Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking equipment, and particularly relates to a paper winder for papermaking. Background Art

[0002] A paper machine is used for paper manufacturing. After the paper is manufactured, the paper needs to be wound around a paper roll through the rotation of the paper roll, so as to facilitate the winding and collection of the paper. After the paper winding is completed, the wound paper roll needs to be taken out from the frame of the paper machine to facilitate the transfer of the wound paper roll to the next process. When removing the wound paper roll from the existing paper winder, since the paper wound on the paper roll is heavy, a lifting device such as a crane often needs to be equipped above the paper winder. The lifting device is used to remove the wound paper roll from the paper winder. Manual operation is time-consuming and laborious, and the overall floor area of the device is large, and the whole operation process is relatively cumbersome, which affects the use efficiency of the paper winder. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a paper winder for papermaking, which includes a paper roll support, a winding motor, two roll-changing tracks and a plurality of paper rolls.

[0004] The paper roll support includes two symmetrically arranged hydraulic cylinders and a slope arranged between the two hydraulic cylinders. The top of the slope is arranged on the right side of the hydraulic cylinder, and the bottom of the slope is arranged on the left side of the hydraulic cylinder. The fixed end of the hydraulic cylinder is fixedly arranged on the ground. A support block is arranged at the top of the telescopic end of the hydraulic cylinder. An arc-shaped groove matching the roller shaft of the paper roll is arranged at the upper end of the support block. The roller shafts on both sides of the paper roll are placed on the corresponding grooves and are rotationally connected with the grooves. A sensor is arranged on the side of the fixed end of the hydraulic cylinder close to the slope;

[0005] The two roll-changing tracks are located at the upper left side of the slope and are symmetrically arranged on both sides of the slope. The roll-changing track includes a horizontal track, an inclined track and a track support. The right side of the horizontal track corresponds to and is fixedly connected with the left side of the inclined track, and the lower side of the horizontal track is fixedly connected with the track support. The right side of the inclined track abuts against both sides of the groove when the hydraulic cylinder extends. The roller shafts at both ends of the paper roll pass through the corresponding roll-changing tracks and are slidably connected with the roll-changing tracks;

[0006] The winding motor is arranged on the side of the support block away from the slope. The winding motor is provided with a motor support and a gear one. The motor support is L-shaped, and the upper end of the motor support is fixedly connected with the outer shell of the winding motor. The right end of the motor support is fixedly connected with the support block. The gear one is coaxially and drivingly connected with the output shaft of the winding motor. Gear two matching the gear one is arranged at both ends of the roller shaft of the paper roll. The gear one and the gear two are meshed with each other.

[0007] Furthermore, a horn-shaped track inlet is arranged on the left side of the horizontal track, so that the replaceable paper roll can be accurately placed into the roll-changing track.

[0008] Further, a controller is provided outside the paper roll bracket. The inductor and the hydraulic cylinder are both electrically connected to the controller through wires. The inductor is used to sense the size of the rolled paper. When the rolled paper blocks the signal between the inductors, the controller receives the electrical signal from the inductor and controls the hydraulic cylinder to contract. When the hydraulic cylinder contracts, the upper part of the telescopic end of the hydraulic cylinder is lower than the roller shaft of the paper roll, and the rolled paper falls on the slope and rotates along the slope and is removed. When the rolled paper does not block the signal between the inductors, the controller controls the hydraulic cylinder to extend and resume abutting against the inclined guide rail.

[0009] Further, half of the distance from the horizontal track to the slope surface is greater than the distance from the inductor to the roller shaft of the paper roll, so as to prevent the rolled paper from contacting the horizontal guide rail or the paper roll slidably arranged on the horizontal guide rail when rotating on the slope, thereby affecting the removal of the rolled paper.

[0010] The present utility model further includes other devices or components that can enable the paper roll paper machine to be used normally, which are all conventional technical means in the art. In addition, the paper roll and the inductor not defined in the present utility model both adopt conventional technical means in the art.

[0011] The working principle of the present utility model is that the device slides the paper roll into the groove through the roll-changing track. At the same time, the first gear and the second gear are engaged to drive the paper roll to rotate and start the paper-rolling operation. After the rolled paper blocks the inductor, the hydraulic cylinder supports the rolled paper to descend. The rolled paper falls on the slope and is removed. The hydraulic cylinder extends to abut against the inclined guide rail, and the replaced paper roll slides into the groove through the roll-changing track to restart the paper-rolling.

