DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings and embodiments:

Embodiment 1: Referring to FIGS. 1 to 4 , a material receiving device comprises a frame 1, a rotating shaft 2 rotatably mounted on the frame 1, and a right positioning plate 3 arranged on the right side of the rotating shaft 2, wherein the frame 1 is provided with a first driving mechanism for driving the rotating shaft 2 to rotate, and a left positioning plate 4 is installed on the left outer surface of the rotating shaft 2;

A slide rail 5 parallel to the rotation shaft 2 is provided on the frame 1 on the right side of the rotation shaft 2, a bracket 6 is slidably provided on the slide rail 5, the right positioning plate 3 is rotatably connected to the left side of the bracket 6, and a second driving mechanism for pushing the bracket 6 to move along the slide rail 5 is provided on the right side of the slide rail 5;

The rotating shaft 2 is coaxially arranged with the right positioning disk 3 . A positioning rod 7 is arranged on the left side of the right positioning disk 3 . The positioning rod 7 is arranged parallel to the side of the axis of the right positioning disk 3 .

Wherein, when the bracket moves to the left, the right positioning plate is arranged close to the right end surface of the rotating shaft, or the right positioning plate abuts against the right side surface of the rotating shaft, and the positioning rod is arranged parallel to the side of the rotating shaft. In this embodiment, after the bracket moves to the left and is in place, the left side surface of the right positioning plate abuts against the right side surface of the rotating shaft.

In this embodiment, in actual use, the end of the product (paper, label, thermal paper, film product) will be pulled to the top of the rotating shaft by a manipulator or a traction mechanism, and its end will be at the front end of the rotating shaft, and the end of the product will automatically fall down and abut against the top surface of the rotating shaft under the weight. The product can also be released, and the end of the product will fall down and be at the front end or rear end of the rotating shaft. When the product is moved to the left, the left side of the right positioning disk contacts the right side of the rotating shaft, and the push rod is also above the rotating shaft, and the end of the product is between the positioning rod and the rotating shaft. Then the first driving mechanism drives the rotating shaft and the left positioning disk to rotate. In this process, since the end of the product is between the rotating shaft and the positioning rod, the end of the product will be restricted, the rotating shaft and the positioning rod will clamp the product, and drive the product to be rolled up, so that the product is rolled up by the rotating shaft. At the same time, when the rotating shaft rotates, since the right end face of the rotating shaft contacts the left side face of the right positioning disk, the pressing force between the two will simultaneously drive the right positioning disk to rotate, so that the product is rolled up between the left positioning disk and the right positioning disk. When the roll reaches the predetermined length, the first drive mechanism stops driving the shaft to rotate, the product is cut, and then the second drive mechanism drives the bracket to move to the left, which drives the right positioning plate and the positioning rod to move to the right to separate from the product roll, and then the unloading mechanism is used to separate the rolled product from the shaft to the right, and then wait for the next product to be rolled, and so on. In this way, there is no need to manually limit the end of the product, and it can be automatically positioned, which is efficient and effectively reduces the labor intensity of the operator.

As shown in FIGS. 1 to 4 , a strip through groove 8 is provided on the right positioning plate 3 , the inner end of the strip through groove 8 is arranged toward the center of the right positioning plate 3 , and the outer end of the strip through groove 8 is arranged close to the outer edge surface of the right positioning plate 3 ;

The right end of the positioning rod 7 is installed in the strip-shaped through groove 8 via a connecting piece 9. The provision of the strip-shaped through groove can adjust the distance between the positioning rod and the axis of the right positioning plate, that is, can adjust the distance between the positioning rod and the outer surface of the rotating shaft, which is suitable for products of different thicknesses and products in different positions, and can ensure that the end of the product is between the positioning shaft and the rotating shaft, and ensure that the positioning rod limits the end of the product.

As shown in FIGS. 1 to 4 , the connecting member 9 is slidably disposed in the strip-shaped through groove 8 , the left side of the connecting member 9 is disposed in the strip-shaped through groove 8 , and the right end of the connecting member 9 is disposed on the right side of the right positioning plate 3 ;

A limiting bolt 10 is screwed on the right side of the connecting member 9 , and the left end of the limiting bolt 10 abuts against the right side surface of the right positioning plate 3 .

