Description

Technical Field

[0001] The present application relates to the technical field of papermaking, and in particular to an automatic paper tail pasting system for a paper roll rewinder. Background Art

[0002] The rewinder sequentially rewinds the base paper rolls produced by the papermaking machine, producing finished paper for shipment. After the rewinder rewinds the finished paper roll, the unloading platform rises to rest against the rewinder's front bottom roller. A paper pusher then pushes the paper roll from the rewinder's bottom roller onto the unloading platform. Once the paper roll enters the unloading platform, the platform begins to descend. Once the platform reaches the center limit, double-sided tape is manually applied to secure the paper tail to the roll. Manually attaching the paper tail to the roll is time-consuming and labor-intensive, with a low degree of automation and inefficient attaching efficiency. Utility Model Content

[0003] In view of the above problems, the present application provides an automatic paper tail pasting system for a paper roll rewinder, which solves the problem that after the existing rewinder rolls the paper, it pushes the paper roll onto the paper unloading platform, and then needs to manually paste the paper tail onto the paper roll, which is time-consuming, labor-intensive and has a low degree of automation.

[0004] To achieve the above-mentioned purpose, the inventor provides a paper roll rewinding machine automatic paper tail pasting system, comprising:

[0005] a paper unloading platform, the paper unloading platform being used to receive the paper roll unloaded from the rewinder;

[0006] A glue spraying mechanism, wherein a glue spraying head of the glue spraying mechanism is arranged above the paper unloading platform through a gantry, and the glue spraying head is aimed at the paper roll on the paper unloading platform at a preset angle;

[0007] A paper pressing roller, which is movably arranged on the paper unloading platform and is used to drive the paper tail to rise and press it on the paper roll;

[0008] The driving mechanism is used to drive the paper pressing roller to press on the surface of the paper roll and move upward.

[0009] In some embodiments, the preset angle is 75 degrees diagonally upward from the paper roll.

[0010] In some embodiments, the driving mechanism comprises:

[0011] a first drive motor, the first drive motor being arranged on one side of the paper unloading platform;

[0012] a first telescopic transmission mechanism, one end of which is connected to the output shaft of the first drive motor, and the other end of which is connected to one end of the paper pressing roller via a bearing;

[0013] a second driving mechanism, the second driving mechanism being arranged on the other side of the paper unloading platform;

[0014] A second telescopic transmission mechanism, one end of the second telescopic transmission mechanism is connected to the output shaft of the second drive motor, and the other end of the second telescopic transmission mechanism is connected to the other end of the paper pressing roller through a bearing.

[0015] In some embodiments, the first telescopic transmission mechanism includes:

[0016] a first connecting rod, one end of which is connected to the first driving motor;

[0017] a second connecting rod, one end of which is telescopically arranged at the other end of the first connecting rod, and the other end of the second connecting rod is movably connected to one end of the paper pressing roller via a bearing;

[0018] a first elastic member, one end of the first elastic member being disposed on the first connecting rod, the other end of the first elastic member being disposed on the second connecting rod, and the first elastic member being used to provide a pulling force for the second connecting rod toward the first connecting rod;

[0019] The second telescopic transmission mechanism comprises:

[0020] a third connecting rod, one end of which is connected to the second driving motor;

[0021] a fourth connecting rod, one end of which is telescopically arranged at the other end of the third connecting rod, and the other end of the fourth connecting rod is movably connected to the other end of the paper pressing roller via a bearing;

[0022] A second elastic member, one end of the second elastic member is arranged on the third connecting rod, the other end of the second elastic member is arranged on the fourth connecting rod, and the second elastic member is used to provide a pulling force for the fourth connecting rod in the direction of the third connecting rod.

[0023] In some embodiments, the first elastic member and the second elastic member are both springs.

After the paper roll enters the paper unloading platform, the paper unloading platform begins to descend. After the paper unloading platform descends to the middle limit position, the glue spraying mechanism starts to work, and the glue with high viscosity and low fluidity is sprayed onto the paper roll of the paper unloading platform at a preset angle through the glue spraying head. Then the driving mechanism drives the paper pressing roller to rise along the outer surface of the paper roll and press on the paper roll, and the paper pressing roller rises with the paper tail and presses on the paper roll, completing the work of pasting the paper tail on the paper roll, realizing the pasting of the paper roll, improving the automation of the production, and improving the pasting efficiency of the paper roll.

[0065] See also Figure 1-2 This embodiment provides a paper rewinding machine automatic paper tail pasting system, including:

[0066] A paper unloading platform 110, wherein the paper unloading platform 110 is used to receive the paper roll 200 unloaded from the rewinder;

[0067] The glue spraying mechanism includes a glue head 121 positioned above the paper unloading platform 110 via a gantry 150. The glue head 121 is aligned at a preset angle with the paper roll 200 on the unloading platform 110. The glue spraying mechanism utilizes a pneumatic glue sprayer, comprising a solenoid valve, a glue head 121, a glue tank 122, and a delivery pipeline. The solenoid valve controls the opening and closing of the glue head 121 by controlling air pressure, thereby controlling the application of glue. The glue head 121 has a spray hole 510 for evenly spraying glue onto the surface of the object to be glued. The glue tank 122 is a pressure barrel that stores glue and delivers it to the glue head 121 via a delivery pipeline. The delivery pipeline connects the glue tank 122 and the glue head 121 to ensure smooth glue flow. During operation, the solenoid valve controls the flow of compressed air, allowing glue to flow from the glue tank 122 through the delivery pipeline into the glue head 121. Through the spray hole 510 , the glue is evenly sprayed on the surface of the object to be glued.

