Description

Technical Field

[0001] The invention relates to the technical field of webbing packaging, and in particular to a large roll packaging device for wide webbing and a packaging method thereof. Background Art

[0002] In the production of webbing, the webbing needs to be rolled and packaged for easy transportation and use.

[0003] After searching, the Chinese patent with publication number: CN109626057A discloses a fully automatic ribbon rolling (cake making) machine. The purpose of the invention is to provide a fully automatic ribbon cake making equipment with simple structure, low cost and high efficiency to replace manual labor. It only needs to simply set the cake making code number to run continuously and automatically to roll the ribbon into a cake plate. The invention uses a control center to programmatically control the ribbon guide metering device, the ribbon quality detection device, the ribbon traction device, the winding mechanism, the ribbon cutting mechanism, and the ribbon cake nailing device to make cakes fully and continuously and automatically form stacks.

[0004] Based on the above search and combined with actual problems, it was found that: the device can only drive the reel to rotate and pull the webbing to be wound on the outside of the reel, but in actual use, the webbing needs to be packaged into small rolls of different diameters. Therefore, the reel frequently stops and rotates. The device is not convenient for packaging the webbing. When the reel stops, the webbing loses its tension and becomes loose. When the reel starts to rotate quickly, the webbing is instantly subjected to a large tension, which is not only easy to break, but also easy to cause uneven arrangement of the webbing wound on the outside of the reel, reducing the accuracy of webbing packaging. Summary of the invention

[0008] Preferably, the energy storage mechanism includes a rotating cylinder rotatably connected to the top end of the inner side of the shell, the rotating cylinder is linearly slidably sleeved on the outer side of the main shaft, and the outer side of the rotating cylinder is rotatably connected to a plurality of sleeve rods, one end of each of the sleeve rods is slidably inserted with a sliding rod, one end of each of the sliding rods is rotatably connected to the inner side of the shell, and the outer end of each sliding rod is elastically connected to the sleeve rod at the corresponding position through a force storage spring.

[0009] Preferably, the one-way locking mechanism comprises a ratchet wheel fixed on the outer side of the rotating shaft at a position close to the cone wheel and a pawl rotatably connected to the outer side of the bracket.

[0010] Preferably, the dispensing tray is rotatably connected to the vertical plate via a winding shaft, a winding motor is installed on one side of the vertical plate, and a driving end of the winding motor is fixedly connected to one end of the winding shaft.

[0011] Preferably, an electric scissors is installed at the middle section of the vertical plate below the traction mechanism.

[0012] Preferably, a limiting rotating rod is rotatably connected to the interior of the vertical plate, one end of the limiting rotating rod is fixed with a stop rod for pressing against the end of the filling plate, and the other end of the limiting rotating rod is fixed with a driving rod, and one side of the vertical plate is rotatably connected to a positioning electric cylinder, and the telescopic end of the positioning electric cylinder is rotatably connected to one end of the driving rod.

[0013] Preferably, the traction mechanism includes a fixed plate fixed on one side of the vertical plate and a power-assisted traction motor installed on the other side of the vertical plate, one end of the fixed plate is rotatably connected to a traction roller, and the other end of the fixed plate is installed with a clamping cylinder, the telescopic end of the clamping cylinder is fixed with a roller bracket, the inner side of the roller bracket is rotatably connected to a clamping roller, and the driving end of the power-assisted traction motor is fixedly connected to one end of the traction roller.

