[0036] When the food is quick-frozen, first, the food to be frozen can be transported to the import lifting door 8 through the input conveying device 9, wherein, under the detection action of the detector 3, the detection result can be fed back to the system of the quick-freezing control mechanism to assist the entire freezing process, which will not be described in detail here, and then, the reciprocating motion component is started (the detector 3 can control the automatic start of the reciprocating motion component, and can also control the speed of the reciprocating motion component), the reciprocating motion component drives the quick-freezing control component and the reverse positioning opening and closing component to move at the same time, and the directions of the two movements are opposite, that is, the quick-freezing The control component moves toward the direction of the inlet lift door 8, and the reverse positioning opening and closing component moves toward the direction of the outlet lift door 4. At the intersection of the two (i.e., the middle position of the tunnel freezer 1), auxiliary freezing and turning over of the food can be performed to ensure the freezing effect. For details, please refer to the following content. When the two are completely moved to the end position of the tunnel freezer 1, the reverse positioning opening and closing component can also control the opening of the inlet lift door 8, and only when the reverse positioning opening and closing component reaches the outlet lift door 4 (i.e., only when the quick freezing control component reaches the inlet lift door 8), the reverse positioning opening and closing component The inlet lifting door 8 is controlled to open only when the quick-frozen component is in place, so that the food that needs to be quickly frozen can quickly enter the tunnel freezer 1 for freezing, avoiding the inlet lifting door 8 from opening early or late, and the process of discharging the food after quick freezing is similar to this, wherein the equipment for quick freezing of food can adopt the existing technology and be installed on the tunnel freezer 1, and the cold air outlet is directly opposite to each surface on the transport control base 10, and the cold air outlet can be smoothly installed and set by opening holes or slots on each component on the transport control base 10, and the specific installation position is not specifically limited here, and is set according to actual needs, and no further details are given here, and finally the quick-frozen food is discharged to the outside of the equipment through the output conveying device 5, the operation is simple, and the food can be fully frozen (that is, the quick freezing control component has not reached the inlet lifting door 8, and the inlet lifting door 8 will not be opened, which can ensure the food is fully frozen), and the tunnel door is opened after the mobile frame moves to the specified position, which is conducive to improving the effect of freezing the food, and avoiding the tunnel door from opening early or late due to equipment failure, thereby affecting the smooth progress of the freezing work, and providing convenience for the staff.

[0037] In one embodiment of the present invention, see Figure 1-Figure 14 , the reciprocating motion assembly comprises: A forward and reverse motor 18, wherein the forward and reverse motor 18 is fixedly mounted on the transport control base 10; A driving wheel 17, wherein the number of the driving wheels 17 is two, and both of the driving wheels 17 are rotatably mounted on the transport control base 10, wherein one of the driving wheels 17 is fixedly connected to the output end of the forward and reverse motor 18; And a conveyor belt 16, which is wound around the two driving wheels 17 and is respectively connected to the quick-freezing control component and the reverse positioning opening and closing component.

[0038] See also Figure 1-Figure 14 , the quick freezing control component comprises: A supporting slide 11, wherein the supporting slide 11 is fixedly connected to the transport control base 10, and the number of the supporting slide 11 is two; A movable slide plate 12 and a movable slide plate 2 14, wherein the movable slide plate 12 and the movable slide plate 2 14 are respectively slidably mounted on the two supporting slide seats 11, and the movable slide plate 12 and the movable slide plate 2 14 are connected via a driving connecting frame 15, and the driving connecting frame 15 is also fixedly connected to the reciprocating motion assembly; And a mobile freezing frame 13, wherein the mobile freezing frame 13 is located between the mobile slide plate 12 and the mobile slide plate 2 14.

[0039] It also includes: a lifting control device 25, the number of the lifting control devices 25 is two, and the two lifting control devices 25 are connected to the moving slide 1 12 and the moving slide 2 14 respectively; A flip shaft 23, the flip shaft 23 is rotatably mounted on the two lifting control devices 25, and the flip shaft 23 is also rotatably connected to the mobile freezing frame 13; An adjusting gear 24, wherein the adjusting gear 24 is fixedly mounted on one end of the flip shaft 23; And a flip driving member, which is connected to the reverse positioning opening and closing component and is detachably connected to the adjusting gear 24.

[0040] During the quick freezing of food, the forward and reverse motors 18 are started to drive the driving wheel 17 to rotate and the conveyor belt 16 to rotate synchronously. During the movement of the conveyor belt 16, the driving frame 15 is driven to move, and the moving slide plate 1 12 and the moving slide plate 2 14 are driven to move synchronously, so that the mobile freezing frame 13 can be driven to move in the tunnel type freezer 1 for quick freezing operation. Among them, a clamping device is arranged on the mobile freezing frame 13, and the clamping device can adopt the form of matching the existing spring and the clamping plate to fix the food to be frozen on the mobile freezing frame 13, and the mobile freezing frame 13 can accommodate multiple layers of food to ensure the efficiency of the speed operation. When the amount of food on the mobile freezing frame 13 is small and the total amount is light, at this time, the lifting control device 25 is in the initial state and is stationary. In this process, the adjusting gear 24 is always not in contact with the flip driving member, so that the stability of the food in the quick freezing process can be ensured under the condition of sufficient cooling. When the food is large, At this time, freezing is more difficult. In order to ensure the freezing effect, when the total amount exceeds the set value, the lifting control device 25 is started. The lifting control device 25 is in the form of a telescopic plate, which is powered by a telescopic cylinder and can drive the flip shaft 23 and the mobile freezing frame 13 to move downward a short distance. At the intersection of the quick-freezing control component and the reverse positioning opening and closing component, the adjusting gear 24 contacts the flip driving member. The flip driving member can be in the form of a flip toggle gear plate 31, so that the adjusting gear 24 can be pushed to rotate and drive the flip shaft 23 to rotate synchronously. After the adjusting gear 24 is completely separated from the flip toggle gear plate 31, the mobile freezing frame 13 just rotates 180°, so that the food originally at the bottom is transferred to the upper part, avoiding the poor quick-freezing effect of some food in the part in contact with the mobile freezing frame 13. At the same time, after the weight reaches a certain level, the quick-freezing equipment can increase the degree of freezing and reduce the speed of the forward and reverse motor 18. No further details will be given here.

