[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example like Figure 1-Figure 5 As shown, the shearing device provided in the embodiment of the present invention comprises: A first shell 1, a connecting assembly 2 and a cutter assembly 3 are connected in sequence, the first shell 1 has an accommodating space 4 inside, a feeding channel 9 is formed between the first shell 1 and the connecting assembly 2, the accommodating space 4 is communicated with the feeding channel 9, the connecting assembly 2 has a cutter channel inside, the extension direction of the cutter channel intersects and is communicated with the extension direction of the feeding channel 9, the connecting assembly 2 is used to be connected to the frame body of the wire placement head, and the feeding channel 9 is used for the wire bundle body to be cut to pass through; An abutment block 5, wherein the abutment block 5 has a first end and a second end opposite to each other, and the first end is rotatably connected to the accommodating space 4; an elastic portion 6, one end of which is connected to the accommodating space 4, and the other end of which is connected to the second end of the abutting block 5, and the elastic portion 6 is used to provide a rebound force for the abutting block 5; Among them, the cutter assembly 3 can pass through the cutter channel and the feed channel 9 in sequence, and push the wire bundle body to be cut against the abutment block 5 in the accommodating space 4, and the second end of the abutment block 5 compresses the elastic part 6 to cut the wire bundle body to be cut.

[0025] Specifically, the accommodating space 4 is communicated with the feed channel 9, and the accommodating space 4 is used to accommodate the abutment block 5 and the elastic part 6. The side of the accommodating space 4 opposite to the feed channel 9 is communicated with the feed channel 9. A feed channel 9 is formed between the first shell 1 and the connecting component 2, and the feed channel 9 is used for the passage of the wire bundle body. A cutter channel is formed inside the connecting component 2, and the cutter channel is used for the passage of the cutter component 3, so that the cutter component 3 can push the wire bundle body to be cut in the feed channel 9 against the abutment block 5 through the cutter channel, so as to achieve the effect of cutting the wire bundle body to be cut.

[0026] When the cutter assembly 3 presses the body of the to-be-cut wire bundle against the abutment block 5, the abutment block 5 is subjected to pressure and compresses the elastic portion 6, so that the second end of the abutment block 5 rotates in a direction away from the cutter assembly 3, thereby effectively avoiding hard contact between the cutter assembly 3 and the abutment block 5, avoiding damage to the tool and extending the service life of the tool.

[0027] After the cutter assembly 3 completes the cutting action, the cutter assembly 3 releases the abutment effect with the abutment block 5, and the elastic part 6 pushes the abutment block 5 to reset under the action of elastic potential energy, so that the cutter assembly 3 cooperates with the abutment block 5 to perform the next cutting process on the tow body to be cut.

[0028] It should be noted that the feed channel 9 and the cutter channel can be perpendicular to each other or have a certain angle, which can be an acute angle or an obtuse angle. As long as the feed channel 9 intersects with the cutter channel, since the feed channel 9 intersects and is connected with the cutter channel, the cutter assembly 3 can push the wire bundle body to be cut in the feed channel 9 against the abutment block 5 through the cutter channel to achieve the effect of cutting the wire bundle body to be cut.

[0029] The elastic part 6 includes a spring, one end of which is connected to a side of the accommodating space 4 away from the feeding channel 9 , and the other end of the spring is connected to the second end of the abutment block 5 . The spring is used to provide a rebound force for the abutment block 5 .

[0030] like Figure 1-Figure 3 As shown, in a specific implementation, the cutter assembly 3 includes: A cutting knife 31 and a cylinder 32 connected in sequence, wherein the cutting knife 31 is located inside the cutting knife channel, and the cylinder 32 is connected to the connecting assembly 2; The cutting end of the cutting knife 31 facing away from the cylinder 32 pushes the to-be-cut wire bundle body against the abutment block 5 in the accommodating space 4 .

[0031] Specifically, the present application provides an embodiment of a cutting tool assembly 3, that is, the cutting tool assembly 3 includes a cutting knife 31 and a cylinder 32 connected in sequence. The telescopic end of the cylinder 32 is connected to the cutting knife 31. The cutting end of the cutting knife 31 facing away from the cylinder 32 abuts the to-be-cut tow body against the abutting block 5 in the accommodating space 4. The cylinder 32 is connected to the connecting assembly 2 so that the cutting knife 31 is located in the cutting knife channel and on the side of the cutting knife channel away from the accommodating space 4. The cylinder 32 can drive the cutting knife 31 to perform stretching or contracting movements, so that the cutting knife 31 reciprocates within the cutting knife channel.

[0032] It should be noted that there is a certain gap between the telescopic end of the cylinder 32 and the inside of the cylinder 32. This structural design can avoid the problem of excessive operating resistance of the cutting knife 31 when there is a small deviation in the axial direction between the cutting knife channel and the telescopic end of the cylinder 32.

[0033] As Figure 3 shown, in a specific implementation, the cutting end is in the shape of an inclined mouth.

