Description

Technical Field

[0001] This invention relates to the field of needle processing technology, and more specifically to a nonwoven fabric needle processing device. Background Technology

[0002] Nonwoven needles are core consumables in the production of nonwoven fabrics using the needle-punching method. Their structure, arrangement, and motion parameters directly determine the fiber entanglement effect and the quality of the finished product.

[0003] In the processing of nonwoven fabric needles, processes such as stamping and bending are generally involved. Stamping mainly involves stamping the needle head to create the needle shape, while bending involves bending the needle tail to facilitate installation during use. The entire processing is simple and straightforward, and therefore it is widely used.

[0004] However, currently, the stamping and bending of needles are carried out sequentially, that is, through multiple machines in sequence. This requires multiple loading, unloading and transfer processes, resulting in low overall processing efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a non-woven fabric needle processing device to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a nonwoven fabric needle processing equipment, comprising: a worktable for supporting components; a conveying assembly installed on the worktable and conveying needle blanks; a stamping assembly located above the conveying assembly and fixed to the worktable, which simultaneously stamps the head of the needle blank on the conveying assembly to form a needle shape; and a bending assembly installed on the worktable, which, when the stamping assembly stamps the needle blank, drives the bending assembly to bend the tail of the needle blank.

[0007] Furthermore, the bending direction of the bending assembly on the needle blank is opposite to the stamping direction of the stamping assembly.

[0008] Furthermore, the conveying assembly includes a conveying screw, a limiting rod, and a fixed seat. The conveying screw is rotatably mounted on the worktable and located below the stamping assembly. There are two conveying screws arranged in a flat manner. The two conveying screws rotate synchronously through a transmission assembly. The needle blank can be placed in the corresponding screw grooves of the two conveying screws. The rotation of the two conveying screws will drive the needle blank to move. The fixed seat is fixedly mounted on the worktable. The limiting rod is located above the conveying screw and is fixed to the fixed seat with bolts. At the same time, the limiting rod presses against the needle blank and keeps the needle blank in contact with the conveying screw.

[0009] Furthermore, the transmission assembly includes a transmission gear and a reversing gear. A mounting base is installed on the worktable. The lead screw is rotatably mounted on the mounting base. There are two transmission gears, which are fixedly mounted on the ends of the two lead screws respectively. The reversing gear is rotatably mounted on the side of the mounting base and meshes with the two transmission gears simultaneously.

[0010] Furthermore, the conveying assembly also includes a motor, the output of which provides torque to a conveying screw shaft via a chain and sprocket.

[0011] Furthermore, the stamping assembly includes a frame, a stamping head, and a drive component. The frame is fixedly connected to the worktable. The stamping head is positioned above the lead screw and is slidably mounted on the frame. The die can be mounted on the side of the stamping head near the conveying assembly. The drive component is mounted on the frame and drives the stamping head to slide.

[0012] Furthermore, the drive components include a crankshaft, connecting rod, and flywheel. The crankshaft is rotatably mounted on the frame. One end of the connecting rod is rotatably sleeved on the crankshaft, and the other end is rotatably connected to the stamping head. The rotation of the crankshaft will drive the stamping head to slide through the connecting rod. The flywheel is fixedly mounted on the crankshaft shaft. At the same time, the crankshaft and the motor output end are driven by a chain and sprocket.

[0013] Furthermore, the stamping assembly also includes a fixed rod, a guide block, a compression spring, and a limiting block. The guide block is fixedly installed on the stamping head and its position corresponds to the blank of the needle to be stamped. The fixed rod is slidably installed on the guide block. The limiting block is fixedly installed on the stamping head. The compression spring is located between the fixed rod and the limiting rod. At the same time, the bottom end of the fixed rod is lower than the bottom surface of the mold of the stamping head under the action of the compression spring, so that when the stamping head slides down, the fixed rod first presses the blank of the needle to be stamped. The bottom end of the fixed rod is provided with a groove. The groove is V-shaped and the narrow end is far away from the bottom end of the fixed rod.

[0014] Furthermore, the bending assembly includes a bending rod, a guide seat, and a linkage assembly. The guide seat is fixedly installed on the worktable, and the bending rod is slidably installed on the guide seat. The top end of the bending rod corresponds to the tail end of the needle blank to be processed. The linkage assembly is connected between the bending rod and the punch head. When the punch head slides down, it drives the linkage assembly to rotate, thereby causing the bending rod to slide up to bend the tail end of the needle blank.

