Description

Technical Field

[0001] The invention relates to the technical field of nonwoven fabric production, in particular to a shaping device for nonwoven fabric production. Background Art

[0002] Nonwoven fabric is a kind of fabric that can be produced without traditional textile process. The shaping equipment of nonwoven fabric is mainly used to ensure the stability of size and shape of nonwoven fabric, so that the nonwoven fabric can maintain good performance in the subsequent processing and use. The shaping equipment includes heat setting machine, calender, oven, cooling setting machine, etc. Different equipment can be used according to different types of materials.

[0003] When using an oven to shape the non-woven fabric, hot air is circulated to dry and shape the non-woven fabric at a certain temperature. When the existing oven is working, the heater is used to heat the interior of the oven as a whole, so that the non-woven fabric is dried through the high-temperature gas environment in the oven. This drying method will result in slow drying efficiency because the non-woven fabric does not directly contact the heat source, especially when it comes to thick non-woven fabrics, the time used is longer; secondly, the existing oven will also dry the non-woven fabric through a heating chamber and a fan. In this way, the hot air discharged by the fan is directly blown to the non-woven fabric. This method is more efficient than the above method. After the hot air blows to the non-woven fabric, the wind-receiving surface of the non-woven fabric will produce water vapor floating upward. At the same time, the thicker the non-woven fabric, the more water vapor it generates. The rising water vapor will counteract the hot air blowing to the non-woven fabric, so that the hot air is subject to resistance, which in turn causes the hot air to be unable to act directly on the non-woven fabric, which will also cause the problem of low drying efficiency and long drying time. Summary of the invention

[0004] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a shaping device for nonwoven fabric production.

[0005] The technical solution is as follows: a shaping device for non-woven fabric production, comprising: a drying box, the drying box being equipped with a hot air blower; a fixed plate, fixedly connected to the drying box, the fixed plate being provided with a guide groove, the guide groove being connected to the air outlet of the hot air blower; a guide block, fixedly connected to the fixed plate; a circulation shell, fixedly connected to the fixed plate, the circulation shell being provided with a guide surface; two air guide shells, both fixedly connected to the drying box and respectively connected to the two sides of the circulation shell; an exhaust shell, fixedly connected to the drying box, the two air guide shells being respectively connected to the two sides of the exhaust shell, the exhaust shell being provided with a plurality of exhaust ports; an exhaust module, installed on one side of the drying box and connected to the drying box, the guide block being located between the guide groove and the exhaust module.

[0006] Furthermore, the thickness of the guide block gradually increases from a side close to the circulation shell to a side close to the exhaust module.

[0007] Furthermore, the exhaust port is arranged at an angle, and the exhaust port is gradually inclined from top to bottom toward a side close to the exhaust module.

[0008] Furthermore, symmetrically distributed shielding strips are fixedly connected to the lower side of the guide block.

[0009] Furthermore, an air guide member is fixedly connected in the circulation shell, and the air guide member is provided with two arc-shaped surfaces, which are respectively facing the adjacent air guide shells.

[0010] Furthermore, it also includes: two air outlet shells, which are respectively fixed and connected to the adjacent air guide shells, and the air outlet shells are located between the symmetrically distributed shielding strips; and two dispersion shells, which are distributed up and down, both of which are fixed and connected to the air guide shells, and the air outlet shell is located between the two dispersion shells.

[0011] Furthermore, the inner diameter of the air outlet housing gradually decreases from close to the adjacent air guide housing to the other side.

[0012] Furthermore, it also includes: rotating shafts, the number of which is consistent with the number of the dispersion shells, which are rotatably connected to adjacent dispersion shells; shielding plates, the number of which is consistent with the number of the rotating shafts, which are respectively fixed to adjacent rotating shafts and sealed with adjacent dispersion shells; a detection mechanism, which is arranged in the drying box and is used to detect the humidity of the material.

[0013] Furthermore, the detection mechanism includes: a fixed base, fixedly connected to the drying box; a humidity detector, installed on the fixed base, for detecting the humidity of the cloth; and a driving component, arranged on the fixed base, for driving all the baffles to deflect.

[0014] Furthermore, the driving assembly includes: two electric push rods, both fixed to the drying box; rack racks, the number of which is consistent with the number of the rotating shafts, respectively fixed to the telescopic ends of the adjacent electric push rods; gears, the number of which is consistent with the number of the rotating shafts, respectively fixed to the adjacent rotating shafts and meshing with the adjacent rack racks.

