[0035] In the food baking industry, repetitive baking work is generally completed with the help of baking carts and baking trays. However, currently, when the baking trays are transported, they need to be completed manually while wearing heat-resistant gloves. On the one hand, the temperature of the baking trays is relatively high, which poses a certain threat to personnel safety. In addition, the efficiency of manual operation is relatively low, and it is difficult to ensure food safety.

[0036] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0037] Figure 1 It is a structural schematic diagram of a baking conveying device shown in an embodiment of the utility model;

[0038] Figure 2 It is a top view of a baking conveying device shown in an embodiment of the utility model.

[0039] See also Figure 1 to Figure 2 , a baking conveying device provided by an embodiment of the utility model comprises a frame 1 having a chamber for accommodating a baking cart;

[0040] The conveying mechanism 2 comprises a first conveyor 21, a second conveyor 22 and a third conveyor 23, wherein the second conveyor 22 is rotatably connected to the first conveyor 21, a first end of the third conveyor 23 is rotatably connected to the second conveyor 22, a second end of the third conveyor 23 extends into the chamber, and a conveying direction of the third conveyor 23 is parallel to a horizontal plane;

[0041] The vertical lifting mechanism 3 includes a transmission assembly 31 arranged on both sides of the frame 1 and a driving assembly 32 driving the transmission assembly 31 to reciprocate along the height direction of the frame 1. The driving assembly 32 is arranged on the frame 1, and the transmission assembly 31 is connected to the third conveyor 23.

[0042] The embodiment of the present application takes a baking tray used for baking as an example to explain the embodiment of the present application in detail.

[0043] In an embodiment of the present application, the baking conveying device includes a frame 1, a conveying mechanism 2 and a vertical lifting mechanism 3, wherein the second conveyor 22 in the conveying mechanism 2 is rotatably connected to the first conveyor 21 and the third conveyor 23 respectively, and the driving component 32 drives the transmission component 31 to move along the height direction of the chamber, thereby driving the third conveyor 23 to move in the chamber. When the third conveyor 23 moves, the second conveyor 22 can rotate accordingly, thereby ensuring that the conveying mechanism 2 can be smoothly transported through the conveying mechanism 2 after the baking tray is taken by the third conveyor 23. After the baking tray and the baking cart with food have finished high-temperature baking, the operator, wearing heat-resistant gloves, pushes the baking cart into the chamber of the frame 1. At this time, the first conveyor 21 is located at the bottom of the baking cart (i.e., the bottom of the baking tray at the bottom layer). At this time, the device can be started, the conveying mechanism 2 starts conveying, and the vertical lifting mechanism 3, under the control of the control system, the driving component 32 drives the transmission component 31 to move upward, thereby driving the third conveyor 23 to move upward. After the third conveyor 23 contacts the baking tray, the baking tray can be removed from the baking cart and transported to the next process through the third conveyor 23, the second conveyor 22 and the first conveyor 21. When the previous baking tray is separated from the baking cart, under the combined operation of the driving component 32 and the transmission component 31, the third conveyor 23 continues to move upward, and after contacting the bottom of the baking tray, the circular conveying function is realized.

[0044] The third conveyor 23 provided in the conveying device for baking can keep the conveying direction parallel to the horizontal plane under the drive of the vertical lifting mechanism 3, so that when the third conveyor 23 contacts the container of the baking cart, it has the largest contact surface, ensuring that the container can be quickly transferred when it contacts the third conveyor 23. The second conveyor 22 is rotatably connected to the first conveyor 21 and the third conveyor 23 respectively. When the third conveyor 23 moves up and down in the vertical direction, the second conveyor 22 plays a buffering role to prevent the container from sliding rapidly due to excessive drop, resulting in damage to the food in the container.

[0045] In this embodiment, the movement stroke of the driving component 32 driving the transmission component 31 can be set according to the distance between two adjacent baking trays in the baking cart, which is not the only limitation here.

