[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] Example: Please refer to Figures 1 to 5 The present embodiment provides a bowl film opening force testing device, including a base 1, on which a placing component 3 for placing a packaging bowl 2 to be tested is arranged, a mounting plate 4 is arranged above the base 1, and the mounting plate 4 is fixedly connected to the base 1 by a vertically arranged support rod 5, and a lifting component is arranged on the mounting plate 4, and a lifting part of the lifting component is movably arranged to pass through the mounting plate 4, and a clamping component is arranged on the lifting part of the lifting component, and the clamping component is used to clamp the bowl film on the packaging bowl 2 to be tested, and the lifting component can drive the clamping component to perform the required up and down movement.
[0027] In this embodiment, the lifting assembly includes a lifting cylinder 6, which is fixedly arranged on the top surface of the mounting plate 4. The piston rod end of the lifting cylinder 6 is vertically movable downward and penetrates the mounting plate 4. A horizontally arranged pressure plate 7 is arranged on the piston rod end of the lifting cylinder 6, and the clamping assembly is fixedly arranged on the bottom surface of the pressure plate 7.
[0028] In this embodiment, the clamping assembly includes a first clamping block 8 and a second clamping block 9. The first clamping block 8 is arranged above the second clamping block 9. A connecting groove 10 is opened at the middle position of the bottom surface of the first clamping block 8, and a connecting block 11 is arranged at the middle position of the top surface of the second clamping block 9. The connecting block 11 is movably connected to the connecting groove 10. The first clamping block 8 is also movably penetrated by a horizontally arranged torsion spring shaft 12, which is movably arranged to pass through the connecting groove 10. The shaft section of the torsion spring shaft 12 passing through the connecting groove 10 also passes through the connecting block 11 and is fixedly connected to the connecting block 11, so that when the torsion spring shaft 12 rotates, it can drive the second clamping block 9 to rotate accordingly, that is, through the setting of the torsion spring shaft 12, the second clamping block 9 can be hinged to the first clamping block 8. At the same time, the setting of the torsion spring shaft 12 satisfies that the first clamping block 8 and the second clamping block 9 can bite each other when the torsion spring shaft 12 is in a normal state.
[0029] Through the above arrangement, when testing the opening force of the bowl film of the packaging bowl 2 to be tested, the packaging bowl 2 to be tested is placed in the placement assembly 3, and then the lifting cylinder 6 is controlled to start working, so that the piston rod end of the lifting cylinder 6 moves downward, so that the pressing plate 7 can be pressed on the top surface of the packaging bowl 2 to be tested. Then, the first clamping block 8 and the second clamping block 9 are separated by bending the second clamping block 9, and the edge of the bowl film of the packaging bowl 2 to be tested is placed between the first clamping block 8 and the second clamping block 9, and the second clamping block 9 is released. The second clamping block 9 will be reset under the action of the torsion spring shaft 12, so as to cooperate with the first clamping block 8 to bite the edge of the bowl film of the packaging bowl 2 to be tested. Then, the lifting cylinder 6 is controlled to work, and the piston rod end of the lifting cylinder 6 moves upward, so that the pressure plate 7 moves away from the packaging bowl 2 to be tested. At this time, the clamping assembly makes the bowl film of the packaging bowl 2 to be tested open upward. Since the first clamping block 8 and the second clamping block 9 are connected by the torsion spring shaft 12, when cooperating to open the bowl film of the packaging bowl 2 to be tested, under the action of the torsion spring shaft 12, the first clamping block 8 and the second clamping block 9 are difficult to separate, so as to ensure the clamping effect. Then, by holding the packaging bowl 2 to be tested, when the clamping assembly opens the bowl film of the packaging bowl 2 to be tested upward, the bowl film opening force of the packaging bowl 2 to be tested can be obtained by reading the corresponding force value used by the lifting cylinder 6.
