Description

Technical Field

[0001] The invention relates to the technical field of cloth roll strip feeding, and in particular to an adaptive stretching device for cloth roll processing. Background Art

[0002] In the prior art, when cutting or performing other related processing on fabrics, it is necessary to place the fabric roll on a roller device, and then connect one end of the fabric roll on the roller device to a processing device such as a cutting device. This method is relatively traditional, convenient and efficient, and is still applicable to modern production equipment. However, with the continuous iteration of modern textile technology, fabrics are gradually subdivided. When it is necessary to transport loose fabrics such as gauze and needle-punched fabrics, if the roller device and the processing device are too tight, the processed fabric is prone to excessive stretching during transmission, resulting in inaccurate cutting and deformation. If the roller device and the processing device are too loose, the processing equipment is prone to uneven feeding, fabric folding and jamming, etc.

[0003] Currently, there is no low-cost solution in the existing disclosed technologies that can overcome the above problems. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an adaptive stretching device for cloth roll processing, which has a simple structure, low cost and can automatically adjust the tension of the cloth between the two ends of the rolling roller device and the processing device.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: an adaptive stretching device for cloth roll processing, which includes a rolling curtain, the rolling curtain includes a plurality of first lightweight plate bodies rotatably connected to each other, rotating ears are provided at both ends of the upper part of the first lightweight plate body, and a rotating protrusion is provided at the lower part of the first lightweight plate body. Two adjacent first lightweight plate bodies are rotatably connected through the rotating ears and the rotating protrusions, a fixing wire ring is provided on one side of the first lightweight plate body, and elastic ropes are provided between the fixing wire rings. An elastic tri-fold plate is rotatably connected to the first lightweight plate body at the uppermost end, and two parallel fixed frames are provided on the top of the elastic tri-fold plate, a movable mobile base is provided on the fixed frame, and a fixture for fixing the device on a matching device is provided on the mobile base.

[0006] As an improvement, the bottom of the first lightweight plate body at the lowest end is rotatably connected to a second lightweight plate body, and the bottom of the second lightweight plate body is rotatably connected to a first sliding roller.

[0007] As an improvement, the elastic rope passes through a plurality of the wire fixing rings, and limit buckles are provided at both upper and lower ends of the elastic rope, and both ends of the elastic rope pass through the limit buckles.

[0008] As an improvement, the elastic three-fold plate includes a first folding plate rotatably connected to the first lightweight plate body at the top, a second folding plate rotatably connected to the end of the first folding plate away from the first lightweight plate body, and a third folding plate rotatably connected to the end of the second folding plate away from the first folding plate. The first folding plate, the second folding plate and the third folding plate are Z-shaped, a first spring is provided between the first folding plate and the second folding plate, and a first spring is provided between the second folding plate and the third folding plate.

[0009] As an improvement, the fixing frame includes a mounting plate detachably mounted to the third folding plate, and two rail bodies mounted in parallel are arranged on the mounting plate, and a tooth plate is arranged on the rail body.

[0010] As an improvement, the movable base includes a sliding seat slidably connected to the rail body, the top of the sliding seat is fixedly connected to the fixer, the sliding seat is provided with a limiting shell located on the back side of the fixer, the sliding seat is provided with a T-shaped slide groove matching the rail body and the tooth plate, the limiting shell is provided with a limiting slide cavity communicating with the T-shaped slide groove, the limiting slide cavity is provided with a limiting clamping plate that can move up and down, a second spring is provided between the top of the limiting clamping plate and the top inner wall of the limiting shell, the top of the limiting clamping plate is provided with a pull rod passing through the limiting shell, and the pull rod is sleeved with the spring.

[0011] As an improvement, the fixture includes a heightening frame fixedly mounted on a sliding seat, a hollow semi-annular clamp being provided on the heightening frame, a plurality of fan-shaped strip grooves being provided on both sides of the hollow semi-annular clamp, a plurality of second sliding rollers corresponding to the strip grooves being provided on the open side of the hollow semi-annular clamp, sliding shafts being provided at both ends of the second sliding rollers, and the sliding shafts being movable and rotatable in the strip grooves.

