Description

Technical Field

[0001] The utility model relates to a conveyor belt of a paper bag machine, in particular to a conveyor belt of a paper bag machine with an adjustable output position. Background Art

[0002] The Chinese invention application with the publication number CN112976106A discloses a variable cutting and conveying structure for the handle rope distance of a paper bag machine, including a rear conveying mechanism for conveying the finished handle. Since the finished handle needs to be attached to the paper bag, the finished handle output by the rear conveying mechanism needs to fall onto the subsequent conveying mechanism for turning. When the handle rope distance changes, it is necessary to adjust the output position of the finished handle of the rear conveying mechanism to ensure that it falls in place. To adjust the tension of the rear conveyor belt, a pressure wheel is used for lifting compensation, and the compensation range is small, thus restricting the adjustment of the output position of the rear conveying mechanism. Content of the Utility Model

[0003] In view of the technical problems existing in the background art, the utility model aims to provide a conveyor belt of a paper bag machine with an adjustable output position, moving an adjusting pulley to adjust the output position of the conveyor belt, and rotating a rotating member to adjust the tightness of the conveyor belt.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: The conveyor belt of the paper bag machine with an adjustable conveying length includes a pulley set and a conveyor belt. The conveyor belt is wound around the pulley set, and the conveyor belt is equipped with a tension control component. Among them, the pulley set includes an adjusting pulley, and the adjusting pulley is movably adjusted. The tension control component includes a rotating member, and the rotating member is rotatably arranged. The rotating member is provided with a first pulley and a second pulley. The first pulley is located inside the enclosure formed by the conveyor belt, and the second pulley is located outside the enclosure formed by the conveyor belt.

[0005] In this solution, the adjusting pulley corresponds to the output position. Moving the adjusting pulley can change the output position of the conveyor belt. Rotating the rotating member causes the first pulley and / or the second pulley to move. Since the conveyor belt is located between the first pulley and the second pulley, rotating the rotating member can wind the conveyor belt around the first pulley and / or the second pulley to adjust the tightness, and the adjustment range is large.

[0006] Preferably, the first pulley and the second pulley are arranged around the rotation center of the rotating member.

[0007] In this solution, rotating the rotating member winds the conveyor belt around the first pulley and the second pulley. The adjustment range for one rotation of the rotating member is close to the circumferences of the two pulleys, and the adjustment range is large.

[0008] Preferably, the rotating member is engaged with an adjusting gear, and the adjusting gear is connected to an adjusting shaft.

[0009] In this solution, the rotation adjustment shaft drives the rotating member through the adjustment gear, enabling accurate control of the tension.

[0010] Preferably, the conveyor belt is equipped with a conveying pressure belt, the conveying pressure belt passes around the adjustment pressure belt pulley, the adjustment pressure belt pulley is movably adjusted, and the adjustment pressure belt pulley cooperates with the adjustment belt pulley.

[0011] In this solution, the conveying pressure belt cooperates with the conveyor belt to press and convey the finished handle, preventing the finished handle from shifting. The adjustment pressure belt pulley cooperates with the adjustment belt pulley to ensure the close cooperation between the conveying pressure belt and the conveyor belt.

[0012] Preferably, the adjustment belt pulley is connected to a swing rod, the swing rod is connected to a rotating shaft, and the rotating shaft is rotatably arranged.

[0013] In this solution, the rotation of the rotating shaft drives the swing rod to swing around the axis of the rotating shaft, thereby changing the position of the adjustment belt pulley and the output position.

[0014] Preferably, the swing rod is movably adjusted along the radial direction of the rotating shaft.

[0015] In this solution, the swing rod is movably adjusted along the radial direction of the rotating shaft, enabling fine adjustment on the basis of swinging.

[0016] The beneficial effect of the present utility model is that the rotation of the rotating member can wind the conveyor belt around the first pulley and / or the second pulley, with a large adjustment range. Therefore, the present utility model has substantial features and progress compared with the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
