DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0021] The present application embodiment discloses a high-speed single-slit water-based coating straw machine. Figure 1 The high-speed single-seam water-based coated straw machine includes a machine base 1, which is erected on the ground. The machine base 1 is respectively provided with an unwinding mechanism 2, a longitudinal die-cutting mechanism 3, a correcting mechanism 4, a traction mechanism 5, a forming mechanism 6 and a cutting mechanism 7. The unwinding mechanism 2 is used for unwinding paper, the longitudinal die-cutting mechanism 3 is used for longitudinally cutting the paper, the correcting mechanism 4 is for paper winding to adjust the paper conveying direction, the traction mechanism 5 cooperates with the unwinding mechanism 2 to realize horizontal conveying of paper, the forming mechanism 6 is used to wind the cut strip paper into straws, and the cutting mechanism 7 is used to cut paper to realize the output of straws.

[0022] Therefore, the unwinding mechanism 2 unwinds the large roll of paper smoothly, and then the longitudinal die-cutting mechanism 3 performs precise longitudinal cutting of the paper to form strips of paper. Next, the deviation correction mechanism 4 adjusts the conveying direction of the paper by winding it to ensure the precise positioning of the paper. The traction mechanism 5 works in conjunction with the unwinding mechanism 2 to achieve stable horizontal conveying of the paper. Subsequently, the forming mechanism 6 winds the cut strips of paper into shape to form the preliminary structure of the straws. Finally, the cutting mechanism 7 accurately cuts the formed straws to complete the final output of the straws. The entire process, through integrated design, realizes continuous and automated production from paper unwinding to straw output, significantly improves production efficiency, while effectively controlling production costs, providing an efficient and economical solution for the straw manufacturing industry.

[0023] Specifically, the unwinding mechanism 2 includes a bracket 21 and an unwinding shaft 22 rotatably connected to the bracket 21, the unwinding shaft 22 is used to put on the paper roll, the correction mechanism 4 includes a correction roller and a driving device, the driving device drives the correction roller to rotate to adjust the paper conveying direction, and the driving device is built into the base 1.

[0024] The unwinding shaft 22 is used to fit the paper roll of the large roll, ensuring that the paper is smoothly unwound during the unwinding process, providing continuous and stable paper materials for subsequent processing, and the driving device can accurately control the rotation of the correction roller, and fine-tune the paper conveying direction by adjusting the position and angle of the correction roller. The correction roller is usually designed to have a certain degree of elasticity, which can adapt to the slight fluctuation of the paper during the conveying process, ensuring that the paper maintains accurate alignment when entering the subsequent processing link, and avoiding processing errors caused by offset.

[0025] Furthermore, in other embodiments, the function of the deflection correction mechanism 4 can be further expanded, for example, by introducing sensors and control systems to realize intelligent operation of the deflection correction mechanism 4. The sensor can monitor the conveying state of the paper in real time, including parameters such as the position, tension and speed of the paper, and feed the data back to the control system. The control system automatically adjusts the output of the drive device according to the feedback information of the sensor, accurately controls the rotation of the deflection correction roller, realizes dynamic adjustment of the conveying direction of the paper, and ensures the accurate alignment of the paper during the entire processing process.

[0026] In addition, the correction mechanism 4 can also be equipped with an automatic cleaning device to regularly clean paper scraps and impurities on the correction roller to avoid a decrease in correction accuracy due to accumulation of impurities. The automatic cleaning device can be a brush, a scraper or a vacuum cleaner, etc., and a suitable cleaning method can be selected according to actual needs to ensure the long-term stable operation of the correction mechanism 4.

[0027] On the other hand, the longitudinal die-cutting mechanism 3 is located at the rear end of the unwinding mechanism 2, and the longitudinal die-cutting mechanism 3 is used to cut the paper longitudinally. Specifically, the paper is precisely cut longitudinally to form strips of paper in preparation for the subsequent straw forming. In order to further improve production efficiency and product quality, in this embodiment, the knife die of the longitudinal die-cutting mechanism 3 adopts a tool material with high hardness and high wear resistance to ensure that the die-cutting knife 72 can remain sharp after long-term work, reduce the frequency of tool replacement, and improve production continuity; equipped with an automatic alignment system, the edge of the paper is monitored in real time by a visual sensor to ensure that the die-cutting knife 72 is accurately aligned with the edge of the paper, avoiding paper waste and product quality problems caused by inaccurate alignment; dynamic tension control is implemented to ensure that the tension of the paper is stable during the die-cutting process, avoiding deformation or tearing of the paper due to tension fluctuations, affecting the die-cutting accuracy.

