Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and particularly relates to a bead crusher. Background Art

[0002] In the fashion industry, tulle fabric is widely used in high-end clothing such as evening gowns and wedding dresses due to its lightness, transparency and elegance. As a type of tulle fabric, beaded fabric itself is rich in elegance and luxury and is often used to enhance the decorative effect of clothing. By embroidering beads and sequins on the tulle fabric, it can not only increase the visual appeal of the clothing but also greatly enhance the noble temperament of the wearer.

[0003] However, for traditional beaded fabrics, the beads are hard and protrude from the fabric. When pressing the fabric with the presser foot of a sewing device, the beads will get stuck between the fabric and the presser foot. Due to this reason, beaded fabrics are not suitable for sewing devices. However, for aesthetic purposes and to prevent the fabric from fraying or cracking, the edges of the beaded fabric need to be overlocked after cutting. The current solution is to remove the embroidered beads within a 2 cm width range at the edges of the beaded fabric pieces to meet the sewing requirements of the overlock machine. The process of removing the embroidered beads generally involves laying the fabric on a flat and clean surface and breaking the embroidered beads by hammering with a hammer or a similar tool. This manual hammering method for removing beads is inefficient and costly, and it is difficult to meet the requirements of mass production. Moreover, during the hammering process, the embroidered beads and the fabric are both stressed. While the embroidered beads are broken, the tulle fabric is also easily damaged by the knocking impact and the remaining beads, resulting in a large amount of fabric damage, increasing the production cost and reducing the fabric utilization rate.

[0004] Therefore, there is a need to develop a bead crusher to overcome the deficiencies in current practical applications. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a bead crusher with high bead crushing efficiency and capable of effectively avoiding stress on the fabric during the bead crushing process, so as to remove the embroidered beads without damaging the fabric and meet the sewing requirements.

[0009] In a preferred embodiment, the height adjustment device includes an adjustment frame, a lead screw, and a lead screw seat. The adjustment frame is mounted on the upper end of the main support mechanism. The two ends of the lead screw are rotatably connected to the upper and lower ends of the adjustment frame, respectively. The lead screw seat is threadedly connected to the lead screw. A handwheel is connected to the upper end of the lead screw after passing through the upper end of the adjustment frame. An automatic clamp is mounted on the lead screw seat. At least one guide rod is mounted on the adjustment frame, and the guide rod is slidably sleeved with the lead screw seat.

[0010] In a preferred embodiment, the bottom of the adjusting frame is provided with at least one stop adjusting member. The first end of the stop adjusting member has a strip-shaped opening extending along its length direction. The stop adjusting member is horizontally movable to the adjusting frame through the strip-shaped opening. Furthermore, the second end of the stop adjusting member has a stop portion parallel to the moving direction of the fabric.

[0011] In a preferred embodiment, the automatic clamp includes a pneumatic clamp located directly above the bead separation device, with its upper end fixedly connected to the lead screw seat. The pneumatic clamp is connected to an external air supply and exhaust device via a pipeline, which is equipped with a solenoid valve and an air pressure regulating device.

[0012] In a preferred embodiment, a locking member is provided on the top of the adjusting frame. One end of the locking member is fixedly connected to the adjusting frame, and the other end of the locking member is provided with a locking port through which the upper end of the lead screw passes. A locking bolt is provided on the locking member. One end of the locking bolt is threaded to one side of the locking port, and the other end of the locking bolt passes through the locking port and the locking member in sequence and is connected to a wrench.

[0013] In a preferred embodiment, a feeding mechanism is also included, the feeding mechanism comprising a pressure roller connected to a power device for driving its axial rotation.

[0014] In a preferred embodiment, the power unit includes a support frame, on which a feeding motor is mounted. The feeding motor is connected to the pressure roller via a pulley set.

Moreover, the automatic bead clamping device crushes the embroidered beads in the horizontal direction, and its clamping direction is parallel to the moving direction of the beaded fabric. This avoids the automatic bead clamping device from contacting the fabric during the crushing process, effectively preventing pressure from acting on the fabric, thereby reducing fabric damage and lowering production costs.

