[0020] The following is combined with Figure 1-Figure 2 This application is described in further detail.
[0021] The present application embodiment discloses a straw forming module. Figure 1 and Figure 2 The straw forming module includes a connecting frame 1, an outer sleeve 2, an inner sleeve 3 and a hot pressing forming assembly 4. The connecting frame 1 is used to support the outer sleeve 2. The inner sleeve 3 is located inside the outer sleeve 2 to cooperate with the outer sleeve 2 to guide and form the paper. The hot pressing forming assembly 4 is installed in the middle of the outer sleeve 2 and the inner sleeve 3. The hot pressing forming assembly 4 is used to horizontally transport the paper and press the overlapping edges of the paper.
[0022] Specifically, the connecting frame 1 is formed by splicing a number of bearings 11. In this embodiment, there are four bearings 11, which are arranged in a matrix. The outer edges of the bearings 11 are formed. Therefore, the four bearings 11 can be spliced together to form a positioning groove 111. The positioning groove 111 is cylindrical. The outer sleeve 2 is plugged into the positioning groove 111, and the outer wall of the outer sleeve 2 abuts against the inner wall of the positioning groove 111 to fix the outer sleeve 2.
[0023] Therefore, the structural design of the connecting frame 1 further enhances the stability and precision of the straw forming module. Specifically, the connecting frame 1 is formed by four bearings 11 arranged in a matrix, and their outer edges are specially molded so that the four bearings 11 can fit tightly together to form a cylindrical positioning groove 111.
[0024] At the same time, the outer sleeve 2 and the positioning groove 111 are plug-fitted, that is, the outer wall of the outer sleeve 2 abuts against the groove wall of the positioning groove 111, ensuring that the outer sleeve 2 is firmly fixed during operation, reducing the displacement caused by vibration or external force, and thus ensuring the accuracy and consistency of the straw forming process.
[0025] In addition, the matrix arrangement of the bearings 11 and the cylindrical design of the positioning grooves 111 can effectively disperse the pressure on the outer sleeve 2 during operation, extend the service life of the entire straw forming module, and further improve production efficiency and product quality.
[0026] Furthermore, a transverse tube 12 is provided on the bearing 11 , and the transverse tube 12 is used to be connected to an external device to realize the installation of the straw forming module. There are four transverse tubes 12 , and the four transverse tubes 12 are respectively and sequentially fixed vertically to the four bearings 11 .
[0027] Therefore, the transverse tube 12 is arranged perpendicular to the bearing 11, forming a stable support frame. The transverse tube 12 not only connects to external equipment, enabling rapid installation and removal of the straw forming module, but also withstands the forces transmitted by external equipment, ensuring the stability and reliability of the entire straw forming module during operation.
[0028] In addition, the design of the transverse tube 12 also takes into account the optimization of spatial layout. The four transverse tubes 12 are respectively connected to the four bearings 11 to form an evenly distributed support structure, which effectively disperses the concentrated load on the interface of external equipment and reduces structural deformation or damage caused by excessive local force, thereby ensuring the performance stability and service life of the straw forming module under long-term continuous operation.
[0029] On the other hand, the outer sleeve 2 is sleeved on the outside of the inner sleeve 3, and a forming groove 5 is formed between the inner wall of the outer sleeve 2 and the inner wall of the inner sleeve 3. The hot pressing forming assembly 4 includes a driving motor 41, a hot pressing roller 42 and a driven roller 43. The driving motor 41 is installed on the outside of the outer sleeve 2 and is fixed to one of the bearings 11. The hot pressing roller 42 is coaxially fixed to the output shaft of the driving motor 41. The driven roller 43 rotates and is supported by the inner wall of the inner sleeve 3. The hot pressing roller 42 and the driven roller 43 are parallel to each other. At the same time, the outer sleeve 2 and the inner sleeve 3 are both provided with a clearance groove 6, which is connected to the forming groove 5. The clearance groove 6 is for the hot pressing roller 42 and the driven roller 43 to make way, and the gap formed between the hot pressing roller 42 and the driven roller 43 is located in the forming groove 5.
