Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to a bird nest prevention device for a template machine. Background Technology

[0002] The "bird's nest" problem in sewing machines is a common challenge during the sewing process. During the initial lockstitch formation, the needle may pull a loose thread from the previous thread cut into the fabric, where it becomes tangled and intertwined with the bobbin thread. Because the lengths of the pulled-down threads vary, the area of ​​tangling on the bottom of the fabric differs, resulting in a bird's nest-like clump of thread that severely affects the appearance and quality of the finished product.

[0003] To address the "bird's nest" problem at the start of a sewing machine, current technology involves grasping the top thread during the initial stitching stage, sewing a few stitches, and then releasing it. However, this method cannot cut the top thread, resulting in excessively long residual thread ends that still affect the stitch appearance and do not completely solve the problem. Some anti-bird's nest devices are also bulky, easily interfering with the needle and making it difficult to precisely control the timing of thread cutting, resulting in long residual thread ends. Furthermore, the cut thread ends cannot be cleaned up promptly, affecting the reusability of the anti-bird's nest device and the cleanliness of the sewing fabric. Currently, the hook portion of existing anti-bird's nest devices is too small and the hook tip is short and flat, making it easy for the thread loop to fail to catch, leading to the loop falling off or loosening and causing the "bird's nest" phenomenon. In addition, existing anti-bird's nest devices have limitations in installation location and are not flexible enough, making them unsuitable for different types of sewing machines. Utility Model Content

The hook needle of the hook-type component is long and hook-shaped and extends out of the front end of the connecting seat. The rear end of the connecting seat is provided with a first power source, and the telescopic end of the first power source is connected to the rear end of the hook-type component through a sliding block. The front end of the connecting seat is also provided with a clamping component, which is placed on the top surface of the rod of the hook-type component. The clamping component and the hook needle of the hook-type component work together to clamp the line loop.

[0005] Furthermore, the bottom surface of the connecting seat is provided with several through holes, and the bottom surface of the connecting seat is also provided with a second power source. The second power source is connected to the connecting seat through a connecting plate. The telescopic end of the second power source passes through the through holes on the bottom surface of the connecting seat and leads to the sliding groove and extends to the front end face of the sliding block.

[0006] Furthermore, a third threaded through hole is provided on the bottom surface of the connecting seat near the first power source, and the connecting plate is connected to the third threaded through hole on the bottom surface of the connecting seat by bolts.

[0007] Furthermore, a first threaded through hole is provided on the tail end wall of the connector, the first power source passes through the first threaded through hole and is threadedly fastened to the connector, and a bolt is also provided on the front end face of the first threaded through hole.

[0008] Furthermore, the side of the connecting seat is provided with a second threaded through hole, and the end of the first connecting block near the connecting seat is provided with a first waist hole.

The first connecting block can move around the bolt, so that the position of the connecting seat and the first connecting block can be adjusted and connected. The end of the first connecting block away from the connecting seat is provided with a second waist hole.

[0009] Furthermore, the second connecting block has a fifth threaded through hole at one end near the first connecting block, and the bolt passes through the second waist hole of the first connecting block and the fifth threaded through hole of the second connecting block. The second connecting block can move around the bolt, so that the positions of the first connecting block and the second connecting block can be adjusted and connected. The second connecting block has a third waist hole at one end away from the first connecting block.

[0010] Furthermore, the end of the clamping member near the connecting seat is provided with a fourth waist hole, which is connected to the fourth threaded through hole of the connecting seat by a bolt. The clamping member can move around the bolt, so that the position of the clamping member and the connecting seat can be adjusted and connected.

[0011] Furthermore, the hook portion of the hooking member includes a hook tip, a hook groove connected to the hook tip, and a hook body connected to the hook groove.

Detailed Implementation

[0023] 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.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model discloses a bird nest prevention device for a template machine, as shown in the attached figure. Figure 1 and attached Figure 2 As shown, the device includes a connecting seat 1 and a hook member 2 connected to the front end of the connecting seat 1. The top surface of the connecting seat 1 has a sliding groove 11. The rod portion 22 and the rear end portion 23 of the hook member 2 are placed in the sliding groove 11. The hook needle portion 21 of the hook member 2 is long and hook-shaped and extends out of the front end face of the connecting seat 1. The tail end of the connecting seat 1 is provided with a first power source 3. The telescopic end of the first power source 3 is connected to the rear end portion 23 of the hook member 2 through a sliding block 4. The front end of the connecting seat 1 is also provided with a clamping member 5. The clamping member 5 is placed on the top surface of the rod portion 22 of the hook member 2. The clamping member 5 and the hook needle portion 21 of the hook member 2 cooperate to clamp the line loop. The side of the connecting seat 1 is connected to a first connecting block 9. The first connecting block 9 is connected to a second connecting block 10.

