Description

Technical Field

[0001] This utility model relates to an improved sealing mechanism for automatic medicine packaging, and more particularly to an automatic medicine packaging sealing mechanism that can simultaneously create an opening at the edge of each package during the automatic medicine packaging process, so as to facilitate tearing open a medicine dispensing opening. Background Technology

[0002] Taiwan Patent Publication No. M332634 discloses an improved structure for an automatic pharmaceutical dispensing machine. It utilizes pre-set recessed compartments on a dispensing tray to hold pre-measured quantities of pharmaceuticals. A dispensing bag drive mechanism drives a series of dispensing bags through a sealing mechanism, allowing each pre-measured quantity of pharmaceutical to fall into the continuous dispensing bag one by one. The sealing mechanism uses a movable sealing head with perforated teeth to press against an elastic pressure seat. Heating the continuous dispensing bags with the sealing head creates continuous adhesive portions, forming multiple equally spaced dispensing bags for holding pharmaceuticals. The perforated teeth create easily tearable perforations in the adhesive portions between the dispensing bags, facilitating the tearing of each bag.

[0003] However, due to the special characteristics of pharmaceuticals compared to general food, pharmaceutical packaging bags must possess properties such as safety, moisture resistance, and environmental friendliness to effectively contain and preserve pharmaceuticals. Early traditional continuous packaging bags were mostly made of paper, cellophane, or coated paper (glassine paper). Although these materials are environmentally friendly and easy to tear, they have shortcomings such as poor moisture resistance or easy breakage during use, and there is still a need for improvement.

[0004] Recently, aluminum foil or thin non-woven fabric has been increasingly used to make medicine packaging bags. Taking advantage of their better moisture-proof and light-blocking properties, they can provide more effective protection for medicines. However, because the above materials have excellent toughness, they are not easy to tear by hand. Therefore, the perforated lines formed by the perforated lines can easily tear the continuous package containing each quantitative medicine into small packages with a single dose. However, in practical applications, the small packages after tearing still have shortcomings such as being difficult to tear open to form an opening (for dispensing medicine), causing inconvenience and trouble when taking medicine.

[0005] In view of the aforementioned shortcomings of conventional automatic pharmaceutical dispensing machines in practical applications, the inventor researched and improved upon these shortcomings, and finally this utility model was created. Utility Model Content

[0006] The main objective of this invention is to provide an improved sealing mechanism for automatic drug packaging. This sealing mechanism comprises a compressible, elastic pressure seat, a movable sealing head with heating function, and a side blade. The pressure seat and sealing head are positioned on opposite sides of the unfolding and moving path of a continuous packaging bag. The sealing head has a continuous sealing section, a separating sealing section, and perforated teeth. The side blade is positioned on the sealing head and has a shape that aligns with the unfolding and moving path of the continuous packaging bag. The blade has an intersecting cutting edge. When the sealing head is pressed against the pressure seat and the continuous packaging bag is heated, a continuous adhesive portion can be formed on the continuous packaging bag, and multiple packaging bags can be separated by the adhesive portion. The perforated teeth can form an easy-to-tear perforation on the adhesive portion between each packaging bag, and the cutting edge of the side blade can form a cut on the adhesive portion at the edge of each packaging bag. Utilizing the easy-to-tear characteristic of the cut, the edge of each packaging bag can be easily torn along the cut to create a medicine dispensing opening, thereby achieving the effect of convenient opening and taking medicine.

[0007] Another objective of this invention is to provide an improved sealing mechanism for automatic medicine packaging, wherein the sealing head has a groove on the side adjacent to the toothed edge of the hole for receiving the side blade, and positioning holes are provided on both sides of the groove for fixing a blade bracket by combining multiple positioning elements.

The perforated line can form an easy-to-tear and separate perforation line on each dividing sealing edge of each adhesive portion, while the cutting edge of the side blade can form an easy-to-tear slit on the continuous sealing edge of each sub-bag.

[0009] According to the above structure, at least one of the directions of the perforated teeth and the cutting edge of the side blade intersects perpendicularly with the direction of the unfolding and moving path of the continuous sub-bag.

[0010] According to the above structure, the side blade is installed on a continuous sealing section adjacent to the partition sealing section.

[0011] According to the above structure, the sealing head has a groove on the side adjacent to the toothed hole to accommodate the side blade.

[0012] According to the above structure, the groove is provided with positioning holes on both sides, which can be used to fix a blade bracket by combining multiple positioning elements, and the blade bracket can be used to clamp and position the side blade.

[0013] According to the above structure, the sealing head is disposed on a sealing shell seat, a cover plate that can be movably closed is pivotally connected to one side of the sealing shell seat, and the pressure bearing seat is disposed on the cover plate.

[0014] According to the above structure, one side edge of the cover plate is provided with tear teeth perpendicular to the unfolding and moving path of the continuous package bag.

[0015] According to the above structure, the sealing head has a heating function, which can heat the continuous sub-bags and form the adhesive part.

