Description

Technical Field

[0001] This utility model relates to the field of coffee product testing, and in particular to a coffee capsule sealing testing device. Background Technology

[0002] Coffee capsules are made by encapsulating freshly ground coffee powder into sealed capsules filled with inert gas, thus extending the shelf life and flavor period of the coffee. Therefore, coffee capsules need to have excellent sealing performance. In related technologies, coffee capsules are sealed to the can using a hot-pressing process, where an aluminum-plastic film is pressed into the capsule. This hot-pressing process is carried out using automated hot-pressing equipment. Over long-term use, this automated hot-pressing equipment experiences mechanical wear, leading to a decrease in manufacturing precision. Furthermore, each time the automated hot-pressing equipment stops operating, some errors occur in the break-in of its parts, causing fluctuations in manufacturing precision when the equipment restarts. Therefore, after producing a predetermined number of coffee capsules or after the equipment has been shut down, the sealing performance of the coffee capsules must be tested. Production can only continue after the sealing performance of the coffee capsules meets the standards. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a coffee capsule sealing detection device, capable of detecting the sealing performance of coffee capsules and improving the production quality of coffee capsules.

[0004] The coffee capsule sealing detection device according to an embodiment of the present invention includes:

[0005] The testing chamber contains a testing solution;

[0006] A magnetic assembly includes a first magnetic component and a second magnetic component that can be magnetically connected. The first magnetic component is used to be placed inside a coffee capsule, and the second magnetic component is used to magnetically hold the sealing film of the coffee capsule with the first magnetic component.

[0007] A fixing component includes a first fixing member, a second fixing member, and a tension driving source. The tension driving source is driveably connected to at least one of the first fixing member and the second fixing member. The first fixing member is used to fix the canister of the coffee capsule, and the second fixing member is used to fix the second magnetic member. The tension driving source is capable of driving the first fixing member and the second fixing member to move away from each other.

[0008] The detection component includes a bubble detector and a tensile force detector. The bubble detector is used to detect bubbles generated between the sealing membrane and the can in the detection solution. The tensile force detector is disposed in the force transmission path of the tensile force driving source to detect the tensile force applied by the tensile force driving source.

[0009] The coffee capsule sealing detection device according to an embodiment of the present invention has at least the following beneficial effects: Before sealing the coffee capsule can, a first magnetic component is placed inside the can, and then a sealing film is sealed to the can, so that the first magnetic component is sealed inside the coffee capsule. Then, the first magnetic component inside the coffee capsule is magnetically connected to a second magnetic component outside the coffee capsule. The first and second magnetic components will hold the sealing film, and the sealing area between the sealing film and the can is located within the detection solution. Then, a first fixing component fixes the can, a second fixing component fixes the second magnetic component, and a tension driving source applies a preset tension to the first fixing component. The force and tension detection device displays the tension value applied by the tension drive source in real time. When the tension detection device detects that the tension applied by the tension drive source reaches a preset value, the tension drive source maintains that tension. If no air bubbles are generated in the sealing area between the sealing film and the can, the coffee capsule's sealing performance meets the design requirements. If air bubbles are generated in the sealing area between the sealing film and the can, the air bubble detection device will detect the air bubbles, and the coffee capsule's sealing performance does not meet the design requirements. The hot pressing equipment for the sealing can and sealing film needs to be adjusted. After adjustment, the above process is repeated until no air bubbles are generated in the sealing area between the sealing film and the can. Ultimately, this achieves the sealing performance detection of coffee capsules and improves the sealing quality of coffee capsules produced by the hot pressing equipment, thereby improving product quality.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] Reference Figures 1 to 6As shown in the figure, this utility model embodiment proposes a coffee capsule sealing detection device, including: a detection box 100, a magnetic suction assembly 200, a fixing assembly 300, and a detection assembly 400. The detection box 100 has a detection solution 110. The magnetic suction assembly 200 includes a first magnetic element 210 and a second magnetic element 220 that can be magnetically connected. The first magnetic element 210 is used to be placed inside the coffee capsule 10, and the second magnetic element 220 is used to magnetically clamp the sealing film 11 of the coffee capsule 10 with the first magnetic element 210. The fixing assembly 300 includes a first fixing element 310, a second fixing element 320, and a tension driving source 330, which drives the transmission. The first fixing member 310 and the second fixing member 320 are connected to at least one of them. The first fixing member 310 is used to fix the canister 12 of the coffee capsule 10, and the second fixing member 320 is used to fix the second magnetic member 220. The tension driving source 330 can drive the first fixing member 310 and the second fixing member 320 away from each other. The detection assembly 400 includes a bubble detection member 410 and a tension detection member 420. The bubble detection member 410 is used to detect bubbles generated between the sealing film 11 and the canister 12 in the detection solution 110. The tension detection member 420 is disposed in the force transmission path of the tension driving source 330 to detect the tension applied by the tension driving source 330.

