[0027] Reference Figures 1 to 3 The utility model discloses a button feeding mechanism of a suspender machine, comprising a movable seat 100, a left arm structure 200, a right arm structure 300 and a push rod 400. The movable seat 100 can move in the front-to-back direction and is located behind the sewing mechanism; the left arm structure 200 and the right arm structure 300 are arranged on the front end surface of the movable seat 100, the left arm structure 200 and the right arm structure 300 have the same structure and are arranged symmetrically on the left and right sides, a left limiting groove is arranged on the right end surface of the left arm structure 200, and a right limiting groove 310 is arranged on the left end surface of the right arm structure 300, the length directions of the left limiting groove and the right limiting groove 310 are both in the front-to-back direction, the left limiting groove and the right limiting groove 310 are respectively provided for the left and right ends of the I-shaped button to extend forward and backward, and the left arm structure 200 is provided with a left stop groove, and the right stop groove 310 is provided with a right stop groove 310. A left elastic member is provided at the front end, a left guide groove is provided at the bottom of the front end of the left limiting groove, a left buckle block is provided in the left guide groove, the left elastic member forces the left buckle block to move toward the right, a right elastic member 320 is provided at the front end of the right arm structure 300, a right guide groove 330 is provided at the bottom of the front end of the right limiting groove 310, a right buckle block 340 is provided in the right guide groove 330, the right elastic member 320 abuts against the right buckle block 340 to force the right buckle block 340 to move toward the left; the push rod 400 can be slidably provided on the movable seat 100 along the front and rear directions, and the front end of the push rod 400 is located between the left arm structure 200 and the right arm structure 300 to push the I-shaped buttons on the left arm structure 200 and the right arm structure 300 to the sewing station.
[0028] When it is necessary to deliver an I-shaped button to the sewing station, the vibration plate device and the feeding mechanism can be used to first deliver a single I-shaped button from front to back into the left limit groove and the right limit groove 310, and the push rod 400 is behind the I-shaped button. It can be seen that the four corners of the I-shaped button are all rounded structures. When the I-shaped button enters the left limit groove and the right limit groove 310 from front to back, the left end of the I-shaped button abuts on the left buckle block and presses the left buckle block into the left guide groove, the left elastic member is deformed and the left buckle block continues to abut against the left end of the I-shaped button; similarly, the right end of the I-shaped button abuts on the right buckle block 340 and presses the right buckle block 340 into the right guide groove 330, the right elastic member 320 is deformed and the right buckle block 340 continues to abut against the right end of the I-shaped button. The left arm structure 200 and the right arm structure 300 are symmetrically arranged, the left elastic member and the right elastic member 320 have the same elasticity, and the left pressing block and the right pressing block 340 push the left and right ends of the I-shaped button respectively, so that the position of the I-shaped button is centered and remains unchanged, avoiding the I-shaped button from being displaced or falling off, thereby completing the limitation of the I-shaped button.
[0029] Initially, the button feeding mechanism is behind the sewing mechanism (sewing station) and away from the sewing mechanism, so that the vibration plate device and the feeding mechanism can first feed the single I-shaped button from front to back into the left limiting groove and the right limiting groove 310. After the left arm structure 200 and the right arm structure 300 stably limit the I-shaped button, the push rod 400 remains behind the I-shaped button, driving the moving seat 100 to move forward, and the moving seat 100 carries the left arm structure 200 and the right arm structure 300 to move forward, thereby moving the I-shaped button to the area close to the sewing station, and then driving the push rod 400 to move from back to front, and the push rod 400 pushes the I-shaped buttons on the left arm structure 200 and the right arm structure 300 to the sewing station.
[0030] It can be understood that the left arm structure 200 and the right arm structure 300 are both plate-shaped, and both have an upper side surface, a lower side surface, a front end surface, a rear end surface, a left end surface and a right end surface, and the front end surfaces of the left arm structure 200 and the right arm structure 300 are flush.
[0031] A first guide angle is provided between the left limit groove and the front end surface of the left arm structure 200, and a second guide angle is provided between the right limit groove 310 and the front end surface of the right arm structure 300. The setting of the first guide angle and the second guide angle facilitates the I-shaped button to align the left limit groove and the right limit groove 310.
[0032] See also Figure 1In some embodiments, the button delivery mechanism further includes a mounting seat 500, which is used to be connected to the body of the strap machine and is located behind the sewing mechanism. The movable seat 100 is connected to the mounting seat 500 through a sliding mechanism 600, and the sliding direction of the sliding mechanism 600 is the front-back direction. The sliding mechanism 600, the movable seat 100, the left arm structure 200, the right arm structure 300 and the push rod 400 can be first installed on the mounting seat 500, and then the mounting seat 500 is fixedly connected to the body of the strap machine, so as to facilitate the installation of the entire button delivery mechanism.
