Description

Technical Field

[0001] This utility model belongs to the technical field of food frying machines, specifically relating to a stacked frame frying machine. Background Technology

[0002] For some fried foods that require shaping during frying, it's common to secure them in frying trays to prevent them from rolling and bumping during the frying process. However, this method is difficult to implement in traditional continuous mesh fryers. Therefore, for these foods, a common practice is to stack frying trays in a hanging frame, then place the frame into the frying chamber of the fryer for frying. After frying, the hanging frame is removed, and the next stacked frame is placed into the frying chamber for frying. The drawback of this method is the poor continuity of the frying process, thus limiting production efficiency. Utility Model Content

[0003] This utility model provides a stacked frame fryer, which aims to improve the continuity of operation of the hanging frame frying method, thereby improving production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stacked-frame fryer is provided, including a frame, multiple hanging frames, a fryer body mounted on the frame, and two elevators; the fryer body is located between the two elevators; a horizontal conveying mechanism is horizontally arranged on the top of the fryer body, the horizontal conveying mechanism having multiple conveying stations that circulate sequentially from the first end to the second end of the fryer body, each conveying station being suitable for supporting and driving the hanging frames to move from the first end to the second end; the frame outside the two ends of the fryer body forms a frame inlet station and a frame outlet station suitable for placing the hanging frames; the elevators are horizontally slidably connected to the frame, and a telescopic drive component is connected between the elevators and the frame; the elevators are used to grab and drive the hanging frames to rise and fall, and to transfer the hanging frames in conjunction with the horizontal movement driven by the telescopic drive component.

[0005] In one possible implementation, the top surfaces on both sides of the blaster body form track surfaces, and a lifting shaft suitable for the hoist to grab is horizontally inserted through the top of the lifting frame. Both ends of the lifting shaft are equipped with rollers for rolling the track surfaces.

[0006] In some embodiments, at least two lifting shafts are spaced apart at the top of the lifting frame along the extension direction of the track surface, and each lifting shaft has a roller at its end.

[0007] For example, the horizontal conveying mechanism includes two closed-loop conveyor chains and a drive assembly for driving the two closed-loop conveyor chains to operate synchronously; the closed-loop conveyor chains have conveying sections that slide on a track surface; each link of the closed-loop conveyor chain is provided with a clamping plate, and a groove suitable for the hanging shaft to be engaged is formed between the clamping plates of adjacent links, and the grooves on the two conveying sections that are aligned with each other together form a conveying station.

[0008] For example, the driver components include: The drive shaft is rotatably connected to one end of the fryer body, and both ends are fitted with drive sprockets; The passive shaft is rotatably connected to the other end of the blaster body, and both ends are fitted with passive sprockets; The conveyor motor is located on the fryer body and its output end is connected to the drive shaft; Two closed-loop conveyor chains are respectively located on corresponding active and passive sprockets.

[0009] In one possible implementation, the hoist includes: The gantry frame is horizontally and slidably connected to the frame at the bottom and connected to the output end of the telescopic drive component. Two rotary drive chains are respectively installed on two columns of the gantry frame, and the two rotary drive chains have a lifting section that moves synchronously from bottom to top in the vertical direction; The lifting drive unit is located on the gantry frame, and its output end is connected to two rotary drive chains. The fork arm has one end that slides vertically to two columns, and the other end has a groove suitable for the insertion of the lifting shaft. The middle part of the fork arm is connected to the lifting section of two rotary drive chains.

[0010] In some embodiments, both columns are provided with vertical guide grooves; the end of the fork arm away from its groove is connected to a first shaft, and the two ends of the first shaft are respectively fitted with first guide wheels rolled in the vertical guide grooves; a second shaft is provided below the first shaft, the second shaft is connected to the first shaft through a connecting rod, and the two ends of the second shaft are respectively fitted with second guide wheels rolled in the vertical guide grooves.

[0011] For example, the lifting drive includes: The drive shaft is rotatably connected to the top of the gantry frame, and drive sprockets are fitted at both ends; The driven shaft is rotatably connected to the bottom of two columns at both ends, and each end is fitted with a driven sprocket. The two driven sprockets correspond one-to-one with the two drive sprockets and are aligned vertically. The lifting motor is fixed to the gantry frame and its output end is connected to the drive shaft. Two rotary drive chains are respectively located on the corresponding drive sprocket and driven sprocket.

[0012] For example, the frame is provided with horizontal guide grooves on both sides of the frame infeed station and the frame outfeed station. The lower ends of the two columns are provided with guide wheel sets rolled in the horizontal guide grooves. The guide wheel sets include multiple third guide wheels that are spaced apart along the extension direction of the horizontal guide grooves.

[0013] In some embodiments, oil receiving trays are provided at both the infeed and outfeed stations.

