Description

Technical Field

[0001] The present invention relates to the technical field of pastry processing equipment, and particularly relates to a pastry sauce spreading machine. Background Art

[0002] When producing pastries such as clamped bread and jam toast, it is necessary to apply a layer of sauce such as jam and cream on the surface of the pastries. The uniformity of the sauce application directly affects the production quality of the pastries, and the sauce application efficiency directly affects the production efficiency of the pastries. Therefore, in order to ensure the production quality of the pastries and improve the production efficiency of the pastries, a pastry sauce spreading machine is specifically designed. Summary of the Invention

[0003] The purpose of the present invention is to provide a pastry sauce spreading machine to solve the above problems, as described in detail below.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A pastry sauce spreading machine provided by the present invention includes a belt conveyor. Control boxes and hoppers are respectively arranged on both sides of the belt conveyor. The belt conveyor is provided with multiple conveyor belts for simultaneously conveying multiple pastries. A gantry and a diverter are sequentially arranged on the belt conveyor along its conveying direction. The diverter has multiple discharge ends extending along the width direction of the belt conveyor, and the discharge ends of the diverter are connected with solenoid valves. The end of the solenoid valve is connected with a spreading head, and the spreading head corresponds to the conveyor belt. The solenoid valve is electrically connected with the control box. A second photoelectric switch is arranged on the surface of the belt conveyor near the solenoid valve, and the second photoelectric switch is electrically connected with the control box for detecting whether the pastry reaches the spreading station;

[0006] A first photoelectric switch is arranged on the surface of the gantry through a connecting frame. The first photoelectric switch corresponds to the conveyor belt, and the first photoelectric switch is electrically connected with the control box for detecting whether there is a pastry on the surface of the conveyor belt;

[0007] The discharge end of the hopper is connected with a metering pump, and the discharge end of the metering pump is connected with the diverter through a conduit for injecting the sauce inside the hopper into the diverter.

[0008] When using the above-mentioned pastry spreading machine for production, place the pastry on the surface of the conveyor belt. The pastry is conveyed towards the spreading head by the belt conveyor. As the belt conveyor conveys, the pastry moves to the spreading station. The second photoelectric switch is triggered and transmits a trigger signal to the control box. The control box controls the operation of the dosing pump and opens the solenoid valve. Under the action of the dosing pump, the sauce inside the hopper enters through the diverter and the solenoid valve and is discharged from the spreading head, thereby spreading the sauce on the pastry, completing the automatic spreading of the sauce. The spreading is stable and uniform, which helps to ensure the quality. The spreading efficiency is high, which helps to improve the production efficiency. By controlling the working frequency of the dosing pump through the control box, the control of the sauce spreading amount is realized. After the set amount of sauce spreading is reached, the control box controls the solenoid valve to close, which can effectively prevent the dosing pump from sucking back in time and causing the sauce spreading to trail, thus avoiding the sauce dropping onto the conveyor belt surface and causing pollution, and can ensure the quality of the sauce spreading. During the conveying process of the pastry by the belt conveyor, it is detected by the first photoelectric switch whether there is a pastry on the conveyor belt surface. When it is detected that there is a pastry on the conveyor belt surface, normal spreading is carried out. When it is detected that there is no pastry on the conveyor belt surface, when this position moves to the coating head, the control box controls the solenoid valve corresponding to this position to close, and no sauce spreading is carried out here, preventing the sauce from falling on the conveyor belt and causing pollution, and at the same time preventing sauce waste.