Detailed Implementation

[0024] Please see Figure 1 and Figure 2 As shown, the main structure of this utility model includes: a sealing mechanism 1 attached to a pre-set packaging machine A; wherein the packaging machine A has a housing 3 capable of receiving a rolled-up continuous packaging bag 2, a dispensing tray 4 is provided on the top of the housing 3, and a plurality of receiving recesses 41 for holding a quantitative amount of medicine B are provided on the dispensing tray 4, and a movable bottom plate is provided on the bottom side of each receiving recess 41, and each movable bottom plate can be opened above a medicine funnel 42 as the dispensing tray 4 rotates, so that the medicine B in each receiving recess 41 can fall downward through the medicine funnel 42.

[0025] The housing 3 is equipped with a drive mechanism 31 and a support 32. The drive mechanism 31 has a drive motor 311, which can drive a pivot 313, a dispensing tray shaft 314 and a support shaft 321 via a gear set 312. The pivot 313 drives a bag dispensing drive mechanism 33 to extend one end of the continuous bag 2 outward. The dispensing tray shaft 314 can drive the dispensing tray 4 to rotate. The support shaft 321 can extend and retract through the support 32, and a return spring 322 is connected to one end of the support shaft 321.

[0026] The sealing mechanism 1 consists of a pressure seat 11, a sealing head 12 with heating function, and a blade 13 on one side. The pressure seat 11 and the sealing head 12 are located on opposite sides of the unfolding and moving path of the continuous sub-bag 2. The sealing head 12 is connected to the end of the support shaft 321 away from the return spring 322, so that the sealing head 12 can reciprocate toward the pressure seat 11 due to the linkage of the support shaft 321. The sealing head 12 is provided with a continuous sealing part 12a, a partition sealing part 12b, and a perforated tooth 121 that intersects (preferably perpendicular to) the unfolding and moving path of the continuous sub-bag 2.

[0027] The side blade 13 is disposed on the sealing head 12, and the side blade 13 has a cutting edge 131 that intersects the unfolding and moving path of the continuous package bag 2. In this embodiment, the sealing head 12 is provided with a groove 122 on the side adjacent to the perforated tooth 121 to accommodate the side blade 13. The groove 122 is provided with positioning holes 123 on both sides, which can be used to fix a blade bracket 124 by combining multiple positioning members 125, and the side blade 13 is clamped and positioned by the blade bracket 124.

[0028] In one feasible embodiment, the housing 3 is provided with a U-shaped sealing shell seat 14, and a cover plate 15 is pivotally mounted on the opening side of the sealing shell seat 14, so that the cover plate 15 can be closed and fixed on the opening of the sealing shell seat 14; the sealing head 12 is provided on the sealing shell seat 14, and the pressure bearing seat 11 is provided on the cover plate 15 via a plurality of return springs 111, so that the pressure bearing seat 11 maintains a movable elasticity; one side edge of the cover plate 15 is provided with tear teeth 151 perpendicular to the unfolding and moving path of the continuous packaging bag 2.

[0029] Please see Figures 3 to 5 As shown, the present invention uses the bag-driving mechanism 33 to drive one end of the continuous bag 2 to open outward and extend. When the continuous bag 2 passes under the injection funnel 42, it can receive the medicine B falling from the receiving recess 41. In the initial state, the sealing mechanism 1 has the pressure seat 11 and the sealing head 12 separated from each other (e.g., Figure 3 (As shown); then, the continuous packaging bag 2 containing the medicine B passes through the sealing mechanism 1, driven by the drive motor 311 via the gear set 312 to drive the support shaft 321, so as to press the sealing head 12 against the pressure seat 11 and heat the continuous packaging bag 2 (as shown); Figure 4 As shown), the continuous sealing portion 12a forms a continuous sealing edge 21a on the continuous sub-bag 2, and the partition sealing portion 12b forms a partition sealing edge 21b on the continuous sub-bag 2. The continuous sealing edge 21a and the partition sealing edge 21b form a continuous adhesive portion 21, and the adhesive portion 21 separates sub-bags 22 that can contain the medicine B. At the same time, the perforation teeth 121 can form a perforation 23 that is easy to tear and separate on the partition sealing edge 21b between each sub-bag 22, and the blade portion 131 of the side blade 13 can form an easy-to-tear cut 24 on the continuous sealing edge 21a at the edge of each sub-bag 22 (as shown). Figure 5 (as shown); Finally, after the drug B is packaged, the continuous packaging bag 2 can be torn apart by the tearing tooth 151 to separate the packaged (containing drug B) packaging bag 22.

[0030] When taking medication B, after the sub-bag 22 is torn open along the hole line 23, it can be directly torn open along the cut 24, so that one side of each sub-bag 22 forms a dispensing opening for medication B to be poured out, thereby improving the shortcomings of traditional sub-bags 22 which are not easy to tear open.

[0031] In summary, the improved sealing mechanism for automatic medicine packaging of this utility model can indeed achieve the effect of simultaneously creating an opening at the edge of each package during the automatic dispensing process, so as to facilitate tearing open a dispensing opening. The above description is only an illustration of the preferred embodiment of this utility model. Any variations, modifications, alterations, or equivalent substitutions that extend from the technical means and scope of this utility model should also fall within the protection scope of this utility model patent application.