[0014] The beneficial effects of the stacked-frame fryer provided by this utility model are as follows: Compared with the prior art, the stacked-frame fryer of this utility model, by setting lifting machines that can slide horizontally on the frame at both ends of the fryer body, can place the hanging frame at the frame feeding station during the frying operation. Then, the frying trays containing the food to be fried are stacked layer by layer in the hanging frame. After the placement is completed, the lifting machine near the frame feeding station picks up the hanging frame and lifts it to a height higher than the fryer body. Then, the telescopic drive component drives the lifting machine to move above the first end of the fryer body. After the movement is in place, the lifting machine drives the hanging frame to move upwards. The frame descends to the conveyor station at the first end and resets after being released, ready for the transfer of the next frame. Meanwhile, the food is fried as the frame on the conveyor station moves from the first end to the second end. The elevator near the second end uses its own lifting action and its horizontal movement driven by the telescopic drive to transfer the frame that has reached the second end from the conveyor station to the frame exit station. Then it grabs the next frame that has reached the second end, thus realizing continuous frying operation and improving the processing efficiency of fried foods that need to be constrained and shaped using frying pans.

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] It should be noted that when an element is referred to as being "set on" or "connected to" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "upper," "lower," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0019] Please refer to the following: Figures 1 to 9The present invention provides a description of a stacked-frame fryer. The stacked-frame fryer includes a frame 10, multiple hanging frames 20, a fryer body 30 mounted on the frame 10, and two elevators 40. The fryer body 30 is located between the two elevators 40. A horizontal conveying mechanism 50 is horizontally arranged on the top of the fryer body 30. The horizontal conveying mechanism 50 has multiple conveying stations that circulate sequentially from the first end 301 to the second end 302 of the fryer body 30. Each conveying station is suitable for supporting and driving the hanging frames 20 to move from the first end 301 to the second end 302. The frame 10, located outside both ends of the fryer body 30, forms a frame-entry station 101 and a frame-exit station 102 suitable for placing the hanging frames 20. The elevators 40 are horizontally slidably connected to the frame 10, and a telescopic drive member 60 is connected between them. The elevators 40 are used to grab and drive the hanging frames to rise and fall, and, in conjunction with the horizontal movement driven by the telescopic drive member 60, transfer the hanging frames 20.

[0020] It should be noted that the fryer body 30 in this embodiment can adopt the structural form of the prior art. For example, it includes an outer shell, and a horizontally extending inner liner is provided inside the outer shell to contain frying oil. The frying oil can be quantitatively added to the inner liner and heated by the built-in electric heating tube. The frying oil can also be circulated to meet the continuous filtration and purification requirements of the frying oil. This method can be heated by the built-in electric heating tube, or it can be based on the external oil heater to externally heat the circulating frying oil, or it can be a method in which the built-in electric heating tube and the external oil heater are used to heat the frying oil together.

[0021] It should be understood that the fryer body 30 for continuous frying has a large length-to-width ratio. Typically, its length is about ten meters and its width is about one meter. The number of hanging frames 20 that can perform frying operations at the same time can be determined based on the length of the fryer body 30.

[0022] Compared with the prior art, the stacked-frame fryer provided in this embodiment has a unique feature: by setting lifting mechanisms 40 that can slide horizontally on the frame 10 at both ends of the fryer body 30, the hanging frame 20 can be placed on the frame feeding station 101 during the frying operation. Then, the frying trays containing the food to be fried are stacked layer by layer inside the hanging frame 20. After the placement is completed, the lifting mechanism 40 near the frame feeding station 101 picks up the hanging frame 20 and lifts it to a height higher than the fryer body 30. Then, the telescopic drive component 60 drives the lifting mechanism 40 to move upwards towards the first end 301 of the fryer body 30. After the movement is completed, the lifting mechanism 40 lowers the hanging frame 20 to the first end. At the conveying station 301, after releasing the hanging frame 20, it resets to prepare for the transfer of the next hanging frame 20; at the same time, the food is fried as the hanging frame 20 on the conveying station moves from the first end 301 to the second end 302. The elevator 40 near the second end 302 transfers the hanging frame 20 that has reached the second end 302 from the conveying station to the exit station 102 through its own lifting action and its horizontal movement driven by the telescopic drive 60. Then it grabs the next hanging frame 20 that has reached the second end 302, thereby realizing continuous frying operation and improving the processing efficiency of fried foods that need to be constrained and shaped by frying pans.

