Description

Technical Field

[0001] The present invention belongs to the technical field of packaging detection, and in particular relates to a packaging detection jig. Background Art

[0002] Currently, after product production and packaging, it is usually necessary to use a packaging inspection fixture to detect whether the product packaging is leaking;

[0003] The existing application number is 202221030265.2, which discloses a novel packaging inspection jig comprising a base plate, support plates mounted below the base plate near the four corners, a movable shaft rotatably mounted between two adjacent support plates, and two rollers disposed front and rear on each of the two movable shafts, and support rods mounted above the base plate near the four corners. This packaging inspection jig uses multiple pressure plates to test the sealing properties of products downward, and can inspect multiple products at a time.

[0004] Application number 202022490682.2 discloses a novel packaging inspection jig comprising a bracket, a support platform fixedly connected to a side wall of the bracket, and a test box fixedly connected to a side wall of the support platform, and a detection mechanism including an electro-hydraulic push rod. This packaging inspection jig inspects the package by placing the package on the test box and pressing down the package with the electro-hydraulic push rod.

[0005] The above existing packaging inspection jigs all perform air leakage detection on inflated packages by pressing down. These existing packaging inspection jigs all require the package on the inspection table to be removed and a new package to be placed. The continuity of the inspection is low, and since the package sizes of different batches and products are inconsistent, when a limiting mechanism is not set, the package may be pressed to one side during the downward inspection, resulting in inaccurate inspection. However, the placement plate in the above existing technology is provided with a groove for placing the product. When the product is large, it is not easy to place the product package in the groove. Therefore, the size of the product package to be inspected is limited. When a leaking package appears, the user needs to manually remove the leaking package and separate it from other non-leaking packages, which is a relatively complicated operation. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a packaging inspection jig that can continuously inspect packaging and set a limiting structure to limit the position of product packaging, so that the product packaging can be moved more accurately to the lower part of the pressing component, thereby improving the applicability of packages of different sizes, and can divert leaking packages from non-leaking packages, making it easier to separate leaking packages from non-leaking packages.

[0028] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1 and attached Figure 2As shown, a packaging inspection jig includes a conveyor 1, a top frame 2 is provided on the upper part of the conveyor 1, and support rods 3 are fixedly installed at the four corners between the frame of the conveyor 1 and the top frame 2, a controller 4 is fixedly installed on the upper part of the top frame 2, a cylinder 5 is fixedly installed on the middle part of the upper side of the top frame 2, and the output rod of the cylinder 5 passes through the top frame 2, a limited stop frame assembly 6 is installed on the conveyor 1, a guide plate assembly 7 is installed on the lower part of the top frame 2, and sensor mounting frames 8 are fixedly installed on the left and right sides of the front and rear parts of the frame of the conveyor 1, and a laser sensor 9 is installed on the sensor mounting frame 8.

[0029] In this embodiment, combined with the Figure 3 As shown, a detection pressure plate 51 is fixedly installed at the lower end of the output rod of the cylinder 5, and first limit rods 52 are fixedly installed on both sides of the upper part of the detection pressure plate 51. The first limit rods 52 pass through the through holes opened in the top frame 2. The user places the product package on the conveyor 1 and conveys the product from the direction away from the guide plate 75 to the direction toward the guide plate 75. When the laser sensor 9 detects that there is a product package being conveyed on the conveyor 1, the detection pressure is set through the controller 4, and the product package moves to the lower part of the detection pressure plate 51. The cylinder 5 drives the detection pressure plate 51 to descend, applies pressure to the product package, and detects whether the product package is leaking. At this time, the first limit rod 52 rises and falls along the top frame 2, which plays a role in limiting the detection pressure plate 51.

[0030] In this embodiment, combined with the Figure 4 and attached Figure 5As shown, the limit stop frame assembly 6 includes a mounting plate 61, a limit protrusion 611 is integrated in the middle of the side of the mounting plate 61 facing the conveyor 1, a rack 66 is provided through the limit protrusion 611, and slide rails 62 are fixedly installed on both sides of the side of the mounting plate 61 facing the conveyor 1, and a slider 63 is slidably connected to the slide rail 62, and each of the sliders 63 is pin-mounted with a side baffle 64 at the front, and a main baffle 65 is pin-mounted between the two side baffles 64, and the main baffle 65 is fixedly installed with one end of the rack 66, and a second limit rod 651 is fixedly installed side by side on the side of the main baffle 65 facing the mounting plate 61, and the second limit rod 651 passes through the through holes opened on both sides of the middle of the mounting plate 61, and a motor mounting frame 69 is fixedly installed on the side of the mounting plate 61 facing away from the conveyor 1, and a first motor 68 is fixedly installed on the motor mounting frame 69. A gear 67 is fixedly installed at the output shaft of 8, and the gear 67 is meshed with the rack 66. The main baffle 65 is arranged perpendicular to the rack 66. The user installs the limit stop frame assembly 6 on the front and rear sides of the conveyor 1, and the first motor 68 drives the gear 67 to rotate, so that the rack 66 moves forward or backward, and the rack 66 drives the main baffle 65 to move forward or backward, thereby adjusting the distance between the front and rear main baffles 65 so that the distance is adapted to the size of the product packaging. The two main baffles 65 limit the position of the product packaging, so that the product packaging can be more accurately moved to the lower part of the detection pressure plate 51, thereby improving the applicability of packages of different sizes, and locking the movement of the main baffle 65. The other end of the side baffle 64 moves along the slide rail 62 through the slider 63, and the side baffle 64 guides the product packaging so that the product packaging enters between the two main baffles 65.

[0031] In this embodiment, combined with the Figure 6 As shown, the guide plate assembly 7 includes a mounting frame 71 and a reduction gear 72. A second motor 73 is installed at the input shaft of the reduction gear 72. A rotating shaft 74 is installed on the lower end coupling of the output shaft of the reduction gear 72. The longitudinal bearing of the rotating shaft 74 is installed inside the mounting frame 71. A guide plate 75 is fixedly installed on one side of the lower end of the rotating shaft 74. When the user detects that the package is leaking, as the conveyor 1 transports the package, the guide plate 75 can send the leaking package down from one side of the conveyor 1. When the package is not leaking, the second motor 73 drives the rotating shaft 74 to rotate through the reduction gear 72, and rotates the guide plate 75 to the other side, so that the package that is not leaking is sent down from the other side of the conveyor 1, thereby diverting the leaking package from the package that is not leaking, making it easier to separate the leaking package from the package that is not leaking.

[0032] In this embodiment, specifically, a slide groove is provided on one side of the rack 66 , and an integrated protrusion is provided inside the limiting protrusion 611 , and the protrusion is slidably provided in the slide groove.
