Description

Technical Field

[0001] This utility model relates to the field of drying technology for cardboard laminating machines, and in particular to a drying mechanism for a cardboard laminating machine. Background Technology

[0002] The drying mechanism of a cardboard laminating machine is a key piece of equipment in the cardboard laminating production process. It is used to quickly dry and cure the laminated cardboard, so that the decorative paper and the cardboard are firmly bonded together.

[0003] Traditional drying mechanisms typically employ a single or double-unit dryer design with fixed spacing, using hot air circulation or radiant heating to cure the adhesive. This structure has significant limitations: First, the fixed spacing restricts the drying range, making it difficult to adapt to the production needs of cardboard of different widths. When the cardboard is narrow, excess heat can easily cause localized overheating, while when the cardboard is wide, there will be blind spots in the drying process, making it difficult to balance production efficiency and product quality. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a drying mechanism for a cardboard laminating machine, which solves the problem of poor adaptability of existing fixed drying equipment due to its inability to adapt to cardboard of different widths, resulting in localized insufficient or excessive drying.

[0005] This utility model also provides a drying mechanism for a cardboard laminating machine, comprising: a base plate, an electric conveyor belt on the inner surface of the base plate, a frame fixedly connected to the upper surface of the base plate, a sliding assembly on the frame, a turntable rotatably connected to the inner surface of the sliding assembly, four sliders slidably connected to the inner surface of the turntable, a dryer assembly connected to the lower surface of the four sliders via a connecting frame, a traction assembly on the turntable, and the four sliders being driven by the traction assembly.

[0006] According to the present invention, a drying mechanism for a cardboard laminating machine is provided on the turntable, and the slider is slidably connected inside the slide groove.

[0007] According to the present invention, a drying mechanism for a cardboard laminating machine includes a sliding assembly comprising a slide table and a lead screw. The slide table is slidably connected to the inner surface of a frame, the turntable is rotatably connected to the inner surface of the slide table, and the lead screw is rotatably connected to the inner surface of the frame. The slide table and the lead screw are connected by a through thread. A motor is fixedly connected to the side surface of the frame, and the lead screw is driven by the motor.

[0008] According to the present invention, a drying mechanism for a cardboard laminating machine includes a dryer assembly comprising: a fan cover, a second motor, fan blades, and a heating plate. The fan cover is fixedly connected to the lower surface of a connecting frame, the second motor is embedded in the upper surface of the fan cover, the fan blades are fixedly connected to the output end of the second motor, and the heating plate is fixedly connected to the inner wall of the fan cover.

[0009] According to the present invention, a drying mechanism for a cardboard laminating machine includes a traction component comprising a traction frame and a traction rod. The traction frame is rotatably connected to the lower surface of the turntable, the traction rod is fixedly connected to the lower surface of the slider, and the traction rod is slidably connected inside the traction frame. The traction frame is arc-shaped.

[0010] According to the drying mechanism of the cardboard laminating machine of this utility model, a motor is fixedly connected to the upper surface of the slide table, and the turntable is driven by the motor.

[0011] Beneficial effects:

[0012] The drying mechanism of the cardboard laminating machine in this technical solution can provide a larger drying range through four drying components. The distance between the four drying components can be flexibly controlled through the traction component, which can quickly adapt to different cardboard widths (such as narrow to wide boards). This avoids insufficient or excessive drying in some areas due to fixed spacing. Reducing the spacing can enhance the local drying intensity (such as cardboard edges or areas with thick glue coating), while increasing the spacing is suitable for homogenized large-area drying.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1 , Figure 3 , Figure 4 This utility model embodiment provides a drying mechanism for a cardboard laminating machine, which includes: a base plate 3, an electric conveyor belt 2 on the inner surface of the base plate 3, and a frame 1 fixedly connected to the upper surface of the base plate 3. Considering the low flexibility of traditional drying mechanisms, a sliding component is provided on the frame 1 to drive the slide table 4 to move, thereby driving the dryer components to move. A turntable 7 is rotatably connected to the inner surface of the sliding component to drive the four dryer components to rotate.

[0023] Considering the need to precisely control the spacing between the four dryers to match the width of the cardboard, four sliders 6 are slidably connected to the inner surface of the turntable 7. The turntable 7 is provided with a slide groove 13, and the sliders 6 are slidably connected inside the slide groove 13. The lower surfaces of the four sliders 6 are connected to the dryer components through the connecting frame 15.

