Description

Technical Field

[0001] The present invention relates to the technical field of quick-frozen food processing, and particularly to a packaging and transportation device and method for quick-frozen food processing. Background Technique

[0002] In the processing and production process of quick-frozen foods, a scientific and efficient technological process is crucial for ensuring product quality and production efficiency. Its conventional process covers key links such as raw material processing, ingredient preparation, precooking, cooling and quick-freezing, packaging, and cold storage in the warehouse.

[0003] Among them, the cooling and quick-freezing link is particularly crucial. Usually, the processed food is conveyed into the quick-freezing machine by a conveyor belt for rapid cooling and quick-freezing treatment, and then packaged. In this process, the state of the food on the conveyor belt has a direct impact on the quick-freezing effect. If the food is piled up and enters the quick-freezing machine, the following problems will occur: on the one hand, the externally piled-up food is easily adhered to each other after quick-freezing and is difficult to separate in the subsequent packaging link, seriously affecting the packaging efficiency and product appearance; on the other hand, the part at the bottom being pressed is difficult for cold air to fully contact due to being squeezed, resulting in insufficient freezing and presenting a wet and soft state, which not only does not meet the product quality standards but also brings great difficulties to the subsequent distribution and packaging work.

[0004] Currently, the industry generally adopts the method of installing a rotary rake roller on the conveyor belt to solve the problem of food accumulation. Through the rotation of the rake roller, the food piled up on the conveyor belt is scattered and spread out. However, this traditional treatment method has many drawbacks. Firstly, the spreading action of the rake roller is relatively intense, and it is extremely easy to cause food to splash during the operation, not only causing material waste but also polluting the production environment and increasing the cleaning cost. Secondly, during the process of scattering the food, if some food accidentally gets stuck in the gaps of the conveyor belt, it is often missed. Over time, these missed foods will continuously accumulate and breed bacteria, posing a serious threat to the production quality. Thirdly, foods such as carrot grains and mushroom pieces are very easy to adhere to the rake roller. Due to the complex structure of the rake roller, it is extremely difficult to clean manually, not only consuming a large amount of time and manpower but also affecting the continuity of production and reducing the production efficiency. Summary of the Invention

The direction of the horizontal plate is perpendicular to the direction of the conveyor belt, and rake rod assemblies are symmetrically installed on both sides of the horizontal plate;

[0012] Rollers are provided at the bottom of the movable frame, and the rollers are in contact with the fixed frame;

[0013] In the conveying direction of the conveyor belt, the outer diameter of the movable frame matches the inner diameter of the fixed frame.

[0014] As a further solution of the present invention: The rake rod assembly is composed of a plurality of rake rod units, and each rake rod unit is composed of a rake rod and an electric telescopic rod. The rake rod is L-shaped, one end of the rake rod is fixed to the telescopic end of the electric telescopic rod, and the other end is bent downward to be close to the upper surface of the conveyor belt;

[0015] The end of the electric telescopic rod far from the rake rod is fixed on the horizontal plate, and the telescopic end of the electric telescopic rod connecting the rake rod penetrates through the movable frame.

[0016] As a further solution of the present invention: Connecting blocks are fixedly installed on both the left and right sides outside the fixed frame, and the connecting blocks are fixedly connected to the lifting blocks of the lifting mechanism at the corresponding positions;

[0017] Inside the fixed frame, a cam is arranged on the left side and an electromagnet assembly is arranged on the right side. The cam is in contact with the surface of the movable frame, and the cam is driven by a rotating column to rotate;

[0018] The electromagnet assembly includes two electromagnets. One electromagnet is fixedly installed on the inner side wall of the fixed frame, and the other electromagnet is fixedly installed on the outer side wall of the movable frame, and the positions of the two electromagnets correspond to each other.

[0019] As a further solution of the present invention: the lift of the cam is set according to the spacing between adjacent rake rod units, and an anti-collision cushion is provided on the side of the movable frame in contact with the cam.

[0020] As a further solution of the present invention: a chute is provided on the fixed seat, slide rails are installed on both sides of the chute in the vertical direction, the lifting block is located in the chute and is slidably connected to the slide rails;

[0021] A lead screw is rotatably installed in the middle of the chute, the lead screw vertically penetrates the lifting block and is threadedly connected to the lifting block, and the lead screw is driven to rotate by a motor.

[0022] As a further solution of the present invention: a spherical end is provided at one end of the rake rod close to the conveyor belt.

