Description

Technical Field

[0001] This application relates to the field of home textile processing technology, and in particular to a roll material feeding device and home textile processing equipment. Background Technology

[0002] In the manufacturing process of home textiles, the unloading of roll materials (such as rolled zippers, cotton ropes, etc.) is fundamental to ensuring the smooth progress of subsequent processes. To address this, related technologies have proposed roll material unloading devices. In use, the roll material is fixed to a rotatable mounting structure of the unloading device. As the material is fed in, the tension acting on the material drives the roll material and the mounting structure to rotate synchronously, thus achieving automatic unloading.

[0003] However, traditional roll material unloading devices have the following problems: when unloading the roll material, uneven tension can easily cause the material to deform or even be damaged. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a roll material unloading device that can adjust the tension on the material according to the actual situation during roll material unloading.

[0005] This application also proposes a home textile processing equipment having the above-mentioned roll material feeding device.

[0006] The roll unloading device according to a first aspect embodiment of this application includes:

[0007] Base;

[0008] Mounting base, which is rotatably mounted on the base, and the mounting base is provided with a mounting structure for mounting the roll material;

[0009] A damping element is movably disposed on the base, and the bottom of the mounting base is provided with a rotating shaft rotatably connected to the base. The damping element can abut against the rotating shaft to provide a frictional force for limiting the rotational speed of the mounting base.

[0010] An adjustment mechanism is provided on the base and is used to adjust the friction between the damping element and the rotating shaft.

[0011] The roll material unloading device according to the embodiments of this application has at least the following beneficial effects: In use, the roll material is sleeved on the mounting structure. As the material is fed, the tension acting on the material drives the roll material and the mounting base to rotate synchronously, thereby achieving automatic unloading. During the unloading process: when the rotation speed of the mounting base is too fast, the unloading speed of the material exceeds the feeding speed, resulting in insufficient tension on the material. In this case, the friction between the damping element and the rotating shaft can be increased by adjusting the mechanism to reduce the rotation speed of the mounting base, thereby reducing the rotation speed of the roll material and increasing the tension on the material. When the rotation speed of the mounting base is too slow, the unloading speed of the material is less than the feeding speed, resulting in excessive tension on the material. In this case, the friction between the damping element and the rotating shaft can be reduced by adjusting the mechanism to increase the rotation speed of the mounting base, thereby increasing the rotation speed of the roll material and reducing the tension on the material. The roll material unloading device of this application can adjust the tension on the material according to the actual situation during roll material unloading, thereby helping to prevent deformation or even damage to the material due to uneven tension during the unloading process.

[0045] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0046] Reference Figures 1 to 10The roll material feeding device according to an embodiment of this application includes a base 100, a mounting base 200, a damping element 300, and an adjustment mechanism.

[0047] Specifically, the mounting base 200 is rotatably mounted on the base 100, and the mounting base 200 is provided with a mounting structure for mounting the roll material. The damping element 300 is movably mounted on the base 100, and the bottom of the mounting base 200 is provided with a rotating shaft 210 rotatably connected to the base 100. The damping element 300 can abut against the rotating shaft 210 to provide frictional force for limiting the rotational speed of the mounting base 200. An adjustment mechanism is provided on the base 100, and the adjustment mechanism is used to adjust the frictional force between the damping element 300 and the rotating shaft 210.

[0048] In use, the roll material is fitted onto the mounting structure. As the material is fed, the tension on the material drives the roll material and the mounting base 200 to rotate synchronously, achieving automatic feeding. During feeding: when the mounting base 200 rotates too fast, the feeding speed of the material exceeds the feeding speed, resulting in insufficient tension on the material. In this case, the friction between the damping element 300 and the rotating shaft 210 can be increased by adjusting the mechanism to reduce the rotation speed of the mounting base 200, thereby reducing the rotation speed of the roll material and increasing the tension on the material. Conversely, when the mounting base 200 rotates too slowly, the feeding speed of the material is less than the feeding speed, resulting in excessive tension on the material. In this case, the friction between the damping element 300 and the rotating shaft 210 can be decreased by adjusting the mechanism to increase the rotation speed of the mounting base 200, thereby increasing the rotation speed of the roll material and reducing the tension on the material. The roll material unloading device of this application can adjust the tension of the material according to the actual situation when unloading the roll material, thereby helping to prevent the material from being deformed or even damaged due to uneven tension during the unloading process.

