Description

Technical Field

[0001] The invention relates to the technical field of plate cutting, and in particular to a table tennis racket plate cutting device. Background Art

[0002] Table tennis rackets are made up of three parts: the base plate, rubber and sponge. The base plate includes the racket face and the handle. After the racket face is cut and processed, the handle is glued to the racket face.

[0003] In the existing surface cutting, most of the engraving machines are used. When cutting, a piece of board is fixed under the milling cutter, and then the engraving machine works, and the milling cutter with a pre-planned path cuts the board. However, in this way, a single milling cutter can only cut one piece of board. If the cutting efficiency is to be improved, multiple stations are usually added to work simultaneously. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a table tennis racket sheet cutting device, including a box body, a cutting platform is arranged inside the box body, a first support and a second support are arranged opposite to each other at the upper end of the cutting platform, a first motor is fixedly connected to the first support, a first clamping plate is fixedly connected to the output end of the first motor, a first electric cylinder is fixedly connected to the second support, a first telescopic rod is extended to one end of the first electric cylinder, and a second clamping plate is rotatably connected to the end of the first telescopic rod. The contour shape of the first clamping plate and the second clamping plate are consistent, which is the shape of the racket face of the table tennis racket, and can be replaced according to the production of different models of table tennis rackets. During production, the sheet is clamped between the first clamping plate and the second clamping plate, and then the first motor drives the sheet to rotate.

[0005] A cutting mechanism is provided inside the box, and the cutting mechanism is located above the first clamping plate and the second clamping plate, and the cutting mechanism includes a fourth telescopic rod, and a corner piece is fixedly connected to the lower end of the fourth telescopic rod, and a second motor is fixedly connected to the lower side wall of the corner piece horizontally, and a roller is fixedly connected to the output end of the second motor. The roller is a cylindrical structure, and can cut the racket faces of multiple table tennis rackets at one time, thereby improving production efficiency, and the second motor is started to drive the roller to rotate.

[0006] The lower side wall of the corner piece is rotatably provided with a roller, the side wall of the first clamping plate is provided with a guide surface, and the roller is matched with the guide surface. During the hob cutting process, the roller is always in contact with the guide surface, and this arrangement is used to improve the cutting accuracy.

[0007] Preferably, the cutting mechanism further comprises a third electric cylinder, a third telescopic rod is extended from the lower end of the third electric cylinder, and the fourth telescopic rod extends from the lower end of the third telescopic rod. The third electric cylinder works to realize the extension and retraction of the third telescopic rod, thereby controlling the height of the roller. When the roller is in operation, the third electric cylinder is actuated to lower the roller toward the plate.

[0008] Preferably, a spring is provided inside the third telescopic rod, and the lower end of the spring abuts against the upper end of the fourth telescopic rod. The spring is used for tensioning, so that the roller can always keep in contact with the guide surface, while also avoiding the problem of excessive contact force between the two.

[0009] Preferably, a limit frame is provided above the cutting platform, and the two ends of the limit frame are respectively slidably matched in the preset sliding grooves of the side walls of the first support and the second support. That is, the limit frame can be raised and lowered. Preferably, the limit frame includes two cross bars of angle steel structure, a connecting rod is arranged between the cross bars, a positioning rod is arranged between the cross bars, and the upper contour of the positioning rod is the same as the lower contour of the first clamping plate and the second clamping plate. When the limit frame is used, it is lifted to the first clamping plate and the second clamping plate, and then the first clamping plate and the second clamping plate are matched on the positioning rod, and the processed plate is placed, and then the first electric cylinder is actuated to clamp the plate. This method is convenient for clamping the plate, and also ensures the alignment accuracy between the first clamping plate and the second clamping plate, thereby improving the cutting quality of the racket surface.

[0010] Preferably, a second electric cylinder is provided inside the box, a second telescopic rod is extended from the upper end of the second electric cylinder, and the upper end of the second telescopic rod is fixedly connected to the end of the limit frame.

[0012] Preferably, a box door is provided on the front side of the box body. The box door is opened to take and place the workpiece, thereby ensuring the safety of the operation.

[0013] The beneficial effects of the present invention are as follows: 1. Multiple plates can be clamped and fixed between the first clamping plate and the second clamping plate, and then cut by a rolling cutter, which has the advantage of high production efficiency.

[0014] 2. The roller, guide surface, fourth depth mountain, spring, etc. are set to improve the cutting accuracy and avoid the hob from hitting the knife.

[0015] 3. A lifting limit frame is provided to facilitate the placement of the board, which is conducive to rapid production. The cutting structure is located inside the box to isolate the pollution of wood chips and dust. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment 1

[0019] Combination Figure 1 and Figure 2As shown, a table tennis racket board cutting device includes a box body 2, which is in the shape of a rectangular parallelepiped. A cutting platform 3 is arranged inside the box body 2. A first support 7 and a second support 14 are arranged opposite to each other at the upper end of the cutting platform 3. A first motor 6 is fixedly connected to the first support 7. A first clamping plate 11 is fixedly connected to the output end of the first motor 6. Starting the first motor 6 can drive the first clamping plate 11 to rotate. A first electric cylinder 15 is fixedly connected to the second support 14. A first telescopic rod 13 is extended from one end of the first electric cylinder 15. The end of the first telescopic rod 13 is rotatably connected to the second clamping plate 12. When the first electric cylinder 15 is actuated, the first telescopic rod 13 is retracted. When processing the board, the board is first placed between the first clamping plate 11 and the second clamping plate 12. Then the first electric cylinder 15 works, the second clamping plate 12 moves toward the first clamping plate 11, and then the board is tightly clamped.

