[0049] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0050] Please see also Figures 1 to 11 This utility model of an electric reed cutter includes a frame 1, a linear guide rail 2, an electric drive unit 3, a pusher head 4, a planer blade 5, and a positioning part 6. Wherein:

[0051] The frame 1 primarily serves a supporting function. In this specific embodiment, the frame 1 includes a housing 11 and a panel 12 disposed on the housing, the panel 12 being detachably attached to the upper surface of the housing 11. A linear guide rail 2, an electric drive device 3, a pusher head 4, and a planer blade 5 are disposed on the panel.

[0052] In this specific embodiment, a control module is provided inside the housing 11, and ventilation holes 111 are provided on the side of the housing 11. A cooling fan is provided on the inner side of the housing at the ventilation holes. The ventilation holes and the cooling fan can effectively dissipate heat from the inside of the machine.

[0053] Linear guide rail 2 is mounted on the frame. The linear guide rail is primarily used to ensure machining accuracy. In this specific embodiment, the linear guide rail includes two parallel lines, which improve the accuracy and stability of linear motion. The linear guide rail 2 is located on the lower end surface of the panel. The linear guide rail guides the movement of the front and rear sliders, ensuring the push head moves smoothly along a preset trajectory, thus improving operational accuracy and stability.

[0054] An electric drive unit 3 is mounted on the frame. In this specific embodiment, the electric drive unit 3 includes a drive motor 31 fixed to the panel, a lead screw 32 connected to the drive motor and rotating under the drive of the drive motor, and a sliding member 33 sleeved on the lead screw. The two ends of the sliding member are respectively connected to the linear guide rail and can move along the linear guide rail.

[0055] In this specific embodiment, to reduce the dimensions in the front-to-back direction, the drive motor is positioned below the lead screw, and drives the lead screw to rotate via belt 34. The drive motor is positioned with a 180-degree rotation, and transmits power to the push head 4 through a belt drive system. This design can better optimize the utilization of the internal space of the equipment, while ensuring the precise and reliable movement of the push head 4 through the smoothness of belt drive. This design reduces the space requirements of the equipment structure while maintaining smooth power transmission.

[0056] The drive motor drives the lead screw via a belt, which in turn drives the slider to move the pusher head. This effectively enhances the smoothness of power transmission and the precision of control, ensuring the equipment remains efficient and accurate during processing. The lead screw-driven linear slider system is the core drive component of the entire device, ensuring the accuracy of the pusher head's movement and the overall stability of the equipment.

[0057] The pusher 4 is connected to the electric drive device and moves back and forth along the linear guide rail under the drive of the electric drive device. In this specific embodiment, the pusher is fixedly connected to the slider.

[0058] The planer 5 is fixed to the frame and located in front of the pusher head. The planer 5 is used to process reeds. Since the planer is fixed, while the pusher head pushes the reed slices or reeds to move, the movement of the pusher head can be controlled by an electric drive device to accurately push the reed slices or reeds into the cutting edge of the planer, thereby improving the processing accuracy of the reed slices or reeds.

[0059] The positioning part 6 is located on the frame. The reed or bamboo reed is positioned on the positioning part and pushed into the planer blade by the pusher head. The positioning part is mainly used to position the reed or bamboo reed, so as to facilitate the pusher head to push the reed or bamboo reed into the planer blade.

[0060] This invention features a linear guide rail, an electric drive unit, a pusher head, a planer blade, and a positioning part mounted on a frame. The linear guide rail and electric drive unit are mounted on the frame, and the planer blade is fixed to the frame and located in front of the pusher head. The electric drive unit drives the pusher head to move back and forth along the linear guide rail. The positioning part is located on the frame, and reed pieces or reeds are positioned on the positioning part and pushed into the planer blade by the pusher head. Because the electric drive unit works in conjunction with the linear guide rail to drive the pusher head, and the planer blade is fixed in place, while the pusher head moves the reed pieces or reeds, the movement of the pusher head can be controlled by the electric drive unit, precisely pushing the reed pieces or reeds into the cutting edge of the planer blade. This improves the processing accuracy of the reed pieces or reeds and ensures the consistency of the reed production. Furthermore, due to the use of an electric drive unit, the structure is simple; simply fixing the reed pieces or reeds to the pusher head and starting the electric drive unit is sufficient for processing, making operation very simple and convenient.

