Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a thread cutting head and a thread cutting machine for cutting thread ends. Background Technology

[0002] A thread trimming machine is a device that can cut and remove thread ends. It is widely used in the production of sewn products such as clothing and bags.

[0003] The wire cutting machine includes a connected wire cutting head and an air extraction and dust collection device. The wire cutting head has a connected cutting chamber and a suction channel. The air extraction and dust collection device works to draw the cut wire ends into the cutting chamber through the suction channel. To address the problem of air leakage in the suction channel of traditional wire cutting head housings (the housing is a split structure, with the suction channel formed by two split housing parts), the inventors designed a housing with a one-piece suction channel. However, further testing revealed that the sidewalls of the suction channel in this housing have burrs that are difficult to process (caused by demolding). Therefore, these burrs easily snag and accumulate, blocking the suction channel. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a thread cutter head for trimming thread ends.

[0005] This utility model also proposes a wire cutting machine having a wire cutting blade for trimming thread ends.

[0006] A thread cutter head for trimming thread ends according to a first aspect embodiment of the present invention includes a housing, a cover, a cutter head assembly, and a drive assembly. The housing has a cutting cavity, a receiving cavity, an integrally formed suction channel, and an integrally formed processing window. The cutting cavity and the processing window are both connected to the suction channel. The housing has an opening connecting the cutting cavity and the receiving cavity, and an inlet connecting the cutting cavity and the outside. The cover is disposed on the housing to cover and close the processing window. The cutter head assembly is disposed in the cutting cavity. The drive assembly is disposed in the receiving cavity. The output end of the drive assembly passes through the opening and is connected to the cutter head assembly in the cutting cavity. The drive assembly can drive the cutter head assembly to cut the thread ends entering the cutting cavity from the inlet. The housing is used to connect to an external air extraction and dust collection device, which can extract air to move the cut thread ends entering the cutting cavity through the suction channel.

[0007] A thread-cutting blade for trimming thread ends according to an embodiment of the present invention has at least the following beneficial effects:

[0008] With the above structure, on the one hand, the connection structure design of the shell and the cover of this application (i.e., the shell is provided with a connected, integrally formed suction channel and processing window, and the cover is provided on the shell to cover and seal the processing window) is easier to ensure the sealing of the suction channel by applying adhesive compared to the shell design of the traditional wire cutter head (half-spliced ​​structure). Therefore, the probability of air leakage in the suction channel is lower. On the other hand, the setting of the processing window makes it convenient for workers to handle burrs on the side wall of the suction channel, thereby reducing the problem of burrs snagging on the wire ends and accumulating and blocking the suction channel.

[0009] According to some embodiments of the present invention, the housing includes an integrally formed handle portion and a curved portion connected together. A portion of the suction channel is located in the handle portion and another portion is located in the curved portion. The processing window is located at the connection between the handle portion and the curved portion. The handle portion is used to connect with an external air extraction and dust collection device.

[0010] According to some embodiments of the present invention, the shell is provided with a first hole, the cover is provided with a second hole, and fasteners are inserted through the first hole and the second hole.

[0011] According to some embodiments of the present invention, one of the shell and the cover is provided with a positioning block and the other is provided with a positioning groove. The positioning block is inserted into the positioning groove so that the first hole and the second hole are correspondingly set.

[0012] According to some embodiments of the present invention, one of the shell and the cover is provided with an annular protrusion and the other is provided with an annular groove. The protrusion or the groove provided on the shell surrounds the processing window, and the protrusion is inserted into the groove.

[0013] According to some embodiments of the present invention, a sealing adhesive layer is provided in the gap between the cover and the shell.

[0014] The wire cutting machine according to a second aspect of the present invention includes a wire cutting head for cutting off wire ends as described above.

[0015] The wire cutting machine according to the present invention has at least the following beneficial effects: With the above structure and the setting of the processing window, it is convenient for workers to handle burrs located on the side wall of the suction channel, thereby reducing the problem of burrs snagging the wire ends and accumulating and blocking the suction channel.
