Description

A super mini paper handkerchief folding and processing equipment Technical Field

[0001] This utility model relates to the field of paper handkerchief production equipment and technology, and in particular to an ultra-mini paper handkerchief folding and processing equipment. Background Technology

[0002] Paper handkerchiefs are a new type of cleaning paper, functioning similarly to traditional handkerchiefs for wiping. They are made of soft paper. Due to their small size, portability, absorbency, and stain removal capabilities, paper handkerchiefs have brought great convenience to people's lives and have become a popular household item, loved by many consumers. Currently, the commonly used sizes of paper handkerchiefs on the market are generally quite fixed, and some packaging is even too large, making them inconvenient to carry. Consequently, the production equipment for paper handkerchiefs can only produce these fixed sizes or those close to them.

[0003] In the paper handkerchief folding process, existing technologies also have significant shortcomings in the trimming of excess paper edges. Traditional equipment often struggles to achieve precise positioning during trimming, resulting in uneven edges on the cut paper handkerchiefs, which severely affects the product's appearance quality. Moreover, many machines have fixed trimming dimensions and cannot be flexibly adjusted to meet the production needs of paper handkerchiefs of different sizes. When producing ultra-mini paper handkerchiefs of different sizes, it is necessary to change the corresponding trimming parts, which is cumbersome, time-consuming, and greatly reduces the continuity and efficiency of production. Summary of the Invention

[0004] To overcome the technical defects of existing technologies, this utility model provides an ultra-mini paper handkerchief folding and processing device. The guide block and guide strip work together to ensure that the cutting blade moves accurately along a predetermined trajectory; the pressing plate uses a spring to firmly press the paper and prevent displacement during cutting; the smoothing mechanism, including the smoothing plate, is equipped with adhesive strips to eliminate wrinkles, effectively avoiding cutting deviations and ensuring that the paper is of consistent size and has smooth edges after cutting, meeting the high requirements of cutting accuracy and appearance for ultra-mini paper handkerchiefs. The transmission roller group and the conveying roller group form a stable path for paper feeding, the hydraulic rod drives the cutting blade to cut efficiently, and the spring helps the smoothing plate to quickly return to its original position. The cooperation of each mechanism shortens the process interval; the bolt-connected cutting blade is easy to replace and adapts to different cutting requirements, eliminating the need for long-term downtime, improving cutting efficiency, and reducing labor costs. The pressing plate buffers and prevents the paper from wrinkling or breaking, and the soft adhesive strips prevent scratches, ensuring the integrity and soft texture of the paper after cutting.

[0005] The technical solution adopted by this utility model is: an ultra-mini paper handkerchief folding and processing equipment, including a frame. A drive roller assembly and a folding machine body are mounted on the surface of the frame. The drive roller assembly transports the cut paper to the folding machine body for folding. A cover is fixed to the surface of the frame, and a hydraulic rod is mounted on the surface of the cover. The piston end of the hydraulic rod extends into the cover and connects to a connecting plate located inside the cover. Mounting plates are symmetrically fixed to the surface of the connecting plate, and a cutting blade is bolted to the surface of the mounting plate. The drive roller assembly precisely delivers the cut paper to the folding machine, connecting the cutting and folding processes, avoiding transport confusion, and improving production continuity and efficiency. The cover protects the internal cutting components, reducing external interference and lowering operational safety risks. The hydraulic rod provides stable and controllable power to the cutting blade, which is transmitted through the connecting plate and mounting plate to precisely control the cutting force and stroke, ensuring stable cutting results. The mounting plate is bolted to the cutting blade, facilitating replacement as needed, enhancing the equipment's versatility and flexibility, and reducing maintenance costs and time.

[0006] Preferably, a bottom cutting plate is installed on the inner bottom surface of the shell. The surface of the bottom cutting plate is provided with a cutting groove that is compatible with the cutting blade. During cutting, the cutting blade can be fully inserted into the cutting groove, so that the edge of the paper is completely cut off. This avoids problems such as rough and uneven paper edges caused by incomplete cutting, ensuring the smoothness and aesthetics of the edges of the ultra-mini paper handkerchief and improving product quality.

[0007] Preferably, a guide block is fixedly installed on the surface of the mounting plate, and a guide strip is slidably connected to the surface of the guide block. The guide strip is fixedly installed on the inner side wall of the housing, providing precise guidance for the up and down movement of the mounting plate, effectively preventing the mounting plate from shifting or shaking during movement, and ensuring that the paper size is consistent each time it is cut.

