Description

Technical Field

[0001] The invention relates to the technical field of dental floss sticks, and in particular to a dental floss stick production line capable of automatically dividing materials. Background Art

[0002] As people's health awareness improves, the market for personal oral care products is expanding. Among them, dental floss sticks, as one of the effective tools for cleaning the gaps between teeth, are favored by more and more consumers. Dental floss sticks, also known as floss sticks or floss picks, are an oral cleaning product that complements toothbrushes. They can effectively remove food debris and plaque in the gaps between teeth, prevent dental diseases, and maintain oral health. Compared with traditional dental floss, dental floss sticks are easier to carry and simple to operate, showing higher practicality and convenience in the fast-paced modern life.

[0003] However, the production process of dental floss sticks, especially the packaging process, still faces many challenges. The dental floss stick packaging machines widely used in the market mainly rely on thermoforming technology, which completes the packaging process by dropping the dental floss sticks into a plastic film and then hot-melting the plastic film to seal it. Although this packaging method can ensure a certain degree of sealing and aesthetics, it also has obvious shortcomings. First, when the packaging material is exhausted, it is basically necessary to manually replace the new plastic film every time, and then manually connect the new plastic film to the previous roll of plastic film. Manual connection of the plastic film is not only time-consuming and labor-intensive, but also reduces production efficiency. Secondly, for those unqualified dental floss sticks caused by production defects, existing equipment often lacks an effective detection and rejection mechanism, resulting in defective products entering the market, thereby affecting the overall quality level and brand image of the product. Summary of the invention

[0004] In view of this, the present invention provides a dental floss pick production line that can automatically sort materials, which can solve the shortcomings of the existing dental floss pick production line, such as the lack of an effective detection and rejection mechanism, which leads to the influx of defective products into the market, and when the packaging material is exhausted, it is necessary to manually connect the new plastic film with the previous roll of plastic film, which is not only time-consuming and labor-intensive, but also inefficient.

