Description

Technical Field

[0001] This utility model relates to the field of tissue paper processing technology, specifically to an unwinding device for producing handkerchief paper. Background Technology

[0002] The production of handkerchief tissues involves multiple processes, such as printing and folding. Unwinding unfolds large rolls of raw paper, allowing them to smoothly enter the next production stage and ensuring efficient and continuous operation of each process. For example, in the production of pre-printed colored facial tissues, the paper roll must be unwound before printing and subsequent processing can begin. During the unwinding process, the paper tension can be adjusted to maintain the appropriate tightness on the production line. This helps ensure the quality of the handkerchief tissues, such as their flatness and strength, and prevents problems such as paper breakage or wrinkles.

[0003] When unwinding rolls of handkerchief paper, existing handkerchief paper machines may not have flexible or stable fixing methods for placing and securing the paper rolls, making it difficult to adapt to the placement requirements of paper rolls of different sizes. This may cause problems such as shaking and displacement of the paper rolls during the unwinding process, affecting the stability of unwinding and the quality of handkerchief paper production.

[0004] Therefore, how to flexibly adjust the clamping method according to the length of the paper roll is a problem that needs to be solved now. Utility Model Content

[0005] In view of this, the present invention provides an unwinding device for the production of handkerchief paper. The device uses a flexibly adjustable clamping component to clamp and fix paper rolls of different lengths, avoiding problems such as shaking and displacement during the unwinding process. At the same time, the heating component heats the paper, which is beneficial to the subsequent handkerchief paper production process.

[0006] To solve the above-mentioned technical problems, this utility model provides an unwinding device for handkerchief paper production, including a device base, an unwinding mechanism on the device base, and two symmetrically arranged mounting plates. A clamping assembly for placing the paper roll is provided between the two mounting plates. A guide rod is fixed to one side of the clamping assembly, a heating assembly is provided to one side of the guide rod, and a drive roller for guiding the paper is provided to one side of the heating assembly. The clamping assembly for placing the paper roll, the guide rod, the heating assembly, and the drive roller for guiding the paper constitute an unwinding device for processing handkerchief paper. This unwinding device has the ability to complete the basic actions in the handkerchief paper unwinding production process, stably placing the paper roll and gradually guiding the paper into subsequent production stages.

[0007] The clamping assembly includes two expansion clamps positioned between mounting plates. One expansion clamp is mounted on one side of the mounting plate via a drive mechanism, while the other expansion clamp is slidably positioned between the two mounting plates via a sliding assembly. The two expansion clamps securely hold the paper roll, ensuring its stability during unwinding. This design, with one expansion clamp mounted via a drive mechanism and the other slidably positioned via a sliding assembly, accommodates paper rolls of different sizes and allows for flexible adjustments during installation, ensuring accurate and reliable paper roll installation.

[0008] The driving component includes a first geared motor, the output shaft of which is connected to the expansion clamp via a flange. The first geared motor, connected to the expansion clamp via the flange, provides a stable power output to the expansion clamp, allowing it to rotate according to production requirements and thus drive the paper roll for unwinding. This not only ensures the stability and reliability of power transmission but also helps improve the smoothness of the unwinding process.

[0009] The sliding assembly includes a groove mounted on the base of the device, a slider that slides within the groove, a fixed base fixed to the slider, and a rotating shaft rotatably mounted on the fixed base. The rotating shaft is connected to the expansion clamp via a flange. By sliding the slider within the groove, the fixed base can slide along the groove, thereby moving the connected expansion clamp. This allows for convenient and quick adjustment of the expansion clamp's position to accommodate the installation requirements of paper rolls of different specifications, improving the versatility and applicability of the unwinding device.

[0010] An electro-hydraulic push rod is fixed on one side of the slide to drive the slider movement. The electro-hydraulic push rod can precisely control the movement of the slider, thereby more accurately adjusting the distance between the two expansion clamps, ensuring that the clamping force on the paper roll is appropriate, avoiding the paper roll shaking due to excessive loose clamping or damage to the paper roll due to excessive tight clamping, and improving the operating accuracy and stability of the unwinding device.

