[0002] Spunbond non-woven fabric printing is a process of transferring patterns, texts or logos to the surface of spunbond non-woven fabric through printing technology, which is widely used in fields such as packaging, advertising, medical treatment, and agriculture. Spunbond non-woven fabric has good strength and uniformity, is suitable for various printing processes, can improve waterproof and barrier properties through film laminating treatment, endows products with aesthetic appearance and information transmission functions after printing, and has lower printing costs and higher production efficiency compared with traditional materials.

[0003] Common spunbond non-woven fabrics need to be dried after printing to avoid ink bleeding and migration caused by the air permeability or friction of the non-woven fabric. In the actual drying process, the traditional hot air drying has a long drying time and low drying efficiency, and the hot air radiation range is fixed, which easily causes uneven drying of each part and affects the drying effect of non-woven fabric printing. Therefore, we provide a drying device for printing spunbond non-woven fabric based on film laminating production and processing to solve the above technical problems. Summary of the Invention

[0012] The present invention has the following beneficial effects: 1. By providing a winding component, the driving bevel gear rotates to drive the first bevel gear and the second bevel gear to rotate synchronously and in opposite directions, so that the two arc-shaped clamping plates move synchronously and in opposite directions, clamping and releasing the end of the non-woven fabric. As the hollow winding drum rotates, the non-woven fabric is wound around the circumferential side surface of the hollow winding drum and drives the non-woven fabric to move, thereby realizing the position limitation of the non-woven fabric and the timely collection and treatment of the printed and dried non-woven fabric.

[0013] 2. By providing a drying mechanism, when the piston plate moves downward, the air suction support frame body is in a closed state, the air outlet support frame body is opened, the gas passes through the first metal heat conduction tube, and the hot air is blown out from above the non-woven fabric. When the piston plate moves upward, the air suction support frame body is in an open state, the air outlet support frame body is closed, the gas passes through the non-woven fabric, and the non-woven fabric is further dried, thereby realizing the circulating flow of the hot air and improving the drying efficiency of the printed non-woven fabric.

[0014] 3. By providing a steering component, during the movement of the non-woven fabric, the second drive wheel drives the drive slideway to rotate, so that the drive trapezoidal block moves up and down reciprocally, and then drives the drive trapezoidal block to move horizontally reciprocally. Under the sliding fit of the drive slideway and the corresponding first drive column, the drive connecting rod rotates, and then drives the steering fan blades to swing reciprocally, thereby adjusting the preliminary drying operation after printing, and at the same time avoiding the fixed radiation range of the drying hot air, resulting in uneven drying and affecting the subsequent drying effect.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] For the first specific embodiment, please refer to Figures 1-14 , the present invention is a drying device for printing of spunbond non-woven fabric based on lamination production and processing, including a winding assembly 1. Specifically, the winding assembly 1 includes a rotatably arranged hollow winding drum 101. A limiting port 102 is provided on the circumferential side of the hollow winding drum 101. Two arc-shaped slideways are symmetrically arranged inside the hollow winding drum 101. An arc-shaped clamping plate 103 is slidably arranged inside the arc-shaped slideway. The clamping end of the arc-shaped clamping plate 103 is made of elastic material, which is convenient for clamping and restricting the end of the non-woven fabric.

[0033] Further, a drying mechanism is fixedly arranged on one side of the hollow winding drum 101. The drying mechanism includes a drying support assembly 2, and the drying support assembly 2 includes a fixedly arranged drying support frame body 201. A plurality of air suction drying cylinders 202 are symmetrically and fixedly connected inside the drying support frame body 201. A drying adjustment assembly 3 is slidably arranged inside the drying support assembly 2. The drying adjustment assembly 3 includes an air suction support frame body 301 and an air outlet support frame body 302 corresponding to the air suction drying cylinders 202 one by one. The air suction support frame body 301 is fixedly connected to the corresponding air suction drying cylinder 202 through a telescopic hose 4. The printed non-woven fabric passes through the gap between the drying support assembly 2 and the drying adjustment assembly 3 for drying treatment.

[0034] Further, a direction adjustment assembly 5 is fixedly connected to one side surface of the drying adjustment assembly 3. The drying adjustment assembly 3 includes a direction adjustment support frame body 501 fixedly connected to the drying adjustment assembly 3. A plurality of direction adjustment fan blades 502 are rotatably connected inside the direction adjustment support frame body 501 through a direction adjustment rotating shaft.

