Description

Technical Field

[0001] The present application relates to the technical field of cloth drying, and in particular to a drying device for glass fiber cloth production. Background Art

[0002] The cloth needs to be desized during the production process. After desizing, the cloth is in a soaked state and needs to be dried and shaped by hot air to make the cloth stiff. At the same time, when the cloth is drying, the inside of the drying chamber needs to be kept at a high temperature. The cloth is in a soaked state and the liquid carrying rate is too high. In the process of the cloth running from the slurry pool to the drying room, the cloth travels slowly, resulting in reduced production efficiency.

[0003] Chinese patent CN117516105B authorized and announced on March 19, 2024 discloses a cloth drying device, wherein, by adjusting cloths of different thicknesses, the flow rate can be increased to match the drying of cloths of different thicknesses, so that the entire production process can be more consistent and controllable, and the same drying parameters can be used for both thin and thick cloths, simplifying the production operation, and a consistent drying rate can complete the drying of cloths of different thicknesses in the same time, which will improve production efficiency, reduce production time and cost, and reduce the quality difference caused by different drying time, making the quality of the cloth more stable, but for cloths of the same thickness, due to different weaving processes, the density of the wire harness weaving is different on the basis of the same thickness, especially for glass fiber cloth, the density of the cloth is different, and the application field is also different. If cloths of different densities are dried with the same hot air on the basis of the same thickness, the cloth fibers will also be damaged and cracked. Therefore, the present invention provides a drying device for glass fiber cloth production. Summary of the invention

[0004] The main purpose of the present application is to provide a drying device for glass fiber cloth production. During the drying process of glass fiber cloth of the same thickness, the size of the drying hot air is adjusted due to the different densities of the cloth, so as to achieve the adjustment of the size of the drying hot air for cloth of different densities.

[0005] To achieve the above-mentioned purpose, the present application provides a drying device for glass fiber cloth production, comprising a box body and a hot air blower for providing hot air inside the box body, wherein the inside of the box body comprises:

[0006] A sliding cavity is arranged in the upper half of the box body, and a sliding plate that can move up and down is slidably connected inside the sliding cavity, fixed rods that can slide the sliding plate are fixed at the front ends of both sides of the sliding cavity, and sleeve rods are fixedly connected to the rear ends of both sides of the top of the sliding plate, and a sleeve that can slide the sleeve rod is fixedly connected to the top of the sliding cavity at the position of the sleeve rod, and a collecting pipe that connects the two sleeves is connected to the top of the box body at the position of the sleeve;

[0007] A drying chamber is arranged in the lower half of the interior of the box body, and a cloth guide roller group 1 is arranged at equal intervals in the interior of the drying chamber along the length direction thereof, and a blow box is fixed in the interior of the drying chamber below the cloth guide roller group 1, and blow ports are opened at equal intervals on the top of the blow box, a connection port is opened on one side of the blow box, and a connection groove is arranged in the interior of the drying chamber at the position of the connection port, and an air inlet is opened at the rear end of the connection groove;

[0008] A ventilation pipe is fixed to the back of the box at the air inlet position, and the other end of the ventilation pipe is connected to the output end of the hot air blower. The top of the ventilation pipe close to one end of the box is connected with a liquid guide pipe 1, and the middle position of the collecting pipe is connected with a liquid guide pipe 2, and the other end of the liquid guide pipe 2 is connected to the other end of the liquid guide pipe 1 through a one-way valve, and the middle position of the liquid guide pipe 2 and the middle position of the liquid guide pipe 1 are connected through a return pipe, and a control valve is installed on the return pipe.

[0009] Preferably, cloth guide openings are provided on the boxes at both ends of the drying chamber, and cloth guide roller groups 2 are installed on the outer sides of the boxes at the cloth guide openings, and gear 2 is connected to the end of one of the cloth guide roller groups 2.

[0010] Preferably, a rotating rod is rotatably connected to the interior of the drying chamber above one of the cloth guide ports along its front-to-rear direction, and the top of the rotating rod extends to the outside of the rear end of the box body and is connected to gear one which meshes with gear two, and a gear plate is fixed on the rotating rod, and a crankshaft is rotatably connected to the middle position above the cloth guide port along its length direction, and one end of the crankshaft is connected to a toothed plate which meshes with the gear plate, and a hammer assembly is sleeved on the recess of the crankshaft.

[0011] Preferably, a slide groove is provided on both the front and rear sides of the box body where the hammer assembly is located, and the hammer assembly includes a hinge block sleeved on the crankshaft, wherein the bottom of the hinge block is hinged with a hinge plate, and the bottom end of the hinge plate is hinged with a hammer roller bracket, and a hammer roller is rotatably connected to the outer side of the hammer roller bracket, and sliders that slide along the slide groove are fixed at both ends of the hammer roller.

