Abstract
Description
Technical Field
[0001] This invention relates to the field of pencil board grooving machine technology, and more particularly to a pencil grooving board processing equipment. Background Technology
[0002] The pencil board grooving machine is a core piece of specialized equipment in the wooden pencil manufacturing production line. Its main function is to precisely mill one or more concave grooves into a flat pencil board (usually a wood chip that has been stained, dried, and wax-impregnated). These grooves, matching the shape and size of the pencil lead, act as a "lead bed," accommodating and securing the lead. The quality of the grooving directly determines many key performance indicators of the final pencil product; therefore, this equipment plays a crucial role in the pencil manufacturing industry.
[0003] In pencil manufacturing, a crucial step is wrapping and gluing two semi-finished pencil leads into a grooved wooden blank, forming a "pencil sandwich" structure. Therefore, precisely sized, uniformly deep, and smooth grooves on the pencil blank are essential for ensuring the quality of the finished pencil. Grooving with a pencil board grooving machine is a common method. These machines typically use multiple sets of high-speed rotating disc milling cutters to mill the uniformly fed blank into grooves. However, the milling cutters are prone to vibration during high-speed rotation and cutting, leading to chatter marks on the groove walls and poor surface finish. The high-speed milling process also generates a large amount of wood dust, which accumulates in the grooves of the grooving board. After being transported by conveyor belt, the dust in the grooves accumulates due to transport vibrations, affecting subsequent lead-filling processes. Therefore, a pencil grooving board processing device is needed to solve these problems. Summary of the Invention
[0004] The purpose of this invention is to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pencil slotted plate processing equipment includes a slotting device. The top right side of the slotting device is provided with a feeding part, and the top left side of the slotting device is provided with a slotting part. Both the feeding part and the left side of the slotting part are provided with a pressing part. An air blowing part is installed at the top of the slotting part. The feeding part ensures continuous supply of blank plates, the slotting part completes precise slotting, the pressing part ensures conveying stability, and the air blowing part cleans up dust in time, thereby improving the overall processing efficiency and product quality. The grooving equipment includes a support, a conveying module is set at the center of the support, and a through groove is opened on the surface of the support near the grooving part for the falling dust. A dust collection module for collecting dust is installed inside the through groove. A collection box for collecting dust is inserted into the side of the support. The support serves as the basic support of the equipment, the conveying module is responsible for the stable conveying of the blank plate, and the dust collection module and the collection box form a dust collection system. The through groove design allows the dust to fall naturally and be centrally processed, reducing environmental pollution and equipment maintenance frequency. The conveying module includes a conveying frame plate embedded in the central groove of the support. A conveyor belt assembly is installed inside the conveying frame plate. The conveyor belt assembly consists of a conveyor belt, a drive wheel, a balance wheel for support, and a servo motor end connected to the drive wheel shaft. The conveying frame plate limits and constrains the blank plate through side grooves and vertical plates to prevent displacement. The slotted part includes a semi-enclosed processing chamber fixed to the top of the support. The processing chamber is equipped with a cutting component for slotting. Two inner partitions are provided on both sides of the inner wall of the processing chamber, and a lower groove is provided between the inner partitions and the processing chamber. The bottom of the lower groove is connected to the through groove on the surface of the support.
[0006] Preferably, the long side of the conveyor plate has a side groove near the through groove of the support. The opening of the storage box covers the through groove at the bottom of the support. The storage box is provided with rails on the left and right sides, and the rails are slidably installed inside the support through the rail grooves. The side grooves facilitate the smooth entry of dust from the conveying area into the dust collection system. The storage box is slidably installed through the rails, which is convenient for disassembly and cleaning, and improves the convenience of equipment maintenance.
[0007] Preferably, the dust collection module includes two sets of sweeping wheels in the through slot of the rotating mounting support. One end of each sweeping wheel shaft passes through the support and is connected to a gear drive via a pulley set A. The ends of both gear shafts are rotatably mounted on the outer surface of the support. The two gears are meshed together by teeth. One gear shaft end passes through a cover plate and is connected to the shaft end of the drive motor A. The cover plate is fixed to the surface of the support by bolts and covers and protects the gears. The sweeping wheels pull the dust down to the collection box through relative rotation. The gears and pulley set A ensure that the two sweeping wheels operate synchronously. The drive motor A provides power. The cover plate protects the transmission components from dust contamination and extends the equipment life.
