DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Please refer to Figure 1-7 Figure 1-7 For a multifunctional intelligent sewing auxiliary device provided by the present utility model, an electric sewing machine body 1, a housing 2 and a thread spool 3 installed on the top of the electric sewing machine body 1, and a thread roller 4 placed on the thread spool 3;

[0020] It is characterized in that it further includes: an elastic pressure rod 5 fixed on the inner side wall of the housing 2, one end of the elastic pressure rod 5 is fixed with a mounting bracket 6, and a pressure roller 7 is rotatably installed on the top of the mounting bracket 6, so that the pressure roller 7 always fits on the thread roller 4 under the action of the elastic pressure rod 5; a top rod 8 is further installed on the mounting bracket 6, and an alarm component 9 cooperating with the top rod 8 is installed on the inner wall of the housing 2; one end of the outer wall of the top of the housing 2 is provided with a fixing port 10, and a movable groove 11 is provided on the inner wall of one side of the fixing port 10, and a sealing component 12 is provided in the fixing port 10.

[0021] When the electric sewing machine body 1 works, the thread on the thread roller 4 is drawn for use, so that the winding thickness on the thread roller 4 becomes thinner, and then the overall diameter of the thread roller 4 becomes smaller. The pressure roller 7 can be gently pressed on the surface of the thread roller 4 by the elastic pressure rod 5, and at the same time, it does not affect the rotation of the thread roller 4 when drawing the thread. When the diameter of the thread roller 4 becomes smaller, the mounting bracket 6 and the pressure roller 7 automatically move to one side of the thread roller 4 under the action of the elastic pressure rod 5, so that the pressure roller 7 always adheres to the surface of the thread roller 4; the mounting bracket 6 drives the top rod 8 to move during the movement. When the winding thickness on the thread roller 4 gradually becomes thinner and is almost used up, the mounting bracket 6 drives the top rod 8 to move a certain distance, and the top rod 8 touches the induction structure in the alarm component 9, and the alarm component 9 issues an alarm to remind the workers that the thread on the thread roller 4 is almost used up and the thread roller 4 should be replaced in time. The worker can push the sealing component 12 to open the top of the housing 2, which is convenient for removing the thread roller 4 from the thread spool 3 for replacement. During the process of being pushed and moved, the sealing component 12 will drive the mounting bracket 6 to move and squeeze the elastic pressure rod 5, which is convenient for moving the pressure roller 7 away from the outer wall of the thread roller 4, facilitating the removal of the thread roller 4 for replacement.

[0022] The elastic pressure rod 5 includes a square tube 501, a square plate 502 is sleeved inside the square tube 501, a compression spring 503 is further provided between the square plate 502 and the square tube 501, and both ends of the compression spring 503 are respectively connected to the square plate 502 and the square tube 501.

[0023] It should be noted here that: the compression spring 503 pushes the square plate 502 out of the square tube 501, and then gently presses the pressure roller 7 on the surface of the thread roller 4.

[0024] The alarm component 9 includes a controller 901, a mounting plate 902, an alarm 904 and a pressure sensor 903 installed on the outer wall of one side of the mounting plate 902. The pressure sensor 903 and the alarm 904 are both connected to the controller 901 through signal lines.

[0025] It should be noted here that: the push rod 8 moves toward the side of the wire roller 4 along with the mounting frame 6, and touches the pressure sensor 903 during the movement. The pressure sensor 903 transmits the pressure signal to the controller 901, and the controller 901 controls the alarm 904 to sound an alarm.

[0026] The sealing assembly 12 includes a sealing plate 1201, a push plate 1202 fixed on the bottom outer wall of the sealing plate 1201, a toggle plate 1203 installed on the top of the sealing plate 1201, a connecting rod 1204 installed on the outer wall of one side of the toggle plate 1203, and a movable plate 1205 rotatably installed on the connecting rod 1204.

[0027] It should be noted that the movable plate 1205 can be rotated so that the bottom of the movable plate 1205 faces upward, and the sealing plate 1201 can be pushed into the movable groove 11 to open the fixing opening 10, so that the staff can easily replace the wire roller 4 through the fixing opening 10. During the movement of the sealing plate 1201, the push plate 1202 at the bottom thereof drives the mounting frame 6 to move, squeezes the elastic pressure rod 5, and conveniently removes the pressure roller 7 from the outer wall of the wire roller 4, so as to facilitate the removal of the wire roller 4 for replacement.

[0028] The outer wall of one side of the housing 2 is provided with a thread outlet 13 ; the thread on the thread roller 4 can be fed to the electric sewing machine body 1 through the thread outlet 13 .

[0029] The push rod 8 is at the same height as the center point of the pressure sensor 903. The push rod 8 can easily push against the pressure sensor 903 during the movement.

[0030] It should be noted that, when sewing the sewing thread, the thread ends may be cut short and need to be reconnected, so it is considered to add an automatic joint to the needle of the electric sewing machine body 1. Since the automatic joint is a prior art, the utility model will not elaborate on the structure of the automatic joint.

[0031] Working principle: When the electric sewing machine body 1 is working, the thread on the thread roller 4 is drawn out for use, so that the thickness of the winding thread on the thread roller 4 becomes thinner, thereby making the overall diameter of the thread roller 4 smaller.

[0032] The compression spring 503 pushes the square plate 502 outward from the square tube 501, and then presses the pressure roller 7 lightly on the surface of the wire roller 4, while not affecting the wire drawing rotation of the wire roller 4.

[0033] When the diameter of the wire roller 4 decreases, the mounting bracket 6 and the pressure roller 7 automatically move towards the wire roller 4 under the action of the compression spring 503, so that the pressure roller 7 always adheres to the surface of the wire roller 4; the mounting bracket 6 drives the ejector rod 8 to move during the movement. When the winding thickness on the wire roller 4 gradually becomes thinner and is almost used up, the mounting bracket 6 drives the ejector rod 8 to move a certain distance, and touches the pressure sensor 903 during the movement. The pressure sensor 903 transmits the pressure signal to the controller 901, and the controller 901 controls the alarm 904 to give an alarm, reminding the workers that the winding on the wire roller 4 is almost used up and the wire roller 4 should be replaced in time.

[0034] When replacing the wire roller 4, the movable plate 1205 can be rotated so that the bottom of the movable plate 1205 faces upwards. At this time, the sealing plate 1201 can be pushed into the movable groove 11 to open the fixing port 10, facilitating the workers to replace the wire roller 4 through the fixing port 10; during the movement of the sealing plate 1201, the mounting bracket 6 is driven by the push plate 1202 at its bottom to push the square plate 502 into the square tube 501, facilitating the removal of the pressure roller 7 from the outer wall of the wire roller 4 and facilitating the removal of the wire roller 4 for replacement.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
