Description

Technical Field

[0001] This invention relates to an electrostatic adsorption copier paper processing equipment and a winding method, which is applied in the field of copier paper processing equipment. Background Technology

[0002] This equipment, with manufacturing application number 202021203648.6, is used for a type of copy paper. While existing equipment operates relatively stably, ribbon wrinkling frequently occurs at the start of winding. The current winding device uses a motor-driven air shaft, with a receiving drum mounted on it. The air shaft inflates to engage the receiving drum for winding. A drawback of the current device is that both the winding and unwinding mechanisms are controlled by independent motors. This can lead to a significant speed difference between the winding drum and the base material drum during operation. Since the composite copy paper is electrostatically bonded without adhesives, this speed difference can cause wrinkling of the ribbon within the bonded paper, reducing product yield. Figure 1-2 As shown, the problem of wrinkled ribbons requires rewinding, which consumes a lot of manpower, resources, and time, affecting production capacity. In the existing operation method, in order to reduce the problem of wrinkles at the bottom of the roll, the operator needs to use double-sided tape to stick the copy paper to the take-up drum before starting the machine to rewind. In this process, the following problems exist: Since the copy paper is bonded to the double-sided tape by the ribbon attracting static electricity, both ends need to be stretched straight and pasted horizontally downwards when applying the double-sided tape to ensure that both ends are pasted on the ribbon at the same time. Otherwise, due to the static attraction, the ribbon will be attracted to the double-sided tape, causing wrinkles at the bottom of the roll. At this time, the equipment needs to be started, the end composite paper needs to be cut off and re-pasted, which affects efficiency and production capacity.

[0003] Therefore, this invention addresses the shortcomings of existing equipment by developing this device to solve the problem of roll bottom wrinkles during winding. Summary of the Invention

[0004] This invention provides an electrostatic adsorption paper processing device and a winding method, which can effectively solve the above-mentioned problems.

[0007] The winding device includes a winding drum support, which is connected to the winding drum. The winding drum is in contact with the winding roller. A heat sealing assembly is provided above the winding roller. An air blowing device is provided at one end of the winding drum support away from the winding roller.

[0011] As a further improvement, the first unwinding mechanism includes a first motor connected to a first unwinding chuck; the second unwinding mechanism includes a second motor connected to a second unwinding chuck; the first and second unwinding chucks are connected to a base material roll, and tension sensors are provided in the first and second unwinding chucks.

[0012] As a further improvement, a color difference sensor is provided above the first unwinding mechanism, and the first conveying roller through which the first unwinding mechanism and the second unwinding mechanism pass is a correction roller, with a correction device provided above the correction roller.

[0013] As a further improvement, the slitting device includes a third motor that drives a cutter shaft connected to a cutter spindle, and the cutter spindle is equipped with a plurality of cutters.

[0014] A method for winding electrostatic adsorption copy paper, applicable to an electrostatic adsorption copy paper processing device, characterized by comprising the following steps:

[0015] S1: The carbon ribbon is unwound from the first unwinding mechanism, the double-sided offset paper is unwound from the second unwinding mechanism, and the tape is threaded to the winding device. The unwinding tension and winding tension are set.

[0016] S2: Adjust the position of the guide according to the width of the base material so that the double-sided offset paper and carbon ribbon can move within the guide's correction range;

[0017] S3: The carbon ribbon is charged with static electricity by the electrostatic generator, and the double-sided offset paper and the carbon ribbon are automatically wound together by the self-winding roller. The wound copy paper is then automatically cut by the self-slitting device.

[0018] S4: The combined copy paper is moved to the take-up drum by the take-up roller, leaving a length of 3-5cm;

[0019] S5: Turn on the air blowing device to blow air, so that the combined copy paper moves around the take-up drum under the action of the air force to the heat sealing component for sealing.

[0023] The beneficial effects of this invention are:

[0024] (1) The present invention abandons the independent motor control of the traditional winding method and adopts the winding drum to be attached to the winding roller, and the pressure roller to press down and attach to the winding drum to ensure winding stability. The advantage of using this method is that the winding drum and the winding roller rotate synchronously, avoiding the problem of carbon belt wrinkling due to speed difference.

[0025] (2) When rewinding, the combined copy paper is moved to the take-up drum by the take-up roller, leaving a length of 3-5cm.

