[0002] With the development of the textile industry and the continuous improvement of living standards, differentiated and functional textiles have become an important direction for industrial development. As an important accessory of textile machinery, the reed is mainly used to determine the distribution density of warp yarns and the width of fabrics, and to beat the weft yarns in the shed to the weft during beating, which directly determines the type and function of textiles. The reed is made by winding and connecting reed teeth of the same length and thickness using steel wires of the same specifications.

[0003] In practice, the reed teeth are obtained by cutting the steel strip with a feeder. The feeding method of the feeder not only affects the roughness and flatness of the reed tooth surface, but also has an important impact on the service life and reliability of the reed teeth. The existing feeding methods mainly include roller type, pneumatic clamping type, etc. The roller type feeding method is easy to squeeze the steel strip and cause the reed tooth surface to wear.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the embodiments of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0031] Please refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a feeding machine for processing reed teeth, including a driving mechanism 1, a feeding mechanism 2, a steel strip cutting mechanism 3 and a conveying mechanism 4.

[0032] like Figure 1 and Figure 2 As shown, the driving mechanism 1 includes a frame 11 , a driving assembly 12 and a first main shaft system 13 .

[0033] The rack 11 includes two first mounting plates 111 arranged in parallel. Of course, the rack 11 also includes two fixing plates 112. The two fixing plates 112 are arranged on both sides of the bottom of the first mounting plate 111, and both sides of the fixing plates 112 extend out of the sides of the first mounting plate 111. The rack 11 can be fixed to other components by the fixing plates 112, thereby facilitating the fixing of the rack 11. In addition, the fixing plates 112 play a role in pre-fixing the first mounting plates 111, so that the distance between the two first mounting plates 111 is determined, the rack 11 is integrated, and the subsequent installation of the rack 11 is further facilitated.

[0034] like Figure 1 As shown, at least one of the first mounting plates 111 is provided with a window recessed from top to bottom, so as to facilitate the installation of the components arranged between the two first mounting plates 111 and reserve sufficient activity space for the connecting rod assembly 22. At the same time, it is convenient to observe the working condition of the components and subsequent maintenance.

[0035] The first main shaft system 13 is inserted through the two first mounting plates 111. The driving assembly 12 is sleeved in the middle of the first main shaft system 13, so that when the driving assembly 12 is working, it can drive the first main shaft system 13 to rotate.

[0036] Continue to refer to Figure 1 and Figure 2 As shown, the feeding mechanism 2 includes a first crank 21 , a connecting rod assembly 22 and a clamping assembly 23 .

[0037] The first end of the first main shaft system 13 is sleeved with a first crank 21, and the first end of the first main shaft system 13 is connected to the first crank 21 via a flat key. Figure 1 As shown, the first end of the first main shaft system 13 extends out of the first mounting plate 111, and the first crank 21 is located outside the first mounting plate 111. The first mounting plate 111 isolates the first crank 21 and the driving assembly 12, thereby reducing the possibility of mutual interference between the first crank 21 and the driving assembly 12 during operation. In addition, the size of the entire feeder can be reduced.

[0038] like Figure 1 and Figure 2 As shown, the first end of the connecting rod assembly 22 is connected to the first crank 21, and the second end is connected to the clamping assembly 23. The first crank 21 drives the connecting rod assembly 22 to move while driving the clamping assembly 23 to move, so that the clamping assembly 23 is configured to clamp the steel belt 6 at a preset position and convey the steel belt 6 when moving forward, and release the steel belt 6 when moving backward. The preset position is the position where the clamping assembly 23 clamps the steel belt 6, and then the steel belt 6 is clamped and pushed forward and cut to obtain the reed teeth of the required length.

[0039] The first crank 21 has holes at different distances from its own center, so that the holes at different positions are connected to the connecting rod assembly 22 to adjust the preset clamping position of the clamping assembly 23, so that the feeding length can be adjusted. For example, the first crank 21 has holes at 57.9mm, 81.9mm and 100.7mm from its own center, and the lengths of the corresponding cut reed teeth are 80mm, 120mm and 160mm.

[0040] like Figure 2 and Figure 5 As shown, the steel strip cutting mechanism 3 includes a second mounting plate 31 , a second main shaft system 32 , a synchronous rotation assembly 33 , a second crank 34 and a tool assembly 35 .

