As a further improvement, the cutting mechanism comprises a cutting knife and a driving mechanism for driving the cutting knife to move up and down, and the PLC is electrically connected with the driving mechanism.
Further, the driving mechanism is an air cylinder or an electric push rod.
Furthermore, a first supporting platform corresponding to the cutting knife is arranged between the upper side and the lower side of the side belt and the middle belt.
Furthermore, a second support table corresponding to the pressing belt is arranged between the upper side and the lower side of the middle belt.
Furthermore, the trimming knife is close to the output end of the side band, and a waste material collecting frame is arranged below the output end of the side band.
Advantageous effects
Compared with the prior art, the utility model has the advantages that:
according to the utility model, two pressing rollers which are horizontally arranged and a pressing belt which connects the two pressing rollers are arranged above the middle belt between the two trimming knives, the side belts and the middle belt are driven by the same driving roller, one of the pressing rollers is connected with a third motor, so that the pressing belt, the side belts and the middle belt move in opposite directions and at the same speed, the pressing belt presses the damping sheet to perform trimming through the two trimming knives, the damping sheet is small in deformation and cannot shift, and the error after trimming is small.

Detailed Description
The utility model will be further described with reference to specific embodiments shown in the drawings.
Referring to fig. 1 and 2, a trimming and blanking device for a damping fin for a vehicle comprises a conveying belt and a PLC controller. The upper portion of the input end of the conveying belt is provided with a cutting mechanism, two sides of the output end of the conveying belt are respectively provided with a trimming knife 1, each trimming knife 1 is respectively connected with a first motor 2, and the first motor 2 drives the trimming knife 1 to rotate to trim the damping sheet. The conveying belt comprises a middle belt 3 and side belts 4 positioned on two sides of the middle belt 3, the length of each side belt 4 is smaller than that of the middle belt 3, a gap is formed between each side belt 4 and the middle belt 3, and the trimming knife 1 is positioned in the gap. A pressing mechanism is arranged above the middle belt 3 between the two trimming knives 1 and comprises two pressing rollers 5 which are horizontally arranged and a pressing belt 6 which connects the two pressing rollers 5, the side belt 4 and the middle belt 3 are driven by the same driving roller 7, one pressing roller 5 is connected with a third motor, the driving roller 7 is connected with a second motor 8, the other end of the side belt 4 is installed on a first driven roller 15, the other end of the middle belt 3 is installed on a second driven roller 16, the driving roller 7, the first driven roller 15 and the second driven roller 16 are installed on a conveying belt bracket 14, so that the moving directions of the pressing belt, the side belt and the middle belt are opposite and the speeds of the pressing belt and the middle belt are consistent, the damping sheet pressed by the pressing belt 6 is trimmed by the two trimming knives 1, the damping sheet is small in deformation and cannot shift, and the error after trimming is small. The PLC controller is electrically connected with the cutting mechanism, the first motor 2, the second motor 8 and the third motor.
The cutting mechanism comprises a cutting knife 9 and a driving mechanism 10 for driving the cutting knife 9 to move up and down, the cutting knife 9 spans the middle belt 3 and the two side belts 4, and the PLC is electrically connected with the driving mechanism 10. Preferably, the driving mechanism 10 is a cylinder or an electric push rod, and has a simple structure and is convenient to install.