[0028] Furthermore, the traction mechanism 5 is located at the rear end of the correction mechanism 4, and the traction mechanism 5 cooperates with the unwinding mechanism 2 to realize horizontal transportation of paper. In this embodiment, a high-precision servo motor drive is adopted to ensure that the traction mechanism 5 can provide accurate traction force according to the real-time needs of the paper, avoid relaxation or excessive stretching of the paper during transportation, and ensure the flatness and stability of the paper.

[0029] At the same time, it is equipped with an intelligent tension control system, which monitors the tension changes of the paper in real time through sensors and automatically adjusts the traction force to ensure uniform tension of the paper during transportation, avoiding deformation or tearing of the paper due to tension fluctuations, which affects the quality of subsequent processing.

[0030] In addition, the traction roller adopts low-friction material and optimized mechanical design to reduce the friction between the traction mechanism 5 and the paper, reduce the wear of the paper during the transportation process, and improve the service life and processing quality of the paper.

[0031] Reference Figure 2 and Figure 3 On the other hand, the forming mechanism 6 is provided with several groups, and the several groups of forming mechanisms 6 are arranged in the horizontal direction. The forming mechanism 6 includes a connecting frame 61, an outer sleeve 62, an inner sleeve 63 and a hot pressing forming assembly 64. Among them, the connecting frame 61 is used to carry the outer sleeve 62, the inner sleeve 63 is located inside the outer sleeve 62, and is used to cooperate with the outer sleeve 62 to guide and form the paper, and the hot pressing forming assembly 64 is installed in the middle of the outer sleeve 62 and the inner sleeve 63. The hot pressing forming assembly 64 is used to horizontally convey the paper and press the overlapping edges of the paper.

[0032] Specifically, the connecting frame 61 is formed by splicing a number of bearings. In the present embodiment, there are four bearings arranged in a matrix, and the outer edges of the bearings are formed. Therefore, the four bearings are spliced ​​together to form a bearing groove 611. The bearing groove 611 is cylindrical. The outer sleeve 62 is plugged into the bearing groove 611, and the outer wall of the outer sleeve 62 abuts against the inner wall of the bearing groove 611 to fix the outer sleeve 62.

[0033] Therefore, the structural design of the connecting frame 61 further enhances the stability and accuracy of the straw forming module. Specifically, the connecting frame 61 is formed by splicing four bearings, which are arranged in a matrix and have their outer edges specially molded so that the four bearings can fit tightly together to form a cylindrical bearing groove 611.

[0034] At the same time, the outer sleeve 62 and the bearing groove 611 are plug-fitted, that is, the outer wall of the outer sleeve 62 abuts against the groove wall of the bearing groove 611, ensuring that the outer sleeve 62 is firmly fixed during operation and reducing the displacement caused by vibration or external force, thereby ensuring the accuracy and consistency of the straw forming process.

[0035] In addition, the matrix arrangement of the bearings and the cylindrical design of the bearing groove 611 can also effectively disperse the pressure on the outer sleeve 62 during operation, thereby extending the service life of the entire straw forming module and further improving production efficiency and product quality.

[0036] Furthermore, a transverse tube 612 is provided on the bearing, and the transverse tube 612 is used to be connected to an external device to realize the installation of the straw forming module. Four transverse tubes 612 are provided, and the four transverse tubes 612 are respectively and sequentially fixed vertically to the four bearings.

[0037] Therefore, the transverse tube 612 is arranged perpendicularly to the bearing to form a stable support frame. The transverse tube 612 is not only used to connect with external equipment to achieve rapid installation and removal of the straw forming module, but also can withstand the force transmitted by the external equipment to ensure the stability and reliability of the entire straw module during operation.

[0038] In addition, the design of the transverse tube 612 also takes into account the optimization of the spatial layout. The four transverse tubes 612 are respectively connected to four bearings 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.