[0068] A paper pressing roller 130 , which is movably disposed on the paper unloading platform 110 and is used to drive the paper tail to rise and press it on the paper roll 200;

[0069] The driving mechanism is used to drive the paper pressing roller 130 to press on the surface of the paper roll 200 and move upward.

[0070] After the paper roll 200 is unloaded, the paper unloading platform 110 starts to move downwards. After the paper roll 200 is unloaded, the paper unloading platform 110 starts to move downwards. After the paper unloading platform 110 moves downwards to the middle limit position, the glue spraying mechanism starts to work and sprays glue with high viscosity and low fluidity onto the paper roll 200 on the unloading platform 110 at a preset angle through the glue spraying head 121. Then, the driving mechanism drives the pressing roller 130 to move upwards along the outer surface of the paper roll 200 and press on the paper roll 200. The pressing roller 130 moves upwards with the paper tail and presses on the paper roll 200, completing the work of pasting the paper tail on the paper roll 200, thereby realizing the pasting of the paper roll 200, improving the automation of the production, and improving the pasting efficiency of the paper roll 200.

[0071] In some embodiments, the preset angle is 75 degrees diagonally above the paper roll 200. By positioning the glue spray head 121 at a position 75 degrees diagonally above the paper roll 200, the glue spray head 121 can spray glue at the optimal location on the paper roll 200 for adhesion. In other embodiments, other preset angles can also be used as the spray angle of the glue spray head 121.

[0072] In some embodiments, the driving mechanism comprises:

[0073] A first driving motor 141 , which is disposed on one side of the paper unloading platform 110 ;

[0074] A first telescopic transmission mechanism 143, one end of which is connected to the output shaft of the first drive motor 141, and the other end of which is connected to one end of the paper pressing roller 130 via a bearing;

[0075] A second driving mechanism, the second driving mechanism is arranged on the other side of the paper unloading platform 110;

[0076] The second telescopic transmission mechanism has one end connected to the output shaft of the second drive motor 142 , and the other end connected to the other end of the paper pressing roller 130 via a bearing.

[0077] The two ends of the paper pressing roller 130 are driven by the first drive motor 141 and the second drive motor 142 respectively. When the paper pressing roller 130 needs to press on the paper roll 200 and rise, the first drive motor 141 and the second drive motor 142 work synchronously and rotate upward through the first telescopic transmission mechanism 143 and the second telescopic transmission mechanism respectively, thereby driving the paper pressing roller 130 to move upward along the outside of the paper roll 200. The first telescopic transmission mechanism 143 and the second telescopic transmission mechanism are both telescopic. As the paper pressing roller 130 rises upward on the outer surface of the paper roll 200, the length of the first telescopic transmission mechanism 143 and the second telescopic transmission mechanism changes as the distance between the paper pressing roller 130 and the motor changes. The two ends of the paper pressing roller 130 are respectively set on the first telescopic transmission mechanism 143 and the second telescopic transmission mechanism through bearings. The paper pressing roller 130 can rotate as it moves on the outside of the paper roll 200, so that the paper pressing roller 130 can rise more smoothly on the outside of the paper roll 200.

[0078] See also Figure 3-4 In some embodiments, the first telescopic transmission mechanism 143 includes:

[0079] A first connecting rod 310, one end of which is connected to the first driving motor 141;

[0080] A second connecting rod 320, one end of which is telescopically disposed at the other end of the first connecting rod 310, and the other end of the second connecting rod 320 is movably connected to one end of the paper pressing roller 130 via a bearing;

[0081] a first elastic member 330, one end of the first elastic member 330 being disposed on the first connecting rod 310, and the other end of the first elastic member 330 being disposed on the second connecting rod 320, the first elastic member 330 being configured to provide a pulling force for the second connecting rod 320 toward the first connecting rod 310;

[0082] The second telescopic transmission mechanism comprises:

[0083] A third connecting rod 410, one end of which is connected to the second driving motor 142;

[0084] a fourth connecting rod 420, one end of which is telescopically disposed at the other end of the third connecting rod 410, and the other end of the fourth connecting rod 420 is movably connected to the other end of the paper pressing roller 130 via a bearing;

[0085] The second elastic member 430 has one end disposed on the third connecting rod 410 , and the other end disposed on the fourth connecting rod 420 . The second elastic member 430 is configured to provide a pulling force for the fourth connecting rod 420 toward the third connecting rod 410 .

