Abstract
Description
Technical Field
[0001] The present application relates to the field of carpet production, and in particular to a tension adjustment mechanism for a square carpet production line. Background Art
[0002] At present, various square carpets can often be seen in some offices or high-end places. The common size of square carpets is generally about 50cmX50cm. Compared with the traditional larger carpet, this small patchwork carpet can be laid on the ground like floor tiles. It is not only easy to carry, but the key is that users can lay or clean it by themselves, which is very popular among modern people.
[0003] In the related art, during the production process of carpets, a square carpet production line first pulls the carpet layer roll on the unwinding drum to a compounding mechanism, which compounds multiple carpet layers together to form a carpet. The carpet is then cooled and shaped to solidify the glue used for compounding the multiple carpet layers. The carpet is shaped into a finished product, and finally the carpet is trimmed and cut to form a square carpet.
[0004] The above-mentioned related technologies have the following defects: during the production process of the carpet, the carpet layer on the unwinding drum will gradually shrink when unwinding, which will cause the traction force of the carpet layer to gradually change, resulting in different tensions of the carpet layers, which can easily cause the edges of the cut square carpet to curl up. Utility Model Content
[0005] In order to automatically adjust the tension of a carpet during the carpet production process, the present application provides a tension adjustment mechanism for a square carpet production line.
[0006] The present application provides a carpet tile production line tension adjustment mechanism that adopts the following technical solution:
[0007] A tension adjustment mechanism for a carpet tile production line comprises a bracket, a first rotating shaft, a reversing roller, a swing arm and a swing roller, wherein the first rotating shaft is rotatably mounted on the bracket;
[0008] The reversing roller is coaxially and rotatably mounted on the first rotating shaft;
[0009] The swing roller is arranged on a side of the reversing roller away from the bracket, is located below the reversing roller, and is also parallel to the reversing roller;
[0010] The swing arm is arranged on the side of the reversing roller, and one end of the swing arm is rotatably connected to the bracket, and the other end of the swing arm is rotatably connected to the swing roller;
[0011] A torsion spring is connected between the swing arm and the bracket, and the torsion spring is used to reset the swing arm after rotation.
[0012] By adopting the above technical solution, the tension adjusting mechanism is arranged before the step of cooling and shaping the carpet. When the carpet passes through the tension adjusting mechanism, it is arranged downward, and after passing through the reversing roller and the swing roller in sequence, it is arranged upward. During the transportation of the carpet, the carpet will contact the swing roller. As the tension of the carpet increases, the carpet at the swing roller will be gradually straightened, thereby pushing the swing roller to rotate upward. As the tension of the carpet decreases, the carpet at the swing roller will lower its height and move away from the swing roller. However, under the action of the self-weight of the swing roller and the torsion force of the torsion spring, the swing roller will be driven to rotate downward, so that no matter how the height of the carpet at the swing roller changes, the swing roller can adaptively adjust its height and effectively press on the carpet, thereby enabling the carpet to have an effective and relatively uniform tension during the conveying process, making the tensions of each layer of the formed carpet close to the same, and making it not easy for the edges of the cut square carpet to warp.
[0013] Optionally, a connection hole is provided at one end of the swing arm away from the reversing roller;
[0014] The first rotating shaft is coaxially arranged in the connection hole, and the swing arm is rotatably connected to the first rotating shaft through the connection hole.
[0015] By adopting the above technical solution, the swing arm realizes rotatable connection with the first rotating shaft through the connection hole.
[0016] Optionally, the torsion spring is sleeved on the first rotating shaft, and one end is connected to the first rotating shaft, and the other end is connected to the swing arm.
[0017] By adopting the above technical solution, the setting of the torsion spring provides a stable reset function, which helps to maintain the continuity and precise control of the carpet tension. And if the actual required tension adjustment range of the carpet exceeds the adjustment range of the torsion spring, the height of the swing roller can be adjusted significantly by rotating the first rotating shaft first, and then the swing roller can be elastically contacted with the carpet through the torsion spring to ensure the uniformity of the overall tension during the carpet production process.
[0018] Optionally, the swing roller includes a second rotating shaft, a first round tube and a second round tube, and the second rotating shaft is rotatably connected to the bracket;
[0019] The first round tube is coaxially sleeved on the second rotating shaft and is rotatably connected to the second rotating shaft;
[0020] The second round tube is coaxially sleeved on the first round tube and is rotatably connected to the first round tube;
[0021] A plurality of pressure sensors are connected between the first round tube and the second round tube;
[0022] In the length direction of the first circular tube, multiple groups of the pressure sensors are distributed at intervals.
[0023] Each group of the pressure sensors includes a plurality of the pressure sensors that are distributed at intervals along the circumferential direction of the first circular tube.
