Description

Technical Field

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

[0002] An antistatic fiber fabric is a fabric processed through special treatment, which can effectively prevent the generation and accumulation of static electricity. This kind of fabric is widely used in industries sensitive to static electricity, such as the petroleum industry, mining and metallurgy industry, chemical industry, electronics industry, medical treatment, pharmaceutical, food, precision instruments, aerospace, etc.

[0003] According to the production method of an antistatic animal and plant fiber blended fabric disclosed in the publication (announcement) number CN108316021A, with the publication (announcement) date of July 24, 2018, the method includes the following steps: a. Weaving: Blending and weaving camel hair fiber, tussah silk fiber, pineapple leaf fiber and seaweed fiber into a fabric, and the thickness of the fabric is 0.6 - 0.9 mm; b. Preparing an antistatic liquid: Adding 20 - 30 parts by weight of polyvinyl chloride resin, 1.5 - 3.5 parts by weight of azodicarbonamide, 2 - 4 parts by weight of talcum powder, 1.2 - 2.8 parts by weight of white oil, 15 - 20 parts by weight of antistatic agent and 0.5 - 1.5 parts by weight of plasticizer into a mixer together, and the stirring time is 10 - 20 min to obtain the antistatic liquid; c. Coating: Coating the antistatic liquid on the surface of the fabric through a coating device, and the coating speed is 18 - 36 m / min; d. Drying: Putting the coated fabric into an oven for drying, the drying temperature is 80 - 90 °C, and the drying time is 16 - 22 min; e. Washing: Putting the dried fabric into a washing machine for washing, the washing temperature is 25 - 35 °C, and the washing time is 8 - 12 min; f. Air-drying: Naturally air-drying the washed fabric to obtain the antistatic animal and plant fiber blended fabric. Through steps such as weaving, preparing the antistatic liquid, coating, drying, washing and air-drying, the production of the fabric can be realized, and animal fibers and plant fibers are combined together. At the same time, this fabric also has good antistatic performance and is easy to produce.

[0004] In the prior art including the above patents, there are generally two production methods for antistatic fiber cotton. One is to mix conductive wires during the weaving of the fabric, and conduct static electricity through the conductive wires to avoid static electricity accumulation. The other is to coat both sides of the fabric after the fabric weaving is completed, and prevent the generation of static electricity through the coating on the fabric. When using the second method to produce the fabric, usually the fabric is first coated with sizing on both sides, and then the sizing is dried to fix the sizing on the fabric to form a coating. However, when the sizing is scraped on the bottom surface of the fabric in the horizontal direction, usually a scraper or a roller is used to apply the sizing on the bottom surface of the fabric. But in this way, the contact time between the scraper or the roller and the fabric is very short, which results in that the sizing cannot penetrate well between the fibers of the fabric, and thus the connection between the dried coating and the fabric is not tight enough, and the coating is easy to fall off from the fabric. Summary of the Invention

[0005] The purpose of the present invention is to provide a preparation process and a preparation device for an antistatic fiber fabric, aiming to solve the above problems.

[0038] In order to enable those skilled in the art to better understand the technical solutions 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 includes the following steps:

[0041] S1. The cloth body 2 moves in the frame 1 and closely adheres 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 presses 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 hot air is sprayed out from the air outlet 132 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. Then, the slurry is scraped and coated on the cloth body 2 and dried again to obtain the antistatic fiber fabric.

[0046] Embodiment 2

[0047] As shown Figures 1-10 in the figure, a preparation device for an antistatic fiber fabric, which is used to implement the preparation process of the antistatic fiber fabric in the first embodiment, further includes a frame 1, and the frame 1 is provided with:

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

[0049] a plurality of feeding units, each feeding unit includes a housing 11 movably installed on the frame 1, the housing 11 is provided with a movable belt 115 and a support block 111 for supporting the movable belt 115. Along the moving direction of the cloth body 2, a first inclined surface 112, a second inclined surface 113 and a top surface 114 are sequentially arranged on the top of the support block 111. The movable belt 115 is attached to the support block 111 and is movably provided with a plurality of movable pieces 117 for pushing the slurry. Among them:

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

[0051] Specifically, the slope of the first inclined surface 112 is greater than that of the second inclined surface 113. The movable piece 117 is hinged to the movable belt 115, and a groove adapted to the movable piece 117 is formed on the movable belt 115.

