Description

TECHNICAL FIELD

[0002] Bottle cap is important in food and drink packaging, and it is also the first place for consumers to contact the product. Bottle caps have the ability to keep the contents of the product sealed. Depending on the function, there are bottle caps of different shapes and different operating methods. Some of these bottle caps also have anti-theft features. These bottle caps typically include a cap body and an anti-theft ring. The anti-theft ring is connected to the cap body by a connecting bridge. When the bottle cap is opened, the connecting bridge breaks away from the container along with the cap body, thereby providing an anti-theft effect.

[0003] The strength of the bottle cap connecting bridge is an important indicator of the opening performance of the plastic anti-theft bottle cap. Therefore, during the production of bottle caps, the strength of the bottle cap connecting bridge needs to be tested. Currently, the testing device typically clamps the anti-theft ring on a limiting jig, then pushes the cap body using a telescopic assembly (such as an electric cylinder or a pneumatic cylinder), causing the cap body to separate from the anti-theft ring. The force required to break the bottle cap connecting bridge between the anti-theft ring and the cap body is tested by a pressure sensor, thereby achieving strength testing of the bottle cap connecting bridge. However, after the test is completed, the anti-theft ring is still clamped on the limiting jig, and needs to be manually removed, which is time-consuming and labor-intensive. SUMMARY

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0040] Please refer to Figures 1 to 3 The utility model discloses an online strength detection device of bottle lid connecting bridge, including: support 10, limit fixture 20, test mechanism 30 and material return mechanism 40.

[0041] The limit fixture 20 is arranged on the support 10, and the limit fixture 20 has a limiting portion 21 for limiting cooperation with the anti-theft ring 61 of the bottle cap.

[0042] The testing mechanism 30 comprises a testing driving assembly 31 and a movable piece 32. The testing driving assembly 31 is arranged on the support 10 and is drivingly connected with the movable piece 32. The movable piece 32 is configured to drive the cover body 62 of the bottle cap away from the limiting portion 21 under the driving of the testing driving assembly 31. During testing, the anti-theft ring 61 of the bottle cap is in limiting fit with the limiting portion 21. Then, the testing driving assembly 31 drives the movable piece 32 to move. The movable piece 32 pushes the cover body 62 of the bottle cap to move away from the limiting portion 21. Thus, the connecting bridge between the anti-theft ring 61 and the cover body 62 is gradually stretched until being torn off. Subsequently, the anti-theft ring 61 and the cover body 62 are separated from each other. When the connecting bridge is torn off, the force applied by the testing driving assembly 31 reaches the maximum. The strength of the connecting bridge is determined by detecting the maximum force.

[0043] The testing driving assembly 31 is a translation driving assembly with a pressure testing module. The specific structure of the testing driving assembly 31 can be selected according to actual needs. For example, the testing driving assembly 31 comprises a pressure tester and a cylinder.

The cutting tool 42 is movably arranged on one side of the limiting jig 20 and is configured to move close to or away from the limiting portion 21 under the driving of the cutting driving assembly 41. After testing is completed, the cover body 62 is separated from the anti-theft ring 61 and falls off. The anti-theft ring 61 is still retained on the limiting portion 21 due to the limiting fit with the limiting portion 21. The cutting driving assembly 41 drives the cutting tool 42 to move towards the limiting portion 21. Thus, the cutting tool 42 cuts the anti-theft ring 61. The anti-theft ring 61 is cut and separated. Thus, the anti-theft ring 61 is quickly separated from the limiting portion 21. The anti-theft ring 61 can fall off under the action of its own gravity. Thus, the next testing is facilitated.

[0045] The specific structure of the cutting driving assembly 41 can be selected according to actual needs. For example, the cutting driving assembly 41 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder.

[0046] In some optional embodiments, the rack 10 is provided with a discharge cover 11, the discharge cover 11 surrounds a discharge space 111, the discharge space 111 is provided with a gas source inlet 112 and a discharge port, at least part of the limiting part 21 is located in the discharge space 111, facilitating the cover 62 and the anti-theft ring 61 on the limiting part 21 to fall into the discharge space 111. The gas source inlet 112 is connected with a gas blowing source, the gas source inflates the discharge space 111 in the discharge cover 11, so that the cover 62 and the anti-theft ring 61 falling from the limiting part 21 are blown to the discharge port by the gas, facilitating the discharge. Preferably, the gas source inlet 112 and the discharge port are distributed on both sides of the discharge space 111, facilitating the gas to blow the waste to the discharge port.

[0047] In some optional embodiments, the on-line strength detection device of the bottle cap connecting bridge further comprises a feeding mechanism 50; the feeding mechanism 50 comprises a cap pushing driving assembly 51 and a cap pushing piece 52, the cap pushing driving assembly 51 is arranged on the rack 10 and is drivingly connected with the cap pushing piece 52, the cap pushing piece 52 is configured to approach or move away from the limiting part 21 under the driving of the cap pushing driving assembly 51. The bottle cap is arranged between the cap pushing piece 52 and the limiting part 21, the cap pushing piece 52 drives the bottle cap to move towards the limiting part 21 under the driving of the cap pushing driving assembly 51, so that the anti-theft ring 61 is limitedly matched with the limiting part 21, facilitating the automatic feeding.

