Detailed Implementation

[0019] 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.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0022] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1-2 As shown, the strip cardboard edge gluing device in this embodiment includes a frame 1, a worktable 2, a glue tank 3, a gluing roller 4, a pressure roller 5, a drive mechanism 6, a guide plate 7, a glue tank 8, and a pressing assembly 9.

[0024] The workbench 2 is set horizontally on the frame 1. A clearance groove 21 is provided on the horizontal part of the workbench 2. The function of the clearance groove 21 is to allow the glued part to be avoided after the cardboard is coated with glue, so as to prevent the glue from scratching the workbench surface.

[0025] The glue tank 3 is located on the bottom side of the clearance groove 21. The glue bucket 8 is set on the workbench 2 via the bracket 81. The bottom of the glue bucket 8 is connected to the glue tank 3 via the hose 82. Glue is added into the glue tank 3 through the glue bucket 8 and the hose 82 for adhering to the glue roller 4.

[0026] The glue-applying roller 4 is rotatably positioned inside the glue tank 3, and the pressure roller 5 is rotatably positioned above the glue-applying roller 4 and above the worktable. During the rotation of the glue-applying roller 4, the glue in the glue tank 3 is adhered to the surface, and then the glue is applied to the cardboard under the joint clamping of the pressure roller 5 and the glue-applying roller 4.

[0027] The drive mechanism 6 is located inside the frame 1 and is connected to the glue-applying roller 4. The guide plate 7 is arranged horizontally on the worktable and is located on the side opposite to the clearance groove 21.

[0028] The drive mechanism 6 includes a drive motor 61, a first sprocket 62, a second sprocket 63, and a chain 64. The drive motor 61 is fixedly installed inside the frame 1. The first sprocket 62 is coaxially mounted on the main shaft of the drive motor 61. The second sprocket 63 is coaxially mounted with the glue roller 4 and located outside the glue tank 3. The two ends of the chain 64 are respectively connected to the first sprocket 62 and the second sprocket 63 for transmission.

[0029] The drive motor 61 drives the first sprocket 62 to rotate, and drives the second sprocket 63 to rotate via the chain 64, which in turn drives the coating roller 4 to rotate.

[0030] The pressure roller 5 is mounted on the worktable 1 via the pressing assembly 9, such as... Figure 3 As shown, the clamping assembly 9 includes a vertical rod 91, a horizontal rod 92, a swing rod 93, a compression spring 94, a nut 95, and an adjusting bolt 96. The bottom of the vertical rod 91 is fixedly set on the top of the glue groove 3. One end of the horizontal rod 92 is fixedly connected to the top of the vertical rod 91. An adjusting groove 921 is provided on the horizontal rod 92. One end of the swing rod 93 is rotatably connected to the vertical rod 91, and the other end is rotatably connected to the pressure roller 5 through a rotating shaft 97. The adjusting bolt 96 passes through the adjusting groove 921 longitudinally. The nut 95 is set on the upper side of the horizontal rod 92 and connected to the adjusting bolt 96. A limiting rod 931 is also provided on the upper side of the swing rod 93 at a position corresponding to the adjusting bolt 96. The upper end of the compression spring 94 is fixedly connected to the bottom of the adjusting bolt 96, and the lower end is sleeved on the outside of the limiting rod 93.

[0031] like Figure 4 As shown, the frame 1 is also provided with an adjustment mechanism 10. The adjustment mechanism 10 includes an adjustment seat 101, a screw 102 and a slide rail 103. The adjustment seat 101 is located at the bottom of the glue tank 3. The screw 102 is located at the bottom of the glue tank 3 and is connected to the adjustment seat 101 by a threaded transmission. The slide rail 103 is fixedly located inside the frame 1 and is slidably connected to the bottom of the adjustment seat 101.

[0032] The main shaft of the drive motor 61 is slidably connected to the first sprocket 62 via a key block 65, and an adjustment handle 104 is also provided at the end of the screw 102 located on the outside of the frame 1.

[0033] By turning the adjusting handle 104, the screw 102 is rotated, which in turn moves the adjusting seat 101 along the slide rail 103, causing the glue tank 3 and the glue application roller 4 to move as a whole. This changes the position of the glue application roller 4 relative to the guide plate 7, that is, the length of the glue application roller 4 extending beyond the guide plate 7, thereby changing the glue application width. During the adjustment process, the position of the second sprocket 63 also changes simultaneously. The chain 64 can drive the first sprocket 62 to slide back and forth along the main shaft and key block 65, thereby changing the position of the first sprocket 62.

[0034] When using this utility model, the worker will press one side of the long strip of cardboard against the guide plate 7 and feed it to the glue roller 4 so that it enters between the glue roller 4 and the pressure roller 5. The drive mechanism 6 drives the glue roller 4 to rotate, so that the glue in the glue tank 3 is stuck to the outer wall of the glue roller 4 and coated on the edge of the cardboard. At the same time, the cardboard is conveyed.

[0035] This invention enables continuous gluing of long strips of cardboard, without being limited by the length or width of the cardboard, thus improving the flexibility and versatility of the device.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