[0041] The second mounting plate 31 is fixedly mounted on the top of the feeding mechanism 2 by welding. The second mounting plate 31 plays the role of mounting and fixing other components of the steel strip cutting mechanism 3. Specifically, the second mounting plate 31 is fixedly mounted on the top of a first mounting plate 111 by welding.

[0042] The second main shaft system 32 is inserted through the upper portion of the second mounting plate 31 , the second crank 34 is sleeved on the first end, and the first end of the synchronous rotation assembly 33 is sleeved on the second end.

[0043] The second end of the synchronous rotation component 33 is sleeved on the second end of the first main shaft system 13. The second end of the first main shaft system 13 extends out of the first mounting plate 111, and the synchronous rotation component 33 is located outside the first mounting plate 111. The first mounting plate 111 isolates the synchronous rotation component 33 and the driving component 12, thereby reducing the possibility of mutual interference between the synchronous rotation component 33 and the driving component 12 during operation. In addition, the size of the entire blanking machine can be reduced.

[0044] The upper end of the cutter assembly 35 is connected to the second crank 34 , so that the movement of the second crank 34 drives the cutter assembly 35 to move up and down, away from the steel strip 6 or cut the steel strip 6 .

[0045] When the synchronous rotation assembly 33 is installed, the intersection of the central axis of the first main axis system 13 and the surface of the first crank 21, and the connection point of the first end of the connecting rod assembly 22 and the surface of the first crank 21 are the first straight line, and the intersection of the central axis of the second main axis system 32 and the surface of the second crank 34, and the connection point of the upper end of the tool assembly 35 and the surface of the second crank 34 are the second straight line. The first straight line is staggered clockwise by 133° to 143° (138°±5°) relative to the second straight line. The plane where the first straight line is located is parallel to the plane where the second straight line is located, and the first straight line and the second straight line are skew lines, and the angle between the skew lines is 133° to 143°.

[0046] The conveying mechanism 4 is arranged below the steel belt cutting mechanism 3 and is configured to convey the reed teeth. After the steel belt 6 is cut into reed teeth, the transmission mechanism conveys the reed teeth to the workers below for packaging.

[0047] The blanking machine for machining reed teeth provided by the embodiment of the present invention, in actual operation, the first main shaft system 13 of the driving mechanism 1 is inserted through the two first mounting plates 111 of the frame 11, the driving assembly 12 is sleeved in the middle of the first main shaft system 13, the first crank 21 of the feeding mechanism 2 is sleeved on the first end of the first main shaft system 13, and the second end of the synchronous rotation assembly 33 is sleeved on the second end of the first main shaft system 13. The first end of the connecting rod assembly 22 is connected to the first crank 21, and the second end is connected to the clamping assembly 23. The first mounting plate 111 is fixedly mounted above the feeding mechanism 2, the second main shaft system 32 is inserted through the upper part of the second mounting plate 31, the first end of the second main shaft system 32 is sleeved with the second crank 34, and the second end is sleeved with the first end of the synchronous rotation assembly 33. The upper end of the tool assembly 35 is connected to the second crank 34. In the actual working process, the driving assembly 12 drives the first main shaft system 13 to rotate, and the first main shaft system 13 drives the first crank 21 and the first end of the synchronous rotation assembly 33 to rotate together. During the rotation of the first crank 21, the connecting rod assembly 22 is driven forward. At this time, the connecting rod assembly 22 always presses the preset position of the steel belt 6 and drives the steel belt 6 to be transported forward to the required length of cutting. The first crank 21 continues to rotate to drive the connecting rod assembly 22 to move, and the connecting rod assembly 22 drives the clamping assembly 23 to retreat. At this time, the clamping assembly 23 releases the steel belt 6 and retreats to the initial position by itself to press the steel belt 6 again at the next preset position. Since the synchronous rotation component 33 is installed, the intersection of the central axis of the first main shaft system 13 and the surface of the first crank 21, and the line connecting the first end of the connecting rod assembly 22 and the surface of the first crank 21 is the first straight line, and the intersection of the central axis of the second main shaft system 32 and the surface of the second crank 34, and the line connecting the upper end of the tool assembly 35 and the surface of the second crank 34 is the second straight line. The first straight line is offset by 133° to 143° clockwise relative to the second straight line. The driving component 12 drives the first main shaft system 13 to rotate, and the first main shaft system 13 simultaneously drives the first crank 21 and the synchronous rotation component 33 to rotate. Therefore, in the process of retraction of the connecting rod assembly 22, the driving component 12 simultaneously drives the synchronous rotation component 33 to move, the synchronous rotation component 33 drives the second main shaft system 32 to rotate, the second main shaft system 32 drives the second crank 34 to rotate, and the second crank 34 drives the tool assembly 35 to move downward to cut the steel belt 6 to obtain the reed teeth. When the clamping assembly 23 moves forward, the cutter assembly 35 rises synchronously, realizing the linkage control of the clamping assembly 23 clamping the steel belt 6 to the preset position and conveying the steel belt 6 and the cutter assembly 35 cutting the steel belt 6 under the action of a driving assembly 12, and the coordinated movement realizes the sequential action of feeding and cutting the steel belt 6, and has a simple structure and is easy to debug and replace. By pressing and conveying the steel belt 6 by the feeding mechanism 2, it can ensure that the surface damage of the processed reed teeth is small and the feeding length is accurate.

