Technical Field
[0001] This utility model relates to the field of rewinding machine technology, specifically to a receiving device for a dual-axis center slitting rewinding machine. Background Technology
[0002] A rewinding machine is a common production equipment, mainly used to rewind large rolls of raw materials into smaller rolls, typically used for packaging, printing, or other subsequent processing. The working principle of a rewinding machine is to control the tension of the roll material and rewind the large rolls of raw materials into specified specifications or lengths through steps such as slitting, cutting, and rewinding. Rewinding machines play an important role in many industries, especially in the processing of materials such as paper, film, aluminum foil, and tape. With the development of technology, the performance of rewinding machines has gradually improved, the degree of automation and intelligence has been continuously enhanced, and energy efficiency and environmental protection have been improved. Future rewinding machines will develop towards a more efficient, more precise, and more environmentally friendly direction.
[0003] During material conveying and receiving, a certain tension needs to be applied. Different materials require different tensions. In general rewinding machines, it is difficult to effectively adjust the tension, resulting in excessive or insufficient tension on the material. Excessive tension can easily damage the material, while insufficient tension can cause wrinkles or slippage during winding. After winding, general rewinding machines require a lot of time to remove the rolled material and install the winding roller, increasing downtime and significantly reducing receiving efficiency. To address these issues, a receiving device for a dual-axis center slitting rewinding machine is proposed. Utility Model Content

This device solves the problem that current materials require a certain tension during conveying and receiving, and different materials require different tensions. Conventional rewinders often struggle to effectively adjust the tension, leading to excessive or insufficient tension on the material. Excessive tension can damage the material, while insufficient tension can cause wrinkles or slippage during winding. Furthermore, conventional rewinders require significant time to remove the rolled material and install the take-up rollers after winding, increasing downtime and significantly reducing receiving efficiency.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0018] Reference Figure 1-3 As shown, a receiving device for a dual-axis center slitting and rewinding machine includes a receiving platform 1. Support legs 2 are fixedly connected to the four lower corners of the receiving platform 1. A front mounting plate 3 is fixedly connected to the upper front end of the receiving platform 1. A control panel 4 is fixedly connected to the left front end of the front mounting plate 3 for convenient control of various electrical components. Several first adjustment grooves 5 are opened through the center of the front side of the front mounting plate 3. Guide rods 6 are fixedly connected to the upper and lower sides inside the first adjustment grooves 5. A first slider 7 is slidably connected to the surface of the guide rods 6.
[0019] Specifically, a rear mounting plate 8 is fixedly connected to the upper rear end of the receiving platform 1. A slitting shaft 9 is fixedly connected to the front left end of the rear mounting plate 8. Several cutters 10 are engaged on the surface of the slitting shaft 9 to effectively cut the material. Several second adjustment grooves 11 are opened through the center of the rear side of the rear mounting plate 8. A second slider 12 is slidably connected inside the second adjustment groove 11. An adjustment threaded rod 13 is threadedly connected to the upper side of the second adjustment groove 11. A rotating support 14 is fixedly installed inside the lower side of the second adjustment groove 11. The lower end of the adjustment threaded rod 13 passes through the upper side of the second slider 12 and is rotatably connected to the inside of the rotating support 14. The upper end of the adjustment threaded rod 13 passes through the inside of the second adjustment groove 11 and is fixedly connected to a knob 15. The position of the second slider 12 and the tension roller 16 can be changed by rotating the knob 15, thereby changing the material conveying path and angle to achieve the purpose of tension adjustment. The front side of the second slider 12 is rotatably connected to the tension roller 16. The front side of the tension roller 16 is rotatably connected to the rear side of the first slider 7.
[0020] Specifically, two sets of take-up motors 17 are fixedly installed on the front right side of the front mounting plate 3. The output end of the take-up motor 17 passes through the front side of the front mounting plate 3 and is fixedly connected to a connecting cylinder 18. An electromagnet 19 is fixedly connected inside the connecting cylinder 18. By connecting and disconnecting the power, the magnetic force of the electromagnet 19 can be changed, so that the rectangular metal connecting rod 24 is connected to the connecting cylinder 18, driving the take-up roller 22 to rotate. Two sets of shaft-changing motors 20 are fixedly installed on the rear right side of the rear mounting plate 8. The output end of the shaft-changing motor 20 passes through the rear side of the rear mounting plate 8. A connecting plate 21 is fixedly connected to the front of the connecting plate 21. Both the left and right ends of the front side of the connecting plate 21 are rotatably connected to the take-up roller 22. A groove 23 is provided at the center of the front side of the take-up roller 22. A rectangular metal connecting rod 24 is slidably connected to the front end of the groove 23. A spring 25 is fixedly connected at the center of the rear side of the rectangular metal connecting rod 24. The end of the spring 25 is fixedly connected to the rear side of the groove 23. After the electromagnet 19 loses its magnetic force, the rectangular metal connecting rod 24 can be pulled back into the groove 23, which facilitates the replacement of the take-up roller 22.
[0021] Working principle: Before receiving the material, according to the properties of the material being processed, first rotate each knob 15 and adjust the threaded rod 13 to adjust the height of the second slider 12 and each tension roller 16 to a suitable position. Changing the length and angle of the material conveying path can effectively apply different tensions to the material. After the tension is adjusted, the material is conveyed from the left end to the slitting shaft 9 and cut into a specified width by the cutter 10. After the cut material passes over the surface of each tension roller 16, it is rolled up on the surface of the take-up rollers 22 at both ends. After the material is rolled up, the electromagnet 19 will... When the power is cut off and the magnetic force is lost, the rectangular metal connecting rod 24 retracts into the slide groove 23 under the elastic force of the spring 25. The shaft-changing motor 20 drives the connecting plate 21 to rotate, rotating the take-up roller 22 with the material roll to the right end of the take-up platform 1 to remove the material roll. At the same time, the take-up roller 22 without the material roll rotates to the rear side of the connecting cylinder 18. The electromagnet 19 is energized to generate magnetic force, which pulls the rectangular metal connecting rod 24 into the connecting cylinder 18. The take-up motor 17 drives the connecting cylinder 18 and the take-up roller 22 to rotate for take-up, effectively improving the take-up efficiency.
