Description

Technical Field

[0002] Automobile tires are one of the important parts of an automobile. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the car when it is driving, ensuring that the car has good ride comfort and driving smoothness; ensuring good adhesion between the wheels and the road surface; improving the car's traction, braking and passability; and bearing the weight of the car. The important role that tires play in automobiles is increasingly being valued by people.

[0003] Tire rubber for automobile tires is refined in an internal mixer. Specifically, raw materials such as carbon black, natural / synthetic rubber, oil, additives, accelerators, etc. are mixed together and mixed in the mixing chamber of the internal mixer under the interaction of the rotor and the pressure weight to produce tire rubber.

[0004] In the current prior art, a temperature-adjustable internal mixer for tire production proposed in application number CN202321107200.8 solves the hand scratch phenomenon caused by manually taking out the tire rubber by using the transmission parts of the gear and rack, but has high requirements for the gear and rack. If there is an error in the transmission ratio of the two or after subsequent wear, the gear and rack cannot continue to transmit or transmit slowly, and the subsequent maintenance cost is also high.

[0005] Furthermore, in the prior art, when a heating device inside the chassis fails and its temperature gradually increases, there is an emergency measure to cut off the power supply to the heating device to protect the internal temperature from continuing to rise. For this reason, this scheme proposes a temperature-adjustable internal mixer for tire production. Utility Model Content

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", "provided on" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0030] See also Figure 1-3A temperature-adjustable internal mixer for tire production comprises a chassis 1, a base 2 is fixedly connected to the lower end of the chassis 1, a sealing door plate is rotatably connected to the front end of the chassis 1, a rotor 3 and a rotor 4 are respectively installed on the lower side of the interior of the chassis 1, the rotor 1 3 and the rotor 2 4 are rotatably connected to the inner wall of the chassis 1 through a rotating rod, and are symmetrically distributed left and right, two connecting brackets 5 symmetrically distributed up and down are slidably connected between the inner walls of the chassis 1, a pressure weight 6 is installed at the lower end of the connecting bracket 5 on the upper side, and a material placing plate 7 is installed at the upper end of the connecting bracket 5 on the lower side, a transmission assembly 8 is installed between the connecting bracket 5 and the inner wall of the chassis 1, a heater 10 and an emergency power-off assembly 11 are installed on the inner wall of the chassis 1, the heater 10 is located on the left and right sides of the rotor 1 3 and the rotor 2 4, and the emergency power-off assembly 11 is located on the upper side of the heater 10.

[0031] During use, in order to avoid the wear of the gears and racks in the prior art after long-term use, resulting in inability to use and requiring high-cost maintenance, and to avoid the phenomenon that the temperature of the existing heating device still rises sharply when a fault occurs, in this embodiment, by adopting a synchronous transmission mode of a bidirectional threaded screw, the material placement plate 7 and the pressure weight 6 loaded with tire rubber can be synchronously located on the upper and lower sides of the rotor 1 3 and the rotor 2 4, and then the rubber mixing work is carried out under the action of the heater 10, so that the transmission of the tire rubber in the rubber mixing work is more stable, and there is no need to worry about the phenomenon that the wear of the gears and racks causes the transmission to fail and requires high-cost maintenance in the prior art;

[0032] At the same time, during the rubber mixing process, if the temperature is high and reaches a certain critical point, in this embodiment, the emergency power-off component 11 can be used to timely cut off the power supply to the heater 10, so that the heater 10 can no longer continue to heat, thereby avoiding the occurrence of safety hazards caused by excessive temperature rise inside the chassis;

[0033] When in use, the personnel opens the sealed door panel on the outside of the chassis 1, places the tire rubber material to be processed on the top of the material placement plate 7, and then drives the transmission component 8 to cause the pressure weight 6 and the material placement plate 7 to move synchronously and relatively toward the side of the rotor 1 3 and the rotor 2 4, and starts the heater 10 synchronously to cause the tire rubber material to be refined. During the processing, due to the setting of the emergency power-off component 11, when the temperature heated by the heater 10 inside the chassis 1 exceeds the required critical point, that is, when a fault occurs, the emergency power-off component 11 can cut off the power to the heater 10, so that the temperature inside the chassis 1 no longer increases, thereby reducing the safety hazard of the tire rubber material during processing.

