DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: a left-right movable box for an open heald frame, comprising an output box 1, an intermediate box 2 and an input box 3. The left and right sides of the intermediate box 2 are fixedly connected to the output box 1 and the input box 3 respectively by a plurality of bolts. The front side of the intermediate box 2 and the rear side of the input box 3 are respectively rotatably penetrated by a first rotating tube 8 and a second rotating tube 9. A left-right movable assembly is installed inside the output box 1, a reciprocating assembly is installed inside the intermediate box 2, an input assembly is installed inside the input box 3, and a distance adjustment assembly is installed between the input assembly and the reciprocating assembly.

[0023] The left-right moving box is assembled by an output box 1, an intermediate box 2 and an input box 3 fixed by several bolts. Power is input through the input component, and the reciprocating motion component and the left-right moving component realize the left-right movement of the open heald frame. A distance adjustment component is installed between the input component and the reciprocating motion component to adjust the left-right movement distance of the open heald frame.

[0024] The distance adjustment assembly includes a rotating disk 31, which is fixedly connected to the rear side of the first rotating tube 8. The rear side of the rotating disk 31 is fixedly connected to a sliding frame 10. A screw 12 is rotatably installed on the sliding frame 10. One end of the screw 12 close to the center of the rotating disk 31 is fixedly connected to a bevel gear three 22. A sliding block 11 is threadedly sleeved on the screw 12, and the sliding block 11 is slidably connected to the inner wall of the sliding frame 10. A rotating shaft 34 is rotatably installed inside the first rotating tube 8. The rear end of the rotating shaft 34 passes through the rotating disk 31 and is fixedly connected to a bevel gear four 23. The bevel gear four 23 is meshed with the bevel gear three 22. The front end of the rotating shaft 34 is fixedly connected to a disc gear seat two 33, and an adjustment mechanism is installed on the output box 1.

[0025] The adjusting mechanism includes an adjusting cylinder 27, which is rotatably installed on the front side of the input box 3. The front end of the adjusting cylinder 27 is fixedly connected to the knob 25. The inner wall of the adjusting cylinder 27 is slidably connected to the square rod 30. The front end of the square rod 30 is fixedly connected to the pressure rod 28. The front end of the pressure rod 28 passes through the knob 25 and extends out.

The rear end of the square rod 30 is fixedly connected to the disc tooth seat 1 32, and the disc tooth seat 1 32 is engaged with the disc tooth seat 2 33.

[0026] Pressing the pressure rod 28 causes the disc tooth seat 1 32 at the rear end of the square rod 30 to engage with the disc tooth seat 2 33 at the front end of the rotating shaft 34. Then, turning the knob 25 drives the adjusting cylinder 27 and the square rod 30 to rotate, thereby driving the rotating shaft 34 to rotate, so that the bevel gear 4 23 at the rear end of the rotating shaft 34, through the meshing action with the bevel gear 3 22, drives the screw 12 to rotate on the sliding frame 10, thereby realizing the sliding block 11 sliding on the sliding frame 10.

[0027] The left and right moving assembly includes a left and right moving rod 4, on which a rack 17 is fixedly sleeved, and the rack 17 is slidably installed on the inner bottom side of the output box 1.

[0028] Power is input through the first rotating rod 6 to rotate gear 15. Since gear 15 is engaged with gear 2 16, the third rotating rod 14 is rotated, thereby driving rack 17 to slide back and forth, thereby realizing the reciprocating sliding of the left and right moving rods 4.

[0029] The reciprocating motion component includes a rack 21, which is slidably installed on the inner bottom side of the intermediate box 2. The right end of the rack 21 is rotatably connected to the connecting rod 13, and the right end of the connecting rod 13 is rotatably connected to the sliding block 11. The fourth rotating rod 35 is rotatably installed inside the intermediate box 2. The left side of the intermediate box 2 is rotatably penetrated by a second rotating rod 7, and the right end of the second rotating rod 7 is fixedly connected to a bevel gear 18. The front and rear ends of the fourth rotating rod 35 are respectively fixedly connected to a bevel gear 2 19 and a gear 3 20. The bevel gear 2 19 is meshed with the bevel gear 18, and the gear 3 20 is meshed with the rack 2 21.

