Description

Technical Field

[0001] The invention relates to the technical field of food production equipment, in particular to an egg brushing machine. Background Art

[0002] Moon cakes, pastries and biscuits are a kind of snack made of flour as the main raw material through molding and baking. As gifts and daily use moon cakes or pastries, people take it as a snack or dietary supplement. They are easy to eat and carry, and have become an indispensable food in daily life or festivals.

[0003] In order to improve the taste and flavor, sometimes it is necessary to apply a layer of egg liquid on the pastries or mooncakes before baking. This will make the baked goods taste better and have a strong egg flavor.

[0004] In the existing moon cake and pastry production lines, there is a method of manually applying egg liquid to the surface of the food to be baked using a rolling brush or a soft brush. This method is laborious to apply and cannot meet the large-scale production needs of the factory; the existing production line also uses an egg brush machine to brush the surface of the food to be baked with egg liquid. In order to make the egg liquid brushing more uniform, this egg brush machine usually uses a cross brushing method to brush the egg liquid horizontally and vertically on the surface of the food to be baked. The horizontal egg liquid brushing mechanism and the vertical egg liquid brushing mechanism of this egg brush machine are usually separately arranged and arranged in the transmission direction of the production line. This brushing method causes the egg brush machine to be usually large in size, which will take up a lot of space for smaller food production companies. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an egg brushing machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0006] The solution of the present invention to solve its technical problem is:

[0007] An egg brushing machine comprises a frame, on which a driving device, a brush length changing mechanism and a baking tray rotating mechanism are installed. The driving device, the brush length changing mechanism and the baking tray rotating mechanism are arranged in sequence from top to bottom, and the driving device drives the brush length changing mechanism to move in the vertical and horizontal directions.

[0008] Through the above technical scheme, when the baking tray moves to the baking tray rotating mechanism, the egg brushing machine starts to work, firstly, the egg liquid is brushed horizontally, and the driving device drives the brush length conversion mechanism to move horizontally and vertically, and the food to be brushed on the baking tray is repeatedly brushed with egg liquid horizontally. When the number of repeated egg liquid brushing reaches the specified number, the horizontal egg liquid brushing operation ends; then the baking tray rotating mechanism rotates the baking tray, so that the baking tray rotates 90 degrees on the horizontal plane, and the system controls the length of the brushing part of the brush length conversion mechanism to change, so that the length of the brushing part is suitable for the baking tray after the rotation angle, and then the egg liquid brushing operation is performed longitudinally. The process and method of the longitudinal egg liquid brushing operation and the transverse egg liquid brushing operation are basically the same; after the longitudinal egg liquid brushing operation is completed, the baking tray rotating mechanism drives the baking tray to rotate 90 degrees in the opposite direction, so that the baking tray returns to the state when it enters the egg brushing machine, and then the baking tray is transported out, and the egg brushing machine waits for the next work. The egg brushing machine using this scheme occupies a small space as a whole, and can be applied to food production enterprises with a small area.

[0009] As a further improvement of the above technical solution, an egg liquid fixing rack is installed on the frame, the egg liquid fixing rack is arranged above the baking tray rotating mechanism, the egg liquid fixing rack is arranged on one side of the baking tray rotating mechanism, and the egg liquid tank is fixedly connected to one end of the egg liquid fixing rack close to the baking tray rotating mechanism.

[0010] Through the above technical solution, the egg liquid tank is used to hold the egg liquid, and the brush length changing mechanism dips the egg liquid in the egg liquid tank.

[0011] As a further improvement of the above technical solution, a filtrate cross bar is fixedly connected above the egg liquid tank and is used to scrape off excess egg liquid adhering to the bristle part of the brush length conversion mechanism.

[0012] Through the above technical scheme, after the bristle part of the brush length changing mechanism is dipped in the egg liquid, the driving device drives the brush length changing mechanism to move repeatedly at the filtrate cross bar, so that the bristle part contacts the filtrate cross bar multiple times, and the excess egg liquid adhering to the bristle part is scraped off.

