Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to an independent mounting device for the main shaft encoder of a sewing machine. Background Technology

[0002] A sewing machine is a mechanical device used to join fabrics, leather, or other materials together with stitches. It is typically driven electrically or manually and completes the sewing task through the interaction of the needle, thread, and fabric. The sewing machine's spindle encoder is an electronic component used to precisely control the rotational position and speed of the sewing machine's spindle (usually a motor-driven rotating shaft). Its function is to convert the spindle's rotational motion into digital signals, which are then monitored and adjusted in real time by the machine's control system (such as a PLC or microcontroller). This helps to achieve more precise sewing operations, such as automatic stopping, positioning, speed adjustment, and optimization of sewing quality.

[0003] The independent mounting device for the main shaft encoder of a sewing machine is a structural component used to separate the main shaft encoder from the sewing machine main shaft. Existing independent mounting devices for the main shaft encoder of sewing machines lack a precise adjustment mechanism, which may lead to misalignment between the encoder and the main shaft, thus affecting signal acquisition accuracy. The lack of effective support and fixing devices may cause the encoder to vibrate or shift position during high-speed operation, thereby reducing system stability. Therefore, this invention proposes an independent mounting device for the main shaft encoder of a sewing machine to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an independent mounting device for the spindle encoder of a sewing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sewing machine spindle encoder independent mounting device includes an encoder body and a fixed base. An adjusting base is fixed to the front side of the encoder body and slides up and down within the fixed base. The fixed base is provided with a sliding groove corresponding to the adjusting base. Side seats are rotatably connected to both the left and right sides of the encoder body. A second support rod is provided between the side seat and the encoder body. A sliding sleeve seat is provided on the front side of the side seat and slides left and right. A first support rod is rotatably connected to the upper and lower ends of the sliding sleeve seat. A patch is fixed to the outer end of the first support rod.

[0007] Preferably, a support block is fixed to the inner end of the side seat, the rear side of the side seat is rotatably connected to one end of the second support rod, and a slider is rotatably connected to the other end of the second support rod.

[0008] Preferably, the encoder body is provided with a protective shell, and the shell has grooves for corresponding sliders on both the left and right sides. The sliders slide back and forth in the grooves, and the grooves are provided with compression springs for the corresponding sliders.

[0009] Preferably, a screw is rotatably connected to the front side of the side seat, the screw is threadedly connected to the sliding sleeve seat, and a knob is fixed to the outer end of the screw.

[0010] Preferably, a torsion spring is provided at the junction of the first support rod and the sliding sleeve seat, and a limiting block corresponding to the first support rod is fixed on both the upper and lower sides of the inner end of the side seat.

[0011] Preferably, the encoder body housing is fitted with a sliding sleeve ring that slides back and forth, and the front left and right sides of the sliding sleeve ring are provided with insert blocks, and the outer ends of the two side seats are provided with slots corresponding to the insert blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of the adjusting seat and sliding groove, enables the encoder to be precisely and steplessly adjusted to the ideal docking position with the sewing machine spindle. This adjustment function ensures that the encoder can adapt to changes in different working conditions and guarantees the accuracy of signal acquisition. The design of the sliding sleeve ring and the plug block allows the encoder to be easily adjusted in angle during installation or maintenance, providing good operational flexibility. The screw adjustment mechanism can further finely adjust the position of the encoder to ensure that it remains stable during operation.

[0014] 2. Through precise adjustment and a stable support structure, the encoder body of this utility model can closely fit the sewing machine spindle and vibrate synchronously, ensuring high accuracy of data acquisition. The support rods and adjustment mechanism on both sides ensure the stability of the encoder in the horizontal and vertical directions, effectively avoiding the impact of vibration on data accuracy, and ensuring that the sewing machine system can continuously provide accurate rotation data while working efficiently. The support system effectively avoids positional displacement caused by mechanical vibration and external forces.

