Description

Technical Field

[0001] The present invention relates to the technical field of paper towel production, and in particular to an intelligent paper towel production and sorting robot. Background Art

[0002] The sealing performance of wet wipe packaging directly affects the shelf life and hygiene of wet wipes. Therefore, sorting in the packaging process, as the last quality checkpoint, is of great significance. The existing technology mainly uses pressure testing to identify problems such as packaging film damage, leaking seals, and seal wrinkles, and sorts and removes them.

[0003] However, in the existing technology, most pressure tests for the sealing of wet wipe packaging are negative pressure tests. During the actual test, the packaged wet wipes are first placed in a sealed chamber, and then the sealed chamber is vacuumed and maintained for a certain period of time. Finally, it is manually or through an image sensor to determine whether the wet wipe packaging has leaks, and the wet wipes with leaks are sorted and removed.

[0004] Although the above method can realize the test operation of the sealing of wet wipes packaging, during the negative pressure test, if the sealing of the wet wipes packaging is unqualified, a large amount of care liquid in the wet wipes packaging box will be drawn out under the action of negative pressure, thereby causing pollution to the test environment. In addition, due to the loss of care liquid, unqualified wet wipes cannot be recycled for secondary packaging, resulting in a waste of resources.

[0005] Therefore, it is necessary to invent an intelligent paper towel production and sorting robot to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent paper towel production and sorting robot, which can effectively sort and reject unqualified wet tissue packaging boxes, and at the same time will not cause the care liquid in the wet tissue packaging box to flow out during the test process, thereby avoiding pollution of the test environment and making it more convenient to subsequently recycle the wet tissues in the unqualified packaging boxes, so as to solve the problem of the negative pressure test process proposed in the above background technology, if the sealing of the wet tissue packaging is unqualified, a large amount of care liquid in the wet tissue packaging box will be drawn out under the action of negative pressure, thereby causing pollution of the test environment. In addition, due to the loss of care liquid, the unqualified wet tissues can no longer be recycled for secondary packaging, resulting in a waste of resources.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent paper towel production and sorting robot, comprising a mounting and fixing assembly, wherein a pressure testing mechanism and a material pushing and outputting mechanism are fixedly provided on the top of the mounting and fixing assembly from left to right, a positioning mechanism is provided between the pressure testing mechanism and the material pushing and outputting mechanism, and a sorting assembly is fixedly provided on the left end of the mounting and fixing assembly; The cam is secured to the bottom of the U-shaped frame by a spring, and the cam is secured to the bottom of the U-shaped frame by a spring.

[0008] Preferably, the installation and fixing assembly includes a workbench, a fixed base is fixedly provided at the bottom of the workbench, and a mounting groove is opened at the left end of the workbench.

[0009] Preferably, a mounting hole is opened on the right side of the top of the workbench, and a first mounting bracket and a second mounting bracket are fixedly arranged on the top of the workbench in sequence from left to right.

[0010] Preferably, the pressurized testing mechanism includes an electric push rod fixedly arranged on the top of the first mounting frame, the output bearing of the electric push rod slides through the first mounting frame and is fixedly connected to a lifting plate, the four corners of the top of the lifting plate are all slid in the vertical direction and penetrated by limiting guide rods, the bottom ends of the four limiting guide rods are commonly fixedly connected to a sealing cover, and the outer side of any one of the limiting guide rods is sleeved with a reset spring A fixedly connected between the lifting plate and the sealing cover.

[0011] Preferably, a piston cylinder is fixedly provided through the top of the sealing cover, a piston rod is fixedly connected to the bottom of the lifting plate, and a piston plate is fixedly connected to the bottom end of the piston rod which slides vertically and fits the inner side of the piston cylinder.

[0012] Preferably, the pushing and outputting mechanism includes a threaded sleeve which is nested and arranged on the inner side of the mounting hole through a bearing rotation, an eccentric wheel is fixedly sleeved on the outer side of the threaded sleeve, a guide frame which is slidably arranged on the inner side of the second mounting frame along the horizontal direction is sleeved on the outer side of the eccentric wheel, and a pushing pad which is slidably arranged on the inner side of the discharge channel is fixedly arranged on the left side of the guide frame.

[0013] Preferably, the inner side of the threaded sleeve is transmission-connected with a screw that slides vertically through the second mounting bracket, and the outer top end of the screw is sequentially sleeved with a limit ring and a return spring B from bottom to top, the limit ring is fixedly connected to the screw, and the return spring B is fixedly connected between the second mounting bracket and the limit ring, and the lifting plate is slidably sleeved on the outer side of the screw along the vertical direction and its top is in contact with the bottom of the limit ring.