[0024] By adopting the above technical solution, the pressure borne by the second circular tube is detected by the pressure sensor, and then the tension condition of the carpet is judged. If the actual required tension of the carpet does not exceed the adjustment range of the torsion spring, the tension of the carpet is adjusted by the torsion spring. If the actual required tension of the carpet exceeds the adjustment range of the torsion spring, and if the carpet tension is too low, the first rotating shaft is rotated to rotate the swing roller downward, and the pressing force of the swing roller on the carpet is roughly adjusted first, and then the swing roller is made to swing adaptively through the torsion spring and elastically contact the carpet to ensure the uniformity of the overall tension during the carpet production process. If the carpet tension is too high, the first rotating shaft is rotated to rotate the swing roller upward, and the pressing force of the swing roller on the carpet is roughly adjusted first, and then the swing roller is made to swing adaptively through the torsion spring and elastically contact the carpet to ensure the uniformity of the overall tension during the carpet production process.
[0025] Optionally, a motor is connected between one end of the first rotating shaft and the bracket.
[0026] By adopting the above technical solution, the first rotating shaft is automatically driven to rotate by the motor, and then the first rotating shaft drives the swing arm to rotate through the torsion spring.
[0027] Optionally, a counterweight is provided at one end of the swing arm away from the bracket.
[0028] By adopting the above technical solution, the counterweight further enhances the resetting force of the torsion spring.
[0029] Optionally, a vertically arranged chute is provided at one end of the swing arm away from the bracket;
[0030] An adjusting component is provided at one end of the swing arm away from the bracket. The adjusting component includes a slider. The slider is arranged in the chute and is slidably connected to the bracket through the chute;
[0031] The swing roller is rotatably connected to the slider.
[0032] By adopting the above technical solution, the swing roller is driven to lift by the lifting of the slider in the chute, further improving the adjusting ability of the swing roller.
[0033] Optionally, a lead screw is connected between the slider and the bracket. The lead screw is arranged along the length direction of the chute, and one end is rotatably connected to the slider and the other end is screwed to the bracket.
[0034] By adopting the above technical solution, the lead screw is rotated to drive the slider to lift in the chute.
[0035] Optionally, a telescopic member is connected between the slider and the bracket, and the telescopic member is arranged along the length direction of the chute.
[0036] By adopting the above technical solution, the slider is driven to lift in the chute by the telescopic member's expansion and contraction.
[0037] In summary, the present application includes at least one of the following beneficial technical effects:
[0038] 1. In the present application, under the action of the self-weight of the swing roller and the torsion force of the torsion spring, no matter how the height of the carpet at the swing roller changes, the swing roller can adaptively adjust its height and effectively press on the carpet. As a result, the carpet has an effective and relatively uniform tension during the conveying process, making the tension of each layer of the carpet after forming close to the same, and making it not easy for the edges of the cut square carpet to warp.
[0039] 2. In the present application, the pressure sensor is used to detect the pressure borne by the second circular tube, and then the tension condition of the carpet is judged. When the actual required tension of the carpet does not exceed the adjustment range of the torsion spring, the torsion spring is used to adjust the tension of the carpet. When the actual required tension of the carpet exceeds the adjustment range of the torsion spring, first, the first rotating shaft is rotated to rotate the swing roller, and then the swing roller is made to swing adaptively through the torsion spring to elastically contact the carpet, ensuring the uniformity of the overall tension during the carpet production process.
[0040] 3. In the present application, the slider lifts in the chute, thereby driving the swing roller to lift, further improving the adjustment ability of the swing roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will further elaborate on this application in conjunction with the attached Figures 1-3 drawings.
[0048] An embodiment of this application discloses a tension adjusting mechanism for a square carpet production line.
[0049] Embodiment 1
[0050] Referring to Figure 1 , a tension adjusting mechanism for a square carpet production line includes a bracket 1, a first rotating shaft 2, a reversing roller 21, a swing arm 3, and an oscillating roller 4. The first rotating shaft 2 is rotatably installed on the bracket 1. The reversing roller 21 is coaxially and rotatably installed on the first rotating shaft 2. The oscillating roller 4 is arranged on the side of the reversing roller 21 away from the bracket 1, and is located below the reversing roller 21 and is also parallel to the reversing roller 21. The swing arm 3 is arranged on the side of the reversing roller 21, and one end is provided with a connecting hole 301. The first rotating shaft 2 is coaxially arranged in the connecting hole 301. The swing arm 3 is rotatably connected to the first rotating shaft 2 through the connecting hole 301, and the other end is rotatably connected to the oscillating roller 4. A torsion spring 31 is connected between the swing arm 3 and the bracket 1. The torsion spring 31 is used to reset the rotated swing arm 3.
