Description

Technical Field

[0001] The invention relates to the technical field of leather production equipment, and in particular to an intelligent stitch management device for a leather sewing machine. Background Art

[0002] The traditional leather processing process is as follows (taking sewing as an example): the operator first cuts the whole roll of leather into pieces of suitable size, then clamps the cut pieces of leather on the fixture, and then assembles the fixture into the sewing machine. The sewing machine and the fixture cooperate to complete the sewing of the pieces of leather. The operator then removes the sewn pieces of leather and installs new pieces of leather to be sewn.

[0003] During the leather sewing process, the leather is pushed by hand to move. Manual pushing is unstable and can easily cause the seam line to shift, thus affecting the finished product. Manual pushing is also inconvenient to control the perforation distance of the leather. Therefore, an auxiliary mechanism is set up to promptly remind workers that the seam line is about to shift and ensure normal stitching. Summary of the invention

DETAILED DESCRIPTION

[0028] The embodiment of the present invention provides an intelligent stitch management device for a leather sewing machine, such as Figure 1-7 As shown, it is installed at the needle and thread sewing mechanism, including a rectangular base plate 1, a hole is opened in the center of the base plate 1, and the sewing mechanism of the sewing machine passes through the base plate 1. A bracket is welded on the top of the base plate 1, and the bracket is fixedly installed with the leather sewing machine. The front and rear ends of the base plate 1 are both opened with a through slot 11, and a frame 2 is welded on the top of the base plate 1 relative to the through slot 11.

[0029] A base 4 is placed inside the frame 1 2 , and a straight thick electric push rod 47 is pivotally connected to the top of the base 4 , and the top of the thick electric push rod 47 is fixedly installed with the top of the frame 1 2 .

[0030] The base 4 is in a concave shape, and a roller 41 is pivotally connected inside the base 4. A connecting strip 21 is welded to the side of the top of the frame 2. The connecting strip 21 has a fork vertically downward, and a magnet 22 is fixedly installed vertically downward on the fork. A magnet 2 43 is fixedly installed on the top of the base 4. The magnet 2 43 corresponds to the magnet 1 22 one by one. The roller 41 is used to contact the leather, and the magnet 2 43 and the magnet 1 22 attract each other.

[0031] Extension portions 15 are welded at the bottom of the substrate 1 and on both sides of the through slot 11 . Pressure sensing units 1 42 are symmetrically connected to the outer side of the base 4 . The roller 41 is pivotally connected between the two pressure sensing units 1 42 .

[0032] Working principle: When the leather moves in an outwardly biased direction, the leather drives the roller 41 to deflect slightly, causing the pressure sensing unit 42 to touch the extension portion 15, and the pressure sensing unit 42 generates an electrical signal and transmits it to the computer terminal.

[0033] Slide grooves are provided on both sides of the base 4, and one side of the pressure sensing unit 42 moves in the slide groove. A slider 44 is slidably matched in the slide groove, and the slider 44 is fixedly installed with one side of the pressure sensing unit 42. A spring 45 is welded on the top of the slider 44, and the upper end of the spring 45 is welded to the top of the inner wall of the slide groove.

[0034] A rotating shaft 23 driven by a motor is fixedly installed between the bifurcations of the connecting bar 21 . A steel wire 46 is welded to the shaft of the rotating shaft 23 . The lower end of the steel wire 46 passes through the base 4 and is welded to the slider 44 .

[0035] Since the roller 41 drives the leather to move, when the direction of the leather is offset, the leather will drive the roller 41 to deflect. The above-mentioned magnet 2 43 and magnet 1 22 play an auxiliary role. When the roller 41 deflects, the coarse electric push rod 57 contracts and corrects the leather. During the contraction of the coarse electric push rod 57, the magnet 2 43 and magnet 1 22 approach each other. Under the condition of magnetic attraction, the magnet 2 43 and magnet 1 22 are realigned, which serves the purpose of returning the roller 41 to its original position and correcting the rolling direction of the roller 41.

[0036] When the thick electric push rod 47 is extended to the longest, the roller 41 just contacts the leather. And due to the existence of the thick electric push rod 47, when the length of the thick electric push rod 47 remains unchanged, the range of activity of the base 4 can only swing left and right.

