Description

Technical Field

[0001] This utility model belongs to the field of auxiliary sewing setting technology, specifically relating to a fabric clamping component and an automatic feeding mechanism. Background Technology

[0002] In the garment sewing industry, fabric transfer and securing are crucial steps. Traditional fabric handling typically relies on manual operation or semi-automated equipment for hemming and heat sealing. However, with increasing market demand for diversified products, fabric types and sizes are becoming increasingly complex and varied. To address this challenge, existing automated fabric hemming and feeding devices employ fabric clamps of specific shapes and sizes to achieve precise fabric positioning and transfer.

[0003] Specifically, in existing technologies, fabric transfer often requires fabric clamps that resemble the shape of the fabric. Each size and shape of fabric requires a specially designed fabric clamp to ensure that the fabric can be accurately clamped and moved to a predetermined position for subsequent processing. For example, in the technical solution described in Chinese utility model patent (authorization announcement number: CN216427589U), the fabric clamp includes an upper cover plate and a lower cover plate that are hinged to each other, and is provided with a first positioning hole for gripping by a gripper cylinder. Although this design can effectively realize the gripping and movement of fabric, when dealing with fabrics of various sizes and shapes, a large number of fabric clamps of different specifications need to be prepared.

[0004] The main drawback of this method is its extremely low compatibility. Since each type of fabric requires a matching clamp, the variety of fabric clamps needed increases with the diversity of fabric sizes and shapes. This not only increases the design and manufacturing complexity of the fabric clamping components but also significantly raises production costs. Furthermore, the need to maintain and manage numerous different types of fabric clamps also increases inventory management and equipment maintenance costs for businesses, placing an additional burden on them.

[0005] In view of the above problems, there is an urgent need to develop a new type of fabric clamping component that can effectively clamp and transfer fabrics of various sizes and shapes without relying on a large number of fabric clamps of different specifications. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a clamping component and an automatic feeding mechanism for fabric, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a clamping component for fabric is proposed, including: a mounting base;

[0008] The pressing component, which is disposed on the mounting base, includes a first pressing block, a second pressing block, and a spacing adjustment component. The first pressing block and the second pressing block are both used to press on the fabric. When the first pressing block and the second pressing block are pressed on the fabric, the edges of the fabric near the first pressing block and the second pressing block are in a free state. The spacing adjustment component is used to adjust the distance between the first pressing block and the second pressing block on the mounting base to accommodate fabrics of different sizes.

[0009] The clamping member includes: a first clamping block, which is movably disposed at one end of the first pressing block away from the second pressing block, and a first clamping space is formed between the first clamping block and the first pressing block; a second clamping block, which is movably disposed at one end of the second pressing block away from the first pressing block, and a second clamping space is formed between the second clamping block and the second pressing block; both the first clamping space and the second clamping space are used to clamp the edges of the fabric in a free state.

[0010] In the aforementioned fabric clamping assembly, the spacing adjustment element is a guide rail slider structure, comprising:

[0011] A guide rail is provided on the mounting base, and both the first pressing block and the second pressing block are provided with sliders that are movably connected to the guide rail;

[0012] A first fastener is disposed on the first pressing block and movably abuts against the mounting base, for fixing or moving the first pressing block relative to the mounting base;

[0013] A second fastener is disposed on the second pressing block and movably abuts against the mounting base, for fixing or moving the second pressing block relative to the mounting base.

[0014] In the above-mentioned clamping assembly for fabric, the first fastener includes a first threaded seat disposed on the first pressing block and a first stud threadedly connected to the first threaded seat. A first handle is disposed at the end of the first stud away from the first threaded seat. A waist-shaped groove is disposed on the mounting base. One end of the first stud passes through the waist-shaped groove and is connected to the first threaded seat.

[0015] In the above-mentioned clamping assembly for fabric, the second fastener includes a second threaded seat disposed on the second pressing block and a second stud threadedly connected to the second threaded seat. One end of the second stud is provided with a second handle, and the end of the second stud away from the second handle is movably pressed against the mounting base.