[0026] It should be further explained that the first power source 3 is a linear cylinder, the cylinder body of which is fixed to the tail end of the connecting seat 1 by bolts, the telescopic end is hinged to the rear end of the sliding block 4 by a pin, the sliding block 4 is fastened to the rear end 23 of the hook member 2 by countersunk bolts, and the sliding block 4 slides in cooperation with the inner wall of the sliding groove 11 to ensure that the hook member 2 moves smoothly along the axial direction of the sliding groove 11.

[0027] Furthermore, the bottom surface of the connecting seat 1 is provided with a plurality of through holes 12, and the bottom surface of the connecting seat 1 is also provided with a second power source 6. The second power source 6 is connected to the connecting seat 1 through a connecting plate 7. The telescopic end of the second power source 6 passes through the through holes 12 on the bottom surface of the connecting seat 1 and leads to the sliding groove 11 and extends to the front end face of the sliding block 4.

[0028] It should be further explained that the second power source 6 is a miniature electric push rod, whose cylinder body is bolted to the bottom surface of the connecting seat 1 through the connecting plate 7. The telescopic end is fitted with a polyurethane buffer sleeve. Preferably, a brass wear-resistant sleeve is embedded in the inner wall of the through hole 12. The telescopic end of the second power source 6 extends through the wear-resistant sleeve to the corresponding position of the front end of the sliding block 4. When the hook part 2 moves forward to the hooking position, the telescopic end of the second power source 6 extends and presses against the sliding block 4, which, together with the first power source 3, realizes the positioning of the hook part 2 and improves the vibration resistance of the hook needle part 21 when hooking the line.

[0029] During the initial sewing stage, the first power source 3 is activated. The telescopic end of the first power source 3 extends along the length of the connecting seat 1 to a preset distance. During this process, the telescopic end of the first power source 3 drives the sliding block 4, which is rigidly connected to it, to move smoothly along the preset sliding groove 11 of the connecting seat 1 a corresponding distance. The guiding effect of the sliding groove 11 can prevent the sliding block 4 from deviating, ensuring accurate movement trajectory. Furthermore, through the linkage structure between the sliding block 4 and the hooking member 2, the hook needle part 21 of the hooking member 2 is driven to move synchronously along the length of the connecting seat 1, so that the hook needle part 21 accurately reaches the loop formation area below the needle, stably hooking the loop during sewing. Preferably, the hook needle part 21 of the hooking member 2 is designed with a long V-shaped acute angle, and its opening angle is controlled within the range of 30°-45°, which is adapted to the diameter of the loop formed after the needle penetrates the sewing material, and can quickly wrap the loop. The tip is treated with high frequency quenching to maintain its sharpness so as to easily pierce the inside of the loop and avoid the loop from slipping due to tip blunting. Meanwhile, the thickness of the hook part 21 is controlled within the range of 0.3-0.5mm, which can reduce interference with the sewing fabric fibers and the needle bar. Especially when sewing multiple layers of thick materials, it can reduce the resistance of hooking the thread and ensure the continuity of the thread loop hooking action.

[0030] Furthermore, after the hook part 21 of the hooking member 2 hooks the loop, the telescopic end of the first power source 3 is reset, thereby causing the sliding block 4 to move a certain distance in the opposite direction along the sliding groove 11, and further causing the hook part 21 of the hooking member 2 to move along the connecting seat 1. After moving a certain distance in the opposite direction along the length, the hook part 21 of the hooking member 2 and the hooked loop move to the bottom of the clamping member 5. At this time, the hook part 21 of the hooking member 2 and the clamping member 5 work together to clamp the loop.