[0013] As a further improvement of the above technical solution, the brush length changing mechanism includes a push plate, a main brush and a lengthening brush, the main brush and the lengthening brush are both arranged below the push plate, the main brush is fixedly connected to the push plate, and a lengthening drive for adjusting the distance between the lengthening brush and the push plate is arranged between the push plate and the lengthening brush, and the lengthening drive is a linear drive.

[0014] Through the above technical solution, after the baking tray rotates, the overall length of the brush length changing mechanism may be greater than the side length in the brushing direction after the baking tray rotates. When the width to be brushed becomes smaller, the lengthening driver can start the lengthening brush to move in the direction of the push plate, and then the driving device drives the brush length changing mechanism to dip in the egg liquid. At this time, the lengthening brush does not dip in the egg liquid, thereby avoiding the lengthening brush dipping in the egg liquid, causing the egg liquid on the lengthening brush to drip when the brush length changing mechanism is brushing the food to be brushed, causing excess egg liquid to be wasted and the surrounding environment of the egg brush machine to become dirty, thereby reducing the waste of egg liquid and ensuring the cleanliness of the environment around the egg brush machine.

[0015] As a further improvement of the above technical solution, there are two lengthening brushes respectively arranged at the two ends of the main brush.

[0016] Through the above technical solution, in order to adapt to the rotation center of the baking tray rotating mechanism, two additional lengthening brushes are respectively arranged at the two ends of the main brush.

[0017] As a further improvement of the above technical solution, the driving device includes a horizontal driving mechanism and a vertical driving mechanism, the horizontal driving mechanism includes a horizontal driving motor, a synchronous belt and two synchronous pulleys, the two synchronous pulleys are installed on the frame and are rotatably connected to the frame, the two synchronous pulleys are driven by the synchronous belt, the horizontal driving motor is fixedly connected to the frame, and the output shaft of the horizontal driving motor is fixedly connected to one of the synchronous pulleys; the vertical driving mechanism includes a mounting plate, a vertical driving motor and a screw, one end of the mounting plate is fixedly connected to the synchronous belt, a motor mounting frame is fixedly connected to the mounting plate, the vertical driving motor is fixedly connected to the motor mounting frame, the output shaft of the vertical driving motor is fixedly connected to the screw, and the end of the screw away from the vertical driving motor is threadedly connected to the brush length conversion mechanism.

[0018] Through the above technical scheme, the horizontal driving mechanism is used to control the horizontal displacement of the brush length changing mechanism, so that the brush length changing mechanism can dip into the egg liquid and repeatedly brush the egg liquid; and the vertical driving mechanism drives the lifting and lowering of the brush length changing mechanism, thereby controlling the contact and separation between the bristle part of the brush length changing mechanism and the food to be brushed, as well as the operation of dipping into the egg liquid.

[0019] As a further improvement of the above technical solution, the baking tray rotating mechanism includes a rotating frame and a rotating driver, the output end of the rotating driver is fixedly connected to the rotating frame, the rotating driver drives the rotating frame to rotate on a horizontal plane, both ends of the rotating frame are rotatably connected to rotating rods, a claw is fixedly connected to the rotating rod, and a positioning driver is hinged on the inner side of the rotating frame, the positioning driver is a linear driver, and the output end of the positioning driver is hinged to the lower end of the claw.

[0020] Through the above technical solution, the clamping claws are used to clamp the baking tray on the rotating rack to avoid relative displacement between the baking tray and the rotating rack when the rotating rack rotates, which affects the subsequent egg liquid coating and subsequent baking tray conveying operations.

[0021] As a further improvement of the above technical solution, the number of claws installed on the same rotating rod is set to at least two, and the multiple claws are arranged along the axis of the rotating rod and are fixedly connected to the rotating rod, and the positioning driver is fixedly connected to the lower end of one of the claws.

[0022] Through the above technical solution, multiple claws clamp multiple positions of the baking tray, making it more difficult for the baking tray to be relatively displaced with the rotating rack.

