[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0030] A folding and laminating machine for woven tubular bags includes a folding frame 1. Two fixed frames 2 are fixedly installed on the bottom inner side of the folding frame 1. A rotating shaft 3 is passed through the bottom of the inner cavity of the fixed frame 2. The bottom end of the rotating shaft 3 extends to the bottom of the folding frame 1. A ratchet 7 located inside the fixed frame 2 is fixedly installed on the surface of the rotating shaft 3. A pawl 8 adapted to the ratchet 7 is passed through one side of the fixed frame 2. A spring 9 is sleeved on the surface of the pawl 8. The two ends of the spring 9 are fixedly connected to the fixed frame 2 and the pawl 8, respectively. A rotating frame 4 is fixedly installed at the top of the rotating shaft 3. A rotating roller assembly 6 is rotatably installed on the inner side of the rotating frame 4. A stepper motor 5 is fixedly installed on the outer side of one of the rotating frames 4. The output shaft of the stepper motor 5 extends through the interior of the corresponding rotating frame 4 and is fixedly connected to the rotating roller assembly 6.

[0031] The specific usage process is as follows: When it is necessary to move or transport the laminating machine, the user first removes the film roll 14 from the machine. Because the rotating end rod 15 and the film roll 14 are threadedly connected, the film roll 14 can be disassembled by rotating it off the rotating end rod 15, just like inserting a screw. This is existing technology. Then, the film roll 14 and the rotating end rod 15 can be removed from the machine. There are a total of four sets of film rolls 14 and rotating end rods 15 on the machine. All of them must be removed during disassembly. Then, rotate the rotating shaft rod 3. The fixing frame 2 is fixedly installed on the folding frame 1. Therefore, when the rotating shaft rod 3 rotates, it will drive the ratchet 7 to rotate inside the fixing frame 2. At the same time, the rotating shaft rod 3 will also drive the rotating frame 4 to rotate. The stepper motor 5 and the rotating shaft rod 4 are mounted on the rotating frame 4. The rotating roller assembly 6 will also rotate along with it, rotating counterclockwise by 90 degrees until it is parallel to the side frame 101. At this point, short roller 1 61 and short roller 2 62 will separate, and the locking block 64 will move out of the locking slot 63. It should be noted that the rotating shaft 3 on the other side also rotates in the same way, and short roller 2 62 also rotates counterclockwise until it is parallel to the side frame 2 102. It should be noted that the pressure roller 13 has the same structure as the rotating roller assembly 6, and it will also be divided into two parts when folded. It will also rotate counterclockwise along with the rotating frame 4 and be adjusted synchronously with the rotating roller assembly 6. When the rotating frame 4 rotates, the guide rail 10 and all components mounted on it also rotate. The guide rail 10 rotates along with the rotating frame 4. It should be noted that when rotating the rotating shaft 3, the pawl 8 must first be pulled outwards so that the wedge-shaped end of the pawl 8 moves out of the teeth on the ratchet 7. This is because the end of the pawl 8 that is engaged with the teeth on the ratchet 7 has an inclined surface. When the ratchet 7 rotates clockwise to unfold, the teeth can slide over the inclined surface on the pawl 8 without being obstructed by the pawl 8, making the unfolding of the machine labor-saving, convenient, and easy to operate. Conversely, when the ratchet 7 rotates counterclockwise, without the inclined surface, it will be obstructed by the pawl 8 and unable to rotate. Therefore, when rotating the rotating shaft 3, the pawl must first be pulled outwards. Pulling pawl 8 outwards simultaneously stretches spring 9, allowing the rotating roller assembly 6 to move freely while in operation, ensuring the stability of the laminating machine. The pressure roller 13 operates similarly; refer to the ratchet mechanism for details. Once both the rotating roller assembly 6 and the pressure roller 13 are in position, the movable plate 103 can be pressed downwards. The end of the movable plate 103 within the fixed rail 105 will press down spring 106 until the movable plate 103 is lower than the height of the side frame 101. Then, the side frame 102 can be pushed towards the side frame 101, and the support rod 104 will slide into the side frame 101, completing the folding process of the laminating machine. This reduces the overall size of the laminating machine by half.The movable plate 103 will also move to the bottom of the side frame 101. At this time, the machine will not occupy too much space when it is moved onto the transport vehicle, increasing the space utilization rate by 50% and providing convenience for the user's transportation work. During the deployment, the folded machine is first moved into the factory to reduce the restriction of obstacles and facilitate the user's handling. After the machine is moved to a suitable position, the folding frame 1 is unfolded. During the unfolding operation, the side frame 2 102 is pulled outward until the movable plate 103 leaves the bottom of the side frame 101. At the same time, the support rod 104 will also move out of the side frame 101 along with the side frame 2 102, but will not detach from the side frame 101. At this time, under the action of the spring 2 106, the movable plate 103 will move outward. 