Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This embodiment discloses a transverse wire cutting device, referring to... Figures 1-9 As shown, when installed on a flat knitting machine (such as a glove machine), it can cut off the thread ends during the knitting process, preventing excessively long thread ends from remaining on the fabric surface.

[0033] Reference Figure 1 As shown, the transverse shearing device of this embodiment includes a slide rail 1, a first drive rod 2, a second drive rod 3, and a shearing mechanism. The slide rail 1, the first drive rod 2, and the second drive rod 3 are arranged in parallel along the width direction of the flat knitting machine. Two fixed seats 102 support the slide rail 1 at both ends, allowing the first drive rod 2 and the second drive rod 3 to rotate along their axes while the slide rail 1 is in position.

[0034] The scissor mechanism serves to cut thread ends and mainly includes structures for hooking, cutting, and trimming the thread. The scissor mechanism is slidably connected to slide rail 1 and can be driven by a transverse drive, allowing it to slide and adjust along slide rail 1 in the width direction of the flat knitting machine to correspond to the desired thread cutting position.

[0035] The first drive rod 2 and the second drive rod 3 can be driven to rotate by the first driver 201 and the second driver 301, respectively. Both the first driver 201 and the second driver 301 are motors, capable of controlling the rotation of the first drive rod 2 and the second drive rod 3, respectively. The motors used can be servo motors or stepper motors, as long as they can control the rotation of the corresponding drive rod by the corresponding angle, thereby controlling the action of the scissor mechanism.

[0036] The scissor mechanism includes a base 4, a support block 5, a swing arm 6, a linkage sleeve 7, a sliding block 8, a scissor seat 9, a first blade 10, and a second blade 11.

[0037] The base 4 is fixedly installed on the slide rail 1; the components of the scissor mechanism are supported by the base 4. The transverse drive can be driven by an electric push rod or a belt drive structure driven by a motor, which can drive the base 4 to move laterally, thereby driving the entire scissor mechanism to slide.

[0038] Two support blocks 5 are arranged side by side and fixedly installed on the base 4. A sliding groove 401 is provided on the base 4, and the scissor seat 9 is slidably installed in the sliding groove 401. The first blade 10 is installed on the scissor seat 9, and the second blade 11 is rotatably connected to the scissor seat 9. The first blade 10 and the second blade 11 cooperate with each other to form a scissor-shaped structure.

[0039] The sliding block 8 is installed between two support blocks 5 and can slide back and forth relative to the support blocks 5. A guide groove 1 501 and a guide groove 2 502 are provided on the support blocks 5. Guide blocks 1 801 and 2 802 are fixedly connected to the outer side of the sliding block 8. Guide blocks 1 801 and 2 802 are respectively embedded in the guide grooves 1 501 and 2 502 on both sides, thus supporting the sliding block 8 and allowing it to slide and adjust along the two guide grooves.

[0040] The swing arm 6 and the second blade 11 are linked by the sliding block 8, which can drive the second blade 11 to reciprocate and deflect, thereby realizing the wire cutting action.

[0041] The swing arm 6 has a linkage hole 601 in the middle, and the inner wall of the linkage hole 601 has at least one flat section, which is consistent with the cross-sectional profile of the first drive rod 2. The swing arm 6 can be slidably connected to the first drive rod 2, and the swing arm 6 and the first drive rod 2 can maintain synchronous rotation and linkage through the flat section. A connecting block 402 is fixedly connected to the upper side of the base 4, and the swing arm 6 has an embedding groove 603. When the swing arm 6 is installed, the connecting block 402 is embedded in the embedding groove 603. The connecting block 402 can axially block and limit the swing arm 6, thereby enabling the swing arm 6 to maintain synchronous sliding linkage with the base 4.

[0042] The swing arm 6 has a guide groove 602, which is arranged radially along the first drive rod 2. A linkage shaft 803 is mounted on the sliding block 8, and the linkage shaft 803 is parallel to the first drive rod 2. During installation, the linkage shaft 803 extends laterally through the guide groove 602 and can slide relative to it. During the swinging motion of the swing arm 6, the linkage between the guide groove 602 and the linkage shaft 803 can drive the sliding groove 804 to adjust back and forth.

