Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting machine technology, specifically to a waste material winding device for a die-cutting machine. Background Technology
[0002] In the field of waste disposal for die-cutting machines, traditional waste rewinding devices generally suffer from limited functionality and poor adaptability. Existing equipment often uses fixed-structure rewinding rollers, making it difficult to flexibly adjust the peeling angle and adapt to the rewinding needs of waste materials of different materials and thicknesses. This easily leads to quality defects such as tearing and wrinkling during the peeling process. Furthermore, most devices lack an effective tension adaptive mechanism. When the waste conveying speed changes or the material properties fluctuate, they cannot automatically adjust the rewinding tension, easily causing the waste to accumulate too loosely or break due to excessive tightness, even leading to equipment failure. As the die-cutting industry continues to demand greater production flexibility and efficiency, existing waste rewinding devices can no longer meet the diverse actual production needs.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0018] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] See Figures 1 to 4 As shown, the structure of this utility model is as follows: a waste material winding device for a die-cutting machine, including a frame 1, a waste material winding roller 2 rotatably mounted on the frame 1, and a motor 3 that is drivenly connected to the waste material winding roller 2. A clearance groove 4 is provided on the frame 1 along the conveying direction, and slide rails 5 are provided on both sides of the clearance groove 4. A mounting seat 6 is slidably connected on the slide rails 5. A position adjustment mechanism 7 for adjusting the position of the mounting seat 6 is provided on the frame 1. A crossbar 8 with one end passing through the clearance groove 4 is provided on the mounting seat 6. A guide rod 9 is slidably provided on the crossbar 8. An intermediate roller 10 is rotatably mounted on one end of the guide rod 9. A tension adjustment mechanism 11 for adjusting the tension of the intermediate roller 10 is provided on the crossbar 8. Specifically, during the operation of the die-cutting machine, after the waste material is produced from the die-cutting station, it is guided by the intermediate roller 10 and finally wound onto the waste material winding roller 2 to complete the winding. The clearance groove 4 on the frame 1 provides movement space for the mounting base 6 and the crossbar 8. When it is necessary to adjust the waste stripping angle, the position adjustment mechanism 7 can drive the mounting base 6 to slide laterally along the slide rail 5, and the crossbar 8 moves accordingly, thereby driving the transition roller 10 to change position, realizing the adjustment of the waste stripping angle, so as to strip the waste from the strip at a more reasonable angle, avoiding adverse effects such as product sticking to waste or waste breaking during the waste stripping process. During the winding process, when tension fluctuations occur due to changes in the thickness of the waste on the waste take-up roller 2, the tension adjustment mechanism 11 adjusts the pressure of the transition roller 10 on the waste, thereby maintaining a stable winding tension. By flexibly adjusting the stripping angle and tension, it can adapt to the characteristics of different waste materials, effectively avoiding problems such as breakage and wrinkles of waste materials during winding, and improving the quality and efficiency of waste material winding.
[0020] like Figure 2As shown, the position adjustment mechanism 7 includes a lead screw nut 701 fixedly mounted on the mounting base 6, and a lead screw 702 rotatably mounted on the frame 1 and threadedly connected to the lead screw nut 701. A handwheel 703 is mounted on one end of the lead screw 702. Specifically, when the handwheel 703 is rotated, the handwheel 703 drives the lead screw 702 to rotate. Through the threaded engagement between the lead screw 702 and the lead screw nut 701, the rotational motion of the lead screw 702 is converted into the linear motion of the lead screw nut 701, thereby driving the mounting base 6 to slide along the slide rail 5. The position of the mounting base 6 can be easily and accurately adjusted, thereby realizing the adjustment of the lateral position of the transition roller 10.