[0034] When in use, three rolls with packaging bags 101 wound on them are put on the expansion shaft 7, and then the expansion shaft 7 is controlled to fix the rolls by expansion, and then the servo motor II 603 drives the rotating plate 602 and the expansion shaft 7 and the rubber column 606 thereon to rotate until the rubber column 606 on one of the expansion shafts 7 contacts the friction wheel 605, and then the servo motor III 604 drives the friction wheel 605 to rotate, so that the friction wheel 605 uses the friction force to drive the contacting rubber column 606 and the expansion shaft 7 to rotate, thereby driving the roll on the corresponding expansion shaft 7 to unwind the packaging bag 101, and then the servo motor III 604 drives the friction wheel 605 to rotate, and then the servo motor III 604 drives the friction wheel 605 to rotate, and then the servo motor III 604 drives the rubber column 606 and the expansion shaft 7 to rotate, and then drives the roll on the corresponding expansion shaft 7 to unwind the packaging bag 101, and then the servo motor III 604 drives the friction wheel 605 to rotate, and then drives the servo motor III 604 ... The operator pulls the head end of the packaging bag 101 downward to pass between the electric suction cup 8 and the hot melter II 11, and then continues to pull the head end of the packaging bag 101 downward to pass into the limiting mold frame 301, so that the limiting mold frame 301 squeezes the packaging bag 101 with a straight cross section into a U-shaped cross section, and then passes the packaging bag 101 with a U-shaped cross section between two electric rollers II 12, the visual inspection module 13, between two hot melters I 303, and between two electric rollers I 304 in sequence, and makes the packaging bag 101 with a U-shaped cross section contact with the electric roller II 12 and the electric roller I 304 (such as Figure 2 As shown), the friction wheel 605 is then driven to stop rotating by the servo motor III 604, so that the reel on the corresponding expansion shaft 7 stops unwinding the packaging bag 101, and then the two hot melters I303 are driven to approach by the electric push rod I302, so that the two hot melters I303 perform hot-melt sealing on the packaging bag 101 with a U-shaped cross section, and then the two hot melters I303 are driven to move away by the electric push rod I302; then, a sleeve with an inner diameter larger than the diameter of the screw rod 503 is used to thread multiple dental floss sticks, so that multiple dental floss sticks are sleeved on the sleeve, and then the sleeve is sleeved into a dental floss stick that is not hung The tooth floss stick is placed on the screw rod 503, and the hand is gently grasped on the sleeve to block the dental floss stick, and then the sleeve is pulled out from the screw rod 503 until the sleeve is completely away from the screw rod 503, and the dental floss stick on the sleeve will be blocked by the hand and remain on the screw rod 503. In this way, multiple dental floss sticks can be hung on the screw rod 503 to complete the loading, and then the above operation is repeated until all the screw rods 503 are hung with dental floss sticks, and then the electric rotating platform 501 drives the rotating platform to drive the servo motor I 502 and the screw rod 503 to rotate until one of the screw rods 503 is located directly above the material guide platform 504; Then, the corresponding servo motor I 502 drives the main body of the screw rod 503 to rotate, so that the main body of the screw rod 503 conveys a dental floss stick hung on it to the guide platform 504, so that the guide platform 504 conveys the dental floss stick into the packaging bag 101 with a U-shaped cross section, thereby realizing automatic loading of the dental floss stick, and at the same time controlling the electric roller II 12 to rotate intermittently. When the dental floss stick falls down in the packaging bag 101 and passes through the electric roller II 12, the electric roller II 12 will convey the dental floss stick slowly. The dental floss stick passes through the visual inspection module 13 slowly, thereby reducing the falling speed of the dental floss stick in the packaging bag 101, so that the visual inspection module 13 has enough time to inspect the dental floss stick and then determine whether the dental floss stick is a good product: if the dental floss stick is determined to be a good product after inspection by the visual inspection module 13, no additional operation is required, so that the good dental floss stick falls down to the top of the last hot-melt package in the packaging bag 101; if the dental floss stick is determined to be a defective product after inspection by the visual inspection module 13, the visual inspection module 13 will send a signal. After receiving the signal, the controller 2 controls the electric push rod IV 1602 to drive the connecting plate 1603 and the magnetic block I 1604 to move forward, so that the magnetic block I 1604 uses magnetic attraction to drive the magnetic plate 1601 and the guide plate 15 to move forward, so that the guide plate 15 enters the packaging bag 101 with a U-shaped cross section. Then, when the defective dental floss stick falls down to the top surface of the guide plate 15, the guide plate 15 will guide the defective dental floss stick out of the packaging bag 101 with a U-shaped cross section, so as to remove the defective dental floss stick. The good and bad dental floss sticks are automatically separated, and then the controller 2 controls the electric push rod IV 1602 to drive the connecting plate 1603 and the magnetic block I 1604 to move backward and reset, so that the magnetic block I 1604 drives the magnetic plate 1601 and the guide plate 15 to move backward and reset by magnetic attraction, so that the guide plate 15 leaves the packaging bag 101 with a U-shaped cross section, and then the controller 2 controls the corresponding servo motor I 502 to drive the corresponding screw rod 503 body to rotate, so as to refill the dental floss stick;When a good dental floss stick falls on the last hot-melt seal of the packaging bag 101, the electric push rod Ⅰ302 drives the two hot melters Ⅰ303 to approach again, so that the two hot melters Ⅰ303 perform hot-melt seal on the packaging bag 101 with a U-shaped cross section, thereby packaging the dental floss sticks inside. Then, the electric push rod Ⅰ302 drives the two hot melters Ⅰ303 to move away from each other, and the servo motor Ⅲ604 drives the friction wheel 605 to rotate, so that the reel on the corresponding expansion shaft 7 unwinds the packaging bag 101, and controls the electric roller Ⅰ304 to rotate, so that the electric roller I304 conveys the hot-melt sealed packaging bag 101 downward to between the stop block 401 and the cutting knife 403, and then drives the cutting knife 403 to move leftward through the electric push rod II402, so that the cutting knife 403 presses the hot-melt sealed packaging bag 101 on the stop block 401, and the cutting knife 403 cuts the hot-melt sealed packaging bag 101, so that the hot-melt sealed packaging bag 101 falls downward into the discharging frame 404 for discharging, so that the packaged dental floss stick is discharged through the discharging frame 404, and then the above operation is repeated to repeatedly package the dental floss stick; When the roll of packaging bag 101 being used is used up, the tail end of the roll of packaging bag 101 will be separated from the roll. At this time, the tail end of the roll of packaging bag 101 will fall down due to gravity. Therefore, the distance between the roll of packaging bag 101 and the distance sensor 9 will gradually change. When the distance sensor 9 senses that the distance between the roll of packaging bag 101 is greater than the preset value, the distance sensor 9 sends a signal. After receiving the signal, the controller 2 will control the electric suction cup 8 to suck the roll of packaging bag 101, and then drive the rotating plate 602 and the expansion shaft 7 and rubber column 606 thereon to rotate again through the servo motor II 603 until the rubber column 606 on the next expansion shaft 7 contacts the friction wheel 605, and then drive the friction wheel 605 to rotate again through the servo motor III 604, so that the friction wheel 605 uses the friction force to drive the contacting rubber column 606 and the expansion shaft 7 to rotate, thereby driving the roll on the corresponding expansion shaft 7 to suck the packaging bag 101. The two rolls of packaging bags 101 are unwound. When the head end of the packaging bag 101 is flush with the packaging bag 101 sucked on the electric suction cup 8, the electric push rod III10 drives the hot melt device II11 to move forward, so that the hot melt device II11 hot-melts the two rolls of packaging bags 101, thereby automatically connecting the two rolls of packaging bags 101. Subsequently, the hot melt device II11 is driven by the electric push rod III10 to move backward and reset, and then the electric suction cup 8 is controlled to release the packaging bag 101, and then the packaging work of the dental floss stick can be continued (the packaging bag 101 that uses this connecting position as a package needs to be picked out and discarded later to avoid affecting the overall packaging quality due to individual items). When continuing to pack the dental floss stick, the expansion shaft 7 can be controlled to contract to loosen the empty reel, and then the empty reel can be removed and replaced with a new roll of packaging bag 101, and then the expansion shaft 7 can be controlled to expand and fix the new roll of packaging bag 101. In this way, the packaging work of the dental floss stick can be continued when the reel of the packaging bag 101 is replaced without affecting the packaging work of the dental floss stick.

