Description

Technical Field

[0001] This utility model relates to the field of steel reed processing technology, specifically a steel reed grinding machine. Background Technology

[0002] The reed is an important component in textile machinery. It is usually made of high carbon steel or stainless steel, which is wear-resistant and corrosion-resistant. It is mainly used to fix the position of the warp yarns and control the fabric density. It is made up of multiple thin steel strips arranged in parallel. The even distribution of the warp yarns is ensured by the precise spacing. The warp density of the fabric is determined by adjusting the reed number or the warp threading method. The reed grinding machine is a special equipment for processing reeds. It performs fine grinding on the surface of the reed to restore its smoothness.

[0003] Some existing reed grinding machines first fix the reed on the machine fixture when grinding the reed. Then, the position of the grinding head is adjusted by the electric slide rail. Then, the grinding head is driven by the motor to rotate at high speed to grind the reed. After grinding, the reed is removed from the fixture, flipped over, and fixed again for grinding.

[0004] Existing reed grinding machines of this type have the following problems: when grinding the reed, it is necessary to manually flip the reed over to grind the other side, which will waste a lot of time and greatly reduce the efficiency of reed grinding. Therefore, we propose a reed grinding machine. Utility Model Content

Adjusting blocks are fixedly connected to the upper ends of the T-support rods. Fixed claws are rotatably connected to the opposite inner sides of the adjusting blocks. When grinding the reed, the mechanism automatically flips the reed, reducing wasted time and improving the efficiency of reed grinding.

[0008] Furthermore, the machine tool is equipped with a controller on its exterior.

The input end of the second motor is electrically connected to the output end of the controller to provide a rotatable connection.

[0011] Furthermore, the drive assembly also includes a motor and a bidirectional lead screw. The bidirectional lead screw is rotatably connected to the middle of the left and right inner walls of the machine base. The left and right ends of the bidirectional lead screw are respectively threaded to the threaded holes at the middle of the lower end of the vertically adjacent T-support rod. The left end of the machine base is equipped with a motor. The right end of the output shaft of the motor is fixedly connected to the left end of the bidirectional lead screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This reed grinding machine has the following advantages:

[0016] Driven by motor one, the T-support rod slides along the guide rod via a two-way lead screw, which in turn drives the fixed claw to clamp or loosen steel reeds of different lengths via an adjusting block. Then, driven by motor two, the rotating column rotates through the meshing of the worm and worm wheel. The rotating column drives the fixed claw to rotate and flip the steel reed. When grinding the steel reed, the automatic flipping of the steel reed reduces the wasted time and improves the efficiency of steel reed grinding. Attached Figure Description

The bellows will be fitted over the threaded rod 10 to protect it, preventing debris from entering the threads of the threaded rod 10 and affecting its operation.) The transmission of the internal threaded cylinder 9 is fixedly connected to the upper end of the electric slide rail 4. The upper end of the machine base 1 is equipped with a motor 4 11. The lower end of the output shaft of the motor 4 11 is fixedly connected to the upper end of the threaded rod 10.

[0023] The flipping clamping mechanism 2 includes guide rods 21, T-support rods 22, adjusting blocks 23, and fixed claws 25. Guide rods 21, symmetrically arranged front and rear, are fixedly connected between the left and right inner walls of the machine base 1. T-support rods 22 are slidably connected to the left and right ends of the two guide rods 21, respectively.

