Description

Technical Field

[0001] This application relates to the technical field of unwinding devices, and in particular to an unwinding device and unwinding processing system. Background Technology

[0002] In the paper industry, it is difficult to avoid the situation where paper rolls are scrapped due to substandard paper quality. The common method in the industry for handling scrapped paper rolls is to use blades to cut the paper rolls into pieces, and then send the shredded paper to a paper shredder to break down the waste paper rolls for subsequent recycling.

[0003] However, the above methods require a lot of labor, and the processing is cumbersome and inefficient, resulting in high recycling costs for waste paper rolls. Summary of the Invention

[0004] One embodiment of this application provides an unwinding device, including a rotating shaft, a clamping assembly, an adjusting assembly, and a carrying assembly. The clamping assembly includes a first clamping member and a second clamping member, which cooperate to clamp the rotating shaft and are rotatable relative to the rotating shaft. The adjusting assembly is rotatably connected to the first clamping member and configured to adjust the distance between the first clamping member and the second clamping member. The carrying assembly carries the second clamping member and the adjusting assembly. The second clamping member is rotatably connected to the carrying assembly. When the first clamping member and the second clamping member clamp the rotating shaft, the adjusting assembly can adjust the rotational resistance of the rotating shaft.

[0005] Another aspect of this application provides an unwinding processing system, including a processing device and the unwinding device in the foregoing embodiments; the rotating shaft of the unwinding device is configured to carry a rolled material to be processed; the processing device has a feed inlet, and when one end of the material to be processed is placed in the feed inlet, the processing device can drive one end of the material to be processed to move relative to the feed inlet, thereby driving the rotating shaft to rotate; the adjusting component of the unwinding device can adjust the rotational resistance of the rotating shaft when the first clamping member and the second clamping member of the unwinding device cooperate to clamp the rotating shaft.

[0006] The unwinding device and unwinding system provided in this application can adjust the distance between the first clamping member and the second clamping member by adjusting the component. This allows for changing the clamping force of the first and second clamping members on the rotating shaft, thus adjusting the rolling friction between the rotating shaft and the clamping component, thereby adjusting the rotational resistance of the rotating shaft and consequently, the rotational speed of the rotating shaft. In this way, when the rotating shaft carries a roll (e.g., a paper roll), the roll and the rotating shaft can maintain a constant or specially required rotational speed. This avoids incomplete processing or blockage in the processing device (e.g., a paper shredder) due to excessively high shaft speed, allowing the rotating shaft to continuously move the material to be processed, thereby improving the processing efficiency of the material.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the structure of the unwinding device 100 in some embodiments of this application; Figure 2 yes Figure 1 A schematic diagram of the structure of the unwinding device 100 carrying the roll 102 in the embodiment; Figure 3 This is a schematic diagram of the structure of the unwinding device 100 disposed on a movable platform in some embodiments of this application.

[0021] It should be noted that the unwinding device 100 provided in this application can be used to supply materials to be processed (such as waste paper rolls) to some existing crushing devices (such as paper shredders), so that the crushing device can crush the materials to be processed supplied by the unwinding device 100, making it easier to recycle the materials to be processed. This device can also transfer and convey the materials to be processed.

[0022] Of course, the unwinding device 100 in this application can be used for transferring waste paper rolls 101, and can also be used for transferring other materials to be processed, such as plastic film rolls, cloth rolls, and other materials that can be unwound in the form of a roll. In the following embodiments of this application, the transfer of waste paper rolls 101 is used as an example for illustration. The application of this application to other roll-type materials will not be described in detail in this application.

[0023] The "shredding device" or "paper shredder" mentioned in this application, which is capable of shredding waste paper roll 101, is preferably a shredding device with a built-in negative pressure fan. When shredding waste paper roll 101, the shredding device mentioned in this application can rely on its internal negative pressure fan to provide a constant and continuous suction force, thereby drawing the paper from waste paper roll 101 into the shredding device 200. The shredding device 200 has built-in rotating blades or other structural components capable of cutting and shredding the paper drawn into it.

[0024] The unwinding device 100 provided in this application can be fixed, for example, the unwinding device 100 is directly installed on the ground or on a fixed platform that cannot be moved; or it can be non-fixed, for example, the unwinding device 100 can be installed on a movable platform or on a trolley with a braking function. Figure 3 As shown, when the unwinding device 100 is mounted on a movable platform or trolley, the transfer efficiency of the unwinding device 100 for the waste paper roll 101 can be further improved.

[0025] Please see Figure 4 , Figure 4 yes Figure 1 An enlarged schematic diagram of part A in the embodiment.

[0026] The unwinding device 100 provided in this application may include a rotating shaft 110, a clamping assembly 120, an adjusting assembly 130, and a supporting assembly 140. The clamping assembly 120 may include a first clamping member 121 and a second clamping member 122. The first clamping member 121 and the second clamping member 122 cooperate to clamp the rotating shaft 110, and the rotating shaft 110 is rotatable relative to the first clamping member 121 and the second clamping member 122. The adjusting assembly 130 may be rotatably connected to the first clamping member 121. The adjusting assembly 130 may be configured to adjust the distance between the first clamping member 121 and the second clamping member 122. Both the second clamping member 122 and the adjusting assembly 130 may be disposed on the supporting assembly 140, which provides support for the second clamping member 122 and the adjusting assembly 130.

