[0028] Embodiment 1: A high-efficiency mixing device for rubber compound, such as Figure 1-Figure 3 As shown, it includes a base 1, a slide 101, a connecting seat 102, a support seat 103, a mixing box 104, a rotor 105, a pressure hammer 106 and a turning mechanism. The base 1 is slidably connected to the slide 101 in the left-right direction, the slide 101 is fixedly connected to the connecting seat 102, and the connecting seat 102 is symmetrically connected to four supporting seats 103 for rotation. Two supporting seats 103 on the same side in the left-right direction are both fixedly connected to a mixing box 104. The upper end of the mixing box 104 is provided with There is an opening for feeding, and two rotors 105 are symmetrically connected to the internal mixing box 104 for rotation. A pressure hammer 106 is provided above the connecting seat 102, and the pressure hammer 106 is used to press into the opening at the upper end of the internal mixing box 104 for internal mixing. A flip mechanism is connected to the support seat 103, and the slide seat 101 is used to drive the internal mixing box 104 to move. When one of the internal mixing boxes 104 moves to the bottom of the pressure hammer 106, the flip mechanism will drive the other internal mixing box 104 to rotate for easy discharge.

[0029] The internal mixing box 104, the rotor 105 and the pressure hammer 106 are components of the internal mixing machine in the prior art. The internal mixing principle of the internal mixing machine can refer to the prior art and will not be described in detail here. When the internal mixing box 104 on the left is located directly below the pressure hammer 106, raw materials have been added to the internal mixing box 104 on the left, and then the pressure hammer 106 is controlled to move downward into the opening of the internal mixing box 104 on the left, and the two rotors 105 in the internal mixing box 104 on the left are controlled to rotate relative to each other to start internal mixing. During this process, the flipping mechanism is controlled to drive the internal mixing box 104 on the right to rotate ninety degrees clockwise, and the rubber that has been internally mixed in the internal mixing box 104 on the right is taken out. After the rubber is taken out, the flipping mechanism is controlled to drive the internal mixing box 104 to rotate counterclockwise to reset. , and then add new raw materials to the right mixing box 104; when the rubber in the left mixing box 104 is mixed, first control the pressure hammer 106 to reset upwards, and then control the slide 101 to slide a fixed distance to the left. After the slide 101 moves, the right mixing box 104 will move to just below the pressure hammer 106, and then control the pressure hammer 106 to enter the opening of the right mixing box 104 downward to continue mixing. During this process, the flipping mechanism is controlled to drive the left mixing box 104 to rotate counterclockwise by ninety degrees, and the mixed rubber in the left mixing box 104 is taken out. After taking out the rubber, the flipping mechanism is controlled to drive the mixing box 104 to rotate clockwise and reset, and then new raw materials are added to the left mixing box 104, and the operation is circulated.

[0030] like Figure 2-Figure 5As shown, the flipping mechanism includes a flipping shaft 2, an articulated head 201, a sliding rod 202, a driven frame 203, an adjusting plate 204, a plug-in plate 205, a No. 1 spring 206, an active seat 207, a first hydraulic cylinder 208 and an adjusting assembly. The end of the support seat 103 away from the sliding seat 101 is fixedly connected with a flipping shaft 2. The flipping shaft 2 is located at an eccentric position on the support seat 103, and the flipping shaft 2 on the two support seats 103 on the right is longer, while the flipping shaft 2 on the two support seats 103 on the left is shorter. The flipping shaft 2 is rotatably connected with a hinged head 201, and a sliding rod 202 is fixedly connected to the articulated head 201. The sliding rods 202 on the same side in the left and right directions are slidably connected with the driven frames 203 together. There are two driven frames 203 in total, but the lengths of the two driven frames 203 are different to prevent the sliding rods 202 on the left and right sides from moving upward. In case of a collision, an adjusting plate 204 is slidably connected to the driven frame 203 through a guide rod, and a No. 1 spring 206 is sleeved on the guide rod. When the adjusting plate 204 moves to the opposite side, the No. 1 spring 206 will be compressed. A plug-in plate 205 is fixedly connected to the lower end of the adjusting plate 204, and the plug-in plate 205 is an inverted T-shaped structure. An active seat 207 is slidably connected to the slide 101 in the vertical direction. A first hydraulic cylinder 208 is fixedly connected to the slide 101, and the output shaft of the first hydraulic cylinder 208 is fixedly connected to the active seat 207. A notch is provided on the active seat 207 for facilitating the insertion of the plug-in plate 205. An adjusting component for driving the plug-in plate 205 to be inserted into the active seat 207 is connected to the base 1. When the slide 101 slides to the right, the adjusting component will drive the plug-in plate 205 on the right to be inserted into the active seat 207, and vice versa. The plug-in plate 205 on the left is driven to be inserted into the active seat 207.

