Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument reed production, in particular to a multi-blade head reed planer capable of forming reeds at one time. Background Art

[0002] Woodwind instruments such as oboe, clarinet, saxophone, etc. usually need to use reeds. The reed is usually made of reed (the object to be processed and in the process of processing is referred to as reed in this article, and the product after the reed is processed into shape is referred to as reed). In order to obtain a reed that is more suitable for the individual, the performer will choose to make it by himself. For example, it can be made by hand shaving or by simple tools. However, the reed has high requirements for precision, and it is difficult to achieve the precision requirements by hand shaving or simple tools. There are often problems such as uneven thickness of the reed, low surface smoothness, irregular shape, etc., which affect the pronunciation effect of the instrument.

[0003] In the prior art, in order to facilitate the production of reeds and ensure the production accuracy, there are also reed planing machines that use planer-like equipment. However, the existing reed planing machines perform rough and fine planing on the same blade for multiple times, and the planing thickness is difficult to meet the requirements. The blade will easily become blunt after multiple planing of the reed, and the blade life is short. Moreover, continued planing will cause the planed surface of the reed to be rough and unusable. In addition, since the reed cannot be well fixed during the planing process, it is very easy to cause the reed to deviate and slide. In addition, the existing reed planing machines also have problems such as inconvenient operation, low planing efficiency, and insufficiently sophisticated equipment. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above problems and / or other problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, according to one aspect of the utility model, a multi-blade head reed planer is provided, the multi-blade head reed planer comprises a base, a slider assembly and a blade assembly arranged on the base. The base is provided with a slideway extending along a first direction, the first direction being the feeding direction of the reed material; the slider assembly comprises a slider body at least partially accommodated in the slideway and capable of sliding along the slideway, the slider body is provided with a positioning portion suitable for positioning the reed material; the blade assembly comprises a plurality of blades arranged in sequence in the first direction, the plurality of blades being configured to gradually plane the reed material when the slider assembly drives the reed material to pass through each blade head in sequence.

[0006] In the above scheme, when the slider body drives the reed to pass through multiple cutter heads in sequence, the multiple cutter heads gradually plan the reed in sequence, and the planing is completed after the reed passes through the cutter head assembly. The rough planing and fine planing processes are completed at one time, with high planing efficiency and simple operation. Compared with the prior art method of using one cutter head for rough planing and fine planing, the multi-cutter head scheme in this scheme can give different cutter heads different cutting functions, and will not cause a cutter head to be used for both rough planing and fine planing, which greatly improves the life of the blade.

[0007] According to an example of the utility model, each of the cutter heads is respectively arranged on the base in a manner of crossing the slideway, and each of the cutter heads respectively includes a cutting portion located above the reed material, wherein the curvature of the cutting portion of at least two of the cutter heads is different.

[0008] In this exemplary solution, the curvature of the cutting portion of at least two cutter heads, preferably each cutter head, is different, so that different depths of reed material can be planed as needed. Moreover, each cutter head is respectively arranged on the base in a cross-slide manner, and the cutting portion is suspended above the reed material on the slider body, so as to facilitate planing of various parts of the reed material.

[0009] According to an example of the utility model, the cutter head assembly further comprises an adjustment mechanism for adjusting the height between the tail cutter in the plurality of cutter heads and the slider body. The adjustment mechanism enables the size of the reed flakes finally shaved to be freely controlled according to the user's personal habits.

[0010] According to an example of the utility model, the adjustment mechanism includes a first adjustment member connected to the tail knife and a second adjustment member arranged in the base, and the first adjustment member and the second adjustment member cooperate with each other to adjust the lifting and lowering of the tail knife by moving the second adjustment member relative to the base.

[0011] According to an example of the utility model, the bottom of the first adjusting member is provided with a first mating surface inclined along a second direction transverse to the first direction and a mating groove inclined in the same direction as the first mating surface, and the top of the second adjusting member is provided with a second mating surface engaged with the first mating surface and a mating block capable of sliding in the mating groove to guide the second adjusting member. This structure converts the movement of the second adjusting member along the second direction into the movement of the first adjusting member along a third direction (vertical direction relative to the bottom of the entire reed planer) perpendicular to the first direction and the second direction through the mutual cooperation between the first mating surface and the second mating surface, the mating groove and the mating block, thereby realizing the lifting and lowering of the tail knife relative to the slider body.

