Description

Technical Field

[0001] This application relates to the field of machining equipment technology, specifically to material distribution equipment that facilitates unloading. Background Technology

[0002] Currently, material sorting equipment is a type of mechanical processing equipment commonly used for rolling thin and light materials such as paper. Material sorting equipment often drives the sub-rolls sleeved on the outer periphery of the roll to rotate synchronously by driving the roll shaft, so that the material roll on a master roll is re-rolled onto several sub-rolls.

[0003] However, sub-rolls are sometimes placed in the middle of the reel for winding operations. After the sub-roll is wound, it needs to be manually pushed from the middle of the reel towards the edge until it detaches from the reel to complete the unloading operation. It is known that the overall weight of the sub-roll after being wound with a predetermined number of layers is generally quite large, and manually pushing the sub-roll is laborious and time-consuming, resulting in low unloading efficiency.

[0004] In addition, the material distribution equipment sometimes has more than one roll fitted with sub-rolls for the rolling operation, which requires manual unloading of the sub-rolls on each roll separately, which further reduces the overall unloading efficiency. Utility Model Content

[0005] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a material distribution device for easy unloading, used to wind material rolls on a master roll onto several sub-rolls, wherein the material distribution device for easy unloading includes:

[0029] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0030] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] refer to Figures 1 to 2 A preferred embodiment of the material distribution device according to this application will be described in detail below. The material distribution device is used to roll a material roll on a master roll 91 onto a plurality of sub-rolls 92. The material distribution device includes a device body 10, a roll assembly 20, a cutting device 30 and a unloading device 40.

[0033] Specifically, the device body 10 includes a fixed base 11, an unwinding component 12, and a plurality of material transfer components 13. The fixed base 11 extends horizontally from one end to the other to form a material transfer channel 1101. The unwinding component 12 includes an unwinding shaft 121 and at least one unwinding drive unit 122. The unwinding shaft 121 is rotatably connected to the fixed base 11 and located at the port of the material transfer channel 1101, and the mother roll 91 is sleeved on the middle of the unwinding shaft 121. The unwinding drive unit 122 is rotatably connected to the unwinding shaft 121 so that the mother roll 91 rotates synchronously with the unwinding shaft 121 and is unwound.

[0034] In one embodiment, the number of unwinding drive units 122 is set to two, and the two ends of the unwinding shaft 121 are rotatably connected to the two unwinding drive units 122 respectively. Thus, when it is necessary to unwind the master roll 91, the two unwinding drive units 122 can be activated simultaneously to easily drive the master roll 91 to rotate for unwinding operation.

[0035] Each of the material transfer components 13 includes a material transfer shaft 131 and a material transfer drive unit 132. Each material transfer shaft 131 is rotatably connected to the material transfer channel 1101 of the fixed base 11 and is axially parallel to the unwinding shaft 121. Adjacent material transfer shafts 131 are also axially parallel to each other. Furthermore, a plurality of material transfer shafts 131 are evenly and spaced apart along the extension direction of the material transfer channel 1101. One material transfer drive unit 132 is rotatably connected to one material transfer shaft 131 to stably transfer the material roll on the master roll 91 by the material transfer shaft 131.

[0036] It should be noted that the cutting device 30 is used to cut the material rolls being transported on the sub-rolls 92 into different sizes along a direction perpendicular to the axis of the parent roll 91, so that the winding assembly 20 can roll material rolls of different lengths on each sub-roll 92.

[0037] Thus, the unwinding drive unit 122 is activated to drive the unwinding shaft 121 to rotate, causing the master roll 91 to be unwound as it rotates with the unwinding shaft 121. Simultaneously, the material transfer drive unit 132 is activated to drive the corresponding material transfer shaft 131 to rotate, causing the unwound material roll on the master roll 91 to be transferred by the rotating material transfer shaft 131 to the position of the winding assembly 20, thereby allowing the winding assembly 20 to wind the material roll into the sub-roll 92.

[0038] Preferably, the unwinding drive units 122 are all mounted on the fixed base 11, and each of the unwinding drive units 122 is configured as a drive motor with a speed reduction function.

[0039] Preferably, each of the material transfer and driving units 132 is configured as a drive motor.