[0046] In a possible implementation, in order to prevent the baking cart from moving during operation and the container from being unable to align with the third conveyor 23 or the bottom of the container not completely falling into the range of the third conveyor 23, the embodiment of the present application sets a limiting mechanism 4 to ensure the stability of the baking cart in the chamber. The above-mentioned baking conveying device also includes a limiting mechanism 4, including limiting components 41 located on both sides of the chamber and a power component 42 driving the limiting component 41 to rotate around its own axis, and the limiting component 41 is used to limit the baking cart. Specifically, when the baking cart enters the chamber, the operator can drive the limiting component 41 to rotate around its own axis through the power component 42, so that the limiting component 41 can contact and resist the baking cart, thereby ensuring the stability of the baking cart in the chamber.

[0047] In one possible implementation, see Figure 5 , and combined with Figure 1 The limiting assembly 41 of the baking conveying device includes a transmission tooth 411, a bearing 412, a vertical rod 413 and a baffle 414. The bearing 412 is arranged on the frame 1, the vertical rod 413 is installed in the bearing 412, the end of the vertical rod 413 is connected to the transmission tooth 411, the baffle 414 is arranged on the vertical rod 413 and extends in the radial direction of the vertical rod 413, and the transmission tooth 411 is connected to the power assembly 42. Specifically, when the power assembly 42 drives the vertical rod 413 to rotate through the transmission tooth 411, the radially arranged baffle 414 can rotate accordingly, thereby achieving contact and abutment with the baking cart.

[0048] In one possible implementation, see Figure 3 and Figure 4The power assembly 42 of the baking conveying device includes a push rod motor 421 and a transmission seat 422. The transmission seat 422 is connected to the piston rod of the push rod motor 421 and is slidably connected to the frame 1 through a second slide rail mechanism. The push rod motor 421 drives the transmission seat 422 to move along the axial direction of the piston rod. Transmission teeth 411 are provided at both ends of the transmission seat 422, and the transmission teeth 411 are meshed with the transmission teeth 411. Specifically, the push rod motor 421 in the embodiment of the present application can preferably be arranged on the top of the frame 1, and a transmission seat 422 is arranged on the top of the frame 1. The piston rod of the push rod motor 421 pushes the transmission seat 422 to move, thereby driving the transmission gear 411 to rotate, and finally realizing the rotation of the baffle 414. By setting the push rod motor 421 and setting transmission teeth 411 at both ends of the transmission seat 422, and connecting them with the limit assemblies 41 on both sides of the chamber, it can be ensured that the baffles 414 located on both sides of the chamber have the same rotation amplitude, and the overall structural stability of the limit mechanism 4 can be ensured.

[0049] In one possible implementation, see Figure 3 and Figure 4 The driving assembly 32 of the baking conveying device includes a motor 321, a first rotating shaft 322 and a first reversing gear 323. The motor 321 is connected to the first rotating shaft 322, and both ends of the first rotating shaft 322 are connected to the first reversing gear 323. The motor 321 is arranged on the top of the frame 1.

[0050] The transmission assembly 31 includes a second rotating shaft 311 respectively arranged on both sides of the inside of the frame 1, a second reversing gear 312 adapted to the first reversing gear 323, a transmission gear wheel 313, a transmission belt 314, a connecting plate 316 and a fixed seat 315, the second rotating shaft 311 is connected to the second reversing gear 312, the second rotating shaft 311 can be rotatably arranged on the frame 1, the transmission gear wheel 313 is respectively installed on the second rotating shaft 311 and the fixed seat 315, the transmission belt 314 is installed on the transmission gear wheel 313, the fixed seat 315 is installed at the bottom of the frame 1, and the transmission belt 314 is connected to the third conveyor 23 through the connecting plate 316.

[0051] Specifically, the second rotating shaft 311 located at the top of the frame 1 can be installed on the frame 1 through the bearing seat 320.

[0052] In a preferred embodiment, the motor 321 can be a stepper motor.

[0053] A stepper motor is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement outputted is proportional to the number of pulses inputted, and the rotation speed is proportional to the pulse frequency. Therefore, the stepper motor can accurately control the up and down movement distance of the transmission belt 314, and thus can accurately position the travel of baking carts of different sizes and specifications, ensuring that the stepper motor can drive the third conveyor 23 to pick up a baking tray once when it runs once.

