Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric processing and positioning technology, specifically a nonwoven fabric positioning structure for multi-station bonding. Background Technology

[0002] In the processing and bonding of nonwoven fabrics, precise material positioning is one of the key aspects to ensure product quality.

[0003] Currently, some positioning devices based on technologies such as mechanical clamping, pneumatic adsorption, or photoelectric detection have appeared on the market. However, these devices often suffer from insufficient efficiency when operating in multiple workstations. In addition, in practical applications, these devices often require frequent structural adjustments to accommodate different specifications of nonwoven fabrics, increasing operational complexity and time costs.

[0004] Furthermore, many existing devices require additional time to complete position adjustments and recalibration when switching between multiple workstations, which limits production efficiency.

[0005] Therefore, we have made improvements to this and proposed a nonwoven fabric positioning structure for multi-station bonding. Utility Model Content

[0006] The purpose of this invention is to solve the problems of insufficient efficiency, increased operational complexity, and high time cost caused by frequent structural adjustments in the existing non-woven fabric positioning structure during multi-station operation.

[0007] To achieve the aforementioned objectives and address the problems, this utility model provides a multi-station bonding nonwoven fabric positioning structure, comprising a positioning support frame, an adjustment component, and a positioning clamping component. The top of the positioning support frame is provided with a sliding rail, on which multiple adjustment components are mounted. These adjustment components are slidably connected to the sliding rail to enable rapid switching between multiple stations. The positioning clamping component is fixed to the bottom of the adjustment components and achieves precise positioning of the nonwoven fabric through the movement of the adjustment components.

[0008] The adjustment assembly includes a slider, a drive gear, and a locking mechanism. The slider has a mounting groove at its bottom, and the drive gear is movably connected to one side of the slider via a bearing and meshes with the teeth on the sliding track. The locking mechanism includes a locking screw and a locking washer. The locking screw passes through the slider and contacts the side of the sliding track. Rotating the locking screw causes the locking washer to press against the sliding track, thereby fixing the slider at a designated position on the sliding track.

[0009] The positioning and clamping assembly includes a clamping plate, an elastic pressure strip, and an adsorption module. The clamping plate has mounting holes at both ends, which are fixedly connected to the mounting groove of the adjusting assembly via bolts. The elastic pressure strip is fixed to the inner side of the clamping plate and has multiple protrusions on its surface to enhance friction with the non-woven fabric. The adsorption module is embedded in the middle of the clamping plate, and its surface has multiple adsorption holes connected to an external vacuum pump via an internal air passage for adsorbing the non-woven fabric.

[0010] As a preferred technical solution of this application, the sliding track is provided with guide grooves on both sides, and the slider is provided with guide blocks on both sides that cooperate with the guide grooves. The guide blocks are embedded in the guide grooves, and the guide grooves restrict the movement direction of the slider, ensuring the smooth operation of the slider on the sliding track.

[0011] As a preferred technical solution of this application, one end of the drive gear is provided with a knob, and the outer surface of the knob is provided with anti-slip texture. By rotating the knob, the drive gear is driven to rotate, thereby pushing the slider to move along the sliding track, realizing the position adjustment of the adjustment component.

[0012] As a preferred embodiment of this application, the locking mechanism further includes a spring washer, which is sleeved on the locking screw and located between the locking washer and the slider. When the locking screw is tightened, the spring washer is compressed and deformed, providing additional locking force and preventing the locking mechanism from loosening due to vibration.

[0013] As a preferred technical solution of this application, the clamping plate has a groove on its inner side, and the elastic strip is fixed to the clamping plate by embedding it into the groove. The depth of the groove is slightly less than the thickness of the elastic strip, so that the elastic strip can slightly protrude from the inner surface of the clamping plate after installation, thereby enhancing the clamping effect on the nonwoven fabric.

[0014] As a preferred technical solution of this application, the adsorption pores of the adsorption module are arranged in an array, with a partition between each row of adsorption pores. The height of the partition is slightly lower than the surface height of the adsorption module. The partition is used to separate the adsorption pores in different areas, avoiding uneven distribution of adsorption force that could cause local deformation of the nonwoven fabric.

