The lower end of the push head 4 is inserted into the guide groove and can move along the guide groove. The reed or bamboo cane is placed on the upper surface of the positioning groove and in front of the push head. The fine planing guide groove not only has a guiding effect but also has a heat dissipation effect. In addition, the fine planing guide groove also has a limiting effect. Even if the travel switch malfunctions, the push head can still protect the planer from damage, improving the safety of the equipment and avoiding damage caused by operation errors or mechanical failures.

[0069] The push head 4 comprises a push head body 41 and a push head positioning platform 42 which is convex downward on the lower surface of the rear end of the push head body.

In the embodiment, the positioning groove is arc-shaped, the lower end surface of the push head body is also arc-shaped, and the left and right sides of the lower end surface of the push head body are located on the positioning groove.

[0070] The guide groove 62 adopts a hollow structure which is specially designed for the linear motion of the push head. This structure ensures that the push head can protect the planer from damage even if the travel switch malfunctions when the push head is linearly moving, improves the safety of the equipment, and avoids damage caused by operation errors or mechanical failures.

[0071] In the embodiment, the electric reed planer further comprises a fine planing seat 8 which is used for fixing the fine planer. The fine planing seat 8 comprises a fine planing fixing seat 81, a fine planing adjusting seat 82, an adjusting knob 83, a locking screw (not shown in the figure) and a fine adjustment screw (not shown in the figure). Among them:

[0072] The fine planing fixing seat 81 is fixed above the fine machining groove of the panel. The fine planing fixing seat 81 is provided with a fixing seat cavity 811 which penetrates the lower end surface of the fine planing fixing seat and a discharge cavity 812 which penetrates the lower end of the front and rear end surfaces of the fine planing fixing seat in the front and rear directions. The upper end surface of the fine planing fixing seat is provided with a knob hole 813 which communicates with the fixing seat cavity.

[0073] The front side of the fine planing fixing seat is provided with a locking groove 815 which penetrates the fixing seat cavity in the up and down direction. The left and right sides of the fine planing fixing seat are provided with fine adjustment holes 816 which penetrate the fixing seat cavity.

[0074] In the embodiment, the fine planing fixing seat comprises a seat body 819, a cover body 818 which covers the seat body and a rear cover plate 817 which covers the rear end of the seat body.

[0075] The fine planing adjusting seat 82 is arranged in the fixed seat cavity and can move up and down relative to the fine planing fixed seat. The lower end of the fine planing adjusting seat is provided with a circular knife cavity 821 penetrating the lower end of the front and rear end faces of the fine planing adjusting seat. The upper end face of the fine planing adjusting seat is provided with a fixed hole 822. The fine planing adjusting seat is provided with a limiting step 823 inside the circular knife cavity. The circular knife cavity is communicated with the material discharging cavity. The front side of the fine planing adjusting seat is provided with a locking hole 824 opposite to the locking groove.

[0076] The fine planing circular knife 51 is clamped in the circular knife cavity and the rear end face of the fine planing circular knife abuts against the limiting step 823. In the specific embodiment, the cross section of the inner surface of the circular knife cavity is not completely circular. The fine planing circular knife is clamped and connected with the circular knife cavity, and then a screw is passed through the hole 825 in the upper end face of the fine planing adjusting seat to press the fine planing circular knife downward, so as to prevent the fine planing circular knife from rotating, thereby achieving the fixation of the fine planing circular knife. The limiting step can offset the axial pressure received by the fine planing circular knife.

[0077] The material discharging cavity 812 is used for discharging the waste generated during processing. In the specific embodiment, the front end of the fine planing adjusting seat 82 abuts against the rear end face of the fixed seat cavity, so as to offset the forward pressure of the fine planing circular knife during cutting, thereby protecting the tool and prolonging the service life thereof.

[0078] The adjusting knob 83 is connected with the knob hole and the fixed hole, and rotating the adjusting knob can drive the fine planing adjusting seat to move up and down relative to the fine planing fixed seat. The adjusting knob 83 is inserted in the knob hole and can rotate relative to the knob hole. The adjusting knob is threadedly connected with the fixed hole. Rotating the adjusting knob 83 drives the fine planing adjusting seat to move up and down relative to the fine planing fixed seat. The up and down position of the fine planing adjusting seat is adjusted through the adjusting knob, so as to adjust the up and down position of the fine planing circular knife.

