Description

Technical Field

[0001] This utility model relates to the field of grinding needle technology, specifically a grinding needle machine for grinding needles used in spinneret punching. Background Technology

[0002] In the textile industry, the spinneret is a key component used to extrude polymer melt into fine filaments. The spinneret has many fine holes through which molten polymer is extruded to form fibers. Grinding needles are very thin and long tools used to process or trim these holes in the spinneret. However, prolonged wear on the grinding needles can cause wear and affect the perforation of the spinneret, necessitating periodic grinding of the grinding needles.

[0003] For example, the patent with authorized patent announcement number CN209095236U discloses a small needle grinding machine, including a needle grinding device, a feed adjustment device, and a swing mechanism. The feed adjustment device is located on one side of the needle grinding device, and the swing mechanism is located below the feed adjustment device. The device of this utility model adopts a feed adjustment device and a swing mechanism, especially the lifting mechanism and angle adjustment mechanism in the feed adjustment device. The lifting mechanism and angle adjustment mechanism work together to adjust the angle of the needle more precisely. At the same time, because it adopts a manual adjustment method for the height and angle, the structure is simple, easy to operate, and has low maintenance costs. Furthermore, because of the use of the swing mechanism, the wear of the abrasive belt on the needle is more uniform during the grinding process, preventing the abrasive belt from wearing more wear in one place than in other places during the grinding process, thus extending the service life of the abrasive belt and reducing the consumable costs during needle grinding.

[0004] However, the aforementioned small-scale needle grinding machine cannot automatically load and unload needles during the grinding process to achieve non-stop grinding operations. Manual loading and unloading is required, which leads to interruptions in the grinding process and reduces work efficiency. Especially in mass production, this increases the workload of operators and downtime. Furthermore, it cannot adjust the needle tip radius, i.e., the grinding angle, according to processing needs, resulting in low operational flexibility and the inability to process different types of needle tips. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding machine for grinding needles used in spinneret punching, so as to solve the problems mentioned in the background art, that the grinding needles cannot be automatically filled to achieve grinding needle processing operation without stopping the machine, and that the needle tip amplitude, i.e. grinding angle, to be ground can not be adjusted according to processing needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Both the grinding mechanism and the feeding and pushing mechanism are located directly above the conveyor belt.

[0009] The feeding and pushing mechanism can drive the grinding needle to contact the grinding end of the grinding mechanism through the linear module.

[0010] Preferably, the feeding and pushing mechanism includes a connecting cylinder, which is fixedly installed between the moving blocks of two sets of linear modules.

The needle collecting cylinder can slide to be connected to the feed inlet, so that the grinding needles in the needle collecting cylinder can fall into the storage tank through the feed inlet.

[0012] Preferably, the storage tank can be rotated by the feeding disc to be flush with the ejector port. The ejector port is located at both ends of the connecting cylinder and is flush with the ejector port. Rotating the storage tank to be flush with the ejector port can drive the grinding needle to be flush with the ejector port.

[0013] Preferably, a first electric push rod is fixedly installed on the lower surface of the connecting cylinder.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Through the design of a stabilizing plate, connecting frame, conveyor belt, linear module, feeding and pushing mechanism, and grinding mechanism, the grinding needles are ground by loading the grinding needles into the feeding and pushing mechanism. The feeding and pushing mechanism separates the grinding needles into groups and pushes them out for clamping. Then, by activating the linear module, the feeding and pushing mechanism moves towards the grinding mechanism, allowing the feeding and pushing mechanism to move the clamped grinding needles into the grinding mechanism for grinding the needle tips. After grinding, the grinding needles are pushed out of the feeding and pushing mechanism, falling onto the surface of the conveyor belt and being transported to another processing step. Another set of grinding needles inside the structure is automatically pushed out and clamped, realizing the functions of automatic feeding and unloading. It eliminates the need for manual operation, greatly improves work efficiency, and reduces the frequency of manual intervention. Especially in mass production, this automated design can significantly shorten processing time and improve the continuity of the production line. During the grinding process, the grinding mechanism can adjust the position and inclination of the grinding surface, allowing the operator to adjust the inclination of the grinding mechanism according to the processing needs. This changes the amplitude of the grinding needle tip, i.e., the grinding angle, so that the equipment can adapt to the processing needs of different types and specifications of grinding needles, increasing the applicability of the equipment.

