[0053] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0054] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein.

A guiding and conveying mechanism 100, a pre-compression mechanism 200, a film bag stretching mechanism 300, a fifth conveying platform 400, a bag film feeding mechanism 500 and a sealing mechanism 600 are sequentially arranged on the frame.

[0056] In the pillow core packaging machine, multiple independently operating conveying platforms are provided.

The rear end of the second conveying platform 120 slopes downward, and a first channel for the pillow core to pass horizontally is formed between the first conveying platform 110 and the second conveying platform 120. Vertical mounting plates are fixed on both sides of the first conveying platform 110, and a plurality of vertically arranged mounting holes are provided on the mounting plates. The second conveying platform 120 is detachably mounted in any of the mounting holes by bolts. By fixing the second conveying platform 120 in the 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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. By adjusting the height of the lifting block 334, the height of the bag can be adjusted to match different models of pillow cores.

[0065] The second driving mechanism is disposed across the upper side of the fifth conveying platform and includes a second slide rail 341, a second slider 342, and a second pulley assembly. The second slide rail 341 is horizontally fixed to the top of the machine frame; the second slider 342 is fixed to the lower side of the moving 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 respectively disposed at both ends of the second slide rail 341, and the second pulleys 343 are rotatably fixed to the machine frame.

A second belt 344 is drivingly connected between the two second pulleys 343, and one side of the second belt 344 is fixed to the moving hanging plate 310. When the second driving mechanism is working, the controller controls the second motor to rotate forward or backward, so as to realize the reciprocating lateral movement of the second belt 344 pulling the moving hanging plate 310.

[0066] The third driving mechanism includes a driving screw 351, a limiting rod 352, and two third sliders 353. The driving screw 351 is longitudinally arranged, and its two ends are rotatably fixed to the two ends of the moving hanging plate 310 through bearings. One end of the driving screw 351 is connected to a third motor that drives its rotation, and the third motor is connected to the control output end of the controller. The thread directions at both ends of the driving screw 351 are opposite; the limiting rod 352 is arranged parallel to the driving screw 351 and is fixed to the moving hanging plate 310; the two third sliders 353 are respectively fixed to the tops of the two support plates 320, and the third sliders 353 are threadedly connected to the driving screw 351 and movably penetrate through the limiting rod 352. When the third driving mechanism is working, the controller controls the third motor to rotate forward or backward, so as to realize the relative approach or separation of the two support plates 320 driven by the two third sliders 353.

[0067] The fifth conveying platform 400 is longitudinally arranged, and the front end of the fifth conveying platform 400 can be connected to the rear end of the second channel.

[0068] The bag film feeding mechanism 500 is located on the right side of the fifth conveying platform 400 and is disposed opposite to the film bag expanding mechanism 300. The bag film feeding mechanism 500 includes a bag film conveying shaft group 510, and the bag film conveying shaft group 510 is a conventional coil feeding structure, which will not be elaborated here. The bag film conveying shaft group 510 can horizontally convey the double-layer bag film material to the fifth conveying platform 400.

[0069] At the front end of the bag film conveying shaft group 510, there is a material separating module 520 capable of opening the front end of the double-layer bag film material. The material separating module 520 includes an upper suction box 521 and a lower suction box 522 arranged oppositely up and down. The lower suction box 522 is fixed to the machine frame. The upper suction box 521 is connected with a sixth driving mechanism for driving its up and down movement and locking. The sixth driving mechanism is connected to the control output end of the controller. The sixth driving mechanism can adopt existing telescopic components such as electric telescopic rods or cylinders. The upper suction box 521 and the lower suction box 522 are respectively connected with 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.

[0070] In front of the material separating module 520, there is a cutting module 530 for longitudinally cutting the double-layer bag film material. The cutting module 530 includes a cutting opening longitudinally opened on the machine frame. The length of the cutting opening is greater than the width of the double-layer bag film material. A cutting knife 531 is slidably arranged in the cutting opening. The upper end of the cutting knife 531 extends upward, and the lower end is connected with an eighth driving mechanism for driving its longitudinal movement and locking. The eighth driving mechanism is connected to the control output end of the controller. The eighth driving mechanism can adopt existing telescopic components such as electric telescopic rods or cylinders. By cutting the film material with the cutting knife 531, the cut is made smoother.

[0071] In front of the cutting module 530, there is a first thermoplastic sealing module 540 capable of sealing the double-layer bag film.

[0072] The sealing mechanism 600 is located behind the conveyance of 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 with a fourth driving mechanism for driving its up and down movement. 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. On the left side of the fifth conveying platform 400, there is a second thermoplastic sealing module 620 capable of sealing the double-layer bag film.

[0073] Both the first thermoplastic sealing module 540 and the second thermoplastic sealing module 620 include a heating module 541 fixed to the machine tool. Above the heating module 541, there is a pressing plate 542. The pressing plate 542 is connected with a seventh driving mechanism for driving its up and down movement and locking.

