Description

Technical Field

[0001] The present invention relates to the field of metal surface polishing, and specifically to a rapid polishing method for card clothing used in textiles. Background Art

[0002] The polishing of card clothing racks for the textile industry mainly adopts two methods at present. One is chemical polishing. During the chemical polishing process, since the rack is immersed in a chemical polishing solution for a long time to polish the surface of the rack, it will cause the inside of the rack to be easily damaged by the polishing solution, thus affecting the physical properties of the rack itself. It is difficult to control the polishing degree, resulting in problems such as being not durable and easily damaged, which affect subsequent use. Moreover, chemical polishing will produce a large amount of acid-containing wastewater. If it is directly discharged without treatment, it will cause serious damage to the environment, and the cost will be greatly increased for harmless treatment. The other is physical polishing. Although physical polishing has little impact on the physical properties of the rack itself, the slow polishing processing speed will also lead to the problem of low overall polishing efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a rapid polishing method for card clothing used in textiles that can efficiently and quickly polish card clothing racks.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A rapid polishing method for card clothing used in textiles, comprising the following steps:

[0005] Step S1: Immerse a single rack of the card clothing in a container filled with a phosphoric acid solution with a concentration of 85%, connect a DC power supply, and remove the oxide layer formed by natural oxidation on the surface of the rack through continuous electrolysis. The immersion time is 15 - 35 minutes;

[0006] Step S2: Send the rack processed in Step S1 into the first cleaning chamber to remove the residual phosphoric acid solution and reaction products on the surface of the rack. The cleaning time is 5 - 10 minutes to obtain the rack to be processed;

[0007] Step S3: Use the first automatic traction device to tractionly pull the rack to be processed obtained in Step S2 into the circulating polishing track for polishing the root position of the rack teeth. The circulating polishing track is longitudinally annularly arranged, and a plurality of obliquely arranged polishing wheels are fixedly provided on both the upper and lower layers corresponding to the upper and lower surfaces of the rack. The polishing wheels are driven by a motor to rotate at a high speed, and the rotation direction forms an angle with the traveling direction of the rack. The angle is greater than or equal to 90° and less than 180°. The polishing processing speed of the rack in the circulating polishing track is 15 - 35 m / min, the polishing rotation speed is 20 - 35 rpm, and the polishing pressure is 35 - 70 g / cm 2 ;

[0008] Step S4: Use the second automatic traction device to pull the rack that has completed the polishing process in Step S3 into the tooth tip polishing track for polishing the tooth tip position of the rack. The tooth tip polishing track is provided with a plurality of polishing cloth wheels driven by motors to rotate at high speed and obliquely arranged corresponding to the upper and lower surfaces of the tooth tips of the rack. The rotation direction of the polishing cloth wheels is set opposite to the obliquely extending direction of the tooth tips of the rack. The polishing cloth wheels polish the common edges of the two mutually perpendicular planes of the tooth tips. The rotation direction of the polishing cloth wheels forms an angle with the advancing direction of the rack, and the angle is greater than or equal to 90° and less than 180°. The polishing speed of the rack in the tooth tip polishing track is 20 - 45 m / min, the polishing rotation speed is 15 - 40 rpm, and the polishing pressure is 25 - 50 g / cm 2 ;

[0009] Step S5: Place the rack processed in Step S4 in the second cleaning chamber to clean the solid particles and other impurities on the surface of the rack. The cleaning treatment time is 3 - 8 minutes;

[0010] Step S6: Use a drying device to dry the surface of the rack cleaned in Step S5. After drying, cool the rack itself to make its temperature drop to the natural temperature. The drying treatment time is 5 - 8 minutes, and the cooling treatment time is 3 - 5 minutes;

[0011] Step S7: Perform rust prevention treatment on the surface of the rack that has completed the drying and cooling treatments in Step S6. Install a rust prevention layer on the upper and lower surfaces of the rack to reduce the possibility of oxidation of the rack surface during long - term operation;

[0012] Step S8: Remove the rack that has completed the rust prevention treatment in Step S7 to complete the polishing treatment of a single rack.

[0013] Furthermore, an automatic wax feeding device is also provided under the lower part of the circulating polishing track in Step S3. The automatic wax feeding device applies polishing wax to the upper and lower surfaces of the rack. The polishing wheels located under the circulating polishing track polish the upper and lower surfaces of the rack again so that the polishing wax can be evenly applied to the upper and lower surfaces of the rack. There is also an optional Step S6.5 between Step S6 and Step S7, that is, use a high - pressure water supply device to pump out the wax - removing aqueous solution to wash the upper and lower surfaces of the rack to remove the polishing wax on the upper and lower surfaces of the rack.