[0043] A guide groove 4 1101 is provided at the second blade 11. A guide block 2 802 on one side of the sliding block 8 can be embedded in the guide groove 4 1101 and slides and adapts to the guide groove 4 1101. During the movement of the sliding block 8, the guide block 2 802 will slide along the guide groove 4 1101. The direction of the guide groove 4 1101 is set accordingly so that when the sliding block 8 slides, it can drive the rear end of the second blade 11 to slide upward, thereby allowing the second blade 11 and the front end of the first blade 10 to close relative to each other, realizing the wire cutting action. Specifically, the directions of the guide groove 1 501, guide groove 2 502, and guide groove 4 1101 can be specifically set according to the needs of the action.

[0044] In this embodiment, the scissor mechanism further includes a wire clamp 12 and a wire hook 13. The wire hook 13 is fixedly installed on the sliding block 8 and includes a plurality of hook arms 1300, each hook arm 1300 having a hook portion 1301. The hook portion 1301 is specifically an upwardly curved hook-shaped structure.

[0045] The yarn clamp 12 includes a slide rod 1200. A second sliding groove 804 with a front-to-back direction is provided on the upper side of the sliding block 8. The slide rod 1200 is partially embedded in the second sliding groove 804 and can slide and adjust in the front-to-back direction. Two yarn clamping arms 1201 are fixedly connected to the front end of the slide rod 1200. Clamping blocks 1202 are installed at the front end of the clamping arms 1201. The clamping blocks 1202 cooperate with the hook 1301 to clamp the yarn at the hook 1301. The clamping blocks 1202 are made of rubber to prevent the yarn from slipping when clamping.

[0046] Specifically, there are three hook arms 1300, two of which are located on one side of the two blades and the other hook arm 1300 is located on the other side of the two blades. When hooking the yarn, the yarn can be limited on both sides of the blades.

[0047] Reference Figures 2-4As shown, two hook arms 1300 are arranged side by side on one side of the two blades; two clamping arms 1201 are also provided. The two hook arms 1300 and the two clamping arms 1201 are arranged alternately, with the clamping block 1202 at the front end of one clamping arm 1201 extending between the hooks 1301 of the two hook arms 1300. During the clamping process, the clamping block 1202 can extend between the two hooks 1301, and the rubber clamping block 1202 can press against the hooks 1301 on both sides, achieving stable clamping and keeping the yarn in a stable clamped state, avoiding slippage that would affect the cutting of the yarn.

[0048] A limiting block 3 1203 is fixedly connected to the side of the slide rod 1200. A matching limiting groove 805 is provided in the slide block 8. The limiting block 3 1203 is embedded in the limiting groove 805, so that the slide rod 1200 can be limited during the back-and-forth sliding process.

[0049] Reference Figure 8 , Figure 9 As shown, the scissor mechanism also includes a spring 14, which can elastically act on the slide bar 1200, so that during the clamping process, the slide bar 1200 can have an elastic force toward the front end, so that the clamping block 1202 can extend between the two hooks 1301 and maintain the clamping force.

[0050] Specifically, the spring 14 can be a tension spring or a compression spring. In this embodiment, a tension spring is used as an example. A limiting block 4 1204 is fixedly connected to the rear end of the slide rod 1200. The two ends of the spring 14 are respectively connected between the limiting block 4 1204 at the rear end of the slide rod 1200 and the base 4, which can apply a forward elastic force to the slide rod 1200.

