Description

Technical Field

[0001] This utility model relates to the field of packaging measurement technology, specifically to a portable packaging barrel wall thickness measuring device. Background Technology

[0002] During the production of packaging barrels, the thickness varies between different batches or even between different products in the same batch due to the influence of process parameters such as injection molding machines, molds, temperature, speed, and pressure. If these variations are not monitored and adjusted in a timely manner through testing and measurement, the thickness will exceed the tolerance, resulting in products that do not meet performance requirements and a decrease in the pass rate.

[0003] Currently, the common method is to cut packaging barrels into four equal parts, select two diagonally opposite sections, and measure the thickness using a micrometer. This method requires damaging the packaging barrel, making it difficult to monitor during production. Furthermore, the cutting operation is still done manually, which is not only labor-intensive and increases workload but also poses certain safety risks to operators. Most importantly, when measuring the same location with a micrometer, the results are inconsistent each time, lacking repeatability. Therefore, it is necessary to design a packaging barrel wall thickness measuring device to accurately, conveniently, and quickly measure the wall thickness of packaging barrels and monitor the packaging thickness during production. This would ensure that the packaging barrels do not exceed tolerances and that the mold core does not have eccentricity issues, while also being portable. Summary of the Invention

[0004] To address the technical problems of existing technologies that require damaging the barrel to measure the wall thickness of packaging barrels, are time-consuming and labor-intensive, and lack repeatability, this application proposes a portable packaging barrel wall thickness measuring device, which solves the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides a portable packaging barrel wall thickness measuring device, comprising: a measuring rod, which is horizontally arranged and has a scale on its body; a slider that can move linearly along the extension direction of the measuring rod is fitted on the measuring rod; after the measuring rod is inserted into the packaging barrel, the side wall of the slider abuts against the wall thickness at the opening of the packaging barrel; a gripping rod, which is fixedly connected to the measuring rod, and the extension direction of the gripping rod is the same as the extension direction of the measuring rod; when the measuring rod is inserted into the packaging barrel, the gripping rod moves to the outside of the corresponding packaging barrel; and a thickness gauge, which includes a pressure gauge assembly and a receiving ball, wherein the receiving ball is disposed at the end of the measuring rod that is inserted into the packaging barrel, the receiving ball is arranged at the zero mark of the measuring rod and abuts against the inner wall of the packaging barrel; the pressure gauge assembly includes a dial fixed to the gripping rod and a pressure rod that moves linearly along the vertical direction on the dial; the pressure rod falls directly opposite the receiving ball under the action of gravity and presses against the outer wall of the packaging barrel.

[0007] Furthermore, a clamping assembly is provided at one end of the slider near the gripping rod. The clamping assembly includes a clamping rod and an abutment block. The abutment block is fixed on the side wall of the slider that contacts the packaging barrel and abuts against the inner wall of the packaging barrel. The clamping rod is movably disposed on the end face of the slider and is connected to the slider body by a tension spring. After being bent twice, the clamping rod forms a clamping part at the hook that clamps against the outer wall of the packaging barrel. The clamping part is positioned opposite to the abutment block.

[0008] Furthermore, the measuring rod and the gripping rod are integrally formed from the same material body, and the material body is bent twice to form the measuring rod and the gripping rod arranged in parallel.

[0009] Furthermore, it also includes an assembly frame, which includes a base and a vertical connecting rod, wherein the measuring rod and the gripping rod are detachably connected to the connecting rod.

[0010] Furthermore, the connecting rod is provided with a positioning block that is abutted against by the falling surfaces of the corresponding measuring rod and the gripping rod.

[0011] Furthermore, the pressure rod extends through the dial, and the end of the pressure rod away from the receiving ball forms a limiting block that prevents the pressure rod from dislodging from the dial. At the same time, a rotatable lever is provided on the dial, and the lever lifts the pressure rod by moving the limiting block.

[0012] Furthermore, the end of the pressure rod near the receiving ball is formed as a probe with a spherical surface.

