[0028] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.
[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0030] In the specific implementation process, the automatic wax sealing device for pen refills can be an independent processing device, or it can be a workstation connected to other processing devices. The following is an example of an online device consisting of an automatic wax sealing device for pen refills and a pen refill line test device.
[0031] like Figure 1-11 As shown, an automatic wax sealing device for pen refills includes a machine 100 and a controller. The machine 100 is equipped with a material transport mechanism 200 and a cam drive mechanism 300, each connected to the controller. A pen tip wiping mechanism and a wax sealing mechanism are sequentially arranged on the machine 100 along the direction of movement of the material transport mechanism 200. The material transport mechanism 200 and the wax sealing mechanism are each connected to the cam drive mechanism 300. The pen tip wiping mechanism is used to wipe the pen tip of the pen refill on the material transport mechanism 200. During processing, the pen tip wiping mechanism first wipes the pen tip of the pen refill on the material transport mechanism 200 clean, and then the wax sealing mechanism is used to seal the pen refill with wax. The provision of the pen tip wiping mechanism can remove dirt such as ink on the pen tip, thereby improving the stability of the wax sealing operation and increasing the processing yield.
[0032] The wax sealing mechanism includes a wax sealing rotary table 1, which is rotatably connected to the machine 100 and connected to a controller, which can be used to control the rotation of the wax sealing rotary table 1. The wax sealing rotary table 1 can be any existing structure that can achieve rotary material transportation, such as a motor divider structure. Multiple refill holders 2 are installed on the wax sealing rotary table 1. The upper cover of the machine 100 is sequentially provided with a grabbing assembly 3, a wax sealing assembly 4, an air drying assembly 5, a material picking assembly 6, and a discharge mechanism 7 along the direction of movement of the wax sealing rotary table 1. The grabbing assembly 3 is used to grab refills from the discharge mechanism 200 and place them on the refill holder 2. The wax sealing assembly 4 is used to wax the refills on the refill holder 2. The air drying assembly 5 is used to blow air on the refills on the refill holder 2. The material picking assembly 6 is used to grab refills from the refill holder 2 and place them on the discharge mechanism 7. The discharge mechanism 7 is used to deliver the processed refills out of the machine 100.
[0033] During the specific operation, the pen refill is first placed on the material transport mechanism 200 through an external device, and the pen refill is sequentially transported to the pen tip wiping mechanism through the material transport mechanism 200. The pen tip can be wiped clean by the pen tip wiping mechanism to remove ink and other dirt on the pen tip; the pen refill is then transported to the corresponding position of the wax sealing mechanism through the material transport mechanism 200, and the material taking component 6 grabs the pen refill from the material transport mechanism 200 and places it in the pen refill fixture 2 on the wax sealing rotating table 1; and then The wax sealing rotary table 1 transports the pen refill to the corresponding positions of the wax sealing component 4, the air drying component 5 and the material taking component 6 in sequence. The wax sealing component 4 will seal the pen refill on the pen refill fixture 2 with wax, and the air drying component 5 can blow the wax sealing on the pen refill fixture 2 dry to solidify it. The material taking component 6 will grab the pen refill with solidified wax sealing from the pen refill fixture 2 and place it on the unloading mechanism 7; the processed pen refill is then sent out of the machine 100 through the unloading mechanism 7, completing the automatic wax sealing process.
[0034] The automatic wax sealing device for pen refills can automatically complete loading, wiping the pen tip, sealing wax and unloading, reducing manual participation, improving the degree of automation of the equipment and reducing labor costs; using machines instead of manual operations can also greatly improve the wax sealing efficiency of pen refills.
[0035] like Figure 2 、 Figure 3 As shown, the pen tip wiping mechanism includes a wiping rotating assembly 8 and a wiping assembly 9. The wiping rotating assembly 8 can drive the pen core on the material transport mechanism 200 to rotate, and the wiping assembly 9 can be connected to the pen core on the material transport mechanism 200 to remove the ink on the pen tip. The wiping assembly 9 includes a wiping fixed seat 91, which is connected to the machine 100. The wiping fixed seat 91 is provided with a unwinding roller 92, a wiping roller 93 and a cloth pulling assembly. The unwinding roller 92 and the wiping roller 93 are rotatably connected to the wiping fixed seat 91 respectively. The unwinding roller 92 is used to place the rolled wiping cloth. The rolled wiping cloth can be stretched and laid on the wiping roller 93 and the cloth pulling assembly in sequence. The wiping roller 93 is connected to the pen core on the material transport mechanism 200.
