Description

Technical Field

[0001] This utility model relates to the field of paper towel production, and in particular to an adjustable-spacing roller-type folding guide device. Background Technology

[0002] In the tissue paper production process, the folding guide device is one of the key pieces of equipment affecting product quality and production efficiency. Traditional roller-type folding devices typically use a fixed-gap roller structure, which is difficult to adapt to the production needs of tissue paper with different thicknesses, materials, or folding process requirements. When tissue paper requires multi-layer composite folding, the fixed-gap rollers are prone to uneven tissue paper tension, folding misalignment, or paper jams, requiring frequent machine stops for adjustment, which seriously affects production continuity. In addition, existing adjustable devices mostly rely on manual adjustment, which is complex to operate and lacks precision, making it difficult to meet the demands of modern production lines for efficient, precise, and automated control. Therefore, developing a folding guide device that can quickly and accurately adjust the roller spacing and adapt to diverse production needs has become an urgent technical problem to be solved in the tissue paper production industry.

Both the adjustable rollers and the movable guide roller can be adjusted in the vertical direction.

[0005] Furthermore, each set of adjustable rollers includes a pair of mounting frames disposed on the top surface of the frame; wherein, a drive cylinder is vertically mounted on the top of the mounting frame; a guide rail is disposed on the inner side of the mounting frame, a bearing seat is slidably disposed on the guide rail, the top surface of the bearing seat is fixed on the output shaft of the drive cylinder, and one roller is mounted on the inner side of the bearing seat of each pair of mounting frames.

[0006] Furthermore, a transmission structure is provided on the outer side of the bearing seat of the adjustable roller, and the transmission structure is connected to a drive motor, which is located at the bottom of the frame.

[0007] Furthermore, two fixed guide rollers are provided, each located on one side of the adjustable roller.

[0008] Furthermore, the movable guide roller includes a vertically arranged slot frame, which is located in the middle of the frame body; the slot frame has a vertically opened slot, and an installation groove is provided on the outer side of the slot; a bearing seat two is slidably fitted in the installation groove, and a roller two is installed in the bearing seat two.

[0009] Furthermore, a tension spring is provided on the top of the bearing housing two, and the tension spring is fixed to the top of the slot frame.

[0010] Furthermore, a control box is provided on one side of the frame, and a raw material roller is also provided on the top surface of the frame.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This invention provides an adjustable-spacing roller-type folding guide device, comprising a frame 1, with multiple adjustable rollers 2 arranged on the top surface of the frame 1. A fixed guide roller 3 and a movable guide roller 4 are arranged between two sets of adjustable rollers 2. Both the adjustable rollers 2 and the movable guide roller 4 are adjustable in the vertical direction. The frame 1 serves as an integral support structure; the adjustable rollers 2 and the movable guide roller 4 enable the device to dynamically adjust the transmission path according to the thickness of the tissue paper.

[0020] Each set of adjustable rollers 2 includes a pair of mounting frames 201 disposed on the top surface of the frame 1; wherein, a drive cylinder 202 is vertically mounted on the top of the mounting frame 201; a guide rail 203 is disposed on the inner side of the mounting frame 201, and a bearing seat 204 is slidably disposed on the guide rail 203, the top surface of the bearing seat 204 being fixed to the output shaft of the drive cylinder 202, and a roller 205 is mounted on the inner side of the bearing seat 204 of each pair of mounting frames 201. The drive cylinder 202 pushes the bearing seat 204 to move vertically along the guide rail 203 by air pressure, thereby driving the roller 205 to rise and fall; the linear guiding effect of the guide rail 203 ensures that there is no swaying during the roller adjustment process.

[0021] A transmission structure 206 is provided on the outer side of the bearing seat 204 of the adjustable roller 2. The transmission structure 206 is connected to a drive motor 207, which is located at the bottom of the frame 1. The drive motor 207 transmits power to the roller 205 through the transmission structure 206, preferably through a synchronous belt drive or chain drive, thereby realizing the rotation of the roller.

[0022] Two fixed guide rollers 3 are provided, each located on one side of the adjustable roller 2. The fixed guide rollers 3 are fixed in position by a rigid mounting frame, providing a basic transport path for the paper towel; the double roller layout forms a stable clamping channel, preventing the paper towel from shifting laterally during adjustment. The movable guide roller 4 includes a vertically arranged slot frame 401, which is located in the middle of the frame 1; the slot frame 401 has a vertically opened slot 402, and an installation groove 403 is provided on the outer side of the slot 402. A bearing seat 404 is slidably fitted in the installation groove 403, and a roller 405 is installed in the bearing seat 404. The vertical slot 402 of the slot frame 401 provides a sliding track for the bearing seat 404, allowing the roller 405 to adaptively adjust its height according to the paper towel tension; the clamping design of the installation groove 403 prevents the bearing seat 404 from falling out, ensuring a safe and reliable adjustment process. A tension spring 406 is installed on the top of the bearing seat 404. The tension spring 406 is fixed to the top of the slot frame 401. The tension spring 406 provides an upward pulling force to the roller 405 through elastic tension, compensating for the tension fluctuation of the paper towel. The spring preload is adjustable, allowing the device to adapt to the tension control requirements of different paper towel materials. A control box 5 is installed on one side of the frame 1. The control box 5 integrates a cylinder solenoid valve, a motor frequency converter, and a PLC controller to realize the digital setting of adjustment parameters. A raw material roller 6 is also installed on the top surface of the frame 1, which serves as the initial unwinding mechanism for the paper towel roll. A guide frame 7 is installed at the front end of the top surface of the frame 1. The guide frame 7 smoothly introduces the paper towel into the roller assembly, avoiding wrinkles in the initial section.

However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