The middle part of the counting shaft of the angle sensor 26 is fixedly connected to the right end of the rotating column 24. The angle sensor 26 is bidirectionally electrically connected to the controller 12. The flipping clamping mechanism 2 also includes a drive assembly 27, which includes a worm gear 273, a worm 274, and a second motor 275. The worm gear 273 is fixedly sleeved in the middle of the rotating column 24. The worm 274 is rotatably connected to the right wall of the circular cover 28. The worm gear 273 and the worm 274 are meshed together. The second motor 275 is provided at the right end of the circular cover 28. The left end of the output shaft of the second motor 275 is fixedly connected to the right end of the worm 274. The input end of the second motor 275 is electrically connected to the output end of the controller 12. (The worm gear 273 and the worm 274 are located inside the circular cover 28.) The drive assembly 27 also includes a motor 271 and a double-acting lead screw 272. The double-acting lead screw 272 is rotatably connected to the middle of the left and right inner walls of the machine base 1. (A second bellows is fixedly connected between the left wall of the machine base 1 and the left end of the left T-support rod 22, between the opposite ends of the two T-support rods 22, and between the right end of the right T-support rod 22 and the right wall of the machine base 1. The second bellows are respectively sleeved on the outside of the double-acting lead screw 272 to prevent debris from entering the threads of the double-acting lead screw 272 and affecting its transmission.) The left and right ends of the double-acting lead screw 272 are respectively connected to the vertically adjacent T-support rods. The threaded hole at the lower middle of the rod 22 is threaded. A motor 271 is located at the left end of the machine base 1. The right end of the output shaft of motor 271 is fixedly connected to the left end of the bidirectional lead screw 272. The input end of motor 271 is electrically connected to the output end of controller 12. When grinding the reed, motor 271 operates by controlling controller 12. The output shaft of motor 271 drives the bidirectional lead screw 272 to rotate. The bidirectional lead screw 272 is threadedly connected to the threaded holes at the lower ends of the two T-support rods 22 on the left and right sides. The T-support rods 22 slide along guide rod 21, thereby driving the fixed claw 25 to move synchronously through adjusting block 23, achieving clamping or loosening of reeds of different lengths. (Since the vertical inner wall distance between positioning plate 13 and the left fixed claw 25 is a fixed value, let's call it 'a'.)Since the distance between the probe of the laser positioner 14 and the vertical inner wall of the right-side fixed claw 25 is a fixed value, let's call it b, during the movement of the two fixed claws 25, the laser positioner 14 measures the distance between itself and the positioning plate 13 in real time and submits the detection data to the controller 12. For example, if the detection data is c, and you want to clamp a certain length of reed, such as d, then d = c - (a + b). Therefore, based on the length of the reed, you input the desired clamping length data into the controller 12 in advance. Then, based on the distance data between the laser positioner 14 and the positioning plate 13, and the calculation formula d = c - (a + b), the controller 12 can adjust the distance between the two 25s to d to properly clamp the d gauge. The system uses reeds of varying lengths to clamp them. When the reed needs to be flipped, the controller 12 activates motor 275. The output shaft of motor 275 drives worm gear 274, which in turn drives rotating column 24 via meshing worm wheel 273. The rotation of rotating column 24 causes the right-side fixing claw 25 to rotate, thus flipping the reed through the left-side fixing claw 25. Angle sensor 26, connected to rotating column 24 via a counting shaft, detects the rotation angle of rotating column 24 in real time and feeds the signal back to controller 12. The controller then stops motor 275 according to the set angle, achieving precise flipping of the reed.

[0024] The working principle of the reed grinding machine provided by this utility model is as follows: When grinding the reed, the controller 12 controls the operation of motor 271. The output shaft of motor 271 drives the bidirectional lead screw 272 to rotate. The bidirectional lead screw 272 is threadedly connected to the threaded holes at the lower ends of the left and right T-support rods 22, and the T-support rods 22 slide along the guide rod 21. Then, the adjusting block 23 drives the fixed claw 25 to move synchronously, realizing the clamping or loosening of reeds of different lengths. Next, the controller 12 controls the operation of electric slide rail 4. The sliding seat of electric slide rail 4 drives electric slide rail 5 to move left and right, realizing the left and right position adjustment of the grinding disc 8. The sliding seat of electric slide rail 5 drives L-shaped bracket 6 to move back and forth, realizing the front and back position adjustment of the grinding disc 8. The output shaft of motor 11 drives the threaded rod 10 to rotate. The reed is threadedly engaged with the internal threaded cylinder 9. The internal threaded cylinder 9 drives the electric slide rail 1 4 and the grinding assembly below to move up and down as a whole, thereby adjusting the height of the grinding disc 8. The output shaft of the motor 3 7 drives the grinding disc 8 to rotate at high speed to grind the reed. When it is necessary to flip the reed, the controller 12 controls the operation of the motor 275. The output shaft of the motor 275 drives the worm 274 to rotate. The worm 274 drives the rotating column 24 to rotate through the meshing worm wheel 273. The rotation of the rotating column 24 will drive the right fixed claw 25 to rotate, and then flip the reed through the left fixed claw 25. The angle sensor 26 is connected to the rotating column 24 through the counting shaft to detect the rotation angle of the rotating column 24 in real time and feed the signal back to the controller 12. The controller controls the motor 275 to stop according to the set angle, so as to achieve precise flipping of the reed.

[0025] It is worth noting that the electric slide rail 4, electric slide rail 5, motor 271, motor 275, motor 7, motor 4 11, and laser positioner 14 disclosed in the above embodiments are as follows: electric slide rail 4 can be E1000, electric slide rail 5 can be Micro2PLUS, motor 271 can be Z-355A, motor 275 can be NEMA8, motor 7 can be js114-4, motor 4 11 can be Z2-41, and laser positioner 14 can be yd-d650p100-a10.
