Description

Technical Field

[0001] The invention relates to the technical field of lobster processing, and in particular to a quick-freezing machine feeding device, a lobster quick-freezing machine and a lobster quick-freezing method. Background Art

[0002] With the development of the crayfish industry, the transportation of crayfish has become an important link, and the correct storage method can maintain the delicious taste and nutritional value of crayfish, while also ensuring the safety and hygiene of food. Before transportation, lobsters need to be frozen in quick-freezing equipment to ensure the taste of the shrimp and facilitate storage and transportation.

[0003] After searching, the announcement number CN221505356U discloses a lobster quick-freezing device, including a body and a uniform component, a conveyor belt is arranged on the body, a quick-freezing bin is installed on the conveyor belt, and the uniform component is installed at the feeding end of the quick-freezing bin to reduce the stacking of lobster freezing and make it evenly frozen. When the lobster quick-freezing device is feeding the lobster, the push cylinder drives the slide to move inside the support frame, so that the slide can drive the shrimp-leveling plate to achieve flexible position adjustment of up and down movement, so that the bottom of the shrimp-leveling plate and the surface of the conveyor belt form a feed port with a limited height, thereby avoiding the problem that the uneven freezing of the lobster affects the processing efficiency. At the same time, because the height limit size of the shrimp-leveling plate can be flexibly matched with the height of the lobster to be processed, the effect is more convenient and the uniform effect is better. A brush is also arranged on one side of the shrimp-leveling plate to facilitate cleaning the surface of the conveyor belt and brushing off the ice layer, thereby improving the convenience and effect of use.

[0004] However, the above-mentioned lobster quick-freezing equipment still has the following problems: the above-mentioned lobster quick-freezing equipment forms a feed port with a restricted height between the bottom of the shrimp plate and the surface of the conveyor belt, so that lobsters can be conveyed through the feed port, and the conveyor belt is brushed by the rolling bristles. Since the lobsters contact each other when passing through the feed port, some moisture remains on the surface of the lobsters due to cleaning and their own water discharge, and thus the lobsters are prone to adhesion after quick freezing. In addition, after the conveyor belt surface is brushed by the bristles, the moisture in the bristles themselves is difficult to remove, and the dewatering effect is poor. Summary of the invention

[0005] The invention provides a quick-freezing machine feeding device, a lobster quick-freezing machine and a lobster quick-freezing method, which solve the problems in the prior art that lobsters are easily adhered to each other after quick freezing and the dewatering effect is poor.

[0006] The technical solution of the present invention is as follows: A feeding device for a quick-freezing machine comprises a conveyor belt and an outer frame arranged on the conveyor belt, a discharge plate is hingedly connected to one side of the outer frame close to the feed port, a material leveling plate is hingedly connected to one side of the outer frame close to the discharge port, a movable frame and a movable frame driving the movable frame to reciprocate along the conveying direction are arranged inside the outer frame, the discharge plate and the material leveling plate rise and fall alternately under the push of the movable frame, two pneumatic mechanisms are arranged inside the movable frame, a linkage mechanism driving the two pneumatic mechanisms to intermittently inject air is arranged at the bottom of the movable frame, drying mechanisms respectively communicated with the two pneumatic mechanisms are arranged on both sides of the movable frame, and the two drying mechanisms cross-swing when the movable frame reciprocates.

[0007] The bottom of the material discharge plate is provided with a bent portion bent toward the lower side of the outer frame, and the bottom of the material leveling plate is fixed with a plurality of equally spaced material dividing rods.

[0008] The movable frame includes a slide rail and a rail beam vertically fixed to the slide rail, the rail beam is arranged along the conveying direction of the conveyor belt, a slide seat slidably connected to the outer frame is fixed on the top of the rail beam, a limiting groove is provided at the bottom of the slide rail, a first waist-shaped groove is provided on the top of the slide rail, a second waist-shaped groove is provided at one end of the rail beam close to the feed port, and bar teeth are provided on both sides of the rail beam.