[0008] Preferably, a conveyor roller assembly is fixedly installed on one side of the housing, and a conveyor roller assembly is installed on the inner bottom surface of the housing. The conveyor roller assembly is used to convey the raw material paper into the housing and, together with the conveyor roller assembly, realizes the cutting and conveying of the raw material paper within the housing. This can effectively control the paper's conveying speed and tension, avoid problems such as wrinkles, deviations, or stretching deformation of the paper during the conveying process, ensure the paper's flatness before cutting, lay a good foundation for subsequent precise cutting, and thus improve the product's qualification rate.

[0009] Preferably, a T-shaped connecting rod is slidably connected within the ventilation holes on the surface of the mounting plate. A pressing plate is fixed to one end of the T-shaped connecting rod, and a spring is sleeved on the surface of the T-shaped connecting rod. One end of the spring abuts against the surface of the pressing plate, and the other end of the spring abuts against the bottom surface of the mounting plate. Before cutting, the pressing plate contacts the paper first. Under the elastic action of the spring, the paper can be pressed tightly against the bottom cutting plate, effectively preventing the paper from shifting due to force during the cutting process and ensuring the accuracy of the cutting position.

[0010] Preferably, two T-shaped connecting rods are symmetrically installed on one side surface of the mounting plate. Connecting blocks are slidably connected to the surfaces of both T-shaped connecting rods. A smoothing plate is installed on the surface of each connecting block. A T-shaped rod is fixedly installed on one side surface of each connecting block. One end of the T-shaped rod is slidably connected to an L-shaped groove on the inner wall of the housing. When the mounting plate moves up and down, the T-shaped rod slides within the L-shaped groove, causing the connecting blocks and smoothing plate to move back and forth. This fully smooths the paper surface, ensuring a flat and wrinkle-free surface before cutting, avoiding dimensional deviations caused by paper wrinkles, further improving cutting accuracy, and making the ultra-mini paper handkerchiefs more uniform in appearance.

[0011] Preferably, a second spring is fitted on the outer surface of the T-shaped connecting rod. One end of the second spring abuts against one side of the connecting block, and the other end of the second spring abuts against the T-shaped structure of the T-shaped connecting rod. When the smoothing plate moves forward to smooth the paper, the second spring is compressed and accumulates elastic potential energy. After cutting, under the elastic force of the second spring, the connecting block drives the smoothing plate to quickly return to its original position, preparing for the next smoothing action. This ensures the continuous working performance of the smoothing mechanism and improves the working efficiency of the equipment.

[0012] Preferably, a telescopic rod is installed on the bottom surface of the flat surface, and an abutting slide is fixed to the other end of the telescopic rod. A spring is sleeved on the outer surface of the telescopic rod, and an adhesive strip is installed on the side of the bottom surface of the abutting slide that contacts the paper to be processed. The adhesive strip increases the friction between the paper and the adhesive strip, which can more effectively eliminate wrinkles on the paper surface. At the same time, the adhesive strip is soft and avoids scratching the paper surface, protecting the soft texture and appearance quality of the paper, so that the produced ultra-mini paper handkerchiefs meet the high-quality requirements.

[0013] The beneficial effects of this utility model are: the sliding cooperation between the guide block and the guide strip ensures that the cutting blade moves along the predetermined trajectory; the pressing plate presses the paper firmly under the action of the spring to prevent displacement during cutting; the smoothing mechanism composed of the smoothing plate and the adhesive strip eliminates paper wrinkles, effectively avoiding cutting deviations, ensuring that the paper size is consistent each time it is cut, and that the edges are smooth and neat, thus meeting the strict requirements of ultra-mini paper handkerchiefs for dimensional accuracy and appearance.

[0014] The transmission roller group and the conveyor roller group work together to form a stable transmission path. The hydraulic rod drives the cutting knife to cut efficiently, and the spring makes the flat plate return quickly. The coordinated work of each mechanism reduces the process interval. At the same time, the bolt-connected cutting knife is easy to replace quickly and adapts to different specifications of production. It does not require long-term downtime for adjustment, which greatly improves the overall production efficiency and reduces labor costs.