[0021] 2. The design incorporates a feeding tray, storage tank, second electric push rod, clamping plate, first electric push rod, U-shaped connecting arm, and second motor. During use, the needle collection cylinder containing grinding needles is slid into the upper surface of the guide plate, aligning it with the feed inlet. The second motor then rotates the feeding tray within the connecting cylinder. This rotation aligns the storage tank on the outer surface of the feeding tray with the feed inlet, allowing the grinding needles in the collection cylinder to fall into the storage tank through the feed inlet. As the feeding tray continues to rotate, multiple storage tanks store the grinding needles from the collection cylinder until the storage tank with the grinding needles is aligned with the ejection port. Rotation is then stopped, and the first electric push rod pulls the U-shaped connecting arm at one end of the piston rod into the ejection port, ejecting the grinding needles from the storage tank. The ejected grinding needles are positioned in the placement slot on the upper surface of the first electric push rod. The second motor then... Two electric push rods push the clamping plate fixedly installed on the lower surface of the piston rod, pressing it against the upper part of the outer surface of the grinding needle. This clamps the grinding needle between the clamping plate and the placement slot. Then, by activating the linear module, the grinding needle clamped at one end of the connecting cylinder moves closer to the grinding mechanism for grinding. After grinding, the first and second electric push rods can be activated again. The second electric push rod lifts the clamping plate to release the grinding needle, while the first electric push rod pulls the U-shaped connecting arm through the piston rod to push the grinding needle completely out of the storage slot and drop it onto the upper surface of the conveyor belt for transport. Then, the second motor can be activated again to align the grinding needle in the storage slot of the feeding tray with the ejection port, allowing the U-shaped connecting arm of the first electric push rod to eject and clamp it again. Through the rotation of the feeding tray and the use of the storage slot, a continuous supply of grinding needles is achieved, avoiding manual intervention and significantly improving production speed. The entire process, from picking up, transferring, and positioning the grinding needle to grinding and ejection, is completed automatically, reducing manual operation and error rate.

[0022] 3. Through the design of the third motor, connecting plate, guide groove, handwheel, guide block, grinding needle disc, first threaded rod, and second threaded rod, the grinding needle can be ground by rotating the handwheel to drive the first threaded rod to rotate in the guide groove. This allows the first threaded rod to drive the guide block to slide horizontally in the guide groove, adjusting the distance between the grinding needle disc and the grinding needle at one end of the guide block. This allows for fine-tuning of the distance between the grinding needle disc and the grinding needle, accommodating grinding needles of different thicknesses and ensuring accuracy during the grinding process. The grinding needle disc can be adjusted according to the thickness of the grinding needle. Subsequently, the rotating drum can be driven on the outer surface of the second threaded rod, pushing or pulling the grinding needle disc to adjust its tilt. Different tilt angles mean that the grinding needle disc can grind the grinding needle into needle tips of different widths. This design allows the grinding needle machine to flexibly adjust the shape and angle of the needle tip according to different processing needs, making the equipment more flexible and suitable for processing different types and specifications of grinding needles.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-10 This embodiment provides the following technical solution:

[0036] like Figures 1-4 As shown, a grinding machine for grinding needles for punching holes in spinnerets includes: a stabilizing plate 1, two sets of connecting plates 108 fixedly installed on the upper surface of the stabilizing plate 1, two sets of transmission columns 109 being driven between the two sets of connecting plates 108, and a conveyor belt 102 fitted on the outer surface of the two sets of transmission columns 109. One end of one set of transmission columns 109 rotatably passes through the connecting plate 108 and a first transmission wheel 106 is fixedly installed at the end. A transmission belt 107 is fitted on the outer surface of the first transmission wheel 106, and the other end of the transmission belt 107 is fitted on the outer surface of the second transmission wheel 105. The second transmission wheel 105 is fixedly installed at one end of the output shaft of the first motor 104, and the first motor 104 is fixedly installed on the upper surface of the stabilizing plate 1.

[0037] Among them, a connecting frame 101 is fixedly installed on the upper surface of the stabilizing plate 1, two sets of linear modules 103 are fixedly installed on the upper surface of the connecting frame 101, a feeding and pushing mechanism 2 is fixedly installed between the moving blocks of the two sets of linear modules 103, and a grinding mechanism 3 for punching grinding needles of spinneret plate is fixedly installed on the lower surface of the connecting frame 101. The grinding end of the grinding mechanism 3 is flush with the feeding end of the feeding and pushing mechanism 2. Both the grinding mechanism 3 and the feeding and pushing mechanism 2 are located directly above the conveyor belt 102.

