[0061] The following will describe some embodiments of the present invention in detail with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0062] In the prior art, when sewing pockets on clothing, a laser device is used to make a special opening in the shape of ">一<", which has technical problems such as high purchase cost of the laser device, complex operation process, poor use environment, and high maintenance cost.

[0063] In view of this, the present invention provides a clothing pocket-opening knife, which includes: a straight knife 100 and two V-shaped knives 200 located on both sides of the straight knife 100, and each of the two V-shaped knives 200 and the straight knife 100 forms a Y-shaped blade.

[0064] Two V-shaped knives 200 are located on both sides of the straight knife 100. Each of the two V-shaped knives 200 and the straight knife 100 forms a Y-shaped blade edge, and they are combined to form a ">一<" shaped blade edge. First, both the V-shaped knives 200 and the straight knife 100 are ordinary knives and the equipment structure is simple, so the purchase cost is low. Moreover, before use, only the model of the V-shaped knife 200 and / or the distance between the two V-shaped knives 200 needs to be adjusted to realize the processing of ">一<" shaped openings of different sizes. The operation is simple. During use, the cutting is carried out by the cutting edge of the knife, which belongs to a physical action and no polluting gas is generated. After use, due to the simple equipment structure, the maintenance cost is low.

[0065] In an alternative solution of this embodiment, a slope 140 is provided below the straight knife 100. The lower edge of the slope 140 is the cutting edge. The side surface of the lower edge in the thickness direction of the straight knife 100 is a plane, and the two side surfaces in the length direction are planes. In this way, when the two straight knives 100 are overlapped back to back, the cutting edges of the two straight knives 100 can be mutually adhered, and moreover, the side surfaces of the two straight knives 100 in the length direction can be adhered to the V-shaped knives 200 located on the sides.

[0066] In an alternative solution of this embodiment, please refer to Figure 2 , the clothing bag-opening knife is provided with two straight knives 100. One of the straight knives 100 is the left straight knife 110, and the other straight knife 100 is the right straight knife 120. The left straight knife 110 and the right straight knife 120 at least partially overlap and can move relatively in the horizontal direction.

[0067] Regarding the structure of the V-shaped knife 200, specifically:

[0068] In an alternative solution of this embodiment, please refer to Figure 3 , both the left V-shaped knife 210 and the right V-shaped knife 230 include a knife handle 240 and a knife body 250. The width of the knife handle 240 is smaller than the width of the knife body 250. The end of the knife body 250 is provided with a V-shaped blade edge. The main body part of the knife body 250 is set as a rectangular structure. Four slopes are provided at the lower part of the rectangular structure. The V-shaped knife 200 has two intersecting blade edges, and the blade edge is the intersection line of two intersecting slopes. Further, the end surface of the V-shaped knife 200 that is adhered to the straight knife 100 is smooth. Since the two end surfaces of the straight knife 100 are also smooth, when the end surfaces of the V-shaped knife 200 and the straight knife 100 are adhered, there is no gap between the two knives, and a Y-shaped blade edge is formed in combination.

[0069] In an alternative solution of this embodiment, please refer to Figure 1, the clothing bag-opening knife includes a left support 310 and a right support 320, and the left support 310 and the right support 320 can move relative to each other in the horizontal direction. Taking one of the V-shaped knives 200 as the left V-shaped knife 210 and the other V-shaped knife 200 as the right V-shaped knife 230, the left V-shaped knife 210 is connected below the left support 310, and the right V-shaped knife 230 is connected below the right support 320. When the left support 310 and the right support 320 approach each other in the horizontal direction, the left V-shaped knife 210 and the right V-shaped knife 230 approach each other. When the left support 310 and the right support 320 move away from each other in the horizontal direction, the left V-shaped knife 210 and the right V-shaped knife 230 move away from each other.

[0070] In an alternative solution of this embodiment, the clothing bag-opening knife further includes a left clamping part 610 and a right clamping part 620. One end of the left clamping part 610 is connected to the left support 310, and the other end is connected to the left single-edge knife 110. Similarly, one end of the right clamping part 620 is connected to the right support 320, and the other end is connected to the right single-edge knife 120. The connection between the left single-edge knife 110 and the left support 310 is achieved through the left clamping part 610, and the connection between the right single-edge knife 120 and the right support 320 is achieved through the right clamping part 620.