[0015] The present invention also provides a method for packaging large rolls of wide-width ribbon, which specifically comprises the following steps: Step 1: Pass the webbing on the outside of the raw material tray through the webbing outlet to the outside of the stand, and then make the webbing pass through the outlet guide roller, multiple lower guide rollers, multiple upper guide rollers, and an end guide roller in turn, and then pass between the traction roller and the pressing roller of the traction mechanism, and then pass between the two blades of the electric scissors, and finally press the end of the webbing on the outside of the packaging tray; Step 2: During packaging, the winding motor is controlled to drive the winding shaft to rotate, thereby driving the packaging disk to rotate. At the same time, the telescopic end of the abutting cylinder of the traction mechanism extends to drive the roller bracket and the abutting roller to move horizontally, so that the abutting roller presses the webbing against one side of the traction roller. At the same time, the auxiliary traction motor drives the traction roller to rotate. The traction roller pulls the webbing toward the packaging disk through friction. The packaging disk rotates to wind the approaching webbing around its outside. When the webbing of appropriate thickness is wound around the outside of the packaging disk, the two blades of the electric scissors are controlled to merge to cut the webbing, thereby performing separate packaging operations on the webbing. Step 3: When the webbing on the outer side of the packaging disk is wound to a specified thickness, it stops rotating. The raw material disk and the webbing still have a large rotational kinetic energy. When the raw material disk and the webbing rotate, the rotating shaft drives the cone wheel 1 of the energy conversion mechanism to rotate. The cone wheel 1 drives the cone wheel 2 to rotate through friction. The cone wheel 2 drives the main shaft to rotate. The main shaft drives the rotating drum to rotate. The rotating drum drives multiple sleeve rods and multiple sliding rods of the energy storage mechanism to rotate, so that relative sliding occurs between the sleeve rods and the sliding rods connected to each other. The sliding rod slides into the inner side of the sleeve rod and compresses the storage spring. The compression of the multiple storage springs applies a reaction force to the main shaft, thereby forcing the raw material disk and the webbing to stop rotating quickly, thereby converting the kinetic energy of the raw material disk and the webbing into the elastic potential energy of the multiple storage springs for temporary storage. Step 4. When the webbing is wound around the outside of the next packaging disk, the packaging disk rotates again, and the power-assisted traction motor of the winding motor and the traction mechanism is controlled to start, and at the same time, the circuit of the electromagnet in the upper and lower switching mechanism is disconnected, so that the electromagnet is powered off and loses the electromagnetic attraction. Under the action of the lifting spring, the top block and the main shaft are pushed up quickly, so that the cone wheel three is quickly pressed against the cone wheel one, and the cone wheel two is separated from the cone wheel one. At this time, the multiple force storage springs of the energy storage mechanism release the elastic force and push the sliding rod to the outside of the sleeve rod, so that the rotating cylinder is reversed, thereby driving the main shaft to reverse, and the main shaft transmits the rotational torque to the cone wheel three through the one-way bearing, so that the cone wheel three drives the cone wheel one to rotate through the friction force, and the cone wheel one drives the raw material disk and the webbing from static to rotation quickly through the rotating shaft.

[0016] The present invention provides a large roll packaging device and a packaging method for wide-width ribbon by improvement, which has the following improvements and advantages compared with the prior art: First, the present invention can wind a large amount of webbing through the raw material disk, and move the webbing on the outside of the raw material disk by pulling the webbing through the traction mechanism, and drive the filling disk to rotate by the winding motor. The filling disk can wind the webbing pulled close by the traction mechanism on the outside, and finally cut the webbing through electric scissors, thereby realizing the filling operation of webbings of different diameters and specifications, greatly improving the webbing filling efficiency and the accuracy of the filling diameter.

[0017] Secondly: the present invention uses an energy conversion mechanism. After each packaging of the webbing on the outer side of the packaging tray is completed, the raw material tray and the webbing on its outer side can be quickly stopped from rotating, and the rotational kinetic energy can be temporarily stored to prevent the raw material tray and the webbing from continuing to rotate, causing the webbing to loosen and fall off. When the next packaging tray starts to rotate, the energy can be released to make the raw material tray and the webbing quickly rotate from a static state, so that the webbing can be released quickly and evenly, avoiding sliding between the traction mechanism and the webbing, thereby helping to improve the uniformity of the webbing winding on the outer side of the packaging tray, improving the accuracy of the packaging diameter, and avoiding the webbing from being broken due to excessive tension in an instant.