[0016] In the aforementioned fabric clamping assembly, the spacing adjustment element is a motor lead screw structure, comprising:

[0017] A first motor is mounted on the mounting base, and the output end of the first motor is connected to a double-ended lead screw via a reducer.

[0018] The third threaded seat is disposed on the first pressing block and threadedly connected to the lead screw;

[0019] The fourth threaded seat is disposed on the second pressing block and threadedly connected to the lead screw. The third threaded seat and the fourth threaded seat respectively cooperate with the reverse thread section of the double-ended lead screw, and are used to drive the first pressing block and the second pressing block to move closer or further away when the lead screw rotates.

[0020] In the above-mentioned clamping assembly for fabric, a first cylinder is provided on the first pressing block, and the first clamping block is connected to the output end of the first cylinder.

[0021] The second pressing block is equipped with a second cylinder, and the second clamping block is connected to the output end of the second cylinder.

[0022] In the above-mentioned clamping assembly for fabric, a first rubber pad is provided on the end face of the pressing member facing the fabric, and a second rubber pad is provided on the end of the first clamping block and the second clamping block facing the pressing member. The first rubber pad and the second rubber pad are used to increase the friction between the first clamping space and the second clamping space and the fabric.

[0023] In the aforementioned clamping assembly for fabric, the mounting base, the first pressing block, and the second pressing block are all made of carbon fiber material to reduce the weight of the clamping assembly.

[0024] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic feeding mechanism for fabric is proposed, including the above-mentioned clamping component for fabric.

[0025] The aforementioned automatic feeding mechanism for fabric includes:

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0040] like Figures 1 to 3 As shown, a clamping assembly for fabric according to the present invention includes: a mounting base 1, a pressing member 2, and a clamping member 6.

[0041] Specifically, the pressing component 2, which is mounted on the mounting base 1, includes a first pressing block 3, a second pressing block 4, and a spacing adjustment component 5. Both the first pressing block 3 and the second pressing block 4 are used to press on the fabric, and when the first pressing block 3 and the second pressing block 4 are pressed on the fabric, the edges of the fabric near the first pressing block 3 and the second pressing block 4 are in a free state. The spacing adjustment component 5 is used to adjust the distance between the first pressing block 3 and the second pressing block 4 on the mounting base 1 to accommodate fabrics of different sizes. The clamping component 6 includes: a first clamping block 7, which is movably disposed at the end of the first pressing block 3 away from the second pressing block 4, forming a first clamping space between the first clamping block 7 and the first pressing block 3; and a second clamping block 8, which is movably disposed at the end of the second pressing block 4 away from the first pressing block 3, forming a second clamping space between the second clamping block 8 and the second pressing block 4. Both the first clamping space and the second clamping space are used to clamp the edges of the fabric in a free state.

[0042] The first pressing block 3 and the second pressing block 4 are preferably elongated structures used to press against the two opposite long sides of the fabric. Before starting work, the distance between the first pressing block 3 and the second pressing block 4 is adjusted according to the size of the fabric using the spacing adjustment piece 5. The standard adjustment is generally that after the first pressing block 3 and the second pressing block 4 are pressed onto the fabric, the distance from the edge of the fabric near the first pressing block 3 and the second pressing block 4 to the distance between the first pressing block 3 and the second pressing block 4 is approximately 10 mm.

[0043] During operation, the pressing component 2 first presses against the surface of the fabric. At this time, the first pressing block 3 and the second pressing block 4 press the fabric tightly, and the edges of the fabric near the first pressing block 3 and the second pressing block 4 are exposed outside the pressing space enclosed by them and are in a free state. After the pressing component 2 completes the pressing, the first clamping block 7 and the second clamping block 8 move towards the first pressing block 3 and the second pressing block 4 respectively, so that the width of the first clamping space and the second clamping space gradually decreases. During the movement of the first clamping block 7 and the second clamping block 8, they first contact the edge of the fabric and push the edge of the fabric to converge towards the center of the fabric, so that the edge portion of the fabric near the first pressing block 3 and the second pressing block 4 is clamped between the first pressing block 3 and the first clamping block 7, and between the second pressing block 4 and the second clamping block 8, ultimately achieving a stable fixation of the fabric on the clamping assembly.