[0040] The roll assembly 20 includes at least one roll spool 21 and the same number of drive members 22 as the roll spool 21. One end of each roll spool 21 is rotatably connected to the fixed base 11 and is located at the other end of the material transfer channel 1101 away from the unwinding shaft 121. Each roll spool 21 is axially parallel to any one of the material transfer shafts 131 for the sub-roll 92 to be fitted onto. That is, all the material transfer shafts 131 are held between the unwinding shaft 121 and the roll spool 21 so that when the master roll 91 is unwound, the material roll is transported along the extension direction of the material transfer channel 1101 to the position of the roll spool 21 by the transmission action of the material transfer shafts 131.

[0041] In addition, one of the drive members 22 is rotatably connected to one end of the roll shaft 21.

[0042] Understandably, when the drive member 22 is activated to drive the corresponding roll shaft 21 to rotate, the unwinding drive unit 122 is activated to drive the unwind shaft 121 to rotate, so that the master roll 91 is unwound. At the same time, each material transfer drive unit 132 is also activated to drive the corresponding material transfer shaft 131 to rotate, so that the material roll unwound from the master roll 91 is transferred to the roll shaft 21, thereby performing the operation of winding the sub-roll 92.

[0043] It is worth noting that one end of each of the roll spools 21 connected to the fixing base 11 is stably supported by the fixing base 11 to support the rotating roll spool 21 in driving the sub-roll 92 to rotate for winding operations. In addition, each of the roll spools 21 can also be used to directly wind rolls of the same width as the roll on the master roll 91.

[0044] Preferably, a plurality of positioning portions 211 are evenly provided on the outer periphery of each of the said roll spools 21. The positioning portions 211 on each of the said roll spools 21 are configured to extend along the axial direction of the roll spool 21, so as to circumferentially hold the sub-roll 92 when it is sleeved on the roll spool 21, specifically as follows: Figure 3 and Figure 10 As shown, each of the roll shafts 21 positions the sleeved sub-roll 92 through the positioning part 211, so that each sub-roll 92 rotates synchronously with the roll shaft 21 to complete the rolling operation.

[0045] In addition, after the material roll is formed on the sub-roll 92, the unloading device 40 is used to push the formed sub-roll 92 along the axial direction of the corresponding roll shaft 21 from the end near the drive member 22 to the end away from the drive member 22 until the sub-roll 92 is disengaged from the corresponding roll shaft 21.

[0046] In a preferred embodiment, such as Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 11 As shown, the number of the roll spools 21 is set to two, and the two roll spools 21 are respectively held at the top and bottom of the fixed base 11, and the two roll spools 21 are also kept axially parallel. Correspondingly, the number of the driving members 22 is also set to two, and the two driving members 22 are set at the same side of the fixed base 11 to drive the two roll spools 21 to rotate respectively.

[0047] It is understood that both of the material rolls 21 are used to roll the same material roll 91 onto the sub-roll 92. Compared to using a single material roll 21 for the rolling operation, using two material rolls 21 for the rolling operation at the same time can speed up the number of sub-rolls 92 that are rolled, thereby improving the rolling efficiency.

[0048] Preferably, each of the driving components 22 is configured as a driving motor.

[0049] In one example, the cutting device 30 includes a plurality of cutters, which are disposed in the material transfer channel 1101 and located on the moving path of the winding shaft 21 for winding the material roll. Thus, when the material roll on the master roll 91 is wound, at least one of the cutters is used to directly cut the material roll of the master roll 91 into at least two parts.

[0050] In another example, the cutting device 30 includes an adjusting unit 31 and a plurality of cutting components 32. The adjusting unit 31 is connected to the material transfer channel 1101 of the fixed base 11, and the adjusting unit 31 has a guide portion 311 extending parallel to the axial direction of the material transfer shaft 131 and a plurality of moving portions 312 movable within the guide portion 311. One of the cutting components 32 is movably disposed on one of the moving portions 312 of the adjusting unit 31 along the extending direction of the guide portion 311 to cut the material roll transmitted by the material transfer shaft 131 at different positions, so that the material roll is cut to a predetermined rolling width and rolled by the rolling assembly 20.

[0051] In other words, the positioning unit 31 can drive each of the cutting components 32 to move to a predetermined cutting position through the moving part 312 to cut the material roll.

[0052] Preferably, the adjustment unit 31 is configured as a rodless cylinder, and the guide portion 311 of the adjustment unit 31 is configured as the guide rail of the rodless cylinder, and each of the moving portions 312 of the adjustment unit 31 is configured as the slider of the rodless cylinder.

[0053] Each of the cutting components 32 includes a telescopic member 321, a rotating unit 322, and a cutting blade 323. One of the telescopic members 321 is connected to a moving part 312 of the positioning unit 31, and multiple telescopic members 321 are spaced apart from and opposite to the same material transfer shaft 131, and are all located on the same side of the material transfer shaft 131 in the direction of transporting the material roll. That is, the material roll that the master roll 91 is unwound can be transported between the telescopic member 321 and the material transfer shaft 131.

