A coating industrial robot for nonwoven fabric production

Abstract

This invention relates to the field of nonwoven fabric production, and particularly to an industrial robot for nonwoven fabric coating. It includes a coating box, with a material feeding auxiliary component installed on the outer wall of the box, a winding detection component installed on the bottom inner wall of the box, and a coating component installed on one side inner wall. The invention activates a second vibration motor to drive a transmission ball to vibrate, putting the nonwoven fabric in an active state. Subsequently, a probe structure causes the nonwoven fabric to adhere to the inner wall of a liquid storage cylinder, and is in a stretched state, which is more conducive to subsequent coating work. The coating solution in the liquid storage cylinder is sprayed onto the surface of the nonwoven fabric, causing the sliding tube and probe structure to fully penetrate into the sleeve, allowing the coating solution in the liquid storage tank to flow along the bottom end of the sleeve onto the surface of the nonwoven fabric for coating. This improves the passive extrusion stretching coating range while enhancing the quantitative coating effect of the industrial robot.

Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric production technology, and specifically relates to an industrial robot for nonwoven fabric production. Background Technology

[0002] The main manufacturing processes of non-woven bags include fabric selection, printing, lamination, and bag making. Non-woven fabric lamination uses a lamination machine to coat the non-woven fabric with plastic heated to a molten state at high temperatures. Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN114585448B, published on August 11, 2023, discloses a coating robot, including a paint supply passage connected to the paint supply side of the nozzle head; a return flow path for recovering paint that has not been discharged from the nozzle; a first filter for removing foreign matter from the paint; and a second filter for separating dissolved gases from the paint. The above embodiment can prevent the paint from drawing air from the nozzle and prevent pump wear during paint color changing and paint filling, and can effectively remove dissolved gases from the paint.

[0004] However, the device still has the following drawbacks: it cannot perform local stretching assistance work according to a specific range, and it cannot control the coating capacity of the nonwoven fabric surface in a compatible manner, thereby reducing the coating effect of nonwoven fabric production. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an industrial robot for nonwoven fabric production. It includes a coating box, a material feeding auxiliary component mounted on the outer wall of the coating box, a winding detection component mounted on the bottom inner wall of the coating box, and a coating component mounted on one side inner wall.

A second fixing block is connected between the other ends of the two sets of second compression springs. The bottom of the second fixing block is installed on the top of the connecting plate.

[0010] Furthermore, a first electric push rod is installed on one side wall of the second fixing block, and a second magnetic block is installed on the output end of the first electric push rod. The first magnetic block and the second magnetic block are magnetically connected. A third fixing block is installed on the top of the first fixing block, and a first motor is installed on one side wall of the third fixing block. A take-up roller is driven to the output end of the first motor, and several sets of through holes are equally spaced on the outer wall of the take-up roller.

[0011] Furthermore, a sleeve ring is fitted onto the outer wall of the take-up roller, and the outer wall of the sleeve ring is mounted on the top of the first fixed block. A second electric push rod is mounted on the sleeve ring, and a pressure plate is mounted on the output end of the second electric push rod. A fourth fixed block is mounted on one side wall of the take-up roller, and a third electric push rod is mounted on the fourth fixed block. A second motor is mounted on the output end of the third electric push rod, and a fixed column is drivenly connected to the output end of the second motor. Several sets of heating blocks are provided on the inner wall of the fixed column, and the outer wall of the fixed column is slidably connected to the inner wall of the take-up roller.

[0012] Furthermore, several sets of first cavities are installed at equal intervals on the outer wall of the fixed column. Each set of first cavities is equipped with a set of second air pumps, and each set of first cavities is equipped with a set of fourth electric push rods. Each set of fourth electric push rods has a monitoring structure installed on its output end.

[0013] Furthermore, the coating assembly also includes a mounting plate, one end of which is mounted on the inner wall of one side of the coating box. Two sets of fifth fixing blocks are symmetrically mounted on one side wall of the mounting plate. A set of fifth electric push rods is mounted on the corresponding side wall of each of the two sets of fifth fixing blocks. A set of mounting blocks is mounted on the output end of each set of fifth electric push rods. The bottom of each set of liquid storage cylinders is mounted on the top of one set of mounting blocks.

