[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0029] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0030] As attached Figure 1-7 The illustrated sanitary oil melting machine includes a housing 1, which contains multiple oil melting devices; the multiple oil melting devices can work simultaneously to provide oil melting efficiency.
[0031] The oil melting device includes a lifting assembly, a stirring assembly, a heating coil 4, a material extraction pipe 5, and a tray 6; it also includes a controller 7, to which the lifting assembly, stirring assembly, and heating coil 4 are electrically connected. The controller 7 causes each assembly to operate in the sequence required by the process settings. The tray 6 supports the oil drum 10, which is filled with solid petroleum jelly. The controller 7 is a PLC controller or a computer.
[0032] The extraction pipe 5 includes an upper pipe 51 and a lower pipe 52, which are connected by a flange 53. A filter screen 54 is detachably installed between the upper pipe 51 and the lower pipe 52. By installing the filter screen 54, impurities in the petroleum jelly can be filtered out, preventing them from entering the next process. At the same time, the filter screen 54 overlaps the upper end of the lower pipe 52, allowing for quick disassembly and maintenance.
[0033] The heating coil 4 includes an inlet 41 and an outlet 42. During heating, hot water or steam can be introduced into the inlet 41 so that the heat from the hot water or steam is conducted to the petroleum jelly in the oil drum 10 through the heating coil 4, reducing the evaporation of petroleum jelly exposed to air during heating, thereby reducing the melting loss of petroleum jelly.
[0034] The stirring assembly includes a stirring motor 31, which is fixed to the top of the housing 1. The output end of the stirring motor 31 is connected to an output shaft 32. The output shaft 32 has stirring blades 33 distributed circumferentially. The output shaft 32 and the stirring blades 33 can extend into the oil tank 10 and fully stir the petroleum jelly inside the oil tank 10, accelerating the melting of the petroleum jelly, thereby shortening the running time and improving production efficiency.
[0035] The lifting assembly includes a lifting motor 21 and a lead screw 22 connected to the output end of the lifting motor 21. A slider 23 is threadedly connected to the lead screw 22, and the slider 23 is fixedly connected to the tray 6. The slider 23 is slidably connected to the housing 1. The support column of the housing 1 restricts the rotation of the slider 23, allowing it to move smoothly vertically along the lead screw 22. The lifting motor 21 drives the lead screw 22 to rotate, and the lead screw 22 causes the slider 23 to slide along the height of the housing 1, thereby mechanically lifting the tray 6 on the housing.
[0036] In some embodiments, the present invention further includes a stabilizing component to maintain the stability of the pallet during lifting. The stabilizing component includes a belt 81, which is a non-closed-loop belt. A tensioning frame 61 is provided on the side of the pallet 6 near the lead screw 22. A tensioning wheel 62 is rotatably mounted on the tensioning frame 61. Both ends of the belt 81 extend outward from the belt body direction and are respectively provided with a first tongue 811 and a second tongue 812. The first tongue 811 of the belt 81 is fixed to the upper end of the housing 1 by a belt pressure plate 82 and bolts. The second tongue 812 of the belt 81 surrounds the tensioning wheel 62 and is fixed to the lower end of the housing 1 by a belt baffle 83 and bolts. The tensioning wheel 62 is slidably connected to the belt 81. Because the belt 81 is elastic, during the melting of Vaseline, when the oil drum 10 undergoes slight deformation due to the change in center of gravity, the belt 81 will generate corresponding elastic force to balance the effect of the change in center of gravity, effectively improving the unstable pressure of the pallet 6 on the lead screw 22, thereby ensuring that the pallet 6 runs smoothly and with low noise.
[0037] In some embodiments, the heating coil 4 is fixedly connected to the housing 1, and the heating coil 4 is sleeved on the outside of the output shaft 32.
[0038] In some embodiments, the outer wall of the housing 1 is connected to an insulation layer 9, and an observation window 91 is provided on the insulation layer 9. The insulation layer 9 can effectively reduce heat loss and prevent the vaporized petroleum jelly from leaking out. At the same time, the temperature of the housing 1 can also play a heating role, which improves production efficiency and overcomes the shortcomings of the past, such as long melting time and high operating temperature.
[0039] In some embodiments, a drain pipe 11 is fixedly connected to the middle of the housing 1, and the drain pipe 11 is connected to the material extraction pipe 5 during cleaning.
[0040] In some embodiments, the side wall of the tray 6 is provided with a limiting strip 63, which positions the oil drum 10 to ensure that the oil drum 10 is placed coaxially with the output shaft 32.
[0041] The working principle of this utility model is as follows:
[0042] First, the oil drum 10 containing petroleum jelly is placed on the tray 6 inside the housing 1. The tray 6 moves the oil drum 10 upward via a lifting assembly. Above the oil drum 10 are heating coils 4 and a stirring assembly. When the oil drum 10 rises to the point where part of the heating coil 4 enters the oil drum 10, the lifting assembly maintains its current position, and the heating coil 4 automatically receives hot water or steam to heat the petroleum jelly. Simultaneously, the stirring assembly starts to accelerate the melting of the petroleum jelly. After the oil drum 10 has been heated to the set time by the controller 7, one end of the extraction pipe 5 is connected to a suction pump, and finally, the petroleum jelly in the oil drum 10 is drawn into the sterilization tank through the extraction pipe 5. After the discharge is completed, the lifting assembly drives the tray 6 to automatically descend, moving the oil drum 10 to the bottom of the housing 1 for the next use. All operating procedures are completed by the controller 7.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
