Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment, and particularly to a refrigeration device for processing sea bass. Background Technology

[0002] In the sea bass processing flow, refrigeration equipment is crucial for ensuring the freshness of intermediate and finished products and delaying spoilage, directly impacting the final product quality. However, current refrigeration equipment suffers from significant shortcomings in practical use. Uneven internal temperature distribution is observed; areas near the air outlet are directly exposed to cold air, resulting in lower temperatures, while corners and deeper shelves are less effectively covered by cold air, leading to higher temperatures. Furthermore, the internal airflow design restricts cold air circulation, creating localized temperature dead zones and preventing certain areas of fish products from maintaining a suitable refrigeration environment. More importantly, fish products are typically stored on trays, and the pressed surfaces in contact with the trays suffer from insufficient contact area with cold air and obstructed heat dissipation, hindering uniform freezing. This affects the quality stability of these fish products and can slow down overall processing efficiency. These issues make existing refrigeration equipment inadequate for meeting actual processing needs. Summary of the Invention

[0003] The main objective of this invention is to provide a refrigeration device for processing sea bass, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A refrigeration device for processing sea bass includes a refrigeration unit. Slide rails are fixedly installed at all four corners of the refrigeration chamber. Slide bars are slidably installed on the inner sides of four sets of slide rails. A switching assembly is installed between the four sets of slide bars. Five flipping components are installed inside the switching assembly. The switching assembly includes a movable frame fixedly installed between the four sets of slide bars. Five sets of fixing plates are fixedly installed inside the movable frame. A transmission rod is rotatably installed between each of the five sets of fixing plates. Gears are fixedly installed on the front and rear sides of each of the five sets of transmission rods. Five sets of... Each of the five sets of round rods has a No. 1 dual-axis synchronous pulley on one side. Each of the five sets of round rods has two sets of pallet frames movably mounted on it. Each of the two sets of pallet frames has two sets of cylinders fixedly mounted on opposite ends. Each of the two sets of pallet frames has two sets of racks fixedly mounted on opposite ends. Four sets of No. 1 synchronous belts are fitted between the five sets of No. 1 dual-axis synchronous pulleys. A No. 1 motor is fixedly mounted on the lower side of the movable frame near the No. 1 synchronous belt. A No. 2 dual-axis synchronous pulley is fixedly mounted on the rotating shaft of the No. 1 motor. A No. 2 synchronous belt is fitted between the No. 2 dual-axis synchronous pulley and the lowest set of No. 1 dual-axis synchronous pulleys.

[0006] Preferably, the flipping assembly includes two sets of lower fish trays disposed inside the tray frame. An upper fish tray is mirror-image disposed on the inner side of the tray frame near the upper side of the upper fish tray. Fixing blocks are fixedly disposed on the front and rear sides of both the lower and upper fish trays. A round shaft is fixedly disposed on each fixing block. A round rod is movably disposed between the lower and upper fish trays near their four corners. Limit blocks are fixedly disposed at the upper and lower ends of each round rod. A spring is sleeved on the outer side of the round rod near the lower and upper fish trays. Two sets of sliding sleeves are disposed on the inner walls of both the front and rear sides of the tray frame. The inner side is provided with movable openings near the upper and lower sides. A rotating shaft is fixedly installed on the inner side of the sliding sleeve. Circular grooves are provided on the inner walls of the front and rear sides of the pallet frame corresponding to the sliding sleeve positions. Guide grooves are provided on the upper and lower sides of the circular grooves. Three dual-axis synchronous pulleys are fixedly installed on the outer sides of the two sets of rotating shafts in the pallet frame. A three-axis synchronous belt is fitted between the two sets of three dual-axis synchronous pulleys. U-shaped seats are fixedly installed on opposite ends of the two sets of pallet frames. A second motor is fixedly installed on the U-shaped seats. Four sets of four-axis synchronous belts are fitted between the three dual-axis synchronous pulleys on the five sets of flipping components.

[0007] Preferably, the movable frame is provided with a handle, the five sets of fixing plates and transmission rods are arranged vertically and evenly, each set of the five sets of fixing plates contains two plates, and the two sets of gears are arranged between the two sets of pallet frames near the middle position and mesh with the racks on the two sets of pallet frames.

