Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to film blowing machine equipment for producing PLA biodegradable mulch films. Background Art

[0002] In order to ensure that the plants have a good living environment, the existing vegetable and crop planting needs to be covered with mulch. By using PLA biodegradable mulch, the plants can be directly oxidized, digested and absorbed by microorganisms, and converted into carbon dioxide, water and humus, and integrated into the soil. When producing biodegradable mulch, a film blowing machine is required. After the material is stirred, it is heated by the screw and barrel, and then injected into the bottom of the mold. The film is made into a cylinder by blowing, and finally it is stretched to the required thickness. Finally, a separate winding device is used to wind up the mulch to achieve the production of the mulch.

[0003] In the prior art, when in use, the existing mulching machine needs to adopt multiple sets of supporting guide roller structures to assist in stretching the mulching film, but the existing supporting guide rollers cannot be adjusted according to the width of the mulching film, resulting in the inability to adapt to different needs.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model is equipped with an adjustment support assembly, and the adjustment knob can be used to drive the adjustment screws at both ends to rotate. During the rotation, the two sets of sliding baffles can be controlled to adjust the position. After adjustment, it can adapt to different needs. The adjustment knob is located in the opening area on one side of the limiting guide roller, which is convenient for controlling the internal adjustment screw to rotate and adjust. The adjustment support assembly can be used to control the limiting structure for adjustment, thereby achieving adjustment to meet different needs.

[0016] Secondly, the utility model is equipped with an adjustment and calibration component. When the existing ground film is rolled up, it is necessary to ensure that the rolling position is centered. In order to ensure the centering, a calibration component needs to be set up and used for calibration. However, due to the vibration of the equipment, a sliding structure directly using the sliding structure is prone to deviation and cannot effectively limit the position. By setting a sliding block, an installation position can be provided for the inner structure, and the extrusion block can control the two sets of drive plates for adjustment through the internal pushing bracket. When the driving plate moves, it will pull the clamping blocks at both ends to contract. Under the support of the spring sheet, the clamping block will be squeezed on the outside of the limit slide rod for limitation, thereby maintaining the stability of the sliding block and avoiding the problem of sliding deviation affecting calibration due to vibration.