[0079] The locking screw (not shown in the figure) is inserted in the locking groove and is threadedly connected with the locking hole. Through the locking screw, the front and rear directions of the fine planing adjusting seat can be fixed with the fine planing fixed seat, so that the fine planing adjusting seat can better bear the force received by the fine planing circular knife in the front and rear directions. The locking groove is arranged so that the locking screw can move up and down in the locking groove, thereby better adapting to the up and down position of the fine planing adjusting seat.

[0080] The fine tuning screws (not shown in the figure) include two. The two fine tuning screws are respectively threadedly connected with the fine tuning holes on the left and right sides and respectively press the fine planing adjusting seat from the left and right sides. The left and right positions of the fine planing adjusting seat can be fine tuned through the fine tuning screws on the left and right sides, so as to adjust the axis of the fine planing circular knife, so that the center of the push head and the axis of the fine planing circular knife are on the same plane, so as to ensure the symmetry of the processing of reed or bamboo cane.

[0081] In the embodiment, the panel 12 is further provided with a discharge limiting gasket 122 above the finishing groove and in front of the finishing cutter holder. The finished reed or bamboo is discharged from the space between the discharge limiting gasket and the finishing groove, and the cut waste is discharged from above the discharge limiting gasket. The discharge limiting gasket is used to manually adjust the discharge pressure. By adjusting the height of the gasket, the discharge pressure during the processing can be effectively controlled to ensure that the material can be smoothly discharged without affecting the processing quality.

[0082] To further facilitate the discharge, a discharge hole 814 is further provided at the lower end in front of the finishing cutter holder 81. The discharge hole is designed to discharge the linear or filamentous waste occasionally generated during the cutting. Although the occurrence of such waste is a small probability during the processing, the discharge hole can prevent the accumulation of the waste and ensure that the inner cavity of the equipment remains clean, thereby not affecting the processing efficiency.

[0083] In the embodiment, the electric reed planer further comprises a thickness gauge 84 connected with the finishing cutter adjusting holder and detecting the moving distance of the finishing cutter adjusting holder, so that the adjustment of the finishing cutter adjusting holder can be accurately known. In the embodiment, the finishing cutter holder is provided with a moving groove 80 in the up-down direction, and the thickness gauge is inserted into the moving groove through a cross rod 841 and fixedly connected with the finishing cutter adjusting holder. When the finishing cutter adjusting holder moves up and down, the cross rod moves up and down in the moving groove, so that the moving distance of the finishing cutter adjusting holder can be measured by the thickness gauge.

[0084] In the embodiment, to facilitate the simultaneous implementation of rough processing and finishing processing, the panel is simultaneously provided with two processing stations of pre-planing and finishing, and the structure of the finishing processing station is basically the same as that of the pre-planing processing station, so that the pre-planing and finishing processing can be simultaneously performed on one equipment.

[0085] The planer cutter 5 further comprises a pre-planing cutter blade 52 fixed to the panel and a pre-planing round cutter 53 arranged in front of the pre-planing cutter blade, and the push head 4 comprises a finishing push head 43 and a pre-planing push head 44. The front and rear arrangement of the pre-planing cutter blade and the pre-planing round cutter can perform two planing at a time, thereby improving the processing efficiency.

[0086] The positioning groove 61 comprises a finishing positioning groove 611 and a pre-planing positioning groove 612 parallel to the finishing positioning groove, and the guide groove 62 comprises a finishing guide groove 621 and a pre-planing guide groove 622 parallel to the finishing guide groove.

[0087] The lower end of the finishing push head 43 is inserted into the finishing guide groove 621 and can move along the finishing guide groove. The lower end of the pre-planing push head 44 is inserted into the pre-planing guide groove 622 and can move along the pre-planing guide groove.

[0088] When planing, the reed slice or bamboo cane is placed on the upper surface of the planing positioning groove and at the front end of the planing pusher. When pre-planing, the reed slice or bamboo cane is placed on the upper surface of the pre-planing positioning groove and at the front end of the pre-planing pusher.

[0089] The upper surface of the panel 12 is further provided with a downwardly recessed pre-planing groove 123, and a pre-planing material gap is formed between the lower end surface of the pre-planing round knife 53 and the upper end surface of the pre-planing groove.

[0090] The pre-planing round knife 53 and the planing round knife 51 each include an axially central round shaft hole 59 and an axially surrounding round knife body 58.

[0091] The fixing and adjusting structure of the pre-planing round knife is the same as that of the planing round knife, and the pre-planing round knife 53 is also fixed and adjusted by the pre-planing knife seat, which has the same structure as the planing knife seat.

