Description

Technical Field

[0001] The utility model belongs to the technical field of pencil processing devices, in particular to a continuous grooving device for pencil processing. Background Art

[0002] Pencils are a type of pen used for writing and sketching, with a history spanning over 400 years. Pencil barrels can be made of materials such as wood, paper, and plastic, while the lead is primarily composed of graphite and clay. Pencils come in a wide variety of styles, including those with wooden barrels, sharpened barrels, and capped pencils. The advent of capped pencils addresses several issues with traditional pencils, such as unsanitary conditions, easily broken tips, and portability. Pencil hardness is indicated by "H" and "B," with "H" representing hardness and "B" representing blackness, with higher numbers indicating higher hardness or blackness. The pencil manufacturing process involves mixing graphite and clay, extruding, drying by heating, and firing the material. Finally, the lead is impregnated with oil to form the lead, which is then assembled with the barrel. The barrel can be made of materials such as wood and plastic, and the manufacturing process includes molding, offset printing, and assembly. The Hole Pencil is a learning tool designed specifically for children. It incorporates ergonomic principles and environmentally friendly materials to help children develop proper pen-holding posture, improve writing and drawing skills, and ensure their safety and health. A hole pen is a pencil with a pen body of an equilateral triangle or a regular hexagon and an elliptical groove on the pen body (specifically, Figure 1 When producing a hole pen, it is necessary to open an elliptical groove on each surface of the pen body, which is a regular triangle or a regular hexagon. The existing grooving device can only groove one side, and multiple surfaces of the pen body need to be turned over before grooving, which makes the production efficiency relatively low.

[0022] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present invention but are not intended to limit the scope of the present invention. All other embodiments obtained by persons of ordinary skill in the art without creative effort are intended to fall within the scope of protection of the present invention.

[0023] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a continuous grooving device for processing pencils is used to groove multiple surfaces of pencils to produce pendant pens 7. The device comprises a workbench 1, mounted on a conveyor belt 2. The conveyor belt 2 is equipped with a loading mechanism 3, a continuous grooving device 4, a wood chip collection mechanism 5, and a discharge mechanism 6. The loading mechanism 3 is used to convey pencils to be processed one by one onto the conveyor belt 2. The continuous grooving device 4 is used to groove multiple surfaces of pencils conveyed on the conveyor belt 2 to produce pendant pens 7. The wood chip collection mechanism 5 is used to collect wood chips generated by the continuous grooving device 4 during grooving. The discharge mechanism 6 is used to remove pendant pens 7 from the conveyor belt 2 after grooving by the continuous grooving device 4. Specifically, the continuous grooving device for processing pencils is designed to significantly improve the production efficiency and processing quality of pendant pens 7. The workbench 1 is the basic support structure of the entire processing device and is made of a sturdy and durable metal material such as stainless steel or aluminum alloy to ensure long-term stability and load-bearing capacity. The workbench 1 is also equipped with necessary electrical control systems and safety features, such as an emergency stop button and a protective cover, to ensure safe production. The conveyor belt 2 is made of high-strength, wear-resistant rubber or PVC material with excellent tensile and corrosion resistance, capable of maintaining a stable conveying speed during continuous operation. Its width and speed can be adjusted to suit different pencil models and processing requirements to ensure stable and accurate pencil conveying. Guide plates are installed on both sides of the conveyor belt 2 to prevent pencils from shifting or falling during conveyance. The loading mechanism 3 is designed with automatic sorting and positioning functions. It automatically removes pencils to be processed from the storage hopper and places them at the starting position of the conveyor belt 2 using auxiliary equipment such as a robotic arm or vibrating plate. The continuous grooving device 4 consists of multiple high-precision cutting tools arranged according to a preset pattern and depth, capable of simultaneously or sequentially grooving multiple surfaces of the pencil. Driven by a motor, the tool assembly achieves high-speed rotation and precise feed, ensuring uniform and consistent grooving. The sawdust collection mechanism 5, located below the continuous slotting device 4, utilizes a highly efficient dust collection and filtration system to rapidly absorb and collect sawdust and dust generated during the slotting process. The unloading mechanism 6 is responsible for safely and orderly removing the finished pencils 7 from the conveyor belt 2. It automatically adjusts the unloading speed based on the number of pencils processed, ensuring that each pencil smoothly and accurately enters the next process. Furthermore, the unloading mechanism 6 is equipped with quality inspection devices, such as a visual recognition system, to monitor the quality of the finished product, ensuring that only qualified pencils 7 enter the next stage. This continuous slotting device for pencil processing, through its highly automated design and sophisticated manufacturing process, achieves efficient, precise, and environmentally friendly pencil processing, significantly improving the production efficiency and quality of pencils.

