Description

Technical Field

[0001] This utility model relates to the field of paper towel production mold technology, specifically to a paper towel production mold with a multi-layer absorbent structure. Background Technology

[0002] As an indispensable cleaning product in daily life, the absorbency of paper towels is one of the core indicators for measuring product quality. With the continuous improvement of consumers' requirements for the use experience of paper towels, paper towels with multi-layer absorbent structure have gradually become the mainstream products in the market due to their advantages such as large absorbency and fast absorption speed. These paper towels are usually made of multiple layers of substrate, and absorbent materials such as absorbent resin and fluff pulp are added to some substrate layers to further improve absorbency.

[0003] To improve the appearance of the surface paper of absorbent paper towels, it is usually necessary to emboss the surface paper of the paper towels. When embossing, corresponding embossing production molds are usually used.

[0004] For example, the utility model patent with authorization announcement number CN222844946U discloses an embossing device for tissue paper production, including a base and a frame. A connecting rod is installed inside the frame, a motor is installed on the frame, and an embossing component is installed on the connecting rod. The embossing component includes a fixed plate and an embossing rod. A support plate is fitted on the embossing rod, and two locking rods are installed on the support plate. When different shapes need to be embossed, simply rotate the locking rods. The first external thread and the first and second internal threads rotate helically. The two locking rods then spiral out from the fixed plate and the support plate in sequence. Then, rotate the embossing rod, and the second external thread and the third internal thread rotate helically. The embossing rod is removed from the fixed plate, and a new embossing rod is installed. Tissue paper can be embossed using only one embossing machine. Compared with the prior art, this utility model makes it more convenient to change the embossing mold and reduces the workload.

[0005] While the aforementioned technical solutions have their advantages, these embossing production molds also have some shortcomings in use. For example, they rely on the downward movement of an embossing rod to perform the embossing operation, meaning that only one pattern can be pressed out per operation, preventing continuous embossing and affecting production efficiency. Therefore, we propose a tissue paper production mold with a multi-layer absorbent structure. Utility Model Content

[0006] The purpose of this invention is to provide a paper towel production mold with a multi-layer absorbent structure to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A tissue paper production mold with a multi-layer absorbent structure includes a support platform. A support frame is detachably mounted on the top surface of the support platform. A cylinder is fixedly mounted on the top plate of the support frame. The telescopic shaft of the cylinder slides through the top plate of the support frame and detachably mounts a U-shaped frame. The U-shaped frame is slidably connected to the support frame. An embossing roller is rotatably connected between the front and rear plates of the U-shaped frame via a rotating shaft. A drive motor is coaxially mounted at the end of the embossing roller. End plates are fixedly mounted on the left and right sides of the top plate of the support frame. A storage box is fixedly mounted on the bottom plate of each end plate. A U-shaped slider is slidably connected inside the storage box. Multiple springs are fixedly mounted between the top plate of the U-shaped slider and the inner top wall of the storage box. A pressure roller is rotatably connected between the bottom of the front and rear plates of the U-shaped slider via a rotating shaft.

[0008] Preferably, the bottom of the support platform is fixedly equipped with multiple support legs, which are fixedly installed on the external frame.

[0009] Preferably, each end of the support platform is provided with two guide rollers distributed vertically. The guide rollers are rotatably connected to the external frame via a rotating shaft, and the two guide rollers are used for guiding the paper towels.

[0010] Preferably, sliding holes are provided on both the front and rear side plates of the support frame, and sliding plates are fixedly installed at both ends of the U-shaped frame. The sliding plates are located in the sliding holes and are slidably connected to the sliding holes. This feature guides the vertical movement of the U-shaped frame.

[0011] Preferably, both the slide plate and the sliding hole have rectangular cross-sections, and the size of the slide plate is adapted to the size of the sliding hole.

[0012] Preferably, side plates are fixedly installed at the bottom of the front and rear end plates of the support frame, and the side plates are detachably installed on the top surface of the support platform by multiple fastening bolts.

[0013] Preferably, the telescopic shaft of the cylinder is fixedly mounted with a rectangular plate, and the U-shaped frame is detachably mounted on the bottom surface of the rectangular plate.