[0008] Preferably, the processing chamber is equipped with rubber curtains at the openings on both the left and right sides. The set of rubber curtains on the left side has two layers. The inner wall of the outer layer of the rubber curtain is provided with wiping rubber that is compatible with the cutting parts. The rubber curtains are sealed when the blank enters and exits the processing chamber to reduce dust escape. The wiping rubber in the double-layer design is specially used to clean the residual dust in the groove of the slot plate, further ensuring the cleanliness of the slot plate surface.
[0009] Preferably, the cutting component includes a beam frame fixed to the top of the processing chamber, with two threaded shafts inserted from top to bottom at the top of the beam frame. The bottom ends of the two threaded shafts pass through the processing chamber and are connected and fixed to a horizontal plate. The bottom of the horizontal plate is provided with two suspension plates, and a milling cutter disc assembly is rotatably mounted on the front of each suspension plate. The shaft end of one of the milling cutter disc assemblies passes through the suspension plate and is connected to the shaft end of the drive motor B. The drive motor B is fixed to the surface of the suspension plate by a support plate. The shaft ends of the two milling cutter disc assemblies are connected by a pulley assembly B. A piezoelectric ceramic actuator is installed on the side wall of the drive motor B. The threaded shafts and buffer springs allow the cutting component to be finely adjusted in height to adapt to blanks of different thicknesses. The double milling cutter disc assembly reduces vibration and chatter marks through a process of first slotting and then repairing the slots.
[0010] Preferably, the top end of the threaded shaft is fixed by multiple sets of nuts at the upper and lower ends of the beam frame. A buffer spring is sleeved on the surface of the threaded shaft, and the two ends of the buffer spring abut against the beam frame and the end face of the processing chamber, respectively. A through hole for a suction fan is reserved at the top of the processing chamber, and the through hole is normally sealed with a rubber plug. The nut fixing provides flexibility for height adjustment, and the buffer spring absorbs the impact force during the grooving process, protecting the equipment structure.
[0011] Preferably, the air blowing unit includes a bracket fixed to the bottom end of the beam frame crossbeam. A blower is installed at the top of the bracket, and an air pipe is provided at the air outlet end of the blower. The two branch pipe ends of the air pipe are connected and communicate with the cross arm air pipe. The cross arm air pipe is suspended and installed on the inner wall of the processing chamber. The blower generates high-pressure airflow, which forms a uniform air force coverage through the air pipe and the cross arm air pipe, quickly blowing the dust in the slotted area to the dust collection system, thus avoiding the adhesion of dust to the surface of the slot plate.
[0012] Preferably, the feeding section includes a hopper fixed to the support and the surface of the conveyor frame plate. The bottom left side of the hopper has a discharge opening. The top of the hopper is fitted with a beam cover, and a radial shaft is inserted through a through hole at the center of the top of the beam cover. The bottom end of the radial shaft is connected to a pressure cover, and a vibrator is installed on the surface of the pressure cover. The left and right sides of the beam cover are fixed by a clamping shaft. The clamping shaft consists of an insert shaft and a spring end sleeved on the surface of the insert shaft. The hopper stores blanks, and the pressure cover promotes smooth feeding of the blanks through the counterweight and the vibration force of the vibrator, preventing jamming.
[0013] Preferably, the pressing part includes a horizontal frame plate fixed to the left side of the processing chamber and the material hopper. Several movable arms are movably arranged on the bottom side of the horizontal frame plate, and pressure rollers are rotatably installed at the bottom ends of the movable arms. A pull-back spring with tension is provided on the inner end of the movable arm, and the end of the pull-back spring is connected and fixed to the bottom end of the horizontal frame plate. The pull-back spring applies a constant downward pulling force to the movable arm, so that the pressure rollers are in close contact with the surface of the blank plate, preventing the blank plate from jumping or shifting during the conveying process.
