When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0046] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0047] The structure of the existing can sealing machine refers to the structure described in the patent application number CN201510402409.0 and the name is full-automatic PET plastic can vacuum nitrogen filling can sealing machine.

[0048] The can sealing machine includes a vacuum chamber 400 (sealing cylinder), and two sealing wheels are arranged in the vacuum chamber 400. The sealing wheels are driven by corresponding wheel cylinders. For this purpose, the wheel cylinders need to be sealed and connected to the side walls of the vacuum chamber 400 to ensure that the sealing wheels perform capping operations under a vacuum environment. A capping motor (rotating motor) is also provided in the vacuum chamber 400 to drive the cans and cans to rotate synchronously. For this purpose, the capping motor also needs to be sealed and connected to the vacuum chamber 400. Similarly, in order to facilitate the cans and cans to be packaged to enter the vacuum chamber 400, a cover delivery tray (easy-pull cover tray) is provided below the vacuum chamber 400. The cover delivery tray slides back and forth in the horizontal direction to move the received cover to the bottom of the vacuum chamber 400, and the bottom tray 500 below the vacuum chamber 400 moves up and seals the lower side of the cover delivery tray, and the upper side of the cover delivery tray is sealed with the vacuum chamber 400 to form a sealed space, and then the capping operation is performed in the sealed space. The specific steps can refer to the contents recorded in the prior art.

[0049] It is not difficult to see that the vacuum chamber 400 is connected to multiple mechanisms, some of which involve pneumatic drive. Therefore, if there is a leakage problem in the entire canning machine, the corresponding leakage points may be the vacuum chamber 400 (including the air pipe pipeline of the vacuum chamber 400, etc.), the connection point between the vacuum chamber 400 and the wheel cylinder (including the air pipe pipeline connected to the wheel cylinder), the connection point between the vacuum chamber 400 and the capping motor (including the various connection points of the capping motor), and the connection point between the vacuum chamber 400 and the capping tray.

[0050] In the prior art, when a can sealing machine leaks, the only way is to manually inspect each mechanism and find the leak point by manual observation, listening and feeling. However, there are many ventilation nodes in the can sealing machine, and a comprehensive inspection usually takes more than 40 minutes, which seriously affects production efficiency. Moreover, when there are multiple leak points, manual inspection may miss the leak.

[0051] To solve the above problems, the inventor provides a detection tool, which is used in conjunction with the vacuum chamber 400 to quickly find the leakage point on the vacuum chamber 400 or the leakage mechanism connected to the vacuum chamber 400, and then conduct troubleshooting on the leakage mechanism to reduce the troubleshooting time of the leakage point of the entire can sealing machine and improve the efficiency and accuracy of the can sealing detection of the can sealing machine.

[0052] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0053] Reference Figure 1-3 As shown, a detection tool for the sealing performance of a can seaming machine includes a capping motor detection component 100, a cap feeding tray detection component 300 and at least one wheel detection component 200. The capping motor detection component 100 has a first connecting portion 110, and the first connecting portion 110 is used to fit the first interface portion 410 of the vacuum chamber 400 of the can seaming machine and close the first interface portion 410; the wheel detection component 200 has a second connecting portion 210, and the second connecting portion 210 is used to fit the second interface portion 420 of the vacuum chamber 400 and close the second interface portion 420; the cap feeding tray detection component 300 has a third connecting portion 340, and the third connecting portion 340 is used to fit the third interface portion 430 of the vacuum chamber 400 and close the third interface portion 430 together with the bottom tray 500 of the can seaming machine.

[0054] It can be understood that the first interface part 410 on the vacuum chamber 400 is sealed and connected to the capping motor; in order to detect whether the connection point, or other parts connected to the capping motor are leaking, it is only necessary to remove the capping motor, use the capping motor detection part 100 to seal the vacuum chamber 400, evacuate or inflate the vacuum chamber 400, and observe the change in air pressure to determine whether the connection point or other parts of the capping motor are leaking.

