Figure 2The position of the first roller 2 relative to the hydraulic cylinder 8 is on the left, and vice versa. The terms "center", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] Specifically, the tension roller is usually used to control the tension of objects such as stainless steel belts or ropes to ensure that the objects maintain an appropriate tension state during transportation. The tension roller is arranged above or below the stainless steel belt, and the tension roller is controlled to approach or move away from the stainless steel belt by providing a driving force in the vertical direction of the tension roller. The reciprocating drive member is used to control the tension roller to move closer to or farther from the stainless steel belt to adjust the tension of the stainless steel belt. This is a prior art and will not be described in detail. One of the core innovations of the utility model is that Figure 2 As shown, the first roller body 2 is horizontally slidably set on the frame 1, and the second roller body 3 is rotatably set on the side wall of the frame 1, and the stainless steel belt is wound from the bottom of the second roller body 3 to the top of the first roller body 2. The purpose of such a setting is that when adjusting the tension of the stainless steel belt, the first roller body 2 is controlled to move horizontally in the direction close to the stainless steel belt (that is, move to the left), and cooperate with the second roller body 3, so as to provide a larger tension, and the first roller body 2 is controlled to move in the direction away from the stainless steel belt (that is, move to the right), and cooperate with the second roller body 3, so as to provide a smaller tension. In addition, since the first roller body 2 only performs horizontal reciprocating motion during the adjustment process, the driving force required for the first roller body 2 during the adjustment process can be reduced.

[0031] Preferably, the frame 1 is provided with two slide grooves 4, each of which is slidably provided with a bracket 5, and the two brackets 5 are provided with a rotating hole 6, and the two ends of the first roller body 2 are rotatably connected to the two rotating holes 6 respectively. Specifically, a sliding portion is provided at the bottom end of the bracket 5, so that the bracket 5 can drive the first roller body 2 to move horizontally, and is connected to the rotating hole 6 through the end of the first roller body 2, so that the first roller body 2 itself rotates.

[0032] Preferably, the bracket 5 is L-shaped, that is, the bracket 5 includes a vertical section and a horizontal section, the bottom end of the vertical section is slidably connected to the slide groove 4, and the first roller body 2 is rotatably connected to the end of the horizontal section. During the sliding process of the bracket 5, the end of the horizontal section can extend to the outside of the frame 1, thereby increasing the moving distance of the first roller body 2, and further increasing the adjustment range of the tension of the stainless steel belt.

[0033] Preferably, a transmission plate 7 is provided between the two brackets 5, and a hydraulic cylinder 8 is provided on the frame 1, and the output end of the hydraulic cylinder 8 is fixedly connected to the transmission plate 7. Specifically, the transmission plate 7 is horizontally arranged, and its two ends are respectively fixedly connected to the opposite surfaces of the two brackets 5. The hydraulic cylinder 8 is horizontally arranged, and the horizontal position of the transmission plate 7, the bracket 5 and the first roller body 2 can be adjusted by controlling the extension and retraction of the output end of the hydraulic cylinder 8.

[0034] Furthermore, the bracket 5 is provided with an oil supply mechanism; the oil supply mechanism includes an oil storage tank 9, a horizontal groove 10 is provided on the bracket 5, an oil outlet hole 11 is provided on the inner bottom wall of the oil storage tank 9, the oil storage tank 9 is dynamically sealed and connected to the horizontal groove 10, a transfer groove 12 is provided on the inner bottom wall of the horizontal groove 10, a first channel 13 is provided inside the bracket 5, and the two ends of the first channel 13 are respectively connected to the rotating hole 6 and the transfer groove 12; it also includes a power component for driving the oil outlet hole 11 to communicate with the transfer groove 12, specifically, the horizontal groove 10 is provided on the upper surface of the horizontal section of the bracket 5, the inside of the oil storage tank 9 is filled with lubricating oil, and a connecting portion is provided at the bottom end of the oil storage tank 9, and the connecting portion is slidably connected to the horizontal groove 10 Then, the oil outlet hole 11 passes through the connecting part and is connected with the horizontal groove 10. The transfer groove 12 is opened on the inner bottom wall of the horizontal groove 10 and is located on the movement stroke of the oil outlet hole 11. The vertical height of the rotating hole 6 is smaller than the vertical height of the transfer groove 12. The power component is an existing reciprocating drive component such as an electric push rod. The purpose of such a setting is that when it is necessary to supply oil to the inside of the rotating hole 6, the oil storage tank 9 is pushed to the top of the horizontal groove 10 through the power component. At this time, the oil outlet hole 11 is located above the transfer groove 12, and the oil outlet hole 11 is connected with the transfer groove 12. The lubricating oil inside the oil storage tank 9 will flow along the oil outlet hole 11 to the inside of the transfer groove 12, and then flow to the inside of the rotating hole 6 through the first channel 13, so as to achieve the lubrication effect between the first roller body 2 and the rotating hole 6.

