Description

Technical Field

[0001] This utility model relates to the field of container manufacturing technology, specifically a winding roll with tensioning function. Background Technology

[0002] Various containers are indispensable in our lives, and cans are one of them. In the production of cans and lids, winding devices are used to roll up materials such as metal foil and plastic film for use or storage on the production line. When in use, the core is inserted into the winding drum, and then a nut is typically used to tighten and secure the core. The winding device then drives the winding drum and core to rotate and wind the material. While the structure is simple and the cost is low, the core is secured with a nut, and it needs to be replaced after winding. This replacement process requires repeatedly removing and installing the nut using tools, making core securing cumbersome and affecting ease of use. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a winding drum with tensioning function, including a base 1;

[0021] Base 1: A rotating seat 2 is rotatably connected to the upper part of the base 1. Base 1 provides an installation position for the components above. A support tube 3 is provided on the left side of the rotating seat 2. The rotating seat 2 drives the support tube 3 to rotate. Sliding pins 4 are slidably connected inside the sliding holes on the outer arc surface of the support tube 3. Two horizontally corresponding sliding pins 4 form a group. A support plate 5 is provided at the end of each group of sliding pins 4 away from the support tube 3. Pushing the sliding pins 4 outward causes the support plate 5 to open. A moving shaft 6 is slidably connected inside the rotating seat 2. A moving frame 7 is provided at the right end of the moving shaft 6. A sliding shaft 8 is provided at the end of each sliding pin 4 near the axis of the support tube 3. The sliding shafts 8 are slidably connected to the moving frame 7. The oblique sliding holes of the moving frame 7 interact with the sliding shafts 8. The relative sliding is achieved by tilting the oblique sliding hole from right to left away from the axis of the moving shaft 6. The moving frame 7 slides relative to the sliding shaft 8. The left side of the base 1 is provided with a drive assembly that can drive the moving shaft 6 to move laterally. The inside of the support tube 3 is provided with evenly distributed guide plates 18. The guide plates 18 are all slidably connected to the moving frame 7. The guide plates 18 provide sliding guidance for the moving frame 7. The outer arc surface of the support plate 5 is provided with rubber pads 9. The wound core is inserted into the outside of the three rubber pads 9. The support plate 5 tensions the core through the rubber pads 9. The outer arc surface of the rubber pads 9 is provided with evenly distributed grooves 10 to facilitate the elastic deformation of the rubber pads 9 and increase the friction of the rubber pads 9 on the core.

[0022] The drive assembly includes a support base 11, an intermediate shaft 12, a lever frame 13, and a connecting frame 14. The support base 11 is located in the middle of the left side of the base 1. The intermediate shaft 12 is installed at the left end of the support base 11. Both ends of the intermediate shaft 12 are rotatably connected to the lever frame 13. The left end of the moving shaft 6 is rotatably connected to the connecting frame 14. The connecting frame 14 is slidably connected to the upper end of the lever frame 13. The lever frame 13 rotates around the intermediate shaft 12. The upper end of the lever frame 13 drives the intermediate shaft 12 to move to the right through the connecting frame 14. The intermediate shaft 12 drives the moving frame 7 to move to the left. The drive assembly also includes an electric push rod 15 and a connecting shaft 16. The electric push rod 15 is located at the lower end inside the base 1. The telescopic end of the electric push rod 15 is provided with the connecting shaft 16. The connecting shaft 16 is slidably connected to the lower end of the lever frame 13. The input end of the electric push rod 15 is electrically connected to the output end of the external controller. When the extension end of the electric push rod 15 retracts, it drives the connecting shaft 16 to move to the right. The connecting shaft 16 drives the lower end of the lever frame 13 to move to the right. The connecting shaft 16 slides relative to the long sliding hole at the lower end of the lever frame 13. The support base 11 is equipped with a force sensor 17. The left end of the force sensor 17 is fixedly connected to the intermediate shaft 12. The output end of the force sensor 17 is electrically connected to the input end of the external controller. The intermediate shaft 12 has a longitudinal movement space in the middle of the support base 11. During the process of the lever frame 13 being subjected to force, the lever frame 13 will squeeze the force sensor 17 through the intermediate shaft 12. Thus, the force sensor 17 can indirectly detect the tension pressure. When the set pressure is reached, the external controller controls the electric push rod 15 to stop working.

[0023] The working principle of the winding drum with tensioning function provided by this utility model is as follows: In use, the winding drum core is inserted into the outside of the three rubber pads 9, and then the external controller is adjusted. The telescopic end of the electric push rod 15 retracts, driving the connecting shaft 16 to move to the right. The connecting shaft 16 drives the lower end of the lever frame 13 to move to the right. The connecting shaft 16 slides relative to the long sliding hole at the lower end of the lever frame 13. The lever frame 13 rotates around the intermediate shaft 12. The upper end of the lever frame 13 drives the intermediate shaft 12 to move to the right through the connecting frame 14. The intermediate shaft 12 drives the moving frame 7 to slide to the left along the guide plate 18. The inclined sliding hole slides relative to the sliding shaft 8. The inclined sliding hole is inclined from right to left away from the axis of the moving shaft 6. The moving frame 7 slides relative to the sliding shaft 8 and pushes the sliding column 4 to move outward. The sliding column 4 drives the support plate 5 to open. The support plate 5 tensions the cylinder core through the rubber pad 9. The intermediate shaft 12 has a longitudinal movement space in the middle of the support seat 11. During the process of the lever frame 13 being subjected to force, the lever frame 13 will squeeze the pressure sensor 17 through the intermediate shaft 12. In this way, the pressure sensor 17 can indirectly detect the tensioning pressure. When the set pressure is reached, the external controller controls the electric push rod 15 to stop working.

[0024] It is worth noting that the electric actuator 15 and force sensor 17 disclosed in the above embodiments can be freely configured according to the actual application scenario. The electric actuator 15 can be an ANT-52 electric actuator, and the force sensor 17 can be an S-type force sensor of model K-25. The external controller controls the operation of the electric actuator 15 and the force sensor 17 using methods commonly used in the prior art.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