[0012] According to an example of the utility model, a receiving groove is provided in the base, the first adjusting member and the second adjusting member are provided in the receiving groove, and the reed planer further comprises a cover plate provided at the bottom of the base to at least partially cover the receiving groove. In this solution, the height adjustment mechanism is basically located in the receiving groove of the base, so that the whole reed planer has a compact structure, a sophisticated design, a small volume, and is easy to store, carry and use.

[0013] According to an example of the utility model, the adjustment mechanism further includes two knobs connected to both sides of the cover plate along the Y direction, each of the knobs is threadedly connected to the cover plate and is respectively suitable for abutting the second adjustment member. This structure can adjust the height of the first adjustment member outside the base through the knob, which is easy to operate. And the adjustment mechanism is located at the bottom cover plate, making the structure of the entire reed planer more compact.

[0014] According to an example of the utility model, the first blade among the plurality of blades is a flat blade with zero curvature. This structure facilitates cutting both sides of the reed material flat and removing the excess parts on both sides of the reed material, so as to facilitate subsequent planing and shaping.

[0015] According to an example of the utility model, the cutter head assembly further includes a pressure block and a first elastic member disposed between the tail cutter among the plurality of cutter heads and the remaining plurality of cutter heads, and the first elastic member biases the pressure block to press the reed material onto the slider body. In this solution, the first elastic member presses the pressure block downward, and the pressure block presses on the reed material, and the reed material planed by the remaining plurality of cutter heads continues to be pressed onto the slider body, which is beneficial to improving the dimensional stability of the tail cutter when planing the reed material.

[0016] According to an example of the utility model, each of the cutter heads is respectively arranged on the top of the base in a manner of crossing the slideway, and the cutter head assembly further includes two end plates respectively connected to both sides of the base in the second direction, and each of the end plates abuts against the corresponding ends of the pressure block and the remaining multiple cutter heads to limit the pressure block and the remaining multiple cutter heads in the second direction. In this solution, the pressure block and the remaining multiple cutter heads are limited in the second direction by the two end plates, so as to achieve better fixation.

[0017] According to an example of the utility model, the positioning portion includes an arc-shaped groove extending along the first direction at the top of the slider body and adapted to the outer circumference curvature of the reed material.

[0018] The arc-shaped groove of this structure fits the reed material to position it through surface contact, which is beneficial to improving the positioning accuracy of the reed material and further improving its processing accuracy.

[0019] According to an example of the utility model, the positioning portion further includes a stopper adapted to abut against an end of the reed material away from the cutter head assembly.

[0020] This solution positions the reed material by means of a stopper at the end, pushes the reed material forward under the drive of the sliding body, and achieves better positioning of the reed material to prevent it from sliding.

[0021] According to an example of the utility model, a groove connected to the arc-shaped groove is also formed on the slider body, and a stopper is arranged in the groove. The slider assembly also includes a second elastic member arranged in the groove and located between the slider body and the stopper, wherein the stopper can be in an extended state and a retracted state relative to the groove, and in the extended state, under the bias of the second elastic member, the end of the stopper extends into the arc-shaped groove to be suitable for abutting against the reed material; in the retracted state, the stopper is pressed downward and retracted to a position where its end is suitable for abutting against the reed material and the end is located below the multiple blade heads in height.

[0022] In this exemplary scheme, the retractable stopper can not only reliably abut the reed material to complete its positioning during the entire planing process, but also enable the stopper to smoothly pass through multiple cutter heads (and pressing blocks) to ensure the planing of the entire reed material including the rear end part, realize one-time forming of the reed sheet, and ensure that the size of the entire reed sheet is uniform.

[0023] According to an example of the utility model, the cutter head assembly also includes two lining plates located between the two ends of other cutter heads among the multiple cutter heads except the tail cutter and the base, and the stopper is provided with two positioning blocks corresponding to the two lining plates, each of the lining plates is suitable for abutting against the corresponding positioning block to press the stopper down to the retracted state.

[0024] The lining plate in this exemplary solution can play the role of pressing down the stopper, so that the stopper moves from the extended state to the retracted state. Moreover, the thickness of the lining plate can be designed to adjust the distance between the cutter head and the base, and then adjust the distance between the cutter head and the reed material on the slider body, so as to ensure that the cutter head has a suitable planing depth for the reed material.