[0051] Reference Figure 9 As shown, when the swing arm 6 drives the sliding block 8 to slide forward, the wire clamp 12 extends forward along with the sliding block 8. At the same time, along the direction of the first guide groove 501 and the second guide groove 502, the hook part 1301 can move downward. The hook part 1301 at the front end of the wire clamp 12 can hook the thread. At this time, the tension spring is in an unstretched state. The tension spring can limit the slide rod 1200 of the wire clamp 12. Then, the swing arm 6 drives the sliding block 8 to slide backward. The wire clamp 12 moves backward along with the sliding block 8 and hooks the yarn into the hook part 1301. At the same time, the tension spring is stretched. Under the action of the tension spring, the slide rod 1200 can be elastically restricted. A forward elastic force is applied to the slide rod 1200, so that the clamping block 1202 at the front end of the slide rod 1200 cooperates with the hook part 1301 of the hook arm 1300 to clamp the yarn in the hook part 1301.

[0052] Furthermore, in this embodiment, the scissor seat 9 is slidably mounted on the base 4 and can slide back and forth on the base 4 for adjustment. The slide groove 401 on the base 4 has an arc-shaped structure, with the middle bulging upwards and the front and rear ends bending downwards. The lower part of the scissor seat 9 is integrally fixedly connected to a slider 901, which is slidably connected within the slide groove 401.

[0053] The scissor holder 9 is driven by the second drive rod 3 and the second driver 301, which enables the first blade 10 and the second blade 11 to extend and retract in the front and back direction during the thread cutting process. During the thread cutting process, the first blade 10 and the second blade 11 can extend forward, so that the blade of the scissors can get closer to the yarn, which is beneficial to the smoothness of the thread cutting action.

[0054] Specifically, the linkage sleeve 7 is slidably connected to the second drive rod 3. A second linkage hole 701 is formed on the inner circumference of the linkage sleeve 7. The inner wall of the second linkage hole 701 has a flat, planar surface. The cross-section of the second drive rod 3 is also adapted to the second linkage hole 701. The second drive rod 3 passes through the second linkage hole 701, allowing the linkage sleeve 7 to slide and adjust along the second drive rod 3. The linkage sleeve 7 and the second drive rod 3 maintain synchronous rotational linkage, and it also maintains synchronous sliding linkage with the base 4.

[0055] Limiting block 1 403 and limiting block 2 404 are fixedly connected to the upper side of the base 4. The linkage sleeve 7 is located between limiting block 1 403 and limiting block 2 404. Limiting block 1 403 and limiting block 2 404 can block and limit the axial ends of the linkage sleeve 7, thereby enabling the base 4 and the linkage sleeve 7 to form an axial linkage adjustment.

[0056] Additionally, a first stop 702 and a second stop 703 are fixedly connected to the outside of the linkage sleeve 7. The linkage sleeve 7 is linked to the scissor seat 9 via the first stop 702, which enables the scissor seat 9 to slide back and forth along the slide groove 401. A linkage groove 902 is provided on the side of the scissor seat 9 facing away from the first blade 10. The first stop 702 extends at least partially into the linkage groove 902. During the deflection of the first stop 702, it abuts against the inner wall of the linkage groove 902, which enables the scissor seat 9 to slide, and thus enables the scissor seat 9 to slide back and forth. The second stop 703 can limit the stroke during the rotation of the linkage sleeve 7.

[0057] The slide groove 401 has an arc-shaped structure with an upward bulge in the middle. The scissor seat 9 slides along the slide groove 401, and the first blade 10 can be adjusted up and down with the scissor seat 9. When cutting the yarn, the rotation of the linkage sleeve 7 pushes the scissor seat 9 forward through the stop block 702, and along the direction of the slide groove 401, the front end of the first blade 10 will move downward, so that the blade head can get closer to the yarn. At the same time, guided by the guide groove 1101, the first blade 10 and the second blade 11 can first open to clamp the yarn inside, and then close to close the front ends of the first blade 10 and the second blade 11, thus realizing the yarn cutting action.

[0058] This embodiment also discloses a flat knitting machine, including the horizontal moving thread cutting device as described above. The slide rail 1, the first drive rod 2, and the second drive rod 3 are arranged along the width direction of the flat knitting machine. The scissor mechanism can slide and adjust along the width direction of the flat knitting machine, and can cut off the thread ends to avoid leaving thread ends on the fabric surface during the process.

[0059] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
