Description

Technical Field

[0001] The present application relates to the technical field of paper tape production, and in particular to a paper tape storage device. Background Art

[0002] Paper tape is made of kraft paper after surface treatment of log pulp, and then cut into pieces. In the production process of paper tape, the raw material of paper tape needs to be continuously supplied, and the raw material of paper tape is rolled onto the roller. When the paper tape on one roller is consumed, the paper tape on another roller needs to be connected to the end of the paper tape that is about to be consumed. In order to facilitate the connection of the paper tape, the paper tape needs to be in a static state when connected, and the supply of paper tape cannot be interrupted. Therefore, a device is urgently needed to solve the above needs.

[0003] Patent number CN221253468U discloses a flexible paper tape storage device, including a base, on which pillars are symmetrically arranged about its center line, a first support plate and a second support plate are arranged between the two pillars, and the first support plate is slidably arranged between the two pillars, and a first roller and a second roller are respectively distributed on the same side of the first support plate and the second support plate through a rotating shaft, and an extension frame is arranged on the first support plate relative to the first roller. The two pillars are connected by a connecting frame, and a power unit is arranged between the connecting frame and the base, and the power unit cooperates with the extension frame. By lowering the first support plate, the distance between the first support plate and the second support plate is reduced, that is, the paper tape stored between the first support plate and the second support plate is reduced, and by using the excess paper tape for paper tape raw material supply, the paper tape at the feeding end of the storage device is stationary, while the paper tape at the discharging end moves at a uniform speed.

[0004] The defects of the above technical solution are: when the stored material is released, multiple first rollers descend at the same time, which may cause uneven force on the paper tape and make the paper tape loose. Moreover, when the stored material is released, the paper tapes on the storage container all move, which leads to an increase in friction between the paper tape and the first roller and the second roller, thereby increasing energy loss. Summary of the invention

[0005] In order to make the release of paper tape storage smoother and reduce the energy loss caused by friction, the present application provides a paper tape storage device.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A paper tape storage device comprises a support frame, the support frame is connected with a plurality of upper rollers and a plurality of lower rollers, the lower rollers are connected to one side of the support frame, the support frame is connected with a plurality of lifting structures for driving the upper rollers to rise and fall, and each lifting structure corresponds to an upper roller.

[0008] By adopting the above scheme, when the stored material needs to be released, the lifting structure lowers the upper roller in sequence from the discharge end of the accumulator to the feed end, so that the distance between the upper roller and the lower roller is reduced, thereby reducing the paper tape stored between the upper roller and the lower roller for discharging the paper tape, thereby ensuring that the paper tape discharging speed remains unchanged, the feed end of the accumulator stops, and because only one upper roller descends at the same time, only the paper tape close to the descending part of the upper roller moves, thereby reducing the friction between the paper tape and the roller, making the discharge smoother.

[0009] Optionally, the lifting structure includes a threaded rod, which is vertically arranged and rotatably connected to the support frame. The threaded rod is connected to the lifting frame. The lifting frame is provided with a threaded hole, and the threaded rod passes through the threaded hole and is threadedly connected to the lifting frame. The upper roller is rotatably connected to the lifting frame, and the support frame is fixedly connected to a plurality of guide rods, each guide rod corresponds to a lifting frame, and the guide rod passes through the lifting frame and is slidably connected to the lifting frame.

[0010] By adopting the above scheme, the threaded rod rotates to drive the support frame to move up and down, and the guide rod limits the rotation of the support frame, thereby driving the upper roller connected to the support frame to move up and down, thereby changing the length of the paper tape stored between the upper roller and the lower roller.

[0011] Optionally, the threaded rod is fixedly connected to a transmission gear at the upper end, a traveling cylinder is connected above the support frame, and a rack is fixedly connected to one side of the traveling cylinder. When the traveling cylinder moves above the support frame, the rack meshes with multiple transmission gears in sequence.

[0012] By adopting the above scheme, when the paper tape needs to be replaced, the travel cylinder moves from the discharge end of the accumulator to the feed end, so that the rack engages with multiple transmission gears in sequence, thereby driving the threaded rod to rotate in sequence, thereby driving the upper roller to descend in sequence, and releasing the paper tape stored in the accumulator for paper tape production.

[0013] Optionally, the support frame is rotatably connected to a wheel rod, the wheel rod is fixedly connected to a large gear and a small gear, the large gear is meshed with the transmission gear, and when the travel cylinder moves above the support frame, it meshes with multiple small gears in sequence.

[0014] By adopting the above scheme, when the traveling cylinder passes through the threaded rod, the rack meshes with the pinion gear, thereby driving the pinion gear to rotate, thereby driving the large gear to rotate, thereby driving the transmission gear and the threaded rod to rotate, and the small gear and the large gear are set to achieve speed change, thereby increasing the lifting stroke of the lifting structure.

