[0002] Reeding is the process of drawing in the warp, which is the last process in the warp preparation process. The task of drawing in the warp is to pass the warp yarn on the weaving beam through the dropper, heald and reed according to the requirements of the fabric in a certain pattern, so as to form a shed during weaving and introduce the weft yarn to weave the required fabric.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0033] like Figure 1-2 As shown, the color-dyed warp intelligent reeding device comprises: a mounting frame 1 and a control device; a warp position adjusting mechanism 3, a heald frame 4 and a reeding mechanism 5 are mounted on the mounting frame 1; a warp clamping mechanism 2 is mounted on the warp position adjusting mechanism 3; the warp clamping mechanism 2 is used for clamping the warp; the warp position adjusting mechanism 3 is used for adjusting the position of the warp; the reeding mechanism 5 is used for driving the warp on the warp clamping mechanism 2 to pass through the heald frame 4; the control device is used for controlling the operation of the entire color-dyed warp intelligent reeding device except itself.

[0034] like Figure 3As shown, the warp position adjustment mechanism 3 includes: a lifting platform 301 and an electric lead screw device 302; the lifting platform 301 is vertically slidably mounted on the mounting frame 1, and is driven by the electric lead screw device 302 fixedly mounted on the mounting frame 1; as a specific implementation of this embodiment, two limit columns and two electric lead screw devices 302 are vertically fixedly mounted on the mounting frame 1; the lifting platform 301 is vertically slidably mounted on the two limit columns and the two electric lead screw devices 302.

[0035] A horizontal slide 303 is horizontally slidably installed on the lifting platform 301, and is driven by an electric screw device 304 fixedly installed on the lifting platform 301; as a specific implementation of this embodiment, a guide rail in the horizontal direction is provided on the lifting platform 301; the horizontal slide 303 is horizontally slidably installed on the guide rail, and is driven by an electric screw device 304 fixedly installed on the lifting platform 301; a warp clamping mechanism 2 is installed on the horizontal slide 303.

[0036] Different textile requirements require different sizes and structures of the heald frames 4. In order to make the warp yarns correspond to different heald frames 4, the warp yarn clamping mechanism 2 needs to drive the warp yarns to move; the warp yarn clamping mechanism 2 is driven to move vertically up and down by the lifting platform 301, and the warp yarn clamping mechanism 2 is driven to move horizontally by the horizontal slide 303, so that the warp yarn clamping mechanism 2 drives the warp yarns to move to the correct position; by setting the warp yarn position adjustment mechanism 3, the device can be applied to more heald frames 4, thereby increasing the scope of application of the device.

[0037] Specifically, Figure 2-3 As shown, the warp yarn clamping mechanism 2 includes: a wire clamp 201 and a wire clamp fixing frame 202; the lower end of the wire clamp fixing frame 202 is fixedly installed on the horizontal slide 303, and the upper end is fixedly installed with the wire clamp 201; the wire clamp 201 is used to fix the warp yarn; as a specific implementation of this embodiment, the wire clamp 201 is provided with an upper wire clamping body and a lower wire clamping body; the upper wire clamping body is located above the lower wire clamping body; by clamping the warp yarn at two positions, it is more convenient for the reeding mechanism 5 to drive the warp yarn to pass through the heald frame 4.

[0038] Specifically, Figure 4-6 As shown, the heald frame 4 is vertically slidably installed on the mounting frame 1 and corresponds to the warp clamping mechanism 2; as a specific implementation of this embodiment, a fixed limit frame and a sliding limit frame are provided on the mounting frame 1; the sliding limit frame is horizontally slidably installed on the mounting frame 1, and is driven by an electric lead screw device 3 fixedly installed on the mounting frame 1; the heald frame 4 is vertically slidably installed between the fixed limit frame and the sliding limit frame; the sliding limit frame is driven to move by the electric lead screw device 3, and heald frames 4 of different sizes can be used; a cylinder is fixedly installed at the bottom of the fixed limit frame; the heald frame 4 is driven by the cylinder to slide vertically up and down.

[0039] like Figure 4 As shown, a plurality of reed blocks 6 are vertically elastically slidably mounted on the heald frame 4; as a specific implementation of this embodiment, a plurality of vertical limiting slide grooves are provided on the heald frame 4; a reed block 6 is vertically elastically slidably mounted in the limiting slide groove; as a specific implementation of this embodiment, the bottom end of the reed block 6 is elastically connected to the heald frame 4 through a spring;

[0040] like Figure 6 As shown, the reed block 6 is provided with a special-shaped reed hole; the special-shaped reed hole is elliptical; the outer side of the special-shaped reed hole is rounded to prevent the warp yarn from being cut by the sharp corner; the semi-major axis and the semi-minor axis of the elliptical special-shaped reed hole have a specific proportional relationship, and the semi-major axis is in a vertical state. As a specific implementation of this embodiment, the ratio of the semi-major axis to the semi-minor axis of the special-shaped reed hole is 2.5:1; when the ratio of the semi-major axis to the semi-minor axis of the special-shaped reed hole is 2.5:1, the warp yarn is least likely to deflect during the weaving process. The reed block 6 is elastically connected to the heald frame 4, and when the heald frame 4 drives the warp yarn to move upward, it can effectively prevent the warp yarn from being broken due to excessive tension.

