Description

Technical Field

[0001] The invention belongs to the technical field of embroidery machines and relates to an embroidery control method of an embroidery machine. Background Art

[0002] Embroidery machines are widely used to embroider various exquisite patterns on embroidery materials (such as embroidery cloth, leather, etc.). During the embroidery process of the embroidery machine, its control device controls the drive mechanism to drive the embroidery needle to continuously move downward and upward, thereby completing the embroidery work.

[0003] When currently used on embroidery machines, the drive mechanism drives the needle downward, carrying the upper thread downward through the embroidery material. Once the needle has reached its proper position, it pulls the leading section of the upper thread below the machine's work surface. Next, the drive mechanism drives the needle upward. During this ascent, the leading section of the upper thread is naturally relaxed. This is because the leading section of the upper thread is not effectively restrained during the needle's ascent. This naturally relaxed state makes it difficult for the upper thread and lower thread to form a stable loop when they interact, pulling the lower thread upward. This, in turn, prevents the embroidery from proceeding properly. This makes it very easy for false embroidery to occur at the start of the embroidery process, severely impacting the quality of the finished product and reducing the efficiency of the embroidery machine. This long-standing problem urgently requires an effective solution. Summary of the Invention

[0004] The purpose of the present invention is to provide an embroidery control method for an embroidery machine to solve the above technical problems.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an embroidery control method of an embroidery machine, comprising the following steps:

[0006] Step S01: When the embroidery machine is started to embroider, the movable blade of the thread trimming mechanism is controlled to swing open. When the movable blade swings into position, the movable blade and the fixed blade are separated from each other, and the thread trimming mechanism is now in the open state.

[0007] Step S02: Control the embroidery needle to move downward, and the embroidery needle moves the front section of the upper thread downward through the embroidery material. When the embroidery needle moves downward to the right position, the front section of the upper thread is located below the work surface of the embroidery machine, and then the embroidery needle is controlled to move upward.

[0008] Step S03: The front section of the upper thread is clamped and fixed. At this time, the front section of the upper thread is in a locked state.

[0009] Furthermore, in step S03: during the rising process of the embroidery needle, when the tip of the embroidery needle is located above the movable blade, the movable blade is controlled to swing toward the fixed blade, and the swing angle of the movable blade is α. When the movable blade swings into place, the movable blade and the locking thread spring clamp the front section of the upper thread, and at this time the front section of the upper thread is in a locked state.

[0010] Furthermore, the swing angle α of the movable blade is 45°-55°.

[0011] Furthermore, the swing angle α of the movable blade is 50°.

[0012] Furthermore, the embroidery machine is provided with an upper thread clamping mechanism. In the step S03 , during the ascending process of the embroidery needle, the upper thread clamping mechanism clamps the front section of the upper thread, and at this time the front section of the upper thread is in a locked state.

[0013] Furthermore, the upper thread clamping mechanism is located below the work surface of the embroidery machine.

[0014] Beneficial Effects of the Invention: Compared with existing technologies, the present embroidery machine control method offers significant advantages. By promptly clamping and securing the leading section of the upper thread during the needle's upward movement, the method effectively resolves the problem of the leading section of the upper thread becoming loose, preventing it from forming a loop with the lower thread and pulling upward. This prevents the occurrence of loose stitches at the beginning of embroidery, significantly improving the quality of embroidery products and making them more refined and durable. Furthermore, the method ensures the smooth operation of the embroidery machine, reduces downtime and rework caused by embroidery failures, improves the machine's operating efficiency, reduces production costs, and enhances its market competitiveness.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Reference Figure 2-4 The embroidery machine is provided with a mounting base 1, on which a rotatable shaft 4 is mounted. The thread cutting mechanism comprises a movable blade 2 and a fixed blade 3. The movable blade 2 is mounted on the upper end of the rotating shaft 4, and the rotating shaft 4 is connected to the output end of the driving mechanism. During operation, the driving mechanism drives the movable blade 2 to swing through the rotating shaft 4 to realize the opening and closing of the movable blade 2. The fixed blade 3 is fixed to the mounting base 1, and the fixed blade 3 is located on the upper side of the movable blade 2. A thread locking shrapnel 5 is also mounted on the mounting base 1, and the thread locking shrapnel 5 is located on the lower side of the movable blade 2. The distance between the thread locking shrapnel 5 and the fixed blade 3 can be adjusted and controlled, thereby adjusting the clamping force of the upper thread and the lower thread.

