Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, specifically a device for feeding the inner liner of a pressure cooker. Background Technology

[0002] The inner pot of a pressure cooker is the core component of the pressure cooker and is used for cooking food. Some pressure cooker inner pots are made of metal materials such as aluminum alloy or stainless steel.

[0003] Currently, the manufacturing process of pressure cooker inner pots involves first stamping and cutting sheet metal into round plates, then placing these round plates on a stretching die, and finally stretching them into a barrel-shaped semi-finished product using a hydraulic press. When using a robotic arm for loading, the arm typically moves to the round plate placement area, picks up the round plates, places them on a positioning plate, and then uses the robotic arm to remove the barrel-shaped semi-finished product and place it on a conveyor belt for transport. Subsequently, the round plates placed on the positioning plate are picked up and placed on the stretching die. In the process of placing new round plates, the robotic arm needs to move back and forth between the round plate placement area, the stretching die, and the conveyor belt used for transporting the semi-finished product. This results in a long waiting time after the stretching die produces the semi-finished product before placing new round plates, leading to low loading efficiency in the inner pot processing. Summary of the Invention

[0004] The purpose of this invention is to provide a device for feeding the inner pot of a pressure cooker, in order to solve the problem mentioned in the background art that when the existing robotic arm feeds the material, it needs to move back and forth between the circular plate placement area, the stretching die, and the conveyor belt used for transporting semi-finished products. This back and forth movement causes excessive time loss and affects the feeding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for feeding the inner liner of a pressure cooker, comprising a base, a rotating base mounted on the base, a lifting arm mounted on the rotating base, and a telescopic part fixed to the lifting arm. A base plate is fixed to the outer end of the telescopic part, and a clamping part is mounted on one end of the base plate to clamp the semi-finished product stretched into a barrel; a reserved frame mounted on the other end of the base plate, wherein circular plates are stacked in the reserved frame, and a discharge port for discharging the circular plates is opened at the bottom of the reserved frame; a positioning port is opened on the base plate, and a positioning component is mounted on the outer side of the positioning port to position the circular plates and place them on the stretching mold; and an adjustment unit mounted on the base plate, wherein the adjustment unit is used to adjust the clamping part and drive the bottom circular plate of the reserved frame to be ejected.

[0006] Preferably, the clamping part includes two clamping plates rotatably mounted on both sides of the substrate, and a linkage rod is rotatably mounted on the inner side of the two clamping plates, and the linkage rod is connected to the adjustment unit.

[0007] Preferably, the adjustment unit includes an adjustment plate, an adjustment port is provided on the base plate, the adjustment port is connected to the bottom of the reserved frame, the adjustment plate is slidably inserted into the adjustment port, and a driving component for moving the adjustment plate is installed on the base plate. A track rod is fixed at the bottom of the base plate, and an adjustment frame is slidably sleeved on the track rod. The outer ends of the two linkage rods are rotatably connected to the outer ends of the adjustment frame. An adjustment seat is fixed at the bottom of the adjustment plate and slidably sleeved with the track rod. A buffer member adapted to the inner wall of the adjustment frame is fixed on the outside of the adjustment seat. A push spring for pushing the adjustment frame toward the clamping plate is sleeved on the outside of the track rod.

[0008] Preferably, the buffer component includes a buffer spring fixed to the outside of the adjusting seat, the buffer spring being sleeved on the outside of the track rod, and the outer end of the buffer spring being fixed with a contact ring that engages with the track rod.

[0009] Preferably, the driving component includes a drive motor fixed on the base plate by a motor frame, the base plate has a mounting port communicating with the adjustment port, and a gear is rotatably installed in the mounting port. The output end of the drive motor is fixed to the inner shaft of the gear through a coupling, and the adjustment plate has a tooth groove adapted to the gear.

[0010] Preferably, the positioning component includes a support frame fixed on the base, an electric push rod fixed on the support frame, and a push plate fixed at the output end of the electric push rod.

[0011] Preferably, the positioning element includes a positioning seat fixed to the bottom of the substrate, an inclined plate rotatably mounted inside the positioning seat, and a spring sheet fixed inside the positioning seat and fixed to the inclined plate.

