Description

Technical Field

[0001] This application relates to the technical field of packaging material processing equipment, and in particular to a printing material cutting and separating device. Background Technology

[0002] In the production process of paper tape used in printing, the cutting and separating device is the core equipment connecting the raw paper processing and subsequent forming processes. Its main function is to cut the roll of wide paper tape into narrow strips of specified width according to process requirements, and to complete the separation and rewinding of the paper tape, providing raw materials that meet specifications for subsequent printing, lamination or assembly processes. Its operating efficiency and processing quality have a decisive impact on the capacity and product qualification rate of the entire production line.

[0003] Currently available paper tape cutting and separating devices transport wide paper tapes to a cutting roller via a traction mechanism. After being cut by the blades on the cutting roller, multiple narrow paper tapes are initially combed through a single separating roller and then transported along the same path to a single winding roller for centralized winding. These devices have a relatively simple structure and low manufacturing cost, but they have revealed significant shortcomings in actual production. For example, the paper tapes are prone to tangling due to electrostatic adsorption or uneven tension during winding, and the deviation during winding is difficult to control effectively.

[0004] Regarding the aforementioned technologies, the applicant believes that there is a defect where the paper tape will deviate during winding after cutting. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a printing material cutting and separating device.

[0006] This application provides a printed matter cutting and separating device, which adopts the following technical solution: A printing material cutting and separating device includes a cutting assembly, a separating assembly, a rewinding assembly, and a frame. The cutting assembly is disposed at one end of the frame and includes an auxiliary roller, a cutting roller, a cutting motor, and a traction mechanism. The auxiliary roller is rotatably disposed at one end of the frame. The traction mechanism is disposed on the frame and located on one side of the auxiliary roller. The cutting roller is rotatably disposed on the frame and located between the auxiliary roller and the traction mechanism, and multiple sets of cutting blades are disposed on the cutting roller. The separating assembly is disposed at the other end of the frame, and the rewinding assembly is disposed on the frame and located above the separating assembly. The working end of the cutting motor is disposed on the cutting roller, and the cutting motor provides power for the rotation of the cutting roller.

[0007] By adopting the above technical solution, the cutting roller is equipped with multiple sets of cutting blades, which, together with the auxiliary rollers and traction mechanism, ensure uniform force and smooth conveying during paper tape cutting. This avoids problems such as rough edges, burrs, or paper tearing during the cutting process, improves the straightness of the cut, and ensures the dimensional consistency of individual paper tapes. The separation component separates the cut paper tapes in an interleaved manner, preventing the problems of multiple paper tapes adsorbing, sticking, or stacking unevenly after cutting from the source, and eliminating conveying interference caused by factors such as static electricity. The winding component works with the separation component to achieve the correction function, effectively preventing deviation and edge running during paper tape conveying and winding, ensuring tight, neat, and wrinkle-free winding. The integrated design of cutting, separating, and winding eliminates the need for additional manual intervention in the paper tape sorting after slitting, reduces the time spent on process connections, and improves overall production efficiency. Multiple sets of cutting blades can be flexibly adjusted according to the paper tape width requirements to adapt to the processing needs of different specifications of products. The components are reasonably arranged through the frame, ensuring stable power transmission, reducing vibration and failure during equipment operation, extending the service life of the equipment, and reducing the frequency of maintenance.

[0008] Preferably, the winding assembly includes a first winding roller, a second winding roller, and a drive mechanism; the first winding roller is rotatably mounted on the frame and is located on one side of the separation assembly; the second winding roller is rotatably mounted on the frame and is located on the other side of the separation assembly; both the first and second winding rollers are provided with multiple winding wheels; the drive mechanism provides power for the rotation of the first and second winding rollers.