[0052] Further, when working, the movable belt 115 drives the movable pieces 117 to move 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 piece 117 relative to the movable belt 115 decreases. When on the first inclined surface 112, the included angle between the movable piece 117 and the movable belt 115 is the largest. When the movable piece 117 moves with the movable belt 115, it will push a part of the slurry in the housing 11 upward. The slurry gradually moves to the second inclined surface 113. At this time, the movable piece 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 piece 117 moves with the movable belt 115. The slurry in the semi-closed chamber is squeezed and gradually penetrates into the fibers of the cloth body 2. Then the movable piece 117 rotates relative to the movable belt 115, the movable piece 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 moving speed of the movable belt 115 on the support block 111 is the same as that of the cloth body 2. The support block 111 cooperates with the movable belt 115 thereon to give the cloth body 2 continuous pressure and supporting force, 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, so that the slurry after drying can firmly adhere to the bottom surface of the cloth body 2. And a plurality of feeding units work sequentially, so that the adhesion between the slurry and the cloth body 2 is strengthened multiple times, and the slurry firmly adheres to the bottom surface of the cloth body 2.

[0053] In the above technical solution, during operation, the cloth body 2 moves in the frame 1 and closely adheres to the bottom surface of the top plate 13. The movable belt 115 drives the movable piece 117 to move 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 piece 117 relative to the movable belt 115 decreases. When on the first inclined surface 112, the included angle between the movable piece 117 and the movable belt 115 is the largest. When the movable piece 117 moves with the movable belt 115, it will push a part of the slurry in the housing 11 upward. The slurry gradually moves to the second inclined surface 113. At this time, the movable piece 117, the movable belt 115 on the second inclined surface 113 and the cloth body 2 form a semi-closed chamber. And the movable piece 117 moves with the movable belt 115. The slurry in the semi-closed chamber is squeezed and gradually penetrates into the fibers of the cloth body 2. Then the movable piece 117 rotates relative to the movable belt 115, the movable piece 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 moving speed of the movable belt 115 on the support block 111 is the same as that of the cloth body 2. The support block 111 and the movable belt 115 thereon give continuous pressure and supporting 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, so that the dried slurry can firmly adhere to the bottom surface of the cloth body 2. And multiple feeding units work in sequence, so that the adhesion between the slurry and the cloth body 2 is strengthened multiple times, and the slurry firmly adheres to the bottom surface of the cloth body 2.

[0054] As a further embodiment provided by the present invention, the maximum value of the included angle between the movable piece 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. Then the top of the movable piece 117 gradually contacts the cloth body 2. The cloth body 2 gives a downward pressure to the movable piece 117, so that the movable piece 117 rotates relative to the movable belt 115 and gradually retracts into the movable belt 115. When the cloth body 2 passes through the subsequent feeding units, the bottom surface of the cloth body 2 is already attached with relatively firm slurry. This part of the 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. Thus, the slurry at the bottom of the cloth body 2 is also flattened and adheres to the bottom surface of the cloth body 2.

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

[0057] Specifically, after the cloth body 2 passes through the feeding unit, the slurry adheres to the bottom surface of the cloth body 2. The cloth body 2 continues to move onto the lifting unit 12, and 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 obliquely upward hot air, and the hot air heats the slurry obliquely above the cloth body 2, which can better penetrate into the fibers of the cloth body 2 and will not push the slurry to separate from the cloth body 2. The hot air first dries the slurry in the fibers of the cloth body 2 and then dries the slurry below, so that the slurry can firmly adhere to the cloth body 2. Even if the slurry cannot be completely dried, the slurry in the fibers of the cloth body 2 and the slurry closely attached to the cloth body 2 will surely be dried, ensuring the adhesion between the slurry and the cloth body 2 and avoiding the separation of the slurry from the cloth body 2.

[0058] As another embodiment further provided by the present invention, a wavy connecting strip 131 for cooperating with the lifting unit 12 to clamp the cloth body 2 is provided on the top plate 13, and a plurality of flow channels with widths decreasing along the gas flow direction are formed between the connecting strip 131 and the top plate 13.