[0071] Taking the left single-edge knife 110 as an example, please refer to Figure 1 , both sides of the left clamping part 610 are fixedly connected to the left single-edge knife 110 and the left support 310 respectively. When the left support 310 moves in the horizontal direction, it can带动 the left single-edge knife 110 to move in the horizontal direction. And a left V-shaped knife 210 is arranged below the left support 310. Therefore, the corner of the left V-shaped knife 210 keeps abutting against the end of the left single-edge knife 110, and they are combined to form a "> -" shaped cutting edge.

[0072] Similarly, the right single-edge knife 120 is connected to the right support 320 through the right clamping part 620, and the corner of the right V-shaped knife 230 keeps abutting against the end of the right single-edge knife 120, and they are combined to form a "- <" shaped cutting edge. Because the two single-edge knives 100 partially overlap and can move horizontally under the drive of the left support 310 and the right support 320, the size of the overlapping part of the two single-edge knives 100 will change with the horizontal movement of the single-edge knives 100. That is, the length of the straight part of the combined "> - <" shaped cutting edge changes with the horizontal movement of the single-edge knives 100, realizing the adjustment of the length of the straight part.

[0073] The following details the structure and positional relationship of the left clamping part 610 and the right clamping part 620:

[0074] In an alternative solution of this embodiment, please refer to Figure 7 , the left clamping part 610 and the right clamping part 620 are arranged in central symmetry, that is, after rotating the left clamping part 610 by 180°, its assembly form is the same as that of the right clamping part 620.

[0075] In an alternative embodiment of this embodiment, both the left clamping portion 610 and the right clamping portion 620 include a first section 611, a second section 612, and a third section 613, which are sequentially connected and perpendicular to each other. Taking the left clamping portion 610 as an example, the surface of the first section 611 is detachably connected to the surface of the left support 310; the inner surface of the third section 613, adjacent to the second section 612, is in contact with the end of the left straight blade 110 facing away from the left V-shaped blade 210; and the ends of the second section 612 are connected to the first section 611 and the third section 613, respectively.

[0076] Furthermore, the first section 611 is detachably connected to the left support 310 by bolt connection. Of course, other connection methods, such as snap-fit ​​connection, should also be within the scope of protection of the present invention.

[0077] In an optional solution of this embodiment, the garment bag cutter further includes an adjustment screw 710. The adjustment screw 710 has a first threaded area corresponding to the left support 310 and a second threaded area corresponding to the right support 320, with the first threaded area and the second threaded area having opposite rotation directions. The left support 310 is provided with a left-threaded hole 311, and the right support 320 is provided with a right-threaded hole 321. The left and right threaded holes 311 and 321 have opposite rotation directions. After the adjustment screw 710 passes horizontally through the left and right supports 310 and 320, the threads on the adjustment screw 710 match the threads on the left and right supports 310 and 320. Rotating the adjustment screw 710 can cause the left and right supports 310 and 320 to move toward or away from each other in the horizontal direction. Of course, other control mechanisms, such as gear matching, are also within the scope of protection of the present invention.

[0078] In an alternative embodiment of this embodiment, the garment bag cutter further includes a knife holder 800, with the left support 310 and the right support 320 movably connected below the knife holder 800. In an alternative embodiment of this embodiment, the knife holder 800 includes a knife holder body 820 and a gusset plate 830. The knife holder body 820 and the gusset plate 830, when engaged, form a slot 840. A protruding structure 312 corresponding to the slot 840 is provided above the left support 310 and the right support 320. The left support 310 and the right support 320 are connected to the knife holder 800 by inserting the protruding structure 312 into the slot 840. Furthermore, the slot 840 extends along the length of the knife holder 800, allowing the protruding structure 312 to move horizontally along the length of the knife holder 800. Of course, other connection methods, such as pulley and track connections, are also within the scope of protection of the present invention.

[0079] In an optional solution of this embodiment, a main support 810 is further provided below the knife seat 800. Figure 8A groove 811 is also provided under the main support 810. The end of the left straight knife 110 facing away from the left V-shaped knife 210 is at least partially inserted into the groove 811. Similarly, the end of the right straight knife 120 facing away from the right V-shaped knife 230 is also at least partially inserted into the groove 811. The left straight knife 110 and the right straight knife 120 can move horizontally in the groove 811.

[0080] In an alternative embodiment of the present invention, leveling screws 720 are provided on the bottom wall of the groove 811 and below the left support 310 and the right support 320. The left and right slotted blades 110 and 120 are fitted with the leveling screws 720. Preferably, two leveling screws 720 are provided on each component.

