[0043] Please refer to Figures 1-2 , this embodiment provides a material receiving mechanism, which is arranged at the material receiving end of the sewing machine frame and includes:

[0044] An adjusting component 1, which can move in a direction perpendicular to the material receiving end to approach or move away from the material receiving end;

[0045] The material receiving rod 2 is horizontally installed on the adjusting assembly 1 along a direction parallel to the material receiving end, and the vertical position of the material receiving rod 2 on the adjusting assembly 1 is adjustable;

[0046] The air blowing assembly is arranged at the material receiving end. The air blowing assembly is located below the fabric and is used to blow up the fabric to turn it over the material receiving rod 2.

[0047] It should be noted that when sewing the fabric, the fabric completed by sewing is moved by the drag cloth roller behind the sewing needle. Due to the certain elasticity of the fabric, when the drag cloth roller moves away from the sewing needle to move the fabric, the fabric will become longer, affecting the sewing effect. Therefore, in this embodiment, the material receiving end is designed to be inclined rather than right-angled. When the fabric falls on the material receiving end, the fabric naturally slides down under the action of gravity.

[0048] The working principle of the material receiving mechanism provided by the present utility model is as follows:

[0049] Before receiving the material, there is a spacing between the material receiving rod 2 and the material receiving end, and the material receiving end has an inclined surface. After the fabric is sewn, it slides down along the inclined surface and falls into the inner side (between the material receiving rod 2 and the material receiving end) of the material receiving rod 2 after passing through the air blowing assembly. When a part of the fabric (usually set to about half of the fabric) falls into the inner side of the material receiving rod 2, control the adjusting assembly 1 to move towards the direction close to the material receiving end and drive the material receiving rod 2 to move to press the fabric (this part of the fabric is pressed between the material receiving rod 2 and the material receiving end), and then drive the remaining part of the fabric to continue to move. Under the action of the air blowing assembly, the remaining fabric is blown up to turn it over the material receiving rod 2 and falls on the outer side of the material receiving rod 2, that is, the front and back two parts of the fabric respectively fall on the inner and outer sides of the material receiving rod 2. At this time, the fabric is placed on the material receiving rod 2.

[0050] Since the vertical position of the material receiving rod 2 on the adjusting assembly 1 is adjustable, the vertical height of the material receiving rod 2 can be adjusted according to the length of the fabric to collect fabrics of different lengths. For example, when receiving short-sized fabrics, the position of the material receiving rod 2 is relatively high, and when receiving long-sized fabrics, the position of the material receiving rod 2 is relatively low.

[0051] Preferably, as Figure 5 shown, the adjusting assembly 1 includes at least one adjusting seat. The adjusting seat is provided with a strip-shaped installation groove along the vertical direction for detachably installing the material receiving rod 2. In this embodiment, there are two adjusting seats, and one of the upper adjusting seats 102 is arranged upward, and the other lower adjusting seat 101 is arranged downward. The upper adjusting seat 102 and the lower adjusting seat 101 are respectively provided with strip-shaped installation grooves along the vertical direction. The material receiving rod 2 can be fixed in any one of the strip-shaped installation grooves by bolts, thereby realizing the adjustable height of the material receiving rod 2. The lengths of the two strip-shaped grooves are the height adjustment range of the material receiving rod 2.

[0052] Of course, the adjusting component 1 may also include only one adjusting seat, which may be a combination of the two adjusting seats in the above embodiment, or one of the adjusting seats may be selected. The adjusting seat is fixed in a detachable manner (such as threaded connection), and thus can be fixed above or below the linear guide rail 702 according to requirements.

[0053] Further, the adjusting seat includes an installation part and an adjusting part. The strip-shaped installation groove is arranged in the adjusting part. The installation part is horizontally arranged along a direction perpendicular to the material receiving end, the adjusting part is arranged at an angle with the installation part vertically, and the included angle between the installation part and the adjusting part is greater than or equal to 80° and less than or equal to 90°.

