Description

Technical Field

[0001] The invention relates to the technical field of plastic bottle detection, and in particular to a plastic bottle multi-region compressive strength detection device. Background Art

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, they are heated at high temperature and blow-molded, extruded, or injection-molded through plastic molds. They are mainly used for liquid or solid disposable plastic packaging containers such as beverages, foods, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles will inevitably encounter collisions, extrusions, and thermal expansion and contraction of objects in the plastic bottles during the application process. Therefore, it is necessary to test the strength of plastic bottles during production to ensure that the plastic bottles will not deform when they encounter collisions, extrusions, and thermal expansion and contraction of objects in the plastic bottles.

[0003] The existing pressure testing machine needs to apply different pressures to multiple groups of sample bottles in multiple times during the testing process. However, before the compressive strength test of the plastic bottle, it needs to be clamped and fixed by a clamping structure. However, the plastic bottle will expand during the compressive strength test. If the clamping structure is still clamped in the specified position, the plastic bottle will generate a reaction force during the compressive test, which will form a reverse restraint force on the bottle body, which is equivalent to superimposing an additional force on the load applied by the pressure testing machine, thereby affecting the accuracy of the test. For this reason, we provide a multi-region compressive strength testing device for plastic bottles to solve the above problems. Summary of the invention

This dynamic compensation mechanism avoids the mechanical constraint of the traditional rigid clamping on the expansion deformation, and eliminates the reverse constraint force caused by the fixed clamping position. When the plastic bottle expands too much, the pressure wheel will not be reset and pressed on the outer wall of the plastic bottle in time after expansion through the limitation of the ratchet and ratchet teeth, so that the plastic bottle can be limited within a certain range.

Since how the linear module drives the equipment to move is an existing technology, this scheme does not draw a specific driving structure. When the output end of the hydraulic cylinder drives the connecting seat to drive the detection pressure head to move downward to perform a pressure test on an empty plastic bottle, the first linear module can drive the sliding seat to move horizontally, and another plastic bottle filled with liquid can be pressed for detection. At the same time, the plastic bottle that has been tested is replaced by the staff when the device is performing a compressive strength test on another one. This will not affect the detection efficiency, so that the device can be tested continuously, thereby improving the efficiency of the compressive strength test of the plastic bottles.

A guide rod 10 is fixedly connected to the top of the sliding seat 3, and a through groove matching the guide rod 10 is opened on the inner side of the fixed sleeve 9. The connecting seat 7 is slidably connected to the guide rod 10 through the fixed sleeve 9. The clamping assembly includes an auxiliary seat 13 arranged above the detection platform 1, and a stand 14 is fixedly connected to the top of the auxiliary seat 13. Two rotating shafts 17 are rotatably connected to the inner side of the stand 14. A second driving motor 16 is installed on the top of the stand 14, and the second linear module 16 is fixedly connected to the bottom of the connecting seat 7. The output ends of the two driving motors 16 are fixedly connected to a rotating shaft 17, and the outer walls of the two rotating shafts 17 are fixedly connected to a first spur gear 20, and the two first spur gears 20 are meshed. The adaptive regulator includes a plurality of second fixed seats 28 fixedly connected to the outer wall of the rotating shaft 17, and each second fixed seat 28 is arranged above a pressure block 18, and the top of the pressure block 18 is fixedly connected to a first rotating shaft 26, and one end of the first rotating shaft 26 passes through the top of the second fixed seat 28 and is rotatably connected to the second fixed seat 28, and the outer wall of the first rotating shaft 26 is fixedly connected to a ratchet 27, and a second torsion spring 35 is installed between the ratchet 27 and the second fixed seat 28, and the adaptive regulator also includes a second rotatably connected to the top of the second fixed seat 28. The second rotating shaft 32 has a ratchet 42 meshing with the ratchet 27 fixedly connected to its outer wall, a first torsion spring 33 is installed between the ratchet 42 and the second fixed seat 28, a reset drive unit is provided between the second rotating shaft 32 and the top of the auxiliary seat 13, a limit assembly for limiting the pressing block 18 is provided at the top of the auxiliary seat 13, the reset drive unit includes an L-shaped support 41 fixedly connected to the top of the auxiliary seat 13, a U-shaped frame 24 is fixedly connected to the top of the L-shaped support 41, a plurality of arc-shaped racks 25 are fixedly connected to the outer wall of the U-shaped frame 24, and each arc-shaped rack 25 is correspondingly arranged on one side of a second fixed seat 28, and a second spur gear 34 meshing with the arc-shaped rack 25 is fixedly connected to the outer wall of the second rotating shaft 32; The clamping assembly is provided with two groups, one group clamps empty bottles, and the other group clamps bottles filled with liquid. Since how the linear module drives the device to move is an existing technology, the specific driving structure is not drawn in this scheme. When the output end of the hydraulic cylinder 6 drives the connecting seat 7 to drive the detection pressure head 8 to move downward to perform a pressure test on an empty plastic bottle 21, the first linear module 2 can drive the sliding seat 3 to move horizontally, and another plastic bottle 21 filled with liquid can be pressed and tested. At the same time, when the device performs a compressive strength test on another plastic bottle 21 that has been tested, the staff replaces it, which will not affect the detection efficiency, so that the device can be tested continuously, thereby improving the efficiency of the compressive strength test of the plastic bottle 21; When the plastic bottle 21 is placed on the top of the auxiliary table 11, the two second drive motors 16 can be started. The output ends of the two second drive motors 16 respectively drive a rotating shaft 17 to drive a group of pressing wheels 19 to rotate toward the plastic bottle 21. When one rotating shaft 17 rotates, the other first spur gear 20 drives another rotating shaft 17 to rotate, so that the two groups of pressing wheels 19 rotate toward the plastic bottle 21. When the second drive motor 16 stops running, the two groups of pressing wheels 19 are clamped on the outer wall of the plastic bottle 21, so as to limit the position of the plastic bottle 21. When the plastic bottle 21 is in the process of compressive strength testing, when the connecting seat 7 applies pressure to the top of the plastic bottle 21, the plastic bottle 21 is easy to expand. When the plastic bottle 21 expands, its expanded part pushes the pressing wheel 19 to drive the pressing block 18 to rotate, so that the first rotating shaft 26 drives the second torsion spring 35 to rotate through the ratchet 27, so that the second torsion spring 35 is twisted. When the ratchet 27 rotates, the ratchet 42 can be driven to drive the second rotating shaft 32 to rotate. When a tooth on the outer side of the ratchet 27 is separated from the ratchet 42, and another tooth on the outer side of the ratchet 27 is rotated to the position of the ratchet 42, the ratchet 42 can be reset and clamped to the outer side of the ratchet 27 under the action of the first torsion spring 33, so as to limit the ratchet 27 in one direction. If the plastic bottle 21 expands only slightly and the ratchet teeth 42 do not disengage from the teeth of the ratchet wheel 27, the pressing wheel 19 can always be attached to the outer wall of the plastic bottle 21 under the action of the second torsion spring 35; The pressure wheel 19 moves outward synchronously with the expansion of the plastic bottle 21, and the elastic deformation of the second torsion spring 35 provides continuous contact force. This dynamic compensation mechanism avoids the mechanical constraint of the expansion deformation by the traditional rigid clamping, and eliminates the reverse constraint force caused by the fixed clamping position. When the plastic bottle 21 expands too much, the pressure wheel 19 will not be reset and pressed on the outer wall of the plastic bottle 21 in time after expansion through the limitation of the ratchet 27 and the ratchet 42, so that the plastic bottle 21 can be limited within a certain range. The traditional clamping structure will generate a reverse constraint force due to the fixed limitation when the bottle body expands, which will be superimposed on the detection pressure and affect the accuracy. This design allows the pressure wheel 19 to dynamically adjust its position with the expansion through the irreversible rotation of the ratchet 27 and the ratchet 42, eliminating the additional stress generated by the fixed clamping, ensuring the purity of the detection load, and thus improving the accuracy of the detection; When the output end of the second drive motor 16 drives the pressure wheel 19 to expand and reset, and the rotating shaft 17 rotates to drive the second spur gear 34 to reset, the second spur gear 34 contacts the arc-shaped rack 25, and the ratchet 42 is driven by the arc-shaped rack 25 to separate from the ratchet wheel 27, so that the second torsion spring 35 is no longer subject to external force to drive the pressure wheel 19 to automatically reset, so that the device can be used continuously.

