Description

Technical Field

[0001] The invention relates to the technical field of fabric processing, in particular to a device for preparing coatings for highly antistatic fabrics. Background Art

[0002] High antistatic fabrics are processed by spraying, which mainly involves electrostatic spraying process. First, the surface of the fabric needs to be thoroughly cleaned to remove impurities such as oil, dust, etc. to ensure that the coating can be firmly attached to the fabric. Secondly, select a coating with high antistatic properties and prepare the antistatic agent with solvents such as water, ethanol or ethyl acetate into a 0.2%~2% solution. Under the premise of ensuring the antistatic effect, the solution concentration should be as thin as possible to avoid stickiness and easy dust absorption. Use a spray gun to spray the antistatic liquid on the fabric to achieve an effective antistatic effect on the fabric.

[0003] When spraying on the flannel fabric, it is necessary to solve the problem that the antistatic liquid is difficult to penetrate into the inside. In the process of spraying, the fluff of the flannel is easy to adhere to each other in a wet state, which easily leads to local adhesion of the flannel, but the inside of the adhered flannel is still in a dry state. Even if it is sprayed again, it is difficult to separate the adhered flannel. The inside of the flannel is difficult to contact with the antistatic liquid. The antistatic liquid can only be coated on the surface of the flannel. When the above-mentioned spraying is adopted, the fluff of the flannel is subjected to force at the same time, and the state of the flannel fluff is changed. Although the antistatic liquid can penetrate into the inside of the flannel, more antistatic liquid is needed. After the flannel is dried, the concentration of the solution increases, which is easy to cause viscosity and easy to absorb dust. Based on this, it is necessary to coat the inside of the flannel with antistatic liquid, and at the same time, it is necessary to avoid the concentration state of the antistatic liquid solution to avoid the antistatic liquid being viscous and easy to absorb dust after the flannel is dried. Summary of the invention

[0004] The object of the present invention is to provide a device for preparing coatings on highly antistatic fabrics to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, a motor is installed inside the machine body, the shaft roller is rotatably installed inside the end cover, and a transmission belt is transmitted between the outer end of the shaft roller and the motor.

[0009] Furthermore, the air outlet part includes limit strips in a group of two, and the two limit strips in a group are symmetrically arranged, and the two limit strips are respectively located on both sides of the atomizing head, and the two limit strips are slidably clamped on the outer side of the shaft roller. An air outlet cavity is provided between the two limit strips, and the air outlet cavity gradually narrows from the inside to the outside, and the outer end of the air outlet cavity faces the fabric, and the gas moving outward from the air outlet cavity is mixed with the antistatic liquid sprayed from the atomizing head.

[0010] Furthermore, an air delivery cavity is provided at one end of the shaft roller, and the air delivery cavity is communicated with the air outlet cavity. End rings are fixed to the ends of the plurality of groups of limit strips, and the end rings are fixed to the ends of the shaft roller. A cover plate is provided on the outside of the air delivery cavity, and the cover plate is rotatably installed in the end ring. An air delivery hole is provided on the outside of the cover plate for delivering air to the air outlet cavity.

[0011] An infusion hole is provided at the end of the shaft roller, and the infusion hole coincides with the axis of the cover plate. The gas infusion hole and the infusion hole both penetrate the end cover and extend to the outside.

[0012] Furthermore, the transmission frame is composed of two groups of circular frames, which are coaxial with the shaft rollers. A plurality of support rods distributed in a circle are fixed on the inner side of the transmission frame. The fabric extends in an "S" shape along the plurality of support rods, with one side of the fabric fluff facing the shaft roller. Two transmission shafts are also fixed in the transmission frame, and the transmission shafts are used to support the fabric.

[0013] Furthermore, the fabric supported by the multiple groups of support rods is in a polygonal shape, and the fabric between two adjacent support rods extends in a straight shape.

[0019] 3. The fabric on the transmission rack is polygonal in shape, which to a certain extent avoids the arc shape of the fabric, which causes the fluff to be too close to each other, resulting in insufficient separation between the fluff of the fabric and difficulty in completely coating the fabric.