[0054] Preferably, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 , the material receiving mechanism further includes a driving component 7, and the driving component 7 includes:

[0055] A cylinder seat 701, arranged on the frame;

[0056] A linear guide rail 702, horizontally arranged on the cylinder seat 701 along a direction perpendicular to the material receiving end, and the adjusting component 1 is detachably installed on the linear guide rail 702;

[0057] A driving cylinder 703, arranged on the cylinder seat 701 and connected to the adjusting component 1, and the driving cylinder 703 is used to drive the adjusting component 1 to move along the linear guide rail 702.

[0058] In this embodiment, the adjusting component 1 is detachably installed on the linear guide rail 702. The driving cylinder 703 is used to control the adjusting component 1 to move along the linear guide rail 702, driving the material receiving rod 2 to move, so that the material receiving rod 2 approaches or moves away from the material receiving end.

[0059] Of course, in addition to cylinder drive, other ways such as motor + gear rack, motor + synchronous belt can also be used to drive the adjusting component 1 to move, and the present utility model does not limit this.

[0060] Preferably, the material receiving mechanism further includes a pressing component 5. The pressing component 5 is arranged on the material receiving rod 2 and is used to press the fabric. The pressing component 5 is mainly used to press the fabric placed on the material receiving rod 2. It should be understood that the material receiving mechanism can repeat the material receiving steps to realize the collection of multiple pieces of fabric. Therefore, after the collection of the previous piece of fabric is completed, the pressing component 5 can be used to press the collected fabric to prevent the fabric from accidentally slipping to the ground when following the material receiving rod 2 to move.

[0061] Further, please refer to Figure 6 , and in combination with Figures 1-4 , the pressing component 5 includes:

[0062] The rotating seat 501 is rotatably mounted on the material receiving rod 2;

[0063] The pressing cylinder 502 is arranged on the material receiving rod 2, and the pressing cylinder 502 is connected to one end of the rotating seat 501 to drive the rotating seat 501 to rotate relative to the material receiving rod 2;

[0064] The cloth clamping plate 503, one end of the cloth clamping plate 503 is connected to the other end of the rotating seat 501, the other end of the cloth clamping plate 503 is a free end, and the free end is used to press the cloth on the material receiving rod 2.

[0065] In this embodiment, the rotating seat 501 can rotate in the vertical plane. The pressing cylinder 502 drives the rotating seat 501 to rotate relative to the material receiving rod 2, and drives the cloth clamping plate 503 to rotate relative to the material receiving rod 2. When collecting the cloth, the pressing cylinder 502 drives the cloth clamping plate 503 to rotate upward and lift. After the cloth collection is completed, the pressing cylinder 502 drives the cloth clamping plate 503 to rotate downward and press the cloth on the material receiving rod 2.

[0066] Preferably, the relative position of the cloth clamping plate 503 and the rotating seat 501 is adjustable;

[0067] The cloth clamping plate 503 is provided with a strip-shaped fixing groove, and the rotating seat 501 is correspondingly provided with a fixing hole. The strip-shaped fixing groove and the fixing hole are connected by a fastener.

[0068] By using the strip-shaped fixing groove to adjust the relative position of the cloth clamping plate 503 and the rotating seat 501, the acting point of the cloth clamping plate 503 on the cloth can be changed to better fix the cloth, so as to adapt to the pressing of cloths with different widths. For example, when the width of the cloth is relatively narrow, drive the cloth clamping plate 503 to move towards the rotating seat 501, align the strip-shaped fixing groove with the fixing hole and tighten with fasteners such as bolts; when the width of the cloth is relatively wide, drive the cloth clamping plate 503 to move away from the rotating seat 501, align the strip-shaped fixing groove with the fixing hole and tighten with fasteners such as bolts.

