Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a sheet metal edge banding guiding and conveying device. Background Technology

[0002] In the field of sheet metal processing, after the edge banding process is completed, the sheets usually need to be transferred to the next processing stage. Currently, two main transfer methods are used: manual handling and ordinary conveyor belt conveying. Manual handling has significant drawbacks. Operators need to repeatedly bend over to move the sheets, which is not only labor-intensive and inefficient, but also prone to causing the edge banding strip to scratch against hard objects due to improper handling, resulting in surface damage. While ordinary conveyor belt conveying reduces manual labor intensity, the lack of an effective guiding mechanism makes the sheets prone to shifting or tilting during transport, often requiring subsequent secondary positioning and adjustment, severely impacting production efficiency. Furthermore, the adhesive on the edges of newly edge-banded sheets is not yet fully cured, resulting in low bonding strength between the edge banding strip and the substrate. Traditional rigid guiding devices are prone to squeezing and abrading the edge banding strip, affecting the edge banding quality. These problems have not been effectively solved in existing technologies, necessitating the development of a guiding conveyor device that can achieve both efficient transport and protect the edge banding quality. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a board edge banding guiding and conveying device that can improve conveying efficiency, reduce board offset, and protect the surface integrity of the edge banding strip.

[0004] This utility model is implemented using the following method: a sheet metal edge-sealing guiding and conveying device, including an L-shaped support frame. A support plate is provided on the upper surface of the vertical plate of the L-shaped support frame. Multiple rotating rollers are equidistantly arranged on the front of the support plate via bearings. A first strip-shaped groove is provided in the middle of the back of the vertical plate of the L-shaped support frame. A drive motor is embedded in the bottom surface of the first strip-shaped groove. A screw is connected to the output end of the drive motor. A moving block is spirally sleeved on the screw. A lifting plate is provided on the rear surface of the moving block. L-shaped support blocks are provided at both ends of the upper surface of the lifting plate. A limit plate is bolted to the lower surface of the horizontal plate of the L-shaped support block. A fixing block is provided on the inner side of the vertical plate of the L-shaped support block. A support rod is provided between the fixing blocks at both ends. Multiple transfer conveyor belts are equidistantly sleeved on the support rod. The transfer conveyor belts are arranged between pairs of rotating rollers.

[0005] Furthermore, the length of the transfer conveyor belt is longer than that of the rotating drum.

[0006] Furthermore, the vertical plate of the L-shaped support frame has a second strip groove on both the left and right ends on the back side. A guide rod is provided in the second strip groove, and a guide block is sleeved on the guide rod. The guide block is connected to the lifting plate.

[0007] Furthermore, the L-shaped support frames are arranged opposite each other, and the transfer conveyor belts of the L-shaped support frames are arranged in an alternating manner.

[0008] The beneficial effects of this utility model are as follows: This utility model uses a drive motor to drive a screw to adjust the height of the lifting plate, and together with the staggered transfer conveyor belts to form a flexible guiding structure. During the conveying process, the position of the board is automatically corrected, avoiding wear of the edge banding strip caused by rigid contact. At the same time, it reduces manual intervention and has the advantages of improving conveying efficiency, reducing board offset, and protecting the surface integrity of the edge banding strip.

[0010] Figure 2 This is a schematic diagram of the usage state of this utility model. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a sheet metal edge sealing guide conveying device, including an L-shaped support frame 1. A support plate 2 is provided on the upper surface of the vertical plate of the L-shaped support frame 1. Multiple rotating rollers 3 are equidistantly arranged on the front of the support plate 2 via bearings. A first strip groove 11 is provided in the middle of the back of the vertical plate of the L-shaped support frame 1. A drive motor (not shown) is embedded in the bottom surface of the first strip groove 11. The output end of the drive motor is connected to a screw 12. A moving block 13 is spirally sleeved on the screw 12. A lifting plate 4 is provided on the rear surface of the moving block 13. L-shaped support blocks 41 are provided at both ends of the upper surface of the lifting plate 4. A limit plate 42 is bolted to the lower surface of the horizontal plate of the L-shaped support block 41. A fixing block 43 is provided on the inner side of the vertical plate of the L-shaped support block 41. A support rod 44 is provided between the fixing blocks 43 at both ends. Multiple transfer conveyor belts 45 are equidistantly sleeved on the support rod 44. The transfer conveyor belts 45 are arranged between pairs of rotating rollers 3.

