Description

Technical Field

[0001] This utility model relates to the technical field of button attaching machines, specifically a locking and lubrication mechanism below the needle plate in a button attaching machine. Background Technology

[0002] A button sewing machine is an industrial sewing device specifically designed for automatically sewing buttons, labels, tags, and other products. It features stability and diverse operating functions and is widely used in the garment processing industry. The needle plate of the button sewing machine is the core component, mainly used to fix the buttons and ensure the stability of the stitches during sewing.

[0003] However, the locking assembly under the needle plate in a typical button-attaching machine lacks an automatic lubrication mechanism. This means that the friction is relatively high when the movable connecting plate slides between the fixed connecting plate and the movable connecting plate. This results in severe wear during long-term use and affects the service life.

[0004] To address this issue, we propose a locking and lubrication mechanism located below the needle plate in a button-attaching machine. Summary of the Invention

The movable connecting plate is fitted to the upper end of the connecting base plate, and the driving device drives the movable connecting plate to form a sliding structure in the lubricated connecting cavity.

[0015] By adopting the above technical solution, the movable connecting plate is connected to the drive device on the button attaching machine. The movable connecting plate is fitted to the upper end of the connecting base plate. At the same time, the drive device drives the movable connecting plate to form a sliding structure in the lubricated connecting cavity, thereby improving the stability of the movable connecting plate in moving the thread cutting connecting plate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 The present invention provides the following technical solution:

[0032] To address the problem in existing button-attaching machines where the locking assembly below the needle plate lacks an automatic lubrication mechanism, resulting in significant friction when the movable connecting plate 8 slides within the fixed connecting plate 2, leading to severe wear and reduced lifespan over long-term use, this solution provides a locking lubrication mechanism below the needle plate. This mechanism comprises a button-attaching machine needle plate 1, a fixed connecting plate 2, a connecting base plate 4, a movable connecting plate 8, and a thread-cutting connecting plate 9 fixed to the lower end of the movable connecting plate 8. A lower lubrication channel is located in the center of the connecting base plate 4, while upper lubrication channels are located on the left and right sides of the movable connecting plate 8. The upper lubrication channels are located above and communicate with the lower lubrication channels, delivering lubricating oil to the connection points of the movable connecting plate 8, the fixed connecting plate 2, and the connecting base plate 4.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, the button plate 1 of the button sewing machine is located below the button sewing machine needle, and a fixed connecting plate 2 is fixed to the lower end of the button plate 1. A lubrication connecting cavity 3 is opened in the middle of the fixed connecting plate 2. At the same time, the movable connecting plate 8 is connected to the drive device on the button sewing machine. The movable connecting plate 8 is fitted to the upper end of the connecting base plate 4. At the same time, the front and rear ends of the fixed connecting plate 2 and the connecting base plate 4 are provided with corresponding mounting screw holes 5. The fixed connecting plate 2 and the connecting base plate 4 are limited by bolts screwed into the mounting screw holes 5. At the same time, the drive device drives the movable connecting plate 8 to form a sliding structure in the lubrication connecting cavity 3. The upper lubrication channel is composed of the second lubrication groove 10 opened on the left and right sides of the lower end of the movable connecting plate 8, the second lubrication hole 11 at the upper end of the second lubrication groove 10, and the lubricating oil delivery groove 12 at the upper end of the second lubrication hole 11. The lower lubrication channel is composed of the first lubrication groove 6 opened in the middle of the connecting base plate 4 and the first lubrication hole 7 set on the front and rear sides of the first lubrication groove 6.

[0034] Combination Figure 4 and Figure 5 As shown, the first lubrication groove 6 is located in the middle of the connecting base plate 4, and is connected to a lubricating oil reservoir mounted on the button-attaching machine below. The reservoir contains a micro pump, which is controlled to start and stop via a relay. The reservoir is connected to the first lubrication groove 6 via an oil pipe (not shown in the figure). The movable connecting plate 8 slides left and right in the lubrication connecting cavity 3 via an external drive device. The micro pump can be controlled to start and stop via a relay at regular intervals, thereby drawing lubricating oil from the reservoir and delivering it to the first lubrication groove 6 via the oil pipe. The lubricating oil is also delivered upwards through the first lubrication hole 7. Connected to the upper lubrication channel, lubricating oil enters the upper lubrication channel through the first lubrication hole 7, that is, the lubricating oil enters the second lubrication groove 10, and is transported to the lubricating oil conveying groove 12 through the second lubrication hole 11 to diffuse outward, delivering the lubricating oil outward to the area between the movable connecting plate 8, the fixed connecting plate 2 and the connecting base plate 4, thereby enabling sufficient lubrication between the movable connecting plate 8, the fixed connecting plate 2 and the connecting base plate 4, reducing the frictional force of the movable connecting plate 8 sliding in the lubrication connecting cavity 3, thus ensuring smooth movement during the wire cutting process, reducing wear, and extending the service life of the entire moving part.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
