Description

Technical Field

[0001] The invention relates to the technical field of open mixing mills, in particular to an intelligent temperature-controlled rubber mixing mill for producing rubber masterbatches. Background Art

[0002] The open mill is the abbreviation of the open plastic refining machine. In plastic product factories, people are used to calling it a two-roller mill. The open mill is a kind of plastic mixing equipment that was used earlier in plastic product manufacturers. On the calender production line, the open mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniformly mixed and plasticized molten material for the calender to calender and mold plastic products. When producing cable materials, the open mill can directly refine and plasticize the powdered materials mixed according to the formula into molten materials, and then press them into sheet strips, so that the pelletizer can cut them into granules.

[0024] (II) Beneficial effects

[0025] The present invention provides an intelligent temperature-controlled rubber mixer for rubber masterbatch production, which has the following beneficial effects:

[0026] The present invention sets the parameters for rubber mixing through the control panel, and at the same time inputs a heat-conducting liquid of a certain temperature into the temperature control mechanism through the mold temperature controller. After the heat-conducting liquid enters the conveying cavity, it will enter the heat exchange groove. At the same time, the heat-conducting plate absorbs heat and heats up. After the heat-conducting plate absorbs heat, the temperature will gradually tend to be consistent with the heat-conducting liquid. The heating roller and the heat-conducting plate heat the roller at the same time, so that the roller is more stable when heated.

[0027] At the same time, after the heat transfer liquid is introduced through the delivery pipe, the heat loss in the conveying cavity is extremely small. At the same time, after entering the connecting groove, the flow rate of the heat transfer liquid increases, which prevents the heat transfer liquid from taking too long to transfer heat, thereby causing a large temperature difference at both ends along the flow direction of the liquid, thereby improving the accuracy of temperature control of the roller;

[0028] It is also equipped with an intelligent temperature control system, which takes multi-point samples on the roller surface and inside the heat exchange tank, processes the temperature value of each sample, minimizes the impact of abnormal measurement data on the control effect, and uses real-time temperature analysis to calculate the temperature control amount at the next moment, thereby achieving precise and stable control of the rubber mixing temperature and greatly improving the timeliness of temperature control.

[0043] like Figure 1-7 As shown, this embodiment provides an intelligent temperature-controlled rubber mixer for rubber masterbatch production, including a frame 100 and a mold temperature controller 600. Two groups of support frames 500 are arranged on the upper end surface of the frame 100, and a temperature control mechanism is arranged between the two groups of support frames 500. The temperature control mechanism includes two groups of rollers 400 arranged in parallel. A mounting seat 200 is fixedly connected to one side of the upper end surface of the frame 100, and a power mechanism is arranged on the upper end surface of the mounting seat 200. The power mechanism is used to drive the rollers 400 to rotate, and a control panel 300 is arranged on the front end surface of the mounting seat 200.

[0044] A temperature sensor 401 is installed at one end of the roller 400, a heating roller 402 is arranged inside the roller 400, a mounting ring 403 is arranged at one end of the heating roller 402 away from the roller 400, a plurality of groups of heat conducting plates 407 are fixedly connected to the outside of the heating roller 402, heat exchange grooves 406 are provided between the plurality of groups of heat conducting plates 407, a conveying cavity 405 is provided inside the heating roller 402, a conveying pipe 410 and a return pipe 411 are fixedly connected at one end of the mounting ring 403, and the return pipe 411 is provided outside the conveying pipe 410;

[0045] The input port of the mold temperature controller 600 is connected to the reflux pipe 411 , and the output port of the mold temperature controller 600 is connected to the delivery pipe 410 . The mold temperature controller 600 is used to transmit the heat-conducting liquid and adjust the temperature of the heat-conducting liquid.

[0046] Among them, the power mechanism includes a driving motor 201 and a transmission gear box 202. A gear set is arranged inside the transmission gear box 202. The output shaft of the driving motor 201 drives the gear set to rotate. The output gear in the gear set transmits power to the roller 400 through the rotating shaft. The gear set inside the transmission gear box 202 and the method of transmitting power by the gear set belong to the prior art and will not be described in detail here.