[0013] The L-shaped support frame 1 is a load-bearing structure composed of mutually perpendicular vertical and horizontal plates, which can be welded from steel plates and serves as the installation base for the rotating drum and lifting mechanism. The rotating drum 3 is a smooth cylindrical roller, which can be made of aluminum alloy and coated with a rubber layer, used to support the plates and reduce conveying friction. The first strip groove 11 is a rectangular groove extending vertically, which can be formed by milling and serves to accommodate the drive motor and screw assembly. The drive motor is a device capable of outputting rotational power, such as a servo motor or stepper motor, used to drive the screw to rotate for lifting and adjustment. The conveyor belt 45 is a flexible annular belt, for example made of polyurethane material, whose length exceeds that of the rotating drum, forming a guide channel between the rotating drums.

[0014] Specifically, when the drive motor rotates the screw, the moving block moves along the screw's axial direction, thereby raising and lowering the lifting plate and L-shaped support block as a whole. A limiting plate is bolted to the underside of the L-shaped support block's horizontal plate, used to limit the horizontal position of the transfer conveyor belt. Both ends of the support rod are fixed to the fixed block, and multiple transfer conveyor belts are spaced apart along the length of the support rod. When the sheet material enters the rotating drum area, the transfer conveyor belt adjusts to a suitable height according to the sheet material's thickness. The transfer conveyor belts on both sides form a flexible guide surface, and the sheet material is conveyed forward under the combined action of the rotating drum and the transfer conveyor belts. When the transfer conveyor belt contacts the edge of the sheet material, the flexible material buffers the contact pressure, and its continuous rotation reduces sliding friction.

[0015] Compared to existing technologies, traditional fixed guiding devices cannot adapt to plates of different thicknesses, while this solution uses a screw drive to achieve automatic height adjustment of the guiding structure. Ordinary conveyor belts lack guiding function, causing plate misalignment; this solution utilizes a transfer conveyor belt to continuously correct the plate's position during transport. Existing rigid guiding structures are prone to wear on the edge sealing strip; this solution uses a flexible transfer conveyor belt to reduce contact impact, and the transfer conveyor belt moves synchronously with the plate to reduce relative slippage.

[0016] Through the above technical solution, this application achieves automatic guiding function during the sheet material conveying process, avoiding efficiency losses and edge banding damage caused by manual handling. The transfer conveyor belt and rotating roller work together to ensure stable conveying of the sheet material along the predetermined path, reducing secondary positioning operations caused by deviation. The flexible guiding structure disperses pressure through deformation when in contact with the sheet material, effectively protecting the integrity of the edge banding.

[0017] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the length of the transfer conveyor belt 45 is longer than that of the rotating drum 3.

[0018] Among them, the transfer conveyor belt 45 refers to the ring-shaped belt structure used for the edge sealing area of ​​the flexible contact plate. Specifically, it can be made of rubber or polyurethane material, which reduces the rigid impact on the edge sealing strip through elastic deformation.

[0019] The rotating roller 3 refers to the cylindrical rolling component that supports the main body of the sheet material. It can be made of metal or engineering plastic and achieves the translation of the sheet material through rolling friction. The design of the transfer conveyor belt being longer than the rotating roller allows the flexible contact area to extend to the outer edge of the sheet material, expanding the range of non-damaging wrapping of the edge banding strip.

[0020] Specifically, the conveyor belt extends outwards from its installation position between the rotating drums, forming a suspended section that exceeds the axial length of the drums. As the sheet material moves along the rotating drums, its edge-sealing area contacts the suspended section of the conveyor belt, absorbing the lateral pressure generated by the sheet material's displacement through the elastic deformation of the flexible material. Because the contact area between the conveyor belt and the edge-sealing strip increases, the pressure per unit area decreases, preventing localized stress concentration that could lead to deformation or detachment of the edge-sealing strip. Simultaneously, the extended length of the suspended section can cover the edge contour of the sealed sheet material, forming a continuous, flexible guide surface during transport.

[0021] Compared to existing technologies, the guiding structure of ordinary conveyor belts is usually flush with or shorter than the rollers, and can only limit the deviation of the material through rigid baffles. This solution utilizes the length advantage of the transfer conveyor belt to integrate the guiding and conveying functions into the same flexible component, achieving dynamic correction while avoiding rigid contact.

[0022] Through the above technical solution, this application effectively reduces the risk of wear and tear on the edge banding strip during the conveying process, eliminates the problem of edge banding detachment caused by rigid guidance, and maintains the stability of the board conveying by increasing the flexible contact area, thereby reducing the need for manual secondary positioning.

