Description

Technical Field

[0001] This utility model belongs to the field of core recycling for winding, specifically a core and roll material recycling device, and in particular a core and roll material recycling device that can quickly realize automatic unwinding and recycling of roll materials. Background Technology

[0002] Rolled material refers to materials that are stored by winding various raw materials onto a core. During the use or processing of rolled material, a certain amount of allowance is often reserved to address surface imperfections such as indentations that may occur near the core during storage and transportation. After the rolled material is unwound, this remaining portion remains on the core. From the perspectives of cost-saving and environmental protection, the core and the rolled material wound on it can be recycled for reuse. Currently, the recycling of cores and rolled material typically involves manual removal, specifically manually rotating the core to unwind the rolled material, separating it from the core for recycling. However, the remaining material in the rolled material is often more than 5 meters long, making this manual removal method inefficient, resource-intensive, and costly. US-A-3245302 discloses an apparatus for recovering remaining coils of material wound around a tubular core from a dewinding machine that supplies the material to a rewinder. The apparatus has a mandrel into which the tubular core is inserted, and the remaining coils of material are wound around this mandrel. A blade moving parallel to the axis of the mandrel cuts the coils parallel to the generatrix of the tubular core without cutting the core itself. The tubular core remains engaged with the mandrel, and the coils fall off and are recovered for recycling. While this apparatus solves the problem of manual unwinding during recovery, it requires cutting the material, which presents a high precision requirement: if the cut is too shallow, the material on the tubular core cannot be completely removed; if the cut is too deep, the surface of the tubular core is easily cut, damaging its structure and affecting its lifespan. This critical depth control poses a significant challenge to process stability.

[0003] Therefore, there is an urgent need for a core and roll material recycling device that reduces manual operation, does not damage the core surface, is quick and convenient to recycle, and has high production efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a core and roll material recycling device that reduces manual operation, does not damage the core surface, is quick and convenient to recycle, and has high production efficiency.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A core and roll material recycling device for recycling cores and roll materials wound on cores, comprising:

[0007] The supporting mechanism includes a support base and a support platform disposed on the support base, the support platform being used to support the core and the roll material;

[0008] The unwinding and tightening mechanism includes a core positioning mechanism and a driving mechanism. The core positioning mechanism is located above the support platform and includes a core positioning part for fixing or releasing the core and a roll end fixing part for fixing the end of the roll material. The driving mechanism is mounted on the support mechanism and is drively connected to the core positioning mechanism for driving the core positioning mechanism to rotate.

[0009] The control mechanism includes a controller electrically connected to the drive mechanism of the unwinding and tightening mechanism for adjusting the rotational speed of the drive mechanism and the direction of unwinding and tightening of the roll material.

[0010] The core and roll material recycling device of this application involves placing a roll material with a core onto the core positioning mechanism. The driving mechanism drives the core positioning mechanism to rotate in the opposite direction (opposite to the roll material winding direction) to unwind the roll material. After the core is removed by a robot or manually, the end of the roll material is fixed to the roll material end fixing part. The driving mechanism then drives the core positioning mechanism to rotate in the forward direction (same as the roll material winding direction) to re-tighten the roll material around the core positioning mechanism as the axis, facilitating the removal of the roll material and achieving efficient recycling of the core and roll material.

[0011] As a preferred embodiment of this application, the support base includes a frame and legs supporting the frame. The bottom of the legs is rigidly connected by a cross-shaped connecting frame. This structure can significantly improve the overall torsional stiffness of the support base and achieve multi-directional support within a limited space. The frame, legs, and cross-shaped connecting frame can all be made of angle steel, connected to form a lightweight truss structure.

[0012] As a preferred embodiment of this application, the bearing platform includes a horizontal bearing plane and an annular baffle wall surrounding the outer periphery of the bearing plane and perpendicular to the bearing plane. The annular baffle wall and the bearing plane together define the unwinding and tightening operation space, which can effectively prevent the splashing of debris such as roll material during the unwinding and tightening process and ensure a clean operating environment.