[0021] like Figure 3 As shown, the tension adjustment mechanism 11 includes a bracket 1101. One end of the guide rod 9 passes through the bracket 1101 and is threadedly connected to an adjusting nut 1104. A spring 1102 is provided inside the bracket 1101. One end of the spring 1102 abuts against a retaining ring 1103 provided on the guide rod 9, and the other end of the spring 1102 abuts against the bracket 1101. Specifically, during the waste material winding process, the transition roller 10 is in direct contact with the waste material. When the thickness of the waste material changes or the conveying speed changes, causing tension fluctuations, the guide rod 9 will slide on the crossbar 8. At this time, since one end of the spring 1102 abuts against the retaining ring 1103 on the guide rod 9 and the other end contacts the bracket 1101, when the guide rod 9 slides, the spring 1102 will be compressed or stretched. The elastic force generated by the compression or stretching of the spring 1102 will act on the guide rod 9 through the retaining ring 1103, and then be transmitted to the transition roller 10. Through the elastic adaptive capability of the spring 1102, the pressure of the transition roller 10 on the waste material is automatically adjusted, realizing the dynamic adjustment of the winding tension. At the same time, the adjusting nut 1104 is connected to the guide rod 9 by a thread and moves along the axial direction of the guide rod 9 when rotating, thereby compressing or releasing the spring 1102 in the bracket 1101, thereby precisely adjusting the preload of the spring 1102, so that the pressure of the transition roller 10 on the waste material can be flexibly changed according to the characteristics of the waste material, thickness and other characteristics. It can increase the tension to avoid slippage when processing thick and hard waste materials, and reduce the tension to prevent breakage when processing thin and soft materials, realizing the fine control and stable adjustment of tension during the winding process.
[0022] like Figure 3As shown, both the support 1101 and the crossbar 8 are equipped with linear bearings 12 that slide with the guide rod 9. Specifically, when the guide rod 9 needs to slide on the crossbar 8 or the support 1101, the rolling elements inside the linear bearing 12, such as balls, will roll between the inner and outer rings of the bearing, transforming the original sliding friction between the guide rod 9 and the support 1101 and the crossbar 8 into rolling friction. This change in friction greatly reduces the resistance encountered by the guide rod 9 when sliding, allowing the guide rod 9 to slide more smoothly and flexibly on the support 1101 and the crossbar 8. Its function is to reduce the friction during the sliding process of the guide rod 9, improve the sensitivity and adjustment accuracy of the guide rod 9, reduce component wear, extend the service life of the equipment, and at the same time ensure that the tension adjustment mechanism 11 and the position adjustment mechanism 7 of the transition roller 10 can respond quickly and accurately to changes in the tension and position of the waste material.
[0023] like Figure 2 As shown, the output end of the motor 3 is provided with a first U-shaped pulley 301, and one end of the waste collection roller 2 is provided with a second U-shaped pulley 201. An O-shaped belt 13 is fitted on the first U-shaped pulley 301 and the second U-shaped pulley 201. A tensioner 14 that abuts against the O-shaped belt 13 is provided on the frame 1. Specifically, the groove design of the U-shaped pulley can adjust the tension of the O-shaped belt 13 by adjusting the tension of the O-shaped belt 13 through the tensioner 14 to change the friction threshold. When the waste tension fluctuates due to changes in material thickness and winding speed, the O-shaped belt 13 and the first U-shaped pulley 301 and the second U-shaped pulley 201 can automatically adjust the tension within a certain range by slipping.
[0024] In practical use, during die-cutting operations, such as Figure 4 As shown, the waste material produced is output from the die-cutting station, passes around the transition roller 10, and is gradually wound onto the waste collection roller 2 for winding under the rotational traction of the waste collection roller 2. During the winding process, if the waste material is found to accumulate, wrinkle, or tear, the position adjustment mechanism 7 can drive the mounting base 6 to slide on the slide rail 5, changing the lateral position of the transition roller 10, thereby adjusting the waste material peeling angle. For example, if the waste material sticks to the die-cutting blade and is difficult to peel off, the peeling angle is increased to allow the waste material to leave the die-cutting area more smoothly; if the waste material is thin and easily broken, the peeling angle is decreased to reduce the tension on the waste material. When the thickness of the waste material on the waste collection roller 2 changes, causing fluctuations in the winding tension, the tension adjustment mechanism 11 automatically responds to the tension changes of the waste material, ensuring that the winding tightness is appropriate and reducing the adhesion of waste material to the product and the breakage of the waste material.
[0025] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
