Description

Technical Field

[0001] This application relates to the field of garment manufacturing equipment technology, and more particularly to an automated cutting device for men's T-shirts. Background Technology

[0002] Men's T-shirts are usually made from two separate pieces of molded fabric sewn together at the edges. The traditional way to obtain separate pieces of fabric is for workers to hold a template and cut along the edges of the template. This is not only inefficient, but also because of the elasticity of the fabric, the edges are not easy to align, resulting in poor consistency of the cut pieces of fabric and making quality control more difficult. Summary of the Invention

[0003] The purpose of this application is to provide an automated cutting device for men's T-shirts that is more efficient and has better consistency.

[0004] To achieve the above objectives, this application provides an automated cutting device for men's T-shirts: including a cutting table and a feeding mechanism and a recycling mechanism cooperating with the cutting table. The feeding mechanism is adapted to supply fabric to the cutting table. The remaining scrap fabric after passing through the cutting table is rolled up by the recycling mechanism. The recycling mechanism and the feeding mechanism jointly tension the fabric. The cutting table includes a base, a support platform is fixedly connected to the upper surface of the base, a lifting plate is connected to the upper surface of the base via a first cylinder, a constraint plate is fixedly connected to the lower surface of the lifting plate via a traction rod, and a cutting blade is connected to the upper surface of the constraint plate via a second cylinder. The cutting blade includes a cutting blade, the inner wall of which is fitted with the outer side of the support platform to form a sliding pair, and is also adapted to fit with the outer side of the support platform to form a sliding pair. The fabric is adapted to pass between the support platform and the constraint plate. A single downward pressing action of the cutting blade can quickly and accurately cut out the shaped fabric.

[0005] As a preferred embodiment, a limiting plate is fixedly connected to the top of the cutting blade, which is suitable for fixed connection with the telescopic rod of the second cylinder. The limiting plate has a guide hole, which is suitable for cooperating with the traction rod to form a sliding pair for applying shear stress to the fabric.

[0006] As a preferred embodiment, the upper surface of the limiting plate is provided with convection holes that connect to the inside of the die, thereby reducing the air pressure resistance of the die moving relative to the constraint plate.

[0007] As a preferred embodiment, the main body of the constraint plate is a press plate, and the upper surface of the press plate is provided with a configuration groove. The cylinder of the second cylinder is fixedly connected in the configuration groove, making the structure of the entire device more compact.

[0008] As a preferred embodiment, the projections of the support, pressing plate, and cutting blade onto the fabric body are all consistent with the shape of the men's T-shirt to be made when it is laid flat, thus achieving high cutting accuracy.

[0009] As a preferred embodiment, a friction pad is fixedly connected to the bottom surface of the pressing plate. The shape and size of the friction pad are the same as those of the bottom surface of the pressing plate, which reduces the movement of the fabric near the cutting surface and further improves the cutting accuracy.

[0010] As a preferred embodiment, the feeding mechanism includes a pair of first shafts, with a feeding cylinder rotatably connected between the two first shafts, and a first drive is provided outside the first shafts to drive the feeding cylinder to rotate; the recycling mechanism includes a pair of second shafts, with a receiving cylinder rotatably connected between the two second shafts, and a second drive is provided outside the second shafts to drive the receiving cylinder to rotate, so as to maintain the consistency of fabric loading and unloading, as well as the flatness of the fabric itself.

[0011] As a preferred embodiment, the feeding cylinder has coaxial first retaining rings at both ends, with the complete fabric body located between the two first retaining rings; the receiving cylinder has coaxial second retaining rings at both ends, with the cut fabric body located between the two second retaining rings, thereby reducing radial movement of the fabric body during the receiving and receiving process.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a support platform, pressing plate and cutting blade with the same shape as the men's T-shirt when it is laid flat, a single action of the cylinder applies strong shear stress to the fabric, and the independent fabric is cut out quickly and accurately, which improves the cutting efficiency and ensures the shape consistency of the independent fabric.

[0014] (2) By designing a synchronous feeding mechanism and a recycling mechanism to tension the fabric, automatic loading and unloading can be achieved, further saving manpower and making the work more efficient and safer. Attached Figure Description

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8 The automated cutting device for men's T-shirts shown includes a cutting table 4 and a feeding mechanism 1 and a recycling mechanism 2 that cooperate with the cutting table 4. The feeding mechanism 1 includes a pair of fixedly arranged first shafts 101, and a feeding cylinder 102 is rotatably connected between the two first shafts 101. Fabric 3 is wound around the feeding cylinder 102. A first drive 104 is arranged outside the first shafts 101. The first drive 104 includes a cooperating servo motor and a reducer. The output end of the reducer is also the output end of the first drive 104, which is used to drive the feeding cylinder 102 to rotate. The recycling mechanism 2 also includes a pair of fixedly mounted second shafts 201, with a take-up cylinder 202 rotatably connected between the two second shafts 201 for taking up the fabric body 3 after cutting. A second drive 204 is provided outside the second shafts 201. The second drive 204 also includes a servo motor and a reducer that cooperate with each other. The output end of the reducer is the output end of the second drive 204, which is used to drive the take-up cylinder 202 to rotate. The feeding mechanism 1 is used to provide the fabric body 3 to the cutting table 4. The fabric body 3 remaining after cutting the table 4 is taken up by the recycling mechanism 2.

