Description

Technical Field

[0001] This application relates to the field of cardboard gluing, and more particularly to a plasma gluing machine. Background Technology

[0002] Gluing machines are key auxiliary equipment in the production processes of cartons, leather goods, and footwear, used for the gluing process in the bonding step.

[0003] Currently, Chinese utility model patent CN207345148U discloses a cardboard gluing machine, including a glue tank and a cardboard conveying mechanism. A lower gluing roller and an upper gluing roller are installed inside the glue tank, and the upper and lower gluing rollers are pressed together. The lower gluing roller is connected to a drive mechanism that drives its rotation. An outer guide roller and an inner guide roller are installed outside the glue tank. The right guide roller extends beyond the edge of the glue tank, and the outer guide roller extends beyond the inner guide roller. This utility model improves the uniformity of gluing on cardboard.

[0004] The glue adheres to the cardboard through a mechanical interlocking action. However, as the quality of cardboard has gradually improved, the overall smoothness of the cardboard has greatly increased, resulting in insufficient roughness on the bonding surface. This weakens the mechanical interlocking action of the glue, leading to a decrease in bonding strength. Summary of the Invention

[0005] In order to improve the mechanical interlocking effect between the glue and the cardboard, thereby increasing the bonding strength, this application provides a plasma gluing machine.

[0006] This application provides a plasma coating machine, which adopts the following technical solution: A plasma gluing machine includes a gluing frame, a feeding assembly, a conveying assembly, a gluing component, and a plasma treatment unit. The feeding assembly is located at the feed end of the gluing frame and is used to stack cardboard. The conveying assembly is used to sequentially feed the cardboard from the feeding assembly into the gluing frame. The plasma treatment unit includes a mounting plate, a plasma emitter, and a power supply device. The mounting plate is disposed on the gluing frame, and the plasma emitter is disposed on the mounting plate, facing the bonding area of ​​the cardboard. The power supply device is used to supply power to the plasma emitter. The gluing assembly is disposed on the gluing frame and is used to apply glue to the bonding area of ​​the cardboard after plasma treatment.

[0007] By adopting the above technical solution, and by setting up a plasma treatment component, the plasma emitter is used to treat the bonding area of ​​the cardboard, which can effectively increase the surface roughness and activity of the cardboard, solve the problem of weakened mechanical interlocking effect of glue due to the smoothness of the cardboard, and significantly improve the bonding strength. The feeding component is used to stack the cardboard, and the conveying component is used to send the cardboard to the gluing component. The coordinated operation of the feeding component, conveying component, and gluing component realizes the processing of cardboard from feeding, conveying, plasma treatment to gluing.

[0008] Optionally, the gluing assembly includes a gluing roller, a pressure roller, and a glue container. The glue container is disposed on the mounting plate and contains glue. The gluing roller is rotatably connected to the glue container and is used to abut against the bonding area of ​​the paperboard after plasma treatment. The pressure roller is rotatably connected to the glue container and abuts against the side wall of the paperboard away from the bonding area.

[0009] By adopting the above technical solution, the gluing roller is immersed in the glue tank to take glue and abut against the bonding area of ​​the cardboard, so that the glue can be evenly applied; the pressure roller abuts against the non-bonding surface of the cardboard, and the pressure makes the glue in close contact with the surface of the cardboard, avoiding the cardboard from shifting during the glue application process, ensuring the uniformity of glue application and bonding effect, further increasing the effect of glue adhering to the cardboard, thereby improving the bonding quality of the cardboard splicing.

[0010] Optionally, the gluing frame is further provided with an auxiliary pressing assembly, which includes an auxiliary frame, an auxiliary cylinder, and several auxiliary rollers. The auxiliary frame is slidably connected to the gluing frame in a vertical direction, the auxiliary rollers are evenly distributed on the auxiliary frame, and the auxiliary rollers are rotatably connected to the auxiliary frame. The auxiliary cylinder is used to drive the auxiliary frame to move and make the auxiliary rollers abut against the cardboard.

[0011] By adopting the above technical solution, the auxiliary pressing component drives the auxiliary frame to move up and down through the auxiliary cylinder, so that the auxiliary roller abuts against the cardboard and applies pressure to the cardboard during the conveying process to prevent the cardboard from warping or shaking, ensuring that the cardboard is in a stable position during plasma treatment and gluing, and improving process accuracy and product consistency.

[0012] Optionally, the feeding assembly includes a feeding platform and a restrictor for organizing the material. The feeding platform is located at the feeding end of the gluing frame. The restrictor includes two restricting plates and a bidirectional screw. The two restricting plates are distributed along both sides of the cardboard. The restricting plates are slidably connected to the feeding platform along the distribution direction of the two restricting plates. The bidirectional screw is rotatably connected to the feeding platform. The two restricting plates are respectively threaded to the two ends of the bidirectional screw with opposite rotation directions.

[0013] By adopting the above technical solution, the limiting component of the feeding assembly drives the two limiting plates to move synchronously through a bidirectional screw. The spacing can be adjusted according to the size of the cardboard, which can neatly stack the cardboard, prevent the cardboard from tilting during feeding, improve feeding accuracy and feeding efficiency, and reduce production failures caused by material deviation.

[0014] Optionally, the feeding assembly further includes a blocking component, which includes a blocking frame, several blocking strips, and an adjusting screw. The blocking frame is slidably connected to the feeding platform in a vertical direction. The several blocking strips are vertically arranged and distributed horizontally perpendicular to the transport direction of the cardboard. The blocking strips are set on the blocking frame. The gap between the lower end of the blocking strip and the conveying assembly allows the bottommost cardboard in the stacked cardboard to pass through. The adjusting screw is vertically arranged and rotatably connected to the feeding platform. The adjusting screw is threadedly connected to the blocking frame.

