An automatic dental brushing machine and its usage method

Abstract

This invention relates to the field of thread rolling machines, specifically an automatic thread rolling machine, including a base with a movable groove at the center of the top of the base, and a transmission plate inside the movable groove. This automatic thread rolling machine and its method of use consist of a transmission mechanism, a cleaning mechanism, and a pressurizing mechanism. When the moving thread rolling plate moves to the right, the guide wheel slides against the L-shaped support plate into the cleaning groove. When the guide wheel moves to the opening position of the L-shaped guide groove, the return spring elastically recovers and returns the L-shaped support plate to its original position. At this time, the guide wheel is inserted into the interior of the L-shaped guide groove. Then, the guide wheel moves to the left along with the moving thread rolling plate, causing the guide wheel to slide along the inner wall of the L-shaped guide groove and pull the L-shaped support plate towards the moving thread rolling plate, so that the teeth on the trapezoidal cleaning plate are inserted into the side wall of the moving thread rolling plate. As the moving thread rolling plate moves, the teeth scrape away the iron filings remaining in the tooth gaps on the side wall of the moving thread rolling plate, preventing iron filings from adhering to the side wall of the thread rolling plate and improving the thread rolling quality.

Description

Technical Field

[0001] This invention relates to the field of dental floss machines, specifically to an automatic dental floss machine and its usage method. Background Technology

[0002] A thread rolling machine is a device that uses two identical thread rolling surfaces to clamp a screw blank and make it move back and forth to process it into a thread. The thread rolling surfaces have the same tooth profile and helix angle as the screw thread. When the thread rolling plates move back and forth, they roll the screw blank between the two thread rolling plates into a thread.

[0003] An existing patent (publication number: CN112122518A) discloses a screw thread rolling machine, including a machine body, a feeding mechanism for feeding screw blanks, and a thread rolling mechanism for performing thread rolling on the screw blanks fed by the feeding mechanism. In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: 1. When the screw is thread-rolled by two thread rolling plates, a large amount of iron filings are generated on the screw surface during the thread formation process. These iron filings easily adhere to the teeth of the two thread rolling plates, and the accumulated iron filings after multiple thread rolling operations affect the accuracy of the screw thread processing and reduce the thread rolling quality; 2. Typically, a coolant pipe is fixedly installed at the top of the thread rolling machine, and the coolant pipe directionally sprays liquid to cool the position of the thread rolling plates. However, the coolant flowing out of the coolant pipe can only cool the surface of the processed screw, resulting in a single function. Summary of the Invention

[0028] A method for using an automatic teeth-rubbing machine includes the following steps:

[0029] S1. When using this automatic thread rolling machine, the feeder first automatically feeds screws to the fixed thread rolling plate and the moving thread rolling plate. Then, the drive motor is started, which drives the turntable to rotate. The guide pin on the turntable cooperates with the waist-shaped groove on the waist plate, causing the waist plate to move back and forth inside the adjustment groove. At this time, the waist plate carries the drive plate and the moving thread rolling plate to move back and forth inside the movable groove through the L-shaped connecting rod to perform automatic thread rolling processing.

[0030] S2. During the thread rolling process of this equipment, the water pump draws the coolant from the coolant tank to the coolant pipe and sprays it out to cool the screws during the thread rolling process. Since the coolant pipe is fixedly mounted on the transmission plate, when the moving thread rolling plate moves from right to left with the screw to roll the thread, the coolant pipe also moves synchronously with the screw.

[0031] S3. When the moving thread rolling plate moves to the right, the guide wheel slides along the side wall of the L-shaped support plate. When the guide wheel moves to the right end of the L-shaped support plate, it presses against the L-shaped support plate and slides into the cleaning groove. When the guide wheel moves to the opening position of the L-shaped guide groove, the return spring elastically recovers and moves the L-shaped support plate back to its original position. At this time, the guide wheel is inserted into the L-shaped guide groove. Then, the guide wheel moves to the left with the moving thread rolling plate, so that when the guide wheel slides with the L-shaped guide groove, it moves the L-shaped support plate to fit against the moving thread rolling plate. At this time, the teeth on the trapezoidal cleaning plate are inserted into the side wall of the moving thread rolling plate. As the moving thread rolling plate moves, the teeth scrape off the iron filings remaining in the tooth gaps of the side wall of the moving thread rolling plate.

