Description

Technical Field

[0001] This utility model belongs to the technical field of garment processing equipment, specifically relating to a standardized automatic processing and sewing device for hat brims. Background Technology

[0002] Traditional hat brim sewing mainly relies on manual operation, which has three major technical bottlenecks:

[0003] Difficulty in controlling curvature: Poor consistency in curvature when manually bending the brim causes the stitches to deviate from the design curve, resulting in a product qualification rate of less than 85%; Fabric positioning deviation: Multiple layers of fabric (outer fabric, lining, and shaping sheet) are prone to slipping when stacked, resulting in a misalignment of 1-3mm at the edges after sewing; Low level of automation: Existing semi-automatic equipment can only complete straight-line sewing, and curved sewing requires frequent manual adjustments, taking more than 5 minutes per piece.

[0004] Existing technologies attempt to fix the fabric using a vacuum adsorption table, but thin materials are easily deformed by the adsorption. Using mechanical templates for limiting the size results in low changeover efficiency, requiring a shutdown of more than 15 minutes each time the size is changed. In addition, sewing machine heads mostly move along fixed tracks, making it difficult to adapt to the curvature changes of different sized brims, resulting in a trade-off between production efficiency and precision.

[0005] To address the aforementioned shortcomings, this invention aims to provide an automated device that integrates adaptive fabric clamping, high-precision curved sewing, and rapid shape change, thereby solving the problems of curvature distortion, positioning drift, and low efficiency in hat brim processing. Utility Model Content

[0006] The purpose of this invention is to provide a standardized automatic processing and sewing device for hat brims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a standardized automatic processing and sewing device for hat brims, comprising a base plate, with inverted U-shaped first connecting frames fixedly connected to both ends of the base plate, rollers axially connected to the lower ends of the opposite sides of the first connecting frames, and a sliding groove provided on the upper end of each first connecting frame, with limiting grooves provided in the middle of both sides of the sliding grooves, and limiting plates slidably connected to the sliding grooves, and a driving component fixedly connected to the upper end of each first connecting frame, with a fabric body provided between the rollers and the limiting plates, and a second connecting frame fixedly connected to the middle of both sides of the base plate, with symmetrical sliding frames of adjusting components fixedly connected to the upper ends of the opposite sides of the second connecting frames, at least two sets of movable frames slidably connected to the outer surface of the sliding frames, with processing components fixedly connected to the lower ends of the movable frames, and a base fixedly connected to the middle of the upper end of the base plate.

[0008] It should be noted in the solution that the lower end of the limiting plate is provided with an arc-shaped groove, the outer surface of the groove is fixedly connected with an anti-slip pad, and both ends of the limiting plate are fixedly connected with connecting blocks. Both sides of the connecting blocks are fixedly connected with protruding guides. The connecting blocks are slidably connected to the sliding groove, and both sides of the protruding guides are slidably connected to the limiting groove. Both ends of the connecting blocks are fixedly connected with fixing blocks.

[0009] It is further worth noting that each of the drive components includes a first servo motor fixedly connected by an inverted U-shaped bracket. The first output shaft of the first servo motor is engaged with the middle of the driven shaft via a synchronous belt. The outer surfaces of both ends of the driven shaft are fixedly connected to one end of a connecting belt. The lower ends of the connecting belt are fixedly connected to the upper end of a fixing block. Limiting rings are fixedly connected to both sides of the outer surface of the synchronous belt, the outer surface of the driven shaft, and the outer surface of the connecting belt.

[0010] It should be further noted that the middle of each connecting belt is limited by a caster wheel fixedly connected to one side of the first connecting frame.

[0011] In a preferred embodiment, the upper middle part of each of the symmetrical sliding frames is provided with a groove, and each groove is provided with a plurality of pulleys, and a locking tooth is provided on one side of the rear sliding frame.

[0012] In a preferred embodiment, the control component further includes a second servo motor, the other end of which is slidably connected to the upper end of the movable frame and engages with the locking teeth of the rear sliding frame.

[0013] In a preferred embodiment, a pad is fixedly connected to the upper end of the base, and the upper end of the pad is provided with at least two sets of positioning grooves, and an infrared positioning device is provided on the outside of each positioning groove.

[0014] Compared with the prior art, the standardized automatic processing and sewing device for hat brims provided by this utility model has at least the following beneficial effects:

[0015] (1) This device achieves precise bidirectional traction of the fabric by coordinating the roller shaft and the limiting plate integrated by the inverted U-shaped connecting frame, combined with the closed-loop transmission system consisting of the servo motor in the drive assembly via the synchronous belt and connecting belt. The arc-shaped groove at the bottom of the limiting plate and the anti-slip pad form an adaptive clamping surface, ensuring that the brim fabric does not shift during high-speed movement; at the same time, the control assembly drives the movable frame to adjust along the sliding frame in multiple positions, and the infrared positioning device on the base calibrates the processing position in real time, so that the error between the sewing trajectory and the preset standardized brim contour is ≤0.3mm. Compared with the traditional manual positioning method, the sewing efficiency is increased by more than 2 times, and the product qualification rate reaches 98.5%.

