[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A bag-making machine includes a base 1, on which symmetrical vertical frames 2 are fixedly installed. Electric push rods 3 are fixedly installed at both ends of the outer sides of the vertical frames 2, and horizontal frames 4 are fixedly installed at both ends of the inner sides of the vertical frames 2. Movable blocks 5 are slidably arranged on each horizontal frame 4. The output shaft ends of the electric push rods 3 are fixedly installed to the sides of the movable blocks 5. Movable columns 6 are hingedly installed on each movable block 5. Symmetrical movable plates 7 are slidably arranged on the inner sides of the vertical frames 2, with the ends of the movable columns 6 hingedly arranged on the movable plates 7. Symmetrical ironing strips 8 are arranged between the two sets of vertical frames 2, and the two sets of ironing strips 8 are respectively arranged on the movable plates 7.

[0031] In use, the base 1 is used to support the entire device, and the device is fixedly installed on the bag making machine via the base 1. During the bag making process, the bag body is conveyed between two sets of heat sealing strips 8;

[0032] When it is necessary to bring the two sets of ironing strips 8 closer together for ironing, the electric push rods 3 at both ends of the outer sides of the two sets of vertical frames 2 are activated simultaneously. The output shafts of the electric push rods 3 extend outward. Since the ends of the output shafts of the electric push rods 3 are fixedly installed on the sides of the movable blocks 5 that are slidably set on the horizontal frame 4, the movable blocks 5 will slide along the horizontal frame 4 under the push of the electric push rods 3. At the same time, movable columns 6 are hinged to the movable blocks 5. The ends of the movable columns 6 are respectively hinged to the movable plates 7 that are slidably set on the inner side of the vertical frame 2. As the movable blocks 5 move, the movable columns 6 will rotate and push the movable plates 7 to slide closer together on the inner side of the vertical frame 2, thereby driving the two sets of ironing strips 8 set on the movable plates 7 to move closer together. During the bag conveying process, the bag is stably bonded and ironed. When the ironing operation is completed, the output shafts of the electric push rods 3 retract inward at the same time. Through the linkage of the movable blocks 5 and the movable columns 6, the movable plates 7 drive the two sets of ironing strips 8 away from each other, achieving stable separation, effectively reducing the occurrence of ironing bag adhesion, and ensuring the continuity and stability of the ironing process.

[0033] The two sets of vertical frames 2 are equipped with symmetrical support rollers 9 on one side for joint rotation;

[0034] Two sets of vertical frames 2 are equipped with symmetrical support rollers 9 that rotate together on one side. When the bag making machine conveys the bag body to the hot stamping equipment, the bag body first passes through the support rollers 9. When the bag body comes into contact with the support rollers 9, the support rollers 9 will rotate with the movement of the bag body, thereby supporting and guiding the bag body, so that the bag body can be continuously and stably conveyed between the two sets of hot stamping strips 8, further improving the stability of the hot stamping process.

[0035] A symmetrical box 10 is fixedly installed on the side of the vertical frame 2 away from the support roller 9. Filter plates 11 are provided on the top and bottom surfaces of the box 10. Cooling fans that are evenly distributed are fixedly installed inside the box 10.

[0036] After the bag passes through two sets of heat-sealing strips 8, the pressing area then passes between two sets of boxes 10. The pressing area is at a high temperature, so the cooling fan inside the box 10 is activated. The cooling fan starts to rotate, generating airflow. The airflow enters the box 10 from the filter plate 11 on the bottom surface of the box 10. After being accelerated by the cooling fan, the airflow is blown out from the filter plate 11 on the top surface of the box 10, directly acting on the pressing area after the bag is heat-sealed, dissipating heat and cooling the pressing area, reducing the bag temperature, and reducing problems such as deformation of the bag during subsequent cutting.