[0009] The driving mechanism comprises a motor, which is fixed in an outer frame. A horizontally arranged rotating arm is fixed at the bottom end of the output shaft of the motor, and a driving shaft limitedly located in the first waist-shaped groove is fixed at one end of the rotating arm away from the output shaft of the motor.

[0010] The linkage mechanism includes a first swing rod and a second swing rod, the first swing rod and the second swing rod are hinged by a positioning shaft, the positioning shaft passes through the second waist-shaped groove and is fixed to the outer frame, and the first swing rod and the second swing rod are hinged with a hinge shaft at one end away from the positioning shaft.

[0011] The pneumatic mechanism includes a slider, which is slidably arranged in a limit groove and hinged to a hinge shaft. An elastic bag is fixed to one side of the slider, and the end of the elastic bag away from the slider is fixed to the rail beam. An air inlet head is arranged at the bottom of the end of the elastic bag away from the slider, and a heater is fixed to the side of the slider facing away from the elastic bag.

[0012] The heater comprises a tube body and an outer shell fixed outside the tube body, a spirally arranged heating wire is fixed between the tube body and the outer shell interlayer, and an airway is arranged in the slider to connect the tube body with the inner cavity of the elastic bag.

[0013] The drying mechanism includes a rotating shaft, which is rotatably connected to the outer frame. A gear meshing with the bar teeth is fixed on the rotating shaft. An air duct horizontally suspended above the conveyor belt is fixed to the bottom end of the rotating shaft. Equally spaced nozzles are arranged at the bottom of the air duct. A joint is arranged on one side of the air duct, and the joint is connected to the air outlet end of the heater through a hose.

[0014] Based on the above-mentioned quick-freezing machine feeding device, the present invention also proposes a lobster quick-freezing machine, wherein a quick-freezing bin is arranged on the conveyor belt, and the quick-freezing bin is located behind the outer frame in the conveying direction of the conveyor belt.

[0015] Based on the above-mentioned lobster quick-freezing machine, the present invention also proposes a lobster quick-freezing method, comprising the following steps:

[0016] Step 1: The lobsters to be cleaned are transported to the quick freezing chamber via a conveyor belt;

[0021] 1. In the present invention, when the outer frame falls on the conveyor belt, the curved portion of the material discharge plate is approximately in contact with the surface of the conveyor belt. When the lobsters are conveyed by the conveyor belt and pass through the outer frame, they can be blocked by the curved portion of the material discharge plate and be successively flattened along the conveying direction. At this time, the material leveling plate is in a raised state. When the material leveling plate falls on the conveyor belt, the material dividing rod of the material leveling plate is approximately in contact with the surface of the conveyor belt. When the lobsters are conveyed by the conveyor belt and are about to be sent out of the outer frame, they can be combed by the material dividing rod of the material leveling plate, so that a certain distance can be maintained between the lobsters, thereby solving the problem of easy adhesion between lobsters after quick freezing in the prior art;

[0022] 2. In the present invention, when the lobster is released and enters under the outer frame, the pneumatic mechanism continuously injects air into the two drying mechanisms under the action of the linkage mechanism, and at the same time, the two drying mechanisms of the movable frame can cross and swing during the movement, thereby drying the lobster passing below to prevent the surface of the lobster and the conveyor belt from freezing when passing through the quick-freezing chamber, thereby solving the problem of poor water removal effect in the prior art.

[0036] See also Figure 1 and Figure 2 The bottom of the discharge plate 4 is provided with a curved portion 41 bent downwardly from the outer frame 2, and a plurality of equally spaced dividing rods 51 are fixed to the bottom of the leveling plate 5. When the outer frame 2 falls on the conveyor belt 1, the curved portion 41 of the discharge plate 4 is approximately in contact with the surface of the conveyor belt 1. When the lobsters are transported by the conveyor belt 1 and pass through the outer frame 2, they can be blocked by the curved portion 41 of the discharge plate 4 and be flattened successively along the conveying direction. At this time, the leveling plate 5 is in a lifted state. When the leveling plate 5 falls on the conveyor belt 1, the dividing rods 51 of the leveling plate 5 are approximately in contact with the surface of the conveyor belt 1. When the lobsters are transported by the conveyor belt 1 and are about to be sent out of the outer frame 2, they can be combed by the dividing rods 51 of the leveling plate 5, so that a certain distance can be maintained between the lobsters to prevent adhesion during the quick freezing process.