[0012] The beneficial effect of the present utility model is that the device is not equipped with a lifting device such as a crane, and uses a simple mechanism to realize the paper roll changing operation, which not only saves manpower and material resources, but also has a small overall floor area of the device, a simple operation process, and improves the use efficiency of the paper roll machine.

[0017] The present invention is described in detail below in conjunction with the drawings and specific embodiments in the embodiments of the present invention. The description here is only used to explain the present invention, but not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the present invention.

[0018] Example

[0019] like Figures 1 to 3 As shown, the utility model provides a papermaking paper reel, which includes a paper roll support, a paper reel motor 1, two roll changing rails and a plurality of paper rolls 2.

[0020] The paper roller support includes two symmetrically arranged hydraulic cylinders 3 and a slope 4 arranged between the two hydraulic cylinders 3. The top of the slope 4 is arranged on the right side of the hydraulic cylinder 3, and the bottom of the slope 4 is arranged on the left side of the hydraulic cylinder 3. The fixed end of the hydraulic cylinder 3 is fixedly arranged on the ground. A support block 14 is arranged on the top of the telescopic end of the hydraulic cylinder 3. The upper end of the support block 14 is provided with an arc-shaped groove 5 matching the roller shaft of the paper roller 2. The rollers on both sides of the paper roller 2 are placed on the grooves 5 on the corresponding sides and are rotatably connected with the grooves 5. A sensor 6 is arranged on the fixed end of the hydraulic cylinder 3 close to the side of the slope 4.

[0021] Two roller changing tracks are located at the upper left side of the slope 4 and are symmetrically arranged on both sides of the slope 4. The roller changing tracks include a horizontal track 7, an inclined track 8 and a track bracket 9. The right side of the horizontal track 7 corresponds to and is fixedly connected to the left side of the inclined track 8, and the track bracket 9 is fixedly connected to the lower side of the horizontal track 7. When the hydraulic cylinder 3 is extended, the right side of the inclined track 8 abuts against both sides of the groove 5. The rollers at both ends of the paper roller 2 pass through the roller changing tracks on the corresponding side and are slidably connected to the roller changing tracks.

[0022] The paper reel motor 1 is arranged on a side of the support block 14 away from the slope 4. The paper reel motor 1 is provided with a motor bracket 10 and a gear 11. The motor bracket 10 is L-shaped, and the upper end of the motor bracket 10 is fixedly connected to the shell of the paper reel motor 1, and the right end of the motor bracket 10 is fixedly connected to the support block 14. The gear 11 is coaxial with the output shaft of the paper reel motor 1 and is transmission-connected.

[0023] As a further measure of the present utility model, a trumpet-shaped track inlet 13 is provided on the left side of the horizontal track 7, facilitating the accurate placement of the replaceable paper roll 2 into the roll-changing track; a controller (not shown in the figure) is provided outside the paper roll bracket, and both the sensor 6 and the hydraulic cylinder 3 are electrically connected to the controller through wires. The sensor 6 is used to sense the size of the rolled paper. When the rolled paper blocks the signal between the sensors 6, the controller receives the electrical signal from the sensor 6 and controls the contraction of the hydraulic cylinder 3. When the hydraulic cylinder 3 contracts, the upper part of the telescopic end of the hydraulic cylinder 3 is lower than the roller shaft of the paper roll 2, and the rolled paper falls on the slope 4 and rotates along the slope 4 and is removed. When the rolled paper does not block the signal between the sensors 6, the controller controls the hydraulic cylinder 3 to extend and resume abutting against the inclined guide rail 8; half of the distance from the horizontal track 7 to the slope surface of the slope 4 is greater than the distance from the sensor 6 to the roller shaft of the paper roll 2, preventing the rolled paper from contacting the horizontal guide rail 7 or the paper roll 2 slidably arranged on the horizontal guide rail 7 when rotating on the slope 4, thereby affecting the removal of the rolled paper.

[0024] The working principle of the present utility model is that the device slides the paper roll 2 into the groove 5 through the roll-changing track. At the same time, the first gear 11 and the second gear 12 are engaged to drive the paper roll 2 to rotate and start the paper rolling operation. After the rolled paper blocks the sensor 6, the hydraulic cylinder 3 supports the rolled paper to descend. The rolled paper falls on the slope 4 and is removed. The hydraulic cylinder 3 extends to abut against the inclined guide rail 8, and the replaceable paper roll 2 slides into the groove 5 through the roll-changing track to restart the paper rolling.

[0025] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
