Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a limiting structure for stabilizing a baking pan. Background Technology

[0002] In vertical baking ovens, the feeding and discharging of baking trays are mostly accomplished using conveyor belts. Specifically, during feeding, the baking tray is placed at the feeding end of the conveyor belt, which moves horizontally to the lifting station. Then, it is conveyed upward by the lifting mechanism inside the vertical baking oven. After the baking tray moves to the highest position, it is pushed to the lowering mechanism by the switching mechanism for downward conveying. Finally, the baking tray is conveyed downward onto the conveyor belt, which then horizontally exits the vertical baking oven.

[0003] The baking tray has a certain horizontal inertia when it enters the lifting mechanism from the conveyor belt, which makes it easy for it to enter the lowering mechanism from the lifting mechanism, affecting the smooth passage of the items through the oven for baking. Therefore, further improvement is needed. Utility Model Content

[0004] To address the aforementioned problems, this application provides a limiting structure for stabilizing a baking pan.

[0005] The limiting structure for stabilizing a baking pan provided in this application adopts the following technical solution:

[0006] A limiting structure for stabilizing a baking tray includes an oven, a conveyor frame, and a baking tray. The oven has inlet and outlet ports on its opposite side walls for the conveyor frame to pass through. The conveyor frame is equipped with a conveyor belt that horizontally transports the baking tray. The oven is equipped with a lifting mechanism and a lowering mechanism for lifting and lowering the baking tray, respectively. The conveyor frame is equipped with a first limiting component for blocking the baking tray. The first limiting component is located between the lifting mechanism and the lowering mechanism. The first limiting component includes a first limiting plate, which is disposed on the conveyor frame and located above the conveyor belt.

[0007] By adopting the above technical solution, inlet and outlet ports are opened on both sides of the oven to facilitate the installation of the conveyor frame. The baking trays on the conveyor belt can enter and exit the oven through the inlet and outlet ports. The lifting mechanism and the lowering mechanism can respectively realize the lifting and lowering of the baking trays. The first limiting plate located between the lifting mechanism and the lowering mechanism can block the baking trays and prevent them from directly entering the lowering mechanism from the lifting mechanism due to the horizontal running inertia, effectively ensuring that the baking trays are stably transported into the lifting station.

[0008] Preferably, the first limiting component further includes a first limiting seat and a connecting arm, the first limiting seat being fixed to the conveyor frame; the connecting arm being disposed on the first limiting seat, and the first limiting plate being fixedly connected to the connecting arm.

[0009] By adopting the above technical solution, the first limiting seat is fixed to the conveyor frame, and the first limiting plate is connected to the first limiting seat by the connecting arm. This can achieve a stable setting of the first limiting plate on the conveyor frame, enhance the stability of the first limiting plate, and thus more effectively block the baking tray, ensuring that the baking tray is stably conveyed into the lifting station.

[0010] Preferably, the first limiting plate is vertically slidably connected to the first limiting seat, and the first limiting seat is provided with a second driving component for driving the connecting arm to slide vertically.

[0011] By adopting the above technical solution, the first limiting plate can slide vertically to the first limiting seat, and the connecting arm is driven to slide vertically by the second driving component. This allows for flexible adjustment of the vertical position of the first limiting plate, better adapting to the conveying needs of baking trays of different heights, and improving the stability and applicability of the limiting mechanism.

[0012] Preferably, an elastic gasket is fixedly connected to the surface of the first limiting plate near the lifting mechanism, and the elastic gasket is used to abut against the front outer wall of the baking pan.

[0013] By adopting the above technical solution, an elastic pad is set on the plate surface of the first limiting plate near the lifting mechanism. When the outer wall of the front side of the baking pan abuts against the elastic pad, it can play a buffering role and reduce the impact force when the baking pan collides with the first limiting plate.

[0014] Preferably, the conveyor frame is provided with a second limiting component for correcting and limiting the baking tray. The second limiting component is located outside the oven and includes a mounting frame, a second limiting seat, and a second limiting plate. The mounting frame is fixed to the conveyor frame, and the second limiting seat is located below the conveyor belt and is fixedly connected to the mounting frame. There are two second limiting plates, which are located on both sides of the conveyor belt. The second limiting plates slide along the width direction of the conveyor belt and are connected to the second limiting seat. The second limiting seat is provided with a fourth driving component for driving the second limiting plate to slide.

[0015] By adopting the above technical solution, the second limiting component includes a mounting frame, a second limiting seat, and a second limiting plate. The mounting frame is fixed to the conveyor frame, so that the second limiting component is stably set on the conveyor frame. The two second limiting plates are located on both sides of the conveyor belt and can slide along the width direction of the conveyor belt to be connected to the second limiting seat. The sliding is driven by the fourth driving component, and the distance between the two second limiting plates can be flexibly adjusted according to the width of the baking tray, which improves the applicability.

[0016] Preferably, the upper end face of the second limiting seat is provided with a sliding groove, and the second limiting plate is fixedly connected with a sliding block that is slidably connected to the sliding groove.

[0017] By adopting the above technical solution, the second limiting plate is slidably connected to the sliding groove opened on the upper end surface of the second limiting seat through the sliding block, so that the second limiting plate can slide smoothly along the width direction of the conveyor belt.

