Description

Technical Field

[0001] The invention relates to the technical field of fiber fabric preparation, and in particular to a preparation process and a preparation device for an antistatic fiber fabric. Background Art

[0002] Antistatic fiber fabric is a specially processed fabric that can effectively prevent the generation and accumulation of static electricity. This fabric is widely used in industries that are sensitive to static electricity, such as the petroleum industry, mining and metallurgy industry, chemical industry, electronics industry, medical treatment, pharmaceuticals, food, precision instruments, aerospace, etc.

[0003] According to the publication (announcement) number CN108316021A, the publication (announcement) date is 2018-07-24, and a production method of an antistatic animal and plant fiber blended fabric is disclosed, comprising the following steps: a. weaving: blending camel hair fiber, tussah silk fiber, pineapple leaf fiber and seaweed fiber into a fabric, the thickness of the fabric is 0.6-0.9mm; b. preparing an antistatic liquid: by weight, 20-30 parts of polyvinyl chloride resin, 1.5-3.5 parts of azodicarbonamide, 2-4 parts of talcum powder, 1.2-2.8 parts of white oil, 15-20 parts of antistatic agent and 0.5 parts of plasticizer are mixed. -1.5 parts are added to the mixer, and the stirring time is 10-20 minutes to obtain the antistatic liquid; c. coating: the antistatic liquid is coated on the surface of the fabric through the coating device, and the coating speed is 18-36m / min; d. drying: the coated fabric is placed in an oven for drying, the drying temperature is 80-90℃, and the drying time is 16-22min; e. washing: the dried fabric is placed in a washing machine for washing, the washing temperature is 25-35℃, and the washing time is 8-12min; f. drying: the washed fabric is naturally dried to obtain the antistatic animal and plant fiber blended fabric. The method realizes the production of fabrics through the steps of weaving, preparing antistatic liquid, coating, drying, washing and drying, and combines animal fibers and plant fibers together. At the same time, the fabric also has good antistatic properties and is easy to produce.

[0004] In the prior art including the above patents, there are generally two ways to produce antistatic fiber cotton. One is to mix conductive threads into the fabric when weaving it, conduct static electricity through the conductive threads, and avoid static electricity accumulation. The other is to apply a coating to both sides of the fabric after the fabric is woven, and prevent static electricity generation through the coating on the fabric. When using the second method to produce fabric, the fabric is usually first coated with slurry on both sides, and then the slurry is dried to fix the slurry on the fabric to form a coating. However, when the bottom surface of the fabric is horizontally coated with slurry, the slurry is usually applied to the bottom surface of the fabric with a scraper or roller. However, the contact time between the scraper or roller and the fabric in this way is very short, which results in the slurry not being able to penetrate well into the fibers of the fabric, which also results in the coating after drying being not tightly connected to the fabric, and the coating is easy to fall off the fabric.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Embodiment 1

[0040] A preparation process of an antistatic fiber fabric comprises the following steps:

[0041] S1, the cloth body 2 moves in the frame 1 and is close to the bottom of the top plate 13;

[0042] S2, the feeding unit applies the slurry to the bottom of the cloth body 2 and the top surface 114 of the support block 111 continuously squeezes the slurry, so that the slurry is fixed on the bottom surface of the cloth body 2 and penetrates into the fibers of the cloth body 2;

[0043] S3, the lifting unit 12 cooperates with the top plate 13 to clamp the cloth body 2, and the air outlet 132 sprays hot air to dry the slurry;

[0044] S4, the slurry solidifies on the cloth body 2, and the lifting unit 12 is separated from the cloth body 2;

[0045] S5, scraping and coating the slurry on the cloth body 2, and drying it again to obtain the antistatic fiber fabric.

