Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Vertically upward mounting plates are fixed on both sides of the first conveying platform 110, and a plurality of mounting holes are arranged up and down on the mounting plates. The second conveying platform 120 can be detachably mounted in any mounting hole by bolts. By fixing the second conveying platform 120 in mounting holes at different heights, the height of the outlet end of the first channel can be adjusted to compress the pillow core to different degrees.

[0053] A first sensor 111 is provided at the front end of the first conveying platform 110 for detecting whether there is a pillow core at the front end thereof, and a second sensor 112 is provided at the rear end of the first conveying platform 110 for detecting whether there is a pillow core at the rear end thereof. Both the first sensor 111 and the second sensor 112 are connected to the signal input end of the controller.

[0054] When the first sensor 111 detects that there is a pillow core at the front end of the first conveying platform 110, the controller controls the first conveying platform 110 to start running, and the pillow core is conveyed backward by the first conveying platform 110, so that the pillow core enters the first channel. When the second sensor 112 detects that a pillow core passes through, the controller controls the second conveying platform 120 to start running, and the conveying directions of the opposite surfaces of the first conveying platform 110 and the second conveying platform 120 are the same, that is, the running directions of the belts on the upper surface of the first conveying platform 110 and the lower surface of the second conveying platform 120 are the same, so that the pillow core passes smoothly.

[0055] The pre-compression mechanism 200 includes a movable frame 210, to which a first driving mechanism for driving the movable frame 210 to move laterally is connected. The movable frame 210 is provided with a third conveying platform 220 and a fourth conveying platform 230. The third conveying platform 220 and the fourth conveying platform 230 are symmetrically arranged up and down, and the conveying directions of the opposite surfaces are the same. A second channel for the pillow core to pass laterally is formed between the third conveying platform 220 and the fourth conveying platform 230, which can receive and guide the pillow core conveyed by the conveying mechanism 100, and the second channel extends backward to the outside of the movable frame 210.

[0056] The movable frame 210 is a U-shaped structure with an opening facing upward, including two opposite side panels and a bottom plate to fix the two side panels.

[0057] When the second sensor 112 detects that a pillow core passes through, the controller also controls the first motor to start counterclockwise, driving the first belt 244 to rotate counterclockwise, so that the first belt 244 pulls the movable frame 210 toward the guide conveying mechanism 100, so that the front end of the second channel is connected to the rear end of the first channel, so that the pillow core enters the second channel. Then the controller controls the first motor to start clockwise, and the first belt 244 pulls the movable frame 210 toward the fifth conveying platform 400. Through the operation of the third conveying platform 220 and the fourth conveying platform 230, the pillow core can move backward in the second channel.

[0058] The film bag opening mechanism 300 includes a movable hanging plate 310, which is suspended longitudinally above the frame. A second driving mechanism is connected to the movable hanging plate 310 to drive it to move horizontally. Vertically downward supporting plates 320 are respectively provided at both ends of the movable hanging plate 310 in the longitudinal direction. The upper end of the supporting plate 320 is slidably connected to the movable hanging plate 310, and is connected to a third driving mechanism to drive the two supporting plates 320 to move relative to each other or back to back. At least two supporting rods 330 are fixed on each supporting plate 320, and the multiple supporting rods 330 are arranged up and down and extend backward.

[0059] Each support plate 320 has an upper support rod 331, a middle support rod 332 and a lower support rod 333 arranged in parallel. The upper support rod 331 and the lower support rod 333 are aligned vertically, and the middle support rod 332 protrudes outward from the upper support rod 331 and the lower support rod 333, so that the three support rods 330 on the same side form a triangular layout to prevent the bag from slipping after being opened.

[0060] In addition, the upper support rod 331 and the middle support rod 332 are fixed on a lifting block 334, and the lifting block 334 is connected to a fifth driving mechanism that drives it to move up and down and lock it, and the fifth driving mechanism is connected to the control output end of the controller, and the fifth driving mechanism can use an existing telescopic member such as an electric telescopic rod or a cylinder.

[0061] The second driving mechanism spans above the fifth conveyor platform, and includes a second slide rail 341, a second slider 342, and a second pulley assembly. The second slide rail 341 is transversely fixed to the top of the frame; the second slider 342 is fixed below the movable hanging plate 310, and the second slider 342 is slidably connected to the second slide rail 341; the second pulley assembly includes two second pulleys 343, which are disposed at both ends of the second slide rail 341, and the second pulleys 343 are rotatably fixed to the frame, one of the second pulleys 343 is connected to a second motor that drives it to rotate, and the two second pulleys 343 are connected by a second belt 344, and one side of the second belt 344 is fixed to the movable hanging plate 310. When the second driving mechanism is working, the controller controls the second motor to rotate forward or reverse, so that the second belt 344 can pull the movable hanging plate 310 to move back and forth transversely.