[0023] As a further improvement of the above technical solution, the baking tray rotating mechanism also includes a lifting driver for lifting the rotating frame and the rotating driver. The lifting driver is a linear driver. The lifting driver is fixedly mounted on the frame. The output end of the lifting driver is fixedly connected to the rotating driver.

[0024] Through the above technical solution, when the baking tray is transported to the egg brushing machine, the lifting drive drives the rotating frame and the rotating mechanism to rise, and then the egg liquid is applied horizontally; when the egg brushing machine completes the horizontal egg liquid application, the rotating mechanism drives the rotating frame to rotate ninety degrees on the horizontal plane to prepare for the subsequent longitudinal egg liquid application.

[0025] The beneficial effects of the present invention are as follows: when the baking tray moves onto the baking tray rotating mechanism, the egg brushing machine starts to work, firstly, the egg liquid is brushed horizontally, the driving device drives the brush length changing mechanism to move horizontally and vertically, and the food to be brushed on the baking tray is repeatedly brushed with egg liquid horizontally, and when the number of repeated egg liquid brushing reaches the specified number, the horizontal egg liquid brushing operation ends; then the baking tray rotating mechanism rotates the baking tray, so that the baking tray rotates 90 degrees on the horizontal plane, and the system controls the length of the brushing part of the brush length changing mechanism to change, so that the length of the brushing part is suitable for the baking tray after the rotation angle, and then the egg liquid brushing operation is performed longitudinally, and the process and method of the longitudinal egg liquid brushing operation and the transverse egg liquid brushing operation are basically the same; after the longitudinal egg liquid brushing operation is completed, the baking tray rotating mechanism drives the baking tray to rotate 90 degrees in the opposite direction, so that the baking tray returns to the state when entering the egg brushing machine, and then the baking tray is transported out, and the egg brushing machine waits for the next work.

In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0037] Reference Figure 1 , an egg brushing machine includes a frame 100. A driving device 200, a brush length changing mechanism 300 and a baking tray rotating mechanism 400 are installed on the frame 100. The driving device 200, the brush length changing mechanism 300 and the baking tray rotating mechanism 400 are sequentially distributed from top to bottom.

[0038] Reference Figure 1The frame 100 includes a control box 110 and legs 120. The number of legs 120 is set to four, and the four legs 120 are respectively arranged at the four corners of the control box 110 and are fixedly connected to the lower surface of the control box 110. A control panel 111 is arranged at one end of the control box 110 in the length direction, and a working status light is arranged at the top of the frame 100. An installation room 130 is arranged on the frame 100, and the installation room 130 and the control panel 111 are distributed along the length direction of the entire frame 100. The driving device 200 is arranged in the installation room 130. The lower part of the frame 100 is set as a working area, and the working area is surrounded by the four legs 120 of the frame 100, the placement plane and the lower end of the control box 110. The brush length changing mechanism 300 and the baking tray rotating mechanism 400 are installed in the working area.

[0039] Reference Figure 1 , wherein the two legs 120 located on the same side as the control panel 111 are respectively provided with fixing members, including two fixing blocks, which are fixedly connected by screws and clamp the legs 120. An egg liquid fixing frame 140 is arranged between the two legs 120, and a strip hole is opened on one end of the egg liquid fixing frame 140, and a fixing screw is penetrated in the strip hole, and the threaded section of the fixing screw is threadedly connected with the fixing block located on the opposite side of the two legs 120, so that the egg liquid fixing frame 140 can be adjusted between the two legs 120. An egg liquid tank 141 is fixedly connected to one end of the egg liquid fixing frame 140 away from the strip hole by screws, and a filtrate cross bar 142 for scraping off the excess egg liquid adhered to the bristle part of the brush length conversion mechanism is fixedly connected above the egg liquid tank 141. A handle is fixedly connected to the side wall of the egg liquid tank 141 away from the baking tray rotating mechanism 400.

