Description

Technical Field

[0001] This utility model relates to the field of paper roll rewinding technology, specifically to an auxiliary rewinding mechanism for paper roll machines. Background Technology

[0002] A roll paper machine is an important finishing piece of equipment after the papermaking machine. It is mainly used to rewind large-format toilet paper from a single layer and cut it into rolls of different sizes for use in folded tissues, napkins, boxed face towels, etc. The roll paper machine plays a crucial role in the paper processing process. Its structural features and functional design allow it to adapt to the cutting of materials with different properties, and it boasts high operating efficiency and precision.

[0003] Common paper winding machines rewind paper at the center of two rewinding shafts, with the paper rising and falling in a fixed slot to ensure even winding. They employ variable frequency speed control motors, allowing speed adjustments based on production needs, improving equipment flexibility and efficiency. Maintaining constant tension during winding prevents paper breakage or loosening due to uneven tension. Equipped with a photoelectric automatic deviation correction system, it ensures accurate paper positioning. Automatic stop devices for material shortages and emergency stop functions ensure timely shutdown in abnormal situations, preventing damage. Pneumatic feeding and unloading mechanisms reduce labor intensity and enhance automation. Suitable for slitting various paper materials, resulting in neater and more aesthetically pleasing finished products. An automatic counting device facilitates real-time monitoring of production progress.

[0004] However, the roller diameter and length of the auxiliary winding mechanism for common paper roll machines are fixed, and only one diameter of roll can be used during winding. This makes the auxiliary winding mechanism for paper roll machines have a limited range of applications and is not convenient for producing rolls of different specifications. In view of this, this application proposes an auxiliary winding mechanism for paper roll machines. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary winding mechanism for paper roll machines, which has the advantages of being adaptable to different specifications of rolls. It solves the problem that common auxiliary winding mechanisms for paper roll machines have fixed roller diameters and lengths, and can only be used with rolls of one diameter during winding, resulting in a limited range of applications and inconvenience for producing rolls of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary winding mechanism for a paper roll machine, including a mounting base, two sliding bases slidably mounted on the top of the mounting base, a control plate and a mounting plate fixedly mounted on the top of the sliding base, and an adjustable inner support assembly rotatably mounted on the side of the mounting plate away from the control plate. The adjustable inner support assembly includes a turntable rotatably mounted on one side of the mounting plate. Four sets of parallel connecting rods are rotatably mounted on the surface of the turntable. Each set of parallel connecting rods consists of two rods. An inner support plate is rotatably mounted on one end of each parallel connecting rod. A baffle is fixedly mounted on one side of the inner support plate. A control connecting rod is rotatably mounted on the side of the parallel connecting rod away from the mounting plate. A control block is rotatably mounted on one end of the control connecting rod. An adjusting rod is provided on one side of the control block. A connecting flange is fixedly installed at one end of the adjusting rod. The connecting flange is fixedly installed on one side of the control block by bolts. The other end of the adjusting rod extends to one side of the control plate.

[0007] Furthermore, two adjusting cylinders are fixedly installed on the side of the control plate near the mounting plate. The movable end of the adjusting cylinder slides through the control plate and is fixedly installed with an adjusting plate. One end of the adjusting rod is fixedly installed on one side of the adjusting plate through a connecting flange.

[0008] Furthermore, a rotating shaft is fixedly installed on one side of one of the turntables, and a driven gear is fixedly installed at one end of the rotating shaft extending between the control plate and the mounting plate.

[0009] Furthermore, a rotary motor is fixedly installed on the side of one of the control plates away from the mounting plate, and a drive gear that meshes with the driven gear is fixedly installed at the output end of the rotary motor.

[0010] Furthermore, two sliders are slidably installed inside the mounting base, and the two sliders are respectively fixedly connected to the bottom of the two sliding bases.

[0011] Furthermore, a double-ended screw is rotatably mounted on the inner side wall of the mounting base. The two ends of the double-ended screw have external threads in opposite directions, and the two sliding bases are respectively threaded to the two ends of the double-ended screw.

[0012] Furthermore, a movable motor is fixedly installed on one side of the mounting base, and the output shaft of the movable motor is fixedly connected to one end of the double-ended screw.

[0013] Compared with the prior art, this utility model provides an auxiliary winding mechanism for a paper roll machine, which has the following advantages: 1. This auxiliary winding mechanism for paper roll machines uses adjustable inner support components on opposite sides of two mounting plates. The control block moves via an adjusting rod, which in turn moves the control linkage, causing the parallel linkage to rotate on the turntable surface. This causes the inner support plate to expand outward, accommodating rolls of different diameters. This solves the problem that common auxiliary winding mechanisms for paper roll machines have fixed roller diameters and lengths, limiting their applicability to only one diameter roll during winding and making them unsuitable for producing rolls of different specifications.

