[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a new type of gantry pelletizer head of the utility model includes a material guide seat installed in front of the extrusion mechanism, and the material guide seat is composed of a front discharge seat 2 and a rear feed seat 1. The front discharge seat 2 is arranged in front of the rear feed seat 1, and a cutting channel 15 is formed between the front discharge seat and the rear feed seat 1. A cutting blade 5 is provided above the cutting channel 15, and a gantry 4 is provided outside the cutting channel 15. A driving mechanism for driving the cutting blade 5 to move back and forth up and down is installed on one side of the gantry 4.

[0021] In this embodiment, the front discharge seat 2 and the rear feed seat 1 are both composed of an upper plate and a lower plate, and a plurality of arc grooves are provided on the opposite surfaces of the upper plate and the lower plate, and the upper and lower arc grooves are combined to form a material guide channel 3, and the material guide channel 3 on the front discharge seat 2 is arranged opposite to the guide channel on the rear feed seat 1, and a cross plate 9 is installed at the lower end of the gantry 4, and U-shaped frames 13 are installed at both ends of the cross plate 9, and both ends of the U-shaped frame 13 are bent to form a fixing part 14, and the fixing part 14 is provided with a fixing hole, and the upper plate and the lower plate are provided with screw holes at the positions opposite to the fixing holes, and the vertically opposite screw holes and the fixing holes are threadedly connected with bolts for locking and fixing the upper plate and the lower plate.

[0022] In this embodiment, the driving mechanism includes a cylinder 12 and a plurality of positioning plates 6, and the positioning plates 6 are installed at both ends of the cutting blade 5. A strip opening 7 is vertically provided on one side of the gantry 4, and the positioning plate 6 on one side protrudes opposite the strip opening 7 to form a positioning portion. The positioning portion passes through the strip opening 7 and bends toward one side to form a connecting portion. The piston rod of the cylinder 12 is installed on the bottom surface of the connecting portion, and the outer shell of the cylinder 12 is installed on the outer surface of the gantry 4.

[0023] In this embodiment, positioning grooves 8 are vertically provided on both side surfaces of the gantry 4, and positioning blocks 16 are installed on the outer side surfaces of the positioning plates 6 opposite to the positioning grooves 8. The positioning blocks 16 are slidably set in the positioning grooves 8, so that the cutting blade can only move up and down along the positioning grooves, avoiding deviation, and after the cylinder is detached from the connecting part, the cutting blade can be taken out upward along the positioning grooves and the strip mouth, which is convenient for its replacement.

[0024] In this embodiment, both the top and bottom surfaces of the cutting blade 5 are sharpened, so that both the top and bottom surfaces of the cutting blade can perform cutting operations.

[0025] In this embodiment, the U-shaped frame 13 forms an avoidance groove opposite to the cutting channel 15, so that the cutting blade can move downward smoothly and avoid contact or collision with the U-shaped frame.

[0026] When in use, first unscrew the bolts under the front discharge seat to remove the front discharge seat from the U-shaped frame, so that the front discharge seat can be replaced to change the length of the front discharge seat and the length of the internal guide channel, so that the cut particles can be discharged along the guide channel inside the front discharge seat for a long distance, increase the adaptability of discharge, and can discharge at different distances. After rotation, the front discharge seat can be fixed to the U-shaped frame again by bolts. After the bolts are removed from the front discharge seat and the rear feed seat, the front discharge seat and the rear feed seat can be opened, so that the internal guide channel can be opened, which is convenient for cleaning;

[0027] Among them, after the extruded strip material enters the rear feed seat, the cylinder can be started to make the piston rod of the cylinder reciprocate and extend, and the movement of the piston rod drives the cutting blade, so that the cutting blade can move up and down along the cutting channel, and because the cutting blade is set with upper and lower edges, the cutting blade can perform two cuts when it descends and rises, which increases the cutting efficiency. The cut particles can be squeezed by the particles at the rear and enter the guide channel for the front discharge, and move along the guide channel.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