[0031] After the hook part 21 of the hook component 2 clamps the thread loop, the sewing machine enters the normal sewing stage. At this time, the control system synchronously triggers the second power source 6 to start working. The telescopic end of the second power source 6 extends axially along the through hole 12 preset on the bottom surface of the connecting seat 1. The inner diameter of the through hole 12 and the outer diameter of the telescopic end are clearance-fitted, which provides precise guidance for the telescopic end, avoids radial swaying, and reduces motion friction. After the telescopic end of the second power source 6 passes through the through hole 12, it enters the sliding groove 11 and finally extends to the front end face of the sliding block 4 and abuts against it. At this time, the telescopic end of the second power source 6 achieves rigid limitation of the sliding block 4 through end face contact, avoiding the risk of the hook component 2 colliding with the high-speed sewing machine needle bar due to excessive extension, and at the same time avoiding the thread loop from falling off or the stitch from deforming due to the displacement of the hook component, providing a stable mechanical state support for subsequent stitch formation.

[0032] After the sewing machine finishes sewing the fabric, the sewing machine's main control system first triggers the second power source 6 to move. Its telescopic end retracts axially along the through hole 12 on the bottom surface of the connecting seat 1 and gradually moves completely out of the through hole 12. At the same time, the telescopic end of the first power source 3 gradually extends along the length of the connecting seat 1, in the opposite direction to the extension direction when sewing begins. Through the rigid connecting piece, it drives the sliding block 4 to move in the opposite direction along the sliding groove 11. The guiding effect of the sliding groove 11 ensures that the sliding block 4 moves accurately and avoids deviation. This drives the hook part 2 to move synchronously, so that the hook part 21 of the hook part 2 gradually gets out of the clamping range of the clamping part 5 and finally extends completely out of the clamping part 5. The stitch naturally loosens due to the loss of the constraint of the hook part 2, achieving precise thread loosening. After the thread loosening action is completed, the first power source 3 and the second power source 6 are reset in sequence according to the preset timing, thus completing the sewing of the fabric. Repeating the above steps can prevent the thread loops from piling up under the needle bar to form a bird's nest structure during the sewing process, and at the same time ensure that there are no excess threads or stretching deformations at the beginning and end of the stitches of each piece of fabric, ultimately achieving a beautiful and neat overall stitch.

[0033] The connecting seat 1 has a third threaded through hole 15 on its bottom surface near the first power source 3. One end of the connecting plate 7 is connected to the third threaded through hole 15 on the bottom surface of the connecting seat 1 by bolts, and the other end of the connecting plate 7 is fixedly mounted on the second power source 6. After the second power source 6 is installed on the connecting plate 7, the telescopic end of the second power source 6 will be aligned with the through hole 12 of the connecting seat 1. After clamping the thread ring, the telescopic end of the second power source 6 is activated to pass through the through hole 12 on the bottom surface of the connecting seat 1 and lead to the front end of the sliding block 4, thereby limiting the sliding block 4 and preventing the hook 2 from extending excessively and hitting the sewing machine needle bar.

[0034] In addition, two sets of third threaded through holes 15 are provided, each set including two third threaded through holes 15 distributed along the width direction of the connecting seat 1. In actual use, the end of the connecting plate 7 away from the second power source 6 can be connected to any set of third threaded through holes 15 as needed to adjust the position of the second power source 6. Furthermore, the connecting seat 1 also has three through holes 12, ensuring that after the position is adjusted, the telescopic end of the second power source 6 can still pass through the through holes 12 to reach the corresponding position in the sliding groove 11, thereby allowing the telescopic end of the second power source 6 to limit the sliding block 4 at different positions in the sliding groove 3.

[0035] Furthermore, the tail end wall of the connecting seat 1 is provided with a first threaded through hole 13, the first power source 3 passes through the first threaded through hole 13 and is threadedly fastened to the connecting seat 1, and a bolt 8 is also provided at one end of the first threaded through hole 13. The bolt 8 prevents the connecting seat 1 from being loosened from the first power source 3, so that the connecting seat 1 and the first power source 3 are more tightly connected.

