Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, and more specifically, to a die-cutting device for a yarn feeder tension wheel. Background Technology

[0002] The yarn feeder is the core device of knitting machinery. It is mainly used to precisely control the length and tension of the yarn feed to ensure the stability of the quality of the knitted fabric. Its core structure consists of a yarn feeder wheel directly connected to a stepper motor. Due to the limitations of the manufacturing process, the yarn feeder wheel will have residual mold lines on its outer circumference. Therefore, it is necessary to remove the mold lines of the yarn feeder wheel by a turning device to ensure the product quality of the yarn feeder wheel.

[0003] Common yarn feeder tension wheel die-cutting devices can only remove the die-cutting line on the outer circle of the yarn feeder wheel. However, in actual processing, it requires manual operation. Since the workpiece is relatively small and the processing operation is highly repetitive, it leads to excessive labor costs. In addition, manual operation makes it impossible to guarantee product quality and significantly reduces the product qualification rate.

[0004] In summary, to improve production efficiency, reduce labor costs, and ensure product quality stability, it is necessary to address the problems of high dependence on manual operation, low efficiency, and poor consistency in processing quality, and to automate, achieve high precision, and high reliability in the mold parting line removal process.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5A yarn feeder tensioning wheel die-cutting device includes a worktable 1, a workpiece rack 11 mounted on the upper end of the worktable 1, a hydraulic pump 12 mounted on the upper end of the worktable 1, a lifting push plate 13 rotatably connected to the output end of the hydraulic pump 12, a high support frame 14 mounted on the upper end of the worktable 1, a first motor 15 mounted on the upper end of the high support frame 14, a rotating pressure plate 16 mounted on the output end of the first motor 15, an attachment frame 17 mounted on the upper end of the worktable 1, a cylinder 18 mounted on the upper end of the attachment frame 17, a positioning push plate 19 mounted on the output end of the cylinder 18, a moving mechanism provided on the worktable 1, a horizontal moving block 20 provided on the moving mechanism, a cutting tool 21 installed inside the horizontal moving block 20, and a feeding mechanism provided on the worktable 1 and the workpiece rack 11.

[0023] It should be noted that the lifting and positioning of the workpiece is achieved by the hydraulic pump 12 driving the lifting push plate 13, the first motor 15 drives the rotating pressure plate 16 to rotate the workpiece, the cylinder 18 pushes the positioning push plate 19 for lateral positioning, and the moving mechanism controls the turning tool 21 to accurately process the mold parting line. The unloading mechanism realizes automatic unloading, which greatly improves the degree of automation of processing and solves the problem of low efficiency of manual operation.

[0024] It is worth noting that the lifting push plate 13 and the output end of the hydraulic pump 12 are rotatably connected, which can adaptively adjust the workpiece angle during the lifting process. The rotating pressure plate 16 is directly connected to the first motor 15 to ensure transmission accuracy. The positioning push plate 19 and the cylinder 18 work together to achieve rapid workpiece positioning and avoid the lifting push plate 13 from failing to accurately insert into the workpiece.

[0025] Refer to the instruction manual appendix Figures 3 to 5 The output end of the moving mechanism is connected to the horizontal moving block 20. The moving mechanism is used to control the horizontal movement and lifting movement of the turning tool 21. The moving mechanism includes a lifting component and a horizontal moving component. The output end of the lifting component is connected to the horizontal moving component. The lifting component is used to control the lifting movement of the horizontal moving component. The output end of the horizontal moving component is connected to the horizontal moving block 20. The horizontal moving component is used to control the horizontal movement of the horizontal moving block 20.

[0026] It should be noted that the moving mechanism adopts a separate design of lifting components and horizontal moving components, independently controlling the vertical and horizontal movement of the turning tool 21 to achieve complex trajectory machining and ensure complete coverage of the mold parting line turning.

[0027] Refer to the instruction manual appendix Figure 5 The lifting assembly includes a vertical frame 311 mounted on the upper end of the worktable 1, a second motor 312 mounted on the upper end of the vertical frame 311, a first lead screw 313 mounted on the output end of the second motor 312, and a lifting sliding block 314 mounted on the outside of the first lead screw 313. The second motor 312 is used to control the rotational movement of the first lead screw 313.

[0028] It should be noted that the lifting assembly drives the first lead screw 313 through the second motor 312, which in turn drives the lifting sliding block 314 to move vertically along the vertical frame 311. The structure is compact and has high rigidity, ensuring consistent turning depth.