[0055] To this end, the function of the capping motor detection member 100 is to ensure that it can replace the capping motor and be sealed and connected to the vacuum chamber 400. Therefore, the capping motor detection member 100 of the present application can adopt a plate-shaped structure, a block-shaped structure or any other external structure, and it only needs to ensure that the structure of the first connecting portion 110 is compatible with the first interface portion 410 of the vacuum chamber 400.

[0056] Similarly, the second interface 420 provided on the vacuum chamber 400 is sealedly connected to the wheel cylinder of the can sealing machine, and two wheel cylinders are usually provided, so at least one wheel detection member 200 is provided. To detect whether the connection point between the wheel cylinder and the vacuum chamber 400 or the air pipe connected to the wheel cylinder is leaking, it is only necessary to disassemble the wheel cylinder and the vacuum chamber 400, and cover the second interface 420 with the wheel detection member 200, and seal it with the vacuum chamber 400. Then, the vacuum chamber 400 is evacuated or inflated, and the air pressure change is observed to determine whether the connection point or the air pipe connected to the wheel cylinder is leaking.

[0057] Therefore, the wheel detection member 200 is used to achieve a sealed connection with the vacuum chamber 400. Therefore, the structure of the wheel detection member 200 in the present application can be a plate structure, a block structure or any other external structure, as long as the structure of the second connection portion 210 is adapted to the second interface portion 420 of the vacuum chamber 400.

[0058] Correspondingly, the cover delivery tray detection member 300 is used to detect the airtightness of the connection point between the vacuum chamber 400 and the cover delivery tray. For this purpose, the cover delivery tray detection member 300 is used to replace the cover delivery tray to ensure that the upper and lower sides of the cover delivery tray detection member 300 can be sealed with the vacuum chamber 400 and the bottom tray 500 respectively. Therefore, the cover delivery tray detection member 300 can be set in any shape such as a plate structure, a rectangular block structure, a cylindrical structure, etc., and it is only necessary to ensure that the third connection part 340 can be sealed and connected with the third interface part 430.

[0059] The detection principle of this application is as follows:

[0060] Step 1: Vacuum chamber 400 airtightness test

[0061] The capping motor, wheel cylinder, and cap feeding tray connected to the vacuum chamber 400 are replaced with the capping motor detection component 100 , the wheel detection component 200 , and the cap feeding tray detection component 300 , respectively.

[0062] The vacuum chamber 400 is pressurized with 0.2 MPa compressed air, and the pressure is maintained for less than 5 seconds, and it is determined that the vacuum chamber 400 is leaking.

[0063] Step 2: Sealing test of the connection point between the capping motor and the vacuum chamber 400

[0064] On the basis of step 1, the vacuum chamber 400 is pressurized for more than 5 seconds, and the capping motor detection component 100 is replaced with the capping motor; the vacuum chamber 400 is pressurized with 0.2 MPa compressed air, and the pressure is maintained within 5 seconds to determine whether the capping motor seal is leaking.

[0065] Step 3: Check the sealing of the connection point between the wheel cylinder and the vacuum chamber 400

[0066] On the basis of step 1 or step 2, if the vacuum chamber 400 is pressurized for more than 5 seconds, replace the wheel detection component 200 with a wheel cylinder; continue to pressurize the vacuum chamber 400 with 0.2 MPa compressed air, and the pressure holding time is within 5 seconds, which is judged as a wheel seal leakage.

[0067] Step 4: Check the sealing of the connection point between the cover tray and the vacuum chamber 400

[0068] On the basis of step 1 or step 2 or step 3, if the vacuum chamber 400 is pressurized for more than 5 seconds, replace the cover delivery tray detection component 300 with the cover delivery tray; continue to pressurize the vacuum chamber 400 with 0.2MPa compressed air, and the pressure maintenance time is within 5 seconds, it is determined that the cover delivery tray seal is leaking.

