Technical Field

[0001] The utility model relates to the field of silica gel refining, in particular to a constant temperature rust-proof silica gel refining machine. Background Art

[0002] The silicone mixing mill is a kind of plastic mixing equipment used by plastic product manufacturers. At present, the silicone mixing mill mainly includes a roller and a position adjustment block, and secondly includes a pneumatic push rod. The specific process is to place the raw materials in the gap between the two rollers. Through the rotation of the rollers, the raw materials are repeatedly crushed, and the staff processes the raw materials.

[0003] A Chinese patent discloses a constant temperature and rust-proof silicone open mill (authorization announcement number CN 220498948 U). This patented technology can solve the problem that the existing silicone open mill has an incomplete structural design, which leads to the need for workers to repeatedly crush the raw materials during use. When working, the raw materials are insufficient and need to be added. The existing technology cannot control the feeding speed during automatic feeding, and when adding more raw materials, it will consume a lot of time.

[0004] However, when the existing silica gel mixing mill drum rotates at a high speed, its connection is easily heated due to friction, thereby reducing the service life of the device, and if the raw materials splash out during rotation, it is easy to cause harm to the surrounding personnel. Summary of the invention

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In this embodiment, a constant temperature and rust-proof silicone open mill is provided, including a base 1 and an open mill body 2. The upper end surface of the base 1 is arranged with the open mill body 2, and the upper end surface of the base 1 is provided with a fixing groove, and an adjusting screw 11 is rotatably installed on the left end surface of the fixing groove through a bearing, and an adjusting motor 12 is installed on the right end surface of the adjusting screw 11. An adjusting slider is symmetrically screwed on the outer wall of the adjusting screw 11, and a protective cavity 13 is installed on the upper end surface of the adjusting slider, and a fixed fan 14 is installed on the upper end surface of the protective cavity 13. An annular sleeve 15 is installed at the bottom of the fixed fan 14, and a plurality of air outlet holes 16 are opened at the bottom of the annular sleeve 15. The outer end of the protective cavity 13 is provided with an air vent 2 4. When the mixing mill body 2 is working, it drives the roller to rotate at high speed to mix and refine the rubber. During the high-speed rotation of the roller, the friction may easily lead to excessive temperature, which shortens the service life of the roller and requires frequent replacement. The adjusting motor 12 is started to drive the adjusting screw 11 to rotate and drive the protective cavity 13 to move inward, thereby sealing and protecting the mixing mill body 2 to avoid rusting of the equipment due to the influence of external humidity for a long time and effectively avoiding accidental splashing of raw materials during high-speed rotation to cause damage to the human body. The fixed fan 14 is started, and the cold air passes through the annular sleeve 15 and is then discharged through the air outlet 16 to cool the surface of the roller.

[0022] A cushion 17 is installed at the bottom of the base 1. The cushion 17 is made of elastic material. When the mixing mill body 2 is working, it is easy to cause the ground to crack due to vibration. The cushion 17 structure is used to provide shock-absorbing protection for the ground.

[0023] An L-shaped frame 18 is installed at the outer end of the protective cavity 13, and a square groove is opened on the upper end surface of the L-shaped frame 18. A limit spring 19 is installed at the inner and outer ends of the square groove, and a limit slider is installed at the other end of the limit spring 19. A plug rod 21 is installed on the upper end surface of the limit slider. The plug rod 21 is arranged in the air vent 24. When working, when the fixed fan 14 is working, when the cold wind cools the open mill body 2, the cold wind will open the plug rod 21, so that the cold wind is discharged through the air vent 24, and the limit spring 19 plays a role in resetting the plug rod 21.

[0024] The upper end surface of the base 1 is symmetrically equipped with bottom columns 22, which are connected to the bottom of the mixing mill body 2 by plugging. When working, the bottom columns 22 play a positioning role for the mixing mill body 2 to prevent the mixing mill body 2 from vibrating during operation and causing the device to deviate.

[0025] The fixed fan 14 is connected to the annular sleeve 15 by screw thread rotation. When the fan is in operation, the annular sleeve 15 can be disassembled and cleaned by screw thread rotation.

[0026] The upper end face of the protective cavity 13 is provided with insertion holes at the front and rear, and L-shaped plates 23 are arranged in the insertion holes. The L-shaped plates 23 are arranged at the front and rear sides of the annular sleeve 15. When working, the L-shaped plates 23 limit and fix the front and rear sides of the annular sleeve 15 to ensure the stability of the annular sleeve 15 and prevent the connection of the annular sleeve 15 from loosening.

[0027] During specific operation, when the mixing mill body 2 is working, the mixing rubber is mixed by driving the roller to rotate at high speed. During the high-speed rotation of the roller, the temperature is easily too high due to friction, which shortens the service life of the roller and requires frequent replacement. The adjusting motor 12 is started to drive the adjusting screw 11 to rotate, and the protective cavity 13 is driven to move inward, so as to seal and protect the mixing mill body 2 to avoid rusting of the equipment due to the influence of external humidity for a long time, and effectively avoid accidental splashing of raw materials during high-speed rotation to cause damage to the human body. The fixed fan 14 is started, and the cold air passes through the annular sleeve 15 and is then discharged through the air outlet 16 to cool the surface of the roller.

[0028] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