[0014] 2. The auxiliary winding mechanism of this paper roll machine uses a moving motor on one side of the mounting base to drive the double-headed screw to rotate, which in turn drives the two sliders to move synchronously towards the middle or both ends. This allows the two adjustable inner support components to move closer or further away to adapt to rolls of different lengths, thus increasing the applicability of the auxiliary winding mechanism for the paper roll machine.

A control plate 3 and a mounting plate 4 are fixedly mounted on the top of the sliding base 2. An adjustable inner support assembly 5 is rotatably mounted on the side of the mounting plate 4 away from the control plate 3.

[0019] The adjustable inner support assembly 5 includes a turntable 51 rotatably mounted on one side of the mounting plate 4. Four sets of parallel connecting rods 52 are rotatably mounted on the surface of the turntable 51, with two rods in each set. An inner support plate 53 is rotatably mounted at one end of each parallel connecting rod 52. A baffle 531 is fixedly mounted on one side of the inner support plate 53. A control connecting rod 54 is rotatably mounted on the side of the parallel connecting rods 52 away from the mounting plate 4. A control block 55 is rotatably mounted at one end of the control connecting rod 54. With the turntable 51 in a fixed position, moving the control block 55 left or right causes the parallel connecting rods 52 to rotate on the surface of the turntable 51 via the control connecting rod 54, thus expanding or retracting the inner support plate 53 to accommodate reels of different diameters.

[0020] Secondly, an adjusting rod 6 is inserted through one side of the control block 55. A connecting flange 9 is fixedly installed at one end of the adjusting rod 6, and the connecting flange 9 is fixedly installed on one side of the control block 55 by bolts. The other end of the adjusting rod 6 extends to one side of the control plate 3. The adjusting rod 6 drives the control block 55 to move, thereby controlling the outer diameter of the adjustable inner support assembly 5.

[0021] Meanwhile, two adjusting cylinders 7 are fixedly installed on the side of the control plate 3 near the mounting plate 4. The movable end of the adjusting cylinder 7 slides through the control plate 3 and is fixedly installed with an adjusting plate 8. One end of the adjusting rod 6 is fixedly installed on one side of the adjusting plate 8 through a connecting flange 9. The adjusting cylinder 7 drives the adjusting plate 8 to move, which in turn drives the adjusting rod 6 to move, thereby adjusting the outer diameter of the adjustable inner support assembly 5.

[0022] One of the turntables 51 has a rotating shaft 511 fixedly installed on one side, and a driven gear 10 is fixedly installed at one end of the rotating shaft 511 that extends between the control plate 3 and the mounting plate 4.

[0023] Secondly, a rotary motor 11 is fixedly installed on the side of one of the control plates 3 away from the mounting plate 4. A drive gear 12 that meshes with the driven gear 10 is fixedly installed at the output end of the rotary motor 11. The rotary motor 11 drives the drive gear 12 to rotate, which in turn drives the driven gear 10 to rotate, which in turn drives the rotating shaft 511 to rotate, which in turn drives one of the turntables 51 to rotate, which in turn drives the roller mounted on the adjustable inner support assembly 5 to rotate.

[0024] Meanwhile, two sliders 13 are slidably installed inside the mounting base 1, and the two sliders 13 are fixedly connected to the bottom of the two sliding bases 2 respectively.

[0025] The inner wall of the mounting base 1 is rotatably mounted with a double-ended screw 14. The two ends of the double-ended screw 14 are provided with external threads in opposite directions. The two sliding bases 2 are respectively threaded to the two ends of the double-ended screw 14.

[0026] Secondly, a movable motor 15 is fixedly installed on one side of the mounting base 1, and the output shaft of the movable motor 15 is fixedly connected to one end of the double-headed screw 14. The movable motor 15 drives the double-headed screw 14 to rotate, causing the two sliders 13 to move closer or further away synchronously, and causing the two sliding bases 2 to move closer or further away, adjusting the spacing between the two adjustable inner support components 5 to adapt to reels of different lengths.

[0027] In this embodiment, the two sliding bases 2 are moved by the moving motor 15, and the two ends of the roll are fitted onto the surface of the adjustable inner support assembly 5. Then, the adjusting cylinder 7 drives the adjusting rod 6 to move, adjusting the outer diameter of the adjustable inner support assembly 5, and fixing the roll on the surface of the adjustable inner support assembly 5. This increases the range of diameters and lengths of the rolls that can be installed, and improves adaptability.
