Description

Technical Field

[0001] This application relates to the field of winding, and more particularly to a winding support device and winding equipment for roll materials. Background Technology

[0002] Wide-format printing technology, due to its ability to efficiently output large-format images, is increasingly widely used in advertising, decoration, and graphic design. In the wide-format printing production process, the printed media (such as paper and fabric) needs to be neatly and undamagedly rolled up for subsequent storage, transportation, or processing. The quality of the winding, especially the flatness of the small rolls formed in the initial stage of winding, directly affects the quality of the final product and subsequent processes. Currently, the winding process of wide-format printing equipment faces a significant technical bottleneck. Due to the large printing area, the winding rod (or winding shaft) supporting the printing media must have a corresponding length. Under the influence of its own weight and winding tension, this large-span winding rod inevitably bends and sags in the middle. This problem is particularly prominent in the early stages of winding, when the winding diameter is still small (i.e., forming a "small roll"). At this time, the effective support length of the winding rod is the longest, its rigidity is the weakest, and the sagging deformation is the most obvious.

[0003] The significant downward vertical contact of the take-up bar causes its support function to fail. The printing media located in the middle area of ​​the take-up bar, lacking sufficient rigid support below, loses horizontal tension and consequently sags downwards. This non-horizontal, sunken media state prevents the media from being layered and wound evenly on the core during continuous winding. The direct consequence is uneven stress and interlayer slippage within the finished media roll, forming persistent longitudinal wrinkles on the media surface. These wrinkles not only severely affect the appearance quality of the finished product but may also cause secondary problems such as media tearing and image misalignment during subsequent flattening or lamination processes. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a roll winding support device and winding equipment.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A coil winding support device, having a first direction, includes: The mounting bracket has a receiving space, and the receiving space has an inclined guide groove on its side wall along the first direction; A winding rack, wherein the winding rack is disposed within the accommodating space; A take-up shaft, which is rotatably mounted on the take-up frame; A support shaft, the two ends of which are slidably disposed in the guide groove.

[0006] Furthermore, the winding frame includes two spaced-apart plates, with a first rod and a second rod spaced apart between the two plates, and the two ends of the winding shaft are respectively connected to the plates.

[0007] Furthermore, a fixing plate is fixedly installed on both sides of the accommodating space along the first direction, and the fixing plate is opened on the side walls of the two guide grooves that are close to each other.

[0008] Furthermore, a first roller is provided at the end of the support shaft, and the first roller is rotatably disposed in the guide groove.

[0009] Furthermore, a rack is provided on the side of the guide groove away from the side wall of the mounting bracket, and a gear is provided at the end of the support shaft, the gear meshing with the rack.

[0010] Furthermore, the rack includes a connecting strip fixedly disposed on the fixed plate, and the connecting strip has multiple teeth on its side wall facing the gear.

[0011] Furthermore, the support shaft includes a first shaft body, and a second shaft body is disposed on the circumferential surface of the first shaft body.

[0012] Furthermore, a blocking component is provided on one side of the accommodating space along the first direction, and the blocking component is located on the guide path of the guide groove; The blocking assembly includes a linear drive member with a drive rod. A fixed seat is fixedly disposed on the side of the linear drive member facing the guide groove. A first mounting groove is provided on the fixed seat. A mounting shaft is disposed in the first mounting groove. A stop is rotatably disposed on the mounting shaft. An avoidance hole is provided through the fixed seat at the position of the drive rod. The drive rod passes through the avoidance hole and abuts against the stop.

[0013] Furthermore, a second mounting groove is provided on the stop block, and a second roller is rotatably disposed in the second mounting groove.

[0014] This application also provides a winding device, which includes the winding support device described in any one of the above-described methods.

[0015] This application utilizes a support shaft whose two ends are slidably mounted in inclined guide grooves on the side wall of the mounting frame. Under the action of gravity, the support shaft automatically slides along the guide grooves and abuts against the circumference of the take-up shaft, providing rigid support for the printing media forming small rolls in the initial stage of take-up. This effectively overcomes the problem of sagging in the middle of the take-up shaft due to its large span. The support shaft directly supports the media in the sagging area, eliminating media slack and drooping, ensuring that the media maintains horizontal tension during take-up and is layered and wound on the core in a flat and uniform manner, thus solving the problem of longitudinal wrinkles in the media caused by the sagging of the take-up shaft.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0025] This application provides a roll winding support device. The device includes a first direction, a mounting frame 100, a winding frame 200, a winding shaft 300, and a support shaft 400. The mounting frame 100 has an accommodating space, and an inclined guide groove 101 is formed on the side wall of the accommodating space along the first direction. The winding frame 200 is disposed in the accommodating space, and the winding shaft 300 is rotatably disposed on the winding frame 200. The two ends of the support shaft 400 are slidably disposed in the guide groove 101.