[0062] The third driving mechanism includes a driving screw 351, a limiting rod 352 and two third sliders 353. The driving screw 351 is arranged longitudinally, and its two ends are rotatably fixed to the two ends of the movable hanging plate 310 through bearings. One end of the driving screw 351 is connected to a third motor that drives it to rotate, and the third motor is connected to the control output end of the controller. The threads at the two ends of the driving screw 351 rotate in opposite directions; the limiting rod 352 is arranged parallel to the driving screw 351 and fixed on the movable hanging plate 310; the two third sliders 353 are respectively fixed to the tops of the two supporting plates 320, and the third sliders 353 are threadedly connected to the driving screw 351 and movably penetrate the limiting rod 352. When the third driving mechanism is working, the controller controls the third motor to rotate forward or reverse, so that the two third sliders 353 can drive the two supporting plates 320 to move relatively close or away from each other.

[0063] The fifth conveying platform 400 is disposed longitudinally, and the front end of the fourth conveying platform 230 can be connected to the rear end of the second channel.

[0064] The bag film feeding mechanism 500 is located on the right side of the fifth conveying platform 400, and is arranged opposite to the film bag opening mechanism 300. The bag film feeding mechanism 500 includes a bag film conveying shaft group 510, which is a conventional roll material feeding structure and is not described in detail here. The bag film conveying shaft group 510 can convey the double-layer bag film material horizontally to the fifth conveying platform 400.

[0065] The front end of the bag film conveying shaft group 510 is provided with a material distribution module 520 capable of opening the front end of the double-layer bag film material. The material distribution module 520 includes an upper suction box 521 and a lower suction box 522 arranged relatively up and down. The lower suction box 522 is fixed on the frame. The upper suction box 521 is connected to a sixth driving mechanism that drives it to move up and down and lock it. The sixth driving mechanism is connected to the control output end of the controller. The sixth driving mechanism can use an existing telescopic member such as an electric telescopic rod or a cylinder. The upper suction box 521 and the lower suction box 522 are respectively connected to a negative pressure system, and a plurality of adsorption holes are opened on the upper surface of the upper suction box 521 and the lower surface of the lower suction box 522.

[0066] A cutting module 530 for longitudinally cutting the double-layer bag film is provided in front of the material dividing module 520. The cutting module 530 includes a longitudinal incision on the frame, the length of the incision is greater than the width of the double-layer bag film, and a cutter 531 is slidably provided in the incision. The upper end of the cutter 531 extends upward, and the lower end is connected to an eighth driving mechanism that drives it to move longitudinally and lock it. The eighth driving mechanism is connected to the control output end of the controller, and the eighth driving mechanism can use an existing telescopic member such as an electric telescopic rod or a cylinder. The film material is cut by the cutter 531 to make the fracture smoother.

[0067] A first thermoplastic sealing module 540 capable of sealing the double-layer bag film is disposed in front of the cutting module 530 .

[0068] The sealing mechanism 600 is located behind the fifth conveying platform 400, and includes a compression plate 610 located directly above the fifth conveying platform 400. The compression plate 610 is connected to a fourth driving mechanism that drives it to move up and down. The fifth driving mechanism is connected to the control output end of the controller. The fifth driving mechanism can adopt existing telescopic components such as electric telescopic rods or cylinders. A second thermoplastic sealing module 620 capable of sealing the double-layer bag film is provided on the left side of the fifth conveying platform 400.

[0069] The first thermoplastic sealing module 540 and the second thermoplastic sealing module 620 both include a heating module 541 fixed on a machine tool, and a pressing plate 542 is provided above the heating module 541 . The pressing plate 542 is connected to a seventh driving mechanism for driving the pressing plate 542 to move up and down and lock it.

[0070] The heating module 541 includes a heating tube, a heating block, a thermocouple and a thermostat, and the temperature control is more accurate. The heating block is made of metal, and its top surface is an upward convex angular surface with textures. The pressure plate 542 can match the top surface of the heating block, and there is a receiving groove in the middle of the heating block. The heating tube is placed in the receiving groove and can generate heat after power is turned on. The thermocouple is used to monitor the temperature of the surface of the heating block and transmit the signal to the thermostat. The thermostat has a display screen that can display the actual temperature value of the surface of the heating block fed back by the thermocouple and the set temperature value set for the heating tube. The thermostat adjusts the switch circuit of the heating tube according to the temperature information fed back by the thermocouple to achieve the purpose of controlling the temperature. In order to ensure the accuracy of temperature control and avoid the residual temperature of the heating tube from continuing to rise after the power is turned off, a solid-state relay can be used. When the temperature rises to a temperature close to the set temperature, the solid-state relay controls the current to reduce the temperature between the heating tubes, thereby achieving an ideal temperature control state. When the material dividing module 520 is working, the sixth driving mechanism drives the upper suction box 521 to move downward, clamping the double-layer bag film material between the lower suction box 522 and the upper suction box 521, and then the controller controls the negative pressure system to work, providing negative pressure suction to the upper suction box 521 and the lower suction box 522, and finally the sixth driving mechanism drives the upper suction box 521 to move upward, sucking up the upper film bag, thereby opening the front end of the double-layer bag film material.