[0047] Specifically, the rubber raw materials will be refined between two groups of rollers 400. Some parameters required for the raw materials in the refining process can be adjusted through the control panel 300. During the rubber refining process, a heat-conducting liquid of a certain temperature is input into the temperature control mechanism through the mold temperature controller 600. After the heat-conducting liquid enters the conveying cavity 405, it will enter the heat exchange groove 406. At the same time, the heat conduction plate 407 absorbs heat and heats up, so that the external temperature of the heating roller 402 increases, thereby increasing the external temperature of the roller 400.

[0048] After absorbing heat, the temperature of the heat conducting plate 407 gradually tends to be consistent with that of the heat conducting liquid. The heating roller 402 and the heat conducting plate 407 heat the roller 400 at the same time, so that the roller 400 is more stable when heated.

[0049] Furthermore, a heat insulating layer 404 is disposed inside the heating roller 402 . The heat insulating layer 404 is disposed between the conveying cavity 405 and the heat conducting plate 407 , and the heat insulating layer 404 does not contact the conveying cavity 405 and the heat conducting plate 407 .

[0050] Specifically, the heat insulating layer 404 can isolate the temperature transfer of the heat-conducting liquid in the delivery cavity 405 , thereby preventing the influence of heat transfer on the temperature of the heat-conducting liquid in the heat exchange groove 406 .

[0051] Furthermore, a plurality of groups of communication grooves 409 are formed at the other end of the mounting ring 403 , and the plurality of groups of communication grooves 409 are connected to the plurality of groups of heat exchange grooves 406 .

[0052] Furthermore, a reflux groove 408 is provided inside the mounting ring 403 , and the reflux pipe 411 is connected to a plurality of groups of communication grooves 409 via 428 .

[0053] Furthermore, the delivery tube 410 is connected to the delivery cavity 405 , and the total cross-sectional area of ​​the plurality of groups of communication grooves 409 is smaller than the cross-sectional area of ​​the delivery tube 410 .

[0054] Specifically, after the heat-conducting liquid is introduced through the delivery pipe 410, the heat loss in the internal process of the delivery chamber 405 is extremely small. At the same time, after entering the connecting groove 409, the flow rate of the heat-conducting liquid increases, which prevents the heat-conducting liquid from transferring heat for too long, thereby causing excessive temperature difference at both ends along the liquid flow direction, thereby improving the accuracy of temperature control of the roller 400.

[0055] Furthermore, the intelligent temperature control rubber mixing machine also includes an intelligent temperature control system, which includes:

[0056] An acquisition module is used to acquire the temperature of the heat-conducting liquid output by the mold temperature controller 600 of the rubber mixing machine at the current moment, the surface temperature of the plurality of rollers 400 and the internal temperature of the plurality of heat exchange grooves 406, and to acquire the target temperature value of the rubber mixing machine at the current moment;

[0057] A data processing module, used to process the acquired surface temperatures of the plurality of rollers 400 and the internal temperatures of the plurality of heat exchange grooves 406 to obtain a feedback temperature value;

[0058] An analysis module is used to analyze the target temperature value of the rubber compound at the current moment and the feedback temperature value of the surface temperature of the roller 400 to obtain a temperature difference value;

[0059] The calculation control module is used to input the temperature difference into a pre-built transfer function to obtain the temperature control amount of the heat transfer liquid at the next moment, and control the temperature of the heat transfer liquid output by the mold temperature controller 600 based on the temperature control amount.

[0060] Furthermore, the surface temperatures of the multiple rollers 400 are collected from multiple points on the surface of the rollers 400 at the same time, and the internal temperatures of the multiple heat exchange grooves 406 are collected from multiple points inside the heat exchange grooves 406 at the same time.

[0061] In this embodiment, multiple measuring points are pre-set on the surface of the roller 400 and inside the heat exchange tank 406, and temperature is collected at the same time by setting a temperature sensor 401 at each measuring point; the target temperature value is specifically the preset temperature when the rubber mixing program is set through the control panel 300.

