Description

Technical Field

[0001] The utility model relates to the technical field of button sewing machines, and more particularly to a buttoning conveying mechanism of a button sewing machine. Background Art

[0002] A button sewing machine is an automated device that rivets buttons onto garments, such as labels, tags, and caps. The most commonly used buttons are disc-shaped buttons with two or four holes (also known as flat buttons). By replacing various specialized accessories, a single button sewing machine can sew various types of buttons, including shank buttons, metal buttons, snap buttons, shank buttons, and official buttons.

[0003] The existing button-stitching machine mainly includes a feeding device and a button-stitching device; wherein, the button-stitching device includes a mold base and a punch rod, the mold base is equipped with a lower button, and the punch rod is equipped with an upper button. After the punch rod punches down, the upper and lower buttons are pressed together. The feeding device generally includes a feeding vibration plate, which uses the vibration plate to deliver the upper and lower buttons separately. The existing button-stitching machine generally has a punch rod that moves back and forth. When moving backward, the punch rod can receive the upper button. When moving forward, the punch rod corresponds to the mold base and can punch downward. However, this way of moving the punch rod makes the structure more complicated. The punch rod component must be able to move back and forth and punch up and down. At the same time, the pressure of the upper and lower punching is relatively large, resulting in a complex internal drive structure and prone to failure. Therefore, it is urgent to provide a conveying mechanism that can transport the upper button sent by the feeding device to the punch rod to simplify the movement of the punch rod. At the same time, the movement of the conveying mechanism should also be simple and reliable. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a button-up conveying mechanism for a button-sewing machine, which can convey the button-up to a punch rod and has a simple and reliable structure.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a button conveying mechanism of a button sewing machine, comprising a frame, a conveying platform that slides back and forth and a fixed material receiving channel is provided on the frame, a button seat that cooperates with the material receiving channel is provided on the conveying platform, the back and forth sliding of the conveying platform is used to drive the button seat away from or against the material receiving channel, a button pushing rod is slidingly provided on the conveying platform, when the button seat and the material receiving channel are against each other, the button pushing rod is used to push the button at the discharge position of the material receiving channel into the button seat, and the button pushing rod and the conveying platform have an alternating push-out state and a synchronous retraction state.

[0006] The present invention is further configured as follows: in the alternating pushing state, the button pushing rod first pushes the button into the button seat, and the conveying platform then moves the button seat to under the punch rod of the button sewing machine; in the synchronous retraction state, the button pushing rod and the conveying platform are synchronously retracted to their original positions.

[0007] The utility model is further configured as follows: the frame is provided with slide rails distributed in the front-rear direction, the slide rails are provided with a slide seat with an L-shaped structure, and the conveying platform is fixedly arranged on the slide seat.

[0008] The utility model is further configured as follows: a second slide rail and a second slide seat on the second slide rail are provided on the conveying platform, and the push-button rod is fixedly arranged on the second slide seat.

[0009] The utility model is further configured as follows: a first cylinder and a second cylinder are provided on the frame, the first cylinder is used for driving the conveying platform, and the second cylinder is used for driving the push rod.

[0010] The utility model is further configured as follows: an upward buckle feeding mechanism is provided on one side of the frame, and the discharge port of the upward buckle feeding mechanism is adapted to the feeding position of the material receiving channel.

[0011] The present invention is further configured as follows: a push buckle portion is provided at the front end of the push buckle rod, the push buckle portion includes an upper stop portion and an accommodating cavity, the accommodating cavity is adapted to the upper buckle, and the upper stop portion abuts against the upper end surface of the upper buckle.

[0013] In summary, the present invention has the following beneficial effects:

[0014] Compared with the prior art, the present invention provides a conveyor platform that moves forward and backward. The receiving channel on the conveyor platform receives the incoming bead and sends it to the bead seat via the push rod. The conveyor platform then moves forward to move the bead seat under the punch rod, allowing the punch rod to descend and take the bead. The conveyor platform then moves backward, leaving space for the punch rod to punch downward, and then receives the bead sent by the feeding device through the receiving channel. This ensures that the punch rod only moves up and down for punching, and the structure is simple and not prone to failure.

[0015] At the same time, the utility model is also provided with a push-button rod, and the push-button rod and the conveying platform have an alternating pushing state and a synchronous retraction state. In the alternating pushing state, the push-button rod first pushes the upper buckle into the upper buckle seat, and then maintains the difference, and the conveying platform moves forward again. While moving the upper buckle seat to the bottom of the punch rod, the position of the upper buckle seat and the push-button rod are separated again, and the position of the push-button rod and the upper buckle seat will be reset to the state when the push-button rod is not pushed out. In this way, the push-button rod and the conveying platform can be retracted at the same time in the synchronous retraction state. The structure is simple and reasonable, and the operating speed is faster, which helps to improve the conveying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] This embodiment discloses a button-up conveying mechanism of a button-stitching machine. Figure 1-5 As shown, the overall button sewing machine 14 includes a frame 101, and a conveyor platform 1 that slides forward and backward and a fixed material receiving channel 2 are provided on the frame 101. A buckle seat 3 that cooperates with the material receiving channel 2 is provided on the conveyor platform 1. The forward and backward sliding of the conveyor platform 1 is used to drive the buckle seat 3 away from or against the material receiving channel 2. A buckle push rod 4 is slidingly provided on the conveyor platform 1. When the buckle seat 3 and the material receiving channel 2 are against each other, the buckle push rod 4 is used to push the buckle 13 at the discharge position of the material receiving channel 2 into the buckle seat 3. The buckle push rod 4 and the conveyor platform 1 have an alternating push-out state and a synchronous retraction state.