[0014] Preferably, the pressurized testing mechanism also includes a PLC controller, and the pushing and outputting mechanism also includes a pressure sensor provided on the top of the pushing pad. The electric push rod and the pressure sensor are both electrically connected to the PLC controller. The PLC controller is used to control the extension and retraction of the output shaft of the electric push rod, and the pressure sensor is used to detect whether a wet tissue box falls on the top of the pushing pad.

[0015] Preferably, the positioning mechanism includes a positioning frame fixedly arranged on the top of the workbench, a feeding port is provided on the top and the front of the positioning frame, and a discharge channel is provided on the bottom of both sides of the positioning frame.

[0016] Preferably, a method for using the intelligent paper towel production and sorting robot is also included, and the method specifically comprises the following steps: S1. Place the collection box for qualified products on the left end of the discharge ramp, and place the collection box for unqualified products on the front of the discharge ramp; S2. The wet tissue packaging boxes to be sorted are fed into the feed port by the conveyor belt, and then enter the positioning frame through the feed port under the action of gravity and are positioned. At the same time, they are detected by the pressure sensor on the top of the push pad. At this time, the PLC controller controls the electric push rod to drive its output shaft to retract; S3, the electric push rod drives its output shaft to retract and drives the lifting plate to move up synchronously. When the lifting plate moves up, it drives the screw to move up on the inside of the threaded sleeve through the limit ring, and at the same time compresses the return spring B. In this process, the screw drives the eccentric wheel to rotate clockwise on the inside of the guide frame through the threaded sleeve. The guide frame drives the pushing pad to move right inside the discharge channel under the drive of the eccentric wheel, thereby moving the pushing pad away from under the wet tissue packaging box. At this time, the wet tissue packaging box falls to the bottom inside the positioning frame, and then the eccentric wheel drives the pushing pad to continue to move left through the guide frame, thereby pushing the wet tissue packaging box, so that the wet tissue packaging box moves to under the sealing cover; S4, the PLC controller controls the electric push rod to drive its output shaft to output. When the output shaft of the electric push rod extends, it drives the lifting plate to move downward continuously. As the lifting plate continues to move downward, the compressed return spring B drives the screw to move downward synchronously through the limit ring until the screw is reset; S5. As the lifting plate continues to move downward, it detaches from the bottom of the reset limit ring. At the same time, the lifting plate moves downward, driving the sealing cover to move downward synchronously through the limit guide rod until the sealing cover is sleeved on the outside of the wet tissue packaging box and fits on the top of the workbench. At this time, due to the obstruction of the workbench, the sealing cover and the limit guide rod no longer move downward. When the lifting plate continues to descend, the reset spring A is continuously compressed, and the piston rod drives the piston plate to continue to descend inside the sealing cover, thereby continuously pressurizing the sealed chamber formed by the sealing cover and the workbench. S6. During the pressurization process, if the wet tissue package is damaged, air enters the wet tissue package and causes it to expand. If the wet tissue package is not damaged, no expansion occurs. S7, the PLC controller controls the electric push rod to drive its output shaft to retract again, and then the electric push rod drives the sealing cover to move up and reset through the lifting plate and the limit guide rod. Then the next wet tissue package box is input into the inner side of the positioning frame again, and the push pad pushes the wet tissue package box to the left. During this process, the wet tissue package box pushes the wet tissue package box after the previous test, so that it slides through the installation slot to the top of the discharge inclined plate; S8. The discharging inclined plate guides the tested wet tissue packaging box. If it does not expand, it passes through the avoidance channel between the discharging inclined plate and the upper U-shaped frame and falls into the collection box at the left end of the discharging inclined plate. If it expands, it cannot pass through the avoidance channel, so it enters the collection box in front of the discharging inclined plate under the guidance of the upper U-shaped frame to complete sorting and removal.

