[0028] The discharging adjustment assembly 2 includes two mounting plates 21 and a movable plate 25. The lower ends of the two mounting plates 21 are fixedly connected to the front and rear positions of the middle part of the upper end of the bottom plate 1. A heating box 22 is fixedly installed on the top of the opposite sides of the two mounting plates 21. The front and rear parts of the inner wall of the heating box 22 are movably connected with a stirring mechanism 23. The front and rear parts of the lower end of the heating box 22 are both trapezoidal structures. The front and rear parts of the lower end of the heating box 22 are both connected to a rectangular discharging pipe 24. The left and right sides of the movable plate 25 are fixedly connected to the movable mechanism 26. , the front and rear parts of the lower end of the movable plate 25 are rotatably connected to the symmetrically arranged adjustment plates 27, and the ends of the two adjustment plates 27 away from the movable plate 25 are rotatably connected to the blocking plates 28. The middle parts of the opposite sides of the two discharge pipes 24 are provided with movable grooves matching the two blocking plates 28. The bottoms of the opposite sides of the two mounting plates 21 are fixedly installed with a distribution frame 29 with an open top. The lower end of the distribution frame 29 is provided with a plurality of linearly arranged discharge ports 210, and the two discharge pipes 24 are located in the distribution frame 29;

[0029] The adjustment and adaptation component 3 includes an adjustable reverse double-threaded rod 31, the front and rear ends of the reverse double-threaded rod 31 are rotatably connected to the left position of the bottom of the opposite sides of the two mounting plates 21, and the left and right parts of the outer wall of the reverse double-threaded rod 31 are threadedly connected to the multi-port blocking plate 32, and the upper ends of the two multi-port blocking plates 32 overlap with the front and rear parts of the lower end of the material dividing frame 29.

[0030] By adjusting the discharge assembly 2, the amount of flowing film discharged from the heating box 22 can be precisely controlled. When the moving mechanism 26 controls the up and down movement of the movable plate 25, the two blocking plates 28 are subsequently extended or inserted into the two discharge tubes 24, thereby controlling the amount of film coating. The movement of the movable plate 25 is directly controlled by the electric push rod 261, which provides high precision and further improves the degree of automation of the structure. By adjusting the adaptive component 3, the number of discharge ports 210 can be adjusted according to the processing size of the paper cup paper sheet. By rotating the counter-rotating double-threaded rod 31, the two multi-port blocking plates 32 move in opposite directions. According to the processing requirements, the discharge ports 210 required for discharge are exposed, and the discharge ports 210 not required for discharge are blocked, thereby improving the adaptability of the structure.

[0031] like Figure 4 As shown, the stirring mechanism 23 includes two rotating shafts 231, and the top of the outer wall of the two rotating shafts 231 is rotatably connected to the inner wall of the front and rear parts of the upper end of the heating box 22.

The bottom of the outer wall of the two rotating shafts 231 is fixedly installed with a number of stirring rods 234 arranged in a linear manner.

[0032] When the motor 233 is started, the shaft 231 at the rear rotates, and the two shafts 231 rotate synchronously in opposite directions through the engagement of the two gears 232, so that the flowing film in the heating box 22 can be evenly mixed by the multiple stirring rods 234, which is also beneficial to heat transfer and improves processing efficiency.

[0033] like Figure 5 As shown, the moving mechanism 26 includes an electric push rod 261, the left side of the electric push rod 261 is fixedly connected to the right bottom of the heating box 22, and Z-shaped frames 262 are fixedly installed on the left and right sides of the moving plate 25. The output end of the electric push rod 261 is fixedly connected to the upper right part of the right Z-shaped frame 262.

[0034] When the electric push rod 261 is started, it will drive the movable plate 25 to move up and down through the right Z-shaped frame 262.

[0035] like Figure 5 As shown, a guide rod 263 is fixedly installed on the left bottom of the heating box 22, and the inner wall of the left part of the left Z-shaped frame 262 is slidably connected to the outer side of the guide rod 263.

[0036] The guide rod 263 limits and supports the movement of the movable plate 25 .

[0037] like Figure 4 and Figure 5 As shown, the size of the two blocking plates 28 is consistent with the size of the inner walls of the two discharge pipes 24 .

[0038] It helps to block and adjust the discharge volume of the two discharge pipes 24.

[0039] like Figure 4 and Figure 5 As shown, a limiting rod 33 is fixedly installed at the right position of the bottom of the opposite sides of the two mounting plates 21, and the left inner walls of the two multi-port blocking plates 32 are slidingly connected to the outer front and rear parts of the limiting rod 33. The left position of the bottom of the opposite sides of the two mounting plates 21 is provided with a through groove matching the two multi-port blocking plates 32.

[0040] The limiting rod 33 has a limiting and guiding effect on the movement of the two multi-port blocking plates 32 .

[0041] like Figure 3 and Figure 4 As shown, a feeding pipe is fixedly installed at the rear portion of the upper end of the heating box 22 , and heaters 13 are fixedly installed at the front and rear portions of the inner wall of the heating box 22 .

[0042] The heater 13 is an existing mechanism for heating the laminating material.

[0043] The working principle of the present invention is as follows: During use, the two blocking plates 28 are moved away from each other to completely block the two discharge pipes 24. An appropriate amount of coating material (such as plastic granules or molten plastic) is added to the heating box 22 through the feeding pipe. The two heaters 13 are activated, and the stirring mechanism 23 is activated to ensure that the coating material inside the heating box 22 is evenly mixed and heated. The unwinder 11 is used to place and release the paper cup sheets to be coated, and the rewinder 12 is used to collect the coated paper cup sheets. The two plates together stretch the paper cup sheets and position them directly below the material separation frame 29. According to the width of the paper cup sheets, the reverse double-threaded rod 31 is rotated, and the two multi-port blocking plates 32 are threadedly connected to the reverse double-threaded rod 31 to move in opposite directions. The two plates expose the discharge ports 210 required for discharge and block the discharge ports 210 that are not required for discharge according to processing requirements.

[0044] The electric push rod 261 starts automatically, and its output end can drive the right Z-shaped frame 262 to move upward. The two Z-shaped frames 262 and the movable plate 25 will move upward synchronously. According to the system settings, the movable plate 25 will move a specified distance. At this time, the two adjustment plates 27 rotate and simultaneously pull the two blocking plates 28 closer to each other, so that the two blocking plates 28 open the two discharge pipes 24 to the specified discharge space. The coating material in the heating box 22 falls evenly into the distribution frame 29 through the two discharge pipes 24, and the coating material in the distribution frame 29 falls on the surface of the paper cup paper through the exposed discharge port 210, thereby realizing the coating process.
