Description

Technical Field

[0001] This invention relates to the field of polyester fabric production technology, specifically a production device for polyester cut-resistant and puncture-resistant fabric. Background Technology

[0002] With the increasing demand for safety and protection in modern society, the application fields of high-performance protective fabrics are constantly expanding, especially in the fields of military, outdoor adventure clothing and professional clothing in special working environments, which place higher demands on the cut and puncture resistance of textiles. Polyester, as a widely used synthetic fiber, has become one of the ideal base materials for preparing cut and puncture resistant fabrics due to its excellent abrasion resistance, wrinkle resistance and high strength.

[0003] In the production process of polyester cut- and puncture-resistant fabrics, in order to give the fabric good cut- and puncture-resistant properties, the polyester greige fabric is often immersed in a solution containing cut- and puncture-resistant materials, such as shear thickening liquid. Through immersion, the cut- and puncture-resistant materials are attached to the surface of the fabric and the gaps between the fibers, thereby enhancing the cut- and puncture-resistant properties of the fabric. During the immersion process, the solution penetrates the polyester greige fabric from the outside to the inside. For thicker polyester greige fabrics, the penetration time is long, and multiple immersions may be required, which seriously affects the production efficiency of polyester cut- and puncture-resistant fabrics.

[0004] Therefore, the present invention proposes a production apparatus for polyester cut-resistant and puncture-resistant fabric to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a production apparatus for polyester cut-resistant and puncture-resistant fabric to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A production apparatus for polyester cut- and puncture-resistant fabric includes an impregnation tank. The impregnation tank contains a box-shaped component that can reciprocate along the polyester fabric transport path. When the moving direction of the box-shaped component is the same as the transport direction of the polyester fabric, its moving speed is the same as the transport speed of the polyester fabric. The box-shaped component contains a counterweight seat that can cyclically switch between separation and puncture positions. The counterweight seat has a connecting rod penetrating the bottom side of the box-shaped component. A base plate is provided at the lower end of the connecting rod. Puncture needles for puncturing the polyester fabric are evenly distributed on the base plate. When the moving direction of the box-shaped component is the same as the transport direction of the polyester fabric, the counterweight seat is in the puncture position, i.e., the puncture needles penetrate the polyester fabric. When the moving direction of the box-shaped component is opposite to the transport direction of the polyester fabric, the counterweight seat is in the separation position, i.e., the puncture needles detach from the polyester fabric.

[0007] In one alternative: liquid-passing grooves are uniformly distributed on the substrate.

[0008] In one alternative: the puncture needle body is provided with uniformly spaced recesses.

[0009] In one alternative embodiment: the production apparatus further includes a reciprocating mechanism for realizing the reciprocating movement of the box component. The reciprocating mechanism includes a chute located on one side of the immersion tank, a slide block slidably engaged in the chute, and a driven member located on the chute. The slide block is fixedly connected to the box component. The driven member is provided with a through groove. The immersion tank is provided with a rotatable drive plate and a drive member for driving the drive plate to rotate. The drive member is a variable speed servo motor. The drive plate is provided with a column adapted to the through groove, and the end of the column away from the drive plate passes through the through groove.

[0010] In one alternative: the counterweight base is made of iron material, the box body is provided with a rotatable cylindrical component, the cylindrical component is located above the counterweight base and perpendicular to the counterweight base, a matching magnet is sleeved on the cylindrical component, the radial cross section of the magnet is semi-circular, and the cylindrical component rotates one revolution when the box body completes one reciprocating process. The radial cross-section of the connecting rod is not circular.

[0011] In one alternative: the counterweight seat has a concave surface on the side facing the cylindrical member, and the curvature of the concave surface is consistent with the curvature of the outer side of the magnet.

[0012] In one alternative embodiment: the production apparatus further includes a transmission mechanism for rotating the cylindrical component. The transmission mechanism includes a first driven shaft rotatably disposed in the immersion tank and a second driven shaft rotatably disposed on the housing component. The second driven shaft has a square radial cross-section. The first driven shaft is provided with a slot adapted to the second driven shaft. Part of the shaft end of the second driven shaft is inserted into the slot. The first driven shaft is driven by a first bevel gear set, and the second driven shaft is driven by a second bevel gear set. The transmission ratio of the first bevel gear set and the second bevel gear set is 1.