[0020] like Figure 2 and Figure 3 As shown, a cutting mechanism 8 is provided inside the box body 2 for cutting the plate, and the cutting mechanism 8 is located above the first clamp plate 11 and the second clamp plate 12, and the cutting mechanism 8 includes a fourth telescopic rod 83, and the lower end of the fourth telescopic rod 83 is fixedly connected with an angle piece 82, and the side shape of the angle piece 82 is L-shaped, and the lower side wall of the angle piece 82 is horizontally fixedly connected with a second motor 87, and the output end of the second motor 87 is fixedly connected with a roller 81, and the second motor 87 is started to drive the roller 81 to rotate, and the roller 81 cuts the edge of the plate along the side wall of the first clamp plate 11.

[0021] like Figure 3 As shown, a roller 88 is rotatably provided on the lower side wall of the corner piece 82, and a guide surface 10 is provided on the side wall of the first clamping plate 11. The roller 88 is matched on the guide surface 10. By providing the roller 88 and the guide surface 10, the cutting accuracy is ensured, and the roller 81 is prevented from colliding with the cutter.

[0022] The cutting mechanism 8 also includes a third electric cylinder 86, which is fixedly connected to the upper wall of the box body 2. A third telescopic rod 84 is extended from the lower end of the third electric cylinder 86, and a fourth telescopic rod 83 extends from the lower end of the third telescopic rod 84. When the third electric cylinder 86 is working, the third telescopic rod 84 rises or falls. When cutting, the roller cutter 81 is controlled to descend.

[0023] A spring 85 is arranged inside the third telescopic rod 84, and the lower end of the spring 85 abuts against the upper end of the fourth telescopic rod 83. That is, the spring 85 is used to keep the fourth telescopic rod 83 extending out of the third telescopic rod 84. When cutting, when the roller 88 contacts the guide surface 10, the spring 85 plays a buffering role, and the trajectory of the roller 88 moving on the guide surface 10 is the contour of the produced racket surface. In this way, the accuracy of racket surface cutting can be controlled.

[0024] like Figure 2 As shown, a limiting frame 9 is arranged above the cutting platform 3, and both ends of the limiting frame 9 are respectively slidably matched in the preset sliding grooves on the side walls of the first support 7 and the second support 14, so that the limiting frame 9 can be raised and lowered.

[0025] like Figure 5 As shown, the limit frame 9 includes two cross bars 92 of angle steel structure, and the plate can be placed between the two cross bars 92. At the same time, the structure of the angle steel facilitates the front and back alignment of the plate. A connecting rod 91 is arranged between the cross bars 92. The connecting rod 91 is used to improve the structural strength of the limit frame 9. A positioning rod 93 is arranged between the cross bars 92, and the upper contour of the positioning rod 93 is the same as the lower contour of the first clamping plate 11 and the second clamping plate 12. The positioning rod 93 is used for positioning the first clamping plate 11 and the second clamping plate 12, so that the first clamping plate 11 and the second clamping plate 12 are accurately aligned. The use of the limit frame 9 can greatly facilitate the placement of the plate and improve the cutting accuracy.

[0026] like Figure 4 As shown, a second electric cylinder 16 is provided inside the box body 2, and a second telescopic rod 17 is extended from the upper end of the second electric cylinder 16. The upper end of the second telescopic rod 17 is fixedly connected to the end of the limit frame 9, that is, when the second electric cylinder 16 is working, the second telescopic rod 17 is extended and retracted. When the plate is clamped, the second electric cylinder 16 works to lift the limit frame 9. When the plate is cut, the second electric cylinder 16 works again to lower the limit frame 9 onto the cutting platform 3.

[0027] like Figure 1 As shown, a drop port 5 is provided in the middle of the upper end of the cutting platform 3, and a collecting box 4 is provided below the drop port 5. A narrowed slide is provided at the drop port 5 to ensure that the wood chips generated by cutting enter the collecting box 4. When dumping, just hold the preset embedded handle on the front of the collecting box 4.

[0028] The front of the box body 2 is provided with a box door 1 for improving the safety of production and preventing wood chips from spreading in the workshop. Embodiment 2

[0029] The difference between this embodiment and the above-mentioned embodiment is that Figure 6 As shown, the cutting mechanism 8 also includes a third motor 89, a tension spring 810, a guide wheel 811, a transmission belt 812 and a transmission wheel 813. At this time, the transmission wheel 813 replaces the second motor 87, and the transmission wheel 813 and the roller 81 are coaxially fixedly connected.

[0030] The transmission belt 812 is connected around the output end of the third motor 89 and the transmission wheel 813, and the third motor 89 is started to drive the roller 81 to rotate. Relative to the position of the second motor 87, the third motor 8 can select a type with greater power to ensure that the roller 81 has a strong cutting ability, thereby improving the cutting efficiency.

[0031] The tension spring 810 and the guide wheel 811 are used for tensioning. During the lifting process of the roller 81, the position of the third motor 89 changes to ensure that the transmission belt 812 can work normally. Therefore, the tension spring 810 and the guide wheel 811 are provided for tensioning. The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
