Description

Technical Field

[0001] The invention belongs to the technical field of punching, and in particular relates to a spinneret punching device and a method thereof. Background Art

[0002] The function of the spinneret is to transform the viscous polymer melt or solution into a thin flow with a specific cross-section through micropores, and solidify it into thin strips through a coagulation medium such as air or a coagulation bath. The spinneret works at a relatively high temperature and pressure, and requires pressure resistance, corrosion resistance and sufficient mechanical strength. The spinneret can be divided into ordinary and special-shaped spinnerets and composite spinnerets. According to the type and specification of the fiber, there are different specifications, shapes, hole types, materials, etc. The geometry of the spinneret hole directly affects the flow characteristics of the melt, thereby affecting the fiber forming. The spinneret hole is usually composed of guide holes and capillaries. When the melt is squeezed from a larger space into a very small micropore, the flow velocity increases sharply. In order to control the shear velocity of the melt flow and obtain a larger pressure difference source, conical and hyperbolic guide holes are better.

Unloading modules are installed on both sides of the processing base, and unloading guide plates are installed on the unloading modules. The unloading guide plates are made of elastic rubber material.

[0015] A method for a spinneret punching device, comprising the following steps: Step 1: Start the motor, the gear shaft connected to the motor rotates, and the transmission gear set installed on the gear shaft makes multiple gear shafts rotate together. The intermediate gear rotates with the gear shaft and transmits power to the main gear. The main gear rotates, and the gravity chain meshing with the main gear rotates in the circular groove to transmit the spinneret; Step 2: In step 1, while the gravity chain is rolling, the middle clamp block and the end clamp block on the same vertical plane of the feeding end first clamp one end of the spinneret in the clamping groove 1, and as the gravity chain rolls, when the end clamp block rolls to the same height plane as the middle clamp block, the end clamp block automatically clamps the other end of the spinneret, and the spinneret feeding in this process is mechanically clamped; Step 3: When drilling, the push plate cylinder pushes the auxiliary support plate upward out of the sinking hole so that the auxiliary support plate is close to the bottom surface of the spinneret; Step 4: The rear electric slide moves on the rear slide rail to align the drill bit with the spinneret.

After the punching is completed, the spinneret continues to move with the rolling of the gravity chain. When the gravity chain moves to another unloading position, the middle clamp on the left rolls downward and automatically detaches from the spinneret. One end of the spinneret relies on gravity to tilt toward the unloading guide. When it moves to a certain distance and the gravity is greater than the clamping force of the end clamp, the spinneret automatically falls off and slides out of the unloading module along the unloading guide.

[0022] like Figure 1 As shown, the present invention provides a spinneret punching device, including a feeding module 4 and a punching module 1, the feeding module 4 and the punching module 1 are installed on a processing base 3, the punching module 1 includes a punching seat 103 and a drill 5, and during specific operation, the spinneret is fed by the feeding module 4 installed on the processing base 3, and the feeding direction of the spinneret is as shown in FIG. Figure 1 In the direction of the arrow in FIG. 1 , the feeding module 4 moves the spinneret to the bottom of the punching module 1 and punches the spinneret through the drill bit 5 .

[0023] Embodiment 1 like Figure 1-Figure 3 As shown, a motor 105 is installed on the punching seat 103, and the bottom end of the motor 105 extends into the punching seat 103. A gravity platform 104 is installed on the top of the motor 105. The gravity platform 104 ensures the stability of the movement of the punching seat 103 and indirectly ensures the accuracy of the position of the drill bit 5. A punching lifting cylinder 106 is installed on the other end of the gravity platform 104. The punching lifting cylinder 106 is installed on the processing base 3. The function of the punching lifting cylinder 106 is to raise and lower the entire punching seat 103 along the vertical direction. When the feeding module 4 moves the spinneret to the bottom of the drill bit 5, the punching lifting cylinder 106 pulls down the gravity platform 104, and the punching seat 103 and the motor 105 move down together with the gravity platform 104. When the drill bit 5 is about to touch the top surface of the spinneret, the drill bit 5 rotates and cooperates with the punching lifting cylinder 106 to realize the punching operation on the spinneret.

