Description

Technical Field

[0001] The invention belongs to the field of seal paper anti-deviation, and in particular relates to a seal paper anti-deviation system and device. Background Art

[0002] During the production process of stamp paper, the unrolled stamp paper often has the problem of deviation. If the deviated stamp paper is not corrected in time, it will cause the stamp paper to be entangled with the machine, conveying deviation and paper breakage during the process of being guided out from the transmission roller. In addition, as the paper roll is continuously unwound, the number of turns of the paper roll will continue to decrease. When the number of turns of the paper roll decreases, the tension between the end of the stamp paper output from the paper roll roller and the transmission roller will change, which will cause the stamp paper to be unable to remain taut when passing through the transmission roller, and the stamp paper will easily deviate and be entangled with the machine during transportation.

[0013] A seal paper anti-deviation system, used in seal paper anti-deviation devices:

[0014] Tension adaptive adjustment process:

[0015] Step 1: During the unwinding process of the stamp paper roll, the number of turns of the stamp paper roll will continue to decrease. The contact roller is always in contact with the bottom of the stamp paper roll under the cooperation of the main slide bar, the telescopic rod and the compression spring 1. The main slide bar slides in the vertical direction under the action of the limit clamp. The main slide bar drives the swing seat and the auxiliary guide rod to deflect synchronously through the main guide rod under the cooperation of the main guide block and the main guide groove;

[0016] Step 2: During the deflection process, the auxiliary guide rod drives the auxiliary slide rod to slide vertically downward along the auxiliary sleeve through the cooperation of the auxiliary guide groove and the auxiliary guide block. During the downward sliding process of the auxiliary slide rod, the adjusting roller installed on its top will move downward synchronously. The downward sliding of the adjusting roller will pull the seal paper, thereby adjusting the tension between the seal paper and the roller and the adjusting roller, so that the seal paper roll roller always keeps the seal paper taut during the unwinding process;

[0017] Correction process:

[0018] Step 1: After the seal paper contacts the guide roller 1, the thrust generated will drive the sliding seat to move in the direction of the seal paper offset. During the sliding process of the sliding seat, the driving arm 1 provided at the bottom of the sliding seat will be driven to move synchronously. The rotating plate will deflect under the cooperation of the protrusion and the driving groove 1.

[0019] Step 2: The driving arm 2 drives the rotating seat to deflect under the cooperation of the driving groove 2 and the protrusion. The guide roller 2 set on the top of the rotating seat continuously corrects the offset seal paper until the offset seal paper returns to the correct track and moves.

[0020] The present invention has the following beneficial effects:

[0021] When the present invention is in use, the abutment roller is always in contact with the bottom of the seal paper roll roller under the mutual cooperation of multiple structures such as the main slide bar, the telescopic rod and the compression spring, so that the abutment roller can sense the change of the number of turns of the seal paper roll roller in real time. As the number of turns of the seal paper roll roller decreases, the main slide bar moves vertically upward under the limit of the limit clamp. During the rising process, the main slide bar drives the swing seat to deflect through the cooperation of the main guide block and the main guide groove opened by the main guide rod. The deflection of the swing seat will then drive the secondary guide rod on the other side to deflect, and the secondary guide rod drives the secondary slide bar to slide downward, thereby causing the adjusting roller to drive the seal paper to move downward a certain distance. By adjusting the distance between the two rollers and the adjusting roller, the tension of the seal paper between the roller and the adjusting roller can be adjusted, so that the seal paper always remains taut and not loose during the transportation process, effectively avoiding the problem of insufficient tension of the seal paper caused by the continuous reduction of the number of turns of the seal paper roll roller during the transportation process.

[0022] When the present invention is in use, the thrust generated after the seal paper contacts the guide roller 1 will drive the sliding seat to move in the direction of the seal paper offset, and the driving arm rod 1 drives the rotating plate to deflect through the cooperation of the protrusion and the driving groove 1. The driving arm rod 2 drives the rotating seat to deflect under the cooperation of the rotating plate, the driving groove 2 and the protrusion, so that the guide roller 2 can continuously correct and fine-tune the offset seal paper and the normally transported seal paper, thereby avoiding the problem of the existing seal paper easily running off during the production and transportation process.

