Description

Technical Field

[0001] This utility model relates to the field of button attaching machine technology, and in particular to a button attaching machine with a clamping mechanism. Background Technology

[0002] A button-attaching machine is a specialized automatic sewing machine used for sewing buttons with regular shapes and for "stitching" or "drip" sewing processes, such as attaching labels, tags, and caps. It most commonly sews round, two- or four-hole (also known as flat buttons) buttons. By replacing various specialized button-attaching machine accessories, one machine can sew various types of buttons, including handle buttons, metal buttons, snap buttons, loop buttons, and top buttons. Users can request specialized accessories from the equipment supplier as needed.

[0003] In the prior art, Chinese patent application number 202223244971.X discloses a button clamping mechanism for a button sewing machine, including a cover plate for mounting on the machine. The bottom end of the cover plate is rotatably connected to two clamping heads for clamping buttons via two shafts. The tail end of each clamping head is provided with an adjusting component for adjusting its tension. The bottom end of the cover plate is provided with an abutting component located between the two clamping heads for button positioning. This button clamping mechanism uses the adjusting component to apply outward pressure to the end of the clamping head, causing the head of the clamping head to open inward. The button needs to be placed in the grooves of the two clamping heads for clamping. The abutting component blocks the button and is adjusted for different button sizes, ensuring that the button contacts the abutting component and is clamped on the clamping head. This ensures accurate button positioning and is suitable for most button sizes.

[0004] However, in the above-mentioned technical solutions, the clamping head holds the button by the elastic force of the spring, and the abutting head is driven by gears and racks. Here, the spring has elastic rebound force, and the meshing of the gears and racks does not have positioning, which makes the clamping of the button by the clamping head and the abutting head unstable. The button is very easy to loosen during the button-attaching process, which cannot meet the usage requirements. Therefore, this application proposes a button-attaching machine with a clamping mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies where the pliers clamp the button by the spring force, and the abutting head is driven by gears and racks. Here, the spring has elastic rebound force, and the meshing of the gears and racks does not have positioning, resulting in unstable clamping of the button by the pliers and abutting head. The button is very easy to loosen during the button-attaching process, which fails to meet the usage requirements. Therefore, this invention proposes a button-attaching machine with a clamping mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A button-attaching machine with a clamping mechanism includes a housing, the clamping mechanism further comprising:

Two clamp heads are slidably sleeved on the stabilizer bar. The front end of the transmission rod is rotatably connected to the rear end of the corresponding clamp head. The front ends of the two clamp heads penetrate the front inner wall of the housing and extend to the outside of the housing. Two springs are sleeved on the stabilizer bar. The ends of the two springs that are close to each other are fixedly installed on the sides of the two clamp heads that are far apart from each other. The ends of the two springs that are far apart from each other are fixedly installed on the left and right inner walls of the housing, respectively.

[0012] Two pads are provided, and the pads are fixedly installed on the bottom of the corresponding pliers heads;

[0013] An abutting component is disposed on the front side of the housing and is used to abut and secure the button.

[0014] As a preferred embodiment of this utility model, a fixing plate is fixedly installed on the bottom inner wall of the box, and the front end of the screw is rotatably connected to the fixing plate.

[0015] As a preferred embodiment of this utility model, two telescopic rods are fixedly installed on the rear inner wall of the box, and the front ends of the two telescopic rods are fixedly installed on the rear side of the movable plate.

[0016] As a preferred embodiment of this utility model, two sliding holes are provided on the inner wall of the front side of the box, and the front end of the pliers head passes through the corresponding sliding hole and is slidably connected to the inner wall of the sliding hole.

[0017] In a preferred embodiment of this utility model, the abutting assembly includes an electric push rod and an abutting head. The electric push rod is fixedly installed on the front side of the housing, and the abutting head is fixedly installed on the output shaft of the electric push rod.

[0019] Beneficial effects:

[0020] 1. By placing the button on top of the two pads, and then rotating the screw and engaging the screw with the moving plate through the threaded connection, the two transmission rods can be driven to rotate and the two clamps can be driven to move closer to each other. At this time, the spring is stretched, and the two clamps can clamp and fix the button on the two pads.

[0021] 2. By activating the electric push rod, the contact head can be driven to move back and forth, thereby enabling automated button clamping operation according to the size of the button;

[0022] This invention achieves rapid adjustment of the distance between the two clamping heads through a simple structure, and also enables rapid adjustment of the distance between the contact head and the button. The adjustment process is convenient and quick, and the stability after adjustment is high, ensuring stable clamping and fixing of the button, which facilitates subsequent button sewing processing and has strong practicality.