[0012] As an improvement, the inner wall of the hollow semi-annular fixture is provided with a plurality of third springs corresponding to the second sliding rollers, and the third springs are fixedly connected with arc-shaped sliding plates in sliding contact with the second sliding rollers.

[0013] After adopting the above structure, the present invention has the following advantages:

[0014] 1. The first light plates of the device are rotatably connected to each other. Under the influence of gravity and the length of the rolling curtain itself, the first sliding roller or the first light plate located below contacts the cloth, so that the originally loose cloth strips are relatively tight. In addition, since the first light plates are rotatably connected to each other, the cloth strips will not be overly tight, so that the cloth strips will not be stretched and deformed due to excessive tension, and will not be overly loose due to the different transmission rates at both ends of the roller device and the processing device.

[0015] 2. Installing elastic ropes between the first light-weight plates can enhance stability and effectively prevent the cloth strips from being unable to return to their original positions due to the large elastic force when the cloth strips suddenly become tight from being loose during transportation;

[0016] 3. When the fabric suddenly goes from loose to tight during the transmission process, the elastic force of the fabric strip will cause the first sliding roller end of the rolling curtain to rise rapidly. This elastic force is relatively large at the moment. The first folding plate, the second folding plate and the third folding plate are in a Z shape, and part of the elastic force can be released between the first folding plate, the second folding plate and the third folding plate. The elastic force is gradually consumed through the vibration of the first spring, and it helps the rolling curtain to return to its original position.

[0017] 4. The two symmetrical hollow semi-circular clamps are moved to the outside of the two beams of the connecting frame between the rolling device and the processing device. Since some of the integrated devices share the same drive system, some of the beams are also transmission shafts, so that the open ends of the hollow semi-circular clamps are in close contact with the beams, thereby achieving fixation of both ends. The third spring provides pre-tension so that the second sliding roller always wraps the beams or transmission shafts of different diameters, and when the transmission shaft rotates, the sliding contact between the second sliding roller and the arc-shaped sliding sheet can make the second sliding roller rotate with the transmission shaft, which does not affect the transmission system of the rolling device and the processing device while being fixed.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 :

[0031] A self-adaptive stretching device for cloth roll processing, comprising a rolling curtain 1, the rolling curtain 1 comprising a plurality of first light-weight plates 101 rotatably connected to each other, two ends of the upper part of the first light-weight plates 101 are provided with rotating ears 102, the lower part of the first light-weight plates 101 is provided with a rotating protrusion 103, two adjacent first light-weight plates 101 are rotatably connected through the rotating ears 102 and the rotating protrusion 103, a fixed wire ring 106 is provided on one side of the first light-weight plates 101, elastic ropes 107 are provided between the fixed wire rings 106, the bottom of the first light-weight plates 101 at the lowermost end is rotatably connected to a second light-weight plate 104, and the bottom of the second light-weight plate 104 is rotatably connected to a first sliding roller 105;

[0032] The elastic rope 107 passes through the plurality of wire fixing rings 106 . Limit buckles 108 are provided at both upper and lower ends of the elastic rope 107 . Both ends of the elastic rope 107 pass through the limit buckles 108 .

[0033] Through the above structure, the cloth strip between the roller device and the processing device passes through the bottom of the first sliding roller 105, and the tension of the cloth strip between the roller device and the processing device can always be kept in a relatively loose state. Since the first light-weight plates 101 are rotatably connected to each other, under the influence of gravity and the length of the roller blind 1 itself, the first sliding roller 105 or the first light-weight plate 101 located below contacts the cloth, so that the originally loose cloth strip is relatively tight, and since the first light-weight plates 101 are rotatably connected to each other, the cloth strip will not be overly tight, which makes the cloth strip present a state that will not be stretched and deformed due to excessive tension, and will not be overly loose due to the different transmission rates at both ends of the roller device and the processing device;

[0034] Since the cloth strips between the roller device and the processing device are transmitted from the roller device to the processing device, it is expected that the whole composed of several first lightweight panels 101 can be bent toward the direction of the processing device, so as to enhance stability and prevent the cloth strips from suddenly changing from loose to tight during transportation. The elastic force of the cloth will cause the whole composed of several first lightweight panels 101 to bounce upward and be unable to return to its original position quickly. Therefore, elastic ropes 107 are installed between several first lightweight panels 101 so that the whole composed of several first lightweight panels 101 can have an initial shape and be easy to return to its original position.

