DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] like Figure 1 As shown, this embodiment provides a hot pot base packaging bag air leakage detection device, including a bottom plate 1, a clamping mechanism 2, and a suction cup mechanism 3.

[0028] Specifically, Figure 1 As shown, the bottom plate 1 is in the shape of a rectangular plate, and a first conveyor belt 11 and a second conveyor belt 12 are spaced apart above it. The length directions of the first conveyor belt 11 and the second conveyor belt 12 are parallel to the length direction of the bottom plate 1. The first conveyor belt 11 is used to convey the hot pot soup base to be tested and the hot pot soup base that has passed the test, and the second conveyor belt 12 is used to convey the hot pot soup base that has failed the test.

[0029] Specifically, Figure 1 and Figure 2As shown, the clamping mechanism 2 includes a driving frame 21 and a clamping plate 22. The driving frame 21 is door-shaped, including a horizontal plate and vertical plates vertically connected to the two ends of the lower surface of the horizontal plate, and the length direction of the horizontal plate is parallel to the length direction of the bottom plate 1; the driving frame 21 moves along the width direction and height direction of the bottom plate 1 and is arranged above the first conveyor belt 11, and the clamping plates 22 have a length direction parallel to the width direction of the bottom plate 1 and are arranged at intervals along the length direction of the bottom plate 1 and the spacing is adjustable. One end of the clamping plate 22 is located directly below the driving frame 21 and the other end is arranged toward the second conveyor belt 12. More specifically, one end of the clamping plate 22 is spaced one by one from the vertical plates and the spacing is adjustable; when the driving frame 21 moves, the clamping plate 22 moves with the driving frame 21.

[0030] Specifically, Figure 1 , Figure 2 , Figure 4 As shown, the suction cup mechanism 3 includes a vacuum chamber 31, a suction cup 32, and a vacuum pump 33. The vacuum chamber 31 has two vacuum chambers 31 located at the upper and lower sides of the clamping plate 22, and both are arranged to move along the width direction and the length direction of the bottom plate 1. There are multiple suction cups 32, which are respectively connected to the lower part of the vacuum chamber 31 above the clamping plate 22 and the upper part of the vacuum chamber 31 below the clamping plate 22. More specifically, in this example, each vacuum chamber 31 is connected to two suction cups 32, and the opening surfaces of the suction cups 32 are parallel to the upper surface of the bottom plate 1, and are located The suction cup 32 on the vacuum bin 31 above the clamping plate 22 is opened downward, and the suction cup 32 on the vacuum bin 31 below the clamping plate 22 is opened upward; the suction cup 32 is made of hard material and a sealing ring 34 is provided at the edge of the opening. There are two vacuum pumps 33, which are arranged on the bottom plate 1 and matched one by one with the vacuum bins 31. A vacuum hose 35 is connected between the matched vacuum pumps 33 and the vacuum bins 31. The vacuum pump 33 is used to provide a vacuum environment for the matched vacuum bin 31 through the vacuum hose 35.

[0031] When working, the device processes the square hot pot soup base that has just been vacuum-packed. The hot pot soup base to be tested is conveyed to the bottom of the clamping plate 22 by the first conveyor belt 11, and the driving frame 21 is moved so that the two clamping plates 22 are respectively located on both sides of the hot pot soup base to be tested. The spacing between the clamping plates 22 is adjusted so that the clamping plates 22 contact the two side edges of the hot pot soup base to be tested and clamp them fixedly. The driving frame 21 is moved again so that the driving frame 21 carries the hot pot soup base to be tested and is located between the first conveyor belt 11 and the second conveyor belt 12.

[0032] Move the vacuum bin 31 so that the suction cups 32 on the vacuum bin 31 contact the upper surface and the lower surface of the hot pot base packaging bag respectively, start the vacuum pump 33, and the vacuum pump 33 evacuates the vacuum bin 31 through the vacuum hose 35 so that the suction cups 32 suck the hot pot base. Adjust the spacing of the clamping plates 22 so that the clamping plates 22 leave the two sides of the hot pot base. At this time, since the suction cups 32 are made of hard material, the hot pot base can be fixed between the suction cups 32.

