Application fields of silicone open mill

Silicone open mill, also known as open rubber mixing machine, is a specially developed open mill for silicone materials. This model is widely used in medical products, electronic products, sports watch straps, silicone buttons, medical equipment, silicone tubes, food, sealing rings, high and low voltage electronics, sealing strips, maternal and child products, daily necessities industries, and more; The plasticization, mixing, and vulcanization molding of raw materials such as silicone rubber.

Advantages of Silicone Open Refining Machine Technology

[Safety device]

Improvement of the safety device of the open mill: In addition to emergency brake switches at the four corners of the open mill, there is a chest collision switch in front of the roller that is level with the working surface. If the operator accidentally tilts their body forward and touches the chest collision switch in front of the roller, the two rollers will immediately stop and reverse outward without disassembling the rollers. After restarting, the open mill can ensure normal operation and overcome the problem of transmission device damage caused by the inability or reverse rotation of the rollers in the industry. Maximum protection for the personal safety of rubber technicians, convenient multi brake braking, and humanized operation design! (There is a foot kick safety device to choose from, and traditional hand pull rod type can also be used according to customer preferences)

【 Roller 】

Material: Made of high-quality carbon steel with a hardness (HRC) of 68-75, fast heat transfer, high carbon content, hard, wear-resistant and durable, not easy to pull rollers.

Roller surface treatment: heat treatment and tempering - deep nitriding for 72 hours - electroplating hard chromium, polishing hard chromium to a thickness of 0.12~0.18mm (mirror treatment can also be done, suitable for materials with high viscosity and difficult to clean)

Roller inner cavity: precision machining, hollow enclosed water flow, spiral heat transfer to ensure rapid and uniform temperature rise or fall of the roller body, so as to maintain precise temperature control.

[Technological Breakthrough]

1. Segmented mixing timer

This invention can be freely set based on the required time for each batch of materials (for example, the time required for your company to refine one batch of rubber is 300 seconds, and when the agreed time is reached, an audible and visual alarm will be triggered). This invention ensures that the quality of each batch of rubber is stable and consistent, overcoming the problem of uneven product quality caused by manual judgment in the past due to the lack of unified experience and technology of each rubber mixing technician, reducing labor costs, and avoiding unnecessary loss of rubber material costs for customers.

2. Automatic refueling reminder device

This device has the advantage of ensuring long-term oil supply to transmission components, compensating for the serious consequences of forgetting to refuel manually or not knowing when the oil shortage will cause damage to components, and maximizing the service life of machinery.

[Design Professionalism]

Peers: The transmission components are very weak, the torque is small, the chain transmission is loud, the maintenance rate is high, and it is unsafe. Machinery without self-protection design can damage the surface of the roller, even deform, and pull the roller when the bearing capacity is too high or foreign objects enter. Maximum roller distance: 12mm

Lina: The transmission part has high torque, low noise, and long service life. When the load is too large or hard objects enter, the safety plate will automatically disconnect, pulling apart the distance between the two rollers and minimizing surface damage to the rollers. Maximum roller distance: 16mm

Silicone open mill configuration

Main motor: Datong/Dongyuan/Siemens, etc. (Taiwanese or international brands, depending on delivery time and supplier inventory), installation size and power rating fully comply with IEC standards. Adopting B-grade insulation, the shell protection level is IP44, and the cooling method is IC411

Reducer: Guomao four ring or three ring hard tooth surface reducer, customized with Guomao Group, widened and thickened helical hard tooth grinding surface. Compared to ordinary brand reducers, it can save more than 1/4. Each gear undergoes heat treatment and grinding to reduce friction losses during operation. The same load in different directions cannot be achieved by traditional gearboxes. The gearbox is equipped with a cooling circulation system, which has low noise, high transmission power, and can withstand higher loads. The overall body of the gearbox is designed to be leak proof and safe.

Gearbox: Made of advanced chrome and special steel, precision machined by advanced units imported from West Germany, high accuracy, excellent assembly quality, not easily worn or broken, achieving optimal transmission efficiency, low noise, extremely low failure rate, and energy-saving

Belt pulley assembly: Both the main motor and the gearbox drive belt pulley have increased diameters, increasing the power of the motorcycle. Adopting a modern design, it is not easy to slip off and is easy to replace.

Transmission mode: Single axis output ensures high torque, imported bearings reduce rubbing force to ensure power saving, low noise, and even and controllable rubber thickness. The transmission link is a lotus style specialized coupling, which has the functions of compensating for the relative offset of the two shafts, shock absorption, wear resistance, and buffering performance, ensuring the safety and durability of the transmission components. Ensure smooth operation of machinery, low maintenance rate, and improve work efficiency.

Low voltage electrical appliances: Omron/Schneider, etc. (electrical components are 100% imported).

Bearing: Adopting the international brand SKF from Sweden, with small clearance and less risk of roller jumping, ensuring uniform sheet output. Wear resistant, low-noise, and extend the service life of machinery.

Cooling device: Adopting fully enclosed cooling and heating, the advantage is that the cooling and heating are in place and the pollution of the circulating water source is protected or reduced.