[0032] S4. After the moving thread rolling plate finishes thread rolling the next screw, when the moving thread rolling plate moves to the right, the limiting rod on the right side of the pressure sleeve presses against the side wall of the arc-shaped limiting plate. At this time, the limiting rod is pressed and slides into the pressure sleeve, causing the rack and gear to mesh. Then, the rack and gear ring mesh and rotate clockwise with the pressure ring. With the cooperation of the positioning pin and the arc-shaped groove, the four fan-shaped pressure plates move relative to each other and fit together, making the diameter of the through hole at the bottom of the pressure sleeve smaller. With the liquid flow rate remaining unchanged, the liquid flow velocity increases, causing the coolant to flush the surface of the trapezoidal cleaning plate and the moving thread rolling plate.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In this invention, through the coordinated use of components such as guide wheels, L-shaped support plates, and trapezoidal cleaning plates, when the moving thread rolling plate moves to the right, the guide wheel presses against the L-shaped support plate and slides into the cleaning groove. When the guide wheel moves to the opening position of the L-shaped guide groove, the return spring elastically recovers and moves the L-shaped support plate back to its original position. At this time, the guide wheel is inserted into the interior of the L-shaped guide groove. Then, the guide wheel moves to the left along with the moving thread rolling plate, causing the guide wheel to slide along the inner wall of the L-shaped guide groove and pull the L-shaped support plate to fit against the moving thread rolling plate. This causes the teeth on the trapezoidal cleaning plate to insert into the side wall of the moving thread rolling plate. As the moving thread rolling plate moves, the teeth scrape off the iron filings remaining in the tooth gaps of the side wall of the moving thread rolling plate, preventing iron filings from adhering to the side wall of the thread rolling plate and improving the thread rolling quality.

[0035] In this invention, through the coordinated use of components such as the pressure-boosting sleeve, the fan-shaped pressure-boosting plate, and the arc-shaped limiting plate, when the moving thread-rolling plate moves to the right, the limiting rod on the right side of the pressure-boosting sleeve presses against the side wall of the arc-shaped limiting plate. At this time, the limiting rod is pressed and slides into the pressure-boosting sleeve, causing the rack to mesh with the spur gear. Then, the rack meshes with the gear ring and rotates clockwise with the pressure-boosting ring. With the cooperation of the positioning pin and the arc-shaped groove, the four fan-shaped pressure-boosting plates move relative to each other and fit together, making the diameter of the through hole at the bottom of the pressure-boosting sleeve smaller. At this time, the liquid flow rate increases, allowing the coolant to flush the surface of the trapezoidal cleaning plate and the moving thread-rolling plate. This allows the coolant pipe to have a cooling effect while being flushed by the pressurized coolant, increasing functionality and improving performance.

[0036] In this invention, the coolant pipe, transmission plate and support block are used in combination to make the transmission plate move back and forth, and the coolant pipe moves synchronously with it. This allows the coolant pipe to not only move synchronously with the screw rolling from right to left, but also to uniformly cool the surface of the fixed thread rolling plate, thereby improving the cooling effect. The flushing of the coolant can also reduce the iron filings remaining on the side wall of the fixed thread rolling plate. Attached Figure Description

A pressurizing mechanism 11 is movably connected to the middle of the coolant pipe 10. An arc-shaped limiting plate 12 that cooperates with the pressurizing mechanism 11 is fixedly connected to the middle of the top of the machine base 1. It should be noted that the bottom of the coolant pipe 10 is located between the moving thread rolling plate 4 and the fixed thread rolling plate 16; and the bottom of the coolant pipe 10 is higher than the left end of the feeder 17 to avoid interference.

[0053] A coolant tank 13 is fixedly connected to the top of the base 1, and a water pump 14 is fixedly connected to the top of the coolant tank 13. A telescopic pipe 15 is fixedly connected to one end of the water pump 14, and one end of the telescopic pipe 15 is fixedly connected to one end of the coolant pipe 10. It should be noted that the telescopic pipe 15 ensures that the coolant pipe 10 will not interfere with the movement of the transmission plate 3.

