Description

Technical Field

[0001] This utility model relates to the field of overlock machine technology, and in particular to a feeding structure for an integrated overlock machine. Background Technology

[0002] In the textile and apparel industry and various fabric processing industries, with the rapid growth of consumer demand for product quality and personalization, manufacturers have placed extremely stringent requirements on the performance and efficiency of processing equipment. As the core equipment for fabric edge treatment, the integrated overlock machine's feeding structure design and functionality directly affect the smoothness of the entire production process, product quality, and production efficiency. In recent years, new textile materials have emerged continuously, and fabric materials have become increasingly diverse, from traditional cotton, linen, silk, and wool to various chemical fiber blends. At the same time, the thickness and width specifications of fabrics have also become increasingly varied. This makes it more urgent than ever for the overlock machine's feeding structure to accurately, efficiently, and stably adapt to the needs of fabrics with different characteristics.

[0003] However, traditional integrated overlock machines often use a single feeding parameter and mode. When processing fabrics of different materials, due to the lack of segmented and precise control of the speed during the feeding process, the fabric is often overstretched or damaged during the conveying process, which affects the original quality of the fabric and causes defects in the processed products, making it impossible to meet the market's requirements for high-quality products.

[0004] For example, when using a traditional feeding structure for overlocking chiffon fabric, the conveyor belt usually pushes the fabric at a relatively high speed. This causes the thin fabric to stretch and deform in the early stages of feeding due to excessive friction, resulting in the distortion of the originally uniform texture and wrinkles on the surface. Utility Model Content

[0005] This utility model discloses a feeding structure for an integrated overlock machine, aiming to solve the problem that the feeding structure of traditional integrated overlock machines often uses a single feeding parameter and mode. When processing fabrics of different materials, due to the lack of segmented and precise control of the speed during the feeding process, the fabric is often overstretched or damaged during the conveying process, which affects the original quality of the fabric and causes defects in the processed products, making it impossible to meet the market's requirements for high-quality products.

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

[0007] An integrated overlock machine's feeding structure includes a worktable, a control console mounted on the top outer wall of the worktable, multiple equally spaced guide rollers connected to one outer wall of the worktable, a connecting seat fixed to one outer wall of the worktable, a sewing needle mounted on the bottom outer wall of the connecting seat, and a presser foot connected to the outer wall of the sewing needle. The machine also includes: a conveying mechanism comprising a fixed base mounted on one outer wall of the worktable, three motors installed inside the fixed base, and a fixing groove matching the motors inside the fixed base; the output ends of the three motors are connected to conveyor belts with different conveying distances; and a protective mechanism located on the top outer wall of the fixed base.

[0008] In this solution, three motors are installed by creating a mounting slot inside the fixed base that matches the motor. The output ends of the three motors are all connected to a conveyor belt. When conveying fabric using a multi-segment conveyor belt, the conveyor belt speed can be adjusted at the beginning of the feeding process by adjusting the output power of the motors to prevent the fabric from being stretched or damaged. During the middle feeding process, the speed of the conveyor belt is adjusted appropriately according to the fabric's movement to ensure the fabric is flat. During the final feeding process, the speed of the conveyor belt is reduced again to ensure the fabric is delivered smoothly.

[0009] In a preferred embodiment, the protective mechanism includes protective sleeves installed on the top outer wall of the fixing base, the bottom outer walls of the three protective sleeves having slots, and the top outer wall of the fixing base having locking strips, the three locking strips matching the three slots.

[0010] When the protective cover is installed on the mounting base, the locking strip on the mounting base engages with the locking groove inside the protective cover, thus fixing the protective cover to the mounting base and preventing external dust, debris, etc. from entering the mounting base and avoiding damage to internal components such as the motor.

[0011] As described above, an integrated overlock machine's feeding structure includes a worktable, a control console mounted on the top outer wall of the worktable, multiple equally spaced guide rollers connected to one outer wall of the worktable, a connecting seat fixed to one outer wall of the worktable, a sewing needle mounted on the bottom outer wall of the connecting seat, and a presser foot connected to the outer wall of the sewing needle. The structure also includes: a conveying mechanism: the conveying mechanism includes a fixed seat mounted on one outer wall of the worktable, three motors installed inside the fixed seat, and a fixing groove matching the motors inside the fixed seat. The output ends of the three motors are all connected to conveyor belts, and the conveying distances of the three conveyor belts are different. A protective mechanism: the protective mechanism is located on the top outer wall of the fixed seat. The integrated overlock machine's feeding structure provided by this utility model has the technical effects of segmented and precise speed control during the feeding process, avoiding excessive stretching or damage to the fabric during conveying, preventing external dust and debris from entering the equipment, and facilitating disassembly.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The feeding structure of the integrated overlock machine disclosed in this utility model is mainly applied to the traditional integrated overlock machine feeding structure, which often adopts a single feeding parameter and mode. When processing fabrics of different materials, due to the lack of segmented and precise control of the speed during the feeding process, the fabric is often overstretched or damaged during the conveying process, which affects the original quality of the fabric and causes defects in the processed products, making it impossible to meet the market's requirements for high-quality products.

