[0004] This application provides a continuous pillow packaging machine, including a support frame. A first conveying mechanism is provided at one end of the support frame. The first conveying mechanism includes two rollers, horizontally arranged at one end of the support frame. A common conveyor chain plate is provided on the two rollers. One end of one roller is connected to a motor. A film loading roller, an adjusting mechanism, and an auxiliary roller are arranged sequentially from front to back at the bottom of the support frame. Two power mechanisms are horizontally symmetrically arranged inside the support frame. Each power mechanism consists of a power roller and a power motor. A housing is installed on the top of the support frame. A baffle is provided on each side of the housing. A film pressing mechanism, a flat pressing mechanism, a sensor, a cutting mechanism, and a [missing information] are arranged sequentially from front to back on the top of the housing. The heat shrinking mechanism includes a second conveying mechanism next to the first conveying mechanism. The second conveying mechanism includes two rollers, which are horizontally positioned in the middle of the support frame. The two rollers are equipped with the same conveyor chain plate. One end of one of the rollers is connected to a motor. An auxiliary mechanism is located next to the second conveying mechanism. The auxiliary mechanism includes an auxiliary wheel with four support blocks evenly welded to its sidewall. One end of the auxiliary wheel is connected to an auxiliary motor. A third conveying mechanism is located next to the auxiliary mechanism. The third conveying mechanism includes two rollers, which are horizontally positioned at the other end of the support frame.

[0005] Furthermore, the adjustment mechanism includes two adjustment cylinders and an adjustment roller, with the adjustment roller movably mounted at the bottom of the two adjustment cylinders.

[0006] Furthermore, the film pressing mechanism includes two film pressing cylinders and two film pressing wheels, with the two film pressing wheels fixed to the bottom of the two film pressing cylinders respectively.

[0010] Furthermore, Motor 1, Adjusting Cylinder, Film Pressing Cylinder, Film Pressing Roller, Flat Pressing Cylinder, Sensor, Cutting Cylinder, Cutting Cylinder, Heat Shrink Mechanism, Motor 2, Auxiliary Motor, and Motor 3 are all connected to the same PLC controller.

