[0002] In the prior art, when treating patients with maxillofacial fractures, it is necessary to reposition the displaced fracture site, and then use titanium plates and steel nails to fix the fracture site. The titanium plates that can be used in the operation include straight titanium plates, curved titanium plates, L-shaped titanium plates and special-shaped titanium plates, among which L-shaped titanium plates and special-shaped titanium plates usually do not need to be cut, and the amount used is small. Straight titanium plates and curved titanium plates are more commonly used.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0030] Embodiment 1 of the present invention: Figure 1-Figure 6 As shown, a titanium plate electric cutting device includes a box body, which includes a bottom plate 6, a left side wall 7, a right side wall 8, a top cover 9, a front side wall 1 and a rear side wall 32. A first knife block mounting hole 2 is opened in the horizontal direction on the front side wall 1 of the box body, and a first cutting knife block 3 is plugged and slidably connected with the first knife block mounting hole 2. A knife block driving device is arranged in the box body, and a titanium plate blocking plate 4 is arranged on the outer wall of the front side wall 1. A first discharge hole 5 is opened on the titanium plate blocking plate 4, and the first discharge hole 5 is opposite to the first knife block mounting hole 2.

[0031] Specifically, the bottom plate 6 is a rectangular plate, the left side wall 7 is arranged opposite to the right side wall 8, the lower end of the left side wall 7 is fixedly connected to the left side surface of the bottom plate 6, the lower end of the right side wall 8 is fixedly connected to the right side surface of the bottom plate 6, the front side wall 1 and the rear side wall 32 are arranged opposite to each other, the lower end of the front side wall 1 is fixedly connected to the front side surface on the bottom plate 6, and the lower end of the rear side wall 32 is fixedly connected to the rear side surface of the bottom plate 6; the top cover 9 is detachably connected to the top of the front side wall 1, the rear side wall 32, the left side wall 7 and the right side wall 8, for example, by a snap connection or a bolt connection.

[0032] The top cover 9 is designed as a detachable structure to facilitate maintenance and inspection of the blade block drive device. In the non-working state, the end of the first cutting blade block 3 is located inside the first blade block mounting hole 2. When working, the blade block drive device pushes the first cutting blade block 3 to move, and the end of the first cutting blade block 3 extends out of the first blade block mounting hole 2 and cooperates with the titanium plate blocking plate 4 to cut the titanium plate 33.

[0033] Furthermore, the top and bottom surfaces of the first cutting blade block 3 are both planes, the left and right surfaces of the first cutting blade block 3 are both inwardly concave arc surfaces, and one end of the first cutting blade block 3 located in the box body is fixedly provided with a vertically arranged connecting plate 10, and a side of the connecting plate 10 away from the front side wall 1 is fixedly provided with a roller mounting seat 11, and a roller 12 is rotatably mounted on the roller mounting seat 11, and the roller 12 is horizontally arranged.

[0034] It should be noted that the front side wall 1 is relatively thick, and the thickness of the front side wall 1 is preferably greater than one-half of the length of the first cutting blade block 3, and less than two-thirds of the length of the first cutting blade block 3. By controlling the thickness of the front side wall 1, the first blade block mounting hole 2 can not only guide the first cutting blade block 3, but also support the first cutting blade block 3, so that the first cutting blade block 3 is not easily broken. It should be understood by those skilled in the art that controlling the thickness of the front side wall 1 to support the first cutting blade block 3 is only a preferred embodiment, and the support of the first cutting blade block 3 can also be achieved by setting a support plate on the inner wall of the front side wall 1. The scheme of setting a support plate is a conventional means in the prior art, and the support plate can be set by conventional means. The scheme of setting a support plate is not shown in the drawings of this application.

[0035] In this embodiment, the first cutting blade block 3 is used to cut the linear titanium plate, and the left side and the right side of the first cutting blade block 3 are designed to be inwardly concave arc surfaces, so that after the titanium plate 33 is cut by the first cutting blade block 3, the cutting position forms an arc surface, which solves the right angle problem of the flat-nose pliers cutting position in the prior art. The arc-shaped cutting surface will not cause damage to the soft tissue around the titanium plate installation position.

[0036] In this embodiment, the cross-sectional shape of the first blade block mounting hole 2 and the cross-sectional shape of the first material discharge hole 5 are the same as the cross-sectional shape of the first cutting blade block 3, and have the same size.

