Description

Technical Field

[0001] This utility model relates to the field of edge banding equipment technology, specifically to an edge banding strip device. Background Technology

[0002] During the manufacturing process of door sets, edge banding is required on the door panels to make them more aesthetically pleasing and to protect the wood panels.

[0003] T-shaped doors, also known as staggered doors or hidden doors, have stepped edges. Small factories typically use simple semi-automatic edge banding machines to band the door panels. However, during the banding process, manual fixing of the sealing strips is required, which can easily cause wrinkles and injuries to operators. Both sides of the door panel need to be sealed, but the rectangular door panel can collide with surrounding equipment during a 180-degree rotation, which is not conducive to operator work.

[0004] Based on this, the present invention designs a strip sealing device to solve the above problems. Utility Model Content

[0010] The avoidance-type rotating mechanism includes a limiting component, a rotating platform, and a driving component. The limiting component is installed between the base frame and the material placement platform, and is used to allow the material placement platform to move back and forth along the base frame. The rotating platform is rotatably installed in the middle of the material placement platform via bearings.

The lower mounting plate is symmetrically fixedly installed on the left and right sides of the base frame. The guide slide rod is fixedly connected to the lower mounting plate.

[0015] Furthermore, the hot pressing bonding mechanism includes bonding cylinders, angle steel, and heating blocks.

At the same time, the adhesive strip is tightened and fixed, which effectively reduces the possibility of wrinkles in the adhesive strip. The pressure plate fixing mechanism presses the workpiece onto the placement table and positions it. The hot pressing mechanism pushes the adhesive strip to the edge of the workpiece and heats the adhesive strip to complete the edge sealing operation on one side of the workpiece. The drive component drives the workpiece to rotate through the rotary table. At the same time, the drive component causes the placement table to move backward through the limiting component to avoid the related equipment used for edge sealing of the adhesive strip. After the workpiece is rotated 180 degrees, the pressure plate fixing mechanism and the hot pressing mechanism work together to seal the other side of the workpiece. The operator can then perform edge trimming and other operations on the side where the adhesive strip has been applied, which effectively improves the edge sealing efficiency of the workpiece and facilitates the operator's work.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A strip sealing device, comprising a base frame;

[0030] A bracket is fixedly installed at the rear end of the base frame. A hot pressing bonding mechanism and a pressure plate fixing mechanism are respectively provided on the front and rear sides of the top of the bracket. A clamping tensioning mechanism for gripping both ends of the strip is symmetrically provided on the left and right sides of the bracket.

[0031] The front end of the base frame is provided with a clearance-type rotating mechanism. The moving end of the clearance-type rotating mechanism is equipped with a material placement platform for placing workpieces. The clearance-type rotating mechanism is used to drive the clamping tensioning mechanism to rotate in order to adjust the sealing position of the workpiece.

[0032] The avoidance-type rotating mechanism includes a limiting component, a rotating platform, and a driving component. The limiting component is installed between the base frame and the material placement platform, and is used to allow the material placement platform to move back and forth along the base frame. The rotating platform is rotatably installed in the middle of the material placement platform via bearings. The driving component is installed between the base frame and the rotating platform, and is used to control the rotation of the rotating platform and cause the material placement platform to move through the limiting component to achieve avoidance.

[0033] In this invention, the operator first places the workpiece on the placement table, then places the adhesive strip between two clamping and tensioning mechanisms. The two clamping and tensioning mechanisms work together to clamp and tighten the adhesive strip, ensuring accurate positioning and reducing the risk of burns to the operator from the hot-pressing mechanism. Simultaneously, the tightened and fixed adhesive strip effectively reduces the possibility of wrinkles. The pressure plate fixing mechanism presses the workpiece firmly onto the placement table, while the hot-pressing mechanism pushes the adhesive strip towards the edge of the workpiece and heats it, completing the edge sealing operation on one side of the workpiece. Subsequently, the drive assembly rotates the workpiece via a rotary table, while the placement table moves backward via a limiting component to avoid obstructing the equipment used for edge sealing. After the workpiece rotates 180 degrees, the pressure plate fixing mechanism and the hot-pressing mechanism work together to seal the other side of the workpiece. The operator can then perform trimming and other operations on the side where the adhesive strip has been applied, effectively improving the edge sealing efficiency of the workpiece and facilitating the operator's work.