[0011] The heating assembly includes a guide groove on a mounting plate, within which a fixed shaft slides. Both ends of the fixed shaft are connected to electric cylinders for controlling its lifting and lowering movement. By controlling the lifting and lowering movement of the fixed shaft within the guide groove using the electric cylinders, the heating assembly can flexibly adjust the height of the heating element according to the actual position of the paper and production needs, ensuring the uniformity and stability of the heating effect and meeting the paper heating requirements of different production processes.

[0012] A heating element for heating the paper is rotatably mounted on a fixed shaft via bearings. This rotatable mounting of the heating element on the fixed shaft ensures its free rotation, allowing for more even heat distribution and preventing localized overheating or underheating. Furthermore, this rotating connection method helps reduce wear on the heating element during operation, extending its service life.

[0013] A second geared motor for driving the drive roller to rotate is connected to the side wall of the mounting plate. By mounting the second geared motor on the side wall of the mounting plate and driving the drive roller to rotate, a stable power can be provided to the drive roller, allowing the drive roller to move the paper forward at the speed and force required for production. This ensures the smoothness and stability of the paper output, which is beneficial to improving the overall efficiency and quality of handkerchief paper production.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. By setting up a clamping assembly including two expansion clamps, one of which is installed by a drive component and the other is slidably set by a sliding component, the paper roll can be placed and fixed in a convenient manner while adapting to the installation requirements of paper rolls of different sizes.

[0016] 2. The sliding block is driven by the electric hydraulic push rod in the sliding assembly to slide in the slide groove, which in turn drives the connected expansion clamp to move, so that the paper roll installation position can be flexibly adjusted, enhancing the adaptability of the device to paper rolls of different specifications.

[0017] 3. The electric cylinder in the heating assembly controls the fixed shaft to move up and down in the guide groove. The fixed shaft is equipped with a heating element, which can heat the paper and meet the specific process requirements for heating paper in the production of handkerchief paper.

[0018] 4. A second geared motor is connected to the side wall of the mounting plate to drive the drive roller to rotate, which can stably export paper from the paper roll and ensure the smooth operation of the handkerchief paper production process. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-5 As shown: This embodiment provides an unwinding device for handkerchief paper production, including a device base 10. An unwinding mechanism 20 is provided on the device base 10. The unwinding mechanism 20 includes two symmetrically arranged mounting plates 21. A clamping assembly 22 for placing the paper roll is provided between the two mounting plates 21. A guide rod 23 is fixed to one side of the clamping assembly 22, a heating assembly 24 is provided to one side of the guide rod 23, and a drive roller 25 for guiding the paper out is provided to one side of the heating assembly 24. By providing the unwinding mechanism 20 on the device base 10, the unwinding mechanism 20 includes two symmetrically arranged mounting plates 21. The clamping assembly 22 for placing the paper roll is provided between the two mounting plates 21 to ensure stable placement of the paper roll; the guide rod 23 is provided to one side of the clamping assembly 22 to guide the paper in subsequent components; the heating assembly 24 is provided to one side of the guide rod 23 to heat the paper and improve its performance; and the drive roller 25 for guiding the paper out is provided to one side of the heating assembly 24 to achieve smooth paper outflow.

[0027] As Figure 1 , Figure 2 and Figure 3As shown, the clamping assembly 22 includes two expansion clamps 221 disposed between mounting plates 21. One expansion clamp 221 is mounted on one side of the mounting plate 21 via a drive component, and the other expansion clamp 221 is slidably disposed between the two mounting plates 21 via a sliding assembly 225. The paper roll is clamped and fixed by the two expansion clamps 221. The distance between the two expansion clamps 221 is adjusted according to the length of the paper roll to accommodate paper rolls of different sizes. Moreover, one of the expansion clamps 221 is connected to a first reduction motor 222, which provides power for the paper roll to rotate. As the expansion clamp 221 inflates the paper roll, it drives the paper roll to rotate and unwind.

