Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of plastic bottle detection, and particularly to a device for detecting the compressive strength of multiple regions of a plastic bottle. 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 are widely made of polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials. After adding the corresponding organic solvents and being heated at high temperature, they are plastic containers formed by blow molding, extrusion blow molding, or injection molding through a plastic mold. They are mainly used for disposable plastic packaging containers for liquids or solids such as beverages, foods, pickles, honey, dried fruits, edible oils, agricultural and veterinary drugs, etc. Inevitably, plastic bottles will encounter collisions, squeezes, and the thermal expansion and contraction of the objects inside the plastic bottles during application. Therefore, it is necessary to detect the strength of plastic bottles during production to ensure that plastic bottles will not deform under the conditions of collision, squeeze, and thermal expansion and contraction of the objects inside the plastic bottles.
[0003] Existing pressure testing machines need to apply different magnitudes of pressure to multiple groups of sample bottles in multiple times during the detection process. However, before detecting the compressive strength of a plastic bottle, it needs to be clamped and fixed through a clamping structure. However, the plastic bottle will expand during the compressive strength detection process. If the clamping structure still clamps at the designated position, it will cause a reaction force on the plastic bottle during the compressive detection, which will form a reverse binding force on the bottle body, equivalent to adding an additional force on top of the load applied by the pressure testing machine, thus affecting the detection accuracy. For this reason, we provide a device for detecting the compressive strength of multiple regions of a plastic bottle to solve the above problems. Summary of the Invention

[0017] Advantages of the present invention:
[0018] By setting the cooperation of parts such as the pressure wheel, as the pressure wheel moves outward synchronously with the expansion of the plastic bottle, and at the same time, the elastic deformation of the second torsion spring provides a continuous contact force. This dynamic compensation mechanism avoids the mechanical constraint of traditional rigid clamping on the expansion deformation, eliminates the reverse binding force caused by the fixed clamping position. When the plastic bottle expands too much, through the limit of the ratchet and the ratchet teeth, the pressure wheel will not reset in time to press against the outer wall of the plastic bottle after expansion, and the plastic bottle can be limited within a certain range. The traditional clamping structure will generate a reverse binding force due to fixed limit during the expansion of the bottle body, which is superimposed on the detection pressure and affects the accuracy. The design of this solution allows the pressure wheel to dynamically adjust its position with the expansion through the irreversible rotation of the ratchet and the ratchet teeth, eliminates the additional stress generated by fixed clamping, ensures the purity of the detection load, and thus improves the detection accuracy;
[0019] By setting the cooperation of parts such as the arc-shaped inclined surface, when the auxiliary seat drives the plastic bottle to rotate, when the spherical rod contacts the arc-shaped inclined surface, under the action of the arc-shaped inclined surface, the auxiliary block is pushed to drive the auxiliary wheel to rotate towards the pressing block, so that the auxiliary wheel abuts against the back of the pressing block, thereby limiting the pressing block rotated to the lower part. In this way, when the compressive strength of a horizontal plastic bottle is detected, the pressing block at the bottom of the plastic bottle will not rotate, and it can be supported, so that the device can be applied to various detection methods, and thus improves the overall practicality of the device;
[0020] By setting the cooperation of parts such as the clamping component, there are two groups of clamping components, one group clamps an empty bottle, and the other group clamps a bottle filled with liquid. Since how the linear module drives the device to move is prior art, the specific driving structure is not drawn in this solution. After 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 can perform a pressing test on another plastic bottle filled with liquid. At the same time, when the device is detecting the compressive strength of another plastic bottle for the already detected plastic bottle, the staff can replace it, which will not affect the detection efficiency, so that the device can continuously detect, and thus improves the detection efficiency of the compressive strength of plastic bottles.