Specific embodiments

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0030] Referring to Figures 1 - 5 as shown, the present invention provides a pastry sauce spreading machine, including a belt conveyor 1. A control box 2 and a hopper 4 are respectively arranged on both sides of the belt conveyor 1. The conveyor belt 106 of the belt conveyor 1 is provided with multiple strips for simultaneously conveying multiple pastries. A gantry frame 7 and a diverter 5 are sequentially arranged on the belt conveyor 1 along its conveying direction. The discharging end of the diverter 5 is provided with multiple ones, extending along the width direction of the belt conveyor 1, and the discharging end of the diverter 5 is connected with a solenoid valve 10. The end of the solenoid valve 10 is connected with a coating head 6. The coating head 6 corresponds to the conveyor belt 106. The solenoid valve 10 is electrically connected with the control box 2. A second photoelectric switch 13 is arranged on the surface of the belt conveyor 1 close to the solenoid valve 10. The second photoelectric switch 13 is electrically connected with the control box 2 for detecting whether the pastry reaches the spreading station;

[0031] The surface of the door frame 7 is provided with a first photoelectric switch 8 through a connecting frame 801. The first photoelectric switch 8 corresponds to the conveyor belt 106. The first photoelectric switch 8 is electrically connected to the control box 2 and is used to detect whether there are cakes on the surface of the conveyor belt 106.

[0032] The discharge end of the hopper 4 is connected to an injection pump 3 , and the discharge end of the injection pump 3 is connected to the diverter 5 through a conduit, so as to inject the sauce in the hopper 4 into the diverter 5 .

[0033] As an optional embodiment, the belt conveyor 1 includes a conveying frame 101, and conveying shafts 102 are rotatably provided at both ends of the conveying frame 101 in the length direction. A plurality of pulleys 103 are provided on the conveying shaft 102, and the pulleys 103 are evenly distributed along the axial direction of the conveying shaft 102. A conveyor belt 106 is meshed and connected between two corresponding pulleys 103 on the two conveying shafts 102. A conveying motor 104 is provided on the outer side of the conveying frame 101, so that the output end of the conveying motor 104 is connected to any conveying shaft 102, and a support plate 107 is provided inside the conveying frame 101. The support plate 107 is located inside the annular structure formed by the conveying belt 106 and contacts the bottom surface of the conveying belt 106. In this arrangement, the conveying motor 104 drives the conveying shaft 102 to rotate, and drives the conveying belt 106 through the pulleys 103, so that the conveying belt 106 transports the cakes.

[0034] Guide plates 9 are provided on the surface of the support plate 107. The guide plates 9 are symmetrically distributed on both sides of the conveyor belt 106 in groups of two. The ends of the two guide plates 9 close to the front end of the belt conveyor 1 are inverted "figure eight structure". The width of the conveyor belt 106 is adapted to the width of the pastries, and the two guide plates 9 are in contact with both sides of the conveyor belt 106 respectively. In this way, the pastries are guided by the guide plates 9 to ensure that the pastries are accurately located on the surface of the conveyor belt 106, thereby ensuring that the subsequent sauce is accurately and evenly applied.

[0035] Positioning blocks 105 are evenly arranged on the surface of the conveyor belt 106 along its length direction. In this way, the positioning blocks 105 are used to position the cakes to ensure accurate placement. At the same time, when applying sauce, the positioning blocks 105 are used to fix the cakes to ensure that the cakes move with the conveyor belt 106 and the sauce application can be carried out smoothly.

[0036] On the side of the conveyor frame 101 in the width direction, there are mounting threaded holes 108. On the side of the gantry 7, there are vertical waist-shaped slots 701, and the vertical waist-shaped slots 701 correspond to the mounting threaded holes 108. On the surface of the gantry 7, there are positioning threaded holes 702. On the surface of the connecting frame 801, there are horizontal waist-shaped slots 802. The horizontal waist-shaped slots 802 extend along the conveying direction of the conveyor belt 106 and correspond to the positioning threaded holes 702. With such a setting, the height adjustment of the gantry 7 can be achieved through the cooperation of the vertical waist-shaped slots 701 and the mounting threaded holes 108 with bolts, thereby realizing the height adjustment of the first photoelectric switch 8. The position adjustment of the connecting frame 801 along the length direction of the conveyor belt 106 can be adjusted through the cooperation of the positioning threaded holes 702 and the horizontal waist-shaped slots 802 with bolts, thereby realizing the horizontal position adjustment of the first photoelectric switch 8. By adjusting the height and horizontal position of the first photoelectric switch 8, it is ensured that the first photoelectric switch 8 accurately detects whether there is a pastry placed, guaranteeing the detection accuracy.

