From pull-out paper towels for daily household use to small-sized paper towels for hotels, and large-sized wiping paper towels for industrial use, different scenarios have different requirements for the size and shape of paper towels. In order to meet market demand, paper towel manufacturers need to frequently switch cutting specifications.

[0003] Place one end of the tissue paper that needs to be cut under the slitting blade, and then place the cut tissue paper on the outside of the winding roller. When the winding roller pulls and rolls up the tissue paper, the slitting blade will cut the tissue paper.

[0004] Existing adjustable tissue paper slitting devices require the use of a wrench to adjust the spacing of the slitting blades, which is a cumbersome process and makes it difficult to ensure the consistency of the spacing. It is also inconvenient to press the rolled tissue paper tightly. Therefore, an adjustable tissue paper slitting device is proposed. Utility Model Content

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present invention. This embodiment provides an adjustable paper towel cutting device, including a support frame 1, an adjustment mechanism 2 provided in the inner cavity of the support frame 1, and a pressing mechanism 3 provided on one side of the support frame 1.

[0030] Adjustment mechanism 2 includes fixed blocks 204 symmetrically installed on the top of support frame 1. Positive and negative screws 206 are provided on opposite sides of the two fixed blocks 204. A Y-shaped frame 207 is installed on the outer side of the positive and negative screws 206 through a threaded sleeve. A dividing slice 209 is provided on the inner side of the Y-shaped frame 207. A top flat roller 201 is symmetrically installed on the inner surface of support frame 1.

[0031] Specifically, there are multiple Y-shaped frames 207, all of which are connected to the positive and negative lead screws 206 via threaded sleeves. They are evenly distributed on the outside of the positive and negative lead screws 206. The positive and negative lead screws 206 are rotatably connected inside the fixed block 204. When the positive and negative lead screws 206 rotate, they drive the Y-shaped frames 207 to move. Because the threads of the positive and negative lead screws 206 are symmetrical and designed in both directions, the symmetrical Y-shaped frames 207 can move simultaneously in the same or opposite directions. The paper slices 209 are rotatably connected in the Y-shaped frames 207 to cut the paper towels.

[0032] Slide rods 205 are symmetrically installed on the inner surface of the support frame 1. A reinforcing block 208 is fixedly installed in the middle part of the slide rod 205. A servo motor 210 is fixedly installed through the fixing block 204 at one end of the positive and negative lead screws 206.

[0033] Specifically, when the output end of the servo motor 210 drives the forward and reverse lead screws 206 to rotate, it drives each pair of Y-shaped frames 207 symmetrical along the reinforcing block 208 to move towards or away from each other. Under the action of the reinforcing block 208, several Y-shaped frames 207 are arranged symmetrically on both sides of the reinforcing block 208. When the Y-shaped frames 207 move, it can ensure that the spacing between each pair of Y-shaped frames 207 is the same.

[0034] Multiple paper feeding rollers 202 are installed on the inner surface of the support frame 1 and on one side of the top flat roller 201, and a paper output roller 203 is provided on the inner surface of the support frame 1 and on the other side of the top flat roller 201.

[0035] Specifically, multiple paper feed rollers 202 and one paper output roller 203 are rotatably connected inside the support frame 1. The paper towel is pulled from the bottom of the bottom paper feed roller 202 to the outside of the middle paper feed roller 202, and then from the top of the middle paper feed roller 202 to the top of the top paper feed roller 202. The top paper feed roller 202 is kept at the same level as the two top flat rollers 201. Finally, the paper towel is placed on the top of the two top flat rollers 201 and then passes through the bottom of the paper output roller 203 for winding.

[0036] The slice 209 is located at the top of the center of the two servo motors 210 on opposite sides. Several Y-shaped frames 207 are slidably connected to the outside of the slide bar 205. The other end of the reinforcing block 208 is rotatably connected to the middle of the positive and negative lead screws 206.

[0037] Specifically, several cutting slices 209 are located at the top center of the middle of the two servo motors 210 on opposite sides. Since the two servo motors 210 are both circular, the top center of the two servo motors 210 on opposite sides can accommodate the cutting slices 209. The cutting slices 209 use this space to smoothly cut the paper towel.

[0038] Furthermore, the paper towel is first pulled from the bottom of the lowest paper feed roller 202 to the outside of the middle paper feed roller 202, then pulled from the top of the middle paper feed roller 202 to the top of the highest paper feed roller 202. Finally, the paper towel is placed on top of the two top flat rollers 201. At this time, the operation of the servo motor 210 is controlled. The output end of the servo motor 210 drives the positive and negative lead screws 206 to rotate. The positive and negative lead screws 206 drive each pair of symmetrical Y-shaped frames 207 to move simultaneously on both sides of the reinforcing block 208 until each pair of Y-shaped frames 207 is adjusted to a suitable width, and the paper towel can be cut.