[0035] Refer to Figures 1 to 8, a multi-region compressive strength detection device for plastic bottles is provided, including: a detection table 1, and a detection pressure head 8 arranged above the detection table 1, with a driving component arranged between the detection table 1 and the detection pressure head 8;Auxiliary table 11 is arranged on the top of the detection table 1. A plastic bottle 21 is placed on the top of the auxiliary table 11. Clamping components are arranged on both sides of the plastic bottle 21 at the top of the detection table 1. The clamping components include two groups of rotating shafts 17 arranged on both sides of the plastic bottle 21. Each group of rotating shafts 17 has two, and multiple pressing blocks 18 are arranged on one side of each of the two rotating shafts 17. A pressing wheel 19 is fixedly connected to the inner side of the pressing block 18. An adaptive regulator is arranged between the rotating shaft 17 and the pressing block 18. The driving component includes a first linear module 2 fixedly connected to the top of the detection table 1. A sliding seat 3 is installed on the top of the first linear module 2. A support column 4 is fixedly connected to the top of the sliding seat 3. A support table 5 is fixedly connected to the top of the support column 4. A hydraulic cylinder 6 is installed on the top of the support table 5. The output end of the hydraulic cylinder 6 penetrates below the support table 5 and is fixedly connected to a connecting seat 7. A second linear module (not drawn in this solution) for driving the detection probe 8 to move longitudinally is installed at the bottom of the connecting seat 7. A fixed sleeve 9 is fixedly connected to the bottom of the connecting seat 7. A guiding rod 10 is fixedly connected to the top of the sliding seat 3. A through groove matching the guiding rod 10 is opened inside the fixed sleeve 9. The connecting seat 7 is slidably connected to the guiding rod 10 through the fixed sleeve 9. The clamping component includes an auxiliary seat 13 arranged above the detection table 1. A vertical seat 14 is fixedly connected to the top of the auxiliary seat 13. The two rotating shafts 17 are rotatably connected inside the vertical seat 14. A second driving motor 16 is installed on the top of the vertical seat 14. The output end of the second driving motor 16 is fixedly connected to one of the rotating shafts 17. A first straight gear 20 is fixedly connected to the outer wall of each of the two rotating shafts 17. The two first straight gears 20 are meshed. The adaptive regulator includes multiple second fixing seats 28 fixedly connected to the outer wall of the rotating shaft 17. Each second fixing seat 28 is arranged above one of the pressing blocks 18. A first rotating shaft 26 is fixedly connected to the top of the pressing block 18. One end of the first rotating shaft 26 penetrates above the second fixing seat 28 and is rotatably connected to the second fixing seat 28. A ratchet 27 is fixedly connected to the outer wall of the first rotating shaft 26. A second torsion spring 35 is installed between the ratchet 27 and the second fixing seat 28. The adaptive regulator further includes a second rotating shaft 32 rotatably connected to the top of the second fixing seat 28. A ratchet tooth 42 meshing with the ratchet 27 is fixedly connected to the outer wall of the second rotating shaft 32. A first torsion spring 33 is installed between the ratchet tooth 42 and the second fixing seat 28. A reset driving unit is arranged between the second rotating shaft 32 and the top of the auxiliary seat 13. A limiting component for limiting the pressing block 18 is arranged on the top of the auxiliary seat 13. The reset driving 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. Multiple arc-shaped racks 25 are fixedly connected to the outer wall of the U-shaped frame 24. Each arc-shaped rack 25 is correspondingly arranged on one side of one of the second fixing seats 28. A second straight gear 34 meshing with the arc-shaped rack 25 is fixedly connected to the outer wall of the second rotating shaft 32;
[0036] 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;
[0037] 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.
[0038] 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.
