Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a PET particle mixing and homogenizing device. Background Art
[0002] Before PET particles of different colors are sent to the injection molding machine for injection molding, they need to be stirred and mixed to achieve a homogenization effect. If a stirring paddle is only set in the center area of the mixing container, the stirring of the edge area is limited. If a stirring paddle is set in both the center area and the edge area, a better mixing and homogenization effect can be achieved, but because two power sources are set on the top of the mixing container, the overall volume and mass of the equipment are large, and the top load requirements of the mixing container are high.
[0003] If only one power source is used to control the stirring paddles in the center area and the edge area to stir, the large torque requirement will lead to the selection of a large motor power, resulting in a large overall volume and mass of the equipment, and there is still a problem of high requirements for the top load of the mixing container, and the overall effect is not good. Based on this, the utility model proposes a PET particle mixing and homogenizing equipment. Utility Model Content

[0016] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0019] The first ratchet mechanism 100 comprises a first inner ratchet 4, a first dial 5 is rotatably connected to the first inner ratchet 4, a plurality of first fixed ratchet grooves 6 are arranged on the circumference of the first inner ratchet 4, a first movable ratchet groove matching the first fixed ratchet groove is arranged on the circumference of the first dial 5, a first non-return pawl 8 rotatably connected to the first dial is arranged in the first movable ratchet groove 7, and a first elastic member 9 is arranged in the first movable ratchet groove 7, one end of which abuts against the bottom of the groove and the other end abuts against the first non-return pawl;
[0020] The second ratchet mechanism 200 comprises a second inner ratchet 10, a second dial 11 is rotatably connected to the second inner ratchet 10, a plurality of second fixed ratchet grooves 12 are arranged on the circumference of the second inner ratchet 10, a second movable ratchet groove 13 matching the second fixed ratchet groove is arranged on the circumference of the second dial 11, a second non-return pawl 14 rotatably connected to the second dial is arranged in the second movable ratchet groove 13, and a second elastic member 15 with one end abutting against the bottom of the groove and the other end abutting against the second non-return pawl is arranged in the second movable ratchet groove 13;
[0021] One end of the central shaft 2 is connected to the first dial 5, and the other end is connected to the second dial 11. The first dial 5 is connected to a power assembly 16 for controlling the rotation. The second inner ratchet 10 is provided with a hanger 17 for following. The hanger 17 is provided with a central stirring paddle 18 extending into the interior of the mixing container. The first inner ratchet 4 is provided with a driving sprocket 19. The edge shaft 3 is provided with a driven sprocket 20. A chain 21 is connected between the driven sprocket 20 and the driving sprocket 19. The edge shaft 3 is provided with an edge stirring paddle 22.
[0022] Furthermore, the first elastic member 9 and the second elastic member 15 are both compression springs.
[0023] Furthermore, the power assembly 16 includes a reduction motor.
[0024] In this embodiment,
[0025] When the power assembly 16 is in operation, the output shaft thereof rotates with the first dial 5 in a clockwise direction. Under the obstruction of the first non-return pawl 8, the first inner ratchet 4 is linked to drive the driving sprocket 19 to rotate, and the driven sprocket 20 and the chain 21 transmit the transmission, so that the edge shaft 3 rotates, and drives the stirring paddle 22 on the edge thereof to stir. Since the first ratchet mechanism 100 and the second ratchet mechanism 200 rotate in opposite directions, when the first inner ratchet 4 rotates, the second inner ratchet 10 rotates relative to the second dial 11, so that the central shaft 2 and the central stirring paddle 18 on it are not stirred in the mixing container 1.
[0026] When the power assembly 16 is in operation, the output shaft thereof rotates counterclockwise with the first dial 5, and under the obstruction of the second non-return pawl 14, the second inner ratchet 10 is linked to drive the hanger 17 to rotate, and the central shaft 2 and the central stirring paddle 18 thereon stir the mixing container 1; since the first ratchet mechanism 100 and the second ratchet mechanism 200 rotate in opposite directions, while the second inner ratchet 10 rotates, the first inner ratchet 4 rotates relative to the first dial 5, causing the sprocket mechanism to not transmit, and similarly, the edge shaft 3 and the edge stirring paddle 22 thereon do not stir the mixing container 1.
[0027] The PET particle mixing and homogenizing equipment involved in the utility model adopts a single power source in cooperation with two groups of ratchet mechanisms to respectively control the stirring and mixing of the central area and the edge area inside the mixing container; because the two groups of ratchet mechanisms are arranged in opposite directions, when the power source rotates in one direction, the central area inside the mixing container is stirred and mixed, and when the power source rotates in the other direction, the edge area inside the mixing container is stirred and mixed, so that only one power assembly needs to be installed on the top of the mixing container, the load is small, the PET particles are mixed evenly, the overall function is complete, and the practicability is strong.