[0044] In this solution, the first clamping block 7, which is movably connected to the first pressing block 3, and the second clamping block 8, which is movably connected to the second pressing block 4, effectively clamp the fabric. At the same time, the distance between the first pressing block 3 and the second pressing block 4 can be adjusted by the spacing adjustment component 5, thereby adapting to fabrics of different sizes. This avoids the problem of needing to prepare fabric clamping plates of various specifications in traditional technology, and improves the versatility and practicality of the clamping components.

[0045] Furthermore, in one embodiment, the spacing adjustment member 5 is a guide rail slider structure, including: a guide rail 9, which is disposed on the mounting base 1, and sliders 10 movably connected to the guide rail 9 are disposed on the first pressing block 3 and the second pressing block 4; a first fastener 11, which is disposed on the first pressing block 3 and movably abuts against the mounting base 1, for fixing or moving the first pressing block 3 relative to the mounting base 1; and a second fastener 12, which is disposed on the second pressing block 4 and movably abuts against the mounting base 1, for fixing or moving the second pressing block 4 relative to the mounting base 1.

[0046] When adjusting the distance between the first pressing block 3 and the second pressing block 4, firstly, the fixed connection between the first pressing block 3 and the mounting base 1, and between the second pressing block 4 and the mounting base 1, is loosened using the first fastener 11 and the second fastener 12, so that both the first pressing block 3 and the second pressing block 4 are movable relative to the mounting base 1. Then, the distance between the first pressing block 3 and the second pressing block 4 is adjusted by adjusting the position of the slider 10 on the guide rail 9. After adjustment, the first pressing block 3 and the second pressing block 4 are then fixed in the set position using the first fastener 11 and the second fastener 12.

[0047] In this solution, a guide rail 9 and slider 10 structure are used to achieve spacing adjustment, ensuring the stability and positioning accuracy of the first pressing block 3 and the second pressing block 4 during the movement process, thereby improving the working stability and reliability of the clamping component.

[0048] It is worth mentioning that when adjusting the distance between the first pressing block 3 and the second pressing block 4, one of the first pressing block 3 and the second pressing block 4 can be fixedly connected to the mounting base 1, and then the distance between the first pressing block 3 and the second pressing block 4 can be adjusted by adjusting the position of the other pressing block relative to the mounting base 1.

[0049] Furthermore, the first fastener 11 includes a first threaded seat 13 disposed on the first pressing block 3, and a first stud 14 threadedly connected to the first threaded seat 13. A first handle 15 is disposed at the end of the first stud 14 away from the first threaded seat 13. A waist-shaped groove 16 is disposed on the mounting base 1. One end of the first stud 14 passes through the waist-shaped groove 16 and is connected to the first threaded seat 13. One end of the first handle 15 is movably pressed against the end face of the mounting base 1.

[0050] In the initial state, one end of the first handle 15 is pressed against the end face of the mounting base 1, keeping the first pressing block 3 fixedly connected to the mounting base 1. When it is necessary to adjust the position of the first pressing block 3 on the mounting base 1, firstly, by rotating the first handle 15, the distance between the first handle 15 and the mounting base 1 is increased. At this time, the first handle 15 separates from the mounting base 1, and the first pressing block 3 is in a movable state relative to the mounting base 1. The waist-shaped groove 16 is used to provide clearance for the movement of the first stud 14 when the first pressing block 3 moves relative to the mounting base 1. After adjusting the position of the first pressing block 3, the first handle 15 is rotated in the opposite direction to fix the first pressing block 3 back to the mounting base 1.

[0051] In this design, the first pressing block 3 can be firmly fixed to the mounting base 1 at any position by the cooperation of the first stud 14 and the first threaded seat 13, preventing loosening and thus ensuring the working stability of the clamping assembly. In addition, the first handle 15 makes the adjustment of the state of the first pressing block 3 more convenient and intuitive.