[0008] Preferably, each of the five groups of round rods consists of four rods. One of the four round rods has a threaded portion on its rear side. One of the four round rods with the threaded portion is threadedly connected to one group of cylinders. One of the four round rods with the threaded portion is movably connected to the movable frame. The other three of the four round rods are fixedly connected to the movable frame.

[0009] Preferably, the first dual-axis synchronous pulley is fixedly connected to a round rod with a threaded portion, and the other three sets of the four cylinders are slidably connected to the round rod.

[0010] Preferably, the fixing blocks and round shafts on the lower and upper fish trays are mirror-symmetrically arranged. The fixing blocks on the front and rear sides of the lower and upper fish trays are slidably arranged in two sets of corresponding sliding sleeves on the front and rear sides. The round shafts on the lower and upper fish trays are movably arranged in two sets of movable openings on the sliding sleeves. The round shafts on the lower and upper fish trays are respectively inserted into two sets of guide grooves.

[0011] Preferably, the two sets of limiting blocks on the round bar restrict the lower fish tray and the upper fish tray to their respective upper and lower sides. The rotating shaft passes through the tray frame and is fixedly connected to the rotating shaft of the second motor. The annular groove communicates with the two sets of guide grooves, and the guide grooves are inclined.

[0012] Preferably, the No. 3 dual-axis synchronous pulley, No. 3 synchronous belt, U-shaped seat, No. 2 motor, and No. 4 synchronous belt on the two sets of the pallet frame are arranged on opposite sides of the pallet frame. The rotating shaft of the No. 2 motor passes through the inside of the U-shaped seat, and the four sets of No. 4 synchronous belts are staggered on the upper and lower No. 3 dual-axis synchronous pulleys.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The movable frame can be pulled or pushed via the handle on the movable frame, and the slide bar can slide in the slide rail, making it easy to take out or remove the processed fish products from the flipping assembly. During refrigeration inside the refrigeration equipment, the No. 1 motor drives the connected No. 2 dual-axis synchronous pulley to rotate. The connected No. 2 synchronous belt drives the bottom set of No. 1 dual-axis synchronous pulleys and the connected round rods to rotate. The No. 1 synchronous belts connected to the five sets of No. 1 dual-axis synchronous pulleys drive the other four sets of No. 1 dual-axis synchronous pulleys and the four sets of connected round rods to rotate synchronously. The rotating five sets of round rods drive the threaded cylinders to move, thus... Another set of cylinders and the connected tray frame move along the cylindrical rod, while the tray frame simultaneously drives two sets of racks to rotate two sets of meshing gears. The rotating gears drive two sets of meshing racks on the other side and the tray frame to move in opposite directions along the other two sets of cylindrical rods, causing the two sets of tray frames to switch positions. This allows the processed fish products placed on the lower fish tray to be moved closer to the air outlet. The position of fish products in high and low temperature areas is switched intermittently according to needs. By adjusting the position, the products can quickly come into contact with the low temperature environment, shorten the overall refrigeration cycle, and avoid the continuous impact of a single area temperature on the freezing effect.

