Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a bean curd skin feeding device for a deep fryer. Background Technology

[0002] Crispy fried tofu skin rolls are a popular ingredient in hot pot. They are made by deep-frying tofu skin.

[0003] Most of the current crispy bean curd rolls are made using automated frying machines. However, the existing frying machines (such as the utility model patent with application number CN202322310699.9) require manual placement of bean curd sheets one by one on the conveyor. The conveyor then transports the bean curd sheets directly under the suction cup, where the suction cup holds the bean curd sheets. Finally, the cylinder operates to transport the bean curd sheets to the clamping device for frying to make crispy bean curd rolls.

[0004] The feeding device of this type of fryer requires a person to stay by the fryer at all times to place the bean curd sheets onto the conveyor so that the suction cups can pick them up, which wastes manpower and increases production costs. Summary of the Invention

[0005] To address the problem that existing fryers still require one person per machine for feeding, which wastes manpower, this utility model proposes a bean curd sheet feeding device for fryers. This device can add multiple bean curd sheets to the hopper at once, allowing one person to monitor and feed multiple machines, reducing manpower, alleviating the labor intensity of workers, and saving labor costs.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A bean curd skin feeding device for a deep fryer is provided for transporting bean curd skin to the clamping position of a clamping component. The device includes a hopper and a power mechanism. The hopper includes a bottom plate, opposing side plates on both sides of the bottom plate, and a limiting plate at one end of the bottom plate. The limiting plate is located on the side of the bottom plate closer to the clamping component. The limiting plate has a slot for removing the bean curd skin. A push plate is placed on the bottom plate, and the gap between the push plate and the limiting plate is used to place the bean curd skin. The power mechanism is located on the side of the limiting plate away from the push plate. The power mechanism transports the bean curd skin in the hopper to the clamping position of the clamping component.

[0008] Furthermore, the base plate is set at an angle or horizontally, with the end of the angled base plate closer to the limiting plate being lower than the end of the base plate furthest from the limiting plate. With the base plate angled, the push plate, under the influence of gravity, will press the bean curd skin towards one side of the limiting plate. The limiting plate prevents the bean curd skin from tilting forward, keeping it flat to facilitate removal by the suction cup.

[0009] Furthermore, a baffle is provided at the end of the horizontally positioned base plate away from the limiting plate, and a spring is provided between the baffle and the push plate. The elastic force of the compressed spring drives the push plate to push the bean curd skin to contact the inner side of the limiting plate, thereby replenishing the position where a bean curd skin is taken out.

[0010] Furthermore, it also includes a mounting plate, on which the power mechanism is mounted. The power mechanism includes a power component and a transmission component. The transmission component includes a moving rod and a rotating rod. The moving rod is connected to the output end of the power component. The rotating rod is L-shaped and includes a horizontal bar and a vertical bar. The horizontal bar rotates through the lower end of the moving rod, enabling the rotating rod to move when the moving rod slides. A connecting plate is fixed to the end of the horizontal bar near the mounting plate. The mounting plate is provided with a limiting track, in which a limiting component is slidably connected. One end of the limiting component extends out of the limiting track and its end is fixedly connected to the connecting plate, enabling the rotating rod to move and drive the limiting component to slide on the limiting track. There is a height difference between the two ends of the limiting track, enabling the sliding of the limiting component to drive the rotating rod to rotate. A fixing plate is fixed to the end of the vertical bar away from the horizontal bar. A vacuum negative pressure suction cup connected to an air pump is installed on the lower side of the fixing plate. The mounting plate is vertically set, and the moving rod is a vertical rod. A bearing is sleeved at the connection between the rotating rod and the moving rod to ensure the rotation of the rotating rod. The rotating rod and the limiting component are fixed to the connecting plate by bolts or welding.

[0011] Furthermore, the limiting track includes a first track, a third track, and a second track connected in sequence. The first track and the second track are arranged horizontally and parallel to each other, and the first track and the second track are smoothly connected through the third track.

[0012] Furthermore, the third track is tilted.

[0013] Furthermore, the point where the crossbar and the moving rod pass through is located below the first track.

[0014] Furthermore, the mounting plate is fixed to one side of the frying tank by a frame, and the hopper is fixed to one side of the frying tank by a support frame.

[0015] The beneficial effects of this utility model through the above technical solution are as follows:

[0016] 1. The hopper of this utility model can hold multiple bean curd sheets. When the hopper is tilted, the bean curd sheets are always pressed against the limiting plate at one end of the bottom plate under the gravity of the push plate, which facilitates the removal of the bean curd sheets by the subsequent power mechanism. When the hopper is set horizontally, a baffle can be set at the end of the bottom plate away from the limiting plate. A spring is set between the baffle and the push plate. The release of the spring force fixed on the baffle allows the bean curd sheets to have a tendency to move towards the limiting plate, which is conducive to the removal of the bean curd sheets. The spring force allows each bean curd sheet to move towards one side of the limiting plate after being removed, maintaining its original placement state and always adhering to the inner wall of the limiting plate. Multiple bean curd sheets can be added to the hopper at one time, allowing one person to inspect the feeding of multiple machines, reducing manual labor, alleviating the labor intensity of workers, and saving labor costs.

