Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation processing, in particular to a wrapping film paper tube cutting machine. Background Art

[0002] Paper tube cutting machines are widely used in the packaging material manufacturing industry, particularly in the production of stretch film, where paper tubes are a crucial carrier. As market demand for stretch film diversifies, various specifications of stretch film are becoming increasingly mainstream. To meet this demand, paper tube cutting machines must be highly efficient and flexible, capable of cutting a wide range of paper tubes in a short time, thereby improving production efficiency and product quality.

[0003] Currently, the most common paper tube cutting machines on the market primarily use a fixed cutting method, where the cutting blade is fixed in position and can only cut paper tubes to a specific length. While this fixed cutting method is simple to operate, it has significant limitations in practice. To meet the demand for paper tubes of varying specifications, some companies have adopted a combination of multiple machines, each responsible for cutting paper tubes of different lengths.

[0004] However, none of the above methods can effectively solve the problem of flexibility in cutting the paper tube length. Therefore, how to design a paper tube cutting machine that can flexibly adjust the cutting length to meet the production needs of paper tubes of different specifications has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The present application provides a stretch film paper tube cutting machine, which is convenient for cutting paper tubes of different sizes.

[0006] The present application provides a stretch film paper tube cutting machine, which adopts the following technical solutions:

[0007] A wrapping film paper tube cutting machine includes a feeding platform, which includes multiple platforms. The paper tube is transported to the cutting equipment by mutual transportation of the multiple platforms. A first pushing cylinder is provided on one side of the feeding platform, and a bearing is provided on the side of the feeding platform away from the first pushing cylinder. The first pushing cylinder is used to push the paper tube to be sleeved on the bearing for cutting. Multiple cutting components are provided above the bearing, and the cutting components cut different positions of the paper tube respectively. A pushing member is slidably connected to the bearing, and a limiting platform is provided on one side of the feeding platform. The pushing member pushes the cut paper tube into the limiting platform for collection.

[0008] By adopting the above technical solution, the utility model designs a wrapping film paper tube cutting machine. When in use, the paper tube is placed on the feeding platform, and after multiple conveyances, the paper tube is sleeved on the bearing by using the first pushing cylinder, and the paper tube is cut by using the cutting components at different positions above the bearing. This cutting method can make the cut paper tubes of different sizes, and the size to be cut is determined according to needs.

[0013] Preferably, a baffle is provided between the fourth platform and the fifth platform, a lifting cylinder is provided at the bottom of the baffle, and an output shaft of the lifting cylinder is fixedly connected to the bottom of the baffle.

[0014] By adopting the above technical solution, when in use, the baffle between the fourth platform and the fifth platform can effectively control the transmission process of the paper tube. After the paper tube is transported to the fourth platform, the baffle is first raised to block it, and then the baffle is lowered. When the paper tube falls into the gap in the baffle, the baffle is raised to lift the paper tube and enter the fifth platform.

[0015] Preferably, a limiting roller is further provided on one side of the bearing, and the limiting roller is used to limit the paper tube on the bearing.

[0019] Preferably, the cutting assembly includes a fixed rod arranged on one side of the bearing and a cutter arranged on the fixed rod, the cutter is fixed to the fixed rod through a mounting bracket, and a servo motor for driving the cutter is also provided on the fixed rod.

[0020] By adopting this technical solution, the cutting assembly can achieve precise cutting at different locations on the paper roll during use, ensuring cutting quality. The cutter is fixed to the fixed rod via a mounting bracket, improving the cutter's stability and durability. The use of a servo motor allows the cutter to precisely control cutting speed and force, further improving cutting accuracy and efficiency.

[0021] Preferably, the limiting platform includes a side plate and a movable plate, the side plate and the movable plate are cooperatively connected, and a second flip cylinder is provided at one end of the movable plate, and the second flip cylinder is used to drive the movable plate to flip, thereby flipping the paper tube located on the limiting platform to the next platform.

[0022] By adopting the above technical solution, during use, the coordinated connection between the side panels and the movable panel ensures the position accuracy and stability of the paper tube when it enters the limit platform, while the setting of the second flipping cylinder realizes the automated flipping action, smoothly transferring the paper tube to the next platform, thereby improving production efficiency and safety.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. This utility model designs a wrapping film paper tube cutting machine. The mutual conveying of multiple platforms and the coordinated use of the first push cylinder ensure the stability and accurate positioning of the paper tube before entering the cutting station, avoiding the problems of paper tube deviation or deformation in the traditional single-platform conveying method, and improving the cutting quality and yield rate.

[0025] 2. This utility model is designed to cut a wrapping film paper tube. Multiple cutting components are installed above the bearing to cut different positions of the paper tube at the same time, which significantly improves the cutting speed and accuracy, and meets the high efficiency requirements of the production of paper tubes of different sizes.