[0048] The feeding mechanism 2 also includes a sliding plate 24. The sliding plate 24 is disposed between the two first mounting plates 111, fixedly disposed on the side of one of the first mounting plates 111, and the upper surface is parallel to the top surface of the first mounting plate 111. The clamping assembly 23 is disposed on the sliding plate 24 and can slide along the sliding plate 24. The sliding plate 24 can provide an upward supporting force to the clamping assembly 23, and can also guide the clamping assembly 23 during the forward or backward movement of the clamping assembly 23. Preferably, a guide block can also be provided at the bottom of the clamping assembly 23, and a guide groove can be provided on the top surface of the sliding plate 24, and the guide block can be clamped in the guide groove, so that the clamping assembly 23 can move linearly along the direction of the guide groove, and the movement is more stable.

[0049] Further, as shown in FIG2 , the blanking machine for processing reed teeth further comprises a placing frame 5. The placing frame 5 comprises supporting legs 51, a top plate 52, a placing plate 54 and a connecting rod 55.

[0050] The legs 51 include four legs, and the four legs 51 are arranged in a rectangular array. The top plate 52 is arranged on the top of the four legs 51. The connecting rods 55 include four legs, and one connecting rod 55 is arranged between two adjacent legs 51.

[0051] The placement plate 54 is arranged on two connecting rods 55 at opposite positions. A through hole 53 is arranged on the top plate 52. One end of the drive assembly 12 is arranged on the placement plate 54, and the other end is sleeved on the first main shaft system 13, and the middle part passes through the through hole 53, so as to facilitate the installation of the drive assembly 12. The through hole 53 allows the drive assembly 12 to pass through, so that the drive assembly 12 can be stably installed, adapted to be installed with other components, and work smoothly.

[0052] Optional, such as Figure 2 As shown, the driving assembly 12 includes a first motor 121, a driving pulley 122, a driven pulley 123 and a transmission belt 124. The driving pulley 122 is sleeved on the output shaft of the first motor 121. The driven pulley 123 is sleeved on the middle part of the first main shaft system 13. The transmission belt 124 is sleeved on the driving pulley 122 and the driven pulley 123. The transmission belt 124 can be a V-belt. V-belt transmission transmits power by generating friction between the two sides of the V-belt and the side of the wheel groove. Compared with flat belt transmission, the friction of V-belt transmission is greater, so it can transmit greater power. The V-belt has a compact structure and is a jointless transmission belt, so the transmission is smoother.

[0053] In practice, the first motor 121 drives the driving pulley 122 to rotate clockwise, thereby driving the transmission belt 124 and the driven pulley 123 to rotate. Since the driven pulley 123 is sleeved on the middle of the first main shaft system 13, the first motor 121 drives the first main shaft system 13 to rotate clockwise, thereby realizing the reciprocating conveying of the steel belt 6. The driving assembly 12 provided in the embodiment of the present application can stably transmit kinetic energy to drive the first main shaft system 13 to rotate, and then simultaneously drive the first crank 21 and the synchronous rotation assembly 33 arranged at both ends of the first main shaft system 13 to move clockwise. The first main shaft system 13 rotates one circle to complete the conveying and cutting of the steel belt 6.

[0054] like Figure 7 As shown, the synchronous rotation assembly 33 includes a driving synchronous pulley 331, a driven synchronous pulley 332 and a synchronous belt 333. The driving synchronous pulley 331 is sleeved on the second end of the first main shaft system 13 (the driving synchronous pulley 331 is connected to the second end of the first main shaft system 13 by a flat key), the driven synchronous pulley 332 is sleeved on the second end of the second main shaft system 32, and the synchronous belt 333 is sleeved on the driving synchronous pulley 331 and the driven synchronous pulley 332. The driving synchronous pulley 331 and the driven synchronous pulley 332 are of the same size, and pulley retaining rings are installed at both ends.

