Description

Technical Field

[0001] This invention relates to the technical field of release paper production, and more particularly to an unwinding mechanism and a release paper slitting machine. Background Technology

[0002] Release paper is a type of anti-stick paper that prevents prepreg from sticking together and protects the prepreg from contamination.

[0003] During the production process, in order to facilitate transportation or process the release paper into a predetermined size, it is necessary to use a slitting machine to cut the release paper. The specific structure of the slitting machine is as shown in the patent application number 202121508750. It mainly includes a feeding unit, a cutting module and a winding module. When in use, the release paper is wound onto the roller of the feeding unit, and then the roller is rotated so that it is slit by the cutting module and then conveyed to the roller of the winding module.

[0004] However, in the above structure, since the roller of the winding module needs to be rotated as a power component to pull and wind up the release paper, both ends of it need to be rotated and connected to the outer shell. This makes it inconvenient to slide the release paper off the roller after it has been cut. In the prior art, the bearing can be installed in an openable bearing seat. After the release paper is cut and wound up, the bearing seat is opened and the roller is taken out. Finally, the processed release paper is slid out of the roller to complete the unwinding. Obviously, the whole unwinding process is still quite troublesome. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a winding mechanism that solves the problem of cumbersome unwinding process for release paper in existing winding mechanisms.

[0006] According to an embodiment of the present invention, a winding mechanism includes:

[0007] First rack;

[0008] A mounting component, rotatably mounted on the first frame, having at least one take-up shaft rotatable under the drive of a power component, the take-up shaft being non-collinear with the axis of rotation of the mounting component;

[0009] A support module, configured on the first frame, is provided to support and rotate the end of the take-up shaft away from the mounting plate in at least one state during the rotation of the mounting component; otherwise, the end is suspended in the air.

[0010] The second objective of this invention is to provide a release paper slitting machine that solves the problem of the cumbersome unwinding process in existing release paper slitting machines.

[0011] According to an embodiment of the present invention, a release paper slitting machine includes:

[0012] Second rack;

[0013] The feeding mechanism and the slitting mechanism are both mounted on the second frame. The feeding mechanism can collect and deliver raw materials, and the slitting mechanism can receive the raw materials transmitted by the feeding mechanism and slitting them.

[0014] And a winding mechanism mentioned above, wherein the winding shaft is rotatable to wind up the slit raw materials.

[0015] The present invention has the following beneficial effects:

[0016] In use, the feeding mechanism transmits the material to the cutting structure, then the slitting mechanism slits the material according to the predetermined size, and finally the slitting mechanism pulls the rotating winding shaft to the winding shaft.

[0017] After winding is completed, the remaining material connected to the winding shaft is cut off. Then, the mounting component is rotated. Since the winding shaft and the mounting component are not on the same axis of rotation, the end of the winding shaft away from the mounting component can be disengaged from the support module and suspended in the air under the rotation of the mounting component. Then, the worker can slide the wound material out from that end to complete the unwinding. Compared with the prior art, the present invention only requires rotating the mounting component to remove the material and complete the unwinding, without the need to repeatedly remove or install the winding shaft, making it more convenient to use.

[0018] According to one embodiment, the take-up shaft has two shafts, which are arranged vertically in the winding state.

[0019] According to one embodiment, the support module includes rollers rotatably disposed on the first frame, the rollers being arranged in pairs with their axes parallel to the rotation axis of the take-up shaft, and at least one of the rollers being vertically elastically connected to the first frame.

[0020] According to one embodiment, both rollers supporting the same take-up shaft are vertically elastically connected to the first frame.

[0021] According to one embodiment, the support module includes a semi-circular bearing seat with multiple needle rollers on its inner wall surface, and the axes of the semi-circular bearing seat and each of the needle rollers are parallel to the axis of the take-up shaft.

[0022] The semi-circular bearing housing is vertically elastically connected to the first frame. When the mounting component rotates, it can drive the winding shaft to pass through the radial opening of the semi-circular bearing housing so as to engage with the semi-circular bearing housing.

[0023] According to one embodiment, there are four semi-circular bearing seats arranged in a rectangular pattern, and two winding shafts can be simultaneously engaged into any two of the diagonally distributed semi-circular bearing seats.

[0024] According to one embodiment, it also includes scrap rollers disposed on the first frame, with the free ends of the scrap rollers suspended in the air, and the first frame is also provided with a power mechanism to drive each of the scrap rollers to rotate.

