Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to a detachable fabric guide device for a fabric splicing machine. Background Technology

[0002] On the sewing table of the sewing machine head of the fabric receiving machine, there is a fabric guide plate; the function of the fabric guide plate is to guide the fabric sheet during the movement of the sewing machine head.

[0003] Because the sewing table surface of a sewing machine head is smooth, it is not easy to fix the guide plate. Welding is often used to fix the guide plate to the sewing table. However, when using welding to fix the guide plate, if the sewing machine head malfunctions and needs to be replaced, the welded guide plate cannot be removed from the old sewing machine head and installed on the new one. A new guide plate must be welded onto the sewing table of the new sewing machine head, which is time-consuming and labor-intensive.

[0004] Designing a structure that allows for easy assembly and disassembly of the guide plate on the sewing machine head is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a detachable fabric guide device for a fabric splicing machine that allows for easy assembly and disassembly of the fabric guide plate on the sewing machine head.

[0006] To solve the above-mentioned technical problems, this utility model provides a detachable fabric guide device for a fabric splicing machine, which is installed on the sewing table of the sewing machine head; the sewing table is provided with a folded edge; the detachable fabric guide device includes: a fabric guide plate and a clamping block;

[0007] The guide plate includes a plate body and a plate connecting part connected to each other; the plate connecting part and the clamping block are detachably connected by a connector, and a groove is formed between the plate connecting part and the clamping block for the folded edge to be inserted, and the plate connecting part and the clamping block can clamp the folded edge.

[0008] Preferably, the clamping block includes a bottom connecting block and an upper clamping block disposed on the upper surface of the bottom connecting block. The bottom connecting block and the plate connecting part are connected by a connector, and the groove is formed between the upper clamping block and the plate connecting part.

[0009] Furthermore, the bottom connecting block is provided with a block threaded hole, the plate connecting part is provided with a plate through hole, and the connecting member is a screw; the screw body passes through the plate through hole and the block threaded hole in sequence, and the screw head presses against the plate connecting part.

[0010] Furthermore, the width of the groove is 0.2 mm to 0.4 mm larger than the width of the folded edge.

[0011] Preferably, the top surface of the guide plate body is a horizontally arranged plane, the side of the guide plate body where the fabric is fed is called the guide side, and the angle between the guide side and the moving direction of the sewing machine head is in the range of 15° to 25°.

[0012] As described above, the detachable fabric guide device for a fabric splicing machine of this invention has the following beneficial effects:

[0013] In this detachable fabric guide device for a fabric splicing machine, the plate connecting part and the clamping block are connected by a connector. After the folded edge is inserted into the groove formed between the plate connecting part and the clamping block, the connector applies a squeezing force to the fabric guide plate to fix it. The plate connecting part and the clamping block hold the folded edge. Since the connector can be detached, the fabric guide plate and the clamping block can be detached at the same time when the sewing machine head is replaced. Attached Figure Description

[0042] Example 1

[0043] like Figures 1 to 7 As shown, the detachable fabric guide device for the fabric receiving machine in this embodiment is installed on the sewing table 11 of the sewing machine head 10; the sewing table 11 is provided with a folded edge portion 12; the detachable fabric guide device includes: a fabric guide plate 100 and a clamping block 200.

[0044] The guide plate 100 includes a plate body 110 and a plate connecting part 120 connected to each other; the plate connecting part 120 and the clamping block 200 are detachably connected by a connector 300, and a groove 400 for inserting the folded edge part 12 is formed between the plate connecting part 120 and the clamping block 200, and the plate connecting part 120 and the clamping block 200 can clamp the folded edge part 12.

[0045] In this detachable fabric guide device for a fabric splicing machine, the plate connecting part 120 and the clamping block 200 are connected by a connector 300. After the folded edge 12 is inserted into the groove 400 formed between the plate connecting part 120 and the clamping block 200, the connector 300 applies a pressing force to the fabric guide plate 100 to fix the fabric guide plate 100. The plate connecting part 120 and the clamping block 200 hold the folded edge 12. Since the connector 300 can be detached, the fabric guide plate 100 and the clamping block 200 can be detached at the same time when the sewing machine head 10 is replaced, eliminating the welding step.

[0046] The clamping block 200 includes a bottom connecting block 210 and an upper clamping block 220 disposed on the upper surface of the bottom connecting block 210. The bottom connecting block 210 and the plate connecting part 120 are connected by a connector 300, and a groove 400 is formed between the upper clamping block 220 and the plate connecting part 120. The clamping block 200 has a simple structure, which can stably connect with the guide plate 100 and clamp the folded edge part 12 with the guide plate 100.

[0047] The bottom connecting block 210 has a block threaded hole 211, and the plate connecting part 120 has a plate through hole 121. The connector 300 is a screw; the screw body 310 passes through the plate through hole 121 and the block threaded hole 211 in sequence, and the screw head 320 presses against the plate connecting part 120. The guide plate 100 is connected to the clamping block 200 by screws. After the folded edge 12 is inserted into the groove 400 formed between the plate connecting part 120 and the clamping block 200, the screw is tightened. The tightening force of the screw creates an interference fit, and the compressive force fixes the guide plate 100.

[0048] If the groove 400 is too wide, the pressure applied by the guide plate 100 to the folded edge 12 will be insufficient; if the groove 400 is too narrow, the pressure applied by the guide plate 100 to the folded edge 12 will cause excessive twisting, making it easy to fall off. The width W1 of the groove 400 is 0.2 mm to 0.4 mm larger than the width W2 of the folded edge 12, which allows the groove 400 to stably hold the folded edge 12. In this embodiment, the width of the groove 400 is 0.3 mm larger than the width of the folded edge 12.

[0049] The top surface of the plate body 110 of the guide plate 100 is a horizontally arranged plane. The side of the plate body 110 of the guide plate 100 that guides the fabric is called the guide side 111. The angle C between the guide side 111 of the guide plate 100 and the moving direction of the sewing machine head 10 ranges from 15° to 25°. The guide side 111 of the plate body 110 facilitates the gradual transition of the fabric from a draped state to a flat state before it enters the presser foot for sewing. In this embodiment, the angle C between the guide side 111 of the guide plate 100 and the moving direction of the sewing machine head 10 ranges from 20°. The angle C between the guide side 111 of the guide plate 100 and the moving direction of the sewing machine head 10 is... Figure 6 The direction of the middle arrow B.

[0050] In summary, this embodiment effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0051] The above embodiments are merely illustrative of the principles and effects of this embodiment and are not intended to limit this embodiment. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this embodiment. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this embodiment should still be covered by the claims of this embodiment.
