Description

Technical Field

[0001] This utility model relates to the field of tension compensation technology, specifically to an automatic tension compensation device that adapts to the suture material. Background Technology

[0002] Thread tension adjustment equipment is suitable for textile, sewing, or similar thread transmission and processing equipment. In such equipment, the thread tensioning device is a key component to ensure the stability of thread transmission and processing quality. It needs to maintain appropriate tension in accordance with the movement of the thread, while also dealing with various interference factors during the thread transmission process.

[0003] Existing suture tensioning devices include driven adjusting wheels and guide structures. However, the installation positions of these structures are relatively fixed, making it difficult to make flexible fine adjustments based on the state of the suture during high-speed movement. This can easily lead to lateral displacement of the suture, resulting in wheel slippage. Furthermore, while existing devices may be equipped with basic cleaning components, these components lack sufficient fit and positional adjustment flexibility, failing to adhere tightly to the suture surface in real time to remove adhering impurities. They also lack efficient impurity collection and processing structures, allowing impurities to accumulate around the device, affecting the accuracy of tension adjustment and potentially contaminating the equipment. Therefore, an automatic tension compensation device that adapts to the suture material is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic tension compensation device that adapts to the suture material, thereby solving the aforementioned technical problem that easily leads to lateral displacement of the suture, which in turn causes the suture to slip off the roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tension compensation device for adaptive suture material, comprising:

[0006] The base, and the guide input wheel and guide output wheel rotatably connected to the two sides of the front of the base, and the active tension wheel and the driven adjustment wheel are respectively added to the two sides of the center of the front of the base, and the controller and detector are added at the corresponding positions on the front of the base;

[0007] Vertical guide rails and horizontal guide rails are set on both sides of the center of the front of the base. A vertical slider is slidably connected to the center of the inner cavity of the vertical guide rail. A telescopic electric rod and a helical spring are respectively added to the upper and lower parts of the inner cavity of the vertical guide rail. The telescopic end of the telescopic electric rod and the corresponding end of the helical spring are connected to the opposite side of the vertical slider. The active tension wheel is rotatably connected to the front of the vertical slider.

[0008] A lead screw is rotatably connected to the center of the inner cavity of the transverse guide rail, and a transverse slider is threaded on the surface of the lead screw. The driven adjusting wheel is rotatably connected to the front of the transverse slider and coaxially connected to the end of the lead screw to a drive motor. A motor mount is provided between the drive motor and the transverse guide rail.

[0009] Fixed side plates are set on both sides of the base, and suction ports are evenly opened in the center of the fixed side plates. A collection box is installed on the back of the fixed side plates, and the inlet end of the collection box is connected to the outlet end of the suction port, and a suction fan is connected to the outlet end of the collection box.

[0010] A brush plate is set at the upper and lower center of the front side of the fixed side plate, and an electric push rod is installed at the upper and lower center of the front side of the fixed side plate of the brush plate. The telescopic end of the electric push rod is connected to the corresponding brush plate, and bristles are evenly added to the surface of the brush plate.

[0011] The guide input wheel guides the suture into the device, and the guide output wheel guides the suture out of the device; after the controller receives the detector signal, the telescopic electric rod drives the vertical slider to slide along the vertical guide rail, and the helical spring cooperates with the vertical slider to slide along the vertical guide rail. The vertical slider drives the active tension wheel to rotate, and the suture tension is adjusted by the rotation of the active tension wheel.

[0012] After receiving the suture offset signal detected by the detector, the controller drives the motor to rotate the lead screw, which in turn drives the lateral slider to slide along the lateral guide rail. The lateral slider then drives the driven adjustment wheel to rotate, thereby achieving lateral suture correction through the rotation of the driven adjustment wheel.

[0013] The electric push rod drives the brush plate to move towards the seam, and the brush plate drives the bristles to adhere to the seam surface, removing impurities from the seam surface by wiping with the bristles; after the suction fan is started, it absorbs the impurities that fall off the seam surface through the suction port, and the suction port transports the impurities to the collection box for collection.

[0014] Preferably, limiting sides are installed on both sides of the vertical guide rail, and the vertical guide rail is connected to the base by insertion through the limiting sides. The limiting sides can provide lateral restraint for the vertical guide rail, preventing the vertical guide rail from deviating during use and ensuring the stability of the connection between the vertical guide rail and the base.

[0015] Preferably, a fixing seat is added to the back of the base, and side connecting plates are evenly installed on the circumferential surface of the fixing seat, with connecting holes opened on the front of the side connecting plates. The combination design of the side connecting plates and connecting holes enriches the fixing methods of the fixing seat, improves the firmness of the connection between the fixing seat and the mounting surface, and adapts to different installation environments.

[0016] Preferably, a rotating plate is rotatably connected to the front of the fixed base, and a bracket is installed at the center of the rotating plate. The rotational cooperation between the rotating plate and the fixed base provides a basis for the rotational adjustment of the device, enabling subsequent related components to achieve angle adjustment and enhancing the adaptability of the device to different installation scenarios.

[0017] Preferably, the bracket has an overall U-shaped design, and a rotating shaft is rotatably connected to the center of the bracket's inner cavity. The U-shaped design of the bracket provides stable support for the rotating shaft, ensuring smooth and uninterrupted rotation and guaranteeing the reliability of the angle adjustment action.

[0018] Preferably, a fixing plate is mounted on the outer surface of the rotating shaft, and the fixing plate is connected to the center of the back of the base. Through the transmission cooperation between the rotating shaft and the fixing plate, the pitch angle of the base can be flexibly adjusted, further expanding the adaptability range of the device to different wiring directions and installation angles.

[0019] Compared with the prior art, this utility model provides an automatic tension compensation device that adapts to the suture material, which has the following beneficial effects:

[0020] This adaptive suture material automatic tension compensation device has a base with a guide input wheel and a guide output wheel on the front to provide stable guidance for the suture. The active tension wheel is slidably connected to the vertical guide rail via a vertical slider. The vertical slider and the telescopic electric rod and helical spring inside the vertical guide rail, together with the controller and detector, can be flexibly adjusted vertically to adapt to different suture materials, realize automatic tension compensation, and maintain a stable and adaptable suture tension state.

[0021] The driven adjustment wheel slides with the horizontal guide rail through the horizontal slider, and the lead screw is threaded with the horizontal slider and driven by the drive motor. It can make precise horizontal adjustment, correct the lateral offset in the movement of the sewing thread, prevent the wheel from falling off, and improve the stability of the stitching.

[0022] The electric push rod drives the brush plate to adjust its position, so that the bristles fit tightly against the surface of the seam and remove impurities attached to the seam in real time. The suction ports of the fixed side plates on both sides of the base are connected to the collection box on the back. The collection box works with the suction fan to promptly absorb and collect impurities around the seam, preventing impurities from affecting the tension accuracy. The collection box facilitates centralized processing of impurities and avoids accumulation and contamination of the equipment. Attached Figure Description