[0025] According to one embodiment, the first frame is further provided with a first sliding assembly, which can slide along the axial direction of the scrap roller; the first sliding assembly is provided with a peeling plate to peel off the release paper located on the scrap roller during the sliding process of the first sliding assembly.

[0026] According to one embodiment, the first frame is further provided with a second sliding assembly, which can slide radially along the scrap roller, and the second sliding assembly is provided with a scraper to scrape the scrap falling from the scrap roller. Attached Figure Description

[0039] The following describes several embodiments of the present invention with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner, and in all drawings, the same reference numerals will be used to denote the same or similar elements. Features of different embodiments may be used interchangeably without conflict.

[0040] This invention provides a winding mechanism 1, which is described in detail here. Figure 1 As shown, it includes a first frame 101, a mounting component 102, and a support module 104, wherein,

[0041] The first frame 101 is in the shape of an inverted "T" and has two pieces arranged opposite each other, with a space left in the middle to form a processing groove;

[0042] A first motor 110 is mounted on the vertical rod of one of the first frames 101. The output end of the first motor 110 is connected to the mounting part 102. Starting the first motor 110 can drive the mounting part 102 to rotate. Of course, the first motor 110 can also be a handwheel. In this case, the central shaft of the handwheel passes through the first frame 101 and is fixedly connected to the mounting part 102. In this case, manually turning the handwheel can also drive the mounting part 102 to rotate. The handwheel and the first frame 101 are also provided with corresponding pin holes. By inserting a pin, the two are pinned together, thereby locking the relative position of the handwheel and the first frame 101.

[0043] A power component (motor) is fixed inside the mounting component 102. At the same time, a take-up shaft 103 is rotatably connected to the mounting component 102. One end of the take-up shaft 103 is connected to the aforementioned power component, so that the take-up shaft 103 can rotate under the drive of the power component. The take-up shaft 103 commonly uses an air shaft. By controlling the inflation and deflation of the air shaft, the release paper 5 on the take-up shaft 103 can be tightened or loosened. The specific structure of the air shaft is existing technology and will not be described in detail here.

[0044] In this embodiment, considering that the winding shaft 103 is relatively long and the release paper 5 after being cut needs to be wound on the winding shaft 103, it is not possible to keep the end of the winding shaft 103 away from the first motor 110 suspended in the air for a long time.

[0045] To address the aforementioned problems, the present invention provides two solutions. First, a support module 104 is provided on another first frame 101 facing the first motor 110. The support module 104 is also located on the vertical rod of the first frame 101. When the take-up shaft 103 is in the working state of winding the release paper 5, the support module 104 can support the end of the take-up shaft 103 away from the first motor 110 and rotate it. Second, the axis of the take-up shaft 103 is eccentrically set with respect to the rotation axis of the mounting member 102. When the mounting member 102 rotates, it can drive the take-up shaft 103 to rotate around the rotation axis of the mounting member 102, thereby detaching it from the support module 104, so that the end of the take-up shaft 103 away from the first motor 110 is suspended. At this time, the operator can slide the release paper 5 sleeved on the take-up shaft 103 from both sides of the "T"-shaped first frame 101 along the axial direction of the take-up shaft 103 to complete the unwinding.

[0046] For details, please refer to this section. Figure 1 as well as Figure 3 As shown, the support module 104 includes rollers 1041 and a fixing block 1042. The fixing block 1042 is fixedly mounted on the first frame 101. A slider (not shown in the figure) is vertically slidably connected inside the fixing block 1042, and the two are vertically elastically connected by a spring 1044 / elastic sheet or other elastic object. There are two rollers 1041, which are arranged horizontally and roll against each other. One roller 1041 is rotatably connected to the fixing block 1042, and the other roller 1041 is rotatably connected to the slider. The rotation axis of each roller 1041 is parallel to the axis of the take-up shaft 103.