[0031] When the sliding seat 101 moves to the right to drive the mixing box 104 on the left to move to the bottom of the pressure hammer 106, the adjusting assembly drives the right plug-in plate 205 to be inserted into the active seat 207, and the plug-in plate 205 drives the adjusting plate 204 to move to compress the No. 1 spring 206, and then controls the first hydraulic cylinder 208 to extend, and the first hydraulic cylinder 208 drives the right driven frame 203 to move upward through the active seat 207 and the plug-in plate 205. When the right driven frame 203 moves upward, it drives the connected support seat 103 to rotate clockwise through the hinge joint 201, the slide rod 202 and the flip shaft 2, thereby driving the right mixing box 104 to rotate ninety degrees clockwise. When the rubber in the mixing box 104 is taken out, the first hydraulic cylinder 208 is controlled to contract, thereby The right side driven frame 203 is driven downward by the active seat 207 and the plug-in plate 205, thereby driving the right side internal mixing box 104 to rotate counterclockwise and reset, so as to add new raw materials to the right side internal mixing box 104. When the active seat 207 is reset downward, the compressed No. 1 spring 206 will push the right side plug-in plate 205 to reset, and the reset plug-in plate 205 will be out of contact with the active seat 207; during the movement of the sliding seat 101 to the left, the adjusting component will drive the left side plug-in plate 205 to be inserted into the active seat 207. When the active seat 207 drives the left side driven frame 203 to move upward through the plug-in plate 205, it will drive the left side internal mixing box 104 to rotate counterclockwise by ninety degrees. When the active seat 207 moves downward, it will drive the left side internal mixing box 104 to rotate clockwise and reset.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown, the adjustment assembly includes an adjustment seat 3, a push rod 301, a resistance rod 302 and a locking block 303. Two adjustment seats 3 are fixedly connected to the base 1, and the two adjustment seats 3 are located on the left and right sides of the slide 101. Two push rods 301 are fixedly connected to one end of the adjustment seat 3 close to the slide 101, and the lower end of the plug-in board 205 is fixedly connected to the resistance rod 302. The push rod 301 pushes the resistance rod 302 to make the plug-in board 205 slide. Four locking blocks 303 are fixedly connected to the slide 101 in a left-right symmetrical manner. The locking blocks 303 are used to limit the upward movement of the plug-in board 205 that is not inserted into the active seat 207.

[0033] When the slide 101 moves to the right, the top rod 301 on the right adjusting seat 3 will contact the abutment rod 302 on the right plug-in board 205, thereby limiting the right plug-in board 205 and the adjusting plate 204 from continuing to move to the right. Since the slide 101 will drive the active seat 207 to move to the right synchronously, the plug-in board 205 will be inserted into the active seat 207. When the active seat 207 drives the driven frame 203 and the plug-in board 205 to move upward, the abutment rod 302 has a certain length, so The top rod 301 can always maintain contact with the resistance rod 302 to prevent the No. 1 spring 206 from pushing the plug-in board 205 and the adjustment plate 204 to reset; when the plug-in board 205 is reset under the push of the No. 1 spring 206, it will move to the bottom of the locking block 303, and the locking block 303 will be stuck between the adjustment plate 204 and the plug-in board 205, so that the driven frame 203 cannot move upward and downward, thereby locking the support seat 103 to prevent the support seat 103 from driving the mixing box 104 to rotate at will.

[0034] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a material taking mechanism for automatically taking out the rubber, which is arranged on the left and right sides of the slide 101. The material taking mechanism includes a material taking bracket 4, a sliding frame 401, a second spring 402, a lifting frame 403, a tension spring 404, a scraper plate 405, a lever 406, a power plate 407 and a scraper rod 408. The left and right sides of the slide 101 are fixed with a material taking bracket 4, and the material taking bracket 4 is slidably connected to the sliding frame 401 along the left and right directions. The guide rod of the sliding frame 401 is sleeved with a second spring 402. When the sliding frame 401 slides in the direction away from the slide 101, the second spring 402 will be compressed. The upper side of the sliding frame 401 is slidably connected to the lifting frame 403 along the vertical direction, and the guide rod of the lifting frame 403 is sleeved with a tension spring 404. The upper end of the tension spring 404 is fixedly connected to the lifting frame 403, and the lower end of the tension spring 404 is fixedly connected to the sliding frame 401. A scraper plate 405 is fixedly connected to the lifting frame 403, and a plurality of scraper rods 408 are equidistantly fixedly connected to the lower end of the scraper plate 405. The lower end of the scraper rod 408 is in the shape of a spike. A lever rod 406 is fixedly connected to the sliding frame 401. Two rotors 105 are rotatably connected in each mixing box 104, and a power-assisting plate 407 is fixedly connected to the rotating shaft of one of the rotors 105. The power-assisting plate 407 is located outside the mixing box 104. The power-assisting plate 407 is squeezed and matched with the lever rod 406 to drive the sliding frame 401 to move away from the mixing box 104. A guide assembly is connected to the lifting frame 403, and the guide assembly is used to move the lifting frame 403 along a right-angled trapezoidal trajectory.

