Abstract
Description
Technical Field
[0001] This application relates to the field of thermos cup testing technology, and in particular to a multi-station adaptive thermos cup vacuum layer sealing performance testing device. Background Technology
[0002] The vacuum seal of a thermos cup is a key indicator affecting its heat preservation performance. Traditional testing methods mainly use the water bath method, which involves immersing the thermos cup in hot or cold water and observing whether bubbles appear on the cup wall or temperature changes to determine if the vacuum layer is leaking. Although this method is simple to operate, the characteristics of the water bath require waiting for more than 30 minutes to observe stable results, making it difficult to meet the rapid quality inspection needs of production lines. At the same time, some testing devices on the market use non-water bath methods; however, these devices can only test thermos cups of a preset size. When it is necessary to switch production targets on a large scale, the current equipment is often not directly adaptable and requires the replacement of a large number of parts. Therefore, how to solve the above problems is the purpose of this application.
[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention
[0004] Based on this, this application provides a multi-station adaptive vacuum layer sealing test device for thermos cups to solve one of the above-mentioned technical problems.
[0005] The technical solution adopted by this application to solve its technical problem is a multi-station adaptive vacuum layer sealing performance testing device for thermos cups, including: a workbench with several stations for placing thermos cups; a sealing module movably disposed above the stations, which detects the sealing performance of the thermos cups; a control unit for determining the internal air pressure and temperature of the thermos cups; and a flexible heating module movably disposed on both sides of the stations, which includes two follower frames, a follower block, and a heating film disposed between the two follower blocks. The follower blocks are rotatably disposed on the follower frames, and elastic components are provided on the follower blocks to limit their rotation and reset them.
[0006] In some embodiments, the sealing module includes a longitudinally movable cylinder on which a pressure plate and a sealing gasket are disposed.
[0007] In some embodiments, the sealing module is further provided with an air pressure sensor, which is able to communicate with the air inside the thermos.
[0008] In some embodiments, the flexible heating module further includes a movable seat, the bottom of which is provided with a cylinder for driving the movable seat to move toward the work station, the follower frame is rotatably mounted on the movable seat, and the movable seat is provided with a torsion spring for driving the follower frame to reset.
[0009] In some embodiments, the follower frame is provided with a limit block to limit the maximum rotation range of the follower frame.
[0010] In some embodiments, a connecting block extends from one side of the follower frame connected to the follower block, and a movable groove is provided on the follower block, with the connecting block rotatably disposed within the movable groove.
[0011] In some embodiments, the elastic component is a spring, and the length of the connecting block is greater than the depth of the movable groove. Therefore, there is a gap between the follower block and the follower frame, and the elastic component is disposed between the follower block and the follower frame and distributed on both sides of the connecting block.
[0012] In some embodiments, a movable support plate is provided above one of the flexible heating modules, and the side of the support plate near the workstation has a U-shaped or V-shaped recess that can fit against the wall of the thermos cup.

[0014] The beneficial effects of this application are as follows: the exterior of the stainless steel thermos cup is heated by a flexible heating module, and the cup mouth is sealed by a sealing module and the changes in air pressure inside the thermos cup are monitored to detect whether the vacuum jacket is in a vacuum state. At the same time, the movable follower frame and follower block can adaptively fit onto the exterior of the thermos cup when the flexible heating module is released from the outer surface of the thermos cup.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.
[0022] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a multi-station 11 adaptive vacuum layer sealing performance testing device for thermos cups, mainly including: a workbench 1, on which several workstations 11 are provided for placing thermos cups; a sealing module 2, movably disposed above the workstations 11, for detecting the sealing performance of the thermos cups through the movable sealing module 2; a control unit, for determining the internal air pressure and temperature of the thermos cups; and a flexible heating module 3, movably disposed on both sides of the workstations 11, which includes two follower frames 31 and follower blocks 32 and a heating film 33 disposed between the two follower blocks 32. The follower blocks 32 are rotatably disposed on the follower frames 31, and the follower blocks 32 are provided with elastic members 35 for limiting the rotation of the follower blocks 32 and resetting them; the flexible heating module 3 can move towards the workstations 11 and adaptively cooperate with and fit against the outer wall of the thermos cups for heating.