[0037] A first mounting post 13 is fixedly provided on the side of the connecting plate 10 facing the front side wall 1, a second mounting post 14 is fixedly provided on the inner wall of the front side wall 1, a first spring 15 is provided between the connecting plate 10 and the front side wall 1, one end of the first spring 15 is sleeved on the first mounting post 13, and the other end of the first spring 15 is sleeved on the second mounting post 14.

[0038] The first spring 15 provides thrust to the connecting plate 10 so that the roller 12 always keeps in contact with the blade drive device. The first spring 15 also serves to return the first cutting blade 3 to its original position.

[0039] Furthermore, the blade drive device includes a cam 16, a ring gear 17, a driving gear 18 and a stepper motor 19. A cam mounting bracket 20 is fixedly provided on the base plate 6. The rotating shaft of the cam 16 is mounted on the cam mounting bracket 20 through a bearing. The ring gear 17 is fixedly provided on one side of the cam 16. The roller 12 is rollingly connected to the cam 16. The axis of the cam 16 and the axis of the roller 12 are located at the same height, and the axis of the cam 16 is parallel to the axis of the roller 12. The stepper motor 19 is fixedly provided on the base plate 6 through a motor base 21. The driving gear 18 is fixedly provided on the output shaft of the stepper motor 19. The driving gear 18 is meshed with the ring gear 17. The outer diameter of the driving gear 18 is smaller than the outer diameter of the ring gear 17.

[0040] The outer diameter of the driving gear 18 is smaller than the outer diameter of the gear ring 17. This combination is used to achieve the effect of reducing speed and increasing torque. Under the action of the cam 16, the first cutting blade 3 has sufficient force to cut the titanium plate 33. It should be noted that the specific values ​​of the outer diameter of the driving gear 18 and the outer diameter of the gear ring 17 can be designed by those skilled in the art according to actual needs. The design method is a prior art. This embodiment does not limit the specific values ​​of the outer diameter of the driving gear 18 and the outer diameter of the gear ring 17.

[0041] A controller 39 is provided in the box body, and a switch 34 is provided on the top cover 9. The switch 34 and the stepper motor 19 are electrically connected to the controller 39. The controller 39 can adopt a PLC programmable controller. The controller 39 is an existing product and can be purchased directly. The working principle of the controller 39 is not elaborated in this embodiment.

[0042] Furthermore, a cover shell 25 is provided on the side of the titanium plate blocking plate 4 away from the front side wall 1 , the lower end of the cover shell 25 is an open structure, and a waste collection box 26 is provided below the titanium plate blocking plate 4 .

[0043] The titanium plate blocking plate 4 is arranged in the vertical direction, and the upper and lower ends of the titanium plate blocking plate 4 both have horizontal connection parts. The titanium plate blocking plate 4 is fixedly connected to the front side wall 1 through the horizontal connection parts of the upper and lower ends, and the spacing between the titanium plate blocking plate 4 and the front side wall 1 is equal to the thickness of the titanium plate 33. When the first cutting blade block 3 cuts off the titanium plate 33, the cut waste 40 enters the first discharge hole 5. When the end of the first cutting blade block 3 enters the first discharge hole 5, the waste 40 falls into the cover shell 25 and falls along the cover shell 25, and falls into the collection box 26 from the bottom of the cover shell 25.

[0044] The function of the cover 25 is to prevent the waste material 40 from flying out, so that the waste material 40 can smoothly fall into the collection box 26 to reduce waste.

[0045] A first titanium plate positioning block 27 and a first titanium plate support plate 28 are fixedly provided on the outer wall of the front side wall 1. The top surface of the first titanium plate positioning block 27 is flush with the lower edge of the first knife block mounting hole 2. The first titanium plate support plate 28 is a horizontal plate. One end of the first titanium plate support plate 28 is fixedly connected to one end of the first titanium plate positioning block 27. The first titanium plate support plate 28 has a first side baffle 29.

[0046] The top surface of the first titanium plate positioning block 27 is a profiled surface, the middle of which is a plane, and the two sides of the plane are symmetrical arc surfaces, which are used to limit the two circular ring parts on the linear titanium plate so that the connected part between the two circular ring parts is aligned with the first cutting knife block 3.