[0015] 2. After each switch, the No. 2 motor drives the No. 3 dual-axis synchronous pulley to rotate. The connected No. 3 synchronous belt simultaneously drives another set of No. 3 dual-axis synchronous pulleys on the tray frame, which in turn drive the connected sliding sleeves to rotate 180 degrees. The rotating sliding sleeves drive the fixed blocks and round shafts on the lower and upper fish trays to rotate. During the rotation, the upper and lower fixed blocks slide along the two sets of guide grooves and the two sets of movable openings, sliding from the guide grooves into the inner side of the annular grooves. When the two sets of round shafts slide along the two sets of guide grooves, the two sets of fixed blocks drive the lower and upper fish trays to move closer together and compress the springs, thus controlling the fish in the lower fish tray. The fish are wrapped and continuously rotated into the annular groove. After rotating 180 degrees, the upper and lower circular shafts flip over the lower and upper fish trays, and the fish products fall into the flipped upper fish tray. At this time, the compressed spring pushes the lower and upper fish trays apart under the elastic action. The two sets of circular shafts switch positions and are then bounced apart to enter the two sets of guide grooves respectively, flipping the fish products in the lower or upper fish tray. Flipping allows different sides of the fish products to alternately contact the cold environment inside the device, indirectly compensating for the shortcomings of uneven temperature inside the device. Without additional adjustments to the device, the fish products can reach a stable refrigerated state more quickly. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figures 1-8 One embodiment of the present invention provides a refrigeration device for processing sea bass, comprising a refrigeration unit 1. Slide rails 2 are fixedly installed at the four corners of the refrigeration chamber of the refrigeration unit 1. Slide strips 3 are slidably installed on the inner sides of the four sets of slide rails 2. A switching assembly 4 is installed between the four sets of slide strips 3. Five flipping assemblies 5 are installed inside the switching assembly 4. The switching assembly 4 includes a movable frame 41 fixedly installed between the four sets of slide strips 3. Five fixing plates 42 are fixedly installed inside the movable frame 41. Transmission rods 43 are rotatably installed between the five sets of fixing plates 42. Gears 44 are fixedly installed on the front and rear sides of the five sets of transmission rods 43. Five round rods 45 are installed inside the movable frame 41. Each of the five sets of round rods 45 has a No. 1 dual-shaft synchronous pulley 46 on one side. Each of the five sets of round rods 45 has two sets of pallet frames 47 movably mounted on them. Each of the two sets of pallet frames 47 has two sets of cylinders 48 fixedly mounted on opposite ends. Each of the two sets of pallet frames 47 has two sets of racks 49 fixedly mounted on opposite ends. Four sets of No. 1 synchronous belts 410 are fitted between the five sets of No. 1 dual-shaft synchronous pulleys 46. A No. 1 motor 411 is fixedly mounted on the lower side of the movable frame 41 near the No. 1 synchronous belt 410. A No. 2 dual-shaft synchronous pulley 412 is fixedly mounted on the rotating shaft of the No. 1 motor 411. A No. 2 synchronous belt 413 is fitted between the No. 2 dual-shaft synchronous pulley 412 and the lowest set of No. 1 dual-shaft synchronous pulleys 46.

[0028] The movable frame 41 is equipped with a handle. Five sets of fixed plates 42 and transmission rods 43 are arranged vertically and evenly. Each set of five fixed plates 42 consists of two plates. Two sets of gears 44 are located between two sets of pallet frames 47 near the middle and mesh with the racks 49 on the two sets of pallet frames 47. Each set of five round rods 45 consists of four rods. One of the four round rods 45 has a threaded part on its rear side. One of the four round rods 45 with a threaded part is threadedly connected to a set of cylinders 48. One of the four round rods 45 with a threaded part is movably connected to the movable frame 41. The other three of the four round rods 45 are fixedly connected to the movable frame 41. The first dual-shaft synchronous pulley 46 is fixedly connected to one of the round rods 45 with a threaded part. The other three sets of four cylinders 48 are slidably connected to the round rods 45.

[0029] The movable frame 41 and slide bar 3 can be pulled or pushed through the handle on the movable frame 41 to slide in the slide rail 2, making it easy to take out or remove the processed fish products on the flipping assembly 5. When refrigerating inside the refrigeration equipment 1, the first motor 411 drives the connected second dual-axis synchronous pulley 412 to rotate, and the connected second synchronous belt 413 drives the bottom set of first dual-axis synchronous pulleys 46 and the connected round rods 45 to rotate. The first synchronous belts 410 connected to the five sets of first dual-axis synchronous pulleys 46 drive the other four sets of first dual-axis synchronous pulleys 46 and the four sets of connected round rods 45 to rotate synchronously. The rotating five sets of round rods 45 drive the threaded cylinders 48 to move. The movement causes another set of cylinders 48 and the connected tray frame 47 to move along the round rod 45. At the same time, the tray frame 47 drives two sets of racks 49 to drive two sets of meshing gears 44 to rotate. The rotating gears 44 drive the two sets of meshing racks 49 and the tray frame 47 on the other side to move in opposite directions along the other two sets of round rods 45, so that the two sets of tray frames 47 switch positions. This allows the processed fish products placed on the lower fish tray 51 to be moved closer to the air outlet. The position of fish products in high and low temperature areas is switched intermittently according to needs. By adjusting the position, they can quickly come into contact with the low temperature environment, shorten the overall refrigeration cycle, and avoid the continuous impact of the temperature of a single area on its freezing effect.