[0009] By adopting the above technical solution, the first and second winding rollers are respectively located on both sides of the separation component. With the staggered separation function of the separation component, the double-sided diversion and winding of multiple paper strips after cutting can be achieved. Compared with the centralized winding of a single winding roller, it can completely avoid the paper strips from squeezing, tangling or overlapping at the edges during the winding process. The spatial layout enhances the correction effect. The multiple winding wheels correspond to the cutting blade, so that each paper strip is independently wound on the corresponding winding wheel, ensuring that the winding tension of each paper strip is uniform and the roll diameter is consistent. This further improves the winding flatness and dimensional accuracy, meeting the high standard requirements of subsequent paper strip processing. The first winding roller, the second winding roller and the multiple winding wheels can all be independently disassembled and the spacing can be adjusted. The number and arrangement of winding wheels can be flexibly configured according to the specifications such as the width and number of paper strips.

[0010] Preferably, the winding reel is provided with an adhesive coating structure, which includes a sliding cavity, an adhesive-coated slide plate, a sliding rod, a top spring, and a handle. The sliding cavity is disposed within the winding reel, with an adhesive coating opening at its top and a sliding opening on its side. One end of the sliding opening has a limit groove. One end of the top spring is fixedly disposed at one end of the sliding cavity, and the other end of the top spring is fixedly disposed at one end of the sliding rod. One end of the handle is rotatably disposed at one end of the sliding rod, and the other end of the handle is disposed outside the winding reel through the sliding opening. One end of the adhesive-coated slide plate is fixedly disposed at the other end of the sliding rod.

[0011] By adopting the above technical solution, the top spring continuously provides elastic pushing force, ensuring that the adhesive-coated slide plate always adheres to the glued opening. When the paper tape is wound into a roll, it can contact the adhesive-coated slide plate in real time and complete the adhesion and fixation, avoiding loosening, slippage, or displacement of the paper tape in the early stage of winding, ensuring the tightness and stability of the winding. The adhesive-coated slide plate is rigidly connected to the top spring through the sliding rod, and the adhesion pressure is uniform and continuous, which can avoid the problem of weak adhesion caused by uneven glue application, ensuring the consistency of the fixing effect of the entire roll of paper tape from the beginning to the end, and improving the quality of the roll. The extension and retraction of the adhesive-coated slide plate can be controlled by the extended handle. When unwinding, pulling the handle compresses the top spring through the sliding rod, and the adhesive-coated slide plate retracts into the sliding cavity simultaneously, completely separating the paper tape from the glued structure. There is no need to pry or cut the paper tape, realizing the quick disassembly of the rolled paper tape. The handle is rotatably connected to the sliding rod, and the end of the sliding opening is provided with a limiting groove. After pulling the handle, it can be locked into the limiting groove for positioning, keeping the adhesive-coated slide plate in the retracted state without continuous gripping.

[0012] Preferably, the separation assembly includes a separation roller, a first guide mechanism, a second guide mechanism, and a power motor; the separation roller is rotatably mounted on the frame; the first guide mechanism is mounted on the frame, with one end positioned below the multi-component reel of the first take-up roller and the other end positioned below the separation roller; the second guide mechanism is mounted on the frame, with one end positioned below the multi-component reel of the second take-up roller and the other end positioned above the separation roller; the working end of the power motor is fixedly mounted on one end of the separation roller, and the power motor provides power for the rotation of the separation roller.

[0013] By adopting the above technical solution, the separating roller, together with the first and second guiding mechanisms distributed vertically, forms a conveying path with intermediate separation and double-sided diversion. After the multiple paper strips are combed by the separating roller, they are conveyed separately by the first and second guiding mechanisms to achieve odd and even strips, completely isolating the paper strips on both sides in space. This avoids the problems of paper strips adsorbing, tangling, or overlapping at the edges in traditional single-path conveying. The guiding path is precisely aligned with the winding direction, keeping the conveying trajectory of the paper strip from the separation end to the winding end straight, effectively offsetting the offset tendency caused by uneven tension of the paper strip itself or equipment vibration. The separating roller is driven by an independent power motor, and its speed can be precisely matched with the conveying speed of the cutting component, ensuring stable force and synchronous conveying during paper strip separation. This avoids paper strip pulling and wrinkling caused by mismatch between separation speed and cutting speed, improving separation accuracy and paper strip integrity.

