Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carton packaging, in particular to a bending and shaping device for carton packaging. Background Art
[0002] The material of cartons is generally corrugated paper. The initial process of the packaging shaping machine is to pre-treat the corrugated paper by indentation to facilitate bending and shaping. The indentation processing device is generally composed of a pressing roller and a servo motor. Two annular protrusions are symmetrically installed on the outer wall of the pressing roller. The outer wall shape of the annular protrusion corresponds to the indentation of the corrugated paper. The annular protrusion is driven by the pressing roller to leave an indentation on the corrugated paper.
[0003] The annular protrusion on the pressing roller is fixed on the outer wall, but the carton production line processes more than one size of carton, so the sizes of corrugated paper are different. The sizes of indentations on corrugated paper of different sizes are also different, but one pressing roller can only process one size of corrugated paper, so corrugated paper of other sizes needs to be equipped with corresponding indentation processing devices, which increases processing costs and limits processing efficiency.

[0015] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.
[0016] like Figure 1-4The shown device is a bending and shaping device for carton packaging, comprising a pressure roller 1 and a shaping assembly installed at the end of the pressure roller 1. Support plates 2 are installed at both ends of the pressure roller 1 through bearings. The support plates 2 are fixedly installed on the cardboard conveyor. The inner walls of the two support plates 2 are fixedly installed with mounting plates 3. The outer walls of the two mounting plates 3 are provided with circular holes. The two mounting plates 3 are installed on the outside of the pressure roller 1 through the circular holes. The shaping assembly comprises a bidirectional screw 6, a motor 4 and two pressure rings 10. The ends of the bidirectional screw 6 are connected to the inner walls of the mounting plates 3 through bearings and are installed above the pressure roller 1.
[0017] The motor 4 is fixedly mounted on the outer wall of one of the mounting plates 3. The output end of the motor 4 passes through the outer wall of the mounting plate 3 and is fixedly connected to the end of the bidirectional screw 6. The two pressure rings 10 are respectively sleeved and mounted on the two ends of the outer wall of the pressure roller 1. A fixing plate 7 is provided on one side of the bidirectional screw 6. The end of the fixing plate 7 is fixedly connected to the mounting plate 3. A guide groove 11 is provided on the outer wall of the fixing plate 7. The outer walls of the two sliders 8 are fixedly mounted with sliding rods 12, and the sliding rods 12 are embedded in the guide groove 11.
[0018] The pressure ring 10 is connected to the bidirectional screw 6 by transmission. Two chute 5 are symmetrically provided on the outer wall of the pressure roller 1. The pressure ring 10 is installed in contact with the outer wall of the pressure roller 1. Two interlocking blocks are symmetrically installed on the inner wall of the pressure ring 10. The interlocking blocks are correspondingly embedded in the chute 5. Sliders 8 are threadedly installed on both ends of the bidirectional screw 6. A magnetic plate 9 is fixedly installed below the slider 8. The magnetic plate 9 is arc-shaped and fits the outer wall of the pressure roller 1. The edge of the magnetic plate 9 is adsorbed and connected to the outer wall of the pressure ring 10. The shape of the magnetic plate 9 is an arc-shaped curved plate of half a circle, which can make the edge of the magnetic plate 9 have a larger contact area with the pressure ring 10, thereby enhancing the firmness of the magnetic adsorption.
[0019] Example: A pressure roller 1 is rotatably mounted on a paper conveyor via a support plate 2. A paper conveyor belt passes beneath the pressure roller 1, and the pressure roller 1 is driven by the paper conveyor's built-in servo system. Initially, a slider 8 is in contact with the inner wall of the mounting plate 3, and two pressure rings 10 are located at either end of the outer portion of the pressure roller 1. Before the corrugated paper passes under the pressure roller 1, the motor 4 rotates the bidirectional screw 6, which in turn drives the two sliders 8 to slide toward the center. Slide bars 12 slide within guide grooves 11 in the fixed plate 7, which are arranged parallel to the bidirectional screw 6. The sliders 8 drive the magnetic plates 9, which in turn move the pressure rings 10 a certain distance until they reach the desired position. The servo system then rotates the pressure roller 1. The interlocking blocks on the inner wall of the pressure ring 10 are embedded within the chute 5. Rotation of the pressure roller 1 drives the pressure rings 10 along with it. After the conveyor belt is activated, the pressure rings 10 create creases in the corrugated paper as it passes beneath the pressure roller 1.
[0020] The sizes of indentations on corrugated paper of different sizes are also different. The distance between the pressure rings 10 is controllable. The pressure rings 10 can move following the slider 8, so that the distance between the two pressure rings 10 is controllable. According to the size of the corrugated paper, the distance between the two pressure rings 10 is adjusted, so that the shaping component can operate on corrugated paper of various sizes.
[0021] It should be noted that the parts not covered in the present invention are the same as the existing technology or can be implemented by using the existing technology; the various drives in the present invention can be implemented by using corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structure in the drawings.
[0022] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
