Description

Technical Field

[0001] The utility model relates to the technical field of food machinery, in particular to a water-cooled conveying pancake baking device. Background Art

[0002] Barbecue pancakes are generally baked in a baking oven. Manual production of pancakes has low efficiency, not only with high labor intensity, but also the hygiene problem cannot be guaranteed, unable to meet the market demand. Thus, various pancake production lines have emerged, greatly improving the production efficiency.

[0003] At present, the existing pancake baking devices generally pre-fabricate pancake embryos and use a conveying device to reciprocally and circularly convey the pancake embryos into the baking oven for baking, and then convey the baked small pancakes out. Because the conveying device passes through the high-temperature area of the baking oven for a long time, relying solely on heat exchange with the outside air cannot achieve the purpose of complete heat dissipation, and it is easy to shorten its service life. In addition, the production of pancake embryos and the baking of pancake embryos are carried out step by step, which is also not conducive to the large-scale production of pancakes and the production efficiency is not high. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a water-cooled conveying pancake baking device, which can realize the integrated processing of pancake embryo cutting, leftover material recycling, and pancake embryo baking, and uses a water-cooled conveyor belt to complete the conveyance of pancake embryos, effectively solving the problem that the conveyor belt's life is affected due to the continuous temperature rise when it circulates through the baking oven during production.

[0005] The utility model is realized by the following technical solutions:

[0006] Provide a water-cooled conveying pancake baking device, including a frame. An open water tank is arranged below the head end of the frame, and a tensioning roller is rotatably installed in the open water tank. A towing roller is rotatably installed above the head end of the frame, and a pulling roller is rotatably installed above the tail end of the frame. A conveyor belt is installed between the tensioning roller, the towing roller, and the pulling roller on the frame. On the frame above the conveyor belt, a knife roller mechanism for rolling and cutting pancake embryos, a leftover material recycling mechanism for recycling dough sheets, and a baking oven for baking the pancake embryos until they are cooked are sequentially installed along the conveying direction.

[0007] Furthermore, a conveying driving roller for driving the conveyor belt to rotate is rotatably installed inside the frame. A driving roller sprocket is installed on one end of the roller shaft of the conveying driving roller. A motor is installed inside the frame below the conveying driving roller. A motor sprocket is installed on the driving shaft of the motor. The motor sprocket and the driving roller sprocket are connected by a chain drive.

[0008] The conveyor belt is supported by the conveying driving roller in cooperation with the tensioning roller and the towing roller to complete the operation. The conveying driving roller obtains power through the sprocket and the chain in cooperation with the motor, and then drives the entire conveyor belt to reciprocally move circularly.

[0009] Furthermore, the oven is installed above the conveyor belt by means of a mounting frame, and the distance between the oven and the conveyor belt is less than or equal to the thickness of the cake embryo.

[0010] The oven is installed above the conveyor belt through a mounting frame. By limiting the distance between the oven and the conveyor belt, it can be ensured that the cake embryos on the conveyor belt can adhere to the oven through the extrusion friction between the oven and the conveyor belt when passing through the oven, thereby completing the baking of the cake embryos.

[0011] Furthermore, the mounting frame is also connected with a material receiving net chain between the oven and the residual material recovery mechanism.

[0012] The mounting frame is provided with a material receiving net chain between the oven and the residual material recovery mechanism, and the baked cakes matured in the oven will fall onto the material receiving net chain as the oven rotates, so as to be easily collected.

[0013] Furthermore, a support platform for supporting the conveyor belts is provided between the upper and lower conveyor belts directly below the oven in the frame.

[0014] A support platform is provided inside the frame to support the upper conveyor belt, so that when the oven rotates to the point where the conveyor belt takes away the cake embryo, the upper conveyor belt can be supported to prevent the conveyor belt from being squeezed and deformed, thus affecting its service life.

[0015] Furthermore, the knife roller mechanism includes a knife roller frame mounted above the conveyor belt, on which a knife roller that is adaptively contacted with the conveyor belt is rotatably mounted via a spring support structure, and a knife for cutting cake embryos from the dough is arranged on the roller surface of the knife roller.

[0016] The knife roller mechanism contacts the conveyor belt and uses the rotational friction of the conveyor belt to drive it to rotate. After the dough passes between the knife roller and the conveyor belt, it will be cut into the shape of a cake embryo by the knife on the rotating knife roller as it is transported along the conveying direction, thus completing the cutting and transportation of the cake embryo.