[0016] (2) The innovative design of the sliding groove and limiting groove dual-rail guide structure allows the limiting plate to achieve zero-gap vertical lifting through the raised guide, which can quickly adapt to different thicknesses of brim materials. The flexible limiting of the universal wheel pair connecting belt in the drive component effectively eliminates transmission vibration; the control component uses the meshing transmission of pulley group and cleat to enable the processing component to move steplessly on the sliding frame, and complete the switching of sewing paths for multiple specifications of brim with one click. With the modular positioning groove of the pad block, the changeover time is shortened from the original 15 minutes to 40 seconds, significantly reducing the complexity of operation and the intensity of manual intervention.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides a standardized automatic processing and sewing device for hat brims, comprising: a base plate 1, with inverted U-shaped first connecting frames 2 fixedly connected to both ends of the base plate 1, roller shafts 3 axially connected to the lower ends of the opposite sides of the first connecting frames 2, and a sliding groove 201 provided on the upper end of the first connecting frames 2, with limiting grooves 202 provided in the middle of both sides of the sliding grooves 201, and limiting plates 5 slidably connected to the sliding grooves 201, and a driving component 6 fixedly connected to the upper end of the first connecting frames 2, with a fabric body 4 provided between the roller shafts 3 and the limiting plates 5, and a second connecting frame 8 fixedly connected to the middle of both sides of the base plate 1, with symmetrical sliding frames 901 fixedly connected to the upper ends of the opposite sides of the second connecting frames 8, and at least two sets of movable frames 906 slidably connected to the outer surface of the sliding frames 901, with a processing component 10 fixedly connected to the lower end of each movable frame 906, and a base 7 fixedly connected to the middle of the upper end of the base plate 1.

[0025] Further as Figure 5 As shown, it is worth noting that each of the limiting plates 5 has an arc-shaped groove 501 at its lower end. An anti-slip pad 502 is fixedly connected to the outer surface of the groove 501. Connecting blocks 503 are fixedly connected to both ends of the limiting plate 5. Protruding guides 504 are fixedly connected to both sides of the connecting blocks 503. The connecting blocks 503 are slidably connected to the sliding groove 201, and the protruding guides 504 are slidably connected to the limiting groove 202. Fixing blocks 505 are fixedly connected to both ends of the connecting blocks 503. The arc-shaped groove 501 of the limiting plate 5, together with the anti-slip pad 502, forms a flexible clamping surface, so that the fabric 4 is subjected to uniform force when pressed, avoiding deformation of thin materials. The double limiting structure of the connecting blocks 503 and the protruding guides 504 ensures that the limiting plate 5 moves vertically up and down along the sliding groove 201 without deviation. The lifting and positioning accuracy reaches ±0.1mm, which significantly improves the edge alignment consistency of the brim sewing.

[0026] Further as Figure 1 As shown, it is worth noting that each drive assembly 6 includes a first servo motor 605 fixedly connected by an inverted U-shaped mounting bracket 606. The first output shafts 607 of the first servo motor 605 are all engaged with the middle of the driven shaft 603 via a synchronous belt 608. The outer surfaces of both ends of the driven shaft 603 are fixedly connected to one end of a connecting belt 601, and the lower ends of the connecting belt 601 are respectively fixedly connected to the upper end of the fixing block 505. The first output shafts 607 are located on both sides of the outer surface of the synchronous belt 608, and the driven shafts 603 are located on... Limiting rings 604 are fixedly connected to both sides of the outer surface of the synchronous belt 608 and the driven shaft 603 on both sides of the outer surface of the connecting belt 601. The driven shaft 603 is driven by the first servo motor 605 through the synchronous belt 608, and then the limiting plate 5 is pulled by the connecting belt 601 to form a closed-loop power transmission. The limiting rings 604 constrain axial displacement at the transmission node between the synchronous belt 608 and the connecting belt 601, eliminating the risk of belt slippage during high-speed operation, and improving the transmission efficiency to over 95%. The conveying speed of the fabric 4 can reach 1.5m / s.

[0027] Further as Figure 1 As shown, it is worth noting that the middle of the connecting belt 601 is limited by the universal wheel 602 fixedly connected to one side of the first connecting frame 2. The universal wheel 602 flexibly guides the middle of the connecting belt 601, offsetting the lateral vibration during the transmission process, so that the lifting and lowering process of the limiting plate 5 is smooth and without shaking, and the linearity error of the fabric 4 is ≤0.2mm, ensuring the straightness of the brim seam.

[0028] This solution has the following working process: When the device is started, the fabric 4 is laid between the roller 3 and the limiting plate 5. Driving stage: The first output shaft 607 of the first servo motor 605 drives the driven shaft 603 to rotate via the synchronous belt 608, causing the connecting belt 601 to wind up or release; the connecting belt 601 pulls the limiting plate 5 vertically up and down along the sliding groove 201 via the fixing block 505, and the protruding guide 504 cooperates with the limiting groove 202 to ensure that the lifting is without deviation. At this time, the arc-shaped slot 501 of the limiting plate 5, together with the anti-slip pad 502, presses the fabric 4, and the roller 3 cooperates to release the fabric 4 to the processing area.

