includes a cutting gear, a motor housing and a driving motor, the cutting gear is rotatably connected to the inside of the processing box, the cutting gear is transmission-connected to one end of the driving motor, the motor housing is fixedly installed inside the processing box, and the driving motor is fixedly installed inside the motor housing. Under the careful protection of the motor housing, the driving motor stably provides powerful power to ensure that the cutting gear operates at a stable speed inside the processing box.

[0022] In order to further improve cutting efficiency, we have specially designed optimized gear tooth profiles and cutting blades. The cutting gear tooth profile has been precisely calculated to ensure cutting accuracy while minimizing friction and resistance, thereby reducing energy consumption. The cutting blade is made of high-hardness, high-wear-resistant alloy material, which not only ensures the sharpness of the cutting, but also maintains stable performance during long-term work.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention can achieve efficient and accurate pretreatment of rubber sheets through a series of carefully designed structures and steps, thereby improving the production efficiency and quality of rubber products. Specifically, the advantages of the present invention in the pretreatment of rubber raw materials are mainly reflected in the following aspects:

The combination of the hot pressing platform, hydraulic structure and hot pressing plate enables the rubber sheet to be pretreated at a constant temperature and pressure, thereby effectively removing impurities in the rubber sheet, improving its physical properties and providing a good foundation for subsequent processing.

[0027] The design of the pushing structure enables the rubber sheet to be pushed automatically during the pretreatment process, greatly reducing the labor intensity of the operator. The movable push plate of the hydraulic rod can achieve smooth pushing of the rubber sheet, ensuring that the rubber sheet will not be dislocated or deformed during the pretreatment process.

[0028] The design of the calendering structure further improves the pretreatment effect of the rubber sheet. Through the combination of the variable frequency motor, the transmission belt, the rotating shaft, the calendering rod A, the calendering rod B and the heating plate, the continuous calendering treatment of the rubber sheet can be achieved, and heating can be performed during the calendering process, further improving the physical properties of the rubber sheet and improving its processing performance.

[0029] In addition, the design of the moving structure and cutting structure enables the rubber sheet to be automatically moved and cut after pretreatment, realizing automated production.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-5 , a method for pre-processing rubber raw materials for tires shown in the figure, including a rubber processing platform 1 and a processing method, wherein a hot pressing structure 2 capable of pre-processing a rubber sheet by hot pressing is arranged at the upper end of the rubber processing platform 1, a pushing structure 3 capable of pushing the rubber sheet is installed on the outer wall of the rubber processing platform 1, a rolling structure 4 capable of rolling and integrating the rubber sheet is installed at the front end of the rubber processing platform 1, a moving structure 5 capable of moving the rubber sheet is installed on one side of the rubber processing platform 1, and a cutting structure 6 and a rubber supporting structure 7 capable of processing the rubber sheet are installed inside the moving structure 5;

[0039] The hot pressing structure 2 is a key step in rubber pretreatment. This structure consists of a high-precision temperature control system and a powerful pressure applicator. After the rubber sheet is fed into the hot pressing structure 2, it will be hot pressed according to the preset temperature and pressure parameters. This process aims to change the physical properties of the rubber, such as hardness, ductility and resilience, to meet the needs of subsequent processes.

[0040] The calendering structure 4 is a device for further processing the rubber sheet. This process helps to improve the surface quality and structural performance of the rubber sheet, making it more in line with the requirements of subsequent processing.

[0041] The cutting structure 6 is an important part in the pretreatment process of rubber raw materials. It is equipped with high-precision cutting tools and automatic control systems, which can accurately cut the rubber sheet according to the preset cutting parameters. This process not only improves production efficiency, but also ensures the dimensional accuracy and shape consistency of the rubber sheet.

[0042] The steps of the processing method are:

[0043] S1, rubber sheet rolling;

[0044] S2, rubber sheet compaction;

[0045] S3, rubber plate push;

[0046] S4, rubber sheet moves;

[0047] S5. Rubber sheet cutting.