[0054] Furthermore, each of the telescopic members 321 also has a telescopic extension portion to move closer to and further away from the same material transfer shaft 131. A belt-driven unit 322 is connected to the telescopic extension portion of one of the telescopic members 321. A cutter 323 is synchronously rotatably connected to one of the belt-driven units 322, and the axial direction of each cutter 323 remains parallel to the axial direction of the material transfer shaft 131.

[0055] It is understood that when each of the telescopic components 321 is activated to bring the telescopic part closer to the material transfer shaft 131, the corresponding belt-driven unit 322 and the cutter 323 are synchronously driven to approach the material transfer shaft 131 until the cutter 323 abuts against the material roll being transported by the material transfer shaft 131. At this time, the belt-driven unit 322 is activated to drive the corresponding cutter 323 to rotate so that the material roll is cut.

[0056] Thus, when the conveyed roll needs to be cut to a predetermined width, the adjusting unit 31 drives the corresponding moving part 312 to move, so that the corresponding cutting assembly 32 is moved to the predetermined cutting position to cut the roll. It is worth mentioning that during this process, the telescopic member 321 can drive the telescopic part away from the conveyor shaft 131, so that the cutter 323 moves synchronously with the telescopic part away from the conveyor shaft 131, preventing the cutter 323 from scraping the roll and causing damage.

[0057] Preferably, each of the telescopic members 321 is configured as a telescopic cylinder, and the telescopic portion of each of the telescopic members 321 is configured as the telescopic end of the telescopic cylinder.

[0058] Preferably, each of the drive unit 322 is configured as a motor.

[0059] Furthermore, the cutting device 30 also includes two suction components 33, which are used to collect the rough edges formed on both sides of the cutting roll.

[0060] It should be noted that two of the cutting components 32 move along with the two moving parts 312 of the positioning unit 31 and are located at both ends of the guide part 311 to cut the two sides of the material roll.

[0061] Preferably, the suction assembly 33 includes two receivers 331 and two suction members 332, wherein the two receivers 331 are symmetrically arranged on both sides of the material transfer channel 1101, and the two receivers 331 are separately connected to the fixing base 11. Furthermore, each receiver 331 has an inlet 33101 and a receiving chamber 33102 communicating with the inlet 33101, wherein the two inlets 33101 of the two receivers 331 face opposite sides of the material roll transport direction. One suction member 332 communicates with the receiving chamber 33102 of one receiver 331, and each suction member 332 is configured to create a negative pressure at the inlet 33101 of the corresponding receiver 331 to guide the cut burrs through the inlet 33101 and into the corresponding receiving chamber 33102.

[0062] In this way, the burrs cut off on both sides of the roll can be sucked into the interior of the two take-up units 331 by the two suction members 332 respectively, thereby avoiding the burrs from interfering with the operation of other equipment.

[0063] Preferably, each of the suction components 332 is configured as a negative pressure pump.

[0064] Specifically, specifically as Figure 6 and Figure 7 As shown, the unloading device 40 includes an unloading drive unit 41 and a movable block 42, wherein the unloading drive unit 41 is disposed on the fixed base 11 of the device body 10. The movable block 42 is disposed outside the material transfer channel 1101 and close to each of the rolls 21, and one side of the movable block 42 extends toward each of the rolls 21 until the movable block 42 and each of the sub-rolls 92 at least partially overlap in their projections about the axial direction of the rolls 21, and the movable block 42 is moved in a direction parallel to the axial direction of each of the rolls 21 by being driven by the unloading drive unit 41, for pushing the sub-rolls 92 on each of the rolls 21.

[0065] Those skilled in the art will understand that when the sub-roll 92 on each of the winding shafts 21 of the winding assembly 20 completes the winding operation, the unloading drive unit 41 is activated to drive the movable block 42 to move axially along each of the winding shafts 21 until at least a portion of the movable block 42 abuts against the sub-roll 92 on each of the winding shafts 21. At this time, the sub-roll 92 on each of the winding shafts 21 is pushed toward the other end away from the drive member 22 until it is completely disengaged from the winding shaft 21.

