Description

Technical Field

[0001] This utility model relates to the field of packaging testing technology, specifically to a testing mechanism for packaging lines. Background Technology

[0002] A packaging line is a general term for a system. Most manufacturers have their own packaging production line, which typically consists of several different packaging machines and conveyor belts. Products in production or already processed are transported to the packaging line for packaging. After packaging, they are sent out as complete, transportable products. During the packaging process, to ensure product quality standards are met, empty package inspections are often performed to prevent the production and sale of empty packages. Currently, existing packaging lines often require a large amount of manual labor for random checks after the products are packaged to ensure packaging efficiency and pass rates. Manual inspection is time-consuming, labor-intensive, and incurs high labor costs. Utility Model Content

[0003] To address the technical problem of low efficiency in manual sampling inspection, this utility model proposes a detection mechanism for packaging lines. By displacing the contact element downwards or upwards, the other end of the transmission component will also displace upwards or downwards. The displacement actuator will identify this change, eliminating the need for manual sampling inspection and improving efficiency.

[0004] The technical solution adopted by this utility model is as follows: a detection mechanism for a packaging line includes a frame, a support assembly, a displacement sensor, a transmission assembly, and a contact element. The support assembly is movably mounted on the frame. A displacement sensor is installed at one end of the support assembly, and a transmission assembly is rotatably mounted at the other end of the support assembly. One end of the transmission assembly is correspondingly arranged with a displacement actuator, and the other end of the transmission assembly is rotatably connected to the contact element.

[0005] Optionally, the transmission assembly includes a first transmission rod, a second transmission rod, a third transmission rod, and a transmission plate. The first transmission rod is rotatably connected to the support assembly. One end of the first transmission rod is fastened to the second transmission rod, and the other end of the first transmission rod is fastened to the third transmission rod. One end of the transmission plate is rotatably connected to the support assembly, and the other end of the transmission plate is correspondingly disposed with a displacement sensor. The lower surface of the transmission plate abuts against the upper surface of the third transmission rod.

[0006] Optionally, it also includes a first spring, one end of which is connected to the third transmission rod, and the other end of which is inclined upward and connected to the support assembly.

[0007] Optionally, a second spring is also included, one end of which is connected to the lower surface of the transmission plate, and the other end of which is inclined downward and connected to the support assembly.

[0008] Optionally, the support assembly includes a support plate, a first support rod, a second support rod, and a sensor frame. The frame is provided with a slide rail in the vertical direction. The support plate is slidably connected to the slide rail. The first support rod is perpendicularly connected to the support plate. The outer peripheral wall of the first support rod is provided with a first slider. The first slider is connected to the second support rod. The outer peripheral wall of the second support rod is provided with a second slider. The second slider is connected to the sensor frame. The sensor frame is rotatably connected to the first transmission rod.

[0009] Optionally, the contact element is a roller, which is rotatably connected to the second transmission rod via a bearing.

[0010] Optionally, the sensor frame has a cylinder on its side wall, and the telescopic end of the cylinder is connected to a mounting block, on which the displacement sensor is mounted.

[0011] Optionally, the support plate is provided with a solenoid valve connected to the cylinder.

[0012] The beneficial effects of this utility model are as follows: The frame is installed on both sides of the conveyor line. During operation, the conveyor line continuously transports the packaged goods through the conveyor belt. The contact parts roll in contact with the upper surface of the packaged goods. Under normal circumstances, the contact parts roll smoothly. When the packaged goods are empty or the quantity of products in the packaged goods does not meet the standard, the contact parts move downward or upward, causing the other end of the transmission component to move upward or downward. The displacement transmitter identifies this change through the spring and feeds it back as an electrical signal to the host computer, thereby logically judging the thickness change value of the product. Then, in conjunction with the corresponding program, the online detection function is completed, eliminating the need for manual sampling, improving efficiency, and reducing costs.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] like Figure 1As shown, this embodiment discloses a detection mechanism for a packaging line, including a frame 1, a support assembly, a displacement sensor 2, a transmission assembly, and a contact element 3. The support assembly is movably mounted on the frame 1. The displacement sensor 2 is installed at one end of the support assembly, and the transmission assembly is rotatably mounted at the other end. One end of the transmission assembly is correspondingly arranged with a displacement actuator, and the other end of the transmission assembly is rotatably connected to the contact element 3. The frame 1 is installed on both sides of the conveyor line. During operation, the conveyor line continuously transports packaged goods via a conveyor belt. The contact element 3 rolls in contact with the upper surface of the packaged goods. Under normal circumstances, the contact element 3 rolls smoothly. When the packaged goods are empty or the quantity of products in the packaged goods does not meet the standard, the contact element 3 moves downward or upward, causing the other end of the transmission assembly to move upward or downward. The displacement actuator recognizes this change and feeds back an electrical signal to the host computer, thereby logically determining the thickness change value of the product. Then, in conjunction with the corresponding program, the online detection function is completed, eliminating the need for manual sampling and improving efficiency.