[0024] Combine Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the continuous slotting device 4 includes a mounting frame 41 mounted on the workbench 1. The mounting frame 41 is equipped with a pencil body clamping and flipping mechanism 42 and a pencil body slotting mechanism 43. The pencil body clamping and flipping mechanism 42 is used to securely hold pencils on the conveyor belt 2 and flip the processed surface of the pencils. The pencil body slotting mechanism 43 slots the processed surface of each pencil flipped by the clamping and flipping mechanism 42, thereby forming a hole-shaped pencil 7. Specifically, the continuous slotting device 4 is crucial to the quality and production efficiency of the final product—the hole-shaped pencil 7. The mounting frame 41 serves as a stable support platform for the pencil body clamping and flipping mechanism 42 and the pencil body slotting mechanism 43. It is welded from high-quality steel to ensure structural stability and load-bearing capacity. The pencil body clamping and flipping mechanism 42 is a key component that ensures stable and precise positioning of the pencils during processing. It primarily consists of a clamping device, a flipping drive device, and a control system. The clamping device uses pneumatic or electric grippers that gently yet firmly grip the pencils, preventing slippage or damage during processing. The flipping drive device automatically flips the pencil's processed surface through a motor, reducer, and transmission mechanism, ensuring uniform groove processing on each surface. The control system receives commands from the workbench 1 or an external controller, precisely controlling the timing and angle of the clamping and flipping movements. The pencil body slotting mechanism 43 is the core component for performing the slotting process and is designed for precision and efficiency. It primarily consists of a tool assembly, a feed system, and a control system. The tool assembly comprises multiple precision-machined tools, arranged on a tool holder according to a preset pattern and depth, capable of slotting different surfaces of a pencil simultaneously or sequentially. The feed system, driven by a motor, lead screw, or pneumatic cylinder, precisely feeds the tool assembly to the pencil, ensuring the groove depth and width meet the design requirements. The control system coordinates parameters such as the tool assembly's motion trajectory, feed speed, and processing time to achieve efficient and precise processing results. In actual operation, the pencil body clamping and flipping mechanism 42 first secures the pencil on the conveyor belt 2 and adjusts its position according to processing requirements. Subsequently, the pencil body slotting mechanism 43 activates and slots the current processing surface of the pencil. After processing one surface, the pencil body clamping and flipping mechanism 42 flips the pencil to the next processing surface, where the pencil body slotting mechanism 43 processes the surface again. This cycle continues until all the pencil's intended processing surfaces have been slotted. Throughout this process, the sawdust collection mechanism 5 operates synchronously to collect and dispose of sawdust and dust generated during processing, maintaining a clean and hygienic working environment. Finally, the finished hole pencil 7 is removed from the conveyor belt 2 by the unloading mechanism 6 and enters subsequent quality inspection, packaging, and other processes.

