[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0025] like Figure 1-5As shown, the automatic weighing and rejection device for tea gift boxes includes a rejection device frame 1, an automatic transmission roller 2 installed on the rejection device frame 1, the automatic transmission roller 2 transports the tea gift boxes, the end of the rejection device frame 1 is attached to the defective product collection device 3, a feeding weighing inlet 4 is installed on the rejection device frame 1, a rejection component 5 is installed at the bottom of the rejection device frame 1, the upper end of the rejection component 5 extends through the automatic transmission roller 2 to the upper end of the rejection device frame 1, and an installation component 6 is provided on the rejection component 5.

[0026] The rejection assembly 5 includes a drive motor 51 fixed on the outer wall of the bottom end of the rejection device frame 1, a telescopic rod 52 slidably connected in the drive motor 51, two sets of auxiliary support plates 53 connected to the end of the telescopic rod 52, a rejection push plate 54 inserted into the auxiliary support plate 53, a slot 55 opened in the rejection push plate 54, and a camera sensor 56 connected to the auxiliary support plate 53 and inserted into the slot 55 at its front end.

[0027] When the tea gift box is conveyed to the rejection component 5 by the automatic conveying roller 2, the camera sensor 56 detects the tea gift box through the slot 55. If it is a defective product, the sensor starts the drive motor 51 to work. The drive motor 51 drives the telescopic rod 52 to move, which in turn drives the rejection push plate 54 to move through the auxiliary support plate 53. The rejection push plate 54 pushes the defective tea gift box to the defective product collection device 3 for collection.

[0028] It is worth noting that there are two sets of auxiliary support plates 53 symmetrically arranged. The distance between the two sets of auxiliary support plates 53 is equal to the width of one roller on the automatic transmission roller 2. The two sets of auxiliary support plates 53 are symmetrically distributed, which can balance the force on the rejection push plate 54, avoid the push plate tilting or jamming due to unilateral force application, and ensure the stability when pushing defective products.

[0029] The slot 55 is located in the middle of the rejection push plate 54. The front end of the camera sensor 56 is inserted into the slot 55. The front end of the camera sensor 56 is set as a camera, so that the camera of the camera sensor 56 is located on the center line of the push plate and faces the gift box on the transmission path, ensuring that the detection field of view is unobstructed and improving the detection accuracy.

[0030] The auxiliary support plate 53 is provided with mounting components 6 on both sides. The rejection push plate 54 is inserted into the auxiliary support plate 53. The auxiliary support plate 53 is fixed to the rejection push plate 54 through the mounting components 6. The rejection push plate 54 cooperates with the insertion slot 62 of the auxiliary support plate 53 through the insertion rod 61, so as to achieve quick disassembly and assembly without complicated tools and reduce maintenance time.

[0031] The mounting assembly 6 includes a plug rod 61 fixed to the outer wall of the rejection push plate 54, a plug groove 62 opened in the auxiliary support plate 53 and plugged into the plug rod 61, a limiting groove 63 opened in the plug rod 61, an auxiliary plate 64 installed on the side wall of the auxiliary support plate 53, a sliding groove 65 opened in the auxiliary plate 64, a slider 66 slidably connected in the sliding groove 65, a limiting rod 67 connected to the slider 66 and plugged into the auxiliary plate 64, a return spring 68 wound around the outer wall of the limiting rod 67, and a pull ring 69 fixed to the outer end wall of the limiting rod 67.

[0032] When the removal push plate 54 needs to be replaced due to wear, the worker only needs to pull the pull ring 69 outward, causing the pull ring 69 to move the limit rod 67 outward. The limit rod 67 slides outward in the slide groove 65 through the slider 66. During the sliding process, the return spring 68 is squeezed and deformed until the inner end of the limit rod 67 moves out of the limit groove 63, releasing the fixation on the plug rod 61. Until both pull rings 69 at both ends are pulled outward to the outermost end, the removal push plate 54 is pulled outward, causing the removal push plate 54 to move the plug rod 61 out of the plug groove 62 to complete the disassembly. Similarly, for installation, the pull ring 69 is pulled outward to the outermost end beforehand, and then the plug rod 61 is plugged into the plug groove 62. Finally, the pull ring 69 is loosened, and the restoring force generated by the elasticity of the return spring 68 pushes the limit rod 67 back to its original position and plugs it into the limit groove 63 to form a fixed position.

[0033] It is worth noting that the diameter of the limiting rod 67 is equal to the diameter of the limiting groove 63, and the length of the slide groove 65 is greater than the depth of the limiting groove 63. The diameter of the limiting rod 67 matches the limiting groove 63 to ensure that there is no looseness after insertion and to prevent the push plate from falling off due to vibration during high-speed movement.

[0034] One end of the reset spring 68 is connected to the outer wall of the slider 66, and the other end of the reset spring 68 is connected to the inner wall of the auxiliary plate 64. The reset spring 68 automatically resets the limit rod 67. During installation, it is only necessary to align and insert the rod, and then release the rod to complete the fixation, reducing the difficulty of manual alignment and positioning error.

[0035] The pull ring 69 is designed in the shape of a ring, and the outer wall of the pull ring 69 is provided with anti-slip texture to increase the friction of pulling the limit rod and avoid operation errors caused by slippage.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as defined by the appended claims and their equivalents.
