Description

Technical Field

[0001] This utility model relates to the field of calcium powder packaging technology, and in particular to a feeding head for calcium powder packaging. Background Technology

[0002] Calcium powder is packaged in woven bags with an inner bag. Currently, the packaging method involves securing the top of the bag to the discharge pipe using a binding mechanism before feeding. Because the inner bag is made of airtight plastic, air is difficult to expel during feeding, affecting the filling efficiency of the calcium powder. Furthermore, if the seal is not tight, calcium powder leakage can occur. This leakage not only pollutes the air but also reduces production output. Utility Model Content

[0003] This invention provides a feeding head for calcium powder packaging to overcome the shortcomings of the prior art. It facilitates air permeability during filling while ensuring air permeability, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A feeding head for packaging calcium powder is provided on the discharge pipe of a storage tank, including a feeding head installed at the lower end of the discharge pipe;

[0006] An inner tube is welded to the outer circumference of the discharge pipe. A lower ring is welded to the lower end of the inner tube. Multiple holes are opened on the lower ring. An outer conical ring is welded to the outer circumference of the lower ring. The upper end of the outer conical ring is the large end. An outer peripheral ring is provided at the upper end of the outer conical ring. The inner circumference of the outer peripheral ring and the outer circumference of the inner tube are respectively connected by threads to a connecting ring. An upper ring is welded to the upper end of the connecting ring. Multiple vent holes are opened on the upper ring. A pair of upper extension rings are welded to the upper wall of the upper ring. A filter membrane is provided inside the upper extension ring. The filter membrane is located above the vent holes.

[0007] Furthermore, the feeding pipe head has a conical structure, and the lower end of the feeding pipe head is the smaller end.

[0008] Furthermore, the outer periphery of the upper extension ring is connected to a threaded ring by a thread, and multiple pressure strips are welded to the outer periphery of the threaded ring. The lower wall of the pressure strips abuts against the upper side of the filter membrane.

[0009] Furthermore, a retaining ring is welded to the lower outer periphery of the inner tube, and there is a gap between the outer periphery of the retaining ring and the outer conical ring.

[0010] Furthermore, the inner circumference of the outer conical ring abuts against a placement ring, and the placement ring is provided with an inner conical ring. The upper end of the inner conical ring is the small end, and the inner circumference of the upper end of the inner conical ring abuts against the outer circumference of the inner tube. Multiple perforations are opened on the inner conical ring.

[0011] Furthermore, a flat plate is welded onto the discharge pipe. A pair of guide holes are respectively opened at both ends of the flat plate. A movable rod is movably installed in the guide holes. The upper end of the movable rod at the same end is connected to a movable arm by a thread. A bidirectional hydraulic cylinder is fixed on the flat plate. The two movable ends of the bidirectional hydraulic cylinder are respectively fixed to the movable arm. The lower end of the movable rod at the same end is connected to a lower extension arm by a thread. The lower extension arm is located on the lower side of the flat plate. A connecting plate is welded to the lower end of the lower extension arm. A clamping conical plate is welded to the inner end of the connecting plate. The clamping conical plate is located on the outer periphery of the outer conical ring.

[0012] The advantages of the above technical solution are:

[0013] In this invention, during calcium powder filling, the clamping conical plate can fix the packaging bag on the outer conical ring. During fixing, the clamping conical plate is moved inward by a bidirectional hydraulic cylinder to constrain and fix the upper end of the packaging bag. This fixing method can ensure that the inner wall of the packaging bag is tightly attached to the outer conical ring to prevent calcium powder from overflowing during filling.

