Description

Technical Field

[0001] The utility model belongs to the technical field of bubble bag processing, in particular to a bubble bag cutting device. Background Technique

[0002] Bubble bags are a commonly used transparent soft packaging material at present, with wide applications. They are mainly used for the buffer packaging of electronic products, plastic products, metal products, ceramic products, glass products, and the logistics transportation protection of other products that require buffer protection. After the production of bubble bags, cutting equipment is needed to cut them so that the size of the bubble bags matches the size of the packages to be wrapped. However, most current cutting devices lack a structure for limiting the bubble bags, and the bubble bags are light in weight, making it easy for the bubble bags to slide and shift during the cutting process, resulting in uneven cut edges and inclined cutting lines. This not only reduces the production quality of the bubble bags but also causes waste of raw materials.

[0003] For example, in the existing Chinese Patent Publication No.: CN213261169U, a bubble bag cutting device, which: "comprises a cutting table, fixed frames are arranged on both sides of the cutting table, bolts are arranged at the connection between the fixed frames and the cutting table, a rotating column is arranged below the fixed frames, a connecting rod is arranged inside the rotating column, a rotating shaft is arranged at the connection between the connecting rod and the fixed frames, and a heating rod is arranged above the rotating column."

[0004] It can be seen that this cited patent document has the problem of easy sliding and shifting during the cutting of bubble bags. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bubble bag cutting device to solve the problems raised in the background technique.

Specific implementation manners

[0023] 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.

[0024] 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 drawings shown in the present utility model, and are hereby explained together.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0026] As Figures 1 to 4 shown, a bubble bag cutting device includes a workbench 1. Legs are installed on the top surface of the workbench 1, which can raise the workbench 1 to a height convenient for the operator. A hydraulic cylinder 16 is fixedly installed on the top surface of the workbench 1 through a bracket. The piston rod of the hydraulic cylinder 16 penetrates the bracket and is provided with cutting teeth 17 for cutting the bubble bag. A driving mechanism can be provided on one side of the cutting teeth 17, and the driving mechanism can be set as a motor to drive the cutting teeth 17 to rotate. The driving mechanism is a conventional mechanism, and only needs to drive the cutting teeth 17 to rotate to cut the bubble bag. After the bubble bag is placed on the surface of the workbench 1, the hydraulic cylinder 16 is turned on, so that the hydraulic cylinder 16 drives the cutting teeth 17 to move downward and abut against the bubble bag, and the driving mechanism is turned on to drive the cutting teeth 17 to rotate to cut the bubble bag.

[0027] On one side of the top surface of the workbench 1, an electric push rod 2 is fixedly installed through a fixing frame. One side surface of the fixing frame is provided with a hollow structure. The output end of the electric push rod 2 penetrates through the fixing frame and is fixedly installed with a pressing plate 3 for restricting the bubble bag. The pressing plate 3 is arranged in the hollow area on one side surface of the fixing frame. After the bubble bag is placed on the surface of the workbench 1, one side of the bubble bag is placed at the hollow of the fixing frame, and at the same time, it is directly below the pressing plate 3. Then, the electric push rod 2 is turned on, and the electric push rod 2 drives the pressing plate 3 to move downward, so that the pressing plate 3 can press against and squeeze the bubble bag, thereby completing the fixation of one side of the bubble bag.

[0028] On the other side of the top surface of the workbench 1, a cylinder 4 is fixedly installed through a vertical plate. The piston rod of the cylinder 4 is horizontally fixedly installed with a cross plate 5. At both ends of the cross plate 5, moving blocks 6 are respectively fixedly installed. The bottom surfaces of the two moving blocks 6 are in frictional contact with the top surface of the workbench 1. The cross plate 5 is arranged in the upper half of the opposite side surfaces of the two moving blocks 6. By turning on the cylinder 4, the cylinder 4 can drive the cross plate 5 to move, and then drive the two moving blocks 6 to move through the cross plate 5, so that the two moving blocks 6 can move on both sides of the bubble bag. Since the cross plate 5 is fixedly installed in the upper half of one side surface of the two moving blocks 6, the cross plate 5 will move above the bubble bag.

[0029] On the top surfaces of the two moving blocks 6, hinge rods 7 are respectively hinged through pin shafts. On the upper half of the opposite side surfaces of the two hinge rods 7, a connecting block 8 is fixedly installed. The connecting block 8 is arranged in an inclined U shape. On the inner walls of both sides of the connecting block 8, a pressing roller 9 for restricting the bubble bag is rotatably connected. After the bubble bag is laid on the surface of the workbench 1, the two hinge rods 7 are pushed, so that the two hinge rods 7 can rotate counterclockwise by ninety degrees, thereby driving the connecting block 8 to rotate counterclockwise by ninety degrees, and then driving the pressing roller 9 to rotate counterclockwise by ninety degrees. And the width of the connecting block 8 is the same as the length between the bottom surface of the moving block 6 and the pin shaft. Therefore, after the connecting block 8 rotates counterclockwise by ninety degrees, the pressing roller 9 will press against the bubble bag on the top surface of the workbench 1. At this time, the cylinder 4 is turned on, so that the cylinder 4 can drive the pressing roller 9 to continue to move through the cross plate 5, the moving block 6, the hinge rod 7 and the connecting block 8, so that the pressing roller 9 can move along the surface of the bubble bag, and the bubble bag can be flattened, which is convenient for subsequent cutting. After the pressing roller 9 moves to one side of the bubble bag, the cylinder 4 can stop moving, so that the pressing roller 9 can fix the other side of the bubble bag, so that the pressing roller 9 and the pressing plate 3 cooperate to fix the bubble bag, which is convenient for subsequent cutting, reduces the situation that the bubble bag is easy to slide and shift during the cutting process, and improves the quality of the bubble bag cutting production.