[0027] Furthermore, the second clamping member 122 can be rotatably connected to the support assembly 140. Since the adjusting assembly 130 can adjust the distance between the first clamping member 121 and the second clamping member 122, it can also adjust the distance between the first clamping member 121, the second clamping member 122, and the rotating shaft 110. By adjusting the distance between the first clamping member 121, the second clamping member 122, and the rotating shaft 110 through the adjusting assembly 130, the tightness between the rotating shaft 110 and the first clamping member 121 and the second clamping member 122 can be changed, i.e., the pressure between the rotating shaft 110 and the first clamping member 121 and the second clamping member 122 can be changed, thereby changing the rotational resistance of the rotating shaft 110.

[0028] Please see Figure 4 and Figure 5 , Figure 5 This is a schematic diagram of the structure of some embodiments of this application for supplying waste paper rolls 101 to a shredding device.

[0029] When the rotating shaft 110 of this application carries a waste paper roll 101, and the unwinding device 100 is used to supply waste paper to the crushing device 200, one end of the paper from the waste paper roll 101 is guided into the feed inlet 202 of the crushing device 200. Under the constant suction of the crushing device 200, the crushing device 200 can suck the paper from the waste paper roll 101 into the crushing device 200, thereby driving the rotating shaft 110 carrying the waste paper roll 101 to rotate.

[0030] If the rotational resistance of the shaft 110 is very small, the suction of the crushing device 200 can easily draw the waste paper from the waste paper roll 101 into the feed inlet 202 of the crushing device 200. This may result in a large amount of waste paper being drawn into the feed inlet 202 of the crushing device 200, which may cause a large amount of waste paper to clog the feed inlet 202 of the crushing device 200 due to untimely waste paper processing. If the rotational resistance of the shaft 110 is too large, the suction provided by the crushing device 200 is not enough to drive the shaft 110 to rotate through the paper in the waste paper roll 101. This may result in the crushing device 200 being unable to continuously crush the paper in the waste paper roll 101.

[0031] Whether the feed inlet 202 of the crushing device 200 is blocked or the paper cannot be effectively sucked into the crushing device 200, the crushing efficiency of the crushing device 200 on the waste paper roll 101 will be reduced, thereby increasing the recycling cost of waste paper. Therefore, by adjusting the distance between the first clamping member 121 and the second clamping member 122 by adjusting the component 130, that is, changing the distance between the first clamping member 121 and the second clamping member 122 relative to the rotating shaft 110, the tightness between the rotating shaft 110 and the corresponding clamping member can be changed, thereby achieving adjustable rotational resistance of the rotating shaft 110.

[0032] When the rotational resistance of the rotating shaft 110 is adjusted to a suitable level, the paper in the waste paper roll 101 can be continuously and uninterruptedly sucked into the crushing device 200, achieving uninterrupted processing of the paper in the waste paper roll 101. This avoids situations where waste paper gets stuck in the crushing device 200 due to excessively fast waste paper suction speed, or where waste paper cannot continuously enter the crushing device 200 due to excessively slow waste paper suction speed. This, in turn, increases the crushing speed of the crushing device 200 on the waste paper roll 101 and reduces the recycling cost of waste paper.

[0033] It should be noted that the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] Please see Figure 5 and Figure 6 , Figure 6 This is a partial structural schematic diagram of the unwinding device in some embodiments of this application.

[0035] The shaft 110 in the uncoiling device 100 can be a cylindrical shaft that can be removed from the uncoiling device 100. The shaft 110 can be a metal structural component with good rigidity and toughness, and can be integrally formed by processes such as stamping and casting.

[0036] The carrier assembly 140 may have a carrier end 141 and a connecting end 142 spaced apart from the carrier end 141. The connecting end 142 is configured for positioning the unwinding device 100.

[0037] Specifically, the connecting end 142 can be a fixed structure or a movable structure set on a horizontal plane. The fixed structure can be a fixed frame set on the corresponding plane or a vertical pole set on the corresponding plane, etc. The movable structure can be a trolley with a braking function or other movable platform. It should be noted that when the connecting end 142 of the unwinding device 100 is a movable platform or trolley (e.g....), Figure 3 As shown, this can further improve the transfer efficiency of the unwinding device 100 to the waste paper roll 101, thereby further reducing the recycling cost of the unwinding device 100 to the waste paper roll 101.

[0038] Furthermore, the bearing end 141 may be a structural end spaced apart from the connecting end 142 and used to support the rotating shaft 110. A second clamping member 122 is spaced apart on the bearing end 141. The second clamping member 122 may include at least one bearing assembly 1220 rotatably connected to the bearing end 141. The bearing assembly 1220 is capable of rolling engagement with the rotating shaft 110.

