[0022] Please see Figure 1 , Figure 2 and Figure 3 This application provides an example of a fixture for supporting an essential oil tube to be plastic-sealed. The fixture 20 includes a base 21 and a positioning block 22. The positioning block 22 has a bottom surface 221 and a positioning surface 222 located above the bottom surface 221. The bottom surface 221 of the positioning block 22 is disposed on the base 21, and the positioning surface 222 is used to support the plastic-sealing film 40. The positioning block 22 has a groove 224 for accommodating the essential oil tube 30. The upper end of the groove 224 extends to the positioning surface 222, and the lower end of the groove 224 extends toward the bottom surface 221.

[0023] The base 21 can be used to support the positioning block 22. In this example, the base 21 can be fixedly or detachably mounted on the work platform. In this example, the bottom wall or at least one side of the base 21 can be fixedly or detachably mounted on the work platform.

[0024] The positioning block 22 is mounted on the base 21. In this example, the positioning block 22 can be fixedly or detachably mounted on the base 21, which can serve as an intermediate connector between the positioning block 22 and the work platform. The positioning block 22 has a bottom surface 221, which is the bottom surface of the positioning block 22 facing the ground. Optionally, the bottom surface 221 can be parallel to the horizontal plane. Optionally, the bottom surface 221 can be used to assemble on the base 21. Optionally, the base 21 can have at least one upper surface facing directly above or diagonally above the base 21, one of which is a mounting surface 212. The bottom surface 221 of the positioning block 22 can be mounted on the mounting surface 212. The bottom surface 221 can be placed directly on the mounting surface 212, or it can be fixedly or detachably connected to the mounting surface 212. The positioning block 22 has a positioning surface 222, which is located above the bottom surface 221. This means that the minimum height of the positioning surface 222 from the ground is greater than the minimum height of the bottom surface 221 from the ground in the vertical direction. In this application example, the positioning surface 222 can be located directly above or diagonally above the bottom surface 221.

[0025] The positioning surface 222 is used to support the sealing film 40, meaning that the sealing film 40 can be placed on the positioning surface 222. In this example, the sealing film 40 is used to adhere to the end of the essential oil tube. When the sealing film 40 is heated, the heat-melted sealing film 40 can adhere to the end of the essential oil tube 30 to seal that end of the essential oil tube 30. The sealing film 40 can be a material that can heat-melt under heating conditions. In this example, the sealing film 40 can be placed directly on the positioning surface 222. For example, the sealing film 40 can be placed horizontally or at a certain angle to the horizontal plane on the positioning surface 222. Optionally, the sealing film 40 can also be fixed on the positioning surface 222. For example, the sealing film 40 can be fixed to a preset position on the positioning surface 222 by snap-fit, pin-fit, screw connection or other means. In some examples, a first positioning part 226 can be provided on the positioning surface 222, and the sealing film 40 can be mutually positioned with the first positioning part 226 on the positioning surface 222. Optionally, a second positioning part 41 can be provided on the plastic sealant 40. The plastic sealant 40 can be placed at a preset position on the positioning surface 222 by positioning the second positioning part 41 and the first positioning part 226 with each other. In some examples, the plastic sealant 40 is provided with a dividing line 42, which divides the preset part on the plastic sealant 40 into a preset shape. For example, the area of ​​the dividing line 42 can form a heat-melting area 43 on the plastic sealant 40. The heat-melting area 43 can be a polygonal area, or it can be a circular or irregular area. When the second positioning part 41 on the plastic sealant 40 is aligned with the first positioning part 226 on the positioning surface 222, the heat-melting area 43 formed by the dividing line 42 corresponds to the position of the tray 224. When the heat-melting area 43 formed by the dividing line 42 of the plastic sealant 40 is heat-melted, the plastic sealant 40 in the heat-melting area 43 can be more easily detached from the plastic sealant 40, thereby reducing the adhesion between the plastic sealant 40 and the essential oil tube 30.

[0026] In this example, there can be one or more positioning surfaces 222. When multiple positioning surfaces 222 are used, they can be set at intervals.

[0027] The positioning block 22 is provided with a groove 224 for accommodating the essential oil tube 30. Accommodating the essential oil tube 30 means that the essential oil tube 30 can be installed in the groove 224 so that the essential oil tube 30 can be confined to a preset position on the positioning block 22. The upper end of the groove 224 extends to the positioning surface 222, and the lower end of the groove 224 extends towards the bottom surface 221, so that the groove 224 extends vertically as a whole. The essential oil tube 30 can be inserted into the groove 224. When one end of the essential oil tube 30 is placed in the position of the positioning surface 222, a plastic sealing film 40 can be placed on the positioning surface 222. The plastic sealing film 40 is heated by a heating device so that when the plastic sealing film 40 is heat-melted, it can heat-seal one end of the essential oil tube 30. In this example, the groove 224 can be a recessed groove formed on one of the surfaces of the positioning block 22, or the groove 224 can be a recessed groove or a through groove extending into the positioning block 22.