[0034] See also Figure 1-2The transmission assembly 8 includes a transmission frame 81 fixedly connected to the side wall of the chassis 1, and two symmetrical limit plates 82 are fixedly connected to the central end on the inner wall of the transmission frame 81. A bidirectional threaded rod 83 is movably installed between the upper and lower inner walls of the transmission frame 81. The lower side end of the bidirectional threaded rod 83 is a right-handed screw thread setting, and the upper side end is a left-handed screw thread setting. The screw threads at both ends of the bidirectional threaded rod 83 are respectively sleeved with sliders 84, and the outer end of the slider 84 is fixedly connected to a connecting plate 85, and the connecting plate 85 is fixedly connected to one end of the connecting bracket 5.

[0035] More specifically, the top of the bidirectional threaded rod 83 penetrates to the upper side of the transmission frame 81 , a motor 9 is installed on the top of the chassis 1 , and the output end of the motor 9 is fixedly connected to the top of the bidirectional threaded rod 83 .

[0036] During the use of this solution, when it is necessary to feed the tire rubber material, the personnel drive the motor 9 to cause the bidirectional threaded rod 83 to rotate, and the bidirectional threaded rod 83 is a left-handed screw rod, and the main structure is that one end is a left-handed screw thread, and the other side is a right-handed screw thread, just like the structure when two nuts on a rod can realize simultaneous movement in opposite directions, the lower side of the bidirectional threaded rod 83 is a right-handed screw thread setting, and the upper side is a left-handed screw thread setting, the left-handed and right-handed of the left-handed and right-handed screw rods in this solution respectively represent the rotation direction of the screw when it moves, and the main function of the screw rod is to realize the conversion of rotational motion into linear motion, so that the slider 84 is realized by the left-handed and right-handed rotation of the bidirectional threaded rod 83 to slide in the transmission frame 81, thereby driving the connecting bracket 5 connected to the connecting plate 85 to move up and down.

[0037] See also Figure 1-2 The two limit plates 82 are respectively fixedly connected with a buffer pad 821 at one end close to the slider 84, and the side end of the connecting plate 85 is fixedly connected with a support block 811, and the support block 811 is movably connected to the inner wall of the transmission frame 81.

[0038] During use, the present solution can, through the support block 811, enable the connecting plate 85 to slide more stably and smoothly inside the chassis 1 under the connection of the slider 84. At the same time, under the setting of the buffer pad 821, the slider 84 has a certain buffering effect when it hits the surface of the buffer pad 821.

[0039] See also Figure 1 and Figure 3The emergency power-off component 11 includes a convex groove 111 opened on the inner wall of the chassis 1, a pressure-sensitive switch 112 is installed on the left wall of the convex groove 111, and the pressure-sensitive switch 112 is electrically connected to the heater 10. A placement frame 113 is embedded and installed inside the convex groove 111, and a copper sheet 114 is embedded and installed at the center end of the placement frame 113. A thermal pad 115 is fixedly connected to the right end of the placement frame 113, and a heat-absorbing pad 116 is fixedly connected to the right end of the thermal pad 115. The heat-absorbing pad 116 is in the same horizontal plane as the inner wall of the chassis 1, and a shape memory alloy pillar 117 is installed on the left end of the copper sheet 114, and a connecting sleeve 118 is fixedly connected to the left end of the shape memory alloy pillar 117.

[0040] During use of the present solution, when the temperature inside the chassis 1 gradually increases, the heat absorbing pad 116 first absorbs the temperature inside the chassis 1 and transfers it to the thermal conductive pad 115, and with the adsorption of the copper sheet 114, the heat is transferred to the surface of the shape memory alloy pillar 117, and the shape memory alloy pillar 117 gradually extends under the influence of heat, thereby contacting the pressure sensitive switch 112, so that the pressure sensitive switch 112 is triggered to cut off the power supply of the heater 10, and as the temperature inside the chassis 1 decreases, the shape memory alloy pillar 117 gradually begins to retract, so that the heater 10 can continue to perform heating work later, thereby greatly avoiding the occurrence of safety hazards caused by excessive temperature rise inside the chassis.

[0041] See also Figure 3 The outer end of the connection sleeve 118 is sleeved with a heat-insulating pad 119 , and the heat-insulating pad 119 contacts the inner wall of the placement frame 113 .

[0042] During use of this solution, by providing a heat preservation pad 119 on the outside of the connection sleeve 118 , the heat inside the chassis 1 can be transferred to the pressure sensitive switch 112 to a certain extent, thereby providing protection for the pressure sensitive switch 112 .

[0043] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