[0039] Specifically, the second clamping member 122 may include two bearing assemblies 1220. Each bearing end 141 corresponds to one second clamping member 122, and the two bearing assemblies 1220 of the second clamping member 122 may be symmetrically arranged at their respective bearing ends 141. The two bearing assemblies 1220 may form a support structure capable of supporting the rotating shaft 110. When the two bearing assemblies 1220 support the rotating shaft 110, the rotating shaft 110 can rotate around its central axis on the two bearing assemblies 1220.

[0040] Please refer to the following: Figure 7 , Figure 7 yes Figure 6 A schematic diagram of the bearing assembly 1220 on the unwinding device 100 in the embodiment. The bearing assembly 1220 may include a shaft portion 1221 passing through the bearing end 141 and a wheel portion 1222 sleeved on the shaft portion 1221, wherein the wheel portion 1222 can rollly engage with the rotating shaft 110.

[0041] Specifically, each bearing assembly 1220 may include a shaft portion 1221 and two wheel portions 1222. The shaft portion 1221 may be a strip-shaped shaft passing through the bearing end 141, and the wheel portions 1222 may be ball bearings mounted on the shaft portion 1221. When the shaft portion 1221 passes through the bearing end 141, the two wheel portions 1222 are spaced apart on the shaft portion 1221 and are respectively close to both ends of the shaft portion 1221. The wheel surface of the wheel portion 1222 is perpendicular to the length direction of the shaft portion 1221 in which it is located, and the two wheel portions 1222 are respectively located on both sides of the corresponding bearing end 141 on the corresponding shaft portion 1221.

[0042] More specifically, a portion of the wheel portion 1222 located on the shaft portion 1221 protrudes from the end face of the bearing end 141, opposite to the connecting end 142. Two bearing assemblies 1220 (i.e., the second clamping member 122 provided on the bearing end 141) are symmetrically arranged on the same bearing end 141, with four corresponding wheel portions 1222. The four wheel portions 1222 extend out of the corresponding bearing end 141 and form the aforementioned support structure that can support the rotating shaft 110. The rotating shaft 110 is rotatably connected between the two bearing assemblies 1220 on the same bearing end 141.

[0043] Please see Figure 6 and Figure 8 , Figure 8This is a partially exploded structural diagram of the unwinding device 100 in some embodiments of this application. The adjusting assembly 130 may include a connecting shaft 131, a moving member 132, and an adjusting member 133. The connecting shaft 131 is disposed at the bearing end 141, the moving member 132 is sleeved on the connecting shaft 131 and is capable of moving along the axial direction of the connecting shaft 131, and the adjusting member 133 is configured to adjust the position of the moving member 132.

[0044] Specifically, two connecting shafts 131 can be provided at the bearing end 141, with the two connecting shafts 131 spaced apart and located on both sides of the second clamping member 122. The moving member 132 corresponds to the bearing end 141, and can be sleeved on the two connecting shafts 131 on the bearing end 141, and can slide along the axial direction of the connecting shafts 131. The first clamping member 121 can be rotatably connected to the moving member 132. The adjusting member 133 can be used to fix the position of the moving member 132 on the connecting shafts 131, and the position of the moving member 132 on the connecting shafts 131 can be adjusted by the adjusting member 133.

[0045] More specifically, the movable member 132, the first clamping member 121, the bearing end 141, and the second clamping member 122 can form a receiving cavity 300 to facilitate the insertion of the rotating shaft 110 therein. The rotating shaft 110 is inserted into the receiving cavity 300 and can be clamped within the receiving cavity 300 by the action of the first clamping member 121 and the second clamping member 122.

[0046] Furthermore, the adjusting member 133 can be located on the side of the moving member 132 away from the bearing end 141 and threadedly connected to the corresponding connecting shaft 131.

[0047] When the rotating shaft 110 is clamped within the accommodating cavity 300, the position of the moving member 132 on the connecting shaft 131 can be changed by rotating the adjusting member 133, thereby adjusting the distance between the first clamping member 121 and the second clamping member 122 relative to the rotating shaft 110. The change in the distance between the first clamping member 121 and the second clamping member 122 relative to the rotating shaft 110 alters the tightness between the first clamping member 121, the second clamping member 122, and the rotating shaft 110, thereby changing the rotational resistance of the rotating shaft 110.

[0048] In some embodiments, the adjusting member 133 may be a screw or nut threaded onto the connecting shaft 131. By rotating the corresponding adjusting member 133, the position of the adjusting member 133 on the corresponding connecting shaft 131 can be changed, thereby changing the distance between the moving member 132 and the bearing end 141, and thus changing the clamping degree between the first clamping member 121 and the rotating shaft 110.

[0049] Furthermore, the adjusting assembly 130 may also include an elastic element 134. The elastic element 134 may be disposed between the bearing end 141 and the moving element 132.

[0050] Specifically, the elastic element 134 is preferably a spring. The elastic element 134 can be sleeved on the corresponding connecting shaft 131, and its two ends respectively abut against the moving element 132 and the bearing end 141. By rotating the adjusting element 133, the position of the adjusting element 133 on the connecting shaft 131 can be changed, thereby changing the distance between the moving element 132 and the bearing end 141, thus changing the tightness between the first clamping element 121 and the rotating shaft 110, and consequently changing the rotational resistance of the rotating shaft 110. Of course, in other embodiments, the elastic element 134 can also be an elastic structure capable of elastic deformation.

