Description

Technical Field

[0001] The invention relates to the technical field of composite film heat-sealing performance detection, in particular to a heat-sealing performance detection device for a medicinal composite film. Background Art

[0002] With the development of the pharmaceutical industry, the safety and effectiveness of pharmaceutical packaging materials have become one of the key research areas. As an innovative packaging material, pharmaceutical composite films have been widely used in pharmaceutical packaging due to their excellent barrier properties, mechanical strength and chemical stability. These properties not only help protect drugs from the influence of the external environment (such as air and humidity), but also maintain the stability of the physical and chemical properties of drugs, thereby ensuring the safety and effectiveness of drugs during transportation, storage and use; and heat sealing performance is one of the key indicators for evaluating the quality of pharmaceutical composite films. It not only determines the sealing effect of the packaging, but also directly affects the shelf life of the drug and the safety of consumers. For pharmaceutical composite films, excellent heat sealing performance can effectively prevent external factors such as air and moisture from causing adverse effects on drugs. At the same time, reasonable heat sealing strength can prevent packaging rupture due to external forces and reduce the possibility of drug contamination.

[0003] At present, the detection method for the heat sealing performance of pharmaceutical composite films is mainly based on the principle of gas pressure difference. The specific operations include: first, it is necessary to manually tear a small hole in a complete small bag along one side, and then insert a thin trachea into the bag through the small hole, and ensure that the trachea can smoothly reach other parts of the bag; then, the gap between the trachea and the torn opening is sealed by using tape or other means to ensure that no leakage occurs during the subsequent pressurization process; finally, the bag is continuously inflated through the trachea until the bag begins to leak due to excessive internal pressure; at this time, the heat sealing performance of the pharmaceutical composite film can be judged by observing the location and degree of the leakage.

[0004] However, this existing method has certain limitations and shortcomings. For example, when the bag is torn open manually, this behavior itself has destroyed part of the structure of the medicinal composite film, especially the heat-sealed edge near the torn opening, which may cause the test results to fail to fully reflect the actual heat-sealing performance of the medicinal composite film. In addition, due to possible human errors during manual operation, this may further affect the final detection accuracy. Summary of the invention

[0033] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the driving mechanism includes a second sleeve 801, a second porous sponge 802, a second electric push rod 803, a second air pump 804 and a first air pipe 805; the second sleeve 801 is slidably connected to the outer side of the hollow cylinder 7; the second porous sponge 802 is connected to the lower inner side of the second sleeve 801; two second electric push rods 803 are also arranged on the outer side of the hollow cylinder 7, and the telescopic rods of the two second electric push rods 803 are connected to the second sleeve 801, and the second electric push rods 803 are used to drive the second sleeve 801 to rise and fall on the outer side of the hollow cylinder 7; the second air pump 804 is connected to the left front side of the slider of the electric slide rail 5, and the air inlet of the second air pump 804 is connected to the hollow cylinder 7 through the first air pipe 805.

[0034] See also Figure 7 and Figure 8 As shown, the rotating mechanism includes a mounting frame 1301 and a servo motor 1302; the upper end of the hollow tube 11 is connected to the mounting frame 1301, and the mounting frame 1301 is located on the inner side of the hollow cylinder 7; the servo motor 1302 is installed on the mounting frame 1301, and the output shaft of the servo motor 1302 is connected to the upper end of the rotating rod 12, and the servo motor 1302 is used to drive the rotating rod 12 to rotate.

[0035] See also Figure 1 and Fig.10 As shown, the boosting mechanism includes a boosting pump 1701, a second air pipe 1702 and an air pressure regulating valve 1703; the boosting pump 1701 is connected to the front right part of the slider of the electric slide rail 5; the air outlet of the boosting pump 1701 is connected to the hollow cylinder 7 through the second air pipe 1702; the second air pipe 1702 is provided with an air pressure regulating valve 1703, and the air pressure regulating valve 1703 is used to adjust the air flow in the second air pipe 1702.