[0014] Preferably, the bottom of the storage box has a storage chamber, the U-shaped slider is located in the storage chamber and is slidably connected to the storage chamber, and the two ends of the spring are respectively fixedly installed on the top surface of the U-shaped slider and the inner top wall of the storage chamber; This setting allows the pressure roller to adapt to the pressing operation of paper towels of different thicknesses.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of an embossing roller and a drive motor, in conjunction with the guide rollers at both ends of the support platform, realizes the continuous feeding and continuous embossing operation of paper towels on the mold. The drive motor drives the embossing roller to rotate continuously, while the guide rollers guide the multi-layer absorbent paper towels to pass smoothly between the embossing roller and the support platform. During the rotation of the embossing roller, the surface of the paper towel can be continuously embossed, which changes the limitation of single embossing of traditional molds, effectively improves the production efficiency of paper towel embossing, meets the needs of mass production, and solves the problem of low production efficiency in the existing technology.

[0016] 2. This utility model achieves precise adjustment and stable support of the embossing roller height through the combination of a cylinder, a U-shaped frame, and a sliding plate with a sliding hole. When the cylinder drives the U-shaped frame to move up and down, the sliding plate slides in the sliding hole, ensuring that the embossing roller always remains horizontal, avoiding uneven pattern depth caused by roller tilting during the embossing process. At the same time, the pressing roller in the storage box at the bottom of the end plate is always in contact with the surface of the tissue paper under the action of the spring, which can press the tissue paper in real time to prevent the tissue paper from shifting or wrinkling during the embossing process, ensuring the integrity and consistency of the embossed pattern, and improving the quality of the surface embossing of multi-layer absorbent tissue paper.

[0017] 3. This utility model achieves adaptive pressing of multi-layer absorbent paper towels of different thicknesses by using a sliding U-shaped slider connected to a spring-loaded pressing roller. When the paper towel thickness changes, the spring automatically extends and retracts according to the paper towel thickness, causing the U-shaped slider to slide up and down inside the storage box. This ensures that the pressing roller always adheres to the paper towel with appropriate force, avoiding damage to the paper towel structure due to excessive pressing force caused by excessively thick paper towels, and preventing insufficient pressing force due to excessively thin paper towels, which would affect the embossing effect. At the same time, the support frame can be detachably installed on the support platform via the side plate and fastening bolts, facilitating subsequent maintenance or replacement of the mold components and enhancing the flexibility and practicality of the mold.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a tissue paper production mold with a multi-layer absorbent structure, including a support platform 1, a support frame 2 detachably mounted on the top surface of the support platform 1, a cylinder 22 fixedly mounted on the top plate of the support frame 2, and a U-shaped frame 24 detachably mounted on the telescopic shaft of the cylinder 22 after sliding through the top plate of the support frame 2. The U-shaped frame 24 is slidably connected to the support frame 2, and an embossing roller 26 is rotatably connected between the front and rear plates of the U-shaped frame 24 via a rotating shaft. A drive motor 27 is coaxially mounted on one end of the embossing roller 26, enabling continuous and uninterrupted embossing of the tissue paper conveyed between the embossing roller 26 and the support platform 1 using the embossing roller 26, changing the traditional single-time embossing mode, greatly improving production efficiency, and meeting the needs of mass production. The drive motor 27 is fixedly mounted on the outer wall of one side plate of the U-shaped frame 24.

[0021] In this embodiment, end plates 3 are fixedly installed on both the left and right sides of the top plate of the support frame 2. A storage box 30 is fixedly installed on the bottom plate of each end plate 3. A U-shaped slider 32 is slidably connected to the inside of the storage box 30. Multiple springs 33 are fixedly installed between the top plate of the U-shaped slider 32 and the inner top wall of the storage box 30. A pressure roller 34 is rotatably connected between the bottom of the front and rear plates of the U-shaped slider 32 through a rotating shaft. The pressure roller 34 is always in contact with the surface of the tissue paper under the elastic force of the spring 33, and the tissue paper is pressed in real time to prevent the tissue paper from shifting or wrinkling during the embossing process and to ensure the integrity of the embossed pattern.

[0022] like Figure 1 As shown, multiple support legs 10 are fixedly installed at the bottom of the support platform 1. The support legs 10 are fixedly installed on the external frame, so that the support platform 1 can be stably installed on the production line, avoiding the mold from shaking during operation, providing a stable working platform for embossing operation, and reducing the impact of equipment shaking on embossing quality.