[0051] Please refer to the following: Figure 5 When the waste paper roll 101 is fitted onto the rotating shaft 110, the adjusting member 133 is moved to a suitable position (i.e., the rotational resistance of the rotating shaft 110 is adjusted to a suitable level). Then, one end of the paper in the waste paper roll 101 is introduced into the feed inlet 202 of the crushing device 200. Relying on the suction at the feed inlet 202 of the crushing device 200, the waste paper roll 101 can be automatically fed into the crushing device 200, and the waste paper in the waste paper roll 101 can be continuously and uninterruptedly fed. Compared with the situation where too much paper is sucked into the crushing device 200 due to the low rotational resistance of the rotating shaft 110, which may cause blockage of the crushing device 200, this embodiment has higher waste paper processing / transfer efficiency and can reduce the cost of waste paper processing.

[0052] Please continue reading. Figure 8 In some embodiments, the movable member 132 may include a first connecting portion 1321, a second connecting portion 1322, and a third connecting portion 1323. The second connecting portion 1322 is disposed between the first connecting portion 1321 and the third connecting portion 1323. Optionally, the opposite ends of the second connecting portion 1322 are bent and connected to the first connecting portion 1321 and the third connecting portion 1323, respectively. In other words, the first connecting portion 1321 and the third connecting portion 1323 are located on the same side of the second connecting portion 1322 and are connected to the opposite ends of the second connecting portion 1322, respectively. It is understood that the connection between the first connecting portion 1321 and the second connecting portion 1322 can be a bent connection, or it can be a smooth transition connection, etc. The connection between the third connecting portion 1323 and the second connecting portion 1322 can also be a bent connection, or it can be a smooth transition connection, etc.

[0053] In one embodiment, the first connecting portion 1321 and the third connecting portion 1323 can be straight plates symmetrically arranged on both sides of the second connecting portion 1322, and the second connecting portion 1322 can be an isosceles trapezoidal plate arranged in an arch shape. The planar sides of the first connecting portion 1321, the third connecting portion 1323 and the second connecting portion 1322 can be arranged parallel to each other, wherein the bending direction of the second connecting portion 1322, that is, the isosceles trapezoidal plate, is the side away from the bearing end 141.

[0054] The first clamping member 121 is rotatably connected to the second connecting part 1322, and the rotating shaft 110 passes through the accommodating cavity 300 formed by the moving member 132, the first clamping member 121, the bearing end 141, and the second clamping member 122. The first clamping member 121 is rotatably connected to the second connecting part 1322.

[0055] Specifically, the first clamping member 121 can be a wheel-type structure. The planar side of the second connecting part 1322 can be provided with a through hole, and the first clamping member 121 can be rotatably connected in the through hole. When the rotating shaft 110 passes through the accommodating cavity 300, both the first clamping member 121 and the second clamping member 122 are in contact with the rotating shaft 110 and can rotate relative to the rotating shaft 110.

[0056] Please continue reading. Figure 8 In some embodiments, the connecting shaft 131 may include a first connecting shaft 1311 and a second connecting shaft 1312. A first connecting portion 1321 is sleeved on the first connecting shaft 1311, and a third connecting portion 1323 is sleeved on the second connecting shaft 1312. An elastic member 134 is disposed between the first connecting portion 1321 and the bearing end 141, and an adjusting member 133 is disposed on the side of the third connecting portion 1323 opposite to the bearing end 141 and is threadedly connected to the second connecting shaft 1312.

[0057] Furthermore, the adjustment assembly 130 may also include a fastener 135 disposed on the first connecting shaft 1311, the fastener 135 being configured to limit the travel of the moving member 132.

[0058] Specifically, the elastic element 134 can preferably be a spring, which is sleeved on the first connecting shaft 1311, and its two ends can respectively abut against the first connecting portion 1321 and the bearing end 141. The fastener 135 can be a nut disposed on the side of the moving member 132 away from the bearing end 141, that is, on the side of the first connecting portion 1321 away from the bearing end 141. The nut can be threaded onto the first connecting shaft 1311, and its position on the first connecting shaft 1311 can be changed by rotating the nut, thereby being configured to limit the travel of the moving member 132.

[0059] The adjusting member 133 is preferably a screw barrel that can be threadedly connected to the second connecting shaft 1312. The screw barrel is located on the side of the third connecting portion 1323 away from the bearing end 141 on the second connecting shaft 1312. By rotating the screw barrel, the position of the screw barrel on the second connecting shaft 1312 can be changed, thereby changing the distance between the moving member 132 and the bearing end 141. When the rotating shaft 110 is clamped between the first clamping member 121 and the second clamping member 122, rotating the screw barrel can change the tightness between the first clamping member 121 on the second connecting portion 1322 and the rotating shaft 110, thereby changing the rotational resistance of the rotating shaft 110.

[0060] Please see Figure 6 , Figure 8 and Figure 9 , Figure 9 This is a side view of the unwinding device 100 in some embodiments of this application.

[0061] In this embodiment, the supporting component 140 may include a first upright 1401 and a second upright 1402 that are spaced apart.