[0047] Using the above scheme, when the mechanism needs to be used for winding, the power unit is activated to drive the winding shaft 103 to rotate. Since the other end of the winding shaft 103 is mounted on two rollers 1041, the rotation of the winding shaft 103 will drive the two rollers 1041 to rotate, thus achieving rolling contact between the winding shaft 103 and the two rollers 1041. After the release paper 5 is wound up, the release paper 5 connected to the winding shaft 103 is cut off manually or mechanically. Then, the first motor 110 is activated to drive the mounting component 102 to rotate, which in turn drives the winding shaft 103 to rotate around the rotation axis of the mounting component 102. Please refer to [reference needed] here. Figure 4As shown, during the rotation of the take-up shaft 103, it will press down on the right roller 1041, causing it to slide downwards to avoid the movement of the take-up shaft 103. Finally, under the drive of the first motor 110, the mounting piece 102 rotates together with the take-up shaft 103 to a horizontal state, so as to misalign the free end of the take-up shaft 103 (i.e. the end away from the first motor 110) with the vertical rod of the first frame 101, thereby making the end suspended and aligned with the cavity on the side of the first frame 101. At this time, the operator can easily slide the release paper 5 off the take-up shaft 103. When it is necessary to rewind the release paper 5, the first motor 110 is started, which drives the take-up shaft 103 to rotate in the opposite direction and press down on the roller 1041 until the take-up shaft 103 is repositioned between the two rollers 1041 to complete the reset.

[0048] The present invention also provides another embodiment, the main difference between this embodiment and the above embodiment lies in the difference in the support module 104, which is described in detail below. Figure 1 as well as Figure 2 As shown, the support module 104 in this embodiment includes a semi-circular bearing seat 1043, and its inner wall surface is provided with multiple needle rollers 1046. The specific structure and implementation principle of the semi-circular bearing seat 1043 are existing technologies and will not be described in detail here.

[0049] A support plate 1045 is also fixedly connected to the first frame 101. The axes of the semi-circular bearing seat 1043 and each needle roller 1046 are parallel to the axis of the take-up shaft 103. The semi-circular bearing seat 1043 is vertically slidably connected to the support plate 1045. The semi-circular bearing seat 1043 is also vertically elastically connected to the support plate 1045 by a spring 1044 / elastic sheet or other elastic object. The semi-circular opening 1047 of the semi-circular bearing seat 1043 is set obliquely upward, and the semi-circular bearing seat 1043 is also provided with a guide slope (not shown in the figure) to assist the take-up shaft 103 in sliding into the semi-circular bearing seat 1043 along the guide slope.

[0050] In this structure, when the take-up shaft 103 rotates under the drive of the first motor 110, it can also press down on the semi-circular bearing seat 1043, and then slide into the semi-circular bearing seat 1043 and rotate with it under the guidance of the guide slope; when it is necessary to unwind the release paper 5, the first motor 110 is started, which drives the take-up shaft 103 to rotate in the opposite direction, and press down on the semi-circular bearing seat 1043 again, and finally slide out of the semi-circular bearing seat 1043 to realize that the free end of the take-up shaft 103 is suspended.

[0051] It should be understood that the aforementioned support module 104 is not limited to the two specifically described. The above embodiments are designed only based on the premise of being feasible and convenient for operators. Of course, to further improve the stability of the mechanism's operation, cylinders, hydraulic cylinders, or other structures with telescopic functions can also be used. Specifically, taking the aforementioned semi-circular bearing seat 1043 and cylinder as an example, in this case, the opening 1047 of the semi-circular bearing seat 1043 is set upwards, and the bottom of the semi-circular bearing seat 1043 is connected to the piston rod of the cylinder. When unwinding is required, the cylinder is activated, and the winding... The semi-circular bearing seat 1043 is moved downwards until it is completely disengaged from the take-up shaft 103, thus suspending the free end of the take-up shaft 103. Then, the first motor 110 can be started to drive the take-up shaft 103 to rotate to complete the subsequent steps. Similarly, when it is necessary to rewind the release paper 5, the first motor 110 is started to drive the take-up shaft 103 to rotate in the opposite direction until it is aligned with the semi-circular bearing seat 1043. Finally, the cylinder is started and the semi-circular bearing seat 1043 is lifted to make it rotate and connect with the take-up shaft 103. At this time, the power unit is started to realize the rotation and winding of the take-up shaft 103.

[0052] The present invention also proposes another embodiment, the main difference between this embodiment and the above embodiment is that this embodiment includes a scrap roller 105, and the number of take-up rollers 103 in this embodiment is also different from that in the above embodiment;

[0053] Please refer to this section. Figure 1 as well as Figure 5 As shown, in this embodiment, the mounting component 102 is elongated, and two take-up shafts 103 are provided and rotatably connected to both ends of the mounting component 102. To ensure that the two take-up shafts 103 rotate synchronously, a transmission belt can be used to connect the two take-up shafts 103, so that when the power component drives one take-up shaft 103 to rotate, it can also drive the other take-up shaft 103 to rotate synchronously; at the same time, two sets of support modules 104 are provided accordingly.