[0025] Combine Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, the pen body clamping and flipping mechanism 42 includes sliding blocks 421 arranged opposite to each other on both sides of the mounting frame 41, a first servo motor 422 is arranged on the sliding block 421, the output end of the first servo motor 422 is fixedly connected to a clamping block 423, and the two oppositely arranged clamping blocks 423 are provided with grooves 424 matching the two ends of the pencil. Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, sliders 4211 are installed on either side of the sliding block 421. A second servo motor 425 is installed at the bottom of the sliding block 421. Slide slots 411 are provided on both sides of the mounting frame 41 to match the sliders 4211. The sliding block 421 is connected to the mounting frame 41 by the second servo motor 425 to slide up and down on both sides of the mounting frame 41. Specifically, the pencil body clamping and flipping mechanism 42 ensures stable clamping and flexible flipping of the pencil during processing. The sliding blocks 421, as the foundational components of the clamping and flipping mechanism, are installed on both sides of the mounting frame 41, forming a relatively stable support structure. Each sliding block 421 is equipped with a first servo motor 422, which can precisely control the rotation angle and speed of the output shaft. The output end of the first servo motor 422 is secured to the clamping block 423 via a sturdy coupling or direct connection, ensuring accurate and stable power transmission. The two opposing clamping blocks 423 are designed with grooves 424 that match the ends of the pencil. These grooves 424 are not only precisely shaped, but also made of soft material (such as rubber or silicone), which can provide sufficient friction during the clamping process to prevent the pencil from slipping while avoiding damage to the pencil surface. In order to achieve the flexible movement of the sliding block 421 on the mounting frame 41, sliders 4211 are provided on both sides of the sliding block 421. At the same time, chute 411 that matches the slider 4211 is opened inside the two sides of the mounting frame 41. The design of the chute 411 not only takes into account the smoothness of sliding, but also ensures the stability and precision of sliding. Through the precise fit between the slider 4211 and the chute 411, the sliding block 421 can achieve precise up and down sliding on the mounting frame 41. In order to achieve the up and down sliding of the sliding block 421, the bottom of each sliding block 421 is equipped with a second servo motor 425. The second servo motor 425 is connected to the sliding block 421 through a gear, a screw or other transmission mechanism, and can accurately control the up and down movement distance and speed of the sliding block 421. During the processing, the second servo motor 425 drives the sliding block 421 to move up and down according to the instructions of the control system, thereby driving the clamping block 423 and the pencil to move to the predetermined processing position. When the pencil is transferred to the specified position, the first servo motor 422 is started, driving the clamping blocks 423 to move closer to each other until the pencil is firmly clamped in the groove 424. Subsequently, the second servo motor 425 drives the sliding block 421 to slide up and down according to the processing requirements, moving the pencil to the bottom of the pen body slotting mechanism 43 for processing. After completing the processing of one side, the second servo motor 425 drives the sliding block 421 to move to the flipping position again. At this time, the pencil can be flipped by other mechanisms (such as a flip cylinder or flip arm) so that the next processing surface can be slotted. The entire clamping and flipping process is precisely controlled by the control system, ensuring the efficiency and accuracy of the processing.

[0026] Combine Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the pen body slotting mechanism 43 includes a third servo motor 431 mounted on one side of the top of the mounting frame 41. The output end of the third servo motor 431 is fixedly connected to a rotating shaft 432, on which a slotting roller 433 is mounted. Several slotting blades 434 are mounted on the surface of the slotting roller 433. Specifically, the pen body slotting mechanism 43 determines the slotting quality and production efficiency of the pen 7. The third servo motor 431 is mounted on one side of the top of the mounting frame 41 and provides a reliable power source for the rotation of the slotting roller 433. Through a preset program or external control signals, the third servo motor 431 can precisely control the speed, rotation angle, and start and stop times of the rotating shaft 432, thereby achieving fine-tuning of the slotting process. As the key component connecting the third servo motor 431 and the slotting roller 433, the rotating shaft 432 is designed for stability and transmission efficiency. The rotating shaft 432 and the output end of the third servo motor 431 are secured via a coupling or direct connection, reducing energy loss and vibration during power transmission. The groove roller 433 is a key executive component in the pencil body groove mechanism 43, and its design directly affects the effect and quality of the grooves. The groove roller 433 is made of wear-resistant and corrosion-resistant materials, and its surface is specially treated to increase its hardness and smoothness. Several groove blades 434 are evenly distributed on the surface of the groove roller 433. The shape, angle, and distribution density of the groove blades 434 have been carefully calculated and optimized to enable efficient and uniform groove processing on the pencil surface during rotation. The groove blades 434 are the part of the groove roller 433 that is directly involved in the processing, and their quality directly determines the accuracy and effect of the grooves. Each groove blade 434 is finely ground and polished to ensure the sharpness of the cutting edge and the surface finish. The groove blades 434 are typically arranged in a spiral or staggered manner to reduce vibration and noise during processing and improve the uniformity and consistency of the grooves. The pen body slotting mechanism 43 realizes efficient, uniform and precise slotting of the pencil surface through the precise control of the third servo motor 431, the stable support and transmission of the rotating shaft 432, the design of the slotting roller 433 and the fine processing and arrangement of the slotting blade 434, thereby providing a strong guarantee for the manufacture of the hole pen 7.