[0036] Before processing, the coiled wiping cloth is first placed on the unwinding roller 92, and then the coiled wiping cloth is stretched and laid on the wiping roller 93 and the cloth pulling assembly in sequence. During specific processing, the material transport mechanism 200 transports the pen refills to the corresponding positions of the pen tip wiping device in sequence. At this time, the pen tip of the pen refill on the material transport mechanism 200 will be connected with the coiled wiping cloth on the wiping roller 93. The pen refill is driven to rotate on the material transport mechanism 200 by the wiping rotating assembly 8, and the pen tip of the pen refill can be wiped clean by the coiled wiping cloth on the wiping roller 93. After wiping is completed, the coiled wiping cloth is pulled by the cloth pulling assembly so that a new wiping cloth is laid on the wiping roller 93 for the next round of wiping.
[0037] like Figure 5As shown, the wiping rotating assembly 8 includes a rotating fixed seat 81, which is fixedly mounted on the machine table 100 and is placed on one side of the material transporting mechanism 200. A rotating cylinder 82 is mounted on the rotating fixed seat 81, and a pressing mounting block 83 is provided on the output end of the rotating cylinder 82. A pressing block 84 is provided on the pressing mounting block 83. The pressing block 84 can abut against the pen core on the material transporting mechanism 200, and the rotating cylinder 82 can drive the pressing block 84 to move horizontally, thereby driving the pen core to rotate on the material transporting mechanism 200. During processing, when the material transporting mechanism 200 transports the pen refill to the place where it connects with the rolled wiping cloth on the wiping roller 93, the pen refill is just below the pressing block 84; the cam driving device 300 on the pen refill wax sealing device drives the material transporting mechanism 200 to rise, so that the pen refill on the material transporting mechanism 200 contacts the pressing block 84; and then the pressing mounting block 83 is driven to move by the rotating cylinder 82, driving the pressing block 84 to move laterally together, and the pressing block 84 will push the pen refill on the material transporting mechanism 200 to rotate in place, so that the rolled wiping cloth on the wiping roller 93 can wipe the pen tip of the pen refill clean.
[0038] It should be noted that, in practice, multiple bearings can be installed on the transport mechanism 200 at positions corresponding to the wiping rotary assembly 8, and the bearings can rotate in place. When the transport mechanism 200 transports the pen refill directly below the pressing block 84, the pen refill is positioned on the two bearings. When the rotary cylinder 82 drives the pressing block 84, the pen refill can rotate on the bearings. The provision of bearings allows the pen refill to rotate smoothly on the transport mechanism 200, improving processing stability.
[0039] To limit and guide the movement of the pressing block 84, a rotating guide rail 85 is provided on the rotating fixed seat 81, and the pressing mounting block 83 is slidably engaged with the rotating guide rail 85. When the rotary cylinder 82 is in operation, the pressing mounting block 83 slides on the rotating guide rail 85. Through the cooperation of the two, the movement of the pressing block 84 is limited and guided, improving the transmission accuracy and stability, and enhancing the stability of the processing.
[0040] A flexible rubber strip 86 is installed on the lower end surface of the pressing block 84. By providing the flexible rubber strip 86, the pressing block 84 is in soft contact with the pen lead, which can prevent the pressing block 84 from crushing the pen lead. At the same time, the flexible rubber strip 86 can also increase the friction with the pen lead, so that the pressing block 84 can more smoothly push the pen lead to rotate on the material transport mechanism 200, thereby improving the stability of the processing.
