Description

Technical Field

[0001] The present invention relates to a surface pressing device and method for non-woven fabric production, belonging to the technical field of non-woven fabric surface treatment. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., can be made into different thicknesses, handfeel, hardness, etc. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light, flame-retardant, non-toxic and odorless, low price, recyclable, etc. It can be used in different industries, such as sound insulation, heat insulation, heating sheets, masks, clothing, medical use, filling materials, etc., and is widely used. When producing non-woven fabric, through surface pressing, it makes the surface of the non-woven fabric arranged regularly or in a twill pattern to form unevenness, and this kind of non-woven fabric has a high water absorption rate.

[0003] For example, the publication number is: CN109825981A, a pattern embossing device for efficient non-woven fabric production, including a base, a cloth receiving shaft, a raw material shaft, an upper embossing roller, and a lower embossing roller. There are the cloth receiving shaft and the raw material shaft at both ends of the base. There is non-woven fabric outside the cloth receiving shaft. There is the lower embossing roller above the middle of the base, and there is the upper embossing roller above the lower embossing roller. There is an inflection point between the upper embossing roller and the cloth receiving shaft. There is a connecting rod between the inflection point and the base. There is a rear pressing rod on the side of the inflection point away from the connecting rod, and there is a rear tightening roller on the side of the rear pressing rod away from the inflection point. There is a front pressing rod between the upper embossing roller and the raw material shaft, and there is a front tightening roller on the side of the front pressing rod away from the inflection point. There is a driving device below the cloth receiving shaft. The beneficial effects are as follows: The present invention can automatically emboss non-woven fabric, with good embossing effect, fast embossing speed, little damage to non-woven fabric, can change the pattern shape according to production needs, has reasonable structure setting, and high production efficiency.

[0004] Another example is the publication number: CN113373643A, a pattern embossing device for efficient non-woven fabric production, related to the field of non-woven fabric production, including fixed side plates. The bottom surface of the fixed side plates is vertically welded with support vertical rods. The two ends of the fixed side plates are symmetrically welded with extension cross bars. The extension cross bars are provided with clamping grooves at the ends far from the fixed side plates. The inner sides of the clamping grooves are inserted with flipping rods. The two extension cross bars are horizontally butted with extension rods at the ends far from the fixed side plates. A feeding rod body is horizontally inserted between the extension rod and the extension cross bar. A transmission motor is bolted to the side of one of the extension cross bars. A fixed plate is horizontally welded between the fixed side plates. The device of the present invention has a simple structure and convenient operation. The adoption of the flipping structure design makes the feeding and replacement more simple and efficient. At the same time, the multiple support structures make the fabric flatter, which is beneficial to the integrity of the indentation and makes the indentation more beautiful.

[0005] However, during use, when surface pressing non-woven fabrics of different batches, different reticulate patterns or decorative patterns are required. When changing the patterns, the pressing rollers need to be replaced, which not only incurs a relatively high cost but also involves cumbersome operations, making it inconvenient to use and having poor applicability. Moreover, during processing, after hydroentangling and surface pressing, it is not convenient to perform subsequent processing, easily resulting in the disappearance of the pressed patterns and being inconvenient to use. Summary of the Invention

[0006] The object of the present invention is to solve the above problems by providing a surface pressing device and method for non-woven fabric production, which can facilitate the rapid replacement of the pressed patterns, facilitate operation and subsequent processing, improve the state of the patterns, and avoid disappearance.

[0007] The present invention achieves the above object through the following technical solutions. A surface pressing device and method for non-woven fabric production includes a main body component. The main body component includes a bottom plate. One side of the upper end of the bottom plate is rotatably installed with a feeding roller, and a dryer is fixedly installed on the other side of the upper surface of the bottom plate. The upper end of the bottom plate is fixedly installed with a frame component on one side of the feeding roller. The frame component includes a support frame, and a embossing component is rotatably placed above the inside of the support frame. The frame component drives the embossing component, and a post-treatment component is fixedly installed on one side of the upper surface of the bottom plate where the frame component is located. The post-treatment component is located between the frame component and the dryer. During use, the non-woven fabric is introduced into this technical solution through the feeding roller, and after passing through the embossing component, it is introduced into the post-treatment component. After being processed by the post-treatment component, it enters the inside of the dryer for drying treatment. When introducing and pulling out, a tensioning force is applied to the non-woven fabric, so that the non-woven fabric is pressed tightly against the embossing component. The frame component drives the embossing component to rotate slowly, so that when the non-woven fabric passes through the embossing component, reticulate patterns are formed on the non-woven fabric, which is convenient for operation and use. And when it is necessary to change the pattern of the reticulate pattern, the embossing component is removed from the frame component, and the pattern on the embossing component is changed, which is convenient for operation and convenient to use.