[0062] The measuring points on the surface of the roller 400 and inside the heat exchange groove 406 are evenly distributed along the axial direction.

[0063] Furthermore, the obtained surface temperatures of the plurality of rollers 400 and the internal temperatures of the plurality of heat exchange grooves 406 are processed to obtain feedback temperature values ​​including:

[0064] The surface temperatures of multiple rollers 400 and the internal temperatures of multiple heat exchange grooves 406 are added and averaged to obtain the feedback temperature values ​​of the roller 400 surface and the heat exchange groove 406 respectively. There is a corresponding relationship between the feedback temperature value of the roller 400 surface and the feedback temperature value of the heat exchange groove 406.

[0065] Specifically, the temperature sensor can collect multiple temperature values ​​at the same time. During the processing, for the multiple temperature values ​​collected at the same time, the median value is taken. For an even number, the average of the two middle temperature values ​​is taken as the temperature value to obtain the temperature value of the measurement point.

[0066] Furthermore, the transfer function includes:

[0067]

[0068] Among them, U(s) represents, s represents the complex variable in Laplace transform, K represents the transfer gain coefficient, T represents the time constant, E(s) represents the temperature difference, λ represents the adjustable parameter, e represents the natural constant, and τ represents the lag time of the mold temperature controller.

[0069] Based on the above-mentioned intelligent temperature control rubber mixer and intelligent temperature control system, this embodiment also provides an intelligent temperature control method: comprising:

[0070] Setting the rubber mixing program through the control panel 300;

[0071] Obtain the temperature of the heat transfer liquid output by the mold temperature controller 600 of the rubber mixing machine at the current moment, the surface temperature of the plurality of rollers 400 and the internal temperature of the plurality of heat exchange grooves 406, and obtain the target temperature value of the rubber mixing machine at the current moment;

[0072] Processing the obtained surface temperatures of the plurality of rollers 400 and the internal temperatures of the plurality of heat exchange grooves 406 to obtain feedback temperature values;

[0073] The target temperature value of the rubber compound at the current moment and the feedback temperature value of the roller 400 surface temperature are analyzed to obtain the temperature difference value;

[0074] The temperature difference is input into a pre-constructed transfer function to obtain the temperature control amount of the heat transfer liquid at the next moment, and the temperature of the heat transfer liquid output by the mold temperature controller 600 is controlled based on the temperature control amount.

[0075] The intelligent temperature-controlled rubber mixer for rubber masterbatch production provided by the present invention: the parameters for rubber mixing are set through the control panel 300, and a heat-conducting liquid of a certain temperature is input into the temperature control mechanism through the mold temperature controller 600. After the heat-conducting liquid enters the conveying cavity 405, it will enter the heat exchange groove 406. At the same time, the heat-conducting plate 407 absorbs heat and heats up. After the heat-conducting plate 407 absorbs heat, the temperature will gradually tend to be consistent with the heat-conducting liquid. The heating roller 402 and the heat-conducting plate 407 heat the roller 400 at the same time, so that the roller 400 is more stable when heated.

[0076] At the same time, after the heat-conducting liquid is introduced through the delivery pipe 410, the heat loss in the delivery chamber 405 is extremely small. At the same time, after entering the connecting groove 409, the flow rate of the heat-conducting liquid increases, which prevents the heat-conducting liquid from transferring heat for too long, thereby causing a large temperature difference at both ends along the liquid flow direction, thereby improving the accuracy of temperature control of the roller 400;

[0077] In addition, an intelligent temperature control system is provided to perform multi-point sampling on the surface of the roller 400 and the inside of the heat exchange tank 406, and process the temperature value of each sample to minimize the influence of abnormal measurement data on the control effect. In addition, the temperature control amount at the next moment is calculated by using real-time temperature analysis, thereby achieving precise and stable control of the rubber mixing temperature and greatly improving the timeliness of temperature control.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
