[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] See also Figure 1 , a speed measuring device for a corrugated cardboard production line, comprising a beam 1 across a conveyor belt, two ends of the beam 1 being connected to two ends of the conveyor belt through upright posts 2, a box 3 being arranged on the beam 1, a laser speed measuring sensor 4 being arranged in the box 3, the laser speed measuring sensor 4 being connected to a relay box through a cable communication, and the relay box being connected to a controller through an encoder cable communication;

[0014] The cross beam 1 is provided with an anti-deviation structure, which includes a sliding sleeve 5 slidably sleeved on the left and right sides of the cross beam 1, and a first electric push rod 6 is provided on the sliding sleeve 5, and the first electric push rod 6 is installed on the lower wall of the cross beam 1, and a second electric push rod 7 is provided on the lower wall of the sliding sleeve 5, and a baffle 8 is connected to the second electric push rod 7;

[0015] The baffle plate 8 can be used to limit the position of the corrugated cardboard to prevent it from shifting during transportation. The first electric push rod 6 can be used to adjust the horizontal position of the baffle plate 8, so that it can be used according to corrugated cardboards of different sizes. The second electric push rod 7 can be used to adjust the vertical position of the baffle plate 8, so that it can be used for corrugated cardboards of different thicknesses.

[0016] A plurality of rollers 9 are arranged on the surfaces of the baffles 8 close to each other to reduce the friction between the corrugated cardboard and the baffles 8, so as to facilitate the passage of the corrugated cardboard;

[0017] The second electric push rod 7 and the baffle plate 8 are connected via a reinforcing rod 10 to strengthen the connection between the second electric push rod 7 and the baffle plate 8;

[0018] The lower wall of the box body 3 is embedded with optical glass 11 .

[0019] Embodiment: The corrugated cardboard produced by the corrugated cardboard production line is transported to the bottom of the laser speed sensor 4 through the conveyor belt of the cross-cutting machine body. It does not need to contact the corrugated cardboard, avoiding the influence of the traditional speed measuring wheel on the corrugated cardboard. The corrugated cardboard can be limited by the baffle 8 to avoid displacement during transportation. The horizontal position of the baffle 8 can be adjusted by the first electric push rod 6, which is convenient for using corrugated cardboards of different sizes. The vertical position of the baffle 8 can be adjusted by the second electric push rod 7, which is convenient for using corrugated cardboards of different thicknesses. The laser speed sensor 4 converts the signal into a differential signal and sends it to the relay box. The signal waveform given by the laser speed sensor 4 is monitored by RS232. The relay box then processes the signal and transmits it to the controller through the encoder cable. The controller will cut the cardboard according to the set length according to the signal transmitted by the relay box, thereby ensuring the quality of the cross-cutting machine products of the corrugated cardboard production line and reducing the occurrence of waste.
