Description

Technical Field

[0001] The present invention relates to the technical field of drug packaging testing, in particular to a testing device for a single-dose high-barrier drug easy-to-tear packaging film. Background Art

[0002] The main function of pharmaceutical packaging is to protect the drugs. During the production, transportation, storage and use of drugs, packaging can effectively prevent the drugs from being contaminated, deteriorating or damaged. For example, moisture-proof, light-proof, anti-oxidation and other packaging methods can extend the shelf life of drugs.

[0003] In the prior art, when testing packaging films, the two ends of the packaging films are often grabbed and moved in opposite directions until the packaging films break. Often, only the lateral tensile force can be tested, and the test results are single. It is impossible to simulate the force strength under actual conditions, and the accuracy is insufficient. At the same time, when it is necessary to test the tearing force of the packaging film, the same tearing force is often used, and the qualification of the packaging film is judged according to the tearing result. It is impossible to test the accurate force values of different types of packaging films, thereby judging the applicable population, and the practicality is low.

At the same time, the first limiting rod 57 deflects along the first reference axis 55 under the action of the coil spring, driving the support rod 70 to slide along the sliding frame 69, so that the support frame 72 slides synchronously, and the rotating matching bevel gear 81 disengages from the linkage bevel gear 8 7. The rotating shaft 86 drives the test assembly 9 to reset under the action of the third coil spring 85. The first limiting lever 57 is reset under the action of the first coil spring 56 and is limited to the reset position by the provided first auxiliary shaft 58. After the second track 64 rotates one circle along the rolling wheel 71, the other side of the protrusion 63 cooperates with the side end of the rolling wheel 71, causing it to abut against the side end of the second limiting lever 67. Under the action of the second coil spring 66, it deflects along the second reference axis 65, thereby driving the rolling wheel 71 to enter the first track 60, so that the driving support rod 70 is reset on the sliding frame 69, and the side end of the matching bevel gear 81 is re-engaged with the side end of the linkage bevel gear 87. After the rolling wheel 71 passes the second limiting lever 67, the second limiting lever 67 is reset under the action of the second coil spring 66 and is limited to the reset position by the provided second auxiliary shaft 68, thereby facilitating the switching of kinetic energy, enabling continuous testing of different packaging films, and performing multiple testing methods on a single packaging film, so that the packaging film can be tested in multiple ways, thereby improving the convenience of use of the device.

[0042] When the rolling wheel 71 is in the first track 60, the cooperating bevel gear 81 drives the linked bevel gear 87 to rotate synchronously, thereby driving the first oblique plates 95 on both sides to rotate synchronously under the action of the rotating shaft 86, and then driving the connecting shaft 96 and the second oblique plate 97 to rotate synchronously at the side ends of the fixed seat 94, so that under the cooperation of the rotating sleeve 98 and the tripod 99, the arc member 101 is driven to move along the semi-arc track 91, so that the two test clamps 102 grab the side edges of the packaging film and move in an arc in relative directions, thereby testing the degree of stress of the vertical tension of the packaging film and gradually increasing its stress angle. When the rolling wheel 71 enters the second track 64, the cooperating bevel gear 81 disengages the linked bevel gear 87 and engages with the auxiliary bevel gear 1111, thereby driving the kinetic energy shaft 1112 to rotate synchronously, and under the action of the first transmission belt 1116, the The first control shaft 1114 and the control bevel gear 1115 are driven to rotate synchronously, thereby driving the trigger bevel gear 1117 and the second control shaft 1118 to rotate synchronously, and the second transmission belt 1123 is provided to drive the transmission shaft 1122 and the triangle piece 1124 to rotate synchronously. In the process of rotation, the sliding plate 1125 is driven to move along the control sliding frame 1119 toward the test bench 4 under the action of the pull rod 1131 and the displacement track 1130, and the connecting support rod 1127 is made to move linearly and arcuately at the same time under the cooperation of the triangle piece 1124 and the L-shaped frame 1128, so as to facilitate the tearing force test of the packaging film, thereby avoiding the possibility of a single force test result of the packaging film, improving the accuracy of the test result, and at the same time ensuring the strength of the packaging film and avoiding the possibility of damage under specific circumstances;

[0043] When the triangle piece 1124 rotates and drives the connecting support rod 1127 to move, the toggle frame 122 is driven to move synchronously through the connecting rod 121, so that the toggle frame 122 moves in an arc shape to the bottom of the packaging film and moves upward along the arc from the bottom to tear it, so that the force-bearing L-shaped plate 123 compresses the telescopic spring 124 when it contacts the packaging film, thereby driving the recording plate 125 to move downward along the inner wall of the toggle frame 122, and in the process of moving, a plurality of arc-shaped openings 126 are stepped down at the side ends of the card columns 127. When the packaging film is torn, the force-bearing L-shaped plate 123 stops falling after losing the resistance. At this time, the staff can judge the accurate value of the force on the packaging film according to the position of the card column 127 at this time, and under the continuous rotation of the triangle piece 1124, the L-shaped trigger block 132 is abutted against the side end of the reset block 133, thereby During the resetting process of the movable frame 122, the positioning frame 130 and the reset frame 128 are driven to slide synchronously along the through groove 129, and the spring telescopic rod 131 is stretched, so that the clamping column 127 is disengaged from the arc opening 126. At this time, the force-bearing L-shaped plate 123 is reset under the action of the telescopic spring 124, and when the clamping jaws 102 are tested next time, the clamping column 127 is reset under the action of the spring telescopic rod 131, which facilitates the next tearing test, thereby avoiding the inability to test the accurate values of the forces on different types of packaging films, and being able to judge the applicable population through the recorded values, thereby improving the practicality of the device, and after the staff completes the recording, when the power component 112 is reset by the driving component 5, the recording component 12 is driven to complete the reset with the cooperation of the testing component 9, thereby facilitating the next work, thereby improving the convenience of the device.