[0023] like Figure 1As shown, two guide rollers 11 are provided at both ends of the support platform 1, which are distributed vertically. The guide rollers 11 are rotatably connected to the external frame through a rotating shaft. The two guide rollers 11 are used to guide the paper towel, so that the multi-layer absorbent paper towel can be smoothly conveyed along the guide rollers 11 when entering and leaving the embossing area, avoiding jamming or deviation during the paper towel conveying process, ensuring that the paper towel is always in the correct embossing position, and improving the smoothness of the embossing operation.

[0024] like Figure 3 and Figure 4 As shown, sliding holes 20 are provided on both the front and rear sides of the support frame 2. Slide plates 25 are fixedly installed at both ends of the U-shaped frame 24. The slide plates 25 are located in the sliding holes 20 and are slidably connected to the sliding holes 20. The cross-sections of the slide plates 25 and the sliding holes 20 are both rectangular. The size of the slide plates 25 is adapted to the size of the sliding holes 20, so as to guide the up and down movement of the U-shaped frame 24.

[0025] Specifically, side plates 21 are fixedly installed at the bottom of the front and rear end plates of the support frame 2. The side plates 21 are detachably installed on the top surface of the support platform 1 by multiple fastening bolts, so that the support frame 2 can be easily disassembled or installed from the support platform 1, which facilitates the subsequent inspection or replacement of components such as the cylinder 22 and embossing roller 26 on the support frame 2, and reduces the difficulty of maintenance.

[0026] Furthermore, a rectangular plate 23 is fixedly installed on the telescopic shaft of the cylinder 22, and the U-shaped frame 24 is detachably installed on the bottom surface of the rectangular plate 23 by multiple fastening bolts, which facilitates the fixing, installation and disassembly of the U-shaped frame 24.

[0027] It is worth noting that the bottom of the storage box 30 has a storage chamber 31. The U-shaped slider 32 is located inside the storage chamber 31 and is slidably connected to the storage chamber 31. The two ends of the spring 33 are respectively fixedly installed on the top surface of the U-shaped slider 32 and the inner top wall of the storage chamber 31. When the thickness of the multi-layer absorbent tissue changes, the spring 33 can extend and retract to drive the U-shaped slider 32 to move up and down, so that the pressure roller 34 always adheres to the tissue with appropriate force, avoiding damage to the tissue due to excessive thickness or insufficient pressure on the tissue due to insufficient pressure, which would affect the embossing effect.

[0028] It is worth noting that the tissue paper passing between the upper and lower guide rollers 11 can be conveyed by an external conveying roller or an external retraction structure, so that the tissue paper can be conveyed normally.

[0029] Finally, it should be noted that the cylinder 22, drive motor 27, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0030] In use, the paper towel production mold with a multi-layer absorbent structure of this utility model lays one end of the paper towel on the top surface of the support platform 1 on the external feeding roller, and then wraps it around the take-up roller for winding. According to the thickness of the multi-layer absorbent paper towel, the cylinder 22 is activated to drive the U-shaped frame 24 to slide up and down along the sliding hole 20 and the sliding plate 25 to adjust the distance between the embossing roller 26 and the support platform 1; The drive motor 27 is started to drive the embossing roller 26 to rotate. One end of the tissue paper passes between the upper and lower guide rollers 11 at one end of the support platform 1. It is guided by the guide rollers 11 to the embossing roller 26 between the support platform 1. At this time, the pressing roller 34 in the storage box 30 is pressed against the surface of the tissue paper under the action of the spring 33 and the U-shaped slider 32. It rotates with the tissue paper and presses the tissue paper. The embossing roller 26 continues to emboss the surface of the tissue paper. The embossed tissue paper is output from the guide roller 11 at the other end of the support platform 1. After use, turn off the drive motor 27 and cylinder 22. If the embossing roller 26 needs to be replaced, the bolts on the rectangular plate 23 can be removed to take off the U-shaped frame 24. If maintenance is required, the bolts on the side plate 21 can be removed to remove the support frame 2. At the same time, the debris in the storage chamber 31 can be cleaned regularly to ensure smooth use next time.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