[0025] According to an example of the utility model, one end of the lining plate facing the stopper is provided with a first inclined surface inclined toward the bottom surface of the lining plate, and one end of the positioning block facing the lining plate is provided with a second inclined surface capable of cooperating with the first inclined surface. When the stopper passes through the lining plate, the stopper is pressed down to the retracted state by the lining plate through the cooperation of the first inclined surface and the second inclined surface.

[0026] According to an example of the utility model, the slider body is provided with limiting portions on both sides corresponding to the arc groove, and each lining plate extends from the top of the base to above the slide and engages with the corresponding limiting portion to limit the slider body within the slide.

[0027] Through this solution, the lining plate of the utility model further has the function of limiting the slider body in the slideway during the planing process. Furthermore, the same lining plate plays multiple roles in the entire structure, avoiding the use of multiple components, reducing the number of parts of the reed planer, making the entire design not only reliable in operation, but also exquisite in structure, easy to manufacture, and small in volume.

[0028] According to an example of the utility model, the slider assembly further includes a limiter fixed in the groove and located on one side of the stopper, the limiter is provided with a limiter groove, the stopper is provided with a protrusion protruding into the limiter groove and capable of sliding therein, and the top wall of the limiter groove is suitable for abutting against the protrusion to limit the stopper. This solution achieves the limitation of the upward stroke of the stopper with a simple structure, and prevents the stopper from falling out of the groove.

[0029] According to an example of the utility model, the multi-blade reed planer also includes a connecting rod mechanism capable of driving the slider body to slide along the slideway, the connecting rod mechanism includes a first connecting rod, a second connecting rod and a handle, one end of the second connecting rod is rotatably connected to the base and the other end is connected to the handle, and the two ends of the first connecting rod are rotatably connected to the slider body and the second connecting rod respectively. This structure drives the slider assembly through the second connecting rod and the first connecting rod, and the slider assembly drives the reed material. The movement mode is fast and reliable, making the planing process labor-saving and easy to operate.

[0030] According to an example of the utility model, the multi-blade reed planer further includes a pressure wheel assembly, which includes a pressure wheel frame rotatably connected to the base, a pressure wheel body disposed on the pressure wheel frame and suitable for abutting against the reed material, and a third elastic member connected between the pressure wheel frame and the base, wherein the third elastic member is configured to bias the pressure wheel body toward the positioning portion. The pressure wheel assembly presses the reed material against the slider body to prevent it from sliding or deviating, thereby ensuring the planing accuracy.

[0031] According to an example of the utility model, the pressure wheel frame includes two L-shaped plates symmetrically arranged on both sides of the base and a pressure wheel rod passing through the pressure wheel body, each of the L-shaped plates includes a first part on which the pressure wheel rod is arranged and a second part rotatably connected to the base at its end; there are two third elastic members, one end of each third elastic member is connected to the connection between the first part and the second part, and the other end is connected to the base. This solution uses a simple structure to achieve continuous biasing of the pressure wheel assembly on the reed material, ensuring that it is effectively positioned. BRIEF DESCRIPTION OF THE DRAWINGS

However, it is obvious to those skilled in the art that the implementation of each technical solution of the present invention may not have some of these specific details, or may also be implemented using other equivalent features. It should be understood that the present invention is not limited to the specific embodiments described. On the contrary, it may be considered to implement the present invention using a combination of the features and elements described below.

[0048] In the following, terms such as "first", "second", etc. are used to describe the elements of the present application.

The terms "including" and "having" are used to express an open-ended inclusive meaning, and mean that there may be additional elements / components in addition to the listed elements / components.

[0049] In the description of the present utility model, "first direction X" is used to represent the feeding direction of the reed material 2, and the bidirectional direction in the feeding direction of the reed material can also be referred to as the front-to-back direction. The second direction Y is transverse to the first direction X, and can also be referred to as the left-right direction, which is relative to the front-to-back direction. The third direction Z is perpendicular to the plane where the first direction X and the second direction Y are located, and can also be referred to as the up-down direction.