[0020] 4. The fabric is transmitted from multiple groups of post-processing units, and the fluff surface of the fabric contacts the brush. The fluff surface of the fabric is concave in an arc shape, and the gap between the fluffs is closer. When combing, the antistatic liquid on the fluff can be further mixed effectively. The partition bar contacts the back of the fabric fluff, and the fluff surface of the fabric is convex in an arc shape, so that the fluff of the fabric is relatively dispersed and the fluff of the fabric opens and closes. Under the action of the brush, the antistatic liquid and the fluff can be mixed more evenly to a certain extent, and it is also easy to dry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 10 The present invention provides a technical solution: antistatic liquid is sprayed on the fabric using a spray gun to achieve an effective antistatic effect on the fabric. However, when the antistatic liquid is applied, the fluff of the flannel is easily adhered to each other in a wet state, and the inside of the adhered flannel is still in a dry state, and the inside of the flannel is difficult to contact with the antistatic liquid. The antistatic liquid can only be applied on the surface of the flannel. Based on the fact that static electricity is easily generated in the fluff state of the fabric, and the fluff of the fabric is difficult to be coated with the antistatic liquid, a high antistatic fabric coating preparation device is proposed, including a body 1, an end cover 2 is fixed on the upper end of the body 1, a rotatable coating part 4 is installed inside the end cover 2, a transmission frame 5 is sleeved on the outer side of the coating part 4, the transmission frame 5 is used to transmit the fabric, the fabric on the transmission frame 5 is in an arc shape, and it surrounds the outer side of the coating part 4, the fabric is transmitted on the transmission frame 5, and the antistatic liquid is coated on the fabric by the rotation of the coating part 4;

[0035] like Figure 6As shown, the coating part 4 includes a rotatable shaft roller 41, the interior of the shaft roller 41 contains antistatic liquid, an atomizing head 42 is installed on the outer side of the shaft roller 41, and an air outlet is also provided on the outer side of the shaft roller 41, the air outlet is used to disperse the fluff on the fabric, the atomizing head 42 atomizes the antistatic liquid, and as the gas of the air outlet moves outward, a thrust is generated on the fabric, so that the fluff on the fabric is dispersed at the position where the wind blows, and the antistatic liquid can enter deep into the fabric;

[0036] Among them, Figure 6 As shown, the atomizing head 42 is located inside the air outlet, and the antistatic liquid is sprayed on the dispersed part of the fabric fluff, so that the mist generated by the atomizing head 42 moves with the gas.

[0037] like Fig. 9 As shown, a motor is installed inside the machine body 1, and a shaft roller 41 is rotatably installed in the end cover 2. A transmission belt 6 is transmitted between the outer end of the shaft roller 41 and the motor to drive the shaft roller 41 to rotate.

[0038] like Figure 6 As shown, the air outlet portion includes two limiting strips 43 in a group, and the two limiting strips 43 in a group are symmetrically arranged. The two limiting strips 43 are respectively located on both sides of the atomizing head 42, and the two limiting strips 43 are slidably clamped on the outer side of the shaft roller 41. An air outlet cavity 44 is provided between the two limiting strips 43, and the air outlet cavity 44 gradually narrows from the inside to the outside. The outer end of the air outlet cavity 44 faces the fabric, and the gas moving outward from the air outlet cavity 44 is mixed with the antistatic liquid sprayed from the atomizing head 42, so that the gas in the air outlet cavity 44 can move outward and bring the generated mist outward, pushing the fluff of the fabric outward to disperse the fluff. Since the air outlet cavity 44 gradually narrows from the inside to the outside and is in the shape of a strip, the gas moving outward is in the shape of a strip, and the fluff of the fabric is dispersed in the shape of a strip.

[0039] like Figure 7 As shown, an air delivery cavity 46 is provided at one end of the shaft roller 41, and the air delivery cavity 46 is connected with the air outlet cavity 44. An end ring 45 is fixed to the end of the plurality of limit strips 43, and the end ring 45 is fixed to the end of the shaft roller 41. A cover plate 47 is provided on the outer side of the air delivery cavity 46, and the cover plate 47 is rotatably installed in the end ring 45. An air delivery hole 48 is provided on the outer side of the cover plate 47 for delivering air to the air outlet cavity 44. It should be noted that when the shaft roller 41 rotates, the outer cover plate 47 will not rotate, and when air is delivered inward from the air delivery hole 48 on the cover plate 47, the gas can enter the air delivery cavity 46, and the gas is delivered to the air outlet cavity 44, so as to keep blowing the gas outward continuously.

[0040] The end of the shaft roller 41 is provided with an infusion hole 49 , which coincides with the axis of the cover plate 47 . The air infusion hole 48 and the infusion hole 49 both extend through the end cover 2 to the outside, and the antistatic liquid is infused from the infusion hole 49 .

[0041] like Figure 5 As shown, the transmission frame 5 is composed of two groups of circular frames, which are coaxial with the shaft roller 41. A plurality of support rods 52 distributed in a circle are fixed on the inner side of the transmission frame 5. The fabric extends in an "S" shape along the plurality of support rods 52, with the side of the fabric fluff facing the shaft roller 41. Two transmission shafts 51 are also fixed in the transmission frame 5. The transmission shafts 51 are used to support the fabric, and the plurality of support rods 52 are used to limit the fabric so that the fabric presents an arc shape. The two transmission shafts 51 are used to support the fabric and also to change the direction of fabric transmission so that the fabric can enter from one side of the machine body 1 and come out from the other side.

