Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, specifically to a spiral winding forming mold for paper tube packaging boxes. Background Technology

[0002] In the manufacturing of paper tube packaging boxes, spiral winding forming technology is one of the key processes for forming paper tube structures. With the continuous development of the packaging industry, the demand for paper tube packaging boxes is increasing, and the requirements for their quality, precision, and production efficiency are also becoming more stringent. As the core component of this process, the performance and design of the spiral winding forming mold for paper tube packaging boxes directly affect the forming quality, production speed, and production flexibility. Therefore, in-depth research and development of spiral winding forming mold technology for paper tube packaging boxes is of great significance for improving the production level of paper tube packaging boxes.

[0003] Currently, the traditional spiral winding forming of paper tube packaging boxes suffers from complex mold installation structures and time-consuming, cumbersome operations when changing mold sleeves, severely impacting production flexibility and efficiency. Furthermore, poor control of friction between the mold and the paper tube material leads to slippage, resulting in uneven winding and affecting product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a spiral winding forming mold for paper tube packaging boxes, so as to solve the problems mentioned in the background art, which are that the existing spiral winding forming installation structure of paper tube packaging boxes is relatively complicated and the operation is cumbersome when changing the mold sleeve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A spiral winding forming mold for paper tube packaging boxes includes a winding shaft for spiral winding of paper tube packaging boxes and a winding forming mold sleeve sleeved on the winding shaft. Locking bolts are embedded on the outer wall of the winding forming mold sleeve, and one end of the winding shaft is connected to a servo reduction motor. The winding molding die sleeve includes an inner core, the surface of which is provided with a reinforcing outer shell, the surface of which is provided with an anti-slip sleeve, and a connecting socket that is adapted to the cross-sectional dimensions of the winding shaft and is interference-fitted at the center of the inner core.

[0006] Preferably, both the winding shaft and the connecting socket have square cross-sections, as this shape allows for better torque transmission. During the spiral winding of the paper tube packaging box, a stable power transmission is required between the mold sleeve and the winding shaft. The square cross-section prevents relative rotation during the winding process, ensuring synchronization and stability, thereby improving the quality and precision of the paper tube forming.

[0007] Preferably, the anti-slip sleeve is made of rubber with a thickness of 1-4mm, which can ensure the anti-slip effect without excessively increasing the size and weight of the mold sleeve, thus benefiting the overall operation of the equipment and cost control.

[0008] Preferably, the outer wall of the winding shaft has threaded holes that are adapted to the size and position of the locking bolts and are threadedly connected, so that the locking bolts can be accurately screwed into the threaded holes. This ensures that the winding forming mold is securely locked onto the winding shaft, and during operation, it ensures that the mold sleeve will not loosen due to vibration or external force, thus guaranteeing the stability and safety of the winding process and improving production efficiency.

[0009] Preferably, the output end of the servo geared motor is equipped with a rotating shaft, providing a basic structure for power transmission. As a key component for power transmission, the rotating shaft can stably output the power generated by the servo geared motor, facilitating connection and power transmission with other components. This is an important design feature for realizing the power source for the spiral winding of the paper tube.

[0010] Preferably, the end of the winding shaft is coaxially connected to a plug-in post that engages with the rotating shaft, enabling convenient connection and power transmission between the servo geared motor and the winding shaft. This plug-in engagement method makes the installation and disassembly of the equipment more convenient and quick, saving time and labor costs when parts need to be replaced or repaired, and improving the maintainability of the equipment.

[0011] Preferably, the servo geared motor is equipped with a vibration-damping base at its bottom, which can effectively reduce the vibration generated during the operation of the servo geared motor. During operation, the motor will generate a certain amount of vibration. If this vibration is directly transmitted to other parts of the equipment, it will affect the stability and accuracy of the equipment, and may even cause damage. The vibration-damping base can absorb and buffer vibrations, improve the overall stability of the equipment, and extend its service life.

[0012] Preferably, the bottom edge of the shock-absorbing base is fitted with a ring-shaped fixing seat, which facilitates the secure fixing of the servo geared motor in the working position. During operation, the equipment needs to maintain a stable position. The fixing seat can be connected to the work platform or other fixed devices to prevent the equipment from moving or shaking, ensuring the smooth progress of the paper tube spiral winding process and improving the stability and reliability of production.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: In this spiral winding forming mold for paper tube packaging boxes, the winding shaft and the easily replaceable winding forming mold sleeve fitted on it allow for quick replacement of the mold sleeve according to the production needs of different paper tube packaging boxes, improving production flexibility; the locking bolts embedded on the outer wall of the winding forming mold sleeve can lock and fix the position of the mold sleeve on the winding shaft, ensuring the stability of the winding process; one end of the winding shaft is connected to a servo reduction motor, which can precisely control the rotational speed of the winding shaft. The rotation angle ensures the accuracy of the spiral winding of the paper tube packaging box; the winding forming mold sleeve includes an inner core, the surface of which is provided with a reinforcing shell, which can enhance the strength and durability of the mold sleeve and extend its service life; the surface of the reinforcing shell is provided with an anti-slip sleeve, which can increase the friction between the mold sleeve and the paper tube material and prevent slippage during the winding process; a connecting socket with an interference fit that is adapted to the cross-sectional size of the winding shaft is opened at the center of the inner core, which makes the connection between the mold sleeve and the winding shaft tight and easy to install and disassemble.