[0014] Furthermore, there is also an optional Step S1.5 between Step S1 and Step S2, that is, use a high - pressure air outlet device to blow off, remove, and collect the residual phosphoric acid solution on the surface of the rack after the chemical immersion in Step 1 in the first pretreatment chamber. There is also an optional Step S2.5 between Step S2 and Step S3, that is, use a high - pressure air outlet device to blow off, remove, and collect the residual phosphorus - containing solution on the surface of the rack after the cleaning treatment in Step 2 in the second pretreatment chamber.

[0015] Further, it further includes step S9, that is, collecting the phosphorus-containing solution and phosphorus-containing sewage that cannot be normally subjected to rack surface treatment after long-time treatment in steps S1 and S2 and performing phosphorus removal treatment, adding a flocculant or an oxidant to the phosphorus-containing solution for chemical phosphorus removal of the phosphorus-containing solution and phosphorus-containing sewage.

[0016] Further, it further includes step S9, that is, collecting the phosphorus-containing solution and phosphorus-containing sewage that cannot be normally subjected to rack surface treatment after long-time treatment in steps S1, step S1.5, step S2, and step S2.5 and performing phosphorus removal treatment, adding a flocculant or an oxidant to the phosphorus-containing solution for chemical phosphorus removal of the phosphorus-containing solution and phosphorus-containing sewage.

[0017] The beneficial effects of the present invention are as follows: The present invention separately polishes the tooth roots and tooth tips of the card clothing rack through two separate polishing processes. The non-interfering processing method can efficiently process the respective surfaces, avoiding the problem in the prior art that during the overall surface polishing process, both the processing degree required for tooth root polishing and the processing degree required for tooth tip polishing are considered, resulting in mutual constraints between the two. The design of two separate polishing processes has lower requirements for the accuracy of the polishing equipment, and the total duration of the polishing process is relatively shorter. It is more efficient and the cost required for polishing is also reduced. On the other hand, the overall polishing method in the prior art may have a certain impact on the structural strength of the rack itself, while the design of secondary polishing in the present invention does not need to consider the mutual influence between the tooth root and tooth tip during the polishing process at all. The structural strength of the rack itself after polishing may be relatively higher than that of the existing polishing methods. At the same time, compared with some chemical polishing treatment methods, the technical solution of the present invention avoids the possible influence of organic solvents or organic compounds on the material properties of the rack during the chemical polishing process, and retains the material properties of the rack itself to the greatest extent possible, and the structural strength is not affected by organic solvents or organic compounds. Specific embodiments

[0018] In order to make the technical means, innovative features and functions achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0019] The method for rapidly polishing a card clothing for textiles of the present invention includes the following steps:

[0020] Step S1: Immerse a single rack of the card clothing in a container filled with a phosphoric acid solution with a concentration of 85%, connect a DC power supply, and remove the oxide layer formed by natural oxidation on the surface of the rack through continuous electrolysis. The immersion time is 15 - 35 minutes;

[0021] Step S2: Send the rack processed in step S1 into the first cleaning chamber to remove the residual phosphoric acid solution and reaction products on the surface of the rack. The cleaning treatment time is 5 - 10 minutes, thereby obtaining the rack to be processed;

[0022] Step S3: The rack to be processed obtained in Step S2 is pulled into the circular polishing track by the first automatic traction device for polishing the root position of the rack teeth. The circular polishing track is longitudinally annularly arranged, and a plurality of obliquely arranged polishing wheels are fixedly provided at the upper and lower surfaces corresponding to the upper and lower surfaces of the rack. The polishing wheels are driven by motors to rotate at high speed, and the rotation direction forms an angle with the advancing direction of the rack. The angle is greater than or equal to 90° and less than 180°. The polishing speed of the rack in the circular polishing track is 15 - 35 m / min, the polishing rotation speed is 20 - 35 rpm, and the polishing pressure is 35 - 70 g / cm 2 ;

[0023] Step S4: The rack after the polishing process in Step S3 is pulled into the tooth tip polishing track by the second automatic traction device for polishing the tooth tip position of the rack. A plurality of polishing cloth wheels driven by motors to rotate at high speed and obliquely arranged are provided at the upper and lower surfaces corresponding to the upper and lower surfaces of the rack tooth tips. The rotation direction of the polishing cloth wheels is arranged in the opposite direction to the obliquely extending direction of the rack tooth tips. The polishing cloth wheels perform grinding and polishing on the common edges of the two mutually perpendicular planes of the tooth tips. The rotation direction of the polishing cloth wheels forms an angle with the advancing direction of the rack. The angle is greater than or equal to 90° and less than 180°. The polishing speed of the rack in the tooth tip polishing track is 20 - 45 m / min, the polishing rotation speed is 15 - 40 rpm, and the polishing pressure is 25 - 50 g / cm 2 ;

