[0022] The support and protection assembly 6 includes a support cylinder 601, a support rod 602, and a protective spring 603. The support rod 602 is slidably connected inside the support cylinder 601, and the top of the support rod 602 is fixedly connected to the bottom of the support plate 1. The protective spring 603 is fixedly connected inside the support cylinder 601 and is located below the support rod 602.

[0023] The first adjusting assembly 8 includes a lead screw 801, a platform 802, a lifting rod 803, a threaded sleeve 804, a movable sleeve 805, a locking rod 806, a slotted hole 807, and a second motor 808. The lead screw 801 is rotatably connected between two rotating supports 7. The platform 802 is sleeved on the outside of the lead screw 801 and the guide rod 9. The lifting rod 803 is slidably connected inside the support plate 1. The threaded sleeve 804 is threadedly connected to the outside of the lead screw 801. The movable sleeve 805 is slidably connected to the outside of the threaded sleeve 804. The locking rod 806 is rotatably connected to one side of the movable sleeve 805. The slotted hole 807 is opened on one side of the platform 802. The second motor 808 is fixedly connected to one side of one of the rotating supports 7. The output end of the second motor 808 is fixedly connected to one end of the lead screw 801.

[0024] The second adjustment component 10 includes a bearing seat 1001, a gear 1002, two locking holes 1003, two insert rods 1004, and a rack lifting component 1005. The bearing seat 1001 is fixedly connected to the bottom of the support plate 1 and is sleeved on the outside of the lead screw 801. The gear 1002 is connected to one side of the bearing seat 1001. The two locking holes 1003 are symmetrically opened on one side of the gear 1002. The two insert rods 1004 are symmetrically fixedly connected to the side of the movable sleeve plate 805 near the locking holes 1003. The rack lifting component 1005 is fixed to the ground, and the top of the rack plate of the rack lifting component 1005 is fixedly connected to the bottom of the support plate 1.

[0025] The threaded sleeve 804 has a groove 12 on its outside. The movable sleeve 805 is fixedly connected to a slider 13 on its inside. The slider 13 is slidably connected inside the threaded sleeve 804. The bottom of the lifting rod 803 is rotatably connected to a roller 14. The roller 14 is in contact with the top of the platform 802. The inside of the waist-shaped hole 807 is fixedly connected to a magnet 15.

[0026] In the production of corn starch-based biodegradable composite lunch box extrusion sheets, the movable sleeve plate 805 can be moved first to insert the insertion rod 1004 into the card hole 1003. The second motor 808 is then started, which drives the lead screw 801 to rotate. At the same time, the threaded sleeve 804 and the movable sleeve plate 805 rotate, thereby causing the gear 1002 to rotate. Since the position of the gear 1002 does not change, it will block the threaded sleeve 804, preventing it from moving. This allows the threaded sleeve 804 to rotate but not move. At this time, the teeth of the gear 1002 mesh with the teeth of the rack plate of the rack lifting component 1005, causing the rack plate inside the rack lifting component 1005 to move upward, thereby raising the support plate 1 and simultaneously raising the material cylinder 2 to adjust its height. After the height adjustment is completed, the self-locking component on the rack lifting component 1005 prevents the rack plate inside the rack lifting component 1005 from moving. After the height adjustment, the movable sleeve 805 is reversed and moved to the position closest to the ladder platform 802. Then, the locking rod 806 is rotated and locked into the oblong hole 807. Subsequently, the second motor 808 is started, causing the output end of the second motor 808 to rotate in the opposite direction. The ladder platform 802 cannot rotate due to the setting of the guide rod 9, and the threaded sleeve 804 cannot rotate. As the screw 801 and the threaded sleeve 804 are threaded together, the locking rod 806 pushes the ladder platform 802 to move. The top slope of the ladder platform 802 slowly lifts the lifting rod 803, thereby lifting one side of the bottom of the material cylinder 2, achieving the purpose of changing the angle of the material cylinder 2. By adjusting, it can better adapt to the height of the machine in the downstream production line. After adjustment, the raw material is added into the inside of the material cylinder 2 from the feed hopper 5. The first motor 4 is started, and the output end of the first motor 4 drives the discharge rod 3 to rotate. At the same time, the material cylinder 2 heats the material inside. Through the cooperation of the discharge rod 3 and the material cylinder 2, the material is squeezed to the rear end. The protective spring 603 can provide elastic support for the support rod 602 to prevent the support plate 1 from falling suddenly and causing damage to the components on it. The roller 14 can reduce the friction between the lifting rod 803 and the platform 802.