[0015] As a preferred technical solution of this application, the bottom of the positioning support frame is provided with a support foot, and the bottom of the support foot is provided with an anti-slip rubber pad. The anti-slip rubber pad is fixed to the bottom of the support foot with screws to increase the stability of the positioning support frame and prevent slippage during operation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By incorporating adjustment components and sliding tracks, the positioning and clamping assembly achieves rapid switching between multiple workstations. The drive gear and locking mechanism in the adjustment component work together to make position adjustments more precise and easier to operate. The combination of elastic pressure strips and adsorption modules in the positioning and clamping assembly not only enhances the clamping force on the non-woven fabric but also further improves positioning stability through adsorption. The design of guide grooves and guide blocks ensures smooth operation of the slider on the sliding track, avoiding positioning deviations caused by poor sliding. The introduction of spring washers effectively prevents the locking mechanism from loosening due to vibration, further improving the reliability of the equipment. The overall structure is compact and easy to operate, significantly improving the efficiency of multi-station operations, reducing the time cost required for frequent structural adjustments, and solving the problem of insufficient efficiency in multi-station operations in existing technologies.

[0028] This utility model relates to a nonwoven fabric positioning structure for multi-station bonding, the overall structure of which is as follows: Figure 1As shown, the device includes a positioning support frame 1, a sliding rail 2, an adjustment assembly 3, and a positioning clamping assembly 4. The positioning support frame 1 serves as the foundation of the entire device, with the sliding rail 2 mounted on its top. The sliding rail 2 extends along the length of the positioning support frame 1, providing a movement path for the adjustment assembly 3. The adjustment assembly 3 is installed in conjunction with the sliding rail 2 via a slider 5. The slider 5 has a mounting groove at its bottom for fixing the positioning clamping assembly 4. The positioning clamping assembly 4 consists of a clamping plate 8, an elastic pressure strip 9, and an adsorption module 10. The clamping plate 8 is connected to the mounting groove of the slider 5 by bolts. The elastic pressure strip 9 is embedded in a groove on the inner side of the clamping plate 8. The adsorption module 10 is embedded in the middle of the clamping plate 8 and connected to an external vacuum pump via an internal air passage.

[0029] The specific structure of sliding track 2 is as follows Figure 3 As shown, guide grooves 11 are provided on both sides of the slider 5, and guide blocks 12 are provided on both sides of the slider 5. The guide blocks 12 are embedded in the guide grooves 11 to form a sliding fit. The depth of the guide grooves 11 is slightly greater than the height of the guide blocks 12 to ensure that the slider 5 can move smoothly on the sliding track 2 without falling off the track. The tooth surface of the sliding track 2 is located on one side, and the drive gear 6 is movably connected to one side of the slider 5 through a bearing and meshes with the tooth surface. A knob 13 is provided at one end of the drive gear 6. The outer surface of the knob 13 has anti-slip texture. By manually rotating the knob 13, the drive gear 6 is rotated, thereby pushing the slider 5 to move along the sliding track 2. The locking mechanism 7 includes a locking screw 14, a locking washer 15, and a spring washer 16. The locking screw 14 passes through the slider 5 and contacts the side of the sliding track 2. When the locking screw 14 is tightened, the locking washer 15 presses against the side of the sliding track 2, and at the same time, the spring washer 16 is deformed by pressure, providing additional locking force to prevent the slider 5 from loosening due to vibration.