[0015] The cam is provided with a locking plate, the locking plate being arranged on a track which is fixed to the locking plate and is secured on a track with the locking means for locking the locking plate in a manner which allows the locking plate to move relative to the locking plate when the locking plate is engaged.

[0016] By adopting the above scheme, the clamping block abuts against the surface of the threaded rod, thereby limiting the rotation of the threaded rod, thereby avoiding unnecessary rotation of the threaded rod. When the traveling cylinder moves to the position of the threaded rod, the sliding rod slides into the guide groove, thereby driving the sliding rod to move in the direction of compressing the first spring, so that the clamping tube is disengaged from the threaded rod, thereby allowing the threaded rod to rotate, and then the traveling cylinder drives the threaded rod to rotate to realize the lifting and lowering of the upper roller.

[0017] Optionally, the clamping block is in a semicircular arc shape on one side close to the threaded rod for increasing the contact area between the clamping block and the threaded rod.

[0018] By adopting the above solution, the contact area between the clamping block and the threaded rod is increased, so that the clamping block can fix the threaded rod more firmly.

[0019] Optionally, a rubber ring is fixedly connected to the outer side of the threaded rod, the rubber ring is located in the clamping hole, and the clamping block abuts against the outer surface of the rubber ring.

[0020] By adopting the above solution, the friction between the threaded rod and the clamping block is further increased by arranging the rubber ring, and the fixing of the threaded rod by the clamping block is further strengthened.

[0021] Optionally, a buffer hole is opened at the lower position of the support frame, a second spring is connected in the buffer hole, the second spring is fixedly connected to the support frame at the upper end, the second spring is connected to a buffer plate at the lower end, and the lower roller is rotatably connected to the buffer plate.

[0022] By adopting the above solution, when the pulling force at the output end of the accumulator is too large, the paper tape drives the buffer plate to compress the second spring, causing the lower roller to move upward for a distance, thereby avoiding excessive pulling force on the paper tape and causing the paper tape to be damaged.

[0023] Optionally, a vertical guide rod is provided in the buffer hole, the second spring is sleeved on the outside of the guide rod, and the cross section of the guide rod is square. The guide rod passes through the buffer plate and is slidably connected to the buffer plate.

[0024] By adopting the above solution, the buffer plate moves along the guide rod, and the square guide rod limits the rotation of the buffer plate.

[0025] Optionally, the support frame is connected to a switch for stopping the paper tape, and a lever is connected to a buffer plate close to the switch. When the buffer plate moves upward for a certain distance, the lever opens the switch to stop the paper tape feeding.

[0026] By adopting the above scheme, when the pulling force on the paper tape is too large, the paper tape drives the buffer plate to move upward. When the pulling force exceeds a certain value, the lever turns on the switch to stop the device driving the paper tape to move, thereby stopping the paper tape from moving and preventing the paper tape from being broken due to excessive pulling force.

[0027] In summary, this application has the following technical effects:

[0028] 1. By providing a lifting structure for each upper roller, the upper roller can be lifted and lowered individually, so that the paper tape can be discharged more smoothly and the energy loss caused by friction can be reduced;

[0029] 2. By setting up a walking cylinder and a gear, and driving the gear to rotate through the rack, the upper roller can be raised and lowered in sequence;

[0030] 3. By setting up a large gear and a small gear, the lifting stroke of the lifting structure is increased. BRIEF DESCRIPTION OF THE DRAWINGS

When the storage material needs to be released, the lifting structure 4 sequentially lowers the upper rollers 2 from the discharge end of the accumulator close to the feed end, so that the distance between the upper rollers 2 and the lower rollers 3 is reduced, thereby reducing the paper tape stored between the upper rollers 2 and the lower rollers 3, which is used for the discharge of the paper tape, thereby ensuring that the speed of the paper tape discharge remains unchanged, and the feed end of the accumulator stops, and since only one upper roller 2 is lowered at the same time, only the paper tape near the lowered part of the upper roller 2 moves, thereby reducing the friction between the paper tape and the rollers, making the discharge smoother.

[0040] Reference Figure 1 and Figure 2 The lifting structure 4 includes a threaded rod 41, which is vertically arranged and rotatably connected to the support frame 1. The threaded rod 41 is connected to a lifting frame 42, and the lifting frame 42 is provided with a threaded hole.

The rotation of the threaded rod 41 drives the support frame 1 to move up and down, and the guide rod 421 limits the rotation of the support frame 1, thereby driving the upper roller 2 connected to the support frame 1 to move up and down, thereby changing the length of the paper tape stored between the upper roller 2 and the lower roller 3.

