Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a silk thread clamping device for embroidery machines. Background Art

[0002] With the development of textile industry, more and more textile equipments are becoming more perfect. Among them, embroidery machine is the most advanced embroidery machine in the contemporary era. It can realize the traditional hand embroidery with high speed and high efficiency, and can also realize the multi-level, multi-functional and unified requirements which cannot be achieved by hand embroidery.

[0003] The silk threads on the existing embroidery machines are generally rotated through the silk thread sleeve, so as to realize the feeding of the silk threads, so as to facilitate the embroidery machine to perform embroidery processing.

[0004] However, the above-mentioned silk thread may break during the feeding process, and the embroidery machine is not provided with a corresponding clamping device, which may easily cause the broken threads to be entangled together, resulting in an increase in the workload of finding the broken threads. For this reason, we propose a silk thread clamping device for an embroidery machine. Utility Model Content

[0005] The utility model aims to provide a silk thread clamping device for an embroidery machine. By setting a clamping mechanism, it is convenient to use a fixed roller to guide the silk thread in advance. By adjusting the cooperation of the component and the elastic component, the movable roller can be moved and cooperate with the fixed roller to produce a good clamping effect, so that the silk thread can be clamped and fixed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a thread clamping device for an embroidery machine, comprising a fixed frame, on which a clamping mechanism is provided, and the clamping mechanism comprises:

[0008] A connecting bracket, wherein the connecting bracket is arranged on one side of the movable drum;

[0009] An elastic component, wherein the elastic component is arranged between the connecting bracket and the movable roller;

[0010] The adjusting component is arranged in the middle of the connecting bracket, and the adjusting component is used to adjust the position of the connecting bracket.

[0011] Preferably, the elastic component includes grooves opened at both ends of the connecting bracket, a circular groove opened on one side of the groove, a limit frame arranged on one side of the middle part of the connecting bracket, a sliding rod fixedly connected to both sides of the limit frame, an extrusion spring sleeved on the outer surface of the sliding rod, a sliding sleeve sleeved on the end of the sliding rod, a pushing rod hinged to one side of the sliding sleeve, a locking sleeve threadedly connected to one end of the sliding rod and a guide rod inserted into the interior of the limit frame, and one end of the locking sleeve is inserted into the interior of the circular groove.

[0012] Preferably, the adjustment assembly includes a fixed sleeve fixedly connected to the outer surface of the fixed frame, an adjustment threaded rod rotatably arranged inside the fixed sleeve, an adjustment round block fixedly connected to one end of the adjustment threaded rod, a movable sheet threadedly connected to the outer surface of the adjustment threaded rod, and a movable sleeve fixedly connected to one side of the movable sheet, and one end of the movable sleeve is fixedly connected to the outer surface of the connecting bracket.

[0013] Preferably, the roller assembly is composed of a rotating column and an elastic sleeve fixedly connected to the outer side of the rotating column, and the elastic sleeve is made of sponge or rubber.

[0014] Preferably, a protrusion is fixedly connected to the inner side of the fixed frame, and the inner wall surface of the protrusion is rotatably connected to two ends of the fixed roller.

[0015] Preferably, one end of the guide rod is fixedly connected to a roller bracket, and the interior of the roller bracket is rotatably connected to both ends of the movable roller.

[0016] Technical effects and advantages of the utility model:

[0017] The silk thread is passed around the fixed roller, thereby achieving the guidance and tensioning of the silk thread. When the silk thread is broken, the elastic component and its connecting bracket are driven to move by the adjusting component, thereby driving the movable roller to move, so that the movable roller is continuously close to the silk thread, thereby clamping and fixing the silk thread. At the same time, the elastic component can make the movable roller and the fixed roller cooperate better to clamp and fix the silk thread, and the multiple clamping mechanisms set up can better clamp and fix different silk threads, thereby making it easy for users to find the broken silk thread without affecting the normal operation of other silk threads.