[0023] Reference Figures 1-7 A bead crusher, comprising: Main support structure 1; An automatic bead-clamping device 2 is located at the upper end of the main support mechanism 1 and is used to clamp and break the embroidered beads from the horizontal direction. The bead separation device 3 is located at the lower end of the main support mechanism 1 and is located directly below the automatic bead clamping device 2. It is used to lift the embroidery beads so that the embroidery beads enter the biting range of the automatic bead clamping device 2.

[0024] In this embodiment, the main support mechanism 1 serves as a support structure for fixing the automatic bead clamping device 2 and the bead separation device 3 above the work platform. In actual use, the beaded fabric passes horizontally through the bead separation device 3. The embroidered beads on the fabric are lifted by the bead separation device 3, and all or most of the embroidered beads enter the biting range of the automatic bead clamping device 2. The embroidered beads can be crushed by the automatic bead clamping device 2, achieving the effect of efficiently removing the embroidered beads, thereby meeting the needs of subsequent sewing. Furthermore, the automatic bead clamping device 2 crushes the embroidered beads from a horizontal direction, and its clamping direction is parallel to the moving direction of the beaded fabric. This prevents the automatic bead clamping device 2 from contacting the fabric during the crushing of the embroidered beads, effectively preventing the pressure from crushing the embroidered beads from acting on the fabric, thereby reducing fabric damage and lowering production costs.

[0025] Reference Figure 1-3 and Figure 5 The bead separation device 3 includes a support plate 31 and two pressure rods 32. The support plate 31 is located directly below the clamping opening of the automatic bead clamping device 2, and the height of the top surface of the support plate 31 is greater than the height of the bottom surface of the pressure rods 32. The two pressure rods 32 are located on both sides of the support plate 31, and one end of the support plate 31 and the two pressure rods 32 are connected to the main support mechanism 1.

[0026] Specifically, as the beaded fabric passes horizontally through the bead separation device 3, it sequentially passes through the gap between the working platform and the first pressure bar 32, above the support plate 31, and the gap between the working platform and the second pressure bar 32. Since the height of the top surface of the support plate 31 is greater than the height of the bottom surface of the pressure bar 32, the beaded fabric is in a state of being high in the middle and low on both sides when passing through the bead separation device 3. When the embroidered bead moves to the top of the support plate 31, the embroidered bead will be lifted by the support plate 31, while the fabric on both sides of the embroidered bead will be pressed down by the pressure bar 32, so that the embroidered bead protrudes from the fabric surface. While the embroidered bead is lifted into the biting range of the automatic bead clamping device 2, the embroidered bead and the fabric are effectively separated, further preventing the automatic bead clamping device 2 from clamping the fabric.

[0027] In a preferred embodiment, one end of the support plate 31 and the two pressure rods 32 are threaded to the main support mechanism 1 or detachably connected to the main support mechanism 1 by screws, which facilitates maintenance and replacement.

[0028] Reference Figure 1 The automatic bead clamping device 2 includes an automatic clamp 21, which is located directly above the bead separation device 3, and is connected to the main support mechanism 1 via a height adjustment device 22.

[0029] Reference Figure 2 and Figure 3 The height adjustment device 22 includes an adjustment frame 221, a lead screw 222, and a lead screw seat 223. The adjustment frame 221 is located at the upper end of the main support mechanism 1. The two ends of the lead screw 222 are rotatably connected to the upper and lower ends of the adjustment frame 221, respectively. The lead screw seat 223 is threadedly connected to the lead screw 222. The upper end of the lead screw 222 passes through the upper end of the adjustment frame 221 and is connected to a handwheel 224. The automatic clamp 21 is mounted on the lead screw seat 223. At least one guide rod 225 is mounted on the adjustment frame 221, and the guide rod 225 is slidably sleeved with the lead screw seat 223.

[0030] Rotating the screw 222 by handwheel 224 will drive the screw seat 223 to move up and down, which in turn drives the automatic clamp 21 to move up and down, thereby adjusting the height of the automatic clamp 21 to fit fabrics of different thicknesses and embroidered beads of different sizes.

[0031] In a preferred embodiment, there are two guide rods 225, which are arranged in parallel on both sides of the lead screw 222.

