[0026] The uniform pressing assembly includes an electric push rod 4, which is fixedly connected to the support frame 3, and the output end of the electric push rod 4 is fixedly connected to a fixing frame 5, and the lower end of the fixing frame 5 is fixedly connected to a hexagonal sliding sleeve 6;

[0027] A hexagonal sliding shaft 7 is slidably connected inside the hexagonal sliding sleeve 6, and a convex fixing plate 9 is fixedly connected to the lower end of the hexagonal sliding shaft 7. A plurality of clamping components are arranged on the convex fixing plate 9. The clamping components are used to stretch the inner wall of one end of the main body of the pencil case outward, and the plurality of clamping components are evenly arranged in a circular array.

[0028] Furthermore, the clamping assembly includes a small shaft 10, which is rotatably connected to the convex fixed disk 9. Both ends of the small shaft 10 rotate through the outer surface of the convex fixed disk 9. The lower end of the small shaft 10 is fixedly sleeved with a rotating clamping block 11, which is used to clamp the inner wall of one end of the main body of the pencil case.

[0029] Furthermore, a sector block 12 is fixedly sleeved on the upper end of the small shaft 10 , an outer surface of the sector block 12 is provided with an inclined groove 13 , and an outer surface of the hexagonal sleeve 6 is fixedly connected with an arc plate 14 .

The heating ring 2 is prior art and will not be described in detail here.

[0033] Furthermore, when in use, the end cover of the pencil case to be heat-sealed is placed with the opening facing upward in the heating ring 2, and then one end of the main body of the pencil case is placed in the opening of the end cover of the pencil case, and then the electric push rod 4 is started. The electric push rod 4 can drive the mechanism thereon to move downward until the lower end of the convex fixing plate 9 contacts the bottom wall of the end cover of the pencil case. At this time, the convex fixing plate 9 will drive the hexagonal sliding shaft 7 to move upward. At this time, the tension spring 19 is stretched and deformed. When the convex fixing plate 9 moves, it drives the fan-shaped block 12 thereon to move upward at the same time, so that the fan-shaped block 12 can be subjected to the interaction force between the inclined groove 13 and the fixed sliding column 15, so that the fan-shaped block 12 can rotate.

[0034] Furthermore, the uniform pressing component can quickly and accurately heat-press the pen case and its end caps together. This semi-automatic operation method can quickly and accurately complete the heat-sealing process of the pen case and the end caps, significantly improving production efficiency. Compared with the traditional manual heat-sealing method, the heat-sealing machine not only saves manpower, but also greatly improves the speed and accuracy of heat-sealing.

[0035] Furthermore, by setting up multiple pressing components to press the circular pencil case, it has high adaptability. No matter the pencil case is made of plastic, cloth or other materials, the heat sealing machine can perform fast and accurate heat sealing to meet different production needs, reduce the scrap rate caused by poor heat sealing, and reduce production costs. At the same time, the use of the heat sealing machine also reduces the dependence on skilled workers and reduces labor costs.

[0036] Working principle: when in use, place the end cover of the pencil case that needs to be heat-sealed with its opening facing upwards in the heating ring 2, and then put one end of the main body of the pencil case into the opening of the end cover of the pencil case, and then start the electric push rod 4, which can drive the mechanism on it to move downward until the lower end of the convex fixed disk 9 contacts the bottom wall of the end cover of the pencil case. At this time, the convex fixed disk 9 will drive the hexagonal sliding shaft 7 to move upward. At this time, the tension spring 19 is stretched and deformed. When the convex fixed disk 9 moves, it drives the fan-shaped block 12 on it to move upward at the same time, so that the fan-shaped block 12 can be subjected to the interaction force between the inclined groove 13 and the fixed sliding column 15, so that the fan-shaped block 12 can rotate. At this time, the rotating fan-shaped block 12 can drive the rotating pressing block 11 to rotate through the small shaft 10, and the rotating rotating pressing block 1 1 can be rotated out until the rotating pressing block 11 contacts one end of the main body of the pencil case, and one end of the main body of the pencil case is supported in the opening of the end cover of the pencil case, and then the heating ring 2 is started. Under the continuous heating of the inner wall of the heating ring 2, the rotating pressing block 11 will press the pencil case and the end cover of the pencil case together, and then the electric push rod 4 is controlled to shrink, so that the convex fixing plate 9 moves upward, and the rotating pressing block 11 at this time will rotate back to the original position, and at this time, the motor 17 is controlled to start rotating, and the motor 17 drives the gear sleeve 16 to rotate a certain angle through the motor gear 18 thereon, so that the pressing component at its lower end can follow the rotation of a certain angle, so that the pressing component can press the unpressed area, so that the end cover of the pencil case and the main body of the pencil case can be pressed together evenly.