[0030] The specific structure of the positioning and clamping component 4 is as follows: Figure 2 As shown, the clamping plate 8 has mounting holes at both ends, which are fixedly connected to the mounting groove at the bottom of the slider 5 by bolts. The clamping plate 8 has a groove on its inner side, and the elastic pressure strip 9 is fixed to the clamping plate 8 by embedding it into the groove. The depth of the groove is slightly less than the thickness of the elastic pressure strip 9, allowing the elastic pressure strip 9 to slightly protrude from the inner surface of the clamping plate 8 after installation. The surface of the elastic pressure strip 9 has multiple protrusions, which are evenly distributed to enhance the friction between the elastic pressure strip 9 and the nonwoven fabric. The adsorption module 10 is embedded in the middle of the clamping plate 8. The surface of the adsorption module 10 has multiple adsorption holes 17 arranged in an array. A partition 18 is provided between each row of adsorption holes 17, and the height of the partition 18 is slightly lower than the surface height of the adsorption module 10. The partition 18 separates the adsorption holes 17 in different areas, preventing uneven distribution of adsorption force from causing localized deformation of the nonwoven fabric. The adsorption hole 17 is connected to an external vacuum pump through an internal air passage. When the vacuum pump is started, the adsorption hole 17 generates negative pressure, which adsorbs the non-woven fabric onto the surface of the adsorption module 10.

[0031] The specific structure of adjustment component 3 is as follows: Figure 2 as well as Figure 4 As shown, slider 5, as the core component of adjustment assembly 3, has a mounting groove at its bottom for fixing clamping plate 8. Drive gear 6 is movably connected to one side of slider 5 via bearings and meshes with the tooth surface of sliding track 2. Rotating knob 13 drives drive gear 6 to rotate, thereby moving slider 5 along sliding track 2. Locking screw 14 in locking mechanism 7 passes through slider 5 and contacts the side of sliding track 2. Locking washer 15 is located between locking screw 14 and sliding track 2. When locking screw 14 is tightened, locking washer 15 presses against the side of sliding track 2, while spring washer 16 deforms under pressure, providing additional locking force to prevent slider 5 from loosening due to vibration. Guide block 12 is embedded in guide groove 11, which restricts the movement direction of slider 5, ensuring smooth operation of slider 5 on sliding track 2.

[0032] The bottom of the positioning support frame 1 is provided with support feet 19, and the bottom of the support feet 19 is provided with anti-slip rubber pads 20. The anti-slip rubber pads 20 are fixed to the bottom of the support feet 19 by screws to increase the stability of the positioning support frame 1 and prevent slippage during operation. There are four support feet 19, located at the four corners of the positioning support frame 1 to ensure the balance of the entire device.

[0033] The working process of this utility model is as follows: First, the non-woven fabric is placed on the surface of the adsorption module 10. The external vacuum pump is started, and the adsorption hole 17 generates negative pressure, adsorbing the non-woven fabric onto the surface of the adsorption module 10. At this time, the protrusion of the elastic pressure strip 9 contacts the non-woven fabric, and the clamping effect on the non-woven fabric is further enhanced by friction. Then, according to actual needs, the knob 13 is manually rotated to drive the drive gear 6 to rotate, pushing the slider 5 to move along the sliding track 2 to the target position. When the slider 5 reaches the designated position, the locking screw 14 is tightened, so that the locking washer 15 presses against the side of the sliding track 2. At the same time, the spring washer 16 is deformed by pressure, providing additional locking force to ensure that the slider 5 is fixed in the designated position on the sliding track 2. After completing the operation of one station, the above steps can be repeated to move the slider 5 to the next station for operation. Throughout the process, the cooperation between the guide block 12 and the guide groove 11 ensures the smooth operation of the slider 5 on the sliding track 2, avoiding positioning deviation caused by poor sliding.

[0034] The design of the positioning support frame 1 gives the entire device high stability. The anti-slip rubber pads 20 on the bottom of the support feet 19 further enhance the anti-slip performance of the device, ensuring that it will not move due to external interference during operation. The partitions 18 in the adsorption module 10 effectively avoid the problem of uneven distribution of adsorption force, ensuring that the non-woven fabric will not undergo local deformation during adsorption. The protrusions of the elastic pressure strip 9, combined with the adsorption function of the adsorption module 10, not only enhance the clamping force on the non-woven fabric, but also improve the stability of positioning.