[0038] Among them, the feeding and pushing mechanism 2 can drive the grinding needle to contact the grinding end of the grinding mechanism 3 through the linear module 103.

[0039] Through the design of the stabilizing plate 1, connecting frame 101, conveyor belt 102, linear module 103, feeding and pushing mechanism 2, and grinding mechanism 3, when grinding the grinding needles, the grinding needles to be ground can be loaded into the feeding and pushing mechanism 2. The feeding and pushing mechanism 2 can separate the grinding needles in groups and push them out to clamp them. Then, by activating the linear module 103, the feeding and pushing mechanism 2 can be moved towards the grinding mechanism 3, allowing the feeding and pushing mechanism 2 to move the clamped grinding needles into the grinding mechanism 3 to grind the needle tips. After grinding, the grinding needles can be pushed out from the feeding and pushing mechanism 2, causing them to fall onto the surface of the conveyor belt 102 and be transported to another step of processing. In the process of grinding, another set of grinding needles in the feeding and pushing mechanism 2 is automatically pushed out and clamped, realizing the functions of automatic feeding and unloading. It eliminates the need for manual operation, greatly improves work efficiency, and reduces the frequency of manual intervention. Especially in mass production, this automated design can significantly shorten processing time and improve the continuity of the production line. In addition, during the grinding of the grinding needles, the grinding mechanism 3 can adjust the position and inclination of the grinding surface. The operator can adjust the inclination of the grinding mechanism 3 according to the processing needs, thereby changing the amplitude of the grinding needle tip, i.e., the grinding angle. This allows the equipment to adapt to the processing needs of different types and specifications of grinding needles, increasing the applicability of the equipment.

[0040] like Figures 5-8 As shown, the feeding and pushing mechanism 2 includes a connecting cylinder 201, which is fixedly installed between the moving blocks of the two linear modules 103. A feeding disc 208 is rotatably installed inside the connecting cylinder 201. A second motor 211 is fixedly installed at one end of the connecting cylinder 201. The output shaft of the second motor 211 passes through the connecting cylinder 201 and is fixedly installed at one end of the feeding disc 208. Multiple storage slots 209 are formed on the outer surface of the feeding disc 208. Grinding needles can be stored in the storage slots 209. By rotating the feeding disc 208, the connecting cylinder 201 can block the storage slots 209, so that the feeding disc 208 can keep the grinding needles in the storage slots 209 stable and rotate along with it during the rotation.

[0041] The storage tank 209 can be rotated to be flush with and connected to the feed inlet 213. The feed inlet 213 is connected to the upper end of the outer surface of the connecting cylinder 201. A guide plate 202 is fixedly installed at one end of the feed inlet 213. A needle collecting cylinder 203 is slidably installed in the guide plate 202. The needle collecting cylinder 203 can slide to be connected to the feed inlet 213, so that the grinding needles in the needle collecting cylinder 203 can fall into the storage tank 209 through the feed inlet 213.

[0042] The storage tank 209 can be rotated by the feeding plate 208 to be flush with the ejector port 212. The ejector port 212 is opened at both ends of the connecting cylinder 201 and is flush with it. Rotating the storage tank 209 to be flush with the ejector port 212 can drive the grinding needle to be flush with the ejector port 212.

[0043] A first electric push rod 205 is fixedly installed on the lower surface of the connecting cylinder 201. A U-shaped connecting arm 210 is fixedly installed on one end of the piston rod of the first electric push rod 205. The U-shaped connecting arm 210 can be pulled and slid into the push-out port 212, so as to push out the grinding needle stored in the storage groove 209 and push it out from the push-out port 212 at the other end.

[0044] The ejected grinding needle will slide into the placement groove 207, which is opened on the upper surface of the first electric push rod 205. The grinding needle located in the placement groove 207 can be clamped between the clamping plate 206 and the placement groove 207. The clamping plate 206 is fixedly installed at one end of the piston rod of the second electric push rod 204, and the second electric push rod 204 is fixedly installed at one end of the connecting cylinder 201.

