[0002] The wave tool seat on the capacitor film cutting machine is a key component for installing and fixing the wave-shaped cutting tool, and its main function is to cut the capacitor film and other flexible materials in a wave shape through the wave-shaped blade to meet specific processing requirements.

[0003] The existing wave tool seat includes an upper tool seat and a lower tool seat, and the upper tool seat and the lower tool seat fix the blade between the upper tool seat and the lower tool seat through clamping grooves or clamping slots. However, the clamping groove or clamping slot fixing method cannot make the blade completely adhere to the wave surface of the upper tool seat or the lower tool seat in actual use, resulting in a gap between the blade and the wave surface. When rotating at high speed or under cutting force, the blade is prone to vibration or deviation, which may reduce cutting accuracy (such as size deviation and surface roughness), accelerate blade wear, and even cause the blade to break or fly out, leading to safety accidents. Therefore, the present application provides an improved wave tool seat to meet the needs. SUMMARY

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Embodiment: refer to Figures 1-2 The improved wave knife seat shown in the figure, including with wave end face upper knife seat 1 and lower knife seat 2, upper knife seat 1 is provided with multiple groups of through holes 5, and each group of through holes 5 is located on the wave peak of the wave end face of upper knife seat 1;

[0025] The lower knife seat 2 is provided with multiple groups of threaded through holes 4 corresponding to the multiple groups of through holes 5, and each group of threaded through holes 4 is located on the wave trough of the wave end face of the lower knife seat 2.

[0026] The upper knife seat 1 and the lower knife seat 2 are clamped and fixed by the screw 3, and the blade is provided with a through hole matched with the screw 3.

[0027] The threaded through hole 4 is arranged on the wave trough of the wave end face of the lower knife seat 2, and the through hole 5 is located on the wave peak of the wave end face of the upper knife seat 1, and then a plurality of screws 3 are fixed, so that the blade is stably clamped and fixed between the upper knife seat 1 and the lower knife seat 2, and the surface of the blade is tightly attached to the wave end face of the upper knife seat 1 and the lower knife seat 2.

[0028] As a preferred embodiment in the embodiment, a cooperative fastening structure is also provided, which can simultaneously drive multiple screws 3 to rotate to realize clamping and fixing of the blade.

[0029] The purpose is to rotate multiple screws 3 simultaneously to fix the blade, improve the installation efficiency, and also make the forces of each part of the blade uniform (make the fastening forces of each screw 3 consistent), which is beneficial to the stable operation of the blade.

[0030] As a preferred embodiment in the embodiment, as Figure 3As shown, the cooperative fastening structure includes a toothed ring 7 and a drive gear 8 rotatably mounted on the upper end of the upper tool holder 1, and a transmission gear 6 fixed on the upper end of the corresponding screw 3.

[0031] The drive gear 8 and multiple sets of transmission gears 6 are all meshed with the gear ring 7.

[0032] The upper end of the drive gear 8 is provided with a groove that fits the end of a screwdriver (not limited to this). The drive gear 8 can be driven to rotate by the screwdriver, and then the gear ring 7 can drive multiple sets of transmission gears 6 to rotate, so as to achieve the simultaneous rotation of multiple sets of screws 3.

[0033] As a preferred embodiment of this invention, a limiting unit is also provided to limit the self-rotation of the drive gear 8.

[0034] To prevent the blade from rotating during operation and causing the drive gear 8 to loosen, thus avoiding safety accidents.

[0035] As a preferred embodiment of this example, Figure 4 As shown, the limiting unit includes a movable block 9 with a receiving cavity 10 at its lower end. The movable block 9 is vertically slidably disposed in the hollow cavity of the drive gear 8 via a slider 14. A limiting post 12 is fixed below the movable block 9, and the upper end of the limiting post 12 is located inside the receiving cavity 10. A top plate is fixed to the upper end of the limiting post 12, and the top plate is slidably penetrated by a through post 11 provided on the inner wall of the receiving cavity 10. The lower end of the movable block 9 is connected to the upper tool holder 1 via a connecting spring 13.

[0036] The upper end of the movable block 9 is provided with a groove that fits the end of a screwdriver (not limited to this), which can drive the drive gear 8 to rotate.

[0037] Initially, because the through column 11 slides through the top plate, the movable block 9 cannot rotate relative to the limiting column 12. At the same time, due to the action of the slider 14, the movable block 9 cannot rotate, which ultimately prevents the drive gear 8 from rotating and limits the drive gear 8.

[0038] When it is necessary to rotate the drive gear 8, the end of the screwdriver can be inserted into its upper groove, and the movable block 9 can be pressed to make the through post 11 move down and eventually move to the bottom of the top plate (at this time, the limitation unit on the drive gear 8 is released, making the operation convenient and quick). At this time, the movable block 9 can be rotated, and the drive gear 8 will be rotated through the movable block 9, which will eventually make the multiple sets of screws 3 rotate. After the screws 3 have completely fixed the blade, the screwdriver will separate from the groove. Under the action of the elastic force of the connecting spring 13, the movable block 9 will be driven to move upward, and finally the through post 11 will slide through the top plate again. At this time, the drive gear 8 is limited and cannot rotate.

[0039] It should be noted that the upper end of the connecting spring 13 is in sliding contact with the lower end of the movable block 9, and the lower end of the connecting spring 13 is fixedly connected with the upper end of the upper knife holder 1.

[0040] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
