The dispensing tube is fixed to the moving part of the second linear motor. The dispensing tube is connected to the dispensing tube of an external glue supply device. The external glue supply device provides glue to the dispensing tube. A support plate 10 is installed on the top of the support frame 4 through a connecting assembly. The connecting assembly includes multiple fixing blocks 2. The multiple fixing blocks 2 are fixed to the top of the support frame 4 by bolts. A guide rod 5 is fixed between corresponding two fixing blocks 2 by bolts. A slider 6 is fixed to the top of the support plate 10 by bolts. The slider 6 is slidably connected to the two guide rods 5. The guide rods 5 can guide the slider 6 to prevent the slider 6 from tilting during movement.

[0019] In particular, the support plate 10 and the support frame 4 are fixed together by a pin assembly. The pin assembly includes a first fixing plate 8, which is fixed to one end of the slider 6 by bolts. The first fixing plate 8 has a slot, and a rod 7 is inserted into the slot. Two holes 3 are opened on both sides of the top of the support frame 4, and the rod 7 is inserted into the corresponding hole 3. The support plate 10 is slid laterally along the guide rod 5 on the support frame 4 via the slider 6, and manually adjusted to the required position below the dispensing assembly 1, so that the rod 7 is in the corresponding position of the hole 3. Then the rod 7 is inserted into the slot of the first fixing plate 8 and passes through the hole 3 of the support frame 4 to fix the support plate 10 and the support frame 4. The top of the rod 7 extends out of the slot and is fixed with a magnet 9 by bolts. The magnet 9 is attracted to the first fixing plate 8, and the magnet 9 at the top of the rod 7 is magnetically attached to the first fixing plate 8 to prevent the rod 7 from easily loosening.

[0020] It should be noted that the support plate 10 has multiple limiting grooves 13, which are arranged in a straight line on multiple sides of the support plate 10.

The baffle 11 further restricts the position of the cardboard. Then the card holder 19 is released and the spring 17 rebounds to make the card holder 19 lock the corresponding position of the card slot 18, so that the limiting block 12 is locked. Then the glue dispensing position of the glue dispensing assembly 1 is adjusted so that the glue dispensing assembly 1 dispenses glue to the surface of the cardboard.

[0021] Working principle: When it is necessary to apply glue to a square cardboard, the support plate 10 is slid laterally along the guide rod 5 on the support frame 4 via the slider 6, and manually adjusted to the required position below the glue application assembly 1, so that the insertion rod 7 corresponds to the insertion hole 3. Then, the insertion rod 7 is inserted into the slot of the first fixing plate 8 and passes through the insertion hole 3 of the support frame 4, thereby fixing the support plate 10 to the support frame 4. The magnetic block 9 at the top of the insertion rod 7 is magnetically attached to the first fixing plate 8 to prevent the insertion rod 7 from easily loosening. The operator pulls the card holder 19 to make it move along the positioning... As column 16 moves, spring 17 contracts, and the positions of multiple limiting blocks 12 are adjusted according to the size of the square cardboard. Specifically, according to the size of the cardboard, the corresponding position of the limiting block 12 is selected in the limiting groove 13 on multiple sides of the support plate 10 and inserted, so that the limiting block 12 contacts multiple sides of the cardboard. The baffle 11 further restricts the position of the cardboard. Then, the card holder 19 is released, and spring 17 rebounds, causing the card holder 19 to lock into the corresponding slot 18, thus locking the limiting block 12. Then, the dispensing position of the dispensing assembly 1 is adjusted so that the dispensing assembly 1 dispenses glue onto the surface of the cardboard.