[0012] Preferably, a rubber pad is installed on the inner side of the clamping plate.

[0013] Preferably, the height of the outlet is between the thickness of one and two circular plates, and the thickness of the adjusting plate is less than the thickness of one circular plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention optimizes the structure of the traditional feeding robot arm by designing a clamping part for holding the initial semi-finished product and a positioning part for placing the round plate at both ends of the substrate. This allows the substrate to be rotated sequentially by rotating the base when taking the initial semi-finished product from the stretching die and reloading it, without the need for reciprocating movement. This improves the efficiency of round plate loading and the efficiency of pressure cooker inner liner preparation.

[0017] 2. The reserved frame designed on the substrate in this invention can store a large number of circular plates at one time. With the adjustment unit, the bottom circular plate is pushed out, thereby realizing the sequential ejection of circular plates onto the stretching die. This eliminates the need for frequent movement to the circular plate placement area and improves the feeding efficiency. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 5 The device for feeding the inner liner of a pressure cooker shown in the figure includes a base 1, a rotating base 2 mounted on the base 1, a lifting arm 3 mounted on the rotating base 2, a telescopic part 4 fixed to the lifting arm 3, a base plate 5 fixed to the outer end of the telescopic part 4, a clamping part 6 mounted on one end of the base plate 5 for clamping the semi-finished product stretched into a barrel by the clamping part 6; a reserved frame 7 mounted on the other end of the base plate 5, in which round plates are stacked, and a discharge port 8 for the round plates to be discharged is opened at the bottom of the reserved frame 7. A positioning port 9 is opened on the base plate 5, and a positioning component 10 is mounted on the outside of the positioning port 9 for positioning the round plates and placing them on the stretching mold by the positioning component 10; and an adjustment unit 11 mounted on the base plate 5 for adjusting the clamping part 6 and driving the bottom round plate of the reserved frame 7 to be ejected.

[0031] In this design, the rotating base 2 can rotate on the base 1, while the lifting arm 3 can be height adjusted. The telescopic part 4 is fixed to the outer end of the lifting arm 3 and can adjust the position of the substrate 5. By designing a clamping part 6 at one end of the substrate 5, the initial blank semi-finished product stretched into a barrel-shaped structure can be clamped. With the help of the adjustment unit 11, the bottom circular plate of the reserved frame 7 is pushed into the positioning port 9. Then the rotating base 2 continues to rotate, so that the positioning port 9 at the other end of the substrate 5 moves to the top of the stretching mold. With the help of the positioning component 10, the circular plate is pushed onto the stretching mold. In the entire process of loading the circular plate and unloading the initial blank semi-finished product, only the rotating base 2 needs to rotate in one direction. There is no need to move multiple positions back and forth to load the circular plate and unload the initial blank semi-finished product. Compared with the traditional loading and unloading process of the robotic arm, the whole process takes less time and makes the inner liner loading and processing efficiency higher.

[0032] It should be noted that the rotating base 2, lifting arm 3, and telescopic part 4 in this solution are all conventional components of existing robotic arms. The rotating, lifting, and telescopic components are all existing structures, and the principles will not be elaborated in detail.

[0033] It should also be noted that a certain number of round plates can be placed in the reserved frame 7, so that when round plates are added multiple times, there is no need to frequently replenish the material.

[0034] For further details, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 and Figure 6 The clamping part 6 includes two clamping plates 12 rotatably mounted on both sides of the substrate 5. A linkage rod 13 is rotatably mounted on the inner side of the two clamping plates 12 and is connected to the adjustment unit 11 through the linkage rod 13. At the same time, in order to improve the fit with the initial semi-finished product, the end of the substrate 5 near the clamping plate 12 is designed to be an arc structure, and the arc structure of the base is made of rubber material.

