Description

Technical Field

[0001] This utility model relates to the field of pencil metal cap processing technology, specifically to an integrated machine for automatically assembling pencil metal caps. Background Technology

[0002] Pencil leads are made of either natural graphite or synthetic graphite. Natural graphite, being as soft as lead and prone to breakage during use, requires a metal cap encasing it in a surrounding wooden structure for protection. This metal cap also protects the lead from external impacts and pressure, ensuring the pencil's longevity and stability. Furthermore, the metal cap helps distribute pressure more evenly, reducing the likelihood of bending or deformation. During pencil manufacturing, an automated one-piece molding machine can be used to attach the metal cap to the pencil. However, existing technologies have the following problems:

[0003] The existing automatic pencil capping machine inserts pencils one by one into the metal cap, and the pencils fall into the collection box via the conveyor mechanism. However, due to the simple structure of the collection box, the pencils tend to accumulate on one side as they fall, requiring manual re-spreading of the pencils in the collection box, which is inconvenient. In addition, because there are a large number of pencils to be collected, the collection box is generally quite deep, which causes the pencils that have just been capped to fall from a high height, potentially causing the fragile lead to break and resulting in some loss. Utility Model Content

[0004] This utility model provides an integrated machine for automatically assembling metal caps for pencils, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An integrated machine for automatically assembling metal caps for pencils includes a processing platform. A pencil storage mechanism is provided on the left side of the processing platform. The pencil storage mechanism includes a storage box, and the inner cavity of the storage box contains a storage compartment. A mounting base plate is provided at the bottom of the storage compartment. A feeding ramp is movably installed on the upper right side between the front and rear sides of the inner wall of the storage compartment. The feeding ramp is located on the upper right side of the top of the storage compartment. A servo motor is fixedly installed on the bottom right side of the inner wall of the storage compartment. A turntable is fixedly installed on the output shaft of the servo motor. A connecting rod is movably installed at the eccentric top of the turntable.

[0009] A further improvement of this utility model is that: a reciprocating adjustment mechanism, a metal cap output mechanism, and a metal cap reciprocating installation mechanism are fixedly installed on the top rear side of the processing platform. The reciprocating adjustment mechanism is located on the right side of the metal cap reciprocating installation mechanism, and the metal cap output mechanism is located on the left side of the metal cap reciprocating installation mechanism. The output end of the metal cap output mechanism is fixedly connected to a metal cap feeding pipe, and the other end of the metal cap feeding pipe is located on the front side of the metal cap reciprocating installation mechanism.

[0010] A further improvement of this utility model is that: a lifting handle is fixedly installed on the upper left and right sides of the inner wall of the storage box; a docking plate is fixedly installed at the bottom center of the storage box; limit blocks are fixedly installed on the front and rear sides of the docking plate; a docking groove is opened at the top center of the mounting base plate; limit grooves extending to the top of the mounting base plate are opened on the front and rear sides of the docking groove; the docking plate is engaged with the docking groove; and the two limit blocks are engaged with the two limit grooves respectively.

[0011] A further improvement of this utility model is that: a lifting groove penetrating the inner cavity is provided on the left side of the storage box; an extension plate is fixedly installed on the lower left side of the storage box; a threaded rod is movably installed on the top of the extension plate; a knob is fixedly installed on the top of the threaded rod; a lifting block is threadedly installed on the outer wall of the threaded rod; the lifting block is slidably connected to the lifting groove; the right end of the lifting block penetrates into the inner cavity of the storage box and a pencil placement plate is fixedly installed thereon; and the four sides of the pencil placement plate overlap with the four sides of the inner wall of the storage box.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand

[0022] Understood. The present invention will now be further described in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides an integrated machine for automatically assembling metal pencil caps, including a processing platform 1. A pencil storage mechanism 2 is provided on the left side of the processing platform 1. The pencil storage mechanism 2 includes a storage box 21, and a storage compartment 22 is provided inside the storage box 21. A mounting base plate 24 is provided at the bottom of the storage compartment 22. A feeding inclined plate 23 is movably installed on the upper right side between the front and rear sides of the inner wall of the storage compartment 21. The feeding inclined plate 23 is located on the upper right side of the top of the storage compartment 22. A servo motor 211 is fixedly installed on the bottom right side of the inner wall of the storage box 21. The output shaft of 1 is fixedly mounted with a turntable 212. A connecting rod 213 is movably mounted at the top eccentric part of the turntable 212. A sliding plate 215 is movably mounted at the right end of the connecting rod 213. Two limiting sliding rods 214 are fixedly mounted between the left and right sides of the inner wall of the storage box 21. The sliding plate 215 is slidably connected to the two limiting sliding rods 214. The top of the sliding plate 215 is fixedly connected to the bottom of the mounting base plate 24. Telescopic elastic bands 241 are fixedly mounted on both the left and right sides of the mounting base plate 24. The other ends of the two telescopic elastic bands 241 are fixedly connected to the left and right sides of the inner wall of the storage box 21, respectively.

[0024] The servo motor 211 drives the turntable 212 to rotate, thereby using the movable connection between the connecting rod 213 at the top eccentric part of the turntable 212 and the slide plate 215 to make the slide plate 215 reciprocate left and right on the outer wall of the two limit slide rods 214. The fixed connection between the mounting base plate 24 and the top of the slide plate 215 drives the entire mounting base plate 24 and the storage box 22 on the top of the mounting base plate 24 to oscillate left and right, so that the pencils falling into the storage box 22 are always laid flat. At the same time, the two elastic bands 241 can shield the structure below while ensuring the normal left and right movement of the mounting base plate 24, preventing dust and foreign objects from entering.

[0025] like Figure 3 As shown, a feeding device 3 is fixedly installed on the top right side of the processing platform 1. A pencil conveying mechanism 4 is set on the top of the processing platform 1. The pencil conveying mechanism 4 is located to the left of the feeding device 3. The top of the pencil conveying mechanism 4 is located on the top right side of the storage box 21. A reciprocating adjustment mechanism 5, a metal cap output mechanism 6, and a metal cap reciprocating installation mechanism 7 are fixedly installed on the top rear side of the processing platform 1. The reciprocating adjustment mechanism 5 is located to the right of the metal cap reciprocating installation mechanism 7. The metal cap output mechanism 6 is located to the left of the metal cap reciprocating installation mechanism 7. It can automatically convey unidirectional metal caps through vibration frequency. The output end of the metal cap output mechanism 6 is fixedly connected to a metal cap feeding pipe 8. The other end of the metal cap feeding pipe 8 is located in front of the metal cap reciprocating installation mechanism 7.

[0026] By placing pencils without metal caps in the feeding device 3 and gradually lowering them, the pencils fall one by one onto the pencil conveying mechanism 4 and are conveyed to the right. During the conveying process, the reciprocating positioning mechanism 5 pushes the pencils forward and backward to ensure that the position of each pencil is consistent. After continuing to convey to the right, when the pencils pass the metal cap reciprocating installation mechanism 7, a large number of metal caps are conveyed to the front of the metal cap reciprocating installation mechanism 7 through the metal cap feeding pipe 8 by the rotating metal cap output mechanism 6. The metal cap reciprocating installation mechanism 7 then inserts the metal caps into the tail end of the pencil, so that the openings of the metal caps are automatically aligned in the same direction to achieve automatic assembly. The pencils with metal caps can then slide one by one into the storage box 21.

[0027] The metal cap output mechanism 6 and the metal cap reciprocating installation mechanism 7 are existing technologies and will not be described in detail.

[0028] like Figure 4 , Figure 5 As shown, a lifting handle 223 is fixedly installed on the upper left and right sides of the inner wall of the storage box 22. A docking plate 221 is fixedly installed at the center of the bottom of the storage box 22. Limiting blocks 222 are fixedly installed on the front and back sides of the docking plate 221. A docking groove 242 is opened at the center of the top of the mounting base plate 24. Limiting grooves 243 extending to the top of the mounting base plate 24 are opened on the front and back sides of the docking groove 242. The docking plate 221 is engaged with the docking groove 242. The two limiting blocks 222 are engaged with the two limiting grooves 243 respectively. A handle 223 is opened on the left side of the storage box 22. A lifting slide 224 runs through the inner cavity of the storage box 22. An extension plate 225 is fixedly installed on the lower left side of the storage box 22. A threaded rod 226 is movably installed on the top of the extension plate 225. A knob 227 is fixedly installed on the top of the threaded rod 226. A lifting block 228 is threaded on the outer wall of the threaded rod 226. The lifting block 228 is slidably connected to the lifting slide 224. The right end of the lifting block 228 extends through the inner cavity of the storage box 22 and a pencil placement plate 229 is fixedly installed thereon. The four sides of the pencil placement plate 229 overlap with the four sides of the inner wall of the storage box 22.