[0048] The specific structure of the cap pushing driving assembly 51 can be selected according to actual needs, for example, the cutting driving assembly 41 can adopt an electric cylinder, a gas cylinder or a hydraulic cylinder.

[0050] The feeding mechanism 50 further comprises a power assembly 53, which is drivingly connected with the movable cover body 114. The movable cover body 114 is movable relative to the fixed cover body 113 to the avoiding position and the closed position under the driving of the feeding mechanism 50. When the movable cover body 114 is in the closed position relative to the fixed cover body 113, the fixed cover body 113 and the movable cover body 114 cooperatively form the discharging space 111. The limiting part 21 and the push cover 52 are both arranged between the fixed cover body 113 and the movable cover body 114. When the discharging cover 11 and the feeding mechanism 50 are arranged simultaneously, the movable cover body 114 is moved to the avoiding position to avoid the movement of the push cover 52. When the anti-theft ring 61 needs to be limited and matched with the limiting part 21, the movable cover body 114 is moved to the avoiding position, the push cover 52 is moved under the driving of the push cover driving assembly 51, and after the anti-theft ring 61 is limited and matched with the limiting part 21, the movable cover body 114 is moved back to the closed position, thereby forming the discharging space 111.

[0051] In some optional embodiments, the bracket 10 is provided with a feeding channel 12; the feeding mechanism 50 further comprises a rotating disc 54, which is rotationally arranged on the bracket 10 and located between the feeding channel 12 and the push cover 52. The rotating disc 54 is provided with a positioning groove 55 for positioning and matching with the bottle cap. The power assembly 53 is drivingly connected with the rotating disc 54. The rotating disc 54 is rotated under the driving of the power assembly 53 to move the positioning groove 55 between the feeding channel 12 and the push cover 52. In order to facilitate the automatic conveying of the bottle cap between the push cover 52 and the limiting part 21, the bottle cap enters the feeding channel 12 and then enters the positioning groove 55. Then the rotating disc 54 is rotated to move the positioning groove 55 to the push cover 52, so that the bottle cap is moved to the push cover 52 and the limiting part 21. Then the push cover 52 pushes the bottle cap to the limiting part 21, so that the anti-theft ring 61 of the bottle cap is limited and matched with the limiting part 21.

[0052] The feeding channel 12 can be connected to the discharging channel of the bottle cap production system. The bottle cap in the discharging channel is blown into the feeding channel 12 at a certain time interval by the blowing mechanism, and the bottle cap is moved into the positioning groove 55, so as to realize online continuous monitoring and improve the bottle cap quality monitoring effect.

[0053] In order to facilitate the movement of the movable cover body 114, in some optional embodiments, the movable cover body 114 is arranged on the rotating disc 54. When the movable cover body 114 is in the avoiding position, the positioning groove 55 is located at the push cover 52. When the movable cover body 114 is in the closed position, the positioning groove 55 is located at the feeding channel 12. The power assembly 53 can drive the movement of the rotating disc 54 and the movable cover body 114, which is beneficial to simplify the overall structure and enable a single power assembly 53 to realize the movement of the movable cover body 114 and the conveying of the bottle cap.

[0054] When the discharge cover 11 is not provided, the power assembly 53 is drivingly connected with the rotating disc 54, and when the rotating disc 54 is not provided, the power assembly 53 is directly drivingly connected with the movable cover body 114.

[0055] The specific structure of the power assembly 53 can be selected according to actual needs, for example, the power assembly 53 adopts a driving motor, in the embodiment, the driving motor is drivingly connected with the rotating disc 54 to drive the rotating disc 54 and the movable cover body 114 to move synchronously. When the rotating disc 54 is not provided, the power assembly 53 can also adopt other suitable power assemblies 53, for example, the power assembly 53 can adopt an electric cylinder, a hydraulic cylinder or a pneumatic cylinder.

[0056] In some optional embodiments, the material returning mechanism 40 further comprises a material returning driving assembly 43 and an auxiliary material returning piece 44, the material returning driving assembly 43 is drivingly connected with the auxiliary material returning piece 44, the auxiliary material returning piece 44 is arranged on one side of the limiting jig 20, and the auxiliary material returning piece 44 is configured to move close to or away from the limiting portion 21 under the driving of the material returning driving assembly 43. After the cutting tool 42 cuts off the anti-theft ring 61, in order to ensure that the anti-theft ring 61 can accurately and stably separate from the limiting portion 21, the material returning driving assembly 43 drives the auxiliary material returning piece 44 to move, the auxiliary material returning piece 44 pushes the anti-theft ring 61 on the limiting portion 21 to separate from the limiting portion 21, and the anti-theft ring 61 stably separates from the limiting portion 21.

[0057] The specific structure of the material returning driving assembly 43 can be selected according to actual needs, for example, the material returning driving assembly 43 can adopt an electric cylinder, a hydraulic cylinder or a pneumatic cylinder.

[0058] Please refer to Figure 6 In some optional embodiments, the limiting portion 21 is provided with a limiting buckle portion 22 arranged around the limiting portion 21, the limiting buckle portion 22 stably buckles with the anti-theft ring 61, so that the anti-theft ring 61 can be stably limited on the limiting portion 21, and the stress stability of the anti-theft ring 61 is improved.
