[0003] The tunnel-type quick freezer includes a conveyor belt and a refrigeration section located above the conveyor belt. The conveyor belt includes an inlet end and an outlet end. People first place food on the inlet end of the conveyor belt. The food passes through the refrigeration section under the action of the conveyor belt and then reaches the outlet end of the conveyor belt. In the process of passing through the refrigeration section, the food will be frozen, thereby achieving the effect of preservation. For the convenience of operation, existing staff will place a collection box below the outlet end of the conveyor belt. The food will fall directly into the collection box under the action of the conveyor belt. People will wait until the collection box is full and then lift the collection box away. The frozen food can be directly packaged and transported. However, the opening of the collection box is always connected to the outside. Some foods are large in size and move slowly on the conveyor belt, which makes the interval time for the food to fall into the collection box longer, resulting in more cold air escaping from the collection box.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a food quick-freezer.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a food quick freezer, including a frame and a conveyor belt arranged on the frame, an insulation plate for shielding the opening of a collection frame is arranged on the lower side of the frame, a through groove running through the thickness direction of the insulation plate is opened, shielding strips are fixedly connected to the two side walls of the through groove, and several of the shielding strips are elastic. The shielding strips are used to shield the through groove, and a rubber pad for contacting the collection frame is arranged on the lower side of the insulation plate.

[0007] The utility model is further configured as follows: a sliding groove is provided on the lower side of the frame and is provided along the length direction of the conveyor belt; a sliding block is slidably connected in the sliding groove; and the sliding block is used for driving the heat preservation plate to slide out from under the frame.

[0008] The utility model is further configured as follows: a circular groove is opened on the side of the sliding block facing the insulation board, a sliding rod is slidably connected in the circular groove, one end of the sliding rod facing away from the circular groove is fixedly connected to the insulation board, and an elastic member is provided above the insulation board, and the elastic member provides downward movement force for the insulation board.

[0009] The utility model is further configured as follows: the elastic member is a compression spring sleeved on the sliding rod, one end of the compression spring abuts against the sliding block, and the other end of the compression spring abuts against the heat preservation plate.

[0010] The utility model is further configured as follows: the frame is fixedly connected with two limit frames respectively located on both sides of the conveyor belt, and a limit cavity for sliding the insulation board is formed between the two limit frames and the frame.

[0011] The utility model is further configured as follows: the through groove includes a guide groove and a rectangular groove which are interconnected, the guide groove is arranged close to the upper side of the insulation board, the area of ​​the guide groove becomes larger the farther away from the rectangular groove, and a plurality of the shielding strips are fixed on the inner wall of the rectangular groove.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Food quick freezer, such as Figure 1 and Figure 4 As shown, it includes a frame 1, a conveyor belt 2 arranged on the frame 1 and a refrigeration part located above the conveyor belt 2. A heat preservation plate 3 for shielding the opening of the collection frame is arranged on the lower side of the frame 1. A through groove 4 running through the thickness direction is opened on the heat preservation plate 3. Shielding strips 5 are fixedly connected to the two side walls of the through groove 4. The through groove 4 is used for food to pass through. The shielding strips 5 are elastic. The shielding strips 5 are used to shield the through groove 4. The shielding strips 5 always remain in a horizontal state without the action of external force. A rubber pad 6 for contacting with the top surface of the collection frame is arranged on the lower side of the heat preservation plate 3. When people place the collection frame under one end of the conveyor belt 2, people make the rubber pad 6 on the lower side of the heat preservation plate 3 contact with the upper side of the collection frame, so that the cold air is not easy to The food flows out from the gap between the insulation plate 3 and the collection frame, and falls into the collection frame through the groove 4. Since the food has an impact force on the shielding strip 5, the movable end of the shielding strip 5 is deformed. After the food passes through the groove 4, the shielding strip 5 returns to a horizontal state under the action of its elasticity, so that all the shielding strips 5 jointly block the groove 4. The shielding strips 5 can limit the cold air in the collection frame from escaping through the groove 4, thereby greatly reducing the amount of cold air escaping. This arrangement greatly reduces the amount of cold air escaping during the interval time of the food falling, thereby ensuring the overall freezing degree of the food, and then ensuring the time of food transportation. The insulation plate 3 also has a certain insulation effect at the same time, which reduces the amount of temperature change in the collection frame.

