Description

Technical Field

[0001] The utility model relates to the technical field of embroidery equipment, in particular to an intelligent embroidery machine with an anti-thread jamming structure. Background Art

[0002] Embroidery machine is a high-precision, high-efficiency sewing equipment, an electromechanical product that combines an electrical control system and a mechanical system. It is widely used in embroidery, clothing, home textiles, knitting, shoes and hats, water-soluble lace, curtains, handicrafts and other industries;

[0003] The embroidery quality and thread breakage rate of the embroidery machine are the key indicators for evaluating the quality of the machine. The embroidery quality determines the fine effect of the embroidery and the precision of the machine, and the thread breakage rate directly determines the production efficiency of the machine and the economic benefits of the factory.

[0004] It is found in actual use that the existing embroidery machines have the following shortcomings:

[0005] When taking up and reeling in the thread, the existing embroidery machine needs to quickly retract a large amount of upper thread and tighten the upper thread at the same time to complete the knotting of the bottom thread on the cloth surface and form stitches. However, due to frequent thread replacement, the equipment cannot be adjusted in time, resulting in irregular thread taking-up stroke of the thread drum and actual thread consumption, which in turn leads to irregular movement of the bottom thread, abnormal tension of the bottom thread, and thread breakage.

[0006] In addition, when the tension of the upper thread is high, the machine cannot sense the thread, causing the tension of the upper thread to increase until it breaks, resulting in a high thread breakage rate.

[0007] Therefore, the present application provides an intelligent embroidery machine with an anti-thread jamming structure to meet the needs. Utility Model Content

[0008] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose an intelligent embroidery machine with an anti-thread jamming structure.

[0009] The technical problem to be solved by the utility model is to provide an intelligent embroidery machine with an anti-thread jamming structure to solve the problems of the existing intelligent embroidery machines with an anti-thread jamming structure.

[0010] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0011] An intelligent embroidery machine with an anti-thread jamming structure comprises: a frame, a flat embroidery thread clamp seat, a flat embroidery needle rod box, a color changing box, a computer operating panel, a workbench table top, a woolen embroidery presser foot, a rotating shaft, a bobbin, a limit block, a base, a telescopic spring, a fixed frame and a pressure sensor. A flat embroidery thread clamp seat is installed at the upper end of the front side of the frame, a flat embroidery needle rod box is installed at the lower end of the flat embroidery thread clamp seat, a color changing box is installed at the right end of the front side of the frame, a computer operating panel is installed on the side of the color changing box located on the frame, a workbench table top is installed in the middle of the frame, a woolen embroidery presser foot is installed on the workbench table top, a rotating shaft is installed on the side of the woolen embroidery presser foot located on the workbench table top, a bobbin is installed at the outer end of the rotating shaft, a limit block is installed on the bobbin, a base is installed at the bottom of the limit block, a telescopic spring is installed on the side of the base, a fixed frame is installed inside the bobbin, and a pressure sensor is installed on the fixed frame.

[0012] Preferably, the wool embroidery presser foot and the thread reel are respectively located on the left and right sides of the lower end of the flat embroidery needle bar box.

[0013] Preferably, the winding drum passes through the workbench table top and extends to the upper and lower ends of the workbench table top, and the winding drum is movably connected to the workbench table top through a rotating shaft.

[0014] Preferably, both upper and lower ends of the winding drum are provided with a long strip of grooves, and the limit block is embedded in the groove of the winding drum, and the limit block is slidably connected to the winding drum.

[0015] Preferably, four groups of limit blocks are provided on the winding drum, and the four groups of limit blocks are distributed on the left and right sides of the groove body at the upper and lower ends of the winding drum.

[0016] Preferably, the limit block is arranged in a semicircular shape, the base at the bottom of the limit block is located on the inner side of the winding drum, and the telescopic spring is transversely installed between the bases of the two groups of limit blocks.

[0017] Preferably, the fixing frame is in an "L" shape, the fixing frame extends downward to the lower end of the telescopic spring, and the pressure sensor is located in the middle of the bases of the two groups.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] 1. The upper thread on the embroidery needle bar at the lower end of the flat embroidery needle bar box can be wound up by the bobbin, and the bobbin can be rotated on the workbench through the rotating shaft. When the thread take-up rod tightens the upper thread, the bobbin with the upper thread wound on it rotates, which is helpful to reduce the resistance of the upper thread knotting at the bottom of the workbench. The rotation of the bobbin can appropriately delay the movement of the upper thread and reduce the thread breakage rate of the machine;

[0020] 2. The surface thread wound on the winding drum can be limited to the outer ends of the two sets of limit blocks, and the limit blocks can be moved when the surface thread is continuously wound. The limit blocks compress the telescopic spring so that the limit blocks can flexibly contact the surface thread. When the surface thread is continuously wound on the winding drum, the tension of the surface thread is relatively high. The surface thread clamps the limit blocks so that the limit blocks continuously move toward the middle. When the limit blocks move to the pressure sensor and contact the pressure sensor, the pressure sensor responds to judge that the tension of the surface thread is relatively large at this time, and it is necessary to maintain a margin of thread, thereby effectively reducing the thread breakage rate of the machine.