[0050] Figures 1 to 11 A multi-blade reed planer according to a specific embodiment of the utility model is shown. Figure 1 and Figure 2 As shown, the multi-blade head reed planer according to this embodiment may include a base 1, a slider assembly 3 and a blade assembly 4. A slideway 11 extending along a first direction X is provided in the base 1. The slider assembly 3 may include a slider body 31, on which a positioning portion 32 suitable for positioning the reed material 2 is provided, and the positioning portion 32 may specifically include an arc groove 321 and a stopper 322. The slider body 31 is at least partially accommodated in the slideway 11 and can slide along the slideway 11. Preferably, in this embodiment, the slider body 31 is at least partially accommodated in the slideway, which means that the positioning portion 32 on the slider body 31 can protrude from the slideway 11 in an upward direction to facilitate the positioning and cutting of the reed material; and / or when the reed material 2 is installed on the slider body 31, the rear end of the slider body 31 can extend backward out of the slideway 11; and / or when the slider body 31 slides along the slideway 11 until the reed material 2 is completely planed, the front end of the slider body 31 can extend forward out of the slideway 11. The cutter head assembly 4 is arranged on the base 1, preferably at the front end of the base 1 ( Figure 1 The plurality of cutter heads 41 are arranged in sequence in the first direction X, and are configured to gradually plan the reed material 2 when the slider assembly 3 drives the reed material 2 to pass through each cutter head 41 in sequence. Figure 2 and Fig.12 As shown, the plurality of blades 41 may include a first blade 412, a plurality of middle blades 413 and a tail blade 411 arranged in sequence in the first direction X. The first blade 412 refers to the blade that the reed material 2 first passes through when being fed and planed, and correspondingly, the tail blade 411 refers to the blade that the reed material 2 passes through last.

[0051] Each cutter head 41 is respectively arranged on the base 1 with its two ends in a manner of crossing the slideway 11. Each cutter head 41 includes a cutting portion 414 arranged roughly in the middle of the cutter head 41, and each cutting portion is arranged at a position suitable for planing the reed material 2. The cutting portion 414 may have an arc. It is understood that the arc at this point is the arc formed by the block-shaped portions at both ends of the cutter head 41 being concave toward the slider body 31, that is, downward. This is because the block-shaped portions at both ends of the cutter head 41 are concave. Fig.12 The first blade 412 can be set as a flat blade head with zero curvature, and its role is, for example, to first remove the excess parts on both sides of the reed material 2 to facilitate the subsequent rough planing and fine planing. The surface of the cutting portion 414 of the first blade 412 can be inclined toward the entry point of the reed material 2 to form a Fig.12 The blade of the flat blade head shown. Preferably, the curvatures of the multiple middle blades 413 and the tail blade 411 can be designed to be different. For example, the curvature can be smaller when a shallower depth of planing is required, and the curvature can be larger when a deeper depth of planing is required. Through the structural design of multiple blade heads 41, planing of different depths of reed material can be achieved as required. For example, the process from thicker planing to thinner planing, and from rough trimming to fine trimming can be achieved.

[0052] In order to facilitate the adjustment of the planing height of the tail knife 411 to the reed material 2, Figure 2 , 5 , 9, 10 and Fig.12 As shown, the cutter head assembly 4 may further include an adjusting mechanism 42. The height between the tail knife 411 and the slider body 31 may be adjusted by the adjusting mechanism 42, so that the planing thickness of the tail knife 411 may be flexibly adjusted as required, so that the reed material 2 reaches a desired size.

[0053] Specifically, Figure 5 , Fig. 9 , Fig.10 and Fig.12 As shown, the adjustment mechanism 42 may include a first adjustment member 421 and a second adjustment member 422. The first adjustment member 421 is generally U-shaped. Figure 5 , 9 As shown, the two upper ends of the two legs of the roughly U-shaped structure and the block-shaped parts at both ends of the tail knife 411 are connected to form a whole through fasteners. Fig.10 , 12 As shown, a receiving groove 12 is formed in the base 1, and the first adjusting member 421 and the second adjusting member 422 are arranged in the receiving groove 12. The two upper ends of the two legs of the first adjusting member 421 pass through the receiving groove 12 and are connected to the two ends of the tail knife 411 by fasteners as described above. The first adjusting member 421 can be moved in the receiving groove 12 under the actuation of the second adjusting member 22. Figure 2The third direction Z shown reciprocates, so that the lifting and lowering of the tail knife 411 is adjusted by the movement of the second adjusting member 422 relative to the base 1 .