[0046] Embodiment 2

[0047] like Figure 1-10 As shown, a device for preparing an antistatic fiber fabric, which is used to implement the preparation process of the antistatic fiber fabric in Example 1, also includes a frame 1, on which the following components are arranged:

[0048] A top plate 13, which abuts against the top of the cloth body 2;

[0049] Multiple feeding units, the feeding units include a shell 11 movably mounted on the frame 1, a movable belt 115 and a support block 111 for supporting the movable belt 115 are provided on the shell 11, a first inclined surface 112, a second inclined surface 113 and a top surface 114 are sequentially provided on the top of the support block 111 along the moving direction of the cloth body 2, the movable belt 115 is attached to the support block 111 and is movably provided with a plurality of movable sheets 117 for pushing the slurry, wherein:

[0050] The movable belt 115 moves so that the movable piece 117 moves along the first inclined surface 112 , the second inclined surface 113 and the top surface 114 of the support block 111 in sequence, and the inclination angle of the movable piece 117 relative to the movable belt 115 decreases gradually.

[0051] Specifically, the slope of the first inclined surface 112 is greater than the slope of the second inclined surface 113 . The movable sheet 117 is hinged to the movable belt 115 . The movable belt 115 is provided with a groove adapted to the movable sheet 117 .

[0052] Furthermore, when working, the movable belt 115 moves with the movable sheet 117 along the first inclined surface 112, the second inclined surface 113 and the top surface 114 of the top of the support block 111, and the inclination angle of the movable sheet 117 relative to the movable belt 115 decreases gradually. When on the first inclined surface 112, the angle between the movable sheet 117 and the movable belt 115 is the largest. When the movable sheet 117 moves with the movable belt 115, it will push part of the slurry in the shell 11 to move upward, and the slurry gradually moves to the second inclined surface 113. At this time, the movable sheet 117 cooperates with the movable belt 115 on the second inclined surface 113 and the cloth body 2 to form a semi-enclosed chamber, and the movable sheet 117 moves with the movable belt 115, and the slurry in the semi-enclosed chamber is The movable sheet 117 is then rotated relative to the movable belt 115, and the movable sheet 117 is embedded in the movable belt 115 and moves with the movable belt 115 to the top surface 114 of the support block 111. At this time, the movable belt 115 on the support block 111 has the same moving speed as the cloth 2. The support block 111 cooperates with the movable belt 115 thereon to give continuous pressure and support to the cloth 2, so that the slurry on the cloth 2 can adhere to the bottom surface of the cloth 2 and infiltrate into the fibers of the cloth 2, so that the dried slurry can be firmly attached to the bottom surface of the cloth 2, and multiple feeding units work in sequence, so that the adhesion between the slurry and the cloth 2 is strengthened many times, so that the slurry is firmly attached to the bottom surface of the cloth 2.

[0053] In the above technical solution, when working, the cloth body 2 moves in the frame 1 and is close to the bottom surface of the top plate 13, and the movable belt 115 moves with the movable sheet 117 along the first inclined surface 112, the second inclined surface 113 and the top surface 114 of the top of the support block 111, and the inclination angle of the movable sheet 117 relative to the movable belt 115 decreases gradually. When on the first inclined surface 112, the angle between the movable sheet 117 and the movable belt 115 is the largest. When the movable sheet 117 moves with the movable belt 115, it will push part of the slurry in the shell 11 to move upward, and the slurry gradually moves to the second inclined surface 113. At this time, the movable sheet 117 cooperates with the movable belt 115 on the second inclined surface 113 and the cloth body 2 to form a semi-closed chamber, and the movable sheet 117 moves with the movable belt 115. The movable sheet 117 rotates relative to the movable belt 115, and the movable sheet 117 is embedded in the movable belt 115 and moves with the movable belt 115 to the top surface 114 of the support block 111. At this time, the movable belt 115 on the support block 111 has the same moving speed as the cloth 2. The support block 111 cooperates with the movable belt 115 thereon to give continuous pressure and support force to the cloth 2, so that the slurry on the cloth 2 can adhere to the bottom surface of the cloth 2 and infiltrate into the fibers of the cloth 2, so that the dried slurry can be firmly attached to the bottom surface of the cloth 2, and multiple feeding units work in sequence, so that the adhesion between the slurry and the cloth 2 is strengthened many times, so that the slurry is firmly attached to the bottom surface of the cloth 2.