[0028] When heat sealing the essential oil tube 30 is required, the positioning tube can be installed in the bracket 224 first, with one end of the positioning tube positioned at a positioning surface 222. The sealing film 40 is then placed on the positioning surface 222, and the sealing film 40 is heated using a heating device to heat seal that end of the essential oil tube 30. After heat sealing one end of the essential oil tube 30, essential oil can be injected into the essential oil tube 30 through the other end, and then the other end of the essential oil tube 30 can be heat sealed according to the above procedure. Taking the positioning block 22 having a positioning surface 222 as an example, after completing the heat sealing of one end of the essential oil tube 30, the essential oil tube 30 can be completely removed, essential oil can be injected through the other end of the essential oil tube 30, and then the essential oil tube 30 can be placed into the tray 224 so that the other end of the essential oil tube 30 is located at the positioning surface 222. Then the sealing film 40 is placed on the positioning surface 222, and the other end of the essential oil tube 30 is heat sealed by the heating device.

[0029] In this example, the essential oil tube 30 is positioned and fixed by using the groove 224 on the positioning block 22, and by setting the positioning surface 222 that cooperates with the plastic seal 40, the plastic seal 40 can be aligned with the essential oil tube 30 in a relatively stable state, which can improve the problem of relative displacement between the essential oil tube 30 and the plastic seal 40 when the essential oil tube 30 is curved.

[0030] In some examples, the bracket 224 is an arc-shaped groove, and the curvature of the bracket 224 matches the curvature of the essential oil tube 30. By using an arc-shaped bracket 224, the bracket 224 can better adapt to the curvature of the essential oil tube 30. When the essential oil tube 30 is installed in the bracket 224, the stability of the essential oil tube 30 can be improved, further reducing the possibility of unnecessary displacement of the essential oil tube 30 relative to the positioning block 22.

[0031] In some examples, the positioning block 22 has at least two positioning surfaces 222, defined as a first surface and a second surface. The positioning block 22 is provided with a first groove 224 and a second groove 224 corresponding to the first surface and the second surface, respectively. One end of the first groove 224 extends to the first surface and the other end extends towards the bottom surface 221. One end of the second groove 224 extends to the second surface and the other end connects to the other end of the first groove 224, so that the first groove 224 and the second groove 224 are interconnected to form a whole. The first groove 224 and the second groove 224 can form a generally U-shaped channel into which an essential oil tube 30 can be placed. One end of the essential oil tube 30 is located on the first surface and the other end is located on the second surface. A sealing film 40 can be provided on the first surface and the second surface to heat seal both ends of the essential oil tube 30 from the first surface and the second surface, respectively.

[0032] In some examples, the positioning surface 222 is set horizontally, so that when the plastic sealant 40 is placed on the positioning surface 222, the plastic sealant 40 is not easy to fall off the positioning surface 222. On the one hand, this can improve the stability of the plastic sealant 40, and on the other hand, it can facilitate the alignment of the plastic sealant 40 with the tray 224.

[0033] In some examples, there are multiple trays 224, with at least two trays 224 arranged parallel to each other. By providing multiple trays 224, multiple essential oil tubes 30 can be placed on the positioning block 22 simultaneously, thereby improving the sealing efficiency of the essential oil tubes 30. "At least two trays 224 arranged parallel to each other" means that at least two trays 224 are both arc-shaped or straight, and are arranged parallel to each other, allowing for the simultaneous placement of two essential oil tubes 30.

[0034] In some examples, at least the positioning surface 222 is made of stainless steel, which can reduce deformation of the positioning surface 222 during the thermoforming process. In this example, the positioning block 22 can be made entirely of stainless steel, or only the positioning surface 222 of the positioning block 22 can be made of stainless steel.

[0035] Please refer to the following: Figure 3 , Figure 4 as well as Figure 5 In some examples, the positioning block 22 has a support surface 223, the upper end of the support surface 223 is connected to the positioning surface 222, the lower end of the support surface 223 is connected to the bottom surface 221, and the slot 224 is formed on the support surface 223. The support surface 223 is a slope or arc surface, and the support surface 223 is set towards the upper side of the positioning block 22.

