wherein the pushing assembly comprises

The material pushing platform 32 is provided with an opening 33;

a pushing cylinder 34 disposed above the opening 33 of the pushing platform 32; when the cloth is delivered to the pushing platform 32 and crosses over the opening 33, the pushing cylinder 34 descends to push the cloth onto the storage assembly 31.

As shown in fig. 12, the feeding mechanism 2 is provided at one end of the conveying line 1, and the discharging mechanism 3 is provided at the other end. Specifically referring to fig. 13, the magazine assembly 31 and the material pushing platform 32 are respectively fixed on a bracket at the tail end of the conveyor line 1, the material pushing platform 32 is specifically a cover plate arranged above the material receiving tray, and includes a front cover plate 321 and a rear cover plate 322 which are arranged in parallel, and the opening 33 is formed between the front cover plate 321 and the rear cover plate 322; the front cover plate 321 and the rear cover plate 322 are square, and have a certain width; the material pushing cylinder 34 is specifically a cylinder, a vertically arranged material pushing plate 341 is arranged on the material pushing cylinder 34, the material pushing plate 341 is square, and the material on the opening 33 is pushed by the square edge of the material pushing plate 341; in this embodiment, the front cover plate 321, the rear cover plate 322, the material pushing plate 341, and the opening 33 formed between the front cover plate 321 and the rear cover plate 322 are all wider than the fabric, and the length of the opening 33 is smaller than the length of the fabric; when the cloth is located when opening 33 is last, the material pushing cylinder 34 supports the cloth downwards, and the cloth is fifty percent discount because of front shroud 321 and back shroud 322, and under until whole cloth was pushed into opening 33, because front shroud 321 and back shroud 322 and the opening 33 who takes shape between front shroud 321 and back shroud 322 have certain width, only can the fifty percent discount in the time of so making the cloth propelling movement, and can not produce other extra folds to the quality of the cloth of guaranteeing to a certain extent.

Further, the rear cover plate 322 is disposed lower than the front cover plate 321, so that the cloth can pass through the opening 33 from the front cover plate 321 to the rear cover plate 322 through the height difference; as shown in fig. 14, the mounting angle 35 is fixed on the two sides of the cover plate 32 and used for fixing on the rack, the mounting angle 35 is L-shaped, one side of the mounting angle 35 is fixed on the rack, the other side is provided with a connecting hole for connecting the front cover plate 321 or the rear cover plate 322, and the front cover plate 321 and the rear cover plate 322 are respectively fixed on the front and back sides of the mounting angle 35, so that a height difference of one side of the mounting angle 35 is formed between the front cover plate 321 and the rear cover plate 322. When the cloth is sent to the cover plate 32 and passes through the opening 33, because the cloth has a certain supporting force, when nothing is supported below the cloth, the cloth can be slowly bent downwards until the cloth is vertical, and in the period of time when the cloth passes through the opening 33, if the conveying time is too long, one end of the cloth can be excessively bent to fall into the opening 33, so that abnormal cloth transportation is caused, and the overlapping is influenced; the height difference between the front cover plate 321 and the rear cover plate 322 is compensated for, and the height difference falling during the cloth conveying period is compensated for. In fact, if the conveying speed of the conveying line 1 is high enough, the height difference can be eliminated, and the cloth can span the opening 33.

Further, an L-shaped mounting bracket three 36 is arranged on one side of the pushing platform 32, the pushing cylinder 34 is arranged at the tail end of the mounting bracket three 36 downward, as shown in fig. 14, the bracket is fixed on a rack of the automatic sewing equipment through a connecting piece such as a screw, a sensor three 37 is further fixed on the mounting bracket three 36 and is positioned above the rear cover plate 322 through the mounting bracket three 36, the sensor three 37 can be a photoelectric sensor, and when cloth blocks between the sensor three 37 and the rear cover plate 322, the pushing cylinder 34 works to stack the cloth. In order to ensure the quality of the pushing platform 32, the pushing platform 32 is made of a metal material, and the metal material has a poor sensing effect on the third photoelectric sensor 37, which may affect the operation of the third photoelectric sensor 37, and in order to ensure the normal operation of the third photoelectric sensor 37, the rear cover plate 322 is provided with a sensing portion 371 corresponding to the third photoelectric sensor 37, which is specially adapted to the third photoelectric sensor 37; in this example, the sensing portion 371 may be a sticker, the surface of which may be used for sensing to meet the normal reflective needs at the photosensor three 37.

Further, the material storage component 31 is specifically a material receiving tray, a second lifting component 38 is arranged at the bottom of the material receiving tray, and comprises a second lifting motor 381 and a second lead screw 382 driven by the second lifting motor 381, and the second lead screw 382 is connected with the material storage component 31; because each cloth has a certain thickness, when the cloth is stacked in sequence, the height of the whole cloth pile is gradually increased, but the moving distance of the material pushing cylinder 34 is constant, namely, the general material pushing cylinder 34 is limited up and down through the position of a fixed sensor III 37; the second lifting assembly 38 is arranged to lower the second lifting assembly 38 to compensate for the height difference generated by stacking the cloth after the cloth is stacked in sequence, so that the distance of each movement of the material pushing cylinder 34 is not required, and the second lifting assembly 38 is simpler and more convenient to implement. As shown in fig. 16, a panel is disposed on the other end of the second lead screw 382, and a plurality of second auxiliary lead screws 383 which connect the panel and the bottom of the magazine assembly 31 are disposed on the panel, so that the second lead screws 382 can be lifted more stably.

Further, the storage assembly 31 is provided with a receiving surface 311 for placing the cloth, and in some embodiments, the receiving surface 311 may be a plane; however, the thickness of the discharged cloth may be uneven, but the distance of descending of the second lifting assembly 38 is constant, which may cause the height of the cloth to deviate from the descending height, which may cause the cloth pile on the storage assembly 31 to be too high or too low in the long term, and may damage the material pushing cylinder 34 when the height of the cloth pile exceeds the descending height of the material pushing cylinder 34.

To solve this problem, as shown in fig. 15, the receiving surface 311 includes an inclined section 3111 and a horizontal buffer section 3112. Storage assembly 31 is equipped with the guardrail outward, at storage assembly 31 internally mounted have a panel, panel are equipped with a bending point to the shaping slope section 3111 and buffer section 3112. When the cloth is pushed into the receiving surface 311, the cloth is located at the bending point, and a high point is located at one side of the inclined section 3111 and a low point is located at one side of the buffer section 3112; when the material pushing cylinder 34 works, the material pushing cylinder abuts against the material distribution high point to stack the materials. When the cloth conveyed each time is too thick, the material pushing cylinder 34 abuts on the high point of the cloth, and the cloth pile slides downwards along the inclined section 3111 towards the buffer section 3112, so that the height of the cloth pile is correspondingly reduced, and the problem of height difference caused by uneven cloth is solved through the structure.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