[0038] It should be noted that when testing the sealing performance of the coffee capsule 10, the sealing area between the canister 12 and the sealing membrane 11 needs to be below the surface of the test solution 110. When leakage occurs in the sealing area between the canister 12 and the sealing membrane 11, bubbles will be generated in the test solution 110. The bubble detection element 410 can detect these bubbles, thereby determining the sealing performance of the coffee capsule 10. Specifically, the magnetic suction component 200 clamps the sealing membrane 11, the fixing component 300 fixes the canister 12, and the magnetic component fixes the sealing membrane 11. The fixing component 300 controls the canister 12 and the sealing membrane 11 to move away from each other, so that the sealing area between the sealing membrane 11 and the canister 12 is subjected to a preset tension.

[0039] In this embodiment, the top of the detection box 100 has an opening, and the detection box 100 is used to hold the detection solution 110. The side of the detection box 100 has an observation window, through which the sealing area between the sealing membrane 11 and the container 12 in the detection solution 110 can be observed. The bubble detection device 410 can detect bubbles smoothly through the observation window. Specifically, the detection box 100 is transparent in its entirety or partially on its side, and this transparent part forms the observation window. The detection solution 110 is also a transparent solution. The bubble detection device 410 includes a visual bubble detector, and the bubble detection device 410 can directly detect the sealing area between the container 12 and the sealing membrane 11 through the observation window.

[0040] The magnetic assembly 200 includes a first magnetic element 210 and a second magnetic element 220 that can be magnetically connected. The first magnetic element 210 is placed inside the can 12 before the can body 12 is sealed to the sealing film 11. The can 12 is sealed to the sealing film 11 with the first magnetic element 210 in place, so that the first magnetic element 210 is sealed inside the coffee capsule 10. The second magnetic element 220 is located outside the coffee capsule 10. When the second magnetic element 220 and the first magnetic element 210 are magnetically attracted to each other through the sealing film 11, because the sealing film 11 is relatively thin, the sealing film 11 will not significantly affect the magnetic attraction between the first magnetic element 210 and the second magnetic element 220. The first magnetic element 210 and the second magnetic element 220 can still maintain a certain magnetic attraction, thereby enabling the magnetic assembly 200 to clamp and fix the sealing film 11.

