Description

Technical Field

[0001] This utility model relates to the field of industrial filling equipment, specifically to a filling funnel with a porous structure. Background Technology

[0002] Automated filling equipment is a type of automated filling equipment. Its core function is to replace traditional manual filling to improve production efficiency, ensure filling accuracy and product quality stability. It is widely used in packaging production lines in the food, pharmaceutical, and chemical industries.

[0003] In the industrial filling field, funnels are sometimes needed. The large opening at the top of a traditional funnel can reduce the accuracy of filling alignment. However, when the funnel is inserted into the opening at the top of the container, if a large flow of filling is carried out and the funnel tightly blocks the container opening, the air inside the originally hollow container will not be able to escape quickly. This will reduce the filling efficiency and easily cause droplets to splash. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a filling funnel with a porous structure.

[0005] To solve the above problems, this utility model provides a filling funnel with a porous structure. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: A porous filling funnel includes: a funnel cone portion; a guide tube communicating with the bottom of the funnel cone portion, the guide tube comprising, from bottom to top, a first cylindrical section, an inclined frustum section, a second cylindrical section, and a third cylindrical section, wherein the outer diameter of the first cylindrical section is smaller than the outer diameter of the second cylindrical section, the outer diameter of the third cylindrical section is smaller than the outer diameter of the second cylindrical section, and the outer diameters at both ends of the inclined frustum section are equal to the outer diameters of the first cylindrical section and the second cylindrical section, respectively; a through hole axially penetrating the inclined frustum section and the second cylindrical section; wherein, from the axial perspective of the guide tube, the cross-sectional profile of the outer wall of the second cylindrical section and the cross-sectional profile of the outer wall of the first cylindrical section are two inscribed circles.

[0006] As a further improvement of this utility model, from the axial perspective of the guide tube, the cross-sectional outlines of the outer walls of the first cylindrical segment and the third cylindrical segment are mutually overlapping circles.

[0007] As a further improvement of this utility model, there are two through holes, one of which is an exhaust hole and the other is a sampling hole.

[0008] As a further improvement of this utility model, a stepped surface perpendicular to the axis of the guide tube is formed at the junction of the inclined frustum section and the second cylindrical section, and the two ends of the through hole are a circular hole and an elliptical hole, respectively.

[0009] As a further improvement of this utility model, the guide tube has a pipe cavity with a uniform inner diameter, the inner diameter of the through hole is smaller than the inner diameter of the pipe cavity, and the pipe cavity and the through hole are parallel to each other and do not communicate with each other.

[0010] As a further improvement of this utility model, the projection of the through hole along the axial direction does not intersect with the funnel cone.

[0011] As a further improvement of this utility model, the funnel cone portion has an oblique frustum cavity inside. From the axial perspective of the guide tube, the cross-sectional profiles of the outer walls of the funnel cone portion and the third cylindrical segment are two inscribed circles. From the axial perspective of the guide tube, the tangent points formed by the cross-sectional profiles of the outer walls of the funnel cone portion and the third cylindrical segment are symmetrically distributed on both sides of the guide tube axis with the tangent points formed by the cross-sectional profiles of the outer walls of the second cylindrical segment and the third cylindrical segment.

[0012] As a further improvement of this utility model, the first cylindrical segment is inserted into the mouth of the container, the outer diameter of the first cylindrical segment is smaller than the inner diameter of the mouth, and the outer diameter of the second cylindrical segment is larger than the inner diameter of the mouth.

[0013] As a further improvement of this utility model, the junction of the outer walls of the first cylindrical segment and the inclined frustum segment is transitioned by an inner rounded corner, and the junction of the outer walls of the second cylindrical segment and the inclined frustum segment is transitioned by an outer rounded corner.

[0014] As a further improvement of this utility model, the end of the funnel cone facing away from the guide tube is provided with a handle, which extends radially.