[0055] When the first main shaft system 13 rotates, the driving synchronous pulley 331 is driven to rotate, thereby driving the synchronous belt 333 and the driven synchronous pulley 332 to rotate. Since the driven synchronous pulley 332 is sleeved on the second end of the second main shaft system 32, the driven synchronous pulley 332 drives the second main shaft system 32 to rotate. The synchronous rotation assembly 33 provided in the embodiment of the present application can stably transmit kinetic energy to drive the second main shaft system 32 to rotate.

[0056] Furthermore, if Figure 2 As shown, the connecting rod assembly 22 includes a first connecting rod 221 , a second connecting rod 222 , a third connecting rod 223 , a fourth connecting rod 224 and a fifth connecting rod 225 .

[0057] The first end of the first connecting rod 221 is rotatably connected to the first crank 21 (specifically, a first connecting column 226 is fixedly provided on the first crank 21, and the first end of the first connecting rod 221 is rotatably connected to the first connecting column 226), and the second end is rotatably connected to the first end of the third connecting rod 223.

[0058] The first end of the second connecting rod 222 is rotatably connected to the middle of the first connecting rod 221, and the second end is rotatably connected to the first mounting plate 111. Specifically, a second connecting column 227 is fixedly provided at the middle of the first connecting rod 221, and a third connecting column 228 is fixedly provided on the first mounting plate 111 at the upper left of the first main shaft system 13. The first end of the second connecting rod 222 is rotatably connected to the second connecting column 227, and the second end is rotatably connected to the third connecting column 228.

[0059] The second end of the third connecting rod 223 is rotatably connected to the first end of the fourth connecting rod 224. The second end of the fourth connecting rod 224 is rotatably connected to the clamping assembly 23.

[0060] The first end of the fifth connecting rod 225 is rotatably connected to the middle part of the fourth connecting rod 224 (specifically, a fourth connecting column 229 is fixedly provided in the middle part of the fourth connecting rod 224, and the first end of the fifth connecting rod 225 is rotatably connected to the fourth connecting column 229), and the second end is rotatably connected to the clamping assembly 23.

[0061] The connecting rod assembly 22 provided in the embodiment of the present application drives the first connecting rod 221, the second connecting rod 222, the third connecting rod 223, the fourth connecting rod 224 and the fifth connecting rod 225 to work in linkage when the first crank 21 rotates, so that the connecting rod assembly 22 drives the clamping assembly 23 to always clamp the steel belt 6 at a preset position and convey the steel belt 6 when it drives it forward, and automatically releases the steel belt 6 when it retreats, and does not return the steel belt 6, thereby realizing adjustable displacement of multiple mechanisms in series, and realizing clamping and feeding of the steel belt 6. Compared with the traditional roller-type feeding method of extruding the steel belt for feeding, the feeding machine only squeezes the non-working areas at both ends of the reed teeth, does not damage the surface of the working area of ​​the reed teeth, and can realize fast and accurate feeding of the steel belt 6.

[0062] Optional, such as Figure 3 and Figure 4 As shown, the clamping assembly 23 includes a clamping seat 231, a first clamping link 232 and a second clamping link 233. The clamping seat 231 includes a first sheet 2311 and a second sheet 2312 which are arranged perpendicular to each other.

[0063] The second plate 2312 is connected to the second end of the connecting rod assembly 22 . Specifically, the second plate 2312 is connected to the second end of the fourth connecting rod 224 of the connecting rod assembly 22 .

[0064] The first end of the first clamping link 232 is rotationally connected to the connecting rod assembly 22 (specifically, the first end of the first clamping link 232 is rotationally connected to the fifth connecting rod 225 of the connecting rod assembly 22), the second end is fixedly connected to the second clamping link 233, and the length extension direction of the first clamping link 232 is perpendicular to the length extension direction of the second clamping link 233.

[0065] The steel belt 6 is arranged on the upper surface of the first sheet 2311 , and the second clamping link 233 can clamp the steel belt 6 at a preset position and convey the steel belt 6 when advancing, and release the steel belt 6 when retreating. The middle part of the first clamping link 232 is fixedly arranged on the second sheet 2312 .