[0054] More specifically, continue to refer to Figure 5 and Fig. 9 The bottom of the first adjusting member 421 is provided with a plurality of grooves inclined in the same direction in the second direction Y (for example, both are arranged by Figure 5 The first mating surface 4211 and the mating groove 4212 (as shown in the figure) are gradually lowered when the left side extends to the right side. Correspondingly, the top of the second adjusting member 422 is provided with a second mating surface 4221 and a mating block 4222 which are also inclined in the same direction as the first mating surface 4211 and the mating groove 4212 in the second direction Y. The mating block 4222 is embedded in the mating groove 4212, and the second mating surface 4221 is in contact with the first mating surface 4211. When the second adjusting member 422 is adjusted to slide in the accommodating groove 12, the mating block 4222 moves in the mating groove 4212, and under the action of the second mating surface 4221 and the first mating surface 4211, the first adjusting member 421 is raised or can be lowered, thereby driving the tail knife 411 thereon to rise and fall.

[0055] In order to facilitate the adjustment of the position of the second adjusting member 422 outside the base 1, as shown in FIG. Figure 2 , 5 As shown in Figure 12, a cover plate 14 is also provided at the bottom of the receiving groove 12 on the base 1. The cross section of the cover plate 14 is roughly U-shaped, including a bottom and a side edge extending vertically upward from the bottom. A fixing hole (not shown in the figure) can be provided in the bottom to fix the cover plate 14 to the base 1. Threaded holes can also be provided on the two side edges of the cover plate 14. The adjustment mechanism 42 may include two knobs 423, which are respectively threadedly connected to the cover plate 14 through corresponding threaded holes, so as to be relatively arranged on both sides of the cover plate 14 in the second direction Y. The inner ends of the two knobs 423 are respectively abutted against the two sides of the second adjusting member 422 along the second direction Y in the receiving groove 12. When it is necessary to adjust the height of the tail knife 411 relative to the slider body 31, it is only necessary to rotate the knob 423 on one side so that its inner end no longer abuts against the second adjusting member 422, that is, to loosen the second adjusting member 422 in the direction of the knob side so that it has space to move. Then, the knob 423 on the other side is rotated so that the knob 423 pushes the second adjusting member 422 to move until the second adjusting member 422 abuts against the inner end of the knob 423 on the opposite side again, thereby completing the height adjustment of the tail knife 411 .

[0056] In order to ensure the stability of the planing of the reed material 2 by the tail knife 411, Figure 2 and Figure 3 , Figure 6 and Fig.12As shown, the cutter head assembly also includes a pressing block 43 and a first elastic member 44 (such as a spring). The pressing block 43 is arranged between the tail knife 411 and the plurality of intermediate knives 413 in the feeding direction, and is located in front of the tail knife 411 in the feeding direction. The fastener passes through the first elastic member 44 and the pressing block 43 and is fixed on the base, and the first elastic member 44 is abutted against the fastener and the pressing block 43 at both ends, so that it has a certain elastic potential energy and is biased on the pressing block 43, thereby ensuring that the reed material 2 is pressed against the slider body 31, ensuring the stability of the planing of the reed material 2 by the tail knife 411, and better ensuring the planing accuracy. It should be noted that although the shape of the pressing block shown in the figure is that the middle part has a downward arc, the pressing block does not have a cutting function, and its shape can also be other shapes, as long as the reed material can be pressed.

[0057] In a further embodiment, Figure 2 , Figure 3 and Fig.12 As shown, the cutter head assembly may further include two end plates 45 respectively connected to both sides of the base 1. One of the end plates 45 abuts against one end of the pressing block 43, the plurality of intermediate knives 413 and the first knife 412, and the other end plate 45 abuts against the other end of the pressing block 43, the plurality of intermediate knives 413 and the first knife 412. Thus, the pressing block 43, the plurality of intermediate knives 413 and the first knife 412 are stably limited in the second direction Y.

[0058] Further, in an embodiment of the present utility model, if Figure 2 As shown, the positioning portion provided on the slider body 31 may specifically include an arcuate groove 321 and a stopper 322. The arcuate groove 321 extends along the first direction X at the top of the slider body 31 and its shape is adapted to the curvature of the outer periphery of the reed material 2, so that the outer periphery of the reed material 2 can be fitted with the arcuate groove 321 in surface contact when it is pressed against the slider body 31. The stopper 322 abuts against the end of the reed material 2 away from the cutter head assembly 4, thereby preventing the reed material 2 from retreating backward when the reed material 2 enters the cutter head assembly 4 for planing and stress.