[0030] Correspondingly, after the paper is inserted from one end of the forming groove 5, the forming groove 5 shapes the paper. When the paper passes through the hot pressing roller 42 and the driven roller 43, the corresponding control drive motor 41 is started, and the hot pressing roller 42 rotates under the drive of the motor and cooperates with the driven roller 43 to apply heat and pressure to the paper material in the forming groove 5, while providing power for conveying the paper.
[0031] Therefore, the outer sleeve 2 is mounted on the outside of the inner sleeve 3, and the forming groove 5 formed between the two is the key area for straw forming. The hot press forming assembly 4 includes a drive motor 41, a hot press roller 42, and a driven roller 43. The drive motor 41 is mounted on the outside of the outer sleeve 2 and fixed to one of the bearings 11, ensuring the stability and accuracy of the motor's operation.
[0032] At the same time, the hot pressing roller 42 is coaxially fixed to the output shaft of the driving motor 41, and the driven roller 43 is rotated and carried on the inner wall of the inner sleeve 3. The two are parallel to each other and act together on the paper material in the forming groove 5 to realize the forming of the straw through hot pressing.
[0033] Furthermore, both the outer sleeve 2 and the inner sleeve 3 are provided with clearance grooves 6, which communicate with the forming grooves 5. These clearance grooves 6 provide the necessary space for the movement of the hot-pressing roller 42 and the driven roller 43, ensuring that the gap between them is precisely positioned within the forming grooves 5, thereby guaranteeing dimensional accuracy and surface quality during the straw forming process. Furthermore, the design of the clearance grooves 6 effectively reduces interference between the hot-pressing roller 42 and the driven roller 43 during operation, thereby improving the operating efficiency and reliability of the entire forming module.
[0034] In this embodiment, the drive motor 41 is a servo motor, and the surface of the hot pressing roller 42 is provided with a heating layer, which is heated by electric heating wires. The servo motor has the characteristics of high precision, fast response speed and good control performance. It can accurately control the rotation speed and position of the hot pressing roller 42, ensuring the stability and accuracy of the straw forming process. At the same time, the surface of the hot pressing roller 42 is provided with a heating layer, which is heated by electric heating wires. The heat generated by the electric heating wires evenly heats the surface of the hot pressing roller 42, ensuring that a constant temperature can be provided during the hot pressing process, thereby ensuring the quality of the straw forming. The electric heating wire heating method has the advantages of uniform heating, accurate temperature control and low energy consumption, and can effectively improve the efficiency of hot pressing and the quality of the straw products.
[0035] Furthermore, one end of both the outer sleeve 2 and the inner sleeve 3 expands outward, with the expanded end serving as the paper feed port. This expanded end provides a wider entry point for the paper, reducing resistance as it enters the forming module and minimizing wrinkles or deviations during the introduction process, ensuring smooth straw forming and precise paper positioning.
[0036] In addition, a fixing block 7 is provided between the outer sleeve 2 and the inner sleeve 3. The fixing block 7 is located at one end where the outer sleeve 2 and the inner sleeve 3 are expanded. The fixing block 7 is fixed to the inner wall of the outer sleeve 2 and the outer wall of the inner sleeve 3 respectively.
[0037] Correspondingly, the inlet end of the inner sleeve 3 and the inlet end of the outer sleeve 2 are both large-diameter. At this time, the two sides of the paper are not rolled to overlap, so there is a space here and it will not interfere with the paper. Then, a fixing block 7 is used to fix the inner sleeve 3 and the outer sleeve 2 together.
[0038] The implementation principle of the straw forming module in the embodiment of the present application is as follows:
[0039] Through automated winding and hot pressing technology, efficient forming of paper and continuous production of straws are achieved. Specifically, the outer sleeve 2 and the inner sleeve 3 in the straw forming module form a forming groove 5 for forming the paper. The hot pressing forming component 4 transports the paper in the horizontal direction and presses the overlapping edges of the paper to achieve automatic winding and pressing of the paper to form cylindrical straws. The hot pressing roller 42 and the driven roller 43 in the hot pressing component cooperate with each other to apply hot pressing to the paper to ensure the structural stability and sealing of the straws. This automated process significantly improves production efficiency. At the same time, the precise control of the hot pressing component 4 ensures the dimensional accuracy and surface quality of the straws, meeting the market's high requirements for product quality.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