[0023] As a further solution of the present invention: the baffles are arranged along the direction of the conveyor belt, and the baffles are located within the two side edges of the conveyor belt;

[0024] Adjusting rods are provided on the baffles, adjusting seats are provided on the frame at the corresponding positions of the adjusting rods, the adjusting seats are fixedly installed on the frame, and the adjusting rods pass through the adjusting seats and are locked by nuts.

[0025] 11. As a further solution of the present invention: the lifting mechanism is located outside the baffle, and the raking mechanism is located inside the baffle;

[0026] The baffle is provided with an opening groove through which the connecting block can pass at the corresponding positions of the lifting mechanism and the raking mechanism.

[0027] A method for using a packaging and transportation device for frozen food processing, using the packaging and transportation device for frozen food processing as described above, includes the following steps:

[0028] S1: The raking mechanism is started. Under the action of the electric telescopic rod, the rake rod moves back and forth. At the same time, the cam rotates, pushing the movable frame to perform a uniform and smooth reciprocating motion in the left-right direction. At the same time, the lead screw drives the lifting block to perform a reciprocating motion up and down, and the raking mechanism follows to perform a reciprocating motion up and down;

[0029] S2: Pour the food to be frozen at the starting end of the conveyor belt. The food is conveyed from the starting end to the end along the conveyor belt, and will pass through the raking mechanism and the freezer in sequence during the process;

[0030] S3: When the food passes through the raking mechanism along the conveyor belt, the moving rake rod can fully contact the food, evenly rake and disperse the piled-up food;

[0031] S4: The dispersed food smoothly enters the freezer and is quickly frozen in the freezer to complete the quick-freezing process, meeting the requirements of food preservation and storage, and then entering the next process;

[0032] S5: After a batch of food has been conveyed, to ensure the hygiene of the equipment and the quality of subsequent production, the conveyor belt needs to be cleaned. At this time, the electric telescopic rod, the cam, and the lifting block stop moving, and the electromagnet assembly is activated. By adjusting the current intensity and direction of the two electromagnets in the electromagnet assembly, a continuously changing repulsive force and attractive force are generated to drive the movable frame to perform high-speed reciprocating motion. The powerful vibration force generated by this motion can quickly shake off the remaining food on the rake rod, achieving efficient cleaning of the rake rod and facilitating subsequent reuse.

[0033] Compared with the existing technology, the advantages of the present invention are as follows:

[0034] 1. The rake rod can move coordinately in three dimensions: up and down, left and right, and front and back. The movement path is more complex and flexible. Compared with traditional equipment that only works in a single dimension or a simple motion mode, the present invention has a better effect of dispersing food. Especially in the left and right directions, the present invention uses a cam to precisely control the rake rod to perform small-amplitude uniform and smooth swinging. On the one hand, the small-amplitude swing is sufficient to effectively rake apart the piled-up food in the left and right directions, ensuring that the food is evenly spread on the conveyor belt; on the other hand, the uniform and smooth swinging characteristic avoids the problem of food splashing caused by too large a swing stroke or too violent a swing amplitude, greatly reducing the risk of food getting stuck in the conveyor belt gap.

[0035] 2. After the food conveying work is completed and the conveyor belt needs to be cleaned, only by turning on the electromagnet assembly, the movable frame will quickly enter the high-speed reciprocating motion state. This high-speed reciprocating motion can generate a powerful vibration force, effectively shaking off the remaining food on the rake rod. Compared with the traditional manual cleaning method, the automatic shaking-off design of the present invention greatly improves the cleaning efficiency and saves a large amount of labor and time costs.

Specific embodiments

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] Refer to Figures 1-11 , a packaging and transportation device for quick-frozen food processing, mainly composed of a conveyor belt 1, a frame 2, a lifting mechanism 3, a raking mechanism 4 and a quick-freezing machine 21.

[0050] The conveyor belt 1 is installed on the frame 2. Baffles 11 are provided on both sides of the conveyor belt 1. The baffles 11 are arranged along the running direction of the conveyor belt 1, and the baffles 11 are located within the edges on both sides of the conveyor belt 1. The function of the baffles 11 is to limit the food on the conveyor belt 1, preventing the food from falling or falling into the gaps at the edges of the conveyor belt 1 during the conveying process. The bottom of the baffle 11 is close to the conveyor belt 1, and the part of the baffle 11 close to the conveyor belt 1 can be made of rubber material.

