Description

Technical Field

[0001] The utility model relates to the technical field of table tennis racket production and processing, and specifically relates to a double-sided mirror edge grinding device for table tennis rackets. Background Technique

[0002] During the actual production and preparation process of table tennis rackets, it is often necessary to perform edge grinding on the double-sided mirrors of table tennis rackets. It can be flattened by grinding the tiger's mouth, which is beneficial to ensuring that the hand is not injured when playing. However, there are still some problems when the double-sided mirror edge grinding device of table tennis rackets actually operates.

[0003] The double-sided mirror edge grinding device of table tennis rackets often can only achieve simple rotary grinding functions. Considering the irregular edges of table tennis racket products, this results in the need for users to assist in moving the edges of table tennis racket products along the edge grinding roller to achieve a comprehensive treatment of the double-sided mirror edge grinding of table tennis rackets. This semi-manual edge grinding method is neither safe nor efficient in processing. Based on this, we propose a new double-sided mirror edge grinding device for table tennis rackets to provide a more efficient edge grinding processing effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a double-sided mirror edge grinding device for table tennis rackets to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A double-sided mirror edge grinding device for table tennis rackets, including a lower bearing frame and a limiting chute for table tennis rackets. The top of the lower bearing frame is welded with an upper fixing frame. The limiting chute for table tennis rackets is arranged at the bottom end inside the upper fixing frame. The inner side wall of the limiting chute for table tennis rackets is provided with a mold cavity for table tennis rackets. The top of the lower bearing frame is fixed with a shelf for table tennis rackets that matches the mold cavity for table tennis rackets. The top of the upper fixing frame is fixed with a telescopic cylinder that matches the shelf for table tennis rackets. A driving machine base is arranged on the lower bearing frame. A first motor is installed inside the driving machine base. The output end of the first motor is connected with an edge grinding roller. A limiting slider that is slidably connected with the limiting chute for table tennis rackets is welded on the top of the edge grinding roller. At both ends on one side of the lower bearing frame, a first driving machine shell and a second driving machine shell are respectively installed. A second motor is installed at one end of the first driving machine shell and the second driving machine shell. A winding roller is wound with a traction rope connected to the top of the edge grinding roller, and an annular guide rope tube that matches the traction rope is arranged at the top end inside the upper fixing frame.

[0006] Preferably, guiding balls are evenly and movably connected to the bottom of the driving machine base and the edge grinding roller, which improves the stability effect when the driving machine base moves along the limiting chute for table tennis rackets and the edge grinding roller rotates.

[0007] Preferably, nano-ceramic anti-sticking coatings are applied to the outer side walls of the driving machine base and the upper fixing frame, improving the anti-fouling effect of the outer walls of the driving machine base and the upper fixing frame.

[0008] Preferably, a dismountable installation structure is formed between the edge grinding roller and the first motor through screws.

[0009] Preferably, a dust collection box is installed at the top end of the upper fixing frame, and an air extraction pipe component is fixed to the top end of the dust collection box.

[0010] Preferably, suction ports penetrating the top of the upper fixing frame are uniformly arranged at the bottom of the air extraction pipe component.

[0011] Preferably, a dust removal exhaust fan is installed at one end of the dust collection box.

[0012] Preferably, a filter screen layer is arranged at one end of the dust collection box close to the dust removal exhaust fan.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1). By installing an edge grinding roller, etc., when the device actually performs edge grinding operation, the second motors on the first driving machine shell and the second driving machine shell are controlled by an external control device. One starts the winding roller to wind up the traction rope, while the other starts the corresponding winding roller to perform synchronous wire releasing treatment on the corresponding traction rope. And these traction ropes will pass through the annular wire guiding pipe to realize the limiting and guiding of the traction ropes. Thus, by using two groups of mutually cooperating rope traction driving mechanisms, the driving machine base can be continuously moved along the limiting sliding groove for the table tennis racket, and at the same time, the first motor on the driving machine base will drive the edge grinding roller to rotate to realize the grinding operation on the double-sided mirror edges of the table tennis racket product. Furthermore, the device can realize the continuous and one-time processing and forming of the double-sided mirror edge grinding of the table tennis racket, which solves the problem that the edges of the table tennis racket are irregular and not easy to be ground into shape at one time and improves the processing efficiency.