[0035] Furthermore, a second channel 14 is opened inside the bracket 5, and the two ends of the second channel 14 are respectively connected to the transfer groove 12 and the slide groove 4. The vertical height of the slide groove 4 is smaller than the vertical height of the transfer groove 12. The purpose of such a setting is that a part of the lubricating oil flowing into the transfer groove 12 will flow into the slide groove 4 through the second channel 14, so as to achieve a lubrication effect between the bracket 5 and the slide groove 4.

[0036] It should be noted that when the stainless steel belt is passed through the first roller body 2 and the second roller body 3, it is necessary to first control the first roller body 2 to move in a direction away from the stainless steel belt through the hydraulic cylinder 8, so that the gap between the first roller body 2 and the second roller body 3 becomes larger, thereby facilitating the passing of the stainless steel belt. That is, each time the stainless steel belt is passed through, it is necessary to control the movement of the first roller body 2 and the bracket 5. As a replacement for the above-mentioned electric push rod, the power assembly includes an abutment block 15, a vertical rod 16 is fixedly connected to the frame 1, an avoidance groove 17 is opened inside the vertical rod 16, the abutment block 15 is slidably connected to the avoidance groove 17, and the abutment block 15 A first spring 18 is arranged between the avoidance groove 17, a second spring 19 is arranged between the oil storage tank 9 and the slide groove 4, a first abutment surface 1501 is arranged on the abutment block 15, and the first abutment surface 1501 is located on the movement stroke of the oil storage tank 9. Specifically, there are two vertical rods 16, and the two vertical rods 16 are symmetrically arranged on both sides of the two brackets 5. The avoidance groove 17 is horizontally arranged at a position close to the top of the vertical rod 16. The first spring 18 is arranged between the abutment block 15 and the avoidance groove 17, and the second spring 19 is arranged between the right side of the connecting part and the right side wall of the horizontal groove 10, and is in a compressed state, and the first spring 18 The stiffness coefficient is greater than that of the second spring 19. The first abutting surface 1501 is an inclined surface and is located at the end of the abutting block 15 away from the avoidance groove 17. The effect of such a setting is that when the hydraulic cylinder 8 drives the bracket 5 to move horizontally, it will drive the left edge of the oil storage tank 9 to abut against the first abutting surface 1501. Since the stiffness coefficient of the first spring 18 is greater than that of the second spring 19, when the first abutting surface 1501 abuts against the oil storage tank 9, the oil storage tank 9 will slide to the right relative to the horizontal groove 10, so that the oil outlet 11 is connected with the transfer groove 12, and the second spring 19 is squeezed. When the second spring 19 is squeezed to the limit position, That is, at this time, under the limiting action of the right side wall of the horizontal groove 10, the oil storage tank 9 cannot continue to slide relative to the horizontal groove 10. At this time, the abutment between the first abutment surface 1501 and the oil storage tank 9 will cause the abutment block 15 to slide toward the inside of the avoidance groove 17 and squeeze the first spring 18 to achieve avoidance. After the oil storage tank 9 is away from the first abutment surface 1501, the abutment block 15 automatically resets under the action of the first spring 18, and the oil storage tank 9 slides to the leftmost end of the horizontal groove 10 under the action of the second spring 19 to achieve automatic reset. In this way, each time the position of the first roller body 2 is adjusted, passive oil supply can be performed to the rotating hole 6 and the inside of the slide groove 4.

[0037] Furthermore, a second abutment surface 1502 is provided on the abutment block 15, and the second abutment surface 1502 is located on the movement stroke of the oil storage tank 9. The second abutment surface 1502 is also an inclined surface, which is symmetrically arranged opposite to the first abutment surface 1501. When the hydraulic cylinder 8 drives the bracket 5 to return, the second abutment surface 1502 abuts against the right edge of the oil storage tank 9. Since the oil storage tank 9 is located at the leftmost end of the horizontal groove 10 at this time, that is, the oil storage tank 9 cannot slide relative to the horizontal groove 10 at this time, when the oil storage tank 9 abuts against the second abutment surface 1502, the abutment block 15 will slide into the avoidance groove 17 and squeeze the first spring 18 to achieve avoidance. When the oil storage tank 9 is away from the second abutment surface 1502, the abutment block 15 automatically resets under the elastic force of the first spring 18 to prepare for the next abutment.

[0038] Preferably, the oil storage tank 9 is provided with a threaded cover 20 , and an opening is provided at the top of the oil storage tank 9 . The threaded cover 20 is screwed to open and close the opening of the oil storage tank 9 , thereby facilitating the addition of lubricating oil into the oil storage tank 9 .

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
