[0003] After searching, the patent document with the cited publication number CN218904757U and the publication date April 25, 2023, named Needle Sharpening Equipment, includes a machine body, a turntable is installed on the top of the machine body, and a fine grinding mechanism and a polishing mechanism are also arranged on the top of the machine body, and the fine grinding mechanism and the polishing mechanism are surrounded by the turntable; the fine grinding mechanism includes an acupuncture needle detection tube, and a grinding block is arranged inside the acupuncture needle detection tube, and a cylindrical sleeve is evenly arranged on the outer wall of the acupuncture needle detection tube, and a supply branch pipe is fixed to one end of the cylindrical sleeve by welding, and a supply pipe is fixed to one end of the supply branch pipe by welding, and one end of the supply pipe is connected with the ingredient shell, and a pumping pump is installed on the supply pipe. In the above embodiment, when the acupuncture needle enters the flexible rubber hose, if there are surface defects on the acupuncture needle, the viscous friction agent in the friction agent temporary storage chamber is sucked into the interior through the flow channel, so as to facilitate the judgment of the uniformity of the acupuncture needle and to coat more viscous friction agent on its surface to facilitate the polishing of the surrounding surface. The external translation mechanism and rotation mechanism are used to drive the polishing, so that the potholes can be eliminated.

[0004] However, the above embodiment still has the following defects:

[0005] In the above embodiment, the acupuncture needles need to be delivered to the flexible rubber hose in sequence during sharpening. Since the production volume of acupuncture needles is usually large, this sharpening method will waste a lot of working time and require manual operation by employees, thereby reducing the degree of automation and the fluency of work. Summary of the invention

[0011] Furthermore, a second slope is provided on the top inner wall of the supply box outlet, and the height of the second slope on one side close to the supply box outlet opening is lower than that on the other side.

[0012] Furthermore, two groups of side mounting plates are symmetrically provided at the edges of both sides of the top of the first feed port, a middle cross bar is provided between the two groups of side mounting plates, and two groups of side cross bars are provided on both sides of the middle cross bar perpendicular to the side mounting plates; a vibration motor is provided on the top of the middle cross bar, and a direction adjustment mechanism is connected to the top output end of the vibration motor; two groups of shock-absorbing components are symmetrically provided at the bottom edges of both ends of the direction adjustment mechanism body, and the bottoms of the two groups of shock-absorbing components are respectively installed on the two groups of side cross bars.

[0014] Furthermore, the material shifting mechanism includes two groups of transverse rods, each of which is sleeved with a group of gears, and the two groups of gears are meshed with each other; a second motor is transmission-connected to the input end of one group of transverse rods.

[0015] Furthermore, a group of material-discharging rollers are provided on the output ends of the two groups of transverse rods, the height of the gap between the two groups of material-discharging rollers is the same as the height of the highest point of the material transporting plate, and a plurality of groups of material-discharging protrusions are evenly distributed on the surface of the material-discharging rollers.

[0018] The beneficial effects of the present invention are:

[0019] 1. The acupuncture needles are transported to the corresponding group of pressing plates at a uniform speed through the material transport tray, and the pressing plates are used to align the groups of acupuncture needles. Then the acupuncture needles pass through the corresponding group of high-speed rotating grinding heads in turn, and the upper and lower sides of the acupuncture needles are polished using the inner wall of the V-shaped ring groove. Then the acupuncture needles are moved to rotate by the material transfer mechanism, and then the unpolished parts of the acupuncture needles are polished using another group of grinding heads. Without manual operation, the batch automatic flipping and all-round batch polishing of acupuncture needles are realized. While ensuring the polishing quality, the automation effect of the device is also improved, the labor intensity is reduced, and the smoothness of the sharpening work is ensured.