DETAILED DESCRIPTION

[0031] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1-6 As shown in the figure, as the paper roll is continuously unwound, the number of turns of the paper roll will continue to decrease. When the number of turns of the paper roll decreases, the tension between the end of the paper roll output from the paper roll roller and the transmission roller will change. If the tension between the end of the paper roll output from the paper roll roller and the transmission roller cannot be adjusted at all times during the process of reducing the number of turns of the paper roll, the paper roll will be entangled with the machine, the conveying will be offset, and the paper will break when it is guided out from the transmission roller. To solve this problem, the specific operations are as follows:

[0034] A device for preventing stamp paper from deflecting comprises a frame 1, a carrier 201 being installed inside the frame 1, a stamp paper roll 202 being installed inside the carrier 201, multiple groups of rollers 203 being installed inside the carrier 201, and both ends of the rollers 203 being movably connected to the frame 1 via bearings, a correction component 3 being installed inside the frame 1, a tension adaptive component 4 being provided at the bottom of the stamp paper roll 202, two ends of a rotating shaft 401 being movably connected to the inner side wall of the frame 1 via bearings, a swing seat 402 being fixedly sleeved on the outer side of the rotating shaft 401, a main guide rod 403 and a secondary guide rod 404 being fixedly connected on both sides of the swing seat 402, and a main sleeve 405 and a secondary sleeve 406 being fixedly installed at the bottom of the inner wall of the frame 1;

[0035] The main sleeve 405 and the auxiliary sleeve 406 are respectively slidably connected with the main slide bar 407 and the auxiliary slide bar 408. The bottom end of the main slide bar 407 and the bottom inner wall of the main sleeve 405 and the bottom end of the auxiliary slide bar 408 and the auxiliary sleeve 406 are fixedly connected with a telescopic rod 414. The outer side of the telescopic rod 414 is sleeved with a compression spring 1. The top of the main slide bar 407 is connected to the abutment roller 415 through the support 1, and the top of the auxiliary slide bar 408 is connected to the adjustment roller 409 through the support 2. The outer sides of the main guide rod 403 and the auxiliary guide rod 404 are respectively provided with a main guide groove 410 and an auxiliary guide groove 411. One side of the main slide bar 407 and the auxiliary slide bar 408 are respectively movably connected with a main guide block 412 and an auxiliary guide block 413 through a bearing. The two groups of main slide bars 407 and the auxiliary slide bars 408 are fixedly connected with a connecting rod 7. The paper roll 202 is unwound through multiple rollers 203, and the number of turns of the seal paper roll roller 202 will continue to decrease during the unwinding process. The reduction in the number of turns of the seal paper roll roller 202 will drive the main slide bar 407 to gradually rise under the dual cooperation of the compression spring 1 and the telescopic rod 414, thereby ensuring that the contact roller 415 is always in contact with the seal paper roll roller 202. The main slide bar 407 moves vertically upward under the limit of the limit clamp 8. During the rising process, the main slide bar 407 drives the swing seat 402 to deflect through the cooperation of the main guide block 412 and the main guide groove 410 opened by the main guide rod 403. The deflection of the swing seat 402 will drive the secondary guide rod 404 on the other side to deflect, and the secondary guide rod 404 drives the secondary slide bar 408 to slide downward on the secondary sleeve 406 through the mutual cooperation of the secondary guide groove 411 and the secondary guide block 413 and gradually squeezes the telescopic rod 414 and the compression spring 1;

[0036] like Figure 5 and Figure 6 As shown, Figures 5 to 6 This is a schematic diagram of the process in which the adjusting roller 409 gradually descends and pulls the paper unwound by the seal paper roll roller 202. By adjusting the distance between the two rollers 203 and the adjusting roller 409, the tension of the seal paper between the roller 203 and the adjusting roller 409 is adjusted, so that the seal paper always remains taut and not loose during the conveying process, effectively avoiding the problem of insufficient tension of the seal paper caused by the continuous reduction in the number of turns of the seal paper roll roller 202 during the conveying process.