[0031] Embodiment 2: This embodiment also provides a method for packaging large rolls of wide ribbon, which specifically includes the following steps: Step 1: Pass the ribbon on the outside of the raw material tray 8 through the ribbon outlet 305 to the outside and above the stand 1, and then make the ribbon pass through the outlet guide roller 303, multiple lower guide rollers 301, multiple upper guide rollers 302, and an end guide roller 304 in sequence, and then pass between the traction roller 203 and the pressing roller 206 of the traction mechanism, and then pass between the two blades of the electric scissors 9, and finally press the end of the ribbon against the outside of the packaging tray 4; Step 2: During subpackaging, the winding motor 5 is controlled to run and drive the winding shaft 3 to rotate, thereby driving the subpackaging plate 4 to rotate. At the same time, the telescopic end of the tightening cylinder 204 of the traction mechanism extends to drive the roller bracket 205 and the tightening roller 206 to move horizontally, so that the tightening roller 206 presses the ribbon against one side of the traction roller 203. At the same time, the auxiliary traction motor 201 runs to drive the traction roller 203 to rotate. The traction roller 203 pulls the ribbon toward the subpackaging plate 4 through friction. The subpackaging plate 4 rotates to wind the pulled ribbon around its outside. When the outer side of the subpackaging plate 4 is wound with a ribbon of suitable thickness, the two blades of the electric scissors 9 are controlled to merge to cut the ribbon, thereby performing a separate subpackaging operation on the ribbon. Step 3, when the outer webbing of the dispensing plate 4 is wound to a specified thickness, it will stop rotating. The raw material plate 8 and the webbing still have a large rotational kinetic energy. When the raw material plate 8 and the webbing rotate, the cone wheel 101 of the energy conversion mechanism is driven to rotate through the rotating shaft 7. The cone wheel 101 drives the cone wheel 2 104 to rotate through friction. The cone wheel 2 104 drives the main shaft 103 to rotate. The main shaft 103 drives the rotating cylinder 110 to rotate. The rotating cylinder 110 drives the multiple sleeve rods 111 and the multiple sliding rods 112 of the energy storage mechanism to rotate, so that the sleeve rods 111 and the sliding rods 112 connected to each other slide relative to each other. The sliding rod 112 slides into the inner side of the sleeve rod 111 and compresses the storage spring 113. The compression of the multiple storage springs 113 applies a reaction force to the main shaft 103, thereby forcing the raw material plate 8 and the webbing to stop rotating quickly, thereby converting the kinetic energy of the raw material plate 8 and the webbing into the elastic potential energy of the multiple storage springs 113 for temporary storage; When the webbing is wound around the outer side of the next dispensing plate 4, the dispensing plate 4 rotates again, and the winding motor 5 and the auxiliary traction motor 201 of the traction mechanism are controlled to start, and at the same time, the circuit of the electromagnet 107 in the upper and lower switching mechanism is disconnected, so that the electromagnet 107 is powered off and loses the electromagnetic attraction. Under the action of the lifting spring 108, the top block 106 and the main shaft 103 are pushed to move up quickly, so that the cone wheel three 105 is quickly pressed against the cone wheel one 101, and the cone wheel two 104 is separated from the cone wheel one 101. At this time, the multiple force storage springs 113 of the energy storage mechanism release the elastic force, and push the sliding rod 112 to the outside of the sleeve rod 111, so that the rotating cylinder 110 is reversed, thereby driving the main shaft 103 to reverse, and the main shaft 103 transmits the rotational torque to the cone wheel three 105 through the one-way bearing 114, so that the cone wheel three 105 drives the cone wheel one 101 to rotate through the friction force, and the cone wheel one 101 drives the raw material plate 8 and the webbing to rotate quickly from static to rotation through the rotating shaft 7.

