Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and more specifically, it relates to a tissue paper cutting and rolling device. Background Technology

[0002] The slitting and rewinding of tissues is a crucial step in the tissue production process. After the papermaking process, a wide strip of raw paper is obtained. At this stage, the paper is too large to be used directly for making everyday tissue products. The slitting and rewinding equipment cuts the wide strip of raw paper according to set specifications, precisely cutting it into strips that meet the width requirements of tissue products. These strips are then rewound to form rolls that meet the requirements of subsequent processing techniques, preparing them for folding, cutting, and packaging, thus producing various sizes of tissue products used in our daily lives.

[0003] When cutting the raw paper for tissues, it is necessary to remove the irregular parts on both sides of the raw paper. These irregular parts are waste paper strips. Most of the existing waste paper strips are piled up at the bottom of the equipment and need to be cleaned manually in a timely manner. Otherwise, too many waste paper strips will affect the normal operation of the cutting equipment and pose a safety hazard. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paper towel cutting and rolling device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tissue cutting and winding device, comprising a frame, on which an unwinding roller and a winding roller are detachably and rotatably connected. A base paper is wound on the unwinding roller. Multiple auxiliary rollers are rotatably connected to the frame. The base paper on the unwinding roller passes sequentially around the multiple auxiliary rollers and winds with the winding roller. A cutting roller is rotatably connected to the frame. Multiple cutters are installed on the cutting roller. The multiple cutters cut waste paper strips from both sides of the base paper. A segmenting mechanism is provided on the frame for cutting the waste paper strips into small segments. A conveyor belt is installed on the frame, located below the segmenting mechanism.

[0006] Preferably, the cutting mechanism includes a drive shaft, a driven shaft, a driven wheel, a drive wheel, blades, and a drive assembly. Both the drive shaft and the driven shaft are rotatably connected to the frame. Two driven wheels are rotatably connected to the driven shaft, and two drive wheels are rotatably connected to the drive shaft. The two drive wheels are located on one side of the two driven wheels, and the waste paper strips pass between the drive wheels and the driven wheels. Multiple blades are fixedly connected to each drive wheel.

[0007] The drive assembly is mounted on the frame and is used to drive the drive shaft and the driven shaft to rotate in opposite directions.

[0008] Preferably, the drive assembly includes a motor and gears. The motor is mounted on a frame, and the output shaft of the motor is connected to one end of the drive shaft via a coupling. Gears are fixedly connected to the drive shaft and the driven shaft, and the two gears mesh with each other.

[0009] Preferably, two symmetrical inclined plates are fixedly connected to the frame, and the two inclined plates are located above the conveyor belt.

[0010] Preferably, a collection box is placed on the ground at one end of the conveyor belt.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Waste paper strips cut from the raw paper are cut into small segments by the cutting mechanism. The small segments of waste paper strips fall onto the conveyor belt, which transports these small segments of waste paper strips to one side of the frame, preventing the waste paper strips from accumulating under the frame and making them easier to collect and clean up after being transported to one side of the frame.

[0013] 2. The waste paper strips pass between the drive wheel and the driven wheel. The drive wheel drives multiple blades on it to rotate. During the rotation, the multiple blades can cut the waste paper strips passing between the drive wheel and the driven wheel, thereby cutting the waste paper strips into multiple small segments, avoiding the waste paper strips from tangling, and the smaller segments of waste paper strips are easier to recycle later.

[0024] Reference Figures 1 to 4This utility model provides a technical solution: a tissue cutting and winding device, including a frame 1, on which an unwinding roller 2 and a winding roller 3 are detachably and rotatably connected. A base paper 6 is wound on the unwinding roller 2. Multiple auxiliary rollers 4 are rotatably connected to the frame 1. The base paper 6 on the unwinding roller 2 passes over the multiple auxiliary rollers 4 in sequence and is wound with the winding roller 3. A cutting roller 5 is rotatably connected to the frame 1. Multiple cutters are installed on the cutting roller 5. The multiple cutters cut waste paper strips 7 from both sides of the base paper 6. The driving methods of the unwinding roller 2, winding roller 3, auxiliary rollers 4, and cutting roller 5 are all existing technologies and will not be described in detail here. A segmenting mechanism is provided on the frame 1 to cut the waste paper strips 7 into small segments. A conveyor belt 8 is installed on the frame 1, and the conveyor belt 8 is located below the segmenting mechanism.

