Description

Technical Field

[0001] The invention relates to the technical field of clothing cutting and positioning, in particular to a positioning presser foot device for clothing cutting. Background Art

[0002] During the clothing processing, in order to cut the fabric into the required size and shape, the fabric is generally pre-cut first, so that the clothing blank of the approximate size and shape can be obtained, and then the subsequent sewing process is carried out. In the cutting process, in order to avoid the fabric from shifting and to ensure the accuracy of the cutting size and the flatness of the cutting edge, the positioning presser foot is generally used to press and position the corners of the fabric, so that the fabric can be reliably positioned in the specified position, which is convenient for people to cut.

[0003] In the prior art, patent document CN218059650U proposes a positioning presser foot device for clothing cutting, which belongs to the field of clothing cutting technology. The utility model discloses a positioning presser foot device for clothing cutting, comprising a fixed presser foot and a movable presser foot. The fixed presser foot has a double-layer structure, with a presser foot connector welded to the center of the upper surface of the fixed presser foot. The upper end of the presser foot connector is provided with a perforation, and spring plates are provided on both sides of the presser foot connector. The spring plates are fixedly connected to the upper layer of the fixed presser foot via a connector, and the lower surface of the fixed presser foot is provided with a cutting edge. The utility model solves the problems of existing clothing cutting devices such as inconvenience in use, easy deviation from the cutting line, inaccurate positioning, and easy wrinkling of clothing. The positioning presser foot device for clothing cutting realizes double-knife cutting at a fixed distance, realizes control of the cutting margin, and improves the accuracy and quality of cutting.

[0004] However, in actual use, most positioning presser feet, including the above-mentioned utility model, have been found to have different actual needs of different customers. Therefore, in clothing cutting, in order to meet the needs of different customers, different sizes of fabrics are used for cutting. Traditional positioning presser feet generally do not have the ability to adjust, and it is difficult to press and position the corners of fabrics of different sizes. In addition, due to the softness of the fabric itself, some parts of the fabric are prone to wrinkles and folds when it is laid flat, which will affect the normal cutting work, not only causing an increase in the defective rate of the cut fabric, but also a corresponding increase in material costs.

[0005] Therefore, it is necessary to provide a kind of clothing cutting positioning presser foot device to solve the above-mentioned technical problems. Summary of the Invention

[0043] In this embodiment

[0044] When the cloth needs to be cut, the cloth is first laid on the horizontal table 2, and one side of the cloth is placed under the convex frame 6, and then the output shafts of the two telescopic cylinders 5 are extended to make the convex frame 6 descend, and finally one side of the cloth is pressed tightly, and then the two rodless cylinders 53 are started, and the sliders of the two rodless cylinders 53 bring the lifting plate 31 up, and as the lifting plate 31 rises, the cloth laid on the horizontal table 2 will be lifted up, so that the cloth rises to a certain height. At this time, the cloth on both sides of the lifting plate 31 has a certain triangular space between the horizontal table 2, and the cloth on both sides of the lifting plate 31 has a certain triangular space between the horizontal table 2. After that, the two motors 2 are started, and the output shafts of the two motors 2 drive the corresponding lead screws 2 36 to rotate. At this time, the two smoothing rods 38 move toward each other by utilizing the threaded fit between the lead screw 2 36 and the connecting piece 2 37. During the movement, the two smoothing rods 38 are inserted into the same triangular space until the ends of the two smoothing rods 38 that are close to each other touch each other. Then, the two rodless cylinders 2 53 are started, and the sliders on the two lower the lifting plate 31 and separate from the cloth. At this time, the two smoothing rods 38 are inserted under the cloth and still lift the cloth a little height.

[0045] Then, the two motors 1 are started in the forward direction, and the output shafts of the two motors 1 drive the corresponding screws 1 33 to rotate. As the screws 1 33 rotate, the connecting piece 1 34 threadedly connected thereto begins to move, thereby being able to move the two box bodies 2 35 longitudinally and horizontally, so that the two smoothing rods 38 begin to move under the cloth. In the process of their movement, since they slightly lift the cloth, they can straighten some wrinkles or folds of the cloth until they move out from the other side of the cloth. At this time, the cloth is effectively flattened. Then, the motor 2 is started again to retract the two smoothing rods 38 to their original state, and the motor 1 is started in the reverse direction to bring the box body 2 35 back to its original position.

[0046] Then, the rodless cylinder 1 30 is started, and the slider on it moves the telescopic cylinder 5 20 horizontally, thereby moving the two pressing plates 24. After the two pressing plates 24 move to the other side of the cloth that is not pressed by the convex frame 6, the output shaft of the telescopic cylinder 6 27 is started to extend according to the width of the cloth, and the linkage plate 2 28 moves the multiple positioning posts 2 29 up, thereby bringing the corresponding positioning posts 2 29 out of the positioning groove 2 26, and then the two connecting bars 2 23 are moved. At this time, the connecting bars 2 23 can be observed. At the position of the second scale 25, after the two second pressing pieces 24 are moved to positions roughly corresponding to the upper and lower corners of the two fabrics, the second connecting strip 23 is slightly adjusted so that the second positioning groove 26 on it corresponds to the nearest second positioning post 29. Then, the output shaft of the sixth telescopic cylinder 27 is activated to retract, bringing the corresponding second positioning post 29 into the second positioning groove 26, thereby restricting the second connecting strip 23. Then, the output shaft of the fifth telescopic cylinder 20 is activated to extend, and finally, the two second pressing pieces 24 press the two corners of the fabric tightly.

