A number of support cross bars 3 are evenly provided inside the platform frame 2 and along the width direction. A number of bearing seats 4 are symmetrically provided on both sides of the upper surface of the platform frame 2. The bearing seats 4 on both sides of the upper surface of the platform frame 2 correspond to each other one by one. The bearing seats 4 and the support cross bars 3 are arranged at intervals. A support foot 14 is provided at the bottom of the support frame 1 to achieve overall support.

[0024] There are several conveying rollers 5, each of which is provided with a positioning groove. The top of the support roller 11 matches the height of the upper part of the positioning groove to achieve cooperation with the corresponding workpiece. The conveying roller 5 is rotatably connected to the corresponding bearing seat 4 on both sides through the shaft 6. The conveying roller 5 is located on the same vertical plane. A double-row sprocket 7 is provided at one end of the shaft 6. Adjacent shafts 6 are connected to each other through the double-row sprocket 7 and the chain 8. A protective cover 15 is also provided on the upper surface of the platform frame 2. The double-row sprocket 7 and the chain 8 are both arranged in the protective cover 15. The protective cover is used to hide the double-row sprocket 7 and the chain 8, thereby ensuring production safety.

[0025] The drive mechanism includes a drive motor 9, which is mounted on the lower surface of the platform frame 2 through a motor seat, and the output shaft of the drive motor 9 is provided with a double row of sprockets 7 connected to the corresponding shaft rod 6 through a sprocket;

[0026] The support assembly corresponds one-to-one to the support cross bar 3. The support assembly includes a U-shaped frame 10, a support roller 11, a screw 12 and a positioning nut 13. The support roller 11 is provided on the inside of the U-shaped frame 10, and the screws 12 are symmetrically provided on both sides of the bottom of the U-shaped frame 10. The screws 12 pass through the corresponding support cross bar 3. Positioning nuts 13 are provided above and below the screw 12 on the support cross bar 3. The positions of the support roller 11 and the conveying roller 5 correspond to each other.

[0027] like Figure 4 As shown, the U-shaped frame 10 includes two side panels 1001 and a connecting plate 1002. The side panels 1001 are symmetrically arranged at both ends of the connecting plate 1002. The side panels 1001 are connected to the connecting plate 1002 by bolts. Screw holes are provided at the bottom of the side panels 1001 to cooperate with the screw rod 12 for connection. The U-shaped frame 10 of this structure facilitates the installation of the support roller 11, and the screw holes are used to achieve connection with the screw rod 12.

[0028] Installation method and operating principle: First, assemble the frame, wherein several support crossbars 3 are welded inside the platform frame 2. Connect the ends of the shaft rod 6 with the double-row sprocket 7 and the conveyor roller 5 to the bearings in the bearing seat 4 respectively, then put the chain 8 on the outside of the two adjacent shaft rods 6 respectively, and install the bearing seat 4 on both sides of the upper surface of the platform frame 2 with bolts, and then connect the chain 8 with the corresponding double-row sprocket 7 to complete the linkage of the two adjacent shaft rods 6. Install the drive motor 9 at the bottom of the platform frame 2 through the motor seat, and at the same time connect it to the sprocket on the output shaft of the drive motor 9 through the double-row sprocket 7 and chain 8 of the corresponding shaft rod 6. Then screw a positioning nut 13 on the screw rod 12, and pass the screw rod 12 through the corresponding support crossbar 3. After screwing another positioning nut 13, the top of the screw rod 12 is threadedly connected to the bottom of the side plate 1001 of the U-shaped frame 10 to complete the installation. During use, according to the corresponding workpiece, adjust the two positioning nuts 13 on the same screw 12 so that the top of the support roller 11 of the U-shaped frame 10 matches the top of the positioning groove of the conveying roller 5. When the workpiece is conveyed by the conveying roller 5, the end of the workpiece can be supported by the support roller 11 after passing the conveying roller 5, thereby avoiding the situation where the workpiece is stuck due to the large spacing between the conveying rollers 5. The utility model has a reasonable structure. Several supporting cross bars 3 are evenly arranged in the platform frame 2, and each supporting cross bar 3 is matched with a supporting assembly. Since the bearing seat 4 and the supporting cross bar 3 are arranged at intervals, the conveying roller 5 connected to the bearing seat 4 through the shaft 6 is arranged at intervals with the supporting assembly. When the workpiece is conveyed by the conveying roller 5, it can be supported by the support roller 11 of the supporting assembly after passing through a conveying roller 5, ensuring that the end of the workpiece does not sag during conveyance, causing the conveying to be hindered, and through the support of the support assembly, there is no need to reduce the distance between the two conveying rollers 5, so that the cost is reduced. At the same time, the support assembly can achieve height adjustment through the cooperation of the screw 12 and the positioning nut 13. When used for conveying different workpieces, only the matching conveying roller 5 needs to be replaced, and there is no need to replace the support assembly separately, which greatly improves convenience.

[0029] Anything not described in detail in the present invention is well known to those skilled in the art.

[0030] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