[0027] Combine Figure 2 、 Figure 3 and Figure 4As shown, the loading mechanism 3 comprises a material bin 31 mounted on the workbench 1. A feed inlet 32 ​​is located at the top of the bin 31, and a discharge outlet 33 is located at the bottom. Specifically, the loading mechanism 3 is responsible for orderly and automatically transporting pencils to be processed from storage to the processing flow. As the main component of the loading mechanism 3, the bin 31 takes into account storage efficiency, convenient material retrieval, and space utilization. The shape and size of the bin 31 are customized according to the specifications of the pencils and the processing volume to maximize the capacity of the pencils to be processed. The top of the bin 31 is equipped with a feed inlet 32, which is the only access point for pencils to enter the bin. The design of the feed inlet 32 ​​takes into account smooth feeding and ease of operation. It is typically designed as a sufficiently large opening and equipped with appropriate guide devices, such as inclined slides or baffles, to guide the pencils smoothly into the bin. The bottom of the bin 31 is equipped with a discharge outlet 33, which ensures that the pencils can be discharged from the bin 31 one by one and in an orderly manner. To improve the automation and processing efficiency of the feeding mechanism 3, advanced control systems and sensor technologies can be introduced. For example, a level sensor can be installed in the material bin 31 to monitor the number of pencils in the bin in real time and automatically adjust the feed and discharge speeds based on processing requirements. A timer or counter can also be provided to precisely control the quantity and time interval of each discharge, ensuring a continuous and stable supply of pencils. Furthermore, to further enhance the intelligence of the feeding mechanism 3, it can be integrated with the control system of the entire processing device. By collaborating with other mechanisms (such as the pencil body clamping and flipping mechanism 42 and the pencil body slotting mechanism 43), automated control and optimization of the processing flow can be achieved. For example, when the feeding mechanism 3 detects a shortage of pencils in the bin, it can automatically send a signal to the control system requesting that processing be suspended and refilled. Once the processing device completes processing a batch of pencils, it can automatically send a signal to the feeding mechanism 3 requesting that discharge be resumed for the next batch.

[0028] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the sawdust collection mechanism 5 comprises a sawdust collection frame 51 positioned below the continuous slotting device 4. Within the sawdust collection frame 51 is a retractable sawdust collection box 52, with a handle 53 on one side of the sawdust collection box 52. Specifically, the sawdust collection mechanism 5 is designed to effectively collect and dispose of sawdust and dust generated during the pencil slotting process, maintaining a clean and hygienic work environment while protecting the health and safety of operators. The sawdust collection frame 51 is securely mounted below the continuous slotting device 4, its position ensuring maximum capture of sawdust and dust scattered from the processing area. The collection frame 51 is constructed of durable materials, such as stainless steel or heavy-duty plastic, to withstand the weight of the sawdust and potential impacts. The sawdust collection box 52, the actual component that carries and stores the sawdust, is designed with convenience and durability in mind. The ample interior space of the sawdust collection box 52 can accommodate a large amount of sawdust, reducing the need for frequent replacement and cleaning. A handle 53 is provided on one side of the sawdust collection box 52 for operator convenience. When the collection box needs to be cleaned or replaced, the operator only needs to gently pull the handle 53 to pull the collection box 52 out of the collection frame 51 without the need to move or disassemble other components.

[0029] Combine Figure 2 、 Figure 3 and Figure 4As shown, the unloading mechanism 6 includes a pencil collection frame 61 located at the end of the conveyor belt 2. Within this frame 61 is a retractable pencil collection box 62. Specifically, the unloading mechanism 6's primary function is to accurately and orderly collect the slotted pencils from the conveyor belt 2 for subsequent packaging, inspection, or further processing. The pencil collection box 61, positioned at the end of the conveyor belt 2, ensures that the pencils can slide smoothly into the frame 61 after completing the processing process. The shape and size of the frame 61 are customized based on the specifications and processing volume of the pencils to maximize space utilization and facilitate collection. The opening of the frame 61 tightly mates with the end of the conveyor belt 2, creating a smooth transition and minimizing the risk of pencils getting stuck or damaged during their sliding. Guide plates or cushioning pads can also be designed around the edges of the frame 61 to further guide the pencils and protect their surfaces from damage. As the component that actually holds the processed pencils, the frame 62 is designed with convenience and practicality in mind. The pencil collection box 62 is made of a lightweight yet durable material, such as plastic or a metal mesh, allowing for easy removal and transport once filled with pencils. Its interior is divided according to the size and quantity of the pencils, ensuring orderly arrangement and stable storage within the box. To facilitate operator use, the pencil collection box 62 is designed to be retractable, connected to the pencil collection frame 61 via slides or rollers. With a simple pull, the operator can remove the filled pencil collection box 62 from the pencil collection frame 61 without the hassle of moving or disassembling other components.