[0015] Furthermore, the linkage assembly includes a power rod, a transmission plate, and a return spring. The power rod is slidably installed in the middle of the worktable and below the punch head. Simultaneously, the downward movement of the punch head can drive the power rod downward. The transmission plate is rotatably installed below the worktable, with one end of the transmission plate below the power rod and the other end below the bending rod. The downward movement of one end of the power rod drives the transmission plate to rotate, which in turn pushes the power rod upward. The return spring is installed between the bending rod and the worktable. Under the action of the return spring, the bending rod contacts the transmission plate and causes the transmission plate to rotate, thereby driving the power rod to rise above the worktable surface.

[0016] The technical effects and advantages of this invention are as follows: This invention allows for continuous or even simultaneous stamping and bending of the needles on a single machine, saving significant time on loading, unloading, and transfer, thus effectively improving production efficiency. Furthermore, because the bending direction of the needle blank by the bending assembly is opposite to the stamping direction of the stamping assembly, the two ends of the needle blank will be subjected to forces in two different directions during processing. Compared to forces in a single direction, the bending caused by forces in two different directions partially cancels each other out, resulting in a straighter needle blank after processing. This effectively reduces the difficulty of subsequent straightening. Finally, during the stamping process, the needle blank in the front-end material box is automatically loosened to ensure stable feeding of the needles, further guaranteeing processing efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative and are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-5 This invention provides a nonwoven fabric needle processing device, comprising: a worktable 1, a conveying assembly 2, a stamping assembly 3, and a bending assembly 4. The worktable 1 is used to support components; the conveying assembly 2 is installed on the worktable 1 and conveys needle blanks through the conveying assembly 2; the stamping assembly 3 is located above the conveying assembly 2 and is fixed to the worktable 1, and simultaneously stamps the head of the needle blank on the conveying assembly 2 to form a needle shape; the bending assembly 4 is installed on the worktable 1, and when the stamping assembly 3 stamps the needle blank, it drives the bending assembly 4 to bend the tail of the needle blank.

[0021] In this way, when using the equipment, the upper die of the mold to be used is fixed to the stamping assembly 3, and the lower die is installed on the worktable 1 and aligned with the upper die. Then, the needle blank to be processed is placed on the conveying assembly 2, which will transport the needle blank to the bottom of the stamping assembly 3. At this time, the stamping assembly 3 is started, which will stamp the needle blank above the conveying assembly 2 to process the needle shape. At the same time, when the stamping assembly 3 is running, it will also drive the bending assembly 4 to run synchronously to bend the tail of the needle blank. In this way, the stamping and bending processes can be performed simultaneously on one machine, effectively eliminating the intermediate loading and unloading and transfer processes, and greatly improving efficiency.

[0022] Further optimization is made based on the above scheme. Specifically, the bending direction of the bending component 4 is opposite to the stamping direction of the stamping component 3. In this way, when the needle blank is processed, the two ends of the needle blank will be subjected to two forces in different directions. Compared with the force in a single direction, the bending caused by the two forces in different directions will cancel each other out, thereby making the processed needle blank straighter and effectively reducing the difficulty of subsequent straightening.

[0023] In the above scheme, the conveying assembly 2 includes a conveying screw 201, a limiting rod 202, and a fixed seat 203. The conveying screw 201 is rotatably mounted on the worktable 1 and located below the stamping assembly 3. There are two conveying screws 201 arranged in a flat manner. The two conveying screws 201 rotate synchronously through the transmission assembly 5. The needle blank can be placed in the corresponding screw grooves of the two conveying screws 201. At the same time, the rotation of the two conveying screws 201 will drive the needle blank to move. The fixed seat 203 is fixedly mounted on the worktable 1. The limiting rod 202 is located above the conveying screw 201 and is fixed to the fixed seat 203 by bolts. At the same time, the limiting rod 202 presses against the needle blank and keeps the needle blank in contact with the conveying screw 201.

[0024] The transmission assembly 5 includes a transmission gear 501 and a reversing gear 502. A mounting base 204 is installed on the worktable 1. The conveying screw 201 is rotatably mounted on the mounting base 204. There are two transmission gears 501, which are respectively fixedly installed at the ends of the two conveying screws 201. The reversing gear 502 is rotatably mounted on the side of the mounting base 204, and the reversing gear 502 meshes with the two transmission gears 501 at the same time. The conveying assembly 2 also includes a motor 205. The output end of the motor 205 provides torque to the shaft of one conveying screw 201 through a chain and a sprocket.

[0025] It should be noted that the conveying assembly 2 is also equipped with a material box 8, which is fixedly installed on the workbench 1. The needle blank is placed in the material box 8, and the material box 8 covers the conveying screw 201. At the same time, there is an opening on the side of the material box 8, which allows the needles inside the material box 8 to flow out.

