Description

Technical Field

[0001] This utility model relates to the field of chain sewing machine technology, specifically a twelve-needle needle bar holder for a multi-needle chain sewing machine. Background Technology

[0002] A chain stitch machine is an industrial sewing device that completes sewing by forming a chain stitch with needle and thread. The stitch consists of a bobbin thread and a top thread interwoven into a loop, which has strong tensile strength and good elasticity. It is suitable for stretchy materials such as knitted fabrics and leather. It does not require frequent bobbin thread replacement during operation, is highly efficient, and is widely used in the clothing, bag and other manufacturing industries. It is especially suitable for scenarios that require strong seams.

[0003] The 12-needle needle holder for multi-needle chain stitch machines is an accessory that can be fitted with 12 needles to form 12 chain stitches simultaneously. It is suitable for scenarios that require multi-thread reinforcement or decorative sewing, such as waistbands and skirts, improving sewing efficiency and stitch consistency.

[0004] Existing needle bar holders have the following problems: it is usually difficult to control the amount of liquid lubricating grease injected. When the amount of grease is small, the grease is easily unevenly distributed in the gap; when the amount of grease is large, it is easy to overflow from the end of the gap and contaminate the sewing material. In addition, the straight oil injection hole makes it difficult for the grease to flow downward. To address the above problems, a twelve-needle needle bar holder for multi-needle chain sewing machines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a twelve-needle needle bar holder for a multi-needle chain sewing machine, which solves the problem in the prior art that it is usually difficult to control the amount of injected liquid lubricating grease.

[0018] As a further description of the above technical solution: the bottom of the placement seat is fixedly connected to an installation component, the installation component is threadedly connected to the bottom of the oil bottle, and the installation component is fixedly connected to the top of the hose.

[0019] By adopting the above technical solution, the oil bottle and hose are connected by an installation component to form a passage.

[0020] As a further description of the above technical solution: both sides of the front top of the needle bar frame are fixedly connected to mounting bases, and the mounting bases have threaded holes in the middle.

[0021] By adopting the above technical solution, the needle bar frame is installed using a mounting base.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. The present invention provides a twelve-needle needle bar holder for a multi-needle chain sewing machine. The lubricating oil is absorbed by the coating component. The capillary force between the micropores of the coating component will adsorb the oil in the pores to achieve oil storage. When the needle bar moves, the slight friction with the material surface will break the surface tension of the local oil, causing the oil to slowly seep out along the pore channel to the contact interface for coating.

[0024] 2. The present invention provides a twelve-needle needle bar holder for a multi-needle chain sewing machine. By installing the oil bottle on the mounting part, and then rotating the placement seat to invert the oil bottle, a spring pops out the limiting part, and the limiting part is inserted into the needle bar holder to limit the rotation seat, so that the oil bottle cannot rotate, thereby fixing the oil bottle.

A connecting rod 5 is fixedly connected to the right side of the placement seat 6. A fixing component is set at the top left side of the needle bar holder 1.

[0032] Combination Figure 3 The fixing component includes a rotating seat 12, which passes through and is rotatably connected to the top left side of the needle bar frame 1. The left side of the rotating seat 12 is fixedly connected to the right end of the connecting rod 5. The rotating seat 12 drives the connecting rod 5 to rotate. A limiting member 13 passes through and is slidably connected in the middle of the rotating seat 12. The limiting member 13 is slidably connected to the middle of the needle bar frame 1. A spring 14 passes through and is provided in the middle of the rotating seat 12. One end of the spring 14 is fixedly connected to the outer wall of the limiting member 13. The spring 14 pops out the limiting member 13, so that the limiting member 13 is inserted into the needle bar frame 1 for limiting.

[0033] Combination Figure 1 and 3 A disassembly rod 16 is slidably connected through the top left side of the needle bar holder 1, and the disassembly rod 16 cooperates with the limiting member 13. Pressing the disassembly rod 16 presses the limiting member 13 into the rotating seat 12, canceling the limiting and allowing the rotating seat 12 to rotate. A second spring 17 is sleeved through the middle of the disassembly rod 16, and one end of the second spring 17 is fixedly connected to the inner wall of the needle bar holder 1. The second spring 17 drives the disassembly rod 16 to reset. An inner liner 15 is fixedly connected through the middle of the needle bar holder 1.

The needle bar frame 1 is installed through the mounting seat 2.

[0034] Working principle: By installing the oil bottle 4 on the mounting part 7, and then rotating the placement seat 6, the oil bottle 4 is inverted. At this time, the spring 14 pops out the limiting part 13, and the limiting part 13 inserts into the needle bar holder 1 to limit the rotating seat 12, so that the oil bottle 4 cannot rotate, thus fixing the oil bottle 4. The lubricating oil in the oil bottle 4 flows into the pipe 9 in the needle bar holder 1 through the hose 8. The lubricating oil is absorbed by the applicator 11. The capillary force between the micropores of the applicator 11 will adsorb the grease in the pores to achieve oil storage. When the needle bar moves, the slight friction with the material surface will break the surface tension of the local grease, causing the grease to slowly seep out along the pore channels to the contact interface for application.