[0015] The present invention has the following advantages: the present invention guides the hot air to between the guide surface and the guide block, so that the hot air flows along the curved surface of the guide block and evaporates the moisture in the non-woven fabric. At the same time, based on the Coanda effect, negative pressure is generated on the lower side of the guide block. At the same time, the negative pressure will cause the water vapor in the non-woven fabric to tend to move outward, thereby accelerating the discharge of water vapor in the non-woven fabric, thereby accelerating the drying of the non-woven fabric.

[0016] The present invention moves the water vapor to the right, out from between the guide block and the non-woven fabric, through the guide block, and moves the water vapor to the exhaust module, thereby accelerating the discharge of the water vapor and further reducing the influence of the water vapor on the temperature in the drying box.

[0017] The present invention gradually increases the thickness of the guide block from the front to the back, that is, the distance between the lower side of the guide block and the non-woven fabric gradually decreases from the front to the back, thereby reducing the flow area between the two, thereby accelerating the flow rate of hot air and water vapor between the two, thereby accelerating the discharge of water vapor, and then accelerating the discharge of moisture in the non-woven fabric, thereby improving the efficiency of drying the non-woven fabric, and thereby accelerating the shaping of the non-woven fabric.

[0018] The present invention intercepts the hot air between the guide block and the non-woven fabric through symmetrically distributed shielding strips, reducing the degree of hot air between the guide block and the non-woven fabric escaping to the left and right sides of the guide block, so that the hot air flowing through the guide block can fully contact the non-woven fabric, thereby improving the efficiency of drying the non-woven fabric.

[0019] The present invention detects the water storage amount of the non-woven fabric in real time through a humidity detector, controls the deflection angle of the shielding plate, and then adjusts the area of ​​the dispersion shell blowing hot air toward the non-woven fabric, thereby accelerating the drying efficiency of the non-woven fabric and further improving the shaping efficiency of the non-woven fabric.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0023] Research has found that when the existing oven is performing the shaping operation on the non-woven fabric, the non-woven fabric will be dried by the hot air in the oven. During the drying operation, the hot air comes into contact with the non-woven fabric, causing the moisture inside to evaporate and generate water vapor. The water vapor will move upward and hinder the contact between the hot air and the non-woven fabric, which will also slow down the drying efficiency of the non-woven fabric.

[0024] When the existing oven dries the non-woven fabric, the water vapor generated will move upwards. The location where the oven collects the water vapor is generally located on one side of the oven, and the collection port is small. At the same time, the collection operation is timed, so the water vapor cannot be fully discharged, resulting in water vapor remaining in the oven, which in turn affects the temperature in the oven and reduces the drying efficiency. To this end, the following solutions are proposed, as follows: Nonwoven production equipment, combined with Figure 1-Figure 5 As shown, it includes: a drying box 1, which is equipped with a hot air blower 2; a fixed plate 3, which is fixedly connected to the drying box 1, and the fixed plate 3 is provided with a guide groove 301, and the guide groove 301 is connected to the air outlet of the hot air blower 2; a guide block 4, which is fixedly connected to the fixed plate 3; a circulation shell 5, which is fixedly connected to the fixed plate 3, and the circulation shell 5 is provided with a guide surface 501; there are two air guide shells 6, which are both fixedly connected to the drying box 1 and are respectively connected to the two sides of the circulation shell 5; an exhaust shell 7, which is fixedly connected to the drying box 1, and the two air guide shells 6 are respectively connected to the two sides of the exhaust shell 7, and the exhaust shell 7 is provided with a plurality of exhaust ports 701; an exhaust module 8, which is installed on one side of the drying box 1 and is connected to the drying box 1, and the guide block 4 is located between the guide groove 301 and the exhaust module 8.

