[0050] like Figures 1-6 As shown, this utility model provides a constant temperature filling mechanism, which includes a workbench 10, a liquid storage tank 20, a filling cylinder 30, a constant temperature water tank 50, a constant temperature pipeline system 60, and a feeding assembly 80.
[0051] It should be noted that the constant temperature water tank 50 contains a high-temperature medium, which can be water or heat transfer oil. The constant temperature water tank 50 is equipped with a heating rod, which is connected to an external power source and can heat the high-temperature medium at a constant temperature. The heating method of the heating rod is existing technology and will not be described in detail.
[0052] In a specific embodiment, the workbench 10 is provided with a support base 11, and a first chamber 111 is provided inside the support base 11. The filling cylinder 30 is installed on the support base 11. The cylinder wall of the filling cylinder 30 is provided with a heat-conducting pipe 33. The bottom of the filling cylinder 30 is provided with a discharge port 34, and the discharge port 34 is connected to a guide cylinder 35. The feeding assembly 80 is connected to the guide cylinder 35. The liquid storage tank 20 is sleeved on the outer peripheral wall of the guide cylinder 35 and forms a second chamber 22 with the guide cylinder 35. The constant temperature water tank 50 is provided on the side of the workbench 10, and a circulation pump is provided inside the constant temperature water tank 50. The constant temperature pipeline system 60 is connected to the circulation pump. Next, the constant temperature pipeline system 60 is sequentially connected to the heat conduction pipe 33, the feeding assembly 80, the second chamber 22, the first chamber 111, and the constant temperature water tank 50 to form a circulation loop. In this way, by setting up the constant temperature pipeline system 60, the heat conduction pipe 33, the feeding assembly 80, the second chamber 22, the first chamber 111, and the constant temperature water tank 50 can be sequentially connected to form a circulation loop, so that the high temperature medium in the constant temperature water tank 50 can circulate and heat the filling cylinder 30 and the feeding assembly 80, ensuring that the cosmetic emulsion or paste is in a molten state throughout the filling process, thereby improving filling efficiency.
[0053] In some embodiments, the filling cylinder 30 includes an outer cylinder 31 and an inner cylinder 32, which together form a sealed space. The heat-conducting pipe 33 is disposed in the sealed space and is spirally arranged around the inner cylinder 32. On the one hand, this can prevent leakage of the heat-conducting pipe 33 from contaminating the object to be filled. On the other hand, the outer cylinder 31 can act as an isolation to prevent workers from accidentally touching the heat-conducting pipe 33 and causing damage. The spiral arrangement of the heat-conducting pipe 33 can ensure the temperature of the entire filling cylinder 30 is uniform, so as to achieve uniform heating of the object to be filled.
[0054] In some embodiments, the surface of the outer cylinder 31 may be coated with a heat-insulating coating to reduce heat loss and save resources.
[0055] In some embodiments, the heat pipe 33 has an inlet end and an outlet end. Along the axial direction of the filling cylinder 30, the height of the inlet end of the heat pipe 33 is greater than the height of the outlet end of the heat pipe 33. The constant temperature pipeline system 60 includes a first pipeline 61. One end of the first pipeline 61 is connected to a circulation pump, and the other end is connected to the inlet end of the heat pipe 33. In this way, the high temperature medium is transported to the first pipeline 61 by the circulation pump and enters the heat pipe 33. Under the spiral arrangement of the heat pipe 33, it can exchange heat with the inner cylinder 32. The inner cylinder 32 then exchanges heat with the object to be filled, thereby realizing the heating of the object to be filled.
[0056] In some embodiments, the feeding assembly 80 includes a feeding pipe, which includes an outer pipe 81 and an inner pipe 82 disposed within the outer pipe 81. One end of the inner pipe 82 is connected to the guide cylinder 35, and a third chamber 83 is formed between the outer pipe 81 and the inner pipe 82. The constant temperature pipeline system 60 also includes a second pipeline 62, one end of which is connected to the liquid outlet end of the heat-conducting pipe 33, and the other end is connected to the third chamber 83. Specifically, the outer pipe 81 has a first port and a second port connected to the third chamber 83, and the second pipeline 62 is connected to the first port of the outer pipe 81. Thus, the high-temperature medium output by the heat-conducting pipe 33 enters the third chamber 83 through the second pipeline 62, which can further heat the feeding pipe, so that the object to be filled still maintains the set temperature when passing through the feeding pipe, and avoids the object to be filled from solidifying in the feeding pipe and causing blockage.
[0057] In some embodiments, after the object to be filled enters the discharge pipe, the temperature of the end of the object near the guide cylinder 35 is higher than the temperature of the end away from the guide cylinder 35. In order to achieve temperature stability of the object to be filled, the distance between the first port of the outer tube 81 and the guide cylinder 35 is greater than the distance between the second port of the outer tube 81 and the guide cylinder 35. Thus, the flow direction of the object to be filled in the discharge pipe is opposite to the flow direction of the high-temperature medium in the third chamber 83, thereby further improving the heat exchange efficiency and making the temperature of the object to be filled more stable after passing through the discharge pipe.
[0058] In some embodiments, the constant temperature pipeline system 60 further includes a third pipeline 63, one end of which is connected to the second port of the outer pipe 81 and the other end of which is connected to the second chamber 22. In this way, after the high temperature medium enters the second chamber 22, it can further exchange heat with the guide cylinder 35, ensuring that the temperature of the object to be filled is more stable when it passes through the guide cylinder 35, and avoiding the object to be filled from solidifying inside the guide cylinder 35 and causing blockage.
