Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, a receiving and pressing mechanism of a printing machine includes a frame 1 for printing paper, a printing unit (not shown), and a receiving device disposed at one end of the frame 1. Printing the paper to be processed in the printing assembly in a coiled manner, printing a pre-designed pattern on the paper, and taking out the paper roll printed by the material receiving device after the pattern printing on the surface of the paper is finished so as to perform the next procedure of paper cup processing.

Wherein, material collecting device is including rotating the material roller 5 of receiving of connecting in frame 1 tip top, and the both ends of receiving material roller 5 all stretch into in frame 1 and be connected with the motor (not shown in the figure) in the frame 1, and the motor drive through in the frame 1 receives material roller 5 and rotates in order to receive the paper rolling gradually that the printing is accomplished on material roller 5.

The material collecting device further comprises a pressing component 2 above the material collecting roller 5, and the pressing component is used for pressing paper rolled on the circumferential sides of the material collecting roller 5 so as to flatten the paper, reduce the gap between the paper and increase the flatness of the paper.

Referring to fig. 2 and 3, the pressing assembly 2 includes a pair of pressing frames 21 movably disposed on opposite inner sides of the frame 1, and two ends of the pressing frames 21 away from each other are connected with a driving assembly 4 for lifting the pressing frames 21 to move in a direction away from the material receiving roller 5. The driving assembly 4 is a cylinder 41, a cylinder body 411 of the cylinder 41 is fixed on the frame 1, a cylinder shaft 412 is connected with the end of the pressing frame 21, and meanwhile, the two sides of the frame 1 are provided with adjusting grooves 11 on the movement track of the end of the pressing frame 21 so that the pressing frame 21 can slide.

The pressing assembly 2 further comprises a pressing roller 22 which is rotatably connected between the pair of pressing frames 21, a pair of spiral grooves 221 which are opposite in spiral direction are formed in the peripheral side of the pressing roller 22, when the pressing roller 22 rotates, due to the fact that the spiral directions of the two spiral grooves 221 are different, when the pressing roller 22 contacts paper, the two spiral grooves 221 generate acting forces in two different directions for the paper, the paper is flattened, and wrinkles in the paper rolling process are reduced.

An adjusting component 3 for adjusting the position of the pressing roller 22 is arranged between the two ends of the pressing roller 22 and the pair of pressing frames 21; each group of adjusting components 3 comprises an adjusting rod 31 movably connected between the upper end surface and the lower end surface of the pressing frame 21 along the vertical direction and a connecting rod 33, one end of which is sleeved on the periphery of the adjusting rod 31, and the other end of which is hinged with the end of the pressing roller 22. When the material receiving roller 5 continuously receives the processed paper so that the thickness of the paper on the material receiving roller is gradually increased, the position of the pressure roller 22 is adjusted under the combined action of the adjusting rod 31 and the connecting rod 33 along with the increase of the thickness of the paper by the pressure roller 22, and the self gravity of the pressure roller 22 is also adjusted

The axial dimension of the pressure roller 22 is greater than the axial dimension of the wind-up roller. If the axial dimension of the pressing roller 22 is smaller than the axial dimension of the material receiving roller 5, when the thickness of the paper wound on the material receiving roller 5 is gradually increased along with the production process, the paper blocks the pressing frame 21, the adjusting component 3 is clamped, and when the axial dimension of the pressing roller 22 is larger than the axial dimension of the material receiving roller 5, the smoothness of the adjusting component 3 during working is improved.

The upper end surface and the lower end surface of the pressing frame 21 are both provided with sliding grooves 211 along the horizontal direction, and the two ends of the adjusting rod 31 are respectively embedded into the sliding grooves 211 on the upper end surface and the lower end surface of the pressing frame 21 and slide in the sliding grooves 211. Paper on the wind-up roll carries on progressively thickly along with the process of production and processing, compression roller 22 will remove along with paper thickness, connecting rod 33 rotates this moment and connecting rod 33 slides on adjusting pole 31, because the pole length of connecting rod 33 is unchangeable, when connecting rod 33 rotates, connecting rod 33 will promote to adjust pole 31 and slide in spout 211, in order to realize adjusting part 3's regulating action, can adjust the position of compression roller 22 along with paper thickness when paper thickness increases, and then compress tightly and flatten the paper, the paper surface unevenness after the rolling has been reduced, and then the yields of paper printing in-process improves.

The utility model discloses a theory of operation and beneficial effect do:

the utility model discloses an adjust pole 31 and connecting rod 33 in adjusting part 3, receive material roller 5 and last rolling paper of having processed the completion make receive the paper thickness on the material roller 5 and progressively increase, pinch roller 22 is adjusting its position under the combined action of adjusting pole 31 and connecting rod 33 along with the paper thickness increase, and carry out compressing tightly that lasts to the paper under the combined action of pinch roller 22 and spring 6, and flatten the paper under the effect of a pair of helicla flute 221 opposite in spiral direction, in order to increase the roughness on paper surface behind the rolling, and then improve the yields in the paper printing processing production process.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, 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.