[0052] It is worth mentioning that the second fastener 12 includes a second threaded seat 17 disposed on the second pressing block 4, and a second stud 18 threadedly connected to the second threaded seat 17. One end of the second stud 18 is provided with a second handle 19, and the end of the second stud 18 away from the second handle 19 is movably pressed against the mounting base 1.

[0053] In the initial state, one end of the second stud 18 is pressed against the mounting base 1. The friction between the second stud 18 and the mounting base 1 keeps the second pressing block 4 fixed to the mounting base 1. Alternatively, two second fasteners 12 can be used, positioned opposite each other. The second studs 18 on these two fasteners press against opposite side walls of the mounting base 1, thus firmly fixing the second pressing block 4 to the mounting base 1. When the second handle 19 is rotated, the end of the second stud 18 separates from the mounting base 1, allowing the second pressing block 4 to switch to a movable state for easy position adjustment.

[0054] Similar to the first fastener 11, the second fastener 12 provides effective fixation for the second pressing block 4, ensuring that both pressing blocks can work stably and avoiding clamping failure due to loosening on one side.

[0055] In another embodiment (not shown in the figure), the spacing adjustment component 5 is a motor lead screw structure, including: a first motor, which is mounted on the mounting base 1, and the output end of the first motor is connected to a double-ended lead screw through a reducer; a third threaded seat, which is mounted on the first pressing block 3 and threadedly connected to the lead screw; and a fourth threaded seat, which is mounted on the second pressing block 4 and threadedly connected to the lead screw. The third threaded seat and the fourth threaded seat respectively cooperate with the reverse thread section of the double-ended lead screw, and are used to drive the first pressing block 3 and the second pressing block 4 to move closer or further away when the lead screw rotates.

[0056] The spacing adjustment is achieved by using a first motor to drive the lead screw, eliminating the need for manual intervention, thus improving the level of automation and making it suitable for large-scale continuous production applications.

[0057] It is worth mentioning that the first pressing block 3 is equipped with a first cylinder 20, and the first clamping block 7 is connected to the output end of the first cylinder 20; the second pressing block 4 is equipped with a second cylinder 21, and the second clamping block 8 is connected to the output end of the second cylinder 21.

[0058] The cylinder-driven clamping block design makes the clamping action faster and more controllable, and can adjust the clamping force in real time according to the changes in fabric thickness to ensure a firm grip.

[0059] Furthermore, a first rubber pad 22 is provided on the end face of the pressing member 2 facing the fabric, and a second rubber pad 23 is provided on the end of the first clamping block 7 and the second clamping block 8 facing the pressing member 2. The first rubber pad 22 and the second rubber pad 23 are used to increase the friction between the first clamping space and the second clamping space and the fabric.

[0060] The presence of the first rubber pad 22 and the second rubber pad 23 increases the friction of the contact surface, which helps to clamp the fabric edge more firmly and ensures the stability of the clamping process. At the same time, the rubber pads can prevent metal parts from directly contacting the fabric, preventing scratches or wear caused by friction or pressure, thereby effectively protecting the quality of the fabric.

[0061] Preferably, the mounting base 1, the first pressing block 3, and the second pressing block 4 are all made of carbon fiber material to reduce the weight of the clamping assembly. Carbon fiber material has low density and high strength, which significantly reduces the weight of the entire clamping assembly, facilitating handling and installation. It also reduces the inertial load on moving parts, which helps improve operating speed and stability.

[0062] This solution also proposes an automatic feeding mechanism for fabric, including the aforementioned fabric clamping component.

[0063] More specifically, the automatic feeding mechanism includes: a linear guide rail 24; a second motor 25, which is driven and connected to the linear guide rail 24; a connecting seat 26, which is disposed at the output end of the second motor 25, and the second motor 25 is used to drive the connecting seat 26 to rotate; and a third cylinder 27, which is vertically disposed on the connecting seat 26, and the mounting seat 1 is connected to the output end of the third cylinder 27.

[0064] During operation, the combination of linear guide 24, second motor 25 and third cylinder 27 forms a three-dimensional conveying platform, realizing the movement of the clamping component in the vertical, horizontal and forward and backward directions in space, thereby completing the automatic conveying process of the fabric clamped by the clamping component.