[0024] Furthermore, in order to install multiple drill bits in the drilling seat 103, as shown in FIG. Figure 4As shown, a plurality of grooves 107 are provided in the punching seat 103, and the grooves 107 are arranged in a circle at the bottom end of the punching seat 103. A linkage seat 113 is rotatably installed in the groove 107, and the drill bit 5 is installed in the linkage seat 113. The linkage seat 113 has its own cylinder, and the selected drill bit is pushed downward by the cylinder of the linkage seat 113. Since multiple drill bits are installed in the punching seat 103, when the installed drill bits are the same size, the lowest points of the drill bits are on the same horizontal plane. The linkage seat 113 with its own cylinder can realize the downward movement of a single drill bit, thereby avoiding interference between the installed multiple drill bits and affecting normal drilling.

[0025] Furthermore, if Figure 4 As shown, in order to reduce the driving components of a single drill bit on the drilling seat 103, a gear 108 is provided on the outer fixed sleeve of the linkage seat 113. The gear 108 is rotatably connected to the drilling seat 103. The heights of the gears 108 in different grooves 107 are not on the same horizontal plane. Figure 4 As shown, another linkage seat 113 is provided with a second gear 117 outside the fixed sleeve, and the height of the second gear 117 and the gear 1 108 are not on the same horizontal line. By controlling the rotation of the gear 108 or the gear 117, the linkage seat 113 is driven to rotate together, and finally the rotation of the drill bit 5 itself is realized; The punching seat 103 is provided with a cavity 109, and an internal cylinder 110 is installed in the cavity 109. The bottom end of the internal cylinder 110 is fixedly sleeved with a power gear 111. The outer ring of the gear 108 extends into the cavity 109 and meshes with the power gear 111. Specifically, the top of the internal cylinder 110 is fixedly installed at the bottom end of the motor 105. The diameter of the cavity 109 is larger than the diameter of the power gear 111. The internal cylinder 110 controls the power gear 111 to move up and down in the cavity 109, and the power gear 111 moves to different heights and different The gears are meshed, and then the drill bit for drilling is selected. At this time, the motor 105 connected to the drilling seat 103 is rotationally connected. When the motor 105 is working, the internal cylinder 110 rotates with the motor 105. Taking the meshing of the power gear 111 and the gear 108 as an example, the internal cylinder 110 pushes the power gear 111 downward to make it mesh with the gear 108. At this time, the power gear 111 transmits power to the gear 108, and the linkage seat 113 is driven to rotate in the groove 107 through the gear 108, thereby realizing the rotation of the drill bit 5.

[0026] Embodiment 2 On the basis of the above-mentioned embodiment 1, in order to install drill bits of various sizes in the punch seat 103 and realize simple installation and removal of the drill bits and the punch seat 103, as shown in FIG. Figure 4As shown, a drill hole 116 is opened in the linkage seat 113, and a drill base 114 is installed in the drill hole 116. The drill base 114 is fixedly installed in the drill hole 116 by a fastener 112. The installation and disassembly of the drill bit 5 are completed by assembling and disassembling the drill base 114. The drill base 114 is internally threadedly connected with a threaded seat 115, and the drill bit 5 is fixedly installed at the bottom end of the threaded seat 115. The diameters of the drill bits 5 installed on different threaded seats 115 are different. The drill base 114 and the drill bit 5 are installed separately, so that the drill can be easily and quickly at any time.