[0045] Through the design of the feeding tray 208, storage groove 209, second electric push rod 204, clamping plate 206, first electric push rod 205, U-shaped connecting arm 210, and second motor 211, during use, the needle collecting cylinder 203 containing the grinding needles can be slid into the upper surface of the guide plate 202, so that the needle collecting cylinder 203 is flush with and connected to the feed inlet 213. Then, the second motor 211 can be started to drive the feeding tray 208 to rotate inside the connecting cylinder 201. During the rotation of the feeding tray 208 inside the connecting cylinder 201, the storage groove 209 on the outer surface of the feeding tray 208 will be flush with and connected to the feed inlet 213. The feeding disc 208 allows the grinding needles in the collecting cylinder 203 to fall into the storage tank 209 through the feed port 213. As the feeding disc 208 continues to rotate, multiple storage tanks 209 store all the grinding needles from the collecting cylinder 203. Rotation continues until the feeding disc 208 rotates the storage tanks 209 containing the grinding needles until they are flush with the ejection port 212. Rotation can then be stopped, and the first electric push rod 205 can be activated to pull the U-shaped connecting arm 210 at one end of the piston rod into the ejection port 212, thus ejecting the grinding needles from the storage tank 209. The ejected grinding needles are positioned on the upper surface of the first electric push rod 205. The grinding needle is placed in the placement groove 207. Then, by activating the second electric push rod 204, the clamping plate 206, which is fixedly installed on the lower surface of the piston rod, is pushed to press against the upper end of the outer surface of the grinding needle, thus clamping the grinding needle between the clamping plate 206 and the placement groove 207. Then, by activating the linear module 103, the grinding needle clamped at one end of the connecting cylinder 201 is driven to move closer to the grinding mechanism 3 for grinding. After grinding is completed, the first electric push rod 205 and the second electric push rod 204 can be activated again. The second electric push rod 204 can lift the clamping plate 206 to release the clamping of the grinding needle, while the first electric push rod 205 will pull the U-shaped connecting arm 21 through the piston rod. The grinding needle is completely pushed out of the storage tank 209 and falls onto the upper surface of the conveyor belt 102 for transport. Then, the second motor 211 can be restarted to drive the grinding needle in the storage tank 209 of the feeding tray 208 to be flush with the ejection port 212, so that the U-shaped connecting arm 210 of the first electric push rod 205 can push it out again and clamp it. Through the rotation of the feeding tray 208 and the use of the storage tank 209, the grinding needle is continuously supplied, avoiding manual intervention and greatly improving the production speed. Moreover, the entire process, from the picking, transmission, and positioning of the grinding needle to grinding and ejection, is completed automatically, reducing manual operation and lowering the error rate.

[0046] like Figures 9-10As shown, the grinding mechanism 3 includes a mounting plate 301. A third motor 302 is fixedly mounted inside the mounting plate 301. The third motor 302 is fixedly mounted on the lower surface of the connecting frame 101 through the mounting plate 301. A connecting plate 303 is fixedly mounted on one end of the third motor 302. A guide groove 304 is opened on one end of the connecting plate 303. A guide block 306 is slidably mounted inside the guide groove 304. A grinding needle disk 307 is rotatably mounted on one end of the guide block 306. The grinding needle disk 307 can be rotated by the third motor 302 to grind the grinding needle.

[0047] A first threaded rod 308 is installed in the guide groove 304 with damping. The threaded rod 308 passes through the guide block 306 and the rotation of the first threaded rod 308 can drive the guide block 306 to slide horizontally in the guide groove 304.

[0048] One end of the first threaded rod 308 extends from the guide groove 304 to the outer surface of the connecting plate 303, and a handwheel 305 is fixedly installed on one end of the first threaded rod 308 located on the surface of the connecting plate 303.

[0049] The other end of the grinding needle disk 307 is rotatably mounted with a first connecting rod 310. One end of the outer surface of the first connecting rod 310 is damped and rotatably mounted with a rotating drum 311. The rotating drum 311 is rotatably mounted on the outer surface of the second threaded rod 309. The second threaded rod 309 is fixedly mounted on one end of the second connecting rod 312. The second connecting rod 312 is rotatably mounted on the end of the guide block 306.