[0020] 2. After the acupuncture needles are polished, they will come to the discharge box as the transport tray rotates, and the two ends of the acupuncture needles will slide into the two sets of discharge troughs respectively. Since the discharge trough is a fan-shaped structure and its curvature is greater than the curvature of the transport tray, the acupuncture needles will be detached from the needle body slots due to the large curvature of the discharge troughs when the transport tray continues to rotate, thus avoiding the problem of easy deformation of the acupuncture needles caused by brute force operation. When the acupuncture needles are completely detached from the needle body slots, they come to the bottom of the discharge trough and are transported to the discharge trough by the feed trough, thus realizing the function of automatic unloading in a continuous manner, without manual operation or stopping the device. While ensuring that the acupuncture needles are not deformed, the unloading work fluency is improved and the labor intensity is reduced.

[0021] 3. After the acupuncture needles pass through the wide feed opening and enter the through slot, they will slide and fit with the fourth slope, and gradually arrange neatly under the resistance of the fourth slope, ensuring that the sharpening degree of each group of acupuncture needles is the same, and the wide feed opening can also make a batch of acupuncture needles move horizontally and parallel. At the same time, the use of the top stabilizing plate also prevents the acupuncture needles from being separated from the needle body slot during grinding and turning over, thereby improving the stability of the sharpening work and reducing the defective rate of acupuncture needles.

[0022] 4. Put the batches of acupuncture needles into the adjustment box through the second feed port, and drive the adjustment box to vibrate through the vibration motor, so that the batches of acupuncture needles slide down along the third slope in sequence, and use vibration to adjust the horizontal sliding during the sliding process to achieve the adjustment work. And use the first product discharge seam, qualified product discharge seam and second product discharge seam to classify and place the defective products that are too short or too long and qualified products. While realizing the automatic adjustment of batches of acupuncture needles, different defective products can also be classified and removed, which not only improves the convenience of subsequent grinding, but also reduces the working time caused by manual removal of defective products.

[0023] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0040] The embodiment of the present invention provides a fully automatic handle sharpening device for flat-handled acupuncture needles, for example, Figure 1 As shown, it includes a vertical plate 100, on which a feeding unit 200 is installed. The feeding unit 200 is used to adjust the orientation of acupuncture needles in batches to improve the convenience of subsequent sharpening work.

[0041] The output end of the feeding unit 200 is provided with a material stopper unit 300, which is installed on the vertical plate 100 and is located on a side of the feeding unit 200 perpendicular to the vertical plate 100. The material stopper unit 300 is used to transport acupuncture needles in batches at a uniform speed and to stack the acupuncture needles neatly.

[0042] The side of the material-retaining unit 300 away from the vertical plate 100 is provided with a sharpening unit 400. The sharpening unit 400 is used to sharpen the acupuncture needles.

[0043] A discharging unit 500 is provided on one side of the material-receiving unit 300 away from the material-feeding unit 200. The discharging unit 500 is used to remove the acupuncture needles on the material-receiving unit 300 that have been sharpened.

[0044] For example, Figure 2 , Figure 3 and Figure 4 As shown, the feeding unit 200 includes a feeding box 210, and a first feeding port 211 is provided at the top edge of the side of the feeding box 210 away from the material-resisting unit 300, and a feeding box outlet 213 is provided at the bottom edge of the side of the feeding box 210 close to the material-resisting unit 300. The bottom inner wall of the feeding box 210 is provided with a first slope 212, and the height of the first slope 212 near one end of the first feeding port 211 is higher than the other end. The top inner wall of the feeding box outlet 213 is provided with a second slope 214, and the height of the second slope 214 near one side of the opening of the feeding box outlet 213 is lower than the other side.

[0045] Exemplarily, two groups of side mounting plates 220 are symmetrically arranged at the edges of both sides of the top of the first feed port 211, a middle crossbar 221 is arranged between the two groups of side mounting plates 220, and two groups of side crossbars 222 are arranged on both sides of the middle crossbar 221 perpendicular to the side mounting plates 220. A vibration motor is arranged at the top of the middle crossbar 221, and a direction adjustment mechanism 230 is connected to the top output end of the vibration motor. Two groups of shock absorbing components 223 are symmetrically arranged at the bottom edges of both ends of the main body of the direction adjustment mechanism 230, and the bottoms of the two groups of shock absorbing components 223 are respectively installed on the two groups of side crossbars 222.

