Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a web-laying device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric is a type of fabric formed without spinning or weaving. It is made by arranging short or long textile fibers in a directional or random manner to form a web structure, and then reinforcing it using mechanical, thermal, or chemical methods. It is not made by interlacing or weaving individual yarns together, but by directly bonding the fibers together through physical methods. This breaks through the traditional textile principles and has the characteristics of short process flow, fast production speed, high output, low cost, wide range of uses, and multiple raw material sources.

[0003] In existing technologies using electric conveyor belts, loose fibers from a transported fiber web can easily adhere to the belt. These fibers may get caught in the shaft of the conveyor rollers, affecting operation, or stack on the next fiber web, causing uneven thickness. Manual cleaning of the conveyor belt is cumbersome and inconvenient. Furthermore, there is a lack of protection during the transport and laying of the fiber web. When the fiber web falls from the bottom of the conveyor, it is easily affected by the displacement of the conveyor and is subject to a swinging effect. This swinging effect is greater than that on the sides of the material to be laid on the electric conveyor belt, which can easily lead to the fiber web being laid outside the sides of the material and having significant misalignment at the edges. This affects the uniformity and edge flatness of subsequent laying.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a web-laying device for nonwoven fabric production to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a nonwoven fabric production web laying device, including a horizontally arranged conveyor belt and a laying assembly mounted on the top of the conveyor belt. Vertical support plates are connected to both ends of the conveyor rollers within the conveyor belt along their own axial direction. Limiting mechanisms are provided at both ends of the laying assembly. A cleaning mechanism is provided at the bottom of the conveyor belt, with a driving mechanism connected to one end of the cleaning mechanism. The cleaning mechanism includes:

[0007] A drive wheel is connected to one side of the transmission roller along its own axial direction. A driven wheel is engaged at its bottom. A fixed frame is coaxially fixed to the side wall of the driven wheel near the transmission belt. A horizontal cleaning roller is detachably connected to the end of the fixed frame away from the axis of the driven wheel. The drive mechanism includes:

[0008] Gear 2 is fixed to the side of the transmission roller near the drive wheel. Gear 3 meshes with one side of it in the horizontal direction. Gear 3 is coaxial with the drive wheel and the cross-sectional radius of gear 3 is larger than that of gear 2. A fixed shaft is coaxially fixed to the side of gear 3 near the drive wheel. A limiting rod extending radially along the fixed shaft is fixed on the outer arc wall of the fixed shaft.

[0009] A coil spring is fixedly sleeved on the outside of a fixed shaft. A rotating plate is rotatably sleeved on the outside of the fixed shaft. The outer end of the coil spring is fixed to the outer edge of the side wall of the rotating plate. A notch is opened on the outer arc wall of the rotating plate. A limit block is engaged in the notch. A reset spring is fixed on the side wall of the limit block away from the axis of the rotating plate. A sleeve shaft is fixed on the side wall of the rotating plate away from the gear three. The sleeve shaft is fixedly connected to the drive wheel.

[0010] Furthermore, the outer arc wall of the fixed frame is fixed with a plurality of extensions arranged in a ring array about the fixed frame. The end of each extension away from the fixed frame is detachably connected to a horizontal cleaning roller. The outer arc wall of the driven wheel is provided with a plurality of limiting grooves arranged in a ring array about its axial direction and extending radially therein. The plurality of limiting grooves correspond one-to-one with the plurality of cleaning rollers.

[0011] Furthermore, a fixed frame is rotatably sleeved on the outer side of the rotating plate. A protruding groove is provided on the outer arc wall of the fixed frame corresponding to the position of the limiting block. The limiting block and the reset spring are both set in the groove. The axial direction of the reset spring is consistent with the radial direction of the rotating plate. The end of the limiting rod away from the fixed axis is set on both sides of the circumference of the rotating plate, and the end of the limiting rod away from the fixed axis slides against the limiting block. A magnetic coupler is provided on the side wall of the cleaning roller away from the driven wheel. A motor is provided on the support plate away from the drive mechanism at the position of the cleaning roller at the top. A matching magnetic coupler is installed at the output end of the motor.

[0012] Furthermore, the laying assembly has a placement channel at both ends along the axial direction of the transmission roller. The limiting mechanism includes a second motor fixed to the laying assembly. A transmission wheel set is fixed at the output end of the second motor. The axial direction of the transmission wheel set is consistent with the conveying direction of the transmission belt. A gear is coaxially fixed at the end of the transmission wheel set away from the second motor and close to the center of the laying assembly. A gear with the same structure meshes with the gear on the side away from the second motor. A horizontal rack is meshed on the side of the two gears that are close to each other. The rack slides horizontally on the inner wall of the placement channel. A vertical limiting plate is fixed at the side of the rack close to the center of the laying assembly. The side of the limiting plate close to the center of the transmission belt is arc-shaped. A scale is coaxially fixed at the end of the transmission wheel set away from the second motor and away from the center of the laying assembly. The scale is provided on the side wall of the scale.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cleaning mechanism is driven by the drive mechanism, so that the cleaning rollers are automatically switched after the conveyor belt runs for a certain period of time. Multiple cleaning rollers distributed in a ring array on the fixed frame contact the surface of the conveyor belt in turn for cleaning. Each cleaning roller works in turn, resulting in more uniform wear distribution. This avoids excessive wear in some areas caused by cleaning a single roller in a fixed position for a long time. It also reduces the frequency of maintenance and cleaning, reduces the burden on the staff, and has a simple structure that is easy to maintain and has stronger anti-interference ability.