[0026] In this embodiment, the first direction mentioned above is the lateral direction, and the product to be rolled up is printing paper. The following description uses printing paper as an example.

[0027] See Figure 1 and Figure 2 As shown, the mounting frame 100 consists of two spaced-apart uprights and a connecting rod for connecting the two. An accommodating space is formed between the two uprights. The winding frame 200 is located in the accommodating space, and the winding shaft 300 is rotatably mounted on the winding frame 200. Since the winding shaft 300 has a large span in the lateral direction, its middle part may bend under its own weight. As a result, when winding, the printing paper cannot adhere to the circumference of the winding shaft 300 and also bends downward, thus causing winding wrinkles.

[0028] In this embodiment, the diameter of the support shaft 400 should be larger than that of the take-up shaft 300, so that the support shaft 400 will not bend in the middle part under this span. Under the action of the inclined guide groove 101, in the initial state, the support shaft 400 slides down along the guide groove 101 under the action of gravity until its circumferential surface abuts against the circumferential surface of the take-up shaft 300. This can provide good support for the printing paper that is about to be rolled up, prevent it from bending downward at the position of the take-up shaft 300 and causing wrinkles during winding, and to a certain extent correct the take-up shaft 300 during the rotation process, further preventing wrinkles from appearing when the printing paper is wound up.

[0029] Furthermore, as the take-up shaft 300 winds the printing paper to form a paper roll, the diameter of the paper roll increases, which drives the support shaft 400 to move along the guide groove 101 in a direction away from the take-up shaft 300. That is, throughout the entire winding process, the support shaft 400 is always in contact with the circumference of the paper roll and supports the printing paper.

[0030] This embodiment should also include a corresponding rotary drive (not shown in the figure) to drive the take-up shaft 300 to rotate. For example, the rotary drive can be a motor or other components.

[0031] like Figure 1 and Figure 2 As shown, the tilt angle of the guide groove 101 should ensure that the support shaft 400 moves toward the winding shaft 300 under the action of gravity. The specific tilt angle is not limited and can be designed according to actual needs.

[0032] In some embodiments, the winding frame 200 includes two spaced plates 210, with a first rod 220 and a second rod 230 spaced apart between the two plates 210, and the two ends of the winding shaft 300 are respectively connected to the plates 210.

[0033] Please continue reading. Figure 2 As shown, the two plates 210 are spaced apart and connected by the first rod 220 and the second rod 230 to form a stable frame. The winding frame 200 can also be fixedly or rotatably connected to the mounting frame 100. In practice, the design can be customized as needed.

[0034] In some embodiments, a fixing plate 110 is fixedly provided on both side walls of the accommodating space along the first direction, and the fixing plate 110 is provided on the side walls of the two guide grooves 101 that are close to each other.

[0035] like Figure 2 and Figure 6 As shown, since the upright plate of the mounting bracket 100 is relatively large, it would be difficult to open the guide groove 101 on the upright plate. In order to reduce the processing difficulty of the guide groove 101, a fixing plate 110 with the guide groove 101 can be fixedly connected to the side wall of each upright plate near the accommodating space by bolts. That is, it is only necessary to process the guide groove 101 separately on the fixing plate 110, and then fix the fixing plate 110 in the preset position of the upright plate. The operation is simple and the processing difficulty of the guide groove 101 is significantly reduced.

[0036] In some embodiments, a first roller 401 is provided at the end of the support shaft 400, and the first roller 401 is rotatably disposed in the guide groove 101.

[0037] Please see Figure 3 , Figure 4 as well as Figure 5 As shown, in order to enable the support shaft 400 to move smoothly along the guide groove 101, first rollers 401 are installed at both ends of the support shaft 400 to reduce the friction between the support shaft 400 and the inner wall of the guide groove 101, thereby improving the smoothness of movement.

[0038] In this embodiment, the first roller 401 can be a bearing.

[0039] In some embodiments, a rack 111 is provided on the side of the guide groove 101 away from the side wall of the mounting bracket 100, and a gear 402 is provided at the end of the support shaft 400, the gear 402 meshing with the rack 111.

[0040] Please continue reading. Figure 3 and Figure 4 As shown, in order to make the support shaft 400 move more stably along the guide groove 101, gears 402 are installed at both ends of the support shaft 400, and a rack 111 that meshes with the gears 402 is fixedly installed on the side of the fixed plate 110 away from the vertical plate. The cooperation between the gears 402 and the rack 111 makes the movement of the support shaft 400 more stable.

[0041] In some embodiments, the rack 111 includes a connecting strip 1111 fixedly disposed on the fixing plate 110, and the connecting strip 1111 has a plurality of teeth 1112 on its sidewall facing the gear 402.