[0062] The uprights (1401, 1402) can be rod-shaped structural members fixed to a load-bearing structure. The load-bearing structure can be a fixed load-bearing surface, such as the ground, a fixed or movable platform, etc. The first upright 1401 and the second upright 1402 can be erected vertically on the corresponding load-bearing structure, and the first upright 1401 and the second upright 1402 are parallel to each other on the corresponding load-bearing structure.

[0063] In this embodiment, the rotating shaft 110 has a first end 111 and a second end 112 disposed opposite to each other. The first end 111 and the second end 112 correspond to the first upright 1401 and the second upright 1402, respectively. Two clamping assemblies 120 may be provided, with the two clamping assemblies 120 respectively disposed on the first upright 1401 and the second upright 1402, and respectively corresponding to the first end 111 and the second end 112 of the rotating shaft 110. The two ends of the rotating shaft 110 are clamped to the two uprights by the two clamping assemblies 120.

[0064] There are two adjustment components 130, which correspond to the first upright 1401 and the second upright 1402 respectively, and are respectively installed on the corresponding uprights.

[0065] Specifically, the second clamping member 122 of the clamping assembly 120 is disposed on the corresponding first upright 1401 or second upright 1402. Two bearing assemblies 1220 of the second clamping member 122 are rotatably connected to the corresponding upright, and both bearing assemblies 1220 are located away from the load-bearing structure on the corresponding upright. The two bearing assemblies 1220 are symmetrically arranged on the corresponding upright, and the ends of the two bearing assemblies 1220 that are away from the load-bearing structure protrude from the end face of the corresponding upright.

[0066] More specifically, an arc-shaped groove 1400 can be formed at the end of the upright that is away from the load-bearing structure on which the upright is located, and the groove surface of the arc-shaped groove 1400 is bent toward the side away from the adjusting component 130. The two bearing assemblies 1220 of the second clamping member 122 can be arranged along the extension direction of the arc-shaped groove 1400 and can be symmetrically distributed about the center line of the arc-shaped groove 1400. The two bearing assemblies 1220 protrude from the end face of the corresponding upright at the end of the upright that is away from its load-bearing structure. The two bearing assemblies 1220 protruding from the end face of the upright can form a support structure for supporting the rotating shaft 110. The rotating shaft 110 is placed on the support structure composed of the two bearing assemblies 1220 and can rotate relative to the two bearing assemblies 1220.

[0067] The movable component 132 in the adjusting assembly 130 may include a first connecting portion 1321, a second connecting portion 1322, and a third connecting portion 1323. The second connecting portion 1322 is connected between the first connecting portion 1321 and the third connecting portion 1323. The first connecting portion 1321 and the third connecting portion 1323 may be straight plates symmetrically arranged on both sides of the second connecting portion 1322, while the second connecting portion 1322 may be an isosceles trapezoidal plate with an arched shape. The planar sides of the first connecting portion 1321, the third connecting portion 1323, and the second connecting portion 1322 may be parallel, and the bending direction of the second connecting portion 1322, i.e., the isosceles trapezoidal plate, is away from the side opposite to the bearing end 141.

[0068] The first clamping member 121 is rotatably connected to the second connecting part 1322. The rotating shaft 110 passes through the accommodating cavity 300 formed by the moving member 132, the first clamping member 121, the end face of the upright, and the second clamping member 122. The rotating shaft 110 is rotatable relative to the first clamping member 121 and the second clamping member 122.

[0069] The two adjustment components 130 correspond to the first end 111 and the second end 112 of the rotating shaft 110, which is mounted on two uprights. The first end 111 and the second end 112 of the rotating shaft 110 are clamped by the clamping components 120 on the corresponding uprights.

[0070] The connecting shaft 131 in the adjusting assembly 130 is disposed at the end of the corresponding upright. The connecting shaft 131 may include a first connecting shaft 1311 and a second connecting shaft 1312. The first connecting shaft 1311 and the second connecting shaft 1312 may be located on both sides of the second clamping member 122 at the end of the corresponding upright. The first connecting shaft 1311 and the second connecting shaft 1312 correspond to the first connecting part 1321 and the third connecting part 1323, respectively.

[0071] The first connecting shaft 1311 can be a straight shaft located at the end of the upright. The first connecting part 1321 is sleeved on the first connecting shaft 1311 and can slide along the first connecting shaft 1311. A fastener 135, which can be threadedly connected to the first connecting shaft 1311, is provided on the side of the first connecting part 1321 opposite to the corresponding upright. The fastener 135 can preferably be a nut, which can limit the distance between the moving part 132 and the upright when the fastener 135 is rotated.

[0072] Furthermore, an elastic element 134 may be provided between the first connecting part 1321 and the corresponding end of the upright. The elastic element 134 may preferably be a spring, which is sleeved on the first connecting shaft 1311, and the two ends of the spring abut against the end face of the first connecting part 1321 and the upright, respectively.

[0073] The second connecting shaft 1312 can be a straight shaft hinged to the end of the pole. The third connecting part 1323 has a slot 13231 corresponding to the second connecting shaft 1312. Rotating the second connecting shaft 1312 can rotate the second connecting shaft 1312 into the corresponding slot 13231.