[0008] Preferably, in order to facilitate the installation of the feeding roller, brackets are fixedly installed at both ends of one side of the upper surface of the bottom plate, and the feeding roller is rotatably installed between the brackets. Through the brackets, it is convenient to install the feeding roller, and the height of the feeding roller is lower than the height of the embossing component, so that the non-woven fabric forms a V-shaped structure on both sides of the embossing component, which is convenient for embossing.

[0009] Preferably, for facilitating the clamping of the embossing assembly, a bayonet is provided on one side at the middle position of the support frame, and both ends of the embossing assembly are clamped inside the bayonet. Electric telescopic rods are fixedly installed on both sides at the upper end of the support frame, and a hydroentangling device is fixedly installed at the output end of the electric telescopic rod. The output end of the hydroentangling device is located above the embossing assembly. Through the bayonet, it is convenient to place the embossing assembly, enabling the embossing assembly to rotate inside the bayonet. Moreover, the hydroentangling device is pushed to rise and fall by the electric telescopic rod. When replacing the embossing assembly, the hydroentangling device rises. When processing the non-woven fabric, the output end of the hydroentangling device approaches the embossing assembly, facilitating the hydroentangling operation on the non-woven fabric and applying pressure to the non-woven fabric in the direction of the embossing assembly, further improving the embossing effect.

[0010] Preferably, for facilitating the driving of the embossing assembly, a drive shaft is rotatably installed between the lower ends of the support frame, and a reduction motor is fixedly installed at the middle position of the drive shaft. The reduction motor drives the drive shaft, and both ends of the drive shaft extend outside both ends of the support frame. Drive pulleys are fixedly installed at both ends of the drive shaft, a belt is sleeved on the drive pulley, and the belt is sleeved on both ends of the embossing assembly. When driving the embossing assembly, the drive shaft is driven to rotate by the reduction motor, thereby causing the drive pulley to rotate. Moreover, through the belt, it is convenient to drive the embossing assembly. When replacing the embossing assembly, the belt is disengaged from the embossing assembly, facilitating the removal of the embossing assembly. Moreover, during the embossing operation, the belt also applies a downward pulling force to the embossing assembly to prevent the embossing assembly from disengaging from the bayonet.

[0011] Preferably, for facilitating embossing, the embossing assembly includes an embossing shaft, and bearings are fixedly installed at both ends of the embossing shaft. The bearings are clamped inside the bayonet, and driven pulleys are fixedly installed at both ends of the embossing shaft. The belt is sleeved on the driven pulleys, and end plates are fixedly installed on the inner sides of both ends of the embossing shaft close to the bearings. An inflatable bag is fixedly installed on the outer side between the end plates, and the inside of the embossing shaft is a hollow structure. An air charging and discharging port is fixedly installed at one end of the embossing shaft, and the air charging and discharging port is communicated with the inside of the inflatable bag through the hollow structure inside the embossing shaft. Through the embossing shaft and the bearings, it is convenient to clamp the embossing shaft inside the bayonet, and through the driven pulleys, it is convenient to drive the embossing shaft to rotate on the bearings. And through the inflatable bag, high-pressure gas is filled into the inside of the inflatable bag through the air charging and discharging port, so as to provide sufficient hardness during embossing. And when changing the pattern, by deflating the inflatable bag, it is convenient to disassemble the reticulated sleeve, which is convenient for operation and replacement.

[0012] Preferably, for facilitating the formation of reticulations and the replacement of reticulation patterns, a reticulated sleeve is sleeved on the outer side of the inflatable bag, and connecting ears are fixedly installed at both ends of the reticulated sleeve in a circumferential array. Threaded holes are opened on the outer side of the end plate in a circumferential array, and fixing screws are threadedly connected to the connecting ears, and one end of the fixing screw is threadedly connected inside the threaded hole. Through the reticulated sleeve, it is convenient to replace the reticulation patterns during pressing. And after replacement, through the fixing screws, the reticulated sleeve is fixed between the end plates, and the inflatable bag provides hardness for the reticulated sleeve, so as to facilitate the embossing process.

[0013] Preferably, for facilitating the post-treatment of the embossed non-woven fabric, the post-treatment assembly includes a treatment tank, and a guide roller is rotatably installed at the lower end of the middle position inside the treatment tank. A driving gear is fixedly installed at one end of the guide roller. Stirring rollers are rotatably installed on both sides of the guide roller at the lower end inside the treatment tank. A driven gear is fixedly installed at one end of the stirring roller. The driven gear meshes with the driving gear, and stirring blades are uniformly fixedly installed on the stirring roller. By injecting a post-treatment liquid, such as a softener, into the treatment tank, when the non-woven fabric passes through the guide roller, it immerses into the post-treatment liquid, and through the driving gear and the driven gear, when the guide roller rotates, the stirring roller rotates, so that the stirring blades stir the post-treatment liquid inside the treatment tank, improving the effect of the post-treatment of the non-woven fabric.