Under the action of the air flow, the carbon ribbon is more smoothly attached to the combined copy paper. The first cylinder group presses down to seal the bottom of the combined copy paper roll. The purpose of sealing is to prevent wrinkles from appearing when the bottom of the combined copy paper roll is rewound. Due to the action of the air blowing device, the combined copy paper is attached to the take-up drum. The pressure roller moves down to attach to the take-up drum and presses against the combined copy paper. At this time, the equipment is started. Under the rotation of the take-up roller, the take-up drum and the pressure roller rotate to rewind. The rewinding device does not require manual double-sided tape operation, avoiding wrinkles of the rewind carbon ribbon due to human operation and improving the working efficiency of the equipment.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] Example 1:

[0053] Reference Figure 3-7As shown, an electrostatic adsorption copier paper processing device includes an unwinding device 10 at the head of the machine and a rewinding device 20 at the tail. The unwinding device 10 includes a first unwinding mechanism 101 for unwinding the carbon ribbon and a second unwinding mechanism 102 for unwinding the offset paper. Several conveyor rollers are arranged between the unwinding device 10 and the rewinding device 20, and these conveyor rollers are connected by belts to ensure consistent speed differences. A winding roller 70 is arranged near one end of the rewinding device 20. The diameter of the winding roller 70 is larger than that of ordinary conveyor rollers because a larger diameter results in a greater force, effectively adsorbing the carbon ribbon onto the offset paper. An electrostatic generator 30 is arranged on one of the conveyor rollers near the rewinding device through which the carbon ribbon passes. The electrostatic generator 30 primarily generates static electricity, and its output is typically of single polarity, but can be positive or negative. The output voltage is adjustable. The electrostatic generator 30 is rectangular, with a width of [missing information]. The electrostatic generator 30 consists of an electrostatic emission rod and a DC high-voltage power supply. The DC high-voltage power supply provides negative or positive high voltage to the electrostatic emission rod, causing it to emit negative ions, which then charge the object. The electrostatic generator 30 is positioned above the conveyor roller of the machine. The optimal distance between the electrostatic generator 30 and the ribbon is 30-50mm. The electrostatic generator 30 causes the ribbon to attract static electricity, facilitating the bonding of the ribbon and the offset paper. A slitting device 40 is provided between the winding device 20 and the winding roller 70. This equipment is an integrated winding and slitting device. The ribbon and offset paper are unwound by the first unwinding mechanism 101 and the second unwinding mechanism 102, and then wound together at the winding roller 70. After winding, the paper is slitted to different sizes and specifications of copy paper according to different printer sizes. Compared with existing winding and slitting machines, this equipment has a reasonable structure, high efficiency, stable operation, and low defect rate.

[0054] The winding device 20 includes a winding drum support 201. The winding drum support 201 has hinge seats at both ends, which are connected to locking latches. The winding drum support 201 is connected to a winding drum 202. The winding drum 202 is fixedly connected using an optical shaft with bearings at both ends. The bearings of the optical shaft are mounted on the winding drum support 201 for rotation. This connection method is used in this embodiment and is not further limited here. The winding drum 202 is in contact with the winding roller 203. The winding roller 203 includes a first winding roller 203a and a second winding roller 203b. The first winding roller 203a is the driving roller, and the second winding roller 203b is the driven roller. Both the first winding roller 203a and the second winding roller 203b are in contact with the winding drum 202. The first winding roller 203a and the second winding roller 203b are not in contact during transmission. In the prior art, adding the second winding roller 203b can improve the stability of winding, thereby reducing the unevenness of the end face of the finished small roll. To address issues such as wrinkles in the composite copy paper, the take-up roller 203 is a rubber roller. It adheres to the take-up drum 202 to prevent damage to both the take-up drum 202 and the composite copy paper. A heat-sealing assembly 204 is positioned above the take-up roller 203 to seal the ends of the composite copy paper, preventing ribbon wrinkles. An air blowing device 205 is located at the end of the take-up drum support 201 furthest from the take-up roller 203. A [further details about the device are missing from the original text.] The pressure roller assembly 206 abuts against the take-up drum 202 to fix the winding. This invention abandons the independent motor control of the traditional winding method. Instead, the take-up drum 202 is attached to the take-up roller 203, and the pressure roller 206e presses down and attaches to the take-up drum 202 to ensure winding stability. The advantage of using this method is that the take-up drum 202 and the take-up roller 203 rotate synchronously, avoiding the problem of carbon belt wrinkling caused by speed difference.

