Description

Technical Field

[0001] The invention relates to the technical field of cloth processing, and more particularly to a lace cutting machine for lace cloth. Background Art

[0002] Clothing is one of the essential items for people, and clothing is mainly made of fabrics of various materials. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. With the improvement of people's living standards, various clothing fabrics have gradually entered people's lives. Among them, lace fabrics are widely used in women's underwear because of their light and transparent texture, elegant and mysterious artistic effects. When lace fabrics are used as clothing fabrics, in order to increase the beauty of clothing, it is necessary to use a fabric cutting machine to cut the lace fabrics, thereby increasing the overall beauty of clothing.

The lace cutting machine for fabric processing achieves the effect of changing the distance of the lace when the rotating shaft drives the triangular knife to rotate and cut the fabric on the placement table by setting a guide frame, a positioning rod, a slide rod, a squeeze rod and an adjustment ring, solving the problem that the distance of lace cutting by the current lace cutting machine is relatively single, and different machines need to be replaced when lace of different distances needs to be cut.

[0004] However, the above device still has some shortcomings in actual use.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Therefore, the operator first places the lace fabric between the two limit plates 15 on the cutting table body 11, and then turns on the first motor 13 to rotate. The rotation of the first motor 13 drives the first bidirectional screw rod 14 to rotate. The rotation of the first bidirectional screw rod 14 drives the two limit plates 15 to move toward each other until the two limit plates 15 contact the two sides of the lace fabric and limit the lace fabric. Then the operator passes the lace fabric under the two pressing rollers 18, and then rotates the adjusting screw 19 to drive the sliding block 17 to slide on the fixed frame 16. The sliding of the sliding block 17 drives the pressing roller 18 to move until the pressing roller 18 contacts and squeezes the lace fabric.

[0040] Therefore, the operator passes one end of the lace fabric through the pressing roller 18 and then wraps it around the surface of the collecting roller 23. Then the operator turns on the third motor 25 to rotate. The rotation of the third motor 25 drives the second bidirectional screw rod 26 to rotate. The rotation of the second bidirectional screw rod 26 drives the two sliding plates 27 to move toward each other until the two sliding plates 27 contact and limit the lace fabric. Then the operator turns on the second motor 22 to rotate to drive the lace fabric to move on the cutting table body 11 and automatically flatten it through the pressing roller 18.

[0041] See attached Figure 2-6The adjusting mechanism 3 includes a cutting frame 31, an electric push rod 32, a sliding limit groove 33, a slider 34, a mounting plate 35, a third sliding groove 36, a third bidirectional screw rod 37 and a fourth motor 38, wherein the cutting frame 31 is fixedly connected to the top of the cutting table body 11, the electric push rod 32 is fixedly connected to the top of the cutting frame 31 and the output end of the electric push rod 32 passes through the cutting frame 31, the sliding limit groove 33 is arranged on the two side surfaces of the cutting frame 31 and passes through the cutting frame 31, two sliders 34 are provided, and the two sliders 34 are slidably connected to the inside of the cutting frame 31 through the sliding limit groove 33, the mounting plate 35 is fixedly connected between the two sliders 34 and is fixedly connected to the output end of the electric push rod 32, the third sliding groove 36 is arranged on a side of the mounting plate 35 close to the cutting table body, the fourth motor 38 is fixedly connected to the mounting plate 35 and the output end of the fourth motor 38 passes through the mounting plate 35 and extends into the third sliding groove 36, and the third bidirectional screw rod is rotatably connected to the inside of the third sliding groove 36 and one end is fixedly connected to the output end of the fourth motor 38.

