Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a detection device for the opening of a container. Background Technology

[0002] In the production process of containers made of various plastics, metals, or composite materials (such as thermos cups), in order to ensure the sealing of the container lid or interface, one or more annular "water-sealing ribs" (also known as sealing ribs) are usually designed on the inside of the container opening. The quality indicators such as the dimensional accuracy, continuity, and absence of defects of the water-sealing ribs directly determine the sealing performance of the container and are key characteristics that must be strictly monitored during the production process. However, at present, the detection of "water-sealing ribs" generally suffers from problems such as "unclear visibility, inaccurate measurement, low efficiency, and difficulty in quantification," so improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies, such as the inconvenience of detecting the "sealing ribs" of containers, by providing a new detection device for the opening of containers.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A detection device for the opening of a container includes a container and a detection device located on the upper end of the container. The detection device includes a base that engages with the opening of the container. A support frame located at the upper end of the base; A positioning component is located in the middle of the base and can move up and down on the base. The lower end of the positioning component can extend into the container and cooperate with the inner wall of the container. A measuring device is mounted on the support frame and located directly above the positioning component. The measuring device engages with the upper end of the positioning component to perform detection.

[0005] This application achieves overall device fixation by cooperating with the base and the container opening. The positioning component extends into the container and fits against the inner wall, which can accurately align with the key area where the water sealing rib is located. The measuring device is located directly above the positioning component and cooperates with it, which can convert the size deviation and continuity defects of the water sealing rib into readable measurement data for easy detection.

[0006] Preferably, in the above-described detection device for the opening of a container, the base is provided with a fixed notch, and the support frame is provided with a fixed step, wherein the support frame is limited by the fixed step and the fixed notch cooperating with each other.

[0007] By using fixed notches and fixed steps, the assembly difficulty for operators can be effectively reduced, while the limiting structure can assist in subsequent fixing steps and improve the overall assembly efficiency.

[0008] Preferably, in the above-described detection device for the mouth of a container, the support frame has at least one first fixing hole, and the base has a second fixing hole at a position corresponding to the first fixing hole. The first fixing hole of the support frame and the second fixing hole of the base are connected by a first bolt.

[0009] The support frame and base are detachable by the first bolt, which facilitates subsequent disassembly, maintenance or adjustment of the device and extends the service life of the testing device.

[0010] Preferably, in the above-described detection device for the opening of a container, the positioning component includes a connecting end and a mating end. The base has a movable hole, the connecting end is located in the movable hole and can move up and down in the movable hole, and the mating end extends into the container and mates with the inner wall of the container.

[0011] The connecting end can move up and down within the movable hole, allowing the insertion depth of the positioning component to be adjusted according to the container height and the position of the sealing rib. This eliminates the need to customize positioning components for different container sizes, thus improving the device's versatility.

[0012] Preferably, the detection device for the container opening described above further includes a fixing pin, and a third fixing hole is provided on the connecting end. The fixing pin cooperates with the third fixing hole to prevent the connecting end from disengaging from the movable hole.

[0013] The fixing pin only restricts the positioning component from "detaching" and does not affect the normal up-and-down movement function of the positioning component. While ensuring safety, it can still adapt to the testing needs of different containers.

[0014] Preferably, in the above-described detection device for the mouth of a container, the support frame is further provided with a fourth fixing hole, the lower end of the measuring device extends through the fourth fixing hole, and the measuring rod of the measuring device is engaged with the upper surface of the connecting end.

[0015] The fourth fixing hole is used for mounting the measuring instrument, and the measuring rod directly contacts the upper surface of the connecting end. Therefore, the slight displacement of the positioning component caused by the change in the mass of the water sealing rib can be directly transmitted to the measuring instrument, thereby making the measuring instrument reading respond quickly.

[0016] Preferably, the above-described detection device for the container opening further includes a second bolt, and the support frame is provided with a fifth fixing hole. The second bolt passes through the fifth fixing hole and is then fixed to the lower end of the measuring device.

[0017] The measuring instrument can be firmly locked to the support frame by the second bolt to prevent it from shifting or shaking due to vibration during the test, thus avoiding reading fluctuations and ensuring the reliability of test data from multiple batches.

[0018] The present invention has the following advantages through the above structural improvements: This application has the advantage of convenient testing of "water-sealing strips", among which: 1) By using the precise internal positioning of the positioning component and the quantitative reading of the measuring instrument, the core problems of traditional testing, such as "unclear visibility, inaccurate measurement, and difficulty in quantification", are completely overcome, enabling objective quantitative judgment of quality indicators such as the size and continuity of the sealing strip, and improving the reliability of the test results; 2) The overall structural design takes into account "rapid assembly, rapid testing, and rapid maintenance". The base and container opening can be quickly matched, the positioning components can move flexibly, and the measuring instrument readings are intuitive, which greatly shortens the testing time of a single container. It can be integrated into the production line and improve the overall production efficiency. 3) The movable design and detachable connection of the positioning components allow them to be adapted to containers of different sizes, eliminating the need to customize equipment for a single product and reducing upfront investment costs; at the same time, the modular design facilitates component maintenance and replacement, reducing long-term usage costs.