[0054] A fixed thread rolling plate 16, which mates with the movable thread rolling plate 4, is fixedly connected to the top left side of the machine base 1, and a feeder 17 is fixedly connected to the top right side of the machine base 1. It should be noted that a waste collection tank, which mates with the movable groove 2, is provided at the bottom of the machine base 1. The waste collection tank is equipped with a separation screen that can separate solids and liquids. The feeder 17 is an existing device on automatic thread rolling machines. The waste collection tank, the separation screen, and the feeder 17 are all existing technologies and will not be described in detail here.

[0055] In this embodiment, as Figures 1 to 11 As shown, the transmission mechanism 5 includes a mounting groove 501, which is opened on the top of the base 1, and a transmission motor 502 is fixedly connected inside the mounting groove 501.

[0056] The inner wall of the movable groove 2 is provided with an adjustment groove 503 that cooperates with the mounting groove 501. The rotating end of the drive motor 502 extends into the adjustment groove 503 and is fixedly connected to a turntable 504. A guide pin 505 is fixedly connected to the surface of the turntable 504.

[0057] An oblong plate 506 is slidably connected inside the adjusting groove 503. An oblong groove 507 is provided in the middle of one side of the oblong plate 506. A guide pin 505 is slidably connected inside the oblong groove 507.

[0058] On the other side of the waist-shaped plate 506, L-shaped connecting rods 508 are symmetrically fixedly connected, and one end of each of the two L-shaped connecting rods 508 is fixedly connected to the side wall of the transmission plate 3.

[0059] The inner wall of the movable groove 2 is provided with a positioning groove 509. A positioning rod 510 is fixedly connected between the two sides of the inner wall of the positioning groove 509. A positioning block 511 is fixedly connected to the side wall of the transmission plate 3. The middle part of the positioning block 511 is slidably connected to the surface of the positioning rod 510. It should be noted that: the middle part of the positioning block 511 is provided with a round hole, and the positioning block 511 is slidably connected to the surface of the positioning rod 510 through the round hole; the positioning block 511 is located on the left side of the transmission plate 3. When the transmission plate 3 moves to the right to the limit position with the L-shaped connecting rod 508, it ensures that the positioning block 511 can still slide stably on the positioning rod 510, thereby improving stability.

[0060] In this embodiment, as Figures 1 to 11 As shown, guide rods are fixedly connected between the two sides of the inner wall of the adjusting groove 503, and guide blocks are fixedly connected to the top of the waist-shaped plate 506. The inner ring of the guide block is slidably connected to the surface of the guide rods. It should be noted that the cooperation between the guide rods and the guide blocks improves the stability of the waist-shaped plate 506 during its movement.

[0061] In this embodiment, as Figures 1 to 11 As shown, the cleaning mechanism 8 includes a cleaning groove 801, which is formed on the inner wall of the movable groove 2. An L-shaped support plate 802 is slidably connected inside the cleaning groove 801. The side wall of the guide wheel 7 overlaps with one side of the L-shaped support plate 802. Three support rods 803 are fixedly connected at equal intervals on the other side of the L-shaped support plate 802. A return spring 804 is movably sleeved on the side of the support rod 803 near the L-shaped support plate 802. It should be noted that the two ends of the return spring 804 overlap the side wall of the L-shaped support plate 802 and the inner wall of the cleaning groove 801, respectively. The lower part of the bracket 6 is lower than the horizontal line of the bottom of the L-shaped support plate 802. When the guide wheel 7 slides inside the L-shaped guide groove 807, there will be no interference at the bottom of the bracket 6.

[0062] The inner wall of the cleaning groove 801 has three slots 805 equidistantly spaced. One end of each of the three support rods 803 is movably inserted into the three slots 805. An adjusting spring 806 that cooperates with the support rod 803 is movably connected inside the slot 805. It should be noted that a retaining ring is provided at one end of the support rod 803 located in the slot 805, and the adjusting spring 806 is located between the side wall of the retaining ring and the inner wall of the slot 805. When the guide wheel 7 is engaged with one side of the L-shaped support plate 802, both the return spring 804 and the adjusting spring 806 are in an uncompressed state.