[0032] Reference Figure 1-3 and Figure 5The bottom of the adjusting frame 221 is provided with at least one stop adjusting member 4. The first end of the stop adjusting member 4 has a strip-shaped opening 401 extending along its length direction. The stop adjusting member 4 is horizontally movably connected to the adjusting frame 221 through the strip-shaped opening 401. The second end of the stop adjusting member 4 has a stop portion 402 parallel to the moving direction of the fabric, which is used to block the edge of the fabric and achieve a positioning effect.

[0033] The stop adjustment component 4 is threadedly connected to the adjustment frame 221 or the main support mechanism 1 after passing through the strip opening 401 via a positioning bolt (not shown). Loosening the positioning bolt allows the stop adjustment component 4 and the strip opening 401 to slide relative to the positioning bolt along their length direction, thereby adjusting the relative position of the stop part 402 in the projection plane below the automatic clamp 21. This allows control of the bead breaking area of ​​the automatic clamp 21 to meet the needs of removing embroidered beads of different widths. Tightening the positioning bolt causes its head to press tightly against the stop adjustment component 4, thus fixing the position of the stop adjustment component 4.

[0034] In a preferred embodiment, the stop part 402 is integrally formed with the stop adjustment member 4 and is formed by bending the second end of the stop adjustment member 4. It can be understood that the stop part 402 can also be an external part, which is fixed to the second end of the stop adjustment member 4 by welding, fusion or bonding.

[0035] In a preferred embodiment, the number of stop adjustment members 4 is two, and the two stop adjustment members 4 are symmetrically located on both sides of the bead separation device 3, resulting in better positioning effect.

[0036] Reference Figure 1-3 The automatic clamp 21 includes a pneumatic clamp 211, which is located directly above the bead separation device 3. The upper end of the pneumatic clamp 211 is fixedly connected to the lead screw seat 223. The pneumatic clamp 211 is connected to an external air supply and exhaust device through a pipeline. The pipeline is equipped with a solenoid valve 212 and an air pressure regulating device 213.

[0037] As an optional embodiment, the solenoid valve 212 is a high-frequency solenoid valve. Under the control of the microprocessor, the solenoid valve 212 automatically opens and closes, thereby controlling the opening and closing of the pipeline and the inlet and outlet of gas, and thus controlling the opening and closing of the pneumatic clamp 211. The pressure regulating device 213 is a pressure regulating filter, which has both pressure regulating and filtering functions. For example, the BFR series pressure regulating filter from Taiwan's CHELIC brand can be used.

[0038] It is understood that the automatic clamp 21 can also be an electric clamp or a hydraulic clamp. The structure and working principle of the pneumatic clamp 211, electric clamp, and hydraulic clamp are all existing technologies. For specific structures and working principles, please refer to a pneumatic clamp with application number CN201220706027.9, a novel servo electric gripper structure with application number CN202323045354.1, and a hydraulic clamp for forging with application number CN200820035019.X, etc., which will not be elaborated here.

[0039] Reference Figure 4 A locking member 5 is provided on the top of the adjusting frame 221. One end of the locking member 5 is fixedly connected to the adjusting frame 221, and the other end of the locking member 5 is provided with a locking port 501 through which the upper end of the lead screw 222 passes. A locking bolt (not shown) is provided on the locking member 5. One end of the locking bolt is threaded to one side of the locking port 501, and the other end of the locking bolt passes through the locking port 501 and the locking member 5 in sequence and is connected to a wrench 502.

[0040] The locking member 5 is made of a material capable of elastic deformation. One end, fixedly connected to the adjusting bracket 221, is a fixed end, and the other end is a free end. The locking port 501 separates the free end of the stop adjusting member 4 into a first part and a second part. The first part has a threaded hole, and the second part has a threaded hole or a through hole. One end of the locking bolt passes through the threaded hole or through hole in the second part and, after passing the locking port 501, is threadedly connected to the threaded hole in the first part. By turning the locking bolt with a wrench, the first and second parts... Partial deformation occurs and the distance between the two parts decreases, that is, the opening of the locking port 501 becomes smaller, thereby clamping the upper end of the lead screw 222 and fixing the lead screw 222, thereby fixing the height of the lead screw seat 223 and the automatic clamp 21; by reversing the locking bolt with a wrench, the first part and the second part deform and the distance between them increases, that is, the opening of the locking port 501 becomes larger, thereby loosening the upper end of the lead screw 222. At this time, the lead screw 222 can be rotated by the handwheel 224, thereby changing the height of the lead screw seat 223 and the automatic clamp 21.