[0018] Preferably, the fourth drive assembly includes a lead screw and a second motor. The lead screw is rotatably connected to the inner wall of the sliding groove, and the axial direction of the lead screw is parallel to the length direction of the sliding groove. The lead screw has a first threaded section and a second threaded section, and the first threaded section and the second threaded section are opposite in direction. The first threaded section and the second threaded section are respectively threaded through two sliding blocks. The second motor is fixed to the outer wall of the second limiting seat, and the output shaft of the second motor is coaxially fixedly connected to the end of the lead screw.

[0019] By adopting the above technical solution, the lead screw is rotatably connected to the inner wall of the sliding groove and its axial direction is parallel to the length direction of the sliding groove. The first and second threaded sections with opposite directions are respectively inserted into the two sliding blocks. The output shaft of the second motor is connected to the end of the lead screw, which can drive the lead screw to rotate. The opposite threaded sections drive the two sliding blocks to move towards or away from each other, thereby causing the two second limiting plates to slide synchronously on both sides of the conveyor belt along the width direction, so as to achieve precise correction and limiting of the baking tray.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. The oven has inlet and outlet ports on both sides to facilitate the installation of the conveyor frame. Baking trays on the conveyor belt can enter and exit the oven through the inlet and outlet ports. The lifting mechanism and the lowering mechanism can lift and lower the baking trays respectively. The first limit plate located between the lifting mechanism and the lowering mechanism can block the baking trays and prevent them from directly entering the lowering mechanism from the lifting mechanism due to horizontal running inertia, effectively ensuring that the baking trays are stably transported into the lifting station.

[0022] 2. The second limiting component includes a mounting frame, a second limiting seat, and a second limiting plate. The mounting frame is fixed to the conveyor frame, so that the second limiting component is stably set on the conveyor frame. The two second limiting plates are located on both sides of the conveyor belt and can slide along the width of the conveyor belt to be connected to the second limiting seat. The sliding is driven by the fourth driving component. The distance between the two second limiting plates can be flexibly adjusted according to the width of the baking tray, which improves the applicability. Attached Figure Description

[0038] Reference Figure 2 , Figure 7The oven 1 is equipped with a shifting mechanism 7 that moves the baking tray 3 from the lifting mechanism 4 to the lowering mechanism. The shifting mechanism 7 is located above the lifting mechanism 4 and the lowering mechanism. The shifting mechanism 7 includes a first shifting cylinder 71, a mounting block 72, a second shifting cylinder 73, and a gripper 74. There are two first shifting cylinders 71, which are spaced apart along the width direction of the conveyor belt 21. The first shifting cylinders 71 are slidably connected to the inner top wall of the oven 1 along the length direction of the conveyor belt 21, and the piston rods of the first shifting cylinders 71 are set downward. The number of mounting blocks 72 corresponds to the number of first shifting cylinders 71, and the mounting blocks 72 are fixed to the lower end face of the piston rod of the first shifting cylinder 71. Each mounting block 72 is equipped with two second shifting cylinders 73, and the piston rods of the two second shifting cylinders 73 face opposite directions.

[0040] The implementation principle of the limiting structure for stabilizing a baking tray in this application embodiment is as follows: During the process of conveying the baking tray 3 into the oven 1 by the conveyor belt 21, it abuts against the outer wall of the limiting protrusion 31 of the baking tray 3, thereby realizing the correction and limiting of the baking tray 3. After the baking tray 3 enters the oven 1, the elastic pad 55 of the first limiting plate 54 abuts against the baking tray 3, blocking the baking tray 3, so that the baking tray 3 is accurately located at the lifting position. The support bar 45 located on the inner side of the lifting mechanism 4 drives the baking tray 3 to move upward by abutting against the lower end face of the limiting protrusion 31. When the baking tray 3 is lifted to the highest position, the support bar 45 stops moving, the piston rod of the first shifting cylinder 71 extends to push the mounting block 72 and the second shifting cylinder 73 to move downward as a whole, and the piston rod of the second shifting cylinder 73 retracts, so that the two grippers 74 move towards each other. The sliding motion causes the insertion block 742 on the gripper 74 to be inserted into the insertion slot 32. Then, the piston rod of the first shifting cylinder 71 retracts, causing the baking tray 3 to move upward as a whole, so that the baking tray 3 is disengaged from the support bar 45 of the lifting mechanism 4. Then, the third drive assembly 75 drives the first shifting cylinder 71 to move above the lowering mechanism. The piston rod of the first shifting cylinder 71 extends, causing the baking tray 3 to move downward as a whole, so that the limiting protrusion 31 of the baking tray 3 abuts against the support bar 45 on the inner side of the lowering mechanism. Subsequently, the piston rod of the second shifting cylinder 73 extends, causing the insertion block 742 of the gripper 74 to disengage from the insertion slot 32. The support bar 45 of the lowering mechanism realizes the lowering and conveying of the baking tray 3 during the transmission process. The baking tray 3 returns to the conveyor belt 21 through the lowering mechanism and is finally transported out of the oven 1 by the conveyor belt 21.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