[0036] The supporting surface 223 is one of the surfaces on the positioning block 22. The supporting surface 223 connects the positioning surface 222 and the bottom surface 221. Since the positioning surface 222 is located above the bottom surface 221, the supporting surface 223 is an arc-shaped or inclined surface extending along the height direction of the positioning block 22. In this example, the supporting surface 223 is defined as being positioned upwards towards the positioning block 22, meaning that the supporting surface 223 is away from the ground and forms an angle with the ground, and the supporting surface 223 is an arc-shaped or inclined surface positioned upwards towards the positioning block 22. In this example, the supporting surface 223 can serve as a transition surface between the bottom surface 221 and the positioning surface 222. The supporting surface 223 is positioned diagonally upwards towards the positioning block 22, meaning that the supporting surface 223 forms an angle with respect to the horizontal plane, and the supporting surface 223 is not perpendicular to the horizontal plane. By using an upward-sloping arc or bevel to form the support surface 223, the essential oil tube 30 can be easily placed into the tray 224 from the side and above, making the position of the tray 224 more ergonomic. Furthermore, when essential oil is injected into the tube 30, the unsealed opening of the tube 30 is positioned at the positioning surface 222, facilitating observation for any leaks. Optionally, the lower end of the support surface 223 in this example can be directly or indirectly connected to the bottom surface 221. The arc surface in this example being angled to the horizontal plane means that the plane containing the upper and lower edges of the arc surface is not parallel to the horizontal plane.

[0037] The slot 224 is formed on the support surface 223, meaning that the slot 224 is a groove formed on the side surface of the support surface 223, allowing the oil tube 30 to be placed into the slot 224 from the support surface 223. By forming the slot 224 on the support surface 223, it is convenient to put the oil tube 30 on the positioning block 22, which helps to improve the thermoforming efficiency of the oil tube 30. On the other hand, it is convenient to groove from the outer surface of the positioning block 22, which can reduce the difficulty of grooving and help to improve the grooving accuracy.

[0038] In some examples, the positioning block 22 or the base 21 has a stop surface 213, which is located on the side of the support surface 223 away from the positioning surface 222. The lower end of the bracket 224 extends to the stop surface 213. The stop surface 213 is used to stop the oil tube 30 at the end away from the positioning surface 222. The upper end of the stop surface 213 is higher than the lower end of the support surface 223.

[0039] The stop surface 213 is a surface on the base 21 or positioning block 22. The stop surface 213 is not parallel to the support surface 223, so that the stop surface 213 can block the lower edge of the support surface 223, which is the edge of the support surface 223 away from the positioning surface 222. The lower end of the bracket 224 extends to the end of the support surface 223 away from the positioning surface 222, so that the lower end of the essential oil tube 30 can be inserted into the end of the support surface 223 away from the positioning surface 222. The stop surface 213 is used to stop the end of the essential oil tube 30 away from the positioning surface 222, meaning that the lower end of the essential oil tube 30 can abut against the stop surface 213.

[0040] In this example, a through groove can be formed on the supporting surface 223 to form a support groove 224 through the through groove from the self-positioning surface 222 towards the supporting surface 223, so as to facilitate grooving on the supporting surface 223. By setting the stop surface 213, the lower end of the essential oil tube 30 can be positioned to prevent the essential oil tube 30 from moving towards the bottom surface 221, thereby limiting the essential oil tube 30 so that the essential oil tube 30 can maintain a preset posture and preset position on the positioning block 22.

[0041] The upper end of the stop surface 213 is higher than the lower end of the support surface 223, so that the stop surface 213 protrudes from the lower end of the support surface 223, and the stop surface 213 can block the lower outer side of the bracket 224. Optionally, the stop surface 213 can be a surface on the base 21. In this example, the base 21 can be partially recessed or partially protruding to form the stop surface 213. Alternatively, a protrusion can be provided on the base 21, and the stop surface 213 can be formed using one surface of the protrusion. Optionally, the stop surface 213 can also be a surface on the positioning block 22. The positioning block 22 can be partially protruding to form the stop surface 213. Alternatively, a protrusion can be provided on the positioning block 22, and the stop surface 213 can be formed using one surface of the protrusion.

[0042] In some examples, the base 21 has a recessed mounting groove 211 at one end facing the positioning block 22, the positioning block 22 is at least partially installed in the mounting groove 211, and one side wall of the mounting groove 211 forms a stop surface 213.

[0043] The mounting groove 211 is a recessed groove formed on the base 21. The mounting groove 211 can be used to accommodate the positioning block 22, thereby restricting the movement of the positioning block 22 in at least one direction. The mounting groove 211 has sidewalls, one sidewall of which forms a stop surface 213. When the positioning block 22 is installed in the mounting groove 211, the stop surface 213 blocks the end of the support surface 223 away from the positioning surface 222. On the one hand, the stop surface 213 can prevent the positioning block 22 from moving out of the mounting groove 211, and on the other hand, it can prevent the end of the bracket 224 away from the positioning surface 222 from moving out. In some examples, the bottom wall of the mounting groove 211 can be the mounting surface 212 as described in any of the above examples. When the positioning block 22 is installed in the mounting groove 211, the bottom surface 221 can fit against the mounting surface 212.