[0030] In order to facilitate the reading of the bowl film opening force, a gas pressure sensor 14 is arranged on the mounting plate 4. The gas pressure sensor 14 is connected to the lifting cylinder 6. The gas pressure sensor 14 can read the gas pressure inside the lifting cylinder 6 in real time. During the detection process, when the clamping component lifts up the bowl film of the packaging bowl 2 to be tested, the opening force of the bowl film of the packaging bowl 2 to be tested can be known by reading the pressure value detected by the gas pressure sensor 14 at this time.
[0031] In order to further improve the clamping effect of the clamping assembly on the edge of the bowl film of the packaging bowl 2 to be tested, the mutually engaging surfaces of the first clamping block 8 and the second clamping block 9 are provided with sawtooth-shaped engaging teeth 13. The setting of the engaging teeth 13 can prevent the bowl film of the packaging bowl 2 to be tested from slipping off between the first clamping block 8 and the second clamping block 9 easily, thereby ensuring the clamping effect.
[0032] For the convenience of the user, in this example, the placement assembly 3 includes a first placement seat 31 and a second placement seat 32. The first placement seat 31 is fixedly arranged on the top surface of the base 1, and the second placement seat 32 is fixedly arranged on the top surface of the first placement seat 31. The top and bottom of the second placement seat 32 are both open structures. The packaging bowl 2 to be tested is placed into the second placement seat 32 from the top of the second placement seat 32, and its bottom touches the top surface of the first placement seat 31. An air cavity 33 is provided inside the first placement seat 31, and a connecting hole 34 is provided on the top of the first placement seat 31. The air cavity 33 is connected to the second placement seat 32 through the connecting hole 34. An air pump 35 is also provided on the mounting plate 4, and the air pump 35 is connected to the air cavity 33 pipeline. Through the above-mentioned arrangement, when the packaging bowl 2 to be tested is placed in the second placement seat 32, the vacuum pump 35 is started to work, and the vacuum pump 35 evacuates air from the air cavity 33 through the corresponding connecting air pipe, so that the connecting hole 34 can generate suction on the bottom of the packaging bowl 2 to be tested, and the packaging bowl 2 to be tested in the second placement seat 32 can be fixed, so that the user does not need to hold the packaging bowl 2 to be tested during the detection process, which is convenient for the user to use.
[0033] Since the specifications of the packaging bowls 2 to be tested are different, in order to be applicable to the detection of packaging bowls 2 to be tested of different specifications, the inner diameter of the second placement seat 32 should be larger than the diameter of the packaging bowl 2 to be tested of the largest specification, so that all specifications of packaging bowls 2 to be tested can be placed in the first placement seat 31. At the same time, the aperture of the connecting hole 34 should be smaller than the diameter of the packaging bowl 2 to be tested of the smallest specification, so as to avoid the phenomenon that the bottom of the packaging bowl 2 to be tested falls into the connecting hole 34, which affects the fixing and adsorption effect of the connecting hole 34. Through the above settings, the testing device can be applicable to the detection of packaging bowls 2 to be tested of different specifications.
[0034] At the same time, in order to avoid the shaking of the packaging bowls 2 of different specifications in the second placement seat 32, thereby affecting the subsequent fixing and adsorption effect of the connecting hole 34 on them. The side walls of the second placement seat 32 are both threaded with adjusting screws 36, and the adjusting screws 36 on both sides are movably arranged to penetrate the corresponding side walls of the second placement seat 32. The ends of the adjusting screws 36 on both sides are close to each other, and the ends of the adjusting screws 36 on both sides are arranged to be far away from each other. With the above arrangement, when the packaging bowl 2 to be tested is placed in the second placement seat 32, the penetration amount of the adjusting screws 36 can be adjusted by rotating the adjusting handle 38, so that the pressing blocks 37 on both sides play a role of limiting the side walls of the packaging bowl 2 to be tested that enters the second placement seat 32, so as to avoid the shaking of the packaging bowl 2 to be tested as much as possible, thereby ensuring the subsequent fixing and adsorption effect.
[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