[0015] 2. The limiting mechanism moves the limiting plates on both sides to the edge of the material. When the laying component moves back and forth to lay the fiber single network, it can block the falling fiber single network on both sides of the material, preventing the fiber single network from being flung and laid outside the material when the laying component moves. This makes the non-woven fabric laid more neatly on both sides, which is convenient for subsequent processing. The dial makes it easy for the operator to intuitively understand the current spacing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a nonwoven fabric production web laying device, comprising a horizontally arranged conveyor belt 10 and a laying assembly 11 mounted on the top of the conveyor belt 10. Vertical support plates are connected to both ends of the conveyor rollers within the conveyor belt 10 along their axial direction. Limiting mechanisms are provided at both ends of the laying assembly 11. A cleaning mechanism is provided at the bottom of the conveyor belt 10, with a driving mechanism connected to one end of the cleaning mechanism. The cleaning mechanism includes:

[0028] A drive wheel 20 is connected to one side of the transmission roller along its own axial direction, and a driven wheel 21 is engaged at its bottom. A fixing frame 22 is coaxially fixed to the side wall of the driven wheel 21 near the transmission belt 10. A horizontal cleaning roller 23 is detachably connected to the end of the fixing frame 22 away from the axis of the driven wheel 21. The drive mechanism includes:

[0029] Gear 2 30 is fixed to the side of the transmission roller near the drive wheel 20. Gear 3 31 meshes with one side of it in the horizontal direction. Gear 3 31 is coaxial with the drive wheel 20 and the cross-sectional radius of gear 3 31 is larger than that of gear 2 30. A fixed shaft 32 is fixed coaxially to the side of gear 3 31 near the drive wheel 20. A limiting rod 321 extending radially along the fixed shaft 32 is fixed on the outer arc wall of the fixed shaft 32.

[0030] A coil spring 33 is fixedly sleeved on the outside of a fixed shaft 32. A rotating plate 331 is rotatably sleeved on the outside of the fixed shaft 32. The outer end of the coil spring 33 is fixed to the outer edge of the side wall of the rotating plate 331. A notch is opened on the outer arc wall of the rotating plate 331. A limiting block 34 is engaged in the notch. A reset spring 341 is fixed on the side wall of the limiting block 34 away from the axis of the rotating plate 331. A sleeve shaft 201 is fixed on the side wall of the rotating plate 331 away from the gear 31. The sleeve shaft 201 is fixedly connected to the drive wheel 20.

[0031] The outer arc wall of the fixed frame 22 is fixed with a plurality of extensions arranged in a ring array about the fixed frame 22. The end of the extensions away from the fixed frame 22 can be detachably connected to a horizontal cleaning roller 23. The outer arc wall of the driven wheel 21 is provided with a plurality of limiting grooves arranged in a ring array about its axial direction and extending along its radial direction. The plurality of limiting grooves correspond one-to-one with the plurality of cleaning rollers 23.

[0032] A fixed frame 35 is rotatably sleeved on the outer side of the rotating plate 331. A protruding groove is provided on the outer arc wall of the fixed frame 35 at the position corresponding to the position of the limiting block 34. The limiting block 34 and the reset spring 341 are both set in the groove. The axial direction of the reset spring 341 is consistent with the radial direction of the rotating plate 331. The end of the limiting rod 321 away from the fixed shaft 32 is set on both sides of the circumference of the rotating plate 331 with an inclined surface, and the end of the limiting rod 321 away from the fixed shaft 32 slides against the limiting block 34.

[0033] A magnetic coupler is provided on the side wall of the cleaning roller 23 away from the driven wheel 21. A motor is provided on the support plate away from the drive mechanism at the position corresponding to the top of the cleaning roller 23. A matching magnetic coupler is installed at the output end of the motor.