[0061] In this specific embodiment, the upper surface of the panel 12 is provided with a downwardly recessed finishing groove 121. The planer 5 includes a precision planer circular cutter 51 disposed above the finishing groove. A precision planer material passage gap 59 is formed between the lower end face of the precision planer circular cutter 51 and the upper end face of the finishing groove. The precision planer material passage gap is used for the passage of processed reeds or bamboo shoots.

[0062] The electric reed cutter also includes a fine-tuning device 7 for adjusting the shape of the material passage gap. The fine-tuning device 7 is located below the fine-tuning circular cutter and within the finishing groove. The fine-tuning device is used to adjust the fine-tuning material passage gap formed between the lower end of the fine-tuning circular cutter and the upper end face of the finishing groove, thereby adjusting the processed shape and thickness of the reed slices or bamboo shoots.

[0063] In this specific embodiment, the fine-tuning device 7 includes a fine-tuning base 71, a fine-tuning support block 72, a fine-tuning spring 73, and a fine-tuning top rod (not shown in the figure). Wherein:

[0064] The fine-tuning base 71 is fixedly connected to the panel. The fine-tuning base is mainly used for fixation, and it can be fixed to the panel with screws.

[0065] The fine-tuning support block 72 is supported on the upper surface of the fine-tuning base. In this specific embodiment, the fine-tuning support block is located at the very center of the fine-tuning base.

[0066] The fine-tuning spring 73 is supported on the fine-tuning support block, with its left and right ends suspended and symmetrically arranged relative to the fine-tuning support block. The fine-tuning spring can deform under the action of the fine-tuning top rod, thereby adjusting the distance between the upper surface of the fine-tuning spring and the lower end of the fine-tuning circular cutter, that is, adjusting the fine-tuning material passage gap. This allows the reed or bamboo reed to change its shape and thickness as it passes through the fine-tuning circular cutter.

[0067] The fine-adjusting push rod is threadedly connected to the fine-adjusting seat. Two fine-adjusting push rods are included, with their upper ends respectively abutting the left and right ends of the fine-adjusting spring. The fine-adjusting push rods are symmetrically arranged, ensuring that the processed reed slices or reeds have a symmetrical shape. By adjusting the fine-adjusting push rods, the fine-adjusting spring is pressed against the fine-adjusting spring, causing deformation and changing the distance between the spring and the fine-planing cutter, thus altering the cutting shape and thickness of the reed slices or reeds. In this specific embodiment, the housing and the fine-adjusting seat are provided with through, inclined adjustment holes 74. The fine-adjusting push rods are threadedly connected to the adjustment holes on the fine-adjusting seat, allowing the fine-adjusting push rods to be rotated through the adjustment holes outside the housing to adjust the fine-adjusting spring, thereby adjusting the shape and thickness of the reed slices or reeds.

[0068] In this specific embodiment, the positioning part 6 includes a positioning groove 61 recessed downwards on the upper surface of the panel; the positioning groove 61 is parallel to the linear guide rail; a guide groove 62 parallel to the linear guide rail and penetrating the upper and lower surfaces of the panel is formed in the positioning groove 61; the lower end of the push head 4 is inserted into the guide groove and can move along the guide groove; a reed or bamboo reed is placed on the upper surface of the positioning groove and located at the front end of the push head. The fine planing guide groove not only serves a guiding function but also provides heat dissipation. In addition, the fine planing guide groove also serves a limiting function, preventing collision and damage to the planing blade even if the limit switch malfunctions.

[0069] The pusher 4 includes a pusher body 41 and a pusher positioning platform 42 located at the rear end of the lower surface of the pusher body and protruding downwards. The pusher positioning platform is used for fixed connection with the sliding component. The pusher is mainly used to push the reed forward, so that the reed slices or bamboo reeds move smoothly and ensure smooth processing. In this specific embodiment, the positioning groove is arc-shaped, the lower end face of the pusher body is also arc-shaped, and the left and right sides of the lower end face of the pusher body are located on the positioning groove.

