Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bag production technology, and in particular to a processing equipment for producing degradable plastic bags. Background Technology
[0002] Degradable plastic bags refer to a type of plastic bag whose various properties meet the requirements for use and can degrade into substances that are harmless to the environment under natural environmental conditions. These plastic bags do not change their properties during their shelf life, but can be decomposed by microorganisms after use, eventually turning into substances such as carbon dioxide, water and inorganic salts, without causing lasting pollution to the environment. Slitting and rewinding equipment is required in the production process of degradable plastic bags.
[0003] A search revealed a Chinese patent (authorization announcement number CN218560545U) disclosing a slitting and rewinding device for producing biodegradable plastic bags. The device includes a base plate with a frame fixed to its top. A motor-driven take-up roller is housed within the frame. A mounting bracket is fixed to the side of the frame away from the motor. The motor is mounted in a motor housing on the base plate. A fixing screw is threaded onto the mounting bracket. A hemispherical block, fitted into one side of the take-up roller, is fixed to the tail end of the fixing screw. A notch is provided on the top side of the frame away from the mounting bracket. A shaft is fixed to the take-up roller on the side of the notch, and the shaft is connected to the motor via a coupling within the notch. A detachable mounting plate is located at the top of the notch. This patented technology facilitates the removal of the take-up roller as a whole, storage of the rewound biodegradable plastic bags, and the removal of another take-up roller to complete the next rewinding operation. The biodegradable plastic bags are also flattened during the rewinding process.
[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that when the degradable plastic bag is taken out of the frame, the entire device needs to be stopped before the rewound roller can be taken out of the frame. This delays a lot of working time and reduces the production efficiency of degradable plastic bags. Utility Model Content
[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a processing equipment for the production of degradable plastic bags.
[0006] The technical solution of this utility model is as follows: a processing equipment for producing biodegradable plastic bags includes a base, two main supports are fixedly connected to the top of the base, a rotating roller is rotatably installed between the two main supports, two auxiliary supports are fixedly connected at equal intervals to the outer side of the rotating roller, a take-up roller is provided between each of the two auxiliary supports, a servo motor is fixedly installed on the outer side of one of the main supports, the output shaft of the servo motor is fixedly connected to the rotation shaft of the rotating roller, a flattening component is provided at the top of the base, a transmission component is provided at the top of the base and on one side of the flattening component, and a detachable component is provided on the outer side of the take-up roller.

[0009] In a preferred embodiment, the flattening assembly includes sliding grooves formed on both sides of the inner wall of the U-shaped frame, with sliders slidably connected inside each groove. Both ends of the top of the U-shaped frame are threadedly connected to screw rods, and the bottom ends of the screw rods extend into the interior of the sliding grooves and are rotatably connected to the corresponding sliders.
[0010] In a preferred embodiment, a second flattening roller is provided inside the U-shaped frame, and the second flattening roller is rotatably mounted between two sliders.
[0011] In a preferred embodiment, a first flattening roller is rotatably mounted inside the U-shaped frame and below the second flattening roller, and the moving block is slidably connected to the inner wall of the fixed box.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, after the first batch of biodegradable plastic bags is rewound, the output shaft of the servo motor can be rotated to drive the rotating roller to rotate, thereby rotating the rewound roller to the finished area, while the unrewound roller will rotate to the area to be rewound. During the rewinding of the current biodegradable plastic bag, the rewound roller can be detached from the sub-support, and the roller to be rewound can be installed on the sub-support. Thus, the disassembly and installation of other rollers can be completed during the rewinding process gap, thereby reducing downtime and improving the processing efficiency of biodegradable plastic bags.
[0014] In this invention, by rotating screw one, the moving block slides within the fixed box, thereby disengaging the snap-fit component on the output shaft of servo motor two from the snap-fit groove, thus facilitating the removal of the take-up roller. Conversely, reversing screw one engages the snap-fit component with the snap-fit groove, thereby enabling the take-up roller to take up the biodegradable plastic bag. Attached Figure Description

Detailed Implementation
[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0021] Reference Figure 1-4 A processing device for producing biodegradable plastic bags includes a base 1. Two main supports 5 are fixedly connected to the top of the base 1. A rotating roller 6 is rotatably mounted between the two main supports 5. Two secondary supports 9 are fixedly connected at equal intervals to the outer side of the rotating roller 6. A winding roller 7 is arranged between each of the two secondary supports 9. A servo motor 8 is fixedly mounted to the outer side of one of the main supports 5. The output shaft of the servo motor 8 is fixedly connected to the rotation shaft of the rotating roller 6. A flattening assembly is provided at the top of the base 1. A transmission assembly is provided at the top of the base 1 and on one side of the flattening assembly. A detachable assembly is provided on the outer side of the winding roller 7. When the first batch... After the biodegradable plastic bag is rewound, the output shaft of the servo motor 8 can rotate the roller 6, which in turn rotates the rewound roller 7 to the finished area, while the unrewound roller 7 will rotate to the area to be rewound. During the rewinding of the current biodegradable plastic bag, the rewound roller 7 can be detached from the sub-support 9, and the roller 7 to be rewound can be installed on the sub-support 9. Thus, the disassembly and installation of other rollers 7 can be completed during the rewinding process interval, thereby reducing downtime and improving the processing efficiency of biodegradable plastic bags.