[0025] like Figure 1 and Figure 2 The waste paper strips 7 cut off from the raw paper 6 will be cut into small segments by the cutting mechanism. The small segments of waste paper strips 7 fall onto the conveyor belt 8, which transports these small segments of waste paper strips 7 to one side of the frame 1, preventing the waste paper strips 7 from accumulating under the frame 1. The waste paper strips 7 transported to one side of the frame 1 are also easier to collect and clean.

[0026] Specifically, the cutting mechanism includes a drive shaft 9, a driven shaft 10, a driven wheel 11, a drive wheel 12, blades 13, and a drive assembly. Both the drive shaft 9 and the driven shaft 10 are rotatably connected to the frame 1. Two driven wheels 11 are rotatably connected to the driven shaft 10, and two drive wheels 12 are rotatably connected to the drive shaft 9. The two drive wheels 12 are located on one side of the two driven wheels 11, and the waste paper strips 7 pass between the drive wheels 12 and the driven wheels 11. Multiple blades 13 are fixedly connected to each drive wheel 12.

[0027] The drive assembly is mounted on the frame 1 and is used to drive the drive shaft 9 and the driven shaft 10 to rotate in opposite directions.

[0028] like Figure 3 and Figure 4 The drive assembly drives the drive shaft 9 and driven shaft 10 to rotate in opposite directions. The drive shaft 9 and driven shaft 10 then drive their respective drive wheels 12 and driven wheels 11 to rotate in opposite directions. Figure 3 The driving wheel 12 rotates counterclockwise, and the driven wheel 11 rotates clockwise;

[0029] The waste paper strip 7 passes between the drive wheel 12 and the driven wheel 11. The drive wheel 12 drives multiple blades 13 on it to rotate. During the rotation, the multiple blades 13 can cut the waste paper strip 7 that passes between the drive wheel 12 and the driven wheel 11, thereby cutting the waste paper strip 7 into multiple small segments, avoiding the waste paper strip 7 from tangling, and the smaller segments of waste paper strip 7 are easier to recycle later.

[0030] Specifically, the drive assembly includes a motor 14 and a gear 15. The motor 14 is mounted on the frame 1. The output shaft of the motor 14 is connected to one end of the drive shaft 9 via a coupling. Gears 15 are fixedly connected to the drive shaft 9 and the driven shaft 10 respectively, and the two gears 15 mesh with each other.

[0031] like Figure 3 The motor 14 can drive the drive shaft 9 to rotate. Under the transmission of the two gears 15, the drive shaft 9 and the driven shaft 10 will rotate in opposite directions.

[0032] Specifically, two symmetrical inclined plates 16 are fixedly connected to the frame 1, and the two inclined plates 16 are located above the conveyor belt 8, such as... Figure 2 and Figure 3 The cut waste paper strips 7 will fall between the two inclined plates 16. The two inclined plates 16 guide the waste paper strips 7, thereby ensuring that the cut waste paper strips 7 fall onto the conveyor belt 8 and preventing the cut waste paper strips 7 from falling everywhere.

[0033] Specifically, a collection box 17 is placed on the ground at one end of the conveyor belt 8, such as... Figure 1 The conveyor belt 8 transports the cut waste paper strips 7 to the collection box 17, completing the collection of waste paper strips 7.

[0034] Working principle: The drive assembly drives the drive shaft 9 and driven shaft 10 to rotate in opposite directions. The drive shaft 9 and driven shaft 10 drive the drive wheel 12 and driven wheel 11 on them to rotate in opposite directions, respectively. The waste paper strip 7 passes between the drive wheel 12 and driven wheel 11. The drive wheel 12 drives multiple blades 13 on it to rotate. During the rotation, the multiple blades 13 can cut the waste paper strip 7 that passes between the drive wheel 12 and driven wheel 11, thereby cutting the waste paper strip 7 into multiple small segments. The cut waste paper strip 7 falls onto the conveyor belt 8. The conveyor belt 8 transports the cut waste paper strip 7 into the collection box 17, completing the collection of waste paper strip 7.

[0035] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a processor, alarm module, or drive module, etc., to control conventional known devices. All standard parts used in this application can be purchased from the market.
