[0033] 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.

[0034] Reference Figure 1 A leak detection device for soft-pack packaging, as described in this embodiment of the invention, is applied to a filling machine and includes an upright device 110, an extrusion device 120, a conveyor line 101, and a control device. The filling machine 100 is used to fill soft-pack workpieces 103. The filling machine 100 has a discharge channel 102 for discharging the filled soft-pack workpieces 103. The upright device 110 is installed on one side of the discharge channel 102 and can receive the soft-pack workpieces 103. The extrusion device 120 is located downstream of the upright device 110. The extrusion device 120 is used to extrude the soft-pack workpieces 103 and test the pressure during extrusion. The control device determines whether leakage occurs in the soft-pack workpieces 103 during the extrusion process. The conveyor line 101 is used to transport the soft-pack workpieces 103. This achieves a fully automated leak detection process without manual intervention, which is beneficial for improving the accuracy of detection and the consistency of products. Furthermore, the soft-pack workpieces 103 move continuously during the extrusion detection process, thereby achieving a highly efficient leak detection process and improving detection efficiency.

[0035] Reference Figure 2 Specifically, the discharge channel 102 is inclined, and the filled soft-pack workpiece 103 slides down the discharge channel 102 on the filling equipment 100 into the upright device 110. The upright device 110 is located between the conveyor line 101 and the discharge channel 102. The upright device 110 includes a tilting plate 111, a lifting cylinder 112, and a guide plate 113. The tilting plate 111 is pivotally connected to the conveyor line 101, the lifting cylinder 112 is located at the lower part of the tilting plate 111, and the guide plate 113 is installed on the conveyor line 101. The guide plate 113 can be adjusted in installation position along the width direction of the conveyor line 101. It can be understood that when the soft-pack workpiece 103 slides down from the discharge channel 102 onto the tilting plate 111, the lifting cylinder 112 can lift the tilting plate 111 to rotate the inclined soft-pack workpiece 103, so that the soft-pack workpiece 103 is placed upright on the conveyor line 101 and abuts against the guide plate 113. Understandably, in actual production, the position of the guide plate 113 is adjusted according to the thickness of the soft-pack workpiece 103 so that the upright soft-pack workpiece 103 can contact the guide plate 113 and prevent the soft-pack workpiece 103 from tipping over.

[0036] Furthermore, the erecting device 110 is also equipped with a baffle plate 114 and a translation cylinder 115. The translation cylinder 115 can drive the baffle plate 114 to move along the width direction of the conveyor line 101. It can be understood that when the translation cylinder 115 drives the baffle plate 114 to extend towards the discharge channel 102, the baffle plate 114 can cover the upper surface of the conveyor line 101, causing the soft-packaged workpiece 103 falling from the discharge channel 102 to contact the baffle plate 114. The continuously running conveyor line 101 cannot drive the soft-packaged workpiece 103, thus preventing the soft-packaged workpiece 103 from being conveyed downstream, achieving the material blocking function. When the translation cylinder 115 drives the baffle plate 114 to retract, the soft-packaged workpiece 103 falling from the discharge channel 102 can land on the conveyor line 101, achieving feeding.

[0037] Reference Figure 3 and Figure 4 It is understood that the extrusion device 120 includes a first conveying mechanism 121 and a second conveying mechanism 122 located on both sides of the width of the conveyor line 101. Both the first conveying mechanism 121 and the second conveying mechanism 122 are equipped with a pressure conveyor belt 131 and multiple pressure rollers, with the pressure conveyor belt 131 wrapped around the outer circumference of the pressure rollers. Further, the pressure rollers include a first pressure roller 123 and a second pressure roller 124 located at opposite ends of the pressure conveyor belt 131 along the moving direction of the soft-pack workpiece 103, with the first pressure roller 123 located upstream of the second pressure roller 124. Specifically, the extrusion device 120 is equipped with a mounting plate 126, and the first pressure roller 123 and the second pressure roller 124 are floatingly connected to the mounting plate 126, and the first pressure roller 123 and the second pressure roller 124 can move along the width direction of the conveyor line 101. Simultaneously, the first pressure roller 123 and the second pressure roller 124 are respectively connected to pressure sensors 130, which can obtain pressure values ​​based on the positional changes of the first pressure roller 123 and the second pressure roller 124. Furthermore, along the moving direction of the flexible workpiece 103, there are multiple third pressure rollers 125 between the first pressure roller 123 and the second pressure roller 124. The third pressure rollers 125 are pivotally connected to the mounting plate 126, so that the pressure conveyor belt 131 can continuously apply pressure to the flexible workpiece 103.

[0038] Understandably, conveyor line 101 transports the flexible packaged workpiece 103 between the first conveyor mechanism 121 and the second conveyor mechanism 122. Conveyor line 101 operates continuously, and the pressure conveyor belts 131 of the first and second conveyor mechanisms 121 and 122 operate synchronously and at the same speed as conveyor line 101. The flexible packaged workpiece 103 passes through the extrusion device 120, and the pressure conveyor belt 131 continuously applies pressure to the flexible packaged workpiece 103. Furthermore, a rejection mechanism (not shown in the figure) is provided downstream of the extrusion device 120. The rejection mechanism is used to remove the flexible packaged workpiece 103 that has leaked.

[0039] Understandably, when the flexible packaging workpiece 103 enters the extrusion device 120, the pressure sensor 130 connected to the first pressure roller 123 can measure the first pressure value. After the flexible packaging workpiece 103 passes through the extrusion device 120 and is extruded for a period of time, it passes the location of the second pressure roller 124, where the pressure sensor 130 connected to the second pressure roller 124 can measure the second pressure value. The control device is electrically connected to the two pressure sensors 130 and can receive the first and second pressure values. It compares the first and second pressure values. If the first pressure value is significantly greater than the second pressure value (exceeding the preset error range), it indicates that the flexible packaging workpiece 103 has leaked during the extrusion process. At this time, the control device controls the rejection mechanism to reject the leaking flexible packaging workpiece 103. If the difference between the first and second pressure values ​​is within the preset error range, it indicates that the first and second pressure values ​​are equal, and the flexible packaging workpiece 103 has not leaked during the extrusion process.

[0040] Reference Figure 3 The extrusion device 120 also includes a frame 127 and an adjusting plate 129. Both the first conveying mechanism 121 and the second conveying mechanism 122 are equipped with mounting plates 126, and the pressure roller and pressure sensor 130 are located on the mounting plates 126. The mounting plate 126 is mounted on the adjusting plate 129. The frame 127 is equipped with a slide rail 128, which extends vertically along its length. The adjusting plate 129 is slidably connected to the slide rail 128. It is understood that the adjusting plate 129 can move along the height direction of the frame 127 via the slide rail 128 to adjust its mounting position, thereby adjusting the height position of the first conveying mechanism 121 and the second conveying mechanism 122 to accommodate different product heights, which improves production flexibility.

[0041] Furthermore, the second conveying mechanism 122 is fixedly installed on the frame 127, and the adjusting plate 129 where the first conveying mechanism 121 is located is slidably connected to the frame 127. Thus, the first conveying mechanism 121 can move along the width direction of the conveying line 101, thereby adjusting the distance between the first conveying mechanism 121 and the second conveying mechanism 122 according to the size of different soft-pack workpieces 103, which is beneficial to improving production flexibility.

[0042] 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.