[0039] 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 be always attached to the outer wall of the plastic bottle 21 under the action of the second torsion spring 35;
[0040] As the pressing wheel 19 moves outward synchronously with the expansion of the plastic bottle 21, and at the same time, a continuous contact force is provided through the elastic deformation of the second torsion spring 35. This dynamic compensation mechanism avoids the mechanical constraint of traditional rigid clamping on the expansion deformation, eliminates the reverse binding force caused by the fixed clamping position. When the plastic bottle 21 expands over a large range, through the limit of the ratchet 27 and the ratchet teeth 42, the pressing wheel 19 will not reset in time to press against the outer wall of the plastic bottle 21 after expansion, and the plastic bottle 21 can be limited within a certain range. The traditional clamping structure will generate a reverse binding force due to fixed limit during the expansion of the bottle body, which is superimposed on the detected pressure and affects the accuracy. The design of this solution allows the pressing wheel 19 to dynamically adjust its position with the expansion through the irreversible rotation of the ratchet 27 and the ratchet teeth 42, eliminates the additional stress generated by fixed clamping, ensures the purity of the detected load, and thus improves the detection accuracy;
[0041] When the output end of the second drive motor 16 drives the pressing wheel 19 to expand and reset, during the rotation of the rotating shaft 17, the second spur gear 34 is driven to reset. When the second spur gear 34 contacts the arc-shaped rack 25, the ratchet teeth 42 are driven by the arc-shaped rack 25 to separate from the ratchet 27, so that the second torsion spring 35 is no longer driven by an external force to automatically reset the pressing wheel 19, so that the device can be used continuously.
[0042] Refer to Figures 1 to 8 , a flipping assembly for driving the clamping assembly to flip is arranged on the top of the detection table 1. The flipping assembly includes a first fixed seat 12 fixedly connected to the top of the detection table 1. A first drive motor 15 is installed on one side of the first fixed seat 12. The output end of the first drive motor 15 is connected to a coupling shaft 29, and one end of the coupling shaft 29 penetrates to the outside of the first fixed seat 12 and is fixedly connected to an auxiliary seat 13. The coupling shaft 29 is rotatably connected to the first fixed seat 12. The limiting assembly includes a rectangular sliding rod 37 slidably connected inside the vertical seat 14. One end of the rectangular sliding rod 37 penetrates to the outside of the vertical seat 14 and is fixedly connected to an auxiliary block 31. A connecting spring 36 is installed between the auxiliary block 31 and the vertical seat 14. One side of the auxiliary block 31 is fixedly connected to a power rod 22. One end of the power rod 22 is fixedly connected to a connecting rod 23. One end of the connecting rod 23 is fixedly connected to a plurality of U-shaped frames 24, and each U-shaped frame 24 is arranged on one side of a pressing block 18. An auxiliary wheel 40 is rotatably connected inside the U-shaped frame 24. The limiting assembly further includes a spherical rod 38 fixedly connected to one end of the auxiliary block 31. A circular 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 circular block 30;
[0043] A limiting component is provided on one side above an auxiliary seat 13. Therefore, only the pressing block 18 with the position adjusted downward is limited, and the other one is in normal use. When the side compressive strength of the plastic bottle 21 needs to be detected, an electric push rod (not shown in the figure) for driving the auxiliary table 11 to move downward is installed inside the detection table 1. First, the auxiliary table 11 is driven by the electric push rod to contract into the detection table 1, and then two first driving motors 15 can be started. The output end of the first driving motor 15 drives the coupling shaft 29 to drive the auxiliary seat 13 to rotate, so as to adjust the plastic bottle 21 to a horizontal position. The detection pressure head 8 can respectively detect the compressive strength of the plastic bottle 21 in a horizontal state at different positions under the action of the linear module;
[0044] The auxiliary wheel 40 is initially arranged on the side far from the pressing block 18. When the auxiliary seat 13 drives the plastic bottle 21 to rotate, when the spherical rod 38 contacts the arc-shaped inclined surface 39, under the action of the arc-shaped inclined surface 39, the auxiliary block 31 is pushed to drive the auxiliary wheel 40 to rotate towards the pressing block 18, so that the auxiliary wheel 40 abuts against the back of the pressing block 18, thereby limiting the pressing block 18 rotated to the lower side. In this way, when the compressive strength of the horizontal plastic bottle 21 is detected, the pressing block 18 at the bottom of the plastic bottle 21 will not rotate, so as to support it, making the device applicable to various detection methods, and thus improving the overall practicability of the device.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