[0014] Preferably, the first guiding mechanism includes a first guiding plate, a first clamping plate, a first guiding roller, and multiple sets of retaining top members; the multiple sets of retaining top members are disposed on a frame below the first take-up roller; each retaining top member includes a first sleeve, a first sliding rod, and a first spring; the first guiding plate is fixedly disposed on the frame, with one end of the first guiding plate disposed below the separating roller; the first guiding roller is rotatably disposed at the other end of the first guiding plate; the first sleeve is fixedly disposed on the frame; the bottom of the first sliding rod is slidably disposed within the first sleeve, and the top of the first sliding rod abuts against one end of the first clamping plate; the first spring is disposed within the first sleeve, with one end of the first spring fixedly disposed at the bottom of the first sleeve, and the other end of the first spring fixedly disposed at the bottom of the first sliding rod; the other end of the first clamping plate is rotatably disposed at the other end of the first guiding plate; one end of the first guiding plate is configured as a branch corresponding to the winding wheel of the first take-up roller.

[0015] By adopting the above technical solution, multiple sets of retaining top members provide continuous elastic pushing force to the first slide rod through the first spring, ensuring that the first clamping plate is always tightly attached to the paper tape roll on the winding wheel. The flipping angle and bonding pressure of the first clamping plate can be automatically adjusted according to the real-time changes in the paper tape roll diameter, ensuring that the paper tape is always subjected to uniform guiding tension throughout the winding process, avoiding paper tape loosening, deviation, or wrinkling due to increased roll diameter. The elastic force of the first spring can adaptively buffer the pressure fluctuations caused by changes in paper tape roll diameter, avoiding excessive pressure leading to paper tape damage or insufficient pressure leading to guiding failure, adapting to the winding requirements of paper tapes of different thicknesses and materials, improving the stability of the guiding process and the integrity of the paper tape. In conjunction with the steering guidance of the first guide roller, the paper tape output from the separation roller is accurately transported along a preset path to the corresponding winding wheel of the first winding roller, effectively counteracting the lateral deviation trend during the paper tape transportation process.

[0016] Preferably, the second guiding mechanism includes a second guiding plate, a second clamping plate, a second guiding roller, and multiple sets of retaining pull members; the multiple sets of retaining pull members are disposed on the frame on one side of the second take-up roller; each retaining pull member includes a second sleeve, a second slide rod, and a second spring; the second guiding plate is fixedly disposed on the frame, with one end of the second guiding plate disposed above the separating roller; the second guiding roller is rotatably disposed on the other end of the second guiding plate; the second sleeve is fixedly disposed on the frame; the bottom of the second slide rod is slidably disposed within the second sleeve, and multiple sets of sliders are slidably disposed at the bottom of one end of the second clamping plate, with the top of the second slide rod rotatably disposed on the sliders; the second spring is disposed within the second sleeve, with one end of the second spring fixedly disposed at the bottom of the second sleeve, and the other end of the second spring fixedly disposed at the bottom of the second slide rod; the other end of the second clamping plate is rotatably disposed at the other end of the second guiding plate; one end of the second guiding plate is configured as a branch corresponding to the winding wheel of the second take-up roller.

[0017] By adopting the above technical solution, multiple sets of retaining pull members provide continuous elastic tension to the second slide rod through the second spring. Combined with the rotational connection between the second clamping plate and the second guide plate, the second clamping plate is always in close contact with the surface of the winding wheel of the second take-up roller with appropriate pressure. According to the real-time changes of the paper tape from the initial to full roll, the flip angle of the second clamping plate is automatically adjusted by the extension and contraction of the second spring. At the same time, the rotational cooperation between the slider and the second slide rod ensures that the clamping pressure is evenly distributed, avoiding the paper tape from loosening, shifting, or wrinkling due to the increase in roll diameter, and ensuring stable tension throughout the winding process. The elastic effect of the second spring The force can buffer the impact caused by changes in the paper tape diameter, avoiding excessive pressure that could damage the paper tape or insufficient pressure that could lead to guide failure. It adapts to the winding requirements of paper tapes of different thicknesses and materials, improving the adaptability of the guiding process and the integrity of the paper tape. In conjunction with the rolling guidance of the second guide roller, the paper tape output from above the separation roller is accurately transported along a preset path to the corresponding winding wheel of the second winding roller, effectively counteracting the lateral offset trend during the paper tape transportation process. It works in synergy with the double-sided symmetrical layout of the first guide mechanism to further consolidate the staggered separation effect of the separation component and ensure the synchronicity and accuracy of the double-sided winding.