[0066] In this way, the unloading device 40 automatically pushes the completed sub-roll 92 towards one end of each of the winding spools 21, replacing manual labor, until the sub-roll 92 is completely detached from each of the winding spools 21. During this process, the efficiency of unloading the sub-roll 92 is improved due to reduced manual intervention. Furthermore, when more than one winding spool 21 is used for winding operations, the unloading device 40 can also simultaneously unload the completed sub-roll 92 from each winding spool 21 by driving the movable block 42, further improving the efficiency of unloading the sub-roll 92.

[0067] In one embodiment, the unloading drive unit 41 is configured as a telescopic device, wherein the telescopic device is connected to the fixed base 11 of the equipment body 10, and the telescopic device has a telescopic end, and the telescopic device is configured to move in a direction parallel to the moving direction of the movable block 42. The movable block 42 is connected to the telescopic end of the telescopic device, so that when the telescopic device is activated to drive the telescopic end to move, the movable block 42 is driven to move synchronously with the telescopic end of the telescopic device in a predetermined direction to push the sub-roll 92 on each of the roll shafts 21.

[0068] It is worth mentioning that, in this embodiment, the telescopic device includes, but is not limited to, a telescopic cylinder.

[0069] In another embodiment, the unloading drive unit 41 includes an unloading drive component 411 and a transmission component 412, wherein the transmission component 412 is disposed on the fixed base 11 of the device body 10, and the transmission component 412 is driven by the unloading drive component 411 to rotate and drive the movable block 42 to move, thereby causing the movable block 42 to move in a predetermined movement manner for pushing the sub-roll 92 of each of the roll shafts 21.

[0070] Preferably, the transmission component 412 includes a connecting frame 4121, a drive screw 4122, and at least one guide rail 4123. The unloading drive component 411 is connected to the connecting frame 4121, and the connecting frame 4121 is connected to the top of the fixed base 11 of the equipment body 10 and spans across the material transfer channel 1101. The drive screw 4122 is synchronously rotatably connected to the unloading drive component 411, and the drive screw 4122 is threadedly connected to the movable block 42. The bottom of the connecting frame 4121 is connected to one of the guide rails 4123, and each guide rail 4123 is arranged to extend from one side of the material transfer channel 1101 to the other side of the material transfer channel 1101 in a direction parallel to the moving direction of the movable block 42. The movable block 42 is movably connected to each guide rail 4123 so that its moving direction is restricted by the guide rail 4123.

[0071] Understandably, when the unloading drive 411 is activated, the drive screw 4122 is driven to rotate. Since the movable block 42 is restricted in its direction of movement by at least one of the guide rails 4123, the movable block 42 moves along the extension direction of each of the guide rails 4123 to push the sub-roll 92 on each of the roll shafts 21.

[0072] Preferably, the unloading drive 411 is configured as a drive motor.

[0073] It is worth mentioning that, in a preferred embodiment, such as Figure 6 and Figure 7 As shown, the number of guide rails 4123 is set to two, and the two guide rails 4123 are connected to the top and bottom of the connecting frame 4121 respectively in a manner that keeps them axially parallel. One of the guide rails 4123 is connected to the bottom of the connecting frame 4121, and the other guide rail 4123 is also connected to the fixed base 11. That is to say, in this embodiment, the movable block 42 is restricted in its direction of movement by both guide rails 4123, thereby enabling the movable block 42 to move more stably in a predetermined manner, thus preventing deviation.

[0074] Furthermore, the unloading device 40 also includes at least one pusher plate 43. Preferably, each pusher plate 43 is disposed on the side of the movable block 42 near the roll spool 21, and one pusher plate 43 is opposite to one roll spool 21. Each pusher plate 43 has a recessed notch 4301 on its side near one roll spool 21, and one notch 4301 is used to receive one roll spool 21. In addition, the projections of each pusher plate 43 and the movable block 42 about the axial direction of the same roll spool 21 only partially overlap. That is, when the unloading drive unit 41 drives the movable block 42 to move, one roll spool 21 moves relative to the notch 4301 of one pusher plate 43. At this time, the sub-roll 92 on each roll spool 21 is pushed not only by the movable block 42, but also by the pusher plate 43.

[0075] In other words, when pushing the sub-roll 92 on the roll 21, the area of ​​the sub-roll 92 being abutted increases, so that the sub-roll 92 is pushed more stably.

[0076] Preferably, such as Figures 6 to 8 As shown, the pusher plate 43 generally has a fan-shaped structure.

[0077] More preferably, the projected area of ​​the pusher plate 43 about the axial direction of the roll shaft 21 is not less than the projected area of ​​the entire sub-roll 92 about the axial direction of the roll shaft 21. In this way, the sub-roll 92 can be pushed while maintaining the flatness of the roll after it is rolled.

