Technical Field

[0001] This utility model discloses a low-temperature freezing last pressing machine, which belongs to the field of shoe machinery. Background Technology

[0002] Low-temperature freezing last press, a last press with freezing function.

[0003] Existing pressing machines require materials to be sent to a freezer for freezing and shaping after use. However, when the materials are taken out and sent to the freezer, they still carry residual heat and are not pressed by the pressing machine. During this process, the materials will rebound, causing the materials to deform as a whole.

[0004] A new solution is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature cryogenic pressing machine to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a low-temperature refrigeration pressing machine includes a machine body, wherein the machine body has a refrigeration chamber for placing a compressor, a cooling chamber for placing an evaporator, and a working chamber for placing materials. One side of the cooling chamber is connected to the working chamber through an air inlet channel, and the other side is also connected to the working chamber through a return air channel. The air inlet channel is provided with a fan for passing air along the evaporator and sending it into the working chamber.

[0007] Preferably, the working chamber also has a fixed plate and a moving plate for receiving materials, the fixed plate and the moving plate can be close to each other, and the surface of the moving plate is provided with heat exchange fins.

[0008] Preferably, the fixed plate is suspended in the air, and heat dissipation fins are formed on the side close to the fuselage.

[0009] Preferably, the working chamber is provided with an air inlet wall and a return air wall, which are arranged alternately and adjacent to each other, dividing the working chamber into working areas.

[0010] Preferably, the machine body is slidably provided with a sliding cover for sealing the work area, the sliding cover being able to slide to seal the work area.

[0011] Preferably, the air inlet wall is connected to the air inlet channel and has an air inlet hole on its surface that is connected to the working area; the return air wall is connected to the return air channel and has a return air hole on its surface that is connected to the working area.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, a low-temperature refrigeration pressing machine includes a machine body 1. Inside the machine body 1, there are a refrigeration chamber 2 for placing a compressor, a cooling chamber 3 for placing an evaporator 8, and a working chamber 4 for placing materials. One side of the cooling chamber 3 is connected to the working chamber 4 through an air inlet channel, and the other side is also connected to the working chamber 4 through a return air channel 9. The air inlet channel is equipped with a fan 7 for passing air along the evaporator 8 and sending it into the working chamber 4.

[0019] This product uses a compressor for refrigeration, then sends the refrigerant from the compressor to the evaporator 8, causing the temperature of the evaporator 8 to drop rapidly. Then, by starting the fan 7, air is drawn through the fins of the evaporator 8, achieving heat exchange and further reducing the air temperature. Driven by the fan 7, the low-temperature air is pumped from the air inlet channel into the working chamber 4. As the low-temperature air is pumped into the working chamber 4, the air pressure inside the working chamber 4 increases, causing the previously hot air in the working chamber 4 to rush into the lower-pressure return air channel 9 and finally flow back to the cooling chamber 3 to be cooled by the evaporator 8. Through this cycle, the temperature inside the working chamber 4 drops rapidly, allowing the pressing machine to simultaneously cool down during the pressing process. This achieves simultaneous pressing and low-temperature setting, eliminating the need for a refrigeration unit for low-temperature setting after pressing.

[0020] The working chamber 4 also has a fixed plate 52 and a moving plate 51 for receiving materials. The fixed plate 52 and the moving plate 51 can approach each other. The surface of the moving plate 51 is provided with heat exchange fins 511. Since the moving plate 51 needs to move within the working chamber 4, it can slide through most of the area of ​​the working chamber 4. The heat exchange fins 511 allow the moving plate 51 to cool down faster when it moves, thereby improving the cooling speed of the material and achieving faster cooling efficiency.

[0021] The fixed plate 52 is suspended in the air, and a heat dissipation fin 521 is formed on the side close to the body 1. In traditional cases, the fixed plate 52 is attached to the body 1, and air can only exchange heat on five sides when it flows. One side is attached to the body 1, preventing air from passing through from below. This product designs the fixed plate 52 to be suspended in the air, so that all six sides of the fixed plate 52 are in contact with the flowing air, thereby achieving better heat exchange. Furthermore, the setting of the heat dissipation fin 521 further improves the efficiency of heat exchange.

[0022] The working chamber 4 is provided with an air inlet wall 61 and a return air wall 62. The air inlet wall 61 and the return air wall 62 are arranged alternately and adjacent to each other, dividing the working chamber 4 into working areas. The air inlet wall 61 is connected to the air inlet channel and has an air inlet hole on its surface that is connected to the working area. The return air wall 62 is connected to the return air channel 9 and has a return air hole on its surface that is connected to the working area. The air inlet wall 61 is used for air outlet and the return air wall 62 is used for air return. When the air flows, it will inevitably pass through the material between the air inlet wall 61 and the return air wall 62, so that the material can better contact the cold air for cooling effect.

[0023] The body 1 is equipped with a sliding cover for sealing the working area. The sliding cover can be slid to seal the working area. The design of the sliding cover can separate the product from the outside world when it is working, thereby reducing the energy loss of cold air exchange with the outside world.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
