Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a fabric cutting and flattening device. Background Technology

[0002] Clothing is a general term for clothes, shoes, and accessories, but it mainly refers to clothing. In national standards, clothing is defined as: sewn products worn on the human body for protection and decoration, also known as clothes. In clothing processing, fabric needs to be cut to the appropriate size. Currently, cutting is usually done manually. The fabric is placed on a workbench and cut with scissors or a cutting knife. This method is inefficient and prone to wrinkles and unevenness during the cutting process, resulting in inaccurate cutting dimensions, difficulty in cutting with scissors, and easy waste of fabric.

[0003] For example, a fabric cutting and flattening device for garment processing disclosed in Chinese patent literature (publication number: CN219824695U) uses a sliding block, a lifting block, a transmission plate, and a lower clamping plate in combination. This allows the user to fix both sides of the fabric through the lower and upper clamping plates, and then step down on the pedal. The moving block drives the lifting block to move downward through the connecting rod, and the lifting block drives the sliding block to move outward through the transmission plate. The lower and upper clamping plates flatten the fabric, thereby reducing wrinkles in the fabric during the cutting process, making it easier for the user to cut with scissors, and improving the cutting accuracy of the fabric.

[0004] However, when the fabric is stretched by pressing down on the pedal, the elasticity of different fabrics varies. If the elasticity is poor, the fabric may be overstretched and damaged. Furthermore, the stepping posture must be maintained throughout the cutting process. Maintaining the same posture for a long time can lead to leg muscle fatigue, resulting in unstable stepping force, which can cause the fabric to become loose and affect the cutting accuracy. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when flattening and cutting fabric, manual labor is required, and the force applied by stepping is unstable, which can easily lead to fabric tearing and damage and reduced cutting accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fabric cutting and flattening device includes a cutting table, and a flattening mechanism is provided above the cutting table;

[0008] The flattening mechanism includes a mounting block, the lower end of which is fixedly connected to the upper end of the cutting table. A moving groove is provided on the front of the mounting block. A servo motor is fixedly mounted on one side of the mounting block. A bidirectional lead screw is fixedly mounted on the output shaft of the servo motor through a coupling. One end of the bidirectional lead screw passes through the interior of the moving groove and is rotatably connected to the inner wall of one side of the moving groove through a bearing. The external threads of the bidirectional lead screw are connected to symmetrically distributed threaded blocks.

[0009] A convenient clamping mechanism is provided above the cutting table.

[0010] Preferably, the outer side of the threaded block is slidably sleeved with the inner wall of the movable groove, a support block is fixedly connected to the front side of the threaded block, and a slot is provided on the front side of the support block.

[0011] Preferably, a first anti-slip pad is fixedly connected to the upper end of the support block, a support groove is provided at the upper end of the cutting table, and symmetrically distributed support sliders are slidably connected to the inner wall of the support groove. The upper end of the support slider is fixedly connected to the lower end of the support block.

[0012] Preferably, the convenient clamping mechanism includes supports, the lower ends of the two supports are symmetrically distributed and fixedly connected to the upper ends of the two support blocks respectively, and the inner walls on both sides of the supports are rotatably connected to rotating rods through bearings.

[0013] Preferably, a rotating clamping block is fixedly sleeved on the outside of the rotating rod, and limit rods are fixedly connected to the inner walls on both sides of the support. Symmetrically distributed torsion springs are fixedly connected to both sides of the rotating clamping block.

[0014] Preferably, one end of each of the two torsion springs is fixedly connected to the inner walls of both sides of the support, the lower end of the rotating clamp is fixedly connected to a second anti-slip pad, the interior of the rotating clamp is provided with an installation cavity, and a sliding block is slidably sleeved on the inner wall of the installation cavity.

[0015] Preferably, a return spring is fixedly connected to the back of the sliding block, one end of the return spring is fixedly connected to the rear inner wall of the mounting cavity, and a U-shaped plug is fixedly connected to the front of the sliding block, one end of the U-shaped plug passing through the rotating clamp and movably inserted into the inner wall of the slot.

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

[0017] In this invention, the servo motor and bidirectional lead screw in the flattening mechanism precisely control the stretching of the fabric, adapting to different elastic fabrics and avoiding excessive stretching or rebound. The convenient clamping mechanism uses torsion springs and U-shaped inserts to achieve quick opening and closing and stable clamping without the need for continuous force, freeing the operator's hands and feet. The combination of the two not only reduces the labor required for operation but also improves the cutting accuracy and efficiency. Attached Figure Description

[0027] Example

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a fabric cutting and flattening device, including a cutting table 1 and a flattening mechanism above the cutting table 1, which takes the mounting block 2 as the basic carrier and provides stable support for the entire flattening action by means of its fixed connection with the upper end of the cutting table 1.

[0029] The movable groove 21 on the front of the mounting block 2 provides a guiding space for the movement of the threaded block 24. The servo motor 22 installed on one side of the mounting block 2 serves as a power source and drives the bidirectional lead screw 23 to rotate through the coupling. The bidirectional lead screw 23 uses its own thread structure to drive the two threaded blocks 24 that it cooperates with to move axially away from or close to each other within the movable groove 21.

[0030] This precise mechanical transmission method can accurately control the stretching degree of the fabric according to the needs of different elastic fabrics. For cotton and linen fabrics with poor elasticity, it can stretch them slowly and gradually to avoid the fabric fibers breaking due to excessive force.

[0031] For knitted fabrics with good elasticity, stretching can be stopped in time after moderate stretching to prevent excessive rebound of the fabric from affecting the cutting size and effectively ensuring the quality of flattening.