[0027] Safety component 11 includes a water pump 1101, a water inlet pipe 1102, a spiral cooling pipe 1103, and a temperature sensor 1104. The water pump 1101 is fixedly connected to the top of the support and protection component 6. The water inlet pipe 1102 is fixedly connected to the input end of the water pump 1101. The spiral cooling pipe 1103 is evenly arranged in the cavity of the material cylinder 2, and one end of the spiral cooling pipe 1103 is fixedly connected to the output end of the water pump 1101. The other end of the spiral cooling pipe 1103 extends to the outside of the material cylinder 2. The temperature sensor 1104 is fixedly connected in the cavity of the material cylinder 2 and is electrically connected to the water inlet pipe 1102.

[0028] During normal use, if the internal temperature of the barrel 2 is too high, the temperature sensor 1104 will promptly send feedback to the water pump 1101. At this time, the water pump 1101 will start, and external water will be drawn into the spiral cooling pipe 1103 through the water inlet pipe 1102, flowing around the barrel 2, and then returning to the water storage area through the spiral cooling pipe 1103. During the water flow process, heat exchange can be carried out between the spiral cooling pipe 1103 and the barrel 2, thereby reducing the temperature of the barrel 2 and protecting the device.

[0029] This invention also provides a method for producing corn starch-based biodegradable composite lunch box extruded sheets, comprising the following steps:

[0030] S1. In the production of corn starch-based biodegradable composite lunch box extrusion sheets, firstly, the movable sleeve plate 805 is moved to insert the insertion rod 1004 into the inside of the locking hole 1003. The second motor 808 is started, causing the second motor 808 to drive the lead screw 801 to rotate, and at the same time, the threaded sleeve 804 and the movable sleeve plate 805 to rotate, thereby enabling the gear 1002 to rotate. Since the position of the gear 1002 does not change, it will block the threaded sleeve 804, preventing it from moving. This means that the threaded sleeve 804 can only rotate but cannot move. At this time, the teeth of the gear 1002 mesh with the teeth of the rack plate of the rack lifting component 1005, and the rack plate inside the rack lifting component 1005 moves upward, thereby raising the support plate 1 and driving the material cylinder 2 to rise, so as to adjust the height of the material cylinder 2. After the height adjustment is completed, the self-locking component on the rack lifting component 1005 prevents the rack plate inside the rack lifting component 1005 from moving.

[0031] S2. After height adjustment, reverse the movement of the movable sleeve 805 to move it to the position closest to the ladder platform 802. Then, rotate the locking rod 806 to engage it inside the oblong hole 807. Subsequently, start the second motor 808 to reverse the rotation of its output end. The ladder platform 802 cannot rotate due to the guide rod 9, preventing the threaded sleeve 804 from rotating. As the screw 801 engages with the threaded sleeve 804, the locking rod 806 pushes the ladder platform 802 to move, causing the top slope of the ladder platform 802 to slowly lift the lifting rod 803, thereby lifting one side of the bottom of the material cylinder 2. This achieves the purpose of changing the angle of the material cylinder 2, allowing it to better adapt to the height of the downstream production line machine.

[0032] S3. After the adjustment is completed, the raw material is added into the inside of the material cylinder 2 from the feed hopper 5. The first motor 4 is started, and the output end of the first motor 4 drives the discharge rod 3 to rotate. At the same time, the material cylinder 2 heats the material inside. Through the cooperation of the discharge rod 3 and the material cylinder 2, the material is extruded to the rear end.

[0033] During use, if the internal temperature of the barrel 2 is too high, the temperature sensor 1104 will promptly send feedback to the water pump 1101, causing the water pump 1101 to start. External water is drawn through the water inlet pipe 1102 into the interior of the spiral cooling pipe 1103, flows around the barrel 2, and returns to the water storage area through the spiral cooling pipe 1103. During the water flow process, heat exchange can be carried out between the spiral cooling pipe 1103 and the barrel 2, reducing the temperature of the barrel 2 and thus protecting the device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