[0015] By adopting the above technical solution, the blocking strip of the blocking component forms a gap with the conveying assembly, allowing only the bottommost cardboard to pass through. The height of the blocking strip can be adjusted with the adjusting screw to accommodate cardboard stacks of different thicknesses, preventing multiple cardboard sheets from being fed out at the same time, ensuring the continuity and accuracy of feeding, and improving the stability of the equipment.

[0016] Optionally, the discharge end of the gluing frame is provided with a post-processing assembly. The post-processing assembly includes a discharge table, a transfer component, a drive component, and three processing tables for folding and stacking. The three processing tables are distributed along the transport direction of the cardboard. The processing tables are located on one side of the discharge table. The transfer component is used to transport the glued cardboard to the discharge table. The transfer component includes a transfer frame, several transfer rollers, and a transfer motor. The transfer frame is slidably connected to the discharge table in the vertical direction. The transfer rollers are rotatably connected to the transfer frame. The transfer motor is used to drive the transfer rollers to rotate. The drive component is used to drive the transfer frame to lift, so that the cardboard is separated from the transfer component and sent to the processing table.

[0017] By adopting the above technical solution, the transfer frame is lifted by the drive component, so that the cardboard is separated from the conveying assembly and transferred to the processing table to realize the output of the cardboard; the three processing tables are distributed along the transport direction, and can sequentially complete the post-processing processes such as folding and stacking of the cardboard, thereby optimizing the production process and improving production efficiency.

[0018] Optionally, a folding assembly and a stacking assembly are sequentially arranged on the processing table. The folding assembly includes a fixed plate, two folding plates, and two folding drive components. The fixed plate is disposed on the processing table, and the two folding plates are respectively located on opposite sides of the first plate. The folding plates are rotatably connected to the fixed plate. The two folding drive components correspond to the two folding plates. Each folding drive component includes a drive gear, a drive motor, and a fixed gear. The fixed gear is coaxial with the rotation axis of the folding plate and is disposed on the fixed plate. The drive gear is rotatably connected to the folding plate and meshes with the fixed gear. The drive motor is used to drive the drive gear to rotate.

[0019] By adopting the above technical solution, the cardboard is moved to the folding device by the drive assembly. At this time, the folding drive component is driven in sequence. The active motor drives the active gear to rotate, and the active gear drives the folding plate to rotate around the axis of the fixed plate, so that the cardboard is folded. The cardboard is folded by the two folding plates, and the glued parts of the cardboard are bonded. The cooperation between the fixed plate and the two folding plates on both sides can adapt to different folding requirements and ensure that the folded cardboard structure meets the process requirements.

[0020] Optionally, the stacking assembly includes a stacking frame, a lifting frame, a translation frame, a lifting cylinder, a linear motor, and an adsorption component. The stacking frame is disposed on the processing table. The lifting frame is slidably connected to the stacking frame in the vertical direction. The lifting cylinder is used to drive the lifting frame to move. The translation frame is slidably connected to the lifting frame in the horizontal direction. The length direction of the linear motor is parallel to the sliding direction of the translation frame. The linear motor is disposed on the lifting frame. The output end of the linear motor is disposed on the translation frame. The adsorption component is disposed on the lifting frame and is used to adsorb the folded cardboard.

[0021] By adopting the above technical solution, the stacking component uses a lifting cylinder to move the lifting frame up and down, and a linear motor to drive the translation frame to slide horizontally. Together with the adsorption component, it adsorbs the folded cardboard, thus realizing the automatic stacking of cardboard. The stacking frame makes the cardboard stacked neatly, reduces manual intervention, and improves stacking efficiency and automation level.

[0022] Optionally, the adsorption component includes a plurality of adsorption suction cups, a negative pressure pump, and a plurality of connecting pipes. The plurality of adsorption suction cups are evenly distributed on the translation frame. The adsorption suction cups are disposed on the translation frame. The negative pressure pump is disposed on the translation frame. One end of the plurality of connecting pipes is disposed on the adsorption suction cups, and the other end of the connecting pipes is disposed on the negative pressure end of the negative pressure pump.

[0023] By adopting the above technical solution, the suction cups of the adsorption component are connected to the negative pressure pump through the connecting pipe. The negative pressure adsorbs the cardboard, and the adsorption force is uniform and stable, which can prevent the cardboard from falling off during the transfer process. Multiple suction cups are evenly distributed on the translation frame to adapt to the adsorption needs of cardboard of different sizes and ensure the reliability of the stacking action.

[0024] Optionally, the processing table is further provided with a clamping component, which includes a clamping cylinder and a clamping plate. The clamping cylinder is vertically arranged, and the cylinder body of the clamping cylinder is disposed on the processing table. The clamping plate is disposed on the piston rod of the clamping cylinder, and the clamping plate is used to clamp the stacked cardboard.

[0025] By adopting the above technical solution, the pressing cylinder of the pressing component drives the pressing plate to move downward, applying pressure to the stacked cardboard, making the cardboard stacked tightly, making the adhesive joints of the cardboard tighter, reducing the possibility of subsequent peeling, facilitating subsequent storage or transportation, and ensuring that the stacked cardboard has uniform dimensions, thus improving product quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Plasma treatment before gluing roughens the surface of the cardboard, improves the mechanical interlocking effect of the glue, and thus increases the bonding strength of the cardboard. 2. The limiting components on the loading platform are used to organize the stacked cardboard so that the cardboard can be fed into the gluing component in sequence; 3. The post-processing component is used to fold and stack the glued cardboard. Folding allows the cardboard to be glued quickly, improving the bonding effect. Stacking further reduces the space occupied by the cardboard, making it easier for subsequent transportation and storage. Attached Figure Description