[0059] Further, refer to Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, a groove 311 connected to the arc groove 321 is also formed on the slider body 31. The slider assembly 3 may also include a second elastic member 33, and the second elastic member 33 and the stopper 322 are accommodated in the groove 311 together, and the second elastic member 33 is arranged between the stopper 322 and the bottom of the groove 311, so that the stopper 322 can be in an extended state and a retracted state relative to the groove 311 under the action of the second elastic member 33. In the extended state of the stopper 322, the second elastic member 33 generates a bias on the stopper 322, and the top side end of the stopper 322 extends into the arc groove 321, and is in contact with the rear end ( Figure 1 , 2 When the stopper 322 is retracted, the stopper 322 is pressed downward and partially retracted into the groove 311, so that the top end of the stopper 322 is located below the plurality of cutter heads 41 and the pressing block 43 in height and can also play a role of resisting the rear end of the reed material 2 during the planing process of the reed material 2.

[0060] Furthermore, if Figure 2 , Figure 3 and Fig.12 As shown, the cutter head assembly 4 may also include two lining plates 46. The two lining plates 46 are relatively arranged on both sides of the base 1 corresponding to the slideway 11 in the second direction Y. The lining plates 46 extend along the first direction X and are arranged between the multiple intermediate knives 413 and the first knives 412 in the multiple cutter heads 41 and the base 1. The lining plates 46 can play many roles, which will be described in detail below. First, when the stopper 322 is driven by the slider body 31 and passes through the cutter head assembly 4 to push the reed material 2 to be planed, the lining plates 46 play the role of pressing the stopper 322 down to the retracted state, so that the stopper 322 can smoothly pass through the cutter head assembly 4 and continue to push the reed material 2. Specifically, two positioning blocks 323 corresponding to the two lining plates 46 are arranged on the stopper 322. The two positioning blocks 323 are relatively arranged in the second direction Y and are integrally formed on both sides of the stopper 322. The stopper 323 can be pressed down to a retracted state by the lining plate 46 and the positioning block 323 abutting against and cooperating with each other.

[0061] like Figure 2 and 12 As shown, the end of the lining plate 46 facing the stopper 322 is provided with a first inclined surface 461 inclined toward the bottom surface of the lining plate 46 in the first direction X. Correspondingly, the end of the positioning block 323 facing the lining plate 46 is provided with a second inclined surface 3231 (such as Figure 8Thus, when the stopper 322 passes through the lining plate 46, the stopper 322 enters under the lining plate 46 through the cooperation between the first inclined surface 461 and the second inclined surface 3231, moves downward and partially retracts into the groove 411.

[0062] refer to Fig.12 As shown, the slider body 31 is provided with stepped limiting portions 312 on both sides corresponding to the arc groove 321. As another function of the lining plate 46, the lining plate 46 extends from the top of the base 1 to the upper side of the limiting portion 312 and engages with it, that is, presses on the limiting portion 312, thereby preventing the slider body 31 from moving upward and limiting the slider body 31 in the slideway 11.

[0063] In order to prevent the stopper 322 from coming out of the groove 311 and to limit the protruding height of the stopper 322 relative to the arc groove 321, refer to Figure 2 , Figure 7 and Figure 8 As shown, the slider assembly 3 may further include a limiting member 34 disposed in the groove 311 together with the stopper 322. The limiting member 34 is preferably disposed at the rear side of the stopper 322 in the first direction X. A limiting groove 341 is disposed in the limiting member 34. A protrusion 324 protruding from the surface of the stopper 322 is disposed on one side of the stopper 322 close to the limiting member 34. The protrusion 324 is accommodated in the limiting groove 341 and can slide in the limiting groove 341. When the stopper 322 is in the extended state, the protrusion 324 abuts against the top wall of the limiting groove 341, thereby limiting the extended height of the stopper 322 and preventing the stopper 322 from escaping from the groove 311.

[0064] Further, refer to Figure 1 and Figure 2 As shown, the multi-blade head reed planer may also include a connecting rod mechanism 5 capable of driving the slider body 31 to slide along the slideway 11. Specifically, the connecting rod mechanism may include a first connecting rod 51, a second connecting rod 52 and a handle 53. One end of the second connecting rod 52 is rotatably connected to the base 1 and the other end is connected to the handle 53. One end of the first connecting rod 51 is rotatably connected to the end of the slider body 31 away from the cutter head assembly 4, and the other end is rotatably connected to the second connecting rod 52. By pulling the handle 53, the second connecting rod 52 can rotate with the connection point between the second connecting rod 52 and the base 1 as the rotation center, and thereby the slider body 31 is pushed to move along the first direction X through the first connecting rod 51. In some other embodiments, the slider body 31 can also be driven by a gear transmission mechanism and a crank, or an electric motor can be used to achieve automatic drive.

