[0026] In related art, product packaging equipment integrated with waste recycling equipment introduces plastic pellets into packaging bags. A sensor located at the outlet of the funnel measures the weight of the plastic pellets within the bag. However, the impact of the plastic pellets falling into the bag can affect the accuracy of the sensor's detection.

[0027] Based on this, in order to improve the problems in the related art of inaccurate weight detection by the sensor due to the impact force of plastic particles and the need for multiple people to cooperate in use, the embodiments of the present application provide the following solutions.

[0028] Please also refer to Figures 1 to 3 The embodiment of the present application provides a product packaging device 100 integrated with a waste recycling and reuse device. The product packaging device 100 integrated with the waste recycling and reuse device includes a frame 10, a funnel portion 20, a switch portion 30, and a clamping portion 40, wherein: The funnel part 20 is arranged on the frame 10; the funnel part 20 includes a fixed funnel 21, a connecting part 22, a movable funnel 23 and a first elastic element 24. The connecting part 22 is arranged on the frame 10, and the fixed funnel 21 is arranged on one side of the connecting part 22. The connecting part 22 has a connecting hole 220 and a movable slide 221. The connecting hole 220 is respectively connected to the fixed funnel 21 and the movable funnel 23. The movable slide 221 is located on the side wall of the connecting hole 220. The movable slide 221 is consistent with the direction of the discharge port of the fixed funnel 21. The movable funnel 23 includes a movable funnel body 232 and at least two protrusions 233. The connecting hole 220 is also connected to the movable slide 221. The movable funnel 23 is movably arranged on the other side of the connecting part 22; one end of the first elastic element 24 is connected to the inner side wall of the connecting part 22 away from the fixed funnel 21, and the other end is connected to the side of the movable funnel 23 close to the fixed funnel 21.

[0029] The switch portion 30 is provided on the moving funnel 23 and is used to control the opening size of the feed port of the moving funnel 23. The clamping portion 40 is provided on the moving funnel 23.

[0030] The movable funnel 23 is used to gradually move back to the fixed funnel 21 as the weight of the plastic particles increases, thereby driving the switch part 30 to gradually reduce the opening size of the feed port of the movable funnel 23 .

[0031] It can be understood that the frame 10 is a component for placing components such as the funnel portion 20 and the suturing device 60; for example, the frame 10 can be a metal frame or a metal table.

[0032] The funnel portion 20 is a component for introducing plastic particles into the packaging bag; for example, the funnel portion 20 may include a fixed funnel 21, a connector 22, a movable funnel 23 and a first elastic element 24; for another example, the funnel portion 20 may also be a metal funnel.

[0033] The fixed funnel 21 is used to hold plastic pellets. The connector 22 connects the fixed funnel 21 to the movable funnel 23. The connector 22 can be a metal ring with a connecting hole 220. The movable funnel 23 is used to secure the packaging bag in place with the clamping portion 40; the movable funnel 23 can be a metal funnel.

[0034] The first elastic element 24 is a component used to connect the connecting member 22 and the moving funnel 23; for example, the first elastic element 24 can be a spring or a gas spring.

[0035] The switch portion 30 is a component for controlling the degree of opening of the discharge port of the funnel portion 20; for example, the switch portion 30 includes a linear motor and a valve plate, the linear motor is arranged on the outer wall of the funnel portion 20, and its output end is connected to the valve plate, which controls the degree of opening of the discharge port of the funnel portion 20 by pushing the valve plate; for another example, the switch portion 30 includes a rack 31, a gear 32 and a switch member 33.

[0036] The clamping portion 40 is a component used to fix the packaging bag to the funnel portion 20; for example, the clamping portion 40 can be a robotic arm; for another example, the clamping portion 40 includes a clamping frame 41 and a clamping member 43, which is connected to the funnel portion 20 through the clamping frame 41, and the clamping member 43 is connected to the clamping frame 41, and the packaging bag is clamped by the clamping member 43 and the funnel portion 20 to fix the packaging bag.

