[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] The utility model provides a heavy-duty product swing arm rejection device, which classifies qualified and unqualified products that have been inspected and flowed into the front-end product inspection device 6. The rejection device includes a frame 1, a chain plate transmission component 2, a swing arm rejection component 3, a lower slide plate 4 and a control component 5. After the heavy-duty product passes through the device, the qualified product will be conveyed along the conveying direction, and the unqualified product will change direction and leave the transmission mechanism along the lower slide plate 4 due to the guidance of the swing arm rejection component 3. Heavy-duty products refer to products of 20kg to 100kg.

[0028] like Figure 1 As shown, the chain conveyor assembly 2 is installed on the frame 1, the swing arm rejection assembly 3 is installed on one side of the frame 1, the lower slide plate 4 is installed on the other side opposite to the swing arm rejection assembly 3, and the control assembly 5 is installed in the frame 1.

[0029] The chain plate transmission assembly 2 comprises a chain plate 20 and a transmission device, and the transmission device drives the chain plate 20 to move. The friction coefficient of the chain plate 20 is smaller than that of the conveyor belt, which is conducive to the promotion of heavy products.

[0030] like Figure 3 As shown, the swing arm rejection assembly 3 includes a power mechanism 30 and a swing arm 31. The power mechanism 30 includes a cylinder support 300 and a cylinder 301. One end of the cylinder 301 is mounted on the cylinder support 300. Its output shaft is rotatably connected to the middle of the swing arm 31 through a first rotating shaft 310. One end of the swing arm 31 is mounted on a second rotating shaft 311. The second rotating shaft 311 is mounted on two seat bearings 10. The two seat bearings 10 and the cylinder support 300 are mounted on the same side of the frame 1. In order to ensure that heavy products of 20kg to 100kg can be pushed, the cylinder diameter of the cylinder 301 is 60mm to 80mm.

[0031] like Figure 2As shown, when the output shaft of the cylinder 301 is in the extended state, the swing arm 31 and the transmission direction of the chain plate 20 form an acute angle, and the two ends of the swing arm 31 are respectively located on both sides of the frame 1; when the output shaft of the cylinder 301 is in the retracted state, the swing arm 31 is parallel to the transmission direction of the chain plate transmission assembly 2 and is located on one side of the frame 1.

[0032] The lower slide plate 4 is a triangular prism structure, one side of which is installed close to the frame 1, and has a firm structure, suitable for heavy products; its length is greater than the length of the swing arm 31 to prevent the product from being missed when being rejected.

[0033] like Figure 4 As shown, the control component 5 is connected to the detection device 6 and the swing arm rejection component 3. The upper detection device 6 provides a detection signal to the control component 5, and the control component 5 obtains a signal of whether the product is qualified and controls the state of the cylinder 301 in the swing arm rejection component 3.

[0034] When the product is qualified, the cylinder 301 will be in a retracted state, and the swing arm 31 connected to the end of the cylinder 301 will be parallel to the transmission direction of the chain plate 20, so as not to interfere with the movement of the product on the chain plate conveying assembly 2 along the rotation direction of the chain plate 20, and the product will smoothly enter the next production line for continued production. When the product is unqualified, the control component 5 will control the cylinder 301 to be in an extended state when the product enters the chain plate conveying assembly 2, and the swing arm 31 connected to the output shaft of the cylinder 301 will rotate around the second rotating shaft 311, so that the swing arm 31 and the transmission direction of the chain plate 20 form an angle (acute angle). When the product is transmitted in the chain plate conveying assembly 2, due to the obstruction and guidance of the swing arm 31, the product cannot continue to be transmitted in the rotation direction of the chain plate 20, and will enter the lower slide plate 4 due to the guidance of the swing arm 31, thereby reaching the storage area for unqualified products. After a certain period of time, when the product has left the transmission mechanism of the chain plate 20, the control component 5 will control the cylinder 301 to be in a retracted state to enter the next stage of rejection action.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
