Description

Technical Field

[0001] The present application relates to the technical field of production of all-cotton leno yarn-dyed fabrics, and in particular to a cotton yarn strip cutting device for all-cotton leno yarn-dyed fabrics. Background Art

[0002] Pure cotton gauze yarn-dyed fabric is a fabric made of pure cotton material with a unique gauze structure. The characteristic of pure cotton gauze yarn-dyed fabric lies in its gauze structure. This structure makes the surface of the fabric present clear and evenly distributed yarn holes, with a small warp and weft density, a light texture, a stable structure and good air permeability.

[0003] Cutting cotton yarn strips is an important step in the production process of all-cotton gauze yarn-dyed fabrics. A Chinese patent (Announcement No.: CN219709914U) discloses a cotton yarn cutting device for cotton yarn processing, which can press the cotton yarn to prevent burrs from forming at the cut end due to unevenness of the cotton yarn. However, the above document does not facilitate adjusting the position of the cutting knife according to the cutting length of the cotton yarn strips, resulting in the cutting length of the cotton yarn strips being adjusted according to processing requirements, which in turn makes the cutting device have certain limitations. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a cotton yarn strip cutting device for all-cotton gauze color-woven fabrics, which has the advantages of easy adjustment and solves the problem of inconvenient adjustment.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a cotton yarn cutting device for all-cotton leno yarn-dyed fabrics, comprising a cutting table, wherein narrow plates are fixed to the front and rear ends of the top of the cutting table, three brackets are provided at the top of the cutting table, the inner sides of the left and right brackets are provided with a pressing structure, a cutting knife is provided on the inner side of the middle bracket, a hydraulic rod is fixed to the top of the cutting knife, and adjustment components are provided at the front and rear ends of the middle bracket;

[0006] The adjustment assembly includes a measuring table, a pointing block, two T-shaped blocks, two groups of clamping blocks, push rods fixedly installed on the opposite ends of the two groups of clamping blocks, and a pushing structure fixedly installed on the opposite ends of the two groups of push rods.

[0007] By adopting the above technical solution, the distance between it and the left and right brackets can be adjusted according to the cutting length of the cotton yarn, so that it can be adjusted according to the required cotton yarn length, thereby ensuring the accuracy of the cut cotton yarn length.

[0008] Furthermore, the measuring meter is fixed to the top of the front narrow plate, the pointing block is slidably connected to the top of the front narrow plate, and the pointing block is fixed to the front side wall of the middle bracket.

[0009] The above technical solution is used to clearly know the distance data between it and the left and right brackets.

[0010] Furthermore, a sliding slot hole for allowing a T-shaped block to pass through the interior is opened on one side opposite to the other of the two narrow plates, and the two T-shaped blocks are respectively fixed to the front and rear walls of the middle bracket.

[0011] By adopting the above technical solution, the middle bracket can drive the two T-shaped blocks to move within the two narrow plates when the middle bracket moves.

[0012] Furthermore, the pushing structure includes two pressure plates, two groups of push blocks, two springs fixedly installed on opposite sides of the two pressure plates, and a connecting plate fixedly installed on the opposite ends of the two groups of push blocks. The top end of the connecting plate is rotatably connected to a screw through a bearing.

[0013] The above technical solution is adopted to push the two groups of clamping blocks to move relative to or away from each other, so as to clamp and fix the middle bracket.

[0014] Furthermore, the opposite walls of the two T-shaped blocks are each provided with a through hole for the clamping block to pass through, and the opposite walls of the two pressure plates are each provided with a connecting hole for the two push rods in the same group to pass through.

[0015] By adopting the above technical solution, the clamping block can be moved out of the T-shaped block, so that the front and rear groups of clamping blocks can contact the wall opposite to the front and rear groups of narrow plates, so that the middle bracket can be clamped and fixed, so that the pressure plate can be connected to the push rod, so that when the push rod moves, the push rod can also drive the pressure plate to move, so that the pressure plate can squeeze the spring.

[0016] Furthermore, the top ends of the two T-shaped blocks are provided with threaded holes for threaded connection of the screw rods therewith.