[0041] like Figure 3As shown, the cloth pulling assembly includes a cloth pulling motor 94 and a cloth pulling roller 95. The cloth pulling motor 94 is fixedly mounted on the wiping fixed seat 91, and the cloth pulling roller 95 is rotatably connected to the wiping fixed seat 91. The output end of the cloth pulling motor 94 is connected to the cloth pulling roller 95. Before processing, the rolled wiping cloth on the unwinding roller 92 is stretched and laid on the cloth pulling roller 95; when the rolled wiping cloth on the wiping roller 93 completes a round of wiping the pen tip, the cloth pulling motor 94 is controlled to drive the cloth pulling roller 95 to rotate, thereby pulling the rolled wiping cloth to move, and the rolled wiping cloth drives the unwinding roller 92 to rotate, and lays a new wiping cloth on the wiping roller 93, so as to wipe the pen tip of the next batch of pen refills, thereby realizing the continuous wiping operation of the pen refills on the material transport mechanism 200.
[0042] Specifically, if Figure 4 As shown, a driving wheel 96 is mounted on the output end of the cloth pulling motor 94, a driven wheel 97 is mounted on one end of the cloth pulling roller 95, and a driving belt 98 is sleeved on the driving wheel 96 and the driven wheel 97. During processing, by controlling the cloth pulling motor 94 to work, the driving wheel 96 can be driven to rotate, thereby driving the driving belt 98 to move; the driving belt 98 pulls the driven wheel 97 and the cloth pulling roller 95 to rotate, thereby achieving the purpose of pulling the roll material wiping cloth.
[0043] like Figure 4 As shown, in a specific implementation process, in order to facilitate the winding and collection of the used roll wiping cloth, a rotatable recovery roller 99 is provided on the wiping fixed seat 91, and a first transmission wheel 910 is provided at one end of the recovery roller 99, and a second transmission wheel 911 is provided at one end of the unwinding roller 92. A transmission belt 912 is sleeved on the driven wheel 97, the first transmission wheel 910 and the second transmission wheel 911. Through the cooperation of the first transmission wheel 910, the second transmission wheel 911 and the driven wheel 97, the cloth pulling motor 94 can simultaneously pull the cloth pulling roller 95, the unwinding roller 92 and the recovery roller 99 to rotate synchronously when working, thereby improving the stability of the transmission, and can not only achieve the stable laying of new wiping cloth on the wiping roller 93, but also the stable winding of the used wiping cloth.
[0044] like Figure 4As shown, a transmission tensioning block 913 is installed on the wiping fixed seat 91. The transmission tensioning block 913 is adjustable and limitedly connected to the wiping fixed seat 91. A rotatable tensioning wheel 914 is provided on the transmission tensioning block 913. The transmission belt 912 abuts against the outer wall of the tensioning wheel 914. The transmission belt 912 can be tightened or loosened by adjusting the position of the transmission tensioning block 913. During the assembly of the wiping assembly 9, the transmission belt 912 is first sleeved on the driven wheel 97, the first transmission wheel 910 and the second transmission wheel 911 respectively; then the transmission tensioning block 913 is installed. By adjusting the position of the transmission tensioning block 913 on the wiping fixed seat 91, the tensioning wheel 914 abuts against the transmission belt 912, thereby tightening the transmission belt 912 so that the first transmission wheel 910 and the second transmission wheel 911 can be pulled to rotate by the transmission belt 912. During use, if the transmission belt 912 becomes loose, the position of the transmission tensioning block 913 can be adjusted to tighten the transmission belt 912 .
[0045] like Figure 3 As shown, in order to improve the stability of the rolled wiping cloth during the pulling process, a plurality of tensioning rollers 915 are installed on the wiping fixed seat 91. The tensioning rollers 915 are rotatably connected to the wiping fixed seat 91, and the rolled wiping cloth on the unwinding roller 92 can be laid on each tensioning roller 915. Before processing, the rolled wiping cloth is placed on the unwinding roller 92, and then one end of the rolled wiping cloth is pulled and laid on the tensioning roller 915, the wiping roller 93, the cloth pulling roller 95 and the recycling roller 99 in sequence; by laying the rolled wiping cloth on the tensioning roller 915, the wiping cloth laid on the wiping roller 93 can be tightened, so that it is convenient to wipe the pen refill on the material transport mechanism 200 during operation.
[0046] like Figure 2 As shown, the wax sealing mechanism also includes a leveling and aligning component, which is connected to the wax sealing rotating table 1 and is arranged between the material taking component 6 and the wax sealing component 4; the leveling and aligning component is used to level all the refills on the refill fixture 2 so that the lower end surfaces of the refills are on the same horizontal line.