[0035] The rotor 105 will drive the assisting plate 407 to rotate synchronously during the rotation process. When the rubber is mixed, the rotor 105 will be stopped first to Figure 2 Take the mixing box 104 on the right side as an example, and Figure 2 The assisting plate 407 in the middle stops in a horizontal state. After the flip mechanism drives the right side mixing box 104 to rotate ninety degrees clockwise, the second spring 402 will push the sliding frame 401 to slide in the direction close to the mixing box 104, so that the scraper plate 405 can enter the mixing box 104, and the lever 406 on the sliding frame 401 can approach the assisting plate 407, and then the rotor 105 is controlled to continue to rotate, thereby driving the assisting plate 407 to rotate. During the rotation of the assisting plate 407, the lever 406 will be gradually squeezed. During the gradual squeezing process, the lever 406 will push the sliding frame 401 to move away from the mixing box 104, and then the assisting plate 407 will gradually cancel the squeezing of the lever 406. During the gradual cancellation of the squeezing process, the second spring 402 will push the sliding frame 401 to move in the direction close to the mixing box 104; when the sliding frame 401 moves close to the mixing box 104 During the directional movement, the lifting frame 403 will first move synchronously with the sliding frame 401 under the action of the guide component. When the scraper plate 405 enters the mixing box 104 and is about to contact the rotor 105 inside the mixing box 104, the lifting frame 403 will move downward under the action of the tension spring 404, thereby driving the scraper plate 405 to move downward; in the process of the sliding frame 401 moving away from the mixing box 104, the scraper plate 405 and the scraper rod 408 will scrape the rubber in the mixing box 104 outwards. When the scraper plate 405 is moved out of the mixing box 104, the lifting frame 403 will tilt upward and reset under the action of the guide component, and the tension spring 404 will be stretched and stored, so that during the rotation of the power plate 407, the lifting frame 403 can be driven to move along a right-angled trapezoidal trajectory, so as to automatically scrape out the rubber in the mixing box 104.

[0036] like Figure 6 and Figure 8As shown, the guide assembly includes a No. 1 guide block 5, a No. 2 guide block 501, a guide rotating plate 502, a torsion spring 503 and an adjusting rod 504.

The No. 1 guide block 5 is rotatably connected with a guide rotating plate 502. The guide rotating plate 503 is provided on the No. 1 guide block 5. A torsion spring 503 is sleeved on the rotating shaft of the plate 502, one end of the torsion spring 503 is fixedly connected to the rotating shaft of the guide rotating plate 502, and the other end of the torsion spring 503 is fixedly connected to the No. 1 guide block 5. An adjusting rod 504 is fixedly connected to the lifting frame 403. When the sliding frame 401 approaches the mixing box 104, the adjusting rod 504 will slide along the top of the No. 1 guide block 5, the guide rotating plate 502 and the No. 2 guide block 501. When the sliding frame 401 moves away from the mixing box 104, the adjusting rod 504 will slide upward along the inclined channel.

[0037] When the sliding frame 401 moves toward the mixing box 104, the adjusting rod 504 moves toward the mixing box 104 along the top of the second guide block 501, the guide rotating plate 502 and the first guide block 5. When the scraper plate 405 enters the mixing box 104 and moves to the point where the scraper plate 405 is about to contact the rotor 105, the adjusting rod 504 moves away from the top of the second guide block 501, so that the tension spring 404 can drive the lifting frame 403 to move downward, and drive the scraper plate 405 downward to approach the rubber in the mixing box 104. When the sliding frame 401 moves away from the mixing box 104, the adjusting rod 504 moves away from the second guide block 501. 04, the adjusting rod 504 will move under the lower side of the No. 1 guide block 5. Since the lower end of the No. 2 guide block 501 is lower than the lower end of the No. 1 guide block 5, the adjusting rod 504 will contact the inclined surface of the No. 1 guide block 5 during the movement, and in the process that the sliding frame 401 continues to move away from the mixing box 104, the adjusting rod 504 will move upward along the inclined surface of the No. 1 guide block 5, thereby driving the lifting frame 403 to move upward, the tension spring 404 will be stretched, and the adjusting rod 504 will push the guide rotating plate 502 to rotate, and the torsion spring 503 will be charged. When the adjusting rod 504 moves to Figure 8 When the top of the second guide block 501 is raised, it will be out of contact with the guide rotating plate 502, and the guide rotating plate 502 will rotate and return to the original position under the action of the torsion spring 503. Figure 8 The horizontal state shown in .