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

[0060] Furthermore, the connecting strip 131 cooperates with a plurality of lifting units 12 to clamp the cloth body 2, providing a lateral supporting force for the cloth body 2 to avoid wrinkles of the cloth body 2 caused by uneven softening when the cloth body 2 is heated. Moreover, 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, accelerating the curing of the slurry while avoiding wrinkles of the cloth body 2. At the same time, as the hot air flows, the flow channels gradually become narrower, enabling the relatively cooler gas that has already completed the drying work to utilize 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 strips 122 are provided on the lifting unit 12, and the lifting unit 12 moves to a predetermined position to enable the plurality of movable strips 122 to be separated from the cloth body 2 one by one.

[0062] Specifically, the lifting unit 12 includes a mounting shell 121 movably installed on the frame 1, and a plurality of movable strips 122 are provided on the mounting shell 121. The plurality of movable strips 122 and the mounting shell 121 form a plane at the top of the lifting unit 12 to hold 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. The tenon block 125 moves downward along the recess 135, driving the middle movable bar 122 downward. After the paddle 124 on the connecting block 123 of the movable bar 122 moves downward a certain distance and contacts the tab 126 on the adjacent movable bar 122, it drives the adjacent movable bar 122 downward. After the adjacent movable bar 122 moves downward a certain distance, it drives the next movable bar 122 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. Then the tenon block 125 moves upward along the other side of the recess 135 and gradually returns to the guide groove 134. The movable bars 122 move 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 for the next operation.

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

[0071] Specifically, a movable rod 119 is slidably provided in the frame 1. The housings 11 of multiple feeding units are fixedly installed on the movable rod 119. A transverse groove is provided on the movable rod 119. A convex rod 141 extending into the groove on the movable rod 119 is provided on the driving disk 14. Feeding ports 118 distributed in a linear array are provided at the bottom of the housing 11. One-way valves are provided on the feeding ports 118. A storage cavity 15 facing multiple feeding units is provided inside the frame 1.

[0072] Further, when the driving disk 14 rotates, the convex rod 141 on the driving disk 14 pushes the movable rod 119 downward. The movable rod 119 drives the housing 11 downward. The housing 11 presses the slurry in the storage cavity 15, and the slurry passes through the one-way valve of the feeding port 118 and enters the housing 11. The driving disk 14 continues to rotate to make the feeding unit move upward and continue the feeding work.

[0073] As another embodiment further provided by the present invention, a transmission disk 144 that rotates as the conveyor belt 128 moves is provided on the frame 1. The transmission disk 144 rotates a predetermined angle to make the driving disk 14 rotate quickly for one week.