[0013] In one alternative: the impregnation tank is provided with rows of pressure-receiving components on both sides of the polyester fabric transport path, and the line connecting the two rows of pressure-receiving components is perpendicular to the polyester fabric transport path. Each pressure-receiving component is provided with a spring between itself and the impregnation tank wall, and each pressure-receiving component is provided with a spring bar. The base plate is provided with pressing components on both sides for pressing the two rows of pressure-receiving components respectively.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: Polyester fabric is conveyed through the impregnation tank at a certain speed for impregnation. During the impregnation process, the box component moves back and forth, driving the substrate to move back and forth. When the movement direction of the box component is the same as the conveying direction of the polyester fabric, the counterweight switches from the original separation station to the piercing station. This process enables the piercing needle to pierce the polyester fabric. Then, before the box component returns to its original position, the counterweight switches from the original piercing station to the separation station. This process enables the piercing needle to pierce the polyester fabric. This cycle is repeated to pierce the polyester fabric and form needle holes, allowing the solution containing cut-resistant and puncture-resistant material to penetrate through the needle holes. This achieves simultaneous penetration of the solution inside and outside, effectively shortening the impregnation time of the polyester fabric and thus improving the production efficiency of polyester cut-resistant and puncture-resistant fabric.

Detailed Implementation

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Please see Figures 1-4 A production apparatus for polyester cut- and puncture-resistant fabric includes an impregnation tank 2. The impregnation tank 2 contains a box 3 that can reciprocate along the polyester fabric transport path. When the moving direction of the box 3 is the same as the polyester fabric transport direction, its moving speed is the same as the polyester fabric transport speed. The box 3 contains a counterweight 7 that can cyclically switch between separation and puncture positions. The counterweight 7 has a connecting rod 8 penetrating the bottom side of the box 3. The lower end of the connecting rod 8 has a base plate 9. Puncture needles 10 for puncturing the polyester fabric are evenly distributed on the base plate 9. When the moving direction of the box 3 is the same as the polyester fabric transport direction, the counterweight 7 is in the puncture position, i.e., the puncture needles 10 pass through the polyester fabric. When the moving direction of the box 3 is opposite to the polyester fabric transport direction, the counterweight 7 is in the separation position, i.e., the puncture needles 10 detach from the polyester fabric.

[0029] It should be noted that the puncture needle is thin and leaves a small hole when puncturing the polyester fabric, which will not cause damage. In addition, the subsequent processing of polyester fabric involves a setting process, such as heat setting and wet setting, which can promote the shrinkage of polyester fibers to a certain extent, thereby repairing the needle hole.

[0030] The polyester fabric is conveyed through the impregnation tank 2 at a certain speed for impregnation. During the impregnation process, the housing 3 reciprocates, causing the substrate 9 to reciprocate. When the movement direction of the housing 3 is the same as the conveying direction of the polyester fabric, the counterweight 7 switches from the original separation station to the piercing station. This process enables the piercing needle 10 to pierce the polyester fabric. Then, before the housing 3 returns to its original position (i.e., before the movement direction of the housing 3 switches to the opposite direction to the conveying direction of the polyester fabric), the counterweight 7 switches from the original piercing station to the separation station. This process enables the piercing needle 10 to pierce the polyester fabric. This cycle is repeated to impregnate the polyester fabric. The puncture creates a needle hole, allowing the solution containing the cut- and puncture-resistant material to penetrate inwards through the needle hole, achieving simultaneous penetration from the inside and outside of the solution. This effectively shortens the impregnation time of the polyester fabric and thus improves the production efficiency of the polyester cut- and puncture-resistant fabric. In addition, in this invention, the purpose of the moving speed of the box component 3 when its moving direction is the same as the polyester fabric conveying direction is to keep the process relatively stationary with respect to the polyester fabric, avoiding tearing damage to the fabric when the puncture needle 10 punctures / detaches from the polyester fabric. The reset speed of the box component 3 is not limited, as long as the puncture frequency of the puncture needle 10 can fully cover the polyester fabric.

[0031] Furthermore, liquid channels 17 are uniformly distributed on the substrate 9 to reduce the solution resistance encountered by the substrate 9 when it moves.

[0032] Furthermore, the puncture needle 10 is uniformly provided with recessed holes 18. When the puncture needle 10 punctures / removes from the polyester fabric, the solution in the recessed holes 18 is immediately carried into the needle holes on the polyester fabric, rather than the solution only entering the needle holes when the puncture needle 10 is removed, thereby further improving the impregnation efficiency of the polyester fabric.

[0033] Please see Figure 1 , Figure 5 and Figure 6 In one embodiment of the present invention, the production device further includes a reciprocating mechanism 12 for realizing the reciprocating movement of the housing 3. The reciprocating mechanism 12 includes a slide groove 1201 disposed on one side of the immersion tank 2, a slide block 1202 slidably locked in the slide groove 1201, and a driven member 1203 disposed on the slide groove 1201. The slide block 1202 is fixedly connected to the housing 3. The driven member 1203 is provided with a through groove 1204. The immersion tank 2 is provided with a rotatable drive disk 1205 and a drive member for driving the drive disk 1205 to rotate. The drive member is a variable speed servo motor. The drive disk 1205 is provided with a column 1206 adapted to the through groove 1204, and one end of the column 1206 away from the drive disk 1205 passes through the through groove 1204.