[0015] The pressure plate's cushioning action prevents the paper from wrinkling or breaking, while the soft adhesive strip prevents scratches on the paper surface, ensuring the paper's integrity and soft texture. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] As shown in Figures 1-8, this embodiment provides an ultra-mini paper handkerchief folding processing device, including a frame 1. A transmission roller group 2 and a folding machine body 3 are installed on the surface of the frame 1. The transmission roller group 2 is used to transport the cut paper to the folding machine body 3 for folding processing. A shell 4 is fixed on the surface of the frame 1. A hydraulic rod 5 is installed on the surface of the shell 4. The piston end of the hydraulic rod 5 extends into the shell 4 and is connected to a connecting plate 8 set inside the shell 4. A mounting plate 9 is symmetrically fixed on the surface of the connecting plate 8. A cutting blade 10 is bolted to the surface of the mounting plate 9.

[0027] The transmission roller group 2 precisely transports the cut paper to the folding machine body 3, realizing the orderly connection between the cutting and folding processes, avoiding chaos in the paper transmission process, and improving the continuity and efficiency of production. The shell 4 provides effective protection for the internal cutting components, reducing the interference of external dust and impurities on the cutting process, and also reducing the safety risks of operators coming into contact with the cutting components. The hydraulic rod 5 provides stable and controllable power to the cutting blade 10. Through the transmission of the connecting plate 8 and the mounting plate 9, the cutting force and stroke of the cutting blade 10 can be precisely controlled to ensure stable cutting results. The mounting plate 9 is bolted to the cutting blade 10, which facilitates quick replacement of the cutting blade 10 according to the needs of different sizes of ultra-mini paper handkerchiefs, enhancing the versatility and flexibility of the equipment, and reducing the maintenance cost and time of the equipment.

[0028] Furthermore, a bottom cutting plate 27 is installed on the inner bottom surface of the housing 4, and a cutting groove 16 adapted to the cutting blade 10 is opened on the surface of the bottom cutting plate 27.

[0029] The cutting groove 16 on the surface of the bottom cutting plate 27 is adapted to the cutting blade 10. During cutting, the cutting blade 10 can be fully inserted into the cutting groove 16, so that the edge of the paper is completely cut off. This avoids problems such as rough and uneven paper edges caused by incomplete cutting, ensuring the smoothness and aesthetics of the edges of the ultra-mini paper handkerchief and improving product quality.

[0030] Furthermore, a guide block 11 is fixedly installed on the surface of the mounting plate 9, and a guide strip 12 is slidably connected to the surface of the guide block 11. The guide strip 12 is fixedly installed on the inner side wall of the housing 4.

[0031] The guide block 11 on the mounting plate 9 slides in conjunction with the guide strip 12 on the inner side wall of the housing 4, providing precise guidance for the up and down movement of the mounting plate 9. This effectively prevents the mounting plate 9 from shifting or shaking during movement, ensuring that the cutting blade 10 always stays on the predetermined cutting trajectory, improving the cutting accuracy and ensuring that the paper size is consistent each time it is cut.

[0032] Furthermore, a transfer roller group 6 is fixedly installed on one side of the housing 4, and a conveying roller group 7 is installed on the inner bottom surface of the housing 4. The transfer roller group 6 is used to transfer the raw material paper into the housing 4, and cooperates with the conveying roller group 7 to realize the cutting and transfer of the raw material paper in the housing 4.

[0033] The conveyor roller group 6 smoothly transports the raw paper into the housing 4, and the conveyor roller group 7 cooperates in the conveying inside the housing 4, forming a continuous paper conveying path. This effectively controls the paper conveying speed and tension, avoiding problems such as wrinkles, deviations or stretching deformation of the paper during the conveying process. This ensures that the paper is in a flat state before cutting, laying a good foundation for subsequent precise cutting, and thus improving the product qualification rate.

[0034] Furthermore, a T-shaped connecting rod 14 is slidably connected in the ventilation holes opened on the surface of the mounting plate 9. One end of the T-shaped connecting rod 14 is fixed with a pressing plate 13. A spring 15 is sleeved on the surface of the T-shaped connecting rod 14. One end of the spring 15 abuts against the surface of the pressing plate 13, and the other end of the spring 15 abuts against the bottom surface of the mounting plate 9.

[0035] Before cutting, the pressing plate 13 first contacts the paper. Under the elastic action of the spring 15, the paper can be pressed tightly onto the bottom cutting plate 27, effectively preventing the paper from shifting due to force during the cutting process and ensuring the accuracy of the cutting position.

