[0002] The lasting machine is a type of sewing machine, which is mainly used for stretching the heels of shoes. The shoes are put on the die base of the lasting machine for lasting before being sewn to the soles.

[0003] At present, the Chinese invention patent with the announcement number CN104233635B discloses a lasting machine, which is composed of a body, a main feeding mechanism, a needle bar mechanism, a hook needle transmission mechanism, a material blocking mechanism, a feeding moving mechanism, a first driving mechanism and a control unit, wherein the main feeding mechanism is arranged inside the body, and has a feeding shaft connected to the first driving mechanism, and a feeding wheel is installed on the feeding shaft; the feeding moving mechanism has a moving frame and a presser wheel mounted on the moving frame and a second driving mechanism, and the presser wheel and the second driving mechanism are linked to each other. In addition, the control unit transmits the signal of the first driving mechanism to the second driving mechanism to control the rotation rate between the two wheels and change the differential amount thereof; please refer to Figure 1 In the existing lasting machine, a feeding gap 5 is formed between the feeding wheel 3 and the presser wheel 4. The feeding wheel 3 and the presser wheel 4 rollers press the two pieces of fabric tightly. After the hook needle sews the two pieces of fabric together, the two pieces of fabric and the processed fabric are transported forward in the feeding gap 5 through the feeding wheel 3 and the presser wheel 4 rollers.

[0004] Before sewing two pieces of cloth together, an operator is required to manually align the edges of the two pieces of cloth to be sewn and then perform the sewing operation through a lasting machine; however, due to differences in experience, different operators have errors when performing manual edge alignment, resulting in uneven quality of the processed cloth produced, and the manual edge alignment operation is time-consuming and reduces production efficiency. Utility Model Content

[0026] The baffle plate is provided with a second mounting hole, and the connecting frame is provided with a second strip-shaped hole that matches the second mounting hole;

[0027] The second mounting hole is connected to the second strip hole via a second bolt.

[0028] Through the above technical solution, there will be errors in the processing of parts, and the baffle plate and the connecting frame can be adjustably connected to facilitate adjustment to a suitable position during assembly.

[0029] In an embodiment of the present invention, a third strip-shaped hole is formed on the fixing frame.

[0030] Through the above technical solution, the third strip-shaped hole is used to fix the fixing frame to the body of the lasting machine.

[0031] As described above, a material blocking device of the utility model has the following beneficial effects:

[0032] 1. The tops of the guide grooves are at the same height. When sewing, only two pieces of fabric need to be placed in the two guide grooves respectively. The tops of the two pieces of fabric are respectively against the tops of the two guide grooves, so that the edges of the two pieces of fabric can be adjusted to the same height. The two pieces of fabric enter the pressing nozzle, which presses the two pieces of fabric together, so that the edges of the two pieces of fabric are aligned and pressed together to ensure the processing quality; the pressing nozzle guides the pressed fabrics to the feed wheel and the presser wheel, and the feed wheel and the presser wheel roller press the two pieces of fabric tightly. After the hook needle sews the two pieces of fabric together, the feed wheel and the presser wheel roller convey the two pieces of fabric and the processed fabric forward in the feeding gap through friction; thus, there is no need to align the two pieces of fabric manually, which improves production efficiency;

[0033] 2. Since the seam heights of fabrics of different materials are different, the threaded rod can be screwed to enable the connecting frame to drive the baffle plate to slide vertically upward or downward on the fixed frame, thereby adjusting the setting height of the baffle plate, and then adjusting the seam height of the processed fabric, to meet the production needs of different fabrics.