[0023] In some embodiments, see Figure 2 and Figure 3 The top surfaces of both sides of the fryer body 30 form track surfaces 303. A lifting shaft 21 suitable for the hoist 40 to grab is horizontally inserted through the top of the lifting frame 20. Both ends of the lifting shaft 21 are equipped with rollers 211 for rolling the track surfaces 303. Setting the lifting shaft 21 as a force-taking point facilitates the grabbing operation. At the same time, the rollers 211 at both ends of the lifting shaft 21 roll the track surfaces 303, which allows the weight of the lifting frame 20 to be transferred to the track surfaces 303. This avoids the horizontal conveying mechanism 50 bearing the vertical pressure of the lifting frame 20, which helps to reduce the energy consumption of the horizontal conveying mechanism 50 and improve the stability of the movement of the lifting frame 20.

[0024] It should be noted that, as Figure 2 As shown, at least two lifting shafts 21 are spaced apart at the top of the lifting frame 20 along the extension direction of the track surface 303, and each lifting shaft 21 is provided with a roller 211 at its end. Since the rollers 211 at both ends of a single lifting shaft 21 are insufficient to provide stable support for the lifting frame 20, at least two lifting shafts 21 are provided to prevent the lifting frame 20 from swaying. Thus, the rollers 211 at both ends of each lifting shaft 21 can form a matrix support for the lifting frame 20, thereby improving the smoothness of the movement of the lifting frame 20 driven by the horizontal conveying mechanism 50.

[0025] As one specific embodiment of the above-described horizontal conveying mechanism 50, please refer to Figures 3 to 5The horizontal conveying mechanism 50 includes two closed-loop conveyor chains 51 and a drive assembly for driving the two closed-loop conveyor chains 51 to run synchronously. The closed-loop conveyor chain 51 has a conveying section 511 that slides on the track surface 303. Each link of the closed-loop conveyor chain 51 is provided with a clamping plate 512. The clamping plates 512 of adjacent links form a groove 513 suitable for the hanging shaft 21 to be inserted. The grooves 513 that are aligned with each other on the two conveying sections 511 together form a conveying station.

[0026] The lifting frame 20 is driven by a chain conveyor to travel along the track surface 303. The structure is simple and compact, and the power is stable. The track surface 303 can support the conveying section 511, thereby preventing the lifting shaft 21 from disengaging from the slot 513 and improving the conveying stability of the lifting frame 20. The slots 513 are formed by the clamping plates 512 on the adjacent chain links, thereby forming many conveying stations on the closed-loop conveying chain 51. This ensures that when the lifting frame 20 is below the hoist 40, the lifting shaft 21 can be smoothly inserted into the corresponding slot 513, improving the flexibility of placing the lifting frame 20 on the conveying station.

[0027] For example, see Figures 3 to 5 The aforementioned drive assembly includes a drive shaft 521, a driven shaft 522, and a conveyor motor 523. The drive shaft 521 is rotatably connected to one end of the fryer body 30, and both ends are fitted with drive sprockets 5211. The driven shaft 522 is rotatably connected to the other end of the fryer body 30, and both ends are fitted with driven sprockets 5221. The conveyor motor 523 is located on the fryer body 30 and its output end is connected to the drive shaft 521. Two closed-loop conveyor chains 51 are respectively located on the corresponding drive sprockets 5211 and driven sprockets 5221.

[0028] The conveyor motor 523 can specifically be a variable frequency motor. By adjusting the speed of the conveyor motor 523, the speed of the closed-loop conveyor chain 51 can be adjusted, thereby regulating the time it takes for the hanging frame 20 to travel from the first end 301 to the second end 302. This allows for continuous processing of products with different frying time requirements. The conveyor motor 523 drives the drive shaft 521 to rotate, which in turn drives the two drive sprockets 5211 to rotate synchronously. This helps improve the synchronicity of the operation of the two closed-loop conveyor chains 51, thereby improving the conveying stability of the hanging frame 20.

[0029] For some possible implementations, please refer to [link / reference]. Figures 6 to 9The hoist 40 includes a gantry frame 41, two rotary drive chains 42, a lifting drive component, and a fork arm 44. The bottom of the gantry frame 41 is horizontally slidably connected to the frame 10 and connected to the output end of the telescopic drive component 60. The two rotary drive chains 42 are respectively mounted on two columns of the gantry frame 41, and the two rotary drive chains 42 have lifting sections that move synchronously from bottom to top in the vertical direction. The lifting drive component is mounted on the gantry frame 41, and its output end is connected to the two rotary drive chains 42. One end of the fork arm 44 is slidably connected to the two columns in the vertical direction, and the other end is provided with a groove 441 suitable for the insertion of the lifting shaft 21. The middle part of the fork arm 44 is connected to the lifting section of the two rotary drive chains 42.