[0055] As a further improvement, the air blowing device 205 includes a gas guiding block 205a. In this embodiment, the gas guiding block 205a is rectangular and has a through hole at its bottom. The gas guiding block 205a has several guiding holes 205b arranged horizontally along its axis. The number of through holes is the same as the number of guiding holes 205b, both being four. The number of guiding holes 205b is not limited. The guiding holes 205b are equidistantly arranged to ensure that the gas is evenly covered on the composite copy paper. The guiding holes 205b are provided with gas guiding tubes 205c. The number of gas guiding tubes 205c is the same as the number of through holes. The gas guiding tubes 205c abut against the through holes. The gas guiding tubes 205c converge on another gas guiding tube 205c through a connector. The gas guiding tubes 205c are connected to the air gun 205d.

[0056] The heat sealing assembly 204 includes a heat sealing pressure plate 204a disposed above the take-up roller 203, and a heat sealing cover plate 204b disposed above the heat sealing pressure plate 204a. A first cylinder group 204c drives the heat sealing cover plate 204b and presses down to seal the bottom of the combined copy paper roll. The purpose of sealing is to avoid wrinkles when the bottom of the combined copy paper roll is rewound. The working principle of the heat sealing assembly 204 is as follows: by using various external conditions such as electric heating, high frequency voltage and ultrasound, the sealing part of the plastic film is heated and becomes viscous. With the help of a certain pressure, the two layers of film are fused together. After cooling, a certain strength and sealing performance are maintained. Heat sealing is a sealing process in which heat and pressure are applied to one thermoplastic and then to another similar thermoplastic. The direct contact method of heat sealing uses a continuously heated mold or sealing strip to apply heat to a specific contact area or path to seal or weld the thermoplastics together. Heat sealing is used in many applications, including heat-sealing connectors, heat-activated adhesives, film media, plastic ports or foil seals, and can also be used for sealing the bottom of carbon ribbons and double-sided tape rolls.

[0057] As a further improvement, the pressure roller assembly 206 includes a second cylinder group 206a disposed on the tail suspension column. The second cylinder group 206a is connected to a crossbeam plate 206b. Both ends of the crossbeam plate 206b are connected to slider plates 206c. The slider plates 206c are rectangular plates, and a plurality of shaft holes are provided at the end of the slider plate 206c away from the crossbeam plate 206b. In this embodiment, four shaft holes are symmetrically arranged. The slider plate 206c is slidably connected to a limiting plate 206d. The limiting plate 206d is provided with an optical axis that is adapted to the slider plate 206c. The shaft hole is slidably connected to the optical axis, so that the slider plate 206c slides within the length limit of the optical axis. The limiting plate 206d is fixedly provided on the inner wall of the machine tool. A pressure roller 206e is provided below the crossbeam plate 206b. The pressure roller 206e is provided on the slider plate 206c. A bearing hole is provided at the bottom of the slider plate 206c. A bearing is provided in the bearing hole and the bearing is connected to the slider plate 206c.

[0058] The first unwinding mechanism 101 includes a first motor 101a, which drives a first unwinding chuck 101b; the second unwinding mechanism 102 includes a second motor 102a, which drives a second unwinding chuck 102b; the first unwinding chuck 101b and the second unwinding chuck 102b are connected to the base material roll 103; tension sensors are installed in the first unwinding chuck 101b and the second unwinding chuck 102b. The principle of the tension sensor is to achieve constant tension or tapered tension control of the base material, and its function is to achieve synchronization between guide rollers and uniform control of winding and unwinding; the tension controller combined with a magnetic powder brake or clutch can change the magnitude of the torque to maintain constant tension during winding and unwinding; if the tension sensor controls the tension, if the tension is insufficient, the base material will deform excessively; if the tension is too high, the raw material will easily break. A typical tension sensor mainly consists of a tension controller, a tension reader, a tension detector, a brake, and a clutch. Tension control systems can be classified into open-loop, closed-loop, or free-loop systems based on the loop structure; they can also be classified into ultrasonic, floating roller, and tracking arm types based on the monitoring method for different base materials. Since tension sensors are existing technology, no further restrictions are placed on the monitoring method for different base materials.