[0029] Furthermore, the recycling mechanism 2 and the feeding mechanism 1 together tension the fabric body 3, keeping the fabric body 3 in a straight state. The two ends of the feeding cylinder 102 have coaxial first retaining rings 103. The complete fabric body 3 is located between the two first retaining rings 103 and is constrained by the first retaining rings 103 to avoid contact and friction with the first shaft frame 101. The two ends of the receiving cylinder 202 have coaxial second retaining rings 203. The cut fabric body 3 is located between the two second retaining rings 203 and is constrained by the second retaining rings 203 to avoid contact and friction with the second shaft frame 201.

[0030] The cutting table 4 includes a fixed base 401. A support platform 402 is fixedly connected to the upper surface of the base 401. A lifting plate 404 is connected to the upper surface of the base 401 via a first cylinder 403. The lower end of the cylinder of the first cylinder 403 is fixedly connected to the base 401, and the upper end of the telescopic rod is fixedly connected to the lifting plate 404. In this embodiment, four first cylinders 403 are provided. The support platform 402 is located within a rectangular frame formed by the four first cylinders 403. A constraint plate 460 is fixedly connected to the lower surface of the lifting plate 404 via a traction rod 405 to provide constraint pressure to the fabric 3. A cutting blade 470 is connected to the upper surface of the constraint plate 460 via a second cylinder 408. It is an important component for cutting. The main body of the constraint plate 460 is a pressure plate. The upper surface of the laminating plate 461 is provided with a configuration groove 463, and the cylinder of the second cylinder 408 is fixedly connected in the configuration groove 463. The forming blade 470 includes a cutting blade 472, the cross section of the cutting blade 472 on the horizontal plane is continuous from end to end, and the top of the cutting blade 472 is fixedly connected to a limiting plate 471 for fixed connection with the telescopic rod of the second cylinder 408. The limiting plate 471 is provided with a guide hole 474, which cooperates with the traction rod 405 to form a sliding pair, which can improve the stability of the forming blade 470 when moving relative to the constraint plate 460. The upper surface of the limiting plate 471 is provided with a convection hole 473 that communicates with the inside of the forming blade 470 to ensure the internal and external air pressure balance of the space formed between the limiting plate 471 and the laminating plate 461.

[0031] The projections of the support plate 402, pressing plate 461, and cutting blade 472 onto the fabric body 3 all correspond to the shape of the men's T-shirt to be made when it is laid flat. The inner wall of the cutting blade 472 forms a sliding joint with the outer side of the support plate 402. When the sharp lower edge of the cutting blade 472 moves downward past the plane containing the top surface of the support plate 402, a portion can be cut off from the fabric body 3. This portion is the front or back of the men's T-shirt to be made. The fabric body 3, which is a whole piece of molded fabric on the back, needs to pass between the support plate 402 and the constraint plate 460. A rubber friction pad 462 is fixedly connected to the bottom surface of the pressing plate 461 to increase the contact friction between the pressing plate 461 and the fabric body 3, so as to ensure that the position of the fabric body 3 on the support plate 402 is stable during cutting. Under normal circumstances, the shape and size of the friction pad 462 are the same as the bottom surface of the pressing plate 461, which can reduce the material movement near the cutting surface and help maintain the consistency of cutting.

[0032] Working principle: During operation, the first drive 104 and the second drive 204 are activated, driving the feeding cylinder 102 and the receiving cylinder 202 to rotate synchronously, maintaining the tension of the fabric body 3. This allows the complete portion of the fabric body 3 to slide between the support table 402 and the friction pad 462 and stop. Then, the first cylinder 403 retracts, causing the pressing plate 461 to descend. The friction pad 462 presses the complete portion of the fabric body 3 firmly onto the support table 402. Then, the second cylinder 408 actuates, driving the cutting blade 470 to descend until the sharp edge of the cutting blade 472 contacts the fabric body 3 and crosses the horizontal plane of the support table 402. Under the action of strong shearing stress, the fabric body 3 is cut into the shape of a men's T-shirt. Then, the second cylinder 408... 08 extends, causing the die 470 to rise and reset. The first cylinder 403 extends, causing the pressing plate 461 to rise and reset. The friction pad 462 releases the constraint on the fabric 3. The first drive 104 and the second drive 204 start again, driving the straight fabric body to move towards the receiving cylinder 202. The continuous fabric body 3 will carry away the cut-off part on the support table 402. When half of the cut-off part leaves the upper surface of the support table 402, the cut-off part will slide down from between the base 401 and the second shaft frame 201 under the action of gravity, falling into the collection basket below or onto the conveyor belt for the next processing step. Meanwhile, a complete part of the fabric body 3 slides back to the upper surface of the support table 402, and the next round of cutting work can be carried out.
