[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the utility model is a cutting device for shaping trouser ears, comprising a base 1, a workbench 2 is embedded in the upper side wall of the base 1, and hydraulic rods 3 are installed at the four corners of the upper side wall of the base 1, the base 1 is connected to the top frame 4 through the hydraulic rods 3, a driving component 6 is embedded on the outer wall of one side of the top frame 4, and a hoisting component 7 is provided at the shaft end of the driving component 6, and a cutter component 8 is provided below the hoisting component 7;

[0033] The driving assembly 6 is composed of a servo motor 601 and a screw rod 602 on its motor shaft, and a driving sleeve 603 is also installed on the screw rod 602, and the driving sleeve 603 is connected to the cross frame 701 in the hanging assembly 7 at the same time, and the middle part of the cross frame 701 is fixedly connected with a hanging sleeve 702, and the bottom side wall of the hanging sleeve 702 is connected to the electric rod 704 through the fixed frame 703, and the shaft end of the electric rod 704 is connected to the knife holder 801 on the cutting knife assembly 8 through the rod sleeve 705, and a cross-cutting knife 802 is installed on the horizontal central axis of the knife holder 801, and the next high end of the knife holder 801 is sleeved with a fixed sleeve 803, and the bottom side wall of the fixed sleeve 803 is connected to the vertical cutting knife 805 through a spring rod 804;

[0034] A top groove 101 is provided on the upper side wall of the base 1, and external connecting columns 102 are welded at the four corners of the upper side wall of the base 1. The base 1 is clamped with the workbench 2 through the top groove 101, and the base 1 is clamped with the bottom of the hydraulic rod 3 through the external connecting column 102; a plurality of transverse grooves 201 are provided on the upper side wall of the workbench 2, and vertical grooves 202 are provided at both ends of the transverse grooves 201, the transverse grooves 201 and the vertical grooves 202 are interconnected, and the cross-sections of the transverse grooves 201 and the vertical grooves 202 are both in a "V" shape, and plastic pads are bonded to the inner walls of the transverse grooves 201 and the vertical grooves 202 for protecting the cutter; the top frame 4 is arranged in a square frame structure, and slide grooves 401 are provided on the central axis on both sides of the top frame 4, and the top frame 4 is slidably connected with the drive sleeve 603 in the drive assembly 6 through the slide grooves 401 to prevent the drive sleeve 603 from escaping from the slide grooves 401;

[0035] The screw rod 602 in the driving assembly 6 is arranged at the center of the slide slot 401, and the servo motor 601 on the other end of the screw rod 602 is embedded on the side outside of the top frame 4, and the servo motor 601 is connected to the top frame 4 through the motor frame; there are two groups of driving assemblies 6, and the two groups of driving assemblies 6 are arranged on both sides of the hanging assembly 7, and the telescopic shaft end of the electric rod 704 in the hanging assembly 7 is arranged vertically downward to ensure that the electric rod 704 can be extended or retracted downward;

[0036] The cross-cutting knife 802 and the knife holder 801 in the cutting knife assembly 8 are arranged parallel to each other, and the vertical cutting knife 805 and the knife holder 801 are arranged perpendicular to each other. The upper side walls of both ends of the vertical cutting knife 805 are connected to the knife holder 801 through spring rods 804 respectively. The arrangement of the spring rods 804 ensures that when the vertical cutting knife 805 contacts the cloth strip, it does not cut immediately but abuts against it, thereby temporarily stabilizing the cloth strip.

[0037] When the above arrangement is used, when the cloth strip is completely and evenly laid on the workbench 2, the cutting work of the trouser ears can be started. First, the servo motor 601 in the driving assembly 6 works, and the horizontal position of the hoisting assembly 7 is adjusted through the screw rod 602 and the driving sleeve 603, and then the electric rod 704 is extended to drive the cutter assembly 8 to move downward. When the cutter assembly 8 moves downward, the cross-cutting knife 802 moves downward accordingly and gradually approaches and is directly connected to the cross-cutting groove 201. When the cross-cutting work of the cloth strip is completed, while it is cutting horizontally, the vertical cutting knife 805 also contacts the cloth strip at the same time. However, because the spring rod 804 is provided on it, the vertical cutting knife 805 does not cut the cloth strip immediately when it contacts the cloth strip. It will continue to abut with the downward movement of the knife holder 801 until the spring rod 804 is completely compressed, that is, when the cross-cutting knife 802 completes cutting, the vertical cutting knife 805 starts cutting. That is, the overall working state is that the front and rear feet complete the cutting work with a time difference.

[0038] Among them Figure 4 As shown, a clamping assembly 5 is detachably fixedly installed in the upper side wall of the base 1 on the inner side of the hydraulic rod 3, and the clamping assembly 5 is composed of a right-angle plate 501 and a slide bar 502 inserted thereon, wherein a spring ring 503 is sleeved on a section of the outer wall of the slide bar 502 located below the right-angle plate 501, and a clamping plate 504 is provided on the bottom side wall of the slide bar 502;

[0039] The right-angle plate 501 in the clamping assembly 5 is arranged in an "L" shape, and the bend of the right-angle plate 501 is arranged toward one side of the workbench 2, and the bottom side wall of the vertical end of the right-angle plate 501 is connected to the inner connecting column 103; a sliding rod 502 is inserted in the horizontal section of the right-angle plate 501, and the length of the clamping plate 504 in the clamping assembly 5 is the same as the length of the workbench 2. The sliding rods 502 in the two clamping assemblies 5 are arranged corresponding to one clamping plate 504, and the two ends of the spring ring 503 in the clamping assembly 5 are respectively abutted against the bottom side wall of the horizontal section of the right-angle plate 501 and the upper side wall of the clamping plate 504, which is used for the installation of the clamping assembly 5;

[0040] When using the above arrangement, first place the cloth strip that needs to be switched into trouser ears on the workbench 2 and lay it out, then pull the slide bar 502 in the clamping assembly 5 to compress the spring coil 503, and then the clamping plate 504 moves up to reveal the gap between it and the workbench 2, and then insert the cloth strip under the clamping plate 504, and then release the slide bar 502, and then the spring coil 503 returns to its initial state, and then under the elastic force of the spring coil 503, the slide bar 502 moves down with the clamping plate 504 until it abuts against the outer wall of the cloth strip. Because they are connected when in contact with each other, when it is necessary to flatten the cloth strip on the workbench 2 for a second time, it is only necessary to pull the end of the cloth strip located outside the clamping plate 504.

[0041] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