[0047] Then, according to the same operation as above, first start the output shaft of telescopic cylinder three 14 to extend, and bring the corresponding positioning column 16 out of the corresponding positioning groove 13, then move the two connecting strips 10, move the pressing plate 11 to the specified position, and then start the output shaft of telescopic cylinder three 14 to retract, and bring the corresponding positioning column 16 into the positioning groove 13, thereby restricting the connecting strip 10, and then start the output shaft of two telescopic cylinders 15 to retract, and bring the edge strip 19 away from the cloth, and then start the output shaft of two telescopic cylinders 4 17 to extend, and bring the edge strip 19 to intersect with the shuttle mouth, and then start the output shaft of telescopic cylinder two 7 to extend, so that the pressing plate 11 passes through the shuttle mouth and finally presses the other two corners of the cloth, thus completing the flattening, straightening and four-corner positioning of the cloth, and then the staff takes out the cutting tools for cutting.

[0048] Compared with the related art, the positioning presser foot device for garment cutting provided by the present invention has the following beneficial effects:

[0049] The present invention provides a pressure strip 19 and two smoothing rods 38, which can first press one side of the cloth through the pressure strip 19, and then straighten the wrinkled or folded cloth at one time through the two movable smoothing rods 38, and then press the four corners of the cloth through the pressing plate 11 and the pressing plate 2 24, thereby improving the positioning effect and facilitating people to perform cutting work. At the same time, the smoothing, straightening and positioning operations can also ensure the flatness of the cut during the cutting process, thereby reducing the defective rate. In addition, through the adjustment connection between the positioning groove 13 and the multiple positioning columns 16, and the adjustment connection between the positioning groove 2 26 and the multiple positioning columns 2 29, at the same time, with the assistance of the rodless cylinder 1 30, the two pressing plates 11 and the two pressing plates 2 24 can be adjusted in position according to the actual cloth size, so that cloths of different sizes can be positioned and cut, and the applicability is significantly improved.

[0050] Second embodiment:

[0051] Based on the positioning presser foot device for garment cutting provided by the first embodiment of the present application, the second embodiment of the present application provides another positioning presser foot device for garment cutting. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0052] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation plans.

[0053] Please refer to Figure 13-14 The positioning presser foot device for clothing cutting also includes a supporting plate 39, which is fixed to one side of the side frame plate 3 near the side frame plate 2 4, and a box body 3 40 is fixed to the bottom of the supporting plate 39, in which a screw 3 41 is rotatably installed, one end of the screw 3 41 extends to the outside of the box body 3 40 and is fixed with a rotating handle, which is convenient for people to rotate, and a connecting piece 3 42 is threadedly installed on the screw 3 41. In order to ensure that the connecting piece 3 42 can only move linearly horizontally, a limiting rod 3 is fixed in the box body 3 40, and the limiting rod 3 passes through the connecting piece 3 42 and is slidably connected thereto, and a mounting frame 43 is fixed to the bottom of the connecting piece 3 42, and a telescopic cylinder 7 44 is fixed on the top inner wall of the mounting frame 43, and a guide column 45 is fixed on its output shaft, and the bottom end of the guide column 45 extends to the bottom of the mounting frame 43 and is fixed with a pressure line 46, and the guide column 45 is slidably connected to the mounting frame 43.

[0054] In the above method, in order to ensure that the connecting piece three 42 can be adjusted to the specified position, two support plates are fixed at the bottom of the supporting plate 39, and the same scale three 47 is fixed on the side where the two support plates are close to each other. The scale three 47 is located below the box body three 40, and the scale three 47 passes through the connecting piece three 42 and is slidably connected to the connecting piece three 42. The screw three 41 passes through the corresponding support plate and is movably connected to the corresponding support plate.

[0055] In this embodiment

[0056] When people are cutting, in order to ensure that the initial cut position can be ensured at the specified position when people are cutting, they can first rotate the screw three 41 according to actual needs to drive it to rotate together. At this time, through the threaded cooperation between the screw three 41 and the connecting piece three 42, the mounting frame 43 can be moved horizontally, thereby changing the position of the pressing line 46. At the same time, observe the position of the connecting piece three 42 on the scale three 47. After it moves to the specified position, stop the rotation of the screw three 41, and then start the output shaft of the telescopic cylinder seven 44 to extend, and bring the pressing line 46 down to contact with the cloth. At this time, it serves as a reminder to the staff, proving that the part where the pressing line 46 contacts the cloth is the initial position of cutting, thereby ensuring the accuracy of cutting.