[0014] Furthermore, each set of liquid storage cylinders has several sets of third cavities at equal intervals on its top. Each set of third cavities has one end of a set of second compression springs, and the other end of each set of second compression springs is equipped with a set of second vibration motors. Each set of second vibration motors has a set of transmission balls connected to its output end.

[0015] Furthermore, several sets of liquid storage tanks are installed at equal intervals on the bottom of another set of mounting blocks. Each set of sleeves is installed on the bottom of one of the sets of liquid storage tanks. An electric ball valve is installed between each set of liquid storage tanks and the sleeve. Each set of sliding tubes is slidably connected inside the sleeve.

[0016] The beneficial effects of this invention are:

[0017] 1. The second vibration motor is started to drive the transmission ball to vibrate, so that the non-woven fabric is in an active state. Then, the probe structure drives the non-woven fabric to adhere to the inner wall of the liquid storage cylinder and is in a stretched state, which is more conducive to the subsequent coating work. The coating solution in the liquid storage cylinder is sprayed onto the surface of the non-woven fabric, and the sliding tube and probe structure are fully inserted into the sleeve cylinder. The coating solution in the liquid storage tank flows into the surface of the non-woven fabric along the bottom end of the sleeve cylinder to carry out the coating work. This improves the passive extrusion stretching coating range and the quantitative coating effect of the industrial robot.

[0018] 2. Start the first motor to drive the take-up roller to rotate. The take-up roller begins to rotate and collect the coated nonwoven fabric. During this process, the heating block inside the fixed column starts to heat the inner wall of the take-up roller, allowing hot air to pass through the through holes to heat the surface of the nonwoven fabric, making the coating process more thorough. Then, start the third electric push rod to push the fixed column to slide inside the take-up roller, increasing the heating range of the nonwoven fabric. Subsequently, the second air pump is used to shape the surface of the nonwoven fabric, improving the heating and shaping effect of the nonwoven fabric surface. During this process, the fourth electric push rod can be started to drive the monitoring structure for real-time monitoring, improving the detection effect of the nonwoven fabric forming accuracy.

[0019] 3. During the movement of the non-woven fabric, its surface is squeezed by several sets of extrusion rods, and protected by the buffer of the first compression spring. This avoids wear on the surface of the non-woven fabric caused by the extrusion rods, while improving the impurity removal effect of the non-woven fabric surface through passive friction. To improve the removal effect of fine particles, the first vibration motor can be started to drive several sets of extrusion rods to vibrate. Then, the first air pump can be started to fill the air bag structure, so that the air bag structure expands and softly wraps the surface of the non-woven fabric. This also causes the output ends of two sets of adsorption mud plates to attach to the surface of the non-woven fabric. Subsequently, during the passive movement of the non-woven fabric, the surface of the non-woven fabric is adsorbed and cleaned by the two sets of adsorption mud plates, which improves the friction dust removal effect and the subsequent coating effect.

[0020] 4. Activate the first electric push rod to magnetically connect the second magnetic block with the first magnetic block. Then, activate the first electric push rod to move the first fixed block closer to the second fixed block, and in the process, start to compress the second compression spring, so that the first fixed block is located close to the sealing plate. Then, the non-woven fabric passes through the auxiliary frame and the air bag structure in sequence and is located directly above the take-up roller. Then, activate the second electric push rod to drive the pressure plate to limit one end of the take-up roller. Then, disengage the electromagnetic connection between the two sets of electromagnetic blocks. After the second compression spring senses the pressure disappearance, it drives the non-woven fabric to move deeper into the coating box, which improves the elastic movement buffering effect and the limiting protection effect of the structure.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides an industrial robot for nonwoven fabric production, specifically a lamination box 1. Exemplary examples include... Figure 1 As shown, a material conveying auxiliary component 2 is installed on the outer wall of the coating box 1, a winding detection component 3 is installed on the bottom inner wall of the coating box 1, and a coating component 4 is installed on one side inner wall.

