Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and in particular to a novel four-sided embossed structure for tissue paper. Background Technology

[0002] As a commonly used cleaning product in daily life, paper towels have received much attention for their convenience and practicality. Currently, paper towels on the market usually use an embossing process to improve their texture and strength. In the embossing process, an embossing roller is used, which is a roller with a patterned outer wall that comes into contact with the paper to compress and shape it.

[0003] When using existing embossing rollers, it is often necessary to select appropriate sized embossing rollers and splice them together according to the different embossing positions and lengths to achieve the extrusion and shaping of paper. However, after multiple embossing rollers are spliced ​​together, due to the lack of an effective support and guiding structure inside, when the pressure on a single embossing roller increases, it will inevitably cause the connection between the multiple embossing rollers to deform, affecting the embossing effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing embossing rollers, when used, often require selecting appropriate-sized embossing rollers and splicing them together to extrude and shape the paper, depending on the embossing position and length. However, after multiple embossing rollers are spliced ​​together, due to the lack of an effective internal support and guiding structure, when the pressure on a single embossing roller increases, it inevitably leads to deformation of the connection between the multiple embossing rollers, affecting the embossing effect. Therefore, a new four-sided embossing structure for tissue paper is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel four-sided embossed structure for tissue paper includes a mounting base. A support mechanism is installed inside the mounting base. The support mechanism includes a limiting block embedded within the mounting base. A positioning mechanism is installed inside the limiting block. The positioning mechanism includes a bearing shaft, a positioning groove, and positioning guide strips. The positioning groove is formed on the outer wall of the bearing shaft, and the bearing shaft is embedded in the limiting block through the positioning groove on its outer wall. The positioning guide strips are designed to protrude from the outer circumference of the bearing shaft. Four positioning guide strips are arranged in a circular array and fixedly disposed on the outer wall of the bearing shaft. An embossing mechanism is installed on the outer side of the bearing shaft.

[0007] Preferably, the embossing mechanism includes a connecting sleeve and a constricted connector. The main body of the connecting sleeve is a tubular structure that runs through both the left and right sides. The connecting sleeve is sleeved on the outer wall of the bearing shaft, and the constricted connector is fixedly installed on the outer wall of the connecting sleeve.

[0008] Preferably, the constricted nozzle is in communication with the connecting sleeve, and the diameter of the constricted nozzle is smaller than the diameter of the connecting sleeve.

[0009] Preferably, the embossing mechanism further includes a positioning slot, which is formed on the inner wall of the connecting sleeve and the constricted pipe, and the positioning slot matches the positioning guide strip.

[0010] Preferably, both the connecting sleeve and the constricted tube are fitted onto the outer wall of the positioning guide strip through positioning slots. The embossing mechanism also includes an assembly groove, which is an annular structure and is located on the outer wall of the constricted tube.

[0011] Preferably, the embossing mechanism further includes a positioning screw hole and a fixing bolt, wherein the positioning screw hole is opened on the outer wall of the connecting sleeve, and the fixing bolt is fixedly disposed in the positioning screw hole.

[0012] Preferably, the fixing bolt is used to limit the position of the connecting sleeve on the outer wall of the bearing shaft, the connecting sleeve is in the state of being sleeved on the outer wall of the bearing shaft, and the fixing bolt is in the state of abutting against the outer wall of the bearing shaft.