[0034] It should be noted that: Gear 2 30 is fixed on the side of the transmission roller near the drive wheel 20 and rotates synchronously with the transmission roller. Gear 2 30 meshes with gear 31 to amplify the torque, driving the fixed shaft 32 to rotate. In the initial state, the limiting block 34 is engaged in the recess of the outer arc wall of the rotating plate 331. The rotation of the fixed shaft 32 drives the coil spring 33 to contract and store energy. At the same time, the limiting rod 321 also rotates with the fixed shaft 32. The rotating plate 331 is sleeved on the outside of the fixed shaft 32. Due to the engagement of the limiting block 34 at this time, the normal energy storage of the coil spring 33 is ensured and the shaking of the rotating plate 331 is prevented.

[0035] When gear 31 rotates once, fixed shaft 32 and its limiting rod 321 also rotate once. At this time, the inclined surface at the end of limiting rod 321 slides against limiting block 34, forcing limiting block 34 to move away from rotating plate 331 and compressing reset spring 341. As limiting block 34 leaves the notch, rotating plate 331 loses its restriction and releases stored energy under the action of coil spring 33. Through sleeve shaft 201, it drives drive wheel 20 to rotate. When drive wheel 20 rotates once, it can mesh with driven wheel 21 to rotate at a fixed angle, thereby causing the next cleaning roller 23 to move to contact the conveyor belt 10 for cleaning.

[0036] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: the laying component assembly 11 has a placement channel at both ends along the axial direction of the transmission roller, and the limiting mechanism includes a second motor 12 fixed on the laying component assembly 11. A transmission wheel set 13 is fixed at the output end of the second motor 12. The axial direction of the transmission wheel set 13 is consistent with the conveying direction of the transmission belt 10. A gear 14 is coaxially fixed at one end of the transmission wheel set 13 away from the second motor 12 and close to the center of the laying component assembly 11.

[0037] The gear 14 is meshed with a gear 14 with the same structure on the side away from the motor 12. The two gears 14 are meshed with a horizontal rack 15 on the side that is close to each other. The rack 15 slides horizontally on the inner wall of the storage channel. A vertical limiting plate 16 is fixed on the side of the rack 15 near the center of the laying component assembly 11. The side of the limiting plate 16 near the center of the conveyor belt 10 is set with an arc surface.

[0038] The transmission wheel assembly 13 is coaxially fixed at one end away from the center of the laying component assembly 11 on the side away from the motor 2 12, and the scale is provided on the side wall of the scale 17.

[0039] It should be noted that the laying component assembly 11 here is prior art and will not be described in detail here. It can be understood that the limiting mechanism is set at the corresponding positions on the outer and inner sides of the housing of the laying component assembly 11. The second motor 12 is fixed on the laying component assembly 11 and the output end is connected to the transmission wheel set 13. In one possible embodiment, the transmission wheel set 13 consists of two pulleys with the same structure. The same belt is sleeved in the groove of the two pulleys. The pulley located away from the second motor 12 is fixed with a gear 14 on the side wall of the laying component assembly 11.

[0040] Both gears 14 mesh with rack 15, synchronously pushing the limit plate 16 on the same side to move synchronously. To further ensure stability, gears 14 and rack 15 with the same structure can be set on the side of the limit plate 16 away from motor 12. The gears 14 located on both sides and at the same horizontal height are fixed with the same connecting shaft on the side that is close to each other for power transmission. Then the limit mechanisms on both sides of the laying component assembly 11 in the length direction can be synchronized through the transmission mechanism to ensure that the distance and timing of the extension of the limit plates 16 on both sides are synchronized.

[0041] The side of the limiting plate 16 closest to the center of the conveyor belt 10 is curved, forming a gradual guide when it comes into contact with the fiber single web, rather than a sharp edge cut, reducing fiber breakage or fuzzing, improving the surface quality of the nonwoven fabric, adapting to fiber single webs of different thicknesses, and avoiding jamming or displacement. The side wall of the scale 17 is provided with graduations, making it easy to intuitively understand the current extension distance of the limiting plate 16.

[0042] Working principle:

[0043] In the cleaning mechanism, the transmission roller drives the second gear 30 to rotate, and the meshing gear 31 amplifies the torque, driving the fixed shaft 32 to rotate. Initially, the limit block 34 is engaged in the recess of the rotating plate 331, and the coil spring 33 stores energy. After the fixed shaft 32 rotates one revolution, the inclined surface of the limit rod 321 presses the limit block 34, causing it to disengage from the recess. Under the action of the coil spring 33, the rotating plate 331 drives the drive wheel 20 to rotate through the sleeve shaft 201. The drive wheel 20 meshes with the driven wheel 21, causing the cleaning roller 23 on the fixed frame 22 to successively contact the transmission belt 10 for cleaning.

[0044] In the limiting mechanism, motor 2 12 drives transmission wheel set 13, which drives gear 1 14 on both sides to rotate synchronously. The meshing rack rod 15 pushes the limiting plate 16 to move horizontally. The arc-shaped limiting plate 16 can reduce fiber damage. The scale 17 makes it easy to intuitively adjust the extension distance of the limiting plate 16, ensuring accurate fiber web laying.
