Description

Technical Field

[0001] This utility model relates to the technical field of sealing and trimming integrated machines, and in particular to a sealing and trimming integrated machine for plastic bags. Background Technology

[0002] The integrated sealing and cutting machine for plastic bags mainly achieves simultaneous sealing and cutting operations through the integrated design of heat sealing and cutting functions, synchronous motion control, and a dedicated actuator. The sealing principle uses electric heating elements (such as nickel-chromium alloy heating strips or ceramic heating plates) or ultrasonic vibration to melt and bond the material in the sealing area of ​​the plastic bag (heat sealing method), or achieves welding through high-frequency vibration molecular friction heat generation (ultrasonic sealing). The cutting principle is to cut the edge of the bag opening with a hot cutting knife while sealing. The typical cutting structure is an upper and lower mold structure. The upper mold integrates the heating sealing strip and the hot cutting knife, and the lower mold is a support pad (with groove positioning). The hot cutting knife generally uses a thin alloy blade with built-in heating wire.

[0003] In existing technologies, when using a sealing and trimming machine to seal and trim plastic bags, it is difficult for the machine to cut the plastic bag completely. The main reasons include: improper temperature control (insufficient, uneven, or excessive), poor blade condition (wear, poor flatness, unsuitable pressure), material characteristics (differences in material or thickness, different melting points of composite films), insufficient equipment maintenance (parts wear, sensor failure), and improper adjustment of operating parameters (not adapted to the material, environmental influences). As a result, the edges may stick to the bag body, requiring manual tearing of the plastic bag edges to stop the heat sealing. When the plastic bag is long or the heat sealing and cutting workload is large, the operation becomes quite troublesome. Therefore, it is necessary to propose a plastic bag sealing and trimming machine to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated machine for sealing and trimming plastic bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastic bag sealing and edge-cutting integrated machine includes a heat-sealing and edge-cutting machine body. A controller is fixedly installed on the top surface of the heat-sealing and edge-cutting machine body. It also includes a pulling component disposed on the top surface of the heat-sealing and edge-cutting machine body for pulling the edge of the plastic bag. The pulling component includes a movable plate disposed on the top surface of the heat-sealing and edge-cutting machine body. Two first circular through holes are formed on one side of the movable plate. A support frame is movably sleeved on the inner circular wall of the first circular through holes. A spring is movably sleeved on the outer circular wall of the support frame. The bottom surface of the support frame is fixedly installed to the top surface of the heat-sealing and edge-cutting machine body. One end of the support frame is fixedly installed to one side of the sealing lower mold of the heat-sealing and edge-cutting machine body. The moving plate has a support column and a rotating clamp plate fixedly installed inside. A connecting hole is opened on one side of the rotating clamp plate, and the connecting hole is movably sleeved with the support column. Two torsion springs are movably sleeved on the outer circular wall of the support column. The movable end of the torsion spring is fixedly installed with the rotating clamp plate, and the fixed end of the torsion spring is fixedly installed with one side of the moving plate. A first fixing plate is fixedly installed on the bottom surface of the rotating clamp plate, and a steel wire rope is fixedly installed on one side of the first fixing plate. A guide wheel frame is fixedly installed on the top surface and one side of the heat sealing and trimming machine body. A separation pedal is hinged to one side of the heat sealing and trimming machine body. The separation pedal is fixedly installed with the steel wire rope, and the steel wire rope rests on the rotating wheel of the guide wheel frame.

[0007] As a further embodiment of this utility model, a third fixing plate is fixedly installed on the top surface of the support leg of the heat sealing and trimming machine body, and a tension spring is fixedly installed on one side of the third fixing plate. The tension spring is fixedly installed on the top surface of the separation pedal.

[0008] As a further embodiment of this utility model, the top surface of the heat sealing and trimming machine body is provided with a first fixing hole and a third fixing hole, and the top surface of the moving plate is provided with a second fixing hole.

[0009] As a further embodiment of this utility model, a plurality of toothed grooves are provided on one side of the rotating clamping plate, and a fixing groove is provided on the top surface of the moving plate.

[0010] As a further embodiment of this utility model, a guide hopper is fixedly installed on the inner top surface of the heat sealing and trimming machine body, and a second fixing plate is fixedly sleeved inside the support leg of the heat sealing and trimming machine body, with a collection bin provided on the top surface of the second fixing plate.

