Description

Technical Field

[0001] The utility model relates to the technical field of dough kneading equipment, in particular to a dough kneading device for making pastries. Background Art

[0002] With the continuous development of the catering industry, pastries, a popular food among consumers, are attracting increasing attention to their production process. Kneading dough is a crucial step in traditional pastry making, directly affecting the taste and quality of the pastries. Currently, kneading dough is often done manually or by machine.

[0003] A search revealed a Chinese patent document, publication number CN214962256U, that discloses an automatic dough kneading device for processing pastry products. After kneading is complete, the bottom plate is withdrawn, allowing the dough in the mixing chamber to fall onto the surface of a first conveyor belt. The first conveyor belt then moves, causing the dough to fall onto the surface of a second conveyor belt. Simultaneously, the second conveyor belt kneads the dough over first and second kneading rollers, where it is kneaded. The dough is then repeatedly transported by the first conveyor belt, completing the kneading process.

[0004] However, the above-mentioned dough kneading device still has certain defects in actual use: due to the certain stickiness of the dough, the dough will partially adhere to the first and second conveyor belts during the kneading process, which not only makes the conveyor belts difficult to clean but also leads to waste. Therefore, we propose a dough kneading device for pastry making to solve the above problem. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the utility model provides a dough kneading device for pastry making, which has the advantages of automatically adding flour during the kneading process so that the flour adheres to the dough, thus preventing the dough from adhering to the conveyor belt, and can also recycle flour, thereby solving the above technical problems.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dough kneading device for making pastries, comprising a shell, wherein a No. 1 conveyor belt and a No. 2 conveyor belt are arranged inside the shell, and a flour box is installed at the top position of the inner wall of the shell, the interior of the flour box is rotatably connected to a roller, the outer surface of the roller is fixedly connected to a plurality of bristles, both ends of the roller are fixedly connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a large pulley, the inner wall of the shell is rotatably connected to the dough kneading roller, one end of the dough kneading roller is fixedly connected to a driven gear, the driven gear is meshed with a driving gear, the end face of the driven gear is fixedly connected to a small pulley through a shaft, the outer surface of the small pulley is driven and connected to a synchronous belt, the inner wall of the shell is fixedly connected to slide rails on both sides, and the outer surface of the slide rails is slidably connected to a receiving tray.

[0009] Preferably, the No. 1 conveyor belt and the No. 2 conveyor belt extend from the interior of the shell, and the No. 1 conveyor belt and the No. 2 conveyor belt are connected to the outer surface of the shell by bolts to form mounting plates, and a material guide plate is connected to the inner wall of the shell.

[0010] Through the above technical solution, the No. 1 conveyor belt and the No. 2 conveyor belt are connected to the shell using the mounting plate. During the dough kneading process, the dough is first placed on the No. 1 conveyor belt, which conveys the dough into the shell. Since the guide plate is located above the kneading roller, the dough will pass through the gap between the kneading roller and the No. 1 conveyor belt under the continuous conveyance of the No. 1 conveyor belt, so that the dough is squeezed and gradually falls onto the No. 2 conveyor belt, which conveys the dough out of the shell. Then, the dough on the No. 2 conveyor belt is manually placed back on the No. 1 conveyor belt, and the dough is kneaded in this way over and over again.

[0011] Preferably, the shaft end of one roller shaft of the No. 1 conveyor belt is connected to the driving gear, and a cover is provided on the outer surface of the driving gear and the driven gear, and the cover is mounted on the outer surface of the shell by screws.

[0012] Through the above technical solution, the No. 1 conveyor belt drives its roller shaft to rotate through the motor, and the roller shaft drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, so that the driven gear drives the kneading roller to rotate. Since the kneading roller is close to the end of the No. 1 conveyor belt located inside the shell and a gap is provided, the kneading roller cooperates with the No. 1 conveyor belt to extrude and knead the dough.

[0013] Preferably, the large pulley and the small pulley are connected via a synchronous belt transmission, and the transmission ratio between the large pulley and the small pulley is 2:1.

[0014] Through the above technical solution, when the driven gear rotates, it can drive the small pulley to rotate, and the small pulley drives the large pulley to rotate through the synchronous belt, and the large pulley drives the roller to rotate. Dry flour is put into the flour box, and when the roller rotates, it can drive multiple bristles on its outer surface to rotate, so that the dry flour in the flour box can be sprinkled out step by step. Once the No. 1 conveyor belt drives the dough through the flour box, dry flour can be sprinkled on its outer surface, which can prevent the dough from sticking to the kneading roller, and can also prevent the dough from sticking to the outer surfaces of the No. 1 conveyor belt and the No. 2 conveyor belt, thereby avoiding quality problems and waste.