[0069] Through the detection tooling of the present application, the leaking points or leaking mechanisms of the can sealing machine can be quickly detected, and then the leaking mechanisms can be detected. The method of using the detection tooling to perform airtightness detection on the can sealing machine can reduce the time by more than half compared with manual detection, thereby improving detection efficiency and accuracy.

[0070] In a possible implementation, the first connection portion 110 has an annular first recessed groove 111 , and the first recessed groove 111 is used to embed the first sealing ring 600 , and the first sealing ring 600 is attached to the first interface portion 410 .

[0071] It can be understood that the first sealing ring 600 is used to achieve a sealed connection between the capping motor detection member 100 and the vacuum chamber 400. For this purpose, the present application is provided with a first recessed groove 111 that facilitates the positioning of the first sealing ring 600. The first recessed groove 111 is in a circular ring shape, a rectangular ring shape, etc., to ensure that the corresponding first sealing ring 600 can be embedded.

[0072] Reference Figure 1 , 5 As shown, the capping motor detection component 100 is a plate-like structure, the first connecting portion 110 is located on one side of the capping motor detection component 100, the first recessed groove 111 is annular, the first sealing ring 600 is a circular ring structure, the first sealing ring 600 is embedded in the first recessed groove 111, and part of the first sealing ring 600 is located outside the first recessed groove 111, then when the capping motor detection component 100 and the first interface portion 410 are closed, the first sealing ring 600 can contact the outer wall of the vacuum chamber 400 to achieve sealing.

[0073] In a possible implementation, the first connection portion 110 has an annular raised ring 112 , which is located inside the annular first recessed groove 111 and adjacent to the first recessed groove 111 , and extends in a direction away from the first recessed groove 111 .

[0074] It can be understood that the first interface portion 410 is a through-hole structure opened on the vacuum chamber 400 . Based on the structure of the first interface portion 410 , the raised ring 112 can play a positioning role so that the first sealing ring 600 can cover the first interface portion 410 .

[0075] Reference Figure 1 , 5 As shown, the structure of the raised ring 112 of the present application is adapted to the annular structure of the first recessed groove 111 , and the raised ring 112 is located on the inner side of the first recessed groove 111 and is adjacent to the first recessed groove 111 .

[0076] When the capping motor detection component 100 and the vacuum chamber 400 are installed, the raised ring 112 is embedded in the first interface portion 410 to guide the capping motor detection component 100, ensuring that the first sealing ring 600 is in contact with the end side wall of the first interface portion 410 (the outer wall of the vacuum chamber 400) or the first sealing ring 600 covers the first interface portion 410. After the capping motor detection component 100 and the vacuum chamber 400 are fixed, a sealed connection between the capping motor detection component 100 and the vacuum chamber 400 can be achieved.

[0077] In a possible implementation, the capping motor detection component 100 has an installation notch 120 , and the installation notch 120 is used to avoid components connected to the vacuum chamber 400 .

[0078] It is understandable that in the prior art, other components, such as maintenance buttons, are provided above the vacuum chamber 400. The installation notch 120 can ensure smooth connection between the capping motor detection member 100 and the vacuum chamber 400.

[0079] Reference Figure 1 , 5 As shown, the mounting notch 120 is disposed on the periphery of the capping motor detection member 100 , and the structure of the mounting notch 120 is adapted to the components fixed on the vacuum chamber 400 .

[0080] In a possible implementation, the capping motor detection member 100 has at least one first mounting portion 130 , and the first mounting portion 130 is used to be detachably connected to the vacuum chamber 400 .

