Description

Technical Field

[0001] This utility model provides a special pulley rotation tool for replacing V-belts in a vibrating feeder, which is used to replace damaged V-belts in a vibrating feeder, thus solving the problems of time-consuming and labor-intensive V-belt replacement process and the need for a large number of tools. Background Technology

[0002] The vibratory motor and eccentric block of the vibratory feeder are driven by a V-belt. Over time, the belt core is prone to wear, cracks, and even breakage, requiring frequent replacement. Currently, commonly used tools include an I-beam and two 10mm diameter bolts. To ensure even force distribution on the pulleys and V-belts, all three V-belts need to be replaced simultaneously. The new V-belt should be installed with the side closest to the motor as the inner side. The installation sequence is usually inner, middle, and outer. First, insert the lower part of the V-belt into the inner groove of the large pulley. Use the tool to hold the upper part of the V-belt in place. Insert the two 10mm bolts into the pulley holes of the large pulley. Use the I-beam and bolts to rotate the large pulley until the V-belt is fully inserted into the pulley groove and runs smoothly.

[0003] Existing tools can replace V-belts, but they suffer from uneven force on the large pulley, time-consuming and labor-intensive replacement processes, and the inconvenience of carrying multiple tools for alternating operations. Therefore, there is an urgent need for a new type of pulley rotation tool that is reasonably designed, time-saving and labor-saving to operate, and easy to carry. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple and practical tool for rotating pulleys to replace the V-belts of a vibrating feeder.

[0005] To achieve the above-mentioned objectives, this utility model employs the following technical solution:

[0006] A special rotating tool for replacing V-belt pulleys in a vibrating feeder includes four parts: a holding rod, a connecting rod, a trilobal working end, and an extension rod. The holding rod is a 500mm diameter circular steel pipe; the connecting rod is a circular steel pipe with one end welded to the middle of the holding rod and the other end welded to the center of the trilobal working end; the trilobal working end has through holes corresponding to three 11mm holes on the large pulley; the extension rod is a 40mm long, 10mm diameter high-strength bolt, with the bolt head annularly welded to the through hole on the trilobal working end to ensure sufficient strength and rigidity when rotating the pulley. Furthermore, the upper weld facilitates cutting and replacement should the bolt deform or become damaged.

[0007] The trilobed working end of the pulley rotary tool is a significant improvement, allowing for better matching between the tool and the large pulley. Under the same resultant force applied at the gripping end, it generates greater torque while ensuring the tool's rotation center coincides with the pulley's center, resulting in more balanced force distribution on the pulley. Changing V-belts is now faster and easier for operators, further reducing the number of tools needed and greatly facilitating maintenance work. Attached Figure Description

[0011] To better understand the technical solution of this utility model, the embodiments provided by this utility model are described in detail below with reference to the accompanying drawings.

[0012] This utility model embodiment provides a special pulley rotating tool for replacing V-belts in a vibrating feeder. For ease of operation, the side closest to the motor is designated as the inner V-belt. The installation sequence of the three V-belts is typically inner, middle, and outer V-belts. First, insert one V-belt into the inner groove of the large pulley. Use the tool to hold the V-belt in place through the groove of the small pulley. Insert the extension rod of the pulley rotating tool into the three 11mm holes of the large pulley. Rotate the upper handle of the tool clockwise to allow the V-belt to enter the groove of the small pulley. The installation steps for the middle and outer V-belts are basically the same as for the inner V-belt. It should be noted that the middle V-belt, when inserted into the middle groove of the large pulley from the outside, needs to pass through the outer groove of the small pulley before entering the middle groove. After each V-belt is installed, rotate the large pulley to observe whether the rotation is smooth. If any abnormality is found, remove and reinstall. After replacing all three V-belts, rotate the large pulley again to observe the operation of the V-belts. Once you confirm that the V-belts are fully engaged with the pulley grooves and that both pulleys are running smoothly, the replacement of the V-belts on the vibrating feeder is complete.