[0017] Technical effects and advantages of the present invention: The present invention is provided with a pressure testing mechanism and a sorting component, so that the pressure testing mechanism can be used to cover and pressurize the wet tissue packaging box, thereby allowing air to enter the interior of the unqualified wet tissue packaging box and cause it to expand. The subsequent sorting component can sort and remove unqualified products under the action of gravity according to whether the wet tissue packaging box is expanded. Compared with the existing technology, the present invention can effectively sort and remove unqualified wet tissue packaging boxes, and at the same time, the care liquid in the wet tissue packaging box will not flow out during the test process, thereby avoiding pollution of the test environment and making it more convenient to subsequently recycle the wet tissues in the unqualified packaging box.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The present invention provides Figure 1-Figure 5 The intelligent tissue production and sorting robot shown is designed to perform sealing inspection on wet tissue packaging boxes and automatically sort out defective products. Its core structure consists of five parts: a mounting and fixing component 1, a pressurized testing mechanism 2, a material pushing and output mechanism 3, a positioning mechanism 4, and a sorting component 5. These components work together to complete the entire process from feeding and testing to sorting.

[0022] like Figure 2 As shown, the installation and fixing component 1 includes a workbench 11, which is made of high-strength alloy material and has a wear-resistant surface treatment. It is used to carry other mechanisms and provide a plane for testing and conveying. A fixed base 12 is fixed at the bottom of the workbench 11 and fixed to the ground by bolts to reduce vibration during equipment operation and ensure test accuracy. A mounting groove 13 is provided at the left end of the workbench 11, and a mounting hole 14 is provided on the right side of the top of the workbench 11. A first mounting bracket 15 and a second mounting bracket 16 are fixed on the top of the workbench 11 from left to right, which are used to fix the pressurized test mechanism 2 and the push-out mechanism 3 respectively. The height and spacing are optimized to ensure that the actions of each mechanism do not interfere with each other.

[0023] like Figure 3As shown, the pressurized testing mechanism 2 includes an electric push rod 21 fixedly arranged on the top of the first mounting frame 15, and the output bearing of the electric push rod 21 slides through the first mounting frame 15 and is fixedly connected to the lifting plate 22. The four corners of the top of the lifting plate 22 slide in the vertical direction and are provided with a limiting guide rod 23. The bottom ends of the four limiting guide rods 23 are commonly fixedly connected to a sealing cover 24. A rubber sealing ring is installed on the inner wall of the sealing cover 24 to ensure air tightness. The outer side of any limiting guide rod 23 is sleeved with a return spring A25 fixedly connected between the lifting plate 22 and the sealing cover 24. A piston cylinder 26 is fixedly provided on the top of the sealing cover 24, and a piston rod 27 is fixedly connected to the bottom of the lifting plate 22. The bottom end of the piston rod 27 is fixedly connected to a piston plate 28 that slides in the vertical direction and fits the inner side of the piston cylinder 26.

[0024] By setting up the above structure, when the electric push rod 21 drives its output shaft to descend, the sealing cover 24 is driven to descend synchronously through the lifting plate 22 and the limiting guide rod 23 until the sealing cover 24 is pressed against the top of the workbench 11. At this time, a closed space for testing is formed inside the sealing cover 24. At the same time, due to the obstruction of the workbench 11, the sealing cover 24 and the limiting guide rod 23 cannot move further downward. At this time, as the lifting plate 22 continues to descend, the return spring A25 is continuously compressed. At the same time, the lifting plate 22 drives the piston plate 28 to continue to descend inside the piston cylinder 26 through the piston rod 27, thereby continuously pressurizing the closed space.

[0025] like Figure 4 As shown, the pushing and outputting mechanism 3 includes a threaded sleeve 31 which is nested and arranged on the inner side of the mounting hole 14 through a bearing rotation. An eccentric wheel 32 is fixedly sleeved on the outer side of the threaded sleeve 31. A guide frame 33 which is slidably arranged on the inner side of the second mounting frame 16 in the horizontal direction is sleeved on the outer side of the eccentric wheel 32. A pushing pad 34 which is slidably arranged on the inner side of the discharge channel 43 is fixedly arranged on the left side of the guide frame 33. The inner side of the threaded sleeve 31 is transmission-connected with a screw 35 which slides through the second mounting frame 16 in the vertical direction. The outer top end of the screw 35 is sleeved with a limit ring 36 and a return spring B37 in sequence from bottom to top. The limit ring 36 is fixedly connected to the screw 35. The return spring B37 is fixedly connected between the second mounting frame 16 and the limit ring 36. The lifting plate 22 is slidably sleeved on the outer side of the screw 35 in the vertical direction and its top is in contact with the bottom of the limit ring 36.