[0039] On the other hand, the outer sleeve 62 is sleeved on the outer side of the inner sleeve 63, and a forming groove 621 is formed between the inner wall of the outer sleeve 62 and the inner wall of the inner sleeve 63. The hot pressing forming assembly 64 includes a driving motor 641, a hot pressing roller 642 and a driven roller 643. The driving motor 641 is installed on the outer side of the outer sleeve 62 and fixed to one of the bearings. The hot pressing roller 642 is coaxially fixed to the output shaft of the driving motor 641. The driven roller 643 is rotatably carried on the inner wall of the inner sleeve 63. The hot pressing roller 642 and the driven roller 643 are parallel to each other. At the same time, both the outer sleeve 62 and the inner sleeve 63 are provided with a clearance port 622, and the clearance port 622 is connected with the forming groove 621. The clearance port 622 is for the hot pressing roller 642 and the driven roller 643 to make way, and the gap formed between the hot pressing roller 642 and the driven roller 643 is located in the forming groove 621.

[0040] Correspondingly, after the paper is inserted from one end of the forming groove 621, the forming groove 621 shapes the paper. When the paper passes through the hot pressure roller 642 and the driven roller 643, the corresponding control driving motor 641 is started, and the hot pressure roller 642 rotates under the drive of the motor, and cooperates with the driven roller 643 to apply heat and pressure to the paper material in the forming groove 621, and at the same time provide power for conveying the paper.

[0041] Therefore, the outer sleeve 62 is sleeved on the outside of the inner sleeve 63, and the forming groove 621 formed between the two is the key area for straw forming. The hot pressing forming assembly 64 includes a driving motor 641, a hot pressing roller 642 and a driven roller 643, wherein the driving motor 641 is installed on the outside of the outer sleeve 62 and fixed to one of the bearings, ensuring the stability and accuracy of the motor operation.

[0042] At the same time, the hot pressing roller 642 is coaxially fixed to the output shaft of the driving motor 641, and the driven roller 643 is rotatably supported on the inner wall of the inner sleeve 63. The two are parallel to each other and act together on the paper material in the forming groove 621 to form the straw through hot pressing.

[0043] In addition, the outer sleeve 62 and the inner sleeve 63 are provided with clearance openings 622, which are interconnected with the molding groove 621, providing necessary space for the movement of the hot pressing roller 642 and the driven roller 643, ensuring that the gap formed between the hot pressing roller 642 and the driven roller 643 can be accurately positioned in the molding groove 621, thereby ensuring the dimensional accuracy and surface quality during the straw molding process. At the same time, the design of the clearance openings 622 can also effectively reduce the mutual interference between the hot pressing roller 642 and the driven roller 643 during the working process, thereby improving the operating efficiency and reliability of the entire molding module.

[0044] In this embodiment, the driving motor 641 is a servo motor, and the surface of the hot pressing roller 642 is provided with a heating layer, and the heating layer adopts an electric heating wire heating method. The servo motor has the characteristics of high precision, fast response speed and good control performance, and can accurately control the rotation speed and position of the hot pressing roller 642 to ensure the stability and precision of the straw forming process. At the same time, the surface of the hot pressing roller 642 is provided with a heating layer, and the heating layer adopts an electric heating wire heating method. The heat generated by the electric heating wire evenly heats the surface of the hot pressing roller 642, 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 molding and the quality of straw products.

[0045] Furthermore, one end of the outer sleeve 62 and the inner sleeve 63 are expanded outward, and the expanded end of the outer sleeve 62 and the inner sleeve 63 is the feeding end of the paper. The expanded end provides a wider entrance for the paper, reduces the resistance of the paper when entering the forming module, reduces the wrinkles or deviations of the paper during the introduction process, and ensures the smooth straw forming process and the precise positioning of the paper.

[0046] In addition, a fixing block 623 is provided between the outer sleeve 62 and the inner sleeve 63. The fixing block 623 is located at one end where the outer sleeve 62 and the inner sleeve 63 are expanded. The fixing block 623 is fixed to the inner wall of the outer sleeve 62 and the outer wall of the inner sleeve 63 respectively.

[0047] Correspondingly, the inlet ends of the inner sleeve 63 and the outer sleeve 62 are both large-diameter. At this time, the two sides of the paper are not rolled up to overlap, so there is a vacant space here and it will not interfere with the paper. Then, the fixing block 623 is used to fix the inner sleeve 63 and the outer sleeve 62 together.

[0048] Replay Figure 1 On the other hand, the cutting mechanism 7 includes a driving cylinder 71, a cutter 72 and a supporting platform 73. The supporting platform 73 is located on one side of the forming groove 621. The supporting platform 73 is used to support the paper sent out from the forming groove 621. The driving cylinder 71 is located above the supporting platform 73. The cutter 72 is installed on the piston rod of the driving cylinder 71, and the cutter 72 moves in the vertical direction.