[0018] Preferably, the traction mechanism includes a main traction roller, a secondary traction roller, and a mounting frame; the main traction roller is rotatably disposed at the bottom of the mounting frame; the secondary traction roller is slidably disposed on the mounting frame, and the secondary traction roller is located above the main traction roller; the mounting frame is fixedly disposed on the machine frame.

[0019] By adopting the above technical solution, the main traction roller and the auxiliary traction roller are set up vertically to form a clamping traction structure. The sliding adjustment of the auxiliary traction roller can achieve tight clamping of paper tapes of different thicknesses, ensuring that the paper tape does not slip or deviate during the traction process, and providing a stable conveying foundation for the precise cutting of the subsequent cutting components.

[0020] Preferably, the driving mechanism includes a first motor and a second motor; the working end of the first motor is fixedly disposed at one end of the first take-up roller, the first motor is used to drive the first take-up roller to rotate, and the base of the first motor is fixedly disposed on the frame; the working end of the second motor is fixedly disposed at one end of the second take-up roller, the second motor is used to drive the second take-up roller to rotate, and the base of the second motor is fixedly disposed on the frame.

[0021] By adopting the above technical solution, the first motor and the second motor independently drive the first winding roller and the second winding roller, respectively. The speed of each motor can be precisely adjusted according to the winding state of the paper tape on both sides, so as to realize the independent control of the winding speed on both sides. Compared with the single motor linkage drive, it avoids the problems of asynchronous winding on both sides, paper tape stretching and slack caused by the tension fluctuation of the paper tape on one side or the difference in roll diameter. It ensures that the winding tension of the paper tape on both sides is uniform and the roll diameter is consistent, thus improving the stability of winding quality.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The top spring continuously provides elastic pushing force, ensuring the adhesive-coated slide plate always adheres to the glued opening. As the paper tape winds into a roll, it contacts the adhesive-coated slide plate in real time for secure bonding, preventing loosening, slippage, or displacement of the paper tape during the initial winding stage. This ensures the tightness and stability of the rolled-up structure. The adhesive-coated slide plate is rigidly connected to the top spring via a sliding rod, providing uniform and continuous bonding pressure. This avoids problems caused by uneven glue application, ensuring consistent bonding from the beginning to the end of the roll and improving roll quality. The extension and retraction of the adhesive-coated slide plate can be controlled via an extended handle. When unwinding, pulling the handle compresses the top spring via the sliding rod, causing the adhesive-coated slide plate to retract into the sliding cavity simultaneously. The paper tape completely separates from the glued structure, eliminating the need to pry or cut the paper tape and enabling rapid unwinding of the rolled paper tape. The handle is rotatably connected to the sliding rod, and a limiting groove is provided at the end of the sliding opening. Pulling the handle allows it to be engaged in the limiting groove for positioning, maintaining the retracted state of the adhesive-coated slide plate without continuous gripping.

[0023] 2. The separating roller, in conjunction with the first and second guiding mechanisms distributed vertically, forms a conveying path with intermediate separation and double-sided diversion. After the multiple paper strips are combed by the separating roller, they are conveyed separately by the first and second guiding mechanisms to separate odd and even strips, completely isolating the paper strips on both sides in space. This avoids the problems of paper strips adhering to each other, tangling, or overlapping edges in traditional single-path conveying. The guiding path is precisely aligned with the winding direction, ensuring that the conveying trajectory of the paper strip from the separation end to the winding end remains straight, effectively offsetting the offset tendency caused by uneven tension of the paper strip itself or equipment vibration. The separating roller is driven by an independent power motor, and its speed can be precisely matched with the conveying speed of the cutting components, ensuring stable force and synchronous conveying during paper strip separation. This avoids paper strip pulling and wrinkling caused by mismatch between separation speed and cutting speed, improving separation accuracy and paper strip integrity. Attached Figure Description