[0036] Furthermore, two T-shaped connecting rods 17 are symmetrically installed on one side surface of the mounting plate 9. Connecting blocks 19 are slidably connected to the surfaces of the two T-shaped connecting rods 17. The same flat plate 22 is installed on the surfaces of the two connecting blocks 19. A T-shaped rod 20 is fixedly installed on one side surface of the connecting block 19. One end of the T-shaped rod 20 is slidably connected to the L-shaped inclined groove 21 opened in the inner side wall of the housing 4.

[0037] When the mounting plate 9 moves up and down, the T-shaped rod 20 slides in the L-shaped inclined groove 21, driving the connecting block 19 and the smoothing plate 22 to move back and forth, which can fully smooth the paper surface, ensuring that the paper surface is flat and wrinkle-free before cutting, avoiding cutting size deviation caused by paper wrinkles, further improving cutting accuracy, and making the appearance of the ultra-mini paper handkerchief more regular.

[0038] Furthermore, a second spring 18 is fitted on the outer surface of the T-shaped connecting rod 17. One end of the second spring 18 abuts against one side of the connecting block 19, and the other end of the second spring 18 abuts against the T-shaped structure of the T-shaped connecting rod 17.

[0039] As the smoothing plate 22 moves forward to smooth the paper, the second spring 18 is compressed, accumulating elastic potential energy. After the cutting is completed, under the elastic force of the second spring 18, the connecting block 19 drives the smoothing plate 22 to quickly return to its original position, preparing for the next smoothing action. This ensures the continuous working performance of the smoothing mechanism and improves the working efficiency of the equipment.

[0040] Furthermore, a telescopic rod 23 is installed on the bottom surface of the flat plate 22, and an abutting slide plate 25 is fixed to the other end of the telescopic rod 23. A spring 24 is sleeved on the outer surface of the telescopic rod 23, and an adhesive strip 26 is installed on the side of the bottom surface of the abutting slide plate 25 that contacts the paper to be processed.

[0041] The adhesive strip 26 increases the friction between the adhesive strip and the paper, which can more effectively eliminate wrinkles on the paper surface. At the same time, the adhesive strip 26 is soft and avoids scratching the paper surface, protecting the soft texture and appearance quality of the paper, making the produced ultra-mini paper handkerchiefs more in line with high-quality requirements.

[0042] It should be noted that the telescopic rod 23 is composed of two rods with different diameters, with the smaller diameter rod slidingly connected inside the larger diameter rod.

[0043] Working principle: The conveyor roller group 6 transports the raw paper into the housing 4. After entering the housing 4, under the synergistic action of the conveyor roller group 7, the paper is stably transported in the housing 4 according to the set speed and path, preparing for the subsequent cutting work.

[0044] Next, the cutting process begins. When the paper is transferred to the cutting position, the hydraulic rod 5 is activated, and its piston end pushes the connecting plate 8 to move downward. The connecting plate 8 drives the mounting plate 9 and the cutting blade 10 mounted on the mounting plate 9 to move downward together. During this process, the guide block 11 on the surface of the mounting plate 9 slides along the guide strip 12 on the inner side wall of the housing 4 to ensure that the cutting blade 10 moves smoothly in the vertical direction.

[0045] Meanwhile, as the mounting plate 9 moves down, the pressing plate 13 at one end of the T-shaped connecting rod 14 first contacts the paper. Under the elastic action of the spring 15, the pressing plate 13 presses the paper tightly onto the bottom cutting plate 27 to prevent the paper from shifting during the cutting process. At the same time, the T-shaped rod 20 on one side of the mounting plate 9 slides in the L-shaped inclined groove 21. With the cooperation of the spring 28, it drives the connecting block 19 and the smoothing plate 22 to move. The abutting slide plate 25 on the bottom surface of the smoothing plate 22, under the action of the telescopic rod 23 and the spring 3 24, makes close contact with the paper surface through the adhesive strip 26 to smooth the paper and ensure that the paper surface is flat and wrinkle-free.

[0046] Subsequently, the cutting blade 10 continues to move downwards, cooperating with the cutting groove 16 on the surface of the bottom cutting plate 27 to complete the precise cutting of the excess edges of the paper. After the cutting is completed, the hydraulic rod 5 drives the connecting plate 8, the mounting plate 9 and the cutting blade 10 to return to the starting position. The pressing plate 13 and the flat plate 22 also return to their initial positions under the action of the corresponding springs, preparing for the next cutting.

[0047] Finally, in the folding stage, the cut paper is accurately transported into the folding machine body 3 by the conveyor roller group 2. The folding machine body 3 folds the paper according to the preset folding program, and finally forms an ultra-mini paper handkerchief.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