[0037] See also Figure 2 , Figure 3 and Figure 4 The movable frame 6 includes a slide rail 61 and a rail beam 62 vertically fixed to the slide rail 61, the rail beam 62 is arranged along the conveying direction of the conveyor belt 1, a slide seat 63 slidably connected to the outer frame 2 is fixed on the top of the rail beam 62, a limiting groove 64 is provided at the bottom of the slide rail 61, a first waist-shaped groove 65 is provided at the top of the slide rail 61, a second waist-shaped groove 66 is provided at one end of the rail beam 62 close to the feed port, and bar teeth 67 are provided on both sides of the rail beam 62.

[0038] See also Figure 3 and Figure 5 The driving mechanism 7 includes a motor 71, which is fixed in the outer frame 2. A horizontally arranged rotating arm 72 is fixed to the bottom end of the output shaft of the motor 71. The end of the rotating arm 72 away from the output shaft of the motor 71 is fixed with a driving shaft 73 limitedly positioned in the first waist-shaped groove 65. When the motor 71 is working, it can drive the rotating arm 72 to rotate. The driving shaft 73 at one end of the rotating arm 72 is limited in the first waist-shaped groove 65, so that the rail beam 62 can reciprocate in the conveying direction of the conveyor belt 1, and then the rail beam 62 can reciprocate to push the discharge plate 4 and the material leveling plate 5.

[0039] See also Figure 3 and Figure 6 The linkage mechanism 8 includes a first swing arm 81 and a second swing arm 82. The first swing arm 81 and the second swing arm 82 are hinged by a positioning shaft 83. The positioning shaft 83 passes through the second waist-shaped groove 66 and is fixed to the outer frame 2. The first swing arm 81 and the second swing arm 82 are hinged with a hinge shaft 84 at one end away from the positioning shaft 83. During the reciprocating motion of the rail beam 62 in the conveying direction of the conveyor belt 1, since the positioning shaft 83 is fixed on the outer frame 2, the first swing arm 81 and the second swing arm 82 can swing crosswise.

[0040] See also Figure 3 and Figure 7 The pneumatic mechanism 9 includes a slider 91, which is slidably arranged in the limit groove 64 and hinged with the hinge shaft 84. An elastic bag 92 is fixed on one side of the slider 91. The end of the elastic bag 92 away from the slider 91 is fixed on the rail beam 62. An air inlet head 93 is arranged at the bottom of the end of the elastic bag 92 away from the slider 91. A heater 94 is fixed on the side of the slider 91 facing away from the elastic bag 92. It should be noted that a one-way valve is arranged in the air inlet head 93, which can only allow external air to enter the elastic bag 92 through the air inlet head 93. The first swing arm 81 and the second swing arm 82 can swing crosswise, and then the sliding limit of the slider 91 by the limit groove 64 can make the slider 91 reciprocate and compress the elastic bag 92. Due to the presence of the one-way valve in the air inlet head 93, the air in the elastic bag 92 can be squeezed out to the heater 94 through the air channel in the slider 91.

[0041] See also Figure 7 and Figure 8The heater 94 includes a tube body 941 and an outer shell 942 fixed to the outside of the tube body 941. A spirally arranged heating wire 943 is fixed between the tube body 941 and the outer shell 942. An air passage connecting the tube body 941 with the inner cavity of the elastic bag 92 is arranged in the slider 91. It should be noted that a one-way valve is arranged in the air passage of the slider 91. The one-way valve can only allow the air in the elastic bag 92 to enter the heater 94. When the air squeezed out by the elastic bag 92 passes through the tube body 941, it is heated by the heating wire 943 between the tube body 941 and the outer shell 942, and is guided to the drying mechanism 10 through the transportation of the hose.

