[0033] In an embodiment of the present utility model, as Figures 1 to 3 shown, there is provided a dental floss holder automatic production machine, which includes a wire feeding device 100, an injection molding device 200, and a wire ironing and punching device 300 arranged side by side in sequence. The wire feeding device 100 is used to feed the wire to the injection mold passing through the injection molding device 200. The injection molding device 200 is used to inject molten plastic onto the wire in the injection mold to form a dental floss holder. The wire ironing and punching device 300 includes a frame 310, a punching mechanism 320, a wire ironing mechanism 330, and a translation and handling mechanism 340. The frame 310 is arranged beside the injection molding device 200. The punching mechanism 320 and the wire ironing mechanism 330 are arranged vertically on the frame 310. The translation and handling mechanism 340 is installed between the punching mechanism 320 and the wire ironing mechanism 330. The translation and handling mechanism 340 is used to transport the dental floss holder that has completed injection molding in the injection mold of the injection molding device 200 between the punching mechanism 320 and the wire ironing mechanism 330. After the punching mechanism 320 punches the water inlet of the dental floss holder and the wire ironing mechanism 330 irons the wire of the dental floss holder, the dental floss holder is then transported to the dental floss holder material receiving position.

[0034] In the dental floss holder automatic production machine provided by the embodiment of the present utility model, the wire is unwound and conveyed to the injection mold passing through the injection device 200 by the wire unwinding device 100, and then the injection device 200 injects molten plastic into the injection mold to form a dental floss holder with the wire attached. After that, the injection mold is opened, and the translation and handling mechanism 340 of the wire ironing and punching device 300 removes the batch of injection-completed dental floss holders from the opened injection mold to between the punching mechanism 320 and the wire ironing mechanism 330. Then, the punching mechanism 320 is started to punch the sprue of the dental floss holder. After that, the wire connecting every two dental floss holders is ironed and cut by the wire ironing mechanism 330 to form each independent dental floss holder. Finally, the dental floss holder is transported to the dental floss holder receiving position for receiving by the translation and handling mechanism 340, realizing automatic operation throughout the process and having high production efficiency.

[0035] In an embodiment of the present utility model, as Figures 4 to 5 shown, the translation and handling mechanism 340 includes a vacuum suction plate 341, a translation plate 342, a handling cylinder 343, a handling lead screw module 344, and two gantry support frames 345. The two gantry support frames 345 are installed on the frame 310 at intervals. The translation plate 342 is mounted on the two gantry support frames 345. The handling lead screw module 344 is installed on the gantry support frames 345 and is used to drive the translation plate 342 to move along the direction of the gantry support frames 345. The handling cylinder 343 is installed on the translation plate 342 and its piston rod passes downward through the space between the two gantry support frames 345. The vacuum suction plate 341 is connected to the piston rod of the handling cylinder 343 and extends beyond the orthographic projection of the translation plate 342. Driven by the handling lead screw module 344, the vacuum suction plate 341 can be translated into the injection mold of the injection device 200. Specifically, the setting of the two gantry support frames 345 forms an operating space. Driven by the handling lead screw module 344, the translation plate 342 can be driven to translate between the two gantry support frames 345. The translation plate 342 drives the vacuum suction plate 341 to move. And because the vacuum suction plate 341 extends beyond the orthographic projection of the translation plate 342, in this way, when the translation plate 342 moves close to the injection device 200, the connected vacuum suction plate 341 can extend into the injection mold of the injection device 200. Then, the vacuum suction plate 341 is driven by the handling cylinder 343 to move up and down to suck the injection-molded dental floss holders in the injection mold of the injection device 200. Then, the vacuum suction plate 341 is driven by the handling lead screw module to transport the dental floss holders to the punching mechanism 320 and the wire ironing mechanism 330 respectively to perform the operations of punching the sprue and wire ironing. After completing the operations of punching the sprue and wire ironing, the handling lead screw module 344 finally transports the dental floss holders to the receiving station.

