[0002] Plastic color matching machines are used to produce various plastic products, such as plastic toys, plastic tableware, and plastic appliance casings. Through precise color matching, products can have a rich variety of colors, improving their aesthetics and market competitiveness. The cooling mechanism of the plastic color matching machine is an important component, mainly used to control the temperature during the color matching process to ensure the normal operation of the equipment and the quality of color matching.

[0003] In the prior art, patent CN202321609938.4 discloses a cooling mechanism for a plastic color matching machine, including a color matching machine housing and a stirring chamber disposed within the color matching machine housing. The stirring chamber has a feeding channel for plastic particles to enter the stirring chamber and a discharge channel for plastic particles to exit the stirring chamber downwards. A cooling channel is provided on the color matching machine housing located outside the stirring chamber and / or the feeding channel and / or the discharge channel. The color matching machine housing is made of a thermally conductive material, and the liquid inlet and liquid outlet of the cooling channel are respectively connected to an external cooling medium.

[0004] The above-mentioned cooling mechanism has some problems in actual use. For example, heat is generated during the mixing of plastic masterbatch and pigment powder. If this heat cannot be dissipated in time, the color matching quality may be reduced. Therefore, we propose a cooling mechanism for plastic color matching machine. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This embodiment provides a technical solution: a cooling mechanism for a plastic color matching machine, including a worktable 1 and an auxiliary cooling adjustment component 2 for the machine body;

[0026] Workbench 1: A placement platform 7 (the middle part of the placement platform 7 is an aluminum alloy plate) is fixedly connected to its upper side. A control switch 4 is provided on the outside of the mechanism. The input end of the control switch 4 is electrically connected to an external power source. When the mechanism is needed, the mechanism is placed at the lower end of the mixing paddle of the plastic color mixing machine, and then the color mixing cylinder 3 is placed on the placement platform 7.

[0027] The auxiliary cooling adjustment assembly 2 includes a bottom limiting frame 21, a sliding seat 23, a connecting rod frame 24, an upper angle adjustment frame 25, and an arc-shaped contact surface 26. The bottom limiting frame 21 is fixedly connected to the middle of the upper side wall of the workbench 1. The sliding seat 23 is slidably connected inside the bottom limiting frame 21. The connecting rod frames 24 are rotatably connected inside the sliding seat 23. The upper ends of the four connecting rod frames 24 are rotatably connected to the upper angle adjustment frames 25, and the lower ends of the four upper angle adjustment frames 25 are rotatably connected to the upper side of a placement platform 7. The middle part of the side of the four upper angle adjustment frames 25 facing the center of the workbench 1 is fixedly connected to the arc-shaped contact surface 26 (the arc-shaped contact surface 26 is an arc-shaped aluminum alloy plate). The auxiliary cooling adjustment assembly 2 also includes... A lead screw 22 and an adjusting motor 27 are connected. The lead screw 22 is rotatably connected between the upper and lower inner walls of the bottom limiting frame 21. The external thread of the lead screw 22 is threadedly connected to the middle of the sliding seat 23. The lower end of the bottom limiting frame 21 is fixedly connected to the adjusting motor 27. The output shaft of the adjusting motor 27 is fixedly connected to the lower end of the lead screw 22. The input end of the adjusting motor 27 is electrically connected to the output end of the control switch 4. A color matching cylinder 3 is placed in the middle of the upper surface of the placement platform 7. The arc surfaces of the four arc-shaped contact surfaces 26 are in contact with the outer arc surfaces of the color matching cylinder 3. The upper side wall of the placement platform 7 and the side of the four arc-shaped contact surfaces 26 away from the center of the workbench 1 are respectively fixedly connected to heat dissipation fin groups 5 (the heat dissipation fin groups 5 are integrated with the aluminum alloy plate). The middle part of the five heat dissipation fin groups 5 is provided with coolant circulation pipes. 6. The inlet and outlet ends of the five sets of coolant circulation pipes 6 are connected to the external coolant circulation equipment via hoses. A support is provided on the lower side of the workbench 1, and the height of the support is higher than the height of the bottom limit frame 21. The upper surface of the workbench 1 has evenly distributed clearance grooves, which are slidably connected to the outer surface of the connecting rod frame 24 located on the same side. At this time, the control switch 4 can be adjusted to adjust the operation of the motor 27. The output shaft of the motor 27 is adjusted to rotate in the forward and reverse directions, which in turn drives the lead screw 22 to rotate in the forward and reverse directions, which in turn drives the sliding seat 23 to adjust its height. During the height adjustment of the sliding seat 23, the connecting rod frame 24 pulls or lifts the upper angle adjustment frame 25, so that all four upper angle adjustment frames 25 rotate around their lower ends as the central axis. Angle adjustment: When the sliding seat 23 moves to its highest position, the four upper angle adjustment brackets 25 facing the center of the worktable 1 are in a vertical state. At this time, the arc surface of the curved bonding surface 26 is completely in contact with the outer arc surface of the color mixing cylinder 3. Plastic masterbatch and pigment powder can then be manually added into the color mixing cylinder 3. The plastic color mixing machine can then be started, and its stirring paddle begins to rotate, thoroughly mixing the plastic masterbatch and pigment powder inside the color mixing cylinder 3. Most of the heat generated during mixing is conducted through the curved bonding surface 26 and the placement table 7, dissipating the heat to the heat dissipation fin assembly 5. The external coolant circulation system can then be adjusted, and the coolant flows sequentially through the coolant circulation pipe 6, carrying away the heat.After adjustment, stop the external coolant circulation equipment and the external plastic color mixing machine. Then, adjust control switch 4 to reset the side angle adjustment bracket 25. During the color mixing process, heat will be carried away in real time. At this time, the temperature of the color mixing cylinder 3 is not high. Manually remove the color mixing cylinder 3 and take out the mixed plastic masterbatch and pigment powder.

