Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a dual-station synchronous heat sealing and cutting device for the outer packaging of wet wipes. Background Technology

[0002] In the production and processing of wet wipes, in order to ensure the service life of wet wipes, plastic packaging bags are usually used to seal the finished wet wipes. In this process, heat sealing and shearing integrated machines are usually used to complete the corresponding work.

[0003] However, existing devices often have certain problems in actual operation. Due to the influence of the overall working environment, the heat sealing head is in a relatively high temperature state, and the working environment cannot be guaranteed to be absolutely clean and dust-free. Therefore, due to the high temperature effect, after long-term use, dust in the air will accumulate on the surface of the heat sealing head. This will cause problems such as bubbles, air spots or uneven surfaces in the heat sealing area, affecting the packaging quality and effect of the finished product, and may result in ineffective packaging, affecting the overall quality and effect of the work. Summary of the Invention

[0006] In the aforementioned dual-station synchronous heat sealing and cutting device for wet wipe outer packaging, the cleaning mechanism includes a connecting box, two tensioning wheel sets, and a cleaning belt. The two connecting boxes are symmetrically slidably connected to both sides inside the connecting frame, and the two tensioning wheel sets are symmetrically fixedly connected to both sides of one connecting box.

The connecting box has a connecting cavity inside, and the cleaning belt slides through the connecting cavity and the connecting box. The part of the cleaning belt at the top of the connecting box can be used to wipe and clean the bottom of the heat sealing head.

[0007] In the above-mentioned dual-station synchronous heat sealing and shearing device for wet wipe outer packaging, the adhesion mechanism includes two connecting rollers.

The lint-adhesive tape is set on the surface of the connecting roller, and the two ends of the lint-adhesive tape are respectively locked to the two connecting rollers through the locking blocks. The lint-adhesive tape on the surface of one of the connecting rollers is slidably connected to the surface of the cleaning tape.

[0008] In the above-mentioned dual-station synchronous heat sealing and cutting device for wet wipe outer packaging, the linkage mechanism includes two connecting wheels, which are connected by belt drive. Both connecting wheels are rotatably connected to the inside of the connecting box. The inside of the connecting box is locked to a fixing box. The inside of the fixing box is equipped with a motor. The output end of the motor is fixedly connected to one of the connecting wheels through a coupling. The surfaces of the two connecting wheels near the connecting roller are provided with slots. The end of the connecting roller near the connecting wheel is fixedly connected with a clamping head, which is inserted into the slot.

[0009] In the aforementioned dual-station synchronous heat sealing and shearing device for wet wipe outer packaging, the transmission mechanism includes four rotating teeth and four racks. The four rotating teeth are rotatably connected to the inside of the connecting frame, and the four rotating teeth are symmetrically rotatably connected to both sides of the same connecting box. The two sides of the connecting box are symmetrically fixedly connected with toothed plates, which mesh with the bottom of the rotating teeth. The four racks are symmetrically fixedly connected to both sides of the heat sealing head surface, and the racks mesh with one side of the rotating teeth.

Furthermore, the adhesive tape slides into contact with the surface of the cleaning belt, adhering and cleaning any dust remaining on the surface of the cleaning belt after use. This ensures the cleanliness of the cleaning belt itself, further guaranteeing its cleaning effect on the heat sealing head and ensuring overall work quality and effectiveness.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Reference Figures 1-10 A dual-station synchronous heat sealing and cutting device for wet wipe outer packaging includes a conveyor table 1, a conveyor belt 2 fixedly installed on the top of the conveyor table 1, a presser 3 installed on the top of the conveyor table 1, a presser belt 4 rotatably connected to the surface of the presser 3, the presser belt 4 being located above the conveyor belt 2, a connecting frame 5 fixedly connected to the top of the conveyor table 1, an automatic heat sealing head 6 slidably connected inside the connecting frame 5, and also includes; The cleaning mechanism 7 consists of two symmetrical sliding connections on both sides inside the connecting frame 5, with the two cleaning mechanisms 7 always sliding in opposite directions. The cleaning mechanism 7 is used to wipe and clean the heat-sealed part at the bottom of the heat-sealing head 6. The cleaning mechanism 7 includes a connecting box 701, two tensioning wheel sets 702, and a cleaning belt 703. The two connecting boxes 701 are symmetrically sliding connections on both sides inside the connecting frame 5, and the two tensioning wheel sets 702 are symmetrically fixedly connected to both sides of one connecting box 701. The cleaning belt 703 is slidably connected to the connecting box 701 through the two tensioning wheel sets 702. The connecting box 701 has a connecting cavity 11 inside, and the cleaning belt 703 slides through the connecting cavity 11 and the connecting box 701. The part of the cleaning belt 703 located at the top of the connecting box 701 can be used to wipe and clean the bottom of the heat-sealing head 6. A telescopic rod 24 is fixedly connected inside the heat-sealing head 6, and a cutter 25 is slidably connected to the middle of the heat-sealing head 6. The top of the cutter 25 is fixedly connected to the bottom end of the telescopic rod 24.

