AI Technical Summary
When the existing roller cart pulls the bottom line, the pulling distance is too small, resulting in insufficient tension provided by the blade on the bottom line, which can easily cause the seams to be disconnected.
A Ronar car knife is designed. The lines of the pull line include connecting blocks, pull -line blocks and extension blocks. Pulling blocks and connecting blocks form a line groove. The length of the expansion of the sliding groove is expanded to increase the tension of the bottom line.
Through the design of the extension block, the stretching space of the bottom line is added, thereby improving the tension tension of the bottom line, reducing the occurrence of the stitching line, and improving the stability of the sewing process.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewing machines, in particular to a roller-type moving knife. Background Art
[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. A roller sewing machine is a sewing machine that is mainly used for sewing and decoration of textiles. The moving knife is an important part of the roller sewing machine, which is responsible for feeding the bottom thread into the fixed knife for sewing.
[0003] At present, when the movable knife of the existing roller lathe pulls the bottom line, the pulling distance of the bottom line is too small, resulting in insufficient tension provided by the movable knife to the bottom line, which easily causes the seam to come off. Summary of the invention
[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a roller turning knife to solve the above-mentioned problems.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller lathe movable knife, including a movable knife head, the movable knife head includes a connecting end and a wire pulling end, the connecting end is used to connect to an external driving device, the wire pulling end is used to pull the bottom line, the wire pulling end includes a connecting block and a wire pulling block, the first end of the connecting block is connected to the connecting end, the second end of the connecting block is connected to the wire pulling block, a wire pulling groove is formed between the wire pulling block and the connecting block, and an extension block is provided at the bottom of the wire pulling groove.
[0006] Preferably, the extension block and the wire pulling block are integrally formed.
[0007] Preferably, the extension block and the wire pulling block are integrally formed.
[0008] Preferably, the thickening length of the extension block is 0.5 mm to 3 mm.
[0009] The beneficial technical effect of the utility model is that the bottom line in the sewing process is pulled by the wire pulling groove formed by the wire pulling block and the connecting end, thereby completing the wire feeding process of the bottom line; when the wire pulling groove feeds the bottom line, the extension section integrally arranged with the wire pulling block and the pulling length of the bottom line are expanded, so that the displacement length of the bottom line driven by the wire pulling block is increased, thereby increasing the tensile tension of the bottom line, preventing the bottom line from being derailed due to the excessive tensile force on the bottom line, thereby improving the stability of the sewing process and reducing the number of times the bottom line is derailed. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is an overall schematic diagram of the utility model;
[0011] Figure 2 It is a schematic diagram of the wire pulling end structure of the utility model.
[0012] Figure numerals: 1, moving cutter head; 2, connecting end; 3, wire pulling end; 31, connecting block; 32, wire pulling block; 33, wire pulling groove; 34, extension block. Implementation
[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0014] Example 1, reference Figure 1-2 As shown, a roller lathe movable knife includes a movable knife head 1, and the movable knife head 1 includes a connecting end 2 and a wire pulling end 3. The connecting end 2 is used to connect with an external driving device, and the wire pulling end 3 is used to pull the bottom line.
[0015] The wire pulling end 3 includes a connecting block 31 and a wire pulling block 32. The first end of the connecting block 31 is connected to the connecting end 2, and the second end of the connecting block 31 is connected to the wire pulling block 32. A wire pulling groove 33 is formed between the wire pulling block 32 and the connecting block 31.
[0016] An extension block 34 is provided at the bottom of the wire drawing groove 33 . The extension block 34 is integrally formed with the wire drawing block 32 , and the thickness increase length of the extension block 34 is 0.5 mm to 3 mm.
[0017] In this embodiment, when in use, the bottom line in the sewing process is pulled by the wire pulling groove 33 formed by the wire pulling block 32 and the connecting end 2, thereby completing the wire feeding process of the bottom line. When the wire pulling groove 33 feeds the bottom line, the extension block 34 integrally arranged with the wire pulling groove 33 is expanded with the pulling length of the bottom line, so that the displacement length of the bottom line driven by the wire pulling groove 33 is increased, thereby increasing the tensile tension on the bottom line, preventing the bottom line from being derailed due to the excessive tensile force on the bottom line, thereby improving the stability of the sewing process and reducing the number of times the bottom line is derailed.
[0018] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