[0017] Furthermore, the residual material recovery mechanism includes a residual material conveying bracket mounted above the conveyor belt and connected to the frame, the upper part of the residual material conveying bracket is rotatably connected to a winding roller spanning the conveyor belt, one end of the winding roller is connected to a winding motor, a residual material conveyor belt located above the conveyor belt and perpendicular to the conveyor belt is installed between the residual material conveying bracket and the frame, the conveying roller at one end of the residual material conveying belt is rotatably mounted on the residual material conveying bracket, and the end of the conveying roller is transmission-connected to the residual material conveying motor through a sprocket and a chain.

[0018] The residual material recovery mechanism can drive the rolling roller to rotate through the rolling motor to recycle the dough cut by the knife roller mechanism and send it to the residual material conveyor belt. The residual material conveying motor drives the conveying roller to rotate and then drives the leading conveyor belt to rotate to transport the returned dough along the direction perpendicular to the conveyor belt, and it can be sent to the dough pressing machine for secondary processing.

[0019] Furthermore, an inclined water receiving tank is installed inside the frame below the conveyor belt, and the lower end of the water receiving tank is lapped on the opening of the open-top water tank.

[0020] A water receiving tank is arranged inside the frame below the conveyor belt to collect the water droplets dripping from the conveyor belt, prevent them from dripping onto the ground or the frame, ensure the hygiene of the production area and prevent rusting during long-term use.

[0021] Furthermore, the open-top water tank is also connected to a cooling water inlet pipe, an electromagnetic valve is installed on the cooling water inlet pipe, a temperature sensor alarm is installed on the frame, the temperature measuring probe of the temperature sensor alarm is arranged inside the open-top water tank, and the controller of the temperature sensor alarm is electrically connected to the electromagnetic valve.

[0022] The temperature measuring probe of the temperature sensor alarm is used to detect the water temperature inside the open-top water tank. When the temperature exceeds the threshold set by the temperature measuring probe, the temperature sensor alarm will be triggered to emit a sound and light alarm to remind the staff to deal with it in time. At the same time, the controller is used to control the electromagnetic valve on the cooling water pipe to open, so that the cooling water is introduced into the open-top water tank for heat exchange and cooling to ensure the continuous water cooling effect on the conveyor belt.

[0023] The beneficial effects of the present utility model are as follows:

[0024] The present utility model provides a water-cooled conveyor baking equipment, which can realize the integrated processing of cake embryo cutting, waste material recovery and cake embryo baking, save labor, improve production efficiency, facilitate large-scale production, and ensure hygiene and safety. The water-cooled conveyor belt is used to convey the cake embryo to the baking oven, solving the problem that the temperature of the conveyor belt continuously rises during the cycle through the baking oven. The cooling water in the water tank can timely cool the conveyor belt by water cooling, effectively extending the service life of the conveyor belt and avoiding the influence of the high-temperature surface of the conveyor belt on the cake embryo, preventing the occurrence of quality problems such as uneven baking, and effectively ensuring the taste of the baked cake.

[0031] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific implementation methods.

[0032] A water-cooled pancake conveying and baking device includes a frame 1. An open water tank 2 is arranged below the head end of the frame 1, and a tensioning roller 3 is rotatably installed in the open water tank 2. A driving roller 4 is rotatably installed above the head end of the frame 1, and a belt pulling roller 5 is rotatably installed above the tail end of the frame 1. A conveyor belt 6 is installed on the frame 1 between the tensioning roller 3, the driving roller 4, and the belt pulling roller 5.

[0033] Among them, a conveyor driving roller 16 for driving the conveyor belt 6 to rotate is rotatably installed inside the frame 1. A driving roller sprocket 15 is installed on one end roller shaft of the conveyor driving roller 16. A motor 13 is installed inside the frame 1 below the conveyor driving roller 16. A motor sprocket 14 is installed on the driving shaft of the motor 13. The motor sprocket 14 and the driving roller sprocket 15 are connected by chain drive.