[0046] Specifically, a clamping plate 260 is provided above the supply box outlet 213 .

[0047] For example, Figure 4 and Figure 5 As shown, the direction adjustment mechanism 230 includes a direction adjustment box 231, a second feed port 233 is provided at the top edge of one end of the direction adjustment box 231, and a third slope 232 is provided on the bottom inner wall of the direction adjustment box 231. The height of the third slope 232 near the second feed port 233 is higher than that of the other end. A qualified product discharge slit 234 is provided on the bottom inner wall of the third slope 232. A first product discharge slit 235 is provided on the side of the qualified product discharge slit 234 near the second feed port 233, and a second product discharge slit 236 is provided on the side of the qualified product discharge slit 234 away from the second feed port 233. The width of the qualified product discharge slit 234 is greater than the first product discharge slit 235, and less than the width of the second product discharge slit 236.

[0048] Exemplarily, a qualified product guide plate 240 is provided at the bottom of the qualified product discharge slit 234, a guide slit 241 is provided on the qualified product guide plate 240 in a vertical direction, and the bottom of the qualified product guide plate 240 extends into the cavity of the feed box 210 through the first feed inlet 211. The bottoms of the first product discharge slit 235 and the second product discharge slit 236 are both connected to a group of defective product boxes 250.

[0049] Preferably, the adjustment mechanism 230 also includes but is not limited to a third product cutting seam, a fourth product cutting seam and a fifth product cutting seam, and the widths of the three are different. The qualified product cutting seam 234, the first product cutting seam 235, the second product cutting seam 236, the third product cutting seam, the fourth product cutting seam and the fifth product cutting seam are arranged in order from small to large in width along the third slope 232 from high to low, and the qualified product cutting seam 234 with moderate width is placed in the middle position, so that defective products and qualified products of different lengths can fall into different gaps respectively, which is convenient for classification and rework at a later time.

[0050] First, a batch of acupuncture needles are placed into the adjustment box 231 through the second feed port 233, and then the vibration motor is turned on, and the vibration motor drives the adjustment box 231 to vibrate, so that the batch of acupuncture needles slide downward along the third slope 232 in sequence, and use vibration to adjust the horizontal sliding during the sliding process. When the acupuncture needles pass through the first product unloading slit 235, those defective products that are too short will fall through the first product unloading slit 235 to a corresponding group of defective boxes 250 below. Other acupuncture needles will continue to slide horizontally. When passing through the qualified product unloading slit 234, qualified products with moderate length will fall through the qualified product unloading slit 234 into the guide slit 241 below, and fall into the bottom feed box 210 through the guide slit 241. The overlong defective products will continue to slide and enter the corresponding group of defective boxes at the bottom from the second product unloading slit 236. Not only does the adjustment of the acupuncture needles work, but also the too short and too long acupuncture needles can be classified, which is convenient for later repair.

[0051] After qualified acupuncture needles enter the supply box 210, they will slide horizontally along the first slope 212 toward the supply box outlet 213, and then each group of acupuncture needles will be transported out in sequence through the material stop unit 300. In addition, the second slope 214 is used to prevent the batches of acupuncture needles from all rushing into the supply box outlet 213 at the same time, but passing through the supply box outlet 213 in sequence.