[0081] It can be understood that the first mounting portion 130 is provided to facilitate the fixation of the capping motor detection member 100 and the vacuum chamber 400. To this end, the first mounting portion 130 can be a screw threadedly connected to the capping motor detection member 100, and the capping motor detection member 100 and the vacuum chamber 400 are locked by the screw. The first mounting portion 130 can also be a through-hole structure, and the capping motor detection member 100 and the vacuum chamber 400 are locked by bolts that are arranged through. Of course, the first mounting portion 130 can also be any other structure that can fix the capping motor detection member 100 and the vacuum chamber 400.

[0082] Reference Figure 1 , 5 As shown, in the present application, the first mounting portion 130 is a through-hole structure, and the number of the first mounting portions 130 is four, and the four first mounting portions 130 are arranged outside the first connecting portion 110 in a rectangular distribution. During installation, the capping motor detection member 100 is covered above the first interface portion 410, and the four first mounting portions 130 correspond to the four corresponding connection points on the vacuum chamber 400, respectively, and the capping motor detection member 100 and the vacuum chamber 400 can be fixed by four bolts.

[0083] The structure of the first mounting portion 130 is adapted to the fixing structure on the existing capping motor. The capping motor detection component 100 and the vacuum chamber 400 can be fixed without changing the structure of the vacuum chamber 400, thereby reducing the difficulty of installing the capping motor detection component 100 and the vacuum chamber 400.

[0084] In a possible implementation, the second connection portion 210 is an annular groove structure, and a second sealing ring 700 is embedded in the second connection portion 210 . The second sealing ring 700 is attached to the second interface portion 420 .

[0085] It can be understood that the second interface part 420 of the vacuum chamber 400 is a through-hole structure opened on the side wall of the vacuum chamber 400, and the second connecting part 210 covers the second interface part 420. The position of the second connecting part 210 can be slightly offset relative to the second interface part 420. To this end, it is necessary to ensure that the second connecting part 210 and the second interface part 420 are sealed and connected.

[0086] Reference Figure 2 , 5 As shown, the wheel detection member 200 is a plate-like structure, the second connection portion 210 is located on one side of the wheel detection member 200, the second connection portion 210 is a rectangular ring-shaped recessed groove structure, a second sealing ring 700 is provided in the second connection portion 210, and part of the second sealing ring 700 is located outside the second connection portion 210. During installation, the second sealing ring 700 contacts the end of the second interface portion 420, and when the wheel detection member 200 and the vacuum chamber 400 are fixed, a sealed connection between the wheel detection member 200 and the vacuum chamber 400 can be achieved.

[0087] In a possible implementation, the wheel detection member 200 has at least one second mounting portion 220 , and the second mounting portion 220 is used to be detachably connected to the vacuum chamber 400 .

[0088] It can be understood that the second mounting portion 220 is to facilitate the fixation of the wheel detection member 200 and the vacuum chamber 400. To this end, the structure of the second mounting portion 220 can refer to the structural setting of the first mounting portion 130, and any method of detachable connection between the wheel detection member 200 and the vacuum chamber 400 can be realized.

[0089] Reference Figure 2 , 5 As shown, in the present application, the second mounting portion 220 is a through-hole structure, and the number of the second mounting portions 220 is four, and the four second mounting portions 220 are arranged outside the second connecting portion 210 in a rectangular distribution. During installation, the wheel detection member 200 is covered outside the second interface portion 420, and the four second mounting portions 220 correspond to the four corresponding mounting points on the vacuum chamber 400, respectively, and the wheel detection member 200 and the vacuum chamber 400 can be fixed by four bolts.

[0090] The structure of the second mounting portion 220 is adapted to the fixing structure on the existing wheel cylinder. The wheel detection member 200 and the vacuum chamber 400 can be fixed without changing the structure of the vacuum chamber 400, thereby reducing the difficulty of installing the wheel detection member 200 and the vacuum chamber 400.

[0091] In a possible implementation, the cover delivery tray detection member 300 has a storage hole 320; the third connecting portion 340 is an annular groove structure, the third connecting portion 340 is opened on the side wall at one end of the storage hole 320, and is arranged close to the storage hole 320, and the third connecting portion 340 is embedded with a third sealing ring 800, and the third sealing ring 800 fits the third interface portion 430.

