Description

Technical Field

[0001] The utility model relates to the technical field of net-opening machines, in particular to a plastic braided belt net-opening machine. Background Art

[0002] Plastic woven belts are commonly used as raw materials for the production of bulk bags, snakeskin bags, etc., and are generally woven on circular looms. The production process of plastic woven belts is: first, a whole piece of plastic film is made, and then the plastic film is cut into the required width of the woven belt. Finally, the cut woven belt needs to be opened to soften the woven belt and meet the weaving requirements. At present, a net-opening machine is generally used to open the net of plastic woven belts. The core component of the net-opening machine is the needle-opening roller. The needle-opening roller consists of an axial roller and a number of mesh needles arranged on the axial roller. The mesh needles are arranged along the radial direction of the axial roller, and the axial roller and the mesh needles are an integrated structure. Plastic woven belts are generally fed into the mesh opening machine in parallel at equal intervals for mesh opening. Since the mesh needles on the needle roller are consumable parts, the parts of the needle roller where the woven belt passes are prone to wear, while the interval between two adjacent woven belts, that is, the parts of the needle roller that do not contact the woven belt, are not prone to wear. When the parts of the needle roller that are prone to wear cannot meet the mesh opening requirements, the entire needle roller must be replaced. The cost of replacing a set of needle rollers is high, and the machine needs to be shut down during replacement, affecting normal production.

[0003] In the Chinese patent with the publication number CN202540377U, the field of production machinery for plastic braided belts is disclosed, and in particular, it relates to a plastic braided belt opening machine, which has a needle roller, a motor for driving the needle roller to rotate, and brackets for supporting the needle roller respectively arranged at both ends of the needle roller, and also has an adjustment mechanism for adjusting the axial position of the needle roller, the adjustment mechanism includes a linear guide rail and a moving part for adjusting the position of the bracket, the two brackets are connected to the linear guide rail by sliding or rolling, one end of the moving part is connected to one of the brackets, and the other end is connected to the linear guide rail. The utility model plastic braided belt opening machine is provided with an adjustment mechanism, when the part of the needle roller that is easily worn cannot meet the opening requirement, the position of the needle roller can be adjusted, so that the contact position of the needle roller and the braided belt is transferred to the part that is not worn, so that the needle roller is fully utilized, the service life of the needle roller is extended, and resources are effectively saved, and the position of the needle roller is easy to adjust, the downtime is shortened, and the production efficiency is improved.

[0004] The prior art improves the utilization rate of the needle roller by changing the position of the needle roller. However, after the needle roller wear reaches a certain level, it is still replaced in a traditional way. For example, the Chinese patent with publication number CN 216435540 U, ​​a new type of PP filling rope net opening machine, relates to the filling material related technical field. The utility model includes a bottom plate, a roller sleeve, a clamping sleeve, a second connecting disk and a pressure roller. A second connecting disk is arranged on one side of the upper front part of the bottom plate. The clamping sleeve is fixed to the second connecting disk through the first connecting disk connected by a rotating column. A fixed disk is fixed to the end face of the roller away from the clamping sleeve. A roller sleeve is movably connected to the roller between the fixed disk and the clamping sleeve. Both ends of the pressure roller are rotatably connected to a connecting strip. The top of the connecting strip is rotatably connected to a threaded column. The upper part of the threaded column is threadedly connected to a side connecting plate. The utility model solves the problems that the existing PP filling rope opening machine cannot adjust the conveying angle of the PP filling rope and the needle roller is troublesome to replace and the replacement cost is high by arranging a bottom plate, a roller sleeve, a clamping sleeve, a second connecting disk and a pressure roller, so that the conveying angle of the PP filling rope is more convenient to replace, the length of the opening net is more convenient to change, the needle roller can be replaced faster, and the cost is lower.

[0005] The prior art reduces the replacement time and cost of the needle roller by replacing the entire needle roller. However, this method is not convenient for fully using the needle roller that has not been worn out. Utility Model Content
