[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figs. 1-3 The spring processing feeding mechanism shown includes a frame 1. Two feeding components are rotatably mounted on the inner side of the frame 1. A drive box 3 for driving one of the feeding components to rotate is mounted on the side end of the frame 1. A lifting component for driving the other feeding component to rise and fall is mounted on the top of the frame 1. The feeding components include a conveying roller 2 and a conveying wheel 4. The conveying wheel 4 of one feeding component is connected to the lifting component through the conveying roller 2. The conveying wheel 4 of the other feeding component is connected between the drive box 3 and the frame 1 through the conveying roller 2. The drive box 3 contains conventional electrical equipment (e.g., a geared motor) for driving the conveying roller 2 to rotate and is electrically connected to a controller and power supply through conventional technical means.

[0027] Regarding conveyor wheel 4, specifically 2 and... Fig. 3As shown in the figure, the conveying wheel 4 comprises two symmetrical conical tables 41, and the diameters of the two conical tables 41 gradually increase from the end close to each other to the end far away from each other. The symmetrical conical tables 41 can be suitable for different diameters of straight strip spring steel materials, and the conical tables 41 do not need to be replaced when feeding different diameters of straight strip spring steel materials, and the use is more convenient.

[0028] In addition, compared with the conventional arc-shaped concave surface, the two inclined surfaces formed by the symmetrical conical tables 41 in the scheme can make the contact points of the straight strip spring steel materials of different diameters with the inclined surfaces different, thereby reducing the wear.

[0029] The conveying wheel 4 further comprises two positioning bosses 42, and the two positioning bosses 42 are coaxially fixed to the ends far away from each other of the two conical tables 41, respectively. The conveying roller 2 is divided into two roller bodies located on the two sides of the conveying wheel 4, and the two roller bodies each comprise a fixed roller 21, a positioning sleeve 22 and a compression spring 23. The fixed roller 21 of one feeding assembly is rotationally connected with the rack 1 and connected with the drive box 3, and the fixed roller 21 of the other feeding assembly is connected with the lifting assembly. The positioning sleeve 22 is coaxially and slidingly sleeved on the outside of the fixed roller 21 and connected with the fixed roller 21 through the compression spring 23, and the positioning sleeve 22 is slidingly sleeved with the positioning boss 42.

[0030] The above arrangement facilitates the replacement of the conveying wheel 4. For example, when the conveying wheel 4 is severely worn, the positioning sleeve 22 can be manually slid away from the conveying wheel 4 until the positioning sleeve 22 is separated from the positioning boss 42, and then the conveying wheel 4 can be removed.

[0031] The lifting assembly comprises a lifting driving device 6 mounted on the top end of the rack 1 and a lifting frame 5 mounted on the bottom output end of the lifting driving device 6, and the fixed roller 21 is rotationally connected with the lifting frame 5. The lifting driving device 6 can adopt a conventional power driving device, such as a hydraulic cylinder or an electric push rod.

[0032] Considering that some impurities such as steel chips are attached to the surface of the conical table 41 during the conveying of the straight strip spring steel material, thereby accelerating the wear of the conical table 41, the inner bottom end of the rack 1 and the inner top end of the lifting frame 5 are both provided with a cleaning brush 7 in contact with the surface of the conical table 41. During the rotation of the conical table 41, the cleaning brush 7 can be used to brush off the impurities such as steel chips attached to the surface of the conical table 41, so as to keep the surface of the conical table 41 smooth, thereby facilitating the prolongation of the service life of the conical table 41.

[0033] The end of the positioning boss 42 away from the conical table 41 is integrally provided with an auxiliary positioning block 43, the end of the fixing roller 21 close to the conveying wheel 4 is provided with an auxiliary positioning groove 24 matched with the auxiliary positioning block 43, and the auxiliary positioning groove 24 extends to the arc side of the fixing roller 21, and the matching of the auxiliary positioning block 43 and the auxiliary positioning groove 24 can quickly align the positioning boss 42 and the fixing roller 21, and facilitate the installation of the conveying wheel 4.

[0034] In order to further facilitate the alignment between the positioning boss 42 and the fixing roller 21, the auxiliary positioning groove 24 is L-shaped, the vertical section of the fixing roller 21 and the positioning boss 42 is square, and the positioning boss 42 can be inserted from any one of the two slots of the L-shaped auxiliary positioning groove 24.

[0035] The end of the positioning boss 42 away from the conical table 41 and the end of the auxiliary positioning block 43 away from the positioning boss 42 are provided with a guide chamfer 44, which increases the fault tolerance when the positioning boss 42 is inserted into the positioning sleeve 22 and the auxiliary positioning block 43 is inserted into the auxiliary positioning groove 24, and the insertion is more convenient.

[0036] The working principle of the utility model is: the straight bar spring steel material is passed between the two symmetrical conveying wheels 4, and the lifting drive device 6 is used to make the lifting frame 5 with the upper conveying wheel 4 move down to the conical table 41 to adhere to the straight bar spring steel material, and the four conical tables 41 can be matched with different diameters of the straight bar spring steel material, and the conical table 41 does not need to be replaced when feeding the straight bar spring steel material with different diameters.

[0037] When the conveying wheel 4 is seriously worn, the positioning sleeve 22 can be manually slid towards the side away from the conveying wheel 4 until the positioning sleeve 22 is separated from the positioning boss 42, and at this time, the conveying wheel 4 can be removed; when the conveying wheel 4 is installed, the positioning sleeve 22 is manually slid towards the side away from the conveying wheel 4 until the auxiliary positioning groove 24 is completely located outside the positioning sleeve 22, at this time, the positioning boss 42 is inserted from any one of the two slots of the L-shaped auxiliary positioning groove 24, the positioning sleeve 22 is loosened, the positioning sleeve 22 is sleeved outside the positioning boss 42, and the positioning boss 42 is fixed relative to the fixing roller 21.