[0019] Reference Figure 1 , Figure 2 and Figure 3 An integrated overlock machine's feeding structure includes a workbench 1, a control console 3 mounted on the top outer wall of the workbench 1, multiple equally spaced guide rollers 2 connected to one side outer wall of the workbench 1, a connecting seat 4 fixed to one side outer wall of the workbench 1, a sewing needle 5 mounted on the bottom outer wall of the connecting seat 4, and a presser foot connected to the outer wall of the sewing needle 5. The machine also includes: a conveying mechanism: the conveying mechanism includes a fixed seat 6 mounted on one side outer wall of the workbench 1, three motors 8 installed inside the fixed seat 6, and a fixing groove matching the motors 8 opened inside the fixed seat 6. The output ends of the three motors 8 are all connected to conveyor belts 7, and the conveying distances of the three conveyor belts 7 are different; and a protective mechanism: the protective mechanism is located on the top outer wall of the fixed seat 6.

[0020] In this design, three motors 8 are installed by creating a mounting slot inside the fixed base 6 that matches the motor 8. The output ends of the three motors 8 are all connected to a conveyor belt 7. When conveying fabric, the multi-segment conveyor belt 7 can be used to slow down the speed of the conveyor belt 7 during the initial feeding stage by adjusting the output power of the motors 8 to prevent the fabric from being stretched or damaged. During the middle feeding stage, the speed of the conveyor belt 7 is adjusted appropriately according to the running condition of the fabric to ensure that the fabric is flat. During the final feeding stage, the speed of the conveyor belt 7 is reduced again to ensure that the fabric is delivered smoothly.

[0021] Among them, the outer wall of the three conveyor belts 7 near the connecting seat 4 is at the same height as the top outer wall of the fixed seat 6, so that the fabric can be smoothly transferred during the feeding process and will not be stuck or deviated due to the height difference.

[0022] Specifically, the three motors 8 are used to control the output speed of the three conveyor belts 7. When dealing with fabrics of different materials, thicknesses and feeding process requirements, the operator can set the parameters of the three motors 8 through the control panel 3.

[0023] Reference Figure 3 and Figure 4 In a preferred embodiment, the protective mechanism includes protective sleeves 9 installed on the top outer wall of the fixed base 6, the bottom outer walls of the three protective sleeves 9 are provided with slots 10, and the top outer wall of the fixed base 6 is fixed with clips 11, the three clips 11 and the three slots 10 are matched with each other.

[0024] In this solution, when the protective sleeve 9 is installed on the fixed base 6, the locking strip 11 on the fixed base 6 engages with the locking groove 10 inside the protective sleeve 9, thereby fixing the protective sleeve 9 and the fixed base 6 together, thus preventing external dust, debris and other objects from entering the fixed base 6 and avoiding damage to internal components such as the motor 8.

[0025] Both the clip 11 and the slot 10 are U-shaped structures. The tight fit between the clip 11 and the slot 10 effectively prevents external debris from entering the motor 8.

[0026] In particular, the protective cover 9 is made of plexiglass, which makes it easy for operators to observe the operating status of the motor 8.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, a position sensor is installed on the bottom outer wall of the connector 4, and two electric push rods are built inside the connector 4. The output end of one electric push rod is connected to a presser foot, and the output end of the other electric push rod is connected to a sewing needle 5.

[0028] The movement of the presser foot and sewing needle 5 is powered by two independent electric actuators.

[0029] Working Principle: During operation, the fabric is first placed on the upper surface of the front conveyor belt 7. Based on the fabric's characteristics, the operator can adjust the output power of the motor 8 via the control console 3. For thin and fragile fabrics, the output power of the motor 8 is reduced, causing the front conveyor belt 7 to operate at a slower speed. This minimizes the traction force on the fabric during the initial feeding stage, effectively preventing stretching or damage. As the fabric enters the middle conveyor belt 7, position sensors installed in the feeding structure monitor its movement in real time. These sensors feed the detected signals back to the control console 3, which adjusts the output power of the corresponding motor 8, thereby changing the speed of the middle conveyor belt 7. This ensures consistent speed across all parts of the fabric, keeping it flat. During the later feeding stages, the output power is reduced via the control console 3. The output power of motor 8 slows down the speed of conveyor belt 7, so that the fabric is conveyed out of the rear conveyor belt 7 in a slow and stable state, thereby avoiding the inertial impact caused by excessive speed and ensuring the accuracy and stability of feeding. Secondly, the top outer wall of the fixed base 6 is fixed with a locking strip 11 that matches the locking groove 10 inside the protective sleeve 9. Both the locking strip 11 and the locking groove 10 are U-shaped structures. When installing the protective sleeve 9, the protective sleeve 9 is placed on the top of the fixed base 6 so that the locking strip 11 is accurately embedded in the locking groove 10. At the same time, the protective sleeve 9 is made of plexiglass, which can effectively prevent external dust, debris and other objects from entering the interior of the fixed base 6, avoiding damage to key components such as the motor 8 inside. At the same time, the transparency of plexiglass allows operators to observe the operating status of motor 8 at any time. Once an abnormality is found in motor 8, the machine can be stopped in time for maintenance.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