[0044] In this example, the stop surface 213 can be a surface perpendicular to the horizontal plane. Optionally, the stop surface 213 can be an inclined surface set at an angle to the horizontal plane. In some examples, the stop surface 213 is set at an angle to the horizontal plane, and the stop surface 213 is an inclined surface or an arc surface set towards the upper part of the base 21, so that the stop surface 213 can be adapted to the extension direction of the lower end of the essential oil tube 30, reducing the possibility of the essential oil tube 30 tilting off the bracket 224, and helping to improve the stability of the essential oil tube 30.

[0045] In some examples, the positioning block 22 has a mating surface 225, which connects the supporting surface 223 and the bottom surface 221. The mating surface 225 is used to fit against the stop surface 213. The mating surface 225 is used to mate with the stop surface 213; mating means that the mating surface 225 can fit against the stop surface 213. Taking a concave arc surface as an example, the mating surface 225 can be a convex arc surface. The mating surface 225 connects the supporting surface 223 and the bottom surface 221. The mating surface 225 can be used to limit the movement of the positioning block 22 relative to the stop surface 213, thereby improving the stability of the positioning block 22 within the mounting groove 211.

[0046] In some examples, the support surface 223 is curved, and the curvature of the support surface 223 matches the curvature of the bracket groove 224. In this example, the curvature of the support surface 223 matches the curvature of the bracket groove 224. When the bracket groove 224 is cut on the support surface 223, the difficulty of cutting the groove can be reduced, which helps to improve the cutting accuracy of the bracket groove 224.

[0047] Please see Figure 1Based on the aforementioned fixture 20, this application also proposes an example of an essential oil tube processing device. The essential oil tube processing device includes a main body 10 and a fixture 20 as described in any of the above examples, with the fixture 20 mounted on the main body 10. The main body 10 can be a workbench or other equipment, and a working plane as described in any of the above examples can be formed on the main body 10. The fixture 20 is mounted on the main body 10, and its base 21 can be fixedly or detachably connected to the main body 10. It is understood that the main body 10 may also include other functional components for processing the essential oil tube 30, such as a heating component, a second positioning part 41, a transmission component, etc., which will not be elaborated further.

[0048] Please see Figure 2 , Figure 3 and Figure 6 This application also proposes an example of a plastic sealant 40, which can be used in any of the above examples of the jig 20 or the oil tube processing equipment. The jig 20 has a first positioning part 226 on its positioning surface 222. The plastic sealant 40 has a second positioning part 41 and a dividing line 42 spaced apart from the second positioning part. The dividing line 42 encloses and forms a hot melt zone 43. The plastic sealant 40 is installed on the positioning surface 222, and when the second positioning part 41 and the first positioning part 226 are positioned and engaged, the hot melt zone 43 and the end of the bracket 224 near the positioning surface 222 are aligned with each other.

[0049] The sealing film 40 can be in sheet form, and in this example, the thickness of the sealing film 40 can be determined according to its material. When the sealing film 40 is heated by the heating element, the heated part of the sealing film 40 can be heat-melted, and the heat-melted sealing film 40 can heat-seal the end of the essential oil tube 30.

[0050] The dividing line 42 can be a thinning area formed by a groove on the plastic seal film 40, or a weak area formed by a break line on the plastic seal film 40. The dividing line 42 encloses and forms a heat-melting area 43. When the plastic seal film 40 is subjected to external force, the dividing line 42 area can break, thereby causing the dividing area to fall off the plastic seal film 40.

[0051] A first positioning part 226 is provided on the positioning surface 222, and a second positioning part 41 is provided on the plastic sealing film 40. When the plastic sealing film 40 is installed on the positioning surface 222, the first positioning part 226 and the second positioning part 41 can be positioned and engaged with each other. The positioning and engagement includes the first positioning part 226 and the second positioning part 41 being aligned with each other, or the first positioning part 226 and the second positioning part 41 being inserted, snapped, glued, or connected in other ways. The hot melt area 43 is aligned with one end of the positioning surface 222 near the bracket 224, which means that the hot melt area 43 at least partially covers the end of the bracket 224 near the positioning surface 222. When the first positioning part 226 and the second positioning part 41 are positioned and engaged with each other, the hot melt area 43 can cover the end of the essential oil tube 30 near the positioning surface 222. When the hot melt area 43 of the plastic sealant 40 is heated by the heating device, the hot melt area 43 can be more easily detached from the plastic sealant 40 and hot melted to the end of the essential oil tube 30, thereby heat sealing the end of the essential oil tube 30.
