Description

Technical Field

[0001] This invention relates to the field of automated garment processing technology, and in particular to an integrated device for automatic fabric spreading and automatic cutting of garments. Background Technology

[0002] In the field of automated garment processing, integrated automatic fabric spreading and automatic cutting equipment is the core equipment for realizing continuous production of fabric spreading, conveying and cutting. By integrating a reciprocating fabric spreading unit and a fixed cutting bed unit, it replaces manual fabric spreading and cutting operations, effectively improving the processing efficiency and cutting consistency of garment fabrics. It has been widely used in mass garment production workshops, home textile processing enterprises and other scenarios. In the actual production process, the fabric spreading unit needs to unfold the rolled fabric and continuously convey it to the cutting bed unit. The fabric condition at the junction of the two directly determines the subsequent cutting accuracy and fabric utilization rate. The tensioning and flattening structure design of this junction has been a long-standing technical pain point in the industry.

[0003] In existing integrated equipment, the fabric connection section generally lacks an adaptive mechanical tensioning structure, with most relying on pneumatic or electrically driven rollers to flatten and initially tension the fabric. From the perspective of actual workshop use, this design has significant drawbacks: Firstly, garment production workshops are typically accompanied by fabric fiber dust and accumulated thread debris. The cylinder piston rods and solenoid valves of pneumatic rollers are easily clogged by dust, leading to roller lifting and lowering jams and unstable pressure output. The motor drive module and pressure sensors of electrically controlled rollers are prone to short circuits and signal drift in dusty environments, resulting in frequent failures. Furthermore, each repair requires disassembly, cleaning, and sensor calibration, leading to long maintenance cycles and directly impacting continuous production line operation. According to industry statistics, the monthly failure rate of such electrical and pneumatic components can reach 15%-25%, and the annual maintenance cost is more than 30% higher than that of purely mechanical structures. Secondly... The types of fabrics involved in garment production vary greatly. Thin fabrics (such as silk and chiffon) are highly sensitive to tension. The pressure adjustment of existing pneumatic / electrically controlled pressure rollers relies on program settings or air pressure valve control. The adjustment accuracy is affected by voltage fluctuations and unstable air pressure. Excessive pressure can easily cause the fabric edges to stretch and deform, or even tear. Medium and heavy fabrics (such as cotton and polyester) require stable clamping tension to avoid slippage during conveying. However, most existing pressure rollers have a single fixed pressure output and cannot be adjusted adaptively according to the fabric thickness. Insufficient pressure from the pressure rollers can easily lead to the fabric becoming loose and wrinkled. Heavy fabrics (such as denim and corduroy) are hard. The upper limit of the pressure output of pneumatic pressure rollers is limited, making it difficult to achieve effective clamping. The motor load capacity of electrically controlled pressure rollers is insufficient, which can easily cause the pressure rollers to jam. At the same time, hard contact pressing will leave obvious indentations on the surface of heavy fabrics, affecting the flatness of the fabric in subsequent sewing processes. Summary of the Invention