[0049] Reference Figure 1 and Figure 5In some embodiments, the damping element 300 is an elastic structure, and the adjustment mechanism includes a transmission rod 410 and an unlockable locking structure. The transmission rod 410 is movably mounted on the base 100 and extends toward the rotating shaft 210. One end of the transmission rod 410 near the rotating shaft 210 is connected to the damping element 300, and a handle 411 is provided at the end of the transmission rod 410 away from the rotating shaft 210. The handle 411 is used to drive the transmission rod 410 closer to or away from the rotating shaft 210, and the locking structure is used to restrict the movement of the transmission rod 410 relative to the base 100. When it is necessary to increase the friction between the damping element 300 and the rotating shaft 210, force is applied to the handle 411 to drive the transmission rod 410 closer to the rotating shaft 210, thereby increasing the pressure between the damping element 300 and the rotating shaft 210, and thus increasing the friction between the damping element 300 and the rotating shaft 210. When it is necessary to decrease the friction between the damping element 300 and the rotating shaft 210, force is applied to the handle 411 to drive the transmission rod 410 away from the rotating shaft 210, thereby reducing the pressure between the damping element 300 and the rotating shaft 210, and thus reducing the friction between the damping element 300 and the rotating shaft 210. After the transmission rod 410 is adjusted to the required position, it can be locked by the locking structure. It should be noted that because the damping element 300 is an elastic structure, it can undergo elastic deformation after being subjected to force, thus allowing the transmission rod 410 to be driven closer to or away from the rotating shaft 210 while maintaining contact between the damping element 300 and the rotating shaft 210.

[0050] Reference Figure 2 , Figure 7 and Figure 8In some embodiments, the locking structure includes a first support portion 420 and a limiting portion 430. The first support portion 420 is disposed on the base 100. A first mounting through hole is provided on the first support portion 420 corresponding to the transmission rod 410. The transmission rod 410 is movably inserted into the first mounting through hole. The transmission rod 410 can move relative to the first support portion 420 along its own length direction, and the transmission rod 410 can rotate relative to the first support portion 420 with its own axis as the rotation center line. One end of the transmission rod 410 near the rotating shaft 210 is rotatably connected to the damping member 300. A plurality of limiting portions 430 are provided at intervals along its own length direction on the transmission rod 410. The first support portion 420 is provided with a clearance opening 421 for avoiding the limiting portions 430. When it is necessary to increase the friction between the damping element 300 and the rotating shaft 210, force is applied to the handle 411 to drive the transmission rod 410 to rotate so that the limiting part 430 is aligned with the clearance opening 421. Then, force is applied to the handle 411 to drive the transmission rod 410 closer to the rotating shaft 210, so that at least one limiting part 430 located on the side of the first support part 420 facing away from the rotating shaft 210 passes through the clearance opening 421 and is located on the side of the first support part 420 facing the rotating shaft 210. Then, force is applied to the handle 411 to drive the transmission rod 410 to rotate so that the limiting part 430 is misaligned with the clearance opening 421. At this time, the limiting part 430 located on the side of the first support part 420 facing the rotating shaft 210 can restrict the transmission rod 410 from moving away from the rotating shaft 210, while the limiting part 430 located on the side of the first support part 420 facing away from the rotating shaft 210 can restrict the transmission rod 410 from moving closer to the rotating shaft 210. When it is necessary to reduce the friction between the damping element 300 and the rotating shaft 210, force is applied to the handle 411 to drive the transmission rod 410 to rotate, so that the limiting part 430 is aligned with the clearance opening 421. Then, force is applied to the handle 411 to drive the transmission rod 410 away from the rotating shaft 210, so that at least one limiting part 430 located on the side of the first support part 420 facing the rotating shaft 210 passes through the clearance opening 421 and is located on the side of the first support part 420 away from the rotating shaft 210. Then, force is applied to the handle 411 to drive the transmission rod 410 to rotate, so that the limiting part 430 is misaligned with the clearance opening 421. At this time, the limiting part 430 located on the side of the first support part 420 facing the rotating shaft 210 can restrict the transmission rod 410 from moving away from the rotating shaft 210, while the limiting part 430 located on the side of the first support part 420 away from the rotating shaft 210 can restrict the transmission rod 410 from approaching the rotating shaft 210.