[0013] As a preferred embodiment of this application, the bearing plane is provided with an array of chip removal holes. These chip removal holes penetrate both surfaces of the bearing plane along its thickness direction, forming a directional discharge channel for discharging debris and impurities generated during the unwinding and tightening process. A core coil with the rolled material is positioned outside the core coil positioning mechanism by a robotic arm or manually, perpendicular to the bearing platform. The bearing plane supports the core coil and the bottom of the rolled material. During unwinding and tightening, material debris and dust adhering to the rolled material can fall through the directional discharge channel formed by the chip removal holes due to their own gravity, significantly reducing manual chip removal operations and effectively preventing impurities from accumulating on the bearing plane and contaminating the unwound rolled material, thus affecting its recycling. The annular baffle wall, used in conjunction with the chip removal holes, can significantly improve the working environment. Furthermore, providing chip removal holes on the bearing platform can reduce the overall weight of the equipment, save material costs, and reduce the pressure of the bearing platform on the support base.

[0014] As a preferred embodiment of this application, the core positioning part includes:

[0015] The rotating frame assembly includes a frame body and a rotating shaft. The frame body is coaxially assembled within the unwinding and tightening work space via the rotating shaft, and the end of the rotating shaft is connected to the drive mechanism for transmission.

[0016] A radial positioning mechanism, disposed inside the rotating frame assembly, includes at least one adjustable tensioning part that can move or deform radially along the rotation axis, used to move closer to or away from the inner wall of the core to fix or release the core. The rotating shaft, under the action of the drive mechanism, has two rotational movements in both forward and reverse directions, enabling tightening and unwinding actions. The adjustable tensioning parts can simultaneously extend outward or retract radially along the rotation axis, simultaneously contacting or moving away from the inner wall of the core, thereby fixing or releasing the core. When releasing the core, multiple sets of the adjustable tensioning parts are completely retracted inside the rotating frame assembly. When fixing the core, multiple sets of the adjustable tensioning parts extend at least partially from the rotating frame assembly and simultaneously contact the inner wall of the core, jointly fixing the core. Furthermore, the extension can be flexibly adjusted according to the core's size, allowing for quick adaptation to different models and sizes of cores without replacing any parts. Because the radial positioning mechanism adopts a multi-lobed structure, the core can be stably constrained on the support platform.

[0017] As a preferred embodiment of this application, the frame includes an upper plate and a lower plate that are coaxially opposed, and the two are connected by circumferentially distributed rigid connecting rods to form a cage-like frame structure. The cage-like frame structure is rotatably fitted onto the end of the rotating shaft that extends into the unwinding and tightening working space.

[0018] As a preferred embodiment of this application, the end fixing part of the roll material is, but is not limited to, a slot disposed on the outer edge of the upper platen. There can be one or more slots. When there are multiple slots, each slot is spaced apart circumferentially on the outer edge of the upper platen, and the slot opening faces away from the center of the upper platen. When unwinding is required, the rotating shaft rotates in the reverse direction, causing the roll material to separate from the core, completing the unwinding of the roll material. Then, the core is released and can be removed by a robotic arm or manually. The end of the roll material is then engaged in the slot, and the rotating shaft rotates in the forward direction, causing the frame to rotate in the same direction, thus tightening the roll material. This achieves efficient recycling of the core and the roll material. The entire recycling process does not require unrolling the roll material, saving space, and eliminates the need to cut the roll material, thus avoiding damage to the core surface.

[0019] As a preferred embodiment of this application, the outer diameter of the frame is smaller than the inner diameter of the core, so that when the core is sleeved on the outside of the frame, there is a gap between the two, which makes it easy to remove the core without resistance after unwinding.

[0020] As a preferred embodiment of this application, the rotation axis is perpendicular to the bearing plane.

[0021] Preferably, the adjustable tensioning part is disposed between the upper and lower disc bodies, including an upper positioning ring and a lower positioning ring coaxially sleeved on the rotating shaft. The lower positioning ring is fixedly connected to the lower disc body or the rotating shaft, and the upper positioning ring is slidably engaged with the rotating shaft. At least one linkage mechanism is provided between the upper and lower positioning rings, including two connecting rods. The first ends of the two connecting rods are pivotally connected via a rotating shaft and fitted with a pressure wheel. The second ends of the two connecting rods are respectively hinged to the upper and lower positioning rings. The pressure wheel can be radially extended or retracted by adjusting the distance between the upper and lower positioning rings to fix or release the cylinder core. Preferably, the number of adjustable tensioning parts is 3 to 6, arranged circumferentially at equal intervals, and can extend or retract simultaneously.

