Description

Technical Field

[0001] This utility model relates to the field of chain stabilization device technology, and in particular to an adjustable chain stabilization device for coating lines. Background Technology

[0002] In coating production lines, workpieces are typically transported via overhead or ground chains. Due to the weight of the chain itself, the weight of the workpiece it carries, and the span generated by long-distance transport, the chain commonly experiences sagging and shaking during operation. This shaking causes the workpiece to sway unsteadily, affecting the uniformity of the coating quality. In severe cases, it can even cause production accidents such as workpiece collisions or falling. At the same time, the severe shaking of the chain also accelerates its own wear and reduces the service life of the equipment.

[0003] In traditional chain stabilizing devices, the most common method is to support the chain with a bracket or roller with a fixed height. However, this method lacks adjustability and cannot adapt to load changes caused by workpieces of different models and weights. It also cannot compensate for the sagging of the chain caused by stretching after long-term use. The fixed support structure can only correspond to one working condition and has poor flexibility. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

Two guardrails are fixedly connected to the top of the frame. Two first rotating shafts are rotatably connected between the two guardrails. Two first sprockets are keyed to the outer sides of the two first rotating shafts. A chain is provided between the two first sprockets on the same side. Fixing blocks are fixedly connected to both sides of the frame. Threaded cylinders are rotatably connected to the top of the two fixing blocks.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-4 An adjustable coating line chain stabilizing device includes a frame 1. Two guardrails 3 are bolted to the top of the frame 1. Two first rotating shafts 12 are rotatably connected between the two guardrails 3. Two first sprockets 13 are keyed to the outer sides of the two first rotating shafts 12. A chain 5 is provided between the two first sprockets 13 on the same side. Fixing blocks 11 are bolted to both sides of the frame 1. Threaded cylinders 9 are rotatably connected to the top of each fixing block 11. Threaded rods 7 are threaded into each threaded cylinder 9. Connecting blocks 18 are fixedly connected to one end of each of the two threaded rods 7. Second rotating shafts 16 are fixedly connected to one side of each of the two connecting blocks 18. Two second sprockets 14 are rotatably connected to the outer sides of the two second rotating shafts 16, and the second sprockets 14 mesh with the chain 5. In use, the thread of the threaded rod 7 is a triangular thread with a tooth angle of 60°, which drives the threaded cylinder 9 to rotate. Due to the threaded engagement between the threaded cylinder 9 and the threaded rod 7, the threaded rod 7 moves up and down in the vertical direction. When the threaded rod 7 rises, the second rotating shaft 16 drives the second sprocket 14 to move upward, and the chain 5 is pulled upward. When the threaded rod 7 falls, the second sprocket 14 moves downward, and the tension of the chain 5 decreases, so as to realize the dynamic adjustment of the tension of the chain 5 to adapt to different workpiece loads and the stretching and sagging of the chain 5, and effectively suppress the vibration of the chain 5 during operation.

[0018] In this utility model, a motor 2 is fixed to the outside of the guardrail 3 by bolts, and one end of the output shaft of the motor 2 is connected to one of the first rotating shafts 12 through a coupling. A sliding groove 8 is provided on one side of both guardrails 3, and a slider 15 is slidably connected in both sliding grooves 8. One end of the second rotating shaft 16 passes through the slider 15. Multiple connecting rods 4 are provided between the two chains 5, and the two ends of the connecting rods 4 are respectively fixed to the chain link pins of the two chains 5. The connecting rods 4 connect the two chains 5 into a whole. When the chains 5 are running, the connecting rods 4 can balance the force on the two chains 5, reduce the conveying deviation caused by the shaking of a single chain 5, and ensure the stability of the coated workpiece during the conveying process. In use, the sliding of the slider 15 in the sliding groove 8 provides a stable guiding effect for the lifting and lowering of the second rotating shaft 16, and prevents the second sprocket 14 from deviating during the adjustment process.

[0019] In particular, a dust cover 6 is bolted to the top of the threaded cylinder 9, and the top of the dust cover 6 is conical. The conical top of the dust cover 6 can effectively guide dust and impurities falling on its surface to the edge and slide off, preventing them from entering the threaded cylinder 9 and affecting the thread fit. A handwheel 10 is welded to the bottom of the threaded cylinder 9 through the fixing block 11, and the outer side of the handwheel 10 is provided with anti-slip texture. The anti-slip texture on the outer side of the handwheel 10 increases the friction between the hand and the handwheel 10, preventing slippage when rotating. The outer side of the threaded rod 7 is provided with scale lines 17. By observing the scale lines 17 on the outer side of the threaded rod 7, the adjustment height of the second sprocket 14 can be precisely controlled to ensure that the tension of the chains 5 on both sides is consistent.

[0020] Working principle: When the motor 2 is started, the output shaft of the motor 2 drives the first rotating shaft 12 to rotate through the coupling. The first sprocket 13 on the outer side of the first rotating shaft 12 rotates accordingly, thereby driving the chain 5 to circulate between the two first sprockets 13. When it is necessary to adjust the tension of the chain 5, the operator turns the handwheel 10. The handwheel 10 drives the threaded cylinder 9 to rotate. Since the threaded cylinder 9 is threadedly engaged with the threaded rod 7, and the threaded rod 7 is connected to the slider 15 through the second rotating shaft 16, the slider 15 slides in the groove 8 to restrict the rotation of the threaded rod 7, so that the threaded rod 7 rises and falls in the vertical direction. When the threaded rod 7 rises, the second rotating shaft 16 drives the second sprocket 14 to move upward, and the chain 5 is tightened upward. When the threaded rod 7 falls, the second sprocket 14 moves downward, and the tension of the chain 5 decreases. This realizes the dynamic adjustment of the tension of the chain 5 to adapt to different workpiece loads and the stretching and sagging of the chain 5, effectively suppressing the vibration of the chain 5 during operation.

[0021] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
