[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-3 This is a structural schematic diagram of the longitudinal sealing and heating mechanism and its specific components in this utility model. As shown in the figure, the longitudinal sealing and heating mechanism of this utility model includes a power shaft 9, a transmission assembly 13, a mounting base 1, a fixed base 2, a fixed wheel seat 3, a sliding wheel seat 4, a sliding shaft 6, and a fixing plate 5. The mounting base 1 is locked in the mounting hole of the fixed base 2. The tail end of the sliding shaft 6 passes through the sliding wheel seat 4 and the fixed wheel seat 5 respectively, and is integrally connected to the mounting base 1 with the fixed wheel seat 3. The sliding wheel seat 4 is sleeved on the sliding shaft 6, and a fixing sealing plate is installed on the fixed wheel seat 3. A sliding sealing wheel 8 is installed on the wheel 7 and the sliding wheel seat 4. A heater 16 is installed inside the fixed sealing wheel 7 and the sliding sealing wheel 8. A compression spring 15 is sleeved on the sliding shaft 6 and fixed to the front end of the sliding shaft 6 by the fixing plate 5 to press against the compression spring 15 so as to provide sealing pressure through the compression spring 15. The power shaft 9 passes through the mounting seat 1 and is connected to the transmission assembly 13. The power shaft 9 provides power output and drives the fixed wheel seat 3 and the sliding wheel seat 4 to move synchronously through the transmission assembly 13, thereby sealing the packaging between the fixed sealing wheel 5 and the sliding sealing wheel 6.

[0022] This structural design allows for simultaneous longitudinal sealing and heating, improving sealing efficiency and effectiveness.

[0023] In one possible implementation, an adjusting nut 14 is screwed to the front end of the sliding shaft 6 to adjust the compression amount of the compression spring 15.

[0024] By adjusting the nut, the compression amount of the compression spring can be adjusted, thereby adjusting the sealing pressure applied by the compression spring. In existing sealing mechanisms, the closing pressure between the sealing wheels cannot be adjusted, and the closing pressure between the sealing wheels cannot be adjusted according to the requirements of packaging materials and machine efficiency, which affects the performance of the machine. However, the sealing mechanism in this solution can adjust the closing pressure between the longitudinal sealing wheels to adapt to the different sealing pressure requirements of different packaging materials and ensure the sealing effect.

[0025] In one possible implementation, a buffer pad 12 is provided between the sliding wheel seat 4 and the fixed wheel seat 3.

[0026] In existing packaging machines, there is no buffer during the closing process between the sealing wheels. When closing, the sealing wheels make hard contact with each other, which increases the damage between the sealing wheels and the wear of the support bearings. However, the sealing mechanism of this utility model sets a buffer pad between the sliding wheel seat and the fixed wheel seat, which can play a good buffering role when the longitudinal sealing wheel closes, preventing the longitudinal sealing wheel from making hard contact impact.

[0027] In one possible implementation, the transmission assembly 13 includes a small bevel gear 131, a large bevel gear 132, a driving gear 133, and a driven gear 134. The small bevel gear 131 is mounted on the output end of the power shaft 9, and the large bevel gear 132 is mounted on the fixed wheel seat 3. The small bevel gear 131 and the large bevel gear 132 mesh to form a gear pair. The driving gear 133 is mounted on the fixed wheel seat 3, and the driven gear 134 is mounted on the sliding wheel seat 4. The driving gear 133 and the driven gear 134 mesh to form a gear pair.

[0028] The power shaft outputs power from the power source and transmits it to the large bevel gear through the small bevel gear to drive the fixed wheel seat to rotate. Furthermore, the rotation of the fixed wheel seat is linked to the driven gear through the driving gear to achieve a synchronous linkage effect, ensuring that the fixed wheel seat and the sliding wheel seat move synchronously and guarantee synchronous sealing.

[0029] In one possible implementation, an opening / closing seat 10 is provided on the outer side of the fixed plate 5 to pull or restrict the sliding of the sliding wheel seat 4.

[0030] In one possible implementation, the opening and closing seat 10 is also provided with an opening and closing handle 11, so as to control the opening and closing of the opening and closing seat 10 through the opening and closing handle 11.

[0031] The opening and closing handle is locked on the opening and closing seat. By pulling the opening and closing handle, the sliding wheel seat 4 is pulled and limited to slide.

[0032] In one possible implementation, the fixing seat 2 is a clamping structure to lock the mounting seat 1 by clamping.

[0033] The fixing seat has an upper and lower clamping structure. Specifically, an opening is made on one side of the fixing seat mounting hole, and the size of the opening is adjusted by a screw to achieve the effect of tightening or loosening the packaging material. Based on this structure, it can also be swung at a certain angle to achieve the purpose of tightening the packaging material.

[0034] The above detailed description of the longitudinal sealing and heating mechanism, in conjunction with the accompanying drawings, indicates that the mechanism comprises a power shaft, a transmission assembly, a mounting base, a fixed base, a fixed wheel seat, a sliding wheel seat, a sliding shaft, and a fixing plate. The mounting base is locked within the mounting hole of the fixed base. The tail end of the sliding shaft passes through both the sliding wheel seat and the fixed wheel seat, and is integrally connected to the mounting base. The sliding wheel seat is sleeved on the sliding shaft. A fixed sealing wheel is mounted on the fixed wheel seat, and a sliding sealing wheel is mounted on the sliding wheel seat. A heater is installed inside both the fixed and sliding sealing wheels. A compression spring is sleeved on the sliding shaft and fixed to the front end of the sliding shaft by the fixing plate to press against the spring, providing sealing pressure. The power shaft provides power output and drives the fixed wheel seat and the sliding wheel seat to move synchronously through the transmission assembly, thereby sealing the packaging bag between the fixed and sliding sealing wheels. This structural design achieves simultaneous longitudinal sealing heating and sealing, improving sealing efficiency and effectiveness.

[0035] In addition, by screwing an adjusting nut to the front end of the sliding shaft, the compression amount of the compression spring can be adjusted, thereby adjusting the sealing pressure of the compression spring on the sliding wheel seat to adapt to the different pressing pressure requirements of different packaging materials and ensure the sealing effect.

[0036] Furthermore, a buffer pad is installed between the sliding wheel seat and the fixed wheel seat, which can play a good buffering role when the longitudinal sealing wheel closes, preventing the longitudinal sealing wheel from making hard contact impact.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
