Description

Technical Field

[0001] This invention relates to the technical field of tissue paper cutting and processing mechanisms, and particularly to a fully automatic tissue paper cutting mechanism. Background Technology

[0002] Facial tissues are a type of cleaning paper product with good toughness, flexibility, and water resistance. They are essential to people's daily lives and are widely loved by consumers. The raw paper for facial tissues is very wide and needs to be cut into rolls of specified sizes by an automatic slitting mechanism.

[0003] After the raw paper from the unwinding system enters the automatic slitting mechanism, it is tensioned by tension rollers and then automatically descends to a designated depth, cutting the wider raw paper into multiple strips of equal size. Finally, multiple paper tubes mounted on the take-up rollers rewind each strip, completing the fully automatic slitting of facial tissues.

[0004] After the paper roll is wound to a specified length, the paper roll needs to be removed and replaced with an empty paper roll. In existing paper roll removal or installation structures, both ends of the expansion shaft need to be removed from the frame, and the expansion shaft needs to be lifted out using hoisting equipment. Finally, the paper roll is released from the expansion shaft by venting air. The roller is quite heavy, and hoisting equipment is required for loading and unloading the winding roll. Each loading and unloading of the expansion shaft requires machine downtime. This connection method, requiring disassembly and inflation / deflation at both ends, results in low paper roll production efficiency and inconvenience. Summary of the Invention

The clamping module clamps the main shaft body A2, and the top block telescopic component extends the top block assembly outward to press the new tissue roll tightly. In this structure, when the tissue roll is removed or installed, only one side of the clamping module needs to be loosened, without removing the entire roll, reducing labor intensity. Moreover, the use of hoisting equipment improves the efficiency of tissue roll replacement, making it more convenient to use.

[0020] In a preferred embodiment of the present invention, the swing shaft 9 is arranged vertically; the vertically arranged swing shaft 9 allows the rotating seat body A1 to swing horizontally, facilitating the loading and unloading of the paper tube.

[0021] In a preferred embodiment of the present invention, the rotating seat body A1 includes a rotating seat 1; a main rotating shaft 103 is fixed on the rotating seat 1; the clamping module includes a fixed hoop 2 fixed on the rotating seat 1 and a movable hoop 3 hinged to the fixed hoop 2; the movable hoop 3 and the fixed hoop 2 are connected and fixed by a locking member.

The pin G is detachably connected to the rotating seat 1. The fixed hoop 2 and the movable hoop 3 are connected as one unit and locked onto the main shaft A2 by a pin G passing through the shaft hole 101 of the seat body and being inserted into the second pin hole 302 and the first pin hole 201.

[0023] In a preferred embodiment of the present invention, the spindle head 501 of the main spindle body A2 is provided with an insert 502; the inner surface of the fixing hoop 2 is provided with a keyway 203 that matches the insert 502; the inner hole formed by the movable hoop 3 and the fixing hoop 2 matches the spindle head 501. Before the spindle head 501 of the main spindle body A2 is installed on the fixing clamp 2, the keyway 203 and the insert 502 need to be aligned. The keyway 203 and the insert 502 are used to prevent the main spindle body A2 from slipping relative to the fixing clamp 2, so that the main spindle body A2 will not slip relative to the rotating seat 1.

[0024] In a preferred embodiment of the present invention, a permanent magnet H is fixed on the pin G; a positioning ring 102 is fixed on the rotating seat 1; both the positioning ring 102 and the rotating seat 1 are made of materials that can be attracted and fixed by the permanent magnet H; the pin G is attracted and fixed on the rotating seat 1 by the permanent magnet H, so that the pin G is not easy to fall off the rotating seat 1.