[0050] Through the design of the third motor 302, connecting plate 303, guide groove 304, handwheel 305, guide block 306, grinding needle disc 307, first threaded rod 308, and second threaded rod 309, when grinding the grinding needle, the first threaded rod 308 can be rotated within the guide groove 304 by turning the handwheel 305. This allows the first threaded rod 308 to drive the guide block 306 to slide horizontally within the guide groove 304. The distance between the grinding needle disc 307 and the grinding needle at one end of the guide block 306 can be adjusted, allowing for fine-tuning of the distance between the grinding needle disc 307 and the grinding needle, thus accommodating grinding needles of different grits. To ensure precision during the grinding process, the grinding needle can be adjusted according to the coarseness of the grinding needle. Subsequently, the rotating drum 311 can be driven on the outer surface of the second threaded rod 309. The rotation of the rotating drum 311 on the outer surface of the second threaded rod 309 can push or pull the grinding needle disk 307 to adjust the tilt angle. Different tilt angles mean that the grinding needle disk 307 can grind the grinding needle into needle tips of different widths. This design allows the grinding needle machine to flexibly adjust the shape and angle of the needle tip according to different processing requirements, making the equipment more flexible and suitable for processing different types and specifications of grinding needles.

[0051] Based on the above technical solution, the working steps of this solution are summarized as follows: When grinding the grinding needles, the needle collecting cylinder 203 containing the grinding needles can be slidably inserted into the upper surface of the guide plate 202, so that the needle collecting cylinder 203 is flush with and connected to the feed inlet 213. Then, the second motor 211 can be started to drive the feed tray 208 to rotate inside the connecting cylinder 201. During the rotation of the feed tray 208 inside the connecting cylinder 201, the storage groove 209 opened on the outer surface of the feed tray 208 will be flush with and connected to the feed inlet 213, allowing the grinding needles in the needle collecting cylinder 203 to fall into the storage groove 209 through the feed inlet 213. Subsequently, as the feed tray 208 continues to rotate, the needle collecting cylinder 203 can be filled with grinding needles through multiple sets of storage grooves 209. All grinding needles in compartment 03 are stored in storage slot 209. Rotation is stopped once the storage slot 209, containing the grinding needles, is rotated by the feed tray 208 until it is flush with the ejection port 212. Then, the first electric push rod 205 is activated to pull the U-shaped connecting arm 210 at one end of the piston rod into the ejection port 212, ejecting the grinding needles from the storage slot 209. The ejected grinding needles are positioned in the placement slot 207 on the upper surface of the first electric push rod 205. Next, the second electric push rod 204 is activated to push the clamping plate 206, fixedly mounted on the lower surface of the piston rod, against the upper end of the outer surface of the grinding needle, clamping the grinding needles between the clamping plate 206 and the placement slot 207. Finally, the first threaded rod 308 is driven by turning the handwheel 305. Rotating within the guide groove 304 allows the first threaded rod 308 to slide horizontally within the guide groove 304, adjusting the distance between the grinding needle disk 307 at one end of the guide block 306 and the grinding needle. This allows for fine-tuning of the distance between the grinding needle disk 307 and the grinding needle, accommodating grinding needles of different grits and ensuring precision during grinding. After the distance between the grinding needle and the grinding needle is adjusted, the rotating cylinder 311 can be twisted to drive the grinding needle disk 307 on the outer surface of the second threaded rod 309. This allows the rotating cylinder 311 to drive the grinding needle disk 307 to adjust its tilt angle by pushing or pulling it. Different tilt angles mean that the grinding needle disk 307 can grind the grinding needle into different diameters. After adjusting the inclination of the grinding needle disk 307, the linear module 103 and the third motor 302 can be started simultaneously. The linear module 103 can drive the grinding needle clamped at one end of the connecting cylinder 201 to move closer to the grinding needle disk 307. The third motor 302 can drive the adjusted grinding needle disk 307 to rotate and grind the approaching grinding needle. After grinding, the first electric push rod 205 and the second electric push rod 204 can be started again. The second electric push rod 204 can lift the clamping plate 206 to release the clamping of the grinding needle. The first electric push rod 205 will pull the U-shaped connecting arm 210 through the piston rod to push the grinding needle completely out of the storage tank 209 and let it fall onto the upper surface of the conveyor belt 102 and be conveyed away.Then, the second motor 211 can be restarted to align the grinding needles in the storage slot 209 of the feeding tray 208 with the ejection port 212, allowing the U-shaped connecting arm 210 of the first electric push rod 205 to be ejected again and clamped for grinding.

[0052] In summary, this needle grinding machine achieves continuous supply of grinding needles through the rotation of the feeding disc 208 and the use of the storage tank 209, avoiding manual intervention and significantly improving production speed. Furthermore, the shape and angle of the needle tip can be adjusted by adjusting the tilt of the grinding disc 307, making the equipment more flexible and suitable for processing different types and specifications of grinding needles.
