Description

Technical Field

[0001] The utility model relates to the field of belt tensioning, in particular to a novel belt tensioning mechanism for a paraffin molding machine. Background Art

[0002] In industrial equipment such as paraffin molding machines, belts often undertake important functions such as material transportation and power transmission. However, current belt tensioning mechanisms usually require manual adjustment, such as changing the position of the tensioner pulley using fasteners such as bolts and nuts. This adjustment method is not only time-consuming and labor-intensive, but also difficult to accurately control the tightness of the belt. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a novel belt tensioning mechanism for a paraffin wax molding machine.

[0004] The technical solution adopted by this utility model:

[0005] The top of the front side wall of the movable plate is fixedly connected to the rotating shaft one, and the outer wall of the rotating shaft is rotatably connected to the tension wheel, and the left and right sides of the top of the front side wall of the fixed plate are fixedly connected to the rotating shaft two, and the outer wall of the rotating shaft two is rotatably connected to the fixed wheel.

[0006] The belt goes around the top of the outer wall of one of the fixed wheels, goes down and goes around the bottom of the outer wall of the tensioning wheel, and then goes around the top of the outer wall of the other fixed wheel.

[0007] Beneficial effects of the utility model:

[0008] The utility model can accurately adjust the upper and lower positions of the tensioner pulley by rotating the lead screw, thereby realizing accurate control of the belt tightness. The tension can be adjusted by simply rotating the rotating rod, and the operation is simple and convenient.

[0009] The design of the locking nut can ensure that the screw will not loosen after adjustment, keep the position of the tensioner stable, and thus ensure the continuous tension of the belt. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] like Figure 1-5 As shown: A new belt tensioning mechanism for a paraffin molding machine includes a fixed plate 1, a fixed groove 2 is provided on the front side wall of the fixed plate 1, the upper part of the fixed groove 2 is through, the left and right inner side walls of the fixed groove 2 are fixedly connected to the slide bar 3, the slide bar 3 extends up and down, and a movable plate 4 is provided in the fixed groove 2, the movable plate 4 slides with the fixed groove 2, and the left and right side walls of the movable plate 4 are provided with a slide groove 5, the slide groove 5 slides and engages with the slide bar 3, the middle part of the top of the front side wall of the movable plate 4 is fixedly connected to the fixed seat 6, the top of the fixed seat 6 is rotatably connected to the bottom of the screw 7, and the screw 7 moves upward It extends vertically, and the top of the screw 7 is fixedly connected to the rotating rod 8. The middle part of the top of the fixing groove 2 is fixedly connected to the connecting seat 9 by a bolt 10. The screw 7 passes through the connecting seat 9. The screw 7 is threadedly matched with the connecting seat 9. The outer wall of the screw 7 is threadedly sleeved with the locking nut 11, and the bottom of the locking nut 11 is tightly pressed against the top of the connecting seat 9. The middle part of the front side wall of the movable plate 4 is fixedly connected to the rotating shaft 12, and the outer wall of the rotating shaft 12 is rotatably connected to the tensioning wheel 13. The left and right sides of the top of the front side wall of the fixed plate 1 are fixedly connected to the rotating shaft 2 14, and the outer wall of the rotating shaft 2 14 is rotatably connected to the fixed wheel 15.

[0017] The belt 16 passes around the top of the outer wall of one of the fixed pulleys 15 , passes around the bottom of the outer wall of the tensioning pulley 13 downward, and then passes around the top of the outer wall of the other fixed pulley 15 .

[0018] The belt 16 passes around the tops of the two fixed pulleys 15 and the bottom of the tensioner 13 . Initially, the position of the tensioner 13 may not be optimal, resulting in inappropriate tightness of the belt 16 .

[0019] The operator rotates the rotating rod 8, which drives the screw 7 to rotate. Since the screw 7 is threadedly engaged with the connecting seat 9, the rotation of the screw 7 is converted into linear motion, that is, the screw 7 moves up or down.

[0020] When the lead screw 7 moves downward, it pushes the movable plate 4 to slide downward along the slide bar 3 . The sliding of the movable plate 4 drives the tensioner 13 to move downward, thereby tightening the belt 16 .

[0021] On the contrary, if the belt 16 is too tight, the screw 7 can be moved upward by rotating the rotating rod 8, thereby driving the tensioning wheel 13 to move upward and loosening the belt 16.

[0022] When the tensioner 13 is adjusted to the appropriate position and the tightness of the belt 16 reaches the required level, the operator tightens the locking nut 11 downward along the screw 7 so that its bottom is against the top of the connecting seat 9. This prevents the screw 7 from loosening due to vibration or other external forces, and keeps the position of the tensioner 13 stable.
