Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric drying, and specifically provides a drying device for non-woven fabric processing. Background Art

[0002] Non-woven fabric, also known as non-woven fabric or needle-punched non-woven fabric, is a kind of fabric formed without traditional textile process. After the fibers are oriented or randomly arranged, they are reinforced by mechanical, hot melt or chemical methods to give them a certain strength and structure. During the processing, the non-woven fabric is reinforced by interweaving the fibers through high-pressure water flow. This method is called spunlace. After spunlace, the non-woven fabric needs to be dried to remove residual moisture and ensure the dryness and stability of the non-woven fabric.

[0003] At present, when non-woven fabrics are dried, if a blowing drying source is used to blow and dry the non-woven fabrics at a close distance, the non-woven fabrics are easily deformed due to local overheating and the effect of wind, affecting the quality of the non-woven fabrics.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] See also Figure 1 A drying device for non-woven fabric processing includes: a fixed base 1, two fixed plates 2 are installed on the top of the fixed base 1, and a cloth conveying mechanism 3 is arranged between the two fixed plates 2 and the fixed base 1.

[0032] See also Figure 1 , Figure 3 and Figure 6The cloth winding conveying mechanism 3 includes two fixed top plates 30 installed between the two fixed plates 2 and arranged symmetrically along the length direction thereof. A plurality of conveying rollers 31 evenly arranged along the length direction of the fixed top plates 30 are rotatably connected between the fixed top plates 30 and the fixed base 1. The conveying rollers 31 connected to the two fixed top plates 30 are staggered along the length direction of the fixed top plates 30. A conveying drive group 32 located on the fixed base 1 is commonly installed at the bottom between the plurality of conveying rollers 31 connected to the lower end of one of the fixed top plates 30. The non-woven fabric 5 is wound around the plurality of conveying rollers 31 in a wave shape.

[0033] The two fixed plates 2 are each provided with a rectangular through groove for passing the nonwoven fabric 5. The nonwoven fabric 5 after preliminary squeezing and drainage after spunlacing is inserted between the two fixed plates 2 and wrapped around a plurality of conveying rollers 31. The conveying drive group 32 drives the plurality of conveying rollers 31 located on the same horizontal line to rotate, and the conveying rollers 31 drive the nonwoven fabric 5 to move.

[0034] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 A drying mechanism 4 is installed between the two fixed plates 2. The drying mechanism 4 includes two groups of plug-in racks. Each group of plug-in racks is composed of a plurality of plug-in racks 40 located below the fixed top plate 30 and a fixed rack 42 installed together at the ends of the plug-in racks 40. The conveying rollers 31 connected to the bottom of the same fixed top plate 30 are arranged alternately with the plug-in racks 40. The plug-in racks 40 correspond to the conveying rollers 31 on the opposite side thereof one by one, and a plug-in supporting guide group 43 is installed between the plug-in racks 40 and the conveying rollers 31 on the opposite side thereof. A sliding driving group 44 connected to the plug-in racks and driving the two groups of plug-in racks to slide is installed between the two fixed plates 2. In one of the plug-in racks, a plurality of plug-in racks are connected to the fixed top plate 30. The end surface of the insertion rack 40 near the non-woven fabric 5 is equipped with a blowing pipe 45 evenly arranged along the length direction of the insertion rack 40, and the end surface of the insertion rack 40 near the non-woven fabric 5 in the other insertion rack is equipped with a supporting strip 47 corresponding to the blowing pipe 45 through a supporting leg 46. The side of the blowing pipe 45 near the non-woven fabric 5 is provided with blowing holes evenly arranged from top to bottom, and the supporting strip 47 is provided with a plurality of exhaust holes. The insertion rack connected with the blowing pipe 45 is provided with a blowing and drying air source group 48, and the insertion rack 40 is provided with a lifting and reciprocating group 49 which cooperates with the conveying drive group 32 to drive the multiple blowing pipes 45 connected to the insertion rack 40 to move back and forth up and down at the same time.