[0012] Preferably, a gate plate is slidably connected to the inside of the ventilation pipe near the air inlet position, and a trapezoidal opening is opened on the gate plate, and sliders 2 are fixed on both sides of the gate plate, and a sliding groove 2 for sliding of the sliders 2 is opened on the inner side of the ventilation pipe at the position of the sliders 2, a piston cavity is provided on the top of the ventilation pipe at the gate plate position, and a piston plate is slidably connected to the inside of the piston cavity, and the piston plate and the gate plate are connected by a connecting rod, and the liquid guide tube 1 is connected to the top of the inside of the piston cavity.

[0013] The benefits of the present application are as follows: first, due to the different densities of the fabrics, the wind force of the hot air passing through the fabrics is also different, and then the sliding plate is pushed up by the wind force passing through the fabrics. During the rising process of the sliding plate, the sleeve rod is pushed to move along the inside of the sleeve, thereby introducing the liquid inside the sleeve into the collecting pipe, and then passing through the second liquid guide pipe, the one-way valve and the first liquid guide pipe into the piston cavity in turn, thereby pushing the piston plate to move along the inside of the piston cavity, and at the same time pushing the gate-like ventilation pipe downward through the connecting rod. It is explained here that in the initial state, the corresponding opening area between the trapezoidal opening and the air inlet The maximum value is 0.0447 W / cm2, and because the trapezoidal opening is an equilateral trapezoidal structure, during the downward movement of the gate plate, the corresponding opening area between the trapezoidal opening and the air inlet gradually decreases, thereby changing the size of the hot air for drying the cloth, and adjusting the size of the drying hot air for cloths of different densities. When the sliding plate approaches a balanced state inside the sliding cavity, the sliding plate no longer moves upward. Since the one-way valve is one-way and the control valve is closed in the initial state, it is ensured that the corresponding opening area between the trapezoidal opening and the air inlet always maintains the corresponding opening area during the drying process of cloths of the same density.

[0014] Secondly, through the mutual meshing between gear two and gear one, the rotating rod and the gear plate rotate synchronously, and because the gear plate and the toothed plate mesh with each other, the toothed plate and the crankshaft rotate synchronously. During the rotation of the crankshaft, the multiple groups of hammer assemblies mounted on the crankshaft reciprocate up and down, thereby causing the cloth to vibrate during the reciprocating motion, thereby accelerating the dripping of water droplets attached to the cloth and improving the drying effect. At the same time, during the reciprocating motion of the hammer assembly, the cloth is pressed down, thereby performing a preliminary test on the tension of the cloth in disguise.

[0028] See also Figure 1-Figure 5 This embodiment provides a drying device for glass fiber cloth production, including a box body 100 and a hot air blower 200 for providing hot air inside the box body 100, and the inside of the box body 100 includes:

[0029] The sliding chamber 110 is arranged in the upper half of the box body 100, and a sliding plate 111 that can move up and down is slidably connected inside the sliding chamber 110, and fixed rods 114 that can slide the sliding plate 111 are fixed to the front ends of both sides of the sliding chamber 110, and sleeve rods 112 are fixedly connected to the rear ends of both sides of the top of the sliding plate 111, and a sleeve 113 that can slide the sleeve rod 112 is fixedly connected to the top of the sliding chamber 110 at the position of the sleeve rod 112, and a sleeve 113 that connects the two sleeves is connected to the top of the box body 100 at the position of the sleeve 113. The collecting tube 140 of the tube 113, on the basis of the same thickness, uses the same hot air to dry fabrics of different densities, which is easy to cause the fabric fibers to be damaged and cracked. Therefore, in the process of drying the fabrics, due to the different densities of the fabrics, the wind force of the hot air passing through the fabrics is also different. Then, the sliding plate 111 is pushed up by the wind force passing through the fabrics. During the process of the sliding plate 111 rising, the sleeve rod 112 is pushed to move along the inside of the sleeve 113, so that the liquid inside the sleeve 113 is introduced into the collecting tube 140;

[0030] The drying chamber 120 is arranged in the lower half of the box body 100, and a cloth guide roller group 121 is evenly spaced in the drying chamber 120 along the length direction thereof, and a blow box 124 is fixed in the drying chamber 120 below the cloth guide roller group 121, and blow holes 123 are evenly spaced on the top of the blow box 124, a connection port 127 is provided on one side of the blow box 124, and a connection groove 128 is provided in the drying chamber 120 at the position of the connection port 127, and an air inlet 129 is provided at the rear end of the connection groove 128, and a hot air source is provided by the hot air blower 200, passes through the ventilation pipe 300 and the connection groove 128 in sequence, and then enters the blow box 124 to dry the cloth through the blow hole 123;

