Description

Technical Field

[0001] This application relates to the technical field of printing production equipment, and in particular to a dual-compartment feeding device for printing. Background Technology

[0002] In the cigarette box printing process, the feeding stage, as the core process of material supply, directly affects production efficiency and printing quality. With the increasing demand for large-scale production in the tobacco industry and the widespread adoption of automated production lines, the problem of frequent downtime for material replacement in traditional single-compartment feeding equipment has become increasingly prominent. This not only leads to production interruptions and reduced equipment utilization but also easily causes fluctuations in printing quality. To address this pain point, dual-compartment feeding equipment for printing has emerged. Its design, featuring alternating feeding from two rollers, aims to achieve continuous material supply without shutdown, adapting to the core requirements of continuous production.

[0003] Although existing dual-compartment feeding equipment for printing has the basic structure of alternating material feeding by two rollers, it still has obvious shortcomings in practical applications. For example, when new and old materials stick together, misalignment and weak adhesion can easily occur, leading to material breakage or conveying jams during the feeding process. Alternatively, the tension control precision of the traction mechanism may be insufficient, causing fluctuations in the material conveying speed before and after roller replacement, which can affect the stability of subsequent printing processes.

[0004] Regarding the aforementioned technologies, the applicant believes that there are defects in the process of continuous material feeding without stopping the machine, making it difficult to accurately connect and firmly adhere the materials. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a dual-compartment feeding device for printing.

[0006] This application provides a dual-compartment feeding device for printing, which adopts the following technical solution: A dual-compartment feeding device for printing includes a frame. The frame houses a feeding mechanism, a traction mechanism, an adhesive bonding mechanism, and an adhesive coating mechanism. The feeding mechanism is located on one side of the frame and includes a first material roller and a second material roller. The first material roller is rotatably connected to the frame, and the second material roller is rotatably connected to the frame, with the first material roller positioned above the second material roller. The traction mechanism is rotatably mounted on the other side of the frame. The adhesive bonding mechanism is rotatably mounted on the frame and located between the first material roller and the traction mechanism. The adhesive coating mechanism is mounted on the frame and located between the first material roller and the second material roller.

[0007] By adopting the above technical solution, a feeding mechanism, a traction mechanism, an adhesion mechanism, and a gluing mechanism are set in the frame. The feeding mechanism includes a first material roller and a second material roller. This dual-compartment equipment uses the alternating cooperation of the first and second material rollers. When the material on the first material roller is used up, the second material roller can immediately take over. Then, with the help of the gluing and adhesion mechanism, the material is bonded end to end, achieving seamless material supply and firm adhesion. This avoids the time loss of downtime due to material changes, allowing the printing equipment to operate continuously and significantly improving equipment utilization. It is especially suitable for large-scale production scenarios of batch printing, and can efficiently handle large-volume orders. It reduces the labor costs caused by manual material changes and also reduces the cost of operational errors that may occur during manual material changes. In addition, in continuous production mode, the material conveying is stable, which can reduce material loss caused by unstable material tension during restart, reduce scrap rate, and further save on the raw material cost of printing.

[0008] Preferably, the traction mechanism includes a main traction roller, a secondary traction roller, and a first motor; the main traction roller is rotatably mounted on the frame, the secondary traction roller is rotatably mounted on the frame, and the secondary traction roller is located above the main traction roller; the base of the first motor is mounted on the frame, the working end of the first motor is mounted on the main traction roller, and the first motor provides power for the rotation of the main traction roller.

[0009] By adopting the above technical solution, the first motor directly provides power to the main traction roller. The power transmission path is short and the loss is small. It can output a continuous and uniform traction force. The stable power output can ensure that the material is fed at a uniform speed before and after the roller is changed, avoiding material jamming, stretching or interruption of conveying due to power fluctuations. This provides a continuous material supply basis for subsequent printing processes. The auxiliary traction roller is located above the main traction roller, forming a roller group structure with upper and lower pressure, which can firmly clamp the paper, film and other materials used for printing between the two rollers.

[0010] Preferably, a first auxiliary roller is rotatably mounted on the frame on one side of the traction mechanism.

[0011] By adopting the above technical solution, the first auxiliary roller is rotated and set on one side of the traction mechanism, which can guide the new material output by the first material roller in a directional manner. In conjunction with the new material output by the second material roller of the adhesive mechanism, it can be precisely adhered at a preset angle, avoiding problems such as misalignment and uneven overlap caused by the deviation of the material conveying direction, greatly improving the adhesion success rate, and laying a solid foundation for continuous material supply in the dual-compartment system without stopping the machine.

