Description

Technical Field

[0001] This utility model relates to the field of slitting and rewinding machines, specifically to an adjustable tension slitting and rewinding machine. Background Technology

[0002] Slitting and rewinding machines are key pieces of equipment widely used in the processing of flexible materials such as films, paper, and fabrics. They are mainly used to cut wide materials into several narrow strips according to production needs and rewind them into regular rolls, providing raw materials that meet specifications for subsequent printing, packaging, and lamination processes. They play an important role in the packaging industry, printing industry, and plastics processing.

[0003] The tension adjustment mechanisms in common slitting and rewinding equipment are relatively simple, typically only capable of adjusting tension in a localized or single direction. For example, some equipment can only control the tension in one direction (longitudinal or transverse) of the film, failing to coordinate tension in multiple directions simultaneously. This limitation leads to issues such as vertical slack and uneven tension on both sides of the film during processing, resulting in wrinkles, overstretching, or positional misalignment. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide an adjustable tension slitting and rewinding machine that allows for all-around tension control during adjustment. This solves the technical problem in existing technologies where tension adjustment cannot be coordinated synchronously in multiple directions, leading to easy loosening of the film.

[0005] The objective of this utility model is achieved through the following means:

[0006] An adjustable tension slitting and rewinding machine includes a base, a main control box mounted on one side of the top of the base, and a mounting base on the other side of the upper surface of the base. A raw material rack is mounted at the feeding end of the main control box and the mounting base, and a take-up roller is mounted at the unloading end of the main control box and the mounting base. A slider is inserted inside the mounting base, and a mounting cover is connected to the outside of the slider. An assembly frame is connected to the outer end of the mounting cover. A first motor is inserted inside the mounting cover, and the rotor of the first motor passes through a corresponding position on the assembly frame. A transmission disc is coaxially connected to the outer end of the rotor of the first motor. An insert plate is inserted inside the assembly frame, and an assembly block is connected to the outer end of the insert plate. A tension roller is connected to the outer side of the assembly block. A transmission groove is circumferentially formed inside the transmission disc, and an insert shaft is inserted inside the transmission groove.

[0007] Furthermore, the main control box and the mounting base are equipped with cutting wheels on their inner sides, and the first motor and the mounting cover are connected on both sides by ear plates and bolts, which facilitates the disassembly and assembly of the first motor.

[0008] Furthermore, all the transmission grooves are inclined, the inner ends of the insertion shafts are connected to the corresponding positions on the outer sides of the insertion plates, and the shapes of the insertion plates are all convex, which improves the stability of the insertion plates during movement.

[0009] Furthermore, a through slot is provided inside the mounting base at a position corresponding to the slider, and a second motor is inserted inside the mounting base at a position corresponding to the slider, with the rotor of the second motor passing through the inside of the through slot.

[0010] Furthermore, a lead screw is coaxially connected to the bottom of the rotor of the second motor. The lead screw passes through the interior of the slider and is screwed to it. The bottom end of the lead screw is connected to the bottom of the inner cavity of the through groove through a bearing. The rotation of the lead screw can be driven by the second motor, which can drive the slider to move up and down. This allows the overall up and down position of the three sets of tension rollers to be adjusted, enhancing the flexibility and adaptability of the equipment. It also allows the tension shaft to flexibly change the tension application point and range according to the characteristics of films of different thicknesses and materials, as well as specific processing requirements.

[0011] Furthermore, the outer surface of each tensioning roller is covered with an elastic buffer layer, and the outer surface of the elastic buffer layer is provided with anti-slip texture. The elastic buffer layer is made of silicone material to prevent slippage during the tensioning process.

