Description

Technical Field

[0001] This utility model relates to the technical field of paper roller support frame for hand towel processing, and particularly to a paper roller support frame for hand towel processing. Background Technology

[0002] Hand towel processing is the process of transforming raw paper into finished hand towels through a series of mechanical and chemical treatments. This process includes steps such as raw paper preparation, slitting, folding, and packaging, ultimately producing hand towel products that meet specific quality standards and usage requirements.

[0003] In the preparation stage of paper towel processing, the semi-finished paper rolls along with the shaft need to be loaded onto the paper roll support frame. Then, one end of the paper roll is pulled out and passes around the fixed roller inside the support frame to connect with the subsequent slitting equipment, thus completing the raw material transportation.

[0004] In the existing paper roll support frame, after the paper roll is installed inside the support frame, the conveying begins. However, the existing paper roll lacks a limit for the paper roll, which often causes deviation during the long-term rotation of the paper roll during the conveying process. This can lead to defects in subsequent processing. Sometimes, the deviation of the paper roll can also cause uneven stress on the paper, resulting in tearing and affecting processing, making it inconvenient to use. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a paper roller support frame for paper towel processing, including a base plate 1. A limiting component 4 is provided on the upper surface of the base plate 1. A rotating shaft 5 is provided above the limiting component 4. A paper roll 3 is provided on the outer surface of the rotating shaft 5. Two fixing boxes 2 are installed on the upper surface of the base plate 1. A tensioning component 6 is provided between the two fixing boxes 2.

[0031] The limiting component 4 includes two fixing brackets 401 fixedly installed on the upper surface of the substrate 1. Two rotating shafts 402 are movably connected to the outer surface of the fixing brackets 401. A rotating plate 403 is provided on the outer surface of the rotating shafts 402. Two abutment plates 404 are slidably provided on the upper surface of the substrate 1. A first worm gear 407 is fixedly connected to the bottom outer surface of each of the two rotating shafts 402. A transmission shaft 406 is movably connected inside the substrate 1. A first worm 408 that meshes with the first worm gear 407 is fixedly connected to the outer surfaces of both ends of the transmission shaft 406.

[0032] Specifically, the top of the fixed frame 401 is provided with an arc-shaped groove that cooperates with the rotating shaft 5. The outer surfaces of the fixed frame 401, the rotating plate 403 and the abutment plate 404 are all provided with the same inclined surface. The arc-shaped groove facilitates the loading of the rotating shaft 5 onto the top of the fixed frame 401. The inclined surface allows the rotating shaft 5 to roll to the top of the fixed frame 401 when the paper roll 3 is rolled.

[0033] Specifically, two limiting sliders 405 are fixedly connected to the bottom of the abutment plate 404, and a groove is provided on the upper surface of the base plate 1 to cooperate with the limiting sliders 405. The cooperation between the limiting sliders 405 and the groove facilitates the lateral movement of the limiting abutment plate 404.

[0034] Furthermore, by rotating the transmission shaft 406 with other tools, the transmission shaft 406, through the cooperation of the first worm gear 408 and the first worm wheel 407, drives the two rotating shafts 402 to rotate, thereby driving the two rotating plates 403 to rotate inward synchronously. The rotating plates 403 drive the abutment plate 404 to move inward, so that the abutment plate 404 abuts against the side of the paper roll 3, thereby achieving a limiting effect and preventing the paper roll 3 from shifting during long-term rotation.

[0035] Example 2

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The tensioning component 6 includes a threaded rod 604 that is movably connected to the inside of the fixed box 2 via a bearing. A threaded sleeve 612 is engaged with the outer surface of the threaded rod 604. A lifting plate 603 is fixedly connected to the outer surface of the threaded sleeve 612. An arc-shaped plate 601 is provided on the upper surface of the lifting plate 603.

[0037] Specifically, a rotating rod 607 is movably connected to the inside of the substrate 1 via bearings. Second worm gears 606 are fixedly connected to the outer surfaces of both ends of the rotating rod 607. A second worm wheel 605, cooperating with the second worm gear 606, is fixedly connected to the bottom outer surface of the threaded rod 604. A reduction motor 608 is fixedly connected inside the substrate 1. The output end of the reduction motor 608 is fixedly connected to one end of the rotating rod 607. The reduction motor 608 drives the rotating rod 607 to rotate, thereby driving the two second worm wheels 605 to rotate synchronously via the second worm gear 606. The direction of the threads on the outer surfaces of the two threaded rods 604 ensures that when the two second worm wheels 605 drive the two threaded rods 604 to rotate synchronously, the two threaded sleeves 612 can drive the lifting plate 603 to rise and fall synchronously on the surface of the threaded rod 604.

