Description

Technical Field

[0001] The invention relates to the technical field of clothing processing equipment, and in particular to a thread breakage detection device for an automatic button winding machine. Background Art

[0002] With the continuous development of the clothing industry, the requirements for automation and intelligence in clothing production are getting higher and higher. When a button machine or a manual button is used to fix four-hole, two-hole or mushroom buttons on clothes with sewing thread, if a certain space is not left between the button and the fabric, it will be very difficult to button the button, and the button will be stretched after fastening, and the fabric attached to the button of the clothes will leave ugly indentations and wrinkles. Therefore, people sometimes deliberately leave a gap between the button and the fabric when buttoning. In this way, the button cannot be nailed firmly, it is easy to fall off, and it cannot stand upright on the fabric, affecting the appearance. At the same time, the four-hole button is fixed on the fabric by four groups of sewing threads, which will still stretch the button. In order to make the button nails firm and beautiful, in the prior art, a manual winding method is used to combine the scattered four groups of wires into a thick wire. The disadvantages of this manual winding method are: slow winding speed and poor consistency. In order to speed up the winding speed, people have made a knotting winding machine, but the existing winding machine uses sewing thread to tie the four groups of wire buttons together in a knotted manner. This method is easy to fall apart, and it cannot achieve the purpose of locking the button thread and preventing the buttons from falling off. In addition, the knotting method will leave two thread tails when trimming the edges, which need to be trimmed manually. Although it has greatly improved the efficiency compared to the original pure manual processing, it still cannot meet the needs of mass clothing production and high-quality clothing technology. For this reason, automatic hot-melt button winding machines came into being, such as the Chinese patent document: Publication number "CN110820187A", which discloses an invention named "An intelligent fully automatic hot-melt button winding machine", and publication number "CN203393413U", which discloses a hot-melt button winding machine, etc. However, the full-automatic hot-melt button winding machine still has the following shortcomings during actual use: when the wire supply of the hot-melt button winding machine is broken, it cannot be effectively detected, because the wire of the hot-melt button winding machine is an elastic elastic wire, and the stretching multiple of the elastic wire is high. Therefore, when pulling the winding sewing thread, there is a Hall sensor detecting that the elastic wire often does not move, resulting in frequent false alarms, and it is impossible to effectively detect whether the elastic wire of the button winding is broken. The operating worker will not check whether the winding is completed after the winding is completed, so the false alarm requires stopping the machine to open it for inspection, resulting in low efficiency or continuing to work without knowing that the wire is broken, etc., which is useless after discovery. Therefore, how to effectively and accurately detect whether the elastic winding supply of the hot-melt button winding machine is broken and issue an alarm. Summary of the invention

[0003] Therefore, in view of the above problems, the present invention proposes a thread breakage detection device for an automatic button winding machine, which has a simple and reasonable structure and can effectively and accurately detect whether the elastic thread of the button winding is broken, thereby improving work efficiency.

[0004] To solve this technical problem, the present invention adopts the following scheme: a thread break detection device for an automatic button winding machine, comprising an alarm, a sensor and a fixed frame, and also comprising a force-applying mechanism and a thread pressing mechanism, wherein the fixed frame is arranged below the winding mechanism of the automatic button winding machine, and the thread pressing mechanism comprises a fixed shaft, a thread pressing rod, a baffle and a swing arm, wherein the fixed shaft is arranged on the upper part of the fixed frame, and the middle part of the swing arm is rotatably sleeved on the fixed shaft, the thread pressing rod and the baffle are respectively fixed to the two free ends of the swing arm, and the thread pressing rod faces and presses the yarn after the thread clamping mechanism of the automatic button winding machine clamps the yarn, the force-applying mechanism is arranged on the fixed frame, and the force-applying mechanism floats the baffle upwards and causes the thread pressing rod to press the yarn downwards through the swing arm to detect whether the yarn is broken, and the sensor is arranged on one side of the baffle to detect the position information of the floating position of the baffle and send the detection information to the alarm.

[0005] Furthermore, the force-applying mechanism is an air blowing mechanism, and an air outlet of the air blowing mechanism blows air toward the baffle to make the baffle float upward.

[0006] Furthermore, the blowing mechanism passes through one side of the fixing frame and blows air toward the baffle through the right-angled air outlet.

[0007] Furthermore, it also includes a second swing arm, wherein the middle parts of the swing arm and the second swing arm are rotatably mounted on both ends of the fixed shaft, one end of the swing arm and the second swing arm are respectively connected to the two ends of the wire pressing rod, and the other ends of the swing arm and the second swing arm are respectively connected to both sides of the baffle.