[0074] Specifically, the second connecting shaft 1312 can be hinged to the end of the upright via a U-shaped rotating seat. The second connecting shaft 1312 can be fixed on the corresponding U-shaped rotating seat, and the rotation direction of the second connecting shaft 1312 on the upright can be parallel to the radial section of the corresponding bearing assembly 1220.

[0075] When the second connecting shaft 1312 is turned, it rotates into the slot 13231 on the third connecting part 1323. When the second connecting shaft 1312 is turned into the corresponding slot 13231, the adjusting member 133 is mounted on the second connecting shaft 1312. The adjusting member 133 is preferably a screw cylinder that can be threadedly connected to the second connecting shaft 1312. When the second connecting shaft 1312 rotates into the corresponding slot 13231, the adjusting member 133 is threadedly connected to the second connecting shaft 1312, which allows the third connecting part 1323 to be fastened between the screw cylinder and the corresponding end of the upright, thereby achieving the fastening of the end of the rotating shaft 110.

[0076] Optionally, a lever 1331 can be fixed on the side wall of the adjusting member 133. The lever 1331 can make it easier to rotate the adjusting member 133, thereby making it easier for the operator to change the rotation resistance of the rotating shaft 110. At the same time, it can also make it easier to disconnect the moving member 132 from the corresponding upright.

[0077] When the rotating shaft 110 rotates away from the slot 13231 on the third connecting part 1323, the movable part 132 can rotate around the central axis of the first connecting shaft 1311, so that the movable part 132 can rotate away from the corresponding end of the rotating shaft 110, thereby releasing the restriction on the end of the rotating shaft 110, and enabling the disassembly of the rotating shaft 110 on this unwinding device 100.

[0078] Please see Figure 9 and Figure 10 , Figure 10 yes Figure 9 A schematic diagram of a partial cross-sectional structure in the AA direction in the embodiment.

[0079] The unwinding device 100 may include a limiting assembly 400 disposed on the rotating shaft 110. The limiting assembly 400 is configured to limit the position of the drum 102 mounted on the rotating shaft 110. The limiting assembly 400 includes a first limiting member 410 sleeved on the rotating shaft 110 and a second limiting member 420 slidably connected to the rotating shaft 110. The first limiting member 410 and the second limiting member 420 are capable of clamping the drum 102 on the rotating shaft 110.

[0080] It should be noted that the roll 102 in this embodiment can be a discarded paper roll, cloth roll, or plastic roll, etc. When the roll 102 is mounted on the rotating shaft 110, the first limiting member 410 and the second limiting member 420 can clamp and limit the roll 102.

[0081] Specifically, the first limiting member 410 can be a plate perpendicular to the axial direction of the rotating shaft 110. Preferably, the first limiting member 410 is a flange sleeved on the rotating shaft 110. The flange can be detachably mounted on the rotating shaft 110 by bolts. When the bolts on the flange are loosened, the flange can be released from its fastening on the rotating shaft 110, thereby changing the position of the flange on the rotating shaft 110.

[0082] Furthermore, a movable cavity 1100 may be provided at one end of the rotating shaft 110. The movable cavity 1100 may be a cavity coaxially arranged with the rotating shaft 110. A limiting hole 1101 that communicates with the movable cavity 1100 is provided on the circumferential side of the rotating shaft 110. The second limiting member 420 may pass through the limiting hole 1101 and may move relative to the rotating shaft 110 in the axial direction. The limiting hole 1101 may be used to limit the stroke of the second limiting member 420 on the rotating shaft 110.

[0083] The adjusting assembly 130 in this embodiment may further include a lead screw 136. The lead screw 136 is inserted into the movable cavity 1100 and can be threadedly connected to the second limiting member 420. When the lead screw 136 rotates, it can drive the second limiting member 420 to move relative to the rotating shaft 110.

[0084] Specifically, the movable cavity 1100 can be a hollow cavity coaxially arranged with the rotating shaft 110. The second limiting member 420 can be a plate perpendicular to the axial direction of the rotating shaft 110. Specifically, the second limiting member 420 can be a flat plate with its surface perpendicular to the axial direction of the rotating shaft 110. The limiting hole 1101 can be a strip-shaped hole parallel to the axial direction of the rotating shaft 110. When the second limiting member 420 passes through the limiting hole 1101 and is threadedly connected to the lead screw 136, the two side surfaces of the second limiting member 420 relative to the sidewall of the limiting hole 1101 can contact the corresponding hole wall of the limiting hole 1101. This prevents the second limiting member 420 from rotating with the lead screw 136 when the lead screw 136 is rotated, allowing the second limiting member 420 to move along the length direction of the limiting hole 1101. This changes the position of the second limiting member 420 on the rotating shaft 110, thereby enabling the first limiting member 410 and the second limiting member 420 to limit the position of the material roll 102.

[0085] Unlike the above embodiments, in this embodiment, multiple limiting holes 1101 can be provided, and the multiple limiting holes 1101 are evenly distributed on the side of the rotating shaft 110 around the central axis of the rotating shaft 110. Multiple second limiting members 420 corresponding to the limiting holes 1101 can also be provided, and the multiple second limiting members 420 correspond one-to-one with the multiple limiting holes 1101.