[0011] As can be seen from the above technical solution, this application provides a continuous pillow-type packaging machine, including a support frame for supporting the assembly of a first conveying mechanism, a second conveying mechanism, a third conveying mechanism, a box, a film-filling roller, an adjusting mechanism, an auxiliary roller, and a power mechanism. A first conveying mechanism is provided at one end of the support frame to transport packaging boxes containing items from the feeding area to the packaging film. The first conveying mechanism includes two rollers and a conveyor chain plate. The two rollers are horizontally arranged at one end of the support frame, and the same conveyor chain plate is provided on the two rollers for conveying. The conveyor chain plate moves under the coordinated action of a motor and the two rollers, transporting the packaging boxes containing items from the feeding area to the packaging film. One end of one of the rollers is connected to a motor. The kinetic energy output structure outputs kinetic energy, driving the roller to rotate, which in turn moves the conveyor chain, providing kinetic energy support for the operation of the first conveying mechanism. From front to back, the bottom of the support frame is equipped with a film loading roller, an adjusting mechanism, and an auxiliary roller. The film loading roller is a structure for loading rolled packaging film. The adjusting mechanism, consisting of an adjusting cylinder and an adjusting roller, plays an adjusting role. During the packaging film conveying process, the position of the adjusting roller can be adjusted through the adjusting cylinder, thereby adjusting the tension of the conveying packaging film. The auxiliary roller plays an auxiliary role, used to change the movement trajectory of the conveying packaging film and reduce friction between the packaging film and the support frame, allowing the conveying packaging film to reach the pressing mechanism without damage under the action of the power mechanism. The internal structure of the support frame is horizontal. Two symmetrically arranged power mechanisms, each consisting of a power roller and a power motor, serve a conveying function. Both power motors output kinetic energy, driving the two power rollers to rotate at high speed, using their own anti-slip cloth to continuously convey the packaging film onto the film-pressing mechanism. A box is mounted on top of the support frame, housing the film-pressing mechanism, flattening mechanism, heat-shrinking mechanism, and two baffles. A baffle is located on each side of the box, constraining the movement path of the packaging film. This allows the packaged box containing the goods to enter the moving packaging film directly. After entering the packaging film, the packaged box, wrapped in the packaging film, passes orderly and directly through the flattening mechanism, sensors, cutting mechanism, and heat shrinking mechanism. The shrink mechanism is designed for flattening, sensing, cutting, and heat shrinking. From front to back, the top of the box contains a film-pressing mechanism, a flattening mechanism, a sensor, a cutting mechanism, and a heat shrinking mechanism. The film-pressing mechanism, which performs the sealing function, consists of two film-pressing cylinders and two film-pressing rollers. The two cylinders output kinetic energy, driving the two rollers to squeeze the two sides of the packaging film from the power mechanism together. Under the action of the sealing motor, the film rotates to seal it, forming a long bag from the conveying packaging film. This allows the packaged box containing the goods above the conveying film to be placed inside the long bag, achieving the initial packaging purpose. The flattening mechanism, which performs the flattening function, consists of a flattening cylinder and a flattening plate. The flattening cylinder outputs kinetic energy to push the flattening plate to a suitable height.After the sealing mechanism presses the long bag, the vertical sealing opening is pressed flat against the bag body, providing support for subsequent cutting. The sensor detects the packaging boxes containing items and transmits the information back to the PLC controller. The PLC controller then controls the cutting mechanism to precisely cut the long bag containing the packaging boxes, effectively preventing damage to the packaging boxes. The cutting mechanism, consisting of a cutting cylinder and a cutting blade, performs the cutting action. When the sensor detects a packaging box, the cutting cylinder outputs kinetic energy to drive the cutting blade, combined with an auxiliary wheel, to cut the long bag. During the cutting process, a sealing process is applied to the cut area, thereby cutting multiple packaging boxes inside the long bag into multiple independent packaging boxes. The purpose of the film packaging box is as follows: A second conveyor is located next to the first conveyor mechanism. After the packaging box containing the goods, conveyed by the first conveyor mechanism, enters above the packaging film, it moves the packaging film and the packaging box on it together. This allows the pressing and flattening mechanisms to perform initial film wrapping during the movement of the packaging box. The second conveyor mechanism includes two rollers (II) and a conveyor chain plate (II). The two rollers (II) are horizontally positioned in the middle of the support frame, and both rollers (II) are equipped with the same conveyor chain plate (II) for conveying. They move under the coordinated action of a motor (II) and the two rollers (II), transporting the packaging box containing the packaging film from the first conveyor mechanism to the cutting mechanism. One end of one of the rollers (II) is connected to a motor (II). The first conveyor has an output structure that provides kinetic energy support for the second conveyor's operation. An auxiliary mechanism is located next to the second conveyor, including an auxiliary wheel with four support blocks evenly welded to its sidewall. Driven by an auxiliary motor, the auxiliary wheel rotates, causing the support blocks to rotate along it. This ensures the blocks regularly contact the cutter when sealing long bags, assisting in the sealing process. During rotation, the blocks are cut and sealed into individual packaging boxes, which are then transferred to the third conveyor. An auxiliary motor is connected to one end of the auxiliary wheel, providing kinetic energy support for its operation. The third conveyor is located next to the auxiliary mechanism. The first mechanism transports individually packaged boxes, fed by auxiliary wheels, from the cutting mechanism to the collection area. During transport, the boxes pass through a heat-shrinking mechanism for heat shrinking. The second mechanism includes two rollers with a conveyor chain plate. These rollers are horizontally positioned at the other end of the support frame and share the same conveyor chain plate. Moving in coordination with the motor and rollers, they transport the individually packaged boxes from the cutting mechanism to the collection area. One end of one roller is connected to the motor, providing kinetic energy for the operation of the third mechanism.

[0012] In summary, the beneficial effects of this application are as follows:

[0013] 1. Through intelligent control of multi-stage conveying mechanism and adjustable adjustment device, efficient coordination between multi-stage conveying mechanism and mechanisms such as film pressing, cutting and heat shrinking is realized, which not only improves packaging efficiency and packaging accuracy, but also enhances the continuity and adaptability of production.

[0014] 2. The film pressing mechanism, flat pressing mechanism, and cutting mechanism all adopt cylinder adjustment. By adjusting the working area of ​​the film pressing wheel, flat pressing plate, and cutter, adjustable mechanical film coating is achieved, which can coat different products and improve the practicality of the equipment.

