[0047] The coating machine 100 of the application can adjust the distance between the two feeding side beams 21 and the two discharging side beams 41 according to the size of the processed product by slidingly arranging the feeding side beams 21 and the discharging side beams 41 on the rack 10, and has better versatility. Compared with the traditional coating machine 100 with a replaceable moving frame, the coating machine 100 of the application does not need to be equipped with multiple moving frames, has lower equipment cost, and has higher efficiency in switching different sizes of products, thereby improving the utilization rate of the equipment. Moreover, by opening the first air avoiding groove 11 for accommodating the front distance adjusting power component 22 and the second air avoiding groove 12 for accommodating the rear distance adjusting power component 42 on the rack 10, the overall structure of the equipment can be more compact.
[0048] As Figure 3As shown, a first slider is provided at the bottom of the feed side beam 21, and a first guide rail corresponding to the first slider is provided on the frame 10. Similarly, a second slider is provided at the bottom of the discharge side beam 41, and a second guide rail corresponding to the second slider is provided on the frame 10.
[0049] In this embodiment, both the front pitch adjustment power component 22 and the rear pitch adjustment power component 42 are servo motors, and their transmission structures are identical. The specific structure of the front pitch adjustment power component 22 will be described below.

Both ends of the film pressing roller 53 are equipped with lifting slide plates that are slidably connected to the film feeding bracket 51. The lifting slide plates are connected to the lead screw. By turning the handwheel, the height of the film pressing roller 53 can be adjusted so that the height of the film pressing roller 53 matches the thickness of the product.
[0055] Furthermore, the discharge drive 43 is positioned close to the pressure roller 53, and the frame 10 is provided with a third clearance groove 13 corresponding to the discharge drive 43. By opening the third clearance groove 13 on the frame 10, the discharge drive 43 can be housed in the third clearance groove 13, avoiding interference between the discharge drive 43 and the pressure roller 53, and also making the equipment structure more compact.
[0056] In this embodiment, both the feeding drive 23 and the discharging drive 43 are motors.

The feeding rollers 241 on the front middle beam 24 can reduce the resistance during product conveying and at the same time avoid damage to the surface quality of the product. Setting the front pitch adjustment power unit 22 at the bottom of the front middle beam 24 can make the whole machine more compact; similarly, by setting the rear middle beam 44, the product can be subjected to uniform force when conveying the product, ensuring the coating quality. The discharge roller 441 can reduce the resistance of product conveying and protect the surface quality of the product. Setting the rear pitch adjustment power unit 42 at the bottom of the rear middle beam 44 can make the whole machine more compact.
