Description

Technical Field

[0001] The utility model relates to the technical field of coarse sand conductors, in particular to a conductor mechanism for a coarse roving machine. Background Art

[0002] A roving frame is a type of textile machinery primarily used to process fibers such as cotton, linen, and wool into coarse yarn. The guide mechanism is a crucial component in the operation of the roving frame. Its primary function is to guide the roving smoothly from the bobbin, facilitating subsequent processing steps.

[0003] However, since the wire outlet position of the bobbin will change continuously during the rotation of the bobbin, and the wire outlet orientation of each bobbin is also inconsistent when the bobbin is installed, the guide of some wire guiding mechanisms on the market is fixed, which often causes damage to the yarn during guiding. This will cause the wire guiding mechanism to become unstable when guiding the coarse yarn, thereby affecting the quality of the coarse yarn. Utility Model Content

[0004] In view of this, the utility model provides a wire guide mechanism for a roving machine, which can enable the wire guide frame to adjust its position accordingly, thereby maintaining the stability of the wire guide process.

[0005] In order to solve the above technical problems, the utility model provides a wire guide mechanism for a roving machine, including a bracket, the center of the bracket is rotatably connected to a wire bobbin, one side of the bracket is rotatably connected to two bidirectional screws symmetrically distributed up and down, and two wire guide racks symmetrically distributed along the axial direction of the bidirectional screws are threadedly connected between the two bidirectional screws, so that the wire guide rack can adjust its position accordingly to ensure that the thread end always remains in the middle of the wire guide rack, thereby maintaining the stability of the wire guide process.

[0006] A slide groove is provided on the top of one side of the bracket, the middle part of the wire rack is slidably connected to the slide groove, and the top of the wire rack is fixedly connected to the limit plate; that is, the stable movement of the wire rack in the slide groove is guaranteed.

[0007] The shape of the wire racks is a hollow rectangle, and the inner side surfaces of the wire racks are all arc surfaces; that is, the friction between the yarn and the wire racks is reduced, and the wire efficiency is improved.

[0008] A sprocket is fixedly connected to the middle of one end of the bidirectional screw, and the two sprockets are connected through a chain transmission. A motor is fixedly connected to one side of the bracket, and the output shaft of the motor is fixedly connected to the middle of one end of the adjacent bidirectional screw; thus, precise adjustment of the position of the wire rack is achieved.

[0009] The upper and lower ends of the conductor rack are fixedly connected to buffer racks, and the frame bodies of the conductor rack located between the buffer racks are slidably connected to conductor rollers; that is, the stability and adaptability of the conductor during the conductor process are enhanced, and the conductor quality of the yarn is improved.

[0010] The middle parts of both ends of the buffer frame are fixedly connected with guide columns, and both ends of the wire roller are slidably connected to the middle parts of adjacent guide columns, so as to provide stable guidance for the wire roller.

[0011] The guide column is located between the side of the wire roller away from the middle of the bracket and the inner side of the adjacent buffer frame, and a buffer spring is sleeved on the middle of the column; that is, it provides a buffering effect to prevent the yarn from breaking due to being too high or too low.

[0012] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0013] 1. When the outlet position changes, the bidirectional screw can be rotated by starting the motor to adjust the position of the wire rack accordingly, ensuring that the wire head always remains in the middle of the wire rack, thereby maintaining the stability of the wire process.

[0014] 2. When the yarn is too high or too low, it will contact the guide roller. Under the action of the yarn, the guide roller will move along the guide column, and the buffer spring will be compressed to play a buffering role to prevent the yarn from breaking due to hard collision with the bracket due to the high or low position.