[0035] For example, such as Figure 2 As shown, the material conveying auxiliary component 2 includes a sealing plate 201. One end of the sealing plate 201 is installed on the outer wall of the coating box 1. A sliding groove is provided on the sealing plate 201. An air bag structure 202 is installed on the inner wall of the sliding groove. An adsorbent mud plate 203 is installed on the outer wall of the air bag structure 202. A first air pump 204 is installed on one side wall of the sealing plate 201. The output end of the first air pump 204 is connected to the air bag structure 202. A fixing plate 205 is installed on one side wall of the sealing plate 201. A first vibration motor 206 is installed on one side wall of the fixing plate 205. An auxiliary frame 207 is drivenly connected to the output end of the first vibration motor 206. Several sets of first compression springs 208 are installed at equal intervals on the inner wall of each set of auxiliary frames 207. A set of extrusion rods 209 are installed on the other end of each set of first compression springs 208.

[0036] During the movement of the nonwoven fabric, its surface is squeezed by several sets of extrusion rods 209, and protected by the buffer of the first compression spring 208. This avoids wear on the surface of the nonwoven fabric caused by the extrusion rods 209, while improving the impurity removal effect of the nonwoven fabric surface through passive friction. To improve the removal effect of small particles, the first vibration motor 206 can be started to drive several sets of extrusion rods 209 to vibrate. Then, the first air pump 204 is started to fill the air bag structure 202, so that the air bag structure 202 expands and softly wraps the surface of the nonwoven fabric. It also drives the output ends of two sets of adsorption mud plates 203 to attach to the surface of the nonwoven fabric. Then, during the passive movement of the nonwoven fabric, the two sets of adsorption mud plates 203 adsorb and clean the surface of the nonwoven fabric, improving the friction dust removal effect and the subsequent coating effect.

[0037] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the winding detection assembly 3 includes a connecting plate 301. The bottom of the connecting plate 301 is installed on the bottom inner wall of the coating box 1. A sliding cavity 302 is formed on the top of the connecting plate 301. A first fixing block 303 is slidably connected in the sliding cavity 302. A first magnetic block 304 is installed on one side wall of the first fixing block 303. Two sets of second compression springs 305 are symmetrically installed on one side wall of the first magnetic block 304. A second fixing block 306 is connected between the other ends of the two sets of second compression springs 305. The bottom of the second fixing block 306 is mounted on the top of the connecting plate 301. A first electric push rod 307 is mounted on one side wall of the second fixing block 306. A second magnetic block 308 is mounted on the output end of the first electric push rod 307. The first magnetic block 304 and the second magnetic block 308 are magnetically connected. A third fixing block 309 is mounted on the top of the first fixing block 303. A first motor 310 is mounted on one side wall of the third fixing block 309. A take-up roller 311 is drivenly connected to the output end of the first motor 310. The outer wall of the take-up roller 311... Several sets of through holes 312 are evenly spaced on the upper part of the take-up roller 311. A sleeve ring 313 is fitted onto the outer wall of the take-up roller 311. The outer wall of the sleeve ring 313 is mounted on the top of the first fixing block 303. A second electric push rod 314 is mounted on the sleeve ring 313. A pressure plate 315 is mounted on the output end of the second electric push rod 314. A fourth fixing block 316 is mounted on one side wall of the take-up roller 311. A third electric push rod 317 is mounted on the fourth fixing block 316. A second motor 318 is mounted on the output end of the third electric push rod 317. A fixed column 319 is drivenly connected to the output end of the second motor 318. Several sets of heating blocks are provided on the inner wall of the fixed column. The outer wall of the fixed column 319 is slidably connected to the inner wall of the take-up roller 311. Several sets of first cavities 320 are installed at equal intervals on the outer wall of the fixed column 319. A set of second air pumps 321 is provided in one set of first cavities 320, and a set of fourth electric push rods 322 is provided in another set of first cavities 320. A set of monitoring structures 323 is installed on the output end of each set of fourth electric push rods 322.