[0048] The hot pressing structure 2 includes a hot pressing platform 21, a hydraulic structure 22 and a hot pressing plate 23. The hot pressing platform 21 is arranged directly above the rubber processing platform 1. The hydraulic structure 22 is fixedly installed on the top of the hot pressing platform 21. The hydraulic structure 22 includes a hydraulic cylinder and a hydraulic cylinder. The hot pressing plate 23 is integrally connected to the bottom of the hot pressing platform 21.

[0049] Specifically, the hot pressing platform 21 is made of high-strength alloy material to ensure that the structural performance can be maintained stably under long-term high-temperature working environment. Its surface is specially treated to have excellent high-temperature resistance and corrosion resistance, effectively extending the service life.

[0050] The hydraulic structure 22 is a key component of the hot pressing structure 2. It uses a precise hydraulic control system to ensure that the hot pressing plate 23 can remain stable and accurate during the lifting process. The hydraulic cylinder is driven by high-pressure oil and provides strong power support, so that the hot pressing plate 23 can quickly and accurately reach the predetermined position. At the same time, the design of the hydraulic cylinder fully considers safety and reliability, and can ensure the safety of operators even in emergencies.

[0051] The pushing structure 3 includes a fixed plate 31, a hydraulic rod 32 and a movable push plate 33. The fixed plate 31 is fixedly connected to the outer wall of the rubber processing platform 1. The hydraulic rod 32 is fixedly connected to one end of the fixed plate 31. There are two hydraulic rods 32. The movable push plate 33 is fixedly connected to the hydraulic rod 32.

[0052] The rolling structure 4 includes a fixed column 41, a variable frequency motor 42, a transmission belt 43, a rotating shaft 44, a rolling rod A45, a rolling rod B46 and a heating plate 47. The fixed column 41 is arranged on one side of the rubber processing platform 1. The variable frequency motor 42 is fixedly installed inside the fixed column 41. The transmission belt 43 is transmission-connected to one end of the variable frequency motor 42. The other end of the transmission belt 43 is connected to a rotating shaft 44. The rotating shaft 44 is rotatably connected between the fixed columns 41. The outer side of the rotating shaft 44 is fixedly connected to a rolling rod A45. A rolling rod B46 is installed above the rolling rod A45. The rolling rod A45 and the rolling rod B46 have the same size. The heating plate 47 is fixedly installed on the inner wall of the rolling rod A45. The number of the heating plates 47 is several.

[0053] Specifically, the variable frequency motor 42 serves as the power source of the rolling structure 4, and through its precise frequency adjustment, it realizes the variable speed drive of the transmission belt 43. This variable speed drive enables the rotating shaft 44 to rotate at different speeds according to the processing requirements, thereby meeting the rolling requirements of different rubber materials or different processing stages.

[0054] The rolling rod A45 and the rolling rod B46 are the execution parts of the rolling structure 4. The same size design ensures balanced force during the rolling process and avoids deformation or damage of the rubber material caused by uneven force. At the same time, the close cooperation between the rolling rod A45 and the rolling rod B46 ensures stability and precision during the rolling process.

[0055] The design of the heating plate 47 further improves the rolling effect. The heating plate 47 heats the inner wall of the rolling rod A45, so that the rubber material can be appropriately softened during the rolling process, making it easier to be compressed and shaped by the rolling rod A45 and the rolling rod B46. The number of heating plates 47 is set to a plurality, ensuring uniform heating of the inner wall of the rolling rod A45, further improving the rolling effect.

[0056] The mobile structure 5 includes a processing box 51, a rubber outlet 52, a support column 53 and a conveyor belt 54. The processing box 51 is fixedly installed on one side of the rubber processing platform 1, the rubber outlet 52 is clamped at one end of the processing box 51, the support column 53 is fixedly connected to the bottom of the processing box 51, and the number of the support columns 53 is several. The conveyor belt 54 is rotatably connected to the inside of the processing box 51, and the number of the conveyor belts 54 is two.

[0057] The cutting structure 6 includes a cutting gear 61, a motor housing 62 and a driving motor 63. The cutting gear 61 is rotatably connected to the inside of the processing box 51. The cutting gear 61 is transmission-connected to one end of the driving motor 63. The motor housing 62 is fixedly installed inside the processing box 51. The driving motor 63 is fixedly installed inside the motor housing 62.

