[0021] Figure 2 This is another schematic diagram of a sewing device with replaceable needles. Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a sewing device with replaceable needles, which includes a fixing component 100, a driving component 200 and an execution component 300.

[0027] Specifically, the drive assembly 200 is fixedly disposed on one side of the fixed assembly 100, including a first drive member 201 and a second drive member 202 fixedly disposed below the first drive member 201. The execution assembly 300 includes a limiting block 301 and a piercing member 302 detachably connected to the second drive member 202, the piercing member 302 cooperating with the limiting block 301. The fixed assembly 100 is disposed at the top of the device and connected to the robotic arm. The first drive member 201 drives the execution assembly 300 and the second drive member 202 to move up and down as a whole until the bottom end of the limiting block 301 is in contact with the fabric surface. After the bottom end of the limiting block 301 is in contact with the fabric surface, the limiting block 301 no longer moves.

[0028] Furthermore, the second driving component 202 drives the piercing component 302 to move up and down reciprocally, and the piercing component 302 passes through the limiting block 301 to continuously perform sewing operations on the fabric.

[0029] The puncture element 302 can be replaced according to the fabric density and knitting method. Different puncture elements 302 can be replaced simply by unscrewing the screws that fix the puncture element 302 and the second drive element 202.

[0030] In use, first fix the top of the first drive component 201, then start the first drive component 201. The execution component 300 and the second drive component 202 move downward together until the bottom of the limit block 301 is in contact with the surface of the fabric. At this time, fix the limit block 301 again, the first drive component 201 stops working, and the second drive component 202 starts, driving the piercing component 302 to move up and down reciprocally to perform sewing operations on the fabric. When the thickness of the fabric changes, the position of the limit block can be adjusted to adjust the depth of the piercing component 302 into the fabric. When the density of the fabric changes, the piercing component 302 can be directly replaced to adapt to different fabrics.

[0031] Example 2

[0032] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. This embodiment provides a sewing device with replaceable needles, which includes a fixing component 100, a driving component 200 and an execution component 300.

[0033] Specifically, the fixing assembly 100 includes a flange 101, a fixing plate 102 fixedly disposed at the lower center of the flange 101, a reinforcing plate 103 fixedly disposed on both sides of the fixing plate, and a mounting plate 104. The upper side of the flange 101 is connected to the robotic arm, the reinforcing plate 103 is perpendicular to the fixing plate 102, and the drive assembly 200 and the execution assembly 300 are both disposed on one side of the mounting plate 104. The fixing assembly 100 also includes a top plate 105 disposed on the upper side of the first drive member 201, and the top plate 105 is fixedly connected to the upper side of the mounting plate 104 and the top end of the first drive member 201.

[0034] Furthermore, a connecting block 201a is fixedly disposed at the bottom of the first driving member 201, and a fixing block 303 and a second driving member 202 are fixedly disposed on one side of the connecting block 201a. The fixing block 303 is disposed on one side of the mounting plate 104 and a limiting block 301 is fixedly disposed on its outer side. At least one through hole 301a is opened at the bottom of the limiting block 301. The actuating component 300 and the second driving member 202 are disposed on the lower side of the connecting block 201a, and the second driving member 202 is tightly attached to the outer side of the fixing block 303.

[0035] Preferably, a groove is provided on one side of the mounting plate 104, and part of the fixing block 303 cooperates with the groove. When the fixing block 303 moves downward under the action of the first driving member 201, the fixing block 303 also slides in the groove until it reaches the bottom of the groove and gets stuck.

[0036] Preferably, the piercing member 302 includes a mounting base 302a and a piercing needle 302b that cooperates with the mounting base 302a. The mounting base 302a is detachably connected to the second driving member 202. The piercing needle 302b penetrates the fabric through the through hole 301a. There are three through holes 301a evenly arranged, each corresponding to a piercing needle 302b.

[0037] Preferably, the second driving member 202 is provided with at least one push rod. The bottom of the push rod is fixedly connected to the connecting block 202ab. One side of the connecting block 202ab engages with the second driving member 202, and the other side of the connecting block 202ab engages with the puncture member 302. The mounting base 302a is detachably connected to the connecting block 202ab. When it is necessary to replace a different puncture needle 302b, the entire puncture member 302 needs to be replaced together. The screws fixing the puncture member 302 and the connecting block 202ab are unscrewed, and then the entire puncture member 302 is removed and replaced with another puncture member 302. After the second driving member 202 is activated, the push rod moves up and down, driving the connecting block 202a to move up and down, thereby driving the puncture needle 302b to reciprocate up and down.

[0038] Preferably, the fixing block 303 has at least one first fixing hole 303a on both sides, and the limiting block 301 has at least one second fixing hole 303b on both sides. The diameters of the first fixing hole 303a and the second fixing hole 303b are equal. The limiting block 301 is used to adjust the distance between the entire device and the fabric. When the distance is too large, the screws fixing the fixing block 303 and the limiting block 301 can be removed, the second fixing hole 303b of the limiting block 301 can be aligned with the first fixing hole 303a on the lower side of the fixing block 303, and then the screws can be passed through the first fixing hole 303a and the second fixing hole 303b to fix it.

[0039] Preferably, the first driving member 201 and the second driving member 202 are electric push rods that drive the entire device to move.

[0040] When in use, first open the first drive component 201, and all the structures fixedly connected to the bottom of the first drive component 201 move downward together until the bottom end of the limiting block 301 is in contact with the fabric surface. The first drive component 201 and the limiting block 301 remain stationary, and the second drive component 202 drives the push rod to move up and down, thereby driving the needle 302b to move up and down reciprocally to sew the fabric.

[0041] Example 3

[0042] Reference Figure 1 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a sewing system with replaceable needles.

[0043] Specifically, a sewing system with replaceable needles includes a sensor module, a power supply module, and an execution module. A control module is electrically connected to the execution module, controlling the movement of the electric linear actuator and coordinating the movements of each module. The sensor module provides real-time feedback, such as position, force, and speed information, to ensure precise movement of the electric linear actuator. The power supply module provides the necessary power to the electric linear actuator and the control module.

[0044] Furthermore, the control module controls the first driving component 201 to move up and down to adjust the height of the limiting block 301, and the control module controls the push rod of the second driving component 202 to move up and down reciprocally to sew the fabric.

[0045] In summary, the beneficial effects of this utility model are as follows:

[0046] 1. By setting the limiting block, the height of the entire device from the fabric can be adjusted, which can be used to sew fabrics of different thicknesses, making the sewing process more stable and reducing uneven sewing or irregular stitches caused by improper height.

[0047] 2. Because the needle components are replaceable, when the needles wear or are damaged, it is not necessary to replace the entire sewing device; only the individual needle section needs to be replaced. This not only saves costs but also extends the overall lifespan of the equipment. Simultaneously, it reduces downtime during maintenance and improves work efficiency.

[0048] 3. By setting up the first and second driving components, the overall work efficiency and ease of operation are improved.