[0092] It can be understood that the structure of the storage through hole 320 corresponds to the structure on the existing cover delivery tray, ensuring that the cover delivery tray seals the third interface portion 430 under the action of the bottom tray 500. Correspondingly, the position of the third connection portion 340 needs to be adapted to the position of the third interface portion 430, so the third connection portion 340 is arranged close to the storage through hole 320.

[0093] It can be understood that the third interface part 430 of the vacuum chamber 400 is a through-hole structure opened on the side wall of the vacuum chamber 400, and the third connecting part 340 covers the third structural part. The position of the third connecting part 340 can be slightly offset relative to the third interface part 430. Therefore, it is necessary to ensure that the third connecting part 340 is sealed and connected with the third interface part 430.

[0094] Reference Figure 3 , 4As shown in Figures 5 and 6, the cover delivery tray detection member 300 is a plate-like structure, the placement through holes 320 are opened along the two sides of the cover delivery tray detection member 300, the third connection part 340 is located on one side of the cover delivery tray detection member 300, the third connection part 340 is a circular concave groove structure, a third sealing ring 800 is arranged inside the third connection part 340, and part of the third sealing ring 800 is located outside the third connection part 340. During installation, the third sealing ring 800 contacts the end of the third interface part 430, and when the cover delivery tray detection member 300 is fixed to the vacuum chamber 400 under the action of the bottom tray 500, the cover delivery tray detection member 300 and the vacuum chamber 400 can be sealed and connected.

[0095] In a possible implementation, a fourth annular recessed groove 310 is provided on the side wall at the other end of the storage through hole 320 . The fourth recessed groove 310 is used to embed a fourth sealing ring 900 , and the fourth sealing ring 900 fits the tray.

[0096] It can be understood that the upper side of the cover delivery tray detection member 300 is sealed and connected to the vacuum chamber 400, and the lower side of the cover delivery tray detection member 300 is sealed and connected to the bottom tray 500. The bottom tray 500 is a plate-like structure, and a fourth recessed groove 310 is provided to increase the sealing effect between the cover delivery tray detection member 300 and the bottom tray 500.

[0097] Reference Figure 3 , 4 As shown in FIGS. 5 and 6 , the fourth recessed groove 310 is located on the other side of the cover delivery tray detection member 300. The fourth recessed groove 310 is in a circular ring structure. A fourth sealing ring 900 is provided in the fourth recessed groove 310, and a portion of the fourth sealing ring 900 is located outside the fourth recessed groove 310. During installation, the fourth sealing ring 900 contacts the upper surface of the bottom tray 500. When the cover delivery tray detection member 300 is fixed to the vacuum chamber 400 under the action of the bottom tray 500, a sealed connection between the cover delivery tray detection member 300 and the bottom tray 500 can be achieved.

[0098] In a possible implementation, the cover feeding tray detection member 300 has two sliding parts 330 arranged opposite to each other, and the sliding parts 330 are used for sliding connection with the fixing frame of the can seaming machine.

[0099] It can be understood that when the cover delivery tray is used, it is mounted on a fixed frame, and there are two parallel slides on the fixed frame, and the cover delivery tray is located between the two slides. The cover delivery tray moves along the slides under the action of the telescopic cylinder, so that the cover delivery tray can move to the cover receiving position for receiving the cover, and the cover delivery tray after receiving the cover moves to the bottom of the vacuum chamber 400 under the action of the telescopic cylinder, and the bottom tray 500 rises to fix the cover delivery tray and the vacuum chamber 400 against each other.

[0100] To this end, the cover delivery tray detection member 300 is provided with two sliding parts 330 adapted to the cover delivery tray, and the two sliding parts 330 cooperate with the sliding grooves on the fixing frame.
