Description

Technical Field

[0001] The utility model belongs to the technical field of roll paper production, in particular to an automatic roll paper cutting machine. Background Art

[0002] Roll paper is a common type of paper used in daily life. It is usually produced in large rolls and then cut into small rolls for consumers to use, such as toilet paper, kitchen paper, etc. The automatic roll paper cutting machine is an automated device dedicated to cutting large rolls of paper into small rolls of specified length. It completes the unfolding, positioning, cutting and conveying of the paper roll to the next process through an automated process. The automatic roll paper cutting machine is a mechanical device dedicated to cutting large rolls of base paper into small rolls of suitable size. This machine usually includes a cutting unit, a conveying system, a control panel and other components, which can automatically complete the cutting process and improve production efficiency. The existing automatic roll paper cutting machine cuts the paper roll by driving the cutting component to move downward. However, it generates paper scraps during cutting. It lacks a collection mechanism for the paper scraps during the automatic paper roll cutting, which will cause the paper scraps to scatter on the cutting table, resulting in the disadvantage of polluting the workshop environment. It requires personnel to collect and process the paper scraps manually or with the help of an external collection mechanism, which is time-consuming and labor-intensive, and reduces production efficiency.

[0003] For example, the utility model with announcement number CN214081676U discloses an automatic paper roll cutting machine. In this patent scheme, it is not possible to reasonably collect the paper scraps generated when the paper roll is cut. The paper scraps are scattered around the machine and in the working environment, which is not only unsightly, but also affects the cleanliness of the workshop and the health of the workers. The paper scraps will also adhere to the small rolls of paper after cutting, affecting the appearance of the product and the consumer's experience. The operator is required to clean the paper scraps regularly manually or with the help of external tools, thereby reducing production efficiency. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides an automatic paper roll cutting machine. Through the paper scrap collection component, the paper scraps generated during the cutting process are effectively collected, the working environment is kept clean, the surface of the small paper rolls after cutting is ensured to be clean and free of impurities, and the need for manual intervention is reduced, making the production process more consistent and improving the overall production efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an automatic paper roll cutting machine, including a mounting frame, a plurality of rotating rollers are rotatably arranged inside the mounting frame, and the plurality of rotating rollers are connected by a conveyor belt transmission, a connecting plate is arranged on the right side of the upper end of the mounting frame, two electric push rods 2 are arranged on the upper right end of the connecting plate, a rectangular plate is arranged between the telescopic ends of the two electric push rods 2, a cutting knife is arranged at the lower end of the rectangular plate, a discharging plate is arranged on the right side of the mounting frame, and an avoidance groove corresponding to the position of the cutting knife is opened inside the discharging plate, an electric drive unit for driving the rotating roller to rotate is arranged on the rear side of the mounting frame, an auxiliary limiting mechanism is arranged inside the connecting plate, a cutting limiting mechanism is arranged inside the rectangular plate, a collecting assembly is arranged at the lower end of the discharging plate, the electric drive unit includes a motor arranged on the rear side of the mounting frame, and the output shaft of the motor is connected to the rear end of the rotating roller on the left side through a coupling, and the collecting assembly includes a sliding frame arranged at the lower end of the discharging plate, a collecting box is slidably arranged inside the sliding frame, and a handle is arranged on the front side of the collecting box.

[0006] As a further improvement of the present invention, the auxiliary limiting mechanism includes two electric push rods arranged on the left side inside the connecting plate, an auxiliary limiting plate is arranged between the telescopic ends of the two electric push rods, the cutting limiting mechanism includes four sliding columns respectively slidably arranged at the four corners of the rectangular plate, a cutting limit plate is arranged between the lower ends of the four sliding columns, a notch corresponding to the position of the cutting knife is opened inside the cutting limit plate, a plurality of springs are arranged between the rectangular plate and the cutting limit plate, and the plurality of springs are respectively sleeved on the outer arc surfaces of the corresponding sliding columns.

[0007] As a further improvement of the present invention, a control panel is provided on the front side of the mounting frame, and the motor, the first electric push rod and the second electric push rod are all electrically connected to the control panel.

[0008] As a further improvement of the utility model, support frames are respectively provided at the four corners of the lower end of the mounting frame.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, place the roll paper to be cut on the conveyor belt. Then, control the motor to run through the control panel. The output shaft drives the rotating roller to rotate, thereby driving the roll paper on the conveyor belt to move, so that the roll paper moves onto the discharge plate and reaches the appropriate cutting position. Then, turn off the motor. Next, control the first electric push rod to run through the control panel. The telescopic end drives the auxiliary limit plate to move downward to limit the paper roll on the conveyor belt. At the same time, control the second electric push rod to run through the control panel. The telescopic end drives the cutting knife and the cutting limit plate on the rectangular plate to move downward. The cutting limit plate first contacts the upper end of the paper roll, and through the resilience of the elastic body, it realizes the limit of the paper roll on the discharge plate. At the same time, the telescopic end of the second electric push rod continues to push the cutting knife on the rectangular plate downward, and the spring is compressed. The cutting knife passes through the notch to quickly realize the stable limit cutting of the roll paper, which can avoid the situation of displacement during the cutting of the roll paper.

[0011] Second, when the cutting knife cuts the roll paper, the cut paper scraps enter the interior of the collection box through the avoidance groove. Personnel can pull out the collection box through the handle to process the paper scraps inside. Through the paper scrap collection component, the paper scraps generated during the cutting process are effectively collected, keeping the working environment clean, ensuring that the surface of the small roll paper after cutting is clean without impurities, reducing the need for manual intervention, making the production process more coherent, and improving the overall production efficiency.

[0012] Third, the support frame effectively improves the stability of the roll paper cutting machine and the quality during roll paper cutting.

[0013] Fourth, through the control panel, it is convenient for personnel to control the electrical components on the cutting machine, which is convenient for personnel to use. Description of the Drawings