[0037] As can be seen from the above, the product packaging device 100 of the integrated waste recycling and reuse equipment provided in the embodiment of the present application, the clamping part 40 is used to fix the packaging bag to the discharge port of the funnel part 20, so that the plastic particles can enter the packaging bag through the funnel part 20. As the packaging bag becomes heavier and under the action of the first elastic element 24, the movable funnel 23 gradually moves back to the fixed funnel 21, thereby driving the switch part 30 to gradually reduce the opening degree of the feed port of the movable funnel 23, thereby making the plastic in the packaging bag less and less, thereby reducing the impact of the impact force of the plastic particles on the weight of the packaging bag, and accurately controlling the weight of the plastic particles in the packaging bag. When the weight of the packaging bag reaches the preset weight, the clamping part 40 releases the fixation of the packaging bag. The above scheme can also complete the above-mentioned precise packaging of plastic particles without the help of multiple sensors and control systems, thereby reducing the production cost of the packaging equipment, and can also make the mechanical structure more stable than the electronic system.

[0038] In some embodiments, please refer to Figures 3 to 5 The connecting member 22 has a connecting hole 220 and at least two movable chutes 221. The connecting hole 220 is connected to the fixed funnel 21. The movable chutes 221 are located on the side wall of the connecting hole 220. The movable chutes 221 are in the same direction as the discharge port of the fixed funnel 21. The movable funnel 23 includes a movable funnel body 232 and at least two protruding members 233, wherein: The movable funnel body 232 is movably disposed in the communicating hole 220 .

[0039] The protrusion 233 is arranged at one end of the movable funnel body 232, and the protrusion 233 is movably arranged in the movable slide groove 221, and the protrusion 233 corresponds one-to-one to the movable slide groove 221; one end of the first elastic element 24 is connected to the inner side wall of the movable slide groove 221 away from the fixed funnel 21, and the other end is connected to the side of the protrusion 233 facing away from the fixed funnel 21.

[0040] It is understood that the movable funnel body 232 is a component for guiding the plastic particles into the packaging bag. The protrusion 233 is a component for cooperating with the first elastic element 24 to gradually lower the packaging bag; for example, the protrusion 233 can be a metal rod or a metal block.

[0041] In this way, by setting the movable funnel 23 as a component consisting of a protrusion 233 and a movable funnel body 232, the protrusion 233 can cooperate with the first elastic element 24 to enable the movable funnel to gradually move back toward the fixed funnel 21, and the protrusion 233 can also prevent plastic particles from entering the space where the first elastic element 24 is located, thereby preventing the movable funnel from getting stuck.

[0042] Optionally, in some embodiments, see Figures 1 to 5 The switch portion 30 includes at least two racks 31, at least two gears 32 and at least two switch members 33, wherein: One end of the rack 31 is connected to the inner wall of the movable chute 221 close to the fixed funnel 21 .

[0043] The gear 32 is rotatably mounted on the protrusion 233 and meshes with the rack 31. One end of the switch 33 is connected to the gear 32. The rack 31, gear 32, switch 33, movable slot 221 and protrusion 233 correspond to each other.

[0044] The movable funnel 23 is used to drive the gear 32 to move back toward the fixed funnel 21 , and the gear 32 is used to rotate forward under the action of the rack 31 , thereby driving the switch member 33 to close the communicating hole 220 .

[0045] It can be understood that the switch member 33 is a component used to control the opening degree of the communication hole 220; for example, the switch member 33 can be a rotary valve or a metal plate.

[0046] With this arrangement, as plastic particles gradually enter the packaging bag and the first elastic element 24, the movable funnel 23 slowly moves away from the fixed funnel 21, thereby driving the gear 32 forward via the rack 31, causing the switch 33 to close the communication hole 220. This solution can reduce the amount of plastic particles entering the packaging bag, thereby reducing the impact force of the plastic particles and thus the impact of the impact force on the packaging bag weight, ultimately ensuring that the packaging bag weight is consistent with the preset mass.

[0047] Optionally, see Figures 1 to 5 The clamping portion 40 includes at least two clamping frames 41, a hydraulic cylinder 42 and at least two clamping members 43, wherein: The clamping frame 41 is disposed on the outer side wall of the moving funnel 23 , and two clamping frames 41 are respectively located on both sides of the moving funnel 23 .

[0048] The hydraulic cylinder 42 is located between the two clamping frames 41 , and one end of the hydraulic cylinder 42 is hinged to one of the clamping frames 41 , and the other end of the hydraulic cylinder 42 is hinged to the other clamping frame 41 .