[0035] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 6 :

[0036] An elastic three-fold plate 3 is rotatably connected to the first lightweight plate body 101 at the top, and the elastic three-fold plate 3 includes a first folding plate 301 rotatably connected to the first lightweight plate body 101 at the top, an end of the first folding plate 301 away from the first lightweight plate body 101 is rotatably connected to a second folding plate 303, and an end of the second folding plate 303 away from the first folding plate 301 is rotatably connected to a third folding plate 304, the first folding plate 301, the second folding plate 303 and the third folding plate 304 are in a Z shape, a first spring 302 is provided between the first folding plate 301 and the second folding plate 303, and a first spring 302 is provided between the second folding plate 303 and the third folding plate 304.

[0037] When the cloth is being transmitted and suddenly becomes taut from loose, the elastic force of the cloth strip will cause the first sliding roller 105 end of the rolling curtain 1 to rise rapidly. This elastic force is relatively large in an instant. Through the above structure, the first folding plate 301, the second folding plate 303 and the third folding plate 304 are in a Z shape, and a part of the elastic force can be released between the first folding plate 301, the second folding plate 303 and the third folding plate 304. The elastic force is gradually consumed through the vibration of the first spring 302, and it helps the rolling curtain 1 to return to its original position.

[0038] Combined with Figure 6, Attachment Figure 7 , Attachment Figure 8 and attached Fig.10 :

[0039] Two parallel mounted fixing frames 5 are provided on the top of the elastic three-fold plate 3, and the fixing frames 5 include a mounting plate 501 detachably mounted with the third fold plate 304, and two parallel mounted rail bodies 502 are provided on the mounting plate 501, and a tooth plate 503 is provided on the rail body 502;

[0040] A movable mobile base 6 is provided on the fixed frame 5, and the mobile base 6 includes a sliding seat 601 slidably connected to the rail body 502, and the top of the sliding seat 601 is fixedly connected to the fixer 7. A limiting shell 607 located on the back side of the fixer 7 is provided on the sliding seat 601, and a T-shaped slide groove 602 matching the rail body 502 and the tooth plate 503 is provided in the sliding seat 601, and a limiting slide cavity 603 communicating with the T-shaped slide groove 602 is provided in the limiting shell 607, and a limiting card plate 604 movable up and down is provided in the limiting slide cavity 603, and a second spring 605 is provided between the top of the limiting card plate 604 and the inner wall of the top of the limiting shell 607, and a pull rod 606 penetrating the limiting shell 607 is provided at the top of the limiting card plate 604, and the pull rod 606 is sleeved with the second spring 605;

[0041] Since the spacing between the crossbeams of the connecting frames between different rolling roller devices and processing devices is different, through this structure, the pull rod 606 is pulled upward so that the limiting clamp 604 at the lower end of the pull rod 606 does not contact the tooth plate 503. At this time, the position of the sliding seat 601 can be adjusted, and the pull rod 606 is released. The second spring 605 provides pre-tension so that the limiting clamp 604 at the lower end of the pull rod 606 is clamped with the tooth plate 503, and the adjustable sliding seat 601 can be positioned.

