Description

Technical Field

[0036] One end of the optical axis 5 is fixedly connected to each of the four corners of the lifting plate 4, and the optical axis 5 is slidably connected to the linear bearing on the fixed frame 2;

[0037] The other end of the optical axis 5 is fixedly connected to a bearing seat 6, and the two bearing seats 6 are rotatably connected to ultrasonic rollers 7;

[0038] The top of the lifting plate 4 is slidably connected to the support base 8, and the support base 8 is rotatably installed with a sprocket 1 9. The central axis of the ultrasonic roller 7 is fixedly connected to the sprocket 2 10. The sprocket 1 9 and the sprocket 2 10 are covered with a chain 11;

[0039] The fixing frame 2 is fixedly connected to the motor 12, the output shaft of the motor 12 is rotatably connected to one end of the telescopic rod 1, the other end of the telescopic rod 1 is rotatably connected to the intermediate shaft 13, the intermediate shaft 13 is rotatably connected to one end of the telescopic rod 2, and the other end of the telescopic rod 2 is rotatably connected to the central axis of the sprocket 1 9;

[0040] The output shaft of the motor 12 is connected to the intermediate shaft 13, and the intermediate shaft 13 is connected to the middle shaft of the sprocket 9. The telescopic rod 1 and the telescopic rod 2 form a V shape.

[0041] In this embodiment, by controlling the extension and retraction of the piston rod of the cylinder 3, the lifting and lowering of the lifting plate 4, the optical axis 5 and the ultrasonic roller 7 can be controlled. During lifting and lowering, in order to adapt to the height change of the central axis of the sprocket 1 9, the angle formed by the telescopic rod 1 and the telescopic rod 2 changes, but the distance between the intermediate shaft 13 and the central axis of the sprocket 1 9 and the output shaft of the motor 12 does not change, and the intermediate shaft 13 is rotatably connected to one end of the telescopic rod 2, and the other end of the telescopic rod 2 is rotatably connected to the central axis of the sprocket 1 9, so the rotation of the motor 12 can drive the ultrasonic roller 7 to rotate and will not be affected by the height.

[0042] Furthermore, the telescopic rod 1 includes a fixed rod 14 rotatably connected to the output shaft of the motor 12, the fixed rod 14 is slidably connected to two fixed shafts 15, the fixed shaft 15 is fixedly connected to the adjusting rod 16, and the adjusting rod 16 is rotatably connected to the intermediate shaft 13;

[0044] The swing arm 18 is threadedly connected with a screw 21, and the fixing rod 14 defines a groove for the screw 21 to be threadedly connected;

[0045] In this embodiment, if Figure 5 As shown, when the output shaft of the motor 12 and the intermediate shaft 13 maintain normal transmission, the screw 21 is screwed into the groove 1. When the distance between the intermediate shaft 13 and the output shaft of the motor 12 needs to be adjusted, the screw 21 is unscrewed, and then the swing arm 18 is rotated to change the distance between the adjusting rod 16 and the fixed rod 14.

[0046] Furthermore, the telescopic rod 2 includes a fixed rod 2 rotatably connected to the intermediate shaft 13 of the sprocket 1 9, the fixed rod 2 is slidably connected to the two fixed shafts 2, the fixed shaft 2 is fixedly connected to the adjusting rod 2, and the adjusting rod 2 is rotatably connected to the intermediate shaft 13;

[0047] The second fixing rod is rotatably connected to the two ends of the second swing arm through the second pin shaft, and the other two ends of the second swing arm are fixed with the second guide shaft. The second adjusting rod is fixedly connected to the second long strip plate with the second long strip hole, and the second guide shaft extends into the second long strip plate.

[0048] The second swing arm is threadedly connected with a second screw, and the second fixing rod is provided with a second groove for the second screw to be threadedly connected;

[0049] In this embodiment, if Figure 5 As shown, when the central axis of sprocket 19 and intermediate shaft 13 maintain normal transmission, screw 2 is screwed into groove 2. When the distance between the central axis of sprocket 19 and intermediate shaft 13 needs to be adjusted, screw 2 is unscrewed, and then swing arm 2 is rotated to change the distance between adjusting rod 2 and fixed rod 2.

[0050] Furthermore, the fixing rod 14 is fixedly connected with a stopper 22;

[0051] In this embodiment, if Figure 5 As shown, when the stopper 22 contacts the swing arm 18, the screw 21 faces the groove 1. At this time, the output shaft of the motor 12 and the intermediate shaft 13 maintain normal transmission, making the operation more convenient.

[0052] Furthermore, the second fixing rod is fixedly connected with a second stopper;

[0053] In this embodiment, if Figure 5 As shown, when the stopper 2 contacts the swing arm 2, the screw 2 faces the groove 2. At this time, the center axis of the sprocket 1 9 and the intermediate shaft 13 maintain normal transmission, making the operation more convenient.

[0054] Furthermore, the output shaft of the motor 12 and the intermediate shaft 13 are both fixedly connected to the sprocket three 23, and the two sprocket three 23 are fitted with the chain two 24;

[0056] In this embodiment, the chain three 26 and the chain two 24 drive the roller to rotate after the motor 12 is energized.

[0057] Furthermore, a screw module 27 is installed on the top of the lifting plate 4, and the output end of the screw module 27 is a driving block 28;

[0058] The support base 8 defines a through hole 29, which includes an inclined section and straight sections 1 and 2 connected to both ends of the inclined section. The driving block 28 is fixedly connected to the power shaft 30, which extends into the through hole 29.

[0059] In this embodiment, the screw module 27 is set up, so that the driving block 28 and the power shaft 30 can be translated. There is an angle between the inclined section and the moving trajectory of the power shaft 30. The straight line segment 1 coincides with the moving trajectory of the power shaft 30. The straight line segment 2 is parallel to the moving trajectory of the power shaft 30. When the power shaft 30 passes through the straight line segment 1 and the straight line segment 2, it will not affect the position of the support seat 8. When the power shaft 30 passes through the inclined section, the support seat 8 can be raised and lowered, thereby adjusting the tightness of the chain 11.

[0060] Furthermore, the outer ends of the groove 1 and the groove 2 are both flared;

[0061] In this embodiment, it is more convenient for the screw to enter the groove.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