[0047] Working principle: When the straight titanium plate 33 needs to be cut, the titanium plate 33 is taken out and the position to be cut is determined according to the requirements. For the sake of convenience, it is assumed that the titanium plate 33 needs to be cut between the third and fourth annular portions. Then, the third and fourth annular portions are clamped on the first titanium plate positioning block 27 (please refer to Figure 5 ), at this time, the lower left part of the third circular ring part from right to left contacts the right arc surface of the first titanium plate positioning block 27, the lower right part of the fourth circular ring part contacts the left arc surface of the first titanium plate positioning block 27, and the fourth to eighth circular ring parts are all in contact with the first titanium plate support plate 28. At this time, under the restriction of the first side baffle plate 29 and the titanium plate blocking plate 4, the titanium plate 33 is close to the front side wall 1.

[0048] Press the switch 34, and the controller 39 controls the stepper motor 19 to rotate a preset number of times. The number of times the stepper motor 19 rotates can make the cam 16 rotate exactly one circle. When the stepper motor 19 rotates, the gear ring 17 is driven to rotate by the driving gear 18, and the gear ring 17 drives the cam 16 to rotate together. One rotation of the cam 16 is a working cycle. When the cam 16 rotates, the roller 12 also rotates under the action of friction. At the same time, when the cam 16 rotates, it will also apply a thrust to the roller 12 to make the roller 12 rotate while moving horizontally toward the front side wall 1. At the same time, the roller mounting seat 11, the connecting plate 10 and the first cutting knife block 3 move horizontally together, and the end of the first cutting knife block 3 extends out of the first knife block mounting hole 2. Since the titanium plate 33 is limited by the titanium plate blocking plate 4, the end of the first cutting knife block 3 can cut off the connection between the third annular portion and the fourth annular portion, and the cut waste 40 enters the first discharge hole 5. The first cutting knife 3 continues to move until it enters the first discharge hole 5. The cam 16 stops moving inside, which is the maximum position at which the cam 16 can push the first cutting knife 3 to move. After the waste 40 is pushed out of the first discharge hole 5, it falls along the cover shell 25 and falls into the waste collecting box 26 from the bottom of the cover shell 25. The cam 16 continues to rotate. At this time, the cam 16 no longer applies thrust to the roller 12. At this time, under the elastic force of the first spring 15, the roller mounting seat 11, the connecting plate 10 and the first cutting knife block 3 move in the opposite direction together. When the cam 16 rotates one circle, the end of the first cutting knife block 3 returns to the first knife block mounting hole 2. At this time, a working cycle is ended. If the titanium plate 33 needs to be cut again, the switch 34 needs to be pressed again.

[0049] Embodiment 2 of the present invention, please combine Figure 2 and Figure 6 On the basis of the first embodiment, two sensor brackets 36 are further provided on the bottom plate 6 in the present embodiment. The two sensor brackets 36 are located on both sides of the cam 16. A group of opposing infrared sensors 37 are provided on the two sensor brackets 36. A through hole 38 is provided on the cam 16. When the end surface of the first cutting blade block 3 is flush with the outer wall of the front side wall 1, the infrared rays emitted by the opposing infrared sensor 37 can pass through the through hole 38. The opposing infrared sensor 37 is also electrically connected to the controller 39.

[0050] It should be noted that, assuming that the stepper motor 19 fails, causing the stepper motor 19 to continue rotating after rotating the preset number of circles, if no other measures are taken, the equipment cannot automatically stop running, and the first cutting blade block 3 will continue to reciprocate until it is manually closed. However, the present embodiment is provided with a beam-type infrared sensor 37. When the switch 34 is pressed, the infrared rays emitted by the transmitting end of the beam-type infrared sensor 37 can pass through the through hole 38. The receiving end receives the infrared rays and sends a signal to the controller 39. At this time, the controller 39 determines that the cam 16 is in the correct position. Then the controller 39 controls the stepping motor 19 to work. When the cam 16 starts to rotate, the infrared rays emitted by the transmitting end of the beam-type infrared sensor 37 are blocked. The receiving end sends a signal to the controller 39. At this time, the controller 39 determines that the cam 16 is in a rotating state. When the cam 16 rotates one circle, the through hole 38 returns to the position relative to the beam-type infrared sensor 37. The infrared rays emitted by the transmitting end of the beam-type infrared sensor 37 pass through the through hole 38 again. The receiving end receives the infrared rays again. The receiving end sends a signal to the controller 39. The controller 39 determines that the cam 16 rotates one circle, and the controller 39 cuts off the power supply. By providing the beam-type infrared sensor 37, the problem that the stepping motor 19 cannot automatically stop when a fault occurs can be effectively solved.