[0047] In this embodiment, the leveling and straightening component includes a first leveling component 10 and a second leveling component 11 arranged in sequence along the movement direction of the wax sealing rotary table 1. The first leveling component 10 and the second leveling component 11 can be connected to the refill fixture 2 respectively. The first leveling component 10 is used to level the upper end of the refill on the refill fixture 2, and the second leveling component 11 is used to level the lower end of the refill on the refill fixture 2.
[0048] like Figure 6 、 Figure 7As shown, the refill fixture 2 includes a fixture fixing block 21, which is provided with a plurality of refill placement holes 22 for placing the refills to be processed. Limiting blocks 23 are respectively installed at positions on the fixture fixing block 21 corresponding to the refill placement holes 22. The limiting blocks 23 are hinged to the fixture fixing block 21 via latches, and the limiting blocks 23 can rotate and swing along the latches. A limiting pin 24 is fixedly installed on each limiting block 23, and the limiting pin 24 can extend into the corresponding refill placement hole 22. By pushing the limiting block 23 to rotate and swing on the fixture fixing block 21, the limiting pin 24 can be extended into or out of the refill placement hole 22. When the refill is placed in the refill placement hole 22, the limiting pin 24 extends into the refill placement hole 22, and the end of the limiting pin 24 contacts the side wall of the refill, thereby limiting the refill in the refill placement hole 22; by driving the limiting pin 24 out of the refill placement hole 22, the refill can be released from the refill placement hole 22, thereby facilitating the sliding of the refill on the fixture fixing block 21, or directly removing the refill from the fixture fixing block 21.
[0049] like Figure 1 As shown, in this embodiment, a first switch 12 is provided on the machine 100 at positions corresponding to the gripping assembly 3, the first leveling assembly 10, and the material picking assembly 6. The first switch 12 is provided with a lifting push rod. The first switch 12 can drive the lifting push rod to move up and down, thereby causing the lifting push rod to abut against the limit block 23 on the corresponding refill fixture 2, thereby driving the limit block 23 to rotate and swing along the latch, causing the limit pin 24 to extend into or out of the corresponding refill placement hole 22. A second switch 13 is provided on the machine 100 at a position corresponding to the second leveling assembly 11. The second switch 13 is provided with a transverse push rod. The second switch 13 can drive the transverse push rod to move laterally, causing the transverse push rod to abut against the limit block 23 on the corresponding refill fixture 2, thereby driving the limit block 23 to rotate and swing along the latch, causing the limit pin 24 to extend into or out of the corresponding refill placement hole 22.
[0050] In this embodiment, there are 10 refill placement holes 22 distributed at equal intervals on each clamp fixing block 21, so that the refill automatic wax sealing device can perform wax sealing operations on 10 refills at the same time; in other embodiments, the number of refill placement holes 22 on the clamp fixing block 21 can also be any other number.
[0051] like Figure 8As shown, the grabbing assembly 3 includes a grabbing mounting seat 31, which is connected to a cam driving device 300. The cam driving device 300 can drive the grabbing mounting seat 31 to move up and down. A grabbing guide block 32 is provided on the grabbing mounting seat 31, and a grabbing cylinder 33 and a grabbing guide rail 34 are provided on the grabbing guide block 32. A grabbing slider 35 is provided on the output end of the grabbing cylinder 33. The grabbing slider 35 is slidably engaged with the grabbing guide rail 34. A rotatable clamping jaw mounting shaft 36 is provided on the grabbing slider 35. A plurality of clamping jaw cylinders 37 are provided at one end of the clamping jaw mounting shaft 36, and a grabbing guide wheel 38 is provided at the other end. The grabbing guide wheel 38 is eccentrically arranged with the clamping jaw mounting shaft 36. An L-shaped guide groove 39 is provided on the grabbing mounting seat 31. The grabbing guide wheel 38 extends out of the L-shaped guide groove 39 and is slidably limitedly connected to the L-shaped guide groove 39.
