Problems solved by technology

On the one hand, the conventional thread-passing spring 3a is easy to wear and break, and the broken spring phenomenon is serious. When replacing the thread-passing spring 3a, it is necessary to first disassemble the thread-passing wheel 1a from the wheel seat 2a, and then replace it with a new thread-passing spring 3a. The thread passing wheel 1a can only be put into a new round of use before it can be put into a new round of use. The installation process is relatively cumbersome, and the thread passing spring 3a is replaced frequently, which increases the cost of the alarm components of the embroidery machine. Frequent loading and unloading of the thread passing wheel 1a will also cause the thread passing wheel to The mechanical wear of 1a affects the precision of the overall alarm device; on the other hand, during the high-speed operation of the embroidery thread, the friction on the surface of the thread passing spring 3a is relatively large, which will cause certain damage to the embroidery thread itself, and the embroidery thread is easy to The occurrence of static electricity often causes false alarms or short circuits of the sensor. In severe cases, it will cause a short circuit of the circuit and burn out the entire alarm device. It is beneficial to safe production, and the electrostatic effect at the thread passing spring 3a makes the embroidery thread easily entangled on it, causing thread jamming, grinding, etc., and the embroidery thread is easy to run off

Embodiment 1

[0024] The embroidery alarm device of the present invention combines figure 2 , Including the thread passing wheel 1, the wheel seat 2 and the alarm component 5. The thread passing wheel 1 is installed on the wheel seat 2. The alarm component 5 includes a hook structure 51, a fixing structure 52 and a thread groove 53, as well as an alarm contact spring 3 and The sensing sheet 6 used in conjunction with the alarm contact spring 3, the hook structure 51 is divided into a hook portion 511 and a body 512. The gap between the hook portion 511 and the body 512 forms a wire slot 53; the fixing structure 52 is arranged on the body 512; The bottom end 32 of the contact spring is fixed under the wire passing wheel 1, and the upper end 31 of the alarm contact spring is matched and installed on the fixing structure 52 for fixing the alarm component 5. image 3 , The fixing structure 52 includes a groove 521 opened along the body 512 of the hook structure 51, a hanging spring buckle 522 arr...

Embodiment 2

[0027] The configuration and working principle of this embodiment are the same as that of the first embodiment. The difference is that the alarm component 5 includes a hook structure 51, a fixing structure 52, and a wire-passing groove 53. The hook structure 51 is divided into a hook 511 and a body 512. Figure 4 , The fixing structure 52 includes a groove 521, an anti-drop opening 523, and a hanging spring buckle 522 arranged in the groove 521. The fixing structure 52 is arranged on the side of the main body 512, and the groove 521 is perpendicular to the plane where the main body 512 and the hook 511 are located. The upper end 31 of the spring penetrates into the through groove 521 through the anti-drop opening 523, and is positioned by the hanging spring buckle 522. The groove 521 is a through groove, and the alarm component 5 is made of glass as a whole.

[0028] The use of different structures of the alarm component 5 can realize different installation methods, so that the ho...

Abstract

The invention relates to an alarm device for an embroidery machine, which belongs to the technical field of additional devices of an embroidery machine. The alarm device comprises a wire through wheel and an alarm part, wherein the wire through wheel is mounted on a wheel base; the alarm part is mounted on the wheel base, and is on the same side of the wire through wheel; the alarm part comprises a hook structure, a fixing structure and a wire through groove, as well as an alarm contact spring and a sensor sheet used in coordination with the alarm contact spring; the hook structure is divided into a hook part and a main body; the wire through groove is formed by the groove between the hook part and the main body; the fixing structure is arranged on the main body; and the bottom of the alarm contact spring is mounted below the wire through wheel, while the top end is mounted on the fixing structure in coordination, and is used for fixing the alarm part. The alarm device for the embroidery machine, provided by the invention, has the advantages of high alarm accuracy, static electricity resistance, long service life and the like, and can be applied to computer embroidery machines and normal embroidery machines.

Description

Technical field [0001] The invention relates to an alarm device for embroidery machines, belonging to the technical field of additional devices used with embroidery machines. Background technique [0002] In the process of embroidery or embroidery, computerized embroidery machines often have thread breakage and thread drop. If it is not found in time, thread leakage will appear on the fabric, which will affect the pattern and the beauty of the pattern, and it is also not conducive to the fabric. The improvement of quality indicators such as strength. Therefore, before the embroidery thread enters the loop, an alarm device is usually set, combined with figure 1 , Used for alarm and control of disconnection and disconnection. [0003] The conventional alarm device includes a thread passing wheel 1a and a thread passing spring 3a. The thread passing wheel 1a and the thread passing spring 3a are both installed on the wheel seat 2a. The thread passing spring 3a is located on the side o...