[0019] The wet wipes and packaging bags, after initial packaging, are conveyed to the bottom of the connecting frame 5 through the progressive conveying effect between the conveyor 1 and the conveyor 3. The heat sealing head 6 descends to heat seal the opening of the packaging bag. At this time, the cutter 25 is driven to move downward by the telescopic rod 24, thereby cutting two adjacent packaging bags. When the two connecting boxes 701 slide close to each other to the bottom of the heat sealing head 6, the tensioning wheel group 702 on both sides of the surface of the same connecting box 701 will drive the cleaning belt 703 to slide along the connecting cavity 11. In this way, the cleaning belt 703 in the sliding state can clean the surface of the heat sealing head 6 after long-term use, preventing a large amount of dust in the air from accumulating and adhering to the surface of the heat sealing head 6.

[0020] An adhesion mechanism 8 is rotatably connected to the interior of the cleaning mechanism 7. The adhesion mechanism 8 is used to clean the cleaning mechanism 7 after use. The adhesion mechanism 8 includes two connecting rollers 801 and a lint-adhesive tape 802. A top spring 12 is fixedly connected inside the connecting roller 801. A locking block 13 is fixedly connected to the other end of the top spring 12. A groove 14 is provided on one side of the surface of the connecting roller 801. The locking block 13 is slidably connected to the groove 14 through the top spring 12. The lint-adhesive tape 802 is disposed on the surface of the connecting roller 801. The two ends of the lint-adhesive tape 802 are respectively locked to the two connecting rollers 801 through the locking block 13. The lint-adhesive tape 802 on the surface of one of the connecting rollers 801 is slidably connected to the surface of the cleaning tape 703.

[0021] The lint-adhesive tape 802 rotates around the two connecting rollers 801 by rotating one of the connecting rollers 801, ensuring that the rotation direction of the lint-adhesive tape 802 is opposite to the sliding direction between the cleaning tape 703. The lint-adhesive tape 802 has a certain adhesive effect, which adsorbs and cleans the dust and other impurities on the surface of the cleaning tape 703, thereby ensuring the cleaning effect of the cleaning tape 703 on the heat-sealing head 6. The top spring 12 pushes the locking block 13 to lock and fix the end of the lint-adhesive tape 802 located inside the groove 14, which can facilitate the replacement of the lint-adhesive tape 802 after use.

[0022] Linkage mechanism 9 is located inside cleaning mechanism 7. Linkage mechanism 9 is used to drive two adhesion mechanisms 8 located inside the same cleaning mechanism 7 to rotate synchronously. Linkage mechanism 9 includes two connecting wheels 901 and motor 902. The two connecting wheels 901 are connected by belt drive. Both connecting wheels 901 are rotatably connected inside connecting box 701. Fixed box 15 is snapped into the inside of connecting box 701. Motor 902 is fixedly connected inside fixed box 15. The output end of motor 902 is fixedly connected to one of the connecting wheels 901 through a coupling. The surface of the two connecting wheels 901 near the connecting roller 801 has a slot 16. A clamping head 17 is fixedly connected to the end of connecting roller 801 near connecting wheel 901. The clamping head 17 is inserted into the slot 16. Two positioning feet 22 are symmetrically fixedly connected to both sides of fixed box 15. Two spring blocks 23 are symmetrically arranged inside connecting box 701 and on the side of fixed box 15. The opposite sides of the two spring blocks 23 are snapped into the two positioning feet 22 respectively.

[0023] The spring block 23 fixes the fixing box 15 inserted into the connecting box 701. At this time, the connecting wheel 901 will be connected to the connecting roller 801 through the insertion effect between the slot 16 and the clamp 17. This ensures that the rotation of the connecting wheel 901 can drive the connecting roller 801 to rotate. At this time, the operation of the motor 902 will drive one of the connecting wheels 901 to rotate. Through the transmission effect of the belt, the two connecting wheels 901 can be ensured to rotate synchronously and in the same direction, ensuring that the connecting wheel 901 can drive the lint-sticking belt 802 to work normally.