[0058] The rubber supporting structure 7 includes an electric push rod 71 and a supporting plate 72. The electric push rod 71 is fixedly mounted on the inner wall of the processing box 51. There are two processing boxes 51. The rubber outlet 52 is fixedly connected to one end of the processing box 51. There are two rubber outlets 52.

[0059] Embodiment 1:

[0060] When the rubber sheet moves to the vicinity of the cutting structure 6 driven by the conveyor belt 54, the electric push rod 71 starts to work, pushing the supporting plate 72 to move toward the rubber sheet, ensuring that the rubber sheet remains stable during the cutting process and preventing cutting errors caused by movement or shaking. The material of the supporting plate 72 needs to be wear-resistant, high-temperature resistant, and non-chemically reactive when in contact with the rubber material to ensure the quality of the rubber sheet.

[0061] When the rubber sheet is stably stopped in the cutting area, the driving motor 63 is started to drive the cutting gear 61 to rotate. The tooth shape and rotation speed of the cutting gear 61 need to be adjusted according to the material and thickness of the rubber sheet to ensure the flatness and accuracy of the cutting surface. At the same time, a dust suction device is provided inside the processing box 51 to absorb the rubber dust generated during the cutting process and keep the working environment clean.

[0062] The cut rubber sheet is continuously driven by the conveyor belt 54 and is discharged through the rubber outlet 52. At this time, the support plate 72 is reset under the drive of the electric push rod 71, waiting for the arrival of the next rubber sheet. The design of the rubber outlet 52 needs to consider the size and shape of the rubber sheet to ensure that the rubber sheet can be smoothly discharged without damage.

[0063] After the above steps, the rubber raw materials are effectively pretreated, providing high-quality raw materials for subsequent production and processing. The entire pretreatment process is highly automated and easy to operate, which improves production efficiency and product quality. At the same time, the close cooperation and efficient collaboration between the various structures also ensure the stability and reliability of the entire pretreatment process.

[0064] Embodiment 2:

[0065] S1. Rubber sheet rolling:

[0066] In this step, the variable frequency motor 42 is started, driving the transmission belt 43 to rotate, thereby driving the rotating shaft 44 to start rotating. The rolling rod A45 and the rolling rod B46 move up and down with the rotation of the rotating shaft 44, and the rubber sheet passing through is rolled and integrated. At the same time, the heating plate 47 provides an appropriate temperature to help the rubber sheet to be smoother during the rolling process and enhance the performance of the rubber sheet.

[0067] S2. Rubber sheet compaction:

[0068] After the rubber sheet is rolled, it enters the hot pressing structure 2 for compaction. The hydraulic structure 22 drives the hot pressing platform 21 to descend, and the hot pressing plate 23 performs hot pressing on the rubber sheet to discharge the air inside the rubber sheet, making the rubber sheet more compact and improving the density and strength of the rubber sheet.

[0069] S3, rubber plate push:

[0070] The compacted rubber sheet needs to be pushed by the pushing structure 3 to enter the next process. The hydraulic rod 32 pushes the movable push plate 33 to slide on the surface of the rubber processing platform 1 to push the rubber sheet to a predetermined position.

[0071] S4, rubber sheet movement:

[0072] The pushed rubber sheet enters the moving structure 5 and is moved by the conveyor belt 54. Driven by the conveyor belt 54, the rubber sheet is transported to the position of the cutting structure 6 and the rubber supporting structure 7.

[0073] S5. Rubber sheet cutting:

[0074] In the cutting structure 6, the driving motor 63 is started, driving the cutting gear 61 to rotate and cut the rubber sheet. At the same time, the electric push rod 71 of the rubber supporting structure 7 pushes the supporting plate 72 to support the rubber sheet to prevent the rubber sheet from deflecting or deforming during the cutting process. After the cutting is completed, the rubber sheet is discharged from the rubber outlet 52, completing the entire processing flow.
