Description

An automatic thread-breaking device for a trouser knotting machine Technical Field

[0001] This utility model relates to the technical field of garment production, and in particular to an automatic thread-breaking device for a trouser knotting machine. Background Technology

[0002] A knotting machine is a type of sewing machine, mainly used to reinforce key stress-bearing parts of trousers, such as the placket, pocket opening, and trouser loops. It improves the durability of clothing through high-density stitching and has an automatic thread winding function. After knotting, the knotting machine needs to cut the sewing thread. In the prior art, many sewing machine thread-breaking mechanisms, such as those with patent application numbers 201721007241.4, 202320168541.X, and 202223137037.8, all basically break the thread by cutting it with a blade or scissors. However, these mechanisms have the following problems in use: for some sewing threads that are braided, there is a risk of the thread end becoming loose after cutting it with scissors. Workers need to use a lighter to melt the cut thread end to prevent it from unraveling. Melting the thread end after cutting it increases the labor intensity and is inconvenient to use. Therefore, there is a need for a thread-breaking device that can melt the thread end while cutting the thread. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides an automatic thread-breaking device for trouser knotting machines that can melt the thread end while breaking the thread, which is easy to use, has low labor intensity, and is highly practical.

[0004] This utility model discloses an automatic thread-cutting device for a trouser knotting machine, comprising a base plate and a knotting machine, with the knotting machine mounted on the upper part of the base plate; it also includes a thread-burning pen and a moving mechanism, with the thread-burning pen mounted on the moving mechanism for moving the thread-burning pen; after the trousers are knotted on the knotting machine, the moving mechanism moves the thread-burning pen to the end of the knotted trousers, allowing the thread-burning pen to contact the sewing thread, and the high temperature generated by the thread-burning pen cuts the thread end. The high temperature generated during thread cutting also melts the thread end, preventing the thread from opening. It is convenient to use and highly practical.

[0005] Preferably, the moving mechanism includes a forward and backward moving mechanism, a mounting plate, a fixed plate, a lifting plate, and an electric slide rail A. The thread burner is fixedly mounted on the mounting plate, the mounting plate is fixedly mounted on the fixed plate, the fixed plate is fixedly mounted on the lifting plate, the lifting plate is mounted on the electric slide rail A, and the electric slide rail A is used to move the lifting plate forward and backward. The electric slide rail A is mounted on the forward and backward moving mechanism, which is used to move the electric slide rail A forward and backward. After the knotting machine finishes knotting the trousers, the height of the lifting plate is adjusted by the electric slide rail A. The lifting plate, through the fixed plate, causes the mounting plate to adjust the height of the thread burner, so that the height of the thread burner is adjusted to a suitable height for cutting the thread end. Then, the forward and backward moving mechanism causes the electric slide rail A to move the lifting plate forward and backward. The lifting plate causes the fixed plate and the mounting plate to move forward, and the mounting plate causes the thread burner to move forward. During the forward movement, the thread burner contacts the sewing thread at the knot and cuts the sewing thread by the thread burner, while simultaneously melting the thread end.

[0006] Preferably, the forward and backward moving mechanism includes a support plate, an electric slide rail B, and a sliding plate. The electric slide rail B is fixedly mounted on the base plate via the support plate, and the sliding plate is mounted on the electric slide rail B. The electric slide rail B is used to move the sliding plate forward and backward. The electric slide rail A is fixedly mounted on the upper end of the sliding plate. When the thread-burning pen moves forward and backward, the electric slide rail B is opened, and the electric slide rail B drives the sliding plate to move in the forward and backward direction. This causes the electric slide rail A to drive the lifting plate and the fixed plate to move in the forward and backward direction, which in turn causes the mounting plate to drive the thread-burning pen to move in the forward and backward direction, so that the thread-burning pen contacts the sewing thread at the knot and cuts the sewing thread through the thread-burning pen.

[0007] Preferably, it also includes an air purifier, a gas supply hose, and an air intake pipe. The air purifier is mounted on the base plate, and the air supply hose is installed at the input end of the air purifier. The air intake pipe is installed at the input end of the gas supply hose and is mounted on the mounting plate. Since some irritating gases are generated when the sewing thread is melted and broken with a hot-melt pen, after a long period of work, turning on the air purifier allows the air at the broken point to enter the air purifier for purification through the air intake pipe and the gas supply hose, ensuring the quality of the workshop air and high environmental protection.

[0008] Preferably, the support plate is provided with a reinforcing plate; this feature improves the stability of the support plate during use.

[0009] Preferably, an infrared thermometer is provided on the mounting plate, with the detection end of the infrared thermometer pointing towards the wire-burning pen; this arrangement facilitates the monitoring of the wire-burning pen's temperature.

