[0023] The utility model provides a material mixing device. Figure 1 The utility model provides a specific embodiment of a material mixing equipment.

[0024] like Figure 1 As shown, an embodiment of the utility model provides a mixing device 100, including a mixing trough 1 and a stirring device 2, wherein the mixing trough 1 has a stirring chamber with an opening at the top, and the stirring device 2 includes a stirring part 21 and a heating part 22, wherein the stirring part 21 is rotatably arranged in the stirring chamber, and the heating part 22 is arranged at the bottom of the mixing trough 1 and is located outside the stirring chamber.

[0025] In the present invention, the mixing tank 1 has a stirring chamber with an opening at the top, and the rubber is input into the stirring chamber from the opening. Since the stirring part 21 is rotatably arranged in the stirring chamber, the stirring part 21 can stir the rubber in the stirring chamber all the time, so as to avoid the stratification and sedimentation of the rubber, which leads to uneven viscosity of the rubber and affects the quality of the final product. At the same time, the optimal temperature required for the rubber is different in different seasons. In order to ensure the quality of the product, a heating part 22 is provided at the bottom of the mixing tank 1, and the mixing tank 1 is heated by the heating part 22, so as to increase the temperature of the rubber. The mixing equipment 100 provided by the present invention can realize the uniform distribution and temperature control of the stirred rubber, so as to ensure the stable quality of the product.

[0026] It should be noted that the mixing equipment 100 also includes a temperature sensor and a controller. The temperature sensor is arranged in the mixing chamber to detect the temperature of the rubber. The temperature sensor and the heating unit 22 are both electrically connected to the controller. The temperature sensor transmits the detected temperature of the rubber to the controller. The controller controls the switch and power adjustment of the heating unit 22 according to the acquired temperature information of the rubber, so that the rubber in the mixing tank 1 is kept within a constant temperature range. For example, in the actual production process, the temperature of the rubber needs to be kept at about 38 degrees in summer and at about 42 degrees in winter. The temperature of the rubber is negatively feedback-regulated by the controller. When the detected temperature is higher than the preset temperature, the controller controls the heating unit 22 to stop running or reduce the output power. When the detected temperature is lower than the preset temperature, the heating unit 22 is controlled to start or increase the output power.

[0027] Specifically, Figure 1 As shown, the mixing equipment 100 also includes a display device 8, which is electrically connected to the controller. The display device 8 can display the current temperature information and preset temperature information of the rubber material, and the operator can adjust the preset temperature through the button on the display device 8.

[0028] In some embodiments, the heating part 22 includes a coil, and the coil generates a rotating magnetic field after current is passed through it. The stirring part 21 is located in the rotating magnetic field, and the stirring part 21 is made of magnetic material. In this way, the driving function is realized by the heating part 22, the components driving the stirring part 21 are reduced, and the production cost and assembly cost are reduced. Specifically, the heating part 22 can be an electromagnetic generator. According to the principle of electromagnetic induction heating, the electromagnetic generator can generate an alternating magnetic field. The mixing tank 1 is made of metal. The magnetic lines of force of the alternating magnetic field pass through the mixing tank 1 made of metal material, and a large number of eddy currents are generated at the bottom of the tank, thereby heating the mixing tank 1 and increasing the temperature of the rubber. At the same time, the stirring part 21 is made of magnetic material. According to the principle of electromagnetic rotation, the rotating magnetic field generated by the coil in the electromagnetic generator can drive the stirring part 21 to rotate.

[0029] It should be noted that the heating part 22 includes but is not limited to a magnetic stirring electric heating mantle, and other components known to those skilled in the art that can simultaneously realize heating and magnetic driving functions.

[0030] The number of the heating part 22 and the stirring part 21 is not limited, as long as the heating part 22 can heat the mixing tank 1 and drive the stirring part 21 to rotate. For example, in some embodiments, Figure 1 As shown, the heating part 22 and the stirring part 21 are both provided in plurality, and the plurality of heating parts 22 are arranged at intervals along the length direction of the mixing tank 1, and each stirring part 21 is arranged in one-to-one correspondence with the heating part 22. The plurality of stirring parts 21 can stir the rubber in the mixing tank 1 more evenly, and the plurality of heating parts 22 can improve the temperature raising efficiency of the rubber on the one hand, and can evenly heat the rubber at each position in the mixing tank 1 on the other hand, so as to avoid different temperatures of the rubber at different positions, resulting in different viscosity of the rubber, and affecting the quality of the final product. At the same time, the number and position of the heating part 22 correspond to the number and position of the stirring part 21 in one-to-one correspondence.

[0031] Since the glue needs to be input into the mixing tank 1 before mixing, and there are other production equipment in the production site, in order to prevent foreign matter from entering the mixing equipment 100 and affecting the normal operation of various components, in some embodiments, such as Figure 1 As shown, the mixing device 100 further includes a housing 3, and the mixing tank 1 and the stirring device 2 are both arranged in the housing 3. With such arrangement, on the one hand, the housing 3 can protect the various components of the mixing device 100 and prevent foreign matter from entering therein to affect the operation of the components. On the other hand, by arranging all the components in the housing 3, the mixing device 100 can be easily moved, so that the mixing device 100 can be applied to more places.