[0038] When the nonwoven fabric needs to undergo a coating process during production, the first electric push rod 307 is activated to drive the second magnetic block 308 to magnetically connect with the first magnetic block 304. Then, the first electric push rod 307 is activated to drive the first fixing block 303 to move closer to the second fixing block 306, and in the process, the second compression spring 305 is squeezed, so that the first fixing block 303 is located close to the sealing plate 201. Then, the nonwoven fabric passes through the auxiliary frame 207 and the air bag structure 202 in sequence and is located directly above the take-up roller 311. Then, the second electric push rod 314 is activated to drive the pressure plate 315 to limit one end of the take-up roller 311. Then, the electromagnetic connection between the two sets of electromagnetic blocks is disengaged. After the second compression spring 305 senses the pressure disappearance, it drives the nonwoven fabric to move deeper into the coating box 1, which improves the elastic movement buffering effect and the limiting protection effect of the structure.

[0039] The first motor 310 is started to drive the take-up roller 311 to rotate. The take-up roller 311 begins to rotate and collect the coated nonwoven fabric. During this process, the heating block inside the fixed column 319 starts to heat and passively heats the inner wall of the take-up roller 311. This allows hot air to pass through the through hole 312 to heat the surface of the nonwoven fabric, making the coating process more thorough. Then, the third electric push rod 317 is started to push the fixed column 319 to slide inside the take-up roller, increasing the heating range of the nonwoven fabric. Subsequently, the second air pump 321 is used to shape the surface of the nonwoven fabric, improving the heating and shaping effect of the nonwoven fabric surface. During this process, the fourth electric push rod 322 can be started to drive the monitoring structure 323 for real-time monitoring, improving the detection effect of the nonwoven fabric forming accuracy.

[0040] For example, such as Figure 7 , Figure 8 and Figure 9As shown, the coating assembly 4 includes a mounting plate 401. One end of the mounting plate 401 is mounted on the inner wall of one side of the coating box 1. Two sets of fifth fixing blocks 402 are symmetrically mounted on one side wall of the mounting plate 401. A set of fifth electric push rods 403 is mounted on the corresponding side wall of each set of fifth fixing blocks 402. A set of mounting blocks 404 is mounted on the output end of each set of fifth electric push rods 403. Several sets of liquid storage cylinders 405 are evenly spaced on the top of one set of mounting blocks 404. Several sets of second cavities 406 are evenly spaced on the inner wall of each set of liquid storage cylinders 405. A set of micro valves 407 is provided in each set of second cavities 406. Several sets of third cavities 408 are evenly spaced on the top of each set of liquid storage cylinders 405. One end of a set of second compression springs 409 is provided in each set of third cavities 408. The other end of each set of second compression springs 409 is... Each set of two sets of second vibration motors 410 is installed, and each set of second vibration motors 410 is connected to a set of transmission balls 411 at the output end. Each set of liquid storage cylinders 405 is equipped with a set of pressure sensors 412 on the inner wall. Several sets of liquid storage tanks 413 are installed at equal intervals on the bottom of another set of mounting blocks 404. Each set of liquid storage tanks 413 is connected to a set of sleeves 414 at the bottom. Each set of liquid storage tanks 413 and sleeves 414 is connected to a set of electric ball valves 415. Each set of sleeves 414 is equipped with a set of sliding plates 416 on the inner wall. Each set of sliding plates 416 is equipped with one end of a set of third compression springs 417 at the bottom. Each set of third compression springs 417 is equipped with a set of sliding tubes 418 at the other end. Each set of sliding tubes 418 is slidably connected inside the sleeves 414. Each set of sliding tubes 418 is equipped with a set of probe structures 419 at the bottom.

