Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, in particular to a four-side sealing packaging device for medical patches. Background Art

[0002] Transdermal drug delivery is a known way of administering drugs to patients; this method typically differs from injection in that the drug can penetrate the skin barrier on its own, based on its solubility and size, rather than being assisted by external penetration means to penetrate the dermis.

[0003] This method of drug application often uses patches to assist in covering the drug on the skin surface. The most common ones are packaged drug patches, which are taken out from the sealed packaging bag and the protective film structure is opened. Then, the patches are spread on the patient's skin surface with the drug and fixed. When packaging this type of patch, its four sides need to be sealed. Most of the current methods use a hot melt edge sealing mechanism. The upper and lower hot melt pressure plates are closed to bond the four sides of the sealed bag. However, since the four sides are bonded at the same time, a lot of air is easily retained inside after sealing, and foreign matter in the air will inevitably come into contact with the drug, reducing the drug's time-effectiveness. Therefore, it is necessary to develop a new type of packaging equipment for patch edge sealing to address the shortcomings of the existing technology. Utility Model Content

[0025] The edge sealing machine head 2 includes a heat sealing edge component 21 fixedly connected to the bottom of the movable end of the telescopic rod 5, and an exhaust bag 22 is embedded in the bottom of the heat sealing edge component 21. The bottom of the exhaust bag 22 is flush with the bottom of the heat sealing edge component 21. After the exhaust bag 22 is expanded, its bottom extends to the bottom of the heat sealing edge component 21. A linkage component 23 is provided on the outside of the heat sealing edge component 21. The bottom of the exhaust bag 22 contacts the top of the medical patch packaging bag in the positioning groove 3; due to the setting of the exhaust bag 22, during the period of its deformation recovery, the tendency of its bottom to conflict with the packaging bag is radially spread from the middle of the packaging bag to the surrounding areas, thereby It can effectively squeeze out the air inside the packaging bag, thereby improving the effect of the four-sealing plate packaging of the medical patch; due to the setting of the linkage component 23, it can adapt to the deformation of the exhaust bag 22 with the cooperation of the heat-sealing edge component 21, ensuring that the exhaust bag 22 can be inflated again after the edge-sealing machine head 2 rises, so as to prepare for the next action; more importantly, it can assist the recovery of the airbag body 221, and avoid the airbag body 221 recovering to overcome the friction resistance between the piston plate 234 and the sealing cavity 212, thereby avoiding the situation where the airbag body 221 recovers slowly and is squeezed to the bottom of the edge-sealing hot melt head 213 on all sides.

[0026] Among them, the edge banding heads 2 , the positioning slots 3 and the telescopic rods 5 are in one-to-one correspondence, the edge banding head 2 is directly above the positioning slots 3 , and the telescopic rods 5 are directly above the edge banding head 2 .

[0027] Among them, the end of the positioning groove 3 away from the connecting frame 4 is in an open state, the bottom of the positioning groove 3 is in a smooth state, and the inner cavity size of the positioning groove 3 is larger than the outer diameter size of the edge sealing head 2; due to the setting of the positioning groove 3, the position of the medical patch to be packaged can be well limited, ensuring that the edge sealing head 2 can be qualifiedly packaged after it is lowered, and at the same time, the open positioning groove 3 also facilitates the removal of the medical patch with the edge sealed inside it.

[0028] Among them, the heat sealing edge component 21 includes an integrated box 211 fixedly connected to the bottom of the telescopic rod 5, and a sealed cavity 212 is opened at the bottom of the integrated box 211. The bottom of the integrated box 211 is embedded with a coaxial edge sealing hot melt head 213 and an insulation ring 214. The insulation ring 214 is sleeved on the inner side of the edge sealing hot melt head 213, and the bottoms of the edge sealing hot melt head 213 and the insulation ring 214 both extend to the bottom of the integrated box 211; due to the setting of the insulation ring 214, the heat of the edge sealing hot melt head 213 can be effectively isolated, thereby reducing the impact of heat on the exhaust bag 22.