[0049] The clamping member 43 is provided on the clamping frame 41 , and the clamping member 43 is adapted to the discharge port of the movable funnel 23 . The clamping member 43 corresponds to the clamping frame 41 one by one, and the clamping member 43 is used to fix the packaging bag at the discharge port of the movable funnel 23 .

[0050] It is understood that the clamping frame 41 is a component for mounting the clamping member 43; for example, the clamping frame 41 can be a metal frame or a metal rod. The clamping member 43 is a component for fixing the packaging bag to the moving funnel 23; for example, the clamping member 43 can be a metal sheet or a rubber sheet.

[0051] With this arrangement, the packaging bag is placed between the clamping member 43 and the discharge port of the movable funnel 23. The hydraulic cylinder 42, via the clamping frame 41, adjusts the clamping member 43 to secure the packaging bag. Compared to solutions that use hooks on the outer wall of the movable funnel 23 (which secure the packaging bag to the discharge port of the movable funnel 23), this solution avoids damage to the packaging bag during securement and facilitates automatic release of the packaging bag.

[0052] For example, see Figures 1 to 5 The movable funnel 23 has a first space 230 and two mounting holes 231, the two mounting holes 231 being located on either side of the movable funnel 23. The first space 230 is connected to the external space through one of the mounting holes 231. One of the gears 32 has a connecting space 320. The switch member 33 meshing with the gear 32 having the connecting space 320 has a second space 330. The first space 230 and the second space 330 are connected through the connecting space 320. The switch portion 30 further includes a trigger member 34, a filling medium 35, and a limit member 36, wherein: The trigger member 34 is movably disposed in the mounting hole 231 .

[0053] The filling medium 35 is disposed in the first space 230 , the communicating space 320 , and the second space 330 .

[0054] A portion of the limiting member 36 is disposed on the switch member 33 , and another portion is disposed in the second space 330 .

[0055] The trigger member 34 is used to push the portion of the limiting member 36 located in the second space 330 through the filling medium 35 during the process of clamping the packaging bag, thereby driving the portion of the limiting member 36 located on the switch member 33 to rotate, thereby limiting the rotation of the switch member 33.

[0056] It is understood that the trigger member 34 is a component that is triggered by the clamping member 43; for example, the trigger member 34 may be a plate or a block. The filling medium 35 is a component that fills the mounting hole 231; for example, the filling medium 35 may be a gas or a liquid. The limit member 36 is a component that limits the switch member 33; for example, the limit member 36 includes two plates and a rod, with the plates located at both ends of the rod.

[0057] With this arrangement, the clamping member 43, while securing the packaging bag, pushes the trigger member 34, which in turn pushes the limiting member 36 through the filling medium 35, thereby causing the limiting member 36 to release the restriction on the switch member 33. This arrangement ensures that the communicating hole 220 is open while the clamping member 43 is securing the packaging bag. Furthermore, the clamping member 43 can also partially force the packaging bag into the mounting hole 231, thereby more securely securing the packaging bag at the outlet of the movable funnel 23.

[0058] In some embodiments, see Figure 4 and Figure 5 The switch portion 30 further includes a second elastic element 37 , one end of the second elastic element 37 is disposed on a side of the trigger member 34 facing the inner bottom wall of the mounting hole 231 , and the other end is disposed on the inner bottom wall of the mounting hole 231 .

[0059] It can be understood that the second elastic element 37 is a component for pushing the trigger member 34 to return to its original position; for example, the second elastic element 37 can be a spring or rubber.

[0060] With this arrangement, the second elastic element 37 pushes the trigger member 34 when the clamping member 42 is released from the movable funnel 23, thereby pushing the limiting member 36 through the filling medium 35, thereby causing the limiting member 36 to restrict the switch member 33. This solution ensures that the communication hole 220 is always closed when the clamping member 42 releases the packaging bag.

[0061] Optionally, in some embodiments, see Figures 1 to 5 The product packaging device 100 further includes a transport unit 50, a sewing device 60 and a sewing auxiliary member 70, wherein: The transport portion 50 is disposed on the frame 10 and is located below the clamping portion 40 .