[0051] Referring to Figure 1 , in the implementation mode of this application, the tension adjusting mechanism is arranged before the step of cooling and shaping the carpet. When the carpet passes through the tension adjusting mechanism, it is arranged downward, and after passing through the reversing roller 21 and the oscillating roller 4 in sequence, it is then arranged upward. During the transportation of the carpet, the carpet will contact the oscillating roller 4. As the tension of the carpet increases, the carpet at the oscillating roller 4 will be gradually straightened, thereby pushing the oscillating roller 4 to rotate upward. As the tension of the carpet decreases, the carpet at the oscillating roller 4 will lower its height and move away from the oscillating roller 4. However, under the action of the self-weight of the oscillating roller 4 and the torsion of the torsion spring 31, both will drive the oscillating roller 4 to rotate downward, so that no matter how the height of the carpet at the oscillating roller 4 changes, the oscillating roller 4 can adaptively adjust its height and effectively press on the carpet, so that the carpet has an effective and relatively uniform tension during transportation, making the tension of each layer of the formed carpet close to the same, and making it not easy for the edges of the cut square carpet to warp.
[0052] Referring to Figure 1, the torsion spring 31 is sleeved on the first rotating shaft 2, with one end connected to the first rotating shaft 2 and the other end connected to the swing arm 3. In the embodiment of the present application, the setting of the torsion spring 31 provides a stable reset function, which helps to maintain the continuity and precise control of the carpet tension. Moreover, if the actual required tension adjustment range of the carpet exceeds the adjustment range of the torsion spring 31, the height of the swing roller 4 can be adjusted significantly by rotating the first rotating shaft 2 first, and then the swing roller 4 is elastically contacted with the carpet through the torsion spring 31 to ensure the uniformity of the overall tension during the carpet production process.
[0053] Refer to Figure 1 , the swing roller 4 includes a second rotating shaft 41, a first circular tube 42 and a second circular tube 44. The second rotating shaft 41 is rotatably connected to the bracket 1. The first circular tube 42 is coaxially sleeved on the second rotating shaft 41 and is rotatably connected to the second rotating shaft 41. The second circular tube 44 is coaxially sleeved on the first circular tube 42 and is rotatably connected to the first circular tube 42. A plurality of pressure sensors 43 are connected between the first circular tube 42 and the second circular tube 44. In the length direction of the first circular tube 42, the plurality of pressure sensors 43 are spaced apart. Each group of pressure sensors 43 includes a plurality of pressure sensors 43 spaced apart along the circumferential direction of the first circular tube 42.
[0054] Refer to Figure 1 , in the embodiment of the present application, the pressure borne by the second circular tube 44 is detected by the pressure sensor 43, and then the tension condition of the carpet is judged. If the actual required tension of the carpet does not exceed the adjustment range of the torsion spring 31, the tension of the carpet is adjusted by the torsion spring 31. If the actual required tension of the carpet exceeds the adjustment range of the torsion spring 31, and if the carpet tension is too low, the swing roller 4 is rotated downward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet first, and then the swing roller 4 is adaptively swung through the torsion spring 31 to be elastically contacted with the carpet to ensure the uniformity of the overall tension during the carpet production process. If the carpet tension is too high, the swing roller 4 is rotated upward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet first, and then the swing roller 4 is adaptively swung through the torsion spring 31 to be elastically contacted with the carpet to ensure the uniformity of the overall tension during the carpet production process.
[0055] Refer to Figure 1 , a motor 22 is connected between one end of the first rotating shaft 2 and the bracket 1. In the embodiment of the present application, the first rotating shaft 2 is automatically driven to rotate by the motor 22, and then the first rotating shaft 2 drives the swing arm 3 to rotate through the torsion spring 31.
[0056] Refer to Figure 1 , a counterweight 32 is provided at one end of the swing arm 3 away from the bracket 1. In the embodiment of the present application, the counterweight 32 further enhances the reset force of the torsion spring 31.
[0057] The implementation principle of a tension adjustment mechanism for a square carpet production line in an embodiment of the present application is as follows:
[0058] The tension adjustment mechanism is arranged before the step of cooling and shaping the carpet. When the carpet passes through the tension adjustment mechanism, it is arranged downward, and after passing through the reversing roller 21 and the swing roller 4 in sequence, it is then arranged upward.