[0052] During specific operation, the material transport mechanism 200 drives the refill clamp 2 to the corresponding position of the grabbing component 3, and then controls the first switch 12 aligned with the grabbing component 3 to work. The operation of the first switch 12 causes the lifting push rod to push the limit block 23 to rotate and swing along the pin, so that the limit pin 24 extends out of the corresponding refill placement hole 22. After the transport mechanism 200 transports the wiped pen refill to the grabbing position of the grabbing assembly 3, the grabbing slide 35 is driven to slide on the grabbing guide rail 34 by the grabbing cylinder 33, and the grabbing slide 35 drives the clamping claw mounting shaft 36, the clamping claw cylinder 37 and the grabbing guide wheel 38 to move synchronously; the grabbing guide wheel 38 slides along the L-shaped guide groove 39, and when it moves to the turning position of the L-shaped guide groove 39, the eccentric setting of the grabbing guide wheel 38 drives the clamping claw mounting shaft 36 to rotate on the grabbing slide 35, thereby causing the clamping claw cylinder 37 to change from horizontal to vertical, until the clamping claw cylinder 37 moves to just above the pen refill on the transport mechanism 200; and then The cam drive 300 drives the grabbing mount 31 downward, which in turn drives the gripping cylinder 37 downward synchronously, allowing the gripping cylinder 37 to connect with the refill on the transport mechanism 200 and then clamp the refill. The cam drive 300, the grabbing cylinder 33, and the gripping cylinder 37 then cooperate to place the refill into the refill placement hole 22. Once the refill is placed in the refill placement hole 22, the first switch 12 drives the lifting push rod to disengage the stop block 23, allowing the stop pin 24 to extend into the corresponding refill placement hole 22 and connect with the refill, thereby retaining the refill in the refill placement hole 22. The wax sealing rotary table 1 then drives the refill fixture 2 to move the refill to the next station.
[0053] like Figure 9As shown, the first leveling assembly 10 includes a leveling fixing seat 101, a leveling cylinder 102 is installed on the leveling fixing seat 101, a first leveling mounting block 103 is provided on the output end of the leveling cylinder 102, the first leveling mounting block 103 is arranged above the refill fixture 2, and leveling push rods 104 are respectively provided at positions corresponding to the refill placement holes 22 on the first leveling mounting block 103. The leveling cylinder 102 can drive the leveling push rod 104 to connect or separate with the refill on the refill fixture 2. During processing, after the transport mechanism 200 transports the refill holder 2 containing the refill to the corresponding position of the first leveling assembly 10, the first switch 12 aligned with the first leveling assembly 10 first drives the limit pin 24 on the refill holder 2 to extend out of the refill placement slot and contact the refill limiter. The leveling cylinder 102 then drives the first leveling mounting block 103 downward, driving the leveling push rod 104 to descend synchronously. During the descent, the leveling push rod 104 contacts the upper end of the refill on the refill holder 2. As the leveling push rod 104 continues to descend, it pushes the refill to slide downward on the refill holder 2. The push of the leveling push rod 104 ensures that the upper end surfaces of all the refills on the refill holder 2 are aligned, and the upper ends of the refills are evenly leveled. Then, the first switch 12 is used to drive the lifting push rod to disengage the stop block 23, so that the stop pin 24 extends into the corresponding refill placement hole 22 and contacts the refill, thereby limiting the refill in the refill placement hole 22. Then, the wax sealing rotary table 1 drives the refill fixture 2 to move the refill to the processing position of the second leveling assembly 11.
[0054] like Figure 10As shown, the second leveling assembly 11 includes a second leveling mounting block 111, which is connected to the cam driving device 300. The second leveling mounting block 111 is arranged below the refill fixture 2, and a leveling groove 112 is provided on the upper end surface of the second leveling mounting block 111. The cam driving device 300 can drive the leveling groove 112 to connect or separate with the refill on the refill fixture 2; in this embodiment, the leveling groove 112 is V-shaped, so as to facilitate leveling and regularizing the lower end of the refill. During processing, after the wax sealing rotary table 1 transports the refill fixture 2 with the refill placed thereon to the corresponding position of the second leveling assembly 11, the second switch 13 is first used to drive the lateral push rod to move horizontally, so that the lateral push rod pushes the limit block 23 to rotate and swing along the pin, so that the limit pin 24 extends out of the corresponding refill placement hole 22, thereby contacting the limit of each refill in the refill placement hole 22; then the cam driving device 300 is used to drive the second leveling mounting block 111 to rise until the leveling grooves 112 are respectively connected with the lower ends of the refills on the refill fixture 2, as the second leveling mounting block 111 continues to rise, the leveling grooves 112 will push the refills to slide upward in the refill placement hole 22, so that the lower end surfaces of all the refills in the refill fixture 2 are on the same horizontal plane, and the lower ends of the refills are neatly leveled. Then, the second switch 13 is used to drive the transverse push rod to disengage the stop block 23, so that the stop pin 24 extends into the corresponding refill placement hole 22 and connects with the refill, thereby retaining the refill in the refill placement hole 22. Then, the wax sealing rotary table 1 drives the refill fixture 2 to move the refill to the processing position of the wax sealing assembly 4.
