[0048] like Figures 1 to 4As shown, this embodiment provides a tension adjusting device for adjusting the tension of the belt 30 in a cutting mechanism. The cutting mechanism includes a cutting base 10, a driven wheel 11, a driving base 20, a driving wheel 21, and a driving member 22. The driven wheel 11 is rotatably mounted on the cutting base 10 via a rotating shaft. The driving wheel 21 is located at the output end of the driving member 22. The driving member 22 is fixedly mounted on the driving base 20, and the driving base 20 is slidably mounted on the cutting base 10, allowing the driving wheel 21 to move closer to or further away from the driven wheel 11. The belt 30 is sleeved around the outer periphery of the driving wheel 21 and the driven wheel 11. Of course, in other embodiments, the tension adjusting device can also be used in other mechanisms requiring tension.

[0049] The tension adjustment device includes a base 100, a support 200, a rotating member 300, a moving member 400, and a guide member 600. The support 200 is disposed on the base 100. The rotating member 300 is rotatably disposed on the support 200, and at least a portion of the rotating member 300 is a screw 310 with threads on its outer circumference. The moving member 400 is disposed on the base 100 with its position adjustable along the axial direction of the rotating member 300. The rotating member 300 is connected to the moving member 400. Rotating the rotating member 300 drives the moving member 400 away from the support 200. A first support portion 221 is formed on the side of the support 200 away from the moving member 400. A second support portion 421 is formed on the side of the moving member 400 away from the support 200. The guide member 600 is disposed on the base 100 and is used to guide the moving member 400 to move axially along the rotating member 300 and to restrict the rotation of the moving member 400. In use, the first support 221 and the second support 421 are both located between the abutment part 12 of the cutter holder 10 and the active seat 20. The first support 221 abuts against the abutment part 12 of the cutter holder 10, and the second support 421 abuts against the active seat 20. By rotating the rotating part 300, the distance between the bracket 200 and the moving part 400 can be easily adjusted, thereby adjusting the distance between the first support 221 and the second support 421, and completing the adjustment of the tension of the belt 30. This improves assembly efficiency, ensures the consistency of the tension of each belt 30, and reduces the problem of insufficient tension of the belt 30.

[0050] The rotating component 300 is rotatably connected to the support 200, and its movement along its own axial direction is restricted. The moving component 400 is provided with an adjusting screw hole, and the screw 310 is threaded into the adjusting screw hole. Rotating the rotating component 300 drives the moving component 400 to move closer to or away from the support 200. During the rotation of the rotating component 300, its position does not change, which helps to improve the convenience of operation. Furthermore, a turntable 320 is provided at the end of the rotating component 300. The diameter of the turntable 320 is larger than the diameter of the screw 310 to increase the operating lever arm and reduce the force required to rotate the rotating component 300, further improving the convenience of operation.

[0051] The tension adjustment device also includes a bearing 500, which is located between the bracket 200 and the rotating component 300. The bearing 500 reduces the relative friction between the bracket 200 and the rotating component 300, thereby further improving the smoothness of the rotation of the rotating component 300. The bracket 200 has a mounting channel in which the bearing 500 is fixed. The mounting channel is a stepped hole, with the bearing 500 located in the larger hole. The diameter of the smaller hole in the mounting channel is smaller than the outer diameter of the bearing 500's outer ring but larger than its inner diameter. A fastening screw 510 engages with a threaded hole on the bracket 200, with the nut abutting against the outer ring of the bearing 500 to lock the bearing 500 to the bracket 200. The fastening screw 510 is an M3*6 screw. Two fastening screws 510 are spaced apart along the height direction of the base 100.

[0052] In other embodiments, the rotating member 300 and the support 200 are threaded together, and the end of the rotating member 300 abuts against the movable member 400. During the rotation of the rotating member 300, it moves relative to the support 200, thereby driving the movable member 400 to move.

[0053] In some embodiments, the bracket 200 includes a support body 210 and a first protrusion 220 disposed at one end of the support body 210, and the movable member 400 includes a movable body 410 and a second protrusion 420 disposed at one end of the movable body 410. A first support portion 221 is formed on the side of the first protrusion 220 opposite to the second protrusion 420, and a second support portion 421 is formed on the side of the second protrusion 420 opposite to the first protrusion 220. The first protrusion 220 and the second protrusion 420 are convenient to extend into deeper positions, thereby adapting to narrow adjustment spaces. The width of the first protrusion 220 is smaller than the width of the support body 210. The width of the second protrusion 420 is smaller than the width of the movable body 410. Further, along the width direction of the base 100, the sidewall of one side of the second protrusion 420 is flush with the sidewall of one side of the movable body 410; along the width direction of the base 100, the sidewall of one side of the first protrusion 220 is flush with the sidewall of one side of the support body 210. The first protrusion 220 and the second protrusion 420 are both plate-shaped structures, which makes the first support 221 and the second support 421 both planar structures, which facilitates docking and improves adjustment efficiency.