[0078] It should be added that the end of each of the winding shafts 21 away from the drive member 22 is used to maintain docking with the docking shaft of a docking device. That is, the unloading device 40 can push the entire sub-roll 92 that has completed the winding operation from the winding shaft 21 onto the docking shaft of the docking device, thereby completing the unloading operation.

[0079] Preferably, the cross-sectional size of the notch 4301 of each pusher plate 43 is set to be larger than the cross-sectional size of a corresponding roll 21 and smaller than the cross-sectional size of the inner ring of the sub-roll 92, so as to completely accommodate a roll 21.

[0080] Furthermore, the unloading device 40 also includes at least one adjusting member 44, which is used to push one of the pusher plates 43 toward a corresponding roll spool 21 until the notch 4301 of each pusher plate 43 completely accommodates a roll spool 21, thereby increasing the contact area between each pusher plate 43 and the sub-roll 92 on the corresponding roll spool 21, so that the sub-roll 92 on each roll spool 21 is pushed more stably after the winding operation is completed.

[0081] Preferably, each of the adjusting members 44 includes an adjusting drive member 441 and a driving block 442, wherein each adjusting drive member 441 is connected to the movable block 42, and one adjusting drive member 441 is drivably connected to one driving block 442. A pusher plate 43 is detachably connected to the end of one driving block 442 away from the adjusting drive member 441, so that when one adjusting drive member 441 drives one driving block 442, the corresponding pusher plate 43 is driven to move relatively closer to and away from one of the roll shafts 21.

[0082] Understandably, when the movable block 42 needs to be driven to unload the sub-roll 92 that has completed the winding operation on each of the roll spools 21, each of the adjusting drive members 441 is activated to drive a drive block 442 connected to each of the adjusting drive members 441 to move, so that a corresponding pusher plate 43 is synchronously driven to move toward a roll spool 21 until the notch 4301 of the pusher plate 43 completely receives a roll spool 21. In this way, the sub-roll 92 can be more stably pushed away from the roll spool 21 after winding a roll of any thickness.

[0083] Preferably, each of the adjusting members 44 is configured as a telescopic device, such as a telescopic cylinder, to drive the pusher plate 43 close to the winding shaft 21.

[0084] Furthermore, the material distribution device for easy unloading also includes a support component 50, which supports the other end of each of the material rolls 21 away from the drive member 22, thereby driving each of the material rolls 21 to rotate more stably, and at the same time reducing the load pressure on each of the material rolls 21.

[0085] Specifically, in one example, the support assembly 50 includes at least one support drive unit 51 and the same number of support arms 52 as the support drive unit 51, wherein each support arm 52 forms a first end 521 and a second end 522 opposite to the first end 521 at both ends, and the first end 521 of one support arm 52 is driven by the support drive unit 51 to rotate and drive the second end 522 closer to one of the roll spools 21, and one support arm 52 is correspondingly disposed below one of the roll spools 21, and in a cross section perpendicular to the axial direction of the roll spool 21, the distance between the axis of each roll spool 21 and the rotation center formed by the rotation of the corresponding support arm 52 is not greater than the distance between the second end 522 of the corresponding support arm 52 and the rotation center formed by the rotation of the corresponding support arm 52.

[0086] It is understood that when the support drive unit 51 is activated to drive the corresponding support arm 52 to rotate, since in the cross section perpendicular to the axial direction of the roll spool 21, the distance between the axis of each roll spool 21 and the rotation center formed by the rotation of the corresponding support arm 52 is not greater than the distance between the second end 522 of the corresponding support arm 52 and the rotation center formed by the rotation of the corresponding support arm 52, that is, at least a portion of a roll spool 21 is located on the rotation path of the corresponding support arm 52, at this time, the second end 522 of a support arm 52 is driven and rotates toward the corresponding roll spool 21 until the second end 522 abuts against the other end of the corresponding roll spool 21 away from the drive member 22, thereby supporting the other end of the roll spool 21 away from the drive member 22.

[0087] Thus, when the overall weight of the sub-roll 92 used for rolling the material roll on each of the roll spools 21 increases, each of the roll spools 21 can be supported more stably because its two ends are supported by the fixing seat 11 and a corresponding support arm 52, respectively.

