Description

Technical Field

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

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

[0003] In the prior art, when testing a packaging film, the two ends of the packaging film are often grasped and moved in opposite directions until the packaging film breaks. Usually, only the lateral tensile force can be tested, and the test result is single. It cannot accurately simulate the stress intensity under actual conditions, and the accuracy is insufficient. At the same time, when it is necessary to test the tearing strength of the packaging film, the same force is often used for tearing, and the qualification of the packaging film is judged according to the tearing result. The accurate values of the forces on different types of packaging films cannot be tested, so as to judge the applicable population, and the practicability is low. Therefore, a device that can perform multi-angle tensile tests and simultaneously test the maximum force under tearing is needed to avoid insufficient accuracy and low practicability.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the device is in use, first, the two vertical sides of the packaging film are respectively placed in a manipulator, and one horizontal side of the packaging film is placed in the test ends of two test components. By controlling the operation of the manipulator, the horizontal tensile force value of the packaging film is tested to see if it is within the safe value. After the test is completed, by controlling the operation of the driving component, an arc-shaped pulling is performed along one horizontal side of the packaging film, thus avoiding the possibility of a single test result for the force on 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. After the test components complete their work, the side end of the packaging film is torn, and the maximum value of the force on the packaging film is recorded by the recording component, thus avoiding the inability to accurately measure the force values of different types of packaging films. The applicable population can be judged based on the recorded values, improving the practicality of the device. After the staff finishes recording, when the driving component drives the power component to reset, the recording component is driven to complete the reset with the cooperation of the test components, thus facilitating the next operation and then improving the convenience of the device. Therefore, it realizes the ability to perform multi-angle tensile tests and at the same time test the maximum value of the force under tearing, so as to avoid the effects of insufficient accuracy and low practicality.

[0013] In the present invention, through the provided driving component, the switching of kinetic energy is facilitated, and different packaging films can be continuously tested, and multiple test methods can be carried out on a single packaging film, enabling the packaging film to be detected in multiple ways and improving the convenience of using the device.

[0014] In the present invention, through the cooperation of the matching component and the test component, the two test jaws grasp the side edges of the packaging film and move in an arc in opposite directions, thereby testing the degree of force on the vertical tensile force of the packaging film and gradually increasing the force angle. Through the driving component, while the connecting rod moves linearly, it also moves in an arc, thus facilitating the test of the tearing force of the packaging film, avoiding the possibility of a single test result for the force on 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.

[0015] In the present invention, during the tearing process, the accurate value of the force applied to the packaging film is recorded by the provided recording component. Under the continuous rotational action of the triangular member, the L-shaped trigger block abuts against the side end of the reset block. Thus, during the reset process of the toggling frame, the clamping frame and the reset frame are driven to slide synchronously along the through groove, and the spring telescopic rod is stretched, causing the clamping column to disengage from the arc-shaped opening. At this time, the stressed L-shaped plate resets under the action of the telescopic spring. When the test jaw works next time, the clamping column resets under the action of the spring telescopic rod, thereby facilitating the next tearing test work. This avoids being unable to measure the accurate value of the force applied to different types of packaging films, enables the judgment of the applicable population based on the recorded values, improves the practicality of the device, and after the staff finishes recording, when the driving component drives the power component to reset, the recording component is driven to complete the reset under the cooperation of the test component, thereby facilitating the next work and improving the convenience of the device.