[0037] Two fixed blocks 6 are fixedly inserted at the front end of the base plate 1, an elastic belt 7 is fixedly installed between the two fixed blocks 6, a powder cake 8 is inserted into the fixed blocks 6, and the powder cake 8 passes through the fixed blocks 6 to contact the leather surface, and the elastic belt 7 is pressed on the powder cake 8. The powder cake 8 is used to draw lines on the leather.

[0038] A through slot is provided at the center of the fixed block 6, and the powder cake 8 passes through the slot. Grooves are symmetrically provided on both sides of the inner wall of the slot. A second pressure sensing unit 61 is fixedly installed at the bottom of the inner wall of the groove, and a lifting module 62 is fixedly installed on the second pressure sensing unit 61. A motor-driven pressing wheel 63 is fixedly installed on the lifting module 62, and the pressing wheel 63 contacts the side of the powder cake 8.

[0039] The elastic belt 7 is always in a stretched state, and the elastic belt 7 applies downward pressure to the powder cake 8, so that the powder cake 8 is always in contact with the leather. The lifting module 62 is a conventional technical means, so it is not described in detail. The two pressure wheels 63 clamp the powder cake 8, and there are anti-slip grooves on the surface of the pressure wheels 63. When the elastic belt 7 applies a downward force to the powder cake 8, the pressure wheel 63 descends together with the powder cake 8, and the lifting module 62 applies pressure to the pressure sensing unit 2 61. When the pressure sensed by the pressure sensing unit 2 61 exceeds the preset value, the pressure sensing unit 2 61 transmits information to the computer terminal. At this time, the pressure wheel 63 rotates slightly to lift the powder cake 8 upward to prevent the lower end of the powder cake 8 from pressing the leather and causing the leather to be unable to move.

[0040] The substrate 1 is symmetrically provided with a second through slot 12, which is located between the two first through slots 11. A second frame 3 is fixedly installed on the top of the substrate 1 and above the second through slot 12. An image capture module 31 is fixedly installed in the second frame 3. A baffle 14 is welded in the second through slot 12, and the working end of the image capture module 31 faces the baffle 14.

[0041] The baffle 14 is aligned with the powder 8 and is located on the same straight line. When the leather is not deflected during movement, the baffle 14 just covers the line drawn by the powder 8. When the leather is deflected during movement, the baffle 14 cannot completely cover the line, and the image is captured by the image capture module 31, and the information is transmitted to the computer terminal, which plays a role in auxiliary detection and improves the detection accuracy.

[0042] The front and rear ends of the base plate 1 are provided with slideways 13, and two drive seats 5 are slidably fitted in the slideways 13. The drive seats 5 can move along the slideways 13, and a thin electric push rod 51 is fixedly installed on the drive seats 5. The movable end of the thin electric push rod 51 is downwardly directed to contact the leather. When the thick electric push rod 47 is retracted, the thin electric push rod 51 is extended to contact the leather, and the drive seat 5 moves to reset the leather, thereby achieving the purpose of correcting the leather.

[0043] The sewing machine is also fixedly equipped with a control module, which is electrically connected to various electronic components and a computer terminal. After receiving the information, the computer terminal uses the control module to control the operation of various electronic components. Since this is a conventional technical means, it will not be described in detail.

[0044] In summary, the intelligent stitch management device of the leather sewing machine is composed of a substrate 1, a frame 2, a base 4, a roller 41, and a thick electric push rod 47. The roller 41 is used to replace the traditional manual hand pushing of the leather. Since the roller 41 rotates at a constant speed, the perforation distance of the leather is further controlled to be the same. Pressure sensing units 42 are provided on both sides of the base 4. The pressure sensing units 42 cooperate with the extension part 15 of the substrate 1 to sense whether the leather is deflected during movement.

[0045] In addition, the frame 1 2 is connected to a connecting strip 21, the lower end of the connecting strip 21 is connected to a magnet 1 22, and the base 4 is connected to a magnet 2 43. The cooperation between the magnet 1 22 and the magnet 2 43 can play a role in readjusting the roller 41. The base plate 1 is also fixedly installed with a frame 2 3, an image capture module 31, and a baffle 14, which serve the purpose of auxiliary detection, increase the accuracy of detecting whether the leather is offset, and ensure that the stitches are normal and straight.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