[0088] It should be added that before the unloading device 40 unloads the sub-roll 92 from the roll 21, the support assembly 50 supports the other end of the corresponding roll 21 away from the drive member 22 through each support arm 52 until the docking shaft of the docking device docks with the other end of each roll 21 away from the drive member 22. At this time, one of the support drive units 51 drives the corresponding support arm 52 to rotate so that the second end 522 of the corresponding support arm 52 moves away from the corresponding roll 21 until the axial projection of the support arm 52 about the corresponding roll 21 is offset from the axial projection of the corresponding pusher plate 43 and the sub-roll 92 about the roll 21. This allows the support arm 52 to avoid and move away from the path of the corresponding pusher plate 43 that pushes the sub-roll 92, thereby enabling the driven pusher plate 43 to push the sub-roll 92 from the other end of the roll 21 away from the drive member 22 to the docking shaft of the docking device in a predetermined manner.

[0089] It is worth mentioning that before the pusher plate 43 pushes the sub-roll 92, the docking shaft of the docking device first maintains a docking state with one end of the roll spool 21 near the support arm 52. The support arm 52 then avoids the pusher plate 43 pushing the sub-roll 92. During this process, the docking device can replace the support arm 52 in supporting the roll spool 21 by maintaining a docking state with one end of the roll spool 21 until the sub-roll 92 is completely transferred to the docking shaft of the docking device. At this time, the support arm 52 gradually returns to its original position and supports the end of the roll spool 21 that is docked with the docking device.

[0090] In one embodiment, each of the support drive units 51 is fixedly connected to the fixed base 11, and each of the support drive units 51 is rotatably connected to the first end 521 of a corresponding support arm 52. It is understood that in this embodiment, each of the support drive units 51 is configured as a motor with a locking function.

[0091] In another embodiment, each of the support drive units 51 includes a support drive member 511 and a linkage member 512, wherein each support drive member 511 is hinged to the fixed base 11, and each support drive member 511 has a retractable adjustable end for driving the linkage member 512. One linkage member 512, driven by one of the support drive members 511, causes one support arm 52 to rotate about its first end 521 as a rotation center, so that the second end 522 of the support arm 52 approaches one of the roll shafts 21. The first end 521 of each support arm 52 is hinged to the fixed base 11.

[0092] Preferably, specifically as follows Figure 11 As shown, each linkage component 512 includes a first linkage rod 5121 and a second linkage rod 5122. One end of the first linkage rod 5121 is hinged to the fixed base 11 of the device body 10, and the other end of the first linkage rod 5121 is hinged to one end of the second linkage rod 5122, so that the first linkage rod 5121 and the second linkage rod 5122 form a variable included angle. The other end of the second linkage rod 5122, away from the first linkage rod 5121, is hinged to a corresponding support arm 52 and close to the first end 521 of the corresponding support arm 52. In addition, one of the first linkage rods 5121 is also hinged to the adjusting end of a support drive member 511.

[0093] It should be noted that when the support drive member 511 is activated to extend or retract the moving end of the support drive member 511, the corresponding first linkage rod 5121 is driven to rotate around the hinge point between itself and the fixed seat 11 as the rotation center, so that the included angle formed between the first linkage rod 5121 and the second linkage rod 5122 gradually increases and decreases.

[0094] As the included angle formed between the first linkage rod 5121 and the second linkage rod 5122 in each linkage component 512 gradually increases, the distance between the hinge point of the first linkage rod 5121 and the fixed seat 11 and the hinge point of the second linkage rod 5122 and the corresponding support arm 52 gradually increases. At this time, the support arm 52 is supported by the first linkage rod 5121 and the second linkage rod 5122 and rotates around the hinge point with the fixed seat 11 as the rotation center until it abuts against the corresponding coil shaft 21; and when each linkage component As the included angle between the first linkage rod 5121 and the second linkage rod 5122 in 512 gradually decreases, the distance between the hinge point of the first linkage rod 5121 and the fixed seat 11 and the hinge point of the second linkage rod 5122 and the corresponding support arm 52 gradually decreases. At this time, the support arm 52 rotates around the hinge point with the fixed seat 11 as the rotation center and gradually moves away from the corresponding roll shaft 21 until the support arm 52 avoids the push plate 43 and the sub-roll 92 on the roll shaft 21 corresponding to the unloading device 40.

[0095] Preferably, the hinge position of each first linkage rod 5121 and the corresponding support drive member 511 is set close to the hinge position of the first linkage rod 5121 and the second linkage rod 5122. According to the lever principle, when the vertical distance between the line of action of the driving force applied to the first linkage rod 5121 and the hinge position of the first linkage rod 5121 and the fixed seat 11 increases, the driving force of the support drive member 511 to drive the corresponding first linkage rod 5121 to rotate will decrease, thereby facilitating the driving of the first linkage rod 5121.

