[0023] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0024] An embodiment of the present application provides an automatic winding cutting mechanism, wherein the cutting mechanism 100 is located on one side of a winder and is arranged close to a winding station of the winder, and the cutting mechanism 100 is used to cut off the product upstream of a fully wound winding shaft in the winding station so that the winder can change the roll.

[0025] like Figure 1 , 2 As shown, the cutting mechanism 100 includes: a swing arm 1, a transition roller 2 and a pressure roller 3 rotatably arranged on the swing arm 1, a hot cutting component 4 slidably arranged on the swing arm 1, and an air duct 5 arranged on the swing arm 1.

[0026] The swing arm 1 includes a front portion 11 and a rear portion 12 that are away from each other. The swing arm 1 is set on one side of the winding station and can swing around a center line X1 extending in the left-right direction. The center line X1 passes through the rear portion 12 of the swing arm 1. The swing arm 1 has a first position in which the front portion 11 extends into the winding station and a second position in which the front portion 11 is away from the winding station. The swing arm 1 swings between the first position and the second position. The front portion 11 is hook-shaped, and the transition roller 2, the hot cutting component 4, the air duct 5 and the pressure roller 3 are sequentially arranged along the arc of the front portion 11. The front portion 11 has an opening for the winding shaft of the winding station to enter, so that the pressure roller 3 can press the winding shaft and the hot cutting component 4 can cut the product upstream of the winding shaft.

[0027] like Figure 2 As shown, in the embodiment of the present application, the winding shaft extends in the left-right direction and is parallel to the center line X1, and the transition roller 2 and the pressure roller 3 are both parallel to the winding shaft. The transition roller 2 is arranged at the front of the swing arm 1 so as to be rotatable around its own axis. The pressure roller 3 can rotate around its own axis and move along the straight line Y1 perpendicular to the center line X1; when the swing arm 1 rotates to the first position, the pressure roller 3 moves along the straight line to press the product on the winding shaft, so that the product upstream of the winding shaft is tightened between the transition roller 2 and the pressure roller 3, so that the hot cutting component 4 can cut off the product upstream of the winding shaft, so that the winding machine can automatically change the shaft.

[0028] A clamping cylinder 6 is provided on the swing arm 1, and the clamping roller 3 is rotatably connected to the clamping cylinder 6, and moves back and forth along the straight line Y1 under the drive of the clamping cylinder 6, so as to approach and move away from the winding shaft when the swing arm 1 is in the first position.

[0029] like Figure 2 , 3 As shown, the hot cutting component 4 includes at least one blade 41 and at least one heating rod 42 for heating the at least one blade 41, and the at least one blade 41 can move back and forth along a cutting path to cut the product between the transition roller 2 and the pressure roller 3, and the cutting path is located between the transition roller 2 and the pressure roller 3 and extends along the first direction; in the present application, the hot cutting component 4 includes a blade 41 and a heating rod 42, and the heating rod 42 increases the temperature of the blade 41, which is beneficial for the blade 41 to cut the product, especially the thicker and more elastic film-like products, and the cut surface is smooth, which is not easy to cause product waste.

[0030] The cutting mechanism 100 also includes a rodless cylinder 7 that drives the hot cutting component 4 to slide back and forth. The rodless cylinder 7 is fixedly arranged at the front part 11 of the swing arm 1. The rodless cylinder 7 includes a cylinder body 71 extending in the left and right directions and a slider 72 slidably arranged on the cylinder body 71. The hot cutting component 4 is fixedly mounted on the slider 72, and the product is cut as the slider 72 slides in the left and right directions.

[0031] The hot cutting assembly 4 also includes a conductive plate 43 disposed on the slider 72 , and the heating rod 42 is electrically connected to the conductive plate 43 so as to heat the blade 41 .

[0032] Continue to refer to Figure 2 and Figure 3 The air duct 5 is arranged between the pressing roller 3 and the transition roller 2. The air duct 5 extends in the left-right direction and has a plurality of air outlets 51 in sequence in the left-right direction. Each air outlet 51 faces the transition roller 2. The air duct 5 is used to distribute the flowing air to each air outlet 51 in sequence. Each air outlet 51 sprays the flowing air toward the transition roller 2 to blow up the product bypassing the transition roller 2, so that the blown product is pressed against the winding shaft to facilitate the product rolling.

[0033] The air duct 5 is fixedly connected to the rodless cylinder 7. A support plate 8 is connected between the cylinder body 71 of the rodless cylinder 7 and the air duct 5. The support plate 8 extends from the cylinder body 71 to between the transition roller 2 and the clamping roller 3. The support plate 8 is arranged to avoid the hot cutting mechanism 4 and the slider 72.

[0034] The working principle of the present application is as follows: when the winding shaft of the winding station is fully rolled, the swing arm 1 swings from the second position to the first position, the heating rod 42 preheats the blade 41, and the clamping cylinder 6 drives the clamping roller 3 to extend along the straight line Y1 to clamp the fully rolled winding shaft, and make the product between the winding shaft and the transition roller 2 be tightened, and the preheated blade 41 moves in the left and right directions under the drive of the rodless cylinder 7 to cut the product between the clamping roller 3 and the transition roller 2. After the cutting is completed, the heating rod 42 stops heating and the rodless cylinder 7 is reset; the winding machine changes the roll, and the winding shaft with an empty roll is turned into the winding machine. At the work station, several air outlets 51 of the air duct 5 spray flowing air outward, and the beginning of the product bypassing the transition roller 2 is blown up by the flowing air sprayed from the air duct 5 and sticks to the winding shaft of the empty roll, and the clamping cylinder 6 drives the clamping roller 3 to move toward the winding shaft of the empty roll to press the beginning of the product on the winding shaft of the empty roll, and the winding shaft of the empty roll rotates around the axis line to roll up, and when the winding shaft of the empty roll is rolled up 3-5 times, the air duct 5 stops blowing air, the clamping cylinder 6 drives the clamping roller 3 away from the winding shaft to reset, and the swing arm 1 swings from the second position to the first position to wait for the winder to change the roll next time.

[0035] The present application uses a heated blade to cut the product, which makes it easy to cut the product and ensures a smooth cross-section, thereby improving the cutting effect; an air duct 5 is arranged near the hot cutting component 4 to blow up the cut product, thereby facilitating the rolling of the product, avoiding wrinkles at the beginning of the product, and improving the winding efficiency, and is particularly suitable for elastic film products.

[0036] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application.