[0059] A color difference sensor 50 is installed above the first unwinding mechanism 101. The photoelectric sensor principle of the color difference meter is based on the photoelectric effect. The photoelectric effect includes the external photoelectric effect and the internal photoelectric effect. The external photoelectric effect is the emission of electrons from the surface of an object under the action of light, which is the classically summarized Einstein photoelectric effect equation. The color difference sensor 50 detects the blue tape at the bottom of the base material roll to trigger an alarm and automatically stop the machine, preventing tape slippage due to operator negligence. Tape slippage occurs when the base material is exhausted but the equipment continues to run, causing all the base material at the bottom of the roll to be transferred to the take-up end. At this time, the operator needs to re-roll and re-thread the tape, which consumes a lot of time. The first conveyor roller through which the first unwinding mechanism 101 and the second unwinding mechanism 102 pass is the correction roller 60, and a correction device 601 is installed above the correction roller 60. The working principle of the correction device 601 is as follows: During the material winding process, the photoelectric sensor detects the position of the edge or line to pick up the edge or line position deviation signal. The position deviation signal is then transmitted to the photoelectric correction controller for logical calculation, which sends a control signal to the mechanical actuator to drive the actuator, correcting the serpentine deviation during material movement and ensuring linear material movement. Optional left and right limit switches can be installed to prevent system malfunction. The correction device 601 is connected to the correction roller 60. When the material is about to deviate from its original track, the correction roller 60 moves left or right to adjust the base material position, achieving stability during equipment operation. The position of the correction device 601 is set according to the base material width, ensuring the carbon ribbon adheres to the center of the double-sided adhesive paper. Typically, the two correction devices 601 are vertically positioned. Under the adjustment of the correction roller 60, the two base materials can maintain a basically vertical running direction, aiming to achieve an overlapping effect and reduce the loss of slitting scraps.

[0060] As a further improvement, the slitting device 40 includes a third motor 401, which drives a cutter shaft 402. The cutter shaft 402 is connected to a cutter spindle 403, which is equipped with several cutters 404. The third motor 401 can control the slitting device 40 to switch between slitting and threading states. During operation, the cutters 404 are stationary, and slitting is achieved by the material moving on the transmission roller. In this embodiment, the slitting blade is a round blade and is stationary. In other embodiments, a stationary square blade or a motor-driven round blade can also be used, which rotates and slitting when the device starts. Further limitations are not specified here.

[0061] A method for winding electrostatic adsorption copy paper, applicable to an electrostatic adsorption copy paper processing device, characterized by comprising the following steps:

[0062] S1: The carbon ribbon is unwound from the first unwinding mechanism, the double-sided offset paper is unwound from the second unwinding mechanism, and the tape is threaded to the winding device. The unwinding tension and winding tension are set.

[0063] S2: Adjust the position of the guide according to the width of the base material so that the double-sided offset paper and carbon ribbon can move within the guide's correction range;

[0064] S3: The carbon ribbon is charged with static electricity by the electrostatic generator, and the double-sided offset paper and carbon ribbon are automatically wound together by the self-winding roller 70. The wound copy paper is then cut by the self-slitting device.

[0065] S4: The combined copy paper is moved to the take-up drum by the take-up roller, leaving a length of 3-5cm;

[0066] S5: Turn on the air blowing device to blow air, so that the combined copy paper moves around the take-up drum under the action of the air force to the heat sealing component for sealing.

[0067] S6: The pressure roller moves downwards to fit against the winding drum for winding;

[0068] S7: A blue tape is installed at the bottom of the carbon ribbon base material roll for several meters. The color difference sensor detects the blue tape, slows down and stops the machine to change the base material roll.

[0069] During winding, the combined copy paper is moved to the winding drum 202 via the winding roller, leaving a 3-5cm length. The air blowing device 205 is activated to blow air, causing the combined copy paper to move around the winding drum 202 and to the heat sealing assembly 204 under the action of airflow. Under the action of airflow, the carbon ribbon adheres more smoothly to the combined copy paper. The first cylinder group 204c presses down to seal the bottom of the combined copy paper roll. The purpose of sealing is to prevent wrinkles from appearing at the bottom of the combined copy paper roll during winding. Due to the action of the air blowing device 205, the rolled copy paper is adhered to the take-up drum 202. The pressure roller 206e moves downward to adhere to the take-up drum 202 and presses against the rolled copy paper. At this time, the equipment is started. Under the rotation of the take-up roller 203, the take-up drum 202 and the pressure roller 206e rotate accordingly to wind up the paper. The winding device 20 does not require manual application of double-sided tape, avoiding wrinkles in the winding ribbon due to human operation and improving the working efficiency of the equipment.