[0025] In the above scheme, a method of changing the direction of water vapor movement is proposed to reduce the obstruction effect of water vapor on hot air; the number of drying boxes 1 in this scheme can be set according to actual needs, and several drying boxes 1 are interconnected to form a drying line. The figure shows two of them, and a connecting shell is provided between two adjacent drying boxes 1 for non-woven fabrics to pass through; guide rollers can be provided on both the front and rear side shells of the drying box 1 to guide the non-woven fabrics entering and exiting the drying box 1 to ensure the stability of the movement of the non-woven fabrics; the hot air blower 2 is an existing device, which is composed of a heater and a fan inside, so as to complete the heating of air and circulation of hot air In order to achieve the effect, each drying box 1 is equipped with a hot air blower 2, and the temperature of the hot air discharged by all the hot air blowers 2 in the entire drying line can be adjusted (decreased in sequence); the cross-section of the guide groove 301 is a right-angled trapezoid, the inclination direction of the guide surface 501 is opposite to the inclination direction of the upper inclined surface of the guide groove 301, and the guide surface 501 is located in the guide groove 301, and the hot air flowing through the guide groove 301 is diverted by the guide surface 501, so that the two hot airs enter the circulation shell 5 and the lower side of the guide block 4 respectively; the lower side surface of the guide block 4 is a curved surface, so as to guide the passing hot air; the non-woven fabric is located between the guide block 4 and the exhaust shell 7.

[0026] This scheme utilizes the existing Coanda effect, which means that when a fluid (such as gas or liquid) flows through a convex surface, it tends to flow along the surface rather than directly leaving the surface. At the same time, when the fluid flows along the surface, a low-pressure area is generated in the area, thereby affecting the movement of the surrounding fluid.

[0027] Working process: When the non-woven fabric is being shaped, the hot air blower 2 is turned on, and the hot air blower 2 blows the hot air into the drying box 1. Then the hot air flows through the guide groove 301 and is diverted by the guide surface 501. A part of the hot air enters the circulation shell 5 and enters the two guide shells 6. Finally, the hot air enters the exhaust shell 7 and is discharged from the exhaust port 701, so that the hot air dries the lower side of the non-woven fabric; the other part of the hot air is diverted to between the guide surface 501 and the guide block 4, and the hot air flows along the curved surface of the guide block 4. In the process of the hot air flowing, the hot air evaporates the moisture in the non-woven fabric, and at the same time, in the process of flowing In the process, negative pressure will be generated on the lower side of the guide block 4, and the negative pressure will make the water vapor in the non-woven fabric tend to move outward, accelerating the discharge of water vapor in the non-woven fabric, thereby accelerating the drying of the non-woven fabric. In the process of hot air flow, the hot air will push the generated water vapor backward, thereby reducing the obstruction effect of water vapor on the hot air, so that the hot air can fully contact the non-woven fabric, and the water vapor moves to the right between the guide block 4 and the non-woven fabric until the water vapor moves to the exhaust module 8. The exhaust module 8 accelerates the discharge of water vapor, thereby reducing the influence of water vapor on the temperature in the drying box 1. After the non-woven fabric is set, the hot air blower 2 is turned off.

[0028] Combination Figure 3 and Figure 4 As shown, the thickness of the guide block 4 gradually increases from the side close to the flow shell 5 to the side close to the exhaust module 8 .

[0029] In the above scheme, the shape of the guide block 4 is further limited, and the thickness of the guide block 4 gradually increases from the front to the back, that is, the distance between the lower side of the guide block 4 and the non-woven fabric gradually decreases from front to back, and the flow area between the two is reduced, thereby accelerating the flow rate of hot air and water vapor between the two, thereby accelerating the discharge of water vapor, and then accelerating the discharge of moisture in the non-woven fabric, improving the efficiency of drying the non-woven fabric, and then accelerating the shaping of the non-woven fabric.

[0030] Combination Figure 4 and Figure 5 As shown, the air outlet 701 gradually inclines from top to bottom toward the side close to the air exhaust module 8 .

[0031] In the above scheme, the inclination direction of the exhaust port 701 is specifically defined, so that the hot air discharged from the exhaust port 701 is blown backwards, pushing the generated water vapor, accelerating the speed at which the water vapor enters the exhaust module 8, and reducing the impact of the water vapor on the hot air, thereby improving the efficiency of drying the non-woven fabric.

[0032] Combination Figure 3-Figure 5 As shown, symmetrically distributed shielding strips 21 are fixedly connected to the lower side of the guide block 4 .