[0037] The working principle of the printing cutting and separating device in this application is as follows: The whole sheet of paper to be processed is first conveyed to the cutting assembly 1 at one end of the frame 4. The auxiliary roller 11 guides and supports the paper by rotating, ensuring the stability of the paper's conveying posture. When the paper continues to be conveyed to the traction mechanism 14, the secondary traction roller 142 forms a clamping cooperation with the main traction roller 141 by its own weight. Under the synchronous rotation of the main traction roller 141 and the secondary traction roller 142, a continuous and uniform traction force is provided to the paper, ensuring that the paper is conveyed to the cutting roller 12 at a constant speed, avoiding slippage or conveying deviation. After the cutting motor 13 starts, it drives the cutting roller 12 to rotate. The multiple sets of cutting blades 121 on the cutting roller 12 rotate synchronously with the cutting roller 12. When the paper is separated from the cutting roller 12 by the auxiliary roller 141, the paper is separated from the cutting roller 14 by the auxiliary roller 142. When the gap between the auxiliary roller 11 and the traction mechanism 14 passes through, multiple sets of cutting blades 121 divide the entire sheet of paper into multiple paper strips of the same specification along the width direction, preparing for subsequent slitting and winding. The cut paper strips are directly conveyed to the separation component 2. The power motor 24 drives the separation roller 21 to rotate, providing auxiliary power for the paper strip conveying. At the same time, the first guide mechanism 22 and the second guide mechanism 23 work together. The first guide plate 221 and the first guide roller 223 of the first guide mechanism 22 provide a downward guide path for the paper strip. Multiple sets of holding top members 224 push the first slide bar 2242 through the pushing force of the first spring 2243, so that the first clamping plate 222 always fits against the paper strip roll on the side of the first winding roller 31, ensuring the stability of the paper strip conveying; the second guide mechanism The second guide plate 231 and the second guide roller 233 provide an upper guide path for the paper tape. Multiple sets of retaining pullers 234 pull the second slide bar 2342 through the elastic tension of the second spring 2343. Combined with the sliding engagement of the second clamping plate 232 and the slider 2321, and the rotational connection between the second clamping plate 232 and the second guide plate 231, the second clamping plate 232 is always in contact with the paper tape roll on the side of the second take-up roller 32, adapting to the diameter change of the paper tape roll from the initial state to the full roll. Under the guidance of the rotation of the separating roller 21 and the first guide mechanism 22 and the second guide mechanism 23, multiple paper tapes are orderly separated and divided into two groups, which are respectively conveyed to the first take-up roller 31 and the second take-up roller 32 on both sides. The branching of the first guide plate 221 and the first take-up roller 32 are connected. The winding wheel 34 of the roller 31 is positioned corresponding to the winding wheel 34 of the second take-up roller 32 through the branching of the second guide plate 231, forming a double-sided diversion conveying path to achieve staggered conveying on both sides. When the paper roll is initially wound, the adhesive sliding plate 352 of the adhesive coating structure 35 inside the winding wheel 34 extends out from the adhesive opening 3511 under the elastic pushing force of the top force spring 354. After one end of the paper roll contacts the adhesive sliding plate 352, it is glued and fixed to the winding wheel 34. When the paper roll is wound to the preset length, the handle 355 is pulled. The handle 355 drives the sliding rod 353 to compress the top force spring 354, so that the adhesive sliding plate 352 retracts into the sliding cavity 351. The paper roll is separated from the adhesive coating structure 35, and the full roll of paper can be directly disassembled. The operation is convenient and efficient.After releasing handle 355, the top spring 354 returns to its original position, pushing the adhesive-coated slide plate 352 to extend again to the adhesive application opening 3511, allowing for the next round of winding.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