[0011] As a further embodiment of this utility model, a limiting tube frame is fixedly installed on one side of the guide wheel frame at the bottom, and the steel wire rope passes through the interior of the limiting tube frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By using the heat-sealing and edge-cutting machine body, controller, first fixing hole, moving plate, support frame and spring in coordination, the plastic bag can be pulled to break. When the heat cutting is insufficient, there is no need to manually pull off the stuck edge of the plastic bag. Just step on the separation pedal to complete the breaking effect. When the length of the plastic bag is long, or when the heat-sealing and cutting workload is large, there is no need to frequently tear the bag. The broken plastic bag will enter the collection chamber for collection, or be manually removed at regular intervals, which is convenient and practical.

[0014] 2. The collection bin collects the plastic bags that fall into the guide hopper through the first fixed hole. The limiting tube frame limits the steel wire rope to prevent it from slipping off the outside of the guide wheel frame. The toothed grooves increase the friction between the rotating clamp and the plastic bag, ensuring the "biting" effect on the plastic bag. Attached Figure Description

[0027] Reference Figures 1-8A plastic bag sealing and edge-cutting integrated machine includes a heat-sealing and edge-cutting machine body 1, model number RIOUFKJ. A controller 2 is fixedly installed on the top surface of the heat-sealing and edge-cutting machine body 1. The machine also includes a pulling component, which is located on the top surface of the heat-sealing and edge-cutting machine body 1 and is used to pull the edge of the plastic bag. The pulling component includes a moving plate 4, which is located on the top surface of the heat-sealing and edge-cutting machine body 1. Two first circular through holes are opened on one side of the moving plate 4. A support frame 5 is movably sleeved on the inner circular wall of the first circular through holes, and a spring 6 is movably sleeved on the outer circular wall of the support frame 5. The bottom surface of the support frame 5 is fixedly installed to the top surface of the heat-sealing and edge-cutting machine body 1, and one end of the support frame 5 is fixedly installed to one side of the sealing lower mold of the heat-sealing and edge-cutting machine body 1. The movable plate 4 has a support column 11 and a rotating clamping plate 7 fixedly installed inside. A connecting hole 12 is opened on one side of the rotating clamping plate 7. The connecting hole 12 is movably connected to the support column 11. Two torsion springs 8 are movably connected to the outer circular wall of the support column 11. The movable end of the torsion spring 8 is fixedly installed to the rotating clamping plate 7. The fixed end of the torsion spring 8 is fixedly installed to one side of the interior of the movable plate 4. A first fixing plate 15 is fixedly installed on the bottom surface of the rotating clamping plate 7. A steel wire rope 10 is fixedly installed on one side of the first fixing plate 15. A guide wheel frame 14 is fixedly installed on the top surface and one side of the interior of the heat sealing and trimming machine body 1. A separation pedal 13 is hinged to one side of the interior of the heat sealing and trimming machine body 1. The separation pedal 13 is fixedly installed to the steel wire rope 10. The steel wire rope 10 rests on the rotating wheel of the guide wheel frame 14.

[0028] In use, the user steps on the separation pedal 13 with their other foot, causing the rotation to pull the tension spring 20 and the steel wire rope 10. The two guide wheel frames 14 support the steel wire rope 10, causing it to pull the first fixed plate 15. This, supported by the support column 11, causes the torsion spring 8 to rotate and compress. Simultaneously, several toothed grooves 16 on one side of the rotating clamp 7 press down on the edge of the plastic bag and push it into the fixing groove 9, thus "biting" the edge of the plastic bag. At this point, continuing to step on the pedal causes the steel wire rope 10 to continue pulling the first fixed plate 15, but the rotating clamp 7, already in the biting state, can no longer rotate. Consequently, the first fixed plate 1... 5. Moving the movable plate 4 backward compresses the spring 6, thereby pulling the bitten plastic bag and breaking it at the hot cut. Then, the sealing pedal and the separating pedal 13 are released, and the plastic bag is removed. The separating pedal 13 is reset under the pull of the tension spring 20, and the movable plate 4 is reset under the push of the spring 6. The rotating clamp 7 is reset and opened under the torque of the torsion spring 8, so that the edge of the "bitten" plastic bag can be removed. At this time, there is no obstruction from the upper and lower molds, which facilitates the operation. Alternatively, the sealing operation can continue, so that the plastic bag falls into the guide hopper 17 through the first fixing hole 3 and enters the collection bin 19.

