Description

Technical Field

[0001] This utility model belongs to the field of life jacket production technology, specifically relating to a rolling and cutting device for life jacket production. Background Technology

[0002] Life jackets are a crucial piece of water safety equipment, primarily used to prevent drowning and provide buoyancy support for those who fall into the water. Life jackets are made of nylon or neoprene fabric and filled with buoyancy materials such as polyethylene foam. They provide stable buoyancy, require no maintenance, and are suitable for long-term water operations.

[0003] Currently, in the production of life jackets, roll-cutting equipment is used to cut rolls of wide reflective fabric. Most existing roll-cutting equipment requires pulling the wide reflective fabric to move it and cutting it into strips during the winding process. However, the equipment for rolling and cutting wide reflective fabric requires lifting it high, aligning it, and then fitting it onto the outside of the shaft column to drive its rotation. The feeding structure is complex and the operation is cumbersome. Therefore, a roll-cutting device for life jacket production is proposed. The roll of wide reflective fabric is placed on two rubber drive shafts. A geared motor drives the rubber drive shafts to rotate the roll of wide reflective fabric. The feeding is simple, and the drive component drives the cutting component to move down to roll and cut the wide reflective fabric. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a rolling and cutting device for the production of life jackets. The rolled wide reflective fabric is placed on two rubber drive shafts, and the geared motor drives the rubber drive shafts to rotate the rolled wide reflective fabric. The feeding is simple, and the drive component drives the cutting component to move down to roll and cut the rolled wide reflective fabric.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0006] A rolling and cutting device for life jacket production includes a base and a second pulley. Rubber drive shafts are rotatably connected to the top two ends of the base via bearings. A protective cover is fixed to one end of the base by bolts. A geared motor is mounted on one side of the protective cover via a mounting bracket. A base frame is fixed to one side of the base by bolts. Horizontal columns are fixed to both ends of the base frame by bolts. A drive assembly is provided on the top of the horizontal columns.

[0007] The drive assembly includes a structural frame mounted on the top of the cross column. A servo motor is mounted on the top of the structural frame via a mounting bracket. A lead screw is rotatably connected inside the structural frame via a bearing. An internally threaded slider is sleeved on the outside of the lead screw. A cutting assembly is located on one side of the internally threaded slider. The cutting assembly includes a protective shell. A drive motor is mounted on the top of the protective shell via a mounting bracket. A cutting blade is rotatably connected inside the protective shell via a bearing.

[0008] By adopting the above technical solution, the geared motor drives the rubber transmission shaft to rotate, which in turn drives the roll of wide reflective fabric on the two rubber transmission shafts to rotate. The servo motor drives the lead screw to rotate, which pushes the protective shell down through the internal threaded slider. The drive motor drives the cutting blade to rotate and cut the roll of wide reflective fabric.

[0009] Specifically, the rubber drive shaft inside the protective cover has a first gear fixedly mounted on one end via a flat key, and the output shaft of the geared motor inside the protective cover has a second gear fixedly mounted on it via a flat key. The second gear meshes with the first gear.

[0010] Based on the above scheme and as a preferred option: the bottom ends of the structural frame are connected by sliding sleeves, the sliding sleeves are fitted on the outside of the horizontal column, the top ends of the fixing bolts are connected to fixing bolts through threaded grooves, and the top of the horizontal column is provided with corresponding locking holes at equal intervals.

[0011] Based on the above scheme and as a preferred option: the bottom output shaft of the servo motor is fixedly connected to the top of the lead screw through a connecting sleeve, and the structural frame is located inside the lead screw on one side and is fixed with a vertical rod by bolts, with the vertical rod passing through the internal threaded slider.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: an arc-shaped groove is provided at the bottom of the protective shell, and the rotating shaft of the cutting blade located on the outside of the protective shell is fixedly fitted with a second pulley by a flat key.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: a pulley is fixedly mounted on one side of the output shaft of the drive motor via a flat key, and a belt is mounted on the outer side of the pulley and the second pulley.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This utility model discloses a rolling and cutting device for life jacket production. Compared with the prior art, it places a roll of wide reflective fabric on two rubber drive shafts. The reduction motor is turned on and drives the two rubber drive shafts to rotate through the second gear and the first gear, thereby driving the roll of wide reflective fabric to rotate. The rubber drive shafts made of rubber have a large frictional force with the roll of wide reflective fabric, so that the rotation of the rubber drive shafts can drive the roll of wide reflective fabric to rotate, while preventing the roll of wide reflective fabric from moving laterally.

[0016] This invention enables the drive motor to rotate the cutting blade at high speed via the first pulley, belt, and second pulley. The servo motor drives the lead screw to rotate, pushing the internal threaded slider and its high-speed rotating cutting blade downwards to cut the wide roll of reflective fabric rotating on the rubber drive shaft.
