[0012] Beneficial effects

[0013] This invention provides an automatic pencil shaping and wire drawing device. Compared with the prior art, it has the following advantages:

[0014] Firstly, this utility model achieves fully automated production of pencils from material feeding to finished product output without human intervention. In the feeding stage, the feeding hopper automatically rotates the pencils into the feeding wheel through angle optimization, eliminating the need for manual placement of each pencil. In the shaping stage, the nylon feeding wheel feeds pencils at a uniform speed and quantity through precise pencil slots. Combined with the frictional rotation of the conveyor belt and the feeding wheel, this ensures that each pencil has a uniform shaping standard, replacing manual positioning and rotation operations. In the transfer stage, the equidistant conveyor belt automatically measures and precisely connects to the automatic pencil clamp. The automatic pencil clamp uses pneumatic control to automatically clamp and transfer pencils in batches, eliminating the need for manual handling and clamping. In the wire drawing stage, the automatic pencil clamp automatically enters the reciprocating wire drawing machine along the track. The wire drawing machine automatically adjusts parameters according to the pencil length, and the pencil clamp rotates automatically according to the settings to ensure uniform wire drawing, eliminating the need for manual angle adjustment or force control throughout the process. In the unloading stage, after wire drawing is completed, the pencil clamp automatically ejects the pencils to the receiving hopper, achieving continuous production. By integrating the shaping and wire drawing processes and automating the entire process, the reliance on manual labor is significantly reduced.

[0015] Secondly, the motor-driven mounting shaft of this utility model drives the movable belt and the actuating block to move, orderly guiding the pencils in the feeding hopper to the discharge trough. By actuating the pencils out of the discharge trough, blockage at the discharge point is prevented. Furthermore, the pencil feeding wheel can be disassembled and replaced with bolts, facilitating the maintenance or replacement of the pencil feeding wheel, adapting to the pencil clamping needs of different specifications of pencils, and improving the versatility of the equipment.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an automatic pencil surface shaping and wire drawing device, including a processing table body 1, on which a processing mechanism for pencil surface shaping is provided, the processing mechanism including:

[0023] The shaping component includes a feeding hopper 2 fixed at one end of the upper surface of the processing table body 1.

[0024] The wire drawing assembly includes a pen-clamping motor track 9 installed on the upper end of the processing table body 1 for driving the movement of the automatic pen clamper 8. One end of the pen-clamping motor track 9 is connected to the output end of the equidistant conveyor belt 7, and the other end of the pen-clamping motor track 9 is provided with a reciprocating wire drawing machine 10. The end of the processing table body 1 is provided with a receiving hopper 11.

[0025] In a preferred embodiment, the automatic pencil clamp 8 can hold nine pencils at a time. When the position of the pencil corresponds to the position of the automatic pencil clamp 8, the automatic pencil clamp 8 automatically opens and moves forward. The pencil enters the clamp and is automatically clamped at a distance of 10 mm. The pencil clamp motor track 9 is a linear track structure and is the moving path of the automatic pencil clamp 8. One end of the track is connected to the output end of the equidistant conveyor belt 7, and the other end extends to the working area of ​​the reciprocating wire drawing machine 10, forming a connecting channel through the two. The automatic pencil clamp 8 is mounted on the pencil clamp motor track 9 and can move along the length of the track. It can pick up materials at the position of the equidistant conveyor belt 7 and move into the reciprocating wire drawing machine 10 to complete the wire drawing operation.

[0026] In the shaping assembly, a worker puts a pencil into the feeding hopper 2, and it comes out from the discharge chute 201. The pencil enters the pencil slot on the outer wall of the feeding wheel 3. The feeding wheel 3 rotates and accurately delivers the pencil to the shaping cutter 4. The shaping cutter 4 shapes the end of the pencil. At the same time, the conveyor belt 5 transports the pencil to the next station. During the friction with the feeding wheel 3, the pencil rotates to ensure uniform shaping. After that, the pencil enters the storage bin 6, and then the equidistant conveyor belt 7 accurately measures the number of pencils and transports them to the position where they dock with the automatic pencil clamp 8.