[0032] The support block 25 connected to the front of the threaded block 24 has a first anti-slip pad 27 connected to its upper end, which increases the friction between the support block 24 and the fabric, effectively preventing the fabric from sliding during the stretching process and ensuring the stability of the stretching action.

[0033] The support groove 28 opened at the upper end of the cutting table 1, and the symmetrical support slider 29 internally connected, are fixedly connected to the lower end of the support block 25, forming a stable sliding guide structure. When the threaded block 24 drives the support block 25 to move, the support slider 29 slides along the support groove 28, ensuring the straightness and stability of the support block 25 during movement, making the fabric stretch more even and improving the flattening accuracy.

[0034] The convenient clamping mechanism above the cutting table 1 forms the basic framework for clamping action through the fixed connection between the support 3 and the upper end of the support block 25.

[0035] The rotating rods 31 connected to the inner walls of both sides of the support 3 via bearings provide a fulcrum for the rotation of the rotating clamp 32. The symmetrical torsion springs 34 connected to both sides of the rotating clamp 32 are fixed at one end to the inner wall of the support 3. When the rotating clamp 32 is flipped open by an external force, the torsion springs 34 deform and store elastic potential energy.

[0036] After the external force disappears, the torsion spring 34 releases its elastic potential energy, causing the rotating clamp 32 to automatically flip and reset, realizing a quick opening and closing action, which makes it convenient for operators to place and take out the fabric. The limiting rods 33 connected to the inner walls on both sides of the support 3 can limit the flipping angle of the rotating clamp 32, generally limiting it to a range of 60 degrees, to avoid the rotating clamp 32 flipping too much, which would make it difficult to close and clamp later, thus improving the convenience of operation.

[0037] The second anti-slip pad 35 connected to the lower end of the rotating clamping block 32 increases the friction between the clamping block and the fabric, which can more firmly fix the fabric when clamping it, prevent the fabric from slipping during the flattening and cutting process, and ensure cutting accuracy.

[0038] The rotating clamp 32 has an internal mounting cavity 36 and an internally sliding block 37. One end of the return spring 38 connected to the back is fixed to the inner wall of the mounting cavity, and one end of the U-shaped plug 39 connected to the front passes through the rotating clamp 32.

[0039] When the rotating clamping block 32 needs to be opened, the operator pulls the U-shaped insert 39, causing the sliding block 37 to slide along the mounting cavity 36, stretching the return spring 38, so that the U-shaped insert 39 disengages from the slot 26 of the support block 25; after clamping the fabric, the U-shaped insert 39 is released, the return spring 38 releases its elastic potential energy, pushes the sliding block 37 forward, so that the U-shaped insert 39 is inserted into the slot 26 of the support block 25, thereby achieving stable positioning of the rotating clamping block 32 and completing the rapid and stable clamping of the fabric.

[0040] Compared to traditional manual clamping methods, this mechanism improves clamping efficiency and significantly enhances clamping stability, effectively freeing up the operator's hands and allowing them to focus on fabric flattening and cutting operations.

[0041] It should be noted that the electrical components mentioned above are all existing mature technologies. Appropriate models and power can be selected based on the technical knowledge of those skilled in the art, and they are controlled by PLC controllers, which are existing mature technologies. Therefore, they will not be described in detail again.

[0042] The working process of this utility model:

[0043] Step 1: The operator pulls the U-shaped insert 39, the sliding block 37 slides along the mounting cavity 36 and stretches the return spring 38, so that one end of the U-shaped insert 39 disengages from the slot 26 of the support block 25. At this time, the torsion spring 34 in the support 3 releases torque, causing the rotating clamp 32 to flip open around the rotating rod 31. The limiting rod 33 limits the flipping angle to prevent the angle from being too large and difficult to close. Align the two ends of the fabric to be cut and place them on the first anti-slip pads 27 of the support blocks 25 on both sides. Pull the U-shaped insert 39 again, keeping the return spring 38 in a stretched state, and press down on the rotating clamp 32 to flip it around the rotating rod 31 to a horizontal position. Use the second anti-slip pad 35 to adhere to the surface of the fabric, and slowly release the U-shaped insert 39. The elastic force of the return spring 38 pushes the sliding block 37 forward, causing the U-shaped insert 39 to insert into the slot 26 of the support block 25, completing the stable clamping of the two ends of the fabric without continuous force, freeing the operator's hands.

[0044] Step two: Start the servo motor 22 of the flattening mechanism. The output shaft drives the bidirectional lead screw 23 to rotate. Because the bidirectional lead screw 23 is threadedly engaged with the threaded block 24, and the threaded block 24 is limited by the moving groove 21, the two threaded blocks 24 move away from each other along the axial direction of the bidirectional lead screw 23. The threaded blocks 24 drive the two ends of the clamped fabric to be stretched synchronously through the support block 25 and the support 3, so as to achieve flattening. The operator can stop the servo motor 22 at any time by observing the flatness of the fabric, such as visually observing the unfolding of wrinkles and touching the tension uniformity, so as to accurately control the degree of flattening. It is suitable for different elastic fabrics such as cotton, linen, and knitted fabrics: for fabrics with poor elasticity, stop after a small stretch to avoid fiber breakage; for fabrics with good elasticity, stop after moderate stretching to prevent excessive rebound from affecting the size.

[0045] Step 3: After flattening, the operator uses a cutting tool to work along the cutting line. After completing the cutting, the first step is repeated. Pull the U-shaped insert 39 to disengage from the slot 26, open the rotating clamp 32, take out the finished product and leftover material, clean the cutting table 1, place the new fabric again, and clamp, flatten, and cut according to the process to achieve continuous operation and greatly improve the accuracy and efficiency of garment processing.