[0032] After the glue in the mixing tank 1 is stirred, the roller is extended into the mixing chamber to dip in the glue. As the glue gradually decreases, the height of the glue in the mixing tank 1 gradually decreases, making it difficult for the roller to be fully dipped in the glue, affecting the gluing effect. If the roller is controlled to move downward, the transmission component of the roller may collide with the housing 3. Therefore, in some embodiments, Figure 1 As shown, the mixing device 100 further includes a lifting part 4 and a connecting seat 5. The lifting part 4 is arranged in the shell 3, and extends along the height direction of the shell 3, and has a movable stroke in the height direction of the shell 3. One end of the connecting seat 5 is connected to the lifting part 4, and the other end is connected to the mixing tank 1. In this way, when the height of the glue material is reduced, the lifting part 4 rises, driving the mixing tank 1 to move upward to restore the height of the glue material, ensuring that the roller is fully dipped in glue, thereby ensuring the quality of the product after gluing.

[0033] Specifically, the lifting part 4 can be a spiral lifting rod, an electric push rod, a telescopic sleeve rod or other components with lifting functions known to those skilled in the art.

[0034] When one lifting part 4 is provided, the connecting seat 5 and the mixing tank 1 are both supported by the lifting part 4. When the lifting part 4 is lifted or lowered, the support is easily unstable. Therefore, in some embodiments, as shown in FIG. Figure 1 As shown, the lifting parts 4 are provided in plurality, and the plurality of lifting parts 4 are arranged along the length direction of the connecting seat 5. In this arrangement, the connecting seat 5 and the mixing tank 1 are supported together by the plurality of lifting parts 4, so that the support stability can be improved.

[0035] When the lifting part 4 rises, the mixing tank 1 can be driven to move upward. In order to prevent the mixing tank 1 from moving upward and separating from the shell 3, causing foreign matter to enter the shell 3, in some embodiments, Figure 1 As shown, the mixing device 100 further includes a limiting device 6 for limiting the mixing tank 1 from being separated from the housing 3, and the limiting device 6 is arranged at an end of the housing 3 close to one end of the mixing tank 1. The limiting device 6 can be a limiting block, which directly limits the upward movement of the mixing tank 1, has a simple structure, and has a very low production cost.

[0036] Preferably, the limiting device 6 can also be a photoelectric sensor, and the photoelectric sensor and the driving device of the lifting part 4 are electrically connected to the controller. When it is detected that the mixing trough 1 is close to the port of the shell 3, the signal is transmitted to the controller, and the controller controls the driving device to stop running, thereby stopping the mixing trough 1 from moving upward.

[0037] It should be noted that the limiting device 6 may also be other components known to those skilled in the art that can limit the movement of the mixing tank 1 .

[0038] The operator can observe the reduction of the glue in the mixing tank 1 with the naked eye, and then press the control button on the display screen to control the lifting part 4 to rise, thereby driving the mixing tank 1 to rise. The equipment can also automatically recognize the reduction of the glue in the mixing tank 1 and control the lifting part 4 to rise. Therefore, in some embodiments, Figure 1 As shown, the mixing equipment 100 further includes a weighing device 7, one end of which is connected to the connecting seat 5, and the other end is connected to the mixing tank 1. With such a configuration, the mass of the mixing tank 1 can be obtained in real time through the weighing device 7, and the reduction of the rubber material can be judged by the change in mass, thereby controlling the lifting part 4 to rise, thereby driving the mixing tank 1 to rise. The weighing device 7 and the display device 8 are electrically connected to the controller, and the display device 8 displays the mass obtained by the weighing device 7 in real time. The operator can decide whether to add material according to the change in mass displayed by the display device 8.

[0039] As the roller dips into the glue in the mixing tank 1, the glue gradually decreases, and the roller needs to contact the bottom of the mixing tank 1 to dip into the remaining glue, which will interfere with the stirring part 21. In order to avoid this situation, in some embodiments, Figure 1 As shown, a receiving groove 11 is provided at the bottom of the mixing tank 1 for the stirring part 21 to be rotatably arranged. The depth of the receiving groove 11 is greater than the thickness of the stirring part 21. In this way, even if the roller contacts the bottom of the mixing tank 1, it will not interfere with the stirring part 21 and affect the movement of the stirring part 21.

[0040] Specifically, the bottom cross-section of the receiving groove 11 is circular, and the diameter of the bottom is slightly larger than the length of the stirring portion 21. On the one hand, the stirring portion 21 can be rotatably arranged in the receiving groove 11, and on the other hand, excessive rubber material is prevented from entering the receiving groove 11 to cause waste.

[0041] In order to allow the roller to soak up the glue in the mixing tank 1 as much as possible, the length of the roller is slightly smaller than the length of the mixing tank 1. When the roller contacts the bottom of the tank, the axis of the roller may collide with the inner wall of the mixing tank 1. Therefore, in some embodiments, Figure 1As shown, the circumferential side of the mixing tank 1 is inclined from the notch position toward the direction close to the middle of the tank bottom. In this way, even if the roller contacts the tank bottom, the axis of the roller will not collide with the inner wall of the mixing tank 1, and it can also ensure that the rubber remaining on the inner wall of the mixing tank 1 can flow to the tank bottom under the action of gravity.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
