DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-4 A veneer coating machine for door frames in the present application comprises a base plate 1, partition plates 6 are arranged on the front and rear sides above the base plate 1, two coating rollers 7 placed at the same level are rotatably arranged between the two partition plates 6, a plurality of electric push rods 8 located on the left sides of the two coating rollers 7 are fixedly connected to the top of the base plate 1, a pad plate 9 is fixedly connected to the top of the plurality of electric push rods 8, two support plates 10 are fixedly connected to the top of the pad plate 9, a self-locking mechanism 11 fixedly connected to the partition plate 6 is arranged on one side of the two support plates 10 close to the partition plate 6, and a tensioning roller 12 is rotatably arranged above the two support plates 10.

[0019] In the above embodiment, the veneer first passes through the tensioning roller 12 and the coating roller 7, and then the electric push rod 8 is started to adjust up and down to make the veneer tighter when winding. The partition 6 limits the coating roller 7, and the two coating rollers 7 are at the same level and fit the coating roller 7 more closely. The veneer moves from the top of the tensioning roller 12 to the bottom of the left coating roller 7 to the top of the right coating roller 7. Then, after adjusting to the corresponding position, the self-locking mechanism 11 starts to work, limiting the electric push rod 8 so that the electric push rod 8 will not slowly drop due to time, thereby effectively improving work efficiency and reducing cost losses.

[0020] Furthermore, the self-locking mechanism includes a rack fixedly connected to one side of the support plate 10 close to the partition 6, a shell 1101 fixedly connected to one side of the two partitions 6 close to the rack, a magnet 1102 is provided on the inside of the two shells 1101 close to the partition 6, two limit rods 1103 are provided in parallel up and down inside the shell 1101, a slide plate 1104 is slidably sleeved on the two limit rods 1103, a spring 1105 fixed to the slide plate 1104 is sleeved on the limit rod 1103, an electromagnet 1106 is provided on one side of the slide plate 1104 close to the magnet 1102 and is in the same horizontal plane as the magnet 1102, and a limit block 1107 engaged with the rack is fixedly connected to the other side of the slide plate 1104.
