Description

Technical Field

[0001] This utility model relates to an auxiliary feeding device for profile processing. Background Technology

[0002] The original profile processing (such as drilling, grooving, and cutting) required two people working together, using a crane to flip and turn the profiles. Because each workpiece was heavy and long, manual pushing and pulling for feeding resulted in low efficiency, high labor intensity, and significant safety risks.

[0003] Chinese utility model patent CN218815312U, authorized on April 7, 2023, discloses an integrated unloading platform. It includes a conveyor roller assembly, a base, an elastic support assembly, and a limiting assembly. The elastic support assembly is vertically arranged, with its top end connected to the bottom of the conveyor roller assembly and its bottom end connected to the top of the base. Two sets of limiting assemblies are symmetrically arranged axially about the conveyor roller assembly. Each limiting assembly includes a baffle, a fixed seat, a sliding rod, a rotating platform, and a support base. The bottom of the baffle is rotatably connected to the conveyor roller assembly, and the baffle gradually slopes outwards from bottom to top. The fixed seat is mounted on the baffle, and the sliding rod is mounted on the fixed seat. The rotating platform has a through hole for the sliding rod to pass through, and the rotating platform is rotatably mounted on top of the support base, which is mounted on the base. This integrated unloading platform can limit the conveying range to prevent materials from falling from the side, thus ensuring the safety of the unloading process.

[0004] The integrated unloading platform has a complex structure. The unloading platform cannot rotate, and after a long period of use, the bearings inside its rollers are prone to damage or lack of lubrication. If the rollers are not replaced or repaired in time, improper wear at the ends of the roller shafts can easily occur.

[0005] There is an urgent need for a simple, easy-to-disassemble, easy-to-maintain, and rotatable auxiliary feeding device for profile processing. Summary of the Invention

[0006] The technical problem to be solved by this utility model is how to overcome the defects of the prior art and provide a profile processing auxiliary feeding device that is simple in structure, easy to disassemble, assemble and repair, and rotatable.

[0007] To solve the above-mentioned technical problems, this profile processing auxiliary feeding device includes a base and a roller frame. The roller frame is installed on the base and N rollers are arranged on the roller frame. The base includes a bottom frame and columns welded to the bottom frame. The roller frame includes a crossbeam and two opposing channel steels welded to both ends of the crossbeam. The middle section of the crossbeam is rotatably fixed to the columns. N opposing vertical slots are respectively opened on the two channel steels. Each vertical slot is formed by vertical cuts made on the inner side and side wall of the top plate of the channel steel. Each roller includes a roller cylinder. The roller shaft and two end bearing seats are provided with bearings, which are respectively set at both ends of the roller. The roller shaft passes through the roller and the bearing seats and bearings at both ends. The diameter of the roller shaft at both ends is greater than the width of the vertical slot. Vertical planes are ground and cut on both sides of the roller shaft. The distance between the two vertical planes is less than or equal to the width of the vertical slot. There are slots below each vertical plane. The part with the vertical plane at both ends of each roller shaft is inserted into the corresponding vertical slot. The slots are respectively locked on the side wall of the channel steel at the root of the vertical slot. N is a positive integer and 2≤N≤6.

[0008] The two vertical planes at both ends of the roller shaft form a locking part that matches the vertical slot. By using this locking part to lock into the vertical slot, the roller shaft is fixed simply and effectively, preventing improper rotation of the roller shaft. Furthermore, the locking points are respectively locked onto the channel steel sidewall at the root of the vertical slot, which can effectively prevent the idler roller from moving left and right.

[0009] This design utilizes channel steel to create the roller frame, with vertical slots cut into it. Two vertical flat slots are made at each end of the roller shaft, and then each roller is simply and firmly fixed to the roller frame. The design is secure, easy to assemble and disassemble, and easy to lubricate. Furthermore, if the bearings at both ends of the roller are damaged, they can be replaced promptly.

[0010] As an optimization, a short pipe is welded to the lower part of the middle section of the crossbeam, and this short pipe can be rotatably fitted onto the column. This design results in a simple structure and convenient processing.

[0011] This utility model of auxiliary feeding device for profile processing has a simple structure, is easy to use, and is easy to assemble and disassemble, making it suitable for auxiliary feeding in profile processing. Attached Figure Description