[0010] Preferably, the upper end of the knotting machine is equipped with a light; this arrangement makes the upper part of the knotting machine brighter, facilitating the observation of its working status.

[0011] Compared with the prior art, the advantages of this utility model are: it can melt the wire end while breaking the wire, which is convenient to use, has low labor intensity, and is highly practical. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] As shown in Figures 1 to 5, the automatic thread-cutting device for the trouser knotting machine of this utility model includes a base plate 1, a knotting machine 2, a thread-burning pen 3, and a moving mechanism. The knotting machine 2 is installed on the upper end of the base plate 1, and the thread-burning pen 3 is installed on the moving mechanism. The moving mechanism is used to move the thread-burning pen 3. After the trousers are knotted on the knotting machine 2, the moving mechanism moves the thread-burning pen 3 to the end of the knotted trousers, so that the thread-burning pen 3 comes into contact with the sewing thread. The high temperature generated by the thread-burning pen 3 cuts the thread end. At the same time, the high temperature generated during the thread cutting melts the thread end to prevent the thread from opening. It is convenient to use and highly practical.

[0021] As shown in Figures 1, 2, and 3, the moving mechanism includes a forward and backward moving mechanism, a mounting plate 4, a fixed plate 5, a lifting plate 6, and an electric slide rail A7. The wire burner 3 is fixedly mounted on the mounting plate 4, which in turn is fixedly mounted on the fixed plate 5. The fixed plate 5 is fixedly mounted on the lifting plate 6, which is mounted on the electric slide rail A7. The electric slide rail A7 is used to move the lifting plate 6 forward and backward. The electric slide rail A7 is mounted on the forward and backward moving mechanism, which is used to move the electric slide rail A7 forward and backward. After the knotting machine 2 finishes knotting the trousers, it... The electric slide rail A7 adjusts the height of the lifting plate 6. The lifting plate 6, through the fixed plate 5, causes the mounting plate 4 to adjust the height of the thread burner 3, so that the height of the thread burner 3 is adjusted to a suitable height for cutting the thread end. Then, through the forward and backward movement mechanism, the electric slide rail A7 moves the lifting plate 6 back and forth. The lifting plate 6 moves the fixed plate 5 and the mounting plate 4 forward. The mounting plate 4 moves the thread burner 3 forward. During the forward movement, the thread burner 3 comes into contact with the sewing thread at the knot and cuts the sewing thread by the thread burner 3, while simultaneously melting the thread end.

[0022] As shown in Figure 3, the forward and backward moving mechanism includes a support plate 8, an electric slide rail B9, and a sliding plate 10. The electric slide rail B9 is fixedly installed on the base plate 1 via the support plate 8, and the sliding plate 10 is installed on the electric slide rail B9. The electric slide rail B9 is used to move the sliding plate 10 forward and backward. The electric slide rail A7 is fixedly installed on the upper end of the sliding plate 10. When the thread-burning pen 3 moves forward and backward, the electric slide rail B9 is opened, and the electric slide rail B9 drives the sliding plate 10 to move in the forward and backward direction. This causes the electric slide rail A7 to drive the lifting plate 6 and the fixing plate 5 to move in the forward and backward direction, which in turn causes the mounting plate 4 to drive the thread-burning pen 3 to move in the forward and backward direction, so that the thread-burning pen 3 contacts the sewing thread at the knot and cuts the sewing thread through the thread-burning pen 3.

[0023] A reinforcing plate 14 is provided on the support plate 8; the above-mentioned arrangement improves the stability of the support plate 8 during use.

[0024] An infrared thermometer is mounted on the mounting plate 4, with its detection end pointing towards the wire-burning pen 3; this arrangement facilitates the monitoring of the temperature of the wire-burning pen 3. A light is installed at the top of the knotting machine 2.

[0025] Example 2

[0026] As shown in Figures 1, 2, and 4, an air purifier 11, an air supply hose 12, and an air intake pipe 13 are added. The air purifier 11 is installed on the base plate 1. The air supply hose 12 is installed at the input end of the air purifier 11, and the air intake pipe 13 is installed at the input end of the air supply hose 12. The air intake pipe 13 is installed on the mounting plate 4. Since some irritating gases are generated when the sewing thread is melted and broken by the hot-melt pen 3, after a long period of work, the air purifier 11 is turned on, so that the air at the broken point enters the air purifier 11 through the air intake pipe 13 and the air supply hose 12 in sequence for purification, ensuring the air quality in the workshop and achieving high environmental protection.

[0027] The thread-burning pen 3, electric slide rail A7, electric slide rail B9, and air purifier 11 of the automatic thread-breaking device for the trouser knotting machine of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