[0070] As a further improvement, a blue adhesive tape is installed at the bottom 200 meters of the carbon ribbon base material roll, and the downtime is set to 20 seconds. A color difference sensor 50 is installed above the first unwinding mechanism 101. When the color difference sensor 50 detects a change in color difference, the equipment alarms, slows down, and stops.

[0071] The working principle of this device is as follows:

[0072] like Figure 8As shown, the carbon ribbon is placed in the first unwinding mechanism 101 above, with the front side of the carbon ribbon base material facing outwards. The front side of the carbon ribbon is the side with black carbon powder attached. The carbon ribbon is unwound using a bottom-feed method. The offset paper is placed in the second unwinding mechanism 102 below. Since the front and back sides of the offset paper are indistinguishable, the feeding direction of the offset paper can be arbitrary. In this embodiment, the feeding direction of the offset paper is top-feed. The two base materials are adjusted by the correction device 601 to limit their operation within a certain range of error, keeping them running on the original track without deviating from the route. The two base materials are transported by conveyor rollers. An electrostatic generator 30 is installed on the upper carbon ribbon near the take-up end. After the carbon ribbon is charged with static electricity, it is wound up by the winding roller 70. During winding, the front side of the carbon ribbon is bonded to the offset paper, that is, the side of the carbon ribbon bonded to the offset paper is the front side, and the side of the carbon ribbon bonded to the offset paper is the transfer layer. The electrostatic generator 30 operates above the carbon ribbon, so that the entire carbon ribbon is charged with static electricity. Therefore, it will not cause problems such as poor electrostatic adhesion due to static electricity on only one side of the carbon ribbon. After winding, it is cut into small rolls of a preset width by the slitting device 40, and then wound up by the take-up roller 203. The wound copy paper is moved to the take-up drum 202 by the take-up roller, leaving a length of 3-5cm. The blowing device 205 is turned on to blow air, so that the wound copy paper is blown by the wind. The ribbon moves down past the take-up drum 202 to the heat-sealing assembly 204. Under the action of gas flow, the ribbon adheres more smoothly to the roll of copy paper. The first cylinder group 204c presses down to seal the bottom of the roll of copy paper. The heat-sealing assembly 204 heats the ribbon into a viscous state and, with a certain pressure, adheres the ribbon to the offset paper. Due to the action of the air blowing device 205, the roll of copy paper adheres to the take-up drum 202. The pressure roller 206e moves downward to adhere to the take-up drum 202, pressing against the roll of copy paper. At this time, the equipment is started. Under the rotation of the take-up roller 203, the first take-up roller 203a rotates counterclockwise. The first take-up roller 203a is the driving roller, and the take-up drum 202 rotates accordingly to perform take-up. The rotation direction of the take-up drum 202 is opposite to that of the first take-up roller 203a, that is, clockwise. The second take-up roller 203b, as the driven roller, rotates close to the take-up drum 202. The rotation direction of the second take-up roller 203b is the same as that of the first take-up roller 203a, that is, counterclockwise. The pressure roller 206e abuts against the take-up drum 202. Therefore, the rotation direction of the pressure roller 206e is the same as that of the first take-up roller 203a, that is, counterclockwise, thereby driving the composite copy paper to achieve the purpose of take-up. Figure 9As shown, the arrow points to the direction of the belt travel at the winding end. This belt travel method can achieve better transmission effect and more stable winding. The base material roll 103 is equipped with blue tape at the bottom 200m. A color difference sensor 50 is installed above the first unwinding mechanism 101. When the color difference sensor 50 detects a change in color difference, the equipment alarms, slows down and stops.

[0074] like Figure 10 As shown, this embodiment is basically the same as embodiment one, except that the gas guiding block 205a is not only axially and horizontally arranged on one side of the take-up drum 202, but also includes a gas guiding block 205a arranged below the take-up drum 202 to realize bottom-up air supply. The gas guiding block 205a below the take-up drum 202 controls the gas flow rate through a throttle valve. The air volume below is less than the air volume at the parallel, making the composite copy paper flatter and facilitating the sealing of the hot pressing assembly.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