[0021] like Figure 2 and Figure 3As shown, a sliding groove 7 is provided on the lower side of the frame 1 along the length direction of the conveyor belt 2, and a slider 8 is slidably connected in the sliding groove 7. The slider 8 is used to drive the insulation board 3 to slide out from the bottom of the frame 1. Limiting grooves are provided on both sides of the sliding groove 7, and limiting strips are provided on both sides of the slider 8 located in the limiting grooves. The limiting strips are used to limit the slider 8 from escaping from the sliding groove 7. When the slider 8 is located at the end of the sliding groove 7 facing the refrigeration part, the end of the insulation board 3 facing away from the refrigeration part is flush with one end of the conveyor belt 2. This arrangement makes it possible for people to move the insulation board 3 to the bottom of the frame 1 by sliding the slider 8 when the quick-freezing machine is not in use, so that the insulation board 3 does not affect the aisle next to the quick-freezing machine, and the position of the through-groove 4 can be adjusted by sliding the slider 8, so that the through-groove 4 can smoothly allow food to pass through. A circular groove 9 is provided on the side of the slider 8 facing the insulation board 3, and the circular groove 9 is vertically arranged. The sliding rod 17 slides along the depth direction of the circular groove 9, and the end of the sliding rod 17 facing away from the circular groove 9 is fixed to the insulation board 3 by bolts. An elastic member is provided above the insulation board 3, and the elastic member provides a force for the insulation board 3 to move downward. By sliding the sliding rod 17 in the circular groove 9, the insulation board 3 can be controlled to move up and down, so that the insulation board 3 can adapt to collection frames of different heights, and the setting of the elastic member makes the rubber pad 6 and the collection frame fit more tightly, further ensuring the sealing between the insulation board 3 and the collection frame. The elastic member is a compression spring 10 sleeved on the sliding rod 17, one end of the compression spring 10 is in contact with the slider 8, and the other end of the compression spring 10 is in contact with the insulation board 3. The compression spring 10 has the characteristics of easy installation, which is convenient for people to install, and the compression spring 10 is in contact with the slider 8, so that the setting of the elastic member has little effect on the sliding of the slider 8.

[0022] like Figure 4As shown, there are two limit frames 11 fixedly connected to the frame 1, which are respectively located on both sides of the conveyor belt 2. A limit cavity 12 for sliding into the insulation board 3 is formed between the two limit frames 11 and the frame 1. The length of the limit frame 11 is less than 1 / 3 of the length of the insulation board 3. When the insulation board 3 is located in the limit cavity 12, the compression spring 10 is in a compressed state. This arrangement allows people to slide the insulation board 3 into the limit cavity 12 when the quick freezer is not in operation. This arrangement allows the insulation board 3 to maintain a higher position, so that there is more space under the frame 1. The through groove 4 includes a guide groove 13 and a rectangular groove 14 that are interconnected. The guide groove 13 is arranged close to the upper side of the insulation board 3. The farther the area of ​​the guide groove 13 is from the rectangular groove 14, the larger it is. A plurality of shielding strips 5 are fixed in the rectangular groove On the inner wall 14, the guide groove 13 can increase the area of ​​the food falling into the through groove 4, so that when people slide the slider 8, the position of the through groove 4 is easier to adjust, reducing the difficulty of people's operation. The insulation board 3 includes a structural layer 15 and an insulation layer 16. The guide groove 13 is opened on the structural layer 15, and the rectangular groove 14 is opened on the insulation layer 16. The structural layer 15 is made of stainless steel, and the insulation layer 16 is made of polyester ammonia foam. Stainless steel has the characteristics of high strength and impact resistance, which ensures the overall strength of the structural layer 15, so that the food is not easily damaged by the impact force of falling. The polyester ammonia foam has a good insulation effect, which ensures the insulation effect of the insulation board 3. At the same time, the sliding rod 17 is also fixed on the structural layer 15, which is convenient for people to fix the sliding rod 17 with bolts.