[0059] In some embodiments, the constant temperature filling mechanism further includes a discharge valve 84, a filling nozzle 90, a fourth pipe 64, a fifth pipe 65, and a sixth pipe 66. The discharge valve 84 is located at the end of the discharge pipe away from the guide cylinder 35 and has an output end. The filling nozzle 90 is detachably installed at the output end of the discharge valve 84 and has an outer wall and an inner wall, forming a sealed fourth chamber between the outer wall and the inner wall. The filling nozzle 90 has a third port and a fourth port communicating with the fourth chamber. One end of the fourth pipe 64 communicates with the second chamber 22, and the other end communicates with the filling nozzle 90. The third port is connected; one end of the fifth pipe 65 is connected to the fourth port of the filling nozzle 90, and the other end is connected to the first chamber 111; one end of the sixth pipe 66 is connected to the first chamber 111, and the other end is connected to the constant temperature water tank 50; thus, the high temperature medium enters the fourth pipe 64 from the second chamber 22 and further insulates the filling nozzle 90. After that, the high temperature medium enters the first chamber 111 through the fifth pipe 65 for storage, and flows back to the constant temperature water tank 50 through the sixth pipe 66 for heating. Then it is pumped out through the first pipe 61, thereby realizing the circulation of the high temperature medium.
[0060] In some embodiments, along the axial direction of the filling cylinder 30, the height of the third port of the filling nozzle 90 is lower than the height of the fourth port of the filling nozzle 90, so that the flow direction of the high-temperature medium in the filling nozzle 90 is opposite to the flow direction of the object to be filled in the filling nozzle 90, thereby improving heat exchange efficiency and preventing the object to be filled from clogging the filling nozzle 90.
[0061] In some embodiments, to facilitate the placement and fixing of the filling bottles, the workbench 10 is also provided with a receiving platform 13, which is located directly below the filling nozzle 90; in other embodiments, a fixing module can also be provided on the receiving platform 13 to fix the filling bottles.
[0062] In some embodiments, to further improve the heating efficiency and temperature uniformity of the object to be filled, the constant temperature filling mechanism further includes a support 12 and a stirring assembly 40. The support 12 is connected to the worktable 10. The stirring assembly 40 is located on the support 12 and includes a stirring motor 41 and a stirring paddle 42. The stirring paddle 42 is connected to the output end of the stirring motor 41. At least a portion of the stirring paddle 42 extends into the filling cylinder 30 along the axial direction of the filling cylinder 30. By stirring the object to be filled with the stirring paddle 42, the heat exchange efficiency between the object to be filled and the inner cylinder 32 can be improved, making the heating temperature of the object to be filled more uniform.
[0063] In some embodiments, the constant temperature filling mechanism further includes a control valve 21, wherein the control valve 21 and the guide cylinder 35 are used to control the opening and closing of the guide cylinder 35; and the discharge valve 84 is used to control the opening and closing of the discharge pipe and the filling nozzle 90.
[0064] In some embodiments, the constant temperature filling mechanism also includes a control box 70, which is located on the side wall of the workbench 10. The control box 70 is equipped with a controller, which is configured to control the opening and closing of the feeding valve 84 and the control valve 21. The controller's control of the valve body's opening and closing is existing technology and will not be described in detail. In addition, the rotation speed of the circulating pump, the temperature of the heating rod, and the stirring speed of the stirring motor 41 are also controlled by the controller, which are also conventional technical means in the field and will not be described in detail.
[0065] In some embodiments, the filling cylinder 30, the discharge pipe, and the filling nozzle 90 may also be equipped with temperature sensors to detect the temperature of each part in real time. The temperature sensors are connected to a controller, which is configured to adjust the flow rate of the circulating pump and the heating temperature of the heating rod based on the data fed back by the temperature sensors, so as to ensure that the temperature of the object to be filled is within the set range.
[0066] The working process of this utility model is as follows: Please refer to... Figures 1-6 The heat exchange medium (water or heat transfer oil) is heated by a heating rod in a constant temperature water tank 50 to form a high-temperature medium, which is then pumped to the first pipe 61 by a circulating pump. The high-temperature medium enters the heat transfer pipe 33 to heat the entire filling cylinder 30. The object to be filled inside the filling cylinder 30 exchanges heat with the inner wall of the filling cylinder 30, thereby achieving temperature rise. During this process, the stirring motor 41 simultaneously drives the stirring paddle 42 to rotate and stir the object to be filled, further improving the heat exchange efficiency. The high-temperature medium in the heat transfer pipe 33 enters the third chamber 83 through the second pipe 62, exchanges heat with the discharge pipe, and then flows to the third pipe 63. Inside the second chamber 22, the high-temperature medium can further exchange heat with the guide cylinder 35, thereby ensuring that the object to be filled will not solidify and cause blockage as it passes through the guide cylinder 35 and the discharge pipe. The high-temperature medium in the second chamber 22 enters the filling nozzle 90 through the fourth pipe 64, heats the filling nozzle 90, and then enters the first chamber 111 through the fifth pipe 65 for storage. Finally, it flows back to the constant temperature water tank 50 through the sixth pipe 66 for reheating. This continuous circulation ensures that the temperature of the object to be filled remains stable throughout the filling process, preventing solidification and blockage, thereby improving filling efficiency.
[0067] In summary, this utility model embodiment provides a constant temperature filling mechanism, which, by setting a constant temperature pipeline system 60, can sequentially connect the heat conduction pipe 33, the feeding component 80, the second chamber 22, the first chamber 111, and the constant temperature water tank 50 to form a circulation loop. This allows the liquid in the constant temperature water tank 50 to circulate and heat the filling cylinder 30 and the feeding component 80, ensuring that the cosmetic emulsion or paste remains in a molten state during the filling process, thereby improving filling efficiency.