[0041] The fixing assembly 300 includes a first fixing member 310, a second fixing member 320, and a tension driving source 330. The first fixing member 310 is used to fix the canister 12 of the coffee capsule 10. Specifically, the first fixing member 310 can fix the canister 12 by clamping, vacuum adsorption, or other methods. The fixing position of the first fixing member 310 can be located on the outer peripheral surface or the bottom surface of the canister 12. For example, the first fixing member 310 clamps the outer peripheral surface of the canister 12, or the first fixing member 310 vacuum adsorbs the bottom surface of the canister 12. The second fixing member 320 is used to fix the second magnetic member 220. Specifically, the second fixing member 320 can be connected to the second magnetic member 220 as a whole, or the second magnetic member 220 can be fixed by clamping, vacuum adsorption, or other methods. The tension drive source 330 is connected to the first fixing member 310 and can pull the first fixing member 310 apart from the second fixing member 320, thereby generating a tearing force between the can 12 and the sealing film 11. When the tension drive source 330 applies a preset tension, the designed sealing force between the can 12 and the sealing film 11 should be greater than the tearing force, so that the can 12 and the sealing film 11 remain sealed and no air bubbles are generated between the can 12 and the sealing film 11. At this time, the sealing performance of the coffee capsule 10 meets the standard, and the parameters of the hot pressing equipment do not need to be adjusted, and production can proceed normally. Conversely, if air bubbles are generated between the can 12 and the sealing film 11 when the tension drive source 330 applies the preset tension, the sealing performance of the coffee capsule 10 does not meet the standard, and the parameters of the hot pressing equipment need to be adjusted. After the parameters are adjusted, the hot pressing equipment produces new coffee capsules 10 for sealing performance testing. Production can only continue until the sealing performance of the produced coffee capsules 10 passes the test. The bubble detector 410 is connected to a control terminal, which in turn is connected to the hot-pressing equipment. When the bubble detector 410 detects bubbles in the sealing area between the tank 12 and the sealing film 11, it sends a signal to the control terminal. The control terminal then automatically adjusts the parameters of the hot-pressing equipment according to preset conditions. These adjustment parameters include, but are not limited to, hot-pressing pressure, hot-pressing time, and hot-pressing temperature. Furthermore, a tension detector 420 is located in the force transmission path of the tension drive source 330 to detect the tension applied by the tension drive source 330. This allows the detector to determine whether the applied tension meets the preset tension value, facilitating adjustment of the tension value of the tension detector 420.

[0042] It is understandable that before sealing the canister 12 of the coffee capsule 10, the first magnetic component 210 is placed inside the canister 12, and then the sealing film 11 is sealed to the canister 12, so that the first magnetic component 210 is sealed inside the coffee capsule 10. Then, the first magnetic component 210 inside the coffee capsule 10 is magnetically connected to the second magnetic component 220 outside the coffee capsule 10. The first magnetic component 210 and the second magnetic component 220 will hold the sealing film 11, and the sealed area between the sealing film 11 and the canister 12 is located within the detection solution 110. Then, the first fixing component 310 fixes the canister 12, the second fixing component 320 fixes the second magnetic component 220, and the tension drive source 330 applies a preset tension to the first fixing component 310. The tension detection element 420 displays the tension value applied by the tension drive source 330 in real time. When the tension detection element 420 detects that the tension applied by the tension drive source 330 reaches a preset value, the tension drive source 330 maintains that tension. If no air bubbles are generated in the sealing area between the sealing membrane 11 and the can 12, the sealing performance of the coffee capsule 10 meets the design requirements. If air bubbles are generated in the sealing area between the sealing membrane 11 and the can 12, the air bubble detection element 410 will detect the air bubbles, and the sealing performance of the coffee capsule 10 does not meet the design requirements. The hot pressing equipment between the sealing can 12 and the sealing membrane 11 needs to be adjusted. After adjustment, the above process is repeated until no air bubbles are generated in the sealing area between the sealing membrane 11 and the can 12. Ultimately, the sealing performance of the coffee capsule 10 is detected, and the sealing quality of the coffee capsules 10 produced by the hot pressing equipment is improved, thereby improving product quality.

[0043] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, at least one of the first magnetic element 210 and the second magnetic element 220 includes a magnet, and the other can be magnetically attracted by the magnet.

[0044] Specifically, the first magnetic component 210 includes iron, and the second magnetic component 220 includes a magnet, which can magnetically attract the iron; alternatively, the first magnetic component 210 includes a magnet, and the second magnetic component 220 includes iron, thereby achieving magnetic attraction; furthermore, both the first magnetic component 210 and the second magnetic component 220 include magnets, with opposite poles attracting each other. It is worth noting that when the first magnetic component 210 includes iron, it is less likely to cause magnetic interference to the hot-pressing equipment during the production process of the can 12, which can greatly replicate the actual production process of the coffee capsule 10, reduce variables, and make the sealing performance testing of the coffee capsule 10 more accurate. In this embodiment, the magnet can be an electromagnet or a permanent magnet.

