Description

Technical Field

[0001] The present application relates to the field of carpet production, and in particular to a U-shaped storage rack 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 square carpet is generally about 50cmX50cm in size. 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, the carpet production line mainly includes an unwinding drum, a traction machine and a compounding mechanism. Usually, the grey carpet cloth roll and the carpet layer roll are placed on the unwinding drum, and the traction machine is used to lead the grey carpet cloth and the carpet layer through the compounding mechanism at the same time. The compounding mechanism compounds the carpet layer with the grey carpet cloth to form a carpet, and then the carpet is cooled, trimmed and cut to form a square carpet.

[0004] The above-mentioned related technologies have the following defects: the traction machine directly pulls the grey blanket roll to the composite mechanism. As the grey blanket roll is unwound, the grey blanket roll gradually shrinks, and the traction force of the traction machine gradually changes, so that during the production process of the carpet, the front and rear tensions of the grey blanket cloth are uneven, and the tensions between the layers of the carpet are different. Then, when the carpet roll is subsequently cut into square carpets, the square carpets are prone to deformation or warping after being used for a period of time. Utility Model Content

[0005] In order to prevent the square carpet from being easily deformed or warped, the present application provides a U-shaped storage rack for a square carpet production line.

[0026] The limiting member is located at a side of the guide roller away from the first traction machine, and the limiting members on both sides are spaced apart in the width direction of the main frame.

[0027] By adopting the above technical solution, the two limiting members clamp the green blanket cloth to define the relative position of the green blanket cloth and the main support, and the guide roller is used to guide the green blanket cloth into the first traction machine.

[0028] Optionally, the first traction machine includes a first conveying roller, a second conveying roller and two first side brackets, and in the width direction of the main body bracket, the two first side brackets are installed on the main body bracket at intervals;

[0043] By adopting the above technical solution, when the grey blanket passes through the first swing roller and the second swing roller, the first swing roller and the second swing roller will be pressed to rotate under the tension of the grey blanket, thereby driving the movable bracket to rotate and causing the reset spring to expand and contract. The reset spring can drive the movable bracket to reset, thereby causing the first swing roller and the second swing roller to elastically press the grey blanket, so that the grey blanket has appropriate tension during the conveying process. The feed guide assembly is located below the first tractor, and the tension adjustment assembly is located below the second tractor, so that the grey blanket can be pressed on the first conveying roller when passing through the first tractor and the second tractor. At this time, it is only necessary to adjust the height of the second conveying roller to achieve the clamping and conveying of the grey blanket of different thicknesses.

[0044] In summary, the present application includes at least one of the following beneficial technical effects:

[0045] 1. In the present application, during the carpet production process, the first tractor pulls the grey blanket cloth on the grey blanket cloth roll to the storage assembly for buffering, and the second tractor pulls a section of the grey blanket cloth buffered at the storage assembly to the compounding mechanism for compounding with other carpet layers. Since each time the grey blanket cloth is conveyed to the compounding mechanism, a section of the grey blanket cloth buffered at the storage assembly is pulled, the traction force of the second tractor will not be affected by the grey blanket cloth roll. The second tractor can convey the grey blanket cloth to the compounding mechanism with a constant traction force, which can reduce the resistance encountered by the second tractor during the process of traction of the grey blanket cloth, and ensure that the carpet cloth between the storage assembly and the compounding mechanism is subjected to a relatively uniform force, so that the tension between the grey blanket cloth and other carpet layers during compounding can be nearly equal, thereby reducing the subsequent warping of the square carpet.

[0046] 2. In the present application, the first traction machine can continuously transport the grey blanket cloth on the unwinding drum to the storage rack, which is equivalent to alleviating the unstable traction force of the original traction mechanism. In this way, the second traction machine only needs to pull the grey blanket cloth in the storage rack, reducing resistance and ensuring uniform tension between layers of the carpet when compounding.

[0047] 3. In the present application, the distance between the first slider and the second slider is adjusted to achieve the clamping of the blank blanket cloth by the first conveyor roller and the second conveyor roller. The blank blanket cloth passes between the first conveyor roller and the second conveyor roller, and the first conveyor roller and the second conveyor roller rotate to achieve the clamping and conveying of the blank blanket cloth by the first conveyor roller and the second conveyor roller.

[0048] 4. In the present application, the blank blanket cloth passes through the first swing roller and the second swing roller. Under the action of the tension of the blank blanket cloth, the first swing roller and the second swing roller are pressed to rotate, thereby driving the movable bracket to rotate, so that the reset spring is extended and retracted, and the reset spring can drive the movable bracket to reset, thereby enabling the first swing roller and the second swing roller to elastically press the blank blanket cloth, so that the blank blanket cloth has appropriate tension during the conveying process.

The first tractor 3 and the second tractor 30 have the same structure.