[0027] Furthermore, when the pencil position corresponds to the position of the automatic pencil clamp 8, the automatic pencil clamp 8 automatically opens and moves forward, and the pencil is automatically clamped when it enters the clamp at a distance of 10 mm. The automatic pencil clamp 8 moves along the pencil clamping motor track 9 to the working area of ​​the reciprocating wire drawing machine 10. The reciprocating wire drawing machine 10 automatically clamps the pencil and performs wire drawing according to the set parameters. After each reciprocating motion, the automatic pencil clamp 8 rotates one-third of a turn. The pencil rotates a total of 3 turns to end the wire drawing process. After the wire drawing is completed, the automatic pencil clamp 8 continues to move forward along the pencil clamping motor track 9 and automatically ejects the pencil into the receiving hopper 11.

[0028] In a preferred embodiment, the shaping tool 4 is a custom-made tool that can shape the end of the pencil, and the storage bin 6 is made of stainless steel, which has the function of high smoothness and does not contaminate the pencil.

[0029] In a preferred embodiment, the drive assembly includes a pair of fixed plates 202 fixed to the upper surface of the discharge trough 201. The fixed plates 202 are provided with a pair of mounting shafts 203 driven by a motor. A movable belt 204 is provided between the mounting shafts 203. A toggle block 205 is fixedly connected to the outer wall of the movable belt 204. The motor drives the mounting shafts 203 to move the movable belt 204 and the toggle block 205, so as to orderly push the pencils in the feed hopper 2 to the discharge trough 201. By toggle the pencils out of the discharge trough 201, blockage at the discharge point is prevented.

[0030] In a preferred embodiment, a connecting shaft 1201 is rotatably connected to one end of the movable shaft body 12. The connecting shaft 1201 has a toothed groove 1202 inside. A locking shaft 1203, which is installed by bolts, is inserted into the groove 1202. The pen feed wheel 3 is located at one end of the locking shaft 1203. The movable shaft body 12 drives the pen feed wheel 3 to rotate through the connecting shaft 1201, the groove 1202 and the locking shaft 1203. The pen feed wheel 3 can be disassembled and replaced by bolts, which facilitates the maintenance or replacement of the pen feed wheel 3, adapts to the pen clamping needs of different specifications of pencils, and improves the versatility of the equipment.

[0031] Additional notes: The drive mounting shaft drives the movable belt and the toggle block to move, which is driven by a 24BYJ48 stepper motor. The movement of the automatic pen holder on the track is driven by a separate LMX1 motor.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, pencils are first fed into the feeding hopper 2 through the opening at the top of the equipment. The feeding hopper 2 can hold 1400 pencils and is designed with a reasonable angle to smoothly rotate the pencils into the feeding roller 3. The feeding roller 3 can be made of nylon as the main material. Through its precise pencil-holding groove, the pencils are rotated at a uniform speed and accurately delivered to the shaping cutter 4. The shaping cutter 4 shapes the ends of the pencils. The shaped pencils are then conveyed by the conveyor belt 5. The friction between the conveyor belt 5 and the feeding roller 3 causes the pencils to rotate, ensuring that the shaping of each pencil is uniform and standardized. Subsequently, the pencils are transported to the storage bin 6, and then conveyed to the automatic pencil clamp 8 by the equidistant conveyor belt 7. The equidistant conveyor belt 7 can accurately count the number of pencils and work with the automatic pencil clamp 8. The automatic pen clamp 8 precisely aligns with the pen holder; it clamps nine pens at a time. When the pen's position corresponds to the position of the automatic pen clamp 8, the automatic pen clamp 8 automatically opens and moves forward. The pen enters the clamp 10 mm from the end and is automatically clamped. After being picked up, the pen is driven by the motor to enter the reciprocating wire drawing machine 10 along the track. The reciprocating wire drawing machine 10 can automatically control the clamping force, and the forward and backward sliding distance can be adjusted according to the length of the product. One reciprocating motion is one cycle. At the same time, the pen clamp will rotate one-third of a turn after the wire drawing machine completes one cycle. Each pen rotates three times to end the wire drawing process. After the wire drawing is completed, the pen clamp moves towards the receiving hopper 11 and directly ejects the pen, which falls into the receiving hopper 11, completing the entire production process and realizing continuous production.