[0012] The beneficial effects of this invention are as follows: the rotation of the transmission disc driven by the first motor drives the synchronous movement of the insertion shaft and the insertion plate through the transmission groove, thereby enabling the tension rollers to expand synchronously. When the material passes through the three sets of tension rollers along a specific path, the upper tension roller can tension the material vertically during synchronous expansion, while the left and right tension rollers can apply tension to the left and right sides of the material. This all-round tension control avoids the limitation of traditional equipment that can only adjust tension in one direction, preventing problems such as local relaxation, wrinkles, or excessive stretching of the material during processing, and ensuring the flatness and stability of the film during the slitting and rewinding process.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figures 1-7 The specific implementation of the adjustable tension slitting and rewinding machine includes a base 1, a main control box 2 is installed on one side of the top of the base 1, an mounting seat 3 is provided on the other side of the upper surface of the base 1, a raw material rack 4 is installed at the feeding end of the main control box 2 and the mounting seat 3, a winding roller 6 is installed at the unloading end of the main control box 2 and the mounting seat 3, and a slider 7 is inserted inside the mounting seat 3.

[0023] The slider 7 is externally connected to a mounting cover 8, and the outer end of the mounting cover 8 is connected to an assembly frame 9. The first motor 10 is inserted inside the mounting cover 8. The main control box 2 and the mounting base 3 are equipped with cutting wheels 5. The first motor 10 and the two sides of the mounting cover 8 are connected by ear plates and bolts. The rotor of the first motor 10 passes through the corresponding position of the assembly frame 9. The outer end of the rotor of the first motor 10 is coaxially connected to a transmission disk 11.

[0024] An insert plate 14 is inserted inside the assembly frame 9. An assembly block 15 is connected to the outer end of the insert plate 14. A tension roller 16 is connected to the outer side of the assembly block 15. An elastic buffer layer is fitted on the outer surface of the tension roller 16. The outer surface of the elastic buffer layer is provided with anti-slip texture. The elastic buffer layer is made of silicone material. A transmission groove 12 is provided in the circumferential direction inside the transmission disk 11. An insert shaft 13 is inserted inside the transmission groove 12. The transmission groove 12 is inclined. The inner end of the insert shaft 13 is connected to the corresponding position on the outside of the insert plate 14. The insert plate 14 is convex in shape.

[0025] The first motor 10 drives the transmission disc 11 to rotate, which in turn drives the insertion shaft 13 and the insertion plate 14 to move synchronously through the transmission groove 12. This allows the tension roller 16 to expand synchronously. When the material passes through the three sets of tension rollers 16 along a specific path, the upper tension roller 16 can tension the material vertically during synchronous expansion, while the left and right tension rollers 16 can apply tension to the material on the left and right sides. This all-round tension control avoids the limitation of traditional equipment that can only adjust tension in one direction, and prevents the material from becoming loose, wrinkled or overstretched during processing. It ensures the flatness and stability of the film during the slitting and rewinding process.

[0026] A through groove is provided inside the mounting base 3 at a position corresponding to the slider 7. A second motor 17 is inserted inside the mounting base 3 at a position corresponding to the slider 7. The rotor of the second motor 17 passes through the inside of the through groove. A lead screw 18 is coaxially connected to the bottom end of the rotor of the second motor 17. The lead screw 18 passes through the inside of the slider 7 and is screwed to it. The bottom end of the lead screw 18 is connected to the bottom of the inner cavity of the through groove through a bearing.

[0027] This solution uses a first motor 10 to drive the rotation of the transmission disc 11, which in turn drives the synchronous movement of the insertion shaft 13 and the insertion plate 14 through the transmission groove 12. This allows the tension rollers 16 to expand synchronously. When the material passes through the three sets of tension rollers 16 along a specific path, the upper tension roller 16 can tension the material vertically during synchronous expansion, while the left and right tension rollers 16 can apply tension to the left and right sides of the material. This all-round tension control avoids the limitation of traditional equipment that can only adjust tension in one direction, preventing problems such as local relaxation, wrinkles, or overstretching of the material during processing, and ensuring the flatness and stability of the film during the slitting and rewinding process.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
