DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a liquid nitrogen tunnel quick freezer that is easy to load, comprising two groups of side panels 1, a conveying motor 3 is fixedly installed at one end of the side panel 1, multiple groups of conveying rollers 2 are equidistantly rotatably installed between the two groups of side panels 1, and a conveyor belt 4 is provided on the surface of the multiple groups of conveying rollers 2 located between the two groups of side panels 1, the conveying rollers 2 at one end of the two groups of side panels 1 close to the conveying motor 3 pass through the side panels 1 and are fixedly connected to the conveying motor 3, by providing a conveyor belt 4, starting the conveying motor 3 to control the conveying roller 2 to rotate, so that the conveying roller 2 and the conveyor belt 4 rub against each other, and controlling the conveying belt 4 to convey and move, and the quick-frozen items are moved through the bottom of the quick-freezing machine body 5 for quick freezing.

[0023] The quick-freezing machine body 5 is fixedly installed on the top of the two groups of side panels 1, and two groups of fixing plates 6 are symmetrically fixedly installed on the side panels 1 located on one side of the quick-freezing machine body 5. A positioning column 601 is fixedly installed on the top of the fixing plate 6, and a T-shaped clamping block 602 is fixedly installed on the bottom of one side of the fixing plate 6, and the T-shaped clamping block 602 corresponds to the T-shaped slot 702. Because the T-shaped clamping block 602 and the T-shaped slot 702 are provided, after the T-shaped slot 702 is clamped on the surface of the T-shaped clamping block 602, it is ensured that the mounting seat 7 will not be misaligned when it is clamped between the two groups of fixing plates 6;

[0024] The side panel 1 is located between the two groups of fixed plates 6 and is fixedly installed with a mounting base 7. Two groups of positioning screw holes 701 are provided at the central position of one side of the mounting base 7. T-shaped slots 702 are symmetrically provided at the bottom of both sides of the mounting base 7. Fixed rods 703 are slidably installed on both sides of the mounting base 7 at the top of the T-shaped slots 702; a fixed socket 603 is provided on one side of the fixed plate 6 at the top of the T-shaped block 602, and the fixed socket 603 corresponds to the fixed rod 703. Since the fixed socket 603 and the fixed rod 703 are provided, after the fixed rod 703 is inserted into the fixed socket 603, the mounting base 7 is clamped and fixed between the two groups of fixed plates 6.

[0025] One end of the fixed plug rod 703 passes through the mounting seat 7, and a limiting plate 704 is fixedly installed on the surface of the fixed plug rod 703 located inside the mounting seat 7, and a fixing spring 705 is provided on the surface of the fixed plug rod 703 located on one side of the limiting plate 704, and a lever 706 is fixedly installed on one end of the fixed plug rod 703 located inside the mounting seat 7, and the lever 706 passes through the surface of the mounting seat 7 and a fixing clamping plate 8 is provided, and by providing a fixing spring 705, the limiting plate 704 is pushed toward the two sides of the mounting seat 7 under the rebound action of the fixing spring 705, so that the fixed plug rod 703 can be pushed out of the mounting seat 7 and snapped into the corresponding fixed socket 603;

[0026] Concave slots 801 are symmetrically provided on both sides of the fixed card plate 8, and the concave slots 801 correspond to the lever 706. A positioning bolt 802 is provided at the central position of the fixed card plate 8 between the two groups of concave slots 801, and the positioning bolt 802 passes through the fixed card plate 8 and is connected with the positioning screw hole 701. Because the fixed card plate 8 is provided, the fixed card plate 8 is pushed to make the concave slots 801 slide on the surface of the lever 706. After the lever 706 is located at both ends of the concave slots 801, the positioning bolts 802 are tightened to clamp and fix the lever 706 to ensure that the lever 706 will not cause the fixed plug rod 703 to slide at will.

[0027] A guide mechanism 9 is fixedly installed on the top of the two sets of mounting seats 7. The guide mechanism 9 includes two sets of mounting plates 901, and positioning holes 902 are provided at both ends of the bottom of the mounting plates 901, and the positioning holes 902 correspond to the positioning columns 601. The two sides between the two sets of mounting plates 901 are fixedly installed with limited sliding rods 903. Due to the limited sliding rods 903, the moving seat 905 slides on the surface of the limited sliding rods 903, ensuring that the moving seat 905 will not tilt or deflect during the movement;

[0028] A bidirectional screw 904 is rotatably installed at the central position between the two groups of mounting plates 901, and moving seats 905 are symmetrically provided on the surfaces of the bidirectional screw 904 and the two groups of limiting slide bars 903 on both sides, and a guide plate 906 is fixedly installed on the bottom of the moving seat 905. By providing the bidirectional screw 904, the bidirectional screw 904 is controlled to rotate, so that the two groups of moving seats 905 on the surface of the bidirectional screw 904 are moved closer to or farther away from each other on the surface of the limiting slide bar 903, thereby adjusting the distance between the two groups of guide plates 906.

[0029] Both ends of the bidirectional screw 904 pass through the mounting plate 901 and are fixedly installed with locking studs 907, one end of the locking stud 907 is fixedly installed with a screw block 908, and a locking screw sleeve 909 is provided on the surface of the locking stud 907. Because the locking screw sleeve 909 is provided, the locking screw sleeve 909 is tightened to fit the mounting plate 901 to lock and fix the locking stud 907, thereby clamping and fixing the bidirectional screw 904.

[0030] The working principle of the utility model is:

[0031] After the fixing bolts 702 are loosened and the fixing card plate 8 is lifted up, the two sets of levers 706 are pushed and squeezed to be close to each other in the corresponding concave slots 801. After the fixing plug rods 703 are retracted into the mounting seat 7, the two sets of mounting seats 7 are respectively clamped between the two opposite fixing plates 6, so that the T-shaped slots 702 are clamped on the surfaces of the corresponding T-shaped blocks 602. At the same time, the positioning posts 601 are inserted into the positioning holes 902. The fixing card plate 8 is pushed to make the fixing plug rods 703 drive the levers 706 to move to both sides of the fixing card plate 8 under the rebound action of the fixing springs 705, until the fixing plug rods 703 are inserted into the fixing plug holes 603, and the fixing card plate 8 is pushed down. The sliding fixed clamping plate 8 clamps and fixes the lever 706, loosens the locking screw sleeve 909, controls the screw block 908 to drive the bidirectional screw 904 to rotate, and controls the movable seat 905 to drive the guide plate 906 to move according to the size of the quick-frozen object, until the distance between the two sets of guide plates 906 corresponds to the size of the quick-frozen object, tightens the locking screw sleeve 909 to lock and fix the bidirectional screw 904, starts the conveying motor 3 to place the quick-frozen object on the top of the conveyor belt 4, and after being guided by the guide plate 906, the quick-frozen object can be quick-frozen at the central position at the bottom of the quick-freezing machine body 5.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
