Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box processing, and in particular to a cardboard box folding device for cardboard box production and processing. Background Technology

[0002] Carton creases are pre-set fold lines created on cardboard during carton processing through mechanical pressing or die indentation. They are a key structural element in carton forming. Their function is to guide precise folding of the carton, ensuring a stable structure and neat edges after forming, and preventing the cardboard from cracking or deforming during folding.

[0003] The existing announcement number is CN222972881U, which discloses a cardboard box folding device for cardboard box production and processing. It includes: a frame, two rollers mounted on the frame, two conveyor belts mounted on the rollers, a creasing belt mounted on the conveyor belts, and four limiting rings mounted on the rollers, respectively installed on both sides of the two conveyor belts. The lateral position of the conveyor belts and the creasing belts is adjusted by the limiting rings. This cardboard box folding device for cardboard box production and processing, by setting up a frame and rollers, and installing two conveyor belts on the two rollers, utilizes the limiting rings installed on both sides of the conveyor belts to easily adjust the lateral position of the creasing belt. After adjustment, the creasing belt can cooperate with the two pressure rollers above the pressure rollers, preventing inconsistent or mismatched creasing positions on the upper and lower surfaces of the cardboard box.

[0004] While the aforementioned issues can be addressed by using a creasing tape in conjunction with rollers to creasing both the top and bottom of the carton, the fixed thickness of the creasing tape means that for relatively thin cartons, the thicker, raised portion of the tape can exert excessive pressure on the bottom during creasing. This can result in excessively deep creasing, exceeding the carton's deformation tolerance. Conversely, for relatively thick cartons, the creasing tape provides insufficient support and depth of pressure on the bottom when used with rollers. This leads to shallow, blurry creasing that fails to create clear and regular crease lines. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cardboard box folding device for cardboard box production and processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cardboard box folding device for cardboard box production and processing includes a worktable with multiple sets of rods rotatably connected to it. Each set of rods is connected to two sets of rollers. A groove is opened at one end and the other end of the worktable, and the multiple sets of rollers are respectively connected to the corresponding grooves. An opening is opened on the worktable. A double-threaded rod is rotatably connected to the worktable, and the double-threaded rod is threaded to two sets of plates. A frame is connected to the worktable, and an electric push rod is installed at one end of the frame. A connector, a second double-threaded rod, two sets of blocks, and two sets of pressure rollers are provided above the worktable.

[0007] Preferably, the output end of the electric push rod is connected to the connecting piece, the connecting piece is rotatably connected to the double-threaded rod, the double-threaded rod is threadedly connected to two sets of blocks, and the two sets of blocks are rotatably connected to the corresponding pressure rollers.

[0008] Preferably, the highest points of the two sets of plates and the highest points of the multiple sets of rollers are located on the same horizontal line, and one end of the two sets of plates is trapezoidal.

[0009] Preferably, a sliding groove is provided at one end of the frame, and two parts of the double-ended threaded rod are located within the sliding groove.

[0010] Preferably, both the first and second double-threaded rods are connected to a handwheel at one end.

[0011] Preferably, one end of the frame is provided with multiple sets of scales, and one end of the workbench is provided with multiple sets of scales.

[0012] Preferably, one end of the connector is connected to a round rod 1 through the other end, and both sets of round rod 1 are slidably connected to the two sets of blocks. The workbench is connected to two sets of round rod 2 through the other end, and both sets of round rod 2 are slidably connected to the two sets of plates.

[0013] The beneficial effects of this utility model are as follows: 1. Through the coordination of the electric push rod, pressure roller, and board, an external device moves the carton. Activating the electric push rod moves the connecting piece downwards, which in turn moves the pressure roller downwards to crease the carton against the board. Because the highest point of the roller is on the same horizontal line as the top surface of the board, and the board's position remains relatively fixed without rotating the double-threaded rod, operators can adjust the distance between the pressure roller and the board to crease cartons of varying thicknesses. For thinner cartons, the distance between the pressure roller and the board can be reduced, ensuring the pressure applied by the roller is applied directly to the carton surface, creating clear creases without causing wrinkles, tears, or damage to the carton edges due to excessive pressure. For thicker cartons, increasing the distance between the pressure roller and the board ensures sufficient space for the roller to fully compress the carton. During the downward movement of the pressure roller, it can exert an effective force on the hard material of the thick cardboard box. Combined with the stable support of the board, it can make the indentation depth reach the ideal state, avoiding problems such as shallow and blurry indentations and irregular crease tracks caused by insufficient pressure. It has a wide range of applications to a certain extent. 2. Through the cooperation between the double-ended threaded rod one, double-ended threaded rod two, and the board body, rotating double-ended threaded rod one moves the board body. When processing cartons of different specifications, according to the creasing position parameters required for folding the cartons, the operator only needs to rotate double-ended threaded rod one to drive the board body to the target position, thus forming a crease at the designated position on the bottom of the carton. Whether it's a crease on the edge of the carton or a dividing crease in the middle area, it can be achieved by adjusting the position of the board body. Rotating double-ended threaded rod two can drive the pressure roller to adjust its position, working in synergy with the adjustment of the board body. When creasing is needed at different positions on the top surface of the carton, the operator rotates double-ended threaded rod two, which drives the block to move through the threaded transmission. The block then drives the pressure roller to move along the circular rod one, moving the pressure roller to the corresponding position on the top surface of the carton. This method has a wide range of applications. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figures 1 to 5 A cardboard box folding device for cardboard box production and processing includes a worktable 1, with multiple sets of rods 2 rotatably connected to the worktable 1. An external device pushes the cardboard box to slide on a plate 7 and multiple sets of rollers 3. The external device can be a hydraulic cylinder with a push plate. The hydraulic cylinder drives the push plate to move, and the push plate contacts the cardboard box to push it. The device has a simple structure, adjustable thrust, and can avoid damage to the cardboard box to a certain extent. Each set of rods 2 is connected to two sets of rollers 3. Grooves 4 are opened at one and the other ends of the worktable 1, and the multiple sets of rollers 3 are respectively placed within the corresponding grooves 4. The worktable 1 has an opening 5. The worktable 1 rotates... A double-threaded rod 6 is connected to two sets of plates 7. A frame 8 is connected to the workbench 1, and an electric push rod 9 is installed at one end of the frame 8. Above the workbench 1 are a connector 10, a second double-threaded rod 11, two sets of blocks 12, and two sets of pressure rollers 13. When the electric push rod 9 is activated, it moves the blocks 12 downward through the connector 10 and the second double-threaded rod 11. The blocks 12 then move the pressure rollers 13 downward. The highest point of the roller 3 is on the same horizontal line as the top surface of the plate 7, and the position of the plate 7 remains relatively fixed without rotating the double-threaded rod 6. The operator only needs to adjust the distance between the pressure rollers 13 and the plates 7 using the electric push rod 9 to perform creasing processing on cartons of different thicknesses to a certain extent.