[0031] The ventilation pipe 300 is fixed to the back of the box 100 at the position of the air inlet 129, and the other end of the ventilation pipe 300 is connected to the output end of the hot air blower 200. The top of the ventilation pipe 300 near one end of the box 100 is connected to the liquid guide pipe 150, and the middle position of the collecting pipe 140 is connected to the liquid guide pipe 2 160, and the other end of the liquid guide pipe 2 160 is connected to the other end of the liquid guide pipe 1 150 through a one-way valve 180, and the middle position of the liquid guide pipe 2 160 and the middle position of the liquid guide pipe 1 150 are connected through a return pipe 170, and a control valve 190 is installed on the return pipe 170. When the sliding plate 111 is in the sliding cavity 110, the liquid guide pipe 150 is connected to the return pipe 170. When the interior tends to a balanced state (the sliding plate 111 no longer moves upward), since the one-way valve 180 is a one-way passage and the control valve 190 is closed in the initial state, it is ensured that the corresponding opening area between the trapezoidal opening 307 and the air inlet 129 always maintains the corresponding opening area during the drying process of the cloth with the same density. Subsequently, when drying cloths of other densities, it is only necessary to control the control valve 190 to open through the controller, and reset it under the action of gravity of the sliding plate 111, and the liquid returns to the inside of the sleeve 113 from the liquid guide tube 150, the return liquid tube 170 and the liquid guide tube 2 160, so that the size of the hot air can be adjusted again when drying cloths of other densities.

[0032] In this embodiment, cloth guide openings 1211 are provided on the box body 100 at both ends of the drying chamber 120, and cloth guide roller group 2 130 is installed on the outer side of the box body 100 at the cloth guide opening 1211, and a gear 2 131 is connected to the end of one of the cloth guide roller groups 130. In the subsequent process of cloth production, the cloth is rolled up, so that during the cloth movement, the cloth guide roller group 2 130 is in a rolling state. Therefore, the gear 2 131 and the gear 1 1214 are meshed with each other, so that the rotating rod 1212 and the gear plate 1213 rotate synchronously.

[0033] In this embodiment, a rotating rod 1212 is rotatably connected to the drying chamber 120 above one of the cloth guide ports 1211 along its front-to-back direction, and the top of the rotating rod 1212 extends to the outside of the rear end of the box body 100 and is connected to a gear 1 1214 meshing with the gear 2 131, and a gear plate 1213 is fixed on the rotating rod 1212, and a crankshaft 122 is rotatably connected to the middle position above the cloth guide port 1211 along its length direction, and one end of the crankshaft 122 is connected to a toothed plate 1210 meshing with the gear plate 1213, and a hammer assembly 125 is sleeved on the recessed part of the crankshaft 122, through the gear 2 131 and the gear 1 1214 The gear plates 1213 and the toothed disc 1210 are meshed with each other, so that the rotating rod 1212 and the gear plate 1213 rotate synchronously, and because the gear plate 1213 and the toothed disc 1210 are meshed with each other, the toothed disc 1210 and the crankshaft 122 rotate synchronously. During the rotation of the crankshaft 122, the multiple groups of hammer assemblies 125 sleeved on the crankshaft 122 perform up and down reciprocating motion, so that the cloth has a shaking effect during the reciprocating motion, thereby accelerating the dripping of water droplets attached to the cloth and improving the drying effect. At the same time, during the reciprocating motion of the hammer assembly 125, since it will produce a downward pressure effect on the cloth, the tension of the cloth is also preliminarily detected in disguise.

[0034] In this embodiment, a slide groove 126 is provided on both the front and rear sides of the box body 100 at the position of the hammer assembly 125, and the hammer assembly 125 includes a hinge block 1251 sleeved on the crankshaft 122, wherein the bottom of the hinge block 1251 is hinged with a hinge plate 1252, and the bottom end of the hinge plate 1252 is hinged with a hammer roller bracket 1253, and a hammer roller 1254 is rotatably connected to the outer side of the hammer roller bracket 1253, and sliders 1255 that slide along the slide groove 126 are fixed to both ends of the hammer roller 1254.