[0026] In a preferred embodiment of the present invention, the main shaft body A2 includes a hollow take-up shaft 5; the top block telescopic member is a movable shaft 7 slidably connected to the inner cavity of the take-up shaft 5; the top block assembly consists of a plurality of top blocks 6 distributed circumferentially on the take-up shaft 5; a guide block 601 is connected to the top block 6; a top block guide groove 504 slidably connected to the top block 6 is provided on the outer wall of the take-up shaft 5; a slider guide groove 505 communicating with the inner cavity of the take-up shaft 5 is provided at the bottom of the top block guide groove 504. The slider guide groove 505 is slidably connected to the guide block 601; the end of the guide block 601 that extends into the inner cavity of the take-up shaft 5 is provided with a top wedge-shaped surface 602; the movable shaft 7 is provided with a tapered surface 702 at the position directly opposite the top wedge-shaped surface 602; the rotating seat body A1 is provided with a convex shape 104a in the shape of a spherical surface; a spring 10 fixed to the movable shaft 7 is connected inside the take-up shaft 5; the end face of the movable shaft 7 that contacts the convex shape 104a is provided with a spherical head surface 701; The guide block 601 is provided with a limit stop, which can completely prevent the top block 6 from being released from the top block guide groove 504; When the take-up shaft 5 is misaligned with the rotating seat body A1, the thrust of the spring 10 pushes the movable shaft 7, causing the conical surface 702 to loosen its grip on the top block wedge surface 602, allowing the paper tube to be loaded onto the take-up shaft 5. When the take-up shaft 5 is aligned with the rotating seat body A1, the convex shape 104a overcomes the elastic force of the spring 10 and pushes the movable shaft 7, causing the conical surface 702 to press against the top block wedge surface 602. The conical surface 702 pushes the top block 6 outward, clamping it onto the paper tube, thus fixing the paper tube on the take-up shaft 5. When the take-up shaft 5 is aligned with the rotating seat body A1, the top block 6 is pushed out, thus fixing the paper tube on the take-up shaft 5. After the take-up shaft 5 rotates around the swing shaft 9 until it is misaligned with the rotating seat body A1, the top block 6 automatically releases its grip on the paper tube, simplifying the steps of disassembling and positioning the paper tube on the take-up shaft 5. Additionally, a paper tube positioning protrusion 503 is provided around the top block 6 to enhance the strength of that position.

[0027] In a preferred embodiment of the present invention, multiple arc-shaped protrusions 602a are provided on the surface of the top block wedge surface 602; the arc-shaped protrusions 602a form line contact with the conical surface 702, reducing the resistance between the conical surface 702 and the top block wedge surface 602, making the sliding of the movable shaft 7 smoother.

[0028] In a preferred embodiment of the present invention, the rotating seat body A1 is provided with a threaded hole; a bolt 104 is threadedly connected to the threaded hole; a convex shape 104a is provided at the end of the bolt 104; in practical applications, the threaded hole is coaxially provided on the main rotating shaft 103 and passes through both ends of the main rotating shaft 103; by rotating the bolt 104, the extension amount of the convex shape 104a can be adjusted, the amount of compression of the movable shaft 7 by the convex shape 104a can be adjusted, and the amount of outward extension of the top block 6 can be adjusted, so as to achieve the force of the paper tube being pressed by the top block 6. This can ensure that the top block 6 has sufficient pressing force to press against the paper tube, prevent the paper tube from slipping, and also avoid the paper tube from being deformed due to excessive pressing force of the top block 6.

[0029] Beneficial effects of this invention: 1. When removing or installing the paper towel roll, only one side of the clamping module needs to be loosened. The roll can be rotated around the swing axis until it is misaligned with the main body of the rotating seat, without having to loosen the connection at both ends to remove the entire roll. Moreover, the connection position between the main shaft and the main body of the rotating seat is in the swing direction of the main shaft, so only the main shaft needs to be swung horizontally. There is no need to use lifting equipment to lift the main shaft, which reduces labor intensity, improves the paper roll replacement efficiency, and makes it more convenient to use. There is no need to equip multiple main shafts. 2. After the empty paper tube is inserted into the main shaft, the main shaft rotates around the swing axis until it aligns with the convex shape. During the swinging process, the main shaft acts directly on the head of the movable shaft through the convex surface, pressing the movable shaft firmly. The positioning of the paper tube on the main shaft and the positioning of the main shaft itself on the rotating seat body are synchronized. That is, in addition to the alignment and misalignment of one end of the main shaft with the rotating seat body in two directions around the swing axis, the paper tube can also be positioned and released on the main shaft body respectively. That is, when one end of the main shaft body is aligned with the rotating seat, the main shaft body is positioned on the rotating seat body and the paper tube is positioned on the main shaft body at the same time; conversely, when one end of the main shaft body is misaligned with the rotating seat body, the main shaft body is released on the rotating seat body and the paper tube is also released on the main shaft body. These two sets of movements are completed synchronously, making the positioning and release of the paper tube on the main shaft body more convenient and faster, simplifying the steps of positioning and releasing the paper tube on the main shaft body. 3. The connection between the spindle body and the rotary seat body is achieved by a combination of a fixed clamp and a movable clamp, which are then tightened together. A keyway and insert are used to further secure them as a single unit. A pin connects the fixed clamp and the movable clamp quickly, and the pin is magnetically attached to the positioning ring. Therefore, the fixed clamp and the movable clamp can be quickly disassembled, facilitating rapid assembly and disassembly between the spindle body and the rotary seat body. 4. During the movement of the movable shaft, multiple conical surfaces simultaneously push each top block to lock the paper tube synchronously, resulting in high paper tube positioning efficiency and improved paper tube replacement efficiency.