[0018] Paper tube packaging box spiral winding forming mold, such as Figures 1-3 As shown, the device includes a winding shaft 20 for spiral winding of paper tube packaging boxes and a winding forming mold sleeve 10 that is sleeved on the winding shaft 20 and is easily replaceable. A locking bolt 40 is embedded in the outer wall of the winding forming mold sleeve 10. One end of the winding shaft 20 is connected to a servo reduction motor 50. The winding forming mold sleeve 10 includes an inner core 11, a reinforcing outer shell 12 on the surface of the inner core 11, and an anti-slip sleeve 13 on the surface of the reinforcing outer shell 12. A connecting insertion hole 14, which is adapted to the cross-sectional dimensions of the winding shaft 20 and fits with an interference fit, is opened at the center of the inner core 11. Through the winding shaft 20 and the easily replaceable winding forming mold sleeve 10 sleeved on it, the mold sleeve can be quickly changed according to the production needs of different paper tube packaging boxes, improving production flexibility. The locking bolt 40 is embedded in the outer wall of the winding forming mold sleeve 10. The mold sleeve can be locked and fixed on the winding shaft to ensure the stability of the winding process. One end of the winding shaft 20 is connected to the servo geared motor 50, which can accurately control the speed and rotation angle of the winding shaft to ensure the accuracy of the spiral winding of the paper tube packaging box. The winding forming mold sleeve 10 includes an inner core 11, and the surface of the inner core 11 is provided with a reinforcing shell 12. The reinforcing shell 12 can enhance the strength and durability of the mold sleeve and extend its service life. The surface of the reinforcing shell 12 is provided with an anti-slip sleeve 13, which can increase the friction between the mold sleeve and the paper tube material and prevent slippage during the winding process. The connecting socket 14, which is adapted to the cross-sectional size of the winding shaft 20 and is interference-fitted, is opened at the center of the inner core 11, so that the mold sleeve and the winding shaft are tightly connected and easy to install and disassemble.

[0019] It is worth noting that the cross-sections of the winding shaft 20 and the connecting hole 14 are both square, which allows the winding forming mold sleeve 10 and the winding shaft 20 to better transmit torque, avoid relative rotation during rotation, and ensure the synchronization and stability of the winding process.

[0020] Among them, the anti-slip sleeve 13 is made of rubber and has a thickness of 1-4mm. The rubber material has good elasticity and friction properties, which can effectively increase the friction between the paper tube and the mold sleeve and prevent the paper tube from sliding during the winding process. At the same time, the appropriate thickness can ensure the anti-slip effect without increasing the size and weight of the mold sleeve too much.

[0021] Furthermore, the outer wall of the winding shaft 20 is provided with a screw hole 21 that is adapted to the size of the locking bolt 40, corresponds to the position, and is threadedly connected, so that the locking bolt 40 can be accurately screwed into the screw hole 21, thereby achieving a firm lock on the winding forming mold sleeve 10 on the winding shaft 20 and ensuring that the mold sleeve will not loosen during operation.

[0022] Specifically, the output end of the servo geared motor 50 is equipped with a rotating shaft 51, and the end of the winding shaft 20 is coaxially connected with a plug post 30 that engages with the rotating shaft 51, thus realizing convenient connection and power transmission between the servo geared motor 50 and the winding shaft 20, facilitating the installation and disassembly of the equipment.

[0023] In addition, a shock-absorbing base 52 is installed at the bottom of the servo geared motor 50, and a ring-shaped fixing seat 53 is installed on the bottom edge of the shock-absorbing base 52. The shock-absorbing base 52 can effectively reduce the vibration generated by the servo geared motor 50 during operation and improve the stability of the equipment. The fixing seat 53 makes it easy to firmly fix the servo geared motor 50 in the working position.

[0024] The working principle of this spiral winding forming mold for paper tube packaging boxes: First, according to the production requirements of paper tube packaging boxes, select a suitable winding forming mold sleeve 10 and insert it into the winding shaft 20 through the connecting socket 14 to ensure a tight connection; then, adjust the position of the mold sleeve and tighten the locking bolt 40 embedded on the outer wall of the winding forming mold sleeve 10 so that it is screwed into the screw hole 21 on the outer wall of the winding shaft 20, and firmly lock the mold sleeve onto the winding shaft 20. Then, the plug-in post 30 at the end of the winding shaft 20 is plugged into the rotating shaft 51 at the output end of the servo geared motor 50 to achieve power connection; the bottom of the servo geared motor 50 is installed in the working position through the shock-absorbing base 52 and is firmly fixed by the fixing ring seat 53. The servo reduction motor 50 is started, which precisely controls the speed and rotation angle of the winding shaft 20, driving the winding forming mold sleeve 10 to rotate; the anti-slip sleeve 13 on the surface of the winding forming mold sleeve 10 increases the friction with the paper tube material to prevent slippage, and performs spiral winding forming of the paper tube packaging box.

[0025] 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.
