Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a fabric cutting machine for garment processing. Background Technology

[0002] A fabric cutting machine is a mechanical device used to cut fabric. Fabric cutting machines are widely used in many fields such as garment manufacturing, home textiles, and automobile seat manufacturing. Especially in the garment processing field, canvas production and processing all require the use of cutting machines to cut fabric to different sizes.

[0003] An investigation revealed that a Chinese utility model patent discloses a fabric cutting machine (publication number: CN219490504U), comprising: a fixed block, with universal wheels fixedly installed at the four corners of the bottom surface of the fixed block, and a cutting pad fixedly installed on the top surface of the fixed block; and a cutting assembly, disposed on the top surface of the fixed block for cutting clothing fabric. The cutting assembly includes a limiting frame, which is fixedly installed on the top surface of the fixed block. A drive hole is provided on the top surface of the limiting frame, and an electric hydraulic rod is fixedly installed on the top surface of the limiting frame. A pressing block is disposed inside the limiting frame. One end of the telescopic rod of the electric hydraulic rod passes through the drive hole and is fixedly installed on the top surface of the pressing block. The electric hydraulic rod drives the pressing block to press down on the cutting pad. At this time, the two pressing plates press down on both sides of the fabric respectively, and then the cutting blades cut the fabric. The cutting speed is fast, increasing work efficiency. The limiting block is used to prevent the connecting rod from falling off the pressing block.

[0004] The aforementioned patent uses a pressing plate to press down on both sides of the fabric, and then the cutting scissors move downwards to complete the cutting. Although this cutting method presses and positions the fabric, it cannot assist in positioning the edges. Furthermore, the cutting scissors press down perpendicularly to the upper surface of the fabric, which increases the pressure area on the blade, affecting the cutting effect and requiring a high degree of sharpness from the blade. This makes cutting the fabric inconvenient and reduces the flexibility and accuracy of the cutting process.

[0005] Therefore, this utility model provides a fabric cutting machine for garment processing to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5 As shown, this utility model provides a fabric cutting machine for garment processing, including a worktable 1, a pressing assembly 2 above the worktable 1 for pressing and positioning the fabric; a positioning bracket 4, which includes a second bracket 41 fixedly connected to one end of the worktable 1, and a support shaft 42 rotatably connected between the two second brackets 41. An extrusion plate 43 is sleeved on the outer wall of the support shaft 42, and an adjusting frame 44 is rotatably connected to the outside of the extrusion plate 43. A limiting frame 45 is slidably sleeved on the other end of the adjusting frame 44 and fixedly connected to the outer wall of the worktable 1; and a cutting assembly 6, which is located inside the lifting end of the pressing assembly 2 and is used for cutting the fabric. The cutting assembly 6 includes a first motor 61 fixedly connected to the outer wall of the housing 23, and the first motor 61... A lead screw 62 is fixedly connected to the output end. The lead screw 62 is rotatably located inside the housing 23. A nut pair 63 is connected to the outside of the lead screw 62, and a guide seat 64 is fixedly connected to the outer wall of the nut pair 63. A cutter 65 is fixedly connected to the bottom of the guide seat 64. Through the cooperation of the positioning bracket 4 and the cutting assembly 6, in the initial cutting state, the curved blade of the cutter 65 corresponds to the positioning edge of the fabric. Then, while the pressing assembly 2 descends to press the fabric, the curved blade of the cutter 65 contacts the edge of the fabric, realizing the cutting of the fabric. Furthermore, driven by the first motor 61, the lead screw 62 is driven to rotate, thereby driving the cutter 65 to move through the guide seat 64 via the lateral displacement of the nut pair 63, thus realizing the cutting of the fabric. This effectively reduces the contact area between the cutter 65 and the fabric and improves its cutting sharpness.

[0029] Furthermore, the pressing assembly 2 includes a first bracket 21, a first cylinder 22 is fixedly connected to the upper surface of the first bracket 21, a housing 23 is connected to the lifting end of the first cylinder 22, positioning plates 24 are symmetrically distributed on the outer wall of the housing 23, a guide shaft 25 passes through the horizontal end of the positioning plate 24, a pressing plate 26 is fixedly connected to the bottom of the guide shaft 25, and a spring 27 is sleeved on the outside of the guide shaft 25. The housing 23 is lowered by starting the first cylinder 22. When the pressing plate 26 comes into contact with the upper surface of the fabric, the housing 23 continues to descend, the spring 27 contracts, and the pressing plate 26 provides a greater force to squeeze the fabric, thus completing the pressing and positioning of the fabric and preventing the fabric from shifting during cutting.

[0030] Furthermore, the spring 27 abuts against the positioning plate 24 and the pressing plate 26. The housing 23 is the lifting end of the pressing assembly 2. The pressing plate 26 is used to press and fix the fabric. The lower surface of the pressing plate 26 is provided with an anti-slip pad. The anti-slip pad is provided to avoid excessive compression of the fabric and prevent indentations, thus providing safety protection for the fabric.

[0031] Furthermore, a knife groove 3 is provided above the workbench 1, and two clamping plates 26 are respectively located on both sides of the knife groove 3. A guide roller 5 is also provided above the workbench 1, and the guide roller 5 is used for guiding and conveying the fabric. The main purpose of the guide roller 5 is to guide the fabric so that the fabric adheres to the upper surface of the workbench 1 for conveying.

[0032] Furthermore, one end of the support shaft 42 is stepped, and the extrusion plate 43 has a stepped structure. The small-diameter outer wall of the extrusion plate 43 is rotatably connected to the adjustment frame 44 via a bearing. The end of the adjustment frame 44 away from the extrusion plate 43 is slidably engaged between the limiting frame 45 and the outer wall of the worktable 1. The center of the limiting frame 45 has a guide groove, and the inside of the guide groove has a clamping bolt 46 threadedly connected to the adjustment frame 44. The extrusion plate 43 abuts against one end of the fabric roll, thus assisting in the positioning of the fabric during installation. This ensures that the end of the fabric away from the extrusion plate 43 is aligned with the arc-shaped blade of the cutter 65. The outer wall of the clamping bolt 46 is provided with a clamping ring that presses against the outer wall of the limiting frame 45. Thus, under the threaded connection of the clamping bolt 46, the clamping of the limiting frame 45 completes the auxiliary positioning of the adjustment frame 44, ensuring the stability of the extrusion plate 43 in limiting the fabric.

[0033] Furthermore, the blade 65 has an arc-shaped structure, and the bottom of the housing 23 is provided with a limiting groove that adapts to the sliding of the guide seat 64. The thickness of the blade 65 is less than the width of the groove 3, and the blade 65 is located at the center line of the groove 3. By setting the arc-shaped blade of the blade 65, the cutting of the fabric edge is achieved by the descent of its arc-shaped blade, thereby improving the sharpness of the fabric edge cutting.

[0034] Working principle: First, the fabric roll is installed and positioned so that it is placed outside the support shaft 42. By adjusting the position of the extrusion plate 43, the extrusion plate 43 extrudes and limits the fabric roll, so that the fabric is conveyed by being conveyed by the guide roller 5 and in contact with the surface of the worktable 1. After the fabric is pulled to a certain length, the first cylinder 22 descends, driving the housing 23 and other components to descend. First, the pressing plate 26 presses and contacts the fabric to complete the pressing and positioning of the fabric. Then, the curved blade of the cutter 65 contacts the edge of the fabric to achieve the cutting of the fabric. Further, by controlling the lateral displacement of the cutter 65, the cutting process of the fabric can be achieved.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