[0026] By setting the above structure, when the limit ring 36 moves up, it drives the screw 35 to move up on the inner side of the threaded sleeve 31, and at the same time compresses the return spring B37. During this process, the screw 35 drives the eccentric wheel 32 to rotate clockwise on the inner side of the guide frame 33 through the threaded sleeve 31. Driven by the eccentric wheel 32, the guide frame 33 drives the pushing pad 34 to move right on the inner side of the discharge channel 43, thereby moving the pushing pad 34 away from under the wet tissue packaging box. At this time, the wet tissue packaging box falls on the bottom inside the positioning frame 41, and then the eccentric wheel 32 drives the pushing pad 34 to move continuously to the left through the guide frame 33, thereby pushing the wet tissue packaging box, so that the wet tissue packaging box moves to under the sealing cover 24.

[0027] It should be added that the pressurized testing mechanism 2 also includes a PLC controller, and the pushing and outputting mechanism 3 also includes a pressure sensor provided on the top of the pushing pad 34. The electric push rod 21 and the pressure sensor are both electrically connected to the PLC controller. The PLC controller is used to control the extension and retraction of the output shaft of the electric push rod 21, and the pressure sensor is used to detect whether a wet tissue box falls on the top of the pushing pad 34.

[0028] By setting up the above structure, it is convenient to use the pressure sensor to test whether a wet tissue box falls on the top of the pushing pad 34. If so, an electrical signal is sent to the PLC controller, and the PLC controller controls the electric push rod 21 to drive its output shaft to retract. When the electric push rod 21 drives its output shaft to retract, it drives the lifting plate 22 to move up synchronously. When the lifting plate 22 moves up, it drives the limit ring 36 to move up.

[0029] like Figure 4 As shown, the positioning mechanism 4 includes a positioning frame 41 fixedly arranged on the top of the workbench 11. The inner wall of the positioning frame 41 is made of smooth and wear-resistant plastic material, which performs preliminary positioning of the packaging box to ensure that it is in a correct posture when entering the test position. A feed port 42 is provided on the top and front of the positioning frame 41. The feed port 42 is connected to the upstream conveyor belt. The wet tissue packaging box falls into the positioning frame 41 by gravity. The size of the feed port 42 is slightly larger than the specification of the packaging box, which ensures smooth feeding and avoids position displacement. A discharge channel 43 is provided on the bottom of both sides of the positioning frame 41. The width of the discharge channel 43 matches the thickness of the packaging box, providing a movement path for the pushing pad 34 of the pushing output mechanism, and at the same time limiting the side tipping of the packaging box during the pushing process.

[0030] By setting up the above structure, after the wet tissue packaging boxes to be sorted are input to the feed port 42 by the conveyor belt, the wet tissue packaging boxes enter the positioning frame 41 through the feed port 42 under the action of gravity. At this time, the inner wall of the positioning frame 41 roughly positions the wet tissue packaging boxes, so that when they are subsequently pushed out from the inside of the discharge channel 43, they can accurately enter under the sealing cover 24.

[0031] like Figure 5 As shown, the sorting component 5 includes a discharging inclined plate 51 fixedly connected to the inner side of the mounting groove 13, and the inclination angle of the discharging inclined plate 51 is set to 30°. A lower U-shaped frame 52 is fixedly provided at the bottom of the discharging inclined plate 51, and adjusting guide rods 53 are fixedly provided at both ends of the inner side of the lower U-shaped frame 52. The outer sides of the two adjusting guide rods 53 are slidably sleeved with an upper U-shaped frame 54 for guiding unqualified wet tissue packaging boxes. An avoidance channel for avoiding qualified wet tissue packaging boxes is formed between the discharging inclined plate 51 and the lower U-shaped frame 52, and locking bolts 55 are penetrated at both ends of the outer side of the lower U-shaped frame 52. The locking bolts 55 are threadedly connected to the lower U-shaped frame 52 and their ends are tightly pressed against the outer side of the upper U-shaped frame 54. The locking bolts 55 are set to lock the upper U-shaped frame 54 so that after loosening the locking bolts 55, the position of the upper U-shaped frame 54 can be adjusted along the adjusting guide rods 53 to adapt to qualified packaging boxes of different specifications.

[0032] By setting up the above structure, after the tested wet tissue packaging box is pushed and falls on the top of the discharge inclined plate 51, the discharge inclined plate 51 guides the tested wet tissue packaging box. If it does not expand, it passes through the avoidance channel between the discharge inclined plate 51 and the upper U-shaped frame 54 and falls on the collection box at the left end of the discharge inclined plate 51. If it expands, it cannot pass through the avoidance channel, so it enters the collection box on the front of the discharge inclined plate 51 under the guidance of the upper U-shaped frame 54 to complete sorting and rejection. Since gravity is directly used to achieve sorting and rejection, the use cost and failure rate are lower.