[0022] Alternatively, the adjustable tensioning part is an airbag-type inflation / deflation structure set between the upper and lower discs, including a hollow tube and an airbag. The hollow tube is sleeved outside the rotating shaft, and several tensioning blocks connected to the airbag are circumferentially inserted therein. The airbag is set between the hollow tube and the rotating shaft and connected to an air source. Its surface near the inner wall of the hollow tube is connected to the tensioning blocks. The tensioning blocks move closer to or away from the inner wall surface of the cylinder core by inflating and deflating the airbag, thereby fixing or releasing the cylinder core.

[0023] As a preferred embodiment of this application, the airbag is provided with an air inlet and an air outlet. The air inlet of the airbag is connected to the air source through an air inlet pipe, and the air outlet of the airbag is connected to the air extraction device through an air outlet pipe. The air inlet pipe and the air outlet pipe are equipped with control valves, which are electrically connected to the control mechanism. By adjusting the corresponding control valves, the inflation and deflation of the airbag can be controlled, thereby adjusting the position of the tensioning block.

[0024] Preferably, the surface of the tensioning block is arc-shaped. The arc-shaped surface can make surface contact with the inner wall of the core, allowing the core and the tensioning block to fit together better and preventing the core from shaking during unwinding and tightening.

[0025] As a preferred embodiment of this application, the radial positioning mechanism further includes a buffer assembly disposed between the upper positioning ring and the lower positioning ring. The buffer assembly includes a spring sleeved on the rotating shaft and a pressing ring, with the two ends of the spring connected to the lower positioning ring and the pressing ring, respectively. When it is necessary to press the inner wall of the cylinder core, only a downward pressure needs to be applied to the upper positioning ring. At this time, the pressing wheel moves outward until it simultaneously presses the inner wall of the cylinder core, and then the upper positioning ring and the rotating shaft are locked. During the downward movement of the upper positioning ring, it can be slowly lowered by the buffer assembly. The locking between the upper positioning ring and the rotating shaft is achieved by, but not limited to, locking bolts. When it is necessary to release the cylinder core, the locking bolts are loosened, and the upper positioning ring moves upward under the action of the spring, thereby causing the pressing wheel to retract inward during its upward movement.

[0026] As a preferred embodiment of this application, the drive mechanism is a power component such as a bidirectional motor or a servo motor, and its output shaft is connected to the rotating shaft through a gear transmission box; the direction in the same direction as the winding direction of the roll material is defined as the forward direction, and the direction in the opposite direction to the winding direction of the roll material is defined as the reverse direction. When the drive mechanism drives the rotating shaft to rotate in the forward or reverse direction, the rotating frame assembly installed at the end of the rotating shaft rotates synchronously, driving the core positioning mechanism to rotate in the forward or reverse direction, thereby driving the core and the unwound roll material to rotate synchronously to complete the unwinding and tightening actions.

[0027] As a preferred embodiment of this application, the core and roll material recycling device further includes a collection device located below the support platform for collecting impurities discharged through each directional discharge channel.

[0028] As a preferred embodiment of this application, the control mechanism further includes a control switch, and the controller is electrically connected to the control switch and the drive mechanism for controlling the start and stop of the drive mechanism and regulating the direction of power output.

[0029] In use, the core with the rolled material is placed on the frame of the rotating frame assembly. The radial positioning mechanism is adjusted to tighten the inner wall of the core. The drive mechanism is started, causing the frame to rotate the core in the opposite direction, unwinding the material. The drive mechanism is then turned off to stop the rotating shaft. The core is removed by a robot or manually. The end of the material is then locked in the slot. The drive mechanism is turned on again by the control mechanism to rotate the rotating shaft in the forward direction. After the material is tightened again, the drive mechanism is turned off, and the rotating shaft stops rotating. The tightened material is then removed by a robot or manually, completing the recycling of the core and the rolled material.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] 1. It requires little or no manual operation to automatically tighten and unwind the roll material, efficiently remove the roll material from the core, recycle the core and roll material waste, save manpower and resources, reduce production costs, and is environmentally friendly.