[0012] Preferably, a stop roller is rotatably mounted on the top of the frame, and the stop roller is located above the glue application mechanism.

[0013] By adopting the above technical solution, the abutment roller is located above the glue coating mechanism and works with the glue coating mechanism to press against the material, so that the material and the glue coating mechanism maintain a stable and uniform contact pressure, avoiding uneven coating of the glued area due to the material being loose or wrinkled, and ensuring that the glue forms a flat and uniform glue layer on the surface of the printed material, laying the foundation for the firm adhesion of new and old materials.

[0014] Preferably, the glue application mechanism includes two sets of first push rods and a glue application roller. The two sets of first push rods are disposed on both sides of the glue application roller. The glue application roller is rotatably disposed at the working end of the first push rod. The base of the first push rod is disposed on the frame.

[0015] By adopting the above technical solution, the first push rod pushes the coating roller, ensuring that the effective working surface of the coating roller matches the material. Two sets of first push rods are symmetrically arranged on both sides of the coating roller, which can synchronously adjust the contact pressure between the coating roller and the material. Through the extension and retraction adjustment of the push rods, the coating pressure can be precisely controlled according to the thickness of the printed material, the material characteristics, and the type of adhesive. This avoids excessive pressure causing excessive glue extrusion or insufficient pressure causing insufficient coating or missed coating, ensuring that the adhesive layer thickness is uniform and consistent, and providing a guarantee for the firm adhesion of new and old materials.

[0016] Preferably, the adhesion mechanism includes two sets of second push rods and an adhesion roller; the two sets of second push rods are disposed on both sides of the adhesion roller, the adhesion roller is rotatably disposed at the working end of the second push rod, and the base of the second push rod is disposed on the top of the frame.

[0017] By adopting the above technical solution, two sets of second push rods symmetrically support both ends of the adhesive roller, and can synchronously extend and retract to adjust the contact pressure between the adhesive roller and the material, ensuring that the tail of the old material is bonded to the head of the new material. It can also precisely control the pressing force according to the different thicknesses, materials and adhesive characteristics of the printed materials, ensuring the continuity of material supply without stopping the machine in both chambers.

[0018] Preferably, an auxiliary mechanism is provided on the frame on one side of the second material roller. The auxiliary mechanism includes a second auxiliary roller and a second motor. The second auxiliary roller is rotatably mounted on the frame and is located between the second material roller and the adhesion mechanism. The base of the second motor is mounted on the frame, and the working end of the second motor is mounted on the second auxiliary roller. The second motor provides power for the rotation of the second auxiliary roller.

[0019] By adopting the above technical solution, the second motor provides power to the second auxiliary roller, forming an active traction mode, which provides directional and uniform conveying power for the new material on the second material roller. It can quickly drive the new material to the adhesion mechanism, ensuring that the new and old materials are connected in a timely manner at the preset position, avoiding problems such as connection delay and missed adhesion due to insufficient conveying power of the new material. The second auxiliary roller is located between the second material roller and the adhesion mechanism, forming a dedicated guide channel to accurately correct the conveying direction.

[0020] Preferably, both the first and second material rollers are provided with a cutting mechanism, which includes a cutting blade, a drive spring, a drive slider, and a mounting frame. One end of the mounting frame has a drive cavity, and the other end has a sliding cavity. The drive slider is slidably disposed at one end of the drive cavity, located below the first or second material roller. The cutting blade is slidably disposed in the sliding cavity, which is connected to the other end of the drive cavity. The cutting blade is located on one side of the first or second material roller. The drive spring is sleeved on the drive slider, with one end fixedly disposed on the mounting frame and the other end fixedly disposed on the drive slider.