[0030] The flipping assembly 5 includes two sets of lower fish trays 51 disposed inside the tray frame 47. An upper fish tray 52 is mirror-mounted on the inner side of the tray frame 47 near the upper side of the upper fish tray 52. ​​Fixing blocks 53 are fixedly mounted on the front and rear sides of both the lower and upper fish trays 51 and 52. A round shaft 54 ​​is fixedly mounted on each fixing block 53. A round rod 55 is movably mounted between the lower and upper fish trays 51 and 52 near the four corners. Limit blocks 56 are fixedly mounted at the upper and lower ends of each round rod 55. A spring 57 is sleeved on the outer side of the round rod 55 near the lower and upper fish trays 51 and 52. Two sets of sliding sleeves 58 are disposed on the inner walls of the front and rear sides of the tray frame 47. The inner side of the sliding sleeves 58 near the upper and lower corners... Each side has an opening 59. A rotating shaft 510 is fixedly installed inside the sliding sleeve 58. Circular grooves 511 are opened on the inner walls of the front and rear sides of the pallet frame 47 corresponding to the sliding sleeve 58. Guide grooves 512 are opened on the upper and lower sides of the circular grooves 511. Three dual-axis synchronous pulleys 513 are fixedly installed on the outer sides of the two sets of rotating shafts 510 in the pallet frame 47. A three-axis synchronous belt 514 is fitted between the two sets of three dual-axis synchronous pulleys 513. U-shaped seats 515 are fixedly installed on opposite ends of the two sets of pallet frames 47. A second motor 516 is fixedly installed on the U-shaped seat 515. Four sets of fourth-axis synchronous belts 517 are fitted between the three dual-axis synchronous pulleys 513 on the five sets of flipping components 5.

[0031] The fixing blocks 53 and the round shafts 54 on the lower fish tray 51 and the upper fish tray 52 are mirror-symmetrically arranged. The fixing blocks 53 on the front and rear sides of the lower fish tray 51 and the upper fish tray 52 are slidably disposed within two sets of sliding sleeves 58 on the front and rear sides. The round shafts 54 on the lower fish tray 51 and the upper fish tray 52 are movably disposed within two sets of movable openings 59 on the sliding sleeves 58. The round shafts 54 on the lower fish tray 51 and the upper fish tray 52 are respectively inserted into two sets of guide grooves 512. The two sets of limiting blocks 56 on the round rod 55 respectively restrict the lower fish tray 51 and the upper fish tray 52. On the upper and lower sides of the fish tray 52, the rotating shaft 510 passes through the tray frame 47 and is fixedly connected to the rotating shaft of the second motor 516. The annular groove 511 communicates with the two sets of guide grooves 512. The guide grooves 512 are inclined. The third dual-shaft synchronous pulley 513, the third synchronous belt 514, the U-shaped seat 515, the second motor 516, and the fourth synchronous belt 517 on the two sets of tray frames 47 are set on the opposite side of the tray frame 47. The rotating shaft of the second motor 516 passes through the inside of the U-shaped seat 515. The four sets of fourth synchronous belts 517 are staggered on the upper and lower third dual-shaft synchronous pulleys 513.