[0096] Preferably, each of the support drive members 511 is configured as a telescopic device, such as a telescopic cylinder.

[0097] Preferably, each support arm 52 also has a limiting notch 5201 formed at the second end 522, and the size of each limiting notch 5201 is set to perfectly fit the size of the corresponding roll spool 21. Furthermore, in a cross-section perpendicular to the axial direction of the roll spool 21, the distance between the center of the limiting notch 5201 of each support arm 52 and the rotation center formed by the rotation of the support arm 52 is equal to the distance between the axis of the corresponding roll spool 21 and the rotation center formed by the rotation of the support arm 52.

[0098] Understandably, when one of the support drive units 51 drives the corresponding support arm 52 to rotate to abut against the corresponding roll spool 21, the other end of the corresponding roll spool 21 away from the drive member 22 is gradually completely received by the limiting notch 5201 of the corresponding support arm 52. At this time, the other end of the corresponding roll spool 21 away from the drive member 22 is blocked by the inner wall forming the limiting notch 5201 and is limited.

[0099] In a preferred embodiment, specifically as follows: Figure 11 As shown, the number of the rolls 21 is set to two, and the two rolls 21 are respectively close to the top and bottom of the fixed base 11 and keep axially parallel. The support assembly 50 includes a support drive unit 51, a pair of support arms 52 and a connecting rod 53, wherein each support arm 52 forms a first end 521 and a second end 522 opposite to the first end 521 at both ends, and the first end 521 of one support arm 52 is driven by the support drive unit 51 to rotate and drive the second end 522 to approach one of the rolls 21, and one support arm 52 is correspondingly arranged below one of the rolls 21, and in a cross section perpendicular to the axial direction of the roll 21, the distance between the axis of each roll 21 and the rotation center formed by the rotation of the corresponding support arm 52 is not greater than the distance between the second end 522 of the corresponding support arm 52 and the rotation center formed by the rotation of the corresponding support arm 52.

[0100] The two ends of the connecting rod 53 are respectively hinged to the second ends 522 of the two support arms 52. Thus, when the support drive unit 51 drives one of the corresponding support arms 52 to rotate, the connecting rod 53 causes the two support arms 52 to be driven synchronously to move closer to and further away from their respective corresponding roll shafts 21, thereby ensuring that the two support arms 52 can be driven stably.

[0101] Furthermore, the support assembly 50 also includes the same number of limiting members 54 as the support arm 52, one of the limiting members 54 being used to stably limit one of the roll shafts 21 by a corresponding support arm 52.

[0102] Preferably, such as Figure 10As shown, each of the limiting members 54 includes a telescopic member 541 and a limiting block 542, wherein one of the telescopic members 541 is connected to a support arm 52 near the limiting notch 5201. A limiting block 542 is movably connected to a telescopic member 541 and is driven by a telescopic member 541 to close and open a limiting notch 5201. When a spool 21 is received in the limiting notch 5201 of a corresponding support arm 52, the corresponding telescopic member 541 is activated to drive the limiting block 542 to move in a predetermined manner until the limiting notch 5201 is completely closed. At this point, the limiting block 542 is completely positioned on the path of the corresponding spool 21 disengaging from the limiting notch 5201, thereby stably confining the corresponding spool 21 within the limiting notch 5201.

[0103] It should be noted that each of the roll spools 21 is provided with a bearing at the other end away from the drive member 22, for being received in a corresponding limiting notch 5201. Thus, when the corresponding limiting block 542 completely closes the limiting notch 5201, the corresponding roll spool 21 can be easily driven to rotate by a drive member 22 through the bearing.

[0104] Furthermore, the facilitating unloading of the roll also includes at least one pressing component 60, one of which is used to adjust the tightness of the roll being wound when the roll is wound onto at least one of the sub-rolls 92 by one of the roll shafts 21.