[0024] Considering the need to achieve coordinated adjustment of the spacing between the four dryers through a mechanical structure to avoid the inefficiency of manual adjustment, a traction assembly is installed on the turntable 7. The four sliders 6 are driven by the traction assembly, which includes a traction frame 14 and a traction rod 12. The traction frame 14 is rotatably connected to the lower surface of the turntable 7, and the traction rod 12 is fixedly connected to the lower surface of the sliders 6. The traction rod 12 is slidably connected inside the traction frame 14. The traction frame 14 is arc-shaped. When the traction frame 14 rotates, the traction rod 12 (fixedly connected to the sliders 6) inside it is pulled synchronously, so that the four sliders 6 slide in conjunction within the slide groove 13 to achieve synchronized spacing adjustment.

[0025] In summary, the improvement of this embodiment lies in:

[0026] The four dryer components provide a larger drying range, and the traction component allows for flexible control of the distance between the four dryer components. This enables quick adaptation to different cardboard widths (such as from narrow to wide boards), avoiding under-drying or over-drying of certain areas due to fixed spacing. Reducing the spacing can enhance local drying intensity (such as cardboard edges or areas with thick glue coating), while increasing the spacing is suitable for homogenized large-area drying.

[0027] Based on the above, other structures also need to be disclosed in detail, such as:

[0028] Reference Figure 1 , Figure 5 Considering the need to provide stable support and a base for movement for the dryer components, the sliding assembly includes: a slide table 4 and a lead screw 16. The slide table 4 is slidably connected to the inner surface of the frame 1, the turntable 7 is rotatably connected to the inner surface of the slide table 4, and the lead screw 16 is rotatably connected to the inner surface of the frame 1. The slide table 4 and the lead screw 16 are connected by a threaded connection. A motor 17 is fixedly connected to the side surface of the frame 1. The lead screw 16 is driven by the motor 17. The motor 17 drives the lead screw 16 to rotate, which in turn drives the slide table 4, on which the dryer components are mounted, to move.

[0029] Reference Figure 3 The dryer components include: a fan cover 9, a second motor 8, a fan blade 10, and a heating plate 11. The fan cover 9 is fixedly connected to the lower surface of the connecting frame 15, the second motor 8 is embedded in the upper surface of the fan cover 9, the fan blade 10 is fixedly connected to the output end of the second motor 8, and the heating plate 11 is fixedly connected to the inner wall of the fan cover 9.

[0030] Reference Figure 1 The upper surface of the slide table 4 is fixedly connected to the motor 5, and the turntable 7 is driven by the motor 5.

[0031] Working principle: First, the veneer paperboard to be dried is conveyed forward by the electric conveyor belt 2 on the inner surface of the base plate 3. When the paperboard enters the drying area, the motor 5 starts and drives the turntable 7 to rotate. The rotation of the turntable 7 adjusts the overall position of the four dryer components so that the hot air can cover the surface of the paperboard in the best position.

[0032] At the same time, motor 317 drives lead screw 16 to rotate. Through the threaded engagement between lead screw 16 and slide table 4, slide table 4 is pushed to slide laterally within frame 1, thereby driving the entire turntable 7 and the four dryer components to move laterally and adjust the drying position.

[0033] When it is necessary to adjust the dryer spacing, manually rotate the traction frame 14, and the traction rod 12 (fixed connection slider 6) inside it is pulled synchronously, so that the four sliders 6 slide in the slide groove 13 of the turntable 7, thereby changing the lateral spacing between the four dryer components, accurately matching the width of the cardboard. For the edge of the cardboard or the area with thick glue coating, the spacing can be reduced to enhance the local drying intensity, while for large areas, the spacing can be expanded to achieve homogeneous drying.

[0034] Each dryer component is connected to the slider 6 via the connecting frame 15. The motor 8 inside the fan cover 9 drives the fan blades 10 to rotate, blowing the heat generated by the heating plate 11 onto the surface of the cardboard through the fan cover 9, forming forced hot air, accelerating the curing of the adhesive, and finally completing the drying process of the cardboard lamination, achieving efficient, uniform and precise drying effect, and adapting to the production needs of cardboard of different specifications.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