[0035] The sliding drive group 44 drives the insertion and displacement rack to move, so that the insertion rack 40 is aligned and inserted with the relative conveying roller 31 through the support guide group 43, so as to avoid the end of the insertion rack 40 away from the fixed frame 42 being suspended in the air, affecting the stability of the insertion rack 40. The horizontal section of the non-woven fabric 5 wrapped around the conveying roller 31 is located between two adjacent insertion racks 40, so that the blowing holes on the blowing pipe 45 are close to the non-woven fabric 5. The blowing and drying air source group 48 conveys hot air into the blowing pipe 45, and the hot air is blown vertically to the non-woven fabric 5 through the blowing holes to dry the non-woven fabric 5. By directly conveying the hot air to the surface of the non-woven fabric 5, the heat loss during the transmission process is reduced, and the drying efficiency is improved. In this process, the supporting strips 47 corresponding to the blowing pipe 45 support the non-woven fabric 5 to prevent the non-woven fabric 5 that is subjected to the concentrated heat at a close distance from being deformed under the action of wind force, and the exhaust holes on the supporting strips 47 are used for exhausting and dissipating heat.

[0036] And in this process, the conveying drive group 32 cooperates with the lifting and reciprocating group 49 to drive the blowing pipe 45 to move up and down to prevent certain areas of the non-woven fabric 5 from being overheated. The up and down movement can also disperse the heat distribution and reduce the generation of hot spots, thereby protecting the non-woven fabric 5 from heat damage. At the same time, it reduces the problem of local shrinkage or deformation of the non-woven fabric 5 caused by direct blowing of hot air, helps to maintain the flatness of the non-woven fabric 5, and the up and down reciprocating blowing can also help the hot air to fully dry the non-woven fabric 5, ensuring that the non-woven fabric 5 can be well dried.

[0037] See also Figure 1 , Figure 3 and Figure 4 The support guide group 43 includes a plurality of annular grooves 430 evenly arranged from top to bottom on the side wall of the conveying roller 31. Support columns 431 corresponding to the conveying rollers 31 are installed between the fixed top plate 30 and the fixed base 1. The support columns 431 are located between the conveying rollers 31 on both sides arranged along the length direction of the fixed plate 2. A support ring frame 432 rotatably sleeved on the annular groove 430 is fixedly installed on the support column 431. The support column 431 is connected to the conveying roller 31 through the support ring frame 432 to support the middle part of the conveying roller 31, thereby improving the stability of the conveying roller 31. The support column 431 is provided with a slot 433 at the end face of the plug-in frame 40 opposite to it, and the end of the plug-in frame 40 away from the fixed frame 42 connected to it is provided with a convex abutment bar 434 in a top view, and the convex section end of the abutment bar 434 has inclined surfaces on both sides arranged along its thickness direction to facilitate the insertion of the raised section of the abutment bar 434 into the slot 433, and the abutment bar 434 is plugged into and matched with the slot 433, so as to support the end of the plug-in frame 40 away from the fixed frame 42 connected to it, thereby preventing the plug-in frame 40 from being in a cantilever beam state and affecting the stability of the plug-in frame 40.

[0038] See also Figure 1 , Figure 2 and Figure 3 The sliding drive group 44 includes sliding seats 440 fixedly connected to the four corners of the fixed frame 42 by connecting blocks 441, and two sliding seats 440 opposite to each other are slidably connected to the adjacent fixed plate 2, and the sliding seat 440 slides through the fixed plate 2 close to the side of the adjacent fixed frame 42, and the sliding seat 440 extends along the length direction of the fixed plate 2. The two sliding seats 440 connected to one of the fixed frames 42 on the same fixed plate 2 are located between the two sliding seats 440 connected to the other fixed frame 42.

[0039] An external driving source (such as an electric slider) drives the sliding seat 440 to move, and the sliding seats 440 connected to the two fixed frames 42 respectively drive the two fixed frames 42 to move away from each other, and the fixed frames 42 drive the inserted frame 40 connected to it to move out from between the two adjacent conveying rollers 31, so as to facilitate the non-woven fabric 5 to be wrapped around multiple conveying rollers 31 in a wave shape in the initial state and to maintain the entire drying device.

[0040] After the non-woven fabric 5 is wound around the conveying roller 31, the sliding seats 440 on the two fixed frames 42 are driven by an external driving source to move the two fixed frames 42 toward the conveying roller 31, so that the insertion frame 40 is inserted between the corresponding two conveying rollers 31. At this time, both ends of the sliding seat 440 enter between the two fixed plates 2, which greatly reduces the space occupied by the drying device.