[0042] The fabric supported by multiple groups of support rods 52 is polygonal in shape, making the fabric appear in multiple straight lines. The fabric extends straight between two adjacent support rods 52, which can to a certain extent avoid the fabric from being in an arc shape, causing the fluff to fit too closely, resulting in insufficient separation between the fluff on the fabric and difficulty in completely coating the fabric.

[0043] like Figure 2 As shown, a mounting frame 3 is also fixed inside the end cover 2, and a transmission frame 5 is fixed on the mounting frame 3. A plurality of post-processing units 7 are also installed on the mounting frame 3. The plurality of post-processing units 7 are meshed with each other through gears. The fabrics on each group of post-processing units 7 extend in an "S" shape. The post-processing units 7 are used to comb the fabrics. A transmission belt 6 is also transmitted between the post-processing unit 7 at the end and the shaft roller 41 to transmit the fabrics from the plurality of post-processing units 7 to process the fabrics.

[0044] like Fig.10 As shown, the post-processing unit 7 includes a rotatable transmission roller 1 71 and a transmission roller 2 72. The transmission roller 1 71 has bristles 711 on the outside, and the transmission roller 2 72 has a partition bar 721 on the outside. The fluff side of the fabric being transmitted faces the bristles 711. The transmission roller 1 71 and the transmission roller 2 72 are engaged by gears. The partition bar 721 contacts the back side of the fabric fluff, so that the fluff surface of the fabric is convex in an arc shape, so that the fluff of the fabric is relatively dispersed, and under the condition of external heating, the fluff of the fabric is easy to dry. The fluff surface of the fabric is in contact with the bristles 711, and the fluff surface of the fabric is concave in an arc shape, so that the fabric is combed by the bristles 711 in a large range, so that the fabric is easier to dry, and the direction of the fluff is consistent to avoid being scattered.

[0045] The working principle of the present invention is as follows: the motor can drive the shaft roller 41 to rotate, and the air outlet portion outside the shaft roller 41 also rotates, and in addition, gas is input from the gas delivery hole 48, and antistatic liquid is input from the liquid delivery hole 49. The antistatic liquid moves outward from the atomizing head 42 and moves into the air outlet cavity 44. The gas in the air outlet cavity 44 moves outward along with the atomized antistatic liquid, and moves toward the fabric on the transmission frame 5, so that the antistatic liquid is coated on the fabric;

[0046] It should be noted that after the atomizing head 42 atomizes the antistatic liquid, although it can also produce long-distance transportation, the pushing force on the fabric fluff is limited and cannot penetrate deep into the fabric fluff. As the air outlet cavity 44 transports the gas outward, the relative positions of the fabric fluff can be effectively blown away, so that the fabric fluff is separated to both sides of a group of limiting strips 43. Then, the atomized antistatic liquid enters the position where the fluff is separated, and the entire fluff at the separation is in contact with the atomized antistatic liquid. During the rotation of the shaft roller 41 and the transmission of the fabric, the position where the fabric fluff is separated is moved, and the entire piece of fabric is coated with the antistatic liquid to prevent the fabric fluff from falling off under the action of external combing force, and to prevent the fabric fluff from being coated with excessive antistatic liquid and causing adhesion.

[0047] Secondly, if Figure 8 As shown, the fabric is mounted on the transmission frame 5 and distributed in a circular shape along the shaft roller 41, which can increase the position where the fabric is sprayed and reduce the volume relatively, which is conducive to full utilization of space. In addition, the rotating shaft roller 41 can apply the antistatic liquid more evenly and multiple times.

[0048] The fabric mounted on the transmission frame 5 is polygonal in shape, so that the fabric presents multiple straight lines, which can to a certain extent avoid the fabric being in an arc shape and causing the fluff to fit too closely, resulting in insufficient separation between the fluff on the fabric and difficulty in completely coating the fabric.

[0049] The coated fabric is transferred from multiple groups of post-processing units 7, and the fabric fluff surface is in contact with the brush 711, so that the fabric is combed by the brush 711. At the same time, the fluff surface of the fabric is concave in an arc shape, so that the gap between the fluff is closer, and the antistatic liquid on the fluff can be effectively mixed during combing. The partition strip 721 is in contact with the back of the fabric fluff, so that the fabric fluff surface is convex in an arc shape, so that the fluff of the fabric is relatively dispersed, and the fabric fluff opens and closes. Under the action of the brush 711, the antistatic liquid and the fluff can be mixed more evenly to a certain extent, and it is also easy to dry.