[0032] Reference Figure 1 to Figure 8 A flip assembly for driving the clamping assembly to flip is provided on the top of the test platform 1, and the flip assembly includes a first fixed seat 12 fixedly connected to the top of the test platform 1, a first drive motor 15 is installed on one side of the first fixed seat 12, and the output end of the first drive motor 15 is connected to a connecting shaft 29, and one end of the connecting shaft 29 passes through the outside of the first fixed seat 12 and is fixedly connected to the auxiliary seat 13, and the connecting shaft 29 is rotatably connected to the first fixed seat 12, and the limiting assembly includes a rectangular slide bar 37 slidably connected to the inner side of the stand 14, and one end of the rectangular slide bar 37 passes through the outer fixed seat 14 of the stand 14. An auxiliary block 31 is connected, a connecting spring 36 is installed between the auxiliary block 31 and the stand 14, a power rod 22 is fixedly connected to one side of the auxiliary block 31, a connecting rod 23 is fixedly connected to one end of the power rod 22, a plurality of U-shaped frames 24 are fixedly connected to one end of the connecting rod 23, and each U-shaped frame 24 is arranged on one side of a pressing block 18, and an auxiliary wheel 40 is rotatably connected to the inner side of the U-shaped frame 24, and the limiting assembly also includes a spherical rod 38 fixedly connected to one end of the auxiliary block 31, and a ring block 30 is fixedly connected to one side of the first fixed seat 12, and an arc-shaped inclined surface 39 is arranged on the outer wall of the ring block 30; A limiting component is provided on one side of an auxiliary seat 13, so only the downwardly adjusted pressing block 18 is limited, and the other one is used normally. When the plastic bottle 21 needs to be tested for the side compressive strength, an electric push rod for driving the auxiliary table 11 to move downward is installed inside the testing platform 1, which is not drawn in the figure. The auxiliary table 11 is first driven to retract into the inside of the testing platform 1 by the electric push rod, and then the two first driving motors 15 can be started. The output end of the first driving motor 15 drives the connecting shaft 29 to drive the auxiliary seat 13 to rotate, so as to adjust the plastic bottle 21 to a horizontal position. Under the action of the linear module, the testing pressure head 8 can perform compressive strength tests on the plastic bottle 21 in a horizontal state at different positions respectively; The auxiliary wheel 40 is initially arranged on the side away from the pressing block 18. When the auxiliary seat 13 drives the plastic bottle 21 to rotate, the spherical rod 38 contacts the arc-shaped inclined surface 39, and the auxiliary block 31 is pushed by the arc-shaped inclined surface 39 to drive the auxiliary wheel 40 to rotate toward the pressing block 18, so that the auxiliary wheel 40 is against the back of the pressing block 18, thereby limiting the pressing block 18 rotated to the bottom, so that when the compressive strength of the horizontal plastic bottle 21 is tested, the pressing block 18 at the bottom of the plastic bottle 21 will not rotate, so that it can be supported, so that the device can be applicable to a variety of detection methods, thereby improving the overall practicality of the device.
