The detailed connection means is a technique known in the art, and the following mainly describes the working principle and process, and the specific operation is as follows.
Example (b): as can be seen from the attached figures 1-6 of the specification, firstly, the cooling structure is arranged at the right side of the raw material extruder in the prior art, so that the extruded raw material can be positioned above the left end of the cooling seat; secondly, fixedly connecting the base 11 of the cutting structure 1 with the cooling box 21 of the cooling assembly 2 to form a production line mode, and simultaneously adding a certain amount of clear water into the cooling box 21;
secondly, the equipment is driven by the first electric push rod 25 on the control bracket 24 to contract, so that the sliding frame 31 in the traction structure 3 can be driven to move by the pulley 32; when the sliding frame 31 moves to the left end of the cooling box 21, the hydraulic cylinder 34 in the protective pipe 33 is controlled to stretch and retract to drive the guide frame 371 in the guide assembly 37 to ascend and descend, and the second motor 36 in the drive box 35 is controlled to drive the guide frame 371 to rotate for a certain angle, so that the two conveying rollers 374 are positioned above the cooling box 21 and inclined for a certain angle, and then the second electric push rod 373 is controlled to contract and drive to drive the sliding base 372 to move in the guide frame 371, so that the two conveying rollers 374 are separated, namely, a larger distance is generated through the inclined position;
then, the raw material extruded in the extruder can be inserted between two conveying rollers 374; then, the guide frame 371 is clamped by two conveying rollers 374 and then reset, and the guide frame is inserted into the cooling box 21, and the guide frame 371 is vertically downward; the first electric push rod 25 is used for driving in an extending mode again, the guide frame 371 can penetrate through the first roller frame 22, the conveying rollers 374 can penetrate through the lower portions of the first guide rollers 23 to move, after the belt conveying pipes penetrate through the two first guide rollers 23, the first hydraulic cylinder 34 and the second motor 36 are driven again, the traction end is lifted, the third motor 375 can be controlled to drive, and the conveying rollers 374 at the bottom can be driven to rotate to apply force to convey the cold raw materials through transmission of the second belt 377 sleeved on the second belt wheel 376;
finally, the traction end of the raw material is inserted into the left end of the driving shaft rod 132 of the cutting assembly 13 carried by the support frame 12 for limited conveying; meanwhile, the first motor 17 is controlled to drive, on the same principle, the first belt 19 sleeved on the transmission belt wheel 18 is used for transmission, so that the rotation of the driving shaft rod 132 shielded and protected by the protective cover 16 in one cutting assembly 13 is driven, the secondary transmission is realized due to the mutual meshing of the first gear 14 and the second gear 15 on the two driving shaft rods 132, and the difference of the rotating speeds of the two driving shaft rods 132 is realized due to the different tooth numbers of the diameters;
in the rotation of the driving shaft 132, when the return force groove moves the limiting rod of the cutting knife 133, the cutting knife 133 is stressed to extend out of the conveying hole for cutting, and when the limiting rod of the cutting knife 133 is in the return force groove, the cutting knife 133 is contracted and reset in the telescopic groove; thus, during rotation of the drive shaft 132, a continuous, reciprocating extension cut is made by the two pairs of cutters 133;
further, since the rotation speed of the driving shaft 132 is different, and the rotation conveying speed of the conveying roller 374 is constant, the cutting of the particles with different lengths can be realized.