[0014] Preferably, in order to facilitate the export of the non-woven fabric, fixing plates are fixedly installed at both ends of the upper side of the treatment box near the dryer. An outlet roller is rotatably installed on one side between the fixing plates, and a pressing roller is slidably clamped on the other side between the fixing plates. The pressing roller and the outlet roller are parallel to each other. Through the outlet roller, it is convenient to lead out the post-treated non-woven fabric and introduce it into the dryer for drying treatment.

[0015] Preferably, in order to facilitate the extrusion of the post-treatment agent remaining on the non-woven fabric, a chute is formed on the fixing plate, and a slider is slidably clamped inside the chute. The pressing roller is rotatably installed between the sliders, and springs are fixedly installed at the upper and lower ends of one side of the slider. The other ends of the springs are fixedly connected to one side inside the chute. By applying a thrust force to the slider through the spring, the pressing roller is moved towards the outlet roller, facilitating the extrusion of the led non-woven fabric to squeeze out the excess post-treatment solution on the non-woven fabric, which is convenient for recycling.

[0016] A pressing method for a surface pressing device for non-woven fabric production is as follows during pressing:

[0017] Step 1: Pass the non-woven fabric to be processed through the feed roller, the embossing sleeve, the guide roller, between the outlet roller and the pressing roller, and the dryer in sequence, and apply a tension force during feeding and discharging.

[0018] Step 2: Drive the drive shaft through the reduction motor, and drive the embossing shaft to rotate through the belt. Press patterns on the non-woven fabric through the embossing sleeve, and perform hydroentangling on the non-woven fabric through the hydroentangling device.

[0019] Step 3: Pour the post-treatment agent into the interior of the treatment box, and introduce the non-woven fabric after pressing and hydroentangling into the treatment agent through the guide roller for post-treatment. And through the outlet roller and the pressing roller, squeeze and pre-dry the treatment agent on the non-woven fabric led out from the treatment agent.

[0020] Step 4: Dry the treatment agent remaining on the non-woven fabric through the dryer to complete the surface pressing process.

[0021] Step 4: When it is necessary to replace the pressed pattern, take out the embossing assembly from the frame assembly, deflate the inflatable bag, disassemble the embossing sleeve from the end plate, replace the embossing sleeve, and after replacement, fill the interior of the inflatable bag with high-pressure gas to provide sufficient hardness for the embossing sleeve to perform surface pressing into patterns.

[0022] The beneficial effects of the present invention are as follows: When in use, the reticulated sleeve is supported by the inflatable bag to provide hardness, which facilitates the replacement of the reticulated sleeve during inflation and deflation, making the operation convenient, enabling the use of different required patterns, and through the hydroentangling device and the post-treatment component, after surface pressing, it is convenient to maintain the pattern, prevent it from disappearing, and improve the surface treatment effect.

When in use, the non-woven fabric is introduced into this technical solution through the feeding roller 102, and after passing through the embossing assembly 3, it is introduced into the post-treatment assembly 4. After being processed by the post-treatment assembly 4, it enters the inside of the dryer 103 for drying treatment. When introducing and pulling out, a tensioning force is applied to the non-woven fabric, so that the non-woven fabric is pressed tightly on the embossing assembly 3. The frame assembly 2 drives the embossing assembly 3 to rotate slowly, so that when the non-woven fabric passes through the embossing assembly 3, a mesh pattern is formed on the non-woven fabric, which is convenient for operation and use. And when it is necessary to change the pattern of the mesh pattern, the embossing assembly 3 is removed from the frame assembly 2, and the pattern on the embossing assembly 3 is changed, which is convenient for operation and use.

And through the belt 208, it is convenient to drive the embossing assembly 3. When replacing the embossing assembly 3, the belt 208 is disengaged from the embossing assembly 3, which is convenient for taking out the embossing assembly 3. And during the embossing operation, the belt 208 also applies a downward pulling force to the embossing assembly 3 to prevent the embossing assembly 3 from disengaging from the bayonet 202.

[0038] As Figure 6 and Figure 7As shown, the embossing assembly 3 includes an embossing shaft 301, and bearings 302 are fixedly installed at both ends of the embossing shaft 301. The bearings 302 are clamped inside the bayonet 202. Driven pulleys 303 are fixedly installed at both ends of the embossing shaft 301. The belt 208 is sleeved on the driven pulleys 303.