[0033] Due to the setting of the sliding mechanism 600, the moving seat 100, the left arm structure 200, the right arm structure 300 and the push rod 400 can easily move in the front-to-back direction on the mounting seat 500, reducing the resistance encountered during movement. The sliding mechanism 600 includes a guide rail and a slider that cooperate with each other. The guide rail is arranged on the mounting seat 500 and the length of the guide rail is in the front-to-back direction. The slider is connected to the moving seat 100.
[0034] In some of the embodiments, the movable seat 100 is connected to a first front-rear driving mechanism (not shown in the figure), the first front-rear driving mechanism drives the movable seat 100 to move forward so that the left arm structure 200 and the right arm structure 300 carry the I-shaped buttons toward the sewing station, and the first front-rear driving mechanism drives the movable seat 100 to move backward so that the left arm structure 200 and the right arm structure 300 are away from the sewing station.
[0035] The first front-rear driving mechanism can be a first cylinder, the cylinder body of which is fixedly connected to the main body of the shoulder strap machine, and the piston rod of which is connected to the movable seat 100 .
[0036] In some of the embodiments, the push rod 400 is connected to a second front-rear driving mechanism (not shown in the figure). When the second front-rear driving mechanism drives the push rod 400 to move forward, the push rod 400 pushes the I-shaped buttons on the left arm structure 200 and the right arm structure 300 to the sewing station; when the second front-rear driving mechanism drives the push rod 400 to move backward, there is no obstacle between the left limit groove and the right limit groove 310, and the new I-shaped button can enter the left limit groove and the right limit groove 310, waiting for the push rod 400 to push the new I-shaped button to the sewing station.
[0037] The second front-rear driving mechanism may be a second cylinder, the cylinder body of which is fixedly connected to the mounting seat 500 , and the piston rod of which is connected to the push rod 400 .
[0038] See also Figure 2 and Figure 3In some of the embodiments, a right receiving groove 350 is provided on the right end surface of the right arm structure 300, and the right receiving groove 350 is connected to the right limiting groove 310 through the right guide groove 330. The right elastic member 320 is rod-shaped or plate-shaped. The right elastic member 320 is arranged in the right receiving groove 350. The right receiving groove 350 serves to store the right elastic member 320, and the right guide groove 330 serves to guide the right buckle block 340.
[0039] The right end of the right buckle block 340 extends to the right receiving groove 350 and abuts against the front end of the right elastic member 320. The front end of the right elastic member 320 acts on the right buckle block 340. The left end of the right buckle block 340 passes through the right guide groove 330 and extends into the right limit groove 310. The left end of the right buckle block 340 abuts against the I-shaped button and drives the I-shaped button to move toward the left, thereby achieving the function of pushing the I-shaped button.
[0040] In some of the embodiments, a hook is provided at the rear end of the right elastic member 320 , and the hook is hooked on the side wall of the right receiving groove 350 , thereby fixing the right elastic member 320 on the right arm structure 300 .
[0041] It is understandable that a connecting hole is provided between the rear end of the right receiving slot 350 and the rear end of the right limiting slot 310 , and the rear end of the right elastic member 320 is bent into an L-shaped hook portion, which passes through the connecting hole.
[0042] See also Figure 3 In some of the embodiments, a blocking portion is provided at the right end of the right buckle block 340, which can be against the bottom of the right receiving groove 350 to limit the position of the right buckle block 340 moving to the left, thereby preventing the entire right buckle block 340 from passing through the right guide groove 330.
[0043] The front and rear ends of the left end of the right buckle block 340 are both provided with a third chamfer. When the I-shaped button extends into the right limit groove 310, the I-shaped button rests on the third chamfer, which facilitates driving the right buckle block 340 to retract into the right guide groove 330, thereby reducing the resistance encountered by the I-shaped button when it extends into the right limit groove 310.
[0044] Similarly, the structure and installation method of the left arm structure 200 are the same as those of the right arm structure 300, and no redundant introduction is given here.
[0045] In some of the embodiments, a connecting column 700 is provided on the movable seat 100, and the length of the connecting column 700 extends in the front-to-back direction. A support plate 710 is provided at the front end of the connecting column 700. The rear ends of the left arm structure 200 and the right arm structure 300 are connected to the support plate 710 through a first fastener, and the left arm structure 200 and the right arm structure 300 are quickly installed and disassembled through the first fastener.
[0046] In some of the embodiments, the connecting column 700 is provided with a center hole (not shown in the figure), the support plate 710 is connected to a retaining block 800, the retaining block 800 is provided with a guide hole (not shown in the figure), the guide hole is coaxially arranged with the center hole, the push rod 400 is passed through the guide hole and the center hole, the diameter of the push rod 400 is smaller than the diameter of the center hole, so that the push rod 400 can pass through the center hole, the diameter of the push rod 400 matches the guide hole, the push rod 400 is limited in the guide hole and makes the push rod 400 and the connecting column 700 coaxial.
[0047] In some of the embodiments, a flange is provided at the front end of the push rod 400, the diameter of the flange is larger than the diameter of the guide hole, and the flange limits the backward position of the push rod 400 to prevent the entire push rod 400 from exiting the guide hole and the center hole from front to back.
[0048] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