[0040] Reference Figure 1 The two opposite supporting legs 120 located in the width direction of the frame 100 are fixedly connected by a first reinforcing rod 150 and a second reinforcing rod 160 . The first reinforcing rod 150 is arranged below the second reinforcing rod 160 and is fixedly connected to the bottom end of the supporting leg 120 .

[0041] Reference Figure 1 The lower end of the first reinforcement rod 150 is fixedly connected with a universal wheel 151 and a support foot pad 152. The relative position between the support foot pad 152 and the placement plane is adjusted by a nut. When the egg brush machine is moved, the support foot pad 152 is adjusted away from the placement plane by the nut, so that the universal wheel 151 abuts against the placement plane, making the transportation of the egg brush machine more labor-saving and convenient; when the egg brush machine is moved to a designated position, the support foot pad 152 is adjusted by the nut so that the support foot pad 152 abuts against the placement plane and is tightly pressed. When the egg brush machine is placed at work, the displacement caused by the vibration of the machine affects the coordination between the egg brush machine and other machines.

[0042] Reference Figure 1 A mounting beam 180 is disposed between the two second reinforcement bars 160 on both sides of the frame 100 in the length direction, and the mounting beam 180 is fixedly connected to the second reinforcement bars 160 via a connecting plate. The baking tray rotating mechanism 400 is fixed on the mounting beam 180 .

[0043] Reference Figure 1 The two opposite legs 120 in the width direction of the frame 100 are fixedly connected by a third reinforcing rod 170. The third reinforcing rod 170 is arranged at the lower end of the bracket, and the two ends of the third reinforcing rod 170 are fixed to the two legs 120 by screws respectively.

[0044] Reference Figure 1 The driving device 200 includes a horizontal driving mechanism 210 and a vertical driving mechanism 220. The horizontal driving mechanism 210 drives the brush length changing mechanism 300 to slide in the horizontal direction, and the vertical driving mechanism 220 drives the brush length changing mechanism 300 to slide in the vertical direction.

[0045] Reference Figure 2 and Figure 3 The horizontal drive mechanism 210 includes a horizontal drive motor 211, a synchronous belt 213 and two synchronous pulleys 212. The horizontal drive motor 211 is fixedly connected to the installation chamber 130, and the output shaft of the horizontal drive motor 211 is fixedly connected to the synchronous pulley 212 near the control panel 111 through a coupling, and the two synchronous pulleys 212 are arranged along the entire length of the frame 100. The synchronous belt 213 is arranged between the two synchronous pulleys 212 and is driven by the two synchronous pulleys 212. In other embodiments, two sets of horizontal drive mechanisms 210 can be provided, and the horizontal drive motors 211 of the two sets of horizontal drive mechanisms 210 are respectively arranged at both ends of the length direction of the installation chamber 130. When the straight section of the synchronous belt 213 located below needs to move in a certain direction, the horizontal drive motor 211 located in that direction rotates, and the horizontal drive motor 211 in the other direction is powered off, so that the straight section of the synchronous belt 213 located below moves in that direction. When it is necessary to move in the other direction, the horizontal drive motor 211 in the other direction rotates. The rotation directions of the two horizontal drive motors 211 are opposite. Or in other embodiments, the horizontal drive mechanism 210 can be provided with two horizontal drive motors 211 which are respectively fixedly connected to two synchronous pulleys 212 through couplings. When the straight section of the synchronous belt 213 located below needs to move in a certain direction, the horizontal drive motor 211 located in that direction rotates, and the horizontal drive motor 211 in the other direction is powered off, so that the straight section of the synchronous belt 213 located below moves in that direction. When it is necessary to move in the other direction, the horizontal drive motor 211 in the other direction rotates. The rotation directions of the two horizontal drive motors 211 are opposite. This method can keep the synchronous belt 213 located below taut in both directions.

[0046] Reference Figure 2 , Figure 3 and Figure 4 The vertical drive mechanism 220 includes a mounting plate 221, a vertical drive motor and a screw 222. The mounting plate 221 is arranged between the two straight sections of the synchronous belt 213, and one end of the mounting plate 221 is fixedly connected to the straight section of the synchronous belt 213 located below by screws. A motor mounting frame is fixedly connected above the mounting plate 221. The motor mounting frame includes four fixing columns 223 and a motor plate 224.