[0023] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the left and right ends of the back of the vertical plate of the L-shaped support frame 1 are provided with a second strip groove 14, a guide rod 15 is provided in the second strip groove 14, a guide block 16 is sleeved on the guide rod 15, and the guide block 16 is connected to the lifting plate 4.

[0024] The second strip groove 14 refers to the strip groove structure opened on the left and right sides of the back of the vertical plate of the L-shaped support frame. It can be formed by mechanical processing and is used to accommodate the guide rod and provide sliding space for the guide block.

[0025] Among them, the guide rod 15 refers to the cylindrical rod fixed in the second strip groove, which can be made of metal and is used to limit the movement trajectory of the lifting plate.

[0026] Among them, the guide block 16 refers to the sliding component sleeved on the guide rod, which can be implemented by a metal block with an inner bearing. The vertical movement of the lifting plate is guided by its cooperation with the guide rod.

[0027] Specifically, a second groove is machined on the left and right sides of the back of the L-shaped support frame vertical plate. The guide rod is installed in the groove by welding or bolting. The guide block is sleeved on the guide rod and connected to the lifting plate by welding or bolting. When the drive motor drives the screw to rotate, the moving block moves along the screw axis, and the lifting plate moves up and down accordingly. At this time, the guide block slides along the guide rod, restricting the lifting plate to move only in the vertical direction, avoiding deviation or jamming caused by uneven force.

[0028] Compared to existing technologies, the lifting mechanisms in existing technologies typically lack a guiding structure, which can easily lead to swaying or deviation during the lifting process, affecting the positioning accuracy of the sheet metal. This solution improves the positioning control capability during sheet metal conveying by adding a cooperating structure of guide rods and guide blocks, making the movement trajectory of the lifting plate more stable.

[0029] Through the above technical solution, this application effectively solves the problem of plate misalignment caused by the lack of guiding function of ordinary conveyor belts. By limiting the movement direction of the lifting plate, the positional accuracy between the transfer conveyor belt and the rotating drum is ensured, and the plate misalignment or friction damage to the edge sealing strip is avoided due to insufficient guidance during the conveying process.

[0030] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, two L-shaped support frames 1 are arranged opposite to each other, and the transfer conveyor belts 45 of the two L-shaped support frames 1 are arranged in an alternating manner.

[0031] The pairing of L-shaped support frames 1 means that two L-shaped support frames are symmetrically arranged on both sides of the sheet material conveying path. This can be achieved by installing the horizontal plates of the two support frames facing inwards, ensuring the sheet material is within the clamping range of the support structures during conveying. The staggered arrangement of the transfer conveyor belts 45 means that the transfer conveyor belts on the two sets of support frames are arranged in a staggered manner in the horizontal or vertical direction. This can be achieved by distributing adjacent transfer conveyor belts at intervals along the conveying direction, allowing the sheet material to be guided alternately by different positions during movement.

[0032] Specifically, when the sheet material enters the conveying area, the opposing L-shaped support frames create a double-sided clamping space, and the edge of the sheet material is wrapped between two rows of transfer conveyor belts. The staggered transfer conveyor belts form alternating contact points in the width direction of the sheet material, and the contact pressure is distributed to different positions on the edge of the sheet material. As the sheet material moves, the staggered transfer conveyor belts form a wave-shaped constraint trajectory on both sides, and the offset trend of the sheet material is corrected by multiple alternating positions. At the same time, the dispersed layout of contact points reduces the wear of the edge banding strip caused by continuous friction at a single position.

[0033] Compared to existing technologies, traditional single-sided guiding structures can only provide unidirectional constraints, and the sheet material is prone to lateral displacement due to inertia during transportation. This solution constructs a closed guiding channel through a double-sided symmetrical layout, while the staggered transfer conveyor belts form a multi-point dynamic correction mechanism. Compared to a single continuous guiding structure, this not only enhances the stability of lateral constraints but also avoids concentrated wear on the edge of the sealing strip at fixed contact points.

[0034] Through the above technical solution, this application solves the problem of plate misalignment caused by the lack of multi-point dynamic guidance in ordinary conveyor belts, reduces the risk of wear caused by continuous friction of the edge banding strip in the same area during the conveying process, and achieves the dual technical effects of stable conveying and edge protection after the plate edge banding.

[0035] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