[0105] As an example, specifically as follows Figure 11As shown, each pressing assembly 60 includes two pressing drive units 61, two pressing arms 62, and a pressing roller 63. The two pressing drive units 61 are symmetrically arranged on both sides of the material transfer channel 1101, and both pressing drive units 61 are hinged to the fixed base 11 of the equipment body 10. The two pressing arms 62 are also symmetrically arranged on both sides of the material transfer channel 1101 and are both hinged to the fixed base 11. An assembly space 601 communicating with the material transfer channel 1101 is formed between the two pressing arms 62 for material roll movement. In addition, the driving end of one pressing drive unit 61 is hinged to one pressing arm 62, and the two pressing arms 62 are configured to be driven by the two pressing drive units 61 respectively to synchronously carry the pressing roller 63 to rotate. Each of the pressure rollers 63 is rotatably disposed in the assembly space 601 in a manner that keeps axially parallel to one of the roll shafts 21 and is located on the same side of the roll being wound by the sub-roll 92. In a cross section perpendicular to the roll shaft 21, the distance between the midpoint of the roll shaft 21 and the rotation center formed by the rotation of the pressure arm 62 is equal to the distance between the center of the pressure roller 63 and the rotation center formed by the rotation of the pressure arm 62.

[0106] It is understood that the material roll on the master roll 91 is transferred and located between the roll shaft 21 and the pressure roller 63. When the two pressure drive units 61 are activated, the two pressure arms 62 are driven synchronously to carry the corresponding pressure roller 63 to rotate until the pressure roller 63 approaches and moves away from the corresponding roll shaft 21.

[0107] In this way, when it is necessary to increase the tightness of the material roll on the sub-roll 92, the two pressing drive units 61 drive the corresponding two pressing arms 62 to rotate, so that one pressing roller 63 is driven to press the material roll against each of the sub-rolls 92 on the corresponding winding shaft 21, so that each rotating sub-roll 92 is wound.

[0108] Preferably, the pressing drive unit 61 is configured as a telescopic device, such as a telescopic cylinder.

[0109] Preferably, each of the pressing arms 62 further has a limiting channel 6201 communicating with the assembly space 601, and the two limiting channels 6201 are held at the same horizontal height relative to each other. Furthermore, in one embodiment, each pressing assembly 60 further includes a pressure-relieving member 64. Preferably, each pressure-relieving member 64 includes two sliding blocks 641 and two elastic members 642, wherein the two sliding blocks 641 are movably connected to the limiting channels 6201 of the two pressing arms 62 in a snap-fit ​​manner, and the pressure roller 63 is rotatably connected to the two sliding blocks 641. The two elastic members 642 are vertically disposed in the two limiting channels 6201 in a compressible manner along the axial direction, and the two elastic members 642 are also held at the same horizontal height relative to each other. The two ends of each elastic member 642 are respectively connected to the sliding block 641 and the inner wall forming the limiting channel 6201.

[0110] It should be added that when the pressure roller 63 is driven to press the roll against the winding shaft 21, that is, when the pressure roller 63 indirectly abuts against each of the sub-rolls 92 on the winding shaft 21 by pressing against the roll, the elastic element 642 is compressed by the movement of the sliding block 641 in each of the pressure-relieving members 64, thereby buffering the pressure of the pressure roller 63 on each of the sub-rolls 92.

[0111] More preferably, such as Figure 5 As shown, each of the pressure-relieving components 64 further includes a limiting post 643. One of the limiting posts 643 is disposed in a limiting channel 6201 through one of the elastic members 642, and one end of the limiting post 643 is connected to a sliding block 641. The other end of the limiting post 643 away from the sliding block 641 is disposed through the inner wall forming the limiting channel 6201 until it is at least partially located outside the pressure arm 62. The limiting post 643 of each of the pressure-relieving components 64 is axially parallel to the elastic member 642.

[0112] It is understood that one of the limiting posts 643 is used to limit the compression mode of one of the elastic elements 642. Thus, when the sliding block 641 is driven to compress the corresponding elastic element 642, the corresponding elastic element 642 is gradually compressed, and the corresponding limiting post 643 moves synchronously with the sliding block 641, thereby increasing the portion of the other end of the limiting post 643 that extends out of the pressure arm 62 away from the sliding block 641.

[0113] Preferably, each of the elastic elements 642 is configured as a set of springs.

[0114] More preferably, the pressing assembly 60 further includes at least one feed roller 65, wherein each feed roller 65 is disposed in the assembly space 601, and each feed roller 65 is rotatably connected between the two pressing arms 62 for rolling contact with the conveyed roll.

[0115] In a preferred embodiment, such as Figure 11 As shown, the number of the rolls 21 is set to two, and the two rolls 21 are respectively held at the top and bottom of the fixing base 11 and kept axially parallel. Correspondingly, the number of the pressing assemblies 60 is set to two, which are used to press against the corresponding rolls wound by the sub-rolls 92 wound on the two rolls 21, so that the sub-rolls 92 on each roll 21 can tightly wind the rolls.

[0116] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
