Description

Technical Field

[0001] This utility model relates to the field of transformer winding technology, and in particular to a movable rotating reel. Background Technology

[0002] In transformer winding production, the limitations of traditional reels are becoming increasingly apparent. On one hand, their fixed specifications prevent them from flexibly adapting to different sizes of reels. Frequent reel replacements lead to low production efficiency and increased costs when facing diverse transformer winding needs. On the other hand, the poor linkage between traditional reels and the winding machine results in uneven tension during cable unwinding, severely impacting winding quality. Furthermore, the lack of real-time monitoring of cable usage makes product quota verification difficult, easily leading to raw material waste or shortages, and hindering quality traceability and process optimization.

[0003] Therefore, there is an urgent need for a rotating reel to solve the problems in the existing technology. Utility Model Content

Detailed Implementation

[0030] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] refer to Figure 1 A mobile rotating reel includes a trolley 1, a winding reel 2, and a guide assembly 3; the winding reel 2 is mounted on the trolley 1. (See also...) Figure 3 The winding reel 2 includes a base plate 2.1, a fixing rod 2.2, a turntable 2.3, a damping block 2.4, and a force sensor 2.5; the force sensor 2.5 is a ring-type force sensor. The base plate 2.1 is mounted on the handcart 1, and the fixing rod 2.2 is mounted on the base plate 2.1. The turntable 2.3 is rotatably mounted on the fixing rod 2.2. The damping block 2.4 is mounted on the base plate 2.1 and abuts against the turntable 2.3. The base plate has a 50mm×30mm groove to hold the spring-loaded rubber damping block. Since heavier cables have greater inertia and are more difficult to stop after being pulled by the winding machine, the spring-loaded damping block can provide greater friction when the cable above is heavier, thus allowing the reel to stop rotating more quickly.

[0032] The force sensor 2.5 is disposed between the base plate 2.1 and the trolley 1 to measure the weight of the cable wound on the turntable 2.3; the guide assembly 3 is disposed on the trolley 1 to guide the cable.

[0033] The base plate and turntable are made of carbon steel.

[0034] See Figure 1 and Figure 2 The guide assembly 3 includes a guide wheel fixing rod 3.1, a rotating shaft 3.2, and a guide wheel 3.3. The guide wheel fixing rod 3.1 has a rotating shaft 3.2, and the rotating shaft 3.2 has a rotatable guide wheel 3.3. Each of the guide wheel fixing rod 3.1, rotating shaft 3.2, and guide wheel 3.3 has two sets, and the two sets of guide wheels 3.3 are used to clamp and rotate the conveying cable. The rotating shaft 3.2 is a double-ended screw, and both ends of the double-ended screw are fixed to the two sets of guide wheel fixing rods 3.1 by nuts 3.7. The guide wheel 3.3 is rotatably mounted on the rotating shaft 3.2 via a deep groove ball bearing 3.4. The rotating shaft 3.2 also has a limiting assembly 3.5 that limits the movement of the deep groove ball bearing 3.4 along its length. The guide wheel fixing rod 3.1 has multiple mounting holes 3.6 spaced apart for mounting the rotating shaft 3.2 to different heights.

[0035] Two guide wheel fixing rods are welded to the handcart. A 10mm inner diameter hole is drilled every 50mm on each guide wheel fixing rod to facilitate adjustment of the M10 double-ended screw for guiding cables to reels of different heights. The double-ended screw is secured on both sides with M10-N type hexagonal nuts. The guide wheels are then inserted into deep groove ball bearings 16001 through slots at both ends to facilitate sliding and rotation on the double-ended screw. A limiting component is welded to the inner ring of the deep groove ball bearing 16001 to prevent misalignment of the two guide wheels from affecting the cable guiding function.

[0036] See Figure 4 The turntable 2.3 is rotatably mounted on the fixed rod 2.2 via a thrust ball bearing 2.6. The thrust ball bearing 51113 is welded into the slot of the turntable and can rotate relative to the base plate.

[0037] A damping plate 2.7 is also provided between the thrust ball bearing 2.6 and the turntable 2.3; the damping plate 2.7 is made of rubber. A flexible connection is established through the damping plate. Because the annular force sensor is a relatively precise sensor element, the damping plate is made of rubber to provide shock absorption and anti-impact for the annular force sensor below, preventing excessively heavy cable reels from instantly damaging the annular force sensor. The annular force sensor can measure changes in the weight of the cable on the reel, facilitating the acquisition of cable quotas and enabling digital production.

[0038] The fixing rod 2.2 is detachably connected to the base plate 2.1 via a threaded connection. Since the reel is a heavy object and has no lifting holes, it needs to be lifted and aligned manually before the fixing rod is inserted. To reduce manual handling, the welded fixing rod has been replaced with a detachable design where the reel is placed first and then fixed with threads, thereby improving the speed of loading the reel. The fixing rod can also be rotated to different lengths depending on the height of the reel.

[0039] The trolley is also equipped with a digital panel that is electrically connected to the force sensor. The digital panel is used to display the measured value of the force sensor. The digital panel is mounted on the baffle of the trolley by a fixing bracket. The four corners of the fixing bracket are made of soft rubber to protect the 4004 digital panel. The digital panel is installed facing upwards for easy viewing of weight data. The connecting cable is laid along the edge of the trolley and connects to the output interface of the ring-shaped force sensor below the winding reel, displaying the electrical signal of the ring-shaped force sensor on the digital panel.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model within the spirit and principles of the present utility model.