[0028] The working principle of the cooling mechanism for a plastic color mixing machine provided by this utility model is as follows: When the mechanism is needed, it is placed at the lower end of the mixing paddle of the plastic color mixing machine, and then the color mixing cylinder 3 is placed on the placement platform 7. At this time, the control switch 4 can be adjusted to operate the motor 27, and the output shaft of the motor 27 can be adjusted to rotate in both directions, thereby driving the lead screw 22 to rotate in both directions, and thus driving the sliding seat 23 to adjust its height. During the height adjustment of the sliding seat 23, the connecting rod frame 24 will pull or lift the upper angle adjustment frame 25, so that the four upper angle adjustment frames 25 can adjust their angles around their lower ends as the central axis. When the sliding seat 23 moves to the highest position, the side of the four upper angle adjustment frames 25 facing the center of the worktable 1 is in a vertical state. At this time, the arc surface of the arc-shaped contact surface 26 is completely in contact with the outer arc surface of the color mixing cylinder 3. Plastic masterbatch and pigment powder can be manually added into the color mixing cylinder 3. At this time, the operation of the plastic color mixing machine can be adjusted, and the stirring paddle of the plastic color mixing machine will start to rotate, thoroughly mixing the plastic masterbatch and pigment powder inside the color mixing cylinder 3. Most of the heat will be generated during the mixing process. This heat will be conducted through the arc-shaped bonding surface 26 and the placement platform 7, and dissipated to the heat dissipation fin assembly 5. At this time, the external coolant circulation device can be adjusted, and the coolant will flow through the coolant circulation pipe 6 in sequence, thus carrying away the heat. After the adjustment is completed, the external coolant circulation device and the external plastic color mixing machine can be stopped. Then, the control switch 4 can be adjusted to reset the side angle adjustment bracket 25. During the color mixing process, the heat will be carried away in real time. At this time, the temperature of the color mixing cylinder 3 is not high. The color mixing cylinder 3 can be manually removed, and the mixed plastic masterbatch and pigment powder can be taken out.

[0029] It is worth noting that the regulating motor 27 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended that the regulating motor 27 be a high-torque geared motor of model JK1545. The control switch 4 is provided with a control button corresponding to the regulating motor 27 and used to control its switch.