[0042] Refer to the attached Figure 5-7 , the cutting mechanism 4 is mirror-set in two groups, and the two groups of cutting mechanisms 4 include a sliding rod 41, a rotating rod 42, a mounting block 43, a connecting rod 44, a lace cutting knife 45, a plane pressure wheel 46, a limiting hole 47, a limiting rod 48, a first magnetic block 49, a handle 410 and a second magnetic block 411, wherein the sliding rod 41 is threadedly sleeved on the outside of the third bidirectional screw rod 37 and is located below the mounting plate 35, the rotating rod 42 is rotatably connected to the sliding rod 41 through a bearing, the mounting block 43 is fixedly connected to one end of the rotating rod 42, a plurality of connecting rods 44 are provided, and a plurality of connecting rods 44 are fixedly connected to the mounting block 43 and are evenly distributed around the mounting block 43, the plane pressure wheel 46 is rotatably connected to one of the connecting rods 44, and the lace cutting knife 45 is provided There are multiple lace cutting knives 45 which are rotatably connected to the remaining connecting rods 44 respectively, and the blade of each lace cutting knife 45 has a different flower shape. The limiting hole 47 is opened on the surface of the mounting block 43 close to the sliding rod 41. The limiting rod 48 passes through the sliding rod 41 and is slidably connected to the sliding rod 41. The first magnetic block 49 is fixedly connected to the limiting rod 48, and the second magnetic block 411 is fixedly connected to the side of the sliding rod 41 close to the first magnetic block 49. The handle 410 is fixedly connected to the side of the first magnetic block 49 away from the limiting rod 48. The second magnetic block 411 is fixedly connected to the outside of the sliding rod 41. The limiting rod 48 matches the size and position of the limiting hole 47, and the size and position of the first magnetic block 49 matches the second magnetic block 411.

[0043] Therefore, when the lace fabric is wound, the operator turns on the fourth motor 38 to rotate, and the rotation of the fourth motor 38 drives the third bidirectional screw rod 37 to rotate, thereby driving the two sliding rods 41 to move toward each other, the movement of the sliding rod 41 drives the rotating rod 42 and the mounting block 43 to move, the movement of the mounting block 43 drives the connecting rod 44 to move, and the movement of the connecting rod 44 drives the lace cutting knife 45 to move, until the lace cutting knife 45 moves to the cutting position of the lace fabric to be cut, and then the operator selects the lace cutting knife 45 according to the shape of the lace to be cut, and the operator first pulls the handle 410 to drive the first magnetic block 49 and the second magnetic block 411 to disengage from adsorption until the limit rod 48 is completely The limiting hole 47 is completely disengaged, and then the operator rotates the rotating rod 42 to drive the mounting block 43 to rotate, and the mounting block 43 rotates to drive the connecting rod 44 to rotate, and the mounting block 43 rotates to drive the lace cutting knife 45 and the flat pressing wheel 46 to rotate, so as to rotate the required lace cutting knife 45 to the bottom as needed, and then push the handle 410 to drive the first magnetic block 49 and the limiting rod 48 to move until the first magnetic block 49 and the second magnetic block 411 are adsorbed again. At this time, the limiting rod 48 is inserted into the limiting hole 47 to limit the rotating rod 42 and the mounting block 43 again. When only one side of the lace fabric needs to be cut, the operator only needs to adjust the flat pressing wheel 46 on the other side to the bottom and then fix it.

[0044] After the lace cutting knife 45 is selected, the operator turns on the electric push rod 32, and the electric push rod 32 drives the mounting plate 35 to move downward and drives the slider 34 to slide downward in the sliding limit groove 33. The movement of the mounting plate 35 drives the sliding rod 41 to move downward, and the movement of the sliding rod 41 drives the rotating rod 42 and the mounting block 43 to move downward. The movement of the mounting block 43 drives the connecting rod 44 and the lace cutting knife 45 to move downward until the lace cutting knife 45 cuts the lace fabric it contacts and contacts the cutting table body 11. At this time, as the lace fabric moves, the lace cutting knife 45 can be driven to rotate and continuously cut the lace fabric. The whole process realizes automatic cutting to avoid manual operation by the operator.

[0045] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