[0038] like Figure 2As shown, it also includes a limit assembly for preventing the sliding frame 401 from affecting the rotation and reset of the mixing box 104. The limit assembly is installed on the adjustment seat 3. The limit assembly includes a limit seat 6, a limit rod 601 and a No. 3 spring 602. Two limit seats 6 are symmetrically fixed on the adjustment seat 3. The limit seat 6 is slidably connected with a limit rod 601 in a vertical direction. The limit rod 601 is used to prevent the sliding frame 401 from sliding toward the mixing box 104. The guide rod of the limit rod 601 is sleeved with a No. 3 spring 602. When the limit rod 601 moves downward, the No. 3 spring 602 will be compressed. When the flipping mechanism drives the mixing box 104 to flip and discharge, the mixing box 104 will press the limit rod 601 downward to cancel the restriction on the sliding frame 401.

[0039] During the rotation and reset process of the internal mixer box 104, it is necessary to prevent the scraper plate 405 from moving into the internal mixer box 104 to prevent the scraper plate 405 from affecting the rotation and reset of the internal mixer box 104; Figure 1 and Figure 5 The sliding frame 401 shown in the figure is in a state of being blocked by the limit rod 601, and the second spring 402 is in a compressed state. Taking the right side internal mixer 104 as an example, when the flip mechanism drives the right side internal mixer 104 to rotate clockwise, Figure 2 It can be seen that a protrusion is provided on the top of the left side of the limit rod 601. During the rotation of the mixing box 104, the limit rod 601 will be pressed downward by the protrusion on the top of the left side, and the third spring 602 will be compressed. When the mixing box 104 rotates 90 degrees, the limit rod 601 just cancels the obstruction of the sliding frame 401, so that the second spring 402 can push the sliding frame 401 to move closer to the mixing box 104, and enable the lever 406 to approach the power plate 407 and cooperate with each other. When it is necessary to control the internal mixing box 104 to rotate and reset, first rotate the assisting plate 407 to a horizontal state, and the assisting plate 407 pushes the lever 406 to move the sliding frame 401 to the right side of the limiting rod 601, and then control the internal mixing box 104 to rotate and reset, the internal mixing box 104 will gradually lose contact with the limiting rod 601, and the No. 3 spring 602 will push the limiting rod 601 to reset upward, and the limiting rod 601 after resetting upward will prevent the sliding frame 401 from moving toward the direction of the internal mixing box 104.

[0042] like Figure 3 As shown, it also includes a gear 8 and a second motor 801 for driving the rotor 105 to rotate. The gear 8 is fixedly connected to the rotating shaft of the rotor 105. The gear 8 is located on the outside of the internal mixing box 104, and the gears 8 on the two rotors 105 of the same internal mixing box 104 are meshed. The second motor 801 is fixedly connected to one of the support seats 103 on the right, and the second motor 801 is also fixedly connected to one of the support seats 103 on the left.

The feeding mechanism includes a main frame 9, a material box 901, a side frame 902, an electric push rod 903 and a discharge plate 904. Four main frames 9 are symmetrically fixed to the base 1, and two main frames 9 on the same side in the left and right directions are commonly fixed with a material box 901, the material box 901 is used to store raw materials, and the lower end of the material box 901 is provided with an opening, and the opposite ends of the two material boxes 901 are fixed with a side frame 902, the material picking bracket 4 is fixed to the side frame 902 on the same side, the side frame 902 is fixed with an electric push rod 903, the opening at the lower end of the material box 901 is slidably connected to the discharge plate 904 along the left and right directions, and the telescopic axis of the electric push rod 903 is fixed to the adjacent discharge plate 904.

[0045] The raw materials are added to the material box 901 in advance. When the rubber in the internal mixing box 104 is taken out and rotated to reset, the electric push rod 903 on the same side of the internal mixing box 104 is controlled to retract. The electric push rod 903 drives the discharge plate 904 to no longer block the raw materials from flowing out of the material box 901, so that the raw materials in the material box 901 can flow downward into the internal mixing box 104, realizing the function of automatic loading. After the loading is completed, the electric push rod 903 is controlled to extend so that the discharge plate 904 continues to block the raw materials from flowing out.