[0018] In this embodiment, the output end of the electric push rod 9 is connected to the connector 10, and the connector 10 is rotatably connected to the double-threaded rod 11. The double-threaded rod 11 is threadedly connected to two sets of blocks 12, and the two sets of blocks 12 are rotatably connected to the corresponding pressure rollers 13. Rotating the double-threaded rod 6 moves the plate 7 to adjust the bottom indentation position, and rotating the double-threaded rod 11 moves the block 12, which in turn moves the pressure roller 13 to adjust the top indentation position. This design has a wide range of applicability. The highest points of the two sets of plates 7 and the highest points of the multiple sets of rollers 3 are on the same horizontal line. During indentation, the pressure roller 13 presses the carton downwards, and the plate 7 acts as a bottom support structure in conjunction with the pressure roller 13. This keeps the carton flat in the indentation area and ensures that the pressure applied by the pressure roller 13 is evenly applied to the surface of the carton, thereby forming a crease. One end of each set of plates 7 is trapezoidal. For fragile materials such as thin cartons, the right-angled ends may cause edge tearing or deformation upon contact. The trapezoidal design, through a gentle transition structure, reduces the contact stress between the carton and the end of the board 7. A groove 14 is provided at one end of the frame 8, and a portion of the double-threaded rod 11 is located within the groove 14. The spatial design of the groove 14 provides ample space for the vertical displacement of the double-threaded rod 11, ensuring that the height adjustment process is not obstructed by the structure to a certain extent. Both the first and second double-threaded rods 11 are connected to a handwheel 15 at one end, making it easier to rotate them. Multiple sets of scales 17 are provided at one end of the frame 8, and multiple sets of scales 18 are provided at one end of the worktable 1. The board 7 moves with reference to scales 18, and the pressure roller 13 moves with reference to scales 17, facilitating alignment and preventing inconsistent indentation positions on the upper and lower parts of the carton. One end of the connector 10 is connected to a round rod 16, and both sets of round rods 16 are slidably connected to the two sets of blocks 12. The round rods 16 guide the movement of the blocks 12. The worktable 1 is connected to two sets of round rods 19, and both sets of round rods 19 are slidably connected to the two sets of plates 7. The round rods 19 guide the movement of the plates 7.

[0019] The working principle of this embodiment is as follows: Before starting the device, the operator needs to make preliminary adjustments according to the thickness of the carton to be processed and the required indentation position. By rotating the handwheel 15 at the end of the double-threaded rod 6, the two sets of plates 7 are driven to slide along the round rod 19 using the threaded transmission. Combined with the scale 18 on the worktable 1, the plates 7 are moved to the preset indentation position at the bottom of the carton. At the same time, rotating the handwheel 15 at the end of the double-threaded rod 11 drives the two sets of blocks 12 to slide along the round rod 16, driving the pressure roller 13 to move. Referring to the scale 17 on the frame 8, the pressure roller 13 is aligned with the plates 7 in the horizontal direction to ensure the indentation position corresponds. The external drive device drives the rod 2 to rotate, and the rod 2 drives the roller 3 to rotate synchronously in the groove 4. The operator places the carton to be processed on the roller 3, and the roller 3 moves the carton along the surface of the worktable 1 through friction. According to the thickness of the carton, the height of the connecting piece 10 is adjusted by the electric push rod 9, thereby changing the vertical distance between the pressure roller 13 and the plates 7. For thin cartons, reduce the spacing to avoid edge wrinkles and damage; for thick cartons, increase the spacing to ensure sufficient compression to form clear creases. Since the highest point of roller 3 is flush with the top surface of plate 7, the cartons remain horizontal during transport, ensuring crease stability. Electric push rod 9 pushes connector 10 downwards, and double-headed threaded rod 11 moves synchronously downwards along the slide groove 14 of frame 8, driving pressure roller 13 to press against the carton surface. Pressure roller 13, in conjunction with plate 7, applies vertical compression to the carton, pressing creases at preset positions.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