[0015] Preferably, a support frame is installed at the bottom of the shell, and a cover plate is hinged on the top of the shell, and a handle is fixedly connected to the top surface of the cover plate.

[0016] Through the above technical solution, the opening at the top of the shell can be sealed by setting a cover to prevent dust and the like from entering the flour box; and dry flour can be added to the flour box through the opening at the top of the shell by opening the cover.

[0017] Preferably, two groups of slide rails and receiving trays are provided, one receiving tray is located below the No. 1 conveyor belt, and the other receiving tray is located below the No. 2 conveyor belt.

[0018] Through the above technical solution, dry flour is continuously added during the kneading process, so that the dry flour is scattered on the dough, and the dough will attach some dry flour to conveyor belt No. 1 and conveyor belt No. 2. Through the circular motion, some dry flour on conveyor belt No. 1 and conveyor belt No. 2 will fall onto the receiving tray, so that some dry flour can be recovered.

[0019] Compared with the prior art, the present invention provides a dough kneading device for making pastries, which has the following beneficial effects:

[0020] 1. The utility model places the dough on the No. 1 conveyor belt, which conveys the dough into the interior of the shell. Since a material guide plate is provided above the kneading roller, the dough passes through the gap between the kneading roller and the No. 1 conveyor belt under continuous conveyance by the No. 1 conveyor belt, so that the dough is squeezed and gradually falls onto the No. 2 conveyor belt, which conveys the dough out of the shell. Then, the dough on the No. 2 conveyor belt is manually placed back onto the No. 1 conveyor belt, and the dough is kneaded repeatedly, thereby reducing the burden of manual kneading.

[0021] 2. In the present invention, when the driven gear rotates, the small pulley can be driven to rotate, and the small pulley drives the large pulley to rotate through the synchronous belt, and the large pulley drives the roller to rotate. Dry flour is put into the flour box, and when the roller rotates, it can drive multiple bristles on its outer surface to rotate, so that the dry flour in the flour box can be sprinkled out step by step. Once the No. 1 conveyor belt drives the dough through the flour box, dry flour can be sprinkled on its outer surface, which can prevent the dough from adhering to the kneading roller, and can also prevent the dough from adhering to the outer surfaces of the No. 1 conveyor belt and the No. 2 conveyor belt, thereby avoiding quality problems and waste.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 5A dough kneading device for making pastries comprises a shell 1, a No. 1 conveyor belt 2 and a No. 2 conveyor belt 3 are arranged inside the shell 1, and a flour box 4 is installed at the top position of the inner wall of the shell 1, the inside of the flour box 4 is rotatably connected to a roller 5, the outer surface of the roller 5 is fixedly connected to a plurality of bristles 6, both ends of the roller 5 are fixedly connected to a rotating shaft 7, one end of the rotating shaft 7 is fixedly connected to a large pulley 8, a dough kneading roller 9 is rotatably connected to the inner wall of the shell 1, one end of the dough kneading roller 9 is fixedly connected to a driven gear 10, the driven gear 10 is meshed with a driving gear 11, a small pulley 12 is fixedly connected to the end surface of the driven gear 10 through a shaft, the outer surface of the small pulley 12 is transmission-connected to a synchronous belt 13, slide rails 14 are fixedly connected to both sides of the inner wall of the shell 1, and the outer surface of the slide rails 14 is slidably connected to a receiving tray 15.

[0030] Specifically, the No. 1 conveyor belt 2 and the No. 2 conveyor belt 3 extend from the interior of the housing 1, and the No. 1 conveyor belt 2 and the No. 2 conveyor belt 3 are connected to the outer surface of the housing 1 by bolts through mounting plates 16. The inner wall of the housing 1 is connected to a guide plate 19. The advantage is that the No. 1 conveyor belt 2 and the No. 2 conveyor belt 3 are connected to the housing 1 using the mounting plates 16. During the dough kneading process, the dough is first placed on the No. 1 conveyor belt 2, which then conveys the dough into the interior of the housing 1. Since the guide plate 19 is located above the kneading roller 9, the dough passes through the gap between the kneading roller 9 and the No. 1 conveyor belt 2 under the continuous conveyance of the No. 1 conveyor belt 2. In this way, the dough is squeezed and gradually falls onto the No. 2 conveyor belt 3. The No. 2 conveyor belt 3 then conveys the dough out of the interior of the housing 1. The dough on the No. 2 conveyor belt 3 is then manually placed back onto the No. 1 conveyor belt 2. This cycle of kneading the dough is repeated.

