[0006] The utility model is further configured as follows: the tension positioning frame comprises a base and two slidably matched tension blocks located on the base, a spring is arranged between the two tension blocks, and the spring drives part of the tension block to slide outside the base.

[0007] The utility model is further configured as follows: the top of the support frame extends to the top wall of the freezing box body for rotational cooperation, and the bottom thereof is located on a rotating platform, and the two ends of the spiral rod are respectively inserted into the support frame and rotationally cooperate with the support frame.

[0009] By adopting the above technical solution, the shoes to be cooled and shaped can be fixed on the tension positioning frame, so that the soles of the shoes can be cooled by cold air. The tension positioning frame can swing left and right through the trend of the driving part, so that the shoes can be cooled more evenly. At the same time, the whole swinging assembly is rotated by the driving of the rotating table, which further improves the uniformity of the cooling of the shoes and improves the cold shaping quality of the shoes.

DETAILED DESCRIPTION

[0014] Reference Figures 1 to 3 The embodiments of the utility model are further described.

[0015] A cold setting device for producing shoes, comprising a freezing box and a refrigerator 2, wherein an air duct 20 of the refrigerator 2 extends into the freezing box, wherein a positioning and swinging device is arranged in the freezing box, comprising a rotating table 4 and a swinging assembly 3 linked to the rotating table 4, wherein the swinging assembly 3 comprises a support frame 30, two tension positioning frames 31 and a driving part 32 for driving the tension positioning frames 31 to swing, wherein the driving part 32 comprises a spiral rod 320, a gear ring 321 meshing with the spiral rod 320, and a push rod 322 hinged to one side of the gear ring 321, wherein a "7"-shaped swing arm 313 is arranged on the tension positioning frame 31, wherein the "7"-shaped bending part of the swing arm 313 is assembled on the support frame 30 by a rotating pin, wherein the tail ends of the two swing arms 313 are connected to a swing shaft 314, and the push rod 322 extends to the middle position of one of the swing arms 313 and is hinged. The tension positioning frame 31 includes a base 310 and two slidably matched tension blocks 311 on the base 310, and a spring 312 is provided between the two tension blocks 311, and the spring 312 drives a portion of the tension block 311 to slide out of the base 310. The top of the support frame 30 extends to the top wall of the freezing box for rotational cooperation, and its bottom is located on the rotating platform 4. The two ends of the spiral rod 320 are respectively inserted into the support frame 30 and rotate with the support frame 30.

[0016] The freezing box body 1 includes a main box body 10 and a sub-box body 11, a hollow layer 12 is formed between the main box body 10 and the sub-box body 11, the air guide pipe 20 on the refrigerator 2 extends into the hollow layer 12, and the sub-box body 11 is provided with a plurality of air guide ports 13 connected to the hollow layer 12.

[0017] Working principle: The shoe opening is placed on the tension positioning frame 31, and the distance between the two tension blocks 311 is automatically adjusted through the cooperation of the two tension blocks 311, which is convenient for fixing shoes of different calibers. After the door of the freezing box 1 is closed, the refrigerator 2 transports the cold air to the hollow layer 12, and the cold air in the hollow layer 12 enters the auxiliary box 11 through the air guide port 13 to freeze the shoes in the freezing box 1, which is conducive to improving the uniformity of the cold air in the entire freezing box 1. The entire swing assembly 3 is driven by the rotation of the rotating table 4 to rotate in the circumferential direction, which can better improve the uniformity of the cooling of the shoes. At the same time, the spiral rod 320 is controlled by the motor to rotate forward, the gear ring 321 rotates clockwise, the push rod 322 moves toward the right tension positioning frame 31, and the push rod 322 pushes the swing arm 313 to swing. At this time, the tension positioning frame 31 on the right is in a state of being lifted up, and the tension positioning frame 31 on the left is linked with the swing shaft 314 to make the swing arm 313 on the left tilted, driving the tension positioning frame 31 on the left to swing downward. When the spiral rod 320 rotates in the opposite direction, the gear ring 321 rotates counterclockwise, driving the tension positioning frame 31 on the left to be lifted upward, and the tension positioning frame 31 on the right to be swung downward. This is repeated, which can further improve the more uniform cooling of the shoes (refer to the attached illustration). Figure 1 and 2 status).

[0018] The height position of the tension positioning frame 31 corresponds to the position of the air duct 20 on the cooler 2. The position of the air outlet 13 at this height is the working position with the most cold air. The tension positioning frame 31 is set to a swinging structure, which can continuously change the working position of the shoes, accelerate the cooling effect, and make the shoes cool more evenly.

[0019] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