[0027] Embodiment 3 Based on the above-mentioned embodiment 2, Figure 1 and Figure 2 As shown, the feeding module 4 includes a side plate 417 symmetrically mounted on the processing base 3. The side plate 417 and the processing base 3 can be welded in one piece. A circular groove 408 is provided on the inner side of the side plate 417. A plurality of rotating shafts 401 are rotatably mounted in the circular groove 408. Figure 5 and Figure 6 As shown, a connecting rod 405 is installed above the rotating shaft 401, and a power assembly is installed on one end of the rotating shaft 401 and the connecting rod 405. The connecting rod 405 is driven by the power assembly to roll in the circular groove 408. The position of the rotating shaft 401 in the circular groove 408 remains unchanged. The connecting rods 405 at different positions are respectively installed with middle clamping blocks 407 and end clamping blocks 402. The spinneret is clamped and fixed by the mutual cooperation between the middle clamping blocks 407 and the end clamping blocks 402 or the two adjacent middle clamping blocks 407.

[0028] In order to ensure the stability of the spinneret, Figure 5 and Figure 6 As shown, a gravity seat 404 is installed on the connecting rod 405, and the middle clamp block 407 and the end clamp block 402 are installed on the gravity seat 404. The gravity of the gravity seat 404 itself ensures the stability of the structure on the entire connecting rod 405, ensuring that it can stably transport the spinneret.

[0029] In order to make the power coordination between the rotating shaft 401 and the connecting rod 405, the structure of the power assembly is as follows Figure 8 As shown, a main gear 410 is sleeved on one end of the rotating shaft 401, and the main gear 410 is located in the circular groove 408. Gravity chains 409 are meshed on multiple main gears 410, and a connecting rod 405 is fixedly installed on the gravity chain 409. When the main gear 410 rotates, the gravity chain 409 rolls on the main gear 410, thereby driving the connecting rod 405 to roll in the circular groove 408, thereby realizing the transportation of the spinneret.

[0030] A gear shaft 413 is rotatably installed on the side vertical plate 417, and an intermediate gear 414 is sleeved on the gear shaft 413. The intermediate gear 414 is located between the two rotating shafts 401 distributed up and down, and the intermediate gear 414 is meshed with the main gear 410. A transmission gear set 411 is sleeved on the other end of the gear shaft 413, and the transmission gear set 411 is located on one side of the side vertical plate 417. A driving motor 412 is installed at one end of the side vertical plate 417, and the driving motor 412 is fixedly connected to the gear shaft 413 located at the end. During specific operation, the driving motor 412 works, and the gear shaft 413 connected to the driving motor 412 rotates. The transmission gear installed on the gear shaft 413 makes multiple gear shafts 413 rotate synchronously, thereby transmitting power to the main gear through the intermediate gear to realize the rotation of the main gear.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, the method of installing the end clamps 402 and the middle clamps 407 on the connecting rods 405 at different positions is as follows. Specifically, taking the connecting rods 405 installed in upper and lower rows as an example, among the connecting rods 405 in the upper row, the connecting rods 405 located at both ends are installed with end clamps 402, and the remaining connecting rods 405 are installed with middle clamps 407.

[0032] Combine the method of installing the end clamp 402 and the middle clamp 407 on the connecting rod 405 at different positions, such as Figure 5 and Figure 6 As shown, a clamping groove 403 is provided on one side of the end clamping block 402, and clamping grooves 406 corresponding to the height and depth of the clamping groove 403 are provided on both sides of the middle clamping block 407. The method for clamping the spinneret is as follows: The end clamp 402 and the middle clamp 407 located on the right side thereof clamp the spinneret: when the end clamp 402 and the middle clamp 407 move to one end of the feeding, and the end clamp 402 is located above the middle clamp 407, the spinneret is clamped into the clamping groove 1 403 by the robot, and while the connecting rod 405 rolls, the robot clamps the spinneret and moves together with the end clamp 402, and when the middle clamp 407 flips to the upper position, the other section of the spinneret is clamped in the clamping groove 2 406.

[0033] The method of clamping the spinneret by two adjacent middle clamping blocks 407 is the same as the method of clamping the spinneret by the end clamping block 402 and the middle clamping block 407 located on the right side thereof. The technology of clamping the spinneret by the manipulator is the existing technology and will not be described here.