[0029] Positioning stage: The fabric 4 moves to the surface of the pad 701 of the base 7, and the infrared positioning device 703 scans the edge of the fabric 4 and feeds back the position signal to the control system.

[0030] Processing stage: The second output shaft 907 of the second servo motor 905 engages with the locking teeth 904 of the rear sliding frame 901, driving the movable frame 906 to slide laterally along the sliding frame 901; the movable frame 906 achieves low-resistance displacement through the pulley 903 in the groove 902, driving the lower processing component 10 to be precisely positioned to the sewing point marked by the infrared positioning device 703. After the processing component 10 completes the brim sewing according to the preset trajectory, the drive component 6 pulls the limiting plate 5 in the reverse direction to reset, entering the next cycle.

[0031] According to the above working process, the arc-shaped groove 501 of the limiting plate 5, together with the anti-slip pad 502, forms a flexible clamping surface, so that the fabric 4 is subjected to uniform force when pressed, avoiding deformation of thin materials; the double limiting structure of the connecting block 503 and the raised guide 504 ensures that the limiting plate 5 moves vertically up and down along the sliding groove 201 without deviation, and the lifting and positioning accuracy reaches ±0.1mm, which significantly improves the edge alignment consistency of the brim sewing; the first servo motor 605 drives the driven shaft 603 through the synchronous belt 608, and then pulls it through the connecting belt 601. The limiting plate 5 forms a closed-loop power transmission; the limiting ring 604 constrains axial displacement at the transmission node of the synchronous belt 608 and the connecting belt 601, eliminating the risk of belt slippage during high-speed operation, and increasing the transmission efficiency to over 95%, with the fabric 4 conveying speed reaching 1.5m / s; the universal wheel 602 provides flexible guidance to the middle of the connecting belt 601, offsetting lateral vibration during transmission, ensuring that the lifting and lowering of the limiting plate 5 is smooth and vibration-free, and the linearity error of the fabric 4 release is ≤0.2mm, ensuring the straightness of the brim seam.

[0032] Further as Figure 2 As shown, it is worth noting that the symmetrical sliding frame 901 has a groove 902 in the middle of its upper end, and several pulleys 903 are provided inside the groove 902. The rear sliding frame 901 has a locking tooth 904 on one side. The pulleys 903 in the groove 902 of the sliding frame 901 reduce the sliding friction resistance of the movable frame 906 by 80%. The locking tooth 904 of the rear sliding frame 901 provides a meshing basis for precise positioning and, together with the control component 9, achieves millimeter-level displacement control of the processing component 10.

[0033] Further as Figure 2 As shown, it is worth noting that the control component 9 also includes a second servo motor 905. The other end of the second output shaft 907 of the second servo motor 905 passes through and is slidably connected to the upper end of the movable frame 906, and engages with the locking teeth 904 of the rear sliding frame 901. The second servo motor 905 drives the movable frame 906 to move steplessly along the sliding frame 901 by directly engaging the locking teeth 904 through the second output shaft 907, with a displacement resolution of 0.05mm. The sliding connection structure between the movable frame 906 and the second output shaft 907 adapts to different workstation spacings, and the changeover response time is <0.5 seconds.

[0034] Further as Figure 4 As shown, it is worth noting that a pad 701 is fixedly connected to the upper end of the base 7. The upper end of the pad 701 is provided with at least two sets of positioning grooves 702. An infrared positioning device 703 is provided on the outside of each positioning groove 702. The modular positioning grooves 702 of the pad 701 support quick replacement of the brim mold. The infrared positioning device 703 scans the outline of the fabric 4 in real time and is linked with the processing component 10 to realize automatic calibration of the sewing start point. The positioning error is <0.3mm, and the product specification switching time is reduced to 10% of the original.

[0035] In summary: the groove 902 of the sliding frame 901 houses a pulley 903, reducing the sliding friction resistance of the movable frame 906 by 80%; the locking teeth 904 of the rear sliding frame 901 provide a meshing basis for precise positioning, and together with the control component 9, achieve millimeter-level displacement control of the processing component 10; the second servo motor 905 directly meshes with the locking teeth 904 through the second output shaft 907, driving the movable frame 906 to move steplessly along the sliding frame 901, with a displacement resolution of 0.05mm; the sliding connection structure between the movable frame 906 and the second output shaft 907 adapts to different workstation spacings, with a changeover response time of <0.5 seconds; the modular positioning groove 702 of the pad block 701 supports quick replacement of the brim mold, and the infrared positioning device 703 scans the contour of the fabric 4 in real time, linking with the processing component 10 to achieve automatic calibration of the sewing start point, with a positioning error of <0.3mm, reducing the product specification switching time to 10% of the original.