[0054] In a possible embodiment, the transmission assembly 31 of the baking conveying device further includes a slide rail mechanism 317 and a first plate body 318 and a second plate body 319 arranged in a stacked manner, wherein teeth cooperating with the transmission belt 314 are provided on the end surface of the first plate body 318 opposite to the second plate body 319, the first plate body 318 is connected to the second plate body 319 by bolts, the second plate body 319 is connected to the connecting plate 316, the connecting plate 316 is connected to the third conveyor 23, the fixed end of the slide rail mechanism 317 is connected to the frame 1, and the movable end of the slide rail mechanism 317 is connected to the connecting plate 316. By providing the slide rail mechanism 317, the connection strength between the connecting plate 316 and the third conveyor 23 can be improved, and specifically, the slide rail mechanism 317 can be connected to the connecting plate 316 by slide rails fixed on both sides of the frame 1 and sliders connected to the slide rails.

[0055] In a possible implementation, the vertical lifting mechanism 3 of the baking conveying device further includes a plurality of limit rods 33 vertically arranged on the frame 1, the ends of the plurality of limit rods 33 correspond to the connecting plate 316, and the limit rods 33 are used to limit the maximum travel of the third conveyor 23 on the chamber. The use of the limit rods 33 to limit the third conveyor 23 can further ensure the safe operation of the third conveyor 23 and prevent the third conveyor 23 from moving beyond a preset range under the transmission of the motor 321. When the third conveyor 23 hits the limit rod 33, a corresponding reminder module can also be provided to remind the operator to shut down or replace the baking cart.

[0056] In one possible implementation, see Figure 3 The first conveyor 21 of the baking conveying device includes a first bracket 211, a transmission motor 212 and a first conveyor belt 213. The transmission motor 212 is arranged on the first bracket 211, and the first conveyor belt 213 is connected to the transmission motor 212;

[0057] The second conveyor 22 includes a second bracket 221 and a second conveyor belt 222 . The second bracket 221 is rotatably connected to the first bracket 211 and the third conveyor 23 , respectively. The second conveyor belt 222 is connected to the rotating shaft of the first conveyor belt 213 .

[0058] In a possible embodiment, the third conveyor 23 of the above-mentioned baking conveying device includes a third bracket 231 and a third conveyor belt 232, the first end of the third bracket 231 is rotatably connected to the second bracket 221, the second end of the third bracket 231 is located in the chamber, the third conveyor belt 232 is connected to the rotating shaft of the second conveyor belt 222, and the third bracket 231 is connected to the transmission assembly 31.

[0059] In a possible implementation manner, the third conveyor 23 of the baking conveying device further includes a weight sensor 233 , and the weight sensor 233 is used to detect whether the container on the baking cart is placed on the third conveyor 23 .

[0060] Specifically, when the user starts the device, the device sends a communication signal to the weight sensor 233. After receiving the communication signal, the weight sensor 233 replies a response signal to the device. If the device receives the signal sent by the weight sensor 233, it analyzes and determines whether there is a baking tray on the third conveyor 23 according to the response signal. If there is a baking tray on the current third conveyor 23, the device maintains the current action (i.e., does not drive the vertical lifting mechanism 3 to move). If there is no baking tray on the current third conveyor 23, the device drives the vertical lifting mechanism 3 to move upward to achieve the next round of baking tray receiving operation.

[0061] It should be noted that there are multiple ways to obtain whether the baking tray is on the third conveyor 23. In addition to the gravity sensor described above, a photoelectric sensor and an infrared sensor can also be used to obtain whether there is a baking tray on the third conveyor 23. Therefore, the weight sensor 233 in this embodiment is only one of the implementations designed to adapt to the weight detection of this embodiment, so the weight sensor 233 should not be understood as the only implementation form of the embodiment of the present application.

[0062] Compared with the prior art, the utility model provides a baking conveying device, the combined operation of the third conveyor 23 and the vertical lifting mechanism 3, which can smoothly take the baking tray from the baking cart and realize stable transmission through the second conveyor 22. It has a high degree of automation, can improve the production efficiency of the production line, and can ensure the safety of food.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