[0014] The present invention has at least the following beneficial effects: 1. By adopting a double milling cutter head design for the cutting parts, the groove is first opened and then repaired. Combined with piezoelectric ceramic actuators for dynamic vibration suppression, the vibration during the milling process is effectively reduced, the generation of groove wall vibration marks is avoided, and the groove dimensions are accurate, the depth is consistent and the surface is smooth, thus improving the pass rate of finished pencils.
[0015] 2. Through the coordinated action of the air blowing section and the dust collection module, the air force generated by the blower blows away the wood dust generated during the grooving process from the surface of the grooving plate and the processing area. The dust is guided to the dust collection module through the side grooves of the inner partition and the conveyor frame plate, and then pulled down by the cleaning wheel to the collection box for centralized storage. This avoids the dust residue in the groove of the grooving plate and the accumulation during transportation, ensuring the smooth progress of the subsequent core filling process.
[0016] 3. The return spring and pressure roller of the lower pressing section apply constant downward pressure to the blank plate to prevent the blank plate from shifting or jumping during the conveying process; the vibrator and pressure cover design of the feeding section promotes smooth feeding of the blank plate through vibration and counterweight pressure, avoids jamming, and improves the stability of equipment operation and production efficiency.

The bottom ends of the two threaded shafts 337 pass through the processing chamber 31 and are connected and fixed to the horizontal plate 335. Two suspension plates 333 are provided at the bottom of the horizontal plate 335, and milling cutter disc assemblies 331 are rotatably mounted on the front of each suspension plate 333. The shaft end of one of the milling cutter disc assemblies 331 passes through the suspension plate 333 and is connected to the shaft end of the drive motor B332. The drive motor B332 is fixed to the surface of the suspension plate 333 by a support plate. The shaft ends of the two milling cutter disc assemblies 331 are connected by a pulley assembly B336.

[0029] The pressing part 5 includes a horizontal frame plate 51 fixed on the left side of the processing chamber 31 and the material chamber 21. Several movable arms 52 are movably arranged on the bottom side of the horizontal frame plate 51, and pressure rollers 53 are rotatably installed on the bottom end of the movable arms 52. A pull spring 54 with tension is provided on the inner end of the movable arm 52, and the end of the pull spring 54 is connected and fixed to the bottom end of the horizontal frame plate 51.
[0030] Support 11 serves as the basic support for the equipment. Conveying module 12 is responsible for the stable conveying of the blank plate. Dust collection module 14 and storage box 13 form a dust collection system. The through-slot design allows dust to fall naturally and be centrally processed, reducing environmental pollution and equipment maintenance frequency. Conveying frame plate 121 limits and constrains the blank plate through side grooves and vertical plates to prevent deviation. Conveying belt group 122 is precisely controlled by servo motor to ensure that the blank plate enters the grooving section 3 at a uniform speed, providing a foundation for high-precision grooving. The semi-enclosed structure of processing chamber 31 reduces dust overflow and noise. The inner partition 34 and lower groove form a dust guiding channel, allowing dust to fall centrally to dust collection module 14. The cutting part 33 works in a closed environment, improving grooving accuracy and safety.
[0031] The side grooves facilitate the smooth entry of dust from the conveying area into the dust collection system; the collection box 13 is slidably installed via rails, making it easy to disassemble and clean, thus improving the convenience of equipment maintenance; the sweeping wheels 141 pull the dust down to the collection box 13 through relative rotation, and the gear 143 and pulley group A142 ensure that the two sweeping wheels 141 operate synchronously, the drive motor A144 provides power, and the cover plate 145 protects the transmission components from dust contamination, extending the equipment life; the rubber curtain plate 32 seals the blank plate when it enters and exits the processing chamber 31, reducing dust escape; the wiping rubber in the double-layer design is specially designed to clean residual dust in the groove of the slot plate, further ensuring the cleanliness of the slot plate surface.