[0035] The operation process of this embodiment is as follows: The non-woven fabric passes through the gap between the drying support assembly 2 and the drying adjustment assembly 3, and one end of the non-woven fabric is inserted into the limiting port 102. Control the two arc-shaped clamping plates 103 to slide along the inner part of the arc-shaped slideway until the two arc-shaped clamping plates 103 are both in close contact with the non-woven fabric, so as to realize the position limitation of the end part of the non-woven fabric. Control the hollow winding drum 101 to rotate to realize the winding of the non-woven fabric; during the movement of the non-woven fabric, when the air outlet support frame body 302 performs an air outlet operation, part of the gas flows to the direction adjustment assembly 5 and flows to the just-printed non-woven fabric through the direction adjustment support frame body 501. During the reciprocating swing of the direction adjustment fan blades 502, the flow direction of the hot air is adjusted to keep the drying of each part of the non-woven fabric uniform, so as to perform a preliminary drying treatment on the printed non-woven fabric. At the same time, when the air outlet support frame body 302 performs an air outlet operation, the air suction support frame body 301 is in a closed state, and another part of the hot air is blown out from above the non-woven fabric to dry the non-woven fabric; when the air outlet support frame body 302 is in a closed state, the air suction support frame body 301 performs an air suction operation, and the hot air flows through the air suction drying cylinder 202 to the telescopic hose 4 and is sucked into the air suction support frame body 301, so as to accelerate the flow of the hot air, make the hot air pass through the non-woven fabric, and further dry the non-woven fabric. The dried non-woven fabric is wound around the circumferential side surface of the hollow winding drum 101 as the hollow winding drum 101 rotates.

[0036] Specific Embodiment 2, please refer to Figures 2-6, on the basis of the first specific embodiment, specifically, the winding assembly 1 further includes two symmetrically and fixedly arranged winding support plates. One side surface of the winding support plate is fixedly connected with a semi-circular hollow frame 104. The surface of the semi-circular hollow frame 104 is rotatably connected with a semi-circular limiting frame, and the semi-circular limiting frame is in clamping fit with the semi-circular hollow frame 104. Opposite side surfaces of the hollow winding drum 101 are fixedly connected with first rotating shafts. One end of each first rotating shaft is fixedly connected with a clamping disc 105 that is slidably matched with the semi-circular hollow frame 104. The two clamping discs 105 are placed inside the corresponding semi-circular hollow frames 104, so that the hollow winding drum 101 is located between the continuous winding support plates, facilitating winding; after winding, the hollow winding drum 101 is lifted to make the clamping discs 105 disengage from the semi-circular hollow frames 104, facilitating the removal of the wound non-woven fabric. Moreover, the circumferential side surface of the first rotating shaft is fixedly connected with a transmission gear 106, and a second rotating shaft is fixedly connected between the two winding support plates. Two driving gears 107 are symmetrically and fixedly connected to the circumferential side surface of the second rotating shaft. One side surface of one of the winding support plates is fixedly installed with a first driving motor. The output shaft of the first driving motor is fixedly connected to the second rotating shaft, and the driving gear 107 is meshed with the corresponding transmission gear 106.

[0037] An arc-shaped clamping plate 103 is externally exposed. The circumferential side surface of the hollow winding drum 101 is fixedly connected with an arc-shaped rack 108. The arc-shaped rack 108 is slidably matched with the adjacent arc-shaped clamping plate 103. One side surface of the hollow winding drum 101 is fixedly connected with a driving support frame. One side surface of the driving support frame is rotatably provided with a first bevel gear 109. One side surface of the first bevel gear 109 is fixedly connected with a first adjusting gear 110 through a supporting horizontal shaft. The first adjusting gear 110 is meshed with one of the arc-shaped racks 108.

[0038] Furthermore, the other side surface of the driving support frame is rotatably connected with a second bevel gear 111 through an extending support plate. One side surface of the driving support frame close to the extending support plate is rotatably connected with a driving bevel gear 112. The driving bevel gear 112 is located between the first bevel gear 109 and the second bevel gear 111. A second driving motor is fixedly installed on the driving support frame. The output shaft of the second driving motor is fixedly connected to the driving bevel gear 112. The second driving motor belongs to a micro motor and can be powered by a battery. The battery is installed on the driving support frame to avoid wire winding during the non-woven fabric winding process. The driving bevel gear 112 is meshed with the first bevel gear 109 and the second bevel gear 111. One side surface of the second bevel gear 111 is fixedly connected with a second adjusting gear 113 through a hollow horizontal shaft. The hollow horizontal shaft and the supporting horizontal shaft are coaxially arranged. The second adjusting gear 113 is meshed with the other arc-shaped rack 108. One side surface of one of the winding support plates is rotatably provided with a first transmission wheel 114. The first transmission wheel 114 is fixedly connected to the second rotating shaft.