[0032] Working principle: when the webbing needs to be packaged, the large roll of webbing wrapped around the outside of the raw material disk 8 is installed and fixed on the outer end of the rotating shaft 7, and the small-sized packaging disk 4 that needs to be packaged is set on the outside of the winding shaft 3, and the telescopic end of the positioning electric cylinder 13 is controlled to retract, and the limit rotating rod 10 is driven to rotate by the driving rod 12, and the limit rotating rod 10 drives the baffle rod 11 to rotate, so that one side of the baffle rod 11 is pressed against one side of the winding shaft 3, and the baffle rod 11 can block the packaging disk 4 to prevent the packaging disk 4 from falling off from the outside of the winding shaft 3, and then the webbing on the outside of the raw material disk 8 is passed through the webbing outlet 305 to the upper outside of the stand 1, and then the webbing is passed around the outlet guide roller 303, multiple lower guide rollers 301, multiple upper guide rollers 302, and an end guide roller 304 in turn, and then passes through the traction roller 203 and the pressing roller 206 of the traction mechanism, and then passes through the electric shear The two blade heads of the knife 9 finally press the end of the webbing against the outer side of the dispensing plate 4. During dispensing, the winding motor 5 is controlled to run and drive the winding shaft 3 to rotate, thereby driving the dispensing plate 4 to rotate. At the same time, the telescopic end of the tightening cylinder 204 of the traction mechanism extends to drive the roller bracket 205 and the tightening roller 206 to move horizontally, so that the tightening roller 206 presses the webbing against one side of the traction roller 203. At the same time, the auxiliary traction motor 201 runs to drive the traction roller 203 to rotate. The traction roller 203 pulls the webbing toward the dispensing plate 4 through friction. The dispensing plate 4 rotates to wind the approaching webbing around its outer side. When the webbing of suitable thickness is wound around the outer side of the dispensing plate 4, the two blade heads of the electric scissors 9 are controlled to merge and cut the webbing, so that the webbing can be packaged separately, thereby greatly improving the packaging efficiency and ensuring the accuracy of the packaging thickness. When the webbing on the outer side of the dispensing plate 4 is wound to a certain thickness, the winding motor 5 and the power-assisted traction motor 201 will stop immediately, so that the dispensing plate 4 and the traction roller 203 will stop rotating. At the same time, the electromagnet 107 of the upper and lower shifting mechanism will be energized to generate electromagnetic attraction to the armature 109, thereby pulling the top block 106 and the main shaft 103 downward. The top block 106 compresses the lifting spring 108, and the main shaft 103 drives the outer cone wheel 2 104 and the cone wheel 3 105 to move downward at the same time, so that the cone wheel 3 105 and the cone wheel 1 105 of the energy conversion mechanism are in contact with each other. 01 is separated, and the second cone wheel 104 is quickly pressed and combined with the first cone wheel 101. After the webbing stops moving, the raw material disc 8 and the webbing wrapped around the outside are still rotating, and the raw material disc 8 and the webbing have a large rotational inertia, so that the raw material disc 8 and the webbing still have a large rotational kinetic energy. When the raw material disc 8 and the webbing rotate, the first cone wheel 101 of the energy conversion mechanism is driven to rotate through the rotating shaft 7. The first cone wheel 101 drives the second cone wheel 104 to rotate through friction, and the second cone wheel 104 drives the main shaft 103 to rotate. The main shaft 103 can rotate in a The main shaft 103 drives the rotating drum 110 to rotate, and the rotating drum 110 drives the multiple sleeve rods 111 and the multiple sliding rods 112 of the energy storage mechanism to rotate, so that the sleeve rods 111 and the sliding rods 112 connected to each other slide relative to each other, and the sliding rods 112 slide into the inner side of the sleeve rods 111 and compress the energy storage springs 113. The compression of the multiple energy storage springs 113 can apply a reaction force to the main shaft 103, thereby forcing the raw material disk 8 and the webbing to stop rotating quickly, thereby The kinetic energy is converted into the elastic potential energy of multiple force storage springs 113 for temporary storage. At the same time, the pawl 117 can prevent the ratchet wheel 116 from rotating in the opposite direction, thereby preventing the rotating shaft 7, the raw material tray 8, the main shaft 103, etc. from rotating in the opposite direction, so that the multiple force storage springs 113 are kept in a compressed state, so that the raw material tray 8 stops rotating quickly, which can well prevent the outer webbing from loosening and falling off, so that when the webbing is wound around the next raw material tray 8, the raw material tray 8 can release the webbing evenly, ensuring the uniformity of the webbing winding on the outer side of the raw material tray 8; When it is necessary to wind the webbing around the next dispensing plate 4, the winding motor 5 and the auxiliary traction motor 201 of the traction mechanism are controlled to start, and at the same time, the circuit of the electromagnet 107 in the upper and lower switching mechanism is disconnected, so that the electromagnet 107 is powered off and loses the electromagnetic attraction. Under the action of the lifting spring 108, the top block 106 and the main shaft 103 are pushed up quickly, so that the cone wheel 3 105 is quickly pressed against the cone wheel 1 101, and the cone wheel 2 104 is separated from the cone wheel 1 101. At this time, the multiple force storage springs 113 of the energy storage mechanism release their elastic force, and the sliding rod 112 is pushed up. The cone wheel 105 is pushed toward the outside of the sleeve rod 111, so that the rotating cylinder 110 is reversed, thereby driving the main shaft 103 to reverse. Since the cone wheel 3 105 is connected to the main shaft 103 in a unidirectional rotation through the one-way bearing 114, the main shaft 103 can transmit the rotation torque to the cone wheel 3 105 through the one-way bearing 114, so that the cone wheel 3 105 drives the cone wheel 1 101 to rotate through the friction force. The cone wheel 101 drives the raw material plate 8 and the webbing to rotate quickly from static to rotation through the rotating shaft 7. The cone wheel 3 105 is driven from the other side of the cone wheel 101. When the main shaft 10 When the cone wheel 3 drives the second cone wheel 104 and the third cone wheel 105 to rotate in the opposite direction, the cone wheel 3 105 can drive the raw material disk 8 and the webbing to continue to rotate in the direction before stopping, thereby ensuring that the recovered energy can continue to drive the raw material disk 8 and the webbing to start rotating in the same direction, so that the raw material disk 8 quickly releases the webbing evenly outward, avoiding the slip between the traction roller 203 of the traction mechanism and the webbing, which affects the winding uniformity of the webbing on the outer side of the dispensing disk 4. Since the cone wheel 3 105 is connected to the main shaft 103 in a unidirectional rotation through the one-way bearing 114, When the raw material disk 8 and the webbing rotate, only the cone wheel three 105 will be driven to rotate, and the rotational torque will not be transmitted to the main shaft 103, so the main shaft 103 will not be driven to rotate. Therefore, after the main shaft 103 transmits energy to the raw material disk 8, the raw material disk 8 and the webbing on its outer side continue to rotate, and the main shaft 103 stops rotating, thereby avoiding the rotation of the raw material disk 8 to affect the main shaft 103. When the raw material disk 8 stops next time, the above principle will make the cone wheel two 104 contact with the cone wheel one 101 again, thereby driving the main shaft 103 to rotate again.