[0022] Reference Figure 2 The detachable component includes a clamp 10 rotatably connected to one end of the sub-support 9. Half studs 14 are fixedly connected to the outer side of the clamp 10. Half studs 11 that cooperate with half studs 14 are fixedly connected to the outer side of the sub-support 9. A fixing bolt 12 is threaded between half studs 11 and half studs 14. By using the fixing bolt 12, half studs 11 and half studs 14 can be fixed together, thereby fixing both ends of the take-up roller 7 to the sub-support 9, thus achieving the purpose of removing and installing the take-up roller 7.
[0023] Reference Figure 4 The transmission assembly includes a locking groove 13 inside the shaft of the take-up roller 7. A fixed box 17 is fixedly connected to the top of the base 1. A screw 18 is threadedly connected inside the fixed box 17. A moving block is threadedly connected to the outside of the screw 18. A servo motor 16 is fixedly mounted on the top of the moving block. A locking member 15 is fixedly connected to the output shaft of the servo motor 16. The locking member 15 engages with the locking groove 13. Rotating the screw 18 causes the moving block to slide inside the fixed box 17, thereby disengaging the locking member 15 on the output shaft of the servo motor 16 from the locking groove 13, which facilitates the removal of the take-up roller 7. Reversing the screw 18 engages the locking member 15 with the locking groove 13, thereby driving the take-up roller 7 to take up the biodegradable plastic bag.
[0024] Reference Figure 3The flattening assembly includes grooves on both sides of the inner wall of the U-shaped frame 2. Sliding sliders 20 are slidably connected inside the grooves. Both ends of the top of the U-shaped frame 2 are threaded with screws 19. The bottom ends of the screws 19 extend into the grooves and are rotatably connected to the corresponding sliders 20. By rotating the screws 19, the corresponding sliders 20 can be driven to slide in the grooves, thereby adjusting the height of the flattening roller 4. Therefore, it can be used in conjunction with the flattening roller 3 to flatten biodegradable plastic bags of different thicknesses, reducing wrinkles on the biodegradable plastic bags.
[0025] Reference Figure 3 The U-shaped frame 2 is equipped with a flattening roller 4 inside. The flattening roller 4 is rotatably installed between two sliders 20. The flattening roller 4 can facilitate the flattening of the degradable plastic bag.
[0026] Reference Figure 4 Inside the U-shaped frame 2 and below the second flattening roller 4, a first flattening roller 3 is rotatably installed. The moving block is slidably connected to the inner wall of the fixed box 17. The first flattening roller 3 can cooperate with the second flattening roller 4 to ensure the flattening effect.
[0027] Working principle: First, by using the fixing bolt 12, the first half stud 11 and the second half stud 14 can be fixed together, thereby fixing both ends of the take-up roller 7 to the auxiliary bracket 9, thus realizing the purpose of removing and installing the take-up roller 7. By rotating the second screw 19, the corresponding slider 20 can be driven to slide in the groove, thereby adjusting the height of the second flattening roller 4. Therefore, it can be used in conjunction with the first flattening roller 3 to flatten biodegradable plastic bags of different thicknesses, reducing the occurrence of wrinkles in biodegradable plastic bags.
[0028] After the first batch of biodegradable plastic bags is rewound, the output shaft of the servo motor 8 can be rotated to drive the rotating roller 6 to rotate, thereby rotating the rewound roller 7 to the finished area, while the unrewound roller 7 will be rotated to the area to be rewound. During the rewinding of the current biodegradable plastic bags, the rewound roller 7 can be detached from the sub-support 9, and the roller 7 to be rewound can be installed on the sub-support 9. Thus, the disassembly and installation of other rollers 7 can be completed during the rewinding process gap, thereby reducing downtime.
[0029] Rotating screw 18 causes the moving block to slide within the fixed box 17, thereby disengaging the locking piece 15 on the output shaft of servo motor 16 from the locking groove 13, facilitating the removal of the take-up roller 7. Reversing screw 18 engages the locking piece 15 with the locking groove 13, thereby enabling the take-up roller 7 to take up the biodegradable plastic bag.
