The above-mentioned mode can efficiently help the workers to complete the cutting work of a fixed length each time, can significantly reduce the size error, and can reduce the working difficulty, and the simple structure will not cause a significant increase in the use cost.

[0025] As shown in the figure, Figure 2 The distance limiting mechanism 2 comprises a baffle 21 which is connected with the guide rod 12 in a sliding manner through two end-fixed connecting sliding cylinders 22, the baffle 21 can block the sliding of the cloth end clamp 3 so that it stops when reaching the specified position, and the connecting sliding cylinders 22 are arranged to facilitate the adjustment of the position of the baffle 21, and a locking bolt 23 is threadedly connected to the connecting sliding cylinder 22, which can fix the position of the connecting sliding cylinder 22 by the friction between the locking bolt 23 and the guide rod 12.

[0027] As shown in the figure, Figure 2 The connecting sliding cylinder 22 is fixedly provided with a bent pointer 24, and the base plate 1 is fixedly provided with a scale bar 25 on which a scale line is drawn, and the end of the bent pointer 24 points to the scale line on the scale bar 25.

[0029] As shown in Figure 2 The cloth end clamp 3 comprises a sliding base 31 slidably arranged on the guide rod 12, a clamp door frame 32 is mounted on the sliding base 31, a movable clamp plate 33 is slidably arranged in the clamp door frame 32, an adjusting screw rod 34 is threadedly connected to the clamp door frame 32, the bottom end of the adjusting screw rod 34 is rotatably connected with the movable clamp plate 33, and a rubber pressing piece 35 is fixedly arranged on the upper end surface of the movable clamp plate 33.

[0030] As shown in Figure 3 The cutting frame 4 comprises a cutting door frame 41 arranged on the feeding frame plate 11, a hydraulic cylinder 42 is mounted on the cutting door frame 41, the output shaft end of the hydraulic cylinder 42 penetrates through the cutting door frame 41 and is connected with a cutter holder 43, a cutting knife 44 is detachably mounted on the cutter holder 43, the hydraulic cylinder 42 can drive the cutting knife 44 to move up and down to complete the cutting of the cloth, and the detachable connection between the cutting knife 44 and the cutter holder 43 can facilitate workers to disassemble the cutting knife 44 for maintenance or replacement.

[0032] The use principle and use process of the utility model are as follows:

[0033] The cloth end clamping fixture 3 is used to clamp and fix the cloth end and adjust the length of cutting by sliding on the guide rod 12 to meet different needs. When cutting cloth of a specific size is needed, the distance limiting mechanism 2 is slid to a specified position. At this time, the maximum distance of the cloth end clamping fixture 3 sliding is limited, that is, the cloth end clamping fixture 3 cannot continue to advance after being in contact with the distance limiting mechanism 2, and at this time, the cut cloth is the cloth length corresponding to the position of the distance limiting mechanism 2. This kind of way can efficiently help workers complete the cutting work of a fixed length each time, can significantly reduce the size error, and reduce the working difficulty, and the simple structure also will not cause the use cost to have the significant growth.

[0034] The baffle 21 can block the sliding of the cloth end clamping fixture 3 so that it stops when reaching the specified position, and the connection sliding cylinder 22 is provided to facilitate the adjustment of the position of the baffle 21, and the connection sliding cylinder 22 is threadedly connected with the locking bolt 23, which can fix the position of the connection sliding cylinder 22, and when the connection sliding cylinder 22 is slid, the value of the scale line on the scale bar 25 pointed by the bent pointer 24 will change synchronously, which can be used as a basis for workers to more accurately adjust the position of the connection sliding cylinder 22, that is, more accurately adjust the length of cutting.

[0035] Based on the above-mentioned cutting length adjustment scheme, the scale line on the scale bar 25 is drawn with the cutting position of the cutting frame 4 as the zero scale, that is, the minimum value of the scale line on the scale bar 25 is a non-zero value. This scheme can make the value corresponding to the scale line be the value of the cut cloth, because the distance from a scale value of the scale line to the cutting position of the cutting frame 4 is the distance from the cloth end clamping fixture 3 to the cutting position.

[0036] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description.
