[0014] By adopting the above solution, the roller is separated from the main frame and is set on a mobile frame. The mobile frame is moved in and removed through the installation port and positioned by a positioning mechanism, that is, the roller is integrated on the mobile frame. When a roller with a different type of mold cavity is needed, the positioning is canceled and the roller is moved out through the mobile frame, and then the mobile frame with the roller of another type is pushed in and positioned. Compared with the traditional switching method, the switching efficiency is high and the professional level of the operator is low. Therefore, it can effectively reduce the production cost and improve the production efficiency. Compared with lifting the roller out by a forklift, it can effectively improve the safety of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is described below with reference to the accompanying drawings and specific embodiments. Example 1

[0020] A roller quick-change water-soluble film packaging machine includes a main frame 1, a mobile frame 2 and a roller 3 arranged on the mobile frame 2. A mounting port 4 for moving the mobile frame 2 in or out is provided on one side of the main frame 1, and a positioning mechanism is provided between the mobile frame 2 and the main frame 1.

[0021] The positioning mechanism includes a number of upwardly arranged positioning pins 5 on the main frame 1 and a number of downwardly arranged positioning holes 6 on the mobile frame 2. The positioning pins 5 are in the shape of a truncated cone, and the positioning holes 6 are conical holes that match the shape of the positioning pins 5. The positioning pins 5 support the mobile frame 2 through the positioning holes 6. The positioning pins 5 are arranged in the shape of a truncated cone, which can automatically correct the deviation and find the alignment, and quickly and accurately position. A lifting mechanism is provided at the bottom of the mobile frame 2 for driving the mobile frame 2 to move longitudinally relative to the main frame 1. The mobile frame 2 moves longitudinally relative to the main frame 1 so that the positioning pins 5 and the positioning holes 6 are close to each other for positioning or move away from each other to lose positioning.

[0022] Specifically, a plurality of caster units are provided at the bottom of the mobile frame 2. The caster units include a lifting mechanism and a caster 7 provided at the bottom of the lifting mechanism. The mobile frame 2 is moved in or out from the installation port 4 through the caster 7. The lifting mechanism is a cylinder 8. The caster 7 is installed on the mobile frame 2 through the cylinder 8. When the cylinder 8 drives the mobile frame 2 to the upper limit position, the position of the positioning hole 6 is higher than the positioning pin 5. After the cylinder 8 controls the mobile frame 2 to descend, the positioning pin 5 extends into the positioning hole 6.

[0023] With the above solution, the roller 3 is separated from the main frame 1, but is separately set on the mobile frame 2. The mobile frame 2 moves in and out through the installation port 4 and is positioned by the positioning mechanism. Specifically, when the roller 3 needs to be replaced, the cylinder 8 lifts the mobile frame 2, the positioning pin 5 is removed from the positioning hole 6, and the mobile frame 2 is manually pushed out to complete the removal of the old roller 3. The roller 3 to be installed is pushed in from the installation port 4 along with the mobile frame 2, the positioning hole 6 is moved to the top of the positioning pin 5, the cylinder 8 returns, the positioning hole 6 moves downward and the positioning pin 5 is inserted, achieving precise positioning and completing the switching of the roller 3. Compared with the traditional switching method, the switching efficiency is high and the professional level of the operator is low. Therefore, it can effectively reduce the cost of production and improve the efficiency of production. Compared with lifting the roller out by a forklift, it can effectively improve the safety of the operation. Example 2

[0024] like Figure 2 、 3 As shown, the mobile frame 2 can also integrate a conveying mechanism 9, a filling mechanism 10 and a cross-cutting knife mechanism 11. The conveying mechanism 9 is a conveyor belt arranged at the bottom of the drum 3. The cross-cutting knife mechanism 11 includes a cross-cutting knife, and the cutting edge of the cross-cutting knife faces the drum 3.

[0025] The filling mechanism 10 includes a filling nozzle mounting plate 12 arranged above the drum 3 and a plurality of filling nozzles 13 arranged on the filling nozzle mounting plate 12. A plurality of mold cavity groups are distributed circumferentially on the drum 3. The mold cavity group includes a plurality of mold cavities 14 arranged along the axial direction. The plurality of filling nozzles 13 are arranged in sequence along the axial direction of the drum 3.

[0026] In addition, if Figure 4 As shown, the filling mechanism 10 also includes a motor 15, an eccentric wheel 16, a connecting arm 17, and a swing arm 18. The output shaft of the motor 15 is connected to one end of the connecting arm 17 via the eccentric wheel 16. The other end of the connecting arm 17 is connected to the swing arm 18. The lower end of the swing arm 18 is rotatably mounted on the movable frame 2 and rotates coaxially with the drum 3. The upper end of the swing arm 18 is connected to the filling nozzle mounting plate 12. During filling, the filling nozzle 13 can swing synchronously with the mold cavity 14 on the drum 3, improving filling accuracy and preventing material from spilling outside the mold cavity 14.

[0027] With this preferred solution, the roller 3, the filling mechanism 10, the conveying mechanism 9 and the cross-cutting knife mechanism 11 are all integrated on the mobile frame 2. The filling mechanism 10, the conveying mechanism 9 and the cross-cutting knife mechanism 11 are paired with a special roller 3, which can further reduce the switching debugging time when the roller 3 is switched. In addition, the roller 3 can also be quickly taken out for easy maintenance.

[0028] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications, combinations, and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims.