[0023] Specifically, when a thermos cup needs to be tested, the thermos cup is first placed on station 11 with its mouth facing upwards, and the sealing module 2 is activated to seal the mouth of the thermos cup. The control unit judges the sealing status inside the thermos cup and provides feedback through a display screen or other means. During the sealing process of the sealing module 2, the flexible heating modules 3 on both sides of station 11 move towards the thermos cup at the same time. When the flexible heating module 3 moves towards the thermos cup, the heating film 33 contacts the thermos cup, and under the continuous feeding of the flexible heating unit, the follower frame 31 and the follower block 32 rotate at the same time, causing the contact angle of the heating film 33 to change, so that the heating film 33 is tightly attached to the lower half of the thermos cup. The mobility of the follower frame 31 and the follower block 32 allows the flexible heating module 3 to adapt to thermos cups of different sizes.
[0024] As an explanation, the heating temperature of the heating film 33 can be set from 60℃ to 90℃, depending on the test standards and the material of the cup.
[0025] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.
[0026] Specifically, the sealing module 2 includes a longitudinally movable cylinder. The cylinder is equipped with a pressure plate and a sealing gasket. The pressure applied by the cylinder ensures tight contact with the cup opening, completely sealing the air inside the cup and preventing leakage.
[0027] The sealing module 2 is also equipped with an air pressure sensor, which can communicate with the air inside the thermos cup to monitor the air pressure inside the cup in real time and feed it back to the control unit.
[0028] Specifically, the flexible heating module 3 also includes a movable seat 34. A cylinder is provided at the bottom of the movable seat 34 to drive the movable seat 34 to move towards the work station 11. The follower frame 31 is rotatably mounted on the movable seat 34. A torsion spring 341 is provided on the movable seat 34 to drive the follower frame 31 to reset. With this configuration, the movable seat 34 can drive the flexible heating module 3 to move towards the center of the work station 11.
[0029] Specifically, in order to prevent the heating film 33 from expanding too much due to the excessive torque of the torsion spring 341, thus reducing the heating effect, a limit block 342 is provided on the follower frame 31 to limit the maximum rotation range of the follower frame 31.
[0030] Preferably, the two follower frames 31 are initially in an extended trumpet shape. This arrangement allows the follower frames 31 to have more room to move when the flexible heating module 3 is fed to the workstation 11.
[0031] Preferably, in order to limit the rotation of the follower frame 31 and the follower block 32, a connecting block 311 extends from the side of the follower frame 31 connected to the follower block 32, and a movable groove 321 is provided on the follower block 32, and the connecting block 311 is rotatably disposed in the movable groove 321.
[0032] Reference Figure 3 As shown, the elastic component 35 is a spring, and the length of the connecting block 311 is greater than the depth of the movable groove 321. Therefore, there is a gap between the follower block 32 and the follower frame 31. The elastic component 35 is disposed between the follower block 32 and the follower frame 31 and distributed on both sides of the connecting block 311. With this arrangement, the elastic component 35 enables the follower block 32 to immediately reset when it is removed from the thermos cup, ready for the next use.
[0033] Reference Figure 4 As shown, a movable support plate 4 is provided above one of the flexible heating modules 3. The support plate 4 has a U-shaped or V-shaped recess 41 on the side near the workstation 11, which can conform to the wall of the thermos cup. When the outer diameter of the thermos cup to be tested is fixed, the support plate 4 only needs to be adjusted to a suitable position and fixed before initial use or before replacing a thermos cup of a different size. This ensures that the bottom position of the thermos cup is relatively fixed when placed in the workstation 11, facilitating accurate positioning and clamping of the flexible heating module 3 and the sealing module 2. No adjustment is required during batch testing of thermos cups of the same size.
[0034] Reference Figure 4 As shown, a positioning reference line is provided on the workstation 11, and the thermos cup is placed at the center of the positioning reference line. The positioning reference line can help the thermos cup to be positioned.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
