Description

Technical Field

[0001] The utility model relates to the field of ballpoint pen ball production, in particular to a polishing device for ballpoint pen ball production. Background Art

[0002] The ball of a ballpoint pen is the part of the pen tip, which is used to control the flow of ink and form text or patterns on paper. The ball is usually made of wear-resistant materials such as steel, tungsten carbide or ceramics. It is smooth, strong and has good wear resistance to ensure smoothness and durability when writing. Common ball diameters include 0.5 mm, 0.7 mm and 1.0 mm. Users can choose the appropriate size according to their writing needs. The ball of the ballpoint pen needs to be polished during the production process.

[0003] After searching, the Chinese patent announcement number CN220074348U is found, which discloses a polishing device for producing ballpoint pen balls.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, a polishing device for producing ballpoint pens comprises a polishing box 1, a feed pipe 101 is welded on the top of the polishing box 1, a discharge pipe 102 is welded on one side of the polishing box 1, and an openable maintenance window is provided on the front side of the polishing box 1 to facilitate replacement or maintenance of the equipment inside the polishing box 1.

[0026] A polishing mechanism is arranged in the polishing box 1, and the polishing mechanism includes a rotating motor 201 bolted to the top of the polishing box 1, the output end of the rotating motor 201 is connected to the rotating shaft 202 through a coupling, and the outer wall of the rotating shaft 202 is provided with multiple groups of polishing components. When the rotating motor 201 is started, the rotating motor 201 drives the rotating shaft 202 to drive the multiple groups of polishing components to revolve.

[0027] The polishing assembly includes a rotating rod 203 rotatably connected to a rotating shaft 202, a plurality of connecting rods 204 are welded to the rotating rod 203, sandpaper for ball polishing is pasted on the outer wall of the connecting rod 204, a gear 205 is fixedly connected to the end of the connecting rod 204, a gear ring 206 is fixedly connected between the inner walls of the polishing box 1, the gear 205 is meshed with the gear ring 206, and when the rotating rod 203 drives the gear 205 to revolve, the gear 205 is driven by the gear ring 206 to drive the rotating rod 203 to rotate.

[0028] A filter screen 3 is connected between the inner walls of the polishing box 1, and the filter screen 3 is set at an angle. The discharge pipe 102 is located at the lower end of the filter screen 3. A plurality of connecting plates 501 are fixedly connected to the outer wall of the rotating shaft 202, and the connecting plates 501 are set horizontally. The connecting plates 501 are located between the highest point and the lowest point of the filter screen 3. When the rotating shaft 202 rotates, the connecting plates 501 will be driven to rotate. When the connecting plates 501 rotate to the higher end of the filter screen 3, the filter screen 3 will be pressed downward. When the connecting plates 501 are turned away, the filter screen 3 rebounds upward under the action of elastic force, and the balls on the filter screen 3 are bounced up, which facilitates the contact between the balls and the sandpaper on the connecting rod 204, thereby improving the polishing efficiency.

[0029] A vibration assembly is provided at the bottom of the filter 3, and the vibration assembly includes a plurality of mounting plates 502 fixedly connected to the outer wall of the rotating shaft 202, a plurality of push rods 503 are fixedly connected to the top of the mounting plate 502, and a protrusion 504 is fixedly connected to the bottom of the filter 3, and the lowest end of the protrusion 504 is lower than the highest end of the push rod 503, so that the push rod 503 and the protrusion 504 can abut against each other. After abutting, a partial area of ​​the filter 3 is lifted upward by the protrusion 504. When the push rod 503 is separated from the protrusion 504, the protrusion 504 is reset under the action of the elastic force of the filter 3, so that the filter 3 produces a certain vibration.

[0030] A fan 6 is bolted to one side of the polishing box 1, and a plurality of air inlet holes 601 are provided on the inner wall of the polishing box 1. An air outlet hole 602 is provided on one side of the polishing box 1. The air inlet holes 601 are located above the filter 3, and the air outlet holes 602 are located below the filter 3. When the wind from the fan 6 is discharged into the area above the filter 3 through the air inlet holes 601, the beads are blown up and scattered around, thereby increasing the probability of the beads touching the sandpaper and improving the polishing effect. At the same time, part of the gas in the polishing box 1 passes through the filter 3 and is discharged from the air outlet holes 602, providing a downward force to the debris on the filter 3, thereby promoting the separation of the debris from the beads.

[0031] The inner bottom wall of the polishing box 1 is slidably connected with a collecting box 4 , the front side of the collecting box 4 extends out of the polishing box 1 and is welded with a handle, and the sieved debris is collected through the collecting box 4 .

[0032] Working principle: the balls are put into the polishing box 1 through the feed pipe 101, and the rotating motor 201 is started. The rotating motor 201 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the rotating rod 203 to rotate. When the rotating rod 203 revolves, the gear 205 is driven by the gear ring 206 to drive the rotating rod 203 to rotate, and the rotating rod 203 drives the connecting rod 204 to rotate. The sandpaper on the connecting rod 204 is used to polish the balls. When the rotating shaft 202 rotates, the connecting plate 501 is driven to rotate. When the connecting plate 501 rotates to the higher end of the filter 3, the filter 3 is pressed downward. When the connecting plate 501 rotates away, the filter 3 rebounds upward under the action of elastic force, and the balls on the filter 3 are bounced up, so that the balls are in contact with the sandpaper on the connecting rod 204, thereby improving the polishing efficiency. The rotating shaft 202 rotates At the same time, it will also drive the mounting plate 502 to rotate, and the mounting plate 502 will drive the push rod 503 to rotate. When the push rod 503 abuts against the protrusion 504, the protrusion 504 will push up part of the filter 3. When the push rod 503 separates from the protrusion 504, the protrusion 504 is reset under the action of the elastic force of the filter 3, causing the filter 3 to vibrate to a certain extent, so that the debris generated by polishing can fall into the collection box 4 in time, so as to achieve the separation of the balls and the debris, and avoid the debris from affecting the efficiency of the ball polishing. While polishing, the fan 6 is started, and the wind force of the fan 6 is used to blow up the balls, so that the balls are scattered everywhere, increasing the probability of the balls touching the sandpaper and improving the polishing effect. At the same time, part of the gas in the polishing box 1 passes through the filter 3 and is discharged from the air outlet 602, providing a downward force to the debris on the filter 3, thereby promoting the separation of the debris from the balls.