[0035] Reference Figures 1-11This invention proposes an integrated automatic fabric spreading and automatic cutting machine for garments, including a cutting table 1. A mounting frame 2 is installed on the cutting table 1, and a unwinding roller 3 and a fabric unwinding and cutting mechanism 4 are mounted on the mounting frame 2. The fabric roll is fitted onto the unwinding roller 3. The fabric unwinding and cutting mechanism 4 is used to cut the fabric; this is prior art and will not be described in detail. A portal frame 5 is also installed on the cutting table 1. A support roller 6 and an auxiliary pressure roller 7 are rotatably mounted on the portal frame 5, arranged parallel to each other. An adjustable pressing mechanism is installed on the portal frame 5. This adjustable pressing mechanism is used to adjust the force exerted by the auxiliary pressure roller 7 against the support roller 6. The force exerted by the auxiliary pressure roller 7 against the support roller 6 is adjusted according to the thickness and material of the fabric. To ensure the fabric tension and avoid the effects of excessive or insufficient tension (for example, selecting the tension level according to the fabric type: thin fabrics (silk, chiffon): adjust the spring compression to level 1 using the adjustable clamping mechanism to reduce tension and prevent fabric tearing; medium-thick fabrics (cotton, polyester): adjust to level 2 to ensure stable tension and prevent slippage and wrinkling; thick fabrics (denim, corduroy): adjust to level 3 to increase spring compression and achieve effective clamping), a fabric pulling mechanism is slidably installed on the cutting table 1. The fabric pulling mechanism is used to pull the fabric roll on the unwinding roller 3 to lay it flat on the cutting table 1. In actual operation, the gantry frame 5 is located between the fabric unwinding and cutting mechanism 4 and the fabric pulling mechanism. The rotation of the unwinding roller 3 releases the fabric and clamps it with the fabric pulling mechanism. The fabric is pulled at one end, allowing it to lie flat on the cutting table 1. During the fabric pulling process, the adjustable pressing mechanism adjusts the force applied to the fabric by the auxiliary pressure roller 7, ensuring the tension of the fabric when it is stretched out. This eliminates the fabric's own curling stress and wrinkles, ensures stable fabric transport without slippage or deviation, counteracts fabric elastic shrinkage, ensures stable cut piece dimensions, reduces fabric pulling damage, improves fabric utilization, and enhances cutting quality and cut smoothness. The cutting table 1 is equipped with a synchronous transmission mechanism. When the fabric pulling mechanism slides, the synchronous transmission mechanism converts the sliding motion of the fabric pulling mechanism into the rotational motion of the support roller 6. In actual use, the synchronous transmission mechanism ensures that the rotational speed of the support roller 6 follows the fabric pulling motion. The mechanism's movement speed changes synchronously, thereby eliminating the speed difference between the fabric pulling and tensioning in real time. This avoids sudden changes in fabric tension (the fabric pulling mechanism's speed continuously changes during different stages such as start-up, constant speed operation, reversal, and deceleration; the real-time matching speed of the support rollers 6 prevents the fabric from being pulled too tight or too loose due to asynchronous speeds, ensuring stable fabric tension throughout the process). It also prevents fabric wrinkling, deviation, and tearing, and is suitable for thin and elastic fabrics (the speed-following changes keep the fabric in a gentle and uniform tension state, preventing wrinkling and lateral deviation due to roller speed lag or lead, and preventing tearing and deformation of thin or elastic fabrics due to sudden speed changes, significantly improving the smoothness of fabric conveying).

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustable clamping mechanism includes a lifting frame 8, an adjusting sleeve 9, a clamping rod 10, a clamping spring 11, and an adjusting assembly. The lifting frame 8 is vertically slidably mounted on the portal frame 5. The lifting frame 8 is also portal-shaped. Both ends of the auxiliary pressure roller 7 are rotatably mounted on the lifting frame 8 via a first rotating shaft. The adjusting sleeve 9 is mounted on the portal frame 5. The bottom end of the adjusting sleeve 9 has a lifting hole that slides with the clamping rod 10. The top end of the clamping rod 10 is slidably mounted in the lifting hole, and the bottom end of the clamping rod 10 is connected to the lifting frame 8. The clamping spring 11 is located in the lifting hole. The two ends of the clamping spring 11 abut against the top of the clamping rod 10 and the top inner wall of the lifting hole, respectively. The adjustment component is used to adjust the initial compression degree of the clamping spring 11. In actual use, the operator adjusts the initial compression degree of the clamping spring 11 according to the type of fabric to ensure the rebound force of the clamping spring 11. Thus, the clamping spring 11 drives the clamping rod 10, the lifting frame 8 and the auxiliary pressure roller 7 to descend synchronously, so that the auxiliary pressure roller 7 presses against the fabric, thereby controlling the tension of the fabric when it is laid out. Its structure is simple and convenient.

[0037] like Figure 3 As shown, the adjustment assembly includes an adjustment stud 12 and a clamping block 13. The bottom end of the adjustment stud 12 is threaded through the portal frame 5 and the adjustment sleeve 9 and extends into the lifting hole. The position of the adjustment stud 12 can be fixed by a positioning assembly, such as a locking nut or a buckle, to ensure the stability of the adjustment stud 12. The clamping block 13 is connected to the bottom end of the adjustment stud 12 and can slide in the lifting hole. The clamping block 13 abuts against the top of the clamping spring 11. In actual use, by rotating the adjustment stud 12, the clamping block 13 is driven to move in the lifting hole, thereby compressing the initial length of the clamping spring 11. The rebound force of the clamping spring 11 then acts on the end of the clamping rod 10, thereby adjusting the force of the auxiliary pressure roller 7 against the fabric.