[0041] During the coating process, the fifth electric push rod 403 is activated to move several sets of liquid storage cylinders 405 and connecting cylinders 414 towards the nonwoven fabric. This causes several sets of transmission balls 411 to contact the bottom surface of the nonwoven fabric. During this process, the second vibration motor 410 is activated to vibrate the transmission balls 411, keeping the nonwoven fabric in an active state. Then, one set of the fifth electric push rod 403 is activated to lower several sets of probe structures 419, pressing down on the surface of the nonwoven fabric. Continuous pressing causes the probe structures 419 to press the nonwoven fabric against the inner wall of the liquid storage cylinder 405, placing it in a stretched state, which is more conducive to subsequent coating work. The probe structures 419 provide pressure to the pressure sensor 412 to the specified pressure. After the force is applied, the pressure sensor 412 sends signals to several sets of micro valves 407, causing the coating solution in the storage tank 405 to be sprayed onto the surface of the nonwoven fabric. The solution wasted during spraying flows into the storage tank 405, settles, and is then recycled. During the extrusion process, the probe structure 419 passively compresses the third compression spring 417 until the sliding tube 418 and the probe structure 419 are fully inserted into the sleeve 414. At this time, the electric ball valve 415 is opened, allowing the coating solution in the storage tank 413 to flow along the bottom of the sleeve 414 onto the surface of the nonwoven fabric for coating. This improves the passive extrusion stretching coating range and enhances the quantitative coating effect of the industrial robot.

[0042] The second vibration motor 410 is started to drive the transmission ball 411 to vibrate, so that the non-woven fabric is in an active state. Then, the probe structure 419 drives the non-woven fabric to adhere to the inner wall of the liquid storage cylinder 405 and is in a stretched state, which is more conducive to the subsequent coating work. The coating solution in the liquid storage cylinder 405 is sprayed onto the surface of the non-woven fabric, and the sliding tube 418 and the probe structure 419 are fully inserted into the sleeve cylinder 414, so that the coating solution in the liquid storage tank 413 flows into the surface of the non-woven fabric along the bottom end of the sleeve cylinder 414 to carry out the coating work. This improves the passive extrusion stretching coating range and the quantitative coating effect of the industrial robot.

[0043] The first motor 310 is started to drive the take-up roller 311 to rotate. The take-up roller 311 begins to rotate and collect the coated nonwoven fabric. During this process, the heating block inside the fixed column 319 starts to heat and passively heats the inner wall of the take-up roller 311. This allows hot air to pass through the through hole 312 to heat the surface of the nonwoven fabric, making the coating process more thorough. Then, the third electric push rod 317 is started to push the fixed column 319 to slide inside the take-up roller, increasing the heating range of the nonwoven fabric. Subsequently, the second air pump 321 is used to shape the surface of the nonwoven fabric, improving the heating and shaping effect of the nonwoven fabric surface. During this process, the fourth electric push rod 322 can be started to drive the monitoring structure 323 for real-time monitoring, improving the detection effect of the nonwoven fabric forming accuracy.

[0044] During the movement of the nonwoven fabric, its surface is squeezed by several sets of extrusion rods 209, and protected by the buffer of the first compression spring 208. This avoids wear on the surface of the nonwoven fabric caused by the extrusion rods 209, while improving the impurity removal effect of the nonwoven fabric surface through passive friction. To improve the removal effect of small particles, the first vibration motor 206 can be started to drive several sets of extrusion rods 209 to vibrate. Then, the first air pump 204 is started to fill the air bag structure 202, so that the air bag structure 202 expands and softly wraps the surface of the nonwoven fabric. It also drives the output ends of two sets of adsorption mud plates 203 to attach to the surface of the nonwoven fabric. Then, during the passive movement of the nonwoven fabric, the two sets of adsorption mud plates 203 adsorb and clean the surface of the nonwoven fabric, improving the friction dust removal effect and the subsequent coating effect.

[0045] The first electric push rod 307 is activated to drive the second magnetic block 308 to magnetically connect with the first magnetic block 304. Then, the first electric push rod 307 is activated to drive the first fixed block 303 to move closer to the second fixed block 306. During this process, the second compression spring 305 is compressed, so that the first fixed block 303 is positioned close to the sealing plate 201. Then, the nonwoven fabric passes through the auxiliary frame 207 and the inflatable bag structure 202 in sequence and is positioned directly above the take-up roller 311. Then, the second electric push rod 314 is activated to drive the pressure plate 315 to limit one end of the take-up roller 311. Then, the electromagnetic connection between the two sets of electromagnetic blocks is disengaged. After the second compression spring 305 senses the pressure disappearance, it drives the nonwoven fabric to move deeper into the coating box 1. This improves the elastic movement buffering effect while improving the limiting and protection effect of the structure.