[0086] The first connecting rod 310, the first elastic member 330 and the second connecting rod 320 form a first telescopic transmission mechanism 143, and the third connecting rod 410, the third elastic member and the second connecting rod 320 form a second telescopic transmission mechanism. When the first drive motor 141 and the second drive motor 142 synchronously drive the paper pressing roller 130 to move upward on the outer surface of the paper roll 200, the second connecting rod 320 of the first telescopic transmission mechanism 143 is stretched outward, and the fourth connecting rod 420 of the second telescopic transmission mechanism is stretched outward, so that the lengths of the first telescopic transmission mechanism 143 and the second telescopic transmission mechanism change as the paper pressing roller 130 rises. At the same time, the first elastic member 330 exerts a pulling force on the second connecting rod 320 and the second elastic member 430 exerts a force on the fourth connecting rod 420, so that the paper pressing roller 130 is firmly pressed against the paper roll 200. As the paper pressing roller 130 rises, the pressure of the paper pressing roller 130 on the paper roll 200 increases, so that the paper tail can be firmly attached to the paper roll 200.

[0087] In some embodiments, both the first elastic member 330 and the second elastic member 430 can be springs. The springs can generate a pulling force for the second connecting rod 320 toward the first connecting rod 310, and for the fourth connecting rod 420 toward the third connecting rod 410. This increases the surface pressure of the pressing roller 130 on the paper roll 200 during its ascent, allowing the paper tail to adhere more effectively to the paper roll 200. In other embodiments, the first elastic member 330 and the second elastic member 430 can be other elastic members, such as elastic rubber strips.

[0088] See also Figure 3-4 In some embodiments, the other end of the first connecting rod 310 is provided with a first sliding groove 311, and one end of the second connecting rod 320 is slidably disposed on the first sliding groove 311;

[0089] The other end of the third connecting rod 410 is provided with a second sliding groove 411 , and one end of the fourth connecting rod 420 is slidably disposed on the second sliding groove 411 .

[0090] By providing a first sliding groove 311 at one end of the first link 310 and a second sliding groove 411 at one end of the third link 410, and the second link 320 being slidably disposed in the first sliding groove 311, the second link 320 and the first link 310 can be relatively telescopic, and the fourth link 420 is slidably disposed in the second sliding groove 411, so that the fourth link 420 and the third link 410 can be relatively telescopic, thereby ensuring the telescopic performance of the first telescopic transmission mechanism 143 and the second telescopic transmission mechanism. In other embodiments, the other ends of the first link 310 and the third link 410 can be tubular, and the second link 320 is disposed in the other end of the first link 310 via the first elastic member 330, and the fourth link 420 is disposed in the other end of the third link 410 via the second elastic member 430, so that the relative telescopic between the first link 310 and the second link 320 and the relative telescopic between the third link 410 and the fourth link 420 can be achieved. Other methods may also be used to achieve the telescopic connection between the first link 310 and the second link 320 and the telescopic connection between the third link 410 and the fourth link 420 .

[0091] In some embodiments, a proximity switch is further included, and the proximity switch is disposed on the paper unloading platform 110. By disposing the proximity switch in the middle of the paper unloading platform 110, the proximity switch is used to detect whether the paper roll 200 is on the paper unloading platform 110, thereby triggering the next action. For example, when the proximity switch detects that the paper pusher has pushed the paper roll 200 onto the paper unloading platform 110, the paper unloading platform 110 is triggered to descend. After the paper unloading platform 110 descends to the middle limit position, the paper tail of the paper roll 200 is glued.

[0092] See also Figure 5 In some embodiments, the glue spray head 121 is a tubular glue spray head with a spray hole 510 radially disposed therein, aligned at a preset angle with the paper roll 200 on the paper unloading platform 110. By employing a tubular glue spray head and providing multiple spray holes 510 therein, glue can be evenly sprayed onto the paper roll 200. In other embodiments, a rectangular opening radially disposed therein, aligned at a preset angle with the paper roll 200 on the paper unloading platform 110, can also be provided. Alternatively, multiple glue spray heads 121 can be provided to spray glue onto the paper roll 200.

[0093] In some embodiments, a system for automatically gluing paper tails on a paper roll rewinder is provided. After the rewinder finishes winding the paper, the unloading platform 110 rises and leans against the front bottom roller. The paper pusher pushes the paper roll 200 from the rewinder bottom roller into the unloading platform 110. After the paper roll 200 enters the unloading platform 110, it presses against a proximity switch for detecting the paper roll 200 in the middle of the unloading platform 110. The unloading platform 110 begins to descend. After descending to the middle limit, the glue spraying head 121 installed on the gantry 150 above the unloading platform 110 sprays high-viscosity and low-fluidity glue at an angle of 75 degrees above the paper roll 200. The glue spraying action is achieved by controlling the compressed air with an electromagnetic valve to spray the glue out. Then, the pressure roller 130 installed at the end of the unloading platform 110 rises with the paper tail and presses on the paper roll 200 to complete the action of gluing the paper roll 200. The press roller 130 is driven by motors at both ends. It is movable and rotatable, and its ascending trajectory forms an arc around the paper roll 200. As the ascending height increases, the pressure of the press roller 130 on the paper surface increases, achieving adhesion of the paper roll 200. This improves production automation and reduces labor costs.

[0094] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