[0049] Correspondingly, in the cutting mechanism 7 of the high-speed single-slit water-based coated straw machine, when the paper is fed out of the forming groove 621 and stably placed on the supporting platform 73, the piston rod of the driving cylinder 71 moves downward rapidly under the push of the air pressure, driving the cutter 72 to move down precisely in the vertical direction, contacting the paper on the supporting platform 73 and cutting. After the cutting is completed, the piston rod of the driving cylinder 71 retracts under the action of the air pressure, driving the cutter 72 to rise, completing one cutting action and preparing for the next cutting cycle.

[0050] Therefore, the cutting mechanism 7 realizes the rapid downward pressure and stable retraction of the cutter 72 through the precise control of the driving cylinder 71, ensuring the efficiency and precision of the cutting process. The sharp edge of the cutter 72 and the vertical cutting movement ensure the smoothness of the cut edge of the paper and avoid the generation of burrs and tears. The supporting role of the support platform 73 ensures the stability of the paper during the cutting process and avoids cutting errors caused by paper shaking. The entire cutting process is efficient and accurate, which significantly improves production efficiency and reduces production costs, providing a high-quality cutting solution for the straw manufacturing industry.

[0051] Furthermore, a plurality of positioning grooves 731 are horizontally provided on the upper surface of the support platform 73, and the shape of the positioning grooves 731 matches the shape of the straw. A plurality of clearance grooves 732 are also provided on the support platform 73, and the clearance grooves 732 are connected to the positioning grooves 731, and the positions of the clearance grooves 732 correspond to the positions of the cutters 72.

[0052] Therefore, the upper surface of the carrier 73 is designed with a positioning groove 731 that matches the shape of the straw, ensuring the accurate alignment of the paper during the cutting process and avoiding cutting deviation. At the same time, the clearance groove 732 opened on the carrier 73 is connected to the positioning groove 731, and the position corresponds to the cutter 72. This design allows the cutter 72 to pass smoothly when pressing down for cutting, avoiding direct contact between the cutter 72 and the carrier 73, reducing equipment wear, ensuring the stability and cutting quality of the cutting process, and at the same time improving the service life and production efficiency of the equipment.

[0053] In this embodiment, the number of the forming mechanisms 6 and the number of the positioning slots 731 can be adjusted to meet different production requirements.

[0054] On the other hand, the high-speed single-seam water-based coated straw machine in the present application also includes a control system for controlling the coordinated work of the unwinding mechanism 2, the longitudinal die-cutting mechanism 3, the correcting mechanism 4, the traction mechanism 5, the forming mechanism 6 and the cutting mechanism 7.

[0055] Specifically, the control principle of the control system in the high-speed single-slit water-based coated straw machine is based on the closed-loop control theory. The key parameters of the production process, such as paper tension, position, speed, and cutting accuracy, are collected in real time through sensors, and these data are fed back to the control center. The control center analyzes and processes the collected data through preset control algorithms, such as PID (proportional-integral-differential) control, compares it with the preset target value, and calculates the deviation of the control quantity. According to the size and direction of the deviation, the control system will automatically adjust the operating parameters of each mechanism, such as motor speed, cylinder pressure, cutter 72 position, etc., to achieve the purpose of precise control. This closed-loop control mechanism ensures the stability of the production process and the consistency of product quality. At the same time, through real-time monitoring and adjustment, the control system can quickly respond to changes in the production process, such as slight fluctuations in paper thickness or slight wear of equipment, thereby achieving precise synchronization and efficient coordination of processes such as unwinding, die-cutting, deviation correction, traction, forming and cutting, ensuring the high efficiency and high precision operation of the straw machine.

[0056] The implementation principle of the high-speed single-slit water-based coating straw machine in the embodiment of the present application is: The straw forming module is composed of an outer sleeve 62, an inner sleeve 63 and a hot pressing forming component 64, wherein the outer sleeve 62 is sleeved on the outside of the inner sleeve 63, and a forming groove 621 is formed between the two. During operation, several small rolls of paper are guided into the forming groove 621. With the continuous transportation of the paper, the paper is wound into a cylindrical structure in the forming groove 621 to form the initial shape of the straw. During the paper winding process, the overlapping edges of the paper will pass through the hot pressing forming component 64, which presses the edges of the paper together by heating and pressurizing to achieve the bonding of the paper, thereby ensuring the structural stability and sealing of the straw. The whole process has a high degree of automation and can continuously and efficiently produce high-quality straws to meet the market's high requirements for production efficiency and product quality.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