[0030] On one side of each of the two moving blocks 6, a limiting block 10 is fixedly provided. On one side of the two limiting blocks 10 away from the moving blocks 6, one side of the hinge rod 7 is attached. Threaded holes 11 are provided through one side of the two limiting blocks 10 and one side of the hinge rod 7. In the inner cavities of the two threaded holes 11 where the positions of one side of the two limiting blocks 10 and one side of the two hinge rods 7 are aligned, a first bolt 12 is threadedly connected. When the hinge rod 7 is working and not working, it will present a state of being vertically perpendicular and horizontally perpendicular. When the hinge rod 7 is horizontally perpendicular, the pressing roller 9 can limit the bubble bag. When the hinge rod 7 is vertically perpendicular, the pressing roller 9 will be above the workbench 1, facilitating the taking of the bubble bag. When the hinge rod 7 is in the vertically perpendicular state, one side of the hinge rod 7 will abut against one side of the limiting block 10. At the same time, the threaded hole 11 on one side of the hinge rod 7 will be aligned with the threaded hole 11 on one side of the limiting block 10. At this time, inserting the first bolt 12 into the two threaded holes 11 can fix the hinge rod 7, so that the hinge rod 7 will always be in the vertically perpendicular state, thereby fixing the longitudinal position of the pressing roller 9.

[0031] On one side of the two moving blocks 6 away from the limiting blocks 10, a backing plate 13 is horizontally fixedly provided. Threaded holes 11 with the same connection structure as that of the hinge rod 7 and the limiting block 10 are provided through the top surfaces of the two backing plates 13. When the hinge rod 7 is horizontally perpendicular, one side of the hinge rod 7 away from the limiting block 10 will abut against the top surface of the backing plate 13. Since the distance between the top surface of the backing plate 13 and the axis of the pin shaft is the same as the distance between the axis of the pin shaft and the bottom surface of the hinge rod 7, when the hinge rod 7 is attached to the top surface of the backing plate 13, it will be horizontally perpendicular. At the same time, the threaded hole 11 on one side of the hinge rod 7 will also be aligned with the threaded hole 11 on the top surface of the backing plate 13. Inserting the first bolt 12 into the two threaded holes 11 can fix the horizontal position of the hinge rod 7, so that the pressing roller 9 will always abut against the surface of the bubble bag, preventing the pressing roller 9 from being bounced off by the bubble bag.

[0032] On one side of the connecting block 8, a number of screw holes 14 are equidistantly arranged, each screw hole 14 runs through to the inner side wall of the connecting block 8, and a second bolt 15 is threadedly connected to the inner cavity of each screw hole 14. When the pressure roller 9 needs to restrict the bubble bag, the second bolt 15 is inserted into the screw hole 14 and passes through the screw hole 14, so that the end of the second bolt 15 will be on one side of the pressure roller 9. Then, the second bolt 15 is rotated continuously, so that the end of the second bolt 15 will abut against one side of the pressure roller 9 and continue to move, so that the second bolt 15 can squeeze the pressure roller 9, and with the frictional force of the squeeze, the pressure roller 9 can be restricted, so that the pressure roller 9 will not rotate, avoiding the bubble bag driving the pressure roller 9 to rotate, thus making the pressure roller 9 unable to fix the bubble bag well. The arrangement of multiple screw holes 14 and second bolts 15 can improve the effect of restricting the pressure roller 9. And in normal work, if the bubble bag does not need to be flattened, the pressure roller 9 can directly fix the bubble bag without having to move along the surface of the bubble bag to flatten it.

[0033] Working principle:

[0034] For this bubble bag cutting device, place the bubble bag on the surface of the workbench 1 and let one side of the bubble bag into the fixing frame. At this time, turn on the electric push rod 2 to drive the pressing plate 3 to move downward, so as to squeeze the bubble bag and thus fix one side of the bubble bag. At this time, push the hinge rod 7 so that one side surface of the hinge rod 7 can abut against the backing plate 13 and rotate by 90 degrees, so that the hinge rod 7 can change from vertically longitudinal to horizontally vertical. And the two hinge rods 7 will synchronously drive the pressure roller 9 to rotate through the connecting block 8. Since the width of the connecting block 8 is the same as the length from the bottom surface of the moving block 6 to the pin shaft, when the hinge rod 7 is horizontally vertical, the pressure roller 9 will abut against the top surface of the workbench 1, so that the pressure roller 9 presses the bubble bag. At this time, insert the first bolt 12 into the threaded holes 11 where two positions on one side surface of the hinge rod 7 and the top surface of the backing plate 13 are aligned, and the position of the pressure roller 9 can be fixed. At this time, turn on the air cylinder 4 to drive the two moving blocks 6 to move through the cross plate 5, so that the pressure roller 9 moves along the surface of the bubble bag, so that the pressure roller 9 can flatten the surface of the bubble bag. When it is flattened and moved to one side of the bubble bag, at the same time insert the second bolt 15 into the screw hole 14 and pass through the screw hole 14 to abut against the pressure roller 9, and let the second bolt 15 continue to move, so as to squeeze the pressure roller 9, thereby restricting the rotation of the pressure roller 9 through the friction of the squeeze, so that the pressure roller 9 can fix the other side of the bubble bag, and let the pressure roller 9 cooperate with the pressing plate 3 to fix the bubble bag, which is convenient for subsequent cutting treatment, reduces the situation that the bubble bag is prone to sliding and offset during the cutting process, and improves the quality of bubble bag cutting production.
