Description

Technical Field

[0001] This utility model relates to the field of material testing technology, and in particular to a device for testing the hardness of the bottom of a beverage can. Background Technology

[0002] As a common packaging container, the hardness of the bottom of an aluminum can is one of the important indicators for measuring its quality.

[0003] Currently, aluminum cans are usually placed directly on the test bench. The bottom of the can is prone to sliding or tilting when under pressure, causing the test results to deviate from the actual performance.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a device for testing the hardness of the bottom of a beverage can to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a device for detecting the hardness of the bottom of an aluminum can, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for testing the hardness of the bottom of an aluminum can includes a base frame. The base frame has multiple evenly distributed first grooves, each containing a second groove. A first sliding plate is slidably connected to the inner wall of each first groove. Second sliding plates are fixedly connected to both sides of each first sliding plate, and the second sliding plates are slidably connected to the inner wall of the second groove. A thrust assembly is provided between the multiple first sliding plates. A clamping plate is fixedly connected to each first sliding plate, and the clamping plates cooperate to clamp the side wall of the aluminum can. A support frame is also fixedly connected to the top plate of the base frame. A cylinder is fixedly connected to the support frame, and a spherical indenter hardness tester is fixedly connected to the drive end of the cylinder.

[0008] In a further technical solution, multiple uniformly distributed strip grooves are provided on the side of the multiple clamping plates that are close to each other, and friction strips are fixedly connected in each of the strip grooves.

[0009] In a further technical solution, the thrust assembly includes a motor, a base, a connecting plate, and a rotating plate; a motor is fixedly connected to the lower end of the base frame top plate, and a connecting plate is fixedly connected to the drive end of the motor; a base is fixedly connected to the lower end of each first slide plate, and a rotating plate is rotatably connected between the base and the connecting plate.

[0010] A further technical solution is that a base plate is fixedly connected to the bottom of the base frame, and a plurality of evenly distributed guide rods are fixedly connected between the base plate and the top plate of the base frame, and all the guide rods are slidably connected to the connecting plate.

[0011] A further technical solution is that the first skateboard and the two corresponding second skateboards are integrally molded structures.

[0012] In a further technical solution, all the clamping plates are arc-shaped, and multiple clamping plates are concentric.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. By controlling the extension of the motor, the motor drives the connecting plate to descend. Then, the connecting plate drives multiple rotating plates to move. Subsequently, the rotating plates drive the first sliding plate to slide along the inner wall of the first sliding groove via the base. Then, the multiple first sliding plates drive the clamping plates to move closer to each other, thereby fixing and clamping the can. The cylinder drives the spherical indenter hardness tester to descend. Then, the spherical indenter hardness tester squeezes the bottom of the can, thereby performing hardness testing on the can. This effectively prevents the bottom of the can from sliding or tilting under pressure, thereby improving the accuracy of the test results.

[0015] 2. Friction strips are fixedly connected inside the groove, thereby increasing the friction between the clamping plate and the can, thus improving the stability of the clamping plate in holding the can.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-3 As shown, this utility model embodiment provides a device for testing the hardness of the bottom of an aluminum can, including a base frame 1. The base frame 1 has multiple evenly distributed first sliding grooves 2, each containing a second sliding groove 3. A first sliding plate 4 is slidably connected to the inner wall of each first sliding groove 2. Second sliding plates 5 are fixedly connected to both sides of each first sliding plate 4, and the second sliding plates 5 are slidably connected to the inner wall of the second sliding groove 3. A thrust assembly 12 is provided between the multiple first sliding plates 4, controlling the multiple first sliding plates 4 to move closer or further apart. A clamping plate 6 is fixedly connected to each first sliding plate 4, and the clamping plates 6 cooperate to clamp the side wall of the aluminum can. A support frame 7 is also fixedly connected to the top plate of the base frame 1. A cylinder 8 is fixedly connected to the support frame 7, and a spherical indenter hardness tester 9 is fixedly connected to the drive end of the cylinder 8. The hardness of the bottom of the aluminum can is measured by the cooperation of the cylinder 8 and the spherical indenter hardness tester 9.

[0024] Furthermore, the first skateboard 4 and the two corresponding second skateboards 5 are integrally molded structures.

[0025] Furthermore, all of the clamping plates 6 are arc-shaped, and multiple clamping plates 6 are concentric.

[0026] Furthermore, each of the clamping plates 6 has a plurality of evenly distributed strip grooves 10 on its side that is close to each other, and each strip groove 10 is fixedly connected with a friction strip 11 to increase the friction between the clamping plate 6 and the can.

[0027] like Figure 2 and Figure 3 As shown, the thrust assembly 12 includes a motor 121, a base 122, a connecting plate 123, and a rotating plate 124; the motor 121 is fixedly connected to the lower end of the top plate of the base frame 1, the driving end of the motor 121 is fixedly connected to the connecting plate 123, the lower end of each first slide plate 4 is fixedly connected to the base 122, and the rotating plate 124 is rotatably connected between the base 122 and the connecting plate 123.

[0028] Furthermore, a base plate 126 is fixedly connected to the bottom of the base frame 1, and a plurality of evenly distributed guide rods 125 are fixedly connected between the base plate 126 and the top plate of the base frame 1, and the guide rods 125 are all slidably connected to the connecting plate 123.

[0029] In a specific application, the motor 121 is controlled to extend and retract, and then the motor 121 drives the connecting plate 123 to rise and fall. After that, the connecting plate 123 drives the rotating plate 124 to move, and then the rotating plate 124 drives the first slide plate 4 to slide along the inner wall of the first slide groove 2 through the base 122.

[0030] In this embodiment of the invention, by controlling the extension of the motor 121, the motor 121 drives the connecting plate 123 to descend. Then, the connecting plate 123 drives multiple rotating plates 124 to move. Subsequently, the rotating plates 124 drive the first sliding plate 4 to slide along the inner wall of the first sliding groove 2 via the base 122. Then, the multiple first sliding plates 4 respectively drive the clamping plates 6 to move closer to each other, thereby fixing and clamping the can. The cylinder 8 drives the spherical indenter hardness tester 9 to descend. Then, the spherical indenter hardness tester 9 presses the bottom of the can, thereby performing hardness testing on the can. This effectively prevents the bottom of the can from sliding or tilting under pressure, thereby improving the accuracy of the test results. A friction strip 11 is fixedly connected in the strip groove 10, thereby increasing the friction between the clamping plate 6 and the can, thereby improving the stability of the clamping plate 6 clamping the can.

[0031] The working principle of this utility model is as follows: A can with a bottom is placed on a base frame 1, and then the motor 121 is extended. The motor 121 then drives the connecting plate 123 to rise and fall. After that, the connecting plate 123 drives multiple rotating plates 124 to move. Then, the rotating plates 124 drive the first sliding plate 4 to slide along the inner wall of the first sliding groove 2 towards the axis of the connecting plate 123 through the base 122. The first sliding plate 4 drives the clamping plate 6 to move until the multiple clamping plates 6 are in contact with the can, thereby fixing the bottom of the can. Then, the cylinder 8 is extended, and the cylinder 8 drives the spherical indenter hardness tester 9 to squeeze the bottom of the can, thereby performing hardness testing on the can.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