[0086] When this application provides multiple second limiting members 420, all of the multiple second limiting members 420 can be fixed on the same mounting cylinder 1102. The mounting cylinder 1102 can be a cylindrical structure disposed in the movable cavity 1100 and threadedly connected to the lead screw 136. The multiple second limiting members 420 are respectively inserted into the corresponding movable holes and connected to the outer side wall of the mounting cylinder 1102. The plate surfaces of the multiple second limiting members 420 are all located on the same plane and are all perpendicular to the axis of the rotating shaft 110.

[0087] When the lead screw 136 is rotated, the mounting cylinder 1102 cannot rotate with the lead screw 136 due to the action of multiple second limiting members 420, thus enabling relative rotation between the lead screw 136 and the mounting cylinder 1102. When relative rotation occurs between the lead screw 136 and the mounting cylinder 1102, the second limiting members 420 provided on the side wall of the mounting cylinder 1102 can move relative to the rotating shaft 110 along the length direction of the limiting hole 1101. This allows the position of the second limiting members 420 on the rotating shaft 110 to be variable.

[0088] Unlike the above embodiments, at least one bearing seat 1103 may be installed in the movable cavity 1100 of this embodiment.

[0089] Specifically, the bearing housing 1103 can be coaxially arranged with the movable cavity 1100. The lead screw 136 is inserted into the movable cavity 1100, one end of which can extend out of one side of the movable cavity 1100, and the other end passes through the corresponding bearing housing 1103 and is threadedly connected to the corresponding mounting sleeve 1102 or the second limiting member 420.

[0090] The bearing housing 1103 can stabilize and support the lead screw 136, and the bearing housing 1103 can make the lead screw 136 rotate more smoothly in the movable cavity 1100.

[0091] Optionally, a rotating component 1104 may be installed at one end of the lead screw 136 extending out of the movable cavity 1100 to facilitate the rotation of the lead screw 136. The rotating component 1104 may be a wheel-type structure, such as a wheel or handwheel; the rotating component 1104 may also be an L-shaped rod fixed to the lead screw 136 or other rods that can form a certain angle with the lead screw 136.

[0092] Rotating the rotating component 1104 easily rotates the lead screw 136. In this embodiment, the rotating component 1104 is preferably a handwheel, and a handle 11041 can be fixed to the edge of the corresponding wheel surface on the side of the handwheel away from the rotating shaft 110. The lead screw 136 can also be driven by the handle 11041.

[0093] Unlike the above embodiments, in this embodiment, a plurality of ejector pins 411 are provided on the plate surfaces of both the first limiting member 410 and the second limiting member 420. The plurality of ejector pins 411 are evenly distributed on the corresponding plate surfaces of the first limiting member 410 and the second limiting member 420.

[0094] Specifically, the ejector pin 411 can be a shaft-type structural component with a pointed end, such as a screw or pin. The pointed ends of the ejector pin 411 correspond to each other on the first limiting member 410 and the second limiting member 420.

[0095] When a (material-type) drum 102 is provided on the rotating shaft 110, the first limiting member 410 can be set at a suitable position on the rotating shaft 110 and make the first limiting member 410 abut against one end face of the drum 102. At the same time, ensure that the ejector pin 411 on the first limiting member 410 can be inserted into the corresponding end face of the drum 102. Then move the second limiting member 420 so that the other end face of the drum 102 abuts against the second limiting member 420 and the ejector pin 411 on the second limiting member 420 is inserted into the corresponding end face of the drum 102, so that the drum 102 can be clamped between the first limiting member 410 and the second limiting member 420.

[0096] When it is necessary to change the position of the second limiting member 420 on the rotating shaft 110, the rotating member 1104 can be rotated. The rotating member 1104 can drive the lead screw 136 to rotate, which in turn can drive the second limiting member 420 to move on the rotating shaft 110, thereby enabling the second limiting member 420 to abut against one end face of the drum 102.

[0097] Meanwhile, the ejector pins 411 provided on the first limiting member 410 and the second limiting member 420 can be inserted into the corresponding end face of the drum 102, which can ensure the synchronous rotation of the rotating shaft 110 and the drum 102 and prevent slippage between the rotating shaft 110 and the drum 102.

[0098] In this embodiment, by changing the position of the first limiting member 410 on the rotating shaft 110 or changing the position of the second limiting member 420 relative to the limiting hole 1101, the distance between the first limiting member 410 and the second limiting member 420 can be changed, thereby enabling this application to be applied to the transfer of rolls 102 of different widths, thus making the application scope of this application wider.

