Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, and in particular relates to a cutting component for a winding machine. Background Art

[0002] In the packaging industry, a wrapping machine is a commonly used device for wrapping a film or other material around a workpiece to protect and fix the product. Existing wrapping machines usually include a cutting component, which is used to cut the material at the end of the wrapping process. However, the cutting component in the prior art has some shortcomings, such as the material may become loose when the workpiece is cut, which increases the difficulty for subsequent workers to bundle the workpiece.

[0003] For example, Chinese patent publication number CN217102326U discloses a cutting mechanism for producing stretch film, which improves the cutting process by increasing the degree of automation and precision, and another Chinese patent publication number CN211810365U discloses a winding device that can automatically cut off the film, which improves stability through a shock-absorbing component;

[0004] Both of the above patents can achieve certain benefits, but neither fully solves the problem of loose material after the workpiece is cut;

[0005] Therefore, it is necessary to propose a novel cutting component for a winding machine. Utility Model Content

[0010] A pressing component is also installed on the output end of the hydraulic cylinder, and the pressing component is used to press the winding workpiece.

[0011] The pressing assembly includes a connecting bar fixed on the output end of the hydraulic cylinder, a mounting frame is fixed to one end of the connecting bar away from the hydraulic cylinder, and a pressing arc plate is slidably connected to the inner side of the mounting frame;

[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0026] like Figure 1-4 As shown, a cutting assembly for a winding machine includes a device body 1, two support frames 2 are installed on the top of the device body 1, and a winding machine is installed between the two support frames 2. The winding machine can be the most commonly used winding machine in the current factory. The simplest one is a motor driving a winding rod to rotate. Because it is an existing mature technology, it will not be described here. The outer side of the winding machine is wound with a winding workpiece 3;

[0027] A support and installation frame 4 is also provided on the top of the device body 1. At least one hydraulic cylinder 6 is fixed on the top of the inner side of the support and installation frame 4. A cutting piece 7 is fixed vertically downward at the output end of the hydraulic cylinder 6. The cutting piece 7 is set in an inverted triangle as a whole. When it moves downward with the stroke rod of the hydraulic cylinder 6, the wound workpiece 3 can be cut. An electric heating wire is provided inside the cutting piece 7. Through this arrangement, the electric heating wire can be started when the cutting piece 7 moves downward, and then the wound workpiece 3 can be better cut through the setting of the electric heating wire.

[0028] When in use, the winding workpiece 3 can be wound by the winding machine. After the winding is completed, the hydraulic cylinder 6 can be driven to drive the cutting piece 7 to move downward through the stroke rod of the hydraulic cylinder 6, so that the cutting piece 7 cuts the winding workpiece 3, and one of the support frames 2 can be separated from the winding machine, so as to facilitate the removal of the wound workpiece 3.

[0029] A pressing component is also installed on the output end of the hydraulic cylinder 6 , and the pressing component is used to press the winding workpiece 3 .

[0030] See attached Figure 2-3The pressing component includes a connecting bar 8 fixed on the output end of the hydraulic cylinder 6. The connecting bar 8 can be made of metal material, such as iron steel, so that it can support the components thereon. A mounting frame 10 is fixed to the end of the connecting bar 8 away from the hydraulic cylinder 6, and a pressing arc plate 9 is slidably connected to the inner side of the mounting frame 10. By setting the pressing arc plate 9, the winding workpiece 3 on the winding machine can be pressed to avoid the loosening of the winding workpiece 3 when the cutting piece 7 cuts the winding workpiece 3. The overall length of the pressing arc plate 9 is greater than the overall length of the mounting frame 10, so that the area of ​​the pressing arc plate 9 that can be attached to the winding workpiece 3 is increased, and the curvature of the pressing arc plate 9 is consistent with the curvature of the winding workpiece 3 wound on the winding machine, so that when the pressing arc plate 9 is winding the winding workpiece 3, a gap is avoided between the pressing arc plate 9 and the winding workpiece 3 due to inconsistent curvature;

[0031] A driving assembly is also installed on the inner side of the mounting frame 10 , and the driving assembly is used to drive the pressing arc plate 9 to slide on the inner side of the mounting frame 10 .

[0032] See attached Figure 4 The driving assembly includes a meshing wheel 12 rotatably connected to the inner side of the mounting frame 10, and a meshing tooth 11 meshing with the meshing wheel 12 is provided on the side of the pressing arc plate 9 close to the meshing wheel 12. When the meshing tooth 11 meshes with the meshing wheel 12, the pressing arc plate 9 can move forward and backward in the mounting frame 10. A driving motor 5 is also installed on the inner side of the mounting frame 10, and the output end of the driving motor 5 is fixedly connected to the center position of the meshing wheel 12;

[0033] When the arc plate 9 is pressed to press the winding workpiece 3, the driving motor 5 can be started according to the winding direction of the winding workpiece 3, so that the output end of the driving motor 5 drives the meshing wheel 12 to rotate, and through the meshing connection between the meshing wheel 12 and the meshing tooth 11, the meshing wheel 12 can drive the meshing tooth 11 and the pressing arc plate 9 to slide up and down, and the winding workpiece 3 cut off by the cutting piece 7 in the front section is flattened on the winding machine, thereby further ensuring the winding effect of the winding workpiece 3 until the staff bundles the winding workpiece 3.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
