Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to a heating device for a full-automatic edge banding machine. Background Technique

[0002] An edge banding machine is a highly automated machine that replaces manual edge banding procedures: conveying - applying glue and sticking the edge - cutting - trimming the front and back - trimming the upper and lower edges - fine - trimming the upper and lower edges - scraping the upper and lower edges - polishing. It is mainly divided into semi - automatic and portable types, and is suitable for straight - line edge banding and trimming of medium - density fiberboard, blockboard, solid wood board, particleboard, high - molecular door panel, plywood, etc. It can have functions such as double - sided glue application, edge band cutting, edge band bonding and pressing, trimming, chamfering, rough trimming, fine trimming, scraping, and polishing at one time. The edge banding is delicate, smooth, and has a good feel, and the edge line is straight and smooth. However, the heating device generally used in conjunction with an edge banding machine is inconvenient to adjust the form and size of the discharged glue when melting the hot melt adhesive, and it is difficult to adapt to the simultaneous use of glue sticks and edge - banding granular glue.

[0003] To solve the above - mentioned technical problems, a Chinese patent with the publication number CN216173820U in the prior art discloses a heating device for a full - automatic edge banding machine, including a heating box. Above the heating box, there are a granular feed port and a glue stick feed port. Below the glue stick feed port, there is a first heating coil. Inside the heating box, there is an inserted and connected blanking cylinder. Above the blanking cylinder, there is a fixed ring fixedly connected. Below the heating box, there is a ring - shaped fixed frame fixedly connected. On one side inside the ring - shaped fixed frame, there is a second motor fixedly connected.

[0004] Although the above - mentioned prior - art solution is convenient to adjust the form and size of the discharged glue and can allow the simultaneous use of glue sticks and edge - banding granular glue, its first heating coil and second heating coil are directly arranged in the heating box and the blanking groove. If a malfunction occurs in the two, it is difficult for the staff to quickly take them out of the device for maintenance operations, thus affecting the efficiency of the staff's inspection and maintenance.

One end of the pull rod 12 extending to the inside of the extension groove is rotatably connected to a buckle ring. First, hold the buckle ring and drive the pull rod 12 to move along the inside of the dragging groove, so that the two abutting blocks 9 move away from the protruding ends on both sides of the pressing block 8. After the pressing block 8 is no longer tightly pressed, lift the positioning cover 5 and cooperate with the connecting block to lift the second heating cover 3 together, and the two heating coils 6 are also lifted out for convenient maintenance.

[0029] The implementation principle of the heating device of the fully automatic edge banding machine in the embodiment of the present application is as follows: Hold the buckle ring and drive the pull rod 12 to move along the inside of the dragging groove, so that the two abutting blocks 9 move away from the protruding ends on both sides of the pressing block 8. After the pressing block 8 is no longer tightly pressed, lift the positioning cover 5 and lift the second heating cover 3 together with the connecting block. The two heating coils 6 are also lifted out accordingly for convenient maintenance. After the maintenance is completed, the second heating cover 3 and the positioning cover 5 can be respectively lapped on the first heating cover 2 and the feeding cover 7. Push the pressing block 8 into the pressing groove. The pressing block 8 cooperates with the inclined surface 11 to squeeze the two abutting blocks 9, forcing the two first springs 10 to retract. After the pressing block 8 completely enters the inside of the pressing groove, the abutting blocks 9 pop out and hold both ends of the pressing block 8 to complete the locking and fixing. When disassembling and assembling the heating coil 6, it is necessary to first cooperate with the limiting block 21 and the limiting groove to drive the mounting cover 20 away from the feeding cover 7. The magnetic block 22 and the iron block no longer adsorb, and the spiral conveying blade 17 also moves away from the inside of the feeding cover 7. At this time, the disassembly and assembly operations can be carried out. Starting the first motor 16 can drive the small sprocket and the large sprocket 15 to rotate synchronously through the chain, causing the movable cylinder 13 to move accordingly, and then achieving the effect of rotating the feeding cover 7. During rotation, the connecting block can drive the movable sleeve 4 to deflect without interfering with the rotation process. Starting the second motor can drive the first threaded rod 18 to rotate, and cooperating with the adjustment plate 19 and the adjustment groove can drive the second heating cover 3 to move in the horizontal direction.