[0054] The scrap rollers 105 are arranged in pairs and rotatably connected to two first frames 101 respectively. Each of the two first frames 101 is also equipped with a second motor 111. The output end of the second motor 111 is connected to each scrap roller 105 to drive its rotation. Each scrap roller 105 is parallel to the axis of the take-up shaft 103, and one end of each scrap roller 105 is suspended. The reason why the scrap roller 105 is allowed to be suspended is that the scrap roller 105 itself is shorter than the take-up shaft 103, and there is less residual scrap on the scrap roller 105, and it is lighter in weight. Therefore, even if one end of the scrap roller 105 is suspended, it will not affect its connection position.

[0055] In this structure, two take-up shafts 103 are distributed vertically, and a scrap roller 105 is also provided. Please refer to [reference needed]. Figure 1Taking the cutting effect of the release paper 5 as an example, it can make the two adjacent release papers 5 staggered vertically after cutting. This setting can make it convenient for staff to observe that the release paper 5 is completely cut. On the other hand, by pulling the vertically staggered release paper, it can also tear off the release paper 5 that is not completely cut and still has a small part connected.

[0056] Furthermore, to improve the working efficiency of this device, the rewind shaft 103 in this invention is also provided with two working states:

[0057] Here, we take the support module 104 in the second embodiment as an example. Please refer to... Figure 1 and Figure 2 As shown, the present invention is provided with four semi-circular bearing seats 1043 arranged in a rectangular shape, and two of the semi-circular bearing seats 1043 arranged diagonally can simultaneously support the two winding shafts 103.

[0058] In state one, both take-up shafts 103 are simultaneously supported by semi-circular bearing seats 1043 located at the upper right and lower left corners. Figure 1 (as shown in the image);

[0059] In state two, based on state one, the first motor 110 is started to drive the mounting component 102 to rotate 170° (the specific angle depends on the actual size and position of the semi-circular bearing seat 1043), so that the two winding shafts 103 are simultaneously supported by the semi-circular bearing seats 1043 located at the lower right and upper left corners.

[0060] With the above settings, the two winding shafts 103 are staggered vertically and winding the release paper 5 in state one. After winding the release paper 5 to the predetermined size and cutting off the release paper 5 connected to it, the first motor 110 is started to drive the mounting part 102 to rotate 170° until the two winding shafts 103 are in state two. Since there are still release paper 5 distributed at intervals on the winding shafts 103, at this time, it is only necessary to wrap the cut release paper 5 back onto the shaft of the winding shaft 103 that has not yet been wound with release paper 5, thereby effectively utilizing the gap between the release paper 5 on the winding shaft 103 to wind another batch of release paper 5. By switching between state one and state two, it can also be ensured that when winding two batches of release paper 5, each adjacent release paper 5 and the release paper 5 and the scrap can always be in a staggered vertical distribution state.

[0061] By adopting the above solution, the take-up shaft 103 can unwind two batches of release paper 5 after taking them up, which simplifies the overall work steps and improves the work efficiency of the institution.

[0062] Similarly, taking the support module 104 in the first embodiment as an example, two sets of rollers 1041 need to be set on the first frame 101, and the two sets of rollers 1041 are distributed vertically to support different take-up shafts 103. At the same time, two rollers 1041 in each set of rollers 1041 are vertically elastically connected to the fixing block 1042 through springs 1044. In this case, this solution also applies to the following two states.

[0063] In state one, both take-up shafts 103 are simultaneously supported by two sets of upper and lower rollers 1041;

[0064] In state two, based on state one, the first motor 110 is activated to drive the mounting component 102 to rotate 180° clockwise (in this embodiment, the two take-up shafts 103 are symmetrically distributed vertically on the horizontal plane, so the mounting component 102 can be driven to rotate 180° at this time). During this process, the upper take-up shaft 103 presses the upper right roller 1041 to disengage, and then presses the lower right roller 1041 to complete rolling contact with the two lower rollers 1041; at the same time, the lower take-up shaft 103 first presses the lower left roller 1041 to disengage, and then presses the upper left roller 1041 to complete rolling contact with the two upper rollers 1041; finally, the two take-up shafts 103 are supported by the upper and lower sets of rollers 1041.

