Description

Technical Field

[0001] This utility model relates to the field of membrane material winding, specifically to a non-stop winding mechanism. Background Technology

[0002] Existing winding machines on the market, when winding film materials (such as PET, PP, tape, and specialty paper), often require stopping to replace the core at high speeds to maintain stable production, resulting in low efficiency.

Furthermore, when switching between different cores, the cutting mechanism cannot effectively control the length of the cut tail material, leading to uneven core bottoms and affecting winding quality. Therefore, there is an urgent need for a winding mechanism that can simultaneously handle cores of different sizes, perform non-stop winding, and deliver excellent winding quality.

[0104] Please see Figure 9 The smoothing mechanism 500 is a brush. In this specific embodiment, in order to solve the problems of uneven lengths of the tail material caused by cutting and uneven strip material that may occur during the initial winding stage of the core, the brush 500 used with the cutter 404 can smooth the cut film material and avoid warping of the film material during the winding process.

[0105] Please see Figure 2 The receiving module 200 includes:

[0106] A servo rotary motor (not shown in the figure) is mounted in the second mounting base 201;

[0107] The rotating frame 202 is connected to the output shaft of the servo rotary motor;

[0108] Two take-up shafts 203 are arranged in a circle on the rotating frame. In this specific embodiment, the take-up shafts are air-expanding shafts.

[0109] A winding motor (not shown in the figure) has its output shaft connected to the winding shaft. The winding motor provides a power source to rotate the winding shaft to wind up the film material.

[0110] The working principle of this utility model is as follows: This winding mechanism can adapt to the winding of different types of cores. Cores of different sizes are fitted onto the winding shaft 203 of the winding module 200. For example, two winding shafts 203 are fitted with 3-inch and 6-inch cores respectively. When the active drive roller 102 and the transition roller 103 start to drive the film material, the servo rotary motor drives the rotating frame 202 to rotate the winding shaft 203 fitted with the 6-inch core to the winding position. The pressure roller 303 moves towards the 6-inch core under the action of the first sliding component 301 and the second sliding component 302, and adjusts the film material in real time according to the winding thickness to maintain a suitable pressing distance with the surface of the 6-inch core. The winding shaft 203 winds up the film under the action of the winding motor. The process involves the following steps: When the 6-inch core is wound up, the servo rotary motor is activated to rotate, and the winding shaft with the 3-inch core rotates to the winding position. The pressure roller presses the film material against the surface of the 3-inch core. At this time, the primary cylinder 406 and the secondary cylinder 407 are activated to perform the cutting operation. The brush 500, which works in conjunction with the cutter 404, smooths the cut film material to prevent warping. After the pressure roller adjusts the pressing distance synchronously, the 3-inch core is wound up without stopping the machine. Similarly, if the 3-inch core is wound up first, and then the servo rotary motor is activated to rotate, the winding shaft with the 6-inch core rotates to the winding position. Since the 6-inch core has a larger outer diameter, only the primary cylinder 406 needs to be activated for cutting. This invention's non-stop winding mechanism achieves high-speed, non-stop, and speed-free roll changing, and enables instantaneous piercing and cutting of the film material at 300 m / min.

[0111] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