[0065] Furthermore, the multi-blade head reed planer may also include a pressure wheel assembly 6, such as Figure 1 , Figure 2 , Fig.11 and Fig.12 As shown. The pressure wheel assembly 6 may include a pressure wheel frame 61, a pressure wheel body 62 and a third elastic member (such as a tension spring, not shown in the figure). The pressure wheel frame 61 is rotatably connected to the base 1. The pressure wheel body 62 is rotatably connected to the pressure wheel frame 61 and its wheel surface is suitable for abutting against the upper surface of the reed material 2. The third elastic member is connected between the pressure wheel frame 61 and the base 1, and is capable of maintaining a certain tension to bias the pressure wheel body 62 toward the positioning portion 32 on the slider body 31, so that the wheel surface of the pressure wheel body 62 can be kept against the reed material 2 during the planing process of the reed material 2 to prevent the reed material 2 from moving and deviating.

[0066] As a preferred specific structure of the pressure wheel frame 61, refer to Fig.11 and 12 The pressure wheel frame 61 may include two L-shaped plates 611 symmetrically arranged on both sides of the base 1 in the second direction Y and a pressure wheel rod 612 passing through the pressure wheel body 62. Each L-shaped plate 611 may include a first part 6111 and a second part 6112. The pressure wheel rod 612 may be arranged in the middle of the first part 6111. One end of the second part 6112 away from the first part 6111 is rotatably connected to the base 1. Thus, the pressure wheel body 62 can be rotatably arranged above the slider body 31. A first connecting hole 6113 may be arranged at the connection between the first part 6111 and the second part 6112, and the base 1 is correspondingly provided with a second connecting hole 13 at its side, and the second connecting hole may be, for example, a threaded hole, in which a threaded fastener is arranged. One end of the third elastic member is connected to the fastener, and the other end passes through the first connecting hole 6113 and is fixed on the L-shaped plate 611.

[0067] For example, Figure 4 As shown, a hollow portion 16 may be formed in the base 1 to reduce the weight of the entire reed planer. A bottom plate 15 connected to the base 1 may be provided at the lower portion of the hollow portion 16 to improve the stability of the base 1 when placed. Similarly, through holes may be formed in the slider body 31, the first connecting rod 51, the second connecting rod 52 and other components to reduce the weight of the entire reed planer.

[0068] The working process of the multi-blade reed planer according to the utility model is briefly described below. The handle 53 is pulled away from the blade assembly 4, so that the slider body 31 retreats along the slide 11 and exposes the arc groove 321. The reed material 2 is placed in the arc groove 321 with its outer peripheral surface facing the slider body 31, and the tail end of the reed material 2 abuts against the stopper 322. The handle 53 is pulled in the first direction X, and the slider body 31 is pushed to move in the first direction X via the first connecting rod 51. The reed material 2 first passes through the pressure wheel assembly 6, and the reed material 2 can be tightly pressed in the arc groove 321 through the pressure wheel body 62, thereby keeping the reed material 2 stable during the planing process. Then the reed material 2 is planed by the first knife 412, and the redundant parts on both sides and the redundant parts in the height direction are removed, and the reed material 2 is gradually planed from coarse to fine when passing through multiple intermediate knives 411 and the tail knife 411. As the reed 2 gradually becomes thinner during the planing process, when the stopper 322 moves to the lining plate 46 with the slider body 31, the second inclined surface 3231 of the positioning block 323 on the stopper 322 is guided by the first inclined surface 461 of the lining plate 46, and the stopper 322 is pressed down to partially retract the stopper 322 into the groove 311, thereby allowing the stopper 322 to continue to stop the reed 2 to prevent it from retreating, and also to prevent the stopper 322 from interfering with the cutter head assembly 4. Continue to push the handle 53 until the end of the entire reed 2 passes through the tail knife 411, and the planing of the reed 2 is completed to obtain a reed flake.

[0069] As described above, according to the multi-blade head reed planer of the utility model, when the slider body 31 drives the reed material 2 to pass through the multiple blades 41 in sequence, the multiple blade heads 41 plane the reed material 2 in sequence. The multi-blade head setting gives different blades different cutting parameters, and the process from rough planing to fine planing can be achieved in one feed, which greatly improves the planing efficiency and the life of the blade.

Other embodiments of the utility model will be apparent to those skilled in the art from the practice of the utility model disclosed in this specification.