[0074] The heating module 541 includes a heating tube, a heating block, a thermocouple and a temperature controller, enabling more precise temperature control. The heating block is made of metal, with its top surface being a convex angular surface with patterns. The pressing plate 542 can be in concave-convex fit with the top surface of the heating block. 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 being powered on. The thermocouple is used to monitor the temperature of the surface of the heating block and transmit the signal to the temperature controller. The temperature controller has a display screen, which can display the actual temperature value of the surface of the heating block feedback by the thermocouple and the set temperature value set for the heating tube. The temperature controller adjusts the switching circuit of the heating tube according to the temperature information feedback by the thermocouple to achieve the purpose of temperature control. To ensure the accuracy of temperature control and avoid the residual temperature of the heating tube from continuing to rise after power-off, a solid-state relay can be used. When the temperature is about to approach the set temperature, the solid-state relay controls the magnitude of the current to reduce the temperature between the heating tubes, thereby achieving an ideal temperature control state.

[0075] When the material distribution module 520 works, 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. Then the controller controls the negative pressure system to work, providing negative pressure suction for the upper suction box 521 and the lower suction box 522. Finally, the sixth driving mechanism drives the upper suction box 521 to move upward, sucking up the upper layer of the film bag, so that the front end opening of the double-layer bag film material opens.

[0076] After the front end opening of the double-layer bag film material opens, the film bag support rod 330 moves towards the material distribution module 520 under the drive of the second driving mechanism until the support rods 330 on both sides are inserted into the double-layer bag film material. 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. The second driving mechanism then drives the film bag support rod 330 to reset in the reverse direction, making it move towards the pre-compression mechanism 200 and pulling the double-layer bag film material above the fifth conveyor table.

[0077] 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 material between the upper heating module 541 and the lower heating module 541, and melting and adhering the two layers of film materials together using high temperature. At the same time, the cutting module 530 works, cutting the film material behind the seal, thereby forming a bag with a sealed back end.

[0078] Under the drive of the first driving mechanism, the movable frame 210 drives the rear end of the second channel to insert into the bag, conveying the pillow core into the bag, and the movable frame 210 resets forward. Then the support rods 330 on both sides approach each other and move forward to withdraw from the bag, making the bag containing the pillow core fall on the fifth conveyor table.

[0079] Finally, the fifth conveying platform starts, conveys the pillow core backward to the lower part of the sealing mechanism 600, 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 operates to seal the opening at the other end of the bag.

[0080] On one side of the fifth conveying platform 400 of this pillow core packaging machine, the roll film bag feeding mechanism 500 makes a roll of film bags into individual bags for packaging the pillow core, with one end sealed and the other end open; on the other side of the fifth conveying platform 400, the pre-compression mechanism 200 pre-compresses the fluffy pillow core material. The bag opening expanding mechanism 300 expands the opening of the bag and drags it onto the fifth conveying platform 400, and then the compressed pillow core is sent into the bag to complete the bagging of the pillow core; the bagged pillow core is conveyed backward on the fifth conveying platform 400, and the sealing mechanism 600 seals the other end of the bag, thus completing the automatic packaging of the pillow core. The packaged pillow core is conveyed backward by the fifth conveying platform 400 to the next process.

[0081] When the roll film bag feeding mechanism 500 is working, the material distribution module 520 makes the front end of the double-layer film bag material open, then the bag opening expanding mechanism 300 moves backward and inserts into the opening at the front end of the double-layer film bag material and expands it, then the bag opening expanding mechanism 300 moves forward and resets, drags the double-layer film bag material to the front end of the fifth conveying platform 400, and then the first thermoplastic sealing module 540 operates to seal the rear end of the bag. At the same time, the material cutting module 530 operates to cut off the bag from the rear double-layer film bag material, forming an independent bag with the rear end sealed.

[0082] The pillow core conveying mechanism 100 conveys the pillow core material into the system and pre-compresses the pillow core 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 and initially compacts the fluffy pillow core. Then the movable frame 210 drives the second channel to move backward so that the second channel can extend into the expanded bag, thereby conveying the pillow core into the bag.

[0083] The bagged pillow core is conveyed backward on the fifth conveying platform 400 to the sealing mechanism 600. The compression plate 610 presses down to further compress the bagged pillow core, expelling 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 moves up and resets to complete the packaging of one pillow core.

[0084] This pillow core packaging machine enables the mechanical automation of pillow packaging, greatly improving the production efficiency and the stability of product quality, and significantly reducing the manufacturing cost and maintenance cost.

[0085] The above are only the preferred embodiments of the present utility model, and any simple modifications, deformations and equivalent replacements made to the present utility model by anyone according to the content of the present utility model shall fall within the protection scope of the present utility model.