[0030] The purpose of using the gantry frame 41 is to avoid motion interference with the main body of the bomber 30. When the lifting drive component drives the rotary drive chain 42 to run counterclockwise, the lifting section moves from bottom to top to lift the hanging frame 20. When the lifting drive component drives the rotary drive wheel to run clockwise, the lifting section moves from top to bottom to lower the hanging frame 20.

[0031] The process of the fork arm 44 gripping and releasing the hanging frame 20 is as follows: When gripping, the lifting section moves the lower fork arm 44 from top to bottom, so that the height of the fork arm 44 is lower than that of the hanging shaft 21. Then, the telescopic drive 60 drives the gantry frame 41 to move horizontally, so that the fork arm 44 is inserted under the hanging shaft 21. When the groove 441 is aligned with the hanging shaft 21, the lifting section drives the fork arm 44 to rise, so that the hanging shaft 21 is embedded in the groove 441, thus completing the gripping action. When releasing the hanging frame 20, the lifting section moves downward until the fork arm 44 is separated from the hanging shaft 21. Then, the telescopic drive 60 drives the gantry frame 41 to move horizontally, so that the fork arm 44 is pulled out from under the hanging shaft 21. The action process is simple and stable.

[0032] For details, please refer to Figures 6 to 8 Both columns are provided with vertical guide grooves 411; the end of the fork arm 44 away from its groove 441 is connected to a first shaft 442, and the two ends of the first shaft 442 are respectively fitted with first guide wheels 4421 rolled on the vertical guide groove 411; a second shaft 443 is provided below the first shaft 442, the second shaft 443 is connected to the first shaft 442 through a connecting rod 444, and the two ends of the second shaft 443 are respectively fitted with second guide wheels 4431 rolled on the vertical guide groove 411.

[0033] By using the first guide wheel 4421 at both ends of the first shaft 442 and the second guide wheel 4431 at both ends of the second shaft 443 to roll the vertical guide groove 411, and in conjunction with the connection between the fork arm 44 and the lifting section, a three-point constraint can be formed on the movement of the fork arm 44. This can improve the load-bearing capacity of the fork arm 44, prevent the fork arm 44 from swinging after grabbing the lifting frame 20, and thus ensure the stability of the fork arm 44's vertical lifting and lowering movement driven by the lifting section.

[0034] As an optional structure for the aforementioned lifting drive component, please refer to Figure 7 The lifting drive includes a drive shaft 431, a driven shaft 432, and a lifting motor 433. The drive shaft 431 is rotatably connected to the top of the gantry frame 41, and both ends are fitted with drive sprockets 4311. The two ends of the driven shaft 432 are rotatably connected to the bottom of two columns, and both ends are fitted with driven sprockets 4321. The two driven sprockets 4321 correspond one-to-one with the two drive sprockets 4311 and are aligned vertically. The lifting motor 433 is fixed to the gantry frame 41 and its output end is connected to the drive shaft 431. Two rotary drive chains 42 are respectively located on the corresponding drive sprockets 4311 and driven sprockets 4321.

[0035] The lifting motor 433 can be a servo motor or a stepper motor with brakes. By controlling its own rotation angle, it controls the position of the lifting section driving the suspended frame 20 to rise and fall. By driving the drive shaft 431 to rotate through the lifting motor 433, the two drive sprockets 4311 drive the two rotary drive chains 42 to move synchronously, thereby improving the smoothness of the lifting movement of the suspended frame 20.

[0036] In some embodiments, the gantry 41 and the frame 10 are connected by a method such as Figure 9 The connection structure shown is as follows: The frame 10 is provided with horizontal guide grooves 103 on both sides of the frame infeed station 101 and the frame outfeed station 102. The lower ends of the two columns are provided with guide wheel sets rolled in the horizontal guide grooves 103. The guide wheel sets include a plurality of third guide wheels 412 that are spaced apart along the extension direction of the horizontal guide grooves 103.

[0037] The longitudinal beam at the bottom of the frame 10 can be made of channel steel, and the cavity of the channel steel can be used as the horizontal guide groove 103. Alternatively, the bottom of the frame 10 can be formed by bending sheet metal to create the horizontal guide groove 103. For ease of installation, the openings of the horizontal guide grooves 103 on both sides are opposite to each other. Multiple axles facing each other are set at the lower ends of the two columns and extend into the corresponding horizontal guide grooves 103. The third guide wheel 412 mounted on each axle forms a rolling fit with the horizontal guide groove 103, resulting in a simple and stable structure.

[0038] It should be noted that in this embodiment, please refer to... Figure 1 Both the infeed station 101 and the outfeed station 102 are equipped with oil receiving trays 70. By setting up oil receiving trays 70, we can prevent the spilled oil from dripping onto the ground and causing waste and pollution. On the other hand, we can provide stable support for the hanging frame 20, thereby facilitating the loading and unloading operations of the hanging frame 20.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
