Description

Technical Field

[0001] The utility model relates to the technical field of food oil spraying equipment, and particularly relates to an oil spraying machine for dry cakes. Background Art

[0002] Since baked foods are prone to sticking to the baking trays in contact with them during the baking process, before baking, release oil is usually sprayed into the placement grooves on the baking trays for accommodating the dough embryos, so as to avoid the situation that the baked foods stick to the baking trays after baking.

[0003] Most existing oil spraying machines are used to spray oil on baking trays. The Chinese utility model patent with the publication number CN218245379U discloses an oil spraying machine, which includes a frame. A conveying mechanism for driving the baking tray to move on the frame is arranged on the frame. An oil spraying mechanism for spraying oil on the baking tray located on the conveying mechanism is arranged at the middle part of the frame. It also includes a control box for controlling the conveying mechanism and a control cabinet for controlling the oil spraying of the oil spraying mechanism. During the oil spraying operation, the conveying mechanism is controlled by the control box, and then the baking tray is driven to move below the oil spraying mechanism, so as to realize automatic oil spraying on the baking tray, saving labor costs and improving the oil spraying efficiency.

[0004] However, in practical applications, since the oil spraying machine, the dough injecting machine and the rotary oven are placed in the same workshop, a large amount of heat is emitted during the operation of each device (especially the rotary oven), which causes the temperature of the workshop to rise. In order to reduce the temperature of the workshop, multiple high-power industrial exhaust fans are often installed in the workshop. When these high-power industrial exhaust fans are operating, part of the oil mist sprayed by the oil spraying machine will be sucked away, resulting in the release oil not being fully attached to the baking tray, and then the situation of sticking to the baking tray after baking occurs; and in the process of oil spraying by the existing oil spraying equipment, there will also be a situation where some placement grooves of the baking tray are not sprayed, resulting in the situation that the baked food sticks to the baking tray.

[0005] In view of this, the inventor of the present case has conducted in-depth research on the above problems, and thus this case has been generated. Content of the Utility Model

Detailed implementation manners

[0027] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Refer to Figures 1 to 5 , an oil spraying machine for dry cakes, comprising a long strip-shaped frame 10, the bottom surface of the frame 10 is provided with a plurality of supporting legs 14 for support. Taking the length direction of the frame 10 as the left-right direction, the top surface of the frame 10 is convexly provided with a conveying track 11 arranged horizontally along the left-right direction. A movable baking tray 12 is provided on the conveying track 11. Since driving the baking tray 12 to move through the conveying track 11 is a conventional technical means in the art, and the improvement point of this solution does not lie in this either, so it will not be elaborated in detail here; a "C"-shaped protective cover 20 is provided in the middle of the frame 10. A controller 30 fixedly connected to the frame 10 is provided on the right side of the protective cover 20. The left side wall and the right side wall of the protective cover 20 are respectively detachably connected with a baffle 40. A rectangular observation window is penetrated through the middle of each baffle 40, and a transparent glass 41 is fixedly embedded on the inner wall of the observation window; a protective plate 50 arranged along the front-back direction and detachably connected to the conveying track 11 is provided below the protective cover 20. A plurality of through holes 51 arranged at intervals along the front-back direction are opened on the top surface of the protective plate 50, and an installation rod 21 fixedly connected to the protective cover 20 is provided above the protective plate 50. A plurality of oil outlet pipes 22 arranged at intervals along a straight line and communicated with an external oil storage tank (not shown in the figure) are provided on the left side surface of the installation rod 21. The bottom end of each oil outlet pipe 22 is provided with a nozzle 23 extending into the through hole 51; and a slot 52 is further opened on the front side wall of the protective plate 50. A photoelectric sensor 60 electrically connected to the controller 30 is provided between the outside of the slot 52 and the protective cover 20, and an audible and visual alarm 70 is electrically connected to the top of the controller 30.

[0029] By providing the protective cover 20 and the protective plate 50, the oil mist ejected by the nozzle 23 can be prevented from being sucked away by the exhaust fan in the workshop, and the photoelectric sensor 60 can also send a signal to the controller 30 when detecting that the nozzle 23 leaks oil spraying, and then the controller 30 controls the audible and visual alarm 70 to emit an alarm sound, so as to remind the staff that there is a situation where the baking tray 12 is not oil-sprayed or partially not oil-sprayed, and to avoid the adhesion between the baked food and the baking tray 12.

[0030] Refer to Figures 1 to 5, on both sides of the left side wall and both sides of the right side wall of the protective cover 20, two vertically arranged first dovetail-shaped protrusions 24 are respectively protruded, and a stop block 25 is arranged at the bottom end of each first dovetail-shaped protrusion 24; on the side of each baffle 40 facing the protective cover 20, a first dovetail-shaped groove 42 for engaging with the first dovetail-shaped protrusion 24 is recessed. Through such a setting, the disassembly and assembly can be conveniently carried out when the baffle 40 needs to be cleaned and maintained.

[0031] Referring to Figures 1 to 7 , the nozzle 23 is spherical, and the diameter of the nozzle 23 is smaller than the diameter of the through hole 51. In this way, when the nozzle 23 enters the through hole 51, the dispersion of the oil mist can be reduced. There is a spacing for the baking tray 12 to pass between the bottom end of the baffle 40 and the top surface of the conveying track 11. The top surface of the baking tray 12 is recessed with a plurality of recesses 121 arranged at intervals, and the recesses 121 are used to accommodate the dough pieces. When the baking tray 12 moves below the protection plate 50, the plurality of recesses 121 on the baking tray 12 are respectively located below the plurality of nozzles 23; the protection plate 50 includes two parallel vertical plates 53 and a horizontal plate 54 connected between the two vertical plates 53, and the above-mentioned through hole 51 is opened on the horizontal plate 54; on the top surface of the frame 10, a limiting edge 13 arranged horizontally in the left-right direction is opened, and on the top surface of the limiting edge 13 below the protective cover 20, a second dovetail-shaped protrusion 131 arranged horizontally in the left-right direction is protruded. Second dovetail-shaped grooves 55 for engaging with the second dovetail-shaped protrusion 131 are recessed inwardly at the bottom ends of the two vertical plates 53. Through such a setting, the protection plate 50 can be conveniently disassembled and installed.

[0032] On the frame 10 of the present utility model, a protective cover 20 is provided. Below the protective cover 20, a detachable protection plate 50 is provided, and a controller 30 and an audible and visual alarm 70 are also provided on one side of the protective cover 20. Among them, a plurality of through holes 51 for the nozzle 23 to enter are opened on the top surface of the protection plate 50, and a slot 52 is also opened on the front side wall of the protection plate 50. An optoelectronic sensor 60 electrically connected to the controller 30 is provided between the outside of the slot 52 and the protective cover 20. Through such a setting, when the conveying track 11 drives the baking tray 12 to move below the protection plate 50, the protection plate 50 and the protective cover 20 can form a double protection to prevent the oil mist ejected by the nozzle 23 from being sucked away by the exhaust fan. At the same time, when the optoelectronic sensor 60 detects that the nozzle 23 has missed spraying, it can send a signal to the controller 30, and then the controller 30 controls the audible and visual alarm 70 to emit an alarm sound to remind the staff that there is a situation where the baking tray 12 has not been oiled or partially not oiled, so as to avoid the adhesion between the baked food and the baking tray.

[0033] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
