Technical Field

[0001] This utility model relates to a component for an embroidery machine, and more particularly to a thread clamp device for an embroidery machine. Background Technology

[0002] Currently, in the embroidery machine industry, with the increasing requirements for product performance and the increase in embroidery output, the existing thread clips have structural problems that make the assembly of thread clips and the replacement of accessories very troublesome, and cannot reduce production costs. How to reduce the overall cost of thread clips and simplify assembly is a goal of improving the technology of thread clips in the embroidery industry. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a face thread clamp device for embroidery machines, which addresses the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following measures:

[0005] A thread clamping device for an embroidery machine includes a thread clamping seat and a brush strip with a base plate arranged along the length of the thread clamping seat. Two thread clamping seats are arranged opposite each other. The two ends of the thread clamping seats are provided with connectors and mounting feet. The brush strip with the base plate is fixed to the inner side of the two thread clamping seats opposite each other. The two ends of the two thread clamping seats are fixedly connected by the connectors through an interference fit. Among the two thread clamping seats, the two ends of the inner thread clamping seat are fixed to the outer side of the thread clamping seat by screws.

[0006] The inner side of the wire clamp is provided with a T-shaped opening groove along the length direction. The bottom plate of the brush strip is slidably connected to the T-shaped opening groove. The upper and lower edges of the wire clamp are provided with chamfers and R-angles. The wire clamp is made of aluminum alloy profile.

[0007] The brush strip includes upright bristles and a base plate. The outer side of the base plate has multiple upright bristles arranged regularly or irregularly. The upright bristles are fixed to the base plate. The upright bristles and the base plate are made of plastic.

[0008] The connector is made of plastic and is interference-fitted to both ends of the T-shaped opening groove inside the wire clamp.

[0009] The mounting feet are provided with limiting protrusions, and the outer side of the wire clamp is provided with limiting holes corresponding to the limiting protrusions. When the mounting feet are fixed to the wire clamp by screws, the limiting protrusions fall into the limiting holes to achieve limiting. Both the wire clamp and the mounting feet are provided with mounting thread holes for screw thread connection.

[0010] The limiting hole is a blind hole, and the mounting threaded hole is a threaded through hole that extends from both sides;

[0011] A washer is fitted onto the screw;

[0012] The connector has raised ribs on both sides for interference fit with the T-shaped opening groove, and a groove on the inner side of the connector for screws to pass through.

[0013] An embroidery machine is provided with the embroidery machine thread clamp device described in any one of the above claims.

[0014] The beneficial effects of this utility model are: practicality, novel structure, and use of a brush strip with a base. By setting a T-shaped opening groove on the wire clamp, the installation and replacement of the brush strip are facilitated. By adding chamfers on both sides of the wire clamp, the wire hook knife can move in and out more smoothly. By using prefabricated plastic connectors at both ends, the assembly process is simplified, the assembly efficiency is improved, and the assembly cost is reduced. Attached Figure Description

[0021] A thread clamping device for an embroidery machine includes a thread clamping base 1 and a brush strip 2 with a base plate 22 arranged along the length of the thread clamping base 1. Two thread clamping bases 1 are arranged opposite each other. Each thread clamping base 1 has a connector 3 and mounting feet 4 at both ends. The brush strip 2 with the base plate 22 is fixed to the inner side of the two opposing thread clamping bases 1. The two ends of the two thread clamping bases 1 are fixedly connected by the connector 3 through an interference fit. The mounting feet 4 are fixed to the outer surface of the inner thread clamping base 1 by screws 5. The shape and size of the mounting feet 4 can be changed according to the installation angle and position. The thread clamping device for the embroidery machine is assembled and secured with two screws 5, greatly improving assembly efficiency and reducing production costs.

[0022] The inner side of the wire clamp 1 is provided with a T-shaped opening groove 11 along the length direction. The bottom plate 22 of the brush strip 2 is slidably connected to the T-shaped opening groove 11. The upper and lower edges of the wire clamp 1 are provided with bevel angles 12 and R angles 13 to facilitate the entry and exit of the wire hook knife. The wire clamp 1 is made of aluminum alloy profile, but of course, it also includes, but is not limited to, various metal and non-metal materials.

[0023] The brush strip 2 includes upright bristles 21 and a base plate 22. The outer side of the base plate 22 is provided with multiple upright bristles 21 arranged regularly or irregularly. The upright bristles 21 are fixed on the base plate 22. The upright bristles 21 and the base plate 22 are made of plastic material. The upright bristles 21 have appropriate softness, and of course, they include but are not limited to various plastic and rubber materials.

[0024] The connector 3 is made of plastic and is interference-fitted to both ends of the T-shaped slot 11 inside the wire clamp 1. Of course, it can also be made of various metals and non-metals, and its shape and connection method can be changed according to actual needs, including but not limited to the shapes shown in the accompanying drawings.

[0025] The mounting foot 4 is provided with a limiting protrusion 401, and the outer side of the wire clamp 1 is provided with a limiting hole 101 corresponding to the limiting protrusion 401. When the mounting foot 4 is fixed to the wire clamp 1 by the screw 5, the limiting protrusion 401 falls into the limiting hole 101 to achieve limiting, which facilitates fixing and prevents rotation. Of course, it is not limited to the shape shown in the picture. The shape and limiting connection method can be changed according to actual needs. Both the wire clamp 1 and the mounting foot 4 are provided with mounting thread holes 102 for screw 5 threaded connection.

[0026] The limiting hole 101 is a blind hole, and the mounting threaded hole 102 is a threaded through hole that extends through both sides.

[0027] A washer 6 is fitted onto the screw 5.

[0028] The connector 3 has protruding ribs 301 on both sides for interference fit with the T-shaped opening groove 11, and the inner side of the connector 3 has a groove 202 for the screw 5 to pass through.

[0029] As shown in the figure, the embroidery machine using the above-mentioned solution has a face thread clamp device, and the brush (brush strip 2) is easy to replace and can be used in both new and old machines.

[0030] The T-shaped opening slot 11 allows the brush strip 2 to be inserted and holds the bottom plate 22 of the brush strip 2 in place, making it easy to remove and replace the brush strip 2 and improving production and assembly efficiency. Connectors 3 are provided at both ends to prevent the brush strip 2 from slipping out.

[0031] An embroidery machine is provided with the embroidery machine thread clamp device described in any one of the above claims.