[0052] A batch of acupuncture needles are placed into the adjustment box 231 through the second feed port 233, and the adjustment box 231 is driven to vibrate by the vibration motor, so that the batch of acupuncture needles slide down along the third slope 232 in sequence, and the vibration is used to adjust the horizontal sliding during the sliding process to achieve the adjustment work. The first product discharge slit 235, the qualified product discharge slit 234 and the second product discharge slit 236 are used to classify and place the short and long defective products and qualified products. While realizing the automatic adjustment of the batch of acupuncture needles, different defective products can also be classified and removed, which not only improves the convenience of subsequent grinding, but also reduces the working time caused by manual removal of defective products.

[0053] At the same time, by using multiple sets of defective product cutting seams with different set widths, defective products of different lengths can be further classified, thereby improving the convenience of subsequent repair of defective products.

[0054] For example, Figure 6 , Figure 7 and Figure 8 As shown, the material-blocking unit 300 includes a first motor 310, the base of the first motor 310 is mounted on the vertical plate 100, and the output end of the first motor 310 is drivingly connected to a horizontally arranged first rotating rod 311, and the other end of the first rotating rod 311 is provided with a material transporting tray 320, and a plurality of groups of needle body clamping grooves 321 are distributed in a circular array on the side wall of the material transporting tray 320, and the side wall of the material transporting tray 320 is slidably fitted with the bottom of the clamping plate 260. The material transporting tray 320 is rotatably connected to a stabilizing shaft 330 on the side away from the first rotating rod 311, and the bottom of the stabilizing shaft 330 is fixedly connected to the vertical plate 100 through a connecting rod.

[0055] Exemplarily, the material transport tray 320 is provided with a material dispensing mechanism 340 on one side close to the vertical plate 100, and the height of the material dispensing mechanism 340 is the same as the height of the highest point of the material transport tray 320. Two sets of material pressing plates 350 are symmetrically provided on both sides of the material dispensing mechanism 340, and a through slot with both ends open is provided at the center of the material pressing plate 350, and a wide feeding opening 351 is provided at the port of one end of the through slot close to the feeding unit 200, and a fourth slope 352 is provided at the wide feeding opening 351, and the other end of the fourth slope 352 extends obliquely into the through slot. A material stabilizing plate 360 ​​with a fan-shaped ring structure is slidably fitted on the top of the material transport tray 320.

[0056] For example, Fig. 9 As shown, the material-dispensing mechanism 340 includes two groups of transverse rods, and a group of gears 342 are sleeved on the two groups of transverse rods, and the two groups of gears 342 are meshed with each other. A second motor 341 is connected to the input end of one group of transverse rods. A group of material-dispensing rollers 343 are provided on the output ends of the two groups of transverse rods, and the height of the gap between the two groups of material-dispensing rollers 343 is the same as the height of the highest point of the material transporting plate 320, and a plurality of groups of material-dispensing protrusions 344 are evenly distributed on the surface of the material-dispensing rollers 343.

[0057] For example, Fig.10 As shown, the sharpening unit 400 includes an electric slide 401, a slide bar 402 is slidably connected to the electric slide 401, a crescent plate 410 of a fan-shaped structure is provided on the top of the slide bar 402, two groups of abrasive boxes 420 are installed on the side wall of the crescent plate 410 close to the material transporting plate 320, the two groups of abrasive boxes 420 are parallel to the two groups of pressing plates 350, and the two side walls of the abrasive box 420 close to the material transporting plate 320 and perpendicular to the material transporting plate 320 are both open structures. A third motor 430 is provided on the top of the abrasive box 420, an abrasive mechanism 440 is provided in the abrasive box 420, and the input end of the abrasive mechanism 440 is drivingly connected to the third motor 430.

[0058] For example, Fig.11 As shown, the abrasive mechanism 440 includes a grinding head 441, a V-shaped ring groove 443 is opened at the center of the grinding head 441, the height of the V-shaped ring groove 443 is the same as the height of a corresponding group of pressure plates 350, and a second rotating rod 442 is connected to the grinding head 441, and the second rotating rod 442 is connected to the third motor 430 for transmission.