[0008] Furthermore, the force-applying mechanism is a push rod, and the push rod pushes upward toward the baffle at intervals to make the baffle float upward.

[0009] By adopting the above-mentioned technical scheme, the beneficial effect of the present invention is as follows: by arranging the wire breakage detection device of the present invention under the winding mechanism of the button automatic winding machine to detect the yarn clamped by the wire clamping mechanism, that is, by applying power to the baffle through the force-applying mechanism so that the baffle floats slightly upwards, and the wire pressing rod presses down the yarn clamped by the wire clamping mechanism of the button automatic winding machine through the swing arm; if the yarn is not broken, the wire pressing rod is subject to the resistance of the yarn so that the position of the baffle cannot reach the detection position of the sensor alarm; if the yarn is broken, the wire pressing rod has no yarn resistance and the baffle reaches the alarm position detected by the sensor under the push of the force-applying mechanism, then the alarm sounds, and the button winding machine can accurately detect whether the wire breakage is broken or not, and the matching action of the force-applying mechanism and the wire clamping mechanism can be set to accurately detect whether the winding yarn of each button is broken, effectively ensuring the winding efficiency of the button, and the structure is simple and reasonable. Through further arrangement, that is, the force-applying mechanism adopts a blowing mechanism, it is more convenient to control the force applied to the baffle, and it is more convenient to use and can be widely promoted and applied. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1It is a partial structural schematic diagram of an embodiment of the present invention combined with an automatic button winding machine. DETAILED DESCRIPTION

[0011] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0012] refer to Figure 1 The preferred device for detecting broken wires in an automatic button winding machine of the present invention comprises an alarm, a sensor and a fixed frame 1, a force applying mechanism 2 and a wire pressing mechanism 3, wherein the fixed frame 1 is arranged below the winding mechanism 4 of the automatic button winding machine, and the wire pressing mechanism 3 comprises a fixed shaft 31, a wire pressing rod 32, a baffle 33 and a swing arm 34 and a second swing arm, wherein the fixed shaft 31 is arranged on the upper part of the fixed frame 1, and the middle parts of the swing arm 34 and the second swing arm are rotatably sleeved on the two ends of the fixed shaft 31, and one end of the swing arm 34 and the second swing arm is connected to the two ends of the wire pressing rod 32, respectively, and the swing arm 34 and The other end of the second swing arm is respectively connected to both sides of the baffle 33, and the wire pressing rod 32 faces and presses the yarn 6 after the wire clamping mechanism 5 of the button automatic winding machine clamps the yarn. The force-applying mechanism 2 is an air blowing mechanism, and the air blowing mechanism passes through one side of the fixed frame 1 and blows air toward the baffle 33 through a right-angle air outlet. The air outlet of the air blowing mechanism blows air toward the baffle 33 to make the baffle 33 float upward, and the wire pressing rod 32 presses down the yarn 6 through the swing arm 34 to detect whether the yarn 6 is broken. The sensor is arranged on one side of the baffle 33 to detect the floating position information of the baffle 33 and send the detection information to the alarm.

[0013] The force-applying mechanism in the present invention may also be a push rod or other power mechanism that can apply slight upward floating force to the baffle at intervals, such as the push rod at intervals pushing up the baffle to make the baffle float upward.

[0014] The present invention arranges the thread breakage detection device of the present invention under the winding mechanism of the button automatic winding machine to detect the yarn clamped by the thread clamping mechanism, that is, the force-applying mechanism applies power to the baffle plate so that the baffle plate slightly floats upwards and the thread pressing rod presses down the yarn clamped by the thread clamping mechanism of the button automatic winding machine through the swing arm. If the yarn is not broken, the thread pressing rod is subject to the resistance of the yarn so that the position of the baffle plate cannot reach the detection position of the sensor alarm. If the yarn is broken, the thread pressing rod has no yarn resistance and the baffle plate reaches the alarm position detected by the sensor under the push of the force-applying mechanism, then the alarm device sounds an alarm, thereby realizing accurate detection of thread breakage of the button winding machine without being affected by the elastic stretching of the yarn. By setting the matching actions of the force-applying mechanism and the thread clamping mechanism, it is possible to accurately detect whether the winding yarn of each button is broken, thereby effectively ensuring the working efficiency of the button winding. The structure is simple and reasonable. Through further arrangement, that is, the force-applying mechanism adopts the blowing mechanism, it is more convenient to control the force applied to the baffle plate, so it is more convenient to use and can be widely promoted and applied.
