Specific implementation manners

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0026] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figure shown by the present utility model, and are hereby explained together.

[0027] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0028] As Figures 1 to 6 shown, a positioning device for carton production includes a base 1, and a workbench 2 is fixedly provided on the top surface of the base 1. The cardboard to be cut can be placed on the surface of the workbench 2, and a cutting structure can be externally connected to one side of the workbench 2 on the top surface of the base 1 to cut the cardboard. The cutting structure can be set as an existing cutting structure in the current cardboard cutting field, as long as it can cut the cardboard.

[0029] One side of the workbench 2 is provided with an empty groove 3 running through it. The inner walls on both sides of the empty groove 3 are rotatably connected with a bidirectional threaded rod 4. One side of the workbench 2 is equipped with a driving motor, and the output shaft of the driving motor penetrates through the workbench 2 and is fixedly connected to one end of the bidirectional threaded rod 4. Two cross blocks 5 are threadedly sleeved on the periphery of the bidirectional threaded rod 4. The top and bottom surfaces of the two cross blocks 5 are in frictional contact with the inner top wall and inner bottom wall of the empty groove 3 respectively. The lengths of the two cross blocks 5 are both longer than the length of the empty groove 3. On the top surfaces of the two cross blocks 5 and on both sides of the workbench 2, movable blocks 6 for restricting the cardboard are fixedly provided. The two movable blocks 6 are both arranged in an inverted U shape. The inner bottom walls of the two movable blocks 6 are in frictional contact with the top surface of the workbench 2. By turning on the driving motor, the driving motor drives the bidirectional threaded rod 4 to rotate, so that the bidirectional threaded rod 4 can drive the two cross blocks 5 to move respectively. When the two cross blocks 5 move, they will drive the two movable blocks 6 to move respectively, so that the two movable blocks 6 can move on the surface of the workbench 2 in opposite or relative directions, and then the two movable blocks 6 can abut against both sides of the cardboard to restrict the cardboard.

[0030] On the top surfaces of the two movable blocks 6, brackets 16 are installed. The opposite side surfaces of the two brackets 16 are hollowed out. Inside the brackets 16 and on the top surfaces of the two movable blocks 6, bolts 17 are rotatably connected. The top ends of the bolts 17 penetrate above the brackets 16 and are fixedly provided with turning handles. On the peripheries of the two bolts 17, pressing blocks 18 arranged in an L shape are threadedly sleeved. One end of the pressing block 18 is arranged on one side of the movable block 6. When the two movable blocks 6 restrict the cardboard, turn the turning handle, so that the turning handle drives the bolt 17 to rotate, and the bolt 17 can drive the pressing block 18 to move downward, so that the pressing block 18 can press the cardboard, thereby fixing the cardboard and facilitating subsequent cutting operations.

[0031] On the opposite sides of the two movable blocks 6, a first push plate 7 and a second push plate 8 for pushing the scrap are respectively provided. One side surface of the first push plate 7 and the second push plate 8 is arc-shaped. On the side surface of the first push plate 7 facing the second push plate 8, a through groove 9 for the second push plate 8 to pass through is provided. The length of the second push plate 8 is longer than that of the first push plate 7. When the scrap remains on the surface of the workbench 2, by pushing the first push plate 7, the first push plate 7 will drive the second push plate 8 to move through the through groove 9, so that the first push plate 7 and the second push plate 8 will move along the surface of the workbench 2, thereby pushing the scrap remaining on the surface of the workbench 2. On the opposite side surfaces of the first push plate 7 and the second push plate 8, limiting blocks 12 are fixedly provided. On the opposite side surfaces of the two movable blocks 6 and above the workbench 2, limiting grooves 13 adapted to the limiting blocks 12 are provided. When the first push plate 7 and the second push plate 8 move, they will both move through the limiting blocks 12 in the inner cavity of the limiting grooves 13, thereby restricting the first push plate 7 and the second push plate 8 on the surface of the workbench 2. It also ensures that when the two movable blocks 6 move in opposite or relative directions, they will respectively drive the first push plate 7 and the second push plate 8 to move, and in cooperation with the setting of the through groove 9, the first push plate 7 and the second push plate 8 can push the scrap remaining in different spaces between the two movable blocks 6, ensuring that the first push plate 7 and the second push plate 8 can clean the scrap, so that the staff can clean the scrap by pushing the first push plate 7, reducing the situation that the remaining scrap is inconvenient to clean and affecting the subsequent cutting, and improving the efficiency of carton processing.

[0032] On one side surface of the second push plate 8, a rectangular block 11 is installed. On the inner side wall of the through groove 9, a rectangular groove 10 slidably adapted to the rectangular block 11 is provided, which can restrict the connection between the first push plate 7 and the second push plate 8. The rectangular block 11, the rectangular groove 10, the limiting block 12 and the limiting groove 13 are all T-shaped, which can perform secondary restriction between the first push plate 7 and the second push plate 8 and restriction with the movable block 6, avoiding the first push plate 7 and the second push plate 8 from separating from each other and from the two movable blocks 6.

[0033] On the top surface of the base 1 and on one side of the workbench 2, a through groove 14 for the cardboard scrap to pass through is provided. Inside the base 1, a collection cabinet 15 for collecting the scrap is provided. The scrap pushed by the first push plate 7 and the second push plate 8 will pass through the through groove 14 and fall into the collection cabinet 15 for collection. Inside the collection cabinet 15, a cylinder is fixedly provided on the inner side wall. The piston cylinder of the cylinder is equipped with a pressing plate. After the scrap falls into the collection cabinet 15, the cylinder is started, and the cylinder drives the pressing plate to move, so that the pressing plate can press the scrap, thereby reducing the space occupied by the scrap in the collection cabinet 15, and then enabling the collection cabinet 15 to store more scrap.

[0034] Working principle:

[0035] The positioning device for carton production places the cardboard to be cut on the surface of the workbench 2, and starts the driving motor. The driving motor drives two movable blocks 6 to move in opposite directions through the bidirectional threaded rod 4 and two cross blocks 5, so that the two movable blocks 6 respectively abut against both sides of the cardboard. At this time, the pressing block 18 is driven to move downward by the bolt 17, so that the pressing block 18 abuts against the cardboard for fixation. Then, it can be cut by an externally connected cutting structure. After cutting, there will be scraps left on the surface of the workbench 2. At this time, push the first push plate 7, and the first push plate 7 will drive the second push plate 8 to move synchronously, so that the first push plate 7 and the second push plate 8 push the scraps left on the surface of the workbench 2. The scraps will be pushed into the through groove 14 and fall into the collection cabinet 15 through the through groove 14, so that the staff only needs to push the first push plate 7 to clean the remaining scraps, reducing the situation that the remaining scraps are inconvenient to clean and affecting the subsequent cutting, improving the efficiency of carton processing. At this time, start the air cylinder, let the air cylinder drive the extrusion plate to move, and let the extrusion plate extrude the scraps, so as to reduce the space of the scraps in the collection cabinet 15, and thus be able to store more scraps.