[0029] In this embodiment, a third fixing plate 21 is fixedly installed on the top surface of the support leg of the heat sealing and trimming machine body 1. A tension spring 20 is fixedly installed on one side of the third fixing plate 21, and the tension spring 20 is fixedly installed on the top surface of the separation pedal 13. A first fixing hole 3 and a third fixing hole 23 are opened on the top surface of the heat sealing and trimming machine body 1, and a second fixing hole 22 is opened on the top surface of the moving plate 4. A plurality of toothed grooves 16 are opened on one side of the rotating clamping plate 7, and a fixing groove 9 is opened on the top surface of the moving plate 4. A guide hopper 17 is fixedly installed on the top surface inside the heat sealing and trimming machine body 1, and a second fixing plate 18 is fixedly sleeved inside the support leg of the heat sealing and trimming machine body 1. A collection bin 19 is provided on the top surface of the second fixing plate 18. A limiting tube frame 24 is fixedly installed on one side of the guide wheel frame 14 located at the bottom, and a steel wire rope 10 passes through the interior of the limiting tube frame 24.

[0030] In use, to allow the edge of the plastic bag to extend into the opening formed by the rotating clamping plate 7 and the moving plate 4, a rectangular groove can be opened on one side of the upper and lower molds of the heat sealing and cutting machine body 1 (provided that it does not interfere with the heat sealing and heat cutting). This allows the moving plate 4 to enter the rectangular groove, enabling the rotating clamping plate 7 and the moving plate 4 to clamp more of the plastic bag edge. At the same time, a fan or air blowing device can be installed on the top of the rotating clamping plate 7 and fixed to the sides of the moving plate 4 or other positions, such as a pulse nozzle, by a bracket. The plastic bag pulled down is blown away by air blowing, eliminating the need for manual cleaning. The collection chamber 19 is used to collect the plastic bags that fall into the guide hopper 17 through the first fixing hole 3. The limiting tube frame 24 is used to limit the steel wire rope 10 to prevent the steel wire rope 10 from slipping off the outside of the guide wheel frame 14. The toothed grooves 16 increase the friction between the rotating clamping plate 7 and the plastic bag, ensuring the "biting" effect on the plastic bag.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0032] When the user needs to use the heat sealing and cutting machine body 1 to seal and cut plastic bags, the user sits in front of the heat sealing and cutting machine body 1, places the plastic bag on the top surface of the heat sealing and cutting machine body 1 above the sealing lower mold, and positions it. At the same time, the edge of the plastic bag extends into the opening formed by the rotating clamping plate 7 and the moving plate 4. Then, the user steps on the sealing (left) pedal of the heat sealing and cutting machine body 1, causing the sealing and cutting frame to rotate downward to heat and seal the plastic bag. At the same time, the hot cutting head heats and cuts the sealing edge.

[0033] At this point, the user steps on the separation pedal 13 with their other foot, causing the tension spring 20 and steel wire rope 10 to rotate and pull. The two guide wheel frames 14 support the steel wire rope 10, causing it to pull the first fixed plate 15. Under the support of the support column 11, the steel wire rope 10 rotates and compresses the torsion spring 8. Simultaneously, several toothed grooves 16 on one side of the rotating clamp 7 press down on the edge of the plastic bag and push the plastic bag into the fixed groove 9, thus "biting" the edge of the plastic bag. If the pedal is pressed again, the steel wire rope 10 continues to pull the first fixed plate 15, but the rotating clamp 7, which is in the biting state, can no longer rotate. The first fixed plate 15 then drives the moving plate 4 to move backward and compress the spring 6. The moving plate 4 then pulls the bitten plastic bag, causing the hot-cut section to break. After that, the sealing pedal and separation pedal 1 are released. 3. Remove the plastic bag. The separating pedal 13 resets under the pull of the tension spring 20, the moving plate 4 resets under the push of the spring 6, and the rotating clamp 7 resets and opens under the torque of the torsion spring 8. The "bitten" edge of the plastic bag can then be removed, or the sealing operation can continue. The plastic bag will fall into the guide hopper 17 through the first fixing hole 3 and enter the collection chamber 19, thus achieving the effect of pulling the plastic bag to break it. When the heat cutting is insufficient, there is no need to manually pull off the stuck edge of the plastic bag. Simply stepping on the separating pedal 13 will achieve the effect of breaking it. When the length of the plastic bag is long, or when the heat sealing and cutting workload is large, there is no need to frequently tear the bag. The broken plastic bag will enter the collection chamber 19 for collection, or it can be manually removed at regular intervals. This is convenient and practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