[0041] In one embodiment of the present invention, see Figure 1-Figure 14 , the reverse positioning opening and closing component comprises: An L-shaped support plate 19, wherein the L-shaped support plate 19 is fixedly connected to one of the support slides 11, and a guide groove 20 is formed on the L-shaped support plate 19; An opening and closing control base 21, wherein the opening and closing control base 21 is slidably mounted on the transport control base 10 via a supporting slide 22, and the opening and closing control base 21 is also connected to the reciprocating motion assembly; A telescopic sleeve 27, the telescopic sleeve 27 is fixedly connected to the opening and closing control base 21, and a lifting support plate 28 is inserted on the telescopic sleeve 27, the lifting support plate 28 is slidably connected to the telescopic sleeve 27, and a sliding column 26 is also fixedly installed on the lifting support plate 28; The sliding cylinder 26 is inserted into the guide groove 20 and is slidably connected with the guide groove 20; And a pulling unit, wherein the pulling unit is connected to the tunnel freezer 1, the outlet lifting door 4, the inlet lifting door 8 and the lifting support plate 28 respectively.

[0042] The pulling unit comprises: A lifting bracket 32, wherein the lifting bracket 32 ​​is fixedly connected to the lifting support plate 28, and a plurality of guide rollers 33 are rotatably mounted on the lifting bracket 32; A guide fixed pulley 35, wherein the number of the guide fixed pulley 35 is multiple, and the multiple guide fixed pulleys 35 are evenly distributed and installed in the tunnel type freezer 1, and are rotatably connected to the inner wall of the tunnel type freezer 1; Steel wire ropes 34, the number of the steel wire ropes 34 is two, one end of one of the steel wire ropes 34 is fixedly connected to the outlet lifting door 4, one end of the other steel wire rope 34 is fixedly connected to the inlet lifting door 8, and the other end of the steel wire rope 34 is passed around the plurality of guide fixed pulleys 35; and a lifting and pulling column 36, wherein the lifting and pulling column 36 is slidably connected to the inner wall of the tunnel freezer 1, and the number of the lifting and pulling column 36 is two, and the two lifting and pulling columns 36 are respectively fixedly connected to the ends of the two steel wire ropes 34; Furthermore, the lifting and pulling column 36 is detachably connected to the guide roller 33 .

[0043] See also Figure 1-Figure 12 , further comprising: an auxiliary nozzle 29, wherein the number of the auxiliary nozzles 29 is multiple, and the multiple auxiliary nozzles 29 are evenly distributed on the opening and closing control base 21; And an image detection device 30 , wherein the image detection device 30 is fixedly installed at the middle position of the opening and closing control base 21 .

[0044] During the movement of the conveyor belt 16, the opening and closing control base 21 can be driven to move synchronously, wherein the opening and closing control base 21 is provided with an auxiliary nozzle 29 and an image detection device 30. When the total weight of the food on the mobile freezing frame 13 reaches a set value, the auxiliary nozzle 29 can be made to spray cold air, thereby achieving the purpose of auxiliary freezing. At the same time, the image detection device 30 transmits the detected image to the information display board 2, wherein the information display board 2 also displays the temperature in the tunnel freezer 1 and the speed of the mobile freezing frame 13. Parameters such as the speed, which will not be described in detail here, and during the movement of the opening and closing control base 21, the sliding column 26 will be made to move synchronously in the guide groove 20. Since the guide groove 20 is composed of an inclined groove section 1, a straight groove section and an inclined groove section, The groove section is composed of two parts and is a U-shaped structure. When the opening and closing control base 21 moves to the end, the sliding column 26 performs the inclined groove section, which pushes the lifting support plate 28 to move upward in the telescopic sleeve 27, and drives the flip-toggle tooth plate 31 and the lifting bracket 32 ​​to move upward synchronously. When the guide roller 33 contacts the lifting and pulling column 36, it pushes the lifting and pulling column 36 to move upward. At this time, the lifting and pulling column 36 rolls with the multiple guide rollers 33 on the lifting bracket 32 ​​in turn, which can reduce the effect of friction. When the lifting and pulling column 36 moves upward, it pulls the wire rope 34, and pulls the outlet lifting door 4 or the import lifting door 8 upward to open through the wire rope 34, so as to facilitate the feeding and discharging of food. No more details are given here.

At this time, the guide roller 33 on the lifting support plate 28 contacts the lifting and pulling column 36, and pushes the lifting and pulling column 36 to move upward. When the lifting and pulling column 36 moves upward, it pulls the inlet lifting door 8 upward through the wire rope 34 for feeding food; On the contrary, the moving freezing frame 13 and the opening and closing control base 21 move in opposite directions, which is used for discharging the quick-frozen food.