[0059] By turning on the first motor 310, the transport tray 320 is driven to rotate from the side of the feeding unit 200 to the side of the unloading unit 500. When one group of needle body slots 321 passes through the supply box outlet 213, the front group of acupuncture needles slide out of the supply box outlet 213 and fall into the group of needle body slots 321. As the transport tray 320 continues to rotate, it comes to the clamping plate 260, and through the sliding fit between the clamping plate 260 and the side wall of the transport tray 320, the acupuncture needles are moved and completely clamped in the group of needle body slots 321. Then it comes to a group of pressing plates 350 near the feeding unit 200, and then along the resistance of the fourth slope 352 in the through groove, each group of acupuncture needles can be arranged in a flush manner. Then, as the material transport plate 320 continues to rotate, each group of neatly arranged acupuncture needles passes through the grinding head 441 of the corresponding group of grinding mechanisms 440 in turn, and the upper and lower sides of the acupuncture needles are sharpened by the sliding fit between the acupuncture needles and the upper and lower side walls of the rotating V-shaped annular groove 443.

[0060] After the grinding mechanism 440 has completed the sharpening, the transport plate 320 continues to transport the acupuncture needle and separates it from the pressure plate 350, and at the same time comes between the two sets of feed rollers 343. Since the two sets of feed rollers 343 are connected by two sets of gears 342, the two sets of feed rollers 343 will rotate in opposite directions. When the acupuncture needle passes through the gap between the two sets of feed rollers 343, it will rotate through the fluctuations thereof, so that the two sides that have not been ground rotate up and down, and come to a set of pressure plates 350 away from the feeding unit 200, and the unground parts of the acupuncture needle are ground by a corresponding set of grinding heads 441 of the pressure plates 350, thereby realizing automatic flipping and batch grinding of the acupuncture needles.

[0061] The acupuncture needles are transported in batches at a uniform speed to a corresponding group of pressing plates 350 through the material transport tray 320, and the pressing plates 350 are used to align the groups of acupuncture needles. Then, the acupuncture needles pass through a corresponding group of high-speed rotating grinding heads 441 in turn, and the upper and lower sides of the acupuncture needles are polished using the inner wall of the V-shaped ring groove 443. Then, the acupuncture needles are moved by the material shifting mechanism 340 to rotate, and then another group of grinding heads are used to polish the unpolished parts of the acupuncture needles. Without manual operation, the batch automatic flipping and all-round batch polishing of acupuncture needles are realized. While ensuring the polishing quality, the automation effect of the device is also improved, the labor intensity is reduced, and the smoothness of the sharpening work is ensured.

[0062] After the acupuncture needles pass through the wide feeding opening 351 and enter the through slot, they will slide and fit with the fourth slope 352, and gradually arrange neatly under the resistance of the fourth slope 352, ensuring that the sharpening degree of each group of acupuncture needles is the same, and the batch of acupuncture needles can also move horizontally and parallelly through the wide feeding opening 351. At the same time, the top stabilizing plate 360 ​​also prevents the acupuncture needles from being separated from the needle body slot 321 during grinding and turning over, thereby improving the stability of the sharpening work and reducing the defective rate of acupuncture needles.

[0063] For example, Fig.12 and Fig.13 As shown, the unloading unit 500 includes a unloading box 510, which is located on the side of the transport tray 320 away from the feeding unit 200, and a discharge trough 540 is provided at the bottom edge of the wall of the side of the unloading box 510 away from the transport tray 320. The side of the unloading box 510 close to the transport tray 320 is an open structure, and two sets of fan-shaped unloading troughs 520 are symmetrically provided on the two side walls of the unloading box 510. The top of the unloading trough 520 is an open structure, and the height is the same as the center line of the transport tray 320 in the horizontal direction, and the curvature of the unloading trough 520 is greater than the curvature of the transport tray 320. The bottom of the unloading trough 520 is connected to the feeding trough 530, and the bottom of the feeding trough 530 extends obliquely toward the side of the discharge trough 540 and is connected to the discharge trough 540.

