Description

Technical Field

[0001] The utility model relates to the technical field of belt adjustment, in particular to a tensioning mechanism for a belt tensioner. Background Art

[0002] Belt tensioning is a common concept in mechanical transmission, especially in belt drive systems. It mainly refers to ensuring that the belt maintains proper tightness during transmission by adjusting or increasing the tension to achieve effective power transmission.

[0003] During long-term use, dust will accumulate on the surface of the belt, which will reduce the friction of the belt. The friction of the belt drive is very important. In belt drive, friction is one of the key factors in transmitting power. Although the current tensioning mechanism can effectively tighten the belt and increase friction, its function is relatively single and cannot further increase the friction of the belt.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The tensioning mechanism for a belt tensioner provided by the utility model comprises: a base plate 1, and also comprises: a vertical plate 3 installed on the top outer wall of the base plate 1, a top moving assembly 2 is screwed on the outer wall of one side of the vertical plate 3, and a sliding opening 4 is opened on the outer wall of one side of the vertical plate 3, a sliding block 5 is slidably connected to the inner wall of the sliding opening 4, and a support frame 6 is installed on the outer wall of one side of the sliding block 5, a top roller 7 is rotatably installed on the outer wall of one side of the support frame 6, and a fixing frame 8 is installed on the top outer wall of the support frame 6, through holes are opened at both ends of the top outer wall of the fixing frame 8, and elastic rods 9 are inserted in the two through holes, the bottoms of the two elastic rods 9 are connected to the same T-plate 10, and a dust removal assembly 11 is rotatably installed on the outer wall of one side of the T-plate 10, a dust suction assembly 12 is installed on the fixing frame 8, and one end of the dust suction assembly 12 is rotatably connected to one end of the dust removal assembly 11.

[0022] It should be noted here that: the position of the top moving component 2 can be adjusted to adjust the height of the support frame 6, and then the height of the top roller 7 can be adjusted, so that the top roller 7 pushes the belt 14 upward to tighten the belt for better transmission. After the belt 14 is lifted up, it will contact the surface of the dust removal component 11 during the rotation process. The two elastic rods 9 can lightly press the dust removal component 11 on the belt 14. The belt 14 can drive the dust removal component 11 to rotate during the rotation process. The dust removal component 11 is used to remove dust from the side of the belt 14 that is in contact with the transmission wheel 13, and the dust suction component 12 is used to suck away the raised dust. While the belt is tensioned, the dust on the side of the belt 14 that is in contact with the transmission wheel 13 is also removed, thereby further increasing the friction between the belt 14 and the transmission wheel 13, and further improving the transmission effect.

[0023] In a preferred embodiment, the lifting assembly 2 includes a threaded rod 201 , a lifting frame 202 rotatably mounted on one end of the threaded rod 201 , and a rotating rod 203 fixed to the other end of the threaded rod 201 .

[0024] It should be noted here that: the rotatable threaded rod 201 pushes the moving frame 202 to move, and the moving frame 202 is pressed against the bottom of the supporting frame 6. The movement of the moving frame 202 can drive the supporting frame 6 to move up and down.

[0025] In a preferred embodiment, the elastic rod 9 includes a movable rod 901 and a spring 902 sleeved on the outer wall of the movable rod 901 .

[0026] It should be noted here that after the belt 14 is lifted up, it contacts the dust removal assembly 11, pushes the dust removal assembly 11 and the T-plate 10 upward, squeezes the spring 902, and the dust removal assembly 11 is lightly pressed onto the belt 14 through the reaction force of the spring 902.

[0027] In a preferred embodiment, the dust removal assembly 11 includes a hollow roller 1101 , a plurality of equally spaced dust suction holes 1102 opened on the outer wall of the hollow roller 1101 , and a plurality of equally spaced wiping blocks 1103 fixed on the outer wall of the hollow roller 1101 .

[0028] It should be noted here that: the belt 14 is in contact with the outer wall of the wiping block 1103, and the rotation of the belt 14 drives the hollow roller 1101 to rotate, and then drives the wiping block 1103 to rotate, and the dust on the surface of the belt 14 is wiped off by the wiping block 1103, and the dust is sucked away through the dust suction hole 1102 by using the dust suction component 12 to draw air.

[0029] In a preferred embodiment, the dust collection assembly 12 includes an exhaust pipe 1201 and an electric fan 1202 installed on the inner wall of the exhaust pipe 1201, and a dustproof shell is installed on the outside of the motor of the electric fan 1202, and a flexible connecting pipe 1203 is connected to the exhaust pipe 1201.

[0030] It should be noted here that the electric fan 1202 can exhaust air so that the dust is sucked into the hollow roller 1101 through the dust suction hole 1102, and then enters the exhaust pipe 1201 to be blown away. Since the position of the exhaust pipe 1201 is fixed and the position of the hollow roller 1101 is movable, a flexible connecting pipe 1203 is connected to one end of the exhaust pipe 1201, so that the exhaust pipe 1201 can be easily connected to the hollow roller 1101.

[0031] In a preferred embodiment, the outer wall of one end of the exhaust pipe 1201 close to the flexible connecting pipe 1203 is connected to the inner wall of one end of the hollow roller 1101 through a bearing.

[0032] It should be noted here that the rotation of the hollow roller 1101 does not affect the exhaust pipe 1201 .

[0033] Working principle: The rotatable threaded rod 201 pushes the moving frame 202 to move, and the moving frame 202 is pressed against the bottom of the support frame 6. The movement of the moving frame 202 can drive the support frame 6 to rise and fall, and adjust the height of the support frame 6, and then adjust the height of the top roller 7, so that the top roller 7 pushes the belt 14 upward, so that the belt is tightened and the transmission is better. After the belt 14 is lifted up, it will contact the outer wall of the wiping block 1103 during the rotation process, and push the hollow roller 1101 and the T-plate 10 upward, squeezing the spring 902, and the hollow roller 1101 is lightly pressed on the belt 14 through the reaction force of the spring 902;

[0034] The rotation of the belt 14 drives the hollow roller 1101 to rotate, and then drives the wiping block 1103 to rotate. The dust on the surface of the belt 14 is wiped off by the wiping block 1103, and the electric fan 1202 can exhaust air so that the dust is sucked into the hollow roller 1101 through the dust suction hole 1102, and then enters the exhaust pipe 1201 to be blown away, and the dust is removed from the side of the belt 14 that contacts the transmission wheel 13. While the belt is tensioned, the dust on the side of the belt 14 that contacts the transmission wheel 13 is also removed, thereby further increasing the friction between the belt 14 and the transmission wheel 13 and further improving the transmission effect.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