[0035] This invention, through the cooperation of the sliding rail 2 and the adjusting component 3, enables the positioning and clamping component 4 to quickly switch between multiple workstations, significantly improving the efficiency of multi-station operation. The locking mechanism 7 effectively prevents the slider 5 from loosening due to vibration, further enhancing the reliability of the equipment. The overall structure is compact and easy to operate, significantly reducing the time cost required for frequent structural adjustments and solving the problem of insufficient efficiency in multi-station operation in existing technologies.

[0036] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0037] In actual production, the multi-station bonding operation of nonwoven fabrics requires frequent adjustments to its position to adapt to different processing needs. First, the nonwoven fabric to be processed is placed on the surface of the adsorption module 10. After starting the external vacuum pump, the adsorption holes 17 firmly adsorb the nonwoven fabric onto the surface of the adsorption module 10 through negative pressure. Since the adsorption holes 17 are arranged in an array, and partitions 18 are provided between each row of adsorption holes 17, with the height of the partitions 18 slightly lower than the surface height of the adsorption module 10, the adsorption forces in different areas can be effectively separated, preventing deformation of the nonwoven fabric due to uneven adsorption forces. Simultaneously, the protrusions of the elastic pressure strip 9 contact the surface of the nonwoven fabric, and the evenly distributed protrusions on its surface enhance the friction between the strip and the nonwoven fabric, thereby further improving the clamping stability.

[0038] Next, according to the process requirements, the non-woven fabric needs to be moved to the first station for bonding. At this time, the knob 13 is manually rotated. The anti-slip texture on the outer surface of the knob 13 increases the friction during operation, making it easier to control precisely. The knob 13 drives the drive gear 6 to rotate, and the drive gear 6 meshes with the tooth surface on the sliding rail 2, thereby pushing the slider 5 to move smoothly along the sliding rail 2. The guide blocks 12 on both sides of the slider 5 are embedded in the guide grooves 11 on both sides of the sliding rail 2. The depth of the guide grooves 11 is slightly greater than the height of the guide blocks 12, ensuring that the slider 5 will not fall off the rail during the sliding process, while limiting the direction of movement of the slider 5 and ensuring the straightness of its running trajectory. After the slider 5 is moved to the target position, the locking screw 14 is tightened. The locking washer 15 presses against the side of the sliding rail 2, and the spring washer 16 is deformed under pressure, providing additional locking force to prevent the slider 5 from loosening due to vibration, thereby ensuring that the positioning clamping assembly 4 remains stable in the designated position.

[0039] After completing the operation at the first station, unlock the locking mechanism 7 by loosening the locking screw 14 and rotating the knob 13 again to move the slider 5 along the sliding track 2 to the next station. Repeat the above steps until all stations are completed. Throughout the process, the anti-slip rubber pads 20 at the bottom of the support feet 19 are fixed to the support feet 19 with screws, providing good stability for the entire device and preventing the device from sliding or tilting due to external interference. In addition, the design of the positioning support frame 1 gives the overall structure a high load-bearing capacity, ensuring that the device remains balanced during multi-station switching.

[0040] As can be seen from the above steps, the drive gear 6 and locking mechanism 7 in the adjusting component 3 work together to achieve rapid and precise positioning of the slider 5 on the sliding track 2. The adsorption function of the adsorption module 10, combined with the friction-enhancing effect of the elastic pressure strip 9, not only solves the problem of insufficient clamping force in traditional positioning methods, but also significantly improves the stability of positioning. At the same time, the cooperative design of the guide groove 11 and the guide block 12 ensures the smoothness of the slider 5 during the sliding process, avoiding positioning deviations caused by poor sliding. The introduction of the spring washer 16 further enhances the reliability of the locking mechanism 7, preventing loosening caused by vibration.

[0041] In summary, by optimizing the structural design of the sliding track 2, the adjusting component 3, and the positioning clamping component 4, this utility model significantly improves the efficiency of multi-station operation, reduces the time cost required for frequent structural adjustments, solves the problem of insufficient efficiency in multi-station operation in the prior art, and provides reliable technical support for the efficient processing of nonwoven fabrics.