[0051] Refer to Figure 2, an adjusting rod 111 is provided on the baffle 11, and an adjusting seat 112 is provided on the frame 2 at the corresponding position. The adjusting rod 111 passes through the adjusting seat 112 and is locked with a nut. By loosening the nut, adjusting the position of the adjusting rod 111 and then locking the nut, the distance between the two side baffles 11 can be adjusted, thereby limiting the spreading range of the food to meet the packaging and transportation requirements of different frozen foods. A quick-freezing machine 21 is fixedly installed above the middle section of the conveyor belt 1 on the frame 2, which is used to quickly freeze the dispersed food to meet the food freshness and storage requirements.

[0052] Two lifting mechanisms 3 are in a group and are symmetrically arranged on both sides of the conveyor belt 1. The raking mechanism 4 straddles the conveyor belt 1, and both sides are fixedly connected to the lifting blocks 32 of a group of lifting mechanisms 3 through connecting blocks 413 respectively.

[0053] Refer to Figures 3-10 , the lifting mechanism 3 includes a fixed seat 31, a lifting block 32 and a lead screw 33. The fixed seat 31 is fixedly installed on the frame 2, and a chute 311 is provided on it. Slide rails 312 are installed on both sides of the chute 311 in the vertical direction. The lifting block 32 is located in the chute 311 and is slidably connected to the slide rails 312 to ensure that the lifting block 32 can move up and down stably. A lead screw 33 is rotatably installed in the middle of the chute 311. The lead screw 33 vertically penetrates the lifting block 32 and is threadedly connected to it, and is driven by a motor to rotate. When the motor drives the lead screw 33 to rotate forward or backward, the rotation of the lead screw 33 is converted into the up-and-down linear motion of the lifting block 32, thereby realizing the adjustment of the height of the raking mechanism 4 to adapt to frozen foods of different thicknesses.

[0054] The raking mechanism 4 includes a fixed frame 41, a movable frame 42 and a rake rod assembly 43. The movable frame 42 is located inside the fixed frame 41, and both sides are connected to the fixed frame 41 through springs 44. The connecting blocks 413 on the left and right sides outside the fixed frame 41 are connected to the lifting blocks 32, so that the raking mechanism 4 can move up and down with the lifting mechanism 3. The baffle 11 is provided with an opening groove 113 for the connecting block 413 to pass through at the corresponding positions of the lifting mechanism 3 and the raking mechanism 4.

[0055] Refer to Figures 3-8 , a cam 411 is arranged on the left side inside the fixed frame 41. The cam 411 is in contact with the movable frame 42, and an anti-collision soft pad is provided on the side of the movable frame 42 in contact with the cam 411 to reduce the collision wear and noise between the cam 411 and the movable frame 42. The cam 411 is driven by a rotating column 4111 to rotate, and its lift is set according to the distance between adjacent rake rod units 431. For example, if the lift of the cam 411 is the same as the distance between adjacent rake rod units 431, then the amplitude of the cam 411 pushing the movable frame 42 to swing is the size of the distance between the rake rod units 431.

[0056] It should be noted here that the reason for setting the cam 411 to push the movable frame 42 to swing, rather than using a common linear motor, cylinder, or telescopic rod, is that the swing amplitude needs to be strictly controlled here, and the swing action needs to be ensured to be stable and smooth. The cam 411 controls the left-right swing of the movable frame 42 (rake rod 432). On both sides of the conveyor belt 1 in the left-right direction, there are baffles 11. If the placement amplitude is too large or the swing action is violent, it is very easy for food (such as corn kernels, carrot grains, mushroom pieces, etc.) to splash onto the baffle 11 or even fall into the gap at the edge of the conveyor belt. When the cam 411 of the present application rotates, it can push the movable frame 42 to swing smoothly at a small amplitude at a constant speed, avoiding food splashing caused by too large a swing amplitude.

[0057] The movable frame 42 is in the shape of a square box, with a transverse plate 421 fixedly installed inside. The direction of the transverse plate 421 is perpendicular to the direction of the conveyor belt 1. Rake rod assemblies 43 are symmetrically installed on both sides of the transverse plate 421. The bottom of the movable frame 42 is provided with rollers 422, and the rollers 422 are in contact with the fixed frame 41, which play a role in supporting and reducing friction when the movable frame 42 moves, and at the same time ensure the smooth movement of the movable frame 42 within the fixed frame 41; in the conveying direction of the conveyor belt 1, the outer diameter of the movable frame 42 matches the inner diameter of the fixed frame 41, enabling the movable frame 42 to swing left and right stably within the fixed frame 41.