[0015] In summary, this invention not only optimizes the installation and adjustment process of sewing machine encoders, but also significantly improves the stability, reliability, and ease of maintenance of the device. The overall structure is simple yet comprehensive, making it suitable for sewing machine systems that operate at high efficiency for extended periods, ensuring accurate data acquisition and system stability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An independent mounting device for a sewing machine spindle encoder includes an encoder body 1 and a fixed base 2. An adjusting seat 3 is fixed to the front side of the encoder body 1. The adjusting seat 3 slides up and down within the fixed base 2. The fixed base 2 is provided with a sliding groove corresponding to the adjusting seat 3. The fixed base 2 is fixed at the position of the sewing machine spindle. The up and down position of the adjusting seat 3 within the fixed base 2 is adjusted so that the encoder body 1 corresponds to the sewing machine spindle. This allows the sewing machine spindle to be connected to the encoder body 1 by mechanical or electronic means, ensuring that the sewing machine control system can accurately acquire rotation data. The encoder body 1 and the motor are located on opposite sides of the sewing machine. Compared with the prior art where the encoder is placed inside the motor, this structure makes installation and maintenance more convenient and reduces the impact of dust generated during motor operation on the encoder's operation.

[0023] Furthermore, side seats 4 are rotatably connected to both sides of the encoder body 1. A second support rod 8 is provided between the side seat 4 and the encoder body 1. A support block 15 is fixed to the inner end of the side seat 4. The rear side of the side seat 4 is rotatably connected to one end of the second support rod 8, and the other end of the second support rod 8 is rotatably connected to a slider 11. A protective shell is provided on the outside of the encoder body 1. Slide grooves 16 corresponding to the sliders 11 are opened on both the left and right sides of the shell. The sliders 11 slide back and forth in the slide grooves 16, and compression springs corresponding to the sliders 11 are provided in the slide grooves 16. A sliding sleeve ring 6 is fitted on the outside of the outer shell of the encoder body 1. The sliding ring 6 has a plug 12 on the left and right sides of the front side, and the outer ends of the two side seats 4 are provided with slots 13 corresponding to the plug 12. Pulling the sliding ring 6 on the outer shell of the encoder body 1 backward causes the left and right plugs 12 on the front side to disengage from the slots 13 of the side seats 4, and the two side seats 4 lose their rotation restriction. The slider 11 in the sliding groove 16 is pushed forward by the spring force of the compression spring. The forward slider 11 causes the side seat 4 connected to the outer end to rotate through the support rod 2 8, from the original vertical to the vertical of the encoder body 1, and the inner end support block 15 of the side seat 4 will be tightly attached to the left and right outer sides of the fixed seat 2.

[0024] Furthermore, a sliding sleeve seat 7 is provided on the front side of the side seat 4, which can slide left and right. Support rods 5 are rotatably connected to the upper and lower ends of the sliding sleeve seat 7. A block 9 is fixed to the outer end of each support rod 5. A torsion spring is provided at the junction of the support rod 5 and the sliding sleeve seat 7. Limiting blocks 14 corresponding to the support rods 5 are fixed to the upper and lower sides of the inner end of the side seat 4. A screw 10 is rotatably connected to the front side of the side seat 4. The screw 10 is threadedly connected to the sliding sleeve seat 7, and a knob is fixed to the outer end of the screw 10. Rotating the screw 10 via the knob causes the threaded sliding sleeve seat 7 to move towards the inner end of the side seat 4 until both support rods 5 completely slide out of the rotation restriction range of the limiting blocks 14. The two support rods 5 are subjected to the action of torsion springs and the rotation restriction of the limit block 14. They will rotate 45 degrees and continuously push the sliding sleeve seat 7 towards the middle encoder body 1 through the rotating screw 10. The pad 9 at the outer end of the support rod 5 will be close to the left and right outer sides of the fixed seat 2 and fixed to the adjustment position of the encoder body 1 on the fixed seat 2. The two support rods 8 on both sides ensure the horizontal stability of the encoder body 1. The pad 9 at the inner end of the four support rods 5 on both sides is attached to the surface of the fixed seat 2 to ensure the horizontal stability of the encoder body 1 in the vertical direction. This ensures that the encoder body 1 is closely attached to the sewing machine and vibrates at the same frequency.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