[0015] The beneficial technical effects of using the porous structure of the filling funnel in this application are: The filling funnel, by setting a through hole that runs through the axially inclined frustum section and the second cylindrical section, can connect the inside and outside of the container when the funnel is inserted into the container opening for filling. This allows for the timely discharge of air trapped inside the container, avoiding a decrease in filling efficiency due to the inability of air to be discharged smoothly. At the same time, it reduces the splashing of liquid droplets and ensures a stable filling process.

[0016] The guide tube adopts a segmented variable diameter structure consisting of a first cylindrical section, an inclined frustum section, a second cylindrical section, and a third cylindrical section. This design allows the inclined frustum section to provide effective support to the container opening when the funnel is inserted, preventing the funnel from shifting and maintaining stability without additional fixing.

[0017] From the perspective of the axial direction of the guide tube, the cross-sectional profiles of the outer walls of the second cylindrical section and the first cylindrical section are inscribed circles. This structure makes the transition between each section of the guide tube compact and reasonable. The thicker section of the guide tube is in a state of offset expansion to one side, which provides suitable space for the arrangement of the through holes, ensuring that the through holes can play an effective role and do not affect the normal guiding function of the guide tube.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, please refer to Figures 1 to 5 A porous filling funnel includes: a funnel cone portion 5; a guide tube communicating with the bottom of the funnel cone portion 5, the guide tube comprising, from bottom to top, a first cylindrical section 1, an inclined frustum section 2, a second cylindrical section 3, and a third cylindrical section 4, wherein the outer diameter of the first cylindrical section 1 is smaller than the outer diameter of the second cylindrical section 3, the outer diameter of the third cylindrical section 4 is smaller than the outer diameter of the second cylindrical section 3, and the outer diameters at both ends of the inclined frustum section 2 are equal to the outer diameters of the first cylindrical section 1 and the second cylindrical section 3, respectively; and a through hole 8 axially penetrating the inclined frustum section 2 and the second cylindrical section 3. Wherein, from an axial perspective along the guide tube, the cross-sectional profile of the outer wall of the second cylindrical section 3 and the cross-sectional profile of the outer wall of the first cylindrical section 1 are two inscribed circles.

[0022] From bottom to top, the lateral dimensions of the truncated cone section 2 and the funnel cone section 5 gradually increase.

[0023] Figure 5 The application diagram is in Figure 4 Based on, Figure 5The diagram illustrates container 10. In actual use, the funnel is inserted into the opening 1001 of container 10. Due to the change in outer diameter, the truncated cone section 2 will eventually be stuck on the opening 1001, meaning the outer diameter of the truncated cone section 2 is equal to the inner diameter of the opening 1001. At this point, one end of the through hole 8 is inside container 10, and the other end is outside. When liquid is poured into the cone section 5 of the funnel, the liquid flows into container 10 through the guide tube, allowing the gas inside container 10 to exit through the through hole 8.

[0024] The beneficial effects of adopting the above technical solution are as follows: By setting a through hole 8 that runs through the axially through the inclined frustum section 2 and the second cylindrical section 3, the inside and outside of the container can be connected during filling, allowing for timely discharge of trapped air inside the container, improving filling efficiency and reducing droplet splashing. Simultaneously, the guide tube adopts a segmented variable diameter structure of the first cylindrical section 1, the inclined frustum section 2, the second cylindrical section 3, and the third cylindrical section 4, ensuring that the funnel can be stably secured to the container opening, preventing displacement and eliminating the need for additional fixing.

[0025] In some other embodiments of this utility model, from the axial perspective of the guide tube, the cross-sectional outlines of the outer walls of the first cylindrical segment 1 and the third cylindrical segment 4 are mutually overlapping circles.

[0026] The beneficial effect of adopting the above technical solution is that it facilitates processing and manufacturing.

[0027] In some other embodiments of this utility model, there are two through holes 8, one of which is an exhaust hole and the other is a sampling hole.

[0028] The beneficial effects of adopting the above technical solution are: serving as both an exhaust port and a sampling port, it not only solves the problem of venting inside the container during the filling process, but also facilitates sampling and testing at any time, enhancing the multifunctionality and ease of operation of the funnel.