In this embodiment, when the position of the positioning rod needs to be adjusted, the limit bolt is loosened so that the connecting piece can slide in the bar-shaped through groove. After the position adjustment is completed, the limit bolt is tightened to limit the connecting piece in the bar-shaped through groove, that is, the position of the positioning rod is fixed.

Furthermore, in order to ensure that the connector can slide normally in the strip groove, the strip groove 8 includes a left strip groove 11 and a right strip groove 12 that are interconnected, and the width of the left strip groove is greater than the width of the right strip groove, so that the strip groove forms a T-shaped structure, so that the left side of the connector will not be exposed from the left side of the strip groove, which does not affect the winding of the product. The connector is also a T-shaped structure, and the right side of the connector is provided with an extension plate 13 extending forward or backward, which will be located beside the strip groove, and the limit bolt is directly screwed on the extension plate, so that the limit bolt is against the right side of the right positioning plate.

As shown in Figures 1 and 2, the first driving mechanism includes a first motor 14, and the first motor is configured to drive the rotating shaft to rotate; wherein, the output shaft of the first motor can be directly connected to the left end of the rotating shaft, so that the first motor can directly drive the rotating shaft to rotate. Of course, the first motor can also be connected to the rotating shaft through a belt, a pulley is provided on the output shaft of the first motor, and a pulley is also provided on the left end of the rotating shaft, and the belt is wound on the two pulleys, so that the first motor can drive the rotating shaft to rotate through the belt. In this embodiment, the output shaft of the first motor is directly connected to the left side of the rotating shaft.

As shown in Fig. 1 and Fig. 2, the second driving mechanism includes a transverse cylinder 15, and the output shaft on the left side of the transverse cylinder is connected to the right side of the bracket. When the output shaft of the transverse cylinder extends, it drives the bracket and the right positioning plate to move to the left, so that the right positioning plate contacts the right end of the rotating shaft, and the positioning rod is outside the rotating shaft. When the output shaft of the transverse cylinder retracts, it drives the right positioning plate and the positioning rod to move to the right, so that the right positioning plate and the positioning rod are away from the rotating shaft, and the positioning rod is separated from the rolled product roll, which does not affect the separation of the product roll from the rotating shaft.

Embodiment 2: Referring to Figures 5 and 6, a material receiving device is basically similar in structure to Embodiment 1, except that a left conical head 16 is provided on the right side surface of the left positioning disk 4, the right side diameter of the left conical head is smaller than the left side diameter of the left conical head, and the right outer edge of the left conical head is connected to the outer edge surface of the rotating shaft.

A right conical head 17 is provided on the left side surface of the right positioning plate 3, the left diameter of the right conical head is smaller than the right diameter of the right conical head, and the left diameter of the right conical head is equal to the right diameter of the left conical head.

In the first embodiment, the product is directly wound on the rotating shaft. In the present embodiment, it is necessary to first sleeve a paper tube 18 on the outside of the rotating shaft as an inner support for the product winding. When in use, the manipulator or the traction mechanism first pulls the end of the product to the top of the rotating shaft, which will be above the paper tube. There will also be a paper tube feeding mechanism to send the paper tube between the rotating shaft and the right positioning plate (the end of the product is above the paper tube). Then the right positioning plate moves to the left, and the right outer diameter of the right conical head is larger than the inner diameter of the paper tube. The right conical head will first be inserted into the right end of the paper tube, and the left end of the paper tube will be sleeved on the rotating shaft first. At the same time, the paper tube feeding mechanism will be disengaged, and then the right positioning plate will continue to move to the left, pushing the paper tube to move forward. Move left so that the left side of the paper tube is sleeved on the left conical head, and there is a gap between the inner surface of the paper tube and the outer surface of the rotating shaft. The left outer diameter of the left conical head and the right outer diameter of the right conical head are both larger than the inner diameter of the paper tube, so that the paper tube can be supported by the left conical head and the right conical head. In this embodiment, after the horizontal cylinder output shaft is extended, there is a gap between the right positioning plate and the rotating shaft, and the paper tube is tightened by the two conical heads (the positioning rod is above the paper tube, so that the end of the product is between the positioning rod and the paper tube), and then when the first motor drives the rotating shaft to rotate, it can drive the paper tube and the right positioning plate to rotate, so that the product can be rolled up on the paper tube.

In the utility model, the distance between the positioning rod and the rotating shaft can be adjusted, which is not only applicable to different products, but also applicable to whether the structure of paper tube inner support is adopted, and has a wider scope of application.