[0037] On both sides of the conveyor frame 101 in the width direction, there are fixed plates 11 provided through columns. The diverter 5 is rotatably installed between the two fixed plates 11 through a rotating shaft 501. On the side of the fixed plate 11 close to the conveyor belt 106, there is a locking member 12 for locking and fixing the rotating shaft 501. With such a setting, the angle adjustment of the diverter 5 is realized through the rotating shaft 501, so that the diverter 5 drives the paint head to tilt, adjusting the height between the discharge end of the paint head and the conveyor belt 106. The rotating shaft 501 is locked and fixed through the locking member 12, realizing the height fixation of the paint head, which can meet the sauce coating requirements of pastries with different heights and ensure the coating effect.

[0038] The locking member 12 includes a clamp 1201. There are two clamps 1201 in total, which are rotatably connected to the side of the fixed plate 11 close to the conveyor belt 106. The two clamps 1201 rotate relative to each other to form a closed circular structure. The movable ends of the two clamps 1201 are both provided with connecting plates 1202. Through holes 1203 and limiting slots 1205 are respectively penetrated on the surfaces of the two connecting plates 1202. A stud 1204 is rotatably arranged inside the through hole 1203, and the stud 1204 corresponds to the limiting slot 1205. A fastening nut 1206 is threadedly connected to the outside of the stud 1204. With such a setting, the stud 1204 is screwed into the limiting slot 1205, and the fastening nut 1206 is screwed, so that the fastening nut 1206 is in close contact with the connecting plate 1202, thereby locking and fixing the rotating shaft 501 through the two clamps 1201.

[0039] The inner wall of the clamp 1201 is provided with a rubber pad.

[0040] A wire connecting rod 1101 is connected between the upper surfaces of the two fixed plates 11. With such a setting, the connecting wire between the solenoid valve 10 and the control box 2 is fixed on the wire connecting rod 1101 through a binding rope, preventing the connecting wire from contacting the pastries and ensuring food safety.

[0041] With the above structure, during production, the pastries are placed on the surface of the conveyor belt 106, and the pastries are conveyed towards the coating head 6 by the belt conveyor 1. As the belt conveyor 1 conveys, the pastries move to the coating station. The second photoelectric switch 13 is triggered and transmits the trigger signal to the control box 2. The control box 2 controls the injection pump 3 to work and the solenoid valve 10 to open. Under the action of the injection pump 3, the sauce inside the hopper 4 enters through the flow divider 5 and the solenoid valve 10 and is discharged from the coating head 6, thereby coating the sauce on the pastries, completing the automatic coating of the sauce. The coating is stable and uniform, which helps to ensure the quality. The coating efficiency is high, which helps to improve the production efficiency. By controlling the working frequency of the injection pump 3 by the control box 2, the control of the sauce coating amount is realized. After the set amount of sauce coating is reached, the control box 2 controls the solenoid valve 10 to close, which can effectively prevent the injection pump 3 from sucking back in time and causing the sauce coating to trail, thereby avoiding the sauce from dropping onto the surface of the conveyor belt 106 and causing pollution, and can ensure the sauce coating quality. During the process of the belt conveyor 1 conveying the pastries, the first photoelectric switch 8 is used to detect whether there are pastries placed on the surface of the conveyor belt 106. When it is detected that there are pastries on the surface of the conveyor belt 106, normal coating is carried out. When it is detected that there are no pastries on the surface of the conveyor belt 106, when this position moves to the coating head, the control box 2 controls the solenoid valve 10 corresponding to this place to close, and no sauce coating is carried out here, preventing the sauce from falling on the conveyor belt 106 and causing pollution, and at the same time preventing sauce waste.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
