Description

Technical Field

[0001] The utility model relates to the technical field of cement paper bags, in particular to a novel cement paper bag tensioning device. Background Art

[0002] The bag making machine is a machine used to make cement paper bags or other material bags. Its processing range is plastic or other material bags of various sizes, thicknesses and specifications. The packaging belt of the bag making machine needs to be tensioned during use to facilitate subsequent operations. Tensioning rollers are conventionally used to achieve tensioning.

[0003] For example, the patent document with application number CN202220306147.3 discloses an adjustable tensioning device and a bag making machine for a bag making machine. The utility model can change the pressure applied to the material belt by the tensioning roller by installing a counterweight on the tensioning roller or removing the counterweight from the tensioning roller, thereby adjusting the tensioning force, thereby avoiding insufficient or excessive tensioning of the packaging belt. However, the adjustable tensioning device and the bag making machine cannot adjust the tension during use. If the cement paper bag is pulled too hard during the processing and conveying process, it may cause the cement paper bag to rupture, affecting its normal use in the later stage.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a new cement paper bag tensioning device is proposed. Utility Model Content

[0007] Furthermore, a second tensioning roller is provided at the bottom of the first tensioning roller, and the overall structure of the second tensioning roller is consistent with the overall structure of the first tensioning roller.

[0008] Furthermore, mounting blocks are vertically arranged at the four corners of the frame, and fixing screws are inserted through the middle of the mounting blocks.

[0009] Furthermore, a cover plate is fixedly mounted on the front end of the frame, and the cover plate is parallel to the frame.

[0010] Furthermore, a groove is provided on the cover plate at a position corresponding to the material roller, and a control panel is fixedly installed on the upper middle part of the cover plate, and the control panel is electrically connected to the pressure sensor.

[0011] Furthermore, a bearing seat is slidably provided on the outer wall of the end of the first tensioning roller, and a hydraulic rod is fixedly installed on the end of the first tensioning roller.

[0012] Compared with the prior art, the utility model has the beneficial effect that the novel cement paper bag tensioning device can not only prevent the material belt from breaking during the tensioning process, but also can adjust the length of the tensioning roller so that it can be used for material belts of different widths.

[0013] 1. The utility model sets a detection component so that the material belt lifts the roller set inside the shell during the movement and tensioning process, and the rising roller lifts the top plate set on the top of the support rod, and applies pressure to the pressure sensor, so that the pressure sensor transmits the tightness value of the material belt during the movement to the control panel, so that the staff can intuitively see the tension of the material belt, thereby achieving the purpose of preventing the material belt from breaking during the tensioning process;

[0014] 2. The utility model uses a hydraulic rod in conjunction with the bearing seat to control the first tensioning roller to move between the bearing seats and adjust the reserved length between the first tensioning roller and the bearing seat, so that the first tensioning roller can be used for material strips of different widths, thereby improving ease of use.