[0036] When in use, add an appropriate amount of clean water into the water tank 1, and then place the medicinal composite film bag in the middle of the top of the rotating table 3 (the medicinal composite film bag usually has an upper and lower surface, and the four sides are fixed together by heat sealing), so that the bottom surface of the medicinal composite film bag is in contact with the first porous sponge 402, and then the rotating table 3 is manually pulled to rotate, so that the rotating table 3 drives the medicinal composite film bag to rotate to the bottom of the second sleeve 801, and then the second electric push rod 803 is controlled to drive the second sleeve 801 and the second porous sponge 802 to move downward. When the second porous sponge 802 contacts the top surface of the medicinal composite film bag, the medicinal composite film bag will prevent the second porous sponge 802 from continuing to move downward. As the second sleeve 801 continues to move downward, the second sleeve 801 will apply pressure to the second porous sponge 802, so that the second porous sponge 802 is deformed, so that the second porous sponge 802 is tightly attached to the top surface of the medicinal composite film bag. At the same time, the second porous sponge 802 also exerts pressure on the medicinal composite film bag, so that the medicinal composite film bag squeezes the first porous sponge 402 to deform, so that the first porous sponge 402 is tightly attached to the bottom surface of the medicinal composite film bag. Then, the air in the first sleeve 401 is extracted by the first vacuum pump 403, so that the first sleeve 401 is in a negative pressure state, so that the bottom surface of the medicinal composite film bag is adsorbed on the first porous sponge 402 and the top of the first sleeve 401. At the same time, the second vacuum pump 804 is used to extract the air in the second sleeve 801 through the first air pipe 805, so that the second sleeve 801 is in a negative pressure state, so that the top surface of the medicinal composite film bag is adsorbed on the second porous sponge 802 and the bottom of the second sleeve 801.

[0037] Then, the second electric push rod 803 is controlled to drive the second sleeve 801 and the second porous sponge 802 to move upward and reset, so that the second sleeve 801 and the second porous sponge 802 absorb the top surface of the medicinal composite film bag and rise, thereby separating the top surface and the bottom surface of the medicinal composite film bag, and then making the top surface and the bottom surface of the medicinal composite film bag farther and farther apart, so that after the subsequent blade 16 cuts the top surface of the medicinal composite film bag, the blade 16 can be separated from the bottom surface of the medicinal composite film bag by a certain distance, thereby preventing the bottom surface of the medicinal composite film bag from being cut by the blade 16. When the top surface of the medicinal composite film bag rises to contact with the blade 16, the blade 16 will cut an incision on the top surface of the medicinal composite film bag. Then, as the top surface of the medicinal composite film bag continues to rise, the blade 16, the fastening plate 15 and the right-angle commutator 14 will enter the inner side of the medicinal composite film bag from the incision until the top surface of the medicinal composite film bag contacts the bottom surface of the hollow tube 7. When the blade 16, the fastening plate 15 and the right-angle commutator 14 completely enter the inner side of the medicinal composite film bag, the hollow shaft motor 10 and the hollow tube 7 are driven by the first electric push rod 9. 11, the rotating rod 12, the right-angle commutator 14, the fastening plate 15 and the blade 16 move upward (here, the rising speed of the fastening plate 15 and the blade 16 cannot exceed the rising speed of the top surface of the medicinal composite film bag, otherwise the fastening plate 15 and the blade 16 will leave the incision on the top surface of the medicinal composite film bag), and then the servo motor 1302 drives the rotating rod 12 to rotate, so that the rotating rod 12 drives the fastening plate 15 and the blade 16 to rotate through the transmission of the right-angle commutator 14 until the fastening plate 15 and the blade 16 are in a horizontal state, and then the hollow shaft motor 10 drives The movable hollow tube 11, the right-angle commutator 14, the fastening plate 15 and the blade 16 are rotated ninety degrees in the horizontal direction so that the fastening plate 15 is flush with the incision on the top surface of the medicinal composite film bag. Then, when the fastening plate 15 moves upward to contact the inner top surface of the medicinal composite film bag, the fastening plate 15 will press the top surface of the medicinal composite film bag against the bottom surface of the hollow tube 7, and at the same time, the incision on the top surface of the medicinal composite film bag is between the fastening plate 15 and the hollow tube 7. In this way, the incision on the top surface of the medicinal composite film bag can be closed, thereby sealing the inner side of the medicinal composite film bag.