[0033] In the above scheme, the main problem addressed is that in the process of hot air flowing along the lower side of the guide block 4, the hot air will disperse to the left and right sides, which will cause a reduction in the air volume of the hot air between the guide block 4 and the non-woven fabric; there are two shielding strips 21, and the two shielding strips 21 are respectively located on the left and right sides of the guide block 4, so that the hot air between the guide block 4 and the non-woven fabric is intercepted by the symmetrically distributed shielding strips 21, reducing the degree of hot air between the guide block 4 and the non-woven fabric escaping to the left and right sides of the guide block 4, so that the hot air flowing through the guide block 4 is fully in contact with the non-woven fabric, thereby improving the efficiency of drying the non-woven fabric.

[0034] Combination Figure 4 and Figure 5 As shown, an air guide member 31 is fixedly connected in the circulation shell 5 , and the air guide member 31 is provided with two arc-shaped surfaces, which are respectively facing the adjacent air guide shells 6 .

[0035] In the above scheme, a method for accelerating the discharge speed of hot air in the circulation shell 5 is proposed, and the arc surface of the air guide member 31 guides the passing hot air so that the hot air is directly connected to the air guide shell 6 along the arc surface. In this way, the speed of the hot air in the circulation shell 5 moving to the air guide shell 6 is accelerated, and at the same time, the residual hot air in the circulation shell 5 is reduced.

[0036] Combination Figure 3 and Figure 6-Figure 9As shown, it also includes: two air outlet shells 41, which are respectively fixed and connected to the adjacent air guide shells 6, and the air outlet shells 41 are located between the symmetrically distributed shielding strips 21; a dispersion shell 42, which has two upper and lower distributions, both of which are fixed and connected to the air guide shell 6, and the air outlet shell 41 is located between the two dispersion shells 42; the inner diameter of the air outlet shell 41 gradually decreases from close to the adjacent air guide shell 6 to the other side.

[0037] In the above scheme, a method of secondary drying of the non-woven fabric is proposed to speed up the drying efficiency; the two air outlet shells 41 are respectively located on the left and right sides of the non-woven fabric, and the height of the inner diameter of the opposite sides of the two air outlet shells 41 is greater than the thickness of the non-woven fabric, so that part of the hot air discharged from the air outlet shells 41 contacts the left and right sides of the non-woven fabric, and the other part is located on the upper and lower sides of the non-woven fabric, and the hot air on the left and right sides will collide with each other. After the hot air on the left and right sides collide, the direction of the hot air will change, and part of the hot air will be diverted along the upper and lower sides of the collision point to form a new The flow path of the hot air diverted up and down is combined with the hot air and water vapor moving backward from the lower side of the guide block 4, so as to accelerate the speed of the water vapor moving to the exhaust module 8; by gradually changing the inner diameter of the air outlet shell 41, the flow area of ​​the air outlet shell 41 for discharging the hot air is reduced, the speed of hot air discharge in the air outlet shell 41 is accelerated, and then the impact of the hot air on the left and right sides of the non-woven fabric is increased, and the discharge speed of water vapor inside the non-woven fabric is accelerated; an air outlet is provided on the front side of the dispersion shell 42, that is, after the hot air enters the dispersion shell 42, it is discharged from the air outlet thereon, and the hot air is discharged forward.

[0038] Working process: after the hot air enters the air guide shell 6, a part of the hot air enters the exhaust shell 7 to dry the lower side of the non-woven fabric, and the other part of the hot air moves backward along the air guide shell 6. During this process, a part of the hot air moving along the air guide shell 6 is discharged from the air outlet shell 41, and the discharged hot air blows to the left and right sides of the non-woven fabric to accelerate the discharge of water vapor in the non-woven fabric. At the same time, the discharged hot air flows along the upper and lower sides of the non-woven fabric, and the hot air on the left and right sides collide. The hot air after the collision flows to the upper and lower sides respectively to accelerate the discharge of water vapor. The other part of the hot air will enter the upper and lower dispersion shells 42 respectively. At this time, the hot air in the dispersion shell 42 is discharged forward, which increases the degree of chaos of the airflow in the drying box 1, thereby promoting the temperature in the drying box 1 to be uniform.

[0039] Combination Figure 7 and Figure 8 As shown, it also includes: rotating shafts 51, the number of which is consistent with the number of dispersion shells 42, and are rotatably connected to adjacent dispersion shells 42; shielding plates 52, the number of which is consistent with the number of rotating shafts 51, are respectively fixed to adjacent rotating shafts 51, and are sealed with adjacent dispersion shells 42; a detection mechanism is arranged in the drying box 1, and is used to detect the humidity of the material.

