The two mixing rollers 102 are arranged sequentially along the front and rear direction of the frame 101. The top of the frame 101 is provided with a heat recovery component.
[0025] Please see Figure 1 In this embodiment, the recycling component includes a mounting cover 2 fixedly connected to the top of the frame 101. Heat dissipation fins 3 are fixedly connected to the inner top wall of the mounting cover 2. A recycling pipe 4 is fixedly connected to the left side of the mounting cover 2. A centrifugal fan 5 is fixedly connected to the other end of the recycling pipe 4. A conveying pipe 6 is fixedly connected to the air outlet of the centrifugal fan 5. A material box 7 is fixedly connected to the other end of the conveying pipe 6.
[0026] Specifically, a collection tray 8 is fixedly connected to the inner side of the frame 101. The collection tray 8 is located directly below the rubber mixing roller 102, and the mounting cover 2 is located directly above the rubber mixing roller 102.
[0027] It should be noted that the collection tray 8 is made of high-strength, corrosion-resistant metal material, and the surface of the collection tray 8 is smoothed to facilitate the cleaning of fallen adhesive.
[0028] Specifically, scrapers 9 are fixedly connected to both the front and back of the frame 101, and the scrapers 9 are in contact with the corresponding rubber mixing rollers 102.
[0029] It should be noted that the scraper 9 is made of rubber material with good elasticity and wear resistance, which can closely fit the surface of the rubber mixing roller 102. During the rubber mixing process, the scraper 9 can scrape off the excess rubber material adhering to the surface of the rubber mixing roller 102 in a timely manner as the rubber mixing roller 102 rotates, ensuring the cleanliness of the surface of the rubber mixing roller 102 and improving the quality and efficiency of rubber mixing.
[0030] Specifically, a recycling port is provided on the left side inside the mounting cover 2, and the recycling port is connected to the recycling pipe 4.

[0032] Specifically, a support plate 10 is fixedly connected to the bottom of the centrifugal fan 5, and the support plate 10 is fixedly connected to the left side of the frame 101.
[0033] It should be noted that the support plate 10 is made of sturdy and durable metal material, with sufficient strength and stability to withstand the weight of the centrifugal fan 5 and the vibration during operation.
[0034] Specifically, the material box 7 is fixedly connected to the left side of the frame 101, and a one-way air valve 11 is provided between the material box 7 and the conveying pipe 6.
[0035] It should be noted that the one-way air valve 11 is used to prevent the gas in the material box 7 from flowing back into the conveying pipe 6, ensuring the one-way airflow during the heat recovery process, improving the efficiency of heat transfer, and at the same time preventing the raw materials in the material box 7 from being contaminated by the outside.
[0036] Specifically, the inner left and inner right walls of the material bin 7 are provided with sliding grooves, and a material placement box 12 is slidably connected between the two sliding grooves. A handle is fixedly connected to the front of the material placement box 12, and a drawout port adapted to the material placement box 12 is provided on the front of the inside of the material bin 7.
[0037] It should be noted that the material placement box 12 is made of lightweight and heat-resistant material, which makes it easy to slide and take out in the material box 7.
[0038] Specifically, a filter screen 13 is provided on the inner side of the material bin 7, and the filter screen 13 is located directly above the material placement box 12.
[0039] It should be noted that the filter screen 13 is made of fine metal wire mesh, which has a high-efficiency filtration function. The filter screen 13 is located directly above the material placement box 12, which can effectively block the tiny impurities and particles carried during the heat recovery process and prevent them from entering the material placement box 12 and contaminating the raw materials.
[0040] The working principle of the above embodiments is as follows:
[0041] During the silicone rubber processing and mixing process, the mixing roller 102 rotates under the drive of the power box 103 to mix the silicone rubber. During the mixing process, a large amount of heat is generated between the mixing roller 102 and the silicone rubber. The high-temperature air around the mixing roller 102 is heated and rises, accumulating inside the mounting cover 2. During this process, the heat dissipation fins 3 fixedly connected to the top wall of the mounting cover 2 increase the contact area with the high-temperature air, enabling more efficient heat absorption.
[0042] Next, after the centrifugal fan 5 starts, a negative pressure is formed in the recovery pipe 4, which draws the high-temperature air in the mounting cover 2 into the recovery pipe 4 through the recovery port. Under the action of the centrifugal fan 5, the high-temperature air is transported to the material box 7 through the conveying pipe 6. A one-way air valve 11 is set between the material box 7 and the conveying pipe 6 to ensure that the airflow can only enter the material box 7 from the conveying pipe 6, preventing the gas in the material box 7 from flowing back. After the high-temperature air enters the material box 7, it first passes through the filter screen 13. The filter screen 13 filters out the tiny impurities and particles in the high-temperature air to ensure that the air entering the material placement box 12 is clean. The clean high-temperature air comes into full contact with the raw materials in the material placement box 12, transferring heat to the raw materials and achieving the preheating of the raw materials.
[0043] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