[0021] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a detection device for the opening of a container includes a container 1 and a detection device 2 located on the upper end of the container 1. The detection device 2 includes a base 21, which cooperates with the opening of the container 1. Support frame 22, which is located at the upper end of the base 21; Positioning component 23, which is located in the middle of the base 21 and can move up and down on the base 21. The lower end of the positioning component 23 can extend into the container 1 and cooperate with the inner wall of the container 1. Measuring device 24 is disposed on the support frame 22 and located directly above the positioning component 23. The measuring device 24 cooperates with the upper end of the positioning component 23 to perform detection.

[0023] Preferably, the base 21 is provided with a fixing notch 211, and the support frame 22 is provided with a fixing step 221. The support frame 22 is limited by the cooperation between the fixing step 221 and the fixing notch 211.

[0024] Specifically, the interlocking of the fixed notch 211 and the fixed step 221 enables the "pre-positioning" of the support frame 22 and the base 21, ensuring that their relative positions are unique and preventing misalignment of the measuring instrument 24 and the positioning component 23 due to assembly offset. This reduces measurement errors from the source and prevents lateral displacement of the support frame 22 and the base 21 during the testing process, avoiding positioning offset caused by vibration and collision, and ensuring the consistency of test data from multiple batches.

[0025] Preferably, the support frame 22 is provided with at least one first fixing hole 222, and the base 21 is provided with a second fixing hole 212 at a position corresponding to the first fixing hole 222. The first fixing hole 222 of the support frame 22 and the second fixing hole 212 of the base 21 are connected by a first bolt 3.

[0026] Furthermore, the tightness of the connection through the first bolt 3 is much higher than that of a simple limiting structure, which can completely eliminate the relative loosening of the support frame 22 and the base 21 during the detection process, ensuring the stability of the position of the measuring device 24 and further guaranteeing the measurement accuracy.

[0027] Preferably, the positioning component 23 includes a connecting end 231 and a mating end 232. The base 21 has a movable hole 213. The connecting end 231 is located in the movable hole 213 and can move up and down in the movable hole 213. The mating end 232 extends into the container 1 and mates with the inner wall of the container 1.

[0028] Specifically, the mating end 232 extends into the interior of container 1 and fits against the inner wall to achieve "internal reference positioning". Compared with the external positioning method, it is closer to the water sealing rib area, avoiding positioning deviation caused by deformation of the opening of container 1. It ensures that the measurement data is directly related to the actual quality of the water sealing rib. Furthermore, the movable structure design does not hinder the placement and removal of container 1. The positioning component 23 can automatically adjust its position as container 1 is placed, without the need for additional manual adjustment steps, which fits the rhythm of rapid testing on the production line.

[0029] Preferably, the detection device 2 further includes a fixing pin 25, and a third fixing hole 2311 is provided on the connecting end 231. The fixing pin 25 cooperates with the third fixing hole 2311 to prevent the connecting end 231 from disengaging from the movable hole 213.

[0030] Specifically, when the fixing pin 25 is inserted into the third fixing hole 2311, it can limit the maximum travel of the connecting end 231 in the movable hole 213, preventing it from detaching from the base 21 due to improper operation, thus preventing detection interruption, equipment damage or safety hazards.

[0031] Preferably, the support frame 22 is also provided with a fourth fixing hole 223, the lower end of the measuring device 24 passes through the fourth fixing hole 223, and the measuring rod of the measuring device 24 is engaged with the upper surface of the connecting end 231.

[0032] Specifically, the fourth fixing hole 223 guides the measuring device 24, ensuring that the measuring rod of the measuring device 24 is perpendicularly attached to the upper surface of the connection end 231 of the positioning component 23, avoiding reading errors caused by measurement angle deviation, and maximizing the accuracy advantage of the measuring device. Furthermore, the measuring instrument 24 is a dial indicator.

[0033] Preferably, a second bolt 4 is also included, and a fifth fixing hole 224 is also provided on the support frame 22. The second bolt 4 passes through the fifth fixing hole 224 and is then fixed to the lower end of the measuring device 24.

[0034] Specifically, the removable design of the second bolt 4 allows for convenient periodic disassembly of the measuring instrument 24 for accuracy calibration, or quick replacement of the measuring instrument 24 if it is damaged, ensuring that the measuring instrument 24 is always in a precise state.

[0035] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