[0015] (2). By installing a telescopic cylinder, etc., the device optimizes its own performance. The user first places the table tennis racket product to be edge-ground from top to bottom onto the table tennis racket shelf through the table tennis racket mold cavity and starts the telescopic cylinder to press down its output end to fix the table tennis racket product. This enables the device to achieve a good positioning and fixing effect on the table tennis racket product, ensuring that the edges of the table tennis racket product just contact the edge grinding roller after installation.

[0016] (3) The double-sided mirror edge grinding device for table tennis rackets is equipped with a dust collection box and other components, which optimizes its own structure. When the dust extraction fan is started, a negative pressure is generated inside the dust collection box. Then, through the action of the air extraction pipe component with suction ports connected to the inside of the dust collection box, the dust-containing gas can be sucked into the dust collection box during edge grinding. The dust and debris in the dust-containing gas will be retained inside the dust collection box under the blockage of the filter screen layer inside the dust collection box, realizing the collection of dust and debris. This enables the device to timely clean up the debris generated during edge grinding processing, thereby optimizing the processing environment and processing effect. Description of the Drawings

[0026] During use, the user first places the table tennis racket product to be edge-ground from top to bottom onto the table tennis racket shelf 17 through the table tennis racket mold cavity 12 for positioning, and starts the telescopic cylinder 7 to press down its output end to fix the table tennis racket product. This enables the device to achieve a good effect of positioning, installing, and fixing the table tennis racket product, ensuring that the edge of the table tennis racket product just touches the edge grinding roller 14 after installation;

[0027] A driving machine base 2 is arranged on the lower carrier 4. A first motor 15 is installed inside the driving machine base 2. The output end of the first motor 15 is connected to an edge grinding roller 14. A limit slider 10 that is slidably connected to the table tennis racket limit chute 11 is welded to the top of the edge grinding roller 14;

[0028] At both ends of one side of the lower carrier 4, a first driving machine shell 5 and a second driving machine shell 6 are respectively installed. A second motor 19 is installed at one end of each of the first driving machine shell 5 and the second driving machine shell 6.

During actual edge grinding operation, under the control of the external control equipment, the second motor 19 on the first drive housing 5 and the second drive housing 6 starts one winding roller 20 to wind up the traction rope 3, while the other starts the corresponding winding roller 20 to perform a synchronous wire releasing process on the corresponding traction rope 3. These traction ropes 3 will pass through the annular wire guiding pipe 1 to achieve the limiting and guiding of the traction ropes 3. Thus, by using two sets of mutually cooperating rope traction drive mechanisms, the drive base 2 can be continuously moved along the table tennis racket limiting chute 11. At the same time, the first motor 15 on the drive base 2 drives the edge grinding roller 14 to rotate, achieving the grinding operation on the double-sided mirror edges of the table tennis racket product. Furthermore, the device can achieve continuous and one-time processing and forming of the double-sided mirror edge grinding of the table tennis racket, solving the problem that the edges of the table tennis racket are irregular and difficult to be edge-ground into shape at one time, and improving the processing efficiency. In addition, the dust extraction fan 18 is started, creating a negative pressure inside the dust collection box 8. Then, through the action of the air extraction pipe member 16 provided with air suction ports 21 and connected to the inside of the dust collection box 8, the dust-containing gas can be drawn into the dust collection box 8 during edge grinding. The dust and debris in the dust-containing gas will be retained inside the dust collection box 8 under the barrier of the filter screen layer inside the dust collection box 8 to achieve dust and debris collection. This enables the device to timely clean the debris generated during edge grinding processing, thereby optimizing the processing environment and processing effect.