[0099] When transferring or unwinding the roll 102, the adjusting member 133 or fastener 135 on the connecting shaft 131 can be removed first. Then, the moving member 132 can be removed from the unwinding device 100, thereby releasing the restriction of the moving member 132 on the rotating shaft 110. The rotating shaft 110 is then removed from the unwinding device 100 and inserted into the roll 102 to be unwound / transferred. A forklift or similar lifting device is then used to transport the rotating shaft 110 with the roll 102 attached to it to the corresponding upright and place it on the corresponding second clamping member 122, i.e., the bearing assembly 1220. The moving member 132 is then repositioned on the corresponding connecting shaft 131 using the adjusting member 133 or fastener 135. Finally, one end of the material on the drum 102 is led to the feed inlet 202 of the crushing device 200. The crushing device 200 can generate a certain suction force on the material on the drum 102. The suction force of the crushing device 200 can drive the drum 102 to rotate through the material on the drum 102, thereby allowing the material on the drum 102 to enter the crushing device 200, thereby realizing the crushing and recycling of the material on the drum 102 by the crushing device 200.

[0100] During the rotation of the drum 102, the pressure between the rotating shaft 110 and the first clamping member 121 can be adjusted by changing the distance between the adjusting member 133 and the corresponding upright, thereby changing the rotational resistance of the rotating shaft 110. This allows the material on the drum 102 to be continuously sucked into the feed inlet 202 of the crushing device 200 under the suction of the crushing device 200 without any blockage.

[0101] When it is necessary to install the roll 102 on the rotating shaft 110, the rotating shaft 110 should be inserted into the roll 102 from the end away from the rotating member 1104. When one end face of the roll 102 abuts against the second limiting member 420, the first limiting member 410 is then sleeved on the rotating shaft 110 from the end away from the rotating member 1104. Then, the first limiting member 410 is moved towards the roll 102. When the first limiting member 410 abuts against the end face of the roll 102 away from the second limiting member 420, the first limiting member 410 is then fastened to the rotating shaft 110 with bolts, thereby achieving the limiting and reinforcement of the paper roll by the first limiting member 410 and the second limiting member 420. Then, the rotating shaft 110, which is equipped with the first limiting member 410 and the second limiting member 420 and has the drum 102, is transferred to the corresponding second clamping member 122 by a forklift or other equipment, so as to realize the setting of the drum 102 on the rotating shaft 110.

[0102] Please see Figure 5 This application also provides an unwinding processing system, which may include a processing device 201 and the unwinding device 100 in the foregoing embodiments. The unwinding device 100 has a rotating shaft 110 configured to carry a material to be processed in the shape of a roll 102. The processing device 201 has a feed inlet 202. When one end of the material to be processed is placed in the feed inlet 202, the processing device 201 can drive one end of the material to be processed to move relative to the feed inlet 202, thereby driving the rotating shaft 110 to rotate. The adjusting component 130 of the unwinding device 100 can adjust the rotational resistance of the rotating shaft 110 when the first clamping member 121 and the second clamping member 122 of the unwinding device 100 cooperate to clamp the rotating shaft 110.

[0103] Specifically, the material to be processed in a roll shape can be a waste paper roll 101, a cloth roll, or a plastic film roll, etc. The processing device 201 can be a crushing device 200 capable of crushing the roll-shaped material to be processed, and the feed port 202 of the crushing device 200 can provide a constant suction force for the roll-shaped material to be processed.

[0104] For example, when the roll 102 is a waste paper roll and the processing device 201 is a paper shredder, one end of the paper on the waste paper roll 101 is introduced into the feed port 202 of the paper shredder. Under the suction provided by the paper shredder, the paper on the waste paper roll 101 can be continuously sucked into the paper shredder, thereby realizing the crushing and processing of the waste paper on the waste paper roll 101.

[0105] When the processing device 201 processes the rolled material, the distance between the moving member 132 and the bearing end 141 / upright can be changed by altering the position of the adjusting member 133 on the corresponding connecting shaft 131. This, in turn, changes the distance between the first clamping member 121 and the second clamping member 122, enabling adjustment of the clamping force / pressure of the first clamping member 121 and the second clamping member 122 on the rotating shaft 110, thereby changing the rotational resistance of the rotating shaft 110.

[0106] When the rotational resistance of the rotating shaft 110 is adjusted to a suitable level, the speed at which the drum 102 releases the material to be processed can be kept consistent with the processing speed of the processing device 201. This avoids a situation where the suction provided by the processing device 201 is too strong, causing the drum 102 to release the material to be processed too quickly. It also prevents the processing device 201 from being unable to process the sucked-in material in a short time due to the excessively fast discharge speed of the drum 102, resulting in a large accumulation of material at the feed inlet 202 of the processing device 201, causing blockage, and consequently reducing the efficiency of the material being processed on the drum 102, thus increasing the processing cost.

[0107] Of course, in other embodiments, the processing device 201 can also be a non-crushing device. For example, in the printing field, the roll 102 can be a complete, good paper roll. When continuous, uninterrupted printing is required on the paper on the roll, the processing device 201 can be a printing device capable of continuously attracting the paper on the roll into the feed inlet 202 of the processing device 201. In the garment manufacturing field, the roll 102 can be a fabric roll. When continuous cutting of the fabric on the roll is required, the processing device 201 can be a cutting device capable of continuously attracting the fabric on the roll into the feed inlet 202 of the processing device 201. Further applications of this application will not be elaborated upon in this application.

[0108] It should be noted that the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to those processes, methods, products, or setups.

[0109] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