[0013] Preferably, the support mechanism further includes a mounting plate and a mounting hole. The mounting plate is fixedly disposed on the outer wall of the mounting base, and the mounting hole is opened in the mounting plate. The mounting base and the mounting plate together form a support structure for the bearing shaft. The outer wall of the assembly groove is equipped with an embossing bearing in the embossing mechanism, and an embossing roller is installed through the embossing bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By incorporating components such as mounting bases, limit blocks, and bearing shafts, the mounting bases and limit blocks work together to provide stable support for the bearing shaft. The bearing shaft, in turn, provides an installation reference for the embossing mechanism via positioning guide strips. This ensures that multiple embossing-related components have a reliable support foundation after assembly, effectively avoiding the deformation problems of embossing components caused by insufficient support in existing technologies, and guaranteeing structural stability during the embossing process. Furthermore, by incorporating components such as positioning guide strips, positioning slots, and fixing bolts, the precise matching of the positioning guide strips and positioning slots enables rapid positioning and assembly of the embossing mechanism. The fixing bolts further limit the connection of the sleeve. This design ensures the coaxiality and positional stability of multiple embossing rollers after splicing, reduces component misalignment during embossing, and improves the precision and consistency of tissue paper embossing. Through the overall linkage of the support mechanism, positioning mechanism, and embossing mechanism, the mounting base provides fixed support, the limit block restricts the rotation of the bearing shaft, the positioning guide strip achieves precise positioning, and the embossing rollers operate smoothly through the embossing bearings. This allows the device to maintain good structural stability and embossing effect when splicing components to meet different embossing requirements, solving the problem of pressure affecting the embossing effect after splicing in existing technologies, and improving the applicability and embossing quality of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example, refer to Figure 1 - Figure 6 A novel four-sided embossed structure for tissue paper includes a mounting base 1. A support mechanism is installed inside the mounting base 1. The support mechanism includes a limiting block 1012, which is embedded in the mounting base 1. A positioning mechanism is installed inside the limiting block 1012. The positioning mechanism includes a bearing shaft 2, a positioning groove 201, and a positioning guide strip 2011. The positioning groove 201 is formed on the outer wall of the bearing shaft 2. The bearing shaft 2 is embedded in the limiting block 1012 through the positioning groove 201 formed on its outer wall. The positioning guide strip 2011 protrudes from the bearing shaft 2. The outer peripheral structure design includes four positioning guide strips 2011, which are fixedly arranged in a circular array on the outer wall of the bearing shaft 2. An embossing mechanism is installed on the outer side of the bearing shaft 2. The bearing shaft 2 is supported by the limiting block 1012 inside the mounting base 1. The positioning groove 201 on the outer wall of the bearing shaft 2 is used for assembly with the limiting block 1012. The four circular array of positioning guide strips 2011 provides positioning and guidance for the outer embossing mechanism, effectively preventing deformation due to lack of support and guidance after multiple embossing parts are spliced ​​together, thus ensuring the embossing effect.

[0025] Furthermore, the embossing mechanism includes a connecting sleeve 3 and a constricted tube 301. The main body of the connecting sleeve 3 is a tubular structure that runs through both the left and right sides. The connecting sleeve 3 is sleeved on the outer wall of the bearing shaft 2, and the constricted tube 301 is fixedly installed on the outer wall of the connecting sleeve 3. By sleeved on the outer wall of the bearing shaft 2 and fixed on the outer wall of the connecting sleeve 3, the basic assembly structure of the embossing mechanism is constructed, realizing a stable connection between the embossing mechanism and the bearing shaft 2, and providing a reliable carrier for the subsequent installation of embossed components.

[0026] Furthermore, the constricted nozzle 301 is connected to the connecting sleeve 3. The diameter of the constricted nozzle 301 is smaller than the diameter of the connecting sleeve 3. This clarifies that the constricted nozzle 301 is connected to the connecting sleeve 3 and has a smaller diameter, thus optimizing the structural size ratio of the embossing mechanism. This reduces the overall space occupied and enhances the structural strength of the constricted nozzle 301, ensuring the stability after assembly.

[0027] Furthermore, the embossing mechanism also includes a positioning slot 3012, which is formed on the inner wall of the connecting sleeve 3 and the constricted tube 301. The positioning slot 3012 matches the positioning guide strip 2011. The positioning slot 3012, which matches the positioning guide strip 2011, is formed on the inner wall of the connecting sleeve 3 and the constricted tube 301 to ensure that the connecting sleeve 3 and the constricted tube 301 can accurately fit the positioning guide strip 2011 during installation, avoid installation misalignment, and improve the positioning accuracy of the embossing mechanism.

[0028] Furthermore, both the connecting sleeve 3 and the constricted tube 301 are fitted onto the outer wall of the positioning guide strip 2011 through the positioning slot 3012. The embossing mechanism also includes an assembly groove 3011, which is an annular structure and is located on the outer wall of the constricted tube 301. The positioning slot 3012 securely fits the connecting sleeve 3 and the constricted tube 301 onto the outer wall of the positioning guide strip 2011. The assembly groove 3011 on the outer wall of the constricted tube 301 is used to install the embossing bearing 3016 and the embossing roller 3015, thereby achieving stable assembly of the embossing roller 3015. At the same time, the support of the positioning guide strip 2011 prevents the embossing roller 3015 from deforming under pressure.

[0029] Furthermore, the embossing mechanism also includes a positioning screw hole 3013 and a fixing bolt 3014. The positioning screw hole 3013 is opened on the outer wall of the connecting sleeve 3, and the fixing bolt 3014 is fixedly installed in the positioning screw hole 3013. The positioning screw hole 3013 and the fixing bolt 3014 are opened on the outer wall of the connecting sleeve 3, providing an adjustable fixing structure for the connecting sleeve 3, which is convenient for adjusting the position of the connecting sleeve 3 according to the embossing requirements and then fixing it.

