In order to achieve the above object, the utility model provides a following technical scheme:
the open mill with the controllable temperature comprises a support and two parallel roller modules, wherein each roller module comprises a compression roller, a supporting cylinder made of metal and a driving module used for driving the compression roller to rotate; the outside of a supporting cylinder is provided with an electric heating strip and a temperature sensor, the outside of the support is provided with a main control board, and the electric heating strip, the temperature sensor and the liquid pump are electrically connected with the main control board.
Preferably, an insulating and heat-insulating pad is arranged between the support and the support cylinder.
The utility model has the advantages that:
during the use, mill initial start-up stage, the electricity is circular telegram earlier to the electric heat strip, to supporting a section of thick bamboo heating, and the heat of supporting a section of thick bamboo passes through bearing and air transfer to the compression roller, preheats the compression roller, and temperature sensor senses the temperature of supporting a section of thick bamboo and reaches the temperature of predetermineeing after, and main control board control electric heat strip cuts off the power supply. The raw materials are pressed through the gap between two compression rollers of two roller modules, the compression rollers are rubbed by rubber to rise the temperature continuously, the liquid pump is started after the temperature detected by the temperature sensor reaches another threshold value, so that the cooling channel in the supporting cylinder circulates and removes water, the deionized water absorbs heat, the compression rollers and the supporting cylinder are cooled, and the aim of controlling the overhigh temperature of the compression rollers is fulfilled. Compared with the prior art, the utility model discloses a controllable mill of temperature, the temperature that can control the compression roller is in the certain limit, and avoids the too high influence rubber suppression quality of compression roller temperature.

Detailed Description
The present invention will be described in detail with reference to the following embodiments and accompanying drawings.
The controllable mill of temperature of this embodiment, as shown in fig. 1, including support 1 and roller module, the roller module has two that the structure is the same side by side, and every roller module includes that a support section of thick bamboo 3 of compression roller 2, metal material and be used for driving a drive module 5 that 2 pivoted of compression roller are rotated, and support section of thick bamboo 3's both ends are fixed in support 1, are provided with insulating heat insulating mattress 6 between support 1 and the support section of thick bamboo 3. The two ends of the press roller 2 are rotatably arranged on the outer side of the supporting cylinder 3 through bearings 12, a circuitous cooling channel 4 is formed in the supporting cylinder 3, a liquid inlet end of the cooling channel 4 is connected with a liquid pump 7 through a hose, a liquid outlet end of the cooling channel 4 is connected with a water tank 8 through a hose, the water tank 8 is loaded with non-conductive deionized water, the deionized water refers to pure water with impurities in an ion form removed, soluble organic matters still exist in the water and exist in a molecular form, the deionized water does not have ions capable of moving freely, and the molecules are electrically neutral, so that the deionized water is non-conductive. The liquid pump 7 is connected to the water tank 8 by a hose. The outside of a supporting cylinder 3 is provided with an electric heating strip 9 and a temperature sensor 10, the electric heating strip 9 penetrates from the middle of the supporting cylinder 3, penetrates out of a hole formed in the side wall of the electric heating strip and winds on the outside of the supporting cylinder 3, a main control board 11 is arranged on the outside of the support 1, and the electric heating strip 9, the temperature sensor 10 and the liquid pump 7 are electrically connected with the main control board 11.
During the use, the mill initial start-up stage, electricity is first switched on to the electrothermal strip 9, to supporting a section of thick bamboo 3 heating, the heat of supporting a section of thick bamboo 3 transmits compression roller 2 through bearing 12 and air transmission, preheats compression roller 2, temperature sensor 10 senses after the temperature of supporting a section of thick bamboo 3 reaches preset temperature (ideal temperature is that the temperature of compression roller 2 reaches 40 ℃, but because temperature sensor 10 can't directly detect the temperature of compression roller 2, but detects supporting a section of thick bamboo 3 temperature, so can suitably adjust this preset temperature and be 45 ~ 50 ℃), main control board 11 control electricity 9 outage. Then the raw materials are pressed through a gap between two compression rollers 2 of two roller modules, the temperature of the compression rollers 2 is continuously increased due to friction of the rubber raw materials, when the temperature detected by the temperature sensor 10 reaches another threshold value (the ideal temperature is 100 ℃, the temperature of the compression rollers 2 cannot be directly detected in the same way, and therefore the threshold value can be properly adjusted to be 85-90 ℃), the main control board 11 starts the liquid pump 7, so that water is removed through circulation in a cooling channel 4 in the supporting cylinder 3 in the direction of an arrow of a dotted line, the heat of the compression rollers 2 is transferred to the side walls of the supporting cylinder 3 through the bearing 12 and air, the deionized water absorbs the heat of the side walls of the supporting cylinder 3, the compression rollers 2 and the supporting cylinder 3 are cooled, and the purpose of controlling the temperature of the compression rollers 2. When the temperature detected by the temperature sensor 10 is lower than the threshold value, the main control board 11 controls the liquid pump 7 to stop working, and the process is circulated. Compared with the prior art, the utility model discloses a controllable mill of temperature, the temperature that can control compression roller 2 is at the certain limit, and avoids 2 high temperatures of compression roller to influence the rubber suppression quality.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