[0081] In this embodiment, the V-knife can be replaced manually or automatically, as described below:

[0082] Method 1: Manually change the V-knife:

[0083] In an optional solution of this embodiment, the garment bag opening knife includes a left pressing plate 410 and a right pressing plate 420, and a notch is provided at the lower portion of the left support 310 and the right support 320. The left pressing plate 410 is provided in the lower notch of the left support 310, and a left clamping gap 510 for clamping the left V-shaped knife 210 is formed between the left pressing plate 410 and the left support 310. The right pressing plate 420 is provided in the lower notch of the right support 320, and a right clamping gap 520 for clamping the right V-shaped knife 230 is formed between the right pressing plate 420 and the right support 320. For details about the left clamping gap 510 and the right clamping gap 520, please refer to Figure 4 and Figure 5 .

[0084] In an optional solution of this embodiment, the handle 240 of the left V-shaped blade 210 is engaged with the left engaging gap 510, and the handle 240 of the right V-shaped blade 230 is engaged with the right engaging gap 520. In actual use, openings at different angles can be achieved by manually replacing the left V-shaped blade 210 and the right V-shaped blade 230.

[0085] In this embodiment, a structure of a left pressure plate 410 and a right pressure plate 420 is provided. Specifically:

[0086] See Figure 6 The left pressure plate 410 and the right pressure plate 420 both include a vertical plate 411 and a horizontal plate 412 that are vertically connected. Stepped installation notches are provided below the left support 310 and the right support 320. The vertical plate 411 of the left pressure plate 410 is vertically attached to the left support 310, and the vertical plate 411 of the right pressure plate 420 is vertically attached to the right support 320.

[0087] The horizontal plate 412 of the left pressure plate 410 is configured to be L-shaped, and the bottom wall of the horizontal plate 412 of the left pressure plate 410 is located in the same plane as the bottom wall of the left support 310; the horizontal plate 412 of the right pressure plate 420 is configured to be L-shaped, and the bottom wall of the horizontal plate 412 of the right pressure plate 420 is located in the same plane as the bottom wall of the right support 320. Because the horizontal plate 412 is configured to be L-shaped, a long strip of gap can be formed between it and the left support 310 or the right support 320. This gap is the left clamping gap 510 or the right clamping gap 520 that can be used to clamp the V-shaped knife 200. The bottom wall of the above-mentioned horizontal plate 412 is located in the same plane as the bottom wall of the left support 310 or the right support 320, so that the formed plane can be tightly fitted with the V-shaped knife 200.

[0088] Furthermore, a through hole is provided on the vertical plate 411, and a threaded blind hole is correspondingly provided on the vertical surface of the stepped installation notch of the left support 310 or the right support 320. The fasteners pass through the through holes on the vertical plate 411 and the threaded blind holes on the left support 310. By controlling the tightening degree of the fasteners, the width of the left clamping gap 510 or the right clamping gap 520 can be fine-tuned.

[0089] In addition, it should be noted that leveling screws 720 are provided on the bottom walls of the horizontal plate 412 and the left and right supports 310 and 320. The leveling screws 720 are used to adjust the horizontal flatness of the V-shaped blade 200. Taking the left V-shaped blade 210 as an example, the leveling screws 720 need to be provided on the bottom wall of the horizontal plate 412 of the left pressure plate 410 and the bottom wall of the left support 310. Preferably, two leveling screws 720 are provided on each component. The handle 240 of the left V-shaped blade 210 is inserted into the left clamping gap 510. Because the width of the blade 250 is greater than the handle 240, the upper surface of the blade 250 is in contact with the leveling screws 720. The horizontal flatness of the blade of the left V-shaped blade 210 is adjusted by controlling the extension of the leveling screws 720.

[0090] Method 2: Automatic V-knife change:

[0091] For the optional solutions of this embodiment, see Figure 10 The garment bag opening knife includes a knife feed mechanism 900, which includes a movable bracket 910 and a rotating knife holder 920. The movable bracket 910 is connected to the bottom of the left support 310 or the right support 320 and moves laterally relative to the left support 310 or the right support 320. The rotating knife holder 920 is disposed below the movable bracket 910. A plurality of V-shaped knives 200 are disposed below the rotating knife holder 920. The rotating knife holder 920 can rotate about the central axis of the rotating knife holder 920 and drive the plurality of V-shaped knives 200 to rotate.

[0092] The structure of the mobile bracket 910 is described in detail below:

[0093] For the optional solutions of this embodiment, see Figure 11 and Figure 12 The movable bracket 910 includes a motor fixing plate 911, a transmission plate 912, a turning plate 913 and a disc plate 914. The motor fixing plate 911 is vertically arranged and connected to the motor. The transmission plate 912 is perpendicular to the motor fixing plate 911. A transmission shaft is provided on the transmission plate 912.