[0032] 2. No need to cut or unroll the roll material, it will not damage the surface of the core, takes up little space, and does not affect the service life of the core.

[0033] 3. Unwinding and tightening can be completed simply by rotating the shaft in both directions, making it easy to operate, improving production efficiency, and suitable for large-scale industrial production. Attached Figure Description

[0052] The present application will be further described below with reference to specific embodiments, but the scope of protection of the present application is not limited thereto.

[0053] like Figures 1-7 As shown, the present invention provides a core and roll material recycling device, comprising:

[0054] The supporting mechanism 1 includes a support base 11 and a support platform 12 disposed on the support base 11. The support platform 12 is used to support the core and the roll material wound on the core.

[0055] The unwinding and tightening mechanism 2 includes a core positioning mechanism 21 and a driving mechanism 20. The core positioning mechanism 21 is located above the support platform 12 and includes a core positioning part for fixing or releasing the core and a roll end fixing structure for fixing the roll end. The driving mechanism 20 is mounted on the support mechanism 1 and is drively connected to the core positioning mechanism 21, for driving the core positioning mechanism 21 to rotate.

[0056] The control mechanism 3 is electrically connected to the drive mechanism 20 of the unwinding and tightening mechanism 2, and is used to adjust the rotation speed of the drive mechanism 20 and the direction of unwinding and tightening of the roll material.

[0057] like Figures 1-6 As shown, the support platform 12 includes a horizontal support plane 121 and an annular baffle 122 surrounding the outer periphery of the support plane 121 and perpendicular to the support plane 121. The annular baffle 122 and the support plane together define the unwinding and tightening operation space.

[0058] like Figure 7 As shown, the support base 11 includes a frame 111 and legs 112 supporting the frame. The bottoms of the multiple legs 112 are rigidly connected by a cross-shaped connecting frame 113. This structure can significantly improve the overall torsional stiffness of the support base and achieve multi-directional support within a limited space. The cross-shaped bracket and the column can both be made of angle steel, which are connected to form a lightweight truss structure.

[0059] like Figure 1 and Figure 2 As shown, the bearing plane 121 is distributed with an array of chip removal holes 1211. The chip removal holes 1211 in the array penetrate both surfaces of the bearing plane 121 along the thickness direction to form a directional discharge channel, which is used to discharge debris and impurities during the unwinding and tightening process. The core with the wound material is vertically mounted on the outside of the core positioning mechanism 21 by a robot or manually. The bearing plane 121 supports the bottom of the core. During the unwinding and tightening process, debris, dust and other impurities attached to the material fall from the directional discharge channel formed by the chip removal holes 1211, effectively preventing impurities from accumulating on the bearing plane 121 and contaminating the unwound material, thus affecting the recycling of the material.

[0060] like Figure 1 , Figure 5 and Figure 6 As shown, the core positioning part includes:

[0061] The rotating frame assembly 210 includes a frame body 211 and a rotating shaft 212. The frame body 211 is coaxially mounted in the unwinding and tightening work space via the rotating shaft 212, and the end of the rotating shaft 212 is connected to the drive mechanism 20 for transmission.

[0062] The radial positioning mechanism 220 is disposed inside the rotating frame assembly 210 and includes at least one adjustable tensioning part 221 that can move radially along the rotation axis 212, for moving closer to or away from the inner wall of the core to fix or release the core.

[0063] like Figure 5 As shown, the frame 211 includes an upper plate 2111 and a lower plate 2112 that are coaxially opposed. The two are connected by rigid connecting rods 2113 that are evenly distributed around the circumference to form a cage-like frame structure. The cage-like frame structure is rotatably fitted onto the end of the rotating shaft 212 that extends into the unwinding and tightening working space.

[0064] like Figure 5 As shown, the end fixing structure of the roll material is a slot 2114 disposed on the outer edge of the upper plate 2111. The number of slots can be one or more. When there are multiple slots, each slot is disposed at intervals along the circumferential direction on the outer edge of the upper plate, and the slot opening faces away from the center of the upper plate.