[0058] Refer to Figures 3-9 , the rake rod assembly 43 is composed of a number of rake rod units 431. Each rake rod unit 431 is composed of a rake rod 432 and an electric telescopic rod 433. The rake rod 432 is L-shaped, with one end fixed to the telescopic end of the electric telescopic rod 433 and the other end bent downward. A spherical end 4321 is provided at the end close to the conveyor belt 1 (the spherical end 4321 can be fixed or rotatably installed at the end of the rake rod 432). In this way, when raking the food flat, it can effectively rake the food and avoid scratching the conveyor belt 1.

[0059] One end of the electric telescopic rod 433 away from the rake rod 432 is fixed on the transverse plate 421, and its telescopic end connecting the rake rod 432 penetrates the movable frame 42. After the electric telescopic rod 433 is started, it can drive the rake rod 432 to move back and forth. It should be noted here that the fixed frame 41 is designed with an opening at the corresponding position of the rake rod 432 to let the rake rod 432 protrude, and enough space for the left-right swing of the rake rod 432 needs to be left.

[0060] An electromagnet assembly 412 is provided on the right side inside the fixed frame 41. The electromagnet assembly 412 includes two electromagnets, which are respectively fixedly installed on the inner side wall of the fixed frame 41 and the outer side wall of the movable frame 42, and their positions correspond to each other. When a batch of food is frozen and the equipment needs to be cleaned, by adjusting the current intensity and direction of the two electromagnets in the electromagnet assembly 412, and using the changing repulsive force and suction force between them, the movable frame 42 is driven to perform high-speed reciprocating motion. The powerful vibration force generated by this motion can quickly shake off the remaining food on the rake rod 432, achieving efficient cleaning of the rake rod 432 and facilitating subsequent reuse.

[0061] Further explanation, the above-mentioned fixed connection, unless otherwise clearly stipulated and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0062] A method of using a packaging and transportation device for frozen food processing, using the above-mentioned packaging and transportation device for frozen food processing, includes the following steps:

[0063] S1: The raking mechanism 4 is started. Under the action of the electric telescopic rod 433, the rake rod 432 moves back and forth. At the same time, the cam 411 rotates, pushing the movable frame 42 to perform small-amplitude uniform and smooth reciprocating motion in the left-right direction. Meanwhile, the lead screw 33 drives the lifting block 32 to perform up and down reciprocating motion, and the raking mechanism 4 moves up and down accordingly;

[0064] S2: Pour the food to be frozen onto the starting end of the conveyor belt 1. The food is conveyed from the starting end to the end along the conveyor belt 1, and will successively pass through the raking mechanism 4 and the quick-freezing machine 21 during the process;

[0065] S3: When the food passes through the raking mechanism 4 along the conveyor belt 1, the moving rake rod 432 can fully contact the food, evenly rake and disperse the piled-up food;

[0066] S4: The dispersed food smoothly enters the quick-freezing machine 21 and is quickly frozen inside the quick-freezing machine 21 to complete the quick-freezing process, meeting the requirements of food preservation and storage, and then entering the next process;

[0067] S5: After a batch of food is conveyed, to ensure the hygiene of the equipment and the quality of subsequent production, the conveyor belt 1 needs to be cleaned. At this time, the electric telescopic rod 433, the cam 411, and the lifting block 32 stop moving, and the electromagnet assembly 412 is started. By adjusting the current intensity and direction of the two electromagnets in the electromagnet assembly 412, a continuously changing repulsive force and suction force are generated to drive the movable frame 42 to perform high-speed reciprocating motion. The powerful vibration force generated by this motion can quickly shake off the remaining food on the rake rod 432, achieving efficient cleaning of the rake rod 432 and facilitating subsequent reuse.

[0068] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.

At this time, the electric telescopic rod (433), the cam (411) and the lifting block (32) stop moving, and the electromagnet assembly (412) is started. By adjusting the current intensity and direction of the two electromagnets in the electromagnet assembly (412), the repulsive force and the attractive force are continuously changed, and the movable frame (42) is driven to reciprocate at high speed, so that the food remaining on the rake rod (432) is quickly shaken off.
