[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1-5 , a pressing device for producing electromagnetic shielding films, comprising a device body 1 for pressing and producing electromagnetic shielding films, the device body 1 is the prior art (application number: 202120064087.4), a mounting frame 2 is fixed to the upper surface of the device body 1 corresponding to the manual adjustment screw, and connecting rods 3 are rotatably provided at both ends of the mounting frame 2, and a self-locking component is provided on the upper surface of the mounting frame 2 corresponding to the connecting rod 3, the lower end of the connecting rod 3 is fixedly connected to the upper end of the adjacent manual adjustment screw, a turntable 4 is installed in the middle of the rod body of the connecting rod 3, and the outer ring surface of the turntable 4 is provided with a matching pointer 5 corresponding to the scale lines, a pair of clamping plates 6 are commonly provided on the upper surface of the device body 1 corresponding to the lower ends of the two connecting rods 3, and a left-right threaded rod 7 is commonly installed in the middle of the clamping plate 6, and a matching first motor 8 is installed on the upper surface of the device body 1 corresponding to the left-right threaded rod 7.

[0025] Example 2

[0026] Reference Figure 1-5, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] The self-locking component includes a worm wheel 9 and a worm 10. The worm wheel 9 is installed at the end of the upper end of the connecting rod 3. The worm 10 is installed on the upper surface of the mounting frame 2 and meshes with the worm wheel 9. The setting of the worm wheel 9 and the worm 10 allows personnel to drive the connecting rod 3 to rotate through the worm 10, that is, the worm 10 drives the manual adjustment screw to rotate, thereby completing the operation of adjusting the pressing gap. In this process, the self-locking property between the worm 10 and the worm wheel 9 can further improve the anti-loosening effect of the manual adjustment screw, and effectively reduce the torque requirement when the manual adjustment screw is rotated, that is, save manpower and improve the accuracy of personnel when rotating the manual adjustment screw; two second motors 11 are provided on the rear side of the upper surface of the mounting frame 2, and the output end of the second motor 11 is connected to the adjacent worm 10. The setting of the second motor 11 further improves the accuracy of the manual adjustment screw when rotating, and further saves manpower and improves the production efficiency when the device is used.

[0028] A protective cover 12 is installed on the upper surface of the device body 1 corresponding to the mounting frame 2. The rear side of the protective cover 12 is hinged to the device body 1. The setting of the protective cover 12 can prevent foreign debris from accidentally entering the meshing between the left-handed threaded rod 7 and the clamping plate 6 and the meshing between the worm wheel 9 and the worm 10, that is, it is prevented from being disturbed by debris and affecting the rotation of the manual adjustment screw. The cover body of the protective cover 12 is a transparent cover body, and a plurality of heat dissipation holes are arranged on the rear side of the protective cover 12. The transparent protective cover 12 is convenient for people to The staff can observe the running status of its internal parts conveniently at any time; the proximal ends of both ends of the clamping plate 6 are slidably mounted with guide frames 13, and the two ends of the guide frames 13 are fixed to the upper surface of the device body 1. The setting of the guide frames 13 enables the clamping plate 6 to maintain stability when moving; the outer ring surface of the lower end of the connecting rod 3 is provided with an anti-slip ring 14, and the two ends of the clamping plate 6 are provided with matching arc-shaped fitting surfaces corresponding to the anti-slip ring 14. The setting of the anti-slip ring 14 enables the clamping plate 6 to be more stable and firm when clamping the connecting rod 3.

[0029] Principle and advantages of use: During the use of the utility model, the electromagnetic shielding film is produced and pressed through the device main body 1, and in this process, the pressing gap is adjusted through the manual adjustment screw in the device main body 1. In the above process, since the connecting rod 3 is fixedly connected to the manual adjustment screw, when the personnel adjusts the pressing gap of the electromagnetic shielding film, the personnel can drive the connecting rod 3 to rotate through the worm 10, that is, the worm 10 drives the manual adjustment screw to rotate, thereby completing the operation of adjusting the pressing gap. At the same time, the self-locking property between the worm 10 and the worm wheel 9 makes the manual adjustment screw unable to rotate by itself, and effectively reduces the torque requirement when the manual adjustment screw is rotated, that is, it saves manpower and improves the accuracy of the personnel when turning the manual adjustment screw.

[0030] At the same time, in the above process, through the setting of the first motor 8, when the personnel adjust the lamination gap of the electromagnetic shielding film, the two clamping plates 6 can be driven away from each other by the first motor 8 and the left and right threaded rods 7, that is, at this time, the connecting rod 3 can be driven by the worm gear 9, and when the lamination gap is adjusted, the two clamping plates 6 can be driven close to each other by the first motor 8 until the ends of the clamping plates 6 tightly clamp the two connecting rods 3. At this time, the connecting rod 3 cannot rotate freely under the action of the clamping plates 6, that is, it further avoids the phenomenon of accidental loosening and rotation of the manually adjusted screw during the operation of the device, thereby effectively ensuring the lamination thickness of the electromagnetic shielding film during the production process.

[0031] It should be further explained that the setting of the self-locking component not only improves the anti-loosening effect of the manual adjusting screw, but also effectively reduces the torque requirement when the manual adjusting screw is rotated, that is, it saves manpower and improves the accuracy of personnel turning the manual adjusting screw; the setting of the second motor 11 further improves the accuracy of the manual adjusting screw when it is rotated, and further saves manpower, and improves the production efficiency when the device is used; the setting of the protective cover 12 can prevent external debris from accidentally entering the meshing between the left and right threaded rod 7 and the clamping plate 6 and the meshing between the worm wheel 9 and the worm 10, that is, it avoids the phenomenon that the two are disturbed by debris and affect the rotation of the manual adjusting screw, and the transparent protective cover 12 makes it convenient for personnel to observe the operating status of its internal components at any time; the setting of the guide frame 13 allows the clamping plate 6 to maintain stability when moving; the setting of the anti-slip ring 14 allows the clamping plate 6 to be more stable and firm when clamping the connecting rod 3.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