03 pops up and is at the same horizontal height as side frame 101. This allows the movable plate 103 to be locked between side frame 101 and side frame 2 102, ensuring the stability of the machine after unfolding. After the folding frame 1 is fully unfolded, the rotating shaft 3 is rotated clockwise. The rotating shaft 3 drives the ratchet 7 to rotate on the fixed frame 2. Simultaneously, the rotating frame 4, the stepper motor 5 mounted on the rotating frame 4, and the rotating roller assembly 6 will also rotate. Short roller 1 61 and short roller 2 62 rotate towards each other. Then, short roller 1 61 and short roller 2 62 align, and the locking block 64 engages with the locking slot 63 to form a complete rotating roller assembly 6. With the cooperation of the locking block 64 and the locking slot 63, short roller 1 61 and short roller 2 62 will rotate synchronously. Similarly, the two separate parts are pressed... Roller 13 will also be assembled simultaneously. When ratchet 7 rotates clockwise, its teeth will contact the inclined surface of pawl 8, thus directly squeezing and pushing pawl 8 to move outwards towards the fixed frame 2. Simultaneously, pawl 8 stretches spring 9, ensuring that pawl 8 does not affect the rotation of ratchet 7. After ratchet 7 finishes rotating, the end of pawl 8 will return to its original position under the action of spring 9, locking back into the teeth of ratchet 7, thereby restricting ratchet 7 and preventing it from moving arbitrarily. This ensures the stability of the rotating roller assembly 6 and pressure roller 13, providing convenience for the user's setup and assembly work. This completes the unfolding and setup of the laminating machine. Finally, the film roll roller 14 and rotating end rod 15 are installed in their corresponding positions, and the machine can then be put into normal operation. In this system, the two pressure rollers 13 are rotatably mounted on two sliding blocks 12, allowing the pressure rollers 13 to be adjusted vertically along with the sliding blocks 12. This enables the machine to coat materials of different thicknesses. During adjustment, rotating the adjusting screw 11 moves the sliding blocks 12 within the guide rail 10, causing the pressure rollers 13 to move vertically accordingly. It should be noted that when adjusting the pressure rollers 13, the adjusting screws 11 on both sides should be rotated alternately to ensure smooth adjustment. It should also be noted that, for operational needs, another drive motor capable of rotating synchronously with the stepper motor 5 can be mounted on another rotating frame 4 to meet specific work requirements.The specific configuration can be determined by the user based on actual usage needs. The rotating roller assembly 6 consists of two parts: short roller 1 61 and short roller 2 62. During machine folding, short roller 1 61 and short roller 2 62 will separate, and the locking block 64 will move out of the slot 63 to ensure smooth folding. During unfolding, short roller 1 61 and short roller 2 62 will merge together, and the locking block 64 will engage with the slot 63 to form a complete rotating roller assembly 6, ensuring the normal operation of the machine's film coating process and providing convenience for the user. The guide rail 10, adjusting screw 11, sliding block 12, and pressure roller 13 are also included. The sliding block 12 is used to adjust the height of the pressure roller 13, thus adjusting the distance between the pressure roller 13 and the rotating roller assembly 6. This allows the laminating machine to meet the laminating needs of materials of different thicknesses, providing convenience for users. During adjustment, rotating the adjusting screw 11 causes the sliding block 12 to move within the guide rail 10, and the pressure roller 13 moves up and down accordingly, thereby adjusting the pressure roller 13. It should be noted that when adjusting the pressure roller 13, the adjusting screws 11 on both sides should be rotated alternately to ensure smooth adjustment. The two ends of the movable plate 103 are respectively mounted on two fixed rails 105. The sliding mechanism ensures the vertical movement of the movable plate 103. Spring 106 provides thrust when the machine unfolds and the movable plate 103 moves upward, assisting and facilitating the user's machine unfolding. When the machine is unfolded, the movable plate 103 is positioned between side frame 101 and side frame 102, supporting them and ensuring the stability of the folding frame 1 during unfolding, thus providing convenience for the user. The support rod 104 is fixedly mounted on side frame 102 and also movably mounted on side frame 101, thus not affecting... The folding of side frame 2 102 and side frame 101 provides support and connection for side frame 101 and side frame 2 102, ensuring they do not separate and facilitating user operation. The groove on the movable plate 103 is for placing the support rod 104. The film roll 14 is used to install the film roll, and the rotating end rod 15 is threadedly connected to the film roll 14. Therefore, disassembling the film roll 14 by first removing the rotating end rod 15 allows for quick removal of the film roll 14, and installation is similar, thus facilitating user assembly and disassembly.