The lower end of the mounting plate 221 is also fixedly connected with a sliding seat 226 by screws. The sliding seat 226 has two ends respectively arranged on the mounting plate 221. The frame 100 is fixedly connected with a slide rail that slides with the sliding seat 226. The cooperation between the sliding seat 226 and the slide rail limits and guides the vertical drive mechanism 220 to prevent the vertical drive mechanism 220 from deflecting due to uneven hands at both ends of the mounting plate 221 when the vertical drive mechanism 220 moves, affecting the normal operation of the egg brushing machine. The two ends of the mounting plate 221 are also fixedly connected with a sliding sleeve 227 by screws. A guide rod 228 is inserted into the sliding sleeve 227, and the guide rod 228 is slidably connected to the sliding sleeve 227. A detection plate 229 is fixedly connected to the mounting plate 221 by screws. The detection plate 229 extends downward. Two detection heads are fixedly connected to the detection plate 229, and the detection ends of the two detection heads are both facing the brush length conversion mechanism 300. The two detection heads are vertically distributed and fixedly connected to the detection plate 229. The two detection heads are used to detect the descending position of the brush length conversion mechanism 300, and the lifting and lowering of the brush length conversion mechanism 300 is controlled by the control system. In other embodiments, the vertical drive mechanism 220 can realize the lifting and lowering of the brush length conversion mechanism 300 through a linear drive such as a linear cylinder or an electric push rod.

[0047] Reference Figure 5The brush length changing mechanism 300 includes a push plate 310, a main brush 320 and a lengthening brush 330. The push plate 310 is fixedly connected with a threaded sleeve 311 by screws, and the threaded sleeve 311 is threadedly connected with the screw rod 222. Through holes are provided at both ends of the push plate 310, and the guide rod 228 is inserted into the through holes. The guide rod 228 is relatively fixed with the push plate 310 by two locking members, and the two locking members are respectively arranged at the upper and lower sides of the push plate 310 and the two locking members are in contact with the push plate 310. The main brush 320 includes a first fixed plate 321 and a first brush 322, and the brush handles of the first fixed plate 321 and the first brush 322 are fixedly connected by screws. The lengthening brush 330 has two ends respectively arranged at the main brush 320, and a lengthening driver 340 is arranged between the lengthening brush 330 and the push plate 310, and the lengthening driver 340 is arranged as a double-rod linear cylinder. The lengthening brush 330 includes a second fixing plate 331 and a second brush 332. The cylinder of the lengthening driver 340 is fixedly connected to the push plate 310, and the output end is fixedly connected to the second fixing plate 331 by screws. The second fixing plate 331 and the brush handle of the second brush 332 are fixedly connected by screws.

[0048] Reference Figure 6 and Figure 7 The baking tray rotating mechanism 400 includes a rotating frame 410, a rotating driver 420, a lifting driver 430 and a mounting seat 440. The rotating driver 420 is a rotating cylinder, and the lifting driver 430 is a linear cylinder. The mounting seat 440 is fixedly connected to the mounting beam 180. The cylinder body of the lifting driver 430 is fixedly connected to the mounting seat 440 and the output end faces upward. The output end of the lifting driver 430 is fixedly connected to the plate body by screws, and the rotating driver 420 is fixedly connected to the plate body and the output end faces upward. The rotating frame 410 is arranged above the rotating driver 420.