[0033] Since the internal environment of the leaking packaging bag is not a vacuum, there is a gap between the hot pot base and the packaging bag and relative displacement is easy to occur. Therefore, two driving forces in opposite directions but parallel to the width direction of the bottom plate 1 are applied to the vacuum bin 31 to drive the vacuum bin 31 to move. If the vacuum bin 31 can move under the action of the driving force, and the packaging bag can be displaced relative to the hot pot base driven by the suction cup 32, then the packaging bag has a leak and the test result is unqualified; if the vacuum bin 31 cannot move under the action of the driving force, then the packaging bag has no leak and the test result is qualified. Specifically, there is a certain limit to the size of the driving force, that is, it is greater than the minimum force required to drive the leaking packaging bag and the hot pot base to produce relative movement, and at the same time is less than the minimum force required to forcibly drive the non-leaking packaging bag and the hot pot base to produce relative movement.

[0034] If the test result is qualified, the driving frame 21 and the clamping plate 22 are used to move the hot pot base back to the first conveyor belt 11; if the test result is unqualified, the vacuum bin 31 below the hot pot base is deflated to stop the suction cup 32 on the lower surface of the hot pot base packaging bag from adsorbing, and the vacuum bin 31 above the hot pot base is moved so that the unqualified hot pot base moves to the second conveyor belt 12 through the suction cup 32 adsorbed on the upper surface of the hot pot base. At this time, the vacuum bin 31 above the hot pot base is deflated to stop the suction cup 32 on the upper surface of the hot pot base packaging bag from adsorbing, and the unqualified hot pot base stays on the second conveyor belt 12.

[0035] Preferably, Figure 2 and Figure 4As shown, both side walls of the vacuum bin 31 are connected with mounting plates 36, and the side of the mounting plates 36 facing away from the suction cup 32 is connected with a first spring 37 along the height direction of the bottom plate 1, the first spring 37 located on the same vacuum bin 31 is connected with the same hanging plate 38, and the side of the hanging plate 38 facing away from the vacuum bin 31 is connected with a first force sensor 39 along the height direction of the bottom plate 1, the first force sensor 39 is connected with a carrier plate 310, and a fixing plate 311 is installed on the side of the carrier plate 310 facing the hanging plate 38, each mounting plate 36 has two sliding holes passing through it along the height direction of the bottom plate 1, and each fixing plate 311 is connected with two vertical rods 312 along the height direction of the bottom plate 1 on the side facing the mounting plate 36, the vertical rods 312 are slidably arranged in the sliding holes one by one, and the carrier plates 310 are movably arranged along the height direction and width direction of the bottom plate 1.

[0036] Preferably, Figure 2 , Figure 4 , Figure 5 As shown, a side of the carrier plate 310 facing away from the hanging plate 38 is provided with a gantry 313 at intervals along the height direction of the bottom plate 1, the gantry 313 includes a horizontal portion and two vertical portions respectively connected to the horizontal portion facing the side of the carrier plate 310, a sliding rod 314 parallel to the width direction of the bottom plate 1 is connected between the vertical portions connected to the same horizontal portion, a sliding block 315 is slidably sleeved on the sliding block 314, a sliding block 316 is connected to the side of the sliding block 315 facing the carrier plate 310, two second springs 317 are connected to both sides of each sliding block 316 along the width direction of the bottom plate 1, and the second spring 317 connected to one side of the same sliding block 316 is connected to the same first mounting bar 318 A second spring 317 connected to the other side of the same slide plate 316 is connected to the same second mounting bar 319, a second force sensor 320 is connected between the first mounting bar 318 and one of the vertical portions on the gantry 313 where it is located along the width direction of the base plate 1, the second mounting bar 319 is installed on the other vertical portion of the gantry 313 where it is located, a first linear cylinder 321 is provided on the slide plate 316 along the height direction of the base plate 1, a driving shaft of the first linear cylinder 321 is connected to the corresponding carrier plate 310, and the first linear cylinder 321 is used to drive the carrier plate 310 to move; the gantry 313 is arranged to move along the width direction of the base plate 1.