[0024] Step S5: The rack processed in Step S4 is placed in the second cleaning chamber for cleaning the solid particles and other impurities on the surface of the rack. The cleaning time is 3 - 8 minutes;

[0025] Step S6: The surface of the rack cleaned in Step S5 is dried by a drying device. After drying, the rack is cooled to its natural temperature. The drying time is 5 - 8 minutes, and the cooling time is 3 - 5 minutes;

[0026] Step S7: Anti-rust treatment is performed on the surface of the rack after drying and cooling in Step S6. An anti-rust layer is added to the upper and lower surfaces of the rack to reduce the possibility of oxidation of the rack surface under long-term working conditions;

[0027] Step S8: The rack after the anti-rust treatment in Step S7 is taken off to complete the polishing process of a single rack.

[0028] In the practical application of the present invention, in step S4, the polishing cloth wheel not only polishes the edges shared by the pairwise perpendicular planes of the tooth tips, but also polishes the tops of the tooth tips, so that there are almost no burrs at the tooth tip positions of the overall rack. This avoids the problem that after the rack is assembled into card clothing, the burrs are easily ground into grooves by the high-speed moving fibers during normal operation, and then the fibers are scratched, resulting in a decrease in spinning quality. It also avoids the cumbersome operation of frequently maintaining the tooth tip positions. On the other hand, after the polished rack is assembled into card clothing, the overall positive working angle edge is smoother and is not easily worn or cut off under the condition of high fiber rotation speed, and the overall carding effect is better, reducing the influence of the card clothing on the carding effect.

[0029] In an embodiment of the present invention, an automatic wax feeding device is further provided below the circulating polishing track in step S3. The automatic wax feeding device applies polishing wax to the upper and lower surfaces of the rack. The polishing wheel located below the circulating polishing track polishes the upper and lower surfaces of the rack again so that the polishing wax can be evenly applied to the upper and lower surfaces of the rack. There is also an optional step S6.5 between step S6 and step S7, that is, a high-pressure water supply device is used to pump out the wax-removing aqueous solution to wash the upper and lower surfaces of the rack to remove the polishing wax on the upper and lower surfaces of the rack. The application of the polishing wax plays a role in protecting the surface of the rack, and also makes the surface of the rack smoother, flatter and mirror-like after polishing, and the overall rack is also mirror-like, with higher spinning quality and spinning reliability.

[0030] In a preferred embodiment of the present invention, there is also an optional step S1.5 between step S1 and step S2, that is, the residual phosphoric acid solution on the surface of the rack after chemical immersion in step 1 is blown off, removed and collected in the first pretreatment chamber by a high-pressure air outlet device. There is also an optional step S2.5 between step S2 and step S3, that is, the residual phosphorus-containing solution on the surface of the rack after the cleaning treatment in step 2 is blown off, removed and collected in the second pretreatment chamber by a high-pressure air outlet device. It also includes step S9, that is, collecting the phosphorus-containing solution and phosphorus-containing sewage that cannot normally perform the surface treatment of the rack after long-term treatment in step S1, step S1.5, step S2 and step S2.5 and performing dephosphorization treatment, and adding a flocculant or oxidant to the phosphorus-containing solution for chemical dephosphorization of the phosphorus-containing solution and phosphorus-containing sewage. The addition of the optional steps S1.5 and S2.5 effectively reduces the phosphorus content on the surface of the rack during the processing, reduces the influence of phosphoric acid on the rack itself after soaking in the phosphoric acid solution, reduces the influence of the phosphorus-containing solution on the material properties of the rack itself, and also facilitates the subsequent collection of the phosphorus-containing sewage. And in step S9, the phosphorus-containing sewage generated during the overall processing is collected and subjected to dephosphorization and harmless treatment to avoid the adverse impact of the discharge of the phosphorus-containing sewage on the ecological environment. Compared with some existing polishing technologies, it is relatively more environmentally friendly and has less impact on the ecological environment.

[0031] Although the present invention has been disclosed above in specific embodiments, it is not intended to limit the present invention. Any person skilled in the art can still make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope defined in the appended claims.