[0064] After the acupuncture needles are polished, the transport tray 320 rotates to the discharge box 510, and the two ends of the acupuncture needles slide into the two sets of discharge slots 520 respectively. Since the discharge slots 520 are fan-shaped structures and the curvature is greater than the curvature of the transport tray 320, the acupuncture needles will be separated from the needle body slots 321 due to the larger curvature of the discharge slots 520 when the transport tray 320 continues to rotate, thus avoiding the problem of easy deformation of the acupuncture needles caused by brute force operation. When the acupuncture needles are completely separated from the needle body slots, they come to the bottom of the discharge slots 520 and are transported to the discharge slots 540 by the feed slots 530, thereby realizing the function of automatic unloading in a continuous manner, without manual operation or stopping the device. On the premise of ensuring that the acupuncture needles are not deformed, the unloading work fluency is improved and the labor intensity is reduced.

[0065] The above embodiment also has the following beneficial effects:

[0066] 1. The acupuncture needles are transported in batches at a uniform speed to a corresponding group of pressing plates 350 through the material transport plate 320, and the pressing plates 350 are used to align each group of acupuncture needles. Then, the acupuncture needles pass through a corresponding group of high-speed rotating grinding heads 441 in turn, and the upper and lower sides of the acupuncture needles are polished using the inner wall of the V-shaped ring groove 443. Then, the acupuncture needles are moved by the material shifting mechanism 340 to rotate, and then another group of grinding heads are used to polish the unpolished parts of the acupuncture needles. Without manual operation, the automatic batch flipping and all-round batch polishing of acupuncture needles are realized. While ensuring the polishing quality, the automation effect of the device is also improved, the labor intensity is reduced, and the smoothness of the sharpening work is ensured.

[0067] 2. After the acupuncture needles are polished, the transport tray 320 rotates to the discharge box 510, and the two ends of the acupuncture needles slide into the two sets of discharge slots 520 respectively. Since the discharge slots 520 are fan-shaped structures and the curvature is greater than the curvature of the transport tray 320, the acupuncture needles will be separated from the needle body slots 321 due to the larger curvature of the discharge slots 520 when the transport tray 320 continues to rotate, thus avoiding the problem of easy deformation of the acupuncture needles caused by brute force operation. When the acupuncture needles are completely separated from the needle body slots, they come to the bottom of the discharge slots 520 and are transported to the discharge slots 540 by the feed slots 530, thereby realizing the function of automatic unloading in a continuous manner, without manual operation or stopping the device. On the premise of ensuring that the acupuncture needles are not deformed, the unloading work fluency is improved and the labor intensity is reduced.

[0068] 3. After the acupuncture needles pass through the wide feeding opening 351 and enter the through groove, they will slide and fit with the fourth slope 352, and gradually arrange neatly under the resistance of the fourth slope 352, ensuring that the sharpening degree of each group of acupuncture needles is the same, and the batch of acupuncture needles can also move horizontally and parallelly through the wide feeding opening 351. At the same time, the top stabilizing plate 360 ​​also prevents the acupuncture needles from being separated from the needle body slot 321 during grinding and turning over, thereby improving the stability of the sharpening work and reducing the defective rate of acupuncture needles.

[0069] 4. Put the batch of acupuncture needles into the adjustment box 231 through the second feed port 233, and drive the adjustment box 231 to vibrate through the vibration motor, so that the batch of acupuncture needles slide down along the third slope 232 in sequence, and use vibration to adjust the horizontal sliding during the sliding process to achieve the adjustment work. And use the first product discharge slit 235, the qualified product discharge slit 234 and the second product discharge slit 236 to classify and place the short and long defective products and qualified products. While realizing the automatic adjustment of the batch of acupuncture needles, different defective products can also be classified and removed, which not only improves the convenience of subsequent grinding, but also reduces the working time caused by manual removal of defective products.