[0054] As a further embodiment of the present invention, the maximum value of the angle between the movable sheet 117 and the movable belt 115 is an acute angle.

[0055] Specifically, when a movable piece 117 of the first feeding unit moves with the movable belt 115 to the second inclined surface 113 of the support block 111, the distance between the movable piece 117 and the cloth body 2 gradually decreases, and then the top of the movable piece 117 gradually contacts the cloth body 2, and the cloth body 2 applies a downward pressure to the movable piece 117, so that the movable piece 117 rotates relative to the movable belt 115 and gradually shrinks into the movable belt 115. When the cloth body 2 passes through the subsequent feeding unit, the bottom surface of the cloth body 2 is already adhered to with relatively firm slurry, and this part of slurry will push the movable piece 117 to rotate a larger angle until the movable piece 117 is embedded in the groove on the movable belt 115, and the slurry at the bottom of the cloth body 2 is also flattened and adhered to the bottom surface of the cloth body 2.

[0056] As another embodiment further provided by the present invention, the frame 1 is provided with a plurality of lifting units 12 for lifting the cloth body 2 and having the same moving speed as the cloth body 2, and the top plate 13 is provided with an air outlet 132 which is inclined to cooperate with the lifting units 12 and allows hot air to pass through.

[0057] Specifically, after the cloth 2 passes through the loading unit, the slurry adheres to the bottom surface of the cloth 2, and the cloth 2 continues to move to the lifting unit 12. The lifting unit 12 holds the cloth and moves synchronously with the cloth. At this time, the air outlet 132 on the top plate 13 sprays oblique hot air, and the hot air heats the slurry from the oblique upper part of the cloth 2, which can better penetrate into the fibers of the cloth 2 and will not push the slurry to separate from the cloth 2. The hot air first dries the slurry in the fibers of the cloth 2 and then dries the slurry below, so that the slurry can be firmly attached to the cloth 2. Even if the slurry cannot be completely dried, the slurry in the fibers of the cloth 2 and close to the cloth 2 can definitely be dried, thereby ensuring the adhesion between the slurry and the cloth 2 and avoiding the separation of the slurry from the cloth 2.

[0058] As another embodiment further provided by the present invention, a wavy connecting strip 131 is provided on the top plate 13 to cooperate with the lifting unit 12 to clamp the cloth body 2, and the connecting strip 131 and the top plate 13 form a plurality of flow channels whose width decreases along the gas flow direction.

[0059] Specifically, an exhaust port 133 is provided at the turning portion of the connecting strip 131 , and a heating plate is provided inside the connecting strip 131 .

[0060] Furthermore, the connecting strip 131 cooperates with the plurality of lifting units 12 to clamp the cloth body 2, providing lateral support force to the cloth body 2, thereby avoiding wrinkles of the cloth body 2 caused by uneven softening when the cloth body 2 is heated, and the heating plate inside the connecting strip 131 heats the connecting strip 131, so that the connecting strip 131 irons the cloth body 2 and dries the slurry on the cloth body 2, thereby avoiding wrinkles of the cloth body 2 and accelerating the solidification of the slurry. At the same time, the flow channel of the hot air gradually narrows during the flow process, so that the gas with a lower temperature that has been dried can exert its residual heat to fully heat the cloth body 2 at the end of the flow channel.

[0061] As another embodiment further provided by the present invention, a plurality of movable bars 122 are provided on the lifting unit 12, and the lifting unit 12 moves to a predetermined position so that the plurality of movable bars 122 are separated from the cloth body 2 one by one.

[0062] Specifically, the lifting unit 12 includes a mounting shell 121 movably mounted on the frame 1 , and a plurality of movable bars 122 are provided on the mounting shell 121 . The plurality of movable bars 122 and the mounting shell 121 form a plane on the top of the lifting unit 12 to lift the cloth body 2 .