[0023] The use method and advantages of the present invention: The single-dose high-barrier drug easy-to-tear packaging film testing device has the following working process: like Figures 1 to 13As shown, by controlling the operation of the first drive motor 53 and the second drive motor 83, the mating shaft 82 and the mating bevel gear 81 are driven to rotate. During the rotation of the mating bevel gear 81, the Y-shaped seat 51 is driven to rotate synchronously through the drive shaft 52, thereby driving the conical disc 54, the arc-shaped frame 59, and the circular frame 62 to rotate synchronously, so that the first track 60 moves outside the rolling wheel 71. Thus, the rotating mating bevel gear 81 drives the linkage bevel gear 87 to rotate synchronously, causing the rotating shaft 86 to rotate, which is convenient for tensile testing of the packaging film. When the opening 61 of the arc-shaped frame 59 moves to the rolling wheel 71, at this time, the first limiting rod 57 moves to the outside of the rolling wheel 71. Under the action of the contact force at the side end of the end of the first limiting rod 57, the rolling wheel 71 slides along the first track 60 and enters the second track 64. At the same time, the first limiting rod 57 deflects along the first reference axis 55 under the action of the coil spring, and the driving support rod 70 slides on the sliding frame 69, causing the support frame 72 to slide synchronously. The rotating mating bevel gear 81 disengages from the linkage bevel gear 87, and the rotating shaft 86 drives the test assembly 9 to reset under the action of the third coil spring 85. The first limiting rod 57 resets under the action of the first coil spring 56, and the position of its reset is restricted by the provided first auxiliary shaft 58. After the second track 64 rotates one week along the rolling wheel 71, at this time, the other side of the convex portion 63 cooperates with the side end of the rolling wheel 71, making it contact the side end of the second limiting rod 67, and deflect along the second reference axis 65 under the action of the second coil spring 66, thereby driving the rolling wheel 71 into the first track 60, resetting the driving support rod 70 on the sliding frame 69, and making the side end of the mating bevel gear 81 mesh with the side end of the linkage bevel gear 87 again. After the rolling wheel 71 passes the second limiting rod 67, the second limiting rod 67 resets under the action of the second coil spring 66, and the position of its reset is restricted by the provided second auxiliary shaft 68, which is convenient for the switching of kinetic energy, can continuously test different packaging films, and perform multiple test methods on a single packaging film, enabling the packaging film to be detected in multiple ways and improving the convenience of using this device; When the rolling wheel 71 is within the first track 60, the bevel gear 81 cooperates to drive the linkage bevel gear 87 to rotate synchronously. Thus, under the action of the rotating shaft 86, the first inclined plates 95 on both sides are driven to rotate synchronously, and then the connecting shaft 96 and the second inclined plate 97 are driven to rotate synchronously at the side end of the fixed seat 94. Thus, under the cooperation of the rotating sleeve 98 and the tripod 99, the arc-shaped member 101 is driven to move along the semi-circular arc track 91, so that the two test jaws 102 grasp the side edge of the packaging film and perform arc-shaped movement in the opposite direction, thereby testing the stress degree of the vertical tensile force of the packaging film and gradually increasing its stress angle. When the rolling wheel 71 enters the second track 64, the bevel gear 81 cooperates to disengage from the linkage bevel gear 87 and meshes with the auxiliary bevel gear 1111, thereby driving the kinetic energy shaft 1112 to rotate synchronously. Under the action of the first transmission belt 1116, 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. Through the arranged second transmission belt 1123, the transmission shaft 1122 and the triangular member 1124 are driven to rotate synchronously, and during the rotation process, under the action of the pull rod 1131 and the displacement track 1130, the sliding plate 1125 is driven to move along the control sliding frame 1119 towards the direction of the test bench 4. And under the cooperation of the triangular member 1124 and the L-shaped frame 1128, the connecting strut 1127 performs linear movement while performing arc-shaped movement, thereby facilitating the tearing force test of the packaging film, thus avoiding the possibility of a single test result for the stress of the packaging film, improving the accuracy of its test results, and at the same time ensuring the strength of the packaging film and avoiding the possibility of damage under specific circumstances; When the triangular piece 1124 rotates to drive 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 shape 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 end of the clamping column 127. When the packaging film is torn, the force-bearing L-shaped plate 123 stops descending after losing the resistance force. At this time, the staff can judge the accurate value of the force on the packaging film according to the position of the clamping column 127 at this time, and under the continuous rotation of the triangular 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 moving frame 122, the positioning frame 130 and the resetting 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 separated from the arc-shaped 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 is convenient for 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.
