[0002] In the production process of many pastries, it is often necessary to place the pastries on a baking tray for baking. After the pastries are baked, in order to ensure the cleanliness of the food and prevent the residues of the previous baking from remaining on the baking tray, thus affecting the quality of the next batch of pastries, it is necessary to wipe the baking tray. However, in the prior art, during the traditional pastry production process, the wiping of the baking tray mostly adopts manual wiping, which leads to a large amount of manual labor required for wiping the baking tray during the automated production process, with low automation degree and high labor intensity, affecting production efficiency. At the same time, the baking tray will remain at a high temperature after baking pastries, and the remaining high temperature is likely to cause burns to workers during manual wiping, causing inconvenience. Moreover, when using the prior art, since the baking tray has a relatively high residual temperature after baking, the wiping tool is easily damaged when contacting the baking tray during wiping, and the surface of the baking tray is dry after baking pastries, which is not convenient for wiping clean.

[0020] (III) Beneficial effects

[0021] One of the above technical solutions has the following advantages or beneficial effects:

[0022] 1) To address the issues in the prior art during use, in the traditional pastry production process, the wiping of baking trays was mostly done manually. This led to a large amount of manual labor required for wiping the baking trays during the automated production process, resulting in low automation and high labor intensity, which affected production efficiency. At the same time, the baking trays would retain high temperatures after baking pastries, and the residual high temperatures were likely to cause burns to workers during manual wiping, causing inconvenience. By assembling a wiping device on the conveying device of the baking tray, the wiping device is equipped with a motor lifting platform inside. The motor is connected to a wiping brush through a coupling, enabling the device to control the wiping brush to fit or move away from the baking tray through the lifting platform, and the wiping brush can be driven by the motor to rotate for wiping the baking tray. At the same time, the wiping structure of the wiping device is set within the protection range of the assembly plate, upper cover, protective plate, and side cover, which can better prevent the wiping structure from hurting people during automated wiping, and the protective cover and plates can also be conveniently opened for easy maintenance and cleaning.

[0023] 2) To address the issues in the prior art during use, since the baking trays would have relatively high residual temperatures after baking, the wiping tools were likely to be damaged when coming into contact with the baking trays during wiping. Also, the surface of the baking trays was dry after baking pastries, making it inconvenient to wipe clean. By assembling an electric control spray head on the upper cover on the side where the baking tray enters the range of the wiping device and combining it with the water supply from the water tank at the top of the wiping device, the wiping device can spray and humidify the baking tray before wiping, and then perform wiping. This can better avoid the damage of the wiping tools by the residual temperature. At the same time, compared with directly wiping the dry baking tray, wiping the humidified baking tray can better ensure a clean wipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Embodiment 1: During the use of the equipment, when cleaning and wiping, the lifting platform of the reduction motor 2i composed of the rotatable adjusting bolt 2c, the limit groove 2a, the adjusting bolt 2c, the first assembly plate 2j, the second rack 2k, the limit block 2q, the limit connecting rod 2r and the third assembly plate 2s can be lowered. The reduction motor 2i drives the wiping brush 2l to descend to a position where the baking tray can be wiped through the coupling shaft 2p. Then, the baking tray is placed on the conveyor belt 1c, and the conveyor belt 1c drives the baking tray to enter the range of the wiping device 2 through the driving of the conveyor motor 1g. At this time, the reduction motor 2i can be controlled to start through the control panel 2b to drive the wiping brush 2l to rotate, so that the wiping block 2l3 of the wiping brush 2l can wipe the baking tray. The wiping process is entirely within the protection range of the main assembly plate 2d, the upper cover 2e, the protection plate 2f and the side cover 2g of the wiping device 2, which can avoid injury to people when the wiping device 2 is wiping. In the case of realizing automatic wiping, it can better prevent the wiping structure from injuring people and avoid the inconvenience of manual wiping;

[0050] During the wiping process, the first brush plate 2l1 and the second brush plate 2l2 with a certain offset at the end can generate a certain centrifugal force, so that the wiped residues and the like move to the edge and are discharged along with the centrifugal force, so that the wiping device 2 can avoid the wiped residues staying between the two brush plates during wiping. The two brush plates adopt the method of clamping the wiping block 2l3 with a fixed assembly strip 2la and a movable assembly strip 2lb, which is convenient for quickly replacing the wiping block 2l3;

[0051] During the wiping process, the bearings 2n and the shaft sleeve 2o provided on the second assembly plate 2m of the first rod 2h enable the coupling shaft 2p to rotate more stably without affecting the lifting;

[0052] When the equipment needs to be cleaned and maintained, the rotation of the wiping brush 2l can be stopped through the control panel 2b. Then, the protective net structure can be removed by pulling out the protective frame 2f2 upward. By unlocking the lock between the upper cover 2e and the side cover 2g, the upper cover 2e and the side cover 2g can be flipped open through the hinge, which is convenient for opening and is conducive to maintenance and cleaning;

[0053] When the equipment is in use, an electric control nozzle 2t1 is assembled on the upper cover 2e on the side where the baking tray enters the wiping device 2. Combined with the water supply from the water tank 2t3 at the top of the wiping device 2, the wiping device 2 can spray and humidify the baking tray before wiping the baking tray, and then wipe it, which can better avoid damage to the wiping tool caused by the residual temperature. At the same time, the humidified baking tray can ensure better wiping effect compared with the direct wiping of the dry baking tray.

[0054] Embodiment 2: As Figure 7 shown, during the use of the equipment, without changing other structures, a water pump 4 can be installed at the water pipe 2t2 connecting the water tank 2t3 and the electric control nozzle 2t1 for spray pressurization.

[0055] Embodiment 3: As Figure 7 shown, during the use of the equipment, without changing other structures, travel switches 5 can be installed at the connections between the upper cover 2e and the side cover 2g and the protective plate 2f, and the travel switches 5 are connected in series with the reduction motor 2i, so that the equipment's protective structure will not start wiping when it is not properly closed or installed, further preventing the wiping structure from hurting people.

[0056] Embodiment 4: As Figure 7 、 8 、9 shown, during the use of the equipment, without changing other structures, a photoelectric sensor 3 can be installed on the side of the protective plate 2f away from the upper cover 2e, and the connection of the adjusting bolt 2c adjusted manually to the third assembly plate 2s is improved to the connection of the electric telescopic rod 7 to the third assembly plate 2s or the connection of the lifting motor 6 driving the adjusting bolt 2c to the third assembly plate 2s or the connection of other known lifting structures to the third assembly plate 2s, so that the equipment can be automatically controlled by program setting. The photoelectric sensor 3 senses whether the baking tray enters the range of the wiping device 2 to automatically control the reduction motor 2i to lower the lifting platform for wiping and raise it to disengage, realizing a more intelligent wiping effect.
