[0042] By means of the above structure; the installation motor 47 is started, and the output shaft of the installation motor 47 rotates to drive the installation shaft 48 to rotate, and the installation shaft 48 rotates to drive the upper active bevel gear 49 to rotate, and the upper active bevel gear 49 drives the rotating shaft 51 to rotate through the upper driven bevel gear 50, and the rotating shaft 51 drives the vertical sprocket 18 to rotate, and the vertical sprocket 18 drives another rotating shaft 51 to rotate through the vertical chain 17, and at the same time, the vertical chain 17 rotates to drive the extrusion column 43 to move, and the extrusion column 43 moves to squeeze the inner wall of the extrusion hole 44, thereby moving the U-shaped fixing rod 9, and the movement of the U-shaped fixing rod 9 drives the two mounting plates 8 and the two unloading blocks 7 to move, so that the net chain 4 on the two fixed rails 16 can be directly connected.

[0043] The guide mechanism includes two rectangular columns 35 fixedly installed at the bottom of the cold storage 15, and multiple guide components are installed on the two rectangular columns 35.

[0044] By means of the above structure: the U-shaped fixing rod 9 moves to drive the vertical rod 45 and the two extrusion cylinders 46 to move. When the two extrusion cylinders 46 contact the inclined parts of the two isosceles trapezoidal blocks 41 respectively located in the two rows, the two extrusion cylinders 46 respectively squeeze the two isosceles trapezoidal blocks 41 so that the two isosceles trapezoidal blocks 41 move.

[0048] like Figure 6As shown, the distance between the two vertical inner walls of the extrusion hole 44 is greater than the width of the vertical chain 17, and the extrusion column 43 is located in the middle of the extrusion hole 44. The advantage of this arrangement is that during the rotation of the vertical chain 17, the extrusion column 43 is always located in the extrusion hole 44, so that the circumference of the extrusion hole 44 can be squeezed. The sliding sleeve 33 is located in the middle of the movable plate 31, and the length of the U-shaped sliding rod 32 is greater than the width of the mesh chain 4. The advantage of this arrangement is that the sliding sleeve 33 can move forward and backward, and the two inclined portions of the isosceles trapezoidal block 41 are arranged downward and upward. The advantage of this arrangement is that it is convenient to squeeze the inclined portion of the isosceles trapezoidal block 41 when the extrusion cylinder 46 moves upward or downward.

[0049] The working principle and use process of the present invention are as follows: when in use, the mesh chain 4 can be rolled by starting two driving motors 6 and two rotating motors 1, and the mesh chain 4 spirally rolls upward on a fixed track 16 to feed materials, and spirally rolls downward on another fixed track 16 to discharge materials, and then two kinds of food are placed on the mesh chain 4 for transmission. When two kinds of food with different cooling times need to be frozen at the same time, the two kinds of food are separated from the middle of the mesh chain 4 and placed in sequence;

[0050] At this time, the installation motor 47 can be started, and the output shaft of the installation motor 47 rotates to drive the installation shaft 48 to rotate, and the installation shaft 48 rotates to drive the upper active bevel gear 49 to rotate, and the upper active bevel gear 49 drives the rotating shaft 51 to rotate through the upper driven bevel gear 50, and the rotating shaft 51 drives the vertical sprocket 18 to rotate, and the vertical sprocket 18 drives another rotating shaft 51 to rotate through the vertical chain 17, and at the same time, the vertical chain 17 rotates to drive the extrusion column 43 to move, and the extrusion column 43 moves to squeeze the inner wall of the extrusion hole 44, so that the U-shaped fixing rod 9 moves, and the movement of the U-shaped fixing rod 9 drives the two mounting plates 8 and the two blanking blocks 7 to move, so that the net chain 4 on the two fixed rails 16 can be directly connected;

[0051] At the same time, the U-shaped fixing rod 9 moves to drive the vertical rod 45 and the two extrusion cylinders 46 to move. When the two extrusion cylinders 46 contact the inclined parts of the two isosceles trapezoidal blocks 41 respectively located in the two rows, the two extrusion cylinders 46 respectively squeeze the two isosceles trapezoidal blocks 41 so that the two isosceles trapezoidal blocks 41 move. The movement of the two isosceles trapezoidal blocks 41 respectively drives the two racks 40 to move. The movement of the two racks 40 respectively drives the two positioning blocks 52 to move. The four spring telescopic rods 42 stretch and deform. At the same time, the movement of the two racks 40 respectively drives the two rotating gears 39 to rotate. The rotation of the two rotating gears 39 respectively drives the two round rods 37 and the two The cam 38 rotates, and the extrusion ends of the two cams 38 respectively squeeze the two pressure plates 34 to move them downward. The movement of the two pressure plates 34 causes the two sliding sleeves 33 and the two U-shaped sliding rods 32 to move downward, thereby causing the two moving plates 31 and the two guide rails 12 to move downward. The two return springs 54 are deformed. When the two extrusion cylinders 46 separate from the inclined portions of the two isosceles trapezoidal blocks 41 and respectively contact the vertical side portions of the two isosceles trapezoidal blocks 41, the two guide rails 12 respectively contact the net chains 4 on the two fixed rails 16 at this time. The heights of the two guide rails 12 after contacting the net chains 4 on the two fixed rails 16 are different.

[0052] During the food conveying process, one of the guide rails 12 and the baffle plate 11 can guide the food on the spiral upward mesh chain 4, so that it can fall onto the multiple rotating rollers 21 through the upper inclined slot 55. At the same time, the fixed motor 14 is started to rotate the rotating shaft 13 and the long gear 10. The long gear 10 rotates to drive the short gear 27, the vertical column 22 and the lower driven bevel gear 26 to rotate. The lower driven bevel gear 26 rotates to drive the lower active bevel gear 25 and the horizontal column 23 to rotate. The horizontal column 23 drives the transverse sprocket wheel 57 to rotate. The transverse sprocket wheel 57 drives the other transverse sprocket wheels 57 to rotate through the transverse chain 20. Therefore, the food falling on the rotating roller 21 can be conveyed to the lower inclined slot 56, so that it falls from the lower inclined slot 56 and falls onto the spiral downward mesh chain 4, thereby reducing the conveying distance and the freezing time. In addition, the two extrusion cylinders 46 can be made to contact the vertical side portions of two different isosceles trapezoidal blocks 41 in the two columns as needed, so as to adjust the conveying distance and freeze two kinds of food with different freezing times.

[0053] After the adjustment, if it is necessary to adjust the delivery amount of the two foods, the forward and reverse threaded rods 30 can be rotated by starting the servo motor 29. The rotation of the forward and reverse threaded rods 30 causes the two movable columns 28 to move away from or closer to each other, thereby causing the two rows of movable plates 31 to move away from or closer to each other, thereby causing the two rows of guide rails 12 to move away from or closer to each other, thereby adjusting the position of the guide rails 12 on the mesh chain 4. When placing two kinds of food, they can be placed separately from different positions of the mesh chain 4.

Any person skilled in the art may use the above disclosed technical contents to change or modify them into equivalent embodiments with equivalent changes.
