Technical Field

[0001] This utility model relates to the field of Mylar sheet cutting technology, specifically a positioning device for Mylar sheet cutting. Background Technology

[0002] Mylar film refers to a high-pressure unidirectional stretched film made of polymer materials, also known as stretch film. Mylar film comes in a variety of colors such as milky white, black, natural color, and transparent. It is used in motors, capacitors, coils and other fields, and is therefore a very common material in electronic components.

[0003] Mylar sheets need to be cut during the production and processing. Existing cutting devices can only position mylar sheets of a single specification, which has a limited scope of application and is inconvenient to adjust according to the specifications of the mylar sheets. Therefore, we propose a positioning device for cutting mylar sheets to solve the above problems. Utility Model Content

The rotating shaft 11 is provided with guide openings 111, and positioning components 12 are slidably installed in the guide openings 111.

[0024] Example 2

[0025] Reference Figure 1-3This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, at least two rotating shafts 11 are provided and arranged in parallel to each other. One end of the two rotating shafts 11 is connected by a belt drive structure. That is, the ends of the two rotating shafts 11 are respectively fixedly sleeved with pulleys, and the two pulleys are connected to a drive belt. One end of one rotating shaft 11 is connected to a drive motor 13 by a belt drive structure. That is, the end of one rotating shaft 11 is fixedly sleeved with two pulleys. One pulley is connected to the drive belt of the other rotating shaft 11, and the other pulley is connected to the pulley fixed to the output shaft of the drive motor 13. The drive motor 13 is fixedly mounted on the top of the mounting base 14, and one end of the mounting base 14 is fixedly connected to the worktable 1.

[0026] Specifically, the guide opening 111 has a cross-shaped structure, which prevents the slider 121 from falling off while it moves within the guide opening 111.

[0027] Specifically, the positioning component 12 includes a slider 121, a connecting strip 122, a side guard strip 123, a support ring 124, an anti-slip sleeve 125, and a positioning bolt 126. The slider 121 is provided in multiple sets, and each set includes two sliders 121. Each set of sliders 121 is slidably disposed in a guide opening 111. The support ring 124 is fixedly sleeved on one side of each slider 121, and the anti-slip sleeve 125 is fixedly sleeved on the outside of the support ring 124. The positioning bolt 126 is connected to one end of the other side of the slider 121 through a threaded structure. The positioning bolt 126 abuts against the outer wall of the rotating shaft 11. One end of the connecting strip 122 is fixedly connected to the other end of the other side of the slider 121, and the other end of the connecting strip 122 is fixedly connected to the side guard strip 123. Each set of sliders 121 is symmetrically disposed on a rotating shaft 11.

[0028] Specifically, a cutting blade 71 is fixedly mounted on the output shaft of the cutting motor 7. The bottom of the cutting blade 71 is provided with a cutting groove 101, which is recessed in the top surface of the worktable 1.

[0029] Specifically, the clamping assembly 8 includes an L-shaped rod 81, a movable groove 82, a spring 83, and a movable rod 84. One end of the L-shaped rod 81 is fixedly connected to the support base 6, and the other end of the L-shaped rod 81 is recessed with a movable groove 82. One end of the movable groove 82 is fixedly connected to one end of the spring 83, and the other end of the spring 83 is fixedly connected to one end of the movable rod 84. The movable rod 84 is slidably sleeved in the movable groove 82, and the other end of the movable rod 84 is fixedly connected to the clamping frame 9.

[0030] Specifically, the clamping frame 9 is a rectangular box structure, and clamping rollers 91 are rotatably installed on both sides inside the clamping frame 9. The length direction of the clamping rollers 91 is perpendicular to the length direction of the linear motor 3, so that the Mylar film will not be lifted when the clamping rollers 91 move.

[0031] The working principle and process are as follows: Based on the required Mylar sheet size, first manually adjust the positioning component 12 and manually loosen the positioning bolt 126, disengaging the nut of the positioning bolt 126 from the outer wall of the rotating shaft 11. At this point, a single slider 121 can be moved. The slider 121 drives the anti-slip sleeve 125 to move synchronously. The anti-slip sleeve 125 is made of elastic rubber, and its outer wall slides in contact with the worktable 1. Simultaneously, the edge strip 123 moves synchronously with the slider 121, thereby changing the distance between the two edge strips 123 to accommodate different Mylar sheet sizes. The edge strip 123 blocks and limits the ends of the Mylar sheet, ensuring the cut Mylar sheet is positioned between the two edge strips 123. Simultaneously, the anti-slip sleeve 125, in conjunction with the top surface of the worktable 1, presses and positions the Mylar sheet for cutting. When the drive motor 13 is powered on, it drives the two rotating shafts 11 to rotate synchronously. The rotating shafts 11 then drive the anti-slip sleeve 125 to rotate synchronously. The anti-slip sleeve 125 drives the Mylar sheet to move towards the cutting motor 7 through friction. After reaching the cutting position, the drive motor 13 stops, the cylinder 5 works, and the cutting motor 7 descends. When the cutting blade 71 extends into the cutting groove 101, it stops, and the cutting motor 7 is powered on. At the same time, it works in conjunction with the linear motor 3 to cut the Mylar sheet. During cutting, the pressure roller 91, under the elastic force of the spring 83, works in conjunction with the top surface of the worktable 1 to always press the Mylar sheet. At the same time, the length direction of the pressure roller 91 is perpendicular to the length direction of the linear motor 3, so that the Mylar sheet will not be lifted when the pressure roller 91 moves.

[0032] It should be noted that the specific models and specifications of the linear motor, cutting motor, cylinder, and drive motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be described in detail here.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
