Description

Technical Field

[0001] The present invention relates to the technical field of moxa stick processing, and specifically to a rolling and extrusion device for pharmaceutical processing and its processing technology. Background Art

[0002] Medical moxa sticks are mainly used for moxibustion, which is a type of external treatment method in traditional Chinese medicine. The ignited moxa stick can help the human body warm and dredge the meridians, warm and nourish the vital energy, and regulate qi and blood. The finished moxa stick is usually cylindrical and is wrapped with cotton paper on the surface.

[0003] When processing medical moxa sticks, equipment is used to wrap the moxa sticks with paper. There are two packaging methods for moxa sticks. One is the filling type packaging, that is, the moxa stick is extruded and filled into a formed cotton paper roll. The other is to directly wrap the extruded and formed moxa stick with cotton paper. However, when the existing moxa stick paper wrapping equipment wraps the moxa stick with paper, in the case of filling type packaging, the cotton paper is easily broken. In the case of rolling packaging, it is difficult to realize the automatic paper rolling operation on the surface of the formed moxa stick, and the tightness of the paper wrapping on the surface of the formed moxa stick is not high. Summary of the Invention

[0004] To solve the above problems that when the existing moxa stick paper wrapping equipment wraps the moxa stick with paper, in the case of filling type packaging, the cotton paper is easily broken, in the case of rolling packaging, it is difficult to realize the automatic paper rolling operation on the surface of the formed moxa stick, and the tightness of the paper wrapping on the surface of the formed moxa stick is not high, the present invention is realized through the following technical solutions: A rolling and extrusion device for pharmaceutical processing, comprising:

[0048] A pharmaceutical moxa stick packaging and processing technology includes the following specific steps:

[0049] S1. First, convey the paper through the paper inlet 11 into the packaging cylinder 1;

[0050] S2. Use the suction plate 3 to hold the free end of the paper inside the packaging cylinder 1 and drive the paper to continue moving, wrapping the paper around the surface of the inner winding cylinder 2 to form a pre-rolled paper;

[0051] S3. Place the formed moxa stick 7 between the extrusion cylinder 6 and the inner winding cylinder 2, and use the extrusion cylinder 6 to push the formed moxa stick 7 into the pre-rolled paper;

[0052] S4. Continue to use the suction plate 3 to drive the paper to move and stick the paper to the surface of the formed moxa stick 7, and use the pressing plate 5 to press another layer of paper tightly on the surface of the paper conveyed by the suction plate 3;

[0053] S5. Use the glue brushing port below the glue box 9 to brush glue on the surface of the paper. After the pressing plate 5 presses the paper tightly on the surface of the formed moxa stick 7, use the inner winding cylinder 2 and the extrusion cylinder 6 to drive the formed moxa stick 7 to rotate together, and use the pressing roller 41 on the surface of the top plate 4 to bond the paper on the surface of the formed moxa stick 7 together.

[0054] Working principle of the rolling and extrusion equipment for pharmaceutical moxa stick processing:

[0055] When processing the roll paper packaging of moxa sticks, first, the conveying roller 8 and the auxiliary guide roller are used to convey the paper through the paper inlet 11 into the packaging cylinder 1. At this time, the inner roll cylinder 2 is located inside the packaging cylinder 1. The free end of the paper contacts the surface of the inner roll cylinder 2 and continues to be conveyed downward.

[0056] At this time, the driving gear 121 is driven to rotate by relevant driving equipment. The driving gear 121 drives the toothed ring 122 to slide on the surface of the packaging cylinder 1 through gear meshing with the toothed ring 122. The toothed ring 122 will drive the suction plate 3 to move together. The suction cups 31 on the surface of the suction plate 3 are used to suck the paper inside the packaging cylinder 1, and the suction plate 3 is used to drive the paper to continue moving to wrap the paper around the surface of the inner roll cylinder 2.

[0057] When the paper is wrapped around the surface of the inner roll cylinder 2, the formed moxa stick 7 is placed between the extrusion cylinder 6 and the inner roll cylinder 2 at this time. The extrusion cylinder 6 is used to push the formed moxa stick 7 in the direction of the inner roll cylinder 2 to push the formed moxa stick 7 into the formed roll paper inside the packaging cylinder 1. At this time, the suction plate 3 is still used to drive the paper to move, and the expansion and contraction of the suction cups 31 are used to stick the paper to the surface of the formed moxa stick 7.

[0058] The glue application port under the glue box 9 is used to apply glue to the surface of the paper. After the surface of the paper is applied with glue, the shear plate 10 is used to cut the paper. When the suction plate 3 drives the paper to move to the position of the pressing plate 5, the pressing plate 5 is used to press another layer of paper tightly on the surface of the paper conveyed by the suction cups 31, and the suction plate 3 is driven to move in the reverse direction to separate from the paper. At this time, the driving motor at one end of the inner roll cylinder 2 is used to drive the inner roll cylinder 2 to rotate. The inner roll cylinder 2 cooperates with the extrusion cylinder 6 to drive the formed moxa stick 7 to rotate together. Under the action of the pressing plate 5 and the pressing roller 41 on the surface of the top plate 4, the paper with glue on the surface will be bonded to the paper attached to the surface of the formed moxa stick 7. Thus, the roll paper packaging of the formed moxa stick 7 is completed.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