[0051] Embodiment 3 of the present invention: Please combine Figure 7-10 In this embodiment, a second cutting blade block 23 is further provided on the basis of the first or second embodiment.

[0052] A second blade block mounting hole 22 is opened on the front side wall 1 in the horizontal direction, and the second cutting blade block 23 is plugged into and slidably connected to the second blade block mounting hole 22. One end of the second cutting blade block 23 located in the box is fixedly connected to the lower end of the connecting plate 10, and a second discharge hole 24 is opened on the titanium plate blocking plate 4, and the second discharge hole 24 is opposite to the second blade block mounting hole 22.

[0053] In this embodiment, one end of the second cutting blade block 23 located in the box is fixedly connected to the lower end of the connecting plate 10, and the upper end of the connecting plate 10 is fixedly connected to the end of the first cutting blade block 3. The connecting plate 10 is used to simultaneously drive the first cutting blade block 3 and the second cutting blade block 23 to move.

[0054] The second cutting blade block 23 is used to cut the arc-shaped titanium plate. Since the arc-shaped titanium plate has a curvature, the top surface length of the connecting part between the two circular ring parts on the arc-shaped titanium plate is shorter than the bottom surface length. Therefore, the top side length of the cross-sectional shape of the second cutting blade block 23 is shorter than the bottom side length. The left and right sides of the cross-sectional shape of the second cutting blade block 23 are also concave arc shapes. The second cutting blade block 23 designed in this way also forms an arc surface at the cutting position when cutting the arc-shaped titanium plate.

[0055] The cross-sectional shape of the second material discharge hole 24 and the cross-sectional shape of the second blade block mounting hole 22 are the same as the cross-sectional shape of the second cutting blade block 23 and have the same size. The second material discharge hole 24 and the second blade block mounting hole 22 are arranged opposite to each other.

[0056] A second titanium plate positioning block 30 and a second titanium plate support plate 31 are fixedly provided on the outer wall of the front side wall 1. The top surface of the second titanium plate positioning block 30 is flush with the lower edge of the second knife block mounting hole 22. The second titanium plate support plate 31 is an arc-shaped plate. One end of the second titanium plate support plate 31 is fixedly connected to one end of the second titanium plate positioning block 30. The second titanium plate support plate 31 has a second side baffle 35.

[0057] The second titanium plate support plate 31 is customized according to the arc-shaped titanium plate and is used to place and support the arc-shaped titanium plate. The second titanium plate positioning block 30 is used to limit the arc-shaped titanium plate so that the position on the arc-shaped titanium plate waiting to be cut is aligned with the second cutting blade block 23.

[0058] The working principle of this embodiment refers to the working principle of embodiment 1. The difference between this embodiment and embodiment 1 is that when cutting the arc-shaped titanium plate, the arc-shaped titanium plate is placed on the second titanium plate support plate 31, and the arc-shaped titanium plate is positioned using the second titanium plate positioning block 30, and the arc-shaped titanium plate is cut when the second cutting blade block 23 extends out of the second blade block mounting hole 22. Other principles are the same as those of embodiment 1 and will not be repeated.

[0059] Embodiment 4 of the present invention: Please refer to Fig.11 and Fig.12 In this embodiment, a first storage space 41 and a second storage space 42 are formed in the top cover 9. The opening of the first storage space 41 is located on the left wall of the top cover 9, and the opening of the second storage space 42 is located on the right wall of the top cover 9. The first drawer 43 is plugged and slidably connected to the first storage space 41, and the second drawer 44 is plugged and slidably connected to the second storage space 42. Handles 45 are provided on the first drawer 43 and the second drawer 44.

[0060] A linear titanium plate can be placed in the first drawer 43, and an arc-shaped titanium plate can be placed in the second drawer 44, so that the storage and removal of the titanium plates are convenient.

[0061] Preferably, the bottom surface of the first drawer 43 is a plane, and the bottom surface of the second drawer 44 is an arc-shaped bottom surface that bends downward.

[0062] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
