[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See Figures 1-6As shown, it includes a frame 1, a "V"-shaped feeding trough 3 is provided at the middle of the rear end of the frame 1, and two clamping shafts 4 are symmetrically arranged up and down at the front end of the feeding trough 3, and an elastic feeding component is provided in the middle of each clamping shaft 4, a clamping shaft 2 8 is provided on the front side of each clamping shaft 4, and a flexible clamping shaft 9 is provided in the middle of each clamping shaft 2 8, and a "V"-shaped feeding trough is opened on the flexible clamping shaft 9, and elastic clamping components are provided on both sides of the two clamping shafts 4 respectively, and the two clamping shafts 4 are rotatably connected to the elastic clamping components, and elastic clamping components are also provided on both sides of the two clamping shafts 2 8 in the same way, and the clamping shafts 4 and the elastic clamping assembly of the clamping shaft 2 8 are symmetrically arranged; a cutter mounting bracket 16 is vertically provided at the front side of the flexible clamping shaft 9 in the frame 1, and an outlet hole 17 is opened in the cutter mounting bracket 16. A horizontal knife 18 and a vertical knife 19 are respectively provided on the inner side of the cutter mounting bracket 16. The angle between the horizontal knife 18 and the vertical knife 19 is 90°, and the horizontal knife 18 and the vertical knife 19 are staggered front and back. An array of oblique knives 21 is also provided on the outside of the outlet hole 17. A conveyor belt 2 is provided at the front end of the outlet hole 17 on the frame 1, a power assembly is provided in the frame 1, and a detection sensor 27 for detecting the position of the lettuce is provided at the lateral position between the clamping shaft 1 4 and the clamping shaft 2 8 in the frame 1;

[0027] A bevel knife telescopic cylinder 20 is provided on the cutter mounting frame 16, and each bevel knife 21 is connected to the top of the movable rod 11 of the bevel knife telescopic cylinder 20. There are four bevel knife telescopic cylinders 20, and the angle between each bevel knife telescopic cylinder 20 and the horizontal knife 18 and the vertical knife 19 is 45°. In the front-to-back direction, the bevel knife 21 is located between the horizontal knife 18 and the vertical knife 19.

[0028] By combining the horizontal knife 18 and the vertical knife 19 into a cross shape, the fed lettuce can be evenly cut into four strips, and since the horizontal knife 18 and the vertical knife 19 are staggered front and back, the horizontal and vertical cutting can be separated. The lettuce first contacts the horizontal knife 18 and is cut into two strips, and then contacts the vertical knife 19 to be divided into four strips. The oblique knife telescopic cylinder 20 is extended before the lettuce enters, so that the oblique knife 21 forms a rice shape with the horizontal knife 18 and the vertical knife 19. On the basis of the four lettuce strips, the four lettuce strips are separated from the middle. The detection sensor 27 continuously detects the position of the lettuce. When the signal disappears, it indicates that the tail end of the lettuce has left the detection range. The oblique knife 21 can be retracted after a certain delay, so that the four lettuce strips form a herringbone shape with the front end separated and the tail end connected, which is convenient for subsequent hanging and drying. The delay length is comprehensively determined by the feeding speed and the length that needs to be retained at the tail of the lettuce strip.

[0029] See Figure 1-Figure 4As shown, a discharging telescopic cylinder 22 is provided at the top of the front end of the frame 1 facing downward, and the top of the discharging telescopic cylinder 22 is connected to a "door"-shaped driving frame 23. The driving frame 23 is located directly above the conveyor belt 2, and a flexible pressure roller 24 is rotatably installed at the bottom end of the driving frame 23.

[0030] The discharging telescopic cylinder 22 drives the driving frame 23 to rise and fall, thereby making the flexible pressing roller 24 press the sent lettuce strips, increasing the friction between the conveyor belt 2 and the lettuce, so that the lettuce strips can be pulled out through the conveyor belt 2 and transported forward.

[0031] See Figure 1-Figure 7 As shown, the elastic clamping assembly includes a fixed rod 10 installed on the side beam of the frame 1, and the upper and lower ends of the fixed rod 10 are respectively connected to the movable rod 11, one end of the movable rod 11 is rotatably connected to the fixed rod 10, and the other end of the movable rod 11 is installed with a bearing 12, and the two ends of the clamping shaft 2 8 are respectively connected to the bearing 12, and the inner side of each movable rod 11 is connected to a spring connecting rod 13, and a spring connecting rod 2 14 opposite to the spring connecting rod 13 is provided on the beam on which the fixed rod 10 is installed, and a clamping spring 15 is connected between the spring connecting rod 13 and the spring connecting rod 2 14.

[0032] The upper and lower clamping shafts 1 and 4 are pulled toward the middle by the spring connecting rod 2 14 , thereby driving the two elastic feeding components to clamp the lettuce, and the flexible clamping shaft 9 guides and feeds the lettuce forward while clamping it.

[0033] See Figure 1-Figure 4 As shown, the elastic feeding assembly includes two circular fixed plates 5 symmetrically arranged on the clamping shaft 4, and a number of flexible clamping strips 6 are arranged between the two fixed plates 5. The two ends of each flexible clamping strip 6 are connected to the fixed plate 5 through a spring 7, and the number of flexible clamping strips 6 are evenly distributed around the center of the fixed plate 5.

[0034] The flexible clamping strip 6 is tightened by the spring 7, so that the lettuce is compressed by the flexible clamping strip 6. The combined design of the spring 7 and the flexible clamping strip 6 reduces the local pressure on the surface of the lettuce to prevent damage to the lettuce.

[0035] See Figure 1-Figure 4 As shown, the power assembly includes a main motor 25 arranged in the frame 1, and the rotating shaft of the main motor 25 is connected to the clamping rotating shaft 1 4, the clamping rotating shaft 2 8 and the conveyor belt 2 through a sprocket set 26.

[0036] The main motor 25 is used to synchronously drive multiple components of the device through the sprocket set 26.