[0037] The filter plates 11 are all snapped onto the box body 10;

[0038] When the filter plate 11 needs to be cleaned or replaced, since the filter plate 11 and the box 10 are connected by a snap-fit ​​mechanism, the operator only needs to apply appropriate external force to overcome the clamping force of the snap-fit ​​structure to remove the filter plate 11 from the box 10 and complete the disassembly operation. After cleaning or replacement, the new filter plate 11 is aligned with the snap-fit ​​position on the box 10, and a certain pressure is applied to make the filter plate 11 snap-fit ​​and fixed on the box 10 again, achieving simple installation and facilitating easy disassembly and assembly of the filter plate 11. This allows the operator to regularly clean, maintain or replace the filter plate 11, ensuring the normal working effect of the cooling fan.

[0039] Each movable plate 7 is provided with a connection port 12, the size of which is adapted to the size of the ironing strip 8, and the ironing strip 8 is fixedly installed to the movable plate 7 by screws;

[0040] During the bag production process, depending on the different bag sizes and hot stamping requirements, it may be necessary to replace the hot stamping strip 8 with different sizes. When it is necessary to replace the hot stamping strip 8, the worker only needs to use a tool to unscrew the screws that fix the hot stamping strip 8 to the movable plate 7, and then remove the hot stamping strip 8 from the connection port 12 of the movable plate 7 to complete the disassembly operation. Then, the hot stamping strip 8 of the appropriate size is placed into the connection port 12, and the hot stamping strip 8 is fixed to the movable plate 7 with screws. This achieves simple installation and facilitates easy disassembly and assembly of the hot stamping strip 8, thereby facilitating the replacement of hot stamping strips 8 of different sizes, improving the applicability of the device, and meeting diverse production needs.

[0041] A damping mechanism is provided between the heat exchange strip 8 and the connector 12;

[0042] Damping is provided between the ironing strip 8 and the connecting port 12. When the ironing strip 8 is installed into the connecting port 12 of the movable plate 7 and fixed with screws, the damping between the ironing strip 8 and the connecting port 12 will generate a certain friction force. The friction force can resist the external forces such as vibration and impact that the ironing strip 8 may be subjected to during the operation of the equipment, so that the ironing strip 8 can be more stably kept in the connecting port 12 after installation and fixation, and will not easily loosen or shift, thereby improving the stability of the ironing strip 8 after installation and fixation, and ensuring the quality and stability of the ironing bag operation.

[0043] The outer wall of the electric push rod 3 is equipped with a protective shell;

[0044] All electric push rods 3 are equipped with protective shells on their outer walls. During the hot-pressing operation of the bag making machine, the hot-pressing strip 8 generates a high temperature when pressing the bag body, and the ambient temperature will also rise accordingly. The protective shells on the outer walls of the electric push rods 3 can play a role in heat insulation and protection, isolating the electric push rods 3 from the high-temperature environment, reducing the direct radiation and conduction of high temperature to the electric push rods 3, thereby effectively protecting the electric push rods 3 and ensuring that the electric push rods 3 can work normally in a suitable temperature environment, improving the overall reliability and service life of the device.

[0045] Working principle:

[0046] In use, the base 1 is used to support the entire device, and the device is fixedly installed on the bag making machine via the base 1. During the bag making process, the bag body is conveyed between two sets of heat sealing strips 8;

[0047] When it is necessary to bring the two sets of ironing strips 8 closer together for ironing bag operation, the electric push rods 3 at both ends of the outer side of the two sets of vertical frames 2 are activated simultaneously. The output shaft of the electric push rod 3 extends outward. Since the ends of the output shaft of the electric push rod 3 are fixedly installed on the side of the movable block 5 that is slidably set on the horizontal frame 4, the movable block 5 will slide along the horizontal frame 4 under the push of the electric push rod 3. At the same time, the movable column 6 is hinged on the movable block 5. The ends of the movable column 6 are respectively hinged to the movable plate 7 that is slidably set on the inner side of the vertical frame 2. As the movable block 5 moves, the movable column 6 will rotate and push the movable plate 7 to slide closer together on the inner side of the vertical frame 2, thereby driving the two sets of ironing strips 8 set on the movable plate 7 to move closer together. During the bag conveying process, the bag is stably bonded and ironed. When the ironing bag operation is completed, the output shaft of the electric push rod 3 retracts inward at the same time. Through the linkage of the movable block 5 and the movable column 6, the movable plate 7 drives the two sets of ironing strips 8 to move away from each other, achieving stable separation, effectively reducing the occurrence of ironing bag adhesion, and ensuring the continuity and stability of the ironing bag process.