[0036] It should be noted that the vacuum suction plate 341 can achieve vacuum suction of dental floss rod products through an externally connected vacuum generator. The vacuum generator is an external device and belongs to the prior art, so it will not be elaborated here.

[0037] In an embodiment of the present invention, as Figures 2 to 5 shown, the translation and handling mechanism 340 further includes guide shafts 346 and bushings 347. A plurality of the bushings 347 are installed on the translation plate 342, and a plurality of guide shafts 346 respectively passing through the bushings 347 are installed on the vacuum suction plate 341. The corresponding guide shafts 346 are in sliding fit with the corresponding bushings 347. Specifically, through the mutual cooperation of the bushings 347 and the guide shafts 346, the lifting movement of the vacuum suction plate 341 driven by the handling cylinder 343 is stable and precise.

[0038] In an embodiment of the present invention, as Figures 2 to 5 shown, the handling lead screw module 344 includes a motor 3441, a lead screw nut assembly 3442, a slide rail assembly 3443, and a connecting block 3444. The lead screw nut group and the slide rail assembly 3443 are both installed on the gantry support frame 345. The motor 3441 is drivingly connected to the lead screw nut assembly 3442. The translation plate 342 is mounted and fixed on the slider of the slide rail assembly 3443, and the connecting block 3444 is connected and fixed between the lead screw nut assembly 3442 and the translation plate 342. Specifically, the motor 3441 drives the lead screw nut assembly 3442 to move linearly, so as to drive the translation plate 342 to translate along the guide of the slide rail assembly 3443 through the connecting block 3444. In this way, the reciprocating translation movement of the vacuum suction plate 341 between the two gantry support frames 345 can be controlled to perform operations at multiple workstations.

[0039] In an embodiment of the present invention, as Figures 2 to 3As shown in Figure 6, the punching mechanism 320 includes a punching bracket 321, a cutting plate 322, a cutting cylinder 323 and a plurality of punching knives 324. The punching bracket 321 is installed on the frame 310, the cutting cylinder 323 is installed on the punching bracket 321 and its piston rod is set downward, the cutting plate 322 is located above the vacuum suction plate 341 and is connected to the piston rod of the cutting cylinder 323, and each of the punching knives 324 is installed on the cutting plate 322 and is used to punch the water outlet of the dental floss stick adsorbed by the vacuum suction plate 341. Specifically, the cutter cylinder 323 installed on the punching bracket 321 drives the cutter plate 322 connected thereto to move up and down, thereby driving the multiple punching knives 324 on the cutter plate 322 to move up and down, so that when there is a dental floss stick adsorbed by the vacuum suction plate 341 below the punching knife 324, the water outlet on the dental floss stick can be punched out by moving the punching knife 324 downward. The vacuum suction plate 341 is provided with a space hole for the punching knife 324 to move, so as to ensure that the punching knife 324 can move downward until the punching knife 324 adsorbs the dental floss stick.

[0040] In one embodiment of the present invention, Figures 2 to 3 As shown in FIG. 7 , the ironing mechanism 330 includes an ironing cylinder 331, an ironing rod plate 332, and a plurality of ironing rods 333. The ironing cylinder 331 is mounted on the frame 310 and is located between the two gantry support frames 345, and its piston rod is arranged upward. The ironing rod plate 332 is connected to the piston rod of the ironing cylinder 331. Each of the ironing rods 333 is mounted on the ironing rod plate 332. The ironing rods 333 generate heat after being powered on, so that they can be used to iron the wires connected between each two dental floss sticks adsorbed by the vacuum suction plate 341. Specifically, the ironing rods 333 can generate heat after being connected to an external power source, and the heating requirement can be controlled according to an external PLC controller. When the ironing cylinder 331 drives the ironing rod plate 332 to rise, it can also drive the ironing rods 333 on the ironing rod plate 332 to rise. Since the ironing rods 333 generate heat, when they touch the wire between two dental floss sticks, they can cut the wire, thereby producing each independent dental floss stick. Each independent dental floss stick is also adsorbed by the vacuum suction plate 341 at this time, and then transported to the material receiving station under the action of the transport screw module 344 to realize automated operation.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