[0034] It should be noted that when the drive disc 1205 rotates and drives the housing 3 to move in the same direction as the polyester fabric transmission direction, the output shaft of the drive component is in a variable speed state, so as to ensure that the housing 3 is in a uniform speed state during the movement process (i.e., consistent with the polyester fabric transmission speed).

[0035] In this embodiment, the drive disk 1205 rotates, and with the cooperation of the column 1206 and the through groove 1204, the drive disk 1205 rotates and drives the slide block 1202 to slide back and forth along the slide groove 1201, thereby driving the housing 3 to move back and forth.

[0036] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the counterweight seat 7 is made of iron material, and the box body 3 is provided with a rotatable cylindrical part 4. The cylindrical part 4 is located above the counterweight seat 7 and is perpendicular to the counterweight seat 7. A suitable magnet 5 is sleeved on the cylindrical part 4. The radial cross section of the magnet 5 is semi-circular. When the box body 3 completes one reciprocating process, the cylindrical part 4 rotates one revolution. The radial cross-section of the connecting rod 8 is non-circular.

[0037] It should be noted that the cylindrical component 4 is made of magnetic shielding material, which is used to block magnetic attraction when the magnet 5 and the counterweight 7 are not opposite each other.

[0038] In this embodiment, the rotation of the cylindrical component 4 drives the rotation of the magnet 5. When the magnet 5 rotates to be opposite the counterweight 7, the counterweight 7 is attracted and comes into contact with the magnet 5 under the action of magnetic attraction, completing the switch from the piercing station to the separation station, thereby driving the piercing needle 10 to detach from the polyester fabric. During the return process of the box component 3, the counterweight 7 is always attracted and in contact with the magnet 5. As the magnet 5 rotates, when the magnet 5 rotates to the point of detaching from the counterweight 7, the counterweight 7 moves down under its own gravity, completing the switch from the separation station to the piercing station, thereby driving the piercing needle 10 to pierce the polyester fabric, and so on.

[0039] Furthermore, in this embodiment, the counterweight 7 has a concave surface 6 on the side facing the cylindrical member 4, and the curvature of the concave surface 6 is consistent with the curvature of the outer side of the magnet 5.

[0040] Please see Figure 7 and Figure 8In one embodiment of the present invention, the production apparatus further includes a transmission mechanism 13 for rotating the cylindrical component 4. The transmission mechanism 13 includes a first driven shaft 1301 rotatably disposed in the impregnation tank 2 and a second driven shaft 1303 rotatably disposed on the housing component 3. The second driven shaft 1303 has a square radial cross section. The first driven shaft 1301 is provided with a slot 1305 adapted to the second driven shaft 1303. Part of the shaft end of the second driven shaft 1303 is inserted into the slot 1305. The first driven shaft 1301 is driven to the driving disk 1205 by a first bevel gear set 1302. The second driven shaft 1303 is driven to the cylindrical component 4 by a second bevel gear set 1304. The transmission ratio of the first bevel gear set 1302 and the second bevel gear set 1304 is 1.

[0041] In this embodiment, the second driven shaft 1303 can move along the slot 1305 to adapt to the reciprocating movement of the housing 3. The drive disk 1205 rotates once to drive the housing 3 to complete one reciprocating cycle. Under the transmission action of the first bevel gear set 1302 and the second bevel gear set 1304, and the transmission ratio of the first bevel gear set 1302 and the second bevel gear set 1304 is 1, so when the drive disk 1205 rotates once, the first driven shaft 1301 and the second driven shaft 1303 are both driven to rotate once, thereby driving the cylindrical part 4 to rotate once.

[0042] Please see Figure 1 , Figure 2 and Figure 9 In one embodiment of the present invention, rows of pressure-receiving components 14 are provided inside the impregnation tank 2 on both sides of the polyester fabric conveying path, and the line connecting the two rows of pressure-receiving components 14 is perpendicular to the polyester fabric conveying path. A spring 15 is provided between each pressure-receiving component 14 and the tank wall of the impregnation tank 2, and a spring strip 16 is provided on each pressure-receiving component 14. Pressing components 11 for pressing the two rows of pressure-receiving components 14 are provided on both sides below the base plate 9.

[0043] In this embodiment, during the impregnation of polyester fabric, the counterweight 7 drives the two pressing parts 11 to cyclically contact / disengage from the two rows of pressing parts 14 when switching between the separation / piercing positions. Under the action of the spring 15, the two rows of pressing parts 14 continuously shake, thereby causing the elastic bar 16 to vibrate continuously, which in turn disturbs the solution and promotes solution penetration.

[0044] Furthermore, in this embodiment, the spring bar 16 is made of spring steel.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
