Description

Technical Field

[0001] The present application relates to the technical field of non-woven fabric production, and in particular to a laminating device for non-woven fabric production. Background Art

[0002] When making non-woven fabrics, short fibers or filaments are used to form a web through airflow or mechanical means, and then heat-bonded to strengthen them. This special production process gives non-woven fabrics many unique characteristics. In the production process of non-woven fabrics, the last step is to arrange them into rolls. In this process, hot rolling is usually used for lamination. This is because hot rolling can make the surface of non-woven fabrics smoother and improve their overall texture. However, before non-woven fabrics are pressed, they are usually stored in rolls. This method can effectively protect non-woven fabrics and prevent them from being damaged during storage and transportation.

[0003] However, when the fabric roll is stored, wrinkles may appear due to the previous process of winding. These wrinkles are formed due to the pressure on the non-woven fabric during the winding process. When the non-woven fabric is rolled and squeezed layer by layer, these wrinkles gradually form creases. These creases are difficult to eliminate by tension control when the non-woven fabric is pressed. The creases are deeply embedded in the structure of the non-woven fabric and cannot be eliminated by simple tension control, which will affect the final pressing quality of the non-woven fabric. When the non-woven fabric is pressed, the creases may cause the surface of the non-woven fabric to be uneven, affecting its overall texture and aesthetics.

[0004] Referring to the Chinese patent application document with publication number CN117183547A, whose subject name is production equipment for composite non-woven fabrics and production process for composite non-woven fabrics, the patent unfolds the creases on the surface of the non-woven fabric and uses an adaptive pressing system to press the non-woven fabric after the creases are unfolded.

[0005] According to the above technical scheme, in the process of unfolding the creases in the non-woven fabric, since the non-woven fabric is a porous material composed of short fibers or long fibers bonded by physical or chemical methods, if it is subjected to uneven or excessive pulling force during the lamination process, it may cause the fiber structure to deform or break, thereby affecting the overall strength or performance of the non-woven fabric. At the same time, in the process of laminating the non-woven fabric, it is necessary to further adjust the unfolded non-woven fabric to reduce the problem of uneven surface thickness of the non-woven fabric after lamination due to different elongation of the non-woven fabric during the lamination of multiple layers of non-woven fabrics. Summary of the invention

[0006] In view of this, the present application provides a laminating device for non-woven fabric production, which can reduce the problem of deformation or breakage of non-woven fabric.

[0007] A laminating device for non-woven fabric production provided in the present application adopts the following technical scheme, including a display frame, a heat sealing machine arranged at the discharge of the display frame, and a cloth placing roller located at the feed of the display frame; a rotating block is rotatably connected to the top of the display frame, and connecting blocks are fixedly connected to both ends of the rotating block. A rotating roller is hingedly connected to the side of the connecting block facing the inside of the display frame, which is used to maintain the tension of the non-woven fabric when the non-woven fabric is unfolded; an unfolding roller is rotatably connected to the display frame, and a longitudinal unfolding block that can abut against the non-woven fabric is arranged below the unfolding roller, and a tensioning wheel is hingedly connected to the longitudinal unfolding block, and the tensioning wheel and the longitudinal unfolding block are connected by a clockwork spring, which is used to pull the tensioning wheel to rotate.

[0008] The folds parallel to the conveying direction of the non-woven fabric are unfolded by the relative movement of the rotating block, and the folds perpendicular to the conveying direction of the non-woven fabric are unfolded by the longitudinal unfolding block. The unfolded non-woven fabric is further adjusted by the rotating block, so that the surface thickness of the non-woven fabric remains uniform to a certain extent during the lamination process.

[0009] Optionally, the display frame is provided with an adjustment mechanism for adjusting the upward or downward movement of the rotating rollers at both ends of the lever structure.

[0010] Optionally, the adjustment mechanism includes a connecting plate, and two connecting plates are provided, the connecting plates are slidably connected to the middle position of the display rack, the connecting plates are slidably connected with a shaping plate, the shaping plate and the connecting plates are slidably connected via a spring, and a jack mechanism is provided under the connecting plates for pushing the connecting plates to rise or fall.

[0011] After the wrinkles on the surface of the non-woven fabric are unfolded, the non-woven fabric needs to be heated. During the heating process, the jack mechanism unfolds to both ends, pushing the connecting plate to move upward. The upward movement of the connecting plate drives the shaping plate to move upward, so that the shaping plate fixes the heated non-woven fabric on the unfolding roller for a period of time, so that the non-woven fabric can be better shaped.