[0041] See also Figure 1 , Figure 2 and Figure 4 The blowing and drying air source group 48 includes a delivery pipe 480 which is connected and communicated with a plurality of blowing pipes 45 on the same rack 40 through a flexible pipe 481 in the middle. The delivery pipe 480 is fixedly connected to the corresponding rack 40 and the end of the delivery pipe 480 passes through the corresponding fixed frame 42. An electric heating wire (not shown) is arranged in the delivery pipe 480. An external air source device (such as a fan) is arranged on the fixed frame 42. The wind force delivered by the external air source device to the plurality of delivery pipes 480 gradually decreases from the side where the non-woven fabric 5 enters to the side where the non-woven fabric 5 exits, so as to reduce resource waste.

[0042] See also Figure 4 and Figure 7An arc box 401 is installed between two adjacent racks 40 connected with the blowing pipe 45 and is semi-wrapped on the conveying roller 31 therebetween. The arc box 401 is a hollow structure. An electric heating wire (not shown in the figure) is also installed in the arc box 401. The inner arc surface of the arc box 401 is also provided with evenly arranged blowing holes, and the corresponding conveying roller 31 is also provided with evenly arranged exhaust holes. A connecting pipe 402 is installed on the outer arc surface of the arc box 401. The connecting pipe 402 is connected to the conveying pipe 480 closest to the output side of the non-woven fabric 5 to prevent the blowing holes on the arc box 401 from blowing large hot air to the non-woven fabric 5, causing the non-woven fabric 5 to be locally overheated and deformed.

[0043] The air transported by the conveying pipe 480 into the arc box 401 forms hot air after passing through the electric heating wire, and the hot air is blown toward the non-woven fabric 5 through the blowing holes. The exhaust holes opened on the corresponding conveying roller 31 are used to exhaust air, thereby further blowing and drying the non-woven fabric 5 to improve the drying efficiency. Moreover, the non-woven fabric 5 will not be deformed due to the influence of the hot air under the support of the arc surface of the side wall of the conveying roller 31.

[0044] See also Figure 1 and Figure 6 The upper and lower ends of the rack 40 are provided with limiting grooves 403, and the fixed top plate 30 and the fixed base 1 are both provided with limiting blocks 404 corresponding to the limiting grooves 403, and the limiting blocks 404 are slidably connected with the limiting grooves 403, so as to support and limit the rack 40 during the horizontal sliding process of the rack 40. At the same time, when the rack 40 moves away from the conveying roller 31 opposite to it, the end of the rack 40 away from the fixed rack 42 connected thereto can still be supported by the cooperation of the limiting blocks 404 and the limiting grooves 403, thereby improving the stability of the rack 40.

[0045] See also Figure 4 and Figure 7 The inner arc surface of the arc box 401 is installed with plug rods 420 arranged symmetrically up and down, and the corresponding support ring frame 432 connected to the conveying roller 31 is provided with a plug hole, and the plug rod 420 is plugged into the plug hole, further improving the stability of the arc box 401 and the plug frame 40 connected thereto.

[0046] See also Figure 1 and Figure 6 The conveying drive group 32 includes a mounting groove 320 opened on the fixed base 1. The lower ends of multiple conveying rollers 31 located on the same straight line are inserted into the mounting groove 320 and are connected to the chain through a sprocket 321. The lower end of one of the conveying rollers 31 is connected to a rotating drive source (such as a motor, not shown in the figure) installed in the mounting groove 320.

[0047] The rotary driving source drives the conveying roller 31 connected thereto to rotate, and a plurality of conveying rollers 31 connected to the chain via the sprocket 321 rotate synchronously. The conveying roller 31 cooperates with the external traction device to convey the nonwoven fabric 5 during the rotation process.