[0033] The present invention also discloses a method for using an intelligent paper towel production and sorting robot, which specifically includes the following steps: S1. Place the collection box for qualified products on the left end of the discharge inclined plate 51, and place the collection box for unqualified products on the front of the discharge inclined plate 51; S2. The wet tissue packaging box to be sorted is fed into the feed port 42 by the conveyor belt, and then enters the positioning frame 41 through the feed port 42 under the action of gravity and is positioned. At the same time, it is detected by the pressure sensor on the top of the push pad 34. At this time, the PLC controller controls the electric push rod 21 to drive its output shaft to retract; S3, when the electric push rod 21 drives its output shaft to retract, it drives the lifting plate 22 to move up synchronously. When the lifting plate 22 moves up, it drives the screw 35 to move up inside the threaded sleeve 31 through the limit ring 36, and at the same time compresses the return spring B37. During this process, the screw 35 drives the eccentric wheel 32 to rotate clockwise inside the guide frame 33 through the threaded sleeve 31. The guide frame 33 drives the pushing pad 34 to move right inside the discharge channel 43 under the drive of the eccentric wheel 32, thereby moving the pushing pad 34 away from under the wet tissue packaging box. At this time, the wet tissue packaging box falls to the bottom inside the positioning frame 41, and then the eccentric wheel 32 drives the pushing pad 34 to continue to move left through the guide frame 33, thereby pushing the wet tissue packaging box, so that the wet tissue packaging box moves to under the sealing cover 24; S4. The PLC controller controls the electric push rod 21 to drive its output shaft to output. When the output shaft of the electric push rod 21 extends, it drives the lifting plate 22 to continuously move downward. As the lifting plate 22 continues to move downward, the compressed return spring B37 drives the screw rod 35 to move downward synchronously through the limit ring 36 until the screw rod 35 is reset. S5. As the lifting plate 22 continues to move downward, the lifting plate 22 is separated from the bottom of the reset limit ring 36. At the same time, when the lifting plate 22 moves downward, the sealing cover 24 is driven to move downward synchronously through the limit guide rod 23 until the sealing cover 24 is sleeved on the outside of the wet tissue packaging box and fits on the top of the workbench 11. At this time, due to the obstruction of the workbench 11, the sealing cover 24 and the limit guide rod 23 no longer move downward. When the lifting plate 22 continues to descend, the return spring A25 is continuously compressed. At the same time, the piston rod 27 drives the piston plate 28 to continue to descend inside the sealing cover 24, thereby continuously pressurizing the sealed chamber formed by the sealing cover 24 and the workbench 11. S6. During the pressurization process, if the wet tissue package is damaged, air enters the wet tissue package and causes it to expand. If the wet tissue package is not damaged, no expansion occurs. S7, the PLC controller controls the electric push rod 21 to drive its output shaft to retract again, and then the electric push rod 21 drives the sealing cover 24 to move up and reset through the lifting plate 22 and the limit guide rod 23. Then the next wet tissue package box is input into the inner side of the positioning frame 41 again, and the pushing pad 34 pushes the wet tissue package box to the left. During this process, the wet tissue package box pushes the wet tissue package box after the previous test, so that it slides through the installation slot 13 to the top of the discharge inclined plate 51; S8. The discharging inclined plate 51 guides the tested wet tissue packaging box. If it has not expanded, it passes through the avoidance channel between the discharging inclined plate 51 and the upper U-shaped frame 54 and falls into the collection box at the left end of the discharging inclined plate 51. If it has expanded, it cannot pass through the avoidance channel, so it enters the collection box on the front of the discharging inclined plate 51 under the guidance of the upper U-shaped frame 54 to complete sorting and removal.

[0034] To sum up, this application adopts positive pressure testing instead of traditional negative pressure testing to avoid the care liquid in unqualified products being extracted due to negative pressure, thereby protecting the testing environment. At the same time, since the unqualified products do not lose the care liquid, they can be directly recycled for secondary packaging to reduce waste. In addition, no manual intervention is required from feeding to sorting, which is suitable for high-speed production lines. In addition, the upper U-shaped frame and pushing parameters can be adjusted to adapt to wet tissue packaging boxes of different sizes and materials.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.