[0012] Optionally, the connecting plate is fixedly connected with an adjusting rod toward the upper end of the display frame, the adjusting rod is provided with an adjusting rack, a rotating gear is fixedly connected with the connection between the rotating block and the display frame, the adjusting rack can mesh with the rotating gear, and drive the rotating rod block to rotate to a certain extent.

[0013] During the heating process of the non-woven fabric, the connecting plate moves upward, driving the adjusting rack on the adjusting rod to move, causing the rotating gear to drive the rotating block to rotate, so that the non-woven fabric moves to a certain extent, and moves the non-woven fabric in the next section toward the unfolding roller.

[0014] Optionally, a clamping strip is rotatably connected to the connecting plate, and a clamping groove is provided on the shaping plate. When the connecting plate moves upward, the clamping strip can be fixed to the clamping groove, thereby driving the shaping plate to move downward.

[0015] When the connecting plate moves upward, the clamping strip is driven to move upward, so that the clamping strip abuts against and is fixed to the clamping groove, and when the connecting plate moves downward, the shaping plate is driven to move downward, thereby facilitating the reuse of the shaping plate.

[0016] Optionally, a rotating motor is fixedly connected to the central axis of the display frame, and the rotating motor is used to drive the jack mechanism to unfold to both ends.

[0017] When the jack mechanism needs to be used to expand toward both ends, the rotating motor is started to drive the jack mechanism threadedly connected to the output shaft of the rotating motor to expand toward both ends.

[0018] Optionally, the two connecting plates are symmetrically arranged relative to the rotating motor.

[0019] Optionally, the end of the clamping strip away from the clamping groove is provided with an abutment block which rotates around its own hinge when the two connecting plates are relatively close to each other.

[0020] When the connecting plates need to be recovered, the rotating motor drives the two ends of the jack mechanism closer together to recover the two connecting plates. During the recovery process, the clamping strips provided on the two connecting plates are relatively close to and abut against each other, and then rotate after abutting to loosen the fixation of the shaping plates, so as to facilitate use during the next shaping.

[0021] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Eliminating the wrinkles perpendicular to the moving direction of the non-woven fabric and the wrinkles parallel to the moving direction of the non-woven fabric can increase the heat-sealing strength of the non-woven fabric and reduce the impact of the heat-sealing effect and strength due to the uneven heat-sealing area. At the same time, a lever structure is used to maintain appropriate tension in various parts of the non-woven fabric and keep the tension relatively consistent. To a certain extent, it ensures that the non-woven fabric contacts the heating element evenly during the heat-sealing process, thereby achieving a uniform heat-sealing effect and improving the strength and sealing during heat-sealing.

[0023] 2. Fixing the non-woven fabric during heating can ensure that the non-woven fabric can be evenly heated, thereby achieving a uniform processing effect. At the same time, the non-woven fabric can be kept in a relatively fixed position during heating, reducing friction on the surface of the non-woven fabric.

[0024] 3. By adjusting the rotation angle of the rotating block, the insufficient tension of the non-woven fabric during movement can be reduced, the probability of uneven pulling force of the non-woven fabric during the lamination process can be reduced, and the overall strength and performance of the non-woven fabric can be enhanced.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 5 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0032] Reference Figure 1 , Figure 2 and Figure 4The present embodiment provides a laminating device for producing non-woven fabrics, comprising a display frame 1 placed on a horizontal plane, a heat sealing machine 2 for compounding the non-woven fabrics is arranged at the discharge of the display frame 1, two cloth placing rollers 3 for feeding the display frame 1 are arranged in the vertical direction at the feed of the display frame 1, a rotating block 4 is rotatably connected to the display frame 1, connecting blocks 41 are fixedly connected at both ends of the rotating block 4, a rotating roller 42 is hingedly connected to one side of the connecting block 41 facing the inside of the display frame 1, and is used to maintain the tension on the non-woven fabric when the non-woven fabric is unfolded, an unfolding roller 5 is rotatably connected to the display frame 1, and the unfolding roller 5 is used to unfold the wrinkles of the non-woven fabric in the conveying direction, and a longitudinal unfolding block 51 that can abut against the non-woven fabric is arranged at a position below the unfolding roller 5, and a tensioning wheel 52 is hingedly connected to the longitudinal unfolding block 51, and the tensioning wheel 52 is connected to the longitudinal unfolding block 51 through a clockwork spring, which is used to pull the tensioning wheel 52 to rotate and unfold the wrinkles on the non-woven fabric perpendicular to the conveying direction.