[0048] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The lifting and reciprocating group 49 includes a connecting seat 490 symmetrically arranged up and down and connected to the side wall of a side of the multiple blowing tubes 45 away from the non-woven fabric 5, and a corresponding plug-in rack 40 is provided with a guide groove 491 slidably connected to the connecting seat 490, and the guide groove 491 and the connecting seat 490 are connected by evenly arranged return springs 492. An I-shaped frame 493 is installed at the bottom of the multiple blowing tubes 45 connected to the same plug-in rack 40, and a connecting groove 494 slidably connected to the I-shaped frame 493 and penetrating the mounting groove 320 is provided on the fixed base 1. A lifting linkage component is installed on the side of the mounting groove 320 close to the rotating drive source to drive the I-shaped frame 493 to move up and down when the conveying roller 31 rotates.

[0049] See also Figure 5 and Figure 6 The lifting linkage assembly includes a rotating shaft 410 rotatably connected in the mounting groove 320 through a torsion spring, a Z-shaped seesaw 411 corresponding to the I-shaped frame 493 is fixedly sleeved on the rotating shaft 410, a rotating disk 412 is fixedly sleeved on the conveying roller 31 connected to the sprocket 321, the rotating disk 412 is located above the sprocket 321, and wedge blocks 413 evenly arranged along its circumference are installed at the bottom of the rotating disk 412. The seesaw 411 is inclined, and one end of the seesaw 411 that is tilted downward is located below the rotating disk 412 and is rollingly connected to a ball bearing, and the other end of the seesaw 411 is rotatably connected to a lifting roller 414.

[0050] When the hot air blows and dries the non-woven fabric 5 through the blowing holes, the rotating driving source drives the conveying roller 31 connected thereto to rotate and convey the non-woven fabric 5. The plurality of conveying rollers 31 connected to the chain through the sprocket 321 rotate synchronously, and at the same time drive the rotating disk 412 thereon to rotate. During the rotation of the rotating disk 412, when the inclined surface of the wedge block 413 contacts the ball on the seesaw 411, the wedge block 413 presses down the seesaw 411, and the other end of the seesaw 411 moves upward and pushes the I-shaped frame 493 upward through the lifting roller 414. The I-shaped frame 493 drives the plurality of blowing pipes 45 and the connecting seat 490 to move upward. At this time, the connecting seat 490 pulls the reset spring 492 to stretch. When the wedge block 41 After the ball bearings on the seesaw 411 and the seesaw 411 are separated, the reset spring 492 pulls the connecting seat 490 to drive the blowing pipe 45 to move downward, and the I-shaped frame 493 resets as the blowing pipe 45 moves downward, and the multiple wedges 413 on the rotating disk 412 circulate in turn to contact with the ball bearings on the seesaw 411, so that the blowing pipe 45 can move up and down to blow the non-woven fabric 5, thereby expanding the blowing and drying range of the blowing holes on the blowing pipe 45 to the non-woven fabric 5, ensuring that all parts of the non-woven fabric 5 can be evenly heated and dried, avoiding the problem of local overheating or insufficient drying, and the up and down movement can disperse the heat distribution, reduce the generation of hot spots, and thus protect the non-woven fabric 5 from heat damage.

[0051] During operation, the blowing and drying air source conveys air to the blowing pipe 45, and the blowing pipe 45 blows and dries the non-woven fabric 5 through the blowing holes. During this process, the rotating driving source drives the conveying roller 31 connected thereto to rotate, and multiple conveying rollers 31 connected to the chain through the sprocket 321 rotate synchronously and convey the non-woven fabric 5. At the same time, the hot air is blown vertically to the non-woven fabric 5 through the blowing holes, and the hot air can be directly conveyed to the surface of the non-woven fabric 5, reducing the loss of heat during the transmission process and improving the drying efficiency. During this process, the supporting strips 47 corresponding to the blowing pipe 45 support the non-woven fabric 5 to prevent the non-woven fabric 5 that is subjected to concentrated heat at a close distance from being deformed under the action of wind force, and the exhaust holes on the supporting strips 47 are used for exhausting and dissipating heat.

[0052] When the rotary drive source drives the conveying roller 31 to rotate, the conveying roller 31 cooperates with the lifting and reciprocating group 49 to drive the blowing tube 45 to move back and forth up and down, preventing certain areas of the non-woven fabric 5 from being overheated, thereby protecting the non-woven fabric 5 from heat damage, and the up and down reciprocating blowing also helps the hot air to fully dry the non-woven fabric 5, ensuring that the non-woven fabric 5 can be well dried.