The flat embroidery thread clamp seat 2 is installed at the upper end of the front of the frame 1, the flat embroidery needle bar box 3 is installed at the lower end of the flat embroidery thread clamp seat 2, and the color changing box 4 is installed at the right end of the front of the frame 1. A computer operating panel 5 is installed on the side of the color changing box 4 of the frame 1, a workbench plate 6 is installed in the middle of the frame 1, a wool embroidery presser foot 7 is installed on the workbench plate 6, a rotating shaft 8 is installed on the side of the wool embroidery presser foot 7 of the workbench plate 6, a winding drum 9 is installed on the outer end of the rotating shaft 8, a limiting block 10 is installed on the winding drum 9, a base 11 is installed at the bottom of the limiting block 10, a telescopic spring 12 is installed on the side of the base 11, a fixing frame 13 is installed inside the winding drum 9, and a pressure sensor 14 is installed on the fixing frame 13.

[0030] In this embodiment, the wool embroidery presser foot 7 and the bobbin 9 are respectively located on the left and right sides of the lower end of the flat embroidery needle bar box 3. When embroidery work is performed, the embroidery needle bar in the flat embroidery needle bar box 3 reciprocates up and down to guide the surface thread, penetrate into the fabric and pull it out to form stitches, and the stitches are produced by the movement of the rotary shuttle and the embroidery frame.

[0031] In this embodiment, the wire reel 9 passes through the workbench table 6 and extends to the upper and lower ends of the workbench table 6, and the wire reel 9 is movably connected to the workbench table 6 through the rotating shaft 8. The wire reel 9 can wind up the surface thread on the embroidery needle bar at the lower end of the flat embroidery needle bar box 3, and the wire reel 9 can rotate on the workbench table 6 through the rotating shaft 8.

[0032] In this embodiment, both upper and lower ends of the winding drum 9 are provided with a long strip-shaped groove, and the limit block 10 is embedded in the groove of the winding drum 9. The limit block 10 and the winding drum 9 are slidably connected. When the thread taking-up rod tightens the surface thread, the winding drum 9 wound with the surface thread rotates, which is beneficial to reducing the resistance of the surface thread knotting at the bottom end of the workbench table 6. By rotating the winding drum 9, the movement of the surface thread can be appropriately delayed, thereby reducing the thread breakage rate of the machine.

[0033] In this embodiment, four groups of limit blocks 10 are provided on the winding drum 9, and the four groups of limit blocks 10 are distributed on the left and right sides of the groove body at the upper and lower ends of the winding drum 9. The surface line wound on the winding drum 9 can be limited to the outer ends of the two groups of limit blocks 10, and the limit blocks 10 can be moved when the surface line is continuously wound. The limit blocks 10 compress the telescopic spring 12, so that the limit blocks 10 can flexibly contact the surface line.

[0034] In this embodiment, the limit block 10 is arranged in a semicircular shape, the base 11 at the bottom of the limit block 10 is located on the inner side of the winding drum 9, and the telescopic spring 12 is horizontally installed between the bases 11 of the two groups of limit blocks 10. The surface of the semicircular limit block 10 is relatively smooth, so that when contacting the surface line, the friction can be reduced to prevent the surface line from breaking due to friction.

[0035] In this embodiment, the fixing frame 13 is in an "L" shape, and the fixing frame 13 extends downward to the lower end of the telescopic spring 12, and the pressure sensor 14 is located in the middle of the two groups of bases 11. When the surface thread is continuously wound around the winding drum 9, the tension of the surface thread is relatively high at this time. The surface thread clamping limit block 10 causes the limit block 10 to continuously move toward the middle. When the limit block 10 moves to the pressure sensor 14 and contacts the pressure sensor 14, the pressure sensor 14 responds to judge that the surface thread tension is relatively large at this time, and it is necessary to maintain a margin of thread, thereby effectively reducing the thread breakage rate of the machine.