[0033] The display stand 1 is placed on a horizontal plane, and a cloth placing roller 3 is placed at the feeding position of the display stand 1, and the cloth on the cloth placing roller 3 is wound around the rotating roller 42 on the rotating block 4, and is wound around the unwinding roller 5. In the process of the non-woven fabric moving toward the heat sealing machine 2, the rotating block 4 rotates to drive the connecting block 41 to move, so that the rotating roller 42 on the connecting block 41 near the cloth placing roller 3 moves downward, so that the tension on the non-woven fabric in the interval between the cloth placing roller 3 and the unwinding roller 5 is reduced, and at this time, the connecting block 41 located on the side close to the heat sealing machine 2 moves upward, and drives the rotating roller 42 to move upward. The non-woven fabric located in the area between the heat sealing machine 2 and the rotating roller 42 is moved, and the tension on the non-woven fabric located on the unfolding roller 5 is increased, so that the wrinkles of the non-woven fabric parallel to the moving direction are unfolded. At the same time, a heating wire is arranged inside the unfolding roller 5 to iron the wrinkles. The longitudinal unfolding block 51 is close to the unfolding roller 5 and abuts against the surface of the non-woven fabric away from the unfolding roller 5. At this time, the clockwork spring drives the tensioning wheel 52 to rotate, so that the tensioning wheel 52 unfolds the wrinkles perpendicular to the moving direction of the fabric and eliminates the wrinkles when the unfolding roller 5 irons the non-woven fabric.

[0034] Eliminating wrinkles perpendicular to the moving direction of the non-woven fabric and wrinkles parallel to the moving direction of the non-woven fabric can increase the heat-sealing strength of the non-woven fabric and reduce the impact of uneven heat-sealing areas on the heat-sealing effect and strength. At the same time, a lever structure is used to maintain appropriate tension in various parts of the non-woven fabric and keep the tension relatively consistent, which to a certain extent ensures that the non-woven fabric is in uniform contact with the heating element during the heat-sealing process, thereby achieving a uniform heat-sealing effect and improving the strength and sealing during heat-sealing.

[0035] Reference Figure 1 and Figure 2The display rack 1 is provided with an adjustment mechanism 6, which is used to adjust the upward or downward movement of the rotating rollers 42 at both ends of the rotating block 4. The adjustment mechanism 6 includes a connecting plate 61, and two connecting plates 61 are provided. The connecting plates 61 are slidably connected to the middle position of the display rack 1. The connecting plates 61 are slidably connected with a shaping plate 62. The shaping plate 62 and the connecting plate 61 are slidably connected through a spring. A jack mechanism 63 is provided below the connecting plate 61 to push the connecting plate 61 to rise or fall.

[0036] After the wrinkles on the surface of the non-woven fabric are unfolded, the non-woven fabric needs to be heated. During the heating process, the jack mechanism 63 unfolds to both ends, pushing the connecting plate 61 to move upward. The upward movement of the connecting plate 61 drives the shaping plate 62 to move upward, so that the shaping plate 62 fixes the non-woven fabric that is heated on the unfolding roller 5 for a period of time, so that the non-woven fabric can be better shaped.

[0037] Fixing the nonwoven fabric during heating can ensure that the nonwoven fabric can be heated evenly, thereby achieving a uniform processing effect. At the same time, it can keep the position of the nonwoven fabric relatively fixed during heating, reducing friction on the surface of the nonwoven fabric.

[0038] Reference Figure 2 and Figure 5 The connecting plate 61 is fixedly connected with an adjusting rod 7 toward the upper end of the display frame 1. The adjusting rod 7 is provided with an adjusting rack 71. A rotating gear 72 is fixedly connected with the connection between the rotating block 4 and the display frame 1. The adjusting rack 71 can mesh with the rotating gear 72 to drive the rotating block 4 to rotate to a certain extent.