[0063] The bottom of the L-shaped support plate 802 is provided with an L-shaped guide groove 807 that mates with the guide wheel 7. A trapezoidal cleaning plate 808 is fixedly connected to the upper part of one side of the L-shaped support plate 802. The side wall of the trapezoidal cleaning plate 808 is provided with teeth 809 that mate with the moving thread rolling plate 4. It should be noted that when the trapezoidal cleaning plate 808 moves toward the moving thread rolling plate 4, the teeth 809 will insert into the tooth gap of the moving thread rolling plate 4. As the moving thread rolling plate 4 moves to the left, the teeth 809 scrape out the iron filings remaining inside the tooth gap of the moving thread rolling plate 4. Furthermore, one side of the trapezoidal cleaning plate 808 is stepped, and the stepped design facilitates the rinsing of the surface by coolant to remove the adhering iron filings.

[0064] In this embodiment, as Figures 1 to 11 As shown, the guide wheel 7 is set at the same horizontal level as the L-shaped guide groove 807. The right side of both the L-shaped support plate 802 and the L-shaped guide groove 807 is set as an inclined surface to cooperate with the guide wheel 7. It should be noted that when the guide wheel 7 moves to the right with the transmission plate 3, the guide wheel 7 will press against the inclined surface on the right side of the L-shaped support plate 802. At this time, the L-shaped support plate 802 slides into the cleaning groove 801, so that the guide wheel 7 enters the opening position of the L-shaped guide groove 807. Then, the return spring 804 moves the L-shaped support plate 802 back to the transmission plate 3. After that, when the transmission plate 3 moves the guide wheel 7 to the left, the guide wheel 7 slides along the inner wall of the L-shaped guide groove 807, so that the guide wheel 7 pulls the trapezoidal cleaning plate 808 on the L-shaped support plate 802 to adhere to the surface of the moving thread rolling plate 4 for cleaning. Finally, after the guide wheel 7 passes out from the left side of the L-shaped guide groove 807, the adjusting spring 806 moves the L-shaped support plate 802 back to the original position.

[0065] In this embodiment, as Figures 1 to 11 As shown, the boosting mechanism 11 includes a boosting sleeve 1101, which is fixedly connected to the middle of the coolant pipe 10. Both ends of the boosting sleeve 1101 are provided with through holes 1102 that cooperate with the coolant pipe 10.

[0066] The inner bottom surface of the pressure booster sleeve 1101 is equidistantly connected with four fan-shaped pressure booster plates 1103, and the top of the fan-shaped pressure booster plates 1103 is fixedly connected with a positioning pin 1104.

[0067] A boosting ring 1105 is movably connected between the tops of the four fan-shaped boosting plates 1103. The surface of the boosting ring 1105 has four arc-shaped grooves 1106 equidistantly spaced along the circumference. Four positioning pins 1104 are slidably connected inside the four arc-shaped grooves 1106 respectively. A toothed ring 1107 is fixedly sleeved on the side wall of the boosting ring 1105.

[0068] A rack 1108 is rotatably connected to the inner bottom surface of the pressure boosting sleeve 1101. The middle part of the rack 1108 meshes with the side wall of the gear ring 1107, and a spur gear 1109 is fixedly sleeved on the top of the rack 1108. It should be noted that a support bearing is fixedly connected between the bottom of the rack 1108 and the inner bottom surface of the pressure boosting sleeve 1101 to improve the stability of the rack 1108's rotation.

[0069] The right side of the pressure booster sleeve 1101 is movably connected to a limiting rod 1110 that mates with the arc-shaped limiting plate 12. A compression spring 1111 is movably sleeved on the right side of the limiting rod 1110. A rack 1112 is fixedly connected to the side wall of the limiting rod 1110, and the side wall of the rack 1112 meshes with the side wall of the spur gear 1109. It should be noted that the trapezoidal cleaning plate 808 is positioned at the bottom of the arc-shaped limiting plate 12. When the limiting rod 1110 presses against the side wall of the arc-shaped limiting plate 12, the liquid sprayed from inside the coolant pipe 10 can wash over the surface of the trapezoidal cleaning plate 808.