[0015] 3. An adjustment mechanism is provided, which allows for electric adjustment of the tension of the packaging film at any time. This not only makes the operation simple and convenient, but also reduces the intensity of manual labor. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] From the above technical solutions, it can be seen that:

[0023] Example 1:

[0024] See Figure 1 , Figure 2 。

[0025] A continuous pillow-type packaging machine includes a support frame 1, which provides support and is used for assembling a first conveying mechanism, a second conveying mechanism, a third conveying mechanism, a housing 9, a film-filling roller 5, an adjusting mechanism, an auxiliary roller 8, and a power mechanism 29. The first conveying mechanism is located at one end of the support frame 1, transporting boxes containing goods from the feeding area to the packaging film. The first conveying mechanism includes two roller shafts 2 and a conveyor chain plate 3. The two roller shafts 2 are horizontally positioned at one end of the support frame 1, and the same conveyor chain plate 3 is mounted on both roller shafts 2 for conveying. The conveyor chain plate 3 moves under the coordinated action of a motor 4 and the two roller shafts 2, transporting the boxes containing goods from the feeding area to the packaging film. One end of one roller shaft 2 is connected to the motor 4, which provides kinetic energy. The output structure outputs kinetic energy, driving the roller 2 to rotate, thereby moving the conveyor chain 3 and providing kinetic energy support for the operation of the first conveying mechanism. From front to back, the bottom of the support frame 1 is equipped with a film loading roller 5, an adjusting mechanism, and an auxiliary roller 8. The film loading roller 5 is a structure for loading rolled packaging film. The adjusting mechanism, consisting of an adjusting cylinder 6 and an adjusting roller 7, plays an adjusting role. During the packaging film conveying process, the position of the adjusting roller 7 can be adjusted through the adjusting cylinder 6 to adjust the tension of the conveying packaging film. The auxiliary roller 8 plays an auxiliary role, changing the movement trajectory of the conveying packaging film and reducing friction between the packaging film and the support frame 1, allowing the conveying packaging film to reach the pressing mechanism without damage under the action of the power mechanism 29. The support frame 1 has two horizontally symmetrically arranged power mechanisms 29. Each power mechanism 29 consists of a power roller and a power motor, which serve as a conveyor. Both power motors output kinetic energy to drive the two power rollers to rotate at high speed using their own anti-slip cloth to continuously convey the packaging film on the film-loading rollers to the area below the film-pressing mechanism. A box 9 is installed on the top of the support frame 1, which houses the film-pressing mechanism, flattening mechanism, heat shrinking mechanism 17, and two baffles 30. A baffle 30 is installed on each side of the box 9 to constrain the movement path of the packaging film, allowing the packaged box containing the goods to enter the moving packaging film directly. After the packaged box containing the goods enters the packaging film, it ensures that the packaged box wrapped in the packaging film moves in an orderly manner. The packaging film is directly processed by a flattening mechanism, a sensor 14, a cutting mechanism, and a heat shrinking mechanism 17. The top of the housing 9, from front to back, is equipped with a film pressing mechanism, a flattening mechanism, a sensor 14, a cutting mechanism, and a heat shrinking mechanism 17. The film pressing mechanism, which performs the sealing function, consists of two film pressing cylinders 10 and two film pressing wheels 12. The two film pressing cylinders 10 output kinetic energy, driving the two film pressing wheels 12 to squeeze the two sides of the packaging film delivered by the power mechanism 29 together. Under the action of the sealing motor, the film is rotated to perform the sealing process, forming a long bag from the conveying packaging film. This allows the packaging box containing the items above the conveying packaging film to be placed inside the long bag, achieving the initial packaging purpose. The flattening mechanism performs the flattening function.The system consists of a flat-press cylinder 11 and a flat-press plate 13. The flat-press cylinder 11 outputs kinetic energy to push the flat-press plate 13 to a suitable height, pressing the vertical sealing opening of the long bag body after the film-sealing mechanism is pressed flat, providing support for subsequent cutting. The sensor 14 acts as a sensor to detect the packaging box containing the goods and transmits the sensed information back to the PLC controller 28, so that the PLC controller 28 can control the operation of the cutting mechanism to accurately cut the long bag containing the packaging box, effectively preventing damage to the packaging box. The cutting mechanism, which performs the cutting function, consists of a cutting cylinder 15 and a cutting blade 16. When the sensor 14 detects the packaging box, its cutting cylinder 15 outputs kinetic energy to drive the cutting blade 16 in conjunction with the auxiliary wheel 21 to cut the long bag. During the cutting process, the cut ends are sealed to separate multiple packaging boxes inside the long bag into multiple independent packaging boxes with packaging films. A second conveying mechanism is located next to the first conveying mechanism. When the packaging boxes containing items are conveyed by the first conveying mechanism and enter above the packaging film, they move together with the packaging film and the boxes on it, facilitating the initial wrapping process by the pressing and flattening mechanisms. The second conveying mechanism includes two roller shafts 18 and rollers with conveyor chain plates 19. The two roller shafts 18 are horizontally positioned in the middle of the support frame 1, and the same conveyor chain plate 19 is installed on both roller shafts 18 for conveying. The motor 20 works in conjunction with the two roller shafts 18. The lowering mechanism transports the packaging box containing the packaging film from the first conveyor to the cutting mechanism. One end of a roller 18 is connected to a motor 20, which provides kinetic energy output to support the conveying operation of the second conveyor. An auxiliary mechanism is set next to the second conveyor, including an auxiliary wheel 21. Four support blocks 22 are evenly welded to the side wall of the auxiliary wheel 21 for auxiliary purposes. Driven by the auxiliary motor 23, the auxiliary wheel 21 rotates, causing the multiple support blocks 22 on the auxiliary wheel 21 to rotate along the auxiliary wheel 21. This allows the support blocks 22 to regularly adhere to the cutter 16 when cutting and sealing long bags, assisting the cutter 16 in cutting and sealing long bags. During the rotation, the cutter 16 cuts and seals the long bags into individual packages. The packaging box is pushed onto the third conveying mechanism. One end of the auxiliary wheel 21 is connected to the auxiliary motor 23, which is a kinetic energy output structure that provides kinetic energy support for the operation of the auxiliary wheel 21. The third conveying mechanism is set up next to the auxiliary mechanism to transport the individually packaged boxes pushed by the auxiliary wheel 21 from the cutting mechanism to the collection area. During the conveying process, the individually packaged boxes pass through the heat shrinking mechanism 17 to perform heat shrinking treatment on the individually packaged boxes. The third conveying mechanism includes two roller shafts 24 and rollers with conveyor chain plates 25. The two roller shafts 24 are horizontally set at the other end of the support frame 1. The two roller shafts 24 are equipped with the same conveyor chain plate 25, which plays a conveying role and moves under the cooperative action of the motor 26 and the roller shafts 24.The individually packaged boxes, fed by the auxiliary wheel 21, are conveyed from the cutting mechanism to the collection area. One end of one of the rollers 24 is connected to a motor 26, a kinetic energy output structure that provides kinetic energy support for the operation of the third conveying mechanism.