[0034] The limiting assembly includes a lower mounting plate, a guide slide rod, an upper mounting plate, and a spring. The lower mounting plate is symmetrically fixedly installed on the left and right sides of the base frame. The guide slide rod is fixedly connected to the lower mounting plate. The upper mounting plate is fixedly installed at the lower end of the material placement platform. The upper mounting plate is slidably connected to the guide slide rod for limiting. The spring is sleeved on the guide slide rod, and the two ends of the spring abut against the lower mounting plate and the upper mounting plate, respectively.

[0035] The drive assembly includes a rectangular gear ring, a gear, and a servo motor. The rectangular gear ring is fixedly installed at the lower end of the rotary table, the servo motor is fixedly connected to the base frame, and a gear is fixedly installed at the drive end of the servo motor. The gear meshes with the rectangular gear ring.

[0036] The spring and gear are located on the front and rear sides of the material placement platform, respectively.

[0037] In this invention, a spring keeps the rectangular gear ring engaged with the gear. A servo motor drives the rectangular gear ring to rotate, controlling the rotation of the rotary table. As the gear transitions from the long side to the short side of the rectangular gear ring, the center distance between the gear and the rectangular gear ring gradually increases, pushing the placement table to slide backward along the guide slide. This causes the workpiece on the placement table to gradually move backward during rotation, achieving a collision avoidance effect. Conversely, as the gear transitions from the long side to the short side of the rectangular gear ring, the center distance between the gear and the rectangular gear ring gradually decreases, causing the placement table to gradually return to its original position. Ultimately, this achieves the effect of rotating the placement table 180 degrees while maintaining the same position.

[0038] The pressure plate fixing mechanism includes a fixed push cylinder, a pressure block and a rubber pad layer. Multiple fixed push cylinders are provided and evenly distributed at equal intervals along the length of the support. The fixed push cylinders are inclined to the lower side of the rear end of the base frame. The housing of the fixed push cylinder is fixedly connected to the support. The driving end of the fixed push cylinder is fixedly installed with a pressure block. The lower end of the pressure block is provided with a rubber pad layer to increase friction.

[0039] The hot-pressing bonding mechanism includes bonding cylinders, angle steel, and heating blocks. Multiple bonding cylinders are provided and evenly distributed at equal intervals along the length of the support. The bonding cylinders are inclined towards the lower side of the front end of the base frame. The shell of the bonding cylinder is fixedly connected to the support. An angle steel is fixedly installed on the driving end of the bonding cylinder. A heating block is fixedly installed on the inner side of the angle steel.

[0040] The clamping tensioning mechanism includes a mounting plate, a gripper cylinder, a tensioning cylinder, and a pressure sensor. The mounting plate is fixedly connected to the bracket, and the tensioning cylinder is fixedly mounted on the mounting plate. The gripper cylinder is fixedly mounted on the drive end of the tensioning cylinder. The tensioning cylinder is used to control the left and right movement of the gripper cylinder. A pressure sensor is provided between the drive end of the tensioning cylinder and the gripper cylinder. The pressure sensor is used to monitor the tension force of the gripper cylinder on the strip.

[0041] In this invention, the two clamping cylinders on both sides clamp the two ends of the strip, and the tensioning cylinder drives the clamping cylinders to move away from each other to tension the strip. The pressure sensor determines whether the strip is clamped and fixed. The fixing push cylinder drives the pressure block to move obliquely downward to fix the workpiece. The bonding push cylinder drives the angle steel to move obliquely downward to push the strip towards the T-shaped edge of the workpiece until the strip is tightly bonded to the T-shaped edge of the workpiece. Under the heating of the heating block, the workpiece is automatically sealed.

[0042] The upper end of the material placement platform is also equipped with a vacuum suction cup, which is used to adsorb the workpiece on the material placement platform to achieve the effect of fixing the workpiece and prevent the position of the workpiece on the material placement platform from shifting during the movement of the material placement platform, thus affecting the edge sealing effect; although the illustration is omitted, the lower end of the base frame is equipped with a vacuum generator, and the lower end of the vacuum suction cup is connected to the vacuum generator through a pipe to achieve the vacuum adsorption effect.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