[0029] Refer to the instruction manual appendix Figure 5 The horizontal moving assembly includes a horizontal frame 321 mounted on the surface of the lifting sliding block 314, a third motor 322 mounted on the surface of the horizontal frame 321, and a second lead screw 323 mounted on the output end of the third motor 322. The third motor 322 is used to control the rotational movement of the second lead screw 323, and the second lead screw 323 is threadedly connected to the horizontal moving block 20.

[0030] It should be noted that the horizontal moving component drives the second lead screw 323 through the third motor 322, which in turn moves the horizontal moving block 20 along the horizontal frame 321. The stroke is adjustable to accommodate the processing of workpieces of different sizes.

[0031] Refer to the instruction manual appendix Figure 3 The unloading end of the unloading mechanism is connected to the workpiece holder 11. The unloading mechanism is used to discharge the processed workpiece. The unloading mechanism includes an adjustment component and a guide component. The threaded end of the adjustment component is connected to the guide component. The adjustment component is used to adjust the position of the guide component. The guide component is used to limit the movement range of the workpiece and guide its unloading position.

[0032] It should be noted that the adjusting component of the feeding mechanism can finely adjust the position of the guide component to adapt to workpieces of different specifications. The guide component guides the workpieces out in an orderly manner through baffles and slides, realizing automatic sorting after processing.

[0033] It is worth noting that the adjustment and guiding components adopt a modular design, and can be adapted to various conveying scenarios by replacing the feed plate 422 with different inclination angles, making maintenance convenient.

[0034] Refer to the instruction manual appendix Figure 3 The adjustment assembly includes an adjustment frame 411 mounted on the upper end of the worktable 1, a threaded frame 412 mounted on the upper end of the adjustment frame 411, and a limit slider 413 threadedly connected to the inner side of the threaded frame 412.

[0035] It should be noted that the adjusting bracket 411 is fixed to the worktable plate 1, and the threaded bracket 412 is connected to the limiting slider 413 through a screw pair. The horizontal position of the guide component can be precisely adjusted by rotating the threaded rod on the threaded bracket 412.

[0036] Refer to the instruction manual appendix Figure 3 The guide assembly includes an L-shaped stop plate 421 mounted on the upper end of the limit slider 413 and a feed plate 422 mounted on the surface of the feed rack 11.

[0037] It should be noted that the L-shaped baffle plate 421 restricts the horizontal displacement range of the workpiece, and the unloading plate 422 is installed at an angle on the surface of the feeder 11, using gravity to make the workpiece slide into the collection area automatically without additional power.

[0038] Refer to the instruction manual appendix Figures 1 to 5 The hydraulic pump 12 is used to control the lifting and lowering movement of the lifting push plate 13, the first motor 15 is used to control the rotation movement of the rotating pressure plate 16, the lower end of the worktable plate 1 is equipped with a lower box 22, and the lower end of the lower box 22 is equipped with support feet 23 at the four corners.

[0039] It should be noted that the hydraulic pump 12 controls the lifting and lowering of the workpiece, and the first motor 15 drives the rotational machining. The two work together to achieve a fully automatic turning process. The lower housing 22 integrates the hydraulic and electrical control systems, and the support legs 23 improve the stability of the whole machine.

[0040] Working principle: After the workpiece is conveyed to the feeder 11 by the direct vibration turntable feeding device, the cylinder 18 pushes the positioning push plate 19 to position the workpiece laterally. Then, the hydraulic pump 12 drives the lifting push plate 13 to rise and clamp the workpiece. The lifting push plate 13 cooperates with the rotating pressure plate 16 to clamp the workpiece. The first motor 15 drives the rotating pressure plate 16 to rotate the workpiece at a uniform speed. The second motor 312 in the moving mechanism controls the vertical movement of the lifting sliding block 314 through the first lead screw 313. The third motor 322 drives the horizontal moving block 20 to feed horizontally through the second lead screw 323, so that the turning tool 21 cuts the outer circle parting line of the workpiece according to the set trajectory. After the machining is completed, the rotating pressure plate 16 and the lifting push plate 13 are reset, and the workpiece falls to the feeder 11. After being limited and guided by the L-shaped stop plate 421, it slides out and is collected along the unloading plate 422. The unloading mechanism adjusts the position of the limiting slider 413 through the adjusting frame 411 and the threaded frame 412 to adapt to workpieces of different sizes. The whole process is automated.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