[0059] The pressure borne by the second round tube 44 is detected by the pressure sensor 43, and then the tension condition of the carpet is judged. When the actually required tension of the carpet does not exceed the adjustment range of the torsion spring 31, the tension of the carpet is adjusted by the torsion spring 31. When the actually required tension of the carpet exceeds the adjustment range of the torsion spring 31, if the carpet tension is too low, the swing roller 4 is rotated downward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet, and then the swing roller 4 is made to swing adaptively through the torsion spring 31 to elastically contact the carpet, ensuring the uniformity of the overall tension during the carpet production process. If the carpet tension is too high, the swing roller 4 is rotated upward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet, and then the swing roller 4 is made to swing adaptively through the torsion spring 31 to elastically contact the carpet, ensuring the uniformity of the overall tension during the carpet production process.
[0060] Embodiment Two
[0061] Refer to Figure 2 , the difference between Embodiment Two and Embodiment One is that a vertically arranged chute 302 is provided at one end of the swing arm 3 away from the bracket 1. An adjusting component 5 is provided at one end of the swing arm 3 away from the bracket 1. The adjusting component 5 includes a slider 51. The slider 51 is arranged in the chute 302 and is slidably connected to the bracket 1 through the chute 302. The swing roller 4 is rotatably connected to the slider 51. In the implementation manner of the present application, the swing roller 4 is driven to lift by the lifting of the slider 51 in the chute 302, further improving the adjustment ability of the swing roller 4.
[0062] Refer to Figure 2 , a lead screw 52 is connected between the slider 51 and the bracket 1. The lead screw 52 is arranged along the length direction of the chute 302, and one end is rotatably connected to the slider 51 and the other end is screwed to the bracket 1. In the implementation manner of the present application, the lead screw 52 is driven by a servo motor, and the slider 51 is driven to lift in the chute 302 by rotating the lead screw 52.
[0063] The implementation principle of a tension adjustment mechanism for a square carpet production line in an embodiment of the present application is as follows: The tension adjustment mechanism is arranged before the step of cooling and shaping the carpet. When the carpet passes through the tension adjustment mechanism, it is arranged downward, and after passing through the reversing roller 21 and the swing roller 4 in sequence, it is then arranged upward.
[0064] The pressure borne by the second circular tube 44 is detected by the pressure sensor 43, and then the tension condition of the carpet is judged. When the actual required tension of the carpet does not exceed the adjustment range of the torsion spring 31, the tension of the carpet is adjusted by the torsion spring 31. When the actual required tension of the carpet exceeds the adjustment range of the torsion spring 31, if the carpet tension is too low, the swing roller 4 is rotated downward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet, and then the torsion spring 31 is used to make the swing roller 4 swing adaptively and elastically contact the carpet to ensure the uniformity of the overall tension during the carpet production process. If the carpet tension is too high, the swing roller 4 is rotated upward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet, and then the torsion spring 31 is used to make the swing roller 4 swing adaptively and elastically contact the carpet to ensure the uniformity of the overall tension during the carpet production process.
[0065] Moreover, by rotating the lead screw 52, the slider 51 is driven to lift in the chute 302, and then the swing roller 4 is driven to lift, further improving the adjustment ability of the swing roller 4.
[0066] Embodiment III
[0067] Refer to Figure 2 , the difference between Embodiment III and Embodiment II is that a telescopic member 53 is connected between the slider 51 and the bracket 1, and the telescopic member 53 is arranged along the length direction of the chute 302. In the implementation mode of the present application, the slider 51 is driven to lift in the chute 302 by the telescopic member 53 telescoping.
[0068] The implementation principle of the tension adjustment mechanism of the square carpet production line in the embodiment of the present application is: the tension adjustment mechanism is arranged before the step of cooling and shaping the carpet. When the carpet passes through the tension adjustment mechanism, it is arranged downward, and after passing through the reversing roller 21 and the swing roller 4 in sequence, it is arranged upward.
[0069] The pressure borne by the second circular tube 44 is detected by the pressure sensor 43, and then the tension condition of the carpet is judged. When the actual required tension of the carpet does not exceed the adjustment range of the torsion spring 31, the tension of the carpet is adjusted by the torsion spring 31. When the actual required tension of the carpet exceeds the adjustment range of the torsion spring 31, if the carpet tension is too low, the swing roller 4 is rotated downward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet, and then the torsion spring 31 is used to make the swing roller 4 swing adaptively and elastically contact the carpet to ensure the uniformity of the overall tension during the carpet production process. If the carpet tension is too high, the swing roller 4 is rotated upward by rotating the first rotating shaft 2 to roughly adjust the pressing force of the swing roller 4 on the carpet, and then the torsion spring 31 is used to make the swing roller 4 swing adaptively and elastically contact the carpet to ensure the uniformity of the overall tension during the carpet production process.
[0070] Moreover, by the telescopic movement of the telescopic member 53, the slider 51 is driven to move up and down in the chute 302, thereby driving the swing roller 4 to move up and down, further improving the adjustment ability of the swing roller 4.
