Description

Technical Field

[0001] This utility model relates to the field of fabric production and processing technology, specifically to an automatically adjustable fabric handling tool. Background Technology

[0002] In the garment manufacturing process, there is a great deal of need for fabric handling or transfer. Because fabric is soft and breathable, it cannot be handled by suction cups. Finger-grip tools are also difficult to effectively separate soft fabrics. Therefore, garment manufacturing is difficult to automate and is currently mainly done manually.

[0003] Currently, there are some needle-punched suction cup products on the market. Although they can transport fabric, they require manual adjustment of the needle height when adapting to fabrics of different thicknesses. This makes it difficult to operate automatically online, resulting in a low degree of automation. In addition, the needle height adjustment is not precise and is difficult to adjust. After adjusting to different heights, the relative position of the needle tips may not be fixed, leading to unreliable fabric gripping. Therefore, an automatically adjustable fabric transport tool is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the aforementioned technical problems, this invention provides an automatically adjustable fabric handling tool. This solution solves the problem mentioned in the background section that while some needle-punched suction cup products on the market can handle fabrics, they require manual adjustment of the needle height when handling fabrics of different thicknesses, making online automatic operation difficult and resulting in low automation. Furthermore, the needle height adjustment is inaccurate and difficult, leading to inconsistent needle tip positions after adjusting to different heights, resulting in unreliable fabric gripping performance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatically adjustable fabric handling tool includes a fixed housing.

Two symmetrically distributed needle assemblies are provided at the front and rear ends of the movable seat. A servo motor is fixedly installed on the upper end of the fixed housing. The output end of the servo motor passes through the upper end of the fixed housing and is fixedly connected to a lead screw. A contact platform is threaded to the outer surface of the lead screw. Two symmetrically distributed fixed guide pins are fixedly connected between the inner walls of the front and rear sides of the fixed housing.

[0007] The needle assembly includes a needle block slider. The lower end of the needle block slider is fixedly connected to a plurality of evenly distributed fine needles, all of which are inclined. The front end of the needle assembly has two symmetrically distributed sliding grooves, and the front end of the needle block slider is provided with a guide groove below the sliding grooves.

[0008] Preferably, each set of sliding blocks consists of two blocks, with the two blocks slidably connected to the interiors of the two grooves respectively.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figures 1-6 As shown, an automatically adjustable fabric handling tool includes a fixed housing 1. A base plate 2 is fixedly connected to the lower end of the fixed housing 1. A through groove 4 is opened through the lower end of the base plate 2. Two symmetrically distributed cylinders 3 are fixedly installed on the upper end of the fixed housing 1. A piston body 301 is slidably connected to the inner side of the cylinders 3. A guide rod body 304 is fixedly connected to the lower end of the piston body 301. A movable seat 7 is fixedly connected to the lower end of the guide rod body 304. Two sets of sliding blocks 10 are fixedly connected to both the front and rear ends of the movable seat 7. Two symmetrically distributed needle assemblies 6 are provided at both the front and rear ends of the movable seat 7. A servo motor 8 is fixedly installed on the upper end of the fixed housing 1. The output end of the servo motor 8 passes through the upper end of the fixed housing 1 and is fixedly connected to a lead screw 9. A contact platform 5 is threadedly connected to the outer surface of the lead screw 9. Two symmetrically distributed fixed guide pins 12 are fixedly connected between the inner walls of the front and rear sides of the fixed housing 1.

[0027] The needle assembly 6 includes a needle group slider 601. The lower end of the needle group slider 601 is fixedly connected to a plurality of evenly distributed fine needles 602. The plurality of fine needles 602 are all inclined. The front end of the needle assembly 6 has two symmetrically distributed sliding grooves 603. The front end of the needle group slider 601 is provided with a guide groove 604 below the sliding grooves 603.

[0028] Furthermore, each set of sliding blocks 10 consists of two blocks, and the two sliding blocks 10 are slidably connected to the interior of the two sliding grooves 603 respectively.