[0018] like Figure 1 and 2 As shown, the transmission assembly includes a first transmission rod 4, a second transmission rod 5, a third transmission rod 6, and a transmission plate 7. The first transmission rod 4 is rotatably connected to the support assembly. One end of the first transmission rod 4 is fastened to the second transmission rod 5, and the other end of the first transmission rod 4 is fastened to the third transmission rod 6. One end of the transmission plate 7 is rotatably connected to the support assembly, and the other end of the transmission plate 7 is correspondingly positioned with the displacement sensor 2. The lower surface of the transmission plate 7 abuts against the upper surface of the third transmission rod 6. The two ends of the first transmission rod 4 are rotatably connected to the support assembly via a rotating shaft. When the contact member 3 causes the second transmission rod 5 to change displacement, the first transmission rod 4 acts as a lever, causing the third transmission rod 6 to change displacement, which in turn causes the end of the transmission plate 7 corresponding to the displacement sensor 2 to change displacement upwards or downwards.

[0019] In this embodiment, as Figure 2 As shown, it also includes a first spring 8, one end of which is connected to the third transmission rod 6, and the other end of which is inclined upwards and connected to the support assembly. The first spring 8 can bypass the transmission plate 7 and connect to the third transmission rod 6. The upward tension of the first spring 8 ensures that the contact element 3 located at the other end of the first transmission rod 4 is always in contact with the packaged item. It also includes a second spring 9, one end of which is connected to the lower surface of the transmission plate 7, and the other end of which is inclined downwards and connected to the support assembly. The second spring 9 provides a downward tension to the transmission plate 7, so that the transmission plate 7 is always in contact with the third transmission rod 6, ensuring that changes in the contact element 3 can be transmitted to the transmission plate 7.

[0020] like Figure 1As shown, the support assembly includes a support plate 10, a first support rod 11, a second support rod 12, and a sensor frame 13. The frame 1 has a slide rail along the vertical direction. The support plate 10 is slidably connected to the slide rail. The first support rod 11 is perpendicularly connected to the support plate 10. A first slider 14 is provided on the outer peripheral wall of the first support rod 11, and the first slider 14 is connected to the second support rod 12. A second slider 15 is provided on the outer peripheral wall of the second support rod 12, and the second slider 15 is connected to the sensor frame 13. The sensor frame 13 is rotatably connected to the first transmission rod 4. The frame 1, support plate 10, first support rod 11, second support rod 12, and sensor frame 13 are vertically connected in sequence. The support plate 10 drives the transmission assembly to move along the frame 1 (i.e., the z-axis direction). The first slider 14 drives the transmission rod assembly to move along the first support rod 11 (i.e., the y-axis direction). The second slider 15 drives the transmission assembly to move along the second support rod 12 (i.e., the x-axis direction), thus enabling the detection of packaging materials of different heights and sizes. The driving method of the support plate 10, the first slider 14, and the second slider 15 is not limited to linear motor or cylinder 17.

[0021] In this embodiment, the contact element 3 is a roller, which is rotatably connected to the second transmission rod 5 via a bearing 16. The inner ring of the bearing 16 mates with the outer peripheral wall of the second transmission rod 5, and the outer ring of the bearing 16 mates with the inner peripheral wall of the roller. Compared to other shapes, the roller-type contact element 3 reduces the friction between the contact element 3 and the packaging. In other embodiments, the surface of the contact element that contacts the packaging can be a plane or a straight line.

[0022] like Figure 1 As shown, a cylinder 17 is provided on the side wall of the sensor frame 13. A mounting block 18 is connected to the telescopic end of the cylinder 17, and the displacement sensor 2 is mounted on the mounting block 18. The cylinder 17 can adjust the height of the displacement sensor 2, facilitating the detection of changes in the transmission plate 7. A solenoid valve 19 connected to the cylinder 17 is provided on the support plate 10. The encoder input signal is sent to the PLC (host computer), and the PLC outputs a signal to the solenoid valve 19, which controls the extension or retraction of the cylinder 17.