[0041] Specifically, Figure 1-2 As shown, the reed mechanism 5 includes: a mechanical arm 501 and a hook 502; the mechanical arm 501 is fixedly mounted on the mounting frame 1; the hook 502 is fixed at the front end of the mechanical arm 501; the hook 502 and the warp clamping mechanism 2 are respectively located at the front and rear sides of the heald frame 4. As a specific implementation of this embodiment, a serrated structure is added to the front end of the hook 502 to increase the friction between the hook 502 and the warp, effectively preventing the warp from falling off the hook 502.

[0042] Specifically, the reed mechanism 5 also includes: a detection mechanism 503; the detection mechanism 503 includes a laser sensor and a camera; the laser sensor is used to detect whether the hook hook 502 is aligned with the special-shaped reed hole; the camera is used to detect whether the color of the warp yarn hooked by the hook hook 502 is correct, and whether the warp yarn is broken; the detection mechanism 503 is fixedly installed on the mechanical arm 501; when the color of the warp yarn hooked by the hook hook 502 is incorrect or the warp yarn is broken, the control device controls the equipment to stop running.

[0043] The warp yarn clamping mechanism 2 clamps the warp yarn, and the warp yarn position adjustment mechanism 3 drives the warp yarn to move to the position corresponding to the special-shaped reed hole; at this time, the warp yarn between the upper clamping body and the lower clamping body on the wire clamp 201 corresponds to the special-shaped reed hole; the mechanical arm 501 drives the hook needle 502 to pass through the special-shaped reed hole to hook the warp yarn, the wire clamp 201 releases the warp yarn, and then the hook needle 502 resets, driving the warp yarn to pass through the special-shaped reed hole, completing the warp yarn threading process.

[0044] The reeding machine is heavy, and the reeding machines currently on the market are not easy to move, which is extremely inconvenient when changing the factory area or work position. Therefore, as a specific implementation of this embodiment, a universal wheel (not shown in the figure) is fixedly installed at the bottom of the mounting frame 1, and a locking device is provided on the universal wheel; when changing the work position, the mounting frame 1 is pushed to move to the specified position, and then the locking device locks the universal wheel.

[0045] The wire clamp 201, the electric screw device 1 302, the electric screw device 2 304, the mechanical arm, the electric screw device 3, the cylinder, the laser sensor and the camera are all electrically connected to the control device.

[0046] When the ratio of the semi-major axis to the semi-minor axis of the special-shaped reed hole is 2.5:1, the warp yarn is least likely to deflect during the weaving process; as a specific implementation of this embodiment, the following detection method is now provided:

[0047] Position deflection detection: The cylinder drives the heald frame 4 to move upward. After moving to the specified position, the robot arm 501 drives the camera to aim at the warp yarns passing through the special-shaped reed holes in turn, and the computer analyzes the deflection rate of the warp yarns.

[0048] Experimental methods

[0049] 1. Take 5 groups of heald frames 4; each group of heald frames 4 has different ratios of the semi-major axis and the semi-minor axis only in the special-shaped reed holes; the ratios of the semi-major axis and the semi-minor axis are 1:1, 2:1, 2.5:1, 3:1, and 4:1 respectively;

[0050] 2. Take warp yarns of the same material and pass them through the special-shaped reed holes on 5 groups of heald frames 4 respectively;

[0051] 3. The cylinder drives the heald frame 4 to move upward, and then the mechanical arm 501 drives the camera to observe the warp yarn, and the computer analyzes the deflection rate of the warp yarn.

[0052] Proportion 1:1 2:1 2.5:1 3:1 4:1 Deflection rate % 45 26 10 22 38

[0053] By observing the warp yarns on 5 groups of heald frames 4, it can be concluded that when the ratio of the major semi-axis to the minor semi-axis of the special-shaped reed hole is 2.5:1, the deflection rate of the warp yarn is the lowest; when the ratio of the semi-major axis to the semi-minor axis is too large, the position where the bottom of the special-shaped reed hole contacts the warp yarn is relatively gentle, and the warp yarn is easy to deflect during movement; when the ratio of the semi-major axis to the semi-minor axis is too small, the warp yarn is easy to contact the side of the special-shaped reed hole, resulting in the deflection of the warp yarn during movement; therefore, the best ratio of the semi-major axis to the semi-minor axis of the special-shaped reed hole is 2.5:1, and the number of warp yarn deflections is the least.

[0054] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
