Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to a belt pressing device for edge banding machines. Background Art

[0002] In current edge banding machines, adhesive application to the edge banding is typically done with a static pressure plate mounted on one side of the edge banding. This platen, working in conjunction with a heated adhesive pot, clamps and guides the edge banding, ensuring even application of the adhesive.

[0003] However, this design has a significant drawback: since the pressure plate is fixed and close to the melt glue pot, and the melt glue pot maintains an extremely high temperature during operation, it is inevitable that the pressure plate will be exposed to a high temperature environment for a long time, causing its temperature to gradually rise.

[0004] This elevated platen temperature negatively impacts the stable passage of the edge banding. Specifically, as the edge banding passes through the narrow space between the platen and the adhesive pot, the high temperature of the platen causes thermal deformation, which compromises its shape and dimensional stability. This deformation not only compromises the precise fit of the edge banding to the sheet material but can also cause defects such as warping and ripples, ultimately severely impacting the overall edge quality and aesthetics of the sheet material.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0028] like Figure 1-Figure 4As shown, a belt pressing device for an edge banding machine includes a belt pressing main board 4, which is rotatably connected to a base, wherein the base is fixedly connected to the edge banding machine, a guide plate assembly is provided on the belt pressing main board, a pressing plate 7 is installed on the belt pressing main board, a fixed assembly is provided on the base, and a driving member 8 is provided on the belt pressing main board, which can abut against the fixed assembly to drive the pressing plate to swing, thereby approaching or moving away from the molten glue pot, thereby realizing the clamping and gluing of the edge banding.

[0029] In at least one embodiment, the guide plate assembly includes an outer guide plate 52 and an inner guide plate 51. The inner guide plate is fixedly connected to the belt press main plate. Pads 10 are clamped and fixed to the bottom of the outer and inner guide plates to support the edge banding. The design of the guide plate assembly provides stable support, ensuring that the edge banding remains straight during processing, improving the accuracy and aesthetics of the edge banding.

[0030] Furthermore, extension positioning blocks 101 are provided on both sides of the cushion block, and in coordination therewith, the bottoms of the outer guide plate and the inner guide plate are provided with limiting slots 521 that cooperate with the extension positioning blocks.

[0031] In at least one embodiment, a height limiting assembly is installed on the guide plate assembly, and the height limiting assembly includes a height limiting plate 6, a sliding groove 61 is formed in the middle of the height limiting plate, and a fixed block 53 is slidably fitted in the sliding groove. The fixed block is fixedly connected to the top of the outer guide plate by bolts and nuts, and a limiting plate 54 is provided on the side of the fixed block away from the outer guide plate. The limiting plate, the fixed block and the outer guide plate are penetrated by a locking bolt and a handle nut 55. The design of the guide plate assembly and the height limiting assembly can control the direction and height of the edge banding strip, thereby improving the edge banding accuracy and efficiency.

[0032] Furthermore, a handle 62 is provided on the top of the height limiting plate.

[0033] The locking bolt and handle nut enable the height limit plate to be moved relative to the outer guide plate and positioned at a point on the outer guide plate. This design allows the height limit plate to be flexibly adjusted and securely locked, meeting the varying edge banding sizes and processing requirements.

[0034] In at least one embodiment, Figure 1 As shown, the pressing plate is fixedly connected to the pressing belt main board by a pressing plate bolt 73. An air inlet 74 and several air outlets 75 are provided on the pressing plate. Because the pressing plate is close to the melt glue pot and the temperature is relatively high, the blowing design can effectively reduce the temperature of the pressing plate and prevent deformation or damage caused by high temperature.

[0035] Furthermore, the belt press mainboard is threaded with a main adjustment screw 72, which rests against the surface of the pressure plate. Side adjustment screws 71 are threaded into the side walls of the pressure plate, which rest against the side walls of the belt press mainboard. Because the edge banding tape needs to be clamped between the pressure plate and the melt glue pot, the pressure plate must be parallel to the pot's glue axis. Multiple adjustment screws allow for fine-tuning of the pressure plate's angle. To complement this, the belt press mainboard is provided with a waist-shaped hole, through which the pressure plate bolts thread into the threaded holes of the pressure plate.

[0036] The design of adjusting top screw and waist-shaped hole allows the angle of the pressing plate to be fine-tuned, ensuring the parallelism between the pressing plate and the melt glue pot, thereby improving the accuracy and stability of edge sealing.

