Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a thawing machine for food processing. Background Technology

[0002] Currently, existing technology discloses a thawing machine for food processing, which is a crucial step in thawing frozen meat, seafood, and other ingredients. To meet the needs of large-scale production, specialized thawing machines are often required to replace traditional manual thawing or static immersion thawing. These thawing devices are typically equipped with a feeding device to transport frozen raw materials into the thawing chamber for processing.

[0003] However, existing thawing machine feeding devices have certain limitations in their structural design. Most feeding mechanisms use a direct mechanical connection, where the drive motor or cylinder extends directly into the feeding channel via a transmission shaft to drive the baffle or screw propeller. While this design is simple, it results in the drive components, including lubricating grease and seals, coming into direct contact with food ingredients. With prolonged use, the lubricating oil in the transmission parts is prone to leakage, contaminating the food. Furthermore, the complex internal structure of the feeding channel creates numerous unsanitary areas, making daily cleaning and disinfection extremely difficult and failing to meet increasingly stringent food hygiene and safety standards. The drive modules in existing equipment are typically fixed to the machine body with multiple bolts, making disassembly cumbersome and time-consuming when deep cleaning or maintenance is required, thus impacting production efficiency.

[0004] Therefore, this utility model proposes a thawing machine for food processing to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the prior art, the feeding drive device of the food processing thawing machine usually comes into direct contact with the food, which leads to the risk of lubricating oil contamination, and the complex internal structure makes it difficult to clean thoroughly. In addition, the external drive module is cumbersome and time-consuming to disassemble and maintain. The present invention aims to provide a food processing thawing machine with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a thawing machine for food processing, including: a housing and a feed inlet fixedly connected to the top of the housing; and a discharge mechanism disposed between the housing and the feed inlet.

[0007] The unloading mechanism has a unique magnetic drive structure, which includes a motor. The drive end of the motor drives the connecting rod to rotate. A roller is fixedly connected to the outer wall of the connecting rod. The roller is slidably connected to a short groove opened in the straight rod. A long rod is fixedly connected to the outer wall of the straight rod. The long rod is slidably connected to the limiting block of the limiting component. A magnetic block one is fixedly connected to the long rod. A sliding plate is slidably connected to the bottom of the feed inlet. A magnetic block two is fixedly connected to the bottom of the sliding plate. The magnetic block one and the magnetic block two are corresponding in position and magnetically connected.

[0008] Furthermore, the motor, connecting rod, straight rod, and long rod, and other transmission components are located on the outside, while the slide plate is located inside the feed inlet. The two are connected by the magnetic attraction of the first magnetic block and the second magnetic block to achieve contactless power transmission. The motor drives the first magnetic block to reciprocate, and then the magnetic force drives the slide plate to slide back and forth on the limiting component, thereby realizing the opening and closing control of the bottom of the feed inlet.

[0009] Preferably, the structural details of the limiting component include multiple legs for supporting the feed inlet and a long plate fixedly connected to the top of the legs. The legs provide a stable support platform for the feed inlet and also limit the installation space of the structure below. The slide plate is restricted to sliding on the top of the long plate and inside the legs. The inner sidewall of the legs forms the physical boundary of the slide plate, thereby limiting the sliding range of the slide plate and preventing it from derailing.

[0010] Preferably, the limiting component further includes a limiting plate fixedly connected to the outer wall of the support leg, and a spring. One end of the spring is fixed to the outer wall of the skateboard, and the other end is fixed to the outer wall of the support leg near the limiting plate. The spring can not only buffer the impact force when the skateboard moves to the limit position, but also assist the skateboard in resetting during the magnetic drive gap, thereby improving the stability of the movement.

[0011] Preferably, when the connecting rod rotates, it drives the roller to rotate. The roller slides in the short groove and drives the straight rod and the long rod to perform linear reciprocating motion. This crank-slider type motion conversion mechanism can efficiently and stably convert the rotational motion of the motor into the linear reciprocating motion required by the long rod, and it has a compact and durable structure.

[0012] Preferably, the device further includes a disassembly mechanism located on the outer wall of the housing. The disassembly mechanism includes a disc, and a connecting plate is fixedly extended from the outer wall of the disc. The connecting plate serves as an installation interface for modular components. Its inner wall has a sliding groove and a limiting groove communicating with the sliding groove. The disassembly mechanism also includes a turntable, and a bent L-shaped block is fixedly connected to the outer wall of the turntable. The bent L-shaped block is used to slide along the sliding groove and rotate to the limiting groove to restrict the connecting plate from leaving the turntable, thereby realizing rapid rotation locking and disassembly.

[0013] Preferably, a handle is fixedly connected to the turntable, which is used to facilitate the operator to manually drive the turntable and the curved L-shaped block to rotate, providing a good human-computer interaction experience.

[0014] Preferably, the interior of the housing is provided with a defrosting assembly for processing materials. The defrosting assembly may specifically include a spray pipe installed on the top of the inner wall of the housing or a heating pipe installed on the bottom of the inner wall of the housing, so as to meet the defrosting process requirements of different ingredients.