[0038] Subsequently, air is pumped into the first sleeve 401 through the first vacuum pump 403 to restore the air pressure in the first sleeve 401 to normal, thereby causing the first porous sponge 402 and the first sleeve 401 to loosen the bottom surface of the medicinal composite film bag, and the first porous sponge 402 returns to its original state. At the same time, the second vacuum pump 804 is used to pump air into the second sleeve 801 through the first air pipe 805 to restore the air pressure in the second sleeve 801 to normal, thereby causing the second porous sponge 802 and the second sleeve 801 to loosen the top surface of the medicinal composite film bag, and the second porous sponge 802 returns to its original state. Thereafter, the rotating table 3 is manually pushed to reverse and reset, and then the electric slide rail 5 drives the bracket 6, the hollow cylinder 7, the first electric push rod 9, the hollow shaft motor 10, the hollow tube 11, the right-angle commutator 14 and the fastening plate 15 to move downward, thereby driving the medicinal composite film bag to move downward until the medicinal composite film bag enters The clean water in the water tank 1 is used to completely submerge the entire medicinal composite film bag. Then, an appropriate amount of air is pumped into the second air pipe 1702 and the hollow cylinder 7 through the booster pump 1701 and the air pressure regulating valve 1703, so that the air in the hollow cylinder 7 enters the incision on the top surface of the medicinal composite film bag, thereby allowing the air to enter the inner side of the medicinal composite film bag, and then the inner side of the medicinal composite film bag is pressurized. Subsequently, an appropriate amount of air is continuously pumped into the second air pipe 1702 and the hollow cylinder 7 through the booster pump 1701 and the air pressure regulating valve 1703, so as to continuously increase the air pressure in the medicinal composite film bag until the inner side of the medicinal composite film bag begins to leak due to excessive air pressure. Subsequently, the operator can observe the medicinal composite film bag in the water and judge the heat sealing performance of the medicinal composite film by finding the position and degree of air leakage in the medicinal composite film bag. In this way, the heat sealing performance of the medicinal composite film bag can be tested.

[0039] After the heat sealing performance of the medicinal composite film bag is tested, the electric slide rail 5 drives the bracket 6, the hollow cylinder 7, the first electric push rod 9, the hollow shaft motor 10, the hollow tube 11, the right angle commutator 14 and the fastening plate 15 to move upward and reset, thereby driving the tested medicinal composite film bag to move upward, so that the tested medicinal composite film bag leaves the clean water in the water tank 1, and then the first electric push rod 9 drives the hollow shaft motor 10, the hollow tube 11, the rotating rod 12, the right angle commutator 14, the fastening plate 15 and the blade 16 to move downward and reset, so that the fastening plate 15 is released and pressed on The top surface of the composite film bag on the bottom surface of the hollow cylinder 7 is then driven by the hollow shaft motor 10 to rotate the hollow tube 11, the right-angle commutator 14, the fastening plate 15 and the blade 16 in the horizontal direction in the opposite direction by ninety degrees to reset, and then the servo motor 1302 drives the rotating rod 12 to reverse and reset, so that the rotating rod 12 drives the fastening plate 15 and the blade 16 to reverse and reset through the transmission of the right-angle commutator 14, and finally the inspected medicinal composite film bag is manually removed from the fastening plate 15, so that the blade 16, the fastening plate 15 and the right-angle commutator 14 can be removed from the inner side of the medicinal composite film bag.

[0040] See also Fig.11 As shown, an arc-shaped limit block 18 is also included; the arc-shaped limit block 18 is connected to the connecting frame 2, and the arc-shaped limit block 18 is used to limit the rotating table 3.