[0017] The above technical solution is adopted so that the screw can move in or out of the T-shaped block, thereby driving the two push blocks in the same group to move through the connecting plate, so that the push blocks can abut against the push rods, so that the two groups of push blocks can push the two groups of push rods to move relative to each other, and thus the two groups of push rods can drive the two groups of clamping blocks to move relative to each other.

[0018] Furthermore, the pressing structure includes a pressing roller, a support frame, a motor, two pressing rods hingedly mounted on the top of the support frame, a shift block fixedly mounted on the other end of the pressing rod, and a double-axis screw fixedly mounted on the output end of the motor.

[0019] By adopting the above technical solution, the two ends of the cotton yarn can be pressed and fixed, thereby reducing the burrs on the cut ends caused by the unevenness of the cotton yarn.

[0020] Furthermore, a movable hole for allowing the dual-axis screw rod to pass through the interior is opened on the opposite side of the front and rear shift blocks, and a long hole for allowing the two pressing rods to pass through the interior is opened at the lower end of the bracket.

[0021] The above technical solution is adopted so that the double-axis screw rod can be threadedly connected to the moving block through the moving hole, thereby driving the front and rear moving blocks to move relative to or away from each other; and the pressing rod can pass through the interior of the bracket 3 through the long hole, so that the pressing rod can be connected to the support frame, so that the pressing rod can pull or push the pressure roller up or down through the support frame.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The cotton yarn strip cutting device for all-cotton gauze yarn-dyed fabric is provided with an adjustment component, which can adjust the position of the cutting knife on the cutting table, so as to adjust the distance between the cutting knife and the left and right brackets according to the cutting length of the cotton yarn, thereby being able to adjust according to the required cotton yarn length, thereby ensuring the accuracy of the cut cotton yarn length, and by providing a pressing structure, it can reduce the burr phenomenon at the cut end caused by uneven cotton yarn.

[0044] It should be noted that the infrared sensor 4 and the electronic components appearing in the text are all commonly known to the public in the prior art. The control method of this embodiment is controlled by a controller. The electrical components appearing in the text are all connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also well known in the art, so the control method and circuit connection are no longer explained in detail in this utility model.

[0045] The working principle of the above embodiment is:

[0046] When in use, the two screw rods 610 are rotated so that the screw rods 610 drive the two push blocks 68 of the same group to move upward through the connecting plate 69, so that the push blocks 68 no longer abut against the push rods 65, and the springs 67 are no longer squeezed by the pressure. The two sets of springs 67 push the two pressure plates 66 to move away from each other, so that the two pressure plates 66 drive the two sets of clamping blocks 64 to move away from each other through the two sets of push rods 65, so that the two sets of clamping blocks 64 can move into the T-shaped block 63, thereby enabling the middle bracket 3 to drive the cutting knife 6 to move freely on the cutting table 1, so that the distance between it and the left and right brackets 3 can be adjusted according to the cutting length;

[0047] After the adjustment is completed, the screw rod 610 is rotated so that the screw rod 610 drives the push block 68 to move downward through the connecting plate 69, so that the two sets of push blocks 68 can push the two pressure plates 66 to move relative to each other through the two sets of push rods 65, so that the pressure plates 66 can press the springs 67, and the two sets of push rods 65 can drive the two sets of clamping blocks 64 to move relative to each other, so that the two sets of clamping blocks 64 can move out of the T-shaped block 63 and abut against the wall opposite to the two narrow plates 2, so that the middle bracket 3 can be clamped and fixed to the top of the cutting table 1;

[0048] The output end of the motor 36 drives the double-axis screw 35 to rotate, so that the double-axis screw 35 drives the front and rear moving blocks 34 to move relative to each other. The two moving blocks 34 push the support frame 32 downward through the two pressing rods 33, so that the pressing roller 31 can press the cotton yarn, which can reduce the burrs on the cut end caused by the unevenness of the cotton yarn.

[0049] The cotton yarn moves to the pressing structure of the right bracket 3, so that the right pressing structure presses and fixes the cotton yarn. When the cut end of the cotton yarn moves to the lower end of the infrared sensor 4, the control end controls the left pressing structure to work, and repeats the above steps so that the left pressing structure can press and fix the cut end of the cotton yarn, and the cutting knife 6 in the normal position can be adjusted to cut the cotton yarn so that it can be adjusted according to the required cotton yarn length.