[0041] Reference Figure 1 The embodiments of the present invention also include a feeding mechanism, which includes a pressure roller 6. The pressure roller 6 is connected to a power device 7 for driving its axial rotation, thereby enabling the fabric pressed between the pressure roller 6 and the work platform to move, resulting in a higher degree of automation.

[0042] In a preferred embodiment, the pressure roller 6 is a rubber roller.

[0043] Reference Figure 6The power unit 7 includes a bracket 71, on which a feeding motor 72 is mounted. The feeding motor 72 is connected to the pressure roller 6 via a pulley set 73, thereby driving the pressure roller 6 to rotate axially, which in turn drives the fabric pressed between the pressure roller 6 and the work platform to move.

[0044] In a preferred embodiment, the outer side of the pulley assembly 73 is provided with a protective cover.

[0045] Reference Figure 7 The bracket 71 is provided with a rocker arm 74, and the two ends of the rocker arm 74 are rotatably connected to the bracket 71 and the pressure roller 6 respectively. The bracket 71 is also provided with a lifting motor 75, and the output end of the lifting motor 75 is eccentrically connected to a shock absorber 77 through a flange 76. The two ends of the shock absorber 77 are rotatably connected to the flange 76 and the rocker arm 74 respectively.

[0046] The shock absorber 77 can effectively support the rocker arm 74 near the pressure roller 6, so that the pressure roller 6 can press down on the fabric, while when the embroidery bead passes under the pressure roller 6, the rocker arm 74 is allowed to swing slightly upward and the pressure roller 6 is raised slightly, so that the embroidery bead can pass through better and can effectively prevent the embroidery bead from being crushed.

[0047] When the lifting motor 75 is started, it drives the shock absorber 77 to move eccentrically through the flange 76, which can drive the rocker arm 74 to swing up and down and the pressure roller 6 to rise and fall, thereby adjusting the distance between the pressure roller 6 and the work platform to adapt to fabrics of different thicknesses.

[0048] Reference Figure 1-3 An adjustable protective stop 8 is provided on the side of the automatic clamp 21 away from the main support mechanism 1. The protective stop 8 includes at least one swing rod 81. One end of the swing rod 81 is rotatably connected to the automatic clamp 21 by an adjusting bolt (not shown), and the other end of the swing rod 81 is connected to a baffle 82.

[0049] In a preferred embodiment, the baffle 82 is made of a transparent material to facilitate observation of the automatic clamp 21 crushing the embroidered beads.

[0050] In a preferred embodiment, the present invention further includes a dust collection device (not shown), the suction port of which is located near the clamping jaws of the automatic clamp 21, for collecting the broken beads into a dust collection bin. The structure and working principle of the dust collection device are existing technologies. For details on the structure and working principle, please refer to the automatic dust collection device for a stone crusher with application number CN201220716236.1, which will not be elaborated here.

[0051] Working principle of this invention: In use, first start the lifting motor 75, which sequentially pulls the pressure roller 6 upward through the flange 76, shock absorber 77, and rocker arm 74, creating a gap between the pressure roller 6 and the work platform. Then, the operator places the front end of the fabric between the pressure roller 6 and the work platform. Simultaneously, the fabric, located at the bead separation device 3, is sequentially placed between the work platform and the first pressure rod 32, above the support plate 31, and between the work platform and the second pressure rod 32. Then, start the lifting motor 75 again, causing the pressure roller 6 to descend until the front end of the fabric is pressed between the pressure roller 6 and the work platform. Then, the automatic clamp 21 and the feeding motor 72 are started. Driven by the feeding motor 72, the pressure roller 6 rotates axially and pulls the fabric to move horizontally. At the same time, the jaws of the pneumatic clamp 211 repeatedly open and close. When the fabric moves the embroidery beads to the tray 31, all or most of the embroidery beads enter the biting range of the jaws of the pneumatic clamp 211. The embroidery beads will be crushed, thereby efficiently removing the embroidery beads to meet the needs of subsequent sewing. It can also avoid the automatic bead clamping device 2 from contacting the fabric, reduce the force on the fabric, and achieve the effect of removing the embroidery beads without damaging the fabric.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