[0070] The hollow structure of the guide groove 62 is designed specifically for the linear motion of the pusher head. This structure ensures that even if the limit switch fails, the pre-planing pusher head can still protect the planer blade from damage when the pusher head is moving in a linear motion, thereby improving the safety of the equipment and avoiding damage caused by operational errors or mechanical failures.

[0071] In this specific embodiment, the electric reed cutter further includes a fine planer blade holder 8 for fixing the fine planer blade. The fine planer blade holder 8 includes a fine planer fixing base 81, a fine planer adjusting base 82, an adjusting knob 83, a locking screw (not shown in the figure), and a fine adjustment screw (not shown in the figure). Wherein:

[0072] The precision planer mounting base 81 is fixed above the precision machining groove of the panel; the precision planer mounting base 81 is provided with a mounting cavity 811 that penetrates the lower end face of the precision planer mounting base and a discharge cavity 812 that penetrates the lower end of the front and rear end faces of the precision planer mounting base in the front-back direction; the upper end face of the precision planer mounting base is provided with a knob hole 813 that communicates with the mounting cavity.

[0073] The front side of the precision planer fixing seat is provided with a locking groove 815 that penetrates into the cavity of the fixing seat in the vertical direction; the left and right sides of the precision planer fixing seat are provided with fine adjustment holes 816 that penetrate into the cavity of the fixing seat.

[0074] In this specific embodiment, the precision planer mounting base includes a base body 819, a cover body 818 covering the base body, and a rear cover plate 817 covering the rear end of the base body.

[0075] The precision planing adjustment seat 82 is disposed within the cavity of the fixed seat and can move up and down relative to the precision planing fixed seat. The lower end of the precision planing adjustment seat has a circular blade cavity 821 penetrating the lower ends of its front and rear end faces. The upper end face of the precision planing adjustment seat has a fixing hole 822. A limiting step 823 is provided inside the circular blade cavity of the precision planing adjustment seat. The circular blade cavity communicates with the discharge cavity. The front side of the precision planing adjustment seat has a locking hole 824 directly opposite the locking groove.

[0076] The precision planing cutter 51 is secured within the cutter cavity, and its rear end face abuts against the limiting step 823. In this specific embodiment, the cross-section of the inner surface of the cutter cavity is not perfectly circular. The precision planing cutter is securely connected to the cutter cavity, and then a screw passes through the hole 825 on the upper end face of the precision planing adjustment seat, pressing downwards against the precision planing cutter to prevent rotation, thereby fixing the precision planing cutter. The limiting step can counteract the axial pressure on the precision planing cutter.

[0077] The discharge chamber 812 is used to discharge waste generated during processing. In this specific embodiment, the front end of the precision planing adjustment seat 82 abuts against the rear end face of the fixed seat cavity, thereby counteracting the forward pressure of the precision planing cutter during cutting, thus protecting the cutter and extending its service life.

[0078] The adjusting knob 83 is connected to the knob hole and the fixing hole, and rotating the adjusting knob can cause the precision planing adjusting seat to move up and down relative to the precision planing fixing seat. The adjusting knob 83 is inserted into the knob hole and can rotate relative to the knob hole. The adjusting knob is threadedly connected to the fixing hole. Rotating the adjusting knob 83 causes the precision planing adjusting seat to move up and down relative to the precision planing fixing seat. By adjusting the adjusting knob, the up and down position of the precision planing adjusting seat can be adjusted, thereby achieving the adjustment of the up and down position of the precision planing circular cutter.

[0079] A locking screw (not shown in the figure) is inserted into the locking groove and threaded into the locking hole. The locking screw secures the precision planer adjusting seat to the precision planer fixed seat in the front-to-back direction, allowing the precision planer adjusting seat to better withstand the forces exerted on the precision planer cutter in the front-to-back direction. The locking groove allows the locking screw to move up and down within it, thus better adapting to the vertical position of the precision planer adjusting seat.

[0080] Two fine-tuning screws (not shown in the figure) are included. These two screws are threaded into the fine-tuning holes on the left and right sides respectively, and press against the precision planing adjustment seat from both sides. The left and right positions of the precision planing adjustment seat can be finely adjusted using these screws, thereby adjusting the axis of the precision planing cutter. This ensures that the center of the pusher and the axis of the precision planing cutter are on the same plane, guaranteeing symmetry in the processing of reeds or bamboo.