[0030] Power is input through the first rotating tube 8 to rotate the rotating disk 31, driving the sliding block 11 to rotate in a circle on the rotating disk 31. Since the sliding block 11 is rotationally connected to the connecting rod 13, the connecting rod 13 is rotationally connected to the rack 2 21, driving the rack 2 21 to reciprocate, and then rotating the gear 3 20 to rotate reciprocally. Through the reciprocating rotation of the fourth rotating rod 35 and the left and right meshing of the bevel gear 2 19 and the bevel gear 1 18, the second rotating rod 7 is driven to rotate reciprocally, and finally the first rotating rod 6 is driven to rotate reciprocally.

[0031] The input assembly includes an input shaft 5, which is rotatably arranged on the right side of the input box 3. The left end of the input shaft 5 is fixedly connected to a bevel gear 5 24. A bevel gear 6 26 is fixedly sleeved on the second rotating tube 9, and the bevel gear 6 26 is engaged with the bevel gear 5 24.

[0032] The external driving source rotates the input shaft 5 , which meshes with the bevel gear 5 24 via the bevel gear 6 26 , thereby rotating the second rotating tube 9 and further rotating the first rotating tube 8 .

[0033] The rear end of the second rotating tube 9 is key-connected to the front end of the first rotating tube 8, and the left end of the second rotating rod 7 is key-connected to the right end of the first rotating rod 6. Therefore, power can be transmitted after the rear end of the second rotating tube 9 and the first rotating tube 8 and the left end of the second rotating rod 7 and the right end of the first rotating rod 6 are plugged in.

[0034] Working principle: The left and right moving box is assembled by the output box 1, the intermediate box 2 and the input box 3 by a number of bolts. The input shaft 5 is rotated by an external driving source, and the bevel gear 6 26 is engaged with the bevel gear 5 24 to rotate the second rotating tube 9. Since the rear end of the second rotating tube 9 is key-connected with the front end of the first rotating tube 8, the first rotating tube 8 is rotated, and then the rotating disk 31 is rotated, driving the sliding block 11 to rotate on the rotating disk 31. Since the sliding block 11 is rotatably connected to the connecting rod 13, the connecting rod 13 is rotatably connected to the rack 2 21, driving the rack 2 The second rotating rod 7 is driven to rotate back and forth through the reciprocating rotation of the fourth rotating rod 35 and the left and right engagement of the bevel gear 2 19 and the bevel gear 1 18. Since the left end of the second rotating rod 7 is keyed to the right end of the first rotating rod 6, the first rotating rod 6 is driven to rotate back and forth, causing the gear 15 to rotate. Since the gear 15 is engaged with the gear 2 16, the third rotating rod 14 is rotated, driving the rack 17 to slide back and forth, thereby causing the left and right moving rods 4 to slide back and forth, thereby realizing the left and right movement of the open heald frame.

[0035] When the left and right moving distance of the left and right moving rod 4 needs to be adjusted, the pressure rod 28 is pressed so that the disc tooth seat 1 32 at the rear end of the square rod 30 engages with the disc tooth seat 2 33 at the front end of the rotating shaft 34, and then the knob 25 is turned to drive the adjusting cylinder 27 and the square rod 30 to rotate, thereby driving the rotating shaft 34 to rotate, so that the bevel gear 4 23 at the rear end of the rotating shaft 34 engages with the bevel gear 3 22, and drives the screw 12 to rotate on the sliding frame 10, so that the sliding block 11 slides on the sliding frame 10, thereby realizing the adjustment of the left and right moving distance of the open heald frame.