[0065] With the above settings, the two winding shafts 103 are staggered vertically and winding the release paper 5 in state one. After winding the release paper 5 to the predetermined size and cutting off the release paper 5 connected to it, the first motor 110 is started to drive the mounting part 102 to rotate 180° until the two winding shafts 103 are in state two. Since there are still release paper 5 distributed at intervals on the winding shafts 103, at this time, it is only necessary to wrap the cut release paper 5 around the shaft of the winding shaft 103 that has not yet been wound with release paper 5, and then wind another batch of release paper 5. By switching between state one and state two, it can be ensured that when winding two batches of release paper 5, the adjacent release paper 5 and the release paper 5 and the scrap can always be staggered vertically.

[0066] The present invention also proposes another embodiment, the main difference of which is that this embodiment further includes a first sliding component 106. The first sliding component 106 is slidably connected to the first frame 101 along the direction of the scrap roller 105, and a peeling plate 107 close to the scrap roller 105 is provided at one end of the first sliding component 106 facing the inner side of the mechanism. The other end of the first sliding component 106 extends out of the first frame 101. The operator can push the first sliding component 106 to extend out of the first frame 101, so that the peeling plate 107 moves along the scrap roller 105, thereby pushing the scrap rolled onto the scrap roller 105 until it detaches from the scrap roller 105 and falls off.

[0067] Furthermore, a second sliding component 108 is slidably connected to the first frame 101 along the length of the mechanism. One end of the second sliding component 108 is provided with a scraper 109. When too much scrap material accumulates, the second sliding component 108 can be pulled to scrape the scrap material falling from the scrap roller 105 to the lower left, thus facilitating collection by the staff.

[0068] The present invention also provides a release paper slitting machine, which includes a second frame 2, a feeding mechanism 3, a slitting mechanism 4, and any of the winding mechanisms 1 mentioned above, wherein,

[0069] The feeding mechanism 3 includes an unwinding shaft 302, a third motor 301, and multiple guide rollers 304, which are rotatably connected to the second frame 2 via a bearing seat. The unwinding shaft 302 can be used to store the release paper 5. At the same time, one end of the unwinding shaft 302 is connected to the third motor 301 via a gear 303 so that it can rotate and unwind under the drive of the third motor 301 to feed the paper. The two ends of the guide rollers 304 are respectively rotatably connected to the second frame 2 to guide the release paper 5.

[0070] The slitting mechanism 4 includes a rotating shaft 402 and a plurality of annular blades 403 disposed on the rotating shaft 402. Both ends of the rotating shaft 402 are rotatably connected to the mounting base 401. At the same time, a fourth motor for driving the rotating shaft 402 to rotate is installed in the mounting base 401. The annular blades 403 are mounted on the rotating shaft 402 at equal intervals.

[0071] The winding mechanism 1 is located on the left side of the slitting mechanism 4 to wind up the release paper 5 that has been cut by multiple blades 403.

[0072] The working process of this invention is as follows: the third motor 301 drives the gear 303 and the unwinding shaft 302 to rotate, which in turn drives the release paper 5 to rotate and feed out the release paper 5 raw material. After being guided by multiple guide rollers 304, the release paper 5 raw material is transported to the slitting mechanism 4. Then, the release paper 5 is transported again and wound onto two winding shafts 103 under the cutting of multiple annular blades 403. The release paper 5 scraps cut by the two outermost blades 403 are wound onto the scrap roll. After the release paper 5 wound on the winding shaft 103 reaches the predetermined thickness, the remaining release paper 5 connected to it is cut off.

[0073] Then the first motor 110 is started to drive the take-up shaft 103 to rotate. At this time, the shaft located at... Figure 1With the upper take-up shaft 103 as a reference, the take-up shaft 103 presses down on the semi-circular bearing seat 1043 until it disengages from the semi-circular bearing seat 1043 in the upper right corner. After rotating 170°, the take-up shaft 103 presses down on the semi-circular bearing seat 1043 in the lower right corner and rotates to connect with it. Then, the release paper 5 cut by the blade 403 is wound around the remaining light rod of the take-up shaft 103. Then, the power unit is started again and the take-up shaft 103 is rotated.

[0074] After winding is complete, the release paper 5 connected to it is cut off, and the first motor 110 is restarted to drive the mounting part 102 to rotate to a horizontal state. At this time, the workers can slide the release paper 5 wound on the two winding shafts 103 from both sides of the first frame 101. At the same time, the release paper 5 located on the corner roller 105 is cut off, and the first sliding component 106 is slid to push the release paper 5 on the corner roller 105 until it falls off. Then, the second sliding component 108 is pulled to bring the fallen release paper 5 corner piece out from the depth of the mechanism, so that it is convenient for the workers to collect.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