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

[0075] Further, during operation, the driving roller 129 drives the transmission disc 144 and the transmission rod 142 to rotate through the synchronous belt 146. The transmission rod 142 drives the driving rod 116 to rotate through the transmission chain 143. The driving rod 116 drives the movable belt 115 to move. The movable belt 115 drives the movable piece 117 from the right side of the support block 111 (in Figure 7Under the action of gravity, the moving piece 117 moves downward and gradually moves below the support block 111. The moving piece 117 rotates relative to the moving belt 115 under the action of gravity. During the process of moving from right to left, the moving piece 117 will push the slurry at the bottom of the support block 111 to move, and push the slurry above the support block 111. The moving belt 115 drives the moving piece 117 to continue moving along the first inclined surface 112, the second inclined surface 113 and the top surface 114 of the support block 111. Moreover, the inclination angle of the moving piece 117 relative to the moving belt 115 decreases. When on the first inclined surface 112, the included angle between the moving piece 117 and the moving belt 115 is the largest. When the moving piece 117 moves with the moving belt 115, it will push a part of the slurry in the housing 11 to move upward, and the slurry gradually moves onto the second inclined surface 113. At this time, the moving piece 117 cooperates with the moving belt 115 on the second inclined surface 113 and the cloth body 2 to form a semi-closed chamber. And the moving piece 117 moves with the moving belt 115, and the slurry in the semi-closed chamber is squeezed and gradually penetrates into the fibers of the cloth body 2. When a moving piece 117 of the first feeding unit moves with the moving belt 115 to the second inclined surface 113 of the support block 111, the distance between the moving piece 117 and the cloth body 2 gradually decreases. Then the top of the moving piece 117 gradually contacts the cloth body 2, and the cloth body 2 gives the moving piece 117 a downward pressure, so that the moving piece 117 rotates relative to the moving belt 115 and gradually retracts into the moving belt 115. When the cloth body 2 passes through the subsequent feeding units, the bottom surface of the cloth body 2 has already adhered to relatively firm slurry, and this part of the slurry will push the moving piece 117 to rotate at a larger angle until the moving piece 117 is embedded in the groove on the moving belt 115. Thus, the slurry at the bottom of the cloth body 2 is also flattened and adhered to the bottom surface of the cloth body 2. The moving piece 117 moves with the moving belt 115 to the top surface 114 of the support block 111. At this time, the moving speed of the moving belt 115 on the support block 111 is the same as that of the cloth body 2. The support block 111 cooperates with the moving belt 115 thereon to give the cloth body 2 continuous pressure and support force, 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 fabric body 2 passes through the feeding unit, the slurry adheres to the bottom surface of the fabric body 2. The fabric body 2 continues to move onto the lifting unit 12. The driving roller 129 drives the conveyor belt 128 to move synchronously with the fabric body 2. The lifting unit 12 holds the fabric and moves synchronously with the fabric. The tenon block 125 moves along the guide groove 134. At this time, the air outlet 132 on the top plate 13 sprays obliquely upward hot air. The hot air heats the slurry obliquely above the fabric body 2, which can better penetrate into the fibers of the fabric body 2 and will not push the slurry to separate from the fabric body 2. The hot air first dries the slurry in the fibers of the fabric body 2 and then dries the slurry below, so that the slurry can firmly adhere to the fabric body 2. Even if the slurry cannot be completely dried, the slurry in the fibers of the fabric body 2 and the slurry closely attached to the fabric body 2 must be dried, ensuring the adhesion between the slurry and the fabric body 2, avoiding the separation of the slurry from the fabric body 2. And the connecting strip 131 cooperates with multiple lifting units 12 to clamp the fabric body 2, providing a lateral supporting force for the fabric body 2 to avoid wrinkles of the fabric body 2 caused by uneven softening when the fabric body 2 is heated. Moreover, the heating plate inside the connecting strip 131 heats the connecting strip 131, so that the connecting strip 131 irons the fabric body 2 and dries the slurry on the fabric body 2, accelerating the curing of the slurry while avoiding wrinkles of the fabric body 2. At the same time, the flow channel gradually narrows during the flow of the hot air, enabling the relatively cooler gas that has already completed the drying work to utilize its residual heat to fully heat the fabric body 2 at the end of the flow channel. After the slurry on the fabric body 2 is dried, the tenon block 125 moves along the guide groove 134 to the recess 135 of the guide groove 134. The tenon block 125 moves downward along the recess 135, driving the movable strip 122 in the middle downward. The flap 124 on the connecting block 123 of the movable strip 122 moves downward a certain distance and then contacts the lug 126 on the adjacent movable strip 122, driving the adjacent movable strip 122 downward. After the adjacent movable strip 122 moves downward a certain distance, it drives the next movable strip 122 downward, gradually reducing the contact area between the lifting unit 12 and the fabric body 2. The tenon block 125 continues to move downward along the recess 135, and multiple movable strips 122 are separated from the fabric body 2. Then the tenon block 125 moves upward along the other side of the recess 135 and gradually returns to the guide groove 134. The movable strips 122 move upward under the action of the spring, and multiple movable strips 122 and the mounting shell 121 form the plane of the lifting unit 12 for the next operation.

[0077] Meanwhile, the drive disc 144 rotates relative to the driving disc 14, and the torsion spring between them accumulates elastic potential energy. When the force transmitted from the drive disc 144 to the movable disc through the torsion spring is sufficient to deform the reed 145, the reed 145 deforms and separates from the frame 1. The torsion spring releases the elastic potential energy to drive the driving disc 14 to quickly rotate one week, thereby driving the feeding unit to reciprocate once. The reed 145 is inserted back into the groove on the frame 1 to lock the driving disc 14. When the movable rod 119 drives the housing 11 to move downward, the drive rod 116 separates from the drive chain 143, and the housing 11 gradually presses the slurry in the storage chamber 15. The slurry passes through the one-way valve at the feed port 118 and enters the housing 11. Then, the movable rod 119 drives the feeding unit to move upward to the highest point, and the drive rod 116 is coupled with the drive chain 143 again to continue the feeding operation. Multiple feeding units cooperate to avoid areas on the bottom surface of the fabric where the slurry is not attached.

Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