[0029] When removing the storage box 22, simply reverse the feeding ramp 23 to the right, and then use the two lifting handles 223 to lift the storage box 22 upwards. This will allow for easy removal of the pencils collected inside. During installation, align the bottom of the storage box 22 with the two mating plates 221, and insert it into the mating grooves 242 on the top of the mounting base plate 24 and the limiting grooves 243 on the front and rear sides of the inner ring of the mating grooves 242. This will complete the installation of the storage box 22. When initially installing and collecting the metal caps of the pencils, the storage box 22... The pencil placement plate 229 inside the storage box 22 is located at a relatively high position inside the cavity of the storage box 22. This allows the pencils that slide down into the storage box 22 after passing through the feeding inclined plate 23 to be lower than the pencil placement plate 229, thus effectively preventing the pencil leads from breaking. When the pencils laid out on the pencil placement plate 229 are about to overflow the storage box 22, the knob 227 can be rotated to rotate the threaded rod 226 at the top of the extension plate 225. The threaded connection between the threaded rod 226 and the lifting block 228 drives the entire pencil placement plate 229 to descend, so that more pencils can be collected.

[0030] The working principle of this all-in-one machine that automatically assembles pencil caps will be explained in detail below.

[0031] like Figure 1-5As shown, pencils without metal caps are placed in the feeding device 3 and gradually lowered, causing them to fall one by one onto the pencil conveying mechanism 4 and be conveyed to the right. During the conveying process, the reciprocating positioning mechanism 5 pushes the pencils forward and backward to ensure that each pencil is in the same position. After continuing to be conveyed to the right, when the pencils pass the metal cap reciprocating installation mechanism 7, a large number of metal caps are conveyed to the front of the metal cap reciprocating installation mechanism 7 through the metal cap feeding pipe 8 by the rotating metal cap output mechanism 6. The metal cap reciprocating installation mechanism 7 then inserts the metal caps into the ends of the pencils. The pencils with metal caps can then pass one by one through the feeding device. As the pencil 23 falls into the storage box 22, the servo motor 211 drives the turntable 212 to rotate. This, in turn, utilizes the movable connection between the connecting rod 213 at the eccentric top of the turntable 212 and the sliding plate 215 to cause the sliding plate 215 to reciprocate left and right along the outer wall of the two limiting rods 214. The fixed connection between the mounting base plate 24 and the top of the sliding plate 215 causes the entire mounting base plate 24 and the storage box 22 on top of the mounting base plate 24 to oscillate left and right, ensuring that the pencils inside the storage box 22 remain flat. Simultaneously, two elastic bands 241 ensure the normal left and right movement of the mounting base plate 24. The lower structure is shielded to prevent dust and foreign objects from entering. When removing the storage box 22, simply reverse the sliding plate 23 to the right, then use the two lifting handles 223 to lift the storage box 22 upwards. This allows for easy removal of the pencils collected inside. During installation, align the bottom of the storage box 22 with the two mating plates 221, fitting them into the mating grooves 242 on the top of the mounting base plate 24 and the limiting grooves 243 on the front and rear sides of the inner ring of the mating grooves 242. This completes the installation of the storage box 22. When initially removing the metal caps from the pencils... During installation and collection, the pencil placement plate 229 inside the storage box 22 is located at a relatively high position within the inner cavity of the storage box 22. This ensures that the pencils that slide down into the storage box 22 via the feeding ramp 23 are at a lower height than the pencil placement plate 229, effectively preventing the pencil leads from breaking. When the pencils laid out on the pencil placement plate 229 are almost overflowing the storage box 22, the knob 227 can be rotated to rotate the threaded rod 226 at the top of the extension plate 225. The threaded connection between the threaded rod 226 and the lifting block 228 drives the entire pencil placement plate 229 to descend, allowing more pencils to be collected.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