[0038] Specifically, two plug-in plates 602 are fixedly connected to the lower surface of the arc plate 601. The outer surfaces of the two fixed boxes 2 are provided with limiting grooves that cooperate with the plug-in plates 602. The outer surfaces of the two fixed boxes 2 are provided with rectangular openings that cooperate with the lifting plate 603. Through the cooperation of the plug-in plates 602 and the limiting grooves, the lifting and lowering of the arc plate 601 is limited, preventing the limiting plate from rotating. The rectangular openings facilitate the lifting and lowering of the lifting plate 603 and also serve as limiting mechanisms.

[0039] Specifically, two fixing blocks 614 are fixedly connected to the lower surface of the curved plate 601. A spring 613 is fixedly connected between the lower surface of the fixing block 614 and the upper surface of the lifting plate 603. A plug rod 610 is fixedly connected to the lower surface of the fixing block 614. Two pressure sensors 611 are installed inside the lifting plate 603. The bottom end of the plug rod 610 passes through the upper surface of the lifting plate 603 and abuts against the upper surface of the pressure sensor 611. Through the cooperation of the fixing block 614 and the spring 613, the lifting plate 603 can drive the curved plate 601 to move. Through the cooperation of the plug plate 602 and the pressure sensor 611, it is convenient to control the degree of tension of the paper driven by the curved plate 601.

[0040] Specifically, a number of insert blocks 609 are fixedly connected to the lower surface of the arc plate 601, and the inside of the lifting plate 603 is provided with through holes that cooperate with the insert blocks 609. Through the cooperation of the insert blocks 609 and the through holes, the lifting and lowering of the arc plate 601 relative to the lifting plate 603 is limited.

[0041] Furthermore, the geared motor 608 drives the two second worm gears 606 to rotate via the rotating rod 607. The cooperation between the second worm gears 606 and the second worm wheel 605 drives the two threaded rods 604 to rotate synchronously, thereby causing the threaded sleeve 612 to drive the lifting plate 603 to rise and fall. The lifting plate 603 drives the arc plate 601 to rise and fall via the spring 613 and the fixing block 614, causing the arc plate 601 to tighten the paper, thereby achieving paper tensioning.

[0042] Working principle: When feeding paper roll 3 during the paper towel processing, the rotating shaft 5 is inserted inside the paper roll 3, and then the paper roll 3 rolls to one side of the base plate 1. The rotating plate 403, the abutment plate 404, and the inclined surface of the outer surface of the fixing frame 401 push the paper roll 3, thereby moving the paper roll 3 and the fixing frame 401 into the arc-shaped groove at the top of the fixing frame 401, thus loading the paper roll 3. Then, the paper roll 3 is manually adjusted to the center position, and one end of the paper roll 3 is pulled around the upper surface of the arc-shaped plate 601. Then, according to the diameter of the paper roll 3 and the properties of the paper, the tensioning component 6 is adjusted, and the reduction motor 608 is started. The reduction motor 608 drives the two second worm gears 606 to rotate through the rotating rod 607. Through the cooperation of the second worm gears 606 and the second worm wheel 605, the two threaded rods 604 are driven to rotate synchronously, thus... The threaded sleeve 612 drives the lifting plate 603 to rise and fall. The lifting plate 603, through the spring 613 and the fixing block 614, drives the arc plate 601 to rise and fall, causing the arc plate 601 to tighten the paper, thereby achieving paper tensioning. Then, the adjustment of the limiting component 4 begins. The transmission shaft 406 is rotated by other tools, so that the transmission shaft 406, through the cooperation of the first worm 408 and the first worm wheel 407, drives the two rotating shafts 402 to rotate, thereby driving the two rotating plates 403 to rotate inward synchronously. The rotating plates 403 drive the abutment plate 404 to move inward, so that the abutment plate 404 abuts against the side of the paper roll 3, thereby achieving the limiting effect and preventing the paper roll 3 from shifting during long-term rotation. Finally, the step of loading the paper roll 3 onto the paper roller support frame is completed in the paper towel processing process.