[0032] After each switch, the No. 2 motor 516 drives the No. 3 dual-axis synchronous pulley 513 to rotate. The connected No. 3 synchronous belt 514 simultaneously drives another set of No. 3 dual-axis synchronous pulleys 513 on the tray frame 47, which in turn drive the connected sliding sleeves 58 to rotate 180 degrees. The rotating sliding sleeves 58 drive the fixed blocks 53 and round shafts 54 on the lower fish tray 51 and the upper fish tray 52 to rotate. During the rotation, the upper and lower fixed blocks 53 slide along the two sets of guide grooves 512 and the two sets of movable openings 59, sliding from the guide grooves 512 into the inner side of the annular grooves 511. When the two sets of round shafts 54 slide along the two sets of guide grooves 512, the two sets of fixed blocks 53 drive the lower fish tray 51 and the upper fish tray 52 to move closer together and compress the spring 5. 7. Wrap the fish products in the lower fish tray 51 and continuously rotate them into the annular groove 511. After rotating 180 degrees, the upper and lower circular shafts 54 flip over the lower fish tray 51 and the upper fish tray 52, and the fish products fall into the flipped upper fish tray 52. ​​At this time, the compressed spring 57 pushes the lower fish tray 51 and the upper fish tray 52 apart under the elastic action. The two sets of circular shafts 54 switch positions and are then bounced apart and enter the two sets of guide grooves 512 respectively, flipping over the fish products in the lower fish tray 51 or the upper fish tray 52. ​​Flipping over allows different sides of the fish products to alternately contact the cold environment inside the device, indirectly making up for the shortcomings of uneven temperature inside the device. Without additional device adjustments, the fish products can reach a stable refrigerated state more quickly.

[0033] Working principle: During use, the handle on the movable frame 41 can be pulled or pushed to slide the movable frame 41 and the slide bar 3 in the slide rail 2, making it easy to take out or remove the processed fish products on the flipping assembly 5. When refrigerating inside the refrigeration equipment 1, the first motor 411 drives the connected second dual-shaft synchronous pulley 412 to rotate. The connected second synchronous belt 413 drives the bottom set of first dual-shaft synchronous pulleys 46 and the connected round rods 45 to rotate. The first synchronous belts 410 connected to the five sets of first dual-shaft synchronous pulleys 46 drive the other four sets of first dual-shaft synchronous pulleys 46 and the four sets of connected round rods 45 to rotate synchronously. The rotating five sets of round rods 45 drive the threaded cylinders 48 to move, so that... Another set of cylinders 48 and the connected tray frame 47 move along the cylindrical rod 45. Simultaneously, the tray frame 47 drives two sets of racks 49, which in turn drive two sets of meshing gears 44 to rotate. The rotating gears 44 drive two sets of meshing racks 49 and the tray frame 47 to move in opposite directions along the other two sets of cylindrical rods 45, causing the two sets of tray frames 47 to switch positions. This allows the processed fish products placed on the lower fish tray 51 to be moved closer to the air outlet. The position of fish products in high and low temperature zones is switched intermittently as needed. This position adjustment allows for rapid contact with the low-temperature environment, shortening the overall refrigeration cycle and avoiding the continuous impact of a single temperature zone on the freezing effect. Furthermore, after each switch, the second motor... 516 drives the third set of dual-axis synchronous pulleys 513 to rotate. The connected third synchronous belt 514 simultaneously drives another set of third-set dual-axis synchronous pulleys 513 on the tray frame 47, which in turn drive the connected sliding sleeves 58 to rotate 180 degrees. The rotating sliding sleeves 58 drive the fixed blocks 53 and round shafts 54 on the lower fish tray 51 and the upper fish tray 52 to rotate. During the rotation, the upper and lower fixed blocks 53 slide along the two sets of guide grooves 512 and the two sets of movable openings 59, sliding from the guide grooves 512 into the inner side of the annular grooves 511. When the two sets of round shafts 54 slide along the two sets of guide grooves 512, the two sets of fixed blocks 53 drive the lower fish tray 51 and the upper fish tray 52 to move closer together and compress the spring 57, thus affecting the lower fish tray. The fish products in tray 51 are wrapped and continuously rotated into the annular groove 511. After rotating 180 degrees, the upper and lower circular shafts 54 flip over the lower fish tray 51 and the upper fish tray 52, and the fish products fall into the flipped upper fish tray 52. ​​At this time, the compressed spring 57 pushes the lower fish tray 51 and the upper fish tray 52 apart under the elastic action. The two sets of circular shafts 54 switch positions and are then bounced apart and enter the two sets of guide grooves 512 respectively, flipping over the fish products in the lower fish tray 51 or the upper fish tray 52. ​​Flipping allows different sides of the fish products to alternately contact the cold environment inside the device, indirectly making up for the shortcomings of uneven temperature inside the device. Without additional adjustments to the device, the fish products can reach a stable refrigerated state more quickly.