[0051] Specifically, refer to Figure 3 and Figure 4The damping component 300 is provided with a mounting part 310 corresponding to the transmission rod 410. The mounting part 310 is provided with a plug groove. The end of the transmission rod 410 is inserted into the plug groove. The side of the mounting part 310 is provided with a clearance hole 311 communicating with the plug groove. The clearance hole 311 is arc-shaped and extends along the circumference of the mounting part 310. The transmission rod 410 is provided with an anti-detachment part 412 passing through the clearance hole 311. When the transmission rod 410 rotates, the anti-detachment part 412 slides in the clearance hole 311. The anti-detachment part 412 can prevent the transmission rod 410 from disengaging from the plug groove.

[0052] Specifically, the anti-detachment part 412 can be a bolt threaded to the transmission rod 410, or it can be a pin inserted into the transmission rod 410.

[0053] It should be noted that in some other embodiments, the transmission rod 410 may also be connected to the damping member 300 via a ball joint structure.

[0054] Reference Figure 1 and Figure 5 In some embodiments, the handle 411 and the transmission rod 410 are arranged at an angle to facilitate the application of force to drive the transmission rod 410 to move or rotate.

[0055] Reference Figure 3 In some embodiments, the locking structure further includes a second support portion 440 and a first compression spring 450. The second support portion 440 is disposed on the base 100. A second mounting through hole is provided on the second support portion 440 corresponding to the transmission rod 410. The transmission rod 410 is movably inserted into the second mounting through hole. The transmission rod 410 can move relative to the second support portion 440 along its own length direction, and the transmission rod 410 can rotate relative to the second support portion 440 about its own axis as the rotation center line. An abutment portion 413 is provided on the transmission rod 410. The abutment portion 413 is located on the side of the second support portion 440 opposite to the rotating shaft 210. The first compression spring 450 is sleeved on the transmission rod 410. One end of the first compression spring 450 abuts against the second support portion 440, and the other end of the first compression spring 450 abuts against the abutment portion 413. On the one hand, the first compression spring 450 can cause the limiting part 430 located on the side of the first support part 420 facing the rotating shaft 210 to abut against the first support part 420, thereby helping to limit the transmission rod 410 from rotating due to collision or vibration and to release the locking structure. On the other hand, when driving the transmission rod 410 away from the rotating shaft 210, the elastic force provided by the first compression spring 450 can play an auxiliary role.

[0056] It should be noted that in some other embodiments, the adjustment mechanism can be replaced by a cylinder, hydraulic cylinder, or other drive structure capable of driving the target component to reciprocate in a straight line. Specifically, the pressure between the damping element 300 and the rotating shaft 210 is adjusted by changing the magnitude of the driving force provided by the drive structure, thereby adjusting the friction between the damping element 300 and the rotating shaft 210. In this case, the damping element 300 may not use an elastic structure, and the aforementioned locking structure is also unnecessary.

[0057] In some embodiments, the mounting structure is configured to accommodate different inner diameters of the roll material, thereby making the roll material feeding device of this application suitable for roll materials of different specifications.

[0058] Reference Figure 1 and Figure 5 In some embodiments, the mounting structure includes a central column 510 and multiple vertical rods 520 arranged in a ring array around the axis of the rotating shaft 210. The central column 510 is located on the top of the mounting base 200, and the axis of the central column 510 is collinear with the axis of the rotating shaft 210. The vertical rods 520 are slidably mounted on the mounting base 200 and can move closer to or further away from the central column 510. A connecting tube 530 is provided on the central column 510 corresponding to each vertical rod 520. A connecting part 521 is provided on the vertical rod 520 and is movably inserted into the corresponding connecting tube 530. A second compression spring 540 is provided in each connecting tube 530. The second compression spring 540 acts on the corresponding connecting part 521 and is used to drive the corresponding vertical rod 520 away from the central column 510. In use, force is applied to bring the vertical rods 520 together, then the roll material is fitted onto the mounting structure. The force applied to the vertical rods 520 is then removed, causing them to move apart under the influence of the second compression spring 540, thus adapting to the inner diameter of the roll material. The second compression spring 540 not only enables the vertical rods 520 to adapt to the inner diameter of the roll material, reducing adjustment time, but also provides elastic force to hold the vertical rods 520 against the inner side of the roll material, thereby helping to prevent the roll material from vertically detaching from the mounting structure during unloading.