[0054] A first notch is provided on the side of the support body 210 adjacent to the first protrusion 220 to avoid the driven wheel 11. A second notch is provided on the side of the movable body 410 adjacent to the second protrusion 420 to avoid the driving wheel 21.

[0055] In some embodiments, the end of the first protrusion 220 away from the base 100 has a barb (not shown in the figure) with an opening facing the base 100. When in use, it can hook onto the abutment 12 to improve the connection stability of the tension adjustment device and the cutting mechanism and prevent the tension adjustment device from falling off during the adjustment process.

[0056] To improve the reliability of the movement trajectory of the moving part 400, in some embodiments, the tension adjusting device further includes a moving body 410 and a guide member 600, one of which has a guide groove 411 and the other has a guide protrusion, with the guide protrusion slidingly engaging with the guide groove 411. Specifically, the tension adjusting device includes two guide members 600, which are spaced apart along a direction perpendicular to the axis of the rotating part 300. Each guide member 600 includes a guide vertical plate 610 and a guide horizontal plate 620. The guide vertical plate 610 is disposed on the base 100, and the guide horizontal plate 620 forms a guide protrusion. Each side of the moving body 410 has a guide groove 411, and the two guide protrusions are arranged opposite each other and correspond one-to-one with the two guide grooves 411. The two guide vertical plates 610 are respectively disposed on both sides of the base 100 along the width direction of the base 100. During the movement, the movable part 400 moves along the guide protrusion. The cooperation between the guide protrusion and the guide groove 411 prevents the movable part 400 from detaching from the base 100 upwards. In the width direction of the base 100, the movable part 400 is restricted between the two guide plates 610 to prevent the movable part 400 from separating from the base 100 in the width direction.

[0057] In some embodiments, the guide plate 610 is screwed onto the base 100. The guide plate 610 has guide holes, and the base 100 has guide screw holes. A guide screw 630 passes through the guide holes and is screwed into them. There are two guide holes, spaced apart along the length of the base 100, and two guide screw holes, corresponding one-to-one with the two guide holes. The guide holes are elongated holes extending vertically to facilitate adjustment of the position of the guide plate 610 relative to the base 100 in the height direction. The guide screw 630 is an M3x6 hexagonal flat-head screw. In this embodiment, the length direction of the base 100 is the axial direction of the rotating component 300.

[0058] To ensure the accuracy of the moving position of the movable component 400, in some embodiments, the tension adjustment device further includes a scale 700, which is disposed on the guide component 600 or the base 100. Specifically, the scale 700 is on the guide plate 610 of the guide component 600 and extends along the axial direction of the rotating component 300. The scale 700 is screwed to the guide plate 610 by a scale screw 710. The scale screw 710 is an M2*4 hexagon socket head cap screw. The moving distance of the movable component 400 can be accurately determined through the scale lines on the scale 700, improving the accuracy of the moving distance of the movable component 400; it also helps to ensure the consistency of different devices during the adjustment process and the consistency of the belt 30 tension. In some embodiments, the distance between the movable component 400 and the support 200 ranges from 10mm to 100mm. For example, the minimum distance between the movable component 400 and the support 200 is 16mm, and the maximum distance between the movable component 400 and the support 200 is 88mm. Therefore, the measuring range of the 700 scale is greater than or equal to 72 mm.

[0059] The bracket 200 has a fixing screw hole, and the base 100 has a mounting hole 110. A fixing screw 120 passes through the mounting hole 110 and is threaded into the fixing screw hole. The fixing screw 120 is an M4*12 socket head cap screw. Further, the mounting hole 110 is a strip-shaped hole extending along the axis of the rotating component 300 to accommodate different types of cutting mechanisms or other equipment requiring tension adjustment. Even further, the mounting hole 110 is a countersunk hole. To ensure connection stability, in some embodiments, two mounting holes 110 are provided, spaced apart along the width of the base 100. Two fixing screw holes are provided, with each fixing screw 120 corresponding to one of the two mounting holes 110 and the two fixing screw holes.