[0032] By setting up two milling cutter heads 331, and synchronously driving them via a drive motor B332 and pulley group B336, a continuous machining unit is formed. In actual operation, the two milling cutter heads can be preset with different outer diameters, cutting edges, or speeds, so that they respectively undertake the functions of rough grooving and fine grooving. The grooving process is decomposed into two steps: the first milling cutter performs rough machining with a large cutting amount, and the second milling cutter performs fine finishing with a small allowance. This division of labor and cooperation mode greatly reduces the load on a single tool and the resulting vibration, enabling the production of high-quality pencil grooves with more precise dimensions, smoother groove walls, and no vibration marks, thus improving product yield. Piezoelectric electrodes are installed on the side wall of the drive motor B332. The piezoelectric ceramic actuator 334 is a smart material capable of high-speed, micro-precision expansion and contraction according to electrical signal commands. Through the matching installation of specified sensors (the sensor model can be selected and installed according to usage requirements), it monitors the vibration signal during the milling process and feeds it back to the control system. The control system then sends a reverse compensation signal to the piezoelectric ceramic actuator 334, which generates a reaction force with the opposite phase and equal amplitude to the vibration. This actively cancels the vibration of the drive motor and the milling cutter, greatly suppressing the transmission of vibration to the milling cutter from the vibration source, thereby directly eliminating the generation of vibration marks. It is a key technology guarantee for achieving ultra-high surface finish.
[0033] The nut fixing provides flexibility for height adjustment, the buffer spring 338 absorbs the impact force during the grooving process and protects the equipment structure; the suction fan through hole serves as a backup interface to enhance dust suction capacity when needed, and the rubber plug prevents dust from overflowing; the blower 42 generates high-pressure airflow, which forms a uniform airflow coverage through the air pipe 43 and the cross arm air pipe 44, quickly blowing the dust in the grooving area towards the dust collection system and preventing dust from adhering to the surface of the grooving plate.
[0034] The pressure cap 24 is suspended above the stack of blanks in the hopper 21 via a radial shaft 23. First, by adding a counterweight ring at the top of the radial shaft 23, a constant and adjustable downward pressure is provided to the pressure cap 24, promoting contact between the bottom blank and the conveyor belt. Second, the vibrator 25 installed on the surface of the pressure cap 24 generates high-frequency, low-amplitude mechanical vibration. The constant downward pressure overcomes the static friction between the blanks, guiding them to fall in an orderly manner. The vibration force generated by the vibrator 25 can effectively break the adsorption and jamming between the blanks and between the blanks and the hopper wall. The dual action of continuous pushing and intermittent vibration ensures that the blanks can be continuously, singly, and stably output from the discharge opening, fundamentally eliminating the problem of material jamming and ensuring seamless production.
[0035] The return spring 54 continuously applies a downward pull force to the movable arm 52. This force is transmitted to the surface of the pencil groove plate through the pressure roller 53 at the end of the movable arm 52. The pressure roller 53 provides a continuous and stable downward pressure, acting like a floating pressure plate to firmly press the blank plate onto the conveyor belt assembly 122, effectively suppressing the aforementioned jumping and displacement, and providing a crucial stable foundation for high-precision milling of the slotted section 3. The movable arm 52 and the cross plate 51 are movably connected, usually by a hinge or pivot, which allows the pressure roller 53 to act as a floating end, with a certain amount of vertical movement. When there are slight differences in the thickness of the blank plate or surface defects, this allows for flexibility in movement. In case of slight unevenness, the movable arm 52 can rotate around the axis to compress or release the pull-back spring 54, thereby automatically adjusting the height of the pressure roller 53. The adaptive design allows the equipment to gently handle different batches of blanks, avoiding damage to the blanks caused by excessive compression and preventing slippage due to insufficient pressure. This greatly improves the versatility and production yield of the equipment. The lower pressing part 5 is set at key positions on the left side of the feeding part 2 and the grooving part 3. It performs initial stabilization immediately after feeding and final pressing before entering the grooving. This multi-point arrangement forms continuous and stable control over the entire blank conveying process, ensuring the continuity and reliability of the entire process from feeding to processing completion.