[0039] The operation process of this embodiment is as follows: Place the two engaging discs 105 inside the corresponding semi-circular hollow frames 104. Rotate the semi-circular limiting frames, and the semi-circular limiting frames engage with the corresponding semi-circular hollow frames 104 to limit the engaging discs, preventing the engaging discs from shifting when rotating, so that the hollow winding drum 101 is located between the continuous winding support plates. The driving gear 107 meshes with the corresponding transmission gear 106. When clamping and limiting the end of the non-woven fabric, insert the end of the non-woven fabric into the limiting port 102. Start the second driving motor to drive the driving bevel gear 112 to rotate. Under the meshing action of the driving bevel gear 112 with the first bevel gear 109 and the second bevel gear 111, the first bevel gear 109 and the second bevel gear 111 rotate synchronously in opposite directions. Under the connection action of the support horizontal shaft and the hollow horizontal shaft, drive the first adjusting gear 110 and the second adjusting gear 113 to rotate synchronously in opposite directions. Under the meshing action of the first adjusting gear 110 with one of the arc-shaped racks 108 and the second adjusting gear 113 with the other arc-shaped rack 108, drive the two arc-shaped clamping plates 103 to slide inside the arc-shaped slideways. The two arc-shaped clamping plates 103 move synchronously in opposite directions and approach each other until both arc-shaped clamping plates 103 are in close contact with the non-woven fabric, thereby realizing the position limitation of the end of the non-woven fabric. During the printing and drying process of the non-woven fabric, start the first driving motor to drive the second rotating shaft to rotate, and the two driving gears 107 rotate synchronously. Under the meshing action of the driving gear 107 with the corresponding transmission gear 106, the transmission gear 106 rotates, and then drives the hollow winding drum 101 to rotate, thereby winding the printed and dried non-woven fabric around the circumferential surface of the hollow winding drum 101. When the winding is completed, take out the hollow winding drum 101, so that the engaging disc 105 disengages from the semi-circular hollow frame 104. The second driving motor drives the driving bevel gear 112 to rotate in the reverse direction, so that the two arc-shaped clamping plates 103 move synchronously in opposite directions and move away from each other, canceling the clamping and limiting effect on the end of the non-woven fabric, which is convenient for removing the wound non-woven fabric from the circumferential surface of the hollow winding drum 101.

The inclined sliding surface of the driving trapezoidal block 509 is inclined downward gradually towards the direction away from the steering support frame 501 (as Figure 13 shown). The driving trapezoidal block 509 is slidably matched with the transmission trapezoidal block 508. A second transmission column 510 is fixedly connected to one side surface of the driving trapezoidal block 509. A driving slideway slidably matched with the second transmission column 510 is rotatably connected to the side surface of the steering support frame 501 close to the driving trapezoidal block 509 through an L-shaped support plate. A second transmission wheel 512 is rotatably arranged on one side surface of the L-shaped support plate. The second transmission wheel 512 is fixedly connected to the driving slideway. A feeding support is fixedly arranged on the side of the steering support frame 501 away from the adjustment support frame 303. Two support rollers 513 are symmetrically rotatably connected between the opposite inner side walls of the feeding support. The second transmission wheel 512 is connected to the first transmission wheel 114 through a transmission belt. The feeding support is fixedly connected with a printing device 514. The printing device 514 is located between the two support rollers 513.

[0045] The operation process of this embodiment is as follows: Pass the non-woven fabric through the gap between the adjustment support frame 303 and the drying support frame 201, and clamp and fix the end of the non-woven fabric through the arc-shaped clamping plate 103. According to the thickness of the non-woven fabric, start the electric telescopic rod 203 to drive the adjustment support frame 303 to slide along the drying support frame 201, thereby adjusting the distance between the first metal heat conduction tube 305 and the non-woven fabric, facilitating the adjustment of the heating height of non-woven fabrics with different heating requirements. The hollow winding drum 101 rotates to drive the non-woven fabric to move, and the non-woven fabric moves above the two support rollers 513. At the same time, the printing device 514 performs printing operations on the non-woven fabric.