[0049] Reference Figure 6 and Figure 7The rotating frame 410 includes a mounting base plate 411 and a side plate 412. The mounting base plate 411 is fixedly connected to the output end of the rotating driver 420, and the side plate 412 is fixed to the opposite ends of the mounting base plate 411 by screws. The two ends of the mounting side plate 412 in the length direction are respectively installed with a rotating rod 413, and the rotating rod 413 is installed between two opposite side plates 412 and is rotatably connected to the two side plates 412. Two claws 414 are fixedly connected to the rotating rod 413, and the two claws 414 are distributed along the length direction of the rotating rod 413 and are symmetrically arranged about the central plane in the length direction of the rotating rod 413. The inner sides of the two side plates 412 are respectively provided with a clamping driver 415, and the clamping driver 415 is set as a linear cylinder, and the cylinder body of the clamping driver 415 is hinged to the side plate 412, and the output shaft is hinged to the lower end of the clamping claw 414. Two positioning drivers 415 are respectively arranged on both sides of the length direction of the rotating frame 410, and are respectively arranged on both sides of the width direction of the rotating frame 410. In other embodiments, the positioning drivers 415 can also be arranged to be three or four and are respectively hinged to different claws 414. A detection device for detecting the baking tray is also installed on the rotating frame 410.

[0050] The implementation principle of this embodiment is as follows: after the baking tray is transported to the egg brushing machine by the conveyor line, the detection device detects that there is a baking tray on the rotating frame 410, and the control system controls the positioning driver 415 to extend, so that the clamping claw 414 and the rotating rod 413 rotate around the axis of the rotating rod 413, and the clamping claws 414 at both ends of the rotating frame 410 in the length direction clamp the baking tray to avoid relative rotation and slippage between the baking tray and the rotating frame 410 during the subsequent rotation of the baking tray. Then the lifting driver 430 lifts the rotating driver 420 and the rotating frame 410, and at the same time the horizontal driving mechanism 210 drives the brush length changing mechanism 300 to move from the origin to above the egg liquid tank 141. When the brush length changing mechanism 300 moves to above the egg liquid tank 141, the vertical driving mechanism 220 drives the brush length changing mechanism 300 to descend and dip into the egg liquid. Then the vertical driving mechanism 220 drives the brush length changing mechanism 300 to rise to the filtrate cross bar 142. Then the horizontal driving mechanism 210 controls the brush length changing mechanism 300 to repeatedly move horizontally several times near the filtrate cross bar 142, so that the excess egg liquid on the first brush 322 and the second brush 332 falls back into the egg liquid tank 141.

[0051] After filtering out the excess egg liquid, the first brush 322 and the second brush 332 on the brush length changing mechanism 300 perform a horizontal brushing operation on the surface of the food to be baked on the baking tray, and at this time, the lowermost bristles of the first brush 322 and the second brush 332 are on the same horizontal line. The horizontal brushing operation requires the bristles of the first brush 322 and the second brush 332 to move back and forth a specified number of times on the surface of the food to be baked.

[0052] After the horizontal egg-brushing operation is completed, the brush length conversion mechanism 300 is driven by the vertical drive device 200 to move upward, and then driven by the horizontal drive mechanism 210 to move toward the egg liquid tank 141. At the same time, the lengthening driver 340 works to make the lengthening brush 330 move upward. At the same time, the rotary driver 420 drives the rotating frame 410 to rotate ninety degrees on the horizontal plane. Then, the operation of dipping the egg liquid and filtering out the excess egg liquid is repeated. Then, the brush length conversion mechanism 300 is driven by the horizontal drive mechanism 210 to the top of the baking tray. Then, the vertical drive device 200 drives the brush length conversion mechanism 300 to descend and start the vertical egg-brushing operation. The vertical egg-brushing operation requires the bristles of the first brush 322 to move back and forth a specified number of times on the surface of the food to be baked.

[0053] When the operation of brushing the egg liquid vertically is finished, the brush length changing mechanism 300 returns to the origin under the joint action of the horizontal driving mechanism 210 and the vertical driving mechanism 220. At the same time, the rotating driver 420 drives the rotating frame 410 to rotate 90 degrees in the opposite direction to the original state, and the lifting driver 430 drives the rotating driver 420 and the rotating disk to descend, so that the lower surface of the baking tray is flush with the subsequent conveyor belt. Subsequently, the clamping driver 415 shortens, so that the clamping claw 414 cancels the clamping of the baking tray.

[0054] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