[0036] As attached Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the connecting seat 1 has two second threaded through holes 14 on each of its left and right sides near the first power source 3. Bolts pass through the second threaded through holes 14 to connect the connecting seat 1 to the first connecting block 9. The first connecting block 9 has two first waist holes 91 spaced apart near the connecting seat 1. Each first waist hole 91 consists of a central rectangular hole and two semi-circular holes at both ends. During installation, the bolt is first installed in one of the first waist holes 91. After the first connecting block 9 is rotated or moved by a certain angle around the bolt in the first waist hole 91 to determine the required position, a bolt is added to the other first waist hole 91 for tightening, thereby fixing the first connecting block 9 and the connecting seat 1 after adjusting the angle.

[0037] The first connecting block 9 has two second waist holes 92 spaced apart at its end away from the connecting seat 1. One second waist hole 92 consists of a central rectangular hole and two semi-circular holes at both ends, while the other second waist hole 92 consists of a central arc-shaped hole and two semi-circular holes at both ends. The second connecting block 10 has two sets of paired fifth threaded through holes 101 at its end near the first connecting block 9. A bolt is installed in one of the threaded through holes 101 in one set of fifth threaded through holes 101. The second connecting block 10 is then rotated or moved around the bolt to determine the desired position. Afterward, a bolt is installed in one of the threaded through holes 101 in the other set of fifth threaded through holes 101 in the second connecting block 10 to fix the first connecting block 9 and the second connecting block 10 after adjusting the angle. Furthermore, the second connecting block 10 has two third waist holes 102 at its end away from the first connecting block 9. One third waist hole 102 consists of a central rectangular hole and two semi-circular holes at both ends, while the other third waist hole 102 consists of a central arc-shaped hole and two semi-circular holes at both ends. These are used to adjust the position when installed on different models of sewing machines. Preferably, both the first connecting block 9 and the second connecting block 10 are L-shaped, which makes them easy to install and flexible to adjust, allowing the anti-bird nest device to be installed on different models of sewing machines.

[0038] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the clamping member 5 has two fourth waist holes 51 at one end near the connecting seat 1, which are connected to the fourth threaded through hole 16 of the connecting seat 1 by bolts. Each fourth waist hole 51 consists of a central rectangular hole and two semi-circular holes at both ends. During installation, the bolts are placed in the fourth threaded through hole 16 and the fourth waist holes 51. The position of the clamping member 5 is moved according to actual needs, and then the bolts are tightened to fix the clamping member 5 to the connecting seat 1. This allows the hook part 21 of the hooking member 2 to engage with the clamping member 5 after moving different distances to clamp the line loop.

[0039] As attached Figure 7As shown, the hook part 21 of the hooking component 2 includes a hook tip 211, a hook groove 212 that is connected to the hook tip 211 by an arc transition, and a hook body 213 that is smoothly connected to the hook groove 212. Preferably, the tip edge of the hook tip 211 is designed as an arc shape and is mirror polished, which can quickly and accurately pierce into the loop formed by the needle and prevent the loop from slipping out. The hook groove 212 is connected to the rear end of the hook tip 211 by an arc transition, and the opening width narrows to form a gradual arc of "wide on the outside and narrow on the inside". The inner side of the hook groove is mirror polished to eliminate processing burrs. When the thread is inserted, it can prevent the fibers from being scratched or frayed, ensuring that the stitch strength is not damaged. At the same time, with the depth space at the bottom of the groove, it can stably accommodate the loop and prevent the loop from being excessively squeezed and deformed. After the hook body 213 smoothly connects with the hook groove 212, its axis forms an inclined angle with the rod portion 22 of the hook member 2, adapting to the rotation trajectory below the sewing machine, ensuring that the hook can drive the thread loop to form a chain stitch after hooking the thread. Furthermore, the rear end portion 23 of the hook member 2 is provided with a threaded through hole.

[0040] As attached Figure 1 Appendix Figure 2 and attached Figure 8 As shown, the sliding block 4 has a first connecting hole 41 at one end near the rear end 23 of the hook member 2. The rear end 23 of the hook member 2 is connected to the first connecting hole 41 of the sliding block 4 by a bolt. The sliding block 4 has a second connecting hole 42 at one end away from the rear end 23 of the hook member 2. The telescopic end of the first power source 3 is fastened to the second connecting hole 42 of the sliding block 4 by a thread. The rear end face of the second connecting hole 42 of the sliding block 4 is fastened with a bolt to prevent the sliding block 4 from detaching from the first power source 3, so that the sliding block 4 and the first power source 3 are more securely fixed.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