[0024] Further, refer to Figure 2-4 In the alternating pushing state, the button push rod 4 first pushes the button 13 into the button seat 3, and the conveyor 1 then moves the button seat 3 to under the punch of the button sewing machine; in the synchronous retraction state, the button push rod 4 and the conveyor 1 are synchronously retracted to their original positions. Specifically, the alternating pushing state is that the button push rod 4 is extended first, and then the conveyor 1 is extended. The extension distances of the two are preferably the same. In this way, after the alternating pushing, the relative positions of the button push rod 4 and the conveyor 1 do not change (refer to Figure 2 and Figure 4 ), then retract synchronously to return to Figure 2The initial state of the push-button rod 4 and the conveyor platform 1 is simplified by setting the alternate push-out state and the synchronous retraction state. Assuming the most direct driving method is adopted, the push-button rod 4 must first extend and retract, and then the conveyor platform 1 must extend and retract again. The control needs to be done four times, and the process time will be longer. At the same time, in terms of structure, after the push-button rod 4 retracts, the conveyor platform 1 extends again, so the movement stroke of the push-button rod 4 on the conveyor platform 1 becomes longer, the moving structure needs to be longer, and the corresponding reserved movement space must also be larger, which will also be more complex in structure. Therefore, the alternate push-out and synchronous retraction of this embodiment are better in terms of control, process time and structure.

[0025] Furthermore, the frame 101 is provided with slide rails 5 distributed in the front and rear directions, and the slide rails 5 are provided with an L-shaped slide seat 6, and the conveyor 1 is fixedly provided on the slide seat 6. Through the above structure, the conveyor 1 is able to move forward and backward on the frame 101; Figure 1-2 The slide 6 is an L-shaped structure that is flipped upside down. The advantage is that the L-shaped bending setting allows a larger space to be left below the slide 6 to avoid other devices.

[0026] Furthermore, the conveyor platform 1 of this embodiment is provided with a second slide rail 11 and a second slide seat 12 mounted on the second slide rail 11. The push-and-lock rod 4 is fixedly mounted on the second slide seat 12. This structure enables the push-and-lock rod 4 to move on the conveyor platform 1. Furthermore, due to the alternating extension and synchronous retraction, the second slide rail 11 can have a shorter travel, occupying less space and achieving a more rational structure.

[0027] Furthermore, a first cylinder 71 and a second cylinder 72 are provided on the frame 101. The first cylinder 71 is used to drive the conveyor platform 1, and the second cylinder 72 is used to drive the push-button rod 4. The first cylinder 71 and the second cylinder 72 are only one option of this embodiment. In actual use, other actuators such as linear motors can be used as long as they can achieve the telescopic movement of the conveyor platform 1 and the push-button rod 4.

[0028] Furthermore, a buckle feeding mechanism is provided on one side of the frame 101, and the discharge port of the buckle feeding mechanism is adapted to the feeding position of the receiving channel 2. Figure 1-2 The upper buckle feeding mechanism can be a vibration plate feeding device, which conveys the upper buckle by mechanical vibration; the upper buckle enters from the feeding position of the receiving channel 2 and moves to the discharging position of the receiving channel 2, refer to Figure 3 , the buckle is pushed into the buckle seat 3 by the buckle rod 4 at the discharge position, and the buckle rod 4 can block the subsequent buckle. Figure 4-5, the conveyor platform 1 is pushed out again, and the buckle seat 3 is moved to the bottom of the punch rod 15. The end of the punch rod 15 has a slot for clamping the buckle. When the punch rod 15 is pressed down, the buckle can be received through the slot. The punch rod 15 rises, and then the conveyor platform 1 and the buckle pushing rod 4 are retracted synchronously. Then the punch rod 15 can be pressed downward to combine the buckle and the buckle.

[0029] Further, refer to Figure 5 A push buckle part 9 is provided at the front end of the push buckle rod 4, and the push buckle part 9 includes an upper stop part 901 and an accommodating cavity 902. The accommodating cavity 902 is adapted to the upper buckle, and is preferably provided with an arc structure or a V-shaped structure to prevent the button from tilting during the pushing process. The upper stop part 901 rests against the upper end surface of the upper buckle, and through the upper limit, prevents the upper buckle from flipping upward during the pushing process; thereby, the stable pushing of the upper buckle is guaranteed by the setting of the push buckle part 9.

[0030] Furthermore, a spring telescopic mechanism 10 is provided between the buckle seat 3 and the conveyor platform 1. Since the punch 15 requires a certain amount of pressure to allow the buckle 13 to enter the slot of the punch 15, the spring telescopic mechanism 10 is provided to allow the buckle seat 3 to have a certain amount of vertical telescopic space to prevent damage caused by rigid collision. At the same time, the spring can give the buckle seat 3 an upward force to help the buckle 13 get stuck in the slot.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