[0017] 2. In this utility model, the power component drives the moving rod to move. By adjusting and positioning the operating position of the power component, the angle of the suction cup is changed to align with the material picking position of the inclined or parallel material bin. Specifically, the limiting member is perpendicular to the vertical rod of the rotating rod. When the power mechanism drives the limiting member to the middle of the limiting track, the suction cup aligns with the material picking port of the horizontal material bin limiting plate to pick up the bean curd skins. When the power mechanism drives the limiting member to the end of the limiting track, the limiting member is lower, and the suction cup aligns with the material picking port of the inclined material bin to pick up the bean curd skins. When the limiting member returns to the front end of the limiting track, the suction cup, carrying the bean curd skins, aligns horizontally with the clamping member. The bean curd skins on the suction cup enter the clamping position of the clamping member, thus completing the feeding work. This cycle repeats, saving labor costs and improving production efficiency. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment provides a bean curd skin feeding device for a fryer, used to transport bean curd skin 100 to the clamping position of a clamping member 300. It includes a hopper 1 and a power mechanism. The hopper 1 includes a base plate 11, opposing side plates 12 fixedly disposed on both sides of the base plate 11, and a limiting plate 13 fixedly disposed at one end of the base plate 11. The limiting plate 13 is located on the side of the base plate 11 closest to the clamping member 300. A slot is provided on the limiting plate 13 for removing the bean curd skin 100. A push plate 14 is placed on the base plate 11, and the gap between the push plate 14 and the limiting plate 13 is used to place the bean curd skin 100. In this embodiment, the base plate 11 is inclined, with the end of the base plate 11 closest to the limiting plate 13 lower than the end of the base plate 11 furthest from the limiting plate 13. When the base plate 11 of the hopper 1 is inclined, the bean curd skin 100 is always pressed against the limiting plate 13 at one end of the base plate 11 under the weight of the push plate 14, facilitating subsequent removal. The limiting plate 13 prevents the middle part of the bean curd skin 100 from tilting forward, which would make it difficult to absorb the bean curd skin later.

[0029] The power mechanism is located on the side of the limiting plate 13 away from the push plate 14. The power mechanism transports the bean curd skin 100 in the hopper 1 to the clamping position of the clamping member 300.

[0030] For details, please refer to Figures 3-5 The feeding device also includes a mounting plate 41, and the power mechanism is mounted on the mounting plate 41. The power mechanism includes a power component 2 and a transmission component.

[0031] The transmission assembly includes a moving rod 22 and a rotating rod 23. The moving rod 22 is connected to the output end of the power assembly 2. The rotating rod 23 is L-shaped and includes a horizontal bar and a vertical bar. The horizontal bar rotates through the lower end of the moving rod 22 to realize the movement of the rotating rod 23 when the moving rod 22 slides. A bearing is provided at one end of the horizontal bar through the moving rod 22 to ensure the stability of the rotation of the rotating rod 23.

[0032] The moving rod 22 is in a vertical state and slides on one side of the mounting plate 41 under the drive of the power component 2. The power component 2 can be a cylinder, hydraulic cylinder, or a motor with a ball screw and other devices with reciprocating power function. In this embodiment, the power component 2 uses the RMH series magnetic coupling rodless cylinder from Airtac.

[0033] A connecting plate 24 is fixed to the end of the crossbar near the mounting plate 41. The crossbar and the connecting plate 24 can be fixed by bolts or welding. The mounting plate 41 is provided with a limiting rail. A limiting member 27 is slidably connected in the limiting rail. One end of the limiting member 27 extends out of the limiting rail and its end is fixedly connected to the connecting plate 24, so that the movement of the rotating rod 23 drives the limiting member 27 to slide on the limiting rail.

[0034] In this embodiment, the limiting member 27 is cylindrical and can rotate and slide in the limiting track. The limiting member 27 can be a bearing.

[0035] Specifically, the two ends of the limiting track have a height difference, which enables the sliding of the limiting component 27 to drive the rotating rod 23 to rotate; in this embodiment, the limiting track includes a first track 28, a third track 30 and a second track 29 connected in sequence. The first track 28 and the second track 29 are horizontal and parallel. The first track 28 and the second track 29 are smoothly connected through the third track 30, which is inclined.