[0013] Furthermore, the gripping bar has gripping grooves formed for gripping.

[0014] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0015] This utility model discloses a portable packaging barrel wall thickness measuring device. After the measuring rod is inserted into the packaging barrel, the axial distance of the point to be measured relative to the barrel opening can be read through the scale on the measuring rod. During the process, the slider slides on the measuring rod until it abuts against the wall thickness at the barrel opening, thereby assisting in reading the scale on the measuring rod. When measuring the thickness of the point to be measured, the receiving ball of the thickness gauge abuts against the inner wall of the packaging barrel. Under the action of gravity, the pressure rod falls directly opposite the receiving ball and presses against the outer wall of the packaging barrel. The thickness of this measuring point is displayed on the dial, thereby accurately, conveniently, and quickly confirming whether the wall thickness exceeds the tolerance. After the axial distance of the measuring point relative to the barrel opening is determined by the measuring rod, the packaging barrel can be rotated to measure the barrel wall thickness of multiple measuring points at the same height of the packaging barrel. By comparing the barrel wall thickness values ​​of multiple measuring points on the same circle, it can be confirmed whether the barrel wall thickness is uniform and whether there is any eccentricity in the mold core. This solves the technical problems of existing packaging barrel wall thickness measurement, which requires damage to the barrel body, is time-consuming and laborious, and lacks repeatability.

The gripping rod 2 is fixedly connected to the measuring rod 1, and the extension direction of the gripping rod 2 is the same as the extension direction of the measuring rod 1. When the measuring rod 1 is inserted into the packaging barrel a, the gripping rod 2 moves to the outside of the corresponding packaging barrel a.

The pressure gauge assembly includes a dial 32 fixed on the gripping rod 2 and a pressure rod 33 that moves linearly along the vertical direction on the dial 32. Under the action of gravity, the pressure rod 33 falls directly onto the ball 31 and presses against the outer wall of the packaging barrel a, thereby displaying the wall thickness value of the packaging barrel a at this measurement point on the dial 32. It should be noted that the wall thickness of the packaging barrel a is measured by comparing the wall thickness values ​​of the entire circumference of the packaging barrel a at the same height to confirm whether the wall thickness is uniform and to confirm whether the mold core used to make the packaging barrel a is off-center.

[0027] In a preferred embodiment of this utility model, a clamping assembly 12 is provided at one end of the slider 11 near the gripping rod 2. The clamping assembly 12 includes a clamping rod 13 and an abutment block 14.

After being bent twice, the clamping rod 13 forms a clamping part 131 at the hook that clamps the outer wall of the packaging barrel a. The clamping part 131 is positioned opposite to the abutment block 14. The clamping assembly 12 can better fix the measuring device on the packaging barrel a, thereby facilitating measurement.

[0028] In a preferred embodiment of this utility model, the measuring rod 1 and the gripping rod 2 are integrally formed from the same material body, and the material body is bent twice to form the measuring rod 1 and the gripping rod 2 arranged in parallel.

The measuring rod 1 and the gripping rod 2 can be detachably connected to the connecting rod 42. Specifically, the measuring rod 1 and the gripping rod 2 can be assembled to the connecting rod 42 by screwing.

[0030] Furthermore, the connecting rod 42 is equipped with a positioning block 43 that is abutted against by the falling surfaces of the corresponding measuring rod 1 and gripping rod 2, simplifying installation.

[0031] In a preferred embodiment of this utility model, the pressure rod 33 passes through the dial 32, and the end of the pressure rod 33 away from the receiving ball 31 forms a limiting block 331 that prevents the pressure rod 33 from coming off the dial 32. At the same time, a rotatable lever 34 is provided on the dial 32, and the lever 34 lifts the pressure rod 33 by moving the limiting block 331.

[0032] In a preferred embodiment of this utility model, the end of the pressure rod 33 near the receiving ball 31 is formed as a probe with a spherical surface to better fit the outer wall of the packaging barrel a.