[0069] Reference Figure 1 and Figure 2In the embodiment of the present application, during the carpet production process, the first tractor 3 pulls the blank blanket cloth 6 on the blank blanket cloth 6 roll to the storage assembly 4 for buffering, and the second tractor 30 pulls a section of the blank blanket cloth 6 buffered at the storage assembly 4 to the composite mechanism for compounding with other carpet layers. Since each time the blank blanket cloth 6 is conveyed to the composite mechanism, a section of the blank blanket cloth 6 buffered at the storage assembly 4 is pulled, the traction force of the second tractor 30 will not be affected by the blank blanket cloth 6 roll, and the second tractor 30 can convey the blank blanket cloth 6 to the composite mechanism with a constant traction force, so that the overall tension of the formed carpet is evenly distributed, which can reduce the resistance encountered by the second tractor 30 in the process of pulling the blank blanket cloth, and ensure that the carpet cloth between the storage assembly 4 and the composite mechanism is subjected to a relatively uniform force, so that the tension between the blank blanket cloth and other carpet layers during compounding can be nearly equal, and the subsequent warping of the square carpet can be reduced.

[0070] Reference Figure 1 and Figure 2 The material storage assembly 4 includes a material storage rack 41, which is mounted on the main frame 1 and is provided with a material storage trough 4101. The notch of the material storage trough 4101 is arranged opposite to the first tractor 3 and the second tractor 30. In the embodiment of the present application, the first tractor 3 pulls the grey blanket cloth 6 on the roll to the material storage trough 4101 for buffering.

[0071] Reference Figure 1 and Figure 2 A feed guide assembly 2 is provided on the main support 1. The feed guide assembly 2 is located on the side of the first tractor 3 away from the second tractor 30, and is also located below the first tractor 3. The feed guide assembly 2 includes a guide roller 21 and two limit members 22. The guide roller 21 is arranged along the width direction of the main support 1 and is rotatably mounted on the main support 1. The limit members 22 are located on the side of the guide roller 21 away from the first tractor 3. In the width direction of the main support 1, the limit members 22 on both sides are spaced apart. In the embodiment of the present application, the two limit members 22 clamp the blank blanket cloth 6 to limit the relative position of the blank blanket cloth 6 and the main support 1. The guide roller 21 is used to guide the blank blanket cloth 6 into the first tractor 3.

[0072] Reference Figure 1 and Figure 2The first tractor 3 includes a first conveying roller 34, a second conveying roller 35 and two first side brackets 31. In the width direction of the main body bracket 1, the two first side brackets 31 are installed on the main body bracket 1 at intervals. The first side bracket 31 is provided with a vertically arranged side slide groove 3101, and the inner side of the side slide groove 3101 is provided with a first slider 32 and a second slider 33 distributed vertically at intervals. The first slider 32 and the second slider 33 are both slidably connected to the first side bracket 31, and the second slider 33 is arranged above the first slider 32. The first conveying roller 34 and the second conveying roller 35 are both arranged along the width direction of the main body bracket 1. The two first sliders 32 are rotatably connected to the two ends of the first conveying roller 34, respectively, and the two second sliders 33 are rotatably connected to the two ends of the second conveying roller 35, respectively.

[0073] Reference Figure 1 and Figure 2 In the embodiment of the present application, the spacing between the first slider 32 and the second slider 33 is adjusted to achieve the clamping of the blank blanket cloth 6 by the first conveyor roller 34 and the second conveyor roller 35. The blank blanket cloth 6 passes between the first conveyor roller 34 and the second conveyor roller 35, and the first conveyor roller 34 and the second conveyor roller 35 rotate to achieve the clamping and conveying of the blank blanket cloth 6 by the first conveyor roller 34 and the second conveyor roller 35.

[0074] Reference Figure 1 and Figure 2 Optionally, the first slider 32 and the second slider 33 can be detachably connected to the first side bracket 31. In the embodiment of the present application, after adjusting the distance between the first slider 32 and the second slider 33, the first slider 32 and the second slider 33 can be detachably connected to the first side bracket 31 to limit the relative positions of the first slider 32 and the second slider 33.

[0075] Reference Figure 1 and Figure 2 A lifting member 331 is connected between the second slider 33 and the first side bracket 31. In the embodiment of the present application, when the blank blanket cloth 6 passes between the first conveying roller 34 and the second conveying roller 35, the height of the second conveying roller 35 is lowered by the lifting member 331, so that the second conveying roller 35 is pressed on the first conveying roller 34, thereby clamping the blank blanket cloth 6.

[0076] Reference Figure 1 and Figure 2The main support 1 is provided with a tension adjustment assembly 5, which is located on the side of the second tractor 30 away from the first tractor 3 and below the second tractor 30. The tension adjustment assembly 5 includes a rotating shaft 52, a movable bracket 53, a first swing roller 54, a second swing roller 55 and a return spring 56. The rotating shaft 52 is arranged along the width direction of the main support 1. The second side bracket 51 is connected between both ends of the rotating shaft 52 and the main support 1, and the rotating shaft 52 is rotatably mounted on the second side bracket 51. The movable bracket 53 is radially mounted on the rotating shaft 52. The first swing roller 54 and the second swing roller 55 are symmetrically arranged on both sides of the rotating shaft 52, and both can be rotatably mounted on the movable bracket 53. The return spring 56 is arranged on the side of the rotating shaft 52, and one end is connected to the movable bracket 53, and the other end is connected to the main support 1 and / or the second side bracket 51.