[0036] A fixing plate 25 is fixed to the end of the vertical rod away from the horizontal rod, and a vacuum negative pressure suction cup 26 connected to an air pump is installed on the lower side of the fixing plate 25.

[0037] In this embodiment, the point where the crossbar and the moving rod 22 pass through is located below the first track 28 to increase the rotation arc of the rotating rod 23. This allows the moving rod 22, after moving a certain distance, to rotate under the cooperation of the limiting member 27 and the limiting track. The suction cup 26 on the end fixing plate 25 of the vertical rod of the rotating rod 23 adheres to the slot on the limiting plate 13 to hold the bean curd skin 100. When the rotation of the rotating rod 23 drives the limiting member 27 to the middle of the limiting track through the power component 2, the suction cup 26 is aligned with the feeding port of the horizontal hopper 1 to pick up the bean curd skin 100. When the power component 2 moves backward and drives the limiting member 27 to the end of the limiting track, the position of the limiting member 27 is lower, and the suction cup 26 is aligned with the feeding port of the inclined hopper 1 to pick up the bean curd skin 100. When the limiting component 27 returns to the front end of the limiting track, the suction cup 26, carrying the bean curd skin 100, is horizontally aligned with the clamping component 300. The bean curd skin 100 on the suction cup 26 enters the clamping position of the clamping component 300, thus completing the feeding operation. This process is repeated in a cycle.

[0038] like Figure 4As shown, in this embodiment, the limiting member 27 is located on the left side of the moving rod 22. The point where the crossbar and the moving rod 22 pass through is located below the first track 28. The position of the first track 28 is higher than the position of the second track 29. When the moving rod 22 moves, the limiting member 27 passes through the first track 28, the arc-shaped third track 30 and the second track 29 in sequence, and drives the connecting plate 24 and the rotating rod 23 fixedly connected to it to rotate counterclockwise until the suction cup 26 on the fixed plate 25 at the end of the rotating rod 23 faces the slot in the middle of the limiting plate 13. At this time, since the bean curd skin 100 is soft, the suction cup 26 can suck out the bean curd skin 100.

[0039] In another possible implementation, the difference from the above is that the limiting member 27 is located on the right side of the moving rod 22. In this case, the movement of the moving rod 22 will drive the rotating rod 23 to rotate clockwise. By adjusting and positioning the running position of the limiting member 27 driven by the power component in the limiting track according to the specific working conditions, the angle and position of the fixed plate 25 after rotation can be controlled.

[0040] In this embodiment, the limiting track comprises two identical plates arranged in parallel. In another possible embodiment, the limiting track can also be a groove with the same shape as the limiting track in this embodiment simply formed on the mounting plate 41.

[0041] The mounting plate 41 is fixed to one side of the frying tank 4 by the frame 5, and the hopper 1 is fixed to one side of the frying tank 4 by the support frame 6.

[0042] When using this equipment, firstly, multiple pieces of bean curd skin 100 are manually placed in the gap between the push plate 14 and the limiting plate 13 in the inclined hopper 1. Under the action of gravity, the push plate 14 presses the bean curd skin 100 closest to the limiting plate 13 into contact with the limiting plate 13. At this time, the power component 2 is turned on, and the moving rod 22 drives the rotating rod 23 to move. The limiting member 27 passes through the first track 28, the inclined third track 30 and the second track 29 in sequence, and drives the connecting plate 24 and the rotating rod 23 fixedly connected to it to rotate counterclockwise until the suction cup 26 on the fixed plate 25 at the end of the rotating rod 23 is aligned with the slot on the limiting plate 13. The suction cup 26 works and sucks out the bean curd skin 100. After that, the power component 2 is reset, so that the fixed plate 25 returns to its original horizontal position. At this time, the bean curd skin 100 on the suction cup 26 enters the clamping position of the clamping member 300. The work of the suction cup 26 is completed, and the next suction of bean curd skin 100 can be performed.

[0043] Example 2

[0044] like Figure 1 and Figure 2As shown, the similarities with Embodiment 1 will not be repeated. The difference lies in that the horizontally positioned base plate 11 has a baffle 42 at the end away from the limiting plate 13, and a spring 43 is provided between the baffle 42 and the push plate 14. In this case, the hopper 1 can be horizontally positioned. The elastic force of the compressed spring 43 ensures that each bean curd sheet 100 can maintain its original position after being removed and always adhere to the inner wall of the limiting plate 13. This allows for the subsequent removal of multiple bean curd sheets 100 even after they have been placed in the horizontally positioned hopper 1. It should also be understood that the elastic force of the compressed spring 43 can also be achieved by a device with telescopic function (such as a cylinder, electric cylinder, hydraulic cylinder, and push-pull rod). The hopper 1 can be tilted or horizontally positioned to adapt to different site and working conditions.

[0045] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