[0063] Furthermore, during operation, multiple movable bars 122 cooperate with the mounting shell 121. When the slurry drying work on the cloth body 2 is completed, the lifting unit 12 that moves synchronously with the cloth body 2 also moves to a predetermined position. At this time, multiple movable bars 122 move one by one and separate from the cloth body 2. When one of the movable bars 122 is separated from the cloth body 2, the other movable bars 122 can support the cloth body 2 and the dried slurry coating on the cloth body 2, thereby preventing the slurry from having excessive adhesion to the lifting unit 12 during the drying process, which may cause part of the slurry coating to be torn off from the cloth body 2 when the lifting unit 12 is separated from the cloth body 2 as a whole, thereby ensuring the integrity of the slurry coating on the cloth body 2.

[0064] As another embodiment further provided by the present invention, a conveyor belt 128 for driving the multiple lifting units 12 to move is disposed on the frame 1, and a guide groove 134 for guiding the movement of the movable bar 122 is opened on the frame 1.

[0065] Specifically, a driving roller 129 for driving the conveyor belt 128 to move is provided on the frame 1 , and the mounting shell 121 is fixed on the conveyor belt 128 through a tenon rod 127 .

[0066] Furthermore, during operation, the driving roller 129 drives the conveyor belt 128 to move synchronously with the cloth body 2, thereby causing the lifting unit 12 on the conveyor belt 128 to move synchronously with the cloth body 2. After the slurry on the cloth body 2 is dried, the guide groove 134 on the frame 1 pushes the multiple movable bars 122 on the mounting shell 121 to move one by one, thereby gradually reducing the contact area between the lifting unit 12 and the cloth body 2.

[0067] As another embodiment further provided by the present invention, a tenon block 125 adapted to the guide groove 134 and a paddle 124 for moving the adjacent movable bar 122 downward are provided on one of the middle movable bars 122 , and a recess 135 is provided on the guide groove 134 .

[0068] Specifically, a connecting block 123 is provided on the movable bar 122, a spring is provided between the connecting block 123 and the mounting shell 121, a tenon 125 is provided on the connecting block 123 of the movable bar 122 in the middle of the same lifting unit 12, and a paddle 124 is symmetrically provided on the connecting block 123, and paddles 124 and protrusions 126 are provided on the connecting blocks 123 on the movable bars 122 on both sides (such as Figure 7 shown).

[0069] Further, after the slurry on the cloth body 2 is dried, the tenon block 125 moves along the guide groove 134 to the recess 135 of the guide groove 134, and the tenon block 125 moves downward along the recess 135, driving the movable bar 122 in the middle to move downward. The paddle 124 on the connecting block 123 of the movable bar 122 moves downward for a distance and contacts with the protruding piece 126 on the adjacent movable bar 122, and drives the adjacent movable bar 122 to move downward. After the adjacent movable bar 122 moves downward for a distance, it drives the next movable bar 122 to move downward, thereby gradually reducing the contact area between the lifting unit 12 and the cloth body 2, and the tenon block 125 continues to move downward along the recess 135, and multiple movable bars 122 are separated from the cloth body 2, and then the tenon block 125 moves upward along the other side of the recess 135 and gradually returns to the guide groove 134, and the movable bar 122 moves upward under the action of the spring, and multiple movable bars 122 and the mounting shell 121 form the plane of the lifting unit 12, waiting for the next work.

[0070] As another embodiment further provided by the present invention, a driving disk 14 for driving the loading unit to reciprocate in the vertical direction is rotatably provided on the frame 1, and the loading unit is in a high position to move the movable belt 115 thereon.