[0029] Furthermore, the left fixed guide pin 12 is slidably connected to the inside of the two left guide grooves 604, and the right fixed guide pin 12 is slidably connected to the inside of the two right guide grooves 604.

[0030] Furthermore, the lower end of the contact platform 5 is provided with multiple evenly distributed limiting grooves 501, and the fine needle 602 is slidably connected to the inside of the limiting grooves 501.

[0031] Furthermore, by introducing high-pressure gas into the upper inner cavity of cylinder 3, the piston body 301 can push the guide rod body 304 downward. At this time, the moving seat 7 pulls the needle assembly slider 601 downward through the sliding block 10. The guide groove 604 and the fine needles 602 are both inclined towards the contact platform 5. When the needle assembly slider 601 moves downward, the fixed guide pin 12, in conjunction with the guide groove 604, can drive the needle assembly 6 to slide along the fixed guide pin 12, so that the fine needles 602 extend out from the limiting groove 501. The tips of the two sets of fine needles 602 face each other and pierce into the fabric, thereby realizing the grasping of the fabric. During the movement of the needle assembly slider 601, the sliding block 10 will slide horizontally inside the sliding groove 603 to adapt to the movement of the needle assembly slider 601. Conversely, when high-pressure air is introduced into the lower inner cavity of cylinder 3, the fine needles 602 retract and release the grasped fabric.

[0032] Furthermore, the contact platform 5 supports the bottom surface of the fabric, and the limiting groove 501 cooperates with the fine needle 602 to maintain a stable insertion angle. The servo motor 8 drives the lead screw 9 to rotate, which can drive the contact platform 5 to move up and down. While keeping the needle height constant, the height of the contact platform 5 can be adjusted to adapt to the gripping of fabrics of different thicknesses.

[0033] Furthermore, both the servo motor 8 and the cylinder 3 are electrically connected to an external control device. After preset values ​​are obtained from the external control device, the control system can control the servo motor 8 and the cylinder 3 to run automatically online. The needle height is automatically adjusted according to the set parameters. The automation level is high and the height adjustment is controlled by the servo motor 8, resulting in high adjustment accuracy. After adjusting to different heights, the operation of the cylinder 3 can keep the guide rod body 304 in a certain position, thus fixing the relative position of the needle tip and improving the fabric gripping effect.

[0034] Furthermore, two symmetrically distributed grooves are provided on the inner top of the fixed housing 1. Guide rods 11 are slidably connected inside the grooves. The lower end of the guide rods 11 is fixedly connected to the upper end of the contact platform 5. The movable seat 7 is slidably connected to the outer surface of the two guide rods 11.

[0035] Furthermore, the guide rod 11 guides and limits the contact platform 5, thereby ensuring the stable movement of the contact platform 5.

[0036] Furthermore, a piston sealing ring 302 is fitted on the outer surface of the piston body 301, and a guide rod sealing ring 303 is fitted on the outer surface of the guide rod body 304. The piston sealing ring 302 and the guide rod sealing ring 303 divide the interior of the cylinder 3 into an upper inner cavity and a lower inner cavity. The upper part of the piston sealing ring 302 is the upper inner cavity, and the area between the piston sealing ring 302 and the guide rod sealing ring 303 is the lower inner cavity.

[0037] Working principle: In use, the contact platform 5 is placed against the surface of the fabric, and then high-pressure gas is introduced into the upper inner cavity of the cylinder 3, causing the piston body 301 to push the guide rod body 304 downward. At this time, the moving seat 7 pulls the needle group slider 601 downward through the sliding block 10. As the needle group slider 601 moves downward, the fixed guide pin 12, in conjunction with the guide groove 604, can drive the needle assembly 6 to slide along the fixed guide pin 12, so that the fine needles 602 extend out from the limiting groove 501. The tips of the two sets of fine needles 602 face each other and pierce into the fabric, thereby realizing the grasping of the fabric. After the fabric is moved to the target position, high-pressure air is introduced into the lower inner cavity of the cylinder 3, which will cause the fine needles 602 to retract and release the grasped fabric.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