[0066] The clamping assembly 23 provided in the embodiment of the present application, the second end of the fourth link 224 of the connecting rod assembly 22 is connected to the second plate 2312, and the second end of the fifth link 225 is connected to the first end of the first clamping link 232. Therefore, during the movement of the connecting rod assembly 22, the second clamping link 233 fixedly connected to the second end of the first clamping link 232 can always clamp the steel belt 6 at a preset position and convey the steel belt 6 when moving forward, and release the steel belt 6 when moving backward.

[0067] Furthermore, the first clamping link 232 includes a first sub-rod 2321 and a second sub-rod 2322 (such as Figure 3 As shown, the first sub-rod 2321 and the second sub-rod 2322 are integrally formed), and the angle between the central axis of the first sub-rod 2321 and the second sub-rod 2322 is an obtuse angle. One end of the first sub-rod 2321 is connected to the second clamping link 233, and one end of the second sub-rod 2322 is connected to the fifth link 225 of the connecting rod assembly 22. The first clamping link 232 is arranged to protrude upward. Adaptively, the height of at least the middle part of the second sheet 2312 is higher than other positions, so that the middle part of the first clamping link 232 is fixed, so that the center of gravity position of the clamping assembly 23 is more suitable, so that the connecting rod assembly 22 is connected to the first end of the first clamping link 232 and the second sheet 2312, and the connection position is lower than the middle part, so that the connecting rod assembly 22 can push the clamping assembly 23 at a uniform speed and stably. The height of at least the middle part of the second sheet 2312 is higher than other positions to better adapt to the motion trajectory of the connecting rod assembly 22, so that the clamping assembly 23 can better complete various actions.

[0068] Continue to refer to Figure 3 and Figure 4 As shown, the clamping assembly 23 also includes a fixing ear 234, a clamp 235 and a fixing member 236. Two fixing ears 234 are arranged in parallel below the second clamping link 233. The clamp 235 is U-shaped, and the two side plates are respectively fixed to the fixing ears 234 at the corresponding positions by the fixing members 236 (specifically, the two side plates are respectively fixed to the fixing ears 234 at the corresponding positions by a bolt). The first sheet 2311 is provided with a notch that is recessed downward along the upper surface. The steel belt 6 is arranged in the notch.

[0069] The notch can be provided to press the clamp 235 downward to position it, and can also position the steel strip 6 to prevent the steel strip 6 from swinging during transportation. The fixing member 236 can be a bolt. The clamp 235 can rotate relative to the fixing member 236, so that the clamp 235 can adjust the angle and height to adapt to steel strips 6 of different thicknesses.

[0070] Furthermore, if Figure 1 and Figure 2As shown, the blanking machine for processing reed teeth also includes a steel band clamp mechanism 7. The steel band clamp mechanism 7 includes a second clamping groove 71, a sealing plate 72 and at least two L-plates 73. At least two L-plates 73 are fixedly arranged in a linear array on the inner side of the mounting plate of the driving mechanism 1. The second clamping groove 71 is arranged on the L-plate 73. The sealing plate 72 is sealed above the second clamping groove 71. The steel sheet is arranged in the second clamping groove 71 and can move along the second clamping groove 71. The setting of the second clamping groove 71 can position the steel sheet during movement and prevent the steel band 6 from swinging during the cutting process. The setting of the second clamping groove 71 and the sealing plate 72 can prevent the steel band 6 from falling out of the second clamping groove 71. At the same time, during the process of dragging the steel band 6 in the inner cavity formed by the second clamping groove 71 and the sealing plate 72, the steel band 6 can be shaped to make the steel band 6 flat, which is convenient for the subsequent cutting of the steel band 6.

[0071] like Figure 5 As shown, the tool assembly 35 includes a tool fixing frame 351 , a punching knife 352 , a positioning block 353 and a first slot 354 .

[0072] The upper end of the tool fixing frame 351 is connected to the second crank 34. The lower end of the tool fixing frame 351 is provided with a punching knife 352. The tool fixing frame 351 includes a tool connecting rod 3511, a connecting vertical plate 3512, a first connecting L plate 3513 and a second connecting L plate 3514. The first end of the tool connecting rod 3511 is connected to the second crank 34, and the second end is connected to the first end of the connecting vertical plate 3512. The second end of the connecting vertical plate 3512 is connected to the vertical plate of the first connecting L plate 3513, the horizontal plate of the first connecting L plate 3513 is connected to the horizontal plate of the second connecting L plate 3514, and the punching knife 352 is provided on the vertical plate of the second connecting L plate 3514. The tool fixing frame 351 provided in the embodiment of the present application increases the distance between the tool fixing frame 351 and the second mounting plate 31 through the provision of the first connecting L plate 3513 and the second connecting L plate 3514, so as to facilitate the subsequent provision of the guide rail 355 and the slider 356. At the same time, the tool is finally fixed to the vertical plate of the second connecting L plate 3514, providing a larger fixing surface for the punching knife 352, so that the tool is fixed more firmly. At the same time, the structure of the entire tool fixing frame 351 is light, which can reduce the driving force required for the tool fixing frame 351 to rise and fall.