[0015] This utility model has the following beneficial effects: 1. This utility model uses a motor to drive a connecting rod assembly in the unloading mechanism to drive a magnetic block to reciprocate. The magnetic force penetrates the isolation wall and attracts the sliding plate inside the feed inlet to slide synchronously. This solves the problems of lubricant contamination risk and cleaning difficulties in the prior art where the feed drive component directly contacts the food. It achieves the technical effect of physically isolating the power source from the food processing area, ensuring food hygiene and safety, and facilitating internal cleaning.

[0016] 2. This utility model, by setting a limiting component in conjunction with a magnetically driven slide plate, uses the support legs to limit the slide plate's travel and combines the buffering and resetting effect of the spring, solves the problem of low feeding control accuracy in the prior art, which easily leads to material accumulation and blockage. It achieves the technical effect of enabling the bottom of the feed inlet to open and close stably as needed, realizing automated quantitative feeding, and improving the efficiency of thawing processing.

[0017] 3. This utility model, by setting a rotating buckle-type disassembly mechanism, uses a bent L-shaped block to rotate along the slide groove into the limiting groove to achieve locking, which solves the problem that the external drive module is usually fixed with bolts in the prior art, resulting in cumbersome and time-consuming disassembly and maintenance. It achieves the technical effect of quickly completing modular assembly and disassembly without the need for additional tools, greatly improving the convenience and flexibility of equipment maintenance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figures 1 to 5 This utility model provides a food processing thawing machine, which aims to solve the structural defects of existing food thawing equipment, such as the lack of quantitative control in the feeding mechanism leading to material accumulation, and the risk of contamination and difficulty in cleaning due to direct contact between the drive components and food.

[0022] like Figure 1As shown, the device includes a housing 1 serving as the mounting base and a feed inlet 2 fixedly connected to the top of the housing 1. The housing 1 contains a defrosting assembly for defrosting incoming materials. Specifically, the defrosting assembly can be a spray pipe installed on the top of the inner wall of the housing 1 for water bath defrosting, or a heating pipe installed on the bottom of the inner wall of the housing 1 for heating defrosting. The housing 1 serves as the main supporting structure of the entire device, providing a closed space for subsequent material processing. The feed inlet 2, in a funnel or box shape, is fixed above the housing 1 for feeding frozen meat or ingredients to be defrosted. A discharge mechanism 3 is provided between the housing 1 and the feed inlet 2 to control the material's falling rhythm. A disassembly mechanism 4 is provided on the outer wall of the housing 1 for easy modular assembly and maintenance. Through the organic combination of these components, a food processing device integrating automatic quantitative feeding and defrosting functions is formed.

[0023] Reference Figure 1 and Figure 2 The unloading mechanism 3 mainly consists of a power source and a linkage transmission assembly. The motor 31 is fixedly installed on the outer wall of the housing 1 as the power output end. The drive shaft end of the motor 31 is fixedly connected to a connecting rod 32. The outer wall of the connecting rod 32 away from the motor 31 is rotatably connected to a roller 33. At the same time, a straight rod 34 is provided on the side of the roller 33. The surface of the straight rod 34 has a short groove 395 in the vertical direction. The roller 33 is slidably embedded in the short groove 395. When the motor 31 starts and drives the connecting rod 32 to rotate, the roller 33 slides up and down in the short groove 395 and pushes the straight rod 34 to reciprocate in the horizontal direction. The outer wall of the straight rod 34 is fixedly connected to an inwardly extending long rod 35. In order to ensure the stability of the motion trajectory, the long rod 35 slides through the limiting block 394 fixedly installed on the outer wall of the housing 1. The limiting block 394 is part of the limiting assembly 39 and plays a guiding and supporting role.

[0024] A magnetic block 36 is fixedly connected to the end of the long rod 35 away from the straight rod 34, while a sliding plate 38 for blocking or opening the feeding channel is slidably connected to the bottom inner wall of the feed inlet 2. A magnetic block 37 is fixedly connected to the bottom of the sliding plate 38 at the corresponding position. The magnetic blocks 36 and 37 are vertically aligned and coupled by strong magnetic attraction. In this way, when the long rod 35 on the outside moves back and forth, it can drive the sliding plate 38 inside the feed inlet 2 to move back and forth synchronously through magnetic force, thereby realizing the alternating opening and closing of the bottom of the feed inlet 2 and quantitative feeding.

[0025] The limiting component 39 also includes multiple legs 396 fixedly connected to the top of the housing 1. A long plate 392 is fixedly connected to the top of the legs 396. The slide plate 38 is slidably connected to the top surface of the long plate 392 and located within the space enclosed by the side wall of the feed port 2. In order to prevent the slide plate 38 from moving out of position and to assist in resetting, the limiting component 39 also includes a limiting plate 393 fixedly connected to the outer wall of the legs 396, and a spring 391 connected between the outer wall of the slide plate 38 and the outer wall of the legs 396. One end of the spring 391 is fixed to the side wall of the slide plate 38, and the other end is fixed to the leg 396 near the limiting plate 393. The sliding range of the slide plate 38 is limited by the legs 396, and the spring 391 provides a buffering force to ensure that the feeding process is smooth and stable.

