Description

Technical Field

[0001] This utility model belongs to the field of circular knitting machine technology, and in particular relates to a structure for adjusting the opening angle of the knitting machine's opening blade. Background Technology

[0002] The spreading knife (also known as "spreading knife" or "width expansion device") of a circular knitting machine is a key component, mainly used to spread the formed fabric laterally to both sides during the knitting process to ensure that the fabric reaches the predetermined width and flatness.

[0003] Most existing sprue cutters have a fixed angle when cutting the fabric, which means that the device needs to be disassembled and reinstalled when the blade angle is changed, resulting in reduced work efficiency. To address this, we provide a sprue cutter angle adjustment structure for circular knitting machines. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for adjusting the angle of the cutting blade of a circular knitting machine. The rotating teeth drive the rotating block to rotate, which in turn drives the protective cover to rotate. Then, the movement of the protective cover drives the cutting blade to move, thereby adjusting the angle of the cutting blade. This improves the adaptability of the device and solves the problem that existing devices need to be disassembled and reinstalled when changing the blade angle, which reduces work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

A first fixing tooth is fixedly connected to the inner wall of the rotating block, and a second fixing tooth is fixedly connected to the inner wall of the connecting block. A push rod is slidably connected to the inner wall of the connecting block, and a second knob is fixedly connected to the front of the push rod. Rotation of the second locking tooth drives the rotating block to rotate, thereby driving the protective cover to rotate. Then, the movement of the protective cover drives the cutting blade to move, thus adjusting the angle of the cutting blade and improving the adaptability of the device.

[0007] Furthermore, a second locking tooth is fixedly connected to the outer surface of the push rod. The second locking tooth is adapted to the inner wall of the first fixed tooth. A rotating plate is engaged with the back of the second locking tooth. A spring is fixedly connected to the back of the rotating plate. The back of the spring is fixedly connected to the inner wall of the rotating block. The first locking tooth is fixedly connected to the outer surface of the push rod. The spring rebounds to allow the second fixed tooth to re-enter the first locking tooth for limiting the movement.

[0008] Furthermore, the outer surface of the first tooth is adapted to the inner wall of the second fixed tooth, a protective cover is fixedly connected to the bottom of the rotating block, a motor is fixedly connected to the right side of the protective cover, and a cutting blade is fixedly connected to the left output end of the motor through a coupling. The cutting blade is set inside the protective cover and is used to cut the fabric.

[0009] Furthermore, the support mechanism and the placement box are provided. The inner wall of the placement box is fixedly connected to a support frame, the outer surface of the support frame is slidably connected to a moving block, the inner wall of the moving block is threadedly connected to a threaded rod, the top of the threaded rod is fixedly connected to a knob, and the bottom of the threaded rod is rotatably connected to a pressing block. The moving block moves the connecting block.

[0010] Furthermore, a limiting rod is fixedly connected to the top of the extrusion block, and the outer surface of the limiting rod is slidably connected to the inner wall of the moving block. The bottom of the extrusion block is in contact with the top of the support frame, and the bottom of the moving block is fixedly connected to the top of the connecting block. Pushing the moving block causes it to move the connecting block and the arc-shaped rod to a suitable position so that it can be used for different sizes of fabric.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model uses a cutting blade, specifically, the rotation of knob two drives the push rod to rotate, and then the rotation of the push rod drives the clasp two to rotate, and then the rotation of the clasp two drives the rotating block to rotate, thereby driving the protective cover to rotate. Then the movement of the protective cover drives the cutting blade to move, thereby adjusting the angle of the cutting blade and improving the adaptability of the device.

[0013] 2. This utility model uses a movable block, specifically, the rotation of a knob drives the threaded rod to rotate, and then the rotation of the threaded rod drives the extrusion block to move upward, so that it is disengaged from the support frame. Then, the movable block is pushed, which drives the connecting block and the arc-shaped rod to move to a suitable position so that it can be used for different sizes of fabric.

The rotation of the knob 203 drives the push rod 210 to rotate. Then, the rotation of the push rod 210 drives the locking tooth 207 to rotate. Then, the rotation of the locking tooth 207 drives the rotating block 202 to rotate, thereby driving the protective cover 213 to rotate. Then, the movement of the protective cover 213 drives the cutting knife 212 to move, thereby adjusting the angle of the cutting knife 212 and improving the adaptability of the device.

[0024] The outer surface of the push rod 210 is fixedly connected with a second locking tooth 207, which is adapted to the inner wall of the first fixed tooth 204. A rotating plate 208 is engaged with the back of the second locking tooth 207.

[0026] The outer surface of the first tooth 206 is adapted to the inner wall of the second fixed tooth 205. The bottom of the rotating block 202 is fixedly connected to the protective cover 213. The right side of the protective cover 213 is fixedly connected to the motor 211. The left output end of the motor 211 is fixedly connected to the cutting blade 212 through the coupling. The cutting blade 212 is set inside the protective cover 213.

[0027] The support mechanism 1 and the placement box 101 are provided. The inner wall of the placement box 101 is fixedly connected to the support frame 102. The outer surface of the support frame 102 is slidably connected to the moving block 103. The knob 104 is rotated to drive the threaded rod 105 to rotate. Then, the rotation of the threaded rod 105 drives the extrusion block 107 to move upward, so that it is disengaged from above the support frame 102. Then, the moving block 103 is pushed, so that it drives the connecting block 201 and the arc rod 108 to move to a suitable position to accommodate different sizes of fabric.

[0028] The inner wall of the movable block 103 is threaded with a threaded rod 105. A knob 104 is fixedly connected to the top of the threaded rod 105, and a pressing block 107 is rotatably connected to the bottom of the threaded rod 105.

[0030] A specific application of this embodiment is as follows: In use, the fabric is first placed in the placement box 101, then the knob 104 is turned. The rotation of the knob 104 drives the threaded rod 105 to rotate, and then the rotation of the threaded rod 105 drives the pressing block 107 to move upward, so that it is disengaged from above the support frame 102. Then the moving block 103 is pushed, so that it drives the connecting block 201 and the arc rod 108 to move to a suitable position to accommodate different sizes of fabric. Then the fabric is pulled out and placed on top of the support frame 102, so that one side of the fabric is between the cutting blade 212 and the arc rod 108. Then the knob 203 is pushed, and the movement of the knob 203 drives the push rod 210 to move backward. Then the movement of the push rod 210 drives the clamp. Tooth 206 and clamping tooth 207 move. When clamping tooth 207 moves, it compresses spring 209. Since the length of fixed tooth 204 is longer than that of fixed tooth 205, clamping tooth 206 will disengage from fixed tooth 205 when clamping tooth 207 compresses spring 209. Then, knob 203 is rotated. The rotation of knob 203 drives push rod 210 to rotate. Then, the rotation of push rod 210 drives clamping tooth 207 to rotate. Then, the rotation of clamping tooth 207 drives rotating block 202 to rotate, thereby driving protective cover 213 to rotate. Then, the movement of protective cover 213 drives cutting blade 212 to move, thereby adjusting the angle of cutting blade 212. Then, motor 211 is started to cut the fabric.