[0029] Among them, the exhaust bag 22 includes an airbag body 221 fixedly sleeved on the bottom of the inner cavity of the sealing cavity 212. The upper end of the airbag body 221 is a rigid structure, and the lower end of the airbag body 221 is an elastic structure. An air hole 222 is opened in the middle of the upper end of the airbag body 221. The upper end of the air hole 222 is connected to the sealing cavity 212, and the lower end of the air hole 222 is connected to the interior of the airbag body 221; since the upper end of the airbag body 221 is a rigid structure, it is ensured that after it is expanded, its expansion and contraction are completely borne by its lower end, thereby ensuring that it can be pressed onto the medical patch to be packaged after expansion.

[0030] Among them, the linkage assembly 23 includes a linkage frame 231 covered on the outside of the integrated box 211, the top of the linkage frame 231 is located above the integrated box 211 and is provided with a limiting hole 232, the linkage frame 231 is sleeved on the outside of the telescopic rod 5 through the limiting hole 232, and the linkage frame 231 is fixedly connected to the vertical rods located on the left and right sides of the integrated box 211, and the lower ends of the vertical rods extend to the bottom of the integrated box 211; due to the setting of the linkage frame 231, its lower end can move upward relative to the heat-sealed edge assembly 21 after pressing against the medical patch, so as to assist the recovery of the airbag body 221 to drive the piston plate 234 to move upward, thereby avoiding the situation where the airbag body 221 recovers and discharges the internal air to overcome the friction resistance between the piston plate 234 and the sealing cavity 212.

[0031] The sealing chamber 212 is sealed with a piston plate 234, and the top of the piston plate 234 is fixedly connected to a plurality of linkage slide rods 233. The upper ends of the linkage slide rods 233 pass through the linkage frame 231 and are fixedly connected to the bottom of the linkage frame 231. The linkage slide rods 233 are movably sleeved inside the integrated box 211.

[0032] A return spring 235 is also provided inside the sealing cavity 212, and the upper end of the return spring 235 abuts against the top of the inner cavity of the sealing cavity 212, and the lower end of the return spring 235 abuts against the top of the piston plate 234; due to the setting of the return spring 235, the airbag body 221 is ensured to expand under the action of its elastic force so as to press the medical patch to be packaged, thereby expelling the residual air inside.

[0033] The working principle and use process of this utility model:

[0034] Place the medical patch packaging bag to be sealed at the lower left side of the edge sealing machine head 2 inside the positioning groove 3. With the cooperation of the machine base 1, the connecting frame 4 controls the operation of the telescopic rod 5, so that the edge sealing machine head 2 can be slowly moved downward. As the edge sealing machine head 2 continues to move downward, the bottom of the airbag body 221 and the bottom of the linkage frame 231 are successively abutted against the top of the packaging bag.

[0035] Then, as the edge sealing machine head 2 continues to move downward, the airbag body 221 presses the packaging bag, and the air inside the airbag body 221 can be discharged through the air vent 222. At the same time, due to the upward movement of the linkage frame 231 relative to the integrated box 211, it drives the piston plate 234 to move upward along the inside of the sealing cavity 212 relative to the integrated box 211 through the linkage slide rod 233 and compresses the return spring 235. At the same time, the air inside the airbag body 221 can smoothly enter the inside of the sealing cavity 212 through the air vent 222, so that the airbag body 221 can return to its original shape. During the restoration period, its bottom portion spreads from the middle to the surrounding areas and is pressed against the top of the packaging bag in sequence, thereby squeezing out the air inside the packaging bag in an orderly manner.

[0036] When the integrated box 211 moves down until the bottom of the edge sealing hot melt head 213 embedded in the bottom thereof abuts against the packaging bag, after a period of time, the contact portion of the packaging bag with the edge sealing hot melt head 213 is hot-melted and bonded together, thereby completing the four-edge sealing packaging.