[0034] Unloading of the spinneret: Taking the spinneret clamped by the end clamp 402 and the middle clamp 407 located on the right side as an example, when the end clamp 402 moves to the unloading position, as the connecting rod 405 continues to roll, the end clamp 402 rolls downward, and the end clamp 402 automatically separates from the spinneret. While the middle clamp 407 moves, one end of the spinneret tilts downward due to its own gravity. When the middle clamp 407 moves to a certain position, when the gravity of the spinneret is greater than the clamping force of the middle clamp 407, the spinneret automatically separates from the middle clamp, and unloading is completed.

[0035] At the same time, if Figure 1 and Figure 7 As shown, a plurality of sinking holes 301 are evenly spaced in the processing base 3, a plurality of push plate cylinders 416 are symmetrically installed in the sinking holes 301, an auxiliary bearing plate 415 is installed on the top of the push plate cylinder 416, and the length of the auxiliary bearing plate 415 is less than the distance between two adjacent rotating shafts 401. The position of the spinneret is limited from bottom to top by the auxiliary bearing plate 415, so as to facilitate the accuracy of the spinneret punching.

[0036] In order to cooperate with the spinneret feeding module, such as Figure 1 and Figure 3 As shown, a rear slide rail 102 is installed at the rear end of the processing base 3 , a rear electric slide seat 101 is slidably connected to the rear slide rail 102 , and a drilling and lifting cylinder 106 is installed on the rear electric slide seat 101 .

[0037] Furthermore, if Figure 1 As described, a material discharge module 2 is installed on both sides of the processing base 3, and a material discharge guide plate 201 is installed on the material discharge module 2. The material discharge guide plate 201 is made of elastic rubber material. The position of the spinneret is limited by the material discharge guide plate 201, so that the spinneret can slide down easily.

[0038] The present invention also provides a method for a spinneret punching device, wherein a driving motor 412 is started, a gear shaft 413 connected to the driving motor 412 rotates, a transmission gear set 411 installed on the gear shaft 413 causes multiple gear shafts 413 to rotate together, an intermediate gear 414 rotates along with the gear shaft 413 and transmits power to a main gear 410, the main gear 410 rotates, and a gravity chain 409 meshing with the main gear 410 performs a rotary motion in a circular groove 408 to transport the spinneret; In the above steps, while the gravity chain 409 is rolling, the middle clamp block 407 and the end clamp block 402 on the same vertical plane of the feeding end first clamp one end of the spinneret in the clamping groove 403, and as the gravity chain 409 rolls, when the end clamp block 402 rolls to the same height plane as the middle clamp block 407, the end clamp block 402 automatically clamps the other section of the spinneret, and the spinneret in this process is mechanically clamped; When drilling, the push plate cylinder 416 pushes the auxiliary carrier plate 415 upwards into the sink hole 301, so that the auxiliary carrier plate 415 is close to the bottom surface of the spinneret, the rear electric slide 101 moves on the rear slide rail 102 to align the drill bit 5 with the spinneret, the internal cylinder 110 drives the power gear 111 to move up and down linearly, so that the power gear 111 and the corresponding gear 108 are meshed, the motor 105 drives the internal cylinder 110 and the power gear 111 to rotate, and the linkage seat 113 is rotated through the gear 108, the drill base 114 pushes the drill bit 5 downward, and drives the drill bit 5 to perform the drilling operation through the linkage seat 113; After the punching is completed, the spinneret continues to move with the rolling of the gravity chain 409. When the gravity chain 409 moves to another unloading position, the middle clamp 407 on the left rolls downward and automatically detaches from the spinneret. One end of the spinneret relies on gravity to tilt toward the unloading guide plate 201. When it moves to a certain distance and the gravity is greater than the clamping force of the end clamp 402, the spinneret automatically falls off and slides out of the unloading module 2 along the unloading guide plate 201.