[0071] After the front end opening of the double-layer bag film material is opened, the film bag support rod 330 is driven by the second driving mechanism to move toward the material dividing module 520 until the support rods 330 on both sides are inserted into the double-layer bag film material, and then the third driving mechanism controls the support rods 330 on both sides to move away from each other, thereby longitudinally stretching and tightening the double-layer bag film material, and then the second driving mechanism drives the film bag support rod 330 in reverse to reset it, so that it moves toward the pre-compression mechanism 200, and pulls the double-layer bag film material to the top of the fifth conveyor platform.

[0072] Then the controller controls the seventh driving mechanism to drive the upper heating module 541 to move downward, thereby clamping the double-layer bag film between the upper heating module 541 and the lower heating module 541, and using high temperature to heat-melt the two layers of film together. At the same time, the cutting module 530 works to cut the film behind the seal, thereby forming a bag with a rear end seal.

[0073] Driven by the first driving mechanism, the movable frame 210 drives the rear end of the second channel to insert into the bag, and the pillow core is transported into the bag, and the movable frame 210 is reset forward. Then the support rods 330 on both sides approach each other, move forward and exit from the bag, so that the bag containing the pillow core falls on the fifth conveying platform.

[0074] Finally, the fifth conveyor starts to convey the pillow core backward to the bottom of the sealing mechanism 600, and the four-drive mechanism drives the compression plate 610 to move downward to compress the pillow core, and then the second thermoplastic sealing module 620 works to seal the opening at the other end of the bag.

[0075] The pillow core packaging machine uses the bag film feeding mechanism 500 to make rolled film bags into bags with one end sealed and the other end open for packaging pillow cores on one side of the fifth conveying platform 400; and pre-compresses the fluffy pillow core material on the other side of the fifth conveying platform 400 through the pre-compression mechanism 200. The bag opening is opened by the film bag opening mechanism 300 and pulled onto the fifth conveying platform 400, and then the compressed pillow core is fed into the bag to complete the bagging of the pillow core; the bagged pillow core is transported backward on the fifth conveying platform 400, and the other end of the bag is sealed by the sealing mechanism 600, thereby completing the automatic packaging of the pillow core, and the packaged pillow core is transported backward from the fifth conveying platform 400 to the next process.

[0076] When the bag film feeding mechanism 500 is working, the material dividing module 520 opens the front end of the double-layer bag film material, and then the film bag opening mechanism 300 moves backward and inserts into the opening at the front end of the double-layer bag film material and opens it, and then the film bag opening mechanism 300 moves forward and resets, and pulls the double-layer bag film material to the front end of the fifth conveying platform 400, and then the first thermoplastic sealing module 540 works to seal the rear end of the bag, and at the same time the cutting module 530 works to cut off the bag from the double-layer bag film material at the rear to form an independent bag with a sealed rear end.

[0077] The pillow core is conveyed into the system through the guiding conveying mechanism 100, and the pillow core is pre-compressed at the rear end of the first channel so that it can smoothly enter the second channel of the pre-compression mechanism 200. The second channel compresses the pillow core to preliminarily compact the fluffy pillow core, and then the second channel is driven to move backward through the movable frame 210 so that the second channel can extend into the expanded bag, thereby conveying the pillow core into the bag.

[0078] The bagged pillow core is transported backward on the fifth conveying platform 400 to the sealing mechanism 600, and the compression plate 610 is pressed down to further compress the bagged pillow core and expel the air in the bag. At the same time, the second thermoplastic sealing module 620 seals the opening at the other end of the bag, and then the compression plate 610 is moved up and reset to complete the packaging of a pillow core.

[0079] The pillow core packaging machine enables pillow packaging to achieve mechanical automation operation, greatly improving production efficiency and product quality stability and greatly reducing manufacturing and maintenance costs.

[0080] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent substitution made by anyone to the present invention based on the contents of the present invention shall fall within the protection scope of the present invention.