[0026] Reference Figure 4 and Figure 5 The disassembly mechanism 4 of the outer wall of the housing 1 adopts a rotary snap-on structure. The disassembly mechanism 4 includes a disc 47 fixed to the side of the module to be disassembled. A long strip-shaped connecting plate 46 is fixed to the outer wall of the disc 47 along the tangential direction. A sliding groove 45 extending along an arc trajectory is opened on the inner side wall surface of the connecting plate 46, and a limiting groove 44 is provided at the end of the sliding groove 45 and communicates with it. The groove depth or groove width of the limiting groove 44 forms an angle difference with the sliding groove 45 to play a limiting and locking role.

[0027] In conjunction with the locking action of the connecting plate 46, a turntable 42 is rotatably connected to the corresponding position on the outer wall of the housing 1. A curved L-shaped block 43 that rotates coaxially with the turntable 42 is fixedly connected to the outer peripheral side wall of the turntable 42. At the same time, a handle 41 that is easy to hold and operate is fixedly connected to the center of the end face of the turntable 42 away from the housing 1. When the connecting plate 46 overlaps and fits against the outer wall of the turntable 42, the turntable 42 is rotated by rotating the handle 41, so that the curved L-shaped block 43 can be accurately guided into the slide groove 45 and slide, and finally rotated and locked into the limiting groove 44. The mechanical engagement between the curved L-shaped block 43 and the limiting groove 44 restricts the connecting plate 46 from disengaging from the turntable 42, thereby realizing modular quick fixing and disassembly.

[0028] The defrosting component inside the housing 1 can be configured in various ways depending on different processing requirements. For scenarios requiring rapid water bath defrosting, the defrosting component is a spray pipe fixedly installed on the top of the inner wall of the housing 1. The spray pipe is connected to an external circulating water pump through a pipeline. It accelerates heat exchange by uniformly spraying warm water onto the surface of the material. For scenarios requiring constant temperature defrosting, the defrosting component is a heating pipe fixedly installed on the bottom of the inner wall of the housing 1. The heating pipe heats the water medium or air inside the housing 1, thereby creating a suitable defrosting environment.

[0029] The width of the slide plate 38 is designed to be equal to or slightly larger than the opening width at the bottom of the feed inlet 2, and the sliding stroke of the slide plate 38 on the long plate 392 covers the opening area at the bottom of the feed inlet 2. This size matching ensures that when the slide plate 38 moves to the closed position under the drive of the magnetic block 37, it can completely block the bottom of the feed inlet 2 to cut off the material flow. When the slide plate 38 moves to the open position, the material in the feed inlet 2 can fall smoothly into the housing 1 under the action of gravity. With the continuous rotation of the motor 31, intermittent quantitative automatic feeding is realized.

[0030] The implementation principle of this application embodiment is as follows: When using the equipment to process food thawing, the operator first puts the frozen material into the feed inlet 2, and then starts the motor 31 of the unloading mechanism 3. The drive end of the motor 31 rotates and drives the connecting rod 32 to rotate. The roller 33 fixed at the end of the connecting rod 32 then makes a circular motion. Since the roller 33 is embedded in the short groove 395 on the surface of the straight rod 34, while the roller 33 slides up and down in the short groove 395, it will apply a horizontal thrust to the straight rod 34, forcing the straight rod 34 and the long rod 35 fixedly connected to it to make horizontal reciprocating linear motion under the guidance of the limiting block 394.

[0031] As the long rod 35 moves, the magnetic block 36 fixed at its end moves synchronously. Utilizing magnetic coupling, the magnetic block 36 attracts and drives the internal magnetic block 37 through the feed inlet 2 or the wall of the housing 1, thereby driving the slide plate 38 to slide back and forth on the top of the long plate 392. When the slide plate 38 moves to one side and opens the bottom of the feed inlet 2, the material falls into the housing 1 under the action of gravity for thawing. When the slide plate 38 moves in the opposite direction and blocks the bottom of the feed inlet 2, the material flow is cut off. During this process, the slide plate 38 is restricted to move within a specified range by the support leg 396. When the slide plate 38 moves to the end of its stroke, the spring 391 is deformed by force, which, together with the limit plate 393, plays a role in buffering and assisting in reset, effectively preventing the slide plate 38 from falling off due to inertia or being hit too hard.

[0032] When modular assembly or disassembly and cleaning of the equipment is required, the operator rotates the handle 41 of the disassembly mechanism 4 to drive the turntable 42 and the bent L-shaped block 43 to rotate, so that the bent L-shaped block 43 is aligned with the inlet of the slide groove 45 on the connecting plate 46 and slides in until the bent L-shaped block 43 rotates to the limit groove 44 to form a lock. At this time, the connecting plate 46 is locked by the turntable 42, and the module is fixed. Rotating the handle 41 in the opposite direction causes the bent L-shaped block 43 to exit the limit groove 44 and the slide groove 45, so that the connecting plate 46 can be separated from the turntable 42.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