[0042] Combined with Figure 7 , Attachment Figure 8 and attached Fig. 9 :

[0043] The movable base 6 is provided with a fixture 7 for fixing the device on the matching device, and the fixture 7 includes a heightening frame 701 fixedly mounted on the sliding seat 601, and a hollow semi-annular clamp 702 is provided on the heightening frame 701, and a plurality of fan-shaped strip-shaped through grooves 703 are provided on both sides of the hollow semi-annular clamp 702, and a plurality of second sliding rollers 704 corresponding to the strip-shaped through grooves 703 are provided on the opening side of the hollow semi-annular clamp 702, and sliding shafts 705 are provided at both ends of the second sliding rollers 704, and the sliding shafts 705 can move and rotate in the strip-shaped through grooves 703;

[0044] The inner wall of the hollow semi-annular fixture 702 is provided with a plurality of third springs 706 corresponding to the second sliding rollers 704 , and the third springs 706 are fixedly connected with arc-shaped sliding sheets 707 that are in sliding contact with the second sliding rollers 704 .

[0045] A connecting frame is usually set between the roller device and the processing device to fix and position the roller device and the processing device at both ends, so that the cloth strip output end of the roller device can be kept consistent with the cloth strip input end of the processing device, and a number of parallel beams are set between the top frames of the connecting frame to ensure that the connecting frame maintains its shape. In addition, some devices in which the roller device and the processing device are integrated, that is, all-in-one machines, in order to synchronize the output end and the input end, the roller device and the processing device will use the same set of rotation drive system. Therefore, this kind of all-in-one machine will replace the beam with a transmission shaft, which is used to maintain the shape of the connecting frame on the one hand, and to transmit the rotation of the two ends through the gear assembly on the other hand. The beam or transmission shaft is connected to the mounting plate 501 Parallel, through this structure, two beams with appropriate positions are selected, and the two symmetrical hollow semi-circular clamps 702 are respectively moved to the left side of the left beam and the right side of the right beam, which can not only fix the device but also prevent the device as a whole from being folded by external force. When fixed on the transmission shaft of the all-in-one machine, the open end of the hollow semi-circular clamp 702 is in close contact with the transmission shaft, and the two ends are fixed. Due to the pre-tension provided by the third spring 706, the second sliding roller 704 always wraps the beams or transmission shafts of different diameters, and when the transmission shaft rotates, the sliding contact between the second sliding roller 704 and the arc-shaped sliding sheet 707 can make the second sliding roller 704 rotate with the transmission shaft, thereby fixing the device without affecting the operation of the transmission system of the all-in-one machine.

[0046] In the specific implementation of the present invention, the pull rod 606 is pulled to move the sliding seat 601 to a position on the rail body 502, so that the two symmetrical hollow semi-circular clamps 702 are moved to the outside of the two beams of the connecting frame between the roller device and the processing device, so that the open ends of the hollow semi-circular clamps 702 are in close contact with the beams, and the pull rod 606 is released to fix the position, and at the same time, the whole composed of the first lightweight plate body 101 is bent toward the transmission direction of the cloth strip;

[0047] The cloth strip between the roller device and the processing device passes through the bottom of the first sliding roller 105, and the tension of the cloth strip between the roller device and the processing device can always be kept in a relatively loose state. Since the first light-weight plates 101 are rotatably connected to each other, under the influence of gravity and the length of the roller blind 1 itself, the first sliding roller 105 or the first light-weight plate 101 located below contacts the cloth, so that the originally loose cloth strip is relatively tight, and since the first light-weight plates 101 are rotatably connected to each other, the cloth strip will not be overly tight, so that the cloth strip will present a state that will not be stretched and deformed due to excessive tension, and will not be overly loose due to the different transmission rates at both ends of the roller device and the processing device;

[0048] When the cloth is being transmitted and suddenly becomes taut from loose, the elastic force of the cloth strip will cause the first sliding roller 105 end of the rolling curtain 1 to rise rapidly. This elastic force is relatively large in an instant. Through the above structure, the first folding plate 301, the second folding plate 303 and the third folding plate 304 are in a Z shape, and a part of the elastic force can be released between the first folding plate 301, the second folding plate 303 and the third folding plate 304. The elastic force is gradually consumed through the vibration of the first spring 302, and it helps the rolling curtain 1 to return to its original position.

[0049] The present invention and its implementation methods are described above, and such description is not restrictive, and the actual structure is not limited thereto. In general, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can creatively design a structure and implementation method similar to the technical solution, which should fall within the protection scope of the present invention.