[0040] In the above scheme, a method of changing the flow direction of the hot air in the dispersion shell 42 is proposed; the baffle plate 52 is used to block the hot air passing through the dispersion shell 42 (that is, to block the air outlet of the dispersion shell 42). When the upper and lower baffle plates 52 are both in a vertical state, the air outlet of the dispersion shell 42 is blocked, and the two baffle plates 52 guide the hot air of the dispersion shell 42, so that the hot air in the two dispersion shells 42 moves in opposite directions, thereby changing the flow direction of the hot air, and changing the hot air blowing forward to blowing toward the non-woven fabric, thereby increasing the contact area between the non-woven fabric and the hot air, and further improving the efficiency of drying the non-woven fabric; initially, the baffle plate 52 is flush with the adjacent dispersion shell 42, so that the hot air flowing through the dispersion shell 42 is not affected and can be blown directly forward, and there is no obstruction between the upper and lower baffle plates 52 (such as Figure 8 as shown).

[0041] Combination Figure 3 and Figure 7 As shown, the detection mechanism includes: a fixed seat 61, fixedly connected to the drying box 1; a humidity detector 62, installed on the fixed seat 61, for detecting the humidity of the cloth. When the non-woven fabric passes over the upper side of the humidity detector 62, the humidity detector 62 detects the humidity of the non-woven fabric to determine the moisture content inside the non-woven fabric; a driving component, arranged on the fixed seat 61, for driving all the shielding plates 52 to deflect.

[0042] Combination Figure 3 , Figure 7 and Fig. 9 As shown, the driving assembly includes: two electric push rods 71, both of which are fixed to the drying box 1. The electric push rod 71 is an existing structure, and its internal structure is not described here. The humidity detector 62 is electrically connected to the electric push rod 71. The larger the value displayed by the humidity detector 62, the longer the telescopic end of the electric push rod 71 extends; rack racks 72, the number of which is consistent with the number of rotating shafts 51, and are respectively fixed to the telescopic ends of adjacent electric push rods 71; gears 73, the number of which is consistent with the number of rotating shafts 51, are respectively fixed to adjacent rotating shafts 51, and mesh with adjacent rack racks 72.

[0043] Working process: When the non-woven fabric is being shaped, as the non-woven fabric gradually moves backward, the moisture in the non-woven fabric gradually decreases. During this process, the non-woven fabric passes through the humidity detector 62, and the humidity detector 62 constantly detects the humidity of the non-woven fabric. When the moisture content in the non-woven fabric is high, the humidity detector 62 transmits a signal to the electric push rod 71, and the telescopic ends of the two electric push rods 71 ​​are slowly extended, and the telescopic ends of the two electric push rods 71 ​​respectively drive the adjacent racks 72 to move, and the rack 72 drives the gear 73 to rotate, and the gear 73 drives the adjacent rotating shaft 51 to rotate, and the rotating shaft 51 drives the baffle plate 52 thereon to rotate, so that the baffle plate 52 is deflected, and the baffle plate 52 blocks the air outlet of the dispersion shell 42, thereby reducing the amount of hot air discharged from the air outlet of the dispersion shell 42.

[0044] After the baffle plate 52 is deflected, the baffle plate 52 gradually blocks the air outlet of the dispersion shell 42, and the baffle plate 52 gradually rotates from a horizontal state to a vertical state. During this process, the baffle plate 52 guides the hot air in the dispersion shell 42, and the hot air in the upper and lower dispersion shells 42 move in opposite directions, so that the exhausted hot air is directed toward the non-woven fabric, and the non-woven fabric is dried for the second time. At the same time, the contact area between the non-woven fabric and the hot air is increased, thereby improving the drying efficiency of the non-woven fabric.

[0045] When the non-woven fabric passes through the humidity detector 62, the humidity detector 62 detects the moisture content of the non-woven fabric in real time. That is, the more moisture the non-woven fabric has, the greater the distance the transmission rack 73 moves, and the greater the deflection angle of the baffle plate 52. That is, the greater the baffle plate 52 blocks the air outlet of the dispersion shell 42, and the larger the gap between the baffle plate 52 and the dispersion shell 42, the more hot air flows toward the non-woven fabric, thereby improving the efficiency of drying the non-woven fabric.

[0046] When the humidity detector 62 detects that the moisture content of the non-woven fabric decreases, the humidity detector 62 drives the shielding plate 52 to reset via the electric push rod 71 .