[0059] Specifically, refer to Figure 6 The mounting base 200 is provided with a groove 220 corresponding to the vertical rod 520, and the vertical rod 520 is slidably disposed in the groove 220. The length of the groove 220 can limit the extreme position of the vertical rod 520, thereby preventing the connecting part 521 from disengaging from the connecting pipe 530.

[0060] An anti-detachment structure can be provided between the vertical rod 520 and the slide rail 220. This anti-detachment structure is used to prevent the vertical rod 520 from vertically detaching from the slide rail 220. The anti-detachment structure can be referenced from drawer slides.

[0061] It should be noted that in some other embodiments, the aforementioned groove 220 can also be replaced with a guide rail, and the vertical rod 520 is slidably connected to the guide rail. The specific connection structure can be referred to as a linear guide rail.

[0062] It should be noted that in some other embodiments, multiple installation positions can be set on the mounting base 200 corresponding to each vertical rod 520, and the vertical rod 520 can be installed by fasteners. When in use, the installation position of the vertical rod 520 can be changed to adapt to different specifications of roll material.

[0063] Reference Figure 9 and Figure 10 In some embodiments, the mounting structure further includes a drive structure for driving the vertical rods 520 together. The drive structure includes a pressing rod 610 and a rope 620. The central column 510 is a hollow tubular structure with an open top. The pressing rod 610 is movably inserted into the central column 510. Each connecting tube 530 contains a rope 620. One end of the rope 620 is connected to a corresponding connecting part 521, and the other end extends into the central column 510 and is connected to the pressing rod 610. When the pressing rod 610 is pressed, it can drive the vertical rods 520 together via the rope 620. In use, only the pressing rod 610 needs to be pressed to drive the vertical rods 520 together, without needing to apply force to each vertical rod 520 simultaneously, thus reducing the difficulty of operation.

[0064] Specifically, refer to Figure 10 The central column 510 is provided with mounting holes 511 for threading ropes 620.

[0065] In some embodiments, the pressing rod 610 and the central column 510 are provided with an unlockable positioning structure. When the pressing rod 610 drives the vertical rod 520 to move closer together to the extreme position, the positioning structure can restrict the pressing rod 610 from moving upward relative to the central column 510, thereby positioning the vertical rod 520 at the extreme position of moving closer together. It is not necessary to always apply force to the pressing rod 610 to keep the pressing rod 610 in the downward position, which helps to reduce the difficulty of operation.

[0066] Reference Figure 9 and Figure 10In some embodiments, the positioning structure includes a positioning part (not shown) and a positioning hole 512. The positioning part is floatingly mounted on the pressing rod 610 and can be housed inside the pressing rod 610. An elastic element is provided between the positioning part and the pressing rod 610 to drive the positioning part to extend. A positioning hole 512 is provided on the central column 510 corresponding to the positioning part. When the pressing rod 610 drives the vertical rod 520 to their extreme positions, the positioning part and the positioning hole 512 are aligned. The positioning part is driven into the positioning hole 512 by the elastic element. When unlocking is required, the positioning part is pressed to disengage it from the positioning hole 512 and house it inside the pressing rod 610, while the pressing rod 610 is driven upward. Specifically, the positioning part is similar to the elastic pressing structure provided on the main rib of an umbrella for locking the umbrella in a folded state.

[0067] It should be noted that in some other embodiments, the positioning structure may also be positioned by using detachable pins in conjunction with pin holes provided on the pressing rod 610 and the central column 510.

[0068] Reference Figure 1 , Figure 5 and Figure 9 In some embodiments, the upper end of the vertical rod 520 is provided with a guide portion 522 that bends toward the rotating shaft 210. The guide portion 522 has a guiding function and helps to reduce the alignment requirements between the roll and the installation structure when the roll is installed, so as to facilitate the installation of the roll.

[0069] Reference Figure 1 and Figure 5 In some embodiments, the roll material unloading device further includes a ring-shaped guardrail structure disposed at the edge of the mounting base 200. The guardrail structure includes a protective ring 710 and a plurality of support rods 720 spaced apart along the edge of the mounting base 200, with the protective ring 710 disposed on the top of the support rods 720. In use, the guardrail structure can work with the mounting structure to limit the roll material, thereby improving the stability and reliability of the unloading process. At the same time, the protective ring 710 can support the material being fed.