[0026] Thus, simply starting the motor 205 will drive one conveyor screw 201 to rotate. This conveyor screw 201 will then drive another conveyor screw 201 to rotate synchronously via the transmission gear 501 and the reversing gear 502. At this time, if the needle blank in the material box 8 corresponds to the screw groove on the conveyor screw 201, it will fall into it and flow out from the opening on the side of the material box 8 under the action of the conveyor screw 201. Finally, it will be transported to the bottom of the stamping assembly 3. The needle blank will be located between the limiting rod 202 and the conveyor screw 201, thereby ensuring that the vibration during the stamping process will not cause the needle blank to fall off, effectively ensuring the continuity of processing.

[0027] The stamping assembly 3 includes a frame 301, a stamping head 302, and a drive component 6. The frame 301 is fixedly connected to the worktable 1. The stamping head 302 is located above the lead screw 201 and is slidably mounted on the frame 301. The die can be mounted on the side of the stamping head 302 near the conveying assembly 2. The drive component 6 is mounted on the frame 301 and drives the stamping head 302 to slide.

[0028] The drive component 6 includes a crankshaft 601, a connecting rod 602, and a flywheel 603. The crankshaft 601 is rotatably mounted on the frame 301. One end of the connecting rod 602 is rotatably sleeved on the crankshaft 601, and the other end is rotatably connected to the stamping head 302. The rotation of the crankshaft 601 will drive the stamping head 302 to slide through the connecting rod 602. The flywheel 603 is fixedly mounted on the rotating shaft of the crankshaft 601. At the same time, the crankshaft 601 and the output end of the motor 205 are driven by a chain and a sprocket.

[0029] The stamping assembly 3 also includes a fixed rod 303, a guide block 304, a compression spring 305, and a limiting block 306. The guide block 304 is fixedly installed on the stamping head 302 and its position corresponds to the blank of the needle to be stamped. The fixed rod 303 is slidably installed on the guide block 304. The limiting block 306 is fixedly installed on the stamping head 302. The compression spring 305 is located between the fixed rod 303 and the limiting rod 202. At the same time, the bottom end of the fixed rod 303 is lower than the bottom surface of the mold of the stamping head 302 under the action of the compression spring 305, so that when the stamping head 302 slides down, the fixed rod 303 first presses the blank of the needle to be stamped. The bottom end of the fixed rod 303 is provided with a groove 307. The groove 307 is V-shaped and the narrow end is far away from the bottom end of the fixed rod 303.

[0030] Thus, during the operation of motor 205, the crankshaft 601 will be driven to rotate synchronously. The rotation of crankshaft 601 will drive the stamping head 302 to slide back and forth in the middle of frame 301 via connecting rod 602. In this way, as long as the stamping die is installed on the side of stamping head 302 near worktable 1, the downward movement of stamping head 302 will drive the die to stamp the needle blank on conveying assembly 2 on worktable 1. When stamping head 302 descends, it will synchronously drive fixed rod 303 to descend, and due to the bottom end of fixed rod 303... The fixing rod 303 will first fall on the worktable 1 and press the needle blank to be processed when the die bottom surface is lower than the stamping head 302. Then the stamping head 302 will continue to slide down to drive the die to press down. This can effectively ensure the accuracy of stamping. During the process of the stamping head 302 continuing to move down, the fixing rod 303 will slide relative to the guide block 304 and compress the spring 305 to ensure that the stamping head 302 can move down stably. Then when the stamping head 302 returns to its original position, the compression spring 305 will be released to drive the fixing rod 303 to return to its original position.

[0031] It should be noted that a support platform is provided on the worktable 1 at the position corresponding to the fixed rod 303. The height of the support platform is sufficient to allow the needle blank to slide over its surface when the conveying assembly 2 moves. In this way, when the fixed rod 303 is pressed down, it can cooperate with the support platform to press the corresponding needle blank tightly. In addition, the lower die of the mold is also similar. It needs to be installed on the worktable 1 at the position corresponding to the upper die, and allow the needle blank to slide over its upper surface to ensure that the stamping process can be carried out normally.

[0032] The bending assembly 4 includes a bending rod 401, a guide seat 402, and a linkage assembly 7. The guide seat 402 is fixedly installed on the worktable 1, and the bending rod 401 is slidably installed on the guide seat 402. The top end of the bending rod 401 corresponds to the tail end of the needle blank to be processed. The linkage assembly 7 is connected between the bending rod 401 and the punch head 302. When the punch head 302 slides down, it will drive the linkage assembly 7 to rotate, thereby driving the bending rod 401 to slide up to bend the tail end of the needle blank.