[0070] In this embodiment, as Figures 1 to 11 As shown, a rectangular groove is provided on the right side of the pressure booster sleeve 1101, and a limiting rod 1110 is slidably connected inside the rectangular groove. The cross-section of the limiting rod 1110 is rectangular. It should be noted that the rectangular limiting rod 1110 is used to prevent the rotation of the limiting rod 1110 from affecting the meshing of the rack 1112 and the spur gear 1109.

[0071] A guide frame is fixedly connected to the inner top surface of the pressure boosting sleeve 1101. A moving groove is provided in the middle of the guide frame, and the left end of the limiting rod 1110 is slidably connected inside the moving groove. It should be noted that the cooperation between the guide frame and the moving groove improves the stability of the movement of the limiting rod 1110.

[0072] A hemispherical block is fixedly connected to the right end of the limiting rod 1110. One end of the compression spring 1111 rests on the side wall of the hemispherical block, and the other end of the compression spring 1111 rests on the outer wall of the pressure-increasing sleeve 1101. It should be noted that the hemispherical block cooperates with the side wall of the arc-shaped limiting plate 12, so that the limiting rod 1110 can move stably into the pressure-increasing sleeve 1101 after it is pressed against the side wall of the arc-shaped limiting plate 12.

[0073] In this embodiment, as Figures 1 to 11As shown, sliders are symmetrically fixed to the bottom of the fan-shaped booster plates 1103. A groove is provided on the inner bottom surface of the booster sleeve 1101 to cooperate with the slider. The opposite sides of the four fan-shaped booster plates 1103 are all designed with arc-shaped surfaces. It should be noted that, due to the arc-shaped surfaces, when the four fan-shaped booster plates 1103 are fitted together, a conical surface is formed in the middle of the four fan-shaped booster plates 1103, which facilitates the flow of coolant.

[0074] In this embodiment, as Figures 1 to 11 As shown, a method of using an automatic teeth-rubbing machine includes the following steps:

[0075] S1. When using this automatic thread rolling machine, the feeder 17 first automatically feeds screws to the fixed thread rolling plate 16 and the moving thread rolling plate 4. Then, the drive motor 502 is started, which drives the turntable 504 to rotate. The guide pin 505 on the turntable 504 cooperates with the waist groove 507 on the waist plate 506, so that the waist plate 506 moves back and forth inside the adjustment groove 503. At this time, the waist plate 506 carries the drive plate 3 and the moving thread rolling plate 4 to move back and forth inside the movable groove 2 through the L-shaped connecting rod 508 to perform automatic thread rolling.

[0076] S2. During the thread rolling process of this equipment, the water pump 14 draws the coolant inside the coolant tank 13 to the coolant pipe 10 and sprays it out to cool the screw during the thread rolling process. Since the coolant pipe 10 is fixedly installed on the transmission plate 3, when the moving thread rolling plate 4 moves from right to left with the screw to roll the thread, the coolant pipe 10 also moves synchronously with the screw.

[0077] S3. When the moving thread rolling plate 4 moves to the right, the guide wheel 7 slides along the side wall of the L-shaped support plate 802. When the guide wheel 7 moves to the right end of the L-shaped support plate 802, the guide wheel 7 presses against the L-shaped support plate 802 and slides into the cleaning groove 801. When the guide wheel 7 moves to the opening position of the L-shaped guide groove 807, the return spring 804 elastically recovers and moves the L-shaped support plate 802 back to its original position. At this time, the guide wheel 7 is inserted into the interior of the L-shaped guide groove 807. Then, the guide wheel 7 moves to the left with the moving thread rolling plate 4, so that when the guide wheel 7 slides with the L-shaped guide groove 807, it moves the L-shaped support plate 802 to fit against the moving thread rolling plate 4. At this time, the teeth 809 on the trapezoidal cleaning plate 808 are inserted into the side wall of the moving thread rolling plate 4. As the moving thread rolling plate 4 moves, the teeth 809 scrape off the iron filings remaining in the tooth gaps of the side wall of the moving thread rolling plate 4.