[0041] By setting the arc-shaped limit block 18, the arc-shaped limit block 18 can be used to limit the rotation angle of the turntable 3, so that when the operator rotates or reverses the turntable 3 to adjust the position, he only needs to rotate or reverse the turntable 3 until it contacts the arc-shaped limit block 18, so that the turntable 3 can stay in the accurate position, thereby facilitating the operator to rotate or reverse the turntable 3 to adjust the position.

[0042] See also Figure 1 and Fig.12 As shown, it also includes a convergence mechanism, which includes a plastic cover 19, a transparent tube 20, a third electric push rod 21 and a sealing plate 22; the plastic cover 19 is connected between the two brackets 6, the hollow cylinder 7 is located on the inner side of the plastic cover 19, the plastic cover 19 is made of transparent material, and the first air pipe 805 and the second air pipe 1702 both penetrate the plastic cover 19; the top of the plastic cover 19 is connected to the transparent tube 20, and the transparent tube 20 is used to converge the bubbles in the plastic cover 19; the side of the transparent tube 20 is connected to the third electric push rod 21; the sealing plate 22 is connected to the telescopic rod of the third electric push rod 21, and the sealing plate 22 is used to shield and seal the top of the transparent tube 20.

[0043] When the electric slide rail 5 drives the bracket 6, the hollow cylinder 7, the first electric push rod 9, the hollow shaft motor 10, the hollow tube 11, the right-angle commutator 14 and the fastening plate 15 to move downward, the bracket 6 will drive the plastic cover 19, the transparent tube 20, the third electric push rod 21 and the sealing plate 22 to move downward synchronously. When the plastic cover 19 contacts the clean water, as the plastic cover 19 continues to move downward, the air in the plastic cover 19 will be discharged from the transparent tube 20. When the medicinal composite film bag is submerged in the clean water, the plastic cover 19, the transparent tube 20, the third electric push rod 21 and the sealing plate 22 can be made to continue to descend and then be submerged in the clean water together. Then, the third electric push rod 21 is controlled to drive the sealing plate 22 to move downward, so that the sealing plate 22 covers the top of the transparent tube 20, thereby sealing the inside of the transparent tube 20; thereafter, when the medicinal composite film bag leaks during the detection in water, the leaked gas will form bubbles in the clean water and float upward. When the bubbles float upward When the plastic cover 19 is moved to contact the plastic cover 19, the bubbles will continue to float upward along the inner wall of the plastic cover 19 to the transparent tube 20, so that all the bubbles are gathered in the transparent tube 20 to form large bubbles. In this way, the operator only needs to observe whether there are bubbles formed in the transparent tube 20 to know whether there is leakage in the medicinal composite film bag, which is convenient for the operator to make a judgment; after that, when the medicinal composite film bag completes the heat sealing performance test, the third electric push rod 21 is controlled to drive the sealing plate 22 to move upward and reset, so that the sealing plate 22 no longer covers the top of the transparent tube 20, and then when the electric slide rail 5 drives the bracket 6, the hollow cylinder 7, the first electric push rod 9, the hollow shaft motor 10, the hollow tube 11, the right-angle commutator 14 and the fastening plate 15 to move upward, the bracket 6 will drive the plastic cover 19, the transparent tube 20, the third electric push rod 21 and the sealing plate 22 to move upward and reset synchronously, so that the plastic cover 19, the transparent tube 20, the third electric push rod 21 and the sealing plate 22 leave the clean water.

[0044] See also Fig.12 As shown, a vibrator 23 is also included; the vibrator 23 is arranged on the outside of the plastic cover 19, and the vibrator 23 is used to drive the plastic cover 19 to vibrate.

[0045] By setting the vibrator 23, after the plastic cover 19 is submerged in water, the vibrator 23 can be started to drive the plastic cover 19 to vibrate slightly. When the bubbles float upward and contact the plastic cover 19, the vibration of the plastic cover 19 can prevent the bubbles from remaining on the inner wall, thereby preventing the bubbles from remaining on the inner wall of the plastic cover 19 and affecting the operator's judgment after viewing the transparent tube 20. Afterwards, when the medicinal composite film bag completes the heat sealing performance test, the vibrator 23 is turned off.

[0046] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