10. A method for packaging large rolls of wide-width ribbon, applied to a device for packaging large rolls of wide-width ribbon as claimed in any one of claims 1 to 9, characterized in that: The specific steps include: Step 1, passing the webbing on the outside of the raw material tray (8) through the webbing outlet (305) to the upper outside of the stand (1), and then passing the webbing around the outlet guide roller (303), multiple lower guide rollers (301), multiple upper guide rollers (302), and an end guide roller (304) in sequence, and then passing between the traction roller (203) and the pressing roller (206) of the traction mechanism, and then passing between the two blades of the electric scissors (9), and finally pressing the end of the webbing against the outside of the packaging tray (4); Step 2: During packaging, the winding motor (5) is controlled to operate to drive the winding shaft (3) to rotate, thereby driving the packaging plate (4) to rotate. At the same time, the telescopic end of the clamping cylinder (204) of the traction mechanism extends to drive the roller bracket (205) and the clamping roller (206) to move horizontally, so that the clamping roller (206) presses the ribbon against one side of the traction roller (203). At the same time, the auxiliary traction motor (201) operates to drive the traction roller (203) to rotate. The traction roller (203) pulls the ribbon toward the packaging plate (4) through friction. The packaging plate (4) rotates to wind the traction-approaching ribbon around its outer side. When the outer side of the packaging plate (4) is wound with a suitable thickness of ribbon, the two blades of the electric scissors (9) are controlled to merge to cut the ribbon, thereby performing a separate packaging operation on the ribbon. Step 3: When the outer webbing of the dispensing tray (4) is wound to a specified thickness, it stops rotating. The raw material tray (8) and the webbing still have a large rotational kinetic energy. When the raw material tray (8) and the webbing rotate, the rotating shaft (7) is driven to rotate. The rotating shaft (7) drives the main shaft (103) of the energy conversion mechanism to rotate. The main shaft (103) drives the multiple sliding rods (112) of the energy storage mechanism to slide into the inner side of the sleeve rod (111) and compress the storage spring (113). The compression of the multiple storage springs (113) exerts a reaction force on the main shaft (103), thereby forcing the raw material tray (8) and the webbing to stop rotating quickly, thereby converting the kinetic energy of the raw material tray (8) and the webbing into the elastic potential energy of the multiple storage springs (113) for temporary storage; Step 4: When the webbing is wound around the outside of the next dispensing plate (4), the dispensing plate (4) rotates again, controls the winding motor (5) and the auxiliary traction motor (201) of the traction mechanism to start, and simultaneously disconnects the circuit of the electromagnet (107) in the upper and lower shifting mechanism. Under the action of the lifting spring (108), the top block (106) and the main shaft (103) are pushed upward rapidly, so that the cone wheel 3 (105) is quickly pressed against the cone wheel 1 (101), and the cone wheel 2 (104) is separated from the cone wheel 1 (101). At this time, the multiple force storage springs (113) of the energy storage mechanism release the elastic force and transmit the elastic force to the main shaft (103), so that it is reversed. The main shaft (103) drives the raw material plate (8) and the webbing to rotate rapidly from rest through the rotating shaft (7).