[0029] like Figure 1 , Figure 2 As shown, in some other embodiments of this utility model, a stepped surface 9 perpendicular to the axis of the guide tube is formed at the junction of the truncated cone section 2 and the second cylindrical section 3, and the two ends of the through hole 8 are a circular hole 801 and an elliptical hole 802, respectively.

[0030] like Figure 4 As shown, in some other embodiments of this utility model, the inside of the guide tube is a pipe cavity 7 with a uniform inner diameter, the inner diameter of the through hole 8 is smaller than the inner diameter of the pipe cavity 7, and the pipe cavity 7 and the through hole 8 are parallel to each other and do not communicate with each other.

[0031] Liquid flows through pipe cavity 7.

[0032] The first cylindrical segment 1 and the second cylindrical segment 3 are arranged off-axis, that is, the axes of the first cylindrical segment 1 and the second cylindrical segment 3 are parallel and do not coincide. The axis of the pipe cavity 7 coincides with the axis of the first cylindrical segment 1, so that the pipe cavity 7 forms a wall thickness of unequal thickness in the second cylindrical segment 3. The through hole 8 is arranged in the relatively thick wall, so that there is room for arrangement.

[0033] The beneficial effects of adopting the above technical solution are: the inner diameter of the internal pipe cavity 7 of the guide pipe is uniform, ensuring smooth liquid flow. The inner diameter of the through hole 8 is small and parallel to the pipe cavity 7, preventing liquid from seeping into the through hole while maintaining structural strength.

[0034] In some other embodiments of this utility model, the projection of the through hole 8 along the axial direction does not intersect with the funnel cone portion 5.

[0035] The beneficial effect of adopting the above technical solution is that the through hole 8 does not intersect with the funnel cone 5 along the axial projection, which provides an operable axial space for sampling flow.

[0036] In some other embodiments of this utility model, the funnel cone portion 5 has an oblique frustum cavity 501 inside. From the axial perspective of the guide tube, the cross-sectional profiles of the outer walls of the funnel cone portion 5 and the third cylindrical segment 4 are each two inscribed circles. From the axial perspective of the guide tube, the tangent points formed by the cross-sectional profiles of the outer walls of the funnel cone portion 5 and the third cylindrical segment 4, and the tangent points formed by the cross-sectional profiles of the outer walls of the second cylindrical segment 3 and the third cylindrical segment 4, are symmetrically distributed on both sides of the guide tube axis.

[0037] The beneficial effects of adopting the above technical solution are: the radial offset direction of the funnel cone 5 is determined to be opposite to the radial offset direction of the thickened section of the guide tube, so the axial space between the two is separated, which facilitates smooth sampling and smooth exhaust.

[0038] like Figure 5 As shown, in some other embodiments of this utility model, the first cylindrical segment 1 is inserted into the opening 1001 of the container 10, the outer diameter of the first cylindrical segment 1 is smaller than the inner diameter of the opening 1001, and the outer diameter of the second cylindrical segment 3 is larger than the inner diameter of the opening 1001.

[0039] The beneficial effects of adopting the above technical solution are: ensuring that the funnel is firmly locked in place, preventing it from falling off, and providing an effective venting space for the through hole 8.

[0040] In some other embodiments of this utility model, the junction of the outer walls of the first cylindrical segment 1 and the inclined frustum segment 2 is transitioned by an inner rounded corner, and the junction of the outer walls of the second cylindrical segment 3 and the inclined frustum segment 2 is transitioned by an outer rounded corner.

[0041] The beneficial effect of adopting the above technical solution is to reduce stress concentration.

[0042] In some other embodiments of this utility model, the end of the funnel cone 5 facing away from the guide tube is provided with a handle 6, which extends radially.

[0043] The beneficial effects of adopting the above technical solution are: the handle 6 makes it easy for users to hold and operate, improving the convenience of use and making it suitable for filling scenarios.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