[0021] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4, clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown: this embodiment provides a wire guide mechanism for a roving machine, including a bracket 100, the center of the bracket 100 is rotatably connected to a wire bobbin 101, one side of the bracket 100 is rotatably connected to two bidirectional screws 102 distributed symmetrically above and below, and two wire guides 103 distributed symmetrically along the axial direction of the bidirectional screws 102 are threadedly connected. The wire guides 103 are all hollow rectangular in shape, and the inner side surfaces of the wire guides 103 are all arc surfaces, which are convex. A slide groove 104 is provided on the top of one side of the bracket 100, and the middle part of the wire guides 103 is slidably connected to the slide groove 104. The width of the limit plate is greater than the width of the slide groove 104, and the middle part of one end of the bidirectional screw 102 is fixedly connected to a sprocket 105, and the two sprockets 105 are transmission-connected by a chain 106. One side of the bracket 100 is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the middle part of one end of the adjacent bidirectional screw 102;

[0023] The two guide rails 103 are rotated to move the guide rails 103 in a direction that is symmetrical with respect to the axis of the guide rails 102.

[0024] When conducting wire, the yarn is constantly in contact with the arc surface of the working wire rack 103. The arc surface design effectively reduces the friction between the yarn and the wire rack 103, thereby improving the wire conducting efficiency of the yarn. The hollow design enables wire conducting on both sides of the wire rack 103, thereby effectively improving the adaptability when conducting wire. At the same time, due to the limitation of the slide groove 104, the wire rack 103 can only slide in the slide groove 104, thereby ensuring the stability and accuracy of the wire rack 103. The design of the limit plate limits the movement range of the wire rack 103 in the slide groove 104, thereby preventing excessive movement of the wire rack 103 and ensuring the smooth progress of the wire conducting process.

[0025] Buffer rack 107 Figure 2 、 3 As shown,

[0026] The upper and lower ends of the wire rack 103 are fixedly connected to the buffer rack 107. The frame of the wire rack 103 located between the buffer racks 107 is slidably connected to a wire roller 108. The diameter of the wire roller 108 is smaller in the middle and larger at both ends. The middle of both ends of the buffer rack 107 are fixedly connected to a guide column 109. Both ends of the wire roller 108 are slidably connected to the middle of the adjacent guide column 109. The guide column 109 is located between the side of the wire roller 108 away from the middle of the bracket 100 and the inner side of the adjacent buffer rack 107. The middle of the column is sleeved with a buffer spring.

[0027] When the position of the yarn is too high or too low, it will contact the wire roller 108. Under the action of the yarn, the wire roller 108 will move along the guide column 109, and the buffer spring will be compressed to play a buffering role to prevent the yarn from breaking due to a hard collision with the bracket 100 caused by a position that is too high or too low. At the same time, since the diameters of the two ends of the wire roller 108 are larger and the diameter in the middle is smaller, the yarn can always be kept in the middle of the wire roller 108 during the wiring process, ensuring the stability of the yarn.

[0028] Working principle:

[0029] First, place the bobbin in the middle of the bobbin 101, select the nearest wire rack 103 according to the position of the thread end, and place the thread end in the middle of the wire rack 103. After starting the motor, the sprocket 105 and chain 106 are used to control the synchronous rotation of the two bidirectional screws 102. The rotation of the bidirectional screw 102 adjusts the position of the two wire racks 103 so that the position of the working wire rack 103 can match the device in the next process. The yarn is constantly in contact with the arc surface of the working wire rack 103. The arc surface design effectively reduces the friction between the yarn and the wire rack 103, improves the yarn conducting efficiency, and the hollow design makes Both sides of the wire rack 103 can carry out wire routing, which effectively improves the adaptability of wire routing. Due to the limitation of the slide groove 104, the wire rack 103 can only slide in the slide groove 104. The design of the limit plate limits the movement range of the wire rack 103 in the slide groove 104, preventing excessive movement of the wire rack 103 and ensuring the smooth progress of the wire routing process. When the position of the yarn is too high or too low, it will contact the wire roller 108. Under the action of the yarn, the wire roller 108 will move along the guide column 109, and the buffer spring will be compressed to play a buffering role to prevent the yarn from breaking due to being too high or too low.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