[0081] In this specific embodiment, a discharge limiting shim 122 is also provided on the panel 12. The discharge limiting shim is located above the finishing groove and in front of the finishing cutter holder. The processed reed chips or bamboo shoots are discharged between the discharge limiting shim and the finishing groove, while the cut-off waste is discharged from above the discharge limiting shim. The discharge limiting shim is used to manually adjust the discharge pressure. By adjusting the height of the shim, the pressure on the discharge during processing can be effectively controlled, ensuring that the material can be discharged smoothly without affecting the processing quality.

[0082] To further facilitate material discharge, a discharge hole 814 is provided at the lower front end of the precision planer mounting base 81. The discharge hole is designed to remove linear or filamentous waste that may occasionally be generated during cutting. Although such waste is rare during processing, the discharge hole can prevent its accumulation, ensuring that the inner cavity of the equipment remains clean and does not affect processing efficiency.

[0083] In this specific embodiment, the electric reed trimmer also includes a thickness gauge 84, which is connected to the fine trimming adjustment seat and detects the movement distance of the fine trimming adjustment seat, thereby accurately determining the adjustment of the fine trimming adjustment seat. In this specific embodiment, the fine trimming fixed seat is provided with a vertical movement groove 80. The thickness gauge is inserted into the movement groove and fixedly connected to the fine trimming adjustment seat via a crossbar 841. Thus, when the fine trimming adjustment seat moves up and down, the crossbar moves up and down in the movement groove accordingly, allowing the movement distance of the fine trimming adjustment seat to be measured by the thickness gauge.

[0084] In this specific embodiment, in order to facilitate the simultaneous implementation of roughing and finishing, two processing stations, pre-planing and finishing planing, are set on the panel. The structure of the finishing planing station is basically the same as that of the pre-planing station, so that pre-planing and finishing can be performed on one machine at the same time.

[0085] The planer 5 also includes a pre-planing blade 52 fixed to the panel and a pre-planing circular cutter 53 located in front of the pre-planing blade; the pusher 4 includes a finish planing pusher 43 and a pre-planing pusher 44. By arranging the pre-planing blade and the pre-planing circular cutter in front and behind, two planing operations can be performed at once, improving processing efficiency.

[0086] The positioning groove 61 includes a precision planing positioning groove 611 and a pre-planing positioning groove 612 parallel to the precision planing positioning groove. The guide groove 62 includes a precision planing guide groove 621 and a pre-planing guide groove 622 parallel to the precision planing guide groove. The pre-planing blade 52 is disposed at the upper end of the pre-planing guide groove 621.

[0087] The lower end of the planing pusher 43 is inserted into the planing guide groove 621 and can move along the planing guide groove. The lower end of the planing pusher 44 is inserted into the planing guide groove 622 and can move along the planing guide groove.

[0088] During fine planing, reed strips or bamboo shoots are placed on the upper surface of the fine planing positioning groove and positioned at the front end of the fine planing pusher. During pre-planing, reed strips or bamboo shoots are placed on the upper surface of the pre-planing positioning groove and positioned at the front end of the pre-planing pusher.

[0089] The upper surface of the panel 12 is also provided with a downwardly recessed pre-processing groove 123, and a pre-planing material passage gap is formed between the lower end face of the pre-planing circular cutter 53 and the upper end face of the pre-processing groove.

[0090] Both the pre-planing circular cutter 53 and the fine planing circular cutter 51 include a circular shaft hole 59 located at the axial center and a circular cutter body 58 axially surrounding the circular shaft hole.

[0091] The fixing and adjustment structure of the pre-planing circular cutter is the same as that of the finishing circular cutter. The pre-planing circular cutter 53 is also fixed and adjusted by the pre-planing cutter holder, and the structure of the pre-planing cutter holder is the same as that of the finishing cutter holder.

[0092] In this specific embodiment, to further position the reeds or reeds, the electric reed cutter also includes a pre-planing positioning roller 91 located on the upper surface of the panel and directly above the pre-planing positioning groove, and a fine planing positioning roller 92 located directly above the fine planing positioning groove. The pre-planing positioning roller includes a front pre-planing positioning roller 911 located between the pre-planing circular blade and the pre-planing blade, and a rear pre-planing positioning roller 912 located behind the pre-planing blade.