[0071] Specifically, a movable rod 119 is slidably provided in the frame 1, and the shells 11 of multiple feeding units are fixedly installed on the movable rod 119. The movable rod 119 is provided with a transverse groove, and the driving disk 14 is provided with a protruding rod 141 extending into the groove on the movable rod 119. The bottom of the shell 11 is provided with feed ports 118 distributed in a linear array, and a one-way valve is provided on the feed port 118. The interior of the frame 1 is provided with a storage cavity 15 facing the multiple feeding units.

[0072] Furthermore, when the driving disk 14 rotates, the protruding rod 141 on the driving disk 14 pushes the movable rod 119 to move downward, and the movable rod 119 drives the shell 11 to move downward. The shell 11 presses the slurry in the storage chamber 15, and the slurry passes through the one-way valve of the feed port 118 and enters the shell 11. The driving disk 14 continues to rotate to move the loading unit upward to continue the loading work.

[0073] As another embodiment further provided by the present invention, a transmission disc 144 is provided on the frame 1 and rotates along with the conveyor belt 128. The transmission disc 144 rotates by a predetermined angle to enable the driving disc 14 to quickly rotate one circle.

[0074] Specifically, a transmission rod 142 is provided on the frame 1, and a synchronous belt 146 is provided between the transmission rod 142, the transmission disk 144 and the driving roller 129. A transmission chain 143 driven by the transmission rod 142 is provided on the frame 1, and a driving rod 116 adapted to the transmission chain 143 and used to drive the movable belt 115 to move is provided in the shell 11, a torsion spring is provided between the transmission disk 144 and the driving disk 14, a spring leaf 145 extending into the frame 1 is provided on the driving disk 14, and a groove adapted to the spring leaf 145 is opened on the frame 1.

[0075] Furthermore, during operation, the driving roller 129 drives the transmission plate 144 and the transmission rod 142 to rotate through the synchronous belt 146, and the transmission rod 142 drives the driving rod 116 to rotate through the transmission chain 143, and the driving rod 116 moves with the movable belt 115, and the movable belt 115 moves with the movable sheet 117 from the right side of the support block 111 (with Figure 7The movable sheet 117 rotates relative to the movable belt 115 under the action of gravity, and the movable sheet 117 pushes the slurry at the bottom of the support block 111 to move when moving from right to left, and pushes the slurry to the top of the support block 111. The movable belt 115 continues to move along the first inclined surface 112, the second inclined surface 113 and the top surface 114 at the top of the support block 111 with the movable sheet 117, and the inclination angle of the movable sheet 117 relative to the movable belt 115 decreases. When the movable sheet 117 is on the first inclined surface 112, the angle between the movable sheet 117 and the movable belt 115 is the largest. When the movable sheet 117 moves with the movable belt 115, it will push part of the slurry in the shell 11 to move upward, and the slurry gradually moves to the second inclined surface 113. At this time, the movable sheet 117 cooperates with the movable belt 115 on the second inclined surface 113 and the cloth body 2 to form a semi-enclosed chamber, and the movable sheet 117 moves with the movable belt 115. The slurry in the semi-enclosed chamber is squeezed and gradually penetrates into the fibers of the cloth body 2. When a movable piece 117 moves with the movable belt 115 to the second inclined surface 113 of the support block 111, the distance between the movable piece 117 and the cloth body 2 gradually decreases, and then the top of the movable piece 117 gradually contacts the cloth body 2. The cloth body 2 gives the movable piece 117 a downward pressure, so that the movable piece 117 rotates relative to the movable belt 115 and gradually shrinks into the movable belt 115. When the cloth body 2 passes through the rear feeding unit, the bottom surface of the cloth body 2 is already attached with a relatively firm slurry, and this part of the slurry will push the movable piece 117. The movable sheet 117 is rotated at a larger angle until it is embedded in the groove on the movable belt 115. At this point, the slurry on the bottom of the cloth body 2 is also flattened and adheres to the bottom surface of the cloth body 2. The movable sheet 117 moves with the movable belt 115 to the top surface 114 of the support block 111. At this time, the movable belt 115 on the support block 111 has the same moving speed as the cloth body 2. The support block 111 cooperates with the movable belt 115 thereon to give continuous pressure and support force to the cloth body 2, so that the slurry on the cloth body 2 can adhere to the bottom surface of the cloth body 2 and infiltrate into the fibers of the cloth body 2.