[0034] An inclined water receiving tank 12 is installed inside the frame 1 below the conveyor belt 6. The low end of the water receiving tank 12 is lapped on the open mouth of the open water tank 2. To ensure that the cooling water in the open water tank 2 can continuously cool the conveyor belt 6, the water temperature of the open water tank 2 needs to be controlled. The open water tank 2 is also connected to a cooling water inlet pipe, and a solenoid valve is installed on the cooling water inlet pipe. A temperature sensor alarm is installed on the frame 1, and the temperature measuring probe of the temperature sensor alarm is arranged inside the open water tank 2. The controller of the temperature sensor alarm is electrically connected to the solenoid valve. When the temperature in the open water tank 2 is too high and reaches the threshold set by the temperature measuring probe of the temperature sensor alarm, the temperature sensor alarm will give an alarm, and the controller controls the solenoid valve to open the cooling water pipeline, and the cooling water pipeline replenishes low-temperature cooling water to the open water tank to ensure the water-cooling effect.

[0035] A knife roller mechanism 7 for rolling and cutting the pancake embryo, a scrap recycling mechanism 8 for recycling the dough, and an oven 10 for baking the pancake embryo to maturity are sequentially installed on the frame 1 above the conveyor belt 6 along the conveying direction.

[0036] In this embodiment, the cutter roller mechanism 7 includes a cutter roller frame 18 erected above the conveyor belt 6. A cutter roller 17 adapted to be in contact with the conveyor belt 6 is rotatably installed on the cutter roller frame 18 through a spring support structure 19. Cutting tools for cutting out cake embryos from the dough sheet are provided on the roller surface of the cutter roller 17.

[0037] The waste material recycling mechanism 8 includes a waste material conveying support 20 erected above the conveyor belt 6 and connected to the machine frame 1. A dough rolling roller 27 spanning the conveyor belt 6 is rotatably connected to the upper part of the waste material conveying support 20. One end of the dough rolling roller 27 is connected to a dough rolling motor 21. A waste material conveyor belt 26 is installed between the waste material conveying support 20 and the machine frame 1 above the conveyor belt 6 and is vertically arranged with respect to the conveyor belt 6. A conveying roller 22 at one end of the waste material conveyor belt 26 is rotatably installed on the waste material conveying support 20, and the end of the conveying roller 22 is in transmission connection with a waste material conveying motor 25 through a sprocket 23 and a chain 24.

[0038] The baking oven 10 is erected and installed above the conveyor belt 6 through a mounting frame 9, and the distance between the baking oven 10 and the conveyor belt 6 is less than or equal to the thickness of the cake embryo. A receiving mesh chain 11 is further connected between the baking oven 10 and the waste material recycling mechanism 8 on the mounting frame 9. After the small cakes are baked, they automatically fall onto the receiving mesh chain 11 and are conveyed away.

[0039] When the cake embryo on the conveyor belt 6 passes by the rotating baking oven 10, it will adhere to the baking oven 10 and be baked to maturity by the high temperature of the baking oven. When the baking oven 10 rotates to the lowest position and contacts the cake embryo, it will squeeze the conveyor belt 6. To prevent the conveyor belt 6 from being deformed due to long-term force extrusion, a support platform 28 for supporting the conveyor belt 6 is provided between the upper and lower conveyor belts 6 directly below the baking oven 10 inside the machine frame 1.

[0040] The working process of the present utility model:

[0041] By providing an open water tank 2 with cooling water inside, the conveyor belt 6 extends downward through a tensioning roller 3 into the open water tank 2, so that the overheated conveyor belt 6 circulating through the baking oven 10 can enter the open water tank 2 for cooling.

[0042] The stretched dough sheet starts to be conveyed backward from the conveyor belt 6 at the head end of the machine frame 1. When the dough sheet passes through the cutter roller mechanism 7, the cutter on the surface of the forming cutter roller 17 rolls and cuts the dough sheet into the shape of the designed cake embryo. The cut dough sheet is continuously conveyed forward. When passing through the waste material recycling mechanism 8, the dough rolling roller 27 rolls up the excess dough sheet and drops it onto the waste material conveyor belt 26, and conveys and recycles the excess dough sheet. The recycled dough sheet can be put into a dough pressing machine for secondary processing to avoid waste.

[0043] The cut and formed cake embryo is sent to the bottom of the baking oven 10 through the conveyor belt 6. Since the furnace body of the baking oven 10 is rotating, the cake embryo is attached to the outer wall of the baking oven 10 and will automatically fall onto the receiving mesh chain 11 and be conveyed away as the baking oven 10 rotates.