[0026] In a preferred embodiment, the adjustment mechanism includes two adjustment cylinders 6 and an adjustment roller 7. The adjustment roller 7 is movably mounted at the bottom of the two adjustment cylinders 5, providing strong support for the electric adjustment of the packaging film tension.

[0027] In a preferred embodiment, the film pressing mechanism includes two film pressing cylinders 10 and two film pressing wheels 12. The two film pressing wheels 12 are respectively fixed to the bottom of the two film pressing cylinders 10. The two film pressing wheels 12 are symmetrically arranged. During the packaging process of the packaging box, the two sides of the packaging film can be squeezed and sealed together to form a long bag. The packaging box is then allowed to enter the long bag under the action of the first conveying mechanism and the second conveying mechanism to achieve the purpose of initial film wrapping of the packaging box.

[0028] In a preferred embodiment, the flattening mechanism includes a flattening cylinder 11 and a flattening plate 13. The flattening plate 13 is fixed to the bottom of the flattening cylinder 11, providing strong support for the electric adjustment of the flattening mechanism.

[0029] In a preferred embodiment, the cutting mechanism includes a cutting cylinder 15 and a cutting blade 16. The cutting blade 16 is fixed to the bottom of the cutting cylinder 45, providing strong support for the electric adjustment of the cutting mechanism.

[0030] In a preferred embodiment, a plurality of legs 27 are welded to the bottom of the support frame 1 to support the support frame 1.

[0031] In a preferred embodiment, motor 4, adjusting cylinder 6, film pressing cylinder 10, film pressing wheel 12, flat pressing cylinder 11, sensor 14, cutting cylinder 15, cutting knife 16, heat shrinking mechanism 17, motor 20, auxiliary motor 23, and motor 3 26 are all connected to the same PLC controller 28. By using the PLC control system to intelligently control the multi-stage conveying mechanism and the adjustable adjustment device, the efficient coordination of the multi-stage conveying mechanism with the film pressing, cutting, and heat shrinking mechanisms is realized. This not only improves packaging efficiency and packaging accuracy but also enhances the continuity and adaptability of production.