[0046] During the movement of the non-woven fabric, the third driving motor is started to drive the transmission screw 314 to rotate. Under the screw-thread engagement between the transmission screw 314 and the linkage support plate 313, the linkage support plate 313 moves downward, and the piston rod 312 moves downward synchronously, thereby driving the piston plate 311 to slide downward along the inner wall of the sealing support frame 310, causing the air outlet valve plate 306 to rotate away from the through hole on the air outlet support frame body 302 under the thrust, so that the air outlet support frame body 302 is communicated with the first support frame 307, the air outlet support frame body 302 is opened, and the gas inside the sealing support frame 310 performs the air outlet operation through the air outlet support frame body 302. And the air inlet valve plate 308 rotates close to the air inlet support frame body 301 synchronously under the thrust and closely adheres to the upper surface of the air inlet support frame body 301, and the air inlet support frame body 301 is in a closed state. When the air outlet support frame body 302 performs the air outlet operation, part of the gas flows to the direction-adjusting assembly 5 and flows to the just-printed non-woven fabric through the direction-adjusting support frame body 501. The gas is heated by the energized second metal heat-conducting tube 315. At the same time, during the movement of the non-woven fabric, the second rotating shaft rotates to drive the first transmission wheel 114 to rotate. Under the connection of the transmission belt, the second transmission wheel 512 rotates synchronously, thereby driving the driving slideway 511 to rotate synchronously. Under the sliding fit between the driving slideway 511 and the second transmission column 510, the second transmission column 510 moves up and down reciprocally. The driving trapezoidal block 509 is driven to move up and down synchronously by the second transmission column 510. When the driving trapezoidal block 509 moves upward, under the sliding fit between the driving trapezoidal block 509 and the transmission trapezoidal block 508, the transmission trapezoidal block 508 moves horizontally away from the direction-adjusting support frame body 501. Under the connection of the extension bracket, the direction-adjusting transmission plate 506 moves horizontally synchronously. The transmission slideway 507 moves synchronously with the direction-adjusting transmission plate 506. Under the sliding fit between the transmission slideway 507 and the corresponding first transmission column 504, the first transmission column 504 moves, thereby driving the transmission connecting rod 503 to rotate, and driving the direction-adjusting fan blade 502 to rotate synchronously through the direction-adjusting rotating shaft; when the driving trapezoidal block 509 moves downward, the transmission trapezoidal block 508 moves horizontally close to the direction-adjusting support frame body 501, and the direction-adjusting transmission plate 506 moves horizontally in the reverse direction. Under the sliding fit between the transmission slideway 507 and the corresponding first transmission column 504, the first transmission column 504 moves in the reverse direction, thereby driving the transmission connecting rod 503 to rotate in the reverse direction, and driving the direction-adjusting fan blade 502 to rotate synchronously in the reverse direction. In this way, the reciprocating swing of the direction-adjusting fan blade 502 is realized. During the reciprocating swing of the direction-adjusting fan blade 502, the flow direction of the hot air is adjusted to keep each part of the non-woven fabric dry evenly, so as to perform the preliminary drying treatment on the printed non-woven fabric.

[0047] When the air outlet support frame 302 performs the air outlet operation, since the air inlet support frame 301 is in a closed state, part of the gas is discharged through the air-permeable support plate 304. The gas passes through the energized first metal heat conduction tube 305 for heating, so that the hot air is blown out from above the non-woven fabric and the non-woven fabric is dried.

[0048] The third driving motor drives the transmission screw 314 to rotate in the reverse direction. The linkage support plate 313 drives the piston plate 311 to slide upward along the inner wall of the sealing support frame 310 through the piston rod 312, so that the air outlet valve plate 306 rotates close to the air outlet support frame 302 under suction. The air outlet valve plate 306 is in close contact with the inner top of the air outlet support frame 302, and the air outlet support frame 302 is in a closed state. Moreover, the air inlet valve plate 308 rotates away from the air inlet support frame 301 synchronously under suction, and the air inlet support frame 301 is in an open state. The air inlet drying cylinder 202 absorbs the gas, accelerates the flow of the hot air above the non-woven fabric, so that the hot air passes through the non-woven fabric. The hot air flows through the telescopic hose 4 to the air inlet support frame 301 and then enters the inside of the sealing support frame 310, so as to further dry the non-woven fabric. The dried non-woven fabric is wound around the circumferential side surface of the hollow winding drum 101 as the hollow winding drum 101 rotates.