[0036] Working principle: According to Figure 1 , Figure 3 and Figure 4 As shown, blanks are stacked inside the hopper 21. Under the action of gravity, the bottom blank contacts the surface of the conveyor belt end of the conveyor belt assembly 122. The drive wheel is rotated by the servo motor, which drives the conveyor belt end to move, pushing the blank at the bottom. During the movement, the blank is constrained and positioned by the vertical plates on both sides of the conveyor frame 121. The return force of the pull spring 54 pulls down the movable arm 52. The rotation of the movable arm 52 controls the pressure roller 53 to press down on the blank. When the blank moves into the processing chamber 31, in order to ensure the cutting stability of the blank, external clamping accessories can be added to limit the blank to a certain extent. This technology is a mature existing technology, so it will not be described in detail. Secondly, according to Figure 5 and Figure 6As shown, when the blank plate contacts the milling cutter assembly 331 during sequential pushing, it is started by the drive motor B332. The shaft end of the drive motor B332 drives the milling cutter assembly 331 to rotate. The milling cutter assembly 331 can move and groove the moving slot plate during high-speed rotation. Through specific design, such as the guide grooves adapted to the slot plate are opened on the inner wall side of both ends of the vertical plate of the conveyor frame plate 121. The guide grooves can limit and constrain the slot plate, so that grooving can be performed without the addition of external limiting parts. The pulley assembly B336 has the same structure as the pulley assembly A142, both of which are composed of a belt and two pulleys. When one of the drive motors B332 rotates, the other drive motor B332 can be controlled to rotate under the transmission of the pulley and the belt. The two drive motors B332 groove the blank plate in sequence. Grooving first and then repairing the groove can effectively reduce the probability of vibration marks and ensure the flatness of the groove. Secondly, according to Figure 8 As shown, the blower 42 is started synchronously under the control system. The air force generated by the blower 42 is split through the air pipe 43 and then sprayed out from the horizontal arm air pipe 44 in an arranged manner to form an impact convection. The debris is guided by the air force through the inner partition 34 and the side groove of the conveyor plate 121 to the lower groove of the processing chamber 31. One side of the inner wall of the lower groove is inclined to facilitate the debris falling into the through groove of the support 11. Figure 4 As shown, the drive motor A144 starts the circuit, and the shaft of the drive motor A144 drives one of the gears 143 to rotate. The two gears 143 mesh with each other. When one gear 143 rotates, the other gear 143 rotates in the opposite direction, and drives the sweeping wheel 141 to rotate through the pulley group A142. The two sweeping wheels 141 rotate relative to each other, which can pull down and guide the debris, so that the debris is stably moved into the collection box 13 for storage. An observation window is provided on the side of the collection box 13 for easy observation and regular cleaning by the staff. The top of the collection box 13 is provided with a rubber edge that contacts the bottom of the support 11. When the debris in the groove of the trough is cleaned, the trough passes through the two rubber curtains 32 when conveyed by the conveyor belt group 122. Figure 7 As shown, the rubber curtain 32 can clean the surface of the groove plate. The wiping rubber on the left side of the rubber curtain 32 is adapted to the groove position of the groove plate. The wiping rubber of the rubber curtain 32 can clean the residual powder in the groove of the groove plate, further ensuring the cleanliness of the groove plate surface. Finally, according to Figure 2As shown, when the material of the trough plate is rough and the falling resistance is large, causing jamming, the beam cover 22 can be fastened to the top of the hopper 21. The spring end of the clamping shaft 26 cooperates with the insert shaft, and the two ends of the spring end are fixed to the disc end of the insert shaft and the side plate end of the beam cover 22, respectively. When the insert shaft of the clamping shaft 26 is inserted into the corresponding groove on the surface of the hopper 21, the fixing is completed. A disc end is provided on the surface of the radial shaft 23, and a counterweight ring is stacked on the disc end. The counterweight increases the downward pressure of the pressure cover 24 on the trough plate blank. The resistance brought by the counterweight does not exceed the pushing force of the conveyor belt of the conveyor belt group 122 on the trough plate. In addition, it can also be started by the vibrator 25. The vibration force generated by the vibrator 25 can drive the pressure cover 24 to generate intermittent impact force on the trough plate blank, ensuring the stability of the trough plate blank moving downward and feeding.