[0030] Furthermore, the fixing bolt 3014 is used to limit the position of the connecting sleeve 3 on the outer wall of the bearing shaft 2. When the connecting sleeve 3 is sleeved on the outer wall of the bearing shaft 2, the fixing bolt 3014 is in abutting against the outer wall of the bearing shaft 2. By the fixing bolt 3014 abutting against the outer wall of the bearing shaft 2, the position of the connecting sleeve 3 on the outer wall of the bearing shaft 2 is limited and locked, preventing the connecting sleeve 3 from sliding during the embossing operation and ensuring the stability of the embossing mechanism.

[0031] Furthermore, the support mechanism also includes a mounting plate 101 and a mounting hole 1011. The mounting plate 101 is fixedly disposed on the outer wall of the mounting base 1, and the mounting hole 1011 is opened in the mounting plate 101. The mounting base 1 and the mounting plate 101 together form a support structure for the bearing shaft 2. The outer wall of the assembly groove 3011 is equipped with an embossing bearing 3016 in the embossing mechanism, and an embossing roller 3015 is installed through the embossing bearing 3016. Through the mounting plate 101 and the mounting hole 1011 on the outer wall of the mounting base 1, together with the mounting base 1, they form a support structure for the bearing shaft 2, which enhances the support strength of the bearing shaft 2, improves the overall stability of the entire embossing structure, and provides reliable support for the embossing operation.

[0032] When in use, firstly, with the help of the mounting plate 101 fixed on the outer wall of the mounting base 1, the external fastening parts are passed through the mounting holes 1011 opened on the mounting plate 101, and the mounting plate 101 and the mounting base 1 are fixed together in the designated working area of ​​the tissue paper production equipment. This provides a stable installation foundation for the entire new tissue paper four-sided embossing structure, preventing the structure from shaking or shifting during subsequent embossing operations.

[0033] Next, align the bearing shaft 2 with the limiting block 1012 embedded inside the mounting base 1, so that the positioning groove 201 on the outer wall of the bearing shaft 2 is precisely fitted and aligned with the inner wall of the limiting block 1012. Then, slowly insert the bearing shaft 2 into the limiting block 1012. At this time, the limiting block 1012 will form a surrounding support for the bearing shaft 2, and at the same time, the limiting block 1012 will restrict the rotation of the bearing shaft 2, providing a basic guarantee for the power transmission of the subsequent embossing action.

[0034] Then, the embossing mechanism and the bearing shaft 2 are assembled. First, the positioning slots 3012 opened on the inner wall of the connecting sleeve 3 in the embossing mechanism are aligned one by one with the positioning guide strips 2011 distributed in a ring on the outer wall of the bearing shaft 2. Then, the connecting sleeve 3 is slowly fitted onto the outer wall of the bearing shaft 2 along the extension direction of the positioning guide strips 2011. Since the constriction tube 301 is fixedly set on the outer wall of the connecting sleeve 3, the constriction tube 301 will be connected to the bearing shaft 2 synchronously with the assembly of the connecting sleeve 3. During this process, the matching relationship between the positioning guide strips 2011 and the positioning slots 3012 will strictly limit the circumferential rotation of the connecting sleeve 3 to ensure that the embossing mechanism can maintain a synchronous rotation state with the bearing shaft 2 in the future.

[0035] After the connecting sleeve 3 is adjusted on the bearing shaft 2 to meet the requirements of the paper towel embossing, use a special tool to screw the fixing bolt 3014 in the positioning screw hole 3013 on the outer wall of the connecting sleeve 3, so that the fixing bolt 3014 moves along the axial direction of the positioning screw hole 3013 towards the bearing shaft 2 until the end of the fixing bolt 3014 is tightly connected to the outer wall of the bearing shaft 2. The squeezing force generated by the fixing bolt 3014 on the bearing shaft 2 will firmly lock the connecting sleeve 3 in the current position, so as to prevent the connecting sleeve 3 from sliding along the axial direction of the bearing shaft 2 due to pressure during subsequent embossing operations.

[0036] The embossing bearing 3016 is then embedded into the annular assembly groove 3011 on the outer wall of the tapered tube 301. The assembly groove 3011 will limit the embossing bearing 3016 in the radial direction to prevent the embossing bearing 3016 from shifting its position during rotation. Then, the embossing roller 3015 is sleeved onto the outer wall of the embossing bearing 3016. At this time, the embossing roller 3015 can rotate flexibly independently of the tapered tube 301 by taking advantage of the rotatable characteristic of the embossing bearing 3016, thus preparing for subsequent embossing with the tissue paper.

[0037] When the paper towel embossing operation is started, as the embossing material is fed, the embossing roller 3015 is driven to rotate by friction. At the same time, when the embossing roller 3015 comes into contact with the paper towel surface, it will rotate autonomously through the embossing bearing 3016 due to the friction generated by the paper towel and its own gravity. Finally, the four sides of the paper towel are squeezed and shaped by the pre-set pattern on the outer wall of the embossing roller 3015, thus completing the embossing and forming operation of the four sides of the paper towel.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