[0014] This invention prevents dust from overflowing and polluting the environment during calcium powder filling by using holes, perforations, vents, and a filter membrane. Furthermore, the inclusion of a baffle ring, inner cone ring, and filter membrane reduces the possibility of dust drifting outwards and overflowing. Attached Figure Description

[0018] Figure 3 A cross-sectional structural diagram of one embodiment is shown. Detailed Implementation

[0019] like Figures 1-3As shown, a feeding head for calcium powder packaging is installed on the discharge pipe 1 of the storage tank. It includes a feeding head 10 installed at the lower end of the discharge pipe 1. The feeding head 10 has a conical structure and the lower end of the feeding head 10 is the small end. An inner tube 28 is welded to the outer periphery of the discharge pipe 1. A lower ring 29 is welded to the lower end of the inner tube 28. Multiple holes 30 are opened on the lower ring 29. An outer conical ring 31 is welded to the outer periphery of the lower ring 29. The upper end of the outer conical ring 31 is the large end. An outer peripheral ring 32 is provided at the upper end of the outer conical ring 31. The inner periphery of the outer peripheral ring 32 and the outer periphery of the inner tube 28 are respectively connected by a connecting ring 33 by threads. An upper ring 34 is welded to the upper end of the connecting ring 33. Multiple vent holes are opened on the upper ring 34. A pair of upper extension rings 35 are welded to the upper wall of the upper ring 34. A filter membrane 36 is provided inside the upper extension ring 35. The filter membrane 36 is located above the vent holes.

[0020] Specifically, the outer periphery of the upper extension ring 35 is connected to a threaded ring 37 by a thread, and a plurality of pressure strips 38 are welded to the outer periphery of the threaded ring 37. The lower wall of the pressure strips 38 abuts against the upper side of the filter membrane 36.

[0021] A retaining ring 39 is welded to the lower outer periphery of the inner tube 28. There is a gap between the outer periphery of the retaining ring 39 and the outer conical ring 31. The inner periphery of the outer conical ring 31 abuts against a placement ring 41. An inner conical ring 40 is provided on the placement ring 41. The upper end of the inner conical ring 40 is the small end. The inner periphery of the upper end of the inner conical ring 40 abuts against the outer periphery of the inner tube 28. Multiple through holes are provided on the inner conical ring 40.

[0022] A flat plate 2 is welded onto the discharge pipe 1. A pair of guide holes 20 are respectively opened at both ends of the flat plate 2. A movable rod 21 is movably installed in the guide holes 20. The upper end of the movable rod 21 located at the same end is connected to a movable arm 22 by a thread. A bidirectional hydraulic cylinder 24 is fixed on the flat plate 2. The two movable ends of the bidirectional hydraulic cylinder 24 are respectively fixed on the movable arm 22. The lower end of the movable rod 21 located at the same end is connected to a lower extension arm 25 by a thread. The lower extension arm 25 is located on the lower side of the flat plate 2. A connecting plate 26 is welded to the lower end of the lower extension arm 25. A clamping conical plate 27 is welded to the inner end of the connecting plate 26. The clamping conical plate 27 is located on the outer periphery of the outer conical ring 31.

[0023] In actual operation, the operator or the automatic bag feeding device transfers the packaging bag to the bottom of the feeding pipe head 10 and places the packaging bag on the feeding pipe head 10 until the outer periphery of the outer conical ring 31 abuts against the inner wall of the opening end of the packaging bag. Then, the bidirectional hydraulic cylinder 24 is activated. Driven by the bidirectional hydraulic cylinder 24, the clamping conical plate 27 moves inward and the inner wall of the clamping conical plate 27 abuts against the outer wall of the packaging bag, thus clamping the upper end of the packaging bag. Then, the opening and closing mechanism on the discharge pipe 1 of the storage tank is activated. Subsequently, calcium powder is fed into the packaging bag through the discharge pipe 1 of the storage tank and the feeding pipe head 10. During the feeding process, the air in the packaging bag is discharged outward through the holes 30, perforations, vents and filter membrane 36, while the calcium powder is blocked on the inner side of the filter membrane 36 until the filling is completed. After completion, the fixing effect of the clamping conical plate 27 on the packaging bag is removed, and the opening of the packaging bag is sealed.