[0035] Also see Figure 1 - Figure 3 and Figure 6 - Figure 9 The adjustment unit 11 includes an adjustment plate 14. An adjustment port 15 is provided on the base plate 5. The adjustment port 15 is connected to the bottom of the reserved frame 7. The adjustment plate 14 is slidably inserted into the adjustment port 15. A driving component 16 for moving the adjustment plate 14 is installed on the base plate 5. A track rod 17 is fixed at the bottom of the base plate 5. An adjustment frame 18 is slidably sleeved on the track rod 17. The outer ends of the two linkage rods 13 are rotatably connected to the outer ends of the adjustment frame 18. An adjustment seat 19 is fixed at the bottom of the adjustment plate 14 and slidably sleeved with the track rod 17. A buffer component 20 adapted to the inner wall of the adjustment frame 18 is fixed on the outside of the adjustment seat 19. A push spring 21 for pushing the adjustment frame 18 toward the clamping plate 12 is sleeved on the outside of the track rod 17.

[0036] The principle of the adjustment unit 11 driving the two clamping plates 12 to clamp the initial semi-finished product is as follows: First, the driving component 16 drives the adjustment plate 14 to move within the adjustment port 15. During the movement, the bottommost circular plate will be pushed outward and pushed outward through the discharge port 8 until it falls into the positioning port 9. During the movement of the adjustment plate 14, the buffer component 20 contacts the inner wall of one end of the adjustment frame 18 and drives the adjustment frame 18 to move. This causes one end of the adjustment frame 18 to drive the two linkage rods 13 to pull accordingly, so that the two clamping plates 12 clamp inward accordingly, thus clamping the initial semi-finished product.

[0037] It should be noted that, in order to improve clamping stability and avoid damage to the initial semi-finished product due to excessive clamping force, a rubber pad 35 is installed on the inner side of the clamping plate 12.

[0038] For further details, please refer to [link / reference]. Figure 3 The driving component 16 includes a drive motor 24 fixed on the base plate 5 by a motor frame. The base plate 5 has a mounting port 25 that communicates with the adjustment port 15. A gear 26 is rotatably mounted in the mounting port 25. The output end of the drive motor 24 is fixed to the inner shaft of the gear 26 by a coupling. The adjustment plate 14 has a tooth groove 27 that matches the gear 26. The drive motor 24 drives the gear 26 to rotate, thereby causing the adjustment plate 14, which meshes with the tooth groove 27, to move accordingly. The forward and reverse rotation of the gear 26 drives the adjustment plate 14 to move forward and backward.

[0039] For further details, please refer to [link / reference]. Figure 2 , Figure 4 and Figure 6 The positioning component 10 includes a support frame 28 fixed on the base, an electric push rod 29 fixed on the support frame 28, a push plate 30 fixed at the output end of the electric push rod 29, the outer diameter of the positioning port 9 is larger than the outer diameter of the circular plate, and a number of positioning elements 31 are installed at the bottom of the positioning port 9, and the multiple positioning elements 31 support and position the inner circular plate of the positioning port 9.

[0040] The positioning component 31 includes a positioning seat 32 fixed to the bottom of the base plate 5, an inclined plate 33 rotatably mounted inside the positioning seat 32, and a spring sheet 34 fixed inside the positioning seat 32 and fixed to the inclined plate 33.

[0041] The positioning component 10 fulfills the principle of positioning the circular plate and placing it above the stretching die:

[0042] First, the bottommost circular plate is pushed out of the outlet 8 by the adjusting plate 14 and moved into the positioning port 9. The circular plate is held and positioned by multiple positioning parts 31. Then, the electric push rod 29 drives the push plate 30 to move down, pressing down the circular plate held by multiple positioning parts 31 until it is detached from the positioning parts 31 and falls above the stretching die, thus realizing the positioning and feeding operation of the circular plate.

[0043] It should be noted that when the circular plate falls onto the multiple inclined plates 33 at the positioning port 9, the multiple inclined plates 33 support the circular plate against each other, preventing the circular plate from falling directly. At the same time, the push plate 30 presses down, correcting and positioning the circular plate during this process. Under the action of external pressure, the multiple inclined plates 33 are pushed open, so that the circular plate finally falls above the stretching die.

[0044] This solution implements a high-efficiency pressure cooker inner pot loading process, including the following steps:

[0045] The first step is to observe the number of circular plates inside the reserved frame 7. If the number is insufficient, add more circular plates to the reserved frame 7.