[0038] like Figure 5As shown, the synchronous transmission mechanism includes a first gear 14, a first chain 15, a drive gear 16, and a traction assembly. There are four first gears 14, all of which are rotatably mounted inside the portal frame 5. The first chain 15 is wound around the four first gears 14 and meshes with them. The drive gear 16 is mounted on the second rotating shaft at the end of the support roller 6 and meshes with the first chain 15. The traction assembly is used to convert the sliding action of the fabric pulling mechanism into the meshing of one of the first gears 14. In actual use, during the movement of the fabric pulling mechanism, the traction assembly drives one of the first gears 14 to rotate. The rotation of the first gear 14 drives the first chain 15 to run, and the moving first chain 15 drives the drive gear 16 to rotate. The drive gear 16 drives the second rotating shaft and the support roller 6 to rotate synchronously, so that the rotation of the support roller 6 can change with the speed of the fabric pulling mechanism.

[0039] like Figure 7 As shown, the traction assembly includes a second gear 17, a second chain 18, and a linkage. There are two second gears 17, both of which are rotatably mounted inside the cutting table 1. The second chain 18 is fitted onto the two second gears 17, and the second gears 17 and the second chain 18 mesh to ensure the normal operation of the second chain 18. The linkage is used to convert the sliding action of the second chain 18 into the rotational action of one of the first gears 14. In actual use, during the fabric pulling process, the fabric pulling mechanism pulls the second chain 18 to move, and then drives one of the first gears 14 to rotate through the linkage, thereby driving the support roller 6 to rotate synchronously.

[0040] like Figure 6 As shown, the linkage includes a drive gear 19 and a transmission shaft 20. The drive gear 19 is rotatably mounted inside the cutting table 1 and meshes with the second chain 18. One end of the transmission shaft 20 is connected to the drive gear 19, and the other end is connected to one of the first gears 14. In actual operation, the second chain 18 drives the drive gear 19 to rotate during its movement. The drive gear 19 drives one of the first gears 14 to rotate synchronously through the transmission shaft 20. The first gear 14 then drives the first chain 15 to move, and the first chain 15 then drives the support roller 6 to rotate. This allows the support roller 6 to change according to the speed of the fabric spreading mechanism. Its structure ensures stable transmission and guarantees the stability of the transmission.

[0041] like Figure 1 , Figure 7 and Figure 8As shown, the fabric pulling mechanism includes a fabric pulling frame 21 and fabric pulling clamps 22. The fabric pulling frame 21 is slidably mounted on the cutting table 1. There are multiple fabric pulling clamps 22, which are arranged linearly on the side of the fabric pulling frame 21 near the fabric feeding and cutting mechanism 4. An electric telescopic rod or a pneumatic rod is also provided between the fabric pulling clamps 22 and the fabric pulling frame 21, which can drive the fabric pulling clamps 22 to move closer to or away from the fabric pulling frame 21. A drive rod 23 is connected to the fabric pulling frame 21, and the cutting table 1 has a connection point with the drive rod. The linear groove with sliding fit 23 has one end of the drive rod 23 connected to one link of the second chain 18. In actual use, multiple fabric clamps 22 clamp the edge of the fabric, so that the edge of the fabric is pulled evenly, reducing the situation of the fabric being pulled and becoming skewed. During the sliding of the fabric frame 21, the drive rod 23 is driven to slide synchronously, and then the drive rod 23 drives the second chain 18 to move, thereby driving the support roller 6 to change with the moving speed of the fabric frame 21.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a separating mechanism is installed on the fabric pulling frame 21. The separating mechanism is used to separate the support roller 6 and the auxiliary pressure roller 7. When the support roller 6 and the auxiliary pressure roller 7 are separated, the fabric pulling clamp 22 passes through the gap between the support roller 6 and the auxiliary pressure roller 7 and clamps the fabric. In actual use, since the support roller 6 is located between the fabric feeding and cutting mechanism 4 and the fabric pulling mechanism, when cutting the fabric, the edge of the fabric end is located at the fabric feeding and cutting mechanism 4. When the fabric pulling clamp 22 clamps the edge of the fabric end, it needs to pass through the gap between the support roller 6 and the auxiliary pressure roller 7 to clamp the edge of the fabric end. This requires the separating mechanism to drive the support roller 6 and the auxiliary pressure roller 7 to separate. The fabric pulling clamp 22 passes through the gap between the support roller 6 and the auxiliary pressure roller 7 to clamp the edge of the fabric end, so that the fabric can pass between the support roller 6 and the auxiliary pressure roller 7 to adjust the tension of the fabric.