[0062] The sewing device 60 is disposed on the frame 10 and is located above the transport portion 50 .

[0063] The suturing auxiliary member 70 is disposed on the transport portion 50 , and the suturing auxiliary member 70 is located below the suturing device 60 and the clamping portion 40 .

[0064] The transport portion 50 is used to transport the packaging bag to the suturing device 60 when the clamping portion 40 releases the packaging bag, and the suturing auxiliary component 70 is used to suturing the bag opening of the packaging bag.

[0065] It can be understood that the transport part 50 is a component used to transport the packaging bag filled with plastic particles from directly below the funnel part 20 to directly below the suturing device 60; for example, the transport part 50 includes a conveyor belt 51 and a fence 52; for another example, the transport part 50 includes a clamping plate and a linear motor, the linear motor is arranged on the frame 10, and the clamping plate is arranged at the power output end of the linear motor, the bag opening of the packaging bag is clamped by the clamping plate, and the bag opening of the packaging bag is moved to the suturing area of ​​the suturing device 60 by the linear motor.

[0066] The sewing device 60 is a device for sewing packaging bags; for example, the sewing device 60 may be a packaging sewing machine or an automatic sewing machine.

[0067] The sewing auxiliary component 70 is a component used to enable the bag opening of the packaging bag to be closed and enter the sewing area of ​​the sewing device 60; for example, the sewing auxiliary component 70 can be a guide clamp rod or a robot arm.

[0068] With this arrangement, the clamping portion 40 releases its grip on the packaging bag, allowing it to drop smoothly onto the transport portion 50. The suturing aid 70 then allows the packaging bag to enter the suturing area of ​​the suturing device 60. During this process, the suturing aid 70 gradually closes the opening of the packaging bag, allowing the packaging bag to better cooperate with the suturing device 60 and facilitating the suturing process. This solution only requires one worker to replace the packaging bag to complete the entire plastic pellet packaging process, thereby reducing labor costs for plastic pellet packaging.

[0069] Optionally, in some embodiments, see Figure 4 The number of the second elastic elements contained in the mounting hole connected to the first space is less than the number of the second elastic elements contained in the other mounting hole.

[0070] In this way, by arranging different numbers of second elastic elements at both ends, the forces on both ends of the movable funnel are made consistent, and the forces on both sides of the packaging bag are made consistent, so that the packaging bag can be evenly stressed, and finally the damage of the packaging bag is prevented.

[0071] Optionally, see Figures 1 to 5 The transport unit 50 includes a conveyor belt 51 and two fences 52, wherein: The conveyor belt 51 is arranged on the frame 10. Two fences 52 are respectively arranged on both sides of the conveyor belt 51 so that the packaging bags containing plastic particles can move stably along the conveyor belt 51.

[0072] It is understood that the conveyor belt 51 is a device for transporting packaging bags. The fence 52 is a device for stabilizing the packaging bags on the conveyor belt 51; for example, the fence 52 can be a frame or a plate.

[0073] With this arrangement, the packaging bags containing plastic pellets are transported from the funnel portion 20 to the stitching portion of the stitching device 60 by the conveyor belt 51, and the provision of the fence 52 allows the packaging bags to be stably transported to the stitching device 60. Compared to a solution using manual handling, the above solution can both speed up transportation and reduce labor costs.

[0074] The present application also provides a method for using a product packaging device integrated with a waste recycling device, including: Put the plastic granules into the fixed funnel 21 and fix the packaging bag on the movable funnel 23 by the clamping part 40; Open the switch portion 30 to allow the plastic particles to be introduced into the packaging bag through the movable funnel 23; As the plastic particles gradually enter the packaging bag, the movable funnel 23 gradually moves back toward the fixed funnel 21 under the action of the first elastic element 24; As the movable funnel 23 moves back toward the fixed funnel 21 , the switch portion 30 is driven to close the feed port of the movable funnel 23 .

[0075] As can be seen above, the opening degree of the funnel portion 20 is adjusted by controlling the switch portion 30 according to the weight of the packaging bag. As the weight of the packaging bag gradually increases, the opening degree of the funnel portion 20 decreases until the funnel portion 20 is closed. This structure can reduce the impact of the impact force of plastic particles on the weight accuracy of the packaging bag.

[0076] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