[0069] In this embodiment, the material receiving end has an inclined surface, and the fabric slides down along the inclined surface. The air blowing assembly includes an upper air blowing group 3 and a lower air blowing group 4. The upper air blowing group 3 is located at the top of the inclined surface, and the lower air blowing group 4 is located at the bottom of the inclined surface. Both the upper air blowing group 3 and the lower air blowing group 4 include a plurality of air blowing holes, and air is blown through the air blowing holes to the fabric so that the fabric can be turned over the material receiving rod 2. By respectively arranging the upper air blowing group 3 and the lower air blowing group 4 at the top and the bottom of the inclined surface, it can be applicable to the air blowing of fabrics with different lengths. For example, when receiving short-sized fabrics, air is blown through the air blowing holes of the upper air blowing group 3, and when receiving long-sized fabrics, air is blown through the air blowing holes of the lower air blowing group 4. The function of blowing the fabric over the material receiving rod 2 can be achieved by the way of air blowing, and the structure is simple and the operation is convenient.

[0070] In this embodiment, there are no restrictions on the shape, quantity, and distribution of the air blowing holes of the upper air blowing group 3 and the lower air blowing group 4.

[0071] Preferably, a fabric placing plate 6 is arranged on the material receiving rod 2. The cross-sectional area of the fabric placing plate 6 is larger than the cross-sectional area of the material receiving rod 2. By arranging the fabric placing plate 6 to collect the fabric, the contact area with the fabric can be increased, preventing the fabric from accidentally slipping.

[0072] It should be noted that Figures 1-2 It shows the situation where the material receiving rod 2 is arranged on both the upper adjusting seat 102 and the lower adjusting seat 10. The upper adjusting seat 102 is equipped with the fabric placing plate 6, and the lower adjusting seat 101 is not equipped with the fabric placing plate 6. However, in actual use, only one of the upper adjusting seat 102 and the lower adjusting seat 10 needs to be selected according to the length of the fabric to install the material receiving rod 2.

[0073] The material receiving process of the material receiving mechanism provided by the embodiment of the present utility model is as follows:

[0074] When sewing the fabric, the fabric that has completed sewing is moved by the drag cloth roller behind the sewing needle. After the fabric is sewn, it slides down along the inclined surface and passes through the air blowing assembly and then falls into the inner side of the material receiving rod 2. During this process, the cloth clamping plate 503 fits on the material receiving rod 2 (not lifted);

[0075] When about half of the fabric falls into the inner side of the material receiving rod 2, the driving cylinder 703 is used to drive the adjusting assembly 1 to move towards the material receiving end and drive the material receiving rod 2 to move to press the fabric (this part of the fabric is pressed between the material receiving rod 2 and the material receiving end);

[0076] The pressing cylinder 502 is used to drive the cloth clamping plate 503 to rotate upwards and lift, and then drive the remaining part of the fabric to continue to move. Under the action of the air blowing assembly, the remaining fabric is blown up to turn over the material receiving rod 2 and fall outside the material receiving rod 2. At this time, the fabric is placed on the material receiving rod 2;

[0077] The pressing cylinder 502 drives the cloth clamping plate 503 to rotate downward and press the cloth on the material receiving rod 2, completing the collection of one piece of cloth;

[0078] Repeat the above actions to collect the next piece of cloth.

[0079] Based on this, the embodiment of the present utility model further provides a welt machine, including the material receiving mechanism as described above.

[0080] In summary, the embodiment of the present utility model provides a material receiving mechanism and a welt machine. Since the vertical position of the material receiving rod 2 on the adjusting assembly 1 is adjustable, the vertical height of the material receiving rod 2 can be adjusted according to the length of the cloth to adapt to the collection of cloths of different lengths.

[0081] In addition, it should also be recognized that although the present utility model has been disclosed above with preferred embodiments, the above embodiments are not intended to limit the present utility model. For any person skilled in the art, without departing from the scope of the technical solution of the present utility model, many possible changes and modifications can be made to the technical solution of the present utility model by using the technical content disclosed above, or modified into equivalent embodiments with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still belong to the scope of protection of the technical solution of the present utility model.