[0045] Reference Figure 2 As shown, in some specific embodiments of this utility model, the first fixing member 310 and the second fixing member 320 are arranged opposite each other in the horizontal or vertical direction.

[0046] In this embodiment, when the first fixing member 310 and the second fixing member 320 are arranged opposite each other in the horizontal direction, the first fixing member 310 and the second fixing member 320 will separate the can 12 and the sealing film 11 in the horizontal direction, and the coffee capsule 10 will be placed horizontally. When the first fixing member 310 and the second fixing member 320 are arranged opposite each other in the vertical direction, the first fixing member 310 and the second fixing member 320 will separate the can 12 and the sealing film 11 in the vertical direction, and the coffee capsule 10 will be placed vertically or upside down. Here, the horizontal direction is a direction that is substantially parallel to the ground, and the vertical direction is a direction that is substantially perpendicular to the ground.

[0047] Reference Figure 4 As shown, in some specific embodiments of this utility model, the radial dimension of the first magnetic element 210 is L1, and the inner diameter of the tank 12 is L2, wherein the first magnetic element 210 satisfies: L1≤L2.

[0048] It should be noted that the inner diameter of the tank 12 refers to the radial dimension of the internal cavity of the tank 12. The radial dimension of the first magnetic component 210 refers to the radial dimension of the overall outline of the first magnetic component 210.

[0049] In this embodiment, the outer periphery of the first magnetic component 210 is circular, and the inner periphery of the can 12 is conical. The inner diameter of the can 12 refers to its maximum inner diameter. The radial dimension of the first magnetic component 210 is equal to or slightly smaller than the inner diameter of the can 12. This ensures that the first magnetic component 210 is engaged at the opening of the can 12 without penetrating to the bottom. Furthermore, the first magnetic component 210 is less prone to flipping within the can 12, maintaining its orientation and facilitating maximum contact between the first magnetic component 210 and the sealing film 11. This also makes the magnetic adsorption between the first magnetic component 210 and the second magnetic component 220 more reliable. Furthermore, the inner circumferential surface of the can 12 can also be a square pyramid or other pyramidal shape. The shape of the outer circumference of the first magnetic element 210 matches the shape of the inner circumference of the can 12, so that the first magnetic element 210 can be precisely engaged within the can 12 and is not easily flipped or shaken within the can 12. In addition, the outer circumference of the first magnetic element 210 is circular. The first magnetic element 210 can be disc-shaped or ring-shaped. When the first magnetic element 210 is ring-shaped, it has a through hole. The shape of the through hole can be circular, square, or other shapes, that is, the shape of the through hole can be consistent with or inconsistent with the shape of the outer circumference of the first magnetic element 210.

[0050] In some specific embodiments of this utility model, the first magnetic component 210 includes a first magnet and a first anti-rust layer, with the first anti-rust layer covering the outer surface of the first magnet. It is understood that by protecting the first magnet with the first anti-rust layer, the first magnetic component 210 exhibits better anti-rust performance, effectively preventing the possibility of the first magnetic component 210 being corroded by the detection solution 110.

[0051] In another embodiment, the second magnetic component 220 includes a second magnet and a second anti-rust layer, the second anti-rust layer covering the outer surface of the second magnet. It is understood that by protecting the second magnet with the second anti-rust layer, the second magnetic component 220 exhibits better anti-rust performance, effectively preventing the possibility of the second magnetic component 220 being corroded by the detection solution 110.

[0052] Reference Figure 2 As shown, in some specific embodiments of this utility model, one of the first fixing member 310 and the second fixing member 320 is fixedly disposed inside the detection box 100 and located inside the detection solution 110.