[0043] like Figure 2 , Figure 4 and Figure 8As shown, the separating mechanism includes top rods 29 and separating components; there are four separating components, which are respectively mounted on the first rotating shaft at both ends of the support roller 6 and the second rotating shaft at both ends of the auxiliary pressure roller 7. There are four top rods 29, which are set one-to-one with the four separating components. The top rods 29 can drive the separating components to increase the distance between the support roller 6 and the auxiliary pressure roller 7. In actual use, the fabric pulling frame 21 drives the top rods 29 to move synchronously. First, the top rods 29 are inserted into the portal frame 5 and the lifting frame 8. Then, the top rods 29 push the four separating components to move away from each other, causing the support roller 6 and the auxiliary pressure roller 7 to separate. Then, the electric push rod drives the fabric pulling clamp 22 to move through the gap between the support roller 6 and the auxiliary pressure roller 7 to clamp the edge of the fabric end, pulling the fabric through the gap between the support roller 6 and the auxiliary pressure roller 7, thereby ensuring the control of the tension of the fabric during the spreading process, thus ensuring the quality of the fabric and the cutting quality.

[0044] like Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 10 and Figure 11As shown, the separation assembly includes a trapezoidal slider 24, a reset sleeve 25, a reset rod 26, and a reset spring 27. Both the gantry frame 5 and the lifting frame 8 have movable guide grooves 28 that slide with the trapezoidal slider 24. The four trapezoidal sliders 24 are respectively mounted on the first rotating shaft at both ends of the support roller 6 and the second rotating shaft at both ends of the auxiliary pressure roller 7. One end of the reset sleeve 25 is fixedly connected to the trapezoidal slider 24, and the end of the reset sleeve 25 away from the trapezoidal slider 24 has a sliding engagement with the reset rod 26. The telescopic hole has a return rod 26 with one end away from the return sleeve 25 resting against the inner wall of the movable guide groove 28. The return spring 27 is located inside the telescopic hole, with both ends of the return spring 27 abutting against the end of the return rod 26 and the inner wall of the end of the telescopic hole, respectively (the force of the first chain 15 on the drive gear 16 cannot drive the trapezoidal slider 24 to slide within the movable guide groove 28). In actual use, the rebound action of the return spring 27 causes the end of the return rod 26 to abut against the inner wall of the movable guide groove 28. The wall causes the trapezoidal slider 24 to be stuck in the movable guide groove 28. At this time, the trapezoidal slider 24 cannot move up and down in the movable guide groove 28, ensuring the positional stability of the support roller 6 and the auxiliary pressure roller 7, and ensuring the clamping effect on the fabric. When the end of the top rod 29 abuts against the trapezoidal slider 24, the trapezoidal slider 24 first makes a horizontal linear movement until the inclined surface of the trapezoidal slider 24 contacts the inner wall of the inclined surface of the movable guide groove 28. Then, the trapezoidal slider 24 slides along the inclined surface of the movable guide groove 28, and the end of the reset rod 26 slides on the inner wall of the movable guide groove 28, so that the two trapezoidal sliders 24 on the same side move away from each other, and simultaneously drive the support roller 6 and the auxiliary pressure roller 7 to move away from each other and open, so that the fabric clamp 22 can pass through the gap between the support roller 6 and the auxiliary pressure roller 7 to clamp the end edge of the fabric. When the top rod 29 is withdrawn, under the rebound action of the reset spring 27, the trapezoidal slider 24 slides back to its original position, ensuring the auxiliary clamping effect of the support roller 6 and the auxiliary pressure roller 7 on the fabric.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