[0041] Reference Figure 2 and Figure 3, the threaded rod 41 is fixedly connected with a transmission gear 52 at the upper end, the support frame 1 is connected with a travel cylinder 5, one side of the travel cylinder 5 is fixedly connected with a rack 53, the support frame 1 is rotatably connected with a wheel rod 51, the wheel rod 51 is fixedly connected with a large gear 512 and a small gear 511, the large gear 512 is meshed with the transmission gear 52, when the travel cylinder 5 moves above the support frame 1, the rack 53 is meshed with a plurality of small gears 511 in sequence. When the travel cylinder 5 moves above the support frame 1, the rack 53 is meshed with the small gear 511, thereby driving the small gear 511 to rotate, thereby driving the large gear 512 to rotate, thereby driving the transmission gear 52 and the threaded rod 41 to rotate, so as to realize the upper roller 2 to be lifted and lowered in sequence, by setting the large gear 512 and the small gear 511, the threaded rod 41 can rotate more circles, thereby increasing the lifting stroke of the lifting structure 4.

[0042] Reference Figure 4 and Figure 5 The support frame 1 is connected with a clamping structure 6, and the clamping structure 6 includes a clamping sleeve 61, which is fixedly connected to the support frame 1. A clamping hole 611 is opened at the center of the clamping sleeve 61, and the threaded rod 41 passes through the clamping hole 611. The threaded rod 41 is rotatably connected to the clamping sleeve 61, and a clamping groove 612 is opened on the inner surface of the clamping hole 611. A clamping block 62 is slidably connected in the clamping groove 612. A rubber ring 411 is fixedly connected to the outer side of the threaded rod 41. The rubber ring 411 is located in the clamping hole 611, and the clamping block 62 abuts against the outer surface of the rubber ring 411, and the clamping block 62 is close to the threaded rod 41. The side of the clamping block 62 is in a semicircular arc shape for increasing the contact area between the clamping block 62 and the threaded rod 41, which is used to increase friction, so that the clamping block 62 fixes the threaded rod 41 more firmly. The end of the clamping block 62 facing away from the threaded rod 41 is connected to the first spring 621, and the end of the first spring 621 facing away from the clamping block 62 is fixedly connected to the bottom of the clamping groove 612. A sliding hole 613 is provided on the upper surface of the clamping sleeve 61. The sliding hole 613 is communicated with the clamping groove 612, and a sliding rod 622 is slidably connected in the sliding hole 613. The sliding rod 622 is fixedly connected to the clamping block 62. The sliding hole 613 enables the sliding rod 622 to slide in the direction of compressing or stretching the first spring 621. A guide block 54 is fixedly connected to the lower surface of the walking cylinder 5. A guide groove 541 is provided on the lower surface of the guide block 54. When the guide block 54 moves to the top of the clamping sleeve 61, the sliding rod 622 slides into the guide groove 541, and when the sliding rod 622 slides in the guide groove 541, it moves in the direction of compressing the first spring 621. When the travel cylinder 5 moves to the position of the threaded rod 41, the slide rod 622 slides into the guide groove 541, thereby driving the slide rod 622 to move in the direction of compressing the first spring 621, so that the clamping tube is disengaged from the threaded rod 41, so that the threaded rod 41 can rotate, and then the travel cylinder 5 drives the threaded rod 41 to rotate to realize the lifting and lowering of the upper roller 2.

The second spring 71 is sleeved on the outside of the guide rod 72, and the cross section of the guide rod 72 is square, which limits the rotation of the buffer plate 7. When the tension at the output end of the accumulator is too large, the paper tape drives the buffer plate 7 to compress the second spring 71, so that the lower roller 3 moves upward for a distance, thereby avoiding excessive tension on the paper tape and causing the paper tape to be damaged.

[0044] Reference Figure 6 The support frame 1 is connected with a switch 12 for stopping the paper tape. The switch 12 is connected to the device for driving the paper tape to move through wires. A lever 73 is connected to the buffer plate 7 near the switch 12. When the buffer plate 7 moves upward for a certain distance, the lever 73 opens the switch 12 to stop the paper tape feeding. When the pulling force on the paper tape is too large, the paper tape drives the buffer plate 7 to move upward. When the pulling force exceeds a certain value, the lever 73 opens the switch 12, thereby stopping the paper tape from moving and preventing the paper tape from being broken due to excessive pulling force.

[0045] The specific implementation principle of the present application is as follows: when it is necessary to release the stored material, the travel cylinder 5 moves from the discharge end of the accumulator to the feed end, and the slide rod 622 slides into the guide groove 541, thereby driving the slide rod 622 to move in the direction of compressing the first spring 621, so that the clamping tube is disengaged from the threaded rod 41, so that the threaded rod 41 can rotate, and then the rack 53 is meshed with multiple small gears 511 in turn, and is transmitted to the threaded rod 41 through the large gear 512 and the transmission gear 52, thereby driving the threaded rod 41 to rotate in turn, thereby driving the upper roller 2 to descend in turn, thereby reducing the paper tape stored between the upper roller 2 and the lower roller 3, which is used for the discharge of the paper tape, thereby ensuring that the speed of the paper tape discharge remains unchanged, and the feed end of the accumulator stops, and since only one upper roller 2 descends at the same time, only the paper tape close to the descending part of the upper roller 2 moves, thereby reducing the friction between the paper tape and the roller, making the discharge smoother.