[0042] See Figure 3 , Figure 4 as well as Figure 7 As shown, if the corresponding teeth 1112 are opened on the inner wall of the guide groove 101, the processing difficulty is relatively large. The connecting strip 1111 is a plate. First, the teeth 1112 are opened on the side of the connecting strip 1111 facing the gear 402. Then, the connecting strip 1111 with the teeth 1112 is installed on the fixing plate 110 by bolts.

[0043] For example, multiple elongated through slots can be made on the connecting strip 1111, and then each bolt can be passed through the elongated through slots to fasten the connecting strip 1111 to the fixing plate 110 to complete the installation. This split method greatly reduces the processing difficulty of the teeth 1112 and reduces the production cost.

[0044] In some embodiments, the support shaft 400 includes a first shaft body 410, and a second shaft body 420 is disposed on the circumferential surface of the first shaft body 410.

[0045] Please see Figures 3 to 5As shown, the second shaft 420 is disposed on the outer peripheral surface of the first shaft 410. The length of the first shaft 410 should be longer than that of the second shaft 420. The first roller 401 and the gear 402 are both installed at the end of the first shaft 410. The second shaft 420 contacts the printing paper and supports the printing paper.

[0046] In some embodiments, a blocking component 500 is provided on one side of the accommodating space along a first direction. The blocking component 500 is located on the guide path of the guide groove 101. The blocking component 500 includes a linear drive member 510. The linear drive member 510 has a telescopic drive rod. A fixing seat 520 is fixedly provided on the linear drive member 510 toward the guide groove 101. A first mounting groove 5201 is provided on the fixing seat 520. A mounting shaft 521 is provided in the first mounting groove 5201. A stop 530 is rotatably provided on the mounting shaft 521. An avoidance hole 5202 is provided through the fixing seat 520 at the position of the drive rod. The drive rod passes through the avoidance hole 5202 and abuts against the stop 530.

[0047] In this embodiment, the linear drive 510 is a cylinder.

[0048] Please see Figure 8 and Figure 9 As shown, after the take-up shaft 300 winds the printing paper to a certain diameter, the paper roll needs to be removed from the take-up shaft 300. Since the paper roll no longer provides a driving force away from the take-up shaft 300 to the support shaft 400, the support shaft 400 will move towards the take-up shaft 300 under the action of gravity when removing the paper roll. In order to prevent the support shaft 400 from affecting the removal of the paper roll, a blocking component 500 is set on the path of the guide groove 101. When the support shaft 400 passes the blocking component 500, it will be blocked by the blocking component 500 to prevent the support shaft 400 from moving towards the take-up shaft 300.

[0049] Please continue reading. Figure 8 and Figure 9 In the initial state shown, the linear drive 510 retracts, causing the drive rod to disengage from the clearance hole 5202. At this time, the drive will not abut against the stop block 530. The end of the stop block 530 will rest on the abutment block 540, that is, the abutment block 540 supports the stop block 530. A coil spring 522 is provided on the circumference of the mounting shaft 521. One end of the coil spring 522 abuts against the inner bottom wall of the first mounting groove 5201, and the other end of the coil spring 522 abuts against the stop block 530. Here, the function of the coil spring 522 is to drive the stop block 530 to always be in contact with the surface of the abutment block 540. That is, at this time, the stop block 530 plays the role of allowing the support shaft 400 to pass in one direction, and then blocking in the reverse direction.

[0050] Specifically, when the support shaft 400 passes the stop 530, the first shaft 410 of the support shaft 400 will abut against the stop 530, causing it to overcome the elastic force of the coil spring 522 and rotate a certain angle about the mounting shaft 521, so that the support shaft 400 is positioned diagonally above the stop 530. When the printing paper needs to be removed after being wound to a certain diameter, the paper roll no longer exerts an upward force on the support shaft 400. Therefore, under the blocking action of the stop 530, it will not move along the guide groove 101 to the bottom, thus not affecting the removal of the paper roll.

[0051] Furthermore, when it is necessary to rewind the printing paper via the take-up shaft 300, the linear drive 510 can drive its drive rod through the clearance hole 5202 to rotate the stop 530 by a certain angle. At this time, the first shaft 410 of the support shaft 400 is no longer blocked by the stop 530. Under the action of gravity, the support shaft 400 will slide to the bottom and re-abut against the circumference of the take-up shaft 300, thus supporting the printing paper again.

[0052] In some embodiments, a second mounting groove 531 is provided on the stop block 530, and a second roller 532 is rotatably disposed in the second mounting groove 531.

[0053] Please continue reading. Figure 8 and Figure 9 As shown, in order to make the first shaft 410 of the support shaft 400 pass through the stop 530 more smoothly, a second roller 532 is rotatably installed in the second mounting groove 531 of the stop 530. When the first shaft 410 passes through the stop 530, the sliding friction with the stop 530 is changed to the rolling friction with the second roller 532, thereby reducing the wear on the surface of the stop 530 and the circumferential surface of the first shaft 410.