[0055] like Figure 11 As shown, the wax sealing assembly 4 includes a wax box 41 and a wax removal assembly. The wax box 41 is used to hold wax oil and is detachably connected to the machine 100 to facilitate the addition of wax oil. The wax box 41 is equipped with a heating device to prevent the wax oil from solidifying during processing. The wax removal assembly includes a wax removal block 42, which is connected to a cam drive 300. The cam drive 300 can drive the wax removal block 42 to move up and down. The wax removal block 42 is provided with wax holding grooves 43 at positions corresponding to the refill placement holes 22. During processing, the cam drive 300 drives the wax removal block 42 downward, allowing the wax trough 43 to extend into the wax box 41, and the wax in the wax box 41 flows into the wax trough 43. The cam drive 300 then drives the wax removal block upward, and the wax trough 43 is filled with wax until the wax trough 43 connects with the refill on the refill holder 2, and the refill's tip extends into the wax trough 43, thereby coating the tip with wax and sealing the refill. The cam drive 300 then drives the wax removal block 42 downward again, allowing the refill to extend out of the wax trough 43. The wax sealing rotary seat then drives the refill holder 2 to move the refill to the corresponding position of the air-drying component 5.
[0056] like Figure 1As shown, the air-drying assembly 5 includes a fan mount 51, which is fixedly connected to the machine 100. Multiple cooling fans 52 are mounted on the fan mount 51, capable of blowing air toward the refills in the refill holder 2. During operation, when the wax-sealing rotary seat drives the refill holder 2 and the refill to the corresponding position of the air-drying assembly 5, the cooling fans 52 blow air toward the refill holder 2, thereby rapidly solidifying the wax on the refill. The wax-sealing rotary seat then drives the refill holder 2 and the refill to the corresponding position of the refill. The first switch 12, aligned with the refill assembly 6, is then activated, causing the lifting rod to push the limit block 23 to rotate and swing along the latch, causing the limit pin 24 to extend out of the corresponding refill placement hole 22. The refill assembly 6 then grabs the wax-sealed refill from the refill holder 2 and places it on the unloading mechanism 7.
[0057] In this embodiment, the structure of the material taking component 6 is the same as that of the grabbing component 3, and the specific structure of the material taking component 6 will not be described in detail herein.
[0058] like Figure 1 As shown, the unloading mechanism 7 includes a unloading conveyor belt 71. The picking assembly 6 can grab the pen refills from the pen refill fixture 2 and place them on the unloading conveyor belt 71. The end of the unloading conveyor belt 71 away from the picking assembly 6 is provided with a receiving box 72. The unloading conveyor belt 71 is used to convey the processed pen refills to the receiving box 72. During processing, after the picking assembly 6 places the pen refills on the unloading conveyor belt 71, the unloading conveyor belt 71 is controlled to operate to convey the wax-sealed pen refills to the receiving box 72, and the processed pen refills are collected by the receiving box 72.
[0059] The automatic wax sealing device for pen refills can automatically wipe the pen refill tips on the material transport mechanism 200 through the pen tip wiping mechanism, removing ink and other dirt on the pen tips, allowing the wax sealing mechanism to better seal the pen tips, thereby improving the yield rate of processing. After wiping the pen tips, the material transport mechanism 200 transports them to the corresponding position of the gripping assembly 3. Through the operation of various components in the wax sealing mechanism, multiple pen refills can be leveled, waxed, air-dried, and unloaded. The entire processing process does not require human intervention, greatly improving the degree of automation of the equipment. Waxing multiple pen tips at a time can improve processing efficiency.

The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