[0046] The second step involves rotating the base 2 to drive the corresponding rotation of the lifting arm 3, the telescopic part 4, and the base plate 5 until the clamping part 6 moves to the stretching die.

[0047] The third step involves moving the adjustment unit 11 to control the clamping plate 12 to clamp the stretched semi-finished product on the stretching die, while the adjustment plate 14 moves to push the bottommost round plate out into the positioning port 9.

[0048] Fourth step, the rotating base 2 continues to move, moving the clamped pre-finished blank above the conveyor belt, and moving the positioning port 9 above the stretching die;

[0049] The fifth step involves moving the adjustment unit 11 in the reverse direction to reset the adjustment plate 14, while simultaneously opening the clamping plate 12 from the clamping state. The lifting arm 3 then moves the substrate 5 upward to complete the unloading of the initial semi-finished product onto the conveyor belt.

[0050] The sixth step involves lowering and resetting the lifting arm 3, and then lowering the circular plate to the top of the stretching die via the positioning component 10 for loading.

[0051] Step 7: Continue to rotate the rotating base 2 to move the clamping part 6 to the outside of the stretching die again, and repeat steps 1 to 7 to achieve automated feeding operation.

[0052] In this scheme, the substrate 5 is moved by rotating the base 2. During the rotation, the initial semi-finished product of the stretching die is unloaded and the circular plate is loaded onto the stretching die as the stretching die continues to rotate. The entire motion trajectory is a rotation in one direction, without the need for reciprocating movement, which reduces the time loss caused by reciprocating movement and improves the loading and unloading efficiency during the processing of the pressure cooker inner liner.

[0053] In this design, since the substrate 5 adopts a rotational trajectory in the same direction, multiple sets of stretching die equipment and conveyor belt mechanisms can be designed, preferably two sets, such as... Figure 10As shown, the substrate 5 rotates between two sets of stretching die equipment and the conveyor belt mechanism, which can continuously remove the stretched semi-finished products from the two sets of stretching die equipment and feed the round plate, thereby further improving the processing efficiency of the pressure cooker inner liner.

[0054] Example 2: Please refer to Figure 6 , Figure 8 and Figure 9 This embodiment further explains the first embodiment, the difference being that it discloses a specific embodiment of the buffer 20, which can drive the movement of the adjustment frame 18.

[0055] Specifically, the buffer component 20 includes a buffer spring 22 fixed to the outside of the adjusting seat 19, the buffer spring 22 is sleeved on the outside of the track rod 17, and the outer end of the buffer spring 22 is fixed with a contact ring 23 that is sleeved with the track rod 17.

[0056] In this design, when the adjusting seat 19 moves with the adjusting plate 14, it will drive the buffer spring 22 and the contact ring 23 to move on the track rod 17. When the contact ring 23 abuts against the inner wall of the adjusting frame 18, it can drive the adjusting frame 18 to move accordingly, and drive the clamping plate 12 to start rotating to clamp the pre-formed semi-finished product. In order to improve the clamping tightness of the clamping plate 12 and avoid the clamping plate 12 rotating too much and causing damage to the pre-formed semi-finished product, the buffer spring 22 is compressed to generate elastic force, so that the clamping plate 12 has a certain buffer range when clamping, which maintains the clamping tightness and avoids the large rotation angle from causing damage to the pre-formed semi-finished product.

[0057] Example 3: Please refer to Figure 4 This embodiment further illustrates other embodiments, the difference being that the thickness relationship between the outlet 8, the circular plate and the adjusting plate 14 is limited, making the pushing out of the bottom circular plate more stable.

[0058] Specifically, the height of the outlet 8 is between the thickness of one and two circular plates. The thickness of the adjusting plate 14 is less than the thickness of one circular plate. The height of the outlet 8 is optimally set to 1.5 times the thickness of the circular plate, so that the bottommost circular plate can be pushed out smoothly each time the circular plate is pushed to move, while the second to last layer cannot move. At the same time, the thickness of the adjusting plate 14 is optimally set to half the thickness of the circular plate, so that the bottommost circular plate can be stably pushed out each time during the movement.
