Description

Technical Field

[0001] This utility model relates to the field of plastic bottle testing technology, and in particular to a plastic bottle testing device. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded into plastic containers through blow molding, extrusion blow molding, or injection molding.

[0003] However, existing plastic bottles are easily damaged by impacts during transportation after processing. If the plastic bottles are of poor quality, they are prone to breakage upon impact. Once a plastic bottle breaks, the internal liquid will leak during subsequent filling, resulting in additional economic and resource losses. Therefore, it is necessary to provide a plastic bottle inspection device to perform quality inspection on processed plastic bottles. Utility Model Content

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model provides a plastic bottle testing device, such as... Figure 1-3 As shown, the plastic bottle testing equipment includes: a water tank 1, with multiple support frames 2 fixedly installed on the bottom inner wall of the water tank 1, and the same support plate 3 fixedly installed on the multiple support frames 2. The support plate 3 has an opening, and a wire mesh 4 is fixedly installed on the inner wall of the opening; two vertical plates 5 welded to the top of the support plate 3, and a same limiting ring 6 for placing plastic bottles is fixedly installed between the two vertical plates 5; two impact mechanisms for impact testing of plastic bottles, respectively installed on the two vertical plates 5; and a water injection mechanism for leak testing of plastic bottles, assembled on the water tank 1 and one of the vertical plates 5.

[0021] In this embodiment, the device includes a water tank 1. A support plate 3 is fixedly supported on the inner wall of the bottom of the water tank 1 by multiple support frames 2. A wire mesh 4 is fixed to the inner wall of an opening in the support plate 3. The wire mesh 4 supports the plastic bottle and prevents leakage. Two vertical plates 5 are welded to the top of the support plate 3. A limiting ring 6 is fixedly installed between the two vertical plates 5. The limiting ring 6 is used to place the plastic bottle to be tested, restricting it to a specific position for subsequent testing. Impact mechanisms are installed on the two vertical plates 5 respectively. During testing, the two impact mechanisms can impact the plastic bottle placed within the limiting ring 6. By observing the state of the plastic bottle after the impact, it can be observed whether it breaks and the degree of deformation, etc. To effectively assess the impact resistance of plastic bottles, a water injection mechanism is installed on water tank 1 and one of the vertical plates 5. After the impact test on the plastic bottle, the water injection mechanism can pump water from water tank 1 into the plastic bottle. Then, the plastic bottle is observed again to see if any water leaks out, i.e., a leak test is performed. If the plastic bottle leaks after water injection, it indicates that the plastic bottle is substandard. If it does not leak, it indicates that the plastic bottle passes the leak test. By combining the impact test and the leak test, the quality of the plastic bottle can be comprehensively evaluated. After the test is completed, the plastic bottle can be removed, and the water can be poured back into water tank 1 so that the water can be reused.

[0022] In a further preferred embodiment of the present invention, the impact mechanism includes: a housing 7 fixedly installed on the vertical plate 5, a cylinder 8 fixedly installed on the inner wall of the housing 7, a push plate 9 fixedly installed on the output rod of the cylinder 8, and a plurality of collision blocks 10 fixedly installed on the push plate 9.

[0023] In this embodiment, the impact mechanism is used to perform impact detection on the plastic bottle. When it is necessary to perform impact detection on the plastic bottle placed in the limiting ring 6, the cylinder 8 is activated, and its output rod extends to push the push plate 9 towards the plastic bottle, thereby driving multiple collision blocks 10 to impact the plastic bottle. This can simulate the collision situation of the plastic bottle, thereby testing the impact resistance of the plastic bottle, observing the state of the plastic bottle after the impact, and seeing whether it breaks or has cracks, to determine whether its quality is qualified.

[0024] In a further preferred embodiment of this utility model, the water injection mechanism includes: a servo motor 11 fixedly installed on one of the vertical plates 5, a connecting pipe 12 fixedly installed on the output shaft of the servo motor 11, and a nozzle 13 provided on the connecting pipe 12; a water pump 14 fixedly installed on the inner wall of the bottom of the water tank 1, a delivery pipe 15 fixedly installed on the drain end of the water pump 14, and one end of the delivery pipe 15 extending to the outside of the water tank 1; and a flexible hose 16 fixedly installed at one end of the delivery pipe 15, one end of the flexible hose 16 being fixedly connected to one end of the connecting pipe 12.

[0025] In this embodiment, the water injection mechanism is used to perform a leak detection on the plastic bottle. During the detection, the servo motor 11 is started, driving the connecting pipe 12 to rotate half a turn, so that the nozzle 13 is aligned with the bottle mouth of the plastic bottle placed in the limiting ring 6. Then, the water pump 14 is started. When the water pump 14 is working, it will deliver water to the hose 16 through the delivery pipe 15. The hose 16 delivers water to the connecting pipe 12, and finally sprays it out from the nozzle 13 and injects it into the plastic bottle. After the water injection is completed, it is observed whether there is any water leakage from the plastic bottle body, that is, to perform a leak detection. If the plastic bottle leaks after water injection, it means that the quality of the plastic bottle is unqualified. If there is no leakage, it means that the plastic bottle is qualified in terms of leak detection. After the detection, the servo motor 11 reverses half a turn, driving the connecting pipe 12 and the nozzle 13 to reset, so as to avoid affecting subsequent detection or other operations.

[0026] In a further preferred embodiment of this utility model, a drain pipe is fixedly installed on one side of the water tank 1, and a valve is provided on the drain pipe.

[0027] In this embodiment, by using a valve, water in water tank 1 can be discharged from the drain pipe when needed.

[0028] In a further preferred embodiment of this utility model, the wire mesh 4 is made of stainless steel and is used to support the plastic bottle.

[0029] In this embodiment, the use of wire mesh 4 not only supports the bottom of the plastic bottle, but also allows water droplets leaking from the plastic bottle during the testing process to fall into the water tank 1.

[0030] In a further preferred embodiment of this utility model, the two vertical plates 5 are symmetrically arranged, and both vertical plates 5 are made of metal material.

[0031] In this embodiment, the vertical plate 5 made of metal material has high strength and stability, and can withstand the impact force generated by the impact mechanism during the detection process.

[0032] In a further preferred embodiment of the present invention, a water pump pipe is fixedly installed on the water inlet end of the water pump 14, and the water pump pipe is configured as L-shaped.

[0033] In this embodiment, the L-shaped water pipe design allows it to get closer to the bottom of the water tank 1, thereby more effectively drawing water from the water tank 1 and making the water extraction more thorough.

[0034] In summary, compared with related technologies, this solution uses an impact mechanism to test the impact resistance of plastic bottles and a water injection mechanism to test for leaks. The combination of these two methods enables quality inspection of plastic bottles, effectively reducing the risk of breakage and leakage during transportation and subsequent use due to poor quality plastic bottles, thus reducing economic losses and resource waste.

[0035] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model.

Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