[0035] See also Figure 8 As shown, a collecting frame 17 is also included; the collecting frame 17 is connected to the lower rear portion of the limiting mold frame 301, the collecting frame 17 is located directly below the guide plate 15, and the collecting frame 17 is used to collect bad dental floss sticks.

[0036] By providing the collection frame 17, the bad dental floss sticks guided by the guide plate 15 can fall into the collection frame 17 for collection, thereby facilitating the operator to subsequently process the bad dental floss sticks in a centralized manner.

[0037] See also Fig.10 As shown, a fixing nut 18 is also included; a thread is provided at the right end of the expansion shaft 7, and a fixing nut 18 is threadedly installed on the thread provided on the expansion shaft 7, and the fixing nut 18 is used to limit the roll with the packaging bag 101 wound around the expansion shaft 7.

[0038] By setting the fixing nut 18, when it is necessary to put the reel with the packaging bag 101 wound around it on the expansion shaft 7, the fixing nut 18 can be unscrewed first, and then the reel with the packaging bag 101 wound around it can be put on the expansion shaft 7, and then the fixing nut 18 can be twisted back again. In this way, the fixing nut 18 can be used to limit the reel with the packaging bag 101 wound around it on the expansion shaft 7 to prevent the reel from being disengaged due to offset on the expansion shaft 7; when it is necessary to remove the empty reel from the expansion shaft 7, the fixing nut 18 is first unscrewed, and then the empty reel can be removed from the expansion shaft 7, and then after replacing a new roll of packaging bag 101, the fixing nut 18 can be twisted back again.

[0039] See also Fig.10 As shown, a U-shaped limiting plate 19 is also included. The electric suction cup 8 is connected with the U-shaped limiting plate 19. The U-shaped limiting plate 19 is used to limit the packaging bag 101 so that the packaging bag 101 can be close to the electric suction cup 8.

[0040] By setting a U-shaped limiting plate 19, when the operator pulls the head end of the packaging bag 101 downward to pass between the electric suction cup 8 and the hot melter II 11, the operator can instead pull the head end of the packaging bag 101 downward to pass through the U-shaped limiting plate 19. In this way, the packaging bag 101 is limited by the U-shaped limiting plate 19, which can make the packaging bag 101 closer to the electric suction cup 8 so that the electric suction cup 8 can adsorb the packaging bag 101 more stably.

[0041] See also Fig.11 As shown, a protective mechanism is also included, which includes a connecting block 20, a fixed cover 21 and a rotating cover 22; the connecting block 20 is connected to the right rear side of the middle of the connecting frame I 601, and the connecting block 20 is located behind the electric push rod III 10; the bottom of the connecting block 20 is connected to the fixed cover 21; the rotating cover 22 is rotatably connected to the fixed cover 21, and the fixed cover 21 and the rotating cover 22 both cover the screw rod 503, so as to protect the dental floss sticks on the screw rod 503, and the fixed cover 21 and the rotating cover 22 are made of transparent material, so that the operator can view the number of dental floss sticks on the screw rod 503 through the fixed cover 21 and the rotating cover 22.

[0042] See also Fig.11 As shown, a fixing mechanism is also included, which includes a magnetic block II 23 and a magnetic block III 24; the magnetic block II 23 is connected to the rear side of the connecting block 20; the magnetic block III 24 is connected to the top of the rotating cover 22, and when the rotating cover 22 is rotated and unfolded, the magnetic block III 24 on the rotating cover 22 will contact the magnetic block II 23, and at this time, the magnetic block II 23 and the magnetic block III 24 will fix the rotating cover 22 by magnetic attraction.

[0043] When multiple dental floss sticks need to be hung on the screw rod 503 for loading, the rotating cover 22 is first pulled to rotate and unfold, so that the magnetic block III 24 on the rotating cover 22 contacts the magnetic block II 23, so that the magnetic block II 23 and the magnetic block III 24 fix the rotating cover 22 by magnetic attraction, and then the multiple dental floss sticks can be hung on the screw rod 503 for loading, and the screw rod 503 covered by the fixed cover 21 can be driven by the electric rotating table 501 to rotate and adjust its position, so that the screw rod 503 covered by the fixed cover 21 can be rotated and moved to the bottom of the rotating cover 22, and then the multiple dental floss sticks can be hung on After the material is loaded on the screw rod 503, the rotating cover 22 is pushed to reverse and reset, so that the magnetic block III 24 on the rotating cover 22 is separated from the magnetic block II 23, so that the fixed cover 21 and the rotating cover 22 protect the dental floss sticks on the screw rod 503 to prevent the surrounding people, objects and air flow from causing shaking of the dental floss sticks on the screw rod 503. The fixed cover 21 and the rotating cover 22 are both made of transparent material, which can facilitate the operator to view the number of dental floss sticks on the screw rod 503 through the fixed cover 21 and the rotating cover 22, thereby facilitating the operator to replenish the dental floss sticks on the screw rod 503 in time.