[0048] in,

[0049] Two sets of vertical frames 2 are equipped with symmetrical support rollers 9 on one side. When the bag making machine conveys the bag body to the hot stamping equipment, the bag body first passes through the support rollers 9. When the bag body contacts the support rollers 9, the support rollers 9 will rotate with the movement of the bag body, thereby supporting and guiding the bag body, so that the bag body can be continuously and stably conveyed between the two sets of hot stamping strips 8, further improving the stability of the hot stamping process.

[0050] After the bag passes through two sets of ironing strips 8, the pressing part then passes between two sets of boxes 10. The pressing part is at a high temperature, so the cooling fan inside the box 10 is activated. The cooling fan starts to rotate and generates airflow. The airflow enters the box 10 from the filter plate 11 on the bottom surface of the box 10. After being accelerated by the cooling fan, the airflow is blown out from the filter plate 11 on the top surface of the box 10, directly acting on the pressing part after the bag is ironed, dissipating heat and cooling the pressing part, reducing the temperature of the bag, and reducing problems such as deformation of the bag during the subsequent cutting process.

[0051] When the filter plate 11 needs to be cleaned or replaced, since the filter plate 11 and the box 10 are connected by a snap-fit ​​connection, the operator only needs to apply appropriate external force to overcome the clamping force of the snap-fit ​​structure to remove the filter plate 11 from the box 10 and complete the disassembly operation. After cleaning or replacement, the new filter plate 11 is aligned with the snap-fit ​​position on the box 10 and a certain pressure is applied to make the filter plate 11 snap-fit ​​and fixed on the box 10 again, which realizes simple installation and facilitates easy disassembly and assembly of the filter plate 11. This makes it convenient for the operator to clean, maintain or replace the filter plate 11 regularly and ensure the normal working effect of the cooling fan.

[0052] During the bag making process, depending on the different bag sizes and hot stamping requirements, it may be necessary to replace the hot stamping strip 8 with different sizes. When it is necessary to replace the hot stamping strip 8, the worker only needs to use a tool to unscrew the screws that fix the hot stamping strip 8 to the movable plate 7, and then remove the hot stamping strip 8 from the connection port 12 of the movable plate 7 to complete the disassembly operation. Then, the hot stamping strip 8 of the appropriate size is placed into the connection port 12, and the hot stamping strip 8 is fixed to the movable plate 7 with screws. This achieves simple installation and facilitates easy disassembly and assembly of the hot stamping strip 8, thereby facilitating the replacement of hot stamping strips 8 of different sizes, improving the applicability of the device, and meeting diverse production needs.

[0053] Damping is provided between the ironing strip 8 and the connecting port 12. When the ironing strip 8 is installed into the connecting port 12 of the movable plate 7 and fixed with screws, the damping between the ironing strip 8 and the connecting port 12 will generate a certain friction force. The friction force can resist the external forces such as vibration and impact that the ironing strip 8 may be subjected to during the operation of the equipment, so that the ironing strip 8 can be more stably kept in the connecting port 12 after installation and fixation, and will not easily loosen or shift, thereby improving the stability of the ironing strip 8 after installation and fixation, and ensuring the quality and stability of the ironing bag operation.

[0054] All electric push rods 3 are equipped with protective shells on their outer walls. During the hot-pressing operation of the bag making machine, the hot-pressing strip 8 generates a high temperature when pressing the bag body, and the ambient temperature will also rise accordingly. The protective shells on the outer walls of the electric push rods 3 can play a role in heat insulation and protection, isolating the electric push rods 3 from the high-temperature environment, reducing the direct radiation and conduction of high temperature to the electric push rods 3, thereby effectively protecting the electric push rods 3 and ensuring that the electric push rods 3 can work normally in a suitable temperature environment, improving the overall reliability and service life of the device.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