[0039] During the heating process of the non-woven fabric, the connecting plate 61 moves upward, driving the adjusting rack 71 on the adjusting rod 7 to move, causing the rotating gear 72 to drive the rotating block 4 to rotate, so that the non-woven fabric moves to a certain extent, and moves the non-woven fabric in the next interval toward the unfolding roller 5.

[0040] By adjusting the rotation angle of the rotating block 4, the situation of insufficient tension of the non-woven fabric during movement can be reduced, the probability of uneven pulling force of the non-woven fabric during the lamination process can be reduced, and the overall strength and performance of the non-woven fabric can be enhanced.

[0041] Reference Figure 3 The connecting plate 61 is rotatably connected with a clamping strip 8, and a clamping groove 81 is provided on the shaping plate 62. When the connecting plate 61 moves upward, the clamping strip 8 can be fixed with the clamping groove 81, driving the shaping plate 62 to move downward.

[0042] When the connecting plate 61 moves upward, it drives the clamping strip upward, so that the clamping strip 8 abuts and fixes with the clamping groove 81 , and when the connecting plate 61 moves downward, it drives the shaping plate 62 downward, which facilitates the reuse of the shaping plate 62 .

[0043] Reference Figure 1 A rotating motor 9 is fixedly connected to the central axis of the display frame 1 . The rotating motor 9 is used to drive the jack mechanism 63 to expand to both ends, and the two connecting plates 61 are symmetrically arranged relative to the rotating motor 9 .

[0044] When the jack mechanism 63 needs to be used to expand toward both ends, the rotary motor 9 is started to drive the jack mechanism 63 threadedly connected to the output shaft of the rotary motor 9 to expand toward both ends.

[0045] Reference Figure 3 The end of the clamping strip 8 away from the clamping groove 81 is provided with an abutment block 82 that rotates around its own hinge when the two connecting plates 61 are relatively close. When the connecting plates 61 need to be recovered, the rotating motor 9 drives the two ends of the jack mechanism 63 to approach each other to recover the two connecting plates 61. During the recovery process, the clamping strips 8 provided on the two connecting plates 61 are relatively close and abut against each other, and rotate after abutting to loosen the fixation of the shaping plate 62, so as to facilitate the use of the shaping next time.

[0046] The implementation principle of a non-woven fabric production lamination device in the embodiment of the present application is:

[0047] The display rack 1 is placed on a horizontal plane, and a cloth placing roller 3 is placed at the feeding position of the display rack 1. The cloth on the cloth placing roller 3 is wound around the rotating roller 42 located on the rotating block 4, and is wound around the unwinding roller 5. The rotating motor 9 drives the jack mechanism 63 to unwind toward both ends, and the connecting plates 61 fixedly connected at both ends of the jack mechanism 63 are moved toward the unwinding roller 5. During the movement, the spring pushes the shaping plate 62 to move toward the side close to the unwinding roller 5.

[0048] The rotation of the rotating block 4 drives the connecting block 41 to move, so that the rotating roller 42 on the connecting block 41 near the cloth placing roller 3 moves downward, so that the tension on the non-woven fabric in the interval from the cloth placing roller 3 to the unfolding roller 5 is reduced. At this time, the connecting block 41 located on the side close to the heat sealing machine 2 moves upward, and drives the rotating roller 42 to move upward. The tension on the non-woven fabric in the interval between the heat sealing machine 2 and the rotating roller 42 increases, and the non-woven fabric located on the unfolding roller 5 is pulled to unfold the wrinkles of the non-woven fabric parallel to the moving direction. At the same time, a heating wire is arranged inside the unfolding roller 5 to iron the wrinkles. The longitudinal unfolding block 51 is close to the unfolding roller 5 and abuts against the surface of the non-woven fabric away from the unfolding roller 5. At this time, the clockwork spring drives the tensioning wheel 52 to rotate, so that the tensioning wheel 52 unfolds the wrinkles perpendicular to the moving direction of the fabric and eliminates the wrinkles when the unfolding roller 5 irons the non-woven fabric.

[0049] The heat sealing machine 2 heat-seals the non-woven fabric, and in the process, the rotating motor 9 drives the two ends of the jack mechanism 63 to approach each other, and the two connecting plates 61 are recycled. During the recycling process, the clamping strips 8 set on the two connecting plates 61 are relatively close to and abut against each other, and then rotate after abutting to loosen the fixation of the shaping plate 62.

[0050] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