[0035] like Figure 4As shown, in this embodiment, a gate plate 302 is slidably connected inside the ventilation pipe 300 near the air inlet 129, and a trapezoidal opening 307 is opened on the gate plate 302, and two sliders 306 are fixed on both sides of the gate plate 302, and a slide groove 301 for sliding the two sliders 306 is opened inside the ventilation pipe 300 at the position of the two sliders 306, and a piston cavity 305 is provided on the top of the ventilation pipe 300 at the position of the gate plate 302, and a piston plate 304 is slidably connected inside the piston cavity 305, and the piston plate 304 is connected to the gate plate 302 by a connecting rod 303, and the liquid guide tube 150 is connected to the piston cavity The top of 305 is connected, and the liquid enters the piston cavity 305, thereby pushing the piston plate 304 to move along the inside of the piston cavity 305, and at the same time pushing the gate plate 302 and the ventilation pipe 300 to move downward through the connecting rod 303. It is explained here that in the initial state, the opening area corresponding to the trapezoidal opening 307 and the air inlet 129 is the largest, and because the trapezoidal opening 307 is an equilateral trapezoidal structure, therefore, in the process of the gate plate 302 moving downward, the opening area corresponding to the trapezoidal opening 307 and the air inlet 129 gradually becomes smaller, thereby changing the size of the hot air for drying the cloth, and adjusting the size of the hot air for drying the cloth according to different densities.

[0036] In summary:

[0037] First, the glass fiber cloth is introduced into the drying chamber 120 from one of the cloth guide ports 1211 at both ends of the box 100, and then the glass fiber cloth is passed through the cloth guide roller group 121 and discharged from the cloth guide port 1211 at the other end. It is explained here that on the basis of the same thickness, cloths of different densities are dried with the same hot air, which is easy to cause the cloth fibers to be damaged and cracked. Therefore, in the process of drying the cloth, the hot air source is provided by the hot air blower 200, which passes through the ventilation pipe 300 and the connecting groove 128 in sequence, and then enters the blowing box 124 to dry the cloth through the blowing port 123. In the process of drying the cloth, due to the different densities of the cloth, the wind force of the hot air passing through the cloth is also different, and then the hot air passes through the blowing box 124. The wind force of the cloth pushes the sliding plate 111 to rise. During the process of the sliding plate 111 rising, the sleeve rod 112 is pushed to move along the inside of the sleeve 113, so that the liquid inside the sleeve 113 is introduced into the collecting pipe 140, and then enters the piston cavity 305 through the second liquid guide tube 160, the one-way valve 180 and the first liquid guide tube 150 in sequence, so as to push the piston plate 304 to move along the inside of the piston cavity 305, and at the same time, the gate plate 302 is pushed by the connecting rod 303 to move the ventilation pipe 300 downward. It is explained here that in the initial state, the corresponding opening area between the trapezoidal opening 307 and the air inlet 129 is the largest, and because the trapezoidal opening 307 is an equilateral trapezoidal structure, therefore, during the process of the gate plate 302 moving downward, the trapezoidal opening 307 and the air inlet 129 are The corresponding opening area between the air inlet 129 gradually becomes smaller, thereby changing the size of the hot air for drying the cloth, and adjusting the size of the hot air for drying the cloth with different densities. When the sliding plate 111 tends to a balanced state inside the sliding chamber 110 (the sliding plate 111 is no longer moving upward), since the one-way valve 180 is a one-way passage and the control valve 190 is in a closed state in the initial state, it is ensured that the corresponding opening area between the trapezoidal port 307 and the air inlet 129 always maintains a corresponding opening area during the drying process of the cloth with the same density. It is explained here that due to the different sizes of the wind force passing through the cloth, the sliding plate 111 is pushed to different heights at different positions. In this process, the wind force blowing directly on the sliding plate 111 will also blow to both sides. Although the box 100 seems to be relatively sealed, it still has gaps, such as the cloth guide port 1211. For example, when a ping-pong ball is blown with a blower, the ping-pong ball will stay at different heights due to the different wind forces. The nature of the present invention is consistent with this. The wind force is reflected by cloths of different densities. In the initial state, the control valve 190 is in a closed state. Then, when drying cloths of other densities, it is only necessary to control the control valve 190 to open through the controller, and reset it under the gravity of the sliding plate 111. The liquid returns to the inside of the sleeve 113 from the liquid guide pipe 150, the liquid return pipe 170 and the liquid guide pipe 2 160, so that the hot air size can be adjusted again when drying cloths of other densities.

[0038] At the same time, due to the winding of the cloth in the subsequent process during the cloth production process, the cloth guide roller group 2 130 is in a rolling state during the cloth travel. Therefore, the gear 2 131 and the gear 1 1214 are meshed with each other, so that the rotating rod 1212 and the gear plate 1213 rotate synchronously, and because the gear plate 1213 and the toothed plate 1210 are meshed with each other, the toothed plate 1210 and the crankshaft 122 rotate synchronously. During the rotation of the crankshaft 122, the multiple groups of hammer assemblies 125 mounted on the crankshaft 122 reciprocate up and down, so that the cloth has a shaking effect during the reciprocating motion, thereby accelerating the dripping of water droplets attached to the cloth and improving the drying effect. At the same time, during the reciprocating motion of the hammer assembly 125, since it will produce a downward pressure effect on the cloth, the tension of the cloth is also preliminarily detected in disguise.