[0021] By adopting the above technical solution, the cutting mechanism relies on the thickness of the material itself to trigger the cutting. When the first or second material roller is full, the material thickness presses against the drive slider and compresses the drive spring, and the cutting blade remains in the standby position. As the material is consumed and becomes thinner, the spring force is gradually released, pushing the drive slider to pop out, and then driving the cutting blade to slide and complete the cutting. It can accurately capture the critical point of material remaining and automatically complete the cutting when the old material is about to be used up. This avoids material waste caused by premature cutting and also prevents the lag in cutting from affecting the adhesion of new material, ensuring seamless connection of the dual-bin material supply process and improving the automation level of the production line.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The machine frame is equipped with a feeding mechanism, a traction mechanism, an adhesion mechanism, and a gluing mechanism. The feeding mechanism includes a first material roller and a second material roller. This dual-compartment equipment uses the alternating cooperation of the first and second material rollers. When the material on the first material roller is used up, the second material roller can immediately take over. Then, with the help of the gluing and adhesion mechanism, the material is adhered end to end, achieving seamless material supply. This avoids the time loss of downtime when changing materials, allowing the printing equipment to operate continuously and significantly improving the equipment utilization rate. It is especially suitable for large-scale production scenarios of batch printing and can efficiently handle large-volume orders.

[0023] 2. The cutting mechanism relies on the thickness of the material itself to trigger the cutting. When the first or second material roller is full, the material thickness presses against the drive slider and compresses the drive spring, keeping the cutting blade in the standby position. As the material is consumed and becomes thinner, the spring force is gradually released, pushing the drive slider out and then driving the cutting blade to slide and complete the cutting. It can accurately capture the critical point of material remaining and automatically complete the cutting when the old material is about to be used up. This avoids material waste caused by premature cutting and also prevents the new material from sticking due to the delay in cutting. It ensures seamless connection of the dual-bin material supply process and improves the automation level of the production line. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0028] This application discloses a dual-compartment feeding device for printing. (Refer to...) Figure 1The system includes a frame 1, within which are installed a feeding mechanism 2, a traction mechanism 3, an adhesive mechanism 4, and an adhesive application mechanism 5. The feeding mechanism 2 is located on one side of the frame 1 and includes a first material roller 21 and a second material roller 22. The first material roller 21 is rotatably connected to the frame 1, and the second material roller 22 is rotatably connected to the frame 1, with the first material roller 21 positioned above the second material roller 22. The traction mechanism 3 is rotatably located on the other side of the frame 1. The adhesive mechanism 4 is rotatably mounted on the frame 1 and is located between the first material roller 21 and the traction mechanism 3. The adhesive application mechanism 5 is located on the frame 1. On frame 1, the glue application mechanism 5 is located between the first material roller 21 and the second material roller 22; the traction mechanism 3 includes a main traction roller 31, an auxiliary traction roller 32 and a first motor 33; the main traction roller 31 is rotatably mounted on frame 1, the auxiliary traction roller 32 is rotatably mounted on frame 1, and the auxiliary traction roller 32 is located above the main traction roller 31; the base of the first motor 33 is mounted on frame 1, the working end of the first motor 33 is mounted on the main traction roller 31, the first motor 33 provides power for the rotation of the main traction roller 31, and the material of the second material roller 22 is traction-loaded by the main traction roller 31.

[0029] Reference Figure 1 and Figure 2 Both the first material roller 21 and the second material roller 22 are equipped with a cutting mechanism 6. The cutting mechanism 6 includes a cutting blade 61, a drive spring 62, a drive slider 63, and a mounting frame 64. One end of the mounting frame 64 is provided with a drive cavity 641, and the other end of the mounting frame 64 is provided with a sliding cavity 642. The drive slider 63 is slidably disposed at one end of the drive cavity 641 and is located below the first material roller 21 or the second material roller 22. The cutting blade 61 is slidably disposed in the sliding cavity 642, and the sliding cavity 642 is connected to the other end of the drive cavity 641. The cutting blade 61 is located below the first material roller 21 or the second material roller 22. One side of roller 21 or the second material roller 22; the drive spring 62 is sleeved on the drive slider 63, one end of the drive spring 62 is fixedly mounted on the mounting bracket 64, and the other end of the drive spring 62 is fixedly mounted on the drive slider 63. When the traction mechanism 3 continuously pulls and feeds the material on the second material roller 22, the material on the second material roller 22 becomes thinner and thinner. Then the drive slider 63 is continuously slid outward from the drive cavity 641 by the force of the drive spring 62, and the drive cutting blade 61 moves along the sliding cavity 642 towards the material until the material on the second material roller 22 reaches the end, and the cutting blade 61 cuts the material.