[0037] Example 2

[0038] like Figure 1 and Figure 4 As shown in the figure, since the paper will deviate during the conveying process, if the deviated paper is not adjusted in time, it will affect its normal winding, and even cause the paper to be entangled with the machine or the paper to break. To solve this problem, the specific operations are as follows:

[0039] A slide groove 302 is provided at the top of the slide rail 301. A slider is slidably connected to the slide rail 301. A sliding seat 303 is fixedly connected to the top of the slider. A driving arm 304 is fixedly connected to the bottom of the slider. An electric push rod 305 and a limit slide frame 306 are symmetrically mounted on the top of the slide seat 303. A slide plate 307 is slidably connected to the limit slide frame 306. One end of the electric push rod 305 is fixedly connected to the slide plate 307. The top of the slide plate 307 is fixedly connected to a support frame 308. A guide roller 309 is movably connected to the support frame 308 via a bearing.

[0040] The electric push rod 305 pushes the slide plate 307 to slide horizontally along the limit slide frame 306. The movement of the slide plate 307 drives its top to move synchronously through the support frame 308 and the guide roller 309. By symmetrically fixedly connecting two electric push rods 305 to the top of the sliding seat 303, the electric push rod 305 adjusts the distance between the two guide rollers 309, thereby enabling the device to transport seal paper materials of different widths.

[0041] The inner side wall of the frame 1 is fixedly connected to a horizontal plate 101, and the top of the horizontal plate 101 is movably connected to a rotating plate 310 through a bearing. The top of the rotating plate 310 is movably connected to two protrusions 311 through a bearing. The top of the driving arm 304 is provided with a driving groove 312 that cooperates with the protrusion 311. The inner side wall of the frame 1 is also fixedly connected to a horizontal plate 2 102, and the top of the horizontal plate 2 102 is movably connected to a rotating rod through a bearing. The top of the rotating rod is fixedly connected to a rotating seat 313, and the outer side of the circumference of the rotating rod is fixedly connected to a driving arm 2 314. The top of the driving arm 2 314 is provided with a driving groove 2 315 that cooperates with the protrusion 311.

[0042] like Figure 1 As shown, when the seal paper deviates to the right, it first contacts the guide roller 1 309 on the right and drives the guide roller 1 309 to rotate. At the same time, the sliding seat 303 is pushed to the right by the seal paper deviating to the right and slides to the right synchronously. During the sliding process of the sliding seat 303 to the right, the driving arm 1 304 connected to the bottom through the slider is driven to move to the right synchronously. The top of the driving arm 1 304 is provided with a driving groove 1 312 that matches the protrusion 311. The rotating plate 310 is connected to the protrusion 311 and the driving groove 1 The driving arm 2 314 cooperates with the driving slot 2 315 and the protrusion 311 to drive the rotating seat 313 to deflect clockwise. The top of the rotating seat 313 is fixedly connected with multiple groups of supporting frames 2 316. The supporting frames 2 316 are movably connected with guide rollers 2 317 through bearings. The guide rollers 2 317 continuously correct the offset seal paper in cooperation with the deflected rotating seat 313 until the offset seal paper returns to the correct track and moves.

[0043] Example 3

[0044] During the transportation process, the stamp paper will generate a lot of static electricity with the transmission roller. If this static electricity is not eliminated in time, the paper will be deflected due to the static electricity. To solve this problem, a horizontal plate 3 103 is fixedly connected to the inner wall of the frame 1, and an electric push rod 2 5 is fixedly connected to the bottom of the horizontal plate 3 103. An electrostatic eliminator 6 is installed at the bottom end of the electric push rod 2 5. With the cooperation of the electric push rod 2 5, the electrostatic eliminator 6 can always be in contact with the stamp paper, thereby eliminating the static electricity on the surface of the stamp paper, effectively avoiding the problem of the stamp paper being deflected due to static electricity.
