Description

Technical Field

[0001] This utility model relates to the technical field of internal mixers, and in particular to a multi-component synchronous feeding internal mixing device for aviation tire rubber compounds. Background Technology

[0002] A laboratory internal mixer is a small, closed-loop device used for mixing polymer materials such as rubber and plastics. Through the shearing and extrusion action of the rotor in a closed cavity, raw rubber and compounding agents are mixed efficiently. It is suitable for formula development, process optimization, and small-batch production.

[0003] The prior art Chinese utility model patent with application number CN200920265279.0 relates to a rubber internal mixer, including a base, main platform, upper seat, counterweight, gearbox and motor, which can prevent problems such as uneven rubber mixing or charring caused by excessively rapid or uneven heating.

[0004] However, in actual use, the above-mentioned devices require the materials to be premixed before being added to the equipment, or the materials to be added to the equipment step by step. Either way, the production efficiency of the equipment will be reduced. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-component synchronous feeding internal mixing device for aviation tire rubber materials. The internal mixing process is sealed to reduce the impact of the external environment on the internal mixing process. Multiple materials are simultaneously added into the equipment through a feeding device. A limiting device works in conjunction with the feeding device to facilitate the reset of the feeding device and reduce the impact on the assembly operation of the internal mixing device after the feeding is completed. This improves the practicality of the device.

[0006] This utility model discloses a multi-component synchronous feeding and mixing device for aviation tire rubber compounds; it includes a mixing device, a feeding device, and a limiting device. The feeding device is installed on the mixing device, and the limiting device is installed on the mixing device. The mixing device performs intensive mixing processing on the raw materials, and the mixing process is sealed to reduce the impact of the external environment on the mixing process. The feeding device simultaneously adds multiple materials into the equipment. The limiting device works in conjunction with the feeding device to facilitate the resetting of the feeding device, reduce the impact on the assembly operation of the mixing device after the feeding is completed, and improve the practicality of the device.

[0007] Preferably, the internal mixing device includes a frame, a dual-output reducer, a drive motor, mixing rollers, a gantry, an electric cylinder, and a sealing cover. The dual-output reducer is mounted on the left side of the frame, and the drive motor is mounted on the dual-output reducer. A chamber is provided inside the frame, and two sets of mixing rollers are installed in the chamber. The two output ends of the dual-output reducer are respectively connected to the two sets of mixing rollers. A feed inlet is provided at the upper part of the chamber. A gantry is mounted on the upper surface of the frame, and an electric cylinder is mounted on the upper surface of the gantry. The moving end of the electric cylinder extends through the upper surface of the gantry to the lower part of the electric cylinder and connects to the sealing cover. The sealing cover can seal the feed inlet. Material is added to the chamber of the frame, and then the electric cylinder is controlled to extend, causing the sealing cover to fall and seal the feed inlet in the chamber, reducing the impact of the external environment on the mixing process. Then, the drive motor is turned on, transmitting power through the dual-output reducer to the two sets of mixing rollers, driving them to rotate, thereby providing power for the mixing process and improving the practicality of the device.

[0008] Preferably, the feeding device includes a sliding seat, a feeding pipe, a geared motor, and a spiral blade. Multiple sets of sliding seats are inclinedly arranged on the side of the gantry. A circular hole is provided in the middle of the sliding seat. The main body of the feeding pipe is inserted into the circular hole of the sliding seat. A geared motor is installed on the outer end face of the feeding pipe. A spiral blade is installed in the feeding pipe. The output end of the geared motor is connected to the spiral blade. A feed inlet is provided on the outer side of the feeding pipe. The sliding seat limits the placement angle of the feeding pipe. The geared motor is turned on to transmit power to the spiral blade, which drives the spiral blade to rotate, thereby feeding the material into the chamber of the frame. The feeding process is completed by the synchronous operation of multiple sets of feeding pipes, which improves the production efficiency of the equipment and the practicality of the device.

[0009] Preferably, it also includes a storage hopper, which is connected to the inlet of the feeding pipe; the storage hopper stores the material, which facilitates feeding operations in conjunction with the feeding device and improves the practicality of the device.

[0010] Preferably, the limiting device includes a limiting sleeve, a lead screw, a spring, and a limiting nut. Multiple sets of limiting sleeves are provided on the side of the feeding tube, and multiple sets of connecting slots are provided on the sliding seat corresponding to the positions of the limiting sleeves. A lead screw is installed in each slot. A circular insertion hole is provided in the middle of the limiting sleeve, and a spring is installed at the bottom of the connecting slot. The limiting nut is connected to the lead screw via a nut. The limiting nut, in conjunction with the limiting sleeve, limits the movable range of the feeding tube body. The limiting sleeve and lead screw limit the movement of the feeding tube within the sliding seat, while the spring facilitates the reset of the feeding tube, improving the practicality of the device.

[0011] Preferably, the device also includes a drive electric cylinder. A drive electric cylinder is installed on the inner side of the gantry corresponding to the upper part of multiple sets of sliding seats. The moving end of the drive electric cylinder is connected to the upper part of the output end of the feeding pipe. By controlling the extension of the drive electric cylinder, the feeding pipe moves in the sliding seat. When feeding is required, the drive electric cylinder is extended so that the output end of the feeding pipe extends to the upper side of the feed inlet of the frame. This helps to reduce material spillage when feeding with the feeding device. By controlling the retraction of the drive electric cylinder, the feeding pipe is moved back with the help of a spring, preventing the output end of the feeding pipe from affecting the up and down movement of the sealing cover, thus improving the practicality of the device.

[0012] Preferably, the device also includes limiting light rods and guide sleeves. Multiple sets of limiting light rods are provided on the upper surface of the sealing cover, and multiple sets of guide sleeves are provided on the upper side of the upper surface of the gantry corresponding to the multiple sets of limiting light rods. The upper parts of the multiple sets of limiting light rods are inserted into the multiple sets of guide sleeves. The lifting and lowering process of the sealing cover is limited by the multiple sets of limiting light rods and guide sleeves, which reduces the vibration amplitude of the sealing cover itself during the lifting and lowering process and improves the stability and practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the raw materials are processed by internal mixing device, the internal mixing process is sealed to reduce the impact of the external environment on the internal mixing process, multiple materials are added into the equipment at the same time by feeding device, and the operation of the feeding device is coordinated with the limiting device to facilitate the reset of the feeding device, reduce the impact on the assembly operation of the internal mixing device after the feeding is completed, and improve the practicality of the device.
