Description

Technical Field

[0001] The invention relates to the technical field of needle grinding machines, in particular to a needle grinding machine and a needle grinding method for punching holes in a spinneret. Background Art

[0002] In the textile industry, the spinneret is a key component used to extrude polymer melt into filaments. There are many fine holes on the spinneret, and the molten polymer is extruded through these holes to form fibers. The grinding needle is a very slender tool used to process or trim the holes on the spinneret. The grinding needle will wear out over a long period of time, affecting the punching of the spinneret, and needs to be polished regularly.

[0003] For example, the patent with the national authorized patent announcement number CN209095236U discloses a small needle grinding machine specially used for needle grinding, including a needle grinding device, a feed adjustment device and a swing mechanism. The feed adjustment device is arranged on one side of the needle grinding device, and the swing mechanism is arranged below the feed adjustment device. The device of the utility model adopts a feed adjustment device and a swing mechanism, especially a lifting mechanism and an angle adjustment mechanism in the feed adjustment device. The lifting mechanism and the angle adjustment mechanism cooperate to adjust the angle of the needle more accurately. At the same time, due to the manual adjustment of the upper and lower heights and angles, the structure is simple, easy to operate, and the maintenance cost is low. In addition, due to the use of a swing mechanism, the needle can wear the sanding belt more evenly during the grinding process, preventing the situation in which a certain position of the sanding belt is in excessive contact with the needle and is worn more heavily than other positions during the grinding process, thereby extending the service life of the sanding belt and reducing the cost of consumables when grinding needles.

[0004] However, the above-mentioned small-scale dedicated needle grinding machine cannot automatically fill the grinding needles during the grinding process to realize the needle grinding processing operation without stopping the machine, and manual loading and unloading are required, which will lead to interruption of the needle grinding process and reduce work efficiency. Especially in mass production, it will increase the workload and downtime of the operator, and it is also unable to adjust the needle tip amplitude that needs to be ground, that is, the grinding angle, according to the processing needs, resulting in low operational flexibility and inability to process different types of needle tips.

[0056] Through the design of the third motor 302, the connecting plate 303, the guide groove 304, the hand wheel 305, the guide block 306, the grinding needle disc 307, the first threaded rod 308 and the second threaded rod 309, when grinding the grinding needle, the first threaded rod 308 can be driven to rotate in the guide groove 304 by twisting the hand wheel 305, so that the first threaded rod 308 can drive the guide block 306 to slide horizontally in the guide groove 304, and the distance between the grinding needle disc 307 at one end of the guide block 306 and the grinding needle can be adjusted, and the distance between the grinding needle disc 307 and the grinding needle can be fine-tuned to adapt to grinding needles of different thicknesses. The accuracy during the grinding process is ensured so that it can be adjusted appropriately according to the thickness of the grinding needle. Subsequently, the outer surface of the second threaded rod 309 can be transmitted by twisting the rotating drum 311, so that the transmission 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 inclination. Different inclination angles mean that the grinding needle disk 307 can grind the grinding needle into needle tips of different amplitudes. This design allows the needle grinder 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 needle grinding processing requirements of different types and specifications.

[0057] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when grinding the grinding needles, the needle collection cylinder 203 containing the grinding needles can be slidably inserted on the upper surface of the guide plate 202, so that the needle collection cylinder 203 is flush with and connected to the feed pipe opening 213, and then the second motor 211 can be started to drive the feed disc 208 to rotate in the connecting cylinder 201. During the rotation of the feed disc 208 in the connecting cylinder 201, the storage groove 209 opened on the outer surface of the feed disc 208 is flush with and connected to the feed pipe opening 213, so that the grinding needles in the needle collection cylinder 203 can fall into the storage groove 209 through the feed pipe opening 213, and then the needle collection cylinder 203 can be filled with the grinding needles through the multiple groups of storage grooves 209 as the feed disc 208 continues to rotate. The grinding pins in 03 are all stored in the storage slot 209, until the feeding disk 208 drives the storage slot 209 with the grinding pins to rotate to be flush with the ejection port 212, and then the rotation can be stopped, and then the first electric push rod 205 can be started to pull the U-shaped connecting arm 210 at one end of the piston rod to insert into the ejection port 212, so that the grinding pin can be pushed out of the storage slot 209, and the pushed grinding pin can be placed in the placement slot 207 on the upper surface of the first electric push rod 205, and then the second electric push rod 204 can be started to push the clamping plate 206 fixedly installed on the lower surface of the piston rod to press on the upper end of the outer surface of the grinding pin, so that the grinding pin can be clamped between the clamping plate 206 and the placement slot 207, and then the first threaded rod 308 can be driven by twisting the hand wheel 305. By rotating in the guide groove 304, the first threaded rod 308 can drive the guide block 306 to slide horizontally in the guide groove 304, and the distance between the grinding needle disk 307 at one end of the guide block 306 and the grinding needle can be adjusted. The distance between the grinding needle disk 307 and the grinding needle can be fine-tuned to adapt to grinding needles of different coarsenesses and ensure the accuracy of the grinding process. After the distance between the grinding needles is adjusted, the outer surface of the second threaded rod 309 can be twisted to transmit the rotating drum 311, and the transmission of the rotating drum 311 on the outer surface of the second threaded rod 309 can achieve pushing or pulling the grinding needle disk 307 to adjust the inclination. Different inclination angles mean that the grinding needle disk 307 can grind the grinding needle into needles of different amplitudes. After adjusting the inclination of the grinding needle disk 307, the linear module 103 and the third motor 302 can be started at the same time, and the linear module 103 can drive the grinding needle clamped at one end of the connecting tube 201 to approach the grinding needle disk 307, and the third motor 302 can drive the adjusted grinding needle disk 307 to rotate to grind the approaching grinding needle, and after grinding is completed, 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, and 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 slot 209 and make it fall on the upper surface of the conveyor belt 102 to be transported away,Then the second motor 211 can be started again to drive the grinding pin in the storage slot 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 be pushed out again and clamped for grinding operation.

[0058] In summary: the needle grinding machine achieves a continuous supply of grinding needles through the rotation of the feed disk 208 and the use of the storage tank 209, avoids manual intervention, greatly improves the production speed, and can also adjust the shape and angle of the needle tip by adjusting the inclination of the grinding needle disk 307, making the equipment more flexible and suitable for handling different types and specifications of grinding needle processing needs.