The intelligent paper towel production and sorting robot according to claim 7, characterized in that: The pressurized testing mechanism (2) further includes a PLC controller, and the material pushing and outputting mechanism (3) further includes a pressure sensor provided on the top of the material pushing pad (34). The electric push rod (21) and the pressure sensor are both electrically connected to the PLC controller. The PLC controller is used to control the extension and retraction of the output shaft of the electric push rod (21), and the pressure sensor is used to detect whether a wet tissue packaging box falls on the top of the material pushing pad (34).

9. The intelligent paper towel production and sorting robot according to claim 8, characterized in that: The positioning mechanism (4) includes a positioning frame (41) fixedly arranged on the top of the workbench (11), a feeding port (42) is provided on the top and front of the positioning frame (41), and a discharge channel (43) is provided on the bottom of both sides of the positioning frame (41).

10. The intelligent paper towel production and sorting robot according to claim 9, characterized in that: The invention also includes a method for using the intelligent paper towel production and sorting robot, the method specifically comprising the following steps: S1, placing a collection box for qualified products on the left end of the discharge inclined plate (51), and placing a collection box for unqualified products on the front of the discharge inclined plate (51); S2, the wet tissue packaging box to be sorted is fed into the feed port (42) by the conveyor belt, and then enters the positioning frame (41) through the feed port (42) under the action of gravity to be positioned, and is detected by the pressure sensor on the top of the push pad (34). At this time, the PLC controller controls the electric push rod (21) to drive its output shaft to retract; S3, the electric push rod (21) drives the lifting plate (22) to move upward synchronously when its output shaft retracts. When the lifting plate (22) moves upward, it drives the screw (35) to move upward on the inner side of the threaded sleeve (31) through the limiting ring (36), and compresses the return spring B (37). During this process, the screw (35) drives the eccentric wheel (32) to rotate clockwise on the inner side of the guide frame (33) through the threaded sleeve (31). The guide frame (33) drives the push plate (34) to move right on the inner side of the discharge channel (43) under the drive of the eccentric wheel (32), thereby moving the push plate (34) away from the bottom of the wet tissue packaging box. At this time, the wet tissue packaging box falls on the inner bottom of the positioning frame (41). Then, the eccentric wheel (32) drives the push plate (34) to move left continuously through the guide frame (33), thereby pushing the wet tissue packaging box, so that the wet tissue packaging box moves to the bottom of the sealing cover (24); S4, the PLC controller controls the electric push rod (21) to drive its output shaft to output, and when the output shaft of the electric push rod (21) extends, it drives the lifting plate (22) to continuously move downward. As the lifting plate (22) continues to move downward, the compressed return spring B (37) drives the screw rod (35) to move downward synchronously through the limit ring (36) until the screw rod (35) is reset; S5. As the lifting plate (22) continues to move downward, the lifting plate (22) is separated from the bottom of the limit ring (36) after reset. At the same time, when the lifting plate (22) moves downward, the sealing cover (24) is driven to move downward synchronously through the limit guide rod (23) until the sealing cover (24) is sleeved on the outside of the wet tissue packaging box and fits with the top of the workbench (11). At this time, due to the obstruction of the workbench (11), the sealing cover (24) and the limit guide rod (23) no longer move downward. When the lifting plate (22) continues to descend, the reset spring A (25) is continuously compressed. At the same time, the piston rod (27) drives the piston plate (28) to continue to descend inside the sealing cover (24), thereby continuously pressurizing the sealed chamber formed by the sealing cover (24) and the workbench (11); S6. During the pressurization process, if the wet tissue package is damaged, air enters the wet tissue package and causes it to expand. If the wet tissue package is not damaged, no expansion occurs. S7, the PLC controller controls the electric push rod (21) to drive its output shaft to retract again, thereby causing the electric push rod (21) to drive the sealing cover (24) to move upward and reset through the lifting plate (22) and the limit guide rod (23), and then the next wet tissue packaging box is input into the inner side of the positioning frame (41) again, and the pushing pad (34) pushes the wet tissue packaging box to the left. During this process, the wet tissue packaging box pushes the wet tissue packaging box after the previous test, so that it slides through the installation slot (13) to the top of the discharge inclined plate (51); S8, the discharging inclined plate (51) guides the wet tissue packaging box after the test. If it does not expand, it passes through the avoidance channel between the discharging inclined plate (51) and the upper U-shaped frame (54) and falls into the collection box at the left end of the discharging inclined plate (51). If it expands, it cannot pass through the avoidance channel, so it enters the collection box on the front of the discharging inclined plate (51) under the guidance of the upper U-shaped frame (54) to complete sorting and removal.