[0039] Example 2

[0040] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a pressing mechanism 3 that can compact the rolled-up paper towel.

[0041] The clamping mechanism 3 includes L-shaped groove blocks 301 symmetrically installed on one side of the support frame 1. A U-shaped frame 304 is fixedly installed on the top of the L-shaped groove blocks 301. A slide plate 307 is provided inside the U-shaped frame 304. An arc plate 308 is installed at the bottom of the slide plate 307. A winding roller 303 is provided on the opposite side of the two L-shaped groove blocks 301.

[0042] Specifically, the slide plate 307 is slidably connected inside the U-shaped frame 304, and the arc plate 308 is rotatably connected to the bottom of the slide plate 307. When the take-up roller 303 takes up the paper towel, the slide plate 307 presses the arc plate 308 tightly against the outside of the paper towel, thus compacting the taken-up paper towel.

[0043] The U-shaped frame 304 has multiple limit pins 305 evenly distributed inside, the slide plate 307 has multiple springs 306 evenly distributed on the top, the L-shaped groove block 301 has a rotating shaft 302 inside, and one end of the rotating shaft 302 passes through the L-shaped groove block 301 and is fixedly installed with a winding motor 309.

[0044] Specifically, the rotating shaft 302 is rotatably connected inside the L-shaped groove block 301, and the winding roller 303 can be inserted into the rotating shaft 302 from the groove of the L-shaped groove block 301, making it easy to remove the paper towel that has been wound on the outside of the winding roller 303.

[0045] The number of springs 306 is the same as the number of limit pins 305, and the springs 306 are located outside the limit pins 305. The winding roller 303 is movably inserted into the inside of the rotating shaft 302.

[0046] Specifically, under the action of several springs 306, when the winding roller 303 is winding the paper towel, the springs 306 push the slide plate 307 to move downward inside the U-shaped frame 304, pressing the arc plate 308 tightly against the outside of the paper towel. As the paper towel roll slowly thickens, with the assistance of several limit pins 305, the slide plate 307 moves upward steadily. During the movement, the arc plate 308 remains in close contact with the outside of the paper towel roll.

[0047] Furthermore, the slit tissues are wrapped around the outside of the take-up roller 303. The take-up motor 309 is controlled to run. The output end of the take-up motor 309 drives the rotating shaft 302 to rotate. The rotating shaft 302 drives the take-up roller 303 to rotate, thus taking the tissues in. At this time, under the action of several springs 306, the slide plate 307 is pushed downward inside the U-shaped frame 304. The slide plate 307 pushes the arc plate 308 onto the tissues outside the take-up roller 303. When the take-up roller 303 is taking the tissues in, the arc plate 308 presses the tissues firmly.

[0048] Working principle: First, the paper towel is pulled from the bottom of the bottom feed roller 202 to the outside of the middle feed roller 202. Then, the paper towel is pulled from the top of the middle feed roller 202 to the top of the top feed roller 202. Finally, the paper towel is placed on top of the two top flat rollers 201. At this time, the paper towel is located at the bottom of several slitting pieces 209. Then, the paper towel is pulled towards the bottom of the output roller 203. Finally, the end of the paper towel is wrapped around the outside of the take-up roller 303. At this time, the operation of the take-up motor 309 is controlled. The take-up motor 309 drives the rotating shaft 302 to rotate in the L-shaped groove block 301. The rotating shaft 302 drives the take-up roller 303 to rotate, thus taking up the slitting paper towel. During the take-up process, under the action of several springs 306, the springs 306 push the slide plate 307 downward inside the U-shaped frame 304. The slide plate 307 pushes the arc plate 309 downward. 8. Covering the outside of the paper towel roll, a downward force is applied to the paper towel to roll it up tightly. During the winding process of the winding roller 303, the paper towel located at the slitting slice 209 is pulled. After the paper towel is pulled, several slitting slices 209 cut the paper towel into equal widths. When it is necessary to adjust the width of the slitting slices 209 to cut paper towels of different widths, the operation of the fixing block 204 is controlled. The output end of the fixing block 204 drives the positive and negative lead screws 206 to rotate in the two positive and negative lead screws 206. The positive and negative lead screws 206 move multiple Y-shaped frames 207 on the outside. With the reinforcing block 208 as the center of symmetry, the Y-shaped frames 207 located on both sides of the slitting slice 209 move simultaneously towards or in opposite directions. Under the action of the slide rod 205, only the Y-shaped frames 207 are allowed to move, restricting the rotation of the Y-shaped frames 207. After adjusting the distance between every two slitting slices 209, the paper towel can be cut.

[0049] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