[0065] like Figure 5 and Figure 6 As shown, the adjustable tensioning part 221 is disposed between the upper plate 2111 and the lower plate 2112, and includes an upper positioning ring 2211 and a lower positioning ring 2212 coaxially sleeved on the rotating shaft 212. The lower positioning ring 2212 is fixedly connected to the lower plate 2112 or the rotating shaft 212, and the upper positioning ring 2211 is slidably engaged with the rotating shaft 212. At least two sets of symmetrically distributed linkage mechanisms are provided between the upper positioning ring 2211 and the lower positioning ring 2212. The linkage mechanism includes two connecting rods 2213. The first ends of the two connecting rods 2213 are pivotally connected to and fitted with a pressure wheel 2214 through a rotating shaft. The second ends of the two connecting rods 2213 are respectively hinged to the upper positioning ring 2211 and the lower positioning ring 2212. The pressure wheel 2214 achieves the fixing or release of the cylinder core by adjusting the radial extension and retraction of the distance between the upper positioning ring 2211 and the lower positioning ring 2212.

[0066] like Figure 5 and Figure 6 As shown, the radial positioning mechanism 220 further includes a buffer assembly 222, which is disposed between the upper positioning ring 2211 and the lower positioning ring 2212. The buffer assembly 222 includes a spring 2221 and a pressing ring 2222 sleeved on the rotating shaft 212. The two ends of the spring 2221 are respectively connected to the lower positioning ring 2212 and the pressing ring 2222.

[0067] In some embodiments of this utility model, the adjustable tensioning part 221 includes a hollow tube and an air bladder. The hollow tube is sleeved outside the rotating shaft 212, and several tensioning blocks connected to the air bladder are circumferentially inserted therein. The air bladder is disposed between the hollow tube and the rotating shaft 212 and connected to an air source. Its surface near the inner wall of the hollow tube is connected to the tensioning blocks. The tensioning blocks move closer to or away from the inner wall surface of the core by inflating and deflating the air bladder, thereby fixing or releasing the core.

[0068] In some embodiments of this utility model, the surface of the tensioning block is arc-shaped.

[0069] like Figure 1 , Figure 5 and Figure 7 As shown, the drive mechanism is a power component such as a bidirectional motor or a servo motor, and its output shaft is connected to the rotating shaft through a gear transmission box. The direction that is the same as the winding direction of the roll material is defined as the forward direction, and the direction that is opposite to the winding direction of the roll material is defined as the reverse direction. When the drive mechanism drives the rotating shaft to rotate in the forward or reverse direction, the rotating frame assembly installed at the end of the rotating shaft rotates synchronously, driving the core positioning mechanism to rotate in the forward or reverse direction, thereby driving the core and the unwound roll material to rotate synchronously to complete the unwinding and tightening actions.

[0070] In some embodiments of this utility model, the core and roll material recycling device further includes a collection device located below the support platform, which is used to collect impurities discharged through each directional discharge channel.

[0071] like Figure 1 As shown, the control mechanism 3 also includes a control switch 32. The controller 31 is electrically connected to the control switch 32 and the drive mechanism 22, and is used to control the start and stop of the drive mechanism and adjust the power output direction.

[0072] In use, the core with the rolled material is placed on the frame 211 of the rotating frame assembly 210. The radial positioning mechanism 220 is adjusted to tighten the inner wall of the core. The drive mechanism 22 is started, the core rotates in the reverse direction, and the rolled material is unwound. The drive mechanism 22 is turned off to stop the rotating shaft. The core is removed by a robot or manually. The end of the rolled material is then locked in the slot 2114. The drive mechanism 22 is turned on again by the control mechanism 3 to make the rotating shaft 212 rotate in the forward direction. After the rolled material is tightened again, the drive mechanism 22 is turned off, and the rotating shaft 212 stops rotating. The tightened rolled material is removed by a robot or manually, completing the recycling of the core and the rolled material.

[0073] The above embodiments are for illustrating the implementation schemes disclosed in this utility model and should not be construed as limiting the utility model. Furthermore, various modifications listed herein, as well as variations in the methods and compositions of the utility model, will be apparent to those skilled in the art without departing from the scope and spirit of this utility model. Although this utility model has been specifically described in conjunction with various specific preferred embodiments, it should be understood that this utility model should not be limited to these specific embodiments. In fact, various modifications as described above that are obvious to those skilled in the art to obtain the utility model should be included within the scope of this utility model.