[0078] S4. After the moving thread rolling plate 4 performs thread rolling on the next screw, when the moving thread rolling plate 4 moves to the right, the limiting rod 1110 on the right side of the pressure sleeve 1101 presses against the side wall of the arc-shaped limiting plate 12. At this time, the limiting rod 1110 is pressed and slides into the pressure sleeve 1101, so that the rack 1112 meshes with the spur gear 1109. Then the rack 1108 meshes with the gear ring 1107 and rotates the pressure ring 1105 clockwise. With the cooperation of the positioning pin 1104 and the arc-shaped groove 1106, the four fan-shaped pressure plates 1103 move relative to each other and stick together, so that the diameter of the through hole 1102 on the bottom surface of the pressure sleeve 1101 becomes smaller. Under the condition that the liquid flow rate remains unchanged, the liquid flow velocity increases, so that the coolant washes the surface of the trapezoidal cleaning plate 808 and the moving thread rolling plate 4.

[0079] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

8. A method of using an automatic teeth-rubbing machine, comprising the following steps: S1. When using this automatic thread rolling machine, firstly, the feeder (17) automatically feeds screws to the fixed thread rolling plate (16) and the moving thread rolling plate (4). Then, the drive motor (502) is started, so that the drive motor (502) rotates the turntable (504). The guide pin (505) on the turntable (504) cooperates with the waist groove (507) on the waist plate (506), so that the waist plate (506) moves back and forth inside the adjustment groove (503). At this time, the waist plate (506) carries the drive plate (3) and the moving thread rolling plate (4) to move back and forth inside the movable groove (2) through the L-shaped connecting rod (508) to perform automatic thread rolling processing. S2. During the thread rolling process of the automatic thread rolling machine, the water pump (14) draws the coolant inside the coolant tank (13) to the coolant pipe (10) and sprays it out to cool the screw during the thread rolling process. Since the coolant pipe (10) is fixedly set on the transmission plate (3), when the moving thread rolling plate (4) moves from right to left with the screw to roll the thread, the coolant pipe (10) also moves synchronously with the screw. S3. When the moving thread rolling plate (4) moves to the right, the guide wheel (7) slides along the side wall of the L-shaped support plate (802). When the guide wheel (7) moves to the right end of the L-shaped support plate (802), the guide wheel (7) presses against the L-shaped support plate (802) and slides into the cleaning groove (801). When the guide wheel (7) moves to the opening position of the L-shaped guide groove (807), the return spring (804) elastically recovers and returns the L-shaped support plate (802) to its original position. At this time, the guide wheel (7) inserts into the L-shaped guide groove (801). Inside the L-shaped guide groove (807), the guide wheel (7) moves to the left along with the moving thread rolling plate (4), so that when the guide wheel (7) slides with the L-shaped guide groove (807), it brings the L-shaped support plate (802) to fit against the moving thread rolling plate (4). At this time, the teeth (809) on the trapezoidal cleaning plate (808) are inserted into the side wall of the moving thread rolling plate (4). As the moving thread rolling plate (4) moves, the teeth (809) scrape off the iron filings remaining in the tooth gaps of the side wall of the moving thread rolling plate (4). S4. After the moving thread rolling plate (4) performs thread rolling on the next screw, when the moving thread rolling plate (4) moves to the right, the limiting rod (1110) on the right side of the pressure sleeve (1101) presses against the side wall of the arc-shaped limiting plate (12). At this time, the limiting rod (1110) is pressed and slides into the pressure sleeve (1101), so that the rack (1112) meshes with the spur gear (1109), and then the rack (1108) meshes with the gear ring (1107). With the booster ring (1105) rotating clockwise, the four fan-shaped booster plates (1103) move relative to each other and fit together under the cooperation of the positioning pin (1104) and the arc groove (1106), making the diameter of the through hole (1102) on the bottom surface of the booster sleeve (1101) smaller. With the liquid flow rate unchanged, the liquid flow rate increases, so that the coolant washes the surface of the trapezoidal cleaning plate (808) and the moving thread rolling plate (4).