[0076] After the cloth 2 passes through the feeding unit, the slurry adheres to the bottom surface of the cloth 2, and the cloth 2 continues to move to the lifting unit 12. The driving roller 129 drives the conveyor belt 128 to move synchronously with the cloth 2. The lifting unit 12 holds the cloth and moves synchronously with the cloth. The tenon 125 moves along the guide groove 134. At this time, the air outlet 132 on the top plate 13 sprays oblique hot air. The hot air heats the slurry from the oblique upper part of the cloth 2, which can better penetrate into the fibers of the cloth 2 and will not push the slurry to separate from the cloth 2. The hot air first dries the slurry in the fibers of the cloth 2 and then dries the slurry below, so that the slurry can The slurry can be firmly attached to the cloth 2. Even if the slurry cannot be completely dried, the slurry in the fibers of the cloth 2 and close to the cloth 2 can be dried, which ensures the adhesion between the slurry and the cloth 2 and prevents the slurry from separating from the cloth 2. The connecting strip 131 cooperates with the multiple lifting units 12 to clamp the cloth 2, provide lateral support for the cloth 2, and avoid wrinkles of the cloth 2 caused by uneven softening when the cloth 2 is heated. The heating plate inside the connecting strip 131 heats the connecting strip 131, so that the connecting strip 131 irons the cloth 2 and dries the slurry on the cloth 2, avoiding wrinkles of the cloth 2 while increasing The solidification of the slurry is accelerated, and the flow channel gradually narrows during the flow of hot air, so that the gas with a lower temperature that has been dried can use its residual heat to fully heat the cloth body 2 at the end of the flow channel. After the slurry on the cloth body 2 is dried, the tenon 125 moves along the guide groove 134 to the recess 135 of the guide groove 134, and the tenon 125 moves downward along the recess 135, thereby driving the middle movable bar 122 to move downward. The paddle 124 on the connecting block 123 of the movable bar 122 moves downward for a distance and contacts the convex piece 126 on the adjacent movable bar 122. And drive the adjacent movable bar 122 to move downward, after the adjacent movable bar 122 moves downward for a distance, it drives the next movable bar 122 to move downward, thereby gradually reducing the contact area between the lifting unit 12 and the cloth body 2, the tenon block 125 continues to move downward along the recess 135, and multiple movable bars 122 are separated from the cloth body 2, and then the tenon block 125 moves upward along the other side of the recess 135 and gradually returns to the guide groove 134, and the movable bar 122 moves upward under the action of the spring, and multiple movable bars 122 and the mounting shell 121 form the plane of the lifting unit 12, waiting for the next work.

[0077] At the same time, the transmission disk 144 rotates relative to the driving disk 14, and the torsion spring between the two accumulates elastic potential energy. When the force transmitted to the movable disk by the transmission disk 144 through the torsion spring is sufficient to deform the spring leaf 145, the spring leaf 145 is deformed and separated from the frame 1, and the torsion spring releases the elastic potential energy to drive the driving disk 14 to rotate rapidly for one circle, thereby driving the feeding unit to reciprocate once, and the spring leaf 145 is reinserted into the groove on the frame 1 to lock the driving disk 14. When the movable rod 119 drives the shell 11 to move downward, the driving rod 116 is separated from the transmission chain 143, and the shell 11 gradually presses the slurry in the storage chamber 15. The slurry passes through the one-way valve of the feed port 118 and enters the shell 11. Then the movable rod 119 moves the feeding unit upward to the highest point, and the driving rod 116 is coupled with the transmission chain 143 again to continue the feeding work. Multiple feeding units work together to avoid the appearance of unattached slurry areas on the bottom surface of the cloth.

[0078] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