[0092] In the specific embodiment, to further position the reed slice or bamboo cane, the electric reed planer further includes a pre-planing positioning roller 91 located above the pre-planing positioning groove on the upper surface of the panel and a planing positioning roller 92 located above the planing positioning groove, the pre-planing positioning roller including a front pre-planing positioning roller 911 located between the pre-planing round knife and the pre-planing blade and a rear pre-planing positioning roller 912 located behind the pre-planing blade.

[0093] When the planing pusher pushes the reed slice or bamboo cane forward, the reed slice or bamboo cane is pushed into the planing positioning groove and the planing positioning roller, and the reed slice or bamboo cane is positioned from above by the planing positioning roller to prevent the reed slice or bamboo cane from moving in the up-down direction. When the pre-planing pusher pushes the reed slice or bamboo cane forward, the reed slice or bamboo cane is pushed into the pre-planing positioning groove and the pre-planing positioning roller, and the reed slice or bamboo cane is positioned from above by the pre-planing positioning roller to prevent the reed slice or bamboo cane from moving in the up-down direction.

[0094] In the specific embodiment, the slide is designed in a reverse mounting manner, that is, the slide is arranged below the linear guide rail, so that the connection of the double guide rails and the middle screw rod can be achieved. This design not only can stably place the rail on the bottom of the panel, but also can effectively control the movement of the pusher to accurately push the reed slice or bamboo cane into the blade. At the same time, the slide structure can hide the position of the stroke trigger part, enhancing the aesthetic appearance. In addition, the connection structure between the pusher and the slide is detachable, thereby improving the flexibility of the equipment and meeting different use requirements.

[0095] In this embodiment, the electric reed planer further includes a push head groove 124 located at the front end of the fine planing guide groove and the pre-planing guide groove, which is recessed downward from the upper surface of the panel. The fine planing push head 43 and the pre-planing push head 44 are also located at the front end of the push head body lower surface and protrude downward as a step head 45. The step head has the same shape as the push head groove, and when the push head moves forward to the front end, the step head is inserted into the push head groove.

[0096] The push head groove is a special groove designed for the push head, which is optimized for ultra-thin soft materials to prevent them from entering the mechanical gap during processing. This design ensures smoothness and accuracy of processing, especially when dealing with high flexibility and thin materials, effectively avoiding processing errors or equipment failures caused by material jamming in the gap.

[0097] The main purpose of the step head design is to prevent thin materials from entering the lower part of the push head, avoiding the situation of material jamming during processing. Through this design, thin materials can be better controlled during processing, ensuring processing quality and accuracy.

[0098] In this embodiment, in order to determine the position of the limit push head, the electric reed planer further includes limit sensors 93 located on the frame and positioned in front of and behind the push head respectively. When the push head moves to the set range of the limit sensor, the limit sensor sends a stop signal to control the electric drive device to stop moving.

[0099] To avoid the situation that the push head hits the planer due to the failure of the limit sensor, a limit impact block 94 is also provided in front of the push head on the frame. When the limit sensor fails, the sliding member will first hit the limit impact block, preventing the push head from hitting the planer.

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

[0101] The invention has the following characteristics:

[0102] 1. High precision. Because the traditional manual reed planer moves the planer and keeps the reed or bamboo still, it causes the planer to move slightly or lift the cutting object when applying pressure, resulting in inconsistent thickness of the head and tail. However, the invention adopts reverse thinking in the movement principle, keeping the material moving and the planer still, and limiting the material in all directions, which improves the front and rear precision. The electric reed planer provides a simple and highly precise reed tool for double reed players, which not only improves the efficiency of reed production, but also allows for high-precision planing and adjustment of reed or bamboo, with a maximum precision of 0.01mm, greatly improving the quality and consistency of double reed reed production.

[0103] 2、Low difficulty in use. The previous reed machine has a very large pressure on the material, so that the material is often pressed and damaged. Because the previous machine needs to thin the material many times, and the number of overcutting is not certain, it needs to see the pressure of the user to the planer and the thickness of the reed itself to determine, while the present invention only needs two steps to achieve the target data, and all through the action of the machine to replace the manual force, which solves the variable and difficulty in use.

[0104] 3、Low time cost and economic cost. The time cost of the user is reduced from multiple reciprocating motion to twice cutting, which saves a lot of time. The previous machine spends about 2 minutes on a reed or cane, while the electric machine can complete in 20 seconds on a reed. Because of simple structure and low cost.

[0105] The present invention can be used for processing reed or cane of double reed instruments such as oboe, English horn, bassoon and so on.

[0106] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