[0037] Preferably, Figure 1 and Figure 3As shown, the first conveyor belt 11 and the second conveyor belt 12 are respectively provided with a first protrusion 13 and a second protrusion 14 on both sides opposite to each other, the first protrusion 13 is provided with a first support rod 15, the second protrusion 14 is provided with a second support rod 16, the upper ends of the first support rod 15 and the second support rod 16 are connected to the same support bar 17, the lower surface of the support bar 17 is provided with a first electric screw 322 along the width direction of the bottom plate 1, the first electric screw 322 is matched with a first matching block 323, and the first matching block 323 is connected to the position A gantry frame 313 above the driving frame 21, a second electric screw 18 is provided on the bottom plate 1 along its width direction, the second electric screw 18 is matched with a second matching block 19, the second matching block 19 is connected to the gantry frame 313 below the driving frame 21, the first electric screw 322 is used to drive the gantry frame 313 above the driving frame 21 to move through the first matching block 323, and the second electric screw 18 is used to drive the gantry frame 313 below the driving frame 21 to move through the second matching block 19.

[0038] During operation, after the suction cup 32 is attached to the upper and lower surfaces of the hot pot base packaging bag, the two first linear cylinders 321 are started to shrink the driving shaft of the first linear cylinder 321, and the first spring 37 is pulled through the carrier plate 310, the first force sensor 39, and the hanging plate 38. At the same time, the first spring 37 provides an upward pulling force for the vacuum chamber 31 through the mounting plate 36. If the packaging bag is not leaking, the vacuum chamber 31 will not move; if the packaging bag is leaking, the vacuum chamber 31 will drive the packaging bag of the hot pot base to separate from the hot pot base through the suction cup 32 under the action of the pulling force, so as to facilitate the subsequent movement of the vacuum chamber 31 along the width of the bottom plate 1 to avoid the hot pot base from adhering to the packaging bag to affect the test results; here A first spring 37 is provided for converting the displacement of the carrier plate 310 into a pulling force on the vacuum chamber 31, so that the magnitude of the pulling force can be adjusted more accurately. Meanwhile, the first force sensor 39 can display the magnitude of the pulling force in real time, ensuring that the magnitude of the pulling force can pull the leaking packaging bag without causing damage to the non-leaking packaging bag. More specifically, due to the gravity of the vacuum chamber 31 itself, the pulling force required for the vacuum chamber 31 located above the hot pot base is larger, and the pulling force required for the vacuum chamber 31 located below the vacuum chamber 31 is smaller. Therefore, the contraction degree of the driving shaft of the first linear cylinder 321 located above the vacuum chamber 31 is larger, and the contraction degree of the first linear cylinder 321 located below the vacuum chamber 31 is smaller.

[0039] The first electric screw rod 322 and the second electric screw rod 18 are started, and the two portal frames 313 are driven to move in opposite directions through the first matching block 323 and the second matching block 19 respectively. The second springs 317 on both sides of the slide plate 316 are stretched and contracted respectively to provide a pulling force for the slide plate 316, and the pulling force is the driving force of the vacuum bin 31, and the driving force of the vacuum bin 31 can be displayed in real time on the second force sensor 320. When the driving force reaches the preset value, the portal frame 313 does not move, that is, the vacuum bin 31 does not move at this time, then the packaging bag does not produce relative displacement with the hot pot base, and the hot pot base packaging bag does not leak. The test results is qualified; when the driving force does not reach the preset value, but the gantry 313 moves, that is, the vacuum chamber 31 moves at this time, then the packaging bag and the hot pot base produce relative displacement, the hot pot base packaging bag leaks, and the test result is unqualified; more specifically, the second spring 317 is provided here to convert the displacement of the gantry 313 into a driving force for the vacuum chamber 31, which can more accurately adjust the size of the driving force, and at the same time provide a preset value of the driving force to ensure that the driving force can cause the leaking packaging bag and the hot pot base to produce relative displacement without causing damage to the non-leaking packaging bag, and can protect the non-leaking hot pot base packaging bag during testing.

The third electric screw 23 is used to drive the driving frame 21 to move along the width direction of the base plate 1, and the second linear cylinder 25 is used to drive the driving frame 21 to move along the height direction of the base plate 1.

[0041] Preferably, Figure 2 As shown, two third linear cylinders 27 are provided on the driving frame 21 along the length direction of the base plate 1 , and the driving shafts of the third linear cylinders 27 are connected to the clamping plates 22 one by one.