[0028] Example 1:

[0029] Reference Figure 1 The embroidery control method of the embroidery machine of this embodiment includes the following steps:

[0030] Step S01: When the embroidery machine is started to embroider, the control device of the embroidery machine controls the driving mechanism to move. The driving mechanism drives the movable blade 2 to swing open through the rotating shaft 4. When the movable blade 2 swings into place, the movable blade 2 and the fixed blade 3 are separated from each other. At this time, the thread trimming mechanism is in the open state. Figure 5 As shown, the state of the movable blade 2 is as follows. Figure 6 and Figure 7 The movable blade 2 in the middle dotted line portion;

[0031] Step S02: Figure 8 As shown, one end of the upper thread 7 passes through the threading hole of the embroidery needle 6 and extends from one side of the embroidery needle 6. The part extending from the side of the embroidery needle 6 is the front section 71 of the upper thread 7. The control device of the embroidery machine controls the embroidery needle 6 to move downward, and the embroidery needle 6 moves downward with the front section 71 of the upper thread 7 through the embroidery material. When the embroidery needle 6 moves downward to the right position, the front section 71 of the upper thread 7 is located below the work surface of the embroidery machine. Then the control device of the embroidery machine controls the embroidery needle 6 to move upward.

[0032] Step S03: When the embroidery needle 6 is rising, the tip of the embroidery needle 6 is located above the movable blade 2. Figure 6 The control device of the embroidery machine controls the movable blade 2 to swing toward the fixed blade 3. The swing direction of the movable blade 2 is as follows: Figure 6 As shown by the arrow A in the middle, the swing angle of the movable blade 2 is α. Figure 7 As shown, α is 50°. When the movable blade 2 swings into position, the movable blade 2 and the thread locking spring 5 clamp the front section 71 of the face thread 7. The front section 71 of the face thread 7 is clamped and fixed. At this time, the front section 71 of the face thread 7 is in a locked state.

[0033] In step S03 , when the movable blade 2 swings into position, the face thread 7 will not be cut, because the movable blade 2 and the fixed blade 3 can fully engage to cut the face thread 7 only when the swing angle of the movable blade 2 reaches 70°.

[0034] Example 2:

[0035] The embroidery control method of this embodiment differs from that of Example 1 in that the embroidery machine is equipped with an upper thread clamping mechanism (not shown in the accompanying drawings) located below the machine work surface. Step S03: While the embroidery needle is ascending, the control device issues a command to rapidly activate the upper thread clamping mechanism, clamping the leading section 71 of the upper thread 7. This section 71 is now locked. Because the leading section 71 of the upper thread 7 is clamped, the upper thread 7 can smoothly loop with the lower thread and pull the lower thread upward, ensuring proper embroidery.

[0036] The surface thread clamping mechanism can adopt a variety of structural forms. For example, a clamping claw structure driven by a cylinder can be adopted. The control device drives the opening and closing of the clamping claw by controlling the extension and contraction of the cylinder to achieve the clamping and loosening of the front section 71 of the surface thread 7; an electromagnetic clamping structure can also be adopted to control the clamping and loosening of the front section 71 of the surface thread 7 by the clamping component by controlling the on and off of the electromagnetic force.

[0037] Compared with the existing technology, the embroidery machine control method of the present invention has significant advantages. By promptly clamping and fixing the front section of the upper thread during the needle's ascent, it effectively solves the problem of the upper thread's front section being loose, which makes it difficult for the upper thread and the bottom thread to form a loop and be pulled upward. This avoids the phenomenon of loose embroidery at the beginning of embroidery, greatly improving the embroidery quality and making the embroidery pattern more exquisite and solid. At the same time, it ensures the smooth progress of the embroidery machine's embroidery process, reduces downtime and rework caused by embroidery failures, improves the embroidery machine's operating efficiency, reduces production costs, and enhances the embroidery machine's competitiveness in the market. In actual production, embroidery machines using the embroidery control method of the present invention have a looping rate of the upper thread and the bottom thread close to 100% at the beginning of embroidery.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