[0030] Reference Figure 1An auxiliary mechanism 7 is provided on the frame 1 on one side of the second material roller 22. The auxiliary mechanism 7 includes a second auxiliary roller 71 and a second motor 72. The second auxiliary roller 71 is rotatably mounted on the frame 1 and is located between the second material roller 22 and the adhesion mechanism 4. The base of the second motor 72 is mounted on the frame 1, and the working end of the second motor 72 is mounted on the second auxiliary roller 71. The second motor 72 provides power for the rotation of the second auxiliary roller 71, forming active traction and providing orientation for the material on the second material roller 22. A stop roller 9 is rotatably mounted on the top of the frame 1. The stop roller 9 is located at... Above the glue coating mechanism 5, the glue coating mechanism 5 includes two sets of first push rods 51 and a glue coating roller 52. The two sets of first push rods 51 are arranged on both sides of the glue coating roller 52. The glue coating roller 52 is rotatably arranged at the working end of the first push rod 51. The base of the first push rod 51 is arranged on the frame 1. Glue is applied to the glue coating roller 52. When the material on the second material roller 22 is cut off, the second auxiliary roller 71 feeds the material into the glue coating mechanism 5. The first push rod 51 pushes the glue coating roller 52 to slide upward, so that the glue coating roller 52 abuts against the material. The glue coating roller 52 slides upward again, so that the glue coating roller 52 abuts against the stop roller 9 through the material. The glue coating roller 52 and the stop roller 9 evenly coat the bottom surface of the material with glue.

[0031] Reference Figure 1 A first auxiliary roller 8 is rotatably mounted on the frame 1 on one side of the traction mechanism 3. The first auxiliary roller 8 pulls the material of the first material roller 21. The adhesion mechanism 4 includes two sets of second push rods 41 and an adhesion roller 42. The two sets of second push rods 41 are located on both sides of the adhesion roller 42. The adhesion roller 42 is rotatably mounted on the working end of the second push rod 41. The base of the second push rod 41 is located on the top of the frame 1. When the traction mechanism 3 pulls the material with glue, the second push rod 41 will push the adhesion roller 42 downward, which, together with the first auxiliary roller 8, makes the material of the second material roller 22 firmly adhere to the material of the first material roller 21. At this time, the traction mechanism 3 continues to transport the material continuously.

[0032] The working principle of a dual-compartment feeding device for printing in this application is as follows: After the device is started, two sets of materials are provided by the first material roller 21 and the second material roller 22 of the feeding mechanism 2, respectively. The main traction roller 31 driven by the first motor 33 in the traction mechanism 3 provides the core traction force. At the same time, the auxiliary mechanism 7 on the frame 1 plays a role, and the second motor 72 drives the second auxiliary roller 71 to rotate actively, forming an active traction effect. This provides precise orientation for the material conveying of the second material roller 22, avoids material deviation, and ensures its smooth conveying to the subsequent mechanism. The first material roller 21 and Each of the second material rollers 22 is equipped with a cutting mechanism 6. The drive slider 63 of the cutting mechanism 6 is always in contact with the material on the roller due to the elastic force of the drive spring 62. As the traction mechanism 3 continues to pull, the material on the roller is gradually consumed and the thickness decreases. The elastic potential energy of the drive spring 62 is released, pushing the drive slider 63 to slide out of the drive cavity 641. The sliding of the drive slider 63 drives the cutting blade 61 to move along the sliding cavity 642 towards the material until the material on the roller is completely consumed. The cutting blade 61 then precisely cuts the material, completing the single roll of material. After the material on the second material roller 22 is cut by the cutting mechanism 6, the two sets of first push rods 51 of the gluing mechanism 5 are activated, pushing the gluing roller 52 to slide upward, so that the gluing roller 52 is in contact with the bottom surface of the material on the second material roller 22. The first push rods 51 continue to push the gluing roller 52 upward until the gluing roller 52 abuts against the stop roller 9 at the top of the frame 1 through the material. The gluing roller 52 and the stop roller 9 cooperate to form a clamping state. The material passes between the two at a uniform speed under the traction of the traction mechanism 3. During the rotation of the gluing roller 52, the glue on the surface is evenly applied. On the bottom surface of the material, the glued material is continuously tractioned by the traction mechanism 3 and conveyed to the bonding mechanism 4. The two sets of second push rods 41 of the bonding mechanism 4 are activated and push the bonding roller 42 downward. The bonding roller 42 cooperates with the first auxiliary roller 8 to clamp the material of the first material roller 21 and the glued material of the second material roller 22 from the upper and lower sides. The pressure makes the two types of materials firmly bonded, ensuring tight bonding without air bubbles or deviation. After the two types of materials are bonded, the traction mechanism 3 continues to provide uninterrupted traction force to convey the bonded composite material outward, realizing continuous processing.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. 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.