[0034] Specifically, this structural design can facilitate the cutting knife 31 to cut the to-be-cut tow body, so as to improve the cutting efficiency of the cutting knife 31 for cutting the tow body.

The second housing 201 has opposite first and second side surfaces along the first direction. The first direction is the direction from the first housing 1 to the cutting tool assembly 3; Wherein, the first side surface is connected to the cylinder 32 so that the cutting knife 31 extends into the inside of the second housing 201. There is a groove on the side surface of the first housing 1 opposite to the second housing 201.

The hollow part between the first side surface and the second side surface forms the cutting knife channel.

[0036] Specifically, the present application provides an embodiment of a connecting assembly 2, that is, the connecting assembly 2 includes a second housing 201. The cross-sectional shape of the second housing 201 along the first direction is in the shape of a U. The first direction is as Figure 2The direction from the first shell 1 to the cutter assembly 3 shown in the figure, that is, the first direction is a horizontal direction, the second shell 201 has a first side surface and a second side surface opposite to each other along the first direction, the first side surface is detachably connected to the first shell 1 by bolts, the second side surface is detachably connected to the cylinder 32 by bolts, and the cutting knife 31 extends into the second shell 201 through the second side surface and is close to the second side surface.

[0037] A groove is provided on one side of the first shell 1 opposite to the second shell 201. The groove is recessed toward the other side of the first shell 1 away from the one side. When the first shell 1 is connected to the second shell 201, the groove forms a feed channel 9. Figure 2 As shown in the figure, the wire bundle body to be cut enters from the top or bottom and comes out from the bottom or top, wherein the cylinder 32 can drive the cutting knife 31 to pass through the first side and push the wire bundle body to be cut passing through the groove against the abutment block 5 in the accommodating space 4 to achieve the effect of cutting the wire bundle body.

[0038] like Figure 4-Figure 5 As shown, in a specific implementation, the connection component 2 further includes: At least one partition 202 is disposed in the cutter channel and divides the cutter channel into two sub-channels 203 arranged in parallel along the second direction, for allowing one of the cutters 31 to pass through each of the two sub-channels at the same time; Among them, the number of the sub-channels 203, the number of the cutting knives 31, the number of the feeding channels 9, the number of the abutment blocks 5 and the number of the elastic parts 6 are all used to adapt to the number of the tow bodies to be cut and correspond one to one.

[0039] Specifically, in order to enable the device to cut multiple tow bodies to be cut at the same time to improve the cutting efficiency of the device, the present application provides at least one partition 202 in the second shell 201, and divides the second shell 201 into two sub-channels 203 arranged in parallel along the second direction, for each of which a cutting knife 31 passes through at the same time. The second direction is as follows: Figure 2 The horizontal direction shown in , wherein, if the first direction is the X-axis direction of a plane, then the second direction is the Y-axis direction of the plane, the first direction and the second direction are perpendicular to each other in the plane, and if there are at least two partitions 202, then the partitions 202 are arranged in the second shell 201 at intervals along the second direction, and divide the second shell 201 into three sub-channels 203 arranged in parallel along the second direction, for simultaneously passing a cutting knife 31 through each of them.

[0040] It should be noted that a cylinder 32 has multiple telescopic ends, each telescopic end is connected to a cutting knife 31, each cutting knife 31 is located in the corresponding sub-channel 203, and each cutting knife 31 can push the wire bundle body to be cut in the corresponding feed channel 9 against the corresponding abutment block 5 to achieve the effect of cutting the wire bundle body to be cut. Technical personnel in this field can select the number of sub-channels 203, cutting knives 31, feed channels 9, abutment blocks 5 and elastic parts 6 according to actual needs, and this application does not limit it.

[0041] The partition plate 202 and the second housing can be processed into an integral structure by integral casting, or a split structure that is connected in a detachable manner.

The upper plate 207 is provided on the second shell 201 , and the corresponding sub-channels 203 are covered by the first protrusions 208 .

[0043] Specifically, the lower plate 204 is embedded in the corresponding limiting groove 206 to reduce the space in the corresponding sub-channel 203. The upper plate 207 cooperates with the first protrusion 208 to further reduce the space in the corresponding sub-channel 203. This structural design can ensure that the corresponding cutting knife 31 in each sub-channel 203 can move back and forth along a specific route, thereby avoiding the route deviation of the cutting knife 31 when moving in the corresponding sub-channel 203, thereby affecting the cutting efficiency of the wire bundle body to be cut.

[0044] The upper plate 207 and the second shell 201 are detachably connected by bolts, and the upper plate 207 and the first protrusion 208 are processed into an integrated structure by integral casting.

[0046] Specifically, the first protrusion 208 cooperates with the corresponding second protrusion 205 to further reduce the space within the corresponding sub-channel 203, so as to ensure that the corresponding cutting knife 31 in each sub-channel 203 can move back and forth along a specific travel route, thereby avoiding the situation where the cutting knife 31 deviates from the route when traveling in the corresponding sub-channel 203, thereby affecting the cutting efficiency of the wire bundle body to be cut.