[0073] The positioning block 353 is disposed below the tool fixing bracket 351. Specifically, the positioning block 353 is fixed on the sliding plate 24, and the positioning block 353 is perpendicular to the sliding plate 24 and the first mounting plate 111. The first clamping groove 354 is fixed on the positioning block 353 and is configured to clamp the steel belt 6.

[0074] The arrangement of the positioning block 353 and the first clamping groove 354 can further fix the steel strip 6, so that the steel strip 6 is conveniently cut by the punch 352. Since the positioning block 353 is directly fixed, the arrangement of the first clamping groove 354 can facilitate the clamping of the steel strip 6 and then fix it to the positioning block 353. This facilitates the clamping and positioning of the steel strip 6.

[0075] Optional, such as Fig. 9 The cutting edge of the punch 352 is inclined, thereby facilitating cutting of the steel strip 6 and saving effort.

[0076] Among them, Figure 2 As shown, the tool connecting rod 3511, the first connecting rod 221, the second connecting rod 222, the fourth connecting rod 224 and the fifth connecting rod 225 all include a rod body 221A and two rod end joint bearings 221B. A rod end joint bearing 221B is respectively provided at both ends of the rod body 221A through a thread and a pin. The rod end joint bearing 221B of the first connecting rod 221, the second connecting rod 222 and the fourth connecting rod 224 is φ10, and the rod end joint bearing 221B of the tool connecting rod 3511 and the fifth connecting rod 225 is φ6.

[0077] Further, continue to refer to Figure 5 As shown, the tool assembly 35 further includes a guide rail 355 and a slider 356. The guide rail 355 is disposed on the second mounting plate 31, extends downward, and is clamped on the slider 356. The slider 356 is fixed to the tool fixing frame 351. Specifically, the slider 356 is fixed to the connecting vertical plate 3512 of the tool fixing frame 351. During the rising and falling process of the tool assembly 35, the guide rail 355 and the slider 356 can guide the tool fixing frame 351.

[0078] like Figure 5 As shown, the cutter assembly 35 also includes an extension piece 357 and a pressure head 358. One end of the extension piece 357 is arranged on the cutter fixing frame 351. The upper end of the pressure head 358 is arranged on the extension piece 357, and when the steel strip cutting mechanism 3 is about to cut the steel strip 6, the lower end of the pressure head 358 lightly touches the steel strip 6, so that the two ends of the cut part of the steel strip 6 are respectively fixed by the first clamping groove 354 and the pressure head 358, which facilitates the cutter assembly 35 to cut the steel strip 6, and also enables the cut reed to fall smoothly on the conveying mechanism 4. Further, a long groove is arranged at the position where the extension piece 357 connects to the pressure head 358, and the upper end of the pressure head 358 can slide along the long groove, so that the position where the lower end of the pressure head 358 lightly touches the steel strip 6 can be adjusted.

[0079] Optional, such as Figure 7 and Figure 8As shown, the conveying mechanism 4 includes a profile frame 41, a driving member 42, a first main shaft 43, a second main shaft 44 and a conveyor belt 45. The profile frame 41 is a hexahedron. The first main shaft 43 and the second main shaft 44 are arranged parallel to the profile frame 41. The output shaft of the driving member 42 is connected to the first main shaft 43. The conveyor belt 45 is sleeved on the first main shaft 43 and the second main shaft 44.

[0080] The driving member 42 is a second motor. When the driving member 42 is working, it drives the first main shaft 43 to rotate, and the first main shaft 43 drives the second main shaft 44 and the conveyor belt 45 to rotate. When the reed teeth cut by the steel belt 6 fall on the conveyor belt 45, the conveyor belt 45 conveys the reed teeth to the workers for packaging.

[0081] The feeding machine for processing reed teeth provided in the embodiment of the present application is also suitable for feeding and cutting other strip materials.