[0037] In at least one embodiment, the fixing assembly includes a fastening bolt 33, a first spring 32, a rotating seat 31, a top plate 2, a positioning column 1, and a pressure plate shaft 3. The top and bottom of the pressure belt main plate are respectively provided with an upper connecting plate 41 and a lower connecting plate 42. The fastening bolt passes through the upper connecting plate, the pressure plate shaft, the lower connecting plate, and the rotating seat in sequence and is then threadedly connected to the base. The pressure plate shaft is slidably fitted with a top plate. A first spring is provided between the top plate and the upper connecting plate. A horizontal adjustment bolt 21 is threadedly connected to the top plate. The end of the horizontal adjustment bolt rests on the lower connecting plate. A positioning column is installed at one end of the top plate away from the pressure plate shaft, and the positioning column is inserted into the mounting hole of the base. Because the first spring squeezes the top plate, the top plate is constantly stressed, and the stress on both sides of the top plate is uneven. The positioning column on the other side is only inserted into the base. With the horizontal adjustment bolt resting on the lower connecting plate, the two ends of the top plate can be kept horizontal.

[0038] In at least one embodiment, the driving member is an electric cylinder or a pneumatic cylinder, which provides a reliable and fast driving force, making the swinging of the pressure plate more precise and efficient.

[0039] In at least one embodiment, a reset mechanism is installed on the driving member. The addition of the reset mechanism enables the pressure plate to automatically return to the initial position after each operation, thereby improving the degree of automation and operational convenience of the device.

[0040] The reset mechanism includes two pressure plate top shafts 91, which are fixedly connected to the driving member. The other end of the pressure plate top shaft is fixedly connected to an adjustment plate 92, and a screw 93 is threadedly connected to the adjustment plate. An adjusting handwheel 95 is installed at the end of the screw. The screw is also threadedly connected to a locking plate 94, and the locking plate is slidably matched with the two pressure plate top shafts. A second spring 96 is provided between the locking plate and the top plate.

[0041] The locking plate allows the elastic force of the second spring to be adjusted. The handwheel is turned until the end of the screw retracts to the adjustment plate. At this point, the screw and locking plate are no longer threaded together. The screw can be manually moved relative to the top axis of the pressure plate and the handwheel is turned again to force the screw through the threaded hole in the locking plate. This design allows the user to adjust the preload of the second spring as needed, thereby precisely controlling the response speed and force of the reset mechanism.

[0042] By adjusting the depth of the screw into the adjustment plate, the swing angle of the press belt mainboard can be precisely controlled, thereby improving the flexibility and precision of the edge banding machine.

[0043] Furthermore, the second spring forces the top plate to rest against the telescopic rod of the driver. This design ensures that when the driver retracts, the second spring can quickly push the top plate back to its initial position, thereby achieving rapid resetting of the pressure plate.

[0044] Furthermore, the top plate is located between the top shafts of the two pressing plates.

[0045] Furthermore, the end of the screw rod is slidably fitted with a sliding sleeve 97, and the sliding sleeve is located between the second spring and the top plate.

[0046] Working method: fix the base to the edge banding machine. Use the fastening bolts to fix the belt pressing mainboard to the base, and ensure that the positioning column is inserted into the mounting hole of the base. The belt pressing mainboard can rotate around the pressure plate axis, and adjust the horizontal adjustment bolts to keep both ends of the top plate level. According to the requirements of the edge banding, adjust the position of the height limit plate in the height limit assembly and fix it with the locking bolts and handle nuts. Use the main adjustment screw and the side adjustment screw to fine-tune the angle of the pressure plate to ensure that the pressure plate is parallel to the melt glue pot. Check the blowing function to ensure that the air inlet and outlet are unobstructed to cool the pressure plate.

[0047] Start the edge banding machine and put the press device into operation. As needed, the electronically controlled switching of the drive element (such as an electric cylinder or pneumatic cylinder) moves the press plate closer to or farther from the glue pot, clamping and applying glue to the edge banding. The combination of the drive element and the reset mechanism allows the press plate to flexibly switch positions, enabling quick transitions between applying glue and pausing it.

[0048] During use, regularly check the tightness of each component and adjust the position of the top screw to ensure stable operation of the device. Clean the air inlet and outlet to prevent blockage and maintain normal blowing function. If any abnormality or malfunction is found, stop the machine immediately for inspection and repair.