[0028] like Figure 1 As shown: The driving component includes a first geared motor 222, and the output shaft 223 of the first geared motor 222 is connected to the expansion chuck 221 via a flange. The connection between the output shaft 223 of the first geared motor 222 and the expansion chuck 221 via a flange provides a stable structure and effectively transmits power, enabling the first geared motor 222 to stably drive the expansion chuck 221 to rotate, thereby driving the paper roll to rotate.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown: The sliding assembly 225 includes a slide groove 2251 disposed on the device base 10, a slider 2252 slidably disposed within the slide groove 2251, a fixed base 2253 fixedly disposed on the slider 2252, and a rotating shaft 2254 rotatably disposed on the fixed base 2253. The rotating shaft 2254 is connected to the expansion clamp 221 via a flange. The sliding of the slider 2252 within the slide groove 2251 can drive the expansion clamp 221 to move, thereby adjusting the distance between the two expansion clamps 221 to accommodate paper rolls of different lengths.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown: An electro-hydraulic push rod 2255 for driving the slider 2252 to move is fixed on one side of the slide groove 2251. By controlling the extension and retraction of the electro-hydraulic push rod 2255, the slider 2252 is pushed to slide within the slide groove 2251, thereby precisely adjusting the position of the expansion chuck 221, achieving accurate adjustment of the position of the expansion chuck 221, and improving the convenience and accuracy of operation.

[0031] like Figure 1 , Figure 2 and Figure 5As shown, the heating assembly 24 includes a guide groove 241 on the mounting plate 21. A fixed shaft 242 is slidably disposed within the guide groove 241. Electric cylinders 243 are connected to both ends of the fixed shaft 242 to control its lifting and lowering movement. The extension and retraction of the electric cylinders 243 control the lifting and lowering of the fixed shaft 242 within the guide groove 241, thereby adjusting the height of the heating element 244 to accommodate the heating requirements of papers of different thicknesses. Simultaneously, raising the height of the heating element 244 also helps to tighten the paper on the equipment, preventing wrinkles. Furthermore, when the paper is being conveyed on the equipment, the electric cylinders 243 flexibly adjust the vertical height of the heating element 244 according to the paper's conveying speed, alleviating paper tension.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown: A heating element 244 for heating paper is rotatably mounted on a fixed shaft 242 via a bearing. The bearing allows the heating element 244 to rotate freely, and as the paper passes through, the heating element 244 rotates continuously, achieving uniform heating of all parts of the paper.

[0033] like Figure 3 As shown: A second geared motor 26 for driving the drive roller 25 to rotate is connected to the side wall of the mounting plate 21. When the second geared motor 26 is running, it drives the drive roller 25 to rotate, thereby smoothly exporting the paper that has been heated and treated.

[0034] The method of using this utility model is as follows: First, according to the size of the paper roll, activate the electric hydraulic push rod 2255. The electric hydraulic push rod 2255 pushes the slider 2252 to slide within the groove 2251. The slider 2252 drives the fixed base 2253 to move, adjusting the distance between the two expansion clamps 221. Then, place the paper roll over the outside of the two expansion clamps 221. Next, activate the electric hydraulic push rod 2255 again, causing the slider 2252 to move in the opposite direction, driving the expansion clamps 221 closer until the expansion clamps 221 insert into the inner hole of the paper roll and tighten the paper roll. Then, place the paper sequentially on the guide rod 23, and... On the heating assembly 24 and drive roller 25, the first reduction motor 222 and the second reduction motor 26 are then started. The output shaft 223 of the first reduction motor 222 drives one of the expansion chucks 221 to rotate through the flange. As the expansion chuck 221 tightens the paper roll, it drives the paper roll to rotate and unwind. Meanwhile, the second reduction motor 26 drives the drive roller 25 to rotate. The drive roller 25 smoothly delivers the paper to the subsequent handkerchief paper production process. During this period, the paper passes through the heating element 244, which heats the paper evenly, making it more suitable for the subsequent handkerchief paper production process after heating.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