[0093] When the planing pusher moves the reed or bamboo strip forward, it pushes the strip into the planing positioning groove and the planing positioning roller. The planing positioning roller positions the reed or bamboo strip from above, preventing it from moving vertically. When the pre-planing pusher moves the reed or bamboo strip forward, it pushes the strip into the pre-planing positioning groove and the pre-planing positioning roller. The pre-planing positioning roller positions the reed or bamboo strip from above, preventing it from moving vertically.

[0094] In this specific embodiment, the slider adopts a reverse installation design, meaning it is positioned below the linear guide rail, thus enabling the connection between the dual guide rails and the central lead screw. This design not only securely positions the rails at the bottom of the panel but also effectively controls the movement of the pusher head, precisely pushing the reed or bamboo blade into the cutting edge. Simultaneously, the slider structure conceals the location of the stroke trigger, enhancing aesthetics. Furthermore, the pusher head and slider employ a detachable connection structure, thereby improving the flexibility of the equipment and meeting diverse usage requirements.

[0095] In this specific embodiment, the electric reed cutter further includes a pusher groove 124 located at the front end of the fine planing guide groove and the pre-planing guide groove and formed by the downward recess of the upper surface of the panel. The fine planing pusher 43 and the pre-planing pusher 44 are also provided with a step top 45 located at the front end of the lower surface of the pusher body and protruding downward. The step top has the same shape as the pusher groove, and when the pusher moves forward to the foremost position, the step top is inserted into the pusher groove.

[0096] The pusher groove is a special groove designed for the pusher head, optimized for ultra-thin and soft materials to prevent these materials from entering the machine gaps during processing. This design ensures smooth and precise processing, especially when handling highly flexible and thin materials, effectively avoiding processing errors or equipment malfunctions caused by material getting stuck in gaps.

[0097] The main purpose of the stepped top design is to prevent thin material from entering below the pusher head, thus avoiding material jamming during processing. This design allows for better control of thin material during processing, ensuring processing quality and precision.

[0098] In this specific embodiment, in order to limit the sequential movement position of the pusher head, the electric reed cutter of this utility model also includes limit sensors 93 disposed on the frame and located in front of and behind the pusher head respectively. When the pusher head moves to the set range of the limit sensor, a stop signal is sent to control the electric drive device to stop moving.

[0099] To prevent the pusher head from colliding with the planer blade due to limit sensor malfunction, a limit impact block 94 is installed on the frame in front of the pusher head. When the limit sensor malfunctions, the sliding component will first collide with the limit impact block, thereby preventing the pusher head from colliding with the planer blade.

[0100] In this specific embodiment, in order to effectively collect the processing waste falling from the wire groove, the present invention also provides a waste collection plate 95 below the guide groove.

[0101] This utility model has the following features:

[0102] 1. High Precision. Traditional manual reed planing involves the planer moving while the reed or bamboo remains stationary. This causes the planer to slightly shift or lift the material when applying pressure, resulting in inconsistent thickness at both ends. This new invention employs a reverse approach in its motion principle: the material moves while the planer remains stationary. Furthermore, it guides and restricts the material in all directions, significantly improving overall precision. This electric reed planer provides oboe players with a simple and highly precise tool for planing reeds. It not only improves reed production efficiency but also allows for high-precision planing and adjustment of reeds or bamboo, achieving a maximum precision of 0.01mm. This greatly enhances the quality and consistency of oboe reed or bamboo production.

[0103] 2. Low difficulty of use. Traditional reed-shaving machines exert very high pressure on the material, often causing it to break. This is because traditional machines require shaving the material thinner in multiple passes, and the number of passes depends on the pressure applied by the user and the thickness of the reed itself. In contrast, this new invention achieves the target data in just two steps, and all manual effort is replaced by machine operation, thus solving the variables and difficulties in use.

[0104] 3. Low time and economic costs. It reduces user time costs, saving significant time by reducing the number of reciprocating motions to two cutting operations. Previously, machines took approximately 2 minutes to cut a single reed or bamboo shoot, while the electric machine can complete the cut in just 20 seconds. Its simple structure also results in low cost.

[0105] This invention can be used for processing reeds or bamboo reeds for double-reed musical instruments such as oboes, horns, bassoons, and suonas.