[0077] Reference Figure 1 and Figure 2 In the embodiment of the present application, the grey blanket cloth 6 passes through the first swing roller 54 and the second swing roller 55. Under the action of the tension of the grey blanket cloth 6, the first swing roller 54 and the second swing roller 55 are pressed to rotate, thereby driving the movable bracket 53 to rotate, causing the reset spring 56 to retract. The reset spring 56 can drive the movable bracket 53 to reset, thereby enabling the first swing roller 54 and the second swing roller 55 to effectively press the grey blanket cloth 6, so that the grey blanket cloth 6 has appropriate tension during the conveying process. The feed guide assembly 2 is located below the first tractor 3, and the tension adjustment assembly 5 is located below the second tractor 30, so that the grey blanket cloth 6 can be pressed on the first conveying roller 34 when passing through the first tractor 3 and the second tractor 30. At this time, it is only necessary to adjust the height of the second conveying roller 35 to achieve the clamping and conveying of the grey blanket cloth 6 of different thicknesses.

[0078] The implementation principle of a U-shaped storage rack of a carpet tile production line in the present application embodiment is as follows:

[0079] The relative positions of the main support 1 and the composite mechanism are adjusted by the cooperation of the roller 112 on the slide rail 111, so that the blank blanket cloth 6 can be located in the middle of the guide roller 21, the first conveying roller 34, the second conveying roller 35, the first swing roller 54 and the second swing roller 55 during transportation. Even if the blank blanket cloth 6 is offset, it is not easy to be offset to the outside of the guide roller 21, the first conveying roller 34, the second conveying roller 35, the first swing roller 54 and the second swing roller 55.

[0080] The blank blanket cloth 6 passes through between two stoppers 22, the guide roller 21, the first tractor 3, the material storage tank 4101, the second tractor 30 and the tension adjustment assembly 5 in sequence, and then enters the composite mechanism.

[0081] During the carpet production process, the first tractor 3 pulls the grey blanket cloth 6 on the grey blanket cloth 6 roll to the storage tank 4101 for buffering, and the second tractor 30 pulls a section of the grey blanket cloth 6 buffered in the storage tank 4101 to the composite mechanism for compounding with other carpet layers. Since each time the grey blanket cloth 6 is conveyed to the composite mechanism, a section of the grey blanket cloth 6 buffered in the storage tank 4101 is pulled, the traction force of the second tractor 30 will not be affected by the grey blanket cloth 6 roll. The second tractor 30 can convey the grey blanket cloth 6 to the composite mechanism with a constant traction force, so that the overall tension of the formed carpet is evenly distributed, thereby improving the quality of the carpet.

[0082] Embodiment 2

[0083] Reference Figure 3 and Figure 4 The difference between the second embodiment and the first embodiment is that the material storage assembly 4 includes a U-shaped plate 42, which is arranged along the width direction of the main frame 1 and connected to the main frame 1. The U-shaped groove 4201 of the U-shaped plate 42 is arranged opposite to the first tractor 3 and the second tractor 30. In the embodiment of the present application, the first tractor 3 pulls the blank blanket cloth 6 on the roll of the blank blanket cloth 6 into the U-shaped groove 4201 for buffering. In addition, both ends of the U-shaped plate 42 are open, so as to facilitate the observation of the buffering state of the blank blanket cloth 6.

[0084] The implementation principle of the U-shaped storage rack of the square carpet production line in the embodiment of the present application is: by cooperating with the roller 112 on the slide rail 111, the relative position of the main support 1 and the composite mechanism is adjusted so that the blank blanket cloth 6 can be located in the middle of the guide roller 21, the first conveying roller 34, the second conveying roller 35, the first swing roller 54 and the second swing roller 55 during transportation. Even if the blank blanket cloth 6 is offset, it is not easy to offset outside the guide roller 21, the first conveying roller 34, the second conveying roller 35, the first swing roller 54 and the second swing roller 55.

[0085] The blank blanket cloth 6 passes through between two stoppers 22, the guide roller 21, the first tractor 3, the U-shaped groove 4201, the second tractor 30 and the tension adjustment assembly 5 in sequence, and then enters the composite mechanism.

[0086] Furthermore, during the carpet production process, the first tractor 3 pulls the grey blanket cloth 6 on the grey blanket cloth 6 roll into the U-shaped groove 4201 for buffering, and the second tractor 30 pulls a section of the grey blanket cloth 6 buffered in the U-shaped groove 4201 to the composite mechanism for compounding with other carpet layers. Since each time the grey blanket cloth 6 is conveyed to the composite mechanism, a section of the grey blanket cloth 6 buffered in the U-shaped groove 4201 is pulled, the traction force of the second tractor 30 will not be affected by the grey blanket cloth 6 roll. The second tractor 30 can convey the grey blanket cloth 6 to the composite mechanism with a constant traction force, so that the overall tension of the formed carpet is evenly distributed, thereby improving the quality of the carpet.
