For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Example

[0031] like Figure 1-3 As shown, an apron cloth cutting machine proposed in the present application includes an operating table 1 and an inverted U-shaped support frame 2 installed on the upper end of one side thereof, and also includes: a blade 3 located on the inner side of the inverted U-shaped support frame 2, a knife groove 8 is opened at the upper end of the operating table 1, and the blade 3 is located directly above the knife groove 8 to avoid direct collision between the blade 3 and the operating table 1 when cutting cloth. The blade 3 is driven by a driving member 4, and a protective cover 5 is provided on the outer cover of the blade 3. When not cutting, the cutting end of the blade 3 is higher than the bottom end of the protective cover 5 to avoid the worker's hand from passing through the bottom end of the blade 3 and contacting the blade 3 when operating. A positioning auxiliary member 6 for controlling the protective cover 5 is provided on one side of the driving member 4; the driving member 4 includes a driving plate 43 fixedly connected to the blade 3, and the positioning auxiliary member 6 includes a transmission plate 61 fixedly connected to one side of the driving plate 43, and an elastic rod 63 is slidably connected to the transmission plate 61, and the bottom of the elastic rod 63 is fixedly connected to the protective cover 5 through a connecting plate 62. When the driving plate 43 moves downward, it drives the transmission plate 61 to move downward, and finally causes the protective cover 5 to move downward until it contacts the upper surface of the operating table 1.

[0032] Furthermore, the positioning auxiliary member 6 also includes a spring 64 sleeved on the outside of the elastic rod 63, and the lower surface of the transmission plate 61 is connected to a limit rod 65, which is used to press the protective cover 5 when cutting the cloth. When the protective cover 5 contacts the upper end surface of the operating table 1, the blade 3 will continue to move downward. At this time, under the elastic force of the spring 64, the protective cover 5 and the connecting plate 62 will buffer and move upward for a certain distance until the limit rod 65 contacts the connecting plate 62. When the connecting plate 62 contacts the limit rod 65, the protective cover 5 and the connecting plate 62 no longer move upward, which plays a role in positioning and pressing the cloth during cutting. A pair of through holes are opened at the upper end of the inverted U-shaped support frame 2, and the driving member 4 is divided into two groups. The driving member 4 also includes a support tube 41 fixedly connected to the upper end of the through hole, and the inner wall of the support tube 41 is installed with a first cylinder 42, and the telescopic end of the first cylinder 42 is fixedly connected to the driving plate 43.

[0033] The working principle of this embodiment is as follows: first, the apron cloth to be cut is passed through the bottom end of the protective cover 5. Since the blade end of the blade 3 is located inside the protective cover 5 and higher than the bottom end of the protective cover 5 when not cut, it can play a role of safety protection during operation to prevent the worker's hand from touching the blade 3. After measuring the cutting size of the cloth, first start the first cylinder 42, and the telescopic ends of the two first cylinders 42 extend to drive the two driving plates 43. Move downward, the two driving plates 43 move downward to drive the blade 3 to move downward a certain distance. With the assistance of the positioning auxiliary member 6, the driving plate 43 moves downward and also drives the protective cover 5 to move downward. When the bottom end of the protective cover 5 contacts the upper end of the operating table 1, even if the driving plate 43 continues to move downward, under the action of the spring 64 and the elastic rod 63, the protective cover 5 and the connecting plate 62 will buffer upward a certain distance, and the blade 3 continues to move downward to cut the cloth. By setting a pair of limit rods 65 on the lower surface of the transmission plate 61, when cutting the cloth, the limit rods 65 contact the connecting plate 62, so that the protective cover 5 and the connecting plate 62 no longer move upward, and the protective cover 5 is pressed against the upper end of the cloth, which plays a stable positioning role for the cloth during cutting. After the cutting is completed, the telescopic ends of the two first cylinders 42 are retracted to the original state, the blade 3 and the protective cover 5 are both raised upward, and with the assistance of the spring 64, the bottom end of the protective cover 5 will quickly return to a position lower than the cutting end of the blade 3. Example

[0034] The utility model provides an apron cloth cutting machine, based on the first embodiment, as Figure 1-4 As shown, this embodiment also includes: a cloth pressing assembly 7 located on one side of the protective cover 5 is arranged above the operating table 1, which is used to position the end of the cloth after cutting to prevent the end of the cloth from rebounding and detaching from the operating table 1 after cutting. The cloth pressing assembly 7 includes a connecting tube 71 connected to the inner wall of the inverted U-shaped support frame 2, and the bottom end of the connecting tube 71 is connected to an arc-shaped airbag 72, and the arc-shaped airbag 72 presses the cloth when it swells. A piston plate 73 is slidably connected in the connecting tube 71, and the arc-shaped airbag 72 is deflated and swelled by moving the piston plate 73 up and down. The upper end of the piston plate 73 is fixedly connected to a pneumatic plate 74, and a second cylinder 75 is installed on one side of the inverted U-shaped support frame 2 through a protrusion, and the telescopic end of the second cylinder 75 is fixedly connected to the pneumatic plate 74, and the fixing and loosening of the cloth are completed by the telescopic movement of the second cylinder 75.

[0035] The working principle of this embodiment is as follows: when cutting the cloth, the telescopic end of the second cylinder 75 is in an extended state, and the arc-shaped airbag 72 is in an inflated state, pressing against the upper end of the cloth to prevent the end of the cloth from bouncing up after the cloth is cut. When it is necessary to continue pulling the cloth, the telescopic end of the second cylinder 75 is retracted to drive the pneumatic plate 74 to move upward, and the pneumatic plate 74 moves upward to drive the piston plate 73 to move upward, and finally the arc-shaped airbag 72 is in a negative pressure state, the arc-shaped airbag 72 is deflated, and the positioning of the cloth is completed. After the size of the cloth is determined, the telescopic end of the second cylinder 75 is extended to drive the piston plate 73 to move downward, so that the arc-shaped airbag 72 is inflated to position the cloth. The positioning method is simple, and the positioning will not cause local indentations on the cloth, causing damage to the cloth.