[0053] In this embodiment, the second fixing member 320 is fixedly disposed at the bottom of the detection box 100, and the highest point of the second fixing member 320 is fixed with the second magnetic member 220. When the highest point of the second fixing member 320 is below the liquid surface of the detection solution 110, the second magnetic member 220 will also be below the liquid surface of the detection solution 110. This allows the first magnetic member 210 and the second magnetic member 220 in the coffee capsule 10 to be magnetically attracted, so that the sealing area between the sealing film 11 and the can body 12 can be below the liquid surface of the detection solution 110, thereby facilitating the observation of bubbles generated in the sealing area. Alternatively, the second fixing member 320 can also be fixed to the inner side of the detection box 100.

[0054] In another embodiment, the first fixing member 310 is fixed inside the detection box 100, and the opening of the tank 12 fixed by the first fixing member 310 can be immersed in the detection solution 110.

[0055] Reference Figure 2 As shown, in some specific embodiments of this utility model, the first fixing member 310 includes a first clamping part 311, a second clamping part 312 and a clamping drive source 313. The clamping drive source 313 is tractively connected to the first clamping part 311 and the second clamping part 312. The first clamping part 311 and the second clamping part 312 are opposite to each other and spaced apart. A clamping cavity for clamping the can body 12 is formed between the first clamping part 311 and the second clamping part 312.

[0056] In this embodiment, the clamping drive source 313 can drive the first clamping part 311 and the second clamping part 312 to move towards each other and reduce the clamping cavity. The first clamping part 311 and the second clamping part 312 clamp the can 12 located in the clamping cavity, thereby clamping and fixing the can 12. The clamping drive source 313 can be pneumatically driven or electrically controlled.

[0057] Furthermore, the tension drive source 330 includes a winding motor, a winding reel, and a winding rope. The winding reel is drivenly connected to the winding motor. One end of the winding rope is connected to the winding reel, and the other end is connected to one end of the tension detection element 420. The other end of the tension detection element 420 is connected to the first fixing element 310. The rotation of the winding motor drives the winding reel to rotate, thereby applying tension to the tension detection element 420 and the first fixing element 310 through the winding rope, causing the first fixing element 310 to move away from the second fixing element 320. The winding motor can be fixed to a location such as a roof. Alternatively, the fixing assembly 300 also includes a stand with pulleys. The winding motor is mounted on the ground or a platform, and the winding rope is slidably connected to the pulleys. The pulleys change the direction of the applied force, allowing the winding rope to drive the first fixing element 310 away from the second fixing element 320.

[0058] In some specific embodiments of this utility model, the first clamping part 311 includes a first clamping surface for clamping the can body 12 and a first friction layer disposed on the first clamping surface. It is worth understanding that the first friction layer can increase the frictional force, so that the frictional force when the first friction layer contacts the outer peripheral surface of the can body 12 is greater, thereby improving the clamping reliability.

[0059] In this embodiment, the second clamping part 312 includes a second clamping surface for clamping the can 12 and a second friction layer disposed on the second clamping surface. The second friction layer can increase the frictional force, making the frictional force when the second friction layer contacts the outer peripheral surface of the can 12 greater, thereby improving the clamping reliability.

[0060] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the second magnetic component 220 and the second fixing component 320 are connected as an integral structure, eliminating the need for assembly during use and making it more convenient. In this embodiment, the second fixing component 320 is directly fixed to the bottom of the detection box 100, keeping the second magnetic component 220 fixed. When separating the tank 12 from the sealing membrane 11, the tank 12 is mainly moved by the first fixing component 310, thereby separating the tank 12 from the sealing membrane 11. The overall structure of the device requires less power, resulting in a simpler structure and lower cost.

[0061] In some specific embodiments of this utility model, the inner circumferential surface of the detection box 100 has a hydrophilic layer.

[0062] It is understandable that the hydrophilic layer increases the contact area between water and the inner circumferential surface of the detection chamber 100, preventing air from remaining on the inner circumferential surface of the detection chamber 100 and forming bubbles. During the water inlet process of the detection chamber 100, bubbles are less likely to remain on the inner circumferential surface of the detection chamber 100, effectively reducing and avoiding interference from excess bubbles, thereby improving the detection accuracy of the bubble detection component 410.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