[0033] The linkage assembly 7 includes a power rod 701, a transmission plate 702, and a return spring 703. The power rod 701 is slidably installed in the middle of the worktable 1 and is located below the punch head 302. Simultaneously, the punch head 302 slides down, which can drive the power rod 701 to slide down. The transmission plate 702 is rotatably installed below the worktable 1, with one end of the transmission plate 702 below the power rod 701 and the other end below the bending rod 401. When one end of the power rod 701 slides down, it drives the transmission plate 702 to rotate, which will simultaneously push the power rod 701 to slide up. The return spring 703 is installed between the bending rod 401 and the worktable 1. Under the action of the return spring 703, the bending rod 401 contacts the transmission plate 702 and causes the transmission plate 702 to rotate, thereby driving the power rod 701 to rise above the worktable 1.

[0034] Thus, when the punch head 302 moves downward, it will push the power rod 701 downward. The downward movement of the power rod 701 will push the transmission plate 702 to rotate. The rotation of the transmission plate 702 will drive the bending rod 401 to slide upward, thereby bending the tail of the needle blank. When the bending rod 401 slides upward, it will simultaneously compress the return spring 703. Thus, when the punch head 302 slides upward, the return spring 703 will drive the bending rod 401 to return to its original position, which in turn will drive the transmission plate 702 and the power rod 701 to return to their original positions.

[0035] Therefore, the complete usage process is as follows: First, neatly place the needle blanks to be processed into the material box 8, and install the upper die required for stamping on the side of the stamping head 302 near the worktable 1. Install the lower die on the corresponding position of the worktable 1. Then, start the motor 205. The motor 205 will drive one conveyor screw 201 to rotate. This conveyor screw 201 will drive another conveyor screw 201 to rotate synchronously through the transmission gear 501 and the reversing gear 502. At this time, if there is a needle blank in the material box 8 that corresponds to the screw groove on the conveyor screw 201, it will fall into it and flow out from the opening on the side of the material box 8 under the action of the conveyor screw 201. Finally, it will be transported to the bottom of the stamping assembly 3. During the operation of the motor 205, the crankshaft 601 will also rotate synchronously. The rotation of the crankshaft 601 will drive the stamping head 302 to slide back and forth in the middle of the frame 301 through the connecting rod 602. In this way, the downward movement of the stamping head 302 will drive the die. The needle blanks on the conveying assembly 2 are stamped. When the stamping head 302 descends, it simultaneously drives the fixing rod 303 to descend. Since the bottom of the fixing rod 303 is lower than the bottom surface of the die of the stamping head 302, the fixing rod 303 will first fall on the worktable 1 and press the needle blank to be processed. Then the stamping head 302 continues to descend and drives the die to press down, which effectively ensures the accuracy of stamping. When the stamping head 302 moves down, it will also push the power rod 701 down. The downward movement of the power rod 701 will push the transmission plate 702 to rotate. The rotation of the transmission plate 702 will drive the bending rod 401 to slide up, thereby bending the tail of the needle blank. After these processes are completed, the conveying assembly 2 continues to operate and will transport the processed needle blank to the next stage. In the entire processing process, loading, stamping, bending and unloading are all completed on one machine, eliminating intermediate loading, unloading and transfer links, effectively improving processing efficiency.

[0036] Furthermore, since the bending direction of the bending component 4 is opposite to the stamping direction of the stamping component 3, when processing the needle blank, both ends of the needle blank will be subjected to forces in two different directions. Compared with forces in a single direction, the bending caused by forces in two different directions will cancel each other out, thus making the processed needle blank straighter and effectively reducing the difficulty of subsequent straightening.

[0037] In the above solution, the needle blanks in the material box 8 need to fall into the screw groove of the conveying screw 201 under their own gravity in order to achieve feeding. However, the material box 8 itself is stationary. As a result, there are relatively more needle blanks at the bottom of the material box 8, which will generate a large frictional force between them under the action of gravity. This frictional force can easily cause the needle blanks to get stuck in the material box 8 and not fall into the screw groove of the conveying screw 201, which will lead to feeding failure. Therefore, this application makes further improvements: A lever 9 is fixedly installed on the surface of the stamping head 302, and a window is opened on the side of the material box 8. The end of the lever 9 away from the stamping head 302 extends into the window and contacts the needle blank. In this way, the stamping head 302 will drive the lever 9 to move synchronously during its up and down movement. The movement of the lever 9 will move the needle blank inside the material box 8 to promote the needle blank to fall into the screw groove of the conveying screw 201. In this way, continuous feeding can be effectively guaranteed, thereby ensuring processing efficiency.

Under the action of the return spring (703), the bending rod (401) contacts the transmission plate (702) and causes the transmission plate (702) to rotate, thereby driving the power rod (701) to rise above the worktable (1).