[0024] The transmission mechanism 10 is rotatably connected to the inside of the connecting frame 5. The transmission mechanism 10 is used to drive the two cleaning mechanisms 7 to move closer to each other or further away from each other. The transmission mechanism 10 includes four rotating teeth 101 and four racks 102. The four rotating teeth 101 are all rotatably connected to the inside of the connecting frame 5, and the four rotating teeth 101 are symmetrically rotatably connected to both sides of the same connecting box 701. The connecting box 701 is symmetrically fixedly connected to the two sides of the connecting box 701. The racks 102 are symmetrically fixedly connected to both sides of the surface of the heat sealing head 6, and the racks 102 are engaged with one side of the rotating teeth 101.

[0025] When the heat sealing head 6 moves downward to perform heat sealing, the meshing effect between the rack 102 and the rotating tooth 101 drives the rotating tooth 101 to rotate. At this time, the rotation of the rotating tooth 101 drives the connecting box 701 to slide away from the heat sealing head 6 through the toothed plate 18, preventing the connecting box 701 from obstructing the normal operation of the heat sealing head 6. When the heat sealing head 6 moves upward and retracts into the connecting frame 5, the rack 102 drives the rotating tooth 101 to rotate in the opposite direction, thereby driving the two connecting boxes 701 to slide in a direction closer to each other through the toothed plate 18, ensuring that the connecting box 701 can drive the cleaning belt 703 to clean the bottom of the heat sealing head 6 smoothly.

[0026] A pressure plate 19 is slidably connected inside the connecting cavity 11 and above the cleaning belt 703. Two connecting posts 20 are symmetrically fixedly connected to the top of the pressure plate 19. The top of the connecting posts 20 is slidably connected to the inside of the connecting box 701. A compression spring 21 is sleeved on the surface of the connecting posts 20. The other end of the compression spring 21 is fixedly connected to the inside of the connecting cavity 11.

[0027] As the working time increases, the thickness of the lint-sticking tape 802 on the surface of the connecting roller 801 that initially contacts the cleaning tape 703 decreases. At this time, the pressure plate 19 is pushed downward by the compression spring 21, which forces the pressure plate 19 to press the cleaning tape 703, ensuring that the cleaning tape 703 is always in contact with the lint-sticking tape 802 and ensuring the cleaning effect of the lint-sticking tape 802 on the cleaning tape 703.

[0028] The following is a detailed explanation of the specific working principle and usage of the invention: In use, the first step is to transport the finished wet wipes and packaging bags after initial packaging to the bottom of the connecting frame 5 through the progressive conveying effect between the conveyor 1 and the conveyor 3. The heat sealing head 6 descends to heat seal the opening of the packaging bag. At this time, the cutter 25 is driven to move downward through the telescopic rod 24, thereby cutting two adjacent packaging bags. When the two connecting boxes 701 slide close to each other to the bottom of the heat sealing head 6, the tensioning wheel group 702 located on both sides of the surface of the same connecting box 701 will drive the cleaning belt 703 to slide along the connecting cavity 11. In this way, the surface of the heat sealing head 6 after long-term use can be cleaned by the cleaning belt 703 in the sliding state, preventing a large amount of dust in the air from accumulating and adsorbing on the surface of the heat sealing head 6. The second step involves rotating one of the connecting rollers 801 to drive the lint-adhesive tape 802 to rotate around the two connecting rollers 801, ensuring that the rotation direction of the lint-adhesive tape 802 is opposite to the sliding direction between the cleaning tape 703. The lint-adhesive tape 802 has a certain adhesive effect, which adsorbs and cleans the dust and other impurities on the surface of the cleaning tape 703, thereby ensuring the cleaning effect of the cleaning tape 703 on the heat-sealing head 6. The top spring 12 pushes the locking block 13 to lock and fix the end of the lint-adhesive tape 802 located inside the groove 14, which can facilitate the replacement of the lint-adhesive tape 802 after use. The third step involves fixing the fixed box 15 inside the connecting box 701 using the spring block 23. At this time, the connecting wheel 901 will be connected to the connecting roller 801 through the insertion effect between the slot 16 and the clip 17, ensuring a stable connection between the connecting wheel 901 and the connecting roller 801. This ensures that the rotation of the connecting wheel 901 can drive the connecting roller 801 to rotate. At this time, the operation of the motor 902 will drive one of the connecting wheels 901 to rotate. Through the transmission effect of the belt, the two connecting wheels 901 can be ensured to rotate synchronously and in the same direction, ensuring that the connecting wheel 901 can drive the lint-removing tape 802 to work normally.

[0029] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