[0031] Specifically, the shaft end of one roller of the No. 1 conveyor belt 2 is connected to the driving gear 11. The outer surfaces of the driving gear 11 and the driven gear 10 are provided with a cover 17, which is mounted on the outer surface of the housing 1 via screws. The advantage is that the No. 1 conveyor belt 2 is driven by the motor to rotate its roller, which in turn drives the driving gear 11, which in turn drives the driven gear 10, which in turn drives the kneading roller 9. Because the kneading roller 9 is close to the end of the No. 1 conveyor belt 2 located inside the housing 1 and is provided with a gap, the kneading roller 9 can cooperate with the No. 1 conveyor belt 2 to extrude and knead the dough.

[0032] Specifically, the large pulley 8 and the small pulley 12 are connected via a synchronous belt 13 , and the transmission ratio between the large pulley 8 and the small pulley 12 is 2:1. The advantage is that when the driven gear 10 rotates, it can drive the small pulley 12 to rotate, and the small pulley 12 drives the large pulley 8 to rotate through the synchronous belt 13, and the large pulley 8 drives the roller 5 to rotate, and dry flour is put into the flour box 4. When the roller 5 rotates, it can drive the multiple bristles 6 on its outer surface to rotate, so that the dry flour in the flour box 4 can be sprinkled out step by step. Once the No. 1 conveyor belt 2 drives the dough through the flour box 4, dry flour can be sprinkled on its outer surface, which can prevent the dough from adhering to the kneading roller 9, and can also prevent the dough from adhering to the outer surfaces of the No. 1 conveyor belt 2 and the No. 2 conveyor belt 3, avoiding quality problems and waste. By setting the transmission ratio of the large pulley 8 and the small pulley 12 to 2:1, the small pulley 12 rotates two circles and the large pulley 8 can rotate one circle, so that the flour does not fall too fast.

[0033] Specifically, a support frame is mounted on the bottom of the housing 1, and a cover plate 18 is hingedly connected to the top of the housing 1. The top surface of the cover plate 18 is fixedly connected to the handle. Advantageously, the cover plate 18 can seal the opening at the top of the housing 1, preventing dust and the like from entering the flour box 4. By opening the cover plate 18, dry flour can be added to the flour box 4 through the opening at the top of the housing 1.

[0034] Specifically, two sets of slide rails 14 and receiving trays 15 are provided, one receiving tray 15 being located below conveyor belt 1 2 and the other receiving tray 15 being located below conveyor belt 2 3 . The advantage is that dry flour is continuously added during the kneading process, so that the dry flour is scattered on the dough, and the dough in turn adheres some dry flour to conveyor belts 1 2 and 3 . Through the circular motion, some dry flour on conveyor belts 1 2 and 3 falls onto the receiving tray 15 , thus allowing some dry flour to be recovered.

[0035] When in use, first place the dough on the No. 1 conveyor belt 2, and then convey the dough to the inside of the shell 1 through the No. 1 conveyor belt 2, and drive the driven gear 10 to rotate through the driving gear 11, so that the driven gear 10 drives the kneading roller 9 to rotate. Since the guide plate 19 is arranged above the kneading roller 9, the dough will pass through the gap between the kneading roller 9 and the No. 1 conveyor belt 2 under the continuous conveyance of the No. 1 conveyor belt 2, so that the dough is squeezed and gradually falls onto the No. 2 conveyor belt 3, which conveys the dough out of the inside of the shell 1, and then the No. 2 conveyor belt is manually moved. The dough on 3 is put onto conveyor belt No. 1 2 again, and the kneading of the dough is achieved over and over again; during the kneading process, dry flour is added to the flour box 4. When the roller 5 rotates, it can drive the multiple bristles 6 on its outer surface to rotate, so that the dry flour in the flour box 4 can be sprinkled out step by step. Once conveyor belt No. 1 2 drives the dough through the flour box 4, dry flour can be sprinkled on its outer surface, which can prevent the dough from adhering to the kneading roller 9 and the outer surface of conveyor belt No. 1 2 and conveyor belt No. 2 3, thereby avoiding quality problems and waste.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