[0032] Therefore, a foldable and volume-reducing structural design is adopted, upgrading and optimizing the traditional laminating structure into a foldable structure. This makes the laminating machine more flexible and convenient in transportation and deployment, reducing the space occupied during transportation, reducing the time spent on machine assembly, improving the efficiency of transportation, assembly and deployment of the laminating machine, and providing convenience for users' work.

[0033] The rotating roller assembly 6 includes a first short roller 61 and a second short roller 62, which are respectively rotatably installed in two rotating frames 4. The output shaft of the stepper motor 5 is fixedly connected to the first short roller 61. One end of the first short roller 61 is provided with a slot 63, and one end of the second short roller 62 is fixedly connected with a locking block 64 that matches the slot 63.

[0034] Specifically, the rotating roller assembly 6 is composed of two parts: short roller 1 61 and short roller 2 62. When the machine folds, short roller 1 61 and short roller 2 62 will separate, and the locking block 64 will move out of the locking groove 63 to ensure the smooth progress of the folding operation. When unfolding, short roller 1 61 and short roller 2 62 will merge together, and the locking block 64 will lock into the locking groove 63 to form a complete rotating roller assembly 6, ensuring the normal operation of the machine's film coating work and providing convenience for users.

[0035] A guide rail 10 is fixedly installed on the top of the rotating frame 4. An adjusting screw 11 is provided inside the guide rail 10. The bottom end of the adjusting screw 11 is rotatably installed on the rotating frame 4. A sliding block 12 that slides inside the guide rail 10 is threaded onto the surface of the adjusting screw 11. A pressure roller 13 is rotatably installed between the two sliding blocks 12.

[0036] Specifically, the guide rail 10, adjusting screw 11, and sliding block 12 are configured together with the pressure roller 13. The guide rail 10, adjusting screw 11, and sliding block 12 are used to adjust the height of the pressure roller 13. In this way, the distance between the pressure roller 13 and the rotating roller assembly 6 can be adjusted, enabling the laminating machine to meet the laminating processing of materials of different thicknesses and providing convenience for users. When adjusting, rotating the adjusting screw 11 will drive the sliding block 12 to move within the guide rail 10, and the pressure roller 13 will also move up and down accordingly, thereby realizing the adjustment of the pressure roller 13. It should be noted that when adjusting the pressure roller 13, the adjusting screws 11 on both sides should be rotated alternately in sequence to ensure the smooth progress of the adjustment work.

[0037] The folding frame 1 includes a side frame 101 and a side frame 2 102 arranged opposite to each other. Both ends of the inner side of the side frame 2 102 are fixedly connected to fixed rails 105. A movable plate 103 is provided between the side frame 101 and the side frame 2 102. Both ends of the movable plate 103 are slidably installed in the two fixed rails 105 respectively.

One end of the springs 2 106 is fixedly connected to the inner wall of the corresponding fixed rail 105.

[0038] Specifically, the side frame 101, side frame 2 102, movable plate 103, fixed rail 105, and spring 2 106 are arranged such that both ends of the movable plate 103 slide within the two fixed rails 105, thus ensuring the movable plate 103 moves vertically up and down. Spring 2 106 provides thrust when the machine is unfolded and the movable plate 103 moves upward, providing assistance and convenience for the user to unfold the machine. When the machine is unfolded, the movable plate 103 is located between side frame 101 and side frame 2 102, which can support side frame 101 and side frame 2 102, ensuring the stability of the folding frame 1 when unfolded, and providing convenience for the user's work.

[0039] A plurality of support rods 104 are fixedly installed on one side of the second side frame 102. The plurality of support rods 104 are slidably installed inside the first side frame 101. The top of the movable plate 103 is provided with a groove that matches the plurality of support rods 104.

[0040] Specifically, the support rod 104 is fixedly installed on the second side frame 102 and also movably installed on the first side frame 101. This arrangement does not affect the folding of the second side frame 102 and the first side frame 101, while providing support and connection between the first side frame 101 and the second side frame 102, ensuring that the first side frame 101 and the second side frame 102 do not separate, thus providing convenience for the user's operation. The groove on the movable plate 103 is used to place the support rod 104.

[0041] A film roll 14 is provided at the top between the first side frame 101 and the second side frame 102. Both ends of the film roll 14 are threaded with rotating end rods 15, and the two rotating end rods 15 are respectively rotatably installed inside the first side frame 101 and the second side frame 102.

[0042] Specifically, the membrane roll 14 and the rotating end rod 15 are configured such that the membrane roll 14 is used to install the membrane roll, and the rotating end rod 15 is connected to the membrane roll 14 by a threaded connection. Therefore, when disassembling the membrane roll 14, the rotating end rod 15 can be removed first to quickly remove the membrane roll 14. The same applies to installation, thus providing convenience for users' disassembly and assembly work.