[0042] See also Figure 3 and Fig. 9 The drying mechanism 10 includes a rotating shaft 101, which is rotatably connected to the outer frame 2. A gear 102 meshing with the bar teeth 67 is fixed on the rotating shaft 101. An air duct 103 horizontally suspended above the conveyor belt 1 is fixed at the bottom of the rotating shaft 101. Nozzles 104 distributed equidistantly are arranged at the bottom of the air duct 103. A joint 105 is arranged on one side of the air duct 103. The joint 105 is connected to the air outlet end of the heater 94 through a hose. During the reciprocating movement of the rail beam 62 in the conveying direction of the conveyor belt 1, the meshing of the bar teeth 67 on both sides of the rail beam 62 and the gear 102 can drive the air duct 103 to reciprocate around the rotating shaft 101 as the rotation point, and then the nozzles 104 on the bottom of the air duct 103 cross-blow hot air to the lobsters passing by.

[0043] Based on the above embodiments, the present invention further proposes a lobster quick-freezing machine, wherein a quick-freezing bin 3 is provided on the conveyor belt 1 , and the quick-freezing bin 3 is located behind the outer frame 2 in the conveying direction of the conveyor belt 1 .

[0044] Based on the above embodiments, the present invention also proposes a lobster quick freezing method, comprising the following steps:

[0045] Step 1: The lobsters to be cleaned are transported to the quick freezing chamber 3 via the conveyor belt 1;

[0046] Step 2: When passing through the outer frame 2, the material can be blocked by the falling discharge plate 4 and leveled successively along the conveying direction, and at this time, the leveling plate 5 is in a raised state;

[0047] Step 3: The moving frame 6 moves in the opposite direction of the conveying direction under the driving mechanism 7, so that the discharge plate 4 is lifted to release the leveled lobsters and enter the bottom of the outer frame 2, and the leveling plate 5 gradually changes from the lifted state to the dropped state and sorts the lobsters passing by, so that the lobsters are kept at a certain distance;

[0048] Step 4: The combed lobsters enter the quick-freezing bin 3 and are sent out after being quick-frozen in the quick-freezing bin 3.

[0049] When the lobster is released and enters under the outer frame 2 in step three, the pneumatic mechanism 9 continuously injects air into the two drying mechanisms 10 under the action of the linkage mechanism 8, and at the same time, the two drying mechanisms 10 can cross-swing during the movement of the movable frame 6, thereby drying the lobster passing below to prevent the surface of the lobster and the conveyor belt 1 from freezing when passing through the quick-freezing chamber 3.

[0050] In the present invention, the process when the lobster enters the lower part of the outer frame 2 is as follows: the motor 71 drives the rotating arm 72 to rotate, and the driving shaft 73 at one end of the rotating arm 72 is limited in the first waist-shaped groove 65, so that the rail beam 62 reciprocates in the conveying direction of the conveyor belt 1. In this process, since the positioning shaft 83 is fixed on the outer frame 2, the first swing arm 81 and the second swing arm 82 can swing crosswise, and then the sliding limit of the slider 91 by the limiting groove 64 can make the slider 91 reciprocate and compress the elastic bag 92. Due to the presence of the one-way valve in the air inlet head 93, the air in the elastic bag 92 can pass through the air in the slider 91. The lobsters are extruded to the heater 94 and are heated by the heating wire 943 between the tube body 941 and the outer shell 942 when passing through the tube body 941. The lobsters are guided to the drying mechanism 10 through the conveying of the hose. When the rail beam 62 reciprocates in the conveying direction of the conveyor belt 1, the meshing of the bar teeth 67 on both sides of the rail beam 62 and the gear 102 can drive the air duct 103 to reciprocate around the rotating shaft 101 as the rotation point, and then the nozzle 104 on the bottom of the air duct 103 cross-blows hot air to the lobsters passing by, so that the moisture on the surface of the lobsters and the conveyor belt 1 evaporates, so as to prevent the surface of the lobsters and the conveyor belt 1 from freezing when passing through the quick-freezing chamber 3.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
